    Are Perceived Barriers to Exercise and Level of Interest in Fitness Programs Different Between Preoperative and Postoperative Bariatric Surgery Groups?
    (Liebert, 2020-12) Athanasiadis, Dimitrios; Hilgendorf, William; Kubicki, Natalia; Banerjee, Ambar; Surgery, School of Medicine
    Background: Exercise following bariatric surgery is associated with better outcomes. We aimed to assess the level of interest in fitness programs, self-reported exercise duration, and perceived obstacles for exercising in bariatric patients. Materials and Methods: All patients who presented to our hospital for any bariatric clinic visit were administered a questionnaire, which explored their interest in a free 10-min DVD-based workout (DW) versus an internet-based workout (IW), average duration of exercise per week, and two perceived obstacles to exercise. Results: One hundred fifty-nine preoperative and 135 postoperative patients were surveyed. Overall, there was more interest in DW than in IW. The mean duration of exercise in the preop group was 89 ± 92.1 min/week, whereas the postop group reported 84.4 ± 103.7 min/week (p = 0.717). Time was the most frequent obstacle in both groups, whereas orthopedic discomfort was reported less frequently in the postoperative compared with the preoperative population (7% vs. 18.1%, respectively, p = 0.001). Conclusions: Despite the postoperative group reporting less orthopedic pain, mean exercise time per week was the same as the preoperative group. Time constraints were the most frequently reported barrier in both groups, suggesting a pathway for intervention.

    (Elsevier, 2018-08) Hilgendorf, William; Butler, Annabelle; Timsina, Lava; Choi, Jennifer; Banerjee, Ambar; Selzer, Don; Stefanidis, Dimitrios; Pediatrics, School of Medicine
    Background Bariatric surgery represents the most effective intervention for severe obesity available today; however, significant variability in postoperative outcomes exists. Effective tools that predict postoperative outcomes are needed for decision-making and patient counseling. Objectives We hypothesized that a validated behavioral assessment tool, the Cleveland Clinic Behavioral Rating Scale (CCBRS), would predict excess weight loss, health-related quality of life, depression, anxiety, and alcohol use after bariatric surgery. Setting Hospital in the United States. Methods A prospective observational study with 2-year planned follow-up was conducted with patients who completed a psychological clinical interview, the Short Form 36 (SF-36) v.2 Health Survey and brief self-report questionnaires measuring depression (PHQ-9), anxiety (GAD-7), and alcohol use (AUDIT) preoperatively. At the conclusion of the preoperative psychological evaluation, the psychologist completed the CCBRS. All questionnaires were readministered at 6, 12, 18, and 24 months after surgery. Generalized estimating equations were used to assess whether any CCBRS ratings predicted surgery outcomes. Results One hundred seventy-nine patients (113 Roux-en-Y gastric bypass and 66 sleeve gastrectomy) were included in the analyses. SF-36 scores, PHQ-9 scores, and the AUDIT total scores improved significantly after surgery, while GAD-7 scores did not change appreciably. Higher preoperative CCBRS ratings predicted higher SF-36 scores, and lower PHQ-9, GAD-7 and AUDIT scores. The CCBRS social support rating predicted higher postoperative percent excess weight loss. Conclusion A behavioral rating scale (CCBRS) completed before bariatric surgery predicted postoperative weight loss, quality of life, depression, and anxiety. Therefore, this tool may prove useful in patient counseling and expectation management before surgery.

    Can a brief assessment of social support predict outcomes after bariatric surgery?
    (Wiley, 2021-02) Hilgendorf, William; Monfared, Sara; Hassan Beygi Monfared, Sina; Athanasiadis, Dimitrios I.; Selzer, Don; Choi, Jennifer N.; Banerjee, Ambar; Stefanidis, Dimitrios; Surgery, School of Medicine
    Social support is important to optimize bariatric surgery outcomes, but limited tools exist for brief and effective assessment preoperatively. The aims of the study were to determine the extent to which two ratings of social support can predict bariatric surgery outcomes, and to examine any associations between these two methods.In this retrospective study, patients were included for whom the Cleveland clinic behavioral rating system (CCBRS) and Flanagan quality of life scale (FQoLS) scores were obtained as part of their preoperative psychosocial evaluation. They were followed up for 6 to 24 months after bariatric surgery. Linear and logistic regressions were performed with patients' CCBRS and FQoLS scores as independent variables, and percent excess weight loss (%EWL), length of stay (LOS), complications, readmissions and loss to follow-up as dependent variables. The prediction of CCBRS ratings from FQoLS social support items was also evaluated. A total of 415 patients were included in the analysis. There were significant associations between the CCBRS and three of the four relevant FQoLS self-ratings. As CCBRS and FQoLS scores increased, complications decreased significantly. The CCBRS alone additionally predicted decreased length of hospital stay and approached significance for predicting decreased readmission rates. There were no associations between %EWL and behavior ratings. The degree of patients' social support is associated with important bariatric surgery outcomes. It is possible to obtain this valuable information via the administration of brief assessments prior to bariatric surgery.

