Meaningful Work, Career Fit, and Professional Well-Being of Pediatric Academicians in the United States.

OBJECTIVE: Examine associations between time spent in academic activities perceived as meaningful and professional well-being among academic pediatrics faculty. METHODS: The sample comprised 248 full-time pediatric faculty (76% female, 81% white, non-Hispanic, 41% instructor or assistant professor) across the United States who completed an online survey in November 2019. Survey items included sociodemographic and professional characteristics, professional well-being measures (Stanford Professional Fulfillment Index; Maslach Burnout Inventory; Intention to Leave Academic Medicine), perceived meaningfulness of academic activities and assigned time to those activities. We defined global career fit as total percentage time assigned to professional activities considered meaningful by individuals, and activity-specific career fit as percentage time assigned to each meaningful professional activity. RESULTS: As global career fit scores increased, professional fulfillment increased (r = 0.45, P < .001), whereas burnout (r = -0.29, P < .001) and intention to leave (r = -0.22, P < .001) decreased. Regarding activity-specific career fit, for individuals who considered patient care meaningful, as assigned time to patient care increased, professional fulfillment decreased (r = -0.14, P = .048) and burnout (r = 0.16, P = .02) and intention to leave (r = 0.26, P < .001) increased. There was no significant correlation between assigned time for teaching, research, or advocacy and professional well-being. Faculty were less likely to intend to leave academic medicine as assigned time increased for administrative or leadership activities if considered meaningful (r = -0.24, P = .01). CONCLUSIONS: Time assigned to meaningful work activities may relate to professional well-being of academic pediatrics faculty. More time assigned to patient care, despite being meaningful, was associated with poor self-reported professional well-being. Effort allocation among diverse academic activities needs to be optimized to improve faculty well-being.

ROUTE-T1D: A behavioral intervention to promote optimal continuous glucose monitor use among racially minoritized youth with type 1 diabetes: Design and development.

BACKGROUND: Type 1 diabetes management is often challenging during adolescence, and many youth with type 1 diabetes struggle with sustained and optimal continuous glucose monitor (CGM) use. Due to racial oppression and racially discriminatory policies leading to inequitable access to quality healthcare and life necessities, racially minoritized youth are significantly less likely to use CGM. METHODS: ROUTE-T1D: Research on Optimizing the Use of Technology with Education is a pilot behavioral intervention designed to promote optimal CGM use among racially minoritized youth with type 1 diabetes. Intervention strategies include problem solving CGM challenges and promoting positive caregiver-youth communication related to CGM data. RESULTS: This randomized waitlist intervention provides participants with access to three telemedicine sessions with a Certified Diabetes Care and Education Specialist. Caregiver participants are also connected with a peer-parent coach. CONCLUSION: Hypothesized findings and anticipated challenges are discussed. Future directions regarding sustaining and optimizing the use of diabetes technology among racially minoritized pediatric populations are reviewed.

Post hospital admission blood lactate measurements are associated with mortality but not neurologic morbidity in children with cerebral malaria.

BACKGROUND: In children with cerebral malaria (CM) admission blood lactate has previously guided intravenous fluid therapy and been validated as a prognostic biomarker associated with death. The usefulness of post-admission measurements of blood lactate in children with CM is less clear. The strength of association between blood lactate and neurological sequelae in CM survivors, as well as the optimal duration of post-admission measurements of blood lactate to identify children at higher risk of adverse outcomes is unknown. METHODS: A retrospective cohort study of 1674 Malawian children with CM hospitalized from 2000 to 2018 who had blood lactate measurements every 6 h for the first 24 h after admission was performed. The strength of association between admission lactate or values measured at any time point in the first 24 h post-admission and outcomes (mortality and neurological morbidity in survivors) was estimated. The duration of time after admission that lactate remained a valid prognostic biomarker was assessed. RESULTS: When lactate is analysed as a continuous variable, children with CM who have higher values at admission have a 1.05-fold higher odds (95% CI 0.99-1.11) of death compared to those with lower lactate values. Children with higher blood lactate at 6 h have 1.16-fold higher odds (95% CI 1.09-1.23) of death, compared to those with lower values. If lactate levels are dichotomized into hyperlactataemic (lactate > 5.0 mmol/L) or not, the strength of association between admission lactate and mortality increases (OR = 2.49, 95% CI 1.47-4.22). Blood lactate levels obtained after 18 h post-admission are not associated with outcomes. Similarly, the change in lactate concentrations through time during the first 24 h of hospital admission is not associated with outcomes. Blood lactate during hospitalization is not associated with adverse neurologic outcomes in CM survivors. CONCLUSIONS: In children with CM, blood lactate is associated with death but not neurologic morbidity in survivors. To comprehensively estimate prognosis, blood lactate in children with CM should be assessed at admission and for 18 h afterwards.

