RESUMO

INTRODUCTION: Childhood obesity increased in the first year of COVID-19 with significant disparities across race, ethnicity, and socioeconomic status. Social distancing led to fewer physical activity opportunities but increased screen time and high-calorie food consumption, all co-determined by neighborhood environments. This study aimed to test the moderation effects of neighborhood socioeconomic and built environments on obesity change during COVID-19. METHODS: Using electronic health records from a large pediatric primary care network in 2018-2022, we cross-sectionally examined 163,042 well visits of 2-17-year-olds living in Philadelphia County in order to examine (1) the pandemic's effect on obesity prevalence and (2) moderation by census-tract-level neighborhood socioeconomic disadvantage, crime, food and physical activity-related environments using interrupted-time-series analysis, Poisson regression, and logistic regression. RESULTS: Weekly obesity prevalence increased by 4.9 percent points (pp) during the pandemic (January 2021-August 2022) compared to pre-pandemic (March 2018-March 2020) levels. This increase was pronounced across all age groups, racially/ethnically minoritized groups, and insurance types (ranging from 2.0 to 6.4 pp) except the Non-Hispanic-white group. The increase in obesity among children racially/ethnically minoritized groups was significantly larger in the neighborhoods with high social vulnerability (3.3 pp difference between high and low groups), and low collective efficacy (2.0 pp difference between high and low groups) after adjusting for age, sex, and insurance type. CONCLUSIONS: Racially/ethnically minoritized children experienced larger obesity increases during the pandemic, especially those in socioeconomically disadvantaged neighborhoods. However, the buffering effect of community collective efficacy on the disparities underscores the importance of environments in pediatric health.

RESUMO

OBJECTIVE: Prior evidence demonstrates that both firearm access and fighting can predict future violence and injury in adolescents. We aimed to examine associations between firearm access with fighting behavior and conflict perception in a sample of adolescents in an urban emergency department (ED) setting. METHODS: In 2023, we conducted a secondary analysis of 13,610 adolescent encounters in the ED of a U.S. children's hospital from 2013 to 2020, using a universally applied, self-administered computerized behavioral health survey. We compared patient characteristics by reported firearm access and fighting behavior using chi-squared tests. Generalized estimating equations (GEE) were used to investigate associations between 1) fighting behavior and firearm access, and 2) between fighting behavior and respondent preference to and reporting of fighting incident to law enforcement after adjusting for race and ethnicity, age, and gender. RESULTS: Approximately one-quarter of the sample reported past year fighting. Youth who reported fighting were more likely to report firearm access (AOR = 1.66, 95%CI = [1.49-1.86]). This association strengthened among youth who perceived continued conflict after a fight (AOR = 2.05, 95%CI = [1.73-2.43]). Youth who perceived continued conflict following a fight were more likely to report (AOR = 1.97, 95%CI = [1.65-2.36]) or want to report (AOR = 2.63, 95%CI = [1.81-3.81]) the fight to law enforcement. CONCLUSIONS: Those perceiving continued conflict after a fight were more likely to report access to firearms and endorse retaliation; however, they were more likely to want to report the fight to law enforcement. These findings highlight the potential for more comprehensive ED risk assessment to reduce retaliation and reinjury for adolescents reporting fighting behavior.

RESUMO

BACKGROUND: Family-centred care (FCC), while a core value of paediatric hospitals, has not been well-studied in the paediatric cardiac intensive care unit (PCICU). AIM: To describe parents' perceptions of FCC provided by nurses in the PCICU during their infant's recovery from neonatal cardiac surgery and explore associations of perceptions of FCC on parent post-traumatic stress (PTS) 4 months post-discharge. STUDY DESIGN: Data obtained from a previously conducted randomized clinical trial (RCT) on telehealth home monitoring after neonatal cardiac surgery at three free-standing paediatric hospitals were analysed from a subset of 164 parents who completed the FCC Scale at hospital discharge, which measures a parent's experience of nursing care that embodies core principles of FCC. The RCT intervention was provided after hospital discharge, having no influence on parent's perception of FCC. The intervention also had no effect on PTS. RESULTS: Perceived FCC was lowest for items 'nurses helped me feel welcomed' and 'nurses helped me feel important in my child's care'. Having 12%-19% points lower perception of FCC at hospital discharge was associated with parent experience of six or more PTS symptoms, at least moderate PTS symptom severity, or PTS disorder diagnosis at 4-month follow-up. Every 10% increase in parental perceptions of FCC was associated with less PTS symptoms (ß = -0.29, SE = 0.12; p = .02) and lower PTS symptom cluster scores of arousal (ß = -0.18, SE = 0.08; p = .02). CONCLUSIONS: Parents who perceived lower FCC during their infants' hospitalization were at increased risk for the development of PTS symptoms, more PTS symptom severity and PTS disorder diagnosis 4-months post-discharge. RELEVANCE TO CLINICAL PRACTICE: Nurses have a prominent role to support the implementation of FCC for infants with cardiac defects and their parents. FCC may positively influence overall parent mental health and well-being, reducing the trauma and distress of the PCICU experience.

