The Heritability of Type D Personality by an Extended Twin-Pedigree Analysis in the Netherlands Twin Register.

Type D (Distressed) personality combines negative affectivity (NA) and social inhibition (SI) and is associated with an increased risk of cardiovascular disease. We aimed to (1) validate a new proxy based on the Achenbach System of Empirically Based Assessment (ASEBA) for Type D personality and its NA and SI subcomponents and (2) estimate the heritability of the Type D proxy in an extended twin-pedigree design in the Netherlands Twin Register (NTR). Proxies for the dichotomous Type D classification, and continuous NA, SI, and NAxSI (the continuous measure of Type D) scales were created based on 12 ASEBA items for 30,433 NTR participants (16,449 twins and 13,984 relatives from 11,106 pedigrees) and sources of variation were analyzed in the 'Mendel' software package. We estimated additive and non-additive genetic variance components, shared household and unique environmental variance components and ran bivariate models to estimate the genetic and non-genetic covariance between NA and SI. The Type D proxy showed good reliability and construct validity. The best fitting genetic model included additive and non-additive genetic effects with broad-sense heritabilities for NA, SI and NAxSI estimated at 49%, 50% and 49%, respectively. Household effects showed small contributions (4-9%) to the total phenotypic variation. The genetic correlation between NA and SI was .66 (reflecting both additive and non-additive genetic components). Thus, Type D personality and its NA and SI subcomponents are heritable, with a shared genetic basis for the two subcomponents.

Personalized eHealth Program for Life-style Change: Results From the "Do Cardiac Health Advanced New Generated Ecosystem (Do CHANGE 2)" Randomized Controlled Trial.

OBJECTIVE: Unhealthy life-style factors have adverse outcomes in cardiac patients. However, only a minority of patients succeed to change unhealthy habits. Personalization of interventions may result in critical improvements. The current randomized controlled trial provides a proof of concept of the personalized Do Cardiac Health Advanced New Generation Ecosystem (Do CHANGE) 2 intervention and evaluates effects on a) life-style and b) quality of life over time. METHODS: Cardiac patients (n = 150; mean age = 61.97 ± 11.61 years; 28.7% women; heart failure, n = 33; coronary artery disease, n = 50; hypertension, n = 67) recruited from Spain and the Netherlands were randomized to either the "Do CHANGE 2" or "care as usual" group. The Do CHANGE 2 group received ambulatory health-behavior assessment technologies for 6 months combined with a 3-month behavioral intervention program. Linear mixed-model analysis was used to evaluate the intervention effects, and latent class analysis was used for secondary subgroup analysis. RESULTS: Linear mixed-model analysis showed significant intervention effects for life-style behavior (Finteraction(2,138.5) = 5.97, p = .003), with improvement of life-style behavior in the intervention group. For quality of life, no significant main effect (F(1,138.18) = .58, p = .447) or interaction effect (F(2,133.1) = 0.41, p = .67) was found. Secondary latent class analysis revealed different subgroups of patients per outcome measure. The intervention was experienced as useful and feasible. CONCLUSIONS: The personalized eHealth intervention resulted in significant improvements in life-style. Cardiac patients and health care providers were also willing to engage in this personalized digital behavioral intervention program. Incorporating eHealth life-style programs as part of secondary prevention would be particularly useful when taking into account which patients are most likely to benefit.

A Personalized eHealth Intervention for Lifestyle Changes in Patients With Cardiovascular Disease: Randomized Controlled Trial.

