Objective: To evaluate the use of biofeedback intervention in the levels of depression. The main hypothesis tested if the use of biofeedback improves depression levels compared to the control group., Methods: A randomised clinical trial. The final sample was composed of 36 participants (18 in the experimental group, receiving 6 training, once a week, with biofeedback; and 18 in the control group, who received conventional treatment in the service).Outcome measures were assessed in two stages: pre-test and post-test. The research used the following instruments: demographic survey data, Mini International Neuropsychiatric Interview 5.0.0 and Beck Depression Inventory (BDI). The factors and variables were presented in terms of descriptive and inferential statistics. Fisher's exact test (p < 0.05) was used to verify the existence of an association between the counting variables. The multinomial logistic regression model was adopted, and the Logit link function was used, as the software RStudio version 3.6.2., Results: The factors that remained in the final model were group, sex, partner, atypical antidepressant, benzodiazepines, mood stabiliser, antiepileptic and antihistamine, according to the levels of depression based on the BDI. The group that did not receive biofeedback intervention had 16 times more chances of increasing the depression levels compared to participants in the experimental group., Conclusion: The use of biofeedback reduces depression, thus, representing a complementary alternative for the treatment of moderate and severe depression, and dysthymia.

This paper aimed to evaluate the influence of seasonality on the chemical composition of oysters (Crassostrea rhizophorae). Samples were collected during summer and winter from the estuary and lagoon complex of the municipality of Barra de São Miguel, Alagoas, Brazil. Statistical differences (p<0.05) between summer and winter were observed in relation to chemical composition. The oysters cultivated in the winter presented some nutritional advantages because of the higher levels of proteins and functional nutrients, such as the eicosapentaenoic-docosahexaenoic acid combination and percentages of polyunsaturated fatty acids (n-3 and n-6), and the lower levels of saturated fatty acids. Therefore, the animals in winter presented a higher content of cholesterol oxides. The levels of cholesterol oxides found in these products during winter may encourage researchers to investigate the composition of oysters cultivated in different climates all over the world., (Copyright © 2012.

Context and Objective: Compromised maternal mental health (MMH) is considered to be a risk factor for child malnutrition in low income areas. Psychosocial variables associated with MMH are potentially different between urban and rural environments. The aim here was to investigate whether associations existed between MMH and selected sociodemographic risk factors and whether specific to urban or rural settings., Design and Setting: Cross-sectional study on a representative population sample of mothers from the semiarid region of Alagoas., Methods: Multistage sampling was used. The subjects were mothers of children aged up to 60 months. MMH was evaluated through the Self-Reporting Questionnaire-20. Mothers' nutritional status was assessed using the body mass index and waist circumference. Univariate analysis used odds ratios (OR) and chi-square. Logistic regression was performed separately for urban and rural subsamples using MMH as the dependent variable., Results: The sample comprised 288 mothers. The prevalences of common mental disorders (CMD) in rural and urban areas were 56.2% and 43.8%, respectively (OR = 1.03; 95% CI: 0.64-1.63). In univariate analysis and logistic regression, the variable of education remained associated with MMH (OR = 2.2; 95% CI: 1.03-4.6) in urban areas. In rural areas, the variable of lack of partner remained associated (OR = 2.6; 95% CI: 1.01-6.7)., Conclusions: The prevalence of CMD is high among mothers of children aged up to two years in the semiarid region of Alagoas. This seems to be associated with lower educational level in urban settings and lack of partner in rural settings.

Objective: To evaluate the effect of chronic consumption of di- and triheptanoin on hepatic steatosis (HS) in rats., Methodology: Wistar rats were submitted to a diet AIN-93 with 0, 30 or 50% of its oil substituted with an oil rich in di- and triheptanoin, groups TAGC(7)0, TAGC(7)30 and TAGC(7)50 respectively, for nine months. The control group received Labina(R). Liver histology, hepatic lesion and function proofs, glycemia and lipid profile, were performed. Variance analyses, F-test, Dunnet s test and uni- and multivariate regression analyses were performed (p<0.05)., Results: TAGC(7)0, TAGC(7)30 and TAGC(7)50 developed HS; 80% of severe cases in TAGC(7)0, as against 40% in TAGC(7)50. The absolute (ALW) and relative (RLW) liver weights were higher in TAGC(7)0 and TAGC(7)30, and glycemia was greater in TAGC(7)30 and TAGC(7)50, than in the Control. Total cholesterol, LDL-c, LDL-c/HDL-c and total proteins were higher in the Control. The experimental oil reduced RLW and showed a tendency in the reduction of body weight, ALW, percentage of hepatic lipids and the severity of HS. The explanatory variables in relation to HS were final weight, glycemia, albumin, HDL-c, LDL-c, LDL-c/HDL-c, VLDL-c and alkaline phosphatase., Conclusions: It is suggested that di- and triheptanoin have a hepatoprotector effect against HS, in rats, in a dose-dependent manner.

Purpose: to determine the prevalence and risk factors associated to anemia in pregnant women from the semiarid region of Alagoas, Brazil., Methods: transversal study comprising a sample (n=150) obtained taking into consideration the prevalence estimated by World Health Organization of 52%, an error of 8% and a confidence interval of 95%. Sampling has been done in three stages: 15 towns among the 38 in the region, four census sectors by town and 24 residences by sector. All the resident pregnant women were eligible, and their socio-economic, demographic, anthropometric and health data have been collected. Anemia was identified at the <11 g/dL hemoglobin level (Hemocue), and its association with risk factors, tested by multiple linear regression analysis., Results: anemia prevalence was 50%. Seventy eight per cent of the pregnant women were under pre-natal care. From those, 79.3% were in the second or third trimester of gestation. Nevertheless, only 21.2% of them were taking iron supplementation. Variables (p<0.05) independently associated with anemia (anemic versus not-anemic pregnant women) were: larger number of family members (4.5+/-2.3 versus 4,3+/-2.3; p=0.02), lower age group of the pregnant woman (23.9+/-6.3 versus 24.7+/-6.7; p=0.04), or of her partner (34.5+/-15.8 versus 36+/-17.5; p=0.03), no toilet in the house (30.7 versus 24%; p<0.001), history of child abortion and/or death (32.4 versus 16.4%; p<0.001), living in the country (60 versus 46.7%; p=0.03), average per capita income
