Predictors of psychological distress and interest in mental health services in individuals with cancer.
J Health Psychol
PUBLISHED: 09-11-2014
Show Abstract
Hide Abstract
Identifying risk factors for psychological distress in patients with cancer may help providers more efficiently screen, identify, and manage distress. This article presents predictors of psychological distress in a large heterogeneous sample of cancer patients. In total, 836 patients were enrolled in a large randomized control trial and completed computerized psychosocial assessments Mental Health Assessment and Dynamic Referral for Oncology. Multivariate regressions examined predictors of distress and interest in mental health services. Final models suggest that psychological distress was related to six variables, and interest in mental health services was related to previous history of mental health counseling, total number of cancer-related symptoms, and race/ethnicity. Results may be used to identify high-risk patients who may benefit from proactive psychosocial interventions.

Evaluating the Framingham hypertension risk prediction model in young adults: the Coronary Artery Risk Development in Young Adults (CARDIA) study.
Hypertension
PUBLISHED: 09-16-2013
Show Abstract
Hide Abstract
A prediction model was developed in the Framingham Heart Study (FHS) to evaluate the short-term risk of hypertension. Our goal was to determine the predictive ability of the FHS hypertension model in a cohort of young adults advancing into middle age and compare it with the predictive ability of prehypertension and individual components of the FHS model. We studied 4388 participants, aged 18 to 30 years without hypertension at baseline, enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) Study, who participated in 2 consecutive examinations occurring 5 years apart between the baseline (1985-1986) and year 25 examination (2010-2011). Weibull regression was used to assess the association of the FHS model overall, individual components of the FHS model, and prehypertension with incident hypertension. During the 25-year follow-up period, 1179 participants developed incident hypertension. The FHS hypertension model (c-index=0.84; 95% confidence interval, 0.83-0.85) performed well in discriminating those who did and did not develop hypertension and was better than prehypertension alone (c-index=0.71; 95% confidence interval, 0.70-0.73). The predicted risk from the FHS hypertension model was systematically lower than the observed hypertension incidence initially (?(2)=249.4; P<0.001) but demonstrated a good fit after recalibration (?(2)=14.6; P=0.067). In summary, the FHS model performed better than prehypertension and may be a useful tool for identifying young adults with a high risk for developing hypertension.

Randomized control trial to test a computerized psychosocial cancer assessment and referral program: methods and research design.
Contemp Clin Trials
PUBLISHED: 01-22-2013
Show Abstract
Hide Abstract
The National Cancer Coalition Network, National Cancer Institute, and American College of Surgeons all emphasize the need for oncology providers to identify, address, and monitor psychosocial needs of their patients. The Mental Health Assessment and Dynamic Referral for Oncology (MHADRO) is a patient-driven, computerized, psychosocial assessment that identifies, addresses, and monitors physical, psychological, and social issues faced by oncology patients. This paper presents the methodology of a randomized controlled trial (RCT) that tested the impact of the MHADRO on patient outcomes at 2, 6, and 12 months. Patient outcomes including overall psychological distress, depression, anxiety, functional disability, and use of psychosocial resources will be presented in future publications after all follow-up data is gathered. Eight hundred and thirty six cancer patients with heterogeneous diagnoses, across three comprehensive cancer centers in different parts of the United States, were randomized to the MHADRO (intervention) or an assessment-only control group. Patients in the intervention group were provided detailed, personalized reports and, when needed, referrals to mental health services; their oncology provider received detailed reports designed to foster clinical decision making. Those patients who demonstrated high levels of psychosocial problems were given the option to authorize that a copy of their report be sent electronically to a "best match" mental health professional. Demographic and patient cancer-related data as well as comparisons between patients who were enrolled and those who declined enrollment are presented. Challenges encountered during the RCT and strategies used to address them are discussed.