BACKGROUND: Behavior change methods involving new ambulatory technologies may improve lifestyle and cardiovascular disease outcomes. OBJECTIVE: This study aimed to provide proof-of-concept analyses of an intervention aiming to increase (1) behavioral flexibility, (2) lifestyle change, and (3) quality of life. The feasibility and patient acceptance of the intervention were also evaluated. METHODS: Patients with cardiovascular disease (N=149; mean age 63.57, SD 8.30 years; 50/149, 33.5% women) were recruited in the Do Cardiac Health Advanced New Generation Ecosystem (Do CHANGE) trial and randomized to the Do CHANGE intervention or care as usual (CAU). The intervention involved a 3-month behavioral program in combination with ecological momentary assessment and intervention technologies. RESULTS: The intervention was perceived to be feasible and useful. A significant increase in lifestyle scores over time was found for both groups (F2,146.6=9.99; P<.001), which was similar for CAU and the intervention group (F1,149.9=0.09; P=.77). Quality of life improved more in the intervention group (mean 1.11, SD 0.11) than CAU (mean -1.47, SD 0.11) immediately following the intervention (3 months), but this benefit was not sustained at the 6-month follow-up (interaction: P=.02). No significant treatment effects were observed for behavioral flexibility (F1,149.0=0.48; P=.07). CONCLUSIONS: The Do CHANGE 1 intervention was perceived as useful and easy to use. However, no long-term treatment effects were found on the outcome measures. More research is warranted to examine which components of behavioral interventions are effective in producing long-term behavior change.

Maternal cognitive function during pregnancy in relation to hypo- and hyperthyroxinemia.

OBJECTIVE: To assess a possible relationship between maternal cognitive dysfunction during pregnancy and hypothyroxinemia, adjusted for major confounders. BACKGROUND: Thyroid dysfunction in general is associated with cognitive dysfunction. Cognitive dysfunction is common during pregnancy. DESIGN: Prospective follow-up study from 12 to 32 weeks of pregnancy. PARTICIPANTS: 2082 healthy pregnant women. MEASUREMENTS: Cognitive function, depression and sleeping problems were assessed by self-report questionnaires at 12, 22 and 32 weeks of gestation, higher scores reflecting more symptoms. FT4, TSH and TPO-Ab were assessed at 12 weeks of gestation. DEFINITIONS: healthy (euthyroxinemia) control group: FT4 within 10-90th percentiles, without elevated TPO-Ab titres and TSH within first trimester-specific reference range (0.23-4.0 mU/L). Hypothyroxinemia: FT4 <2.5th percentile with TSH within first trimester-specific reference range. Poor cognitive function: a score >1 SD > mean on the cognitive function scale. RESULTS: A total of 54 women showed hypothyroxinemia and 1476 women had euthyroxinemia. At 12 weeks, multiple logistic regression showed that poor cognitive function was independently related to hypothyroxinemia: OR: 2.9 (95% CI: 1.6-5.4), adjusted for depression (OR: 3.1; 95% CI: 2.7-4.6) and sleeping problems (OR: 2.8, 95% CI: 1.9-3.9). TPO-Ab + women with hypothyroxinemia had the highest levels of cognitive dysfunction. Other cut-offs of hypothyroxinemia (<5th or <10th percentile with normal TSH) showed similar results. GLM-ANOVA showed that throughout pregnancy women with hypothyroxinemia at 12 weeks had significantly higher cognitive dysfunction scores compared with the healthy controls: F = 12.1, P = .001. CONCLUSIONS: Women with hypothyroxinemia during early gestation are at risk for poor cognitive function throughout gestation, adjusted for depression and sleeping problems.

Effect of remote monitoring on patient-reported outcomes in European heart failure patients with an implantable cardioverter-defibrillator: primary results of the REMOTE-CIED randomized trial.

AIMS: The European REMOTE-CIED study is the first randomized trial primarily designed to evaluate the effect of remote patient monitoring (RPM) on patient-reported outcomes in the first 2 years after implantation of an implantable cardioverter-defibrillator (ICD). METHODS AND RESULTS: The sample consisted of 595 European heart failure patients implanted with an ICD compatible with the Boston Scientific LATITUDE® RPM system. Patients were randomized to RPM plus a yearly in-clinic ICD check-up vs. 3-6-month in-clinic check-ups alone. At five points during the 2-year follow-up, patients completed questionnaires including the Kansas City Cardiomyopathy Questionnaire and Florida Patient Acceptance Survey (FPAS) to assess their heart failure-specific health status and ICD acceptance, respectively. Information on clinical status was obtained from patients' medical records. Linear regression models were used to compare scores between groups over time. Intention-to-treat and per-protocol analyses showed no significant group differences in patients' health status and ICD acceptance (subscale) scores (all Ps > 0.05). Exploratory subgroup analyses indicated a temporary improvement in device acceptance (FPAS total score) at 6-month follow-up for secondary prophylactic in-clinic patients only (P < 0.001). No other significant subgroup differences were observed. CONCLUSION: Large clinical trials have indicated that RPM can safely and effectively replace most in-clinic check-ups of ICD patients. The REMOTE-CIED trial results show that patient-reported health status and ICD acceptance do not differ between patients on RPM and patients receiving in-clinic check-ups alone in the first 2 years after ICD implantation.ClinicalTrials.gov Identifier: NCT01691586.

