Cardiac Disease Diagnosis Using K-Nearest Neighbor Algorithm: A Study on Heart Failure Clinical Records Dataset

This article introduces an approach to diagnose heart diseases utilizing the K-Nearest Neighbor algorithm and diverse correlation filters for selecting the most pertinent attributes. Results high- light that meticulous filter selection enhances survival predictions in patients with heart diseases. Employing K = 5 and correlation filter CF = 0.1, key attributes for classification were identified as anemia, high blood pressure, serum creatinine, and sex. Omitting the 'time' attribute led to information loss but was crucial to prevent biases and generalize predictions across various clinical scenarios. Utilizing these classification parameters, we designed an Android mobile application called “Heart Info System”, functioning as an artificial intelligence service. It employs the K-Nearest Neighbor algorithm with optimal parameters to evaluate the probability of survival in the progression of heart disease. The main activity of the application retrieves data from a Firebase database. While the study results show promise, the accuracy of the application may be influenced by inaccurate or incomplete input data. Nevertheless, this application has the potential to improve the early detection of heart diseases, paving the way for life-saving interventions.

Trends in teenage pregnancy in Brazil in the last 20 years (2000-2019).

The aim of this study was to evaluate the frequency of teenage pregnancy in all Brazilian regions and states in the period of 2000-2019 among two age groups, namely, 10-14 and 15-19 years old, and correlate it with the human development index. A cross-sectional study was performed by using the data from the Live Birth Info System from the National Health System's database. The percentage of live births from teenage mothers (age 10-19 years) in Brazil decreased by 37.2% (i.e., 23.4 in 2000 to 14.7% in 2019) in all regions. Amazonas and Maranhão were the only states to show increased fertility rates for teens in the age group of 10-14 years. The fertility index decreased from 80.9-48% in all states among mothers aged 15-19 years. Only the Southeast and South regions showed levels below the Brazilian average (i.e., 38.2 and 39%, respectively). The proportion of live birth showed an inversely proportional trend to the human development index score. Brazil shows a decline in the percentage of live birth among adolescent mothers and the fertility rate. Live birth is inversely proportional to the human development index score. However, the teenage pregnancy numbers are still high, with great regional inequality in the country.

Nail Patterns in Papulosquamous Disorders- An Observational Study from Southern India

Introduction: Nail changes are always a cause of physical handicap and psychological stress in this era where utmost importance is given to cosmetic appearance. Other than trauma and infections, Papulosquamous disorders are major contributor to nail changes. Thorough knowledge of their patterns will aid in early detection and treatment before irreversible damage to nails occurs. Aim: To observe the clinical patterns of nail changes in various papulosquamous disorders. Materials and Methods: This observational descriptive cross- sectional study was conducted in a tertiary care set up at Government Coimbatore Medical College, Coimbatore from June 2016 to June 2017. The study group comprised of 104 cases of various papulosquamous disorders. The type of papulosquamous disorder, presence of nail changes, their onset, duration, various patterns and associated co-morbidities were noted in detail. The observed data were entered in Microsoft Excel and data analysis was done in Epi Info system. Results: Out of the 104 cases taken for study 71 (68%) had nail changes. Majority of them were in 31-45 years age group (n=29; 41%). More of males (n=38, 54%) had nail changes than the females (n=33, 46%). Psoriasis (n=47; 66%) was the most common papulosquamous disorder with nail changes followed by lichen planus (n=9; 13%) and pityriasis rubrapilaris (n=7; 10%). Pitting of nails was the most common nail pattern (n=44; 62%), followed by subungual hyperkeratosis (n=24; 34%), thickened nail plate and longitudinal striations (both n=19; 27%). Finger nails were more affected than toe nails. Psoriasis and pityriasis rubrapilaris had 100% nail involvement. The patterns of nail changes were maximum in psoriasis and lichen planus. Beaus lines was observed in most of the papulosquamous disorders except Lichen nitidus and Lichen striatus. The time gap for onset of nail changes was longer for psoriasis (4.2 years) and shorter for pityriasis rosea (two months). In lichen striatus and lichen nitidus, nails were involved only in children. Minimal nail changes were observed in para psoriasis and pityriasis lichenoides. More number of co-morbidities like diabetes, hypertension, atopy and arthritis were seen in psoriasis. Conclusion: In the present study, it was observed that the nail changes were more common in psoriasis, lichen planus and pityriasis rubra pilaris among the papulosquamous disorders. The highly frequent nail patterns were pitting and subungual hyperkeratosis.

