Maternal and Neonatal Outcomes Associated With COVID-19 Infection in Pregnant Mothers Admitted in Tertiary Care Hospital in Central State of India.

In spite of various reports on perinatal outcomes of coronavirus disease 2019 (COVID-19) during pregnancies, the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on unborn babies and pregnant mothers are still mysterious. The goal of our research is to examine the perceived fetomaternal outcomes of COVID-19 during pregnancy. A total of 396 pregnant women were admitted to the Department of Gynaecology and Obstetrics, Pt. JNM Medical College, Raipur, Chhattisgarh, India, during the period from July 20, 2020 to January 6, 2021. The presence of SARS-CoV-2 in different biological samples was recorded via positive quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) test results. All the newborns delivered from the infected pregnant mothers were tested as RT-PCR negative. Negative findings of RT-PCR for respiratory swabs of newborns, amniotic fluid, placental tissue, breast milk, vaginal swabs, and cord blood indicated no transmission of the virus from mother to baby. However, maternal outcomes, such as hospitalization (46.96%), preeclampsia (13.88%), pre-term birth (14.39%), prelabor rupture of membranes (PROM) before 34 weeks (3.78%), PROM before 37 weeks (2.77%), vaginal bleeding (4.29%), postpartum hemorrhage (2.52%), pregnancy-induced hypertension (1.51%), and neonatal outcomes such as low birth weight ≤1.5 kg (6.59) and 1.6-2.4 kg (39.34%), intrauterine deaths (IUD) (0.50%), fetal distress (22.33%), NICU admission (5.58%), meconium-stained liquor (14.46%), diarrhea (0.25%), and low APGAR score 4-6 at 1 min (20.54%), were observed. The results of the present study indicate that SARS-CoV-2-induced complications during pregnancy must be taken seriously. Intrauterine fetal deaths occurred at lower rates. There is no substantial proof of vertical perinatal transmission of the virus, as none of the neonates had tested positive for COVID-19.

Did the first wave of the COVID-19 pandemic impact the cesarean delivery rate? A retrospective cohort study at a primary care center in Switzerland.

OBJECTIVES: During the first 3 months of the coronavirus disease 2019 (COVID-19) pandemic, our hospital's quality management team determined a decline in the rate of cesarean deliveries (CD). Thus, in this study we examined both the factors associated with this decrease as well as neonatal outcomes. METHODS: This was a retrospective observational cohort study comparing deliveries (n=597) between March and May 2020 (first nationwide "lockdown" in Switzerland) with those during the same period in 2018 and 2019 (n=1,063). A multivariable logistic regression analysis was used to examine the association between CD and the pandemic, adjusting for relevant risk factors for CD. RESULTS: The overall rate of CD during the pandemic period was lower (30.0%), than during the pre-pandemic period (38.7%, unadjusted odds ratio 0.68, 95% confidence interval [95%CI]: 0.55 to 0.84, p=0.0004) a result that was supported by the adjusted odds ratio (0.73, 95%CI: 0.54 to 0.99, p=0.04). CONCLUSIONS: The results of this study confirmed a significant reduction in the rate of CD in early 2020, during the first lockdown period due to COVID-19, but without major differences in maternal and infant health indicators or in obstetric risk factors than before the pandemic. These results may have been due to a difference in the composition of the obstetric team as well as the behavior of the obstetrics team and in the patients during the pandemic, given the burden it placed on healthcare systems. However, this hypothesis remains to be tested in further research.

Can Prenatal Ultrasound Predict Adverse Neonatal Outcomes in SARS-CoV-2 Affected Pregnancies?

