RESUMO

OBJECTIVE: To evaluate the proximal effects of hypertensive disorders of pregnancy (HDP) on a validated measure of brain abnormalities in infants born at ≤32 weeks' gestational age (GA) using magnetic resonance imaging at term-equivalent age. STUDY DESIGN: In a multisite prospective cohort study, 395 infants born at ≤32 weeks' GA, underwent 3T magnetic resonance imaging scan between 39 and 44 weeks' postmenstrual age. A single neuroradiologist, blinded to clinical history, evaluated the standardized Kidokoro global brain abnormality score as the primary outcome. We classified infants as HDP-exposed by maternal diagnosis of chronic hypertension, gestational hypertension, pre-eclampsia, or eclampsia. Linear regression analysis identified the independent effects of HDP on infant brain abnormalities, adjusting for histologic chorioamnionitis, maternal smoking, antenatal steroids, magnesium sulfate, and infant sex. Mediation analyses quantified the indirect effect of HDP mediated via impaired intrauterine growth and prematurity and remaining direct effects on brain abnormalities. RESULTS: A total of 170/395 infants (43%) were HDP-exposed. Adjusted multivariable analyses revealed HDP-exposed infants had 27% (95% CI 5%-53%) higher brain abnormality scores than those without HDP exposure (P = .02), primarily driven by increased white matter injury/abnormality scores (P = .01). Mediation analyses showed HDP-induced impaired intrauterine growth significantly (P = .02) contributed to brain abnormality scores (22% of the total effect). CONCLUSIONS: Maternal hypertension independently increased the risk for early brain injury and/or maturational delays in infants born at ≤32 weeks' GA with an indirect effect of 22% resulting from impaired intrauterine growth. Enhanced prevention/treatment of maternal hypertension may mitigate the risk of infant brain abnormalities and potential neurodevelopmental impairments.

RESUMO

OBJECTIVE: To evaluate whether a higher proportion of enteral vs parenteral protein ratio (E:P ratio) in the first 28 days after birth is associated with increased brain volume and somatic growth in very low birth weight (VLBW; birth weight <1500 g) infants. STUDY DESIGN: This was a retrospective analysis of a subcohort of VLBW infants (n = 256, gestational age mean 28.07 [SD 2.17] weeks, birth weight 1038.80 [SD 262.95] grams) from the Cincinnati Infant Neurodevelopment Early Prediction Study, a regional prospective study of infants born at ≤32 weeks' gestation. Brain magnetic resonance imaging was obtained at term-equivalent age. Macronutrient intake and growth metrics for the first 28 days were collected retrospectively. The primary outcome was total brain tissue volume. The relationships between E:P ratio, total and regional brain tissue volumes, and somatic growth were analyzed by multivariable linear regression models; composite variables were used to adjust for potential confounders including pregnancy risk factors and initial severity of illness. RESULTS: Higher E:P ratio was associated with increased total brain tissue volume but was not associated with change in head circumference z score. In secondary analyses, higher E:P ratio was associated with increased weight velocity. There were no significant associations between E:P ratio and change in weight or length z scores or regional brain volumes. CONCLUSIONS: Higher E:P ratio in the first 28 days was positively associated with total brain volume and weight gain. Promoting the provision of enteral over parenteral protein may improve brain and somatic growth in VLBW infants.

