Analysis of Self-Administered Aspirin Post-Chest Pain to Prevent Cardiovascular Mortality

According to the American Heart Association, someone experiences an acute myocardial infarction (AMI) in the United States every 40 seconds, making it a leading cause of mortality. However, a significant number of AMI deaths occur outside the hospital, with delayed access to medical care being a contributing factor. The International Study of Infarct Survival sought to analyze the potential benefits and risks of self-administering aspirin within 4 hours of experiencing severe chest pain to reduce mortality post-AMI.

Dequalinium as Potential Treatment for Bacterial Vaginosis

Bacterial vaginosis (BV), a common and recurrent vaginal infection in females of reproductive age, is typically treated with antibiotics, like metronidazole and clindamycin. However, their adverse effects and risk of antibiotic resistance necessitate alternative treatments. A recent study evaluated the efficacy of dequalinium chloride, an antiseptic with broad-spectrum activity against various microorganisms, as a potential nonantibiotic treatment for BV.

Progestogen Versus Combined Oral Contraceptive for Endometriosis Pain

Endometriosis, affecting up to 1-in-10 women of reproductive age, involves the growth of endometrial-like tissue outside the uterus, leading to severe pelvic pain and infertility. Surgical treatment is common, but recurrence rates are high, with many women undergoing multiple operations. Hormonal treatments, like the combined oral contraceptive pill (COCP) and progestogens, are recommended postsurgery, but it's uncertain which is more effective in preventing pain recurrence.

Perioperative Nivolumab for Non-Small-Cell Lung Cancer

Nivolumab, an antibody targeting programmed death-1, in combination with chemotherapy is standard neoadjuvant treatment for patients with resectable non-small-cell lung cancer (NSCLC). Studies, including the landmark CheckMate 816 trial, showed significant improvements in event-free survival and pathologic complete response with this combination compared to chemotherapy alone. Based on these results, researchers questioned whether a perioperative approach, combining neoadjuvant therapy with nivolumab, followed by surgery and adjuvant therapy, could reduce disease relapse rates, and enhance clinical outcomes by bolstering antitumor immunity.

A Small Risk of Interstitial Lung Disease Found with Use of Nonwarfarin AnticoagulantsA large nationwide population-based retrospective cohort study is the first to investigate the reported increased risk of interstitial lung disease (ILD) in patients with atrial fibrillation receiving direct oral anticoagulants (DOACs). These anticoagulants, which include the direct thrombin inhibitor dabigatran and the factor Xa inhibitors rivaroxaban, apixaban, and edoxaban, have been steadily displacing warfarin as the preferred anticoagulants for stroke prevention in atrial fibrillation. In clinical trials, cough and dyspnea were noted as adverse events, but ILD, a rare event, only became evident in large postmarketing studies and in case reports.READ MORE...Using the Taiwan National Health Insurance Research Database, the cohort study collected data on 106,044 patients (mean age, 73.4; 56.6% men) with nonvalvular atrial fibrillation (NVAF) and no preexisting chronic lung disease who received oral anticoagulation between June 2012 and December 2017; 60.9% of patients received one of the factor Xa inhibitors, 21.2% of patients received dabigatran, and 17.9% of patients received warfarin.After adjusting for patient differences at baseline, the factor Xa inhibitors as a group and individually were associated with a slightly greater risk of ILD compared to warfarin. The rate of incident ILD was 0.29 per 100 patient-years compared to 0.17 per 100 patient-years with warfarin (hazard ratio [HR], 1.54). Apixaban was associated with a rate of 0.35 per 100 patient-years, edoxaban with a rate of 0.37 per 100 patient-years, and rivaroxaban with a rate of 0.27 per 100 patient-years. Dabigatran was not associated with a greater risk of ILD on analysis. Concomitant use with amiodarone, which was frequent in this study, was associated with a higher risk of ILD regardless of the anticoagulant used; hazard ratios were as follows:· factor Xa inhibitors and amiodarone: HR, 1.41· dabigatran and amiodarone: HR, 1.62· warfarin and amiodarone: HR, 1.97Due to this study’s observational nature, it cannot definitively delineate the causal relationships it explores; additional research is needed to explore potential mechanisms. These results shouldn’t discourage clinicians from prescribing these drugs; numerous studies have demonstrated significant benefits with factor Xa inhibitors. On risk-benefit analysis, absolute increases in ILD with factor Xa inhibitors and dabigatran (-0.12 and -0.05 per 100 patient-years, respectively, vs. warfarin) were much smaller than the absolute reduction in ischemic stroke/systemic embolism (0.78 and 0.64 per 100 patient-years, respectively) and major bleeding (0.78 and 1.01 per 100 patient-years, respectively). The authors of the study recommend that clinicians vigilantly monitor any potential adverse lung outcomes associated with use of these drugs but note that there is no need to make any major changes to current practices.

Naloxone reverses the effects of the respiratory depression and sedation produced by opioids; when administered at the first signs of opioid overdose (OD), it can prevent opioid-related deaths.READ MORE...The FDA has announced that it’s taking steps to encourage the development of nonprescription formulations of naloxone as a component of its FDA Overdose Prevention Framework. That framework has four priorities:· Support the primary prevention of overdose by limiting initial prescription drug exposure and inappropriate long-term prescriptions.· Encourage harm reduction through innovative programs (such as this initiative) and education.· Advance development of evidence-based treatment for substance use disorders.· Protect public from unapproved, diverted, or counterfeit drugs that present risk of OD.Naloxone is currently available as a prescription drug in the United States in several dosage strengths and dosage forms. It was originally approved as an injectable product for use by hospital personnel and first responders in the treatment of opioid OD, but increasingly has been used by non-health-care professionals, as initiatives sought to put naloxone into the hands of those who might witness an overdose. Since 2014 the FDA has approved several prescription naloxone drug and device combination products for use in emergency treatment of a known or suspected opioid OD; these are known as “community use” naloxone. In addition, as of 2020, every U. S. state and the District of Columbia have naloxone access laws, with one or more of these features:· Third-party provisions that allow providers to prescribe naloxone to someone not directly at risk of OD; that is, to a caregiver or family member· Standing-order provisions that allow for nonpatient-specific prescriptions· Immunity from civil and criminal prosecutions for prescribers and dispensers.Taken together, community-based naloxone distribution programs and naloxone access laws help to illustrate the potential public health benefits of nonprescription naloxone use.On preliminary assessment, naloxone nasal spray up to 4 mg, as well as naloxone autoinjector for IM or subcut use up to 2 mg, are the best candidates for nonprescription use. These dosage forms are used by most consumers. As of 2021, more than 90% of sales of naloxone were for the nasal spray form, although it should be noted that these sales numbers don’t consider donations of naloxone to community-based distribution programs, which are primarily autoinjector products.Although the benefits of broader use of naloxone are significant, concerns exist with making them available over the counter, such as associated risks that include adverse drug effects and precipitation of opioid withdrawal syndrome. Monitoring for and mitigation of these risks are important. The FDA must ensure that any products developed for nonprescription use are appropriately designed to support the intended users’ needs, including the packaging and labeling, and meet the requirements of the Food Drug and Cosmetic Act, demonstrating a clinically meaningful difference from the prescription product. The FDA has asked for comments on this proposal. (FDA.

S. health care costs, especially out-of-pocket costs for patients, is a major driver for efforts to increase medication price transparency. Real-time prescription benefits (RTPB), an electronic clinical decision support tool, provides patient- and medication-specific out-of-pocket information to prescribers at the point of use. A study published in JAMA Internal Medicine demonstrates that such medication price transparency solutions that make cost information available to the prescriber and recommend clinically appropriate alternatives can be an effective tool for generating savings.READ MORE...In the cluster randomized trial, conducted in medical practices in a large academic health system in New York City, all outpatient prescriptions written were randomly assigned to a control arm or to an RTPB recommendation arm. Analysis was limited to those medications for which the tool could recommend an available alternative. Of the 867,757 outpatient prescriptions written at the practices over the study period (January to July 2021), 4.2% (36,419) met the criteria for analysis.If a prescription was randomized to the RTPB recommendation arm, the RTPB system recommended alternatives: either a different medication, different length of prescription, and/or a different choice of pharmacy. The prescriber could then opt for either the initial order or one of the recommended options. Electronic health record data were used to analyze the effect of the intervention on prescribing, both on out-of-pocket patient costs as well as on use of mail order pharmacy or 90-day supplies. Out-of-pocket costs includes any copay, coinsurance, and deductibles the patient is responsible for under their prescription benefits plan.The average out-of-pocket costs for a 30-day supply of medication in the intervention arm was $39.90; in the control arm, it was $67.80. Use of the RTPB recommendations resulted in an adjusted 11.2% reduction in costs. Mail-order pharmacy use was 9.6% in the intervention group and 7.6% in the control group; no differences were found in rate of use of 90-day medication supply.It’s hoped that, by controlling the patient’s out-of-pocket costs, the RTPB system can improve adherence and health outcomes. Further research will be needed to understand the impact of the system on other outcomes, such as prescribing behavior and adherence. (Desai, S. M., et al. (2022).

