RESUMO

Background: This study aimed to describe the clinical characteristics of maternal deaths associated with COVID-19 registered in a collaborative Latin-American multi-country database. Methods: This was an observational study implemented from March 1st 2020 to November 29th 2021 in eight Latin American countries. Information was based on the Perinatal Information System from the Latin American Center for Perinatology, Women and Reproductive Health. We summarized categorical variables as frequencies and percentages and continuous variables into median with interquartile ranges. Findings: We identified a total of 447 deaths. The median maternal age was 31 years. 86·4% of women were infected antepartum, with most of the cases (60·3%) detected in the third trimester of pregnancy. The most frequent symptoms at first consultation and admission were dyspnea (73·0%), fever (69·0%), and cough (59·0%). Organ dysfunction was reported in 90·4% of women during admission. A total of 64·8% women were admitted to critical care for a median length of eight days. In most cases, the death occurred during the puerperium, with a median of seven days between delivery and death. Preterm delivery was the most common perinatal complication (76·9%) and 59·9% were low birth weight. Interpretation: This study describes the characteristics of maternal deaths in a comprehensive multi-country database in Latin America during the COVID-19 pandemic. Barriers faced by Latin American pregnant women to access intensive care services when required were also revealed. Decision-makers should strengthen severity awareness, and referral strategies to avoid potential delays. Funding: Latin American Center for Perinatology, Women and Reproductive Health.

RESUMO

BACKGROUND: The incidence of placenta accreta has increased in recent years and it has been suggested that the rising trend in cesarean delivery and other uterine surgery is the underlying cause. OBJECTIVE: To explore the magnitude of the effect of performing single and repeat cesarean deliveries or other uterine surgery on the incidence of placenta accreta. SEARCH STRATEGY: Relevant databases were searched for papers published before August 1, 2018, using terms including "accreta" and "cesarean." SELECTION CRITERIA: Cohort studies assessing the risk of placenta accreta according to women's history of uterine surgery. DATA COLLECTION AND ANALYSIS: Meta-analyses were performed to assess the risks associated between uterine surgery and placenta accreta, hysterectomy, and uterine rupture. The I2 statistic was used to examine between-study heterogeneity. MAIN RESULTS: The risk of placenta accreta in a second pregnancy increased for women who had undergone a cesarean in their first pregnancy compared with vaginal delivery (OR 3.02; 95% CI, 1.50-6.08). Absolute risk of placenta accreta increased with the number of previous cesareans. The risk of uterine rupture and hysterectomy was also associated with the number of cesareans. CONCLUSIONS: Risk of placenta accreta, hysterectomy, and uterine rupture increases with the number of previous cesarean deliveries. PROSPERO: CRD42016050646.

RESUMO

OBJECTIVE: To evaluate efficacy and outcomes of the autologous transobturator midurethral sling for treatment of stress urinary incontinence (SUI). METHODS: In a prospective cohort study, an autologous transobturator mid-urethral sling was used to treat SUI among women attending a university hospital in Montevideo, Uruguay, from June 2017 to July 2018. In the first phase, autologous tissue of the abdominis rectus fascia was collected. In the second phase, the midurethral sling was placed via the transobturator approach. Outcomes were measured every 3 months by the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) Score. Preoperative and postoperative results were compared by Wilcoxon test. RESULTS: Eighteen women with a median age of 51 years were enrolled. The median follow-up was 9 months (range 6-15 months). Overall, 17 women showed symptomatic improvement after the procedure. In a comparison of preoperative versus postoperative ICIQ-FLUTS questionnaires, improvement in the incontinence subscore was observed at 3 (P<0.001), 6 (P<0.001), and 12 (P=0.008) months. No severe complications were observed. CONCLUSION: Use of an autologous transobturator urethral sling was found to be technically feasible and safe for SUI, with good short-term outcomes. Longer follow up and larger series are needed to validate the procedure.

