Abstract
Major depressive disorder (MDD) patients commonly encounter multiple types of functional disabilities, such as social, physical, and role functioning. MDD is related to an accreted risk of brain atrophy, aging-associated brain diseases, and mortality. Based on recently available studies, there are correlations between notable biological brain aging and MDD in adulthood. Despite several clinical and epidemiological studies that associate MDD with aging phenotypes, the underlying mechanisms in the brain remain unknown. The key areas in the study of biological brain aging in MDD are structural brain aging, impairment in functional connectivity, and the impact on cognitive function and age-related disorders. Various measurements have been used to determine the severity of brain aging, such as the brain age gap estimate (BrainAGE) or brain-predicted age difference (BrainPAD). This review summarized the current results of brain imaging data on the similarities between the manifestation of brain structural changes and the age-associated processes in MDD. This review also provided recent evidence of BrainPAD or BrainAGE scores in MDD, brain structural abnormalities, and functional connectivity, which are commonly observed between MDD and age-associated processes. It serves as a basis of current reference for future research on the potential areas of investigation for diagnostic, preventive, and potentially therapeutic purposes for brain aging in MDD.

Abstract
Some individuals are susceptible to the experience of chronic stress and others are more resilient. While many brain regions implicated in learning are dysregulated after stress, little is known about whether and how neural teaching signals during stress differ between susceptible and resilient individuals. Here, we seek to determine if activity in the lateral habenula (LHb), which encodes a negative teaching signal, differs between susceptible and resilient mice during stress to produce different outcomes. After, but not before, chronic social defeat stress (CSDS), the LHb is active when susceptible mice are in the proximity of the aggressor strain. During stress itself, LHb activity is higher in susceptible mice during aggressor proximity, and activation of the LHb during stress biases mice towards susceptibility. This manipulation generates a persistent and widespread increase in the balance of subcortical versus cortical activity in susceptible mice. Taken together, our results indicate that heightened activity in the LHb during stress produces lasting brainwide and behavioral substrates of susceptibility.

The role of the Toll like receptor 4 signaling in sex-specific persistency of depression-like behavior in response to chronic stress. Brain Behav Immun 2024; 115:169-178. [PMID: 37838079 PMCID: PMC11146676 DOI: 10.1016/j.bbi.2023.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 10/03/2023] [Accepted: 10/07/2023] [Indexed: 10/16/2023] Open
Abstract
Chronic stress is a major risk factor for Major Depressive Disorder (MDD), and it has been shown to impact the immune system and cause microglia activation in the medial prefrontal cortex (mPFC) involved in the pathogenesis of depression. The aim of this study is to further investigate cellular and molecular mechanisms underlying persistent depression behavior in sex specific manner, which is observed clinically. Here, we report that both male and female mice exhibited depression-like behavior following exposure to chronic stress. However, only female mice showed persistent depression-like behavior, which was associated with microglia activation in mPFC, characterized by distinctive alterations in the phenotype of microglia. Given these findings, to further investigate the underlying molecular mechanisms associated with persistent depression-like behavior and microglia activation in female mice, we used translating-ribosome affinity purification (TRAP). We find that Toll like receptor 4 (TLR4) signaling is casually related to persistent depression-like behavior in female mice. This is supported by the evidence that the fact that genetic ablation of TLR4 expression in microglia significantly reduced the persistent depression-like behavior to baseline levels in female mice. This study tentatively supports the hypothesis that the TLR4 signaling in microglia may be responsible for the sex differences in persistent depression-like behavior in female.

Chronic oral ketamine prevents anhedonia and alters neuronal activation in the lateral habenula and nucleus accumbens in rats under chronic unpredictable mild stress. Neuropharmacology 2023; 228:109468. [PMID: 36813161 DOI: 10.1016/j.neuropharm.2023.109468] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 02/13/2023] [Accepted: 02/16/2023] [Indexed: 02/22/2023]
Abstract
Acute injections of ketamine lead to rapid but transient antidepressant effects. Chronic oral treatment at low doses, a promising non-invasive alternative, may prolong this therapeutic effect. Here, we examine the antidepressant effects of chronic oral ketamine in rats under chronic unpredictable mild stress (CUMS), and reveal their neuronal correlates. Male Wistar rats were divided into control, ketamine, CUMS, and CUMS-ketamine groups. The CUMS protocol was applied to the latter two groups for 9 weeks, and ketamine (0.013 mg/ml) was provided ad libitum to the ketamine and CUMS-ketamine groups for 5 weeks. The sucrose consumption test, forced swim test, open field test, elevated plus maze, and Morris water maze were respectively used to assess anhedonia, behavioral despair, general locomotor activity, anxiety-like behavior and spatial reference memory. CUMS caused a reduction of sucrose consumption and impaired spatial memory, accompanied by increased neuronal activation in the lateral habenula (LHb) and paraventricular thalamic nucleus (PVT). Oral ketamine prevented behavioral despair and CUMS-induced anhedonia. Reward-triggered c-Fos immunoreactivity was decreased in the LHb and increased in the nucleus accumbens shell (NAcSh) in the CUMS-ketamine group compared to the CUMS group. Ketamine did not produce a differential effect in the OFT, EPM and MWM. These results show that chronic oral ketamine at low doses prevents anhedonia without impairing spatial reference memory. The observed neuronal activation changes in the LHb and NAcSh may be involved in the preventive effects of ketamine on anhedonia. This article is part of the Special Issue on "Ketamine and its Metabolites".

Abstract
This review focuses on research my colleagues and I have conducted on etiological pathways to depression. Much of this work has focused on the measurement of neural responses to appetitive cues, using two event-related brain potential (ERP) components, the Late Positive Potential (LPP) and the Reward Positivity (RewP). Reductions in each of these components have been associated with current symptoms of depression, and in some cases have been shown to differentiate anxious from depressive phenotypes. In this review, I will describe three broad and related approaches we have taken in our research to address a series of interdependent issuess. The first attempts to understand different sources of variation in the LPP and RewP, and how these sources interact with one another. The second tries to identify whether variation in the processes measured by these ERP components might reflect a latent vulnerability to depression and its symptoms, that is evident prior to illness onset. And the third examines the possibility that the processes reflected in the LPP and RewP might play a mechanistic role in the development of depression.

