Lytvyak E, Zarrinpar A, Ore CD, Lee E, Yazdani-Boset K, Horgan S, Grunvald E. Stronger control of eating 3 months after sleeve gastrectomy predicts successful weight loss outcomes at one year. OBESITY PILLARS 2024; 11:100111. [PMID: 38770521 PMCID: PMC11103426 DOI: 10.1016/j.obpill.2024.100111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 05/01/2024] [Accepted: 05/02/2024] [Indexed: 05/22/2024]
Abstract
Background Weight loss response to sleeve gastrectomy (SG) is variable and predicting the effectiveness of surgery is challenging and elusive. The aim of our study was to assess and quantify the association between eating control and weight loss outcomes and identify the control of eating (CoE) attributes during the early postoperative period that might predict good vs. poor response to SG at one year. Methods A prospective longitudinal cohort study using the Control of Eating Questionnaire (CoEQ) was designed as a series before and at 3-, 6-, and 12-months post-SG. Primary outcomes were changes in CoE attributes and percent of total weight loss (%TWL) 12-months post-surgery. Subjects were categorized based on %TWL as good (GR, ≥25 %) or poor responders (PR, <25 %). A receiver operating characteristic and logistic regression analyses were performed. Results We included 41 participants (80.5% females, 51.2% Hispanic, mean age 41.7±10.6, median baseline body mass index (BMI) 43.6 kg/m2 [range 35.2-66.3]) who completed the CoEQ at all four timepoints. The "Difficulty to control eating" score at 3 months revealed the highest area under the curve (AUC) (AUC 0.711; 95%CI 0.524-0.898; p=0.032). In a trade-off between a high Youden index and high sensitivity, the "Difficulty to control eating" score of 7 at 3 months was identified as the optimal cut-off for distinguishing between GRs and PRs. Score ≤7 at 3 months was strongly independently associated with a successful weight loss target of 25%TWL at one-year post-SG (Relative Risk 4.43; 95%CI 1.06-18.54; p=0.042). Conclusion "Difficulty to control eating" score at 3 months post-SG is an independent early predictor of optimal response (achieving a successful TWL target of ≥25 % at one-year post-SG). Our results support the utility of this easy-to-administer validated tool for predicting the effectiveness of SG and may assist in identifying individuals with suboptimal response early and helping them with interventions to attain optimal weight loss targets.

Abstract
BACKGROUND Obesity is a risk factor for left ventricular hypertrophy (LVH) and diastolic dysfunction. Available evidence on impaired myocardial deformation in obese patients without apparent systolic dysfunction assessed by LV ejection fraction (LVEF) is based on single studies. The aim of the present meta-analysis was to provide a comprehensive and updated information on this issue. METHODS The PubMed, OVID-MEDLINE, and Cochrane library databases were analysed to search English-language articles published from the inception up to 31 December 2023. Studies were identified by using MeSH terms and crossing the following search items: ' myocardial strain', 'left ventricular mechanics', 'longitudinal global strain', 'speckle tracking echocardiography', 'systolic dysfunction', 'left ventricular ejection fraction', and 'obesity'. RESULTS Twenty-four studies including 5792 obese and 5518 nonobese individuals from different clinical settings were considered for the analysis. LV global longitudinal strain (GLS) was significantly impaired in the obese group [standard means difference (SMD): -0.86 ± 0.08; confidence interval (CI) -1.02 to -0.69, P < 0.0001] and this was paralleled by a significant difference in pooled LVEF between obese and controls (SMD -0.27 ± 0.06; CI -0.40 to -0.15, P < 0.0001). Unlike GLS, however, the majority of the selected studies failed to show statistically significant differences in LVEF. Furthermore, in patients with advanced obesity (BMI > 35 kg/m 2 , data from six studies), LV systolic dysfunction was more significantly detected by GLS (SMD -1.24 ± 0.19, CI -1.61/-0.87, P < 0.0001) than by LVEF (SMD -0.54 ± 0.27, CI -1.07 to -0.01, P = 0.046). CONCLUSION The present meta-analysis suggests that GLS may unmask systolic dysfunction often undetected by conventional LVEF in the obese setting; thus, this parameter should be incorporated into routine work-up aimed to identify obesity-mediated subclinical cardiac damage.

