- Omega-3 Fatty Acid Supplementation Improves Endothelial Function in Primary Antiphospholipid Syndrome: A Small-Scale Randomized Double-Blind Placebo-Controlled Trial(2018) FELAU, Sheylla M.; SALES, Lucas P.; SOLIS, Marina Y.; HAYASHI, Ana Paula; ROSCHEL, Hamilton; SA-PINTO, Ana Lucia; ANDRADE, Danieli Castro Oliveira de; KATAYAMA, Keyla Y.; IRIGOYEN, Maria Claudia; CONSOLIM-COLOMBO, Fernanda; BONFA, Eloisa; GUALANO, Bruno; BENATTI, Fabiana B.Endothelial cells are thought to play a central role in the pathogenesis of antiphospholipid syndrome (APS). Omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation has been shown to improve endothelial function in a number of diseases; thus, it could be of high clinical relevance in APS. The aim of this study was to evaluate the efficacy of n-3 PUFA supplementation on endothelial function (primary outcome) of patients with primary APS (PAPS). A 16-week randomized clinical trial was conducted with 22 adult women with PAPS. Patients were randomly assigned (1:1) to receive placebo (PL, n = 11) or n-3 PUFA (omega-3, n = 11) supplementation. Before (pre) and after (post) 16 weeks of the intervention, patients were assessed for endothelial function (peripheral artery tonometry) (primary outcome). Patients were also assessed for systemic markers of endothelial cell activation, inflammatory markers, dietary intake, international normalized ratio (INR), and adverse effects. At post, omega-3 group presented significant increases in endothelial function estimates reactive hyperemia index (RHI) and logarithmic transformation of RHI (LnRHI) when compared with PL (+13 vs. -12%, rho = 0.06, ES = 0.9; and +23 vs. -22%, rho = 0.02, ES = 1.0). No changes were observed for e-selectin, vascular adhesion molecule-1, and fibrinogen levels (rho > 0.05). In addition, omega-3 group showed decreased circulating levels of interleukin-10 (-4 vs. +45%, rho = 0.04, ES = -0.9) and tumor necrosis factor (-13 vs. +0.3%, rho = 0.04, ES = -0.95) and a tendency toward a lower intercellular adhesion molecule-1 response (+3 vs. +48%, rho = 0.1, ES = -0.7) at post when compared with PL. No changes in dietary intake, INR, or self-reported adverse effects were observed. In conclusion, 16 weeks of n-3 PUFA supplementation improved endothelial function in patients with well-controlled PAPS. These results support a role of n-3 PUFA supplementation as an adjuvant therapy in APS. Registered at http://ClinicalTrials.gov as NCT01956188.
- Efeito da suplementação de creatina, associada ou não ao treinamento de força, sobre a peroxidação lipídica em mulheres idosas(2014) ALVES, Christiano Robles Rodrigues; MEREGE FILHO, Carlos Alberto Abujabra; JANNING, Paulo Roberto; BECHARA, Luiz Roberto Grassmann; AZEVEDO, Rafael de Almeida; BENATTI, Fabiana Braga; PEREIRA, Rosa Maria Rodrigues; PINTO, Ana Lúcia de Sá; BRUM, Patrícia Chakur; GUALANO, BrunoThe aim of this study was to evaluate the effects of creatine supplementation associated or not with strength training upon lipid peroxidation in older women. This was a clinical, randomized, double-blind, placebo-controlled trial. Older women were randomly allocated into four groups: 1) placebo supplementation (PL, n = 10), 2) creatine supplementation (CR; n = 10), 3) placebo supplementation associated with strength training (PL + RT, n = 6) and 4) creatine supplementation associated with strength training (CR + RT, n = 8). Before (PRE) and after 24 weeks (POST), blood samples were collected to measure lipid hydroperoxides concentration by spectrophotometry. No statistical difference was observed on the lipid hydroperoxides concentration between groups (PL: PRE = 48.7 ± 36.9; POST = 29.3 ± 18.8; Δ = -13.0 ± 26.8; CR : PRE = 51.0 ± 46.0; POST = 54.2 ± 51.6; Δ = -8.6 ± 30.2; + PL TR: PRE = 33.0 ± 11.2; POST = 47.3 ± 31.6, Δ = 14.3 ± 39.2; CR + TR: PRE = 18.5 ± 10.1; POST = 28.1 ± 17.9, Δ = 9.7 ± 16.4 pmol.mg-1 of total protein, p = 0.17). Creatine supplementation associated or not with strength training did not affect the lipid peroxidation, an important plasmatic marker of oxidative stress, in elderly women.
