Effect of ambulatory versus hospital treatment for gestational diabetes or hyperglycemia on infant mortality rates: a systematic review

CONTEXTO E OBJETIVO:Gestações complicadas pelo diabetes estão associadas com aumento das complicações neonatais e maternas. A complicação mais grave materna é o risco de desenvolver diabetes tipo 2 após 10-12 anos do parto. Para o controle rigoroso da glicose no sangue, as mulheres grávidas são tratadas de forma ambulatorial ou com internações hospitalares. O objetivo deste estudo é avaliar a efetividade do tratamento ambulatorial versus hospitalização em gestações complicadas por diabetes ou hiperglicemia.TIPO DE ESTUDO E LOCAL:Revisão sistemática conduzida em hospital universitário público.MÉTODOS:Uma revisão sistemática da literatura foi realizada e as principais bases de dados eletrônicas foram pesquisadas. A data da pesquisa mais recente foi 4 de setembro de 2011. Dois autores selecionaram independentemente os ensaios clínicos relevantes, avaliaram a qualidade metodológica e extraíram os dados.RESULTADOS:Apenas três estudos foram selecionados, com tamanho de amostra pequeno. Não houve diferença estatisticamente significativa entre o tratamento ambulatorial versus hospitalização em relação à mortalidade em nenhuma das subcategorias analisadas: mortes perinatais e neonatais, (risco relativo [RR] 0,65; 95% de intervalo de confiança [IC] 0,11-3,84, P = 0,63); morte neonatal (RR 0,29, IC 95% 0,01-6,07, P = 0,43), e óbitos infantis (RR 0,29, IC 95% 0,01-6,07, P = 0,43).CONCLUSÕES:Com base em estudos com risco de viés alto ou moderado, esta revisão demonstrou que não há diferença estatisticamente significante entre o tratamento ambulatorial comparado com o hospitalar na redução das taxas de mortalidade em gestações complicadas por diabetes ou hiperglicemia. Esta revisão sistemática também sugere a necessidade de mais ensaios clínicos randomizados sobre o assunto.

Nutrição da gestante portadora de anemia falciforme, complicações maternas e resultados perinatais

O prognóstico da gestação é influenciado pelo estado nutricional materno. Sabe-se que, desde a infância, as pessoas portadoras da doença falciforme apresentam crescimento deficiente. Pouco se conhece sobre a evolução do estado nutricional materno na anemia falciforme. O objetivo foi analisar o estado nutricional de gestantes portadoras de anemia falciforme, avaliando o ganho de peso, o consumo dietético materno e os resultados adversos maternos e perinatais. Métodos: Foram avaliadas 26 gestantes portadoras de anemia falciforme SS e 23 SC, a partir do início do pré-natal especializado até o puerpério. Como grupo controle foram utilizadas 63 gestantes, sem comorbidades. O estado nutricional das gestantes foi avaliado de acordo com índice de massa corporal, pré-gestacional e ao final da gravidez, bem como analisado o ganho de peso materno. O consumo dietético foi analisado utilizando-se questionário de frequência alimentar, em cada trimestre, caracterizando-se o valor energético total e a ingestão de macronutrientes e micronutrientes. As complicações maternas e perinatais foram investigadas. O nível de significância foi 0,05 (alfa=5%). Resultados: O IMC pré-gestacional foi significativamente menor no grupo SS (mediana 20,3 kg/m2) quando comparado com os grupos SC (22,7 kg/m2, p < 0,05) e controle (23,2 kg/m2, p < 0,05). O baixo peso pré-gestacional (IMC < 18,5 kg/m2) foi significativamente mais frequente no grupo SS (15,4%) quando comparado aos grupos SC (4,4%) e controle (1,6%, p=0,009). Ao final da gestação, o grupo SS apresentou menor IMC (mediana 23,1 kg/m2) quando comparado com o grupo SC (26,1 kg/m2, p < 0,05) e controle (28,5 kg/m2, p < 0,05). O ganho ponderal na gestação foi menor no grupo SS (mediana 8,0 kg) quando comparado com o grupo SC (11,9 kg, p < 0,05) e Controle (13,7 kg, p < 0,05). Na análise do consumo dietético no 2º trimestre, constatou-se que os grupos SS e SC apresentaram menor consumo de proteínas (medianas, 73 g/d e 69 g/d) quando comparados aos controles (96 g/d, p < 0,05); e o consumo de cálcio foi menor no grupo SS comparado ao controle (mediana, 410 vs. 748 g/d, p<0,05). No 3º trimestre, houve menor consumo de proteínas pelo grupo SS quando comparado com os controles (mediana, 68 g/d vs. 93 g/d, p < 0,05); o consumo de vitamina A foi menor no grupo SS quando comparado aos controles (mediana, 447 vs. 940 mcg/d, p < 0,05); o consumo de vitamina E foi menor no grupo SS (mediana, 6 mg/d) quando comparado aos grupos SC (10 mg/d) e controle (7 mg/d, p < 0,05). As complicações maternas mais frequentes foram: crise álgica, 58% no grupo SS e 44% no SC (p=NS); infecção urinária, 31% no SS e 17% no SC (p=NS); e infecção pulmonar, 35% no SS e 9% no SC (p=NS). Houve diferença significativa no diagnóstico de sofrimento fetal: SS (36%), SC (14%) e controle (13%, p=0,032). Resultados perinatais adversos foram mais frequentes nos grupos SS e SC quando comparados aos controles. Conclusões: O estado nutricional das gestantes portadoras de doença falciforme SS caracterizou-se pela desnutrição materna, com baixo ganho ponderal na gestação. O consumo dietético de macronutrientes demonstrou ingestão inadequada de proteínas nos 2º e 3º trimestres. As complicações maternas e resultados perinatais adversos foram eventos frequentes nas gestantes portadoras de doença falciforme

