The road to gold: Training and peaking characteristics in the year prior to a gold medal endurance performance
2014
Published version of an article in the journal PLoS ONE. Also available from the publisher at: http://dx.doi.org/10.1371/journal.pone.0101796 Open Access Purpose: To describe training variations across the annual cycle in Olympic and World Champion endurance athletes, and determine whether these athletes used tapering strategies in line with recommendations in the literature. Methods: Eleven elite XC skiers and biathletes (4 male; 28±1 yr, 85±5 mL. min-1. kg-1 V̇O2max, 7 female, 25±4 yr, 73±3 mL. min-1. kg-1 V̇O2max) reported one year of day-to-day training leading up to the most successful competition of their career. Training data were divided into periodization and peaking phases and dis…
B‐Mode ultrasonography of the paranasal sinuses compared with CT findings
1992
Ultrasound as a diagnostic aid in the evaluation of the sinuses has been a controversial issue. Sensitivities have been reported from 29% to 100% and specificities from 55% to 99%. These wide variations in results from previous studies may have resulted from technical differences. However, the "gold standard" most often used for comparison has been a Water's view radiograph, which has been shown to correlate poorly with intraoperative and CT scan findings. To our knowledge, no one in the English language literature has evaluated sonography of the sinuses with computed tomography as the gold standard. In addition, evaluation of the ethmoid sinus has been neglected by previous studies that ha…
URINARY DIVERSION AND ORTHOTOPIC BLADDER SUBSTITUTION IN CHILDREN AND YOUNG ADULTS WITH NEUROGENIC BLADDER: A SAFE OPTION FOR TREATMENT?
2000
Combined pharmacotherapy, clean intermittent catheterization and infection prophylaxis is currently the gold standard of treatment for neurogenic bladder. However, as the adolescent gains independence from parental supervision, the intervals of clean intermittent catheterization compliance with medical treatment and regularity of followup examinations may decrease, and neurological and/or orthopedic status may change. This situation sometimes leads to failure of conservative treatment, resulting in incontinence and/or deterioration of the upper urinary tract. A multidisciplinary team was established at our institution 30 years ago to assess all aspects of care for patients with neurogenic b…
Relationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.
2016
Abstract Introduction and objectives The caloric test is the gold standard for the loss of vestibular function diagnosis. The video head impulse test (vHIT) assesses the same reflex by using a video-assisted examination of the impulsive manoeuvre. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at two different moments of their evolution and to check the level of correlation between them and with that of the DHI test. Methods We explored 20 patients with neuritis by using both vHIT and the caloric test on the same day. We assessed the correlation between these two tests and with the D…
Acute appendicitis: should the laparoscopic approach be proposed as the gold standard? Six-year experience in an Emergency Surgery Unit
2016
Acute appendicitis is common in an Emergency Surgery Unit. Although the laparoscopic approach is a method accepted for its treatment, no strong data are available for determining how many procedures must an experienced surgeon carry out for obtaining all the advantages of this technique and if this approach can become the gold standard in the activity of a general emergency unit with senior surgeons variously skilled on the basic laparoscopy. 142 patients that underwent appendectomy (90 laparoscopic, 52 conventional) for acute appendicitis were enrolled in this institutional retrospective cohort study. The surgeons were classified with a descriptor-based grading and divided in two groups re…
Assessment of the relationship between lung parenchymal destruction and impaired pulmonary perfusion on a lobar level in patients with emphysema.
2006
Abstract Purpose To assess the relationship between lung parenchymal destruction and impaired pulmonary perfusion on a lobar level using CT and MRI in patients with emphysema. Material and methods Forty-five patients with severe emphysema (GOLD III and IV) underwent inspiratory 3D-HRCT and contrast-enhanced MR-perfusion (1.5T; 3.5 mm × 1.9 mm × 4 mm). 3D-HRCT data was analyzed using a software for detection and visualization of emphysema. Emphysema was categorized in four clusters with different volumes and presented as overlay on the CT. CT and lung perfusion were visually analyzed for three lobes on each side using a four-point-score to grade the abnormalities on CT (1: predominantly smal…
Comparison of cyclodeviation and duction measurement in Graves' orbitopathy patients using different devices
2011
To compare measurement outcomes of different devices measuring cyclodeviation and ductions in Graves' orbitopathy (GO) patients. Cyclodeviation in GO patients was measured using the Harms tangent screen (HTS), the cycloforometer of Franceschetti, and the synoptometer. Ductions were measured using the modified perimeter, the Goldmann perimeter and the Maddox tangent scale (MTS). In 13 patients, cyclodeviation in primary position, up-, and downgaze was measured with the above-mentioned devices. The mean differences ranged from 0.3º to 3.1º and were smallest between the HTS and the cycloforometer (89% of all measurements within 2º difference). Measurement of abduction, adduction, elevation, an…
Effect of Kernels Used for the Reconstruction of MDCT Datasets on the Semi-Automated Segmentation and Volumetry of Liver Lesions
2014
Purpose: To evaluate the effect of different reconstruction kernels on the semi-automated segmentation of liver lesions in MDCT. Materials and Methods: A total 62 liver lesions were measured by three independent radiologists with the semi-automated segmentation software Oncology-Prototype (Fraunhofer MEVIS, Siemens Healthcare, Germany) using MDCT datasets (3-mm slice thickness, 2-mm increment) reconstructed with standard, soft and detailed kernels (Philips B, A and D). To ensure objective measurements, only lesions with satisfactory initial segmentation were included, and manual correction was not used. The effective diameter and volume were recorded for each lesion. Segmentation in the sof…
Blurring the boundaries between frame-based and frameless stereotaxy: feasibility study for brain biopsies performed with the use of a head-mounted r…
2015
OBJECT Frame-based stereotactic interventions are considered the gold standard for brain biopsies, but they have limitations with regard to flexibility and patient comfort because of the bulky head ring attached to the patient. Frameless image guidance systems that use scalp fiducial markers offer more flexibility and patient comfort but provide less stability and accuracy during drilling and biopsy needle positioning. Head-mounted robot-guided biopsies could provide the advantages of these 2 techniques without the downsides. The goal of this study was to evaluate the feasibility and safety of a robotic guidance device, affixed to the patient’s skull through a small mounting platform, for …
Palliative Care Patients’ Quality of Dying and Circumstances of Death—Comparison of Informal Caregivers’ and Health-Care Professionals’ Estimates
2018
Background: Patient-reported outcomes are usually considered to be the gold standard assessment. However, for the assessment of quality of dying and death, ratings of informal caregivers (ICGs) or health-care professionals (HCPs) must be considered for ethical and methodological reasons. This article aims to present results of ICGs’ and HCPs’ estimates of the questionnaire, quality of dying and death (QoDD) on patients who died in PCUs and to compare the level of agreement of both ratings/raters. Methods: The parent validation study to this analysis assessed the ICG and HCP versions of the QoDD. Descriptive statistics are presented for each item in both versions. T tests for the estimation …