Efficient separation and allocation of dataset in structured and unstructured databases

An economical practicality of any distributed info system is very passionate about its correct style in terms of adopted fragmentation and allocation ways. Fragmentations of huge, international square measure performed by dividing the database horizontally, vertically or combination of each. So as to change the distributed info systems to figure expeditiously, the fragments need to be allotted across the obtainable sites in such some way that reduces communication price of knowledge. Throughout fragmentation, fragment size and fragment structure need to be thought-about. So as to extend the performance and to cut back the communication price throughout fragmentation and fragment allocation among sites over a network, a technique of agglomeration sites is planned. This cluster operation among sites is finished consistent with the communication price between sites. The sites that square measure nearer specified they need low price among them to try to the communication square measure classified mutually cluster. Conjointly the static allocation of fragments provides solely the restricted response to the changes in work. Thus dynamic ways square measure adopted for fragmentation of each structured and unstructured databases. This reduces the movement of knowledge and conjointly improves the system performance.

Ugotavljanje dehidracije pri starostnikih, ki so bili obravnavani na nujni medicinski pomoči: akcijska raziskava

Uvod: Skrb za zadostno hidracijo starostnikov je pogosto izražena, vendar v praksi velikokrat pozabljena. Z raziskavo smo želeli ugotoviti stanje hidracije pri starostnikih, starejših od 65 let, ki živijo v socialnovarstvenih institucijah v Mariboru in okolici. 
 Metode: V retrospektivni raziskavi smo ugotavljali vrednosti označevalcev dehidracije pri 107 starostnikih, starejših od 65 let. Med njimi je bilo 70 (65 %) žensk, povprečne starosti 84,1 let, in 37 (35 %) moških, povprečne starosti 80,4 let. Vzorec je zajemal starostnike, napotene v ambulanto za Internistično nujno pomoč Univerzitetnega kliničnega centra Maribor v obdobju od 1. 11. 2013 do 24. 1. 2014. Analizirali smo laboratorijske rezultate, zbrane v medicinsko-informacijskem sistemu. Kriterije dehidracije so predstavljali: natrij v serumu nad 145 mmol/L, sečnina nad 20 mg/ml oz. razmerje sečnina/kreatinin nad 20 : 1. 
 Rezultati: Raziskava je potrdila prisotnost povišanih vrednosti označevalcev dehidracije pri 73,8 % obravnavanih starostnikov. En kriterij dehidracije je dosegalo 35 starostnikov, dva kriterija 39 in tri kriterije 5 starostnikov.
 Diskusija in zaključek: Ugotovili smo, da povišane vrednosti označevalcev dehidracije ne dajo zanesljivega odgovora o stanju hidracije starostnikov, saj se le-ta lahko glede na uporabljene kriterije preceni ali podceni. Za boljšo oceno hidracije je v nadaljnjih raziskavah potrebno uporabiti natančnejše označevalce v kombinaciji s starostnikovimi kliničnimi znaki in anamnestičnimi podatki.

Anatomy of the InfO system: applying object-oriented concept to a web-based information sharing system

As the widespread use of the consumer electronics, the information is available around us. The information is generated rapidly but there is no effective and general format to organise it. We propose a concept of information object (InfO). The design goal of the InfO is to make the information self-contained, portable, extensible, and reusable. The InfO is based on the object oriented model, which combines the data and method in a single entity. In this paper, we explain how the application developer uses the InfO model to construct an information sharing platform rapidly. Through the platform, the information consumer can use the characteristics of the portability of the InfO to share information with one another. Also, the specification of the InfO can be a reference for the internet application development in the future.

Can credit scoring models prevent default payments in the banking industry in the period of financial crisis?

