Active clinical trials for "Atrophy"

Multiple system atrophy (MSA) is a rare neurodegenerative disorder that leads to major disability, forcing patients and caregivers to adapt their environment and lifestyle. Once they receive the diagnosis, patients and caregivers need to understand the symptoms, cope with them, to digest the diagnosis... All these needs are not completely addressed by the current model of care so we created a therapeutic educational program (TEP) program that will last 12 months, involving both patients and caregivers, including a mixed model of in-person visits and continuous on-line activities. Our project aims to target early MSA patients and their caregivers, proposing to test the feasibility (primary objective) of an innovative therapeutic educational program (TEP) for MSA patients.

SMA (Spinal Muscular Atrophy) is a rare neuromuscular disease characterized by motoneuron damage. Symptoms consist of respiratory involvement with numerous respiratory infections and eventually respiratory failure, for which NIV (Non Invasive Ventilation) is often used. Ventilation machines are in close contact with the respiratory tract of patients. They contain heated water to humidify the circuit. These humid and warm environments are conducive to the development of bacteria such as Pseudomonas aeruginosa. In this context, it is interesting to look for the presence or absence of bacteria, in comparison with the respiratory ecology of the patients. The aim is to highlight the microbiological role of NIV on the occurrence of respiratory bacterial infections or secondary infections in patients with SMA. To do this, samples are taken from the machines, and ECBCs are performed on patients during respiratory physiotherapy sessions.

This was an interventional prospective randomized clinical trial (RCT) in parallel groups. The sample size is 32 patients who were randomly divided into two groups depending on the surgical intervention used. First group - patients underwent increasing the thickness of the mucous membrane using free connective tissue graft from tuberosity area of the upper jaw. Second group - patients used collagen matrix Fibro-Gide" (Geistlich Pharma AG, Bahnhofstrasse 40, 6110 Wolhusen, Switzerland; registration in Russia 19.08.2020 No FSZ -20207/11765). In the postoperative period the value of soft tissue thickness gain, severity of pain, collateral edema, amount of analgesics consumed, soft tissue aesthetics, keratinized mucosa width, quality of life and duration of surgery were assessed.

The sample size is 35 patients who were randomly divided into two groups depending on the surgical intervention used. First group - patients underwent increasing the thickness of the mucous membrane using free connective tissue graft from tuberosity area of the upper jaw. Second group - patients used collagen matrix "Fibromatrix" (LLC "Cardioplant", Russia; registration in Russia 20/05/2019 No FSZ 2019/83671). In the postoperative period the value of soft tissue thickness gain, duration of surgery, severity of pain syndrome and quality of life were assessed. Also, after 3 months simultaneously with installation of gingiva formers biopsy specimens were sampled with mucotome in the area of the intervention followed by histomorphometric analysis of the obtained biopsies.

Introduction: Gastric atrophy and intestinal metaplasia are the principal precursors for gastric cancer and, therefore, are considered gastric premalignant conditions. Although current guidelines recommend surveillance of individuals with these conditions, the best method for its identification and staging (histological vs endoscopy) and the best time schedule for follow-up are still controversial. Aims: To describe for the first-time patients with premalignant conditions both clinically (familial history), histologically (OLGA/OLGIM; complete/incomplete metaplasia) and endoscopically (EGGIM) using validated scales and to describe evolution of these parameters through time. To estimate prospectively the gastric cancer risk according to EGGIM stages. To define the best endoscopic surveillance follow-up for the several stages considering clinical, histological and endoscopic factors. Methods: Multicenter study involving different gastroenterology departments from several countries. Consecutive patients older than 45 years scheduled for upper endoscopy in each of these centers will be evaluated by High-Resolution- endoscopy with virtual chromoendoscopy and EGGIM will be calculated. Guided biopsies (if areas suspicious of IM) and/or random biopsies (if no areas suspicious of IM) in antrum and corpus will be made and OLGA/OLGIM stages calculated. Patients will be evaluated in clinical consultation and database will be fulfilled. All patients will be eradicated for Helicobacter pylori infection if positive. At that occasion, all the patients with EGGIM>5 and/or OLGA III/IV and/or OLGIM III/IV will be randomized for yearly (12 to 16 months) or every three years (32-40 months) endoscopic follow-up during a period of 6 years (SUPREME I). Endoscopic observational follow-up will be scheduled for patients with EGGIM 1-4 and OLGIM I/II at 3 and 6 years (SUPREME II). For individuals with no evidence of IM (EGGIM 0 and OLGIM 0, OLGA 0-II) a follow-up endoscopy 6 years after will be proposed (SUPREME III).

