The objective of this study is to determine the true incidence early neonatal hypoglycemia and confirm potential risk factors.The was conducted at tertiary Medical Center in Israel, between June September 2014. First blood glucose concentrations all infants admitted nursery were measured using a "point care" analyzer (Accu-Chek). We recorded factors for such as birth weight, gestational age, maternal diabetes demographics analyzed their association with two cutoffs: 40 47 mg/dl.Of 4000...

There has not been an extensive comparison of CRP and ESR in ulcerative colitis (UC), thus, we aimed to explore their utility UC.Four previously enrolled cohorts 451 children with UC were utilized, all including laboratory, clinical endoscopic data. A longitudinal analysis was performed on prospectively collected data 75 children. Disease activity captured by both global assessment pediatric index (PUCAI).The best thresholds differentiate quiescent, mild, moderate severe disease activity,...

OBJECTIVES: To assess infection rates predischarge and postdischarge in breast milk–fed newborns with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–positive mothers who were separated postdelivery from their discharged the hospital. Also, we aim to evaluate breastfeeding postdischarge. METHODS: Nasopharyngeal swabs for SARS-CoV-2 obtained symptomatic high-risk women delivery room. Mothers positive test results newborns. Newborns screened within 48 hours of delivery,...

Abstract Background Acute kidney injury (AKI) in neonates is associated with increased morbidity and mortality, longer hospitalization, a higher risk for future damage. Caffeine treatment has reportedly been decreased AKI occurrence. However, previous studies lack uniformity regarding dosage timing of administration. This study aimed to assess incidence very-low-birth-weight (VLBW) preterm infants (< 1500 g) treated early high-dose caffeine identify factors AKI. Methods A retrospective...

Abstract Background Neonatal intensive care unit (NICU) admission among term neonates is a rare event. The aim of this study was to the association NICU on risk long-term childhood mortality. Methods A single-center case–control retrospective between 2005 and 2019, including all in-hospital ≥ 37 weeks’ gestation singleton live-born neonates. center perinatal database linked with birth death certificate registries Israeli Ministry Internal Affairs. primary mortality throughout 15-year...

Oxygen saturation in arterial blood (SaO₂) provides information about the performance of respiratory system. Non-invasive measurement SaO₂ by commercial pulse oximeters (SpO₂) make use photoplethysmographic pulses red and infrared regions utilizes different spectra light absorption oxygenated de-oxygenated hemoglobin. Because scattering optical path-lengths differ between two wavelengths, require empirical calibration which is based on extracted blood. They are still prone to error, because...

Objective Intravenous lipid infusions improve both short- and long-term outcomes of premature neonates. However, prolonged infusion lipids has been implicated in the development parenteral nutrition-associated cholestasis (PNAC). We speculated that multicomponent SMOFlipid would be hepatoprotective against PNAC. Study Design This is a retrospective review comparing incidence severity direct hyperbilirubinemia preterm infants <1,500 g who were hospitalized for minimum 2 weeks during...

Objective: Neonatal intensive care unit (NICU) admission among term neonates is associated with significant morbidity and mortality, as well high healthcare costs. A comprehensive NICU risk assessment using an integrated statistical approach for this rare event may be used to build a calculation algorithm group of prior delivery. Methods: single-center case−control retrospective study was conducted between August 2005 December 2019, including in-hospital singleton live born neonates, at ≥37...

This study aimed to test whether neonatal hypoglycemia (NH) is more common in infants with polycythemia (NP).This a retrospective based on universal screening of NH and targeted for NP. Polycythemia was defined as venous hematocrit ≥ 65%. whole blood glucose (BG) concentration < 48 mg/dL (measured using "point-of-care" analyzer [Accu-Chek]).The population consisted 119 consecutive term polycythemic 117 controls. There were no significant differences between the two groups perinatal...

Scalloping of duodenal folds noted on esophagogastroduodenoscopy (EGD) has been associated with various illnesses including celiac disease (CD). The aim the present study was to examine frequency scalloping in pediatric patients undergoing EGD and assess its significance diagnosis CD. We also evaluated association histopathology serology subgroup patients.All children (0-18 years) who underwent at Shaare Zedek Medical Center for any reason during a 2.5-year period were retrospectively...

Neonatal asphyxia is often associated with hepatic injury. We hypothesized that this might lead to increased bilirubin concentrations.Term neonates admitted between January 2015 and April 2017 who remained hospitalized for ≥ 4 days had serial serum concentrations recorded were divided into those neonatal encephalopathy (NE) controls. Serial during the first of life compared groups.Twenty-nine NE 84 age-matched controls identified. Mean total babies significantly lower than throughout life....

Objective Platelet function parameters can be predictive of several adult diseases and their severity. However, few studies report on the association between platelet indices neonatal diseases, specifically necrotizing enterocolitis (NEC). The objective this study is to investigate whether are associated with NEC diagnosis NEC-related mortality. Study Design We retrospectively examined records from infants admitted intensive care unit a NEC, verified by presence pneumatosis X-ray or...

Objective Normal initial blood glucose values in healthy newborns are not well defined and subject to controversy. Despite substantive research, there is no single value of that can be used with certainty safety newborns, thus various protocols cutoffs have been proposed. Study Design We sought characterize the normal levels a large cohort neonates admitted well-baby nursery Shaare Zedek Medical Center. The were measured point care (POC) glucometer (Accu-Chek Performa) within 180 minutes...

Conventional magnetic resonance imaging (MRI) neuroimaging of infants is complicated by the need to transport outside neonatal intensive care unit (NICU), often distant areas hospital.The main aim this study was evaluate and compare scoring images from a novel 1T MRI, which enables within NICU, with those conventional MRI.The second document improved expediency, thereby greater patient safety, as reflected decreased time.Thirty premature (mean gestational age: 28.8 ± 2.1 weeks) were scanned...
