Filter by:Participants who have signed up to the Watford Football Club Community and Education Trust Weight management programme called Shape Up will be approached to see if they would like to take part in this research study. Their participation in the Shape Up programme will not be affected if they do not choose to opt in to the research component. Fifty participants will be recruited and randomised in to one of two groups. One group will be the control group and they will undertake the Shape Up programme as normal and will be asked to complete some questionnaires in week 1, week 12 and then at 12 weeks follow up. The intervention group will be asked to complete the same questionnaires and will also have a venous blood sample taken at week 1, 12 and then at 12 weeks follow up. This is for measures of cholesterol, sugar, vitamin D, vitamin B12 and iron. The participants will receive a report from a medical doctor in layman terms on these results a week later and will have access to their data on an online portal set up by Medichecks. The weight management programme is based on a behaviour change programme where the participants attend a 90-minute session for 12 weeks, and they are then supported for another 12 weeks following the end of the supervision. The participants have weight and BMI measured at week 1, 12 and 12 weeks follow up. Each session consists of an education component followed by an exercise component. Initially, the education part is longer and the exercise is shorter, but as the programme progresses the education part becomes shorter and the exercise longer. The education programme includes topics such as healthy eating, increased physical activity and stress. The exercise programme includes whole body activities such as circuit training as well as other group exercise such as football. The questionnaires will include The Treatment Self-Regulation Questionnaire which will identify the motivation behind the participants' health. A general health questionnaire which is a subjective measure of health (Euro qol EQ-5). The Mental Component Summary of the 12- item Short Form (SF12) which measures emotional quality of life. Physical activity will be measured through the short Active Lives Questionnaire. All these questionnaires have been attached as appendices. All participants will complete an exit telephone interview from the study to determine qualitative feedback on their experience of the study and to explore whether the biomarkers influenced their motivation to change their lifestyle. Some example questions have been attached. This is just a feasibility study, therefore no hypothesis testing will be undertaken.
Objectives: Alveolar resorption is one of the most important events in periodontitis. Osteoclast activity is regulated by the ratio between receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG). The aim of this study was to evaluate changes in the RANKL/OPG ratio in crevicular fluid after periodontal treatment. Material and methods: A total of 15 patients with periodontitis were included in the study group. Samples were collected from an area with active periodontitis and a healthy area. The RANKL and OPG levels were measured before and after periodontal scaling and root planing (SRP) treatment. The study group was compared to the control group, which included 10 patients without periodontitis.
The primary goal of this study is to investigate the qualitative and quantitative effects of scaling and root planing (SRP) with and without minocycline HCL microspheres, 1 mg on periodontal pathogens and overall bacterial load. A randomized controlled clinical trial of a control (SRP) group and an experimental (SRP with minocycline HCl microspheres, 1 mg) group is planned. Specific Aim 1: Evaluate the cumulative oral periodontal bacterial burden in both control and test groups over a six month period. Specific Aim 2: Assess gingival crevicular fluid (GCF) and serum biomarkers of inflammation.
The purpose of this study is to assess differential effects of T4 and T3 on cell and tissue level
Cigarette smoking is a habit that has spread all over the world and is a significant risk factor for many diseases including cardiovascular disease, chronic obstructive pulmonary disease(COPD),asthma and lung cancer. Evaluation and understanding of tobacco health effects are of major interest worldwide and answer to important societal concerns. Identification of new biomarkers of exposure to tobacco smoke potentially implicated in COPD or lung carcinogenesis would allow a better observation of tobacco exposed population, thanks to screening establishment at reversible stages of pathological processes. In this study, we question whether cigarettes smoking alters miRNA profiles of extracellular vesicles (EVs) present in human broncho alveolar lavages (BALs), which could affect surrounding normal bronchial epithelial cells status.
