Abstract
Higher prevalence of depression in females might be associated with sex-specific cortisol levels. Evidence exists that cortisol levels differ between healthy females and males, however a sex-specific association in depression has not been systematically assessed. Thus, the current study quantifies the existing literature on different cortisol parameters, i.e., basal cortisol, hair cortisol, cortisol awakening response (CAR), and cortisol stress reactivity comparing depressed females and males as well as sex-specific comparisons with healthy controls. Following an extensive literature research, fifty original articles were included. Depressed females had significantly higher hair cortisol, higher CAR, and lower cortisol stress reactivity compared to depressed males. In comparison with sex-matched controls, female patients had significantly higher evening basal cortisol, higher CAR and lower cortisol stress reactivity, and male patients had significantly higher general, morning and evening basal cortisol. Overall, sex as a fundamental driver of cortisol levels in depression needs to be taken into account.

Child Adolesc Psychiatry Ment Health 2023; 17:23. [PMID: 36755284 PMCID: PMC9909953 DOI: 10.1186/s13034-023-00568-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 01/11/2023] [Indexed: 02/10/2023] Open
Abstract
BACKGROUND Bereavement is a common traumatic event associated with adverse health outcomes across the life course. Despite these risks, not all bereaved individuals experience these negative effects. Limited scientific consensus exists on how to define resilience in individuals who have experienced the death of a loved one. METHODS Using a sample of N = 3766 youth from the Avon Longitudinal Study of Parents and Children birth cohort, we identified bereavement of a family member between ages 7 and 8.5. We derived and compared three different approaches to assess resilience among bereaved youth. Trajectory-based psychological resilience identified sub-groups with similar psychological symptom profiles between ages 6 and 16 using latent growth mixture models. Relative psychological resilience at age 16 leveraged standardized residuals from a model regressing psychological symptoms on bereavement to determine better-than-expected psychological functioning relative to bereavement status. Relative cross-domain resilience around age 16 was a sum score of the residuals approach applied to eight unique domains of health. Predictive validity of each approach was assessed using depressive symptoms at age 17.5 RESULTS: Overall, N = 877 (23%) youth were bereaved of a family member between ages 7 and 8.5. Using latent growth mixture models, a three-class solution described 84% of bereaved youth with low and stable psychological symptoms over time, 8% with worsening symptoms, and 8% with improving yet elevated symptoms. Each relative resilience score was largely concordant with the trajectory-based approach in identifying individuals as resilient or not, though relative psychological resilience demonstrated a stronger degree of concordance than the cross-domain score. Relative psychological and cross-domain resilience exhibited moderate to low correlation, depending on the domains included (r = 0.14-0.43). For each approach, resilience significantly predicted lower depressive symptoms at age 17.5, highlighting predictive validity of these measures. CONCLUSIONS Psychological symptom trajectories among bereaved youth aligned with those previously identified among bereaved adults. The residual-based approach to defining resilience exhibited limited utility in the context of bereavement. When identifying risk and resilience after bereavement, researchers and clinicians must address the interplay across psychosocial and physical health domains, as bereaved youth considered resilient from a mental health perspective may benefit from intervention in other domains.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12108.

Abstract
Many emerging adults experience the death of a loved one while they are enrolled as a student in higher education. Bereavement increases the risk of long-term adverse physical and mental health outcomes. Still, as most studies have focused on psychological aspects of grief, little is known about the impact of grief on somatic complaints in students, leaving them vulnerable to health deteriorations. This study aimed to address this gap, and we hypothesized that there is a positive association between grief and somatic complaints in bereaved students. Participants (N = 688) were students enrolled at Flemish universities and colleges in Belgium. Participants filled out an online survey with sociodemographic questions, two scales assessing grief, and somatic grief reactions, and two additional questions inquiring whether participants had experienced other somatic reactions, and whether they had taken any steps to remedy their somatic complaints. Regression analyses revealed that less social support, type of relationship (first-degree relative), and the level of grief were positively associated with somatic complaints, and bereaved students reported various complaints such as feeling pain and strains, thus confirming the hypothesis. As bereaved students may be reluctant to seek support for somatic complaints, the findings indicate that information and psychoeducation for bereaved students and their social environment must address somatic grief reactions and encourage timely help seeking. In addition, staff members at psychosocial and medical services for students should be trained to recognize somatic as well as psychological grief reactions. Appropriately skilled, they can inquire about such complaints and provide adequate support to prevent long-term health ramifications.

