The age-specific microbiome of children with milk, egg, and peanut allergy.

BACKGROUND: Immune regulation by gut microbiota is affected by dysbiosis and may precede food allergy onset. Prior studies lacked comparisons stratified by age and clinical phenotype. OBJECTIVE: To assess the microbiome of children with food allergy (<3 years, 3-18 years) compared with similar aged children without food allergy. METHODS: A real-world prospective cross-sectional study performed from 2014 to 2019 recruited children highly likely to have milk, egg, or peanut allergy defined by history and serum IgE or confirmed by food challenge. 16S ribosomal RNA sequencing identified stool microbial DNA. Alpha and beta diversity was compared between groups with food allergy and healthy controls stratified by age. Differential abundance for non a priori taxa was accepted at absolute fold-change greater than 2 and q value less than 0.05. RESULTS: A total of 70 patients were included (56 with food allergy and 14 healthy controls). Groups were not significantly different in age, gender at birth, race, mode of delivery, breastfeeding duration, or antibiotic exposure. Younger children with food allergy had similar alpha diversity compared with controls. Beta diversity was significantly different by age (P = .001). There was differential abundance of several a priori (P < .05) taxa (including Clostridia) only in younger children. Both a priori (including Coprococcus and Clostridia) and non a priori (q < 0.05) Acidobacteria_Gp15, Aestuariispira, Tindallia, and Desulfitispora were significant in older children with food allergy, especially with peanut allergy. CONCLUSION: Dysbiosis associates with food allergy, most prominent in older children with peanut allergy. Younger children with and without food allergy have fewer differences in gut microbiota. This correlates with clinical observations of persistence of peanut allergy and improved efficacy and safety of oral immunotherapy in younger children. Age younger than 3 years should be considered when initiating therapeutic interventions.

Fetal echocardiographic features associated with bicuspid aortic valve.

BACKGROUND: Prenatal diagnosis of bicuspid aortic valve is challenging. Bicuspid aortic valve is often associated with aortic dilation. METHODS: Fetuses with postnatally confirmed bicuspid aortic valve were gestational age-matched with normal controls. Complex lesions were excluded. Aortic valve and arch measurements by two blinded investigators were compared. RESULTS: We identified 27 cases and 27 controls. Estimated fetal weight percentile was lower in cases than controls. Seven cases had one or more significant lesions including perimembranous ventricular septal defects (n = 2), isolated annular hypoplasia (n = 2), and/or arch hypoplasia/coarctation (n = 4). Fetuses with bicuspid aortic valves had significantly smaller median z-scores of the aortic annulus (-1.60 versus -0.53, p < 0.001) and root (-1.10 versus -0.53, p = 0.040), and larger ratios of root to annulus (1.32 versus 1.21, p < 0.001), sinotubular junction to annulus (1.07 versus 0.99, p < 0.001), ascending aorta to annulus (1.29 versus 1.18, p < 0.001), and transverse aorta to annulus (1.04 versus 0.96, p = 0.023). Leaflets were "doming" in 11 cases (41%) and 0 controls (p = 0.010), "thickened" in 10 cases (37%) and 0 controls (p = 0.002). We noted similar findings in the subgroup without significant additional cardiac defects. CONCLUSIONS: The appearance of doming or thickened aortic valve leaflets on fetal echocardiogram is associated with bicuspid aortic valve. Compared to controls, fetuses with bicuspid aortic valve had smaller aortic annulus sizes (possibly related to smaller fetal size) without proportionally smaller aortic measurements, resulting in larger aortic dimension to annulus ratios. Despite inherent challenges of diagnosing bicuspid aortic valve prenatally, these findings may increase suspicion and prompt appropriate postnatal follow-up.

Barriers to Receiving Follow-up Care Among Childhood Cancer Survivors.