Abstract
BACKGROUND The COVID-19 pandemic and limited access to healthcare professionals pose a serious risk of worsening mental conditions. This study was designed to examine the changes in symptoms of insomnia and depression during the pandemic as compared to before the pandemic, as well as the factors correlated with abovementioned mental state deterioration. METHODS The study was conducted from 1 April to 15 May 2020, on 212 psychiatric outpatients and 207 healthy controls. Participants completed a survey focused on symptoms during and prior to COVID-19 (the Beck Depression Inventory, the Athens Insomnia Scale). The following correlations were analyzed: demographics, social support, work status, income, and possible participants' and their relatives' COVID-19 diagnoses. RESULTS Insomnia and depression severity intensified during the pandemic in both groups and were associated with age, gender, education, employment, and financial status. No correlations between social support nor becoming sick with COVID-19 and insomnia or depression were observed. Maintaining work and enough money for one's own needs were found to be significant protective factors of depression (OR 0.37 and 0.29, respectively). CONCLUSIONS Exacerbation of insomnia and depression during the pandemic needs to be addressed. Economic crisis seems to influence mental state even more than COVID diagnosis among study subjects/relatives.

Abstract
Background: In Malaysia, B40 communities are those with a median monthly household earning of under RM 3166. With the prolonged COVID-19 pandemic and the resulting lockdown, the livelihoods of those in these areas has been severely impacted. This has increased their vulnerability to psychological afflictions and has led to a poorer perception of their quality of life (QoL) in comparison to the rest of the population. We investigated the association between perceived levels of depression, anxiety and stress and their impact on quality of life (QoL) among B40 residents in a low-cost urban housing area in Kuala Lumpur, Malaysia. Methods: A cross-sectional study was conducted between July 2020 and February 2021 in the Seri Pantai housing settlement. The validated Malay versions of the depression, anxiety, and stress scale-21 (DASS-21) and the World Health Organization Quality of Life, brief (WHOQOL-BREF) were distributed to the participants using Google forms. The statistical significance of the association between subscales of depression, anxiety, stress and QoL domains were assessed using the Pearson's correlation test. Results: Of the 180 participants, the majority were Malays (87.2%) and females (82.2%). The average scores were the highest for stress (5.66 ± 4.59) and the score in the environment domain of QoL (59.27 ± 17.23) was the lowest. A statistically significant negative correlation was found between the subscales of DASS-21 and the four domains of the QoL, with the social relationships and psychological domains showing a highly significant association (p < 0.001). The strongest correlation was observed between the psychological domain and depression (r= -.520) followed by psychological domain and stress (r= -.496). Conclusion: The strongest correlation was observed between psychological domain and depression. This suggests a need to address potential devastating mental health consequences of the COVID-19 pandemic and its effect on the QoL of residents in B40 communities.

Abstract
Microorganisms can be found in virtually any environment. In humans, the largest collection of microorganisms is found in the gut ecosystem. The adult gut microbiome consists of more genes than its human host and typically spans more than 60 genera from across the taxonomic tree. In addition, the gut contains the largest number of neurons in the body, after the brain. In recent years, it has become clear that the gut microbiome is in communication with the brain, through the gut-brain axis. A growing body of literature shows that the gut microbiome plays a shaping role in a variety of psychiatric disorders, including major depressive disorder (MDD). In this review, the interplay between the microbiome and MDD is discussed in three facets. First, we discuss factors that affect the onset/development of MDD that also greatly impinge on the composition of the gut microbiota-especially diet and stressful life events. We then examine the interplay between the microbiota and MDD. We examine evidence suggesting that the microbiota is altered in MDD, and we discuss why the microbiota should be considered during MDD treatment. Finally, we look toward the future and examine how the microbiota might become a therapeutic target for MDD. This review is intended to introduce those familiar with the neurological and psychiatric aspects of MDD to the microbiome and its potential role in the disorder. Although research is in its very early days, with much yet to be the understood, the microbiome is offering new avenues for developing potentially novel strategies for managing MDD.

Abstract
Under stressful conditions, the hypothalamic-pituitary-adrenal (HPA) axis acts to promote transitory physiological adaptations that are often resolved after the stressful stimulus is no longer present. In addition to corticosteroids (e.g., cortisol), the neurosteroid allopregnanolone (3α,5α-tetrahydroprogesterone, 3α-hydroxy-5α-pregnan-20-one) participates in negative feedback mechanisms that restore homeostasis. Chronic, repeated exposure to stress impairs the responsivity of the HPA axis and dampens allopregnanolone levels, participating in the etiopathology of psychiatric disorders, such as major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). MDD and PTSD patients present abnormalities in the HPA axis regulation, such as altered cortisol levels or failure to suppress cortisol release in the dexamethasone suppression test. Herein, we review the neurophysiological role of allopregnanolone both as a potent and positive GABAergic neuromodulator but also in its capacity of inhibiting the HPA axis. The allopregnanolone function in the mechanisms that recapitulate stress-induced pathophysiology, including MDD and PTSD, and its potential as both a treatment target and as a biomarker for these disorders is discussed.

Abstract
During the pandemic, many healthcare professionals (HCPs) are overburdened by work and stress. The aim of the study was to examine alcohol intake, sleep disorders, and depressive symptoms of HCPs during the pandemic in comparison with the pre-pandemic period. Another goal was to indicate risk factors for mental state deterioration and an increase in alcohol use. A cross-sectional survey study was conducted from 1 April to 15 May 2020. HCPs (n = 158) completed questionnaires that probed for symptoms during and prior to the pandemic, including the Beck depression inventory (BDI), Social Support Scale (MOS-SSS), Athens insomnia scale (AIS), and Alcohol Timeline Followback (TLFB) calendar of alcohol consumption. Gender, age, education, marital status, work situation, income, participants’ and relatives’ COVID-19 diagnosis as correlates were analyzed. Depressive symptoms and insomnia became more severe during the pandemic among HCPs, while social support increased. The increase in depressive symptoms was even higher among women (OR 2.78, 95% CI 1.05–7.36; p = 0.04) and was also positively correlated with work reduction (p = 0.02); the presence of sleep disorders was correlated with female gender. Alcohol consumption increased during the pandemic, and was correlated with both more time spent at work and income increase. HCPs involved in the treatment of COVID-19 need support and attention due to the excessive stress load during pandemics, resulting in depression, insomnia, and increased alcohol intake.

Abstract
Mood disorders, including major depressive disorder, can be precipitated by chronic stress. The Y-maze barrier task is an effort-related choice test that measures motivation to expend effort and obtain reward. In mice, chronic stress exposure significantly impacts motivation to work for a higher value reward when a lesser value reward is freely available compared to unstressed mice. Here we describe the chronic corticosterone administration paradigm, which produces a shift in effortful responding in the Y-maze barrier task. In the Y-maze task, one arm contains 4 food pellets, while the other arm contains only 2 pellets. After mice learn to select the high reward arm, barriers with progressively increasing height are then introduced into the high reward arm over multiple test sessions. Unfortunately, most chronic stress paradigms (including corticosterone and social defeat) were developed in male mice and are less effective in female mice. Therefore, we also discuss chronic non-discriminatory social defeat stress (CNSDS), a stress paradigm we developed that is effective in both male and female mice. Repeating results with multiple distinct chronic stressors in male and female mice combined with increased usage of translationally relevant behavior tasks will help to advance the understanding of how chronic stress can precipitate mood disorders.

