OBJECTIVE The risk-benefit profile of antidepressant medications in bipolar disorder is controversial. When conclusive evidence is lacking, expert consensus can guide treatment decisions. The International Society for Bipolar Disorders (ISBD) convened a task force to seek consensus recommendations on the use of antidepressants in bipolar disorders. METHOD(More)
CONTEXT Findings that protein kinase C (PKC) activity may be altered in mania, and that both lithium carbonate and valproate sodium inhibit PKC-associated signaling in brain tissue, encourage development of PKC inhibitors as candidate antimanic agents. OBJECTIVE To perform a controlled test of antimanic efficacy of the centrally active PKC inhibitor(More)
We conducted meta-analyses of findings from randomized, placebo-controlled, short-term trials for acute mania in manic or mixed states of DSM (III-IV) bipolar I disorder in 56 drug-placebo comparisons of 17 agents from 38 studies involving 10,800 patients. Of drugs tested, 13 (76%) were more effective than placebo: aripiprazole, asenapine, carbamazepine,(More)
STUDY OBJECTIVE To evaluate the effect of the neuromuscular blocking agent, rocuronium, on clinical recovery from electroconvulsive therapy (ECT) as compared with succinylcholine. DESIGN Cross-over study. SETTING University hospital. PATIENTS 13 ASA physical status I and II patients, ages 18 to 60 years, receiving ECT three times a week. (More)
Early onset in bipolar disorder (BPD) has been associated with greater familial risk and unfavorable clinical outcomes. We pooled data from seven international centers to analyze the relationships of family history and symptomatic as well as functional measures of adult morbidity to onset age, or onset in childhood (age <12), adolescence (12-18), or(More)
ETS domain transcription factor Elk-1 has been primarily studied in the regulation of genes in response to mitogenic stimuli, however the presence of Elk-1 in axonal projections of largely post-mitotic adult hippocampal sections has been reported. This finding has initially led us to a basic question: how is Elk-1 anchored to neuronal projections? To that(More)
BACKGROUND Evidence synthesis methods enabling direct and indirect comparisons over the entire set of relevant clinical data produce quantitative point estimates for the treatments contrasts between competing interventions, and provide a hierarchical rank ordering between them. We aimed to provide evidence-based guidance on the efficacy and all-cause(More)
Randomized placebo-controlled trials (RCTs) are standard for assessing efficacy and safety of treatments. We pursued preliminary indications that some factors are associated differentially with responses to placebo or drugs in RCTs for bipolar mania. We meta-analysed data from RCTs to assess influences of study-site count, subjects' age, sex distribution,(More)
OBJECTIVES There is a relationship between nonresponsiveness to hepatitis B virus (HBV) vaccine and certain human leukocyte antigen (HLA) genotypes. In healthy population, 4-10% vaccine recipients fail to produce protective levels of antibodies to the HBV vaccine after standard immunization depending upon age and the presence of various underlying diseases.(More)
OBJECTIVES To investigate the characteristics of patients with rapid cycling bipolar illness. METHODS The charts of bipolar patients treated at the Massachusetts General Hospital Bipolar Clinic were reviewed for age of the first affective episode, demographics and history of rapid cycling. RESULTS Data from 223 bipolar-I-II patients, of whom 11.7% were(More)