Little is known on why adherence to follow-up care in childhood cancer survivors (CCS) is lacking. This study characterized barriers to adherence to follow-up care among CCS, identified sociodemographic correlates of barriers, and examined whether barriers to follow-up care relate to health-related quality of life. Adult CCS (N=84) were anonymously surveyed via REDCap using the Barriers to Care Questionnaire (BCQ) and the Quality of Life Scale-Cancer Survivor (QOL-CS). Both descriptive and correlation analyses were conducted. The median BCQ total score was 88.5 (interquartile ranges:78.4 to 95.7), with the greatest barriers reported in the Skills (eg, ease of navigating the healthcare system) and Pragmatism subscales (eg, cost). There was a statistically significant correlation between the BCQ total score and the QOL-CS total score (rs=0.47, P <0.0001) and the physical, psychological, and social QOL-CS subscales (all P 's<0.05). The results found that barriers to follow-up care for CCS are mostly related to cost and appointment logistics, and that more barriers to care is associated with lower health-related quality of life among CCS. Identifying barriers to follow-up care is the first step in improving adherence, which would allow for earlier detection of late effects of cancer therapy and thereby result in reductions in morbidity and mortality.

Seroprevalence and clinical outcomes of SARS-CoV-2 in paediatric patients with rheumatic disease.

OBJECTIVES: Immunosuppressed paediatric patients with rheumatic disease (RD) may be at risk for severe or critical disease related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Data remain scarce on coronavirus disease 2019 (COVID-19) outcomes in paediatric RD patients. The aim of this study was to determine the seroprevalence of SARS-CoV-2 IgG and to describe COVID-19 outcomes in immunosuppressed paediatric RD patients. METHODS: Patients diagnosed with RD before age 18 years and treated with at least one immunosuppressive medication for at least 3 months were enrolled from a tertiary paediatric rheumatology practice in New York and also underwent routine SARS-CoV-2 IgG testing from May to November 2020. A total of 571 patients were screened and 262 were enrolled. SARS-CoV-2 IgG-positive subjects were assessed for symptoms of COVID-19 infection. SARS-CoV-2 PCR results were recorded where available. Demographic, diagnostic, medication and outcome data were collected. RESULTS: Of 262 subjects (186 female), 35 (13%) were SARS-CoV-2 IgG positive; 17 (49%) had symptoms suggestive of COVID-19. Of the 17 patients who had SARS-CoV-2 PCR testing, 11 (65%) were PCR positive, 7 of whom were IgG positive. Most SARS-CoV-2 IgG-positive subjects were not PCR tested. The most common symptoms in IgG- and/or PCR-positive subjects were fever, fatigue and cough. No SARS-CoV-2 IgG- or PCR-positive subject developed severe or critical COVID-19 or required hospitalization. CONCLUSIONS: This is the first report of clinical outcomes of SARS-CoV-2 infection and seroprevalence of SARS-CoV-2 IgG in a large cohort of paediatric RD patients. Most SARS-CoV-2 IgG-positive subjects had no symptoms of COVID-19 infection. Symptomatic subjects all had mild COVID-19 symptoms, suggesting that the risk of severe or critical COVID-19 in immunosuppressed paediatric RD patients is minimal.

Pre-hospital caloric deficits in surgical patients.

BACKGROUND: The timing, route, and amount of nutrition for surgical patients with substantial caloric deficits remain active areas of study. Current guidelines are based on in-hospital days NPO after admission to the hospital. This historic process neglects the multiple days of caloric deficit patients experience prior to hospital admission. AIM: To determine the impact of pre-hospital caloric deficit (PHCD) for surgical patients on their outcomes. METHODS: 313 patients admitted with a diagnosis of small bowel obstruction, pancreatitis, or diverticulitis were analyzed for their PHCD's. PHCD's were estimated using patient-reported days with significant emesis, and absent oral intake. Patients with PHCD's were compared to patients with no PHCD for length of stay, status on discharge, disposition, and 30-day readmission rate. RESULTS: There were 313 patients and 42% of the patients were male. The median age was 65 years. Median number of days sick prior to hospital admission was 1 (IQR: 1 to 2). Median PHCD was 1882 kcal (IQR: 1355 to 3650). Median number of days NPO while in-hospital was 3 (IQR: 2 to 5). Median in-hospital caloric deficit was 4268 kcal (IQR: 2825 to 6610). No significant association was observed between discharge disposition, complication rate, ambulatory status, 30-day readmission rate and PHCD. In-hospital caloric deficit was associated with complications after surgery (p < 0.0001). CONCLUSION: Small PHCD's in patients with SBO's, pancreatitis, or diverticulitis do not negatively affect their outcomes. Further research of patients with large PHCD's is needed to best treat surgical patients at risk for malnutrition.

Do Patients Regret Having Received Systemic Treatment for Advanced Non-Small Cell Lung Cancer: A Prospective Evaluation.

