CA-125 as a Biomarker in Renal Medullary Carcinoma: Integrated Molecular Profiling, Functional Characterization, and Prospective Clinical Validation.

Purpose: Renal medullary carcinoma (RMC) is a highly aggressive malignancy defined by the loss of the SMARCB1 tumor suppressor. It mainly affects young individuals of African descent with sickle cell trait, and it is resistant to conventional therapies used for other renal cell carcinomas. This study aimed to identify potential biomarkers for early detection and disease monitoring of RMC.

Transcriptional responses to prolonged oxidative stress require cholinergic activation of G-protein-coupled receptor signaling.

Organisms have evolved protective strategies that are geared toward limiting cellular damage and enhancing organismal survival in the face of environmental stresses, but how these protective mechanisms are coordinated remains unclear. Here, we define a requirement for neural activity in mobilizing the antioxidant defenses of the nematode both during prolonged oxidative stress and prior to its onset. We show that acetylcholine-deficient mutants are particularly vulnerable to prolonged oxidative stress.

Early Screening for Confusion and Vitamin D Deficiency in Elderly Hip Fracture Patients: A Quality Improvement Initiative to Mitigate the Risk of Postoperative Delirium.

Background Postoperative delirium (POD) is a common and debilitating complication in elderly hip fracture patients, associated with significant clinical and functional consequences. Early identification of risk factors, such as cognitive impairment and vitamin D deficiency, is essential to mitigate its impact. However, preoperative screening practices are often inconsistent.

Proximal Humerus Fractures: A Review of Anatomy, Classification, Management Strategies, and Complications.

Proximal humerus fractures are prevalent in older adults, particularly women, primarily due to osteoporosis and increased fall risk. These fractures often result from low-energy falls in elderly patients, while in younger individuals, they are more likely to occur with high-energy trauma, which may involve additional injuries to soft tissue and neurovascular structures. Proper anatomical understanding, including key structures and blood supply, is crucial for effective management and to prevent complications.

Seroprevalence of HIV, HCV, and HBV: The Associated Psychiatric Co-morbidities Among Injection Drug Users in Kashmir- A Hospital-Based Cross-sectional Study.

Background: Injection drug use remains a significant public health concern globally, with injection drug users (IDUs) facing elevated risks of contracting blood-borne infections such as hepatitis C (HCV), hepatitis B (HBV), and acquired immune deficiency syndrome caused by the human immunodeficiency virus (HIV). This study delves into the seroprevalence of these disorders among IDUs in Kashmir and extends further to explore the relationship between injection drug use and psychiatric co-morbidities.

Methods: A cross-sectional study was conducted among IDUs recruited from tertiary care drug addiction centers.
