Increasing physical activity through an Internet-based motivational intervention supported by pedometers in a sample of sedentary students: A randomi…
2017
The aim of this study was to analyse the effect of an Internet-based motivational intervention (IMI) supported by pedometers (in comparison with IMI alone and non-intervention) on increasing daily steps and changing constructs related to physical activity (PA) in a sample of sedentary students.A randomised-controlled trial was conducted with 76 sedentary or low-active college students. The purpose of the IMI was to deliver information to increase motivation and set individualised PA goals. It involved a 3-week intervention and a 3-months follow-up.Objective measures were used to measure daily steps, and self-report questionnaires to assess different constructs related to PA.Results revealed…
Mepolizumab for severe eosinophilic asthma (DREAM): a multicentre, double-blind, placebo-controlled trial
2012
BACKGROUND: Some patients with severe asthma have recurrent asthma exacerbations associated with eosinophilic airway inflammation. Early studies suggest that inhibition of eosinophilic airway inflammation with mepolizumab-a monoclonal antibody against interleukin 5-is associated with a reduced risk of exacerbations. We aimed to establish efficacy, safety, and patient characteristics associated with the response to mepolizumab. METHODS: We undertook a multicentre, double-blind, placebo-controlled trial at 81 centres in 13 countries between Nov 9, 2009, and Dec 5, 2011. Eligible patients were aged 12-74 years, had a history of recurrent severe asthma exacerbations, and had signs of eosinophil…
Repetitive low-energy shock wave treatment for chronic lateral epicondylitis in tennis players.
2004
Background There is conflicting evidence regarding extracorporeal shock wave treatment for chronic tennis elbow. Hypothesis Treatment with repetitive low-energy extracorporeal shock wave treatment is superior to repetitive placebo extracorporeal shock wave treatment. Methods Seventy-eight patients enrolled in a placebo-controlled trial. All patients were tennis players with recalcitrant MRIconfirmed tennis elbow of at least 12 months’ duration. Patients were randomly assigned to receive either active low-energy extracorporeal shock wave treatment given weekly for 3 weeks (treatment group 1) or an identical placebo extracorporeal shock wave treatment (sham group 2). Main outcome measure was …
An internet-based self-administered intervention for promoting healthy habits and weight loss in hypertensive people who are overweight or obese: a r…
2015
Background The prevalence of overweight and obesity is on the rise worldwide with severe physical and psychosocial consequences. One of the most dangerous is hypertension. Lifestyle changes related to eating behaviour and physical activity are the critical components in the prevention and treatment of hypertension and obesity. Data indicates that the usual procedures to promote these healthy habits in health services are either insufficient or not efficient enough. Internet has been shown to be an effective tool for the implementation of lifestyle interventions based on this type of problem. This study aims to assess the efficacy of a totally self-administered online intervention programme …
The relevance of uniform reporting in oral leukoplakia: Definition, certainty factor and staging based on experience with 275 patients
2012
The aim of the present study was to evaluate the definition of oral leukoplakia, proposed by the WHO in 2005 and taking into account a previously reported classification and staging system, including the use of a Certainty factor of four levels with which the diagnosis of leukoplakia can be established. In the period 1997-2012 a hospital-based population of 275 consecutive patients with a provisional diagnosis of oral leukoplakia has been examined. In only 176 patients of these 275 patients a firm diagnosis of leukoplakia has been established based on strict clinicopathological criteria. The 176 patients have subsequently been staged using a classification and staging system based on size a…
Sequential alternating deferiprone and deferoxamine treatment compared to deferiprone monotherapy: main findings and clinical follow-up of a large mu…
2011
In β-thalassemia major (β-TM) patients, iron chelation therapy is mandatory to reduce iron overload secondary to transfusions. Recommended first line treatment is deferoxamine (DFO) from the age of 2 and second line treatment after the age of 6 is deferiprone (L1). A multicenter randomized open-label trial was designed to assess the effectiveness of long-term alternating sequential L1-DFO versus L1 alone iron chelation therapy in β-TM patients. Deferiprone 75 mg/kg 4 days/week and DFO 50 mg/kg/day for 3 days/week was compared with L1 alone 75 mg/kg 7 days/week during 5-year follow-up. A total of 213 thalassemia patients were randomized and underwent intention-to-treat analysis. Statisticall…
Confirming the mechanisms behind cognitive-behavioural therapy effectiveness in chronic pain using structural equation modeling in a sample of patien…
2016
Objective To evaluate whether therapeutic mechanisms assumed to explain the effect of cognitive behavioural therapy (CBT) concerning temporomandibular symptoms are confirmed by structural equation modelling. Method Patients were randomly assigned to either an experimental group receiving CBT (N = 41) or a standard therapy control group (N = 31). Subjects were assessed before and after intervention using mediator variables hypothesized according to the CBT model, as well as outcome variables and other socio-demographic and clinical measures. Results The results confirm that the effect of treatment on pain intensity was partially mediated by distress, catastrophizing, perceived control, distr…
Acetic acid-guided biopsies after magnifying endoscopy compared with random biopsies in the detection of Barrett's esophagus: a prospective randomize…
2006
Background In contrast to standard video endoscopy, magnifying endoscopy after local acetic acid application enables recognition of mucosal surface architecture. Objective To investigate the diagnostic yield of magnifying endoscopy with acetic acid–targeted biopsies compared to random, 4-quadrant biopsies. Design Prospective randomized trial (ratio 1:1) with crossover design. Setting Two referral hospitals in Germany. Patients Thirty-one patients with Barrett's esophagus or visible columnar-lined lower esophagus. Interventions Patients were randomized to undergo either standard video endoscopy with 4-quadrant biopsies or magnifying endoscopy in conjunction with acetic acid application. All …
Effect of omalizumab on angioedema in H1-antihistamine-resistant chronic spontaneous urticaria patients: results from X-ACT, a randomized controlled …
2016
Background Chronic spontaneous urticaria (CSU) severely impacts quality of life (QoL), especially in patients with wheals and angioedema. Omalizumab is approved as add-on therapy for CSU patients; however, its effect on patients who are double-positive for wheals and angioedema has not been systematically studied. Objective The primary objective was to evaluate the efficacy of omalizumab vs placebo at week 28 using the Chronic Urticaria Quality of Life (CU-Q2oL) questionnaire. Number of angioedema-burdened days, time interval between successive angioedema episodes, disease activity, angioedema-specific and overall QoL impairment were secondary objectives. Methods X-ACT was a phase III, rand…
Efficacy and safety of omalizumab in patients with chronic urticaria who exhibit IgE against thyroperoxidase
2011
Background A subgroup of patients with chronic spontaneous urticaria (CU) exhibits IgE antibodies directed against autoantigens, such as thyroperoxidase (TPO). We conducted this study to investigate whether such patients with CU with IgE against TPO benefit from treatment with omalizumab, a humanized anti-IgE mAb licensed for the treatment of severe persistent allergic (IgE-mediated) asthma. Objectives We sought to assess the efficacy of omalizumab treatment in patients with CU with IgE autoantibodies against TPO. Methods In this multicenter, randomized, double-blind, placebo-controlled study patients with CU (male/female, 18-70 years of age) with IgE autoantibodies against TPO who had pers…
