Increasing the Use of Newborn Pain Treatment Following the Implementation of a Parent-Targeted Video: An Outcome Evaluation

Background/Objectives: Despite strong evidence that breastfeeding, skin-to-skin care, and sucrose reduce pain in newborns during minor painful procedures, these interventions remain underutilized in practice. To address this knowledge-to-practice gap, we produced a five-minute parent-targeted video demonstrating the analgesic effects of these strategies and examined whether the use of newborn pain treatment increased in maternal–newborn care settings following the introduction of the video by nurses. Methods: The design was a pre–post outcome evaluation. The participants were infants born in eight maternal–newborn hospital units in Ontario, Canada. Data on newborn pain treatment were obtained from a provincial birth registry. Descriptive statistics and chi square tests were used to compare the before-and-after changes in the use of pain treatment. Results: Data on 15,524 infants were included. Overall, there was an increase in the proportion of newborns receiving any pain treatment comparing before (49%) and after (54%) the video intervention (p < 0.0001) and a decrease in the proportion of newborns receiving no pain treatment pre- (17.6%) and post-intervention (11.5%) (p < 0.0001). Most of the change aligned with increased sucrose use (35% to 47%, p < 0.0001) in three of the larger units. Nevertheless, considerable increases in the use of breastfeeding and/or skin-to-skin care (24% to 38%, p < 0.0001) were also observed in three of the smaller units. Conclusions: The video intervention was effective at increasing the use of pain treatment for newborns. Though the overall increases were modest, there were some large increases for specific methods of pain treatment in certain maternal–newborn units, reflecting the diversity in practice and context across different sites.

An Invisible Dermal Nanotattoo-Based Smart Wearable Sensor for eDiagnostics of Jaundice.

Despite substantial progress in the diagnosis of jaundice/hyperbilirubinemia as the most common disease and cause of hospitalization of newborns, on the eve of Industry/Healthcare 5.0, the development of accurate and reliable wearable diagnostic sensors for noninvasive smart monitoring of bilirubin (BIL) is still in high demand. Aiming to fabricate a smart wearable sensor for early diagnosis of neonatal jaundice and its therapeutic monitoring, we here report a fluorescent dermal nanotattoo that further coupled with an IoT-integrated wearable optoelectronic reader for minimally invasive, continuous, and real-time monitoring of BIL in interstitial fluid. Selective recovery of quenched fluorescence of the dermal tattoo sensor, composed of biocompatible dissolving/hydrogel microneedles loaded with fluorescent carbon quantum dots, upon blue light exposure used for jaundice phototherapy was utilized for highly selective BIL sensing. The fascinating features of our developed smart wearable tattoo sensor and its successful results with high correlation with blood BIL results make it a highly promising sensor for easy, minimally invasive, reliable, and smart eDiagnostics and continuous therapeutic eMonitoring of jaundice and other BIL-induced diseases at the point of care. We envision that the developed nanotattoo sensing bioplatform will inspire the development of future smart tattoo sensors in various diagnostic and monitoring scenarios.

Early onset neonatal sepsis and its associatited factors: a cross sectional study

BackgroundSepsis is the 3rd leading cause of neonatal mortality in Ethiopia contributing to 16% of neonatal death. In a hospital study, neonatal sepsis was the leading diagnosis at admission and the second leading cause of neonatal death at the neonatal intensive care unit. Among other factors repeated vaginal examination during labor is known to contribute to sepsis in low-income settings. However, there is limited evidence in the Ethiopian setting.ObjectiveThe objective of this study was to examine the association between early-onset neonatal sepsis and repeated vaginal examinations.MethodsThe study was conducted at Gandhi Memorial Hospital, a public maternity and newborn care hospital. We followed 672 mother-newborn pairs by phone until 7 days of age to detect clinical sepsis. Data were analyzed using SPSS version 20 software. Adjusted odds ratio risk (AOR) with a corresponding 95% confidence interval (CI) was used to show the strength of associations and variables with p-value < 0.05 were considered to be statistically significant.ResultsThe incidence of early-onset neonatal sepsis was found to be 20.83% (95% CI 17.60, 24.00). Having a frequent vaginal examination (four or more times) during labor and delivery, prolonged rupture of membranes, induced labor and gestational age < 37 weeks were strongly associated with the development of early-onset neonatal sepsis, (AOR 2. 69;95 CI: 1.08, 6.70) AOR 5.12(95% CI 1.31, 20.00), AOR of 5.24 (95% CI 1.72, AOR4.34 (95% CI 1.20, 15.68), 16.00), respectively.ConclusionFrequent digital vaginal examination prolonged rupture of membranes, induced labor and gestational age < 37 weeks significantly increases the risk of early onset neonatal sepsis. We also recommend further study using neonatal blood culture to better diagnose early onset neonatal sepsis objectively.

