Importance Hospital-based shootings represent an extreme form of workplace violence, with notable consequences for staff, patients, and visitors. Despite growing concern, these events remain poorly understood. Objective To categorize hospital-based shootings from 2012 to 2024 and incorporate prior published events between 2000 and 2011 to examine trends in shootings over a 25-year span. Evidence Review Events in this systematic review of acute care hospital–based shootings in the US from January 1, 2012, through December 31, 2024, with subgroup analysis of previously published data trending shootings over 25 years (January 1, 2000, through December 31, 2024), were identified using EBSCO Regional Business News, ProQuest US Newsstream Collection, Gun Violence Archive, and Google News Search. Selected shooting events involved at least 1 injured person (a nonperpetrator or perpetrator) that occurred within or on the immediate property of the hospital. Findings A total of 327 news articles of unique hospital-based shooting events (5.2 per year per 1000 hospitals) were included from a review of 6658 articles, spanning 47 US states (94.0%). There was an overall incidence of 25.2 hospital-based shootings per year. Between 2012 and 2024, shootings increased by a mean (SD) of 1.7 (0.5) events per year, from 14 to 34 events (8.4% increase per year). Large hospitals accounted for the highest rate of shootings (258.1 events per 1000 hospitals). Events primarily occurred in urban settings (314 [96.0%]), and 161 (49.2%) occurred in the US South. Nearly one-third (105 [32.1%]) were potentially preventable by weapons screening. From 2000 to 2024, shootings increased by a mean (SD) of 1.1 (0.2) events per year, from 6 to 34 events (6.4% increase per year). A positive correlation was found in annual firearm fatalities in hospital settings and US firearms fatalities overall between 2012 and 2023 ( r = 0.42). Conclusions and Relevance This systematic review found that hospital-based shootings in the US have increased steadily over the past 25 years, representing an intersection between broader national trends in workplace and firearm violence. Large hospitals, those in the US South, and hospitals in urban communities are particularly at-risk settings. These findings underscore the need for hospital-specific prevention strategies, including consideration of weapons screening technology, alongside broader societal efforts to address rising firearm violence.

Background: Polydactyly surgery rates and trends are poorly characterized. The purpose of this study was to characterize national pediatric polydactyly management by examining operative and procedural trends over time, evaluating timing of treatment, identifying factors associated with interventions, and comparing costs and complications. Methods: We used the PearlDiver national administrative claims database to identify pediatric patients aged 18 and under with a diagnosis of polydactyly (2010-2023). We analyzed patients who received procedures coded as surgical correction or suture ligation, then characterized rates and factors associated with each intervention, and investigated postoperative complication rates. Results: Of 42 543 polydactyly patients, 3880 patients (9.1%) underwent surgery, and 5612 patients (13.2%) underwent procedures coded as suture ligation. Over the past decade, the incidence of polydactyly diagnosis and surgery has decreased, while rates of procedures coded as suture ligation have not changed significantly. In 2010, 12.0% of patients underwent surgery, compared to 7.3% in 2020. Patients of ages 1 to 2 years comprised the greatest proportion of the population who underwent surgical operations at 1729 patients (36.0%), and patients of ages 0 to 1 year comprised the greatest proportion of the population who underwent suture ligations at 3327 patients (51.0%) ( P < .001). Younger age at diagnosis and higher comorbidity index were associated with a greater likelihood of surgery, while greater mean family income was associated with a lower likelihood. Among treatment categories, surgery was associated with greater 1-year and total payer-reimbursed costs ( P < .05). Conclusions: We observed a declining incidence of pediatric polydactyly and polydactyly surgery. These findings may inform future guideline development and discourse for pediatric hand care.

Abstract Globally, gastric adenocarcinoma is the fourth leading cause of cancer mortality and a major cancer disparity in the United States. Chemoprevention strategies are lacking for high-risk individuals with gastric premalignant conditions (GPMC). Curcumin, the principal curcuminoid in turmeric, exerts immunomodulatory effects in the epithelium and against Helicobacter pylori, and studies suggest chemoprevention potential. We conducted a double-blind, phase IIa randomized controlled trial in high-risk populations in Puerto Rico and Honduras. We investigated the utility of a bioavailable formulation of curcumin (Meriva) among individuals with H. pylori–negative GPMC, specifically, multifocal atrophic gastritis (MAG) or gastric intestinal metaplasia (GIM). Patients were 1:1 randomized to 1,000 mg Meriva daily or placebo for a 6-month intervention with endoscopy at baseline and 6 months. Outcomes included assessment of epithelial cytokine and chemokine levels, histology, and DNA damage as assessed by γ-H2AX phosphorylation IHC. Of the 110 subjects screened, 50 participants were randomized, and 48 completed the trial. A significant reduction in gastric mucosal IL1β levels from baseline in the gastric body, the primary endpoint, was observed in the Meriva group (P = 0.032). Changes in epithelial IL8, TNFα, and inducible protein 10 levels and gastric mucosal histology and DNA damage (secondary endpoints) were similar between arms. Curcumin (Meriva) was safe, well-tolerated, and showed potential as a curcuminoid chemoprevention agent in H. pylori–negative patients with GPMC. A potential reduction in gastric inflammation as measured by gastric mucosal IL1β levels was observed. Further studies are warranted, including studies in H. pylori–positive individuals, based upon the curcuminoid direct effects on H. pylori. Prevention Relevance: Gastric adenocarcinoma is a leading cause of cancer mortality worldwide. Chemoprevention candidates for GPMCs are limited. This randomized phase IIa trial evaluated a bioavailable curcumin formulation in high-risk individuals with MAG and GIM. The results support further study of curcuminoids for gastric cancer risk reduction. See related Spotlight, p. 387 See related article by Morgan et al., p. 391

Background Recent studies have disputed the association between bisphenol A (BPA) and endometriosis. This updated meta-analysis was conducted to investigate the impact of BPA exposure on endometriosis. Methods This study evaluated BPA exposure and endometriosis risk, analyzing studies from Web of Science, PubMed, Embase, Cochrane Library, and Chinese databases (CNKI, CBM, Wanfang, VIP) through August 2025. Methodological quality was assessed via the Newcastle-Ottawa Scale (NOS) and the Agency for Healthcare Research and Quality Tool (AHRQ). Heterogeneity was quantified using I 2 statistics. Pooled odds ratios (ORs) and 95% CIs were calculated using fixed- or random-effects models according to heterogeneity. Subgroup analysis, sensitivity analysis, and publication bias assessment were supplemented to validate the overall finding. Results Seven studies comprising 2,488 participants were included in quantitative synthesis. The meta-analyses demonstrated that BPA exposure was associated with a statistically significant increase in endometriosis risk (OR = 1.36, 95% CI = 1.13–1.63, p = 0.008). Additionally, subgroup analysis indicated that BPA exposure may further elevate endometriosis risk in cases with different regions, populations, and measurement methods. Sensitivity analysis confirmed that the results of these meta-analyses were relatively robust. No publication bias was detected.
