In this article, we review findings on the role of negative cognitive styles and information processing biases as cognitive vulnerabilities to unipolar and bipolar mood disorders. We first briefly describe the cognitive theories of unipolar depression and the logic of their extension to bipolar disorders, as well as methodological issues involved in conducting vulnerability research, particular...

Modern unipolar hip hemiarthroplasty, commonly used for displaced femoral neck fracture, is now modular, with both a variable length cobalt-chromium adapter-sleeve and large femoral head. Patients with these modular components may develop symptomatic trunnion corrosion, with elevated serum metal levels. We report the case of an 82-year-old woman, 5.5 years after a modular unipolar hip hemiarthr...

We undertook a cemental unipolar proximal femoral endoprosthetic replacement in 131 patients with a mean age of 50 years (2 to 84). Primary malignant tumours were present in 54 patients and 67 had metastatic disease. In addition, eight patients had either lymphoma or myeloma and two had non-oncological disorders. The mean follow-up was 27 months (0 to 180). An acetabular revision was required l...

Recent advances in wireless communication systems have increased the throughout over wireless channels. Unipolar communications systems can transmit information using only real and positive signals. We consider two unipolar OFDM techniques such as FLIP-OFDM and ACO-OFDM. This includes a variety of physical channels ranging from optical, to RF wireless using amplitude modulation with non-coheren...

Psychological disorders, particularly mood disorders, such as unipolar depression, are often accompanied by comorbid sleep disturbances, such as insomnia, restless sleep, and restricted sleep duration. The nature of the relationship between unipolar depression and these sleep disturbances remains unclear, as sleep disturbance may be a risk factor for development, an initial manifestation of the...

Consistent with the "scar hypothesis", according to which mood depression might impact personality, we examined the effect of unipolar and hypomanic mood disturbances on cluster B (i.e., narcissistic, histrionic, and borderline) personality disorder features. Data from 113 suicidal young adults were utilized, and cross-lagged associations between unipolar and hypomanic mood disturbances and clu...

BACKGROUND Coping with Depression Course (CWD) has shown to be effective in the treatment of depression. However, there are very few randomized controlled trials on unipolar depression in adults. AIMS To test the effect of a modified CWD on unipolar depression in a randomized controlled trial design in adults. METHODS Participants were recruited through mass media, tested by BDI and clinica...
