Background

For acute ischemic stroke, national practice guidelines recommend thrombolysis within a 4.5-h time window from symptom onset. Randomized trials with advanced neuroimaging have now examined extended thrombolytic time windows, and multiple meta-analyses have provided positive endorsements. However, these previous meta-analyses have not fully exploited the available data, examined quality of life, or reported the probability of clinically meaningful effects. This meta-analysis addresses these potential shortcomings.

Methods

We performed a i) systematic literature review up to August 1, 2025, of all randomized controlled trials comparing thrombolysis (alteplase or tenecteplase) with the assistance of advanced neuroimaging to standard, non-thrombolytic therapy in acute ischemic stroke patients with unknown time or beyond 4.5 h since symptom onset and ii) an umbrella review of previous meta-analyses addressing this issue. Our primary outcome was the mean difference in the utility-weighted modified Rankin Scale (uw-mRS) scores. Secondary outcomes were the absolute risk difference (ARD) for minor disability status and mortality. Bayesian random effects meta-analyses were performed assuming a normal-normal hierarchical model with non-informative priors, which permitted probability calculations for benefit, harm, and regions of practical equivalence (ROPE).

Results

Six original randomized trials of extended thrombolysis and 7 meta-analyses were identified but none had considered a uw-mRS score or reported direct probability statements regarding benefit or harm. Our primary uw-mRS outcome showed a ROPE probability of 99 % with only a 1 % probability of a clinically beneficial response with extended alteplase. There was also a 72 % probability that mortality increased by at least 1 life / 100 treated with extended thrombolysis.

Conclusions

In contrast with previous publications, this meta-analysis and umbrella review highlights the uncertainty of clinical benefits from extended thrombolysis treatment windows and the need for further high-quality research before this treatment is accepted into routine practice.
背景:对于急性缺血性卒中,国家实践指南建议在症状出现后4.5小时内溶栓。采用先进的神经成像技术的随机试验现在已经检查了延长的溶栓时间窗口,多个荟萃分析提供了积极的支持。然而,这些先前的荟萃分析并没有充分利用现有的数据,检查生活质量,或报告临床有意义的效果的可能性。这项荟萃分析解决了这些潜在的缺点。方法:我们对截至2025年8月1日的所有随机对照试验进行了系统的文献综述,比较了在先进神经影像学辅助下溶栓(阿替普酶或替奈普酶)与标准的非溶栓治疗在症状出现后未知时间或超过4.5小时的急性缺血性卒中患者中的效果。ii)对先前针对这一问题的荟萃分析进行了总结性回顾。我们的主要结果是效用加权修正兰金量表(uw-mRS)得分的平均差异。次要结局是轻微残疾状态和死亡率的绝对风险差异(ARD)。贝叶斯随机效应荟萃分析假设一个具有非信息先验的正态-正态分层模型,允许对收益、危害和实际等效区域(ROPE)进行概率计算。结果:确定了6项扩展溶栓的原始随机试验和7项荟萃分析,但没有一项考虑了uw-mRS评分或报告了关于益处或危害的直接概率陈述。我们的主要uw-mRS结果显示ROPE概率为99%,而延长阿替普酶治疗后临床有益反应的概率仅为1%。延长溶栓治疗的死亡率增加至少1 / 100的概率为72%。结论:与之前的出版物相比,本荟萃分析和总括性综述强调了延长溶栓治疗窗口期临床获益的不确定性,以及在该治疗被接受为常规实践之前需要进一步的高质量研究。

Objectives

Acute sciatica is a frequent cause of emergency department (ED) visits and hospital admissions. We evaluated the potential national cost savings of using ultrasound-guided transgluteal sciatic nerve block (TGSNB) in patients with acute sciatica who would otherwise be admitted.

Methods

We performed a Monte Carlo simulation with 10,000 iterations to compare the costs of usual care versus TGSNB targeted to patients who would otherwise require admission. Model inputs included national ED visits for acute sciatica, pre-block admission rates, admission costs, and procedural costs. The primary outcomes were per-patient savings among admitted patients and projected annual national savings.