BACKGROUND: Based on available data, at least one ultrasound assessment of pregnancies recovering from SARS-CoV-2 infection is recommended. Reports, however, on prenatal imaging findings and potential associations with neonatal outcomes following SARS-CoV-2 infection in pregnancy have been inconclusive. OBJECTIVE: We aim to describe the sonographic characteristics of pregnancies after confirmed SARS-CoV-2 infection and assess the association of prenatal ultrasound (US) findings with adverse neonatal outcomes (ANO). STUDY DESIGN: This is an observational prospective cohort study of pregnancies diagnosed with SARS-CoV-2 by reverse transcription polymerase chain reaction between March 2020 and May 2021. Prenatal US evaluation was performed at least once after diagnosis of infection with the following parameters measured: standard fetal biometric measurements, umbilical and middle cerebral artery Dopplers, placental thickness, amniotic fluid volume, and anatomic survey for infection-associated findings. The primary outcome was composite ANO, defined as one or more of the following: preterm birth, NICU admission, small for gestational age (SGA), respiratory distress, intrauterine fetal demise, neonatal demise, or other neonatal complications. Secondary outcomes were sonographic findings stratified by trimester of infection and severity of SARS-CoV-2 infection. Prenatal US findings were compared with neonatal outcomes, severity of infection, and trimester of infection. RESULTS: A total 103 SARS-CoV-2 affected mother-infant pairs with prenatal US evaluation were identified; 3 cases were excluded due to known major fetal anomalies. Of the 100 included cases, neonatal outcomes were available in 92 pregnancies (97 infants); of these, 28 (29%) had a composite ANO. Twenty-three (23%) had at least one abnormal prenatal US finding. The most common abnormalities seen on US were placentomegaly (11/23, 47.8%) and fetal growth restriction (FGR) (8/23, 34.8%). FGR was associated with a higher rate of a composite ANO (25% vs 1.5%; aOR: 22.67; 95% 95% CI, 2.63-194.91; p<0.001), even when SGA was removed from the composite ANO. Cochran-Mantel Haensel test controlling for possible FGR confounders continued to show this association (relative risk, 3.7; 95% confidence interval, 2.6-5.9; p<0.001). Median estimated fetal weight (EFW) and birthweight were lower in patients with a composite ANO (p<0.001). Infection in the third trimester was associated with lower median percentile of EFW (p=0.019). An association between placentomegaly and third trimester SARS CoV-2 infection was noted (p=0.045). CONCLUSION: In our study of SARS-CoV-2 affected maternal-infant pairs, rates of FGR were comparable to the general population. However, composite ANO rates were high. Pregnancies with FGR after SARS-CoV-2 infection were associated with an increased risk for ANO and may require close surveillance.

ABSTRACT Introduction : The pandemic of coronavirus disease 2019 (COVID-19) has spread to more than 100 countries. Specific information about its behavior in pregnancy is still limited. Objective: To describe the maternal and perinatal characteristics of pregnant patients infected with COVID-19 and their newborns in a tertiary referral hospital. Methods : Descriptive study. Subjects were all pregnant patients admitted to the OB/ GYN Emergency Department of the Edgardo Rebagliati Martins National Hospital from March 24 to May 7, 2020, who were diagnosed with SARS-CoV-2 infection by rapid test or by RT-PCR test. Medical and hospital records were reviewed to retrieve sociodemographic data, patient's history, clinical manifestations, maternal serology, obstetric complications, delivery mode and perinatal aspects. Results : 41 patients diagnosed with SARS-CoV-2 were identified. 9.2% of all admissions had a positive rapid test. The most common symptoms were cough in 84.6%, fever in 76.9% and sore throat in 61.5%. 68.2% of the patients were asymptomatic, 19.5% had mild illness and 7.3 %, moderate. 2 cases progressed to severe pneumonia requiring non-invasive ventilation. No maternal deaths were recorded. 21.7% were vaginal deliveries, while 78.3% were C-sections. One baby born in a vaginal delivery had a positive PCR result on day 8. Conclusions : A large percentage of asymptomatic pregnant patients had a positive PCR test. Implementing universal screening among patients in labor as part of the pregnant patient flow protocol is necessary for all institutions.

Maternal oxygenation and neonatal outcome in pregnant women with COVID-19: A case series of 20 patients

Purpose: Management of delivery in pregnant women with coronavirus disease 2019 (COVID-19) is mainly based on extrapolated evidence or expert opinion. This study aimed to assess the clinical manifestations and maternal and perinatal outcomes of COVID-19 during pregnancy. Methods: We retrospectively reviewed the cases of 20 pregnant women infected with the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their demographic data and clinical characteristics, including symptoms, laboratory examination, and imaging findings, were evaluated. We also assessed the delivery method and timing and clinical courses of mothers, including oxygenation and treatment for COVID-19, as well as neonatal outcomes. Results: The most common symptoms were fever (65%) followed by cough (45%). Seven cases (35%) of preterm birth were observed. Eight patients (40%) required oxygen administration during pregnancy. Among them, two patients (10%) required a high-flow nasal cannula, and one patient (5%) required venovenous extracorporeal membrane oxygenation (VV-ECMO). No maternal death was observed;however, one instance of severe neonatal asphyxia and one intrauterine fetal death were observed. Conclusion: Although most pregnant women with COVID-19 were discharged without any major complications, some cases became severe. Therefore, the timing and method of delivery should be considered for each case to control maternal and infant respiratory conditions.

