Outcomes of Central Neck Dissection for Papillary Thyroid Carcinoma in Primary Versus Revision Setting.

Introduction: Surgery in the central compartment after previous thyroidectomy involves an increased risk of injury to critical organs, including the parathyroids and recurrent laryngeal nerve. Contrastingly, primary central neck dissection involves a relatively low operative risk. Objective: This study aimed to compare the outcomes of central neck dissection in primary versus revision settings with respect to the lymph node yield and complication rates. Methods: This single-center prospective study included patients who underwent primary or revision neck dissection surgery for histologically confirmed thyroid malignancy between January 2018 and January 2022. Results: We included 30 patients who underwent total thyroidectomy with primary central neck dissection and 29 patients who underwent central neck dissection following remote thyroidectomy with or without previous central dissection. There was no significant between-group difference in postoperative complications, including permanent hypocalcemia and recurrent laryngeal nerve injury. However, both groups showed a significant postoperative decrease in calcium levels even though calcium and parathyroid hormone levels were within reference range. Conclusion: Although many surgeons fear revision central neck dissection, it appears to have similar therapeutic outcomes and complication rates as primary neck dissection for papillary thyroid cancer. Specifically, there were no between-group differences in the lymph node yield, hypoparathyroidism, or recurrent laryngeal nerve paralysis. Patients with normocalcemia showed a significant postoperative reduction in calcium levels, suggesting subclinical parathyroid insufficiency.

The MiniMed 780G automated insulin delivery system adapts to substantial changes in daily routine: Lessons from real world users during Ramadan.

AIM: To report on the effectiveness and safety of the MiniMed 780G automated insulin delivery system in real-world users during the month of Ramadan. MATERIALS AND METHODS: CareLink Personal data were extracted from MiniMed 780G system users from the Gulf region. Users were included if they had ≥10 days of sensor glucose data during the month of Ramadan 2022 as well as in the month before and after. For the main analysis, continuous glucose monitoring endpoints were aggregated per month and were reported by time of day (daytime: 05.31-18.00 h, and night-time). Additional analyses were performed to study the pace at which the algorithm adapts. RESULTS: Glycaemic control was well kept in the 449 included users (mean sensor glucose = 152.6 ± 18.7 mg/dl, glucose management indicator = 7.0 ± 0.4%, time in range = 70.7 ± 11.0%, time below 70 mg/dl = 2.3 ± 2.3%). Albeit some metrics differed from the month before (p < .0001 for all), absolute differences were very small and considered clinically irrelevant. During Ramadan, there was no increased risk of hypoglycaemia during daytime (time below 70 mg/dl = 2.3 ± 2.4%), time in range was highest during daytime (80.0 ± 10.7%, night: 60.4 ± 15.3%), while time above 180 mg/dl was highest during night-time (37.3 ± 16.3%, day: 17.7 ± 10.7%). The algorithm adapted immediately upon lifestyle change. CONCLUSION: The MiniMed 780G automated insulin delivery system is effective, safe and fast in adapting to the substantial changes that occur in the lifestyle of people with type 1 diabetes during Ramadan.

The effectiveness of blood glucose and blood ketone measurement in identifying significant acidosis in diabetic ketoacidosis patients.

