Abstract Background: Addressing individuals’ motivation to lose weight among patients with morbid obesity is an essential entity in weight reduction. Failures to shift motivation into weight loss actions are common. These could be contributed by the inadequacy to identify and subsequently address the key reasons, that are of particular concern to the patient' individual needs. We aimed to understand the motivations better and identify the reasons why morbidly obese patients attending hospital-based weight management programmes (WMP) wanted to lose weight. Methods: The study used a qualitative approach to analyze part of a quantitative questionnaire of a more extensive study to understand factors influencing weight loss among morbidly obese patients. We used thematic content analysis to analyze responses from a self-administered open-ended question "What is the main factor why you want to lose your weight?”. A total of 225 new patients attending obesity clinics in two tertiary hospitals responded to the questionnaire. Results: Patients’ mean BMI was 45.6±8.05 kg/m2. Four themes emerged for the reasons why morbidly obese patients wanted to lose weight. Health was the most commonly inferred theme (84%). Patients were concerned about the impact obesity had on their health. Overcoming obesity was seen as a reward not just for physical health, but also for their psychological wellbeing. Patients regard being functional to care for themselves, their family members, as well as their religious and career needs as the next most crucial theme (25.8%). Patients raised the theme appearance (12.9%), especially with regards to wanting to look and feel beautiful. The last theme was perceived stigmatization for being morbidly obese as they were mocked and laughed at for their appearance (3.1%).Conclusion: Patients with morbid obesity in this study had expressed their main personal motivational reasons to lose weight. Concerns about the impact of morbid obesity on health, physical, social and obligatory function, appearance and perceived stigma warrant detailed exploration by the managing health professionals. Identifying and addressing these unique personal motivations in a focused approach is vital at the beginning and throughout a weight reduction program in this unique group.

Abstract Context: C1q/TNF-related protein-9 (CTRP9) is a novel adipokine that has beneficial metabolic and cardiovascular effects in various animal models. Alterations in circulating CTRP9 have also been observed in patients with cardiovascular disease and diabetes, but little is known about the impact of obesity and bariatric surgery on CTRP9 concentrations. Objective: The aim of this study was to compare CTRP9 levels in obese and lean subjects and to determine whether circulating CTRP9 levels in morbidly obese patients are altered by bariatric surgery. Design, Setting, and Participants: Fifty-nine obese bariatric surgical patients and 62 lean controls were recruited to participate in a cross-sectional study at an academic medical center. The obese patients were further invited to participate in a cohort study, and 21 returned for analysis at 3 and 6 months postsurgery. Intervention: Bariatric surgery (Roux-en-Y gastric bypass and vertical sleeve gastrectomy) was the intervention for this study. Main Outcome Measures: Fasting serum was obtained from all subjects on entry to the study and was analyzed in the core laboratory for hemoglobin A1c, glucose, aspartate aminotransferase, alanine aminotransferase, total cholesterol, high- and low-density lipoprotein cholesterol, and triglycerides; CTRP9, insulin, adiponectin, and leptin were measured by ELISA. Serum from the patients in the cohort study was also analyzed at 3 and 6 months. Results: Serum CTRP9 was significantly higher in the obese group compared to the lean group. CTRP9 was associated with obesity, even after controlling for age, gender, and ethnicity. Following bariatric surgery, there was a significant decrease in weight at 3 and 6 months postprocedure, accompanied by decreases in CTRP9, hemoglobin A1c and leptin, and an increase in serum adiponectin. Conclusions: CTRP9 levels are elevated in obesity and significantly decrease following weight loss surgery. Our data suggest that CTRP9 may play a compensatory role in obesity, similar to that of insulin, and is down-regulated following weight loss surgery.

