Support for using a three-dimensional anatomy application over anatomical atlases in a randomized comparison.

To investigate to what extent the use of a three-dimensional (3D) anatomy computer application can improve the acquisition of anatomical knowledge compared with anatomical atlases, junior and advanced medical students participated in an experiment. Participants were asked to answer anatomical questions with the use of a 3D anatomy application (developed at the University Medical Center in Utrecht, the Netherlands) or anatomy atlases. Every student had to complete two assignments, either with an atlas or with the 3D anatomy application.

The effect of visual feedback and training in auditory-perceptual judgment of voice quality.

The aim of the present investigation was to evaluate the effect of visual feedback on rating voice quality severity level and the reliability of voice quality judgment by inexperienced listeners. For this purpose two training programs were created, each lasting 2 hours. In total 37 undergraduate speech-language therapy students participated in the study and were divided into a visual plus auditory-perceptual feedback group (V + AF), an auditory-perceptual feedback group (AF), and a control group with no feedback (NF).

Arterial pressure waveform analysis versus thermodilution cardiac output measurement during open abdominal aortic aneurysm repair: a prospective observational study.

Background: Arterial pressure waveform analysis enables continuous, minimally invasive measurement of cardiac output. Haemodynamic instability compromises the reliability of the technique and a means of maintaining accurate measurement in this circumstance would be useful.

Objectives: To investigate the accuracy, precision and trending ability of arterial pressure waveform cardiac output obtained with FloTrac/Vigileo, versus pulmonary artery thermodilution in patients undergoing elective open abdominal aortic aneurysm repair.

Influence of early goal-directed therapy using arterial waveform analysis on major complications after high-risk abdominal surgery: study protocol for a multicenter randomized controlled superiority trial.

Background: Early goal-directed therapy refers to the use of predefined hemodynamic goals to optimize tissue oxygen delivery in critically ill patients. Its application in high-risk abdominal surgery is, however, hindered by safety concerns and practical limitations of perioperative hemodynamic monitoring. Arterial waveform analysis provides an easy, minimally invasive alternative to conventional monitoring techniques, and could be valuable in early goal-directed strategies.

Anaerobic performance in children with cerebral palsy compared to children with typical development.

Purpose: Using a locomotor-based field test of anaerobic performance, this study compared the anaerobic performance of children with spastic cerebral palsy (CP) who walk without support with that of peers who are typically developing.

Malnutrition and risk of malnutrition in patients with stroke: prevalence during hospital stay.

Background: Although various studies have shown high prevalence of malnutrition in hospitalized patients with stroke, recent studies on how the nutritional status of patients with acute stroke develops during the first weeks of hospital stay are scarce. Information is lacking concerning the identification of patients with stroke who are at risk of malnutrition during an acute hospital stay, because these patients may have a significant chance to improve their nutritional status.

Purpose: This study aimed to investigate the prevalence of malnutrition and risk of malnutrition of patients with acute stroke during the first 10 days of hospitalization.

CT air trapping is independently associated with lung function reduction over time.

Purpose: We aimed to study the association between lung function decline and quantitative computed tomography (CT) air trapping.

Materials And Methods: Current and former heavy smokers in a lung cancer screening trial underwent volumetric low-dose CT in inspiration and expiration. Spirometry was obtained at baseline and after 3 years.

Cannabinoid receptor-2 immunoreactivity is associated with survival in squamous cell carcinoma of the head and neck.

The prediction of progression of individual tumours, prognosis, and survival in squamous cell carcinoma (SCC) of the head and neck is difficult. Cannabinoid-1 (CB1) and cannabinoid-2 (CB2) receptor expression is related to survival in several types of cancer, and the aim of this study was to find out whether the expression of CB1 and CB2 receptors is associated with survival in primary SCC of the head and neck. We made immunohistochemical analyses of the cannabinoid receptors on tissue arrays from 240 patients with the disease.
