Elaboration of handbook about dietary fibers and bowel constipation

Objective: to elaborate a handbook with high-fiber foods to be used in the composition of the homogeneous liquid diet for patients in postoperative period to reduce or prevent the bowel constipation. Methods: the handbook highlights the importance of dietary fibers, classification, food sources, amount of use, interaction with other nutrients, directions for preparation, solubility, functions and problems caused by the excess ingestion. It also contains a list of food with fibers quantities present in 100 grams of each food. Such data were obtained from the Tabela Brasileira de Composição de Alimentos of Unicamp and Tabela Brasileira de Composição de Alimentos of University of São Paulo. The handbook was elaborated by students from Fundap Professional Improvement Program and distributed for free for all patients of the Hospital for Rehabilitation of Craniofacial Anomalies, in postoperative period, receiving homogeneous liquid diet. The handbook was also made available in the homepages www.centrinho.usp/manual and www.redeprofis.com.br for consultation and free copies. The handbook art and illustrations were made by a student of Marketing rom USC. Results: The use of fibers will be oriented in a preventive form for patients not showing bowel constipation and in a corrective form for those already constipated. Conclusions: Bowel constipation is a public health problem in Brazil, mainly among women, and it becomes worse when individuals are submitted to a homogeneous liquid diet in which the foods are liquefied and filtered and the residues (fibers) are rejected. In such case, the composition of this diet needs to be enriched with dietary fibers to prevent or correct the bowel constipation

Elaboração de manual sobre fibras alimentares e constipação intestinal

Objetivo: elaborar um manual com alimentos fonte de fibras para ser usado na composição da dieta líquida homogênea dos pacientes em pós-operatório no HRAC, de todas as idades, para reduzir ou prevenir a constipação intestinal. Métodos: o manual contém temática que esclarece sobre a importância das fibras alimentares, classificação, fontes, quantidades de uso, interação com outros nutrientes, forma de preparo, solubilidade, funções e problemas causados pelo excesso de ingestão. Consta também de uma lista de alimentos com quantidades de fibras presentes por 100gramas de cada alimento. Tais dados foram retirados da Tabela Brasileira de composição de Alimentos da UNICAMP e da Tabela Brasileira de Composição de Alimentos da USP. O manual foi elaborado pelas alunas do programa de Aprimoramento Profissional Fundap e será distribuído gratuitamente para todos os pacientes em pós-operatórios submetidos à dieta líquida homogênea. Além disto, o manual será disponibilizado nos sites www.centrinho.usp.br/manual e www.redeprofis.com.br. para consulta e cópias gratuitas. A arte e as ilustrações do manual foram feitas por aluno do Curso de Publicidade e Propaganda da USC. Resultados: O uso das fibras será orientado de forma preventiva para os pacientes que não apresentam constipação intestinal e de forma corretiva para os já constipados. Conclusões: A constipação intestinal é um problema de saúde pública no Brasil, principalmente entre as mulheres e tem seu quadro agravado quando estes indivíduos são submetidos a dietas líquidas e homogêneas, aonde os alimentos são liquidificados e coados e os resíduos (fibras) desprezados. Sendo assim, a composição desta dieta tem que ser enriquecida com fibras alimentares para prevenir ou corrigir a constipação intestinal

Communication calls produced by electrical stimulation of four structures in the guinea pig brain

One of the main central processes affecting the cortical representation of conspecific vocalizations is the collateral output from the extended motor system for call generation. Before starting to study this interaction we sought to compare the characteristics of calls produced by stimulating four different parts of the brain in guinea pigs (Cavia porcellus). By using anaesthetised animals we were able to reposition electrodes without distressing the animals. Trains of 100 electrical pulses were used to stimulate the midbrain periaqueductal grey (PAG), hypothalamus, amygdala, and anterior cingulate cortex (ACC). Each structure produced a similar range of calls, but in significantly different proportions. Two of the spontaneous calls (chirrup and purr) were never produced by electrical stimulation and although we identified versions of chutter, durr and tooth chatter, they differed significantly from our natural call templates. However, we were routinely able to elicit seven other identifiable calls. All seven calls were produced both during the 1.6 s period of stimulation and subsequently in a period which could last for more than a minute. A single stimulation site could produce four or five different calls, but the amygdala was much less likely to produce a scream, whistle or rising whistle than any of the other structures. These three high-frequency calls were more likely to be produced by females than males. There were also differences in the timing of the call production with the amygdala primarily producing calls during the electrical stimulation and the hypothalamus mainly producing calls after the electrical stimulation. For all four structures a significantly higher stimulation current was required in males than females. We conclude that all four structures can be stimulated to produce fictive vocalizations that should be useful in studying the relationship between the vocal motor system and cortical sensory representation

Quantitative Analysis of Placental Vasculature by Three-Dimensional Power Doppler Ultrasonography in Normal Pregnancies From 12 to 40 Weeks of Gestation

