Views82See morePURPOSE: To analyze the impact of vaginal delivery after a previous cesarean section on perinatal outcomes. METHODS: Case-control study with selection of incident cases and consecutive controls. Maternal and perinatal variables were analyzed. We compared secundiparas who had a vaginal delivery after a previous cesarean delivery (VBAC) (n=375) with secundiparas who had a second cesarean section (CS) (n=375). Inclusion criteria were: secundiparas who underwent a cesarean section in the previous pregnancy; singleton and term pregnancy; fetus in vertex presentation, with no congenital malformation; absence of placenta previa or any kind of bleeding in the third quarter of pregnancy. RESULTS: The rate of vaginal delivery was 45.6%, and 20 (5.3%) women had forceps deliveries. We found a significant association between VBAC and mothers younger than 19 years (p<0.01), Caucasian ethnicity (p<0.05), mean number of prenatal care visits (p<0.001), time of premature rupture of membranes (p<0.01), labor duration shorter than 12 hours (p<0.04), Apgar score lower than seven at 5th minute (p<0.05), fetal birth trauma (p<0.01), and anoxia (p<0.006). In the group of newborns delivered by cesarean section, we found a higher frequency of transient tachypnea (p<0.014), respiratory disorders (p<0.048), and longer time of stay in the neonatal intensive care unit (p<0.016). There was only one case of uterine rupture in the VBAC group. The rate of neonatal mortality was similar in both groups. CONCLUSIONS: Vaginal delivery in secundiparas who had previous cesarean sections was associated with a significant increase in neonatal morbidity. Further studies are needed to develop strategies aimed at improving perinatal results and professional guidelines, so that health care professionals will be able to provide their patients with better counseling regarding the choice of the most appropriate route of delivery.

Views80See morePURPOSE: To evaluate the survival and complications associated with prematurity of infants with less than 32 weeks of gestation. METHODS: It was done a prospective cohort study. All preterm infants with a gestational age between 25 and 31 weeks and 6 days, born alive without congenital anomalies and admitted to the NICU between August 1st, 2009 and October 31st, 2010 were included. Newborns were stratified into three groups: G25, 25 to 27 weeks and 6 days; G28, 28 to 29 weeks and 6 days; G30, 30 to 31 weeks and 6 days, and they were followed up to 28 days. Survival at 28 days and complications associated with prematurity were evaluated. Data were analyzed statistically by c² test, analysis of variance, Kruskal-Wallis test, odds ratio with confidence interval (CI) and multiple logistic regression, with significance set at 5%. RESULTS: The cohort comprised 198 preterm infants (G25=59, G28=43 and G30=96). The risk of death was significantly higher in G25 and G28 compared to G30 (RR=4.14, 95%CI 2.23-7.68 and RR=2.84, 95%CI: 1.41-5.74). Survival was 52.5%, 67.4% and 88.5%, respectively. Survival was greater than 50% in preterm >26 weeks and birth weight >700 g. Neonatal morbidity was inversely proportional to gestational age, except for necrotizing enterocolitis and leukomalacia, which did not differ among groups. Logistic regression showed that pulmonary hemorrhage (OR=3.3, 95%CI 1.4-7.9) and respiratory distress syndrome (OR=2.5, 95%CI 1.1-6.1) were independent risk factors for death. There was a predominance of severe hemorrhagic brain lesions in G25. CONCLUSION: Survival above 50% occurred in infants with a gestational age of more than 26 weeks and >700 g birth weight. Pulmonary hemorrhage and respiratory distress syndrome were independent predictors of neonatal death. It is necessary to identify the best practices to improve the survival of extreme preterm infants.

