Design of a two-level Adaptive Multi-Agent System for malaria vectors driven by an ontology.

BACKGROUND: The understanding of heterogeneities in disease transmission dynamics as far as malaria vectors are concerned is a big challenge. Many studies while tackling this problem don't find exact models to explain the malaria vectors propagation. METHODS: To solve the problem we define an Adaptive Multi-Agent System (AMAS) which has the property to be elastic and is a two-level system as well. This AMAS is a dynamic system where the two levels are linked by an Ontology which allows it to function as a reduced system and as an extended system. In a primary level, the AMAS comprises organiz

Modeling and detection of respiratory-related outbreak signatures.

BACKGROUND: Time series methods are commonly used to detect disease outbreak signatures (e.g., signals due to influenza outbreaks and anthrax attacks) from varying respiratory-related diagnostic or syndromic data sources. Typically this involves two components: (i) Using time series methods to model the baseline background distribution (the time series process that is assumed to contain no outbreak signatures), (ii) Detecting outbreak signatures using filter-based time series methods. METHODS: We consider time series models for chest radiograph data obtained from Midwest children's emergency

Utilities of the post-anesthesia state derived by the standard gamble method in surgical patients.

BACKGROUND: There are no published utilities for the post-anesthesia state obtained by the standard gamble method (SG). METHODS: We obtained utilities for postoperative pain, nausea, vomiting, urinary retention and myalgia from 100 adults prior to elective surgery using SG. RESULTS: 20% of volunteer participants could not demonstrate a satisfactory understanding of the SG process. Median utilities for each adverse effect were all very close to 1.0, and no statistically significant differences were found between them. CONCLUSION: Our results suggest that the avoidance of anesthesia related s

A Severe Acute Respiratory Syndrome Extranet: supporting local communication and information dissemination.

BACKGROUND: The objective of this study was to explore the use and perceptions of a local Severe Acute Respiratory Syndrome (SARS) Extranet and its potential to support future information and communication applications. The SARS Extranet was a single, managed electronic and limited access system to manage local, provincial and other SARS control information. METHODS: During July, 2003, a web-based and paper-based survey was conducted with 53 SARS Steering Committee members in Hamilton. It assessed the use and perceptions of the Extranet that had been built to support the committee during the

Handheld computers and the 21st century surgical team: a pilot study.

BACKGROUND: The commercial development and expansion of mobile phone networks has led to the creation of devices combining mobile phones and personal digital assistants, which could prove invaluable in a clinical setting. This pilot study aimed to look at how one such device compared with the current pager system in facilitating inter-professional communication in a hospital clinical team. METHODS: The study looked at a heterogeneous team of doctors (n = 9) working in a busy surgical setting at St. Mary's Hospital in London and compared the use of a personal digital assistant with mobile phon

Characterization of digital medical images utilizing support vector machines.

BACKGROUND: In this paper we discuss an efficient methodology for the image analysis and characterization of digital images containing skin lesions using Support Vector Machines and present the results of a preliminary study. METHODS: The methodology is based on the support vector machines algorithm for data classification and it has been applied to the problem of the recognition of malignant melanoma versus dysplastic naevus. Border and colour based features were extracted from digital images of skin lesions acquired under reproducible conditions, using basic image processing techniques. Two

Doublet method for very fast autocoding.

BACKGROUND: Autocoding (or automatic concept indexing) occurs when a software program extracts terms contained within text and maps them to a standard list of concepts contained in a nomenclature. The purpose of autocoding is to provide a way of organizing large documents by the concepts represented in the text. Because textual data accumulates rapidly in biomedical institutions, the computational methods used to autocode text must be very fast. The purpose of this paper is to describe the doublet method, a new algorithm for very fast autocoding. METHODS: An autocoder was written that transfo

A computer decision aid for medical prevention: a pilot qualitative study of the Personalized Estimate of Risks (EsPeR) system.

BACKGROUND: Many preventable diseases such as ischemic heart diseases and breast cancer prevail at a large scale in the general population. Computerized decision support systems are one of the solutions for improving the quality of prevention strategies. METHODS: The system called EsPeR (Personalized Estimate of Risks) combines calculation of several risks with computerisation of guidelines (cardiovascular prevention, screening for breast cancer, colorectal cancer, uterine cervix cancer, and prostate cancer, diagnosis of depression and suicide risk). We present a qualitative evaluation of its

Backpropagation and adaptive resonance theory in predicting suicidal risk.

The ability of backpropagation and adaptive resonance theory (ART) neural networks to predict the probability of complete suicide, within a two year span, in major psychiatric patients was investigated. Variables associated with suicide risk were collected from the files of 161 hospitalized psychiatric patients with a 10 year or greater history of illness. 84 patients were hospitalized due to suicide attempts and 77 had no previous suicide attempts or ideations. Suicide attempts were rated as medically serious suicide attempts (MSSA) or non-MSSA and used for training the systems. The ability o

An expert system for the computer-aided diagnosis of dizziness and vertigo.

We have developed an expert system to assist in the diagnostic work-up of otoneurological cases. Our otoneurological expert system ONE takes advantage of both patient history and clinical measurement data in order to supply all possible information about the patient's symptoms and other findings. This paper presents ONE after its initial stage of development, which included tests with numerous patients.

A method for early detection of abnormal trends in serial clinical examination results over time.

In this paper we describe a method for the early detection of changing health conditions which may eventually lead to serious disease. The method makes use of health screening test results accumulated for individuals and can be applied to those who have taken at least four health examinations. The degree of abnormality is calculated using a logistic regression equation. The variables defining the equation are selected by factor analysis and a stepwise variable selection method based on the likelihood ratio criterion. Statistical estimates include linear regression coefficients, isotonic regres

Analysis of the occurrence of anencephalic stillbirths in the Fylde Peninsula, 1956--1967.

Computer-based statistical signal methods have been applied to the analysis of case-occurrence time and location data from a 12-year complete series of anencephalic stillbirths in the Fylde peninsula of Lancashire. In the absence of any certainty about causative or contributory factors in these occurrences, the primary questions are if the underlying process is Poisson, or if there is evidence of a seasonal influence, and if any regional differences or communicable factors can be identified. With the limited case numbers (124) most small-sample statistical tests were not sufficiently informati

Short- and Long-Term Outcomes of Hematologic Malignancy Patients After Cardiopulmonary Resuscitation: Experience of a Large Oncology Center.

The Architect of Trust: Dr Tom Ferguson's Legacy.

UnlabelledThis article serves as a formal tribute to the legacy of Dr Tom Ferguson and his foundational 2007 white paper on the "e-patient." Despite its widespread influence, Dr Ferguson's original vision has often been internalized by the broader medical community without clear historical attribution, leading to a drift in the term's original meaning. This article restores the intellectual genealogy of the "e-patient" as defined by Dr Ferguson as "equipped, enabled, empowered, and engaged." We argue for the continued relevance of his "quiet giant" leadership. By formalizing Dr Ferguson's foun
