SARS-COV-2 Infection in Children and Young People in Bulgaria - A Prospective, Single-Center, Cohort Study

Compared to other respiratory viruses, the proportion of hospitalizations due to SARS-CoV-2 among children is relatively low. While severe illness is not common among children and young individuals, a particular type of severe condition called multisystem inflammatory syndrome in children (MIS-C) has been reported. The aim of this prospective cohort study, which followed a group of individuals under the age of 19, was to examine the characteristics of patients who had contracted SARS-CoV-2, including their coexisting medical conditions, clinical symptoms, laboratory findings, and outcomes. The study also aimed to investigate the features of children who met the WHO case definition of MIS-C, as well as those who required intensive care. A total of 270 patients were included between March 2020 and December 2021. The eligible criteria were individuals between 0-18 with a confirmed SARS-CoV-2 infection at the Infectious Disease Hospital "Prof. Ivan Kirov"in Sofia, Bulgaria. Nearly 76% of the patients were <= 12 years old. In our study, at least one comorbidity was reported in 28.1% of the cases, with obesity being the most common one (8.9%). Less than 5% of children were transferred to an intensive care unit. We observed a statistically significant difference in the age groups, with children between 5 and 12 years old having a higher likelihood of requiring intensive care compared to other age groups. The median values of PaO2 and SatO2 were higher among patients admitted to the standard ward, while the values of granulocytes and C-reactive protein were higher among those transferred to the intensive care unit. Additionally, we identified 26 children who met the WHO case definition for MIS-C. Our study data supports the evidence of milder COVID-19 in children and young individuals as compared to adults. Older age groups were associated with higher incidence of both MIS-C and ICU admissions.Copyright © 2023 P. Velikov et al., published by Sciendo.

Findings from the ECHO Cohorts Regarding the Effects of the COVID-19 Pandemic

Background: Studies suggest perinatal infection with SARSCoV- 2 can induce adverse birth outcomes, but studies published to date have substantial limitations. Most have identified cases based upon their presentation for clinical care, and very few have examined pandemic-related stress which may also impact adverse birth outcomes. Objective(s): To evaluate the relationships between SARSCoV- 2 infection in pregnancy and pandemic-related stress with birth outcomes. Study Design: We conducted an observational study of 211 mother-newborn dyads in three urban cohorts participating in the Environmental Influences on Child Health Outcomes (ECHO) Program. Serology for SARS-CoV-2 was assessed in a convenience sample of prenatal maternal, cord serum or dried blood spots from births occurring between January 2020-September 2021. Specimens were assessed for IgG, IgM, and IgA antibodies to nucleocapsid, S1 spike, S2 spike, and receptor-binding domain. A Pandemic-related Traumatic Stress (PTS) scale was based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition Acute Stress Disorder criteria. Result(s): 36% were positive for at least one antibody type, chiefly IgG. Self-report of infection was not significantly correlated with combined serology. There were no differences in gestational age (GA), birth weight, preterm birth (PTB), or low birth weight (LBW) among seropositive mothers. However, IgM seropositive mothers had children with lower BW (434g, 95% CI: 116- 752), BW Z score-for-GA (0.73 SD, 95% CI 0.10-1.36) and were more likely to deliver preterm (OR 8.75, 95% CI 1.22-62.4). Associations with LBW sustained in sensitivity analyses limited to pre-vaccine samples, and PTS symptoms were not associated with birth outcomes. The addition of PTS did not substantially change associations with BW, although associations with PTB attenuated to near-significance. Conclusion(s): We identified decreased birth weight and increased prematurity in mothers IgM seropositive to SARS-CoV-2, independent of PTS. Though there are limits to interpretation, the data support efforts to prevent SARS-CoV-2 infections in pregnancy.