RESUMO

BACKGROUND: Acute kidney injury (AKI) and fluid overload (FO) are associated with poor outcomes in children receiving extracorporeal membrane oxygenation (ECMO). Our objective is to evaluate the impact of AKI and FO on pediatric patients receiving ECMO for cardiac pathology. METHODS: We performed a secondary analysis of the six-center Kidney Interventions During Extracorporeal Membrane Oxygenation (KIDMO) database, including only children who underwent ECMO for cardiac pathology. AKI was defined using Kidney Disease: Improving Global Outcomes (KDIGO) creatinine criteria. FO was defined as < 10% (FO-) vs. ≥ 10% (FO +) and was evaluated at ECMO initiation, peak during ECMO, and ECMO discontinuation. Primary outcomes were mortality and length of stay (LOS). RESULTS: Data from 191 patients were included. Non-survivors (56%) were more likely to be FO + than survivors at peak ECMO fluid status and ECMO discontinuation. There was a significant interaction between AKI and FO. In the presence of AKI, the adjusted odds of mortality for FO + was 4.79 times greater than FO- (95% CI: 1.52-15.12, p = 0.01). In the presence of FO + , the adjusted odds of mortality for AKI + was 2.7 times higher than AKI- [95%CI: 1.10-6.60; p = 0.03]. Peak FO + was associated with a 55% adjusted relative increase in LOS [95%CI: 1.07-2.26, p = 0.02]. CONCLUSIONS: The association of peak FO + with mortality is present only in the presence of AKI + . Similarly, AKI + is associated with mortality only in the presence of peak FO + . FO + was associated with LOS. Studies targeting fluid management have the potential to improve LOS and mortality outcomes. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMO

BACKGROUND: Prenatal alcohol exposure alters brain development, affecting cognitive, motor, and emotional domains, and potentially leading to greater alcohol intake during adolescence. The present study investigated whether early alcohol exposure modifies vulnerability to behavioral alterations associated with adolescent alcohol exposure in a rodent model. METHODS: Sprague-Dawley rats received ethanol or sham intubations during two developmental periods: (1) the third trimester equivalent of brain development in humans (postnatal days [PD] 4-9) and (2) adolescence (PD 28-42). Both exposures resulted in blood alcohol concentrations around 200 mg/dl. Subjects were tested in the open field (PD 45-48) and on hippocampal and prefrontal cortical (PFC) dependent tasks: the Morris water maze (PD 52-58) and trace fear conditioning (PD 63-64). RESULTS: Neonatal alcohol exposure reduced forebrain and cerebellar weight, increased open-field activity, and slowed acquisition of trace fear conditioning. Adolescent alcohol exposure did not disrupt learning or significantly induce gross brain pathology, suggesting that 200 mg/dl/day of ethanol disrupts cognitive development during the 3rd trimester equivalent, but not during adolescence. Interestingly, females exposed to alcohol only during adolescence exhibited an increased conditioned fear response and more rapid habituation of locomotor activity in the open field, suggesting alterations in emotional responding. Moreover, subjects exposed to a combination of neonatal and adolescent alcohol exposure spent significantly more time in the center of the open field chamber than other groups. Similarly, males exposed to the combination exhibited less thigmotaxis in the Morris water maze. CONCLUSIONS: These results indicate that combined exposure to alcohol during these two critical periods reduces anxiety-related behaviors and/or increases risk taking in a sex-dependent manner, suggesting that prenatal alcohol exposure may affect risk for emotional consequences of adolescent alcohol exposure.

RESUMO

BACKGROUND: Heart failure (HF) management can be improved by involving framily (family and friends) who provide valuable support. Less is known about how dyadic interactions or interactions between dyads and their extended care networks positively impact life with HF. OBJECTIVES: This study aimed to understand the positive behavioral, cognitive, and social factors through which patient-framily dyads manage health together. METHODS: Heart failure patient-framily dyads were recruited through Stanford heart failure clinics. Participants completed a 45-minute semistructured interview that elicited their experiences with managing HF. Interviews were audio recorded, transcribed for analysis, and independently coded by 2 team members using thematic analyses. RESULTS: Seventeen dyads (n = 34) participated in the study; 47% of patients and 78% of framily were women. Mean (SD) age of patients was 66 (14) years, and mean (SD) age of framily caregivers was 59 (12.3) years. Three themes showcased the positive contributions of dyadic HF management: (1) management of HF was perceived as successful when individuals in a dyad both received support from a shared care network; (2) when strength of the interpersonal relationship and love were the main motivators for care, dyads reported a positive outlook on quality of life with HF; and (3) the framily caregivers' own health conditions affected the dyadic relationship and perceived success with HF management. CONCLUSIONS: Social support by an external network and mutual support within a patient-framily dyad both create an environment of optimism and effective coping, making successful HF management possible. A dyad's success with these factors may result in better condition management and perceived quality of life.

