BACKGROUND: Postoperative delayed paradoxical depression (PDPD) is a psychiatric condition described in patients who undergo a major surgery without complications, do not have a history of mood disorders, but nevertheless become clinically depressed. PDPD has been recognized in major surgical interventions such as coronary artery bypass surgery. We sought to determine the incidence and potential factors associated with PDPD after surgical treatment of intracranial aneurysms. METHODS: The cohort of 105 patients was derived from a prospective observational dataset of 3788 consecutive cases of intracranial aneurysms accrued from 1991-2015...

Multiple lines of evidence suggest the hypothesis that high dose thyroid therapy corrects for cellular hypothyroidism found in bipolar disorders. Evidence indicates that bipolar disorders are associated with mitochondrial dysfunction which results in low cellular adenosine 5'-triphosphate (ATP) levels. Transport of thyroid hormones into cells is energy intensive and dependent on ATP except in the pituitary gland. Inadequate ATP levels makes it difficult to get thyroid hormone into cells leading to cellular hypothyroidism...

OBJECTIVE: rs12576775 was found to be associated with bipolar disorder (BD) in a genome-wide association study (GWAS). The GWAS signal implicates genes for the microRNAs miR-708 and miR-5579 and the first exon of the Odd Oz/ten-m homolog 4 gene (ODZ4). In the present study, miR-708, its surrounding region, and its targets were analyzed for potential BD-associated functional variants. METHODS: The miR-708 gene and surrounding regions were screened for variation using high-resolution melting (HRM) analysis in 1099 cases of BD, followed by genotyping of rare variants in an enlarged sample of 2078 subjects with BD, 1303 subjects with schizophrenia, and 1355 healthy controls...

Several aspects of meiosis are impacted by the absence of centrosomes in oocytes. Here, we review four aspects of meiosis I that are significantly affected by the absence of centrosomes in oocyte spindles. One, microtubules tend to assemble around the chromosomes. Two, the organization of these microtubules into a bipolar spindle is directed by the chromosomes. Three, chromosome bi-orientation and attachment to microtubules from the correct pole require modification of the mechanisms used in mitotic cells. Four, chromosome movement to the poles at anaphase cannot rely on polar anchoring of spindle microtubules by centrosomes...

BACKGROUND: Excessive alcohol use is associated with brain damage but less is known about brain effects from moderate alcohol use. Previous findings indicate that patients with severe mental illness, particularly schizophrenia, are vulnerable to alcohol-related brain damage. We investigated the association between levels of alcohol consumption and cortical and subcortical brain structures in schizophrenia and bipolar disorder patients and healthy controls, and investigated for group differences for this association...

BACKGROUND: Emotional intelligence is our capacity to acknowledge our own emotions, and the emotions of other people; it also has to do with the way emotions must be understood, and used productively. Given that an altered state of mind can have an impact on emotional intelligence, our objective was to correlate the psychological state with emotional intelligence in residents of gynecology, and obstetrics. METHODS: We assessed 76 gynecology and obstetrics residents by using What's my M3 and TMMS-24 instruments, in order to know the influence of psychological state on emotional intelligence...

INTRODUCTION: Bipolar disorder (BD) is considered to have a better outcome in comparison to schizophrenia. However, recent data dispute this notion. The current study aimed to compare the burden of patients with BD type I (BD-I) in remission with similar patients with schizophrenia (SZ) in remission. MATERIALS AND METHODS: Patients with schizophrenia (n=75) and BD-I (n=54) aged 18-64years were included in the study. The diagnosis was made with the SCID-I/P. Patients were assessed for sociodemographic variables, stigma, quality of life, disability, suicidality and current symptomatology...

OBJECTIVES: Disturbances in sleep and waking patterns are highly prevalent during mood episodes in bipolar disorder. The question remains whether these disturbances persist during phases of euthymia and whether they are heritable traits of bipolar disorder. The current study investigates objective sleep measures in a large sample of bipolar I patients, non-affected siblings and controls. METHODS: A total of 107 bipolar disorder I patients, 74 non-affected siblings, and 80 controls were included...

Recent work using a mouse model has identified the glutamate metabotropic receptor 7 (Grm7) gene as a strong candidate gene for alcohol consumption. Although there has been some work examining the effect of human glutamate metabotropic receptor 7 (GRM7) polymorphisms on human substance use disorders, the majority of the work has focused on other psychiatric disorders such as ADHD, major depressive disorder, schizophrenia, bipolar disorder, panic disorder, and autism spectrum disorders. The current study aimed to evaluate evidence for association between GRM7 and alcohol behaviors in humans using a single nucleotide polymorphism (SNP) approach, as well as a gene-based approach...