Outcomes of symptomatic gallstone disease in pregnant women: A retrospective study

Gallstone disease with advanced symptoms is one of the common abdominal emergencies during pregnancy and it is considered to be one of the most frequently reported non-obstetric surgical conditions in pregnant women. This study aimed to evaluate the outcomes of surgical cholecystectomy in pregnant women with symptoms of advanced gallstones. This is a retrospective analysis of 2814 pregnant women who attended various wards in government and private hospitals in the governorates of Diyala and Kirkuk in Iraq for more than 2 years, between February 2020 and June 2022. The hospital database was used to confirm the diagnosis of advanced gallstone symptoms in these pregnant women. The incidence of symptomatic gallstones in pregnant women, diagnosis and method of therapeutic management, cholecystectomy according to the pregnancy periods, and perinatal complications of patients according to therapeutic methods were determined. The results confirmed that out of 2814 pregnancies, only 126 (4%) had symptoms of gallstones. It was found that the majority of cases 67 (53%) were within the first trimester of pregnancy and the least 29 (23%) was observed in the second trimester. Acute cholecystitis was the generality 84 (67%) diagnosed in pregnant women with symptomatic gallbladder disease and only 9 (7%) of the patients had undergone prenatal cholecystectomy versus 117 (93%) who were managed conservatively. A total of 20 (16%) cases with undesirable complications were recorded, where 12 cases with low birth weight were noted, where 4 of them underwent surgery and 8 were treated conservatively. It was concluded that a large proportion of women suffer from symptoms of gallstones during pregnancy. Most cases can be managed conservatively, and intervention should be performed as often as needed.Copyright © 2023, Codon Publications. All rights reserved.

Effect of Policies Aiming to Restrict Ultrasound Use

INTRODUCTION: During the early months of the COVID-19 pandemic, policies were implemented that sought to reduce in-person prenatal visits and ultrasounds. We sought to evaluate the effect of those policies on the rate of diagnosed fetal growth restriction and infant low birth weight. METHODS: We performed a cohort study of patients delivered at an academic center. Participants who received prenatal care during the time period of restricted visits were matched in a 1:1 ratio to patients receiving care during an equivalent time period when there were no such restrictions (group I: July 1, 2019, to December 31, 2019;and group II: March 23, 2020, to September 23, 2020). Medical records were reviewed for clinical and demographic characteristics. Neonatal morbidity was defined as any of the following: stillbirth, neonatal death, preterm birth, neonatal intensive care unit admission, low birth weight. Data were analyzed using chi-square and Mann-Whitney U test where appropriate. P <.05 was significant. RESULTS: Our cohort included 580 patients. Overall, the group had a 13% preterm birth rate, 8.2% were diagnosed with fetal growth restriction, and 26% had the composite neonatal morbidity. All patients in the cohort had at least one ultrasound. Compared to group I, group II had more individuals who had only one ultrasound during the pregnancy (3.1 versus 0%, P =.004), but overall the group had more total ultrasounds performed (1.5 [1–3] versus 1 [1–2], P =.02) and had more patients who required fetal surveillance for maternal and fetal conditions (56 versus 44, P =.014). Group II was more likely to have a neonatal demise (1.4 versus 0.3%, P <.01), but there was no difference in the rate of prenatal diagnosis of fetal growth restriction or low birth weight. CONCLUSION: Policies to reduce prenatal ultrasounds were not effective in reducing ultrasounds performed, and there was no difference in the diagnosis of fetal growth restriction despite an increase in comorbidity.

The Impact of Prenatal Maternal Mental Health during the COVID-19 Pandemic on Birth Outcomes: A Study within CONCEPTION Cohort

