Abstract
Despite the significant scientific advancement in deciphering the "deaths of despair" narrative, most relevant studies have focused on drug-, alcohol-, and suicide-related (DAS) deaths. This study directly investigated despair as a determinant of death and the temporal variation and racial heterogeneity among individuals. We used psychological distress (PD) as a proxy for despair and drew data from the US National Health Interview Survey-Linked Mortality Files 1997 to 2014, CDC (Centers for Disease Control and Prevention) Multiple Cause of Death database 1997 to 2014, CDC bridged-race population files 1997 to 2014, Current Population Survey 1997 to 1999, and the American Community Survey 2000 to 2014. We used Cox proportional hazards models to estimate mortality hazard ratios of PD and compared age-standardized PD- and DAS-related mortality rates by race/ethnicity and over time. We found that while Whites had a lower prevalence of PD than Blacks and Hispanics throughout the whole period, they underwent distinctive increases in PD-related death and have had a higher PD-related mortality rate than Blacks and Hispanics since the early 2000s. This was predominantly due to Whites' relatively high and increasing vulnerability to PD less the prevalence of PD. Furthermore, PD induced a more pervasive mortality consequence than DAS combined for Whites and Blacks. In addition, PD- and DAS-related deaths displayed a concordant trend among Whites but divergent patterns for Blacks and Hispanics. These findings suggest that 1) DAS-related deaths underestimated the mortality consequence of despair for Whites and Blacks but overestimated it for Hispanics; and 2) despair partially contributed to the DAS trend among Whites but probably not for Blacks and Hispanics.

Abstract
Level of corticosterone (CORT), which is a predominant glucocorticoid in birds, has become the main indicator for assessing the stress level of birds in ecological studies. Feather corticosterone (CORTf) provides information about corticosterone levels during feather growth, however, the underlying causes of individual variation of CORTf between individuals and individual persistency of CORTf are not yet fully understood. Therefore, this study addresses individual consistency in CORTf and the association of variation in CORTf with behaviour that results in damage to tail feathers. We studied relations between CORTf, plasma CORT, and behaviour in wild-caught male greenfinches in captivity. CORTf in wild-grown feathers correlated positively with CORTf in lab-grown feathers. CORTf levels were about 20% lower in lab-grown feathers than in those grown in the wild. Four birds that died in captivity had significantly higher average CORTf levels in wild-grown feathers than the survivors. Plasma CORT levels of two measurements taken in the lab seven days apart correlated positively, however, no correlations between plasma CORT and CORTf were found. In order to study the link between CORTf and behaviour, the extent of tail damage from flapping against cage bar was assessed. Contrary to our prediction, birds with higher CORTf had less tail damage. This study adds to the evidence that CORTf levels can be considered as informative markers of some persistent component of individual phenotypic quality that can predict survival under standardized laboratory conditions.

Abstract
BACKGROUND Psychological stress is recognized as a major risk factor for a range of non-communicable diseases and possibly mortality. The extent to which the type and timing of stress exposure influences mortality, and potential differences between genders, remains unknown. OBJECTIVE To examine the association between early-life and recent stressful experiences and mortality risk in later life, and to determine possible gender differences in these associations. METHOD Data were obtained from 2152 French community-dwelling participants (aged ≥65). Questionnaires were used to evaluate recent stress, as well as retrospective reporting of childhood adversity. Mortality status was determined through death registries. Adjusted Cox proportional hazards models were used to determine the association between stress and 16-year mortality risk. RESULTS Over a mean 12.9 years, 850 people died. Having a childhood home environment with very serious conflicts was associated with a 54% increased mortality risk (95%CI:1.21-1.96), and childhood abuse/maltreatment with a 34% increased risk (95% CI:1.05-1.70). For females, specific childhood events (serious illness HR:1.91, 95%CI:1.40-2.60; war/natural disaster HR:1.47, 95%CI:1.14-1.88) and the number of events (≥5 adverse events HR:1.91, 95%CI:1.25-2.32), also increased mortality risk. In terms of recent events, mortality risk increased by 66% (95%CI:1.39-2.00) in participants reporting a recent serious illness or physical trauma and by 86% for those reporting problems with the police/justice (95%CI:1.05-3.30). Among males specifically, mortality risk also increased with major financial problems (HR:1.92, 95%CI:1.14-3.21), and when they had a relative with a serious illness (HR:1.26, 95%CI:1.01-1.55). CONCLUSIONS Stressful life experiences are associated with all-cause mortality however the associations varied between early-life adversities and recent stress, and were different across the genders. Among females, certain types of childhood adversity continue to predict mortality risk in later life, while in males specific recent stress significantly increased mortality risk.

Abstract
The design of experimental protocols that use animal models to assess the impact of a stress on a population or to determine the life span expectancy impact can be time-consuming due to the need for direct observations of dead and living animals. These experiments are usually based on the detectable activity of animals such as food intake or mobility and can sometimes produce either under- or overestimated results. The tardigrade Hypsibius exemplaris is an emerging model for the evolutionary biology of the tardigrade phylum because of its convenient laboratory breeding and the recent introduction of new molecular tools. In this report, we describe the use of a new fluorescent dye that can specifically stain dead tardigrades. Furthermore, we also monitored the absence of a toxic side effect of the death-linked fluorescent dye on tardigrade populations. Finally, we conclude that tardigrade experiments that require survival counting of the Hypsibius exemplaris species can be greatly improved by using this technique in order to limit underestimation of alive animals.

