A Flipped Classroom Pilot in Neonatal Mechanical Ventilation

Background

Pediatric residents frequently manage critically ill neonates but have limited systematic training in mechanical ventilation (MV). Competing demands, varying learner levels, and topic complexity contribute to inconsistent education. A blended learning approach may be ideally suited to achieve meaningful learning but has not been described for this topic and learner.

Objective

To design, implement, and evaluate a flipped classroom for pediatric residents in neonatal MV.

Methods

We used Kern's six-step framework for curricular development to create a flipped classroom curriculum in neonatal MV. Individual prework included interaction with six prerecorded animated whiteboard videos, while in-person learning occurred in small groups at the bedside of a ventilated infant. A mixed-methods evaluation included surveys, quantitative knowledge test scores (before, immediately after, and six months after course completion), and qualitative analysis of participant focus groups.

Results

Twenty-six learners participated in the curriculum. Mean knowledge test scores rose and were sustained after course completion (51% baseline, 82% immediate posttest, 90% retention; P < 0.001). Learners identified various design elements, technology affordances, and instructor factors as meaningful, and they identified unexpected impacts of the curriculum beyond knowledge acquisition, including effects on professional identities, interdisciplinary communication skills, and contribution to the culture of safety.

Conclusion

This curriculum aligned with resident roles, was meaningful to learners, and led to long-term increases in knowledge scores and access to quality education; flipped classroom design using meaningful learning theory and leveraging animated whiteboard technology may be a useful strategy for other highly complex topics in graduate medical education.

Critical Illness-Related Corticosteroid Insufficiency (CIRCI) After Pediatric Cardiac Surgery

Although current studies do not support the routine use of corticosteroids after cardiopulmonary bypass in pediatric patients, there is incomplete understanding of the potential hemodynamic contribution of postoperative critical illness-related corticosteroid insufficiency in the intensive care unit. By reviewing the available studies and underlying pathophysiology of these phenomena in critically ill neonates, we can identify a subset of patients that may benefit from optimal diagnosis and treatment of receiving postoperative steroids. A suggested algorithm used at our institution is provided as a guideline for treatment of this high-risk population.

Standardizing Minimally Invasive Tissue Sampling of Postmortem Brain Using Bard Monopty Needle in Newborns with Neurological Injury

INTRODUCTION

Minimally invasive tissue sampling of the brain in newborns using the Bard Monopty needle helps to diagnose various neurological conditions by obtaining relevant brain cores. We designed a modified procedure to provide maximum diagnostic utility in brain tissue biopsies.

METHOD

Twenty newborns underwent postmortem minimally invasive tissue sampling of the brain through the anterior fontanelle and posterior approach, using the engraved lines on the needle labeled from mark 0 to 13. The cores were correlated with conventional autopsy findings.

RESULTS

Meninges were best obtained at marks 0 and 1 from the anterior fontanelle and mark 1 from posterior fontenelle in 85% of cases. Periventricular brain parenchyma was best obtained from mark 3 and mark 1 from anterior and posterior fontanel, respectively in 90% cases. The sampling success in obtaining brain cores was 100%.

DISCUSSION

This modified technique increases the yield of meninges and brain tissue in newborns and aids in diagnosis.

Spontaneous Partial Regression of Fetal Lung Interstitial Tumor With A2M::ALK Rearrangement in a Neonate

The differential diagnosis for neonatal primary lung masses includes developmental anomalies and congenital lung tumors. Fetal lung interstitial tumor (FLIT) is a rare benign mesenchymal lesion which presents either antenatally or within the first 3 months of age. FLIT is a circumscribed solid-cystic mass which histologically resembles the fetal lung during the canalicular stage at 20-24 weeks of gestation. It is composed of immature mesenchymal cells expanding the interstitium and irregular airspace-like structures. Of all published cases, only 1 identified an α2-macroglobulin (A2M)::anaplastic lymphoma kinase (ALK) fusion and all cases underwent surgical resection in the neonatal or infancy period. We present the second case of FLIT with an A2M::ALK fusion diagnosed postnatally in a neonate which partially regressed spontaneously during conservative management with interim resection at 39 months of age, and provide a review of the literature.

Albumin and C-reactive protein as diagnostic markers for neonatal sepsis: a retrospective study

OBJECTIVE

To assess the applicability of albumin (ALB) and C-reactive protein (CRP) concentrations in the diagnosis of sepsis in neonates on the day of admission, and to help with early identification and intervention in the development of sepsis.

