Methods: This retrospective cohort study evaluated adult civilian patients (≥18 years) treated for spinal gunshot wounds at Latin American institutions between 2014 and 2022. Demographic, clinical, and injury characteristics, treatment approaches, and infectious complications were analyzed. Results: After exclusions, 292 patients, primarily adult males (n=251, 86.0%) with a mean age of 32.6 years (standard deviation=11), were included. Most injuries affected the thoracic (n=135; 46.2%) and lumbosacral (n=95; 32.5%) spine. Infectious complications occurred in 20 patients (6.8%), including spinal infections (n=3; 1.0%), non-spinal infections (n=6; 2.1%), and wound infections (n=11; 3.8%). Most patients received prolonged antibiotic prophylaxis. The median duration of antibiotic administration was significantly increased in patients with dirty wounds (p<0.001) and high-velocity injuries (p=0.001). However, the duration of antibiotic administration did not influence spinal infection rates. Conclusions Our findings indicate a low incidence (1%) of spinal infections among patients with spinal gunshot wounds. Prolonged antibiotic use failed to reduce the risk of spinal infectious complications. Standardized guidelines for antibiotic prophylaxis in these injuries remain necessary to optimize care.

Background: While multidimensional and interdisciplinary assessment of older adult patients improves their short-term outcomes after evaluation in the emergency department (ED), this assessment is time-consuming and ill-suited for the busy environment. Thus, identifying patients who will benefit from this strategy is challenging. Therefore, this study aimed to identify older adult patients suitable for a different ED approach as well as independent variables associated with poor short-term clinical outcomes. Methods: We included all patients ≥65 years attending 52 EDs in Spain over 7 days. Sociodemographic, comorbidity, and baseline functional status data were collected. The outcomes were 30-day mortality, re-presentation, hospital readmission, and the composite of all outcomes. Results: During the study among 96,014 patients evaluated in the ED, we included 23,338 patients ≥65 years—mean age, 78.4±8.1 years; 12,626 (54.1%) women. During follow-up, 5,776 patients (24.75%) had poor outcomes after evaluation in the ED: 1,140 (4.88%) died, 4,640 (20.51) returned to the ED, and 1,739 (7.69%) were readmitted 30 days after discharge following the index visit. A model including male sex, age ≥75 years, arrival by ambulance, Charlson Comorbidity Index ≥3, and functional impairment had a C-index of 0.81 (95% confidence interval, 0.80–0.82) for 30-day mortality. Conclusion Male sex, age ≥75 years, arrival by ambulance, functional impairment, or severe comorbidity are features of patients who could benefit from approaches in the ED different from the common triage to improve the poor short-term outcomes of this population.

BACKGROUND: Severe aortic stenosis (AS), leads to pathological left ventricular remodeling that may worsen with concomitant overweight and obesity (OW/O). METHODS: We aimed to prospectively analyze the impact of OW/O on ventricular remodeling in severe AS, by evaluating the percentage of intraendomyocardial fibrosis (PIEF) and the percentage of infiltrating intraendocardial lipid vacuoles (PIELV) and its relationship to global longitudinal strain (GLS) in patients with OW/O. RESULTS: 44 patients with severe AS were included, 13 non-obese (29%) and 31 OW/O (71%), all of them with left ventricular ejection fraction ≥ 55%. GLS was evaluated with 2D speckle tracking. During valve replacement, an endocardial biopsy was obtained, where PIEF and PIELV were analyzed. Patients with higher PIEF and PIELV had greater body mass index (p < 0.0001) and worse GLS (p < 0.0053). A GLS cut-off point < -14% had a sensitivity of 75%, and a specificity of 92.8% to detect important PIEF (AUC: 0.928, 95% confidence interval: 0.798–1.00). On multivariate analysis, OW/O and PIELV were independently associated to the PIEF, and OW/O and PIEF were independently associated to GLS. A high correlation between the amount of PIELV and PIEF were found. CONCLUSION: Patients with severe AS and OW/O have greater PIEF and PIELV, suggesting more pathological remodeling. GLS is useful to detect subclinical myocardial injury and is potentially useful for endomyocardial fibrosis detection. The presence of higher PIELF may be a trigger factor for the development of intraendomyocardial fibrosis.

OBJECTIVE: To propose and evaluate the effectiveness of a telerehabilitation platform designed for patients with rotator cuff (RC) tears. METHODS: During the first study phase, a virtual service platform that included information on RC tear pathology, joint care, and a series of instructions regarding therapeutic exercise was designed and created. Subsequently, in the clinical phase, a quasi-experimental study was performed. The platform was tested on patients and evaluated at baseline and at 1, 2, 3, and 6 months with respect to their pain levels and functionality on the Constant-Murley (CM) scale. RESULTS: Eleven patients were included, 5 women and 6 men, with a median age of 55 years (range, 42–68 years). Pain diminished from a baseline value of 64 mm (range, 40–80 mm) to 16 mm (range, 0–30 mm) at 6 months (p<0.001). Points on the CM scale rose from a baseline value of 54 points (range, 51–66 points) to 85 points (range, 70–100 points) at 6 months (p=0.001). Functionality in daily living and work activities, movement, and strength exhibited significant changes at 6 months (p<0.05). CONCLUSION: Significant changes were observed in pain and functionality in this group of participants who used a telerehabilitation platform. To the best of our knowledge, this is the first study that included a specific program for RC tears.
