BACKGROUND: Women are at greater risk than men of developing depression and comorbid disorders such as cardiovascular disease. This enhanced risk begins at puberty and ends following menopause, suggesting a role for ovarian hormones in this sensitivity. Here we used a model of psychosocial witness stress in female rats to determine the stress-induced neurobiological adaptations that underlie stress susceptibility in an ovarian hormone-dependent manner. METHODS: Intact or ovariectomized (OVX) female rats were exposed to five daily 15-minute witness-stress exposures...

We aim to investigate some of the pathogenetic mediators of the human echinococcosis and to obtain updated epidemiological findings on cases of echinococcosis in Calabria, Southern Italy. Echinococcosis diagnosis was based on imaging, serological investigations, and molecular assay. Indeed, real-time PCR indicated the presence of G2/G3 genotypes of Echinococcus granulosus complex. Regarding pathogenesis, a relevant novel tool of immune depression should be deemed the reduced level of serum MCP-1. Also, we found a previously unreported VEGF, possibly associated with neovascularization requested by the parasite cyst metabolism...

BACKGROUND: Regular exercise in adults improves depressive symptoms (DS) and major depressive disorder (MDD), however the clinical effects of ceasing exercise are largely unknown. METHODS: Seven databases were searched from inception to December 2017. Eligibility criteria included English language studies investigating the effects of ceasing exercise on DS or MDD in regularly active adults with or without prior DS or MDD. Blood based markers related to exercise cessation (EC) were assessed, if recorded...

PROBLEM: Psychiatric disorders and stress in women have been associated with poor IVF outcome. We hypothesized that both partners in the infertile couples are emotionally affected, and cytokines in both may link psychological to reproductive outcome. METHOD OF STUDY: Forty-five IVF couples completed questionnaires and visual analog scales for stress and psychiatric disorders and had cytokines measured in serum, semen, cervicovaginal, and follicular fluids. Multivariable analyses, t tests, maximum likelihood estimates, Spearman correlation, and data mining were applied...

Exposure to stressors can enhance neuroinflammatory responses, and both stress and neuroinflammation are predisposing factors in the development of psychiatric disorders. Females suffer disproportionately more from several psychiatric disorders, yet stress-induced changes in neuroinflammation have primarily been studied in males. Here we tested whether exposure to inescapable tail shock sensitizes or 'primes' neuroinflammatory responses in male and female rats. At 24 h post-stress, male and female rats exposed to a peripheral immune challenge enhanced neuroinflammatory responses and exacerbated anxiety- and depressive-like behaviors...

Persistent fatigue is a common problem (∼20-45% of U.S. population), with higher prevalence and severity in people with medical conditions such as cancer, depression, fibromyalgia, heart failure, sleep apnea and multiple sclerosis. There are few FDA-approved treatments for fatigue and great disagreement on how to measure fatigue, with over 250 instruments used in research. Many instruments define fatigue as "a lack of energy", thus viewing energy and fatigue states as opposites on a single bipolar continuum...

Expression of TPH2, the rate-limiting enzyme for brain serotonin synthesis, is elevated in the dorsal raphe nucleus (DR) of depressed suicide victims. One hypothesis is that this increase in TPH2 expression is stress-induced. Here, we used an established animal model to address whether exposure to an acute stressor, inescapable tail shock (IS), increases tph2 mRNA and Tph2 protein expression, and if IS sensitizes the DR to a subsequent, heterotypic stressor. In Experiment 1 , we measured tph2 mRNA expression 4 h after IS or home cage (HC) control conditions in male rats, using in situ hybridization histochemistry...

Subclinical inflammation has been implicated in the development of depression, a common comorbidity of type 1 diabetes (T1D) and type 2 diabetes (T2D). This study aimed to characterise the relationships between biomarkers of inflammation and depressive symptoms in T1D and T2D. Biomarkers of inflammation were measured in serum of participants with elevated depressive symptoms and T1D (n = 389, mean age 38 years, diabetes duration 15 ± 11 years) or T2D (n = 204, mean age 56 years, diabetes duration 13 ± 8 years)...

OBJECTIVE: The aim of this study was to evaluate the effect of childhood trauma in cytokine serum levels of individuals with MDD. METHODS: This was a cross-sectional study population-based, with people aged 18 to 35. The Mini International Neuropsychiatric Interview (M.I.N.I) measured to current major depressive disorder (MDD). To evaluate traumatic experiences during childhood, the Childhood Trauma Questionnaire (CTQ) was applied. Serum TNF- α, IL-6 and IL-10 levels were measured by ELISA using a commercial kit...

