Switching to a Second Thiopurine in Adult and Elderly Patients With Inflammatory Bowel Disease: A Nationwide Study From the ENEIDA Registry
2020
Abstract Background and Aims Although commonly used in inflammatory bowel disease [IBD], thiopurines frequently cause intolerance, and switching to a second thiopurine has only been reported in some small series. Ours aims in this study were to evaluate the safety of switching to a second thiopurine in a large cohort, and to assess the impact of age on tolerance. Methods Adult IBD patients from the ENEIDA registry, who were switched to a second thiopurine due to adverse events [excluding malignancies and infections], were identified. At the beginning of thiopurine treatment, patients were divided by age into two groups: 18–50 and over 60 years of age. The rate and concordance of adverse eve…
Isokinetic elbow flexion and coactivation following eccentric training.
1999
The influence of an eccentric training on torque/angular velocity relationships and coactivation level during maximal voluntary isokinetic elbow flexion was examined. Seventeen subjects divided into two groups (Eccentric Group EG, n = 9 Control Group CG, n = 8) performed on an isokinetic dynamometer, before and after training, maximal isokinetic elbow flexions at eight angular velocities (from - 120 degrees s(-1) under eccentric conditions to 240 degrees s(-1) under concentric conditions), and held maximal and submaximal isometric actions. Under all conditions, the myoelectric activities (EMG) of the biceps and the triceps brachii muscles were recorded and quantified as the RMS value. Eccen…
Re-examination of training effects by electrostimulation in the human elbow musculoskeletal system.
2000
This study examines the effects of a 7 weeks sub-maximal training period of electrostimulation on the maximal isometric, concentric, eccentric voluntary torque and muscle contractile properties of the elbow flexor muscles of nine subjects. The daily program consisted of five series of six 6-s isometric actions (60 to 70% of maximal isometric voluntary action) at an elbow angle of 90 . After training the maximal voluntary isometric flexion torque increased significantly whereas the maximal voluntary isometric extension torque decreased significantly. Increases in isometric flexion torque were linked to an increase of the myoelectrical activity of the biceps brachii muscle. Under dynamic cond…
Acute effects of shock-type vibration transmitted to the hand-arm system.
1984
The aim of the project was to find out whether shock-type vibration of hand-tools compared to non-impulsive vibration has stronger acute effects on the hand-arm system and therefore needs a stricter evaluation from the occupational health point of view in comparison with the requirements of the Draft International Standard ISO-DIS 5349. Under laboratory conditions, subjects were exposed to simulated vibration of hand-tools (grinder, chain saw, hammer-drill, pneumatic hammer, rivet hammer and nailer). The following evaluation criteria were used: biomechanical transmissibility of the hand-arm system (wrist, elbow joint, shoulder joint); muscle-activity (m. flexor carpi ulnaris, m. biceps, m. …
A Web-Based Telemanagement System for Improving Disease Activity and Quality of Life in Patients With Complex Inflammatory Bowel Disease: Pilot Rando…
2018
Background: The reported efficacy of telemedicine in patients with inflammatory bowel disease (IBD) is inconsistent among studies, and data for complex IBD are lacking. Objective: We aimed to evaluate the impact of remote monitoring using a Web system—Telemonitorizacion de la Enfermedad de Crohn y Colitis Ulcerosa or Telemonitoring of Crohn’s Disease and Ulcerative Colitis (TECCU)—as compared to standard care and telephone care on health outcomes and health care in patients with complex IBD. Methods: We performed a 3-arm randomized controlled trial. Adult patients with IBD who received immunosuppressants and biological agents were recruited from the IBD Unit of a tertiary university hospita…
Increased expression of markers of early atherosclerosis in patients with inflammatory bowel disease.
2016
Recent studies documented an increased cardiovascular risk in patients with inflammatory bowel disease (IBD). Our study aimed at investigating the prevalence of intima-media thickness (IMT) of the carotid arteries and the arterial stiffness indices as markers of early atherosclerosis in young IBD patients.We recruited 68 consecutive IBD patients, and 38 matched healthy controls less than 45years old (median age 31.6±8.1years). Clinical and demographic features, cardiovascular risk factors, history of cardiovascular events, concomitant therapies were registered on a dedicate database. Carotid IMT was evaluated by using high resolution B-mode ultrasonography. Arterial stiffness was assessed b…
Genetic predisposition to thrombophilia in inflammatory bowel disease
2011
BACKGROUND Inflammatory bowel disease (IBD) is linked to a definite risk of thromboembolic events (TE), but data on the role of prothrombotic genetic mutations are conflicting. STUDY Fourteen genetic factors involved in TE pathogenesis were investigated in a homogeneous cohort of Sicilian patients with IBD with and without history of TE and in healthy controls. Forty IBD patients (21 CD, 19 UC) and 20 healthy individuals were enrolled. Genetic testing was based on the reverse hybridization principle by a commercial assay that analyzes 14 polymorphisms involved in thrombophilia and cholesterol metabolism. The rate of genetic polymorphisms and mutations was compared between IBD patients and h…
Aggressive Pharmacological Treatment for Reversing Malignant Bowel Obstruction
2004
Early and intensive pharmacological treatment not only may reduce gastrointestinal symptoms but also reverse malignant bowel obstruction. Fifteen consecutive advanced cancer patients with inoperable bowel obstruction received a combination of drugs including metoclopramide, octreotide, dexamethasone and an initial bolus of amidotrizoato. Recovery of intestinal transit was reported within 1-5 days in fourteen patients, who continued this treatment without presenting symptoms of bowel obstruction until death. This case series establishes that the combination of propulsive and antisecretive agents can act synergistically to allow a fast recovery of bowel transit without inducing unpleasant col…
Side-effects of extracorporeal shock wave therapy (ESWT) in the treatment of tennis elbow
2002
Apart from a few observational reports, there are no studies on the side-effects of extracorporeal shock wave therapy (ESWT) in the treatment of insertion tendopathies. Within the framework of a randomised, placebo-controlled, single-blind, multicentre study to test the effectiveness of ESWT in the case of lateral epicondylitis (LE), side-effects were systematically recorded. A total of 272 patients from 15 centres was allocated at random to active ESWT (3 x 2000 pulses, energy flux density ED(+) 0.04 to 0.22 mJ/mm(2) under local anaesthesia) or placebo ESWT. In all, 399 ESWT and 402 placebo treatments were analysed. More side-effects were documented in the ESWT group (OR = 4.3, CI = [2.9; …
Motor unit activation patterns during isometric, concentric and eccentric actions at different force levels.
2002
Motor unit activation patterns were studied during four different force levels of concentric and eccentric actions. Eight male subjects performed concentric and eccentric forearm flexions with the movement range from 100 degrees to 60 degrees in concentric and from 100 degrees to 140 degrees elbow angle in eccentric actions. The movements were started either from zero preactivation or with isometric preactivation of the force levels of 20, 40, 60 and 80% MVC. The subjects were then instructed to maintain the corresponding relative force levels during the dynamic actions. Intramuscular and surface EMG was recorded from biceps brachii muscle. Altogether 28 motoneuron pools were analyzed using…