- The Liposuction-Induced Effects on Adiponectin and Selected Cytokines Are Not Affected by Exercise Training in Women(2014) SOLIS, Marina Yazigi; ARTIOLI, Guilherme Giannini; MONTAG, Eduardo; PAINELLI, Vitor de Salles; SAITO, Fabio Lopes; LIMA, Fernanda Rodrigues; ROSCHEL, Hamilton; GUALANO, Bruno; LANCHA JUNIOR, Antonio Herbert; BENATTI, Fabiana BragaIt has been suggested that the abrupt liposuction-induced decrease in adipose tissue could affect adipokine secretion pattern. We hypothesized that exercise training could positively impact adipokine metabolism following liposuction. The aim of this study was to investigate the effects of liposuction on inflammation-related adipokines in women who were either exercise-trained or remained sedentary after surgery. Thirty-six healthy normal-weight women underwent an abdominal liposuction and two months after surgery were randomly allocated into two groups: trained (TR, n = 18, four-month exercise program) and nontrained (NT, n = 18). Inflammation-related adipokine serum levels (TNF-alpha, IL-6, IL-10, and adiponectin) and abdominal and thigh subcutaneous adipose tissue (scAT) mRNA levels were assessed before (PRE) and six months after surgery (POST6). TNF-alpha, IL-6, and IL-10 serum levels were unchanged in both groups. In contrast, TNF-alpha, IL-6, and IL-10 mRNA levels in scAT were increased, whereas adiponectin scAT mRNA and serum levels were decreased at POST6 (P < 0.05, main effect for time). No changes were observed in mRNA levels of MCP-1, CD14, and CD68 in any of the groups. In conclusion, liposuction downregulates adiponectin scAT gene expression and serum levels and upregulates scAT gene expression of inflammation-related genes six months after surgery in normal-weight women, irrespective of exercise training.
- Creatine Supplementation Associated or Not with Strength Training upon Emotional and Cognitive Measures in Older Women: A Randomized Double-Blind Study(2013) ALVES, Christiano Robles Rodrigues; MEREGE FILHO, Carlos Alberto Abujabra; BENATTI, Fabiana Braga; BRUCKI, Sonia; PEREIRA, Rosa Maria R.; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; ROSCHEL, Hamilton; GUALANO, BrunoPurpose: To assess the effects of creatine supplementation, associated or not with strength training, upon emotional and cognitive measures in older woman. Methods: This is a 24-week, parallel-group, double-blind, randomized, placebo-controlled trial. The individuals were randomly allocated into one of the following groups (n=14 each): 1) placebo, 2) creatine supplementation, 3) placebo associated with strength training or 4) creatine supplementation associated with strength training. According to their allocation, the participants were given creatine (4 x 5 g/d for 5 days followed by 5 g/d) or placebo (dextrose at the same dosage) and were strength trained or not. Cognitive function, assessed by a comprehensive battery of tests involving memory, selective attention, and inhibitory control, and emotional measures, assessed by the Geriatric Depression Scale, were evaluated at baseline, after 12 and 24 weeks of the intervention. Muscle strength and food intake were evaluated at baseline and after 24 weeks. Results: After the 24-week intervention, both training groups (ingesting creatine supplementation and placebo) had significant reductions on the Geriatric Depression Scale scores when compared with the non-trained placebo group (p = 0.001 and p = 0.01, respectively) and the non-trained creatine group (p < 0.001 for both comparison). However, no significant differences were observed between the non-trained placebo and creatine (p = 0.60) groups, or between the trained placebo and creatine groups (p = 0.83). Both trained groups, irrespective of creatine supplementation, had better muscle strength performance than the non-trained groups. Neither strength training nor creatine supplementation altered any parameter of cognitive performance. Food intake remained unchanged. Conclusion: Creatine supplementation did not promote any significant change in cognitive function and emotional parameters in apparently healthy older individuals. In addition, strength training per se improved emotional state and muscle strength, but not cognition, with no additive effects of creatine supplementation.
