Community-acquired neonatal SARS-CoV-2 infection: case report

Background and Objectives: Data collection on the incidence of COVID-19 is conducted less frequently in newborns (NB) than in adults. In view of the small number of described neonatal SARS-CoV-2 infections, in this study, we report a clinical case of community-acquired COVID-19 infection in a newborn. Methods: Clinical characteristics were collected from the medical records from April 2021 until the final outcome of the newborn in May 2021. Results: This article discusses the case of a full-term male newborn aged 38 weeks. On the 17th day of life, this newborn was admitted to the pediatric unit with fever and zone 4 jaundice, mild lower chest retraction and tachypnea. The mother was diagnosed with COVID-19. Late neonatal sepsis with pulmonary focus was detected. The newborn was hospitalized and the antigen test for COVID-19 came back positive. The condition of the neonate rapidly deteriorated and he was referred to the neonatal intensive care unit (NICU), where he was intubated and placed on pressure-controlled mechanical ventilation. During his second week in the NICU, he developed severe pulmonary hypertension with decreased peripheral oxygen saturation and tachycardia. The newborn required blood transfusion and was put into prone position during part of the treatment. Reductions in mechanical ventilation parameters were not tolerated by the NB’s organism and he developed progressive hypoxemia. The newborn died 1 month and 3 days after hospitalization. Conclusion: Our study shows a case of community-acquired COVID-19 that progressed to the severe form of the disease.

Evaluation of Ema, Töllner and Rodwell scores in the diagnosis of neonatal sepsis

Introduction: There are no specific signs, symptoms and rapid laboratory tests to definitively diagnose sepsis in the neonatal period. This makes it difficult to diagnose sepsis in newborns in a timely manner and initiate appropriate treatment, or causes babies without sepsis to receive unnecessary antibiotics. Purpose: Therefore, in this study, we planned to investigate the clinical adequacy and reliability of EMA (European Medicines Agency), Töllner and Rodwell hematological scoring in the early diagnosis of neonatal sepsis. Method: EMA, Töllner and Rodwell hematological scoring was performed on each patient. Complete blood count, peripheral smear, C-reactive protein, procalcitonin, blood gas and blood sugar values of newborn babies with suspected sepsis were recorded, blood culture, urine culture and cerebrospinal fluid examination and cultures taken when necessary were evaluated. Using statistical analysis, the 'Positive Expected Value and Negative Expected Values' ratios of the scores were obtained, and the performance results were examined. Results: 95 newborns with a preliminary clinical diagnosis of sepsis were included in the study. These babies were divided into two groups: clinical (n:71) and proven sepsis (n:24) according to blood culture results. Positive and negative predictive values of scoring systems in definitive sepsis diagnosis; for EMA respectively; 21.5%, 56.3% for Töllner; It was determined as 31.3%, 77.8%, and 100%, 77.8% for Rodwell. Conclusion: Our study showed that clinician opinion and standard laboratory tests are limited in the diagnosis of neonatal sepsis, and Rodwell hematological scoring is more prominent in recognizing proven sepsis compared to the other two scores .

From diagnosis to management: current perspectives on congenital cytomegalovirus infection.

Congenital CMV (cCMV) infection is the most common infection of newborns and a leading cause of hearing loss and other neurologic disabilities in children. This review focuses on the diagnosis, presentation and management of cCMV infection. Cytomegalovirus is one of the leading causes of sensorineural hearing loss in children. It also leads to neurodevelopmental disabilities and learning problems throughout childhood in both symptomatic and asymptomatic newborns. Urine and saliva PCR testing are the preferred methods of testing newborn infants for cCMV. In recent years, newborn-targeted and universal screening programs have been implemented in several states and major medical centers with the goal of identifying infected infants at risk for hearing loss. Treatment for infants diagnosed with cCMV infection should be limited to those who are moderately to severely symptomatic at birth with cCMV infection, though treatment may be beneficial for children who are asymptomatic with isolated sensorineural hearing loss. As more children with cCMV are being identified through newborn screening, understanding the clinical presentation and sequelae is important for appropriate management of children with cCMV.

Quantitative EEG features during the first day correlate to clinical outcome in perinatal asphyxia.

