Computerized acoustic voice analysis and subjective scaled evaluation of the voice can avoid the need for laryngoscopy after thyroid surgery.
2008
Because of frequent postoperative alterations in voice, many surgeons include laryngoscopy as a routine examination before/after thyroid surgery. The aim of this work was to determine whether more comfortable and easier subjective or objective postoperative voice assessments could complement or replace laryngoscopy.Sixty-four consecutive patients scheduled to undergo thyroid surgery underwent preoperative objective computerized acoustic voice analysis (CAVA), subjective scaled evaluation of the voice (SSEV) with the GIRBAS scale, and fiberoptic laryngoscopy. All patients had 7- and 30-day postoperative follow-up assessments using the same tests.CAVA measurements of jitter and noise-to-harmo…
Body Composition and Fitness during Strength and/or Endurance Training in Older Men
2008
PURPOSE: This study examined adaptations in body composition and physical fitness during a 21-wk strength and/or endurance training period in 40- to 65-yr-old men. We also compared the usefulness of different methods for the analysis of body composition to detect training-induced adaptations. METHODS: Fifty-three men were randomized into the endurance training (E: N = 14), strength training (S: N = 13), combined strength and endurance training (SE: N = 15), or control (C: N = 11) groups. S and E trained 2 and SE 2 x 2 times a week for strength and endurance. RESULTS: Percentage of fat (fat%) decreased (5-8%) similarly in all training groups. Fat% measured by DXA at baseline and its change c…
Design and validation of a patient-reported outcome measure scale in acute pancreatitis: the PAN-PROMISE study
2021
ObjectiveThis study aimed to develop and validate a patient-reported outcome measure (PROM) in acute pancreatitis (AP) as an endpoint centred on the patient.DesignA PROM instrument (PAtieNt-rePoRted OutcoMe scale in acute pancreatItis, an international proSpEctive cohort study, PAN-PROMISE scale) was designed based on the opinion of patients, professionals and an expert panel. The scale was validated in an international multicentre prospective cohort study, describing the severity of AP and quality of life at 15 days after discharge as the main variables for validation. The COSMIN (COnsensus-based Standards for the selection of health status Measurement INstruments) methodology was applied.…
Clinical evaluation of a wireless ECG sensor system for arrhythmia diagnostic purposes
2013
Accepted version of an article in the journal: Medical Engineering and Physics. Also available from the publisher at: http://dx.doi.org/10.1016/j.medengphy.2013.03.002 In a clinical study, a novel wireless electrocardiogram (ECG) recorder has been evaluated with regard to its ability to perform arrhythmia diagnostics. As the ECG recorder will detect a "non-standard" ECG signal, it has been necessary to compare those signals to "standard" ECG recording signals in order to evaluate the arrhythmia detection ability of the new system. Simultaneous recording of ECG signals from both the new wireless ECG recorder and a conventional Holter recorder was compared by two independent cardiology specia…
Two-dimensional echocardiographic evaluation of left ventricular ejection fraction by the ellipsoid single-plane algorithm: a reliable method for ass…
1995
The reliability of two-dimensional (2D) echocardiographic estimation of left ventricular ejection fraction (EF) is commonly recognized, but no satisfactory data are available about the accuracy of low or very low EF values determined by 2D echocardiography (ECHO-EF). The purpose of our study was to assess the reliability of low ECHO-EF values obtained using a simple time-economical algorithm such as the ellipsoid single-plane area-length method. Radionuclide angiography (RAD-EF) was taken as the standard of comparison. We studied 59 consecutive patients (31 women and 28 men) referred to our echocardiographic laboratory. Both 2D echocardiography and radionuclide angiography were blindly perf…
Development and validation of the Migraine Screen Questionnaire (MS-Q).
2005
Aim.—To develop and evaluate the clinimetric properties of a new migraine screening questionnaire: the Migraine Screen Questionnaire (MS-Q). Background.—Migraine is a public health problem requiring screening programs and tools to ensure early detection. Methods.—A questionnaire was developed based on the criteria of the International Headache Society (IHS) and a review of the literature by a committee of experts. Stage I: The original version of the MS-Q was distributed by mail and completed by Pfizer employees and self-administered to neurological patients; all subjects were afterward evaluated by a neurologist who was blinded to the MS-Q results, to establish an independent IHS diagnosis…
Standardized T2* map of normal human heart in vivo to correct T2* segmental artefacts.
2007
A segmental, multislice, multi-echo T2* MRI approach could be useful in heart iron-overloaded patients to account for heterogeneous iron distribution, demonstrated by histological studies. However, segmental T2* assessment in heart can be affected by the presence of geometrical and susceptibility artefacts, which can act on different segments in different ways. The aim of this study was to assess T2* value distribution in the left ventricle and to develop a correction procedure to compensate for artefactual variations in segmental analysis. MRI was performed in four groups of 22 subjects each: healthy subjects (I), controls (II) (thalassemia intermedia patients without iron overload), thala…
An examination of the psychometric structure of the Multidimensional Pain Inventory in temporomandibular disorder patients: a confirmatory factor ana…
2006
Abstract Background This paper seeks to analyse the psychometric and structural properties of the Multidimensional Pain Inventory (MPI) in a sample of temporomandibular disorder patients. Methods The internal consistency of the scales was obtained. Confirmatory Factor Analysis was carried out to test the MPI structure section by section in a sample of 114 temporomandibular disorder patients. Results Nearly all scales obtained good reliability indexes. The original structure could not be totally confirmed. However, with a few adjustments we obtained a satisfactory structural model of the MPI which was slightly different from the original: certain items and the Self control scale were elimina…
Implicit and explicit self-concept of neuroticism in borderline personality disorder
2019
In the past, research on personality in borderline personality disorder (BPD) used primarily questionnaires suggesting heightened neuroticism in BPD. Self-report instruments inform about the conscious or explicit self-concept. BPD patients are known to show negative distortion with exaggeration of negative affect in the self-report. Neuroticism represents a risk factor for mental disorders. Indirect measures are available that tap into the implicit self-concept of neuroticism. The implicit self-concept refers to individual differences in associative representations of the self. The present study examined for the first time the implicit in addition to the explicit self-concept of neuroticism…
Covariation of spectral and nonlinear EEG measures with alpha biofeedback.
2002
Item does not contain fulltext This study investigated how different spectral and nonlinear EEG measures covaried with alpha power during auditory alpha biofeedback training, performed by 13 healthy subjects. We found a significant positive correlation of alpha power with the largest Lyapunov-exponent, pointing to an increased dynamical instability of the EEG accompanying alpha enhancement. Alpha power amplification, moreover, was significantly correlated with a decrease of spectral entropy within the alpha range. This outcome reflects a sharpening of the alpha peak during biofeedback training. The fact that the sharpening effect clearly preceded the increase of alpha amplitude could be exp…