The Absence of Serotonin in the Brain Alters Acute Stress Responsiveness by Interfering With the Genomic Function of the Glucocorticoid Receptors. Front Cell Neurosci 2020; 14:128.

Abstract
Alterations in serotonergic transmission have been related to a major predisposition to develop psychiatric pathologies, such as depression. We took advantage of tryptophan hydroxylase (TPH) 2 deficient rats, characterized by a complete absence of serotonin in the brain, to evaluate whether a vulnerable genotype may influence the reaction to an acute stressor. In this context, we investigated if the glucocorticoid receptor (GR) genomic pathway activation was altered by the lack of serotonin in the central nervous system. Moreover, we analyzed the transcription pattern of the clock genes that can be affected by acute stressors. Adult wild type (TPH2+/+) and TPH2-deficient (TPH2-/-) male rats were sacrificed after exposure to one single session of acute restraint stress. Protein and gene expression analyses were conducted in the prefrontal cortex (PFC). The acute stress enhanced the translocation of GRs in the nucleus of TPH2+/+ animals. This effect was blunted in TPH2-/- rats, suggesting an impairment of the GR genomic mechanism. This alteration was mirrored in the expression of GR-responsive genes: acute stress led to the up-regulation of GR-target gene expression in TPH2+/+, but not in TPH2-/- animals. Finally, clock genes were differently modulated in the two genotypes after the acute restraint stress. Overall our findings suggest that the absence of serotonin within the brain interferes with the ability of the HPA axis to correctly modulate the response to acute stress, by altering the nuclear mechanisms of the GR and modulation of clock genes expression.

Rubrofusarin Attenuates Chronic Restraint Stress-Induced Depressive Symptoms. Int J Mol Sci 2020; 21:ijms21103454. [PMID: 32414166 PMCID: PMC7278964 DOI: 10.3390/ijms21103454] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 05/11/2020] [Accepted: 05/11/2020] [Indexed: 11/28/2022] Open
Abstract
The aim of this study was to examine whether rubrofusarin, an active ingredient of the Cassia species, has an antidepressive effect in chronic restraint stress (CRS) mouse model. Although acute treatment using rubrofusarin failed, chronic treatment using rubrofusarin ameliorated CRS-induced depressive symptoms. Rubrofusarin treatment significantly reduced the number of Fluoro-Jade B-positive cells and caspase-3 activation within the hippocampus of CRS-treated mice. Moreover, rubrofusarin treatment significantly increased the number of newborn neurons in the hippocampus of CRS-treated mice. CRS induced activation of glycogen synthase kinase-3β and regulated development and DNA damage responses, and reductions in the extracellular-signal-regulated kinase pathway activity were also reversed by rubrofusarin treatment. Microglial activation and inflammasome markers, including nod-like receptor family pyrin domain containing 3 and adaptor protein apoptosis-associated speck-like protein containing CARD, which were induced by CRS, were ameliorated by rubrofusarin. Synaptic plasticity dysfunction within the hippocampus was also rescued by rubrofusarin treatment. Within in vitro experiments, rubrofusarin blocked corticosterone-induced long-term potentiation impairments. These were blocked by LY294002, which is an Akt inhibitor. Finally, we found that the antidepressant effects of rubrofusarin were blocked by an intracerebroventricular injection of LY294002. These results suggest that rubrofusarin ameliorated CRS-induced depressive symptoms through PI3K/Akt signaling.

Abstract
OBJECTIVE To assess health outcomes of parents caring for children with chronic illnesses compared with parents of healthy children. STUDY DESIGN We searched OvidSP MEDLINE, EBM Reviews-Cochrane Central Register of Controlled Trials, EMBASE, and EBSCOHost CINAHL through September 2019. Included were English-language studies reporting health conditions or mortality of parents of affected children compared with healthy controls. RESULTS Of 12 181 screened publications, 26 met inclusion criteria. Eight studies reported on anxiety, 23 on depression, 1 on mortality, and 1 on cardiovascular disease. Parents of chronically ill children had greater anxiety (standardized mean difference 0.42; 95% CI 0.24-0.60; P < .001) and depression scores (standardized mean difference 0.35; 95% CI 0.26-0.45; P < .001) than parents of healthy children. Thirty-five percent of parents of affected children met cut-offs for clinical depression, compared with 19% in the control (relative risk 1.75; 95% CI 1.55-1.97). Fifty-seven percent of such parents met cut-offs for anxiety, compared with 38% in the control (relative risk 1.40; 95% CI 1.18-1.67). One study of mothers of children with congenital anomalies reported a greater mortality risk than a comparison (adjusted hazard ratio 1.22; 95% CI 1.15-1.29), and another reported that these mothers experience an increased risk of cardiovascular disease (adjusted hazard ratio 1.15; 95% CI 1.07-1.23). CONCLUSIONS Parents of chronically ill children experience poorer mental health (more anxiety and depression), and mothers of those with congenital anomalies may have greater risk of cardiovascular disease and mortality than parents of unaffected children. Our findings suggest a need for targeted interventions to attenuate adverse parental caregiver health outcomes.

Abstract
Qualitative methods were used to explore mothers' perceptions of structural family therapy (SFT) delivered in a semi-rural community mental health clinic. In-depth, semi-structured interviews were conducted with sixteen mothers who received SFT after seeking services for their children. Thematic analysis suggests mothers found SFT acceptable and valuable. Mothers reported using SFT strategies to regain parental authority, which they believed improved their ability to manage their child's needs and decreased their own stress. SFT also increased some mothers' receptivity to individual treatment. Mothers identified their low dose of treatment and lack of father involvement as impediments to improvement, raising concerns about intervention sustainability.

