Investigação de surto em navio de carga em tempo de COVID-19, Porto de Santos, Brasil

Em fevereiro de 2020, um navio de carga vindo da China atracou no Porto de Santos com relato de tripulantes com quadro febril e respiratório. Uma equipe foi mobilizada para verificar a existência de casos suspeitos de COVID-19 dentro da embarcação e definir a liberação da embarcação no porto. Todos os 25 tripulantes foram entrevistados e não foram encontrados casos suspeitos. Então a embarcação foi liberada para atividades no porto. A investigação resultou da aplicação do plano de contingência diante de uma emergência de saúde pública de importância internacional e houve a colaboração de diversas entidades de vigilância.In February 2020, a Chinese cargo ship docked at the Port of Santos with reports of crew members with a feverish and respiratory condition. A team was gathered to verify the existence of suspected cases of COVID-19 inside the vessel and define its clearance. All 25 crew members were interviewed, and no suspected cases were found. The vessel was then cleared for port activities. The investigation resulted from the implementation of the contingency plan to face a public health emergency of international importance and several surveillance entities cooperated

Gait monitoring system for patients with Parkinson’s disease

Background: Wearable monitoring devices based on inertial sensors have the potential to be used as a quantitative method in clinical practice for continuous assessment of gait disabilities in Parkinson’s disease (PD). Methods: This manuscript introduces a new gait monitoring system adapted to patients with PD, based on a wearable monitoring device. To eliminate inter- and intra-subject variability, the computational method was based on heuristic rules with adaptive thresholds and ranges and a motion compensation strategy. The experimental trials involved repeated measurements of walking trials from two cross-sectional studies: the first study was performed in order to validate the effectiveness of the system against a robust 3D motion analysis with 10 healthy subjects; and the second-one aimed to validate our approach against a well-studied wearable IMU-based system on a hospital environment with 20 patients with PD. Results: The proposed system proved to be efficient (Experiment I: sensitivity = 95,09% and accuracy = 93,64%; Experiment II: sensitivity = 99,53% and accuracy = 97,42%), time-effective (Experiment I: earlies = 13,71 ms and delays = 12,91 ms; Experiment II: earlies = 12,94 ms and delays = 12,71 ms), user and user-motion adaptable and a low computational-load strategy for real-time gait events detection. Further, it was measured the percentage of absolute error classified with a good acceptability (Experiment I: 3,02 ≤ ε%≤12,94; Experiment II: 2,81 ≤ ε%≤13,45). Lastly, regarding the measured gait parameters, it was observed a reflection of the typical levels of motor impairment for the different disease stages. Conclusion: The achieved outcomes enabled to verify that the proposed system can be suitable for gait analysis in the assistance and rehabilitation fields.This work was supported by FCT national funds, under the national support to R&D units grant, through the reference project UIDB/04436/2020 and UIDP/04436/2020, and under the Reference Scholarship under grant SFRH/BD/136569/2018

Vibrotactile biofeedback devices in Parkinson’s disease: a narrative review

Parkinson’s disease (PD) is often associated with a vast list of gait-associated disabilities, for which there is still a limited pharmacological/surgical treatment efficacy. Therefore, alternative approaches have emerged as vibrotactile biofeedback systems (VBS). This review aims to focus on the technologies supporting VBS and identify their effects on improving gait-associated disabilities by verifying how VBS were applied and validated with end-users. It is expected to furnish guidance to researchers looking to enhance the effectiveness of future vibrotactile cueing systems. The use of vibrotactile cues has proved to be relevant and attractive, as positive results have been obtained in patients’ gait performance, suitability in any environment, and easy adherence. There seems to be a preference in developing VBS to mitigate freezing of gait, to improve balance, to overcome the risk of fall, and a prevalent use to apply miniaturized wearable actuators and sensors. Most studies implemented a biofeedback loop able to provide rescue strategies during or after the detection of a gait-associated disability. However, there is a need of more clinical evidence and inclusion of experimental sessions to evaluate if the biofeedback was effectively integrated into the patients’ motor system.This work was supported by FCT national funds, under the national support to R&D units grant, through the reference project UIDB/04436/2020 and UIDP/04436/2020, and under the Reference Scholarship under Grant SFRH/BD/136569/2018

