Based on emerging experience and trials from countries affected early by the COVID-19 (COV19) pandemic, there is evidence that a subgroup of severely affected people develop a hyperinflammatory (HI) syndrome (COV-HI). Trials are in progress of cytokine inhibition and other immune modulation to treat COV-HI. This proposal aims to use a rapidly executed cohort study to characterise the clinical phenotypes of COV-HI in patients in the UK through an established and nimble network of clinicians and scientists with broad experience of identifying and treating HI. The aim is to confirm the COV-HI clinical phenotype and using routine data to try to infer the inflexion point where COV-HI emerges. This would enable refinement of the proposed treatment algorithm and translates to routine clinical practice to improve the outlook for COV-HI.
This is a parallel group double-blind, randomized-controlled trial with 1:1 randomization ratio which will be conducted over a period of 6 months to study the effect of vitamin C administration on the amount of noradrenaline given post-operatively to patients after CPB. Two groups will be included; Group (A) patients undergoing open heart surgeries who will receive IV ascorbic acid (treatment group) and Group (B) patients undergoing open heart surgeries who will not receive ascorbic acid or will receive a placebo (control group). Each patient will be subjected to assessments of the doses of noradrenaline given from the end of surgery until weaning as well as hemodynamics in the first 2 hours and then at intervals of 6 hours up to 3 days following surgery.
This study aims to analyze the effectiveness and safety of Avigan® (favipiravir) compared to Oseltamivir as an adjuvant therapy among adult COVID-19 patients. This study will be conducted in a hospital setting, recruiting adult COVID-19 patients with mild, moderate, and severe symptoms. Subjects will be randomly given Favipiravir or Oseltamivir as an adjuvant therapy to standard COVID-19 treatment. Patients will be followed up for 21 days after the first dose of intervention given. The primary outcomes of this study are the improvement of radiology results and RT PCR negative conversion during follow up. The secondary outcomes are adverse events, hospital length of stay (LOS), and Case fatality rate (CFR)
this work is looking for comparison between the effect of tramadol versus morphine on PD1 and PD1-ligand in patients with chronic cancer pain
The SARS-CoV-2 (COVID-19) infection is causing a global pandemic and a major health crisis in France. Immunity is the body's ability to defend itself against infectious agents such as viruses. The progressive acquisition by a large part of the population of immunity to defend itself against the COVID-19 virus is one of the main mechanisms by which a resolution of this pandemic is hoped for. Recovery from infection and protection from the virus is likely to depend on the development of antibodies (proteins produced by the body to neutralize infectious agents) and T-cells (a type of white blood cell in the immune system) that can stop the virus from multiplying and killing it. To date, the way and speed at which the T-lymphocytes active against the virus appear are not known. The development of biological tests to detect T-cells active against the virus in the blood of infected patients is therefore necessary. In this context, we propose you to participate in a study that will study the immune system's response against the sars-CoV-2 virus during and after COVID-19 infection.
The purpose of this study is to investigate if a person with weakness or paralysis in one or both arms, can use the NuroSleeve combined powered arm brace (orthosis) and muscle stimulation system to help restore movement in one arm sufficient to perform daily activities. This study could lead to the development of a product that could allow people with arm weakness or arm paralysis to use the NuroSleeve and similar devices to improve arm health and independent function.
This study aims at assessing the proportion of patients suffering from neuro-visual troubles (visual-spatial and/or visual-perceptual ), after cerebellar strokes.
Non-invasive brain stimulation (tDCS) such as transcranial direct current stimulation (TDCS) has been reported to be effective in improving motor performance and safe in participants with cerebral infarction. However, few studies have been done in participants with acute cerebral infarction. In this study, the investigators want to see the effect of tDCS in acute cerebral infarction. the investigators perform tDCS in participants with acute ischemic stroke within 48 hours after stroke onset and the investigators measure motor weakness and function at early phase as well as at 3 months.
