The state of the science on the health benefits of blueberries: a perspective.

Mounting evidence indicates that blueberry consumption is associated with a variety of health benefits. It has been suggested that regular consumption of blueberries can support and/or protect against cardiovascular disease and function, pre-diabetes and type 2 diabetes, and brain and cognitive function in individuals with health conditions and age-related decline. Further, mechanistic investigations highlight the role of blueberry anthocyanins in mediating these health benefits, in part through interactions with gut microbiota. Also, nutritional interventions with blueberries have demonstrated the ability to improve recovery following exercise-induced muscle damage, attributable to anti-inflammatory effects. Despite these advancements in blueberry health research, research gaps persist which affects the generalizability of findings from clinical trials. To evaluate the current state of knowledge and research gaps, a blueberry health roundtable with scientific experts convened in Washington, DC (December 6-7, 2022). Discussions centered around five research domains: cardiovascular health, pre-diabetes and diabetes, brain health and cognitive function, gut health, and exercise recovery. This article synthesizes the outcomes of a blueberry research roundtable discussion among researchers in these domains, offering insights into the health benefits of blueberries and delineating research gaps and future research directions.

Effect of Remotely Supervised Weight Loss and Exercise Training Versus Lifestyle Counseling on Cardiovascular Risk and Clinical Outcomes in Older Adults With Rheumatoid Arthritis: A Randomized Controlled Trial.

OBJECTIVE: To compare a remotely supervised weight loss and exercise intervention to lifestyle counseling for effects on cardiovascular disease risk, disease activity, and patient-reported outcomes in older patients with rheumatoid arthritis (RA) and overweight/obesity. METHODS: Twenty older (60-80 years), previously sedentary participants with seropositive RA and overweight/obesity were randomized to 16 weeks of either Supervised Weight loss and Exercise Training (SWET) or Counseling Health As Treatment (CHAT). The SWET group completed aerobic training (150 minutes/week moderate-to-vigorous intensity), resistance training (two days/week), and a hypocaloric diet (7% weight loss goal). The CHAT control group completed two lifestyle counseling sessions followed by monthly check-ins. The primary outcome was a composite metabolic syndrome z-score (MSSc) derived from fasting glucose, triglycerides, high density lipoprotein-cholesterol, minimal waist circumference, and mean arterial pressure. Secondary outcomes included RA disease activity and patient-reported outcomes. RESULTS: Both groups improved MSSc (absolute change -1.67 ± 0.64 in SWET; -1.34 ± 1.30 in CHAT; P < 0.01 for both groups) with no between-group difference. Compared with CHAT, SWET significantly improved body weight, fat mass, Disease Activity Score-28 C-reactive protein, and patient-reported physical health, physical function, mental health, and fatigue (P < 0.04 for all between-group comparisons). Based on canonical correlations for fat mass, cardiorespiratory fitness, and leg strength, component-specific effects were strongest for (1) weight loss improving MSSc, physical health, and mental health; (2) aerobic training improving physical function and fatigue; and (3) resistance training improving Disease Activity Score-28 C-reactive protein. CONCLUSION: In older patients with RA and overweight/obesity, 16 weeks of remotely supervised weight loss, aerobic training, and resistance training improve cardiometabolic health, patient-reported outcomes, and disease activity. Less intensive lifestyle counseling similarly improves cardiovascular disease risk profiles, suggesting an important role for integrative interventions in the routine clinical care of this at-risk RA population.

Nightshift imposes irregular lifestyle behaviors in police academy trainees.

Study Objective: Shiftwork increases risk for numerous chronic diseases, which is hypothesized to be linked to disruption of circadian timing of lifestyle behaviors. However, empirical data on timing of lifestyle behaviors in real-world shift workers are lacking. To address this, we characterized the regularity of timing of lifestyle behaviors in shift-working police trainees. Methods: Using a two-group observational study design (N = 18), we compared lifestyle behavior timing during 6 weeks of in-class training during dayshift, followed by 6 weeks of field-based training during either dayshift or nightshift. Lifestyle behavior timing, including sleep-wake patterns, physical activity, and meals, was captured using wearable activity trackers and mobile devices. The regularity of lifestyle behavior timing was quantified as an index score, which reflects day-to-day stability on a 24-hour time scale: Sleep Regularity Index, Physical Activity Regularity Index, and Mealtime Regularity Index. Logistic regression was applied to these indices to develop a composite score, termed the Behavior Regularity Index (BRI). Results: Transitioning from dayshift to nightshift significantly worsened the BRI, relative to maintaining a dayshift schedule. Specifically, nightshift led to more irregular sleep-wake timing and meal timing; physical activity timing was not impacted. In contrast, maintaining a dayshift schedule did not impact regularity indices. Conclusions: Nightshift imposed irregular timing of lifestyle behaviors, which is consistent with the hypothesis that circadian disruption contributes to chronic disease risk in shift workers. How to mitigate the negative impact of shiftwork on human health as mediated by irregular timing of sleep-wake patterns and meals deserves exploration.