Type D personality in Russian patients with cardiovascular disease: validity of the Russian DS14 (DS14-RU).

BACKGROUND: Type D personality is associated with unfavorable outcomes in patients with cardiovascular diseases (CVD). However, there is no valid Type D Scale in Russian language. The purpose of the study was to examine the factor structure of a new Russian version of 14-item Type D Scale (DS14-RU), and to evaluate the reliability and construct validity of the DS14-RU in clinical research. METHODS: The study included 929 participants, 496 (53.4%) of which had coronary artery disease, 195 (21.0%) congestive heart failure, 84 (9.0%) arterial hypertension and 154 (16.6%) were relatively healthy volunteers. The mean age was 57.5 years, 565 (60.8%) participants were males. The respondents filled out an extended Russian version of the Type D scale and new DS14-RU, as well as the Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support, Reeder Stress Inventory, and State-Trait Personality Inventory. RESULTS: The new Russian version of DS14-RU was internally consistent with Cronbach's α = .80 for both the negative affectivity and social inhibition subscales. The prevalence of Type D personality, as measured with the DS14-RU, was 21.4% among patients with CVD, and 20.0% among relatively healthy participants. The mean scores for anxiety, depression, psychosocial stress and anger were significantly higher in patients with Type D personality and they had significantly lower levels of social support and curiosity. CONCLUSIONS: The new DS14-RU is consistent with the original DS14 in terms of reliability, factor structure and construct validity. The DS14-RU can be used for the reliable assessment of Type D in Russian-speaking respondents.

Remote monitoring of implantable cardioverter defibrillators: Patient experiences and preferences for follow-up.

BACKGROUND: Patient satisfaction with remote patient monitoring (RPM) of implantable cardioverter defibrillators (ICDs) seems to be high, yet knowledge on long-term patient experiences is limited. The European REMOTE-CIED study explored patients' experiences with RPM, examined patient's preferences for ICD follow-up, and identified determinants of patient's preferences in the first 2 years postimplantation. METHODS: European heart failure patients (N = 300; median age = 66 years [interquartile range (IQR) = 59-73], and 22% female) with a first-time ICD received a Boston Scientific LATITUDE RPM system (Marlborough, MA, USA) and had scheduled in-clinic follow-ups once a year. Patients completed questionnaires at 1-2 weeks and also at 3, 6, 12, and 24 months postimplantation and clinical data were obtained from their medical records. Patient evaluation data were analyzed descriptively, and Student's t-tests/Man-Whitney U tests or Chi-square tests/Fisher's exact tests were performed to examine determinants of patient preferences. RESULTS: At 2 years postimplantation, the median patient satisfaction score with the RPM system was 9 out of 10 (IQR = 8-10), despite 53% of the patients experiencing issues (eg, failure to transmit data). Of the 221 patients who reported their follow-up preferences, 43% preferred RPM and 19% preferred in-clinic follow-up. Patients with a preference for RPM were more likely to be higher educated (P = 0.04), employed (P = 0.04), and equipped with a new LATITUDE model (P = 0.04), but less likely to suffer from chronic obstructive pulmonary disease (P = 0.009). CONCLUSION: In general, patients were highly satisfied with RPM, but a subgroup preferred in-clinic follow-up. Therefore, physicians should include patients' concerns and preferences in the decision-making process, to tailor device follow-up to individual patients' needs and preferences.