To assess whether computational electroencephalogram (EEG) measures during the first day of life correlate to clinical outcomes in infants with perinatal asphyxia with or without hypoxic-ischemic encephalopathy (HIE). We analyzed four-channel EEG monitoring data from 91 newborn infants after perinatal asphyxia. Altogether 42 automatically computed amplitude- and synchrony-related EEG features were extracted as 2-hourly average at very early (6 h) and early (24 h) postnatal age; they were correlated to the severity of HIE in all infants, and to four clinical outcomes available in a subcohort of 40 newborns: time to full oral feeding (nasogastric tube NGT), neonatal brain MRI, Hammersmith Infant Neurological Examination (HINE) at three months, and Griffiths Scales at two years. At 6 h, altogether 14 (33%) EEG features correlated significantly to the HIE grade ([r]= 0.39-0.61, p < 0.05), and one feature correlated to NGT ([r]= 0.50). At 24 h, altogether 13 (31%) EEG features correlated significantly to the HIE grade ([r]= 0.39-0.56), six features correlated to NGT ([r]= 0.36-0.49) and HINE ([r]= 0.39-0.61), while no features correlated to MRI or Griffiths Scales. Our results show that the automatically computed measures of early cortical activity may provide outcome biomarkers for clinical and research purposes. The early EEG background and its recovery after perinatal asphyxia reflect initial severity of encephalopathy and its clinical recovery, respectively. Computational EEG features from the early hours of life show robust correlations to HIE grades and to early clinical outcomes. Computational EEG features may have potential to be used as cortical activity biomarkers in early hours after perinatal asphyxia.

Bilirubin Exerts Protective Effects on Alveolar Type II Pneumocytes in an In Vitro Model of Oxidative Stress.

Newborn infants face a rapid surge of oxygen and a more protracted rise of unconjugated bilirubin after birth. Bilirubin has a strong antioxidant capacity by scavenging free radicals, but it also exerts direct toxicity. This study investigates whether cultured rat alveolar epithelial cells type II (AEC II) react differently to bilirubin under different oxygen concentrations. The toxic threshold concentration of bilirubin was narrowed down by means of a cell viability test. Subsequent analyses of bilirubin effects under 5% oxygen and 80% oxygen compared to 21% oxygen, as well as pretreatment with bilirubin after 4 h and 24 h of incubation, were performed to determine the induction of apoptosis and the gene expression of associated transcripts of cell death, proliferation, and redox-sensitive transcription factors. Oxidative stress led to an increased rate of cell death and induced transcripts of redox-sensitive signaling pathways. At a non-cytotoxic concentration of 400 nm, bilirubin attenuated oxidative stress-induced responses and possibly mediated cellular antioxidant defense by influencing Nrf2/Hif1α- and NFκB-mediated signaling pathways. In conclusion, the study demonstrates that rat AEC II cells are protected from oxidative stress-induced impairment by low-dose bilirubin.

The gut microbiome, resistome, and mycobiome in preterm newborn infants and mouse pups: lack of lasting effects by antimicrobial therapy or probiotic prophylaxis

BackgroundEnhancing our understanding of the underlying influences of medical interventions on the microbiome, resistome and mycobiome of preterm born infants holds significant potential for advancing infection prevention and treatment strategies. We conducted a prospective quasi-intervention study to better understand how antibiotics, and probiotics, and other medical factors influence the gut development of preterm infants. A controlled neonatal mice model was conducted in parallel, designed to closely reflect and predict exposures. Preterm infants and neonatal mice were stratified into four groups: antibiotics only, probiotics only, antibiotics followed by probiotics, and none of these interventions. Stool samples from both preterm infants and neonatal mice were collected at varying time points and analyzed by 16 S rRNA amplicon sequencing, ITS amplicon sequencing and whole genome shotgun sequencing.ResultsThe human infant microbiomes showed an unexpectedly high degree of heterogeneity. Little impact from medical exposure (antibiotics/probiotics) was observed on the strain patterns, however, Bifidobacterium bifidum was found more abundant after exposure to probiotics, regardless of prior antibiotic administration. Twenty-seven antibiotic resistant genes were identified in the resistome. High intra-variability was evident within the different treatment groups. Lastly, we found significant effects of antibiotics and probiotics on the mycobiome but not on the microbiome and resistome of preterm infants.ConclusionsAlthough our analyses showed transient effects, these results provide positive motivation to continue the research on the effects of medical interventions on the microbiome, resistome and mycobiome of preterm infants.