METHODS

This retrospective study included all neonates who were admitted to the neonatal intensive care unit from January 2020 to June 2023. We studied 160 full-term neonates, including 80 with sepsis and 80 healthy controls. A multivariate analysis was conducted to evaluate the associations between ALB, CRP, and sepsis.

RESULTS

CRP concentrations were significantly higher in neonates with sepsis than in controls (26.5 ± 8.6  vs. 3.6 ± 1.2 ng/L). At a cut-off point of 10.8 ng/L, CRP showed a sensitivity of 74.3% and a specificity of 80%. Moreover, ALB concentrations were significantly lower in neonates with sepsis than in controls (25.4 ± 2.5 g/L vs. 29.2 ± 2.6 g/L). At a cut-off point of 26.8, ALB showed a sensitivity of 75.6% and a specificity of 84.2%.

CONCLUSIONS

Our findings suggest that ALB and CRP concentrations on the first day of admission are different between neonates who do and those who do not develop sepsis. Higher CRP concentrations and lower ALB concentrations may indicate an increased risk of sepsis.

Clinical characteristics of preterm and term infants with Ureaplasma in gastric fluid

BACKGROUND

Ureaplasma spp. is an endemic microorganism that causes placental chorioamnionitis or preterm delivery in pregnant women, and the occurrence of bronchopulmonary dysplasia or intraventricular hemorrhaging in preterm infants after birth, although the pathogenicity of Ureaplasma remains controversial. The association between Ureaplasma exposure and the symptoms or outcomes of infected mothers or their infants born at term remains poorly understood. We investigated the clinical characteristics of preterm and term infants with or without Ureaplasma in their gastric fluid.

METHODS

Gastric fluid samples were collected from 47 newborns in the neonatal intensive-care unit immediately after birth and tested using multiplex polymerase chain reaction (PCR) assays targeting Ureaplasma spp., Ureaplasma parvum, and Ureaplasma urealyticum. The clinical findings and outcomes of the neonates and their mothers were retrospectively evaluated.

RESULTS

Ureaplasma spp. were detected in 9/47 samples (19%) by multiplex PCR assays. In all cases, the subspecies was U. parvum. The Ureaplasma-positive group had a significantly higher incidence of chorioamnionitis in utero than the Ureaplasma-negative group. Regarding preterm infants, the IgM levels in the Ureaplasma-positive group were significantly higher than in the Ureaplasma-negative group. In contrast, in term infants, the rates of a non-reassuring fetal status, a maternal fever, and maternal leukocyte counts and maternal C-reactive protein levels within five days before delivery in the Ureaplasma-positive group were significantly higher than those in the Ureaplasma-negative group. All three extremely-low-birth-weight infants with Ureaplasma developed bronchopulmonary dysplasia. The length of hospitalization in the Ureaplasma-positive group was almost same as that in the Ureaplasma-negative group for term infants.

CONCLUSION

Mothers or their fetuses with exposure to Ureaplasma expressed characteristic clinical features during pregnancy and after birth.

Christie, Atkins, Munch-Peterson (CAMP) Negative Listeria monocytogenes Meningitis in Neonates: Report of Two Cases