The effects of a 6-month weight loss intervention on physical function and serum biomarkers in older adults with and without osteoarthritis.

Objective: To examine the effects of a 6-month weight loss intervention on physical function, inflammatory biomarkers, and metabolic biomarkers in both those with and without osteoarthritis (OA). Design: 59 individuals ≥60 years old with obesity and a functional impairment were enrolled into this IRB approved clinical trial and randomized into one of two 6-month weight loss arms: a higher protein hypocaloric diet or a standard protein hypocaloric diet. All participants were prescribed individualized 500-kcal daily-deficit diets, with a goal of 10% weight loss. Additionally, participants participated in three, low-intensity, exercise sessions per week. Physical function, serum biomarkers and body composition data were assessed at the baseline and 6-month timepoints. Statistical analyses assessed the relationships between biomarkers, physical function, body composition, and OA status as a result of the intervention. Results: No group effects of dietary intervention were detected on any outcome measures (multiple p â€‹> â€‹0.05). During the 6-month trial, participants lost 6.2 â€‹± â€‹4.0% of their bodyweight (p â€‹< â€‹0.0001) and experienced improved physical function on the Short-Performance-Physical-Battery (p â€‹< â€‹0.0001), 8-foot-up-and-go (p â€‹< â€‹0.0001), and time to complete 10-chair-stands (p â€‹< â€‹0.0001). Adiponectin concentrations (p â€‹= â€‹0.0480) were elevated, and cartilage oligomeric matrix protein (COMP) concentrations (p â€‹< â€‹0.0001) were reduced; further analysis revealed that reductions in serum COMP concentrations were greater in OA-negative individuals. Conclusions: These results suggest that weight loss in older adults with and without OA may provide a protective effect to cartilage and OA. In particular, OA-negative individuals may be able to mitigate changes associated with OA through weight loss.

Nightshift Imposes Irregular Lifestyle Behaviors in Police Academy Trainees.

Feasibility of Virtually Delivering Functional Fitness Assessments and a Fitness Training Program in Community-Dwelling Older Adults.

The COVID-19 pandemic limited older adults' access to preventative and diagnostic services and negatively affected accessibility to age-appropriate exercise programs. The purpose of this study was to assess the feasibility of conducting guided virtual functional fitness assessments before and after participation in an 8-week virtual, live fitness program (Vivo) designed for older adults. It was hypothesized there would be no significant difference between in-person and virtual functional fitness assessments and function would improve following the program. Thirteen community-dwelling older adults were recruited, screened, and randomly assigned to in-person-first or virtual-first fitness assessment groups. Validated assessments were delivered using standardized scripts by trained researchers and included Short Physical Performance Battery (SPPB) balance, a 30 s Chair Stand Test, 8 Foot Up-and-Go Test, 30 s Arm Curl Test, and 2 min Step Test. The eight-week, twice-a-week live virtual fitness program involved cardiovascular, balance, agility, Dual-Task, and strength training. Results showed no significant differences between all but one assessment measures, and several measures improved following the eight-week program. Fidelity checks demonstrated the high fidelity of program delivery. These findings illustrate that virtual assessments can be a feasible method to measure functional fitness in community-dwelling older adults.

Dysphagia in Older Adults is Associated With Food Insecurity and Being Homebound.

