Introduction: Sarcopenic obesity (SO) is characterised by the confluence of muscle deterioration and high adiposity. When non-surgical interventions prove insufficient, bariatric surgery (BS) becomes the primary approach. This study aimed to address BS effects on SO outcomes 1 year post-surgery among middle-aged women, also considering physical exercise's impact. Methods: Prospective single-centre study of 140 patients who underwent Roux-en-Y gastric bypass or sleeve gastrectomy between November 2019 and December 2022. Participants were categorised into tertiles according to SO's diagnosis and severity (group 1—patients with the most severe SO; group 2—intermediate; group 3—the least severe or without SO), calculated considering the consensus issued by ESPEN and EASO in 2022. Evaluations of clinical and biochemical parameters were conducted before and 12 months after BS, and the variation was used for comparative purposes. Body composition was assessed using bone density scans. Linear regression analysis accounted for both surgery type and baseline body mass index (BMI). Results: Before BS, SO prevalence in the overall sample was 89.3%, decreasing to 2.9% after BS. Group 1 had more body fat mass (56.9 vs 54.8 vs 50.7 kg, p < 0.001), total, trunk and leg fat at baseline and a significantly lower total skeletal muscle mass (47.2 vs 49.4 vs 51.8 kg, p < 0.001). One year post-BS, group 1 presented more weight loss (− 39.8 ± 11.4 kg, p = 0.031), BMI reduction (− 15.9 ± 4.6 kg/m2, p = 0.005) and lost more fat mass (− 32.6 vs − 30.5 vs − 27.9 kg, p = 0.005), but not total skeletal muscle mass (− 5.8 vs − 5.9 vs − 6.8 kg, p = 0.130). Remission rates for comorbidities were substantial among all groups, but more marked among patients within group 1 (type 2 diabetes mellitus 75%, hypertension 47.1% and dyslipidemia 52.8%). Engagement in physical exercise of any kind has increased post-BS (33.1% vs 79.1%). Conclusion: Despite concerns about malabsorptive mechanisms potentially worsening muscle loss, patients with the most severe SO undergoing BS lost more fat mass while experiencing the smallest reduction in total skeletal muscle mass. Remission rates for comorbidities following BS were notable among all groups. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to characterize complications, metabolic improvement, and change in ambulation status for patients with impaired mobility undergoing bariatric surgery.Material and Methods: Individuals undergoing primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) from February 2008 to December 2015 were included. Impaired mobility (WC) was defined as using a wheelchair or motorized scooter for at least part of a typical day. The WC group was propensity score matched to ambulatory patients (1:5 ratio). Comparisons were made for 30-day morbidity and mortality and 1-year improvement in weight-related comorbidities.Results: There were 93 patients in the WC group matched to 465 ambulatory controls. The median operative time (180 vs 159 min, p = 0.003) and postoperative length of stay (4 vs 3 days, p ≤ 0.001) was higher in the WC group. There were no differences in readmission or all-cause morbidity within 30 days. The median percent excess weight loss (%EWL) at 1 year was similar (WC group, 65% available, 53% EWL vs AMB group, 73% available, 54% EWL); however, patients with impaired mobility were less likely to experience improvement in diabetes (76 vs 90%, p = 0.046), hypertension (63 vs 82%, p < 0.005), and obstructive sleep apnea (53 vs 71%, p < 0.001). Within the WC group, 62% had improvement in their mobility status, eliminating dependence on wheelchair or scooter assistance.Conclusion: Patients with both obesity and impaired mobility experience similar rates of perioperative morbidity and weight loss at 1 year compared to ambulatory controls. However, improvement in weight-related comorbidities may be less likely with impaired mobility. [ABSTRACT FROM AUTHOR]

Background: It is well accepted that bariatric surgery has cardiovascular and metabolic effects independent of weight loss. Methods: Weight loss outcomes of patients undergoing Roux -en -Y gastric bypass (RYGB) at a high volume referral center were collected at 1 year postoperatively. Patients with failed primary weight loss were identified. Primary inadequate weight loss was defined as total body weight loss less than 15 %. Changes in hypertension (HTN), dyslipidemia, type 2 diabetes mellitus (T2DM), and metabolic syndrome profiles were investigated using Student's t test. Results: A total of 2500 patients underwent RYGB from the years 2001-2013 at our institution. One hundred five (4.2 %) patients had primary inadequate weight loss. Within this cohort, 81 (77.1 %) patients had hypertension, 67 (63.8 %) had dyslipidemia, 53 (50.5 %) had type 2 diabetes mellitus, and 66 (62.9 %) patients had metabolic syndrome. At 1 year postoperatively, all metabolic parameters were significantly improved. Measures of metabolic disease included high-density lipoprotein (HDL) (46.3 ± 11.6 versus 54.1 ± 12.7 mg/dL, p < 0.01), low-density lipoprotein (LDL) (103.6 ± 35.8 versus 89.2 ± 30.0 mg/dL, p < 0.01), triglycerides (177.3 ± 139.1 versus 117.6 ± 59.3 mg/dL, p < 0.01), mean plasma glucose (128.9 ± 55.3 versus 102.7 ± 27.3 mg/dL, p < 0.01), and hemoglobin AC (7.3 ± 1.9 versus 6.1 ± 1.0 %, p < 0.01). HTN was noted to improve in 27 (33.3 %) patients based on a decrease in the number of anti-hypertensives used (1.7 ± 1.0 versus 1.3 ± 1.3, p < 0.01), and 21 (31.8 %) patients had resolution of their metabolic syndrome. Conclusion: Improvement in cardiometabolic comorbidities still occurs despite suboptimal weight loss following RYGB. [ABSTRACT FROM AUTHOR]
