The ethics of community-based research with people who use drugs: results of a scoping review.

Background: Drug user networks and community-based organizations advocate for greater, meaningful involvement of people with lived experience of drug use in research, programs and services, and policy initiatives. Community-based approaches to research provide an opportunity to engage people who use drugs in all stages of the research process. Conducting community-based participatory research (CBPR) with people who use drugs has its own ethical challenges that are not necessarily acknowledged or supported by institutional ethics review boards.

Modest rise in chlamydia and gonorrhoea testing did not increase case detection in a clinical HIV cohort in Ontario, Canada.

Objectives: We described patterns of testing for chlamydia and gonorrhoea infection among persons in specialty HIV care in Ontario, Canada, from 2008 to 2011.

Methods: We analysed data from 3165 participants in the OHTN Cohort Study attending one of seven specialty HIV care clinics. We obtained chlamydia and gonorrhoea test results via record linkage with the provincial public health laboratory.

Background: Injection drug use is a skill learned in social settings. Change the Cycle (CTC), a peer-delivered, one-session intervention, is designed to reduce among people who inject drugs (PIDs) injection initiation-related behaviours (i.e.

What is low threshold methadone maintenance treatment?

Background: Low threshold methadone maintenance (MMT) was developed for clients who do not have abstinence as a treatment goal. We explored how MMT programs in Canada defined low threshold and the challenges they faced.

Methods: Using semi-structured interviews, we collected data from clients (n=46), nurses/counsellors (n=15) and physicians (n=9) at three low threshold MMT programs.

Frequent food insecurity among injection drug users: correlates and concerns.

Background: Food insecurity and nutrition are two topics that are under-researched among injection drug users (IDUs). Our study examined the extent and correlates of food insecurity among a sample of IDUs and explored whether there is an association between food insecurity and injection-related HIV risk.

Methods: A cross-sectional survey was conducted using interviewer-administered questionnaires.

Acute and chronic respiratory symptoms among primary care patients who smoke crack cocaine.

Among inner-city populations in Canada, the use of crack cocaine by inhalation is prevalent. Crack smoking is associated with acute respiratory symptoms and complications, but less is known about chronic respiratory problems related to crack smoking. There is also a gap in the literature addressing the management of respiratory disease in primary health care among people who smoke crack.

Prevalence and correlates of GB virus C infection in HIV-infected and HIV-uninfected pregnant women in Bangkok, Thailand.

GB virus C (GBV-C) is an apathogenic virus that has been shown to inhibit HIV replication. This study examined the prevalence and correlates of GBV-C infection and clearance in three cohorts of pregnant women in Thailand. The study population consisted of 1,719 (1,387 HIV-infected and 332 HIV-uninfected) women from three Bangkok perinatal HIV transmission studies.

Giving away used injection equipment: missed prevention message?

Background: Our objective was to examine factors associated with distributive injection equipment sharing and how needle exchange programs (NEPs) can help reduce distributive sharing among injection drug users (IDUs).

Methods: 145 English speaking Canadian IDUs ages 16 years and over who had injected in the past 30 days were recruited for a cross-sectional survey. Participants were asked about their socio-demographic characteristics, HIV risk behaviours, social support, drug treatment readiness, program satisfaction, health and social service use and NEP drug use.

An indigenous plant food used by lactating mothers in west Africa: the nutrient composition of the leaves of Kigelia africana in Ghana.

Although the leaves of Kigelia africana are used to make a palm-nut soup which is consumed mainly by lactating women in many parts of sub-Saharan Africa, little is known about the nutrient qualities of this underutilized and underappreciated plant food. Leaves of Kigelia africana, called "sausage tree" in English and "nufuten" in the Twi language of Ghana, were collected in Kumasi and analyzed for their content of nutritionally important fatty acids, amino acids, minerals, and trace elements. The dried leaves contained 1.

Extraction of beryllium from refractory beryllium oxide with dilute ammonium bifluoride and determination by fluorescence: a multiparameter performance evaluation.

Beryllium exposure can cause a number of deleterious health effects, including beryllium sensitization and the potentially fatal chronic beryllium disease. Efficient methods for monitoring beryllium contamination in workplaces are valuable to help prevent dangerous exposures to this element. In this work, performance data on the extraction of beryllium from various size fractions of high-fired beryllium oxide (BeO) particles (from < 32 microm up to 212 microm) using dilute aqueous ammonium bifluoride (ABF) solution were obtained under various conditions.

Mother-to-child transmission of GB virus C in a cohort of women coinfected with GB virus C and HIV in Bangkok, Thailand.

