Objective:
This study aimed to systematically evaluate potential causal relationships between nine cathepsins and female infertility using Mendelian randomization (MR) methods.
Methods:
A bidirectional MR analysis was conducted utilizing single nucleotide polymorphisms as instrumental variables to investigate the potential causal effects between nine cathepsins and female infertility. Genetic data on female infertility were sourced from the FinnGen study, and cathepsin-related data were obtained from genome-wide association studies datasets of European ancestry.
Results:
Elevated levels of cathepsin E were significantly and inversely associated with the risk of female infertility, suggesting a potential protective role. This finding was further supported by multivariable MR analysis. However, no significant associations were observed between the other eight cathepsins and female infertility.
Conclusion
This study represents the first systematic MR analysis to identify a potential protective effect of cathepsin E on female infertility.

OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii (CRAB) pulmonary infection. METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024. Information such as age, gender, admitting department, infection status, underlying medical conditions, mechanical ventilation time, combination anti-infective treatment regimens, and the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE-Ⅱ) score 24 h before medication was compiled. Based on the effectiveness of the treatment, patients were divided into treatment-effective group and treatment-ineffective group. Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy. RESULTS A total of 156 patients were included, and 108 patients were treated effectively, with an effective rate of 69.23%. The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time, APACHE-Ⅱ score 24 h before medication, the number of complication types, the proportion of abnormal coagulation function, anti-infective treatment course, and hospital stay before medication (P<0.05). The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication [OR=2.965, 95%CI (1.284, 6.845), P=0.020], mechanical 20251606) ventilation time≥10 d [OR=3.577, 95%CI (1.185, 10.793), P=0.037] and hospital stay≥14 d before medication [OR=2.422, 95%CI (1.036, 5.654), P=0.041] were independent 15120420253@139.com risk factors, and anti-infective treatment course>7 d was a protective factor [OR=0.445, 95%CI (0.221, 0.895), P=0.043]. CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%. The mechanical ventilation time≥10 d, APACHE-Ⅱ score≥15 points 24 h before medication, and hospital stay≥14 d before medication may lead to treatment failure, whereas anti-infective treatment course>7 d may be associated with treatment success.

Under the trend of increasing aging, integrated elderly care and medical services is an important measure to optimize the supply of elderly care services and promote the good death of the elderly. Using the cooperative production theory and the classical grounded theory, a qualitative analysis was conducted on 38 cases of elderly palliative care and 25 cases of hospital-based palliative care under the integrated elderly care and medical services model from a hospital in Nanning City using Nvivo 20.0 software. This paper found that the integrated elderly care and medical services mode emphasized the deep integration of medical and elderly care services by integrating resources and improving service efficiency, to achieve the basic experience of comprehensive health care for the elderly. The promotion of these experiences has a positive significance for building a multi-agent cooperative production system, strengthening personnel training, perfecting the performance distribution mechanism, and further promoting the development of the national palliative care pilot.

