Risk factors for death in patients with sepsis admitted to an obstetric intensive care unit: A cohort study.

Improving understanding of the prognostic factors associated with death resulting from sepsis in obstetric patients is essential to allow management to be optimized. This retrospective cohort study aimed to determine the risk factors for death in patients with sepsis admitted to the obstetric intensive care unit of a tertiary teaching hospital in northeastern Brazil between April 2012 and April 2016.The clinical, obstetric, and laboratory data of the sepsis patients, as well as data on their final outcome, were collected. A significance level of 5% was adopted. Risk factors for death in patients with sepsis were evaluated in a multivariate analysis.During the period analyzed, 155 patients with sepsis were identified and included in the study, representing 5.2% of all obstetric intensive care unit (ICU) admissions. Of these, 14.2% (n = 22) died. The risk factors for death were septic shock at the time of hospitalization (relative risk [RR] = 3.45; 95% confidence interval [CI]: 1.64-7.25), need for vasopressors during hospitalization (RR = 17.32; 95% CI: 4.20-71.36), lactate levels >2 mmol/L at the time of diagnosis (RR = 4.60; 95% CI: 1.05-20.07), and sequential organ failure assessment score >2 at the time of diagnosis (RR = 5.97; 95% CI: 1.82-19.94). Following multiple logistic regression analysis, only the need for vasopressors during hospitalization remained as a risk factor associated with death (odds ratio [OR] = 26.38; 95% CI: 5.87-118.51).The need for vasopressors during hospitalization is associated with death in obstetric patients with sepsis.

Neurological outcomes of congenital Zika syndrome in toddlers and preschoolers: a case series.

BACKGROUND: Congenital Zika syndrome causes a spectrum of neurological symptoms with varying effects on function that require different therapeutic strategies. To date, this spectrum of effects and its clinical implications have not been completely described. We describe the neurological examination findings in toddlers and preschoolers, including predominant symptom complexes and comorbidities. METHODS: This study is a case-series neurological evaluation of 75 children with congenital Zika syndrome in Campina Grande, Brazil. The study is part of a cohort of children with congenital Zika syndrome that started in 2015 and is still ongoing. Children with Zika virus infection detected during pregnancy (mothers exhibited rash and were followed and diagnosed by fetal ultrasound abnormalities or RT-PCR) or through microcephaly screening after birth, using Intergrowth 21 guidelines, were selected by laboratory and radiological criteria. Children were examined during a 10-day period in September, 2018, and underwent neurological interview, examination, and assessment of functional outcomes and comorbidities. Children were divided in groups of predominant corticospinal or neuromuscular clinical signs and the associations between these groups and clinical comorbidities were assessed. FINDINGS: All of the children recruited to the study from Nov 29, 2015 to Nov 30, 2017 had imaging correlates of congenital Zika syndrome. Children were assigned to groups depending on the signs exhibited, either corticospinal or neuromuscular, with or without dyskinetic signs. 75 children completed the evaluation, 38 (51%) girls and 37 (49%) boys. Median age was 33 months (range 26-40 months; IQR 29-34). Microcephaly was present at birth in 56 (75%) children, and 19 (25%) children were born with normal head circumference, 15 of whom later developed microcephaly. Neurological examination grouped four children as having isolated dyskinetic signs, 48 children were assigned to the corticospinal group and 23 into the neuromuscular group. Dyskinetic findings were present in 30 (40%) children, either alone (four [5%]) or combined with corticospinal (19 [40%] of 48) or neuromuscular (seven [30%] of 23) findings. Comorbidities were highly prevalent, and the neuromuscular group had worse functional outcomes, evaluated by gross motor function (p=0·026), manual abilities (p=0·0013), and communication function (p<0·0005) classification scales, than the corticospinal group, whereas pneumonia (p<0·0005) and urinary tract infections (p<0·0005) were more frequent in the corticospinal group. Cortical hyperexcitability was supported by several clinical correlates, such as early onset epilepsy, persistence of primitive reflexes, and dystonia. INTERPRETATION: We describe distinct neurological profiles in the congenital Zika syndrome spectrum, with functional outcomes tending to correlate with these groups. The clinical division of children based on the disease signs proposed here is supported by the literature on central and peripheral nervous system pathology in congenital Zika syndrome. The high prevalence of dyskinetic symptoms merits special attention.

Misoprostol administered sublingually at a dose of 12.5 µg versus vaginally at a dose of 25 µg for the induction of full-term labor: a randomized controlled trial protocol.