Loss to Hospital Follow-Up in Pediatric Cerebral Malaria Survivors: A Case-Control Study.

Children surviving central nervous system (CNS) infections are at high risk of neurological, behavioral, and cognitive sequalae. Early identification, characterization, and treatment of these sequelae may improve child and family health. In Africa, it is unclear if there are demographic or clinical factors that increase the risk of post-hospital loss to follow-up in children with CNS infections. If these factors exist, targeted educational efforts to increase rates of post-hospital retention could be focused on families at highest risk. We performed a case-control study of Malawian children with cerebral malaria, a locally common CNS infection, previously admitted to a specialized research unit in Blantyre, Malawi. Routine survivor post-hospital follow-up was scheduled for 1 month, 6 months, and 12 months. We compared demographic and clinical characteristics between 84 children who missed one or more of these post-hospital visits with 120 children who attended all visits. There were no statistically significant differences in demographic or clinical characteristics between children whose families returned for all follow-up visits and those who did not. Specifically, when comparing these groups, we found no differences in age (P = 00.646), sex (P = 0.789), duration of hospitalization (P = 0.903), distance from home to hospital (P = 0.355), type or severity of neurological sequelae (P = 0.837), guardian literacy (P = 0.057), or number of discharge medications (P = 0.464). No factors assessed in this study were associated with higher risk of loss to follow-up in Malawian child survivors of CNS infections. During hospitalization, educational efforts to increase post-hospital retention should focus on all families.

Health-related quality of life in a systematically assessed cohort of children and adults with urea cycle disorders.

PURPOSE: Individuals with urea cycle disorders (UCDs) may develop recurrent hyperammonemia, episodic encephalopathy, and neurological sequelae which can impact Health-related Quality of Life (HRQoL). To date, there have been no systematic studies of HRQoL in people with UCDs. METHODS: We reviewed HRQoL and clinical data for 190 children and 203 adults enrolled in a multicenter UCD natural history study. Physical and psychosocial HRQoL in people with UCDs were compared to HRQoL in healthy people and people with phenylketonuria (PKU) and diabetes mellitus. We assessed relationships between HRQoL, UCD diagnosis, and disease severity. Finally, we calculated sample sizes required to detect changes in these HRQoL measures. RESULTS: Individuals with UCDs demonstrated worse physical and psychosocial HRQoL than their healthy peers and peers with PKU and diabetes. In children, HRQoL scores did not differ by diagnosis or severity. In adults, individuals with decreased severity had worse psychosocial HRQoL. Finally, we show that a large number of individuals would be required in clinical trials to detect differences in HRQoL in UCDs. CONCLUSION: Individuals with UCDs have worse HRQoL compared to healthy individuals and those with PKU and diabetes. Future work should focus on the impact of liver transplantation and other clinical variables on HRQoL in UCDs.

Social support, resource utilization, and well-being: a survey of adolescent parents in Washington, DC.

BACKGROUND: Adolescent parents experience worse health and socioeconomic outcomes compared to older parents. Little is known about the factors that can lead to better health and well-being among teen-headed families. A city-wide collaborative conducted a comprehensive well-being assessment of expectant and parenting teens in Washington, DC. METHODS: An online, anonymous survey was conducted with adolescent parents in Washington, DC, using convenience sampling. The survey consisted of 66 questions adapted from validated scales of quality of life and well-being. Descriptive statistics were used to describe the data overall, by subgroups of mother and father, and by subgroups of parent age. Spearman's correlations were utilized to demonstrate associations of social supports with well-being metrics. RESULTS: A total of 107 adolescent and young adult parents from Washington, DC, completed the survey; 80% of respondents identified as mothers and 20% as fathers. Younger adolescent parents rated their physical health better compared to older adolescent and young adult parents. Adolescent parents reported accessing various governmental and community-based resources in the preceding 6 months. The most used resources were supplemental food programs, with 35% receiving Supplemental Nutrition Assistance Program benefits and 24% receiving support from the Special Supplemental Nutrition Program for Women, Infants and Children. There was no significant difference in health-related well-being metrics among those who did and did not receive resources. Having higher self-reported social support was positively correlated with higher self-rated physical health, mental health, and well-being, as well as experiencing positive emotions, and was negatively correlated with experiencing negative emotions. CONCLUSION: This snapshot of the well-being of expectant and parenting teens in Washington, DC, showed overall positive physical, mental, and emotional health. Greater social support was correlated with better outcomes in these areas. Future work will leverage the multidisciplinary collaborative to translate these findings into policies and programs that meet the needs of this population.