The prevalence of chronic diabetic complications and metabolic syndrome is not associated with maternal type 2 diabetes

The maternal history of type 2 diabetes mellitus (DM) has been reported more frequently in patients with type 2 DM than paternal history. The aim of the present study was to determine if there was an association between maternal history of DM and the presence of chronic complications or metabolic syndrome (MetS) in patients with type 2 DM. A cross-sectional study was conducted with 1455 patients with type 2 DM. All outpatients with type 2 diabetes attending the endocrine clinics who fulfilled the eligibility criteria were included. Familial history of DM was determined with a questionnaire. Diabetic complications were assessed using standard procedures. The definition of MetS used was that of the World Health Organization and the National Cholesterol Education Program's Adult Treatment Panel III report criteria. Maternal history of DM was present in 469 (32.3%), absent in 713 (49.1%) and unknown in 273 patients (18.7%). Paternal history of DM was positive in 255 (17.6%), negative in 927 (63.8%) and unknown in 235 patients (16.1%). The frequency of microvascular chronic complications in patients with and without a positive maternal history of DM was similar: diabetic nephropathy (51.5 vs 52.5%), diabetic retinopathy (46.0 vs 41.7%), and diabetic sensory neuropathy (31.0 vs 37.1%). The prevalence of macrovascular chronic complications and MetS was also similar. Patients with type 2 DM were more likely to have a maternal than a paternal history of DM, although maternal history of DM was not associated with an increased prevalence of chronic complications or MetS.

Maternal obesity in high-risk pregnancies and postpartum infectious complications

Objective: To analyze the association between maternal obesity and postnatal infectious complications in high-risk pregnancies. Methods: Prospective study from August 2009 through August 2010 with the following inclusion criteria: women up to the 5th postpartum day; age L 18 years; high-risk pregnancy; singleton pregnancy with live fetus at labor onset; delivery at the institution; maternal weight measured on day of delivery. The nutritional status in late pregnancy was assessed by the body mass index (BMI), with the application of the Atalah et al. curve. Patients were graded as underweight, adequate weight, overweight, or obese. Postpartum complications investigated during the hospital stay and 30 days post-discharge were: surgical wound infection and/or secretion, urinary infection, postpartum infection, fever, hospitalization, antibiotic use, and composite morbidity (at least one of the complications mentioned). Results: 374 puerperal women were included, graded according to the final BMI as: underweight (n = 54, 14.4%); adequate weight (n = 126, 33.7%); overweight (n = 105, 28.1%); and obese (n = 89, 23.8%). Maternal obesity was shown to have a significant association with the following postpartum complications: surgical wound infection (16.7%, p = 0.042), urinary infection (9.0%, p = 0.004), antibiotic use (12.3%, p < 0.001), and composite morbidity (25.6%, p = 0.016). By applying the logistic regression model, obesity in late pregnancy was found to be an independent variable regardless of the composite morbidity predicted (OR: 2.09; 95% CI: 1.15-3.80, p = 0.015). Conclusion: Maternal obesity during late pregnancy in high-risk patients is independently associated with postpartum infectious complications, which demonstrates the need for a closer follow-up of maternal weight gain in these pregnancies.

Delays In Receiving Obstetric Care And Poor Maternal Outcomes: Results From A National Multicentre Cross-sectional Study.

