Background: Testosterone deficiency (TD) is a prevalent condition that negatively impacts health, with diet quality being a potential modifiable risk factor. Using cross-sectional NHANES 2011-2016 data, we evaluated the association between diet quality and TD.

Methods: This cross-sectional study analyzed 3262 male adults aged ≥20 years from NHANES (2011-2016). Diet quality was assessed using the Healthy Eating Index (HEI-2020) and the Comprehensive Dietary Antioxidant Index (CDAI). Logistic regression analysis was performed to assess the association between diet quality and TD.

Results: Participants with TD had significantly lower HEI-2020 scores compared to non-TD participants (48.64 vs. 49.38, p = 0.038). In the fully adjusted model (age, race, BMI, etc.), participants in the highest tertile of CDAI had a significantly lower risk of TD (OR = 0.85, 95% CI: 0.76-0.96, p = 0.014). After adjusting for potential confounders (age, race, BMI, etc.), individuals in the highest tertile of HEI-2020 also showed a reduced odds of TD (OR = 0.87, 95% CI: 0.77-0.98, p = 0.011).

Conclusions: Better adherence to diet quality indices, as measured by HEI-2020 and CDAI, is associated with a lower risk of TD.

Background: Exercise prescription can promote the rehabilitation of patients with prostate cancer (PCa). However, the effect of exercise intervention onserum levels of prostate-specific antigen (PSA) and testosterone remains unclear.

Methods: The primary outcome was the effect of exercise prescription on PSA level. The secondary outcome was the effect of exercise training on testosterone level. The pooled standardized mean difference (SMD) with 95% confidence interval (CI) was selected as the indicator. Meta-regression was conducted to assess the relationship between covariates and outcomes. Publication bias was evaluated using funnel plots and Egger's test.

Results: The data of 594 patients from 8 randomized controlled trials (RCTs) were included and analyzed. Pooled effect of exercise intervention on PSA was 0.13 (95% CI: -0.04 to 0.29, I² = 0.0%, p = 0.984), while the pooled effect on testosterone was 0.19 (95% CI: -0.00 to 0.39, I² = 0.0%, p = 0.435). The meta-regression showed there was no significant association of age, body mass index, and the exercise duration with PSA or testosterone. No significant publication bias was detected in meta-analysis.

Conclusions: Although many benefits were documented, exercise intervention have no significant effect on PSA and testosterone levels in PCa patients.

Background: Clinical observational studies have demonstrated a high prevalence of obstructive sleep apnea (OSA) in patients with atrial fibrillation (AF), indicating a significant comorbidity between the two conditions. This study applies transcriptome data to investigate shared molecular mechanisms underlying AF and OSA comorbidity and develops a robust diagnostic model to evaluate OSA risk in AF patients.

Methods: Transcriptomic datasets for AF (GSE79768) and OSA (GSE135917) were retrieved from the the Gene Expression Omnibus(GEO) database. Differentially expressed genes (DEGs) associated with OSA and AF comorbidity were identified using weighted gene co-expression network analysis (WGCNA). Protein-protein interaction (PPI) networks were constructed using Cytoscape, and hub genes were identified with the CytoHubba plug-in. A diagnostic model was then built based on these hub genes, and its performance was evaluated using receiver operating characteristic (ROC) curves in both the test and validation datasets. Immune cell infiltration analysis was conducted using CIBERSORT.

Results: A total of 1,462 differentially expressed genes (DEGs) were identified for the comorbidity of AF and OSA. Five hub genes were selected: IFNG, IL4, IL15, CD19, and FASLG. Immunoassay infiltration analysis revealed elevated levels of activated macrophages in both OSA and AF samples. The diagnostic model we developed demonstrated excellent predictive performance in the validation set.

Conclusion: We identified five hub genes common to both OSA and AF: IFNG, IL4, IL15, CD19, and FASLG. Moreover, a diagnostic model based on these five hub genes can predict the risk of OSA in patients with AF.

Background: In the elderly, diagnosing and treating functional dyspepsia may be more challenging. The objectives of the study were to evaluate the prevalence and association of functional dyspepsia in adult individuals and elderly populations (especially ≥64 years) in the year 2024-2025 literature available.

Methods: The study included a search of electronic articles, electronic books, and electronic book chapters using the keywords "dyspepsia" and "age" in PubMed, PubMed Central, and Google.

Results: A total of 27.5 ± 21.39%, 24.8 ± 21.86%, 23.83 ± 23.54%, 23.5 ± 25.06%, and 21.9 ± 24.63% are reported prevalence of dyspepsia in all study populations (1-100 years; 23 articles), for patients ≥50 years (20 articles), for patients >55 years (15 articles), for patients ≥64 years (15 articles), and for patients >70 years (12 articles), respectively. Mostly gastric symptoms, specific treatments, older age, and female gender were associated with functional dyspepsia.

Conclusions: One in four individuals in every age group has functional dyspepsia among the included patients (25% of patients). The study reported a 23.5 ± 25.06% prevalence of functional dyspepsia for ≥64 years patients regardless of the definition used. Helicobacter pylori infection, specific treatments, female gender, poorer sleep quality, and smoking are independent factors for the prevalence of functional dyspepsia in ≥64 years patients.

