High Mobility Group Box 1 Levels as an Inflammatory Mediator in Bipolar Mania.

Introduction: High mobility group box 1 protein (HMGB1) is a member of the molecular family known as damage-associated molecular patterns, which is implicated to have a role in neuroinflammation processes. In recent years, a growing number of studies have focused on the role of inflammation in Bipolar Disorder (BD). This study aimed to investigate the serum levels of HMGB1 and other inflammatory markers in patients with bipolar manic episodes compared to those in healthy controls (HC).

Eveningness chronotype influences social functioning by deteriorating depressive symptoms in remitted patients with schizophrenia.

Sleep and circadian rhythm disruption (SCRD) is common in schizophrenia patients, who also typically experience impaired social functioning. While various factors influence social functioning in schizophrenia, the specific impact of sleep and circadian rhythm disruption remains unclear. This study aimed to investigate the connection between chronotype and social functioning in remitted schizophrenia patients, examining the mediating roles of depression and sleep quality.

MAY PPAR GAMMA BE SIGNIFICANT IN BIPOLAR DISORDER ONLY IN THE PRESENCE OF METABOLIC SYNDROME?

They are confronted with uncertainties in their role descriptions and they witness illness, suffering and deaths as part of their everyday duties which may lead to burnout. Only several studies have focused on these experiences to find out what the family medicine residents and medical students were literally feeling.

Ten-Year Follow-Up of Earthquake Survivors: Long-Term Study on the Course of PTSD Following a Natural Disaster.

Few earthquake survivor studies extend follow-up beyond 2 years, leaving the long-term course of earthquake-related posttraumatic stress disorder (PTSD) unknown. This 10-year survey re-assessed the 1999 İzmit, Turkey, earthquake survivors. İzmit earthquake survivors (N = 198), previously assessed for PTSD/partial PTSD at 1-3 months and 18-20 months post-earthquake, were evaluated 10 years post-event from January 2009 through December 2010.

Detecting biomarkers associated with antipsychotic-induced extrapyramidal syndromes by using machine learning techniques.

Background: Antipsychotic-associated extrapyramidal syndromes (EPS) are a common side effect that may result in discontinuation of treatment. Although some clinical features of individuals who develop specific EPSs are well defined, no specific laboratory parameter has been identified to predict the risk of developing EPS.

Methods: Three hundred and ninety hospitalizations of patients under antipsychotic medication were evaluated.

Can the Imbalance between Neurotrophic and Apoptotic Proteins Be the "Beware the Ides of March" for Unaffected Relatives of Schizophrenia Patients?

Schizophrenia (SZ) is a mental disorder with a strong genetic basis as well as epigenetic aspects. Siblings of patients with SZ can share certain endophenotypes with the patients, suggesting that siblings may be important for distinguishing between trait and state markers. In the current study, we aimed to characterize the balance between pro-BDNF/mature BDNF and its receptors p75NTR/TrkB, which are tPA-BDNF pathways proteins and are thought to play a role in synaptic pruning, as a possible endophenotype of schizophrenia.

Serum nitric oxide levels are depleted in depressed patients treated with electroconvulsive therapy.

Background: Nitric oxide (NO) is an endogenous substance which has several endocrine functions and may act as neurotransmitter in the brain. High levels of NO may provoke nitrosative stress.

Aim: It was aimed to examine serum levels of NO in patients with depressive episodes who were treated with electroconvulsive therapy (ECT) in this study.

Can Neutrophil-Lymphocyte Ratio Be a Useful Criterion for Neuroleptic Malignant Syndrome in the Absence of Leukocytosis?

Neuroleptic malignant syndrome (NMS) is a rare but severe side effect of antipsychotic medication. Neutrophil-lymphocyte ratio (NLR) is a simple marker used to measure systemic inflammation. In this case report we explore the relationship of inflammation in the etiology of NMS.

A novel commentary: Investigation of the role of a balance between neurotrophic and apoptotic proteins in the pathogenesis of psychosis via the tPA-BDNF pathway.

