RESUMEN
AIM: To evaluate the effectiveness on lifestyle change of an mHealth intervention to promote healthy behaviours in adolescence (TeenPower) and to analyse the predictors of the mHealth intervention effectiveness. DESIGN: This study is designed as a non-randomized controlled trial with a two-arm structure. METHODS: Adolescents of 12-16-year old were recruited from three school districts, with access to the Internet and smartphone/tablet devices. The intervention group was invited to engage in the mHealth intervention (TeenPower) for 6 months in addition to a school-based intervention. The control group only followed the school-based intervention. A repeated measures factorial ANOVA was used and the main effectiveness outcome was the lifestyle change measured by the adolescent lifestyle profile. RESULTS: The outcomes of the mHealth intervention (TeenPower) show a significant effect on nutrition (Æ2 p = 0.03, p = .03), positive life perspective (Æ2 p = 0.04, p = .01), and global lifestyle (Æ2 p = 0.02, p = .05), with a dropout rate of 62.1%. The analysis of the effectiveness predictors of the mHealth intervention suggested that older adolescents tended to show a significant increase in the rates of stress management (r = .40; p < .05). CONCLUSIONS: Although the considerable dropout rate, the mHealth intervention presented significant impact on multiple lifestyle domains, providing support for the effectiveness of mHealth interventions for health promotion as an add-on to standard interdisciplinary interventions. IMPACT: Adolescents must have the necessary and appropriate knowledge for the correct and responsible decision-making regarding their health and lifestyle. Innovative strategies (mHealth intervention) were used to promote healthy behaviours. This study evaluates the effectiveness of an mHealth intervention (TeenPower) specifically designed for adolescents. We found a significant impact in several lifestyle domains such as health responsibility, nutrition, positive life perspective, and global lifestyle.

BACKGROUND: The aim of this study was to assess the self-care dependency levels of the dependent person at the time of home discharge and its relationship between (1) the degree of dependency of each self-care domain; (2) the previous dependency levels; and (3) the gender of the dependent person. It also aims to assess the relationship between the degree of dependency of each self-care domain, the length of admission, the length of dependency and the age of the dependent person at the time of discharge. METHODS: A cross-sectional study was conducted. The sample comprised hospitalised adults and elderly in the medical services of a Portuguese hospital during the months of March, April and May of 2018. The data were collected by an interview conducted at the time of home discharge from the hospital medical ward. RESULTS: The average age of dependent people of the sample is 80.7 years (±10.1) with the majority being women (51.7%), with no statistical difference in the mean age according to gender (U = 2205.500; p > 0.05). They were hospitalised on average 11.4 days (±33.2), most of them (44.0%) due to respiratory problems (85% of which were due to pneumonia). There were no statistically significant differences between the length of the hospital stay, the length of dependency and the participants' gender (U = 2200.500, p > 0.05; U = 1688.000, p > 0.05). Medication intake was the highest dependency domain amongst participants (41.3%), followed by instrumental activities of daily living (40.6%) and bathing (39.9%). CONCLUSION: The amount of support required may vary according to the domain that the person is dependent. Thus, it is important to use a robust and reliable assessment tool that will be able to assess the degree of dependency on the various domains of self-care.

BACKGROUND: The world is facing many socio-demographic changes, such as an increased average life expectancy and the presence of chronic and non-communicable diseases, which in turn, leads to an enhanced dependency on others. Consequently, the demand for informal caregivers has significantly increased during the past few years. Caring for a dependent person is linked to a series of burdens that often leads to physical, psychological and emotional difficulties. Taking into consideration the difficulties faced by informal caregivers, knowing in which areas of functioning they need more guidance may help to relieve their burden. Therefore, the main goal of this study is to better understand the needs and competencies of the informal caregiver when caring for a dependent person in the different self-care domains. METHODS: This cross-sectional study used a questionnaire administered on a single occasion by face-to-face interview. Descriptive and inferential statistics alongside non-parametric statistical techniques such as the Mann-Whitney test and Spearman's correlation were used. RESULTS: The average age of the 143 informal caregivers is 58 years old, with the youngest in our sample being 21 years of age. Most of them are female, and 50% of them are children taking care of one of their parents. Most of the dependent people are completely dependent in the areas of comfort and hygiene (53.8%) and medication management (55.9%). The female informal caregivers see themselves as having more competencies in sanitary hygiene than the male ones, with no significant differences in their competencies' perception in the other areas of self-care. Older caregivers see themselves as less competent in certain areas of self-care such as feeding, mobility, transfers, medication and symptoms management and communication. Most of the information given to the informal caregiver is about the disease (82.3%) and the medication management (80.4%). There are still a lot of areas of self-care, where no information, or almost none, is given to the informal caregivers. CONCLUSIONS: Before home discharge of a dependent person, it is important to acknowledge the needs and competencies of the informal caregiver, to capacitate them in looking after their relatives, to help decrease their burden and consequently, decrease the number of hospital readmissions.

