Clinicians should refer patients for liver transplant evaluation after any decompensation event—such as ascites or variceal bleeding—regardless of MELD score. After a first decompensation, 5-year mortality is 20–30%; after a second, it rises to 80–90%. Refractory ascites carries a 50% 1-year mortality, and overt hepatic encephalopathy has a 25–40% 1-year mortality. After an initial variceal bleed, the 1-year rebleeding risk is 60% without prophylaxis. There are no strict BMI or age cutoffs, and frailty has minimal effect on post-transplant outcomes. Substance use, including alcohol, is not a contraindication to referral—current guidelines no longer require a 6-month abstinence period. CitationsKing LY et al.

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.