Objective: Our aim was to evaluate relationships between swallowing difficulty (dysphagia) and social determinants of health (SDOH) in older adults ≥65 years. Method: Cross-sectional analyses were performed in community-dwelling Medicare beneficiaries from the National Health & Aging Trends Study (NHATS). The primary exposure was self-reported difficulty chewing/swallowing in the prior month. Dependent measures included a variety of SDOH outcomes (e.g., food insecurity [FI]). Weighted logistic regression models were estimated to determine associations between dysphagia and SDOH outcomes. Results: Of 4041 participants, 428 (10.6%) self-reported dysphagia. In the adjusted model, dysphagia was associated with significantly increased odds for FI (odds ratio [OR] = 1.48, 95% confidence interval [CI] = 1.06, 2.07, p = .023) and being homebound (OR = 1.32, 95% CI = 1.13, 1.55, p= < .001). Discussion: Older adults with dysphagia had increased odds of FI and being homebound. These associations have implications for health-promoting interventions at the individual and policy levels in older adults.

Self-Reported Dysphagia and Psychosocial Health Among Community-Dwelling Older Adults: Results of a National Study.

BACKGROUND: The risk of dysphagia increases with age, affecting up to 33% of adults over the age of 65. Older adults with dysphagia are at increased risk for negative physical health outcomes such as aspiration pneumonia and death. However, the relationship between dysphagia and psychosocial health is uncertain in this population. OBJECTIVE: We aimed to assess the associations between dysphagia and psychosocial health among older adults (≥ 65) with self-reported dysphagia. DESIGN: We performed a cross-sectional assessment of the National Health and Aging Trends Study (NHATS) conducted in 2019. MAIN MEASURES: Weighted logistic and linear regression models were used to assess the relationship between self-reported dysphagia and psychosocial health using established patient-reported outcome measures including those for depression, anxiety, and social isolation previously used in NHATS analyses, while adjusting for demographics, comorbid conditions, and risk factors for dysphagia identified by purposeful selection. KEY RESULTS: Among the 4041 adults in this cohort, almost half (40%) were between 70 and 74 years old, more than half were female (55%), and a significantly higher proportion were White, non-Hispanic respondents (78.1%, p < 0.01) compared with other races and ethnicities. There were 428 (10.5%) respondents reporting dysphagia symptoms within the previous month. In the multivariable model, dysphagia was associated with significantly increased odds of anxiety (OR 1.33 [1.06, 1.67]) and a significantly decreased sense of well-being (coefficient - 1.10 [- 1.66, - 0.54]), but no association was detected for social isolation. CONCLUSIONS: When accounting for factors associated with underlying physical health status, self-reported dysphagia is independently associated with negative psychosocial health and warrants attention by healthcare providers. Future studies should aim to identify causal factors and the extent to which interventions may mitigate these factors.

Prevalence and socio-economic determinates of food insecurity in Veterans: findings from National Health and Nutrition Examination Survey.

OBJECTIVE: To determine predictors of the association between being a Veteran and adult food security, as well as to examine the relation of potential covariates to this relationship. DESIGN: Data collected during 2011-2012, 2013-2014 and 2015-2016 National Health and Nutrition Examination Survey (NHANES) were pooled for analyses. Veterans (self-reported) were matched to non-Veterans on age, race/ethnicity, sex and education. Adjusted logistic regression was used to determine the odds of Veterans having high food security v. the combination of marginal, low and very low food security compared with non-Veterans. SETTING: 2011-2012, 2013-2014 and 2015-2016 NHANES. PARTICIPANTS: 1227 Veterans; 2432 non-Veterans. RESULTS: Veteran status had no effect on the proportion of food insecurities between Veterans and non-Veterans reporting high (Veterans v. non-Veteran: 79 % v. 80 %), marginal (9 % v. 8 %), low (5 % v. 6 %) and very low (8 % v. 6 %) food security (P = 0·11). However, after controlling for covariates, Veterans tended to be less likely to have high food security (OR: 0·82 (95 % CI 0·66, 1·02), P = 0·07). Further, non-Hispanic White Veterans (OR: 0·72 (95 % CI 0·55, 0·95), P = 0·02) and Veterans completing some college (OR: 0·71 (95 % CI 0·50, 0·99), P < 0·05) were significantly less likely to experience high food security compared with non-Veterans. CONCLUSION: This study supports previous research findings that after controlling for covariates, Veterans tend to be less likely to have high food security. It also highlights ethnicity and level of education as important socio-economic determinates of food security status in Veterans.

Key Strategies for Optimizing Pediatric Perioperative Nutrition-Insight from a Multidisciplinary Expert Panel.