Background: External natural events, such as hurricanes, floods, and the COVID-19 pandemic can contribute to increased populational stress, especially for pregnant persons. Exposure to crises can produce short- and longterm health effects on pregnant persons and their offspring. There has been much interest in the association between maternal depression, anxiety, and stress during pregnancy and perinatal outcomes such as preterm birth (PTB) and low birth weight (LBW), before and since the COVID-19 pandemic, however results are controversial. Objective(s): Assess the association between prenatal mental health during the COVID-19 pandemic and preterm birth (delivery <37 weeks gestation) and low birthweight (<2,500 grams). Method(s): Pregnant individuals, >18 years, were recruited in Canada and provided data through a web-based questionnaire. We analyzed data on persons recruited between 06/2020-08/2021 who completed questionnaires while pregnant and two months post-partum. Data on maternal sociodemographics, comorbidities, medication use, mental health (Edinburgh Postnatal Depression Scale, General Anxiety Disorder-7, stress), pandemic hardship (CONCEPTION - Assessment of Stress from COVID-19), and on gestational age at delivery and birth weight, were selfreported. Crude and adjusted relative risks (aRR) with 95% confidence interval (95%CI) were calculated to quantify the association between PTB/LBW and maternal mental health. Result(s): A total of 1,265 and 1,233 participants were included in the analyses of PTB and LBW, respectively. No associations between PTB and prenatal mental health (depression [aRR 1.01, 95%CI 0.91-1.11], anxiety [aRR 1.04, 95%CI 0.93-1.17], stress [aRR 0.88, 95%CI 0.71-1.10], nor hardship [aRR 1.00, 95%CI 0.96-1.04]) after adjusting for potential confounders. The risk of PTB was increased with nonwhite ethnicity/race (aRR 3.85, 95%CI 1.35-11.00), consistently with the literature. Similar findings were observed for LBW (depression [aRR 1.03, 95%CI 0.96- 1.13], anxiety [aRR 1.05, 95%CI 0.95-1.17], COVID stress [aRR 0.92, 95%CI 0.77-1.09], or overall hardship [aRR 0.97, 95%CI 0.94-1.01]). Conclusion(s): No association was found between prenatal mental health nor hardship during the COVID-19 pandemic and the risk of PTB or LBW. However, it is imperative to continue the follow-up of mothers and their offspring to detect long-term health problems early.

Two major challenges for pregnancy: labor emergencies and SARS-CoV-2 infection - our experience in Saint John hospital, Bucharest, Romania

Introduction: Obstetric emergencies that occur during labor, often present as a major indication for prompt completion of labor by instrumental methods or emergency cesarean section. The purpose of this study was to present the clinical features of emergencies, the evolution of labor, maternal and fetal or neonatal complications at patients with SARS-COV-2 infection. Materials and methods: We performed a retrospective study that included 150 pregnant women who gave birth in Bucur Maternity, St John Hospital, Bucharest, between 2018-2020 that fulfilled the features of obstetrical emergency during labor and SARS-CoV-2 infection. The study group was divided in patients positive for SARS-CoV-2 and negative for SARS-CoV-2. Results: Following PCR testing for SARS-CoV-2 were 26.67% of patients positive and 73.33% had a negative result. Analyzing the data obtained from this group of patients, it resulted that the average hospitalization is higher in the positive group (7.05 days) versus the negative group (5.47 days). The average gestational age at birth of SARS-CoV-2 positive patients was 37.26 weeks, lower than the gestational age of neonates from uninfected mothers (38.41 weeks). The average of the APGAR scores in the COVID group is 8.41, and for the negative group is 8.90. Conclusions: The associated SARS-CoV-2 infection played a significant role in terms of the APGAR score and the early peripartum outcomes of new-borns, negatively influencing the value of the APGAR index. Gestational age was considerably lower in patients diagnosed with the infection. The SARS-CoV-2 virus infection has a significant influence in unsatisfactory neonatal outcomes compared to new-borns of healthy mothers.

