The Bidirectional Relationship Between Type 2 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease: A Retrospective Cohort Study.

Introduction Type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD) have shared pathophysiology. We aim to explore associations between these diseases and the impact of T2D therapies on MASLD-related outcomes in a real-world population. Methods A retrospective cohort study included 153 patients with biopsy-proven MASLD.

Lower Urinary Tract Symptoms in Relation to Leiomyoma Volume, Location, and Position in Reproductive-aged Women in the USA.

Introduction And Hypothesis: Uterine leiomyomata are widely believed to contribute to lower urinary tract symptoms in women, but it is unclear whether leiomyoma size, position, and location have important implications for these symptoms. We assessed whether greater leiomyoma volume, anterior position, and subserosal location were associated with urinary incontinence and frequent urination in a racially diverse, nationwide sample of premenopausal women in the USA.

Methods: A cross-sectional analysis of 477 premenopausal women from 12 USA sites undergoing evaluation for laparoscopic radiofrequency ablation or myomectomy for leiomyomata was carried out.

Antibiotic resistance gene levels within a highly urbanised estuary.

Antibiotic resistant bacteria are increasingly being found in aquatic environments, representing a potential threat to public health. To examine the dynamics and potential sources of antibiotic-resistant genes (ARGs) in urbanised waterways, we performed a six-month temporal study at six locations within the Sydney Harbour estuary. These locations spanned a salinity gradient from seawater at the mouth of the harbour to freshwater at the more urbanised western sites.

Prolonged persistence of mutagenic DNA lesions in somatic cells.

DNA is subject to continual damage, leaving each cell with thousands of individual DNA lesions at any given moment. The efficiency of DNA repair means that most known classes of lesion have a half-life of minutes to hours, but the extent to which DNA damage can persist for longer durations remains unknown. Here, using high-resolution phylogenetic trees from 89 donors, we identified mutations arising from 818 DNA lesions that persisted across multiple cell cycles in normal human stem cells from blood, liver and bronchial epithelium.