Views77See morePURPOSE: To assess the prevalence of Streptococcus agalactiae, a Group B streptococcus, in pregnant women, and their possible risk factors, as well as the impact of perinatal colonization and antimicrobial susceptibility. METHODS: We evaluated 213 pregnant women from 20 weeks of gestation, regardless of risk factors, attending a tertiary teaching hospital. The technique used was a single sterile swab to collect secretions from the vaginal and perianal regions. The newly obtained samples were stored in Stuart transport medium and taken to the laboratory, where they were inoculated in Todd-Hewitt selective medium supplemented with Gentamicin (8 ug/mL) and nalidixic acid (15 ug/mL), with subsequent cultivation on blood agar plates. The materials were tested with Gram, catalase with hydrogen peroxide and CAMP (Christie, Atkins, Munch-Petersen), and results were serologically confirmed with the Streptococcal Grouping Kit, Oxoid®. The positive samples were tested for antimicrobial susceptibility. We also assessed socioeconomic, reproductive, clinical, and obstetric variables, and newborn care. Statistical analysis was performed with Epi-Info 6.04. RESULTS: The prevalence of colonization obtained by field tests was 9.8% by CAMP test, but only 4.2% by serology. The only protective factor was white skin color (p=0.01, 0.45>OR>0.94, 95%CI). There was no difference in prevalence of Group B streptococcus regarding other reproductive and obstetric variables. Infection occurred in only one of the newborns from colonized mothers; although it was revealed infection with Pseudomonas spp. High resistance to ampicillin (4/9), cephalothin (4/9), penicillin (4/9), erythromycin (3/9), clindamycin (7/9), and cloramphenicol (1/9) was detected. CONCLUSIONS: The infection rate was lower than that found in other studies, although a high rate of resistance to antibiotics commonly used for treatment was detected. Since there are no studies on the prevalence of Group B streptococcus in Ceará, we cannot perform a comparative analysis of the population, and further studies are needed with geographically similar groups to validate these results.

Views140See morePURPOSE: to assess the influence of physiotherapy performed during radiotherapy (RT) on the quality of life (QL) of women under treatment for breast cancer. METHODS: this was a randomized clinical trial conducted on 55 women under RT treatment, 28 of whom were assigned to a group submitted to physiotherapy (PG) and 27 to the control group receiving no PG (CG). The physiotherapy technique used for PG was kinesiotherapy for the upper limbs using 19 exercises actively performed, with a series of ten rhythmic repetitions or stretching movements involving flexion, extension, abduction, adduction, internal and external shoulder rotation, separate or combined. QL was evaluated using the Functional Assessment of Cancer Therapy-Breast (FACT-B), at the beginning and at the end of RT and six months after the end of RT. The physiotherapy sessions were started concomitantly with RT, 90 days after surgery, on average. RESULTS: there was no difference between subgroups regarding the following subscales: physical well-being (p=0.8), social/family well-being (p=0.3), functional well-being (p=0.2) and breast subscale (p=0.2) at the three time points assessed. A comparison of the emotional subscale applied at the three evaluations demonstrated a better behavior of PG as compared to CG (p=0.01), with both groups presenting improvement on the breast subscale between the beginning and the end of RT (PG p=0.0004 and CG p=0.003). There was improvement in FACT-B scores at the end of RT in both groups (PG p=0.0006 and CG p=0.003). However, at the sixth month after RT, this improvement was maintained only in PG (p=0,005). QL assessed along time by the FACT B (p=0.004) and the Trial Outcome Index (TOI) (sums of the physical and functional well-being subscales and of the breast subscale) was better for PG (p=0.006). There was no evidence of negative effects associated with the exercises. CONCLUSIONS: the execution of exercises for the upper limbs was beneficial for QL during and six months after RT.

Views94See morePURPOSE: to evaluate the prevalence of spontaneous and induced abortion reported by a sample of Brazilian women interviewed in the National Demographic Health Survey of 1996. METHODS: this was a secondary analysis of the Brazilian DHS-96 database, with information from interviews with a representative sample of 12,612 women about their reproductive life, focusing on the prevalence of spontaneous and induced abortion in the last five years and the associated factors for the various regions of the country and for Brazil as a whole. The sampling method was implemented with a strategy selection in two stages, one for the households and the other for women. The prevalence of spontaneous and induced abortion was estimated for Brazil and regions, and the socio-demographic characteristics of the women were analyzed as a function of the abortion's experience. A multinomial regression model analysis was used for the identification of factors independently associated with both types of abortion; their OR and respective 95% CI are reported. RESULTS: the prevalence of reported spontaneous abortion was 14% and the prevalence of induced abortion was 2.4% for the country as a whole. The state with the highest prevalence of induced abortion was Rio de Janeiro with 6.5%, followed by the Northeast region with 3.1%. The places with the lowest prevalence were the state of São Paulo and the South region. Both spontaneous and induced abortion showed higher prevalences with increasing age of the women studied. Being from the urban area (OR=1.5; 95%CI=1.0-2.3), having had more than one live child (OR=2.2; 95%CI=1.5-3.2) and being non-white (OR=1.4; 95%CI=1.0-1.8) were the main risk factors for induced abortion. CONCLUSIONS: the non-modifiable risk factors for induced abortion identified in this study indicate the need for improvement of educational and contraceptive actions, with priority for these specific demographic groups.