Abstract
Depression is increasingly recognized as an inflammatory disease, with inflammatory crosstalk in the brain contributing its pathogenesis. Life stresses may up-regulate inflammatory processes and promote depression. Although cytokines are central to stress-related immune responses, their contribution to stress-induced depression remains unclear. Here, we used unpredictable chronic mild stress (UCMS) to induce depression-like behaviors in mice, as assessed through a suite of behavioral tests. C-X-C motif chemokine ligand 1 (CXCL1)-related molecular networks responsible for depression-like behaviors were assessed through intrahippocampal microinjection of lenti-CXCL1, the antidepressant fluoxetine, the C-X-C motif chemokine receptor 2 (CXCR2) inhibitor SB265610, and the glycogen synthase kinase-3β (GSK3β) inhibitor AR-A014418. Modulation of apoptosis-related pathways and neuronal plasticity were assessed via quantification of cleaved caspase-3, B-cell lymphoma 2-associated X protein, cAMP response element-binding protein (CREB), and brain-derived neurotrophic factor (BDNF) protein expression. CXCL1/CXCL2 expression was correlated with depression-like behaviors in response to chronic stress or antidepressant treatment in the UCMS depression model. Intrahippocampal microinjection of lenti-CXCL1 increased depression-like behaviors, activated GSK3β, increased apoptosis pathways, suppressed CREB activation, and decreased BDNF. Administration of the selective GSK3β inhibitor AR-A014418 abolished the effects of lenti-CXCL1, and the CXCR2 inhibitor SB265610 prevented chronic stress-induced depression-like behaviors, inhibited GSK3β activity, blocked apoptosis pathways, and restored BDNF expression. The CXCL1/CXCR2 axis appears to play a critical role in stress-induced depression, and CXCR2 is a potential novel therapeutic target for patients with depression.-Chai, H.-H., Fu, X.-C., Ma, L., Sun, H.-T., Chen, G.-Z., Song, M.-Y., Chen, W.-X., Chen, Y.-S., Tan, M.-X., Guo, Y.-W., Li, S.-P.

Inhibitory effect of yokukansan on the decrease in the hippocampal excitatory amino acid transporter EAAT2 in stress-maladaptive mice. J Tradit Complement Med 2017; 7:371-374.

Abstract
Chronic stress is widely recognized as a risk factor for the development of major depression and anxiety disorders. Recently, we reported that yokukansan (YKS), a traditional Japanese herbal medicine, alleviated emotional abnormality in stress-maladaptive mice. The aim of the present study was to examine the effect of YKS on the expression of excitatory amino acid transporter (EAAT) 1–4 in the prefrontal cortex and hippocampus in stress-maladaptive mice. Mice were chronically exposed to inadaptable stress, i.e. repeated restraint stress for 240 min/day for 14 days. After the final exposure to stress, brains of mice were rapidly removed and the hippocampus and prefrontal cortex were dissected. Expressions of EAAT1-4 and glial fibrillary acidic protein (GFAP), a marker of astrocytes, in the brain tissues were analyzed by western blotting. Western blot analysis revealed that the expression level of EAAT2 was specifically decreased in the hippocampus of stress-maladaptive mice while there were no changes in the level of GFAP, and this change was inhibited by chronic treatment with YKS. In contrast, no changes were observed in the levels of EAAT1, EAAT3 or EAAT4 in stress-maladaptive mice. These results suggest that YKS may protect against the decrease in hippocampal EAAT2 expression induced by stress maladaptation, and this may contribute, at least in part, to the improvement of emotional abnormality.

Abstract
Post-traumatic stress disorder (PTSD) is a disabling psychiatric condition that can develop following a physical, psychological, or sexual trauma. Despite the growing body of literature examining the psychological and biological factors involved in PTSD psychopathology, specific biomarkers that may improve diagnosis and treatment of PTSD have yet to be identified and validated. This challenge may be attributed to the diverse array of symptoms that individuals with the disorder manifest. Examining the interrelated stress and fear systems allows for a more comprehensive study of these symptoms, and through this approach, which aligns with the research domain criteria (RDoC) framework, neural and psychophysiological measures of PTSD have emerged. In this review, we discuss PTSD neurobiology and treatment within the context of fear and stress network interactions and elucidate the advantages of using an RDoC approach to better understand PTSD with fear conditioning and extinction paradigms.

Abstract
This article presents an evaluation of a multi-element parent and family support intervention for parents of school-aged persons with severe disabilities. Using an experimental design, we compared two randomly assigned groups of parents: one group received a modest level of support consisting of respite care and case management, and the second group received an intensive intervention that consisted of stress management and parenting skills training, support groups, and additional community-based respite care. Separate MANCOVA analyses were conducted for mothers and fathers. Mothers showed significant improvement on measures of depression and anxiety. Further analysis of the data revealed that a significantly greater number of intensive support group members also achieved clinically significant improvement on measures of anxiety and depression. Fathers participated in smaller numbers than mothers. A power analysis revealed large treatment effects for fathers as well as mothers although, due to the small sample size, the results for fathers were significant at p = 0.07. Analyses of 1-year follow-up data revealed that treatment gains maintained for mothers. We discuss the results and limitations of this study in light of current efforts to create family support services nationwide.

Abstract
Qualitative research methods were used to investigate the sources and methods of dealing with stress in six families with adopted children who have severe developmental or multiple disabilities. These families had adopted from 2 to 28 children. Most of the families also included “birth children” and two included a foster child. Participant observation was used with the families and unstructured interviews were conducted with parents, adoption agency workers, state children's welfare workers, and counselors working with adoptive families. Management of daily household tasks and child care routines were not identified as stressful. However, interactions with school and medical personnel and other professionals were extremely stressful for all families interviewed, as were the difficulty in accessing appropriate services and concern about the availability of future services. Parents also identified medical crises and crises resulting from adolescents' behavior problems as time-limited stressful situations. Effective stress management techniques included household organizational systems and maintaining contact with other families with adopted children that have disabilities. In addition, a positive appraisal of their life circumstances appeared to contribute to the families' successful adjustment to potentially stressful situations. Implications for providing support to families with children with special needs, both adopted and nonadopted, are suggested.

Abstract
MicroRNAs (miRNAs) are small, non-coding RNAs acting as post-transcriptional regulators of gene expression. Though implicated in multiple CNS disorders, miRNAs have not been examined in any psychiatric disease state in anterior cingulate cortex (AnCg), a brain region centrally involved in regulating mood. We performed qPCR analyses of 29 miRNAs previously implicated in psychiatric illness (major depressive disorder (MDD), bipolar disorder (BP) and/or schizophrenia (SZ)) in AnCg of patients with MDD and BP versus controls. miR-132, miR-133a and miR-212 were initially identified as differentially expressed in BP, miR-184 in MDD and miR-34a in both MDD and BP (although none survived multiple correction testing and must be considered preliminary). In silico target prediction algorithms identified putative targets of differentially expressed miRNAs. Nuclear Co-Activator 1 (NCOA1), Nuclear Co-Repressor 2 (NCOR2) and Phosphodiesterase 4B (PDE4B) were selected based upon predicted targeting by miR-34a (with NCOR2 and PDE4B both targeted by miR-184) and published relevance to psychiatric illness. Luciferase assays identified PDE4B as a target of miR-34a and miR-184, while NCOA1 and NCOR2 were targeted by miR-34a and 184, respectively. qPCR analyses were performed to determine whether changes in miRNA levels correlated with mRNA levels of validated targets. NCOA1 showed an inverse correlation with miR-34a in BP, while NCOR2 demonstrated a positive correlation. In sum, this is the first study to demonstrate miRNA changes in AnCg in psychiatric illness and validate miR-34a as differentially expressed in CNS in MDD. These findings support a mechanistic role for miRNAs in the regulation of stress-responsive genes disrupted in psychiatric illness.

