1Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
2Haemoxygenase modulates cytokine induced neutrophil chemoattractant in hepatic ischemia reperfusion injury显示文摘AIM To investigate the hepatic microcirculatory changes due to Haemoxygenase(HO),effect of HO inhibition on remote ischemic preconditioning(RIPC) and modulation of CINC.METHODS Eight groups of animals were studied- Sham,ischemia reperfusion injury(IRI) the animals were subjected to 45 min of hepatic ischemia followed by three hours of reperfusion,RIPC(remote ischemic preconditioning) + IRI group,remote ischemic preconditioning in sham(RIPC + Sham),PDTC + IR(Pyridodithiocarbamate,HO donor),Zn PP + RIPC + IRI(Zinc protoporphyrin prior to preconditioning),IR-24(45 min of ischemia followed by 24 h of reperfusion),RIPC+IR-24(preconditioning prior to. After 3 and 24 h of reperfusion the animals were killed by exsanguination and samples were taken. RESULTS Velocity of flow(160.83 ± 12.24 μm/s),sinusoidal flow(8.42 ± 1.19) and sinusoidal perfusion index(42.12 ± 7.28) in hepatic IR were lower(P < 0.05) in comparison to RIPC and PDTC(HO inducer). RIPC increased velocity of flow(328.04 ± 19.13 μm/s),sinusoidal flow(17.75 ± 2.59) and the sinusoidal perfusion index(67.28 ± 1.82)(P < 0.05). PDTC(HO induction) reproduced the effects of RIPC in hepatic IR. PDTC restored RBC velocity(300.88 ± 22.109 μm/s),sinusoidal flow(17.66 ± 3.71) and sinusoidal perfusion(82.33 ± 3.5) to near sham levels. Zn PP(HO inhibition) reduced velocity of flow of RBC in the RIPC group(170.74 ± 13.43 μm/s and sinusoidal flow in the RIPC group(9.46 ± 1.34). Zn PP in RIPC(60.29 ± 1.82) showed a fall in perfusion only at 180 min of reperfusion. Neutrophil adhesion in IR injury is seen in both postsinusoidal venules(769.05 ± 87.48) and sinusoids(97.4 ± 7.49). Neutrophil adhesion in RIPC + IR injury is reduced in both postsinusoidal venules(219.66 ± 93.79) and sinusoids(25.69 ± 9.08)(P < 0.05). PDTC reduced neutrophil adhesion in both postsinusoidal venules(89.58 ± 58.32) and sinusoids(17.98 ± 11.01)(P < 0.05) reproducing the effects of RIPC. Zn PP(HO inhibition) increased venular(589.04 ± 144.36) and sinusoidal neutrophil adhesion in preconditioned animals(121.39 ± 30.65)(P < 0.05). IR after 24 h of reperfusion increased venular and sinusoidal neutrophil adhesion in comparison to the early phase and was significantly reduced by RIPC. Hepatocellular cell death in IRI(80.83 ± 13.03),RIPC + IR(17.35 ± 2.47),and PTDC+IR(11.66 ± 1.17) Zn PP + RIPC + IR(41.33 ± 3.07) reduced hepatocellular death. Zn PP significantly increased hepatocellular death(P < 0.05 PTDC/RIPC vs Zn PP and IR). The CINC cytokine levels in sham(101.32 ± 6.42). RIPC + sham(412.18 ± 65.24) as compared to sham(P < 0.05). Hepatic IR(644.08 ± 181.24)(P < 0.05). RIPC CINC-1 levels in the early phase(401.62 ± 78.56). And PDTC(HO inducer) CINC-1 levels in hepatic IR(413.36 ± 63.06) were significantly lower. HO inhibition in preconditioned animals with Zinc protoporphyrin increased serum CINC levels(521.81 ± 74.9)(P < 0.05). The serum CINC levels were high in the late phase of hepatic IR(15306 ± 1222.04). RIPC reduced CINC levels in the late phase of IR(467.46 ± 26.06),P < 0.05.CONCLUSION RIPC protects hepatic microcirculation by induction of HO and modulation of CINC in hepatic IR.Niteen Tapuria Sameer Junnarkar Mahmoud Abu-amara Barry Fuller Alexander M Seifalian Brian R Davidson 2016World Journal of Gastroenterology2016,22,33:3

6Acute ischaemic stroke interventions: large vessel occlusion and beyond显示文摘Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy.Large vessel occlusion(LVO)accounts for up to 38%of acute ischaemic stroke and comes with devastating outcomes for patients,families and society in the pre-intervention era.A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke;this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits.This review article will present a comprehensive overview of LVO management,techniques and devices used,and the future of stroke therapy.In addition,we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.Ahmad Sweid Batoul Hammoud Sunidhi Ramesh Daniella Wong Tyler D Alexander Joshua Harrison Weinberg Maureen Deprince Jaime Dougherty Dimitri Jean-Mickael Maamari Stavropoula Tjoumakaris Hekmat Zarzour Michael R Gooch Nabeel Herial Victor Romo David M Hasan Robert H Rosenwasser Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:2