An Assessment of Neonatal Nurses' Knowledge and Provision of Child Passenger Safety Information.

Nurses who care for newborn infants in the hospital have an opportunity to serve as a resource for child passenger safety (CPS). Literature lacks information on what CPS knowledge and provision of information exists for neonatal nurses. In this study, we assessed neonatal nurses' knowledge and provision of CPS information. The study design included an adapted, cross-sectional, and anonymous survey. A generic survey link was distributed to National Association of Neonatal Nurses' members. Descriptive and univariate analyses were used to summarize the data. One hundred thirteen registered nurses working in the hospital, representing 27 states, completed the survey. Approximately 38.1% (N = 43) "high knowledge" respondents answered 2 scenario-based and 3 knowledge-based CPS questions correctly. Nurses addressed CPS for parents/caregivers during newborn hospitalization through car seat tolerance screenings (85.8%), verbal education or answering questions (83.2%), and providing a pamphlet or handout (52.2%). Barriers to providing CPS recommendations were nursing staff not being trained in CPS (55.8%), perceived liability (50.4%), and lack of understanding/unaware of CPS guidelines (47.8%). Neonatal nurses can benefit from CPS training and hospital policies which outline nurse expectations and liabilities.

Paid Family Leave and Prevention of Acute Respiratory Infections in Young Infants

Acute respiratory tract infections are the leading cause of emergency department visits and hospitalizations in US children, with highest risks in the first 2 months after birth. Out-of-home childcare settings increase the spread of respiratory tract infections. The study team hypothesized that access to state-paid family leave could reduce acute care encounters (hospital admissions or emergency department visits) for respiratory tract infections in young infants by reducing out-of-home childcare transmissions. To determine if the 2018 introduction of paid family leave in New York state reduced acute care encounters for respiratory tract infections in infants 8 weeks or younger. This population-based study of acute care encounters took place in New York state and New England control states (Maine, Massachusetts, New Hampshire, Vermont) from October 2015 through February 2020. Participants included infants aged 8 weeks or younger. Controlled time series analysis using Poisson regression was used to estimate the impact of paid family leave on acute care encounters for respiratory tract infections, comparing observed counts during respiratory virus season (October through March) with those predicted in the absence of the policy. Acute care encounters for respiratory tract infections in 1-year-olds (who would not be expected to benefit as directly from the policy) were modeled as a placebo test. New York State Paid Family Leave policy, introduced on January 1, 2018, providing 8 weeks of paid leave for eligible parents. Emergency department visits or hospitalizations with International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD) codes for upper or lower respiratory tract infections or associated symptoms (ie, fever, cough), excluding newborn hospitalizations. The secondary outcome was acute care encounters for respiratory syncytial virus (RSV) bronchiolitis. There were 52 943 acute care encounters for respiratory infection among infants 8 weeks or younger. There were 15 932 encounters that were hospitalizations (30%) and 33 304 of the encounters were paid for by Medicaid (63%). Encounters were 18% lower than predicted (relative percentage change = -17.9; 95% CI, -20.3 to -15.7) after the introduction of paid family leave. RSV encounters were 27.0% lower (95% CI, -30.9 to -23.5) than predicted. Similar reductions were not observed in 1-year-olds (relative percentage change = -1.5; 95% CI, -2.5 to -0.6). New York state's paid family leave policy was associated with reduced acute care encounters for respiratory tract infections in young infants. These findings may be useful for informing implementation of paid family leave federally and in the states that have not enacted paid family leave policies.

