Background The correlation between osteoarthritis (OA) and rheumatoid arthritis (RA), both significant components of arthritis, and erectile dysfunction (ED) has yet to be thoroughly investigated. Aim In this study we aimed to assess the association of OA and RA with ED. Methods In this observational study we used data from the National Health and Nutrition Examination Survey, which was conducted between 2001 and 2004. Various statistical analyses were employed to investigate the associations of OA and RA with ED, including multivariable logistic regression analysis and subgroup analysis. Outcomes The primary outcome for this investigation was arthritis as assessed through self-reporting. Results In this comprehensive nationally representative survey spanning 4 years, our findings revealed a notably elevated incidence of ED within both OA and RA populations in comparison to the general population. Additional research is imperative to provide a deeper understanding of these correlations and their potential implications for both pathogenesis and treatment strategies. Clinical Implications The research outcomes reported here may serve as a valuable guide for clinicians to assist OA and RA patientsin staying vigilant in addressing their sexual health concerns. Strengths and Limitations We explored the association of OA and RA with ED. However, this is only a cross-sectional study. Conclusion In this comprehensive nationally representative survey spanning 4 years, our findings revealed a notably elevated incidence of ED within both OA and RA patient populations in comparison to the general population. Ongoing research is imperative to provide a deeper understanding of these correlations. [ABSTRACT FROM AUTHOR]

Objective: The classical approaches for total hip arthroplasty (THA) are the direct lateral approach (DLA) and posterior lateral approach (PLA). There are few studies comparing implant orientation with these two approaches, and the impact of surgical approaches on implant orientation remains controversial. With the rise of the EOS imaging system, we aimed to use it to identify the differences between and factors associated with implant orientation after THA using DLA and PLA. Methods: In our department from January 2019 to December 2021, 321 primary unilateral THAs that used PLA and DLA were enrolled. A total of 201 patients who received PLA and 120 patients who received DLA were included in this study. Two blinded observers measured each case using EOS imaging data. Postoperative imaging metrics and other relevant influencing factors of the two surgical approaches were compared. Postoperative imaging metrics, including the anteversion and inclination of the cup, anteversion of the stem, and combined anteversion were measured based on EOS. Other relevant influencing factors included age, approach, gender, laterality, BMI, anterior pelvic plane inclination, femoral head diameter, femoral offset, lateral pelvic tilt, pelvic incidence, pelvis axial rotation, sacral slope, sagittal pelvic tilt, and surgery time. Multiple linear regression analyses were performed to identify the predictors of acceptability for each imaging data point. Results: No dislocation was found in the 321 patients who underwent primary THA during this period. The mean anteversion and combined anteversion of the cups using the DLA were 21.33° ± 17.31° (−51.7°–60.8°) and 33.71° ± 20.85° (−38.8°–77.6°) and PLA were 25.34° ± 12.76° (−5.5°–57.0°) and 42.37° ± 18.85° (−8.7°–84.7°), respectively. The DLA group had smaller anteversion (p = 0.038) and combined anteversion (p < 0.001). We found that surgical approach (p < 0.05), anterior pelvic plane inclination (p < 0.001), gender (p < 0.001), and femoral head diameter (p < 0.001) were important factors affecting acetabular cup anteversion (R2 = 0.375) and combined anteversion (R2 = 0.525). Conclusions: In total hip arthroplasty, different prosthesis installation directions should be made according to different surgical approaches. Compared with the direct lateral approach, the acetabular anteversion can be intentionally enlarged when using the posterolateral approach. Surgical approach, anterior pelvic plane inclination (APPI), gender, and femoral head diameter were significant predictors of prosthesis orientation. The anterior pelvic plane inclination may be a useful standard for assessing the position of the prosthesis using EOS. [ABSTRACT FROM AUTHOR]

Photoperiod is an essential environmental factor that affects physiological activity and feeding behavior in crustaceans. The current study aimed to investigate the mechanism by which photoperiod influences gut bacterial community composition in the Chinese mitten crab (Eriocheir sinensis). In this study, high-throughput 16S rRNA sequencing was used to identify variations in E. sinensis gut bacteria under three different light: dark conditions (24 L:0 D, 0 L:24 D, and 12 L:12 D). Shannon and Chao1 indexes of community richness and diversity differed significantly between the complete light group and complete dark group on day 4, but these differences disappeared by day 6, suggesting that the gut bacterial community became disrupted on day 4, but adjusted to the new environment by day 6. Tenericutes and Proteobacteria were the dominant phyla under all conditions. Clostridium abundance increased significantly on day 6 under conditions of complete light and complete darkness. These data suggest that the biological clock of E. sinensis minimized changes in gut bacterial community composition under different light conditions. Considering that the gut bacterial community has profound effects on the host, understanding various mechanisms of its influence (including interactions with photoperiod) should be useful for improving E. sinensis aquaculture.

According to the actual situation of Zhejiang Province, an objective and quantitative mathematical model used to assess the tourism index of scenic spots was proposed to extend fine and personalized meteorological services to scenic spots and tourists, in which effects of sunshine, wind power, temperature and relative humidity on the comfort of the human body were considered fully, and warning of weather disasters and occurrence of characteristic meteorological landscapes were also considered. The results show that the comprehensive evaluation index model of tourism has full functions of assessment, has guiding significance to the travel of travel enthusiasts and can provide reference for tourism management.