Adequate nutrition is an essential factor in healing and immune support in pediatric patients undergoing surgery, but its importance in this setting is not consistently recognized. Standardized institutional nutrition protocols are rarely available, and some clinicians may be unaware of the importance of assessing and optimizing nutritional status. Moreover, some clinicians may be unaware of updated recommendations that call for limited perioperative fasting. Enhanced recovery protocols have been used in adult patients undergoing surgery to ensure consistent attention to nutrition and other support strategies in adult patients before and after surgery, and these are now under evaluation for use in pediatric patients as well. To support better adoption of ideal nutrition delivery, a multidisciplinary panel of experts in the fields of pediatric anesthesiology, surgery, gastroenterology, cardiology, nutrition, and research have gathered and reviewed current evidence and best practices to support nutrition goals in this setting.

Remotely Supervised Weight Loss and Exercise Training to Improve Rheumatoid Arthritis Cardiovascular Risk: Rationale and Design of the Supervised Weight Loss Plus Exercise Training-Rheumatoid Arthritis Trial.

Patients with rheumatoid arthritis (RA) remain at an increased risk for cardiovascular disease (CVD) and mortality. RA CVD results from a combination of traditional risk factors and RA-related systemic inflammation. One hypothetical means of improving overall RA CVD risk is through reduction of excess body weight and increased physical activity. Together, weight loss and physical activity can improve traditional cardiometabolic health through fat mass loss, while also improving skeletal muscle health. Additionally, disease-related CVD risk may improve as both fat mass loss and exercise reduce systemic inflammation. To explore this hypothesis, 26 older persons with RA and overweight/obesity will be randomized to 16 weeks of a usual care control arm or to a remotely Supervised Weight Loss Plus Exercise Training (SWET) program. A caloric restriction diet (targeting 7% weight loss) will occur via a dietitian-led intervention, with weekly weigh-ins and group support sessions. Exercise training will consist of both aerobic training (150 minutes/week moderate-to-vigorous exercise) and resistance training (twice weekly). The SWET remote program will be delivered via a combination of video conference, the study YouTube channel, and study mobile applications. The primary cardiometabolic outcome is the metabolic syndrome Z score, calculated from blood pressure, waist circumference, high-density lipoprotein cholesterol, triglycerides, and glucose. RA-specific CVD risk will be assessed with measures of systemic inflammation, disease activity, patient-reported outcomes, and immune cell function. The SWET-RA trial will be the first to assess whether a remotely supervised, combined lifestyle intervention improves cardiometabolic health in an at-risk population of older individuals with RA and overweight/obesity.

Preoperative dysphagia risk in community-dwelling adults aged ≥50 years: Prevalence and risk factors.

BACKGROUND: Preoperative dysphagia screening is rare. The purpose of this study was to assess the prevalence and potential risk factors of preoperative dysphagia risk in adults preparing for surgery. METHODS: The Eating Assessment Tool (EAT-10), Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF), and Sarcopenia Screening Tool (SARC-F) were self-administered in adults preparing for surgery to identify dysphagia, malnutrition, and sarcopenia risk, respectively. Other variables collected include clinical demographics, fall risk, and surgical history associated with increased dysphagia risk. Descriptive summary statistics, univariate analysis, and logistic regression were performed as appropriate. RESULTS: The median age was 69 years and preoperative dysphagia risk was 9.6%. Among 357 patients completing both EAT-10 and PG-SGA SF or SARC-F, 7.3% had preoperative dysphagia and malnutrition risk and 7.2% had preoperative dysphagia and sarcopenia risk. Preoperative dysphagia risk was 2.7 times greater in those with prior surgical history associated with increased risk of dysphagia, 2.2 times higher in women, and almost twice as high in Black patients and patients with fall risk. Logistic regression revealed significant odds ratios (ORs) for prior surgical history associated with increased risk of dysphagia (OR, 2.95; 95% CI, 1.62-5.40) and male sex (OR, 0.52; 95% CI, 0.29-0.94), and a significant relationship between preoperative dysphagia and malnutrition risk (OR, 4.56; 95% CI, 2.02-10.28) when controlling for clinical variables. CONCLUSION: The high prevalence of dysphagia risk alone and in combination with malnutrition and sarcopenia risk in community-dwelling adults underscores the need for standardized preoperative screening and optimization prior to surgery.

