Realtime physical simulator for virtual reality sailing by patients with spinal cord injury: an innovative voyage.

Background: The aim of this study was to explore whether sail training using a VSail® simulator would allow people with spinal cord injuries (SCI) to learn to sail in a safe controlled environment and then sail competently on the water in wind of moderate strength (12 knots). A battery of physical tests and questionnaires was used to evaluate possible improvements in health and well-being as a consequence of participation in the trial.

Methods: Twenty participants were recruited with the assistance of their physicians from The International Center for Spinal Cord Injury, Kennedy Krieger Institute.

Hospital policy of tranexamic acid to reduce transfusion in major non-cardiac surgery (TRACTION): protocol for a phase IV randomised controlled trial.

Introduction: Tranexamic acid (TXA) is an inexpensive and widely available medication that reduces blood loss and red blood cell (RBC) transfusion in cardiac and orthopaedic surgeries. While the use of TXA in these surgeries is routine, its efficacy and safety in other surgeries, including oncologic surgeries, with comparable rates of transfusion are uncertain. Our primary objective is to evaluate whether a hospital-level policy implementation of routine TXA use in patients undergoing major non-cardiac surgery reduces RBC transfusion without increasing thrombotic risk.

Granuloprival cerebellar cortical degeneration in a Yorkshire Terrier and Lagotto Romagnolo dog.

Granuloprival degeneration is an uncommon form of cerebellar cortical degeneration (CCD). A 3-month-old Yorkshire Terrier and a 7-month-old Lagotto Romagnolo dog were presented with a history of progressive cerebellar dysfunction including wide-based stance, cerebellar ataxia, intention tremors, and loss of menace response despite normal vision. Magnetic resonance imaging of the brain identified marked diffuse decrease of the cerebellum size.

The Repeatability and Agreement of Ocular Parameters Measured with the MYAH and Myopia Master Devices between Expert and Non-Expert Practitioners.

In myopia control, it is essential to measure the axial length (AL) and corneal parameters, and to monitor whether changes in these parameters have occurred over time. The aim of this study was to analyse the repeatability and agreement between expert and non-expert practitioners in ocular parameters measured by the MYAH and Myopia Master. Three repeated measurements ( = 42) were recorded with the MYAH and Myopia Master by two (an expert and a non-expert) observers in a randomized order.
