Obesity and gestational weight gain: cesarean delivery and labor complications

OBJECTIVE: To assess the association between pre-gestational obesity and weight gain with cesarean delivery and labor complications. METHODS: A total of 4,486 women 20-28 weeks pregnant attending general prenatal care clinics of the national health system in Brazil from 1991 to 1995 were enrolled and followed up through birth. Body mass index categories based on prepregnancy weight and total weight gain were calculated. Associations between body mass index categories and labor complications were adjusted through logistic regression analysis. RESULTS: Obesity was present in 308 (6.9%) patients. Cesarean delivery was performed in 164 (53.2%) obese, 407 (43.1%) pre-obese, 1,045 (35.1%) normal weight and 64 (24.5%) underweight women. The relative risk for cesarean delivery in obese women was 1.8 (95% CI: 1.5-2.0) compared to normal weight women. Greater weight gain was particularly associated with cesarean among the obese (RR 4th vs 2nd weight gain quartile 2.2; 95% CI: 1.4-3.2). Increased weight at the beginning of pregnancy was associated with a significantly higher adjusted risk of meconium with vaginal delivery and perinatal death and infection in women submitted to cesarean section. Similarly, greater weight gain during pregnancy increased the risk for meconium and hemorrhage in women submitted to vaginal delivery and for prematurity with cesarean. CONCLUSIONS: Pre-gestational obesity and greater weight gain independently increase the risk of cesarean delivery, as well as of several adverse outcomes with vaginal delivery. These findings provide further evidence of the negative effects of prepregnancy obesity and greater gestational weight gain on pregnancy outcomes.

Determinantes precoces da glicemia casual em adultos da coorte de nascimentos de 1982, Pelotas, RS

OBJETIVO: Avaliar o efeito de variáveis socioeconômicas, peso ao nascer, duração da amamentação e mudança de renda sobre a glicemia ao acaso em jovens adultos. MÉTODOS: Estudo sobre coorte de nascidos em 1982, quando os 5.914 nascimentos hospitalares ocorridos na cidade de Pelotas foram identificados e as mães entrevistadas. As crianças, cujas famílias residiam na área urbana da cidade, foram acompanhadas diversas vezes. Em 2004-5, 4.927 indivíduos da coorte foram entrevistados e 3.730 tiveram sangue da polpa digital coletado para medida da glicemia casual. Foi avaliada a associação entre glicemia casual e cor da pele, renda familiar ao nascer, escolaridade materna, mudança de renda entre 1982 e 2004-5, peso ao nascer e duração da amamentação. RESULTADOS: A média da glicemia foi de 97,3±15,1mg/dL, sendo maior entre os homens. Nenhuma das variáveis estudadas esteve associada com a glicemia dos homens. Entre as mulheres, a escolaridade materna, a renda familiar aos 23 anos e o peso ao nascimento estiveram inversamente associados com a glicemia. Contudo, o efeito do peso ao nascer perdeu a significância estatística na análise multivariável. CONCLUSÕES: O peso ao nascer e a duração da amamentação não apresentaram efeito em longo prazo sobre a glicemia casual, apenas a escolaridade materna e a renda atual estiveram associados com a glicemia casual nas mulheres.

Social contextual factors contributing to child and adolescent labor: an ecological analysis

OBJECTIVE: To examine the relationship between social contextual factors and child and adolescent labor. METHODS: Population-based cohort study carried out with 2,512 families living in 23 subareas of a large urban city in Brazil from 2000 to 2002. A random one-stage cluster sampling was used to select families. Data were obtained through individual household interviews using questionnaires. The annual cumulative incidence of child and adolescent labor was estimated for each district. New child and adolescent labor cases were those who had their first job over the two-year follow-up. The annual cumulative incidence of child and adolescent labor was the response variable and predictors were contextual factors such as lack of social support, social deprivation, unstructured family, perceived violence, poor school quality, poor environment conditions, and poor public services. Pearson's correlation and multiple linear regression were used to assess the associations. RESULTS: There were selected 943 families corresponding to 1,326 non-working children and adolescents aged 8 to 17 years. Lack of social support, social deprivation, perceived violence were all positively and individually associated with the annual cumulative incidence of child and adolescent labor. In the multiple linear regression model, however, only lack of social support and perceived violence in the neighborhood were positively associated to child and adolescent labor. No effect was found for poor school quality, poor environment conditions, poor public services or unstructured family. CONCLUSIONS: Poverty reduction programs can reduce the contextual factors associated with child and adolescent labor. Violence reduction programs and strengthening social support at the community level may contribute to reduce CAL.