- Exercise training in childhood-onset systemic lupus erythematosus: a controlled randomized trial(2013) PRADO, Danilo M. L.; BENATTI, Fabiana B.; SA-PINTO, Ana L. de; HAYASHI, Ana P.; GUALANO, Bruno; PEREIRA, Rosa M. R.; SALLUM, Adriana M. E.; BONFA, Eloisa; SILVA, Clovis A.; ROSCHEL, HamiltonIntroduction: Exercise training has emerged as a promising therapeutic strategy to counteract physical dysfunction in adult systemic lupus erythematosus. However, no longitudinal studies have evaluated the effects of an exercise training program in childhood-onset systemic lupus erythematosus (C-SLE) patients. The objective was to evaluate the safety and the efficacy of a supervised aerobic training program in improving the cardiorespiratory capacity in C-SLE patients. Methods: Nineteen physically inactive C-SLE patients were randomly assigned into two groups: trained (TR, n = 10, supervised moderate-intensity aerobic exercise program) and non-trained (NT, n = 9). Gender-,body mass index (BMI)- and age-matched healthy children were recruited as controls (C, n = 10) for baseline (PRE) measurements only. C-SLE patients were assessed at PRE and after 12 weeks of training (POST). Main measurements included exercise tolerance and cardiorespiratory measurements in response to a maximal exercise (that is, peak VO2, chronotropic reserve (CR), and the heart rate recovery (Delta HRR) (that is, the difference between HR at peak exercise and at both the first (Delta HRR1) and second (Delta HRR2) minutes of recovery after exercise). Results: The C-SLE NT patients did not present changes in any of the cardiorespiratory parameters at POST (P > 0.05). In contrast, the exercise training program was effective in promoting significant increases in time-to-exhaustion (P = 0.01; ES = 1.07), peak speed (P = 0.01; ES = 1.08), peak VO2 (P = 0.04; ES = 0.86), CR (P = 0.06; ES = 0.83), and in Delta HRR1 and Delta HRR2 (P = 0.003; ES = 1.29 and P = 0.0008; ES = 1.36, respectively) in the C-SLE TR when compared with the NT group. Moreover, cardiorespiratory parameters were comparable between C-SLE TR patients and C subjects after the exercise training intervention, as evidenced by the ANOVA analysis (P > 0.05, TR vs. C). SLEDAI-2K scores remained stable throughout the study. Conclusion: A 3-month aerobic exercise training was safe and capable of ameliorating the cardiorespiratory capacity and the autonomic function in C-SLE patients.
