Though seemingly distinct and autonomous, emerging evidence suggests there is a bidirectional interaction between the intestinal microbiota and the brain. This crosstalk may play a substantial role in neurologic diseases, including anxiety, depression, autism, multiple sclerosis, Parkinson's disease, and, potentially, Alzheimer's disease. Long hypothesized by Metchnikoff and others well over 100 years ago, investigations into the mind-microbe axis is now seeing a rapid resurgence of research. If specific pathways and mechanisms of interaction are understood, it could have broad therapeutic potential, as the microbiome is environmentally acquired and can be modified to promote health...

Although sex differences in major depression have been reported repeatedly, the underlying mechanisms are still disputed. The rapidly changing gonadal steroid concentrations of the postpartum period or during menopause have been shown to be associated with depressive symptoms and to modulate the hypothalamic-pituitary-adrenal (HPA)-axis, which is implicated in depression. The sample comprised of 128 depressed in-patients (36.7% women) and 166 healthy controls (30.0% women). Blood was collected at baseline (at 6pm) and then 3 h as well as 21 h after ingestion of 1...

Sleep, a mysterious behavior, has recently been recognized as a crucial factor for health and longevity. The daily sleep/wake cycle provides the basis of biorhythms controlling whole-body homeostasis and homeodynamics; therefore, disruption of sleep causes several physical and psychological disorders, including cardiovascular disease, obesity, diabetes, cancer, anxiety, depression, and cognitive dysfunction. However, the mechanism linking sleep disturbances and sleep-related disorders remains unknown. Orexin (also known as hypocretin) is a neuropeptide produced in the hypothalamus...

Objectives: Many patients with hypothyroidism complain of persistent residual symptoms, despite optimal treatment, although the similar prevalence is seen in patients with documented absence of thyroid disorder in primary health-care setup. We aimed to investigate symptomatic relief in new cases of primary hypothyroidism and compare with controls with other chronic conditions. Methods: This prospective case-control follow-up study enrolled patients from July 2014 to May 2015 in an endocrine outpatient clinic of a tertiary hospital...

Background: The diagnosis of the disease, major depressive disorder (MDD), entirely depends on the presence of some symptoms without any biochemical parameter to support it. Depletion of dopamine though is an established feature, is not the sole causative factor of MDD. Moreover, it has very little diagnostic value due to a short half-life. Other chemical messengers like hormones have also been found to get altered due to significant over activity of hypothalamo-pituitary axis. Literature review suggests that cortisol, thyroid-stimulating hormone (TSH), and prolactin (PRL) are mostly altered in MDD, which can be utilized to diagnose the condition...

A number of factors (biogenic amine deficiency, genetic, environmental, immunologic, endocrine factors and neurogenesis) have been identified as mechanisms which provide unitary explanations for the pathophysiology of depression. Rather than a unitary construct, the combination and linkage of these factors have been implicated in the pathogenesis of depression. That is, environmental stressors and heritable genetic factors acting through immunologic and endocrine responses initiate structural and functional changes in many brain regions, resulting in dysfunctional neurogenesis and neurotransmission which then manifest as a constellation of symptoms which present as depression...

Although 2,2',4,4'-tetrabrominated diphenyl ether (BDE-47), 6-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (6-OH-BDE-47) and 6-methoxy-2,2',4,4'-tetrabromodiphenyl ether (6-MeO-BDE-47) clearly disrupt the endocrine system, current knowledge of their single and/or mixture toxicities on other behaviors of aquatic organisms remains limited. In the present study, Daphnia magna was used to investigate the single and mixture toxicities of BDE-47, 6-OH-BDE-47 and 6-MeO-BDE-47 as measured by inhibition of feeding during exposure and post-exposure periods...

Declining estradiol (E2), as occurs during menopause, increases risk for obesity and psychopathology (i.e., depression, anxiety). E2 modulates mood and energy homeostasis via binding to estrogen receptors (ER) in the brain. The often comorbid and bidirectional relationship between mood and metabolic disorders suggests shared hormonal and/or brain networks. The medial amygdala (MeA) is abundant in ERs and regulates mood, endocrine, and metabolic stress responses; therefore we tested the hypothesis that E2 in the MeA mitigates emotional and metabolic dysfunction in a rodent model of surgical menopause...

