MLaaS: Machine Learning as a Service

The demand for knowledge extraction has been increasing. With the growing amount of data being generated by global data sources (e.g., social media and mobile apps) and the popularization of context-specific data (e.g., the Internet of Things), companies and researchers need to connect all these data and extract valuable information. Machine learning has been gaining much attention in data mining, leveraging the birth of new solutions. This paper proposes an architecture to create a flexible and scalable machine learning as a service. An open source solution was implemented and presented. As a case study, a forecast of electricity demand was generated using real-world sensor and weather data by running different algorithms at the same time

Prickly Connections: Sociodemographic Factors Shaping Attitudes, Perception and Biological Knowledge about the European Hedgehog

The modern lifestyle of humans is leading to a limited exposure to nature. While several wild species are adapting and thriving in anthropic environments, natural history knowledge is declining, and positive attitudes and behaviours towards nature are facing challenges. Because anticipating attitudes and engendering broad-based support for nature-related measures requires a good grasp of social contexts, we set out to evaluate the sociodemographic factors driving the perception, attitudes towards, and natural history knowledge of a keystone species—the European hedgehog. In 2022, we conducted a questionnaire answered by 324 Portuguese adults. We found generally positive feelings and attitudes towards this species. A higher degree of academic qualifications and previous personal experience with the species seem to play a role in (i) people’s perception about human impacts on hedgehogs and (ii) positive attitudes, especially during encounters where the animals were in difficulty. Despite this, the extent of natural history knowledge was low overall, and the study population was self-aware of this. Our insights underline the need to tailor educational programmes if we are to encourage people to re-establish meaningful connections with nature, to foster social support for biodiversity stewardship, and to implement the One Health approach in a way that resonates with distinct social groups.We thank Clarisse Rodrigues from Centro de Recuperação e Interpretação do Ouriço (CRIDO) and all the staff at Centro de Recuperação de Animais Selvagens da Universidade de Trás-os-Montes e Alto Douro (CRAS-HVUTAD).

Anti-inflammatory activity of Blutaparon portulacoides ethanolic extract against the inflammatory reaction induced by Bothrops jararacussu venom and isolated myotoxins BthTX-I and II

This article reports the anti-inflammatory effect of Blutaparon portulacoides (B. portulacoides), specifically the ethanolic extract of its aerial parts, on the edema formation and leukocyte influx caused by Bothrops jararacussu (B. jararacussu) snake venom and Bothropstoxin-I and II (BthTX-I and II) isolated from this venom as an alternative treatment for Bothrops snakebites. The anti-inflammatory effect of B. portulacoides ethanolic extract was compared with an animal group pretreated with dexamethasone. B. portulacoides ethanolic extract significantly inhibited paw edema induced by B. jararacussu venom and by BthTX-I and II. Also, results demonstrated that the extract caused a reduction of the leukocyte influx induced by BthTX-I. However, the extract was not capable of inhibiting the leukocyte influx induced by the venom and by BthTX-II. In conclusion, these results suggest that the ethanolic extract of this plant possess components able to inhibit or inactivate toxins present in B. jararacussu venom, including its myotoxins, responsible for the edema formation. However, the leukocyte migration caused by the venom and BthTX-II was not inhibited by the plant, probably due to the different mechanisms involved in the edema formation and leukocyte influx. This is the first report of B. portulacoides extract as anti-inflammatory against snake venoms and isolated toxins

Effect of superior blepharoplasty on tear film: objective evaluation with the Keratograph 5M - a pilot study

PURPOSE: To evaluate the effect of superior blepharoplasty on the tear film using the corneal topographer Keratograph 5M. METHODS: A prospective study was performed of 27 eyes of 14 patients with superior dermatochalasis who underwent superior blepharoplasty between May and June 2016. Conservative upper eyelid blepharoplasty was performed by an en bloc resection of anterior lamellar tissue that included skin, subcutaneous tissue, and the orbicularis oculi muscle. All the eyes were imaged using the noninvasive tear breakup time tools of the Keratograph 5M. The following parameters were recorded in each patient before and 6 weeks after surgery: first noninvasive Keratograph 5M tear breakup time (the time at which the first breakup of tears occurs) and average noninvasive Keratograph 5M tear breakup time (the average time of all breakup incidents). The exclusion criteria were ophthalmological pathology, previous eyelid surgery, use of eye drops, systemic pathology, and medication that interferes with lacrimal tears. RESULTS: The mean age of the patients was 65.1 years (range, 51-84); 86% were female. Student's t-test was used to compare the values of first and average noninvasive Keratograph 5M tear breakup times before and after surgery. The values for first noninvasive Keratograph 5M tear breakup time evaluated before and after surgery were not significantly different (9.04 and 8.71, respectively; p=0.926). The values for average noninvasive Keratograph 5M tear breakup time evaluated before and after surgery were also not significantly different (13.01 seconds and 13.14 seconds, respectively; p=0.835). CONCLUSIONS: The results of this pilot study suggest that upper blepharoplasty does not affect tear breakup time according to the objective evaluation of breakup time with the Keratograph 5M.info:eu-repo/semantics/publishedVersio