This research sought to describe the care provided by the nursing staff of the Western Department of the Basic Emergency Service for end-of-life patients. This was a retrospective, quantitative, exploratory and descriptive (level I) study, which sought to research the nursing records of 83 patients from admission to death. Patients who met the following inclusion criteria were considered eligible: adults; had an oncological or nononcological, advanced and irreversible chronic disease; and died in the Basic Emergency Service in the period from January 2011 to December 2012. An instrument was created for data collection, the content, relevance and adequacy of which was validated by a panel of experts in the area of palliative care. The study protocol was approved by the Institutional Ethics Committee. The main results indicate that the majority of patients died in the Observation Room in a period between the first two and twenty-four hours. Nursing interventions favoured technical-instrumental care related to medical prescriptions and service routines such as venous punctures, catheterisations, taking blood samples for analysis, aspiration of secretions, intravenous administration of fluids and drugs for symptomatic control, and monitoring of vital parameters and the state of consciousness. With the proximity of death, the nurses favoured the registration of cardiorespiratory arrest, cardiopulmonary resuscitation manoeuvres and aspiration of secretions. In the recognition of predictive factors of imminent death, the nurses favoured the patient's entry into a comatose state and aggravation of asthenia. In most patients, the entry into agony phase was not diagnosed.

This pilot study was conducted using a sample of 374 Portuguese occupational therapists to evaluate burnout levels and prevalence among occupational therapists as well as to relate those levels to practitioner age, gender, client age, years of professional activity, and area of practice. The Copenhagen Burnout Inventory questionnaire (Portuguese version) and a sociodemographic questionnaire was used. Results showed that â¼23%, 44%, and 45% of occupational therapists presented with client-related burnout, personal burnout (PB), and work-related burnout, respectively. Higher rates of burnout were observed across all dimensions as the age of the professionals increased, with more years of working increased the client-rated rate, and client age increased the PB rate. Outcomes suggest a need to implement intervention programs to promote personal and organizational strategies to prevent burnout.

OBJECTIVE: To evaluate the level of knowledge and the availability of the Portuguese population to attend training in Basic Life Support (BLS) and identify factors related to their level of knowledge about BLS. METHOD: Observational study including 1,700 people who responded to a questionnaire containing data on demography, profession, training, interest in training and knowledge about BLS. RESULTS: Among 754 men and 943 women, only 17.8% (303) attended a course on BLS, but 95.6% expressed willingness to carry out the training. On average, they did not show good levels of knowledge on basic life support (correct answers in 25.9 ± 11.5 of the 64 indicators). Male, older respondents who had the training and those who performed BLS gave more correct answers, on average (p<0.01). CONCLUSION: The skill levels of the Portuguese population are low, but people are available for training, hence it is important to develop training courses and practice to improve their knowledge.

BACKGROUND: The incidence and mortality of pleural mesothelioma (PM) reflect the production and consumption of asbestos over time. However, despite the current global concern, these data remain to be known. OBJECTIVE: Our aim was to carry out a descriptive analysis of PM cases and mortality from some Portuguese databases between 2014 and 2020. METHODS: A retrospective observational study was carried out between 2014 and 2020. Data on the number of PM cases were provided by the Portuguese Cancer Registry, and data on mortality were from the Portuguese Death Certificate Information System. RESULTS: Between 2014 and 2020, 315 cases of PM were reported, with 222 (70.5%) men. The average age of patients was 72.1, with the highest number of cases in patients aged >70 years (n = 198; 62.9%). The highest number of cases was reported in 2018 (n = 62; 19.7%). Regarding mortality, 169 deaths were reported, with 126 (74.6%) men and mostly in individuals aged >70 years (n = 109; 64.5%). It is estimated that around 520 years of potential life were lost. The highest number of deaths occurred in 2015 (n = 33; 19.5%). CONCLUSION: It is mandatory to reinforce the need for surveillance programs that allow us to gather real and reliable data and eliminate asbestos-related diseases.
RESUMEN
OBJECTIVE: to compare the decision-making of Nursing students, before and after theoretical training on basic life support, using the practice of high-fidelity simulation and medium-fidelity simulation. METHOD: an experimental study was developed, pre- and post-test type, with quantitative, descriptive and inferential analysis, with theoretical training on basic life support and clinical simulation practices, and with evaluation of knowledge and decision-making of Nursing students, at three different moments - before the simulation scenario (T0), after the simulation scenario (T1) and after clinical teaching (T2). RESULTS: 51 students participated in the research, with an average age of 20.25±3.804, of which 92.2% were female. Statistically significant differences (F=6.47; p=0.039) were evident regarding the definition of the problem and development of objectives in decision-making in the experimental group. CONCLUSION: Nursing students demonstrate an adequate level of knowledge and a good decision-making process, based on the most current instruments produced by scientific evidence, in clinical simulation scenarios in basic life support, and this innovative methodology should be deepened in the Nursing teaching. HIGHLIGHTS: (1) Clinical simulation promotes good decision-making of Nursing students.(2) Students demonstrated adequate knowledge about basic life support.(3) Knowledge and practice define the fidelity of clinical simulation.(4) Basic life support can be developed by high-fidelity simulation.