Drug News Abstracts - November 2022
Amifampridine an Effective Treatment for Spinal Muscle AtrophySpinal muscular atrophy (SMA) is an autosomal recessive disease caused by mutations in the survival motor neuron 1 (SMN1) gene, which encodes the SMN protein. The resulting deficiencies in the SMN protein lead to progressive lower motor neuron degeneration. Clinical severity in this disorder is variable, depending on the presence of the SMN2 gene, which can partially compensate for the SMN protein deficiency. Currently approved treatments for SMA target increasing SMN protein production by SMN2 (nusinersen, risdiplam) or reintroduce the SMN1 gene (gene therapy with onasemnogene abeparvovec).READ MORE...SMA-001, a phase 2, randomized, double-blind, placebo-controlled crossover study, explored a new avenue of treatment for SMA. Patients with SMA Type 3 commonly report fatigue and display a significant response on nerve stimulation studies, signs that suggest impaired neuromuscular junction (NMJ) transmission has a role in the disorder. Amifampridine, a voltage-dependent potassium channel blocker approved for treatment of Lambert-Eaton myasthenic syndrome, prolongs depolarization of the presynaptic NMJ terminal, enhancing neuromuscular transmission and muscle function.From January 2019 to September 2020, SMA-001 enrolled ambulatory patients with SMA Type 3 (able to walk unaided at least 30 meters) who had not received SMN-targeting therapies such as nusinersen. The study included 13 patients, 5 women and 8 men, mean age, 34.5 years. Patients first entered a run-in phase, in which amifampridine was individually titrated up to a maximal effective dose, but no higher than 80 mg/day. Then, those who achieved at least a 3-point improvement in the Hammersmith Functional Motor Score Expanded (HFMSE) were randomly assigned to amifampridine or placebo in a 28-day blinded crossover phase. Patients were assigned to amifampridine/placebo or placebo/amifampridine sequence, which they took for 2 weeks, then switched to the other, with no washout period. The dosage of amifampridine given in this crossover phase was that determined for each individual in the run-in phase. During weekly clinic visits, the HFSME was administered, as were a number of timed tests of motor skills and quality of life assessments.Statistically significant improvement in HFMSE was observed in patients taking amifampridine compared to placebo (mean difference, 0.792). This effect is small, but the fact that the HFMSE score had already improved by at least 3 points before randomization might explain that. However, no significant differences were observed in results of timed tests. In quality-of-life measures, statistically significant improvement was observed in the fatigue subscale, as well as a significant reduction in the expected treatment subscale, but for all other subscale scores, differences were nonsignificant. No serious adverse events were reported, and treatment adherence was high throughout the study.Results provided Class II evidence that amifampridine is safe and effective in treating ambulatory SMA Type 3 patients, demonstrating that fostering neuromuscular transmission can improve fatigability in these patients. The study findings were limited by the small sample size and the brevity of the study, since SMA Type 3 doesn’t typically progress rapidly. Larger, well-powered studies may better define the role of amifampridine as adjunctive treatment to SMN-enhancing treatments. (Bonanno, S., et al. (2022).

The study, conducted at 326 treatment centers worldwide, compared the safety and efficacy of etrolizumab, in two dosage strengths, with placebo as both induction and maintenance therapy.READ MORE...The study, conducted from March 2015 through September 2021, enrolled patients ages 18 to 80 with moderate to severe active Crohn disease, as defined by a Crohn Disease Activity Index (CDAI) score between 220 and 480, mean daily stool frequency score greater than or equal to 6, or daily stool frequency score greater than or equal to 3 and mean daily abdominal pain score greater than or equal to 1, and presence of active inflammation on ileocolonoscopy. The patients also had intolerance to or inadequate or no response to treatment with corticosteroids, immunosuppressants, or anti-TNF therapy within the past 5 years.BERGAMOT consisted of three induction cohorts (a placebo-controlled, double-blind exploratory cohort; an active cohort without placebo control; and a placebo-controlled, double-blind pivotal cohort) and a maintenance cohort. This report discusses the findings of cohort 3, in which 385 patients were randomly assigned to placebo (n = 97), 105 mg etrolizumab subcutaneously every 4 weeks (n = 143), or 210 mg etrolizumab subcutaneously every 4 weeks (n = 145). At week 14 of induction therapy, patients from all three cohorts who had a response to etrolizumab as measured by CDAI-70 were rerandomized to receive 105 mg etrolizumab or placebo as maintenance every 4 weeks for 52 weeks. As a result, 434 patients took part in the maintenance phase, 217 in the placebo arm, and 217 in the etrolizumab arm.The researchers determined the proportion of patients who entered clinical remission, defined as mean daily stool frequency less than or equal to 3 and mean daily abdominal pain less than or equal to 1, with no worsening, and the proportion who demonstrated endoscopic improvement, as shown by greater than or equal to 50% reduction in Simple Endoscopic Score for Crohn’s Disease (SES-CD). At week 14, 48 patients (33%) in the 210-mg induction group versus 28 patients (29%) in the placebo group were in clinical remission (adjusted treatment difference, 3.8%). Endoscopic improvement was seen in 40 patients (27%) in the 210-mg induction group vs. 21 patients (22%) in the placebo group (adjusted treatment difference, 5.8%). At week 66 of maintenance treatment, significantly higher proportions of patients receiving etrolizumab than those receiving placebo were in clinical remission: 76 patients (35%) in the etrolizumab maintenance group versus 52 patients (24%) on placebo (adjusted treatment difference, 11.3%). Significantly higher proportions of patients in the etrolizumab arm showed endoscopic improvement: 51 patients (24%) vs. 26 patients (12%) in the placebo arm (adjusted treatment difference, 11.5%).These findings demonstrate a significantly higher incidence of clinical remission and endoscopic improvement in patients with moderate to severe Crohn disease during the maintenance phase of treatment with etrolizumab, but not during induction.

The TEAM-VTE study, an international multicenter prospective cohort study in patients of reproductive age (18 to 50) diagnosed with acute VTE, was conducted at 12 hospitals across 8 European countries between August 2018 and September 2021. The study, published in the journal Blood, aimed to quantify the burden of AUB and to identify unmet clinical needs in patients receiving anticoagulant therapy.READ MORE...From August 2018 to March 2021, 98 patients with confirmed symptomatic first or recurrent VTE and active menstrual cycles, with a mean age of 34, were enrolled shortly after diagnosis of VTE (before the first day of the next menstrual cycle after VTE diagnosis or within 1 month of diagnosis) and were followed until discontinuation of anticoagulant treatment or 6 months, whichever came first. If AUB was discovered, a diagnostic workup was performed to rule out other causes of the bleeding. The patients were followed using various measures:· Menstrual blood loss for the last menstrual cycle before VTE and then for each cycle in the 3 to 6 months of follow-up was measured by pictorial blood loss assessment charts (PBAC), a validated self-reporting tool.· AUB-related QOL was assessed at baseline and the end of follow-up using the Menstrual Bleeding Questionnaire (MBQ); these were available for 74 women.Patients were followed for recurrence of symptomatic VTE, any bleeding event other than AUB, and all-cause mortality, and were managed according to accepted guidelines and local preference. The researchers noted which anticoagulant was administered to treat the VTE in these patients; 78 were treated with oral direct factor Xa inhibitors (rivaroxaban, apixaban, edoxaban), 13 with vitamin K antagonists (warfarin) or low-molecular-weight heparins, and 7 with the direct thrombin inhibitor dabigatran.Overall, AUB as defined by one of three accepted measures (PBAC score greater than 100, PBAC score greater than 150, or self-report) occurred in 66% of patients at any time during the follow-up period; for 90% of them, this occurred within the first 2 months after VTE diagnosis. Among women without AUB before VTE based on retrospective PBAC scores (assessing blood loss during the last menstrual cycle before VTE diagnosis), new-onset AUB occurred in 60% (37% of the overall population of study) in those with retrospective PBAC less than or equal to 100, and in 63% (43% of the overall population) in those with retrospective PBAC less than or equal to 150.The median PBAC score increased during the first menstrual cycle compared with the retrospective PBAC (median PBAC before VTE was 35 and for first menstrual cycle was 95). After the first menstrual cycle, the amount of blood loss decreased gradually, followed by median PBAC scores that remained stable in the 2nd through 6th cycles at about twice the retrospective PBAC score. The observational design of the study and the low number of patients exposed to the different anticoagulants prevent drawing any definitive conclusions about differences among the oral anticoagulants; however, patients treated with dabigatran showed no increase in blood loss during the first cycle, in contrast to patients treated with either oral direct factor Xa inhibitors, vitamin K antagonists, or low-molecular-weight heparin.The overall QOL decreased significantly over time, with a mean increase in MBQ score of 5.1 points between baseline and cessation of anticoagulation or 6-month follow-up. On analysis, the decrease in QOL was observed only among those who had new-onset AUB, with mean difference in MBQ score of +9.2 points for those with new-onset AUB versus those without AUB and of +9.3 points for those with new-onset AUB versus those who had experienced AUB before VTE.These findings support the proposed association of incident AUB with anticoagulation and highlight the critical need to include assessment of AUB in daily practice. It should increase awareness and should lead to development of evidence-based strategies to routinely and adequately prevent and treat incident AUB in this setting. (de Jong, C. M. M., et al. (2022).

