The haemodynamic response to myocardial ischaemia in patients with variant angina during ambulatory activity is unknown. Ambulatory pulmonary artery pressure monitoring with a transducer tipped catheter and simultaneous frequency modulated electrocardiograms was used to assess changes in left ventricular function in five male patients (mean age 51.8 years) during variant angina; four patients h...

UNLABELLED ST segment depression (STDE) has been found to be associated with cardiovascular disease in the elderly. Studies of the relation of ambulatory STDE to cognitive function in elderly persons aged 80 years or above is lacking. OBJECTIVE To study the association between STDE and cognition. DESIGN AND PARTICIPANTS A cross-sectional cohort study of 88 81-year-old men from the populatio...

The prognostic value of central systolic blood pressure has been established recently. At present, its noninvasive assessment is limited by the need of dedicated equipment and trained operators. Moreover, ambulatory and home blood pressure monitoring of central pressures are not feasible. An algorithm enabling conventional automated oscillometric blood pressure monitors to assess central systol...

BACKGROUND An increasing number of centers are using active rehabilitation and ambulation for critically ill patients on extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation. This investigation assessed the economic impact at a single center of ambulatory versus non-ambulatory ECMO strategies as a bridge to lung transplantation. METHODS We conducted a single-center r...

OBJECTIVE To compare the performance of third-year medical students who completed the ambulatory component of their pediatric rotation in a community setting with the performance of third-year medical students who had their ambulatory experience on campus. METHODS As part of a pilot project to implement a third-year Multidisciplinary Ambulatory Clerkship, 61 third-year medical students spent ...

This article explores whether Medicare pays more for the same outpatient services provided in an acute specialty hospital than in an ambulatory surgery center (ASC). How financially dependent a specialty hospital is on ASC-eligible services is also investigated. Medicare outpatient claims in 43 orthopedic and 12 surgical specialty hospitals in 2004 were repriced using ASC pricing software. Paym...

PURPOSE OF REVIEW The purpose of this article is to discuss the anesthetic considerations of obstructive sleep apnea (OSA) patients undergoing ambulatory surgery and the current recommendations based on recent evidence. RECENT FINDINGS It is documented that 75% of patients with high propensity for OSA were not diagnosed prior to ambulatory surgery. An OSA screening questionnaire, the STOP-Ban...

To the Editor: It was demonstrated that a higher peritoneal membrane solute transport rate is associated with a higher mortality risk and a trend to higher technique failure. It has been suggested that the bioincompatible nature of conventional peritoneal dialysis (PD) solutions contributes to the structural peritoneal membrane changes that lead to deterioration in solute transport characterist...

Background: Patients undergoing hemodialysis (HD) have difficulty performing activities of daily living (ADL) compared to healthy people. ADL difficulty is an early predictor of loss of independence and mortality in older community-living people. However, determinants of ADL difficulty in HD patients have not been clarified. This study aimed to identify factors associated with ADL difficulty in...

OBJECTIVE To conduct a randomized trial to test the primary hypothesis that once-daily tadalafil, administered orally for 48 weeks, lessens the decline in ambulatory ability in boys with Duchenne muscular dystrophy (DMD). METHODS Three hundred thirty-one participants with DMD 7 to 14 years of age taking glucocorticoids were randomized to tadalafil 0.3 mg·kg-1·d-1, tadalafil 0.6 mg·kg-1·d-1, o...
