Due to its multi-resistance and expression of various virulence factors, it is the causal agent of severe healthcare-acquired infections (HAIs). Effective strategies to control infections caused by must include early and specific detection of the pathogen for early and timely antibiotic prescription.

Is the acquired hypothyroidism a risk factor for developing psychiatric disorders?

Hypothyroidism is a prevalent thyroid condition in which the thyroid gland fails to secrete an adequate amount of thyroid hormone into the bloodstream. This condition may develop due to genetic or acquired factors. The most frequent cause of acquired hypothyroidism is chronic autoimmune thyroiditis, also known as Hashimoto's disease.

Effects of selective serotonin reuptake inhibitors on endocrine system (Review).

Selective serotonin reuptake inhibitors (SSRIs) are typically prescribed for treating major depressive disorder (MDD) due to their high efficacy. These drugs function by inhibiting the reuptake of serotonin [also termed 5-hydroxytryptamine (5-HT)], which raises the levels of 5-HT in the synaptic cleft, leading to prolonged activation of postsynaptic 5-HT receptors. Despite the therapeutic benefits of SSRIs, this mechanism of action also disturbs the neuroendocrine response.

Use of Extracellular Monomeric Ubiquitin as a Therapeutic Option for Major Depressive Disorder.

Major depressive disorder (MDD) is a mood disorder that has become a global health emergency according to the World Health Organization (WHO). It affects 280 million people worldwide and is a leading cause of disability and financial loss. Patients with MDD present immunoendocrine alterations like cortisol resistance and inflammation, which are associated with alterations in neurotransmitter metabolism.

S100 proteins: a new frontier in fibromyalgia research.

Fibromyalgia (FM) is a chronic condition that causes widespread pain, fatigue, and other symptoms that significantly affect quality of life. The underlying mechanisms of fibromyalgia involve both the immune system and the central nervous system. It has been proposed that changes in multiple ascending and descending pathways in the central nervous system may contribute to increased pain sensitivity in individuals with this condition.

Concomitant Treatment with Doxycycline and Rifampicin in Balb/c Mice Infected with 2308 Fails to Reduce Inflammation and Motor Disability.

Brucellosis is an infection widely distributed around the world, and in some countries it is considered a public health problem. Brucellosis causes insidious symptoms that make it difficult to diagnose. Infection can also trigger chronic pain and neuropsychiatric complications.

This work involved compiling marine cyanobacteria metabolites reported in the scientific literature that exhibit antiplasmodial activity.

Risperidone Decreases Expression of Serotonin Receptor-2A (5-HT2A) and Serotonin Transporter (SERT) but Not Dopamine Receptors and Dopamine Transporter (DAT) in PBMCs from Patients with Schizophrenia.

Dopamine and serotonin receptors and transporters play an essential role in the pathophysiology of schizophrenia; changes in their expression have been reported in neurons and leukocytes. Each antipsychotic induces a unique pattern in leukocyte function and phenotype. However, the use of polytherapy to treat schizophrenia makes it challenging to determine the specific effects of risperidone on peripheral blood mononuclear cells (PBMCs).

Upregulation of S100A8 in peripheral blood mononuclear cells from patients with depression treated with SSRIs: a pilot study.

Background: Major depressive disorder (MDD) affects more than 350 million people worldwide, and there is currently no laboratory test to diagnose it. This pilot study aimed to identify potential biomarkers in peripheral blood mononuclear cells (PBMCs) from MDD patients.

Methods: We used tandem mass tagging coupled to synchronous precursor selection (mass spectrometry) to obtain the differential proteomic profile from a pool of PBMCs from MDD patients and healthy subjects, and quantitative PCR to assess gene expression of differentially expressed proteins (DEPs) of our interest.

Modulation of vagal activity may help reduce neurodevelopmental damage in the offspring of mothers with pre-eclampsia.

Maternal Immune Activation (MIA) has been linked to the pathogenesis of pre-eclampsia and adverse neurodevelopmental outcomes in the offspring, such as cognitive deficits, behavioral abnormalities, and mental disorders. Pre-eclampsia is associated with an activation of the immune system characterized by persistently elevated levels of proinflammatory cytokines, as well as a decrease in immunoregulatory factors. The Cholinergic Anti-inflammatory Pathway (CAP) may play a relevant role in regulating the maternal inflammatory response during pre-eclampsia and protecting the developing fetus from inflammation-induced damage.

Imipramine Administration in -Infected Mice Restores Hippocampal Serotonin Levels, Muscle Strength, and Mood, and Decreases Spleen CFU Count.

Brucellosis infection causes non-specific symptoms such as fever, chills, sweating, headaches, myalgia, arthralgia, anorexia, fatigue, and mood disorders. In mouse models, it has been associated with increased levels of IL-6, TNF-α, and IFN-γ, a decrease in serotonin and dopamine levels within the hippocampus, induced loss of muscle strength and equilibrium, and increased anxiety and hopelessness. Imipramine (ImiP), a tricyclic antidepressant, is used to alleviate neuropathic pain.