Centanafadine in Adults with Attention Deficit Hyperactivity DisorderAttention deficit hyperactivity disorder (ADHD) likely results from dysregulation of the complex interplay of adrenergic and dopaminergic neurotransmission, resulting in deficits in executive function, reward processing, and attention. Centanafadine, a stimulant with nonstimulant characteristics that acts by inhibiting reuptake of norepinephrine, dopamine, and serotonin, is being investigated for use in adults with ADHD.READ MORE...A report in the Journal of Clinical Psychopharmacology describes the first large-scale studies to demonstrate the safety and efficacy of centanafadine in adults with ADHD. The two phase 3 randomized, double-blind, placebo-controlled, parallel-group studies were conducted from January 2019 through early 2020 in 45 clinical sites in the United States. To limit placebo effect, both studies were designed with a single-blind placebo run-in period, in which subjects who experienced an improvement in symptoms didn’t move on to randomization. The studies then randomized subjects to receive 200 mg/day of centanafadine sustained-release tablets (n = 149 study 1, 145 study 2); 400 mg/day of centanafadine sustained-release tablets (n = 149 study 1, 143 study 2); or placebo (n = 148 study 1, 142 study 2). Patients in both studies had moderate to severe ADHD at baseline (mean Adult ADHD Investigator Symptom Rating Scale [AISRS] total score, 38.7).Investigators determined change from baseline at day 42 in AISRS total score and in the Clinical Global Impression-Severity of Illness Scale (CGI-S). At day 42, statistically significant improvement in AISRS total score was achieved for both dosages compared with placebo in both studies. The AISRS total scores at day 42 were reduced by 25.5% in study 1 and 32.2% in study 2 for the 200-mg dose, by 24.6% in study 1 and 32.2% in study 2 for the 400-mg dose, compared to 17.7% in study 1 and 21.4% in study 2 for placebo. The differences in AISRS for centanafadine vs. placebo were as follows:• Study 1: -3.16 for 200 mg, -2.74 for 400 mg• Study 2: -4.01 for 200 mg, -4.42 for 400 mgThese differences were seen as early as day 28 and persisted throughout the study. Both dosages also produced statistically significant improvements in CGI-S score vs. placebo at day 42, as follows:• Study 1: -0.27 for 200 mg, -0.28 for 400 mg• Study 2: -0.33 for 200 mg, -0.28 for 400 mgThe overall rate of treatment-emergent adverse events was low, but there was a small increase noted with increases in centanafadine dose. The most common were headache and decreased appetite, which were considered mild or moderate.These trials were affected by the COVID-19 pandemic; study protocols had to be altered in late March 2020. As of March 23, study 1 had met its targets, so subjects still in treatment were withdrawn and continued to the safety follow-up phase, but study 2 had not yet met its completed-subject targets. All subjects who had not been randomized yet had treatment discontinued, and those who had been randomized continued to study completion, unless they tested positive for COVID. As a result, 348 subjects completed study 1 and 336 completed study 2. The most reported reason for discontinuation in study 1 was protocol deviation (5.6%), followed by adverse effects (4.1%) and withdrawal by subject (3.2%); in study 2 it was “other, not COVID-related” (6.6%), followed by withdrawal by subject (4.5%) and adverse effects (3.0%). Nine subjects in each study withdrew for reasons related to COVID-19.But despite these restrictions, the results still reached statistical significance. Future studies should determine long-term safety and should compare centanafadine to other available therapies for adults with ADHS. (Lenard, A., et al. (2022).

Economically disadvantaged Black American and Hispanic American children are among those with the highest risk of morbidity and mortality associated with asthma, but there is scant data available on effective strategies in this vulnerable population. A new study demonstrates that adjunctive treatment with the humanized monoclonal antibody mepolizumab significantly reduced the number of asthma exacerbations in urban Black American and Hispanic American children. The study, MUPPITS-2 (Mechanisms Underlying Asthma Exacerbations Prevented and Persistent with Immune-based Therapy), was published in The Lancet.READ MORE...Between November 2017 and mid-March 2020, 290 children and adolescents were enrolled in the double-blind, placebo-controlled study, which was conducted at nine urban medical centers in the United States. The researchers enrolled children and adolescents ages 6 to 17 years who lived in socioeconomically disadvantaged neighborhoods and had exacerbation-prone asthma (that is, at least two exacerbations in the prior year) and blood eosinophil count of at least 150 cells/microliter. Median age of participants was 10 years; 55% were boys; approximately 70% were Black American and approximately 25% were Hispanic American. Median household income was $1,250 or less/month in 37% to 40% of participants, and between $1,251 and $2,500/month in 32% to 37% of participants. The children were randomly assigned to mepolizumab (n = 146) or to placebo (n = 144) injections once every 4 weeks for 52 weeks. The dosage of mepolizumab varied by age: 40 mg was given to those ages 6 to 11 years, and 100 mg was given to those ages 12 to 17 years. All participants also continued to receive guideline-based care for their asthma. The researchers aimed to determine whether adding mepolizumab to guideline-based care reduced the number of asthma exacerbations treated with systemic steroids during the 52 weeks of therapy.The average number of asthma exacerbations requiring treatment with systemic steroids fell significantly during the 52 weeks of the study. Among children and adolescents treated with mepolizumab, the number of exacerbations was 0.96; with placebo, it was 1.30. Relative decrease in these patients was 27%. Blood eosinophil levels were markedly reduced in patients who received mepolizumab, from a mean of more than 400 cells/microliter at baseline to less than 200 cells/microliter by week 8. These levels remained over 400 cells/microliter in placebo-treated children. Time to first asthma exacerbation wasn’t significantly different between the two groups, and no differences were shown in other asthma outcomes (lung function, change in disease severity). On patient global assessment, 84% of participants treated with mepolizumab and 89% of those treated with placebo self-reported clinically moderate or significant disease improvements. Study clinicians completed that same assessment and found improvement among 66% treated with mepolizumab and 71% treated with placebo.Researchers concluded that these findings highlighted the importance of evaluating treatment response in urban Black American and Hispanic American children, populations that are typically underrepresented in clinical trials.

A review of current literature published in ESC Heart Failure, a journal from the European Society of Cardiology, provides evidence that obesity can potentiate CV risks—especially of venous thromboembolism (VTE)—in women of reproductive age taking combination oral contraceptives (COCs).READ MORE...The review examined the latest evidence and ongoing research on the CV impact of both obesity and contraceptive use, with a specific focus on clinical implications. An Italian review article cited a large population-based study showing that a body mass index (BMI) greater than 25 but less than 30 was associated with a 1.7-fold increased risk of VTE and a BMI above 30 was associated with a 2.4-fold increased risk. The study showed that when these subjects took COCs, risks increased to 12-fold in the group with BMI between 25 and 30 and to 24-fold in the group with BMI over 30 when compared to women who are nonobese not taking COCs. Another study was a meta-analysis that determined odds ratios (ORs) of VTE in women using COCs and showed that OR increased with BMI. When compared with COC users with BMI between 20 and 24.9, the odds of VTE in women using COC with BMI between 30 and 34.9 was 1.8 and in those with BMI of 35 or greater was 3.1. Another study showed that obesity has a greater impact on CV risk in women younger than age 40, the population that uses contraception; the risk of thrombosis in these individuals is 6.1 times higher than the risk in women who are nonobese. In addition, risk of drug-induced thrombosis can be dependent on the duration of drug therapy, a relevant issue with COCs, since users typically take them long-term.These findings should spur conversations between clinicians and young women early in their reproductive years to enable them to understand the risks and to make lifestyle and contraceptive choices that can minimize these risks. Women with a BMI over 30 taking COCs should be viewed as an at-risk population and should be advised to avoid other CV risk factors as primary prevention. In addition, clinicians should prioritize long-acting reversible methods of contraceptives such as intrauterine devices and subdermal implants, both for safety and effectiveness, in these patients.

Sickle cell anemia is the most severe form of sickle cell disease, a disorder that results in misshapen, sticky red blood cells that break down easily, blocking blood flow and therefore resulting in impaired oxygenation of body tissues. The Centers for Disease Control and Prevention (CDC), which published this report, notes two health care measures are important in preventing complications in children with sickle cell anemia:READ MORE...Transcranial Doppler (TCD) ultrasound screening, which identifies children at risk for strokeHydroxyurea, a myelosuppressive agent, which reduces the occurrence of several complications of sickle cell anemia, including severe acute pain episodes and acute chest syndrome, which can result in lung injury and trouble breathingSickle cell anemia is a leading cause of stroke, but data showed that fewer than half of children with the disorder received the recommended stroke screening in 2019. The CDC’s analysis of 2019 Medicaid data showed that only 38% of children with sickle cell anemia ages 10 to 16 and 47% of those ages 2 to 9 had undergone TCD ultrasound screening. In addition, only 2 in 5 children ages 2 to 9 received hydroxyurea, the recommended treatment. The CDC study showed that in 2019, 53% of those ages 10 to 16 and 38% of those ages 2 to 9 were prescribed hydroxyurea. Stroke screening and hydroxyurea use were highest among children with high levels of health care use and those with prior complications.These results reflect the barriers to care of sickle cell patients, including structural racism. Patients lack access to providers with expertise in treating the disease and report having their symptoms dismissed or being stigmatized when they do engage with the health care system. In addition, both family members and providers hesitate to make use of hydroxyurea due to fear of potential side effects and uncertainty about its effectiveness.The CDC recommends that clinicians take steps to ensure that children with sickle cell anemia receive this important screening and this potentially lifesaving treatment. Among their recommendations:Increase TCD stroke screening by educating patients and families about the risk of stroke and the screening, identifying barriers to access (transportation, finances) and taking steps to alleviate them.Make stroke screening part of a single comprehensive visit when possible, and track TCD ultrasound screenings and follow-up in electronic health records.Encourage the patient and family to discuss with a health care provider the results of the TCD ultrasound screening and the next steps to take if the results indicate a greater risk of stroke.Become familiar with the guidelines on prescribing hydroxyurea and with studies showing the safety of the drug in these patients.To encourage adherence and follow-up, address barriers to patient access and incorporate reminders into the electronic health record.Educate the patient and family about hydroxyurea and the pros and cons of adherence to treatment protocol, and develop tools to help patients take hydroxyurea as directed.(CDC.

Evening Dosing of Antihypertensive Not Superior to Morning DosingA randomized UK trial in more than 21,000 patients with hypertension has challenged the long-standing belief that evening doses of antihypertensive medications lead to better outcomes. Results of the trial TIME (Treatment In Morning vs. Evening), a large, prospective, randomized trial that tested whether evening doses of antihypertensives improved major CV outcomes compared with morning dosing, were presented at the European Society of Cardiology Congress in Barcelona.READ MORE...Adults taking antihypertensive medications in the UK who had a valid e-mail address were recruited and followed for more than 5 years. After signing up on the trial website, participants were randomized, 10,503 to evening dosing and 10,601 to morning dosing. Average age of patients was 65; 58% were men and 98% were white. Information on outcomes was obtained from e-mail contact with participants and through record linkages to national databases. Further data was gathered from family doctors and hospitals in the UK and was adjudicated by a blinded committee.The composite endpoint for the study was hospitalization for nonfatal MI, nonfatal stroke, or vascular death. This occurred at similar frequencies regardless of the time of medication administration: 362 participants (3.4%) in the evening dosing group and 390 participants (3.7%) in the morning dosing group experienced these outcomes, for an unadjusted hazard ratio (HR) of 0.95. Other outcomes also showed that neither time of antihypertensive dosing was superior to the other. These outcomes include:Nonfatal stroke: HR, 0.93Nonfatal MI: HR, 0.92CV death: HR, 1.1All-cause mortality: HR, 1.04During the presentation, researchers concluded that patients can take their regular antihypertensive medications at a time of day that is convenient and works for them.