Credit scoring is a scientific method of assessing the credit risk associated with new credit applications as well as for monitoring of the credit risk in the process of the loan payment. Therefore credit scoring models developed in the banks based on their internal information system, as well as the credit info system in the country, can help the banks to ensure more consistent underwriting and can provide management with a more insightful measure of credit risk. While credit scoring could be a valuable risk management tool in virtually any bank setting, it is probably not wide accepted in the banks with more fundamental underwriting problems such as inexperienced loan officers, inadequate credit procedures, underdeveloped internal and external credit info – system , persistent arrears problems, etc. However credit scoring is only useful , and can make reliable predictions , if the credit scoring models are properly made, data base updated and credit scoring limitations are properly understood, which is very difficult in the turbulent economic environment as it is the world economy in the recent years. Therefore, the paper objective is to analyze if the banking industry can prevent credit default payments through the implementation of the credit scoring models and what are the parameters and the weights that need to be incorporated, so that the models to be more effective in the period of financial crises.

A model to prioritize access to elective surgery on the basis of clinical urgency and waiting time

BackgroundPrioritization of waiting lists for elective surgery represents a major issue in public systems in view of the fact that patients often suffer from consequences of long waiting times. In addition, administrative and standardized data on waiting lists are generally lacking in Italy, where no detailed national reports are available. This is true although since 2002 the National Government has defined implicit Urgency-Related Groups (URGs) associated with Maximum Time Before Treatment (MTBT), similar to the Australian classification. The aim of this paper is to propose a model to manage waiting lists and prioritize admissions to elective surgery.MethodsIn 2001, the Italian Ministry of Health funded the Surgical Waiting List Info System (SWALIS) project, with the aim of experimenting solutions for managing elective surgery waiting lists. The project was split into two phases. In the first project phase, ten surgical units in the largest hospital of the Liguria Region were involved in the design of a pre-admission process model. The model was embedded in a Web based software, adopting Italian URGs with minor modifications. The SWALIS pre-admission process was based on the following steps: 1) urgency assessment into URGs; 2) correspondent assignment of a pre-set MTBT; 3) real time prioritization of every referral on the list, according to urgency and waiting time. In the second project phase a prospective descriptive study was performed, when a single general surgery unit was selected as the deployment and test bed, managing all registrations from March 2004 to March 2007 (1809 ordinary and 597 day cases). From August 2005, once the SWALIS model had been modified, waiting lists were monitored and analyzed, measuring the impact of the model by a set of performance indexes (average waiting time, length of the waiting list) and Appropriate Performance Index (API).ResultsThe SWALIS pre-admission model was used for all registrations in the test period, fully covering the case mix of the patients referred to surgery. The software produced real time data and advanced parameters, providing patients and users useful tools to manage waiting lists and to schedule hospital admissions with ease and efficiency. The model protected patients from horizontal and vertical inequities, while positive changes in API were observed in the latest period, meaning that more patients were treated within their MTBT.ConclusionThe SWALIS model achieves the purpose of providing useful data to monitor waiting lists appropriately. It allows homogeneous and standardized prioritization, enhancing transparency, efficiency and equity. Due to its applicability, it might represent a pragmatic approach towards surgical waiting lists, useful in both clinical practice and strategic resource management.

A web-based system to manage elective waiting lists: efficiency and equity issues

Waiting lists for elective surgery are a topical issue in many publicly funded health systems. Decision makers should, therefore, state rules to prioritise access in order to attain both efficiency and equity. Efficiency requires that resources should be allocated to satisfy maximum social benefit. Equity means that everyone should receive healthcare at the right moment, i.e. before his/her conditions worsen (horizontal equity, depending on 'urgency'), and that different needs should receive different answers (vertical equity). In Italian National Health System since 2002 guidelines suggest classifying elective surgery referrals into categories (urgency-related groups, URGs) associated with a maximum waiting time within which the patient should receive treatment. The Surgical Waiting List Info System program is geared at setting and testing an experimental web-based informative system for prioritising elective surgery admissions belonging to different URGs and producing reports about the performance of waiting lists in terms of efficiency and equity indexes.

