CIOCB: A framework of competences for the Chief Information Officer - Preliminary study

The role of the Chief Information Officer and the expectations about its performance have undergone significant changes in recent years. This transformation was not only driven by the evolution of information technologies and information systems but was also due to its growing importance within organizations. The integration of the information systems manager into the top management team in many organizations also had a direct impact on the profile and competences required to carry out its activities. A review on the set of competences currently required from these managers is therefore required. This research-in-progress paper proposes a framework, named CIOCB, which identifies a broad set of competences needed for the Chief Information Officer.- (undefined

Watchful waiting? Portuguese approach to otitis media with effusion

Vera-Cruz, P., Larroudé, A., Gouveia, N., Mendes, J., & Coelho, P. S. (2021). Watchful waiting? Portuguese approach to otitis media with effusion. Nascer e Crescer: Birth and Grwoth Medical Journal, 30(1), 143-151. https://doi.org/10.25753/BirthGrowthMJ.v30.i3.19192Otitis media with effusion (OME) is an important public health problem. Several clinical practice guidelines for diagnosis and treatment of OME are in place, including from the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS). This study aimed to evaluate the clinical practice of OME diagnosis and treatment among the Otolaryngology medical community working in Portugal. Material and methods: A questionnaire was developed based on AAO-HNS guidelines regarding placement of tympanostomy tubes in children. Each directive was transformed into a question, and further questions were added to improve the characterization of the population and its practices. Results: Answers provided agreed with “recommendations” and “recommendations against” enunciated in the guidelines. The exceptions were recommendations regarding the adoption of measures to prevent water from entering the external ear canal of children with tympanostomy tubes and the use of drugs. Questions asked outside guidelines scope revealed that 96.7% of doctors consider children’s age and 49.1% wait for the end of summer when deciding about surgery for tube placement, 68% recommend bathing in beaches, and 21.9% recommend mineral water treatment.publishersversionpublishe

Effect of Scan Strategies and Use of Support Structures on Surface Quality and Hardness of L-PBF AlSi10Mg Parts

Additive manufacturing allows for a great degree of design freedom and is rapidly becoming a mainstream manufacturing process. However, as in all manufacturing processes, it has its limitations and specificities. Equipping engineers with this knowledge allows for a higher degree of optimization, extracting the most out of this technology. Therefore, a specific part design was devised and created via L-PBF (Laser Powder Bed Fusion) using AlSi10Mg powder. Certain parameters were varied to identify the influence on material density, hardness, roughness, residual stress and microstructures. It was found that on heat treated parts laser pattern strategy is one of the most influential aspects, showing that chessboard and stripes 67° improved outcome; average Ra roughness varied between 8–12 µm, residual stress was higher on vertical surfaces than horizontal surfaces, with the combination of support structures and stripes 67° strategies generating the lowest residual stress (205 MPa on a lateral/vertical face), hardness was non-orientation dependent and larger on samples with chessboard fabrication strategies, while microstructures were composed of α–Al dendrites surrounded by Si particles. The distribution and grain size of the microstructure is dependent on location regarding melt pool and HAZ area. Furthermore, Al–Mg oxides were encountered on the surface, along with pores generating from lack of fusion.The authors would like to acknowledge the Hypermetal Additive Manufacturing for their contribution with some additive manufactured samples and materials, as well as ONA Electro-Erosión Lda. for the use of their electro erosion cutting equipment, used for the separation of certain samples from the build plate.

O contributo de Júlio Henriques para o conhecimento da diversidade vegetal de São Tomé e Príncipe

O arquipélago de São Tomé e Príncipe foi, durante muito tempo, um dos ex-territórios ultramarinos portugueses menos explorado cientificamente. Júlio Henriques, professor da Universidade de Coimbra e director do Jardim Botânico, foi o principal arquitecto da exploração botânica do arquipélago no fim do século XIX. Na extensa rede científica que estabeleceu, participaram naturalistas e amadores, com destaque para A. F. Möller, e cientistas de toda a Europa. São objectivos deste trabalho i) divulgar o contributo de Júlio Henriques para o conhecimento da flora de S. Tomé e Príncipe através da análise dos trabalhos publicados, na sua maioria, no Boletim da Sociedade Broteriana e ii) evidenciar a actualidade e pertinência desses trabalhos e das colecções botânicas produzidas para a investigação actual.São Tomé and Príncipe was one of the Portuguese overseas ex-territories less scientifically explored for many years. Júlio Henriques, professor at the University of Coimbra and director of its Botanical Garden, was by the end of the XIXth century, the mentor of the botanical exploration of the archipelago. Within the broad scientific network he established amateurs and naturalists alike participated, with emphasis to A. F. Möller, and scientists all over Europe. The goals of this article are to: i) appraise Júlio Henriques’ contribution to the knowledge of São Tomé and Príncipe’s flora, through the analysis of his published work, mainly in the Boletim da Sociedade Broteriana and ii) highlight the pertinence and relevance of these works and biological collections to current research

