RESUMEN

Cardiac complications are a major concern in patients with anorexia nervosa (AN) which contribute to morbidity and mortality. However, limited information exists regarding risk factors for the development of these complications. Our objective was to investigate the prevalence and associated risk factors of cardiac involvement among children and adolescents with AN admitted to a tertiary pediatric hospital. We collected demographic, clinical, and laboratory data from individuals with AN hospitalized between 2011 and 2020 in Schneider Children's Medical Center in Israel. Diagnosis was based on established criteria (DSM-5). Patients with other co-morbidities were excluded. Cardiac investigations included electrocardiograms (ECG) and echocardiograms. We conducted correlation tests between cardiac findings and clinical and laboratory indicators. A total of 403 AN patients (81.4% were females) with a median age of 15 ± 2 years were included in the study. Sinus bradycardia was the most common abnormality, observed in 155 (38%) participants. Echocardiogram was performed in 170 (42.2%) patients, of whom 37 (22%) demonstrated mild cardiac aberrations. Among those aberrations, 94.6% could be attributed to the current metabolic state, including pericardial effusion (15.3%) and valve dysfunction (8.8%). Systolic or diastolic cardiac dysfunction, tachyarrhythmias, or conduction disorders were not observed. Patients with new echocardiographic aberration had significantly lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension was higher in this group. CONCLUSIONS: The prevalence of cardiac involvement, except for sinus bradycardia, was notably low in our cohort. The presence of cardiac aberrations is correlated with several clinical variables: lower body mass index (BMI) and the presence of amenorrhea and hypotension at admission. Patients presenting with these variables may be at high risk for cardiac findings per echocardiography. Dividing the patients into high and low risk groups may enable targeted evaluation, while avoiding unnecessary cardiac investigations in low-risk patients. WHAT IS KNOWN: • Cardiac involvement in anorexia nervosa (AN) patients is a major concern, which contributes to morbidity and mortality. • It is unknown which patients are prone to develop this complication. WHAT IS NEW: • Cardiac complications in our cohort are less frequent compared to previous studies, and it is correlated with lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension.

RESUMEN

Youth with anorexia nervosa (AN) or atypical anorexia nervosa (AAN) and premorbid overweight/obesity are particularly vulnerable to diagnostic delays, yet research about this patient subset is lacking. This study aimed to compare mental health and demographic characteristics of patients with AN/AAN and premorbid overweight/obesity to patients with premorbid normal weight. Retrospective chart review identified 253 patients (aged 10-22) hospitalized for medical complications of AN/AAN between 2013 and 2020, including 29.6% (n = 75) with and 70.4% (n = 178) without premorbid overweight/obesity. Analyses revealed that patients with AN/AAN and premorbid overweight/obesity were more often cisgender male (24% vs. 8.4%), diagnosed with AAN (62.7% vs. 32%), and had lost a greater percent of body weight (29% vs. 16.4%) than premorbid normal weight counterparts. No significant differences were found for illness duration (10.1 months vs 9.3 months), psychiatric comorbidities (42.7% vs. 32.2%) or psychotropic medication use (25.3% vs. 19.2%), past mental health treatment (44.6% vs. 37.5%), or family history of eating disorders (22.7% vs. 20.8%). Our findings suggest that when relying on historical records, patients hospitalized for medical complications of AN/AAN have similar characteristics across the weight spectrum.

RESUMEN

In this randomized pilot study, we examined the effects of yoga intervention on axial and peripheral bone mineral density (BMD), disordered eating cognitions, anxiety, and depression in adolescent girls with anorexia nervosa (AN). Fifteen young women aged 13-18 years with AN or atypical AN were randomized to either a Yoga group (n = 7), including twice-weekly yoga for 24 weeks plus standard outpatient care, or Non-Yoga group (n = 8), who received standard outpatient care alone. Data from anthropometrics, mental health and eating behavior questionnaires, dual-energy x-ray absorptiometry, and peripheral quantitative computed tomography measurements were obtained at baseline and 6 months. The adjunct of yoga to standard treatment resulted in statistically significant improvement of axial BMD, depression, and disordered eating cognitions in comparison to the Non-Yoga group. In conclusion, a gentle yoga intervention may be beneficial for improving bone and mental health in adolescent females with AN.

RESUMEN

AIM: The cerebral vasculature may be susceptible to the adverse effects of type 2 diabetes. In this pilot study, we compared cerebral blood flow (CBF) in youth with type 2 diabetes to obese, euglycemic controls, and explored the association between CBF and a non-invasive measure of atherosclerosis, carotid intima-medial thickness (IMT). METHODS: Global and regional CBF were compared between youth with type 2 diabetes (mean age 16.7 ± 2.0 years, n = 20) and age, race, and sex similar obese youth without diabetes (17.4 ± 1.9 years, n = 19) using arterial spin labeling magnetic resonance imaging. Mean CBF values were compared between groups. Voxel-wise results were evaluated for statistical significance (p < 0.05) after adjustment for multiple comparisons. Carotid IMT in the type 2 diabetes group was correlated with CBF. RESULTS: Compared to obese controls, the type 2 diabetes group had significantly lower global CBF (49.7 ± 7.2 vs. 63.8 ± 11.5 ml/gm/min, p < 0.001). Significantly lower CBF was observed in multiple brain regions for the type 2 diabetes group, while no regions with higher CBF were identified. In the type 2 diabetes group, carotid IMT was inversely correlated with CBF, both globally (r = -0.70, p = 0.002) and in regional clusters. CONCLUSIONS: In this pilot study, lower CBF was seen in youth with type 2 diabetes compared to youth with obesity and IMT was inversely correlated with CBF. Cerebrovascular impairment may be present in youth with type 2 diabetes. These findings could represent a mechanistic link to explain previously reported brain volume and neurocognitive differences.