Isolated Finding of Acalvaria in a Newborn Infant

Acalvaria is a rare congenital malformation of unknown etiopathogenesis that affects the development of the skull and surrounding muscular structures. There is scant literature regarding the pathophysiology, and no standardized guidelines exist for patient management. Herein, we present a case of acalvaria in a newborn and our multidisciplinary approach from diagnosis to 1 year of age.

A mixed-methods study to investigate feasibility and acceptability of an early warning score for preterm infants in neonatal units in Kenya: results of the NEWS-K study

Preterm birth (< 37 weeks gestation) complications are the leading cause of neonatal mortality. Early-warning scores (EWS) are charts where vital signs (e.g., temperature, heart rate, respiratory rate) are recorded, triggering action. To evaluate whether a neonatal EWS improves clinical outcomes in low-middle income countries, a randomised trial is needed. Determining whether the use of a neonatal EWS is feasible and acceptable in newborn units, is a prerequisite to conducting a trial. We implemented a neonatal EWS in three newborn units in Kenya. Staff were asked to record infants’ vital signs on the EWS during the study, triggering additional interventions as per existing local guidelines. No other aspects of care were altered. Feasibility criteria were pre-specified. We also interviewed health professionals (n = 28) and parents/family members (n = 42) to hear their opinions of the EWS. Data were collected on 465 preterm and/or low birthweight (< 2.5 kg) infants. In addition to qualitative study participants, 45 health professionals in participating hospitals also completed an online survey to share their views on the EWS. 94% of infants had the EWS completed at least once during their newborn unit admission. EWS completion was highest on the day of admission (93%). Completion rates were similar across shifts. 15% of vital signs triggered escalation to a more senior member of staff. Health professionals reported liking the EWS, though recognised the biggest barrier to implementation was poor staffing. Newborn unit infant to staff ratios varied between 10 and 53 staff per 1 infant, depending upon time of shift and staff type. A randomised trial of neonatal EWS in Kenya is possible and acceptable, though adaptations are required to the form before implementation.

Cost-effectiveness Analysis of Maternal Immunization with RSVpreF Vaccine for the Prevention of Respiratory Syncytial Virus Among Infants in Spain.

Respiratory syncytial virus (RSV) is the leading cause of acute lower respiratory infections (ALRI) in children under one year of age. In high-income countries, RSV infections cause a significant overload of care every winter, imposing a significant burden to the healthcare system, which has made the development of prevention strategies a major global health priority. In this context, a new bivalent RSV prefusion F protein-based vaccine (RSVpreF) has recently been approved. The objective of this study was to evaluate the cost-effectiveness of vaccinating pregnant women with the RSVpreF vaccine to prevent RSV in infants from the Spanish National Healthcare System (NHS) perspective. A hypothetical cohort framework and a Markov-type process were used to estimate clinical outcomes, costs, quality-adjusted life years (QALY) and cost-per-QALY gained (willingness-to-pay threshold: €25,000/QALY) for newborn infants born to RSV-vaccinated versus unvaccinated mothers over an RSV season. The base case analysis was performed from the NHS perspective including direct costs (€2023) and applying a discount of 3% to future costs and outcomes. To evaluate the robustness of the model, several scenarios, and deterministic and probabilistic analyses were carried out. All the parameters and assumptions were validated by a panel of experts. The results of the study showed that year-round maternal vaccination program with 70% coverage is a dominant option compared to no intervention, resulting in direct cost savings of €1.8 million each year, with an increase of 551 QALYs. Maternal vaccination could prevent 38% of hospital admissions, 23% of emergency room visits, 19% of primary care visits, and 34% of deaths due to RSV. All scenario analyses showed consistent results, and according to the probabilistic sensitivity analysis (PSA), the probability of maternal vaccination being cost-effective versus no intervention was 99%. From the Spanish NHS perspective, maternal vaccination with bivalent RSVpreF is a dominant alternative compared with a non-prevention strategy.

