A highly selective Hg colorimetric sensor and antimicrobial agent based on green synthesized silver nanoparticles using extract.

Plasmonic nanoparticles such as Ag have gained great interest in the biomedical domain and chemical analysis due to their unique optical properties. Herein, we report a simple, cost-effective, and highly selective colorimetric sensor of mercury(ii) based on (horsetail) extract-functionalized Ag nanoparticles (ED-AgNPs). The ED-AgNPs were synthesized by exploiting the coordination of Ag with the various functional groups of ED extract under sunlight exposure for only tens of seconds.

Comparing the scopes of practice of geriatric-focused physicians in Canada: a qualitative study of core competencies.

Background: Given long-standing deficits of medical expertise to care for a growing population of older adults, it is important to understand the geriatric medical workforce. We aimed to describe and compare the scopes of practice of the 3 geriatric-focused physician providers in Canada (i.e.

Nursing Home Resident Admission Characteristics and Potentially Preventable Emergency Department Transfers.

Objectives: To determine which nursing home (NH) resident-level admission characteristics are associated with potentially preventable emergency department (PPED) transfers.

Design: We conducted a population-level retrospective cohort study on NH resident data collected using the Resident Assessment Instrument-Minimum Data Set Version 2.0 and linked to the National Ambulatory Care Reporting System for ED transfers.

Are residents of downtown Toronto influenced by their urban neighbourhoods? Using concept mapping to examine neighbourhood characteristics and their perceived impact on self-rated mental well-being.

Background: There is ample evidence that residential neighbourhoods can influence mental well-being (MWB), with most studies relying on census or similar data to characterize communities. Few studies have actively investigated local residents' perceptions.

Methods: Concept mapping was conducted with residents from five Toronto neighbourhoods representing low income and non-low income socio-economic groups.

Development of a framework for effective community engagement in Ontario, Canada.

Objectives: This study aims to: (1) conceptualize effective community engagement (CE) within the Local Health Integration Networks (LHIN) of Ontario, Canada, (2) develop an effective CE framework and (3) compare the CE framework to public engagement (PE) frameworks and assess their relevance to the LHIN context.

Methods: We implemented "concept mapping," a participatory, mixed-methods approach, with LHIN staff. The method includes three components: (1) "Brainstorming" where participants generated statements describing effective CE; (2) "Sorting and Rating" where participants grouped statements and rated their relative importance to generate a "cluster map" and (3) "Mapping" where participants reviewed and named the clusters to yield the effective CE framework.

Standardized observation of neighbourhood disorder: does it work in Canada?

Background: There is a growing body of evidence that where you live is important to your health. Despite numerous previous studies investigating the relationship between neighbourhood deprivation (and structure) and residents' health, the precise nature of this relationship remains unclear. Relatively few investigations have relied on direct observation of neighbourhoods, while those that have were developed primarily in US settings.

Language impairment and sexual assault of girls and women: findings from a community sample.

Both children and adults with disabilities face increased prevalence of abuse and assault, including sexual assault. Women and girls are disproportionately the victims of sexual assault in both disabled and nondisabled populations. Communication difficulties have been identified as a factor that may increase the vulnerability of individuals with disabilities to sexual assault.
