Evaluation of a training program for medicines-oriented policymakers to use a database of systematic reviews.

Background: Suboptimal prescribing and medications use is a problem for health systems globally. Systematic reviews are a comprehensive resource that can help guide evidence-informed decision-making and implementation of interventions addressing such issues; however, a barrier to the use of systematic reviews is their inaccessibility (due to both dispersion across journals and inaccessibility of content). Publicly available databases, such as Rx for Change, provide quick access to summaries of appraised systematic reviews of professional and consumer-oriented interventions to improve prescribing behaviour and appropriate medication use, and may help maximise the use of evidence to inform decisions.

Development of training for medicines-oriented policymakers to apply evidence.

Background: Health systems globally promote appropriate prescribing by healthcare providers and safe and effective medicine use by consumers. Rx for Change, a publicly available database, provides access to systematic reviews regarding best practices for prescribing and using medicines. Despite the value of the database for improving prescribing and medicine use, its use remains suboptimal.

"Fishing" for the origins of the "Eskimos and heart disease" story: facts or wishful thinking?

During the 1970s, 2 Danish investigators, Bang and Dyerberg, on being informed that the Greenland Eskimos had a low prevalence of coronary artery disease (CAD) set out to study the diet of this population. Bang and Dyerberg described the "Eskimo diet" as consisting of large amounts of seal and whale blubber (ie, fats of animal origin) and suggested that this diet was a key factor in the alleged low incidence of CAD. This was the beginning of a proliferation of studies that focused on the cardioprotective effects of the "Eskimo diet.

What is the feasibility of implementing effective sodium reduction strategies to treat hypertension in primary care settings? A systematic review.

Objective: To evaluate whether efficacious counseling methods on sodium restriction can be successfully incorporated into primary care models for the management of hypertension.

Methods: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects and Health Technology Assessment to identify randomized controlled trials of dietary counseling for salt intake reduction that reported significant reduction in 24-h urinary sodium and blood pressure levels among adults with untreated hypertension. Data extraction and assessment of reproducibility and feasibility were done in duplicate and any disagreements were resolved by consensus.

Population-based versus high-risk strategies for the prevention of cardiovascular diseases in low- and middle-income countries.

Cardiovascular diseases (CVD) are now the number one cause of death in low- and middle-income countries (LMIC), such as those in South East Asia (SEA). It is projected that SEA countries will have the greatest total number of deaths due to non-communicable diseases (NCDs) by 2020. In low resource countries, the rising burden of CVDs imposes severe economic consequences that range from impoverishment of families to high health system costs and the weakening of country economies.

A cross-national comparative study of blood pressure levels and hypertension prevalence in Canada and Hungary.

Purpose: Hungary has one of the highest cardiovascular (CV) mortality and stroke rates compared to other countries in Europe and North America. Data from two recent blood pressure (BP) screening projects in Hungary and Canada provided us with the opportunity to compare potential differences in the prevalence of hypertension between these countries.

Methods: From the Ontario Blood Pressure Survey, 880 white Canadians between 20 and 62 years old with white-collar occupation were selected and compared with a total of 1000 Hungarian bank employees in the same age range.

High prevalence of prehypertension and hypertension in a working population in Hungary.

Background: Hungary has one of the highest mortality rates due to strokes among the European Union countries. As elevated blood pressure (BP) is the principal risk factor for strokes, we assessed BP levels, as well as awareness and treatment status of hypertension and prehypertension in a working population sample in Hungary.

Methods: Worksite employees in Budapest and Szeged were screened for their BP using an automated BP measuring instrument (BpTRU).

Time trends in cardiovascular and all-cause mortality in the 'old' and 'new' European Union countries.

Aims: There are large differences in all-cause and cardiovascular disease (CVD) mortality between eastern and western countries in Europe. We reviewed the development of these mortality trends in countries of the European Union (EU) over the past 40 years and evaluated available data regarding possible determinants of these differences.

Methods And Results: We summarized all-cause mortality and specific cardiovascular mortality for two country groups - 10 countries that joined the European Union (EU) after 2004 (East), and 15 countries that joined before 2004 (West).

Lifestyle changes and blood pressure control: a community-based cross-sectional survey (2006 Ontario Survey on the Prevalence and Control of Hypertension).

To evaluate lifestyle changes and their impact on hypertension control in a sample of hypertensive respondents in Ontario, Canada, diet, physical activity, and other nonpharmacologic measures were recorded using a structured questionnaire during the 2006 Ontario Survey on the Prevalence and Control of Hypertension. Responses were weighted to the total adult population of 7,996,653 in Ontario. The prevalence of hypertension was 21%; 42% of hypertensive persons received therapy with antihypertensive drugs and lifestyle changes, and 41% received therapy with drugs only.

2006 Ontario Survey on the Prevalence and Control of Hypertension (ON-BP): rationale and design of a community-based cross-sectional survey.

Background: The presently available Canadian data, based on direct measurements of blood pressure (BP) from the Canadian Heart Health Surveys, are more than 15 years old. In view of major changes in the demographics and health status of the Ontario population, there is an urgent need to update this information. On the initiative of the Heart and Stroke Foundation of Ontario, the University of Ottawa Heart Institute, jointly with Statistics Canada, designed and implemented a population-based cross-sectional survey of hypertension in the Province of Ontario: the 2006 Ontario Survey on the Prevalence and Control of Hypertension (ON-BP).
