Filter by:The post-operative delirium picture is a serious and common complication seen after any major surgery, including hepatic resection. Patients who will be planned to undergo donor hepatectomy for liver transplantation will be included in the study. Basic clinical and demographic information of patients undergoes donor hepatectomy will be recorded before surgery. The anatomical parameters such as liver volume, medications performed during the surgery, complications, bleeding amounts, fluids given, blood and blood products, vital signs during surgery, fluid balance, duration of surgery, recovery length at post-operative period, complications after surgery, approaches to complications, analgesics and other medications used, hemogram and other biochemical parameters (electrolytes, albumin, liver frontier tests, etc.), weight status, vital signs, duration of intensive care, post-operative VAS scores, drainage and information such as length of stay, length of hospital stay, the healing time of the wound will also be recorded. During the hospitalization, the delirium status of the patients will be evaluated with a delirium evaluation scale by consultant doctor. Blood will be taken for the measurement of S100β, NSE, and GFAP levels one day before donor hepatectomy and following day of hepatectomy, 3rd day, and 7th day in the post-operative period. The plasma of the blood taken will be separated and stored at -80 0C until working. Laboratory values are taken from the patients before the operation will be recorded over the system. The relationship between the results obtained and the delirium evaluation scores performed on the days followed will be evaluated. This study aims to analyze the delirium incidence and post-operative early S100β, NSE, and GFAP levels within the first week following the hepatectomy performed in live donors for liver transplantation.
This study was carried out to investigate the relationship between pain, anxiety and fatigue and knee position sense, balance and dual task performance during menstrual cycle in females with Multiple Sclerosis (FwMS). In the neurologic group, especially in MS patients, it is well known that disease activity, course, and symptoms can be influenced by the menstrual cycle. Previous studies have reported that the fluctuations of estrogen and progesterone during the menstrual cycle may have an effect on several neurological functions. Menstrual-related symptomatology has primarily been studied as a physiological phenomenon. Increased neurological symptoms, physical disorders and behavioral changes have been reported just before or at the beginning of menstruation in FwMS. For all these reasons,investigators think that relationship between pain, anxiety and fatigue and knee position sense, balance and dual task performance during menstrual cycle in FwMS.
The purpose of this study is to perform a secondary analysis of pre-existing de-identified limited datasets obtained from sites participating in Tier 1 (STUDY20040154: Neurologic Manifestations of COVID 19 in Children) and Tier 2 (STUDY20040278: Neuro COVID - Outcomes). The data will be used to determine the prevalence and severity of neurological symptoms among patients requiring critical care admission for confirmed or suspected novel coronavirus (COVID-19) and to determine the predictors for limitation of care in the study population, as well as, the prognosis of neurologically injured patients admitted to the ICU during the COVID-19 crisis. This study is sponsored by the Pediatric Neurocritical Care Research Group (PNCRG) and sponsored and funded in part by the Neurocritical Care Society.
Covid-19 pandemic now affects more than two million people worldwide. The neurotropism of the virus is assumed by its frequent association with neurological symptoms (anosmia, ageusia, headaches) but the extent of the central or peripheral nervous system involvement and the associated symptomatology remain poorly known for now. The main objective of this study is to describe the neurological and psychiatric manifestations occurring in the context of Covid-19 infection in patients hospitalized or followed-up in the APHP.SU hospital group. A better understanding of the neuropsychiatric impairment related to Covid-19 would improve the management of these patients in the acute phase, and knowledge of subsequent complications would allow adapting their rehabilitation and follow-up. The precise phenomenological description of these manifestations and the imaging, biology and neuropathology data will be compiled from the data collected by the physicians in charge of these patients as part of their inpatient or outpatient care. This study will also allow collecting unusual clinical manifestations from patients followed for neurological or psychiatric pathology in hospital departments and presenting a Covid-19 infection, in order to optimize the reorganization of their management, follow-up and rehabilitation in the epidemic context.
The aim of this study was to investigation of knee position sense, balance, and dual task performance in different phases of menstrual cycle in females with multiple sclerosis. Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) affecting young people and leading to demyelination and neurodegeneration. MS affects females more than males with a ratio approximately of 3:1. Important gender differences in progression and inflammatory activity of disease have been observed. Sex hormones have been thought to play an important role in this condition. It is worth noting however that sex hormones not only affect reproduction (menses/pregnancy), they also have direct effects on the nervous and immune system. In the neurologic group, especially in MS patients, it is well known that disease activity, course, and symptoms can be influenced by hormonal fluctuations in different phases of the menstrual cycle. Previous studies have reported that the variation of estrogen and progesterone during the menstrual cycle may have an effect on several neurological functions. However, these studies are mostly subjective, in the form of patient reports and in limited numbers. Smith and Studd reported that there was a premenstrual increase in disease severity as changes in the Th-1 / Th-2 balance occurred in association with decreased circulating estrogen. Withdrawal of hormones from damaged tissues that affect axonal conduction can explain the change in disease activity, course symptoms during the menstrual cycle in female with MS. For all these reasons,investigators think that different phases of menstrual cycle change position sense, balance, and dual task performance in females with MS. Considering hormonal fluctuations occurring in the menstrual cycle, is an important criterion for organizing the rehabilitation program and evaluation in terms of physiotherapy.
