Introduction Supporting patients' decision making about clinical trials may enhance trial participation. To date, few theory-based interventions have been tested to address this issue. Objectives In this study, we aimed to evaluate the effect of a multimedia psychoeducation (MP) intervention, relative to print education (PE), on patients' decision support needs and attitudes about clinical trials. Methods Patients with cancer who were eligible for participation in an National Cancer Institute (NCI) therapeutic cancer clinical trial were recruited through the nationwide University of Rochester Cancer Center (URCC) NCI Community Oncology Research Program (NCORP) from 2014- 2016 and randomized to the MP or PE intervention. Assessments at baseline (before intervention), post-intervention, and at a two-month follow- up included patients' decision support needs, attitudes regarding clinical trials, and clinical trial participation. Results We recruited 418 cancer patients (ages 26-89, various cancer types). Relative to the PE condition, the MP condition did not significantly affect decision support needs. However, patients in the MP condition reported significantly more positive attitudes about clinical trials and were more likely to participate in a clinical trial than those in the PE condition (69% vs. 62%, p=0.01). Furthermore, improvement in attitudes about clinical trials significantly mediated the effect of the intervention on participation in clinical trials. Conclusions The MP intervention was able to improve patient attitudes toward clinical trials when compared with PE, and this improvement led to increased rates of participation in trials. The MP intervention could be disseminated to improve attitudes about clinical trials among cancer patients

United States Veterans are at excess risk for type 2 diabetes, but population differentials in risk have not been characterized. We determined risk of type 2 diabetes in relation to prediabetes and dyslipidemic profiles in Veterans at the VA New York Harbor (VA NYHHS) during 2004-2014. Prediabetes was based on American Diabetes Association hemoglobin A1c (HbA1c) testing cut-points, one of several possible criteria used to define prediabetes. We evaluated transition to type 2 diabetes in 4,297 normoglycemic Veterans and 7,060 Veterans with prediabetes. Cox proportional hazards regression was used to relate HbA1c levels, lipid profiles, demographic, anthropometric and comorbid cardiovascular factors to incident diabetes (Hazard Ratio [HR] and 95% confidence intervals). Compared to normoglycemic Veterans (HbA1c: 5.0-5.6%; 31-38 mmol/mol), risks for diabetes were >2-fold in the moderate prediabetes risk group (HbA1c: 5.7-5.9%; 39-41 mmol/mol) (HR 2.37 [1.98-2.85]) and >5-fold in the high risk prediabetes group (HbA1c: 6.0-6.4%; 42-46 mmol/mol) (HR 5.59 [4.75-6.58]). Risks for diabetes were increased with elevated VLDL (≥40mg/dl; HR 1.31 [1.09-1.58]) and TG/HDL (≥1.5mg/dl; HR 1.34 [1.12-1.59]), and decreased with elevated HDL (≥35mg/dl; HR 0.80 [0.67-0.96]). Transition to diabetes in Veterans was related in age-stratified risk score analyses to HbA1c, VLDL, HDL and TG/HDL, BMI, hypertension and race, with 5-year risk differentials of 62% for the lowest (5-year risk, 13.5%) vs. the highest quartile (5-year risk, 21.9%) of the risk score. This investigation identified substantial differentials in risk of diabetes in Veterans, based on a readily-derived risk score suitable for risk stratification for type 2 diabetes prevention.

Background/UNASSIGNED:Growing evidence suggests that cancer and diabetes may share common risk factors such as age, race/ethnicity, obesity, insulin resistance, sedentary lifestyle, smoking, and alcohol consumption. However, little is known about how habitual sleep duration (a known cardiometabolic risk factor) may affect the relationship between cancer and diabetes. The aim of this study was to investigate whether sleep duration moderated the relationship between history of cancer and diabetes. Methods/UNASSIGNED:Data were extracted from the National Health Interview Survey dataset from 2004 to 2013 containing demographics, chronic diseases, and sleep duration (N=236,406). Data were analyzed to assess the moderating effect of short and long sleep durations on cancer and diabetes mellitus. Results/UNASSIGNED:<0.05). Conclusion/UNASSIGNED:Our findings indicate that for cancer survivors, short sleep was associated with higher self-reported diabetes and long sleep duration may act as a buffer against diabetes mellitus, as the likelihood of self-reported diabetes was lower among cancer survivors who reported long sleep duration. Impact/UNASSIGNED:Findings from the current study have clinical and public health implications. Clinically, comprehensive sleep assessments and sleep interventions to improve sleep are needed for cancer survivors who have comorbid diabetes. Our findings can also spur public health reform to make sleep an important component of standard cancer survivorship care, as it reduces other chronic disease like diabetes.