Objective: Many hypotheses have put forward to better understand the pathogenesis of schizophrenia (SZ), such as synaptic pruning, stress-diathesis, neurodevelopment, neurodegeneration and neurotransmitter hypothesis; nonetheless, this pathogenesis still remains a mystery. The current study was designed with the hypothesis that impairment of a balance between pro-BDNF/mature BDNF and their receptors p75NTRK/TrkB may cause synaptic pruning in the pathogenesis of psychotic disorders.

Methods: Sixty-five drug-naïve patients with first-episode psychosis (FEP) who applied to outpatient clinics and were diagnosed according to DSM-5 as well as 65 healthy controls (HC) were included in the study.

Electroconvulsive Therapy and Extracellular Matrix Glycoproteins in Patients with Depressive Episodes.

Background: The brain extracellular matrix (ECM) is composed of glycoproteins deriving from the cell membrane and joining into nets called perineuronal nets (PNNs). The ECM glycoproteins limit neuroplasticity, cell proliferation, and differentiation. Electroconvulsive therapy (ECT) is provided by electrical currents that may alter several cascades and biophysical effects.

Resolvin D1 as a novel anti-inflammatory marker in manic, depressive and euthymic states of bipolar disorder.

Resolvin D1 (RvD1) is a soluble mediator, which is the metabolite of docosahexaenoic acid (DHA), an omega-3 fatty acid. It is thought that RvD1 may contribute to the etiology of bipolar disorder (BD) because of its anti-inflammatory and antidepressant effect. In this study, it was aimed to compare the serum RvD1 levels of patients with BD diagnosed manic-depressive-euthymic episodes with those of healthy subjects.

Clinical utility of neutrophil-lymphocyte ratio in the diagnosis of neuroleptic malignant syndrome.

Neuroleptic malignant syndrome (NMS) is a life-threatening side effect of antipsychotic medication. In this study, we aimed to investigate the hypothesis of inflammation neutrophil-lymphocyte ratio (NLR) in the etiology of NMS. In this retrospective case-control study, data were collected using digital database of Bakırköy Mental Health Research and Training State Hospital by screening NMS diagnosis according to 'International Classification of Diseases (ICD-10) code: between the years of 2007 and 2017.

Serum osmolarity and blood viscosity as a potential explanation for the pathophysiology of neuroleptic malignant syndrome.

Neuroleptic malignant syndrome (NMS) is a rare but life-threatening side effect. NMS patients usually develop dehydration and fluid-electrolyte imbalance. In this study, we aimed to investigate serum osmolarity and blood viscosity in patients with NMS.

Does Blood Flow Change according to Mood? Blood Rheology in Bipolar Disorder.

Objective: Bipolar disorder (BD) is associated with increased rates of cardiovascular diseases. There is growing evidence that blood viscosity may have a common role, correlated with well-known major risk factors that promote cardiovascular disease. In this study we aimed to investigate the whole blood viscosity (WBV) in different stages of BD.

Decreased circulating urokinase plasminogen activator receptor (uPAR) concentration in acute episodes of bipolar disorder; could it be a reflection of axonal injury?

Introduction: In recent years, the role of inflammation in the pathogenesis of Bipolar Disorder (BD) has been studied thoroughly. Urokinase-type plasminogen activator receptor (uPAR) is one of the molecules, whose concentration is of predictive value with regards to an ongoing inflammation and tissue regeneration, and it is hypothesized that it may also be altered in Bipolar Disorder. In this study, it is aimed to compare the levels of serum soluble uPAR during the manic, depressive and euthymic states of cases diagnosed with bipolar disorder, with healthy individuals.

Atherogenic index of plasma as a cardiovascular risk marker in manic, depressive, and euthymic stages of bipolar disorder.

Objective: Individuals with bipolar disorder (BD) frequently suffer from cardiovascular disease (CVD), and it is a leading cause of mortality. Clinicians use routine laboratory tests, including a lipid profile, to predict cardiovascular risk. In addition, a particular lipid ratio, the atherogenic index of plasma (AIP), is a sensitive, new parameter that can be used to assess highrisk groups.
