Background During the COVID-19 pandemic, some studies describing different aspects of the infection included very similar participants, rising suspicion about double reporting. We aimed to evaluate the Gantt chart as a tool to highlight possible double reporting. The chart is routinely used in business applications to depict tasks of a project, by plotting horizontal bars against time, showing their time span and overlaps. Methods All case reports and case series of pregnant women with COVID-19, published by July 15, 2020, were included. Initial and final dates of participants’ enrollment, country, city, hospital, and number of pregnancies were plotted in the Gantt chart. Bars stand for enrollment dates of each study, according to hospital and city, thus allowing comparisons. Results We included 116 articles in the present analysis. The Gantt chart highlighted papers in which some participants were likely the same, thus allowing easier identification of double reporting of cases. Combining all information and pregnancy characteristics and outcomes helped to recognize duplications when the authors did not acknowledged the previous publication. Conclusions Unintended double reporting may occur, especially in exceptional times. The Gantt chart may help researchers to visually identify potential duplications, thus avoiding biased estimates in systematic reviews or meta-analysis.

“…Reichelt et al [30] reported that the prevalence of obesity and hyperglycemia were increased in pregnancies complicated with severe SARS-CoV-2 infection. The pandemic confinement also increased the risk of hypothyroxinemia during the first and second trimesters of pregnancy [31].…”

Objective: This meta-analysis aimed at comparing obstetric and perinatal outcomes in laboratory-tested pregnant women for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection before delivering. Method: We performed a comprehensive systematic review of electronic databases for studies reporting pregnant women with and without SARS-CoV-2 infection, as determined by polymerase chain reaction (PCR) before delivery, during the pandemic period published up to June 25, 2021. Results are reported as mean difference (MD) or odds ratio (OR) and their 95% confidence interval (CI). Results: Seventeen observational studies with low to moderate risk of bias, reported on 2,769 pregnant women with a positive SARS-CoV-2 PCR test and 13,807 with a negative test. Pregnant women with a positive PCR test delivered at an earlier gestational age (MD À0.19; 95% CI À0.36 to À0.02 weeks), smoked less (OR 0.75; 95% CI 0.61-0.94) and were associated with higher odds for preeclampsia (OR 1.30; 95% CI 1.09-1.54), NICU admissions (OR 2.37; 95% CI 1.18-4.76), stillbirths (OR 2.70; 95% CI, 1.38-5.29), and perinatal mortality (OR 3.23; 95% CI 1.23-8.52). There were no significant differences between positive and negative tested women in terms of nulliparity, multiple pregnancies, gestational diabetes, route of delivery, labor induction, preterm birth, infant birth weight, 5 min Apgar scores < 7, small-for-gestational-age infants and fetal malformations. Eleven studies included neonatal PCR SARS-CoV-2 testing which was performed on 129 infants, of which 20 were positive. Conclusion: Positive SARS-CoV-2 tested pregnant women had higher odds for preeclampsia/ hypertensive disorders of pregnancy, NICU admissions, stillbirths and perinatal mortality.

Background Some maternal characteristics indicate worse prognosis in pregnant women with coronavirus disease 2019 (COVID‐19). Objective To describe the prevalence of endocrine disorders in pregnancies involving COVID‐19, and its impact on maternal outcomes. Search strategy Search terms were “pregnancy” and “COVID‐19”. Selection PubMed, Embase, medRxiv, and Cochrane worksheet from February to July 2020 were searched. Data collection and analysis Articles describing endocrine disorders in pregnancies with and without COVID‐19 involvement were considered. We performed meta‐analyses of prevalence using random‐effect models and estimated relative risk and 95% confidence intervals (CI) of maternal outcomes relative to presence of endocrine disorders. Main results Articles included (n = 141) were divided into three data sets: individual (119 articles, 356 women), case series (17 articles, 1064 women), and national registries (7 articles, 10 178 women). Prevalence of obesity ranged from 16% to 46% and hyperglycemia in pregnancy (HIP) ranged from 8% to 12%. In data set 1, HIP and obesity were risk factors for severe disease in crude and age‐adjusted models, although not for intensive care unit admission. In data from two national registries, risk of dying was 5.62 (95% CI 0.30–105.95) in women with diabetes and 2.26 (95% CI 1.03–4.96) in those with obesity. Conclusion Obesity and HIP were prevalent in pregnant women with severe COVID‐19.