Self-Care and Pathophysiological Function in Patients with Chronic Heart Failure.

BACKGROUND: Self-care is assumed to benefit physiological function associated with prognosis in patients with chronic HF, but studies examining these relations are lacking. This study aims to prospectively examine the association of self-reported HF self-care with HF-associated pathophysiological markers, including renal, hematological, and immune function. METHOD: Patients with chronic HF (n = 460, 66.2 ± 9.6 years, 75% men) completed questionnaires and provided blood samples at baseline and 12-month follow-up. Linear mixed models examined random intercept and fixed between- and within-subjects effects of global self-care and the individual self-care behaviors on log-transformed TNF-α, IL-6, and IL-10, the glomerular filtration rate of creatinine (GFRcreat), and hemoglobin (Hb), controlling for sociodemographic and clinical covariates. RESULTS: Self-care was independently associated with lower GFRcreat levels (ß = - .14, P = .023) and improvement in self-care with a reduction in GFRcreat (ß = - .03, P = .042). Individual self-care behaviors were differentially associated with renal, inflammatory, and hematological markers. Regular exercise was associated with level differences in IL-6 (P < .001), and improvement in exercise was associated with increasing GFRcreat (P = .002) and increasing Hb (P = .010). Fluid restriction was associated with lower overall GFRcreat (P = .006), and improvement in fluid restriction was associated with decreasing GFRcreat (P = .014). Low-sodium intake was associated with lower levels of Hb (P = .027), lower TNF-alpha (P = .011), and lower IL-10 (P = .029). Higher levels of medication adherence were associated with reduced pro-inflammatory activation (P < .007). CONCLUSION: Our findings suggest that better global self-care was associated with poorer renal function. Performing self-care behaviors such as regular exercise and medication adherence was associated with improved physiological functioning, while restriction of fluid and sodium, and the associated daily weight monitoring were associated with adverse levels of pathophysiological biomarkers.

Modeling Interactions Between Latent Variables in Research on Type D Personality: A Monte Carlo Simulation and Clinical Study of Depression and Anxiety.

Several approaches exist to model interactions between latent variables. However, it is unclear how these perform when item scores are skewed and ordinal. Research on Type D personality serves as a good case study for that matter. In Study 1, we fitted a multivariate interaction model to predict depression and anxiety with Type D personality, operationalized as an interaction between its two subcomponents negative affectivity (NA) and social inhibition (SI). We constructed this interaction according to four approaches: (1) sum score product; (2) single product indicator; (3) matched product indicators; and (4) latent moderated structural equations (LMS). In Study 2, we compared these interaction models in a simulation study by assessing for each method the bias and precision of the estimated interaction effect under varying conditions. In Study 1, all methods showed a significant Type D effect on both depression and anxiety, although this effect diminished after including the NA and SI quadratic effects. Study 2 showed that the LMS approach performed best with respect to minimizing bias and maximizing power, even when item scores were ordinal and skewed. However, when latent traits were skewed LMS resulted in more false-positive conclusions, while the Matched PI approach adequately controlled the false-positive rate.

Type D Personality as a Risk Factor in Coronary Heart Disease: a Review of Current Evidence.

PURPOSE OF THE REVIEW: This review article synthesizes recent research findings on the psychological context of Type D personality and the mechanisms through which Type D affects disease progression and prognosis among patients with coronary heart disease (CHD). RECENT FINDINGS: One in four patients with CHD has a Distressed (Type D) personality, which is characterized by two stable traits: social inhibition and negative affectivity. Type D personality predicts increased mortality and morbidity burden, and poorer health-related quality of life. Type D is part of a family of psychosocial risk factors that affect CHD prognosis. The pattern of co-occurrence of these psychosocial factors and intra-individual differences in psychosocial profiles may affect risk prediction accuracy. Multiple biological and behavioral processes have been associated with Type D personality. Identifying pathways explaining the observed associations between Type D personality and CHD is important to improve etiological and pathophysiological knowledge and to design personalized interventions, and targeting specific risk-associated pathways.