To Compare the Maternal and Fetal Outcomes of COVID-19-Affected Expectant Mothers During the First and Second COVID-19 Waves: Data From a Tertiary Care Referral Hospital in Punjab.

BACKGROUND: Coronavirus 2019 (COVID-19) infection, declared pandemic in March 2020 by the World Health Organization, paved the way for newer research in the field of medicine. The second wave, beginning in March 2021, appeared to be more devastating. The purpose of this study is to evaluate the clinical characteristics, effects of COVID-19 infection in pregnancy, and obstetric and perinatal outcomes in the first and second waves. MATERIALS AND METHODS: This study was conducted from January 2020 to August 2021 at the Guru Gobind Singh Medical College and Hospital, Faridkot, Punjab. The patients were enrolled immediately after each infected woman was identified as per the inclusion and exclusion criteria. Demographic details of the patients, associated comorbid conditions, intensive care unit (ICU) admission, and treatment details were noted. Neonatal outcomes were recorded. The testing of pregnant women was done as per the Indian Council of Medical Research (ICMR) guidelines. RESULTS: There were 3421 obstetric admissions and 2132 deliveries during this period. Group 1 had 123 COVID-19-positive admissions, while group 2 had 101 admissions. The incidence of COVID-19 infection in pregnancy was 6.54%. In both groups, the majority of patients were between the ages of 21 and 30. About 80(66%) of the admissions in group 1 and 46(46%) in group 2 were in the gestational age of 29-36 weeks. Multiparity was more common in both groups, with 58% of cases in group 1 and 79% of cases in group 2. Obstetric comorbidities were common in both groups, seen in 46% of cases in group 1 and 78% of cases in group 2. The majority of patients were asymptomatic in group 1, with an 89% incidence, whereas only 33% of patients in group 2 were without symptoms. In biological data, D-dimers, prothrombin time, and platelet count were altered in 11%, 14%, and 17% of cases, respectively, in group 2, with almost normal data in group 1. Most cases in group 2 (52%) were critical cases in the moderate and severe categories requiring intensive care unit (ICU) treatment, whereas there was only single ICU admission in group 1. The overall case fatality rate (CFR) in group 2 was found to be 19.8(20/101).  Delivery by cesarean section was done in 38.2% of cases in group 1, while in 33% of cases in group 2, with a significant p-value of 0.001. About 29% of cases in group 1 and 34% of cases in group 2 underwent vaginal delivery. The rate of abortion was almost similar in both groups. Only two cases in group 1 and nine cases in group 2 had intrauterine fetal death. Observations of neonatal outcomes suggested that five cases in group 2 and two cases in group 1 had severe birth asphyxia. Only one case in group 1 and four cases in group 2 had positive COVID-19 status. Maternal mortality was significantly higher in group 2 with 20 cases, while only one case was in group 1. Anemia and pregnancy-induced hypertension were the chief comorbidities in this group. CONCLUSION: COVID-19 infection during pregnancy may be associated with maternal mortality while having a minimal effect on neonatal morbidity and mortality. The possibility of maternal-fetal transmission cannot be ruled out completely. The severity and characteristics of COVID-19 may vary in each wave, and we need to modify treatment strategies. More studies or meta-analyses reports are required to authenticate this transmission.

Perinatal Transmission of SARS-CoV-2 Infection and Its Clinical Attributes: A Single-Center Study From Western Uttar Pradesh.

