The objective of this study was to reveal the relationships of mental health, social support, health-related quality of life (HRQOL) as well as their dimensions in HIV-positive men who have sex with men (MSM).HIV-positive MSM were interviewed by a cross-sectional study design using the world Health Organization quality of life bref scale, social support rating scale, and self-rated anxiety and depression scales. Canonical correlation analysis and structural equation model (SEM) were utilized to analyze to the collected data.Three first pair of canonical variables that was statistically significant (P < .0001) and verified could account for the largest cumulative proportion were computed from canonical correlation analysis. The results showed, among the dimensions, depression and anxiety were negatively correlated with support utilization and physical health, while subjective support and support utilization were positively correlation with social relationship health. Structural equation model results showed that support utilization (0.632, T = 10.44), depression (0.816, T = 20.37), and environmental dimension (0.833, T = 38.47) had the largest standardized factor loading in social support, mental health, and HRQOL. The structural coefficient between social support and mental health was −0.433 (T = −5.88), between mental health and HRQOL was −0.592 (T = −10.33), between social support and HRQOL was 0.290 (T = 4.10), indicated social support not only exerted a direct influence, but also mediated mental health to have an indirect effect on HRQOL for HIV-positive MSM.Environmental dimension is the foremost factor of HRQOL for HIV-positive MSM. Alleviating anxiety symptoms maybe improve physical health, while promoting the support utilization is an effective measure of alleviating depression and improving social relationship health for this special group.

Background: The novel coronavirus disease 2019 (COVID-19) outbreak started in Wuhan, Hubei, China since Dec 2019 and cases of infection have been continuously reported in various countries. It is now clear that the SARS-COV-2 coronavirus is transmissible from human to human. Nucleic acid detection is considered as the gold standard for the diagnosis of COVID-19. In this case report, we describe our experience in detection of SARS-COV-2 from a confirmed patient using nucleic acid test of bronchoalveolar-lavage fluid (BALF) samples but not nasopharyngeal swabs. Case presentation: We present a case of severely ill SARS-COV-2 infected 46-year-old man with fever, coughing and chest tightness. We performed viral detection using his BALF samples and imaging method (CT) for confirmation. The patient received combination of interferonalfa-1b and ribavirin, lopinavir and ritonavir for antiviral treatment at different stages. Other medication was also given to him in combination for anti-inflammation, intestinal microbial regulation, phlegm elimination, liver protection and pulmonary fibrosis prevention purposes. We provided oxygen supply to him using BIPAP ventilator and high-flow humidification oxygen therapy instrument to facilitate respiration. The patient was cured and discharged. Conclusion: This case report described an effective supportive medication scheme to treat SARS-COV-2 infected patient and emphasized the necessity of detection of the viral genome using BALF samples and its significance in the diagnosis and prognosis of the disease.

Among 417 COVID-19 patients in Shenzhen, demographic characteristics, clinical manifestations and baseline laboratory tests showed significant differences between mild-moderate cohort and severe-critical cohort.Based on these differences, a convenient mathematical model was established to predict the illness severity of COVID-19. The model includes four parameters: age, BMI, CD4 + lymphocytes and IL-6 levels. The AUC of the model is 0.911.The high risk factors for developing to severe COVID-19 are: age R 55 years, BMI > 27 kg / m 2 , IL-6 R 20 pg / ml, CD4 + T cell % 400 count / m L.Among 249 discharged COVID-19 patients, those who recovered after 20 days had a lower count of platelet, a higher level of estimated glomerular filtration rate, and higher level of interleukin-6 and myoglobin than those who recovered within 20 days.

In this study, blood samples from newly HIV-1 infected men who have sex with men (MSM) were collected, and HIV-1 genotypes were identified based on gag p17-p24 and nef gene regions. We found that participants aged from 20 to 40 years old were the major infection group in Harbin. CRF01_AE was the predominant genotype, contributing to 84.7% of HIV-1 infections, followed by subtype B (4.7%), CRF07_BC (3.5%), and subtype B' (Thai B, 1.2%). Moreover, five unique recombinant forms (5.9%) were also identified, including genotypes 01B, 01C, and 01/02. The recombinant CRF01_AE/CRF02_AG was first reported in China. These results suggested that current HIV-1 genotype epidemic among MSM in Harbin is more complicated and that intersubtype recombinants have emerged. Therefore, timely regional epidemiological surveillance of HIV-1 genotype and development of prevention measures for new HIV-1 infections among MSM are quite important.
