- Adolescent obesity treatments: news, views, and evidence(2021) COMINATO, Louise; FRANCO, Ruth; DAMIANI, DurvalObesity is a complex and multifactorial disease that is influenced by physiological, environmental, socioeconomic, and genetic factors. In recent decades, this serious disease has impacted a large number of adolescents as a result of lifestyle factors. A lack of exercise and the consumption of excessive calories from an inadequate diet are the main contributors to adolescent obesity. However, genetic and hormonal factors might also play a role. The short- and long-term consequences of this disease include chronic issues such as type 2 diabetes and cardiovascular disorders and an increase in early mortality rates. Although it is a serious disease, obesity in adolescents can be controlled with diet and exercise. When these lifestyle changes do not obtain the expected results, we can intensify the treatment by adding medication to the practice of diet and exercise. Additionally, for more severe cases, bariatric surgery can be an option. The purpose of this review is to clarify the current epidemiology, risks, and comorbidities and discuss news about the main treatments and the necessary improvements in this context.

- Cardiac autonomic control during non-REM and REM sleep stages in paediatric patients with Prader-Willi syndrome(2021) BRITO, Leandro C.; QUEIROGA, Thereza; FRANCO, Ruth R.; PASSONE, Caroline G. B.; LOPES, Maria-Cecilia; SHEA, Steven A.; BUENO, Clarissa; SOSTER, Leticia M. S. F. A.Cardiac death is the second most prevalent cause in Prader-Willi syndrome (PWS). Paediatric patients with PWS often present cardiac autonomic dysfunction during wakefulness, obesity and sleep-disordered breathing. However, the extent of cardiac autonomic modulation during sleep in PWS has not been documented. The objective of this study was to assess alterations in cardiac autonomic modulation of paediatric patients with PWS during different sleep stages. Thirty-nine participants in three groups: 14 PWS, 13 sex and age-matched lean controls (LG) and 12 obese-matched controls (OB). All participants underwent overnight polysomnography, including continuous electrocardiogram recordings. Heart rate variability (HRV) was analysed during representative periods of each sleep stage through time and frequency domains calculated across 5-min periods. Between-within ANOVAs were employed (p < .05). The results show that total HRV was lower in PWS than OB and LG during slow-wave sleep (SWS) (standard deviation of all NN intervals [SDNN] ms,p = .006). Parasympathetic modulation assessed by time-domain analysis was lower during SWS in PWS compared to both OB and LG (square root of the mean of the sum of the squares of differences between adjacent NN intervals [RMSSD] ms,p = .004; SDSD, standard deviation of differences between adjacent NN intervals [SDSD] ms,p = .02; number of adjacent NN intervals differing by >50 ms [NN50] ms,p = .03; proportion of adjacent NN intervals differing by >50 ms [pNN50] ms,p = .01). Sympathovagal balance assessed by frequency-domain analysis was lower during both N2 and SWS than during the rapid eye movement (REM) sleep stage, but not different among groups. In conclusion, this group of paediatric patients with PWS had impaired cardiac autonomic balance due to reduced parasympathetic modulation during SWS. This result could imply an underlying increased cardiovascular risk in PWS even during early age and independent of obesity.
- Poor Sleep quality and health-related quality of life impact in adolescents with and without chronic immunosuppressive conditions during COVID-19 quarantine(2021) HELITO, Alberto C.; LINDOSO, Livia; SIECZKOWSKA, Sofia M.; ASTLEY, Camilla; QUEIROZ, Ligia B.; ROSE, Natalia; SANTOS, Claudia Renata P.; BOLZAN, Thalis; PERALTA, Rita Maria I. A.; FRANCO, Ruth R.; COMINATO, Louise; PEREIRA, Rosa Maria R.; TANNURI, Uenis; CAMPOS, Lucia Maria A.; LOURENCO, Benito; TOMA, Ricardo K.; MEDEIROS, Karina; WATANABE, Andreia; GRANGEIRO, Patricia Moreno; FARHAT, Sylvia C.; CASELLA, Caio B.; V, Guilherme Polanczyk; GUALANO, Bruno; SILVA, Clovis A.OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p < 0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.
- Transcranial Direct Current Stimulation for Prader-Willi Syndrome(2021) AZEVEDO, Caroline C.; TREVIZOL, Alisson Paulino; GOMES, July S.; AKIBA, Henrique; FRANCO, Ruth R.; SIMURRO, Paula B.; IANNI, Renata M.; GRIGOLON, Ruth B.; BLUMBERGER, Daniel M.; DIAS, Alvaro M.Background: Given the limited therapeutic options for Prader-Willi syndrome (PWS), we conducted an open-label clinical trial to evaluate the effects of transcranial direct current stimulation (tDCS) for hyperphagia, food craving, and aberrant behaviors on this population. Methods: Twelve subjects with PWS (11-35 years old) were included. The subjects underwent 10 daily 20-minute sessions of tDCS in 2 weeks. The anode was positioned over the left dorsolateral prefrontal cortex, and the cathode over the contralateral region. Results: We observed amelioration of hyperphagic and food craving symptoms (P < 0.05), as well as amelioration of behavioral symptoms measured with the Aberrant Behavior Checklist (P < 0.05). Discussion: To our knowledge, this is the first proof-of-concept trial to report the positive effects of increasing excitability of the left dorsolateral prefrontal cortex, using tDCS, for the behavioral, hyperphagia, and food craving symptoms in PWS, which is a low-cost, well-studied, safe alternative for brain stimulation.
