Health literacy, a more complex concept than knowledge, is a required capacity to obtain, understand, integrate and act on health information [1], in order to enhance individual and community health, which is defined by different levels, according to the autonomy and personal capacitation in decision making [2]. Medium levels of Health literacy in an adolescent population were found in a study conducted in 2013/2014, being higher in sexual and reproductive health and lower in substance use. It was also noticed that the higher levels of health literacy were in the area adolescents refer to have receipt more health information. The health literacy competence with higher scores was communication skills, and the lower scores were in the capacity to analyze factors that influence health. Higher levels were also found in younger teenagers, but in a higher school level, confirming the importance of health education in these age and development stage. Adolescents seek more information in health professionals and parents, being friends more valued as a source information in older adolescents, which enhance the importance of peer education mainly in older adolescents [3]. As a set of competences based on knowledge, health literacy should be developed through education interventions, encompassing the cultural and social context of individuals, since the society, culture and education system where the individual is inserted can define the way the development and enforcement of the health literacy competences [4]. The valued sources of information should be taken into account, as well as needs of information in some topics referred by adolescents in an efficient health education. Schizophrenia is a serious and chronic mental illness which has a profound effect on the health and well-being related with the well-known nature of psychotic symptoms. The exercise has the potential to improve the life of people with schizophrenia improving physical health and alleviating psychiatric symptoms. However, most people with schizophrenia remains sedentary and lack of access to exercise programs are barriers to achieve health benefits. The aim of this study is to evaluate the effect of exercise on I) the type of intervention in mental health, II) in salivary levels of alpha-amylase and cortisol and serum levels of S100B and BDNF, and on III) the quality of life and selfperception of the physical domain of people with schizophrenia. The sample consisted of 31 females in long-term institutions in the Casa de Saúde Rainha Santa Isabel, with age between 25 and 63, and with diagnosis of schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Physical fitness was assessed by the six-minute walk distance test (6MWD). Biological variables were determined by ELISA (Enzyme-Linked Immunosorbent Assay). Psychological variables were assessed using SF-36, PSPP-SCV, RSES and SWLS tests. Walking exercise has a positive impact on physical fitness (6MWD -p = 0.001) and physical components of the psychological test...

Studies related to the work environment in primary health care are scarce in the literature. The present study aimed to validate the psychometric properties of the Practice Environment Scale of Nursing Work Index (PES-NWI) in primary health care (PHC) and to evaluate its construct validity through exploratory and confirmatory factor analyses in a sample of Portuguese nurses. A quantitative, cross-sectional, and validation study design was implemented. Methods: The sample consisted of 1059 nurses from the PHC units of all 55 health center groups (HCGs) in mainland Portugal, 15 health centers in the Autonomous Region of Madeira, and 6 health centers in the Autonomous Region of the Azores. The study tested different structural models using exploratory and confirmatory factor analysis techniques. The reliability of the scale was tested by determining Cronbach’s alpha coefficient. Results: The internal consistency of the PES-NWI was 0.91. Exploratory and confirmatory factor analyses were performed on the PES-NWI model in PHC with five factors: NPOA, NFQC, NMALSN, SRA, and CNPR. The results show that the scale presents acceptable fit quality indexes in the final factorial solution and adequate convergent validity. Conclusion: The PES-NWI in PHC has an adequate, robust, and reliable five-factor structure. The scale is valid and can be used in clinical practice, nursing management, and PHC research.

Objective: This study aims to validate the Portuguese version of the Practice Environment Scale of the Nursing Work Index (PES-NWI) and assess construct validity through exploratory and confirmatory factor analyses. Materials and Methods: This cross-sectional study validates the psychometric properties of the PES-NWI in Portugal. Exploratory factorial analysis is used to analyze the psychometric properties of the PES-NWI in a sample of 5,075 Portuguese nurses; the data sample covers all geographic regions in the country. Confirmatory factor analysis is performed to confirm the model’s data adequacy. Results: Factorial analysis explained 54.6 % of the variance and a five-dimension structure. The five factors identified were Nurse Participation in Hospital Affairs, Nurse Manager Ability, Leadership and Support of Nurses, Nursing Foundations for Quality of Care, Staffing and Resource Adequacy, and Nurse-Physician Relations. The confirmatory analysis showed that the five-factor model fit well with the data in the Portuguese context. Conclusion: In a Portuguese health context, the PES-NWI is a valid scale to access the nursing environment and improve working conditions.

Acetylsalicylic acid, commercially available as aspirin, is one of the most used drugs in the world, being detected in several environmental compartments, including drinking water supplies. Given its environmental impact, the development of a cost-effective technology capable of removing this pharmaceutical from water samples is of high relevance, for which materials based on silica chemically modified with ionic liquids (SILs) can be foreseen as a promising alternative. In this work, four SILs (with the chloride anion and imidazolium or tetraalkylammonium cations of different alkyl side chain length) were synthesized and characterized, and their potential for the adsorption of acetylsalicylic acid appraised by adsorption kinetics and isotherms. Envisioning their use to treat drinking water, the toxicity of all SILs towards the liver cell line Hep2G was determined.The best identified SIL, comprising the dimethylbutylammonium cation, displays a maximum adsorption capacity of 0.08 mmol/g, being 1 g of this material sufficient to treat ca. 14,500 L of water containing 1 μg/L of acetylsalicylic acid (under ideal conditions). Furthermore, this material has a negligible toxicity towards the liver cell line Hep2G. The results obtained reinforce the potential of SILs as alternative adsorbents to effectively remove acetylsalicylic acid from aqueous solutions, and may be envisioned as a promising strategy for the treatment of wastewater and drinking water.

Objective: adapt and validate the instrument Children Care Quality at Hospital (CCQH) to assess the quality of nursing care of hospitalized children for the Portuguese language of Portugal. Materials and Methods: content, language, and conceptual validity methodological study, with translation, feedback, and reflection. A non-probabilistic simple was used of 252 children between 7 and 11 years of age, hospitalized due to acute disease in nine services of six Portuguese hospitals. The reliability and validity of the results were determined to measure the psychometric properties of the instrument. Construct validity was calculated through exploratory factor analysis of main components with Varimax rotation and the internal consistency by determining the Cronbach’s alpha coefficient. Results: the internal consistency has adequate psychometric characteristics suitable for the Portuguese population (Cronbach’s alpha values between 0.66 and 0.82). The instrument maintained 49 items grouped into three categories: characteristics, activities, and environment. The psychometric characteristics of the CCQH, adapted and validated for Portuguese, guarantees its reliability and validity to measure satisfaction with the quality of nursing care from the perspective of school-aged children. Conclusions: the instrument could be used to assess children’s satisfaction with the quality of nursing care during their hospitalization.
