This case report describes a rare instance of cardiac arrest caused by tension pneumopericardium resulting from an esophago-pericardial fistula due to a sharp foreign body, which was successfully managed through emergent pericardiocentesis, endoscopic foreign body removal, and surgical intervention.
This retrospective observational study of over 41,000 incidents in English inpatient mental health services reveals that restrictive practices operate as a two-stage system where service configuration determines restraint frequency and ward-level context influences escalation to seclusion, suggesting that reduction strategies must target both incident rates and the processes governing escalation.
This retrospective cohort study developed and validated a nomogram based on six independent predictors—estimated fetal weight >4000 g, abdominal circumference–head circumference difference ≥2.5 cm, gestational diabetes, maternal BMI >28 kg/m², short stature ≤150 cm, and prolonged second stage of labor—to effectively stratify the risk of shoulder dystocia during vaginal delivery.
This study demonstrates that early volumetric and signal enhancement ratio-based functional tumor volume reductions observed on DCE-MRI after just one cycle of neoadjuvant chemotherapy serve as superior predictors of clinical response and recurrence-free survival compared to traditional size-based metrics or later assessments in breast cancer patients.
This longitudinal study of Chinese adults found that experiencing probable respiratory sarcopenia at least once during follow-up is associated with an increased risk of developing incident frailty, suggesting that PEFR-based screening serves as a useful population-level signal for frailty risk despite non-monotonic patterns across repeated measurements.
This case report describes a rare instance of concurrent Pneumocystis jirovecii pneumonia and Guillain-Barré syndrome in a lung cancer patient following chemoradiotherapy, emphasizing the critical need for early, multi-modal diagnostic assessment to distinguish overlapping infectious and immune-mediated complications from treatment-related toxicity.
This case report describes a rare instance of a giant, asymptomatic tubulocystic retroperitoneal lymphangioma in a 47-year-old woman that was successfully treated with complete surgical excision despite significant mass effect on the ascending colon, highlighting the importance of considering intervention for large cystic lesions even in the absence of symptoms.
This study demonstrates that ventral dartos tissue in patients with hypospadias and chordee exhibits significantly lower MMP-1 and higher α-SMA gene expression compared to dorsal tissue, suggesting that regional molecular differences in extracellular matrix remodeling and fibrotic activity contribute to penile curvature.
This longitudinal study of Chinese medical students found that while neurophobia was not associated with academic performance, it was consistently linked to a reduced interest in pursuing neurology careers.
This case-control study reveals that patients with atrial septal aneurysm exhibit significantly higher levels of anxiety and depression compared to healthy controls, suggesting a previously unrecognized link between this cardiac anomaly and psychological distress.
