Objective Hypoglycemia, the most common metabolic derangement in the newborn period remains a contentious issue, not only due to various numerical definitions, but also due to limited therapeutical options which either lack evidence to support their efficacy or are increasingly recognized to lead to adverse reactions in this population. This study aimed to investigate neonatologists' current attitudes in diagnosing and managing transient and persistent hypoglycemia in newborns admitted to the Neonatal Intensive Care Unit (NICU). Methods A web-based electronic survey which included 34 questions and a clinical vignette was sent to U.S. neonatologists. Results There were 246 survey responses with most respondents using local protocols to manage this condition. The median glucose value used as the numerical definition of hypoglycemia in first 48 hours of life (HOL) for symptomatic and asymptomatic term infants and preterm infants was 45 mg/dL (2.5 mmol/L; 25–60 mg/dL; 1.4–3.3 mmol/L), while after 48 HOL the median value was 50 mg/dL (2.8 mmol/L; 30–70 mg/dL; 1.7–3.9 mmol/L). There were various approaches used to manage transient and persistent hypoglycemia that included dextrose gel, increasing caloric content of the feeds using milk fortifiers, using continuous feedings, formula or complex carbohydrates, and use of various medications such as diazoxide, glucocorticoids, and glucagon. Conclusion There is still large variability in current practices related to hypoglycemia. Further research is needed not only to provide evidence to support the values used as a numerical definition for hypoglycemia, but also on the efficacy of current strategies used to manage this condition. Key Points Numerical definition of glucose remains variable. Strategies managing transient and persistent hypoglycemia are diverse. There is a need for further research to investigate efficacy of various treatment options. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to identify risk factors for perioperative complications and long‐term morbidity in infants from the neonatal intensive care unit (NICU) presenting for a tracheostomy. Methods: This single‐center retrospective cohort study included infants in the NICU presenting for a tracheostomy from August 2011 to December 2019. Primary outcomes were categorized as either a perioperative complication or long‐term morbidity. A severe perioperative complication was defined as having either (1) an intraoperative cardiopulmonary arrest, (2) an intraoperative death, (3) a postoperative cardiopulmonary arrest within 30 days of the procedure, or (4) a postoperative death within 30 days of the procedure. Long‐term morbidities included (1) the need for gastrostomy tube placement within the tracheostomy hospitalization and (2) the need for diuretic therapy, pulmonary hypertensive therapy, oxygen, or mechanical ventilation at 12 and 24 months following the tracheostomy. Results: One‐hundred eighty‐three children underwent a tracheostomy. The mean age at tracheostomy was 16.9 weeks while the mean post‐conceptual age at tracheostomy was 49.7 weeks. The incidence of severe perioperative complications was 4.4% (n = 8) with the number of pulmonary hypertension medication classes preoperatively (OR: 3.64, 95% CI: (1.44–8.94), p = 0.005) as a significant risk factor. Approximately 81% of children additionally had a gastrostomy tube placed at the time of the tracheostomy, and 62% were ventilator‐dependent 2 years following their tracheostomy. Conclusion: Our study provides critical perioperative complications and long‐term morbidity data to neonatologists, pediatricians, surgeons, anesthesiologists, and families in the expected course of infants from the NICU presenting for a tracheostomy.

Background: To determine variables associated with outcomes in infants with intestinal failure (IF) and ostomy following reanastomosis (RA). Methods: A single‐center, descriptive cohort study of 120 infants with IF and a stoma from January 2011 to December 2020 with subsequent RA during initial hospitalization. The primary outcome was achievement of enteral autonomy (EA) following RA. Other outcomes were duration of hospital stay, and mortality. Penalized logistic regression and linear regression were used for data analysis. Results: The median gestational age was 26 weeks, and the median birth weight was 890 g. Three infants died. The median duration between ostomy creation and RA was 80 days (interquartile range; 62.5, 100.5). For each additional day of discontinuity, the odds of EA decreased by 2% (odds ratio [OR] = 0.980; 95% confidence interval [CI]: 0.962, 0.999; P = 0.038), and death increased by 4.2% (OR = 1.042; 95% CI: 1.010, 1.075; P = 0.009). For each additional mL/kg/day of enteral feeds at RA, the odds of EA increased by 7.5% (OR = 1.075; 95% CI: 1.027, 1.126, P = 0.002) and duration of hospital stay decreased by 0.35 days (slope coefficient = −0.351; 95% CI: −0.540, −0.163; P < 0.001). Conclusion: Shorter duration of intestinal discontinuity and enteral nutrition before RA could positively influence EA and duration of stay in infants with IF and ostomy following RA.

