- Quality of life, fatigue, sleep quality, and mental health in systemic lupus erythematosus patients with a high cardiovascular risk profile(2023) MAZZOLANI, Bruna Caruso; SMAIRA, Fabiana Infante; SIECZKOWSKA, Sofia; ROMERO, Marina; RIBEIRO, Thaina Toledo; AMARANTE, Milla Cordeiro; PASOTO, Sandra; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; BENATTI, Fabiana Braga; BONFA, Eloisa; ROSCHEL, Hamilton; GUALANO, BrunoSystemic lupus erythematosus (SLE) patients report worse health-related quality of life (HRQL), fatigue, anxiety, depression, and sleep quality, when compared to the general population and other chronic diseases. Furthermore, cardiometabolic diseases are highly prevalent in SLE and are also associated with these parameters. Thus, it is plausible to suggest that SLE patients with a high cardiovascular risk may report worse results for these parameters. The aim of the study is to describe HRQL, fatigue, anxiety and depression symptoms, and sleep quality in a sample of SLE patients with a high cardiovascular risk profile (i.e., BMI between 25 and 40 kg/m2 and/or dyslipidemia, hypertension, or diabetes). This was a cross-sectional study where patients were assessed for (i) demographic, anthropometric, and disease-related parameters, (ii) HRQL, (iii) fatigue, (iv) anxiety and depression symptoms, and (v) sleep quality. One-hundred patients completed the study; however, only 87 patients were assessed for sleep quality data. Patients averaged 41.7 & PLUSMN; 9 years, and most patients were classified as overweight/obese (87%). SF-36 scores for physical and mental components summary were 51.3 & PLUSMN; 9.6 and 54.2 & PLUSMN; 15.6, respectively, with ""bodily pain"" and ""role emotional"" presenting the lower scores. The total SLEQOL score was 105.1 & PLUSMN; 42.0, with lower scores reported for ""self-image"" and ""mood."" Fatigue score was 30.8 & PLUSMN; 8.9, and 78% and 93% reported severe symptoms of anxiety and depression, respectively. The average sleep effectiveness was 82.9 & PLUSMN; 6.6%. Sleep latency, total time in bed (TTiB), and total sleep time (TST) were 8.4 & PLUSMN; 8.9, 495.8 & PLUSMN; 79.7, and 409.7 & PLUSMN; 69.9 min, respectively. Patients reported an average of 17.8 & PLUSMN; 6.2 WE, with 4.5 & PLUSMN; 1.5 min duration and a WASO of 77.7 & PLUSMN; 36.6 min. Despite similar HRQL, fatigue, and sleep quality parameters to those reported by other SLE populations, SLE patients with a high cardiovascular risk had a higher prevalence of depression and anxiety. Understanding SLE patients' quality of life and psychological symptoms is of utmost importance to improve disease management. The findings of this study highlight the need for more intensive and global care regarding mental health when considering a high cardiovascular risk in SLE.

- Disordered Eating Attitudes and Food Choice Motives Among Individuals Who Follow a Vegan Diet in Brazil(2023) MAZZOLANI, Bruna Caruso; SMAIRA, Fabiana Infante; ESTEVES, Gabriel P.; SANTINI, Martin Hindermann; LEITAO, Alice Erwig; ANDRE, Heloisa C. Santo; GUALANO, Bruno; ROSCHEL, HamiltonIMPORTANCE It remains controversial whether adhering to a vegan diet may be associated with a higher prevalence of disordered eating. Also, main food choice motives and their association with disordered eating in this population are still unknown. OBJECTIVE To determine the association between disordered eating attitudes and food choice motives of individuals who follow a vegan diet. DESIGN, SETTING, AND PARTICIPANTS This is a cross-sectional online survey conducted between September 2021 and January 2023. Individuals of both sexes, aged 18 years or older, following a vegan diet for at least 6 months, currently living in Brazil were recruited through advertisements on social media. EXPOSURE Adherence to a vegan diet and food choice motives. MAIN OUTCOMES AND MEASURES Disordered eating attitudes and food choice motives. RESULTS Nine hundred seventy-one participants completed the online survey. Median (IQR) age and BMI of participants was 29 (24-36) years and 22.6 (20.3-24.9), respectively, and 800 participants (82.4%) were female. Most participants (908 respondents [94%]) were categorized with the lowest level of disturbed eating attitudes. ""Need and hunger,"" ""liking,"" ""health,"" ""habits,"" and ""natural concerns"" were the most important food choice motives in this population, while ""affect regulation,"" ""social norms,"" and ""social image"" were the less important ones. Adjusted models showed that ""liking,"" ""need and hunger,"" and ""health"" were associated with lower levels of disordered eating attitudes, while ""price,"" ""pleasure,"" ""sociability,"" ""traditional eating,"" ""visual appeal,"" ""social norms,"" ""social image,"" ""weight control,"" and ""affect regulation"" were associated with higher levels of disordered eating attitudes. CONCLUSIONS AND RELEVANCE In this cross-sectional study, as opposed to previous suggestions, levels of disordered eating were very low among vegans, although certain food choice motives were associated with disordered eating attitudes. Understanding the motivations of adhering to diets that may impose restrictions, which include vegan diets, may help tailor interventions focused on promoting healthy eating and preventing or treating disordered eating.