BACKGROUND: Thousands of patients annually receive treatment for advanced non-small cell lung cancer (NSCLC), but little is known about their views on the decision to receive that treatment, or regret. This trial prospectively evaluated the incidence of regret and whether baseline characteristics, patient decision-making parameters, or clinical progress early in the treatment course predicts regret. MATERIALS AND METHODS: Patients receiving systemic treatment for advanced NSCLC completed every 3-week patient reported outcome (PRO) assessment using the electronic Lung Cancer Symptom Scale (eLCSS-QL), including the 3-Item Global Index (3-IGI; assessing overall distress, activities, and quality of life [QL]). A prespecified secondary aim was to determine the frequency of regret evaluated at 3 months after starting treatment. Patients were randomized to usual care or enhanced care (which included use of the DecisionKEYS decision aid). RESULTS: Of 164 patients entered, 160 received treatment and 142 were evaluable for regret. In total, 11.5% of patients and 9% of their supporters expressed regret. Baseline characteristics did not predict regret; regret was rarely expressed by those who had a less than 20% decline or improvement in the 3-IGI PRO score after two treatment cycles. In contrast, when asked if they would make the same decision again, only 1% not having a 20% 3-IGI decline expressed regret, versus 14% with a 3-IGI decline (p = .01). CONCLUSION: The majority of patients having regret were identified early using the PRO 3-IGI of the eLCSS-QL measure. Identifying patients at risk for regret allows for interventions, including frank discussions of progress and goals early in the treatment course, which could address regret in patients and their supporters. IMPLICATIONS FOR PRACTICE: This report documents prospectively, for the first time, the incidence of treatment-related regret in patients with advanced lung cancer and outlines that risk of regret is associated with patient-determined worsening health status early in the course of treatment. Identifying patients at risk for regret early in treatment (before the third cycle of treatment) appears to be crucial. Counseling at that time should include a discussion of consideration of treatment change and the reason for this change.

Ultrasound Assessment of Gastric Emptying in Premature Infants Treated With Non-Invasive Ventilatory Support.

BACKGROUND: Nasal continuous positive airway pressure (CPAP) introduces positive pressure of air into both the trachea and stomach, which may affect gastric emptying. The rate of gastric emptying can be estimated by ultrasound (US) in neonates by two validated techniques: "antral cross-sectional area" (ACSA, two-dimensional estimate of the surface area at the gastric antrum), and "spheroid gastric volume" (spheroid, three-dimensional estimate of the stomach volume). OBJECTIVE: To compare gastric emptying rates in neonates on machine-derived nasal CPAP (MD-nCPAP, Avea and RAM cannula) with those on bubble CPAP (bCPAP, Fisher Paykel and Babi.Plus nasal prongs). METHODS: Ultrasound measurements of the amount of the milk in the stomach were performed before feeding and at 1, 2, and 3 hours after the start of feeding, using both the ACSA and spheroid methods. Rates of gastric emptying were calculated during the "early" (1-2 hours) and "late" (2-3 hours) phases after feeding. RESULTS: We recruited 32 infants (25-34 weeks gestational age, full enteral tube feedings, on nasal CPAP). Seventeen infants were treated with MD-nCPAP (median birth weight 1015 g [interquartile range (IQR): 870-1300], gestational age 28 weeks [IQR: 27-29], postnatal age 20 days [IQR: 14-28]), whereas 15 infants were treated with bCPAP (median birth weight 960 g [IQR: 855-1070], gestational age 27 weeks [IQR: 26-28], postnatal age 17 days [IQR: 15-25]). Gastric emptying rates (% emptied/min) were significantly faster in the "early" compared to the "late" phase for all infants. There were no significant differences in the rates of gastric emptying (either "early" or "late") or volumes of gastric residuals between infants receiving MD-nCPAP or bCPAP, measured by either method. Although no feeding intolerance was seen in either group, the volumes of residual gastric contents measured by both methods were higher than the volumes traditionally considered abnormal when obtained by gastric tube aspiration. CONCLUSIONS: Gastric emptying is faster during the "early" compared to the "late" phase. Gastric emptying rates are not different in infants receiving MD-nCPAP versus bCPAP. The presence of large residual gastric contents in infants who are tolerating feedings challenges the value of traditional gastric aspiration for the assessment of feeding tolerance in infants.

