Study Summary: Emergent Carotid Stenting in Acute Stroke ThrombectomyA multicenter registry study in Catalonia (2017–2023) evaluated outcomes in 578 patients with acute ischemic stroke and tandem lesions (large-vessel occlusion plus extracranial carotid stenosis). Patients were divided into two groups: those who received emergent carotid artery stenting (E-CAS) and those who did not (non-CAS).Key Findings: Favorable outcomes (modified Rankin Scale 0–2) were more common in the E-CAS group at: 90 days: 46% vs. 37% 1 year: Odds ratio 1.35 Recanalization rates were higher with E-CAS: 92% vs. 73% No significant differences in: Hemorrhagic transformation at 36 hours (though a trend toward higher rates with E-CAS) 1-year mortality Conclusion:Emergent carotid stenting during thrombectomy may improve functional outcomes and recanalization without significantly increasing bleeding or mortality. However, as this was not a randomized trial, results should be interpreted cautiously. Further randomized studies are needed.  Ezcurra-Díaz G et al.

While short-term use appeared safe, prolonged use may pose risks (e.g., sedation, falls, respiratory depression). Clinicians are advised to reconsider routine perioperative use of gabapentinoids.  Baos S et al.

This massive meta-analysis of 484 randomized, double-blind, placebo-controlled trials (104,176 participants) quantified the blood pressure–lowering effects of major antihypertensive drug classes and their combinations. It introduces a new intensity-based classification system and an online calculator to predict BP-lowering efficacy based on drug, dose, and baseline BP.Study Design: 484 trials, 104,176 participants 5 major drug classes: ACE inhibitors, ARBs, β-blockers, calcium channel blockers (CCBs), and diuretics Focus: Placebo-corrected reduction in systolic BP (SBP) Mean baseline BP: 154/100 mm Hg Mean follow-up: 8.6 weeks Key Findings Monotherapy (Standard Dose): Average SBP reduction: 8.7 mm Hg By class: ACE inhibitors: 6.8 mm Hg ARBs: 8.5 mm Hg β-blockers: 8.9 mm Hg CCBs: 9.5 mm Hg Thiazide diuretics: 10.8 mm Hg Dose Doubling:Adds ~1.5 mm Hg SBP reduction (except β-blockers, which add only ~0.5 mm Hg) Dual Therapy (Standard Dose of Each): Average SBP reduction: 14.9 mm Hg Dose doubling adds ~2.5 mm Hg more Triple Therapy: SBP reduction: Up to 22.5 mm Hg (quadruple therapy even higher in one trial)

Practice Pearls: “Skip Leg Day” (Sometimes)For PAD patients who can’t tolerate leg workouts, upper body aerobic training is a strong, evidence-backed alternative. It’s not just a workaround—it’s a workout. CitationAhiskali GN, Demirel A, Yamikan H, Kutukcu EC.

Buelt, Andrew | 2:13 PM (1 hour ago) |  | to mehttps://jamanetwork.com/journals/jama/fullarticle/2833338 Conclusions and Relevance  These results support use of metformin for treatment of symptomatic knee osteoarthritis in people with overweight or obesity. Because of the modest sample size, confirmation in a larger clinical trial is warranted.    Lee S et al. Live zoster vaccination and cardiovascular outcomes: A nationwide, South Korean study. Eur Heart J 2025 May 5; [e-pub]. (https://doi.org/10.1093/eurheartj/ehaf230) In a new South Korean study, researchers evaluated nearly 1.3 million people (age ≥50) who were entered into a nationwide database. In an analysis adjusted for numerous confounders and with an average follow-up of 6 years, people who received a VZV vaccine had significantly lower risk (by ≈25%) for overall adverse cardiovascular events, heart failure, cerebrovascular disorders, ischemic heart disease, thrombotic disorders, and arrhythmias.  https://pubmed.ncbi.nlm.nih.gov/40658956/ Conclusion: Findings indicate that VNPs were more effective than NRT for smoking cessation in this population. Given the challenges for cessation among these socially disadvantaged populations, VNPs present a promising treatment option for this priority group.   https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0326804   We did not find that haloperidol was arrhythmogenic or increased mortality in these largely short-duration trials. Further research to clarify actual clinical outcomes related to QTPmeds is important to inform safe prescribing practices.