Evaluation of a Risk Screening Checklist for Venous Thromboembolism Prophylaxis in a Women and Newborn Hospital.

The venous thromboembolism (VTE) risk screening forms were developed to allow for recording identified risk factors for VTE including thrombophilia, history of VTE, postpartum hemorrhage, and cesarean delivery, and documentation of specific actions taken to mitigate these risks and reduce complications due to VTE. Compliance with hospital guidelines in assessing VTE risk and appropriate prescribing of thromboprophylaxis was evaluated prior to the introduction of VTE risk screening forms (March 2022). Efficacy of the new VTE risk screening forms was also assessed (April 2023). Patient discharge summaries and patient medical records including medication charts were used to review the documentation of VTE risk assessments and details of thromboprophylaxis prescribing. Of 74 postnatal patients, 37.8% had VTE risk assessment documented prior to the introduction of VTE risk screening forms. Of 37 patients identified to be at moderate to high risk of VTE requiring pharmacological prophylaxis, 70.3% (n = 26) were appropriately prescribed pharmacological prophylaxis. After the risk screening forms were introduced, a total of 67 antenatal, postnatal, and gynecologic patients were studied. Of these, 32.8% (n = 22) of patients had all required fields completed appropriately. When using the forms, 26.9% (n = 7) of postnatal and 88% (n = 22) of gynecological patients were rated as medium or high risk, and all received medical review within 24 hours. Pharmacological prophylaxis was indicated in 88% (n = 22) of gynecological, 43.8% (n = 7) of antenatal, and 38.5% (n = 10) of postnatal patients, and all were appropriately prescribed. The guideline review and introduction of VTE risk screening forms was valuable to provide guidance in the risk assessment for VTE and to identify patients requiring prophylaxis.

Pre- and Periviable PPROM after Fetoscopic Laser Surgery: Are Survival Outcomes Better than We Think?

Limited data exist regarding outcomes when pre- and periviable PPROM (PPROM ≤26 weeks of gestation) occurs as a complication of fetoscopic laser surgery (FLS) for twin-twin transfusion syndrome (TTTS). This is a retrospective cohort study of FLS cases performed at a single institution between January 2015 and May 2021. Study inclusion was limited to patients with monochorionic-diamniotic twin pregnancies complicated by TTTS who underwent FLS. Patients were grouped by pPPROM status, and further stratified to those continuing with expectant management, and outcomes were compared between groups. The primary outcome was survival to live birth of at least one twin. During the study period, 171 patients underwent FLS and a total of 96 (56.1%) subjects satisfied inclusion criteria. Among included subjects, 18 (18.8%) experienced pPPROM after FLS and 78 (81.2%) did not. Baseline characteristics were similar between groups. Among patients with pPPROM, 11 (61.1%) pursued expectant management and 7 (38.9%) opted for pregnancy termination. Among expectantly managed subjects, median pPPROM-to-delivery interval was 47.0 days (6.0-66.0 IQR) with a median gestational age at delivery of 29+1 weeks (24 + 4-33 + 6 IQR). Rates of survival to live birth of at least one twin (90.9% vs. 96.2% p = 0.42) were similar between those with pPPROM undergoing expectant management and those without pPPROM. Dual survivorship (45.5% vs. 78.2%, p = 0.03), perinatal survival to live birth (68.2% vs. 87.2%, p = 0.05), and perinatal survival to newborn hospital discharge (59.1% vs. 85.9%, p = &lt;0.01) were all significantly lower among those with pPPROM. Gestational age at delivery was lower among those continuing with pregnancies complicated by pPPROM (29 + 1 vs. 32+5 weeks, p = &lt;0.01). Survival of at least one twin to live birth remained high among those pursing expectant management after experiencing post-FLS pPPROM, suggesting that the outlook after this complication is not necessarily poor. However, this complication was associated with lower chances of dual survival and greater prematurity.