Impact of Sars-Cov2 Infecion during Pregnancy on Maternal and Neonatal Outcomes

Purpose of Study: Pregnant women are at considerable risk for SARS-CoV-2 infection with adverse maternal and neonatal outcomes. Mother-to-child-transmission can occur, in-utero, perinatally or postnatally with significant complications in the newborn. Little is known on impact of SARS-CoV-2 on newborn infants. Our objectives were to describe maternal and neonatal outcomes among those with SARS-CoV-2 infection since beginning of the pandemic. Methods Used: This was a retrospective review of data from a single center with level III NICU from April 2020 through March 2022 in Los Angeles, CA. The study included pregnant women who were screened at delivery and/or during pregnancy and tested positive with PCR test. Data of these women and their infants were reviewed from medical records. Institutional IRB approval was obtained to review the data. Summary of Results: During the study period 152 mothers were SARs-CoV-2 positive in pregnancy or at delivery. Maternal risk factors included obesity (13.2%), pre-eclampsia (15.1%) and diabetes (19.7%). Fourteen (9.2%) were symptomatic for 0-7 days prior to delivery predominantly with cough, fever and myalgia. Majority (58.7%) delivered vaginally. SARS-CoV-2 exposed infants had a median gestational age of 38.3 weeks;35 (23%) were preterm. Median birthweight was 3120 grams and 32 infants 31 (20.5%) were low birthweight. Thirty-one (20.4%) infants needed resuscitation at delivery. Common symptoms for infants included respiratory symptoms (22.4%), hyperbilirubinemia (15.1%) and hypoglycemia (7.2%). Sixty-eight infants (44.7%) required admission to NICU. Majority of the infants (130) had PCR tests at 24 hours and 48 hours if still hospitalized. Five (3.8%) were PCR+: 4 at 24 hours and 1 at 48 hours. Another 5 infants had positive PCR for SARS-CoV-2 in infancy. Conclusion(s): SARS-CoV-2 infection was present at delivery in a significant number of pregnant women with 3.8 % of their infants. Although a majority of women were asymptomatic at the time of delivery, there was significant morbidity among women with pre-eclampsia and diabetes. Newborn morbidity included prematurity, low birth weight and respiratory distress even in PCR- newborns. These data emphasize the need for screening all pregnant women for SARS-CoV-2 at delivery, and close monitoring of mother-infant dyad if infected. Vaccination of pregnant women should be encouraged.

COVID-19 mitigation measures increase preterm birth and low birth weight in the public healthcare system in Uruguay.

OBJECTIVE: To evaluate the impact of the COVID-19 pandemic on preterm birth (PB) and low birth weight (LBW), comparing public and private healthcare systems of the National Integrated Health System in Uruguay, where the mitigation measures for the COVID-19 pandemic generated an immediate socioeconomic and psychological crisis, which caused a sharp widening of existing socioeconomic inequalities. METHODS: A national observational study was conducted comparing perinatal outcomes in the first 6 months of 2020 (period of the pandemic without pregnancy infections), which was the beginning of the pandemic, with the same period of the previous year 2019 (pre-pandemic period with no mitigation measures) among pregnant women from the public and private health systems. Data were retrieved from the national database (Informatic Perinatal System) and analyzed by healthcare system category. RESULTS: A total of 36 559 deliveries were assessed: 18 563 in the 2019 study period and 17 996 in the 2020 study period. In the public system, there was a significant increase in the risk of LBW (adjusted relative risk [aRR] 1.12, 95% confidence interval [CI] 1.05-1.36) and of the composite outcome (PB or LBW) (aRR 1.15, 95% CI 1.04-1.26). In the private system, by contrast, there was a non-statistically significant decrease of LBW and there were no changes in the incidence of PB and the composite outcome in 2020. CONCLUSION: The different evolution of birth outcomes in the public and private systems suggests an unequal impact of mitigation measures on populations of different socioeconomic levels. Given that no COVID-19 infections were identified in pregnant women during the study period, this research offers an opportunity to differentiate the biologic effects of the virus from the psychological and social impacts derived from containment measures.