Background Globally, severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) has infected millions of people to date. The morbidity and mortality associated with SARS-CoV-2 are higher in diabetics than those with chronic kidney disease and in the elderly. In pregnant women, it causes an increased risk for preeclampsia/eclampsia, infections, intensive care unit (ICU) admission, maternal mortality, and preterm birth. In neonates, SARS­CoV­2 infection has been found to cause stillbirths, growth retardation, premature delivery, increased neonatal intensive care unit (NICU) admission, and need for oxygen support. The neonate can get infected by vertical or horizontal transmission. As most studies have focussed on transmission at the time of birth only, in this study, we explored both vertical and horizontal transmission along with the clinical attributes of those born to mothers with SARS­CoV­2 infection. Methodology A prospective observational study was conducted in the Department of Pediatrics of a tertiary care hospital over 12 months from October 2020 to October 2021. All reverse transcription-polymerase chain reaction (RT-PCR) SARS-CoV-2-positive pregnant females admitted to the facility during the study duration were included. The enrolled mothers were followed till delivery. The mothers and neonates were managed per standard guidelines. Delivery details and neonatal outcomes were recorded. Coronavirus disease 2019 sampling in newborn babies was done at birth (within 24 hours) using a nasopharyngeal swab sample for RTPCR along with cord blood for SARS-CoV-2 immunoglobulin M (IgM). Complete blood count, C-reactive protein, serum electrolytes, random blood sugar, and chest X-ray were obtained for all babies at birth and thereafter according to requirement. In those roomed in with their mother, RT-PCR was repeated at the time of discharge or if they became symptomatic. Results A total of 44 mother-neonate dyads were included in the study. Cord blood IgM for SARS­CoV­2 was negative for all neonates, while throat swab RT-PCR was positive for two (4.5%) neonates immediately after birth. Overall, 13.6% of the neonates were premature, 27.2% of the neonates had low birth weight (<2,500 g), and 6.8% had very low birth weight (<1,500 g). Among those admitted to the NICU, 18.2% had respiratory distress; 4.5% had fever, lethargy, and poor feeding; and hyperbilirubinemia requiring phototherapy was observed in 11.3% of the neonates. Moreover, 4.5% of the neonates had hypocalcemia on initial investigations. Mortality was seen in 2.2% (1/44) of the neonates. Rooming-in and breastfeeding were seen in 68.2% of the neonates. The horizontal transmission was seen in one (3.3%) roomed-in neonate. Conclusions Perinatal transmission of SARS­CoV­2 infection does occur but its rate is not significant. Furthermore, with proper infection prevention and control measures, the risk of perinatal transmission can be decreased. Breastfeeding and rooming-in do not increase infection transmission if the mother takes all precautions.

Perinatal Outcome in Maternal COVID-19 infection at a Tertiary care Institute- A cross Sectional Study.

Abstract: COVID 19 pandemic is one of the biggest challenge to health system of developing as well as developed countries. Because of the novelty of the virus, limited data were available regarding perinatal outcome. The objective of this study is to find out the perinatal outcome in COVID-19 infected mothers who delivered during COVID Pandemic. Methodology: A cross sectional study was carried out at PCMC'S Post-Graduate Institute and YCM Hospital Pune (Maharashtra) from 1 May 2020 to 31 October 2021 which was a dedicated COVID hospital during COVID pandemic. A total of 362 maternity patients (including 5 twin pregnancies) having COVID 19 infection who gave birth to 367 Newborns were studied. Maternal COVID -19 infection was diagnosed either by RTPCR test or Rapid Antigen test. Demographic variables, maternal symptoms, labour and neonatal outcome were recorded. RT PCR of neonates at birth was performed. Data was analyzed statistically by using Epi Info Software. Aim: To analyze the perinatal outcome among COVID-19 infected mothers who delivered during Covid pandemic. Objectives: Study was conducted with the primary objective to analyze the labour outcome, maternal symptoms and secondarily to study maternal demographic profile and to compare disease severity during 1st and 2nd wave of COVID and to detect possibility of vertical transmission of COVID-19 in neonates of covid positive mothers. Results: 74.2% patients from young reproductive age (21-30 years age) were affected. All socioeconomic classes were affected. 61% patients were multigravida. Normal BMI was noted in 49.8%. 28.2% deliveries were preterm. Caesarean section rate was 50.5%. Following obstetric high risk factors were noted-anaemia in 34.2% followed by previous LSCS in 26.2% cases and preeclampsia in 18.7%Overall 54.6% patients were asymptomatic while 45.4% were symptomatic. Symptomatology between 1st and 2nd wave showed statistical significance (p value < .05%) for mild, moderate and severe symptoms. Myalgia, cough, fever and fatigue were common presenting symptoms. 14% patients required ICU/HDU care. HDU/ICU requirement showed statistical significance (p value < .05) between 1st and 2nd wave. Overall maternal mortality was 1.1% (4 maternal deaths in 2nd wave) with no mortality in 1st wave.96.4% were live births. Birth weight was more than 2.5 kg in 62% cases and 21.3% cases required NICU. Vertical transmission of COVID was seen in 1.1% cases. Conclusion: Pregnant patients with moderate and severe disease are at higher risk of perinatal complications. ICU/HDU management with multidisciplinary management may reduce morbidity and mortality. Neonatal affection due to COVID may not be severe but may increase prematurity due to iatrogenic intervention.

The Incidence and Outcomes of Late-Term Pregnancy.

