Observational studies suggest an association between glioblastoma (GBM) and cardiovascular diseases (CVDs), but a causal relationship remains unestablished. This study aimed to investigate the causal link between multiple CVDs and GBM risk. The inverse variance weighted method indicated that all 18 CVDs had significant causal associations with GBM (P < .05). Genetically predicted CVDs were uniformly associated with a lower risk of GBM (odds ratio < 1), identifying them as potential protective factors. Sensitivity analyses confirmed the absence of significant heterogeneity or horizontal pleiotropy, and the MR-Steiger test validated the correct causal direction. This Mendelian randomization (MR) study provides evidence that a range of CVDs are causally associated with a decreased risk of developing GBM. These findings suggest shared biological pathways and offer new insights for understanding GBM etiology. We conducted a 2-sample MR analysis using publicly available genome-wide association study data. GBM was the outcome, and 18 cardiovascular-related traits (including coronary artery disease, myocardial infarction, and venous thromboembolism) were exposures. Instrumental variables were single-nucleotide polymorphisms significantly associated with exposures (P < 5 × 10-8). The primary analysis used the inverse variance weighted method, supplemented with MR-Egger, weighted median, and weighted mode methods. Sensitivity analyses, including Cochran Q test, MR-Egger intercept test, leave-one-out analysis, and MR-Steiger directionality test, were performed to ensure robustness.
Acquired rectal fistula in human immunodeficiency virus (HIV)-positive children is a new and worrisome entity. The aim of this paper is to highlight the relationship between HIV infection and acquired rectal fistula (RF) in children in order to create awareness among clinicians who attend to children. Over a 1-year period, 11 girls aged 4 weeks-11 months (median 5 months) with acquired RF were managed at our institution. Ten were HIV-positive by enzyme-linked immunosorbent assay and confirmed by Western blot test. One child defaulted before the test. All the mothers and three fathers of the 10 children were seropositive for HIV. Bronchopneumonia, otitis media, oral thrush, diarrhoea, and lymphadenopathy were common associations. Treatment was essentially conservative because the result of surgical intervention was disappointing. Two of the infants and one of the fathers are now dead from full-blown acquired immunodeficiency syndrome. Acquired RF seems to be a sign of HIV infection in children. It will be necessary to screen any child presenting with acquired RF for HIV infection.
