Health-related quality of life in stroke patients questionnaire, short version (HRQOLISP-40): validation for its use in Colombia.

Background: The health-related quality of life in stroke patients (HRQOLISP-40, short version) survey was developed in Nigeria and constitutes a 40-item, multidimensional, self-administrated questionnaire. We assessed the validity and reliability of the HRQOLISP-40 Spanish version for stroke patients in Colombia.

Methods: The analysis included factor analysis, confirmatory factor analysis, Rasch analysis, convergent validity, internal consistency (261 stroke patients), test-retest reliability (73 patients assessed at two different times) and sensitivity to change (46 patients assessed before and after a rehabilitation intervention).

Factors associated to institutionalization and mortality over three years, in elderly people with a hip fracture-An observational study.

Objective: To identify the factors associated to institutionalization and mortality in elderly patients with hip fractures (HF).

Design: Thirty-six months observational study.

Setting: A post-acute rehabilitation ward.

An automatic tool to facilitate the statistical group analysis of DTI.

Background: Users may have difficulty calculating DTI group statistics since they need to master several complex tools that require high user intervention. A tool called DTIStatistics for the automatic and easy calculation of DTI group statistics was developed to reduce analysis times and possible errors.

Methods: The proposed software was designed by using a user-centred methodology in which we performed an iterative usability evaluation with an expert committee.

Fast-food and commercial baked goods consumption and the risk of depression.

Objective: Whereas the relationship between some components of diet, such as n-3 fatty acids and B-vitamins, and depression risk has been extensively studied, the role of fast-food or processed pastries consumption has received little attention.

Design: Consumption of fast food (hamburgers, sausages, pizza) and processed pastries (muffins, doughnuts, croissants) was assessed at baseline through a validated semi-quantitative FFQ. Participants were classified as incident cases of depression if they reported a physician diagnosis of depression or the use of antidepressant medication in at least one of the follow-up questionnaires.

[Study of the evolution of some monocytic parameters and neuroendocrine function tests in depressed patients].

Background: The development, evaluation and use of biological markers is extremely important in Psychiatry. However, with certain exceptions, truly sensitive and specific markers have not still emerged. Several studies have reported immune cellular and humoral dysfunction during depression.