Abstract
Multiple studies have confirmed a seemingly paradoxical finding that family caregivers have lower mortality rates than comparable samples of noncaregivers. Caregivers are often also found to report more symptoms of depression and higher stress levels, but psychological distress and mortality are rarely examined in the same study. This study tests a possible mechanism for the mortality effect by applying a theoretical model that posits psychological and physiological stress-buffering benefits from prosocial helping behaviors. Participants in the population-based REasons for Geographic and Racial Differences in Stroke (REGARDS) study included 3,580 family caregivers who were individually matched to 3,580 noncaregivers on 15 demographic, health history, and health behavior variables using a propensity score matching algorithm. Baseline measures of depressive symptoms and perceived stress levels were also collected. The results indicated that caregivers reported significantly more depressive symptoms and higher perceived stress levels than propensity-matched noncaregivers (ps < .0001). However, consistent with our previous analysis (Roth et al., 2013), an analysis of 7-year survival rates showed that caregivers had a 16.5% lower mortality rate than noncaregivers (hazard ratio = 0.835, 95% CI = 0.719, 0.970). Significant caregiving*psychological distress interaction effects supported the stress-buffering hypothesis. Both depressive symptoms and perceived stress scores were significant predictors of mortality for the matched noncaregivers (ps < .0001), but not for the caregivers (ps > .49). Family caregiving appears to be similar to other prosocial helping behaviors in that it provides stress-buffering adaptations that ameliorate the impact of stress on major health outcomes such as mortality.

Abstract
Background Recent research has suggested that increases in mortality among middle-aged US Whites are being driven by suicides and poisonings from alcohol and drug use. Increases in these 'despair' deaths have been argued to reflect a cohort-based epidemic of pain and distress among middle-aged US Whites. Methods We examine trends in all-cause and cause-specific mortality rates among younger and middle-aged US White men and women between 1980 and 2014, using official US mortality data. We estimate trends in cause-specific mortality from suicides, alcohol-related deaths, drug-related deaths, 'metabolic diseases' (i.e. deaths from heart diseases, diabetes, obesity and/or hypertension), and residual deaths from extrinsic causes (i.e. causes external to the body). We examine variation in mortality trends by gender, age and cause of death, and decompose trends into period- and cohort-based variation. Results Trends in middle-aged US White mortality vary considerably by cause and gender. The relative contribution to overall mortality rates from drug-related deaths has increased dramatically since the early 1990s, but the contributions from suicide and alcohol-related deaths have remained stable. Rising mortality from drug-related deaths exhibit strong period-based patterns. Declines in deaths from metabolic diseases have slowed for middle-aged White men and have stalled for middle-aged White women, and exhibit strong cohort-based patterns. Conclusions We find little empirical support for the pain- and distress-based explanations for rising mortality in the US White population. Instead, recent mortality increases among younger and middle-aged US White men and women have likely been shaped by the US opiate epidemic and an expanding obesogenic environment.

Abstract
BACKGROUND The theory that posthospitalization stress might increase the risk of postdischarge complications has never been investigated. OBJECTIVE To assess whether serum levels of stress biomarkers at discharge are associated with readmission and death after an acute-care hospitalization. DESIGN We prospectively included 346 patients aged ≥50 years admitted to the department of general internal medicine at a large community hospital between April 8, 2013 and September 23, 2013. We measured the serum levels of several biomarkers at discharge: midregional pro-adrenomedullin, copeptin, cortisol, and prolactin. All patients were followed for up to 90 days after discharge (none was lost to follow-up). The main outcome was first unplanned readmission or death within 30 days after hospital discharge. We assessed the additional value of biomarkers to 2 validated readmission prediction scores: the LACE index (Length of stay, Admission Acuity, Charlson Comorbidity Index, and number of Emergency department visits within preceding 6 months) and the HOSPITAL score (Hemoglobin level at discharge, discharge from Oncology service, Sodium level at discharge, any Procedure performed during index hospitalization, Index admission Type, number of Admissions within preceding 12 months, and Length of stay). RESULTS Forty patients (11.6%) had a 30-day unplanned readmission or death. High serum copeptin and cortisol levels were associated with an increase in the odds of unplanned readmission or death (odds ratios [95% confidence interval] 2.69 [1.29-5.64] and 3.43 [1.36, 8.65], respectively). We found no significant association with midregional pro-adrenomedullin or prolactin. Furthermore, these stress biomarkers increased the performance of two readmission prediction scores (LACE index and HOSPITAL score). CONCLUSION High serum levels of copeptin and cortisol at discharge were independently associated with 30-day unplanned readmission or death, supporting a possible negative effect of hospitalization stress during the postdischarge period. Stress biomarkers improved the performance of prediction models and therefore could help better identify high-risk patients.

Abstract
OBJECTIVE To assess the associations of perceived discrimination and cardiovascular (CV) outcomes in African Americans (AAs) in the Jackson Heart Study. PATIENTS AND METHODS In 5085 AAs free of clinical CV disease at baseline enrolled in the Jackson Heart Study from September 26, 2000, through March 31, 2004, and followed through 2012, associations of everyday discrimination (frequency of occurrences of perceived unfair treatment) and lifetime discrimination (perceived unfair treatment in 9 life domains) with CV outcomes (all-cause mortality, incident coronary heart disease [CHD], incident stroke, and heart failure [HF] hospitalization) were examined using Cox proportional hazards regression models. RESULTS Higher levels of everyday and lifetime discrimination were more common in participants who were younger and male and had higher education and income, lower perceived standing in the community, worse perceived health care access, and fewer comorbidities. Before adjustment, higher levels of everyday and lifetime discrimination were associated with a lower risk of all-cause mortality, incident CHD, stroke, and HF hospitalization. After adjustment for potential confounders, we found no association of everyday and lifetime discrimination with incident CHD, incident stroke, or HF hospitalization; however, a decrease in all-cause mortality with progressively higher levels of everyday discrimination persisted (hazard ratio per point increase in discrimination measure, 0.90; 95% CI, 0.82-0.99; P=.02). The unexpected association of everyday discrimination and all-cause mortality was partially mediated by perceived stress. CONCLUSION We found no independent association of perceived discrimination with risk of incident CV disease or HF hospitalization in this AA population. An observed paradoxical negative association of everyday discrimination and all-cause mortality was partially mediated by perceived stress.

