RESUMO
OBJECTIVE: Evidence to date, while sparse, suggests that patients taking long-term opioids require special considerations and protections to prevent potential iatrogenic harms from opioid de-prescribing, such as increased pain or suffering. Following this study protocol, the EMPOWER study seeks to address multiple unmet needs of patients with chronic pain who desire to reduce long-term opioid therapy, and provide the clinical evidence on effective methodology. METHODS: EMPOWER applies patient-centered methods for voluntary prescription opioid reduction conducted within a comprehensive, multi-state, 3-arm randomized controlled comparative effectiveness study of three study arms (1) group cognitive behavioral therapy for chronic pain; (2) group chronic pain self-management; and (3) usual care (taper only). Specialized electronic data capture systems collect patient reported symptoms and satisfaction data weekly and monthly during the taper, with real-time clinical alerts and electronic feedback loops informing, documenting, and steering needed care actions. CONCLUSION: The EMPOWER study seeks to provide granular evidence on patient response to voluntary opioid tapering, and will provide evidence to inform clinical systems changes, clinical care, patient satisfaction, and patient outcomes for opioid reduction.

OBJECTIVE: To examine whether depression symptoms or antidepressant medication (ADM) use predicts the probability of cardiovascular events in overweight/obese individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS: Preplanned analyses of depression and incident cardiovascular disease (CVD) were performed in the Look AHEAD (Action for Health in Diabetes) weight loss trial after a median follow-up of 9.6 years. Depression symptoms, assessed with the Beck Depression Inventory (BDI), were analyzed both as a continuous and dichotomized variable (BDI score <10 or ≥10). ADM use was coded from participants' prescription medications. Four composite CVD outcomes were defined in the study protocol. Sex-stratified Cox proportional hazards models were adjusted for a range of baseline covariates. RESULTS: Depression symptoms were only significantly associated with a composite secondary outcome comprising CVD death, nonfatal myocardial infarction, nonfatal stroke, hospitalized angina, congestive heart failure, peripheral vascular disease, coronary artery bypass graft, and carotid endarterectomy. Significant sex interactions were observed for BDI score and BDI score ≥10. BDI score was significantly associated with higher probability of this composite outcome in men but was not associated with the outcome in women. BDI score ≥10 was positively associated with this composite outcome in men but was negatively associated in women. Exploratory analysis identified a significant BDI ≥10 × ADM use interaction for this composite outcome that differed in men versus women. Men with both BDI score ≥10 and ADM use compared with those with neither had 60% higher probability of the outcome, whereas women with both compared with those with neither had 50% lower probability. CONCLUSIONS: Sex differences in the association of depression symptoms and ADM use with incident CVD warrant further investigation.

This retrospective and comparative survey investigates an unusual number of stress fractures seen within a Division I college cross-country team. An anonymous questionnaire-designed to observe factors known to increase stress fracture incidence-was distributed to members of the current and previous seasons' teams. Running surface, sleep hours, intake of calcium, and shoe type were among the factors investigated. Eleven lower extremity stress fractures were found in nine athletes. Athletes with stress fractures reported significantly fewer workouts per week on the new track. All other study parameters had no statistically significant effect on stress fractures in these athletes.

BACKGROUND: It is unknown whether intentional weight loss provides long-term benefits for cognitive function. METHODS: An ancillary study to a randomized controlled clinical trial was conducted in overweight and obese individuals (N = 978), aged 45-76 years at enrollment, with type 2 diabetes. An intensive behavioral intervention designed to promote and maintain weight loss through caloric restriction and increased physical activity was compared with diabetes support and education. Standardized assessments of cognitive function were collected an average of 8.1 years after trial enrollment. RESULTS: Participants assigned to intensive lifestyle intervention lost a mean (SE) 11.1% (0.4%) and 7.2% (0.5%) of weight at Years 1 and 8, respectively, compared with 1.0% (0.2%) and 3.3% (0.5%) in the control group (p < .001). Covariate-adjusted mean composite cognitive function test scores were similar for the two groups (p = .69), and no significant differences were found for any individual cognitive test. There was some evidence of a differential effect (nominal interaction p = .008) for a prespecified comparison: Intensive lifestyle intervention was associated with a relative mean benefit for composite cognitive function of 0.276 (95% confidence interval: 0.033, 0.520) SDs among individuals with body mass index less than 30 kg/m(2) at baseline compared with a relative mean deficit of 0.086 (-0.021, 0.194) SDs among individuals with body mass more than or equal to 30 kg/m(2). CONCLUSIONS: Eight years of intensive lifestyle intervention did not alter cognitive function in obese adults with type 2 diabetes; however, there was evidence for benefit among overweight but not obese individuals. Changes in cognition were not assessed in this cross-sectional study.