Newborn readmissions and virtual primary care delivery: a population-based case-control study

BackgroundEarly post-discharge assessments for newborns are recommended. Virtual care has become more prevalent during the pandemic, providing an opportunity to better understand its impact on the quality of post-discharge newborn care. The objective of this study was to understand whether primary care visit modality (in-person vs. virtual) is associated with early newborn hospital readmissions and emergency department (ED) visits.MethodsWe conducted a population-based, case-control study using linked health administrative databases between September 1, 2020 and March 31, 2022 in Ontario, Canada. We compared the modality of primary care visits among cases (hospital readmission within 14 days of life) and controls (newborns without a readmission), matched on infant sex, gestational age, and maternal parity. We included an alternative definition of cases as a composite of either a newborn hospital readmission or emergency department (ED) visit or in-hospital death within the first 14 days of life. Conditional logistic regression models were used to model odds ratios (ORs), comparing those exposed to a virtual visit versus in-person visit, adjusting for infant birth weight, birth hospitalization length of stay, neighbourhood level material deprivation, rurality and presence of active maternal comorbidities.ResultsAmong 73,324 eligible newborns, 2,220 experienced a hospital readmission within 14 days of life and were matched to 8,880 controls. Jaundice was the primary reason for readmission (75% of readmissions). Compared to newborns who were seen in-person post-discharge, newborns who were seen virtually had higher odds of hospital readmission (adjusted odds ratio [aOR] 1.41 (95% CI 1.09, 1.83); the magnitude of effect was not different using the composite outcome (aOR 1.35, 95% CI 1.05, 1.75).ConclusionsNewborns who receive a virtual post-discharge visit are more likely than those who receive an in-person visit to require hospital readmission.

Follow-Up of Secundum ASD, Muscular VSD, or PDA Diagnosed During Neonatal Hospitalization.

The ideal follow-up of neonates who have a secundum atrial septal defect (ASD), muscular ventricular septal defect (VSD), or patent ductus arteriosus (PDA) remains uncertain. Newborns with findings limited to a secundum ASD, muscular VSD, and/or PDA on their neonatal hospitalization discharge echocardiogram and at least one outpatient follow-up echocardiogram performed between 9-1-17 and 9-1-21 were evaluated and patient follow-up assessed through 9-1-23. 95 infants met inclusion criteria. 43 infants had a secundum ASD, 41 had a muscular VSD, and 54 had a PDA at newborn hospital discharge. 39/95 had more than one intracardiac shunt. 56 were discharged from care, 26 were still in follow-up and 13 were lost to recommended follow-up. No patients received intervention during the follow-up period of 2 to 6years. Of the 43 infants with a secundum ASD, 16 (37.2%) had demonstrated closure of the ASD, and 13 (30.2%) were discharged from care with an ASD < 3.5mm in diameter. 3/43 infants with secundum ASD had a defect with a diameter of more than 5mm at their last echocardiogram. No infant discharged from their neonatal hospitalization with a secundum ASD, muscular VSD, or PDA needed any intervention from 2 to 6years of follow-up. Ongoing follow-up with echocardiography of those infants with a secundum ASD is of greater value than of those with muscular VSD or PDA.

Knowledge of Neonatal Danger Signs among Postnatal Mothers at Women and New born Hospital - University Teaching Hospitals in Lusaka Zambia.

Purpose: The awareness and identification of neonatal danger signs by mothers play a significant role in a neonate's survival and future health. The survival of neonates is thought to be increased by providing a clear understanding of neonatal danger signs. This study aimed to assess postnatal mothers' knowledge of neonatal danger signs and associated factors. Methodology: A cross-sectional analytical study design was used to conduct a study at Women and Newborn Hospital UTH in Lusaka Zambia with a total number of 150 participants. Participants recruited in the study included all mothers aged 18 and above seeking care at UTH from day six today twenty-eight after delivery. Data was collected using the validated Neonatal Danger Signs Knowledge and Practices Questionnaire (NDSKQ) tool and SPSS version 26 was used to analyse data. A Binary logistic regression analysis was done to identify factors associated with Neonatal danger signs. Findings: Slightly above half (53%) of the respondents had poor knowledge on neonatal danger signs. Age, marital status, educational level, parity, antenatal care attendance and family support system were associated with knowledge on neonatal danger signs with all p values of less than or equal to 0.05. Younger mothers (18-20 years) (56.5%) were more likely to have poor knowledge compared to older mothers. Married mothers (68%) and those who were divorced or widowed (60%) were more likely to have better knowledge compared to single mothers, mothers with tertiary education (60%) had better knowledge compared to those with none/primary education (58%), mothers with more children (66.7%) were less likely to have poor knowledge compared to those with their first child (50%), mothers who attended antenatal care six times or more (67.1%) had better knowledge compared to those who attended five times or less (53.8%) and mothers with a family support system (75%) were more likely to have good knowledge compared to those without (53%) all the associations were statistically significant. Unique contribution to theory, policy and practice: There is need to focus on training in maternal identification of neonatal danger signs. Personalised education for mothers, considering age and education level, and integrating family involvement and cultural competence into care delivery are crucial. Nursing education should advance through specialized curricula, utilizing advanced simulation training and interdisciplinary collaboration to enhance clinical skills in identification of neonatal danger signs and promote maternal awareness of neonatal dangers signs, ultimately improving neonatal health.