On May 17, 2022, the FDA authorized a booster dose of the Pfizer-BioNTech COVID-19 vaccine under Emergency Use Authorization for children ages 5 to 11 years, to be given 5 months after receipt of the second primary series dose. Approximately 650,000 booster doses were administered to individuals in this age group in the first 10 weeks of rollout (May 17 to July 31).READ MORE...Safety data were obtained from v-safe, a voluntary smartphone-based safety surveillance system established to monitor adverse events after COVID-19 vaccination, and from VAERS (Vaccine Adverse Event Reporting System), a national passive vaccine safety surveillance system comanaged by the CDC and FDA. Through v-safe, health surveys are sent daily to registrants during the first week after vaccine administration, with questions about potential local injection-site reactions and systemic reactions as well as health inputs. If parents indicate on the survey that they sought medical care for their child after vaccination, the CDC’s v-safe call center contacts them and encourages completion of a VAERS report. VAERS was developed to monitor adverse events after vaccination; it accepts reports from health care providers, vaccine manufacturers, and members of the public. Serious events that are included in the report include hospitalization, life-threatening illness, permanent disability, congenital anomalies/birth defects, or death.During those first 10 weeks, approximately 657,302 U.S. children received a third (booster) dose of the Pfizer-BioNTech vaccine; 3,249 reports were made to v-safe for children in this age group. Both local injection-site reactions (n = 2,224) and systemic reactions (n = 1,483) were reported; the prevalence of both was similar to that seen after the second dose of the vaccine:Local reactions: 68.5% booster, 68.0% second doseSystemic reactions: 45.6% booster, 45.8% second doseThe most frequently reported adverse events were injection-site pain (n = 2,166), fatigue (n = 938), and headache (n = 647); most were mild and were most frequently reported the day after vaccination. In the week after receiving the booster, 225 enrolled children were unable to attend school, and 392 were unable to complete daily activities. The inability to attend school was reported less frequently than after the second dose (6.9% vs. 10.0%), but inability to complete daily activities was reported more frequently (12.1% vs. 7.5%).VAERS received 581 reports of adverse events after receipt of the booster by children ages 5 to 11; 578 (99.5%) of these reports were considered nonserious. The most commonly reported events (71.1%) were vaccine administration errors (such as preparation errors, incorrect dose, and inappropriate age). Local and systemic reactions were common among the VAERS reports, but no reports of myocarditis or death were received. Only three serious reports were made to VAERS: new-onset diabetes 10 days after vaccination, facial swelling 3 days after vaccination, and pain, fatigue, and malaise 5 days after vaccination.These findings may change somewhat over time, as safety monitoring continues, more school-age children receive boosters, and as vaccine providers gain additional experience with pediatric doses of COVID-19 vaccines. Continued education of vaccine providers might reduce the errors reported to VAERS. (Hause, A. M., et al. (2022).

Currently, if a patient’s disease progresses on initial therapy with the folic acid antagonist methotrexate, combination therapy with the tumor necrosis inhibitor adalimumab plus methotrexate is administered. Olokizumab is a monoclonal antibody that targets IL-6, which is known to play a role in the inflammatory process and in the progression of joint damage in RA.READ MORE...CREDO2 (Clinical Rheumatoid Arthritis Development of Olokizumab) was a Phase III, double-blind, randomized, placebo- and active-controlled, international trial conducted from May 2016 through November 2019 at 209 sites worldwide. Results of the multicenter study, published in the New England Journal of Medicine, compared treatment with olokizumab plus methotrexate to placebo and to the gold standard, adalimumab plus methotrexate, testing for superiority to placebo and for noninferiority to adalimumab.The study randomly assigned patients with RA and inadequate response to initial methotrexate treatment to receive olokizumab 64 mg every 2 weeks (n = 464), olokizumab 64 mg every 4 weeks (n = 479), adalimumab 40 mg every 2 weeks (n = 462), or placebo (n = 243). All patients continued receiving methotrexate. Patients were followed to determine if they met the criteria for an American College of Rheumatology 20 (ACR20) response by week 12. Such a response entails at least 20% fewer tender or swollen joints and an improvement of at least 20% in 3 of 5 treatment domains:Patient’s global assessment of disease activityPatient’s assessment of painProvider’s global assessment of disease activityPatient function according to score on Health Assessment Question-Disability IndexC-reactive protein level.Results demonstrated that, in patients with RA who were receiving maintenance methotrexate, olokizumab was superior to placebo and noninferior to adalimumab in producing ACR20 response at week 12. The proportion of patients who reached ACR20 response at 12 weeks was 44.4% with placebo, 70.3% with olokizumab every 2 weeks, 71.4% with olokizumab every 4 weeks, and 66.9% with adalimumab. Both dosages of olokizumab were considered noninferior to adalimumab on this measure.The percentage of patients with a Disease Activity Score 28 of less than 3.2 (a measure of acute inflammation) at week 12 was 12.8% of those receiving placebo, 45.3% of those receiving olokizumab every 2 weeks, 45.7% of those receiving olokizumab every 4 weeks, and 38.3% of those receiving adalimumab. The percentage of patients who achieved remission, as assessed by Clinical Disease Activity Index score of 2.8 or less at week 24, was 41.4% with placebo, 11.2% with olokizumab every 2 weeks, 12.1% with olokizumab every 4 weeks, and 13.0% with adalimumab. Adverse events occurred in approximately 70% of patients and were most commonly infections that were mild to moderate in severity.These results offer another option for treatment for patients with RA, up to 25% of whom don’t respond well to current treatment options. Larger and longer trials are needed to further elucidate the safety and efficacy of olokizumab in RA. (Smolen, J. S., et al. (2022).

No significant harm was associated with statin use in these studies, suggesting a significant overall benefit to their use as primary prevention.Based on this analysis, USPSTF makes the following clinical recommendations:Clinicians should prescribe statins as preventive for CVD in adults ages 40 to 75 who have at least one risk factor for CVD and a 10-year CVD event risk of 10% or greater; the analysis showed with moderate certainty that use of statins in this population had at least a moderate net benefit.Clinicians can selectively offer statins to those ages 40 to 75 with at least one CVD risk factor and a 10-year CVD event risk between 7.5% and 10%, taking the patient’s values and preference into account, as well as the presence of factors not included in the original risk assessment; the analysis showed with moderate certainty that use of statins in this population had a smaller net benefit.Evidence is insufficient to determine how beneficial it would be to prescribe statins as primary prevention for CVD events and mortality in adults age 76 or older with no history of CVD. Such use would be at the discretion of the clinician, taking other factors into consideration.The analysis also demonstrates directions for research, including improving the accuracy of CVD risk prediction in all racial, ethnic, and socioeconomic groups, gaining a clearer picture of the benefits and harms of statins as primary prevention in older adults, and determining the efficacy and safety of long-term statin use in younger adults, as well as examining the effects of early versus delayed initiation of statin therapy for primary prevention of CVD disease.

Need for Access to Contraception Still Unmet for Many WomenThe Family Planning 2020 Initiative set a goal of increasing the number of women using modern contraceptives by 120 million in priority countries. A new report in The Lancet estimates that this number increased by 69 million in these countries, which would fall 51 million short of that goal. In the study, part of the systematic analysis for the Global Burden of Disease Study 2019, higher rates of contraceptive coverage were linked with the availability of a diverse range of contraceptive choices. This study elucidates the major increases in contraceptive use and the reductions in unmet need that have occurred since 1980.READ MORE...Researchers examined 1,162 population-based surveys of contraceptive use by women of reproductive age (ages 15 to 49) who self-reported current use of contraceptives for family planning. Using regression analysis, they determined estimates of the contraceptive prevalence rate (CPR) and modern CPR (mCPR), whether the demand for contraception was satisfied, and the contraceptive method mix, and examined them in both partnered and unpartnered women in five age groups.Between 1970 and 2019, increases were observed in use of all contraceptives (CPR), increasing by 18.7 percentage points, and that of mCPR, by 20.1 percentage points. The demand satisfied increased by 24.3 percentage points. In 2019, the average CPR was 51.9%, average of mCPR was 47.7%, and demand satisfied was 79.1%, although there were considerable differences geographically.Women ages 15 to 24 accounted for 16.0% of total need but 26.5% of global unmet need. The lowest rate of demand satisfied was found in women ages 15 to 19 (64.8%), followed by those ages 20 to 24 (71.9%); 43.2 million women ages 15 to 24 had unmet needs for contraception in 2019. These lower rates of satisfied demand in young women are cause for concern because of the effects both on the women themselves and society in general. Use of contraception is associated with reductions in maternal and neonatal mortality due to the avoidance of unintended and adolescent pregnancies, and access to contraceptives supports pursuit of education and economic opportunities. To address these disparities, family planning programs must determine the accessibility and acceptance of existing methods in use by other women among this younger age group.The methods women used to meet their contraception needs differed by marital status, age, and region. Compared with partnered women of all ages, unpartnered women more commonly used oral contraceptive pills and condoms; long-acting reversible methods (such as, IUDs, contraceptive implants, or injections) tended to be used most by women ages 20 to 49, and older women were more likely to use female sterilization.The absence of contraceptives tailored to the needs of younger women might be one explanation for the unmet need in that population; for example, if female sterilization is the method most often available, it’s unlikely to appeal to young women who haven’t had children yet. (Haakenstad, A., et al.

