Direct and indirect acquisition of syringes from syringe exchange programmes in Baltimore, Maryland, USA

Syringe exchange programmes (SEPs) are a fundamental source of sterile syringes and other health services for injection drug users (IDUs). However, various obstacles prevent many individuals from obtaining syringes from this source. As a result, some IDUs acquire syringes from “secondary exchangers”. The current study assessed the acquisition of syringes from the Baltimore City Needle Exchange Program (BNEP) as well as factors associated with obtaining syringes from the BNEP. Participants were asked to identify the colour of the cap of the most recently obtained syringe (red or grey cap suggested BNEP origins). In addition, support and risk network variables were examined. Although 38% reported using a syringe with a grey or red cap, only 7% reported that the BNEP was their primary source of syringes. Multivariate analyses showed that reporting the most recent syringe cap as red or grey was associated with obtaining syringes from the BNEP, obtaining syringes from a spouse, obtaining syringes from friends/neighbours, and number of drug users in their network. Based on these findings, encouraging secondary exchange is an effective method of providing injectors with syringes.     

参附注射液在胃癌术前介入化疗中的作用

研究参附注射液在胃癌术前介入化疗中的作用，将87例进展期胃癌患者分成两组。分别检测T细胞亚群、白细胞总数及淋巴细胞数量等。结果：参附组对CD3、CD4，CD4／CD8的提高作用显著高于化疗组，且能保持白细胞及淋巴细胞的数量。提示参附注射液可增强胃癌术前介入化疗的患者的细胞免疫功能。

Estimating numbers of injecting drug users in metropolitan areas for structural analyses of community vulnerability and for assessing relative degrees of service provision for injecting drug users

This article estimates the population prevalence of current injection drug users (IDUs) in 96 large US metropolitan areas to facilitate structural analyses of its predictors and sequelae and assesses the extent to which drug abuse treatment and human immunodeficiency virus (HIV) counseling and testing are made available to drug injectors in each metropolitan area. We estimated the total number of current IDUs in the United States and then allocated the large metropolitan area total among large metropolitan areas using four different multiplier methods. Mean values were used as best estimates, and their validity and limitations were assessed. Prevalence of drug injectors per 10,000 population varied from 19 to 173 (median 60; interquartile range 42–87). Proportions of drug injectors in treatment varied from 1.0% to 39.3% (median 8.6%); and the ratio of HIV counseling and testing events to the estimated number of IDUs varied from 0.013 to 0.285 (median 0.082). Despite limitations in the accuracy of these estimates, they can be used for structural analyses of the correlates and predictors of the population density of drug injectors in metropolitan areas and for assessing the extent of service delivery to drug injectors. Although service provision levels varied considerably, few if any metropolitan areas seemed to be providing adequate levels of services.
