Context: Delayed thyrotropin (TSH) elevation (dTSH) is defined as elevated TSH at the second neonatal screening (after normal TSH levels at the initial screening) in premature, low-birth-weight, and ill newborns, mostly in the neonatal intensive care unit (NICU) setting. The pathogenesis of dTSH is elusive. Objective: To identify the risk factors for dTSH development among newborns in the NICU. Design, Setting, and Patients: A retrospective medical record review of neonates with dTSH was conducted in eight university-affiliated NICUs. Two controls were selected for each patient, matched for sex and birth weight. The risk factors for dTSH were identified by univariate analysis, followed by multivariate analysis. Main Outcome Measures: Maternal variables, types of NICU treatments and procedures, syndromes, and various medical conditions were compared between dTSH patients and their matched controls. Results: We enrolled 100 dTSH patients and 200 matched controls and 46 variables were compared between the two groups. Twelve risk factors for dTSH were identified on univariate analysis: cesarean section, mechanical ventilation, patent ductus arteriosus (PDA), pneumothorax, and administration of cefotaxime, vancomycin, fluconazole, dopamine, ibuprofen, furosemide, insulin, and packed red blood cells. On multivariate analysis, four risk factors were identified: PDA and vancomycin, insulin, and furosemide administration. In 26 twin pairs, in which one twin had dTSH, all variables presented similarly in both twins. Conclusions: Although some variables had direct effects on pituitary–thyroid axis dysfunction, these variables, altogether, reflect the severity of the clinical conditions in the NICU, which is the common basis for dTSH.

OBJECTIVES: To follow changes in the causes of neonatal deaths in the NICU at Hadassah Medical Center, Jerusalem, Israel, over a decade; to examine trends regarding types of end-of-life-care provided (primary nonintervention, maximal intensive, and redirection of intensive care, including limitation of care and withdrawal of life-sustaining treatment); and to assess the parental role in the decision-making process given that the majority of the population is religious. METHODS: All neonates who died between 2000 and 2009 were identified. The causes and circumstances of death were abstracted from the medical records. Trends in end-of-life decisions were compared between 2 time periods: 2000–2004 versus 2005–2009. RESULTS: Overall, 239 neonates died. The leading cause of death in both study periods was prematurity and its complications (76%). Among term infants, the leading cause of death was congenital anomalies (48%). Fifty-six percent of the infants received maximal intensive care; 28% had redirection of intensive care, of whom 10% had withdrawal of life-sustaining treatment; and 16% had primary nonintervention care. Over the years, maximal intensive care decreased from 65% to 46% (P < .02), whereas redirection of care increased from 19.2% to 37.5% (P < .0005). An active parental role in the end-of-life decision process increased from 38% to 84%. CONCLUSIONS: Even among religious families of extremely sick neonates, redirection of care is a feasible treatment option, suggesting that apart from survival, quality-of-life considerations emerge as an important factor in the decision-making process for the infant, parents, and caregivers.

Background and objectives: Very low birth weight (VLBW) infants are at high risk of developing acute kidney injury (AKI), presumably secondary to low kidney reserves, stressful postnatal events, and drug exposures. Our study aimed to identify the prevalence, risk factors, and outcomes associated with AKI in VLBW infants. Study design: Records of all VLBW infants admitted to two medical campuses between January 2019 and June 2020 were retrospectively reviewed. AKI was classified using the modified KDIGO definition to include only serum creatinine. Risk factors and composite outcomes were compared between infants with and without AKI. We evaluated the main predictors of AKI and death with forward stepwise regression analysis. Results: 152 VLBW infants were enrolled. 21% of them developed AKI. Based on the multivariable analysis, the most significant predictors of AKI were the use of vasopressors, patent ductus arteriosus, and bloodstream infection. AKI had a strong and independent association with neonatal mortality. Conclusions: AKI is common in VLBW infants and is a significant risk factor for mortality. Efforts to prevent AKI are necessary to prevent its harmful effects.

There is an increasing trend of parents refusing vitamin K (VK) prophylaxis in newborns. We examined the knowledge, perceptions, cultural and religious barriers of expecting parents regarding VK prophylaxis. Questionnaires were completed by 217 participants: 151 female participants and 85% were expecting their first child. Two thirds had academic degrees, yet were ignorant regarding recommendation to provide VK (22.5%), source (15.5%), action (34%), and provision options (29%). Moreover, first-time parents had not yet decided to provide VK after birth (P<0.05). There is a need to provide expecting parents with information regarding safety, utility, and benefits of VK prophylaxis.

Background: Necrotizing enterocolitis is the leading gastrointestinal cause of morbidity and mortality in neonatal intensive care units. Despite advancements in neonatal care, the incidence of NEC remains unchanged. This study evaluated trends in NEC incidence and severity over the past decade and identified associated risk factors in our NICU population. Methods: This was a retrospective cohort study comparing the prevalence and severity of NEC among VLBW infants born before 32 weeks of gestation across the following two periods: 2012–2016 and 2017–2021. Clinical data were extracted from medical records, with NEC diagnosis and grading based on the modified Bell’s criteria. Results: A total of 299 infants were included. Those born in the later period were significantly more preterm and had lower birth weights. While the overall NEC incidence increased in the later cohort, the rate of surgical NEC was lower. Logistic regression identified hemodynamic instability requiring pressor support, late-onset sepsis, and earlier gestational age as significant risk factors for NEC. Conclusions: Although the incidence of NEC was higher in the later cohort, its severity was lower compared to the earlier cohort. These findings suggest that advancements in neonatal care and feeding protocols may contribute to improved outcomes. Early NEC stages may represent alternative intestinal or systemic conditions warranting further research for better diagnosis.