BACKGROUND: Patients with diabetic ketoacidosis (DKA), a potentially fatal complication of type 1 diabetes, have hyperglycemia, ketonemia and metabolic acidosis. Blood glucose and blood ketone results are often used to triage patients with suspected DKA. This study aimed to establish how effective blood glucose and blood ketone (beta-hydroxybutyrate, BOHB) measurements are in identifying patients with significant acidosis and sought to validate existing diagnostic BOHB thresholds. METHODS: Initial Emergency Department results on 161 presumptive DKA episodes in 95 patients (42 F, 53 M, age range 14-89 years) containing a complete dataset of D (glucose), K (BOHB) and A (Bicarbonate [HCO3] and pH) results. RESULTS: Blood glucose correlated poorly with BOHB (r = 0.28 p = 0.0003), pH (r= -0.25, p = 0.002) and HCO3 (r= -0.17, p = 0.04). BOHB, though better, was still limited in predicting pH (r = -0.44, p < 0.0001) and HCO3 (r = -0.49, p < 0.0001). A HCO3 of 18mmol/L equated to a BOHB concentration of 4.3mmol/L, whilst a HCO3 of 15mmol/L equated to a BOHB of 4.7mmol/L. Of the 133 of 161 events with HCO3 < 18mmol/L, 22 were not hyperglycemic (> 13.9mmol/L, n = 8), ketonemic (≤ 3mmol/L, n = 9) or either (n = 5). CONCLUSIONS: The commonly employed BOHB diagnostic cutoff of 3mmol/L could not be verified. Since acid-base status was poorly predicted by both glucose and BOHB, this highlights that, regardless of their results, pH and/or HCO3 should also be tested in any patient suspected of DKA.

Global Impact of Obesity.

The prevalence of preobesity and obesity is rising globally, multiple epidemiologic studies have identified preobesity and obesity as predisposing factors to a number of noncommunicable diseases including type 2 diabetes (T2DM), cardiovascular disease (CVD), and cancer. In this review, we discuss the epidemiology of obesity in both children and adults in different regions of the world. We also explore the impact of obesity as a disease not only on physical and mental health but also its economic impact.

A cross-sectional study of the prevalence and clinical management of atherosclerotic cardiovascular diseases in patients with type 2 diabetes across the Middle East and Africa (PACT-MEA): Study design and rationale.

AIM: To investigate the epidemiology and clinical management of patients with type 2 diabetes (T2D) and established atherosclerotic cardiovascular disease (eASCVD) or high/very high ASCVD risk, defined by the 2021 European Society of Cardiology Guidelines, in seven countries in the Middle East and Africa (PACT-MEA; NCT05317845), and to assess physicians' attitudes and the basis for their decision-making in the management of these patients. MATERIALS AND METHODS: PACT-MEA is a cross-sectional, observational study undertaken in Bahrain, Egypt, Jordan, Kuwait, Qatar, South Africa and the United Arab Emirates based on a medical chart review of approximately 3700 patients with T2D in primary and secondary care settings, and a survey of approximately 400 physicians treating patients with T2D. RESULTS: The primary and secondary objectives are to determine the prevalence of eASCVD and high/very high ASCVD risk in patients with T2D. Current treatment with cardioprotective antidiabetic medication, the proportion of patients meeting the treatment criteria for reimbursement in the study countries where there is an applicable reimbursement guideline, and physician-reported factors in clinical decision-making in T2D management, will also be assessed. CONCLUSIONS: This large cross-sectional study will establish the estimated prevalence and management of eASCVD and high/very high ASCVD risk in patients with type 2 diabetes across the Middle East and Africa.

Effect of Date Fruit Consumption on the Glycemic Control of Patients with Type 2 Diabetes: A Randomized Clinical Trial.

Objective. Date fruit has been reported to have benefits in type 2 diabetes (T2D), though there is a concern, given the high sugar content, about its effects on glycemic control. Design and Setting. Prospective, interventional, randomized, parallel study. Participants. In total, 79 patients with T2D (39 male and 40 female). Intervention. Participants were randomly allocated to either 60 g date fruit or 60 g raisins daily of the equivalent glycemic index (amount split, given as midmorning and midafternoon snack) for 12 weeks. Main Outcome Measures. The primary outcome was to investigate the effect of date fruit on HbA1c and fasting blood glucose, and their variability, in patients with T2D in comparison to the same glycemic load of raisins. The secondary outcomes were to determine whether date fruit affected cardiovascular risk by measuring fasting lipids, C-reactive protein (CRP), blood pressure, and insulin resistance (IR) as measured by Homeostatic Model Assessment (HOMA-IR). Results. In total, 61 (27 female and 34 male) of 79 patients completed the study. There was no difference between or within groups for HbA1c or HbA1c variability, fasting glucose or glucose variability, insulin resistance (HOMA-IR), insulin sensitivity (HOMA-S), beta cell function (HOMA-B), the disposition index, lipids, systolic (SBP) or diastolic blood pressure (DBP), or C-reactive protein (CRP) (p > 0.05). Conclusion. No improvement in glycemic indices was seen following supplementation of 60 g daily date fruit or raisins, though neither had a deleterious effect on glycemic control over a 12-week period, indicating their safety when consumed in T2D. Additionally, no beneficial therapeutic effects of date fruit on other cardiovascular indices in T2D were seen.