RESUMO

BACKGROUND: Every year millions of women around the world suffer from pregnancy, childbirth and postpartum complications. Women who survive the most serious clinical conditions are regarded as to have experienced a severe acute maternal complication called maternal near miss (MNM). Information about MNM cases may complement the data collected through the analysis of maternal death, and was proposed as a helpful tool to identify strengths and weaknesses of health systems in relation to maternal health care. The purpose of this study is to evaluate the performance of a systematized form to detect severe maternal outcomes (SMO) in 20 selected maternity hospitals from Latin America (LAC). METHODS: Cross-sectional study. Data were obtained from analysis of hospital records for all women giving birth and all women who had a SMO in the selected hospitals. Univariate and multivariate adjusted logistic regression models were used to assess the predictive ability of different conditions to identify SMO cases. In parallel, external auditors were hired for reviewing and reporting the total number of discharges during the study period, in order to verify whether health professionals at health facilities identified all MNM and Potentially life-threatening condition (PLTC) cases. RESULTS: Twenty hospitals from twelve LAC were initially included in the study and based on the level of coverage, 11 hospitals with a total of 3,196records were included for the final analysis. The incidence of SMO and MNM outcomes was 12.9 and 12.3 per 1,000 live births, respectively. The ratio of MNM to maternal death was 19 to 1, with a mortality index of 5.1 %. Both univariate and multivariate analysis showed a good performance for a number of clinical and laboratory conditions to predict a severe maternal outcome, however, their clinical relevance remains to be confirmed. Coherence between health professionals and external auditors to identify SMO was high (around 100 %). CONCLUSIONS: The form tested, was well accepted by health professionals and was capable of identifying 100 % of MNM cases and more than 99 % of PLTC variables. Altered state of consciousness, oliguria, placenta accrete, pulmonary edema, and admission to Intensive Care Unit have a high (LR+ ≥80) capacity to anticipate a SMO.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate whether the use of oxytocin during the first and second stages of labor is associated with a higher incidence of postpartum hemorrhage (PPH) in pregnant women who received active management of third stage of labor (AMTSL). STUDY DESIGN: A secondary data analysis from vaginal deliveries in a hospital-based cohort study from 24 maternity hospitals in South America. The primary outcomes that were analyzed were moderate PPH (≥500 mL of blood loss), severe PPH (≥1000 mL of blood loss), and need of blood transfusion. RESULTS: A total of 11,323 vaginal deliveries were included. The incidence of moderate and severe PPH was 10.8% and 1.86%, respectively. Overall, 36% of deliveries received AMTSL. There was no association between induced/augmented labor and moderate PPH (P = .753), severe PPH (P = .273), and blood transfusion (P = .603) in the population that received AMTSL. CONCLUSION: AMTSL should be recommended, regardless of whether pregnant women received oxytocin during the first and second stages of labor.

RESUMO

OBJECTIVE: To determine whether treatment with amoxicillin-sulbactam in women with threatened idiopathic preterm labour will prolong the gestation and reduce preterm birth rates in a Latin-American population. METHODS: A double-blind, placebo-controlled, randomized trial was conducted in 96 women who were hospitalized for preterm labour between 24 and 34 weeks of gestation at the Pereira Rossell Hospital, in Montevideo, Uruguay. The primary outcome measure was prematurity. The sample size was calculated a priori based on the hospital database. Statistical analyses were performed using the t-test, chi square, weighted mean difference (WMD) and relative risk (RR) with their confidence intervals (95% CI). Analysis by intention-to-treat. RESULTS: Out of 47 patients assigned for antibiotics, 43 completed the treatment. There were no significant statistical differences between antibiotics and placebo group in prematurity (RR:1.04, 95% CI: 0.59, 1.84), prolongation of pregnancy (WMD:0.23, 95% CI: -0.96, 1.42) and other perinatal outcomes. CONCLUSION: Antibiotics did not prove to have benefits in improving perinatal outcomes in this Latin American population.

RESUMO

OBJECTIVE: This study was undertaken to evaluate whether the administration of meperidine decreases the length of labor in patients with a diagnosis of dystocia during the first stage of labor. STUDY DESIGN: Women with term singleton pregnancies who received a diagnosis of dystocia and required an active management of labor were randomly assigned to receive either 100 mg of meperidine or placebo. The primary outcome measure was length of labor. RESULTS: Four hundred seven pregnant women were included. There were no significant statistical differences between meperidine and placebo groups in length of labor and operative delivery rates such as forceps and cesarean section by intention-to-treat analysis. Low Apgar scores, umbilical artery acidosis, and admission to neonatal care units were increased in the meperidine group. CONCLUSION: Because of the absence of any benefits in patients with dystocia in labor and the presence of harmful effects on neonatal outcomes, meperidine should not be used during labor for this specific indication.
