Temas de investigação em direitos humanos para o século XXI
Edição comemorativa do 10.º aniversário do Mestrado em Direitos Humanos da Universidade do Minho.Este livro é uma celebração do ensino e da investigação em direitos humanos que têm vindo a ser desenvolvidos, na Escola de Direito da Universidade do Minho, há já mais de uma década. A sua publicação num momento em que se avolumam os riscos para valores fundamentais subjacentes à proteção dos direitos humanos – como a igualdade e a não discriminação, a proibição da escravatura e de tratamentos cruéis, desumanos e degradantes, a liberdade de religião ou crença, entre muitos outros –, torna-o especialmente oportuno. Os sinais de aparente retrocesso no consenso das nossas sociedades a respeito desses valores – visíveis no triunfo político de discursos abertamente racistas, xenófobos, sexistas, etc. – recordam-nos que, também no mundo ocidental, os direitos humanos são um work in progress, não um dado adquirido. Os novos riscos para a dignidade da pessoa humana associados aos avanços tecnológicos andam de par com velhas formas de subalternização e de opressão. O campo para a reflexão crítica é muito vasto. Os temas que hoje (pre)ocupam académicos, decisores políticos e ativistas de direitos humanos são também aqueles que estruturam o plano de estudos do Mestrado em Direitos Humanos da Universidade do Minho. Todos estes temas surgem ao longo do presente livro, que reúne contributos de muitos dos membros da comunidade científica e académica que o Mestrado em Direitos Humanos mobilizou e ajudou a dinamizar ao longo da última década, entre docentes do Mestrado, colaboradores em júris de provas públicas e/ou na orientação de mestrandos, oradores convidados e estudantes. Os textos aqui reunidos refletem bem as sinergias interdisciplinares, interinstitucionais e inter-nacionais que o Mestrado em Direitos Humanos foi capaz de criar, não apenas pela variedade de campos disciplinares representados – Direito, Filosofia, Relações Internacionais, Antropologia –, mas também pela participação de autores que são docentes e/ou investigadores em diversas instituições nacionais e estrangeiras, como a Faculdade de Direito da Universidade do Porto, a Faculdade de Economia da Universidade de Coimbra, a Universidade Federal da Paraíba e a Pontifícia Universidade Católica de São Paulo.info:eu-repo/semantics/publishedVersio
Post-intervention Status in Patients With Refractory Myasthenia Gravis Treated With Eculizumab During REGAIN and Its Open-Label Extension
OBJECTIVE: To evaluate whether eculizumab helps patients with anti-acetylcholine receptor-positive (AChR+) refractory generalized myasthenia gravis (gMG) achieve the Myasthenia Gravis Foundation of America (MGFA) post-intervention status of minimal manifestations (MM), we assessed patients' status throughout REGAIN (Safety and Efficacy of Eculizumab in AChR+ Refractory Generalized Myasthenia Gravis) and its open-label extension. METHODS: Patients who completed the REGAIN randomized controlled trial and continued into the open-label extension were included in this tertiary endpoint analysis. Patients were assessed for the MGFA post-intervention status of improved, unchanged, worse, MM, and pharmacologic remission at defined time points during REGAIN and through week 130 of the open-label study. RESULTS: A total of 117 patients completed REGAIN and continued into the open-label study (eculizumab/eculizumab: 56; placebo/eculizumab: 61). At week 26 of REGAIN, more eculizumab-treated patients than placebo-treated patients achieved a status of improved (60.7% vs 41.7%) or MM (25.0% vs 13.3%; common OR: 2.3; 95% CI: 1.1-4.5). After 130 weeks of eculizumab treatment, 88.0% of patients achieved improved status and 57.3% of patients achieved MM status. The safety profile of eculizumab was consistent with its known profile and no new safety signals were detected. CONCLUSION: Eculizumab led to rapid and sustained achievement of MM in patients with AChR+ refractory gMG. These findings support the use of eculizumab in this previously difficult-to-treat patient population. CLINICALTRIALSGOV IDENTIFIER: REGAIN, NCT01997229; REGAIN open-label extension, NCT02301624. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that, after 26 weeks of eculizumab treatment, 25.0% of adults with AChR+ refractory gMG achieved MM, compared with 13.3% who received placebo
Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world
Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.
Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.
Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.
Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.
Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
Influence of the geometry on the numerical simulation of the cooling kinetics of cucumbers
In this paper, the effect of the geometric representation of cucumbers on the numerical simulation of its cooling
kinetics is studied. It is supposed that the diffusion model with boundary condition of the third kind satisfactorily
describes the cooling, and that the thermo-physical parameters are constant during the process. The geometries used
to represent the cucumber are: infinite cylinder, finite cylinder, and ellipsoid. The diffusion equation was solved
through the finite volume method, with a fully implicit formulation, using cylindrical and generalized coordinates.
The convective heat transfer coefficient and the thermal diffusivity were determined through optimization, using the
inverse method. The best model in the representation of the cucumber�s shape was the ellipsoid, but the time demanded
in its optimization was about 66 times greater than the time for the infinite cylinder.En este trabajo se ha estudiado el efecto de la representación geométrica de los pepinos en la simulación numérica
de su cinética de enfriamiento. Se ha supuesto que el modelo de difusión con la condición de frontera de tercera clase
describe satisfactoriamente el enfriamiento y que los parámetros termofísicos son constantes durante el proceso.
Las geometrías utilizadas para representar el pepino son cilindro infinito, cilindro finito y elipsoide. La ecuación de
difusión se resolvió a través del método de volumen finito, con una formulación totalmente implícita, utilizando
coordenadas cilíndricas y generalizadas. El coeficiente de transferencia de calor por convección y la difusividad térmica
fueron determinados a través de la optimización, utilizando el método inverso. El mejor modelo en la representación
de la forma del pepino fue el elipsoide, pero el tiempo exigido para su optimización fue cerca de 66 veces mayor
que el tiempo para el cilindro infinito
Attached and Planktonic Listeria monocytogenes Global Proteomic Responses and Associated Influence of Strain Genetics and Temperature
Contamination
of industrial and domestic food usage environments
by the attachement of bacterial food-borne pathogen Listeria monocytogenes has public health and economic
implications. Comprehensive proteomics experiments using label-free
liquid chromatography/tandem mass spectrometry were used to compare
the proteomes of two different L. monocytogenes strains (Siliken_1/2c and F2365_4b), which show very different capacities
to attach to surfaces. Growth temperature and strain type were highly
influential on the proteomes in both attached and planktonic cells.
On the basis of the proteomic data, it is highly unlikely that specific
surface proteins play a direct role in adherence to inanimate surfaces.
Instead, strain-dependent responses related to cell envelope polymer
biosynthesis and stress response regulation likely contribute to a
different ability to attach and also to survive external stressors.
Collectively, the divergent proteome-level responses observed define
strain- and growth-temperature-dependent differences relevant to attachment
efficacy, highlight relevant proteins involved in stress protection
in attached cells, and suggest that strain differences and growth
conditions are important in relation to environmental persistence
