- Critical patient’s comfort: strategies to reduce environmental noise levelsPublication . Ramos, Telma; Veludo, FilipaBackground: Noise may have harmful effects. For critically ill patients, highlights have main consequences cardiovascular disorders, reduction of arterial oxygen saturation, increase in gastric secretion, stimulation of the pituitary gland, sleep disturbance, immunosuppression and reduction of the cicatrisation process [1]. Noise has an overall negative impact on patients’ recovery. Identification and dissemination of strategies to reduce environmental noise empowers nurses towards changes in their professional practice. Objective: Identify evidence in Literature of nursing care strategies to reduce environmental noise in critical patient care. Methods: This research was conducted in two phases. 1st Phase: Mediated by an integrative literature review (16/04/2017) we carried out data-base research through the Academic Search Complete; Complementary Index; CINAHL Plus with Full Text; Directory of Open Access Journals; Supplemental Index; Psychology and Behavioural; Sciences Collection; SPORTDiscus with Full Text; RCAAP; SciELO; Europeana; Business Source Complete; Education Source; IEEE Xplore Digital Library; MedicLatina; JSTOR Journals; PsycARTICLES; ScienceDirect. Descriptors: (TI (Noise*or sleep*) AND (Nurs*) AND (intervention or care or patient care or care plan* or critical care), non-temporal. Inclusion criteria: Primary, secondary, opinion/reflexion studies. Exclusion Criteria: Paediatrics context, REM, pharmacological intervention. From the initially 441 articles obtained, we excluded 391 by reading abstracts, 22 by summary and 15 by the complete text, concluding with 13 articles as final sample. 2nd Phase: Content analysis according to [2] in order to categorize results. Results: We have identified 6 feasible categories for environmental noise reduction, which we present as main strategies: Behavioural changes (creation of awareness to the importance of the tone of voice and silent handling of equipment and materials); Material and Equipment management (mobile phones, televisions and radios volume configuration; determination of correct parameters for alarm configuration); Management of silence promotion care (implementation of periods of silence, avoid noisy tasks); Training in environmental noise (behavioural change programs and health education about negative effects of noise); Care quality control (usage of ear plugs); Others (infrastructural adaptations, encourage suppliers to produce more silent products). Conclusions: This study systematizes strategies to be implemented by nursing professionals in order to reduce environmental noise within health structures and improve patient comfort. The implementation of a silence culture enables an adequate and essential physical environment to patient recovery [3]. Empower nurses with the identified strategies allows the improvement of people’s quality of life. The shortage of published research reflects the need of forward research.
- Strategies to improve hand hygiene practices: an integrative literature reviewPublication . Mestre, Ana C.; Veludo, Filipa; Freitas, SusanaBackground: Healthcare-associated infections (HAIs) are a global concern and pose a real threat to patient safety. Many of them preventable [1]. Knowing that hands of healthcare professionals are one of the main vehicles in the transmission of microorganisms, hand hygiene (HH) is recognized as the easier and most effective measure to prevent and reduce HAIs [2]. However, despite all evidence available and although 98% of healthcare professionals consider HH as the most important basic precaution in preventing HAIs, compliance is poor, remaining less than 40% [3,4]. Objective: To identify, in Literature, the most effective strategies to promote HH compliance. Methods: An integrative review between September and October 2017 was fulfilled with the Boolean strategy: [(TI Title) hand hygiene AND (AB Abstract) nurse AND (AB Abstract) infection AND (AB Abstract) strategy OR compliance OR adherence] in CINAHL®, Science Direct and Academic Search Complete. A total of 396 articles were identified, initially. After applying the inclusion criteria: primary and secondary studies with a qualitative and quantitative approach available in full text in Portuguese, English, French and Spanish; and exclusion criteria: studies published before 2016, a sample of 12 articles was included for analysis. Results: From a total of 12 articles analysed, 10 showed the importance of a multimodal approach to the improvement of HH practices with consequent increase in compliance to this behaviour. It stands out the combination of interventions addressing knowledge (education), awareness, context of action (reminders in the workplace) as well as the involvement and support of leaders and managers in building an institutional safety culture (social influence) as the most effective to ensure greater compliance to HH. Conclusions: In order to improve HH practices and, consequently, adherence to this behaviour, the adoption of a multimodal strategy proved to be more successful when compared to single interventions. At an early stage, it is essential to understand the reasons that lead to non-adherence to HH and after that design interventions based on identified barriers. The approach should be global, including not only healthcare professionals but also leaders and managers.

- Os efeitos de uma proposta didática de educação auditiva na performance musicalPublication . Cardoso, Mário; Morgado, Elsa; Silva, LeviOne of the challenges of the contemporary educational musical context is the urgency of building and developing a multidisciplinary and multidimensional vision that can, on the one hand, contribute to the overcoming of fragmented pedagogical practices of the context and musical syntax, and, on the other hand, contextualize and develop a set of auditory, cognitive and expressive abilities. This fact is observed in the pedagogical practices of the curricular units associated to the construction and development of the musical formation of the individuals, whose paradigms are based on the technical-expressive development, isolation of fundamental elements of the musical syntax and lag between contemporary production and its teaching processes and learning. Based on the relevance and contemporaneousness of these pedagogical practices in the current context, an experimental, methodological approach was developed to verify if the implementation of a multidimensional and multidimensional model of auditory education affects performance improvement and understanding. This empirical research was developed in a context of Higher Education, using an experimental, methodological line, with a control group with pre-test and post-test. From the analysis and interpretation of the results emerge indicators that the teaching and learning process is based on the Multidimensional Model of Auditory Education, contributes to the development of learning and recognition of elements (rhythmic and metrical structure, melodic and harmonic organization, expressive elements and stylistic and instrumental diversity) fundamental in the understanding of musical syntax.