RESUMO

Neutrophils are vital to both the inflammatory cascade and tissue repair after an injury. Neutrophil heterogeneity is well established but there is less evidence for significant, different functional roles for neutrophil subsets. OLFM4 (Olfactomedin-4) is expressed by a subset of neutrophils, and high expression of OLFM4 is associated with worse outcomes in patients with sepsis and acute respiratory distress syndrome. We hypothesized that an increased number of OLFM4+ neutrophils would occur in trauma patients with worse clinical outcomes. To test this, we prospectively enrolled patients who suffered a blunt traumatic injury. Blood was collected at the time of admission, Day 3, and Day 7 and analyzed for the percentage of neutrophils expressing OLFM4. We found that a subset of patients who suffered blunt traumatic injury upregulated their percentage of OLFM4+ neutrophils. Those who upregulated their OLFM4 had an increased length of stay, days in the ICU, and ventilator days. A majority of these patients also suffered from hemorrhagic shock. To establish a potential role for OLFM4+ neutrophils, we used a murine model of hemorrhagic shock because mice also express OLFM4 in a subset of neutrophils. These studies demonstrated that wild type mice had higher concentrations of cytokines in the plasma and myeloperoxidase in the lungs compared with OLFM4-null mice. In addition, we used an anti-OLFM4 antibody, which when given to wild type mice led to the reduction of myeloperoxidase in the lungs of mice. These findings suggest that OLFM4+ neutrophils are a unique subset of neutrophils that affect the inflammatory response after tissue injury.

RESUMO

BACKGROUND: Screen-based media use is prevalent in children and is associated with health risks. American Academy of Pediatrics (AAP) recommendations involve access to screens, frequency, content, and co-viewing. The aim of this study was to test the ScreenQ, a composite measure of screen-based media use. METHODS: ScreenQ is a 15-item parent report measure reflecting AAP recommendations. Range is 0-26, higher scores reflecting greater non-adherence. With no "gold standard" available, four validated measures of skills and parenting practices cited as influenced by overuse were applied as the external criteria, including expressive language, speed of processing, emergent literacy, and cognitive stimulation at home. Psychometric analyses involved Rasch methods and Spearman's ρ correlations. RESULTS: Sixty-nine families were administered ScreenQ. Child age ranged from 36 to 63 months old (52 ± 8; 35 girls). Mean ScreenQ score was 9.6 (±5.0; 1-22). Psychometric properties were strong (rCo-α = 0.74). ScreenQ scores were negatively correlated with CTOPP-2 (Comprehensive Test of Phonological Processing, Second Edition) (rρ = -0.57), EVT-2 (Expressive Vocabulary Test, Second Edition) (rρ = -0.45), GRTR (Get Ready to Read!) (rρ = -0.30) and StimQ-P (rρ = -0.42) scores (all p ≤ 0.01). CONCLUSIONS: ScreenQ shows potential as a composite measure of screen-based media use in young children in the context of AAP recommendations. ScreenQ scores were correlated with lower executive, language and literacy skills, and less stimulating home cognitive environment.