Integrative analysis of rare copy number variants and gene expression data in alopecia areata implicates an aetiological role for autophagy.

Alopecia areata (AA) is a highly prevalent autoimmune disease that attacks the hair follicle and leads to hair loss that can range from small patches to complete loss of scalp and body hair. Our previous linkage and genome-wide association studies (GWAS) generated strong evidence for aetiological contributions from inherited genetic variants at different population frequencies, including both rare mutations and common polymorphisms. Additionally, we conducted gene expression (GE) studies on scalp biopsies of 96 patients and controls to establish signatures of active disease. In this study, we performed an integrative analysis on these two datasets to test the hypothesis that rare CNVs in patients with AA could be leveraged to identify drivers of disease in our AA GE signatures. We analysed copy number variants (CNVs) in a case-control cohort of 673 patients with AA and 16 311 controls independent of the case-control cohort of 96 research participants used in our GE study. Using an integrative computational analysis, we identified 14 genes whose expression levels were altered by CNVs in a consistent direction of effect, corresponding to gene expression changes in lesional skin of patients. Four of these genes were affected by CNVs in three or more unrelated patients with AA, including ATG4B and SMARCA2, which are involved in autophagy and chromatin remodelling, respectively. Our findings identified new classes of genes with potential contributions to AA pathogenesis.

Performance and psychometric properties of lupus impact tracker in assessing patient-reported outcomes in pediatric lupus: Report from a pilot study.

OBJECTIVE: To evaluate the reliability, validity, feasibility and psychometric performance of the Lupus Impact Tracker (LIT) as a patient reported outcome (PRO) measure tool in pediatric systemic lupus erythematosus (pSLE). METHODS: This is a prospective, observational, pilot study where patients aged between 12 and 25 years, fulfilling the 1997 ACR classification criteria for SLE, were enrolled. Over 3 consecutive, routine, clinical visits, the patients completed the LIT alongside the Patient-Reported Outcomes Measurement Information System-Short Forms (PROMIS-SFs), Childhood Health Assessment Questionnaire (CHAQ). Rheumatologists completed the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC-ACR) Damage Index. Demographic, clinical and laboratory data were also collected. RESULTS: Of 46 patients enrolled, 38 patients completed 2 visits and 31 completed all 3 visits. Seventy-eight percent were female, 33% African American, 28% Asian, 15% Caucasian and 17% Hispanic. The mean (SD) age was 17.2 (2.7) years, with a mean (SD) disease duration of 4.6 (3.1) years. The mean (SD) SLEDAI-2K at enrollment was 3.54 (2.96). In the 38 patients who completed two or more visits, intra-class correlation coefficient and Cronbach alpha were calculated to be 0.70 and 0.91 respectively, signifying good reliability of LIT. The LIT showed positive correlation with CHAQ-Disability Index and majority of the PROMIS-SFs parameters. Construct validity was established against clinical disease activity (SLEDAI-2K). CONCLUSION: The preliminary results indicate that the LIT is a reliable and valid instrument to capture PRO in p-SLE. Prospective validation with a larger, multicenter cohort is the next step.

CXCR3 Blockade Inhibits T Cell Migration into the Skin and Prevents Development of Alopecia Areata.

Alopecia areata (AA) is an autoimmune disease of the hair follicle that results in hair loss of varying severity. Recently, we showed that IFN-γ-producing NKG2D(+)CD8(+) T cells actively infiltrate the hair follicle and are responsible for its destruction in C3H/HeJ AA mice. Our transcriptional profiling of human and mouse alopecic skin showed that the IFN pathway is the dominant signaling pathway involved in AA. We showed that IFN-inducible chemokines (CXCL9/10/11) are markedly upregulated in the skin of AA lesions, and further, that the IFN-inducible chemokine receptor, CXCR3, is upregulated on alopecic effector T cells. To demonstrate whether CXCL9/10/11 chemokines were required for development of AA, we treated mice with blocking Abs to CXCR3, which prevented the development of AA in the graft model, inhibiting the accumulation of NKG2D(+)CD8(+) T cells in the skin and cutaneous lymph nodes. These data demonstrate proof of concept that interfering with the Tc1 response in AA via blockade of IFN-inducible chemokines can prevent the onset of AA. CXCR3 blockade could be approached clinically in human AA with either biologic or small-molecule inhibition, the latter being particularly intriguing as a topical therapeutic.

