The purpose of this study was to compare the effects of 3 different modalities of exercise on metabolic control, insulin resistance, inflammatory markers, adipocytokines, and tissue expression of insulin receptor substrate (IRS)-1 after 12 weeks of training among patients with type 2 diabetes mellitus. Forty-eight patients with type 2 diabetes mellitus were randomly assigned to 4 groups of training (3 times a week, 60 minutes per session): aerobic group (n = 12), resistance group (n = 12), combined (aerobic and resistance) group (n = 12), and control group (n = 12). Fasting and postprandial blood glucose, glycated hemoglobin, lipid profile, insulin resistance index (homeostasis model assessment of insulin resistance), adipocytokines (adiponectin, visfatin, and resistin), tumor necrosis factor, interleukin, and high-sensitivity C-reactive protein (hs-CRP) were measured at baseline and at the end of the study. Patients also underwent a muscle microbiopsy before and after training to quantify IRS-1 expression. All 4 groups displayed decreases in blood pressure, fasting plasma glucose, postprandial plasma glucose, lipid profile, and hs-CRP (P < .05); and there was no difference across the groups. After training, the IRS-1 expression increased by 65% in the resistance group (P < .05) and by 90% in the combined group (P < .01). Exercise training favorably affects glycemic parameters, lipid profile, blood pressure, and hs-CRP. In addition, resistance and combined training can increase IRS-1 expression.
Orbital vascular impedance reduction with orbital hyperperfusion was present in severe pre-eclamptic women compared with mild pre-eclamptic and healthy pregnant women. Ophthalmic Doppler is a novel parameter that may be useful in the diagnosis of severe pre-eclampsia.
Reference values were generated for ophthalmic artery Doppler measurements, and they did not vary significantly during healthy pregnancy.
ResumoOBJETIVO: Descrever as características maternas e das crianças, bem como avaliar os fatores associados à interrupção do aleitamento materno exclusivo. MÉTODOS: Estudo transversal que incluiu 667 crianças de seis meses que compareceram na Campanha de Multivacinação em Uberlândia, 2008. No delineamento amostral, foram sorteadas as unidades de vacinação e posteriormente as crianças em cada unidade, sistematicamente. Um instrumento semiestruturado foi utilizado para coleta dos dados, formulado com questões sobre alimentação da criança e características sociodemográficas da mãe. Foi utilizado risco relativo e teste do χ 2 para análise dos dados, aceitando como nível crítico p<0,05, com intervalo de confiança de 95%. RESULTADOS: A prevalência do aleitamento materno para os menores de 120 e 180 dias foi de 89,5 e 85%, respectivamente; e na modalidade de aleitamento materno exclusivo, 50,6 e 39,7% para menores de 120 e 180 dias, respectivamente. Os fatores mais associados ao abandono do aleitamento materno exclusivo em menores de seis meses foram o trabalho materno fora de casa (OR=2,7; IC95%=1,7-4,2) e o uso de chupetas (OR=4,2; IC95%=2,8-6,3). O fato de a mãe ser multípara (OR=0,5; IC95%=0,4 -0,81) e recorrer ao atendimento puerperal na rede pública (OR=0,5; IC95%=0,3-0,7) representaram fatores de proteção contra a prática do desmame precoce. CONCLUSÃO: As prevalências do aleitamento materno e aleitamento materno exclusivo no município de Uberlândia estão entre as maiores do país. Os fatores mais frequentemente associados à prática de desmame precoce foram trabalho materno fora de casa, oferta de bicos ou chupetas às crianças, atendimento puerperal efetuado no serviço privado e primiparidade. Abstract PURPOSE:To describe the characteristics of mothers and children and to evaluate the factors associated with discontinuation of exclusive breastfeeding. METHODS: A cross-sectional study on infants under six months of age who attended the vaccination campaign in 2008. In the sample design, vaccination units were selected by drawing lots and infants were similarly selected later at each unit systematically. A semi-structured instrument was used for data collection, containing questions about children's nutrition and socio-demographic characteristics. We used Odds Ratio and the χ 2 test for data analysis, accepting as the critical level p<0.05. RESULTS: The prevalence of breastfeeding for infants under 120 and 180 days of age was 89.5 and 85% respectively, and exclusive breastfeeding was 50.6 and 39.7% for infants less than 120 and 180 days of age, respectively. The factors most related to the abandonment of exclusive breastfeeding in infants under six months were maternal employment outside the home (OR=2.73; 95%CI=1.74-4.29) and use of pacifiers (OR=4.26; 95%CI=2.85-6.38). The mother being multiparous (OR=0.57; 95%CI=0.40-0.81) and receiving postpartum care in the public health care network (OR=0.55; 95%CI=0.39-0.79) represented protective factors against the practice of early cessation of breastfeeding. CONCLUSIONS:...
Pre-eclampsia is a multifactorial and multisystemic disease specific to gestation. It is classically diagnosed by the presence of hypertension associated with proteinuria manifested in a previously normotensive pregnant woman after the 20th week of gestation. Pre-eclampsia is also considered in the absence of proteinuria if there is target organ damage. The present review takes a general approach focused on aspects of practical interest in the clinical and obstetric care of these women. Thus, it explores the still unknown etiology, current aspects of pathophysiology and of the diagnosis, the approach to disease prediction, its adverse outcomes and prevention. Management is based on general principles, on nonpharmacological and on pharmacological clinical treatment of severe or nonsevere situations with emphasis on the hypertensive crisis and eclampsia. Obstetric management is based on preeclampsia without or with signs of clinical and/or laboratory deterioration, stratification of gestational age in < 24 weeks, between 24 and less than 34 weeks, and ≥ 34 weeks of gestation, and guidance on route of delivery. An immediate puerperium approach and repercussions in the future life of pregnant women who develop preeclampsia is also presented.
