To investigate the causal relationship between rheumatoid arthritis (RA) and interstitial lung disease (ILD) in the East Asian population, we utilized Mendelian randomization (MR). Publicly available summarized data from genome-wide association studies on RA (4199 cases and 208,254 controls), and the data on ILD (1046 cases and 176,974 controls) were obtained from BioBank Japan. Eligible single nucleotide polymorphisms from East Asian populations were obtained from genome-wide association studies as instrumental variables, and 11 RA-related single nucleotide polymorphisms (P < 5 × 10-8) were selected as instrumental variables. ⋯ The reliability evaluation could adopt the fixed-effect model, and the absolute value of the MR-Egger regression intercept was 0.021, P > 0.05, and P value of Global Test in MR-PRESSO was 0.573. The test results of the leave-one-out showed that the results are robust, and the funnel plot indicated that the instrumental variables were not affected by potential factors. In conclusion, this study demonstrates that RA is a risk factor for ILD in the East Asian population.

Case Reports
Contrast-enhanced computed tomography assisted diagnosis of bleeding caused by colonic angiodysplasia: A case report.
Angiodysplasia (AD) in the gastrointestinal tract is a degenerative vascular condition characterized by vascular dilation, tortuosity, and arteriovenous connections within the mucosal and submucosal layers. AD is a significant cause of lower gastrointestinal bleeding in the elderly, often presenting as chronic, intermittent hemorrhage. The research challenge lies in the potential for multiple and minute AD lesions to be missed during endoscopy, which may lead to post-hemostatic rebleeding. ⋯ We highlight that CECT for diagnosing AD-related bleeding offers higher safety and convenience, potentially superior to digital subtraction angiography, particularly in critically ill elderly patients.

Case Reports
Successful placement of a chest wall venous infusion port via persistent left superior vena cava: A case report.
Persistent left superior vena cava (PLSVC) is a rare congenital venous anomaly occurring in approximately 0.3% to 0.5% of the population. The presence of PLSVC complicates central venous catheter placement, increasing procedural risks. This case report describes the successful placement of a chest wall venous infusion port in a patient with PLSVC, offering valuable insights for managing similar cases and ensuring safer clinical outcomes. ⋯ Detailed preoperative evaluations, intraoperative imaging guidance, and postoperative follow-ups are crucial for the safe and effective management of PLSVC patients undergoing central venous catheter placement.

The ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol, abbreviated as NHHR, represents a brand-new lipid biomarker for assessing cardiovascular disease risk. Research has suggested a link between lipid metabolism and obstructive sleep apnea (OSA). To delve deeper, this study was carried out using data derived from the NHANES to ascertain whether NHHR and OSA are associated. ⋯ Findings from this study uncovered a strong connection between NHHR and an increased possibility of developing OSA in American adults. Further exploration of NHHR could offer insights into OSA prevention and treatment. However, owing to the constraints inherent in cross-sectional studies, more studies are required to establish a concrete link between NHHR and OSA.

Observational Study
Positive association between constipation and mild cognitive impairment in elders: A cross-sectional study.
This study aimed to examine the association between constipation and mild cognitive impairment (MCI); and further elucidate the possible mechanisms involved. A cross-sectional study was conducted among community-dwelling elders (N = 789) in Nanning, China. Trained research staffs collected detailed information through questionnaires and physical examinations. ⋯ Among these, constipation, history of stroke, and years of schooling were directly related to the occurrence of MCI. Years of schooling indirectly affected MCI through infrequent fruit consumption and constipation; or through inactive physical exercises and history of stroke. This study demonstrates a direct association between constipation and increased risks of MCI.