- Exercise Increases Insulin Sensitivity and Skeletal Muscle AMPK Expression in Systemic Lupus Erythematosus: A Randomized Controlled Trial(2018) BENATTI, Fabiana B.; MIYAKE, Cintia N. H.; DANTAS, Wagner S.; ZAMBELLI, Vanessa O.; SHINJO, Samuel K.; PEREIRA, Rosa M. R.; SILVA, Maria Elizabeth R.; SA-PINTO, Ana Lucia; BORBA, Eduardo; BONFA, Eloisa; GUALANO, BrunoSystemic lupus erythematosus (SLE) patients may show increased insulin resistance (IR) when compared with their healthy peers. Exercise training has been shown to improve insulin sensitivity in other insulin-resistant populations, but it has never been tested in SLE. Therefore, the aim of the present study was to assess the efficacy of a moderate-intensity exercise training program on insulin sensitivity and potential underlying mechanisms in SLE patients with mild/inactive disease. A 12-week, randomized controlled trial was conducted. Nineteen SLE patients were randomly assigned into two groups: trained (SLE-TR, n = 9) and non-trained (SLE-NT, n = 10). Before and after 12 weeks of the exercise training program, patients underwent a meal test (MT), from which surrogates of insulin sensitivity and beta-cell function were determined. Muscle biopsies were performed after the MT for the assessment of total and membrane GLUT4 and proteins related to insulin signaling [ Akt and AMP-activated protein kinase (AMPK)]. SLE-TR showed, when compared with SLE-NT, significant decreases in fasting insulin [-39 vs. + 14%, p = 0.009, effect size (ES) = -1.0] and in the insulin response to MT (-23 vs. + 21%, p = 0.007, ES = -1.1), homeostasis model assessment IR (-30 vs. + 15%, p = 0.005, ES = -1.1), a tendency toward decreased proinsulin response to MT (-19 vs. + 6%, p = 0.07, ES = -0.9) and increased glucagon response to MT (+3 vs. -3%, p = 0.09, ES = 0.6), and significant increases in the Matsuda index (+66 vs. -31%, p = 0.004, ES = 0.9) and fasting glucagon (+4 vs. -8%, p = 0.03, ES = 0.7). No significant differences between SLT-TR and SLT-NT were observed in fasting glucose, glucose response to MT, and insulinogenic index (all p > 0.05). SLE-TR showed a significant increase in AMPK Thr 172 phosphorylation when compared to SLE-NT (+73 vs. -12%, p = 0.014, ES = 1.3), whereas no significant differences between groups were observed in Akt Ser 473 phosphorylation, total and membrane GLUT4 expression, and GLUT4 translocation (all p > 0.05). In conclusion, a 12-week moderate-intensity aerobic exercise training program improved insulin sensitivity in SLE patients with mild/inactive disease. This effect appears to be partially mediated by the increased insulin-stimulated skeletal muscle AMPK phosphorylation.
- A randomized controlled trial to reduce sedentary time in rheumatoid arthritis: protocol and rationale of the Take a STAND for Health study(2020) PINTO, Ana Jessica; PECANHA, Tiago; MEIRELES, Kamila; BENATTI, Fabiana Braga; BONFIGLIOLI, Karina; PINTO, Ana Lucia de Sa; LIMA, Fernanda Rodrigues; PEREIRA, Rosa Maria Rodrigues; IRIGOYEN, Maria Claudia Costa; TURNER, James Edward; KIRWAN, John P.; OWEN, Neville; DUNSTAN, David W.; ROSCHEL, Hamilton; GUALANO, BrunoBackground Patients with rheumatoid arthritis spend most of their daily hours in sedentary behavior (sitting), a predisposing factor to poor health-related outcomes and all-cause mortality. Interventions focused on reducing sedentary time could be of novel therapeutic relevance. However, studies addressing this topic remain scarce. We aim to investigate the feasibility and efficacy of a newly developed intervention focused on reducing sedentary time, and potential clinical, physiological, metabolic and molecular effects in rheumatoid arthritis. Methods The Take a STAND for Health study is a 4-month, parallel-group, randomized controlled trial, in which postmenopausal patients with rheumatoid arthritis will set individually tailored, progressive goals to replace their sedentary time with standing and light-intensity activities. Patients will be recruited from the Clinical Hospital (School of Medicine, University of Sao Paulo) and will be assessed at baseline and after a 4-month follow up. Outcomes will include objectively measured sedentary behavior (primary outcome) and physical activity levels, clinical parameters, anthropometric parameters and body composition; aerobic fitness, muscle function, blood pressure, cardiovascular autonomic function, vascular function and structure, health-related quality of life, and food intake. Blood and muscle samples will be collected for assessing potential mechanisms, through targeted and non-targeted approaches. Discussion Findings will be of scientific and clinical relevance with the potential to inform new prescriptions focused on reducing sedentary behavior, a modifiable risk factor that thus far has been overlooked in patients with rheumatoid arthritis.