Hide Abstract
Women are more likely than men to forgo, delay, and ration medical care because of medical debt. Using 2003-04 Community Tracking Study Household Survey data, this study examined gender differences in five financial hardships associated with medical debt. Regression analyses accounting for predisposing, enabling, and need factors of health services use indicated women were less likely to report being contacted by a collection agency (b=-0.15, p<.05), using savings (b=-0.23, p<.005), or having any financial hardships associated with medical debt (b=-0.24, p<.05). There were no significant gender differences in putting off major purchases, borrowing money, and problems paying for necessities. Similarly, there were positive and negative relationships between medical debt financial hardships and income, insurance, and health status. Findings suggest that making health care affordable and equitable is critically important for both men and women. Research is needed to understand the differential impact of medical debt, especially among disadvantaged populations.

Hide Abstract
Nondippers (people whose sleep systolic blood pressure [SBP] fails to decrease >10% from daytime SBP) have increased risk of cardiovascular disease. The prevalence of nondipping in younger adults has not been well studied, nor has its value for predicting hypertension. We examined the prevalence of nondipping in a substudy of the Coronary Artery Risk Development in Young Adults (CARDIA) Study. We used Cox regression to estimate the hazard ratio (HR) conferred by nondipping for incident prehypertension or hypertension (preHTN/HTN) over 15 years. Of the 264 nonhypertensive participants at baseline, 118 (45%) were nondippers. Blacks were more likely than whites to be nondippers (52% versus 33%, P = .004). The incidence rate of preHTN/HTN was 29.2/1000 person-years among dippers and 36.2/1000 person-years among nondippers. Compared with those in the lowest quartile of nighttime to daytime SBP, those in the highest quartile were more likely to develop preHTN/HTN (HR 1.61; P = .06), but this relationship was attenuated after adjustment (HR 1.34; P = .27). Our results demonstrate that nondipping is common in young, nonhypertensive adults, and is more common in blacks than whites. Nondipping might predate a meaningful clinically detected increase in BP in some people, but more research in larger study samples is needed.

Hide Abstract
Aflatoxins are fungal metabolites that contaminate staple food crops in many developing countries. Up to 40% of women attending a prenatal clinic in Africa may be anemic. In a cross-sectional study of 755 pregnant women, Aflatoxin B(1)-lysine adducts (AF-ALB) levels were determined by high-performance liquid chromatography. Participants were divided into quartiles "low," "moderate," "high," and "very high." Anemia was defined as hemoglobin levels < 11 g/dL. Logistic regression was used to examine the association of anemia with AF-ALB. The mean AF-ALB level was 10.9 pg/mg (range = 0.44-268.73 pg/mg); 30.3% of participants were anemic. The odds of being anemic increased 21% (odds ratio [OR], 1.21, P = 0.01) with each quartile of AF-ALB reaching an 85% increased odds in the "very high" compared with the "low" category (OR, 1.85; confidence interval [CI], 1.16-2.95). This association was stronger among women with malaria and findings were robust when women with evidence of iron deficiency anemia were excluded. This study found a strong, consistent association between anemia in pregnancy and aflatoxins.

Alcohol consumption in young adults and incident hypertension: 20-year follow-up from the Coronary Artery Risk Development in Young Adults Study.

Hide Abstract
The relation between alcohol consumption and incident hypertension is unclear, and most observational studies have not accounted for socioeconomic factors. This study examined the association between alcohol consumption in a diverse group of young adults and incident hypertension over 20 years. Participants (n = 4,711) were from the Coronary Artery Risk Development in Young Adults Study cohort, recruited in 1985 (aged 18-30 years) from Birmingham, Alabama; Chicago, Illinois; Minneapolis, Minnesota; and Oakland, California. The 20-year incidence of hypertension for never, former, light, moderate, and at-risk drinkers was 25.1%, 31.8%, 20.9%, 22.2%, and 18.8%, respectively (P < 0.001). Race, gender, age, family history of hypertension, body mass index, income, education, and difficulty paying for basics and medical care were associated with hypertension. Adjustment using Cox proportional hazard models revealed no association between baseline alcohol consumption and incident hypertension, except among European-American women in whom any current alcohol consumption was associated with lower risk of incident hypertension. The lack of association between alcohol and hypertension in the majority of this socioeconomically diverse cohort is not definitive. Future studies should include social factors, such as income and education, and consider additional characteristics that may modify or confound associations between alcohol and blood pressure.

