There are about 2333 clinical studies being (or have been) conducted in Ireland. 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.
This research will be a randomised controlled trial (RCT) investigating whether the use of Horizontal Platelet Rich Fibrin (H-PRF) increases implant stability compared to those implants placed without H-PRF, and therefore, contributes to the implant's overall success. H-PRF is a second generation platelet concentrate that consists of a fibrin mesh containing cytokines and leukocytes. It has been shown to stimulate mesenchymal stem cells and osteoblasts that encourage bone formation as a result of the growth factors released from platelets, which should aid in osseointegration of implants. There is limited research that investigates the effects of H-PRF on implant stability. There is, however, some evidence that platelet-rich fibrin (PRF), which is produced in a fixed-angle centrifuge, increases implant stability and H-PRF is considered the evolution of PRF products. This research would follow a H-PRF preparation protocol which involves taking a sample of venous blood from patients using a butterfly needle to collect up to 8-9ml tubes of blood. After the tube of blood is collected, it would immediately be placed in a horizontal centrifuge machine with 3 tubes of water to balance the centrifuge, and placed opposite each other. A set rpm and time will be chosen, and the centrifuge will run until the time is complete. The H-PRF clots would then be ready and taken out of the tubes to separate them from the red blood cells. Following randomisation, implants will be placed in the upper or lower jaws of patients attending the Dublin Dental University Hospital using the standard implant protocol. Half of the implants will be coated with H-PRF, the other half (control group) would be placed without HPRF. Implant stability and marginal bone levels will be measured at three different stages: 1) Initial implant placement, 2) Second stage surgery when the implant is uncovered after healing and integrated with the bone, 3) When the definitive crown or bridge is attached to the implant. Insertion torque at baseline will also be measured. The above results will be collected and assessed to determine the effects of H-PRF, if any, on implant stability and the preservation of bone levels around implants.
This study will systematically investigate the effects of a diet with decreased energy density, reduced glycaemic index, and significantly increased dietary fibre, on post-prandial glycaemic response, satiety, gastrointestinal tolerability and gut microbiota composition and function in individuals with excess body weight (Body Mass Index (BMI) 25-35kg/m2). Hypothesis: The investigators hypothesise that a diet enriched in fibre will be beneficial to post-prandial glycaemic response, well tolerated and satiating, as compared to the standard Western-style diet.
The investigators aim to determine the effect of virtual appointments on compliance with Twin Block wear. Patients satisfying the inclusion criteria requiring a Twin Block appliance will be requested to participate in the study. Those selected will be allocated to either the intervention or control group. The control group will receive routine verbal instruction and a standard information leaflet at the start of their treatment. The intervention group will additionally receive virtual appointments over the initial period of treatment involving focussed discussion on twin block wear experience and use of visual aids. Wear time will be objectively recorded in both groups using a temperature-sensitive microsensor embedded in the Twin Block appliance, and occlusal changes will be measured at each standard recall visit. A comparison of the data obtained from each group will be undertaken to determine whether there is a significant difference in compliance with twin block wear between participants who receive adjunctive virtual appointments to those who do not.
The All-Ireland Infectious Diseases (AIID) Cohort is a multicentre, prospective, longitudinal observational cohort that enrols consecutive adult subjects attending participating institutions for infectious disease services. This is an ongoing prospective observational cohort of unlimited duration.
Traumatic hand injuries account for up to one third of acute hospital presentations. Current guidelines and standards of care recommend patients with hand trauma are seen by hand therapists, typically occupational therapists. The proposed study aims to explore the effectiveness of occupational therapy-led hand therapy services for the adult population presenting acutely to an injury unit or emergency department setting with a hand condition. The research project will consist of an analytical study, involving four different sites in Ireland to enrich findings, and to aid future service development. One site will be the comparison site, as it does not have access to occupational therapy, and will offer patients 'care as usual' upon attendance. Outcome measures will be used for all participants and will be completed at initial patient contact, at week eight and at six months. It is hoped the current proposed study will help shape future service development for those with hand injury including provision of evidence based occupational therapy assessment and intervention.
This study aims to investigate the effects of a 12-week aerobic (cardio) exercise intervention in people with Major Depressive Disorder. Measurements taken before, during, and following the 12-week intervention will include assessments of cognition, cardiorespiratory fitness, stress, mood and emotion, and gut bacteria.
This protocol outlines a planned mixed methods feasibility trial which will be conducted to examine the feasibility and acceptability of a physiotherapy-led exercise-based telerehabilitation programme for groups of people with mixed chronic health conditions.
This is a real world data collection observational study at a single site. There are both prospective and retrospective cohorts. The study will examine the safety and effectiveness of the Synergy cervical disc system in patients with degenerative cervical disc disease.
Rett syndrome (RTT) is an X-linked genetic disorder that causes severe neurological development disorder. In its classic form, it seems to affect almost exclusively females with an incidence of up to one in 10,000 females. Patients affected by Rett Syndrome can present a wide range of symptoms, in different combinations and of varying intensity, such as slowed growth of head circumference, abnormalities in walking and balance, loss of functional use of the hands often replaced by repetitive and stereotyped hand movements like "hand washing", loss of communicative-relational skills including expressive language, epilepsy, breathing abnormalities, and osteo-muscular alterations. In light of the growing potential of clinical therapies, identification and early diagnosis are considered essential. Many disease modification strategies have been achieved through translational research studies and clinical trials that have allowed the recognition of the most effective therapeutic and clinical interventions to date. This study arises from the need to advance in the understanding of the pathogenesis of RTT through a multicentric collaboration in order to (a) identify early biomarkers of RTT (b) delve into the alterations of interconnectivity, crucial for understanding the loss of motor functions and language through systematic collection of anamnestic, genetic, and clinical-instrumental data. The aim is to provide a valuable contribution to the study of the clinical phenotype of Rett and the identification of early interventions.
Circadian rest-activity rhythm disorders are common in patients with cancer, particularly in advanced disease. A recent international e-Delphi study has outlined recommendations for the assessment and reporting of the disorder and subsequently an observation study is underway assessing a cohort of patients with advanced cancer. Affected patients are eligible to enter a feasibility study assessing a non-pharmacological multi-modal intervention.
