A Modified Hierarchical Agglomerative Approach for Efficient Document Clustering System

In today’s world, the increasing volume of text documents has brought challenges for their effective and efficient organization. This has led to an enormous demand for efficient tools that turn data into valuable knowledge. One of the techniques that can play an important role towards the achievement of this objective is document clustering. The main function of document clustering is automatic grouping of documents so that the documents within a cluster are very similar, but dissimilar to the documents in other clusters. This research proposes a Modified Agglomerative Hierarchical Clustering (MAHC) algorithm based on hierarchical method. In many traditional systems, the number of term frequency is considered to create data representation matrix. However, a modified algorithm creates data representation matrix based only on occurrence of items, not on frequency of items. The proposed algorithm can increase the quality of clustering because it can merge the related or similar documents into the same cluster efficiently. Moreover, the proposed algorithm can reduce the processing time than the existing methods. In this paper, the performance of clustering between the proposed and original clustering algorithm was compared and evaluated by using F-measure

Influenza A Viral Infection with Septic Shock in Pregnancy

Te infuenza virus is RNA virus and is classifed into four subtypes, infuenza A, infuenza B, infuenza C, and infuenza D. One of the subtypes of infuenza A, the H1N1 strain, also known as swine fu, is especially of high risk for development of complications in pregnant women. Te influenza A virus infection is difficult to diagnose clinically because its presenting symptoms are similar to those of the common cold but are more severe, last longer, and can be potentially life-threatening. This case also presented with common cold symptoms but her condition worsened later. Fortunately, obstetric health providers were vigilant enough to address the developing infection and its related complications. It was the cooperative effort of multidisciplinary team care which resulted in a flavourable outcome in both mother and baby

Adverse Drug Reactions in Selected Wards of the Yangon General Hospital and Yangon Specialty Hospital During the First Quarter of 2019 : An Active Pharmacovigilance Study in Myanmar

Previous studies in Europe and the USA have reported a high prevalence of adverse drug reactions (ADRs), but data on local ADRs in Myanmar are sparse. Our objective was to study ADRs in patients admitted to selected wards of Yangon General Hospital (YGH) and Yangon Specialty Hospital (YSH), Myanmar. This was a prospective observational study in three hospital wards during the first quarter of 2019. Suspected ADRs were carefully investigated in a face-to-face interview with each patient and via review of clinical records. Patients transferred to other wards or discharged were followed-up by the researchers until day 28 after admission. ADRs were divided into those that (1) led to the admission and (2) occurred during the hospital stay or after discharge (up to day 28 after admission). A total of 65 ADRs were identified, with 47 (29.4%) of 160 patients experiencing at least one ADR. Among these, 16 (24.6%) had led to hospital admission and 49 (75.4%) occurred in 31 patients during their hospital stay. Of 160 patients, 21 had taken at least one herbal remedy and six of these developed an ADR. Five ADR-drug associations (hypokalaemia with methylprednisolone, increased transaminase levels with standard antituberculosis drugs, upper gastrointestinal bleeding with nonsteroidal anti-inflammatory drugs, constipation with tramadol, and increased transaminase levels with herbal remedies) represented 18 (27.7%) of the 65 ADRs in this study. According to the Schumock and Thornton preventability scale, more than half of these ADRs (35 [53.9%]) were preventable. The present study highlights the existence of ADRs among patients attending these hospitals. The implementation of active pharmacovigilance in hospitals could be a helpful first step to improving the awareness of unwanted effects of medicines and patient safety, as well as a way to strengthen the national pharmacovigilance system in countries such as Myanmar.
