Filter by:Subarachnoid hemorrhage (SAH) is a common and extremely critical disease in neurosurgery. The mortality rate within 30 days of the onset of SAH is as high as 50%, and about 15% of SAH patients die without reaching the hospital. Nearly half of the survivors have severe neurological dysfunction, causing a huge burden to the families and society of the patients. Recently, the introduction of the "glymphatic-meningeal lymphatic vessels" drainage system has updated the current concept of intracranial cerebrospinal fluid circulation. After subarachnoid hemorrhage, a large number of blood components flooded into the subarachnoid space and entered the cerebrospinal fluid circulation, which directly affected the function of the lymphatic-meningeal lymphatic drainage system. Many preclinical animal studies have pointed out that the damage of the lymphatic-meningeal lymphatic drainage system is involved in the aggravation of cerebral edema, neuroinflammation and hydrocephalus after SAH, which ultimately leads to poor prognosis of patients. However, at present, the changes of the glymphatic-meningeal lymphatic drainage system after SAH have only been confirmed in animal models, and clinical evidence is lacking. With the development of imaging technology, many research teams have confirmed the functional changes of the lymphatic-meningeal lymphatic drainage system in Alzheimer's disease and Parkinson's disease by using different sequences of non-invasive MRI, such as 3D T2-FLAIR, DTI-ALPS and other sequences.
To get a better insight into the central conducting lymphatic system in adult volunteers with Noonan Syndrome (NS) without clinical symptoms or signs of lymphatic disease compared to NS and CardioFacioCutaan syndrome patients with severe lymphatic disease
Supermicrosurgical LVA has been proven effective in treating moderate to severe lymphedema, including cases with diffuse dermal backflow (DB) and even severe lymphatic fluid leakage. Therefore, the use of LVA should not be limited to mild lymphedema, and its indications should be expanded to become a primary surgical approach for more severe lymphedema cases. Among all surgical procedures for lymphedema, LVA is the least invasive, allowing for rapid recovery, minimizing the complications, and reducing medical costs.
Background: The lymphatic system is a network of vessels that carry a clear fluid called lymph through the body. Problems in the lymphatic system can cause pain, fluid buildup, and issues with immunity. There is much researchers do not understand about lymphatic anomalies. In this natural history study, they will collect data from a lot of people over a long time. Objective: To better understand why lymphatic anomalies develop. The goal is to improve future treatments. Eligibility: People aged 0 days and older with a suspected or confirmed lymphatic anomaly. Their unaffected parents or siblings aged 7 years or older are also needed. Design: Participants may remain in the study indefinitely. Affected participants may be evaluated every 10 months to 2 years. Some participants will be seen over telemedicine. Others will be seen at the NIH Clinical Center for 2-5 days. All participants will have a physical exam. They may provide specimens including blood, saliva, hair follicles, stool, skin, and other tissues. Samples may be used for genetic testing. Participants may undergo other tests depending on their medical conditions. The NIH Clinical Center visit may include: Heart tests include placing stickers on the chest to measure electrical activity and using sound waves to capture pictures of the heart. A lung test measures the muscle strength in the chest. Participants will blow into a tube. Photographs may be taken of participants faces and other features. Imaging scans will take pictures of the inside of the body. One scan will measure bone density. One type of scan tracks how lymph fluid moves through the body. Participants will be under anesthesia, and they will be injected with a dye.
This study aims to investigate whether octreotide, a medication used off-label to treat chylothorax, has a direct effect on human lymphatic drainage. To study the effects of octreotide, the researchers conducted a pre-clinical experiment using human lymphatic vessels mounted in a myograph chamber and a clinical experiment in which a double-blinded, randomized, cross-over trial was conducted in 16 healthy adults. The results of the study will be used to determine the role of octreotide in the treatment of chylothorax and other lymphatic disorders.
The primary aim of this study is to investigate and test whether the use of combined indocyanine green (ICG) lymphography and ultra high frequency ultrasonography can correctly identify lymphatic vessels and venoles in close proximity to each other, for identification prior to lymphovenous anastomosis (LVA) surgery.
This is a Phase 3 study to investigate the safety and efficacy of the investigational drug, zilovertamab, when given in combination with ibrutinib in patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL).
This is a multi-center Phase 2 study to determine the safety and efficacy of sepantronium bromide (SepB) in adult patients with relapsed or refractory high-grade B-cell lymphoma
Primary Objectives: Long-term safety of BIVV003 in participants with severe sickle cell disease (SCD) and ST- 400 in participants with transfusion-dependent beta-thalassemia (TDT) Secondary Objectives: - Long-term efficacy of the biological treatment effect of BIVV003 in SCD - Long-term efficacy of the clinical treatment effect of BIVV003 on SCD-related clinical events - Long-term efficacy of the biological treatment effect of ST-400 in TDT - Long-term efficacy of the clinical treatment effect of ST-400 in TDT
In venous ulcer, venous insufficiency is accompanied by lymphatic insufficiency. Manual lymphatic drainage (mld) technique cause to increase contraction rate of lymphatic collector and venous flow. It is known that Manual lymphatic drainage accelerates microcirculation, enabling nutrients and oxygen to reach tissues and at the same time removing residual substances from the tissue. We hypothesis that if we inrease to lypmhatic activity with MLD, we could stimulate healing of ulcer. The aim of this study to investigate the effect of manual lymphatic drainage on venous ulcer healing.