Results

Targeted use of TGSNB in admission-eligible patients yielded mean per-patient savings of $11,974 (95 % UI: $6702–$18,527). Extrapolated nationally, this corresponds to $45.8 M (95 % UI $22.9 M–$74.0 M) in annual savings. Block costs were modest ($0.67 M (95 % UI: $0.46 M–$0.93 M)), and sensitivity analysis identified admission rates and costs as the main drivers of savings.

Conclusions

Adoption of TGSNB for severe sciatica in the ED may reduce admissions and generate meaningful healthcare savings. Prospective studies are needed to confirm clinical efficacy and implementation feasibility.
Capsule Summary:
  • 1.
    What is already known on this topic:
    Ultrasound-guided transgluteal sciatic nerve block (TGSNB) can rapidly relieve radicular pain; ED adoption is limited.
  • 2.
    What question this study addressed:
    What national cost savings could result if EDs target TGSNB to patients with acute sciatica who would otherwise be admitted?
  • 3.
    What this study adds to our knowledge:
    A Monte Carlo model (10,000 iterations) projects $11,974 per-treated-patient savings and $45.8 M annual national savings, with admission rate and admission cost as primary drivers.
  • 4.
    How this is relevant to clinical practice:
    Targeted ED TGSNB could reduce admissions and overall costs while supporting opioid-sparing pain management.
目的急性坐骨神经痛是急诊科(ED)就诊和住院的常见原因。我们评估了超声引导下经臀坐骨神经阻滞(TGSNB)治疗急性坐骨神经痛患者可能节省的国家成本。方法我们进行了1万次的蒙特卡罗模拟,比较常规护理与TGSNB的成本,否则将需要住院的患者。模型输入包括急性坐骨神经痛的全国急诊科就诊、阻滞前入院率、入院成本和手术成本。主要结果是住院患者的人均节省和预计的年度全国节省。结果TGSNB在符合入院条件的患者中有针对性地使用,平均每位患者节省11974美元(95% UI: 6702 - 18527美元)。在全国范围内,这相当于每年节省4580万美元(95%为2290万美元至7400万美元)。整体成本不高(0.67万美元(95% UI: 0.46万美元- 0.93万美元)),敏感性分析确定录取率和成本是节约的主要驱动因素。结论在急诊科采用TGSNB治疗严重坐骨神经痛可减少住院率,节省医疗费用。需要前瞻性研究来证实临床疗效和实施的可行性。胶囊总结:1。超声引导下经臀骨坐骨神经阻滞(TGSNB)可以快速缓解神经根痛;ED的采用是有限的。本研究解决了什么问题:如果急诊科以TGSNB为目标治疗急性坐骨神经痛患者,可能会导致哪些国家成本节约?这项研究增加了我们的知识:一个蒙特卡洛模型(10000次迭代)预测,以入院率和入院成本为主要驱动因素,每位治疗患者节省11974美元,每年全国节省4580万美元。这与临床实践的相关性:靶向ED TGSNB可以减少住院率和总体成本,同时支持阿片类药物疼痛管理。

Introduction

Sexually transmitted infections (STIs) remain a major public health concern, with emergency departments (EDs) serving as key sites for evaluation and treatment. Despite their importance, contemporary national-level data describing ED testing and treatment practices for patients presenting with symptoms suggestive of STI are limited.

Methods

We performed a retrospective cohort study of ED encounters from 2016 to 2024 using Cosmos, a large geographically diverse electronic health record database. Patients aged ≥15 years with symptoms suggestive of an STI were included. We examined diagnostic testing for Neisseria gonorrhoeae/Chlamydia trachomatis (NG/CT), Trichomonas vaginalis/bacterial vaginosis (TV/BV), syphilis, and HIV. Pregnancy testing was assessed among females aged 15–55 years. Empiric antibiotic treatment patterns were evaluated over time.

Results

Among 5,566,966 unique ED encounters, only 37.8 % underwent STI testing. NG/CT was the most frequently ordered test (34.1 %), followed by TV/BV (21.7 %), HIV (4.1 %), and syphilis (3.9 %). Among those tested for NG/CT, co-testing was 56.0 % for TV/BV, 9.3 % for syphilis, and 8.5 % for HIV. Pregnancy testing occurred in 68.5 % of eligible females. Nearly half (46.2 %) of NG/CT-tested patients received empiric treatment. Among TV/BV-tested patients, 13.4 % were empirically treated in the ED and 32.4 % were prescribed outpatient treatment.