Energy Metabolism in Gynecological Cancers: A Scoping Review.

Determining energy requirements is vital for optimizing nutrition interventions in pro-catabolic conditions such as cancer. Gynecological cancer encompasses the most common malignancies in women, yet there is a paucity of research on its metabolic implications. The aim of this review was to explore the literature related to energy metabolism in gynecological cancers. We were particularly interested in exploring the prevalence of energy metabolism abnormalities, methodological approaches used to assess energy metabolism, and clinical implications of inaccurately estimating energy needs. A search strategy was conducted from inception to 27 July 2021. Studies investigating energy metabolism using accurate techniques in adults with any stage of gynecological cancer and the type of treatment were considered. Of the 874 articles screened for eligibility, five studies were included. The definition of energy metabolism abnormalities varied among studies. Considering this limitation, four of the five studies reported hypermetabolism. One of these studies found that hypermetabolism was more prevalent in ovarian compared to cervical cancer. Of the included studies, one reported normometabolism at the group level; individual-level values were not reported. One of the studies reported hypermetabolism pre- and post-treatment, but normometabolism when re-assessed two years post-treatment. No studies explored clinical implications of inaccurately estimating energy needs. Overall, commonly used equations may not accurately predict energy expenditure in gynecological cancers, which can profoundly impact nutritional assessment and intervention.

Mediterranean diet scoring systems: understanding the evolution and applications for Mediterranean and non-Mediterranean countries.

The Mediterranean diet (MedD) is a flexible dietary pattern which has such variability that has led to inconsistencies in definitions and assessment. The purpose of this narrative review is to evaluate scoring systems in a cultural and geographic context, from Mediterranean and non-Mediterranean countries, for comparison and application. The early MedD scoring systems (i.e. Trichopoulou's MedD Scale (T-MDS) and alternative MedD Scale (aMed)) are widely applied throughout the world but use population-specific median cut-offs which limit interpretation and cross-study comparisons. The T-MDS and aMed also do not account for non-traditional MedD foods which are consumed in greater quantities than when the scoring systems were developed. Scoring systems developed after the MedD pyramid publication in 2011 have generally used these recommendations as a basis for food group intake cut-offs, incorporating more foods/food groups as negative components, and some have included dietary and lifestyle behaviours. The different approaches to MedD assessment have created much variability in the foods/food group components included in scoring systems. Assessments that include dietary and lifestyle behaviours may reflect the nutrition transition occurring in Mediterranean countries and better guide clinical intervention approaches. While the new scoring systems are theorised to better capture MedD adherence and behaviours, comparisons are sparse in the literature and none exists outside of Europe. Consensus on food and dietary behaviours to include as well as the methodology for assigning points in MedD scoring systems is needed to advance our understanding of MedD and health relationships to promote public health messaging and clinical application.

Diet quality and exercise in older veterans with PTSD: a pilot study.

Older veterans with posttraumatic stress disorder (PTSD) are at increased risk of obesity and cardiometabolic disease. Physical activity and healthy eating are two behaviors that impact health, functional independence, and disease risk in later life, yet few studies have examined the relationship between PTSD and diet quality. This secondary analysis aimed to: (a) characterize the diet quality of older veterans with PTSD in comparison to U.S. dietary guidelines and (b) explore if participation in a supervised exercise intervention spurred simultaneous changes in dietary behavior. Diet quality was assessed with the Dietary Screener Questionnaire (DSQ), which measures daily intake of fiber, calcium, added sugar, whole grain, dairy, and fruits/vegetables/legumes. The sample included 54 military veterans ≥ 60 years old with PTSD who participated in a randomized controlled pilot trial comparing 12 weeks of supervised exercise (n = 36) to wait-list usual care (n = 18). The DSQ was administered at baseline and 12 weeks. Consumption of added sugar exceeded U.S. dietary guideline recommendations and consumption of whole grains, fruits/vegetables/legumes, fiber, calcium, and dairy fell short. Participation in the supervised exercise intervention was not associated with changes in diet quality. Results revealed that the diet quality of older veterans with PTSD is poor, and while the exercise intervention improved health through exercise, it did not make veterans any more likely to adopt a more healthful diet. Interventions targeting diet, or diet + exercise, are needed to manage the increased risk of obesity and cardiometabolic disease present in older veterans with PTSD.

