- Exercise Mitigates Bone Loss in Women With Severe Obesity After Roux-en-Y Gastric Bypass: A Randomized Controlled Trial(2019) MURAI, Igor H.; ROSCHEL, Hamilton; DANTAS, Wagner S.; GIL, Saulo; MEREGE-FILHO, Carlos; CLEVA, Roberto de; SA-PINTO, Ana L. De; LIMA, Fernanda; SANTO, Marco A.; BENATTI, Fabiana B.; KIRWAN, John P.; PEREIRA, Rosa M.; GUALANO, BrunoContext: Bone loss after bariatric surgery potentially could be mitigated by exercise. Objective: To investigate the role of exercise training (ET) in attenuating bariatric surgery-induced bone loss. Design: Randomized, controlled trial. Setting: Referral center for bariatric surgery. Patients: Seventy women with severe obesity, aged 25 to 55 years, who underwent Roux-en-Y gastric bypass (RYGB). Intervention: Supervised, 6-month, ET program after RYGB vs. standard of care (RYGB only). Outcomes: Areal bone mineral density (aBMD) was the primary outcome. Bone microarchitecture, bone turnover, and biochemical markers were secondary outcomes. Results: Surgery significantly decreased femoral neck, total hip, distal radius, and whole body aBMD (P < 0.001); and increased bone turnover markers, including collagen type I C-telopeptide (CTX), procollagen type I N-propeptide (P1NP), sclerostin, and osteopontin (P < 0.05). Compared with RYGB only, exercise mitigated the percent loss of aBMD at femoral neck [estimated mean difference (EMD), -2.91%; P = 0.007;], total hip (EMD, -2.26%; P = 0.009), distal radius (EMD, -1.87%; P = 0.038), and cortical volumetric bone mineral density at distal radius (EMD, -2.09%; P = 0.024). Exercise also attenuated CTX (EMD, -0.20 ng/mL; P = 0.002), P1 NP (EMD, -17.59 ng/mL; P = 0.024), and sclerostin levels (EMD, -610 pg/mL; P = 0.046) in comparison with RYGB. Exercise did not affect biochemical markers (e.g., 25(OH)D, calcium, intact PTH, phosphorus, and magnesium). Conclusion: Exercise mitigated bariatric surgery-induced bone loss, possibly through mechanisms involving suppression in bone turnover and sclerostin. Exercise should be incorporated in postsurgery care to preserve bone mass.
- Acute cardiometabolic effects of brief active breaks in sitting for patients with rheumatoid arthritis(2021) PINTO, Ana J.; MEIRELES, Kamila; PECANHA, Tiago; MAZZOLANI, Bruna C.; I, Fabiana Smaira; REZENDE, Diego; BENATTI, Fabiana B.; RIBEIRO, Ana C. M.; PINTO, Ana L. S.; LIMA, Fernanda R.; SHINJO, Samuel K.; DANTAS, Wagner S.; MELLETT, Natalie A.; MEIKLE, Peter J.; OWEN, Neville; DUNSTAN, David W.; ROSCHEL, Hamilton; GUALANO, BrunoExercise is a treatment in rheumatoid arthritis, but participation in moderate-to-vigorous exercise is challenging for some patients. Light-intensity breaks in sitting could be a promising alternative. We compared the acute effects of active breaks in sitting with those of moderate-to-vigorous exercise on cardiometabolic risk markers in patients with rheumatoid arthritis. In a crossover fashion, 15 women with rheumatoid arthritis underwent three 8-h experimental conditions: prolonged sitting (SIT), 30-min bout of moderate-to-vigorous exercise followed by prolonged sitting (EX), and 3-min bouts of light-intensity walking every 30 min of sitting (BR). Postprandial glucose, insulin, c-peptide, triglycerides, cytokines, lipid classes/subclasses (lipidomics), and blood pressure responses were assessed. Muscle biopsies were collected following each session to assess targeted proteins/genes. Glucose [-28% in area under the curve (AUC), P = 0.036], insulin (-28% in AUC, P = 0.016), and c-peptide (-27% in AUC, P = 0.006) postprandial responses were attenuated in BR versus SIT, whereas only c-peptide was lower in EX versus SIT (-20% in AUC, P = 0.002). IL-1 beta decreased during BR, but increased during EX and SIT (P = 0.027 and P = 0.085, respectively). IL-1ra was increased during EX versus BR (P = 0.002). TNF-alpha concentrations decreased during BR versus EX (P = 0.022). EX, but not BR, reduced systolic blood pressure (P = 0.013). Lipidomic analysis showed that 7 of 36 lipid classes/subclasses were significantly different between conditions, with greater changes being observed in EX. No differences were observed for protein/gene expression. Brief active breaks in sitting can offset markers of cardiometabolic disturbance, which may be particularly useful for patients who may find it difficult to adhere to exercise. NEW & NOTEWORTHY Exercise is a treatment in rheumatoid arthritis but is challenging for some patients. Light-intensity breaks in sitting could be a promising alternative. Our findings show beneficial, but differential, cardiometabolic effects of active breaks in sitting and exercise in patients with rheumatoid arthritis. Breaks in sitting mainly improved glycemic and inflammatory markers, whereas exercise improved lipidomic and hypotensive responses. Breaks in sitting show promise in offsetting aspects of cardiometabolic disturbance associated with prolonged sitting in rheumatoid arthritis.