Temporal Trends of Blood Glucose in Children with Cerebral Malaria.

Hypoglycemia, defined as a blood glucose < 2.2 mmol/L, is associated with death in pediatric cerebral malaria (CM). The optimal duration of glucose monitoring in CM is unknown. We collected data from 1,674 hospitalized Malawian children with CM to evaluate the association between hypoglycemia and death or neurologic disability in survivors. We assessed the optimal duration of routine periodic measurements of blood glucose. Children with hypoglycemia at admission had a 2.87-fold higher odds (95% CI: 1.35-6.09) of death and, if they survived, a 3.21-fold greater odds (95% CI: 1.51-6.86) of sequelae at hospital discharge. If hypoglycemia was detected at 6 hours but not at admission, there was a 7.27-fold higher odds of death (95% CI: 1.85-8.56). The presence of newly developed hypoglycemia after admission was not independently associated with neurological sequelae in CM survivors. Among all new episodes of blood sugar below a treatment threshold of 3.0 mmol/L, 94.7% occurred within 24 hours of admission. In those with blood sugar below 3.0 mmol/L in the first 24 hours, low blood sugar persisted or recurred for up to 42 hours. Hypoglycemia at admission or 6 hours afterward is strongly associated with mortality in CM. Children with CM should have 24 hours of post-admission blood glucose measurements. If a blood glucose less than the treatment threshold of 3.0 mmol/L is not detected, routine assessments may cease. Children who have blood sugar values below the treatment threshold detected within the first 24 hours should continue to have periodic glucose measurements for 48 hours post-admission.

Clinical outcomes of children and adolescents with sickle cell disease and COVID-19 infection: A year in review at a metropolitan tertiary pediatric hospital.

Background: COVID-19 was declared a global pandemic in March 2020. Early reports were primarily in adults, and sickle cell disease (SCD) was classified as a risk factor for severe COVID-19 disease. However, there are a limited number of primarily multi-center studies reporting on the clinical course of pediatric patients with SCD and COVID-19. Methods: We conducted an observational study of all patients with SCD diagnosed with COVID-19 at our institution between March 31, 2020, and February 12, 2021. Demographic and clinical characteristics of this group were collected by retrospective chart review. Results: A total of 55 patients were studied, including 38 children and 17 adolescents. Demographics, acute COVID-19 clinical presentation, respiratory support, laboratory findings, healthcare utilization, and SCD modifying therapies were comparable between the children and adolescents. Seventy-three percent (N = 40) of all patients required emergency department care or hospitalization. While 47% (N = 26) were hospitalized, only 5% (N = 3) of all patients required intensive care unit admission. Patients frequently had concurrent vaso-occlusive pain crisis (VOC) (N = 17, 43%) and acute chest syndrome (ACS) (N = 14, 35%). Those with ACS or an oxygen requirement had significantly higher white blood cell count, lower nadir hemoglobin, and higher D-dimers, supporting a pro-inflammatory and coagulopathic picture. Non-hospitalized patients were more likely to be on hydroxyurea than hospitalized patients (79 vs. 50%, p = 0.023). Conclusion: Children and adolescent patients with SCD and acute COVID-19 often present with ACS and VOC pain requiring hospital-level care. Hydroxyurea treatment appears to be protective. We observed no mortality despite variable morbidity.

Homozygous DBF4 mutation as a cause of severe congenital neutropenia.

