It is well established that ethnocultural groups of migrants are associated with a differential risk of communicable disease, including measles, tuberculosis and hepatitis B. Global public health agencies¹ are now focusing on improving the collection of ethnocultural data to better define communicable disease risk in migrant populations to support community-level disease prevention and control.

Intravenous thrombolysis is an effective treatment for acute ischaemic stroke. However, vascular recanalization rates remain poor especially in the setting of large artery occlusion. On the other hand, endovascular intra-arterial therapy addresses this issue with superior recanalization rates compared with intravenous thrombolysis. Although previous randomized controlled studies of intra-arterial therapy failed to demonstrate superiority, the failings may be attributed to a combination of inferior intra-arterial devices and suboptimal selection criteria. The recent results of several randomized controlled trials have demonstrated significantly improved outcomes, underpinning the advantage of newer intra-arterial devices and superior recanalization rates, leading to renewed interest in establishing intra-arterial therapy as the gold standard for acute ischaemic stroke. The aim of this review is to outline the history and development of different intra-arterial devices and future directions in research.

INTRODUCTIONTo assess the association between sensory and cognitive function, and the potential influence of visual function on cognitive function assessment, in a sample of clients accessing aged care services.

MATERIALS AND METHODSWe recruited 260 non-institutionalised, frail, older individuals who sought aged care services. Visual acuity was assessed using a LogMAR chart and hearing function was measured using a portable pure-tone air conduction audiometer. Visual impairment was defined as visual acuity (VA) <6/12 (<39 letters read correctly in the better eye), moderate-to-severe hearing impairment as hearing thresholds >40 decibels (better ear) and cognitive impairment as Mini-Mental State Examination (MMSE) score <24.

RESULTSVision and hearing assessments were randomly performed in 168 and 164 aged care clients, respectively. Visual acuity correlated weakly with MMSE scores, either including (r = 0.27, P <0.001) or excluding (r = 0.21, P = 0.006) vision-related MMSE items. After partialling out the effect of age, the association remained (r = 0.23, P = 0.013 including, or r = 0.18, P = 0.044 excluding vision-related items). No correlation was found between MMSE scores and hearing thresholds (r = -0.07, P = 0.375). After adjusting for age, sex and stroke, mean MMSE scores were lower in persons with visual impairment than those with normal vision (25.2 + 0.5 versus 26.8 + 0.4 including, or 18.2 + 0.5 versus 19.2 + 0.3 excluding vision-related items), but were similar between subjects with none or mild and those with moderate-to-severe hearing loss (26.3 + 0.4 versus 26.0 + 0.4).

CONCLUSIONSIn this study sample, visual and cognitive functions were modestly associated, after excluding the influence of visual impairment on the MMSE assessment and adjusting for age. Hearing thresholds were not found to be associated with cognitive function.

BACKGROUND AND PURPOSE: Leptomeningeal collaterals maintain arterial perfusion in acute arterial occlusion but may fluctuate subject to arterial blood pressure (ABP). We aim to investigate the relationship between ABP and collaterals as assessed by computer tomography (CT) perfusion in acute ischemic stroke. METHODS: We retrospectively analyzed acute anterior circulation ischemic stroke patients with CT perfusion from 2009 to 2014. Collateral status using relative filling time delay (rFTD) determined by time delay of collateral-derived contrast opacification within the Sylvian fissure, from 0 seconds to unlimited count. The data were analyzed by zero-inflated negative binomial regression model including an appropriate interaction examining in the model in terms of occlusion location and onset-to-CT time (OCT). RESULTS: Two hundred and seventy patients were included. We found that increment of 10 mm Hg in BP, the odds that a patient would have rFTD equal to 0 seconds increased by 27.9% in systolic BP (SBP) (p=0.001), by 73.9% in diastolic BP (DBP) (p<0.001) and by 68.5% in mean BP (MBP) (p<0.001). For patients with rFTD not necessarily equal to 0 seconds, every 10 mm Hg increase in BP, there was a 7% decrease in expected count of seconds for rFTD in SBP (p=0.002), 10% decrease for rFTD in DBP and 11% decrease for rFTD in MBP. The arterial occlusion location and OCT showed no significant interaction in the BP-rFTD relationship (p>0.05). CONCLUSIONS: In acute ischemic stroke, higher ABP is possibly associated with improved leptomeningeal collaterals as identified by decreased rFTD.

Background: and Purpose The benefit regarding co-treatment with intravenous (IV) thrombolysis before mechanical thrombectomy in acute ischemic stroke with large vessel occlusion remains unclear. To test the hypothesis that clinical outcome of ischemic stroke patients with intracranial internal carotid artery, middle cerebral artery or basilar artery occlusion treated with direct endovascular thrombectomy within 4.5 hours will be non-inferior compared with that of standard bridging IV thrombolysis followed by endovascular thrombectomy. Methods: To randomize 780 patients 1:1 to direct thrombectomy or bridging IV thrombolysis with thrombectomy. An international-multicenter prospective randomized open label blinded endpoint trial (PROBE) (ClincalTrials.gov identifier: NCT03494920). Results: Primary endpoint is functional independence defined as modified Rankin Scale (mRS) 0–2 or return to baseline at 90 days. Secondary end points include ordinal mRS analysis, good angiographic reperfusion (modified Thrombolysis in Cerebral Infarction score [mTICI] 2b–3), safety endpoints include symptomatic intracerebral hemorrhage and death. Conclusions DIRECT-SAFE will provide unique information regarding the impact of direct thrombectomy in patients with large vessel occlusion, including patients with basilar artery occlusion, with comparison across different ethnic groups.

Objective: To evaluate financial toxicity and assess its risk factors among patients with gynecologic cancers. Methods: This is a cross sectional study that included 2 survey tools, as well as patient demographics, disease characteristics, and treatment regimen. Financial toxicity is measured by validated Comprehensive Score for Financial Toxicity (COST) tool. Participants were also asked to complete a 55-question-survey on attitudes and perspectives surrounding cost of care. Descriptive statistics was used to report patient demographics. Spearman's rank correlation was calculated to assess the relation between financial toxicity and patient/disease related variables. Graphpad Prism Software Version 8.0 was used for analyses. Results: A total of 50 patients with various gynecologic malignancies were enrolled. Median COST score was 20.5 (range, 1–33). Sixty-five percent of the patients reported being in debt due to their cancer care and 4% filed bankruptcy. Correlation analysis showed that COST score was correlated with age (r=−0.3, p=0.028), malignancy type (r=0.3, p=0.039) and income (r=0.3, p=0.047). Ovarian cancer patients had significantly less financial toxicity (median COST score=23) when compared to patients with other gynecologic malignancies (median COST score=17, p=0.043). When scores were dichotomized into low (score ≥22) and high toxicity (score <22), 58% (29/50) of the patients were noted to have high financial toxicity. Enrollment to a clinical trial did not significantly alleviate financial burden. Conclusion Financial toxicity is a significant burden even among highly insured gynecologic oncology patients. Age, malignancy type and income were correlated with high financial burden.