RESUMO

Researchers generally agree that when upregulating and downregulating emotion, control regions in the prefrontal cortex turn up or down activity in affect-generating brain areas. However, the "affective dial hypothesis" that turning up and down emotions produces opposite effects in the same affect-generating regions is untested. We tested this hypothesis by examining the overlap between the regions activated during upregulation and those deactivated during downregulation in 54 male and 51 female humans. We found that upregulation and downregulation both recruit regulatory regions, such as the inferior frontal gyrus and dorsal anterior cingulate gyrus, but act on distinct affect-generating regions. Upregulation increased activity in regions associated with emotional experience, such as the amygdala, anterior insula, striatum, and anterior cingulate gyrus as well as in regions associated with sympathetic vascular activity, such as periventricular white matter, while downregulation decreased activity in regions receiving interoceptive input, such as the posterior insula and postcentral gyrus. Nevertheless, participants' subjective sense of emotional intensity was associated with activity in overlapping brain regions (dorsal anterior cingulate, insula, thalamus, and frontal pole) across upregulation and downregulation. These findings indicate that upregulation and downregulation rely on overlapping brain regions to control and assess emotions but target different affect-generating brain regions.SIGNIFICANCE STATEMENT Many contexts require modulating one's own emotions. Identifying the brain areas implementing these regulatory processes should advance understanding emotional disorders and designing potential interventions. The emotion regulation field has an implicit assumption we call the affective dial hypothesis: both emotion upregulation and downregulation modulate the same emotion-generating brain areas. Countering the hypothesis, our findings indicate that up- and down-modulating emotions target different brain areas. Thus, the mechanisms underlying emotion regulation might differ more than previously appreciated for upregulation versus downregulation. In addition to their theoretical importance, these findings are critical for researchers attempting to target activity in particular brain regions during an emotion regulation intervention.

RESUMO

Heart rate variability is a robust biomarker of emotional well-being, consistent with the shared brain networks regulating emotion regulation and heart rate. While high heart rate oscillatory activity clearly indicates healthy regulatory brain systems, can increasing this oscillatory activity also enhance brain function? To test this possibility, we randomly assigned 106 young adult participants to one of two 5-week interventions involving daily biofeedback that either increased heart rate oscillations (Osc+ condition) or had little effect on heart rate oscillations (Osc- condition) and examined effects on brain activity during rest and during regulating emotion. While there were no significant changes in the right amygdala-medial prefrontal cortex (MPFC) functional connectivity (our primary outcome), the Osc+ intervention increased left amygdala-MPFC functional connectivity and functional connectivity in emotion-related resting-state networks during rest. It also increased down-regulation of activity in somatosensory brain regions during an emotion regulation task. The Osc- intervention did not have these effects. In this healthy cohort, the two conditions did not differentially affect anxiety, depression, or mood. These findings indicate that modulating heart rate oscillatory activity changes emotion network coordination in the brain.

