Effects of an exercise training program in physical condition after liver transplantation in familial amyloidotic polyneuropathy: a case report

Introduction: Familial amyloidotic polyneuropathy (FAP) is a neurodegenerative disease that leads to sensory and motor polyneuropathies as well as functional limitations. So far, liver transplantation is the only treatment for FAP because the mutated protein causing the disease is mainly produced in the liver. With the increasing survival of transplant recipients, functional and cardiovascular problems as consequences of immunosuppressant side effects are increasing associated with sedentary lifestyles and/or retransplantation status. We sought to analyze the impact of exercise training programs on 1 FAP patient’s course long-term after liver transplantation. Methodology. A FAP patient (female; 49 years of age; body mass index 18.8 kg/m2) underwent a liver transplantation 133 months before assessment. She was assessed for body composition, isometric quadriceps muscle strength, functional capacity, fatigue, and levels of physical activity before and after a 6-month period of combined exercise training. Results: After the exercise training program, almost all variables were improved, namely, total body skeletal muscle mass, proximal femoral bone mineral density, quadriceps strength, maximal oxygen consumption on 6 minutes walk test (6mwt) or VO2peak, total ventilation on 6mwt, and fatigue. The improvement in distance on 6mwt (69.2 m) was clinically significant. Preintervention the levels of physical activity were below international recommendations for health; after the program they achieved the recommendations. Conclusion: The results showed an improvement in functional capacity with a decrease in future disability risk associated with a better lifestyle with respect to physical activity levels in 1 patient.

Fungi, bacteria and pollens seasonally quantified at 3 basic schools in Lisbon: evaluation of ventilation need

Nowadays, most individuals spend about 80% of their time indoor and, consequently, the exposure to the indoor environment becomes more relevant than to the outdoor one. Children spend most of their time at home and at school and evaluations of their indoor environment are important for the time-weighted exposure. Due to their airways still in development, children are a sensitive group with higher risk than adults. Larger impact in health and educational performance of children demand indoor air quality studies of schools. The aim of this study was to assess the children exposure to bioaerosols. A methodology based upon passive sampling was applied to evaluate fungi, bacteria and pollens; its procedures and applicability was optimized. An indoor air study by passive sampling represents an easier and cheaper method when comparing with the use of automatic active samplers. Furthermore, it is possible to achieve important quality information without interfering in the classroom activities. The study was conducted in three schools, representative of different environments in the Lisbon urban area, at three different periods of the year to obtain a seasonal variation, to estimate the variability through the city and to understand the underneath causes. Fungi and bacteria were collected indoor and outdoor of the classrooms to determine the indoor/outdoor ratios and to assess the level of outdoor contamination upon the indoor environment. The children's exposure to pollen grains inside the classrooms was also assessed.

A formação em mediação de conflitos no desenvolvimento profissional dos assistentes operacionais, em escola pública do 1º ciclo do ensino básico

O objetivo da pesquisa pretende verificar se há um contributo da formação em mediação no desenvolvimento de conhecimentos nessa área e na mudança de atitude nos Assistentes Operacionais (AO), face à resolução de conflitos entre alunos. Os recreios das escolas do 1.º Ciclo do Ensino Básico (1.ºCEB) são os locais onde ocorre a quase totalidade dos conflitos entre alunos (Fernández, 2007; Oliveira, 2007; Rosa, 2007). Esses recreios são supervisionados pelos AO, os quais devem ter formação específica em estratégias de resolução de conflitos. A mediação é apontada como a melhor estratégia na abordagem dos conflitos escolares, perspetivando melhoria na convivência escolar e na construção de um clima escolar positivo, propício à eficácia da educação. A estratégia de pesquisa baseia-se num estudo de intervenção com uma amostra de conveniência, simultaneamente qualitativo e quantitativo. Os dados foram recolhidos por questionário, por levantamento dos conhecimentos anteriores e posteriores à formação e por entrevistas aos participantes. No estudo participaram sete AO. Os resultados revelaram que os AO desenvolveram conhecimentos sobre mediação e percecionaram em si mesmos mudanças de atitude face à resolução de conflitos entre alunos. Os resultados ainda revelaram que os AO se sentem desvalorizados no meio escolar, mas motivados na interação com os alunos. Concluiu-se que a formação em mediação de conflitos oferece um contributo significativo no desenvolvimento de conhecimentos sobre mediação e facilita uma mudança de atitude na resolução de conflitos entre alunos. Concluiu-se também que os AO estão conscientes do seu papel educativo e que têm sugestões pertinentes de melhoria.ABSTRAT This research intends to evaluate whether training in mediation contributes for the development of knowledge in this area, and for changes in attitude, when Operational Assistants (OAs) sort out conflicts between students. The playgrounds of the schools of the 1st Cycle of Basic Education (1stCEB) are the places where almost the conflicts between students happen. These playgrounds are supervised by OAs, which must have specific training in conflict resolution strategies. Mediation is considered the best strategy for addressing students’ conflicts in order to improve school coexistence and positive climate, conducive to the effectiveness of education. The research strategy is based on an intervention study with a convenience sample, both qualitative and quantitative. Data was collected by questionnaire, assessment of knowledge before and after training and final interviews. The participants were 7 OAs. The results revealed the development of knowledge about mediation, who perceives themselves as changing attitudes towards conflicts resolution between students. The results also revealed that the OAs feel devalued, but motivated when interacting to students. Training in conflict mediation offers a significant contribution in the development of knowledge about mediation and facilitates a change of attitude in sorting out conflicts between students. It was also concluded that the OAs are aware of their educational role and have relevant suggestions for improvement.

