Filter by:The study is a prospective, double blinded, placebo controlled, randomized study to evaluate the effects of daily oral estrogen supplements on bone health, sexual and reproductive health, quality of life and markers of inflammation and lung function when given to hypogonadal women with Cystic Fibrosis related Bone Disease (CFBD).
This study evaluates the feasibility of using differentially methylated insulin DNA, a biomarker of beta cell death, in determining the time course of beta cell death and development of diabetes in people with cystic fibrosis. Study participants with cystic fibrosis and healthy control participants will have a blood sample drawn in order to measure the levels of differentially methylated insulin DNA.
The investigators aim to test the feasibility and effectiveness of a pre-meal snack to reduce the postprandial glycemia (PPG) excursion after a breakfast consumption in adult patients with cystic fibrosis (CF). The investigators also want to investigate the impact of a postprandial exercise to reduce the PPG excursion. An improvement in PPG excursions can improve the condition of CF patients primarily by delaying the onset of cystic fibrosis related diabetes (CFRD) and / or by reducing the risk of lung function loss.
Cystic fibrosis is an inherited disorder that causes severe damage to the lungs, digestive system, and other organs in the body. Individuals with cystic fibrosis often have poor weight gain and growth that can negatively impact health further by worsening lung function. Additionally, persons with the disease typically need more than the usual calories on a daily basis. Most institutions estimate these patients' caloric needs using weight, age, and sex based mathematical formulae. However, numerous studies show that use of these formulae often yields inaccurate caloric values. Use of indirect calorimetry may give more accurate estimates of caloric needs in patients with cystic fibrosis. The aim of our study is to assess the accuracy of caloric estimates generated using one such widely used mathematical formula, the Harris-Benedict equation, and to compare this calorie value with that obtained from indirect calorimetry testing in pediatric and adult patients with cystic fibrosis. Study investigators will use the newly calculated caloric requirements in dietary counseling. Changes in weight and lung function after 3 months will be compared to participants' historical changes.
Randomized, double blind, placebo controlled study. The study has two parts: Dose-finding part, followed by longer term follow-up (6 months)
This study will evaluate the pharmacokinetics (PK), safety, tolerability, efficacy, and pharmacodynamic effect of VX-445, tezacaftor (TEZ), and ivacaftor (IVA) when dosed in triple combination (TC) in Cystic Fibrosis (CF) subjects 6 through 11 years of age with F/F and F/MF genotypes.
The aim of this pilot study is to demonstrate the feasibility of viral biomolecular diagnosis in sputum compared to nasopharyngeal swab in cystic fibrosis acute respiratory infection.
According to the U.S. CF Foundation Patient Registry, more than 25% of children and 40% of adults were treated with intravenous (IV) antibiotics for flares of lung disease in 2016. Medication for these flares is often delivered through a peripherally inserted central catheter (PICC). Case series have identified important complications of PICCs in CF patients such as blood clots and infection. The frequency of PICC-associated blood clots in CF patients ranges from 2 to 8%. Catheter-related complications may interfere with completion of therapy and lead to repeated procedures and other complex medical treatments. In some cases PICC complications may discourage patients from accepting future courses of IV antibiotics. Therefore, it is very important to identify patient- and device-related factors that are linked with more frequent complications and to figure out ways to reduce these risks. Proposed risk factors fall into several broad categories. First are catheter-related factors; second are patient factors; and third are catheter-management factors. To date, no multicenter trial has carefully studied PICC complications in a large group of adult and pediatric CF patients from the time each catheter is placed to when it is removed. The main purpose of this study is to see whether the investigators can identify important factors in each of the three categories (patient, catheter, and catheter management) that are linked to various complications.
Physical activity is widely documented as one of the cornerstones of Cystic Fibrosis (CF) management as it is directly linked to mortality and quality of life. Levels of physical inactivity and sedentary behaviour have been poorly investigated among the CF population in Ireland. The measurement of these behaviours is important in order to monitor prevalence amongst people with CF (PWCF) and determine methods by which health care providers can assist with maintaining and enhancing physical activity. The use of physical activity monitoring can provide health care providers with insightful real world analysis of physical activity and exercise behaviours. Over the last decade there has been many advancements in technology and fitness tracking with positive results being demonstrated in the healthy population and in chronic diseases such as Diabetes Mellitus II, post surgery and Multiple Sclerosis. Limited research has been conducted among PWCF to date. The aim of this research project is to examine physical activity levels amongst PWCF and determine the effect of a 12 week randomised parallel intervention on a number of health outcomes. Participants will be provided with an accelerometer to assess physical activity and sedentary behaviour at baseline. The participants will then undergo further baseline testing to determine exercise capacity, body composition, quality of life, breathlessness, sleep quality and wellbeing. Baseline short and long term goals will be established together with the participant and physiotherapist. Participants will then be randomly allocated to either the intervention or the comparator. A researcher independent of the recruitment process (MC) will complete the first random allocation using a sealed opaque envelope. Following this a minimisation randomisation procedure will be completed based on lung function, where FEV1 of <70% predicted lung function will be classified as having mild lung disease. While those with an FEV1 of 30-50% predicted lung function will be classified as having moderate lung disease, with <30% indicating severe lung disease. Allocation will be revealed after recruitment and baseline assessments have occurred. Both groups will receive a fitness tracker which will be linked to an online monitoring system (Fitabase) for 24 weeks. The intervention group will receive personalised feedback via a text message every week on their physical activity levels as measured by their fitness tracker and progress on attainment of their goals established at the start of the study. Feedback will be provided from their CF physiotherapists. The comparator group will not receive any feedback on their Fitbit data. After 12 weeks both groups will be re-assessed. Thereafter, both groups will continue with the Fitbits alone for 12 weeks. Finally outcome measures including lung function, physical activity levels, aerobic capacity, quality of life, sleep quality, muscle mass and well-being will be re-assessed again at 24 weeks. Following the intervention semi structured interviews will be conducted to qualitatively establish satisfaction with the interventions and provide insight into barriers and enablers to achieving goals and physical activity levels.The results of this study may provide valuable insights into potential interventions to optimise the health and well-being of PWCF.
The presence of a nonsense mutation leads to the rapid degradation of the carrier mRNA mutation by a mechanism called NMD (nonsense-mediated mRNA decay) [6, 13]. There are currently 3 main strategies at least for correcting nonsense mutations: exon skipping, inhibition of NMD and nonsense mutation readthrough. In the laboratory, we developed a strategy for correcting nonsense mutations combining inhibition of NMD and activation of translecture. For this purpose, we have constructed screening systems to identify NMD-inhibiting and/or readthrough enhancers. The molecules thus identified are then tested on cell lines and in murine models carrying a nonsense mutation. One of our goals is to select a set of molecules that can correct effectively nonsense mutations. For this we have to test these molecules on a great diversity of nonsense mutations. This work will: - determine if we can correct all the nonsense mutations tested with at least one of our molecules - determine what is common within a group of mutations corrected by a given molecule - be able to assign the parameters that make one mutation is corrected by one molecule and not or little by another. This study will therefore improve our theoretical knowledge on the recognition of premature stop codons but also to propose therapeutic approaches for the correction of nonsense mutations of the CFTR gene in cystic fibrosis in a targeted way for a patient.
