Filter by:Benign prostate obstruction (BPO) can be treated with a range of laser treatments using different laser systems and applications. Transurethral laser treatment is considered to be an alternative treatment to transurethral resection of the prostate (TURP). The latest guidelines of the European Association of Urology recommend 532-nm GreenLight laser vaporisation of the prostate and thulium laser enucleation as alternatives to TURP. For further investigation of the efficacy of GreenLight and thulium laser in treating BPH, the investigators organize a prospective randomised control study. The investigators will enrol 100 patients with BPO, treated with either GreenLight laser or thulium laser prostatectomy, and compare their safety and efficacy.
Aortic stenosis (AS) is the most frequent valvular heart disease in Western countries, with increasing prevalence. Recent guidelines recommend aortic valve intervention (surgical aortic valve replacement [SAVR] or transcatheter aortic valve replacement [TAVR]) in severe AS, as soon as symptoms or left ventricular (LV) dysfunction occur, in order to improve clinical outcome and achieve LV mass (LVM) regression. The highest amount of LVM regression is obtained during the first year. Nevertheless, there is heterogeneity in LV remodeling and residual LV hypertrophy is associated with poorer postoperative improvement in cardiac function and morphology. Incomplete regression of LV hypertrophy at 12 months after SAVR is a powerful predictor of adverse outcome. Yet, the use of specific pharmacological therapy to improve postoperative LVM regression could be an appealing therapeutic option after aortic valve intervention. Renin-angiotensin-aldosterone system blockers (RAASb) and more particularly angiotensin-II receptor blockers (ARBs) are efficient in reducing LVM in hypertensive patients, as emphasized by several meta-analyses. In addition, ARBs improve myocardial relaxation, diastolic function, decreased hypertrophy and may have anti-fibrotic effects. In a recent retrospective study from our group, RAASb prescription after SAVR was associated with increased survival, but confirmation through a randomized trial is mandatory. In a prospective randomized single-center study, the use of candesartan was associated both with LV and LA remodeling as compared to the conventional management. Nevertheless, these results are based on echocardiographic data, which is not the gold standard for the assessment cardiac remodeling, and no placebo or active comparator was tested to control the impact of ARBs in these patients. The primary objective of this Phase II study is to investigate the efficacy of valsartan, introduced postoperatively, as compared to placebo, on 1-year changes in indexed LVM, as assessed by CMR, in patients undergoing aortic valve intervention (SAVR or TAVR) for AS. The secondary objectives are to compare the efficacy of valsartan vs. placebo in terms of one-year changes (difference from baseline) in cardiac function and in cardiac morphology, one-year exercise capacity and one-year changes in biomarkers related to cardiac function. In addition, the assessment of the safety of valsartan will also be considered as secondary objective. The ARISTOTE trial is a multicenter prospective phase II, randomized, double-blind study including patients with the diagnosis of severe AS and indication for valve intervention. The active treatment is valsartan, an orally active, potent, and specific angiotensin II receptor antagonist. Patients will be randomized between 2 groups (valsartan versus placebo) and the treatment will be initiated (80 mg daily) at 5±4 days following aortic valve intervention. The comparative treatment will be a placebo; tablets of valsartan and placebo have a similar appearance and administration mode. Patient in the control group will receive a placebo using the same protocol as the valsartan group. The patients will be cautiously monitored and any adverse events will be collected. The dose will be increased at 160 mg daily 13±2 days after aortic valve intervention and, if well tolerated, for the remaining period of the study. The tolerance will be regularly assessed and dose adjusted according to a pre-specified algorithm.
The purpose of this pivotal investigation is to evaluate the efficacy and safety of the Cutera enlighten multi-wavelength 532 nm and 1064 nm Nd:YAG picosecond pulse duration laser and an investigational micro-lens array (MLA) handpiece attachment for improvement of acne scars.
The overall rationale is to reduce the risk of sudden cardiac death in individuals with hypertrophic cardiomyopathy (HCM). The novel approach of this study is to correlate Positron Emission Tomography (PET) findings to ventricular arrhythmias detected by the implantable cardioverter defibrillator (ICD). This could potentially lead to an improved risk stratification of HCM patients.
Differentiating hypertrophic cardiomyopathy (HCM) from hypertensive heart disease (HHD) unavoidably encounters diagnostic challenges especially in patient of suspected HCM with history of hypertension. Diverse and overlapping forms of HCM can often lead to ambiguity when diagnosis is based on a single genetic or morphological index. The investigators have deduced a integrated formula based on cardiac magnetic resonance (CMR) imaging and established a differentiating flow-chart between HCM and HHD, the investigators aim to identify their method in the current multi-center trial.
Hypertrophic cardiomyopathy (HCM) is associated with sudden cardiac death and an increased risk of atrial fibrillation and subsequent embolic event. An insertable cardiac monitor will provide data on cardiac rhythm over a period of 18 months. This will provide an extended monitoring far longer than 24-48 hours of Holter monitoring as is currently usual care. Therefore, detection of arrhythmias could be used in risk stratification and decision-making with regard to offer an implantable defibrillator and anticoagulants.
Inorganic nitrate, which is found at high levels in green leafy vegetables, is reduced to nitrite by bacteria in the mouth, swallowed, and absorbed in the stomach into the blood. Studies have shown that increasing the blood levels of nitrite improves the way that muscles use oxygen and energy during exercise, and potentially blood flow. Some people (~1 in 500) suffer from a type of genetic heart condition known as hypertrophic cardiomyopathy (HCM). This condition means that the muscle in the heart does not use energy well and becomes larger than average, meaning that they have to tap into the heart's 'energy reserves'. It is not known if nitrite has the same beneficial effects on heart muscle as on other muscles in the body. Our study will explore the mechanism by which nitrite may improve the function and energy status of the heart in HCM.
Clinical research question: Can OM-85 reduce the recurrence of respiratory tract infections (RTIs) in children with AH by stimulating the immunological response of the host and therefore, as a consequence reduce the size of adenoid tissue in children with adenoid hypertrophy? Can this prevent further complications such as surgery need? Half of participants will receive OM-85, while other half will receive a placebo.
This is a randomized, controlled, within-patient, single-blinded, pilot study that will evaluate the impact of laser treatment on burn HSc relative to self-matched control scars. The studied primary outcomes of treatment are scar pliability, thickness, vascularity, pain, itch and patient satisfaction.