Sustainable diabetes care services during COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic creates a challenge in the provision of care for patients with diabetes. Furthermore, those with uncontrolled diabetes are at a higher risk for complications due to COVID-19. The purpose of this study is to find an innovative method to sustain effective diabetes care services amidst the COVID-19 pandemic. METHODS: Outpatient diabetes care was successfully transformed from traditional face-to-face encounters in the clinic to an online telemedicine service. RESULTS: 1,972 patients were encountered over a 4-week study period during which we had a low proportion of unreached patients (4%). Some patients were still seen in person because they came as walk-in visits or insisted to be seen in person. CONCLUSION: Telemedicine has become an essential healthcare service and could be augmented by the use of technology like web-based applications and communication via transfer of data from patients' glucometer, insulin pumps, or sensors. Diabetes care can be transitioned to telemedicine effectively and would be successful in reaching more patients than by traditional face-to-face visits. This model of care is time consuming and unfortunately does not reduce the need for medical staff.

Measures of adherence as predictors of early and total weight loss with intensive behavioral therapy for obesity combined with liraglutide 3.0 mg.

Individual weight loss outcomes with intensive behavioral therapy (IBT) for obesity are variable. The present study assessed whether visit attendance, dietary self-monitoring, medication, and meal-replacement adherence were associated with 52-week weight loss with IBT and tested whether these relationships were independent of associations with early weight loss. This was a secondary analysis of a randomized trial in which 150 participants (76.1% female, 55.8% white, BMI = 38.8 ±â€¯4.8 kg/m2) received either IBT alone, IBT with liraglutide 3.0 mg/d, or IBT-liraglutide combined with a 12-week meal replacement diet (Multi-component). In the full sample, visit attendance accounted for 14.8% of the variance in 52-week weight loss and dietary self-monitoring added 14.9%. Only self-monitoring was independently associated with weight loss. In the 100 liraglutide-treated participants, medication adherence accounted for an additional 9.9% of the variance in 52-week weight loss, and both self-monitoring and medication adherence were independent correlates. For the 50 Multi-component participants, meal replacement adherence did not predict weight loss. Early weight loss was associated with higher early and subsequent session attendance and dietary self-monitoring. However, self-monitoring and medication adherence remained important correlates of total weight loss when controlling for this variable. Strategies that help improve self-monitoring consistency and medication usage could improve weight loss with IBT.

Mindful Eating, General Mindful Awareness, and Acceptance as Predictors of Weight Loss.

OBJECTIVES: The goal of the present study was to determine whether baseline mindful eating, general mindful awareness, or acceptance was most strongly associated with short- and long-term weight loss in a lifestyle modification program. METHODS: Data were from 178 participants (baseline BMI=40.9±5.9 kg/m2, age=44.2±11.2 years; 87.6% female; 71.3% black) who enrolled in a two-phase trial. All participants attended an initial 14-week lifestyle modification program that included a meal replacement diet. Participants who had lost ≥5% of initial weight (N=137) were then randomized to 52 weeks of lifestyle modification with lorcaserin or placebo. Linear mixed models examined whether mindful eating (Mindful Eating Questionnaire) and general mindful awareness and acceptance (Philadelphia Mindfulness Scale) predicted short-term weight loss at week 14 in the full sample and long-term weight loss at the end of the trial in the subsample of randomized participants. RESULTS: In the full sample, higher baseline acceptance predicted greater short-term weight losses (p=.004). At week 14, individuals low in acceptance (-1SD) lost an average of 8.7 kg (SE=0.6) compared to 11.2 kg (SE=0.6) among those high in acceptance (+1SD). In the subsample of participants who successfully lost weight in phase 1, the independent effect of acceptance on total losses at the end of the trial did not reach statistical significance (p=.058). Neither mindful eating nor general mindful awareness independently predicted weight loss at either time point. CONCLUSIONS: Acceptance was a stronger predictor than either general or eating-specific awareness of weight loss with lifestyle modification.

