Scoliosis, marked by abnormal spinal curvature, is common in adolescents and can lead to chronic pain and reduced quality of life. The relationship between physical activity and scoliosis is debated. In this study, we aim to investigate the causal relationship between physical activity levels and idiopathic scoliosis risk using the Mendelian randomization (MR) approach. ⋯ Total physical activity emerges as an idiopathic scoliosis risk factor, warranting mechanistic exploration. LIPA and MVPA do not causally link to scoliosis. Idiopathic scoliosis does not influence activity levels.

Observational studies have reported an association between Vitamin D deficiency and an increased risk of bronchiectasis. This study aims to investigate the causal relationship between Vitamin D levels and bronchiectasis using a 2-sample Mendelian randomization (MR) analysis. Data from 2 genome-wide association studies (GWAS) based on European ancestry were analyzed: serum vitamin D levels (sample size = 441,291 [UK Biobank]) and bronchiectasis (sample size = 187,830 [cases = 1107, controls = 186,723; FinnGen]). ⋯ Additionally, no evidence supported the causal effects of bronchiectasis on serum vitamin D levels (β = -0.002, 95% CI: -0.007 to 0.003; P = .463). Our study found no significant causal association between serum 25(OH)D levels and bronchiectasis, in either direction. A larger sample-sized randomized controlled trial (RCT) is needed to further investigate this potential causal relationship.

Autophagy is a cellular process in which damaged organelles or unnecessary proteins are encapsulated into double-membrane structures and transported to lysosomes for degradation. Autophagy plays a crucial role in various liver diseases, including nonalcoholic fatty liver disease. This study aims to elucidate the role of autophagy in nonalcoholic fatty liver disease through bibliometric analysis. ⋯ Research on autophagy in nonalcoholic fatty liver disease is still in its early stages, with a growing body of literature. This study is the first to provide a comprehensive bibliometric analysis, synthesizing research trends and advancements. It identifies current development trends, global cooperation models, foundational knowledge, research hotspots, and emerging frontiers in the field.

Sleep is a vital restorative process that plays a pivotal role in maintaining the delicate equilibrium of mental and physical well-being. Both short and long sleep duration are associated with a range of adverse health outcomes. Numerous studies have consistently demonstrated a robust association between sleep duration and liver disease. ⋯ Using a two-segment linear regression model, we found an U-shaped relationship and significant inflection point between between ALT and AST with sleep duration. The present study unveiled a significant inverse correlation between sleep duration and levels of ALT and AST, while no significant association was observed with TB levels. Furthermore, variations in the optimal sleep duration for liver function recovery were identified across diverse populations, thereby offering valuable healthcare recommendations to public.

There is currently insufficient research on the causal relationship between depression and constipation. This study aims to provide clear evidence for the positive and negative causal relationship between depression and constipation through bidirectional two-sample Mendelian randomization (MR) analysis. MR is a statistical method used to evaluate the credible causal relationship between exposure and outcomes. ⋯ There is no heterogeneity in the impact of depression on constipation in the bidirectional analysis results, and there is heterogeneity in the impact of constipation on depression, but there is no horizontal pleiotropy. Our bidirectional two-sample MR analysis identified a causal relationship between depression and constipation. This discovery may help clinical doctors to intervene in depression patients in a timely and effective manner when treating constipation patients, avoiding further deterioration of the condition.