Abstract
Background: Experiences of negative social interactions and childhood trauma (CT) can lead to aberrant hypothalamic-pituitary-adrenal functions. Poor theory of mind (ToM) ability is related to increased social stress levels; however, studies on the relationship between ToM and cortisol remain scarce. Objective: This study aimed to evaluate the relationship between ToM and the hair cortisol concentration (HCC) in healthy young adults considering the moderating role of CT. Method: A total of 206 healthy young adults were divided into two groups based on an experience of moderate-to-severe childhood trauma (CT+ and CT-). To determine whether CT moderated the relationship between ToM and HCC, moderation analysis was conducted controlling for age, sex, years of education, and scores of perceived stress, depression, and anxiety. Results: CT+ individuals reported higher subjective stress perception and depressive symptoms than CT- individuals, whereas anxiety-related symptoms, ToM, and HCC were not different between the groups. The experience of CT significantly moderated the relationship between ToM and HCC. The association between poorer ToM ability and higher HCC was significant only in CT+ group. Conclusion: CT is a moderator of the association between ToM and HCC, indicating the importance of CT in social cognition and the stress response.

Abstract
Nonhuman primates are frequently transported to a new location or temporarily relocated within their colony. Both transportation and relocation expose animals to new environments, causing them to undergo a stress response (before adapting). In our NHP colony, the mentioned situations are not infrequent for many reasons, including maintenance. The objective of this study was to determine whether abrupt changes consisting of relocation, housing, separation, and grouping could influence hematological and immunological parameters and thereby functional activity. The current study used squirrel monkeys as a model to investigate the stress-inducing effects of relocation within a facility, while animals acclimated to new situations (physical, housing). A detailed blood analysis revealed significant changes in lymphocytes, triglycerides, total protein, creatinine, and ALT. Flow cytometric analysis of peripheral blood showed reduction in CD3+, CD4+, and CD8+ T cells and monocytes, while B cells and natural killer (NK) cells changed with relocation. Simultaneously, changes in functional activity of immune cells altered proliferative responses and as shown by ELISpot (IFN γ). Though the parameters studied are not affected as severely as those in animals transported by road or air, stress responses induced by intrafacility relocation are significant and worth consideration. Our findings indicate that squirrel monkeys mimic the features seen in humans exposed to social stressors and may serve an important model for understanding the mechanisms of stress-induced immune dysfunction in humans.

Abstract
OBJECTIVE The death of a parent during childhood is a severe life event with potentially long-term consequences. Earlier studies have shown an increased risk of cardiovascular diseases (CVD) after the death of a spouse, child, or sibling. Whether parental death during childhood is associated with an increased risk of incident CVD is unknown and was investigated in this study. METHODS We studied 48,992 men born 1949 to 1951 and enlisted for military conscription in 1969 to 1970. We obtained information on death of a parent during childhood, CVD up to 2008, and covariates by linking the questionnaire and the clinical examination data from conscription with nationwide socioeconomic and health registers. RESULTS Men who lost a parent during childhood had an increased risk of ischemic heart disease (IHD; adjusted hazard ratio (HR) and 95% confidence interval [CI] = 1.30 [1.13-1.49]) but not of stroke during the 39-year follow-up (adjusted HR [95% CI] = 0.87 [0.66-1.15]). Maternal death was associated with IHD both when the loss was due to cardiovascular (adjusted HR [95% CI] = 2.04 [1.02-4.08]) and unnatural causes (adjusted HR [95% CI] = 2.50 [1.42-4.42]); in case of paternal death, an increased IHD risk was observed only when the loss was due to cardiovascular causes (adjusted HR [95% CI] = 1.82 [1.37-2.42]). There were no substantial differences in CVD according to the child's age at the loss. CONCLUSIONS Parental death during childhood was associated with an increased risk of IHD in men. If these associations are confirmed in future studies, the long-term effects of childhood bereavement may warrant attention.

Abstract
Although there is an abundance of evidence linking the function of the hypothalamic-pituitary-adrenal (HPA) axis to adverse early-life experiences, the precise nature of the association remains unclear. Some evidence suggests early-life adversity leads to cortisol hyper-reactivity, while other evidence suggests adversity leads to cortisol hypo-reactivity. Here, we distinguish between trauma and adversity, and use p-curves to interrogate the conflicting literature. In Study 1, trauma was operationalized according to DSM-5 criteria; the p-curve analysis included 68 articles and revealed that the literature reporting associations between trauma and blunted cortisol reactivity contains evidential value. Study 2 examined the relationship between adversity and cortisol reactivity. Thirty articles were included in the analysis, and p-curve demonstrated that adversity is related to heightened cortisol reactivity. These results support an inverted U-shaped function relating severity of adversity and cortisol reactivity, and underscore the importance of distinguishing between "trauma" and "adversity".