Changing Trends of Pregnancy Related Acute Kidney Injury - a Single Centre Prospective Observational Study from Southern India

Introduction: Pregnancy-related acute kidney injury (PR-AKI) in India is largely showing a declining trend due to improved and accessible obstetric care. Nevertheless, PR-AKI continues to cause significant maternal and fetal morbidity and mortality. This study was taken up with the intention to study the incidence and clinical spectrum of AKI in pregnancy in recent times and assess maternal and neonatal outcomes Methods: All pregnant women admitted in the Department of Obstetrics and Gynecology at St John's Medical College Hospital, Bengaluru between January 2018 to June 2020 were screened for AKI with the following criteria 1. Increase in serum creatinine to >0.8mg/dL and/or a sudden increase in serum creatinine by more than 50% when prior renal function was normal. 2. Oligo-anuria 3. Need for renal replacement therapy Women with preexisting CKD were excluded. Patient's clinical and laboratory details recorded. Dialysis support was provided if indicated. The clinical profile and renal outcome of the mother and fetal outcome was assessed at the time of discharge. Mothers' were also followed up at the end of 3 months of postpartum period. Recovery was categorized as Complete recovery- normal serum creatinine (<0.8 mg/dL) or a previously known baseline and no proteinuria /hypertension at the end of 3 months Partial recovery- renal function improved but serum creatinine did not return to normal range and patient was dialysis independent. No recovery- patient continued to require dialysis at the end of 3months. Result(s): Of the 2650 deliveries in the study period 42 women (Mean age 26.9 +/-3.6 years) were diagnosed AKI during pregnancy (1.58%). Baseline characteristics and outcomes are depicted in table 1. Majority of women (n=37) were referred from peripheral hospitals. Hypertension and decreased fetal movements were the common reasons for referral. Third trimester was the most common time of presentation (76.1%). Severe Preeclampsia and HELLP syndrome was the leading cause of AKI (59.5%).ATN secondary to obstetric complications, sepsis and hemolytic uremic syndrome were the other causes. One case each of cortical necrosis, acute fatty liver of pregnancy and COVID 19 associated AKI was seen. Mean duration of hospital stay was 12.1+/-6.9 days. More than one third patients' required ICU stay (35.7%).12 patients (28.5%) required renal replacement therapy. Of them, 3 were dialysis dependent at the end of 3 months and 4 had partial renal recovery. 3 patients expired during hospital stay. Fetal survival was 69.04%.13 babies' required NICU care (44.8%). Neonatal outcomes are summarized in table 2. Close to one third of the pregnancies with AKI were associated with intrauterine fetal demise (28.5%). Low birth weight and prematurity were the common reasons for NICU admission with mean NICU stay of 8.2 +/-2.3 days [Formula presented] [Formula presented] Conclusion(s): Severe preeclampsia was the most common cause of AKI in our study. PR-AKI continues to be a significant problem in the peripheries of developing countries where availability of health care facilities is meager, with late referral to tertiary care centers. One third of the patients required ICU stay & dialytic support. Women who required dialysis had poorer renal prognosis. There was 30% fetal loss seen in PR-AKI and also a higher incidence of low birth weight and prematurity. No conflict of interestCopyright © 2023

Covid-19 and Pregnancy: Epidemiology, Clinical Features, Maternal and Perinatal Outcomes. A Systematic Review