Listeria monocytogenes, a gram-positive bacillus and an intracellular pathogen, is an uncommon cause of illness in the general population. During pregnancy, a perinatal infection can lead to serious complications such as abortion, stillbirth, neonatal sepsis, and meningitis. We present two cases of neonatal meningitis caused by Christie, Atkins, Munch-Peterson (CAMP)-negative Listeria monocytogenes. In the first case, a seven-day-old female term neonate delivered vaginally, presented with high-grade fever and refusal to feed. In view of the suspected late-onset sepsis, a septic workup, including cerebrospinal fluid analysis, was conducted. CSF culture reports obtained showed a growth consistent with Listeria monocytogenes, which was CAMP test negative and susceptible to the penicillin group of drugs, cotrimoxazole, erythromycin, and meropenem. The isolate was identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and confirmed by 16S rRNA sequencing. The blood culture was sterile. At 48 hours of admission, the neonate clinically deteriorated with fluctuation in oxygen saturation below 95% at room air. Thus, she was electively intubated and connected to the mechanical ventilator with appropriate settings. The antibiotics were upgraded to meropenem from the empirical antibiotic therapy. The neonate showed clinical improvement within the next 24 hours of initiating antibiotics according to culture susceptibility and was gradually weaned from the mechanical ventilator to continuous positive airway pressure (CPAP). After 24 hours, she was able to maintain normal saturation at room air. In the second case, an 11-day-old low birth weight neonate, small for gestational age, was presented to the NICU with complaints of loose stools, fever, and refusal to feed for the past two days. In view of the suspected sepsis, relevant investigations were carried out while initiating empirical antibiotics IV piperacillin-tazobactam and IV amikacin for the neonate. Meanwhile, there was a dip in oxygen saturation noted on room air for the neonate and he/she was mechanically ventilated. The CSF culture grew Listeria monocytogenes,which was identified using MALDI-TOF MS and confirmed by 16S rRNA sequencing. The isolate tested negative for the CAMP test and was susceptible to ampicillin, penicillin, cotrimoxazole, erythromycin, and meropenem. The blood culture was sterile. The antibiotics were upgraded to meropenem from the empirical antibiotic therapy, the patient's condition improved, and the baby was eventually discharged.

The Prevalence and Associated Risk Factors for Neonatal Thrombocytopenia Among Newborns Admitted to the Neonatal Intensive Care Unit

Background Thrombocytopenia is the most prevalent hematological condition in neonates that develops in the neonatal intensive care unit (NICU). This set of illnesses is caused by either decreased platelet production due to placental insufficiency, increased platelet breakdown (consumption), or a combination of the two causes. Based on platelet count, it is defined as mild, moderate, or severe thrombocytopenia, with early and late onset. Purpose The purpose of this study is to determine the prevalence of thrombocytopenia and the factors that contribute to it in newborns hospitalized in the neonatal critical care unit at the Maternity and Children Hospital in Al Ahsa, Saudi Arabia. Methods This descriptive retrospective cross-sectional study was carried out at the NICU of the Maternity and Children Hospital in Al Ahsa, Saudi Arabia, over the span of one year (August 2022 to August 2023) among hospitalized neonates with thrombocytopenia. Thrombocytopenia is defined as a platelet count of 150,000 or less. These patients were monitored until they recovered or died. Results The inclusion criteria were met by a total of 242 newborns with thrombocytopenia. Half of the neonates (57%) were full-term, with Apgar scores greater than 5 at the first (84%) and fifth (93%) minutes, respectively. The great majority of individuals (84%) experienced early-onset thrombocytopenia of mild severity (62%) and were asymptomatic (93%). The majority of the cases resolved spontaneously, with only 21% requiring platelet transfusion. There was a significant relationship discovered between gestational age and the severity of thrombocytopenia, with very preterm infants having moderate to severe thrombocytopenia, as well as birth weight (p=0.001). Furthermore, neonates with severe thrombocytopenia had a considerably higher mortality rate (p=0.001). Conclusion The mortality and morbidity of newborns with perinatal risk for neonatal thrombocytopenia can be reduced with timely detection of the cause and development of thrombocytopenia, as well as adequate and early care.

Randomized Controlled Trial on the Effect of the Neonatal Nurse Navigator Program on Maternal Stress and Neonatal Cortisol Levels

OBJECTIVE

To assess the effect of the Neonatal Nurse Navigator Program (NNNP) compared to usual care on maternal stress and neonatal salivary cortisol level (SCL) in the NICU.

DESIGN

Randomized control trial.

SETTING

NICU in a tertiary health care hospital in Manipal, Udupi District, Karnataka, India.

PARTICIPANTS

Neonates between 34 and 36 weeks gestation and their mothers (N = 120 dyads).

METHODS

We used block randomization to assign dyads to the intervention or control group. We measured maternal stress using the Parental Stress Scale: Neonatal Intensive Care Unit, and we estimated neonatal stress by measuring SCLs within 24 hours of NICU admission and before discharge from the unit. We conducted a descriptive analysis on participant characteristics and reported maternal stress levels using means and standard deviations. We used the analysis of covariance change score test to determine the difference in maternal and neonatal stress levels between the intervention and control groups.

RESULTS

The NNNP group exhibited significantly lower maternal stress scores before discharge than the control group, and we observed reductions across all three subscales of the Parental Stress Scale: Neonatal Intensive Care Unit. Mean neonatal salivary cortisol levels were significantly lower in the interventional group than in the control group, F(1.117) = 24.03, 95% confidence interval [7.9, 18.6], p < .001.