Abstract
CONTEXT Although dying peacefully is considered an important outcome of high-quality palliative care, large-scale quantitative research on dying peacefully and the factors associated with a peaceful death is lacking. OBJECTIVES To gain insight into how many residents with dementia in long-term care facilities die peacefully, according to their relatives, and whether that assessment is correlated with observed physical and psychological distress. METHODS This was a retrospective cross-sectional study of deceased nursing home residents in a representative sample of long-term care facilities in Flanders, Belgium (2010). Structured post-mortem questionnaires were completed by relatives of the resident, who were asked to what extent they agreed that the resident "appeared to be at peace" during the dying process. Spearman correlation coefficients gave the correlations between physical and psychological distress (as measured using the Symptom Management at the End of Life with Dementia and Comfort Assessment in Dying at the End of Life with Dementia scales) and dying peacefully (as measured using the Quality of Dying in Long Term Care instrument). RESULTS The sample comprised 92 relatives of deceased residents with dementia. In 54% of cases, relatives indicated that the resident died peacefully. Weak-to-moderate correlations (0.2-0.57) were found between dying peacefully and physical distress in the last week of life. Regarding psychological distress, weak-to-moderate correlations were found for both the last week (0.33-0.44) and last month of life (0.28-0.47). CONCLUSION Only half of the residents with dementia died peacefully as perceived by their relatives. Relatives' assessment of whether death was peaceful is related to both physical and psychological distress. Further qualitative research is recommended to gain more in-depth insights into the aspects on which relatives base their judgment of dying peacefully.

Abstract
Psychiatric disorders themselves--and not only the known psychotropic agents--lead to enhanced psychic and somatic morbidity, and not only as a so-called psychic reaction. Psychiatric disorders such as depression, anxiety disorders and schizophrenia are diseases with a high prevalence and incidence in most countries, and they are life-threatening because they induce--besides suicidality--also many somatic diseases such as coronary arte- riosclerotic syndrome and diabetes. As a result, they have an--often indirect--effect on mortality. In the future, studies should give greater attention to the underlying neurobiological mechanisms. True "psychosomatic medicine" consists of determining the combined biological effect of psychic and somatic factors and their interactions in greater detail.

Abstract
We investigated whether hassles mediated the effect of life events on mortality in a sample of 1293 men (Mage=65.58, SD=7.01), participants in the VA Normative Aging Study. We utilized measures of stressful life events (SLE) and hassles from 1989 to 2004, and men were followed for mortality until 2010. For life events and hassles, previous research identified three and four patterns of change over time, respectively, generally indicating low, moderate, and high trajectories, with one moderate, non-linear pattern for hassles (shallow U curve). Controlling for demographics and health behaviors, we found that those with moderate SLE trajectories (38%) more likely to die than those with low SLE trajectories, HR=1.42, 95% CI [1.16, 3.45]. Including the hassles classes showed that those with the moderate non-linear hassles trajectory were 63% more likely to die than those with low hassles trajectory, HR=1.63, 95% CI [1.19, 2.23], while those with consistently high hassles trajectory were over 3 times more likely to die, HR=3.30, 95% CI [1.58, 6.89]. However, the HR for moderate SLE trajectory decreased only slightly to 1.38, 95% CI [1.13, 1.68], suggesting that the two types of stress have largely independent effects on mortality. Research is needed to determine the physiological and behavioral pathways through which SLE and hassles differentially affect mortality.

Abstract
PURPOSE Physical inactivity and obesity are major U.S. health concerns. Hispanics have higher rates of obesity and lower incidence of meeting physical activity (PA) recommendations, however most studies on PA focus on non-Hispanic Whites. This study examined type and amount of physical activities, and their relationship to age, BMI, employment, and stress in adult female Hispanics. DATA SOURCES Sixty-three female Hispanics (mean age 34 years, SD = 10.5) were recruited in the Miami community. By BMI, of 47 women reporting both weight and height, 8.5% were underweight, 38.3% were normal weight, 27.2% were overweight, and 26.0% were obese. Women completed two instruments measuring PA and two measuring stress. CONCLUSIONS Attitudes toward PA were positive; greatest concerns were job security and finances not exercise. Leisure walking (14.3%) was the most common type of PA followed by activities watching TV (32.8%) and using video games (32.8%). Women with greater stress had higher BMIs and were less physically active (p < .05). IMPLICATIONS FOR PRACTICE In this sample, exercise was not a main priority although 53% were overweight/obese. Stress related to employment and finances was a major concern. Interventions on stress reduction and incorporating exercise within their daily lives are important strategies.

Abstract
Perceived stress is associated with poor health outcomes including negative affect, increased susceptibility to the common cold and cardiovascular disease; the consequences of perceived stress for mortality, however, have received less attention. This study characterizes the relationship between perceived stress and 11-year mortality in a population of Taiwanese adults aged 53+ years. Using the Survey of Health and Living Status of the Near Elderly and Elderly of Taiwan, we calculated a composite measure of perceived stress based on six items pertaining to the health, financial situation, and occupation of the respondents and their families. Proportional hazard models were used to determine whether perceived stress predicted mortality. After adjusting for sociodemographic factors only, we found that a one standard deviation increase in perceived stress was associated with a 19% increase in all-cause mortality risk during the 11-year follow-up period (hazard ratio, HR = 1.19, 95% confidence interval, CI 1.13-1.26). The relationship was greatly attenuated when perceptions of stress regarding health were excluded, and was not significant after adjusting for medical conditions, mobility limitations and depressive symptoms. We conclude that the association between perceived stress and mortality is explained by an individual's current health; however, our data do not allow us to distinguish between two possible interpretations of this conclusion: (a) the relationship between perceived stress and mortality is spurious, or (b) poor health acts as the mediator.