Older veterans with posttraumatic stress disorder (PTSD) are at risk for several physical health conditions that reduce their quality of life. Physical activity and healthy eating are important behaviors for promoting good health and physical function in later life. The purpose of this study was to examine the diet quality of older veterans with PTSD and explore whether a program designed to increase exercise also improved diet. Diet quality was measured with a self-report survey, the Dietary Screener Questionnaire (DSQ), which measures daily intake of fiber, calcium, added sugar, whole grain, dairy, and fruits/vegetables/legumes. Study participants were 54 military veterans age 60 years and older with PTSD who participated in a randomized controlled pilot trial comparing 12 weeks of supervised exercise to wait-list usual care. The DSQ was administered at baseline and 12 weeks post intervention. Results show that older veterans with PTSD have overall poor diet quality that included consuming too much added sugar and not enough whole grains, fruits/vegetables/legumes, fiber, calcium, and dairy. Participation in the supervised exercise did not lead to simultaneous diet quality changes over 12 weeks. This study shows that diet quality is poor in older veterans with PTSD and future programs are needed to target this health behavior.

Navigating the Doctor of Nursing Practice project within an academic practice partnership.

ABSTRACT: The Doctor of Nursing Practice (DNP) curriculum was initially developed in 2004. The DNP degree is a practice doctorate, which educates nurses to the highest level of clinical nursing practice. DNP students must complete a scholarly project in accordance with the American Association of Colleges of Nursing (AACN) guidelines. The project is an opportunity for the student to integrate skills into practice and demonstrate principles of advanced nursing practice. The AACN provides recommendations for the DNP project, but much confusion regarding the context and implementation of the project still exists. At one academic health sciences center, DNP project students often complete their projects within academic practice partnerships. Such partnerships are encouraged by the AACN. Several DNP quality improvement (QI) projects were submitted a hospital's interdisciplinary quality week event. Upon review, some of the abstracts were found to contain aspects of research. This finding prompted the review of all DNP project processes to standardize methods for faculty, students, the University, and the academic practice partner.

Association between Dysphagia and Surgical Outcomes across the Continuum of Frailty.

This study examined the relationship between dysphagia and adverse outcomes across frailty conditions among surgical patients ≥50 years of age. A retrospective cohort analysis of surgical hospitalizations in the Healthcare Cost and Utilization Project's National Inpatient Sample among patients ≥50 years of age undergoing intermediate/high risk surgery not involving the larynx, pharynx, or esophagus. Of 3,298,835 weighted surgical hospitalizations, dysphagia occurred in 1.2% of all hospitalizations and was higher in frail patients ranging from 5.4% to 11.7%. Dysphagia was associated with greater length of stay, higher total costs, increased non-routine discharges, and increased medical/surgical complications among both frail and non-frail patients. Dysphagia may be an independent risk factor for poor postoperative outcomes among surgical patients ≥50 years of age across frailty conditions and is an important consideration for providers seeking to reduce risk in vulnerable surgical populations.

Rationale and Design for a Higher (Dairy) Protein Weight Loss Intervention That Promotes Muscle Quality and Bone Health in Older Adults with Obesity: A Randomized, Controlled Pilot Study.

In contrast to recommendations for young and middle-aged adults, intentional weight loss among older adults remains controversial and is inconsistently advised. Recent research suggests that a higher protein diet can mitigate loss of lean mass during periods of intentional weight loss among older adults with obesity; however, the effects of intentional weight loss on skeletal muscle and bone are not fully understood. The Dairy in the Diet Yields New Approaches for Muscle Optimization (DDYNAMO) trial is a 6-month, randomized, controlled pilot study assessing the effects of combining regular, generous intakes of high quality protein (30 g/meal; primarily from dairy) with caloric restriction (-500kcal/d) and low-intensity resistance exercise (30 min/3 times per week) on muscle quality, muscle composition, bone mineral density in men and women aged ≥60 years with obesity and mild to moderate functional impairment (Short Physical Performance Battery [SPPB] score ≥4 to ≤10). Participants will be re-assessed at 18 months to evaluate weight maintenance, bone mineral density, physical function, and other secondary measures. ClinicalTrials.gov Identifier: NCT02437643.