Background and objectives: COVID-19 pandemic had quite a significant impact on a number of obstetric outcomes. This is often directly attributed to complications of COVID-19. This article is a systematically review literature on the epidemiology, clinical features, maternal and perinatal outcomes of COVID-19 in pregnancy. Materials and methods. A PRISMA methodology search was conducted on the databases of PubMed, Scopus, Medline, Google Scholar, Web of Science and Central BMJ using MeSH keywords or combinations of the words"COVID-19", "SARS-CoV-2", "pregnancy", "epidemiology", "comorbid disease", "pregnancy and childbirth outcome", "preeclampsia", "fetus". Only articles published between December 1, 2019 to February 28, 2022 were considered. After preliminary analysis of more than 600 publications, 21 articles were short-listed for final processing. The studies were selected using a Newcastle-Ottawa scale style questionnaire. The clinical features, risk factors, co-morbid conditions, maternal and neonatal outcomes were presented in two separate tables respectively. Results. COVID-19 incidence in pregnancy ranged from 4.9% to 10.0%. Such women were 5.4 times more likely to be hospitalized and 1.5 times more to need ICU care. Dyspnoea and hyperthermia were associated with a high risk of severe maternal (OR 2.56;95% CI 1.92-3.40) and neonatal complications (OR 4.97;95% CI 2.11-11.69). One in ten of neonates had a small weight for gestational age (9.27 +/- 3.18%) and one in three required intensive care unit observation. Conclusions. Despite the increasingly emerging evidence on the associations between pregnancy and COVID-19 infection, the data is sometimes contradictory necessitating further studies.Copyright © 2022 Trylyst.

COVID-19 exposure during pregnancy and low birth weight in community development blocks, Purba Bardhaman: A retrospective cohort study.

Introduction: COVID-19 exposure during pregnancy is hypothesized to affect the birth weight of the children. Community based findings on such hypothesis are scarce in West Bengal. This study was conducted with the objective to determine the relationship between low birth weight (LBW) and maternal exposure to COVID-19. Materials and Methods: In this retrospective cohort study, mothers of children, who were born between February 2020 and October 2021 and who were registered in the subcenters of Purba Barddhaman district, West Bengal, were selected as study population. Mothers who were diagnosed as COVID-19 positive during the antenatal period were considered as 'Pregnancy with COVID' and others were considered as 'Pregnancy without COVID'. The minimum required sample size using Fleiss formula were 119 and 476, respectively, whose were selected through multi-stage random sampling. A schedule was used to collect data through review of relevant records of antenatal registers of sub-centers of selected individuals. The association was checked through multivariate logistic regression model where P < 0.05 was considered statistically significant. Results: Incidence of LBW in COVID pregnancy, Non-COVID Pregnancy group were 30.3% and 18.7%, respectively. COVID positivity during pregnancy shows relative risk of 1.62 and attributable risk of 38.28% for LBW baby as pregnancy outcome. Multivariate analysis reveals that LBW babies are significantly associated with COVID status during pregnancy (AOR 2.18, 1.3-3.63) after adjusting for anemia in pregnancy, incomplete antenatal visits, mothers age ≥30 years, parity and periods of gestation. Conclusion: The study concludes that COVID positivity during pregnancy significantly increases the risk of LBW as pregnancy outcome.

An Overview About Pediatric Type 1 Diabetes Mellitus

Background: Diabetes mellitus (DM) represents one of the most common metabolic diseases in the world, with rising prevalence in recent decades. Most cases are generally classified into two major pathophysiological categories: type 1 diabetes mellitus (DM1), which progresses with absolute insulin deficiency and can be identified by genetic and pancreatic islet autoimmunity markers, and type 2 diabetes mellitus (DM2), which is the most prevalent form and involves a combination of resistance to the action of insulin with an insufficient compensatory response of insulin secretion. In the last two decades, in parallel with the increase in childhood obesity, there has also been an increase in the incidence of DM2 in young people in some populations. Other forms of diabetes may affect children and adolescents, such as monogenic diabetes (neonatal diabetes, MODY – maturity onset diabetes of the young, mitochondrial diabetes, and lipoatrophic diabetes), diabetes secondary to other pancreatic diseases, endocrinopathies, infections and cytotoxic drugs, and diabetes related to certain genetic syndromes, which may involve different treatments and prognoses. DM1 is considered an immuno-mediated disease that develops as a result of gradual destruction of insulin-producing pancreatic beta cells that eventually results in their total loss and complete dependence on exogenous insulin. Clinical presentation can occur at any age, but most patients will be diagnosed before the age of 30 years

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.

No significant changes in preterm birth, low-birth-weight, and small-for-gestational-age infants during the first year of the COVID-19 pandemic in a rural area in Japan.