Abstract
African-American women have elevated rates of cardiovascular disease compared with women of other races or ethnicities, and race/ethnicity-related stressors may play a role. We examined the association between a race/ethnicity-related stressor, midlife loss, and a marker of cardiovascular risk, carotid intima media thickness (IMT), in 1,410 African-American, White, Chinese, and Hispanic women from the Study of Women's Health Across the Nation. Participants were queried about losses annually over 12 years (1996-2013), with IMT assessed in year 12-13 via ultrasound. Linear regression models were used to examine associations between cumulative upsetting losses and IMT, adjusting for covariates. In minimally adjusted models in the full cohort, 3 or more upsetting losses (vs. none) were associated with IMT (β = 0.03, 95% confidence interval (CI): 0.01, 0.05; P = 0.0003). Results were more robust among African-American women (β = 0.042, 95% CI: 0.01, 0.07; P < 0.01) than White (β = 0.014, 95% CI: -0.01, 0.03; P = 0.21), Chinese (β = 0.036, 95% CI: -0.03, 0.10; P = 0.25), or Hispanic (β = 0.036, 95% CI: -0.07, 0.14; P = 0.51) women, although associations among women from racial/ethnic minorities overall were of similar magnitude. Results persisted in fully adjusted models (P for interaction with race/ethnicity = 0.04). Midlife loss may be a pathway through which race/ethnicity influences cardiovascular risk for African-American women and, potentially, Chinese and Hispanic women.

Abstract
PURPOSE Chronic stress is associated with increased risk for maladaptive psychological responses during childhood, adolescence, and young adulthood. Adults exposed to chronic stress during childhood exhibit dysregulation of hypothalamic-pituitary-adrenal (HPA) axis activity and inflammation. There are no studies examining the impact of stress on biological stress responses and functional impairment in adolescents and young adults early after the onset of a stressor. METHODS The sample consisted of 59 offspring, aged 11-25 years, 33 of parents diagnosed with cancer and 26 controls from families with no cancer or severe chronic illness in parents or siblings. Cancer patients and their families were recruited within an average of 62 days (SD = 35.9) and followed at 6 and 9 months later. Functional impairment was assessed and hair cortisol concentrations (HCC), salivary cortisol, and inflammatory markers were measured. Mixed regression analyses were conducted. RESULTS The stress group showed higher functional impairment (β = -5.5, 95% CI (-10.4, -0.06), p = 0.03, d= -0.40) and HCC (β = 10.5, 95% CI (-5.5, -0.50), p < 0.001, d = 1.43). However, HCC were reduced over time in the stress group (β= -0.3, 95% CI (-0.04, -0.01), p < 0.001, d = -1.08). Higher total cortisol output was associated with increased functional impairment over time (β = -3.0, 95% CI (-5.5, -0.5), p = 0.02, d = -0.60). CONCLUSIONS Parental cancer is associated with early increase in cortisol, which was associated with increased functional impairment in offspring. Clinicians need to assess and monitor psychiatric symptoms and functioning in these offspring early on following parental cancer diagnosis.

Abstract
Understanding the developmental timing of stress exposure may help inform mechanisms underlying how stress "gets under the skin" and influences the stress response system, including the HPA axis and its end-product cortisol. Early adversity may be particularly detrimental; however, it is difficult to disentangle the timing of adversity from its cumulative burden because there is typically high continuity between early and later adversity. Moreover, context and the different stressors inherent in various contexts may interact with stress exposure to influence psychophysiological functioning. To address this issue, we examined adolescents who had been reared in institutions and suffered neglect or social deprivation ranging from approximately six months to several years of life prior to adoption into U.S. homes. We focused on the stress hormone cortisol because it can reflect continued regulatory problems in youth, even years after youth transition to typical homes. We examined cortisol morning levels and diurnal rhythms across multiple contexts (home, school, lab) on 5 separate days in 41 post-institutionalized youth and 78 comparison youth. Employing hierarchical linear modeling, we found that when assessed in the lab, post-institutionalized (PI) youth displayed lower morning cortisol levels and flatter diurnal slopes than the control youth. Yet at home, PI youth displayed higher morning cortisol levels than the control youth. In addition to group effects, we also examined severity of early adversity and found that PI kids who had endured the most severe early adversity displayed lower home cortisol levels than controls. No significant predictors of diurnal cortisol on school days were identified. These data fit with the notion that the HPA axis is impacted by early adversity, even years after adoption, and with emerging theories that postulate that stress physiology calibrates within youth to help them adapt to their context. In the case of severe early adversity, the cost of such adaptation may not be desirable. It also highlights the important role of context when assessing HPA axis activity, particularly in post-institutionalized youth.