Major depressive disorder (MDD) is one of the most common and debilitating neuropsychiatric illnesses. Accumulating evidence suggests a potential role of the immune system in the pathophysiology of MDD. The complement system represents one of the major effector mechanisms of the innate immune system, and plays a critical role in inflammation. However, the role of complement components in MDD is not well understood. Here, we found significant increase in component 3 (C3) expression in the prefrontal cortex (PFC) of depressed suicide subjects...

BACKGROUND: Depression is a widespread phenomenon with varying degrees of pathology in different patients. Various hypotheses have been proposed for the cause and continuance of depression. Some of these include, but not limited to, the monoamine hypothesis, the neuroendocrine hypothesis, and the more recent epigenetic and inflammatory hypotheses. OBJECTIVE: In this article, we review all the above hypotheses with a focus on the role of mitochondria as the connecting link...

BACKGROUND: Cardiovascular disease (CVD) and depression are extremely prevalent and debilitating conditions. Evidence suggests there is a two-way relationship between depression and CVD. Inflammation is implicated in the pathophysiology of both conditions, thus representing a central candidate mediating the link between these disorders. Depression is consistently associated with increased inflammation and increased blood levels of inflammatory molecules. In recent years, studies have shown that depression significantly increases the risk of developing inflammatory-related diseases such as CVD, precipitated by the same inflammatory pathways involved in the pathophysiology of CVD...

Chronic psychosocial stress at workplace is an important factor in the development of physical and mental illness. Objective biological measures of chronic stress are still lacking, but inflammatory response and growth factors are increasingly considered as potential stress biomarkers. Therefore, we investigated the relationship between psychophysical strain and serum levels of 48 chemokines, cytokines and growth factors measured using a multiplex immunoassay, and serum brain-derived neurotrophic factor (BDNF) measured by ELISA...

BACKGROUND: Previous systematic reviews indicate that progressive muscle relaxation (PMR) and guided imagery (GI) are both effective interventions to decrease the psychological impact and to alleviate the adverse events in cancer patients undergoing chemotherapy treatment. To date, no review studies have investigated the effectiveness of a combination of PMR and GI. AIM: To systematically review the current state of knowledge regarding the effects of the PMR-GI combination on cancer patients receiving chemotherapy...

High density lipoprotein (HDL) cholesterol levels and cholesterol efflux capacity (CEC) are inversely correlated with coronary artery disease (CAD) risk. Myeloperoxidase (MPO) derived oxidants and HDL proteome changes are implicated in HDL dysfunction in subjects with CAD in the United States; however, the effect of MPO on HDL function and HDL proteome in ethnic Chinese population is unknown. We recruited four matched ethnic Chinese groups (20 patients each): subjects with 1) low HDL levels (HDL levels in men <40mg/dL and women <50mg/dL) and non-CAD (identified by coronary angiography or cardiac CT angiography); 2) low HDL and CAD; 3) high HDL (men >50mg/dL; women >60mg/dL) with no CAD; and 4) high HDL with CAD...

BACKGROUND: Psychological distress is common among people with a substance abuse disorder in treatment. Identifying correlates of psychological distress may serve as points of intervention to improve substance abuse treatment outcomes. Immune function measured as cytokine levels have been associated with psychological distress, but this association remains unexplored among people with a substance abuse disorder in treatment. This study aimed to examine whether cytokine levels in patients treated for a substance use disorder were related to depression, anxiety, and overall psychological distress, and to observe these associations separately among people with a past year alcohol use disorder and those with a past year drug use disorder...

BACKGROUND: Studies of individual biomarkers for depression have shown insufficient sensitivity and specificity for clinical use, and most likely combinations of biomarkers may provide a better signature. The sorting-related receptor with A-type repeats (SorLA) is a well-studied pathogenic factor for Alzheimer's. SorLA belongs to the Vps10p domain receptor family, which also encompasses sortilin and SorCS1-3. All family members have been implicated in neurological and mental disorders...

Diabetes is associated with a high risk of developing cognitive dysfunction and neuropsychiatric disabilities, and these disease symptomsare termed diabetic encephalopathy (DEP). Inflammation is involved in the development of DEP. The cleavage and maturation of the proinflammatory cytokine interleukin (IL)-1β is regulated by the NLRP3 inflammasome. Obese and type 2 diabetic db/db mice show anxiety- and depression-like behaviors and cognitive disorders associated with hippocampal inflammation. The purpose of this study was to explore the role of NLRP3 inflammasome in DEP...

Depression and liver disease are closely associated. Every third patient with liver cirrhosis or hepatitis shows depressive symptoms. On the other hand, every third patient with depressive disorder develops an alcohol disorder at some point during his / her life. A crucial link between depression and hepatic disease seems to be inflammatory processes in which the microbiome and increased intestinal permeability of the intestine play a pivotal role. Depression as well as liver disease, alcohol consumption, stress, and aging processes disturb the delicate balance of intestinal microbiota resulting in increased intestinal permeability...
