Physiological measures and anatomical correlates of subthalamic deep brain stimulation effect on gait in Parkinson's disease.

We examined whether conflicting visual and non-visual information leads to gait abnormalities and how the subthalamic deep brain stimulation (STN DBS) influences gait dysfunction in Parkinson's disease (PD). We used a motion capture system to measure the kinematics of the lower limbs during treadmill walking in immersive virtual reality. The visual information provided in the virtual reality paradigm was modulated to create a mismatch between the optic-flow velocity of the visual scene and the walking speed on the treadmill.

Henry Ford HEART Score Randomized Trial: Rapid Discharge of Patients Evaluated for Possible Myocardial Infarction.

Background: Hospital evaluation of patients with chest pain is common and costly. The HEART score risk stratification tool that merges troponin testing into a clinical risk model for evaluation emergency department patients with possible acute myocardial infarction (AMI) has been shown to effectively identify a substantial low-risk subset of patients possibly safe for early discharge without stress testing, a strategy that could have tremendous healthcare savings implications.

Method And Results: A total of 105 patients evaluated for AMI in the emergency departments of 2 teaching hospitals in the Henry Ford Health System (Detroit and West Bloomfield, MI), between February 2014 and May 2015, with a modified HEART score ≤3 (which includes cardiac troponin I <0.

Ventricular tachycardia cardiac arrest during central line placement.

Central venous catheterization is often necessary for the safe administration of medications that are caustic to peripheral veins, to place temporary transvenous pacemakers and to provide invasive hemodynamic monitoring in the critically ill. While a wide range of complications are known to occur with insertion of these catheters, there is a paucity of cases associated with cardiac arrest during the catheters placement. We describe an unusual case of sustained ventricular tachycardia and subsequent cardiac arrest that occurred during an ultrasound guided central venous catheter placement for a patient in septic shock.

An international effort towards developing standards for best practices in analysis, interpretation and reporting of clinical genome sequencing results in the CLARITY Challenge.

Background: There is tremendous potential for genome sequencing to improve clinical diagnosis and care once it becomes routinely accessible, but this will require formalizing research methods into clinical best practices in the areas of sequence data generation, analysis, interpretation and reporting. The CLARITY Challenge was designed to spur convergence in methods for diagnosing genetic disease starting from clinical case history and genome sequencing data. DNA samples were obtained from three families with heritable genetic disorders and genomic sequence data were donated by sequencing platform vendors.
