Assessment of Hearing Impairment in Sick Newborns: A Prospective Observational Study.

Undiagnosed neonatal hearing loss causes severe language, cognitive, and behavioral problems in children. Sick newborns who spend 48 hours in the neonatal intensive care unit (NICU) have a 10- to 20-fold increased risk of permanent hearing loss.The aim of this study is to identify hearing impairment in high-risk sick newborns who spend at least 48 hours in the NICU. The present prospective observational study was conducted at a single center.All sick neonates admitted to the NICU for a minimum of 48 hours at the JK Lon Hospital, Zanana Hospital, and Mahila Chikitsalaya, Sawai Man Singh (SMS) Medical College, Jaipur,Rajasthan, India, from June 2017 to May 2018 were considered eligible for the study.The primary outcome was the assessment of hearing loss of high-risk newborns using otoacoustic emissions at the time of discharge, six weeks of age, and automated auditory brainstem response (AABR) at three months of chronological age. The secondary outcome was to analyze the association of hearing loss with different risk factors in high-risk neonates. A total of 150 infants who had one or more risk factors were studied, 60 were female and 90 were male. No statistically significant difference in hearing loss was observed based on birth weight, sex, and gestational age.The firstdistortion-product otoacoustic emission(DPOAE) screening was done on infants at the time of discharge from the NICU. Eighty-three infants (55.33%) had "refer" on the first DPOAE and the remaining 67 (44.67%) were passed results at the time of discharge.At six weeks of life, on repeat screening with a second DPOAE test, 36% "refer"on the first screen had a"refer"result on the second DPOAE. However, 4.4% "pass" on the first screen turned out to be"refer"on the second screen. These 33 infants who had"refer"results on the second screen were subjected to testing.At 10 weeks of life, AABR wasperformedon 33 infants. Eleven infants out of 33 had sensorineural hearing loss (SNHL) on AABR. Hearing impairment with the DPOAE test was observed with risk factors neonatal hyperbilirubinemia (NHH), hypoxic ischemic encephalopathy (HIE), and very low birth weight (VLBW) and was statistically significant among all risk factors.But, no such association (between hearing impairment and risk factors) was observed with the AABR test. In our study, we found that the duration of mechanical ventilation in mean days 7.67±6.24 had statistically significant SNHL compared to the lesser duration of mechanical ventilation (p<0.001). Two-stage DPOAEdone prior to AABR is helpful in the early detection of hearing loss.

Various aspects of hearing loss in newborns: A narrative review.

Hearing loss is considered the most common birth defect. The estimated prevalence of moderate and severe hearing loss in a normal newborn is 0.1%-0.3%, while the prevalence is 2%-4% in newborns admitted to the newborn intensive care unit. Neonatal hearing loss can be congenital (syndromic or non-syndromic) or acquired such as ototoxicity. In addition, the types of hearing loss can be conductive, sensorineural, or mixed. Hearing is vital for the acquisition of language and learning. Therefore, early detection and prompt treatment are of utmost importance in preventing the unwanted sequel of hearing loss. The hearing screening program is mandatory in many nations, especially for high-risk newborns. An automated auditory brainstem response test is used as a screening tool in newborns admitted to the newborn intensive care unit. Moreover, genetic testing and screening for cytomegalovirus in newborns are essential in identifying the cause of hearing loss, particularly, mild and delayed onset types of hearing loss. We aimed to update the knowledge on the various aspects of hearing loss in newborns with regard to the epidemiology, risk factors, causes, screening program, investigations, and different modalities of treatment.