Effects of liraglutide on appetite, food preoccupation, and food liking: results of a randomized controlled trial.

BACKGROUND: Some weight loss medications, including liraglutide 3.0 mg, are thought to facilitate weight loss by improving appetite control. However, no studies have evaluated their long-term appetitive effects. SUBJECTS/METHODS: This study examined changes in appetite in a subsample of 113 adults with obesity (76.1% female, 55.8% white, BMI = 38.8 ± 4.8 kg/m2) who participated in a 52-week trial. Participants were randomized to intensive behavioral therapy alone (IBT-alone), IBT with liraglutide 3.0 mg/day (IBT-liraglutide), or IBT-liraglutide combined with a 12-week meal replacement diet (Multi-component). Participants rated their hunger, fullness after meals, liking of meals, and food preoccupation (all as experienced over the past week) using visual analogue scales (0-100 mm). Ratings were completed at baseline and eight subsequent visits over the year. RESULTS: At week 52, participants treated by IBT-alone lost 6.2 ± 1.6% of baseline weight, compared with 11.8 ± 1.6% and 12.1 ± 1.5% in the IBT-liraglutide and Multi-component groups, respectively. Compared to IBT-alone, IBT-liraglutide participants reported larger reductions at week 6 in hunger (-0.3 ± 4.2 vs -16.8 ± 4.0 mm, p = .005) and food preoccupation (+0.2 ± 3.7 vs -16.3 ± 3.6 mm, p = .002) and larger increases in fullness (-5.1 ± 3.2 vs +9.8 ± 3.0 mm, p = .001). These significant differences persisted at all assessments through week 24. There were no differences between IBT-alone and IBT-liraglutide in meal liking. IBT-alone and Multi-component participants differed in hunger at week 6, and in food preoccupation at all assessments through week 24. Multi-component participants reported reduced liking of meals relative to the IBT-alone and IBT-liraglutide groups through weeks 40 and 52, respectively. There were no other differences among any groups at week 52. CONCLUSIONS: Consistent with short-term studies, IBT-liraglutide participants reported greater improvements in hunger, fullness, and food preoccupation than those assigned to IBT-alone. Differences in appetite persisted for 24 weeks but were not maintained at week 52, despite the relatively greater weight losses in the liraglutide-treated participants at the trial's end.

Associations between causal attributions for obesity and long-term weight loss.

Obesity is a complex disease caused by a wide array of behavioral, biological, and environmental factors. However, obesity is often attributed to oversimplified and stigmatizing causal factors such as laziness, lack of willpower, and failure to take personal responsibility for one's health. Understanding of the causal factors that contribute to obesity among people with obesity may affect their weight management efforts. The current study explored associations between causal attributions for obesity and long-term weight loss, as well as examined potential changes in attributions with weight reduction. The 16-item Causal Attributions for Obesity scale (rated 1-7) was administered to 178 patients seeking behavioral/pharmacological weight-loss treatment. Causal attributions and weight were assessed at baseline, after 14 weeks of a low-calorie diet, and again at weeks 24 and 52 of a subsequent randomized trial (i.e., 66 weeks total). Logistic and linear regression examined effects of baseline causal attribution ratings on weight loss. Higher baseline ratings of personal responsibility attributions predicted 38% reduced odds of achieving ≥10% weight loss at week 52 (p = 0.02). Causal attribution ratings did not change over time or correlate continuously with weight change. Thus, attributing obesity to a failure of personal responsibility may impair long-term weight management efforts for individuals seeking ≥10% weight loss. Targeted techniques are needed to reduce patients' stigmatizing beliefs about the causes of obesity.