- Exercise modifies hypothalamic connectivity and brain functional networks in women after bariatric surgery: a randomized clinical trial(2023) MEREGE-FILHO, Carlos A. A.; GIL, Saulo S.; KIRWAN, John P.; MURAI, Igor H.; DANTAS, Wagner S.; NUCCI, Mariana P.; PASTORELLO, Bruno; LIMA, Alisson Padilha de; BAZAN, Paulo R.; PEREIRA, Rosa M. R.; SA-PINTO, Ana L. de; LIMA, Fernanda R.; BRUCKI, Sonia M. D.; CLEVA, Roberto de; SANTO, Marco A.; LEITE, Claudia da Costa; OTADUY, Maria Concepcion Garcia; ROSCHEL, Hamilton; GUALANO, BrunoBackgroundObesity is a disease that may involve disrupted connectivity of brain networks. Bariatric surgery is an effective treatment for obesity, and the positive effects on obesity-related conditions may be enhanced by exercise. Herein, we aimed to investigate the possible synergistic effects of Roux-en-Y Gastric Bypass (RYGB) and exercise training on brain functional networks. MethodsThirty women eligible for bariatric surgery were randomly assigned to a Roux-en-Y gastric bypass (RYGB: n = 15, age = 41.0 & PLUSMN; 7.3 years) or RYGB plus Exercise Training (RYGB + ET: n = 15, age = 41.9 & PLUSMN; 7.2 years). Clinical, laboratory, and brain functional connectivity parameters were assessed at baseline, and 3 (POST3) and 9 months (POST9) after surgery. The 6-month, three-times-a-week, exercise intervention (resistance plus aerobic exercise) was initiated 3 months post-surgery (for RYGB + ET). ResultsExercise superimposed on bariatric surgery (RYGB + ET) increased connectivity between hypothalamus and sensorial regions (seed-to-voxel analyses of hypothalamic connectivity), and decreased default mode network (DMN) and posterior salience (pSAL) network connectivity (ROI-to-ROI analyses of brain networks connectivity) when compared to RYGB alone (all p-FDR < 0.05). Increases in basal ganglia (BG) network connectivity were only observed in the exercised training group (within-group analyses). ConclusionExercise training is an important component in the management of post-bariatric patients and may improve the hypothalamic connectivity and brain functional networks that are involved in controlling food intake.
- Home-Based Exercise Training in the Recovery of Multisystem Inflammatory Syndrome in Children: A Case Series Study(2023) ASTLEY, Camilla; LEAL, Gabriela Nunes; GIL, Saulo; SUGUITA, Priscila; FINK, Thais; BAIN, Vera; PEREIRA, Maria Fernanda Badue; MARQUES, Heloisa Helena; SIECZKOWSKA, Sofia; PRADO, Danilo; LIMA, Marcos Santos; CARNEIRO, Camila G.; BUCHPIGUEL, Carlos Alberto; SILVA, Clovis Artur; GUALANO, BrunoObjective: To assess the potential therapeutic role of exercise on health-related quality of life, assessed by the Pediatric Outcomes Data Collection Instrument (PODCI), coronary flow reserve (CFR), cardiac function, cardiorespiratory fitness, and inflammatory and cardiac blood markers in multisystemic inflammatory syndrome in children (MIS-C) patients. Methods: This is a case series study of a 12-wk, home-based exercise intervention in children and adolescents after MIS-C diagnosis. From 16 MIS-C patients followed at our clinic, 6 were included (age: 7-16 years; 3 females). Three of them withdrew before the intervention and served as controls. The primary outcome was health-related quality of life, assessed PODCI. Secondary outcomes were CFR assessed by 13N-ammonia PET-CT imaging, cardiac function by echocardiography, cardiorespiratory fitness, and inflammatory and cardiac blood markers. Results: In general, patients showed poor health-related quality of life, which seemed to be improved with exercise. Additionally, exercised patients showed improvements in coronary flow reserve, cardiac function, and aerobic conditioning. Non-exercised patients exhibited a slower pattern of recovery, particularly in relation to health-related quality of life and aerobic conditioning. Conclusions: Our results suggest that exercise may play a therapeutic role in the treatment of post-discharge MIS-C patients. As our design does not allow inferring causality, randomized controlled trials are necessary to confirm these preliminary findings.
