Traditional observational studies have reported a positive association between constipation and the risk of colorectal cancer (CRC). However, evidence from other approaches to pursue the causal relationship between constipation and CRC is scarce. In the study, 2-sample Mendelian randomization analysis was conducted to investigate the potential causal relationship between constipation and CRC. ⋯ Also there was no inverse causal association between CRC and constipation, either in European populations (CRC: OR = 0.10, 95% CI = 2.76E-03-3.45, P = .20; rectal cancer: OR = 0.05, 95% CI = 9.14E-07-2.64E + 03, P = .59) or in Asian population (CRC: OR = 1.18, 95% CI = 0.92-1.52, P = .20), there was no horizontal diversity in the instrumental variables in the Mendelian randomization analyses of the present study (all F statistics >10), and no heterogeneity was found in the regression analyses. The findings from bidirectional 2-sample Mendelian randomization analyses indicate that there is no evidence of a bidirectional causal association between constipation and CRC. However, further investigation is warranted through additional clinical studies and trials to thoroughly explore the association between these 2 factors.

Schizophrenia and magnetic resonance imaging research: A scientometric analysis during 2014 to 2023.
Recently, magnetic resonance imaging (MRI) has emerged as a leading technique for investigating schizophrenia (SZ) pathological mechanisms, prompting an increase in related studies. This study aims to examine the field's research status and trends via bibliometric analysis. ⋯ This study offers an overview of the research status and trends of publications on SZ and MRI, aiming to inspire future research directions.

Increasing evidence indicates a significant correlation between gut microbiota (GM) and susceptibility to chronic kidney disease (CKD). However, causal relationship presence remains uncertain. Mendelian randomization (MR) was applied to evaluate potential causal relation from GM to CKD. ⋯ According to the investigation, MR method was employed to delve into reciprocal causal connection from GM to CKD. Our findings identified 15 types of GM causally linked to CKD, as well as CKD demonstrating causal associations with 3 types of GM. Further exploration of these associated GM types is hopeful to raise novel insights, for CKD preventing and early monitoring.

To clarify the causal relationship and potential mediators between educational attainment and carpal tunnel syndrome (CTS), as well as to evaluate whether educational attainment, cognition, and intelligence independently exert causal effects on CTS, we employed univariable Mendelian randomization (MR), multivariable MR, reverse MR, and 2-step MR approaches. Our research demonstrates that educational attainment exerts an independent causal effect on CTS, with this causal relationship being unidirectional. Five mediators were identified as significant influencers within the causal pathways connecting educational attainment and CTS. Targeting these mediators may be beneficial in the prevention of CTS.

Correlation of exercise blood pressure levels with concomitant cardiovascular disease.
Hypertension is a fatal but preventable risk factor for cardiovascular disease and an important cause of death from cardiovascular disease. Exercise training has a definite clinical effect on blood pressure control. However, inappropriate exercise is ineffective and may also cause disease. ⋯ At the same time, the smoking rate and glycohemoglobin level of the patients with abnormal exercise blood pressure were significantly increased (all P < .05), but there was no statistically significant difference in age, sex, body mass index, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and other indicators between the 2 groups (all P > .05). Patients with abnormal exercise blood pressure response have a higher prevalence of hypertension and coronary heart disease. Exercise blood pressure level may be an important factor affecting patients' cardiovascular prognosis.