Effects of Liraglutide and Behavioral Weight Loss on Food Cravings, Eating Behaviors, and Eating Disorder Psychopathology.

OBJECTIVE: This exploratory analysis examined the effects of intensive behavioral therapy (IBT) for obesity ("IBT-alone"), IBT plus liraglutide 3.0 mg/d ("IBT-liraglutide"), and IBT plus liraglutide 3.0 mg/d plus 12 weeks of a portion-controlled diet that provided 1,000 to 1,200 kcal/d ("Multicomponent") on changes in food cravings, eating behaviors, and eating disorder psychopathology at 24 and 52 weeks post randomization. METHODS: Adults with obesity (mean age = 47.6 ± 11.8 years and BMI = 38.4 ± 4.9 kg/m2 ; 79.3% female; 54.0% non-Hispanic white; 44.7% black) were randomized to IBT-alone (n = 50), IBT-liraglutide (n = 50), or Multicomponent (n = 50). RESULTS: At weeks 24 and 52, liraglutide-treated groups reported significantly larger declines in weight concern relative to the IBT-alone group. At week 24, compared with IBT-alone, liraglutide-treated groups reported significantly greater reductions in dietary disinhibition, global eating disorder psychopathology, and shape concern. The Multicomponent group had significantly greater reductions in binge eating at week 24 relative to the IBT-alone group. However, differences among groups were no longer significant at week 52. Groups did not differ in total food cravings at week 24 or 52. CONCLUSIONS: The combination of liraglutide and IBT was associated with greater short-term improvements in dietary disinhibition, global eating disorder psychopathology, and shape concern than IBT alone.

Changes in health-related quality of life with intensive behavioural therapy combined with liraglutide 3.0 mg per day.

This study examined the effects of intensive behavioural therapy (IBT) for obesity (IBT-alone), IBT plus liraglutide 3.0 mg/day (IBT-liraglutide), and IBT-liraglutide combined with 12 weeks of a portion-controlled diet (Multicomponent) on changes in general health-related (HR) quality of life (QoL) and weight-related QoL. Adults with obesity (79.3% female; 54.0% white; 44.7% black; mean age = 47.6 ± 11.8 years and body mass index = 38.4 ± 4.9 kg/m2 ) were randomized to IBT-alone (n = 50), IBT-liraglutide (n = 50) or Multicomponent (n = 50). General HRQoL was measured with the Short Form-36 (SF-36), and weight-related QoL was assessed with the Impact of Weight on Quality of Life-Lite scale. At week 52, participants in the three groups lost 6.1 ± 1.3%, 11.5 ± 1.3% and 11.8 ± 1.3% of initial body weight, respectively. Both liraglutide-treated groups were significantly more likely than IBT-alone to achieve clinically meaningful improvements in total weight-related QoL. They also both achieved greater improvements than IBT-alone in weight-related public distress and in general mental health, as measured by the SF-36 mental component summary score. Independent of treatment group, greater categorical weight loss was associated with greater improvements in several domains of both general and weight-related QoL. The addition of liraglutide to IBT appeared to improve aspects of both general HRQoL and weight-related QoL.

Differential Effects of Roux-en-Y Gastric Bypass Surgery and Laparoscopic Sleeve Gastrectomy on Fatty Acid Levels.

BACKGROUND: Bariatric surgery is associated with improved cardiovascular outcomes and also affects lipid levels, but few studies have compared the effects of Roux-en-Y gastric bypass (RYGB) surgery with those of laparoscopic sleeve gastrectomy (LSG) on serum fatty acid levels. The present study compares the effects of RYGB and LSG surgeries on serum fatty acid levels. METHODS: The study participants were women who were undergoing either RYGB or LSG and body mass index (BMI)-matched controls. Fasting blood samples to measure glucose, insulin, and fatty acids were drawn at baseline and at 6 and 18 months from baseline. RESULTS: Serum fatty acid data were available for 57 participants at baseline, of whom 56 had data at 6 months and 41 had data at 18 months from baseline. Compared with baseline, serum non-esterified fatty acids (NEFAs) levels were significantly higher at 6 and 18 months in the LSG group compared with the RYGB group. In the RYGB group, 2 saturated fatty acids (SFAs), 2 monounsaturated fatty acids (MUFAs), and 1 polyunsaturated fatty acid (PUFA) were significantly decreased after surgery, compared with those of the LSG group. CONCLUSIONS: A significant increase in NEFAs was seen after LSG, compared with RYGB. Compared with the LSG group, several serum fatty acids were significantly reduced after RYGB. TRIAL REGISTRATION: NCT01228097.