RESUMO

OBJECTIVE: The aim of this study was to characterize continuous renal replacement therapy (CRRT) utilization on extracorporeal membrane oxygenation (ECMO) and to determine the association of both fluid overload (FO) at CRRT initiation and fluid removal during CRRT with mortality in a large multicenter cohort. METHODS: Retrospective chart review of all children < 18 years of age concurrently treated with ECMO and CRRT from January 1, 2007, to December 31, 2011, at six tertiary care children's hospital. Children treated with hemodialysis or peritoneal dialysis were excluded from the FO analysis. MEASUREMENTS AND MAIN RESULTS: A total of 756 of the 1009 children supported with ECMO during the study period had complete FO data. Of these, 357 (47.2%) received either CRRT or were treated with an in-line filter and thus entered into the final analysis. Survival to ECMO decannulation was 66.4% and survival to hospital discharge was 44.3%. CRRT initiation occurred at median of 1 day (IQR 0, 2) after ECMO initiation. Median FO at CRRT initiation was 20.1% (IQR 5, 40) and was significantly lower in ECMO survivors vs. non-survivors (15.3% vs. 30.5% p = 0.005) and in hospital survivors vs. non-survivors (13.5% vs. 25.9%, p = 0.004). Median FO at CRRT discontinuation was significantly lower in ECMO survivors (23% vs. 37.6% p = 0.002) and hospital survivors vs. non-survivors (22.6% vs. 36.1%, p = 0.002). In ECMO survivors, after adjusting for pH at CRRT initiation, non-renal complications, ECMO mode, support type, center, patient age and AKI, FO at CRRT initiation (p = 0.01), and FO at CRRT discontinuation (p = 0.0002) were independently associated with duration of ECMO. In a similar multivariable analysis, FO at CRRT initiation (adjusted adds ratio [aOR] 1.09, 95% CI 1.00-1.18, p = 0.045) and at CRRT discontinuation (aOR 1.11, 95% CI 1.03-1.19, p = 0.01) were independently associated with hospital mortality. CONCLUSIONS: In a multicenter pediatric ECMO cohort, this study demonstrates that severe FO was very common at CRRT initiation. We found an independent association between the degree of FO at CRRT initiation with adverse outcomes including mortality and increased duration of ECMO support. The results suggest that intervening prior to the development of significant FO may be a clinical therapeutic target and warrants further evaluation.

RESUMO

OBJECTIVE: To determine whether exposure to an immersive virtual reality curriculum on pediatric respiratory distress improves medical students' recognition of impending respiratory failure. DESIGN: Randomized, controlled, prospective study conducted from July 2017 to June 2018. Evaluators blinded to student groupings. SETTING: Academic, free-standing children's hospital. PARTICIPANTS: All third-year medical students (n = 168) were eligible. The standard curriculum was delivered to all students during their pediatric rotation with optional inclusion of research data per Institutional Review Board review. A randomized selection of students was exposed to the virtual reality curriculum. INTERVENTION: All students received standard training on respiratory distress through didactics and high-fidelity mannequin simulation. Intervention students underwent an additional 30-minute immersive virtual reality curriculum, experienced through an OculusRift headset, with three simulations of an infant with 1) no distress, 2) respiratory distress, and 3) impending respiratory failure. MEASUREMENTS AND MAIN RESULTS: The impact of the virtual reality curriculum on recognition/interpretation of key examination findings, assignment of an appropriate respiratory status assessment, and recognition of the need for escalation of care for patients in impending respiratory failure was assessed via a free response clinical assessment of video vignettes at the end of the pediatric rotation. Responses were scored on standardized rubrics by physician experts. All eligible students participated (78 intervention and 90 control). Significant differences between intervention and control were demonstrated for consideration/interpretation of mental status (p < 0.01), assignment of the appropriate respiratory status assessment (p < 0.01), and recognition of a need for escalation of care (p = 0.0004). CONCLUSIONS: Exposure to an immersive virtual reality curriculum led to improvement in objective competence at the assessment of respiratory distress and recognition of the need for escalation of care for patients with signs of impending respiratory failure. This study represents a novel application of immersive virtual reality and suggests that it may be effective for clinical assessment training.