Aims: Epidemiological studies indicate a heightened risk of pancreatic adenocarcinoma (PAAD) in patients with type 2 diabetes mellitus (T2DM). This study investigates the molecular mechanisms underlying their comorbidity.

Materials and methods: Common DEGs between T2DM and PAAD were identified from GEO datasets. Functional and pathway enrichment analyses were performed via PPI, GO, and KEGG. Core genes were screened and their diagnostic value was validated by ROC curves. Immune infiltration and TF-mRNA-miRNA regulatory networks were constructed to explore disease mechanisms. Core gene expression and prognostic significance in PAAD were assessed using GEPIA2 and HPA. Potential therapeutics targeting core genes were predicted via the Therapeutic Target Database.

Results: A total of 35 DEGs were identified. GO analysis linked these genes to cell adhesion and extracellular matrix (ECM) components. KEGG enrichment highlighted ECM-receptor interaction as the top pathway. Key ECM-related molecules-ITGA3, FN1, LAMB3, ITGA2, and LAMC2-were upregulated in both T2DM and PAAD. Six potential therapeutic agents targeting ITGA2, LAMB3, and FN1 were identified.

Conclusion: Three genes and associated known drugs identified in this study may serve as potential targets for treating the coexistence of the two diseases.

Purpose: This study evaluates the effectiveness of artificial urinary sphincter (AUS) implantation following transperineal reanastomosis in men with vesicourethral anastomotic stenosis (VUAS) and stress urinary incontinence (SUI) after radical prostatectomy (RP), focusing on long-term explantation rates and urinary continence.

Methods: Patients treated between 2009 and 2020 were retrospectively analyzed. Those undergoing AUS implantation post-transperineal reanastomosis for recurrent VUAS, excluding cases with prior pelvic irradiation and overactive bladder, were included. Primary outcomes were AUS explantation rates and patient-reported continence. Median follow-up was calculated using reverse Kaplan-Meier estimates, and explantation-free survival illustrated via Kaplan-Meier analyses.

Results: At final follow-up, 19 patients were included at a median follow-up of 79 months. Explantation occurred in 16% (N = 3) of cases, with a median time to explantation of 107 months. No urethral erosion was observed. Explantation-free survival at 2, 5, and 10 years was 100%, 87%, and 73%, respectively. The median number of pads/day decreased significantly postoperatively, with 78% (N = 14) reporting subjective continence and 89% (N = 16) achieving social continence.

Conclusion: AUS implantation following transperineal reanastomosis for VUAS post-RP offers favorable long-term outcomes, with low explantation rates and no erosion, making it a viable management strategy.

Objectives: This study aimed to elucidate the correlation of Visceral Adiposity Index (VAI) with prostate cancer (PCa) among men aged 40 years and older in the United States.

Methods: Analysis included multivariate linear and logistic regression, smoothing curve fitting, and threshold effect evaluation using 2003-2010 National Health and Nutrition Examination Survey (NHANES) data. The stability of this relationship across demographic groups was assessed via subgroup analyses and interaction tests.

Results: Among 2,768 participants, those with elevated VAI displayed lower total prostate-specific antigen (tPSA) levels and reduced PCa risk. Each VAI unit elevation corresponded to a 0.075 ng/mL tPSA reduction [-0.075 (-0.145, -0.005)] and 18.8% PCa risk reduction [0.812 (0.687, 0.960)]. Top-quartile VAI individuals exhibited 0.282 ng/mL reduced tPSA [-0.282 (-0.557, -0.007)] and 49.7% reduced PCa risk [0.503 (0.282, 0.896)] relative to bottom-quartile counterparts. This inverse relationship was more pronounced in men ≥70 years. Moreover, VAI-tPSA in other races demonstrated a U-shaped pattern, with a 2.09 inflection point. At the same time, a Mexican American subgroup exhibited an inverted U-shape for VAI and PCa risk, with a 1.42 inflection point.

Conclusion: In men aged ≥70, VAI indicates an inverse PCa relationship. However, PSA-based PCa screening may be influenced in visceral-obese individuals aged <70.

Background: Benign prostatic hyperplasia (BPH) is a common condition that affects elderly men, but its relationship with central obesity in the American population has not been adequately elucidated.

Methods: In this study, we included a total of 4,625 participants from the National Health and Nutrition Examination Survey (NHANES) database spanning from 2001 to 2008. We calculated indices related to central obesity for each participant and then employed univariate logistic regression, multivariate logistic regression, restricted cubic splines (RCS), and Akaike's Information Criterion (AIC) analysis.

Results: we found that the indices of Weight, Waist Circumference (WC), waist-to-Height Ratio (WHtR), and Body Roundness Index (BRI) were significantly elevated in the BPH group. In terms of dietary intake, we found that the intake of total fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, and cholesterol was significantly higher in the BPH group, with polyunsaturated fatty acids and cholesterol meeting the criteria for both univariate and multivariate regression analyses.

Conclusion: Weight, WC, WHtR, and BRI can effectively improve the prediction of BPH, which may be associated with the high intake of polyunsaturated fatty acids and cholesterol. Appropriately adjusting the types and total amount of fat intake may prevent the occurrence of prostatic hyperplasia.