BACKGROUND: Little is known about the outcomes of late-term pregnancy. In this study, we aim to assess the incidence and adverse prenatal outcomes associated with late-term pregnancy. METHODS: We retrospectively assessed all singleton pregnant mothers who gave birth at Khalij-e-Fars Hospital in Bandar Abbas, Iran, between January 2020 and 2022. All preterm and post-term deliveries were excluded. Mothers were divided into two groups: late-term mothers (41 0/7-41 6/7 weeks of gestation) and term mothers (37 0/7-40 6/7 weeks of gestation). Demographic factors, obstetric factors, maternal comorbidities, and prenatal outcomes were extracted from the electronic data of each mother. The incidence of late-term births was calculated. The chi-squared test was used to compare differences between the groups. Logistic regression models were used to assess the association of prenatal outcome with late-term pregnancy. RESULTS: There were 8,888 singleton deliveries during the study period, and 1,269 preterm and post-term pregnancies were ruled out. Of the 7,619 deliveries, 309 (4.1%) were late-term, while 7,310 (95.9%) were term. There were no sociodemographic differences between term and late-term mothers. The late-term group had a higher prevalence of primiparous mothers, and the term group had a higher prevalence of diabetes. Late-term mothers had a higher risk of macrosomia (adjusted odds ratio (aOR): 2.24 (95% confidence interval (CI): 1.34-3.01)), meconium amniotic fluid (aOR: 2.32 (95% CI: 1.59-3.14)), and fetal distress (aOR: 2.38 (95% CI: 1.54-2.79)). When compared to term pregnancy, the risk of low birth weight (LBW) was lower in late-term pregnancy (aOR: 0.69 (95% CI: 0.36-0.81)). CONCLUSIONS: Late-term pregnancy was found to be more likely to be associated with macrosomia, meconium amniotic fluid, and fetal distress, but serious maternal and neonatal adverse events were comparable to term pregnancy.

Evaluation of Perinatal and Neonatal Outcomes of Syrian Refugees Compared to Turkish Population: A Snapshot During the COVID-19 Pandemic.

BACKGROUND: The perinatal and neonatal outcomes of Syrian refugees during the coronavirus disease 2019 (COVID-19) pandemic are unknown. Therefore, in this study, we aimed to evaluate these outcomes. METHODS: Turkish (n = 303) and Syrian refugees (n = 303) who delivered in our hospital between June 1, 2020 and December 31, 2020 were included in the study. Demographic, perinatal, and neonatal data were obtained by retrospectively evaluating hospital records. RESULTS: Adolescent pregnancy was more common in Syrian refugees (p < 0.001). The rates of antenatal visits, performed combined test, triple test, quadruple test, fetal anatomy ultrasound, and glucose tolerance test were lower in all refugees (p < 0.01). Furthermore, there was no difference in the mode of delivery, Hb after delivery, gestational age, birth weight, Apgar score, stillbirth, and fetal anomaly (p > 0.05 for all). CONCLUSION: Despite poorer antenatal care during the COVID-19 pandemic, Syrian refugee pregnant women had similar perinatal and neonatal outcomes compared with the Turkish pregnant population.

Neurodevelopmental Outcomes in Preterm Infants Receiving a Multicomponent vs. a Soybean-Based Lipid Emulsion: 24 Month Follow-Up of a Randomized Controlled Trial.

BACKGROUND: Few studies in the literature have analyzed the long-term neurodevelopmental outcomes of the administration of a multicomponent versus a soybean-based lipid emulsion (LE) in preterm infants receiving parenteral nutrition (PN). A recent randomized controlled trial conducted in our unit provided evidence of better growth in head circumference during the hospital stay in those who received a multicomponent LE. METHODS: This is a 24 month follow-up study of preterm infants, previously enrolled in a randomized trial, who received a multicomponent LE (SMOFlipid®) or a standard soybean-based one (Intralipid®). We evaluated neurodevelopmental outcomes at 24 months of corrected age (CA) in the two groups. RESULTS: Ninety-three children were followed up to the age of 24 months CA. Due to the peculiar time frame of the SARS-CoV-2 pandemic, neurodevelopmental outcomes were evaluated only in 77 children: 37 in the SMOFlipid® group and 40 in the Intralipid® group. No differences in major disability rates or in Griffith's evaluation were found between the two groups. CONCLUSIONS: In our population study, the administration of a multicomponent LE containing fish oil, compared to a soybean-based LE, had no significant effects on neurodevelopmental outcomes in preterm infants at 24 months CA.

Pregnancy Outcomes in SARS-CoV-2-Positive Patients: A 20-Month Retrospective Analysis of Delivery Cases.