Effects of acupressure on progress of labor and cesarean section rate: randomized clinical trial

OBJECTIVE To analyze the effects of acupressure at the SP6 point on labor duration and cesarean section rates in parturients served in a public maternity hospital.METHODS This controlled, randomized, double-blind, pragmatic clinical trial involved 156 participants with gestational age ≥ 37 weeks, cervical dilation ≥ 4 cm, and ≥ 2 contractions in 10 min. The women were randomly divided into an acupressure, placebo, or control group at a university hospital in an inland city in the state of Sao Paulo, Brazil, in 2013. Acupressure was applied to the SP6 point during contractions for 20 min.RESULTS The average labor duration was significantly different between the SP6 acupressure group [221.5 min (SD = 162.4)] versus placebo [397.9 min (SD = 265.6)] and versus control [381.9 min (SD = 358.3)] (p = 0.0047); however, the groups were similar regarding the cesarean section rates (p = 0.2526) and Apgar scores in the first minute (p = 0.9542) and the fifth minute (p = 0.7218) of life of the neonate.CONCLUSIONS The SP6 acupressure point proved to be a complementary measure to induce labor and may shorten the labor duration without causing adverse effects to the mother or the newborn. However, it did not affect the cesarean section rate.

Adiaspiromicose pulmonar: achado casual em paciente falecido de febre amarela

À necropsia, microscopicamente, além das alterações hepáticas características da infecção, encontraram-se nos pulmões e linfonodos hilares, estruturas arredondadas, reconhecidas como adiaconídios de Emmonsia parva var. crescens.

Monitorização ambulatorial da pressão arterial e pressão casual em hiper-reatores ao esforço

FUNDAMENTO: O desenvolvimento de hipertensão arterial sustentada é, pelo menos, duas vezes maior em indivíduos hiper-reatores ao esforço. Poucos trabalhos têm avaliado os parâmetros da monitorização ambulatorial da pressão arterial de 24 horas (MAPA) nesses indivíduos. OBJETIVO: Avaliar a relação da pressão arterial (PA) casual com a resposta hiper-reativa ao esforço (RHR) e comparar os padrões da monitorização ambulatorial de pressão arterial (MAPA) de indivíduos hiper-reatores ao esforço a um grupo controle, visando detectar alterações precoces que permitam uma atuação preventiva com implicação prognóstica. MÉTODOS: A PA casual e os dados da MAPA de 26 indivíduos adultos, com idade média de 41,50±11,78 anos, normotensos em repouso, hiper-reatores ao teste ergométrico (TE), foram comparados aos de 16 adultos, com média de idade de 41,38±11,55 anos, também normotensos em repouso, com resposta normal de PA ao esforço. Como normotensão foram considerados valores de PA <140x90mmHg. Para o diagnóstico de hiper-reatividade foram aceitos valores de pressão arterial sistólica (PAS) >220mmHg e/ou incremento >15mmHg de pressão arterial diastólica (PAD) no TE, partindo-se de níveis de PA normais. RESULTADOS: A PAS (p=0,03) e PAD (p=0,002) casuais, a média da PAS (p=0,050) e as cargas pressóricas sistólicas na vigília (p=0,011) e nas 24 horas (p=0,017) à MAPA foram significativamente superiores nos hiper-reatores. CONCLUSÃO: A PA casual se correlacionou positivamente com a RHR. Os hiper-reatores apresentaram características peculiares na PA casual e MAPA, que, embora dentro da normalidade, se diferenciaram das observadas nos normorreatores.