Abstract
Introduction Moderate-to-high physical activity participation is associated with a reduced risk of infertility. Yet, exercise interventions that target cardiorespiratory fitness, independent of weight loss, are lacking in obesity and female fertility research. Purpose The primary objective of the PRO-FIT-CARE (PROmoting FITness for CArdiometabolic & REproductive Health) study was to assess the feasibility of a moderate-to-high-intensity online exercise program for persons with obesity and female infertility. Methods Feasibility, safety, acceptability, and efficacy were assessed by examining: (1) recruitment and consent rate, (2) study retention, (3) adverse events, (4) participant satisfaction, (5) adherence, and (6) cardiorespiratory fitness. Results Eleven of thirty-two women contacted agreed to participate in the program (34.4% consent rate). Eight participants (72.7%) completed the study. One musculoskeletal injury was reported. There was a 30% adherence rate based on prescribed exercise intensity (60%-80% of heart rate maximum). One of eleven participants attended 80% of the exercise intervention. Based on a weekly satisfaction survey, the program had an overall high level of satisfaction. Compared to sex and age normative data, post-intervention, two of eight participants improved their cardiorespiratory fitness percentile rank. Conclusion The study highlights challenges with adherence to an online exercise program. While the program was safe and participants reported high levels of program satisfaction, approaches to improve adherence must be incorporated.

Abstract
AIMS To identify and better understand themes related to why people living with obesity (PwO) in Canada may not use professional support and to explore potential strategies to address the challenges. METHODS One-on-one interviews and online surveys, informed by the Theoretical Domains Framework, were conducted. A total of 20 PwO were interviewed and a separate group of 200 PwO were surveyed. Results from the interviews guided the development of the survey. Spearman's correlation analysis was performed to investigate the association between the theme domain scores of the PwO and their prior experience with obesity management strategies. RESULTS The 200 PwO surveyed provided representation across Canada and were diverse in age, background and gender. The most prominent domains associated with use of professional support by PwO were: Intention (rs = -0.25; p < 0.01); Social/Professional Role and Identity (rs = -0.15; p < 0.05); and Optimism (rs = -0.15; p < 0.05). For example, PwO without professional support less often reported being transparent in obesity discussions, perceived obesity to be part of their identity, and expected to manage the illness long term. Many PwO hesitated to use various adjunctive therapies due to concerns about affordability, long-term effectiveness, and side effects. CONCLUSION This study identified contextual, perception and resource considerations that contribute to healthcare decision-making and the use by PwO of professional support to manage obesity, and highlighted key areas to target with interventions to facilitate obesity management. Strategies such as consistent access to healthcare support and educational resources, as well as improved financial support may help PwO to feel more comfortable with exploring new strategies and take control of their healthcare.

Abstract
BACKGROUND Asthma is a common respiratory illness affecting 2.8 million Canadians, including 9.7% of Albertans. Prior studies showed a substantial decrease in ED visits for asthma in the decade preceding 2010, followed by a stabilization. This was attributed to improvements in the pharmacologic and non-pharmacologic treatments for asthma during that period followed by a balance between epidemiologic drivers and protective factors in the population. METHODS We assessed whether this trend continued in Alberta from 2010 to 2022 using population level data for the volume of daily ED visits, acuity of asthma exacerbations in the ED, and hospitalization rate. RESULTS The mean number of ED visits decreased from 4.5 to 2.2 per million persons per day, but the acuity of exacerbations and the proportion requiring hospitalization increased. The number of patients presenting with the highest level of acuity increased by over 300%, and the percentage of patients requiring hospitalization increased from 6.8 to 11.3%. CONCLUSION Total ED visits for asthma exacerbations continues to decline in Alberta. The reasons for an increase in more severe exacerbations requires further attention.

