Background: High blood pressure, excess weight and sedentary lifestyle are important risk factors for cardiovascular diseases, and they are closely associated.

O objetivo deste estudo foi avaliar a prevalência de desmame precoce e fatores associados em crianças atendidas na Estratégia Saúde da Família. Trata-se depesquisa quantitativa, descritiva e exploratória realizada com 241 crianças atendidas pela equipe de saúde. Para coleta dos dados foram usados um formulário e um questionário. Nas análises, para variáveis em que foram encontradas associações estatisticamente significativas foi realizado teste de regressão logística binária. A prevalência de desmame precoce foi de 58,51%. Maiores proporções de desmame precoce ocorreram em crianças com idade entre um e três meses. Pertencer a classe econômica B/C e ter recebido orientação sobre amamentação no pré-natal apresentaram-se significativamente associados com o desmame precoce. A prevalência do desmame precoce foi elevada, e considerada semelhante à prevalência nacional e descrita para o estado do Piauí. Houve associação entre o desmame precoce, classe econômica B/C e ter recebido orientação sobre amamentação no pré-natal.

The present study aimed to investigate the gastroprotective activity of carvacrol, a monoterpene present in essential oils from several species of medicinal and aromatic plants, by using different models of acute gastric lesions in rodents and also evaluate possible mechanisms involved in this action. For this study, absolute ethanol-, acidified ethanol-, ischemia and reperfusion-, and nonsteroidal anti-inflammatory drug-induced models of gastric lesions in mice and rats were used. The roles of nonprotein sulfhydryl groups, catalase, nitric oxide (NO), ATP-sensitive potassium channels (K(ATP) channels), and prostaglandins in carvacrol-induced gastroprotective effect were investigated. In addition, the effects of carvacrol on gastric secretion and mucus in pylorus-ligated rats were also determined. The results of the present study demonstrated that carvacrol promoted a marked gastroprotection in all models investigated, possibly mediated by endogenous prostaglandins, increase of mucus production, K(ATP) channels opening, NO synthase activation, and antioxidant properties. These findings markedly substantiate further studies to investigate the therapeutic potential of carvacrol as an effective gastroprotective agent and its safety profile in medicinal use.

Objective: To analyze the knowledge of breastfeeding (BF) and supplementary feeding (SF) of professionals in the Primary Health Care. Method: Cross-sectional study, with 168 professionals, conducted between June and September 2016. The Kruskal Wallis test was used to compare means of percentage of knowledge about BF and SF, by professional category and contingency testing, for association between variables. Results: From the total of professionals, 39.29% of them demonstrated good knowledge about BF and 2.38% about SF; 74.4% of respondents reported not knowing the program Brazilian Breastfeeding and Feeding Strategy (EAAB – Estratégia Amamenta e Alimenta Brasil). There was a positive association between professionals’ level of knowledge about BF and education (p=0.04), occupation (p=0.05) and healthcare in BF (p=0.04). Regarding the level of knowledge about SF, there was association between education (p<0.01) and healthcare in SF (p=0.04). Conclusion: The professionals have greater knowledge about breastfeeding when compared to supplementary feeding.

We investigated the hypocholesterolemic and liver-protective effects of cooked and germinated whole mung beans. Hamsters were fed for 28 days on diets rich in saturated fatty acids and cholesterol, differing only in protein source (20%): casein, cooked whole mung bean, and germinated mung bean. After 28 days, we found reduced plasma concentrations of total cholesterol and non-HDL cholesterol, increased faecal cholesterol excretion, and reduced levels of asparagine aminotransferase and alanine aminotransferase enzymes in the liver. Reduction in hepatic lipid deposition was observed between each of the mung bean groups relative to the casein group. In addition, the animals of the geminated mung bean group showed a lack of inflammatory infiltrate and better vascularisation of the hepatic tissue. Results from this study show significant hypocholesterolemic and liver-protective properties of the mung bean, which are further enhanced after germination.

The aim of the work was evaluate the effects of testosterone undecanoate (TU) treatment combined with moderate physical training on: the estrous cycle, body weight (BW), motor behavior (MB), and the morphohistology of the reproductive system, the liver and kidney in rats. Female Wistar rats (180 g -250 g) were divided as follows: sedentary + TU (S + TU), trained + TU (T + TU), sedentary + vehicle (S + V), trained + vehicle (T + V). The rats swam 50 min/Day, strapped with a 5% BW load, for 4 weeks. During this training, (BW) was monitored daily as well as the estrous cycle (EC) by vaginal smear. The TU (15 mg/kg s.c) was administered 3 times/week for 4 weeks. At the end of the study, data on MB, BW and morphohistopathological changes in viscera were compiled. The (T + TU) group had on average, a higher (BW) in the fourth week compared to the first week, and (BW) higher than (S + V) and (S + TU) groups. We noted an interruption in the EC and a decrease in weight of ovaries in animals treated with TU. In addition, there was an increase in the relative weight of the heart in groups (T + V) and (T+ TU), and kidneys in group (T + TU). Histopathological analysis showed periportal congestion and isolated foci of hepatic necrosis in rats with TU. Thus, TU combined with training abolished the EC, promoted ovarian atrophy, liver necrosis, cardiac hypertrophy and a decrease in motor activity.Uniterms: Androgenic anabolic steroids/experimental study.

Ratas Wistar (180 a 250 g) foram divididas em: sedentárias + UT (S+UT), treinadas + UT (T+UT), sedentárias + veículo (S+V), treinadas + veículo (T+V). As ratas nadaram 50 min/dia com sobrecarga de ~5% do peso corporal por 4 semanas. Durante o período de treinamento foi realizado acompanhamento diário do peso corporal (PC) e do ciclo estral (CE) pelo esfregaço vaginal. O UT (15 mg/kg s.c.) foi administrado 3x/semana durante 4 semanas. Ao final foram avaliados comportamento motor, pesos e alterações histopatológicas de alguns órgãos. O grupo T+UT apresentou PC maior na quarta semana do que na primeira, com pesos corporais maiores que os grupos S+V e S+UT. Houve interrupção no CE e redução do peso dos ovários nos animais tratados com UT. Houve aumento do peso relativo do coração, nos grupos T+V e T+UT, e do peso relativo dos rins, no grupo T+UT. A análise histopatológica revelou congestão periportal e focos isolados de necrose hepática nas ratas com UT. O UT combinado com treinamento produziu supressão do ciclo estral, atrofia ovariana, necrose hepática, hipertrofia cardíaca e redução da atividade motora.Unitermos: Esteróides androgênicos anabólicos/estudo experimental.

The acute toxicity, the antioxidant activity, and the pharmacological activity on the gastrointestinal tract of rodents of the ethanolic extract (TFEE) from the bark of Terminalia fagifolia Mart. & Zucc. (Combretaceae) and of its aqueous (TFAqF), hydroalcoholic (TFHAF), and hexanic (TFHEXF) partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.
