Lives on hold: the experiences of asylum seekers in Moria refugee camp

Of the hundreds of thousands of people that formed the huge migratory flow of the so-called ‘refugee crisis’, many are currently living in refugee camps, at times without basic conditions. This research aims to describe the lived experience of these people and amplify their voices. In order to pursue this goal, we conducted 15 semi-structured interviews with asylum seekers accomodated in the Kara Tepe refugee camp but who had also had experience of life in Moria refugee camp (both camps are in Greece). We complemented these data with participant observations carried out in the Kara Tepe refugee camp and some visits at the surroundings of Moria camp. Our results highlight a much worse experience of asylum seekers in Moria refugee camp if compared to asylum seekers’ experience in Kara Tepe, with reports of overcrowding, hunger, lack of hygiene, poor healthcare, insecurity and violence. The psychological impact of the high number of adversities affecting people living under these circunstances also stood out, with evidence of distress experienced. We conclude by discussing the implications of our findings in terms of policy change.info:eu-repo/semantics/publishedVersio

Immune-evasion strategies of mycobacteria and their implications for the protective immune response

Mycobacteria are intracellular pathogens that have macrophages as their main host cells. However, macrophages are also the primary line of defense against invading microorganisms. To survive in the intracellular compartment, virulent mycobacteria have developed several strategies to modulate the activation and the effector functions of macrophages. Despite this, antigen-specific T cells develop during infection. While T cell responses are critical for protection they can also contribute to the success of mycobacteria as human pathogens, as immunopathology associated with these responses facilitates transmission. Here, we provide a brief overview of different immune-evasion strategies of mycobacteria and their impact on the protective immune response. This understanding will further our knowledge in host-pathogen interactions and may provide critical insights for the development of novel host-specific therapies.Our work is funded by the project NORTE-01-0145-FEDER-000013, supported by the Northern Portugal Regional Operational Programme (NORTE 2020), under the Portugal 2020 Partnership Agreement, through the European Regional Development Fund (FEDER); Infect-ERA grant BU_SPONT_HEAL; and the Fundação para a Ciência e Tecnologia (FCT) through the FCT investigator grant IF/01390/2014 to E.T. and the postdoctoral grant SFRH/BPD/112903/2015 to A.G.F.info:eu-repo/semantics/publishedVersio

Increased CD3+, CD8+, or FoxP3+ T lymphocyte infiltrations are associated with the pathogenesis of colorectal cancer but not with the overall survival of patients

Tumor-infiltrating lymphocytes include heterogeneous populations of T lymphocytes that play crucial roles in the tumor immune response; importantly, their presence in the tumor tissue may predict clinical outcomes. Therefore, we herein studied the prognostic significance of the presence and location of CD3+, CD8+, and FoxP3+ T lymphocytes in colorectal cancer samples. In the intratumor analysis, our data did not reveal any association between lymphocyte infiltrations with clinical or pathological data. However, in the tumor margins, we found that the presence of high infiltrations of CD3+, CD8+, or FoxP3+ T lymphocytes were associated with TNM stages I-II (p = 0.021, p = 0.022, and p = 0.012, respectively) and absence of lymph node metastases (p = 0.010, p = 0.003, and p = 0.004, respectively). Despite these associations with good prognostic indicators, we were not able to find any statistically significant alterations in the overall survival of the patients, even though high infiltrations of FoxP3+ T lymphocytes in the tumor margins resulted in an increased overall survival of 14 months. Taken together, these data show that the presence of CD3+, CD8+, or FoxP3+T lymphocyte infiltrates in the tumor margins are associated with the pathogenesis of CRC, but only high Foxp3+ T lymphocyte infiltrations in the tumor invasive margins are inclined to indicate favorable prognosis.This work was supported by National funds through the Foundation for Science and Technology (FCT)—projects PTDC/MED-ONC/28658/2017, UIDB/50026/2020, and UIDP/50026/2020; and by the Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF) projects NORTE-01-0145-FEDER-000013 and NORTE-01-0145-FEDER-000023.

