OBJECTIVE: to evaluate the structure, process and results of the Capillary Blood Glucose Self-monitoring Program in a Brazilian city. METHOD: epidemiological, cross-sectional study. The methodological framework of Donabedian was used to construct indicators of structure, process and outcome. A random sample (n = 288) of users enrolled and 96 health professionals who worked in the program was studied. Two questionnaires were used that were constructed for this study, one for professionals and one for users, both containing data for the evaluation of structure, process and outcome. Anthropometric measures and laboratory results were collected by consulting the patients' health records. The analysis involved descriptive statistics. RESULTS: most of the professionals were not qualified to work in the program and were not knowledgeable about the set of criteria for patient registration. None of the patients received complete and correct orientations about the program and the percentage with skills to perform conducts autonomously was 10%. As regards the result indicators, 86.4% of the patients and 81.3% of the professionals evaluated the program positively. CONCLUSION: the evaluation indicators designed revealed that one of the main objectives of the program, self-care skills, has not been achieved.

Oxidative stress is related with physiopathology of diabetes mellitus type II and with its secondary complications, such as diabetic nephropathy. Thus, the purpose of this study was to examine the effects of n-acetylcysteine NAC, an antioxidant from Allium cepa, on oxidative stress, morphometrical and nutritional parameters and basal metabolism and energetic substrate utilization, serum glucose and oral glucose tolerance test (OGTT), and renal function of high-sucrose intake rats. Animals were initially divided into three groups. Rats in the control group (C; n=10) were given free access to a standard chow and water; (S; n=10) group received standard chow and 30% sucrose in its drinking water; (SN; n=5) group received standard chow and 2g/L NAC and 30% sucrose in its drinking water. After 25 days of treatments, rats were submitted to indirect calorimetry in fasted and feed states. After 30 days of treatments, rats from C and S groups were divided into four groups of five rats each. The (CC) and (SS) groups were given an intra-gastric dose 0,6mL saline (0,9%NaCl) and the (CNAC) and (SNAC) groups were treated with a intra-gastric dose of 0,6mL NAC (160g/day), and then everybody received a intra-gastric dose of glucose solution (20%) for the OGTT. Animals of S and SN groups have higher liquid consumption and lower food consumption than C group. Calorimetric analyses confirm that despite of the final body weight had not statistical difference among groups, S group have lower resting metabolic rate when compared to C and SN animals. Besides, S group has higher respiratory quotient, higher carbohydrate oxidation and lower lipid oxidation, both in fasted and feed states, than C and SN groups, evidencing the beneficial effect of NAC. Fasting plasma glucose is increased in SS and SNAC animals when compared to CC and CNAC, however SN group has glicemic level at 30 min before OGTT decreased when ...(Complete abstract click electronic access below)

Dezesseis atletas treinados em musculação (grupo AN = 7) ou em corridas de longa distância (AE = 9) foram submetidos a exercícios de máxima intensidade específicos e inespecíficos a sua modalidade de treinamento. A influência da especificidade do treinamento sobre as alterações promovidas por sessões agudas de exercício exaustivo nos parâmetros hemodinâmicos, de dano muscular e de estresse oxidativo foi analisada, e foram comparados os padrões de resposta aos exercícios entre os dois grupos. Os testes máximos consistiram de teste exaustivo em esteira, utilizando protocolo de rampa, e teste com pesos utilizando cargas iniciais de 80% de 1RM, progressivamente reduzidas, até a exaustão, em dois exercícios que abrangeram grupos musculares distintos. Foram realizadas coletas de sangue antes e imediatamente após os exercícios para a determinação de indicadores de hemoconcentração, de lesão muscular, de processo inflamatório e determinação de parâmetros hemogasimétricos. A glicemia se elevou significativamente após os testes somente para o grupo AE. Foram verificados aumentos significativos na acidose devidos a elevação das concentrações de lactato, H+ combinados a redução do HCO3-. Foram observadas variações significativas nas concentrações dos íons sódio e potássio. Também houveram aumentos significativos nas concentrações de CPK e DHL. Além disso, houveram elevações das concentrações plasmáticas e dos leucócitos. Dentro dos parâmetros analisados, as respostas observadas não foram uniformes em comparação aos dois grupos, e houve variação também interna aos grupos, quando comparados os exercícios específicos aos inespecíficos. Os resultados apontam que embora seja esperada uma resposta metabólica característica após o esforço físico exaustivo, a especificidade do treinamento é determinante sobre os processos adaptativos...