Background and Objectives: The SARS-CoV-2 infection brings supplemental risks for pregnant women. Due to controversial hesitancy, their vaccination rate was lower in 2021 compared to the general population. In addition, access to maternal care was reduced during the pandemic. We conducted a retrospective cross-sectional analysis of the health records data over 20 months (1 April 2020 to 20 November 2021) aiming to explore the outcomes in SARS-CoV-2-positive cases referred for delivery to a tertiary public hospital in Western Romania. Materials and Methods: Women with SARS-CoV-2 infection diagnosed for the first time at the moment of birth who delivered singletons after 24 weeks of gestation, and had a clear immunization status were included in the analysis. Results: Out of the 97 patients included in the study, 35 (36%) had undergone ARN-based vaccination. Five cases of maternal death were recorded (all unvaccinated). Our retrospective exploratory analysis showed that the presence of COVID-19 symptoms in the SARS-CoV-2-positive patients made a significant impact on the delivery hospitalization, with a median hospital stay increase from 5 to 9 days (Mann-Whitney test, p = 0.014): longer hospitalization was recorded in the symptomatic cases irrespective of their vaccination status. No other adverse outcomes, such as gestational age at delivery, C-section rate, 5 min Apgar index, or birth weight were associated with the presence of symptoms. Conclusions: Our clinic maintained safe maternal care for the COVID-19 patients during the analyzed period. Vaccination of the expectant women was beneficial in SARS-CoV-2-positive patients by lowering the risk of COVID-19 symptoms, with subsequent implications on the newborns' health and maternal attachment.

The effects of preconception and early gestation SARS-CoV-2 infection on pregnancy outcomes and placental pathology.

OBJECTIVE: To evaluate if peri-pregnancy timing of a PCR+ test for SARS-CoV-2 RNA affects pregnancy outcomes and placental pathology. METHODS: This is a retrospective cohort study conducted in a tertiary center. Pregnancy outcomes and placental pathology were compiled for women who tested positive for SARS-CoV-2 RNA from a nasopharyngeal swab assessed by RT-PCR. The population comprised four groups that were PCR+ preconception (T0) or in the 1st (T1), 2nd (T2), or 3rd (T3) trimester of pregnancy. A fifth, control group (TC) tested PCR- for SARS-CoV-2 before delivery. RESULTS: Seventy-one pregnancies were studied. The T0 group exhibited lower gestational ages at delivery, had infants with the lowest birth weights, the highest rate of pregnancy loss before 20 weeks. Features of maternal vascular malperfusion and accelerated villous maturation were prominent findings in the histopathology of placentas from women PCR+ for SARS-CoV-2 RNA, especially in the T0 and the T1 groups. CONCLUSION: Women at highest risk for pregnancy complications are those who test PCR+ for viral RNA preconception or during first trimester of pregnancy.

A retrospective study of COVID during pregnancy and the outcome of vaginal delivery.

Introduction: SARS-CoV, MERS-CoV, and SARS-CoV-2, later named coronavirus disease 2019 (COVID-19), are three highly pathogenic and lethal human coronaviruses that have arisen in the last two decades. Pregnant women have a higher risk due to a special state of immunosuppression. However, there is no proof that pregnant women and their babies are more vulnerable to infection, as data is limited.The primary goal of this retrospective study is to examine the effects of early COVID-19 diagnosis and to address the best method of delivery based on medical records of neonatal and maternal outcomes observed at Nepal's Paropakar Maternity Hospital. This retrospective research will determine whether vaginal delivery is healthy compared to cesarean delivery and whether the outcome of a COVID-19 pregnancy in both mother and the baby is independent of the disease's status of the mother. Methods: Study design: The proposed study is a retrospective cross-sectional study. Patients population: 104 cases of COVID positive pregnancy with vaginal delivery or caesarean section. Results: The neonatal outcomes of COVID pregnancy revealed at least 51% baby born with Low APGAR score, 18% born prematurely, 19% with low birth weight, 7% requiring NICU admission, 3% Neonatal asphyxia, and 2% Neonatal death. Furthermore, when normal vaginal delivery and Cesarean section were compared there was no significant between the differences found in the outcomes. Conclusion: The COVID positive status had no association with the perinatal outcomes. Moreover, COVID status rarely affected the course of pregnancy. Guideline: STROCSS 2021.

Neonatal Outcome Associated With Maternal COVID-19 Infection in Adolescent Patients.