Abstract
Objective Full meal replacement (FMR) Intensive Lifestyle Interventions (ILI) have been used for weight management. However, predictors of efficacy with these programs are less clear. The primary objective was to assess weight loss predictors in a community-based FMR ILI program. A secondary objective was to determine if weight loss was different between virtual and in person ILI. Methods This was a retrospective cohort study involving 234 patients who started the program between 1 January 2016 and 3 March 2021. In the 24-week program, patients spent 12 weeks on FMR and then transitioned back to food for the remainder, with weekly follow up with a physician and group sessions with a dietitian. Visits were in person prior to March 2020 and virtual afterward. Results Patients' average age was 47.5 years (SD = 12.0) and 73.5% were female. Average weight loss was 14.3% (SD = 6.2%). There was no significant difference in weight loss between virtual and in person programs. Patients on a Glucagon-like Peptide-1 Receptor Agonist prior lost less weight. Other significant associations between groups were baseline Hemoglobin A1C, classes attended, as well as the age since peak weight. Conclusion Weight loss from virtual ILI was not significantly different from person ILI. More research is needed to determine how to best stratify care as virtual or in person using FMR programs.

Abstract
BACKGROUND Obstructive Sleep Apnea Syndrome (OSAS), which significantly impairs nighttime sleep quality and causes excessive daytime sleepiness, not only reduces the quality of life of patients, but also increases the social and socioeconomic burden. Wearable-noninvasive devices can provide faster OSAS screening and follow-up. Smartwatches as an objective, non-invasive, practical and relatively inexpensive method, they are attractive candidates for pre-evaluation of OSAS and referral to a physician. In this study, it was aimed to evaluate the effectiveness of a smart watch in detecting OSAS findings compared to the gold standard polysomnograhy (PSG). METHODS PSG data of the study group were compared with data such as SpO2, heart rate and saturation obtained by smartwatch from both sides, and the Cohen's kappa was used to measure for two methods and predictive values were evaluated. RESULTS A total of 115 participants [44 female (38.3%), mean age (SD): 49.24 (11.39)] were enrolled. 75 (65.22%) of the participants were diagnosed with OSAS, of which 29 (25.22%) participants have severe OSAS. The smartwatch showed good sensitivity (75% to 96%), specificity (79% to 91%), and diagnostic accuracy (AUC: 0.84 to 0.93) in predicting apnea and severe apnea, respectively. The highest agreement between PSG and smartwatch and the diagnostic ability of smartwatch were found in persons with severe OSAS. CONCLUSION The high PPV-NPV values in our study and the good compatibility coefficient of the smart watch with the PSG device can contribute to the expansion of the usage areas of smart watches that come into the lives of many people in daily practice.

Bariatric Surgery for Adults With Class I Obesity and Difficult-to-Manage Type 2 Diabetes: A Health Technology Assessment. ONTARIO HEALTH TECHNOLOGY ASSESSMENT SERIES 2023; 23:1-151.