A retrospective case-control study published in JAMA Otolaryngology–Head and Neck Surgery attempted to determine whether that outpatient macrolide treatment was associated with pediatric sensorineural hearing loss. Past research has linked sensorineural hearing loss in adults to prior use of high-dose or IV macrolide treatment, but it hasn’t been studied in children.READ MORE...Using data from TRICARE, the health insurance system for U.S. uniformed service members and their families, the study analyzed 875 matched pairs of children, adolescents, and young adults with and without sensorineural hearing loss from records of outpatient encounters from October 2009 to September 2014. They were matched by age, sex, and time elapsed since the date of antibiotic prescription. Mean age was 5.7 years; patients were 62% male, and 66% non-Hispanic white. Multivariate logistic regression was used to compare the risk of prior macrolide exposure with penicillin exposure, adjusted for other risk factors and potential confounders.They found that compared with peers without hearing loss, pediatric patients with sensorineural hearing loss were more likely to have received a prescription for a macrolide antibiotic compared to one for penicillin (adjusted odds ratio [aOR], 1.31). The odds were significantly higher when more than 180 days had elapsed between antibiotic exposure and the patient’s testing and diagnosis of hearing loss (aOR, 1.79).Currently, 56% of pediatric sensorineural hearing loss is considered idiopathic; this study suggests that macrolides warrant further study as potential risk factors. The results could also guide practice by encouraging early recognition of sudden hearing loss after macrolide use, given the success rate of prompt hyperbaric oxygen treatment for these patients. (Lopilato, J.

OPERA-II, a multicenter, open-label phase 2 extension study, examined the long-term safety and efficacy of one of these treatments, ontamalimab, a fully human IgG monoclonal antibody against mucosal addressin cell adhesion molecule-1.READ MORE...All patients in the study had completed 12 weeks of treatment in OPERA, a phase 2, double-blind, placebo-controlled trial that examined three dosage strengths of ontamalimab (22.5 mg, 75 mg, or 225 mg) and compared clinical response and remission in 265 patients with Crohn disease, or had had a clinical response to a 225-mg dose of ontamalimab in another study, TOSCA, a 12-week, open-label study in which ontamalimab was given to 39 patients with active Crohn disease who had previously received immunosuppressants. In OPERA, clinical response and remission were observed in greater proportions of patients in the treatment group than with placebo, although these differences hadn’t reached statistical significance, and in TOSCA, 80% of treated patients had a clinical response and 77% were in clinical remission at week 12.Conducted from July 2011 through July 2016 in 81 centers in 15 countries worldwide, OPERA-II examined safety (adverse events and serious adverse events) and efficacy (clinical remission and response rates at weeks 24 and 72, the rate of relapse and time to relapse, the proportions of patients with changes in dosage, and proportion who discontinued by week 16) outcomes in patients with moderate to severe Crohn with a history of failed immunosuppressant therapy. Participants received ontamalimab at 75 mg every 4 weeks for 72 weeks, and then were followed up every 4 weeks for 24 weeks. Dosage could be decreased to 22.5 mg for intolerance or adverse events or increased to 225 mg in patients with inadequate response.Overall, 149 of 268 patients completed the study; 74 patients discontinued during the study period and another 45 during follow-up. The most common event leading to discontinuation was disease flare, in 19.8% of patients; 2 patients died, no patients required dosage reductions, and 157 had dosage escalations. Median time to dosage escalation was 28 weeks. Of the 68 patients who required dosage escalation by week 8, 13 subsequently discontinued the study by week 16. During the treatment period, 249 patients reported a total of 1,550 adverse events, of which 385 were considered treatment related. During the follow-up period, 133 patients experienced a total of 461 adverse events, of which 42 were treatment related.Rates of clinical remission of Crohn disease, defined as a score on the Harvey Bradshaw index (HBI) less than or equal to 5, was 48.1% at baseline, 47.8% at the end of week 24 of follow-up, and 37.3% at week 72. Of the 128 patients who were not in remission at baseline, 84 achieved remission during the study, with a median time to remission of 16.9 weeks. Similar results were seen in response, as measured by decreases in HBI greater than or equal to 3 points; at baseline the response rate was 63.1%, at week 24 it was 54.5%, and by week 72 was 42.5%. Of the 99 patients who hadn’t demonstrated clinical response at baseline, 68 did so during the study, with a median time to response of 13.9 weeks. In those who received the higher, 225-mg dose, the proportion of those in remission remained relatively stable from week 12 (31.8%) to week 72 (32.2%). Relapse was defined as an increase greater than or equal to 3 points in HBI score from the lowest HBI score measured, with a total HBI score greater than or equal to 8.

Lidocaine Infusions Relieve Pain in Chronic MigrainePatients with a particularly refractory form of chronic migraine who received a multiday continuous lidocaine infusion as part of aggressive inpatient treatment reported significant improvement in pain immediately following the infusion, and almost half of those who responded reported sustained relief at 1 month. This retrospective cohort study, published in Regional Anesthesia and Pain Medicine, analyzed medical records of patients with chronic migraine (at least 15 headache days/month for at least 3 months, in which at least 8 days meet criteria for migraine) refractory to outpatient treatment. These patients are treated in hospital with infusions of NSAIDs, corticosteroids, and neuroleptics, hoping to break the cycle of pain.READ MORE...Researchers examined the medical records of 609 hospital admissions from April 2017 to April 2020 at the Jefferson Inpatient Headache Unit in Philadelphia. This comprised 537 unique patients; 72 admissions were repeat admissions. Mean number of days between hospitalization for repeat admissions was 215.2 days. The mean age of the patients was 46, and 81% were female; all met criteria for refractory chronic migraine. The patients received continuous lidocaine infusions, starting at 1 mg/min and titrated to a maximum of 4 mg/min based on daily plasma levels, pain response, and tolerability. The infusions were planned for 5 to 7 days, although length differed based on clinical factors; for example, hospitalization and the infusion could be extended if the patient reported that the pain was slowly but steadily improving. The patients were otherwise be discharged from the hospital if they reported being pain-free for from 12 to 24 hours, or had a pain level that the patient felt allowed improved function, or if they experienced minimal response to treatment by hospital day 5. Mean duration of treatment was 5.2 days.Patients recorded pain intensity using a self-report Numerical Rating Scale, from 0 (pain-free) to 10 (worst pain imaginable); researchers measured change in that self-reported headache pain from baseline to discharge. At baseline and at postdischarge office visits (25 to 65 days after discharge), patients were also asked the number of headache days they had experienced during the previous 28 days, as well as current worst daily pain and average daily pain.A decline in median pain ratings was seen with lidocaine infusion: from 7.0 at baseline to 1.0 at discharge. Nearly 88% of patients showed a reduction in pain ratings by at least 2 points during the hospitalization period. These patients were labeled acute responders; of the 535 acute responders with available postdischarge data, 43.2% showed sustained improvements. Average pain remained below baseline at the postdischarge visit, with a median score of 5.5, and the patients reported fewer headache days in the previous month compared to baseline: 22.5 days vs. 26.8 days.The high acute responder rate is an encouraging finding, providing evidence of rapid relief for these patients. The waning of the effect seen over follow-up reflects the challenges presented by refractory chronic migraine. These results should offer support for design and implementation of randomized, controlled studies of lidocaine infusions to allow increased use of this treatment. Clinicians meanwhile can use these study results in their communications with patients, describing the likelihood of relief and the expected duration of that relief. (Shukla, D.

A case-control study published in the New England Journal of Medicine assessed the effectiveness of full maternal vaccination (that is, two doses of an mRNA SARS-CoV2 vaccine) against hospitalization for COVID-19 in infants younger than age 6 months. Between July 2021 and March 2022, the study enrolled infants hospitalized for COVID-19 (case infants; n = 537) and matched them with hospitalized infants who didn’t have COVID-19 (control infants; n = 521) at 30 hospitals across 22 U.S. states. Median age of infants was 2 months; 19% of case infants and 24% of control infants had at least one underlying health condition. All case infants were identified with COVID-19 as the primary reason for their admission or with a clinical syndrome consistent with acute COVID-19 who then tested positive on a SARS-CoV2 PCR test; control infants were hospitalized for other reasons and tested negative on a PCR test. Researchers attempted to enroll a control infant for every case infant, with a date of hospital admission that was within 4 weeks of the admission date of the case infants.READ MORE...The overall effectiveness of maternal vaccination against COVID-associated hospitalization in their infants age 6 months and younger was 52%; its effectiveness against intensive care unit admission was 70%. Among case infants, 113 (21%) required intensive care treatment for COVID-19, including 64 (12%) who required mechanical ventilation or vasoactive infusions. Two infants died and two required ECMO treatment; none of these four infants was born to fully vaccinated mothers.The study examined appropriate timing of maternal vaccination to facilitate the greatest transfer of maternal antibodies. In this study, effectiveness at preventing hospitalization was 69% when vaccinated after 20 weeks of pregnancy and 38% when the last vaccination was given during the first 20 weeks of pregnancy. The researchers were also able to examine results during the period of the circulation of the delta and omicron variants of the virus. Of the 537 case infants, 181 were admitted during the delta circulation period and 356 during the omicron circulation period. The effectiveness of the maternal vaccination against COVID-19 hospitalization was 80% during the delta period and 38% during the omicron period.These data support the safety of COVID-19 vaccination during pregnancy. The CDC recommends vaccination, including boosters, for pregnant people. Despite the known benefits and safety of the mRNA vaccine, vaccination rates during pregnancy still lag: only 71% of pregnant people in the United States were fully vaccinated, with an even lower rate among non-Hispanic Black people (58%).

