Cortical and subcortical functional connectivity and cognitive impairment in Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disease with cognitive as well as motor impairments. While much is known about the brain networks leading to motor impairments in PD, less is known about the brain networks contributing to cognitive impairments. Here, we leveraged resting-state functional magnetic resonance imaging (rs-fMRI) data from the Parkinson's Progression Marker Initiative (PPMI) to examine network dysfunction in PD patients with cognitive impairment.

Central precuneus lesions are associated with impaired executive function.

The functional roles of the precuneus are unclear. Focal precuneus lesions are rare, making it difficult to identify robust brain-behavior relationships. Distinct functional subdivisions of the precuneus have been proposed based on unique connectivity profiles.

Neuromodulation of cognition in Parkinson's disease.

Neuromodulation is a widely used treatment for motor symptoms of Parkinson's disease (PD). It can be a highly effective treatment as a result of knowledge of circuit dysfunction associated with motor symptoms in PD. However, the mechanisms underlying cognitive symptoms of PD are less well-known, and the effects of neuromodulation on these symptoms are less consistent.

The Impact of Telemedicine on Pediatric Critical Care Triage.

Objective: To examine the relationship between pediatric critical care telemedicine consultation to rural emergency departments and triage decisions. We compare the triage location and provider rating of the accuracy of remote assessment for a cohort of patients who receive critical care telemedicine consultations and a similar group of patients receiving telephone consultations.

Design: Retrospective evaluation of consultations occurring between April 2012 and March 2016.

Prevalence of Chest Pain, Depression, Somatization, Anxiety, Global Distress, and Substance Use among Cardiac and Pulmonary Rehabilitation Patients.

Psychosocial factors of cardiovascular disease receive a preponderance of attention. Little attention is paid to psychosocial factors of pulmonary disease. This paper sought to describe psychosocial characteristics and to identify differences between cardiac and pulmonary patients entering a phase II rehabilitation program.