OBJECTIVE: To identify baseline attributes associated with consecutively missed data collection visits during the first 48 months of Look AHEADa randomized, controlled trial in 5,145 overweight/obese adults with type 2 diabetes designed to determine the long-term health benefits of weight loss achieved by lifestyle change. DESIGN AND METHODS: The analyzed sample consisted of 5,016 participants who were alive at month 48 and enrolled at Look AHEAD sites. Demographic, baseline behavior, psychosocial factors, and treatment randomization were included as predictors of missed consecutive visits in proportional hazard models. RESULTS: In multivariate Cox proportional hazard models, baseline attributes of participants who missed consecutive visits (n 5 222) included: younger age (hazard ratio [HR] 1.18 per 5 years younger; 95% confidence Interval 1.05, 1.30), higher depression score (HR 1.04; 1.01, 1.06), non-married status (HR 1.37; 1.04, 1.82), never self-weighing prior to enrollment (HR 2.01; 1.25, 3.23), and randomization to minimal vs. intensive lifestyle intervention (HR 1.46; 1.11, 1.91). CONCLUSIONS: Younger age, symptoms of depression, non-married status, never self-weighing, and randomization to minimal intervention were associated with a higher likelihood of missing consecutive data collection visits, even in a high-retention trial like Look AHEAD. Whether modifications to screening or retention efforts targeted to these attributes might enhance long-term retention in behavioral trials requires further investigation.

OBJECTIVE: Predicting outcome in weight loss trials from baseline characteristics has proved difficult. Readiness to change is typically measured by self-report. METHODS: Performance of a behavioral task, completion of food records, from the screening period in the Look AHEAD study (n = 549 at four clinical centers) was assessed. Completeness of records was measured by the number of words and Arabic numerals (numbers) recorded per day, the number of eating episodes per day, and days per week where physical activity was noted. The primary outcome was weight loss at one year. RESULTS: In univariable analysis, both the number of words recorded and the number of numbers recorded were associated with greater weight loss. In multivariable analysis, individuals who recorded 20-26, 27-33, and ≥34 words per day lost 9.12%, 11.40%, and 12.08% of initial weight, compared to 8.98% for individuals who recorded less than 20 words per day (P values of 0.87, 0.008, and <0.001, respectively, compared to <20 words per day). CONCLUSIONS: Participants who kept more detailed food records at screening lost more weight after 1 year than individuals who kept sparser records. The use of objective behavioral screening tools may improve the assessment of weight loss readiness.

OBJECTIVE: We examined the effects of an intensive lifestyle intervention (ILI), compared with a diabetes support and education (DSE) control intervention, on long-term changes in depression symptoms, antidepressant medication (ADM) use, and health-related quality of life (HRQoL) in overweight/obese individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS: Look AHEAD was a multisite randomized controlled trial of 5,145 overweight/obese participants assigned to ILI (designed to produce weight loss) or DSE and followed for a median of 9.6 years. The Beck Depression Inventory (BDI) was administered at baseline, annually at years 1-4, and again at year 8. Mean BDI scores and incidence of BDI scores ≥10, indicative of likely mild or greater depression, were examined. Annually through year 10, participants reported their ADM use and completed the Medical Outcomes Study Short Form 36 (SF-36) questionnaire, which yields physical component summary (PCS) and mental component summary (MCS) scores. RESULTS: ILI significantly reduced the incidence of mild or greater depression symptoms (BDI scores ≥10) compared with DSE (hazard ratio [HR] = 0.85; 95% CI 0.75-0.97; P = 0.0145). Although SF-36 PCS scores worsened over time in both groups, ILI participants reported better physical function than DSE throughout the first 8 years (all P values <0.01). There were no significant differences between treatment arms in the proportion of participants who used ADMs or in SF-36 MCS scores. CONCLUSIONS: ILI for overweight/obese patients with type 2 diabetes may reduce the risk of developing clinically significant symptoms of depression and preserve physical HRQoL. These findings should be considered when evaluating the potential benefits of ILIs.