Comparação e correlação entre automedida, medida casual e monitorização ambulatorial da pressão arterial

FUNDAMENTO: A medida casual da pressão arterial (PA) pelos profissionais de saúde está sujeita a uma grande variabilidade, sendo necessário buscar novos métodos que possam superar essa limitação. OBJETIVO: Comparar e avaliar a correlação entre os níveis de PA obtidos por meio da automedida da pressão arterial (AMPA) com a medida casual e com a monitorização ambulatorial da pressão arterial (MAPA). MÉTODOS: Avaliamos hipertensos que realizaram as três metodologias de medida da PA com intervalo menor que 30 dias; as médias das pressões foram utilizadas para comparação e correlação. Foram empregados os aparelhos: OMRON 705 CP (medida casual), OMRON HEM 714 (AMPA) e SPACELABS 9002 (MAPA). RESULTADOS: Foram avaliados 32 pacientes, 50,09% mulheres, idade média 59,7 (± 11,2) anos, média do IMC 26,04 (± 3,3) kg/m². Valores médios de pressão sistólica (PAS) e pressão diastólica (PAD) para a AMPA foram de 134 (± 15,71)mmHg e 79,32 (± 12,38) mmHg. Na medida casual as médias da PAS e PAD foram, respectivamente, 140,84 (± 16,15)mmHg e 85 (± 9,68) mmHg. Os valores médios da MAPA na vigília foram 130,47 (± 13,26) mmHg e 79,84 (± 9,82) mmHg para PAS e PAD, respectivamente. Na análise comparativa, a AMPA apresentou valores semelhantes aos da MAPA (p > 0,05) e diferentes da medida casual (p < 0,05). Na análise de correlação a AMPA foi superior à medida casual, considerando a MAPA como o padrão de referência nas medidas tensionais. CONCLUSÃO: A AMPA apresentou melhor comparação com a MAPA do que a medida casual e também se correlacionou melhor com a aquela, especialmente para a pressão diastólica, devendo ser considerada uma alternativa com baixo custo para o acompanhamento do paciente hipertenso.

A dialética da vida cotidiana de doentes com insuficiência renal crônica: entre o inevitável e o casual

Procurou-se compreender o cotidiano da vida de doentes com insuficiência renal crônica em hemodiálise sob a visão do referencial teórico-metodológico do materialismo histórico e dialético. As entrevistas realizadas com 18 doentes foram submetidas ao procedimento de análise de discurso, revelando temas da realidade social da vida cotidiana destes doentes. Estes temas foram, então, analisados frente às categorias: processo saúde-doença; possibilidade x realidade e necessidade x casualidade. Para estes doentes o tratamento hemodialítico é inevitável e o transplante é casual e, entre esta relação dialética está a enfermagem que precisa ampliar sua compreensão sobre a árdua, triste, difícil e monótona realidade e suas possibilidades de transformação.

Expansion of undergraduate courses in nursing: dilemmas and contradictions facing the labor market

We sought to analyze, from the perspective of professors and students, the reasons and consequences of the expansion of undergraduate courses in nursing, discussing the dilemmas and the contradictions confronting the labor market. It was a qualitative study with data obtained from focus groups, conducted in 18 undergraduate nursing courses in the state of Minas Gerais, during the period of February to October of 2011. The narratives were submitted to critical discourse analysis. The results indicated that the education of the nurse was permeated by insecurity as to the future integration into the labor market. The insecurity translates into dilemmas that referred to employability and the precariousness of the working conditions. In this context, employment in the family health strategy emerges as a mirage. One glimpses the need for a political agenda with the purpose of discussion about education, the labor market and the determinants of these processes.

HARVEST LABOR QUALITY AND PRODUCTIVITY:CASE STUDY OF CHERRY GROWING IN CHILE

In Chile, the cherry tree has been one of the fastest growing and most profitable crops in the last ten years. However, increasing production costs, the scarcity of hired labor, and unfavorable exchange rates have reduced the productivity and competitiveness of the Chilean fruit sector. The aim of this article is to evaluate the harvest labor quality in cherry growing in Chile through the use of productivity indicators. A harvest labor evaluation system (HLES) was designed and four indicators were measured: Average Weight of Harvested Box, Average Daily Production per Worker, Percent of Export Fruit, and Percent of Fruit Discarded. Significant differences werefound between the 2010/11 season (with the HLES implementation) and the previous seasons without HLES. The average worker yield, average weight of a filled box, and fruit quality improved, while the amount of discarded fruit decreased. Hired labor management in agriculture is crucial for improving the productivity of the fresh fruit export producers. The use of HLES and the adoption of new technologies could help to solve the competitiveness problem in the Chilean fruit sector.

