Proctological disorders: psychometrics assessment of personality features and clinical evaluation

Sport practice and hemorrhoidal disease: results from a self-assessment questionnaire among athletes

BACKGROUND

Hemorrhoidal disease (HD) is a common proctologic disease. Dietary and lifestyle play a role in the genesis of the disease or in its progression to more severe forms, although the exact mechanism is still not fully understood. We performed a pilot observational cross-sectional analytical association study to evaluate the possible association between sport activities and HD.

METHODS

We included subjects aged 18 years old or more, competitive and non-competitive, practicing at least one sport activity, at least twice a week. Data were collected using an online questionnaire, developed on the Microsoft Teams communication platform.

RESULTS

Out of the 312 study participants, 34% reported HD. Among subjects who practiced cycling or horseback riding, 57% reported suffering from HD; among those practicing bodybuilding, 48% complained of HD. In the multivariate logistic regression analysis, age and bodybuilding practice showed a statistically significant association with HD.

CONCLUSIONS

Some sport activities could play a role in the onset or worsening of HD. Our results showed a positive association between cycling, horseback riding, bodybuilding, and HD occurrence. Given the numerous health benefits of physical activity, patients should be provided with correct information regarding the practice of sports in relation to their pathology.

Shared genetic architecture of psychiatric disorders and hemorrhoidal disease: a large-scale genome-wide cross-trait analysis

Background

The genetic association between psychiatric disorders and hemorrhoidal disease (HEM) is still not well known. The work aims to investigate their comorbidity at a genetic level.

Methods

Utilizing recent large-scale genome-wide association studies (GWAS), we investigated the genetic overlap at the single nucleotide polymorphism (SNP), gene, and molecular level between depression and HEM, bipolar disorder (BD) and HEM, neuroticism and HEM, as well as schizophrenia (SCZ) and HEM. The cross-trait genes were validated through the utilization of transcriptome and proteome methodologies. The causal link was assessed using bidirectional two-sample Mendelian randomization analysis (MR) analysis. MRlap corrects for the potential bias in estimation caused by sample overlap.

Results

We discovered significant positive genetic associations between these four types of psychiatric disorders and HEM. Cross-phenotypic association analyses identified shared SNPs along with 17 specific loci between psychiatric disorders and HEM. MAGMA identified a total of 2304 pleiotropic genes, several of which showed significant expression in the results of transcriptome and proteome analyses. We observed that these genes are mostly associated with the regulation of transcription factors and particular DNA binding activities. Lastly, MR analysis provided evidence supporting a correlation between these conditions.

Conclusion

This study revealed a genetic correlation between four psychiatric disorders and HEM, identified pleiotropic loci, found multiple candidate genes, and confirmed causal relationships. This has enhanced our comprehension of the common genetic mechanisms of psychiatric disorders and HEM.
