A tendency toward abstract and overgeneral processing is a cognitive bias hypothesized to causally contribute to symptoms of depression. This hypothesis predicts that training dysphoric individuals to become more concrete and specific in their thinking would reduce depressive symptoms. To test this prediction, 60 participants with dysphoria were randomly allocated either to (a) concreteness tra...

This paper analyzes the optimal assignment of objects which arrive sequentially to agents organized in a waiting list. Applications include the assignment of social housing and organs for transplants. We analyze the optimal design of probabilistic queuing disciplines, punishment schemes, the optimal timing of applications and information releases. We consider three efficiency criteria: the vect...

Portal vein thrombosis (PVT) complicates the liver transplant operation and potentially affects waiting list survival. The implications on calculations of survival benefit, which balance both waiting list and posttransplant survival effects of PVT, have not been determined. The objective of this study is to describe the effect of PVT on the survival benefit of liver transplantation. Using Scien...

The demand for orthodontic treatment is increasing greatly in the present days. In a country like India which has a humongous population of 1210 million the management strategies need to be formulated so as to give justice to the deprived. The prioritization should be based on the extent to which the malocclusion handicaps the patient and his motivation to commence the treatment. Eishenhower bo...

DESIGN A descriptive survey of patients' views conducted immediately after angiography and treatment counselling. SUBJECTS 136 patients who were awaiting coronary angioplasty in either of the two regional cardiology centres in Northern Ireland. RESULTS Abo...

BACKGROUND Hepatopulmonary syndrome is formed by a triad of liver disease, intrapulmonary vascular dilatation and changes in blood gases. This condition is present in 4-32% of patients with cirrhosis. AIM To analyze the blood gas changes data of patients in liver-transplant waiting list. METHOD Clinical data of 279 patients in liver transplantation waiting list in May 2013 were studied. Ove...