A review and meta-analysis published in Mayo Clinic Proceedings offers evidence that “newer” P2Y12 receptor inhibitors should be preferred when treating this high-risk population.READ MORE...Current treatment of acute MI complicated by cardiac arrest or cardiogenic shock includes percutaneous coronary intervention followed by use of dual antiplatelet therapy with aspirin and a P2Y12 receptor inhibitor. Clopidogrel, the first P2Y12 inhibitor on the market, has been the standard of care; this study examined results of trials that compared outcomes with other P2Y12 inhibitors ticagrelor and prasugrel vs. clopidogrel.Because the large sample sizes seen in other studies of MI are not possible for these conditions, the review identified only eight studies, seven of them cohort studies. The studies comprised 1100 patients; 695 patients (63.2%) received clopidogrel and 405 patients (36.8%) received the newer P2Y12 inhibitors ticagrelor or prasugrel. They compared outcomes: early mortality, either in-hospital or 30-day all-cause mortality; 1-year, all-cause mortality; and the incidence of major bleeding and stent thrombosis.The “newer” P2Y12 cohort (prasugrel and ticagrelor) had lower rates of early mortality (odds ratio [OR], 0.60) and of 1-year mortality (OR, 0.51). The analysis did not find a significant difference in major bleeding (OR, 1.21) or in stent thrombosis (OR, 2.01) with use of ticagrelor or prasugrel, although there were numerically more bleeding events with the “newer” drugs.The study is limited by the retrospective, observational character of most of the studies involved; there is the risk that selection bias comes into play, as clinicians determine that certain patients would benefit from the more potent newer P2Y12 receptor inhibitors. In addition, it would be valuable to design a study that examined these complications separately, recognizing that cardiac arrest and cardiogenic shock have different effects on, for example, perfusion of other organs.

Mepolizumab a Good Choice in Chronic Rhinosinusitis with Comorbid AsthmaResults of the phase III SYNAPSE study demonstrated the effectiveness of mepolizumab in reducing nasal polyp size and nasal obstruction in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Mepolizumab is an MAb that prevents interleukin-5 from binding to its receptors on eosinophils, thus selectively inhibiting eosinophilic inflammation. The burden of disease in CRSwNP is greatest among those with comorbid asthma or aspirin-exacerbated respiratory disease (AERD) and in patients with eosinophilic infiltration. The researchers conducted a subgroup analysis targeting those patients that suggests that mepolizumab should be the treatment choice in CRSwNP in patients with comorbid asthma or AERD.READ MORE...SYNAPSE was a randomized, double-blind, 52-week study in patients with severe bilateral CRSwNP eligible for surgery despite intranasal corticosteroid treatment. Enrolled patients received subcutaneous mepolizumab 100 mg or placebo every 4 weeks plus standard of care (daily mometasone furoate nasal spray, saline nasal irrigations, and short courses of steroids or antibiotics, as needed) for 52 weeks. The patients had recurrent bilateral nasal polyps. The study reported the proportion of patients with greater than or equal to 1-point increase in total endoscopic nasal polyp score at week 52 and greater than or equal to 3-point improvement in nasal obstruction visual analog (VAS) score by weeks 49 to 52. Endoscopic nasal polyp score ranges from 0 (no polyps) to 4 (large polyps causing complete obstruction of inferior meatus) for each nostril, for a highest possible total score of 8. The nasal obstruction VAS score ranges from 0 to 10. This subgroup analysis included 407 patients; 289 had comorbid asthma, 108 had comorbid AERD, 371 had blood eosinophil cell (BEC) counts greater than or equal to 150 cells/f mm3, and 278 had BEC counts greater than or equal to 300 cells/f mm3.In the intent-to-treat population, more patients who received mepolizumab had greater than or equal to 1-point improvement from baseline in endoscopic nasal polyp score—50.5% of patients vs. 28.4% in the placebo group. The proportions of patients with greater than or equal to 1-point improvement in endoscopic nasal polyp score was higher across the various subgroups with mepolizumab vs. placebo:· Comorbid asthma: 52.9% vs. 29.5%· Comorbid AERD: 51.1% vs. 20.6%· BEC count greater than or equal to 150 cells/f mm3: 49.5% vs. 28.1%· BEC count greater than or equal to 300 cells/f mm3: 50.4% vs. 28.1%The proportion of patients who had a greater than or equal to 3-point improvement in nasal obstruction VAS score also differed greatly across these subgroups:· Comorbid asthma: 60.0% vs. 34.9%· Comorbid AERD: 64.4% vs. 30.2%· BEC count greater than or equal to 150 cells/f mm3: 59.1% vs. 34.1%· BEC count greater than or equal to 300 cells/f mm3: 59.0% vs. 32.4%Among the other findings is that patients receiving mepolizumab had a lower risk of surgery than those receiving placebo. This reduction was greater in patients without asthma than those with asthma but was similar irrespective of the presence of AERD. This benefit may be an important consideration for patients who express concern over the risks associated with surgery. (Bachert, C., et al. (2022).

However, research into treatments to mitigate the effects of the virus after infection are ongoing. In December 2021 two oral antiviral treatments were made available under an Emergency Use Authorization (EUA): ritonavir-boosted nirmatrelvir and molnupiravir.READ MORE...The Centers for Disease Control and Prevention has issued a health advisory with updates on the availability of and use of these treatments for mild to moderate COVID-19. When theseagents were first made available, ensuring adequate supplies to keep up with demand was challenging due to the rapid increase in omicron variant cases of COVID-19. These treatments are growing in importance as that highly transmissible variant continues as the predominant strain, with new subvariants emerging, and as mitigation strategies such as masking and social distancing are being phased out. The FDA has ensured that oral antivirals are widely available and can be accessed with a provider prescription at pharmacies and at Test-to-Treat locations.Both ritonavir-boosted nirmatrelvir and molnupiravir work best early in the course of illness before SARS-CoV2 can have a chance to replicate and do damage. They are authorized for use within 5 days of symptom onset in nonhospitalized patients who have tested positive for SARS-CoV2 and are at high risk. High-risk patients include those over age 65 or those older than age 12 with an underlying condition that increases the risk of severe outcomes of COVID-19, such as cancer, heart disease, diabetes, and obesity. The preferred therapies are the oral antiviral ritonavir-boosted nirmatrelvir and the infusion remdesivir. The alternatives, molnupiravir and the monoclonal antibody bebtelovimab (available under EUA since February 2022) are to be used only when the preferred treatments are unavailable, not feasible, or not appropriate. Ritonavir-boosted nirmatrelvir produced an 89% reduction in the risk of hospitalization and death; molnupiravir is less efficacious, producing a 30% reduction in risk. There are numerous considerations that come into play when deciding on which oral antiviral to use. Ritonavir-boosted nirmatrelvir should be avoided by those with severe kidney or liver disease; in addition, because ritonavir acts to boost levels of nirmatrelvir by slowing down hepatic metabolism of the other drug through inhibition of CYP3A4, its use should be avoided with other drugs highly dependent on CYP3A enzymes for clearance. Its use should also be avoided with use of CYP3A inducers, which can result in low levels of ritonavir and therefore loss of virologic response. Molnupiravir use should be avoided in those who are, or are attempting to become, pregnant and in those under age 18; men with sexual contact with women of childbearing age should use a reliable method of contraception during molnupiravir treatment and for 3 months afterward.In the battle against the pandemic, health care providers and their patients should be doing everything they can to avoid COVID-19 disease and disease progression in patients with risk factors: vaccinations, testing, isolation when positive, and these antiviral treatments. Providers should educate their patients at high risk not to overlook mild cases and to remember that accurate testing remains key to COVID-19 prevention. (Petty, L. A., & Malani, P. N.

These practices include polypharmacy (the use of five or more prescription drugs) and the use of drugs with sedative or anticholinergic properties, including antipsychotics, benzodiazepines, and antiparkinsonian drugs. These prescribing practices have been previously shown to be associated with physical frailty among older adults.READ MORE...The researchers for the University of Tsukuba conducted a population-based, case-control study, the study cohort nested within a cohort of older adults in a Japanese city. Using combined medical claims and long-term care (LTC) needs certification database, researchers identified 2,123 individuals who received a first LTC needs certification and matched them to 40,295 controls (accounting for 89% of the over-65 population) based on age, sex, residence, and the observation period. In Japan, people age 65 and older with a functional disability are eligible for LTC services; an LTC needs certification is needed to access these services, so the researchers were able to use it as a proxy for disability.The study demonstrated a dose-response relationship between both polypharmacy and the use of drugs with sedative or anticholinergic properties with the risk for LTC needs certification. Adjusted odds ratios (OR) of this outcome were as follows:· Polypharmacy (5 to 9 prescription drugs): OR, 1.32· Hyperpolypharmacy (greater than or equal to 10 prescription drugs): OR, 1.87· Cumulative doses of drugs with sedative or anticholinergic properties, in terms of defined daily dose:o defined daily dose 1–364: OR, 1.07o defined daily dose 365–729: OR, 1.25o defined daily dose greater than 730: OR, 1.33Further study should examine whether adjusting prescribing patterns in these patients could reduce the risk of LTC needs certification in older adults and reduce the LTC burden for the public.

FIREFISH is a phase II/III, 2-part, multicenter trial that examined the long-term efficacy and safety of risdiplam in infants with symptomatic Type 1 spinal muscular atrophy (SMA). SMA is a group of severe, progressive neuromuscular diseases that is the leading cause of infant mortality. It’s caused by a mutation of the SMN1 gene that leads to a deficiency of the SMN protein, resulting in cellular imbalance in motor neurons that in turn causes the motor neuron endplates to not properly connect to muscle and leads to death of the motor neurons. Without treatment, depending on the type of SMA, the patients can lose physical strength; and the ability to walk, eat, or breathe can be significantly diminished or lost. Untreated infants with type 1 SMA typically don’t survive past age 2. Risdiplam is a survival motor neuron 2 splicing modifier that allows production of full-length SMN protein and thereby can affect the progression of SAM.READ MORE...The original study evaluated efficacy and safety in infants ages 1 to 7 months at the time of trial enrollment. Part 1 of the trial was a dose-finding study; in part 2, the patients received liquid risdiplam orally or via feeding tube once daily. After 24 months, the trial entered a 3-year open-extension phase. At 36 months after trial enrollment, 91% (n = 58) of children treated with risdiplam were alive. The marker chosen to demonstrate efficacy was the percentage of children able to sit without support for 5 seconds, as assessed by the Bayley Scale of Infant Development at month 12. Without treatment, infants with type 1 SMA are never able to sit without support. At this 36-month follow-up, among the 48 children who could be assessed, 32 maintained that ability and 4 gained it between months 24 and 36, and no child who had gained the ability to sit without support for 5 seconds lost that ability. Further, 20 children maintained and 15 gained the ability to sit without support for at least 30 seconds. The children had other successes in the improvement or maintenance of skills measured on the Hammersmith Infant Neurological Examination between 24 and 36 months on treatment:· Ability to hold head up: 36 maintained, 3 gained, 0 lost this ability· Pivot while sitting: 15 maintained, 11 gained, 0 lost this ability· Stand with support: 6 maintained, 5 gained, 1 lost this ability· Walk while holding on: 1 maintained, 2 gained, 0 lost this abilityThe study showed overall continued reduction in serious adverse events and hospitalization over time. The rate of serious adverse events decreased by approximately 50% after each 12-month treatment period and a 78% reduction between the first and third year of treatment. The rate of hospitalization decreased from 1.24 per patient per year over 12 months to 0.70 hospitalizations per patient per year over 36 months. (Genentech.