Frequency of Acid-Base Derangements Among the Neonates Admitted to the Intensive Care Unit

Background: Every year deranged acid-base physiology drives admission to a critical care arena for a vast number of neonates. The neonatal intensive care unit is a fundamental sector for the survival of high-risk newborns. The acid-base disorder must always be considered in the clinical setting. The clinician should, in most cases, be able to predict the type of acid-base imbalance before the blood gas is available. Arterial blood gases (ABG-s) are the gold standard for assessing the adequacy of oxygen delivery, ventilation, and pH. This study aimed to assess the frequency of acid-base derangements among neonates admitted to the intensive care unit. Material &amp; Methods: This was an observational cohort study that was conducted in the Neonatal Intensive Care Unit (I.C.U.) of Dhaka Shishu Hospital, Dhaka, Bangladesh during the period from October 2009 to September 2010. In total 230 neonates admitted to the Neonatal Intensive Care Unit, after fulfilling the inclusion criteria were enrolled in this study as study subjects. For each baby, a detailed history was recorded in a questionnaire form (enclosed herewith) from the mother or other caregiver. It was filled up by the researcher himself containing history (including antenatal history), physical examinations and laboratory findings. Arterial blood gas analysis was done (in a clinical biochemistry laboratory using an automatic analyzer machine) for each neonate at admission and that report was recorded for this study. Results: Among the total study subjects, 127 newborn babies (55.2%) had acid-base imbalances. Mixed acidosis prevailed in the highest frequency (23.9%) Then metabolic acidosis cases were at 17.8% and respiratory acidosis was at 13.9%. Metabolic alkalosis and respiratory alkalosis were absent. Normal blood gas was observed in 44.3% of newborns. All the neonates with pH &lt;7 were dead. After Chi-Square analysis (at df=1), we found a highly significant correlation between mortality outcome with pH &lt;7.35, CO2 &gt;45, HCO3 &lt; 22 mol/l and Base deficit &gt;-10. All modalities of acid-base imbalances were significantly associated with mortality. Conclusion: In this study, a significant number of neonates who were admitted to the intensive care unit, can develop acid-base derangement. Mixed acidosis was found in the highest frequency. Metabolic, respiratory and mixed acidosis all has a significant correlation with death in a NICU. Metabolic alkalosis and respiratory alkalosis were found absent at admission.

Referral rate and false-positive rates in a hearing screening program among high-risk newborns.

More studies exploring referral rates and false-positive rates are needed to make hearing screening programs in newborns better and cost-effective. Our aim was to study the referral and false-positivity rates among high-risk newborns in our hearing screening program and to analyze the factors potentially associated with false-positive hearing screening test results. A retrospective cohort study was done among the newborns hospitalized at a university hospital from January 2009 to December 2014 that underwent hearing screening with a two-staged AABR screening protocol. Referral rates and false-positivity rates were calculated and possible risk factors for false-positivity were analyzed. 4512 newborns were screened for hearing loss in the neonatology department. The referral rate for the two-staged AABR-only screening was 3.8% with false-positivity being 2.9%. Our study showed that the higher the birthweight or gestational ageof the newborn, the lower the odds of the hearingscreening resultsbeing false-positive, and the higher the chronological age of the infant at the time of screening, the higher the odds of the resultsbeing false-positive. Our study did not show a clear association between the mode of delivery or gender and false-positivity. Among high-risk infants, prematurity and low-birthweight increased the rate of false-positivity in the hearing screening, and the chronological age at the time of the test seems to be significantly associated with false-positivity.

Expert nurses’ perceived parenting difficulties in Neonatal Intensive Care unit: A qualitative inductive study

PurposeThe birth of a high-risk newborn has significant psychosocial impacts on the family. Parents often experience difficulties in parenting after discharge. This study aimed to clarify the phenomena NICU expert nurses perceived and practiced during nursing care regarding concerns for parenting based on their focus and consciousness. Design and methodsThis qualitative descriptive study involved semi-structured interviews with six nurses (an average of 13.8 years of NICU nursing experience). Participants were asked to describe cases in which they provided nursing practices to parents with hospitalized children because they were concerned about their parenting. Fifteen cases with positive outcomes were inductively analyzed. ResultsFour main types of phenomena were observed: Adaptation to the parenting role, capacity of parenting including the parenting environment, readiness for parenthood, and an environment that nurtures parental confidence. Some cases involved more than one phenomenon. ConclusionsThe phenomenon wherein expert nurses anticipated the growing difficulties in parenting was found in interactions with parents of hospitalized children and in making them aware of their experiences. Clarifying their clinical reasoning and practice processes and the factors that enabled them may improve nurses’ practice skills and the well-being of children and families. Practice implicationsThe results may contribute to identifying parents who need careful support to achieve secure childcare and create a supportive environment for parents and children.