Conhecimento de geometria de estudantes da licenciatura em Educação Básica

Este estudo quantitativo tem como objetivo avaliar o desenvolvimento do conhecimento de geometria de mais de duas centenas de estudantes do ensino superior a frequentar o curso de Educação Básica em três ESE. 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.ABSTRACT: This quantitative study aims to assess the development of geometry knowledge of over two hundred students attending Basic Education course in three Schools of Education. Through a test with 21 questions, handed over before and after training in Geometry, students are assessed in a set of categories. The results reveal that although students demonstrate knowledge of elementary concepts at the outset, with percentages of success above 70%, and evolution at the three schools, with an average increase of 5%, also reveal critical aspects related to basic concepts covered in the test

HER Family Receptors are Important Theranostic Biomarkers for Cervical Cancer: Blocking Glucose Metabolism Enhances the Therapeutic Effect of HER Inhibitors

Persistent HPV infection alone is not sufficient for cervical cancer development, which requires additional molecular alterations for tumor progression and metastasis ultimately leading to a lethal disease. In this study, we performed a comprehensive analysis of HER family receptor alterations in cervical adenocarcinoma. We detected overexpression of HER protein, mainly HER2, which was an independent prognostic marker for these patients. By using in vitro and in vivo approaches, we provided evidence that HER inhibitors, allitinib and lapatinib, were effective in reducing cervical cancer aggressiveness. Furthermore, combination of these drugs with glucose uptake blockers could overcome the putative HIF1-a-mediated resistance to HER-targeted therapies. Thus, we propose that the use of HER inhibitors in association with glycolysis blockers can be a potentially effective treatment option for HER-positive cervical cancer patients.FINEP (MCTI/FINEP/MS/SCTIE/DECIT-BIOPLAT (1302/13), Brazil and co-funded by the project “ON.2 SR&TD Integrated Program (NORTE-07-0124-FEDER-000017)” co-funded by Programa Operacional Regional do Norte (ON.2- O Novo Norte), Quadro de Referência Estratégico Nacional (QREN), through Fundo Europeu de Desenvolvimento Regional (FEDER).

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records.

Práticas artísticas no ensino básico e secundário

A educação pela arte faz-se através dos seus materiais, da sua operação, da transformação das matérias em ideias novas, em novas coisas. No seu sucesso está implicada uma literacia, uma capacidade interpretativa, ou crítica, sobre a semiosfera cada vez mais povoada, saturada de mensagens parasitárias. A educação implica uma leitura do mundo (Paulo Freire), que se projeta na interpretação de todas as camadas de expressão contemporânea, muitas vezes massificada, por vezes ainda identitária e significativa. Fala-se aqui de valorizar a identidade, exercer a pedagogia da diferença através de uma capacidade problematizadora. No seu contexto, podem exercer-se pedagogias que exploram a visão crítica do artista em interação com a escola, o artista em residência, no movimento A/ R/ Tography. Ou também exercer-se uma pedagogia triangular, centrando a arte, o contexto, a produção e a sua leitura como uma metodologia (Ana Mae Barbosa). O contexto contemporâneo é pós digital, os conteúdos não pesam nos suportes, e transmitem-se por “dentes azuis” ou redes com muitos Gs (G de Geração sem peso que sucede ao peso da aceleração gravítica). Neste campo pode delinear-se uma metodologia que alicerça o projeto ancorado nos estudos críticos sobre Cultura Visual (Fernando Hernández). Digamos que as práticas pedagógicas se cruzam em diversas direções, tacteando eficácias, expressões, capacidades, inovação. O contexto é cada vez mais voraz: a pele da cultura gosta de massagens (Kerkhove; McLuhan). A Matéria-Prima de que se fala nesta revista é aquela que devolve ao seu lugar um ponto crítico da pós modernidade: o do significante. Os sintagmas são sempre processos, e neles se formam as subjectividades, ou seja, as identidades: no desenrolar do ser, onde se produz verdadeiramente o sentido, bem junto do aqui-e-agora onde está a Matéria-Prima (Foucault).info:eu-repo/semantics/publishedVersio

Mammals in Portugal: a data set of terrestrial, volant, and marine mammal occurrences in Portugal

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt
