A Case Report of Neonatal 2019 Coronavirus Disease in China

Perinatal Maternal-Fetal/Neonatal Transmission of COVID-19: A Guide to Safe Maternal and Neonatal Care in the Era of COVID-19 and Physical Distancing

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease 2019 (COVID-19), is highly contagious and can cause serious respiratory illness and other clinical manifestations. The aim of this review is to summarize the clinical presentation, diagnosis, and outcomes of COVID-19 in pregnant women and neonates, who may be especially vulnerable to the effects of COVID-19, and to discuss what is known about potential maternal-fetal and maternal-neonatal transmission of SARS-CoV-2.

Confirming Vertical Fetal Infection With Coronavirus Disease 2019: Neonatal and Pathology Criteria for Early Onset and Transplacental Transmission of Severe Acute Respiratory Syndrome Coronavirus 2 From Infected Pregnant Mothers

Increasing numbers of pregnant women with coronavirus disease 2019 are being reported around the world. The majority of neonates delivered to pregnant women infected with severe acute respiratory syndrome coronavirus 2 have been negative for the virus, but a small number have tested positive for infection. It is important to determine whether vertical transmission of coronavirus disease 2019 occurs and the mechanisms for its development. Based on a number of clinical and laboratory findings, it has been suggested that transplacental transmission may be occurring, but a method to confirm this is necessary. This communication analyzes and evaluates the covariables that have been discussed as potential indicators of vertical and, specifically, intrauterine transmission, including the timing of onset of neonatal illness, neonatal viral test positivity, neonatal antibody testing for immunoglobulin (Ig) G and IgM, and viral analysis of swabs of whole specimens of placental tissue. None of these methods can provide confirmatory evidence that infection developed prior to labor and delivery, or that transplacental transmission occurred. This commentary proposes that diagnosis of early-onset neonatal coronavirus disease 2019 infection should be limited to neonates with positive reverse transcription polymerase chain reaction testing for severe acute respiratory syndrome coronavirus 2 within the initial 72 hours of life. It also proposes that the occurrence of intrauterine transplacental severe acute respiratory syndrome coronavirus 2 among infected mother-infant dyads be based upon identification of severe acute respiratory syndrome coronavirus 2 in chorionic villus cells using immunohistochemistry or nucleic acid methods such as in situ hybridization. Evaluating placentas from neonates with coronavirus disease 2019 using these methods will be instrumental in determining the potential role and prevalence of transplacental transmission of the coronavirus.

A neonatal cluster of novel coronavirus disease 2019: clinical management and considerations

BACKGROUND

Lately, one of the major clinical and public health issues has been represented by Coronavirus disease of 2019 (COVID-19) during pregnancy and the risk of transmission of the infection from mother to child. Debate on perinatal management and postnatal care is still ongoing, principally questioning the option of the joint management of mother and child after birth and the safety of breastfeeding. According to the available reports, neonatal COVID-19 appears to have a horizontal transmission and seems to be paucisymptomatic or asymptomatic, compared to older age groups. The aim of this work is to describe a cluster of neonatal COVID-19 and discuss our experience, with reference to current evidence on postnatal care and perinatal management.

METHODS

This is a retrospective observational case series of five mother-child dyads, who attended the Labor and Delivery Unit of a first-level hospital in Italy, in March 2020. Descriptive statistics for continuous variables consisted of number of observations, mean and the range of the minimum and maximum values.

RESULTS

Five women and four neonates tested positive for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). In one case, the mother-child dyad was separated and the neonate remained negative on two consecutive tests. Two positive neonates developed symptoms, with a predominant involvement of the gastrointestinal tract. Blood tests were unremarkable, except for a single patient who developed mild neutropenia. No complications occurred.

CONCLUSIONS

We agree that the decision on whether or not to separate a positive/suspected mother from her child should be made on an individual basis, taking into account the parent's will, clinical condition, hospital logistics and the local epidemiological situation. In conformity with literature, in our study, affected neonates were asymptomatic or paucisymptomatic. Despite these reassuring findings, a few cases of severe presentation in the neonatal population have been reported. Therefore, we agree on encouraging clinicians to monitor the neonates with a suspected or confirmed infection.

Healthy neonate born to a SARS-CoV-2 infected woman: A case report and review of literature

BACKGROUND

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly discovered coronavirus that has generated a worldwide outbreak of infections. Many people with coronavirus disease-2019 (COVID-19) have developed severe illness, and a significant number have died. However, little is known regarding infection by the novel virus in pregnant women. We herein present a case of COVID-19 confirmed in a woman delivering a neonate who was negative for SARS-CoV-2 and related it to a review of the literature on pregnant women and human coronavirus infections.

CASE SUMMARY

The patient was a 36-year-old pregnant woman in her third trimester who had developed progressive clinical symptoms when she was confirmed as infected with SARS-CoV-2. Given the potential risks for both the pregnant woman and the fetus, an emergency cesarean section was performed, and the baby and his mother were separately quarantined and cared for. As a result, the baby currently shows no signs of SARS-CoV-2 infection (his lower respiratory tract samples were negative for the virus), while the mother completely recovered from COVID-19.

CONCLUSION

Although we presented a single case, the successful result is of great significance for pregnant women with SARS-CoV-2 infection and with respect to fully understanding novel coronavirus pneumonia.

What Pediatric Dentists Need to Know about Coronavirus Disease (COVID-19)

COVID-19, a viral disease fatal yet preventable is caused by a newly identified β-corona virus. The people most vulnerable to this infection are the ones with a prior history of diseases, low immunity, or either too old or too young (particularly children and infants). In the context of the virus's impact on the pediatric age groups, this article highlights some of the challenges and guidelines on managing it. Pediatric groups, like everyone else, are highly vulnerable to the infection by COVID-19. The lower number of pediatric patients involved at the beginning of a pandemic does not necessarily mean that children are less vulnerable to the infection. However, the good news is that the disease usually has a mild course and appropriate prevention and oral health management in children can help to keep it at bay. Adherence to simple compliance and safety protocols can go a long way. For instance, in the course of some of the procedures performed by a pediatric dentist, there may be a risk of aerosols being generated, which in turn can lead to cross-infection making the patient vulnerable to contracting COVID-19. In such a situation, parents are advised to take good home-based care and take telemedicine consultation immediately. This article lays a concrete emphasis on reviewing the limited published literature that is specific to the pediatric population regarding epidemiology, pathogenesis, diagnosis, and treatment modalities of COVID-19. It analyzes the potential risk from COVID-19 associated with pediatric dental treatment. In addition, it presents a series of considerations on potential oral prevention strategies on the management of urgent and non-urgent dental procedures in a context of disease transference control. This literature review also gives an insight for the private practitioner to have healthier management in the pediatric fraternity during this highly contagious COVID-19 pandemic.

Congenital SARS-CoV-2 Infection in a Neonate With Severe Acute Respiratory Syndrome

Coronavirus disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is mainly transmitted through droplets, but other ways of transmission have been hypothesized. We report a case of vertical transmission of SARS-CoV-2 in a preterm born to an infected mother, confirmed by the presence of the virus in the neonatal blood, nasopharyngeal and oropharyngeal swabs collected in the first half an hour of life. The neonate presented with acute respiratory distress, similar to the findings in severely affected adults. This case highlights the importance of pregnancy, labor and neonatal period surveillance of affected mothers and their newborns.

Perioperative management of patients with suspected or confirmed COVID-19: review and recommendations for perioperative management from a retrospective cohort study

BACKGROUND

Current guidelines for perioperative management of coronavirus disease 19 (COVID-19) are mainly based on extrapolated evidence or expert opinion. We aimed to systematically investigate how COVID-19 affects perioperative management and clinical outcomes, to develop evidence-based guidelines.

METHODS

First, we conducted a rapid literature review in EMBASE, MEDLINE, PubMed, Scopus, and Web of Science (January 1 to July 1, 2020), using a predefined protocol. Second, we performed a retrospective cohort analysis of 166 women undergoing Caesarean section at Tongji Hospital, Wuhan during the COVID-19 pandemic. Demographic, imaging, laboratory, and clinical data were obtained from electronic medical records.

RESULTS

The review identified 26 studies, mainly case reports/series. One large cohort reported greater mortality in elective surgery patients diagnosed after, rather than before surgery. Higher 30 day mortality was associated with emergency surgery, major surgery, poorer preoperative condition and surgery for malignancy. Regional anaesthesia was favoured in most studies and personal protective equipment (PPE) was generally used by healthcare workers (HCWs), but its use was poorly described for patients. In the retrospective cohort study, duration of surgery, oxygen therapy and hospital stay were longer in suspected or confirmed patients than negative patients, but there were no differences in neonatal outcomes. None of the 262 participating HCWs was infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) when using level 3 PPE perioperatively.

CONCLUSIONS

When COVID-19 is suspected, testing should be considered before non-urgent surgery. Until further evidence is available, HCWs should use level 3 PPE perioperatively for suspected or confirmed patients, but research is needed on its timing and specifications. Further research must examine longer-term outcomes.

The Direct and Indirect Impact of SARS-CoV-2 Infections on Neonates: A Series of 26 Cases in Bangladesh

BACKGROUND

The impact of SARS-CoV-2 on neonates remains largely unknown in low- and middle-income countries (LMICs). We provide an epidemiologic and clinical report of SARS-CoV-2 infections in neonates hospitalized in Bangladesh.

METHODS

Outborn neonates admitted to Dhaka Shishu Hospital, a tertiary-care referral hospital, between 29 March and 1 July were screened for SARS-CoV-2. We reviewed clinical data, including chest radiograph and laboratory reports, and conducted SARS-CoV-2 genome sequencing. Patients were followed-up for 27-75 days. A subset of caregivers was also tested.

RESULTS

Of 83 neonates tested, 26 were positive (median age 8 days). Most neonates were admitted with diagnosis unrelated to SARS-CoV-2: 11 presented with serious non-communicable diseases, 7 with early-onset sepsis, 5 with late-onset sepsis and 2 with pneumonia. In 3 of 5 chest radiograph, infiltrates and ground-glass or patchy opacities were noted. Two neonates developed metabolic acidosis, one developed disseminated intravascular coagulation. Most SARS-CoV-2 positive neonates were referred to government-designated COVID-19 hospitals, leading to gaps in treatment. Twenty-three neonates could be followed-up: 12 were healthy, 8 died and 3 were still seeking medical care. Of 9 caregivers tested, 8 were positive.

CONCLUSIONS

SARS-CoV-2 may have serious adverse effects on children born in LMICs. The virus likely contributed directly to two deaths, but the remaining 6 neonates who died had serious comorbidities. Positive SARS-CoV-2 test results led to gaps in immediate clinical care for other morbidities, which likely contributed to adverse outcomes. This case series emphasizes the need to understand COVID-19 in neonates in LMICs and its indirect impacts.

Coronavirus global pandemic: An overview of current findings among pediatric patients

BACKGROUND

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic has been emerged as a cardinal public health problem. Children have their own specific clinical features; notably, they seem to be escaping the severe respiratory adverse effects. The international scientific community is rapidly carrying out studies, driving to the need to reassess knowledge of the disease and therapeutic strategies.

AIM

To assess the characteristics of COVID-19 infected children worldwide of all ages, from neonates to children and adolescents, and how they differ from their adult counterparts.

SEARCH STRATEGY

An electronic search in PubMed was conducted, using combinations of the following keywords: coronavirus, SARS-CoV-2, COVID-19, children. The search included all types of articles written in English between January 1, 2019 until August 15, 2020.

RESULTS

The search identified 266 relevant articles. Children were mainly within family clusters of cases and have relatively milder clinical presentation compared with adults; children were reported to have better outcomes with a significantly lower mortality rate. Cough and fever were the most common symptoms while pneumonia was the cardinal respiratory manifestation of infected children. Laboratory results and thoracic imaging give varying results.

CONCLUSIONS

Children were mainly family cluster cases and usually presented with a mild infection, although cases presented with the multisystem inflammatory syndrome are becoming more apparent. Studies determining why the manifestations of SARS-CoV-2 infection are so variable may help to gain a better understanding of the disease and accelerate the development of vaccines and therapies.

Perinatal COVID-19 outcomes: evaluating the strength of current evidence

Purpose of the Study: Viral respiratory diseases, like those caused by novel strains of influenza and Coronaviridae, have historically disproportionately affected pregnant women and conferred increased risk of adverse perinatal outcomes. Initial reports published from Wuhan, China identified only limited symptoms in pregnant women and no cases of mortality, but more recent reports from other regions of the world have reported contrasting information. The purpose of the study was to evaluate initially published cases of SARS-CoV-2 infection in pregnant women in China and compare them to subsequently published studies from the remainder of the world. Materials and Methods: This review curates 199 maternal published cases of SARS-CoV-2 infection and COVID-19 initially reported in the literature from China and contrasts them to more recent literature reporting clinical findings and outcomes of 729 selected cases from the rest of the world, including the United States. Results: Overall, initial case reports and series from China reported no cases of maternal mortality, which contrasts with subsequent reports from other regions of the world demonstrating significant morbidity and mortality can and does occur in pregnant women infected with SARS-CoV-2. Conclusion: While initial reports suggest limited risks of infection in pregnancy with SARS-CoV-2, subsequent findings have demonstrated pregnant women are at risk for severe morbidity and mortality. Case studies and series that are imperative in the early stages of a pandemic to provide data on a novel pathogen cannot be used to provide generalizable information predicting group risks.

COVID-19 in pregnancy: the foetal perspective-a systematic review

OBJECTIVE

We aimed to conduct a systematic review of the available literature to determine the effects of confirmed cases of COVID-19 in pregnant women from the foetal perspective by estimation of mother to child transmission, perinatal outcome and possible teratogenicity.

METHODS

Data sources: eligible studies between 1 November 2019 and 10 August 2020 were retrieved from PubMed, Embase, LitCovid, Google Scholar, EBSCO MEDLINE, CENTRAL, CINAHL, MedRXiv, BioRXiv and Scopus collection databases. English language case reports, case series and cohort studies of SARS-CoV-2 confirmed pregnant women with data on perinatal outcome, congenital anomalies and mother to child transmission were analysed.

RESULTS

38 case reports, 34 cohort and case series describing 1408 neonates were included for evidence acquisition of mother to child transmission. 29 case reports and 31 case series and cohort studies describing 1318 foetuses were included for the evaluation of perinatal outcome and congenital anomalies. A pooled proportion of 3.67% neonates had positive SARS-CoV-2 viral RNA nasopharyngeal swab results and 7.1% had positive cord blood samples. 11.7% of the placenta, 6.8% of amniotic fluid, 9.6% of faecal and rectal swabs and none of the urine samples were positive. The rate of preterm labour was 26.4% (OR=1.45, 95% CI 1.03 to 2.03 with p=0.03) and caesarean delivery (CS) was 59.9% (OR=1.54, 95% CI 1.17 to 2.03 with p=0.002). The most common neonatal symptom was breathing difficulty (1.79%). Stillbirth rate was 9.9 per 1000 total births in babies born to COVID-19 mothers.

CONCLUSION

Chances of mother to child transmission of the SARS-CoV-2 virus is low. The perinatal outcome for the foetus is favourable. There is increased chances of CS but not preterm delivery. The stillbirth and neonatal death rates are low. There are no reported congenital anomalies in babies born to SARS CoV-2 positive mothers.

Maternal Coronavirus Infections and Neonates Born to Mothers with SARS-CoV-2: A Systematic Review

The coronavirus disease 2019 (COVID-19) pandemic is continuously affecting the lives of all people. Understanding the impact of COVID-19 on pregnancy in terms of morbidity, mortality, and perinatal maternal and fetal outcomes is essential to propose strategies for prevention and infection control. Here, we conducted a systematic review to investigate pregnant women infected with COVID-19 in terms of signs and symptoms, type of delivery, comorbidities, maternal and neonatal outcomes, and the possibility of vertical transmission. A search on Embase and PubMed databases was performed on 31 October 2020. Observational studies and case reports on pregnant women infected with COVID-19 were included without language restrictions. The 70 selected studies included a total of 1457 pregnant women diagnosed with COVID-19 in the first, second, and third trimesters of pregnancy. The most common signs and symptoms were fever, cough, and nausea. The most frequent comorbidities were obesity, hypertensive disorders, and gestational diabetes. Among maternal and fetal outcomes, premature birth (n = 64), maternal death (n = 15), intrauterine fetal death or neonatal death (n = 16), cases of intrauterine fetal distress (n = 28), miscarriage (n = 7), decreased fetal movements (n = 19), and severe neonatal asphyxia (n = 5) were the most frequent. Thirty-nine newborns tested positive for SARS-CoV-2. Additionally, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA was detected in the placenta (n = 13) and breast milk (n = 6). This review indicates that COVID-19 during pregnancy can result in maternal, fetal, and neonatal complications. In addition, SARS-CoV-2 viral exposure of neonates during pregnancy and delivery cannot be ruled out. Thus, we highlight the need for long-term follow-up of newborns from mothers diagnosed with COVID-19 to establish the full implications of SARS-CoV-2 infection in these children.

CD71+ Erythroid Cells in Human Neonates Exhibit Immunosuppressive Properties and Compromise Immune Response Against Systemic Infection in Neonatal Mice

Newborns are highly susceptible to infectious diseases. The underlying mechanism of neonatal infection susceptibility has generally been related to their under-developed immune system. Nevertheless, this notion has recently been challenged by the discovery of the physiological abundance of immunosuppressive erythroid precursors CD71⁺ erythroid cells (CECs) in newborn mice and human cord blood. Here, as proof of concept, we show that these cells are also abundant in the peripheral blood of human newborns. Although their frequency appears to be more variable compared to their counterparts in mice, they rapidly decline by 4 weeks of age. However, their proportion remains significantly higher in infants up to six months of age compared to older infants. We found CD45 expressing CECs, as erythroid progenitors, were the prominent source of reactive oxygen species (ROS) production in both humans and mice. Interestingly, a higher proportion of CD45⁺CECs was observed in the spleen versus bone marrow of neonatal mice, which was associated with a higher ROS production by splenic CECs compared to their siblings in the bone marrow. CECs from human newborns suppressed cytokine production by CD14 monocytes and T cells, which was partially abrogated by apocynin in vitro. Moreover, the depletion of CECs in neonatal mice increased the number of activated effector immune cells in their spleen and liver, which rendered them more resistant to Listeria monocytogenes infection. This was evident by a significant reduction in the bacteria load in the spleen, liver and brain of treated-mice compared to the control group, which enhanced their survival rate. Our finding highlights the immunoregulatory processes mediated by CECs in newborns. Thus, such tightly regulated immune system in newborns/infants may explain one potential mechanism for the asymptomatic or mild COVID-19 infection in this population.

Challenges in Urology during the COVID-19 Pandemic

The COVID-19 pandemic has caused a global health threat. This disease has brought about huge changes in the priorities of medical and surgical procedures. This short review article summarizes several test methods for COVID-19 that are currently being used or under development. This paper also introduces the corresponding changes in the diagnosis and treatment of urological diseases during the COVID-19 pandemic. We further discuss the potential impacts of the pandemic on urology, including the outpatient setting, clinical work, teaching, and research.

Pregnancy and Breastfeeding During COVID-19 Pandemic: A Systematic Review of Published Pregnancy Cases

Background: The COVID-19 pandemic is an emerging concern regarding the potential adverse effects during pregnancy. This study reviews knowledge on the impact of COVID-19 on pregnancy and describes the outcome of published cases of pregnant women diagnosed with COVID-19. Methods: Searches were conducted in PubMed®, Scopus®, Web of Science®, and MedRxiv® up to 26th June 2020, using PRISMA standards, to identify original published studies describing pregnant women at any gestational age diagnosed COVID-19. There were no date or language restrictions on the search. All identified studies were included irrespective of assumptions on study quality. Results: We identified 161 original studies reporting 3,985 cases of pregnant women with COVID-19 (1,007 discharged while pregnant). The 2,059 published cases with pregnancy outcomes resulted in 42 abortions, 21 stillbirths, and 2,015 live births. Preterm birth occurred in 23% of cases. Around 6% of pregnant women required admission to an intensive care unit and 28 died. There were 10 neonatal deaths. From the 163 cases with amniotic fluid, placenta, and/or cord blood analyzed for the SARS-CoV-2 virus, 10 were positive. Sixty-one newborns were positive for SARS-CoV-2. Four breast milk samples from 92 cases showed evidence of SARS-CoV-2. Conclusion: Emerging evidence suggests that vertical transmission is possible, however, there is still a limited number of reported cases with intrapartum samples. Information, counseling and adequate monitoring are essential to prevent and manage adverse effects of SARS-CoV-2 infection during pregnancy.

Pregnancy and Childbirth in the COVID-19 Era-The Course of Disease and Maternal-Fetal Transmission

From the beginning of the Coronavirus Disease 2019 (COVID-19) pandemic, special attention has been paid to pregnant women and to monitoring comorbidities, such as gestational diabetes and hypertension, which could increase their risk of disease and death. The purpose of this review is to synthesize the available knowledge on the course of COVID-19 in pregnant women as well as the risk of maternal-fetal transmission. The study indicated that the course of COVID-19 is worse in pregnant women who are more often admitted to intensive care units or who require mechanical ventilation than nonpregnant women with COVID-19. Some symptoms, such as dyspnea and cough, were similar to those observed in nonpregnant women, but fever, headache, muscle aches, chills, and diarrhea were less frequent. A study revealed that premature delivery and cesarean section were more common in pregnant women diagnosed with COVID-19. In addition, recent studies confirm the possibility of intrauterine maternal-fetal transmission by positive genetic tests and the presence of IgM in newborns just after delivery; at the moment, the probability of transmission through mother's milk is inconclusive. Considering all the above, a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection is an important factor that threatens the health and life of both the mother and the fetus, but further studies are still needed.

Congenital, Intrapartum and Postnatal Maternal-Fetal-Neonatal SARS-CoV-2 Infections: A Narrative Review

BACKGROUND

There is inconclusive evidence regarding congenital, intrapartum, and postnatal maternal-fetal-neonatal SARS-CoV-2 infections during the COVID-19 pandemic. A narrative review was conducted with the aim of guiding clinicians on the management of pregnant women with respect to congenital, intrapartum, and postnatal maternal-fetal-neonatal SARS-CoV-2 infections and breastfeeding during the COVID-19 pandemic.

METHODS

Searches were conducted in Web of Science, PubMed, Scopus, Dialnet, CUIDEN, Scielo, and Virtual Health Library to identify observational, case series, case reports, and randomized controlled trial studies assessing the transmission of SARS-CoV-2 from mother to baby and/or through breastfeeding during the COVID-19 pandemic.

RESULTS

A total of 49 studies was included in this review, comprising 329 pregnant women and 331 neonates (two pregnant women delivered twins). The studies were performed in China (n = 26), USA (n = 7), Italy (n = 3), Iran (n = 2), Switzerland (n = 1), Spain (n = 1), Turkey (n = 1), Australia (n = 1), India (n = 1), Germany (n = 1), France (n = 1), Canada (n = 1), Honduras (n = 1), Brazil (n = 1), and Peru (n = 1). Samples from amniotic fluid, umbilical cord blood, placenta, cervical secretion, and breastmilk were collected and analyzed. A total of 15 placental swabs gave positive results for SARS-CoV-2 ribonucleic acid (RNA) on the fetal side of the placenta. SARS-CoV-2 RNA was found in seven breastmilk samples. One umbilical cord sample was positive for SARS-CoV-2. One amniotic fluid sample tested positive for SARS-CoV-2.

CONCLUSIONS

This study presents some evidence to support the potential of congenital, intrapartum, and postnatal maternal-fetal-neonatal SARS-CoV-2 infections during the COVID-19 pandemic. Mothers should follow recommendations including wearing a facemask and hand washing before and after breastfeeding.

Clinical characteristics of confirmed COVID-19 in newborns: a systematic review

OBJECTIVE

Aim of this systematic review is to investigate the available evidence describing neonatal outcomes in newborns who have SARS-CoV-2 infection in order to guide prevention of COVID-19 in newborns.

METHODS

This is the study protocol for a systematic review. MEDLINE, Web of Science, PubMed, Science Direct, CINAHL, Scopus, Cochrane, TUBİTAK databases, and key words of "Newborn" (neonatal OR clinical characteristics newborn OR infants less than 1 month OR infants less than 28 weeks OR Neonate) AND "clinical presentation" (epidemiology OR symptoms OR clinical course OR features) AND "COVID-19" (Coronavirus OR COVID-19 OR Sars-Cov2 OR coronavirus disease 2019 OR Novel Coronavirus OR 2019-nCoV) were searched for this systematic review. Randomized controlled trial, cross-sectional, case-control, and case reports, case reports examining neonatal outcomes in newborns who have SARS-CoV-2 infection were included. Studies were selected according to criteria around the population, intervention, comparator, outcome(s) of interest, and study design (PICOS framework). All citations and full-text articles were searched by independent five authors. The population that newborns with COVID-19 that confirmed within 28 d of birth are included. The interventions included in COVID-19 infection diagnosed via reverse transcription-polymerase chain reaction (RT-PCR) or serological. The primary outcomes were Neonatal clinical outcomes. The methodological quality of the studies was appraised using appropriate tools. Strength of the body of evidence was assessed according to the quality assessment tool for quantitative studies (QATQS).

RESULTS

The electronic search identified 1051 records that were examined, after evaluating 35 of them were included in the study. Seven studies were research articles and twenty-eight were case reports. Methodological quality was medium. Most of the clinical characteristics of newborns were respiratory difficulty and secondly fever. Some newborns gastrointestinal (GIS) symptoms in the form of diarrhea and feeding intolerance and abdominal distension were present in 50%. The fatality case did not exist in any newborn due to COVID-19. Death occurred in one case due to prematurity.

CONCLUSIONS

The most common symptoms in patients with COVID-19 infection in the neonatal period are respiratory tract symptoms and fever. It has been observed that the COVID-19 infection detected in the neonatal period is not fatal. However, data including more cases are needed.

Possible Vertical Transmission of COVID-19 to the Newborn; a Case Report

Vertical transmission of the novel coronavirus 2019 (COVID-19), has been reported in case reports and series, while the data regarding its transmission is still not enough. Thus, presenting different experiences form various regions could help better understand the virus behavior in pregnancy. We herein report a possible vertical transmission of COVID-19 from a mother to the neonate. A 41-year-old mother with signs and symptoms of acute respiratory illness presented with labor pain and vaginal leak at 37 weeks of gestation. She tested positive for COVID-19 using RT-PCR and underwent emergency cesarean section delivery and gave birth to a girl neonate. The baby tested positive for the COVID-19. Although vertical transmission of COVID-19 has not been proved yet, but there are several lines of evidences suggesting it. Paying close attention to the mother and newborn with COVID-19 and long-term follow-up are needed for better understanding of the virus in pregnancy.

Clinical presentations, laboratory and radiological findings, and treatments for 11,028 COVID-19 patients: a systematic review and meta-analysis

This systematic review and meta-analysis investigated the comorbidities, symptoms, clinical characteristics and treatment of COVID-19 patients. Epidemiological studies published in 2020 (from January-March) on the clinical presentation, laboratory findings and treatments of COVID-19 patients were identified from PubMed/MEDLINE and Embase databases. Studies published in English by 27th March, 2020 with original data were included. Primary outcomes included comorbidities of COVID-19 patients, their symptoms presented on hospital admission, laboratory results, radiological outcomes, and pharmacological and in-patient treatments. 76 studies were included in this meta-analysis, accounting for a total of 11,028 COVID-19 patients in multiple countries. A random-effects model was used to aggregate estimates across eligible studies and produce meta-analytic estimates. The most common comorbidities were hypertension (18.1%, 95% CI 15.4-20.8%). The most frequently identified symptoms were fever (72.4%, 95% CI 67.2-77.7%) and cough (55.5%, 95% CI 50.7-60.3%). For pharmacological treatment, 63.9% (95% CI 52.5-75.3%), 62.4% (95% CI 47.9-76.8%) and 29.7% (95% CI 21.8-37.6%) of patients were given antibiotics, antiviral, and corticosteroid, respectively. Notably, 62.6% (95% CI 39.9-85.4%) and 20.2% (95% CI 14.6-25.9%) of in-patients received oxygen therapy and non-invasive mechanical ventilation, respectively. This meta-analysis informed healthcare providers about the timely status of characteristics and treatments of COVID-19 patients across different countries.PROSPERO Registration Number: CRD42020176589.

Guidelines for Pregnancy Management During the COVID-19 Pandemic: A Public Health Conundrum

Pregnant women seem to be at risk for developing complications from COVID-19. Given the limited knowledge about the impact of COVID-19 on pregnancy, management guidelines are fundamental. Our aim was to examine the obstetrics guidelines released from December 2019 to April 2020 to compare their recommendations and to assess how useful they could be to maternal health workers. We reviewed 11 guidelines on obstetrics management, assessing four domains: (1) timeliness: the time between the declaration of pandemics by WHO and a guideline release and update; (2) accessibility: the readiness to access a guideline by searching it on a common browser; (3) completeness: the amount of foundational topics covered; and (4) consistency: the agreement among different guidelines. In terms of timeliness, the Royal College of Obstetricians and Gynaecologists (RCOG) was the first organization to release their recommendation. Only four guidelines were accessible with one click, while only 6/11 guidelines covered more than 80% of the 30 foundational topics we identified. For consistency, the study highlights the existence of 10 points of conflict among the recommendations. The present research revealed a lack of uniformity and consistency, resulting in potentially challenging decisions for healthcare providers.

COVID-19 during Pregnancy and Postpartum

Coronavirus Disease 2019 (COVID-19) triggered by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection has been declared a pandemic by the World Health Organization (WHO) on March 11, 2020. Oxidative stress and its related metabolic syndromes are potential risk factors in the susceptibility to, and severity of COVID-19. In concert with the earliest reports of COVID-19, obstetricians started to diagnose and treat SARS-CoV-2 infections during pregnancy ("COVID-19-Pregnancy"). High metabolic demand to sustain normal fetal development increases the burden of oxidative stress in pregnancy. Intracellular redox changes intertwined with acute phase responses at the maternal-fetal interface could amplify during pregnancy. Interestingly, mother-to-fetus transmission of SARS-CoV-2 has not been detected in most of the COVID-19-Pregnancy cases. This relative absence of vertical transmission may be related to the presence of lactoferrin in the placenta, amniotic fluid, and lacteal secretions. However, the cytokine-storm induced during COVID-19-Pregnancy may cause severe inflammatory damage to the fetus, and if uncontrolled, may later result in autism spectrum-like disorders and brain development abnormalities in neonates. Considering this serious health threat to child growth and development, the prevention of COVID-19 during pregnancy should be considered a high priority. This review summarizes the intricate virulence factors of COVID-19 and elucidate its pathobiological spectrum during pregnancy and postpartum periods with a focus on the putative and complex roles of endogenous and exogenous lactoferrin in conferring immunological advantage to the host.

The Effects of COVID-19 Pandemic on Pregnant Women: Perceived Stress, Social Support and Sleep Quality

Background

This cross-sectional study aims to identify the relationship between perceived stress, social support and sleep quality and the effects of the COVID-19 pandemic on pregnant women's perceived stress, social support and sleep quality.

Methods

The target population of the study was pregnant women who applied to the Family Health Center. After the sample calculation was performed, the study involved 166 participants. The data, which were quantitative in nature, were collected through a web-based, online questionnaire administered within a determined period. Data collection tools included the Multidimensional Scale of Perceived Social Support (MSPSS), the Perceived Stress Scale (PSS), and the Pittsburgh Sleep Quality Index (PSQI).

Results

Of all the participating pregnant women, 88% reported to have poor sleep quality during the COVID-19 pandemic. A moderate, negative relationship was found between the Pittsburgh Sleep Quality Index and the Multidimensional Scale of Perceived Social Support and a weak, positive relationship with the Perceived Stress Scale. While statistically significant differences were found between the pregnant women's perceived stress according to their psychological perceptions and perceptions about daily life (P < 0.05), no significant differences were found between the perceived social support level and sleep quality index.

Conclusion

It was considered that pregnant women's perceived social support levels, sleep quality, and perceived stress levels were affected during the COVID-19 pandemic.

Transmission of SARS-CoV-2: an update of current literature

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiologic agent for the 2019 coronavirus disease (COVID-19) pandemic, has caused a public health emergency. The need for additional research in viral pathogenesis is essential as the number of cases and deaths rise. Understanding the virus and its ability to cause disease has been the main focus of current literature; however, there is much unknown. Studies have revealed new findings related to the full transmission potential of SARS-CoV-2 and its subsequent ability to cause infection by different means. The virus is hypothesized to be of increased virulence compared with previous coronavirus that caused epidemics, in part due to its overall structural integrity and resilience to inactivation. To date, many studies have discussed that the rationale behind its transmission potential is that viral RNA has unexpectedly been detected in multiple bodily fluids, with some samples having remained positive for extended periods of time. Additionally, the receptor by which the virus gains cellular entry, ACE2, has been found to be expressed in different human body systems, thereby potentiating its infection in those locations. In this evidence-based comprehensive review, we discuss various potential routes of transmission of SARS-CoV-2-respiratory/droplet, indirect, fecal-oral, vertical, sexual, and ocular. Understanding these different routes is important as they pertain to clinical practice, especially in taking preventative measures to mitigate the spread of SARS-CoV-2.

A case report of newborn infant with severe COVID-19 in Mexico: Detection of SARS-CoV-2 in human breast milk and stool

Although COVID-19 in pregnant women and their neonates has been demonstrated, there is not enough evidence about how this vertical transmission occurs. This report describes a SARS-CoV-2 infection in a 21-year-old mother-daughter duo at the time of birth, focusing on the viral RNA detection in the stool of both and the human breast milk.

Care of the COVID-19 exposed complex newborn infant

As we confront COVID-19, the global public health emergency of our times, new knowledge is emerging that, combined with information from prior epidemics, can provide insights on how to manage this threat in specific patient populations. Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS), both caused by coronaviruses, caused serious respiratory illness in pregnant women that resulted in adverse perinatal outcomes. Thus far, COVID-19 appears to follow a mild course in the vast majority of pregnant women. A significant proportion of pregnant women appear to be asymptomatic carriers of SARS-CoV-2. However, there is limited information on how COVID-19 impacts the fetus and whether vertical transmission occurs. While these knowledge gaps are addressed, it is important to recognize the highly efficient transmission characteristics of SARS-C0V-2 and its potential for causing serious disease in vulnerable individuals, including health care workers. This review provides perspectives from a single center in New York City, the epicenter of the pandemic within the United States. It offers an overview of the preparations required for deliveries of newborns of mothers with COVID-19 and the management of neonates with particular emphasis on those born with complex issues.

A study of breastfeeding practices, SARS-CoV-2 and its antibodies in the breast milk of mothers confirmed with COVID-19

BACKGROUND

The possibility of 2019 novel coronavirus disease (COVID-19) transmission to neonates through breast milk remains unverified.

METHODS

This paper presents the interim results of a longitudinal study being carried out in Hubei province. As of 1 April 2020, 24 mothers confirmed with COVID-19, 19 mothers suspected with COVID-19 but Polymerase chain reaction negative, and 21 mothers without COVID-19 and their neonates have been recruited. Telephone follow-up was conducted to collect information on breastfeeding practices. Forty-four breast milk samples were collected from 16 of the 24 mothers with confirmed COVID-19 for the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) ribonucleic acid (RNA) and antibodies (IgM and IgG) testing.

FINDINGS

The average mother-child separation time was 36•7 ± 21•1 days among mothers confirmed with COVID-19, significantly longer than that of the suspected group (16•6 ± 13•1 days) and control group (10•5 ± 8•2 days). Both the COVID-19 confirmed (58•3%) and suspected (52•6%) groups presented significantly lower rates of breastfeeding as compared with the control group (95•2%). All 44 breast milk samples tested negative for the SARS-CoV-2 nucleic acid. Thirty-eight breast milk samples underwent antibody testing and all tested negative for IgG. Twenty-one breast milk samples from 8 women tested positive for IgM, while the remaining samples from 11 women tested negative.

INTERPRETATION

Considering the lack of evidence for SARS-CoV-2 transmission through breast milk, breastfeeding counselling along with appropriate hand hygiene precautions and facemasks should be provided to all pregnant women.

FUNDING

The study was funded by the Hong Kong Committee for UNICEF.

COVID-19 pandemic's effects on the quality of pregnant women's emergency treatment: Review of two cases from a medical center in northern Taiwan

The spread of COVID-19 has resulted in a high risk of infection in hospitals worldwide. The medical staff in emergency rooms, in particular, have borne the brunt of the pandemic, and strict protection measures are needed to avoid infection in these units. Taiwan as a whole has performed extremely well in this epidemic, an achievement that has been acknowledged internationally. This success can be attributed to the Taiwan Epidemic Prevention Management Center's extensive experience and courageous strategy. The emergency department professionals of all hospitals, in conjunction with the outstanding performance of the center's policy, have also done much to control the infection's spread. However, excessive protection can also negatively affect patients' safety and the quality of medical care, especially for pregnant and parturient women. This article uses two actual cases from a medical center in northern Taiwan to discuss the impact of COVID-19 on pregnant women. This case study serves to highlight that, to ensure more effective coordination during severe epidemics, a comprehensive infection prevention plan should be formulated. In addition, pregnant women's human rights must be safeguarded so that various protective mechanisms can be effectively used to achieve win-win solutions. Hospitals need to plan their production methods and timing in advance for when pregnant patients are in critical condition. The findings include that obstetricians recommend caesarean sections as a safer method in during epidemics. Emergency room physicians and obstetricians should also actively assist mothers prepare for birth to enhance maternal and fetal safety.

COVID-19 during pregnancy: non-reassuring fetal heart rate, placental pathology and coagulopathy

We report a case of a pregnant woman with COVID-19 who developed coagulopathy in the absence of severe clinical symptoms. A polymerase chain reaction test of a vaginal swab was positive for SARS-CoV-2 RNA, suggesting a possibility of perinatal transmission. Cesarean delivery was performed because of a non-reassuring fetal heart rate; the placenta showed increased perivillous fibrin deposition and intervillositis. Moreover, placental infection with SARS-CoV-2 was demonstrated by placental immunostaining. The findings suggest a possible relationship between placental fibrin deposition and chronic and acute intervillositis, non-reassuring fetal heart rate and coagulopathy in pregnant women with COVID-19. © 2020 The Authors.

Review of guidelines and recommendations from 17 countries highlights the challenges that clinicians face caring for neonates born to mothers with COVID-19

AIM

This review examined how applicable national and regional clinical practice guidelines and recommendations for managing neonates born to mothers with COVID-19 mothers were to the evolving pandemic.

METHODS

A systematic search and review identified 20 guidelines and recommendations that had been published by May 25, 2020. We analysed documents from 17 countries: Australia, Brazil, Canada, China, France, India, Italy, Japan, Saudi Arabia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, the UK and the United States.

RESULTS

The documents were based on expert consensus with limited evidence and were of variable, low methodological rigour. Most did not provide recommendations for delivery methods or managing symptomatic infants. None provided recommendations for post-discharge assimilation of potentially infected infants into the community. The majority encouraged keeping mothers and infants together, subject to infection control measures, but one-third recommended separation. Although breastfeeding or using breastmilk was widely encouraged, two countries specifically prohibited this.

CONCLUSION

The guidelines and recommendations for managing infants affected by COVID-19 were of low, variable quality and may be unsustainable. It is important that transmission risks are not increased when new information is incorporated into clinical recommendations. Practice guidelines should emphasise the extent of uncertainty and clearly define gaps in the evidence.

Breastfeeding in COVID-19: A Pragmatic Approach

The novel coronavirus disease 2019 (COVID-19) pandemic has resulted in changes to perinatal and neonatal care, concentrating on minimizing risks of transmission to the newborn and health care staff while ensuring medical care is not compromised for both mother and infant. Current recommendations on infant care and feeding when mother has COVID-19 ranges from mother-infant separation and avoidance of human milk feeding, to initiation of early skin-to-skin contact and direct breastfeeding. Health care providers fearing risks of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) maternal-infant transmission may veer toward restricted breastfeeding practices. We reviewed guidelines and published literature and propose three options for infant feeding depending on various scenarios. Option A involves direct breastfeeding with the infant being cared for by the mother or caregiver. In option B, the infant is cared for by another caregiver and receives mother's expressed milk. In the third option, the infant is not breastfed directly and does not receive mother's expressed milk. We recommend joint decision making by parents and the health care team. This decision is also flexible as situation changes. We also provide a framework for counseling mothers on these options using a visual aid and a corresponding structured training program for health care providers. Future research questions are also proposed. We conclude that evidence and knowledge about COVID-19 and breastfeeding are still evolving. Our options can provide a quick and flexible reference guide that can be adapted to local needs. KEY POINTS: · SARS-CoV-2 is unlikely transmitted via human milk.. · A shared decision making on infant feeding is the preferred approach.. · Mothers can safely breastfeed with appropriate infection control measures..

Infection prevention and control for labor and delivery, well baby nurseries, and neonatal intensive care units

During the early months of the COVID-19 pandemic, infection prevention and control (IP&C) for women in labor and mothers and newborns during delivery and receiving post-partum care was quite challenging for staff, patients, and support persons due to a relative lack of evidence-based practices, high rates of community transmission, and shortages of personal protective equipment (PPE). We present our IP&C policies and procedures for the obstetrical population developed from mid-March to mid-May 2020 when New York City served as the epicenter of the pandemic in the U.S. For patients, we describe screening for COVID-19, testing for SARS-CoV-2, and clearing patients from COVID-19 precautions. For staff, we address self-monitoring for symptoms, PPE in different clinical scenarios, and reducing staff exposures to SARS-CoV-2. For visitors/support persons, we address limiting them in labor and delivery, the postpartum units, and the NICU to promote staff and patient safety. We describe management of SARS-CoV-2-positive mothers and their newborns in both the well-baby nursery and in the neonatal ICU. Notably, in the well-baby nursery we do not separate SARS-CoV-2-positive mothers from their newborns, but emphasize maternal mask use and social distancing by placing newborns in isolates and asking mothers to remain 6 feet away unless feeding or changing their newborn. We also encourage direct breastfeeding and do not advocate early bathing. Newborns of SARS-CoV-2-positive mothers are considered persons under investigation (PUIs) until 14 days of life, the duration of the incubation period for SARS-CoV-2. We share two models of community-based care for PUI neonates. Finally, we provide our strategies for enhancing communication and education during the early months of the pandemic.

Imaging Findings of SARS-CoV-2 Infection in Pediatrics: A Systematic Review of Coronavirus Disease 2019 (COVID-19) in 850 Patients

RATIONALE AND OBJECTIVES

Children with COVID-19 seem to have a relatively milder disease and better prognosis; however, severe disease or death could still occur in this age group. Although the knowledge on the clinical and epidemiology of COVID-19 in pediatric patients is being accumulated rapidly, relevant comprehensive review on its radiological manifestations is still lacking. The present article reviews the radiological characteristics of COVID-19 in pediatrics, based on the previous studies.

MATERIALS AND METHODS

We conducted a systematic literature search for published articles by using Medline, Scopus, Google Scholar and Embase online databases. All studies describing CT findings of COVID-19 in pediatrics (<18years) were included.

RESULTS

A total of 39 studies with 850 pediatric patients were reviewed. 225 (26.5%) of patients had normal CT findings. Ground-glass opacities and consolidations were the most common CT abnormalities (384/625, 61.5%). Other findings were halo sign, interstitial opacities, bronchial wall thickening, and crazy-paving sign. Approximately 55% of patients had unilateral pulmonary findings. Most studies found peripheral and lower-lobe distribution to be a prominent imaging finding.

CONCLUSION

Our study showed that imaging findings in children were often milder and more focal than adults, typically as ground-glass opacities and consolidations with unilateral lower-lobe predominance, which have been regressed during the recovery time. A balance must be struck between the risk of radiation and the need for chest CT. If still necessary, low-dose CT is more appropriate in this age group. Albeit, due to the limited number of reported pediatrics with COVID-19, and the lack of consistency in CT descriptors, further work is still needed in this regard.

Lessons from past epidemics and pandemics and a way forward for pregnant women, midwives and nurses during COVID-19 and beyond: A meta-synthesis

OBJECTIVE

To consolidate qualitative research studies that examined the experiences and needs of pregnant women, midwives, and nurses of maternity units to provide a way forward for future research and practices during the current pandemic and future epidemics and pandemics.