Aim: To investigate the self‐reported levels of social support from friends and family and from nurses as mediators of the relationship between self‐rated physical and psychological condition in hospitalised patients. Design: Cross‐sectional study of adult inpatients at a large tertiary‐care hospital in the northeast United States. Methods: Multiple mediation analysis of survey data. Results: In surveys received from 324 inpatients, one fourth of the variation in patients' self‐rated psychological condition was explained by self‐rated physical condition. Social support from family and friends mediated a significant proportion (11.0%) of the relationship between self‐rated physical and psychological condition, however social support from nurses did not. Conclusion: Social support from family and friends can positively influence the psychological health of inpatients, but nurses are not an adequate replacement for the social support provided by family and friends. Implications for Nursing: Although nurses cannot replace the social support provided by family and friends, the assessment of social isolation and care planning of interventions to support patients is a fundamental nursing role. Technology to connect patients with friends and family should be used to mitigate isolation for hospitalised patients unable to receive in‐person visits from loved ones. Impact: The influence of social support from family and friends and nurses was addressed. The study found social support from family and friends, but not nurses, to influence the relationship between physical and psychological ratings. This finding has implications for the role of nurses in the hospital setting. Reporting Method: Strengthening the Reporting of Observational Studies in Epidemiology guidelines were followed.

Background and Objectives: Blood transfusion is frequently needed to maintain adequate haemostasis and improve oxygenation for patients treated with extracorporeal membrane oxygenation (ECMO). It is more so for neonates with immature coagulation systems who require surgical intervention such as congenital diaphragmatic hernia (CDH) repair. There is growing evidence suggesting an association between blood transfusions and increased mortality. The aim of this study is to evaluate the association of blood transfusions during the peri‐operative period of CDH repair, among other clinical parameters, with mortality in neonates undergoing on‐ECMO CDH repair. Materials and Methods: We performed a single centre retrospective chart review of all neonates with CDH undergoing on‐ECMO surgical repair from January 2010 to December 2020. Logistic regression was used to investigate associations with survival status. Results: Sixty‐two patients met the inclusion criteria. Platelet transfusions (odds ratio [OR] 1.42, 95% confidence interval [CI]: 1.06–1.90) in the post‐operative period and ECMO duration (OR 1.17, 95% CI: 1.05–1.30) were associated with increased mortality. Major bleeding complications had the strongest association with mortality (OR 10.98, 95% CI: 3.27–36.91). Gestational age, birth weight, Apgar scores, sex, blood type, right versus left CDH, venovenous versus venoarterial ECMO and duration of ECMO before CDH repair and circuit change after adjusting for ECMO duration were not significantly associated with survival. Conclusion: Platelet transfusion in the post‐operative period and major bleeding are associated with increased mortality in CDH neonates with surgical repair. The data suggest a need to develop robust plans for monitoring and preventing coagulation aberrancies during neonatal ECMO support. [ABSTRACT FROM AUTHOR]

Nurse practitioners (NPs) and physician assistants (PAs) have an important role in delivery of care in a tertiary children's hospital emergency department (ED). Most NPs and PAs have not had any formal training to work in a pediatric ED; although our NPs and PAs had no formal ED training, some were acute care certified. We describe a curriculum designed to improve knowledge and skills of NPs and PAs in the pediatric ED. The curriculum consists of three modules, namely, online lecture series, procedural workshops, and case scenarios in a simulated setting. Module 1 consisted of online lecture on 10 common ED diagnoses. The second module consisted of procedural workshops on lumbar puncture, incision and drainage of abscesses, gastrostomy insertion, and laceration repair. The third module included simulation scenarios on ED-specific cases of seizure in an infant, bronchiolitis and ruptured appendicitis with shock. Each module was evaluated by a survey. Participants rated each item on the survey using a Likert scale response (1 = disagree completely to 5 = agree completely). Both NPs and PAs demonstrated increase in knowledge scores in posttest 1 vs pretest (p < .001) and did not show a significant decline in posttest 2 (p = .073). The mean ratings of components of the online lecture series, workshops, and simulation scenarios were 4.5-4.7, 4.4-4.8, and 4.5-4.7, respectively, with positive comments. This novel curriculum meets the educational needs of NPs and PAs at our institution and can be used as a model to train them at other tertiary care pediatric EDs. [ABSTRACT FROM AUTHOR]

