A person who faces the diagnosis of cancer is subjected to changes within his body, but also with regard to his view of himself and his social relationships. Cancer related psychological distress occurs frequently and has a different prevalence according to-among other factors-cancer type and stage of disease. The main psychiatric disturbances observed in patients with cancer are adjustment disorders and affective disorders (anxiety and depression), which in the majority of patients are due to stressors related to the occurrence and threat of the disease and pre-existing psychological vulnerabilities; however, they might also be a direct consequence of biological causes either resulting from bodily modifications induced by the cancer or from treatment side effects...

BACKGROUND: Adversity during early development has been shown to have enduring negative physiological consequences. In turn, atypical physiological functioning has been associated with maladaptive processing of negative affect, including its regulation. The present study therefore explored whether exposure to adverse life events in childhood predicted maladaptive (less flexible) parasympathetic nervous system functioning during the processing of negative affect among adolescents with depression histories...

The incidence of depression is approximately 2-fold greater in women than men but the biological mechanisms underlying this phenomenon remain unclear. One potential mechanism that has been understudied is immune function, which is modulated by sex hormones and differs considerably between males and females. The immune-regulating kynurenine pathway previously has been implicated in the pathogenesis of mood disorders. In particular, a decreased ratio of neuroprotective (kynurenic acid; KynA) to neurotoxic (3-hydroxykynurenine; 3HK and quinolinic acid; QA) kynurenine pathway metabolites has been reported in several mood disorder subtypes...

While recent 'big data' analyses discovered structural brain networks that alter with age and relate to cognitive decline, identifying modifiable factors that prevent these changes remains a major challenge. We therefore aimed to determine the effects of common cardiovascular risk factors on vulnerable gray matter (GM) networks in a large and well-characterized population-based cohort. In 616 healthy elderly (258 women, 60-80 years) of the LIFE-Adult-Study, we assessed the effects of obesity, smoking, blood pressure, markers of glucose and lipid metabolism as well as physical activity on major GM-networks derived using linked independent component analysis...

Anxiety is highly prevalent in many populations; however, the burden of anxiety disorders amongst pregnant women in low-resource settings is not well documented. We investigated the prevalence and predictors of antenatal anxiety disorders amongst low-income women living with psychosocial adversity. Pregnant women were recruited from an urban, primary level clinic in Cape Town, South Africa. The Mini-International Neuropsychiatric Interview diagnostic interview assessed prevalence of anxiety disorders. Four self-report questionnaires measured psychosocial characteristics...

Evidence continues to build suggesting that the GABAergic neurotransmitter system is altered in brains of patients with major depressive disorder. However, there is little information available related to the extent of these changes or the potential mechanisms associated with these alterations. As stress is a well-established precipitant to depressive episodes, we sought to explore the impact of chronic stress on GABAergic interneurons. Using western blot analyses and quantitative real-time PCR (qPCR) we assessed the effects of five-weeks of chronic unpredictable stress (CUS) exposure on the expression of GABA-synthesizing enzymes (GAD65 and GAD67), calcium-binding proteins (calbindin (CB), parvalbumin (PV) and calretinin (CR)), and neuropeptides co-expressed in GABAergic neurons (somatostatin (SST), neuropeptide Y (NPY), vasoactive intestinal peptide (VIP) and cholecystokinin (CCK)) in the prefrontal cortex (PFC) and hippocampus (HPC) of rats...

Major Depression is a prevalent mental disorder that is characterized by negative mood and reduced motivation, and frequently results in social withdrawal and memory-related deficits. Repeated stressors, such as adverse life events, increase the risk for development of the disorder. Consequently, individual variability in stress response greatly weighs on depression-vulnerability and -resilience. Here, we employed the social defeat-induced persistent stress (SDPS) paradigm to identify depression-prone individuals and to examine the temporal development of depression in the months following exposure to brief defeat stress...

BACKGROUND: Adolescents living with HIV are an emerging group in the global HIV/AIDS epidemic. Mental health in this population affects HIV care, treatment, consequential morbidity and secondary transmission. There is a paucity of research regarding these youth in South Africa (SA), partly because section 71 of the National Health Act of 2003 (NHA) requires parental or guardian's consent. OBJECTIVE: To explore legal and ethical issues related to conducting adolescent mental health research in SA...

