Shape analysis of the cingulum, uncinate and arcuate fasciculi in patients with bipolar disorder
2016
Background: Abnormal maturation of brain connectivity is supposed to underlie the dysfunctional emotion regulation in patients with bipolar disorder (BD). To test this hypothesis, white matter integrity is usually investigated using measures of water diffusivity provided by MRI. Here we consider a more intuitive aspect of the morphometry of the white matter tracts: the shape of the fibre bundles, which is associated with neurodevelopment. We analyzed the shape of 3 tracts involved in BD: the cingulum (CG), uncinate fasciculus (UF) and arcuate fasciculus (AF). Methods: We analyzed diffusion MRI data in patients with BD and healthy controls. The fibre bundles were reconstructed using Q-ball–b…
Clinical staging and serum cytokines in bipolar patients during euthymia
2017
Aims: Changes in serum cytokines and altered neutrophin concentration have been associated with bipolar disorder (BD). Our aim here was to analyze peripheral blood biomarkers according to the clinical stages of BD. Method: Euthymic BD-I patients were grouped according to their level of functioning in early-stage (n = 25) and late-stage (n = 23), and compared to healthy siblings (n = 23) and genetically unrelated healthy controls (n = 21). Neurotrophin (neurotrophin-3 and BDNF) concentration and biomarkers of inflammation, including cytokines (IL-6, IL-10 and TNF-alpha), leukocytes count and acute phase proteins, were measured. Results: IL-10 concentration was significantly increased in earl…
Gender differences in C-reactive protein and homocysteine modulation of cognitive performance and real-world functioning in bipolar disorder.
2018
Background: Cognitive and psychosocial impairment has been associated with increased levels of C-reactive protein (CRP) and homocysteine in bipolar disorder, but gender differences have seldom been studied. Methods: Two hundred and twenty-four bipolar outpatients were included. Cognitive performance was assessed through the Screen for Cognitive Impairment in Psychiatry (SCIP). Psychosocial functioning was evaluated using the Functioning Assessment Short Test (FAST) and the General Assessment of Functioning (GAF). Homocysteine and CRP levels were determined. Separate analyses were performed by gender. Partial correlations were calculated to test for associations between biomarkers and cognit…
Do affective episodes modulate moral judgment in individuals with bipolar disorder?
2018
Abstract Background Bipolar disorder (BD) patients experience altered emotional states and deficits in social adaptation that may also be involved in deontological moral judgments in which participants have to choose whether to sacrifice one person in order to save the lives of a greater number. Methods In the present study we compared the utilitarian responses of BD patients in their different states (euthymia, mania, depression) and healthy controls to moral dilemmas with low (impersonal dilemma) and high (personal dilemma) emotional saliency. Results Our findings revealed an increased tendency to utilitarian judgments in the three groups of BD patients in impersonal dilemmas relative to …
Factors associated with poor functional outcome in bipolar disorder: sociodemographic, clinical, and neurocognitive variables.
2018
Objective: The current investigation aimed at studying the sociodemographic, clinical, and neuropsychological variables related to functional outcome in a sample of euthymic patients with bipolar disorder(BD) presenting moderate-severe levels of functional impairment. Methods: Two-hundred and thirty-nine participants with BD disorders and with Functioning Assessment Short Test(FAST) scores equal or above 18 were administered a clinical and diagnostic interview, and the administration of mood measure scales and a comprehensive neuropsychological battery. Analyses involved preliminary Pearson bivariate correlations to identify sociodemographic and clinical variables associated with the FAST t…
The association between depression symptoms, psychological burden caused by Covid-19 and physical activity: An investigation in Germany, Italy, Russi…
2020
Highlights • Depression symptoms are positively linked to burden by Covid-19. • Physical activity can buffer the impact of depression on the burden experience. • Physical activity is a protective factor against negative Covid-19 consequences. • Same result pattern in Germany, Italy, Russia and Spain.
The relationship of personality traits to substance abuse in patients with bipolar disorder
2007
AbstractPurposeThe aim of this study is to determine if personality traits contribute to the likelihood of substance abuse in Bipolar Disorder (BD).Subjects/materials and methodsFifty-nine patients meeting DSM-IV criteria for BD: 20 without any history of Substance Related Disorder (SRD), 21 with a lifetime history of SRD but without current SRD, and 18 with current SRD. Patients filled out the TCI, the differences were analyzed by ANOVA and the likelihood was obtained by Multinomial Logistic Regression.ResultsOnly Novelty Seeking (NS) is statistically different between the groups. Patients with BD with current SRD have higher rates in NS than those with past SRD, and those without a histor…
Failure to find association between childhood abuse and cognition in first-episode psychosis patients
2012
AbstractThis study investigated the relationship between severe childhood abuse and cognitive functions in first-episode psychosis patients and geographically-matched controls. Reports of any abuse were associated with lower scores in the executive function domain in the control group. However, in contrast with our hypothesis, no relationships were found amongst cases.
Systematic Review on Post-Traumatic Stress Disorder Among Survivors of the Wenchuan Earthquake
2016
Post-traumatic stress disorder (PTSD) widely occurs among victims or witness of disasters. With flashbacks, hyperarousal, and avoidance being the typical symptoms, PTSD became a focus of psychological research. The earthquake in Wenchuan, China, on May 12, 2008, was without precedent in magnitude and aftermath and caused huge damage, which drew scientists’ attention to mental health of the survivors. We conducted a systematic overview by collecting published articles from the PubMed database and classifying them into five points: epidemiology, neuropathology, biochemistry, genetics and epigenetics, and treatment. The large body of research during the past 6 years showed that adolescents an…
The effects of job satisfaction and psychological resilience on job performance among residents of the standardized residency training: a nationwide …
2020
High resident job performance is essential for effective medical professionalism. To date, few studies have investigated the potential predictors of job performance among residents in standardized residency training (SRT) program in China. Therefore, a nationwide survey among Chinese residents in SRT program was conducted to evaluate the impact of job satisfaction and psychological resilience on job performance. A total of 1146 residents from 9 hospitals were recruited in this study. Demographic and work-related information, job satisfaction, psychological resilience and job performance were collected through questionnaires. Hierarchical regression analyses indicated that, "work pressure", …