Conclusion

Most ED patients who presented for conditions suggestive of STI did not undergo STI testing, and co-testing for other STIs was also uncommon. Empiric antibiotic therapy remains very common, occurring in approximately half of patients. These findings highlight opportunities to improve STI detection and treatment in EDs through standardized protocols and expanded use of co-testing.
性传播感染(STIs)仍然是一个主要的公共卫生问题,急诊科(ed)是评估和治疗的关键场所。尽管它们很重要,但目前国家层面的数据描述ED检测和对出现提示性传播感染症状的患者的治疗实践是有限的。方法:我们使用Cosmos(一个大型地理上多样化的电子健康记录数据库)对2016年至2024年ED就诊进行回顾性队列研究。年龄≥15岁且伴有性传播感染症状的患者被纳入研究。我们检查了淋病奈瑟菌/沙眼衣原体(NG/CT)、阴道毛滴虫/细菌性阴道病(TV/BV)、梅毒和HIV的诊断检测。对年龄在15-55岁的女性进行妊娠检测。经验性抗生素治疗模式随时间进行评估。结果在5,566,966例独特的ED就诊中,只有37.8%的患者接受了性传播感染检测。NG/CT是最常见的检查(34.1%),其次是TV/BV(21.7%)、HIV(4.1%)和梅毒(3.9%)。在接受NG/CT检测的人群中,TV/BV联合检测为56.0%,梅毒为9.3%,HIV为8.5%。68.5%符合条件的女性进行了妊娠检测。近一半(46.2%)的NG/ ct检测患者接受了经验性治疗。在接受TV/ bv检测的患者中,13.4%的患者在急诊科接受了经验治疗,32.4%的患者接受了门诊治疗。结论大多数表现为性传播感染的ED患者未接受性传播感染检测,其他性传播感染的联合检测也不常见。经验性抗生素治疗仍然非常普遍,约有一半的患者使用抗生素治疗。这些发现强调了通过标准化方案和扩大联合检测的使用来改善急诊科STI检测和治疗的机会。

Background

Video laryngoscopy (VL) is now ubiquitous in emergency airway management. Hyperangulated video laryngoscopy (HAVL) differs from standard geometry VL (SGVL) in blade design, technique, and required microskills, yet the two are often regarded similarly. Despite widespread use, no comprehensive taxonomy of HAVL-specific performance errors exists.

Methods

We conducted an observational study of video-recorded endotracheal intubations (ETIs) performed in an urban academic emergency department (2020–2024). Fifty HAVL videos were first analyzed to derive 20 performance errors, followed by 100 additional recordings to confirm findings and assess incidence. Two independent emergency physicians evaluated each recording for performance errors. Interrater reliability and correlations among errors, procedure duration, and intubation success were assessed using Cohen's κ, Gwet's AC, and Pearson's correlation.

Results

We identified 20 discrete performance errors associated with HAVL. All 100 recordings contained at least one performance error (pooled κ = 0.53, 95 % CI 0.48–0.58). The most common error was failure to engage the midline vallecula (56 %), and the least common was bougie delivery issues (1 %). Each additional performance error added approximately 3 s to intubation duration. Strong correlations were observed among several errors.

Conclusions

Performance errors during HAVL are common and interrelated. This novel taxonomy provides a framework for structured feedback, targeted training, and future investigation of HAVL technique and clinical outcomes.
背景:视频喉镜检查(VL)目前在紧急气道管理中无处不在。超角度视频喉镜(HAVL)与标准几何VL (SGVL)在叶片设计、技术和所需的微技能方面有所不同,但两者通常被认为是相似的。尽管广泛使用,但没有针对特定于havel的性能错误的综合分类。方法:我们对2020-2024年在城市学术急诊科进行的视频气管插管(ETIs)进行了观察性研究。首先分析了50个HAVL视频,得出了20个表现错误,然后进行了100个额外的记录,以确认发现并评估发生率。两名独立的急诊医生评估每一份记录的表现错误。使用Cohen’s κ、Gwet’s AC和Pearson’s相关来评估错误率、手术时间和插管成功之间的可靠性和相关性。结果:我们确定了20个与HAVL相关的离散性能错误。所有100个记录包含至少一个性能错误(pooled κ = 0.53, 95% CI 0.48-0.58)。最常见的错误是未能接合中线小瓣膜(56%),最不常见的是肿胀分娩问题(1%)。每个额外的性能错误使插管持续时间增加约3秒。在几个误差之间观察到很强的相关性。结论:hafl期间的表现错误是常见且相互关联的。这种新颖的分类法为有组织的反馈、有针对性的培训以及未来对HAVL技术和临床结果的研究提供了一个框架。

Background

This study aimed to develop a multimodal predictive model that integrates clinical variables, radiomic features (RFs), and deep learning–based features (DLFs) to improve prognostic accuracy in patients with blunt chest trauma (BCT).

