BACKGROUND: Handheld ECG event recorders are useful for rhythm monitoring but only record a single lead, which may limit interpretation. We sought to investigate if a multi-lead ECG may be reconstituted using this device, and aimed to evaluate diagnostic accuracy. METHODS: A commercially-available handheld bipolar ECG event recorder was used to reconstruct a 9-lead ECG (leads I, II and III, V1-6). Tracings were analyzed independently by a cardiologist and a fellow...

Prominent cognitive deficits have been documented in bipolar disorder, and multiple studies suggest that these deficits can be observed among non-affected first-degree relatives of those with bipolar disorder. Although there is variability in the degree of cognitive deficits, these deficits are robustly relevant for functional outcomes. A separate literature documents clear difficulties in emotionality, emotion regulation, and emotion-relevant impulsivity within bipolar disorder, and demonstrates that these emotion-relevant variables are also central to outcome...

Depressive episodes are a major cause of morbidity and dysfunction in individuals suffering from bipolar disorder. Currently available treatments for this condition have limited efficacy and new therapeutic options are needed. Extensive research in the pathophysiology of bipolar disorder points to the existence of mitochondrial and bioenergetic dysfunction. We hypothesized that creatine monohydrate, a nutraceutical that works as a mitochondrial modulator, would be effective as an adjunctive therapy for bipolar depression...

Importance: Bipolar disorder (BD) overlaps schizophrenia in its clinical presentation and genetic liability. Alternative approaches to patient stratification beyond current diagnostic categories are needed to understand the underlying disease processes and mechanisms. Objective: To investigate the association between common-variant liability for schizophrenia, indexed by polygenic risk scores (PRSs), and psychotic presentations of BD. Design, Setting, and Participants: This case-control study in the United Kingdom used multinomial logistic regression to estimate differential PRS associations across categories of cases and controls...

Epigenetic effects of medications are an evolving field of medicine, and can change the landscape of drug development. The aim of this paper is to systematically review the literature of the relationship between common medications used for treatment of bipolar disorders and epigenetic modifications. MedLine/PubMed searches were performed based on pre-specified inclusion criteria from inception to November 2017. Six animal and human studies met the inclusion criteria. These studies examined the epigenetic changes in the main classes of medications that are used in bipolar disorders, namely mood stabilizers and antipsychotics...

Bipolar disorder types I (BD I) and II (BD II) might present different cortico-brainstem circuit dysfunctions under external emotions, which might be reflected by the blink reflex. We therefore invited 32 BD I and 23 BD II patients, and 46 healthy volunteers to answer the Mood Disorder Questionnaire, the Hypomania Checklist-32, and the Plutchik - van Praag Depression inventory, and to undergo the blink reflex test under external emotions (emotional pictures plus sounds) of Disgust, Erotica, Fear, Happiness, and Sadness...

Proper muscle activity quantification is highly relevant to monitor and treat spastic cocontraction. As activity may distribute unevenly within muscle volumes, particularly for pennate calf muscles, surface electromyograms (EMGs) detected by traditional bipolar montage may provide biased estimations of muscle activity. We compared cocontraction estimates obtained using bipolar vs grids of electrodes (high-density EMG, HD-EMG). EMGs were collected from medial gastrocnemius, soleus and tibialis anterior during isometric plantar and dorsi-flexion efforts at three levels (30%, 70% and 100% MVC), knee flexed and extended...

BACKGROUND: To date, shortened versions of the Hypomania Checklist-32 (HCL-32) were proposed to overcome the limitation of a lengthy format; however, a cross-validation study is currently needed to identify which shorter version may function optimally in a clinical sample. METHODS: In a Korean patient sample with bipolar disorder (BD) and major depressive disorder (MDD) (BD-I n = 84, BD = II n = 145, MDD n = 285), we examined the reliability and screening property of three shorter versions of the HCL (HCL-20, -16, -8) in comparison with the full HCL-32...

BACKGROUND: Anxiety symptoms are common in bipolar disorder. We explored the effect of anxiety on the outcome of acute and continuation pharmacotherapy of bipolar II depression. METHODS: Data were derived from a randomized double-blind 12-week acute (N = 129) and 6-month continuation (N = 55) comparison of venlafaxine versus lithium monotherapy in bipolar II depression in adults. We distinguished between the items of the Hamilton Rating Scale for Depression (HRSD) that capture depression vs...

Ganglion cells (GCs) are fundamental to retinal neural circuitry, processing photoreceptor signals for transmission to the brain via their axons. However, much remains unknown about their role in vision and their vulnerability to disease leading to blindness. A major bottleneck has been our inability to observe GCs and their degeneration in the living human eye. Despite two decades of development of optical technologies to image cells in the living human retina, GCs remain elusive due to their high optical translucency...

Bipolar disorder is associated with decreased quality of life, especially during depressive episodes. There are few studies that have examined whether quality of life improves following pharmacological treatments of bipolar depression. In this exploratory study, we examined the effects of antidepressant versus mood stabilizer monotherapy on quality of life ratings in bipolar II subjects during acute (12 week) treatment. Data were derived from a randomized double-blind comparison of venlafaxine (n = 65) versus lithium (n = 64) monotherapy...

Latinos with bipolar disorder (BD) have a high rate of nonadherence to psychiatric medication and treatment for other medical conditions such as cardiovascular disease (CVD) risk factors than non-Latinos with BD. The aim of this study is to identify patients' perspectives on the reasons for nonadherence to psychiatric medication and for CVD risk factors conditions in outpatients with BD. Three focus group sessions were held for a total of 22 adults ranging from 23 to 60 years old. Participants had BD, Type I/II and CVD risk factors...

BACKGROUND: Highly hypnotizable individuals have impaired executive function, elevated motor impulsivity and increased emotional sensitivity, which are sometimes found in bipolar disorder patients. It is then reasonable to assume that certain aspects of hypnotic susceptibility differ with the types of bipolar disorder. METHODS: The Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C) test, the Mood Disorder Questionnaire (MDQ), the Hypomanic Checklist-32 (HCL-32) and the Plutchick-van Praag Depression Inventory (PVP) were applied to 62 patients with bipolar I disorder, 33 bipolar II disorder, and 120 healthy volunteers...

In their late (3(th) and 4th) larval stages, caterpillars of the myrmecophilous lycaenid (Lepidoptera) species Polyommatus coridon and P.icarus respectively, possess on their 8th abdominal segment two eversible so called tentacle organs (TOs). Previous histological and behavioural results have proposed that the TOs may release a volatile substance that elicits "excited runs" in attendant ants. In our study we investigated for the first time the temporal in- and eversion pattern of TOs. Using nerve tracing, Micro-CT, light- and electron microscopy techniques we studied (i) the histology of the 8th abdominal segment, (ii) the fine structure of the cuticular and cellular apparatus of the TOs, (iii) the attachment sites of the retractor muscle of each TO and (iv) the fine structure of the long slender tentacle hairs which are exposed to the outside, when the TOs are everted and fold back into the TO-sac during inversion...
