Active clinical trials for "Atrophy"

The aim of this the study is to the assess whether the graft and patient survival, rejection rates and renal graft function after the first year will not differ between both study arms. The investigators will also the evaluate the reduction in the incidence of cytomegalovirus the and improvement of renal function of the everolimus after 1 year.

Chronic atrophic gastritis (CAG) is acknowledged as the precancerous stage of gastric cancer (GC). The present study aims to explore Traditional Chinese Medicine (TCM) syndrome features in different stages of CAG malignant transformation respectively. The proposed study is a cross-sectional study based participant survey conducted in 4 hospitals in Beijing, China. After obtaining informed consent, a total of 2000 study patients will be recruited on-site in hospitals.

Spinal muscular atrophy (SMA) prenatal carrier screening is recommended by American College of Medical Genetics (ACMG) and American College of Obstetrics and Gynecology (ACOG). However, in Thailand, there are no standard protocol for SMA prenatal carrier screening.

In this, here we want to present a new method for analysis variation in gene copy number for patients and carriers of SMA. This is a relative quantitation method and, therefore, relies on the inclusion of one or more internal control or reference sequences; quantitation of DNA is relative to this reference sequence of known copy number. A peak height from within a potentially duplicated or deleted target region is amplified simultaneously with a disomic reference region in a multiplex PCR system.

Background: Atrophic gastritis (AG) is the single most important precursor condition for gastric cancer (GC) known so far. H. pylori infection is the most important causative agent of gastritis, and subsequent AG. The GastroPanel test (Biohit HealthCare, Helsinki, Finland), a blood test evaluating the four biomarkers specific for the gastric mucosa pepsinogen I (P-PGI), pepsinogen II (P-PGII), gastrin-17 (P-G-17) and H. pylori antibody (P-HpAb), is the first non-invasive diagnostic tool providing possibilities for detecting the patients at risk for GC and peptic ulcer as well as malabsorption of vitamin B12, iron, magnesium, calcium and some drugs. A well designed clinical study is warranted to fully assess the performance of GastroPanel examination in detecting the gastric lesions which can lead to GC. The investigators aim to perform a clinical study in an adult population in United Kingdom in order to determine the diagnostic accuracy of the GastroPanel test in evaluating AG and other specific gastric conditions associated with an increased risk for GC. Methods: Two hundred and fifty patients (45 years and older, both genders) will be enrolled among the patients with dyspepsia referred for gastroscopy at Homerton University Hospital (London, United Kingdom). During the same visit, all patients are subjected to gastroscopy examination, with directed biopsies from the antrum and corpus, following the protocol of the operative link on gastritis assessment (OLGA) classification for chronic gastritis and Sydney Classification. Biopsies are examined at the Pathology laboratory of Homerton University Hospital and interpreted using the OLGA staging system as well as the Sydney system for classification of gastritis. Specific aims: The principal goal of this clinical trial is to establish the performance of the GastroPanel examination in detecting AG and other specific gastric conditions associated with an increased risk for GC. In particular, the investigators will evaluate AG in the antrum, AG in the corpus, AG in both antrum and corpus (=atrophic pangastritis), biopsy-confirmed dysplasia (intestinal metaplasia) of the gastric mucosa. For all these conditions, the investigators will calculate the diagnostic accuracy of the GastroPanel test.

The Motor Function Measure (MFM), a reliable tool assessing motor function and its progression in most neuromuscular diseases, is widely used in France in many teams. It can be used regardless of the severity of the motor impairment or the ambulatory status of the patient, allowing its use throughout the whole follow-up period of the patient, even in case of the loss of walking. Two versions of the MFM exist, one composed of 32 items validated for patients from 6 years old (MFM-32) and a shorter version composed of 20 items validated for patients between 2 and 6 years old (MFM-20). In order to show the possible use of MFM-20 as early as the age of 2 years to validly and reliably monitor the evolution of the motor function of children treated with Nusinersen, we propose in this project to study the sensitivity to treatment-induced change of MFM-20 and the validity of the scale in this population.

Spinal Muscular Atrophy (SMA) is neurodegenerative disease of anterior horn cells of spinal cord and represents the second more frequent pathology in childhood. According to the age of onset and the maximum motor function the disorder is classified in 4 types. Patients with SMA II and SMA III often use orthoses to achieve postural and dynamic functions. In this retrospective observational study the investigators describe the characteristics of sitting position, standing and walking correlated to type and time of orthoses used.

The purpose of this study is to compare the abilities of high-speed,high-resolution (HR) optical coherence tomography (OCT) and Stratus OCT for detection of retinal nerve fiber layer (RNFL) loss in eyes with band atrophy (BA) of the optic nerve.

The purpose of the study is search the interrater and intrarater reliability of the quadriceps muscle using rehabilitative ultrasound imaging and search for an association between sarcopenia and quadriceps muscle in poststroke patients.

The primary objective of this study is to investigate the natural history of spinal muscular atrophy (SMA) types 2 and 3 patients in Taiwan. This study will provide further insights into the clinical course SMA. Several analyses will be conducted regarding overall survival, demographic characteristics, motor function, respiratory and nutritional support, and genotype and phenotype correlation.
