Unveiling triglyceride levels in preterm neonates: a study to guide targeted monitoring.

BACKGROUND: Mixed lipid emulsion (MLE), most commonly soybean, medium chain triglycerides, olive, and fish oils (SMOF), has replaced soybean-based lipid emulsions in many neonatal intensive care units. Only a few studies report the triglyceride (TG) trajectory in neonates receiving MLE. We designed a study to compare TG levels in neonates receiving MLE stratified by gestational age (GA), birth weight (BW), and growth restriction status. METHODS: We included neonates born at <32 weeks GA or with BW <1500 gm. SMOF is started on admission, and plasma TG levels are measured 24 hours after 2 gm/kg/day and 24 hours after 3 gm/kg/day. TG levels were compared across groups defined by GA (<28 weeks vs. 328 weeks), BW (<1000 gm vs. 31000 gm), and small for GA (SGA) vs. appropriate plus large for GA groups using the Wilcoxon rank sum test. RESULTS: From 2018 to 2021, 427 infants met the inclusion criteria. TG levels were significantly higher in neonates with GA <28 weeks, BW <1000 grams, and SGA with a notable broad distribution of TG levels. Logistic regression analysis confirmed SGA and BW as significant independent predictors of hypertriglyceridemia after SMOF at 2 gm/kg/day and 3 gm/kg/day, respectively. CONCLUSIONS: The study emphasizes the importance of TG monitoring for neonates with GA <28 weeks, BW <1000 grams, and SGA. Conversely, it is advisable to individualize TG monitoring for infants with GA>28 weeks, BW>1000 grams, and non-SGA status. Prospective studies with larger sample sizes are warranted to validate our findings.

A Improving Birth-dose Hepatitis-B Vaccination in a Tertiary Level IV Neonatal Intensive Care Unit.

Background: Perinatal hepatitis B is a global public health concern. To reduce perinatal hepatitis B and its complications, the Hepatitis B vaccine (HBV) is recommended by the New York State Department of Health and Advisory Committee on Immunization Practices within 24 hours of life for infants born with a birth weight ≥2000 g. Infants admitted to the neonatal intensive care unit (NICU) weighing over 2000 g missed their birth dose HBV frequently, which prompted the implementation of a quality improvement initiative to increase birth dose HBV immunization in a level IV NICU in New York. Methods: May 2019 to April 2021 baseline data showed the birth dose HBV rate of infants born ≥2000 g at 24% and 31% within 12 and 24 hours, respectively. The multidisciplinary QI team identified barriers using an Ishikawa cause-and-effect diagram. Our interventions included multidisciplinary collaboration, electronic medical record reminders, education, posters, and improved communication between staff and parents. We aimed to achieve a 25% improvement from the baseline. Results: After 19 months of QI interventions (four Plan-Do-Study-Act cycles), the rate of administering birth dose HBV within 12 hours of life increased from 24% to 56% and within 24 hours from 31% to 64%. Process measure compliance improved, exceeding the 25% target, and showed sustained improvement. Conclusion: This QI initiative improved the rate of eligible infants receiving HBV within the first 24 hours of life in the NICU. This work can serve as a model for other healthcare institutions to improve HBV immunization rates in NICUs.

Incidence of Complications Associated with Parenteral Nutrition in Preterm Infants < 32 Weeks with a Mixed Oil Lipid Emulsion vs a Soybean Oil Lipid Emulsion in a Level IV Neonatal Intensive Care Unit.

BACKGROUND: Parenteral nutrition (PN) is crucial for the improvement of long-term outcomes in very low birth weight (VLBW) neonates. Lipid injectable emulsions are a key component of PN, as they contain essential fatty acids and provide energy critical for brain growth. Prolonged administration increases risk of intestinal failure-associated liver disease, including cholestasis, and other complications. METHODS: This is a retrospective, quasi-experimental cohort study of 215 VLBW neonates. The primary outcome was a change in direct bilirubin concentration. Secondary outcomes included change in total bilirubin concentration and incidences of cholestasis and other disease states associated with PN and prematurity. Cholestasis was defined as direct bilirubin ≥ 1.0 mg/dL with total bilirubin < 5.0 mg/dL or direct bilirubin > 20% of total bilirubin with total bilirubin > 5.0 mg/dL. RESULTS: Change in direct bilirubin concentration was not different between groups. Incidence of cholestasis was not different between groups per charted diagnosis or per study definition. Non-stage-0 retinopathy of prematurity, bronchopulmonary dysplasia, sepsis, and necrotizing enterocolitis were all lower in the mixed oil lipid emulsion group, which remained significant after adjustment for differences in gestational age, birth weight, and PN duration. CONCLUSIONS: Although mixed oil lipid emulsion was not found to be associated with a lower risk of cholestasis, it may decrease risks of other disease states associated with PN therapy.

Hospital emergency preparedness: Push-POD operation and pharmacists as immunizers.

OBJECTIVE: To describe Montefiore Medical Center's participation in a point-of-distribution (POD) exercise in which pharmacists were drilled on the ability to provide immunizations in the face of an emergency. SETTING: New York City on October 9, 2007. SUMMARY: Rapid and appropriate response to a terrorism event can limit morbidity and mortality. After the events of September 11, 2001, the New York City Department of Health and Mental Hygiene (DOHMH) recognized the need to develop a uniform procedure in the case of a potential health disaster. During the fiscal year occurring between September 1, 2006, and August 31, 2007, DOHMH requested that all citywide hospitals participate in a POD drill. All participating hospitals were required to have a team of five health professionals, including one pharmacist, one physician, two nurses, and another member of the institution. The drill was to be conducted within a 4-hour interval to simulate a situation of mass prophylaxis using influenza as a surrogate vaccine or pharmaceutical agent needed in the event of a public health emergency. MAIN OUTCOME MEASURE: Number of health care workers immunized in 4-hour period. RESULTS: During the 4-hour period, the team was able to immunize 942 heath care workers. Predicting a 24/7 operation in the event of a biological terrorism event, the Push-POD operation would have the capacity to immunize 12,000 health care workers-the approximate population of the hospital-in 48 hours. This exercise was replicated for the 2008 influenza program, and the results were identical. CONCLUSION: By allowing pharmacists to expand their scope of practice, New York State will inevitably see a drastic improvement in its adult immunization rates for influenza and pneumococcal vaccinations through greater public awareness and expanded vaccine access.