Vasoactive intestinal peptide (VIP) is a peptide of 28 amino acid residues that belongs to the glucagon/secretin superfamily of peptides. Along with other neuropeptides, such as calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP), it is released from the trigeminal afferents and exerts a strong vasodilating activity on the cranial vasculature. Especially, it shares 70% structure with PACAP and acts on the same receptors. But, unlike it, VIP cannot induce a long-lasting vasodilation and has a modest capability to induce migraine attacks. Whether it may induce migraine-like attacks in migraine patients, as a twenty-minute infusion of PACAP, is unknown.
Prospective, multi-site, single-arm study to evaluate the diagnostic yield of cWGS in adults with neurological disorders. A single cohort naive of genetic testing will receive standard of care testing for 180 days followed by cWGS. The cohort will be followed for a total of 365 days following enrollment.
Uremic encephalopathy is an organic brain disorder may be frequently seen in patients with acute or chronic renal failure. Certain neurological symptoms can be found under clinical glomerular filtration rate of 15 ml/minutes. The above mentioned neurological disorders can be due to uremic toxins as well as many other reasons such as metabolic and hemodynamic disturbances, inflammation, or oxidative stress. Most frequent symptoms are impaired consciousness, lethargy, cranial nerve involvement, nystagmus, dysarthria, and even coma and death. Brain tissue may receive damage and some secondary biomarkers may appear in case BUN (Blood Urea Nitrogen) level is >175 mg/dl together with neuroinflammation. Although hemodialysis is a temporary solution in terms of treatment, these symptoms may be reversible in the long-run with organ transplantation. A rigorous neurological assessment before transplantation is important for identifying the severity and distribution of the neurological disorder as well as defining the abnormalities that are responding to the current treatments and foreseeing potential postoperative prognosis. S100β is excreted by astrocytes in brain damage cases. S100β level rises when brain damage starts, thus it may be used in the prognosis of brain damage in its early period. Neuron-specific enolase (NSE) functions as intracytoplasmic enzyme and serum level rises in neuron damage. Glial fibrillary acidic protein (GFAP), on the other hand, is the intermediary filament cytoskeleton protein found in astrocytes. It has the same root structure with S100β. The purpose of this study is to assess neurological damage by looking at the levels of S100β, NSE and GFAP in patients who underwent kidney transplantation and to analyze the impacts on the prognosis.
Stroke is the 4th leading cause of mortality in Hong Kong. It also carries considerable socioeconomical consequences due to disability. Ischemic stroke can be classified by the TOAST classification, which includes large artery atherosclerosis, cardioembolism, small-artery occlusion and other causes (1). Among which, intracranial atherosclerosis (ICAS) had been major cause of acute ischemic stroke (AIS) in the Asia Pacific. It was estimated as high as 24.1% of AIS or transient ischemic attacks (TIAs) were attributed to ICAS in China (2). Management of ICAS related strokes has been challenging owing to its high rate of recurrence despite medical therapy. Recent randomized clinical trial suggested that aggressive medical therapy may result in reduction in recurrence compared with historical cohorts (3). Our group has previously observed a 2.5-fold increase in atrial fibrillation related stroke over a 15-year period (4). The inverstigator also observed a decline in ICAS related AIS as well as its recurrent stroke risk throughout the recent years. Possible mechanisms include better management of metabolic risk factors and aggressive secondary prevention. Other possible reasons are increased atrial fibrillation (AF), small vessel disease (SVD) or other stroke mechanisms. This study is aim to find the evolution of different stroke subtypes in relation to the characteristics of our stroke population over a 15-year period. This may influence territorial prevention strategy.
The European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM) joint guidelines for post-resuscitation care recommend a multimodal approach to prognostication of neurological outcome. However, head computed tomography (CT) which is commonly used for predicting long-term neurological outcome after cardiac arrest has not yet been examined prospectively in a clinical trial. The primary purpose of the TTM-2 CT-substudy is to prospectively investigate and compare various methods of diagnosing generalized oedema on CT after cardiac arrest and it´s ability to predict long-term neurological outcome.