- Effects of a new intervention based on the Health at Every Size approach for the management of obesity: The ""Health and Wellness in Obesity"" study(2018) ULIAN, Mariana Dimitrov; PINTO, Ana Jessica; SATO, Priscila de Morais; BENATTI, Fabiana B.; CAMPOS-FERRAZ, Patricia Lopes de; COELHO, Desire; ROBLE, Odilon J.; SABATINI, Fernanda; PEREZ, Isabel; ABURAD, Luiz; VESSONI, Andre; UNSAIN, Ramiro Fernandez; ROGERO, Marcelo Macedo; TOPORCOV, Tatiana Natasha; SA-PINTO, Ana Lucia de; GUALANO, Bruno; SCAGLIUSI, Fernanda B.Health at Every Size (R) (HAES (R)) is a weight-neutral approach focused on promoting healthy behaviors in people with different body sizes. This study examined multiple physiological, attitudinal, nutritional, and behavioral effects of a newly developed, intensive, interdisciplinary HAES (R)-based intervention in obese women. This was a prospective, seven-month, randomized (2: 1), controlled, mixed-method clinical trial. The intervention group (I-HAES (R); n = 39) took part in an intensified HAES (R)-based intervention comprising a physical activity program, nutrition counseling sessions, and philosophical workshops. The control group (CTRL; n = 19) underwent a traditional HAES (R)-based intervention. Before and after the interventions, participants were assessed for physiological, psychological, and behavioral parameters (quantitative data) and took part in focus groups (qualitative data). Body weight, body mass index, and waist and hip circumferences did not significantly differ within or between groups (P > 0.05). I-HAES (R) showed increased peak oxygen uptake and improved performance in the timed-stand test (P = 0.004 and P = 0.004, between-group comparisons). No significant within-or between-group differences were observed for objectively measured physical activity levels, even though the majority of the I-HAES (R) participants indicated that they were engaged in or had plans to include physical activity in their routines. I-HAES (R) resulted in improvements in eating attitudes and practices. The I-HAES (R) group showed significantly improved all Body Attitude Questionnaire subscale and all Figure Rating Scale scores (P <= 0.05 for all parameters, within-group comparisons), whereas the CTRL group showed slight or no changes. Both groups had significant improvements in health-related quality of life parameters, although the I-HAES (R) group had superior gains in the ""physical health,"" ""psychological health,"" and ""overall perception of quality of life and health"" (P = 0.05, 0.03, and 0.02, respectively, between-group comparisons) domains. Finally, most of the quantitative improvements were explained by qualitative data. Our results show that this new intensified HAES (R)-based intervention improved participants' eating attitudes and practices, perception of body image, physical capacity, and health-related quality of life despite the lack of changes in body weight and physical activity levels, showing that our novel approach was superior to a traditional HAES (R)-based program.
- A randomized clinical trial on the effects of exercise on muscle remodelling following bariatric surgery(2021) GIL, Saulo; KIRWAN, John P.; MURAI, Igor H.; DANTAS, Wagner S.; MEREGE-FILHO, Carlos Alberto Abujabra; GHOSH, Sujoy; SHINJO, Samuel K.; PEREIRA, Rosa M. R.; TEODORO, Walcy R.; FELAU, Sheylla M.; BENATTI, Fabiana B.; SA-PINTO, Ana L.; LIMA, Fernanda; CLEVA, Roberto; SANTO, Marco Aurelio; GUALANO, Bruno; ROSCHEL, HamiltonBackground Muscle atrophy and strength loss are common adverse outcomes following bariatric surgery. This randomized, controlled trial investigated the effects of exercise training on bariatric surgery-induced loss of muscle mass and function. Additionally, we investigated the effects of the intervention on molecular and histological mediators of muscle remodelling. Methods Eighty women with obesity were randomly assigned to a Roux-en-Y gastric bypass (RYGB: n = 40, age = 42 +/- 8 years) or