This study summarizes the experience of precision treatment and postoperative management of various types of cataract, and intend to further improve the quality of Clinical Cataract diagnosis and treatment.
The objective of this study is to assess the safety, efficacy, pharmacokinetics, and immunogenicity of MRG002 as single agent in patients with HER2-positive unresectable locally advanced or metastatic urothelium cancer.
The aims of the study are to compare long-term one-year outcome with or without AirvoTM in stabile hypercapnic COPD patients, who are non-compliant to NIV after an acute exacerbation of COPD.
This is a phase 1 clinical trial of autologous CD7-CAR T cells in the treatment of high-risk acute T-cell leukemia / lymphoma. Twenty subjects will be enrolled. Subjects will be pretreated with chemotherapy prior to infusion of CAR T cells: about 3 days before cells transfusion, the patients who planned to reinfuse CAR T cells were treated with fluorodarabine 30 mg/m2( body surface area) and cyclophosphamide 250 mg/m2( body surface area) for 3 days. Then this study will be using a 3+3 dose escalation approach from dose 1 (DL-1): 5×105 (±20%) to dose 2 (dl-2): 1×106 (±20%). Below the lowest dose was reinfused at the PI's discretion.
The primary objective is to establish a prospective database of clinical information, FACE-Q scores, and patient photographs (as appropriate) to enhance the understanding and practice of facial plastic and reconstructive surgery.
Robotic surgery for common surgical procedures is on the rise despite limited evidence to support its clinical benefit. We intend to to map and characterize the prevalence of the patients'expectation that robotic surgery might be superior to open or laparoscopic procedures and to identify the sociodemographic, clinical and organisational factors associated with this expectation.
Background: The immune response is how the body recognizes and defends itself against foreign and harmful substances. Researchers want to compare the immune responses between young and older healthy adults after they receive vaccine doses for COVID-19. This research may help to determine whether age impacts cell response to COVID-19 vaccines. Objective: To study the immune response of people who receive Pizer or Moderna COVID-19 vaccines. Eligibility: People aged 18 and older who have not had COVID-19 and who either plan to receive the first dose of a COVID-19 vaccine within the next month or have received at least the first of 2 doses of the vaccine within the last 6 months. Design: Participants will be screened by telephone. Participants will not get the COVID-19 vaccine in this study. They must get it through a vaccine location. Participants who have not yet been vaccinated will have 7 visits. The first 4 visits will occur in the first month before and after each vaccination. The last 3 visits will occur 6 months, 1 year, and 2 years after completed vaccination. Participants who have received at least 1 of 2 doses of the COVID-19 vaccine within the last 6 months will have 3 visits. The first visit will occur within 6 months of receiving the first vaccine dose. The last 2 visits will occur 1 year and 2 years after the first vaccine dose. At visits, participant will review their medical history. Their height, weight, and/or vital signs will be measured. They will give blood samples after fasting. They may give urine samples. They may have a nasal swab test for COVID-19.
Little is known about optimal level of positive end-expiratory pressure (PEEP) in patiens who recieved invasive mechanical ventilation for acute decompensated heart failure. We therefore sought to compare clinical outcome according to low versus high PEEP.
The purpose of this study is to find out how often the researchers can avoid an ALND in patients with early-stage, node-positive HR+/HER2- breast cancer who are having upfront surgery. The study researchers think that, if AUS before surgery can help identify people who may have up to 3 affected lymph nodes, it will be possible to perform the less radical standard SLNB during surgery.
A cross-sectional study is expected to conducted by inquiring about the history, diagnosis results and medication details of respiratory diseases of the outpatient pediatric patients with respiratory diseases in the pediatric departments at specialist children's hospital at the second class and above, general hospitals and maternal and child healthcare hospitals. About 10,000 electronic questionnaires are expected to be collected in total, with about 100 participating hospitals and 100 electronic questionnaires from each participating hospital.Diagnosis and treatment information of pediatric patients are expected to be collected in the third week in April, July and October 2021 and in January 2022.