RESUMO

Neutrophil-lymphocyte ratio has been associated with clinical outcomes in several groups of cardiac patients, including patients with coronary artery disease, cardiac failure, and cardiac transplant recipients. We hypothesised that pre- and/or post-operative haematological cell counts are associated with clinical outcomes in children undergoing cardiac surgery for CHD. We performed a post hoc analysis of data collected as part of a prospective observational cohort study (n = 83, data available n = 47) of children evaluated for glucocorticoid receptor levels after cardiac surgery (July 2015-January 2016). The association of neutrophil-lymphocyte ratio with low cardiac output syndrome, time to inotrope free, and vasoactive-inotropic score was examined using proportional odds analysis, cox regression, and linear regression models, respectively. A majority (80%) of patients were infants (median/interquartile range 4.1/0.2-7.6 months) with conotruncal (36%) and left-sided obstructed lesions (28%). Two patients required mechanical circulatory support and three died. Higher pre-operative neutrophil-lymphocyte ratio was associated with higher cumulative odds of severe/moderate versus mild low cardiac output on post-operative day 1 (odds ratio 2.86; 95% confidence interval 1.18-6.93; p = 0.02). Pre-operative neutrophil-lymphocyte ratio was not significantly associated with time to inotrope free or vasoactive-inotrope score. Post-operative neutrophil-lymphocyte ratio was also not associated with outcomes. In children after congenital heart surgery, higher pre-operative neutrophil-lymphocyte ratio was associated with a higher chance of low cardiac output in the early post-operative period. Pre-operative neutrophil-lymphocyte ratio maybe a useful prognostic marker in children undergoing congenital heart surgery.

RESUMO

OBJECTIVE: To assess the utility of gastrointestinal (GI) diagnostic studies in the evaluation of patients with orthostatic intolerance. STUDY DESIGN: Medical records of 103 consecutive children/young adults with orthostatic intolerance and gastrointestinal symptoms were reviewed. All patients had undergone antroduodenal manometry in conjunction with the tilt table test, autonomic testing, and upper gastrointestinal endoscopy (EGD). A gastric emptying study (GES) was performed in 81 patients. RESULTS: The median age of the cohort was 17 years (IQR, 15-19) with a female predominance (females:males, 3:1). As expected, the tilt table test was abnormal in all patients. Antroduodenal manometry was abnormal in 83 of 103 patients (81%), showing neurogenic intestinal dysmotility in 50%, rumination in 20%, and visceral hyperalgesia in 10%. The GES results were abnormal in 23 of 81 patients (28.4%), mostly (21 of 23) with delayed GES. None of the tilt table test or autonomic results were predictive of abnormal antroduodenal manometry or GES. Analysis of EGD biopsy samples revealed nonspecific esophagitis and/or gastritis in 16 of 103 patients (15%). CONCLUSIONS: Antroduodenal manometry with the tilt table test were the most insightful investigations in adolescents and young adults with orthostatic intolerance and gastrointestinal symptoms. GES and EGD provided limited information. Gastrointestinal symptoms were related more to functional rather than mucosal or organic etiologies, suggesting a limited role of endoscopy alone in evaluating patients with orthostatic intolerance presenting with gastrointestinal symptoms.

RESUMO

BackgroundThe growth trajectories of common measurements, including estimated fetal weight (EFW), head circumference (HC), and abdominal circumference (AC), in fetuses with congenital heart disease (CHD) have not been described for different cardiac lesions. We hypothesized that (i) fetuses with CHD have differential growth in utero, and (ii) different categories of CHD demonstrate different in utero growth curves.MethodsWe performed a retrospective observational cohort study of pregnancies with known fetal CHD seen from January 2000 to June 2013. For analysis, the infants were divided into single ventricle (SV), biventricular conotruncal, d-transposition of great arteries (d-TGA), biventricular septal defects (SD; including atrial, ventricular, and atrioventricular SD), and all others (Other).ResultsA total of 194 newborns met inclusion criteria. There was significant differential growth of EFW in all CHD types, except d-TGA, starting with low z-scores before 25 weeks gestation, improving toward normal around 30-32 weeks gestation, and then again differential growth with advancing gestation. SV and SD groups had significant differential growth of HC starting early in gestation and linearly progressing negative z-scores with advancing gestation.ConclusionWe observed differences in the fetal growth curves throughout gestation for the major categories of CHD, including significant differential growth in even "simple" CHD, such as SD.

