Pregnancy in women undergoing hemodialysis: case series in a Southeast Brazilian reference center / Gestação em mulheres em tratamento hemodialítico: série de casos em um centro de referência do Sudeste do Brasil

PURPOSE: To describe maternal and neonatal outcomes in pregnant women undergoing hemodialysis in a referral center in Brazilian Southeast side. METHODS: Retrospective and descriptive study, with chart review of all pregnancies undergoing hemodialysis that were followed-up at an outpatient clinic of high- risk prenatal care in Southeast Brazil. RESULTS: Among the 16 women identified, 2 were excluded due to follow-up loss. In 14 women described, hypertension was the most frequent cause of chronic renal failure (half of cases). The majority (71.4%) had performed hemodialysis treatment for more than one year and all of them underwent 5 to 6 hemodialysis sessions per week. Eleven participants had chronic hypertension, 1 of which was also diabetic, and 6 of them were smokers. Regarding pregnancy complications, 1 of the hypertensive women developed malignant hypertension (with fetal growth restriction and preterm delivery at 29 weeks), 2 had acute pulmonary edema and 2 had abruption placenta. The mode of delivery was cesarean section in 9 women (64.3%). All neonates had Apgar score at five minutes above 7. CONCLUSIONS: To improve perinatal and maternal outcomes of women undergoing hemodialysis, it is important to ensure multidisciplinary approach in referral center, strict control of serum urea, hemoglobin and maternal blood pressure, as well as close monitoring of fetal well-being and maternal morbidities. Another important strategy is suitable guidance for contraception in these women. .

OBJETIVOS: Descrever os resultados maternos e neonatais de mulheres grávidas que estavam em tratamento de hemodiálise em um centro de referência no Sudeste brasileiro. MÉTODOS: Estudo retrospectivo e descritivo, com revisão de prontuários de todas as gestações em hemodiálise, acompanhadas no pré-natal especializado da região Sudeste do Brasil. RESULTADOS: Entre as 16 mulheres identificadas, 2 foram excluídas devido à perda de seguimento. Das 14 descritas, a hipertensão foi a causa mais frequente de insuficiência renal crônica (50% dos casos). A maioria (71,4%) realizava tratamento de hemodiálise há mais de um ano e todas elas foram submetidas a 5 ou 6 sessões por semana. Onze mulheres tinham hipertensão crônica, 1 das quais também era diabética, e 6 eram fumantes. Em relação às complicações da gravidez, 1 das mulheres hipertensas desenvolveu hipertensão maligna (com restrição de crescimento fetal e parto prematuro com 29 semanas), 2 tiveram edema pulmonar agudo e 2 apresentaram descolamento prematuro de placenta. O tipo de parto foi cesariana em 9 mulheres (64,3%). Todos os recém-nascidos tiveram Apgar aos cinco minutos maior que 7. CONCLUSÕES: Para melhorar os resultados perinatais e maternos de mulheres em hemodiálise, é importante ter uma abordagem multidisciplinar em centro de referência, um controle rigoroso da uremia, hemoglobina e pressão arterial materna, bem como acompanhar de perto o bem-estar fetal e a morbidade materna. Outra estratégia importante é a orientação adequada para contracepção nessas mulheres. .

Predictive factors of alcohol and tobacco use in adolescents / Fatores preditivos do uso de álcool e tabaco em adolescentes / Factores predictivos del uso de alcohol y tabaco en los adolescentes

OBJECTIVES: to analyze the effect of self-esteem, assertiveness, self-efficacy and resiliency on alcohol and tobacco consumption in adolescents. METHOD: a descriptive and correlational study was undertaken with 575 adolescents in 2010. The Self-Esteem Scale, the Situational Confidence Scale, the Assertiveness Questionnaire and the Resiliency Scale were used. RESULTS: the adjustment of the logistic regression model, considering age, sex, self-esteem, assertiveness, self-efficacy and resiliency, demonstrates significance in the consumption of alcohol and tobacco. Age, resiliency and assertiveness predict alcohol consumption in the lifetime and assertiveness predicts alcohol consumption in the last year. Similarly, age and sex predict tobacco consumption in the lifetime and age in the last year. CONCLUSION: this study can offer important information to plan nursing interventions involving adolescent alcohol and tobacco users. .

