Filter by:Determination of autoantibodies against fragments derived from neurons, glia, and myelin sheath is instrumental in aiding diagnosis, differential diagnosis, as well as determining disease status of neuromyelitis optica spectrum disorders (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), autoimmune encephalitis (AE). Cell based assay (CBA) has been frequently recommended to detect autoantibodies of neuroantigens in the aforementioned neurological disorders. However, antibodies with low abundance or low affinity often fall beyond the threshold of CBA and pose significant challenges in practice. To this end, the investigators adopted a tyramide signal amplification (TSA) technology with the basis of CBA to improve sensitivity. The preliminary results suggest that this TSA-CBA platform is superior to conventional CBA in registered signals of the titer autoantibodies. In elevating the sensitivity, TSA-CBA also preserves antigen confirmation. This prospective study is launched to compare the sensitivity, specificity, clinical correlation between CBA and CBA-TSA, in determining autoantibodies against aquaporin 4 (AQP4-IgG), myelin oligodendrocyte glycoprotein (MOG-IgG), N-methyl-D-aspartate receptor (NMDAR-IgG) in a multicenter, double-blind setting.
Self-testing with easy-to-use rapid diagnostic tests (RDTs) has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages. Self-testing has also been effectively used to reach key populations who may not be covered by traditional healthcare programs, such as persons who inject drugs and men who have sex with men. In Malaysia, HIV self-testing has been shown to have moderate to high levels of acceptability, depending on the population, test used, and test delivery framework. In the present study we aim to evaluate the acceptability and impact of an online program enabling home-based hepatitis C virus (HCV) self-testing in Malaysia.
To achieve the goal of elimination of hepatitis C infection in Pakistan, the strategy of elimination needs to be increasingly directed towards case finding through mass screening in rural or peri-urban communities to identify and treat those not yet aware of their infection. Self-testing (ST) with easy-to-use rapid diagnostic tests has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages. In the present study we aim to evaluate the acceptability and impact of a program enabling home delivery of hepatitis C virus (HCV) self-testing in the Malir district, Karachi division, Pakistan.
Self-testing with easy-to-use rapid diagnostic tests has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages.7 Self-testing has also been effectively used to reach key populations who may not be covered by traditional healthcare programs, such as persons who inject drugs (PWID) and men who have sex with men (MSM). In Georgia, HIV self-testing has been offered to MSM through an online platform promoting their uptake.11-12 In the present study aims to evaluate the acceptability and impact of using an online platform to enable home delivery of HCV self-testing in Georgia for PWID and MSM.
This study is exploratory and examines whether the refraction results obtained from a novel optical device yields results similar to the ophthalmic refraction measurements obtained from an autorefractor in children.
Background: Due to anatomical restrictions, the inflammatory response to intra-cerebral bacterial infections exposes swollen brain tissues to pressure and ischemia, resulting in life-threatening damage. However, diagnosing meningitis in patients after neurosurgery is complicated, due to brain tissue damage and changes in cerebrospinal fluid (CSF) caused by surgery. Hepatocyte growth factor (HGF) is a local, acute-phase protein. Previous studies on community-acquired septic meningitis reported high levels of intrathecal-produced HGF. Aim: The aim of present study is to evaluate a new platform for qualitative determination of HGF in body fluids and revealing the site of injury. Method: Based on a reverse-methachromacy method, strips are prepared. The surface on the strip changes colour to blue upon contact with HGF. Plan: CSF, urine and sputum of patients that develop fever post neurosurgery are analysed with the test and the results compared with conventional diagnostic methods. Clinical value: A rapid, equipment-free test gives the opportunity to identify the infectious focus in the infected organ long before culture results are available.
The emergency setting for acute neurological conditions, such as stroke, is peculiar due to time pressure and limited resources for further diagnostics. Clinical skills are essential for swift and accurate bedside diagnosis and thus are the basis for early and correct treatment. This is especially evident in the context of computed tomography being the standard neuroimaging method world-wide with its limitations for detecting smaller infarcts, strokes in the posterior fossa and reduced sensitivity for stroke mimics, such as epileptic seizures or migraine aura. To date, the accuracy of clinical bedside diagnosis of stroke by neurologists verified by magnetic resonance imaging (MRI) in the emergency setting has not been studied in detail. In order to improve clinical diagnosing and future treatment it is essential to quantify the accuracy of clinical diagnosis of stroke in the emergency setting ("how good are neurologists?") and to assesses whether there are any differences between experienced staff neurologists and junior physicians.