- Effects of health at every size (R) interventions on health-related outcomes of people with overweight and obesity: a systematic review(2018) ULIAN, M. D.; ABURAD, L.; OLIVEIRA, M. S. da Silva; POPPE, A. C. M.; SABATINI, F.; PEREZ, I.; GUALANO, B.; BENATTI, F. B.; PINTO, A. J.; ROBLE, O. J.; VESSONI, A.; SATO, P. de Morais; UNSAIN, R. F.; SCAGLIUSI, F. BaezaContext The growing use of interventions based on the Health at Every Size (R) (HAES (R)) in obesity management. Objective This study aimed to summarize the health-related effects of HAES (R)-based interventions on people with overweight and obesity. Data sources MEDLINE (via PubMed), EMBASE, Cochrane Library, LILACS, Google Scholar, OpenGrey and Grey Literature Report. Study selection A systematic review of studies published until January 2017 reporting on HAES (R)-based randomized and non-randomized controlled trials in people with overweight and/or obesity. Data extraction Fourteen papers met the inclusion criteria. The assessed studies included the following tests: blood profile, blood pressure, anthropometry, eating behaviour, energy intake, diet quality, psychological and qualitative evaluations. Results The HAES (R) interventions benefited both the psychological and physical activity outcomes, besides promoting behavioural and qualitative changes in eating habits. On the other hand, the results regarding cardiovascular responses, body-image perception and total energy intake were inconsistent. Conclusions Despite improving the cardiovascular status, eating behaviours, quality of life and psychological well-being in participants, other large long-term clinical trials should be performed to establish the effectiveness of HAES (R)-based interventions in improving health for people with overweight and obesity.
- 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.
- The effect of frequency of activity interruptions in prolonged sitting on postprandial glucose metabolism: A randomized crossover trial(2019) THORSEN, Ida K.; JOHANSEN, Mette Y.; PILMARK, Nanna S.; JESPERSEN, Naja Z.; BRINKLOV, Cecilie F.; BENATTI, Fabiana B.; DUNSTAN, David W.; KARSTOFT, Kristian; PEDERSEN, Bente K.; RIED-LARSEN, MathiasObjective: The primary objective was to test the hypothesis that increased frequency of interruptions in prolonged sitting reduces postprandial glycemia independent of energy intake and expenditure. Materials/Methods: Healthy, sedentary, centrally obese men (n = 14; age*, 28.2 (23.4; 38.3) years; BMI, 31.9 +/- 6.7 kg/m 2 ; VO(2)max*, 39.5 (38.8; 40.9) ml/min/kg; HbA1c, 53 +/- 0.4% (34.1 +/- 42 mmol/mol); mean +/- SD (*median (25th; 75th percentile)) completed four 8-h interventions in randomized order: 1) uninterrupted sitting (SIT), 2) sitting interrupted by 2 min of walking (-30% of VO2max) every 20th minute (INT20), 3) sitting interrupted by 6 min of walking every hour (INT60), and 4) sitting interrupted by 12 min of walking every second hour (INT120). A standardized test drink was served at the beginning of and 4 h into the intervention (total of 2310 +/- 247 kcal; 50% energy from carbohydrate, 50% energy from fat). Outcomes induded the difference in the 8-h total area under the curve (tAUC) for primarily plasma glucose, and secondarily plasma insulin and C-peptide during INT20, INT60, and INT120 compared to SIT. Results: No difference [95% CI] was observed in the primary outcome, the 8-h tAUC for the plasma glucose, during INT20, INT60, and INT120 compared to SIT ( -65.3 mmol/I*min [ - 256.3 ; 125.7], +53.8 mmol/l*min [ - 143.1; 250.8], and +18.6 mmol/l*min [-172.4; 209.6], respectively). Conclusions: Interrupting sitting with increasing frequency did not reduce the postprandial plasma glucose response to prolonged sitting in healthy, sedentary, centrally obese men.
