ABSTRACT
A newborn male infant was pale, hypotonic, and had respiratory distress after delivery. Venous cord blood gas revealed a severe metabolic acidosis. His initial examination was consistent with moderate encephalopathy and laboratory testing uncovered severe congenital anaemia (haematocrit 0.127 L/L). He met the clinical criteria for therapeutic hypothermia (TH) and required red blood cell transfusions, but due to the severity of his anaemia, an exchange transfusion was favoured to prevent transfusion-associated circulatory overload. There are no previous reports of these procedures completed in tandem, but the benefits were perceived to outweigh the risks. During the 72 hours of TH, the infant received an isovolumetric partial exchange transfusion and tolerated both treatments without any adverse clinical events.Kleihauer-Betke testing detected a massive chronic fetomaternal haemorrhage with 475 mL (164 mL/kg) of blood. A brain MRI completed prior to discharge was normal. At 6 months of age, he is growing and developing normally.

INTRODUCTION: Nearly a quarter of active duty service members identified as food insecure in a 2022 Department of Defense report. Food insecurity impacts military readiness, retention, and recruitment. The Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a federal food supplementation program that can mitigate food insecurity for service members with children less than 5 years of age. To date, there is a lack of standardized screening for WIC eligibility or enrollment for service members and their families. This project sought to evaluate WIC awareness and enrollment as well as the prevalence of food insecurity at Walter Reed National Military Medical Center. MATERIALS AND METHODS: A 26-question survey was developed to assess WIC awareness, source of WIC information, food insecurity, and nutritional insecurity. Our team developed and utilized a novel WIC screening algorithm to rapidly screen families for WIC eligibility. These tools were administered to families presenting for care at the Walter Reed National Military Medical Center pediatrics and obstetric outpatient clinics during the month of July 2022. This study was approved by the institutional review board at Walter Reed. RESULTS: A total of 108 (25%) of the 432 surveyed participants were eligible for WIC, with odds of WIC eligibility increasing for lower-ranking and younger service members. Of the 432 participants, 354 (81.9%) were aware of WIC. Enlisted service members were more likely than officers to know about WIC (P = 0.03), and of the 354 participants aware of WIC, a higher proportion of enlisted rank respondents learned about WIC from a military source (P = 0.01). Among the 108 participants eligible for WIC, only 38 (35.2%) reported being enrolled in WIC. Among WIC-eligible respondents who knew about WIC, being enrolled in the WIC program was not associated with rank, branch of service, sponsor gender, or sponsor age. CONCLUSIONS: Despite proven efficacy, WIC remains an underutilized resource for eligible military families. Our results show that a standardized screening approach at Walter Reed National Military Medical Center increased identification of WIC-eligible active duty service members by 180%, with approximately $150,000 a year in increased food supplementation benefits. Military healthcare and readiness leaders should embrace efforts to increase knowledge of, referral to, and enrollment in WIC to increase family health, well-being, and military family readiness.
ABSTRACT
Sedatives are suspected contributors to neurologic dysfunction in PICU patients, to whom they are administered during sensitive neurodevelopment. Relevant preclinical modeling has largely used comparatively brief anesthesia in infant age-approximate animals, with insufficient study of repetitive combined drug administration during childhood. We hypothesized that childhood neurodevelopment is selectively vulnerable to repeated treatment with benzodiazepine and opioid. We report a preclinical model of combined midazolam and morphine in early childhood age-approximate rats. DESIGN: Animal model. SETTING: Basic science laboratory. SUBJECTS: Male and female Long-Evans rats. INTERVENTIONS: Injections of morphine + midazolam were administered twice daily from postnatal days 18-22, tapering on postnatal days 23 and 24. Control groups included saline, morphine, or midazolam. To screen for acute neurodevelopmental effects, brain homogenates were analyzed by western blot for synaptophysin, drebrin, glial fibrillary acidic protein, S100 calcium-binding protein B, ionized calcium-binding adaptor molecule 1, and myelin basic proteins. Data analysis used Kruskal-Wallis with Dunn posttest, with a p value of less than 0.05 significance. MEASUREMENTS AND MAIN RESULTS: Morphine + midazolam and morphine animals gained less weight than saline or midazolam (p ≤ 0.01). Compared with saline, morphine + midazolam expressed significantly higher drebrin levels (p = 0.01), with numerically but not statistically decreased glial fibrillary acidic protein. Similarly, morphine animals exhibited less glial fibrillary acidic protein and more S100 calcium-binding protein B and synaptophysin. Midazolam animals expressed significantly more S100 calcium-binding protein B (p < 0.001) and 17-18.5 kDa myelin basic protein splicing isoform (p = 0.01), with numerically increased synaptophysin, ionized calcium-binding adaptor molecule 1, and 21.5 kDa myelin basic protein, and decreased glial fibrillary acidic protein. CONCLUSIONS: Analysis of brain tissue in this novel rodent model of repetitive morphine and midazolam administration showed effects on synaptic, astrocytic, microglial, and myelin proteins. These findings warrant further investigation because they may have implications for critically ill children requiring sedation and analgesia.
