There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of the study is to assess combining AF ablation, with AV node ablation and pacemaker implantation for patients suffering with 'irregular heartbeats' or atrial fibrillation. The study will last 13 months.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
Aromatherapy is a form of complementary medicine that uses scented materials known as essential oils for the purpose of affecting a person's health or mood. Although aromatherapy has been used in childbirth for centuries, there are no high-quality studies examining whether the treatment works. Methodology We would like to see if aromatherapy affects a woman's experience of childbirth by lowering associated anxiety and pain. Consenting participants will be randomly allocated to one of these groups: 1. Aromatherapy oils (e.g. clary sage, peppermint, lavender, frankincense) 2. Non-essential oil (baby oil) 3. Standard maternity care We will gather primary data, e.g. if she's been in labour before and her awareness of complementary medicine. We will also conduct the Spielberger State-Trait Anxiety Inventory with her, and provide her with the oil and swab if she is in groups 1 or 2 with instructions to keep the swab with the oil on it near to her. She can also put more oil on the swab as she requires. Postnatally, data will be collected from her notes regarding pain relief used, duration of labour, augmentation of labour, and any other medical interventions of note. We will also complete the anxiety scale with her once more. Before her discharge we ask the mother for any comments regarding her experience of the labour. The results from all three cohorts will then be compared. There will also be opportunity for the midwife to make any comments regarding his/her perception of the participant's labour. Finally we will hold a focus group with midwives regarding the practicalities for implementation of aromatherapy in maternity care
The purpose of this study is to assess chemoreflex gain on exercise.
We aim to test our method for measuring chemosensitivity (the ventilatory response to a change in carbon dioxide), which uses sinusoidal carbon dioxide stimuli. Hypotheses: - Carbon dioxide sensitivity is dependent on the cycle time over which we administer the gas (frequency). - Chemoreflex gain decreases as deadspace increases.
This study is designed to treat tumors in the liver that cannot be removed surgically and chemotherapy cannot control these tumors, using radiation therapy and a more precise delivery than has been used before.
Consumption of a low glycemic index (GI) diet has been shown to improve glycaemic control in type 2 diabetics(Brand−Miller et al., 2003; Jenkins et al., 2008). In addition to the benefits for glycaemic control there is some evidence for acute improvements in cognitive performance after consumption of low GI foods compared with high GI foods in both adults (Benton et al., 2003; Kaplan et al., 2000) and adolescents (Ingwersen et al., 2007; Smith and Foster, 2008). Given these findings it is possible that low GI focused dietary interventions designed to improve glycaemic control and health outcomes for diabetic patients could also improve the cognitive function of these patients. This is of particular relevance in light of the evidence associating type 2 diabetes with cognitive decrements (Awad et al., 2004; Stewart and Loilitsa 1999; van Harten et al., 2006). To date two studies with type 2 diabetics have reported that a low GI breakfast was associated with increased verbal memory performance compared to a high GI breakfast (Greenwood et al., 2003; Papanikolaou et al. 2006). Further research should investigate the benefit of low GI foods to cognition. The aim of this study is to examine the effects of high and low glycaemic index breakfast on cognitive performance in adults with type 2 diabetes. Participants will perform a battery of cognitive tests after consuming 3 different breakfasts (high GI, low GI, and water) on 3 different tests days. The participants will be recruited from the general public and from the Leeds Teaching Hospital diabetes clinic. This research can benefit the development of specific dietary behaviours aimed at reducing diabetes related cognitive decline. This research is part of a PhD funded by the Economic and Social Research Council and the University of Leeds.
The purpose of this study is determine whether a specialised mood disorder service, which offers tailored psychological and pharmacological treatment, is more effective in the treatment of chronic unipolar depressive disorder then treatment as usual.
Children and adolescents with chronic kidney disease (CKD) are at high risk for cardiovascular (CV) morbidity and mortality. Recent studies suggest that pediatric patients with even moderately impaired kidney function may be afflicted with significant early cardiac and vascular abnormalities. The pathogenesis and the natural course of CV comorbidity in pediatric CKD patients is still elusive. In this multicenter, prospective, observational study the prevalence, degree and progression of CV comorbidity in children will be characterized and related to CKD progression. The morphology and function of the heart and vessels will be monitored by sensitive, non-invasive methods and will be compared with aged matched healthy controls. Multiple potential clinical, anthropometric, biochemical, and pharmacological risk factors will be monitored prospectively and will be related to CV status. Genotyping might identify predisposing genetic factors for progression of CV comorbidity and underlying nephropathies.