BACKGROUND: Various methods are currently used for the induction of labor. Nevertheless, the most effective method with the fewest side effects remains to be established. Misoprostol, administered vaginally, has been routinely used for this purpose; however, other forms of administration are being proposed, including the use of sublingual tablets. No studies have yet compared the effectiveness and safety of 12.5-µg misoprostol administered sublingually compared to a 25-µg vaginal dose of the drug for the induction of labor. METHODS: A triple-blind, multicenter, placebo-controlled, randomized clinical trial will be conducted in Brazil at the Instituto de Medicina Integral Prof. Fernando Figueira and at the Assis Chateaubriand Maternity Teaching Hospital of the Federal University of Ceará. A total of 140 patients with full-term pregnancies, a live fetus, a Bishop score ≤ 6 and a recommendation of induction of labor will be randomized to one of two groups. One group will receive 12.5-µg sublingual tablets of misoprostol and placebo vaginal tablets, while the other group will receive placebo sublingual tablets and vaginal tablets containing 25 µg of misoprostol. The principal endpoint is the rate of tachysystole. The secondary endpoints are vaginal delivery within 24 h of induction, uterine hyperstimulation, Cesarean section, severe neonatal morbidity or perinatal death, severe maternal morbidity or maternal death, and maternal preference regarding the route of administration of the drug. Student's t-test, and the chi-square test of association or Fisher's exact test, as appropriate, will be used in the data analysis. Risk ratios and their respective 95% confidence intervals will be calculated. DISCUSSION: Misoprostol has been identified as a safe, inexpensive, easily administered option for the induction of labor, with satisfactory results. An experimental study has shown that misoprostol administered sublingually at a dose of 25 µg appears to be effective and is associated with greater maternal satisfaction when labor is induced in women with an unfavorable cervix. Nevertheless, the rate of tachysystole remains high; therefore, further studies are required to determine the ideal dose and the ideal interval of time between doses.

Intrapartum diagnosis and treatment of longitudinal vaginal septum.

Longitudinal vaginal septum is a rare Müllerian malformation that may be associated with dyspareunia, dysmenorrhea, primary amenorrhea, and infertility. In this report, the authors present a case of longitudinal vaginal septum in a 15-year-old patient with a full-term pregnancy whose diagnosis was only made during labor following bidigital vaginal and speculum examination. Septoplasty was performed during the second stage of labor. Both mother and child progressed satisfactorily and were discharged from hospital in good health. Six months later, ultrasonography, hysterosalpingography, and hysteroscopy were carried out and no other associated abnormality was found.

Factors associated with severe maternal morbidity and near miss in the São Francisco Valley, Brazil: a retrospective, cohort study.

BACKGROUND: Maternal mortality remains a major public health issue worldwide, with persistent high rates prevailing principally in underdeveloped countries. The objective of this study was to determine the risk factors for severe maternal morbidity and near miss (SMM/NM) in pregnant and postpartum women at the maternity ward of the Dom Malan Hospital, Petrolina, in northeastern Brazil. METHODS: A retrospective, cohort study was conducted to evaluate the sociodemographic and obstetric characteristics of the women. Patients who remained hospitalized at the end of the study period were excluded. Risk ratios (RR) and their respective 95% confidence intervals (95% CI) were calculated as a measure of relative risk. Hierarchical multiple logistic regression was also performed. Two-tailed p-values were used for all the tests and the significance level adopted was 5%. RESULTS: A total of 2,291 pregnant or postpartum women receiving care between May and August, 2011 were included. The frequencies of severe maternal morbidity and near miss were 17.5% and 1.0%, respectively. Following multivariate analysis, the factors that remained significantly associated with an increased risk of SMM/NM were a Cesarean section in the current pregnancy (OR: 2.6; 95% CI: 2.0 - 3.3), clinical comorbidities (OR: 3.4; 95% CI: 2.5 - 4.4), having attended fewer than six prenatal visits (OR: 1.1; 95% CI: 1.01 - 1.69) and the presence of the third delay (i.e. delay in receiving care at the health facility) (OR: 13.3; 95% CI: 6.7 - 26.4). CONCLUSIONS: The risk of SMM/NM was greater in women who had been submitted to a Cesarean section in the current pregnancy, in the presence of clinical comorbidities, fewer prenatal visits and when the third delay was present. All these factors could be minimized by initiating a broad debate on healthcare policies, introducing preventive measures and improving the training of the professionals and services providing obstetric care.

[Cervical ultrasonography versus Bishop score as a predictor of vaginal delivery]. / Ultrassonografia do colo uterino versus índice de Bishop como preditor do parto vaginal.