Climate-responsive strategies of vernacular architecture in Albania and Portugal

The influence of climate on vernacular architecture is widely recognised. In the case of the Mediterranean Sea, its influence on climate ranges a wide variety of territories and cultures. Therefore, it is relevant to study how the climatic factor has modelled vernacular architecture in those territories and if there are common features. In this exploratory study are qualitatively compared the climate-responsive strategies of vernacular architecture from two countries located on opposite sides of the Mediterranean basin, namely, Portugal and Albania. The pragmatism of these strategies, developed on the need of adaptation to a specific climate and territory, may con-tribute to reduce energy consumption and waste. The study allowed showing points of similarity between strategies used in the two countries and, understanding how these strategies influence indoor comfort conditions. The results of the study can be used to develop and integrate these strategies in the current construction context, contributing to its sustainability.The authors would like to acknowledge the support granted by the Portuguese Foundation for Science and Technology (FCT) in the scope of the Doctoral Program Eco-Construction and Rehabilitation that supports the PhD scholarship with the reference PD/BD/113641/2015, that was fundamental for the development of this study.info:eu-repo/semantics/publishedVersio

Osler-Weber-Rendu Syndrome - Dental Implications

Osler-Weber-Rendu syndrome (OWRS) is a rare hereditary, autosomal dominant disease characterized by a local angiodysplasia. Its clinical characteristics are vascular hamartomas of the skin and oral mucosa, arteriovenous malformations in the lungs, liver, kidney and brain, and episodes of epistaxis. The oral lesions, which become apparent through hemorrhagic telangiectasia, may be the first sign of the disease. This is a case report of a 74-year-old woman whose diagnosis of OWRS was established by her dentist based on the presence of telangiectasia in the skin and oral mucosa, reports of frequent nosebleeds of unknown etiology and a family history of telangiectasia. Amputation of a lower limb and comorbidities, such as cardiopathy, nephropathy and rheumatic disorders, completed the profile. OWRS causes major vascular changes that can be diagnosed initially by a dentist. In this article, we describe the skills and knowledge that dentists need to monitor patients with OWRS properly

O trabalho experimental de investigação: das expectativas dos alunos às potencialidades no desenvolvimento de competências

Da análise da literatura actual sobre trabalho experimental (TE), sobressai como consensual a defesa de uma perspectiva de orientação investigativa do mesmo, a  qual é encarada como uma alternativa válida a práticas mais tradicionais de utilização de TE nas aulas de ciências, pelo facto de possibilitar o desenvolvimento de competências científicas pelos alunos. Nesta comunicação serão apresentados resultados de uma experiência, desenvolvida em contexto de sala de aula, que envolveu a concepção e implementação de TE de investigação e que pretendeu averiguar a valorização atribuída pelos alunos nela envolvidos ao TE de orientação investigativa, relativamente ao TE de verificação que habitualmente realizavam e inferir, a partir da opinião por eles manifestada, sobre as potencialidades do TE de investigação, relativamente ao TE habitualmente realizado, no desenvolvimento de competências atitudinais e procedimentais

Gestión del procedimiento de la higiene de las manos por enfermeros: desafíos para la salud colectiva

Objective: To describe the determining factors in hand hygiene management among nurses and identify associated collective health challenges. Method: Cross-sectional descriptive study. Data were collected using a questionnaire that was applied in four internal medicine units of a hospital of reference in Portugal. Results: The sample was composed of 50 nurses aged 26 to 55 years (mean age of 34.88 years); 80% were women, 58% had a Bachelor’s degree, and had 5-30 years of nursing practice (X̄ =11.94;±5.92). The vast majority of nurses (90%) reported complying with the existing recommendations on hand hygiene in pre-established moments. However, none of the nurses were able to identify all the moments for hand hygiene using water and soap or alcohol-based handrub. Conclusion: This study shows that continuous training, adequate materials/structures in the units, and redesigned administration/supervision practices are determining factors to achieve higher levels of adherence to hand hygiene among nurses, as well as increased quality and safety in care delivery, which is a current collective health challenge.
