Clinical relevance of genetic polymorphisms in WNT signaling pathway (SFRP1, WNT3A, CTNNB1, WIF-1, DKK-1, LRP5, LRP6) on pulmonary tuberculosis in a Chinese population.

The present study was performed to evaluate the association of WNT signaling pathway genes variants with pulmonary tuberculosis (PTB) risk in Chinese Han population. Our study subjects were composed of 452 PTB patients and 465 normal controls, and seventeen SNPs of seven genes in WNT signaling pathway (SFRP1, WNT3A, CTNNB1, WIF-1, DKK-1, LRP5, LRP6) were genotyped by SNPscan technique. We found no significant relationship of SFRP1 rs10088390, rs4736958, rs3242, WNT3A rs752107, rs3121310, CTNNB1 rs2293303, rs1798802, rs4135385, WIF-1 rs1026024, rs3782499, DKK-1 rs2241529, rs1569198, LRP5 rs3736228, rs556442, LRP6 rs2302685, rs11054697, rs10743980 polymorphisms with PTB susceptibility. While, WIF-1 rs3782499 variant was associated with susceptibility to PTB under recessive model, and haplotype analysis showed that DKK-1 GA haplotype frequency was significantly increased in PTB patients. The WNT3A rs3121310, CTNNB1 rs2293303 polymorphisms were respectively associated with drug-induced liver injury (DILI), sputum smear-positive in PTB patients. The rs3782499 in WIF-1 gene was related to fever, leukopenia, and the rs1569198 in DKK-1 was linked to sputum smear-positive in PTB patients. In LRP5 gene, rs3736228, rs556442 variants respectively affected the occurrence of DILI, fever, and LRP6 gene rs2302685, rs10743980 variants respectively influenced the development of hypoproteinemia, sputum smear-positive in PTB patients. Our results revealed that WNT signaling pathway genes variation were not associated with the susceptibility to PTB, while WNT3A, CTNNB1, WIF-1, DKK-1, LRP5, LRP6 genetic variations might be closely related to the occurrence of several clinical characteristics of PTB patients.

Association of vision and hearing status with depressive symptoms among middle-aged and older Chinese adults.

Objective: Long-term untreated vision and hearing impairments can negatively impact physical and mental wellbeing. We investigated the association of vision and hearing status with depressive symptoms among middle-aged and older Chinese adults. Methods: This was a prospective cohort study of 9,492 participants from the China Health and Retirement Longitudinal Study (CHARLS) carried out in 2011, 2013, 2015, and 2018. This study used self-reported vision and hearing status to determine the degree of impairment. Depressive symptoms were examined using the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10), with a total score of ≥ 12 indicating depressive symptoms. A Cox proportional hazards model adjusted for age, sex, residence, marital status, educational level, smoking history, alcohol consumption, hypertension, diabetes, heart disease, digestive disease, arthritis, wearing glasses, and hearing aids was used to estimate the association of vision and hearing status with depressive symptoms among middle-aged and older Chinese adults. Results: Of the 9,492 participants [mean (SD) age at CHARLS baseline, 58.12 (9.00) years], 3,238 (34.11%) participants reported incident depressive symptoms during the 7-year follow-up period. Participants who self-reported only vision impairment [hazard ratios (HR): 1.14, 95% confidence intervals (CI): 1.05-1.24], only hearing impairment (HR: 1.24, 95% CI: 1.06-1.46), and both vision and hearing impairments (HR: 1.25, 95% CI: 1.08-1.45) were independently associated with a greater increase in the hazard risk of incident depressive symptoms compared to those without vision and hearing impairments. An increase in participants' vision and hearing scores was associated with a significant increase in the hazard risk of incident depressive symptoms (HR: 1.04, 95% CI: 1.03-1.06). Conclusion: Vision and hearing status was associated with increased depressive symptoms among middle-aged and older Chinese adults during the 7-year follow-up period. Participants' use of glasses and hearing aids did not improve their depressive symptoms. Our findings may facilitate the development of effective treatments to prevent and treat vision and hearing impairments, thereby enhancing the physical and mental wellbeing of middle-aged and older adults.

Job Burnout and Occupational Stressors among Chinese Healthcare Professionals at County-Level Health Alliances.

BACKGROUND: This study aimed to examine the degrees of job burnout and occupational stressors and their associations among healthcare professionals from county-level health alliances in Qinghai-Tibet Plateau, China. METHODS: A cross-sectional study was conducted in county-level health alliances in Qinghai Province, China, in November 2018. The Maslach Burnout Inventory-General Survey and the 38-item Chinese version of the "Scale for occupational stressors on clinicians" were used. Medical staff in four health alliances from two counties were invited to complete the questionnaire. RESULTS: A total of 1052 (age: 34.06 ± 9.22 years, 79.1% females) healthcare professionals were included, 68.2% (95% CI: 65.2-71.0%) of the participants had job burnout symptoms. Occupational stressors had positive associations with moderate (OR = 1.06, 95% CI: 1.05-1.07) and serious (OR = 1.15, 95% CI: 1.13-1.19) level of job burnout. Stressors from vocational interest produced the greatest magnitude of odds ratio (OR = 1.76, 95% CI: 1.62-1.92) for serious degree of burnout, followed by doctor-patient relationship, interpersonal relationship as well as other domains of occupational stressors. CONCLUSIONS: Job burnout was very common among healthcare professionals working in Chinese county-level health alliances, different occupational stressors had associations with job burnout. Appropriate and effective policies and measures should be developed and implemented.

Effects of health education on HIV/AIDS related knowledge among first year university students in China.

BACKGROUND: The number of new HIV infections has increased and implementation of school-based health education programs on AIDS have been advocated for a long time. OBJECTIVE: This study aimed to explore the effectiveness of an intervention of HIV/AIDS on the knowledge of HIV/AIDS prevention and control among first year university students. METHODS: An awareness questionnaire was adopted to assess awareness and knowledge of HIV/AIDS pre- and post-health education among first year university students in Qinghai, China. Independent sample t-test, chi-square test, and multiple logistic regression analyses were used. RESULTS: A total of 2,165 and 2,062 first year university students were respectively recruited pre- and post- HIV/AIDS health education. The awareness rate increased significantly after the health education intervention (from 48.59%, 95%CI: 46.47%-50.72% to 76.24%, 95%CI: 74.35%-78.06%). Students from Hui and Tibetan ethnicities, and those holding prejudices against AIDS patients were less knowledgeable than their counterparts regarding HIV/AIDS related knowledge, whereas urban-dwellers and those with higher paternal education were positively associated with awareness of HIV/AIDS related knowledge (p <0.05). CONCLUSION: HIV/AIDS awareness among first year university students improved greatly after receiving an education intervention, which underscores its utility as part of the approaches of HIV/AIDS control and prevention.
