- Anarquia na cidade - A arquitectura viral como método de reabilitação da cidadePublication . Ramos, AnaA regeneração e a necessidade de repensar a cidade, senão fazem parte do pensamento do arquiteto e do designer atuais, devem rapidamente solidificar-se em cada um dos seus projetos. A cidade do Porto tem a cada esquina sombras do seu passado. Os edifícios abandonados alastram-se, evidenciando que não existe uma resposta imediata e direta às necessidades dos seus atuais habitantes. O despertar para a plenitude do futuro que se aproxima torna-se cada vez mais importante, mas a questão fulcral é: como conseguimos manter o ecletismo e a história de uma cidade recheada de memórias e ao mesmo tempo projetar obras que refletem os anseios e as necessidades da atualidade. A arquitetura viral surge como uma ponte entre o passado e o presente, onde as noções científicas sobre o parasitismo conseguem ser transportadas para a arquitetura, como um meio de injetar contemporaneidade em edifícios que se encontram estagnados nas suas épocas de nascimento. Como uma possível tipologia de reabilitação, a arquitetura viral descontextualiza o edificado, intervindo nas barreiras anteriormente estabelecidas. As regras impostas pela arquitetura rígida do passado dão lugar ao projeto arquitetónico visto como algo plástico e abstrato e abrem caminho à intervenção desinibida e desprovida de frieza na cidade.

- Composite Films of Nanofibrillated Cellulose with Sepiolite: Effect of Preparation StrategyPublication . Alves, Luis; Ramos, Ana; Rasteiro, Maria G.; Vitorino, Carla; Ferraz, Eduardo; Ferreira, Paulo J. T.; Puertas, Maria L.; Gamelas, José A. F.Cellulose nanofibrils (CNFs) are nanomaterials with promising properties to be used in food packaging and printed electronics, thus being logical substitutes to petroleum-based polymers, specifically plastics. CNFs can be combined with other materials, such as clay minerals, to form composites, which are environmentally friendly materials, with acceptable costs and without compromising the final properties of the composite material. To produce composite films, two strategies can be used: solvent casting and filtration followed by hot pressing. The first approach is the simplest way to produce films, but the obtained films may present some limitations. In the present work, CNFs produced using enzymatic or TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical) oxidation pretreatments, followed by high-pressure homogenization, or only by mechanical treatment (homogenization), were used to produce films by both the available procedures. The films obtained by filtration + hot pressing presented higher tensile strength and Young’s modulus compared with those obtained by solvent casting. In general, a decrease in the values of these mechanical properties of the films and a decrease in elongation at break, with the addition of sepiolite, were also observed. However, for the TEMPO CNF-based films, an improvement in tensile strength could be observed for 10% of the sepiolite content. Furthermore, the time necessary to produce films was largely reduced by employing the filtration procedure. Finally, the water vapour barrier properties of the films obtained by filtration are comparable to the literature values of net CNF films. Thus, this technique demonstrates to be the most suitable to produce CNF-based composite films in a fast way and with improved mechanical properties and suitable gas barrier properties.
- Contributions of the Communication and Management of Bad News in Nursing to the Readaptation Process in Palliative Care: A Scoping ReviewPublication . Moura, Teresa; Ramos, Ana; Sá, Eunice; Pinho, Lara; Fonseca, CésarBackground: Delivering bad news is a sensitive and challenging aspect of nursing healthcare, requiring a holistic approach that respects patients’ preferences, cultural values, and religious beliefs to promote adaptation to the person’s state of health. Aim: We aim to map the evidence of the dimensions present in the communication and management of bad news by nurses to a person in a palliative situation, their caregivers, and their family members. Methods: Based on the Joanna Briggs Institute methodology, the search was conducted through MEDLINE Complete (EBSCOhost), CINAHL Complete (EBSCOhost), SciELO, and the Open Access Scientific Repository in Portugal. From a total of 756 articles, 14 were included, published between 2018 and 2023. Results: Structure components in bad news are influenced by the characteristics of the palliative patients, their caregivers, their family members, the nurses, and the organizational environment. Promoting the quality of the communication process is desirable through continuous and advanced training in end-of-life care, training in bad news, religiously and culturally sensitive nursing interventions centered on hope and maintaining faith, emotional management, and the utilization of a checklist protocol. Conclusions: Honest communication allows people to actively participate in the decision-making process and in the trajectory of the care plan that is focused on themselves and their preferences, which has outcomes in functional capacities and readaptation.