CONCLUSION

Use of the NNNP reduced maternal stress SCLs in high-risk neonates by actively engaging mothers in the care of their neonates in the NICU. We recommend adoption of the NNNP model as a standard care policy in NICUs throughout India.

Synchronized cardioversion resolving refractory supraventricular tachycardia in a neonate: a case report with comprehensive analysis

Introduction and importance

Neonatal supraventricular tachycardia (SVT) poses unique challenges in diagnosis and management, with refractory cases requiring synchronized cardioversion being exceptionally rare. This case report explores the presentation and management of refractory SVT in a neonate, emphasizing the significance of sharing such clinical scenarios.

Case presentation

A 16-day-old neonate, born via emergency caesarean section, presented with respiratory distress, poor feeding, and vomiting. Initial diagnosis of SVT was made on the basis of electrocardiography (ECG) changes. Initial attempts with adenosine failed, leading to the recurrence of tachycardia. Despite amiodarone administration, the tachycardia persisted, prompting synchronized cardioversion. Post-cardioversion, the neonate was managed with oral medications, showing sustained improvement.

Clinical discussion

This case report highlights a neonate with refractory SVT, requiring synchronized cardioversion, presenting a rare and challenging scenario. The report addresses diagnostic challenges, treatment approaches, and potential mechanisms for refractory SVT, such as delayed presentation and resistance to adenosine. Emphasizing individualized care plans and vigilant monitoring, this report is a valuable resource for healthcare professionals, contributing to neonatal cardiology understanding and emphasizing the importance of early recognition and effective interventions. Ongoing follow-up and successful outcomes underscore the need for sustained management strategies.

Conclusion

This case report sheds light on the rarity of refractory SVT in neonates, emphasizing the complexities in diagnosis and management. Successful synchronized cardioversion and subsequent oral therapy highlight the need for a multifaceted approach in neonatal SVT cases. The implications for clinical practice underscore the importance of awareness and continued research in neonatal cardiology and emergency medicine.

Myths Pertaining to COVID-19 Vaccination in Pregnant Women Attending a Rural Tertiary Care Hospital

Background The outbreak of the COVID-19 pandemic led to the rise of various social issues apart from medical ones. Several myths regarding COVID-19 vaccination were found worldwide, and some of the common ones identified were abortions, birth defects, bad pregnancy outcomes such as abortions, ectopic pregnancy, risk of infertility, and irregular menstrual cycles. Although no scientific theories or data backed those myths, pregnancy was still omitted from trials for a long time as any drug/vaccine given during pregnancy may affect the fetus. Objective The objective of this study was to evaluate the vaccination status of pregnant women (PW) regarding COVID-19 and explore the factors influencing those who chose not to get the initial dose, second dose, or booster dose. Methodology A total of 747 PW were enrolled in the current study. Information related to sociodemographic data, clinical data, COVID-19 vaccine status, and rationale for choosing not to receive the COVID-19 vaccination was analyzed using a prestructured and validated Performa. Results The mean age and gestational age of the women enrolled for the study was 27.39 ± 3.75 years and 30.21 ± 7.30 weeks, respectively. The first dose of the COVID-19 vaccine was not received by 40 (5.4%) subjects, and the second dose was pending in 142 (19%) women, and none of them received booster dose. The prevalent cause for abstaining from receiving the COVID-19 vaccination was the fear of abortion in 179 (24%) subjects, followed by the fear of vaccine-related side effects in 142 (19%) subjects. There was a significant correlation between acceptance of COVID-19 vaccination and education and employment. Conclusion The present study indicated that most women have taken the COVID-19 vaccine before conception and that none received the first, second, or booster dose during pregnancy, even if it was due. Women need to be educated about the benefits of vaccination to enhance the compliance rate of COVID-19 vaccination and reduce COVID-19-related morbidity and mortality during pregnancy.