Pharmaceutically treated anxiety but not depression prior to cancer diagnosis predicts the onset of cardiovascular disease among breast cancer survivors.

PURPOSE: To examine the associations between pharmaceutically treated anxiety and depression present in the year prior to breast cancer diagnosis and the risk of incident cardiovascular disease (CVD), while controlling for traditional cardiovascular risk factors and clinical characteristics in a population-based observational study. METHODS: Adult 1-year breast cancer survivors (n = 7227), diagnosed between 01-01-1999 and 12-31-2010, with no history of CVD, were selected from the Netherlands Cancer Registry. Drug dispensing data were derived from the PHARMO Database Network and used as proxy for CVD, anxiety, and depression. By multivariable Cox regression analysis, we examined the risk associated with pharmaceutically treated anxiety and depression for developing CVD after cancer diagnosis, adjusting for age, pharmaceutically treated hypertension, hypercholesterolemia, and diabetes mellitus in the year prior to cancer diagnosis, tumor stage, and cancer treatment. RESULTS: During the 13-year follow-up period, 193 (3%) breast cancer survivors developed CVD. Women pharmaceutically treated for anxiety in the year prior to their cancer diagnosis had a 48% increased hazard for CVD [HR = 1.48; 95% CI 1.05-1.08] after full adjustment. This association was restricted to breast cancer survivors who were 65 years or younger. Depression was not associated with CVD risk [HR = 0.89; 95% CI 0.52-1.53]. Older age [HR = 1.06; 95% CI 1.05-1.08], hypertension [HR = 1.80; 95% CI 1.32-2.46], and hypercholesterolemia [HR = 1.63; 95% CI 1.15-2.33] were associated with an increased hazard for incident CVD, whereas hormone therapy [HR = 0.59; 95% CI 0.42-0.83] was protective. CONCLUSIONS: Anxiety present in the year prior to breast cancer diagnosis increases the risk of incident CVD in 1-year breast cancer survivors, after adjustment for depression, traditional cardiovascular risk factors, and clinical characteristics.

Validity of the European Society of Cardiology's Psychosocial Screening Interview in Patients With Coronary Artery Disease-The THORESCI Study.

OBJECTIVE: The aim of the study was to examine the validity of the European Society of Cardiology (ESC) psychosocial screening instrument. METHODS: A total of 508 acute (67%) or elective (33%) percutaneous coronary intervention patients (mean [standard deviation]age = 63 [10] years, 81% male) completed the ESC screening interview and established questionnaires for psychosocial risk markers, that is, depression (Patient Health Questionnaire 9), anxiety (Generalized Anxiety Disorder Questionnaire 7), type D personality (Type D Scale 14), hostility (Cook-Medley Hostility Scale 7), and marital/work stress (Maudsley Marital Quality Questionnaire 6, Effort-Reward Imbalance Scale) during or close after hospital admission. At 1-year follow-up, angina and cardiopulmonary symptoms were assessed. RESULTS: Prevalence estimates of psychosocial factors based on the ESC screener were as follows: depression (18%), anxiety (33%), negative affectivity (11%), social inhibition (41%), work stress (17%), marital stress (2%), and hostility (38%). Analysis of correspondence with validated questionnaires revealed fair to moderate agreement (depression [κ = .39], anxiety [κ = .23], type D personality [κ = .21]), regardless of percutaneous coronary intervention indication. For work and marital stress, there was poor to fair performance (κ range = .04-.24); agreement for hostility was poor (κ = -.27). A positive ESC screen for depression, anxious tension, and type D personality was associated with more angina and cardiopulmonary symptoms at follow-up (odds ratios ranging between 1.85 (95% confidence interval = 0.84-4.08) and 8.01 (95% confidence interval = 2.35-27.35). CONCLUSIONS: The ESC screener contributes to the search for a multidimensional and easy-to-use psychosocial screening instrument for cardiac patients. Although the screener, in its current form, may not be sufficiently valid to reliably detect all predefined psychosocial factors, screening scores for depression and anxiety might be useful in clinical practice. Our findings can be used for further refinement and validation of the screener.

