Randomized Controlled Trial
Effects of extra virgin olive oil and fish oil on lipid profile and oxidative stress in patients with metabolic syndrome.
The aim of this study was to verify if extra virgin olive oil and fish oil have a synergistic effect on lipid and oxidative stress parameters in patients with metabolic syndrome (MetS). ⋯ The present study provides evidence that increased dietary ω-3 polyunsaturated fatty acids and extra virgin olive oil have beneficial synergistic effects on lipid metabolism and oxidative stress in patients with MetS.

The Global Burden of Disease Study and related studies report unhealthy diet is the leading risk for death and disability globally. Given the evidence associating diet and non-communicable diseases (NCDs), international and national health bodies including the World Health Organization and United Nations have called for population health interventions to improve diet as a means to target NCDs. One of the proposed interventions is to ensure healthy foods/beverages are more accessible to purchasers and unhealthy ones less accessible via fiscal policy, namely taxation and subsidies. ⋯ The quality, level and strength of evidence along with identified gaps in research support the need for further policies and ongoing evaluation of population-wide food/beverage subsidies and taxation. To maximize success and effect, this review suggests that food taxes and subsidies should be a minimum of 10 to 15% and preferably used in tandem. Implementation of population-wide polices for taxation and subsides with ongoing evaluation of intended and unintended effects are supported by this review.

Review Meta Analysis
Yogurt for treating antibiotic-associated diarrhea: Systematic review and meta-analysis.
Antibiotic-associated diarrhea (AAD) is a common complication in individuals treated with antibiotics. The aim of this review was to systematically evaluate the efficacy of yogurt consumption for the prevention of AAD. ⋯ Given the simple nature of the intervention, the scarcity of data is noteworthy. No consistent effect of yogurt consumption for preventing AAD was shown. However, the data are limited and the included trials had methodological limitations. Results from large, rigorously designed RCTs are needed to assess the effect of yogurt consumption on AAD prevention.

Vitamin D has pleiotropic effects on cardiac, renal, and endocrine diseases like diabetes mellitus and deficiency has been correlated with increased Intensive Care Unit (ICU) morbidity and mortality. We studied the relationship between preoperative Vitamin D levels and several short-term endpoints including cardiovascular events, glucose levels, ICU, and hospital length of stay. ⋯ The low levels in this study truly represent the Vit D status as they were obtained before any intervention, including surgery or fluid administration. Vit D levels decreased rapidly after surgery and hence future studies on Vit D may need to focus on premorbid levels obtained at the time of initial presentation and not those obtained after resuscitation or ICU admission. In contrast to epidemiologic reports, we found no association between low Vit D levels and postoperative cardiovascular events. However, low Vit D levels did affect the ICU and hospital length of stay in patients who were undergoing cardiac surgery. This is an important finding especially when many institutions and regulatory agencies are investigating novel therapies and processes to reduce the length of hospitalization. More studies are required to investigate the effect on hospital length of stay of early preadmission or preoperative Vit D supplementation before elective surgery.

The aim of this study was to identify metabolically healthy obese individuals (MHOs) and their characteristics, as well as to estimate cardiovascular risk using the Framingham score. ⋯ MHOs had biochemical and anthropometric characteristics, such as lower body mass index, waist circumference, percent fat mass, glucose, triacylglycerols, and increased high-density lipoprotein, that made them different from those individuals classified as MUO. The latter exhibited increased risk for cardiovascular disease according to the Framingham score, when using the ATP III criterion alone or in conjunction with the HOMA index.