Abstract
Background Many individuals with type 2 diabetes are classified as either overweight or obese. A patient may be described as having difficult-to-manage type 2 diabetes if their HbA1c levels remain above recommended target levels, despite efforts to treat it with lifestyle changes and pharmacotherapy. Bariatric surgery refers to procedures that modify the gastrointestinal tract. In patients with class II or III obesity, bariatric surgery has resulted in substantial weight loss, improved quality of life, reduced mortality risk, and resolution of type 2 diabetes. There is some evidence suggesting these outcomes may also be possible for patients with class I obesity as well. We conducted a health technology assessment of bariatric surgery for adults with class I obesity and difficult-to-manage type 2 diabetes, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding bariatric surgery, and patient preferences and values. Methods We performed a systematic clinical literature review. We assessed the risk of bias of each included study, using the Cochrane Risk of Bias tool for randomized controlled trials, the Risk of Bias in Non-randomized Studies - of Interventions (ROBINS-I) tool for cohort studies, and the Risk of Bias in Systematic Reviews (ROBIS) tool for systematic reviews; we assessed the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic economic literature review and conducted a cost-utility analysis of bariatric surgery in comparison with nonsurgical usual care over a lifetime horizon from a public payer perspective. We also analyzed the budget impact of publicly funding bariatric surgery for adults with class I obesity and difficult-to-manage type 2 diabetes in Ontario. To contextualize the potential value of bariatric surgery, we spoke with people with obesity and type 2 diabetes who had undergone or were considering this procedure. Results We included 14 studies in the clinical evidence review. There were large increases in diabetes remission rates (GRADE: Low to Very low) and large reductions in body mass index (GRADE: Low to Very low) with bariatric surgery than with medical management. Bariatric surgery may also reduce the use of medications for type 2 diabetes (GRADE: Low) and may improve quality of life for people with class I obesity and difficult-to-manage type 2 diabetes compared with medical management. (GRADE: Low)Our economic evidence review included 5 cost-effectiveness studies; none were conducted in a Canadian setting, and 4 were considered partially applicable to our research question. Most studies found bariatric surgery to be cost-effective compared to standard care for patients with class I obesity and type 2 diabetes; however, the applicability of these results to the Ontario context is uncertain due to potential differences in clinical practice, resource utilization, and unit costs.Our primary economic evaluation found that over a lifetime horizon, bariatric surgery was more costly (incremental cost: $8,151 per person) but also more effective than current usual care (led to a 0.339 quality-adjusted life-year [QALY] gain per person). The cost increase was driven by costs associated with surgery (before, after, and during surgery), and the QALY gain was due to life-years gained. Results were sensitive to the bariatric surgery cost and assumptions regarding its long-term benefits with respect to weight loss and diabetes remission.Publicly funding 50 bariatric surgeries in year 1, and gradually increasing to 250 surgeries in year 5, for people with class I obesity and difficult-to-manage type 2 diabetes would lead to budget increases of $0.55 million in year 1 to $2.45 million in year 5, for a total of $7.63 million over 5 years.The people with obesity and type 2 diabetes with whom we spoke reported that bariatric surgery was generally seen as a positive treatment option, and those who had undergone the procedure reported positively on its value as a treatment to manage their weight and diabetes. Conclusions For adults with class I obesity and difficult-to-manage type 2 diabetes, bariatric surgery may be more clinically effective and cost-effective than medical management. Compared with medical management in people with class I obesity and difficult-to-manage type 2 diabetes, bariatric surgery may result in large increases in diabetes remission rates, large reductions in BMI, and reduced medication use for type 2 diabetes, improved quality of life. Over a lifetime horizon, bariatric surgery led to a cost increase and QALY gain. Bariatric surgery can result in postsurgical complications that are not faced by those receiving medical management. The cost-effectiveness of bariatric surgery depends on its long-term impacts on obesity-related and diabetes-related complications, which could be uncertain.Our budget impact analysis suggests that publicly funding bariatric surgery in Ontario for people with class I obesity and difficult-to-manage type 2 diabetes would lead to a budget increase of $7.63 million over 5 years.For people with obesity and type 2 diabetes, bariatric surgery was seen as a potential positive treatment option to manage their weight and diabetes.

Abstract
BACKGROUND Migrants often face worse health outcomes in countries of transit and destination because of challenges such as financial constraints, employment problems, lack of a network of social support, language and cultural differences, and difficulties accessing health services. As understanding how the migrant context affects patient-provider engagement is critical to the provision of contextually appropriate care, this study aimed at understanding primary health care provider perspectives on challenges and opportunities of the intercultural care process for migrant patients with diabetes and obesity. METHODS This qualitative study within a multimethod, participatory research project involved primary care providers in clinics and primary care networks in Edmonton, Alberta, between September 2019 and February 2020. We explored health care providers' approaches to diabetes and obesity management, and experiences of and challenges with intercultural care. We conducted a thematic analysis using an interpretive qualitative approach. RESULTS We conducted 9 interviews and 4 focus groups and identified 3 themes: a shift from traditional weight loss-centred approaches; relationships and navigating cultural distance; and importance of and limitations in identifying and addressing root causes and barriers. Health care providers encounter considerable nonmedical challenges when supporting immigrant patients, such as navigating cultural distance and working with patients' financial constraints. INTERPRETATION The nonmedical challenges we identified can hinder the process of chronic disease management. Thus, in addition to educational programs and trainings to enhance the cultural competency of health care providers, incorporating avenues for cultural brokering in health care can provide invaluable support in patient-provider engagements to mitigate these challenges.