Impact of unplanned pregnancy on neonatal outcomes: findings of new high-risk newborns in Peru.

Unplanned pregnancy is a significant public health problem, especially in low- to middle-income countries. The objective of this study was to determine the neonatal outcomes associated with unplanned pregnancy in a public hospital in southern Peru. A cross-sectional analytical study was conducted from June to August 2021 among 306 mothers and their newborns selected by convenience sampling. After obtaining informed consent, mothers were surveyed during their postpartum hospitalization about their pregnancy intentions. Unintended pregnancy was considered when it was mistimed or unwanted. Neonatal outcomes were assessed by reviewing medical records prior to discharge, evaluating the presence of low birth weight, insufficient birth weight, prematurity, respiratory distress syndrome, sepsis and neonatal mortality. Association was measured in terms of prevalence ratio (PR) and beta coefficient and respective 95% CIs, crude and adjusted for variables that obtained a value of p<0.20 in the crude model (maternal age, education and parity). The overall unplanned pregnancies rate was 65%, of which 40.5% were mistimed pregnancies and 24.5% unwanted pregnancies. Unplanned and mistimed pregnancies were significantly associated with insufficient birth weight [adjusted prevalence ratio (aPR)=2.14; 95% CI 1.01 to 4.56 and aPR=2.43; 95% CI 1.09 to 5.39, respectively] and unwanted pregnancies were significantly associated with preterm birth (aPR=3.49; 95% CI 1.01 to 12.11). Furthermore, adjusted analysis showed that birth weight and gestational age were lower in unplanned, mistimed and unwanted pregnancies. Unplanned pregnancy was associated with lower birth weight and shorter gestational age of newborns. These data collected in a public hospital in a developing country may have significant implications today. If pregnancy intention is not included as a neonatal risk factor, insufficient birth weight and preterm birth could increase because a higher proportion of births will be unplanned.

Selective fundus screening for high-risk newborns: a realistic move in the Chinese mainland

Owing to the popularization of fundus screening for high-risk prematurity promoted by the state, the prevention and treatment of retinopathy of prematurity (ROP) in China has achieved remarkable results in recent years. Accordingly, the applicable population scope for newborn fundus screening is under heated discussion. Is it better to screen for all neonates or selective high-risk newborns, who meet the national ROP guidelines, have a history of familial or/and hereditary eye diseases or a systemic disease related to the eye after birth, or show an abnormal eye appearance or suspicious eye diseases in the primary care examination? Despite the advantages of general screening in detecting and treating some malignant eye diseases in a timely manner, the conditions for carrying out general newborn screening are not mature, and there are certain risks in the fundus examination of children. This article points out that the rational use of existing scarce medical resources to carry out selective fundus screening for newborns with high risks of eye diseases is practical in clinical work.

New approaches to screening and management of neonatal hypoglycemia based on improved understanding of the molecular mechanism of hypoglycemia.

