RESUMO

BACKGROUND: Personalizing approaches to prevention and treatment of obesity will be a crucial aspect of precision health initiatives. However, in considering individual susceptibility to obesity, much remains to be learned about how to support healthy weight management in different population subgroups, environments and geographical locations. SUBJECTS/METHODS: The International Weight Control Registry (IWCR) has been launched to facilitate a deeper and broader understanding of the spectrum of factors contributing to success and challenges in weight loss and weight loss maintenance in individuals and across population groups. The IWCR registry aims to recruit, enroll and follow a diverse cohort of adults with varying rates of success in weight management. Data collection methods include questionnaires of demographic variables, weight history, and behavioral, cultural, economic, psychological, and environmental domains. A subset of participants will provide objective measures of physical activity, weight, and body composition along with detailed reports of dietary intake. Lastly, participants will be able to provide qualitative information in an unstructured format on additional topics they feel are relevant, and environmental data will be obtained from public sources based on participant zip code. CONCLUSIONS: The IWCR will be a resource for researchers to inform improvements in interventions for weight loss and weight loss maintenance in different countries, and to examine environmental and policy-level factors that affect weight management in different population groups. This large scale, multi-level approach aims to inform efforts to reduce the prevalence of obesity worldwide and its associated comorbidities and economic impacts.

RESUMO

BACKGROUND: Evaluating effects of different macronutrient diets in randomized trials requires well defined infrastructure and rigorous methods to ensure intervention fidelity and adherence. METHODS: This controlled feeding study comprised two phases. During a Run-in phase (14-15 weeks), study participants (18-50 years, BMI, ≥27 kg/m2) consumed a very-low-carbohydrate (VLC) diet, with home delivery of prepared meals, at an energy level to promote 15 ± 3% weight loss. During a Residential phase (13 weeks), participants resided at a conference center. They received a eucaloric VLC diet for three weeks and then were randomized to isocaloric test diets for 10 weeks: VLC (5% energy from carbohydrate, 77% from fat), high-carbohydrate (HC)-Starch (57%, 25%; including 20% energy from refined grains), or HC-Sugar (57%, 25%; including 20% sugar). Outcomes included measures of body composition and energy expenditure, chronic disease risk factors, and variables pertaining to physiological mechanisms. Six cores provided infrastructure for implementing standardized protocols: Recruitment, Diet and Meal Production, Participant Support, Assessments, Regulatory Affairs and Data Management, and Statistics. The first participants were enrolled in May 2018. Participants residing at the conference center at the start of the COVID-19 pandemic completed the study, with each core implementing mitigation plans. RESULTS: Before early shutdown, 77 participants were randomized, and 70 completed the trial (65% of planned completion). Process measures indicated integrity to protocols for weighing menu items, within narrow tolerance limits, and participant adherence, assessed by direct observation and continuous glucose monitoring. CONCLUSION: Available data will inform future research, albeit with less statistical power than originally planned.

RESUMO

Background: Alpha-1 antitrypsin deficiency (AATD) is the most common genetic risk factor for early-onset emphysema. However, AATD continues to be underrecognized and underdiagnosed. Provider awareness about AATD, concerns with testing costs, and limited understanding about therapeutic options contribute to its underdiagnosis. We hypothesized that provider education would improve awareness of AATD and improve screening. Objective: To evaluate the impact of a targeted provider education module on AATD screening. Methods: We developed a web-based education module to address barriers to screening for AATD, deployed the education module using the Medscape Education platform, assessed perceived healthcare provider confidence in AATD screening, and conducted a prospective pre and postintervention study of AATD testing practices at a high-volume academic outpatient subspecialty pulmonary clinic. Results: A total of 11,385 healthcare providers, including eight pulmonologists at our institution, completed the web-based education module. Confidence in identifying patients at high risk for AATD improved after completing the module ("not confident" in AATD screening was 7.7% postintervention compared with 19.4% preintervention). The rate of screening patients at high risk for AATD improved more than twofold (AATD screening rate 9.7% preintervention vs. 20.4% postintervention; P = 0.004). Among patients screened for AATD in our cohort, 27.2% had a genotype/phenotype or low alpha-1 antitrypsin concentration consistent with AATD. Conclusion: Targeted healthcare provider education can improve the confidence in testing for AATD. Improvements in provider confidence corresponded to improvements in AATD screening in a subspecialty pulmonary clinic. More than one-fourth of screening tests suggested AATD, underpinning the value of testing in high-risk individuals.