Abstract
CONTEXT Limited research has taken place examining family conferences (FCs) with patients with advanced cancer and their caregivers in the palliative care setting. OBJECTIVES To characterize the FCs involving cancer patients in a palliative care unit at a comprehensive cancer center and examine the effects of patient participation on emotional expression by the participants and end-of-life discussions. METHODS A data collection sheet was completed immediately after 140 consecutive FCs that documented the number of participants, caregiver demographics, expressions of emotional distress, dissatisfaction with care, and the topics discussed. Patient demographics and discharge disposition also were collected. RESULTS Seventy (50%) patients were female, 64 (46%) were white, and 127 (91%) had solid tumors. Median age of patients was 59 years. Patients participated in 68 of 140 FCs (49%). Primary caregivers (n = 140) were female (66%), white (49%), and the spouse/partner (59%). Patients verbalized distress frequently (73%). Primary caregivers' verbal expression of emotional distress was high (82%) but not significantly affected by patient presence (82% vs. 82%, P = 0.936). Verbal expressions of emotional distress by other family members were more common when patients were absent (87%) than when present (73%), P = 0.037. Questions concerning advance directives (21%), symptoms anticipated at death (31%), and caregiver well-being (29%) were infrequent. Patient presence was significantly associated with increased discussions regarding goals of care (P = 0.009) and decreased communication concerning prognosis (P = 0.004) and what symptoms dying patients may experience (P < 0.001). CONCLUSION There was a high frequency of expression of emotional distress by patients and family members in FCs. Patient participation was significantly associated with decreased verbal emotional expression by family members but not the primary caregiver and was associated with fewer discussions regarding prognosis and what dying patients may experience.

Abstract
Certain fatal casualties or psychic decompensations occur significantly more frequently on birthdays and other biographically important anniversaries. Analyses of life tables have clearly confirmed this clinical evidence. The stress model and the concept of "anniversary reactions" are the two most convincing explanations for these associations. Both concepts and meaningful opportunities for prevention of "anniversary reactions" will be presented.

Abstract
CONTEXT Sedation at the end of life, regardless of the nomenclature, is an increasingly debated practice at both clinical and bioethical levels. However, little is known about the characteristics and trends in scientific publications in this field of study. OBJECTIVES This article presents a bibliometric analysis of the scientific publications on continuous sedation until death. METHODS Four electronic databases (MEDLINE, PubMed, Embase, and PsycINFO®) were searched for the indexed material published between 1945 and 2011. This search resulted in bibliographic data of 273 published outputs that were analyzed using bibliometric techniques. RESULTS Data revealed a trend of increased scientific publication from the early 1990s. Published outputs, diverse in type (comments/letters, articles, reviews, case reports, editorials), were widely distributed across 94 journals of varying scientific disciplines (medicine, nursing, palliative care, law, ethics). Most journals (72.3%) were classified under Medical and Health Sciences, with the Journal of Pain and Symptom Management identified as the major journal in the field covering 12.1% of the total publications. Empirical research articles, mostly of a quantitative design, originated from 17 countries. Although Japan and The Netherlands were found to be the leaders in research article productivity, it was the U.K. and the U.S. that ranked top in terms of the quantity of published outputs. CONCLUSION This is the first bibliometric analysis on continuous sedation until death that can be used to inform future studies. Further research is needed to refine controversies on terminology and ethical acceptability of the practice, as well as conditions and modalities of its use.

Abstract
BACKGROUND Ischemic heart disease (IHD) is the leading cause of morbidity and mortality in the industrialized world. Recent research evidence suggests that psychosocial distress has been implicated as both a precursor to IHD and a significant risk factor for death in those with established IHD. According to WHO, psychosocial distress will be the most harmful risk factor for the development of IHD in the near future. Some experts have underlined the importance of the psychosocial distress of economic and political reforms as the main reason for the IHD mortality crisis in Russia in the 1990s. The aim of the present study was to estimate the effect of psychosocial distress on IHD mortality rate in Russia. SUBJECTS AND METHODS Trends in age-adjusted, sex-specific suicide (as an integral indicator for psychosocial distress) and IHD mortality rate in Russia from 1965 to 2005 were analyzed employing a distributed lags analysis in order to assess the bivariate relationship between the two time series. RESULTS Time series analysis indicates the presence of a statistically significant association between the two time series for males at lags 0 and females at lags 0 and 1. CONCLUSIONS These findings suggest that the Russian IHD mortality crisis is most likely to have been precipitated by the psychosocial distress imposed by rapid societal transformation. The experience of Russia should serve as an example of how societal-level change can influence the health of a population.