For the past 70 years, controversy about hypoglycemia in newborn infants has focused on a numerical "definition of neonatal hypoglycemia", without regard to its mechanism. This ignores the purpose of screening newborns for hypoglycemia, which is to identify those with pathological forms of hypoglycemia and to prevent hypoglycemic brain injury. Recent clinical and basic research indicates that the three major forms of neonatal hypoglycemia are caused by hyperinsulinism (recognizing also that other rare hormonal or metabolic conditions may also present during this time frame). These include transitional hypoglycemia, which affects all normal newborns in the first few days after birth; perinatal stress-induced hypoglycemia in high-risk newborns, which afflicts ∼1 in 1,200 newborns; and genetic forms of congenital hyperinsulinism which afflict ∼1 in 10,000-40,000 newborns. (1) Transitional hyperinsulinism in normal newborns reflects persistence of the low glucose threshold for insulin secretion during fetal life into the first few postnatal days. Recent data indicate that the underlying mechanism is decreased trafficking of ATP-sensitive potassium channels to the beta-cell plasma membrane, likely a result of the hypoxemic state of fetal life. (2) Perinatal stress-induced hyperinsulinism in high-risk infants appears to reflect an exaggeration of this normal low fetal glucose threshold for insulin release due to more severe and prolonged exposure to perinatal hypoxemia. (3) Genetic hyperinsulinism, in contrast, reflects permanent genetic defects in various steps controlling beta-cell insulin release, such as inactivating mutations of the K ATP-channel genes. The purpose of this report is to review our current knowledge of these three major forms of neonatal hyperinsulinism as a foundation for the diagnosis and management of hypoglycemia in newborn infants. This includes selection of appropriate interventions based on underlying disease mechanism; combined monitoring of both plasma glucose and ketone levels to improve screening for infants with persistent forms of hypoglycemia; and ultimately to ensure that infants at risk of persistent hyperinsulinemic hypoglycemia are recognized prior to discharge from the nursery.

Using Machine Learning to Develop a Predictive Model of Infant Hypoglycemia Based on Maternal and Infant Variables in an Electronic Health Record

All newborns experience low blood glucose levels when they first initiate carbohydrate metabolism. Some levels remain low, with potential seizures and severe brain injury. Predicting newborns at higher risk is clinically useful because newborns can have their blood sugar raised with breastfeeding, donor milk, formula, or oral dextrose gels. Additionally, informing parents of this higher risk can enhance shared decision-making in the first 48 hours after birth. To address this, we propose three predictive models using binary logistic regression for newborns receiving treatment with oral dextrose gels for hypoglycemia. The first is a parsimonious model, where a high-risk newborn's first blood glucose value is highly predictive of requiring an oral dextrose gel treatment. The second model can be used earlier in the clinical workflow. It is based on the most predictive variables that are also electronically available for all newborns and do not change much in the electronic health record. The third model explores the most predictive variables based on a conceptual model of factors associated with health disparities. These three models are informed from insights gleaned by an exploratory analysis of alternative outcome measures, variables, and threshold cutoffs using a standard heuristic of greedily finding the highest average difference for records on both sides of partitions. We discuss how the dynamics of when data are available during a hospital stay in the postnatal care unit for all patients impact the selection of useful variables for electronically-based decision support. We plan to modify handouts for postnatal care nurses that detail treatment guidance and support shared decision-making. We plan to embed stratified guidance, recommended scripts for high and low-risk cohorts, orientation materials for float and junior nurses, and patient-facing educational materials.

Fecal Calprotectin Levels Dynamics in Newborns with High-Risk of Necrotizing Enterocolitis

Background. Necrotizing enterocolitis (NEC) is severe gastrointestinal disease in newborns, its early clinical symptoms are nonspecific. Fecal сalprotectin (Cp) is considered as one of the early biomarkers of NEC, thus, its use in newborns is poorly known.Objective. The aim of the study is to evaluate clinical significance of fecal Cp measuring as an early NEC marker in newborns. Methods. The prospective cohort observational study included high-risk newborns (gestational age (GA) ˂ 33 weeks and/or body weight ˂ 1500 g) and moderate risk newborns (GV≥ 33 weeks at suspicion on NEC) of NEC admitted to the neonatal intensive care unit on the 1st day of life. The Cp level was studied via immune colorimetric method on the 3rd and 7th days of life in high-risk children and in all children at NEC manifestation. All patients were divided into 2 main subgroups after the end of the follow-up period: newborns with developed NEC (a) and children without NEC (b). Obtained Cp values were compared between these subgroups.Results. There were no statistically significant differences in Cp levels at the 3rd and 7th days of life in the high-risk group of children with NEC and without NEC. However, it was noted that children without NEC showed a decrease in Cp levels on the 7th day, while children with NEC manifestation, indeed, had increased levels. Cp levels did not differ in the moderate risk group.Conclusion. Single measurement of Cp level in newborns of any GA is uninformative towards the NEC prognosis and diagnosis. However, evaluation of the Cp level dynamics at the 7th day of life compared to the 3rd day of life may be considered as a promising non-invasive method for prognosis of NEC manifestation in premature infants (GA&lt;33 weeks).