RYGB plus exercise training group (RYGB + ET: n = 40, age = 38 +/- 7 years). Clinical and laboratory 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). A healthy, lean, age-matched control group was recruited to provide reference values for selected variables. Results Surgery resulted in a similar (P = 0.66) reduction in lower-limb muscle strength in RYGB and RYGB+ET (-26% vs. -31%), which was rescued to baseline values in RYGB + ET (P = 0.21 vs. baseline) but not in RYGB (P < 0.01 vs. baseline). Patients in RYGB+ET had greater absolute (214 vs. 120 kg, P < 0.01) and relative (2.4 vs. 1.4 kg/body mass, P < 0.01) muscle strength compared with RYGB alone at POST9. Exercise resulted in better performance in timed-up-and-go (6.3 vs. 7.1 s, P = 0.05) and timed-stand-test (18 vs. 14 repetitions, P < 0.01) compared with RYGB. Fat-free mass was lower (POST9-PRE) after RYBG than RYGB + ET (total: -7.9 vs. -4.9 kg, P < 0.01; lower-limb: -3.8 vs. -2.7 kg, P = 0.02). Surgery reduced Types I (similar to - 21%; P = 0.99 between-group comparison) and II fibre cross-sectional areas (similar to - 27%; P = 0.88 between-group comparison), which were rescued to baseline values in RYGB+ET (P > 0.05 vs. baseline) but not RYGB (P > 0.01 vs. baseline). RYGB + ET showed greater Type I (5187 vs. 3898 mu m(2), P < 0.01) and Type II (5165 vs. 3565 mu m(2), P < 0.01) fCSA than RYGB at POST9. RYGB + ET also resulted in increased capillarization (P < 0.01) and satellite cell content (P < 0.01) than RYGB at POST9. Gene-set normalized enrichment scores for the muscle transcriptome revealed that the ubiquitin-mediated proteolysis pathway was suppressed in RYGB + ET at POST9 vs. PRE (NES: -1.7; P < 0.01), but not in RYGB. Atrogin-1 gene expression was lower in RYGB + ET vs. RYGB at POST9 (0.18 vs. 0.71-fold change, P < 0.01). From both genotypic and phenotypic perspectives, the muscle of exercised patients resembled that of healthy lean individuals. Conclusions This study provides compelling evidence-from gene to function-that strongly supports the incorporation of exercise into the recovery algorithm for bariatric patients so as to counteract the post-surgical loss of muscle mass and function.
- Poor muscle strength and function in physically inactive childhood-onset systemic lupus erythematosus despite very mild disease(2016) PINTO, Ana Jessica; BENATTI, Fabiana Braga; ROSCHEL, Hamilton; PINTO, Ana Lucia de Sa; SILVA, Clovis Artur; SALLUM, Adriana Maluf Elias; GUALANO, BrunoObjective: To compare muscle strength (i.e. lower- and upper-body strength) and function between physically inactive childhood-onset systemic lupus erythematosus patients (C-SLE) and healthy controls (CTRL). Methods: This was a cross-sectional study and the sample consisted of 19 C-SLE (age between 9 and 18 years) and 15 CTRL matched by age, sex, body mass index (BMI), and physical activity levels (assessed by accelerometry). Lower- and upper-body strength was assessed by the one-repetition-maximum (1-RM) test. Isometric strength was assessed through a handgrip dynamometer. Muscle function was evaluated by the timed-stands test (TST) and the timed-up-and-go test (TUG). Results: When compared with CTRL, C-SLE showed lower leg-press and bench-press 1-RM (p = 0.026 and p = 0.008, respectively), and a tendency toward lower handgrip strength (p = 0.052). C-SLE showed lower TST scores (p = 0.036) and a tendency toward higher TUG scores (p = 0.070) when compared with CTRL. Conclusion: Physically inactive C-SLE patients with very mild disease showed reduced muscle strength and functionality when compared with healthy controls matched by physical activity levels. These findings suggest C-SLE patients may greatly suffer from a physically inactive lifestyle than healthy controls do. Moreover, some sub-clinical ""residual"" effect of the disease or its pharmacological treatment seems to affect C-SLE patients even with a well-controlled disease. (C) 2016 Elsevier Editora Ltda.
