Elevated miR-9 in Cerebrospinal Fluid Is Associated with Poor Functional Outcome After Subarachnoid Hemorrhage

This study evaluated microRNA (miRNA) changes in cerebrospinal fluid (CSF) and their association with the occurrence of delayed cerebral ischemia (DCI) and poor functional outcome after SAH. Forty-three selected miRNAs were measured in daily CSF samples from a discovery cohort of SAH patients admitted to Rigshospitalet, Copenhagen, Denmark, and compared with neurologically healthy patients. Findings were validated in CSF from a replication cohort of SAH patients admitted to Massachusetts General Hospital, Boston, Massachusetts. The CSF levels of miRNA over time were compared with the occurrence of DCI, and functional outcome after 3  months. miRNAs were quantified in 427 CSF samples from 63 SAH patients in the discovery cohort, in 104 CSF samples from 63 SAH patients in the replication cohort, and in 11 CSF samples from 11 neurologically healthy patients. The miRNA profile changed remarkably immediately after SAH. Elevated miR -9-3p was associated with a poor functional outcome in the discovery cohort (p

Authors: Meregildo ED Abstract Neurocysticercosis (NCC) is a global health problem. In more developed countries, NCC is mainly a disease affecting immigrants. In developing countries, NCC is the most common parasitic disease of the nervous system and the main cause of acquired epilepsy. NCC is also an unrecognized cause of strokes and could account for 4%-12% of strokes. Here, I report a case of a 58-year-old woman who presented to the emergency department (ED) with severe headache, vomiting, and sudden loss of consciousness. Multiple NCC and Fisher grade 4 aneurysmal subarachnoid hemorrhage (SAH) were demonstrated...

The current COVID-19 pandemic has recently brought to attention the myriad of neuro- logic sequelae associated with Coronavirus infection including the predilection for stroke, particularly in young patients. Reversible cerebral vasoconstriction syndrome (RCVS) is a well-described clinical syndrome leading to vasoconstriction in the intracra- nial vessels, and has been associated with convexity subarachnoid hemorrhage and oc- casionally cervical artery dissection. It is usually reported in the context of a trigger such as medications, recreational drugs, or the postpartum state; however, it has not been described in COVID-19 infection.

Aneurysmal subarachnoid hemorrhage (SAH) patients require frequent neurological examinations, neuroradiographic diagnostic testing and lengthy intensive care unit stay. Previously established SAH treatment protocols are impractical to impossible to adhere to in the current COVID-19 crisis due to the need for infection containment and shortage of critical care resources, including personal protective equipment (PPE). Centers need to adopt modified protocols to optimize SAH care and outcomes during this crisis.

CONCLUSIONS: Patients with diabetes mellitus were vulnerable to hemorrhagic transformation, whereas those who underwent several attempts of thrombectomy were susceptible to isolated subarachnoid hemorrhage. Both hemorrhage types worsened the functional outcome. Treatment with the stent retriever was significantly associated with postprocedural isolated subarachnoid hemorrhage.

Authors: Susmitha K, Chandrasekhar V, Kiran G, Divya A, Rani GS, Sarangapani M Abstract Stroke is becoming a main cause of early death and disability in developing countries like India, and it is mostly enhanced by increased predominance of major risk factors. A detailed knowledge about the nature and magnitude of the stroke cases in this particular area is not only important for acute treatment but also it helps to prevent hospital admissions due to reoccurring stroke. The present study was conducted in the Department of Stroke at MGM Hospital, Warangal, India, to study the patterns of stroke admissions. All the c...

CONCLUSION: This study describes the current status of acute stroke care in Korea. Despite quite acceptable quality of stroke care, it suggests regional and hospital disparities. Expansion of stroke units, stroke center certification or accreditation, and connections between stroke centers and emergency medical services are highly recommended.

Authors: Gattellari M, Goumas C, Jalaludin B, Worthington JM Abstract OBJECTIVES: Epidemiological trends for major causes of death and disability, such as stroke, may be monitored using administrative data to guide public health initiatives and service delivery. METHODS: We calculated admissions rates for ischaemic stroke, intracerebral haemorrhage and subarachnoid haemorrhage between 1 January 2005 and December 31st, 2013 and rates of 30-day mortality and 365-day mortality in 30-day survivors to 31 December 2014 for patients aged 15 years or older from New South Wales, Australia. Annual Average Percentage...

AbstractCoronavirus disease 2019 (COVID-19), a disease caused by the novel betacoronavirus (SARS-CoV-2), has become a global pandemic threat. The potential involvement of COVID-19 in central nervous system (CNS) has attracted considerable attention due to neurological manifestations presented throughout the disease process. In addition, SARS-CoV-2 is structurally similar to SARS-CoV, and both bind to the angiotensin-converting enzyme 2 (ACE2) receptor to enter human cells. Thus, cells expressing ACE2, such as neurons and glial cells may act as targets and are thus vulnerable to SARS-CoV-2 infection. Here, we have reviewed ...

CONCLUSIONS: The incidence of SAH appears to have decreased in recent years, with SAH-I comprising 17.9% of the cases. Patients with SAH-I have better prognosis and lower risk of complications, highlighting the benignity of SAH-PM. PMID: 32457002 [PubMed - as supplied by publisher]
