What's community got to do with it? Implementation models of syringe exchange programs.

Syringe exchange programs (SEPs) have been shown to be highly effective in reducing HIV transmission among injection drug users (IDUs). Despite this evidence, SEPs have not been implemented in many communities experiencing HIV epidemics among IDUs. We interviewed 17 key informants in nine U.S. cities to identify factors and conditions that facilitated or deterred the adoption of SEPs. Cities were selected to represent diversity in size, geographic location, AIDS incidence rates, and SEP implementation. Key informants included HIV prevention providers, political leaders, community activists, substance use and AIDS researchers, and health department directors. SEPs were established by one or more of three types of implementation models: (a) broad community coalition support, (b) community activist initiative, and (c) top-down decision making by government authorities. In each model, coalition building and community consultation were critical steps for the acceptance and sustainability of SEPs. When others were not prepared to act, community activists spearheaded SEP development, taking risks in the face of opposition, but often lacked the resources to sustain their efforts. Leadership from politicians and public health officials provided needed authority, clout, and access to resources. Researchers and scientific findings lent force and legitimacy to the effort. Rather than adopting adversarial positions, successful SEP implementers worked with or avoided the opposition. Fear of repercussions and lack of leadership were the greatest barriers to implementing SEPs. Communities that successfully implemented SEPs were those with activists willing to push the agenda, public officials willing to exercise leadership, researchers able to present authoritative findings, and proponents who effectively mobilized resources and worked to build community coalitions, using persistent but nonadversarial advocacy.

HIV risk behavior among amphetamine injectors at U.S. syringe exchange programs.

The goal of this study was to compare HIV risk behaviors of amphetamine and non-amphetamine injectors at syringe exchange programs (SEP) in the United States and to identify factors associated with injection risk. This analysis is based on data from a random cross-section of participants at 13 SEPs in different parts of the country. All interviews were done using Audio Computer-Assisted Personal Interviewing technology. Amphetamine injectors differ from other SEP participants in that they are younger and more likely to be White, to have had a recent same sex partner, and to be homeless. Rates of injection risk behavior are higher among amphetamine injectors than other SEP participants, but rates of condom use are similar. Factors associated with injection risk behavior are amphetamine injection, homelessness, depression, and having a recent same-gender sexual partner (for both men and women). SEPs have been repeatedly demonstrated to reduce injection risk behavior, but some groups of program participants continue to be at elevated risk. SEPs may need to develop new approaches to outreach and education to address the needs of amphetamine injectors and other populations at persistent risk.

Syringe exchange programs in Brazil: preliminary assessment of 45 programs.

The present study aims to evaluate the current operation of Brazilian syringe exchange programs (SEP). After consulting national and regional networks of people working in projects/programs aiming to reduce drug-related harm, we identified 134 potential participant programs. Unfortunately, only 45 SEPs answered a survey, even after repeated attempts. The survey addressed: coverage, funding, procurement of basic supplies, managerial capacity, and the local political environment. Findings were triangulated with in-depth interviews with key informants. The main findings included: satisfactory adherence to the initiatives and adequate documentation, but deficiencies in terms of coverage and monitoring, and uneven procurement of resources. Program personnel work mostly on a provisional basis, despite the efforts of local coordinators. Most programs are funded by the National STDs/AIDS Program. A comprehensive agenda aiming to improve current operations should include: concerted efforts to improve local and regional databanks, incentives/sanctions toward full accountability of initiatives carried by the programs, and a genuine culture of monitoring and evaluation.

A capture-recapture technique to estimate the size of the injecting drug user population attending syringe exchange programs: AjUDE-Brasil II Project.

This paper presents the results of a study with a two-occasion capture-recapture design. The data are part of the AjUDE-Brasil II Project, carried out in 2000-2001. Estimation of the size of the IDU population attending a syringe-exchange program (SEP) in São José do Rio Preto, Salvador, and Porto Alegre, Brazil, was performed using Chao's model. Capture probabilities were also estimated. For Porto Alegre a comparison of the results from the AjUDE-Brasil I and AjUDE-Brasil II Projects was performed. Results are also presented for error rates secondary to the choice of matching criteria.

Effects of an intensive street-level police intervention on syringe exchange program use in Philadelphia, PA.

Repeated measurements and mixed-effects models were used to analyze the effects of an intensive long-term street-level police intervention on syringe exchange program use. Utilization data for 9 months before and after the beginning of the intervention were analyzed. Use fell across all categories and time periods studied, with significant declines in use among total participants, male participants, and Black participants. Declines in use among Black and male participants were much more pronounced than decreases among White and female participants.

Reduced risk of hepatitis B and hepatitis C among injection drug users in the Tacoma syringe exchange program.