- A Cross-Sectional Study of the Perception of Individualized Nursing Care Among Nurses in Acute Medical and Perioperative SettingsPublication . Ramos, Ana; Pires, Sara; Sá, Eunice; Gomes, Idalina; Alves, Elisabete; Fonseca, César; Coelho, Anabela; Coelho, AnabelaIndividualized nursing care allows for systematic assessment and intervention; considers a patient’s preferences, values, and context; and contributes to a positive care trajectory. However, its operationalization has proven to be challenging. This research aimed to evaluate nurses’ perceptions of individualized care and analyze their relationship with sociodemographic variables. Methods: A cross-sectional study was conducted on 122 eligible and registered nurses at a Hospital Center, in the Ophthalmology (operating room and inpatient ward) service, the Cardiology service, the Internal Medicine service, and the Medical Emergency Unit, for adults/older adults in Portugal. The nursing version of the Individualized Care Scale (ICS-Nurse) was used for the assessment, including three sub-dimensions: clinical situation, personal life situation, and decisional control over care-related decisions. Cronbach’s alpha and principal component analysis were used for the data analysis. The STROBE checklist was used to report this study. Results: No statistically significant differences were found based on the age, gender, level of education, or years of professional experience of the nurses within the sub-dimensions of individualization. The nurses overall had a good perception of the importance of individualized care (4.06 ± 0.46 ICS-A-NURSE) but faced difficulties in its implementation during the last shift they worked (3.97 ± 0.49 ICS-B-NURSE). Conclusions: The items considered to be of greatest importance were the response to the physical and emotional needs arising from illness and assistance in decision-making through educational instructions. Aspects related to the personal lives of patients, such as family inclusion in an individual’s care plan, everyday habits, and previous experiences of hospitalization, received the lowest scores. Recognizing priority areas for improvement in the individualization of nursing care can contribute to developing training programs and policies that promote a holistic approach. Future studies should consider patient outcomes related to their needs for individualization.

- Design of cellulose nanofibre-based composites with high barrier propertiesPublication . Alves, Luís; Ramos, Ana; Ferraz, Eduardo; J. T. Ferreira, Paulo; G. Rasteiro, Maria; A. F. Gamelas, JoséGas barrier properties are very relevant in composite materials for applications so diverse such as food packaging, electronics, or old document restoration. In the present work, four different types of cellulose nanofibres (CNFs), two types of clay minerals used individually (sepiolite) or combined (sepiolite + kaolinite), and the influence of pH, were explored in the production of composite films. Neat CNFs, only mechanically treated or prepared by enzymatic pre-treatment, gave films with good mechanical and barrier properties, but the addition of minerals led to a dramatic loss of these properties. Contrarily, the use of thin and functionalized fibrils (TEMPO-oxidised or cationized CNFs) gave composite films with good mechanical, thermal and barrier properties. Superior oxygen barrier properties (oxygen transmission rate (OTR) < 0.4 cm3 m−2 day−1) were obtained using TEMPO-oxidised CNF and 20% sepiolite, and, in general, for all the composite films containing the TEMPO CNF (OTR ≤ 1.8 cm3 m−2 day−1). The cationic CNF-based composites also showed a very good oxygen barrier (OTR ≤ 8.2 cm3 m−2 day−1). The high oxygen barrier could be explained by the compactness of the films and better entanglement of the more fibrillated nanocelluloses with the mineral particles. A decrease in the pH of the suspensions led to a decrease in the film preparation time, without a major negative impact on the composite film’s properties.
- Effect of the dispersion state of minerals on the properties of cellulose nanofiber-based composite filmsPublication . Alves, Luís; Ramos, Ana; Ferraz, Eduardo; Sanguino, Pedro; Santaren, Julio; Rasteiro, Maria Graça; Gamelas, José AFThe dispersion state and the efficiency of the mixture of the different components in a composite film have an important impact on its mechanical and optical properties. In the present work, the impacts of different dispersion treatments on the disaggregation state of fibrous clay particles in water, and on the properties of related cellulose nanofiber (CNF)-based composite films, were evaluated. X-ray diffraction studies, performed on samples of sepiolite and palygorskite, revealed only minor changes in the diffraction pattern when the minerals were subjected to ultrasonic treatment, with or without the addition of different chemical dispersing agents. Conversely, microscopic studies revealed important differences in the dispersion state of the samples, induced by the addition of the different dispersants, showing an improvement in the disaggregation of the mineral crystals. The composite films prepared with sepiolite (and carboxymethylcellulose, as chemical dispersant) dispersed using ultrasonic treatment, and different types of CNF, showed improved optical and mechanical properties when compared with composites of the same counterparts prepared with sepiolite dispersed using a high-speed shear disperser.