Rural Versus Urban Mothers' Microbiome Difference and Its Effect on Neonates: A Systematic Review

The growth and development of microorganisms are stimulated by external stimuli. Urbanization has changed the macroenvironment and individual microenvironmental factors such as smoking, alcohol, and diet, which can alter the microbiota and influence disease in the mother and child. However, the microbiome difference between rural and urban mothers and its effect on neonates have received little attention, as per sources; we have not found any systematic review. This review determined the microbiome difference between rural and urban mothers and its effect on neonates. Five studies selected based on inclusion/exclusion criteria were retrieved from PubMed, Scopus, and Embase databases, and evidence-based comparisons were made to establish the microbiome difference in rural and urban mothers and its effect on neonates. The study findings indicate that microbiome development in newborns is hindered by urbanization. Infants born to urban mothers have reduced microbial diversity, thereby having decreased protective immunity.

A Less Invasive Technique for Surfactant Administration in a Full-Term Newborn With Moderate Meconium Aspiration Syndrome

Meconium aspiration syndrome (MAS) presents significant challenges in neonatal care, particularly in the context of respiratory distress. This report explores the efficacy of administering surfactant through a less invasive surfactant administration (LISA) technique in a full-term neonate with MAS. Our case highlights the potential of this method in reducing the need for mechanical ventilation, drawing parallels with its established benefits in preterm neonates with respiratory distress syndrome. The successful application of LISA in this case suggests a promising avenue for managing MAS in full-term neonates, warranting further investigation.

The Finnegan Score for Neonatal Opioid Withdrawal Revisited With Routine Electronic Data: Retrospective Study

Background

The severity of neonatal abstinence syndrome (NAS) may be assessed with the Finnegan score (FS). Since the FS is laborious and subjective, alternative ways of assessment may improve quality of care.

Objective

In this pilot study, we examined associations between the FS and routine monitoring data obtained from the electronic health record system.

Methods

The study included 205 neonates with NAS after intrauterine (n=23) or postnatal opioid exposure (n=182). Routine monitoring data were analyzed at 60±10 minutes (t-1) and 120±10 minutes (t-2) before each FS assessment. Within each time period, the mean for each variable was calculated. Readings were also normalized to individual baseline data for each patient and parameter. Mixed effects models were used to assess the effect of different variables.

Results

Plots of vital parameters against the FS showed heavily scattered data. When controlling for several variables, the best-performing mixed effects model displayed significant effects of individual baseline-controlled mean heart rate (estimate 0.04, 95% CI 0.02-0.07) and arterial blood pressure (estimate 0.05, 95% CI 0.01-0.08) at t-1 with a goodness of fit (R2m) of 0.11.

Conclusions

Routine electronic data can be extracted and analyzed for their correlation with FS data. Mixed effects models show small but significant effects after normalizing vital parameters to individual baselines.

Comparison of High-Frequency Oscillatory Ventilators

BACKGROUND

The performance of high-frequency oscillatory ventilators (HFOV) differs by the waveform generation mode and circuit characteristics. Few studies have described the performance of piston-type HFOV. The present study aimed to compare the amplitude required to reach the target high-frequency tidal volume ([Formula: see text]); determine the relationship between the settings and actual pressure in amplitude or mean airway pressure ([Formula: see text]); and describe the interaction among compliance, frequency, and endotracheal tube (ETT) inner diameter in 4 HFOV models, including Humming X, Vue (a piston type ventilator commonly used in Japan), VN500 (a diaphragm type), and SLE5000 (a reverse jet type).

METHODS

The oscillatory ventilators were evaluated by using a 50-mL test lung with 0.5 and 1.0 mL/cm H2O compliance, [Formula: see text] of 10 cm H2O, frequency of 12 and 15 Hz, and ETT inner diameters 2.0, 2.5, and 3.5 mm. At each permutation of compliance, frequency, and ETT, the target high-frequency [Formula: see text] was increased from 0.5 to 3.0 mL. The change in [Formula: see text] from the ventilator (ventilator [Formula: see text]) to Y-piece (Y [Formula: see text]) and alveolar pressure (alveolar [Formula: see text]) and the change in amplitude from the ventilator (ventilator amplitude) to Y-piece (Y amplitude) and alveolar pressure (alveolar amplitude) were determined at high-frequency [Formula: see text] of 1.0 and 3.0 mL.

RESULTS

To achieve the target high-frequency [Formula: see text], the Humming X and Vue required a higher amplitude than did the SLE5000, but the maximum amplitude in the VN500 was unable to attain a larger high-frequency [Formula: see text]. Ventilator [Formula: see text] and alveolar pressure decreased at the Y-piece with the Humming X and Vue but increased with the SLE5000. The ventilator [Formula: see text] in the VN500 decreased remarkably at a frequency of 15 Hz. The ventilator amplitude in all 4 ventilators decreased while temporarily increasing at the Y-piece in the VN500.