Methods

We retrospectively analyzed 337 patients with BCT from three medical centers. Clinical and CT imaging data, including emergency and follow-up scans, were obtained. Features including radiomic (RF) and deep learning-based (DLF) descriptors along with delta features representing temporal changes were extracted. After sequential feature selection, the least absolute shrinkage and selection operator (LASSO) regression was applied to identify optimal features. Model development included clinical-only, imaging-only, and fused models, with performance evaluated using AUC, calibration curves, and decision curve analysis.

Results

Rib fracture count, multiple injuries, and hemopneumothorax-to-lung ratio (HPR) were identified as independent prognostic factors. The fusion model, particularly the delta-clinical-DLR model, achieved AUCs of 0.85 (95 % CI: 0.80–0.90) and 0.86 (95 % CI: 0.77–0.95) in the training and test sets, respectively. Significant improvements in net reclassification (NRI up to 0.76) and integrated discrimination (IDI up to 0.26) were observed compared to the clinical models alone.

Conclusions

Integrating multi-timepoint CT imaging with clinical variables through a multimodal fusion model significantly enhances the prognostic performance of BCT, providing a robust tool for individualized risk prediction and clinical decision-making.
本研究旨在建立一种综合临床变量、放射学特征(RFs)和基于深度学习的特征(DLFs)的多模式预测模型,以提高钝性胸外伤(BCT)患者的预后准确性。方法回顾性分析来自3个医疗中心的337例BCT患者。获得临床和CT成像数据,包括急诊和随访扫描。提取的特征包括放射学(RF)和基于深度学习(DLF)的描述符以及表示时间变化的delta特征。在序列特征选择之后,采用最小绝对收缩和选择算子(LASSO)回归来识别最优特征。模型开发包括仅临床模型、仅成像模型和融合模型,并使用AUC、校准曲线和决策曲线分析来评估性能。结果肋骨骨折计数、多发伤、血气胸肺比(HPR)是独立的预后因素。融合模型,特别是delta-clinical-DLR模型,在训练集和测试集的auc分别为0.85 (95% CI: 0.80-0.90)和0.86 (95% CI: 0.77-0.95)。与单独的临床模型相比,观察到净重分类(NRI高达0.76)和综合区分(IDI高达0.26)的显著改善。结论通过多模态融合模型将多时间点CT图像与临床变量相结合,可显著提高BCT的预后表现,为个体化风险预测和临床决策提供了强有力的工具。

We report a case of a 61-year-old man with a history of alcoholic cirrhosis and impaired mobility who presented to the Emergency Department (ED) with hepatic encephalopathy, cellulitis, sepsis, and extensive maggot infestation (myiasis). Maggots were recovered from the patient's skin, urethra, and rectum, and the burden of maggots in the urethra had led to bladder outlet obstruction. Blood cultures revealed polymicrobial bacteremia, including Ignatzschineria larvae.
Ignatzschineria larvae is a commensal bacterium that resides in the digestive tract of maggots. The organism is rarely pathogenic to humans, and case reports of Ignatzschineria larvae bacteremia are rare. This case demonstrates two uncommon complications of wound myiasis: bacteremia and bladder infestation, causing outlet obstruction and urinary retention. Patients who present to the Emergency Department with myiasis are at risk for bacteremia from both typical skin pathogens related to their wounds and pathogens associated with the maggots themselves.
我们报告一例61岁男性,有酒精性肝硬化和活动能力受损史,以肝性脑病、蜂窝织炎、败血症和广泛的蛆感染(蝇蛆病)就诊于急诊科。患者皮肤、尿道、直肠均有蛆恢复,尿道中蛆的负担导致膀胱出口梗阻。血液培养显示多种微生物菌血症,包括伊格纳茨氏幼虫。伊格纳茨氏幼虫是寄生在蛆消化道中的一种共生细菌。这种生物很少对人类致病,伊格纳茨氏杆菌幼虫菌血症的病例报告也很罕见。本病例显示两种不常见的伤口蝇蛆病并发症:菌血症和膀胱感染,引起出口阻塞和尿潴留。到急诊科就诊的蝇蛆病患者有感染细菌血症的风险,细菌血症来自与伤口相关的典型皮肤病原体和与蛆本身相关的病原体。