OBJECTIVE: Sexual dysfunction is a prevalent problem in obese women with type 2 diabetes. This study examined the effects of intensive lifestyle intervention (ILI) in these women. RESEARCH DESIGN AND METHODS: Look AHEAD is a 16-center, randomized, controlled trial evaluating the health effects of ILI compared with a control group (diabetes support and education [DSE]). The Look AHEAD Sexual Function Ancillary study included 375 female participants at five Look AHEAD sites. Participants completed the Female Sexual Function Inventory (FSFI) and Beck Depression Inventory (BDI), and assessments of weight and cardiovascular risk factors at baseline and 1 year were made. RESULTS: At baseline, 50% of the 229 participants who reported being sexually active met criteria for female sexual dysfunction (FSD); only BDI score was related to FSD. One-year weight losses were greater in the ILI group than in the DSE group (7.6 vs. 0.45 kg; P<0.001). Among women with FSD at baseline, those in the ILI group (N=60) compared with those in the DSE group (N=53) were significantly more likely to remain sexually active (83 vs. 64%; P<0.008), reported greater improvement in total FSFI scores and in most FSFI domains (P<0.05), and were more likely to experience remission of FSD (28 vs. 11%; P<0.04) at 1 year. No significant differences between ILI and DSE were seen in women who did not have FSD at baseline. CONCLUSIONS: Participation in ILI appeared to have beneficial effects on sexual functioning among obese women with diabetes, particularly in those who had FSD at baseline.

Depressed individuals are frequently excluded from weight loss trials because of fears that weight reduction may precipitate mood disorders, as well as concerns that depressed participants will not lose weight satisfactorily. The present study examined participants in the Look AHEAD study to determine whether moderate weight loss would be associated with incident symptoms of depression and suicidal ideation, and whether symptoms of depression at baseline would limit weight loss at 1 year. Overweight/obese adults with type 2 diabetes (n = 5,145) were randomly assigned to an Intensive Lifestyle Intervention (ILI) or a usual care group, Diabetes Support and Education (DSE). Of these, 5,129 participants completed the Beck Depression Inventory (BDI) and had their weight measured at baseline and 1 year. Potentially significant symptoms of depression were defined by a BDI score ≥10. Participants in ILI lost 8.6 ± 6.9% of initial weight at 1 year, compared to 0.7 ± 4.8% for DSE (P < 0.001, effect size = 1.33), and had a reduction of 1.4 ± 4.7 points on the BDI, compared to 0.4 ± 4.5 for DSE (P < 0.001, effect size = 0.23). At 1 year, the incidence of potentially significant symptoms of depression was significantly lower in the ILI than DSE group (6.3% vs. 9.6%) (relative risk (RR) = 0.66, 95% confidence interval (CI) = 0.5, 0.8; P < 0.001). In the ILI group, participants with and without symptoms of depression lost 7.8 ± 6.7% and 8.7 ± 6.9%, respectively, a difference not considered clinically meaningful. Intentional weight loss was not associated with the precipitation of symptoms of depression, but instead appeared to protect against this occurrence. Mild (or greater) symptoms of depression at baseline did not prevent overweight/obese individuals with type 2 diabetes from achieving significant weight loss.

The research reviewed within this article provides support for both the cognitive and behavioral components of cognitive behavioral weight-loss interventions. Lifestyle based treatments have produced markedly improved results in the past 20 years, in part attributable to changes in treatment structure. Use of pretreatment participant preparation strategies, extended treatment periods with clearly defined weight-loss goals, combining multiple dietary and physical activity strategies, and increasing emphasis on long-term provider contact and relapse prevention have modestly improved long-term weight maintenance. Several investigators have emphasized the need to incorporate additional cognitive components into the cognitive-behavioral treatment of obesity to improve both short- and long-term outcomes. Furthermore, continued insights into metabolic changes producing an energy gap after weight loss should no doubt continue to refine insights into the behavioral requirements of long-term weight loss. Despite increased awareness and behavioral treatment advances, the worldwide prevalence of obesity and weight-related chronic illnesses continues to expound. Behavioral treatment is inherently challenging and time-consuming, and readily available to only a fraction of the population who may benefit from inclusion. Several investigators have cautioned that individual or small group-based interventions are insufficient to serve the population masses requiring treatment, and that continued development of community or Web-based programs, and community-development tactics to increase healthy lifestyles, are needed. The call has been sounded to conceptualize obesity as a chronic health condition requiring lifelong treatment. As such, the conceptualization of cognitive-behavioral therapies as a one-time treatment is passe´ . As the current number of obesity specialists and behaviorally trained professionals is insufficient to combat this problem; an increased emphasis upon training nontraditional weight specialists and nonbehavioral community providers is obviated.