RESUMO

OBJECTIVES: Postoperative administration of corticosteroids is common practice for managing catecholamine refractory low cardiac output syndrome. Since corticosteroid activity is dependent on the glucocorticoid receptor, we sought to characterize glucocorticoid receptor levels in children undergoing cardiac surgery and examined the association between glucocorticoid receptor levels and cardiovascular dysfunction. DESIGN: Prospective observational cohort study. SETTING: Large, tertiary pediatric cardiac center. SUBJECTS: Children undergoing corrective or palliative cardiac surgery. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A prospective observational cohort study was conducted in 83 children with congenital heart disease. Total glucocorticoid receptor levels were measured in the peripheral WBCs using flow cytometry. In addition, blood samples were collected for total cortisol levels. The primary outcome studied was the time to being inotrope free. An increase in glucocorticoid receptor level from postoperative day 1 to postoperative day 3 was associated with a longer time to being inotrope free (hazard ratio, 0.49 [0.29-0.81]; p = 0.01) in the univariate analysis. This association remained significant after adjusting for age, weight, cardiopulmonary bypass time, cross clamp time, Risk Adjustment for Congenital Heart Surgery-1 score, and postoperative steroid use (hazard ratio, 0.53 [0.29-0.99]; p = 0.05). Postoperative day 3 glucocorticoid receptor level showed a trend to have longer time to being inotrope free (hazard ratio, 0.66 [0.42-1.02]; p = 0.0.06). The cortisol levels minimally increased during the study duration and did not correlate with glucocorticoid receptor levels. CONCLUSIONS: Increasing glucocorticoid receptor levels in peripheral WBCs of children undergoing cardiac surgery are associated with a longer time to being inotrope free. Cortisol levels minimally increased during the study duration. These results suggest that exposure to high-dose perioperative corticosteroids may suppress the hypothalamic-pituitary-adrenal axis leading to increase in glucocorticoid receptor levels in response to a low cortisol environment. Further studies are required to better delineate the interplay between glucocorticoid receptor levels, cortisol levels, corticosteroid exposure, and postoperative inotropic requirements.

RESUMO

The aim of the study is to determine the utility of echocardiography in the assessment of diastolic function in children and young adults with restrictive cardiomyopathy (RCM). RCM is a rare disease with high mortality requiring frequent surveillance. Accurate, noninvasive echocardiographic measures of diastolic function may reduce the need for invasive catheterization. Single-center, prospective, observational study of pediatric and young adult RCM patients undergoing assessment of diastolic parameters by simultaneous transthoracic echocardiogram (TTE) and invasive catheterization. Twenty-one studies in 15 subjects [median (IQR) = 13.8 years (7.0-19.2), 60% female] were acquired with median left ventricular end-diastolic pressure (LVEDP) 21 (IQR 18-25) mmHg. TTE parameters of diastolic function, including pulmonary vein A wave duration (r s  = 0.79) and indexed left atrial volume (r s  = 0.49), demonstrated significant positive correlation, while mitral valve A (r s  = -0.44), lateral e' (r s  = -0.61) and lateral a' (r s  = -0.61) velocities showed significant negative correlation with LVEDP. Lateral a' velocity (≤0.042 m/s) and pulmonary vein A wave duration (≥156 m/s) both had sensitivity and specificity ≥80% for LVEDP ≥ 20 mmHg. In pediatric and young adult patients with RCM, lateral a' velocity and pulmonary vein A wave duration predicted elevated LVEDP with high sensitivity and specificity; however, due to technical limitations the latter was reliably measured in 12/21 patients. These noninvasive parameters may have utility in identifying patients that require further assessment with invasive testing. These findings require validation in a multicenter prospective cohort prior to widespread clinical implementation.