The vast majority of maternal deaths in low-and middle-income countries are preventable. Delay in obtaining access to appropriate health care is a fairly common problem which can be improved. The objective of this study was to explore the association between delay in providing obstetric health care and severe maternal morbidity/death. This was a multicentre cross-sectional study, involving 27 referral obstetric facilities in all Brazilian regions between 2009 and 2010. All women admitted to the hospital with a pregnancy-related cause were screened, searching for potentially life-threatening conditions (PLTC), maternal death (MD) and maternal near-miss (MNM) cases, according to the WHO criteria. Data on delays were collected by medical chart review and interview with the medical staff. The prevalence of the three different types of delays was estimated according to the level of care and outcome of the complication. For factors associated with any delay, the PR and 95%CI controlled for cluster design were estimated. A total of 82,144 live births were screened, with 9,555 PLTC, MNM or MD cases prospectively identified. Overall, any type of delay was observed in 53.8% of cases; delay related to user factors was observed in 10.2%, 34.6% of delays were related to health service accessibility and 25.7% were related to quality of medical care. The occurrence of any delay was associated with increasing severity of maternal outcome: 52% in PLTC, 68.4% in MNM and 84.1% in MD. Although this was not a population-based study and the results could not be generalized, there was a very clear and significant association between frequency of delay and severity of outcome, suggesting that timely and proper management are related to survival.

Contribution Of Antepartum And Intrapartum Hemorrhage To The Burden Of Maternal Near Miss And Death In A National Surveillance Study.

To evaluate the occurrence of severe obstetric complications associated with antepartum and intrapartum hemorrhage among women from the Brazilian Network for Surveillance of Severe Maternal Morbidity. Multicenter cross-sectional study. Twenty-seven obstetric referral units in Brazil between July 2009 and June 2010. A total of 9555 women categorized as having obstetric complications. The occurrence of potentially life-threatening conditions, maternal near miss and maternal deaths associated with antepartum and intrapartum hemorrhage was evaluated. Sociodemographic and obstetric characteristics and the use of criteria for management of severe bleeding were also assessed in these women. The prevalence ratios with their respective 95% confidence intervals adjusted for the cluster effect of the design, and multiple logistic regression analysis were performed to identify factors independently associated with the occurrence of severe maternal outcome. Antepartum and intrapartum hemorrhage occurred in only 8% (767) of women experiencing any type of obstetric complication. However, it was responsible for 18.2% (140) of maternal near miss and 10% (14) of maternal death cases. On multivariate analysis, maternal age and previous cesarean section were shown to be independently associated with an increased risk of severe maternal outcome (near miss or death). Severe maternal outcome due to antepartum and intrapartum hemorrhage was highly prevalent among Brazilian women. Certain risk factors, maternal age and previous cesarean delivery in particular, were associated with the occurrence of bleeding.

Maternal smoking during pregnancy: Impact on otoacoustic emissions in neonates

Objectives: To determine the effect of maternal smoking during pregnancy on transient evoked otoacoustic emissions levels in neonates. Methods: This was a cross-sectional study investigating neonates in the maternity ward of a university hospital in the city of Sao Paulo, Brazil. A total of 418 term neonates without prenatal or perinatal complications were evaluated. The neonates were divided into two groups: a study group, which comprised 98 neonates born to mothers who had smoked during pregnancy; and a control group, which comprised 320 neonates born to mothers who had not. In order to compare the two ears and the two groups in terms of the mean overall response and the mean transient evoked otoacoustic emissions in response to acoustic stimuli delivered at different frequencies, we used analysis of variance with repeated measures. Results: The mean overall response and the mean frequency-specific response levels were lower in the neonates in the study group (p < 0.001). The mean difference between the groups was 2.47 dB sound pressure level (95% confidence interval: 1.47-3.48). Conclusions: Maternal smoking during pregnancy had a negative effect on cochlear function, as determined by otoacoustic emissions testing. Therefore, pregnant women should be warned of this additional hazard of smoking. It is important that smoking control be viewed as a public health priority and that strategies for treating tobacco dependence be devised. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

Risk Prediction of Cardiovascular Complications in Pregnant Women With Heart Disease