Advanced Glycation End Product (AGE) Accumulation in the Skin is Associated with Depression: The Maastricht Study.

BACKGROUND: Depression is a highly prevalent disease with a high morbidity and mortality risk. Its pathophysiology is not entirely clear. However, type 2 diabetes is an important risk factor for depression. One mechanism that may explain this association may include the formation of advanced glycation end products (AGEs). We therefore investigated the association of AGEs with depressive symptoms and depressive disorder. In addition, we examined whether the potential association was present for somatic and/or cognitive symptoms of depression. METHODS: Cross-sectional data were used from the Maastricht Study (N = 862, mean age 59.8 ± 8.5 years, 55% men). AGE accumulation was measured with skin autofluorescence (SAF) by use of the AGE Reader. Plasma levels of protein-bound pentosidine were measured with high-performance liquid chromatography and fluorescence detection. Nε-(carboxymethyl)lysine (CML) and Nε-(carboxyethyl)lysine (CEL) were measured with ultraperformance liquid chromatography and tandem mass spectrometry. Depressive symptoms and depressive disorder were assessed by the nine-item Patient Health Questionnaire and the Mini-International Neuropsychiatric Interview. RESULTS: Higher SAF was associated with depressive symptoms (ß = 0.42, 95% CI 0.12-0.73, P = .007) and depressive disorder (OR = 1.42, 95% CI 1.04-1.95, P = .028) after adjustment for age, sex, type 2 diabetes, smoking, BMI, and kidney function. Plasma pentosidine, CML, and CEL were not independently associated with depressive symptoms and depressive disorder. CONCLUSIONS: This study shows that AGE accumulation in the skin is independently associated with higher levels of depressive symptoms and depressive disorder. This association is present for both somatic and cognitive symptoms of depression. This might suggest that AGEs are involved in the development of depression.

Posttraumatic stress and anxiety in patients with an implantable cardioverter defibrillator: Trajectories and vulnerability factors.

BACKGROUND: Implantable cardioverter defibrillator (ICD) therapy is the first-line treatment for the primary and secondary prevention of sudden cardiac death. Despite the unequivocal medical benefits, living with an ICD may affect patients' psychological functioning and general well-being. We examined the trajectories of symptoms of posttraumatic stress disorder (PTSD) and anxiety in patients with an ICD and the vulnerability factors associated with an increased risk of symptoms of PTSD and anxiety. METHODS: A total of 249 patients were included as part of the WEB-based distress program for implantable CARdioverter dEfibrillator patients (WEBCARE) study. Data were analyzed using Latent class analyses, with trajectories of PTSD symptomatology and anxiety examined between baseline and 12 months follow-up. RESULTS: The mean age of the sample was 58.9 ± 9.8, with the majority being male (82%). Latent Class analyses (LatentGOLD) revealed four classes with respect to PTSD symptomatology, and three classes of patients with respect to anxiety. Younger age, increased depression score at baseline, and Type D personality were all associated with increased vulnerability for posttraumatic stress and anxiety symptoms. CONCLUSION: Comparable trajectories were found for symptoms of PTSD and anxiety over time. Patients with a younger age, increased depression score at baseline, and Type D personality were especially prone to experience PTSD and anxiety symptomatology at 12 months follow-up. Due to the negative association between PTSD, anxiety, and health outcomes, it is paramount to timely identify the subset of patients who are vulnerable to experience these symptoms and provide them with personalized support.

The patient perspective on remote monitoring of patients with an implantable cardioverter defibrillator: Narrative review and future directions.