INFO SYSTEM FOR ANALYSIS OF TECHNICAL AND ECONOMIC DEVELOPMENT OF THE USE OF WOOD FUEL

EU Integration raises new requirements to energy sector, including municipal energy sector and improvement of local planning. Important role is assigned to development of energy infrastructure, use of renewable energy sources and energy efficiency. In order to use financial support from EU Structural funds for regional energy development, qualified applications will have to be developed in adequacy with the requirements for the use and control of EU Structural funds. The latter should be developed in the context of regional development programs (including energy sector development), which should be based on info systems. The Laboratory of Regional Energy Development at LEI is developing integrated info system "TAUSA" for this purpose. This info system is formed as server of data bases with respective bases and additional analysis modules. Information for the consumers of info systems could be available at Internet website. Besides indicators on district heating, "TAUSA" will accumulate data on distribution and end use of renewable energy sources at regional level, which permits to assess main macroeconomic indicators in the development of this economic activity. Matrix model for economic activity of preparing local fuel will enable to evaluate inter-branch links for district heating sector and the role of local fuel production in Gross Domestic Product (GDP) creating process. The macroeconomic model under development will help to assess economic benefit from the use of renewable energy sources in the region, including the facts that it improves employment, increases the flow of taxes to municipal budget, paid by the companies employed in this sector, give new business development opportunities.

Technology and Computing in the Surgical Suite: Key Features of an OR Management Information System and Opportunities for the Future

To the Editor: We were very pleased to read that a new section on technology, computing, and simulation has been added to Anesthesia & Analgesia(1). As the authors point out, medical informatics, expert systems, and distributed computing are examples of applied information technology in the surgical suite. While a decade ago most surgical suites had computerized billing and scheduling, now OR computer management information systems (OR Mgt Info Systems) are increasingly being used as a tool to provide clinical, financial, and materials data for better decision-making. Facilities can either invest in a niche OR Mgt Info System (specifically designed for surgical services and likely to have good functionality and ease of use), or adopt a module that is part of a larger hospital-wide administrative system. In order to highlight opportunities for study in this area, we report the results of a written survey questionnaire completed by a convenience sample of 26 OR managers. The objective was to learn more about the impressions of users of OR Mgt Info Systems as to 1) the relative importance of different functions of OR Mgt Info Systems in achieving managerial goals, and 2) how well commercially available systems are meeting the needs of OR managers. The Human Subjects Committee at Stanford University approved this study. The 26 respondents had a mean age of 46 (sd ±7) yr, 50% were female, with 9 (sd ±7) yr of OR management experience, and worked in facilities with 13 (sd ±13) ORs. Fifteen of the 26 managers surveyed worked at facilities with less than 7 ORs. We found that surgical case scheduling, customized report generation, and having onsite access via multiple terminals were deemed as the three most important functions. Interestingly, we also found that many important functions of OR Mgt Info Systems, such as a patient tracking system, ordering supplies, inventory control, case cost tracking, and nurse intraoperative documentation are currently either not meeting the needs of OR managers or completely unavailable to them. This was also true at smaller facilities, having less than 7 ORs (Table 1).Table 1: Importance and Availability of OR Mgt Info System FunctionsAs available commercial products do not offer many of the perceived necessary management functions, facilities may develop their own homegrown systems. Some of these functions, such as staff scheduling (2), block time allocation (3), and patient instructions (4) have been analyzed and could be implemented in the next generation of OR Mgt Info Systems. Return on this investment may come from lost supply charges recovered, savings on inventory carrying cost by increasing inventory turns per year, and increase in revenue from better case scheduling and OR efficiency. The editorial by Weinger et al. prompted us to report the results of our survey regarding the impressions of OR managers as to the key features of an OR Mgt Info System and unrealized opportunities to design and successfully implement new management technology in the surgical suite.

A Walk-Up-and-Use Information System for the Sydney Olympics: A Case Study in User-Centered Design

The info information retrieval system was designed and developed for the XXVII Olympic Summer Games held in Sydney, Australia in September 2000. info provided journalists and broadcasters with information for planning their days at the games and producing their coverage of Olympic events. The user-centered design (UCD) team from the IBM Storage Systems Group was invited to work with the info system for the 2000 games and was able to do extensive UCD work, including working with journalists, broadcasters, and sports researchers from North America, Europe, and Asia. Throughout the development cycle the UCD team worked closely with the info programming team located in Madrid, Spain and with other teams in Sydney, Australia. Later, the UCD team joined a large cast of volunteers and professionals in providing support for info at the Sydney games. This opportunity allowed the UCD team to make observations and collect data on the usability of the system, and these indicate that info was indeed easy to use and that customers were very satisfied with the system. info's success was due to an extensive multidisciplinary team that included visual designers, human factors and human-computer interaction specialists, user research specialists, developers, marketers, IBM executives, and an active customer sponsor. The project demonstrates that application of UCD methods can improve product usability even when challenged with extremely dispersed teams and immovable deadlines.
