Suspect screening and prioritization of chemicals of concern (COCs) in a forest-water reuse system watershed.

Much research has assessed organic chemicals of concern (COCs) in municipal wastewater and receiving waters, but few studies have examined COCs in land treatment systems. Many prior studies have implemented targeted methods that quantify a relatively small fraction of COCs present in wastewater and receiving waters. This study used suspect screening to assess chemical features in ground- and surface waters from a watershed where secondary-treated wastewater is irrigated onto 900 ha of temperate forest, offering a more holistic view of chemicals that contribute to the exposome.

Survey of practitioners handling slow lorises (Primates: ): an assessment of the harmful effects of slow loris bites.

Slow lorises () are one of six venomous mammals, and the only known venomous primate. In the wild envenomation occurs mainly during conspecific competition for mates and territory, but may also be used as an application against parasites or for predator defense. Envenomation in humans is documented, with the most extreme accounts detailing near-fatal anaphylactic shock.

A community-engaged infection prevention and control approach to Ebola.

The real missing link in Ebola control efforts to date may lie in the failure to apply core principles of health promotion: the early, active and sustained engagement of affected communities, their trusted leaders, networks and lay knowledge, to help inform what local control teams do, and how they may better do it, in partnership with communities. The predominant focus on viral transmission has inadvertently stigmatized and created fear-driven responses among affected individuals, families and communities. While rigorous adherence to standard infection prevention and control (IPC) precautions and safety standards for Ebola is critical, we may be more successful if we validate and combine local community knowledge and experiences with that of IPC medical teams.

Y-chromosome analysis reveals genetic divergence and new founding native lineages in Athapaskan- and Eskimoan-speaking populations.

For decades, the peopling of the Americas has been explored through the analysis of uniparentally inherited genetic systems in Native American populations and the comparison of these genetic data with current linguistic groupings. In northern North America, two language families predominate: Eskimo-Aleut and Na-Dene. Although the genetic evidence from nuclear and mtDNA loci suggest that speakers of these language families share a distinct biological origin, this model has not been examined using data from paternally inherited Y chromosomes.

Impact of community-based interventions on condom use in the Tłįcho region of Northwest Territories, Canada.

Background: Since 2005, the Tłįcho Community Services Agency (TCSA) in Canada's Northwest Territories (NT) has addressed rising rates of sexually transmitted infections (STI). In 2009, STI rates in the NT were ten times higher than the national rate and Tłįcho regional rates were nearly four times that of the NT--91 cases per 1000 people. We describe a social audit process that assessed the impact of an evidence-based community-led intervention.

Community-coordinated Research as HIV/AIDS Prevention Strategy in Northern Canadian Communities.

The Tłįchǫ Community Services Agency's (TCSA) Healing Wind Strategy identifies a number of activities and interventions to address the prevention of STI/HIV/AIDS in the Tłįchǫ region of the Northwest Territories of Canada. As a part of this strategy, the TCSA and CIET facilitated research to develop a foundation for interventions targeting sexually transmitted infections. The project recruited and trained community-based researchers who conducted a research survey on sexual health attitudes and behaviours in the four Tłįchǫ communities, covering 65% of the population above 9 years of age.

Knowledge profiling as emergent theory in community-based participatory research.

Background: Many sources of valid knowledge may be relevant to a research question. Communities need a mechanism to explore the full range of knowledge that could enrich community-based research. A knowledge profile (KP) is an integrated description of the knowledge and expertise that, once assembled, can help to explore a research issue.
