Active clinical trials for "Disease Progression"

Objective: To investigate the efficacy and safety of radiotherapy combined with EGFR-KI in the treatment of stage III EGFR mutant lung cancer. Methods: Stage III EGFR mutant lung cancer cases who underwent radiotherapy combined with EGFR-TKI from December 2014 to December 2022 at the People's Hospital of Laibin, the First People's Hospital of Yulin, the Affiliated Hospital of Guilin Medical College, and the Park East Hospital of Guangxi Medical University Kaiyuan were collected, and the primary index of the study was progression-free survival (PFS), and the secondary indexes were objective remission rate, overall survival, recurrence pattern, and adverse events. Survival analysis was performed using the Kaplan-Meier method with Log rank test for univariate analysis and Cox proportional risk model for multifactorial analysis of prognosis.

The high prevalence of myopia - especially in Asian countries - is well documented, as are the sight-threatening complications of high or degenerative myopia. Retinal detachment, glaucoma, vitreal degeneration and focal retinal changes occur secondary to the progressive axial elongation of the eye with age. Specialty rigid lenses have long been shown to lessen this progression in the pediatric population; orthokeratology (ortho-k) lenses are worn at night and change the corneal topography to correct low to moderate amounts of myopia. This same axial elongation has also been shown to occur in young adults with high near demands, however to our knowledge, there are no studies examining the effect of ortho-k lenses in this population. Our project seeks to investigate the efficacy of ortho-k in slowing axial elongation and myopic progression in subjects between the ages of 21-30. Results will help elucidate what role these specialty lenses may have in the management of the myopic patient throughout their development, as well as what potential they have in prevention of associated degenerative changes.

Background: Physiotherapists (PTs) in primary health care manage patients with a large variation in medical diagnosis, age, functional status, disability and prognosis. Lack of knowledge and systematically collected data about patients treated by PTs in primary health care has prompted this longitudinal observational physiotherapy project in Norway. This paper aims to describe a method for developing a database of patients managed by PTs in primary health care to study patients' characteristics, treatment courses and prognostic factors. The study is a longitudinal observational project, following patients through physiotherapy treatment periods in primary health care in Norway and until one year after inclusion. The project involves both private practice and municipally employed PTs working in primary health care in eight municipalities in Norway. The participants are recruited to three different parts of the project depending on age and whether they are referred to a private practice or a municipally employed PT. All data are recorded electronically, transferred and stored securely. All patients complete extensive questionnaires providing information about demographics, disability and function, pain related variables, treatment and evaluation of treatment as well as clinical tests. The PTs have access to their own patients' data. The investigators have also prepared for linkage to national patient registers and population-based studies to be able to gather further important data. This project will have important implications for physiotherapy services in primary health care. The database already contains almost 3000 patients, and data collection is ongoing. Preliminary analyses suggest that the patients included so far are representative of the larger population of patients treated by private practice or municipally employed PTs in Norway. This large scale prospective physiotherapy project will provide knowledge about the patient groups treated, treatment given as well as short and long term outcome of the patients.

Background: COVID-19 virus infection differs among people. Some people have no or mild symptoms. For others, COVID-19 is life threatening and causes damage to the body s organs. Researchers want to better understand the virus to learn how to kill it. Objective: To understand how the COVID-19 virus causes wide differences in how sick one can become from the infection. Eligibility: People ages 18-80 with COVID-19 infection Design: Participants will be screened with a review of their medical records. Participants who enter the study at the beginning of their COVID-19 infection will stay in the hospital until they are healthy enough to go home. Those who enter after they have recovered may need to stay in the hospital 1-2 nights to perform the study tests. Participants will have MRI and CT scans of the brain, heart, and lungs. They will lie in a machine that takes pictures of the body. For the MRI, soft padding or a coil will be placed around their head and chest. They may receive a dye injected into a vein. Participants will have an ultrasound of the kidneys and heart. Participants will provide blood and urine samples. They will provide nasal swabs. Participants will have a bronchoscopy. A thin tube will be placed through the nose or mouth into the airway. Saltwater will be squirted into the lungs and removed by suction. Participants may provide a spinal fluid sample. A needle injected into the spinal canal will obtain fluid. Participants will have lung and heart function tests. At various points after recovery, participants will repeat many of these tests.

