Filter by:This is a phase Ib, open-label, dose-validating and safety study of caffeine in neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia.
Therapeutic hypothermia (TH) is accepted worldwide as a standard of care for infants born at or beyond 36 weeks gestational age with moderate-to-severe hypoxic ischaemic encephalopathy (HIE). While central nervous system is the most affected organ system , multiorgan dysfunction including renal, pulmonary, cardiac, and/or gastrointestinal (GI) compromise is not infrequent. Although the process of 'cooling' itself is well defined, based on high-quality randomized controlled trials, there are few data to inform the provision of nutrition to infants with HIE during and soon after TH.However, breastfeeding plays a beneficial role in maintaining the structural and functional integrity of the gut. It may help to reduce systemic inflammatory response and positively regulates the microbiota. In many studies it is stated that enteral feeding during TH appears to be safe and feasible. There is insufficient evidence to choose the type of enteral feeding either bolus or continuous during TH. The present study aimed to compare the impact of different types of enteral feeding in infants with HIE receiving TH.
Infants with hypoxic-ischemic encephalopathy (HIE) are at high risk for neurodevelopmental impairment, despite current standards of care. Adjunctive treatments to promote brain repair are needed. The antidiabetic drug metformin has recently been recognized as a neurorestorative agent, but, to date, has not been used in infants. Herein, the investigator describes a clinical trial with the aim of demonstrating the safety and feasibility of metformin use to improve neurodevelopmental outcomes in infants with HIE.
Aneurysmal subarachnoid haemorrhage is a complex pathology, the pathophysiology of which is still imperfectly understood. Its morbidity and mortality remain significant. In addition to the damage sustained by the brain in the immediate aftermath of aneurysmal rupture, which is inaccessible to life-saving treatment, a significant proportion of lesions occur at a distance from the initial event. Delayed cerebral ischaemia is one of the most morbid complications. It combines an inflammatory pattern with vascular dysfunction and neuronal excitotoxicity, leading to avoidable secondary neuronal loss. Vascular dysfunction is mediated by a loss of homeostasis between endothelial cells and figurative blood cells, including platelets. However, the interrelationship between these elements and the precise chronology of the dysfunction remain imperfectly described to date. It therefore seems appropriate to propose temporal monitoring of platelet activation kinetics over time, combined with concomitant collection of markers of endothelial damage, in order to clarify the vascular chronobiology of this pathology.
The goal of this prospective observational study is to assess the effectiveness and performance of Methinks AI stroke imaging software platform in acute Code Stroke patients, and as a comparator to study sites utilizing existing AI imaging stroke platforms. The main question[s] it aims to answer is: • Performance of and outcomes associated with the use of the Methinks AI stroke imaging medical device in real-world clinical practice.
The aim of this study is to evaluate the safety and efficacy of remote ischemic conditioning ( RIC ) in the protection of cerebral ischemia in patients with Takayasu arteritis ( TAK ). The study was designed as a prospective, double-blind, exploratory randomized controlled study. The entire study included a screening period and a treatment observation period ( a total of 24 weeks ). All patients with cerebral ischemia of TAK will be randomly divided into RIC group and sham RIC group at 1:1 ratio. On the basis of receiving the conventional drug therapy, the patients will be treated with RIC or sham RIC treatment twice daily for six month. The clinical data of patients at baseline and each follow-up will be collected, including basic information, disease activity assessment, laboratory indicators, imaging indicators, treatment data, adverse events, etc.The Primary outcome is the mean cerebral blood flow improvement rate ( mCBF-IR ) of TAK patients after 24 weeks-treatment. Secondary endpoints include the incidence of major adverse cerebrovascular events ( MACE ) , the change value of arterial transit time ( ATT ) in pCASL hypoperfusion area compared with baseline, occurrence of RIC-related adverse reactions, the changes of hematological indexes and disease activity score, etc. This study will provide insights into the preliminary proof of principle, safety, and efficacy of RIC in cerebral ischemia in patients with Takayasu arteritis ( TAK ), and this data will provide parameters for future larger scale clinical trials if efficacious.
To compare between Transcranial Ultrasound , MRI and CT in patients with Hypoxic Ischemic Encephalopathyas regards diagnostic accuracy and prognostic value .
In today's medical field, there is a growing emphasis on the development of functional and molecular imaging. Therefore, it has significant technical limitations. To address this issue, this project aims to develop a high-speed multimodal photoacoustic/ultrasound functional imaging system that provides both structural and functional information of tissue and organs, thus enhancing the accuracy of early screening and diagnosis of neonatal cranial lesions. This imaging technology is entirely non-invasive and does not involve ionizing radiation or contrast agents. Products using the same technology have already received FDA approval and entered clinical use in the United States. We develop a new generation of multimodal photoacoustic/ultrasound functional imaging equipment to reveal the physiological characteristics and structural details of neonatal cranial lesions, offering advantages and complementary information compared to traditional medical imaging methods.
The overall goal of this project is to determine if machine learning and analysis of neurospecific biomarkers can enable early detection of upcoming or ongoing cerebral ischaemia in patients suffering from subarachnoid haemorrhage with altered consciousness due to cerebral injury or sedation. Analyses of heart rate variability, electroencephalgraphy,nearinfrared spectroscopy, cerebral autoregulation, and brain injury specific biomarkers in blood and cerebrospinal fluid will be performed.
The current work aims to: The primary aim in this study was to identify the contribution of maternal, pregnancy, birth and neonatal factors to encephalopathic features in new born infants. The secondary aim of this study is to reduce the burden on the country by decreasing the rate of neonatal encephalopathy, decreasing the different grades of neurodevelopmental impairment and improvement the quality of life.