RESUMO

BACKGROUND: Various life course factors can affect susceptibility to diseases during adolescence and adulthood, and those relationships are complex. However, few studies have assessed the potential mediating factors. Therefore, we assessed the mediating effects of factors related to growth and inflammation between perinatal factors and metabolic syndrome risk during adolescence. METHODS: The study was conducted on adolescents who participated in the follow-up in the Ewha Birth and Growth Cohort. We considered the ponderal index (PI) as a perinatal factor and the continuous metabolic syndrome score (cMetS) as the outcome and confirmed the mediating effects of body mass index (BMI) trajectory pattern in childhood and inflammation levels by using the PROCESS macro for SAS. RESULTS: Although the direct effect of BMI trajectory on the relationship between PI and cMetS was not significant (0.545), the indirect effect was significant (1.044). In addition, the indirect effect was statistically significant in the pathways mediating the BMI trajectory pattern and inflammation (ß = 1.456). CONCLUSIONS: The direct and indirect effects on the relationship between PI and cMetS suggest that childhood factors related to growth may be involved in disease susceptibility. Therefore, appropriate interventions for the management of obesity during the growth phase are necessary. IMPACT: Unlike other existing studies, this study assessed multiple mediating effects by considering the BMI trajectory pattern and inflammatory indexes as mediating factors between the ponderal index and the continuous metabolic syndrome score during adolescence. We found significant indirect effects of the BMI trajectory between PI and cMetS, and also significant indirect effects in the pathways mediating the BMI trajectory and hs-CRP. The significant indirect mediating effects support that childhood factors related to growth may be involved in disease susceptibility.

RESUMO

Prior studies suggest that sex differences in emotion regulation (ER) ability contribute to sex disparities in affective disorders. In behavioral studies, females rely more on maladaptive strategies to cope with emotional distress than males. Neuroimaging studies suggest that males more efficiently regulate emotion than females by showing less prefrontal cortex activity (suggesting less effort) for similar amygdala activity (similar regulation outcome). However, physiological studies involving heart rate variability (HRV) indicated that, compared with males, females have higher resting HRV, indicative of parasympathetic dominance and better control of emotion. To help resolve these apparently inconsistent findings, we examined sex differences in how resting HRV relates to brain activity while using cognitive reappraisal, one of the adaptive strategies. Based on 51 males and 49 females, we found that females showed different levels of self-rated emotional intensity and amygdala activity for negative versus positive emotions, while males did not. Females also showed greater overall prefrontal cortex activity but similar levels of amygdala activity compared to males. Sex differences in how resting HRV related to brain activity during ER were evident only during viewing or regulating positive emotion. The results suggest that sex differences in the neural correlates of ER and resting HRV might lie in valence more than arousal modulation.

RESUMO

BACKGROUND: Acute kidney injury after pediatric cardiac surgery is a common complication with few established modifiable risk factors. We sought to characterize whether indexed oxygen delivery during cardiopulmonary bypass was associated with postoperative acute kidney injury in a large pediatric cohort. METHODS: This was a retrospective analysis of patients under 1 year old undergoing cardiac surgery with cardiopulmonary bypass between January 1, 2013, and January 1, 2020. Receiver operating characteristic curves across values ranging from 260 to 400 mL/min/m2 were used to identify the indexed oxygen delivery most significantly associated with acute kidney injury risk. RESULTS: We included 980 patients with acute kidney injury occurring in 212 (21.2%). After adjusting for covariates associated with acute kidney injury, an indexed oxygen delivery threshold of 340 mL/min/m2 predicted acute kidney injury in STAT 4 and 5 neonates (area under the curve = 0.66, 95% CI = 0.60 - 0.72, sensitivity = 56.1%, specificity = 69.4%). An indexed oxygen delivery threshold of 400 mL/min/m2 predicted acute kidney injury in STAT 1-3 infants (area under the curve = 0.65, 95% CI = 0.58 - 0.72, sensitivity = 52.6%, specificity = 74.6%). CONCLUSION: Indexed oxygen delivery during cardiopulmonary bypass is a modifiable variable independently associated with postoperative acute kidney injury in specific pediatric populations. Strategies aimed at maintaining oxygen delivery greater than 340 mL/min/m2 in complex neonates and greater than 400 mL/min/m2 in infants may reduce the occurrence of postoperative acute kidney injury in the pediatric population.