Evolution of Exclusive Breastfeeding Practices According to Continuous Demographic and Health Surveys (DHS-C) from 2010-2011 to 2019 and Associated Factors in Senegal

Introduction: The first two years of a child&amp;apos;s life are particularly important. Inadequate breastfeeding practices during this period considerably compromise the health, development and survival of infants, children and mothers. Several studies have assessed the impact of breastfeeding on infant mortality. The objectives of our study were to investigate changes in exclusive breastfeeding practices during the first six months of life according to DHS data from 2010-2011 to 2019 and to identify the various associated factors. Methodology: This is a quantitative analysis of secondary data based on cross-sectional data from the DHS from 2010-2011 to 2019 on changes in exclusive breastfeeding practices for infants under six months of age. Our study focused on women aged 15 to 49 years interviewed during the DHS and residing in Senegal at the time of the various surveys who had children under two years of age. Data were collected on exclusive breastfeeding rates in different years, the socio-demographic and gyneco-obstetric characteristics of mothers, and the characteristics of newborn children. A multivariate analysis was performed to identify factors associated with exclusive breastfeeding. Results: showed that exclusive breastfeeding rates remained below 50% from 2010-11 to 2019. Analysis by region showed a disparity between the different regions. The associated factors were: ethnic group: Wolof are less likely to practice EBF with an adjusted AOR of 0.59 with a CI&amp;lt;sub&amp;gt;95&amp;lt;/sub&amp;gt;: [0.38, 0. 90], maternal literacy: mothers who could not read were less likely to perform EBF with an adjusted AOR of 0.71 and a CI&amp;lt;sub&amp;gt;95&amp;lt;/sub&amp;gt;: [0.53-095], birth order: mothers with 6 or more children were more likely to perform EBF, with an AOR of 3.20 and a CI&amp;lt;sub&amp;gt;95&amp;lt;/sub&amp;gt;: [1.68-6.17], maternal occupation: Working mothers were less likely to practice EBF than non-working mothers, with an AOR of 0.60 and a CI&amp;lt;sub&amp;gt;95&amp;lt;/sub&amp;gt; [0.46-0.79], access to the media: Mothers with access to the media were less likely to practice assisted fertilization, with an AOR of 0.57 and a CI&amp;lt;sub&amp;gt;95&amp;lt;/sub&amp;gt;: [0.37-0.90] and use of modern contraception: Mothers using modern contraception were less likely to practice exclusive breastfeeding, with an AOR of 0.53 and a CI&amp;lt;sub&amp;gt;95&amp;lt;/sub&amp;gt;: [0.38-0.72]. Conclusion: Despite all the efforts made by the Senegalese government and its technical and financial partners, rates are still low. To strengthen the practice of exclusive breastfeeding, it is important and urgent to design and implement innovative evidence-based interventions covering the different levels of the socio-ecological model (individuals, families, communities and public policies).

ISOLATED CONGENITAL GENU RECURVATUM A CASE SERIES

Congenital Genu Recurvatum (CGR) is a rare anomaly which can be diagnosed prenatally via imaging or following birth by a physical examination. With an incidence of 1 in 100,000 live births, CGR is defined as a pathological degree of hyperextension of the knee joint accompanied by limited flexion. CGR may occur in isolation or in association with other birth defects such as talipes equinovarus and a congenital dislocation of the hip joint. In severe cases of CGR, contracture of the quadriceps tendon does not permit reduction. At the other end of the severity spectrum, where the dislocated knee yields to reduction through manual manipulation, conservative treatment with serial Plaster of Paris (POP) casting of the joint in the reduced position has demonstrated excellent outcome. Newborn babies born in our institution during the period 2019-2022 with isolated unilateral congenital dislocation of knee joint managed conservatively is followed up till 3 months. Based on our experience, we conclude that serial casting is has shown excellent functional outcomes in patients with grade 3 isolated congenital genu recurvatum managed by manipulation and serial casting

Does heart rate variability using the Newborn Infant Parasympathetic Evaluation index identify postsurgical pain levels and emergence delirium in toddlers? A prospective observational study.