Objective  Survival of preterm infants differs dramatically depending on birthplace. No previous studies have compared outcomes of preterm infants between low middle-income and high-income countries such as India and the United States. The purpose of this study is to evaluate differences in care practices, resources, mortality, and morbidities in preterm infants with birth weight 700 to 1,500 g between two major neonatal centers in these countries. Study Design  This is a retrospective cohort study with de-identified data from Fernandez Hospital (FH) in Hyderabad, India, and Texas Children's Hospital (TCH) in Houston, TX, for infants born January 2016 to December 2018, and weighing 700 to 1,500 g at birth. The primary outcome was death before hospital discharge. Results  Of 1,195 infants, 736 were admitted to FH and 459 were admitted to TCH. After controlling for differences in gestational age, small for gestational age, and antenatal corticosteroid use, TCH patients had lower mortality before hospital discharge (adjusted odds ratio [aOR] = 0.28, 95% confidence interval [CI]: 0.16–0.48, p  < 0.001) and more bronchopulmonary dysplasia (BPD; aOR = 2.2, 95% CI: 1.51–3.21, p  < 0.001). The composite outcome of death or BPD and death or any major morbidity (BPD or intraventricular hemorrhage grade II or more or periventricular leukomalacia grade II or more or retinopathy of prematurity requiring treatment) were not different. Conclusion  In this study, TCH infants had decreased odds of death before hospital discharge compared with FH but higher odds of BPD, which may be related to increased survival and differences in care practices. Key Points Few studies compared outcomes of premature infants between different high-income countries. There are no studies comparing preterm infants between low middle-income and high-income countries such as India and the United States. This study evaluated detailed comparison of care practices and infrastructure of NICUs in India and United states. [ABSTRACT FROM AUTHOR]

Abstract Objective To study the retropharyngeal lymph node status (RPLN) by pretreatment PET-CT imaging in patients with squamous cell carcinomas of the oropharynx (OPSCC). Study Design: Retrospective. Methods 101 patients with a biopsy proven OPSCC were identified. 53 patients meeting inclusion criteria were further analyzed. Results The frequency of RPLN was 20.8% (11/53). Advanced T stage cancer (OR = 5.6250, 95% CI: 1.06 - 29.80, p = 0.0410) and advanced clinical N stage cancer (i.e. N2+) had higher odds (OR = 3.9773, 95% CI: 0.9628 - 16.4291) of being RPLN positive as compared to N0-1 patients. Conclusions Pre-treatment PET-CT can be used as a staging tool to aid in treatment planning of OPSCC, as rates of RPLN and nodal metastasis are consistent with those reported in the literature. Advanced T and N stage are associated with a greater odds ratio of being RPLN positive by PET-CT imaging.

While the authors appropriately conclude that insulin treatment did not show any benefit in regard to the specified outcomes, it is not clear if insulin therapy is associated with harm, and not hyperglycaemia itself. Arch Dis Child Fetal Neonatal Ed. 2022; 107 (3): 269 - 280. doi: 10.1136/archdischild-2020-321449 2 Patidar N, Rath CP, Rao S, Patole S.

Hyperglycaemia remains a common occurrence in the first weeks of life of very pre-term or very low birth weight (VLBW) infants. [Extracted from the article]

Background: It is challenging to provide optimum nutrition in low-birth-weight (LBW) infants with short-bowel syndrome (SBS) and ostomy. This study aims to evaluate the clinical course of LBW infants with SBS and ostomy in response to enteral feeds, recognize characteristics associated with achievement of enteral autonomy prior to reanastomosis, and evaluate associated short-term outcomes.Methods: A retrospective analysis of 52 LBW neonates with intestinal failure (IF) caused by SBS and ostomy treated in a neonatal intensive care unit from 2012 to 2018 was performed. Clinical characteristics and short-term outcomes were studied in relation to the location of the ostomy and the success with enteral feeding achieved prior to reanastomosis.Results: Of the 52 infants with SBS, jejunostomy, ileostomy, and colostomy were present in 9, 40, and 3 infants, respectively. Fourteen (26.92%) infants achieved enteral autonomy transiently, and 7 (13.46%) sustained until reanastomosis. All 9 infants with jejunostomy were parenteral nutrition dependent, compared with 22 with ileostomy and none with colostomy (P = 0.002). Infants who achieved enteral autonomy showed lower incidence of cholestasis (P = 0.038) and better growth velocity (P = 0.02) prior to reanastomosis.Conclusions: A minority of LBW infants with SBS and ostomy achieved enteral autonomy prior to reanastomosis. Distal ostomy (ileostomy and colostomy), reduced cholestasis, and better growth were associated with achievement of enteral autonomy. Our report highlights the challenges in establishing enteral autonomy in LBW infants with IF and ostomy, and the feasibility of that approach in a minority of patients, with tangible benefits.

