Filter by:Intracerebral hemorrhage (ICH) is a subtype of stroke associated with high mortality and disability. Basic and clinical research has contributed to our understanding of the complex pathophysiology in ICH. However, questions regarding acute diagnosis, therapeutic decisions, and prognostication of ICH remain unanswered. Molecular biomarkers and imaging markers have revolutionalized diagnosis and treatment of many diseases, such as troponin use in myocardial infarction and magnetic resonance imaging (MRI) scan in ischemic stroke. Therefore, the investigators aim to discovery the potential biomarkers by screening samples of blood, cerebral spinal fluid, urine, saliva, and even tissues (if available) from ICH patients, and imaging markers via serial multimodality imaging scans such as computed tomography(CT), magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), positron emission tomography (PET), etc. These molecular and imaging markers would assist in contributing additional information to current tools for onset warning, diagnosis, therapy monitoring, risk stratification, intervention and prognosis for ICH patients.
This is a retrospective, hospital-based and multi-center study aiming at investigating the potential exposures associated with the formation, progression, and rupture of intracranial aneurysms in Chinese population.
To evaluate the effect of using a mathematical model developed through pre- and post-surgical hemoglobins to predict the volume to aspirate in patients undergoing primary body liposuction.
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.
The goal of this observational study is to learn about quality of life, stress and caregiver burden in patients with stroke and their caregivers. The main question is: • to discover the factors associated with quality of life and stress in patient-caregiver dyads. Participants will be asked to fill out questionnaires and agree to provide a hair sample (in order to measure stress hormones in hair) and consent to use of their routine clinical and laboratory data. Researchers will compare a group of participants without stroke to establish a comparable baseline.
Patients with colorectal cancer (CRC) have a higher risk of both venous thromboembolism (VTE) and major bleeding (MB). Patients with CRC are underrepresented in the major trials examining treatment of cancer-associated VTE with anticoagulant.
The goal of the randomized clinical trial is to examine the effect of early mobilization on primary and secondary outcomes in patients with subarachnoid hemorrhage caused by aneurysm rupture. Researchers will compare early mobiliziation vs. standrad bed rest care.
To observe the effect of minimally invasive intracranial hematoma aspiration and drainage combined with urokinase injection and drug therapy on prognosis of spontaneous cerebral hemorrhage.
This trial is a clinical prospective observational study. Cases meeting the entry criteria undergo near-infrared spectroscopy(NIRS）detection. Data collection mainly includes hematoma thickness on cranial CT, and bilateral NIRS data.This trial tries to explore the reliability and accuracy of NIRS detection of subcranial hematoma.
Although tonsillectomy is one of the most commonly performed surgeries, a review of literature reveals no articles dealing with the study of intraoperative blood loss in tonsillectomy and adenotonsillectomy according to the use of nondepolarizing muscle relaxants. The primary aim of our trial will be to compare blood loss in the operating theatre and postoperatively in two groups of children having adenotonsillectomy. The trial numbers will be randomised in blocks.
