Abstract Nucleated red blood cells (NRBCs) have been studied in critically ill and injured patients as a predictor of increased in-hospital mortality and poor clinical outcomes. While prior studies have demonstrated the prognostic power of NRBCs in the critical patient, there has been a paucity of literature available describing their value as a prognostic indicator in the severely burned patient. This retrospective observational study was conducted from 2012 to 2017. Inclusion criteria for this study included all burn patients with total body surface area > 10% who were aged ≥ 15 years. Demographic and clinical data were collected from the electronic medical record system. Data analysis consisted of descriptive and comparative analysis using SPSS. Two hundred and nineteen patients (17.5%) met inclusion criteria with 51 (23.3%) patients positive for NRBCs. The presence of NRBCs had an increased mortality rate with an odds ratio of 6.0 (P = .001; 2.5, 14.5); was more likely to appear in older patients (P < .001); and was associated with increased hospital length of stay (P < .001), injury severity scores (P < .001), and complications. The presence of NRBCs even at the low concentrations reported in our study showed a 6-fold increase in the rate of mortality. With the current improvements in burn care leading to higher survival rates, the need to improve upon the numerous models that have been developed to predict mortality in severe burn patients is clear given the significantly increased risk of death that the presence of NRBCs portends.

Abstract During the Covid-19 pandemic, hospital systems delayed or halted elective surgeries and outpatient care, profoundly disrupting reconstructive burn treatment ranging from surgery to postoperative therapy. This study aims to characterize burn patients’ perspectives on reconstructive surgery during Covid-19. A 12-component questionnaire to burn patients awaiting reconstructive surgery at a single ABA verified Burn Center was administered. Responses regarding willingness to undergo reconstruction, perceived medical and personal impacts of Covid-19, and perspectives on telehealth were gathered. Surveys were administered to patients/caregivers over the phone in English and Spanish. Inclusion criteria consisted of burn patients who had elective reconstructive surgeries delayed or canceled as a result of the pandemic. 51 patients met our inclusion criteria. Of those, 23 patients responded to our survey (45%). Average patient age was 23, 43% were male, and a majority (52%) were pediatric. 22 (96%) patients were willing to undergo reconstruction during the Covid-19 pandemic, despite a perceived increased risk. 43% disagreed or strongly disagreed that telehealth adequately enabled communication with their burn care provider. 78% agreed or strongly agreed that they felt more susceptible to Covid-19 as burn patients. 83% agreed or strongly agreed that the Covid-19 pandemic had created stressors specifically related to their burn care. The majority of patients expressed a strong desire to return to surgical and therapeutic care delayed by Covid-19. Patients reported feeling especially vulnerable to the Covid-19 pandemic as burn patients, and cited difficulty obtaining care and financial stressors as the main causes.

Objective The study aimed to assess the association of nucleated red blood cells (NRBC), a surrogate of intrauterine hypoxia, and elevated pulmonic vascular resistance (E-PVR) and oxygen requirement after minimally invasive surfactant therapy (MIST). Study Design Retrospective study of a cohort of preterm neonates that received MIST in a single unit. Results NRBC were measured in 65 of 75 (87%) neonates administered MIST during the period. In total, 22 of 65 (34%) infants had pre-MIST echocardiography (ECHO).Neonates with elevated NRBC (predefined as >5 × 109/L, n = 16) required higher post-MIST fraction of inspired oxygen (FiO2) than neonates with normal NRBC (<1 × 109/L, n = 17; FiO2 = 0.31 ± 0.10 and 0.24 ± 0.04, respectively, p = 0.02).NRBC correlated positively with % of time in right to left ductal shunt (r = 0.51, p = 0.052) and inversely with right ventricular stroke volume (r = −0.55, p = 0.031) and time to peak velocity to right ventricular ejection time ratio (r = −0.62, p < 0.001). Conclusion Elevated NRBC are associated with elevated FiO2 after MIST and elevated E-PVR. Intrauterine hypoxia may impact postnatal circulatory adaptations and oxygen requirement. Key Points

Heart regeneration is negligible in humans and mammals but remarkable in some ectotherms. Humans and mammals lack nucleated red blood cells (NRBCs), while ectotherms have sufficient NRBCs. This study used Bufo gargarizan gargarizan, a Chinese toad subspecies, as a model animal to verify our hypothesis that NRBCs participate in myocardial regeneration. NRBC infiltration into myocardium was seen in the healthy toad hearts. Heart needle-injury was used as an enlarged model of physiological cardiomyocyte loss. It recovered quickly and scarlessly. NRBC infiltration increased during the recovery. Transwell assay was done to in vitro explore effects of myocardial injury on NRBCs. In the transwell system, NRBCs could infiltrate into cardiac pieces and could transdifferentiate toward cardiomyocytes. Heart apex cautery caused approximately 5% of the ventricle to be injured to varying degrees. In the mildly to moderately injured regions, NRBC infiltration increased and myocardial regeneration started soon after the inflammatory response; the severely damaged region underwent inflammation, scarring, and vascularity before NRBC infiltration and myocardial regeneration, and recovered scarlessly in four months. NRBCs were seen in the newly formed myocardium. Enzyme-linked immunosorbent assay and Western blotting showed that the levels of tumor necrosis factor-α, interleukin- 1β, 6, and11, cardiotrophin-1, vascular endothelial growth factor, erythropoietin, matrix metalloproteinase- 2 and 9 in the serum and/or cardiac tissues fluctuated in different patterns during the cardiac injury-regeneration. Cardiotrophin-1 could induce toad NRBC transdifferentiation toward cardiomyocytes in vitro. Taken together, the results suggest that the NRBC is a cell source for cardiomyocyte renewal/regeneration in the toad; cardiomyocyte loss triggers a series of biological processes, facilitating NRBC infiltration and transition to cardiomyocytes. This finding may guide a new direction for improving human myocardial regeneration.
