Failures of self-regulation are common, leading to many of the most vexing problems facing contemporary society, from overeating and obesity to impulsive sexual behavior and STDs. One reason that people may be prone to engaging in unwanted behaviors is heightened sensitivity to cues related to those behaviors; people may overeat because of hyperresponsiveness to food cues, addicts may relapse following exposure to their drug of choice, and some people might engage in impulsive sexual activity because they are easily aroused by erotic stimuli. An open question is the extent to which individual differences in neural cue reactivity relate to actual behavioral outcomes. Here we show that individual differences in human reward-related brain activity in the nucleus accumbens to food and sexual images predict subsequent weight gain and sexual activity 6 months later. These findings suggest that heightened reward responsivity in the brain to food and sexual cues is associated with indulgence in overeating and sexual activity, respectively, and provide evidence for a common neural mechanism associated with appetitive behaviors. © 2012 the authors.

It is imperative that young adult cancer survivors address any modifiable risk factors, given their increased health risks. Unfortunately, few behavioral interventions have been developed for this population. The literature on physical activity, smoking, and alcohol and drug use among young adult cancer survivors was reviewed in order to identify the behaviors most in need of intervention, the most vulnerable subsets of the population, and the health behavior theories that might guide intervention development. This literature indicates that young adult cancer survivors are not meeting physical activity recommendations though smoking and risky drinking appear less pervasive than in the general population. Several demographic and medical characteristics are associated with health behaviors, indicating subsets of the population particularly in need of intervention. The literature also indicates that a few different theories and models (e.g., social cognitive theory, self-determination theory) might be useful in guiding the development of interventions for this population. © 2010 Springer Science+Business Media, LLC.

Background. Prognostic factors and outcomes in patients with marginal zone lymphoma (MZL) have been studied in small cohort studies, which may not reflect the population at large. Methods. Clinical characteristics and survival outcomes of adult patients with MZL who were diagnosed between 1995 and 2009 were evaluated using the Surveillance, Epidemiology, and End Results (SEER) database. The authors generated clinical prognostic models for subtypes of MZL and compared survival during the periods of 1995 through 2000, 2001 through 2004, and 2005 through 2009. Results. The prognosis was significantly better for patients with mucosa-associated lymphoid tissue (MALT) lymphoma (5-year relative survival rate of 88.7%; P <.0001) compared with those with the splenic MZL (SMLZ)or nodal MZL (NMZL) subtypes (5-year relative survival rates of 79.7% and 76.5%, respectively). There was evidence of improved outcomes in patients with NMZL and MALT lymphomas between 1995 and 2009 (P <.0001), with no difference noted in patients with SMZL (P =.56). Advancing age and the presence of B symptoms had prognostic significance in all MZL subtypes. Male sex and stage of disease were significant only for the NMZL and MALT categories. Survival in patients with MALT lymphomas varied depending on the site of origin, with a worse prognosis noted in those with gastrointestinal and pulmonary locations of origin (5-year incidence rate of lymphoma-related death, 9.5%-14.3%) compared with ocular, cutaneous, and endocrine sites (4.5%-7.8%; P <.0001). Conclusions. The survival for patients with SMZL is similar to that for those with NMZL, and unlike the NMZL and MALT subtypes, it has not improved over the past decade. The prognosis of patients with MALT lymphoma varies according to the anatomical site of origin. Cancer 2013. © 2012 American Cancer Society. Source

Aims/hypothesis: Both obesity and genetics contribute to cardiovascular disease (CVD). We examined whether a genetic risk score (GRS) prospectively predicted cardiovascular morbidity and mortality among overweight/obese individuals with type 2 diabetes and whether behavioural weight loss could diminish this association. Methods: Look AHEAD (Action for Health in Diabetes) is a randomised controlled trial to determine the effects of intensive lifestyle intervention (ILI), including weight loss and physical activity, relative to diabetes support and education, on cardiovascular outcomes among overweight/obese individuals with type 2 diabetes. Of the participants, 4,016 provided consent for genetic analyses and had DNA samples passing quality control procedures. These secondary data analyses focused on whether a GRS derived from 153 single nucleotide polymorphisms (SNPs) associated with coronary artery disease in the most recent genome-wide association study predicted cardiovascular morbidity and mortality over a median of 9.6 years of follow-up, and whether ILI would diminish this association. Results: The GRS significantly predicted the primary composite endpoint of death from cardiovascular causes, nonfatal myocardial infarction, nonfatal stroke, or hospitalisation for angina in the full sample (HR, 95% CI per 1 SD increase in GRS: 1.19 [1.10, 1.28]) and among individuals with no known history of CVD at baseline (HR 1.18 [95% CI 1.07, 1.30]). In no case did ILI significantly alter this association. Conclusions/interpretation: A GRS comprised of SNPs significantly predicts cardiovascular morbidity and mortality over 9.6 years of follow-up in Look AHEAD. Lifestyle intervention did not alter the genetic association. Clinical Trial Registration: NCT00017953; NCT01270763 © 2015, Springer-Verlag Berlin Heidelberg. Source

An office evaluation of men's health in primary care requires a thorough understanding of the implications of male sexual dysfunctions, hypogonadism, and cardiometabolic risk stratification and aggressive risk management. The paradigm of the men's health office visit in primary care is the recognition and assessment of male sexual dysfunction, specifically erectile dysfunction, and its value as a signal of overall cardiometabolic health, including the emerging evidence linking low testosterone and the metabolic syndrome. Indeed, erectile dysfunction may now be thought of as a harbinger of cardiovascular clinical events and other systemic vascular diseases in some men. © 2012 Elsevier Inc. Source