Differences in Response to Antidepressants in Combination with Mood Stabilizers and Antipsychotics for Unipolar and Bipolar DepressionA study published in the Journal of Clinical Psychopharmacology is the first to explore clinical response rates to antidepressants in combination augmentation strategies with either antipsychotics or mood stabilizers and to illuminate the differences between response to similar pharmacotherapies in patients with unipolar and bipolar depression. Antidepressant prescriptions in bipolar disorder have surged in the past two decades, from 17.9% to 40.9% of patients, mostly based on the success of newer antidepressants in treating unipolar depression. They remain the leading treatment prescribed for bipolar disorder, despite inconsistent evidence for efficacy and the occurrence of adverse events, such as treatment-emergent affective switch (TEAS).READ MORE...The study relied on data from a research database for patients followed at the McGill University Health Center’s Mood Disorders Clinic for 2 or more years (mean, 7.5 years). It included 206 patients; 76 met the criteria for treatment-resistant depression (TRD), failing two or more trials with different antidepressants in either monotherapy or combination therapy for 3 or more weeks. The remaining 130 patients met criteria for bipolar disorder, all of whom had failed to respond to one or more trials with a mood stabilizer plus an antipsychotic. Clinical outcomes were determined by comparing changes on these behavioral scales between start of a treatment regimen and after 3 months of an unchanged regimen; scales were the 17-item Hamilton Depression Rating Scale (HAMD-17), Quick Inventory of Depressive Symptomatology (QIDS-C16), and Clinical Global Impression–Severity of Illness (CGI-S). Response was defined as 50% or greater reduction from the pretreatment HAMD-17 score, and remission was defined as a score of less than 7 on the HAMD-17 at the end point.At baseline, the TRD group had, on average, moderate to severe depression (HAMD-17: 23.86), with scores on QIDS-C16 of 15.0 and on CGI-S of 5.2. The bipolar group had, on average, mild to moderate depression (HAMD-17, 18.3), with scores on QIDS-C16 of 12.3 and on CGI-S of 4.5. Clinical improvements in depression severity were seen with the different treatment strategies:· Antidepressants plus antipsychotics produced significantly greater improvement on HAMD-17 for the TRD group (score, 9.2) vs. bipolar group (score, 5.1), but no significant differences on other scales: 5.6 vs. 4.5 on QIDS-C16 and 1.7 vs. 1.4 on CGI-S.· Antidepressants plus mood stabilizers showed marginally greater improvement on HAMD-17 for the TRD group (score, 8.8) vs. the bipolar group (score, 6.3); the combination of antidepressants, antipsychotics, plus mood stabilizers also showed marginally significant differences between the TRD group (score, 9.3) and the bipolar group (score, 6.9) on the HAMD-17. But other clinical scales failed to reveal significant differences in outcomes.Response and remission rates did not differ significantly between the two types of depression, nor did they differ based on any type of combination treatment. Response rates were 26% in the TRD group and 19% in the bipolar group for all treatment strategies; remission occurred in 5% of the TRD group and in 7% of the bipolar group. These low rates of remission reflect the refractory nature of depression in these patients.These data, seen in a natural clinical setting, highlight the importance of augmentation strategies in depression. The study also showed that the reduction of depressive symptoms was greater in the TRD group compared with the bipolar group when pharmacologic combinations included an antidepressant and that adding an antidepressant to the treatment regimen for bipolar depression increased the risk of TEAS, cycle acceleration, and mood destabilization in these patients. Taken together, these results raise questions about the use of antidepressants in bipolar disorder. (Moderie, C., et al. (2022).

Preventive therapies are also beneficial; they may be used in those with severe or frequent migraine attacks and in those with a poor response to acute treatments. Atogepant, a calcitonin gene-related peptide (CGRP) receptor antagonist, has been approved as a preventive treatment for migraine; it can be expected, therefore, that it could possibly be given in combination with sumatriptan.READ MORE...An open-label, randomized, 3-way crossover study evaluated the possibility of how administering the two drugs together affected pharmacokinetic parameters, and compared how the body absorbed, distributed, and eliminated the two drugs when given together compared to each drug given alone. The trial enrolled 30 healthy adults, of whom 27 completed the study; 29 received a single oral 100-mg dose of sumatriptan, 28 received a single oral 60-mg atogepant dose, and 27 received the drugs administered together. Blood samples were drawn to determine plasma drug concentrations on days 1, 8, and 15, and safety and tolerability were monitored by physical exams, vital signs, clinical lab tests, and ECGs.Most of the pharmacokinetic parameters were only minimally changed when atogepant was given with sumatriptan, compared to either drug given alone. The peak plasma concentration (Cmax) of atogepant was reduced by 22% when administered with sumatriptan. Coadministration delayed the median atogepant Tmax (time to maximum plasma drug concentration) by 1.5 hours. This lower Cmax and delayed Tmax could be attributed to the effect of sumatriptan on gastric emptying. However, these changes are expected to have minimal clinical relevance because use with sumatriptan was not shown to not affect the overall systemic exposure to atogepant.These results allay concerns about the safety and tolerability of using these two antimigraine medications together, leading to more options for treating severe or frequent migraines. Further studies are needed to confirm these findings. (Boinpally, R., et al. (2021).

As the rollout for the SARS-CoV2 mRNA vaccines was underway, allergic reactions rapidly led to recommendations that people with an immediate allergic reaction to the first dose shouldn’t receive additional doses. But this places those people at risk of contracting the disease.READ MORE...A review article published in JAMA Internal Medicine examined 22 studies and asked the question: What is the risk of an immediate severe allergic reaction (anaphylaxis) to a second dose of a SARS-CoV2 mRNA vaccine among individuals who had an immediate allergic reaction of any severity to their first dose? The researchers examined studies conducted from the onset of COVID-19 vaccination through October 4, 2021; immediate allergic reaction was defined as one that occurred within 4 hours of the first dose. The individuals received the second vaccine under the supervision of an allergist.The meta-analysis identified 1,366 individuals who had immediate allergic reactions to their first vaccination, among them, 78 persons who had suffered an anaphylactic reaction to the first dose. Of the 1,366 individuals, pooled analysis showed that 6 experienced severe immediate allergic reaction (absolute risk, 0.16%) and 232 developed mild immediate symptoms (absolute risk, 13.65%) to the second dose of the vaccine. Of the 78 persons who had suffered anaphylaxis after the first dose, 4 had a second severe allergic immediate reaction (absolute risk, 4.94%) and 15 had mild immediate symptoms (absolute risk, 9.54%). None of the 6 persons who experienced severe allergic reactions to the second dose died; 5 recovered after receiving IM epinephrine and the sixth recovered without treatment. Subgroup analysis, examining studies that permitted altered dosing, premedication before vaccination, or skin testing, didn’t result in alterations to these findings.These findings contradict the common assumption that a history of allergic reactions guarantees another to subsequent vaccine exposure. In such individuals, consultation with an allergist before the second vaccination is recommended. (Chu, D. K., et al. (2022).

They seek comments from interested parties: patients, patient advocates, health care professionals, academics, researchers, pharmaceutical industry, and other government entities.READ MORE...The FDA’s efforts to address the opioid crisis include a focus on encouraging appropriate disposal of unused opioids. Current recommendations for disposal of unused drugs include permanent collection sites, such as kiosks in pharmacies or at community take-back events. If such opportunities aren’t available, the FDA recommends flushing those opioids on the Flush List (safe to be disposed in that way) or mixing with an unpalatable substance and disposing in the household trash. All these methods have their drawbacks, from environmental concerns to worries about safety to concerns about cost and inconvenience. Data show that educating patients about disposal options increases the disposal rate of unused medications; it’s hoped that providing an easy, cost-free option along with education will further increase that rate.Patients commonly report having unused opioid analgesics after surgical procedures; studies show a range of 67% to 92% of patients, depending on the surgery, report excess opioid analgesics. Opioids used for chronic pain can also result in excess pills requiring disposal, due to changes in dose or medication, discontinuation of opioid treatment, or death of the patient. These unused opioids then end up sitting in their house, creating opportunities for nonmedical use, accidental exposure, overdose, and new cases of opioid addiction. Despite the risks associated with having unused opioid analgesics in the home, most studies found that fewer than 50% of patients report disposing of them. Patient education on the need to dispose of them has been shown to increase disposal rates; in one study that examined the effect of providing patient education, a take-home disposal method, or both, use of either intervention increased the disposal rate by about 12% and the combined intervention increased the disposal rate by 19.5%. It is reasonable to assume that mail-back envelopes are one such method that could increase this disposal rate.The FDA is anticipating that this REMS-mandated disposal program could complement programs already in place. Recognizing that dispensing mail-back envelopes with every opioid prescription would be inefficient, the FDA proposes the use of algorithms that could enable pharmacists to target those prescriptions most likely to result in unused medications (that is, when filling new prescriptions for acute pain treatment or when changing the dose, medication, or formulation in a recurring prescription).

