coenzyme-q10 and Bipolar-Disorder

Bipolar disorder (BPD) is a chronic and recurrent mood disorder characterized by episodes of mania, hypomania, and major depression. Based on available evidence, mitochondrial dysfunction, oxidative stress, and inflammation have important roles in the pathophysiology of bipolar depression. More specifically, it seems that coenzyme Q10 (CoQ10), a mitochondrial modulator, as well as an antioxidant and anti-inflammatory agent, might be effective in modulating these pathophysiological pathways. Accordingly, the aim of this study was to investigate whether and to what extent, compared with placebo, adjuvant CoQ10 might improve symptoms of depression in patients with BPD.. A total of 69 patients with BPD with a current depressive episode were randomly assigned either to the adjuvant CoQ10 (200 mg/d) or to the placebo group. Standard medication consisting of mood stabilizers and antidepressants was consistent 2 months prior and during the study. Depression severity for each patient was assessed based on the Montgomery-Asberg Depression Rating Scale scores at baseline, fourth week, and eighth week of the study.. Symptoms of depression decreased over time in both groups. Compared with the placebo group, adjuvant CoQ10 to a standard medication improved symptoms of depression after 8 weeks of treatment. In addition, at the end of the study, it turned out that more responders were observed in the CoQ10 group, compared with the placebo group. CoQ10 had minimal adverse effects and was well tolerated.. The present pattern of results suggests that among patients with BPD, compared with placebo, adjuvant CoQ10 probably because of its antioxidant and anti-inflammatory properties can improve symptoms of depression over a period of 8 weeks.

Im Rahmen der vorliegenden Studie sollte der Einfluss des Weichteilschadens auf das klinische Ergebnis nach offener Ellenbogenluxation untersucht werden.. Von Oktober 2008 bis August 2015 wurden insgesamt 230 Patienten mit Ellenbogenluxation behandelt. Diese retrospektive Studie umfasst 21 Fälle von offenen Ellenbogenluxationen. Das Durchschnittsalter der Patienten betrug 49 Jahre alt (20–83 Jahre), 6 Patienten waren weiblich (29%), 15 männlich (71%). Das Bewegungsausmaß des verletzten und unverletzten Ellenbogens wurde erhoben und das funktionelle Ergebnis u. a. mittels Mayo Elbow Performance Score (MEPS), Mayo Wrist Score (MWS) und dem Disability of Arm, Shoulder and Hand (DASH) Score erfasst. Zusätzlich wurden Komplikationen und Revisionsoperationen aufgezeichnet. Der Einfluss des Weichteilschadens (I°/II° offen vs. III° offen) und des Luxationstyps (einfach vs. komplex) auf das klinische Ergebnis wurde analysiert.. Offene Ellenbogenluxationen können mit einem zufriedenstellenden klinischen Ergebnis einhergehen. Insbesondere komplexe offene Ellenbogenluxationen sind jedoch sehr komplikationsbehaftet, wobei neurovaskuläre Komplikationen am häufigsten auftreten.. The current high rate of multidrug-resistant gram-negative bacteria infections among hospitalised patients with cUTIs in the studied area is alarming. Our predictive model could be useful to avoid inappropriate antibiotic treatment and implement antibiotic stewardship policies that enhance the use of carbapenem-sparing regimens in patients at low risk of multidrug-resistance.. The results indicated differential patterns of Inhibition of Return between the High and Low shape/weight based self-worth groups. The High group displayed increased inhibition of return for the shape/weight stimuli relative to control stimuli, while the Low group displayed reduced inhibition of return for the shape/weight stimuli compared to control stimuli. The ED group displayed a similar pattern of results to the High group, but this did not reach significance.. The current findings indicate that young women without an eating disorder who base their self-worth on shape/weight display a pattern of avoidance of shape/weight stimuli that is in direct contrast to those at low risk of developing eating disorders. The possible implications of these specific patterns of inhibition of return across those at varying levels of risk for an eating disorder are discussed along with their implications for intervention approaches.. These results indicated that Sr. An unusually high HbA