Developmental outcome of neonatal intensive care unit graduates born in tertiary care hospital in South India

Background: With the advancement in technology and advances in perinatal care, survival rates of high risk newborns have improve. Despite the reduction in neonatal mortality, chronic morbidities and adverse outcomes have not declined. These include cerebral palsy, cognitive delay, visual and auditory deficits signifying the need for regular monitoring of growth and development. Methods: Retrospective and prospective cohort study in a tertiary care centre in South India. Study duration of one year. Retrospective analysis of data of 190 high risk newborns admitted in NICU for more than 48 hours during the period 2012-2014. Neurodevelopmental outcome of these high-risk newborns at the age of 8-10 years. These were contacted and followed up for clinical assessment including motor and neurological function, visiomotor integrative skills, academic achievement, language, executive function, behavioral issues and child behavioral checklist applied. Findings described in simple descriptive manner. Results: In this study of 190 babies,139 babies were followed up for clinical assessment at the age of 8-10 years. From the follow up, 7.2% were diagnosed to have seizure disorder during childhood. 18.7% had hyperactive airway disease during childhood. 9.8% had academic problems, 5.8% had motor abnormalities, 2.9% had vision abnormalities requiring glasses from early childhood, 4.3% had gait abnormalities, 4.9% had speech related difficulties,17.3% had behavioral issues including excessive anxiety, withdrawal, aggressiveness. 1.2% had sleep problems, 21.6% babies had features of attention deficit hyperactivity disorder, 2.9% had features related to autism. Conclusions: Neonatal period is a critical period for proper neurodevelopment, having impact on child development. Babies with difficulties during transition period had higher immediate as well as long term morbidities. Long term morbidities included hyperactive airway disease/asthma, seizure disorder, academic problems, motor and gait abnormalities, behavioural abnormalities in childhood.

Roles and reported practices of paediatricians in the early identification and monitoring of hearing impairment in high-risk newborns and infants.

The paediatrician is often the first professional who provides care for the infant and their families, hence having a vital role in the early identification and intervention of hearing impairment. This study aimed to identify the role and reported practices of paediatricians in the early identification and monitoring of hearing impairment in high-risk newborns and infants. The sample comprised 30 paediatricians in South Africa. Data were collected by means of an online survey and analysed using descriptive statistics. Variability was noted in the early identification protocols, with most participants conducting objective measures. Although most participants refer newborns and infants for audiological evaluation when hearing impairment is suspected, there is variability with regard to the age at which they are referred. Approximately 98% of participants believe that they form part of the multidisciplinary team; however, only 69% reported that they have actually been part of a multidisciplinary team. Paediatricians had sufficient knowledge regarding the assessment of hearing impairment and their role in the early hearing detection and intervention programme. There is however a need for information sharing regarding appropriate hearing screening measures.

