Project description:OBJECTIVES:To describe recruitment of Latinas in a randomized clinical trial conducted within 2 health care organizations. METHODS:The study relied on project-initiated telephone calls as part of a multifaceted recruitment approach. Chi-square and t tests were conducted to compare participants and nonparticipants on a number of variables. RESULTS:From 4045 telephone contacts, 280 Latinas agreed to participate. Most were ineligible due to non-Latino ethnicity (89%). Of eligible candidates, 61% took part. Few significant differences were found on participant vs nonparticipant characteristics. CONCLUSIONS:Using appropriate recruitment procedures, a representative sample of Latinas can be obtained.

Project description:BACKGROUND:Fruit and vegetable (F&V) intake can reduce risks for chronic disease, but is much lower than recommended amounts in most Western populations, especially for those with low income levels. Rigorous research is needed on practical, cost-effective interventions that address environmental as well as personal determinants of F&V intake. This paper presents the results of a cluster randomized controlled trial evaluating the efficacy of 'Live Well, Viva Bien' (LWVB), a multicomponent intervention that included discount, mobile fresh F&V markets in conjunction with nutrition education. METHODS:Fifteen subsidized housing sites in Providence County, Rhode Island (8 intervention and 7 control sites) were randomized using a random number generator. Of these, nine housed elderly and/or disabled residents and six housed families. A total of 1597 adult housing site residents (treatment n = 837; control n = 760) were enrolled (73% women, 54% Hispanic, 17% black, Mean age 54 years). A year-long multicomponent intervention including mobile F&V markets plus nutrition education (e.g. campaigns, DVDs, newsletters, recipes, and chef demonstrations) was implemented at intervention sites. Physical activity and stress interventions were implemented at control sites. Follow-up occurred at 6 and 12 months. The main outcome measure was F&V consumption measured by National Cancer Institute's 'Eating at America's Table All Day Screener'. RESULTS:From baseline to 12 months, the intervention group increased total F&V intake by 0.44 cups with the control group decreasing intake by 0.08 cups (p < .02). Results also showed an increased frequency of F&V eating behaviors compared to the control group (p < .01). There was a clear dose response effect of the F&V markets with participants who reported attending all or most of the markets increasing F&V intake by 2.1 cups and 0.86 cups, respectively compared with less than half cup increases for lower levels of market attendance (p < .05). Use of the DVDs, recipes and taste-testings was also associated with greater increases in F&V intake; however, use of other educational components was not. CONCLUSIONS:LWVB is the first cluster, randomized controlled trial to demonstrate the efficacy of year-round F&V markets on improving F&V intake for low-income adults, which provides an evidence-base to bolster the mission of mobile produce markets. Further, the results more broadly support investment in environmental changes to alleviate disparities in F&V consumption and diet-related health inequities.

Project description:ImportancePediatric-onset multiple sclerosis (PoMS) is associated with significant cognitive and physical disability. Whether this disability translates into differences in educational achievements and earnings is unknown.ObjectiveTo evaluate the association between PoMS and educational level and income throughout adulthood.Design, setting, and participantsA prospective register-based cohort study of individuals with PoMS and a population-based matched reference cohort was conducted using nationwide microdata from linked registers in Sweden from January 1, 1990, to December 31, 2016; analyses were completed from May 1, 2019, to September 1, 2020. Of 772 persons with PoMS identified in the Swedish MS registry, 485 had an onset during the period from 1980 to 2014 and had socioeconomic data available. The general population reference cohort without multiple sclerosis (MS) (n = 4850) was randomly selected from the full Swedish population, matched 10:1 on age, sex, and country of birth.ExposurePediatric-onset MS, diagnosed by a neurologist, with onset before 18 years of age.Main outcomes and measuresHighest educational level (elementary school, high school, or university) was assessed using logistic regression. Income, measured as the mean annual earnings from paid work in US dollars, was compared using Tobit models, and net annual sickness absence and disability pension days were compared using zero-inflated negative binomial regression. Earnings and days receiving disability benefits were compared within 4 age periods (19-24, 25-34, 35-44, and 45-54 years).ResultsThe median age of the cohort with PoMS (n = 485) and the matched reference cohort (n = 4850) in 2016 was 32 years (interquartile range, 26-40 years), and most participants were women (348 [71.8%] in the PoMS cohort and 3480 [71.8%] in the matched reference cohort). Persons with PoMS were less likely than persons in the matched reference cohort to attend university (odds ratio, 0.80 [95% CI, 0.66-0.97]) and had significantly lower annual earnings than the reference cohort, ranging from -$1618 (95% CI, -$2558 to -$678) in the youngest age period to -$10 683 (95% CI, -$18 187 to -$3178) in the eldest. Persons with PoMS received higher rates of disability benefits, as sickness absence days in the youngest age period (rate ratio, 3.06 [95% CI, 2.08-4.52]) and disability pension days in the oldest age period (rate ratio, 1.43 [95% CI, 1.11-1.85]).Conclusions and relevanceThis study suggests that having PoMS is associated with less educational achievement, lower earnings, and greater use of disability benefits throughout the working-age life span. As adults, persons with PoMS never earned as much as their counterparts without MS, and they exhibited a heavier reliance on disability benefits.

