Influence of milk yield, stage of lactation, and body condition on dairy cattle lying behaviour measured using an automated activity monitoring sensor.

Time spent lying by lactating Holstein-Friesian cows of varying body condition scores (BCS) and milk yield was measured using an animal activity monitor. A 3-week average BCS was calculated for each cow; and in total, 84 cows were selected with 28 cows each among three BCS categories (Thin: BCS<2.75; Moderate: 2.

Canadian medical students' perceptions of public health education in the undergraduate medical curriculum.

Purpose: To understand the perceptions and attitudes of Canadian medical students toward their undergraduate medical public health curriculum and to identify student suggestions and priorities for curriculum change.

Method: Five focus groups of 11 or 12 medical students from all years of medical school were recruited at McMaster University Faculty of Health Sciences, Université de Sherbrooke Faculty of Medicine and Health Sciences, University of Toronto Faculty of Medicine, University of Manitoba Faculty of Medicine, and University of British Columbia Faculty of Medicine between February and April 2006. A professional facilitator was hired to conduct the focus groups using a unique, computer-based facilitation system.

Assessing Canadian medical students' familiarity with and interest in pursuing a career in community medicine.

Objectives: Following the SARS outbreak, large gaps in the public health workforce have been identified. This study sought to understand the perceptions and attitudes of Canadian medical students with regard to public health to determine how this impacted their choice towards a career in Community Medicine (CM).

Methods: Five focus groups of 11-12 medical students from all years were recruited at McMaster University, Université de Sherbrooke, University of Toronto, University of Manitoba and the University of British Columbia.

Previous creatinine levels safely predict amantadine dose for influenza A outbreak control.

Background: Amantadine, an antiviral agent, is the only drug currently approved in Canada for prophylaxis of influenza A virus infection. To minimize side effects, the amantadine dose is adjusted for age and estimated creatinine clearance (CrCl) based on plasma creatinine (Cr) levels. As amantadine is used more frequently for influenza A outbreak control in care facilities for elderly people, physicians are increasingly called on to prescribe it for residents and to consider the necessity of requesting plasma Cr levels.
