Background: Several prehospital scales have been designed to aid paramedics in identifying stroke patients in the ambulance setting. However, external validation and comparison of these scales are largely lacking.

Aims: To compare all published prehospital stroke detection scales in a large cohort of unselected stroke code patients.

Article Synopsis
  • The study compares two strategies for managing high blood pressure in patients with ischaemic strokes who are eligible for intravenous thrombolysis: an active blood-pressure-lowering strategy and a conservative, non-lowering approach.
  • Conducted across 37 Dutch stroke centers, it involved eligible adults with elevated blood pressure and aimed to assess functional outcomes at 90 days, alongside secondary measures like complications and treatment timing.
  • The trial started in January 2015 but was prematurely halted due to low patient enrollment and lack of funding.

Background: It is unknown if ambulance paramedics adequately assess neurological deficits used for prehospital stroke scales to detect anterior large-vessel occlusions. We aimed to compare prehospital assessment of these stroke-related deficits by paramedics with in-hospital assessment by physicians.

Methods: We used data from 2 prospective cohort studies: the LPSS (Leiden Prehospital Stroke Study) and PRESTO study (Prehospital Triage of Patients With Suspected Stroke).

Background And Purpose: Direct transportation to a thrombectomy-capable intervention center is beneficial for patients with ischemic stroke due to large vessel occlusion (LVO), but can delay intravenous thrombolytics (IVT). The aim of this modeling study was to estimate the effect of prehospital triage strategies on treatment delays and overtriage in different regions.

Methods: We used data from two prospective cohort studies in the Netherlands: the Leiden Prehospital Stroke Study and the PRESTO study.

Background: Leptospirosis is a bacterial infection which may cause multiple non-specific symptoms. Transmission of the disease can occur via rats or surface water infected by rats. The Netherlands have seen a record number of cases of leptospirosis in 2019.

Importance: The efficacy of endovascular thrombectomy (EVT) for symptomatic large anterior vessel occlusion (sLAVO) sharply decreases with time. Because EVT is restricted to comprehensive stroke centers, prehospital triage of patients with acute stroke codes for sLAVO is crucial, and although several prediction scales are already in use, external validation, head-to-head comparison, and feasibility data are lacking.

Objective: To conduct external validation and head-to-head comparisons of 7 sLAVO prediction scales in the emergency medical service (EMS) setting and to assess scale feasibility by EMS paramedics.

Background: An important percentage of subjects diagnosed with chronic upper airway disease report alcohol-induced worsening of their symptoms. The prevalence and characteristics of respiratory reactions provoked by alcohol-containing drinks have not been fully investigated yet.

Objective: The aim of this study was to estimate the prevalence and characteristics of alcohol hyper-responsiveness in patients with chronic airway disease and healthy controls.

Background: In multiple sclerosis patients, the persistence of, and adherence to, disease-modifying treatment are often insufficient. The degree of persistence and adherence may relate to the care received from various disciplines.

Methods: In an observational study of 203 patients treated with glatiramer acetate 20 mg subcutaneous daily, we assess the persistence and adherence in relation to the amount of care received in various disciplines.

Immunoglobulin E (IgE) can be highly elevated in the airway mucosa independently of IgE serum levels and atopic status. Mostly, systemic markers are assessed to investigate inflammation in airway disease for research or clinical practice. A more accurate but more cumbersome approach to determine inflammation at the target organ would be to evaluate markers locally.

There is no evidence that centralisation of acute stroke care will lead to more performance of thrombolysis, in the Netherlands, to a reduction in the 'door-to-needle' time or a better outcome after stroke. The implementation of far-reaching changes in acute stroke care in the Netherlands would be dangerous, and would not lead to better and cheaper, but to worse and more expensive care.

Background: People who have had a transient ischaemic attack (TIA) or non-disabling ischaemic stroke have an annual risk of major vascular events of between 4% and 11%. Aspirin reduces this risk by 20% at most. Secondary prevention trials after myocardial infarction indicate that treatment with vitamin K antagonists is associated with a risk reduction approximately twice that of treatment with antiplatelet therapy.

Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system, for which no definitive treatment is available. Most patients start with a relapsing-remitting course (RRMS). Disease-modifying drugs (DMDs) reduce relapses and disability progression.

This review addresses 2 fields: secondary prevention after cerebral ischaemia of cardiac origin (CICO) and that after cerebral ischaemia of arterial origin (CIAO). The major trial after CICO is the EAFT that showed the superiority of mild oral anticoagulation (INR 2-3) over aspirin and placebo. Despite several more recent trials with ximelagatran (e.

Cerebral venous sinus thrombosis (CVST) is a rare but potentially serious disorder in children. There is no literature on the long-term neuropsychological and emotional sequelae and implications for quality of life. We studied 17 children who had CVST after the neonatal period, aged between 1 month and 16 years at the time of CVST (mean age at CVST was 6 years, median 4 years 8 months).

Little is known about long-term physical sequelae, cognitive functioning, and quality of life of children who have had a haemorrhagic stroke. Fifty-six patients (29 females, 27 males) under 16 years of age at time of the bleeding were studied. Mean age at time of bleeding was 7.