Views70PURPOSE: to apply geoprocessing techniques for the spatial birth profile analysis of each municipality. METHODS: ecological and exploratory study, using data from the Health Information System about born alive babies in 2004, and using geoprocessing techniques. The spatial autocorrelations of the variables: cesarean section, mother's schooling, low birth weight, Apgar score at five minutes, prematurity, number of medical appointments and adolescent mothers, besides the map with the index of human development were estimated. For the detection of spatial events aggregates, Moran's I M statistics, through the program Terra View 3.13 (developed by INPE and available to the public) was used. Spatial maps with those variables were built, and Pearson's correlation coefficients, estimated. RESULTS: results have shown that the rate of born alive babies, from mothers with school level over primary school and from cesarean sections, presented a spatial pattern visually identifiable and significant spatial self-correlation. Low birth weight, prematurity, Apgar score, number of pre-natal appointments and adolescent mothers have presented a random spatial pattern, showing that, in this analysis scale, those markers have not discriminated the risk groups, despite their unquestionable predictive value for children's morbidity-mortality at individual level. There has been a positive correlation between cesarean section and schooling, and between cesarean section and human development index; and a negative correlation between adolescent mothers and human development index, with statistical significance (p<0.05). CONCLUSIONS: this methodology has allowed us to identify spatial clusters for the variables cesarean section and mother's schooling, besides deepening our knowledge on birth profile in the municipalities, presenting good potential on how to direct actions for specific areas.

Views78See morePURPOSE: to assess the prevalence and risk factors associated with near miss and other severe maternal morbidity at a reference tertiary maternity. METHODS: this is a cross-sectional study on severe maternal morbidity at the Hospital e Maternidade Celso Pierro, Campinas, São Paulo, between October 2005 and July 2006, identified from infirmary, admission and delivery unit logbooks. Pregnant and post-partum women with severe maternal morbidity were identified according to clinical criteria proposed by Waterstone. Later, cases with more severe morbidity, called extremely severe maternal morbidity, were reclassified using Mantel criteria, based on organic dysfunction and clinical management. RESULTS: there were 114 severe maternal morbidity cases among 2,207 birth deliveries, with a ratio of other severe morbidity and extremely severe morbidity near miss of 44.9 and 6.8 cases/1,000 live births, respectively. Mean gestational age at delivery was 35 weeks, and 87% came from the reference area for the maternity service. Hypertension (severe pre-eclampsia) represented 96% of other severe morbidity, while hemorrhage represented 60% of all extremely severe cases, followed by hypertension. The prevalence of extremely severe morbidity among the severe morbidity cases was not associated with marital status, schooling, maternal age, type of delivery, parity, gestational age at birth and home place. CONCLUSIONS: the other morbidities were 6.6 times more frequent than near miss, and it was not possible to differentiate both groups by epidemiological risk factors.

Views60See moreIn Brazil, where 90% of the childbirths occur in hospitals, 67.1% of the cases of maternal death are due to direct obstetric causes, mainly hypertensive disorders, but a quarter of the deaths are due to indirect obstetric causes. As maternal death is a rare event, estimated in 76/100,000, the study of severe maternal morbidity, following international literature, can contribute to qualify obstetrical care. Maternal morbidity is a continuum that ends with death, but there is a separate group, with extreme severity, known as near miss. From the literature review, there are the difficulties to obtain an operational definition of the cases of extremely severe morbidity or near miss. The prevalence ranged from 0.80-8.23%, according to the defining criteria and health care provided at the region. The characterization of severe maternal morbidity and near miss allows for monitoring the process of obstetrical care and could help to qualify treatment of maternal urgencies and emergencies, interrupting the process that can lead to death.