Project description:AIMS/HYPOTHESIS:We conducted an analysis of data collected during the Veterans Affairs Diabetes Trial (VADT) and the follow-up study (VADT-F) to determine whether intensive (INT) compared with standard (STD) glycaemic control during the VADT resulted in better long-term kidney outcomes. METHODS:VADT randomly assigned 1791 veterans from 20 Veterans Affairs (VA) medical centres who had type 2 diabetes mellitus and a mean HbA1c of 9.4 ± 2% (79.2 mmol/mol) at baseline to receive either INT or STD glucose control for a median of 5.6 years (randomisation December 2000 to May 2003; intervention ending in May 2008). After the trial, participants received routine care through their own physicians within the VA. This is an interim analysis of the VADT-F (June 2008 to December 2013). We collected data using VA and National databases and report renal outcomes based on serum creatinine, eGFR and urine albumin to creatinine ratio (ACR) in 1033 people who provided informed consent to participate in the VADT-F. RESULTS:By the end of the VADT-F, significantly more people who received INT treatment during the VADT maintained an eGFR >60 ml min-1 1.73 m-2 (OR 1.34 [95% CI 1.05, 1.71], p = 0.02). This benefit was most evident in those who were classified as at moderate risk (INT vs STD, RR 1.3, p = 0.03) or high risk (RR 2.3, p = 0.04) of chronic kidney disease on the Kidney Disease Improving Global Outcomes (KDIGO-CKD) at the beginning of VADT. At the end of VADT-F, significantly more people from the INT group improved to a low KDIGO risk category (RR 6.1, p = 0.002). During the VADT-F there were no significant differences between INT and STD for average HbA1c, blood pressure or lipid levels. CONCLUSIONS/INTERPRETATION:After just over 11 years of follow-up, there was a 34% greater odds of maintaining an eGFR of >60 ml min-1 1.73 m-2 and of improving the KDIGO category in individuals with type 2 diabetes who had received INT for a median of 5.6 years.

Project description:To investigate long-term metformin adherence in the Diabetes Prevention Program Outcomes Study (DPPOS) by examining: (1) predictors of long-term adherence to study metformin and (2) whether metformin adherence was associated with incident type 2 diabetes. DPPOS was an open-label continuation of the randomized clinical trial (Diabetes Prevention Program (DPP)) in which eligible participants randomized to the metformin group were offered study metformin and followed over 11 years. A brief structured adherence interview was administered semiannually. Metformin adherence was assessed by pill counts. Predictors of metformin adherence were examined in multivariate regression models. Incident diabetes associated with metformin adherence and other variables was assessed in Cox proportional hazards models. Of 868 participants eligible to continue taking study metformin, 664 (76%) took at least some metformin over 11 years, with 478 of them reporting problems with adherence. DPPOS cumulative adherence showed significant associations of higher adherence (≥80%) with early adherence at 3 months in DPP (p<0.001) and lower depression scores during DPPOS (p<0.001); significant differences were also seen by race/ethnicity (p<0.004). Predicting adherence by multivariate modeling showed odds of adherence significantly lower for Black participants and for participants reporting more than one barrier. Odds for adherence were significantly higher for those adherent early in DPP and those reporting at least one planned strategy to improve adherence. Higher metformin adherence was significantly associated with a lower diabetes risk (p=0.04), even after adjustment for demographic variables, depression, and anxiety scores. In this long-term diabetes prevention study, early metformin adherence and planned strategies to promote adherence improved long-term adherence over 11 years; higher adherence to metformin was related to lower diabetes incidence. Incorporating strategies to promote adherence when initially prescribing metformin and counseling to support adherence over time are warranted.