Establishment and evaluation of nomogram for predicting intraventricular hemorrhage in neonatal acute respiratory distress syndrome

BackgroundIntraventricular hemorrhage (IVH) is the most common type of brain injury in newborns, especially in newborns with Neonatal acute respiratory distress syndrome (ARDS). IVH can cause brain parenchyma damage and long-term neurological sequelae in children. Early identification and prevention of sequelae are essential. This study aims to establish a predictive nomogram for the early prediction of IVH in newborns with ARDS.MethodsFrom 2019 to 2021, we collected data from 222 infants diagnosed with ARDS in the Department of Neonatology, First Affiliated Hospital of Xinjiang Medical University. Infants have been randomly assigned to the training set (n = 161) or the validation set (n = 61) at a ratio of 7:3. Variables were screened using the Least Absolute Contract and Selection Operator (LASSO) regression to create a risk model for IVH in infants with ARDS. The variables chosen in the LASSO regression model were used to establish the prediction model using multivariate logistic regression analysis.ResultsWe recognized 4 variables as independent risk factors for IVH in newborns with ARDS via LASSO analysis, consisting of premature rupture of membranes (PROM), pulmonary surfactant (PS) dosage, PH1 and Arterial partial pressure of oxygen (PaO21). The C-Index for this dataset is 0.868 (95% CI: 0.837–0.940) and the C index in bootstrap verification is 0.852 respectively. The analysis of the decision curve shows that the model can significantly improve clinical efficiency in predicting IVH. We also provide a website based on the model and open it to users for free, so that the model can be better applied to clinical practice.ConclusionIn conclusion, the nomogram based on 4 factors shows good identification, calibration and clinical practicability. Our nomographs can help clinicians make clinical decisions, screen high-risk ARDS newborns, and facilitate early identification and management of IVH patients.

Four years of surveillance data on healthcare-associated infections in high-risk newborns

Objective: Healthcare-associated infections (HAIs) are a major issue in neonatal intensive care units (NICUs). The characteristics of HAIs and the distribution of pathogens might also vary. HAI surveillance is important for infection control to determine HAI rates and pathogen characteristics. The purpose of this study was to assess the rates of HAIs, distribution of HAI types, characteristics of the pathogens, and antibiotic susceptibility in the first four years of a newly opened NICU. Method: In the NICU of Marmara University Pendik Training and Research Hospital, the infection control team identified HAIs and recorded the National Hospital Infection Surveillance Network in accordance with the standards of the Centers for Disease Control and Prevention throughout the period of four years after the unit’s opening. All patients in the first four years of the NICU were included in the study. The capacity of the NICU is 16 incubators and the average nurse/neonate ratio was 1/3 in this period. Results: During the 4-year study period, 1301 patients were hospitalized in the NICU and 378 HAIs were detected. The overall HAI rate was 29.1% and the density was 21.8 per 1000 patient days. Neonatal groups with birth weights of 750 grams and 751–1000 grams had the highest rates and incidence density of HAIs. The most common HAI pathogens were Klebsiella spp. (27.8%), Staphylococcus spp. (26.2%), Acinetobacter baumannii (5.8%), and Escherichia coli (5.8%). Conclusion: The risk of HAIs was found to be higher in neonates with a birth weight &lt;1000 grams. In places where HAI rates are high such as NICUs, analyzing the characteristics of HAIs with active surveillance data is an essential component of infection control. This could enhance patient care and increase the survival of preterm infants with low birth weight.

Comparison of Hearing Impairment among Healthy and High-risk Neonates at a Tertiary Care Hospital, Rajasthan, India: A Cross-sectional Study

