Identification of a Nuclear Localization Signal (NLS) in Human Transcription Elongation Factor ELL2.

ELL2 is a transcription elongation factor suppressing transcriptional pausing of RNA polymerase II, thereby enhancing gene expression. In accordance with the nuclear localization of ELL2, the protein is supposed to carry out its function in promoting transcription in the nucleus. Yet, it is unknown whether ELL2 carries a nuclear localization signal (NLS).

The tyrosine kinase Yes1 is a druggable host factor of HEV.

Background: HEV is a positive-sense, single-stranded RNA virus of the Hepeviridae family. Although HEV accounts for more than 3 million symptomatic cases of viral hepatitis per year, specific anti-HEV therapy and knowledge about HEV pathogenesis are scarce.

Methods: To gain a deeper understanding of the HEV infectious cycle and guide the development of novel antiviral strategies, we here used an RNAi mini screen targeting a selection of kinases, including mitogen-activated protein kinases, receptor tyrosine kinases, and Src-family kinases.

Methotrexate for the neurologist.

The use of methotrexate in clinical practice has expanded significantly in recent years, as an effective chemotherapeutic agent as well as disease-modifying treatment for conditions such as rheumatoid arthritis, psoriasis and Crohn's disease. It is also used as a steroid-sparing agent for a range of inflammatory diseases of the central and peripheral nervous systems. Clinical neurologists must, therefore, know how to start and uptitrate methotrexate, its monitoring requirements and its potential toxicities.

Using Mixed Reality Headsets to Deliver Remote Bedside Teaching During the COVID-19 Pandemic: Feasibility Trial of HoloLens 2.

Background: COVID-19 has had a catastrophic impact in terms of human lives lost. Medical education has also been impacted as appropriately stringent infection control policies precluded medical trainees from attending clinical teaching. Lecture-based education has been easily transferred to a digital platform, but bedside teaching has not.

Willingness to receive a COVID-19 vaccine in people with multiple sclerosis - UK MS Register survey.

Background & Methods: We conducted an online COVID-19 survey as the vaccines became available, utilising the UK MS Register, to understand people with multiple sclerosis (pwMS) views on COVID-19 vaccination and the subsequent vaccine uptake rates.

Results & Conclusion: 94.4% of 3191 pwMS surveyed indicated they would get a COVID-19 vaccine, while 5.

A Diagnosis of Multiple Sclerosis Following Whiplash Injury: Is There a True Association?

We report a case of a previously well, 25-year-old Caucasian female whose diagnosis of multiple sclerosis (MS) followed significant trauma. Her symptoms and signs developed quickly and satisfied the criteria for rapidly evolving relapsing-remitting MS. She was started on natalizumab (Tysabri) and was stabilized.

Concurrent sodium channelopathies and amyotrophic lateral sclerosis supports shared pathogenesis.

Amyotrophic lateral sclerosis (ALS) is an invariably fatal adult-onset neurodegenerative disorder; approximately 10% of ALS is monogenic but all ALS exhibits significant heritability. The skeletal muscle sodium channelopathies are a group of inherited, non-dystrophic ion channel disorders caused by heterozygous point mutations in the gene, leading to clinical manifestations of congenital myotonia, paramyotonia, and periodic paralysis syndromes. We provide clinical and genetic evidence of concurrence of these two rare disorders which implies a possible shared underlying pathophysiology in two patients.

CSF lactate.

Lactate is produced from anaerobic glycolysis, which occurs in most tissues in the human body. Blood lactate is tested in most physiologically unwell patients in the Emergency Department and helps to guide treatment and prognosis. Cerebrospinal fluid (CSF) lactate, however, is not often measured.

Effect of Antibiotic Discontinuation Strategies on Mortality and Infectious Complications in Critically Ill Septic Patients: A Meta-Analysis and Trial Sequential Analysis.