RESUMO

Previous research suggests that implicit automatic emotion regulation relies on the medial prefrontal cortex (mPFC). However, most of the human studies supporting this hypothesis have been correlational in nature. In the current study, we examine how changes in mPFC-left amygdala functional connectivity relate to emotional memory biases. In a randomized clinical trial examining the effects of heart rate variability (HRV) biofeedback on brain mechanisms of emotion regulation, we randomly assigned participants to increase or decrease heart rate oscillations while receiving biofeedback. After several weeks of daily biofeedback sessions, younger and older participants completed an emotional picture memory task involving encoding, recall, and recognition phases as an additional measure in this clinical trial. Participants assigned to increase HRV (Osc+) (n = 84) showed a relatively higher rate of false alarms for positive than negative images than participants assigned to decrease HRV (Osc-) (n = 81). Osc+ participants also recalled relatively more positive compared with negative items than Osc- participants, but this difference was not significant. However, a summary bias score reflecting positive emotional memory bias across recall and recognition was significantly higher in the Osc+ than Osc- condition. As previously reported, the Osc+ manipulation increased left amygdala-mPFC resting-state functional connectivity significantly more than the Osc- manipulation. This increased functional connectivity significantly mediated the effects of the Osc+ condition on emotional bias. These findings suggest that, by increasing mPFC coordination of emotion-related circuits, daily practice increasing heart rate oscillations can increase implicit emotion regulation.

RESUMO

Previous research suggests that higher heart rate variability (HRV) is associated with better cognitive function. However, since most previous findings on the relationship between HRV and cognitive function were correlational in nature, it is unclear whether individual differences in HRV play a causal role in cognitive performance. To investigate whether there are causal relationships, we used a simple breathing manipulation that increases HRV through a 5-week HRV biofeedback intervention and examined whether this manipulation improves cognitive performance in younger and older adults (N = 165). The 5-week HRV biofeedback intervention did not significantly improve inhibitory control, working memory and processing speed across age groups. However, improvement in the Flanker score (a measure of inhibition) was associated with the amplitude of heart rate oscillations during practice sessions in the younger and older intervention groups. Our results suggest that daily practice to increase heart rate oscillations may improve inhibitory control, but future studies using longer intervention periods are warranted to replicate the present finding.

RESUMO

PURPOSE: To explore the relationships between growth trajectory, parenting stress and parent post-traumatic stress (PTS), in infants with congenital heart disease, and the moderating role of parents' dyadic adjustment on those associations. DESIGN AND METHODS: A secondary analysis of data from the REACH Telehalth home monitoring multi-site randomized clinical trial. Parents completed the Parenting Stress Index (PSI), Post-traumatic diagnostic scale, and the Dyadic Adjustment Scale. Multivariate logistic regression models were used to examine the associations of interest. RESULTS: During 4-month follow-up after hospital discharge, parents of infants with 'Never recovered' and 'Partially recovered' growth trajectories had 2-5 times higher odds of experiencing higher stress on the Parent Domain (OR = 4.8, CI = 1.3-18.0; OR = 2.5, CI = 1.0-5.9, respectively) than those with stably grown infants. Parents of "Never recovered" infants had 4 times higher odds of PTS symptoms (OR = 3.9; CI = 1.6-9.9). Parental dyadic adjustment moderated the relationships. Parents of 'Partially recovered' infants and having low dyadic adjustment had 3-5 times higher odds of high stress on all PSI domains, while parents with high dyadic adjustment did not have increased stress due to poor infant growth. Parents of "Never recovered" infants had four times higher odds of PTS symptom, even with high dyadic adjustment. CONCLUSIONS: Infant growth trajectory over the first four months is associated with parenting stress and PTS. Quality of partner relationship moderates some of these associations. PRACTICE IMPLICATIONS: Infant growth should serve as a screening aid for identifying parents at psychological risk. Interventions targeting the quality of partner relationship may support parental coping and mitigate stress. CLINICAL TRIAL REGISTRATION: NCT01941667.