Children recovering from anesthesia commonly experience early postoperative negative behaviour, caused by pain and emergence delirium. Differentiating the two is challenging in young children. Perioperative pain influences the heart rate variability-derived Newborn Infant Parasympathetic Evaluation (NIPE) index and may also affect emergence delirium. We sought to investigate whether the perioperative NIPE index can discriminate between mild, moderate, or severe pain levels and can detect emergence delirium. This prospective observational study enrolled children aged three years or younger undergoing elective adenotonsillectomy, tonsillectomy, or adenoidectomy. The NIPE index, the Faces, Legs, Activity, Cry, Consolability (FLACC) score, and the Pediatric Anesthesia Emergence Delirium (PAED) score were recorded in the postanesthesia care unit (PACU). The primary aim was to investigate the relationship between the postoperative NIPE index and postoperative pain severity. The secondary aims were to evaluate the association between the NIPE index and emergence delirium (PAED ≥ 10) and its delirium-specific (ED-I) and pain-specific (ED-II) components. Sixty-nine children were recruited. In the PACU, the mean (standard deviation [SD]) NIPE values in children experiencing moderate and severe pain were 50 (12) and 49 (14), respectively. These values were significantly lower than the mean (SD) value of 64 (13) observed in children with mild pain (mean difference moderate vs no/mild pain, -14; 95% confidence interval [CI], -17 to -11; P < 0.001, and mean difference severe vs no/mild pain, -17; 95% CI, -20 to -14; P < 0.001, respectively). The NIPE index was significantly lower in children experiencing pain-specific ED-II (mean [SD] NIPE instantaneous [NIPEi] for ED-II 49 [10] vs no ED-II 55 [13]; mean difference, -6; 95% CI, -11 to -2; P = 0.009). The NIPE index was unable to detect emergence delirium (mean [SD] NIPEi for ED, 54 [15] vs no ED, 51 [10]; mean difference, 3; 95% CI, -2 to 8; P = 0.23) or the delirium-specific component ED-I (mean [SD] NIPEi for ED-I, 55 [15] vs no ED-I, 51 [11]; mean difference, 4; 95% CI, 0 to 8; P = 0.06). The NIPE index can identify moderate and severe postoperative pain after adenotonsillectomy but not emergence delirium in children aged three years and younger. This discrimination can be valuable in the early postoperative phase when the differentiation between pain and emergence delirium is difficult.

Newborn care knowledge and practices among care givers of newborns and young infants attending a regional referral hospital in Southwestern Uganda.

A child born in developing countries has a 10 times higher mortality risk compared to one born in developed countries. Uganda still struggles with a high neonatal mortality rate at 27/1000 live births. Majority of these death occur in the community when children are under the sole care of their parents and guardian. Lack of knowledge in new born care, inappropriate new born care practices are some of the contributors to neonatal mortality in Uganda. Little is known about parent/caregivers' knowledge, practices and what influences these practices while caring for the newborns. We systematically studied and documented newborn care knowledge, practices and associated factors among parents and care givers. To assess new born care knowledge, practices and associated factors among parents and care givers attending MRRH. We carried out a quantitative cross section methods study among caregivers of children from birth to six weeks of life attending a regional referral hospital in south western Uganda. Using pretested structured questionnaires, data was collected about care givers' new born care knowledge, practices and the associated factors. Data analysis was done using Stata version 17.0. We interviewed 370 caregivers, majority of whom were the biological mothers at 86%. Mean age was 26 years, 14% were unemployed and 74% had monthly earning below the poverty line. Mothers had a high antenatal care attendance of 97.6% and 96.2% of the deliveries were at a health facility Care givers had variant knowledge of essential newborn care with associated incorrect practices. Majority (84.6%) of the respondents reported obliviousness to putting anything in the babies' eyes at birth, however, breastmilk, water and saliva were reportedly put in the babies' eyes at birth by some caregivers. Hand washing was not practiced at all in 16.2% of the caregivers before handling the newborn. About 7.4% of the new borns received a bath within 24 hours of delivery and 19% reported use of herbs. Caregivers practiced adequate thermal care 87%. Cord care practices were inappropriate in 36.5%. Only 21% of the respondents reported initiation of breast feeding within 1 hour of birth, Prelacteal feeds were given by 37.6% of the care givers, water being the commonest prelacteal feed followed by cow's milk at 40.4 and 18.4% respectively. Majority of the respondents had below average knowledge about danger signs in the newborn where 63% and mean score for knowledge about danger signs was 44%. Caretaker's age and relationship with the newborn were found to have a statistically significant associated to knowledge of danger signs in the newborn baby. There are variable incorrect practices in the essential new born care and low knowledge and awareness of danger signs among caregivers of newborn babies. There is high health center deliveries and antenatal care attendance among the respondents could be used as an opportunity to increase caregiver awareness about the inappropriate practices in essential newborn care and the danger signs in a newborn.