Follow-Up Analysis Shows that Adding Isatuximab to Treatment for Resistant Multiple Myeloma Provides Continued SurvivalThe addition of the anti-CD38 monoclonal antibody isatuximab to pomalidomide-dexamethasone treatment resulted in a greater than 6-month difference in median overall survival compared to treatment without isatuximab in relapsed and refractory multiple myeloma. This finding was reported in a prespecified second interim analysis of a key secondary endpoint in the ICARIA-MM study; results of that study supported the March 2020 approval of isatuximab for multiple myeloma.READ MORE...ICARIA-MM was a randomized, multicenter, open-label phase 3 study that enrolled adults with relapsed or refractory multiple myeloma who had received at least two previous lines of therapy. This therapy could include lenalidomide and a protease inhibitor, but no prior pomalidomide treatment was permitted. Patients were recruited from hospitals in 24 countries worldwide; 307 patients were randomly assigned to receive isatuximab plus pomalidomide-dexamethasone (n = 154) or to pomalidomide-dexamethasone alone (n = 153).Median overall survival was 24.6 months in the isatuximab plus pomalidomide-dexamethasone group and 17.7 months in the pomalidomide-dexamethasone group (hazard ratio [HR], 0.76). Serious treatment-emergent adverse effects were observed in 111 patients (73%) who received isatuximab plus pomalidomide-dexamethasone, and in 90 patients (60%) who received pomalidomide-dexamethasone. At cutoff of follow-up, 18% of the patients in the isatuximab plus pomalidomide-dexamethasone group and 8% of patients in the pomalidomide-dexamethasone group remained on the study treatment; death had occurred in 60% of patients. Updated progression-free survival analysis showed a median duration of progression-free survival of 11.1 months with isatuximab plus pomalidomide-dexamethasone and of 5.9 months with pomalidomide-dexamethasone (HR, 0.60).This improved survival supports the assertion that this treatment should be considered as standard of care for patients with multiple myeloma refractory to usual treatments (lenalidomide and protease inhibitors).

A study published in the Journal of the American Geriatric Society examined this hypothesis, and further sought to learn if reliance on multiple sources of information about COVID-19 was associated with less vaccine hesitancy among a sample of Medicare beneficiaries.READ MORE...The Medicare Current Beneficiary Survey (MCBS) contains data collected from a nationally representative sample of Medicare beneficiaries. The MCBS COVID-19 Fall 2020 Rapid Response Supplement, administered between October and November 2020, included a study cohort of 7,278 beneficiaries, a weighted sample representing 43,829,153 community-dwelling Medicare beneficiaries. Respondents answered questions about their sources of COVID-19 information and about their presumptive vaccine uptake (the questions were posed before vaccines were available). The survey aimed to determine COVID-19 vaccine hesitancy, scored as 1 if they answered, “probably not, definitely not, not sure” and 0 if they answered, “definitely, probably,” to the question “Would you get a COVID-19 vaccine if available?” Then they analyzed these findings according to key independent variables: the reliance on formal vs. informal sources of COVID-19 information, and the total number of information sources the respondent relies on, both formal and informal. Informal sources include social media, the Internet, or friends and family. Formal sources include traditional news outlets, government guidance, and information from medical professionals.The survey demonstrated that 16% of respondents (n = 1,231) reported getting their information about COVID-19 from informal information sources. Vaccine hesitancy was found in 44% of those relying on informal information sources vs. 38% of those who reported relying on formal information sources. Relying on informal sources was associated with a 29% higher odds of vaccine hesitancy (OR, 1.29). Relying on more, varied sources of information on COVID-19 was associated with lower odds of vaccine hesitancy, with a decrease of 0.91 in odds ratio for each additional source used.These results can provide insights to guide future efforts that aim to build up positive attitudes toward the vaccine and to increase vaccine uptake. In addition, they add support to the importance of taking precautionary measures to address false anti-vaccination claims. The study has limitations, as the survey didn’t include Medicare beneficiaries living in long-term care facilities and, importantly, was conducted before the vaccines were available. But later events have strengthened the evidence for its hypothesis proving true. (Kim, J., Kim, Y., et al. (2022).

Essential medications are defined as those necessary to prevent, treat, or manage the most prevalent diseases in a population. The EMLc is an important tool; for most low- and middle-income countries, the list serves as a template for national drug formularies. But a study published in Archives of Diseases in Childhood documents that most essential enteral medications listed in both the 2011 and 2019 EMLc couldn’t be considered age-appropriate for children under age 6.READ MORE...The study sought to determine the appropriateness of all enteral formulations on the EMLc by assessing two important characteristics: swallowability and dose adaptability. Researchers defined age-appropriate formulations as ones which “a child of a specified age or age-group would have the natural ability to use (either directly or indirectly) without the product having to be altered from its original presentation before administration.” Two pharmacists evaluated each of the recommended medications for each of the five age-groups under age 12 and ranked them as 1 (not age-appropriate), 2 (possibly age-appropriate), or 3 (age-appropriate) for those two characteristics.When assessing swallowing ability, they used certain criteria to gain consistency in their evaluations:Liquids, oral powders/granules, dispersible tablets: appropriate from birth, with dose volumes under 10 mL being acceptable under age 5Crushed tablets, sprinkle capsules: appropriate from age 6 months, or the age at which a child can swallow solidsChewable tablets, dispersible tablets: appropriate from age 2, or the age at which a child can safely chew and swallow tabletsConventional tablets and capsules: not appropriate for those under age 5; children this age are incapable of swallowing the medication safelyEffervescent tablets: not appropriate for those under age 5, because of the need for large volumes, typically in excess of 100 to 200 mL.To examine dose adaptability, the evaluators compared the recommended doses in mg/kg body weight or mg/m2 BSA for each essential medicine, as given in the WHO formulary, to the mean body weight or BSA for each age-group. They determined whether the volume of a liquid or size/amount of a solid form was appropriate to deliver the recommended dose to a given age-group.The evaluation found that, in the 2011 edition of the EMLc, 77% of formulations were appropriate for older children (older than age 6). But for younger children, those percentages dropped: 34% were age-appropriate for preschoolers (ages 3 to 5), 30% were age-appropriate for toddlers (ages 1 to 2), 22% were age-appropriate for infants (ages 28 days to 11 months), and 15% were age-appropriate for neonates (ages 0 to 27 days). Overall, these proportions held true for EMLc 2019. The researchers further found that 55% of the active pharmaceutical ingredients were available in a variety of formulations that resulted in the drug being appropriate for all age-groups and that at least 47% had, at the minimum, one formulation (usually an oral liquid) that was considered appropriate for all age groups. But in practice, especially in low-income countries, the whole range of formulations aren’t readily commercially available. For example, only 33% of drugs on the 2011 EMLc were available in Nigeria in formulations suitable for younger children, significantly lower than the 52% to 57% availability seen in countries like the United States, the United Kingdom, and France.Going forward, all formulations included in the EMLc should be assessed for age-appropriateness, and that assessment should be a guide to development of new products or alternative administration strategies. Ensuring that age-appropriate formulations are actually available can help support decisions and strategies intended to provide access to essential medicines. (Orubu, E. S., Duncan, J., et al.

But clinicians hesitate to prescribe beta blockers in patients with respiratory disease who experience an MI, fearing that the beta blockers might precipitate bronchospasm and reduced pulmonary function in these patients. A retrospective Taiwanese study investigated use of beta blockers, and specifically of cardioselective beta blockers, in patients with chronic obstructive pulmonary disease (COPD) being treated in hospital after their first-ever MI.READ MORE...The study identified 65,699 patients with COPD in the Taiwan National Health Insurance Research Database who were prescribed beta blockers after their first MI from January 2001 to December 2013. After excluding patients who had been treated with both cardioselective and nonselective beta blockers, those younger than age 20, those who died during their hospitalization for that initial MI, and those who had been followed up for less than 90 days, the study enrolled 14,789 patients. The researchers examined patient records for all-cause mortality and for the secondary outcomes of hospitalization for heart failure, incidence of major cardiac or cerebrovascular events (MACCE), including death, revascularization, repeated MI, or ischemic stroke, and of major adverse pulmonary events (MAPE), such as exacerbations of COPD and hospitalizations due to pneumonia. The patients were categorized into two groups: 7,247 patients were prescribed cardioselective beta blockers during that hospitalization and 7,542 patients were prescribed nonselective beta blockers. There were no significant differences in most baseline characteristics between the two groups, and no significant differences in hospital treatment for the initial MI, including similar admission rates and ICU stays, the need for inotropic agents and intubation, and interventions for coronary artery disease.The patients who were prescribed cardioselective beta blockers had a lower risk of all-cause mortality than those who were prescribed nonselective beta blockers—8.9 vs. 9.6 events per 100 person-years (HR, 0.93), and of MACCE—13.2 vs. 13.9 events per 100 person-years (HR, 0.96), as well as of hospitalization for heart failure—3.3 vs. 3.8 events per 100 person-years (HR, 0.89). The incidence of MAPE was significantly lower in the cardioselective group compared to the nonselective group: 10 vs. 10.8 events per 100 person-years (HR, 0.94).Similar results were found in subgroup analysis between those prescribed the cardioselective beta blocker bisoprolol (n = 5,644; 74% of patients receiving cardioselective beta blockers) and those prescribed the nonselective beta blocker carvedilol (n = 4,881; 64.7% of patients receiving nonselective beta blockers). All-cause mortality was significantly lower with bisoprolol than with carvedilol at the end of follow-up—9.3 vs. 10.3 events per 100 person-years (HR, 0.90), as was hospitalization for heart failure—3.5 vs. 4.4 events per 100 person-years (HR, 0.84), and MAPE—10.5 vs. 11.5 events per 100 person-years (HR, 0.94). Incidence of MACCE was not significantly different between the two drugs: 14 vs. 14.7 events per 100 person-years (HR, 0.96).These results strongly suggest that patients with COPD who experience an MI can be prescribed beta blockers, but they should be cardioselective beta blockers, as they are safer and more effective than nonselective beta blockers in this population. The study has limitations, as it’s a retrospective study only; a randomized, controlled trial is still needed to confirm these beneficial effects. (Chung, C-M., Lin, M-S., et al. (2022).