The impact of exercise training on liver transplanted familial amyloidotic polyneuropathy (FAP) patients

Liver transplantation is nowadays the only effective answer to adjourn the outcome of functional limitations associated with familial amyloidotic polyneuropathy (FAP), a neurodegenerative disease characterized by sensory and motor polyneuropathies. Nevertheless, there is a detrimental impact associated with the after-surgery period on the fragile physical condition of these patients. Exercise training has been proven to be effective on reconditioning patients after transplantation. However, the effects of exercise training in liver transplanted FAP patients have not been scrutinized yet.

Radiographers and radiation protection: education, training and CPD

The increasing use of ionizing radiation for medical purposes emphasizes the concern about safety and justification of using ionizing radiation. This is linked with the use of new and high-dose X-ray technology (particularly CT). According to the UNSCEAR 2010 Report the total number of diagnostic medical examinations (both medical and dental) is estimated to have risen from 2.4 billion (period 1991–1996) to 3.6 billion (period 1997– 2008) - a marked increase in collective doses. An appropriate use of technology aiming diagnostic or therapy and respecting the ALARA principle is a mandatory requisite to safely perform any radiological procedure. Radiation protection is thus, a concern of all specialists in the radiology field ( radiologists, radiographers, medical physicists, among other professional groups). The importance of education and training of these professionals in reducing patients’ doses while maintaining the desired level of quality in medical exposures, as well as precise therapeutic treatments is well recognized. Education, training and continuing professional development (CPD) constitute a triad pointing towards the radiographers’ development of competences in the radiation protection field. This presentation excludes the radiographer role and competences in the fields of ultrasonography and MRI.

Monte Carlo simulation of the basic features of the GE Millennium MG single photon emission computed tomography gamma camera

Objective - To describe and validate the simulation of the basic features of GE Millennium MG gamma camera using the GATE Monte Carlo platform. Material and methods - Crystal size and thickness, parallel-hole collimation and a realistic energy acquisition window were simulated in the GATE platform. GATE results were compared to experimental data in the following imaging conditions: a point source of 99mTc at different positions during static imaging and tomographic acquisitions using two different energy windows. The accuracy between the events expected and detected by simulation was obtained with the Mann–Whitney–Wilcoxon test. Comparisons were made regarding the measurement of sensitivity and spatial resolution, static and tomographic. Simulated and experimental spatial resolutions for tomographic data were compared with the Kruskal–Wallis test to assess simulation accuracy for this parameter. Results - There was good agreement between simulated and experimental data. The number of decays expected when compared with the number of decays registered, showed small deviation (≤0.007%). The sensitivity comparisons between static acquisitions for different distances from source to collimator (1, 5, 10, 20, 30cm) with energy windows of 126–154 keV and 130–158 keV showed differences of 4.4%, 5.5%, 4.2%, 5.5%, 4.5% and 5.4%, 6.3%, 6.3%, 5.8%, 5.3%, respectively. For the tomographic acquisitions, the mean differences were 7.5% and 9.8% for the energy window 126–154 keV and 130–158 keV. Comparison of simulated and experimental spatial resolutions for tomographic data showed no statistically significant differences with 95% confidence interval. Conclusions - Adequate simulation of the system basic features using GATE Monte Carlo simulation platform was achieved and validated.

Através de um teste com 21 questões, passado antes e após a formação em Geometria, avaliaram-se os estudantes num conjunto de categorias. Os resultados revelam que, embora os estudantes manifestem conhecimentos de conceitos elementares à partida, com percentagens em torno dos 70%, e evolução nas três escolas, com aumentos médios de 5%, revelam, ainda, aspetos críticos relativos a conceitos básicos contemplados no teste.

The influence of experience and training in a group of novice observers: a jackknife alternative free-response receiver operating characteristic analysis

Purpose - The study evaluates the pre- and post-training lesion localisation ability of a group of novice observers. Parallels are drawn with the performance of inexperienced radiographers taking part in preliminary clinical evaluation (PCE) and ‘red-dot’ systems, operating within radiography practice. Materials and methods - Thirty-four novice observers searched 92 images for simulated lesions. Pre-training and post-training evaluations were completed following the free-response the receiver operating characteristic (FROC) method. Training consisted of observer performance methodology, the characteristics of the simulated lesions and information on lesion frequency. Jackknife alternative FROC (JAFROC) and highest rating inferred ROC analyses were performed to evaluate performance difference on lesion-based and case-based decisions. The significance level of the test was set at 0.05 to control the probability of Type I error. Results - JAFROC analysis (F(3,33) = 26.34, p < 0.0001) and highest-rating inferred ROC analysis (F(3,33) = 10.65, p = 0.0026) revealed a statistically significant difference in lesion detection performance. The JAFROC figure-of-merit was 0.563 (95% CI 0.512,0.614) pre-training and 0.677 (95% CI 0.639,0.715) post-training. Highest rating inferred ROC figure-of-merit was 0.728 (95% CI 0.701,0.755) pre-training and 0.772 (95% CI 0.750,0.793) post-training. Conclusions - This study has demonstrated that novice observer performance can improve significantly. This study design may have relevance in the assessment of inexperienced radiographers taking part in PCE or commenting scheme for trauma.
