Rapid HIV voluntary counselling and testing (RVCT) is an alternative method of standard HIV voluntary counselling and testing (SVCT). Less is known about whether RVCT improves the receipt rate of HIV test results among clients who seek HIV counselling and testing. We aimed to evaluate effectiveness of RVCT on result receipt rate. We conducted a comprehensive search of databases containing Medline, EBSCO, Web of science, and Cochrane library to identify studies published up to August 2012. Reviewers extracted information independently. Risk of bias was evaluated with Cochrane Collaboration’s tool for assessing study quality. Five randomised controlled trials were included and analysed for the result receipt rate using a random-effects model. The pooled receipt rate of HIV test results in the RVCT was significantly higher than in the SVCT (RR = 1.74, 95% CI = 1.47–2.07). Our results suggest RVCT as a favourable method to increase the receipt of HIV test results. Only two included studies assessed the modification of risk behaviour after HIV-CT in a different manner; also, the sample size was small in the current meta-analysis. In future research, it is necessary to confirm the effect of RVCT on disinhibition of post-test risk behaviour. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav Source

Recently, there has been a significant increase in the rate of multiple births in most developed countries. However, few population-based studies have been conducted in China regarding the epidemiology of twin births in recent years. We performed a descriptive analysis of twin births from 1993 to 2005 using data from a population-based perinatal care program in southeast China. The twin birth rate in southeast China was 0.65%, and the twin birth rates from 1993 to 2005 fluctuated between 0.60% and 0.70%. During the three periods of 1993-1996, 1997-2000, and 2001-2005, the twin birth rate increased from 0.57% to 0.71% in urban areas (p =.005) and from 0.59% to 0.68% in mothers who had an education level of high school or higher (p =.046). After 2000, the twin birth rate of primiparae 30 years of age and older significantly increased from 0.72% to greater than 1.20%. We concluded that the twin birth rates in southeast China from 1993 to 2005 stayed constant in the overall population but increased in certain subgroups of women, presumably due to increased use of fertility treatment and the development of assisted reproductive technology. © The Authors 2013.

The aim of the study was to determine whether the area of Tanggu, Tianjin Binhai New Economic Developing Area, China, is subject to similar effects of ambient particulate matter less than 10 micrometres in aerodynamic diameter (PM10) similar to other areas of China. This study was designed to investigate cause-specific mortality risks associated with air pollution in this geographical region. The present study used a time-series analysis to explore the relationship between PM10 and the cause-specific mortalities for non-accidental, cardiovascular, and cardiopulmonary mortality from 1 January 2006 to 31 December 2010. A 10 μg/m3 increment of PM10 was associated with a 1.02% (95% confidence interval (CI): 0.48, 1.56) increase in cardiovascular mortality, and a 0.88% (95% CI: 0.36, 1.39) increase in cardiopulmonary mortality. In addition, the effects from PM10 appear to be consistent with multi-pollutant models. The results show that there are strong associations between daily cardiovascular and cardiopulmonary mortality and ambient PM10 exposure. © 2013 Taylor & Francis. Source
