Influence of Patient Selection on the Outcome of Capsule Endoscopy in Patients With Chronic Gastrointestinal Bleeding
2005
Background: In chronic gastrointestinal bleeding, success rates in the range of 48% to 76% have been reported for diagnosing clear bleeding sources using capsule endoscopy. The influence of patient selection on the numbers of positive findings yielded by capsule endoscopy is as yet unclear. Methods: From April 2001 to June 2003, capsule endoscopy was carried out in 74 of a total of 127 patients (58%) who presented for capsule endoscopy with a high suspicion of gastrointestinal bleeding in the small-bowel region. Seventy of the 74 patients were included in the analysis. This group of patients was divided into a study group (32 patients) and a post-study group (38 patients), and the two group…
Screening for generalized anxiety disorder in Spanish primary care centers with the GAD-7.
2017
The aim of the study was to determine the criterion validity of a computerized version of the General Anxiety Disorder-7 (GAD-7) questionnaire to detect general anxiety disorder in Spanish primary care centers. A total of 178 patients completed the GAD-7 and were administered the Composite International Diagnostic Interview (CIDI) for DSM-IV Axis I Disorders, which was used as a reference standard. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were calculated. A cut-off of 10 yielded a sensitivity of .87, a specificity of .78, a positive predictive value of .93, a negative predictive value of .64, a positive likelihood ratio o…
Development and validation of the EUROLIGHT questionnaire to evaluate the burden of primary headache disorders in Europe
2010
We developed a 103-item self-reporting questionnaire to assess the burden of primary headache disorders on those affected by them, including headache characteristics, associated disability, co-morbidities, disease-management and quality of life. We validated the questionnaire in five languages with 426 participants (131 in UK, 60 in Italy, 107 in Spain, 83 in Germany/Austria, and 45 in France). After a linguistic and a face-content validation, we tested the questionnaire for comprehensibility, internal consistency and test–retest reliability at an interval of one month. In the different countries, response rates were between 73% and 100%. Test–retest reliability varied between –0.27 to 1.0…
Spanish Version of the Knowledge and Attitudes Survey Regarding Pain.
2019
A variety of valid tools are available to assess staff knowledge and attitudes regarding pain, among which is the Knowledge and Attitudes Survey Regarding Pain. Although this instrument has been widely and successfully used, a valid and adapted Spanish version is yet to be developed. The purpose of this study was to validate the Spanish version of the Knowledge and Attitudes Survey Regarding Pain. After translating and back-translating this tool, we conducted a cross-cultural adaptation and construct validation with 102 participants, including nursing professionals (in palliative care, oncology, and intensive care) from five health centers and final-year nursing students. All participants w…
Causal symptom attributions in somatoform disorder and chronic pain.
2009
Abstract Objective Somatoform disorders (SFD) are defined by symptoms that lack medical explanation. This study examined the type and pattern of patients' causal attributions using a new semistructured interview technique Methods The Causal Attributions Interview allows to assess and weigh 15 common explanations of physical symptoms. Attributions given by 79 patients with SFD were compared with those obtained from 187 chronic pain patients. Results The test–retest reliabilities of the interview-elicited attributions were satisfactory to good. SFD patients attributed most of their symptoms to mental/emotional problems (46.9%) and somatic disease (41.1%), while the pain sample preferred physi…
Left ventricular Myocardial dysfunction in arrhythmogenic cardiomyopathy with left ventricular involvement: A door to improving diagnosis.
2018
[EN] Background: Diagnostic Task Force Criteria (TFC) for arrhythmogenic cardiomyopathy (AC) exhibit poor performance for left dominant forms. TFC only include right ventricular (RV) dysfunction (akinesia, dyssynchrony, volumes and ejection fraction). Moreover, cardiac magnetic resonance imaging (CMRI) assessment of left ventricular (LV) dyssynchrony has hitherto not been described. Thus, we aimed to comprehensively characterize LVCMRI behavior in AC patients. Methods: Thirty-five AC patients with LV involvement and twenty-three non-affected family members (controls) were enrolled. Feature-tracking analysis was applied to cine CMRI to assess LV ejection fraction (LVEF), LV end-systolic and …
Five times sit-to-stand test in subjects with total knee replacement: Reliability and relationship with functional mobility tests
2017
The objective was to determine the inter-observer and test/retest reliability of the "Five-repetition sit-to-stand" (5STS) test in patients with total knee replacement (TKR). To explore correlation between 5STS and two mobility tests. A reliability study was conducted among 24 (mean age 72.13, S.D. 10.67; 50% were women) outpatients with TKR. They were recruited from a traumatology unit of a public hospital via convenience sampling. A physiotherapist and trauma physician assessed each patient at the same time. The same physiotherapist realized a 5STS second measurement 45-60min after the first one. Reliability was assessed with intraclass correlation coefficients (ICCs) and Bland-Altman plo…
Do Intensity Ratings and Skin Conductance Responses Reliably Discriminate Between Different Stimulus Intensities in Experimentally Induced Pain?
2010
Abstract The present study addresses the question whether pain-intensity ratings and skin conductance responses (SCRs) are able to detect different intensities of phasic painful stimuli and to determine the reliability of this discrimination. For this purpose, 42 healthy participants of both genders were assigned to either electrical, mechanical, or laser heat-pain stimulation (each n = 14). A whole range of single brief painful stimuli were delivered on the right volar forearm of the dominant hand in a randomized order. Pain-intensity ratings and SCRs were analyzed. Using generalizability theory, individual and gender differences were the main contributors to the variability of both intens…
Technical note: a comparison of central and peripheral intraocular pressure using rebound tonometry
2007
Purpose: To compare central and peripheral intraocular pressure (IOP) readings obtained with rebound tonometry.Methods: Intraocular pressure was measured on the right eye of 153 patients (65 males, 88 females), aged from 21 to 85 years (mean +/- S.D., 55.5 +/- 15.2 years) with the ICare rebound tonometer at centre, and 2 mm from the limbus (in the nasal and temporal regions along the 0-180O corneal meridian).Results: Intraocular pressure values obtained with the ICare were 14.9 +/- 2.8; 14.1 +/- 2.5 and 14.5 +/- 2.7 mmHg at centre, nasal and temporal corneal locations, respectively. On average, nasal and temporal IOP readings were 0.75 and 0.37 mmHg lower than the central reading (p 0.05, r…
Role of high-resolution ultrasonography without and with real-time spatial compound imaging in evaluating the injured posterior cruciate ligament: pr…
2009
This study sought to compare high-resolution ultrasonography (HRUS) without and with compound imaging in evaluating the injured posterior cruciate ligament (PCL). Thirteen patients with a magnetic resonance imaging (MRI) diagnosis of PCL lesions (ten acute and three chronic) and 20 healthy controls underwent conventional and compound HRUS performed by the same radiologist who was blinded to the subjects' case-control status. The PCL was scanned in a longitudinal direction in all cases. HRUS images were assessed for PCL thickness by two other radiologists blinded to the number and type of PCL injury. PCLs were classified as normal or injured, and the latter as having acute or chronic injurie…