RESUMO

BACKGROUND: Timely diagnosis of invasive fungal infections (IFI) in renal transplant (RT) patients on immunosuppression is often difficult, jeopardizing their life and graft. We reported IFI and their causative fungal agents in post-RT patients. MATERIALS AND METHODS: This was a retrospective 6-year clinical study carried out from 2010 to 2015 on 1900 RT patients. Clinical data included patient-donor demographics, time to onset of infection, risk factors and graft function in terms of serum creatinine (SCr). To identify IFI, we examined bronchoalveolar lavage (BAL), blood, tissue, and wound swab samples by conventional mycological methods. RESULTS: IFI were diagnosed in 30 (1.56%) patients on triple immunosuppression, mainly males (n = 25) with mean age of 36.57 ± 11.9 years at 13.12 ± 18.35 months post-RT. Aspergillus species was identified in 11 BAL, one tissue, and one wound specimen each, 30.76% of these were fatal and 15.38% caused graft loss; Candida albicans was in nine BAL, four blood, two wound swab, and one tissue specimens, 25% of these were fatal and 25% had graft loss and one mucor in BAL which was fatal. Seven patients were diabetic, 10 had superadded cytomegalovirus infection, and 15 were anti-rejected. CONCLUSION: IFI are associated with increased morbidity and mortality in RT patients. Triple immunosuppression, broad spectrum antibiotics for ≥ two weeks, diabetes and superadded infection are added risks for these patients. Prevention, early diagnosis, and appropriate management are necessary to improve their prognosis.

RESUMO

BACKGROUND: Nutrition is an important factor that affects brain development. Nutritional deficiencies can exacerbate alcohol's damaging effects. Conversely, nutritional supplementation can serve a protective role against alcohol damage and may prove to be a worthwhile intervention strategy. This study investigated dietary intake in school-aged children with heavy prenatal alcohol exposure to understand their nutritional status, compared to a national sample of typically developing children and Dietary Reference Intakes. METHODS: Dietary intake data were collected from children with confirmed histories of heavy prenatal alcohol exposure (5 to 10 years, n = 55) using the Automated Self-Administered 24-Hour Dietary Recall (ASA24). Observed nutrient levels were compared to the Dietary Reference Intakes to evaluate adequacy of nutrient intake as well as to national averages for same-aged children (What We Eat in America, NHANES 2007-2008). RESULTS: Alcohol-exposed children exhibited poorer nutritional status compared to the typically developing NHANES sample, consuming lower levels of protein, omega-3 fatty acids, magnesium, potassium, zinc, vitamins C and K, niacin, and choline. Moreover, their diets did not meet Recommended Dietary Allowance or Adequate Intake for dietary fiber, potassium, vitamins E and K, omega-3 fatty acids, and choline. CONCLUSIONS: The present findings are consistent with prior studies investigating nutritional intake in preschoolers with FASD, indicating that these children are vulnerable to nutritional inadequacies. Moreover, data suggest a specific profile of dietary intake in this population. As several nutrients are important for cognitive development, targeted interventions in clinical populations might be effective in boosting outcomes. Thus, further clinical investigation into the role of nutrition in improving cognitive outcomes is warranted.

RESUMO

Adrenal ganglioneuromas in young adults are rare and ill-understood. We report an incidentally detected adrenal gland tumor diagnosed as ganglioneuroma (mature type) in 33 years old man who presented with vomiting and epigastric pain for 2 months. Histopathology examination revealed a well-encapsulated benign tumor of mature ganglion cells and Schwann-like cells arranged in fascicles, staining strongly with NSE and s-100 proteins, with adjacent unremarkable adrenal cortex and medulla.