Background

Intentional drug overdose (IDO) is a major cause of emergency department (ED) presentations. While psychiatric and psychosocial factors are established contributors, many events occur without identifiable triggers. Emerging evidence suggests that rapid environmental changes may act as acute behavioral stressors influencing self-harm risk. This study investigates whether short-term increases in solar insolation and related atmospheric conditions are associated with IDO presentations, using a 15-day harmonic mean (HM15) model to detect individualized environmental deviations.

Methods

This retrospective cohort study included adults presenting with IDO to a tertiary ED in Muğla, Türkiye between July 1, 2019 and July 1, 2024. Environmental data—including solar insolation, temperature at 2 m (T2M), ultraviolet (UV) radiation, and humidity—were obtained from the NASA POWER database. For each case, index-day values were compared to the individual's preceding HM15 baseline.

Results

Among 515 IDO patients, solar insolation, T2M, and UV radiation on the index day were significantly higher than HM15 baselines (all P < 0.001). These deviations were most pronounced in spring and early summer, aligning with established peaks in suicide risk. In spring, a 15.6 % surge in solar insolation was observed, alongside significant increases in T2M and UV exposure. Similar abrupt shifts were noted in summer, while autumn and winter demonstrated mixed environmental patterns.

Conclusions

Acute rises in solar insolation, temperature, and UV radiation are temporally associated with increased IDO risk. The HM15 model may support real-time, meteorologically informed, AI-enhanced risk stratification in ED-based suicide prevention and merits evaluation for integration into clinical decision support systems.
背景:故意药物过量(IDO)是急诊科(ED)报告的主要原因。虽然精神病学和社会心理因素是确定的诱因,但许多事件的发生没有可识别的诱因。新出现的证据表明,快速的环境变化可能是影响自残风险的急性行为压力源。本研究使用15天调和平均(HM15)模型来检测个性化的环境偏差,研究了太阳日照和相关大气条件的短期增加是否与IDO表现有关。方法:本回顾性队列研究纳入了2019年7月1日至2024年7月1日期间在日本Muğla、出现IDO至三级ED的成年人。环境数据包括太阳日照、2米温度、紫外线辐射和湿度,这些数据都是从NASA POWER数据库中获得的。对于每个病例,将指标值与个体之前的HM15基线进行比较。结果515例IDO患者指标日日晒、T2M、UV辐射均显著高于HM15基线(P < 0.001)。这些偏差在春季和初夏最为明显,与自杀风险的既定峰值一致。在春季,观测到太阳日晒量激增15.6%,同时T2M和UV暴露量显著增加。夏季也出现了类似的突变,而秋季和冬季则表现出混合的环境模式。结论日晒、温度和紫外线辐射的急剧升高与IDO风险的增加有暂时的相关性。HM15模型可以支持实时、气象信息、人工智能增强的基于ed的自杀预防风险分层和价值评估,以整合到临床决策支持系统中。

Case presentation

A 94-year-old woman with no major medical history developed chest pain and experienced ventricular fibrillation at home. In accordance with written advance directives specifying refusal of “unreasonable or futile treatment,” no resuscitation was performed. After approximately ten minutes of asystole, spontaneous circulation resumed. Forty minutes later, the patient regained consciousness with complete neurologic recovery. Coronary angiography revealed significant coronary lesions that were successfully treated with two drug-eluting stents. The patient was discharged neurologically intact and remains well.