DESIGN

Qualitative systematic review and meta-synthesis.

DATA SOURCE

Four electronic databases-PubMed, Scopus, PsycINFO, and Cumulative Index to Nursing and Allied Health (CINAHL).

REVIEW METHODS

Qualitative studies with samples of pregnant women, midwives, and/or nurses of maternity units who experienced epidemics and/or pandemics were searched from 1 January 2000 to 4 April 2020. The included studies were critically appraised using the ten-item Critical Appraisal Skills Programme (CASP) tool.

FINDINGS

Eight studies were included in this review. Four themes emerged from the synthesis: (1) psychological responses, (2) challenges faced, (3) coping strategies, and (4) sources of support and support needs.

KEY CONCLUSIONS

Pregnant women, midwives, and nurses experienced negative psychological responses during epidemics and pandemics. Challenges, such as limited available information and public stigma, were faced. Various coping strategies, such as actively looking for more information and seeking solace in religions, were practiced by pregnant women, midwives, and nurses. Families were both sources of support and stress and they expressed needs for more informational, emotional, and financial support during pandemics.

IMPLICATIONS FOR PRACTICE

More culturally diverse research in the future that includes the development of technology-based programs, trained community volunteer-led programs, psychosocial interventions, and anti-stigma and awareness initiatives are needed to combat the current pandemic and future public health crises.

Neonates With Complex Cardiac Malformation and Congenital Diaphragmatic Hernia Born to SARS-CoV-2 Positive Women-A Single Center Experience

BACKGROUND

Our understanding of the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on pregnancies and perinatal outcomes is limited. The clinical course of neonates born to women who acquired coronavirus disease 2019 (COVID-19) during their pregnancy has been previously described. However, the course of neonates born with complex congenital malformations during the COVID-19 pandemic is not known.

METHODS

We report a case series of seven neonates with congenital heart and lung malformations born to women who tested positive for SARS-CoV-2 during their pregnancy at a single academic medical center in New York City.

RESULTS

Six infants had congenital heart disease and one was diagnosed with congenital diaphragmatic hernia. In all seven infants, the clinical course was as expected for the congenital lesion. None of the seven exhibited symptoms generally associated with COVID-19. None of the infants in our case series tested positive by nasopharyngeal test for SARS-CoV-2 at 24 hours of life and at multiple points during their hospital course.

CONCLUSIONS

In this case series, maternal infection with SARS-CoV-2 during pregnancy did not result in adverse outcomes in neonates with complex heart or lung malformations. Neither vertical nor horizontal transmission of SARS-CoV-2 was noted.

Effect of pre-existing diseases on COVID-19 infection and role of new sensors and biomaterials for its detection and treatment

The entire world is suffering from a new type of viral disease, occurred by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The present article briefly discussed the genome sequencing and interaction of host cells with SARS-CoV-2. The influence of pre-existing diseases such as diabetes, heart disease and age of the patients on COVID-19 infection is reviewed. The possible treatments of SARS-CoV-2 including antiviral drugs, Chinese traditional treatment and plasma therapy are elaborately discussed. The proper vaccine for COVID-19 is not available till date. However, the trials of pre-existing antiviral vaccines such as, chloroquine/hydroxychloroquine, remdesivir, ritonavir and lopinavir and their consequences are briefly presented. Further, the importance of new materials and devices for the detection and treatment of COVID-19 has also been reviewed. The polymerase chain reaction (PCR)-based, and non-PCR based devices are used for the detection of COVID-19 infection. The non-PCR based devices provide rapid results as compared to PCR based devices.

Is highly expressed ACE 2 in pregnant women "a curse" in times of COVID-19 pandemic?

Angiotensin-converting enzyme 2 (ACE 2) is a membrane-bound enzyme that cleaves angiotensin II (Ang II) into angiotensin (1-7). It also serves as an important binding site for SARS-CoV-2, thereby, facilitating viral entry into target host cells. ACE 2 is abundantly present in the intestine, kidney, heart, lungs, and fetal tissues. Fetal ACE 2 is involved in myocardium growth, lungs and brain development. ACE 2 is highly expressed in pregnant women to compensate preeclampsia by modulating angiotensin (1-7) which binds to the Mas receptor, having vasodilator action and maintain fluid homeostasis. There are reports available on Zika, H1N1 and SARS-CoV where these viruses have shown to produce fetal defects but very little is known about SARS-CoV-2 involvement in pregnancy, but it might have the potential to interact with fetal ACE 2 and enhance COVID-19 transmission to the fetus, leading to fetal morbidity and mortality. This review sheds light on a path of SARS-CoV-2 transmission risk in pregnancy and its possible link with fetal ACE 2.

Management of Pregnant Inflammatory Bowel Disease Patients During the COVID-19 Pandemic

The rapid emergence of the novel coronavirus [SARS-CoV2] and the coronavirus disease 2019 [COVID-19] has caused significant global morbidity and mortality. This is particularly concerning for vulnerable groups such as pregnant women with inflammatory bowel disease [IBD]. Care for pregnant IBD patients in itself is a complex issue because of the delicate balance between controlling maternal IBD as well as promoting the health of the unborn child. This often requires continued immunosuppressive maintenance medication or the introduction of new IBD medication during pregnancy. The current global COVID-19 pandemic creates an additional challenge in the management of pregnant IBD patients. In this paper we aimed to answer relevant questions that can be encountered in daily clinical practice when caring for pregnant women with IBD during the current COVID-19 pandemic.

Neonatal and Children’s Immune System and COVID-19: Biased Immune Tolerance versus Resistance Strategy

The recent outbreak of COVID-19 has emerged as a major global health concern. Although susceptible to infection, recent evidence indicates mostly asymptomatic or mild presentation of the disease in infants, children, and adolescents. Similar observations were made for acute respiratory infections caused by other coronaviruses (severe acute respiratory syndrome and Middle East respiratory syndrome). These observations suggest that the immune system behaves differently in children than adults. Recent developments in the field demonstrated fundamental differences in the neonatal immune system as compared with adults, whereby infants respond to microorganisms through biased immune tolerance rather than resistance strategies. Similarly, more frequent/recent vaccinations in children and younger populations may result in trained immunity. Therefore, the physiological abundance of certain immunosuppressive cells, a tightly regulated immune system, and/or exposure to attenuated vaccines may enhance trained immunity to limit excessive immune reaction to COVID-19 in the young.

Clinical Profile of SARS-CoV-2 Infected Neonates From a Tertiary Government Hospital in Mumbai, India

Objectives

To describe the clinical and laboratory profile of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected neonates.

Methods

This is a review of hospital records, conducted in a tertiary care public hospital. Medical records of neonates born from 1 April, 2020 to 31 May, 2020 were reviewed. Women admitted in labor were screened for SARS-CoV-2 infection based on the guidelines issued by Indian Council for Medical Research. Neonates were tested for SARS-CoV-2 infection once mother tested positive, which was after day 2 of life. Demographic, clinical features, laboratory tests and chest radiographs of SARS-CoV-2 infected neonates were reviewed and neonates were telephonically followed up till the age of 2 months.

Results

Out of 1229 mothers, 185 tested positive (15.05%); 12 neonates (6.48%) tested positive for SARS-CoV-2 infection. All neonates were exclusively breastfed. Symptoms, if any, were mild and self-limiting. Serum lactate dehydrogenase and liver enzymes were elevated. All neonates were healthy and thriving well on follow-up.

Conclusion

SARS-CoV-2 infected neonates are mostly asymptomatic and thrive well on exclusive breastfeeding.