Abstract
BACKGROUND AND PURPOSE To investigate the association of psychosocial distress with risk of stroke mortality and incident stroke in older adults. METHODS Data were from the Chicago Health and Aging Project, a longitudinal population-based study conducted in 3 contiguous neighborhoods on the south side of Chicago, IL. Participants were community-dwelling black and non-Hispanic white adults, aged 65 years and older (n=4120 for stroke mortality; n=2649 for incident stroke). Psychosocial distress was an analytically derived composite measure of depressive symptoms, perceived stress, neuroticism, and life dissatisfaction. Cox proportional hazards models examined the association of distress with stroke mortality and incident stroke over 6 years of follow-up. RESULTS Stroke deaths (151) and 452 incident strokes were identified. Adjusting for age, race, and sex, the hazard ratio (HR) for each 1-SD increase in distress was 1.47 (95% confidence interval [CI]=1.28-1.70) for stroke mortality and 1.18 (95% CI=1.07-1.30) for incident stroke. Associations were reduced after adjustment for stroke risk factors and remained significant for stroke mortality (HR=1.29; 95% CI=1.10-1.52) but not for incident stroke (HR=1.09; 95% CI=0.98-1.21). Secondary analyses of stroke subtypes showed that distress was strongly related to incident hemorrhagic strokes (HR=1.70; 95% CI=1.28-2.25) but not ischemic strokes (HR=1.02; 95% CI=0.91-1.15) in fully adjusted models. CONCLUSIONS Increasing levels of psychosocial distress are related to excess risk of both fatal and nonfatal stroke in older black and white adults. Additional research is needed to examine pathways linking psychosocial distress to cerebrovascular disease risk.

Abstract
BACKGROUND/PURPOSE Controversy exists in the literature regarding whether dentists with multiple occupational exposures suffer from premature mortality. A cohort mortality study was conducted to evaluate the survival outcome and determine if potential exposure to harmful agents leads to premature mortality among dentists. METHODS Using the Life Table Analysis System, we calculated standardized mortality ratios (SMRs) for a cohort of 11,700 dentists affiliated with the Taiwan Dental Association. These dentists were followed from 1985-2009. Reference rates were derived from cause-, gender-, and age-specific mortality rates of the general population of Taiwan and 18,664 Taiwanese internists, who were considered to be more socioeconomically proximal to dentists. A Cox proportional hazard model was also constructed to determine multiple risk factors associated with mortality. RESULTS Compared with the general population, dentists in Taiwan consistently demonstrated reduced from all-cause mortality. However, compared with internists, significant and excess mortality were observed in dentists for overall mortality (SMR=1.13; 95% confidence interval [CI]=1.00-1.26), drowning (SMR=6.62; 95% CI=2.15-15.45), and heart diseases (SMR=1.66; 95% CI=1.22-2.21). After adjusting for other risk factors, the Cox model showed an increased hazard ratio of 1.17 (95% CI=1.01-1.37) for dentists. CONCLUSION Taiwanese dentists demonstrated significant elevated SMRs for overall causes, drowning, and heart diseases. Careful precaution should be taken to reduce these trends. Future studies are also needed for in-depth exploration of the mechanisms regarding how professional stress and exposure contribute to the increased risk of mortality in Taiwanese dentists.

Abstract
BACKGROUND There is compelling evidence that psychological factors may have the same or even greater impact on the possibility of adverse events on cardiac diseases (CD) than other traditional clinical risk factors. Anxiety and depression are predictors of short- and long-term adverse outcomes, increased risk for higher rates of in-hospital complications, re-infarction, malignant arrhythmias, and mortality in CD patients. Despite researchers finding that cognitive behavior therapy (CBT) reduced depressive and anxiety symptoms, the fact that such results are maintained only in the short term and the lack of maintenance of the long-term affects the absence of changes in lifestyles, preventing the possibility of a wide generalization of results. Recently wellbeing therapy (WBT) has been proposed as a useful approach to improve healthy lifestyle behaviors and reduce psychological distress. METHODS/DESIGN The present randomized controlled study will test WBT, in comparison with CBT, as far as the reduction of symptoms of depression, anxiety and psychological distress, and the improvement of lifestyle behaviors and quality of life in cardiac patients are concerned. Moreover, innovations in communication technologies allow patients to be constantly followed in real life. Therefore WBT based on personalized mobile technology will allow the testing of its effectiveness in comparison with usual WBT. DISCUSSION The present study is a large outpatient study on the treatment of co-morbid depression, anxiety, and psychological distress in cardiac patients. The most important issues of this study are its randomized design, the focus on promotion of health-related behaviors, and the use of innovative technologies supporting patients' wellbeing in real life and in a continuous way. First results are expected in 2012. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01543815.

Abstract
OBJECTIVE To quantify the link between lower, subclinically symptomatic, levels of psychological distress and cause-specific mortality in a large scale, population based study. DESIGN Individual participant meta-analysis of 10 large prospective cohort studies from the Health Survey for England. Baseline psychological distress measured by the 12 item General Health Questionnaire score, and mortality from death certification. PARTICIPANTS 68,222 people from general population samples of adults aged 35 years and over, free of cardiovascular disease and cancer, and living in private households in England at study baseline. MAIN OUTCOME MEASURES Death from all causes (n = 8365), cardiovascular disease including cerebrovascular disease (n = 3382), all cancers (n = 2552), and deaths from external causes (n = 386). Mean follow-up was 8.2 years (standard deviation 3.5). RESULTS We found a dose-response association between psychological distress across the full range of severity and an increased risk of mortality (age and sex adjusted hazard ratio for General Health Questionnaire scores of 1-3 v score 0: 1.20, 95% confidence interval 1.13 to 1.27; scores 4-6: 1.43, 1.31 to 1.56; and scores 7-12: 1.94, 1.66 to 2.26; P<0.001 for trend). This association remained after adjustment for somatic comorbidity plus behavioural and socioeconomic factors. A similar association was found for cardiovascular disease deaths and deaths from external causes. Cancer death was only associated with psychological distress at higher levels. CONCLUSIONS Psychological distress is associated with increased risk of mortality from several major causes in a dose-response pattern. Risk of mortality was raised even at lower levels of distress.