Induction of labor with titrated oral misoprostol solution versus oxytocin in term pregnancy: randomized controlled trial

PURPOSE: To evaluate the effectiveness and the safety of orally administered misoprostol in comparison to intravenously infused oxytocin for labor induction in term pregnant women. METHODS: Between 2008 and 2010, a total of 285 term pregnant women whom were candidate for vaginal delivery were assessed for eligibility to enter the study. Twenty five patients were excluded for different reasons; and 260 included women were randomly assigned to one of the two groups according to the method of treatment, misoprostol or oxytocin. The misoprostol group received 25 µg every 2 hours for up to 24 hours for induction. The oxytocin group received an infusion of 10 IU which was gradually increased. The time from induction to delivery and induction to the beginning of the active phase and successful inductions within 12, 18, and 24 hours were recorded. The trial is registered at irct.ir, number IRCT2012061910068N1. RESULTS: Failure of induction, leading to caesarean section was around 38.3% in the oxytocin group and significantly higher than that of the misoprostol group (20.3%) (p<0.001). Despite the more prevalent failure in the oxytocin group, the mean time intervals from induction to active phase and labor of this group were both significantly less than the misoprostol group (10.1±6.1 and 13.2±7.7 versus 12.9±5.4 and 15.6±5.1 hours respectively, both p-values were <0.05). Maternal and fetal complications were comparable between groups except gastrointestinal symptoms which were encountered more frequently in the misoprostol (10.9 versus 3.9%, p=0.03). CONCLUSIONS: Misoprostol is a safe and effective drug with low complications for the induction of labor. Failure is seen less with misoprostol and caesarean sections are less frequently indicated as compared to oxytocin.

Estimation of Fetal Weight during Labor: Still a Challenge

Objective To evaluate the accuracy of fetal weight prediction by ultrasonography labor employing a formula including the linear measurements of femur length (FL) and mid-thigh soft-tissue thickness (STT). Methods We conducted a prospective study involving singleton uncomplicated term pregnancies within 48 hours of delivery. Only pregnancies with a cephalic fetus admitted in the labor ward for elective cesarean section, induction of labor or spontaneous labor were included. We excluded all non-Caucasian women, the ones previously diagnosed with gestational diabetes and the ones with evidence of ruptured membranes. Fetal weight estimates were calculated using a previously proposed formula [estimated fetal weight = [1] 1687.47 + (54.1 x FL) + (76.68 x STT). The relationship between actual birth weight and estimated fetal weight was analyzed using Pearson's correlation. The formula's performance was assessed by calculating the signed and absolute errors. Mean weight difference and signed percentage error were calculated for birth weight divided into three subgroups: < 3000 g; 3000-4000g; and > 4000 g. Results We included for analysis 145 cases and found a significant, yet low, linear relationship between birth weight and estimated fetal weight (p < 0.001; R2 = 0.197) with an absolute mean error of 10.6%. The lowest mean percentage error (0.3%) corresponded to the subgroup with birth weight between 3000 g and 4000 g. Conclusions This study demonstrates a poor correlation between actual birth weight and the estimated fetal weight using a formula based on femur length and mid-thigh soft-tissue thickness, both linear parameters. Although avoidance of circumferential ultrasound measurements might prove to be beneficial, it is still yet to be found a fetal estimation formula that can be both accurate and simple to perform.

Extrato etanólico de Senna alata no controle de Myrothecium roridum, agente casual do cancro-de-mirotécio

O fungo M. roridum é o causador da doença cancro-de-mirotécio em meloeiro e vem provocando grandes perdas na produção dessa olerícola. É uma doença de difícil controle, em razão de seu agente ser habitante do solo. Devido à procura de formas alternativas de controle, o objetivo deste trabalho foi avaliar a atividade dos extratos etanólicos de partes de S. alata sobre M. roridum. O delineamento experimental foi inteiramente casualizado, distribuído em esquema fatorial 4 x 6 + 1, sendo o primeiro fator partes da planta (caule, inflorescência, raiz e vagem) e o segundo, seis concentrações (0,25; 0,50; 50; 75; 250; e 500 µg mL-1) mais a testemunha, com quatro repetições por tratamento. As variáveis avaliadas foram: taxa de crescimento micelial (TCM), inibição do crescimento micelial (ICM) e área abaixo da curva do crescimento micelial (AACCM). Todos os extratos de partes vegetais de S. alata foram eficientes em inibir o crescimento micelial de M. roridum. O extrato etanólico da vagem foi o que melhor inibiu o crescimento de M. roridum, na concentração de 500 µg mL-1 , seguido do extrato da raiz e do caule.