Neonatal Scurvy- A Rare Case Report

Scurvy, a disease of vitamin C deficiency, is now considered as a rare disease in paediatric population. The human body is dependent on the external supply of vitamin C. The newborn infant receives this from breast milk. Therefore, infantile scurvy is generally observed only in infants over the age of three months. The occurrence of scurvy before that age is extremely rare. We described a case of neonatal scurvy in a 28 days old boy who was on parenteral nutrition for initial 10 days of age due to neonatal sepsis with perinatal asphyxia.

Kejadian Ketuban Pecah Dini terhadap Infeksi Neonatorum di Ruang Perinatologi RSUD Kota Madiun

Premature Rupture of Membranes (PRM) the rupture of the amniotic membrane before delivery can have consequences for the mother and baby, and can result in neonatal infections. The aim of the study was to determine the relationship between the incidence of premature rupture of membranes and the incidence of neonatal infections in Perinatology at the Madiun City General Hospital. Type of research is correlation analytic, retrospective cohort research design with a documentation study approach. The population was all newborn babies whose mothers experienced PROM from July 2022 to July 2023. The sample was 158 mothers who gave birth using simple random sampling. Research in the Perinatology Room at Madiun City Regional Hospital starting in August 2023. Independent variable is premature rupture of membranes. Neonatal infection research variables. Analysis tests using the Chi Square Test. The results of the research that almost all respondents had a duration of KPD ≥ 12 hours, 146 people (92.4%), almost all respondents experienced neonatal infections, 124 people (78.5%), the Chi Square test produced Sig. (2-tailed) is 0.013, meaning there is a relationship between the incidence of premature rupture of membranes and the incidence of neonatal infection in the Madiun City Regional Hospital with a very weak relationship level because the relationship value is 0.195. Mothers who gave birth to KPD ≥ 12 hours did not cause neonatal infections, namely that health workers increased their self-protection to prevent infection in newborns by not frequently carrying out internal examinations on women who gave birth who experienced KPD, giving antibiotics and you need to wash your hands properly

Point-of-Care Newborn Screening for Sickle Cell Disease at Selected Health Facilities in the Gambia

Sickle cell disease (SCD) contributes significantly to childhood morbidity and mortality in sub-Saharan Africa. Early diagnosis through newborn screening (NBS) and subsequent comprehensive follow-up care will reduce the burden. Up till now, the prevalence of SCD among newborns remains unknown in The Gambia and there is no national NBS programme to address this significant public health issue. We assessed the real-time frequency of SCD in the country and determined differences in the pattern of SCD phenotypes among different ethnic groups. A preliminary prospective feasibility study was done in eight purposively selected hospitals in the seven Health Administrative Regions and Banjul. Consecutive newborn babies delivered or managed in these facilities were screened using HemoTypeSC, a sensitive and specific ELISA-based point-of-care test (POCT). Babies identified as SCD with HemoTypeSC were retested at age ≥6 months using alkaline cellulose acetate hemoglobin electrophoresis (ACAE). Head-to-head comparison between HemoType screening and gold standard HPLC could not be done. 1,168 newborn babies were screened from April 14 to August 12, 2023. Fifteen (1.3%) had homozygous HbS (HbSS), two (0.2%) heterozygous for HbS and HbC (HbSC), 204 (17.5%) had sickle cell trait (HbAS), four (0.3%) heterozygous for HbA and HbC (HbAC), and 943 (80.7%) had normal hemoglobin (HbAA). The 17 with SCD (HbSS and HbSC) comprised of 7 (2.2%) of 324 Fula; 6 (1.4%) of 426 Mandinka; 2 (1.6%) of 125 Jola and 2 (1.3%) of 150 Wolof. Fourteen (82.4%) of the 17 accepted the diagnosis and were enrolled into the SCD program. For these 14, HemoTypeSC had 100% sensitivity with ACAE when repeated at age ≥6 months. In addition to determining the real-time newborn prevalence of SCD and trait in The Gambia for the first time, this pilot study showed that SCD-POCT is feasible in Gambian health facilities.

Human Milk Oligosaccharides in Antenatal Colostrum: A Case Study.