Abstract
CONTEXT Evidence for the association of cortisol with mortality or disease events is mixed, possibly due to a failure to consider diurnal cortisol patterns. OBJECTIVE Our objective was to examine the association of diurnal cortisol patterns throughout the day with cardiovascular and noncardiovascular mortality in a community-dwelling population. DESIGN This was a prospective cohort study among 4047 civil servants, the Whitehall II study, United Kingdom. We measured diurnal cortisol patterns in 2002-2004 from six saliva samples obtained over the course of a normal weekday: at waking, +30 min, +2.5 h, +8 h, +12 h, and bedtime. Participants were subsequently followed for all-cause and cause-specific mortality until January 2010. PARTICIPANTS Participants included 4047 men and women aged 61 yr on average at baseline. OUTCOMES We assessed all-cause, cardiovascular, and noncardiovascular death. RESULTS There were 139 deaths, 32 of which were deaths due to cardiovascular disease, during a mean follow-up period of 6.1 yr. Flatter slopes in cortisol decline across the day were associated with increased risk of all-cause mortality (hazard ratio for 1 sd reduction in slope steepness 1.30; 95% confidence interval (CI) = 1.09-1.55). This excess mortality risk was mainly driven by an increased risk of cardiovascular deaths (hazard ratio = 1.87; 95% confidence interval = 1.32-2.64). The association with cardiovascular deaths was independent of a wide range of covariates measured at the time of cortisol assessment. There was no association between morning cortisol, the cortisol awakening response, and mortality outcomes. CONCLUSIONS These findings demonstrate, for the first time, the relationship between a flatter slope in cortisol levels across the day and an increased risk of cardiovascular disease mortality in a nonclinical population.

Abstract
The US imprisonment rate has increased dramatically since the mid-1970s, precipitating tremendous interest in the consequences of having ever been imprisoned for the marginal men for whom contact with prisons and jails has become commonplace. The article by Spaulding et al. in this issue of the Journal (Am J Epidemiol. 2011;173(5):479-487) makes a substantial contribution to research in this area by demonstrating for the first time that the small short-term benefits of imprisonment with regard to mortality risk are far outweighed by the much larger long-term mortality costs of having ever been imprisoned. Yet it remains unclear whether contact with the penal system causes the associations therein. In this commentary, the author addresses some of the obstacles to causal inference that exist in this research area and highlights one way to overcome them. He then suggests that future research might focus on 1) the consequences of mass imprisonment for health inequities among adult men and 2) the spillover effects of mass imprisonment for persons who are also affected by the penal system-the families, friends, and communities prisoners leave behind.

Abstract
Oxytocin (Oxt) and the Oxt receptor (Oxtr) are implicated in the onset of maternal behavior in a variety of species. Recently, we developed two Oxtr knockout lines: a total body knockout (Oxtr-/-) and a conditional Oxtr knockout (OxtrFB/FB) in which the Oxtr is lacking only in regions of the forebrain, allowing knockout females to potentially nurse and care for their biological offspring. In the current study, we assessed maternal behavior of postpartum OxtrFB/FB females toward their own pups and maternal behavior of virgin Oxtr-/- females toward foster pups and compared knockouts of both lines to wildtype (Oxtr+/+) littermates. We found that both Oxtr-/- and OxtrFB/FB females appear to have largely normal maternal behaviors. However, with first litters, approximately 40% of the OxtrFB/FB knockout dams experienced high pup mortality, compared to fewer than 10% of the Oxtr+/+ dams. We then went on to test whether or not this phenotype occurred in subsequent litters or when the dams were exposed to an environmental disturbance. We found that regardless of the degree of external disturbance, OxtrFB/FB females lost more pups on their first and second litters compared to wildtype females. Possible reasons for higher pup mortality in OxtrFB/FB females are discussed.

Abstract
BACKGROUND Job strain may be associated with various diseases and increased mortality but there is little data available from prospective studies with long-term follow-up. OBJECTIVE To assess the effect of heat exposure followed by severe job strain on blood pressure, heart rate and mortality. DESIGN Prospective 19-year observational study (1982-2000) of a cohort of employees in a ferry alloy plant undergoing two economical crises. The participants were 218 healthy males aged 30-59 years. MEASUREMENTS Annual standardized measurements of blood pressure, heart rate, serum cholesterol and registration of morbidity and mortality. RESULTS Heat-exposed men (n = 25) and non-heat-exposed men (n = 193) had unchanged blood pressure from 1982 to 1984. Thereafter the plant underwent two serious economic crises, in 1985-87 and 1990-91, respectively. The first one was handled by decisions exclusively taken by the head office and included a gradual lay-off of 25% of the workers, and the second one was handled jointly between the local management, union leaders and employees and included a modest, voluntary lay-off. Thus, the two crises differed markedly in low vs high job control. Blood pressures gradually increased from 1985 to 1988 in the whole cohort until systolic blood pressure reached 15 mmHg and diastolic blood pressure 12 mmHg above baseline levels (p < 0.001). Thereafter blood pressures decreased to slightly above baseline levels and then remained unchanged for the next 5 years. However, heart rate increased from 62 +/- 12 beats/min in 1982-83 to 69 +/- 10 beats/min in 1988 (p < 0.01) and did not return to baseline. Total mortality by 31 December 2000 in the study cohort was significantly higher over the 19 years of follow-up than among age-matched, Norwegian men (p < 0.01). CONCLUSIONS If a cause-effect relationship exists between the first economical crisis in the ferry alloy plant and the concomitant rise in blood pressure, job strain had a powerful but time-limited effect on blood pressure. Since the same phenomenon was not reproduced 5 years later, the marked difference in job control (high vs low) may constitute the difference. Alternatively, age-related effects or adaptive coping mechanisms may have prevented a similar second blood pressure rise despite exposure to a job strain of similar severity. However, there was also a high 19-year total mortality in the study population, which could be related to long-term health consequences of the first or both economic crises. This study provides some support for the notion that increased job strain elevates blood pressure and deteriorates outcome.