Microenvironmental reprogramming by three-dimensional culture enables dermal papilla cells to induce de novo human hair-follicle growth.

De novo organ regeneration has been observed in several lower organisms, as well as rodents; however, demonstrating these regenerative properties in human cells and tissues has been challenging. In the hair follicle, rodent hair follicle-derived dermal cells can interact with local epithelia and induce de novo hair follicles in a variety of hairless recipient skin sites. However, multiple attempts to recapitulate this process in humans using human dermal papilla cells in human skin have failed, suggesting that human dermal papilla cells lose key inductive properties upon culture. Here, we performed global gene expression analysis of human dermal papilla cells in culture and discovered very rapid and profound molecular signature changes linking their transition from a 3D to a 2D environment with early loss of their hair-inducing capacity. We demonstrate that the intact dermal papilla transcriptional signature can be partially restored by growth of papilla cells in 3D spheroid cultures. This signature change translates to a partial restoration of inductive capability, and we show that human dermal papilla cells, when grown as spheroids, are capable of inducing de novo hair follicles in human skin.

SARS-CoV-2 neutralizing antibody titers in maternal blood, umbilical cord blood, and breast milk.

OBJECTIVE: We quantified neutralizing SARS-CoV-2 antibody against spike protein (nAb) levels after vaccination and SARS-CoV-2 infection in maternal serum, cord blood, and breast milk and determined whether they correlate with levels of spike protein binding antibody. STUDY DESIGN: Women (n = 100) were enrolled on admission for delivery. Previous SARS-CoV-2 infection was defined by anti-nucleocapsid antibodies. Levels of nAb and binding antibodies against spike receptor binding domain were measured in maternal blood, cord blood, and milk. RESULTS: Maternal nAb levels were higher after vaccine and infection than vaccine alone but waned rapidly. Levels of nAb in cord blood and milk correlated with maternal levels and were higher in cord blood than maternal. Spike protein binding antibody levels correlated with nAb. CONCLUSION: SARS-CoV-2 vaccination near delivery may boost antibody-mediated immunity in the peripartum period. Neutralizing antibodies are passed transplacentally and into milk. Spike protein binding antibody may be a feasible proxy for nAb.

Implementation and Evaluation of a Novel Media Education Curriculum for Pediatric Residents.

Introduction: Despite increasing awareness of media exposure to children and adolescents and the known value of media education for physicians, residency programs lack formal media education. Methods: We designed an interactive curriculum for pediatric residents to teach health effects of media as well as screening and counseling strategies. Instructional methods were based on constructivism, experiential learning, and situated learning theories. Participants independently reflected on a media viewing, then participated in two facilitator-led 1-hour workshops of two to three residents. Facilitators received speaker notes based on American Academy of Pediatrics media guidelines. Changes in knowledge, reported skills, and attitudes were assessed by pre- and posttests. Results: Twenty-one residents completed the curriculum from September 2021 through April 2022. Knowledge improved after the curriculum as the median score increased from 3 to 5 out of 6, although 4 months later it was insignificant. Reported skills in screening did not significantly change. Residents strongly agreed that media use was an important health issue, with medians of 9 or 10 out of 10 on all tests. Attitudes regarding residency preparedness and confidence in screening and counseling significantly improved from pretest medians of 6 and 6 out of 10, respectively, to posttest medians of 8 and 9 to 4-month posttest medians of 6 and 8. Discussion: A media curriculum for pediatric residents resulted in improved knowledge and attitudes. Enhanced attitudes demonstrated sustainability. All participants found the curriculum relevant and engaging and felt it should be continued.

Breast Milk Production Variability Among Mothers of Preterm Infants.