Seizures in Asphyxiated Term Newborns Based on Admission Thompson Score at the Women and Newborn Hospital, University Teaching Hospitals in Lusaka, Zambia.

Purpose: The main purpose of the study was to investigate seizures in asphyxiated term neonates based on the admission Thompson score at the University of Zambia, Women and New-born Neonatal Intensive Care Unit. Methodology: A cross-sectional descriptive study design was used to conduct the study between (May 2022 to April 2023) in the Neonatal Intensive Care Unit (NICU) at the University Teaching Hospital for Women and Newborns in Lusaka Zambia. Stratified sampling was used to collect 217 files of neonates born at the tertiary facility as well as those referred from other centres with Apgar scores of ≤ 7 at one and five minutes of life. A structured questionnaire was used to collect data from medical records, the Thompson score (TS) was assessed on admission and details of neonatal seizures were analyzed using chi-square, fisher’s exact test and multivariable logistic regression. Findings: On admission, TS assessment was conducted on all 217 neonates of which 169 (77.9 %) neonates were classified with mild HIE,45 (20.9 %) moderate and 3(1.4 %) with severe HIE. Most neonates (77.4%) presented with seizures on admission. Results of the chi-square and fisher's exact tests showed that Thompson's score on admission was significantly associated with seizure occurrence (p=0.001). On multivariable binary logistic regression neonates with moderate HIE had over 10 times more odds of seizure occurrence compared to neonates with a mild HIE score (aOR=10.6, CI=2.32, 48.1, p=0.002). A unique contribution to theory, practice, and policy: The study concluded that seizures were present in all categories of HIE, the majority of who were classified with moderate HIE based on the Thompson score. Therefore, improving the quality of intrapartum care at the Women and Newborn Hospital can significantly reduce the occurrence of asphyxia and its complication.

Congenital Syphilis in Live Births: Adverse Outcomes, Hospital Length of Stay, and Costs.

To examine temporal trends and risk factors for congenital syphilis in newborn hospitalizations and to evaluate the association between adverse outcomes and congenital syphilis and health care utilization for newborn hospitalizations complicated by congenital syphilis. We conducted a retrospective, cross-sectional study using data from the National Inpatient Sample to identify newborn hospitalizations in the United States between 2016 and 2020. Newborns with congenital syphilis were identified with International Classification of Diseases, Tenth Revision, Clinical Modification codes. Adverse outcomes, hospital length of stay, and hospital costs were examined. The annual percent change was calculated to assess congenital syphilis trend. A multivariable Poisson regression model with robust error variance was used to examine the association between congenital syphilis and adverse outcomes. Adjusted relative risks (RRs) with 95% CIs were calculated. A multivariable generalized linear regression model was used to examine the association between congenital syphilis and hospital length of stay and hospital costs. Adjusted mean ratios with 95% CIs were calculated. Of 18,119,871 newborn hospitalizations in the United States between 2016 and 2020, the rate of congenital syphilis increased over time (annual percent change 24.6%, 95% CI, 13.0-37.3). Newborn race and ethnicity, insurance, household income, year of admission, and hospital characteristics were associated with congenital syphilis. In multivariable models, congenital syphilis was associated with preterm birth before 37 weeks of gestation (adjusted RR 2.22, 95% CI, 2.02-2.44) and preterm birth before 34 weeks of gestation (adjusted RR 2.39, 95% CI, 2.01-2.84); however, there was no association with low birth weight or neonatal in-hospital death. Compared with newborns without congenital syphilis, hospital length of stay (adjusted mean ratio 3.53, 95% CI, 3.38-3.68) and hospital costs (adjusted mean ratio 4.93, 95% CI, 4.57-5.32) were higher among those with congenital syphilis. Among newborn hospitalizations in the United States, the rate of congenital syphilis increased from 2016 to 2020. Congenital syphilis was associated with preterm birth, longer hospital length of stay, and higher hospital costs.