RESUMO

Previous research suggests that excessive negative self-related thought during mind wandering involves the default mode network (DMN) core subsystem and the orbitofrontal cortex (OFC). Heart rate variability (HRV) biofeedback, which involves slow paced breathing to increase HRV, is known to promote emotional well-being. However, it remains unclear whether it has positive effects on mind wandering and associated brain function. We conducted a study where young adults were randomly assigned to one of two 5-week interventions involving daily biofeedback that either increased heart rate oscillations via slow paced breathing (Osc+ condition) or had little effect on heart rate oscillations (active control or Osc- condition). The two intervention conditions did not differentially affect mind wandering and DMN core-OFC functional connectivity. However, the magnitude of participants' heart rate oscillations during daily biofeedback practice was associated with pre-to-post decreases in mind wandering and in DMN core-OFC functional connectivity. Furthermore, the reduction in the DMN core-OFC connectivity was associated with a decrease in mind wandering. Our results suggested that daily sessions involving high amplitude heart rate oscillations may help reduce negative mind wandering and associated brain function.

RESUMO

Objectives. To identify associations between patient race and annual chlamydia screening among adolescent females. Methods. We performed a retrospective cohort study of females aged 15 to 19 years in a 31-clinic pediatric primary care network in Pennsylvania and New Jersey from 2015 through 2019. Using mixed-effect logistic regressions, we estimated associations between annual chlamydia screening and patient (race/ethnicity, age, previous chlamydia screening and infection, insurance type) and clinic (size, setting) characteristics. We decomposed potential effects of clinician's implicit racial bias and screening, using covariates measuring the proportion of Black patients in each clinician's practice. Results. There were 68 935 well visits among 37 817 females, who were 28.8% Black and 25.8% Medicaid insured. The mean annual chlamydia screening rate was 11.1%. Black females had higher odds of screening (adjusted odds ratio [AOR] = 1.67; 95% confidence interval [CI] = 1.51, 1.84) than did White females. In the clinician characteristics model, individual clinicians were more likely to screen their Black versus non-Black patients (AOR = 1.88; 95% CI = 1.65, 2.15). Conclusions. Racial bias may affect screening practices and should be addressed in future interventions, given the critical need to increase population-level chlamydia screening.(Am J Public Health. 2022;112(1):135-143. https://doi.org/10.2105/AJPH.2021.306498).

RESUMO

PURPOSE: We aimed to describe the weight-for-age Z-score growth trajectory (WAZ-GT) of infants with complex congenital heart disease (cCHD) after neonatal cardiac surgery in the first 4 months of life and assess potential risk factors. METHODS: We utilized data from a previously reported trial of the REACH telehealth home monitoring (NCT01941667) program which evaluated 178 infants with cCHD from 2012 to 2017. Over the first 4 months of life, weekly infant weights were converted to WAZ. WAZ-GT classes were identified using latent class growth modeling. Multinomial logistic regression models were used to examine the associations between potential risk factors and WAZ-GT classes. RESULTS: Four distinct classes of WAZ-GT were identified: maintaining WAZ > 0, 14%; stable around WAZ = 0, 35%; partially recovered, 28%; never recovered, 23%. Compared with reference group "stable around WAZ=0," we identified clinical and sociodemographic determinants of class membership for the three remaining groups. "Maintaining WAZ > 0" had greater odds of having biventricular physiology, borderline appetite, and a parent with at least a college education. "Partially recovered" had greater odds of hospital length of stay>14 days and being a single child in the household. "Never recovered" had greater odds hospital length of stay >14 and > 30 days, tube feeding at discharge, and low appetite. CONCLUSIONS: This study described distinct classes of WAZ-GT for infants with cCHD early in infancy and identified associated determinants. PRACTICE IMPLICATIONS: Findings from this study can be used in the identification of infants at risk of poor WAZ-GT and in the design of interventions to target growth in this vulnerable patient population.