OBJETIVOS: analisar o efeito da autoestima, assertividade, autoeficácia e resiliência sobre o consumo de álcool e tabaco em adolescentes. MÉTODO: estudo descritivo correlacional com 575 adolescentes, realizado no ano 2010. Foram utilizadas a Escala de Autoestima, o Questionário de Confiança Situacional, o Questionário de Assertividade e a Escala de Resiliência. RESULTADOS: o ajuste do modelo de regressão logística, considerando a idade, sexo, autoestima, assertividade, autoeficácia e resiliência foi significante em relação ao consumo de álcool e tabaco. A idade, resiliência e assertividade foram preditores do consumo de álcool em algum momento na vida e a idade e a assertividade foram preditores no último ano. Para o consumo de tabaco, a idade e o sexo foram preditores em algum momento na vida e a idade no último ano. CONCLUSÃO: este estudo pode proporcionar informações importantes para o planejamento de intervenções de enfermagem em adolescentes usuários de álcool e tabaco .

A socialização da medicina na era do adhemarismo / The socialization of medicine in the era of São Paulo Governor Adhemar de Barros

A análise observa as conexões entre o processo de profissionalização dos médicos paulistas e políticas de saúde do governo estadual de Adhemar de Barros em São Paulo (1947-1951), em meio a amplas mudanças na área de saúde denominadas pelos médicos paulistas “socialização da medicina”. Reconhecemos aspectos ambivalentes para o profissionalismo médico diante desse governo populista, como: a luta médica pela equiparação ante os advogados servidores públicos estaduais; a criação de uma secretaria de saúde estadual; e certos elos contraditórios entre a área de saúde adhemarista e a ideologia e a organização profissionais da medicina paulista. Nesse particular, o artigo aprofunda a análise de manifestações ideológicas de importantes lideranças médicas paulistas.

The article analyzes how the process of the professionalization of physicians in São Paulo related to healthcare policy under the administration of São Paulo governor Adhemar de Barros (1947-1951) during a period of broad change in the realm of health known by São Paulo physicians as the “socialization of medicine.” Medical professionalism confronted certain ambivalences under this populist administration, including doctors’ struggle to achieve pay equal to that of state public attorneys; the establishment of a state health department; and some contradictory ties between the area of health under Adhemar and the professional ideology and organization of medicine in São Paulo. The article undertakes a more in-depth analysis of the ideological manifestations of important leaders in the state’s medical community.

Association between embB mutations and ethambutol resistance in Mycobacterium tuberculosis isolates from Cuba and the Dominican Republic: reproducible patterns and problems / Association between embB mutations and ethambutol resistance in Mycobacterium tuberculosis isolates from Cuba and the Dominican Republic: reproducible patterns and problems.

The relation of ethambutol resistance to embB mutations remains unclear, and there are no reports on ethambutol resistance from the caribbean. We examined the sequence of embB in 57 distinct Multi-Drug Resistant (MDR) and non-MDR strains of Mycobacterium tuberculosis, mostly from Cuba and the Dominican Republic. embB306 codon mutations were found exclusively in MDR-TB, but in both ethambutol sensitive and resistant strains. Valine substitutions predominated in ethambutol resistant strains, while isoleucine replacements were more common in sensitive strains. Three ethambutol resistant MDR strains without embB306 substitutions had replacements in embB406 or embB497, but these were also found in ethambutol sensitive MDR strains. The results confirm previous findings that amino acid substitutions in EmbB306, EmbB406 and EmbB497 are found only in MDR-TB strains but in both phenotypically resistant and sensitive strains. One ethambutol resistant non-MDR strain did not have any embB mutation suggesting that other undefined mutations can also confer ethambutol resistance.

Tiempo mínimo para detectar calidad proteica usando indicadores del catabolismo proteico en pollos / Minimal time for detecting protein quality using indicators of protein catabolism in chickens

Previous studies shown that in chickens the hepatic activities of the purine enzymes Xanthine Dehydrogenase and Nucleoside Phosphorylase and the uric acid excretion can predict the quality of the protein consumed in a very short time. In these studies even though the experimental time was short, the time used for the conditioning of the chickens was long and included five days with six chickens per cage and then five to six days for progressively changing the chickens to individual cages in order to avoid the stress associated with the isolation of the animals. Thus the purpose of this study was to determine the minimal time required to detect differences in these parameters after feeding a soy-met and a gelatin diet and eliminating completely the time required for the isolation of the chickens. Thus, 76 one day old Warren male chickens were placed in groups of six on a soy-met powdered diet during five days and on day six all the chicken were placed in individual cages and one halve was offered the same diet while the rest received a gelatin diet. Then on day 1, 2, 3, 5, 7, 10 and 15 after the diet change five chickens on each diet were sacrificed and the activity of the liver purine enzymes as well as the uric acid excreted were determined.(ABSTRACT TRUNCATED AT 250 WORDS)