CONCLUSIONS

The actual measured value, such as alveolar [Formula: see text] and high-frequency [Formula: see text], varied according to the type of HFOV system and the inner diameter of the ETT, even with identical settings. Clinicians should therefore determine the setting appropriate to each HFOV model.

Severe Cholestasis in Neonates with Hemolytic Disease of the Fetus and Newborn-A Case Report

Hemolytic disease of the fetus and newborn (HDFN) may cause severe cholestasis with direct bilirubin concentrations reaching up to 50 times the upper limit of normal. This case report describes twins whose highest direct bilirubin concentrations were 32.2 mg/dL and 50.2 mg/dL, with no significant signs of hepatic impairment. The index pregnancy was complicated by Rhesus factor immunization with anti-D antibodies present in maternal serum, which caused fetal anemia requiring intrauterine blood transfusions. Complementary tests demonstrated Rhesus D alloimmunization as the sole cause of cholestasis. To the best of our knowledge, this is the first study to describe such elevated direct bilirubin concentrations caused by HDFN.

The Babyccino: The Role of Caffeine in the Prevention of Acute Kidney Injury in Neonates-A Literature Review

Acute kidney injury (AKI) in neonates is associated with increased morbidity and mortality. Theophylline (a methylxanthine) has been shown to prevent neonatal AKI but is seldom used due to its unfavorable profile. Caffeine, another methylxanthine, is utilized ubiquitously to treat apnea of prematurity, but there are no randomized trials evaluating its efficacy in preventing neonatal AKI. This literature review aims to summarize the existing research pertaining to the relationship between caffeine and neonatal AKI. The review was conducted using Pubmed, Embase, Google Scholar, and Cochrane. Inclusion criteria incorporated empirical studies, being published in English, and being available electronically. All eight studies identified were included. Seven studies found caffeine-exposed premature neonates had lower rates of AKI than caffeine-unexposed neonates. Four found reduced AKI severity with caffeine exposure. One study included term neonates and did not find a difference in the AKI rate between caffeine-exposed and non-exposed babies. Limitations include exclusively observational studies, short study periods, heterogenous definitions of prematurity, and a lack of assessment of dose-effect relationships. In conclusion, premature neonates exposed to caffeine appear to have lower rates and potentially less severe AKI. Further research is needed before caffeine can be considered for use in the primary prevention of neonatal AKI.

Amelioration of oxygen-induced retinopathy in neonatal mice with fetal growth restriction

Introduction: With the aim of optimizing the balance of maintaining a safe oxygen saturation and reducing the risk of retinopathy of prematurity in human neonates with fetal growth restriction (FGR), the present study investigated the distinct effects of oxygen supplementation on the retinal neovasculature using a murine premature neonatal oxygen-induced retinopathy (OIR) model with or without fetal growth restriction. Methods: For comparison with normal birth-weight neonates, maternal low-protein diet-induced FGR neonates were subjected to fluctuating oxygen levels to generate oxygen-induced retinopathy. The retinal neovasculature was histologically evaluated, and comprehensive transcriptome analysis was conducted. Results: Compared to OIR neonates with normal birth weight, significant amelioration of the neovasculature, as indicated by decreases in the number of branch junctions, vascular distribution, maximal vascular radius and microaneurysm-like tufts, was observed in OIR mice with FGR. The results of retinal RNA-sequencing revealed downregulation of angiogenic factors that trigger pathological retinal neovascularization, such as the mitogen-activated protein kinase pathway and corresponding upstream signaling pathways in OIR mice with FGR. Conclusion: Our findings demonstrated that FGR neonates have a higher capacity for retinal oxygen stress, and the risk of OIR development is attenuated compared to that in mature neonates with normal birth weight.

Measurement of Head Circumference Using a Smartphone: Feasibility Cohort Study

BACKGROUND

Accurate head circumference (HC) measurement is essential when assessing neonates and infants. Tape measure HC measurements are prone to errors, particularly when performed by parents/guardians, due to individual differences in head shape, hair style and texture, subject cooperation, and examiner techniques, including tape measure placement and tautness. There is, therefore, the need for a more reliable method.

