Background: To identify the risk factors associated with rebleeding in obscure gastrointestinal bleeding (OGIB) patients from southern China.
Methods: This retrospective study involved 229 patients who underwent small bowel endoscopy in our hospital between 1 January 2018 and 1 December 2020. The clinical characteristics and risk factors related to rebleeding were retrospectively evaluated.
Results: Rebleeding patients were significantly older than non-rebleeding patients (53.0 ± 15.9 46.2 ± 17.8 years), had lower hemoglobin concentrations (89.2 ± 28.1 126.2 ± 25.1 g/L), and higher blood urea nitrogen concentrations (5.4 ± 2.6 4.5 ± 2.2 µmol/L), respectively. A higher percentage of rebleeding patients had diabetes mellitus (13.9% 2.9%) and overt bleeding (70.4% 38.6%), and required blood transfusions (43.1% 8.0%), compared with non-rebleeding patients, respectively. Multivariate logistic analysis indicated that drinking alcohol (odds ratio (OR): 9.27; 95% confidence interval (CI) = 1.35-63.78), anemia (OR: 17.38; 95% CI = 5.48-55.10), and blood transfusion (OR: 3.76; 95% CI = 1.04-13.56) increased the risk of rebleeding in OGIB patients.
Conclusion: Our data suggested that OGIB patients who drink alcohol, have anemia, and require blood transfusion have an increased risk of rebleeding.

Understanding the Importance of the Small Artery Media-Lumen Ratio: Past and Present.
Basic Clin Pharmacol Toxicol
February 2025
Department of Biomedicine, Aarhus University, Aarhus, Denmark.
The media-lumen diameter ratio of small arteries is increased in hypertension, diabetes and obesity. It is likely that both shear stress on the endothelial cells, transmural pressure and smooth muscle cell tone are important for the altered vascular structure. However, the precise interaction and importance of these factors are incompletely understood.

Division of Endocrinology and Metabolism, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.
Background: There are insufficient studies to determine whether sodium-glucose cotransporter type 2 inhibitors (SGLT2i) will help reduce early diabetic cardiomyopathy, especially in patients without documented cardiovascular disease.
Methods: We performed a single center, prospective observation study. A total of 90 patients with type 2 diabetes patients without established heart failure or atherosclerotic cardiovascular disease were enrolled.

Department of Epidemiology and Biostatistics, Tbilisi State Medical University, Tbilisi, Georgia.
Background: Childhood overweight and obesity are significant global public health challenges that affect approximately 340 million children worldwide. In Georgia, the prevalence of childhood obesity is alarming, with approximately 28% of 7-year-old children classified as overweight or obese in 2019. This study aimed to investigate the key factors associated with overweight and obesity among school-age children in Georgia.

Faculty of Medicine and Health Sciences, McGill University, Montreal, Canada.
Background: The integration of procedure-specific risks into preoperative patient assessment and optimization are crucial aspects of perioperative care. However, data on internists' knowledge of surgical and anesthetic principles and practices are limited. We thus sought to identify internists' knowledge gaps in terms of surgical- and anesthetic-specific risk factors and characteristics.