Introduction: Mothers of preterm infants are at risk for inadequate milk production. Pumping logs are often used to both encourage lactation in the first week and track its efficacy. Our objectives were to determine whether mothers of preterm infants who keep pumping logs are demographically different from those who do not and to determine whether this practice affects the amount of mother's own milk (MOM) fed to their infants. We also aimed at determining whether there is a correlation between: (1) time to first breast milk expression, (2) cumulative frequency of expression in the first week, and (3) milk volume on day 7 with subsequent milk volumes and percent of infant diet consisting of MOM. Methods: Mothers of infants born ≤32 weeks and ≤1,500 g were enrolled within 48 hours of birth and encouraged to keep a pumping log. Data were collected on maternal characteristics, patterns of milk expression, and milk volumes on days 7, 14, 21, and 28 after delivery. Infant data were collected via chart review. Results: Mothers who kept pumping logs provided their own milk for a greater percentage of their infant's feeds at the time of achieving full feeds (p = 0.017). The total number of expressions in the first week was correlated with milk volume on day 21 (p = 0.016) and the provision of a higher percentage of MOM feeds at discharge (p = 0.03). Milk volume on day 7 correlated with volumes obtained at days 14, 21, and 28 (p < 0.001). Conclusions: Pumping logs may affect the availability of MOM for preterm infants. Frequency of pumping in the first week and milk volume on day 7 may impact long-term lactation success for these women.

Obtaining the Best Possible Medication History at Hospital Admission: Description of a Pharmacy Technician-Driven Program to Identify Medication Discrepancies.

PURPOSE: Describe the process of obtaining the best possible medication history (BPMH) by Certified Pharmacy Technicians (CPhTs) on hospital admission to identify medication discrepancies. METHODS: Cross-sectional, descriptive study conducted between December 2016 and June 2017 at a quaternary center in New York, including all patients 18 years and older admitted to the medicine service through the Emergency Department (ED) and seen by a CPhT. CPhTs obtained the BPMH using a systematic approach involving a standardized interview, checking medications with secondary sources and updating the electronic health record (EHR). Medication discrepancies were identified and categorized by type and risk. Summary statistics were provided as average and standard deviation (SD) for continuous variables, and as frequencies and percentages for categorical variables. Multivariable regression was used to test for associations between patient factors and presence of a medication discrepancy. RESULTS: Of the 3,087 patient visits, the average age was 69 (SD 17.8), 54% were female (n = 1652) and 65% white (n = 2017); comorbidity score breakdown was: 0 (25%, n = 757), 1-2 (33%, n = 1023), 3-4 (23%, n = 699), > 4 (20%, n = 608). The average number of home and discharge medications were 10 (SD 6.1) and 10 (SD 5.4), respectively. The average time spent obtaining the BPMH was 30.6 minutes (SD 12.9). 69% of patients (n = 2130) had at least 1 discrepancy with an average of 4.2 (SD 4.6), of which 43% (n = 920) included high-risk medications. Having a medication discrepancy was associated with a higher number of home medications (p < 0.0001) comorbidities (p < 0.0001), and source of information (p < 0.04). CONCLUSION: Obtaining the BPMH by CPhTs on hospital admission frequently identifies medication discrepancies. Further studies are needed to evaluate the association between obtaining the BPMH and clinical outcomes.

Allergen Immunotherapy Extract Shortages and Their Effects on Clinical Care: A Work Group Report of the AAAAI Immunotherapy, Allergen Standardization, and Allergy Diagnostics Committee.

Allergen immunotherapy (AIT) is the only disease-modifying therapy indicated for treatment of allergic asthma, rhinitis, conjunctivitis, and Hymenoptera hypersensitivity. Manufacturing of the extracts used in AIT involve multistep complex processes as well as regulatory oversight. Furthermore, some source materials are vulnerable to unexpected events of nature. Given these circumstances, allergen extract supply can be disrupted with a potential to adversely impact patient care. A group of members from the American Academy of Allergy, Asthma, and Immunology (AAAAI) Immunotherapy, Allergy Standardization and Allergy Diagnostic Committee formed a workgroup to assess the frequency and effects of allergen extract shortages and associated factors. This workgroup developed a survey that was distributed to a random 20% of the AAAAI membership. In addition, the group also performed a review of the scientific literature on allergen extract supply and shortage. Based on the findings of the survey study and literature review, the workgroup reports frequency and extent of shortages, potential ways to improve communication with suppliers, and need for further guidance in patient care during times of shortage.

Lung ultrasound assessment of pulmonary edema in neonates with chronic lung disease before and after diuretic therapy.

