Effects of beta-glucans ingestion (Saccharomyces cerevisiae) on metabolism of rats receiving high-fat diet.

We investigated the effects of beta-glucans (Saccharomyces cerevisiae) ingestion on metabolic parameters of Wistar rats receiving high-fat diet. The experimental period was divided into two stages: in the first one, the animals were divided into two groups containing 12 animals each. The first group received commercial feed and the second received high-fat diet containing 20% of pork fat during 60 days. At the end of this period, body weight, blood glucose and Lee index were assessed. In the second stage, those 24 animals were redivided into four groups: (C) - control diet; (CB) - control diet and treated with Beta-glucan (BG); (O) - obese animals and (OB) - obese animals treated with BG. Animals from groups CB and OB received 30 mg/kg of BG dissolved in saline solution by gavage. Animals from groups C and O received only saline solution for 28 days. The design used was totally randomized in 2 × 2 factorial scheme. Data were submitted to analysis of variance (anova). Animals from OB group showed inferior levels (p < 0.05) of total cholesterol (13.33%), triacylglycerols (16.77%) and blood glucose (23.97%) when compared to the animals from group O. The use of BG has provided smaller increase in Lee index (p < 0.05), without promoting alteration in feed and water consumption, organs weight, HDL-C, LDL+VLDL-C, carcass composition, villus/crypt ratio, and pancreas, kidney and stomach histology. BG from S. cerevisiae promoted beneficial metabolic effects in rats receiving high-fat diet.

Common mental disorders in late pregnancy in women who wanted or attempted an abortion.

BACKGROUND: In countries where legal abortion is restricted, many unwanted pregnancies are carried to term. Attempting an unsuccessful abortion may influence women's mental health. This study investigated the common mental disorders (CMDs) of depression and anxiety in the third trimester of pregnancy in women who wanted or had attempted an abortion in a poor region of Brazil. METHOD: CMDs were assessed by using the 20-item Self-Reporting Questionnaire (SRQ-20) in all pregnant women aged 18-49 years who were registered with publicly funded primary health care in Recife, Northeast Brazil. RESULTS: The study achieved a high response rate and 1121 (98.9%) women completed the interview. The prevalence of CMDs for the sample was 43.1% [95% confidence interval (CI) 40.2-46.1], and 63.6% (95% CI 55.4-71.2) among the 13.7% of women who attempted an abortion. The association between CMDs and attempted an abortion [odds ratio (OR) 2.05, 95% CI 1.3-3.1] remained after adjustment for confounders. CONCLUSIONS: This study found that attempting an abortion in the current pregnancy was associated with CMDs. Good access to family planning programs, including access to contraceptive methods and safe abortion, should help to improve the mental health of women.
