Abstract
The aim of this study was to develop and externally validate a simple-to-use nomogram for predicting the survival of hospitalised human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients (hospitalised person living with HIV/AIDS (PLWHAs)). Hospitalised PLWHAs (n = 3724) between January 2012 and December 2014 were enrolled in the training cohort. HIV-infected inpatients (n = 1987) admitted in 2015 were included as the external-validation cohort. The least absolute shrinkage and selection operator method was used to perform data dimension reduction and select the optimal predictors. The nomogram incorporated 11 independent predictors, including occupation, antiretroviral therapy, pneumonia, tuberculosis, Talaromyces marneffei, hypertension, septicemia, anaemia, respiratory failure, hypoproteinemia and electrolyte disturbances. The Likelihood χ2 statistic of the model was 516.30 (P = 0.000). Integrated Brier Score was 0.076 and Brier scores of the nomogram at the 10-day and 20-day time points were 0.046 and 0.071, respectively. The area under the curves for receiver operating characteristic were 0.819 and 0.828, and precision-recall curves were 0.242 and 0.378 at two time points. Calibration plots and decision curve analysis in the two sets showed good performance and a high net benefit of nomogram. In conclusion, the nomogram developed in the current study has relatively high calibration and is clinically useful. It provides a convenient and useful tool for timely clinical decision-making and the risk management of hospitalised PLWHAs.

Abstract
China's HIV/AIDS epidemic continues to grow in rural and less developed areas. This consecutive cross-sectional study examines demographic and behavioral factors associated with HIV/STI infection, Hepatitis C (HCV) and other sexually transmitted infections (STIs) among Vietnamese female sex workers (FSW), a vulnerable population who cross into Guangxi, China. This study is a secondary data analysis of 303 Vietnamese and 4,348 Chinese FSWs recruited over seven years from two Chinese counties that border Vietnam. Logistic regression models compared demographics, HIV/STI status, HIV/AIDS-related knowledge, attitudes, and risk behaviors between Vietnamese FSWs and Chinese FSWs. Compared with Chinese FSWs, Vietnamese FSWs were younger, had attained lower education levels, were highly mobile, more likely to report using drugs, and were more vulnerable to HIV/STIs. Younger age, less educational attainment, shorter time in their current working location, no voluntary HIV testing in the last year, greater drug use, and not using condoms for all commercial sex in the last month were associated with higher HIV/STIs. In conclusion, several factors were associated with HIV/STI risk in Vietnamese cross-border FSWs. There is a pressing need to improve support systems for Vietnamese cross-border FSW and health system cooperation across the Chinese/Vietnamese border.