- Impact of COVID-19 on physical and mental functioning in adolescents with disabilities in a sports nongovernmental organization(2023) LAURENTINO, Moises de Freitas; LINDOSO, Livia; ASTLEY, Camilla; LAVORATO, Sofia Simao Martins; IHARA, Bianca Pires; LIMA, Dandara Carvalho Casado de; GUALANO, Bruno; QUEIROZ, Ligia Bruni; PEREIRA, Rosa Maria Rodrigues; POLANCZYK, Guilherme Vanoni; CAMARGO, Olavo Pires de; SILVA, Clovis Artur; GRANGEIRO, Patricia MorenoObjective:This study aimed to assess physical and mental health, and health-related quality of life (HRQL) parameters in adolescents with physical disabilities enrolled in a sports nongovernmental organization (NGO) versus adolescents without disabilities during coronavirus disease 2019 (COVID-19) pandemic. Methods: This cross-sectional study included 30 adolescents with disabilities and 86 adolescents without disabilities who responded to an online questionnaire with sociodemographic data and self-rated healthcare routine information during the COVID-19 quarantine. Validated self-report versions of the Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0), Pittsburgh Sleep Quality Index (PSQI), and Pediatric Outcome Data Collection Instrument (PODCI) were also applied. Results: The median of emotional [4 (0-10) vs. 5 (0-10), p=0.018] and prosocial [7 (0-10) vs. 9 (3-10), p=0.006] problems was lower in adolescents with disabilities versus adolescents without disabilities. Adolescents with disabilities had significantly lower global function [68 (21-99) vs. 94 (67-100), p<0.001] and higher happiness scores in the PODCI scale [90 (65-100) vs. 80 (0-100), p=0.016] compared to controls. Logistic regression analysis demonstrated that physical activity/week (OR=1.03; 95%CI 1.01-1.05, p=0.002) was higher in adolescents with disabilities compared to adolescents without disabilities. However, housework activities (OR=0.14; 95%CI 0.04-0.43, p=0.001) and screen time >= 3 h/day (OR=0.09; 95%CI 0.02-0.38, p=0.001) were lower in adolescents with disabilities compared to adolescents without disabilities. Conclusion: Adolescents with disabilities attending a sports NGO were not at higher risk of adverse health-related indicators; despite showing reduced physical function, they reported more physical activity, higher happiness, and less screen time compared to adolescents without disabilities during the COVID-19 pandemic.