This article describes psychiatric emergencies in pregnant women. The perinatal period is a time of psychiatric vulnerability. Up to 1 in 6 pregnant women experience major depressive disorder, and 1 in 4 pregnant women with bipolar disorder experience mood exacerbation. We discuss the management of severe mental illness in pregnancy, risk to mother and child of untreated psychiatric illness in pregnancy, risk of relapse of psychiatric disorders in pregnancy with medication discontinuation, psychopharmacologic considerations of teratogenicity and other fetal adverse effects, acute agitation in the pregnant patient, suicidality in pregnancy, and emergency considerations related to substance use disorders...

OBJECTIVES: The role of inflammation and lipid metabolism in the pathophysiology of suicidal behavior has received particular attention in recent years. The neutrophil-to-lymphocyte ratio (NLR) has been suggested as a new and more reliable indicator of low-grade inflammation. NLR has been found to be altered in major depressive disorder (MDD) and has been related to various factors, including chronic stress and impulsivity that were previously reported to be related to suicidal behavior...

BACKGROUND: Despite success of public health-oriented tobacco control programs in lowering the smoking prevalence over the past several decades, it is unclear whether similar reductions in smoking have been experienced among pregnant women, especially in vulnerable groups such as those with major depression and/or lower socioeconomic status. OBJECTIVES: The purpose of this study is to examine the relationship between major depressive episode (MDE) and smoking among pregnant women overall, and by demographics and to estimate changes in the prevalence of cigarette smoking among pregnant women with and without MDE from 2005 to 2014...

The Life Events and Difficulties Schedule (LEDS) is considered the standard for measuring psychosocial stressor exposure, but it has not been used with academically at-risk adolescents, including high school dropouts. The goal of this study was to (1) adapt the LEDS for use with this population, and (2) examine the reliability (interrater) and validity (concurrent and predictive) of this adaptation among a sample of vulnerable adolescents (N = 545). Good reliability coefficients (.79-.90) were obtained, and stressor exposure was associated with concurrent criteria indexing mental health outcomes (depression) and major risk factors for dropout (administratively recorded and self-reported)...

The comparative strength of the 5-HTTLPR polymorphism as a 'predictor' of depression after major stress, versus the 'protective' effect of psychological resilience (PR) against depression after major stress, was tested in a homogeneous sample of older men who had all received a diagnosis and treatment for prostate cancer. Results supported the association between PR and lower depression after stress, but did not support the association between the 5-HTTLPR and elevated depression after stress. Examination of PR at scale, factor, and item level identified the specific PR-related behaviour that was the most powerful predictor of low depression...

BACKGROUND: Marital status is associated with major depression prevalence, however, the strength of association may be modified by age and gender. METHODS: The data sources were a series of cross sectional national health surveys of the Canadian population carried out by Statistics Canada during 1996-2013. These were cross-sectional files from the National Population Health Survey of 1996, together with the Canadian Community Health Surveys from 2000 to 2013; the respondents were 18 years and older...

J A Gethin, K E Lythe, C I Workman, A Mayes, J Moll, R Zahn
BACKGROUND: There is contradictory evidence regarding negative memory biases in major depressive disorder (MDD) and whether these persist into remission, which would suggest their role as vulnerability traits rather than correlates of mood state. Early life stress (ELS), common in patients with psychiatric disorders, has independently been associated with memory biases, and confounds MDD versus control group comparisons. Furthermore, in most studies negative biases could have resulted from executive impairments rather than memory difficulties per se...

BACKGROUND: Tobacco smoking is a health care issue in developed as well as in developing countries. Tobacco smoking among people with mental illness is significantly higher than in the general population. Tobacco smoking has negative effects on physical, mental and financial well-being of people with mental illness but little is known about tobacco dependence among mental health service users in sub-Saharan African countries, including Ethiopia. Therefore, this study attempted to assess the prevalence of tobacco dependence and associated factors among mental health service users at Jimma University teaching hospital...

Extensive data highlight the existence of major differences in individuals' susceptibility to stress [1-4]. While genetic factors [5, 6] and exposure to early life stress [7, 8] are key components for such neurobehavioral diversity, intriguing observations revealed individual differences in response to stress in inbred mice [9-12]. This raised the possibility that other factors might be critical in stress vulnerability. A key challenge in the field is to identify non-invasively risk factors for vulnerability to stress...