Obesity, acute kidney injury and mortality in patients with sepsis: a cohort analysis

Although the prognostic effect of obesity has been studied in critically ill patients its impact on outcomes of septic patients and its role as a risk factor for acute kidney injury (AKI) is not consensual. We aimed to analyze the impact of obesity on the occurrence of AKI and on in-hospital mortality in a cohort of critically ill septic patients. This study is retrospective including 456 adult patients with sepsis admitted to the Division of Intensive Medicine of the Centro Hospitalar Lisboa Norte (Lisbon, Portugal) between January 2008 and December 2014. Obesity was defined as a body mass index of 30 kg/m2 or higher. The Kidney Disease Improving Global Outcomes classification was used to diagnose and classify patients developing AKI. AKI occurred in 87.5% of patients (19.5% with stage 1, 22.6% with stage 2 and 45.4% with stage 3). Obese patients developed AKI more frequently than non-obese patients (92.8% versus 85.5%, p = .035; unadjusted OR 2.2 (95% CI: 1.04-4.6), p = .039; adjusted OR 2.31 (95% CI: 1.07-5.02), p = .034). The percentage of obese patients, however, did not differ between AKI stages (stage 1, 25.1%; stage 2, 28.6%; stage 3, 15.4%; p = .145). There was no association between obesity and mortality (p = .739). Of note, when comparing AKI patients with or without obesity in terms of in-hospital mortality there were also no significant differences between those groups (38.4% versus 38.4%, p = .998). Obesity was associated with the occurrence of AKI in critically ill patients with sepsis; however, it was not associated with in-hospital mortality.info:eu-repo/semantics/publishedVersio

Publisher Copyright: © The Author(s) 2022.Objective: To identify the core components of digital behaviour change interventions for weight loss maintenance targeting physical activity, in terms of: (i) behaviour change techniques, (ii) mechanisms of action, (iii) modes of delivery, (iv) dose and (v) tailoring/personalization. In addition, the links between these components were investigated. Methods: A literature search was performed in five electronic databases: PubMed, Embase, CINHAL, PsycINFO and Web of Science. Two reviewers independently screened the identified articles and extracted data related with the study characteristics and behaviour change techniques, mechanism of action, mode of delivery, dose, and tailoring, using standardized classifications whenever available (e.g. behaviour change techniques taxonomy). Results: Seventeen articles reporting 11 original studies were selected. Two studies were protocols, 9 studies presented results for weight change and all but one showed no significant differences between the intervention and control groups. Eight studies (73%) provided adequate information on behaviour change techniques. Five studies (45%) provided partial information about how the behaviour change techniques were linked to mechanisms of action, and only one study (0.9%) described these links for all the techniques. Around half of the studies reported the modes through which behaviour change techniques were delivered. Descriptions of dose were present in most studies, but with minimal information. The use of tailoring or personalization approaches was mentioned in eight studies (73%), but descriptions of what was tailored and how were minimal. Conclusions: The compilation of information regarding intervention components was difficult due to the lack of information and systematization in reporting across papers. This is particularly true for the reporting of the links between behaviour change techniques and the other core intervention components. This information is crucial to help us understand in the context of behaviour change interventions what works or does not work, how it works and why.publishersversionpublishe

Algorithms for automated diagnosis of cardiovascular diseases based on ECG data: A comprehensive systematic review

The prevalence of cardiovascular diseases is increasing around the world. However, the technology is evolving and can be monitored with low-cost sensors anywhere at any time. This subject is being researched, and different methods can automatically identify these diseases, helping patients and healthcare professionals with the treatments. This paper presents a systematic review of disease identification, classification, and recognition with ECG sensors. The review was focused on studies published between 2017 and 2022 in different scientific databases, including PubMed Central, Springer, Elsevier, Multidisciplinary Digital Publishing Institute (MDPI), IEEE Xplore, and Frontiers. It results in the quantitative and qualitative analysis of 103 scientific papers. The study demonstrated that different datasets are available online with data related to various diseases. Several ML/DP-based models were identified in the research, where Convolutional Neural Network and Support Vector Machine were the most applied algorithms. This review can allow us to identify the techniques that can be used in a system that promotes the patient’s autonomy.N/
