Randomized Controlled Trial
Effects of Rubus occidentalis extract on blood pressure in patients with prehypertension: Randomized, double-blinded, placebo-controlled clinical trial.
Black raspberry (Rubus occidentalis) is known for improving vascular function. However, there has been no study evaluating its effects on 24-h systolic and diastolic blood pressure in prehypertensive patients. The aim of this study was to examine those effects. ⋯ The use of black raspberry significantly lowered 24-h BP in prehypertensive patients during the 8-wk follow-up. Black raspberry used as a dietary supplement could be beneficial in reducing SBP in prehypertensive patients.

To systematically review the published evidence regarding the association between Mg intake and serum concentrations with MetS and, if possible, to summarize the results using a meta-analysis. ⋯ The present systematic review and meta-analysis found an inverse association between Mg intake and MetS. However, the inverse association for serum Mg levels was highly heterogeneous and sensitive. The link between Mg status and MetS should be confirmed by prospective cohort studies controlling the association for other nutrients related to MetS risk.

This study aimed to evaluate the relationship between lung function and body composition in cystic fibrosis (CF) and examine the presence of normal-weight obesity (NWO), a high body fat percentage with a normal body mass index (BMI), in this population. ⋯ Excess adiposity, particularly in the form of NWO, was inversely associated with lung function in CF. Larger prospective studies should be undertaken to confirm these findings and determine the long-term metabolic and clinical consequences of excess adiposity in CF. As the lifespan of individuals with CF increases, nutrition screening protocols, which primarily rely on BMI, may require reassessment.

To determine whether overweight or obesity between 0 and 6 y increases the probability of developing general/central obesity at 7 y. ⋯ There is tracking not only of obesity but also of overweight after birth for developing general or central obesity at 7 y. Prevention should begin very early on.

Serum folate levels and fatality among diabetic adults: A 15-y follow-up study of a national cohort.
Folate is involved in carbohydrate metabolism, a process that can have clinical implications regarding diabetes management. The aim of this study was to assess the relationship between serum folate and fatality among adults with diabetes. ⋯ Results indicate that high serum folate concentrations are associated with an increased fatality risk among adults with diabetes. Further studies are warranted to determine the mechanism(s) of this phenomenon.