Objective: To investigate methods of antibiotic duration minimization and their effect on mortality and infectious complications in critically ill patients.

Data Sources: A systematic search of PubMed, Embase (via Ovid), clinicaltrials.gov, and the Cochrane Central Register of Controlled Trials (via Wiley) (CENTRAL, Issue 2, 2015).

A black mould death: A case of fatal cerebral phaeohyphomycosis caused by .

Cladophialophora bantiana is a neurotropic mould and primary cause of cerebral phaeohyphomycoses, which presents with brain abscesses in both immunocompromised and immunocompetent individuals. It is associated with high mortality due to delay in diagnosis and absence of standardised therapy. We present a case of fatal cerebral phaeohyphomycosis in a 67-year-old Caucasian man.

Anti-NMDAR encephalitis complicating pregnancy.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis was first reported in 2005 in four patients with ovarian teratomas; there have been many further cases reported since the antigen for the NMDAR antibody was confirmed in 2007. Patients characteristically have a well-defined set of features, characterised by psychiatric disturbance, seizures and cognitive disturbance, followed by movement disorders, disorders of consciousness and dysautonomia. To date, 14 cases of NMDAR encephalitis have been described in the context of pregnancy.

Neuromyelitis optica spectrum disorder related tonic spasms responsive to lacosamide.

Paroxysmal tonic spasms [PTS] are common in patients with neuromyelitis optica spectrum disorder (NMOSD).1 2 In patients with demyelinating disease, PTS can significantly reduce the quality of life, limit activities of daily living and the rehabilitative process following an acute relapse 3. As in patients with multiple sclerosis (MS), paroxysmal tonic spasms in NMOSD usually respond well to treatment with carbamazepine.

Antecedent anti-NMDA receptor encephalitis in two patients with multiple sclerosis.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disorder characterised by psychiatric symptoms, movement disorder and seizures often evolving into a severe encephalopathy. An overlap has recently been recognised between anti-NMDAR encephalitis and inflammatory demyelinating disorders, particularly neuromyelitis optical spectrum disorder (NMOSD). In this case report, we describe two patients with an initial presentation consistent with anti-NMDAR encephalitis who have subsequently developed relapsing-remitting multiple sclerosis (MS) and discuss the literature pertaining to potential overlap between NMDAR encephalitis and inflammatory demyelinating disorders.

A Rare Case of Bilateral Optic Neuritis and Guillain-Barré Syndrome Post Infection.

Neurological complications are the most commonly encountered extra-pulmonary manifestation of infection with . Here the authors report the case of a 39-year-old woman who was admitted with acute-onset bilateral visual loss coinciding with ascending numbness. Clinical examination, neurological imaging, and nerve conduction studies revealed a syndrome of bilateral optic neuritis and Guillain-Barré syndrome (GBS).

Severe Hemorrhagic Transformation after Thrombolysis for Acute Ischemic Stroke Prevents Early Neurological Improvement.

Background: Intravenous thrombolysis can improve neurological outcomes after acute ischemic stroke (AIS), but hemorrhagic transformation (HT) of the infarct remains a risk. Current definitions for symptomatic intracerebral hemorrhage (ICH) all entail that there be some degree of associated neurological deterioration. However, early deleterious effects of secondary ICH might also be manifested as reduced neurological improvement.

A Retrospective Cohort Study on the Use of Intravenous Thrombolysis in Stroke Mimics.

Background: The urgency of intravenous thrombolysis in acute ischemic stroke can lead to inadvertent thrombolysis of patients with nonstroke diagnoses (stroke mimics), increasing the risk of adverse events. The objectives of this study were to compare thrombolysed acute ischemic stroke and stroke mimic cases based on demographic factors, physiological parameters, radiological findings, and clinical presentation, and to evaluate the clinical implications of thrombolysing stroke mimics.

Methods: A retrospective analysis of a single-center database of all thrombolysed strokes and mimics over a period greater than 3 years.