BACKGROUND: Severe congenital neutropenia presents with recurrent infections early in life as a result of arrested granulopoiesis. Multiple genetic defects are known to block granulocyte differentiation; however, a genetic cause remains unknown in approximately 40% of cases. OBJECTIVE: We aimed to characterize a patient with severe congenital neutropenia and syndromic features without a genetic diagnosis. METHODS: Whole exome sequencing results were validated using flow cytometry, Western blotting, coimmunoprecipitation, quantitative PCR, cell cycle and proliferation analysis of lymphocytes and fibroblasts and granulocytic differentiation of primary CD34+ and HL-60 cells. RESULTS: We identified a homozygous missense mutation in DBF4 in a patient with mild extra-uterine growth retardation, facial dysmorphism and severe congenital neutropenia. DBF4 is the regulatory subunit of the CDC7 kinase, together known as DBF4-dependent kinase (DDK), the complex essential for DNA replication initiation. The DBF4 variant demonstrated impaired ability to bind CDC7, resulting in decreased DDK-mediated phosphorylation, defective S-phase entry and progression and impaired differentiation of granulocytes associated with activation of the p53-p21 pathway. The introduction of wild-type DBF4 into patient CD34+ cells rescued the promyelocyte differentiation arrest. CONCLUSION: Hypomorphic DBF4 mutation causes autosomal-recessive severe congenital neutropenia with syndromic features.

Length of Stay and Barriers to Discharge for Technology-Dependent Children During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVE: During the coronavirus disease 2019 pandemic, technology-dependent children are at risk of encountering barriers to hospital discharge because of limits to in-home services. Transition difficulties could increase length of stay (LOS). With this study, we aim to (1) evaluate change in LOS and (2) describe barriers to hospital discharge between prepandemic and early pandemic periods for technology-dependent children. METHODS: A retrospective chart review of technology-dependent children discharged from an acute and specialty pediatric hospital within a single urban area between January 1 and May 28, 2020 was conducted. Technology dependence was defined by using a validated complex chronic condition coding system. Patients discharged prepandemic and during the pandemic were compared. Outcomes included LOS and the number and type of discharge barriers (a factor not related to a medical condition that delays discharge). Multivariate regression modeling and parametric and nonparametric analysis were used to compare cohorts. RESULTS: Prepandemic, 163 patients were discharged, and 119 were discharged during the early stages of the pandemic. The most common technology dependence was a feeding tube. The unadjusted median LOS was 7 days in both groups. After adjusting for patient-level factors, discharge during the pandemic resulted in a 32.2% longer LOS (confidence interval 2.1%-71.2%). The number of discharge barriers was high but unchanged between cohorts. Lack of a trained caregiver was more frequent during the pandemic (P = .03). CONCLUSIONS: Barriers to discharge were frequent for both cohorts. Discharge during the pandemic was associated with longer LOS. It was more difficult to identify a trained caregiver during the pandemic.

Disrupted Ca2+ homeostasis and immunodeficiency in patients with functional IP3 receptor subtype 3 defects.

Calcium signaling is essential for lymphocyte activation, with genetic disruptions of store-operated calcium (Ca2+) entry resulting in severe immunodeficiency. The inositol 1,4,5-trisphosphate receptor (IP3R), a homo- or heterotetramer of the IP3R1-3 isoforms, amplifies lymphocyte signaling by releasing Ca2+ from endoplasmic reticulum stores following antigen stimulation. Although knockout of all IP3R isoforms in mice causes immunodeficiency, the seeming redundancy of the isoforms is thought to explain the absence of variants in human immunodeficiency. In this study, we identified compound heterozygous variants of ITPR3 (a gene encoding IP3R subtype 3) in two unrelated Caucasian patients presenting with immunodeficiency. To determine whether ITPR3 variants act in a nonredundant manner and disrupt human immune responses, we characterized the Ca2+ signaling capacity, the lymphocyte response, and the clinical phenotype of these patients. We observed disrupted Ca2+ signaling in patient-derived fibroblasts and immune cells, with abnormal proliferation and activation responses following T-cell receptor stimulation. Reconstitution of IP3R3 in IP3R knockout cell lines led to the identification of variants as functional hypomorphs that showed reduced ability to discriminate between homeostatic and induced states, validating a genotype-phenotype link. These results demonstrate a functional link between defective endoplasmic reticulum Ca2+ channels and immunodeficiency and identify IP3Rs as diagnostic targets for patients with specific inborn errors of immunity. These results also extend the known cause of Ca2+-associated immunodeficiency from store-operated entry to impaired Ca2+ mobilization from the endoplasmic reticulum, revealing a broad sensitivity of lymphocytes to genetic defects in Ca2+ signaling.