RESUMO

BACKGROUND: Many people with spinal cord injury (SCI) have limited access to tailored, readily available exercise resources. As a result, exercise remains an underutilized treatment strategy for improving health and function in people with SCI. The purpose of this study is to test the effectiveness of two remotely delivered exercise programs for people with SCI. METHODS: The Spinal Cord Injury Program in Exercise (SCIPE) study is a three-arm adaptive randomized controlled trial examining two 8-week teleexercise interventions: Movement-to-Music (M2M) and Standard Exercise Training (SET), compared to Attention Control (AC) in 327 adults with SCI. The primary outcome is change in physical activity level at post 8-week intervention. The study contains two interim analyses. The first interim analysis will assess feasibility metrics of the protocol after 36 participants complete the 8-week intervention period. The second interim analysis will examine two effectiveness comparisons: SET vs. AC and M2M vs AC, after 165 participants complete the intervention period. Early termination of the intervention arm(s) will take place when non-significant findings are found in the corresponding intervention(s). Incorporation of such interim analysis enhances trial efficiency by dropping the intervention(s) that deemed ineffective. It provides ethical benefits and allows allocation of additional resources to explore the effective intervention(s). DISCUSSION: Delivery of teleexercise programs may be an effective strategy for addressing transportation barrier to exercise resources and increasing physical activity level and quality of life in people with SCI. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03925077 . Registered trial name: Spinal Cord Injury Program in Exercise (SCIPE). Registered on April 23rd, 2019.

RESUMO

BACKGROUND: Access to comprehensive exercise and rehabilitation services for people with multiple sclerosis (MS) remains a major challenge, especially in rural, low-income areas. Hence, the Tele-Exercise and Multiple Sclerosis (TEAMS) study aims to provide patient-centered, coordinated care by implementing a 12-week complementary and alternative medicine (CAM) intervention for adults with MS. However, due to the societal impact of coronavirus disease (COVID-19) in mid-March 2020, the University of Alabama at Birmingham announced a limited business model halting all nonessential research requiring on-site visits, which includes the TEAMS study. OBJECTIVE: In compliance with the shelter-in-place policy and quarantine guidance, a modified testing and training protocol was developed to allow participants to continue the study. METHODS: The modified protocol, which replaces on-site data collection and training procedures, includes a teleassessment package (computer tablet, blood pressure cuff, hand dynamometer, mini disc cone, measuring tape, an 8" step, and a large-print 8" × 11" paper with ruler metrics and wall-safe tape) and a virtual meeting platform for synchronous interactive training between the therapist and the participant. The teleassessment measures include resting blood pressure and heart rate, grip strength, Five Times Sit to Stand, Timed Up & Go, and the Berg Balance Scale. The teletraining component includes 20 sessions of synchronous training sessions of dual tasking, yoga, and Pilates exercises designed and customized for a range of functional levels. Teletraining lasts 12 weeks and participants are instructed to continue exercising for a posttraining period of 9 months. RESULTS: The protocol modifications were supported with supplemental funding (from the Patient-Centered Outcomes Research Institute) and approved by the University Institutional Review Board for Human Use. At the time nonessential research visits were halted by the university, there were 759 people enrolled and baseline tested, accounting for 92.5% of our baseline testing completion target (N=820). Specifically, 325 participants completed the 12-week intervention and follow-up testing visits, and 289 participants needed to complete either the intervention or follow-up assessments. A modified analysis plan will include sensitivity analyses to ensure the robustness of the study results in the presence of uncertainty and protocol deviations. Study results are projected to be published in 2021. CONCLUSIONS: This modified remote teleassessment/teletraining protocol will impact a large number of participants with MS who would otherwise have been discontinued from the study.

RESUMO

BACKGROUND: Adherence to antiretroviral therapy (ART) is important to counter synergistic effects of HIV and hepatitis C (HCV) in patients living with coinfection. Predictors of ART nonadherence among patients living with HIV/HCV coinfection are not well established. This knowledge would be advantageous for clinicians and behavioral health specialists who provide care to patients living with HIV/HCV coinfection. OBJECTIVES: The purpose of this study was to assess prevalence and predictors of ART nonadherence in a sample of patients living with HIV/HCV coinfection who were actively in HIV clinical care. METHOD: A sample of patients living with HIV/HCV coinfection who received care at a university-affiliated HIV clinic (n = 137) between January 2013 and July 2017 were included in the study. Computerized patient-reported data or outcomes (PROs) and electronic medical record data of these respective patients were collected and analyzed. Binomial logistic regression was used to examine predictors of ART nonadherence. RESULTS: The prevalence of ART nonadherence was 31%. In multivariate analysis, African American ethnicity (OR = 3.28, CI 1.241-8.653, p = 0.017) and a higher number of alcoholic drinks per drinking day (OR = 1.31, CI 1.054-1.639, p = 0.015) were positively associated with ART nonadherence. CONCLUSIONS: Behavioral health providers are encouraged to incorporate alcohol use reduce interventions in HIV clinical settings to reduce ART nonadherence among patients living with HIV/HCV coinfection. Additionally, public health professionals and researchers, and clinicians are encouraged to use inductive methods to discover why ART nonadherence disproportionately impacts African American patients living with HIV/HCV coinfection and to develop approaches that are sensitive to those respective barriers.
