In 48 conscious resting subjects we examined the temporal coupling of heart beat timing and the onset of inspiration (cardioventilatory coupling), and the relationship between coupling and spectral indices of autonomic function. Using the proportional Shannon entropy (SH(alpha)) of the RI(-1) interval (interval between inspiration and the preceding ECG R(More)
OBJECTIVE To evaluate the long-term outcome after intramedullary nailing of tibial shaft fracture. DESIGN Retrospective, cross-sectional study. SETTING Level I, Trauma Center. METHODS Retrospective review of 294 patients treated with intramedullary nailing after tibial shaft fracture from 1998 to 2008. The participants completed Knee injury and(More)
OBJECTIVE To determine the incidence of central catheter-related bloodstream infection (CR-BSI) and to compare patient and catheter characteristics of those with and without CR-BSI from a clinically suspected subgroup. Secondly, to assess the efficacy of the acridine orange leucocyte cytospin test (AOLC) as a rapid in situ method of detecting central venous(More)
We studied the effectiveness of two nonanatomical endoscopic dexterity training models: "Choose the Hole" and Dexter. Effectiveness was assessed in terms of time spent training, subjective rating, performance on an anatomical manikin, and clinical performance on fellow participants who acted as awake subjects. Forty-three anesthesia specialists, trainees,(More)
We examined interbreath interval (IBI) time series of 19 term infants during active and quiet sleep for fractal properties using Fano factor analysis. For each time series we calculated the fractal exponent (alpha), comparing alpha for the original time series with two forms of surrogate data, a temporally independent surrogate set and an autoregressive(More)
Although epidemiologic studies of tibial plateau fractures have been conducted, none have included geographically defined populations or a validated fracture classification based on computed tomography (CT). The goals of this study were to provide up-to-date information on the incidence and basic epidemiology of tibial plateau fractures in a large(More)
INTRODUCTION In Denmark, approximately 300,000 patients have a diabetes mellitus diagnosis. Recently published guidelines emphasise that health-care professionals who are in direct contact with citizens should be aware of the importance of prevention and early detection of diabetic foot ulcers. The objective of this study was to evaluate the mortality,(More)
Recent studies have found that poor cardiopulmonary resuscitation (CPR) is commonly performed in resuscitation attempts, both by health professionals and lay people. One of the contributing factors to poor performance of CPR may be poor initial teaching. This study was conducted to investigate the quality of 14 CPR courses complying with New Zealand(More)
OBJECTIVES We assessed the impact of restaurant menu calorie labels on food choices and intake. METHODS Participants in a study dinner (n=303) were randomly assigned to either (1) a menu without calorie labels (no calorie labels), (2) a menu with calorie labels (calorie labels), or (3) a menu with calorie labels and a label stating the recommended daily(More)
The respiratory component of heart rate variability (respiratory sinus arrhythmia, RSA) has been associated with improved pulmonary gas exchange efficiency in humans via the apparent clustering and scattering of heart beats in time with the inspiratory and expiratory phases of alveolar ventilation, respectively. However, since human RSA causes only marginal(More)
