Autoeficácia empreendedora no ensino superior: o caso dos estudantes do Instituto Politécnico de Coimbra

O empreendedorismo assume nos dias de hoje uma importância inquestionável na dinamização económica das sociedades, agregando em torno do tema políticos, académicos e empresários. Identificado como processo dinâmico de mudança, de identificação e criação de novas oportunidades, o empreendedorismo assume-se na atualidade como elemento fundamental no desenvolvimento económico dos países, sendo encarado como um agente determinante de inovação, competitividade e crescimento. Pretende-se com este estudo exploratório analisar a intenção empreendedora dos estudantes de quatro escolas do Instituto Politécnico de Coimbra, relacionando-a com a autoeficácia empreendedora e a autoeficácia académica, e determinar quais os fatores que a influenciam. Para o efeito foram distribuídos questionários a uma amostra de 290 alunos de quatro escolas do IPC, constituída por 114 (39.3%) homens e 176 mulheres (60.7%). Os resultados obtidos demonstram que o desenvolvimento de expetativas elevadas de autoeficácia académica e de autoeficácia empreendedora estão fortemente associadas à vontade de desenvolvimento de um projeto empreendedor e ao sentimento de que se é capaz de realizar os passos necessários para o conseguir. Conclui-se também que os estudantes que mais acreditam nas suas capacidades académicas e nas suas capacidades empreendedoras são também aqueles que mais valorizam a importância de uma estrutura de apoio do IPC à criação de empresas. Por fim, este estudo sugere que as estruturas do IPC dirigidas ao fomento de atitudes empreendedoras devem focar a sua atenção nos estudantes com uma autoeficácia académica e uma autoeficácia empreendedora elevadas, ou seja, aqueles que declaram uma intenção mais forte de serem empreendedores, e podem promover o espírito empreendedor realizando ações capazes de incrementarem as expetativas de autoeficácia académica e empreendedora dos seus estudantes

Publisher Copyright: © 2023 by the authors.Anaplastic thyroid carcinoma (ATC) is the most lethal subtype of thyroid cancer, with high invasive and metastatic potential, not responding to conventional treatments. Its aggressiveness may be influenced by macrophages, which are abundant cells in the tumor microenvironment. To investigate the role of macrophages in ATC aggressiveness, indirect co-cultures were established between ATC cell lines and THP-1-derived macrophages. Macrophages significantly increased both the migration and invasion of T235 cells (p < 0.01; p < 0.01), contrasting with a decrease in C3948 (p < 0.001; p < 0.05), with mild effects in T238 migration (p < 0.01) and C643 invasion (p < 0.05). Flow cytometry showed upregulation of CD80 (pro-inflammatory, anti-tumoral) and downregulation of CD163 (anti-inflammatory, pro-tumoral) in macrophages from co-culture with T235 (p < 0.05) and C3948 (p < 0.05), respectively. Accordingly, we found an upregulation of secreted pro-inflammatory mediators (e.g., GM-CSF, IL-1α; p < 0.05) in C3948–macrophage co-cultures. Proteomic analysis showed the upregulation of SPRY4, an inhibitor of the MAPK pathway, in C3948 cells from co-culture. SPRY4 silencing promoted cancer cell invasion, reverting the reduced invasion of C3948 caused by macrophages. Our findings support that macrophages play a role in ATC cell aggressiveness. SPRY4 is a possible modulator of macrophage–ATC cell communication, with a tumor suppressor role relevant for therapeutic purposes.publishersversionpublishe

Clinical and molecular characterisation of metastatic papillary thyroid cancer according to radioiodine therapy outcomes

