We identify the ways the policies of leading international bioethics journals limit the participation of researchers working in the resource-constrained settings of low- and middle-income countries (LMICs) in the development of the field of bioethics. Lack of access to essential scholarly resources makes it extremely difficult, if not impossible, for many LMIC bioethicists to learn from, meaningfully engage in, and further contribute to the global bioethics discourse. Underrepresentation of LMIC perspectives in leading journals sustains the hegemony of Western bioethics, limits the presentation of diverse moral visions of life, health, and medicine, and undermines aspirations to create a truly "global" bioethics.

Background: Evidence from systematic reviews of observational studies suggest that hormone replacement therapy (HT) may have beneficial effects in reducing the incidence of cardiovascular disease (CVD) events in post-menopausal women. This is an updated version of a Cochrane review first published in 2005 (Gabriel-Sanchez 2005).

Objectives: To assess the effects of HT for the prevention of CVD in post-menopausal women, and whether there are differential effects between use of single therapy alone compared to combination HT and use in primary or secondary prevention.

Introduction: in 2007 the National Institute of Health and Clinical Excellence (NICE) restricted the use of acetylcholinesterase inhibitors and memantine.

Methods: we conducted a health technology assessment (HTA) of the effectiveness and cost-effectiveness of donepezil, galantamine, rivastigmine and memantine for the treatment of AD to re-consider and up-date the evidence base used to inform the 2007 NICE decision. The systematic review of effectiveness targeted randomised controlled trials.

Background: Psychological symptoms are strongly associated with coronary heart disease (CHD), and many psychological treatments are offered following cardiac events or procedures.

Objectives: Update the existing Cochrane review to (1) determine the independent effects of psychological interventions in patients with CHD (principal outcome measures included total or cardiac-related mortality, cardiac morbidity, depression, and anxiety) and (2) explore study-level predictors of the impact of these interventions.

Search Strategy: The original review searched Cochrane Controleed Trials Register (CCTR, Issue 4, 2001), MEDLINE, EMBASE, PsycINFO, and CINAHL to December 2001.

Background: Although meta-analyses of randomized controlled trials (RCTs) of salt reduction report a reduction in the level of blood pressure (BP), the effect of reduced dietary salt on cardiovascular disease (CVD) events remains unclear.

Methods: We searched for RCTs with follow-up of at least 6 months that compared dietary salt reduction (restricted salt dietary intervention or advice to reduce salt intake) to control/no intervention in adults, and reported mortality or CVD morbidity data. Outcomes were pooled at end of trial or longest follow-up point.

Electronic database search strategies have developed substantially over the course of the past two decades, but their optimal use within a broader search strategy remains unclear. This article evaluates the use of a range of search strategies to identify qualitative evidence on the implementation of cardiovascular disease (CVD) prevention programs. Within the time-limited context of the production of a policy-relevant systematic review, the authors found the protocol-driven, targeted, and reference-checking search strategies to be the most effective, while obtaining authors' suggestions proved to be a resource-intensive process with negligible results.

In children under the age of five, the majority of unintentional injuries occur in the home, with higher levels of injury morbidity and mortality being found among those from more deprived backgrounds. This paper presents the findings of a systematic review about the effectiveness of programmes in decreasing unintentional injury rates to children (aged up to 15 years) in the home. The effectiveness of the provision of home safety equipment with or without installation, safety education or a home risk assessment is presented by outcome: injury rates, installation of smoke alarms and installation of other home safety equipment.

Background: Cardiac rehabilitation is an important component of recovery from coronary events but uptake and adherence to such programmes are below the recommended levels. This aim is to update a previous non-Cochrane systematic review which examined interventions that may potentially improve cardiac patient uptake and adherence in rehabilitation or its components and concluded that there is insufficient evidence to make specific recommendations.

Objectives: To determine the effects of interventions to increase patient uptake of, and adherence to, cardiac rehabilitation.

Aims: To determine the effect of exercise training on clinical events and health-related quality of life (HRQoL) of patients with systolic heart failure.

Methods And Results: We searched electronic databases including Medline, EMBASE, and Cochrane Library up to January 2008 to identify randomized controlled trials (RCTs) comparing exercise training and usual care with a minimum follow-up of 6 months. Nineteen RCTs were included with a total of 3647 patients, the majority of whom were male, low-to-medium risk, and New York Heart Association class II-III with a left ventricular ejection fraction of <40%.

Background: From previous systematic reviews and meta-analyses there is consensus about the positive effect of exercise training on exercise capacity; however, the effects on health-related quality of life, mortality and hospital admissions in heart failure remain uncertain.

Objectives: To update the previous systematic review which determined the effectiveness of exercise-based interventions on the mortality, hospitalisation admissions, morbidity and health-related quality of life for patients with systolic heart failure.

Search Strategy: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 4).