PURPOSE: to compare the accuracy of transvaginal ultrasonographic measurement of the uterine cervix with Bishop's score for the prediction of vaginal delivery after labor induction, with 25 mcg of misoprostol. METHODS: a prospective study for the validation of a diagnostic test was conducted on 126 pregnant women with indication for labor induction. The patients were evaluated by Bishop's score and transvaginal ultrasonography for cervical measurement. They also undergone obstetric transabdominal ultrasound to evaluate static and fetal weight, as well as the amniotic fluid index, and basal cardiotocography for the evaluation of fetal vitality. Labor was induced with vaginal and sublingual misoprostol, one of the tablets containing 25 mcg of the drug and the other only placebo. The tablets were administered every six hours, with a maximum number of eight. Frequency tables were obtained, and measures of central tendency and dispersion were calculated. ROC curves were constructed for the evaluation of Bishop's score and ultrasonographic measurement of the uterine cervix for the prediction of vaginal delivery. RESULTS: the area under the ROC curve was 0.5 (p=0.8) for the ultrasonographic measurement of the uterine cervix, and 0.6 (p=0.02) for Bishop's score (cut point ≥4). Bishop's score had a sensitivity of 56.2% and specificity of 67.9% for prediction of vaginal delivery, with a positive likelihood ratio of 1.75 and a negative one of 0.65. CONCLUSIONS: ultrasonographic measurement of the uterine cervix was not a good predictor of evolution to vaginal delivery among patients with misoprostol-induced labor. Bishop's score was a better predictor of vaginal delivery under these circumstances.

[Clinical and microbiological profile of women with bacterial vaginosis]. / Perfil clínico e microbiológico de mulheres com vaginose bacteriana.

PURPOSE: to study the clinical and microbiological profile of women with bacterial vaginosis participating in a randomized, double-blind clinical trial, which compared the vaginal use of preparations from red pepper tree and metronidazole for the treatment of genital discharge. METHODS: the study was conducted on a series of 277 women with bacterial vaginosis concomitantly diagnosed by the criteria of Amsel and Nugent, selected from a total of 462 recruited patients using the information obtained before intervention. Data were analyzed with the Epi-Info 3.32 software. In order to compare the outcomes frequencies between the intervention groups, the chi2 test was used and the risk ratio and 95% confidence interval were calculated. The intention to treat analysis was performed. In addition to the determination of diagnostic parameters, the culture of vaginal content and a Papanicolaou cytology test were also performed. RESULTS: the most frequent clinical complaints were genital discharge, observed in 206 participants (74.4%) and the fish odor of the vaginal secretion, which occurred in 68.6% of the cases (190 patients). Among the diagnostic clinical criteria, the presence of clue-cells was positive in 275 women (99.3%), the Whiff test, in 266 (96.0%), followed by pH >4.5, which occurred in 92.8% of the cases, and by the presence of fluid grayish discharge reported by 206 participants (74.4%). Regarding the Nugent criterion, the median score was 8.0. Culture of the vaginal content permitted the identification of Gardnerella vaginalis in 96.8% of cases and of Mobiluncus in 53.1%. Only one third of the exams showed the presence of Lactobacillus (89 women - 32.1%). Fungal growth occurred in the cultures of 14 participants (5.1%). In most cases, culture revealed the presence of Corynebacterium (94.2%), Gram-positive cocci (98.2%), as well as Gram-positive (99.3%) and Gram-negative (91.0%) bacilli. Oncotic colposcopy revealed a very scarce presence of lactobacilli, which were present in only 8 cytological exams (2.9%) out of the total of 273 exams performed. CONCLUSIONS: the results of the present study did not differ from the literature regarding the symptoms reported by the women, the clinical criteria most frequently observed in the diagnosis, or the bacterial species detected in cultures of vaginal content. These findings indicate the need for further studies that might better elucidate the interrelations between the microbiological findings and the clinical expression of bacterial vaginosis.

Uterine artery Doppler in the third trimester of pregnancy and postnatal outcome of patients with severe preeclampsia.

OBJECTIVES: To assess uterine artery Doppler velocimetry performed in the third trimester of pregnancy in women with severe preeclampsia as a predictor of adverse postpartum outcome. METHODS: A cohort study including 154 women, conducted in a teaching hospital in Recife, Brazil. Uterine artery Doppler was performed at admission to hospital and postpartum outcome was evaluated. RESULTS: High-resistance uterine artery Doppler was predictive of prolonged hospitalization and of being discharged from hospital under antihypertensive medication. No other correlation with maternal complications was found. CONCLUSION: High-resistance uterine artery Doppler in the third trimester of pregnancy is able to predict adverse postpartum outcome.

[Risk factors for macrosomia in newborns at a school-maternity in northeast of Brazil]. / Fatores de risco para macrossomia em recém-nascidos de uma maternidade-escola no nordeste do Brasil.

