OBJECTIVE: Mindfulness meditation training has been previously shown to enhance behavioral measures of executive control (e.g. attention, working memory, cognitive control), but the neural mechanisms underlying these improvements are largely unknown. Here, we test whether mindfulness training interventions foster executive control by strengthening functional connections between dorsolateral prefrontal cortex (dlPFC) - a hub of the executive control network - and frontoparietal regions that coordinate executive function...

OBJECTIVES: The aim of the European Network for the Investigation of Gender Incongruence is to investigate the status of all individuals who had applied for gender confirming interventions from 2007 until 2009, irrespective of whether they received treatment. The current article describes the study protocol, the effect of medical treatment on gender dysphoria and body image, and the predictive value of (pre)treatment factors on post-treatment outcomes. METHODS: Data were collected on medical interventions, transition status, gender dysphoria (Utrecht Gender Dysphoria Scale), and body image (Body Image Scale for Transsexuals)...

OBJECTIVE: Ovarian cancer (OvCA) is a leading cause of cancer death for women. Depression and social isolation have been associated with a higher OvCA risk and poorer survival, but other forms of chronic psychosocial stress, including work-related characteristics, remain understudied. METHODS: Women from three prospective cohorts (Nurses' Health Study (NHS), n=31,754; Nurses' Health Study II (NHSII), n=74,260; Northern Sweden Health and Disease Study (NSHDS); nnested case-control study=196) completed a job questionnaire, assessing demand and control at work, social support provided by coworkers and supervisor, and job security...

OBJECTIVE: Several cross-sectional studies reported a relationship between post-traumatic stress disorder (PTSD) and epilepsy. However, the temporal association between PTSD and epilepsy has rarely been investigated. We hypothesized that the risk of developing epilepsy later in life would be higher in patients with PTSD than in those without PTSD. METHODS: Using the Taiwan National Health Insurance Research Database, 6425 individuals with PTSD and 24,980 age-/sex-matched controls were enrolled between 2002 and 2009 in our study, and followed up to the end of 2011...

OBJECTIVE: Reduced mental health is prevalent in rheumatoid arthritis (RA). Although longitudinal studies are limited, there is evidence that depression associates with worse disease outcomes. We evaluated reciprocal relationships between mental health, RA severity and genetic risks for depression over 2-years in a well-characterised cohort of RA patients. METHODS: We evaluated 520 early RA patients previously enrolled to two clinical trials. Mental health was measured using the SF-36 mental health (MH) domain and mental component summary scores (MCS)...

OBJECTIVE: The purpose of this study was to examine whether enterotypes in the gut microbiome could be determined by clustering validity indexes and whether these enterotypes were associated with individual differences in temperament traits. METHODS: Sixty healthy Korean participants (21 men; 27.5 ± 8.1 years, 39 women; 34.5 ± 14.3 years) were asked to answer 60 temperament questions (novelty seeking, harm avoidance, reward dependence, and persistence) from the Korean version of the temperament and character inventory-125 (K-TCI-125)...

OBJECTIVE: Studies suggest that torture survivors often suffer long-term chronic pain and increased pain perception. However, it is unclear whether the actual experience of torture, or rather the subsequent posttraumatic stress disorder (PTSD), explains these pain problems. Furthermore, while catastrophic and fearful orientations to pain have been suggested to play a significant role in the association between trauma and pain, the underlying mechanisms remain unclear. This study examined whether chronic pain and pain perception among torture survivors are associated with torture experience or PTSD and whether catastrophic and fearful orientations mediate or moderate these associations...

OBJECTIVE: To examine the current evidence for executive function (EF) performance differences between groups with Type 1 diabetes mellitus (T1DM) and non-diabetic control groups during adolescence and early adulthood, and to explore the relationships between EF and diabetes-related risk factors. METHODS: A systematic review of the literature examining EF performance in groups with T1DM was conducted according to the PRISMA guidelines. Electronic database searches for published and unpublished literature yielded a final set of 26 articles after application of inclusion and exclusion criteria...

OBJECTIVE: Poor behavioral self-regulation in the first two decades of life has been identified as an important precursor of disease risk in adulthood. However, physiological regulation has not been well-studied as a disease risk factor before adulthood. We tested whether physiological regulation at age two, in the form of vagal regulation of cardiac function (indexed by RSA change), would predict three indicators of cardiovascular risk at age 16 (diastolic and systolic blood pressure and body mass index)...

This issue of Psychosomatic Medicine describes findings from an innovative study by Kang et al. employing neuroimaging methods to quantify neural responses to health communications. Findings indicated that those sedentary individuals who hold self-transcendent values show attenuated limbic threat responses to communications about the benefits of physical activity. Furthermore, participants who were instructed to articulate such values showed some evidence of additional blunting of the same neural response. In this editorial we provide context for the interpretation of these findings within the existing research using the brain-as-predictor approach, and other recent trends within biobehavioral medicine involving the use of neuroscience methods in the service of health behavior change...

OBJECTIVE: Our aim was to evaluate the bacterial profiles of young monkeys as they were weaned into peer groups with a particular focus on Prevotella, an important taxon in both human and nonhuman primates. The weaning of infants and increased social contact with peers is a developmental stage that is likely to affect the gut microbiome. METHODS: Gut bacteria were assessed in 63 rhesus monkeys living in social groups comprised of 4-7 individuals. Two groups were assessed prospectively on Day 1 and 2 weeks after rehousing away from the mother and group formation...

OBJECTIVE: A quarter of the world's population suffers from metabolic syndrome (MetS). MetS prevalence stratifies by socioeconomic status (SES), such that low SES is associated with higher MetS risk. The present study compared the associations between early-life SES and current SES with MetS. METHODS: Participants (N = 354, ages 15-55, M = 36.5 years, SD = 10.7; 55% female; 72.9% White, 16.9% Asian, 10.2% other) were evaluated for SES and MetS. All were in good health, defined as free of chronic medical illness and acute infectious disease...

OBJECTIVE: We used quantitative genetic methods to evaluate whether sleep quality, pain, and depression symptoms share a common genetic diathesis, to estimate the genetic and environmental sources of covariance among these symptoms, and to test for possible causal relationships. METHODS: A community sample of 400 twins from the University of Washington Twin Registry completed standardized self-report questionnaires. We used biometric modeling to assess genetic and environmental contribution to the association between sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI), pain measured by the Brief Pain Inventory (BPI), and depression symptoms measured by the Brief Symptom Inventory (BSI-dep)...

OBJECTIVE: In clinical trials, omega-3 fatty acid supplementation improves symptoms in psychiatric disorders involving dysregulated mood and impulse control, yet it is unclear whether in healthy adults omega-3 fatty acid supplementation affects mood, impulse control and the brain systems supporting these processes. Accordingly, this study tested the hypotheses that eciosapentaenoic (EPA) and docosahexaenoic (DHA) acid supplementation reduces negative affect and impulsive behaviors in healthy adults and that these changes correspond to alterations in corticolimbic and corticostriatal brain systems which support affective and impulsive processes...

Fatigue is a common prodromal symptom for various medical conditions, including acute myocardial infarction. Fatigue is also the core component of vital exhaustion, which consists of a specific triad: excessive fatigue, increased irritability, and feelings of demoralization. In this issue of Psychosomatic Medicine, Frestad and Prescott present a meta-analysis of 16 studies, involving 53,337 participants, which found vital exhaustion to be associated with an increased risk of incident coronary heart disease (CHD) and recurrent cardiac events among individuals with established CHD...

OBJECTIVES: Evidence suggests that sleep quality is worse in nonwhite minorities compared with whites. Poor sleep is associated with higher levels of perceived interpersonal discrimination, which is consistently reported among minorities. However, the literature is limited in exploring discrimination with both objective and subjective sleep outcomes in the same sample. We examined the relationship between discrimination and markers of subjective and objective sleep in a racially diverse sample...

OBJECTIVE: Psychomotor slowing is a common cognitive complication in type 1 diabetes (T1D), but its neuroanatomical correlates and risk factors are unclear. In non-diabetic adults, smaller gray matter volume (GMV) and presence of white matter hyperintensities (WMH) are associated with psychomotor slowing. We hypothesize that smaller GMV in prefronto-parietal regions explains T1D-related psychomotor slowing. We also inspect the contribution of microvascular disease and hyperglycemia. METHODS: GMV, WMH, and glucose levels were measured concurrently with a test of psychomotor speed (Digit Symbol Substitution Test, DSST) in 95 adults with childhood-onset T1D (mean age/duration=49/41 years) and 135 similarly-aged non-T1D adults...

OBJECTIVE: Accumulating evidence shows that psychosocial work factors of the demand-control and effort-reward imbalance models may contribute to increase blood pressure (BP). Women are more likely to be exposed to these psychosocial factors than men. Moreover, women spend twice as much time per week performing family responsibilities than men. This study aims to evaluate the longitudinal association of the double exposure to psychosocial work factors and high family responsibilities in women with BP over a 5-year follow-up...

BACKGROUND: Alterations in brain-gut communication and the intestinal microenvironment have been implicated in a variety of medical and neuropsychiatric diseases. Three central areas require basic and clinical research: (1) how the intestinal microenvironment interacts with the host immune system, central nervous system and enteric nervous system; (2) the role of the intestinal microenvironment in the pathogenesis of medical and neuropsychiatric disease; (3) the effects of diet, prebiotics, probiotics and fecal microbiota transplantation on the intestinal microenvironment and the treatment of disease...

OBJECTIVE: Prospective studies testing the potential impact of diabetes complications on depression are limited. The present study examined the longitudinal associations between diabetes complications and the risk and recurrence/persistence of depressive symptoms. METHODS: Data were from a prospective community cohort telephone survey of adults with diabetes (N= 1,314). Diabetes complications and depressive symptoms were assessed via self-report (Diabetes Complications Index and Patient Health Questionnaire-9, respectively) at baseline and annually for 5 years...