    High Rates of Nicotine Use Relapse and Ulcer Development Following Roux-en-Y Gastric Bypass
    (Springer, 2021-02) Athanasiadis, Dimitrios I.; Christodoulides, Alexei; Monfared, Sara; Hilgendorf, William; Embry, Marisa; Stefanidis, Dimitrios; Surgery, School of Medicine
    PURPOSE: Given that smoking is known to contribute to gastrojejunal anastomotic (GJA) ulcers, cessation is recommended prior to laparoscopic Roux-en-Y gastric bypass (LRYGB). However, smoking relapse rates and the exact ulcer risk remain unknown. This study aimed to define smoking relapse, risk of GJA ulceration, and complications after LRYGB. MATERIALS AND METHODS: We performed a retrospective cohort study of patients who underwent primary LRYGB during 2011-2015. Initially, three patient categories were identified: lifetime non-smokers, patients who were smoking during the initial visit at the bariatric clinic or within the prior year (recent smokers), and patients who had ceased smoking more than a year prior to their initial clinic visit (former smokers). Smoking relapse, GJA ulcer occurrences, reinterventions, and reoperations were recorded and compared. RESULTS: A total of 766 patients were included in the analysis. After surgery, 53 (64.6%) recent smokers had resumed smoking. Out of these relapsed smokers, 51% developed GJA ulcers compared with 14.8% in non-relapsed recent smokers, 16.1% in former smokers, and 6% in lifetime nonsmokers (p < 0.001). Furthermore, relapsed smokers required more frequently endoscopic reinterventions (60.4%) compared with non-relapsed smokers (20.8%, p < 0.001), former smokers (20.7%, p < 0.001), and lifetime non-smokers (15.4%, p < 0.001). Additionally, relapsed smokers required a reoperation (18.9%) more often than non-relapsed recent smokers (5.7%, p < 0.001) and lifetime non-smokers (1.3%, p < 0.001). CONCLUSION: Smokers relapse frequently after LRYGB, and the majority experience GJA complications. They should be counseled about this risk preoperatively and directed towards less ulcerogenic procedures when possible. Alternatively, longer periods of preoperative smoking abstinence might be needed.

    How are Bariatric Patients Coping During the COVID-19 Pandemic? Analysis of Factors Known to Cause Weight Regain Among Postoperative Bariatric Patients
    (Elsevier, 2020) Athanasiadis, Dimitrios I.; Hernandez, Edward; Hilgendorf, William; Roper, Alexandra; Embry, Marisa; Selzer, Don; Stefanidis, Dimitrios; Surgery, School of Medicine
    Background The global coronavirus disease 2019 (COVID-19) pandemic is wreaking havoc on society. Bariatric patients are more prone to severe infection due to their high body mass index (BMI) and are more vulnerable to the effects of isolation, such as depression or disruption of their health habits. Objectives To quantify the impact of self-quarantine on bariatric patients and self-quarantine’s relationship with weight gain. Setting Academic hospital, United States. Methods A 30-item survey examining several known contributors to weight regain was distributed among the postoperative bariatric patients of our clinic. Changes in eating habits, exercise, depression, social support, loneliness, and anxiety were studied, among others. Results A total of 208 patients completed the survey (29.3% response rate). A large percentage of patients reported increases in their depression (44.2%), loneliness (36.2%), nervousness (54.7%), snacking (62.6%), loss of control when eating (48.2%), and binge eating (19.5%) and decreases in their social support (23.2%), healthy food eating (45.5%), and activity (55.2%). Difficulty in accessing vitamins was reported by 13%. Patients more than 18 months out of surgery regained more than 2 kg during an average of 47 days. Risk factors for weight regain were found to be loss of control when eating, increases in snacking and binge eating, reduced consumption of healthy food, and reduced physical activity. Conclusion Bariatric patients are negatively affected by the COVID-19 pandemic and subsequent social isolation on many levels. This patient population is vulnerable to crisis situations; thus, additional intervention is needed to address behaviors that lead to weight regain.

    Social support provided to bariatric surgery patients through a facebook group may improve weight loss outcomes
    (Springer, 2022) Athanasiadis, Dimitrios I.; Carr, Rosalie A.; Smith, Craig; Dirks, Rebecca C.; Hilgendorf, William; Stefanidou, Maria Nefeli; Selzer, Don; Stefanidis, Dimitrios; Surgery, School of Medicine
    Background: Patients' social support has been shown to impact outcomes after bariatric surgery. We have previously shown that a Facebook group administered by bariatric providers offers an effective alternative social support mechanism to in-person support groups, with higher patient participation. Our aim was to determine whether participation in this Facebook group could improve patient outcomes after bariatric surgery. Methods: After institutional board approval, our center's Facebook group members were electronically surveyed about their perceived value of group participation and their Facebook group usage frequency. We also collected patient age, sex, insurance, preoperative weight, type of procedure, hospital stay, postoperative complications, and weight loss from the electronic medical record. To assess the impact of Facebook group participation we compared patient outcomes between "frequent users" (those checking the Facebook group's activity at least once a week), "infrequent users", and a control group of all patients operated on during the year prior to the establishment of the Facebook group. The groups were compared after adjusting for potential confounding factors. Results: 250 out of 1400 Facebook group patients responded to the survey (18%). 195 patients were frequent and 55 were infrequent users. Outcomes were compared with 211 control patients. The groups did not differ in their baseline characteristics apart from their sex. Frequent users had a higher weight loss compared to the other groups up to 2 years postoperatively but no difference in the overall complications. On multivariable analysis, frequency of Facebook use was the main factor associated with 0.5-, 1-, and 2-year weight loss. Conclusion: Frequent participation in a Facebook support group after bariatric surgery was associated with improved early weight loss outcomes. If additional longer-term studies confirm our findings, offering similar social support groups may become essential after bariatric surgery, especially during times of social isolation when in-person social support meetings may not be feasible.