Introduction/Background: Some women produce antenatal colostrum during pregnancy and feed it to their baby after birth. However, the composition of antenatal colostrum and how it compares to postnatal colostrum and mature milk are not well described. In fact, there are currently no data on the composition of antenatal colostrum when it comes to human milk oligosaccharides (HMOs), the third most abundant solid human milk component after lactose and lipids. Case Presentation: We report a case of a single healthy donor who collected antenatal colostrum and urine from 19 weeks of gestation all the way to mature milk at 3 months postpartum. We analyzed all samples for HMO composition using high-performance liquid chromatography and for lactose concentrations using an enzymatic assay. Results: The entire spectrum of HMOs typical of a nonsecretor was already present in antenatal colostrum at 19 weeks gestation with a total concentration of 7.5 mg/mL. The HMO concentration further increased to over 12.5 mg/mL at 30 weeks gestation and then declined throughout the remainder of pregnancy and continued to decline in the postpartum period with concentrations of less than 5 mg/mL at 12 weeks postpartum. Concentrations of some of the individual HMOs as well as lactose changed significantly at the time of birth. HMO composition in antenatal colostrum was different in time-matched urine samples. Conclusion: Measuring HMOs in maternal urine does not fully capture the composition of HMOs in antenatal colostrum. Feeding antenatal colostrum to the newborn baby provides the entire set of different HMOs at high concentrations.

Serological profile of hepatitis B virus infection among traditional birth attendants and the attending pregnant women in Ibadan, Nigeria

ABSTRACT Although a sizable number of pregnant women patronize Traditional Birth Attendants (TBAs) for deliveries in Nigeria, efforts to prevent or reduce the risk of HBV transmission are not targeted at the TBAs and the pregnant women patronizing them. This may be linked to the dearth of information on the serological profiles of HBV among this cohort. We, therefore, show the serological profiles of HBV among the cohort. One hundred and seventy pregnant women and 91 TBAs participated in this study between May and July 2019. Serological markers of HBV infection were assayed using ELISA. A prevalence of, 8.0% (95% CI: 5.0% − 11.5%) for HBsAg, 0.8% (95% CI: 0.0% − 1.9%) for HBeAg, 2.7% (95% CI: 0.8% − 5.0%) for HBcIgM, 26.1% (95% CI: 20.7% − 31.4%) for anti-HBs, 21.5% (95% CI: 16.5% − 25.4%) for anti-HBe and 67.0% (95% CI: 60.9% – 72.8%) for anti-HBc was found indicating a high percentage of carriers. Although 32 (12.3%) of the entire participants claimed to be fully vaccinated, serological evidence was only detected in 4 (12.5%). The high percentage of carriers and low evidence of vaccination necessitate intensified efforts to ensure that adequate interventions are made available and accessible to the TBAs and the pregnant women patronizing them (including newborn babies).

It is Time to Screen for Homozygous Familial Hypercholesterolemia in the United States.

Homozygous familial hypercholesterolemia (HoFH) is an ultra-rare inherited condition that affects approximately one in 300,000 people. The disorder is characterized by extremely high, life-threatening levels of low-density lipoprotein (LDL) cholesterol from birth, leading to significant premature cardiovascular morbidity and mortality, if left untreated. Homozygous familial hypercholesterolemia is severely underdiagnosed and undertreated in the United States (US), despite guidelines recommendations for universal pediatric lipid screening in children aged 9-11. Early diagnosis and adequate treatment are critical in averting premature cardiovascular disease in individuals affected by HoFH. Yet, an unacceptably high number of people living with HoFH remain undiagnosed, misdiagnosed, and/or receive a late diagnosis, often after a major cardiovascular event. The emergence of novel lipid-lowering therapies, along with the realization that diagnosis is too often delayed, have highlighted an urgency to implement policies that ensure timely detection of HoFH in the US. Evidence from around the world suggests that a combination of universal pediatric screening and cascade screening strategies constitutes an effective approach to identifying heterozygous familial hypercholesterolemia (HeFH). Nevertheless, HoFH and its complications manifest much earlier in life compared to HeFH. To date, little focus has been placed on the detection of HoFH in very young children and/or infants. The 2023 Updated European Atherosclerosis Society Consensus Statement on HoFH has recommended, for the first time, broadening pediatric guidelines to include lipid screening of newborn infants. Some unique aspects of HoFH need to be considered before implementing newborn screening. As such, insights from pilot studies conducted in Europe may provide some preliminary guidance. Our paper proposes a set of actionable measures that states can implement to reduce the burden of HoFH. It also outlines key research and policy gaps that need to be addressed in order to pave the way for universal newborn screening of HoFH in the US.

