1ABCD^(2) risk score does not predict the presence of cerebral microemboli in patients with hyper-acute symptomatic critical carotid artery stenosis显示文摘Introduction:ABCD^(2) risk score and cerebral microemboli detected by transcranial Doppler(TCD)have been separately shown to the predict risk of recurrent acute stroke.We studied whether ABCD2 risk score predicts cerebral microemboli in patients with hyper-acute symptomatic carotid artery stenosis.Participants and methods:We studied 206 patients presenting within 2 weeks of transient ischaemic attack or minor stroke and found to have critical carotid artery stenosis(≥50% ).86 patients(age 70±1(SEM:years),58 men,83 Caucasian)had evidence of microemboli;72(84% )of these underwent carotid endarterectomy(CEA).120 patients(age 72±1 years,91 men,113 Caucasian)did not have microemboli detected;102(85% )of these underwent CEA.Data were analysed using X2 and Mann–Whitney U tests and receiver operating characteristic(ROC)curves.Results:140/206(68% :95% CI 61.63 to 74.37)patients with hyper-acute symptomatic critical carotid stenosis had an ABCD2 risk score≥4.There was no significant difference in the NICE red flag criterion for early assessment(ABCD^(2) risk score≥4)for patients with cerebral microemboli versus those without microemboli(59/86 vs 81/120 patients:OR 1.05 ABCD2 risk score≥4(95% CI 0.58 to 1.90,p=0.867)).The ABCD2 risk score was<4 in 27 of 86(31% :95% CI 21 to 41)embolising patients and in 39 of 120(31% :95% CI 23 to 39)without cerebral microemboli.After adjusting for pre-neurological event antiplatelet treatment(APT),area under the curve(AUC)of ROC for ABCD2 risk score showed no prediction of cerebral microemboli(no pre-event APT,n=57:AUC 0.45(95% CI 0.29 to 0.60,p=0.531);preevent APT,n=147:AUC 0.51(95% CI 0.42 to 0.60,p=0.804)).Conclusions:The ABCD2 score did not predict the presence of cerebral microemboli or carotid disease in over one-quarter of patients with symptomatic critical carotid artery stenosis.On the basis of NICE guidelines(refer early if ABCD2≥4),assessment of high stroke risk based on ABCD2 scoring may lead to inappropriate delay in urgent treatment in many patients.Mahmud Saedon Charles E Hutchinson Christopher H E Imray Donald R J Singer 2017Stroke & Vascular Neurology2017,2,2:6

3Combination drug regimens for metastatic clear cell renal cell carcinoma显示文摘Renal cell carcinomas(RCC)make up about 90%of kidney cancers,of which 80%are of the clear cell subtype.About 20%of patients are already metastatic at the time of diagnosis.Initial treatment is often cytoreductive nephrectomy,but systemic therapy is required for advanced RCC.Single agent targeted therapies are moderately toxic and only somewhat effective,leading to development of immunotherapies and combination therapies.This review identifies limitations of monotherapies for metastatic renal cell carcinoma,discusses recent advances in combination therapies,and highlights therapeutic options under development.The goal behind combining various modalities of systemic therapy is to potentiate a synergistic antitumor effect.However,combining targeted therapies may cause increased toxicity.The initial attempts to create therapeutic combinations based on inhibition of the vascular endothelial growth factor or mammalian target of rapamycin pathways were largely unsuccessful in achieving a profile of increased synergy without increased toxicity.To date,five combination therapies have been approved by the U.S.Food and Drug Administration,with the most recently approved therapies being a combination of checkpoint inhibition plus targeted therapy.Several other combination therapies are under development,including some in the phase 3 stage.The new wave of combination therapies for metastatic RCC has the potential to increase response rates and improve survival outcomes while maintaining tolerable side effect profiles.Viraj V Khetani Daniella E Portal Mansi R Shah Tina Mayer Eric A Singer 2020World Journal of Clinical Oncology2020,11,8:2
