Switching from Vitamin K Antagonists to Direct Oral Anticoagulants in Frail Elderly Patients with Atrial Fibrillation: Systematic Review and Meta-Analysis.

背景:体弱使老年心房颤动(AF)患者的抗凝管理复杂化,尤其是在已长期使用维生素K拮抗剂(VKA)治疗的情况下。在此类情况下,转换为直接口服抗凝药(DOAC)是否能改善结局仍不确定,指南推荐也有限。我们开展了一项系统评价和荟萃分析,比较体弱老年AF患者中由VKA转换为DOAC与继续使用VKA的结局。

Background: Frailty complicates anticoagulation management in older patients with atrial fibrillation (AF), particularly when long-term vitamin K antagonist (VKA) therapy is already established. Whether switching to a direct oral anticoagulant (DOAC) improves outcomes in this setting remains uncertain, and guideline recommendations are limited. We performed a systematic review and meta-analysis comparing outcomes of VKA-to-DOAC switching versus VKA continuation in frail elderly patients with AF.…

降钙素原诊断感染性胰腺坏死:系统评价与荟萃分析。
Procalcitonin for diagnosing infected pancreatic necrosis: a systematic review and meta-analysis.

背景:感染性胰腺坏死(IPN)是急性胰腺炎(AP)最严重的局部并发症之一,并在导致AP相关死亡中起核心作用。降钙素原(PCT)是一种优先对细菌感染产生反应的血清生物标志物,在理论上具有区分感染性与无菌性坏死的潜力。然而,此前的系统评价受限于样本量小、亚组分析浅显以及缺乏正式的证据分级。目前尚缺少以IPN作为临床终点进行专门更新的综合研究。…

BACKGROUND: Infected pancreatic necrosis (IPN) ranks among the most severe local complications of acute pancreatitis (AP) and plays a central role in driving AP-related death. Procalcitonin (PCT), a serum biomarker that responds preferentially to bacterial infection, has theoretical promise for differentiating infected from sterile necrosis. Earlier systematic reviews, though, are limited by small sample sizes, shallow subgroup analysis, and a lack of formal evidence grading. An updated synthesis that focuses specifically on IPN as the clinical endpoint is missing.…

Dual benefit of esketamine-based opioid-free anesthesia on postoperative pain and mental health outcomes in patients undergoing bariatric surgery: a randomized controlled trial.

病态肥胖患者合并抑郁和焦虑症状的风险较高。虽然减重手术是一种有效的治疗方法,但传统的基于阿片类药物的麻醉具有显著的围手术期风险。无阿片麻醉(OFA)提供了一种更安全的替代方案。艾司氯胺酮以其双重镇痛和快速抗抑郁作用而闻名,是OFA中一个有前景的组成部分。然而,支持其在减重手术患者中同时促进身体和心理恢复的临床证据仍然有限。…

Patients with morbid obesity are at a high risk of comorbid depressive and anxiety symptoms. While bariatric surgery is an effective treatment, conventional opioid-based anesthesia carries significant perioperative risks. Opioid-free anesthesia (OFA) presents a safer alternative. Esketamine, known for its dual analgesic and rapid antidepressant effects, is a promising component of OFA. However, clinical evidence supporting its simultaneous benefits for both physical and psychological recovery in bariatric patients remains limited.…
