Loneliness obviously prevails among empty nest older adults than non-empty nest older adults. Depressive symptoms showed a stronger risk of empty nest older adults being lonely. Family support was suggested as a protective factor for loneliness in both groups. These findings should be considered when developing intervention strategies to reduce loneliness.

We investigated the acceptability of early anti-retroviral therapy (ART) among HIV-infected people in Anhui Province, China. A cross-sectional study was conducted in 11 convenience selected cities of Anhui Province from September 2012 to December 2013. Study participants were convenience recruited from local Centers for Disease Control and Prevention when they attended for CD4(+) cell counts testing and HIV counselling. Answers to questionnaires were obtained through face-to-face structured interviews. Factors influencing the acceptability of early ART were identified by multiple logistic regression analysis. A total of 287 HIV-infected people met the criteria and completed the survey. The acceptability of early ART was 65.2%. The results of multiple logistic regression analysis indicated that the acceptability of early ART was associated with the following factors: CD4(+) T cell count (above 750 cells/µL vs. 350 cells/µL to 550 cells/µL: OR = 0.144, P < 0.001), years of HIV diagnosis confirmation (1 year to 5 years vs. <1 year: OR = 0.418, P = 0.005; above 5 years vs. <1 year: OR = 0.160, P < 0.001), whether had sexual behaviour after HIV diagnosis confirmation (yes vs. no: OR = 2.342, P = 0.005) and the awareness of two early ART-related questions (OR = 4.101, P = 0.015; OR = 3.294, P < 0.001). In summary, the present study showed that most HIV-infected people can accept early ART. Early ART interest in Anhui HIV-infected population was high. The awareness of early ART-related knowledge in HIV-infected population was low and should be improved to achieve higher acceptability and keep adherence to early ART for HIV prevention.

The aim of this study was to investigate the effects of Grape Seed Proanthocyanidins (GSP) on Nω-Nitro-L-arginine methyl ester-induced hypertension in pregnant mice. Fifty Kunming mice were randomized into control, control + GSP, model, and model + GSP. Three weeks later, the artery systolic blood pressure was examined and the related pathological changes were detected. Aorta relaxation function was assessed by aorta ring apparatus. Blood urea nitrogen and serum creatinine were measured by an automatic biochemistry analyzer. Colorimetric analysis, enzyme-linked immunosorbent assay, immunofluorescence, and western blot were applied to detect related indicator in serum, cardiac, and kidney tissues. The results showed that GSP treatment for 3 weeks could improve cardiovascular and kidney remodeling indexes and decrease blood urea nitrogen and serum creatinine content in serum, as well as could ameliorate oxidative stress status and endothelial dysfunction. Therefore, it is for the first time found that GSP exerts protective effect against Nω-Nitro-L-arginine methyl ester-induced hypertension in pregnant mice, which provided a theoretical basis for potential application in the clinic.