Abstract
The sleep patterns of 45 mothers of children with moderate to severe multiple disabilities, 45 mothers of children with Down syndrome, and 45 mothers of typically developing children were compared by means of a 7-day diary. The children ranged in age from 6 months to 5 years. The Caregiver's Activity and Recording of Events (CARE) Inventory was completed by each subject to record mothers' activities in half-hour segments throughout a 24-hour day. Activities were coded into nine categories including rest/sleep. The three groups of mothers were compared on total hours of rest/sleep per day, number of sleep interruptions, reason for sleep interruptions, influences of siblings of target children, and number of times the father attended to the target child during the night as perceived by the mother. Surprisingly, the results indicated that mothers of children with multiple disabilities reported more sleep than did mothers in the other two groups. There were no significant differences found among the groups in the following: amount of weekly daytime sleep; frequency and duration of child-related interruptions per week; number of nights of uninterrupted sleep per week; maximum number of sleep interruptions in one night; and mothers' perception of fathers' nighttime assistance. The data indicated that many mothers in all three groups experienced numerous weekly sleep interruptions, particularly mothers of infants 6 to 12 months of age. Professionals working with mothers of young children must consider the effects of shortened and interrupted sleep patterns on the day time functioning and health of mothers and the effect on the well-being of the entire family.

Abstract
Corticotropin-releasing factor (CRF), a 41 amino acid-containing neuropeptide, acts both as a hypothalamic releasing factor, controlling ACTH and corticosteroid secretion, and at extrahypothalamic CNS sites to mod ulate mammalian organisms' responses to stress. In this article, the evidence that CRF-containing neurons within the CNS are hyperactive in patients with depression is reviewed. The evidence, taken together, suggests that during depressive episodes, CRF is hypersecreted, resulting in both pituitary-adrenal axis hyperactivity and certain of the signs and symptoms of depression, including decreased appetite, decreased libido and disturbed sleep. There is also evidence that treatments for depression, including antidepressant medications and electroconvulsive therapy, reduce CRF hypersecretion within the CNS. Finally, evidence suggests that alterations in CRF-containing neurons and receptors are responsible for the widely held ob servation that early untoward life events increase an individual's vulnerability for affective disorders. These findings have a number of implications for treatment of the mood disorders, including the suggestion that the pharmacological manipulation of CRF receptors may provide a novel avenue for the treatment of de pression.

Abstract
Changes in the perceived self-images and coping strategies of mothers of children with special needs after they participated in a short-term occupational therapy intervention (Project Bien Estar) are discussed. We conducted focus groups to ascertain whether women's coping strategies and views of themselves had changed as a result of participation in the program. The results of this study found that participating in Project Bien Estar enabled participants to share their perceptions of their self-image such as feeling overwhelmed with their daily care routine, being socially isolated, losing their identity, and expecting less from their careers. Participants expressed that participating in the program helped them to feel strong, attractive, resilient, respected, and accepted. After participating in the program, they expressed they had gained coping skills such as increased ability to advocate for themselves and their child, more relaxed expectations about their responsibilities and what is needed to care well for their child, and increased self-care practices.

Abstract
Strong evidence has shown that caffeine exerts antidepressant-like effects in chronic stress situations by increasing dopamine levels. However, whether caffeine mediates the dopaminergic system and interferes with the resilience to social defeat stress in mice is unknown. The aim of this study is to investigate the role of caffeine in the behavioral responses to social defeat stress and the possible regulatory role of the dopaminergic system. Mice experienced chronic social defeat stress for 10 days. Caffeine was administered intraperitoneally before, during and after social defeat stress. The time spent in interaction zone, social interaction ratio and sucrose preference test was used to measure the social avoidance and anhedonia in mice. The results showed that chronic pretreatment with caffeine for 14 days and for 10 days during stress reversed the avoidance of social behavior and anhedonia induced by social defeat stress in mice, suggesting the enhancement of the resilience to social defeat stress induced by caffeine. However, neither the treatment with caffeine only during the social defeat stress for 10 days nor the treatment with acute caffeine after defeat stress altered the resilience to stress. Furthermore, chronic caffeine treatment did not affect the normal locomotor activity and the desperate behavior in naïve mice. Moreover, the antagonism of dopamine D1 receptor and not D2 receptor reversed the effect of caffeine on the social avoidance and depressive-like behavior. Finally, pretreatment with higher doses of caffeine did not affect the behavioral response to social defeat stress. Taken together, our findings provide new insight into the effects of caffeine on social avoidance and anhedonia in mice. In addition, our results illustrated the value of measuring changes in depressive-like behavior before and after social defeat stress to determine the potential treatment of caffeine on depression through the regulation of dopaminergic system.

Abstract
The objectives of this study are to evaluate the employee benefits parents of children with autism spectrum disorders have, how benefits are used, work change, and job satisfaction. We conducted a cross-sectional mailed survey study of 435 families with children with autism spectrum disorders residing in the United States. We received 161 surveys for a response rate of 37%. Families reported using the following benefits: 39% paid family leave, 19% unpaid family leave, 91% flexible work arrangements, and 86% telecommuting. Of respondents, 43% reported stopping work, cutting down on hours worked, or changing jobs because of their child’s condition. Having paid family leave was a positive predictor for job satisfaction. Parents of children with autism spectrum disorders have an interest and need for alternative work arrangements.

Abstract
OBJECTIVE To review the current evidence about the neurobiological mechanisms in major depressive disorders (MDD) and the key findings from studies using neuroimaging tools and animal models. METHOD This paper gives an overview of the role of genetic and environmental factors in the pathophysiology of MDD and describes the structural changes in brain structures of depressed individuals. A closer look is given at the molecular processes and neurotransmitters implicated in this mental disorder. Moreover, this paper discusses key findings from recent research using animal models and their relevance for clinical applications. RESULTS Although the exact cause of MDD is not known, there is enough evidence showing that genetic, psychological and environmental factors significantly increase the risk of developing this disease. Individuals affected by MDD exhibit a reduced volume of structures such as the amygdala, hippocampus and basal ganglia, as well as altered level of neurotransmitters in the brain. CONCLUSION The studies presented in this review show promising results that could shed light on the molecular mechanisms of MDD. However, more work needs to be done to better understand this psychiatric disorder and promote the development of new treatment strategies.