Objective To investigate the prevalence of human soil-transmitted nematode infections in Congjiang County, Guizhou Province in 2023, so as to provide insights into soil-transmitted nematodiasis prevention and control in the county. Methods Congjiang County was divided into 5 areas according to geographical locations, and one township was randomly sampled from each area, followed by one administrative village randomly sampled from each township as the survey site. Two hundred permanent residents without deworming during the past three months were randomly sampled from each survey site using the random cluster sampling method. Participants’ fecal samples were collected, soil-transmitted nematode eggs were detected using the KatoKatz technique and the prevalence of human soil-transmitted nematode infections was compared among participants. Mild, moderate and severe soil-transmitted nematode infections were classified according to eggs per gram (EPG), and the proportions of mild, moderate and severe infections were estimated. In addition, participants’ family status and household sanitary toilets construction were investigated using questionnaires. Results A total of 1 001 participants were included at 5 survey sites in Congjiang County, and the overall prevalence of soil-transmitted nematode infections was 19.08% (191/1 001). The prevalence rates of Ascaris lumbricoides and hookworm infections were 2.30% (23/1 001) and 1.90% (19/1 001), with all egg-positives identified as mild infections, and the prevalence of Enterobius vermicularis infections was 0.10% (1/1 001). The prevalence of Trichuris trichiura infections was 15.78% (158/1 001) among participants, and there was a significant difference in the prevalence among survey villages (χ2 = 123.345, P < 0.001), with the highest prevalence detected in Liujia Village (39.00%), followed by in Longjiang Village (18.00%). There was an age-specific prevalence rate of T. trichiura infections among participants (χ2 = 166.050, P < 0.001), and the highest prevalence was detected among participants at ages of 10 to 19 years (48.19%), followed by at ages of over 70 years (14.53%) and 50 to 59 years (13.04%). There was an occupation-specific prevalence rate of T. trichiura infections among participants (χ2 = 74.134, P < 0.001), and the highest prevalence was detected among students (32.32%), followed by among workers/migrant workers (10.34%) and farmers (10.12%). There was an educational level-specific prevalence rate of T. trichiura infections among participants (χ2 = 28.761, P < 0.001), and the highest prevalence was detected among participants with an educational level of primary school (21.60%), followed by among illiterate participants (12.03%). There was an ethnicity-specific prevalence rate of T. trichiura infections among participants (χ2 = 42.193, P < 0.001). The proportions of mild, moderate and severe T. trichiura infections were 76.58% (121/158), 14.56% (23/158) and 3.16% (5/158), and all severe infections were identified among primary school students. T. trichiura infections were detected in 123 families, and there were 27 families (21.95%) in which two and more family members were identified with T. trichiura infections. A total of 1 001 valid questionnaires were recovered, and the prevalence rates of T. trichiura infections were 14.69% (139/964) and 34.55% (19/55) in families with and without sanitary toilets (χ2 = 15.410, P < 0.001). Conclusions The prevalence of soil-transmitted nematode infections was relatively high in Congjiang County, Guizhou Province in 2023, and the T. trichiura infections was notably serious. Intensified soil-transmitted nematodiasis control measures are recommended targeting primary school students, middle-aged and elderly farmers and migrant workers.

Objective:To investigate urinary pH distribution and its influencing factors in gout patients, to provide insights for individualized treatment.Methods:This is a retrospective study. The gout patients in the Gout Outpatient Department of the Affiliated Hospital of Qingdao University from September 2019 to August 2021 were collected. Clinical data were collected and relevant indicators were measured. The patients were divided into different groups according to urinary pH. Clinical characteristics and factors related to urinary pH were compared among the groups. SPSS 23.0 software was used.Results:A total of 2 553 patients were enrolled. There were significant statistical differences in age, body mass index, triglyceride, alanine aminotransferase(ALT), blood urea nitrogen, serum creatinine, estimated glomerular filtration rate(eGFR), blood uric acid, urinary uric acid/creatinine ratio, fraction excretion of uric acid(FEUA) among groups with different urinary pH( F were 5.114, 4.772, 7.170, 4.721, 13.603, 2.812, 3.422, 22.834, 18.230, 26.332, all P<0.05). Urinary uric acid and FEUA in acute group were higher than those in remission group( Z were -2.295, -3.528, both P<0.05). After adjusting for gender, age, eGFR, logistics regression analysis showed that body mass index, triglyceride, total cholesterol, ALT, blood uric acid, and blood urea nitrogen were still risk factors. Multivariate logistic regression analysis showed that triglyceride, blood uric acid, and blood urea nitrogen were independent risk factors associated with acid urine. Linear correlation analysis showed that urinary pH was negatively correlated with body mass index, triglyceride, total cholesterol, blood uric acid, fasting glucose, blood urea nitrogen, ALT( r were -0.079, -0.106, -0.051, -0.186, -0.040, -0.122, -0.051, all P<0.05), but positively correlated with eGFR( r=0.058, P=0.003). Conclusion:The overall urine pH levels in patients with primary gout are below normal reference. Several metabolic components are related to it. Triglyceride, blood uric acid, and blood urea nitrogen are independent risk factors of acidic urine. In clinical practice, attention should be paid to timely alkalization of urine to prevent complications.