Abstract
BACKGROUND The cause of death in cases of sudden and unexpected death is determined by the forensic pathologist based on autopsy findings and toxicological analysis. In cases where no acute pathology or lethal injury are detected, and the circumstances surrounding the death were highly stressful or emotional, it is possible to attribute the inciting event as contributory to the death by causing cardiac dysrhythmia. METHOD Ten cases of sudden death related to stressful events were examined over a period of 2 years in the National Center of Forensic Pathology, all of which lacked findings of acute disease or serious injury. All suffered from variable degrees of chronic cardiac pathology, which probably contributed to dysrhythmia and death. DISCUSSION Since the seventies of the previous century, forensic pathologists are entitled to determine mode of death as homicide or manslaughter, due to an acute cardiac event which cannot be diagnosed in an autopsy and which was a direct result of the circumstances prior to death. Later, these conditions were adjusted to include cases where no morphological findings were detected or when death is delayed by medical treatment. The physiological mechanisms responsible include an increase in catecholamine levels, an increase in blood pressure and platelet aggregation and a delay in cardiac and vascular recovery from stress. CONCLUSIONS Victims of sudden death caused by emotional stress, during a criminal act, usually have a background of chronic cardiac disease and/or are more susceptible physiologically to suffer an amplified reaction to stress. Legally, their deaths are considered as homicide or manslaughter.

Abstract
The authors assessed the effect of psychological stress on total and cause-specific mortality among men and women. In 1981-1983, the 12,128 Danish participants in the Copenhagen City Heart Study were asked two questions on stress intensity and frequency and were followed in a nationwide registry until 2004, with <0.1% loss to follow-up. Sex differences were found in the relations between stress and mortality (p = 0.02). After adjustments, men with high stress versus low stress had higher all-cause mortality (hazard ratio (HR) = 1.32, 95% confidence interval (CI): 1.15, 1.52). This finding was most pronounced for deaths due to respiratory diseases (high vs. low stress: HR = 1.79, 95% CI: 1.10, 2.91), external causes (HR = 3.07, 95% CI: 1.65, 5.71), and suicide (HR = 5.91, 95% CI: 2.47, 14.16). High stress was related to a 2.59 (95% CI: 1.20, 5.61) higher risk of ischemic heart disease mortality for younger, but not older, men. In general, the effects of stress were most pronounced among younger and healthier men. No associations were found between stress and mortality among women, except among younger women with high stress, who experienced lower cancer mortality (HR = 0.51, 95% CI: 0.28, 0.92). Future preventive strategies may be targeted toward stress as a risk factor for premature death among middle-aged, presumably healthy men.

Abstract
We investigate the association between psychological stress and breast cancer and, as oestrogen may provide a common mechanism, the association between stress and prostate cancer. A prospective study of 991 women and 5743 men employed in Scotland in the 1970s provided data. Risk exposure was measured by questionnaire and physical examination, routine data collection provided cancer outcomes over the subsequent 30 years. There was weak evidence of elevated incidences in those reporting moderate (breast cancer: hazard ratio [HR] 2.16, 95% CI 1.00-4.71; prostate cancer: HR 1.65, 95% CI 1.20-2.27) and high stress (breast cancer: HR 1.92, 95% CI 0.81-4.55; prostate cancer: HR 1.35, 95% CI 0.87-2.10) compared to those reporting low stress. These estimates are adjusted for socioeconomic circumstances and health-related behaviours. With no dose-response relationship and no established mechanism linking stress with breast and prostate cancer, confounding is the parsimonious explanation of these findings.

Abstract
BACKGROUND Clinical management of families with autosomal recessive genetic disorders focuses almost exclusively on the affected family members. However, clinically unaffected members of such families may also be severely troubled by the serious illness in a family member. The purpose of this study was to explore the experiences of healthy siblings of patients with a chronic genetic disease, Fanconi Anemia (FA). PROCEDURE We used a qualitative, descriptive design, which consisted of in-depth, semi-structured interviews. A convenience sample of nine siblings of patients with FA was recruited from a National Cancer Institute clinical research protocol, which targets families with inherited bone marrow failure syndromes. NVivo 2.0 software facilitated qualitative content analysis of the data. RESULTS Siblings' rich descriptions provided novel insights into the intricate hardships of living within a family in which a rare, life-threatening, chronic genetic illness in one member is the focus of daily life. Four major themes of the sibling experience emerged from the interview data: (1) containment, (2) invisibility, (3) worry, and (4) despair. CONCLUSIONS Our data suggest that unrecognized psychosocial issues exist for the apparently healthy siblings of patients with FA. This study explores the psychosocial consequences of living in a family with FA and one of only a few studies to explore the sibling experience of chronic illness using a contemporaneous approach. These findings support the need for an increased awareness among health care providers; future hypothesis driven investigation, and improved assessment of problems with potential psychological morbidity.

Abstract
Psychological factors may have an influence on disease processes and therefore they were investigated in the Japan Collaborative Cohort Study. Overall there were very few consistent associations with cancer death. Persons with 'ikigai', defined as 'that which most makes one's life seem worth living', demonstrated decreased risk of mortality from all causes, ischemic heart disease (IHD) and cerebrovascular disease (CVD).There was no consistent link with being quick to judge, although those answering no to quick judgement were at increased risk of all cause, IHD and CVD mortality. psychological stress was related to a slightly elevated risk of all cause death, IHD in men and CVD in women. However, a sense of hurry was linked to a slightly reduced risk for mortality from all causes and CVD. Persons who were likely to be angry had an increased risk for mortality from all causes. In women not likely to be angry there were also positive links to death from cancers like breast. Joyfulness was associated with decreased mortality, especially from CVD. A feeling of being trusted was also protective, again particularly for CVD.