Publisher Copyright: © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Purpose: Radioiodine (RAI) therapy remains the gold-standard approach for distant metastatic differentiated thyroid cancer (TC). The main objective of our work was to identify the clinical and molecular markers that may help to predict RAI avidity and RAI therapy response of metastatic lesions in a cohort of papillary thyroid cancer (PTC) patients. Methods: We performed a retrospective analysis of 122 PTC patients submitted to RAI therapy due to distant metastatic disease. We also analysed, through next-generation sequencing, a custom panel of 78 genes and rearrangements, in a smaller cohort of 31 metastatic PTC, with complete follow-up, available RAI therapy data, and existing tumour sample at our centre. Results: The most frequent outcome after RAI therapy was progression of disease in 59.0% of cases (n = 71), with median estimate progression-free survival of 30 months. RAI avidity was associated with PTC subtype, age and stimulated thyroglobulin at first RAI therapy for metastatic disease. The most frequently altered genes in the cohort of 31 PTC patients’ primary tumours were RAS isoforms (54.8%) and TERT promoter (TERTp) (51.6%). The presence of BRAF p.V600E or RET/PTC alterations was associated with lower avidity (p = 0.012). TERTp mutations were not associated with avidity (p = 1.000) but portended a tendency for a higher rate of progression (p = 0.063); similar results were obtained when RAS and TERTp mutations coexisted (p = 1.000 and p = 0.073, respectively). Conclusions: Early identification of molecular markers in primary tumours may help to predict RAI therapy avidity, the response of metastatic lesions and to select the patients that may benefit the most from other systemic therapies.publishersversionepub_ahead_of_prin

Palliative patients in the portuguese public hospitals

Introdução: A identificação e referenciação precoce dos doentes com necessidades paliativas é fundamental para que em tempo útil possam usufruir da efetividade da intervenção precoce de cuidados paliativos. Referenciar para cuidados Paliativos é um importante, crescente e complexo desafio e processo para a prática dos profissionais de saúde, nomeadamente para os médicos. A falta de informação e formação podem impedir a proatividade no processo de referenciação precoce. Atualmente, existem já alguns instrumentos multidimensionais que ajudam a identificar a população com necessidades paliativas. A pergunta surpresa, validada para Portugal, “Ficaria surpreendido se este doente morresse durante o próximo ano?” é uma ferramenta importante, útil e fiável para esta identificação. Objetivo: determinar a prevalência de doentes adultos com necessidades paliativas internados em hospitais públicos. Como objetivos secundários, determinar o número de doentes referenciados para cuidados paliativos e identificar os motivos de não referenciação destes doentes. Materiais e Métodos: Estudo analítico, observacional e transversal, realizado no primeiro trimestre de 2015 em 11 hospitais do SNS. O instrumento de colheita de dados consistiu num questionário com caracterização demográfica e clinica, a pergunta surpresa relativa a 1 ano, 6 e 1 mês e, 15 dias, e 19 possíveis motivos para não referenciação dos doentes. Os dados recolhidos forma analisados com recurso à estatística descritiva e analítica, considerando-se significância estatística se p<0.05. Resultados: De um total de 1273 doentes, 51.4% eram doentes com necessidades paliativas, a maioria proveniente dos serviços de oncologia (79.3%) e medicina (62.3%), e maioritariamente com doença oncológica (67.2%). Apenas estavam referenciados 6.8 a 9.9% dos doentes, maioritariamente oncológicos (15.1%) ou com 15 ou menos dias de vida (9.8%). Os cinco principais motivos para não referenciação foram: ainda estar a fazer tratamento ativo (61.5%), “ainda se poder fazer alguma coisa do ponto de vista curativo” (40.9%), o doente estar controlado a nível sintomático (33.2%), ainda não estar a morrer (27.6%) e os cuidados paliativos não serem uma mais-valia para o doente (15.4%). Conclusão: Elevada prevalência de doentes e baixa taxa de referenciação. É necessária e imperiosa a formação e capacitação dos profissionais de saúde para uma adequada identificação e referenciação e tempo útil dos doentes com necessidades paliativas.Early identification and referral of patients with palliative needs is essential so they can benefit from the effectiveness of early intervention of palliative care. Referral for palliative care is an important, growing and complex challenge and process for the practice of health professionals, particularly for physicians. Lack of information and training may prevent proactivity in the process of early refer Currently, some multidimensional instruments help to identify the population with palliative needs. The surprise question, validated for Portugal, “Would you be surprised if this patient died during the next year?” is an important, useful and reliable tool for this identification.Aim: to determine the prevalence of adult patients with palliative needs hospitalized in public hospitals; to determine who were referenced for palliative care and to identify the reasons for non-referral of these patients.Material and Methods: an analytical, observational and cross-sectional study was performed in the first quarter of 2015 in 11 hospitals of the Portuguese Health System. The data collection instrument consisted of a questionnaire with demographic and clinical characterization, the surprise question regarding 1 year, 6 and 1 month and, 15 days, and 19 possible reasons for non-referral of patients. The collected data were analyzed using descriptive and analytical statistics, considering statistical significance if p <0.05.Results: From a total of 1273 patients, 51.4% were patients with palliative needs, the majority coming from the oncology (79.3%) and medicine services (62.3%), and mainly with oncological disease (67.2%). Only 6.8 to 9.9% of the patients were referred, mainly oncological (15.1%) or with 15 days or less of life (9.8%). The five main reasons for non-referral were: still being under active treatment (61.5%), “still able to do something from a curative point of view” (40.9%), the patient being symptomatically controlled (33.2%), not considered to be actively dying (27.6%) and not being an added value to the patient (15.4%).Conclusions: High prevalence of patients with palliative care need, low referral rate. The training and qualification of health professionals is necessary and imperative for an adequate identification and referral in a useful time of patients with palliative needs