AIMS: To evaluate the coronavirus disease 2019 pandemic's impact on pregnancy outcomes in a Japanese rural area. METHODS: This retrospective study focused on the periods between March 1, 2020, and February 28, 2021 (during the coronavirus disease 2019 pandemic), and January 1, 2017, and December 31, 2019. Singleton pregnancies delivered at or after 22 gestational weeks were included. Preterm delivery, low-birth-weight, and small-for-gestational-age infant rates during the pandemic were compared to those in the preceding 3 years. RESULTS: In the pandemic and control groups, 1650 and 5762 pregnant women were included, respectively. Two pregnant women with coronavirus disease 2019 were identified (0.1%). There were no significant intergroup differences in preterm delivery rates (control, 4% vs. pandemic, 3.3%; difference: -0.7% [95% confidence interval: -1.7%-0.3%], p = 0.22). The low-birth-weight rate tended to decrease; however, the difference was insignificant (7.9% vs. 6.5%; difference: -1.4% [95% confidence interval: -2.8-0%], p = 0.06). The small-for-gestational-age infant rate was significantly lower in the pandemic than in the control group (7.3% vs. 5.2%; difference: -2.1% [95% confidence interval: -3.3-0.8%], p < 0.01). However, the interrupted time series analysis showed no significant trend. CONCLUSIONS: There were no significant changes in the rates of preterm delivery, low-birth-weight infants, and small-for-gestational-age infants during the pandemic's first year compared to those in the preceding 3 years. Behavioral changes, such as "stay-at-home" measures, may not improve pregnancy outcomes in Japan.

Are preterm birth and very low birth weight rates altered in the early COVID (2020) SARS-CoV-2 era?

Objective: We evaluated the prevalence of preterm birth (PTB) and very low birth weight (VLBW) during Jan-Dec 2,020 (early COVID era) at 5 hospitals (2 in West Virginia, 3 in California) compared to Jan 2017-Dec 2019 (pre-COVID) inclusive of 2 regional perinatal centers (1 in Huntington, WV and 1 in San Jose, CA) and 3 community hospitals (1 each in Cabell, Los Angeles and Santa Clara counties). Design/methods: We examined PTB and VLBW rates of live births at 5 US hospitals from Jan 2017-Dec 2020. We compared PTB and VLBW rates in 2020 to 2017-2019 using Poisson regression and rate ratio with a 95% confidence interval. We stratified live births by gestational age (GA) (<37, 33-36, and <33 weeks) and birth weight (≤1,500 g, >1,001 g to ≤1,500 g, ≤1,000 g). We examined PTB rates at 4 of the hospitals during Jan-Dec 2020 and compared them to the prior period of Jan 2017-Dec 2019 using Statistical Process Control (SPC) for quarterly data. Results: We examined PTB and VLBW rates in 34,599 consecutive live births born Jan 2017-Dec 2019 to rates of 9,691 consecutive live births in 2020. There was no significant change in PTB (<37 weeks GA) rate, 10.6% in 2017-2019 vs. 11.0% in 2020 (p = 0.222). Additionally, there was no significant change when comparing VLBW rates in 2017-2019 to 2020, 1.4% in 2017-2019 vs. 1.5% in 2020 (p = 0.832). Conclusion: We found no significant change in the rates of PTB or VLBW when combining the live birth data of 5 US hospitals in 3 different counties.

Evaluation of the effects of COVID-19 disease and the trimester in which the disease is diagnosed on obstetric and neonatal outcomes: A retrospective cohort study.

