Health-related quality of life of Chinese AIDS patients: a multi-region study.

OBJECTIVE: To assess the health-related quality of life (HRQOL) of Chinese AIDS patients in three regions (Shanghai, Zhejiang, and Henan) and to examine the relationship between region and the HRQOL. METHOD: A cross-sectional study was conducted from 2017 to 2018. Multistage stratified sampling was employed to recruit 1,273 AIDS patients from local Centers for Disease Control and Prevention. Data were collected by means of face-to-face interview using a structured questionnaire including the SF-12 and various rating scales. The multivariate linear and logistic regression models were performed to analyze the relationship of region and a variety of factors with the HRQOL and health utility. RESULTS: The three most affected dimensions were mental health, general health, and vitality as 18.2%, 18.0%, and 16.4% of the patients reported problems respectively. The mean (SD) scores of physical component summary (PCS) and mental component summary (MCS), were 48.19 (8.02) and 46.74 (10.71) respectively. The mean (SD) health utility score was 0.75 (0.13) assessed by the SF-6D derived from the SF-12. Region, age, employment status, individual income, government assistance and stigma significantly affected the patients' HRQOL (P < 0.01). BMI, opportunistic infection, treatment compliance and time of treatment were also found to be significant factors of the HRQOL. CONCLUSION: This study comprehensively estimated the HRQOL and health utility for the AIDS population in China, their HRQOL was mainly deteriorated in psychological dimensions, and geographical area may be closely related. Hence, close attention needs to be paid on the regional differences in HRQOL and the psychological problems of the patients.

An unprecedented fully reduced {MoV 60} polyoxometalate: from an all-inorganic molecular light-absorber model to improved photoelectronic performance.

Fully reduced polyoxometalates are predicted to give rise to a broad and strong absorption spectrum, suitable energy levels, and unparalleled electronic and optical properties. However, they are not available to date. Here, an unprecedented fully reduced polyoxomolybdate cluster, namely Na8[MoV 60O140(OH)28]·19H2O {MoV 60}, was successfully designed and obtained under hydrothermal conditions, which is rare and is the largest fully reduced polyoxometalate reported so far. The MoV 60 molecule describes one Keggin {ε-Mo12} encapsulated in an unprecedented {Mo24} cage, giving rise to a double truncated tetrahedron quasi-nesting architecture, which is further face-capped by another four {Mo6} tripods. Its crystalline stability in air, solvent tolerance, and photosensitivity were all shown. As a cheap and robust molecular light-absorber model possessing wide light absorption, MoV 60 was applied to build a co-sensitized solar cell photoelectronic device along with N719 dyes and the optimal power conversion efficiency was 28% higher than that of single-dye sensitization. These results show that MoV 60 polyoxometalate could serve as an ideal model for the design and synthesis of all-inorganic molecular light-absorbers for other light-driven processes in the future.