Introduction: Hearing impairment is caused by damage in the inner ear (can be even birth defect), ear infection, ruptured eardrum and so on. It can be prevented using early detection thus, helps in avoiding severe psychosocial, educational, and linguistic repercussions. Infants, who are not diagnosed of hearing impairment before six months of age, will have delays in speech and language development. Aim: To determine the prevalence of hearing impairment in highrisk neonates and to establish the fact that, these neonates have higher prevalence of hearing impairment as compared to normal population. Materials and Methods: A cross-sectional study was conducted in the Department of Paediatrics at Jawaharlal Nehru Medical College and Hospital, Ajmer, Rajasthan, India. The duration of the study was six months, from December 2012 to May 2013. A total of 500 babies including 297 normal and 203 high-risk babies were enrolled into the study. All the neonates were screened using Behavioural Observation Audiometry (BOA) and Distortion Product Oto-acoustic Emission (DPOAE) preferably within three days of life. Those, who failed under this test, underwent for Brain stem Evoked Response Audiometry (BERA). Data was collected in the Microsoft Excel and analysis done by Statistical Package for Social Sciences (SPSS) version 23.0. Results: The mean age of the newborns on admission, was 3.86±4.25 days and the mean weight was 2560±510 g. Out of 500 newborns screened, 58 babies had abnormal results with the first screening test. When these 58 babies subjected to BERA, eight babies showed Hearing Loss (HL). Sepsis, Neonatal Intensive Care Unit (NICU) stay &gt;5 days and use of aminoglycosides &gt;7 days were the important risk factors associated with hearing impairment. Prevalence of hearing impairment in the present study was came out to be 16/1000. This finding was statistically significant with p-value&lt;0.05. Conclusion: There was high prevalence of hearing impairment in high-risk newborns, majority of which were bilateral. The authors recommend multistage screening in all newborns at birth or within month’s time at all level of healthcare facility. Newborns with sepsis, NICU stay &gt;5 days and use of aminoglycosides &gt;7 days should have mandatory audiologic evaluation at discharge.

First-tier next-generation sequencing for newborn screening: An important role for biochemical second-tier testing

There is discussion of expanding newborn screening (NBS) through the use of genomic sequence data; yet, challenges remain in the interpretation of DNA variants. Population-level DNA variant databases are available, and it is possible to estimate the number of newborns who would be flagged as having a risk for a genetic disease (including rare variants of unknown significance, VUS) via next-generation sequencing (NGS) positive. Estimates of the number of newborns screened as NGS screen positive for monogenic recessive diseases were obtained by analysis of the Genome Aggregation Database. For a collection of diseases for which there is interest in NBS, we provided 2 estimates for the expected number of newborns screened as NGS positive. For a set of lysosomal storage diseases, we estimated that 100 to approximately 600 NGS screen positives would be found per disease per year in a large NBS laboratory (California), and this figure may be expected to rise to a limit of about 1000 if we account for the fact that the Genome Aggregation Database (gnomAD) does not contain all worldwide variants. The number of positives would drop 2.5- to 10-fold if the 10 VUS with highest allele frequency were biochemically annotated as benign. It is proposed that a second-tier biochemical assay using the same dried blood spot could be carried out as a filter and as part of NBS to reduce the number of high-risk NGS positive newborns to a manageable number.

Perinatal mortality following perinatal asphyxia &amp; birth environment: Case-control study

Perinatal asphyxia (PA) is a major health problem, responsible for high mortality and a wide range of morbidity. Several factors play a part in the occurrence of perinatal mortality during asphyxia. The aim of this work was to identify factors predictive of perinatal mortality following PA, using an unmatched case-control study. Thus, 31 cases and 126 controls were identified with a total of 157 newborns suffering from PA. It was carried out during April 1 to June 30, 2022, at the Mohammed VI University Hospital in Marrakech. The socio-demographic, clinical, and biological data of the newborns were collected using an evaluation grid. In this series, the sex ratio was 0.96 and the case-fatality rate 20%. The results showed that the factors showing a statistically significant association in the genesis of mortality in PA cases were : intrauterine growth retardation [(ORA= 4711,799), 95%, IC : ( 48,964, 453416,766)] ; maternal history [ (ORA =31,876, 95%,CI : (1,346;755,149)] ; Apgar index after 5 min less than or equal to 3: [(ORA=139,75), 95%, CI : (16,523 ; 1182,01)]; and congenital malformations : [(ORA=241,435), 95%, CI : ( 6,044 ; 9644,748)]. Consequently, addressing these factors is crucial to identify high-risk newborns at an early stage and to implement appropriate measures. The goal is to eliminate avoidable morbidity and disability.