Changes in HDL cholesterol, particles, and function associate with pediatric COVID-19 severity.

Background: Myriad roles for high-density lipoprotein (HDL) beyond atheroprotection include immunologic functions implicated in the severity of coronavirus disease-2019 (COVID-19) in adults. We explored whether there is an association between HDL and COVID-19 severity in youth. Methods: A pediatric cohort (N = 102), who tested positive for COVID-19 across a range of disease manifestations from mild or no symptoms, to acute severe symptoms, to the multisystem inflammatory syndrome of children (MIS-C) was identified. Clinical data were collected from the medical record and reserve plasma aliquots were assessed for lipoproteins by NMR spectroscopy and assayed for HDL functional cholesterol efflux capacity (CEC). Findings were compared by COVID-19 status and symptom severity. Lipoprotein, NMR spectroscopy and CEC data were compared with 30 outpatient COVID negative children. Results: Decreasing HDL cholesterol (HDL-c), apolipoprotein AI (ApoA-I), total, large and small HDL particles and HDL CEC showed a strong and direct linear dose-response relationship with increasing severity of COVID-19 symptoms. Youth with mild or no symptoms closely resembled the uninfected. An atypical lipoprotein that arises in the presence of severe hepatic inflammation, lipoprotein Z (LP-Z), was absent in COVID-19 negative controls but identified more often in youth with the most severe infections and the lowest HDL parameters. The relationship between HDL CEC and symptom severity and ApoA-I remained significant in a multiply adjusted model that also incorporated age, race/ethnicity, the presence of LP-Z and of GlycA, a composite biomarker reflecting multiple acute phase proteins. Conclusion: HDL parameters, especially HDL function, may help identify youth at risk of more severe consequences of COVID-19 and other novel infectious pathogens.

First STEPS: Primary Outcomes of a Randomized, Stepped-Care Behavioral Clinical Trial for Parents of Young Children With New-Onset Type 1 Diabetes.

OBJECTIVE: Despite the emotional challenges of parental adjustment to a child's type 1 diabetes diagnosis and the unique complexities of early childhood, there are few programs designed to meet the needs of parents of young children at new onset. This study evaluated First STEPS (Study of Type 1 in Early childhood and Parenting Support), a stepped-care behavioral intervention designed to support parents' psychosocial functioning and promote children's glycemic outcomes. RESEARCH DESIGN AND METHODS: Using a two-site randomized clinical trial design, parents (n = 157) of children aged 1-6 years completed baseline data within 2 months of diabetes diagnosis and were randomly assigned to intervention (n = 115) or usual care (n = 42) for 9 months. Intervention steps included: 1) peer parent coaching, with step-ups to 2) structured behavioral counseling and 3) professional consultations with a diabetes educator and psychologist, based on parent mood and child HbA1c. Participants completed follow-ups at 9 and 15 months postrandomization. Primary outcomes were parent depressive symptoms and child HbA1c. RESULTS: Depressive symptoms improved in both groups, and intervention parents had significantly lower depressive symptoms at the 9- and 15-month follow-ups compared with usual care. HbA1c decreased in both groups, but there were no between-group differences at 9 or 15 months. CONCLUSIONS: First STEPS improved parents' mood following young children's type 1 diabetes diagnosis. Results indicate likely benefits of parent coach support, supplemented by intervention intensifications, including behavioral intervention and diabetes education. This model has high potential for patient engagement. The absence of a medical intervention component may explain null findings for HbA1c; incorporating targeted behavioral support for intensive diabetes treatment may maximize intervention impact.

Resident and nurse perspectives on the use of secure text messaging systems.

