Background: Delivery room resuscitation of very low birth weight infants can involve use of endotracheal or intravenous epinephrine. Data of the past 19 years were reviewed to identify the usage of epinephrine in delivery room and identify characteristics of these babies.
Methods: Neonates with ≤1500g birthweight from January 1996 to August 2014 were reviewed. Infants born alive and admitted to NICU were eligible. Characteristics such as demographics, survival and outcomes were recorded. Variables significant at p≤0.1 among neonates receiving epinephrine were further analyzed via multiple logistic regressions.
Results: Out of 5868 eligible neonates, 416 (7%) received epinephrine in the delivery room. The infants who received epinephrine were of lower estimated gestational age (25 vs. 28wk) and lower birth weight (746 vs. 980g). Gender, race and mode of delivery were comparable between the two cohorts. Survival was higher in non-epinephrine group (89.4 vs. 61.1%). Bacterial infection (24.3 vs. 18.4%) and combined grade 3 and 4 intraventricular hemorrhage (18.4 vs. 8.4%) were higher in epinephrine group. Use of epinephrine in the delivery room was associated with decreased survival even after controlling for birth weight, gestational age and low Apgar scores [Odd ratio - 0.48 with 95% CI (0.37-0.62), p<0.001].
Conclusion: Neonates with lower birth weight and younger gestational age were more likely to receive epinephrine during resuscitation at birth. Use of epinephrine in delivery room was associated with lower survival and severe intraventricular hemorrhage among very low birth weight infants.

Reducing Greenhouse Gas Emissions and Modifying Nitrous Oxide Delivery at Stanford: Observational, Pilot Intervention Study.

Stanford Hospital, Stanford, CA, United States.
Background: Inhalational anesthetic agents are a major source of potent greenhouse gases in the medical sector, and reducing their emissions is a readily addressable goal. Nitrous oxide (NO) has a long environmental half-life relative to carbon dioxide combined with a low clinical potency, leading to relatively large amounts of NO being stored in cryogenic tanks and H cylinders for use, increasing the chance of pollution through leaks. Building on previous findings, Stanford Health Care's (SHC's) NO emissions were analyzed at 2 campuses and targeted for waste reduction as a precursor to system-wide reductions.

Background: Premature births has imposed substantial burdens on medical resources. Consequently, a specialized team was established and a model focused on early intervention, namely the Delivery Room Intensive Care Unit (DICU) emphasizing "care, support, and treatment" was introduced and its impact on the morbidity and mortality outcomes of newborns was assessed. Additionally, we aimed to develop a nomogram model for predicting the risk of intraventricular hemorrhage (IVH) in preterm infants.

Serial macromolecular crystallography has become a powerful method to reveal room temperature structures of biological macromolecules and perform time-resolved studies. ID29, a flagship beamline of the ESRF 4th generation synchrotron, is the first synchrotron beamline in the world capable of delivering high brilliance microsecond X-ray pulses at high repetition rate for the structure determination of biological macromolecules at room temperature. The cardinal combination of microsecond exposure times, innovative beam characteristics and adaptable sample environment provides high quality complete data, even from an exceptionally small amount of crystalline material, enabling what we collectively term serial microsecond crystallography (SµX).

: The development of a five-in-one vaccine microneedle patch (five-in-one MN patch) aims to address challenges in administering vaccines against Diphtheria (DT), Tetanus (TT), Pertussis (wP), Hepatitis B (HBsAg), and type b (Hib). Combining multiple vaccines into a single patch offers a novel solution to improve vaccine accessibility, stability, and delivery efficiency, particularly in resource-limited settings. : The five-in-one MN patch consists of four distinct microneedle arrays: DT and TT vaccines are coated together on one array, while wP, HepB, and Hib vaccines are coated separately on individual arrays.

: Supersaturating drug delivery systems (SDDSs) have gained significant attention as a promising strategy to enhance the solubility and bioabsorption of Biopharmaceutics Classification System (BCS) II drugs. To overcome challenges associated with polymer-based amorphous SDDS (aSDDS), coamorphous (CAM) systems have emerged as a viable alternative. Among them, "drug-drug" CAM (ddCAM) systems show considerable potential for combination drug therapy.