OBJECTIVE: to determine the frequency of macrosomia in babies born alive at a reference obstetric service, and its association with maternal risk factors. METHODS: a transversal descriptive study, including 551 women at puerperium, hospitalized at Instituto de Saúde Elpídio de Almeida, in Campina Grande (PB), Brazil, from August to October, 2007. Women, whose deliveries had been assisted at the institution, with babies born alive from one single gestation and approached in the first postpartum day, were included in the study. The nutritional and sociodemographic maternal characteristics were analyzed, and the ratio of macrosomia (birth weight >or=4.000 g) and its association with maternal variables were determined. Macrosomia was classified as symmetric or asymmetric according to Rohrer's index. Statistical analysis has been done through Epi-Info 3.5 software; the prevalence ratio (PR) and the confidence interval at 95% (CI 95%) were calculated. The research protocol was approved by the local Ethics Committee and all the participants signed the informed consent. RESULTS: the mean maternal age was 24.7 years old, and the mean gestational age was 38.6 weeks. Excessive gestational weight gain was observed in 21.3% of the pregnant women, and 2.1% of the participants had a diagnosis of diabetes mellitus (gestational or clinic). A ratio of 5.4% of macrosomic newborns was found, 60 were asymmetric. There was no significant association between macrosomia, mother's age and parity. There was an association between macrosomia and overweight/obesity in the pre-gestational period (PR=2.9; CI 95%=1.0-7.8) and at the last medical appointment (PR=4.9; CI 95%=1.9-12.5), excessive weight gain (PR = 6.9; CI 95%:2.8-16.9), clinical or gestational diabetes (PR = 8.9; CI 95%:4.1-19.4) and hypertension (PR=2.9; CI 95%=1.1-7.9). The factors that persisted significantly associated with macrosomia in the multivariate analysis were the excessive weight gain during the gestation (RR=6.9; CI 95%=2.9-16.9) and the presence of diabetes mellitus (RR=8.9, CI 95%=4.1-19.4). CONCLUSIONS: considering that excessive gestational weight gain and diabetes mellitus were the factors more strongly associated with macrosomia, it is important that precocious detection measurements and adequate follow-up of such conditions be taken, aiming at preventing unfavorable perinatal outcomes.

Vaginal misoprostol prior to diagnostic hysteroscopy in patients of reproductive age: a randomized clinical trial.

STUDY OBJECTIVE: To assess pain during and after diagnostic hysteroscopy in patients of reproductive age according to use of vaginal misoprostol. DESIGN: A randomized, triple-masked, controlled clinical trial (Canadian Task Force classification I). SETTING: Diagnostic center at Instituto Materno Infantil de Pernambuco-Brazil. PATIENTS: A total of 45 women of reproductive age underwent diagnostic anesthesia-free hysteroscopy. INTERVENTIONS: In all, 400 mg of vaginal misoprostol or placebo was administered to randomized patients before diagnostic hysteroscopy. MEASUREMENTS AND MAIN RESULTS: The clinical trial was interrupted in patients receiving misoprostol because of significant vaginal bleeding precluding the procedure (p = .0006). No significant difference existed in pain scores between the groups. Vaginal bleeding was the main side effect occurring in 11 patients of the misoprostol group. No vaginal bleeding occurred in the placebo group (p = .00002). CONCLUSION: In the doses used, vaginal misoprostol induced vaginal bleeding and precluded diagnostic hysteroscopy in patients of reproductive age that limits continuation of this line of research. Further studies are needed to reassess the use of the drug in patients of this age group.

Postpartum dexamethasone for women with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome: a double-blind, placebo-controlled, randomized clinical trial.

OBJECTIVE: The purpose of this study was to determine the effectiveness of postpartum dexamethasone in patients with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome. STUDY DESIGN: A prospective, randomized, double-blind trial was conducted in which 105 women with HELLP syndrome were enrolled and assigned randomly to treatment or placebo groups following delivery. Duration of hospital stay, maternal morbidity, and laboratory and clinical parameters were evaluated. RESULTS: There was no difference in maternal morbidity or mortality between the 2 groups. There was also no difference in duration of hospitalization and the need for rescue scheme or the use of blood products between groups. Linear model adjustments showed no significant difference between groups with respect to the pattern of platelet count recovery, aspartate aminotransferase, lactate dehydrogenase, hemoglobin, or diuresis. CONCLUSION: These findings do not support the use of dexamethasone in the puerperium for recovery of patients with HELLP syndrome.

[New formulation of sublingual misoprostol (25 mcg) for induction of labor]. / Nova formulação de misoprostol sublingual na indução do trabalho de parto.

OBJECTIVES: To determine effectiveness and safety of sublingual misoprostol in tablets of 25 mcg, given every 6 hours for induction of labor in high-risk pregnant women hospitalized in two teaching hospitals in the Northeast of Brazil. METHODS: An open, non-randomized clinical trial was conducted, including 40 women with high-risk pregnancies hospitalized at "Maternidade-Escola Assis Chateaubriand" and "Instituto Materno-Infantil de Pernambuco". All of them had gestational age >or= 37 weeks, alive fetus with good vitality and Bishop scores