Abstract
OBJECTIVE To examine the association between cortisol response to stress and suicidal ideation (SI) cross-sectionally and longitudinally in our sample of bereaved and non-bereaved youth. METHODS The sample included 114 youth bereaved by sudden parental death and 109 non-bereaved controls, mean age of 12.3 (SD = 3.6), evaluated at four time-points over an average follow-up period of 7 years. The Trier Social Stress Test (TSST) was conducted on average 6 years after bereavement. We used latent class analyses to examine the trajectories of SI over follow-up and up to the time of the TSST and compare them on cortisol measures. We examined whether cortisol measures predicted future SI at 18.5 months on average after the TSST. RESULTS Bereavement was associated with higher cortisol reactivity after controlling for covariates [β = 0.96, 95% CI (0.28, 1.65), p < 0.01, d = 0.41]. Cortisol reactivity to stress was higher in those belonging to the high SI trajectory [β = 1.23, 95% CI (0.41, 2.06), p = 0.004, d = 0.23] compared to the low SI trajectory. Higher baseline cortisol showed small to medium effect size in predicting future SI [β = 2.34, 95% CI (0.17, 4.51), p = 0.03, d = 0.38]. CONCLUSION The persistence of SI is associated with higher cortisol reactivity to stress, and higher baseline cortisol may predict future SI. These results emphasize the importance of HPA-axis activity in youth exposed to major stressors, and those with SI. More research is needed to further clarify biological mechanisms linking SI and behavior, bereavement, and HPA axis response to stress, to better identify at-risk subjects for targeted prevention and intervention efforts.

Abstract
Buddhist Chaplains chanting sutras after the Great East Japan Earthquake in 2011 often encountered survivors who felt that hearing sutra chanting itself ameliorated their bereavement grief. This research is the first experimental examination of the effects of sutra chanting on listeners' bereavement stress. Prior research demonstrates that sudden pet loss causes bereavement stress in students and that physiological stress can be noninvasively measured by salivary alpha-amylase. We asked Japanese college students to raise pet goldfish until they developed an attachment to them, then confiscated the fish, and told the students that they had to be killed. To compare the bereavement stress of groups listening and not listening to sutra chanting, we used psychological and salivary analyses. Perceived Stress Scale (PSS), Multidimensional Empathy Scale (MES), and State half of the State Trait Anxiety Inventory (STAI) psychological scales showed no statistically significant differences between sutra and control groups, but salivary analyses indicated measurable stress reduction in the sutra-listening group only. This pilot study tentatively confirmed the hypothesis that listening to Buddhist sutra chanting reduces Japanese bereavement stress. Further research is needed both to verify these stress-reduction effects and to determine whether such effects are primarily musical or cultural/spiritual.

Abstract
This article aims to make reference to some recent mourning aspects considered risk factors for cardiovascular disease, specifically the Takotsubo cardiomyopathy. The objective was to describe the stress from the death of a loved one combining it to the possibility of occurrence of Takotsubo cardiomyopathy through the perception of a traumatic event by the cortex, which triggers the subcortical brain circuit affecting the endocrine response. Given the growing acknowledgement of this cardiomyopathy, it is possible to contextualize the nutritional behaviours and decisions surrounding it, whose benefits must exceed the condition of temporary cardiac dysfunction and extend to food choices that have some influence in the limbic system. It is a descriptive analysis that aims to problematize the theme into reflections based on this experience, considering the foundation with the science of nutrition.

Abstract
OBJECTIVE To examine differences in blood pressure response and recovery in a sample of bereaved and non-bereaved youths during an acute stress task conducted 5 years after time of parental death. METHODS One-hundred and ninety-two (n = 192) bereaved and non-bereaved offspring (ages 11-29) participated in an adaptation of the Trier Social Stress Task (TSST) 5-years after the time of parental death. Blood pressure measurements were collected before, during, and after the laboratory stress protocol. Mixed models for repeated measures were used to analyze the effects of bereavement status and course of psychiatric disorder in the 5-year period after parental death in both offspring and caregivers on blood pressure response; linear regression was used to examine these associations with blood pressure recovery. RESULTS Although there were no differences across groups in diastolic (DBP) or systolic blood pressure (SBP) response to stress, bereaved offspring demonstrated less SBP recovery to the TSST as compared to non-bereaved offspring. A significant interaction between bereavement status and race, and a marginally significant interaction between bereavement status and sex indicated poor SBP recovery for parentally bereaved racial/ethnic minority offspring as compared to parentally bereaved Caucasian offspring, and for parentally bereaved males compared to parentally bereaved females. CONCLUSIONS Parentally bereaved youths demonstrate blood pressure response to social stress tasks similar to that of non-bereaved youths, but parentally bereaved ethnic/racial minority youths and parentally bereaved males evidence a less complete recovery from the effects of stress. The health consequences of poor blood pressure recovery in bereaved youths are discussed.

Abstract
Psychosocial stress during childhood and adolescence is associated with alterations in the hypothalamic-pituitary-adrenal (HPA) axis and with heightened inflammation, both of which are implicated in poor health; however, factors that may protect against these effects relatively early in life are not well understood. Thus, we examined whether psychosocial resources protect against stress-related alterations in the HPA axis and heightened inflammation in a sample of 91 late adolescents. Participants completed measures of various stressors (major life events, daily interpersonal stress, early adversity), and psychosocial resources (mastery, optimism, self-esteem, and positive reappraisal). They also completed the Trier Social Stress Test and provided saliva and blood samples for the assessment of cortisol and interleukin-6 reactivity. Each of the stressors was associated with lower cortisol reactivity. Additionally, associations with major life events and daily stress were moderated by psychological resources, such that more life events and daily stress were associated with decreased HPA reactivity among adolescents with lower levels of psychological resources, but not among those with higher levels of psychological resources. This pattern of findings was observed only for cortisol reactivity and not for interleukin-6 reactivity. Findings suggest that psychological resources may counteract the effects of certain adversity-related decreases in cortisol reactivity.