Background Coronavirus disease 2019 (COVID-19) infection during pregnancy has been associated with high rates of preeclampsia, stillbirth, and preterm birth. Adolescent pregnancy has also been associated with various adverse maternal and neonatal outcomes, including preeclampsia, stillbirth, preterm birth, congenital anomalies, and low birth weight. Therefore, this study aimed to determine whether COVID-19 infection associated with adolescent pregnancy represents an additional risk factor. Methods We performed a study that included 17 adolescent COVID-19- positive patients, who delivered in the Department of Obstetrics and Gynecology of University Emergency Hospital, Bucharest, between 01.04.2020 and 15.04.2022, and a control group of 17 patients who were COVID-19-negative and delivered in the same period in the same unit. In the control group, additional risk factors that could affect neonatal outcomes were excluded. The COVID-19 infection was confirmed using a polymerase chain reaction (PCR) test. The analysis of neonatal outcomes included preterm birth, low birth weight, stillbirth, congenital anomalies, and Apgar score calculated at one minute. Results The data from this study showed that COVID-19 infection does not influence the newborn's weight or Apgar score in adolescent patients. Also, in our study, COVID-19 infection was not statistically significant according to preterm delivery in adolescents. Conclusion Adolescent pregnancy represents an important health problem associated with a high risk of maternal and neonatal complications. However, COVID-19 infection does not influence neonatal outcomes in this population.

SARS-CoV-2 Infection and Pregnancy: Maternal and Neonatal Outcomes and Placental Pathology Correlations.

There is accumulating evidence on the perinatal aspects of COVID-19, but available data are still insufficient. The reports on perinatal aspects of COVID-19 have been published on a small group of patients. Vertical transmission has been noted. The SARS-CoV-2 genome can be detected in umbilical cord blood and at-term placenta, and the infants demonstrate elevated SARS-CoV-2-specific IgG and IgM antibody levels. In this work, the analysis of clinical characteristics of RT-PCR SARS-CoV-2-positive pregnant women and their infants, along with the placental pathology correlation results, including villous trophoblast immunoexpression status for SARS-CoV-2 antibody, is presented. RT-PCR SARS-CoV-2 amniotic fluid testing was performed. Neonatal surveillance of infection status comprised RT-PCR testing of a nasopharyngeal swab and the measuring of levels of anti-SARS-CoV-2 in blood serum. In the initial study group were 161 pregnant women with positive test results. From that group, women who delivered during the hospital stay were selected for further analysis. Clinical data, laboratory results, placental histomorphology results, and neonatal outcomes were compared in women with immunohistochemistry (IHC)-con SARS-CoV-2-positive and IHC SARS-CoV-2-negative placentas (26 cases). A positive placental immunoprofile was noted in 8% of cases (n = 2), whereas 92% of cases were negative (n = 24). Women with placental infection proven by IHC had significantly different pathological findings from those without. One infected neonate was noted (n = 1; 4%). Infection was confirmed in perinatal autopsy, as there was the intrauterine fetal demise. The potential course of the infection with the risk of vertical transmission and implications for fetal-neonatal condition is critical for proper clinical management, which will involve comprehensive, multidisciplinary perinatal care for SARS-CoV-2-positive patients.

Adherence to Mediterranean Diet and Its Association with Maternal and Newborn Outcomes.

BACKGROUND: Pregnancy is a crucial stage in a woman's life and can be affected by epigenetic and environmental factors. Diet also plays a key role in gestation. This study aimed to evaluate how a greater or lesser adherence to the Mediterranean Diet (MD) influences specific parameters of mother and newborn. METHODS: After delivery, the women participating in the study answered a questionnaire: demographic information; anthropometric data (pre-pregnancy weight, height, and gestational weight gain); dietary habits information (adherence to MD before and during pregnancy, using the validated Mediterranean Diet Adherence Screener (MEDAS), quality of protein intake); pregnancy information (onset of complications, cesarean/vaginal delivery, gestational age at birth, birth weight, birth length); and clinical practitioner for personalized dietary patterns during pregnancy. RESULTS: A total of 501 respondents have been included in the study, and 135 were excluded for complications. Women who followed the advice of clinical nutritionists showed better adherence to MD (p = 0.02), and the baby's birth weight was higher (p = 0.02). Significant differences in gestational weight gain (p < 0.01) between groups with dissimilar diet adherence were demonstrated. CONCLUSION: Our data demonstrate a significant relationship between adherence to MD and birthweight.

