Prevalence of dementia among Indigenous populations of countries with a very high Human Development Index: a systematic review.

Dementia is a health priority for Indigenous peoples. Here, we reviewed studies on the prevalence of dementia or cognitive impairment among Indigenous populations from countries with a very high Human Development Index (≥0·8). Quality was assessed using the Joanna Briggs Institute risk-of-bias tool and CONSolIDated critERia for strengthening the reporting of health research involving Indigenous peoples (CONSIDER), with oversight provided by an Indigenous Advisory Board.

Atrial fibrillation and anticoagulation in patients hospitalised for stroke in the REGIONS Care Study.

Aim: To describe atrial fibrillation (AF) patient characteristics and anticoagulation patterns in stroke patients in Aotearoa.

Methods: Reducing Ethnic and Geographic Inequities to Optimise New Zealand Stroke (REGIONS) Care study is a prospective, nation-wide observational study of consecutive adult stroke patients admitted to hospital between 1 May and 31 October 2018. AF and anticoagulation prescribing, intracerebral haemorrhage (ICH) and differences by Māori ethnicity and hospital location are described.

Predicting Motor Outcomes Using Atlas-Based Voxel Features of Post-Stroke Neuroimaging: A Scoping Review.

Background: Atlas-based voxel features have the potential to aid motor outcome prognostication after stroke, but are seldom used in clinically feasible prediction models. This could be because neuroimaging feature development is a non-standardized, complex, multistep process. This is a barrier to entry for researchers and poses issues for reproducibility and validation in a field of research where sample sizes are typically small.

Clinical outcomes of delayed mechanical thrombectomy: Descriptive analysis and development of a screening tool.

Background And Purpose: Limited data guide the selection of patients with large vessel occlusion ischaemic stroke who may benefit from referral to a distant tertiary centre for mechanical thrombectomy (MT). We aimed to characterize this population, describe clinical outcomes and develop a screening system to identify patients most likely to benfit from delayed mechanical thrombectomy (MT).

Methods: We undertook a retrospective cohort analysis enrolling patients transferred from regional sites to one of two MT comprehensive stroke units with a time from non-contrast computed tomography (NCCT) of the brain to reperfusion of 4 h or more.

Reducing Ethnic and Geographic Inequities to Optimise New Zealand Stroke Care (REGIONS Care): Protocol for a Nationwide Observational Study.

Background: Stroke systems of care differ between larger urban and smaller rural settings and it is unclear to what extent this may impact on patient outcomes. Ethnicity influences stroke risk factors and care delivery as well as patient outcomes in nonstroke settings. Little is known about the impact of ethnicity on poststroke care, especially in Māori and Pacific populations.

Community Knowledge and Awareness of Stroke in New Zealand.

Introduction: Community knowledge and stroke awareness is crucial for primary prevention of stroke and timely access to stroke treatments including acute reperfusion therapies. We conducted a national telephone survey to quantify the level of community stroke awareness.

Methods: A random sample of 400 adults in New Zealand (NZ), stratified by the 4 main ethnic groups, was surveyed.

Stroke thrombolysis in New Zealand: data from the first 6 months of the New Zealand Thrombolysis Register.

The New Zealand National Stroke Network introduced a National Stroke Thrombolysis Register on the first of January 2015 to assist with quality assurance and continuous service improvement. In the first 6 months, there were 179 [75 women, mean (SD) age 69.9 (14) years] treated with stroke thrombolysis out of a total of 2,796 ischaemic stroke patients, giving a national thrombolysis rate of 6.

Endovascular clot retrieval for acute ischaemic stroke: the Auckland City Hospital experience.

Aims: In acute ischaemic stroke, endovascular therapy with the Solitaire FR stent retriever has been shown to double recanalisation rates and the numbers of patients who recover to be functionally independent, when compared to standard therapy. We present the Auckland City Hospital experience of clot retrieval.

Methods: Previously independent ischaemic stroke patients with contraindications to, or no response following, i.

Stroke awareness and knowledge in an urban New Zealand population.

Background: Stroke is the third most common cause of death and a major cause of chronic disability in New Zealand. Linked to risk factors that develop across the life-course, stroke is considered to be largely preventable. This study assessed the awareness of stroke risk, symptoms, detection, and prevention behaviors in an urban New Zealand population.

Bilateral priming accelerates recovery of upper limb function after stroke: a randomized controlled trial.

Background And Purpose: The ability to live independently after stroke depends on the recovery of upper limb function. We hypothesized that bilateral priming with active-passive movements before upper limb physiotherapy would promote rebalancing of corticomotor excitability and would accelerate upper limb recovery at the subacute stage.

Methods: A single-center randomized controlled trial of bilateral priming was conducted with 57 patients randomized at the subacute stage after first-ever ischemic stroke.

Cannabis, ischemic stroke, and transient ischemic attack: a case-control study.

Background And Purpose: There is a temporal relationship between cannabis use and stroke in case series and population-based studies.

Methods: Consecutive stroke patients, aged 18 to 55 years, who had urine screens for cannabis were compared with a cohort of control patients admitted to hospital without cardiovascular or neurological diagnoses.

Results: One hundred sixty of 218 (73%) ischemic stroke/transient ischemic attack patients had urine drug screens (100 men; mean [SD] age, 44.

High-dielectric polymer composite materials from a series of mixed-metal phenylphosphonates, ATi(C6H5PO3)3 for dielectric energy storage.

We report the preparation of new polymer composite dielectric materials for energy storage applications. New layered 1:1 mixed A+2/Ti4+ metal phenylphosphonates, ATi(O3PC6H5)3, A=Mg, Ca, Sr, Ba, and Pb, have been prepared via a melt route, in which mixed metal oxides, ATiO3, were reacted with molten phenyl phosphonic acid. The mixed-metal phosphonates were combined with polystyrene (PS) via a solution route and cast as thin films for dielectric permittivity measurements.

On-road vehicle particulate matter and gaseous emission distributions in Las Vegas, Nevada, compared with other areas.

During the spring and summer of 2000, 2001, and 2002, gaseous and particulate matter (PM) fuel-based emission factors for approximately 150,000 low-tailpipe, individual vehicles in the Las Vegas, NV, area were measured via on-road remote sensing. For the gaseous pollutants (carbon monoxide, hydrocarbons, and nitrogen oxide), a commercial vehicle emissions remote sensing system (VERSS) was used. The PM emissions were determined using a Lidar-based VERSS.

Remote sensing of PM, NO, CO and HC emission factors for on-road gasoline and diesel engine vehicles in Las Vegas, NV.

A novel light detection and ranging-based remote sensing system was assembled and used to measure mass particulate matter (PM) emissions per unit of fuel burned from in-use on-road vehicles. A commercially available remote sensing system was concurrently used to measure emissions of carbon monoxide (CO), nitrogen oxide (NO) and hydrocarbons (HC). The two systems were used to measure 61,207 gasoline and 1180 diesel powered vehicle emissions in Las Vegas, NV from 4/4/2000 to 5/16/2002.

On-road measurement of automotive particle emissions by ultraviolet lidar and transmissometer: instrument.

A novel vehicle emissions remote sensing system (VERSS) for the on-road measurement of fuel-based particulate matter (PM) emission factors is described. This system utilizes two complementary PM channels using an ultraviolet Lidar and transmissometer for the measurement of PM mass column content behind a passing vehicle. Ratioing the PM mass column content with the carbon mass column content, simultaneously measured with infrared absorption, yields the fuel-based PM mass emission factor.