Neonatal transfer and duration of hospitalization of newborns as potential risk factors for impaired mother-infant bonding: The Japan Environment and Children's Study

BackgroundCurrently, there is no consensus regarding the relationship between neonatal transfer and duration of hospitalization in cases of impaired mother-infant bonding (MIB). This study aimed to determine whether neonatal transfer and duration of hospitalization of newborns increase the risk for impaired MIB. MethodsThe MIB Scale was used to assess impaired MIB 1 year after delivery, using data from the Japan Environment and Children's Study. A score ≥ 5 points indicated impaired MIB. Multiple logistic regression analyses were performed to estimate the association between neonatal transfer and duration of hospitalization of newborns with the risk of impaired MIB. ResultsA total of 66,402 pregnant women were included in the study. The overall incidence rate of impaired MIB was 11.2 %. The mean duration of hospitalization of newborns was 7.1 ± 6.4 days. After adjusting for potential confounders, neonatal transfer (adjusted odd ratio (OR): 1.13 [95 % confidence interval (CI)), 1.01–1.27]) and duration of hospitalization of newborns (adjusted OR 1.007; 95 % CI 1.003–1.010) were associated with impaired MIB. The area under the receiver operating characteristic curve for the duration of hospitalization of newborns for impaired MIB was 0.53. LimitationsMaternal childhood abuse and neglect history were not evaluated, and information regarding whether the infants were admitted to the neonatal intensive care unit was unavailable. ConclusionsJapanese women whose newborns underwent neonatal transfer should be followed up for at least 1 year after delivery, regardless of the duration of hospitalization of newborns.

Awareness and Knowledge Level of Puerperal Mothers on Neonatal Jaundice: A Qualitative Study in Northern Ghana

Background: Neonatal Jaundice is a major contributing cause of newborn hospitalizations and a major cause of newborn mortality. It should not be a major cause of mortality even in developing countries Inadequate knowledge of mothers about NNJ results in delayed decision-making to seek timely medical interventions. Methods: Using an exploratory design, a semi-structured interview guide was used to assess puerperal mothers' knowledge of NNJ. A purposive sampling technique was used to select 15 mothers Too small size attend health services at the Tamale West Hospital with newborns sick of NNJ. An interview guide through an in-depth interview process was used to gather data. Interviews were recorded and transcribed before analyzing thematically to organize the data into major and sub-themes. Results: Awareness of NNJ was above average, the majority of mothers had knowledge of NNJ. Reported signs and symptoms of NNJ include yellowish eyes, palms, and skin. Treatment of jaundice was cited to include the use of phototherapy, and frequent breastfeeding. Causes and risk factors associated were; infections, G6PD defects, and consumption of herbal concoctions. Conclusions: Health education should be intensified at the various units of the hospital to correct cultural and religious practices and improve caregivers' and mothers understanding of NNJ.

Proposed Screening for Congenital Hyperinsulinism in Newborns: Perspective from a Neonatal-Perinatal Medicine Group.

This perspective work by academic neonatal providers is written specifically for the audience of newborn care providers and neonatologists involved in neonatal hypoglycemia screening. Herein, we propose adding a screen for congenital hyperinsulinism (CHI) by measuring glucose and ketone (i.e., β-hydroxybutyrate (BOHB)) concentrations just prior to newborn hospital discharge and as close to 48 h after birth as possible, at the same time that the mandated state Newborn Dried Blood Spot Screen is obtained. In the proposed protocol, we do not recommend specific metabolite cutoffs, as our primary objective is to simply highlight the concept of screening for CHI in newborns to newborn caregivers. The premise for our proposed screen is based on the known effect of hyperinsulinism in suppressing ketogenesis, thereby limiting ketone production. We will briefly discuss genetic CHI, other forms of neonatal hypoglycemia, and their shared mechanisms; the mechanism of insulin regulation by functional pancreatic islet cell membrane KATP channels; adverse neurodevelopmental sequelae and brain injury due to missing or delaying the CHI diagnosis; the principles of a good screening test; how current neonatal hypoglycemia screening programs do not fulfill the criteria for being effective screening tests; and our proposed algorithm for screening for CHI in newborns.