Therapeutic treatment with fluoxetine using the chronic unpredictable stress model induces changes in neurotransmitters and circulating miRNAs in extracellular vesicles.

The most widely prescribed antidepressant, fluoxetine (FLX), is known for its antioxidant and anti-inflammatory effects when administered post-stress. Few studies have evaluated the effects of FLX treatment when chronic stress has induced deleterious effects in patients. Our objective was to evaluate FLX treatment (20 mg/kg/day, i.

Altered neutrophil-to-lymphocyte ratio in sepsis secondary to canine parvoviral enteritis treated with and without an immunomodulator in puppies.

Neutrophil-to-lymphocyte ratio (NLR) is a cheap and easy-to-obtain biomarker that mirrors the balance between innate and adaptive immunity. Cortisol and catecholamines have been identified as major drivers of NLR. High cortisol levels increase neutrophils while simultaneously decreasing lymphocyte counts.

Vortioxetine treatment decreases cocaine-induced locomotor sensitization in rats.

Vortioxetine is a serotoninergic multi-target antidepressant, approved to treat major depressive disorder, and carries out its behavioral, pharmacological, and physiological effects through the blocking of serotonin 5-HT, 5-HT, and 5-HT receptors and by activating 5-HT receptors. Some studies report that the simultaneous activation of the 5-HT serotonin receptors or blockade of 5-HT serotonin receptors decreased cocaine-induced locomotor activity and cocaine self-administration. Recent studies showed that vortioxetine decreased alcohol consumption.

Agomelatine decreases cocaine-induced locomotor sensitisation and dopamine release in rats.

Background: Agomelatine is a melatoninergic antidepressant approved to treat the major depressive disorder. Agomelatine exerts its behavioural, pharmacological, and physiological effects through the activation of MT and MT melatonin receptors and the blockade of 5-HT and 5-HT serotonin receptors. Some studies have reported that the activation of the MT and MT melatonin receptors decreased cocaine-induced locomotor activity and cocaine self-administration.

Screening of SERT and p11 mRNA Levels in Airline Pilots: A Translational Approach.

Airline pilots are frequently exposed to numerous flights per week, changes in their circadian rhythms, and extended periods away from home. All these stressors make pilots susceptible to developing psychiatric disorders. Recently, emphasis has been placed on the need for molecular tests that help in the diagnosis of depression.

NeuroImmunoEndocrinology: A brief historic narrative.

Although no precise moment or unique event marks its birth, neuroimmunoendocrinology arguably shares a great deal of history with other medical and biologic disciplines. It originated from empirical observations and suppositions that failed to prevail upon the existing axioms. Despite the widespread resistance to embracing novel ideas, the seeming defeats inspired visionary researchers.

Increased survival in puppies affected by Canine Parvovirus type II using an immunomodulator as a therapeutic aid.

Canine parvovirus type II (CPV-2) infection induces canine parvoviral enteritis (CPE), which in turn promotes sepsis and systemic inflammatory response syndrome (SIRS). Mortality in this disease is usually registered within 48-72 h post-hospitalization, the critical period of the illness. It has been recently described that the use of an immunomodulator, whose major component is monomeric ubiquitin (mUb) without the last two glycine residues (Ub∆GG), in pediatric human patients with sepsis augments survival.

Behavioral and Neurochemical Shifts at the Hippocampus and Frontal Cortex Are Associated to Peripheral Inflammation in Balb/c Mice Infected with .

Brucellosis is a zoonosis affecting 50,000,000 people annually. Most patients progress to a chronic phase of the disease in which neuropsychiatric symptoms upsurge. The biological processes underlying the progression of these symptoms are yet unclear.

Experimental Pulmonary Tuberculosis in the Absence of Detectable Brain Infection Induces Neuroinflammation and Behavioural Abnormalities in Male BALB/c Mice.

Tuberculosis (TB) is a chronic infectious disease in which prolonged, non-resolutive inflammation of the lung may lead to metabolic and neuroendocrine dysfunction. Previous studies have reported that individuals coursing pulmonary TB experience cognitive or behavioural changes; however, the pathogenic substrate of such manifestations have remained unknown. Here, using a mouse model of progressive pulmonary TB, we report that, even in the absence of brain infection, TB is associated with marked increased synthesis of both inflammatory and anti-inflammatory cytokines in discrete brain areas such as the hypothalamus, the hippocampal formation and cerebellum accompanied by substantial changes in the synthesis of neurotransmitters.

Melatonin decreases cocaine-induced locomotor sensitization and cocaine-conditioned place preference in rats.

Melatonin is a hormone that produces behavioral, pharmacological, and physiological effects through the activation of MT1 and MT2 melatonin receptors. Melatonin receptors participate in the modulation of the reinforcing effects of cocaine. Some studies report that dosing of melatonin decreases cocaine-induced locomotor activity and cocaine self-administration and that luzindole, an MT1, and MT2 melatonin receptor antagonist, blocks the melatonin-dependent decrease in cocaine-induced locomotor activity.