- Effects of a 16-week home-based exercise training programme on health-related quality of life, functional capacity, and persistent symptoms in survivors of severe/critical COVID-19: a randomised controlled trial(2023) LONGOBARDI, Igor; GOESSLER, Karla; JR, Gersiel Nascimento de Oliveira; PRADO, Danilo Marcelo Leite do; SANTOS, Jhonnatan Vasconcelos Pereira; MELETTI, Matheus Molina; ANDRADE, Danieli Castro Oliveira de; GIL, Saulo; BOZA, Joao Antonio Spott de Oliveira; LIMA, Fernanda Rodrigues; GUALANO, Bruno; ROSCHEL, HamiltonBackground Long-lasting effects of COVID-19 may include cardiovascular, respiratory, skeletal muscle, metabolic, psychological disorders and persistent symptoms that can impair health-related quality of life (HRQoL). We investigated the effects of a home-based exercise training (HBET) programme on HRQoL and health-related outcomes in survivors of severe/critical COVID-19. Methods This was a single-centre, single-blinded, parallel-group, randomised controlled trial. Fifty survivors of severe/ critical COVID-19 (5 +/- 1 months after intensive care unit discharge) were randomly allocated (1:1) to either a 3 times a week (similar to 60-80min/session), semi-supervised, individualised, HBET programme or standard of care (CONTROL). Changes in HRQoL were evaluated through the 36-Item Short-Form Health Survey, and physical component summary was predetermined as the primary outcome. Secondary outcomes included cardiorespiratory fitness, pulmonary function, functional capacity, body composition and persistent symptoms. Assessments were performed at baseline and after 16 weeks of intervention. Statistical analysis followed intention-to-treat principles. Results After the intervention, HBET showed greater HRQoL score than CONTROL in the physical component summary (estimated mean difference, EMD: 16.8 points; 95% CI 5.8 to 27.9; effect size, ES: 0.74), physical functioning (EMD: 22.5 points, 95% CI 6.1 to 42.9, ES: 0.83), general health (EMD: 17.4 points, 95%CI 1.8 to 33.1, ES: 0.73) and vitality (EMD: 15.1 points, 95%CI 0.2 to 30.1, ES: 0.49) domains. 30-second sit-to-stand (EMD: 2.38 reps, 95%CI 0.01 to 4.76, ES: 0.86), and muscle weakness and myalgia were also improved in HBET compared with CONTROL (p<0.05). No significant differences were seen in the remaining variables. There were no adverse events. Conclusion HBET is an effective and safe intervention to improve physical domains of HRQoL, functional capacity and persistent symptoms in survivors of severe/critical COVID-19. Trial registration number NCT04615052.
- No Associations Between Physical Activity and Immunogenicity in SARS-CoV-2 Seropositive Patients With Autoimmune Rheumatic Diseases Prior to and After Vaccination(2023) SMAIRA, Fabiana Infante; MAZZOLANI, Bruna Caruso; LEMES, italo Ribeiro; SILVA, Rafael Pires da; PINTO, Ana J.; SIECZKOWSKA, Sofia M.; AIKAWA, Nadia E.; PASOTO, Sandra G.; MEDEIROS-RIBEIRO, Ana C.; SAAD, Carla G. S.; YUK, Emily F. N.; SILVA, Clovis A.; SWINTON, Paul; KUPA, Leonard de Vinci Kanda; HALLAL, Pedro C.; ROSCHEL, Hamilton; GUALANO, Bruno; BONFA, EloisaAim: To investigate the association between physical activity and immunogenicity among SARS-CoV-2 seropositive patients with autoimmune rheumatic diseases prior to and following a 2-dose schedule of CoronaVac (Sinovac inactivated vaccine). Methods: This was a prospective cohort study within an open-label, single-arm, phase 4 vaccination trial conducted in Sao Paulo, Brazil. In this substudy, only SARS-CoV-2 seropositive patients were included. Immunogenicity was assessed by seroconversion rates of total anti-SARS-CoV-2 S1/S2 immunoglobulin G (IgG), geometric mean titers of anti-S1/S2 IgG, frequency of positive neutralizing antibodies, and neutralizing activity before and after vaccination. Physical activity was assessed through a questionnaire. Model-based analyses were performed controlling for age (<60 or>_60 y), sex, body mass index (<25, 25-30, and >30 kg/m2), and use of prednisone, immunosuppressants, and biologics. Results: A total of 180 seropositive autoimmune rheumatic disease patients were included. There was no association between physical activity and immunogenicity before and after vaccination. Conclusions: This study suggests that the positive association between physical activity and greater antibody responses seen in immunocompromised individuals following vaccination is overridden by previous SARS-CoV-2 infection, and does not extend to natural immunity.