Abstract
This paper studies how in utero exposure to maternal stress from family ruptures affects later mental health. We find that prenatal exposure to the death of a maternal relative increases take-up of ADHD medications during childhood and anti-anxiety and depression medications in adulthood. Further, family ruptures during pregnancy depress birth outcomes and raise the risk of perinatal complications necessitating hospitalization. Our results suggest large welfare gains from preventing fetal stress from family ruptures and possibly from economically induced stressors such as unemployment. They further suggest that greater stress exposure among the poor may partially explain the intergenerational persistence of poverty.

Abstract
BACKGROUND Hypothalamic-Pituitary-Adrenal (HPA) axis dysregulation is associated with increased risk for suicidal behavior. However, it is not clear whether such dysregulation exists prior to or is a consequence of attempt. Studies also show an activation of inflammatory responses in suicidal behavior but often combine attempters with those with ideation. METHODS The sample consisted of psychiatric inpatients, aged 15-30 years, admitted for suicide attempt (SA, n=38), inpatients admitted for suicidal ideation with no prior history of attempts (SI, n=40), and healthy controls (n=37). We compared SA, SI, and controls on hair cortisol concentrations (HCC), which provides retrospective levels of cortisol and thus prior to the attempt in SA. We also compared them on the expression of genes in the HPA axis and inflammatory pathways previously implicated in suicidal behavior (GR or NR3C1, SKA2, FKBP5, IL-1β, TNF-α); plasma C-Reactive Protein (CRP); and cellular measures of glucocorticoid receptor (GR) sensitivity and stimulated production of IL-6. RESULTS We found lower HCC [β=-0.55, 95% CI (-0.96, -0.13), p=0.01, ES=-0.54] in first-time SA compared to SI and controls. In addition, SA showed lower GR or NR3C1 (α isoform) mRNA [β=-5.11, 95% CI (-10.9, 0.73), p=0.09, ES=-0.46], higher CRP [β=0.94, 95% CI (-0.004, 1.9), p=0.05, ES=0.60], and higher TNF-α mRNA [β=26.4, 95% CI (7.7, 45.2), p=0.006, ES=0.73]. CONCLUSIONS This is the first study to differentiate youth who attempt suicide from those with suicidal ideation on HCC and to show that low HCC precedes suicide attempt. Suicide attempters also showed a distinct biological profile on several markers in both the HPA axis and inflammatory pathways. Future longitudinal studies are needed to examine the ability of these biomarkers to predict suicidal behavior.

Abstract
The hypothalamus-pituitary-adrenal (HPA) axis and its end product cortisol are essential for an adequate response to stress. Considering the role of stress as a risk factor for psychiatric disorders, it is not surprising that cortisol stress reactivity has frequently been investigated in patients versus healthy individuals. However, the large heterogeneity in measures of the cortisol stress response has hampered a systematic evaluation of the evidence. We here report of a systematic literature review and meta-analysis on cortisol reactivity to psychosocial stress across psychiatric disorders. Original data from authors were obtained to construct standardized cortisol outcomes (the areas under the curve with respect to increase (AUCi) and ground (AUCg)) and to examine the influence of sex and symptomatic state on cortisol stress reactivity. Fourteen studies on major depressive disorder (MDD) (n=1129), 9 on anxiety disorders (n=732, including social anxiety disorder (SAD), posttraumatic stress disorder, panic disorder and mixed samples of anxiety disorders) and 4 on schizophrenia (n=180) were included that used the Trier Social Stress Test or an equivalent psychosocial stress task. Sex-dependent changes in stress reactivity were apparent in MDD and anxiety disorders. Specifically, women with current MDD or an anxiety disorder exhibited a blunted cortisol stress response, whereas men with current MDD or SAD showed an increased cortisol response to psychosocial stress. In individuals with remitted MDD, altered cortisol stress reactivity was less pronounced in women and absent in men. For schizophrenia, cortisol stress reactivity was blunted in both men and women, but the number of studies was limited and showed evidence for publication bias. These findings illustrate that sharing individual data to disentangle the effects of sex, symptom levels and other factors is essential for further understanding of the alterations in cortisol stress reactivity across psychiatric disorders.

Abstract
Cross-sectional research suggests that individuals at risk for internalizing disorders show differential activation levels and/or dynamics of stress-sensitive physiological systems, possibly reflecting a process of stress sensitization. However, there is little longitudinal research to clarify how the development of these systems over time relates to activation during acute stress, and how aspects of such activation map onto internalizing symptoms. We investigated children's (n = 107) diurnal hypothalamic-pituitary-adrenal activity via salivary cortisol (morning and evening levels) across 29 assessments spanning 6+ years, and related longitudinal patterns to acute stress responses at the end of this period (age 9-10). Associations with child psychiatric symptoms at age 10 were also examined to determine internalizing risk profiles. Increasing morning cortisol levels across assessments predicted less of a cortisol decline following interpersonal stress at age 9, and higher cortisol levels during performance stress at age 10. These same profiles of high and/or sustained cortisol elevation during psychosocial stress were associated with child anxiety symptoms. Results suggest developmental sensitization to stress-reflected in rising morning cortisol and eventual hyperactivation during acute stress exposure-may distinguish children at risk for internalizing disorders.

Abstract
OBJECTIVES Suicidal behaviour (SB) entered the DSM-5, underlying a specific biological vulnerability. Then, recent findings suggested a possible role of the immune system in SB pathogenesis. The objective of this review is to present these main immune factors involved in SB pathogenesis. METHODS We conducted a review using Preferred Reporting Items for Systematic reviews and Meta-Analysis criteria, and combined ("Inflammation") AND ("Suicidal ideation" OR "Suicidal attempt" OR "suicide"). RESULTS Post mortem studies demonstrated associations between suicide and inflammatory cytokines in the orbitofrontal cortex, a brain region involved in suicidal vulnerability. Also, microgliosis and monocyte-macrophage system activation may be a useful marker of suicide neurobiology. Kynurenine may influence inflammatory processes, and related molecular pathways may be involved in SB pathophysiology. Few recent studies associated inflammatory markers with suicidal vulnerability: serotonin dysfunction, impulsivity and childhood trauma. Interestingly, the perception of threat that leads suicidal individuals to contemplate suicide may activate biological stress responses, including inflammatory responses. CONCLUSIONS Translational projects would be crucial to identify a specific marker in SB disorders, to investigate its clinical correlations, and the interaction between inflammatory cytokines and monoamine systems in SB. These researches might lead to new biomarkers and novel directions for therapeutic strategies.

Abstract
Identification of biological indicators of suicide risk is important given advantages of biomarker-based models. Decreased high frequency heart rate variability (HF HRV) may be a biomarker of suicide risk. The aim of this research was to determine whether HF HRV differs between suicide attempters and non-attempters. Using the Trier Social Stress Test (TSST), we compared HF HRV between females with and without a history of suicide attempt, all with a lifetime diagnosis of a mood disorder. To investigate a potential mechanism explaining association between HF HRV and suicide, we examined the association between self-reported anger and HF HRV. Results of an Area under the Curve (AUC) analysis showed attempters had a lower cumulative HF HRV during the TSST than non-attempters. In addition, while there was no difference in self-reported anger at baseline, the increase in anger was greater in attempters, and negatively associated with HF HRV. Results suggest that suicide attempters have a reduced capacity to regulate their response to stress, and that reduced capacity to regulate anger may be a mechanism through which decreased HF HRV can lead to an increase in suicide risk. Our results have implications for the prevention of suicidal behavior in at-risk populations.

Abstract
Studies looking at the relationship of the hypothalamic-pituitary-adrenal (HPA) axis to suicidal behavior and its risk factors, such as depression, childhood abuse, and impulsive aggression, report inconsistent results. These studies also do not always differentiate between subjects who go on to attempt suicide, suicidal subjects who never attempted suicide, and non-suicidal subjects with psychiatric disorders. In this study, we examined cortisol responses to an experimental stressor, the Trier Social Stress Test (TSST), in 208 offspring of parents with mood disorder. Offspring suicide attempters showed lower total cortisol output (β=-0.47, 95% CI (-0.83, -0.11), p=0.01) compared with offspring with suicide-related behavior (SRB) but never attempted, non-suicidal offspring, and a healthy control group. The result remained significant even after controlling for sex, age, race, ethnicity, site, socio-economic status, and hour of the day when the TSST was conducted. Suicide attempters also showed lower baseline cortisol before the TSST (β=-0.45, 95% CI (-0.74, -0.17), p=0.002). However, there were no significant differences between the groups on cortisol reactivity to stress (β=4.5, 95% CI (-12.9, 22), p=0.61). Although subjects with suicide attempt and SRB have similar clinical and psychosocial characteristics, this is the first study to differentiate them biologically on HPA axis indices. Blunted HPA axis activity may increase risk for suicide attempt among individuals with psychopathology by reducing their ability to respond adaptively to ongoing stressors. These results may help better identify subjects at high risk for suicidal behavior for targeted prevention and intervention efforts.

Abstract
BACKGROUND Many, but not all studies of suicide attempters' cortisol response to stress-either social stress or pharmacological challenge-report an exaggerated response. Recent studies of resting baseline cortisol in past suicide attempters, however, have found lower baseline levels. METHODS In this study, baseline salivary cortisols were obtained prior to a stress procedure from adults with lifetime diagnoses of a mood disorder (N=69), 31.9% of whom had made a prior suicide attempt. Data were collected during the piloting of this stress procedure, at various times of day and with/without an additional confederate in the room. RESULTS Adjusting for procedural, demographic and clinical variables that affect salivary cortisol levels-including time of day of sampling, order of procedure with respect to other assessments, past alcohol abuse, current medication use, and bipolar diagnosis-past suicide attempters had lower baseline cortisol levels compared to non-attempters. LIMITATIONS This is a pilot study with modest sample sizes using statistical, rather than experimental control of numerous variables affecting salivary cortisol levels. CONCLUSIONS Results confirm previous studies. Low baseline cortisol levels have been associated with childhood adversity and externalizing disorders, suggesting a potential role in reducing inhibitions for risky and dangerous behaviors. Further research is needed to more fully characterize these associations and their role in suicidal behavior risk.

Abstract
Despite increasing clinical and research interest in suicide bereavement the impact of suicide on adolescents is still poorly understood. This systematic review aims to disentangle pre- and postloss features that affect response to grief in this age group. The literature was analyzed after a systematic search and hand-check of retrieved articles. The impact of suicide is affected by (a) preloss features related to personal/family history of mental health, family life, suicidal behavior, and type and emotional closeness of relationship; and (b) postloss issues such as quality of remaining relationships. Future research and bereavement support should consider these broader contexts.

Perceived stress and musculoskeletal pain are prevalent and significantly associated in adolescents: an epidemiological cross-sectional study. BMC Public Health 2015; 15:1081. [PMID: 26498498 PMCID: PMC4619092 DOI: 10.1186/s12889-015-2414-x] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Accepted: 10/12/2015] [Indexed: 02/08/2023] Open
Abstract
Background Long-term musculoskeletal pain and negative stress are health risks with adverse long-term health effects, and these health risks seem to increase among young people. The mechanisms behind this are unclear. There is a need for a better understanding of perceived stress and musculoskeletal pain among adolescents, in order to improve health promotion and treatment approaches in this group. Methods Objectives were to evaluate the current prevalence of perceived stress and musculoskeletal pain in 15 and 16 year olds, to explore stress-pain associations and the probability that perceived stress (PSQ) was related to the reporting of pain and variations in pain, and to investigate possible differences in stress between different types of musculoskeletal pain in the adolescents. A cross-sectional study was conducted. Elementary schools participated. The outcomes were stress (Perceived stress questionnaire; PSQ) and musculoskeletal pain (pain/no pain, pain sites, pain duration and pain intensity (Visual analogue scale; VAS). Results Fifty-one point two percent (N = 422) reported pain, of which 70.8 % reported long-term pain. Some more girls (57.9 %) reported pain. 22.0 % of the study population reported moderate to severe stress (PSQ ≥ 0.45), of which 79.6 % were bothered by pain (Pearson Chi-square 38.47, p ≤ .001). All stress and pain variables were significantly associated (p < .01). The strongest association appeared between pain intensity (VAS) and stress (PSQ) (r = 0.40). Perceived stress (PSQ) was associated with the reporting of pain among the adolescents (Odds Ratio [OR] 1.68) and could explain some of the variation in pain intensity (VAS; β = 0.15, p < .001) and number of pain sites (β = 0.14, p < .01), according to the regression analyses. There were no mean differences in stress (PSQ) between different types of musculoskeletal pain. Conclusions There was high prevalence of musculoskeletal pain, long-term pain and moderate to severe stress (PSQ ≥ 0.45) in this study sample. Perceived stress (PSQ) was related to the reporting of musculoskeletal pain among the adolescents and could explain some of the variation in pain intensity (VAS) and number of pain sites. There were no differences in stress levels (PSQ) between different types of musculoskeletal pain in the adolescents.

Abstract
Aim: Provision of end-of-life care requires that we have adequate information about the preferred place of death in the population. Since no such study is reported in India, this study was taken up in and around Pune, a large cosmopolitan city. Setting and Design: A questionnaire was designed in three parts and distributed among the people above the age of 18 in and around Pune. Materials and Methods: The questionnaire had three parts the first being a consent form, followed by one for collection of personal information and lastly questions specific to the subject matter. Filled forms were screened for inconsistencies, gaps of information and errors. Results: The population survey was mixed, both urban and rural, men and women, educated and uneducated, young and old. Despite this heterogeneity, the results were consistent to the point that most of the people surveyed preferred home as the place of death. This preference cuts across all barriers, the only difference being that women had a stronger preference for home death compared to men. Conclusions: Helping people to die at their preferred place is a part of end-of-life care. Majority of people surveyed by us, prefer to die at home, where they are relatively more comfortable. Public and governmental policies should be directed toward facilitating home deaths.

Mortality after parental death in childhood: a nationwide cohort study from three Nordic countries. PLoS Med 2014; 11:e1001679.