OBJECTIVE

The primary objective of this study was to evaluate the validity, reliability, and consistency of HC app measurement compared to the current standard of practice, serving as a proof-of-concept for use by health care professionals.

METHODS

We recruited infants attending the neurosurgery clinic, and parents/guardians were approached and consented to participate in the study. Along with the standard head circumference measurement, measurements were taken with the head circumference app (HC app) developed in-house, and we also collected baseline medical history and characteristics. For the statistical analysis, we used RStudio (version 4.1.1). In summary, we analyzed covariance and intraclass correlation coefficient (ICC) to compare the measurement's within-rater and interrater reliability. The F test was used to analyze the variance between measurements and the Bland-Altman agreement, t test, and correlation coefficients were used to compare the tape measurement to the measures taken by the HC app. We also used nonvalidated questionnaires to explore parental or guardians' experiences, assess their views on app utility, and collect feedback.

RESULTS

The total number of recruited patients was 37. Comparison between the app measurements and the measurements with a tape measure showed poor reliability (ICC=0.177) and wide within-app variations (ICC=0.341). The agreement between the measurements done by parents/guardians and the tape measurements done by the researcher was good (ICC=0.901). Parental/guardian feedback was overall very positive, with most of the parents/guardians reporting that the app was easy to use (n=31, 84%) and that they are happy to use the app in an unsupervised setting, provided that they are assured of the measurement quality.

CONCLUSIONS

We developed this project as a proof-of-concept study, and as such, the app has shown great potential to be used both in a clinical setting and by parents/guardians in their own homes.

A scoping review and narrative synthesis of neonatal skin injury severity scales

BACKGROUND

Mechanical force skin injuries are common for critical care patients, especially neonates. Currently, identification and severity assessments of injuries are dependent on clinical experience and/or utilization of severity tools. Compared with adults, neonates sustain skin injuries in different anatomical locations and have decreased layers of healthy tissue (from 0.9 to 1.2 mm) creating questions around direct application of adult injury severity scales reliant on visual assessment.

AIMS

The aim of this scoping review (ScR) was to investigate severity scales used to report hospital acquired skin injuries for neonates.

METHODS

This study utilized the 2015 Joanna Briggs Institute methodology for scoping reviews and is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews extension. PubMed, CINAHL, COCHRANE Central, Scopus, and the reference lists of included studies were searched for studies published between 2001 and 2023, that included severity scales use within neonatal population. Two authors independently identified studies for full review, data extraction, and quality assessment.

RESULTS

A systematic database search returned 1163 records. After full test review of 109 studies, 35 studies were included. A majority of studies included were cohort or action research and conducted in the United States of America. Most studies (57%, n = 20) reported skin injuries acquired throughout the body, 14 (40%) of the studies reported the nasal area alone and one study reported no anatomical location. A total of nine severity scales or combination of scales were utilized within studies (n = 31) and four studies did not report a scale. Various versions of scales from the National Pressure Ulcer Advisory Panel (n = 16), European Pressure Ulcer Advisory Panel (n = 8) or Neonatal Skin Condition Score (n = 4) were reported, compared with locally developed classifications/scales (n = 4). Scales were predominantly of ordinal grouping (74%, n = 26) or categorical assessment (14%, n = 5). Only one scale from 2004 was validated for neonates.

CONCLUSION

Neonatal skin injuries will continue to be reported subjectively until severity scales are consistently applied or other measurements are identified to support assessment. Additionally, without skin injury assessment uniformity, critical examination of effectiveness of skin care treatment practices will have subjective comparison. This review suggests there is a need for consistent skin assessment and severity scales that are valid for the neonatal population and their unique skin considerations.

The timing of antenatal care access for adolescent pregnancies in Cape Town, South Africa

BACKGROUND

 Late antenatal care (ANC)-seeking among pregnant adolescents threatens their health outcomes, and the health outcomes of their new-borns. South Africa has experienced a rapid increase in adolescent pregnancies during the COVID-19 pandemic, adding to the existing concerns around adolescent pregnancy care-seeking behaviour.

AIM

 The main aim of this study was to investigate the causes and covariates of late ANC access among adolescents in the Cape Town Metropole, South Africa.

SETTING

 Three public healthcare facilities in the Cape Town Metropole, 2018-2019.