Infective Endocarditis due to Unusual Pathogens Complicated with Pulmonary Thromboembolism: A Rare Occurrence in a Premature Infant

Background: Survival of low birth weight preterm neonates has increased with the availability of better neonatal care, however, the use of central lines for longer duration increases the risk of bacterial and fungal sepsis. Neonatal infective endocarditis (IE) is a rare presentation of neonatal sepsis and is often associated with complications and high mortality. Clinical Description: A 36 weeker, premature baby, hospitalized for early onset sepsis, was transferred to our hospital on day 15 of life, with an umbilical catheter in situ, with fever, respiratory distress, and persistent thrombocytopenia. Clinical examination revealed decreased oxygen saturation, crepitations in the right lung field, systolic murmur, and hepatomegaly. Management and Outcome: Baseline investigations revealed positive septic screen with thrombocytopenia with meningitis, neonatal cholestasis, and right sided consolidation on chest X ray. A two dimensional echocardiography (ECHO) revealed vegetation on the tricuspid valve, and blood culture from two sites revealed growth of Candida tropicalis and Serratia marcescens. Colistin, tigecycline, and amphotericin B therapy were initiated as per sensitivity along with low molecular weight heparin for prevention of embolization. The baby developed acute worsening in respiratory distress after 4 weeks of therapy. Repeat ECHO revealed increased size of cardiac vegetation and computed tomography of thorax with pulmonary angiography revealed pulmonary thromboembolism. Unfortunately, the baby succumbed to complications of IE. Conclusion: Invasive instrumentations such as umbilical catheterization and prolonged hospitalizations of premature newborns predispose them to develop IE, especially with unusual organisms. Such infections have a complicated course and may be fatal.

Assessment of risk factors for Neonatal Abstinence Syndrome (NAS) using a Standardized Surveillance Case Definition in Clark County, NV

Background: Neonatal Abstinence Syndrome (NAS) is a withdrawal syndrome in neonates that can occur due to drug exposure during pregnancy. This study had two objectives: (1) Assess the implementation of the Council of State and Territorial Epidemiologists (CSTE) Tier 2 case definition for NAS surveillance in Clark County, Nevada and (2) Identify risk factors for NAS. Subjects and Method: This study utilized hospital discharge data. Claim-based records from non-federal acute care hospitals located in Clark County during 2016-2022 were analyzed. All newborn inpatient discharge records from January 1, 2016 to September 30, 2022 in Clark County, Nevada were selected. ICD-10-CM codes were utilized based on the CSTE Tier 2 case definition. Any neonate record that met the case definition, including any record with the diagnosis code P96.1, was considered a NAS confirmed case. Codes for suspect cases, maternal history of substance use, unspecified maternal medication, and transmitted noxious-substances were also assessed. A multiple logistic regression model using backward stepwise selection was developed to find risk factors related to NAS-confirmed births. Results: In Clark County, Nevada, the NAS incidence rate from January 2016 to September 2022 was 7.4 per 1,000 births. In 2022 alone, the rate of NAS was 8.9 per 1,000 births. Estimated rates of NAS were highest among neonates who were White at 13 per 1,000 births. Hospital J, the largest academic medical center in Southern Nevada, had the highest NAS confirmed case rate at 11.3 per 1000 newborn hospitalizations. Results from the multiple logistic regression model showed the odds of being born with NAS among neonates who identified as White were 5.0 (OR=5.17; 95% CI= 4.29 to 6.24; p &lt;0.001) times more likely to have NAS compared to the Hispanic group. Conclusion: Given that 2022 had the highest rate of confirmed NAS cases there is a need to collect substance and diagnosis-specific data about prenatal substance use to identify unmet service care and disparities.

