Filter by:The goal of this clinical trial is to evaluate the effects of minimal enteral nutrition (MEN) on mesenteric blood flow and oxygenation with Doppler USG and Near Infrared Spectroscopy (NIRS) during therapeutic hypo¬thermia (TH) in babies with hypoxic ischemic encephalopathy. The main question it aims to answer is: 1- How do the mesenteric blood flow and oxygenation get affected with MEN during TH? Participants will be either fed with MEN during TH or given placebo.
The main objective of this research is to measure the Doppler signal by the ultrasonic patch. Blood flow measurement is critical for vasospasm, stroke, and embolism monitoring on patients in the ICU or understanding the neurovascular coupling on different subjects. Currently, A conventional transcranial Doppler (TCD) probe is widely used for these applications. A headset design must be applied and fixed on the participants to obtain stable blood flow spectra. However, the TCD headset is operator dependent. The operator needs to be a trained expert and hold the ultrasound probe to get accurate blood flow velocity information. The stretchable and wearable non-invasive ultrasonic patch can not only free the operator's hands but can also provide long-term continuous monitoring, which is not possible by using the current operator-dependent ultrasound machine. The device can be conformal to the skin and attached to the skin surface.
Sepsis-associated brain dysfunction (SABD)with increased intracranial pressure is a complex pathology that can lead to unfavourable outcome. Although direct measurement of intracranial pressure using an intra-ventricular catheter remains the gold standard, it is burdened with potential serious complications due to its invasiveness. Ultrasonic measurement of optic nerve sheath diameter (ONSD) is a non-invasive method for ICP monitoring. Screening for SABD is crucial for early diagnosis and management, measurement of ONSD can detect elevated intracranial pressure in septic patients. Intracranial hypertension in septic patients might be a sign of SABD. Using ONSD for SABD screening requires further research. So, we hypothesized that ONSD could be used as an objective screening tool to predict and early diagnose SABD in adult septic patients.
PROMISE aims at identifying novel diagnostic and prognostic circulating biomarkers for patients with acute stroke and at informing on crucial yet undetected pathophysiological mechanisms driving outcome after stroke by enriching all phenotypic information available from clinical routine with in-depth quantification of the circulating proteome and metabolome as well as other entities.
Immunotherapy with chimeric antigen receptor (CAR) T cell therapy can cause immune effector cell-associated neurotoxicity syndrome (ICANS). However, the molecular mechanisms leading to ICANS are not well understood. In this study, the investigators plan to examine the role of microglia as the primary parenchymal immune cells of the central nervous system (CNS) during ICANS in human samples. The samples will be analyzed using imaging-mass-cytometry-based analysis (IMC). Single-cell data will be obtained through machine learning supervised segmentation of IMC data. Single-cell marker expression in all cells and in microglia (Iba1+ cells) will be analyzed in patients with ICANS.
The goal of this observational study is to compare the differences in the features of cerebral multifrequency EIT(cMFEIT) images between healthy subjects and patients with brain diseases and to explore the possibility of applying multifrequency EIT to intracranial abnormality detection.16 healthy volunteers and 8 patients with brain diseases were recruited as experimental subjects, and the cerebral EIT data of 9 frequencies in the range of 21 kHz - 100 kHz of all subjects were acquired with an EH-300 MFEIT system.
This study aims to investigate whether a live stream video between the on-call neurologist and the emergency medical services is feasible.
The transition period to full oral feeding in infants with perinatal asphyxia is important in predicting long-term outcomes. The transition to independent oral feeding is accepted as a discharge criterion by the American Academy of Pediatrics, and the long transition from tube feeding to oral feeding prolongs the discharge process. Prolonged transition to oral feeding increases maternal stress as it delays gastrointestinal problems, mother-infant interaction and attachment, as well as increasing health expenditures. Due to long-term feeding tube use; Infection, leakage, delay in wound healing, trauma caused by repeated placement, as well as oral reluctance are observed. In asphyxia infants, in whom oral-motor dysfunction is common, the transition to oral feeding takes a long time and tube feeding support is required. The effect of hypothermia, which is a general therapeutic intervention that reduces the risk of mortality and morbidity in infants with asphyxia, on oral feeding has been previously studied and shown to have a positive effect. They also found that MR imaging in infants with asphyxia and the need for gastrostomy and tube feeding in those with brainstem involvement were associated. Various interventions that affect the transition to oral nutrition positively and shorten the discharge time are included in the literature. Stimulation of non-nutritive sucking (NNS) is the most frequently preferred method among these interventions. It has been shown in studies that there are no short-term negative effects of NNS stimulation with the help of a pacifier or gloved finger, and some clinical benefits such as better bottle feeding performance, acceleration of discharge and transition to oral feeding. The effect of the NNS stimulation method, which has been shown to be effective in preterm infants with large-scale randomized controlled studies, is not known exactly. The aim of this study is to examine the effect of NNS stimulation applied to oral feeding, feeding skills, weight gain and discharge in asphyxia infants receiving hypothermia treatment.
Studying the effect of passive versus Blanket roll III modality of therapeutic hypothermia (TH)on myocardial function of asphyxiated neonates through using tissue Doppler (TD).
In a randomized, placebo-controlled trial, 35 patients with HIBI were randomly designated to receive either MLC901 or placebo capsules over six months. We evaluated patients in two groups by modified Rankin Scale (mRS) and Glasgow outcome scale (GOS) to examine their state of disability and recovery
