Distinct genetic risk loci between biopsy-proven renal and non-renal lupus: a 10-year longitudinal cohort.

Objective: Systemic lupus erythematosus (SLE) is a heterogeneous disease which manifests as different subphenotypes. Distinct subphenotypes, such as lupus nephritis (LN), have been associated with increased genetic risk, but prior studies have been limited by cross-sectional and imprecisely subphenotyped cohorts. This study investigated the genetic basis for LN using a longitudinal cohort of distinctly subphenotyped patients.

Cost-effectiveness of robotic mastectomy vs. conventional mastectomy: A long-term economic evaluation from a Singapore healthcare perspective.

Importance: Breast cancer is the most prevalent cancer among women globally, and Singapore is no exception. Surgical intervention, especially mastectomy, is a cornerstone of breast cancer treatment. While conventional mastectomy (CM) has been the gold standard, robotic mastectomy (RM) has emerged as a promising alternative due to its minimally invasive nature.

Idiopathic Coronary Sinus Thrombosis.

A 62-year-old man with acute coronary syndrome underwent an echocardiogram for evaluation. A transthoracic echocardiogram revealed masses within a giant coronary sinus. This case highlights the role of multimodality imaging in investigating coronary sinus enlargement, coronary sinus thrombosis, and the approach to management.

Fetal Cartilage Progenitor Cells in the Repair of Osteochondral Defects.

Background: Therapies for cartilage restoration are of great interest, but current options provide limited results. In salamanders, interzone (IZN) tissue can regenerate large joint lesions. The mammalian homolog to this tissue exists during fetal development and exhibits remarkable chondrogenesis in vitro.