https://www.nejm.org/doi/10.1056/NEJMoa2504544  During follow-up ranging from 12 to 52 weeks, fewer patients had severe exacerbations in the albuterol/budesonide group than in the albuterol group (5% vs. 9%). Patients in the albuterol/budesonide group had less than half the total exposure to systemic glucocorticoids as those in the albuterol group (mean, 23 vs. 62 mg per year).   Clinical Practice: This study supports the use of an as-needed combination of albuterol and budesonide in reducing severe asthma exacerbations in patients with mild asthma who are inadequately controlled by SABA alone. This aligns with current recommendations by the Global Initiative for Asthma (GINA), which advocates for an inhaled corticosteroid plus a fast-acting bronchodilator as rescue therapy across all treatment steps for patients aged 12 years and older.   https://www.clinicalkey.com/#!/content/playContent/1-s2.0-S0140673625004398?returnurl=https:%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0140673625004398%3Fshowall%3Dtrue&referrer=https:%2F%2Fpubmed.ncbi.nlm.nih.gov%2F  Clinical Recommendation: The findings support the practice of initiating DOAC treatment within 4 days of an acute ischemic stroke in patients with atrial fibrillation, as it reduces the risk of early recurrent ischemic stroke without increasing hemorrhagic complications. This challenges the traditional approach of delaying anticoagulation to avoid potential bleeding risks.   https://www.ahajournals.org/doi/full/10.1161/CIRCULATIONAHA.125.074544?rfr_dat=cr_pub++0pubmed&url_ver=Z39.88-2003&rfr_id=ori%3Arid%3Acrossref.org  reduce the necessity for surgical intervention. Clinical Recommendations: Given their proven cardiovascular benefits, safety profile, and cost-effectiveness, high-dose statins should be strongly considered for patients with small AAAs, particularly those without contraindications.

https://publications.aap.org/pediatrics/article/156/1/e2024070175/202234/Infant-Antibodies-After-Maternal-COVID-19?autologincheck=redirected  Objective:The study aimed to evaluate the kinetics and duration of maternally derived antibodies in infants up to 6 months old, following maternal COVID-19 vaccination during pregnancy or postpartum. Study Design:A prospective multicenter cohort study was conducted across nine U.S. academic sites, enrolling infants born to mothers vaccinated with 2- (n=280) or 3-dose (booster) monovalent mRNA vaccines during pregnancy (n=202) or postpartum (n=36). Primary Outcomes: Antibody Levels: Significantly higher geometric mean titers (GMTs) of binding and neutralizing antibodies (nAb) were observed at birth and 2 months in infants of mothers who received a booster dose during pregnancy compared to those who received 2 doses or were vaccinated postpartum. Sustained Antibody Levels: Higher titers against the vaccine strain persisted up to 6 months in infants of boosted mothers, although not for the Omicron BA.1 and BA.5 variants.    https://pubmed.ncbi.nlm.nih.gov/40478588/   Objective:The study aimed to determine if mailed self-collection kits for CCS, with or without additional patient navigation, could improve screening participation compared to standard telephone reminders. Study Design:This was a pragmatic, parallel, single-blinded, randomized clinical trial conducted within a publicly funded safety-net health system in Houston, Texas. It included 2474 participants who were overdue for CCS. Primary Outcomes: Participation Rates: Among those who received a telephone reminder and mailed self-collection, 41.1% participated in screening, compared to 17.4% who received a telephone reminder alone. When patient navigation was added to mailed self-collection, participation increased to 46.6%. Effectiveness: Self-collection kits significantly improved participation, with a relative participation of 2.36 times higher than telephone reminders alone. Adding patient navigation further modestly increased participation to 2.68 times higher.

These factors are estimated to account for about 50% of the global burden of cardiovascular disease. Lifetime Risk Estimates: Among individuals free of these risk factors at age 50, the lifetime risk of cardiovascular disease was 13% for women and 21% for men. For those with all five risk factors, the lifetime risk jumped to 24% for women and 38% for men. Significance of Risk Factor Modification: Adjusting certain risk factors during midlife, particularly managing hypertension and quitting smoking, led to the most significant gains in life expectancy free of disease. For instance, controlling hypertension between ages 55 and 60 yielded the most additional life-years free of cardiovascular disease. Quitting smoking during the same period was associated with the most additional life-years free of death from any cause.    https://jamanetwork.com/journals/jama/fullarticle/2834632 Study Design: This was a phase 2, randomized, double-blinded trial with participants enrolled from 150 sites across 8 countries. The study spanned from January 2022 to June 2023, with analyses completed by March 2024. Participants received indapamide, amlodipine, or olmesartan as background therapy. Those with a specified range of 24-hour mean ambulatory systolic blood pressure (SBP) were then randomized to receive either a single subcutaneous dose of 600 mg zilebesiran or placebo. Efficacy Results: At 3 months, zilebesiran significantly reduced the 24-hour mean ambulatory SBP compared to placebo across all cohorts: Indapamide: -12.1 mmHg Amlodipine: -9.7 mmHg Olmesartan: -4.5 mmHg Similar reductions were observed in office SBP measurements at 3 months.    https://pubmed.ncbi.nlm.nih.gov/40578930/   Primary Outcomes: Discontinuation of Opioid Therapy: Patients in the greater SDM group were less likely to discontinue opioid therapy 3 months post-baseline compared to those in the lesser SDM group (Relative Risk: RR of 0.56). Opioid Prescribing Frequency: Over a 12-month period, patients in the greater SDM group experienced more frequent opioid prescriptions (RR of 1.24). Secondary Outcomes: Physical Function: Interestingly, physical function was slightly worse in the greater SDM group, but this difference was not deemed clinically significant. Back-related Disability: Both greater opioid use and SDM were associated with increased back-related disability and worse physical function, yet these findings were also not clinically significant. No significant SDM x opioid therapy interaction effects were observed, indicating that more frequent opioid use coupled with SDM did not lead to better patient outcomes in pain, function, or health-related quality of life (HRQOL).