Abstract Background: Heart disease in pregnancy is the leading cause of non- obstetric maternal death. Few Brazilian studies have assessed the impact of heart disease during pregnancy. Objective: To determine the risk factors associated with cardiovascular and neonatal complications. Methods: We evaluated 132 pregnant women with heart disease at a High-Risk Pregnancy outpatient clinic, from January 2005 to July 2010. Variables that could influence the maternal-fetal outcome were selected: age, parity, smoking, etiology and severity of the disease, previous cardiac complications, cyanosis, New York Heart Association (NYHA) functional class > II, left ventricular dysfunction/obstruction, arrhythmia, drug treatment change, time of prenatal care beginning and number of prenatal visits. The maternal-fetal risk index, Cardiac Disease in Pregnancy (CARPREG), was retrospectively calculated at the beginning of prenatal care, and patients were stratified in its three risk categories. Results: Rheumatic heart disease was the most prevalent (62.12%). The most frequent complications were heart failure (11.36%) and arrhythmias (6.82%). Factors associated with cardiovascular complications on multivariate analysis were: drug treatment change (p = 0.009), previous cardiac complications (p = 0.013) and NYHA class III on the first prenatal visit (p = 0.041). The cardiovascular complication rates were 15.22% in CARPREG 0, 16.42% in CARPREG 1, and 42.11% in CARPREG > 1, differing from those estimated by the original index: 5%, 27% and 75%, respectively. This sample had 26.36% of prematurity. Conclusion: The cardiovascular complication risk factors in this population were drug treatment change, previous cardiac complications and NYHA class III at the beginning of prenatal care. The CARPREG index used in this sample composed mainly of patients with rheumatic heart disease overestimated the number of events in pregnant women classified as CARPREG 1 and > 1, and underestimated it in low-risk patients (CARPREG 0).

Early vitamin K deficiency bleeding after maternal phenobarbital intake: management of massive intracranial haemorrhage by minimal surgical intervention.

Vitamin K deficiency bleeding within the first 24 h of life is caused in most cases by maternal drug intake (e.g. coumarins, anticonvulsants, tuberculostatics) during pregnancy. Haemorrhage is often life-threatening and usually not prevented by vitamin K prophylaxis at birth. We report a case of severe intracranial bleeding at birth secondary to phenobarbital-induced vitamin K deficiency and traumatic delivery. Burr hole trepanations of the skull were performed and the subdural haematoma was evacuated. Despite the severe prognosis, the infant showed an unexpected good recovery. At the age of 3 years, neurological examinations were normal as was the EEG at the age of 9 months. CT showed close to normal intracranial structures. CONCLUSION: This case report stresses the importance of antenatal vitamin K prophylaxis and the consideration of a primary Caesarean section in maternal vitamin K deficiency states and demonstrates the successful management of massive subdural haemorrhage by a limited surgical approach.

Hospitalizations leading causes for maternal disorders

Presenting the rates of obstetric admissions of women living in Paraná in 2010.Method: A descriptive study in which the admission information of the hospital system of the Unified Health System was analyzed. Data from women aged between 10 to 49 years available on the DATASUS website were analyzed, using percentage and according to primary diagnosis, age and Regional Health area.Results: The Rate of Obstetric Complications (RtOC) was 38%, increasing with the age of women. Complications of labor and delivery (10.5%), and pregnancy with abortive outcome (9.1%) were the diagnoses with highest RtOC. The RtOC ranged between 8.4% in Telêmaco Borba, until 62.6% in Ponta Grossa.Conclusion: The healthcare team should monitor the rates of admissions for obstetric complications as these indicate the quality of health care of women, mainly focused on labor, delivery and women of older age.


Satisfaction maternelle de la prise en charge anesthésique durant l'accouchement: une étude de cohorte rétrospective. [Risk factors associated with maternal satisfaction during childbirth: a retrospective cohort study.]

PURPOSE: Factors associated with maternal satisfaction of anesthetic management during labour and delivery are poorly known. The purpose of this study was to assess these factors. METHODS: We performed a retrospective cohort study on parturients admitted between January 2004 and December 2008. Data on patients' demographics, comorbidities, procedures performed and various aspects of their anesthetic experience were retrieved from the anesthetic records. Maternal satisfaction was measured using a numerical scale from 0 to 10 (0 = not satisfied at all, 10 = very satisfied). A cutoff of ≤ 6 was taken as poor satisfaction. We performed a multivariate analysis to identify the different predictors of maternal satisfaction and more specifically those related to pain, overall experience with the technique, delays, and presence of anesthetic, obstetrical and neonatal complications. RESULTS: There were 15,386 parturients admitted during the study period. Of these, 10,034 had complete information in the chart and 761 (7.6%) parturients were dissatisfied with their anesthetic care. Factors decreasing patient satisfaction were high risk pregnancy [odds ratio (OR) 95% confidence interval (CI) 0.59 (0.34-1.02)] and difficult delivery [OR (95% CI) 0.62 (0.52-0.74)]. Pain, a negative experience of the procedure, delays, poor coordination in management, and the presence of complications decreased patient satisfaction [OR (95% CI) 0.07 to 0.71]; P < 0.001. CONCLUSION: Maternal satisfaction with anesthesia care is largely determined by the effectiveness and correct performance of the procedure carried from the technical and human point of view. However, other factors such as a good coordination in patient management and the absence of complications also influence maternal satisfaction.