AIM: To evaluate the effects of COVID-19 disease and the trimester in which the disease is diagnosed on obstetric and neonatal outcomes. METHODS: This retrospective cohort study was conducted with 358 patients who had or had not been diagnosed with COVID-19 during their pregnancy, had a miscarriage or had given birth. RESULTS: COVID-19 disease during pregnancy was associated with higher maternal hypertensive disease, preterm birth, low birth weight, low first- and fifth-minute Apgar scores, and need for neonatal intensive care unit. The incidence of preterm birth, low birth weight, low first- and fifth-minute Apgar scores, and need for neonatal intensive care unit in those diagnosed with COVID-19 in the second trimester was significantly higher than those diagnosed with COVID-19 in other trimesters. The frequency of cesarean section was observed most in those diagnosed with COVID-19 in the 3rd trimester, while it was observed in those diagnosed with COVID-19 at least in the first trimester. CONCLUSION: The presence of COVID-19 during pregnancy may be associated with an increased risk of iatrogenic preterm birth. The frequency of preterm birth in pregnant women diagnosed with COVID-19 in the second trimester is higher than in pregnant women diagnosed with COVID-19 in other trimesters. As the pregnancy trimester at the time of diagnosis progresses, the frequency of cesarean section increases. While the risk of maternal hypertensive disease increases more in pregnant women with COVID-19, the effect of the trimester in which COVID-19 was passed on the risk of maternal hypertensive disease is not observed.

Childbirth and puerperium during the COVID-19 pandemic: patient experience and frequency of prematurity / Parto y puerperio durante la pandemia por COVID-19: experiencia de las pacientes y frecuencia de prematuridad

Objetivo: Evaluar la percepción de las madres que tuvieron su parto durante la pandemia COVID en relación a la obligación de no recibir visitas en su puerperio, y cuantificar la frecuencia de prematuridad que otros centros del mundo mostraron que se redujo durante la pandemia. Método: Estudio observacional retrospectivo con encuestas realizadas entre el 1 de septiembre y el 31 diciembre 2020, y análisis de estadísticas locales de la Unidad de Maternidad y Neonatología. Resultados: Sobre el 90% de las madres que contestaron la encuesta afirmó haber descansado mejor y preferir un retorno a las visitas con horarios reducidos. La frecuencia de prematuridad se redujo significativamente en nuestra institución (8,08% entre 2014 y 2019 vs. 1,6% en 2020). Conclusiones: La mayoría de las puérperas prefiere un horario reducido para visitas en el posparto. Este hallazgo y la caída en la frecuencia de prematuridad obligan a reflexionar sobre nuestro cuidado prenatal actual.

Objective: To evaluate the perception of mothers who gave birth during the COVID pandemic in relation to the obligation not to receive visits during the puerperium, and to quantify the frequency of prematurity that other centers in the world showed decreased during the pandemic. Method: Retrospective observational study with surveys conducted between September 1st and December 31, 2020, and analysis of local statistics from the Maternity and Neonatal Unit. Results: Over 90% of the mothers who answered the survey stated that they had rested better and preferred a return to visits with reduced hours. The frequency of prematurity was signficantly reduced in our institution ((8.08% between 2014 and 2019 vs 1.6% in 2020). Conclusions: Most postpartum women prefer a reduced schedule for pospartum visits. This finding and the drop in the frequency of prematurity force us to reflect on our current prenatal care.

Examining the Remote Learning Experiences of Children Born Very Preterm During the COVID-19 Pandemic

This study examined the remote learning activities children born very preterm (VPT;gestational age <= 30 weeks) received, compared with children born full term (FT;gestational age >= 37 weeks), during the COVID-19 pandemic. Parents of 5- to 6-year-olds born VPT (n = 33) and FT (n = 33) reported on the provision, frequency, and duration of teacher-provided live instruction, educational materials, and homework;and parent-provided educational materials. More kindergarten children born VPT received small group instruction and fewer received large group instruction than FT children. Preschoolers born VPT engaged in parent-provided learning apps, educational videos, and reading activities less frequently or for shorter durations than FT children. Findings suggest that while teachers generally implemented remote learning similarly for children born VPT and FT, parents did not. Children born VPT are at higher risk for educational problems and may benefit from more intensive school- and home-based educational interventions to help offset the impact of school closures.
