Pulmonary Impedance and Pulmonary Doppler Trace in the Perioperative Period.
Pulmonary hypertension and associated vascular changes may frequently accompany left-sided heart disease in the adult cardiac surgical population. Perioperative assessment of right ventricular function using echocardiography is well established. In general, understanding the constraints upon which the right ventricle must work is mostly limited to invasive monitoring consisting of pulmonary artery pressures, cardiac output, and pulmonary vascular resistance. ⋯ The measurement of acceleration time, the time from onset to peak flow velocity is an indicator of constraint to ejection; shortened times have been associated with increased pulmonary vascular resistance and pressure. Understanding the changes in the pulmonary arterial system in disease and the physics of the hemodynamic alterations are essential in interpreting pulmonary artery Doppler data. Analyzing pulmonary artery Doppler flow signals may assist in the evaluation of right ventricular function in patients with pulmonary vascular disease.

Randomized Controlled Trial
Home-based constraint-induced movement therapy for patients with upper limb dysfunction after stroke (HOMECIMT): a cluster-randomised, controlled trial.
Constraint-induced movement therapy (CIMT) is recommended for patients with upper limb dysfunction after stroke, yet evidence to support the implementation of CIMT in ambulatory care is insufficient. We assessed the efficacy of home CIMT, a modified form of CIMT that trains arm use in daily activities within the home environment. ⋯ German Federal Ministry of Education and Research.

To compare knee confidence and kinesiophobia (fear of re-injury) in those with and without knee osteoarthritis following anterior cruciate ligament reconstruction, and determine whether poorer knee confidence is associated with greater kinesiophobia, worse knee-related symptoms, and functional impairments in those with knee osteoarthritis. ⋯ Psychological impairments are evident in people with knee osteoarthritis following anterior cruciate ligament reconstruction, compared to those without. Future studies should further investigate the psychological impairments associated with knee osteoarthritis after anterior cruciate ligament reconstruction.

ReviewRegional Anesthesia in Patients With Preexisting Neurologic Disease.
Since publication of initial recommendations in 2008, there is limited new information regarding the performance of regional anesthesia in patients with preexisting neurologic diseases. However, the strength of evidence has increased since 2008 regarding (1) the concern that diabetic nerves are more sensitive to local anesthetics and perhaps more susceptible to injury and (2) the concern that performing neuraxial anesthesia and analgesia in patients with preexisting spinal canal pathology may increase the risk of new or worsening neurologic symptoms. This increased evidence reinforces our initial recommendations. In addition, since the initial recommendations in 2008, the concept of postsurgical inflammatory neuropathy has been described and is potentially a contributor to postoperative neurologic dysfunction.