Background: GB virus C (GBV-C) is an apathogenic virus that inhibits human immunodeficiency virus (HIV) replication in vitro. Mother-to-child transmission (MTCT) of GBV-C has been observed in multiple small studies. Our study examined the rate and correlates of MTCT of GBV-C in a large cohort of GBV-C-HIV-coinfected pregnant women in Thailand.

Reduced mother-to-child transmission of HIV associated with infant but not maternal GB virus C infection.

Background: Prolonged coinfection with GB virus C (GBV-C) has been associated with improved survival in human immunodeficiency virus (HIV)-infected adults. We investigated whether maternal or infant GBV-C infection was associated with mother-to-child transmission (MTCT) of HIV-1 infection.

Methods: The study population included 1364 HIV-infected pregnant women enrolled in 3 studies of MTCT of HIV in Bangkok, Thailand (the studies were conducted from 1992-1994, 1996-1997, and 1999-2004, respectively).

Physician peer assessments for compliance with methadone maintenance treatment guidelines.

Introduction: Medical associations and licensing bodies face pressure to implement quality assurance programs, but evidence-based models are lacking. To improve the quality of methadone maintenance treatment (MMT), the College of Physicians and Surgeons of Ontario, Canada, conducts an innovative quality assurance program on the basis of peer assessments. Using data from this program, we assessed physician compliance with MMT guidelines and determined whether physician factors (e.

Amino acid, mineral and fatty acid content of pumpkin seeds (Cucurbita spp) and Cyperus esculentus nuts in the Republic of Niger.

Dried seeds and nuts are widely consumed by indigenous populations of the western Sahel, especially those who inhabit rural areas. In light of the need for quantitative information regarding the content of particular nutrients in these plant foods, we collected dried pumpkin (Cucurbita spp) seeds and nuts of Cyperus esculentus in the Republic of Niger and analyzed them for their content of essential amino acids, minerals and trace elements, and fatty acids. On a dry weight basis, pumpkin seed contained 58.

Longitudinal trends in antiretroviral use in a cohort of men and women in Ontario, Canada.

Initial studies have shown impaired access to antiretrovirals and slower adoption of new therapies by women. It is unclear if similar treatment delays still occur, especially in those with a publicly funded health care system in Ontario, Canada. The objectives of this study were (1) to evaluate longitudinal patterns of antiretroviral use in patients with HIV in Ontario and (2) to determine if gender differences exist in access to and uptake of antiretroviral drugs over time.

Nutrient content of four edible wild plants from west Africa.

Non-cereal plant foods in the Western Sahel of Africa contribute significantly to the diets of local residents, especially during periods of grain shortages. In this paper, we analyze four such plant foods including diyan kwakwa (nut of coconut palm, Cocos nucifera L.), muricin giginya (young shoot of Borassus aethiopum), tsamiya biri (fruit of the tree, Tamarindus indica), and yari (a mixture of lichens, mainly Rimelia reticulate) that grows on ebony trees (Diospyros mespiliformis).

Factors predicting 2-year retention in methadone maintenance treatment for opioid dependence.

Factors predicting 2-year retention in methadone maintenance and the impact of repeat treatment episodes on retention are examined. Data (n=9555 episodes) were drawn from a population-based treatment registry and analyses were performed using episode-weighted data. We estimated a binary logistic regression model with a duration of 730 days or greater as the dependent variable.

Policy changes and the methadone maintenance treatment system for opioid dependence in Ontario, 1996 to 2001.

Background: Until recently, the availability of methadone treatment in Ontario, Canada was limited. In 1996, policy changes were introduced to increase the availability of treatment. The 5-year impact of these policy changes is assessed.

Polypharmacy in HIV: impact of data source and gender on reported drug utilization.

Drug use in HIV is complex and may involve multiple therapeutic and nontherapeutic agents including prescription, over-the-counter, complementary and alternative medicine, and social/recreational drugs. This study was designed to assess the extent of such drug use in HIV-infected men and women. One hundred four adults were recruited through the HIV Ontario Observational Database from HIV outpatient clinics throughout Ontario, Canada.

Medicinal and recreational marijuana use by patients infected with HIV.

The goal of this study was to describe and compare the prevalence, predictors and patterns of marijuana use, specifically medicinal marijuana use among patients with HIV in Ontario, Canada. Any marijuana use in the year prior to interview and self-defined medicinal use were evaluated. A cross-sectional multicenter survey and retrospective chart review were conducted between 1999 and 2001 to evaluate overall drug utilization in HIV, including marijuana use.

Pushing the boundaries of outreach work: the case of needle exchange outreach programs in Canada.

In this paper, we examine the challenges of defining the boundaries of outreach work using the example of needle exchange programs. In particular, we examine the multiple and inter-related factors that extend needle exchange outreach work beyond its official mandate. Using semi-structured interviews, 59 workers at 15 programs in Ontario, Canada were asked questions about operational policies and routines.