Ten key points about COVID-19 in children: The shadows on the wall

The pandemic of the new coronavirus disease-2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), initially described in China, is challenging the health care systems of all countries. Every emerging disease raises many questions with a scarcity of answers since all its characteristics are still being discovered. In the case of SARS-CoV-2, most of the literature comes from adult patients. Children seem to be less affected. Pediatric patients diagnosed with COVID-19 disease usually suffer a mild illness, with a low risk of complications, or mortality. Defining the role of children in the transmission of SARS-CoV-2 is critical as some national infection control decisions involving children, such as school closures or social distancing, will probably impact the dynamics of the virus. To aid in the knowledge of COVID-19 in children, this study presents an expert review of the literature published from 1 January to 28 May 2020, including peer-reviewed and preprint nonpeer-reviewed studies, along with some relevant articles afterward, summarizing ten key points that characterize the disease in children.

Outcomes in COVID-19 Positive Neonates and Possibility of Viral Vertical Transmission: A Narrative Review

OBJECTIVE

Novel coronavirus disease 2019 (COVID-19) seems to affect adults and pediatric patients differently. While neonates are a special population, little is known about the neonatal outcomes. This study aimed to investigate the outcomes in COVID-19 positive neonates and incidence of vertical transmission of the virus by reviewing available literature.

STUDY DESIGN

This study is a narrative review of available literature on "COVID-19 in neonates," for which PubMed and Google Scholar were used to search the published articles.

RESULTS

We summarized the data from 39 published studies that are comprised of 326 COVID-19 positive peripartum mothers with respective neonatal outcomes. Twenty-three neonates have been reported to be COVID-19 positive. Male neonates were affected significantly more (79%) than female neonates. Approximately 3% neonates acquired infection through suspected vertical transmission. Strict infection prevention measures during the perinatal time can significantly reduce the chance of horizontal transmission of the virus. Overall, neonates were asymptomatic or mildly symptomatic regardless of gestational age at birth and required only supportive measures. There was 0% mortality in COVID-19 positive neonates.

CONCLUSION

From available published data to date, we can conclude that the prognosis of COVID-19 positive neonates is good with no mortality. There appears to be minimal vertical transmission of the infection.

KEY POINTS

· Majority of COVID-19 positive neonates showed mild clinical signs and symptoms with no mortality.. · Most COVID-19 positive neonates require only supportive measures.. · Possibility of viral vertical transmission is very low..

Clinical characteristics of COVID-19 in children: A systematic review

BACKGROUND

Limited pediatric cases with coronavirus disease 2019 (COVID-19) have been reported and the clinical profiles regarding COVID-19 in children remain obscure. Our aim was to investigate the clinical characteristics of COVID-19 in children.

METHODS

PUBMED and EMBASE were searched through 20 June 2020, for case reports and case series reporting pediatric COVID-19 cases. Epidemiological, clinical, laboratory, and radiological data were collected and analyzed to compare by age.

RESULTS

Our search identified 46 eligible case reports and case series. A total of 114 pediatric cases with COVID-19 were included. The main clinical features were mild symptoms including fever (64%), cough (35%), and rhinorrhea (16%), or no symptoms (15%). Ground-like opacities were common radiological findings (54%). The main laboratory findings were lymphopenia (33%) and elevated D-dimer (52%) and C-reactive protein (40%) levels. We identified 17 patients (15%) with multisystem inflammatory syndrome in children (MIS-C) manifesting with symptoms overlapping with, but distinct from, Kawasaki disease, including gastrointestinal symptoms, left ventricular systolic dysfunction, shock, and marked elevated inflammatory biomarkers. Twelve percent of the patients including 65% of the MIS-C cases required intensive care because of hypotension. No deaths were reported.

CONCLUSION

This systematic review found that children with COVID-19 are generally less severe or asymptomatic. However, infants might be seriously ill and older children might develop MIS-C with severe illness. Early detection of children with mild symptoms or an asymptomatic state and early diagnosis of MIS-C are mandatory for the management of COVID-19 and the prevention of transmission and a severe inflammatory state.

Effects of Severe Acute Respiratory Syndrome Coronavirus 2 Infection on Pregnant Women and Their Infants

CONTEXT.—

The pandemic of a novel coronavirus, termed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has created an unprecedented global health burden.

OBJECTIVE.—

To investigate the effect of the SARS-CoV-2 infection on maternal, fetal, and neonatal morbidity and other poor obstetrical outcomes.

DESIGN.—

All suspected cases of pregnant women with coronavirus disease 2019 (COVID-19) admitted into one center in Wuhan from January 20 to March 19, 2020, were included. Detailed clinical data of those pregnancies with COVID-19 were retrospectively collected and analyzed.

RESULTS.—

Twenty-seven pregnant women (4 early pregnancies included) with laboratory or clinically confirmed SARS-CoV-2 infection and 24 neonates born to the 23 women in late pregnancy were analyzed. On admission, 46.2% (13 of 27) of the patients had symptoms, including fever (11 of 27), cough (9 of 27), and vomiting (1 of 27). Decreased total lymphocytes count was observed in 81.5% (22 of 27) of patients. Twenty-six patients showed typical viral pneumonia by chest computed tomography scan, whereas 1 patient confirmed with COVID-19 infection showed no abnormality on chest computed tomography. One mother developed severe pneumonia 3 days after her delivery. No maternal or perinatal death occurred. Moreover, 1 early preterm newborn born to a mother with the complication of premature rupture of fetal membranes, highly suspected to have SARS-CoV-2 infection, was SARS-CoV-2 negative after repeated real-time reverse transcriptase polymerase chain reaction testing. Statistical differences were observed between the groups of women in early and late pregnancy with COVID-19 in the occurrence of lymphopenia and thrombocytopenia.

CONCLUSIONS.—

No major complications were reported among the studied cohort, though 1 serious case and 1 perinatal infection were observed. Much effort should be made to reduce the pathogenic effect of COVID-19 infection in pregnancies.

How should our testing behaviour change with time in children in current COVID-19 pandemic?

BACKGROUNDS

More paediatric-confirmed cases have been reported with the global pandemic of COVID-19. This study aims to summarize the key points and supply suggestions on screening paediatric COVID-19 patients more appropriately.

MATERIALS AND METHODS

We retrospectively included paediatric patients who have accepted SARS-CoV-2 RT-PCR testing in Children's Hospital of Chongqing Medical University (30 January 2020 to 13 February 2020) and compared them with paediatric-confirmed COVID-19 cases. Besides, a review was carried out by analysing all current literature about laboratory-confirmed paediatric cases with COVID-19.

RESULTS

There were 46 suspected cases included in the descriptive study. The results of SARS-CoV-2 RT-PCR testing were all negative. Compared with paediatric-confirmed cases, the incidence of epidemic history was lower in suspected cases (P < .001). The rate of fever (P < .001), cough (P < .001), headache or dizziness (P < .001), vomiting (P < .001) and abdominal discomfort or distention (P = .01) were more observed in the included suspected children. There were more children having decreased WBC count in the confirmed group. In the literature review, twenty-nine studies were obtained with 488 paediatric COVID-19 cases. 88.6% of them had epidemiological history. Cough and fever were the most common symptoms. Compared with older patients, the incidence of fever, respiratory symptoms, lethargy and headache or dizziness was lower, while gastrointestinal symptoms were reported more.

CONCLUSIONS

Children with a history of close contact with confirmed cases, manifested as cough and fever should be paid more attention to after excluding infection of other common pathogens. Atypical symptoms should not be over-emphasized in screening paediatric COVID-19. More studies are needed for guiding efficient recognition in paediatric COVID-19.
