The intention to exercise and the execution of exercise among persons with multiple sclerosis--a qualitative metasynthesis.

Purpose: This review was designed as a qualitative metasynthesis aiming to identify factors influencing the intention to exercise and the execution of exercise among persons with multiple sclerosis (PwMS).

Method: Based on principles laid out by Sandelowski and Barroso, this qualitative metasynthesis started with a systematic literature search for studies of PwMS's experiences relating to exercise in the following databases: CINAHL, Rehabilitation and Sports Medicine Source, PubMed, Web of Science and Psychology & Behavioral Science. The metasynthesis procedure also included critical appraisal using the Consolidated Criteria for Reporting Qualitative Research checklist, and integrating synthesis of the articles' findings.

Infrared skin temperature measurements for monitoring health in pigs: a review.

Infrared temperature measurement equipment (IRTME) is gaining popularity as a diagnostic tool for evaluating human and animal health. It has the prospect of reducing subject stress and disease spread by being implemented as an automatic surveillance system and by a quick assessment of skin temperatures without need for restraint or contact. This review evaluates studies and applications where IRTME has been used on pigs.

The use of sequential organ failure assessment parameters in an awake porcine model of severe Staphylococcus aureus sepsis.

The human sequential organ failure assessment (SOFA) scoring system is used worldwide in intensive care units for assessing the extent of organ dysfunction/failure in patients with severe sepsis. An increasing number of septic cases are caused by Gram-positive bacteria as Staphylococcus aureus. The aim of the current study was to apply the human SOFA parameters in an awake, porcine model of severe S.

Optimum fuzzy filters for phase-contrast magnetic resonance imaging segmentation.

Purpose: To develop and validate a multidimensional segmentation and filtering methodology for accurate blood flow velocity field reconstruction from phase-contrast magnetic resonance imaging (PC MRI).

Materials And Methods: The proposed technique consists of two steps: (1) the boundary of the vessel is automatically segmented using the active contour approach; and (2) the noise embedded within the segmented vector field is selectively removed using a novel fuzzy adaptive vector median filtering (FAVMF) technique. This two-step segmentation process was tested and validated on 111 synthetically generated PC MRI slices and on 10 patients with congenital heart disease.

Introduction of a new optimized total cavopulmonary connection.

Background: Several variations of the total cavopulmonary connection (TCPC) have been investigated for favorable fluid mechanics and flow distribution. This study presents a hemodynamically optimized TCPC configuration code-named "OptiFlo." Featuring bifurcated vena cava (superior venacava to inferior vena cava SVC/IVC), it was designed to lower the fluid mechanical power losses in the connection and to ensure proper hepatic blood perfusion to both lungs.