BACKGROUND: Academic detailing in nursing homes (NHs) has been shown to improve drug use patterns and adherence to guidelines. OBJECTIVE: The purpose of this study was to evaluate the impact of a multidisciplinary intervention that included academic detailing on adherence to national nursing home-acquired pneumonia (NHAP) guidelines related to use of antibiotics. METHODS: This quasi-experimental study evaluated the effects of a 2-year multifaceted and multidisciplinary intervention targeting implementation of national evidence-based guidelines for NHAP. Interventions took place in 8 NHs in Colorado; 8 NHs in Kansas and Missouri served as controls. Interventions included (1) educational sessions for nurses to improve recognition and timely treatment of NHAP symptoms and (2) academic detailing to clinicians by pharmacists regarding diagnostic and prescribing practices. Differences in antibiotic use between groups were compared after 2 intervention years relative to baseline. RESULTS: A total of 549 episodes of NHAP were evaluated in the intervention group and 574 in the control group. Compared with baseline, 1 facility in the intervention group significantly improved in guideline adherence for optimal antibiotic use (P = 0.007), whereas no facilities in the control group improved. The mean adherence score for optimal antibiotic use in intervention NHs increased from 60% to 66%, whereas the control NHs increased from 32% to 39% (P = 0.3). Mean adherence to guidelines recommending antibiotic use within 4 hours of NHAP diagnosis increased from 57% to 75% in intervention NHs but decreased from 38% to 31% in control NHs (P = 0.0003 for difference). There was no difference between intervention and control NHs for guideline adherence regarding optimal duration of antibiotic use. CONCLUSIONS: The ability of this multifaceted study to repeatedly remind nursing staff of the importance of timely antibiotic administration contrasts with its limited academic detailing interaction with clinicians. This difference within the intervention may explain the differential impact of the intervention on antibiotic guideline adherence.

OBJECTIVE: Determine whether a comprehensive approach to implementing national consensus guidelines for nursing home-acquired pneumonia (NHAP) affected hospitalization rates. DESIGN: Quasi-experimental, mixed-methods, multifaceted, unblinded intervention trial. SETTING: Sixteen nursing homes (NHs) from 1 corporation: 8 in metropolitan Denver, CO; 8 in Kansas and Missouri during 3 influenza seasons, October to April 2004 to 2007. PARTICIPANTS: Residents with 2 or more signs and symptoms of systemic lower respiratory tract infection (LRTI); NH staff and physicians were eligible. INTERVENTION: Multifaceted, including academic detailing to clinicians, within-facility nurse change agent, financial incentives, and nursing education. MEASUREMENTS: Subjects' NH medical records were reviewed for resident characteristics, disease severity, and care processes. Bivariate analysis compared hospitalization rates for subjects with stable and unstable vital signs between intervention and control NHs and time periods. Qualitative interviews were analyzed using content coding. RESULTS: Hospitalization rates for stable residents in both NH groups remained low throughout the study. Few critically ill subjects in the intervention NHs were hospitalized in either the baseline or intervention period. In control NHs, 8.7% of subjects with unstable vital signs were hospitalized during the baseline and 33% in intervention year 2, but the difference was not statistically significant (P = .10). Interviews with nursing staff and leadership confirmed there were significant pressures for, and enablers of, avoiding hospitalization for treatment of acute infections. CONCLUSIONS: Secular pressures to avoid hospitalization and the challenges of reaching NH physicians via academic detailing are likely responsible for the lack of intervention effect on hospitalization rates for critically ill NH residents.

BACKGROUND: Inconsistent findings have been reported regarding improved health-related quality of life (HRQOL) after weight loss. We tested the efficacy of a weight management program for improving HRQOL in overweight or obese adults diagnosed as having type 2 diabetes mellitus. METHODS: We conducted a randomized multisite clinical trial at 16 outpatient research centers with 2 treatment arms and blinded measurements at baseline and the end of year 1. A total of 5145 participants (mean [SD] age, 58.7 [6.9] years; mean [SD] body mass index [calculated as weight in kilograms divided by height in meters squared], 36.0 [5.9]; 59.5% women; 63.1% white) were randomized to an intensive lifestyle intervention (ILI) or to diabetes support and education (DSE). Main outcome measures included the 36-Item Short-Form Health Survey physical component summary (PCS) and mental health component summary (MCS) scores and Beck Depression Inventory II (BDI-II) scores. Baseline mean (SD) scores were 47.9 (7.9) for PCS, 54.0 (8.1) for MCS, and 5.7 (5.0) for BDI-II. RESULTS: Improved HRQOL was demonstrated by the PCS and BDI-II scores (P < .001) in the ILI arm compared with the DSE arm. The largest effect was observed for the PCS score (difference, -2.91; 99% confidence interval, -3.44 to -2.37). The greatest HRQOL improvement occurred in participants with the lowest baseline HRQOL levels. Mean (SD) changes in weight (ILI, -8.77 [8.2] kg and DSE, -0.86 [5.0] kg), improved fitness, and improved physical symptoms mediated treatment effects associated with the BDI-II and PCS. CONCLUSIONS: Overweight adults diagnosed as having type 2 diabetes experienced significant improvement in HRQOL by enrolling in a weight management program that yielded significant weight loss, improved physical fitness, and reduced physical symptoms.