Despite the prevalence, associated comorbidities, and functional consequences of bipolar depression (BPD), underlying disease mechanisms remain unclear. Published studies of individuals with bipolar disorder implicate abnormalities in cellular energy metabolism. This study tests the hypotheses that the forward rate constant (k(for)) of creatine kinase (CK) is altered in older adults with BPD and that CoEnzyme Q10 (CoQ10), known to have properties that enhance mitochondrial function, increases k(for) in elderly individuals with BPD treated with CoQ10 compared with untreated age- and sex-matched controls.. Ten older adults (ages 55 and above) with Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition [DSM IV]) bipolar disorder, current episode depressed and 8 older controls underwent two 4 Tesla (31)Phosphorus magnetic resonance spectroscopy ((31)PMRS) scans 8 weeks apart using a magnetization transfer (MT) acquisition scheme to calculate k(for). The BPD group was treated with open-label CoEnzyme Q10 400 mg/d titrated up by 400 mg/d every 2 weeks to a maximum of 1200 mg/d. The Montgomery Asberg Depression Rating Scale (MADRS) was used to measure depression symptom severity. Baseline k(for) and changes in k(for) were compared between individuals with BPD and controls, not receiving CoQ. Clinical ratings were compared across time and associated with k(for) changes using repeated measures linear regression.. The k(for) of CK was nonsignificantly lower for BPD than healthy controls at baseline (BPD mean (standard deviation [SD]) = 0.19 (0.02), control mean (SD) = 0.20 (0.02), Wilcoxon rank sum exact P = .40). The k(for) for both CoQ10-treated BPD and controls increased after 8 weeks (mean increase (SD) = 0.03 (0.04), Wilcoxon signed rank exact P = .01), with no significant difference in 8-week changes between groups (BPD mean change (SD) = 0.03 (0.03), control mean change (SD) = 0.03 (0.05), Wilcoxon rank sum exact P = .91). In an exploratory analysis, depression severity decreased with CoQ10 treatment in the group with BPD (F (3,7) = 4.87, P = .04) with significant reductions in the MADRS at weeks 2 (t (9) = -2.40, P = .04) and 4 (t (9) = -3.80, P = .004).. This study employing the novel MRS technique of MT did not demonstrate significance between group differences in the k(for) of CK but did observe a trend that would require confirmation in a larger study. An exploratory analysis suggested a reduction in depression symptom severity during treatment with high-dose CoEnzyme Q10 for older adults with BPD. Further studies exploring alterations of high-energy phosphate metabolites in geriatric BPD and efficacy studies of CoQ10 in a randomized controlled trial are both warranted.

Most suicidality literature in Huntington disease (HD) is based on natural history studies or retrospective reviews, but reports on risk factors from clinical trials are limited.. We analyzed 609 participants from 2CARE, a randomized, double-blind, placebo-controlled clinical trial with up to 5 years of follow-up, for risk factors related to suicidality. The primary outcome variable was the time from randomization until the first occurrence of either suicidal ideation or attempt. We also considered time from randomization until the first suicide attempt as a secondary outcome variable.. These data suggest psychiatric comorbidities in HD are predictive of suicidal behavior while participating in clinical trials, reinforcing the importance of clinical surveillance and treatment towards lessening risk during participation and perhaps beyond. Designing a composite algorithm for early prediction of suicide attempts in HD may be of value, particularly given anticipated trials aimed at disease modification are likely to be long-term..

Bipolar disorder (BPD) is a severe and chronic mental disease with high rates of social and functional disability. To explain the emergence and maintenance of BPD, increasing attention has been focused on dimensions of inflammation and oxidative stress (OTS). Coenzyme Q10 (CoQ10) is known for its anti-oxidant and anti-inflammatory effects; accordingly, the aim of the present study was to investigate, if compared to placebo, adjuvant CoQ10 might favorably impact on serum levels of inflammatory and OTS biomarkers in patients with BPD during their depressive phase. A total of 89 BPD patients, currently in a depressive episode were allocated by block randomization either to the adjuvant CoQ10 (200 mg/day) condition or to the placebo condition. At baseline and 8 weeks later at the end of the study, serum levels of total antioxidant capacity (TAC), total thiol groups (TTG), catalase activity (CAT), nitric oxide (NO), malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α), interlukin-6 (IL-6), and IL-10 were assessed. 69 patients completed the 8-week lasting study. Compared to baseline and to the placebo condition, serum levels of TTG and TAC significantly increased, and TNF-α, IL-10, and NO statistically decreased over time in the adjuvant CoQ10 condition. No statistically significant changes were observed for CAT, MDA, and IL-6. The pattern of results suggests that compared to placebo and over a time lapse of 8 weeks, adjuvant CoQ10 favorably impacted on OTS and inflammatory biomarkers in patients with BPD during the depressive episode. Thus, CoQ10 might be considered a safe and effective strategy for treatment of patients with BPD during their depressive phase.