RESUMO

The objective of the study was to examine the association between fish and shellfish intake and diabetes in an island population, and the design of the study was Cross-sectional. Two independent population-based field surveys were conducted in Hvar Island of the eastern Adriatic coast of Croatia in May 2007 and May 2008, with a total of 1,379 adult participants. In multivariable logistic regression models, total fish intake was positively associated with diabetes prevalence in the total population (OR(Q4 vs. Q1) = 1.64; 95% CI = 1.01-2.66; p-trend = 0.09). Oily fish intake also exhibited a positive association with diabetes prevalence in the total population (OR(Q4 vs. Q1) = 2.22; 95% CI = 1.35-3.64; p-trend = 0.01) and in analyses stratified by body mass index, males and those with a high waist circumference. The study suggests an association between oily fish intake and diabetes in the population of the Hvar Island in Croatia. Longitudinal studies incorporating measures of persistent organic pollutants and local cooking practices are warranted to identify factors in fatty fish that may influence the development or persistence of diabetes.

RESUMO

Introduction: US child firearm fatality rates have risen since 2013. Child Access Prevention (CAP) laws aimed at reducing minors' access to firearms have existed since the 1980s. However, specific requirements for safe storage of firearms, standards of negligence, and penalties for offenders vary significantly by state, yielding a heterogeneous body of CAP legislation. A few studies have investigated the relative impacts of these laws on child firearm injury rates, with sometimes conflicting results. Here, we present a rapid review of the existing literature on CAP laws and their apparent impact on firearm-related injuries among US children, to assess whether CAP laws are an effective tool for reducing child firearm injuries. Methods: We conducted a rapid review of published reports that evaluated the impact of CAP laws on pediatric firearm injuries and/or deaths in the United States. We extracted target population data and outcomes of each study. The data are presented narratively. Results: A total of 14 articles met criteria for evaluation. Taken together, these studies showed that implementation of CAP legislation was associated with reduced pediatric firearm injuries and fatalities. Moreover, longitudinal or time-series studies that examined changes in pediatric firearm injuries pre/post-CAP legislation yielded the most consistent and robust findings. Conclusion: CAP laws were found to be associated with reduced pediatric firearm injuries and deaths, with the magnitude of effect being proportional to CAP law stringency.

RESUMO

INTRODUCTION: Sepsis is a leading cause of pediatric mortality. While there has been significant effort toward improving adherence to evidence-based care, gaps remain. Immersive multiuser virtual reality (MUVR) simulation may be an approach to enhance provider clinical competency and situation awareness for sepsis. METHODS: A prospective, observational pilot of an interprofessional MUVR simulation assessing a decompensating patient from sepsis was conducted from January to June 2021. The study objective was to establish validity and acceptability evidence for the platform by assessing differences in sepsis recognition between experienced and novice participants. Interprofessional teams assessed and managed a patient together in the same VR experience with the primary outcome of time to recognition of sepsis utilizing the Situation Awareness Global Assessment Technique analyzed using a logistic regression model. Secondary outcomes were perceived clinical accuracy, relevancy to practice, and side effects experienced. RESULTS: Seventy-two simulations included 144 participants. The cumulative odds ratio of recognizing sepsis at 2 min into the simulation in comparison to later time points by experienced versus novice providers were significantly higher with a cumulative odds ratio of 3.70 (95% confidence interval: 1.15-9.07, p = .004). Participants agreed that the simulation was clinically accurate (98.6%) and will impact their practice (81.1%), with a high degree of immersion (95.7%-99.3%), and the majority of side effects were perceived as mild (70.4%-81.4%). CONCLUSIONS: Our novel MUVR simulation demonstrated significant differences in sepsis recognition between experienced and novice participants. This validity evidence along with the data on the simulation's acceptability supports expanded use in training and assessment.