Cognitive behavioral interventions have formed the cornerstone of obesity treatment for the past two decades. These techniques, often combined with diet and exercise strategies, have been shown to produce weight losses of sufficient magnitude so as to reduce health risks. Though success in producing short-term weight loss is improving, many factors, including a metabolic energy gap, continue to challenge long-term weight maintenance results. This article reviews the unique influence of cognitive, behavioral, and metabolic factors on weight loss and weight-loss maintenance, and how future treatment packages might be modified to improve long-term weight loss outcomes.

Within the past two decades, motivational interviewing has emerged as a useful strategy to help individuals develop motivation to change health behavior and sustain those efforts. This article reviews the preliminary but burgeoning literature that supports the effectiveness of motivational interviewing strategies in promoting positive changes in a variety of health behaviors, including dietary change, activity increases, and regimen adherence. A variety of adaptations of the motivational interviewing process are discussed as relevant to making this treatment strategy increasingly applicable to a variety of health care settings.

OBJECTIVE: To determine the prevalence of binge eating disorder (BED) and night eating syndrome (NES) among applicants to the Look AHEAD (Action for Health in Diabetes) study. RESEARCH METHODS AND PROCEDURES: The Eating Disorders Examination-Questionnaire (EDE-Q) and the Night Eating Questionnaire (NEQ) were used to screen patients. Phone interviews were conducted using the EDE for those who reported at least eight episodes of objective binge eating in the past month and using the Night Eating Syndrome History and Interview for those who scored > or =25 on the NEQ. Recruitment at four sites (Birmingham, n = 200; Houston, n = 259; Minneapolis, n = 182; and Philadelphia, n = 204) yielded 845 participants (58% women; mean age = 60.1 +/- 6.7 years; mean BMI = 36.2 +/- 6.3 kg/m(2)). RESULTS: Screening scores were met by 47 (5.6%) applicants on the EDE-Q and 71 (8.4%) on the NEQ. Of the 85% (40/47) who completed the EDE interview, 12 were diagnosed with BED, representing 1.4% of the total sample. Of the 72% (51/71) who completed the Night Eating Syndrome History and Interview, 32 were diagnosed with NES, equal to 3.8% of the total sample. Three participants had both BED and NES. Participants with eating disorders were younger, heavier, and reported more eating pathology than those without eating disorders. DISCUSSION: Among obese adults with type 2 diabetes, NES was reported more frequently than BED, which, in turn, was less common than expected.

OBJECTIVE: The effectiveness of intentional weight loss in reducing cardiovascular disease (CVD) events in type 2 diabetes is unknown. This report describes 1-year changes in CVD risk factors in a trial designed to examine the long-term effects of an intensive lifestyle intervention on the incidence of major CVD events. RESEARCH DESIGN AND METHODS: This study consisted of a multicentered, randomized, controlled trial of 5,145 individuals with type 2 diabetes, aged 45-74 years, with BMI >25 kg/m2 (>27 kg/m2 if taking insulin). An intensive lifestyle intervention (ILI) involving group and individual meetings to achieve and maintain weight loss through decreased caloric intake and increased physical activity was compared with a diabetes support and education (DSE) condition. RESULTS: Participants assigned to ILI lost an average 8.6% of their initial weight vs. 0.7% in DSE group (P < 0.001). Mean fitness increased in ILI by 20.9 vs. 5.8% in DSE (P < 0.001). A greater proportion of ILI participants had reductions in diabetes, hypertension, and lipid-lowering medicines. Mean A1C dropped from 7.3 to 6.6% in ILI (P < 0.001) vs. from 7.3 to 7.2% in DSE. Systolic and diastolic pressure, triglycerides, HDL cholesterol, and urine albumin-to-creatinine ratio improved significantly more in ILI than DSE participants (all P < 0.01). CONCLUSIONS: At 1 year, ILI resulted in clinically significant weight loss in people with type 2 diabetes. This was associated with improved diabetes control and CVD risk factors and reduced medicine use in ILI versus DSE. Continued intervention and follow-up will determine whether these changes are maintained and will reduce CVD risk.