Abstract
BACKGROUND Bereavement by spousal death and child death in adulthood has been shown to lead to an increased risk of mortality. Maternal death in infancy or parental death in early childhood may have an impact on mortality but evidence has been limited to short-term or selected causes of death. Little is known about long-term or cause-specific mortality after parental death in childhood. METHODS AND FINDINGS This cohort study included all persons born in Denmark from 1968 to 2008 (n = 2,789,807) and in Sweden from 1973 to 2006 (n = 3,380,301), and a random sample of 89.3% of all born in Finland from 1987 to 2007 (n = 1,131,905). A total of 189,094 persons were included in the exposed cohort when they lost a parent before 18 years old. Log-linear Poisson regression was used to estimate mortality rate ratio (MRR). Parental death was associated with a 50% increased all-cause mortality (MRR = 1.50, 95% CI 1.43-1.58). The risks were increased for most specific cause groups and the highest MRRs were observed when the cause of child death and the cause of parental death were in the same category. Parental unnatural death was associated with a higher mortality risk (MRR = 1.84, 95% CI 1.71-2.00) than parental natural death (MRR = 1.33, 95% CI 1.24-1.41). The magnitude of the associations varied according to type of death and age at bereavement over different follow-up periods. The main limitation of the study is the lack of data on post-bereavement information on the quality of the parent-child relationship, lifestyles, and common physical environment. CONCLUSIONS Parental death in childhood or adolescence is associated with increased all-cause mortality into early adulthood. Since an increased mortality reflects both genetic susceptibility and long-term impacts of parental death on health and social well-being, our findings have implications in clinical responses and public health strategies.

Abstract
The goal of the present study was to investigate developmental differences in the effectiveness of parent support to alleviate hypothalamic-pituitary-adrenal (HPA) axis stress responses of children (ages 9-10, N = 40) and adolescents (ages 15-16, N = 41). We experimentally manipulated the provision of parent support during the speech preparation period before a modified Trier Social Stress Test (TSST) and examined its effect on levels of salivary cortisol secreted in response to this laboratory stressor. Analyses revealed a significant interaction of condition and age group such that social support from the parent (versus a stranger) significantly eliminated the cortisol stress response in children, but had no effect on the response among adolescents.

Abstract
Stressful life events have been linked to the onset of severe psychopathology and endocrine dysfunction in many patients. Moreover, vulnerability to the later development of such disorders can be increased by stress or adversity during development (e.g., childhood neglect, abuse, or trauma). This review discusses the methodological features and results of various models of stress in nonhuman primates in the context of their potential relevance for human psychopathology and endocrine dysfunction, particularly mood disorders and dysregulation of the hypothalamic-pituitary-adrenocortical (HPA) system. Such models have typically examined the effects of stress on the animals' behavior, endocrine function (primarily the HPA and hypothalamic-pituitary-gonadal systems), and, in some cases, immune status. Manipulations such as relocation and/or removal of an animal from its current social group or, alternatively, formation of a new social group can have adverse effects on all of these outcome measures that may be either transient or more persistent depending on the species, sex, and other experimental conditions. Social primates may also experience significant stress associated with their rank in the group's dominance hierarchy. Finally, stress during prenatal development or during the early postnatal period may have long-lasting neurobiological and endocrine effects that manifest in an altered ability to cope behaviorally and physiologically with later challenges. Whereas early exposure to severe stress usually results in deficient coping abilities, certain kinds of milder stressors can promote subsequent resilience in the animal. We conclude that studies of stress in nonhuman primates can model many features of stress exposure in human populations and that such studies can play a valuable role in helping to elucidate the mechanisms underlying the role of stress in human psychopathology and endocrine dysfunction.

Abstract
Many promising findings support the notion that social relationships can dampen hypothalamic-pituitary-adrenocortical (HPA) axis stress responses and protect individuals from maladaptive psychological and physical disease states. Despite the public health relevance of this topic, little is known about developmental changes in the social regulation of the HPA system, with most prior research having focused on early childhood and adulthood. This gap is particularly striking with regards to adolescence, an age period when it seems likely that reliance on parents as sources of stress-buffering decreases, even as the security of friends and relationship partners as stress buffers may not yet be certain. Furthermore, we speculate that early life stress or abnormal social experiences may impact the propensity to draw mental and physical health benefits from social relationships, but more empirical support for these ideas is needed. Last, research linking social support to cumulative life stress has mostly relied on self-report measures of stress, making it difficult to show that social support impacts the type of chronic stress exposure that is associated with increased allostatic load or "wear and tear" on the body and on psychological functioning. Recent advancements in methodology (e.g., assessing hair cortisol levels) as well as composite measures of allostatic load using biomarkers that capture the activity of multiple neuroendocrine, cardiovascular, immune, and metabolic systems will allow us to ask new questions about the extent to which social relationships can impact cumulative life stress and health.
