Heparin may mitigate secondary brain injury in subarachnoid hemorrhage (SAH), but its effect on survival in non-traumatic SAH (NSAH) remains uncertain. This study aimed to investigate the association between early prophylactic heparin use (within 72 h of admission) and mortality outcomes in patients with NSAH.

Medical staff frequently experience sleep deprivation, impacting both their health and patient care quality. Understanding brain network changes under sleep deprivation can guide preventive strategies. This study aims to determine how total sleep deprivation (TSD) alters brain network topology in medical professionals.

We consider étale Hausdorff groupoids in which the interior of the isotropy is abelian. We prove that the norms of the images under regular representations, of elements of the reduced groupoid $C^*$-algebra whose supports are contained in the interior of the isotropy vary upper semicontinuously. This corrects an error in [T.M. Carlsen, E. Ruiz, A. Sims and M. Tomforde, "Reconstruction of groupoids and C*-rigidity of dynamical systems," Adv. Math 390 (2021), 107923].

Cough during endobronchial ultrasound (EBUS) is common and can reduce patient comfort, prolong procedures, and compromise diagnostic yield. While dextromethorphan has demonstrated antitussive efficacy, concerns remain regarding side effects and availability. Emblica officinalis (Amla) is a traditional herbal medicine with reported antitussive properties, but human evidence is lacking.

Colorectal cancer (CRC) screening has been recommended for US adults aged 45 to 49 years. This study examined the rate and predictors of CRC screening in 2023 among adults aged 45 to 49 years vs adults aged 50 to 54 years.

Young women undergoing radical mastectomy in China have substantial psychosocial needs, yet equity of access to coordinated psycho-oncology care remains uncertain.
