Automatic Migration of Data to NoSQL Databases Using Service Oriented Architecture

For the past few years there has been an exponential rise in the use of databases which are not true relational databases. There is no correct definition of such databases but can only be described with a set of common characteristics such absence of a fixed schema, inherent scalability features, high performance, data etc. These databases have come to be known as NoSQL databases. Various companies are seeing the advantages of NoSQL and want to migrate to these databases. But they find it difficult to migrate their data as a lot of study and analysis is required. Each type of database have their own terminology and query language. We propose a novel automated migration model which utilizes the power of service oriented architecture to help these companies easily migrate to NoSQL databases of their choice. We utilize web services which encapsulates few of the most popular NoSQL databases such as MongoDB, Neo4j, Cassandra etc. so that inner details of these databases are hidden yet providing efficient migration of data with little or no knowledge of the inner working of these databases. As proof of concept relational data was migrated successfully from Apache Derby database to MongoDB, Cassandra, Neo4j and DynamoDB, each vendor representing a different type of NoSQL database

An Extensive Volar Forearm Laceration – The Spaghetti Wrist: A Systematic Review

PURPOSE: ‘Spaghetti wrist’ is an extensive laceration that involves multiple structures in the volar wrist, including tendons, nerves and arteries. This injury is frequently encountered in trauma units, but despite its complex nature, management is often handled by junior surgeons. Furthermore, the guidance on how to approach these injuries is limited, with a relatively poor evidence base on management and outcomes. METHODS: In this article, we perform a systematic review of the literature on the management and outcomes of the spaghetti wrist injury. Patient demographics, definitions of spaghetti wrist, mechanism of injury, operative and rehabilitative techniques and surgical outcomes are discussed. RESULTS: Results from this study show significant physical, functional, psychological and financial impacts of spaghetti wrist injuries. Operative technique appears relatively consistent; even though reporting of injuries and outcomes was heterogeneous, no current classification system is in common usage. CONCLUSIONS: An increased focus on the standardisation of assessment, management and rehabilitation and on overcoming the obstacles to care will serve as a guidance to the operative and post-operative management of the spaghetti wrist injury. The use of a single definition and classification system has been proposed to standardise outcome measures and improve inter-observer reliability

A Survey of Empirical Results on Program Slicing

International audienceBACKGROUND:Patients with peripheral artery disease have an increased risk of cardiovascular morbidity and mortality. Antiplatelet agents are widely used to reduce these complications.METHODS:This was a multicentre, double-blind, randomised placebo-controlled trial for which patients were recruited at 602 hospitals, clinics, or community practices from 33 countries across six continents. Eligible patients had a history of peripheral artery disease of the lower extremities (previous peripheral bypass surgery or angioplasty, limb or foot amputation, intermittent claudication with objective evidence of peripheral artery disease), of the carotid arteries (previous carotid artery revascularisation or asymptomatic carotid artery stenosis of at least 50%), or coronary artery disease with an ankle-brachial index of less than 0·90. After a 30-day run-in period, patients were randomly assigned (1:1:1) to receive oral rivaroxaban (2·5 mg twice a day) plus aspirin (100 mg once a day), rivaroxaban twice a day (5 mg with aspirin placebo once a day), or to aspirin once a day (100 mg and rivaroxaban placebo twice a day). Randomisation was computer generated. Each treatment group was double dummy, and the patient, investigators, and central study staff were masked to treatment allocation. The primary outcome was cardiovascular death, myocardial infarction or stroke; the primary peripheral artery disease outcome was major adverse limb events including major amputation. This trial is registered with ClinicalTrials.gov, number NCT01776424, and is closed to new participants.FINDINGS:Between March 12, 2013, and May 10, 2016, we enrolled 7470 patients with peripheral artery disease from 558 centres. The combination of rivaroxaban plus aspirin compared with aspirin alone reduced the composite endpoint of cardiovascular death, myocardial infarction, or stroke (126 [5%] of 2492 vs 174 [7%] of 2504; hazard ratio [HR] 0·72, 95% CI 0·57-0·90, p=0·0047), and major adverse limb events including major amputation (32 [1%] vs 60 [2%]; HR 0·54 95% CI 0·35-0·82, p=0·0037). Rivaroxaban 5 mg twice a day compared with aspirin alone did not significantly reduce the composite endpoint (149 [6%] of 2474 vs 174 [7%] of 2504; HR 0·86, 95% CI 0·69-1·08, p=0·19), but reduced major adverse limb events including major amputation (40 [2%] vs 60 [2%]; HR 0·67, 95% CI 0·45-1·00, p=0·05). The median duration of treatment was 21 months. The use of the rivaroxaban plus aspirin combination increased major bleeding compared with the aspirin alone group (77 [3%] of 2492 vs 48 [2%] of 2504; HR 1·61, 95% CI 1·12-2·31, p=0·0089), which was mainly gastrointestinal. Similarly, major bleeding occurred in 79 (3%) of 2474 patients with rivaroxaban 5 mg, and in 48 (2%) of 2504 in the aspirin alone group (HR 1·68, 95% CI 1·17-2·40; p=0·0043).INTERPRETATION:Low-dose rivaroxaban taken twice a day plus aspirin once a day reduced major adverse cardiovascular and limb events when compared with aspirin alone. Although major bleeding was increased, fatal or critical organ bleeding was not. This combination therapy represents an important advance in the management of patients with peripheral artery disease. Rivaroxaban alone did not significantly reduce major adverse cardiovascular events compared with asprin alone, but reduced major adverse limb events and increased major bleeding