BACKGROUND:Well-being is a positively-framed, holistic assessment of health and quality of life that is associated with longevity and better health outcomes. We aimed to identify county attributes that are independently associated with a comprehensive, multi-dimensional assessment of individual well-being. METHODS:We performed a cross-sectional study examining associations between 77 pre-specified county attributes and a multi-dimensional assessment of individual US residents' well-being, captured by the Gallup-Sharecare Well-Being Index. Our cohort included 338,846 survey participants, randomly sampled from 3,118 US counties or county equivalents. FINDINGS:We identified twelve county-level factors that were independently associated with individual well-being scores. Together, these twelve factors explained 91% of the variance in individual well-being scores, and they represent four conceptually distinct categories: demographic (% black); social and economic (child poverty, education level [<high school, high school diploma/equivalent, college degree], household income, % divorced); clinical care (% eligible women obtaining mammography, preventable hospital stays per 100,000, number of federally qualified health centers); and physical environment (% commuting by bicycle and by public transit). CONCLUSIONS:Twelve factors across social and economic, clinical care, and physical environmental county-level factors explained the majority of variation in resident well-being.

Alcohol, marijuana, and ecstasy (3,4-methylenedioxymethamphetamine [MDMA], 'Molly') are among the most prevalent substances used by young adults; however, few studies have focused on the specific sexual effects associated with use. Examining subjective sexual effects (e.g. increased libido) associated with use can inform prevention efforts. Data were analysed from 679 nightclub and dance festival attendees in New York City (ages 18-25) to examine and compare self-reported sexual effects associated with use of alcohol, marijuana, and ecstasy. Results suggest that compared to marijuana, alcohol and ecstasy were more strongly associated with heightened perceived sexual effects (i.e. perceived sexual attractiveness of self and others, sexual desire, length of intercourse, and sexual outgoingness). Increased body and sex organ sensitivity and increased sexual intensity were most commonly associated with ecstasy use. Sexual dysfunction was most common while using alcohol or ecstasy, especially among males, and females were more likely to report sexual dysfunction after using marijuana. Post-sex regret was most common with alcohol use. Alcohol, marijuana, and ecstasy each have different sexual effects; therefore, each is associated with different risks and benefits for users. Findings can inform prevention and harm reduction as young adults are prone to use these substances.

Aim and objective Injunctive norms about smoking, the perceived approval or acceptability of smoking from friends or wider peer group, have rarely been studied outside the Western world. We investigated injunctive norms and the associations with smoking susceptibility in adolescents in Hong Kong, where most adolescents are negative towards smoking. Methods In 2017/18, 7031 Secondary 1-5 (US grade 7-11) students (48.9% boys; mean age 14.3, SD 1.7) were surveyed.Students reported the perceived approval of smoking from good friends (disapprove/neutral/approve) and the perception of whether most secondary school students accepted smoking (no/yes). Smoking susceptibility referred to the lack of a firm intention not to smoke in the next 12 months, when good friends smoked in front, or when a good friend offered a cigarette. Logistic regression yielded adjusted odds ratios (AORs) of smoking susceptibility for injunctive norms in never smokers, adjusting for sociodemographic characteristics and school clustering effect. Results Overall, 1.3%, 21.1% and 77.5% of students perceived approval, neutral response and disapproval of smoking from good friends, respectively. Some (5.8%) perceived that most students accepted smoking. In never smokers (n=6472, 92.5%), compared with perceived disapproval from good friends, perceived neutral response (AOR 3.58, 95% CI 2.86-4.50) and approval (5.41, 2.93-9.97) were associated with smoking susceptibility. The perception that most students accepted smoking was also associated with smoking susceptibility (2.73, 2.02-3.71). Conclusions Injunctive norms were associated with smoking susceptibility in Hong Kong never smoking adolescents. Addressing misperceptions of others' approval or acceptability of smoking may help prevent adolescent smoking.