INTRODUCTION: Bronchopulmonary dysplasia (BPD) is characterized by lung injury with varying degrees of disrupted alveolarization, vascular remodeling, inflammatory cell proliferation, and pulmonary edema. Diuretics are often used to ameliorate the symptoms or progression of BPD. Our primary objective was to use lung ultrasound (LUS) to determine if diuretics decrease pulmonary edema in infants with BPD. The secondary objective was to assess changes in respiratory support during the first week after initiation of diuretics. METHODS: Premature infants requiring noninvasive respiratory support and starting diuretic therapy for evolving BPD were compared with a similar group of infants not receiving diuretics (control). For the diuretic group, LUS exams were performed before and on Days 1, 3, and 6 after initiation of treatment. For the control group, LUS was performed at equivalent time points. A composite pulmonary edema severity (PES) score of 0-5 was calculated based on the total number of B-lines in six scanned areas. Respiratory support parameters (FiO2 , nasal cannula flow, or CPAP) were also recorded. RESULTS: Infants in the diuretic (n = 28) and control (n = 23) groups were recruited at median corrected gestational ages of 34.2 (33.3-35.9) and 34.0 (33.4-36.3) weeks, respectively (p = 0.82). PES scores, FiO2 , and respiratory flow support decreased significantly from Days 0 to 6 (p < 0.0001, p = 0.001, and p = 0.01, respectively) in the diuretic group, but not in the control group. CONCLUSION: Diuretic use is associated with decreased pulmonary edema and improved oxygenation in infants with BPD during the first week of treatment.

Patients Diagnosed with Multisystem Inflammatory Syndrome in Children Have Persistent Neurologic, Sleep, and Psychiatric Symptoms After Hospitalization.

Background: Acute neurological complications from COVID-19 have been reported in both pediatric and adult populations. Chronic symptoms after recovery have been reported in adults and can include neuropsychiatric and sleep symptoms. Persistent symptoms in children with the multisystem inflammatory syndrome in children (MIS-C) have not been studied. Methods: We conducted a single-center retrospective chart review and cross-sectional survey of patients diagnosed with MIS-C. Patients and parents were surveyed on symptoms before the COVID-19 pandemic, upon admission, and 23 weeks (interquartile range 20-26 weeks) after discharge. Age and gender-matched patients requiring intensive care unit (ICU) care for status asthmaticus were surveyed as a control group. Results: In this cohort of 47 patients, 77% reported neurological, 60% psychiatric, and 77% sleep symptoms during hospitalization. Prior to hospitalization, 15% reported neurological, 0% psychiatric, and 7% sleep symptoms. Eighteen (50%) of the 36 patients who had neurological symptoms during hospitalization continued to have symptoms on follow-up (odds ratio [OR] = ∞, p = .003]). Similarly, 16 (57%) of 28 patients with psychiatric symptoms reported persistence at follow-up (OR = 5.00; p = .02). Fifteen (42%) of the 18 patients reporting sleep disturbance during hospitalization had persistence on follow-up (OR = 1.9; p = .49). The aggregate of neurological, psychiatric, and sleep symptoms during admission and at follow-up was significantly higher for MIS-C patients requiring ICU care when compared to the control group (p = .01). Conclusions: In this cohort of patients with MIS-C, a majority of patients reported new-onset neuropsychiatric and sleep symptoms. Almost half of these patients had persistent symptoms on a follow-up survey.

Association of race/ethnicity with mortality in patients hospitalized with COVID-19.

OBJECTIVE: To evaluate racial and ethnic differences in mortality among patients hospitalized with coronavirus disease 2019 (COVID-19) after adjusting for baseline characteristics and comorbidities. METHODS: This retrospective cohort study at 13 acute care facilities in the New York City metropolitan area included sequentially hospitalized patients between March 1, 2020, and April 27, 2020. Last day of follow up was July 31, 2020. Patient demographic information, including race/ethnicity and comorbidities, were collected. The primary outcome was in-hospital mortality. RESULTS: A total of 10 869 patients were included in the study (median age, 65 years [interquartile range (IQR) 54-77; range, 18-107 years]; 40.5% female). In adjusted time-to-event analysis, increased age, male sex, insurance type (Medicare and Self-Pay), unknown smoking status, and a higher score on the Charlson Comorbidity Index were significantly associated with higher in-hospital mortality. Adjusted risk of hospital mortality for Black, Asian, Hispanic, multiracial/other, and unknown race/ethnicity patients were similar to risk for White patients. CONCLUSIONS: In a large diverse cohort of patients hospitalized with COVID-19, patients from racial/ethnic minorities experienced similar mortality risk as White patients.