Discussion

This case documents a Lazarus phenomenon in the absence of any resuscitative maneuver—an event not previously described in the literature. Physiologic hypotheses may include delayed venous return, spontaneous myocardial reperfusion, or electrical recovery following ventricular fibrillation. The ethical implications are substantial, as the patient's interpretation of her advance directives differed markedly from the medical team's understanding. This case underscores both the physiological mystery of spontaneous circulation recovery and the ethical need for precise, individualized advance directives. It also highlights the importance of adaptability and clinical judgment when unexpected reversals of presumed death occur.
病例介绍:一名94岁女性,无重大病史,在家中出现胸痛和心室颤动。根据书面的预先指示,明确拒绝“不合理或无效的治疗”,没有进行复苏。大约停搏10分钟后,自然循环恢复。40分钟后,患者意识恢复,神经功能完全恢复。冠状动脉造影显示明显的冠状动脉病变,成功治疗两个药物洗脱支架。患者出院时神经系统完好,目前状况良好。讨论:这个病例记录了一个拉撒路现象,在没有任何复苏操作的情况下,这是一个以前没有在文献中描述的事件。生理假说可能包括静脉回流延迟、自发心肌再灌注或心室颤动后的电恢复。伦理影响是实质性的,因为患者对她的预先指示的解释与医疗团队的理解明显不同。这个病例强调了自发循环恢复的生理奥秘和精确的、个性化的预先指示的伦理需要。它还强调了在假定死亡发生意外逆转时适应性和临床判断的重要性。

Background

This study aimed to evaluate the prognostic value of clinical scoring systems and admission-based laboratory biomarkers in predicting mortality and morbidity among pediatric trauma patients.

Methods

We conducted a retrospective analysis of 88 pediatric trauma patients admitted to a tertiary-level pediatric intensive care unit between August 2024 and July 2025. Patients who died within the first 24 h were excluded. PRISM III, PELOD-2, SIPA, GCS, and VIS scores were calculated on the day of admission. Laboratory parameters including lactate, procalcitonin, and albumin levels were recorded. Morbidity was defined as persistent organ-specific dysfunction at discharge. Receiver operating characteristic (ROC) analysis was used to evaluate predictive performance.

Results

The overall mortality rate was 5.7 %, while 13.6 % of patients developed sequelae. Non-survivors had significantly higher PRISM III, PELOD-2, lactate, lactate/albumin ratio, and procalcitonin levels, along with longer PICU stay and greater need for mechanical ventilation and inotropic support. The lactate/albumin ratio showed the highest predictive value for mortality (AUC = 0.828). Patients with sequelae had significantly higher illness severity scores and elevated lactate-related markers. Transfusion needs were also more common in this group. Lactate/albumin ratio demonstrated strong negative predictive value (NPV = 95.6 %) for morbidity.

Conclusion

Both clinical severity scores and lactate-related biomarkers were associated with mortality and morbidity in pediatric trauma patients. In particular, the lactate/albumin ratio emerged as a useful early indicator of poor outcomes. These findings support the incorporation of combined scoring and biomarker strategies into early risk stratification protocols in pediatric trauma care.
背景:本研究旨在评估临床评分系统和基于入院的实验室生物标志物在预测儿科创伤患者死亡率和发病率方面的预后价值。方法:回顾性分析2024年8月至2025年7月在某三级儿科重症监护病房收治的88例儿科创伤患者。在最初24小时内死亡的患者被排除在外。入院当天计算PRISM III、PELOD-2、SIPA、GCS、VIS评分。记录实验室参数,包括乳酸、降钙素原和白蛋白水平。发病定义为出院时持续的器官特异性功能障碍。采用受试者工作特征(ROC)分析评价预测效果。结果:总死亡率为5.7%,有13.6%的患者出现后遗症。非幸存者的PRISM III、PELOD-2、乳酸、乳酸/白蛋白比和降钙素原水平显著升高,PICU停留时间更长,对机械通气和肌力支持的需求更大。乳酸/白蛋白比值对死亡率的预测价值最高(AUC = 0.828)。后遗症患者的疾病严重程度评分明显升高,乳酸相关标志物升高。输血需求在这一组中也更为常见。乳酸/白蛋白比值对发病率有很强的阴性预测价值(NPV = 95.6%)。结论:临床严重程度评分和乳酸相关生物标志物与儿童创伤患者的死亡率和发病率相关。特别是,乳酸/白蛋白比率成为不良预后的有用早期指标。这些发现支持将联合评分和生物标志物策略纳入儿科创伤护理的早期风险分层方案。
