Adolescents with eating disorders during the COVID-19 pandemic: Changes in social ties and healthcare modalities

Introduction. The COVID-19 pandemic has had a profound impact on the health of young people worldwide, especially on people with eating disorders (EDs) due to the stress, anxiety, and changes experienced in access to health care. Objective. To explore adolescents' perceptions on changes in their social ties and the modalities of health care for patients with EDs. Population and methods. Qualitative study using in-depth interviews with adolescents with EDs seen at a teaching hospital during the COVID-19 pandemic. Results. Fifteen adolescents were interviewed; their mean age was 18 years; 93% were girls. Anorexia nervosa was observed in 86.6%. The most relevant negative aspects perceived were discomfort with family life (80%) and dissatisfaction with social media content regarding body image and dieting (73%). The aspects perceived as positive were peer support (66%) and improvements in eating habits (66%). The main change identified regarding the management before the COVID-19 pandemic was online followup by the mental healthcare team (73%). Conclusion. The adolescent population with EDs during the mandatory social isolation period reported discomfort with family life and dissatisfaction with social media content regarding body image and dieting. Notwithstanding this, adolescents highlighted peer support and improvements in their eating habits as positive aspects.

[Treatment of eating disorders in adolescents: case series]

Eating disorders are highly prevalent diseases in adolescence and have an impact on overall health. The objective was to describe the evolution and treatment of eating disorders in adolescents. Adolescents under 18 years of age with at least 6 months of follow-up and treated by an interdisciplinary team were studied. Forty one adolescents were included, 23 presented anorexia nervosa, 9 unspecified eating disorders, 7 bulimia nervosa and 2 binge eating disorders. Thirty five percent of patients with anorexia nervosa required hospitalization for complications of malnutrition. Sixty nine percent of the patients with anorexia nervosa, 57 % with bulimia nervosa, and 78 % with unspecified eating disorders had total or partial remission and there were no deceased patients. The majority presented a favorable evolution with the treatment.

Retinol-binding protein 4 and nicotinamide phosphoribosyltransferase/visfatin in rat obesity models

Retinol-binding protein 4 (RBP4) and nicotinamide phosphoribosyltransferase/visfatin (Nampt/visfatin) are adipocyte-secreted proteins (adipokines) whose relevance to the metabolic syndrome and regulation in obesity remain controversial. Here, we tested the hypothesis that adipose tissue expression and circulating levels of these two adipokines are elevated in obesity by analyzing their changes in both a genetic and a diet-induced model of obesity in the rat (obese FA/ FA Zucker rats and Wistar rats fed a cafeteria diet, respectively). Compared with lean controls, obese FA/ FA rats were hyperleptinemic, hyperinsulinemic, and insulin resistant and had reduced RBP4 serum levels and mRNA levels in adipose depots, unchanged Nampt/visfatin serum levels, and reduced Nampt/visfatin mRNA levels selectively in the inguinal adipose depot. Cafeteria diet-induced obesity resulted in increased fed blood glucose levels, a variable degree of insulin resistance, unchanged serum Nampt/visfatin and RBP4 levels, and reduced mRNA levels of both adipokines in several adipose depots. Hence, increases in RBP4 or Nampt/visfatin do not accompany obesity and insulin resistance in the models examined.

Myocardial perfusion defects in patients with autoimmune diseases: a prospective study. Analysis of two diagnostic tests

A significant correlation between autoimmune diseases and premature or accelerated coronary atherosclerosis has been found. The objectives of the study were: (a) to evaluate myocardial perfusion defects in patients with autoimmune diseases by contrast echocardiography and nuclear imaging; and (b) to evaluate the prevalence of alterations in subclinical myocardial perfusion defects in autoimmune diseases. Myocardial perfusion in 37 patients was evaluated by contrast echocardiography at rest and with dobutamine and with nuclear imaging. The agreement between the two diagnostic tests at rest was 0.72 (P < 0.0001) and with dobutamine was 0.65 (P < 0.0001). The prevalence of abnormalities in myocardial perfusion in autoimmune diseases by contrast echocardiography and nuclear imaging was 27% and in patients with primary antiphospholipid syndrome was 30%. We concluded that there is a high level of agreement between contrast ecocardiography and nuclear imaging for assessment of myocardial perfusion defects in patients with autoimmune diseases, and their prevalence is similar to that reported in the literature.