OBJECTIVES: This case-control study examined the association between syringe exchange use and hepatitis B and C in injection drug users. METHODS: Case patients included 28 injection drug users with acute hepatitis B and 20 with acute hepatitis C reported to the health department in a sentinel hepatitis surveillance county; control subjects were injection drug users with no markers of exposure to hepatitis B or C (n = 38 and 26, respectively) attending health department services during the same period. Data were abstracted from clinic records. RESULTS: Seventy-five percent of case patients with hepatitis B and 26% of control subjects had never used the exchange; similar proportions were found for the hepatitis C case and control groups. After adjustment for demographic characteristics and duration of injecting drugs, nonuse of the exchange was associated with a sixfold greater risk of hepatitis B (odds ratio [OR] = 5.5; 95% confidence interval [CI] = 1.5, 20.4) and a sevenfold greater risk of hepatitis C (OR = 7.3; 95% CI = 1.6, 32.8). CONCLUSIONS: The results suggest that use of the exchange led to a significant reduction in hepatitis B and hepatitis C in the county and may have also prevented a substantial proportion of human immunodeficiency virus infections in injection drug users.

Drug addicts and syringe sharing in France: epidemiological study 1988.

A cross-sectional study was carried out in France in March 1988 to measure the impact made on drug abusers by educational campaigns concerning HIV transmission and the lifting of restrictions on the sale of syringes. Thirty-two drug-dependence centers provided a sample of 479 subjects who, compared with 4,846 subjects enrolled in 1986, were found to differ particularly in the type of substance used. Since no observations were made before the introduction of the preventive measures, the changes cannot be attributed to these alone. However, mean profiles were obtained by comparing the different groups, the results obtained remaining dependent on the method of recruitment (specialized centers) and the retrospective nature of the data.

Syringe pumps and start-up time: ensuring safe practice.

The start-up time is the delay between starting an infusion pump and the delivery of fluid at the set flow rate. Mechanical slack in syringe pumps can lead to start-up delays of an hour or more at low-flow rates. During this period no medication is delivered to the patient. The causes of the start-up time delay, its implications and methods of minimising the delay are explained.

Prevalence and risk factors for positive tuberculin skin tests among active drug users at a syringe exchange program.

OBJECTIVES: To evaluate the prevalence and predictors of tuberculin skin test (TST) reactions > or =10 mm among active injection drug users (IDUs) at a syringe exchange program in New York City. METHODS: From August 1995 to January 1996, participants were offered TB screening, an interview, and received $15.00 upon returning for skin test interpretation. RESULTS: 610/650 (94%) consented to screening. Of the 566 (93%) who returned for skin test readings, skin test data were available for 564 (99.8%); 14% (95% CI 11.6-17.4) had TSTs > or =10 mm. When the > or =5 mm threshold for interpretation of TST among HIV-infected persons was used, the prevalence of TST positivity increased by only 1%. In univariate analysis, the prevalence of TST > or =10 mm increased with age and with increasing years of IDU (both P = 0.001). Because of a strong correlation between age and duration of IDU, two logistic regression models were examined. In the model with age alone, a history of self-reported TST positivity (OR 8.88; 95% CI 4.9-16.09; P = 0.0001) and increasing age (OR per 10 years increase in age, 1.69; 95% CI 1.24-2.29; P = 0.0008) were independent predictors of TSTs > or =10 mm. In the model with duration of IDU, a history of TST positivity (OR 8.82; 95% CI 4.74-16.41; P = 0.0001) and duration of IDU (OR per 10 years of IDU, 1.46; 95% CI 1.10-1.94; P = 0.0081) were independent predictors of TST > or =10 mm. CONCLUSIONS: Use of the reduced cutoff point for TST positivity from 10 mm to 5 mm did not significantly affect the prevalence of positive TSTs in this cohort of active drug users. Increased prevalence of TB infection with age suggests a high annual incidence of TB infection in this population, and the increased risk of TB infection with increasing duration of IDU suggests that the duration spent in IDU environments may increase infection risk.

[The effect of a syringe-exchange program on a decrease in the risk of HIV infection among intravenous narcotic abusers in the city of Rostov-on-Don].

The necessity and effectiveness of introducing the program of the exchange of syringes for intravenous drug users as a preventive and antiepidemic measure are discussed. Preventive and antiepidemic measures within the concept of harm reduction are described. The comparative analysis of materials obtained as a result of two sociological questionings, carried out in 1997-1998 among the representatives of the community (random nonrepeating choice) and in the middle of 1999 among the participants of the program revealed that the participants of the program had statistically significant changes in risky behavior patterns during the use of injection drugs.

Utilization of the aquatic research facility and fertilization syringe unit to study sea urchin development in space.

Methods were developed for the investigation of the effects of microgravity on early development in sea urchins within the Canadian Space Agency's Aquatic Research Facility (ARF). The ARF payload provided light, temperature control, automated fixation capability, and a 1 G on-orbit centrifuge control. Eggs and embryos of either the sea urchin species Lytechinus pictus or Strongylocentrotus purpuratus were loaded into Standard Container Assemblies (SCAs) which comprised the experimental aquaria (33 mL volume) contained within the ARF. A newly developed Fertilization Syringe Unit (FSU) was used to achieve "in-flight" fertilization capability. Fixative solutions were preloaded into fixation blocks maintained adjacent to the SCAs and injected at pre-selected time points, resulting in final (diluted) concentrations of either 0.5% or 2% glutaraldehyde (depending upon embryonic stage). Light, scanning, and transmission electron microscopy determined that all desired embryonic and cell division stages (16-cell stage, blastula, gastrula, and pluteus) were preserved using the experimental protocols and fixation capability provided by the ARF/FSU system.