Evaluate the distribution and variation of placental vascular indices according to gestational age and placental volume. From March to November 2007, three-dimensional (3D)-power Doppler ultrasound was performed in 295 normal pregnancies from 12 to 40 weeks of gestation. Using the same preestablished settings for all patients, power Doppler was applied to the placenta and placental Volume was obtained by the rotational technique (VOCAL(TM)). The 3D-power histogram was used to determine the placental vascular indices: vascularization index (VI), flow index (FI) and vascularization-flow index (VFI). The placental vascular indices were then plotted against gestational age and placental volume. All placental vascular indices showed constant distribution throughout gestation. A tendency for a reduction in placental vascular indices with increased placental volume was observed, but was only statistically significant when placental FI was considered (p < 0.05). All placental vascular indices estimated by 3D-power Doppler ultrasonography presented constant distribution throughout gestation, despite the increase in placental volume according to gestational age.

Early fetal cystoscopy for first-trimester severe megacystis

Objectives To report the feasibility of early fetal cystoscopy for the prenatal diagnosis and therapy of severe first-trimester megacystis. Methods Between January 2008 and February 2010, early fetal cystoscopy at 16 weeks of gestation was offered to 15 patients whose fetuses presented with severe first-trimester megacystis. All infants were followed up for 6-12 months after birth. Autopsy was always performed whenever fetal or neonatal deaths occurred. Results Seven patients decided to undergo fetal therapy, and eight elected to continue with expectant observation. One fetus died before early fetal cystoscopy was performed. Therefore, six fetuses underwent early fetal cystoscopy. Urethral atresia was diagnosed in three fetuses during fetal cystoscopy and confirmed at autopsy following termination of pregnancy at 19-20 weeks in all cases. Posterior urethral valves were diagnosed and successfully fulgurated by laser during early cystoscopy in three fetuses, two of which survived with normal renal and bladder function after birth; the remaining fetus had a postnatal diagnosis of megacystis-microcolon intestinal hypoperistalsis syndrome and died neonatally. In the expectantly managed group, no survivals were observed, even among cases with `isolated` posterior urethral valves. Conclusions Percutaneous early fetal cystoscopy is feasible for prenatal diagnosis and therapy of severe megacystis. Copyright (C) 2011 ISUOG. Published by John Wiley & Sons, Ltd

Resistance exercise and glycemic control in women with gestational diabetes mellitus

OBJECTIVE: The objective of the study was to evaluate the effect of a resistance exercise program with an elastic band on insulin requirement and glycemic control in patients with gestational diabetes mellitus (GDM). STUDY DESIGN: Sixty-four patients with gestational diabetes mellitus were randomly assigned into 2 groups: an exercise group (EG; n = 32) and a control group not submitted to the exercise program (CG; n = 32). RESULTS: A significant reduction in the number of patients who required insulin was observed in the EG (7/32) compared with the CG group (18/32) (P = .005). The percentage of time spent within the proposed target glucose range (of at least 80% of weekly measurements below the limits preestablished for the disease) was significantly higher in EG compared with the CG group (EG = 0.63 +/- 0.30; CG = 0.41 +/- 0.31; P = .006). CONCLUSION: The resistance exercise program was effective in reducing the number of patients with GDM who required insulin and in improving capillary glycemic control in this population.CAPES Coordenação de Aperfeiçoamento de Pessoal de Nível Superio

Ductus venosus Doppler and postnatal outcomes in fetuses with absent or reversed end-diastolic flow in the umbilical arteries

Objective: To evaluate the relationship between ductus venosus Doppler findings on the day of delivery and postnatal outcomes in pregnancies with absent or reversed end-diastolic (ARED) flow in the umbilical arteries.Study design: Postnatal outcomes of 103 newborns of pregnancies with a diagnosis of ARED flow on Doppler velocimetry of the umbilical arteries were analyzed retrospectively between January 1997 and December 2004. Single pregnancies and fetuses without malformations were included. the cases were divided into two groups according to the flow during atrial contraction (a-wave) in the ductus venosus on the day of delivery: group A, 20 cases with absent or reversed flow in the ductus venosus and group B, 83 cases with positive flow. the results were analyzed statistically using the chi-square test, Fisher's exact test and the Mann-Whitney U test with the level of significance set at 5%.Results: All newborns were delivered by cesarean section. Gestational age was similar in the two groups (group A: 30 weeks and group B: 30.9 weeks, P = 0.23). Absent or reversed ductus venosus flow was associated with the following adverse postnatal outcomes: lower birthweight (P < 0.001), lower Apgar scores in the first (P = 0.001) and fifth minute (P = 0.001), a higher frequency of orotracheal intubation (P = 0.001) and pH at birth less than 7.20 (P < 0.001), pulmonary hemorrhage (P = 0.03), thrombocytopenia (P = 0.02), hypoglycemia (P = 0.01), intracranial hemorrhage (P = 0.02), and postnatal death (P = 0.007).Conclusion: the study of ductus venosus flow may provide additional information regarding the best time for interruption of pregnancies with ARED flow in the umbilical arteries characterized by extreme prematurity.