Prenatal Predictors for Pulmonary Balloon Valvuloplasty in the Newborn.

Pulmonary balloon valvuloplasty (PBV) is the treatment of choice for subjects with isolated pulmonary valve stenosis (IPS). The purpose of this study was to define fetal echocardiographic features associated with an inpatient PBV prior to newborn hospital discharge and characterize resource utilization of IPS fetuses among participating centers. Six center, retrospective case series of singleton fetuses identified between 2010 and 2020 with IPS. Third-trimester echocardiogram data was compared with postnatal data, included pulmonary valve Doppler velocities, pulmonary valve insufficiency and ductus arteriosus flow direction. Comparison between subjects who underwent inpatient PBV during their newborn hospital admission versus those infants referred for outpatient PBV after initial hospital discharge. We analyzed data by logistic regression, student t test and Chi-Square testing with a p value of ≤ 0.05 considered statistically significant. Forty-nine IPS fetuses were identified. Thirty-eight (78%) underwent inpatient PBV at 5 (range 1-58) days and 11 (22%) underwent outpatient PBV at 51.8 (11-174) days. Newborns requiring an inpatient PBV were more likely to have one or more characteristics on 3rd-trimester fetal echocardiogram: left to right or bidirectional ductus arteriosus flow (61% vs 0%), and/or a peak pulmonary valve velocity > 3.0m/s (odds ratio 16.9, 95% confidence interval 3.02-94.17) with a sensitivity of 90.4% and specificity of 97.7%. Ductus arteriosus flow direction and pulmonary valve peak velocity in the 3rd trimester can successfully predict the need for newborn inpatient PBV. We speculate these findings may be useful in choosing delivery site for the pregnancy complicated by fetal IPS.

Evaluation of the Stability of Newborn Hospital Parenteral Nutrition Solutions.

(1) Background: parenteral nutrition (PN) solutions are an extremely complex mixture. It is composed of a multitude of chemical elements that can give rise to a large number of interactions that condition its stability and safety. The aim of this study was to evaluate the stability of PN solutions for preterm infants. (2) Methods: eight samples were prepared according to the protocol for prescribing PN in preterm infants. Samples PN1-PN7 had the normal progression of macronutrients and standard amounts of micronutrients for a 1 kg preterm infant. The PN8 sample had a high concentration of electrolytes, with the idea of forcing stability limits. Samples were stored both at room temperature and under refrigeration. Measurements of globule size, pH, density, and viscosity were performed in both storage protocols on different days after processing. (3) Results: the changes in the composition of the samples did not affect the evolution of the stability at the different measurement times and temperatures. Viscosity was affected by the compositional changes made in the PN samples, but no alterations due to time or temperature were observed. Density and pH remained stable, without significant changes due to time, storage temperature, or different composition. (4) Conclusion: all samples remained stable during the study period and did not undergo significant alterations due to compositional changes or different experimental conditions.

Newborn Hospitalizations Before and During COVID-19 Pandemic in Poland: A Comparative Study Based on a National Hospital Registry.

Objectives: There are limited data on the impact of the COVID-19 outbreak in Poland on newborn health. The aim of the study is to show recent information on hospitalizations of newborns in Poland in the pre-pandemic and COVID-19 pandemic era. Methods: A retrospective, population-based study was conducted using data from hospital discharge records of patients hospitalized in 2017-2021. Results: The data on which the study was based consisted of a substantial number of 104,450 hospitalization records. Annual hospitalization rate was estimated to be 50.3-51.9 per 1,000 in 2017-2019, 56 per 1,000 in 2020 and it rose to 77.7 per 1,000 in 2021. In comparison to the pre-pandemic period, in the COVID-19 era, we observed significantly more hospitalization cases of newborns affected by maternal renal and urinary tract diseases (p < 0.001), syndrome of infant of mother with gestational diabetes (p < 0.001), maternal complications of pregnancy (p < 0.001). In the COVID-19 era, the prevalence of COVID-19 among newborns was 4.5 cases per 1,000 newborn hospitalizations. Conclusion: The COVID-19 pandemic outbreak could significantly contribute to qualitative and quantitative changes in hospitalizations among newborns.
