In comparison to the impact of surgery on cytokine and complement levels, the transfusion of autologous buffy coat is not relevant.

Objective: To determine the true platelet count in blood salvaged and processed for autotransfusion. Design: Prospective, randomized study. Setting: Department of anesthesiology and orthopedic clinic of a university hospital. Patients: 60 patients who were scheduled for elective hip surgery and included in routine intra- and postoperative blood salvage and autotransfusion programs. Interventions: Patients were randomly divided into 2 groups. In group I (n = 30) autotransfusion was performed using the Continuous Autotransfusion System^® (Fresenius), in group II (n = 30) the Cell Saver 5^® (Haemonetics) was used. In both groups samples were taken from the collection reservoir and the washed red cells. Platelet counts were performed with an automated cell analyzer and by flow-cytometric analysis using the monoclonal antibody CD42a. Results: The platelet counts obtained by the automated analyzer were 5 to 21 times higher than those obtained by flow-cytometric analysis. This appears to be due to the contamination of the samples with cell debris of about the same size as platelets. The platelet counts stated in literature should be reconsidered. Conclusions: Automatic cell-counting devices are inadequate to determine the platelet count of blood salvaged and processed for autotransfusion.

II Modelo experimental de reconstrução em falha mandibular em coelhos INTRODUÇÃOAs falhas ósseas da mandíbula, tanto em humanos, quanto em animais, podem ser causadas por remoção de neoplasias, trauma e infecções ou constituir deformidade congênita (BRANDÃO & ARAÚJO, 1989, VERSTRAETE & OSOFSKY, 2005. As técnicas de reconstrução mandibular têm representado um desafio para os cirurgiões bucomaxilofaciais e ortopedistas (LI & LI, 2005). ParaRecebido para publicação 18.08

Resumo Objetivou-se avaliar o impacto do consumo de sucos antes dos 6 meses de idade no Índice de Massa Corporal para Idade (IMC/I) e no consumo alimentar em pré-escolares. Estudo longitudinal com amostra composta por mães e seus filhos (n=103) entre 6 meses e 3 a 6 anos. Peso e estatura foram aferidos e convertidos para o escore z de IMC/I. Para avaliar o consumo alimentar, foi utilizado o Questionário de Frequência Alimentar Infantil. Testes de Qui-Quadrado e t de Student foram utilizados para comparação entre os grupos. Não houve diferença nos parâmetros antropométricos entre pré-escolares que receberam ou não suco antes dos seis meses. Aquelas que tiveram introdução de suco mais precoce (≤150 dias de vida) apresentaram consumo mais frequente (≥1x/dia) de suco artificial (63,8% versus 35,7%; p=0,028) e biscoito recheado (21,3% versus 14,3%; p=0,001) na idade pré-escolar. Crianças que receberam suco do tipo artificial antes dos 6 meses tiveram maior prevalência de consumo de refrigerante entre 1 e 4x/semana (69,2% versus 27,4%; p=0,014) e menor prevalência de consumo de achocolatado pelo menos 1x/dia (38,5% versus 69,4%; p=0,027). Sendo assim, crianças com introdução precoce de suco apresentaram maior consumo de alimentos doces e bebidas açucaradas em fase pré-escolar.

The aim of this study was to evaluate the impact of fruit juice consumption before 6 months of age on Body Mass Index-for-age (BMI-for-age) and food consumption in preschoolers. We conducted a longitudinal study with mothers and their children (n=103) at 6 months and 3-6 years. Weight and height were measured and converted into BMI-for-age z-scores. Food consumption was analyzed using the Food Frequency Questionnaire for Children. Groups were compared using the chi-squared and Student’s t-tests. No differences in anthropometric measurements were found at preschool age between children who had been given fruit juice before 6 months and those who had not. Consumption of artificial juice (≥once/day) and sandwich cookies at preschool age was higher in children with early introduction of fruit juice (≤150 days of life) (63.8% versus 35.7%; p=0.028 and 21.3% versus 14.3%; p=0.001, respectively). The prevalence of the consumption of soda (1 to 4 times/week) and chocolate milk (at least once/day) was higher in children who had been given artificial juice before 6 months (69.2% versus 27.4%; p=0.014 and 38.5% versus 69.4%; p=0.027, respectively). It can be concluded that the consumption of sweet foods and sugary beverages was higher in children with early introduction of fruit juice.

Objectives: to evaluate the association between dietary intake during pregnancy and different gestational clinical conditions (hypertensive, diabetics, smokers, having intrauterine growth restriction and a control group) and associated factors. Methods: cross-sectional study nested in a cohort study from 2011 to 2016 that occurred in three hospitals in Porto Alegre (Brazil). Sociodemographic conditions and prenatal were investigated and maternal feeding practices were analyzed by the Food Frequency Questionnaire. To calculate the caloric percentage from food groups, food items were categorized into:unprocessed or minimally processed, processed and ultra-processed foods. The Kruskal-Wallis test with Dunn's post-hoc compared food consumption between the groups and the Poisson regression evaluated the association between the variables. Results: there was no statistical difference in food intake among 303 mothers of different gestational clinical conditions, but diabetic pregnant women had lower caloric contribution value of ultra-processed foods. In addition, pregnant women from all groups showed adequate consumption in relation to the percentage of caloric contribution of macronutrients in the total energy value. Conclusions: there was no difference in energy consumption according to different gestational clinical conditions.In diabetic, smokers and hypertensive pregnant women, associations between total energy intake and different sociodemographic factors were observed between the groups.

BACKGROUND The aim of the current study was to assess the influence of maternal weight gain in different clinical gestational conditions on the child's weight at pre-school age. METHODS longitudinal observational study of a prospective and controlled multiple cohort of 372 mother-child pairs from 2011 to 2016 in three hospitals in Porto Alegre (Brazil). Socio-demographic, prenatal and perinatal data were analyzed. Gestational weight gain (GWG) was categorized as "insufficient", "adequate" and "excessive". The Generalized Estimation Equations (GEE) model was used to assess changes in the Z score of the child's body mass index from birth to preschool age according to the GWG and gestational group. RESULTS A triple interaction effect was observed involving the gestational group, weight gain and time (p = 0.020) through an adjusted model. Maternal weight gain above the recommended is associated with a significant increase in the child's Z-BMI score over time, except for children from pregnant smokers. Children from diabetic (DM), hypertensive mothers, and the control group who had a weight gain above that recommended during pregnancy changed their nutritional status from eutrophic to overweight, becoming obese in the DM and hypertension groups and overweight in control. CONCLUSIONS Monitoring of the GWG, especially in the presence of hypertensive diseases and DM, should be effective to prevent children from developing overweight or obesity in preschool age with an important impact on health conditions in the future.