- Acute Muscle Mass Loss Predicts Long-Term Fatigue, Myalgia, and Health Care Costs in COVID-19 Survivors(2023) GIL, Saulo; OLIVEIRA JUNIOR, Gersiel Nascimento de; SARTI, Flavia Mori; FILHO, Wilson Jacob; LONGOBARDI, Igor; TURRI, Jose Antonio Orellana; SHINJO, Samuel Katsuyuki; FERRIOLLI, Eduardo; -SILVA, Thiago Junqueira Avelino; BUSSE, Alexandre Leopold; GUALANO, Bruno; ROSCHEL, HamiltonObjective: We examined the impact of loss of skeletal muscle mass in post-acute sequelae of SARS-CoV-2 infection, hospital readmission rate, self-perception of health, and health care costs in a cohort of COVID-19 survivors.Design: Prospective observational study.Setting and Participants: Tertiary Clinical Hospital. Eighty COVID-19 survivors age 59 +/- 14 years were prospectively assessed.Methods: Handgrip strength and vastus lateralis muscle cross-sectional area were evaluated at hospital admission, discharge, and 6 months after discharge. Post-acute sequelae of SARS-CoV-2 were evaluated 6 months after discharge (main outcome). Also, health care costs, hospital readmission rate, and self -perception of health were evaluated 2 and 6 months after hospital discharge. To examine whether the magnitude of muscle mass loss impacts the outcomes, we ranked patients according to relative vastus lateralis muscle cross-sectional area reduction during hospital stay into either ""high muscle loss"" (-18 +/- 11%) or ""low muscle loss"" (-4 +/- 2%) group, based on median values. Results: High muscle loss group showed greater prevalence of fatigue (76% vs 46%, P =.0337) and myalgia (66% vs 36%, P = .0388), and lower muscle mass (-8% vs 3%, P < .0001) than low muscle loss group 6 months after discharge. No between-group difference was observed for hospital readmission and self -perceived health (P > .05). High muscle loss group demonstrated greater total COVID-19-related health care costs 2 ($77,283.87 vs. $3057.14, P = .0223, respectively) and 6 months ($90,001.35 vs $12, 913.27, P = .0210, respectively) after discharge vs low muscle loss group. Muscle mass loss was shown to be a predictor of total COVID-19-related health care costs at 2 (adjusted f3 = $10, 070.81, P < .0001) and 6 months after discharge (adjusted f3 = $9885.63, P < .0001). Conclusions and Implications: COVID-19 survivors experiencing high muscle mass loss during hospital stay fail to fully recover muscle health. In addition, greater muscle loss was associated with a higher frequency of post-acute sequelae of SARS-CoV-2 and greater total COVID-19-related health care costs 2 and 6 months after discharge. Altogether, these data suggest that the loss of muscle mass resulting from COVID-19 hospitalization may incur in an economical burden to health care systems.(c) 2022 AMDA -The Society for Post-Acute and Long-Term Care Medicine.
- Sleep quality is a predictor of muscle mass, strength, quality of life, anxiety and depression in older adults with obesity(2023) GENARIO, Rafael; GIL, Saulo; OLIVEIRA-JUNIOR, Gersiel; LEITAO, Alice Erwig; FRANCO, Tathiane; SALES, Ruan Celio dos Santos; FERRIOLLI, Eduardo; BUSSE, Alexandre Leopold; JACOB FILHO, Wilson; GUALANO, Bruno; ROSCHEL, HamiltonWe aimed to investigate associations between sleep quality with selected quantitative and qualitative parameters of health in older individuals with obesity. Cross-sectional assessment (n = 95 men/women; & GE; 65 years; BMI & GE; 30 kg/m(2)) of sleep quality, body composition, handgrip strength, quality-of-life, anxiety/depression. Mean PSQI score was 6.3. Poor sleepers (n = 49) presented lower appendicular lean mass (ALM) (16.2 vs 17.8 kg; p = 0.0273), ALM/BMI (0.47 vs 0.53 kg/BMI; p = 0.0085), fat mass (48.6 vs 46.6%; p = 0.0464), handgrip strength (19.7 vs 22.0 kgf; p = 0.0542) and handgrip/BMI (0.57 vs 0.66 kgf/BMI; p = 0.0242) than good sleepers. They also had higher anxiety (8.6 vs 5.6; p = 0.0100) and depression (4.8 vs 3.2; p = 0.0197) scores, worse health-related quality-of-life and lower scores in mental (62.8 vs 73.0; p = 0.0223) and physical (52.9 vs 67.3; p = 0.0015) domains. Adjusted models showed that PSQI was negatively associated with ALM (& beta; = - 0.13, 95% CI - 0.25; - 0.01) and health-related quality of life on physical (& beta; = - 2.76, 95% CI - 3.82; - 1.70) and mental (& beta; = - 2.25, 95% CI - 3.38; - 1.12) domains, and positively associated with anxiety (& beta; = 0.57; 95% CI 0.26; 0.87) and depression (& beta; = 0.31; 95% CI 0.13; 0.49). Poor sleep quality associates with impaired selected quantitative and qualitative parameters of health. Additionally, sleep quality was shown as an independent predictor of ALM, health-related quality-of-life, anxiety and depression in older individuals with obesity.