Acute high-risk abdominal surgery (AHA) is performed in hospitals worldwide. Ethiologies are heterogeneous, but it carries a high mortality rate (1)(2). In particular, emergency laparotomies performed on elderly people has a high mortality rate(3)(4). Different quality improvement programs have been suggested, but the quality of care and mortality varies between hospitals (5)(6). The use of postoperative intensive care seem to be inadequate for this high risk population (1)(7)(8). It is of paramount importance to identify the frailest and acutely deranged patients, who are in risk of poor outcome, to allocate resources for optimization postoperatively. Failure to escalate care intensity after having developed postoperative complications affect outcome. Organization, teamwork and culture is important postoperatively to be able to escalate care especially in standard care wards (9)(10). However, it is difficult to predict which patients will develop complications. Different risk assessment tools have been proposed for patients undergoing AHA (11)(12). The APACHE-II score, even though developed for critical care, seems to give the best prediction of outcome. Objective risk assessment tools support clinical decision making as subjective clinical assessment often underestimates the risk for the patients in highest risk of complications and death (13). Good clinical decision-making is likely to improve the clinical outcome by allocating appropriate resources. Prognostic tools are also useful to inform patients about what to expect in the postoperative phase and of long-term outcome. Especially in the elder population with increased risk of loss of function or independency, this can be useful to give informed consent to treatment. Furthermore, good risk assessment is important to optimize palliative care after end-of-life decisions, which is often ignored in research, but highly relevant in clinical work. Prognostic biomarkers in other high mortality populations have received much attention for risk stratification (14). An ideal biomarker should be readily available upon decision-making, easy to measure, and reliable. Furthermore, it should accurately differentiate prognosis for patients to have value in the clinical decision-making and guide the treatment. It should also be linked to the clinical outcomes. The investigators aim to identify AHA biomarkers that are prognostic or predictive for postoperative morbidity, mortality and length of hospitalization.
The intake of fruits and vegetables has been associated to a lower risk of developing metabolic diseases and cancer. The intake of tomato has been proposed to decrease the risk of prostate cancer while the high content of pro-vitamine A carotenes in banana have shown to alleviate Vitamin A deficiency in different countries. Interestingly in spite of their popularity, there are no biomarkers of banana intake reported in the literature while lycopene is the most frequently used metabolite to indicate tomato consumption however, its limited specificity and between-subjects variation sets doubt of its accuracy. Therefore, the identification of novel biomarkers for both banana and tomato is of great value. Untargeted metabolomics, allows a holistic analysis of the food metabolome allowing a deeper inquiry in the metabolism of different compounds and the recognition of patterns and individual differences that may lead to new hypothesis and further research. Therefore, the aim of the present study is to identify biomarkers of acute intake of banana and tomato using an untargeted approach on urine serum of 12 volunteers that participated in a crossover, randomized, controlled study. Volunteers consumed three different test foods: 1) 240g of banana, 2) 300g of tomato and 3) Fresubin 2kcal as control. Serum and urine samples were collected in kinetics over 24h and processed to be analyzed using LC-QTof analysis. The metabolomics profiles are compared using univariate (ANOVA) and multivariate statistical methods (PCA, PLSDA). The identification of discriminant compounds was performed by tandem mass fragmentation with a high-resolution LTQ-Orbitrab Mass spectrometer and by an extensive inquiry of different online databases.
The HEP2 study is designed to better understand the challenges of living with focal seizures that do not respond to medication, by following 205 people with medication-resistant focal epilepsy over two years to measure changes in health status, healthcare costs, quality of life, and biomarkers of epilepsy severity and treatment response.
High mortality associated with sepsis and Multiple Organ Dysfunction Syndrome (MODS) calls for alternative, individualized therapies in selected patients that might benefit form specific interventions. Role of macrolides as potential immunomodulatory treatment in sepsis is promising, but unclear. Subgroup analysis of previous large-scale clinical trials on patients with ventilator-associated pneumonia or gram-negative sepsis, showed that addition of clarithromycin to standard antibiotic therapy conferred a significant survival benefit in the subgroup of patients with respiratory dysfunction and MODS. The INCLASS study is aiming to assess the efficacy of intravenous treatment of clarithromycin in the reduction of 28-day mortality among patients suffering from these entities.
To identify the potential serum biomarkers with regard to the severity of pneumonia, and to further evaluate the prognostic value of these markers.
