OBJECTIVE To compare sensory processing, coping strategies, and quality of life (QoL) in unipolar and bipolar patients; to examine correlations between sensory processing and QoL; and to investigate the relative contribution of sociodemographic characteristics, sensory processing, and coping strategies to the prediction of QoL. METHODS Two hundred sixty-seven participants, aged 16-85 years (5...

BACKGROUND Transvenous implantable cardioverter-defibrillators provide significant advantages in the treatment of patients with life-threatening ventricular arrhythmias. However, present technology requires considerable electrophysiology expertise, multiple incisions, and long operative times for successful implementation. METHODS AND RESULTS In this study, we present a prototype of a new, ea...

Diffusion tensor imaging (DTI) of moving organs is gaining increasing attention but robust performance requires sequence modifications and dedicated correction methods to account for system imperfections. In this study, eddy currents in the "unipolar" Stejskal-Tanner and the velocity-compensated "bipolar" spin-echo diffusion sequences were investigated and corrected for using a magnetic field m...

The present study compared electroporation efficiency of bipolar and unipolar nanosecond electric field oscillations (NEFO). Bipolar NEFO was a damped sine wave with 140 ns first phase duration at 50% height; the peak amplitude of phases 2-4 decreased to 35%, 12%, and 7% of the first phase. This waveform was rectified to produce unipolar NEFO by cutting off phases 2 and 4. Membrane permeabiliza...

Only ash remains after fire is gone. Metaphorically mania is the fire and depression its ash (Koukopoulos & Ghaemi 2009). What is the reason, when there is just fire without ash? Unipolar mania has been described in the literature. Different terms have been used like recurrent mania, chronic mania and persistent mania. But these are scarce diagnoses in psychiatric routine. This topic has got li...

BACKGROUND Amotivation, or decisional anhedonia, is a prominent and disabling feature of depression. However, this aspect of depression remains understudied, and no prior work has applied objective laboratory tests of motivation in both unipolar and bipolar depression. METHODS We assessed motivation deficits using a Progressive Ratio Task (PRT) that indexes willingness to exert effort for mon...

AIM The purpose of the research was to analyse the structure of social networks as well as types and sources of support received by patients with unipolar and bipolar disease. METHOD Assessment was made according to Bizoń's method and Cohen's ISEL. RESULTS It has been shown that the functioning of social networks of patients diagnosed as having unipolar affective disorders differs from the ...

We compared two methods of delivering single damped sine-wave defibrillator pulses to the coronary sinus orifice in 20 dogs. Ten dogs had "unipolar" (coronary sinus to precordial disc) and 10 had "bipolar" (coronary sinus proximal to coronary sinus distal electrode) discharges. Delivered voltage, current, and energy were recorded during each pulse. Electrophysiologic testing was done before and...

Single-lead DDD pacing using unipolar or bipolar stimulation has been limited by high atrial thresholds. Overlapping biphasic (OLBI) waveform stimulation via atrial floating ring electrodes may preferentially enhance atrial stimulation and avoid diaphragmatic pacing. Single-lead DDD pacing using the OLBI pacing configuration was studied in 12 patienta (6 male, 6 female, mean age 74±7 years) wit...

Concerns have recently been raised about a possible link between suicidal ideation and the use of SSRIs in teenagers diagnosed with unipolar depression, such that the USA FDA and UK CSM have issued warnings regarding the use of SSRIs in adolescents with depression. We investigated this phenomenon first by recognizing that the initial presentation of unipolar and bipolar depression may only diff...