Association of antenatal or neonatal SARS-COV-2 exposure with developmental and respiratory outcomes, and healthcare usage in early childhood: a national prospective cohort study

Perinatal exposure to SARS-CoV-2 may affect neurodevelopment before 12 months of age, but longer-term outcomes remain unknown. We examined whether antenatal or neonatal SARS-CoV-2 exposure compared with non-exposure is associated with neurodevelopment, respiratory symptoms, and health care usage in early childhood. This prospective national population-based cohort study was conducted in England and Wales, United Kingdom. We enrolled term-born children (≥37 weeks' gestation) with and without antenatal or neonatal exposure to SARS-CoV-2 infection by approaching parents of eligible children who were cared for in 87 NHS hospitals. Potential participants were identified through the national active surveillance studies of pregnant women and newborn infants hospitalised with confirmed SARS-CoV-2 infection conducted through the UK Obstetric Surveillance System and the British Paediatric Surveillance Unit. We defined antenatal and neonatal SARS-CoV-2 exposure as infants born to mothers hospitalised with confirmed SARS-CoV-2 infection between 14+0 and 36+6 weeks gestation and infants admitted to hospital with confirmed SARS-CoV-2 infection within the first 28 days after birth. Children born preterm or with major congenital anomaly or who were not residing in the UK were excluded. We assessed children's development (Ages and Stages Questionnaire 3rd Edition (ASQ-3); Ages and Stages Questionnaire Social-Emotional 2nd Edition (ASQ:SE-2)), respiratory symptoms (Liverpool Respiratory Symptom Questionnaire (LRSQ)) and health care usage (parent-completed questionnaire) at 21-32 months of age. Primary outcome: total ASQ-3 score, converted to z-scores. Secondary outcomes: ASQ:SE-2 z-scores; risk of delay in ASQ-3 domains; total LRSQ scores, converted to z-scores. Analyses were adjusted for children's age, sex, maternal ethnicity, parental education, and index of multiple deprivation. Between October 20, 2021 and January 27, 2023, we approached 668 and 1877 families out of 712 and 1917 potentially eligible participants in the exposed and comparison cohort. Of the 125 and 306 participants who were enrolled to the exposed and comparison cohort 121 and 301 participants completed the questionnaires and 96 and 243 participants were included in the analysis. In the age adjusted analysis, the mean total ASQ-3 z-score was lower in the exposed than the comparison cohort (-0.3, 95% CI:-0.6 to-0.05), however, when adjusted for sex, parental education, ethnicity and IMD quintile, there was no significant difference (difference in mean z-score=-0.2 95% CI:-0.5 to 0.03). SARS-CoV-2 exposure was associated with increased risk of delayed personal-social skills (odds ratio=3.81; 95% CI: 1.07-13.66), higher ASQ:SE-2 total z-scores (difference in mean z-score=0.4; 95% CI: 0.2-0.6) and increased risk of delayed social-emotional development (OR=3.58, 95% CI: 1.30-9.83), after adjusting for sex, age at assessment, parental education, ethnicity and IMD quintile. The exposed cohort had a higher mean total LRSQ z-score than the comparison cohort (0.3 95% CI: 0-0.6) and higher inpatient (38% vs. 21%, p=0.0001), outpatient (38% vs. 30%, p=0.0090), and General Practitioner appointments (60% vs. 50%, p=0.021) than the comparison cohort, after adjusting for sex, age at assessment, parental education, ethnicity and IMD quintile. No differences in other secondary outcomes between the exposed and comparison cohorts were found. Although the exposed cohort did not differ from the comparison cohort on the primary outcome, total ASQ-3 score, the exposed cohort were at greater risk of delayed social-emotional development, had a greater prevalence of respiratory symptoms and increased health care usage relative to the comparison cohort. The study is limited by the smaller sample size due to the low response rate and lack of clinical developmental assessments. Given the association of poor social-emotional development with antenatal or neonatal SARS-CoV-2 exposure, developmental screening, and follow-up of children with confirmed antenatal or neonatal SARS-CoV-2 infection may be warranted to identify those in need of early intervention.