METHODS

 A retrospective, cross-sectional study on ANC seeking behaviour was conducted, surveying 202 adolescents. Late attendance was defined as attending ≥ 3 months. For this study, adolescents were defined as women aged 16-18 years. The sample was restricted to adolescents who used public healthcare facilities or who did not attend at all. Data were analysed using univariate, bivariate and multivariate methods.

RESULTS

 A total of 50.8% (n = 99/195) of the pregnant adolescents in the sample had their first ANC visit 3 months. 14.9% (n = 29/195) did not attend at all. Major contributors to delayed care-seeking include poor pregnancy identification (n = 45/99, 45.5%), and a lack of information about ANC. Age, education, and alcohol consumption were significant predictors of delayed care-seeking.

CONCLUSION

 Delayed ANC attendance contributes to negative long-term health outcomes for pregnant adolescents and their new-borns. Improving access to pregnancy tests in the public sector could benefit adolescents with earlier pregnancy identification. Adolescents need to be made aware of their care seeking options.Contribution: There is evidence of long-term health impacts of late ANC attendance by pregnant adolescents, but there is an absence of evidence on the timing and barriers of late care-seeking behaviour. In this study, late ANC attendance among adolescents was associated with late pregnancy identification and poor knowledge of care options.

Ursodeoxycholic acid for preventing parenteral nutrition-associated cholestasis in neonates: A systematic review and meta-analysis

BACKGROUND

While ursodeoxycholic acid is used in treating parenteral nutrition-associated cholestasis (PNAC) in neonates, its role in prevention is unclear.

OBJECTIVES

In this systematic review and meta-analysis, we attempted to determine the role of ursodeoxycholic acid in preventing PNAC in neonates.

METHODS

PubMed, Embase, Cochrane Library, Scopus, and CINAHL databases were searched on September 16, 2023, for interventional studies comparing ursodeoxycholic acid with placebo.

RESULTS

Of the 6180 unique records identified, five studies were eligible for inclusion (three randomised and two nonrandomised). Evidence from randomised trials showed that ursodeoxycholic acid prophylaxis did not reduce cholestasis, mortality, sepsis, and necrotising enterocolitis. Ursodeoxycholic acid prophylaxis reduced feed intolerance (RR 0.23 (0.09, 0.64); 1 RCT, 102 neonates), peak conjugated bilirubin levels (MD -0.13 (-0.22, -0.04) mg/dL; 1 RCT, 102 neonates), and time to full enteral feeds (MD -2.7 (-5.09, -0.31) days; 2 RCTs, 76 neonates). There was no decrease in hospital stay and parenteral nutrition duration. Data from nonrandomised studies did not show benefit in any of the outcomes. The certainty of the evidence was low to very low.

CONCLUSION

Because of the very low-quality evidence and lack of evidence on critical outcomes, definitive conclusions could not be made on using ursodeoxycholic acid to prevent parenteral nutrition-associated cholestasis in neonates.

Phototherapy causing a purpuric eruption in a neonate

Neonatal jaundice is a frequent condition in newborns and is commonly treated with phototherapy. We describe the case of a neonate with hemolytic disease of the newborn who developed a rarely described purpuric eruption. Laboratory testing revealed elevated porphyrins.

The Role of Skin-to-Skin Contact and Breastfeeding in the First Hour Post Delivery in Reducing Excessive Weight Loss

BACKGROUND AND AIMS

An excessive weight loss (EWL) of >10% after birth is associated with serious health outcomes. The aim of this study was to determine factors that can reduce weight loss in full-term, exclusively breastfed infants after birth.

METHODS

This is a retrospective, observational, single-center study. We included 642 healthy, full-term, exclusively breastfed neonates born in 2019 in a baby-friendly hospital, and their healthy mothers. The exclusion criteria were as follows: supplementation with formula, multiple pregnancies, and neonates or mothers with health issues.

RESULTS

The mean percentage of neonatal weight loss after 24 h of life was 5.13%, and that after 48 h was 6.34%. Neonates delivered via a caesarean section lost more weight after 24 and 48 h of life than those delivered via vaginal delivery (p < 0.01). There is a noticeable pattern that neonates tend to lose more weight if they do not get skin-to-skin contact (SSC) and breastfeeding within the first hour after birth (p > 0.05).

CONCLUSIONS

Neonates born via a CS tend to lose more weight after 24 and 48 h of life. Immediate SSC and breastfeeding in the first hour after delivery may decrease the excessive weight loss.