Syringe-cartridge solid-phase extraction method for patulin in apple juice.

A syringe-cartridge solid-phase extraction (SPE) method was developed for determination of patulin in apple juice. A 2.5 mL portion of test sample was passed through a conditioned macroporous SPE cartridge and washed with 2 mL 1% sodium bicarbonate followed by 2 mL 1% acetic acid. Patulin was eluted with 1 mL 10% ethyl acetate in ethyl ether and determined by reversed-phase liquid chromatography using a mobile phase consisting of 81% acetonitrile, 9% water, and 10% 0.05M potassium phosphate buffer, pH 2.4. Recoveries averaged 92% and the relative standard deviation was 8.0% in test samples spiked with 50 ng/mL patulin. The method appears to be applicable for monitoring apple juice samples to meet the U.S. Food and Drug Administration compliance action level of 50 microg/kg in an industrial quality assurance laboratory environment.

[Study on the pharmacokinetics and bioavailability of syringic acid in rabbits].

OBJECTIVE: To study the pharmacokinetics and bioavailability of syringic acid(SA) in rabbits by HPLC. METHOD: After the rabbits were injected SA injection via ear vein and peritoneal cavity, blood was collected also via ear vein at different time-point. Then the concentration of SA in blood was determined by HPLC and the concentration-time curve was mapped to simulate a compartment model. So the pharmacokinetic parameters were calculated out. Several days after this injection, the drug was administered to the rabbits via i.p. and using the same method, another concentration-time curve was obtained. By comparing the AUC of the two curves, bioavailability was obtained. RESULTS: The concentration-time curve of SA in rabbits after i.v. fitted in a two-compartment open model and the absolute bioavailability was 86.27%. CONCLUSION: The results were valuable for the clinical application of new anti-endotoxic drug from Radix Isatidis.

[Children's distress during application of local anaesthesia. Computerized tool versus traditional syringe].

This study compared the level of distress in children during the application of local anaesthesia by a computerized tool (Wand) and by a traditional syringe. The influence of children's mild or extreme anxiety regarding the dental procedure was also determined. 125 children between the ages of 4 and 11 years old participated in this study. Their discomfort was recorded on videotape and marked on the Venham scale and the Observational Scale of Behavioral Distress at 15 second intervals. Parents rated their child's level of anxiety on the Dental Subscale of the Children's Fear Survey Schedule. The results indicate that mildly anxious children suffered less distress and showed less muscle tension, verbal protest and body movement during the first 2 intervals when the computerized tool was used. However, the maximum distress score at the moment of injection was similar in both methods. There was no difference found in the level of distress in the highly anxious children.

[Hidradenoma of the skin. Synoptic reveiw of syringeal hidradenoma, eccrine epithelioma and eccrine basalioma (author's transl)].

An ulcerating and sclerosing skin tumour on the temporal forehead region is described. Histologically the tumour is composed of different structures as cystic hidradenoma, syringoma, ductal hidradenoma and sclerres as cystic hidradenoma, syringoma, ductal hidradenoma and sclerosing basalioma arranged in layers. The tumour appears to be a distinct and diagnosable entity. It exists a major similarity to such tumours reported as syringeal hidradenoma, eccrine epithelioma or eccrine basalioma.

Metabolism of ferulic and syringic acids by micromycetes.

The ability of 814 strains of Micromycetes to grow on ferulic and syringic acids was investigated. After cultivation on solid media, 106 and 108 strains were selected and cultivated in liquid synthetic medium. Chromatographic analysis allowed classification of fungi into different groups according to the consumption of phenolic compounds and the appearance of new metabolites. Finally, Paecilomyces variotii and Pestalotia palmarum were chosen and cultivated in the presence of ferulic acid in two different culture media. These two Fungi Imperfecti were able to consume the phenolic compound rapidly and completely.

[Treatment of unstable diabetes mellitus in children and adolescents using insulin administered by a semi-automated syringe, NovoPen].

An insulin device, NovoPen, incorporating human actrapid insulins was used in a group of 6 poor--controlled diabetic adolescents, aged 15 years (mean 8-18.7) with duration of diabetes 8.2 +/- 4.8 years (mean +/- S.D). The study was carried out in insulin-dependent diabetic young-people, to test the efficacy and acceptance of an intensified insulin therapy (an injection of short-acting insulin before each of the three meals using NovoPen plus an evening injection of human ultratard insulin from a conventional syringe) in the hope of achieving the improved control. All patients completed a 6-months NovoPen-therapy and preferred to continue with the multiple injection regimen in the long term. Metabolic control was improved, the values of haemoglobin A1c decreased from 16.8% to 13.4% (statistically significant) during the study. The use of the NovoPen injection device proved to be a safe and acceptable method of therapy; it offered the patients a marked freedom and liberalization of everyday life.