Surgical treatment for secundum atrial septal defects in patients >40 years old. A randomized clinical trial

We prospectively examined whether surgical treatment of secundum atrial septal defects (ASDs) in patients > or =40 years old improves their long-term clinical outcome. Surgical treatment of secundum ASDs in adults > 40 years old is a subject of controversy because of the perception of good long-term clinical outcomes in patients with unrepaired ASDs and the lack of data from randomized trials. We recruited 521 patients > 40 years old with secundum ASDs referred for treatment; 48 were excluded. Patients were randomly assigned to surgical closure (n = 232) or medical treatment (n = 241). The primary and secondary end points were a composite of major cardiovascular events (death, pulmonary embolism, major arrhythmic event, embolic cerebrovascular event, recurrent pulmonary infection, functional class deterioration or heart failure) and overall mortality, respectively. We assessed possible prognostic markers. The analysis was performed on an intention-to-treat basis. The median follow-up period was 7.3 years (range 2 to 13). The risk of having the primary end point was significantly higher in the medical group, which had a univariate hazards ratio of 1.99 (95% confidence interval [CI] 1.23 to 3.22) and a multivariate hazards ratio of 1.85 (95% CI 1.08 to 3.17). Although the survival analysis did not reveal differences in overall mortality between the surgical and medical treatments (hazards ratio 1.71, 95% CI 0.76 to 3.86), the multivariate analysis, adjusted by age at entry, mean pulmonary artery pressure and cardiac index, demonstrated significant differences between the study groups (hazards ratio 4.09, 95% CI 1.41 to 11.89). Surgical closure was superior to medical treatment in improving both the composite of major cardiovascular events and overall mortality in patients > 40 years old with secundum ASDs. This superiority was related to the mean pulmonary artery pressure, age at diagnosis and cardiac index. Because of the higher risk of morbidity and mortality, we believe that anatomic closure should always be attempted as the initial treatment for ASDs in adults > 40 years old with pulmonary artery systolic pressure < 70 mm Hg and a pulmonary/systemic output ratio > or =1.7. The operation must be performed as soon as possible, even if the symptoms or the hemodynamic impact seems to be minimal.

The adult patient with Ebstein anomaly. Outcome in 72 unoperated patients

Knowledge of the long-term outcome in unoperated adult patients with Ebstein anomaly is limited, and the therapeutic approach is still controversial. We studied unoperated adult patients with Ebstein anomaly to define the patterns of presentation, anatomic characteristics, outcome, and predictive factors for survival. Seventy-two unoperated survivors of Ebstein anomaly aged over 25 years attended from 1972 to 1997 were reviewed and followed-up from 1.6 to 22.0 years. Patients were classified in 3 groups of severity according to the echocardiographic appearance of the septal leaflet attachment of tricuspid valve. The mean age at diagnosis was 23.9 +/- 10.4 years, and the most common clinical presentation was an arrhythmic event (51.4%). There were 30 (42%) deaths, including 6 from arrhythmia, 12 related to heart failure, 7 sudden, 2 unrelated, and 3 unascertained. According to Cox regression analysis, predictors of cardiac-related death included age at diagnosis (hazard ratio 0.89 for each year of age, 95% confidence intervals CI[ 0.84-0.94), male sex (3.93, 95% CI, 1.50-10.29), degree of echocardiographic severity (3.34, 95% CI, 1.78-6.24), and cardiothoracic ratio > or = 0.65 (3.57, 95% CI, 1.15-11.03). During follow-up, morbidity was mainly related to arrhythmia and refractory late hemodynamic deterioration. The magnitude of tricuspid regurgitation, cyanosis, and the New York Heart Association (NYHA) functional class at time zero were significant risk factors according to the univariate analysis, but not after multivariable confrontation. The results of this study suggest that pattern of presentation, clinical course, and prognosis of unoperated adult patients with Ebstein anomaly are influenced by several factors. Although the initial symptoms are usually mild and commonly related to supraventricular arrhythmias, these are not associated with the long-term outcome. The severity of the morbid anatomy was the main determinant of survival only in extreme cases, but not in those with mild or moderate deformations, which are more common in adults. Other independent risk factors such as cardiothoracic ratio, sex, age at diagnosis, and the echocardiographic evaluation may help to determine the therapeutic approach. Adult patients with Ebstein anomaly should not be considered as a simple low-risk group.
