Intellectual Structure of Business Analytics in Information Systems

Business Analytics is arguably the most dominant topic of discussion among both academics and practitioners. As organizations scramble to derive insights from rapidly growing data, we see an exponential growth in the number of articles related to Business Analytics. The purpose of this article is to examine the conceptual foundations of the field of analytics based on an analysis of articles that have appeared in the IS senior scholars’ basket of eight journals during the last 25 years (1992 - 2016). Using a combination of citation analysis and text mining, our study: (a) reveals the disciplines that influence Business Analytics research in information systems; and (b) explicates dominant themes latent in the corpus. Concepts related to Predictive Analytics, Business Intelligence, the Web, IT Management, Firm Performance and Decision Support were found to be at the heart of analytics research conducted by IS scholars in the basket of eight journals

Mobile Clinical Decision Support Systems – A Systematic Review

In this review article, we provide a descriptive analysis of the current state of mobile decision support systems in the healthcare domain based on studies published in the following databases: Business Source Complete, CINAHL, Cochrane library, MEDLINE, PsycINFO, PubMed, ScienceDirect and Web of Science databases. A total of 29 studies were identified and analyzed to understand the current state of development, evaluation efforts, usability and challenges to adoption by patients and care providers. Our aim is to evaluate these systems and identify the key challenges which hinders their widespread adoption. Although, mobile based decision support systems in healthcare context have the potential to improve clinical decision making, the current state with low adoption rate and early stage of development need to be addressed for successful health outcomes

Speed Control of Permanent Magnet Synchronous Motor Drive Using an Inverter

Permanent Magnet Synchronous Motor are used in many applications that require rapid torque response and high – performance operation. New developed materials such as magnetic materials, conducting materials and insulating materials as well as several new applications have greatly contributed to the development of small and special purpose machines. Using such materials the size of the motor would considerably reduce and high performance motors can be built. Due to several new applications these motors are quite popular in a developing country such as India. The speed of a permanent magnet synchronous motor is varied by varying the frequency of an inverter. The performance of the motor is experimentally verified and the results are found to be encouraging. It is also observed that, under varying load condition, the speed of a motor remains constant at constant frequency

Assessment of the outcome of fracture intertrochanteric femur treated by trochanteric fixation nail in the elderly population

Background: Intertrochanteric fractures femur in elderly population are more commonly forbidden high morbidity. The surgical stabilization together with early rehabilitation is the main challenge. The elderly population have poor bone mass quality and also the chances of complications like nonunion or implant failure are more with conventional procedures. Stable fixation and early rehabilitation is the main aim in intertrochanteric fractures. The aim is to assess the functional outcome of intertrochanteric fractures femur managed by trochanteric fixation nail (TFN) in the elderly population.Methods: The study includes 40 patients, 30 male and 10 female, with fracture intertrochanteric femur treated with TFN from September 2018 to May 2019 at Yashoda Superspeciality Hospital, Nehrunagar, Ghaziabad. The patients were evaluated at 4, 8, 12 weeks postoperatively and assessed by the Modified Harris hip score. Classification used is AO classification.Results: The mean age of patients was 64 years. The mean duration of surgery was 48±10 min. The Harris hip score was 96.90±4.60, which is better than scores from other implants used for intertrochanteric fractures femur.Conclusions: In this study, we conclude that TFN is a good choice in managing the intertrochanteric fractures, having higher bone union rate and less union time. The period of immobilization is decreased, early weight bearing and less complications

A rare case of asymptomatic axial rotation of the gravid term uterus by 180 degrees

Some degree rotation of the gravid uterus in pregnancy is not an abnormal finding.However, extreme uterine torsion of 180 degrees around its cervical junction is a relatively rare event in obstetrics. Most women undergoing atorsion present with symptoms. Here, we report a rare case of asymptomatic uterine torsion detected at laparotomy for an emergency cesarean sectiondue to transverse lie in labor. As derotation of the gravid term uterus was not possible, a transverse incision in the lower posterior uterine segment was given. The clinical challenge of uterine torsion lies in its non-specific clinical course and rarity of this condition makes the preoperative diagnosis difficult

Outcomes of Pediatric Supracondylar Fractures of Humerus Treated by Posterior Triceps Splitting Approach

