Evidence-based, cost-effective management of gastric outlet obstruction: An algorithm of the JTACS Emergency General Surgery Algorithms Work Group
A structured, cost-conscious diagnostic and management algorithm for gastric outlet obstruction — CT with oral contrast plus EGD/biopsy to distinguish now-predominant malignant causes from benign peptic disease, then a staged pathway from endoscopic dilation/stenting to pyloroplasty or resection/bypass — giving acute-care surgeons a standardized approach to a heterogeneous EGS problem.
The impact of an intensive care telemedicine program on weaning from invasive ventilation: a secondary analysis of the ERIC trial
In the ERIC cluster-randomized trial, daily ICU tele-rounding did not improve weaning success rates but delivered significantly more spontaneous breathing trials (51% vs 27% of patient-days) and shortened mechanical ventilation duration in successfully weaned patients (7 vs 9 days) — telemedicine helps exploit existing weaning potential.
Arterial blood gas parameters during CPR and sustained ROSC in OHCA: a preplanned secondary analysis of the AMCPR trial
Higher intra-arrest PaO2 at 10 minutes was independently associated with sustained ROSC (aOR 1.02), with exploratory cut-offs of PaO2 >60 and PaCO2 <70 mmHg, while pH and lactate were not — suggesting arterial-line placement during ED resuscitation may add physiologic prognostic information beyond hemodynamics.
Artificial intelligence in the evaluation and treatment of osteoporotic and fragility fractures: A systematic review
AI/ML shows robust performance for fragility-fracture risk prediction (frequently outperforming FRAX), BMD estimation, and fracture detection, but methodological heterogeneity, bias, and limited prospective/multicenter validation still block clinical translation.
Prehospital National Early Warning Score outperforms shock index in predicting mortality and resource utilisation in adult trauma: A systematic review
Prehospital NEWS discriminated short-term trauma mortality far better than shock index (AUROC 0.87–0.96 vs 0.48–0.79) and reliably predicted transfusion and resource needs; SI still flags patients needing urgent intervention (elevated >0.9) but performs poorly in geriatric and isolated-TBI patients — supporting NEWS for EMS trauma triage.
Comprehensive Analysis of US Health Care Spending on Injuries
First comprehensive claims-based accounting (IHME Disease Expenditure Project, >40B claims) puts 2022 US injury spending at $106.7B, with 52% occurring outside acute care and falls dominating ($56.2B, 53%); distinct spending phenotypes by mechanism, demographics, and payer carry direct implications for how trauma systems are planned and financed.
Tranexamic acid for neurological outcomes and mortality in adults with hemorrhagic acute brain injury: an updated systematic review and meta-analysis of RCTs
Pooling TBI, spontaneous ICH, and SAH trials, TXA showed no benefit on short- or long-term mortality (RR 0.93 / 1.02), functional independence (RR 0.97), or dependence-or-death, and its effect on rebleeding remained inconclusive with no excess thromboembolism — arguing against routine TXA for intracranial hemorrhagic injury despite its extracranial hemorrhage-control role.
Effect of an app-guided ACLS algorithm on teamwork, non-technical skills, and workload in simulated in-hospital cardiac arrest: a randomized controlled feasibility trial
Among experienced clinicians, the 'CPR Leader' app did not improve guideline adherence, team performance, non-technical skills, or workload versus standard practice (and slightly delayed compressions in VF) — cognitive aids may help novices or mixed teams but add little for skilled providers.
Evaluating the effect of a regional training initiative on bystander CPR rates after out-of-hospital cardiac arrest
A year-long county-wide hands-only CPR training program showed no significant overall effect on bystander CPR rates or survival versus control counties, but was associated with an 8.6-percentage-point rise in bystander CPR for public-location arrests — community training may move the needle mainly in public settings, not homes.
Paediatric out-of-hospital cardiac arrest occurring before and after EMS arrival: a retrospective study
EMS-witnessed paediatric arrests had nearly double the adjusted odds of survival to discharge (AOR 1.91) and prehospital ROSC (AOR 1.83) versus bystander-witnessed events, while unwitnessed arrests fared far worse — underscoring early professional recognition/response and the need for paediatric-specific strategies.

Early stratification of risk for poor neurological outcome after cardiac arrest is improved with processed EEG data
Adding early (6-hour) processed EEG metrics (suppression ratio, BIS) to routine clinical/lab data significantly improved ML prediction of poor neurological outcome after cardiac arrest (AUC 0.88 long-term, 0.86 at discharge) versus either data source alone — a promising early risk-stratification aid pending external validation.
Transoesophageal echocardiography during CPR for cardiac arrest: A scoping review
Intra-arrest TEE is highly feasible (80–100% insertion, few complications), shifts chest-compression position in 19–76% of cases and alters management in 31–48%, and links compressions over the LVOT/aortic valve to worse ROSC — yet the two existing RCTs show no improvement in survival or neurological outcome, so its patient-centred benefit remains unproven.
Phenotyping Sepsis at Emergency Department Presentation Using Early Clinical Data: A Multicenter Cohort Study
k-means clustering of nine routine ED variables in the Korean Sepsis Alliance registry identified six reproducible sepsis phenotypes (7-day mortality 6.7%–31.8%) that behave as a continuous severity spectrum; decomposing bundle non-compliance separates appropriate withholding from urgency-related delay — a distinction one-dimensional severity scores miss, relevant to phenotype-stratified resuscitation.
