Review Meta Analysis
Effect of increased potassium intake on cardiovascular risk factors and disease: systematic review and meta-analyses.
To conduct a systematic review of the literature and meta-analyses to fill the gaps in knowledge on potassium intake and health. ⋯ High quality evidence shows that increased potassium intake reduces blood pressure in people with hypertension and has no adverse effect on blood lipid concentrations, catecholamine concentrations, or renal function in adults. Higher potassium intake was associated with a 24% lower risk of stroke (moderate quality evidence). These results suggest that increased potassium intake is potentially beneficial to most people without impaired renal handling of potassium for the prevention and control of elevated blood pressure and stroke.

To evaluate studies assessing the effectiveness of a bundle of nasal decolonization and glycopeptide prophylaxis for preventing surgical site infections caused by Gram positive bacteria among patients undergoing cardiac operations or total joint replacement procedures. ⋯ Surgical programs that implement a bundled intervention including both nasal decolonization and glycopeptide prophylaxis for MRSA carriers may decrease rates of surgical site infections caused by S aureus or other Gram positive bacteria.

Review Meta Analysis
Dietary fibre intake and risk of cardiovascular disease: systematic review and meta-analysis.
To investigate dietary fibre intake and any potential dose-response association with coronary heart disease and cardiovascular disease. ⋯ Greater dietary fibre intake is associated with a lower risk of both cardiovascular disease and coronary heart disease. Findings are aligned with general recommendations to increase fibre intake. The differing strengths of association by fibre type or source highlight the need for a better understanding of the mode of action of fibre components.