Nucleolin Overexpression Predicts Patient Prognosis While Providing a Framework for Targeted Therapeutic Intervention in Lung Cancer

Notwithstanding the advances in the treatment of lung cancer with immune checkpoint inhibitors, the high percentage of non-responders supports the development of novel anticancer treatments. Herein, the expression of the onco-target nucleolin in patient-derived pulmonary carcinomas was characterized, along with the assessment of its potential as a therapeutic target. The clinical prognostic value of nucleolin for human pulmonary carcinomas was evaluated through data mining from the Cancer Genome Atlas project and immunohistochemical detection in human samples. Cell surface expression of nucleolin was evaluated by flow cytometry and subcellular fraction Western blotting in lung cancer cell lines. Nucleolin mRNA overexpression correlated with poor overall survival of lung adenocarcinoma cancer patients and further predicted the disease progression of both lung adenocarcinoma and squamous carcinoma. Furthermore, a third of the cases presented extra-nuclear expression, contrasting with the nucleolar pattern in non-malignant tissues. A two- to twelve-fold improvement in cytotoxicity, subsequent to internalization into the lung cancer cell lines of doxorubicin-loaded liposomes functionalized by the nucleolin-binding F3 peptide, was correlated with the nucleolin cell surface levels and the corresponding extent of cell binding. Overall, the results suggested nucleolin overexpression as a poor prognosis predictor and thus a target for therapeutic intervention in lung cancer

Primary adrenal insufficiency in adult population: a Portuguese multicentre study by the Adrenal Tumours Study Group