Ad libitum milk feeding and butyrate (B) supplementation have the potential to stimulate postnatal growth and development in calves. The somatotropic axis is the main endocrine regulator of postnatal growth and may be affected by both ad libitum milk replacer (MR) feeding and B supplementation in calves. We hypothesized that ad libitum MR feeding and B supplementation stimulate systemic and hepatic insulin-like growth factor (IGF)-I and IGF binding proteins (IGFBP) in preweaning calves. Sixty-four (32 male, 32 female) Holstein calves were examined from birth until wk 11 of life...

Sleep is essential for health. Slow wave sleep (SWS), the deepest sleep stage hallmarked by electroencephalographic slow oscillations (SOs), appears of particular relevance here. SWS is associated with a unique endocrine milieu comprising minimum cortisol and high aldosterone, growth hormone (GH), and prolactin levels, thereby presumably fostering efficient adaptive immune responses. Yet, whether SWS causes these changes is unclear. Here we enhance SOs in men by auditory closed-loop stimulation, i.e., by delivering tones in synchrony with endogenous SOs...

The gut microbiota is believed to affect a wide variety of mental disorders, including depression. The hypothesis involves bacterial signalling to the host through metabolic, endocrinal, immunologic and neuronal pathways. Few studies of patients with depression have shown altered microbiota profiles and increased levels of systemic endotoxin, which can be detected by leucocytes and result in expression of cytokines. Studies performed so far have lacked statistical power and provide no causal explanation for the gut-brain hypothesis...

Stressful life events are a major factor in the etiology of several diseases, such as cardiovascular, inflammatory and psychiatric disorders (i.e., depression and anxiety), with the two sexes greatly differing in vulnerability. In humans and other animals, physiological and behavioral responses to stress are strongly dependent on gender, and conditions that are stressful for males are not necessarily stressful for females. Hence the need of an animal model of social chronic stress specifically designed for females...

Memory functions can be considerably affected by various life events and stress has shown to be a chief regulator. Different stress patterns have distinct effects on the overall functioning of the brain. Stress provokes inflammation not only in the periphery but also in the brain. Neuroinflammation causes alterations in neuronal structure and function, which eventually progress to the development of neurodegenerative diseases. Inflammatory reactions are modulated through communication between the nervous, endocrine and immune systems...

The complex bidirectional communication between the gut and the brain is finely orchestrated by different systems, including the endocrine, immune, autonomic, and enteric nervous systems. Moreover, increasing evidence supports the role of the microbiome and microbiota-derived molecules in regulating such interactions; however, the mechanisms underpinning such effects are only beginning to be resolved. Microbiota-gut peptide interactions are poised to be of great significance in the regulation of gut-brain signaling...

BACKGROUND: Health-related quality of life (HRQOL) in multiple endocrine neoplasia type-1 (MEN-1) is poorly described. HRQOL in MEN-1 was compared with other chronic conditions and the US general population. METHODS: Adults aged ≥18 years recruited from an MEN-1 support group (n=153) completed the Patient-Reported Outcomes Measurement Information System (PROMIS) 29-item profile. MEN-1 scores were compared with PROMIS scores reported in peer-reviewed literature from back pain (n=218), cancer (n=310), congestive heart failure (CHF; n=60), chronic obstructive pulmonary disease (COPD; n=79), major depressive disorder (n=196), rheumatoid arthritis (RA; n=521), neuroendocrine tumors (NET; n=619), and primary hyperparathyroidism (PHPT; n=45) cohorts...

AIMS: Although associations between various somatic diseases and depression are well established, findings concerning the role of gender and anxiety disorders for these associations remain fragmented and partly inconsistent. Combining data from three large-scaled epidemiological studies in primary care, we aim to investigate interactions of somatic diseases with gender and anxiety disorders in the association with depression. METHODS: Self-reported depression according to the International Classification of Diseases, Tenth Edition (ICD-10) was assessed in n = 83 737 patients from three independent studies [DETECT (Diabetes Cardiovascular Risk Evaluation: Targets and Essential Data for Commitment of Treatment), Depression-2000 and Generalized Anxiety and Depression in Primary Care (GAD-P)] using the Depression Screening Questionnaire (DSQ)...