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

A hipertensão arterial sistêmica é uma doença crônica degenerativa de etiologia multifatorial e poligênica, caracterizada pela presença de níveis tensionais elevados, sendo considerada um dos mais importantes fatores de risco para o desenvolvimento das doenças cardiovasculares. Estudos demonstram que cerca de um bilhão de indivíduos apresentam HAS em todo mundo, sendo esta patologia responsável por 7,1 milhões de morte a cada ano. Diversos fatores estão associados ao aumento da incidência da hipertensão arterial, como obesidade, dislipidemias, dieta rica em sal, alterações nos níveis hormonais e sedentarismo. Após o período da menopausa, observa-se significativa elevação nos valores de pressão arterial dessa população, sendo estes similares ou até maiores aos dos homens para esse mesmo período. O sistema renina-angiotensina (SRAA) desempenha importante papel no controle dos sistemas cardiovascular e renal e a angiotensina II é um potente vasoconstritor desse sistema, formado a partir da ação da Enzima Conversora de Angiotensina (ECA). Por outro lado, a recente descoberta da Enzima Conversora de Angiotensina 2 (ECA2), um homólogo da ECA, mudou todo o conceito do SRAA. A ECA 2 é responsável pela formação do peptídeo angiotensina- (1-7) a partir da clivagem do último aminoácido (fenilalanina) da angiotensina II. Recentes evidências têm demonstrado efeitos benéficos da angiotensina-(1-7) para as doenças cardiovasculares através da vasodilatação, efeito anti-arritmogênico, melhora na função contrátil pós-isquemia e inibição da proliferação celular do músculo liso vascular, sendo esses efeitos antagônicos àqueles observados pela angiotensina II. Dessa forma, o objetivo desse estudo foi analisar a atividade da ECA2, concentrações plasmáticas...(Resumo completo, clicar acesso eletrônico abaixo)

Adequate testosterone levels are necessary for the development, growth and maintenance of the male reproductive system. Testosterone deficiency is common in men with diabetes in whom it may contribute to impaired performance, with consequent reduction of the activity of the androgen regulated organs, such as the prostate. However, little attention has been given to the plasma dihydrotestosterone (DHT) level, the most potent androgen, nor to the expression of the androgen receptor (AR), insulin-like growth factor type I (IGF-1) and receptor (IGF-1R) in target tissues. Here, we investigated the effect of type I diabetes mellitus on DHT plasma levels and on prostate AR, IGF-1 and IGF-1R expression during rat pubertal growth. Diabetes was induced in prepubertal male rats through administration of streptozotocin (STZ; 40 mg/kg). Diabetic, diabetic treated with insulin, and age-matched control animals were killed by overdoses of pentobarbital. The ventral prostatic lobe (VP) was dissected, weighed and processed for immunohistochemistry for AR, IGF-1 e IGF-1R; plasma T and DHT levels were also determined. Hyperglycemia at puberty reduced VP weight gain to about 50% and plasma T level to about 80% of the control levels. In contrast there were no changes in plasma DHT levels. Insulin replacement restored the VP weight gain, but not the plasma T levels, which remained 90% below the ones of controls. Immunohistochemistry showed that AR, IGF-1 and IGF-1R expression in the prostate epithelial cells did not change with hyperglycemia or insulin replacement. Thus, the AR expression in the prostate epithelial cells appears to be regulated by DHT, and to a minor extent it also controls glandular growth
