Dual anterior descending coronary artery associated with coronary artery disease

The patient is a male with risk factors for coronary artery disease, who was referred for cardiac catheterization after acute myocardial infarction in the inferior wall. The patient underwent transluminal coronary angioplasty in the right coronary artery with successful stent implantation.

Quantificação da massa infartada do ventrículo esquerdo pela ressonância magnética cardíaca: comparação entre a planimetria e o método de escore visual semi-quantitativo

OBJETIVO: Validar um novo método de escore visual semi-quantitativo contra a planimetria digital quantitativa para a determinação da massa infartada do ventrículo esquerdo pela ressonância magnética cardíaca com técnica de realce tardio. MÉTODO: Estudados 77 pacientes com infarto miocárdico prévio em aparelho de ressonância magnética de 1,5T utilizando técnica de realce tardio para avaliação da viabilidade miocárdica e cálculo da massa infartada. Para avaliação da função ventricular esquerda pelo método de Simpson utilizamos técnica de cine-ressonância. O cálculo da massa infartada foi realizado nas imagens de realce tardio de duas formas: planimetria e método de escore. Utilizamos métodos de regressão linear simples, correlação e concordância entre métodos e observadores segundo a análise de Bland-Altman. RESULTADOS: Em todos os 77 pacientes as áreas de infarto foram detectadas pela ressonância magnética cardíaca utilizando a técnica de realce tardio. O tamanho do infarto medido pela planimetria foi semelhante ao obtido pelo método de escore, com a média das diferenças entres as medidas de apenas 1,03% da massa do ventrículo esquerdo. As variabilidades inter (0,41%) e intra-observador (0,34%) evidenciaram excelente reprodutibilidade do método de escore. A massa infartada apresentou boa correlação com a fração de ejeção e volumes distólico e sistólico finais indexados, r=-0,76, r=0,63 e r=0,67, respectivamente. CONCLUSÃO: A avaliação de pacientes com infarto agudo do miocárdio prévio pela ressonância magnética cardíaca, utilizando a técnica de realce tardio, permite a determinação reprodutível do tamanho do infarto, tanto pelo método de planimetria, quanto pelo modelo semi-quantitativo de escore.

The Irish Pub: past, present – whither the future?

The purpose of this research is to examine the main economic, legislative, and socio- cultural factors that are currently influencing the pub trade in Ireland and their specific impact on a sample of publicans in both Galway city and county. In approaching this task the author engaged in a comprehensive literature review on the origin, history and evolution of the Irish pub; examined the socio-cultural and economic role of the public house in Ireland and developed a profile of the Irish pub by undertaking a number of semi-structured interviews with pub owners from the area. In doing so, the author obtained the views and opinions of the publicans on the current state of their businesses, the extent to which patterns of trade have changed over recent years, the challenges and factors currently influencing their trade, the actions they believed to be necessary to promote the trade and address perceived difficulties and how they viewed the future of the pub business within the framework of the current regulatory regime. In light of this research, the author identified a number of key findings and put forward a series of recommendations designed to promote the future success and development of the pub trade in Ireland. The research established that public houses are currently operating under a very unfavourable regulatory framework that has resulted in the serious decline of the trade over the last decade. This decline appears to have coincided initially with the introduction of the ban on smoking in the workplace and was exacerbated further by the advent of more severe drink-driving laws, especially mandatory breath testing. Other unfavourable conditions include the high levels of excise duty, value added tax and local authority commercial rates. In addition to these regulatory factors, the research established that a major impediment to the pub trade is the unfair competition from supermarkets and other off-licence retail outlets and especially to the phenomenon of the below-cost selling of alcohol. The recession has also been a major contributory factor to the decline in the trade as also has been the trend towards lifestyle changes and home drinking mirroring the practice in some continental European countries.

Development of a semi-automatic self learning pattern recognition system for the control of electronic boards

This project was funded under the Applied Research Grants Scheme administered by Enterprise Ireland. The project was a partnership between Galway - Mayo Institute of Technology and an industrial company, Tyco/Mallinckrodt Galway. The project aimed to develop a semi - automatic, self - learning pattern recognition system capable of detecting defects on the printed circuits boards such as component vacancy, component misalignment, component orientation, component error, and component weld. The research was conducted in three directions: image acquisition, image filtering/recognition and software development. Image acquisition studied the process of forming and digitizing images and some fundamental aspects regarding the human visual perception. The importance of choosing the right camera and illumination system for a certain type of problem has been highlighted. Probably the most important step towards image recognition is image filtering, The filters are used to correct and enhance images in order to prepare them for recognition. Convolution, histogram equalisation, filters based on Boolean mathematics, noise reduction, edge detection, geometrical filters, cross-correlation filters and image compression are some examples of the filters that have been studied and successfully implemented in the software application. The software application developed during the research is customized in order to meet the requirements of the industrial partner. The application is able to analyze pictures, perform the filtering, build libraries, process images and generate log files. It incorporates most of the filters studied and together with the illumination system and the camera it provides a fully integrated framework able to analyze defects on printed circuit boards.