Impact of the COVID-19 Pandemic on Neonatal Nursing Practicum and Extended Reality Simulation Training Needs: A Descriptive and Cross-Sectional Study.

This study investigated the neonatal intensive care unit (NICU) clinical practicum status during the COVID-19 pandemic and the need for extended reality (XR)-based training for neonatal care. A structured questionnaire was distributed to 132 prelicensing nursing students. Data were analyzed using importance-performance analysis and Borich needs analysis. Students wanted to use XR to learn about treating high-risk preterm infants. COVID-19 limited clinical training in NICUs, and most students preferred training in XR programs to improve their nursing competency for neonates. There is a large demand for nursing skills concerning high-risk newborns and hands-off training.

The single pregnancy predicting model of 1 minute Apgar score less than 7 after preterm birth: A retrospective study.

Preterm delivery is greatly associated with perinatal mortality and morbidity, while there is no objective way to identify high-risk newborns currently. This study aimed at discovering the risk factor for Apgar score less than 7 at 1 minute of preterm neonates born with vaginal delivery. A retrospective study was performed in single pregnancy women with a vaginal delivery before 37 weeks of gestation. All the preterm infants were categorized into three types: very preterm birth (28 to 32 weeks), moderate preterm birth (32 to 34 weeks) and late preterm birth (34 to 37 weeks). Risk factors were identified through logistic regression analysis in every category of newborns mentioned above. And the receiver operating characteristic analysis was used in continuous variables to determine the best threshold of the outcome. On the basis of the selected factors, the predicting models are created and its prognosticating ability is compared by the area under the curve. A nomogram was established for the proved best model. A total of 981 cases were investigated, of whom 55 were found with 1 min Apgar scores less than 7. The nomogram was set for the predicting model with larger area under the receiver operating characteristic curve, of which is 0.742(95% confidence interval = 0.670-0.805) in very preterm birth, with the variables of first and second labor stage(> = 1.6 hours), birthweight and MgSO4(magnesium sulfate), and is 0.807(95% confidence interval = 0.776-0.837) in late preterm birth, with the variables of second labor stage(> = 1.23 hours), birthweight, a history of previous cesarean delivery, fetal distress and placental abruption. The combination of first and second labor stage, newborn weight and MgSO4 use can predict 74.2% of 1 minute Apgar score < 7 in very preterm neonates. And 80.7% high-risk infants can be identified when second labor stage, newborn weight, VBAC (vaginal birth after cesarean) and the occur of placental abruption and fetal distress were combined in the predicting model for late preterm birth. These predicting models would bring out great assistance towards obstetricians and reduce unnecessary adverse fetal outcomes.

Perfil de morbidade no primeiro ano de vida entre recém-nascidos de alto risco

Introduction: Care for extremely premature newborns has provided important results in the survival of these children. Objective: To characterize the morbidity profile in the first year of life among high-risk newborns. Materials and Method: This is an exploratory research carried out at the follow-up clinic for high-risk newborns in the north of Minas Gerais. Data collection referred to admissions in the period from March 2014 to April 2015. The instrument included characteristics: demographic, social, pregnancy and delivery conditions, postpartum complications and health conditions of children monitored during the first year of life. Descriptive statistical analysis and the chisquare test were performed, assuming a significance level of 5% to compare the distribution of morbidities by weight range. Results: A total of 282 newborns participated in this study, 53.9% of whom were male. Among the mothers, 58.2% were multiparous and 35.8% were hypertensive. Regarding birth weight, 59.6% of newborns monitored weighed less than 1500 grams. The main morbidities identified in the first year of life were delayed neuro-psycho-motor development, upper airway infections, neurological disorders and chronic respiratory conditions. Statistically significant differences were recorded for delayed neuro-psycho-motor development (p&lt;0.001), neurological complications (p=0.008) and episodes of diarrhea (p=0.047), between birth weight ranges. Conclusion: Outpatient care for high-risk premature newborns contributes to the identification and prevention of recurrent diseases in this population.