The primary objective of this study is to quantify disease progression measured by best corrected visual acuity (BCVA) in the real-world setting among Choroideremia (CHM) participants. The secondary objectives are to describe demographic and baseline clinical characteristics among CHM participants and to match CHM participants in the Intelligent Research in Sight (IRIS®) Registry to Biogen's investigator sponsored trial (IST) study population using propensity score matching.

A retrospective observational study that will enable us to collect retrospective data from the clinical records of LGMD 2E patients in order to highlight any possible correlation between: clinical variables and patient age, clinical variables and other clinical variables, clinical variables and clinical outcomes. The study will help to define the natural history of this rare disease and to ameliorate the management of these patients.

Some researches have shown surgery may acquire progression-free (PFS) benefit for selected patients with metastatic gastrointestinal stromal tumor (GIST) who received first-line imatinib and second-line sunitinib. However, impact of salvage surgery on pre-treated GIST patients receiving third-line regorafenib facing progression is not yet reported. Investigators retrospectively reviewed patients with regorafenib treatment with salvage surgery.

There is limited empirical data documenting disease progression and impact on quality of life for patients with X-linked hypophosphatemia (XLH). This study seeks to investigate the impact of XLH in adults living in the UK retrospectively and prospectively over a 12 month period, using qualitative interviews, SEIQoL-DW, EQ-5D-5L, SF36 quality of life tools. XLH is a rare, genetic, chronically debilitating and deforming condition (www.nice.org.uk/guidance/HST8). XLH is characterised by renal phosphate wasting, hypophosphatemia and defective bone mineralisation. The incidence of XLH is reported to be between 1:20,000 and 1:25,000 live births. In the UK, it is estimated that there are around 250 paediatric XLH patients and around 2,500 adult XLH patients (Delmestri,et al [Unpublished report]2018). The clinical phenotype of XLH is varied amongst patients, even among affected members of the same family. This can range from no signs or symptoms, slow growth in children, short stature, bone abnormalities that can affect movement and result in pain, bowed legs and knocked knees (where lower legs are positioned at an outward angle), tooth abscesses and excessive dental caries and hearing loss (adult patients only). This study will recruit 36 adults living with XLH, who are aged 28 years or over and living in the UK. The study will be advertised by the Sponsor and funder Medialis Ltd and via the patient organisation Metabolic Support UK. All study activities will take place via tele-visits and online questionnaires. The study will last approximately 2 years, allowing for one-year recruitment and a further 12 months to conduct all study visits.

Respiratory infections such as colds, flu and pneumonia affect millions of people around the world every year. Most cases are mild, but some people become very unwell. Influenza ('flu') is one of the most common causes of lung infection. Seasonal flu affects between 10% and 46% of the population each year and causes around 12 deaths in every 100,000 people infected. In addition, both influenza and coronaviruses have caused pandemics in recent years, leading to severe disease in many people. Although flu vaccines are available, these need to change every year to overcome rapid changes in the virus and are not completely protective. This study aims to find and develop predictive tests to better understand how and when flu-like illness progresses to more severe disease. This may help to decide which people need to be admitted to hospital, and how their treatment needs to be increased or decreased during infection. The aim is to recruit 100 patients admitted to hospital due to a respiratory infection. It is voluntary to take part and participants can choose to withdraw at any time. The study will involve some blood and nose samples. This will be done on Day 0, Day 2 and Discharge from hospital, and an out-patient follow-up visit on Day 28. The data will be used to develop novel diagnostic tools to assist in rational treatment decisions that will benefit both individual patients and resource allocation. It will also establish research preparedness for upcoming pandemics.

Prospective observational study with 7-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and 1, 3 5, and the 7-year recall digital 3D scans will be made, which will be compared and subtracted.