Perceptions of a large amount of food based on binge-eating disorder diagnosis.

OBJECTIVE: This study examined what adults with binge-eating disorder (BED) and obesity perceived as the threshold for a large amount of food and how their evaluations compared to ratings by participants with obesity but without BED. METHOD: This was a cross-sectional study of 150 participants with obesity. BED was assessed using the Questionnaire on Eating and Weight Patterns and confirmed via interview. Participants completed the Eating Patterns Questionnaire and Eating Inventory. RESULTS: Participants with BED had significantly higher thresholds for a large amount of food relative to those without BED. Compared to participants without BED, those with BED had significantly higher thresholds on 13 of the 22 food items. In the overall sample, being male and having higher hunger scores were associated with greater thresholds. DISCUSSION: Individuals with obesity and BED had larger portion standards than participants without BED. Individuals with BED may benefit from interventions targeted toward decreasing perceptions of portion sizes.

Effects of liraglutide plus phentermine in adults with obesity following 1 year of treatment by liraglutide alone: A randomized placebo-controlled pilot trial.

BACKGROUND: This pilot study evaluated whether adding phentermine to liraglutide would induce further weight loss in participants who had previously lost weight with liraglutide alone. SUBJECTS/METHODS: Participants were 45 adults with obesity (75.6% female, 55.6% white, body mass index = 34.3 ±â€¯4.7 kg/m2) who had lost an average of 12.6 ±â€¯6.8% of initial weight during a prior 1-year randomized trial with liraglutide and intensive behavioral treatment. Participants were re-randomized, in a double-blinded fashion, to liraglutide 3.0 mg plus phentermine 15.0 mg (liraglutide-phentermine) or liraglutide plus placebo (liraglutide-placebo). Participants also were provided with four, 15-minute counseling sessions during the 12-week extension study. RESULTS: At week 12, the liraglutide-phentermine and liraglutide-placebo groups lost a mean (±SEM) of 1.6 ±â€¯0.6% and 0.1 ±â€¯0.5% of re-randomization weight, respectively (p = 0.073). Two (9.1%) liraglutide-phentermine participants and one (4.3%) liraglutide-placebo participant lost ≥5% of re-randomization weight; 19 (86.4%) and 16 (69.9%) participants, respectively, maintained their full weight loss achieved in the prior 1-year trial (p = 0.125). Liraglutide-phentermine participants generally reported larger reductions in hunger and food preoccupation than liraglutide-placebo participants during the first 8 weeks of the extension study. CONCLUSIONS: The combination of liraglutide and phentermine appeared to be well-tolerated but did not produce additional clinically meaningful weight loss in individuals who had already lost 12.6% of initial weight with liraglutide alone. TRIAL REGISTRATION: ClinicalTrials.gov number, NCT02911818.

Effects of addictive-like eating behaviors on weight loss with behavioral obesity treatment.

