Abstract
AIM Bipolar disorder and major depressive disorder (MDD) have been demonstrated to be associated with proinflammatory states and cognitive function deficits. We aimed to investigate the differences of cognitive function and proinflammatory cytokines between patients with bipolar I disorder (BDI), bipolar II disorder (BDII), and MDD. METHODS Thirty-seven patients with BDI, 33 with BDII, 25 with MDD, and 54 age-, sex-matched controls were enrolled. All patients had a clinical global impression-severity scale ≤2. Serum levels of proinflammatory markers, including soluble interleukin-6 receptor, C-reactive protein, and soluble tumor necrosis factor receptor 1 (sTNF-αR1) were measured. Performance in the Word List Memory Task (WLMT), Wisconsin Card Sorting Task (WCST), 2-back task, Go/No-Go task, and divided attention task was assessed. RESULTS Patients with BDI had higher levels of sTNF-αR1 than patients with MDD and controls (P < 0.001). Patients with BDI performed worse on WLMT, WCST, 2-back task, divided attention_visual and divided attention_auditory tasks than the other three groups (all P < 0.05). Furthermore, sTNF-αR1 levels were negatively correlated with cognitive function measured using the WLMT and divided attention_auditory (all P < 0.05). CONCLUSIONS Patients with BDI had higher levels of sTNF-αR1 and cognitive function impairments than the remaining groups. Future studies are needed to explore the pathophysiology of sTNF-αR1 in the contribution of cognitive alterations.

The Impacts of Sun Exposure on Worker Physiology and Cognition: Multi-Country Evidence and Interventions. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:7698. [PMID: 34300148 PMCID: PMC8303297 DOI: 10.3390/ijerph18147698] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Revised: 07/12/2021] [Accepted: 07/14/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND A set of four case-control (n = 109), randomized-controlled (n = 7), cross-sectional (n = 78), and intervention (n = 47) studies was conducted across three countries to investigate the effects of sun exposure on worker physiology and cognition. METHODS Physiological, subjective, and cognitive performance data were collected from people working in ambient conditions characterized by the same thermal stress but different solar radiation levels. RESULTS People working under the sun were more likely to experience dizziness, weakness, and other symptoms of heat strain. These clinical impacts of sun exposure were not accompanied by changes in core body temperature but, instead, were linked with changes in skin temperature. Other physiological responses (heart rate, skin blood flow, and sweat rate) were also increased during sun exposure, while attention and vigilance were reduced by 45% and 67%, respectively, compared to exposure to a similar thermal stress without sunlight. Light-colored clothes reduced workers' skin temperature by 12-13% compared to darker-colored clothes. CONCLUSIONS Working under the sun worsens the physiological heat strain experienced and compromises cognitive function, even when the level of heat stress is thought to be the same as being in the shade. Wearing light-colored clothes can limit the physiological heat strain experienced by the body.

Neuropsychological characteristics of child and adolescent offspring of patients with bipolar disorder. Prog Neuropsychopharmacol Biol Psychiatry 2016; 65:54-9.

Abstract
BACKGROUND Bipolar disorder (BD) is a severe mental disorder with a strong genetic component. The assessment of child and adolescent offspring of patients diagnosed with BD (BDoff) provides an opportunity to investigate vulnerability factors and the first abnormalities associated with the disorder. Previous literature in child and adolescent BDoff is scarce and controversial. However, some studies concur in identifying significant impairment in executive functions, memory and attention. The present study aims to compare global neuropsychological characteristics of child and adolescent offspring of patients with bipolar disorder with a group of offspring of parentswith no history of psychotic disorder, and to assess the influence of psychopathology on neuropsychological performance. METHODS This research was part of The Bipolar and Schizophrenia Young Offspring Study (BASYS). A group of BDoff (N= 90) and a group of offspring of parents with no history of psychotic disorder (CC) (N = 107) were assessed with a complete neuropsychological battery. Intellectual quotient, working memory, processing speed, verbal memory and learning, visual memory, attention and executive functions were included in the cognitive assessment. RESULTS BDoff showed significantly worse performance in processing speed and immediate recall of visual memory relative to CC. When the presence of any lifetime psychopathology was analysed, the results showed that belonging to the BDoff group was the main explicative factor for the scores obtained in both processing speed and visual memory immediate recall, regardless of the presence of psychopathology. CONCLUSIONS These findings suggest that processing speed and visualmemory should be taken into consideration in future research on vulnerability markers of BD.

Tsitsipa E, Fountoulakis KN. The neurocognitive functioning in bipolar disorder: a systematic review of data. Ann Gen Psychiatry 2015; 14:42.

Abstract
BACKGROUND During the last decades, there have been many different opinions concerning the neurocognitive function in Bipolar disorder (BD). The aim of the current study was to perform a systematic review of the literature and to synthesize the data in a comprehensive picture of the neurocognitive dysfunction in BD. METHODS Papers were located with searches in PubMed/MEDLINE, through June 1st 2015. The review followed a modified version of the recommendations of the Preferred Items for Reporting of Systematic Reviews and Meta-Analyses statement. RESULTS The initial search returned 110,403 papers. After the deletion of duplicates, 11,771 papers remained for further evaluation. Eventually, 250 were included in the analysis. CONCLUSION The current review supports the presence of a neurocognitive deficit in BD, in almost all neurocognitive domains. This deficit is qualitative similar to that observed in schizophrenia but it is less severe. There are no differences between BD subtypes. Its origin is unclear. It seems it is an enduring component and represents a core primary characteristic of the illness, rather than being secondary to the mood state or medication. This core deficit is confounded (either increased or attenuated) by the disease phase, specific personal characteristics of the patients (age, gender, education, etc.), current symptomatology and its treatment (especially psychotic features) and long-term course and long-term exposure to medication, psychiatric and somatic comorbidity and alcohol and/or substance abuse.