Parkinson's disease (PD) is the second most common neurodegenerative disease. Multiple system atrophy (MSA) is a relentlessly progressing rare neurodegenerative disease of unknown etiology. The differential diagnosis between the MSA-Parkinsonism (MSA-P) subtype and PD can be very challenging in early disease stages, while early diagnostic certitude is important for the patient because of the diverging prognosis. At the time being, there exists no validated objective biomarker to guide the clinician. Dysarthria is a common early symptom in both diseases and of different origin. The ambition and the originality of this project are to develop a digital voice-based tool for objective discrimination between PD and MSA-P.

The goal of this pilot interventional study is to learn about the use of an in-home harness system in children who have been treated for spinal muscular atrophy. The main questions it aims to answer are: Is the in-home body weight support harness system a feasible option for families to use? Is the in-home body weight support harness system a useful tool for children treated for spinal muscular atrophy? Is the in-home body weight support harness system a safe tool for children treated for spinal muscular atrophy? Participants will be given an in-home body weight support harness system and taught how to use it. Families will document how often and for how long they use the system over 6 months. Children will be given tests of motor function at the beginning, 3-months, and 6-months. At the end of the study, families will be asked to fill out a questionnaire about thier experience using the system.

Spinal muscular atrophy (SMA) is a rare, treatable, genetic disease that typically occurs in infancy and early childhood. SMA progressively, and irreversibly, destroys motor neurons in the brainstem and spinal cord, which control movement, in turn leading to deterioration or loss of muscle strength. This can begin during the first 3 months of a child's life, and in those with the most common and severe type of SMA, 95% of all motor neurons can be lost before the age of 6 months. The majority of children with this type of SMA, if untreated, will not survive beyond 2 years of age without permanent ventilatory support. Of those who do, many will not achieve independent sitting and few walk independently. A challenging aspect of treating SMA is the delay in its diagnosis, usually after disease onset. Diagnosis usually occurs when the affected child presents clinical symptoms, by which point a significant portion of their motor neurons will have been irreversibly lost. In contrast, infants and children with SMA who are identified and treated at an early stage, especially those treated pre-symptomatically, show much better motor development. Given that SMA is caused by deletions or mutations in the survival motor neuron 1 gene (SMN1), it can be detected via genetic testing before a child presents with clinical symptoms. This lends itself to newborn genetic screening, through which pre-symptomatic diagnosis of SMA can be made as early as possible, providing the opportunity for substantially enhanced therapeutic effects and outcomes. The aim and objective of this screening study is to assess the uptake, reliability, and feasibility of neonatal screening for SMA in a UK setting. It is hoped that by doing so it will help establish the early detection, diagnosis, and access to the recently available therapeutic options for SMA.Screening will be done through the routine UK newborn blood spot screening pathway, using spare capacity from a newborns' Guthrie card (dried blood spot sample). A major objective of the design of this protocol and the processes it describes, together with the staff funding secured, has been to ensure that it will not interfere with the standard screening procedure in any way.Recruitment will be carried out in the maternity units of four hospital trusts in the Thames Valley: Oxford University Hospitals NHS Trust, Royal Berkshire NHS Foundation Trust, Milton Keynes University Hospital NHS Foundation Trust, and Buckinghamshire Healthcare NHS Trust.
