Purpose:
Erectile dysfunction (ED) is a common male sexual dysfunction. Gut microbiota plays an important role in various diseases. To investigate the effects and mechanisms of intestinal flora dysregulation induced by high-fat diet (HFD) on erectile function.
Materials and Methods:
Male Sprague–Dawley rats aged 8 weeks were randomly divided into the normal diet (ND) and HFD groups. After 24 weeks, a measurement of erectile function was performed. We performed 16S rRNA sequencing of stool samples. Then, we established fecal microbiota transplantation (FMT) rat models by transplanting fecal microbiota from rats of ND group and HFD group to two new groups of rats respectively. After 24 weeks, erectile function of the rats was evaluated and 16S rRNA sequencing was performed, and serum samples were collected for the untargeted metabolomics detection.
Results:
The erectile function of rats and the species diversity of intestinal microbiota in the HFD group was significantly lower, and the characteristics of the intestinal microbiota community structure were also significantly different between the two groups. The erectile function of rats in the HFD-FMT group was significantly lower than that of rats in the ND-FMT group. The characteristics of the intestinal microbiota community structure were significantly different. In the HFD-FMT group, 27 metabolites were significantly different and they were mainly involved in the several inflammation-related pathways.
Conclusions
Intestinal microbiota disorders induced by HFD can damage the intestinal barrier of rats, change the serum metabolic profile, induce low-grade inflammation and apoptosis in the corpus cavernosum of the penis, and lead to ED.

In recent years, with the clinical application of minimally invasive surgical techniques and comprehensive preoperative treatment, the survival rate of locally advanced esophageal cancer has significantly improved. However, the treatment of metastatic esophagogastric cancer still relies mainly on systemic therapy, and immunotherapy combined with chemotherapy has become a first-line treatment option, prolonging the survival of patients with metastatic esophageal cancer. Oligometastatic esophageal cancer is expected to bring survival benefits through systemic therapy combined with local treatment. The 2024 European clinical practice guidelines for oligometastatic esophagogastric cancer have been officially released, which standardize the definition, diagnosis, and treatment of oligometastatic esophageal cancer for further prospective studies. The authors interpret this guideline, especially by reviewing the clinical evidence of oligometastatic esophageal squamous cell carcinoma, to provide reference for the diagnosis and treatment of oligometastatic esophageal cancer in China.

Objective To analyze the epidemic characteristics of pneumoconiosis in Jingmen City from 2011 to 2022, and to provide theoretical basis for formulating the occupational disease prevention plan of the “14th Five-Year Plan” in Jingmen City. Methods The data of pneumoconiosis cases in Jingmen City from 2011 to 2022 were collected from the Occupational Disease and Health Hazard Factors Monitoring Information System, and the information of disease classification, enterprise economic type, scale distribution, regional distribution, job distribution, dust exposure years and so on was statistically analyzed. Results A total of 260 cases of pneumoconiosis were reported in Jingmen City from 2011 to 2022, with an average of 13.81 years of exposure to dust, including 164 cases of coal workers' pneumoconiosis, 90 cases of silicosis and 6 cases of other pneumoconiosis. The cases were mainly distributed in Dongbao District with 160 cases (61.54%), Zhongxiang City with 72 cases (27.69%), and Duodao District with 18 cases (6.92%). The difference was statistically significant(χ2=217.846,P<0.05). The cases were mainly distributed in private enterprises (76.54%, 199 cases). The enterprise sizes were mainly medium-sized (28.46%, 74 cases) and small (61.15%, 159 cases) enterprises, and the difference was statistically significant (χ2=46.025,P<0.05). Conclusion Coal workers' pneumoconiosis and silicosis are the main types of occupational pneumoconiosis in Jingmen area, which will become the key prevention and control targets in Jingmen City for a long time and should be paid attention to. The cases are mainly concentrated in joint-stock, private economic type enterprises and small and medium-sized enterprises, which should be monitored intensively.

The World Journal of Men's Health 2024;42(2):363-372
Purpose:
Little is known about the role of gut microbiota in the pathogenesis of erectile dysfunction (ED). We performed a study to compare taxonomic profiles of gut microbiota of ED and healthy males.
Materials and Methods:
A total of 43 ED patients and 16 healthy controls were enrolled in the study. The 5-item version of the International Index of Erectile Function (IIEF-5) with a cutoff value of 21 was used to evaluate erectile function. All participants underwent nocturnal penile tumescence and rigidity test. Samples of stool were sequenced to determine the gut microbiota.
Results:
We identified a distinct beta diversity of gut microbiome in ED patients by unweighted UniFrac analysis (R2=0.026, p=0.036). Linear discriminant analysis effect size (LEfse) analysis showed Actinomyces was significantly enriched, whereas Coprococcus_1, Lachnospiraceae_FCS020_group, Lactococcus, Ruminiclostridium_5, and Ruminococcaceae_UCG_002 were depleted in ED patients. Actinomyces showed a significant negative correlation with the duration of qualified erection, average maximum rigidity of tip, average maximum rigidity of base, tip tumescence activated unit (TAU), and base TAU. Coprococcus_1, Lachnospiraceae_FCS020_group, Ruminiclostridium_5, and Ruminococcaceae_UCG_002 were significantly correlated with the IIEF-5 score. Ruminiclostridium_5 and Ruminococcaceae_UCG_002 were positively related with average maximum rigidity of tip, average maximum rigidity of base, ΔTumescence of tip, and Tip TAU. Further, a random forest classifier based on the relative abundance of taxa showed good diagnostic efficacy with an area under curve of 0.72.
Conclusions
This pilot study identified evident alterations in the gut microbiome composition of ED patients and found Actinomyces was negatively correlated with erectile function, which may be a key pathogenic bacteria.

Purpose:
Whether COVID-19 reduces male fertility remains requires further investigation. This meta-analysis and systematic review evaluated the impact of COVID-19 on male fertility.
Materials and Methods:
The literature in PubMed, Embase, MEDLINE, Web of Science, and Cochrane Library up to January 01, 2022 was systematically searched, and a meta-analysis was conducted to investigate the effect of COVID-19 on male fertility. Totally 17 studies with a total of 1,627 patients and 1,535 control subjects were included in our meta-analysis.
Results:
Regarding sperm quality, COVID-19 decreased the total sperm count (p=0.012), sperm concentration (p=0.001), total motility (p=0.001), progressive sperm motility (p=0.048), and viability (p=0.031). Subgroup analyses showed that different control group populations did not change the results. It was found that during the illness stage of COVID-19, semen volume decreased, and during the recovery stage of COVID-19, sperm concentration and total motility decreased <90 days. We found that sperm concentration and total motility decreased during recovery for ≥90 days. Fever because of COVID-19 significantly reduced sperm concentration and progressive sperm motility, and COVID-19 without fever ≥90 days, the sperm total motility and progressive sperm motility decreased. Regarding disease severity, the moderate type of COVID-19 significantly reduced sperm total motility, but not the mild type. Regarding sex hormones, COVID-19 increased prolactin and estradiol. Subgroup analyses showed that during the illness stage, COVID-19 decreased testosterone (T) levels and increased luteinizing hormone levels. A potential publication bias may have existed in our meta-analysis.
Conclusions
COVID-19 in men significantly reduced sperm quality and caused sex hormone disruption. COVID-19 had long-term effects on sperm quality, especially on sperm concentration and total motility. It is critical to conduct larger multicenter studies to determine the consequences of COVID-19 on male fertility.
