Treating stroke patients just 15 minutes earlier can save lives
Initiating stroke treatment just 15 minutes faster can save lives and prevent disability, according to a new UCLA-led study, published today inJAMA. The research also determined that busier hospitals — those that treat more than 450 people for stroke each year — have better outcomes than those that treat fewer than 400 stroke patients per year.Researchers at the  David Geffen School of Medicine at UCLA and five other institutions in the U.S. and Canada, examined data for 6,756 people who experienced ischemic strokes. The patients ’ median age was 71, and 51.2% were women.The researchers looked at stroke patients ’...

Secondary prevention treatment after acute stroke in older South Asian, Chinese and other Canadians: a retrospective data analysis.
Abstract BACKGROUND: Little is known about whether there are differences in medication use between older patients of Chinese descent, those of South Asian descent and other Canadian patients after acute ischemic or primary intracerebral hemorrhagic stroke. The aim of this population-based study was to evaluate potential ethnic differences in secondary prevention pharmacotherapy after acute stroke. METHODS: Using health administrative data, we conducted a retrospective analysis of all patients aged 66 years or more admitted to hospital with acute stroke in Ontario (1997-2011) and British Columbia (1997-2009). ...

Early predictive blood markers of hemorrhagic stroke - influence of cytoflavin therapy.
This study aimed to determine early changes in the parameters of oxidative stress and routine biochemistry blood tests in patients with HS and to assess their relationship with clinical outcome. The effects of early applied cytoflavin were also investigated. The prospective study included 151 patients with HS. 48% of patients in the standard conservative therapy was added cytoflavin antioxidant energy therapy from the first day of hospitalization. The neurological status, neuroimaging, biochemical blood tests and free radical processes were assessed on days 1, 5, 10, 20 of hospitalization. In patients with HS, an imbalance...

Efficacy and safety of minimally invasive surgery with thrombolysis in intracerebral haemorrhage evacuation (MISTIE III): a randomised, controlled, open-label, blinded endpoint phase 3 trial
This study is registered with ClinicalTrials.gov, number NCT01827046.FindingsBetween Dec 30, 2013, and Aug 15, 2017, 506 patients were randomly allocated: 255 (50%) to the MISTIE group and 251 (50%) to standard medical care. 499 patients (n=250 in the MISTIE group; n=249 in the standard medical care group) received treatment and were included in the mITT analysis set. The mITT primary adjusted efficacy analysis estimated that 45% of patients in the MISTIE group and 41% patients in the standard medical care group had achieved an mRS score of 0–3 at 365 days (adjusted risk difference 4% [95% CI −4 to 12]; p=0·33).

Management of Cerebral Vein Thrombosis in a Canadian Tertiary Hospital
Introduction: Cerebral vein thrombosis (CVT) is an uncommon cause of stroke and is more likely to affect young adults and children. Women have a three-fold increased risk compared to men, owing to gender specific factors such as oral contraceptive use (OCP), pregnancy, and hormone replacement therapies. The presenting symptoms of CVT are non-specific and include headache, seizure, focal neurological deficits, or coma as the most severe presentation. The rarity and variable symptoms of the disease leads to delayed diagnosis and implementation of treatment. With improved imaging techniques and increased awareness in recent y...

Clinical characteristics, multiorgan dysfunction and outcomes of patients with COVID-19: a prospective case series
This study provides further evidence that COVID-19 is a multisystem disease involving neurologic, cardiac and thrombotic dysfunction, without evidence of hepatic dysfunction. Patients have persistent organ dysfunction after hospital discharge, underscoring the need for research on long-term outcomes of COVID-19 survivors.PMID:35853662 | DOI:10.9778/cmajo.20210151