Abstract
Accumulating evidence has shown that a polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) moderates the association between stress and depressive symptoms. However, the exact etiologies underlying this moderation are not well understood. Here it is reported that among adult female rhesus macaques, an orthologous polymorphism (rh5-HTTLPR) exerted an influence on cortisol responses to chronic stress. It was found that females with two copies of the short allele were associated with increased cortisol responses to chronic stress in comparison to their counterparts who have one or two copies of the long allele. In the absence of stress, no differences related to genotype were observed in these females. This genetic moderation was found without a genetic influence on exposure to stressful situations. Rather it was found to be a genetic modulation of cortisol responses to chronic stress. These findings indicate that the rh5-HTTLPR polymorphism is closely related to hypothalamus-pituitary-adrenal (HPA) axis reactivity, which may increase susceptibility to depression in females with low serotonin transporter efficiency and a history of stress.

Abstract
Low-income caregivers of children with asthma experience multiple stressors, likely worsening family health. As part of Community Action Against Asthma's community-based participatory research partnership, researchers conducted 40 qualitative semi-structured interviews and quantitative surveys with low-income caregivers of children with asthma in Detroit, Michigan. Participants described daily childhood asthma experiences and completed scales including the Peds Quality of Life Family Impact Module and Zarit Burden Caregiver Scale. Quantitative scale findings suggested participants are moderately stressed or affected by their child's illness. While there was some accordance between qualitative and quantitative findings, qualitative findings additionally captured many relevant life stressors, seemingly overlooked or conflated in scale responses. Many participants described asthma as part of childrearing, rather than as a stressor or burden. Findings encourage improvement of clinical, psychometric assessments used to measure and address stressors that shape health for many families with children with asthma.

Abstract
The seeds of Nigella sativa L., commonly known as black seed or black cumin, and its extracts are used in folk medicine in the Middle East and in Asian countries for the promotion of good health and as a remedy for many ailments. These seeds have many acclaimed medicinal properties such as broncho-dilatory, immunopotentiating, analgesic, anti-inflammatory, and hypotensive. In the present study, the antidepressant activity following the repeated administration of Nigella sativa L. oil has been monitored using the forced swim test. Rats treated with Nigella sativa L. oil exhibited a significant increase in struggling time after oral administration of Nigella sativa L. oil (0.1 ml/kg/day) for four weeks. Nigella sativa L. oil increased brain 5-HT levels and decreased 5-HT turnover (5-HT/5-HIAA ratio). Levels of tryptophan increased significantly in the brain and plasma following the repeated administration of Nigella sativa L. oil. Nigella sativa L. oil showed a potential antidepressant-like effect.

Abstract
The current study examined demographic and psychosocial factors that predict major depressive disorder (MDD) and comorbid MDD/posttraumatic stress disorder (MDD/PTSD) diagnostic status after Hurricane Katrina, one of the deadliest and costliest hurricanes in the history of the United States. This study expanded on the findings published in the article by Galea, Tracy, Norris, and Coffey (J Trauma Stress 21:357-368, 2008), which examined the same predictors for PTSD, to better understand related and unique predictors of MDD, PTSD, and MDD/PTSD comorbidity. A total of 810 individuals representative of adult residents living in the 23 southernmost counties of Mississippi before Hurricane Katrina were interviewed. Ongoing hurricane-related stressors, low social support, and hurricane-related financial loss were common predictors of MDD, PTSD, and MDD/PTSD, whereas educational and marital status emerged as unique predictors of MDD. Implications for postdisaster relief efforts that address the risk for both MDD and PTSD are discussed.

Abstract
Dysregulated stress responsivity is a hallmark of neuropsychiatric disease. The regulation of stress activation and recovery involves tight coordination between neuronal and glial networks. At a certain threshold of sensitivity, stress exposure can evoke a neuroimmune response. Astrocytes are potential mediators of these effects because they are able to respond to neuroimmune effector molecules and regulate neuronal activity. Mice deficient in corticotropin-releasing factor receptor-2 display increased stress sensitivity and are therefore a useful model in which to examine the intersection of neuroimmune activation and stress pathway dysregulation. We hypothesized that a component of elevated stress reactivity may involve an engagement of neuroimmune effectors, including astrocytes. Therefore, we hypothesized that this phenotype may be rescued by concomitant nonsteroidal antiinflammatory drug (NSAID) treatment. To examine this, mice exposed to chronic stress were treated with NSAID in their drinking water, and changes in hypothalamic-pituitary-adrenal stress axis function were examined. As a correlate of altered astrocyte function, levels of glial fibrillary acidic protein were measured. Supportive of our hypothesis, NSAID treatment rescued the hypothalamic-pituitary-adrenal stress axis dysfunction in stress-sensitive corticotropin-releasing factor receptor-2(-/-) mice and also reversed the stress-induced increase in glial fibrillary acidic protein in stress-regulating brain regions including the paraventricular nucleus of the hypothalamus, ventral hippocampus, and prefrontal cortex. These findings support the local involvement of astrocytes in the exacerbation of stress pathway dysregulation. The specificity of these effects in a stress-sensitive genotype highlights the importance of utilizing a model of stress dysregulation in the examination of factors that may translate to neuropsychiatric disease.

Abstract
Various kinds of stress are thought to precipitate psychiatric disorders, such as major depression. Whereas studies in rodents have suggested a critical role of medial prefrontal cortex (mPFC) in stress susceptibility, the mechanism of how stress susceptibility is determined through mPFC remains unknown. Here we show a critical role of prostaglandin E(2) (PGE(2)), a bioactive lipid derived from arachidonic acid, in repeated social defeat stress in mice. Repeated social defeat increased the PGE(2) level in the subcortical region of the brain, and mice lacking either COX-1, a prostaglandin synthase, or EP1, a PGE receptor, were impaired in induction of social avoidance by repeated social defeat. Given the reported action of EP1 that augments GABAergic inputs to midbrain dopamine neurons, we analyzed dopaminergic response upon social defeat. Analyses of c-Fos expression of VTA dopamine neurons and dopamine turnover in mPFC showed that mesocortical dopaminergic pathway is activated upon social defeat and attenuated with repetition of social defeat in wild-type mice. EP1 deficiency abolished such repeated stress-induced attenuation of mesocortical dopaminergic pathway. Blockade of dopamine D1-like receptor during social defeat restored social avoidance in EP1-deficient mice, suggesting that disinhibited dopaminergic response during social defeat blocks induction of social avoidance. Furthermore, mPFC dopaminergic lesion by local injection of 6-hydroxydopamine, which mimicked the action of EP1 during repeated stress, facilitated induction of social avoidance upon social defeat. Taken together, our data suggest that PGE(2)-EP1 signaling is critical for susceptibility to repeated social defeat stress in mice through attenuation of mesocortical dopaminergic pathway.