To examine the relationship between food cravings and food addiction as defined by the Yale Food Addiction Scale (YFAS) and to assess the effects of these variables on weight loss during a 14-week group lifestyle modification program. Data were from 178 participants who were prescribed a 1000-1200 kcal/day portion-controlled diet and provided with weekly group lifestyle modification sessions. Participants completed the Food Craving Inventory and YFAS pre- and post-treatment. Weight was measured weekly. Participants with YFAS-defined food addiction (6.7%) reported more frequent overall food cravings relative to those without food addiction. More frequent food cravings at baseline were associated with less weight loss over the 14 weeks. Analyzed categorically, participants in the highest tertile of baseline food cravings lost 7.6 ± 0.5% of initial weight, which was significantly less compared to those in the lowest tertile who lost 9.1 ± 0.5%. Percent weight loss did not differ significantly between participants with YFAS-defined food addiction (6.5 ± 1.2%) and those who did not meet criteria (8.6 ± 0.3%). Addictive-like eating behaviors significantly declined from pre- to post-treatment. Participants with frequent food cravings lost less weight than their peers. Targeted interventions for food cravings could improve weight loss in these individuals. Few participants met YFAS-defined criteria for food addiction. Addictive-like eating behaviors tended to decline during behavioral weight loss, but neither baseline nor change in YFAS scores predicted weight loss.

Early Weight Loss in Behavioral Treatment Predicts Later Rate of Weight Loss and Response to Pharmacotherapy.

BACKGROUND: Early weight loss (EWL) in the first 1-2 months of behavioral treatment is a strong predictor of later total weight loss. It is not clear whether participants with lower early losses lose less in ongoing treatment or simply fail to overcome the smaller initial loss. Furthermore, no study has tested whether EWL in behavioral treatment predicts response to a different treatment modality, such as pharmacotherapy. METHODS: Data were from 170 participants with obesity (baseline BMI = 40.8 ± 5.8 kg/m2, 87.6% female; 71.3% Black) enrolled in a two-phase trial. Data from the weight loss phase, which provided weekly lifestyle counseling and a meal replacement diet, were used to examine the relationship between 4-week EWL and subsequent rate of weight loss in behavioral treatment. Data from the maintenance phase, in which 137 participants who had lost ≥5% of initial weight were randomized to 52 weeks of maintenance counseling with lorcaserin or placebo, were used to determine whether EWL with behavioral treatment affects the benefit of pharmacotherapy. RESULTS: EWL in the first 4 weeks of behavioral treatment (3.6 ± 1.7%) predicted greater total losses at Week 14 (r2 = 0.61, p < .001) and a faster rate of weight loss in the subsequent 9 weeks of the program (p < .001). During the maintenance phase, lower EWL in behavioral treatment predicted a greater benefit of lorcaserin, in comparison with placebo, for the maintenance of a ≥5% loss at Weeks 24 and 52. CONCLUSIONS: These findings support recommendations to modify treatment for individuals with low EWL.

Weight Bias Internalization and Long-Term Weight Loss in Patients With Obesity.

BACKGROUND: The relationship between weight bias internalization (WBI) and long-term weight loss is largely unknown. PURPOSE: To determine the effects of weight loss on WBI and assess whether WBI impairs long-term weight loss. METHODS: One hundred thirty-three adults with obesity completed the Weight Bias Internalization Scale (WBIS) at baseline, after a 14-week lifestyle intervention in which they lost ≥5 per cent of initial weight, and at weeks 24 and 52 of a subsequent randomized controlled trial (RCT) for weight-loss maintenance (66 weeks total). Linear mixed models were used to examine the effects of weight loss on WBIS scores and the effects of baseline WBIS scores on weight change over time. Logistic regression was used to determine the effects of baseline WBIS scores on achieving ≥5 and ≥10 per cent weight loss. RESULTS: Changes in weight did not predict changes in WBIS scores. Baseline WBIS scores predicted reduced odds of achieving ≥5 and ≥10 per cent weight loss at week 24 of the RCT (p values < .05). At week 52, the interaction between participant race and WBIS scores predicted weight loss (p = .046) such that nonblack (but not black) participants with higher baseline WBIS scores had lower odds of achieving ≥10 per cent weight loss (OR = 0.38, p = .01). Baseline WBIS scores did not significantly predict rate of weight change over time. CONCLUSIONS: Among participants in a weight loss maintenance trial, WBI did not change in relation to changes in weight. More research is needed to clarify the effects of WBI on long-term weight loss and maintenance across race/ethnicity. CLINICAL TRIALS REGISTRATION: ClinicalTrials.gov identifier NCT02388568.