Clinical Manifestation and Obstetric Outcomes in Pregnant Women with SARS-CoV-2 Infection at Delivery: A Retrospective Cohort Analysis.

This retrospective cohort study aimed to analyze the clinical manifestations, complications, and maternal-fetal outcomes in patients affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during delivery. The cohort included 61 pregnant women positive for SARS-CoV-2 infection at the time of delivery. Patients were divided into two groups: symptomatic and asymptomatic. We found a significantly higher rate of leukocytosis (p < 0.00078) and lymphopenia (p < 0.0024) in symptomatic women compared with asymptomatic ones. Other laboratory parameters, such as CRP (p = 0.002), AST (p = 0.007), LDH (p = 0.0142), ferritin (p = 0.0036), and D-dimer (p = 0.00124), were also significantly more often increased in the group of symptomatic pregnant women. Overall, symptomatic pregnant women with SARS-CoV-2 infection at the delivery show more often altered laboratory parameters compared with asymptomatic ones; nevertheless, they have a slightly higher but non-significant rate of preterm delivery, cesarean section, as well as lower neonatal birth weight and Apgar score, compared with asymptomatic women.

Maternal and Neonatal Outcomes in Infected Pregnant Women with Coronavirus: A Systematic Review

Background & aim: Novel coronavirusease 2019 (Covid-19) started in China and caused unexplained pneumonia. The risk of adverse pregnancy outcomes increase in respiratory viral infection during pregnancy. This systematic review was performed to investigate the maternal and neonatal outcomes in pregnant women infected with Covid-19. Methods: In this systematic review, the international databases (PubMed, Cochrane Library, Web of Science, Scopus, Embase, PsycINFO, Google scholar) as well as national databases (SID and Magiran) were searched to find out the articles published from 1 September 2020 to 30 April 2021 regarding maternal and neonatal outcomes in pregnant women infected with Covid-19. Keywords were selected based on Mesh ("Pregnancy", "Gravidity", "Delivery", "Infant", "Newborn", "Neonate", "Outcome", "Complication", "Abortion", "Obstetric Labor, Premature", "Cesarean Section", "Fetal Death", "Infant, Premature", "Coronavirus Infection", "COVIDK19"). The full texts of articles were reviewed by two independent reviewers and the relevant data was extracted. Results: 20 studies including 78 pregnant women entered in this review. All women were at third trimester of pregnancy except 2 cases who were less than 28 weeks. The most prevalent clinical symptoms were fever, cough and sore throat. The most common maternal outcomes were intrauterine distress, rupture of membranes and preterm delivery. Most infants delivered by cesarean section. The most common neonatal complications were prematurity, small for gestational age, fetal distress, low birth weight and bacterial pneumonia. Conclusion: In this systematic review, we found some evidence to suggest that COVID-19 pneumonia causes negative maternal and neonatal outcomes in pregnant women infected with Covid-19. © 2021 Mashhad University of Medical Sciences.

Impact of SARS-CoV-2 infection during pregnancy and persistence of antibody response.

BACKGROUND: Pregnant women may be at an increased risk of developing severe or critical disease associated with the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection causing severities during pregnancy. We performed a prospective study to describe the impact of SARS-CoV-2 infection on pregnancy outcomes and on the newborn, depending on the severity of the disease. The antibody response and persistence of SARS-CoV-2 anti-Spike (S) IgG, IgA and anti-Nu- cleocapsid (NCP) IgG, was investigated. METHODS: A total of 48 pregnant women with SARS-CoV-2 infection were enrolled, and sequential serum samples from 30 of them were collected until one year after infection. Outcomes of pregnan- cy and newborn parameters were evaluated in comparison with 200 uninfected controls. RESULTS: Asymptomatic infection was observed in 31/48 women (64.5%), mild COVID-19 in 12/48 women (25.0%), while 5/48 women (10.5%) developed pneumonia. Women with pneumonia mount- ed significantly higher levels of anti-S IgG, IgA and anti-NCP IgG between 1 and 3 months after onset of infection compared to asymptomatic women. Anti-S IgG persisted in the majority of women from 6 months to at least one year after infection, especially in those with symptomatic infection and pneumonia, while anti-S IgA and anti-NCP IgG declined earlier. Pregnancy complications and new- born parameters were not significantly different from those observed in uninfected controls. CONCLUSION: Anti-SARS-CoV-2 antibody development and persistence was not impaired in pregnant women, while SARS-CoV-2 infection did not cause major pregnancy or newborn complications in asymptomatic or symptomatic women, nor in women with pneumonia receiving prompt clinical care.