- Effect of salt on EPS production by halotolerant bacteria for aerobic granular sludge treatmentPublication . Paulo, A. M. S.; Amorim, Catarina L.; Castro, P. M. L.Extracellular polymeric substances (EPS) are overproduced by some microbes as a response to stress. The diverse composition of microbial EPS confers unique properties to these biopolymers, which find application in the food industry (e.g., thickening agents) or in the wastewater treatment (e.g., flocculants). The aerobic granular sludge (AGS) process is a promising biotechnology which relies on EPS-producing bacteria for granule formation and stability. One of the current challenges is to use the AGS process to treat high salinity wastewater. Bioaugmentation with EPS-producing halotolerant bacteria can be used as strategy to increase the robustness of AGS to high salinity. The aim of the present study was to retrieve halotolerant EPS producers from wastewater and to investigate EPS production at varying salt levels. Bacteria were isolated from brine wastewater collected in a fish canning plant. Ten isolates were compared for biofilm production (potential EPS producers) using different carbon sources and NaCl concentration (0 to 40 g L-1). Four isolates were selected for EPS production, in a medium with salt concentration up to 40 g NaCl L-1 and using saline wastewater from a fish canning plant. The EPS content in proteins, humic acids and carbohydrates was quantified. The four most promising EPS producing bacteria belonged to the Kocuria (isolate A1), Psychrobacter (isolate H3) and Acinetobacter (isolates H4 and CX1) genera. Isolate A1 was the best biofilm producer, forming more biofilm compared to the other isolates with acetate (10 g L-1) and 20 or 40 g L-1 of NaCl. In the presence of the highest salt concentration (40 g NaCl L-1), isolate A1 produced more EPS, containing a higher percentage of carbohydrates in its composition. These EPS producers are being assessed for bioaugmentation of an AGS process treating high salinity wastewater.
- End of life person’s evaluation criteria in the decision making regarding artificial nutritionPublication . Afonso, Tânia; Veludo, Filipa; Sousa, Patrícia P.; Santos, SóniaBackground: Artificial nutrition at the end of life is assumed as a medical intervention, however for a large percentage of person’s and families is considered as basic care [1]. Thinking about artificial nutrition and the end of life person, such as the person with advanced, incurable and progressive disease, with a survival expectancy between 3 to 6 months [2] is often reflected on a set of issues. This is a controversial discussion, about the quality of life resulting of one of these means and ethical questioning [3]. It’s relevant to look to the user/family as one, which motivates the urgent intervention of the nurses in decision-making support. Objective: Identify scientific evidence regarding the end-of-life evaluation criteria, to be considered in the nurses’ decision-making about artificial nutrition. Methods: Literature Review (15-06-2017) with PRISMA guidelines for reviews [4] in Academic Search Complete, Complementary Index, CINAHL Plus with Full Text®, Psychology and Behavioural Sciences Collection, ScieELO, MEDLINE®, Directory of Open Access Journals, Supplemental Index, ScienceDirect, Education Source, Business Source Complete and MedicLatina. Inclusion/exclusion criteria: nurses who care for adult/elderly persons at the end of life, excluding nurses who care for children; articles about nurses’ intervention in nutrition care to the person at the end of life and the person’s evaluation criteria; full text; in French/Spanish/English/Portuguese; peer-reviewed; published between 2000-2017. A sample of 11 articles was selected. Results: The evaluation criteria to be considered when making decisions on artificial nutrition are: the evaluation of symptoms/problems; emotional value of food; the meaning of the diet for the person at the end of life and definition of prognosis [3,5-6]. In every decision-making, it should be considered the existence of a clinical indication/treatment, a therapeutic objective and the informed consent of a user or legal guardian. Conclusions: It is concluded that the decision on artificial nutrition should integrate the person at the end of life and family, be taken by an interdisciplinary team, considering the definition of the prognosis and the effectiveness of the treatment applied [3]. The intervention of the nurse is understood as a primordial one, based on the best evidence, in relation of proximity [5] considered, simultaneously, the principle of autonomy, beneficence, non-maleficence and justice. There is little evidence of end-of-life nutrition and new studies on the role of nurses within the interdisciplinary team are suggested.
- Effect of dual anthropogenic stresses on exopolysaccharide production by aerobic granular sludgePublication . Amorim, Catarina L.; Parmaki, Stela; Henriques, Isabel; Castro, Paula M. L.Industrial wastewater streams are difficult to manage due to their complexity, often containing several organic and inorganic compounds, such as toxic/recalcitrant organics, ammonium and inorganic salts. Aerobic granular sludge (AGS) technology has been widely investigated for the treatment of urban and industrial wastewater and its implementation at full-scale is growing worldwide. AGS is a special type of biofilm, formed via self-aggregation of microorganisms in an extracellular polymeric substances (EPS) matrix. EPS produced by microorganisms are crucial not only for granules formation and stability but also to protect cells against harsh conditions in the living environment which often occur in industrial wastewater streams.In this study, the combined effect of different anthropogenic substances on the EPS production by AGS was evaluated.