BACKGROUND: As hospitals shift away from pagers and towards secure text messaging systems (STMS), limited research exists on the drawbacks of such systems. Preliminary data show that introduction of STMS can lead to a dramatic increase in interruptions, which may contribute to medical errors. OBJECTIVE: This study aimed to investigate residents' and nurses' experiences with STMS at a quaternary care children's hospital. DESIGN: This was a qualitative study with focus groups. SETTING AND PARTICIPANTS: Participants were pediatric residents and nurses at Lucile Packard Children's Hospital. INTERVENTION: Focus groups were audio recorded, transcribed verbatim, and coded by 2 independent coders. Codes were discussed until consensus was reached. MAIN OUTCOME AND MEASURES: Data was analyzed through a thematic, descriptive content analysis approach. Themes were developed alongside a framework of teamwork, patient safety, and clinician well-being. RESULTS: Three resident focus groups (n = 14) and three nurse focus groups (n = 21) were held. Six themes were identified: (1) STMS can facilitate teamwork through multiple communication modalities and technological features. (2) STMS can negatively impact teamwork by decreasing face-to-face communication and frontline decision-making. (3) STMS can promote patient safety through closed-loop communication and ready access to team members. (4) STMS can negatively impact patient safety through alarm fatigue, interruptions, and miscommunication. (5) STMS can positively impact clinician well-being through satisfaction and relationship building. (6) STMS can negatively impact clinician well-being through increased stress related to communication volume. CONCLUSION: Use of STMS in the hospital setting has many advantages as well as drawbacks. With appropriate guidelines and training designed to mitigate the drawbacks, STMS have the potential to be valuable means of communication for healthcare team members.

An educational intervention to facilitate appropriate subspecialty referrals: a study assessing resident communication skills.

BACKGROUND: Our goal was to improve pediatric residents' advanced communication skills in the setting of referral to address the entrustable professional activity of subspecialty referral identified by the American Board of Pediatrics. To accomplish this aim, we created a referral and consultation curriculum to teach and assess core communication skills in subspecialty referral involving an adolescent with syncope, an anxiety-provoking symptom that is rarely associated with serious pathology. METHODS: We utilized blended multimodal educational interventions to improve resident communication skills in referral of patients. Trainees participated in 1) an interactive online module on syncope focusing on "red-flag" symptoms that would warrant a subspecialty cardiology referral and 2) a 4-h intervention with Standardized Parents (SPs), focusing on the case-based application of communication skills. Communication skills were assessed by two pre- and post- Objective Structured Clinical Examination encounters of patients with syncope, with an SP evaluation using a 20-item checklist. Analysis was performed with Sign test and McNemar's test. Trainees provided feedback on a Critical Incident Questionnaire, which was analyzed qualitatively. RESULTS: Sixty-four residents participated. There was an overall improvement in communication skills based on SP scores (82.7 ± 10.9% to 91.7 ± 5.0%, p < 0.001), and 13/20 items demonstrated significant improvement post-intervention. Residents' improved performance enabled them to address patient/family emotions, explain referral logistics, and clarify concerns to agree on a plan. CONCLUSIONS: By participating in this curriculum, residents' communication skills improved immediately post-intervention. Further research is needed to assess if this intervention improves patient care by providing residents with enduring skills to judiciously manage the referral process.

The prostate tissue-based telomere biomarker as a prognostic tool for metastasis and death from prostate cancer after prostatectomy.

Current biomarkers are inadequate prognostic predictors in localized prostate cancer making treatment decision-making challenging. Previously, we observed that the combination of more variable telomere length among prostate cancer cells and shorter telomere length in prostate cancer-associated stromal cells - the telomere biomarker - is strongly associated with progression to metastasis and prostate cancer death after prostatectomy independent of currently used pathologic indicators. Here, we optimized our method allowing for semi-automated telomere length determination in single cells in fixed tissue, and tested the telomere biomarker in five cohort studies of men surgically treated for clinically localized disease (N = 2,255). We estimated the relative risk (RR) of progression to metastasis (N = 311) and prostate cancer death (N = 85) using models appropriate to each study's design adjusting for age, prostatectomy stage, and tumor grade, which then we meta-analyzed using inverse variance weights. Compared with men who had less variable telomere length among prostate cancer cells and longer telomere length in prostate cancer-associated stromal cells, men with the combination of more variable and shorter telomere length had 3.76 times the risk of prostate cancer death (95% confidence interval [CI] 1.37-10.3, p = 0.01) and had 2.23 times the risk of progression to metastasis (95% CI 0.99-5.02, p = 0.05). The telomere biomarker was associated with prostate cancer death in men with intermediate risk disease (grade groups 2/3: RR = 9.18, 95% CI 1.14-74.0, p = 0.037) and with PTEN protein intact tumors (RR = 6.74, 95% CI 1.46-37.6, p = 0.015). In summary, the telomere biomarker is robust and associated with poor outcome independent of current pathologic indicators in surgically treated men.

Elevated Parental Stress Is Associated With Lower Self-Efficacy in Provider Communication During a Pandemic.

