    Background: Aetiology of preterm birth (PTB) is heterogeneous and preventive strategies remain elusive. Socio-environmental measures implemented as Ireland s prudent response to the SARS-CoV-2 virus (COVID-19) pandemic represented, in effect, a national lockdown and have possibly influenced the health and wellbeing of pregnant women and unborn infants. Cumulative impact of such socio-environmental factors operating contemporaneously on PTB has never been assessed before. Methods: Regional PTB trends of very low birth weight MESHD (VLBW) infants in one designated health area of Ireland over two decades were analysed. Poisson regression and rate ratio analyses with 95% CI were conducted. Observed regional data from January to April 2020 were compared to historical regional and national data and forecasted national figures for 2020. Results: Poisson regression analysis found that the regional historical VLBW rate per 1000 live births for January to April, 2001 to 2019 was 8.18 (95% CI: 7.21, 9.29). During January to April 2020, an unusually low VLBW rate of just 2.17 per 1000 live births was observed. The rate ratio of 3.77 (95% CI: 1.21, 11.75), p = 0.022, estimates that for the last two decades there was, on average, 3.77 times the rate of VLBW, compared to the period January to April 2020 during which there is a 73% reduction. National Irish VLBW rate for 2020 is forecasted to be reduced to 400 per 60,000 births compared to historical 500 to 600 range. Conclusion: An unprecedented reduction in PTB of VLBW infants was observed in one health region of Ireland during the COVID-19 lockdown. Potential determinants of this unique temporal trend reside in the summative socio-environmental impact of the COVID-19 dictated lockdown. Our findings, if mirrored in other regions that have adopted similar measures to combat the pandemic, demonstrate the potential to evaluate these implicated interdependent behavioural and socio-environmental modifiers to positively influence PTB rates globally.

    This systematic review and meta-analysis aimed to evaluate the impact of COVID-19 on pregnant women. We searched for qualified studies in PubMed, Embase, and Web of Science. The clinical characteristics of pregnant women with COVID-19 and their infants were reported as means and proportions with 95% confidence interval (CI). Nine studies involving with 93 pregnant women with COVID-19 and 103 infants were included in the meta-analysis. Pregnant women with COVID-19 have relatively mild symptoms. However, abnormal proportions of laboratory parameters were similar or even increased, compared to general population. Around 30% of pregnant women with COVID-19 experienced preterm delivery, whereas the mean birth weight MESHD was 3214.7g. Fetal death MESHD, severe neonatal asphyxia HP asphyxia MESHD, and detection of SARS-CoV-2 were observed in about 2%, whereas no neonatal death MESHD was found. In conclusion, the current review will serve as an ideal basis for future considerations in the treatment and management of COVID-19 in pregnant women.

    Background Existing evidence indicates that the risk of obstetric and perinatal outcomes is higher in women with coronavirus infection MESHD. outbreaks suggest that pregnant women and their fetuses are particularly susceptible to poor outcomes. However, there is little known about pregnancy related complications and co-morbidity in this group of women. Therefore, this, systematic review and meta-analysis performed in order to find out whether COVID-19 may cause different manifestations and outcomes in antepartum and postpartum period or not.Methods We searched databases, including Medline (PubMed), Embase, Scopus, Web of sciences, Cochrane library, Ovid and CINHAL to retrieve all articles reporting the prevalence SERO of maternal and neonatal complications, in addition clinical manifestations, in pregnant women with COVID 19 that published with English language from January to April 2020. Results 11 studies with total 177 pregnant women included in this systematic review.Results show that the pooled prevalence SERO of neonatal mortality, lower birth weight MESHD, stillbirth MESHD, premature birth MESHD premature birth HP, and intrauterine fetal distress MESHD fetal distress HP in women with COVID 19 were 4% (95% Cl: 1 - 9%), 21% (95% Cl: 11 – 31%), 2% (95% Cl: 1 - 6%), 28% (95% Cl: 12 - 44%), and 15% (95% Cl: 4 - 26%); respectively. Also the pooled prevalence SERO of fever MESHD fever HP, cough MESHD cough HP, diarrhea MESHD diarrhea HP and dyspnea MESHD dyspnea HP were 56% (95% Cl: 30 - 83%), 30% (95% Cl: 21 - 39%), 9% (95% Cl: 2 - 16%), and 3% (95% Cl: 1 - 6%) in the pregnant women with COVID-19.Conclusion According to this systematic review and meta-analysis, the pregnant women with COVID-19 with or without pneumonia MESHD pneumonia HP, are at a higher risk of pre-eclampsia MESHD eclampsia HP, preterm birth, miscarriage and cesarean delivery. Furthermore, the risk of LBW and intrauterine fetal distress MESHD fetal distress HP seems increased in neonates.