RESUMO

OBJECTIVES: To provide sex, age, and race specific reference values for ramp cycle ergometer cardiopulmonary exercise test (CPET) in children in the US. STUDY DESIGN: Retrospective review was conducted of all cardiopulmonary CPET data from our Exercise Physiology Laboratory on healthy children and adolescents (6-18 years) with body mass index between the 5th and 95th percentiles and structurally normal hearts who performed a ramp cycle ergometry stress test between 1999 and 2015. Twenty-eight exercise variables were included: peak oxygen consumption, oxygen consumption at ventilatory anaerobic threshold, peak work rate, resting and peak heart rate and blood pressure, resting pulmonary function testing, and ventilatory responses to progressive exercise using breath-by-breath gas exchange. Owing to the nonlinear association between CPET results and age, fractional polynomials were used in the mixed-effects regression models to describe the sex- and age-specific normative values with 95% CIs, after adjusting for race and body mass index. RESULTS: We analyzed data on 1829 children (average age, 13.6 ± 2.6 years; 52% male). After 12 years of age, males generally had higher peak values for aerobic capacity and work rate. There were progressive increases with age for both sexes in resting pulmonary function and ventilatory response to exercise, peak aerobic and work rate, and oxygen pulse. Notably, there was an age-related decrease in ventilatory equivalents of oxygen and carbon dioxide at the ventilatory anaerobic threshold. CONCLUSIONS: Future research using prospective, inclusive, and statistically planned cohorts with standardized laboratory approaches and confirmed interoperability should be considered as a focus for validating normative pediatric CPET values in the future.

RESUMO

OBJECTIVE: To evaluate the effect of a standardized feeding approach using a clinical nutrition pathway on weight-for-age Z score (WAZ) over hospital length of stay (HLOS) for infants with congenital heart disease (CHD). STUDY DESIGN: A 10-year retrospective cohort study examined eligible infants who underwent neonatal cardiac surgery between July 2009 and December 2018 (n = 987). Eligibility criteria included infants born at least 37 weeks of gestation and a minimum birth weight of 2 kg who underwent cardiac surgery for CHD within the first 30 days of life. Using the best linear unbiased predictions from a linear mixed effects model, WAZ change over HLOS was estimated before and after January 2013, when the standardized feeding approach was initiated. The best linear unbiased predictions model included adjustment for patient characteristics including sex, race, HLOS, and class of cardiac defect. RESULTS: The change in WAZ over HLOS was significantly higher from 2013 to 2018 than from 2009 to 2012 (ß = 0.16; SE = 0.02; P < .001), after controlling for sex, race, HLOS, and CHD category, indicating that infants experienced a decreased WAZ loss over HLOS after the standardized feeding approach was initiated. Additionally, differences were found in WAZ loss over HLOS between infants with single ventricle CHD (ß = 0.26; SE = 0.04; P < .001) and 2 ventricle CHD (ß = 0.04; SE = 0.02; P = .04). CONCLUSIONS: These data suggest that an organized, focused approach for nutrition therapy using a standardized pathway improves weight change outcomes before hospital discharge for infants with single and 2 ventricle CHD who require neonatal cardiac surgery.

RESUMO

The 22q11.2 duplication syndrome (22q11.2DupS) is characterized by phenotypic heterogeneity, from seemingly asymptomatic to severely affected patients. Our study sought to detail the cardiac phenotype associated with 22q11.2DupS, the prevalence of aortic arch anomalies and aortic root dilation in 22q11.2DupS, and to assess how frequently new congenital heart disease (CHD) is diagnosed at outpatient cardiac evaluation following genetic diagnosis. In our cohort of 85 patients, 20.0% had CHD, with a wide range of phenotypes. Sixty-eight patients had complete cardiac evaluations detailing aortic arch sidedness and branching pattern, of which 5 (7.4%) had an aortic arch anomaly, all of whom had concurrent intracardiac CHD. Of 53 patients without CHD who had complete cardiac evaluations, only 3 (5.7%) had evidence of aortic root dilation. Of 46 patients who underwent outpatient cardiac evaluation following diagnosis of 22q11.2DupS, only one (2.2%) was found to have CHD, an isolated bicuspid aortic valve without stenosis. Therefore, the CHD phenotype in 22q11.2DupS, when present, is heterogeneous. Aortic arch anomalies are uncommon, and no patient in our cohort had one in isolation. Isolated aortic root dilation is also uncommon. Finally, outpatient cardiac evaluation following genetic diagnosis without previously known CHD infrequently identified minor cardiac malformations.