Introduction: Close reductions and percutaneous pinning is the gold standard treatment for supracondylar fracture  of humerus. Open reduction and internal fixation is indicated in patients with unacceptable closed reduction, neurovascular compromise, and open fractures. Open reduction can be performed through various approaches. Every approach has their advantages and limitations. The aim of this study was  to assess the functional outcome of pediatric supracondylar fracture of humerus treated by posterior triceps splitting approach. Methods: This was a prospective evaluation of 20 consecutive patients with displaced pediatric supracondylar humeral fractures operated by triceps spitting posterior approach in our institution for two years. At initial presentation, 19 cases were Gartland III  and one was flexion variant of injury. Complications such as reduction loss, pin migration, infection, osteonecrosis of any part of the elbow, bone healing, and functional results were evaluated. Flynn criteria were used to evaluate the final results. Results: Twenty patients underwent open reduction and internal fixation by triceps splitting approach. Thirteen patients were male and seven were female with M:F ratio of 1.86:1. The mean age was 6.8 yr (SD=2.74, range 2-14). All the fractures united by six weeks; mean time for union was 4.5 wk (SD=0.94). All patients were assessed at six months using Flynn clinical and radiological criteria. Results were satisfactory in all patients. Conclusion: Posterior triceps splitting approach is simple, safe and has good functional and radiological outcome. We recommend this approach  for open reduction and internal fixation in pediatric supracondylar fracture

Simultaneous Ipsilateral Pediatric Fractures of the Elbow and Forearm Attending a Tertiary Care Hospital

Introduction: Ipsilateral supracondylar humerus and forearm fractures in the pediatric population are an uncommon injury associated with high-energy trauma. The incidence varies between 3% and 13%. Our aim was to conduct a descriptive analysis on seventeen cases of children with floating elbow injuries who attended our institution and to review the literature relating to this topic. Methods: Between April 2013 to March 2016, data were obtained through the medical records. Children who had completely displaced supracondylar fractures of the humerus associated with ipsilateral forearm fracture were reviewed. All patients underwent operative reduction and percutaneous K-wire stabilization. At mean follow up of 12.9 months, all patients were assessed clinically and radiologically. The following variables were used: age, gender, side, mechanism, type of fracture, classification, treatment and complications. Results: Seventeen pediatric 'floating elbow' cases that had operative management were identified. Twelve (70.5%%) were male and five (29.4%) female. The mean age was 9.5 (SD = 2.1) years, ranging from six to 14 years. The left side was predominantly affected (70.5%). The commonest injury mechanism was fall from a height (76.47%). All the supracondylar fractures were Gartland type III. Majority of forearm fractures (76.4%) were at distal meta diaphyseal region. Distal radius physeal fractures were diagnosed in three patients. Open fractures occurred in three cases (17.6%). All supracondylar fractures were reduced and fixed using K-wires. There was one radial nerve, and three median nerve injury. Five patients had pin tract related complications. Fifteen (88.2%) patients had good to excellent, two had fair in terms of modified Flynn criteria in last month follow up. All patients went on to radiographic union without secondary procedures. Conclusion: This, uncommon injury in most cases, results from high-energy trauma. Early surgical treatment for both fractures is required in the form simultaneous closed reduction of the displaced forearm fracture followed by supracondylar fixation with K-wires. This provides not only stable fixation but also allows close observation for early sign and symptom of development of compartment syndrome

Outcome of Inferior Patellar Pole Avulsion Fractures

Introduction: The optimal treatment for inferior pole patella avulsion fractures has still been a topic of debate. The options include (a) internal fixation of the pole fragment and (b) resection of the avulsed fragment and repair of the patellar ligament to the patella. We present the comparative outcomes for patients with displaced inferior pole patella treated by resection and transosseous Ethibond® Krackow suture repair of patellar ligament with open reduction and internal fixation with modified tension band wiring and circumferential wiring. Methods: During a three year period between August 2013 and September 2016, twenty consecutive patients with distal pole fractures of the patella were prospectively enrolled in this study. These patients were divided into two groups. Group-T patients were treated with open reduction and internal fixation with modified tension band wire and  group-R patients by resection of the avulsed fragment and reattachment of the patellar ligament to the patella with #5 Ethibond®. Data entry and analysis was done by using SPSS version 20. Anatomical and functional outcome were compared. Results: Consecutive 20 patients were treated either with resection lower patellar pole (n=10) or with open reduction internal fixation with tension band wiring (n=10). Demographics were matched in two groups. Group-T required a longer hospital stay (U=13.5, p=0.005). Complications were seen more often in Goup-T compared to Group-R (p=0.005). Group-R had better scores (Bostman score U=6, p=0.001; SFMA U=7.5, p=0.001) and range of movement (p<0.05). Conclusion: Resection of the avulsed fragment and reattachment of the patellar ligament to the patella had better outcome according to the Bostman and SFMA dysfunction score, shorter hospital stay, and less complications as compared to open reduction and internal fixation with tension band wire and circumferential wiring