Impact of montelukast as add on treatment to the novel coronavirus pneumonia (COVID-19): protocol for an investigator-initiated open labeled randomized controlled pragmatic trial

Background: Montelukast, a safe drug widely use in asthmatic patients, may be an adjuvant in the treatment of Covid-19, either by improving lung injury and inflammation, or by acting as an anti-viral drug. We aim to assess the efficacy and safety of montelukast as add-on treatment in patients with Covid-19. Methods: We propose a randomized, controlled, parallel, open-label trial involving 160 hospitalized adult patients with confirmed Covid-19. Patients will be randomly assigned in a 1:1 ratio to receive either montelukast 10 mg, once a day for 14 days, in addition to standard of care (SoC), or SoC alone. SoC will follow the best practice for treating these patients, according to updated recommendations. The primary outcome is time to recovery. Participants will be assessed using diary cards to capture data on treatment-related improvements in an 8-point ordinal scale. Secondary endpoints will include changes in respiratory and inflammatory parameters, and adverse events. This phase IV clinical trial will take place at the University Hospital of São João, Porto. EudraCT number: 2020-001747-21. Results: This study intends to generate scientific evidence on efficacy and safety of montelukast as add-on treatment in Covid-19. The results will be essential to improve clinical outcomes which remains to be determined. Conclusion: Montelukast has been suggested as a potential drug with 2 main actions on Covid-19. The validation of montelukast as an adjuvant treatment may improve lung injury, inflammation, and symptoms leading to a better prognosis. The use of this drug may fulfil the existing gap on therapeutic options

Drug Hypersensitivity Quality of Life Questionnaire: validation procedures and first results of the Portuguese version

Background: Hypersensitivity reactions to drugs are unpredictable and can be very complex and severe, even life threatening. Assess its impact on patient’s health related quality of life (HRQoL) is crucial. The Drug Hypersensitivity Quality of Life Questionnaire (DrHy-Q) is the only validated disease-specific HRQoL questionnaire. We aimed to translate and cross-cultural validate the DrHy-Q to the Portuguese population. It was also our purpose to determine the impact of drug hypersensitivity on patients’ HRQoL. Methods: The translation and cross-cultural adaptation of the DrHy-Q to Portuguese was performed according to standards. Reliability of the DrHy-Q Portuguese version was assessed in terms of internal consistency and test–retest reliability. Structural validity, divergent validity (with a generic health related QoLQ-PGWBI) and discriminant validity were also evaluated. Forty patients accepted to participate in the validation phase. The Portuguese version of the DrHy-Q was applied to 260 consecutively adult patients, studied in our Department for suspected drug hypersensitivity. Results: The Portuguese DrHy-Q showed adequate internal consistency (Cronbach’s ¿ = 0.938), good test–retest reliability [ICC = 0.713 (95% CI 0.488–0.850] and one-dimensional structure. No significant correlation was found between the DrHy-Q and the PGWBI total scores (r = - 0.010, p = 0.957). Two hundred of patients completed the study: 78.5% female; mean age = 44 ± 15 years. Mean DrHy-Q score was 36.8 ± 12.6. Two clinical factors significantly predict DrHy-Q total score: clinical manifestations and number of suspected drugs. Patients with anaphylaxis (ß = 11.005; 95% CI 5.523; 16.487), urticaria/angioedema (ß = 7.770; 95% CI 2.600; 12.940) and other manifestations (ß = 7.948; 95% CI 1.933; 13.962) are more likely to have higher DrHy-Q total score than patients with maculopapular exanthema. Patients with = 2 suspected drugs are also more likely to have worse QoL (ß = 7.927; 95% CI 3.687; 12.166). Conclusion: The Portuguese version of DrHy-Q revealed adequate validity and reliability, indicating that it is appropriate to assess the impact of drug hypersensitivity on patients’ HRQoL, providing data for a better comprehension and management of our patients. Moreover, our results highlight that the severity of the drug hypersensitivity reaction and the number of suspected drugs have impact on patient’s DrHy-QoL

OPTN recruitment to a Golgi-proximal compartment regulates immune signalling and cytokine secretion

Optineurin (OPTN) is a multifunctional protein involved in autophagy, secretion as well as NF-κB and IRF3 signalling and OPTN mutations are associated with several human diseases. Here we show that, in response to viral RNA, OPTN translocates to foci in the perinuclear region, where it negatively regulates NF-κB and IRF3 signalling pathways and downstream pro-inflammatory cytokine secretion. These OPTN foci consist of a tight cluster of small membrane vesicles, which are positive for ATG9A. Disease mutations linked to POAG cause aberrant foci formation in the absence of stimuli, which correlates with the ability of OPTN to inhibit signalling. Using proximity labelling proteomics, we identify the LUBAC complex, CYLD and TBK1 as part of the OPTN interactome and show that these proteins are recruited to this OPTN-positive perinuclear compartment. Our work uncovers a crucial role for OPTN in dampening NF-κB and IRF3 signalling through the sequestration of LUBAC and other positive regulators in this viral RNA-induced compartment leading to altered pro-inflammatory cytokine secretion

A ansiedade e os sistemas de informação em enfermagem: elaboração de um catálogo CIPE®

Contexto/Objetivos: Considerando a crescente importância dos sistemas de informação de Enfermagem em Portugal, bem como a necessidade de uma prática de Enfermagem cada vez mais baseada na evidência científica, o presente trabalho tem como principal objetivo a criação de um catálogo CIPE® para um foco de Enfermagem altamente prevalente na prática clínica: a ansiedade. Metodologia: Revisão sistemática da literatura através da análise de artigos científicos presentes nas bases de dados disponibilizadas pela EBSCO Host® (1995 a 2011), SciELO® e Web of Science® (sem datas pré-definidas) relativa aos dados relevantes e intervenções de Enfermagem para o diagnóstico “Ansiedade”. Resultados: A avaliação/vigilância da angústia, inquietação, movimento corporal, sono, nervosismo e preocupação é essencial para o diagnóstico/avaliação da ansiedade. As intervenções mais efetivas são, sobretudo, as intervenções psicoterapêuticas. A utilização de um instrumento psicométrico permite avaliar, de forma mais objetiva, os progressos realizados pela pessoa com ansiedade. Conclusões: A elaboração de catálogos CIPE® permite o desenvolvimento dos sistemas de informação de Enfermagem (SIE), constituindo ainda o caminho para uma prática de Enfermagem cada vez mais baseada na evidência científica. Ainda assim, seria fundamental, em termos de progresso, que os SIE acompanhassem a evolução que se tem vindo a verificar ao nível da linguagem classificada

Cardiovascular safety of type 2 diabetes medications: Review of existing literature and clinical implications

Type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD) and the cardiovascular effect of antidiabetic drugs are today critical medical issues, with the prevalence of T2DM in particular showing a steep increase worldwide, mainly due to unhealthy lifestyle habits. T2DM in association with obesity and other cardiovascular risk factors, results in the development of CVD, the leading cause of morbidity and mortality in patients with T2DM. Thus, treatment of T2DM is an individualized and complex challenge in which targeting cardiovascular risk factors is an important component in the decision making. Given the cardiovascular adverse events associated with rosiglitazone, both the Food and Drug Administration and the European Medicines Agency currently require the demonstration of cardiovascular safety of new antidiabetic drugs. Consequently, clinical trials to guarantee their cardiovascular safety are now obligatory. This review aims to summarize the available evidence on the cardiovascular effects and safety of the major drugs used in T2DM treatment and also to provide an overview of upcoming and ongoing clinical trials in this field. Our belief is that this review will be of substantial assistance to all medical doctors who are treating diabetic patients, namely primary care physicians, internal medicine doctors, endocrinologists, diabetologists and less well experienced personnel such as young doctors in training