Temporal and Regional Trends in Obstructive Sleep Apnea Using Administrative Health Data in Alberta, Canada. Ann Am Thorac Soc 2023; 20:433-439. [PMID: 36516070 DOI: 10.1513/annalsats.202209-789oc] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/15/2022] Open
Abstract
Rationale: Obstructive sleep apnea (OSA) is a common treatable condition with important health and societal consequences. Objectives: We aimed to assess the annual incidence and prevalence of clinically recognized and geographic clustering of OSA in Alberta, Canada, using administrative health data case definitions. Methods: We used two administrative health databases in Alberta to identify ICD-9 and ICD-10 (International Classification of Diseases, Ninth and 10th Revisions, respectively) diagnostic codes for adults and children at least 2 years old diagnosed with OSA between 2003 and 2020. We defined OSA using an algorithm developed and validated in Alberta: at least three claims or one hospitalization within 2 years. We mapped residential postal codes to 70 subregional health authorities (SRHAs). Crude, age group- and sex-specific incidence and prevalence, and age group- and sex-standardized rates were calculated for Alberta and SRHAs. Spatial scan statistics identified clusters of SRHAs in which OSA cases were higher (hot spots) or lower (cold spots) than expected. Results: Between 2003 and 2020, OSA prevalence increased from 0.14% to 4.59%. The annual incidence of OSA increased after 2013. Incidence and prevalence were higher in older adults and children aged 2-11 years compared with 12-17 years. Cluster analysis revealed regional variation in OSA incidence and prevalence over time with no consistent pattern except for cold spots in one large metropolitan center (Calgary). Conclusions: From 2003 to 2020, the incidence and prevalence of clinically recognized OSA increased but varied by geography. Administrative health data can be used to guide interventions aimed at improving health service delivery and the quality of OSA care.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14099. [PMID: 36360976 PMCID: PMC9657551 DOI: 10.3390/ijerph192114099] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 10/19/2022] [Accepted: 10/25/2022] [Indexed: 06/16/2023]
Abstract
The physical fitness of Canadian adults has decreased over the past 30 years, while sedentary time has increased. However, it is unknown if university students studying human movement exhibit similar population declines. Physical fitness (i.e., anthropometrics, musculoskeletal fitness, and aerobic fitness) and habitual activity (e.g., physical activity, stationary time, etc.) was measured in a cohort of kinesiology students (Post30; 2010-2016; n = 129 males, 224 females) using standardized fitness testing and accelerometry, respectively. Physical fitness was compared to data collected on a cohort of students from the same institution and program, 30 years prior (i.e., Pre, 1984-1987, n = 103 males, 73 females). Post30 had greater waist circumference (males: 83.6 ± 9.1 cm vs. 77.8 ± 8.3 cm, females: 77.1 ± 9.7 cm vs. 70.3 ± 5.2 cm, both p < 0.001) and lower estimated maximal aerobic fitness (males: 55 ± 11 vs. 63 ± 7, females: 45 ± 10 vs. 50 ± 7 mLO2/kg/min, both, p < 0.001). Compared to Pre, male Post30 vertical jump (53.6 ± 10.2 vs. 57.0 ± 8.4 cm, p = 0.04) and female Post30 broad jump (178.7 ± 22.1 vs. 186.0 ± 15.5 cm, p < 0.001) were lower. A subsample (n = 65) of Post30 whose habitual activity was assessed, met the aerobic portion of Canadian physical activity guidelines (~400 min/week), but spent excessive amounts of time stationary (10.7 h/day). Current kinesiology students may not be immune to population decreases in physical fitness. Relative to previous group of students interested in movement, fitness was lower in our sample, potentially attributed to excessive stationary time. Regular assessment of physical fitness in kinesiology curriculums may be valuable to understand these declining trends in undergraduate students that mimic population declines in fitness.