Objective: To compare the efficacy of monofilament suture, braided polyester thread, and 5 mm tape suture in reducing preterm birth (PTB).Study design: Women who received a cerclage at Touro Infirmary, New Orleans, LA, USA, between 1 January, 2011 and 31 December, 2016 were identified using ICD-9/10 codes. All charts were reviewed for demographic and obstetrical variables including gestational age (GA) at delivery.Results: Of 145 women who received a cerclage, 36 were excluded due to incomplete charts leaving 109 for analysis. There was no significant difference in gestational age at cerclage placement or delivery among women with monofilament, braided, or 5 mm tape cerclages (p = .936 and p = .919, respectively) nor was there a difference in the proportion who delivered at ≥32, 34, or 37 weeks across groups with differing cerclage material (p = .270, p = .275, and p = .419, respectively). There was no difference in GA at delivery for patients who received 17-OHP compared to those who did not (p = .362). There were also no differences with respect to birth outcomes such as birthweight (p = .938), Apgar scores (p = .477, p = .430) or neonatal intensive care admission rates (NICU) (p = .304). Analysis revealed no difference in characteristics between groups including history of PTB or indication for removal (p = .371, p = .317).Conclusion: We found no difference in pregnancy prolongation when comparing different suture material used for indicated cerclages. We also found no differences with respect to rates of maternal infection or adverse neonatal outcomes among groups.RationaleThis study was conducted to evaluate the efficacy of different suture materials in increasing gestational age at delivery and reducing preterm birth.

The objective of this study was to determine if the use of weight-based criteria to screen for asymptomatic hypoglycemia is consistent with using percentile curves to determine small and large for gestational age status. A retrospective chart review of 892 term infants in the normal nursery was performed. The degree of agreement in screening recommendations between weight-based criteria and the Lubchenco, Oken, and Olsen percentile curves was determined using Cohen's κ and McNemar's test. Agreement was lower between Lubchenco and Olsen or Oken (0.470, 0.509, respectively) than with weight-based criteria (Lubchenko = 0.532; Oken = 0.566; and Olsen = 0.582). Weight-based criteria recommended screening 12% and 7% fewer patients than Lubchenko and Oken, respectively (P <.001), but was equally likely to screen infants as Olsen (P =.579). Simple weight-based criteria for asymptomatic hypoglycemia screening can identify infants at risk for hypoglycemia in a manner consistent with current guidelines. [ABSTRACT FROM AUTHOR]

Importance: When a neonate's sucking, swallowing, and breathing are disorganized, oropharyngeal aspiration often occurs and results in illness, developmental problems, and even death. Occupational therapists who work in the neonatal intensive care unit (NICU) need to identify neonates who are at risk for aspirating so they can provide appropriate treatment. Objective: To ascertain whether client factors and performance skills of infants ages 0--6 mo during occupational therapy feeding evaluations are related to results of videofluoroscopic swallowing studies (VFSSs). Design: Retrospective chart reviews. Setting: 187-bed NICU in a nonprofit teaching hospital. Participants: A purposive sample of 334 infants ages 0--6 mo, ≥33 wk gestational age at birth, admitted to a Level II, III, or IV NICU as defined by the American Academy of Pediatrics. Outcomes and Measures: Neonates were administered a feeding evaluation by an occupational therapist and a VFSS by a speech-language pathologist, which yielded information about client factors and performance skills. Results: Signs and symptoms of aspiration on the evaluations were significantly associated with VFSS results. Of 310 patients, 79 had silent aspiration. Of 55 infants who demonstrated no aspiration symptoms during the feeding evaluation, 45% demonstrated aspiration symptoms on the VFSS, and 55% aspirated on the VFSS but demonstrated no symptoms of aspiration. Conclusions and Relevance: Aspiration among infants occurs inconsistently and depends on client factors, contexts, and environments. Occupational therapists are encouraged to assess an infant's feeding over several sessions to obtain a more accurate picture of the infant's feeding status. [ABSTRACT FROM AUTHOR]