Changes in select adipose tissue volumes may differentially impact bone mineral density. This study was performed to assess cross-sectional and longitudinal relationships between computed tomography-determined visceral (VAT), subcutaneous (SAT), inter-muscular (IMAT), and pericardial adipose tissue (PAT) volumes with respective changes in thoracic vertebral and lumbar vertebral volumetric trabecular bone mineral density (vBMD) in African Americans with type 2 diabetes. Generalized linear models were fitted to test relationships between baseline and change in adipose volumes with change in vBMD in 300 African American-Diabetes Heart Study participants; adjustment was performed for age, sex, diabetes duration, study interval, smoking, hypertension, BMI, kidney function, and medications. Participants were 50% female with mean ± SD age 55.1±9.0 years, diabetes duration 10.2±7.2 years, and BMI 34.7±7.7 kg/m2. Over 5.3 ± 1.4 years, mean vBMD decreased in thoracic/lumbar spine, while mean adipose tissue volumes increased in SAT, IMAT, and PAT, but not VAT depots. In fully-adjusted models, changes in lumbar and thoracic vBMD were positively associated with change in SAT (β[SE] 0.045[0.011], p<0.0001; 0.40[0.013], p = 0.002, respectively). Change in thoracic vBMD was positively associated with change in IMAT (p = 0.029) and VAT (p = 0.016); and change in lumbar vBMD positively associated with baseline IMAT (p<0.0001). In contrast, vBMD was not associated with change in PAT. After adjusting for BMI, baseline and change in volumes of select adipose depots were associated with increases in thoracic and lumbar trabecular vBMD in African Americans. Effects of adiposity on trabecular bone appear to be site-specific and related to factors beyond mechanical load.

Background: suPAR is an inflammatory mediator that has been linked to the pathogenesis of FSGS and progression of chronic kidney disease in children and adults. Overexpression of suPAR leads to reduced nephron development in preclinical models. This study was designed to measure suPAR in pregnant women to determine the range of fetal exposure to this molecule and its potential influence on antenatal human kidney growth.
Method(s): Pregnant women enrolled in the Children's Health and Environment Study (CHES) provided serum samples obtaining during 1-3 trimesters. Clinical information was obtained from the electronic health record. suPAR levels were determined by ELISA (Virogates, Copenhagen, Denmark). Data are presented as mean+/-SD. Results were analyzed by Pearson correlation and ANOVA.
Result(s): 515 mothers were studied, age 31+/-6 yr, and racial distribution 44% Caucasian, 7% African American, 9 % Asian, and 41% other/unspecified. 46% of the women were Hispanic. 29% had completed a high school education or less and 28% had an annual income <$50,000. There were 464 livebirths, 50.4% girls. The serum suPAR levels (mean, SD, minimum, maximum) are summarized in the Table. The suPAR levels in the subgroup of women who provided more than one sample during pregnancy were closely correlated (r=0.79-0.94, P<0.0001)). The decline in serum suPAR levels from trimester 1 to 3 was highly significant (P<0.001).
Conclusion(s): Maternal suPAR levels are detectable throughout pregnancy but decline from trimester 1 to 3. The levels are highly correlated and steady during the course of pregnancy in an individual woman. There is more than a 10-fold range in suPAR concentration which may contribute to the biological variation in nephron number at birth. Follow-up assessment in the infants will be performed in the prospective Environmental Influences on Child Health Outcomes (ECHO) cohort study. (Table Presented)

The recent Ebola outbreak in West Africa was an exemplar for the need to rapidly measure population-level health-seeking behaviors, in order to understand healthcare utilization during emergency situations. Taking advantage of the high prevalence of mobile phones, we deployed a national SMS-poll and collected data about individual-level health and health-seeking behavior throughout the outbreak from 6694 individuals from March to June 2015 in Liberia. Using propensity score matching to generate balanced subsamples, we compared outcomes in our survey to those from a recent household survey (the 2013 Liberian Demographic Health Survey). We found that the matched subgroups had similar patterns of delivery location in aggregate, and utilizing data on the date of birth, we were able to show that facility-based deliveries were significantly decreased during, compared to after the outbreak (p < 0.05) consistent with findings from retrospective studies using healthcare-based data. Directly assessing behaviors from individuals via SMS also enabled the measurement of public and private sector facility utilization separately, which has been a challenge in other studies in countries including Liberia which rely mainly on government sources of data. In doing so, our data suggest that public facility-based deliveries returned to baseline values after the outbreak. Thus, we demonstrate that with the appropriate methodological approach to account for different population denominators, data sourced via mobile tools such as SMS polling could serve as an important low-cost complement to existing data collection strategies especially in situations where higher-frequency data than can be feasibly obtained through surveys is useful.
