Blastocystis is one of the most common intestinal parasites in humans worldwide. To understand its prevalence and to explore the risk factors for Blastocystis in humans in developing countries, a molecular epidemiological investigation of Blastocystis was conducted in ethnic minority groups on both sides of the China–Myanmar border. A total of 461 fecal specimens were collected from 289 Yao people in China and 172 Wa people in Myanmar, together with a questionnaire for each participant. Based on sequence analysis of the partial small subunit of ribosomal RNA (SSU rRNA) gene (barcode region or 260 bp region), an average prevalence of 6.29% (29/461) was observed, with 4.50% (13/289) in Yao people and 9.30% (16/172) in Wa people. Twenty-two Blastocystis isolates were successfully subtyped by sequence analysis of the barcode region. Three subtypes were identified: ST1 (n = 7), ST3 (n = 13) and ST4 (n = 2). A statistical difference in the prevalence of Blastocystis was only observed between children (12.37%, 12/97) and adults (4.95%, 16/323), and between not washing hands (11.02%, 14/127) and washing hands (4.76%, 15/315) after using toilets, emphasizing the importance and necessity of health education in people in the investigated areas, especially in children.

This study explored the relationships between the decline in sexual function and psychological burdens and life satisfaction in older men with the aim of providing prospective targets for interventions.1,326 men aged over 50 years old. We adopted the International Index of Erectile Function-5 (IIEF-5), self-estimated intravaginal ejaculatory latency time (IELT), the premature ejaculation diagnostic tool (PEDT), the General Anxiety Disorder-7 (GAD-7), the Patients Health Questionnaire-9 (PHQ-9), the satisfaction with life scale and the control, autonomy, self-realisation and pleasure scale (CASP-19) to measure premature ejaculation, erectile dysfunction and well-being (including, depression, anxiety, and life quality and satisfaction) respectively. The individuals were divided into two main groups: the decline group and the no-decline group. The incidences of erectile dysfunction (ED), premature ejaculation (PE), anxiety and depression in men who reported a decline in sexuality were 73.83% (330/447), 63.98% (286/447), 75.84% (339/447) and 68.46% (306/447) respectively. Men who showed a decline in sexuality had significantly worse psychological and life satisfaction/quality scores than those in the no-decline group (p < .001 for all). When they had PE or ED simultaneously, these differences widened. Significantly worsened psychological status and life quality/satisfaction scores could be observed in patients who had declined sexual desire and declined frequency of sex (p < .001 for both). Under the impact of the decline in sexual function, the younger participants (age < 60) had significantly worsened negative emotions and life quality and satisfaction. Based on the results of the study, we found that the decline in sexuality was associated with depression and anxiety and worse life satisfaction and quality. Clinicians need to pay more attention to psychological status and life satisfaction and quality for those patients affected by a decline in sexuality.

Delftia tsuruhatensis has become an emerging pathogen in humans. There is scant information on the genomic characteristics of this microorganism. In this study, we determined the complete genome sequence of a clinical D. tsuruhatensis strain, TR1180, isolated from a sputum specimen of a female patient in China in 2019. Phylogenetic and average nucleotide identity analysis demonstrated that TR1180 is a member of D. tsuruhatensis. TR1180 exhibited resistance to β-lactam, aminoglycoside, tetracycline and sulphonamide antibiotics, but was susceptible to phenicols, fluoroquinolones and macrolides. Its genome is a single, circular chromosome measuring 6,711,018 bp in size. Whole-genome analysis identified 17 antibiotic resistance-related genes, which match the antimicrobial susceptibility profile of this strain, as well as 24 potential virulence factors and a number of metal resistance genes. Our data showed that Delftia possessed an open pan-genome and the genes in the core genome contributed to the pathogenicity and resistance of Delftia strains. Comparative genomics analysis of TR1180 with other publicly available genomes of Delftia showed diverse genomic features among these strains. D. tsuruhatensis TR1180 harbored a unique 38-kb genomic island flanked by a pair of 29-bp direct repeats with the insertion of a novel In4-like integron containing most of the specific antibiotic resistance genes within the genome. This study reports the findings of a fully sequenced genome from clinical D. tsuruhatensis, which provide researchers and clinicians with valuable insights into this uncommon species.

Background Diet, one of the components of lifestyle, has been believed to have associations with erectile dysfunction (ED). However, whether there is an association between plant-based diet and ED is remains to be explored. Thus, we conducted the nested case-control study to investigate the relationship between the plant-based diet and ED in China. Results ED group (92 subjeczts) and ED free group (92 subjects) were similar in terms of basic features (P > 0.05), except for lifestyle (P < 0.05). The plant-diet index (PDI) and healthy plant-diet index (hPDI) in the ED group were significantly lower than those in the control group (P < 0.001). Adjusted multivariate analysis indicated that the presence of ED was negatively associated with nitric oxide levels, PDI, and hPDI (all P < 0.05), and was positively related to body mass index, metabolic syndrome, and E-selectin levels. Furthermore, both the PDI and hPDI increased significantly as the International Index of Erectile Function (IIEF-5) scores increased within the ED group (P < 0.05). Multi-model multivariate analysis indicated the robustness of results. Conclusions More plant-based diet intake was associated with a reduced presence of ED and less severe ED in China. Committing to plant-based diet can be encouraged for many health benefits and to lower ED burden. Further well-designed studies are warranted to validate our findings.

Background: Non-muscle invasive bladder cancer accounts for nearly 80% of newly diagnosed bladder cancer cases, which often recur and progress. This meta-analysis was evaluated by the adverse events and recurrence rate of thermal intravesical chemotherapy vs. normal temperature intravesical chemotherapy in the treatment of non-muscle invasive bladder cancer. Methods: A systematic review and cumulative analysis of studies reporting adverse events and recurrence rate of thermal intravesical chemotherapy vs. normal temperature intravesical chemotherapy was performed through a comprehensive search of Pubmed, Embase, Cochranelibrary.com, CNKI, Wanfang Med Online database and VIP database. All analyses were performed using the Revman manager 5. Result: Twelve studies (11 randomized controlled trials and 1 retrospective study) including 888 patients, 445 in the thermal intravesical chemotherapy group, and 443 in the normal temperature intravesical chemotherapy group, met the eligibility criteria. Patients in the thermal intravesical chemotherapy group had a lower risk of disease recurrence than those who had normal temperature intravesical chemotherapy (24 months follow-up group: RR = 0.30, 95% CI: 0.21-0.43, P < 0.00001, I 2 = 0%; 36 months follow-up group: RR = 0.27, 95% CI: 0.14-0.54, P = 0.0002, I 2 = 0%) while no significant difference in adverse events rate (RR = 0.89, 95% CI = 0.53-1.52; P = 0.67, I 2 = 78%). Conclusions: When compared with normal temperature intravesical chemotherapy, thermal intravesical chemotherapy can reduce the recurrence rate without increasing incidence of adverse events in patients with non-muscle invasive bladder cancer.