RESUMO

BACKGROUND: Ultrafiltration (UF) is used for fluid removal during and after infant cardiopulmonary bypass (CPB) surgery to reduce fluid overload. Excessive UF may have the opposite of its intended effect, resulting in acute kidney injury (AKI), oliganuria, and fluid retention. METHODS: This is a single-center, retrospective review of infants treated with conventional and/or modified UF during CPB surgery. UF volume was indexed to weight. AKI was defined using serum creatinine "Kidney Disease Improving Global Outcome (KDIGO)" criteria. Fluid balance was defined according to: [Formula: see text]. Peak fluid overload was determined on postoperative day 3. Multivariable logistic regression adjusted for multiple covariates was used to explore associations with UF, AKI, and fluid overload. RESULTS: Five hundred thirty subjects < 1 year of age underwent CPB-assisted congenital heart surgery with UF. Sixty-four (12%) developed postoperative AKI. On multivariable regression, higher indexed total UF volume was associated with increased AKI risk (OR 1.11, 95% CI=1.04-1.19, p = 0.003). UF volume > 119.9 mL/kg did not reduce peak fluid overload. Subjects with AKI took longer to reach a negative fluid balance (2 vs. 3 days, p = 0.04). Those with more complex surgery were at highest AKI risk (STAT 3 [25-75 percentile: 3-4] in AKI group versus STAT 3 [25-75 percentile: 2-4] in non-AKI group, p = 0.05). AKI was reduced in subjects undergoing more complex surgery and treated with UF volume < 119.9 mL/kg. CONCLUSIONS: Judicious use of UF in more complex congenital cardiac surgery reduces the risk of AKI.

RESUMO

Aortic root dilation (ARD) has been reported in patients with 22q11.2 deletion syndrome (22q11.2DS) with and without congenital heart defects (CHDs). However, the long-term implications of isolated ARD in 22q11.2DS remain undefined. In this study, we measured aortic root size and estimated the probability of changing between normal aortic root size and ARD during follow up to understand the prevalence, longitudinal course, and clinical risk factors for ARD in patients with 22q11.2DS without intracardiac CHDs. Aortic root size was measured in 251 patients with 432 studies. Forty-one patients (16.3%) had ARD on at least one echocardiogram and the cohort sinus Z-score was increased on the last echocardiogram [mean (1.09, SD 1.24) and median (1.20, min - 1.90 and max 5.40)]. Transition probability analysis showed that 8.1% of patients developed ARD and 45.4% of patients with ARD reverted to normal at the next echocardiogram. The risk of ARD over time was significantly associated with male sex (OR 3.06, 95% CI 1.41-6.65; p = 0.004), but not with age or presence of an aortic arch anomaly. Compared to a sinus Z-score ≥ 2, initial Z-score < 2 was associated with 14.3 times lower risk of developing sinus Z-score ≥ 3 at follow up. Sinus Z-score overall decreased by age, and males had a higher Z-score than females (ß = 0.72, SE = 0.14, p < 0.001). Though only a few patients had a Z-score > 4, and patients with initial Z-scores < 2 seem unlikely to develop clinically significant disease, screening practices remain incompletely defined such that periodic evaluation appears warranted.

RESUMO

This study examined prevalence of childhood overweight and obesity (ov/ob) and central obesity in five mega-cities across China (Beijing, Shanghai, Xi'an, Nanjing and Chengdu); described parental perceptions of children's ideal body image (IBI); and prospectively examined associations between parental perception of child IBI and child weight changes over 3 years. In this NIH-funded, open cohort study, data were collected from students and their parents in 2015, 2016 and 2017 (n = 3298, in 3 waves). Cross-sectional analysis included all 3298 children; longitudinal data analysis used mixed effects models and included 1691 children aged 6-17 years with ≥two body mass index (BMI) measurements during 2015-2017. Ov/ob prevalence based on Chinese age-sex-specific BMI cut-points was 30.0%. Based on waist-to-height ratio (WHtR), the abdominal obesity rate was 19.8%. Parents reported different preferred IBI for boys vs girls, being about 3 times more likely to select ov/ob as ideal for boys than for girls (4.5% vs 1.5%, respectively, P < .001). In longitudinal analysis, children whose parents selected ov/ob as ideal had higher BMI Z-scores and WHtR increase over time than those whose parents selected an average body image (ß [SE] = 0.042 [0.011], and ß [SE] = 0.010 [0.004], respectively, all P < .05). Ov/ob rates were high among children in major cities in China. Chinese parents preferred a heavier ideal body image for their boys. Health promotion programs should help empower parents and their children to develop appropriate body images and maintain healthy body weight.