Neuropsychiatric diseases, such as bipolar disorder (BD) and schizophrenia (SCZ), have a very complex pathophysiology. Several current studies describe an association between psychiatric illness and mitochondrial dysfunction and consequent cellular modifications, including lipid, protein, and DNA damage, caused by cellular oxidative stress. Euterpe oleracea (açaí) is a powerful antioxidant fruit. Açaí is an Amazonian palm fruit primarily found in the lowlands of the Amazonian rainforest, particularly in the floodplains of the Amazon River...

Childhood adverse events are risk factors for later bipolar disorder. We quantified the risks for a later diagnosis of bipolar disorder after exposure to adverse life events in children with and without parental psychopathology. This register-based population cohort study included all persons born in Denmark from 1980 to 1998 (980 554 persons). Adversities before age 15 years were: familial disruption; parental somatic illness; any parental psychopathology; parental labour market exclusion; parental imprisonment; placement in out-of-home care; and parental natural and unnatural death...

Many women with bipolar disorder experience significant morbidity during pregnancy and the postpartum period. The use of evidence-based and up-to-date guidelines has the potential to improve maternal and neonatal care. We review the latest clinical practice guidelines to gather recommendations for the peripartum management of bipolar disorder. Areas covered: Three electronic databases, MEDLINE/PubMed, the Cochrane Library, and the National Guidelines Clearinghouse were searched using various combinations of the following terms: bipolar disorder, pregnancy, postpartum, peripartum, puerperal, antenatal, postnatal, and guidelines...

BACKGROUND: Cardiac resynchronization therapy (CRT) was shown to improve heart failure (HF) prognosis. But many patients do not benefit from CRT. Optimization of left ventricular (LV) lead position to the latest activated LV area is important to increase CRT response. We aimed to detect the relationship between LV lead sensing delay and echocardiographic and electrocardiographic response to CRT treatment. METHODS: We prospectively included 156 consecutive patients with HF diagnosis, QRS ≥ 120 ms, left bundle branch block, New York Heart Association II-IV, LV ejection fraction (LVEF) < 35%, and scheduled for CRT (100 male, 56 female; mean age 65...

INTRODUCTION: Cannabis use is very frequent in bipolar disorder and has been found to increase the duration and frequency of manic symptoms while decreasing those of depression. Bipolar patients who use cannabis were shown to have poorer compliance to treatment, more symptoms that are psychotic and a worse prognosis than patients who do not. In this study, we have evaluated the importance of cannabis use among bipolar patients admitted to the Psychiatric Hospital of the Cross, Lebanon (Hôpital Psychiatrique de la Croix [HPC]) as well as the clinical differences between cannabis users and non-users...

Bipolar disorder is a chronic and disabling mood disorder with a complex pathophysiological basis. A significant percentage of patients do not receive correct diagnosis which directly influences therapeutic response, rendering recovery troublesome. There is a long-standing need for proper non-clinically based tools for diagnosis, treatment selection and follow-up of such patients. Areas covered: In the past decade, the scientific community has shown a great interest in biomarker development. Here, we highlight the different potential biomarkers and we discuss their feasibility and their possible clinical relevance...

BACKGROUND: Bipolar disorder (BD) mania patients exhibit poor cognition and reward-seeking/hypermotivation, negatively impacting a patient's quality of life. Current treatments (e.g., lithium), do not treat such deficits. Treatment development has been limited due to a poor understanding of the neural mechanisms underlying these behaviors. Here, we investigated putative mechanisms underlying cognition and reward-seeking/motivational changes relevant to BD mania patients using two validated mouse models and neurochemical analyses...

Hyperactivity is a core symptom in various psychiatric disorders, including attention-deficit/hyperactivity disorder, schizophrenia, bipolar disorders, and anorexia nervosa. Although hyperactivity has been linked to dopaminergic signalling, the causal relationship between midbrain dopamine neuronal activity and locomotor hyperactivity remains unknown. In this study, we test whether increased dopamine neuronal activity is sufficient to induce locomotor hyperactivity. To do so, we used designer receptors exclusively activated by designer drugs (DREADD) to chemogenetically enhance neuronal activity in two main midbrain dopamine neuron populations, i...

BD-II has been consistently associated with cognitive dysfunction across a broad range of cognitive domains. Atypical antipsychotic drugs, or SGAs are effective antipsychotics in these diseases, often in combination with antidepressants and mood stabilizers. Data on the possible effect of antipsychotics on neuro-cognition are rare and conflicting. The main objective of our study was to assess the effectiveness and possible risks to cognitive function in a group of inpatients affected by BD-II. Forty-five inpatients with Bipolar II Disorder (DSM-5) were included in a two-year observational study...
