Evaluation of energetic and macronutrients intake in the adult Portuguese population

RESUMO - É fundamental conhecer hábitos alimentares e nutricionais de uma população, para poder intervir na promoção da saúde da mesma. Com este estudo epidemiológico transversal representativo da população portuguesa adulta (dados da SPCNA), pretendeu-se conhecer o padrão nutricional de ingestão quer energética quer em macronutrientes. Por entrevista individualizada (domicílio), registaram-se dados sociodemográficos e avaliou-se a ingestão alimentar, por questionário, das 24 h anteriores. Assim, os portugueses ingerem em média: 2.056 kcal/dia, 19,1% de proteínas, 31,3% de gordura, 45,8% de hidratos de carbono e 3,8% de etanol. Estes dados serão válidos para intervenções adequadas na saúde pública portuguesa.ABSTRACT - Gathering knowledge about food and nutritional habits of a population is of the utmost importance since dietary intervention positively impacts health outcomes across the life span. With this transversal epidemiologic study representative of the adult Portuguese population (data from SPCNA), we tried to know the nutritional intake pattern (energy and macronutrients) of the Portuguese population. In an domiciliary individualized interview sociodemographic data were registered and food intake was evaluated by the 24-hour recall method. Portuguese energy intake, is on average, 2056 kcal/day, distributed by 19.1% of protein, 45.8% of carbohydrates and 31.3% of total fat, and 3.8% of ethanol. These data will be important to Portuguese public health interventions.info:eu-repo/semantics/publishedVersio

Burnout among Portuguese healthcare workers during the COVID-19 pandemic

During COVID-19 pandemic, healthcare workers (HCWs) have had high workload and have been exposed to multiple psychosocial stressors. The aim of this study was to evaluate HCWs in terms of the relative contributions of socio-demographic and mental health variables on three burnout dimensions: personal, workrelated, and client-related burnout. Methods: A cross-sectional study was performed using an online questionnaire spread via social networks. A snowball technique supported by health care institutions and professional organizations was applied. Results: A total of 2008 subjects completed the survey. Gender, parental status, marriage status, and salary reduction were found to be significant factors for personal burnout. Health problems and direct contact with infected people were significantly associated with more susceptibility to high personal and work-related burnout. Frontline working positions were associated with all three dimensions. Higher levels of stress and depression in HCWs were significantly associated with increased levels of all burnout dimensions. Higher levels of satisfaction with life and resilience were significantly associated with lower levels of all burnout dimensions. Conclusions: All three burnout dimensions were associated with a specific set of covariates. Consideration of these three dimensions is important when designing future burnout prevention programs for HCWs.info:eu-repo/semantics/publishedVersio

Properties of CrN thin films deposited in plasma-activated ABS by reactive magnetron sputtering

In this work, magnetron sputtered CrNx thin films with nitrogen concentrations ranging from 17 to 30 at.% were deposited on plasma activated ABS. Two sets of thin films were obtained by varying the N-2 flow inside the vacuum chamber (series #1) and the deposition time (series #2). The polymer samples were also subjected to plasma treatment in Ar prior to the CrNx thin films' deposition, in order to enhance the adhesion. The fundamental microstructural, chemical and physical properties, as well as the electrochemical and adhesion behavior of the CrNx thin films, were assessed by SEM, XRD, 3D profilometry, RAMAN, colorimetry, OCP measurements and cross-cut tape test. Main results show that high-quality CrNx films with a low percentage of defects were obtained. The CrNx film sputtered with 3 sccm N-2 for 20 min was considered to possess the most appropriate brightness, color, electrochemical stability and interfacial adhesion to fit the end-user requirements. Magnetron sputtering is thus a promising alternative to the hazardous chrome plating for an effective metallization of ABS.This work was developed within the scope of the project POCI-01-0247-FEDER-003493 co-financed by FEDER through the POCI program and project CICECO-Aveiro Institute of Materials, POCI-01-0145-FEDER-007679 (FCT ref. UID/CTM/50011/2013), financed by national funds through FCT and when appropriate co-financed by FEDER under the PT2020 Partnership Agreement.info:eu-repo/semantics/publishedVersio

Revisão sistematizada da literatura e opinião de peritos

Objective: The 3E (Evidence, Expertise, Exchange) Initiative is a multinational effort of rheumatologists aimed at developing evidence-based recommendations addressing specific questions relevant to clinical practice. The objective of the Portuguese contribution for the 3E Initiative was to develop evidence-based recommendations on how to investigate, follow-up and treat undifferentiated peripheral inflammatory arthritis (UPIA) adapted to local reality and develop additional recommendations considered relevant in the national context. Methods: An international scientific committee from 17 countries selected a set of questions concerning the diagnosis and monitoring of UPIA using a Delphi procedure. Evidence-based answers to each question were sought by a systematic literature search, performed in Medline, Embase, the Cochrane Library and ACR/EULAR 2007-2009 meeting abstracts. Relevant articles were reviewed for quality assessment, data extraction and synthesis. In a national meeting, a panel of 63 Portuguese rheumatologists used the evidence which was gathered to develop recommendations, and filled the gaps in the evidence with their expert opinion. Finally, national recommendations were formulated and agreement among the participants was assessed. Results: A total of 54754 references were identified, of which 267 were systematically reviewed. Thirteen national key recommendations about the investigation, follow-up and treatment of UPIA were formulated. One recommendation addressed differential diagnosis and investigations prior to the established operational diagnosis of UPIA, eight recommendations were related to the diagnostic and prognostic value of clinical and laboratory assessments in established UPIA (history and physical examination, acute phase reactants, serologies, autoantibodies, radiographs, magnetic resonance imaging and ultrasound, genetic markers and synovial biopsy), one recommendation highlighted predictors of persistence (chronicity), one addressed monitoring of clinical disease activity in UPIA, one aimed to find an useful method/score to predict a definitive diagnosis and the last one was related to treatment. Conclusion: Portuguese evidence-based recommendations for the management of UPIA in everyday practice were developed. Their dissemination and implementation in daily clinical practice should help to improve practice uniformity and optimize the management of UPIA patients.publishersversionpublishe

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
