Exocrine Pancreatic Function and Fat Malabsorption in Human Immunodeficiency Virus-Infected Patients
1999
BACKGROUND: Nutrients malabsorption frequently occurs in human immunodeficiency virus (HIV)-infected patients, but very few studies have investigated exocrine pancreatic digestive capacity in these patients. We therefore evaluated the frequency of exocrine pancreatic impairment and its eventual relation with fat malabsorption in HIV-infected patients. METHODS: Thirty-five HIV-infected patients (30 male, 5 female: mean age +/- standard deviation, 33.6 +/- 7.2 years) and 51 sex- and age-matched controls without gastroenterologic diseases were studied. In all subjects fecal elastase 1 (EL-1) was assayed, and fecal fat excretion was evaluated with the steatocrit test. RESULTS: Nineteen of 35 (5…
Helicobacter pylori infection does not affect the early rebleeding rate in patients with peptic ulcer bleeding after successful endoscopic hemostasis…
2003
Background and study aims Eradication of Helicobacter pylori infection can reduce the rebleeding rate of peptic ulcer bleeding in the long term. There are few data on the influence of H. pylori on the rebleeding rate in the acute phase of bleeding however. We therefore prospectively investigated the influence of H. pylori infection on the early rebleeding rate in patients who had undergone successful endoscopic hemostasis treatment for peptic ulcer bleeding. Patients and methods Between January 1996 and November 2000 all patients with peptic ulcer bleeding were evaluated consecutively. The diagnosis of H. pylori infection was made at index endoscopy, using histology and the rapid urease tes…
Changes in muscle activity with increasing running speed.
2005
Electromyographic (EMG) activity of the leg muscles and the ground reaction forces were recorded in 17 elite male middle-distance runners, who performed isometric maximal voluntary contractions (MVC) as well as running at different speeds. Electromyograms were recorded from the gluteus maximus, vastus lateralis, biceps femoris, gastrocnemius and tibialis anterior. The results indicated that the averaged EMG (aEMG) activities of all the muscles studied increased (P < 0.05) with increasing running speed, especially in the pre-contact and braking phases. At higher speeds, the aEMG activities of the gastrocnemius, vastus lateralis, biceps femoris and gluteus maximus exceeded 100% MVC in these s…
Retracted: Do patients profit from physostigmine in recovery from desflurane anaesthesia?
2007
Background: Physostigmine is the drug of choice in the central anticholinergic syndrome, but has also been used in post-operative mental derangement secondary to sedatives and volatile anaesthetics. The aim of this double-blind, randomized, prospective study was to determine whether physostigmine alters recovery after desflurane anaesthesia. Methods: One hundred patients undergoing urologic or surgical procedures were enrolled to receive either NaCl 0.9% (n= 50) or 2 mg of physostigmine (n= 50) at the end of general anaesthesia with propofol, fentanyl, cisatracurium and desflurane. Times to extubation, stating name, birthday and place of residence, and obeying commands such as eye opening…
Barriers to physical activity in coronary artery disease patients: Development and validation of a new scale
2017
Abstract Objective To develop and validate a self-report questionnaire to measure barriers to regular physical activity (PA) in patients with stable coronary artery disease (CAD). Methods Phase 1: 17 patients completed a semi-structured interview. After grouping and reformulating the reported barriers, their pertinence was reevaluated by the patients. Then, a decision algorithm was used to select items. A principal component analysis was performed to determine content validity. Phase 2: 49 patients completed the questionnaire resulting from phase 1 twice, 7 days apart, and questionnaires to evaluate depression, anxiety, and the level of physical activity. Construct validity was evaluated by…
A reanalysis of the center for epidemiological studies depression scale (CES-D) using non-parametric item response theory
2020
Abstract The “Center for Epidemiological Studies Depression Scale” (CES-D; Radloff, 1977 ) is a questionnaire used world-wide to measure depressive symptoms. Although the original four-factor-structure has been widely accepted and replicated, some studies point to other factor-structures like a one- and two-factor-structure. The goal of the current study was to evaluate the factor structure of the CES-D (one-, two- and four-factor-structure), which was found using classical test theory (CTT), with two non-parametric item-response-theory-models (Mokken-Scaling; Monotone-homogeneity-model; MHM and Double-monotonicity-model; DMM). To this end, a representative German sample was analyzed (N = 2…
Attitude towards adherence in patients with schizophrenia at discharge
2009
Abstract Background Purpose of the present study was to assess the attitude towards adherence at discharge and to verify its predictability using anamnestic and sociodemographic variables, factors influencing clinical treatment as well as the medical treatment applied. Methods Attitude towards adherence was evaluated in 369 inpatients with schizophrenic spectrum disorders within a naturalistic multicenter trial using the Compliance Rating Scale (CRS) by Kemp. Biweekly ratings of the PANSS, UKU and the Subjective Well-being under Neuroleptic Treatment Scale (SWN-K) were applied. Logistic regression and CART analyses were used to determine significant predictor variables for the attitude towa…
Saliva variations in gastro-oesophageal reflux disease.
2007
Abstract Objectives The protective role of saliva in the case of oesophageal exposition to gastric acid has long been studied but some contradictions still remain. The main end-point of this study was to evaluate if a qualitative and quantitative alteration in salivary secretion exists in patients affected by GERD. Methods One hundred and twenty patients (T group) with clinically and endoscopically diagnosed GERD, and 98 healthy subjects (C group) have been evaluated; salivary tests (i.e. basal flow rate, stimulated flow rate, pH, [Na + ] and [K + ]) were performed, socio-demographical variables and oral GERD-related symptoms were taken into account. SPSS 10.5 software was used for statisti…
An adaptive display for the treatment of diverse trauma PTSD victims.
2009
El trastorno de estrés postraumático (TEPT) puede desarrollarse después de la exposición a un evento aterrador. Las personas que sufren de trastorno de estrés postraumático presentan hiperactividad y evitación, y experimentan síntomas que provocan angustia y deterioro en áreas de vida significativas. Los programas de comportamiento cognitivo, incluida la terapia de exposición, son actualmente el tratamiento de elección para el TEPT. Aunque estos programas son eficaces, hay margen de mejora; La utilización de la terapia de exposición por los médicos es baja y las tasas de desgaste son altas. La aplicación de nuevas tecnologías, especialmente la realidad virtual (VR), podría ayudar a superar …
Sudomotor testing predicts the presence of neutralizing botulinum A toxin antibodies.
2002
The increasing number of patients being treated with botulinum toxin A complex (BoNT/A) has led to a higher incidence of neutralizing anti-BoNT/A antibodies (ABAs). Because BoNT/A is known to inhibit sweating, here we report sudometry as a possibility for predicting the presence of ABA. Sixteen patients suffering from spasmodic torticollis were selected: in 2 patients, BoNT/A treatment continued to be effective, in 9 patients, the treatment effect was impaired, and in 5 patients, secondary treatment failure developed. BoNT/A (100 mouse units, Dysport; Ipsen Pharma, Berkshire, United Kingdom) was injected subcutaneously into the lateral calves. Sweating was visualized with iodine starch stai…