BACKGROUND: Effective communication between physician and parent promotes a successful alliance with families. The association of parental stress with self-efficacy when communicating during parent-physician interactions is unknown in the context of a pandemic. OBJECTIVES: Objectives of this study include quantifying and comparing the stress experienced by parents of hospitalized children before and after onset of the COVID-19 pandemic and examining the relationship of stress with self-efficacy in parent-physician communication during interactions throughout hospitalization. METHODS: We conducted in-person surveys of parents of children aged 3 months to 17 years hospitalized at a quaternary-level children's hospital, before and after onset of COVID-19. Parents completed 2 validated tools: Parenting Stress Index (PSI-SF) and the Perceived Efficacy in Parent-Physician Interactions (PEPPI), measuring self-efficacy in communicating with physicians. Socioeconomic data were collected. Fisher exact test and t test were used to compare score proportions and means; linear regression was used to evaluate association between PSI-SF and PEPPI with confounder adjustments. RESULTS: Forty-nine parents were recruited; the majority identified as non-White and female. An inverse relationship was noted between the total stress score and parental self-efficacy, which only attained statistical significance in the post-COVID-19 cohort (P = .02, multivariate P = .044). A significant increase in the mean was observed for subscale scores of Difficult Child (P = .019) and Parent-Child Dysfunctional Interaction after COVID-19 (P = .016). CONCLUSIONS: Elevated parental stress is associated with decreased self-efficacy during parent-physician interactions and it worsened during the pandemic. Future studies should examine the effect of different communication styles on parental stress and self-efficacy during hospitalization.

Effects of Isocaloric Fructose Restriction on Ceramide Levels in Children with Obesity and Cardiometabolic Risk: Relation to Hepatic De Novo Lipogenesis and Insulin Sensitivity.

Sugar intake, particularly fructose, is implicated as a factor contributing to insulin resistance via hepatic de novo lipogenesis (DNL). A nine-day fructose reduction trial, controlling for other dietary factors and weight, in children with obesity and metabolic syndrome, decreased DNL and mitigated cardiometabolic risk (CMR) biomarkers. Ceramides are bioactive sphingolipids whose dysregulated metabolism contribute to lipotoxicity, insulin resistance, and CMR. We evaluated the effect of fructose reduction on ceramides and correlations between changes observed and changes in traditional CMR biomarkers in this cohort. Analyses were completed on data from 43 participants. Mean weight decreased (-0.9 ± 1.1 kg). The majority of total and subspecies ceramide levels also decreased significantly, including dihydroceramides, deoxyceramides and ceramide-1-phoshates. Change in each primary ceramide species correlated negatively with composite insulin sensitivity index (CISI). Change in deoxyceramides positively correlated with change in DNL. These results suggest that ceramides decrease in response to dietary fructose restriction, negatively correlate with insulin sensitivity, and may represent an intermediary link between hepatic DNL, insulin resistance, and CMR.

Multinational Analysis of Children Transfused With Pathogen Inactivated Platelets.

BACKGROUND: Pathogen inactivated (PI) platelets are a technological advancement in blood safety; however, the pediatric experience is not well characterized. We studied pediatric patients who received transfusions of PI platelets across several centers and countries to determine if transfusion reaction rates differed when compared with conventional platelets. METHODS: This is a retrospective multisite study conducted during 2 time periods. The study period started at the time each site began using PI platelets on a widespread basis, and the control period was a similar timespan before PI introduction. Suspected acute transfusion reactions were compared. RESULTS: The study included 3839 pediatric patients who were 0 to 18 years of age who received >7930 platelet transfusions, in total, across 4 centers in 3 countries between 2013 and 2019. The age distribution of patients in the study and control period was not significantly different (P = .190). There was not a difference in the percentage of patients who had any type of transfusion reaction between the time periods (1.0% and 1.1%, P = .803). There were fewer patients with mild allergic reactions in the study period compared with the control period (0.2% and 0.7% of patients with reactions, respectively, P = .018). CONCLUSIONS: Pediatric patients have the same rate of acutely suspected transfusion reactions when receiving PI or conventional platelet transfusions. Subgroup analysis found fewer mild allergic reactions in the study period, which was contemporaneous to the addition of using platelet additive solution more broadly. Future studies of PI platelets should include children to better assess transfusion efficacy and hemostatic outcomes.