Background Obesity is associated with hypertension, but the exact mechanism is not fully understood. Bariatric surgery significantly decreases weight and blood pressure (BP). Low plasma nitric oxide (NO) and raised asymmetric dimethylarginine (ADMA), an endogenous inhibitor of NO, concentrations are associated with both obesity and hypertension. Correlations between the changes in these parameters were studied after bariatric surgery. Methods Weight, BP, plasma ADMA and NO were measured in 29 obese patients (24 female, 5 male) before and six weeks after bariatric surgery. Results Patients were 39.2 ± 1.2 (mean ± SEM) years old and weighed 126 ± 3 kg. Six weeks after the surgery, patients had lost 10 ± 0.7 kg ( P < 0.0001) and mean arterial pressure (MAP) decreased by 11 ± 1.0 mmHg ( P < 0.0001). The plasma ADMA concentration decreased by 24 ± 2% from 5 ± 0.4 to 4.0 ± 0.3 μmol/L ( P < 0.0001). The plasma total nitrite concentration increased by 15 ± 1% from 51.4 ± 2.6 to 60 ± 3 μmol/L ( P < 0.0001). The correlation between the decrease of ADMA and increase of NO subsequent to weight loss was significant ( P < 0.0001). However, MAP was not correlated to the changes in ADMA or NO. Conclusions After bariatric surgery, beneficial changes in BP, NO and ADMA occur, but our findings suggest that these BP changes are independent of changes in the NO–ADMA axis. Other causes for the changes in BP should therefore be considered.

Introduction: Laparoscopic sleeve gastrectomy is a primary treatment of obesity among older adults and its satisfactory outcomes would be the main reason behind the popularity of this procedure. We aim to evaluate the impact of age on excess weight loss in adult morbidly obese subjects older than 60 years old following LSG.Methods: In this retrospective survey, 3,072 subjects were included in the study that underwent LSG in Erfan Hospital. Screening follow-up period was 12 months. The level of statistical significance was set at P < 0.05. We hired comorbid conditions to avoid bias results including hypertension, diabetes mellitus and dyslipidemia. Results: Of 3072 patients, 1879 cases were females (61.2%) and 1193 subjects were males (38.8 %). Mean %EBMIL of the group 12 months after surgery was 78.9 %. In younger than 60 years old group, mean %EBMIL 12 months postoperative 83 % and patients  over 60 years demonstrated mean %EBMIL 74.9 %. There was an obvious difference among age groups in presence of diabetes mellitus and hypertension in the older group which was more frequent. Conclusion: To sum up, laparoscopic sleeve gastrectomy is safe procedure for older groups. Albeit, %EBMIL was significantly lower in older group compared to younger subjects, but resolution in comorbidities was satisfactory.

There is a high prevalence of vitamin-D deficiency in obese individuals that could be attributed to vitamin-D sequestration in the adipose tissue. Associations between vitamin-D deficiency and unfavorable cardiometabolic outcomes were reported. However, the pathophysiological mechanisms behind these associations are yet to be established. In our previous studies, we demonstrated microvascular dysfunction in obese adults that was associated with reduced nitric oxide (NO) production. Herein, we examined the role of vitamin D in mitigating microvascular function in morbidly obese adults before and after weight loss surgery. We obtained subcutaneous (SAT) and visceral adipose tissue (VAT) biopsies from bariatric patients at the time of surgery (n = 15) and gluteal SAT samples three months post-surgery (n = 8). Flow-induced dilation (FID) and acetylcholine-induced dilation (AChID) and NO production were measured in the AT-isolated arterioles ± NO synthase inhibitor N(ω)-nitro-L-arginine methyl ester (L-NAME), hydrogen peroxide (H2O2) inhibitor, polyethylene glycol-modified catalase (PEG-CAT), or 1,25-dihydroxyvitamin D. Vitamin D improved FID, AChID, and NO production in AT-isolated arterioles at time of surgery; these effects were abolished by L-NAME but not by PEG-CAT. Vitamin-D-mediated improvements were of a higher magnitude in VAT compared to SAT arterioles. After surgery, significant improvements in FID, AChID, NO production, and NO sensitivity were observed. Vitamin-D-induced changes were of a lower magnitude compared to those from the time of surgery. In conclusion, vitamin D improved NO-dependent arteriolar vasodilation in obese adults; this effect was more significant before surgery-induced weight loss.