Project description:As multiple myeloma (MM) treatments evolve, frequent updates are required to monitor the long-term effect of changes in approach. Traditionally, MM is considered an incurable disease, with most patients eventually relapsing. However, improvements in treatments has raised the possibility that MM might be functionally curable. To examine improvements in long-term survival, we followed 4329 patients with newly diagnosed MM treated with autologous stem cell transplantation (ASCT) at the University of Arkansas for Medical Sciences from 1989 through 2018. Overall survival (OS) and progression-free survival (PFS) were evaluated using Kaplan-Meier analysis, Cox proportional hazards models, relative survival analysis, and cure modeling among different time periods, risk groups, and demographic traits. Steady improvements in OS were found, with patients treated in 2014 or later having superior OS (hazard ratio, 0.35; 95% confidence interval [CI], 0.27-0.45) and reduced excess risk for MM death (relative excess risk, 0.30; 95% CI, 0.22-0.41) compared with patients treated in 1997 or earlier. Patients treated during intervening time periods often had intermediate survival, but trends in OS, PFS, and landmarked analyses were inconsistent. Cure models support the potential for cure, ranging from 6.3% to 31.3%, depending on the year of treatment, with 10.0% to 18.6% of patients achieving their normal life expectancy across multiple periods. There was some evidence of reductions in early mortality within 3 years of diagnosis, longer complete response (CR) duration, and reductions in relapse after achieving CR. However, results differed depending on age, risk group, and cytogenetic characteristics.

Project description:Importance:Autologous hematopoietic stem cell transplantation (AHSCT) may be effective in aggressive forms of multiple sclerosis (MS) that fail to respond to standard therapies. Objective:To evaluate the long-term outcomes in patients who underwent AHSCT for the treatment of MS in a large multicenter cohort. Design, Setting, and Participants:Data were obtained in a multicenter, observational, retrospective cohort study. Eligibility criteria were receipt of AHSCT for the treatment of MS between January 1995 and December 2006 and the availability of a prespecified minimum data set comprising the disease subtype at baseline; the Expanded Disability Status Scale (EDSS) score at baseline; information on the administered conditioning regimen and graft manipulation; and at least 1 follow-up visit or report after transplant. The last patient visit was on July 1, 2012. To avoid bias, all eligible patients were included in the analysis regardless of their duration of follow-up. Data analysis was conducted from September 1, 2014 to April 27, 2015. Exposures:Demographic, disease-related, and treatment-related exposures were considered variables of interest, including age, disease subtype, baseline EDSS score, number of previous disease-modifying treatments, and intensity of the conditioning regimen. Main Outcomes and Measures:The primary outcomes were MS progression-free survival and overall survival. The probabilities of progression-free survival and overall survival were calculated using Kaplan-Meier survival curves and multivariable Cox proportional hazards regression analysis models. Results:Valid data were obtained from 25 centers in 13 countries for 281 evaluable patients, with median follow-up of 6.6 years (range, 0.2-16 years). Seventy-eight percent (218 of 281) of patients had progressive forms of MS. The median EDSS score before mobilization of peripheral blood stem cells was 6.5 (range, 1.5-9). Eight deaths (2.8%; 95% CI, 1.0%-4.9%) were reported within 100 days of transplant and were considered transplant-related mortality. The 5-year probability of progression-free survival as assessed by the EDSS score was 46% (95% CI, 42%-54%), and overall survival was 93% (95% CI, 89%-96%) at 5 years. Factors associated with neurological progression after transplant were older age (hazard ratio [HR], 1.03; 95% CI, 1.00-1.05), progressive vs relapsing form of MS (HR, 2.33; 95% CI, 1.27-4.28), and more than 2 previous disease-modifying therapies (HR, 1.65; 95% CI, 1.10-2.47). Higher baseline EDSS score was associated with worse overall survival (HR, 2.03; 95% CI, 1.40-2.95). Conclusions and Relevance:In this observational study of patients with MS treated with AHSCT, almost half of them remained free from neurological progression for 5 years after transplant. Younger age, relapsing form of MS, fewer prior immunotherapies, and lower baseline EDSS score were factors associated with better outcomes. The results support the rationale for further randomized clinical trials of AHSCT for the treatment of MS.