Sleep quality affect working and learning performance; poor quality of sleep is one of the common problems of modern people. Traditionally, polysomnography is a recognized standard for sleep quality assessment. Subjects are put adhesive electrodes, chest and abdomen band, oximetery, and oronasal cannula and stay in certified sleep laboratory for monitoring. These sensors setup are cumbersome and be likely to induce discomfort. An alternative to assess the quality of sleep is actigraphy, which allows users to wear for more than two weeks. In recent years, many of the devices, which often measure physiological signals, are prevailing to make long-term sleep monitoring feasible, but its accuracy and effectiveness still need to be verified. Obstructive sleep apnea (OSA) is a common disorder characterized by intermittent hypoxia and sleep fragmentation. OSA is associated with cardiovascular morbidity and mortality, metabolic dysregulation, and neurocognitive dysfunction, which results in the negative impact on prognosis. PSG is the gold standard for OSA diagnosis which is expensive and less accessible. Therefore, modality other than PSG is necessary to speed up diagnosis and treatment. Center of Sleep Disorder in National Taiwan University Hospital has been operated since June 2006. Up to Dec.2015, totally 8,819 patients have been referred for sleep studies (NTUH cohort) where 1,435 patients are under long-term CPAP and 396 patients are under MAD. Using data from 4,618 patients in NTUH cohort, we have already established an OSA prediction mode (apnea-hypopnea index, AHI≥5/hr) with accuracy 82.37% (sensitivity 87.03%, positive predictive value 91%). Regarding the molecular mechanism, our previous study showed that by plasma metabolomics profiling, we could identify candidate metabolites associated with OSA severity. The 11 candidate metabolites were identified by comparing profiling in 100 patients with AHI <15/hr and with AHI≥ 15/hr, respectively. Six identified metabolites were selected to establish an AHI prediction model which gave sensitivity 66%, specificity 72%, and AUROC 0.736. Furthermore, 15 plasma metabolites associated with excessive daytime sleepiness (EDS) or polysomnographic parameters were identified. Among those metabolites, L-Kynurenine and g-Glutamylleucine were metabolites associated with EDS which generated the AUROC to EDS prediction as 63% in study group and 76.7% in validation group. The "LARGAN"ECG Holter for diagnosis of sleep disorder has been set up by LARGAN-health. It aims on population with simple diagnosis of sleep disorder. Combining the "LARGAN"ECG Holter provides the diagnosis and solution of sleep disorder, sleep tracking, and education. This devices is almost set and needs the input from general population to validate the accuracy. The trial, which includes questionnaires, Actigraph devices, 24-hr BP and "LARGAN"ECG Holter for long-term home sleep monitoring, is proposed to allow users to detect potential subjects who have sleep disorders by using the ECG Holter. The aims of the present project include: (1) All 190 voluntary. Recruit 30 voluntary participants from patients with mild OSA (AHI≥5-15/hr), 160 for each voluntary participants from patients with moderate OSA (AHI≥15-30/hr) and severe OSA (AHI≥30/hr) to validate agreement of sleep efficiency via this trial, Actigraph devices and ECG Holter for 9 days, and 24 hour blood pressure for one day. (2) All participants will take an overnight PSG test, blood sampling, basal metabolism measurement, Actigraph devices, ECG Holter, body composition and E-Prime at the sleep center to validate the performance of this system on diagnosis of OSA in low risk population. (3) Analyze the of PSG parameters in both low and high risk population (to build up the out of center devices for OSA home testing). (4) Integrate the clinical parameters and plasma metabolic profile, before and after treatment, to identify factors associated with OSA related sequels and long-term prognosis.
The purpose of this study is to assess the effects of tDCS in combination with TUS for the treatment of pain in subjects with Carpal Tunnel Syndrome. The investigators hypothesize that there will be a decrease in pain levels with active stimulation, when compared to sham stimulation.