RESUMEN

Social distancing and quarantines have major negative psychological implications. Our aim was to study the rate of pediatric hospitalizations due to anorexia nervosa (AN) during the first year of coronavirus disease 2019 (COVID-19) pandemic as compared to previous years, with regard to clinical and laboratory parameters. This is a retrospective study in a tertiary pediatric hospital in Israel. Data regarding inpatient hospitalizations due to AN were retrieved, then epidemiological, clinical, and laboratory parameters compared. During the entire study period, 275 hospitalizations were due to AN: 94 patients were admitted during the 12 months of the pandemic as compared to a yearly mean of 45.25 during 2015-2019, resulting in a 2.4-fold increase (p < 0.001). The mean admission age and female predominance were similar in the two study groups. The weight of the patients at admission was higher during the COVID-19 period (44.5 kg vs. 41.2 kg, p = 0.004), and fewer patients had clinical signs typical of AN upon physical examination (p = 0.022). There was a 35% reduction in median hospitalization duration (9 days [IQR 8.21] in 2020-2021 and 14 [IQR 6, 16.75] days in 2015-2019, p = 0.01). No other differences were found. CONCLUSIONS: During the first year of the COVID-19 pandemic, there was a significant increase in the number of adolescents hospitalized with AN. Nevertheless, disease characteristics were not more severe as compared to the preceding 5 years. WHAT IS KNOWN: • Social distancing and quarantines were announced during the COVID-19 pandemic in numerous countries. These measures have potential negative psychological effects on adolescents. WHAT IS NEW: • During the COVID-19 pandemic period, there was an increase in the number of hospitalizations of adolescents with AN, although disease characteristics were not more severe as compared to the preceding 5 years.

RESUMEN

Adolescents with overweight/obesity are at risk for vitamin D insufficiency and deficiency. Both overweight/obesity and vitamin D insufficiency/deficiency may predispose to fractures. We enrolled 103 participants (53.3% females, 15.9 ± 2.2 years) in a retrospective case-control study to determine whether an association exists between fractures and a low 25-hydroxyvitamin D (25[OH]D) among adolescents whose body mass index (BMI) ≥ 85 percentile. Cases (n = 28) sustaining a low/medium impact fracture were matched to controls (n = 75) without a fracture history. A conditional-logistic regression analysis addressing the common vitamin D insufficiency/deficiency cutoffs was used. Overweight, obesity, and significant obesity rates were 10.7%, 53.4%, and 35.9%, respectively. Mean (±SD) 25(OH)D was 16.5 ± 6.4 ng/mL. In all, 25(OH)D insufficiency rates (level <20 ng/mL) were 70.5%. Matched cases and controls had similar 25(OH)D insufficiency/deficiency rates (P > .05). Controlling for race and seasonality showed no association between fractures and 25(OH)D insufficiency/deficiency (P > .05). These data suggest that fractures are not associated with low 25(OH)D levels among adolescents whose BMI ≥ 85th percentile.

RESUMEN

Systematic data are lacking on pediatric long COVID. This study prospectively assessed 90 children with persistent symptoms who presented to a designated multidisciplinary clinic for long COVID. In nearly 60%, symptoms were associated with functional impairment at 1-7 months after the onset of infection. A comprehensive structured evaluation revealed mild abnormal findings in approximately half the patients, mainly in the respiratory aspect.

RESUMEN

PURPOSE: Previous reports have shown limbic dysregulation in patients with restrictive eating disorders (EDs). This study investigated functional responses in brain systems to visual food stimuli and their correlation with psychological and behavioral outcomes. METHODS: A total of 18 females, aged 13-18 years, who were diagnosed with anorexia nervosa (n = 11) or atypical anorexia nervosa (n = 7), completed functional magnetic resonance imaging during a visual food paradigm. Stimuli included four food types and one nonfood. Anxiety and disordered eating cognitions were assessed using the State-Trait Anxiety Inventory and Eating Attitude Test (EAT-26). Analyses were performed to obtain contrasts among different food categories and test their correlations with cognitive and behavioral scores. RESULTS: Contrasts of foods versus nonfood generally resulted in positive responses in occipital regions and negative responses in temporal and parietal gyri. Contrast of sweets versus nonfood, in particular, elicited additional activation in the hippocampus. Contrasting sweet to nonsweet food, the orbitofrontal cortex and anterior cingulate cortex (ACC) were activated. Contrast of all foods versus nonfood had a positive correlation with State-Trait Anxiety Inventory-state scores in the orbitofrontal cortex and ACC. Finally, the sweet versus nonsweet contrast correlated positively with EAT-26 in ACC and other frontal areas. CONCLUSIONS: Visual food stimuli elicited brain responses in limbic centers, and sweet foods extended activation to other limbic domains. Sweet food contrast correlated to EAT-26 in regions comprising the default mode network tied to introspection. Thus, we conclude that visual food stimuli produce activation in limbic-regulating regions in patients with restrictive EDs that correlate with disordered-eating cognitions and behaviors.