INTRODUCTION: Primary adrenal insufficiency (PAI) is a rare but severe and potentially life-threatening condition. No previous studies have characterized Portuguese patients with PAI. AIMS: To characterize the clinical presentation, diagnostic workup, treatment and follow-up of Portuguese patients with confirmed PAI. METHODS: This multicentre retrospective study examined PAI patients in 12 Portuguese hospitals. RESULTS: We investigated 278 patients with PAI (55.8% were females), with a mean age of 33.6±19.3 years at diagnosis. The most frequent presenting clinical features were asthenia (60.1%), mucocutaneous hyperpigmentation (55.0%) and weight loss (43.2%); 29.1% of the patients presented with adrenal crisis. Diagnosis was established by high plasma ACTH and low serum cortisol in most patients (43.9%). The most common etiology of PAI was autoimmune adrenalitis (61.0%). There were 38 idiopathic cases. Autoimmune comorbidities were found in 70% of the patients, the most frequent being autoimmune thyroiditis (60.7%) and type 1 diabetes mellitus (17.3%). Seventy-nine percent were treated with hydrocortisone (mean dose 26.3±8.3 mg/day) mostly in three (57.5%) or two (37.4%) daily doses. The remaining patients were treated with prednisolone (10.1%), dexamethasone (6.2%) and methylprednisolone (0.7%); 66.2% were also on fludrocortisone (median dose of 100 g/day). Since diagnosis, 33.5% of patients were hospitalized for disease decompensation. In the last appointment, 17.2% of patients had complaints (7.6% asthenia and 6.5% depression) and 9.7% had electrolyte disturbances. CONCLUSION: This is the first multicentre Portuguese study regarding PAI. The results emphasize the need for standardization in diagnostic tests and aetiological investigation and provide a framework for improving treatment.info:eu-repo/semantics/publishedVersio

Useful ultrasonographic parameters to predict difficult laryngoscopy and difficult tracheal intubation-a systematic review and meta-analysis

The Supplementary Material for this article can be found online at: https://www.frontiersin.org/articles/10.3389/fmed.2021.671658/full#supplementary-materialUnexpected difficult airway management can cause significant morbidity and mortality in patients admitted for elective procedures. Ultrasonography is a promising tool for perioperative airway assessment, nevertheless it is still unclear which sonographic parameters are useful predictors of difficult laryngoscopy and tracheal intubation. To determine the ultrasonographic predictors of a difficult airway that could be applied for routine practice, a systematic review and meta-analysis was conducted. Literature search was performed on PubMED, Web of Science and Embase using the selected keywords. Human primary studies, published in English with the use of ultrasonography to prediction of difficult laryngoscopy or tracheal intubation were included. A total of 19 articles (4,570 patients) were analyzed for the systematic review and 12 articles (1,141 patients) for the meta-analysis. Standardized mean differences between easy and difficult laryngoscopy groups were calculated and the parameter effect size quantified. A PRISMA methodology was used and the critical appraisal tool from Joanna Briggs Institute was applied. Twenty-six sonographic parameters were studied. The overall effect of the distance from skin to hyoid bone (p = 0.02); skin to epiglottis (p = 0.02); skin to the anterior commissure of vocal cords (p = 0.02), pre-epiglottis space to distance between epiglottis and midpoint between vocal cords (p = 0.01), hyomental distance in neutral (p < 0.0001), and extended (p = 0.0002) positions and ratio of hyomental distance in neutral to extended (p = 0.001) was significant. This study shows that hyomental distance in the neutral position is the most reliable parameter for pre-operative airway ultrasound assessment. The main limitations of the study are the small sample size, heterogeneity of studies, and absence of a standardized ultrasonographic evaluation method [Registered at International prospective register of systematic reviews (PROSPERO): number 167931].This work has been funded by National funds, through the Foundation for Science and Technology (FCT)-project UIDB/50026/2020 and UIDP/50026/2020; and by the projects NORTE-01-0145-FEDER-000013 and NORTE-01-0145-FEDER-000023, supported by Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF)

Measuring adherence to inhaled control medication in patients with asthma: Comparison among an asthma app, patient self‐report and physician assessment