Abstract
In the current review, we highlight recent research on marital quality in parents of children with developmental disabilities (DD) and discuss the child and family factors that account for why some marriages fare better than others. We will also discuss the need for the field of DD to broaden its perspective on marital quality and to examine the impact of marriages on child well-being and the well-being of parents. The clinical implications of recent research findings on marital quality for improving supports and interventions for families of children with DD are discussed. A theoretical framework and model of marriage and parent and child psychosocial well-being in the context of child disability is proposed and a roadmap for future research is provided.

Abstract
Stressful life events increase the susceptibility for subsequent onset of psychiatric disorders in humans. Previous research has implicated neurotrophins in the onset of some stress-related diseases, such as major depression disorder, post-traumatic stress disorder or panic disorder. We have tested the hypothesis that the neurotrophin-3 (NT-3)/TrkC system is a genetic interface mediating the deleterious effects of stress on the initiation of panic disorder and other pathologies. To this aim, we have analyzed the functionality of HPA axis and the behavioral consequences of different types of stressful conditions in a mouse model of panic disorder, which overexpresses TrkC, the high affinity-receptor for NT-3 (TgNTRK3). Our results reveal that TgNTRK3 mice exhibit an altered circadian corticosterone rhythm that is reversed by clonidine treatment, but normal expression of genes involved in the control of the hypothalamus-pituitary-adrenal (HPA) axis (CRH, GR) and normal corticosterone response to acute and chronic stressors. In contrast, they exhibit an altered pattern of activation of stress-related brain areas and showed enhanced anxiety-related behavior and more passive strategies than wild types under some chronic stress conditions. We conclude that TgNTRK3 mice present differences in their response to stress characterized by subtle changes in the HPA axis, marked changes in acute stress-induced brain activation and altered coping strategies, suggesting a key role of TrkC receptor in the stress neural circuitry and in the behavioral consequences of chronic stress.

Abstract
PURPOSE Children with neurodevelopmental disorders (Neuro) pose complex parenting challenges, particularly if the condition co-occurs with behaviour problems. Such challenges are likely to impact caregiver health and well-being. This study explores the extent to which caregivers of children with both 'Neuro' and behaviour problems differ in their physical and psychosocial outcomes from caregivers of children with either condition or neither condition. METHOD The first wave of data collected in the National Longitudinal Survey of Children and Youth in Canada (1994) was used to identify four groups of caregivers of 4 to 11-year-old children: caregivers of children with a 'Neuro' disorder and externalising behaviour problems (Both; n=414), caregivers of children with a 'Neuro' disorder only (Neuro Only; n=750), caregivers of children with an externalising behaviour problem only (Ext Only; n=1067), and caregivers of children with neither health condition (Neither; n=7236). RESULTS Caregivers in the 'Both' group were least likely to report excellent or very good health, and more frequently reported chronic conditions such as asthma, arthritis, back problems, migraine headaches, and limitations in activities as compared to the 'Neither' group. This group also exhibited higher depression scores, experienced more problematic family functioning, and reported lower social support than the 'Neither' group. Scores for caregivers in the 'Ext Only' and 'Neuro Only' groups tended to lie between the 'Both' and 'Neither' group scores and often did not differ from one another. CONCLUSIONS Caregivers of children with both neurodevelopmental disorders and behaviour problems exhibited a greater number of health and psychosocial problems. While addressing children's behaviour problems, health care professionals should also consider caregiver physical and psychosocial health as this may also have an impact on children's well-being.

Abstract
8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT), a selective 5-hydroxy-tryptamine (5-HT; serotonin)-1A agonist was used to evaluate the role 5-HT-1 A receptors in restraint-induced behavioral deficits and adaptation to repeated restraint stress in rats. Animals were injected with 8-OH-DPAT at a dose of 0.25 mg/kg 1 h before exposing to an episode of 2 h/day restraint stress daily for 5 days. Effects of drug administration and restraint stress on 24 h cumulative food intakes were monitored daily. Intensity of 8-OH-DPAT-induced serotonin syndrome was also monitored each day before submitting animals to the episode of stress. Exposure to the first episode of 2 h restraint stress resulted in a decrease in 24 h cumulative food intake and an attenuation of 8-OH-DPAT-induced serotonin syndrome monitored next day. The deficits attenuated following 2nd and 3rd 2 h/day restraint were not observed following the 4th and 5th 2 h/day restraint. The decreases of food intake following 1st and 2nd day restraint sessions were smaller in 8-OH-DPAT than saline-injected animals. Administration of 8-OH-DPAT on day 6 elicited comparable serotonin syndrome in unrestrained and repeatedly restrained groups. Brain 5-HT metabolism decreased in unrestrained but not repeatedly restrained animals. The results suggest that a decrease in serotonergic neurotransmission is involved in restraint-induced behavioral deficits while a normalization of serotonin neurotransmission due to desensitization of somatodendritic 5-HT-1A receptors may help cope with the stress demand to produce adaptation to stress.

Abstract
The extent of intrusive traumatic memories of upsetting childhood experiences was investigated in independent samples of female subjects: out-patients with a primary diagnosis of unipolar major depression, women recovered from clinical depression, and healthy controls who had never experienced major depression. Subjects completed self-report questionnaires to measure levels of depression, and intrusive memories of traumatic childhood events. There were no differences between the groups in whether or not they experienced intrusive memories, but severity of intrusions varied significantly. The depressed sample reported significantly more intrusion and avoidance than the recovered or control groups, and the recovered sample reported normal levels of intrusion but higher levels of avoidance of traumatic memories than controls. Severely depressed subjects reported significantly higher levels of intrusion and avoidance than moderately depressed subjects. Implications for psychological models and for the treatment of depression are discussed.