Abstract
Sedation in the context of palliative medicine is the monitored use of medications to induce varying degrees of unconsciousness to bring about a state of decreased or absent awareness (i.e. unconsciousness) in order to relieve the burden of otherwise intractable suffering. Sedation is used in palliative care in several settings: transient controlled sedation, sedation in the management of refractory symptoms at the end of life, emergency sedation, respite sedation, and sedation for refractory psychological or existential suffering. Sedation is controversial in that it diminishes the capacity of the patient to interact, function, and, in some cases, live. There is no distinct ethical problem in the use of sedation to relieve otherwise intolerable suffering in patients who are dying. Since all medical treatments involve risks and benefits, each potential option must be evaluated for its promise with regards to achieving the goals of care. When risks of treatment are involved, to be justified these risks must be proportionate to the gravity of the clinical indication. Some aspects of management, such as the need for hydration in patients undergoing sedation and the use of sedation in the management of psychological and spiritual suffering, remain controversial.

Abstract
Does psychological distress increase mortality risk? If it does, are women more vulnerable than men to the effect of distress on mortality? Drawing from cumulative disadvantage theory, these questions are addressed with data from a 20-year follow-up of a national sample of adults ages 25-74. Event history analyses were performed to examine mortality from general and specific causes for men and women. Findings reveal that the effect of psychological distress on all-cause mortality was nonlinear for men. Moderate amounts of distress were associated with lower mortality risk, but high levels of distress raised men's mortality risk. Moreover the curvilinear relationship between distress and mortality varied by cause of death for men and women. Men with high levels of psychological distress were more vulnerable to ischemic heart disease mortality. Women with high levels of distress were more vulnerable to cancer mortality.

Abstract
This study employed a 22-state mortality follow-back survey to examine bereaved family members' perception of the level and pattern of distressing pain in decedents with cancer at the last two sites of care. Of the 1,578 individuals interviewed, 423 of their family members had cancer listed as the leading cause of death on the decedent's death certificate. Decedents were treated at home, hospitals, hospices, or nursing homes, with more than half of the respondents (n = 216) reporting that the decedent was at more than one site of care in the last month. Forty-two percent of decedents had distressing pain (defined as "quite a bit" or "very much") at their second to last place of care, with 40% having distressing pain at the last place. There was some variation in the degree of change depending on the transition between the second to last and last places of care. For many individuals, however, the transition to another place of care did not result in an improvement in the level of distressing pain. No significant differences were found in the change in distressing pain by transition of care. Increased attention is needed not only on how to adequately manage pain and pain-related distress but also on how to improve pain reduction measures in transitions between health care settings at the end of life.

Abstract
OBJECTIVE A chronic lack of recovery from work during leisure time is hypothesized to indicate a health risk among employees. We examined whether incomplete recovery from work predicted cardiovascular mortality. METHODS This prospective cohort study involved 788 industrial employees (534 men, 254 women, mean age 37.3, SD = 12.0) who were initially free from cardiovascular diseases. The baseline examination in 1973 determined cases of cardiovascular disease, cardiovascular risk factors, and the extent of recovery from work. Data on mortality in 1973 to 2000 were derived from the national mortality register. RESULTS Sixty-seven cardiovascular deaths and 102 deaths from noncardiovascular causes occurred during the mean follow-up of 25.6 years. Employees who seldom recovered from work during free weekends had an elevated risk of cardiovascular death (p = .007) but not of other mortality (p = .82). The association between incomplete recovery and cardiovascular death remained after adjustment for age, sex, and 16 conventional risk factors, including occupational background, cholesterol, systolic pressure, body mass index, smoking, alcohol consumption, physical inactivity, depressive symptoms, fatigue, lack of energy, and job stress. The association was not explained by deaths that occurred close to the assessment of recovery from work. CONCLUSIONS This study suggests that incomplete recovery from work is an aspect of the overall risk profile of cardiovascular disease mortality among employees.

Abstract
STUDY OBJECTIVE To find out if people perceiving nervousness, uneasiness, and anxiety have excess risks of premature death and severe morbidity. DESIGN, SETTING, PARTICIPANTS Random samples of the Swedish population aged 16-74 years in 1980-81, 1988-89, and 1995-96 were followed up for 5 and 10 years with regard to deaths and hospital admissions for different causes. Relative risks were estimated by Poisson regression, comparing those who reported perceived nervousness, uneasiness, and anxiety with those who did not and adjustments were made for baseline characteristics as age, education, smoking, and longstanding illness. MAIN RESULTS Perceived nervousness, uneasiness, and anxiety was strongly related to subsequent risks of suicide attempt and psychiatric disease. Those perceiving severe complaints of anxiety had a relative risk (fully adjusted) for suicide attempt of 9.2 (95% CI 3.0 to 28.8) for men and 3.1 (1.4 to 7.1) for women. Even for less severe complaints, there was a significant, but less pronounced excess risk. These negative feelings were also associated with later risks for all cause mortality, hospital care, and ischaemic heart disease, although to a lesser extent and more strongly among men. Unchanged relative risks over time shows no trend in response attitude and perceived anxiety seems to be a better predictor of a negative health outcome than self reported longstanding illness. CONCLUSIONS Positive responses to self report survey questions about anxiety/nervousness are associated with adverse health outcomes, particularly hospital admission for deliberate self harm. This is an alarming signal bearing in mind the rapid increase in prevalence of perceived anxiety in the Swedish society.