Sleep duration has been inversely associated with body mass index (BMI). We examined the relationship between self-reported sleep duration and BMI, waist circumference, and percent body fat in Black and White individuals from the CARDIA study. Box-Tidwell regression models were adjusted for age and race (Model 1), additional lifestyle and demographic variables (Model 2), and physical activity (Model 3). There were significant interactions between sleep and gender for the main outcome variables. In men, there was a trend for an inverse relationship between reported sleep duration and BMI in Model 2 (beta = -0.20, P = .053) but not model 3 (beta = -0.139, P = .191). In women, inverse relationships were observed between sleep duration and BMI (beta = -0.294, P = .005) and waist circumference (beta = -0.442, P = .059), in Model 2. These associations became nonsignificant in model 3 (BMI: beta = -0.172, P = .084; waist circumference: beta = -0.161, P = .474). Our results are consistent with previous findings that sleep is associated with BMI and other body composition variables. However, the relationship between self-reported sleep duration and body composition may be stronger in women than in men.

This study aimed to estimate the prevalence of tobacco use and to describe the demographic profile of female smokers in Paraná State, Brazil. The study used a cross-sectional population-based design with cluster sampling (n = 2,153) of women 18 years or older in seven cities. Prevalence of smoking was 13.4%, ranging from 10% in Cascavel to 19% in Irati. According to multivariate analysis, city of residence, marital status, and schooling were significantly associated with tobacco use. Women in Irati (OR = 2.08; 95%CI: 1.22-3.54) were more likely to smoke than those in Cambé. Married women and widows were less likely to smoke (OR = 0.47; 95%CI: 0.30-0.73 and OR = 0.43; 95%CI: 0.22-0.87) than single women. Women living with a partner (but not married) were more likely to smoke than single women (OR = 2.49; 95%CI: 1.12-5.53), and women with university degrees were less likely to smoke than those with eight years of school or less (OR = 0.41; 95%CI: 0.22-0.87). The results confirm the need for tobacco control programs that take gender and regional differences into account.

Nighttime blood pressure dipping in young adults and coronary artery calcium 10-15 years later: the coronary artery risk development in young adults study.
Hypertension
Show Abstract
Hide Abstract
Nighttime blood pressure (BP) dipping can be quantified as the ratio of mean nighttime (sleep) BP to mean daytime (awake) BP. People whose dipping ratio is ? 0.90 have been referred to as nondippers, and nondipping is associated with cardiovascular disease events. We examined the relationship between systolic nighttime BP dipping in young adults and the presence of coronary artery calcium (CAC) 10 to 15 years later using data from the ambulatory BP monitoring substudy of the Coronary Artery Risk Development in Young Adults Study. Among 239 participants with adequate measures of both nighttime and daytime readings and coronary artery calcium, the systolic BP dipping ratio ranged from 0.72 to 1.24 (mean, 0.88; SD, 0.06), and CAC was present 10 to 15 years later in 54 participants (22.6%). Compared with those whose systolic BP dipping ratio ranged from 0.88 to 0.92 (quartile 3), the 57 participants (23.9%) with less pronounced or absent dipping (ratio, 0.92-1.24; quartile 4) had an unadjusted odds ratio of 4.08 (95% CI, 1.48-11.2) for the presence of CAC. The 60 participants (25.1%) with a more pronounced dipping (ratio, 0.72-0.85; quartile 1) also had greater odds for presence of CAC (odds ratio, 4.76 [95% CI, 1.76-12.9]). When modeled as a continuous predictor, a U-shaped relationship between systolic BP dipping ratio and future CAC was apparent and persisted after adjustment for multiple potential confounders (P<0.001 for quadratic term). Both failure of systolic BP to dip sufficiently and "overdipping" during nighttime may be associated with future subclinical coronary atherosclerosis.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