Abstract
Major depressive disorder causes significant morbidity, affecting people's ability to work, function in relationships, and engage in social activities. Moreover, major depressive disorder increases the risk of suicidal ideation, attempted suicide and death by completed suicide. There is evidence that chronic stress can cause major depressive disorder. As for genetic factors, only minor susceptibility genes have been reliably identified. The serotonin system provides a logical source of susceptibility genes for depression, because this system is the target of selective serotonin reuptake-inhibitor drugs that are effective in treating depression. The 5-hydroxytryptamine (serotonin) transporter (5-HTT) has received particular attention because it is involved in the reuptake of serotonin at brain synapses. One common polymorphic variant of the 5-HTT-linked polymorphic region (5-HTTLPR), which affects the promoter of the 5-HTT gene, causes reduced uptake of the neurotransmitter serotonin into the presynaptic cells in the brain. The authors discussed the relationship between genetic polymorphisms and major depressive disorder, with special emphasis on the 5-HTTTLPR polymorphism. As the 5-HTTLPR polymorphism was significantly associated with an increased risk of major depressive disorder, the 5-HTT gene may be a candidate for a major depressive disorder susceptibility gene. As major depressive disorder is a multifactorial disease, an improved understanding of the interplay of environmental and genetic polymorphisms at multiple loci may help identify individuals who are at increased risk for major depressive disorder. Hopefully, in the future we will be able to screen for major depressive disorder susceptibility by using specific biomarkers.

Abstract
BACKGROUND The Child Abuse Blame Scale - Physical Abuse (CABS-PA) was translated into Japanese and its subscale items modified by the authors according to the Japanese cultural context. The aim of the current study was to investigate the appropriateness, reliability, and clinical applicability of the CABS-PA Japanese version (CABS-PA-J). Modifications were made to enable the determination of child abuse recognition in a Japanese cultural setting and early clinical intervention in child abuse cases. METHODS The CABS-PA text was translated into Japanese, then back translated. The appropriateness of scale item translations was verified based on e-mail discussions with the original CABS-PA author. Exploratory and confirmatory factor analyses were performed to examine the validity of CABS-PA-J responses and to confirm the validity of factor structure. Criterion-related validity was also confirmed. The Japanese scale was used to examine the characteristic differences between mothers of premature infants (< 1500 g) and those of other infants (>or= 1500 g). RESULTS Exploratory and confirmatory factor analyses found the factor structure to be similar between the original scale and the translated CABS-PA-J, suggesting adequate factor validity. There was a statistically significant correlation between social support from a spouse or third party and the abuse score on a subscale, partially demonstrating criterion-referenced validity. Similarities and differences were found in the stress reactions of the mothers of premature infants (< 1500 g) and those of other infants (>or= 1500 g). CONCLUSION CABS-PA-J was shown to be appropriate and reliable. It is an effective tool for determining the recognition of child abuse among Japanese mothers.

Abstract
Measurement of posttraumatic brain injury depression is problematic. Disagreement exists about the best screening measure, and symptoms of brain injury often overlap those of depression. In an outpatient sample of 75 persons, we compared aspects of Criterion A of the Diagnostic and Statistical Manual of Mental Disorders--Fourth Revision, Text Revision (2000), with three depression subscales: the Neurobehavioral Functioning (NFI-D), Profile of Moods State (POMS-D), and Center for Epidemiologic Studies (CES-D). Nearly 40% of this outpatient sample had significant levels of depressive symptoms. All measures were internally consistent, reliable, and highly correlated. For persons with mild-to-moderate traumatic brain injury, the CES-D was the best screening instrument because of its ease in administration, sensitivity in detecting probable major depressive disorders, its established categories of severity, and its comprehensiveness. Further effort in the establishment of depression severity categories using the NFI-D is needed.

Abstract
Improved methods of assessment and research design have established a robust and causal association between stressful life events and major depressive episodes. The chapter reviews these developments briefly and attempts to identify gaps in the field and new directions in recent research. There are notable shortcomings in several important topics: measurement and evaluation of chronic stress and depression; exploration of potentially different processes of stress and depression associated with first-onset versus recurrent episodes; possible gender differences in exposure and reactivity to stressors; testing kindling/sensitization processes; longitudinal tests of diathesis-stress models; and understanding biological stress processes associated with naturally occurring stress and depressive outcomes. There is growing interest in moving away from unidirectional models of the stress-depression association, toward recognition of the effects of contexts and personal characteristics on the occurrence of stressors, and on the likelihood of progressive and dynamic relationships between stress and depression over time-including effects of childhood and lifetime stress exposure on later reactivity to stress.

Abstract
Perspectives on humor of families who have a member with a disability were examined using a qualitative methodology. Findings offer complex and challenging lessons for those who work with and for families of children with disabilities. I compared the traditional view that families of children with disabilities go through a constant process of grieving and sadness with newly emerging views of accepting relationships and making life as typical as possible with the help of humor.

Abstract
A substantial and still growing body of research tries to link different psychological models and chronic diseases, with special emphasis on cardiovascular disease. These efforts have established several conceptual bridges that connect psychological alterations and psychosocial factors to the risks, onset and prognosis of cardiovascular disease. However, several different models have been suggested. Depression and learned helplessness are two central psychological models that have been shown to have major explanatory power in the development of chronic diseases. In this respect the so called Central-Eastern European health paradox, that is the morbidity and mortality crisis in these transforming societies can be regarded as a special experimental model. In this review chronic stress is proposed as an integrating theory that can be applied to different psychological models. Chronic stress and allostatic load has been shown to lead to typical pathogenetic results in animal experiments. Chronic stress theory is applicable to the explanation of the suddenly changing patterns of premature mortality rates in transforming societies. Literature and the different models in the field of psychology, behavioural sciences, and epidemiology are reviewed in terms of the chronic stress theory. The applicability of these results are investigated for further research, clinical and policy implications.

Abstract
Psychosocial and biologic mechanisms are implicated in depression after traumatic brain injury (TBI). Using McEwen's stress theory of allostasis as a guidepost, this study examined whether pre- and postinjury chronic stress conditions could explain post-TBI depressive symptoms. Seventy-five community-dwelling persons who sustained a mild-to-moderate TBI and were within 2 years of the injury participated in this cross-sectional study. The participants completed measures of chronic stress and depression, measured with the Neurobehavioral Functioning Inventory. Data were collected also on brain injury severity. Using multiple regression analysis, the frequency of childhood adversities and postinjury stress explained post-TBI depression. When time-since-injury was in the regression model, the frequency of preinjury stressors and postinjury stress significantly explained post-TBI depressive symptoms while the combined effect of childhood adversity with postinjury stress was not significant in explaining depressive symptoms. Pre- and postinjury chronic stress explained post-TBI depressive symptoms. These findings support stress-diathesis theory within the psychiatric literature and a linkage between chronic stress, an indicator of allostatic load, and post-TBI depression. These findings are important for nurse specialists working with persons who sustained brain injury, for chronic stress can be buffered by efficient and effective support systems.