Objective: To compare postdischarge growth, adiposity and metabolic outcomes of appropriate for gestational age (AGA) versus small for gestational age (SGA) premature infants fed an exclusive human milk (HM)-based diet in the neonatal intensive care unit.Design: Premature infants (birth weight ≤1250 g) fed an exclusive HM-based diet were examined at 12-15 months corrected gestational age (CGA) (visit 1) for anthropometrics, serum glucose and non-fasting insulin, and at 18-22 months CGA (visit 2) for body composition by dual-energy X-ray absorptiometry.Results: Of 51 children, 33 were AGA and 18 were SGA at birth. The SGA group had weight gain (g/day) equal to AGA group during the follow-up period. SGA had a significantly greater body mass index (BMI) z-score gain from visit 1 to visit 2 (0.25±1.10 vs -0.21±0.84, p=0.02) reflecting catch-up growth. There were no significant differences in total fat mass (FM) and trunk FM between groups. SGA had significantly lower insulin level (5.0±3.7 vs 17.3±15.1 µU/mL, p=0.02) and homeostatic model of assessment-insulin resistance (1.1±0.9 vs 4.3±4.1, p=0.02). Although regional trunk FM correlated with insulin levels in SGA (r=0.893, p=0.04), they had lower insulin level compared with AGA and no difference in adiposity.Conclusions: SGA premature infants who received an exclusive HM-based diet exhibited greater catch-up growth without increased adiposity or elevated insulin resistance compared with AGA at 2 years of age. An exclusive HM-based diet may improve long-term body composition and metabolic outcomes of premature infants with ≤1250 g birth weight, specifically SGA. [ABSTRACT FROM AUTHOR]

Lung omics signatures in a bronchopulmonary dysplasia and pulmonary hypertension-like murine model. Am J Physiol Lung Cell Mol Physiol 315: L734-L741, 2018. First published July 26, 2018; doi:10.1152/ajplung.00183.2018.--Bronchopulmonary dysplasia (BPD), the most common chronic lung disease in infants, is associated with long-term morbidities, including pulmonary hypertension (PH). Importantly, hyperoxia causes BPD and PH; however, the underlying mechanisms remain unclear. Herein, we performed highthroughput transcriptomic and proteomic studies using a clinically relevant murine model of BPD with PH. Neonatal wild-type C57BL6J mice were exposed to 21% oxygen (normoxia) or 70% oxygen (hyperoxia) during postnatal days (PNDs) 1-7. Lung tissues were collected for proteomic and genomic analyses on PND 7, and selected genes and proteins were validated by real-time quantitative PCR and immunoblotting analysis, respectively. Hyperoxia exposure dysregulated the expression of 344 genes and 21 proteins. Interestingly, hyperoxia downregulated genes involved in neuronal development and maturation in lung tissues. Gene set enrichment and gene ontology analyses identified apoptosis, oxidoreductase activity, plasma membrane integrity, organ development, angiogenesis, cell proliferation, and mitophagy as the predominant processes affected by hyperoxia. Furthermore, selected deregulated proteins strongly correlated with the expression of specific genes. Collectively, our results identified several potential therapeutic targets for hyperoxia-mediated BPD and PH in infants. [ABSTRACT FROM AUTHOR]

Objective The objective of this study was to compare complications and mortality in neonates with hypoxic ischemic encephalopathy (HIE) on extracorporeal membrane oxygenation (ECMO) who did and did not receive therapeutic hypothermia (TH). Study Design The Extracorporeal Life Support Organization registry was queried from 2005 to 2013 to identified infants with HIE. Infants ≤30 days of age with HIE on respiratory ECMO were included. Fisher's exact test and the Wilcoxon's rank-sum test were used to compare neonates with and without TH. Logistic regression was used to examine the association of TH with complications and mortality. Results There were no difference between neonates with HIE who did (n = 78) and did not (n = 109) receive TH in demographics, severity of illness, complications, and mortality (p = 0.21). Conclusion No differences in complications or mortality in neonates with HIE and respiratory ECMO were observed between those who did and did not receive TH. We suggest that for neonates requiring respiratory ECMO who also have HIE, TH is not contraindicated. [ABSTRACT FROM AUTHOR]

Uncivil behavior by a faculty member or student can threaten a classroom environment and make it less conducive to learning. The aim of this study was to explore faculty behaviors that dental faculty and students perceive to be uncivil when exhibited in the classroom and clinic. In 2015, all faculty, administrators, and students at a single academic dental institution were invited to participate in an electronic survey that used a five-point Likert scale for respondents to indicate their agreement that 33 faculty behaviors were uncivil. Response rates were 49% for faculty and 59% for students. Significant differences were found between student and faculty responses on 22 of the 33 behavioral items. None of the three category composite scores differed significantly for students compared to faculty respondents. The category composite scores were not significantly associated with gender, ethnicity, or age for faculty or students. Overall, this study found significant differences between students and faculty about perceived uncivil faculty behaviors, though not for categories of behaviors. [ABSTRACT FROM AUTHOR]