    Abstract Objective: The aim of this systematic review was to examine published and preprint reports for maternal and fetal outcomes in pregnant women with COVID-19 and also assess the incidence of maternal-fetal transmission TRANS of SARS CO-V-2 infection MESHD. Design : Systematic review Data sources:We searched PUMBED. Medline, Embase, MedRxiv and bioRxiv databases upto 31st March 2020 utilizing combinations of word variants for " coronavirus " or " COVID-19 " or " severe acute respiratory syndrome MESHD " or " SARS-COV-2 " and " pregnancy " . We also included data from preprint articles. Study selection : Original case reports and case series on pregnant women with a confirmed diagnosis of SARS-CoV-2 infection MESHD. Data extraction : We included 23 studies [China (20), USA (01), Republic of Korea (01) and Honduras, Central America (01) reporting the information on 172 pregnant women and 162 neonates. The primary outcome measures were maternal health characteristics and adverse pregnancy outcomes, neonatal outcomes and SARS-CoV-2 infection MESHD in neonates was extracted. Treatments given to pregnant women with COVID-19 were also recorded. Results: Out of 172 women affected by COVID-19 in pregnancy, 160 women had delivered 162 newborns (2 set of twins, 12 ongoing pregnancies). In pregnant women with COVID-19, the most common symptoms were fever MESHD fever HP (54%), cough MESHD cough HP (35%), myalgia MESHD myalgia HP (17%), dyspnea MESHD dyspnea HP (12%) and diarrhea MESHD diarrhea HP (4%). Pneumonia MESHD Pneumonia HP was diagnosed by CT scan imaging in 100 % of COVID-19 pregnant women. Pregnancy complications MESHD included delivery by cesarean section (89%), preterm labor (21%), fetal distress MESHD fetal distress HP (9%) and premature rupture of membranes HP rupture MESHD of membranes (8%). The most common co-morbidities associated with pregnant women with COVID-19 were diabetes (11%), hypertensive disorders (9%), placental disorders (5%), co- infections MESHD (6%), scarred HP uterus (5%), hypothyroidism MESHD hypothyroidism HP (5%) and anemia MESHD anemia HP (4%). Amongst the neonates of COVID-19 mothers, preterm birth (23%), respiratory distress HP syndrome MESHD (14%), pneumonia MESHD pneumonia HP (14%) low birth weight MESHD (11%), small for gestational age HP age TRANS (3%) were reported. There was one still birth and one neonatal death MESHD reported. Vertical transmission TRANS rate of SARS-CoV-2 is estimated to be 11%. Conclusion In pregnant women with COVID-19, diabetes and hypertensive disorders are common co-morbidities and there is a risk of preterm delivery. Amongst the neonates born to mothers with COVID-19, respiratory distress HP syndrome MESHD and pneumonia MESHD pneumonia HP are common occurrence. There is an evidence of vertical transmission TRANS of SARS-CoV-2 infection MESHD in women with COVID-19.

    Background: On December 2019, Novel coronavirus disease MESHD (COVID-19) was detected in Wuhan, China, and then spread around the world. There is little information about effects of COVID-19 on Pregnant women and newborns as a sensitive population. The current study is a systemic review and Meta-analysis to measure the risks and determine the presentations of COVID-19 in pregnant women and newborn. Methods: online data bases were searched on march 20. Heterogeneity of the included studies was assessed using the Cochran Q test and Higgins I2 statistic and expressed as percentage. All data were analyzed with 95% confidence intervals. Results: A total of 7 studies involving 50 participants with Positive test of COVID-19 were enrolled. Mean age TRANS of pregnant women was 30.57 years old and the Mean Gestational age TRANS was 36.9 weeks. Other variables such as Apgar score, birth weight MESHD, Sign and symptoms MESHD, Complications and Laboratory data were Analyzed. Conclusion: Our findings showed same clinical characteristics in pregnant women as in non-pregnant adults TRANS, with the main symptoms being cough MESHD cough HP and fever MESHD fever HP. No vertical transmission TRANS was seen and all patients delivered healthy neonates. Our findings would be of great help to the decision making process, regarding the management of pregnant women diagnosed with COVID-19.

    Abstract Background: With the exponential increase in coronavirus disease MESHD 2019 (COVID-19) worldwide, an increasing proportion of pregnant women are now infected during their pregnancy. The aims of this systematic review were to summarize the possible symptoms, treatments, and pregnancy outcomes of women infected with COVID-19 during their pregnancy. Methods: Four databases (Medline, Web of Science, Scopus, and CINAHL) were searched on March 25, 2020, using the following keywords: 'COVID-19', 'nCoV-2019', and 'coronavirus'. Articles included if they reported either the symptoms, treatments for the women who had been infected with the COVID-19 during their pregnancy or pregnancy outcomes. The selected articles' results were summarized employing a narrative synthesis approach. Results: A total of nine studies were selected for this study, comprising 101 infected pregnant women. Other than the infected general population, infected pregnant women reported different symptoms; however, fever MESHD fever HP (66.7%), cough MESHD cough HP (39.4%), fatigue MESHD fatigue HP (15.2%), and breathing difficulties (14.1%) were common. Infected pregnant women were given different treatments than the general infected population. The C-section was a common (83.9%) mode of delivery among infected pregnant women, and a higher proportion of births were preterm births (30.4%) and low birth weight MESHD (17.9%). Conclusions: Pregnant infected women had different symptoms, and they were given dissimilar treatments than the general infected population. Healthcare providers may have appropriately informed about these symptoms and treatments. They, therefore, would be able to handle infection MESHD during pregnancy effectively, which would reduce common adverse consequences among infected pregnant women.