Background Previous studies have demonstrated the feasibility of using an asthma app to support medication management and adherence but failed to compare with other measures currently used in clinical practice. However, in a clinical setting, any additional adherence measurement must be evaluated in the context of both the patient and physician perspectives so that it can also help improve the process of shared decision making. Thus, we aimed to compare different measures of adherence to asthma control inhalers in clinical practice, namely through an app, patient self-report and physician assessment. Methods This study is a secondary analysis of three prospective multicentre observational studies with patients (≥13 years old) with persistent asthma recruited from 61 primary and secondary care centres in Portugal. Patients were invited to use the InspirerMundi app and register their inhaled medication. Adherence was measured by the app as the number of doses taken divided by the number of doses scheduled each day and two time points were considered for analysis: 1-week and 1-month. At baseline, patients and physicians independently assessed adherence to asthma control inhalers during the previous week using a Visual Analogue Scale (VAS 0–100). Results A total of 193 patients (72% female; median [P25–P75] age 28 [19–41] years old) were included in the analysis. Adherence measured by the app was lower (1 week: 31 [0–71]%; 1 month: 18 [0–48]%) than patient self-report (80 [60–95]) and physician assessment (82 [51–94]) (p 0.05). There was a moderate correlation between patient self-report and physician assessment (ρ = 0.596, p < 0.001). Conclusions Adherence measured by the app was lower than that reported by the patient or the physician. This was expected as objective measurements are commonly lower than subjective evaluations, which tend to overestimate adherence. Nevertheless, the low adherence measured by the app may also be influenced by the use of the app itself and this needs to be considered in future studies.info:eu-repo/semantics/publishedVersio

Influenza severe cases in hospitals, between 2014 and 2016 in Portugal

Rede Portuguesa de Laboratórios para o Diagnóstico da GripeBackground: Since 2009, the Portuguese Laboratory Network (PLNID) for Influenza Diagnosis has integrated 15 Laboratories in mainland and Atlantic Islands of Azores and Madeira. This PLNID added an important contribute to the National Influenza Surveillance Program regarding severe and hospitalized influenza cases. The present study aims to describe influenza viruses detected in influenza like illness (ILI) cases: outpatients (Outp), hospitalized (Hosp), and intensive care units (ICU), between 2014 and 2016. Methods: The PLNID performs influenza virus diagnosis by biomolecular methodologies. Weekly reports to the National Influenza Reference Laboratory ILI cases tested for influenza. Reports include data on detecting viruses, hospital assistance, antiviral therapeutics, and information on death outcome. Were reported during two winter seasons 8059 ILI cases,being 3560 cases in 2014/15 (1024 in Outp, 1750 Hosp, and 606 in ICU) and 4499 cases in 2015/2016 (1933 in Outp, 1826 Hosp, and 740 in ICU). Results: The higher percentage of influenza positive cases were detected in Outp in both seasons, 18% during 2014/15 and 20% in 2015/16. In 2014/15,influenza cases were more frequent in individuals older than 65 years old and these required more hospitalizations,even in ICU. In 2015/16,the influenza cases were mainly detected in individuals between 15-64 years old. A higher proportion of influenza positive cases with hospitalization in ICU were observed in adults between 45-64 years old.During the study period,the predominant circulating influenza viruses were different in the two seasons: influenza B and A(H3) co-circulated in 2014/15,and influenza A(H1)pdm09 was predominant during 2015/16. Even when influenza A is notthe dominant virus, A(H3) and A(H1)pdm09 subtypes correlate with higher detection rate in hospitalized cases (Hosp and UCI), with higher frequencies in adults older than 45. Influenza B,detected in higher proportion in outpatients, was frequently relatedwith influenza cases in younger age groups: 0-4 and 5-14 years old. Conclusions: This study highlights the correlation of theinfluenza virus type/subtype that circulates in each season with the possible need for hospitalization and intensive care in special groups of the population. Circulation of influenza A subtypes can cause more frequentdisease in individuals older than 45, with need of hospitalization including intensive care. On the other hand, influenza B is more frequently associated with less severe cases and with infection in children and younger adults. Influenza B circulation might predict lower number of hospitalizations.The identification of influenza type in circulation,byPLNID ineach season, could guide action planning measures in population health care.info:eu-repo/semantics/publishedVersio