BACKGROUND: Studies have shown that remote patient monitoring (RPM) of implantable cardioverter defibrillators (ICDs) is at least comparable to in-clinic follow-up with regard to clinical outcomes and might be cost-effective, yet RPM is not standard clinical practice within Europe. Better insight into the patient perspective on RPM may aid in its acceptance, implementation, and reimbursement. This narrative review (1) summarizes existing evidence on the impact of RPM on patient-reported outcomes and (2) discusses future directions in examining the patient perspective. METHODS AND RESULTS: Literature review indicated that only five randomized trials on RPM in ICD patients included patient-reported outcomes, with inconclusive results. Observational studies show a trend toward good patient satisfaction and acceptation of RPM. Yet, results should be interpreted with caution due to a number of limitations including a potential selection bias, use of generic/nonvalidated questionnaires, relatively short follow-up durations, and a lack of subgroup identification. CONCLUSION: Although RPM seems to be safe, effective, timely, and efficient, the patient perspective has received little attention so far. The scarce evidence on patient-reported outcomes in RPM studies seems to be positive, but future trials with a follow-up of ≥12 months and validated patient-reported outcome measures are needed. The REMOTE-CIED study from our group is the first prospective randomized controlled trial primarily designed to examine the patient perspective on RPM, and is powered to identify characteristics associated with RPM satisfaction and benefit. Results are expected in 2018 and will add valuable information to the current evidence.

Perceived Cognition after Percutaneous Coronary Intervention: Association with Quality of Life, Mood and Fatigue in the THORESCI Study.

PURPOSE: Percutaneous coronary intervention (PCI) is a common invasive procedure for the treatment of coronary artery diseases. Long-term cognitive functioning after PCI and its association with health-related quality of life (HRQL) and psychological factors is relatively unknown. The aim of this study is to examine whether perceived cognitive functioning during the year after PCI is associated with HRQL over this time period, and whether mood, fatigue, and age are associated with changes in perceived cognition and HRQL. METHODS: Patients undergoing PCI (n = 384, 79% male, mean age = 63, SD = 10) were recruited in the observational Tilburg Health Outcome Registry of Emotional Stress after Coronary Intervention (THORESCI) cohort study. Perceived concentration and attention problems, HRQL, mood, and fatigue were assessed at baseline, at 1-month and 12-month follow-up. RESULTS: General linear mixed modeling analysis showed that across time, between- and within-subject differences in perceived concentration problems were associated with a reduced HRQL in all domains independent of clinical and demographic covariates. Only a part of this association could be explained by negative mood, fatigue, and older age. Similar findings were found for between-subject differences in perceived attention problems. CONCLUSIONS: Between-subject differences and within-subject changes in perceived cognition in PCI patients were strongly associated with HRQL across time, such that poorer perceived cognition was associated with poorer HRQL, independent of demographic and clinical variables. Most of the associations were also independent of mood and fatigue. The results should increase the awareness of clinicians for the role of cognition in the cardiac rehabilitation and recovery post-PCI.

Personality, health behaviors, and quality of life among colorectal cancer survivors: Results from the PROFILES registry.

PURPOSE: There is a paucity of research looking into the relationship between personality and health behaviors among cancer survivors. The aim of this study was to investigate whether Type D personality and its two constituent components, negative affectivity (NA) and social inhibition (SI), are associated with health behaviors, quality of life (QoL), and mental distress among colorectal cancer (CRC) survivors. METHODS: A population-based study was conducted among 2,620 CRC patients diagnosed between 2000 and 2009, who completed measures of personality (DS14), health behaviors, QoL (EORTC QLQ-C30), and mental distress (hospital anxiety and depression scale). RESULTS: Personality was not associated with body mass index or smoking. Those scoring high on NA (with or without SI) were more often nondrinkers and less physically active compared to those scoring high on neither or only SI. Personality (high scores NA) and health behaviors (inactivity) were independently associated with poor QoL and mental distress. CONCLUSIONS: CRC survivors with high scores on NA are at risk of being inactive and have worse health outcomes.

Determinants of Dyspnea in Chronic Heart Failure.

BACKGROUND: Dyspnea is a hallmark symptom of heart failure (HF), associated with impaired functional capacity and quality of life. The experience of dyspnea is multifactorial and may originate from different sources. This study set out to examine the relative importance of potential contributors to dyspnea, ie, disease severity, inflammation and psychologic distress in a large prospective cohort of chronic HF patients. This study further aimed to examine the differential influence of cognitive and somatic symptoms of psychologic distress. METHODS AND RESULTS: Dyspnea complaints (Health Complaints Scale), demographic and clinical variables, and psychologic factors (ie, depression, anxiety, and Type D personality) were assessed in 464 HF patients (mean age 66.0 y, 70% men) at baseline and 1-year follow-up. Inflammatory markers (ie, tumor necrosis factor [TNF] α, interleukin [IL] 6, IL-10, soluble TNF receptors 1 and 2) were also assessed at both time points in a subsample (n = 247). Linear mixed modeling analysis with maximum likelihood estimation showed that when determinant clusters were entered separately, comorbid chronic obstructive pulmonary disease (COPD) was significantly associated with dyspnea complaints (P = .039), as were depression (P < .001) and anxiety (P < .001), whereas inflammation did not significantly affect dyspnea complaints. When all determinant clusters and covariates were entered together, results showed that body mass index (P = .013), COPD (P = .034), age (P = .005), depression (P < .001), and anxiety (P < .001) were significant independent associates of dyspnea complaints. Somatic depressive and somatic anxiety symptoms were responsible for these latter associations. CONCLUSIONS: The experience and report of dyspnea in HF is determined foremost by somatic symptoms of psychologic distress, being of older age, being overweight, and having comorbid COPD, with disease severity and systemic inflammation levels playing an ancillary role. These findings suggest that psychologic distress should be considered when treating dyspnea complaints in patients with HF.

Psychological Determinants of Heart Failure Self-Care: Systematic Review and Meta-Analysis.

OBJECTIVE: Psychological distress has been associated with poor outcomes in patients with chronic heart failure (HF), which is assumed to be partly due to poor HF self-care behavior. This systematic review and meta-analysis describes the current evidence concerning psychological determinants of self-care in patients with chronic HF. METHODS: Eligible studies were systematically identified by searching electronic databases PubMed, PsycINFO, and the Conference Proceedings Citation Index (Web of Science) for relevant literature (1980-October 17, 2014). Study quality was assessed according to the level of risk of bias. Quantitative data were pooled using random-effects models. RESULTS: Sixty-five studies were identified for inclusion that varied considerably with respect to sample and study characteristics. Risk of bias was high in the reviewed studies and most problematic with regard to selection bias (67%). Depression (r = -0.19, p < .001), self-efficacy (r = 0.37, p < .001), and mental well-being (r = 0.14, p = .030) were significantly associated with self-reported self-care. Anxiety was not significantly associated with either self-reported (r = -0.18, p = .24) or objective self-care (r = -0.04, p = .79), neither was depression associated with objectively measured medication adherence (r = -0.05, p = .44). CONCLUSIONS: Psychological factors (depression, self-efficacy, and mental well-being) were associated with specific self-care facets in patients with chronic HF. These associations were predominantly observed with self-reported indices of self-care and not objective indices. Methodological heterogeneity and limitations preclude definite conclusions about the association between psychological factors and self-care and should be addressed in future research.

Depressive symptoms and all-cause mortality in people with type 2 diabetes: a focus on potential mechanisms.

BACKGROUND: Depression has been associated with increased all-cause mortality in people with type 2 diabetes. AIMS: To test whether anhedonia, dysphoria and anxiety are differentially associated with all-cause mortality and examine symptom-specific behavioural or pathophysiological mechanisms. METHOD: A total of 1465 people completed the Edinburgh Postnatal Depression Scale in 2005 and were followed until death or 31 December 2010. Cox regression analyses compared survival time for people with a low v. high baseline dysphoria/anhedonia/anxiety score and identified mediating mechanisms. RESULTS: After a mean follow-up of 1878 days (s.d. = 306), 139 participants had died. At all time points, people with anhedonia had an almost twofold increased mortality risk compared with those without anhedonia. Physical activity met criteria for mediation. Symptoms of dysphoria and anxiety were not associated with survival time. CONCLUSIONS: Symptoms of anhedonia predicted shorter survival time, whereas dysphoria/anxiety did not. Mechanistic pathways, in particular physical activity, should be explored further.
