Nos ?ltimos dois s?culos, ocorreram importantes mudan?as demogr?ficas acompanhadas por um crescimento da expectativa m?dia de vida, aumentando a popula??o com mais de 60 anos. Como consequ?ncia desse processo, houve o aumento na incid?ncia das doen?as associadas ao envelhecimento, conhecidas como doen?as neurodegenerativas, que podem afetar partes cerebrais relacionadas ao sistema olfat?rio, levando a uma perda prevalente da percep??o do olfato. A avalia??o da capacidade olfativa pode ser realizada de diversas formas, atrav?s de m?todos espec?ficos, com o aux?lio de t?cnicas de neuroimagem ou de testes cl?nicos. H? dois tipos de testes cl?nicos, os eletrofisiol?gicos, baseados em potenciais olfativos detectados no c?rebro, e os psicof?sicos, que avaliam a capacidade olfativa, ou seja, o limiar olfativo, a discrimina??o e a identifica??o de odores. Estes ?ltimos, por?m, s?o feitos de forma manual, o que torna o procedimento sujeito ? perda de informa??es e contamina??o ambiental. Em conjunto com esses m?todos de avalia??o, existem ainda sistemas/equipamentos (olfat?metros) que auxiliam na avalia??o olfativa, fornecendo o est?mulo olfativo. Este trabalho prop?e o desenvolvimento de um sistema de entrega controlada de est?mulo olfativo, chamado olfat?metro. O sistema desenvolvido ? avaliado de acordo com tr?s par?metros, s?o eles: fluxo de ar adequado para uma suficiente exposi??o ao est?mulo olfativo, reprodutibilida deste est?mulo e resposta temporal do sistema. Os par?metros fluxo de ar e reprodutibilidade do est?mulo olfativo s?o analisados atrav?s de processamento digital de imagens, substituindo a subst?ncia odor?fera por uma subst?ncia corante e borrifando-a em um papel branco, gerando amostras que s?o digitalizadas. A resposta temporal do sistema ? medida atrav?s de um sensor de oxig?nio. Por fim, ? proposta uma interface que al?m de controlar o olfat?metro, reproduz o teste olfativo Sniffin? Sticks, possibilitando ao m?dico a realiza??o da avalia??o olfativa atrav?s de um computador. Assim sendo, a contribui??o da presente disserta??o reside no desenvolvimento de um m?todo e um sistema eletr?nico que visam aumentar o grau de automa??o do procedimento de entrega controlada de est?mulo olfativo e com isto, aumentar a confiabilidade dos resultados e a capacidade de repetibilidade do processo. Over the past two centuries, significant demographic changes have occurred accompanied by a rise in average life expectancy, increasing the population over 60 years. As a consequence of this process, there has been an increase in the incidence of aging-related diseases (neurodegenerative diseases), which can affect olfactoryrelated brain parts, leading to a prevalent loss of smell perception in these diseases. The assessment of olfactory capacity is performed in several ways, can be by specific methods, with the aid of neuroimaging techniques or through clinical tests. There are two types of clinical tests, electrophysiological, based on olfactory potentials detected in the brain, which gives this method a high cost of execution and day-to-day unfeasibility, and psychophysicists, which assess olfactory capacity, that is, the olfactory threshold, the discrimination and the identification of odors. However, these methods are carried out manually, which makes the procedure subject to information loss and environmental contamination. In conjunction with these evaluation methods, there are also systems/equipment (olfactometers) that assist in the olfactory evaluation, providing the olfactory stimulus. Given this scenario, this work proposes the development of a controlled delivery system of olfactory stimulus, called olfactometer. The developed system is evaluated according to three parameters, they are: adequate air flow for sufficient exposure to the olfactory stimulus, reproducible from this stimulus and the system?s temporal response. The parameters of air flow and reproducibility of the olfactory stimulus are analyzed through the processing of digital images, replacing an odorous substance with a coloring substance and spraying it on a white paper, generating the samples that are digitized. The system?s temporal response is measured using an oxygen sensor. To this end, an interface is proposed that, in addition to controlling the olfactometer, still reproducing the test Sniffin? Sticks, allows the doctor to carry out an evaluation of the olfactory evaluation through a computer. Therefore, a contribution of the present dissertation does not lie in the development of a method and an electronic system that aim to increase or decrease the degree of automation of the delivery procedure controlled by olfactory stimulus and, with that, increase the results indexes and the repeatability capacity. of the process.

Lower body positive pressure (LBPP) is an effective way of simulating hypogravity. This study measured the submaximal VO
2 , VCO2 and heart rate when walking on an LBPP treadmill at 1G and simulated Martian gravity (0.38G). Twelve healthy subjects with a mean age ± SD of 22.75 ± 5.38 yrs took part in this study with full consent. The LBPP box used was designed and built by the Microgravity Center. The subjects walked for 8 min at a control of 1G and then for another 8 min in simulated 0.38G 2 wks later. VO2 was 1.00 ± 0.61 L·min-1 at 1G and 0.68 ± 0.33 L·min-1 in the simulated 0.38G (P<0.05). Average caloric expenditure was significantly reduced at simulated Martian gravity (4.79 ± 2.80 kcal·min-1 ) when compared to the control (3.37 ± 1.49 Kcal·min-1 ) (P<0.05). The subjects' HR was reduced from 118.49 ± 15.07 beats·min-1 at 1G to 106.20 ± 11.17 beats·min-1 at simulated 0.38G (P<0.05). The average respiratory exchange ratio was significantly increased from 0.83 ± 0.13 to 1.14 ± 0.19 in simulated 0.38G (P<0.05), with no significant difference seen in VCO2 . Energy consumption was significantly decreased when walking in LBPP simulated hypogravity. Further research into LBPP physiology can be used to calibrate EVA suits and advise on exercise regimes for future astronauts. [ABSTRACT FROM AUTHOR]- Published

- Abstract
AIMS: This study aimed to evaluate the photo-electrocardiogram (photo-ECG), as an alternative tool to enable remote formative second opinion in cardiology. METHODS: Fifty paper electrocardiograms (ECGs) were photographed two times, the first using a Canon digital camera, 0.3 megapixel resolution, and the second using a Nokia mobile phone integrated camera, 2.0 megapixel resolution, resulting in 100 Photo-ECGs. A pilot study was responsible for determining the acquisition method. The 100 Photo-ECGs were randomized, encrypted and sent by e-mail to a remote cardiologist, while the 50 paper ECGs were delivered to him in person, without randomization. Gender and age were the only patient information made available to the specialist. RESULTS: Data analysis demonstrated a disagreement in 14 of 50 interpretations (28%) when comparing paper ECGs to the Canon camera photo-ECGs and in 13 of 50 interpretations (26%) when comparing paper ECGs to the Nokia camera photo-ECGs. The Kappa test revealed a fair agreement (Kappa=0.356) between interpretations when comparing the original ECGs to their respective photo-ECGs for both camera devices. CONCLUSIONS: The concordance between photo-ECGs and original tracings demonstrated that the method described herein has the potential for use as a tool to assist clinical practice, provided that the acquisition of photo-ECGs is adapted so as to improve exam images. Only with good to very good concordance between the original ECGs and photo-ECGs will remote formative second opinion be possible, giving better diagnostic and therapeutic options.
