Comparing text classifiers for sports news
AbstractThe rise of Machine Learning (ML) techniques has given life to text classification discipline and its many applications we enjoy these days such as spam filters and opinion mining which became an essential part of our daily life. Tools and techniques have shown tremendous maturity especially in the past two decades. In this paper, we revisit this field using both commodity software and hardware to show progress of both efficiency and effectiveness of a group of ML-based methods in classifying Cricket sports news articles
Peribulbar versus sub-Tenon block in cardiac patients undergoing cataract surgery during warfarin therapy
AbstractObjectiveTo compare sub-Tenon’s block with peribulbar block in patients on oral warfarin therapy undergoing cataract surgery.Materials and methodsWe studied 100 patients on warfarin undergoing cataract surgery; randomly allocated into one of two groups; sub-Tenon’s group (group S, n=50), and peribulbar group (group P, n=50). In group (S), sub-Tenon’s injection of 3–5ml of anesthetic agent was done using a 25mm sub-Tenon’s cannula. In group (P), the peribulbar block with 3–4ml of 2% lidocaine–hyaluronidase (10IU/ml) and 0.5% bupivacaine was done. Pain and akinesia and postoperative complications were assessed.ResultsSub-Tenon group showed significantly higher frequency of hemorrhage compared to peribulbar group (30% versus 8%, p=0.041), mainly of grade I. The two groups had comparable frequency of subconjunctival hemorrhage (p=1.000). No patients experienced sight-threatening hemorrhagic complications. Pain was significantly lower in the sub-Tenon group. Akinesia was significantly better (p=0.025) 2min after injection and comparable from 4 to 10min after injection in the peribulbar group. The majority of patients in the two groups reported satisfaction (p=0.372). The surgeon expressed higher satisfaction with peribulbar block (94%) compared to sub-Tenon’s block (81%) (p=0.064).ConclusionPeribulbar and sub-Tenon techniques were relatively safe in patients on anticoagulants during cataract operation. We recommend peribulbar technique owing to significantly less bleeding and more satisfactory akinesia response and hence surgeon comfort