BACKGROUND: Effective medication management is one of the essential preconditions for enabling polymedicated home-dwelling older adults with multiple chronic conditions to remain at home and preserve their quality of life and autonomy. Lack of effective medication management predisposes older adults to medication-related problems (MRPs) and adverse health outcomes, which can lead to the degradation of a patient's acute clinical condition, physical and cognitive decline, exacerbation of chronic medical conditions, and avoidable health care costs. Nonetheless, it has been shown that MRPs can be prevented or reduced by using well-coordinated, patient-centered, interprofessional primary care interventions. OBJECTIVE: This study aimed to explore the feasibility and acceptability of an evidence-based, multicomponent, interprofessional intervention program supported by informal caregivers to decrease MRPs among polymedicated home-dwelling older adults with multiple chronic conditions. METHODS: This quasi-experimental, pre-post, multisite pilot, and feasibility study will use an open-label design, with participants knowing the study's objectives and relevant information, and it will take place in primary health care settings in Portugal and Switzerland. The research population will comprise 30 polymedicated, home-dwelling adults, aged ≥65 years at risk of MRPs and receiving community-based health care, along with their informal caregivers and health care professionals. RESULTS: Before a projected full-scale study, this pilot and feasibility study will focus on recruiting and ensuring the active collaboration of its participants and on the feasibility of expanding this evidence-based, multicomponent, interprofessional intervention program throughout both study regions. This study will also be essential to projected follow-up research programs on informal caregivers' multiple roles, enhancing their coordination tasks and their own needs. Results are expected at the end of 2024. CONCLUSIONS: Designing, establishing, and exploring the feasibility and acceptability of an intervention program to reduce the risks of MRPs among home-dwelling older adults is an underinvestigated issue. Doing so in collaboration with all the different actors involved in that population's medication management and recording the first effects of the intervention will make this pilot and feasibility study's findings very valuable as home care becomes an ever more common solution.

RESUMEN
Ageing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of home-dwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face structured interviews. Frailty, cognitive status, medication management and clinical and sociodemographic variables were evaluated. Descriptive and inferential statistics were calculated. The mean participant age was 76.6 ± 7.1 years, 53.6% of participants were women, and 40.2% of participants lived alone. More than half were classified as having frailty (58.9%), almost one-fifth (19.6%) presented with a moderate cognitive impairment had more than one disease, and 60.7% were polymedicated. No associations were found between polymedication and medication self-management, the use of over-the-counter medications, living alone, having a poor understanding of pharmacological therapy and/or pathology, or having more than one prescriber. Self-management was associated with age, the number of medications, frailty and cognitive status. Binary logistic regressions showed that cognitive impairment had statistically significant differences with medication management, having a poor understanding of pharmacological therapy and/or pathology, having one prescriber and the use of medications not prescribed by physicians. Interventions to prevent medication-related problems in home-dwelling older adults are recommended.

As a chronic disease with consistent relapse rates, substance use disorders (SUD) require a continuity-of-care approach. Unfortunately, many patients do not have access to continuing care. This systematic review analysed the current scientific knowledge to better understand if app-based smartphone interventions can be an effective alternative. The databases Cochrane Library, PubMed, Web of Science, and PsycINFO were used to find experimental and quasi-experimental studies investigating the effectiveness of a smartphone intervention in individuals who had completed treatment for SUD. After removing duplicates, a total of 1488 studies were screened, with 48 being selected for a full-text review. Four studies met all the criteria, with one other being added by identification through other resources, making a total of 5 studies included in the present review. Out of the four studies using a control group, only one found no significant differences in favour of the experimental group. That study used an active control group and compared the smartphone intervention to its therapeutic group equivalent. There were no significant differences between the two experimental groups. Overall, the results indicate that app-based smartphone interventions can be an effective alternative to traditional forms of continuing care. However, literature is still scarce, and more research needs to be made on this subject. This systematic review is registered at PROSPERO with the identifier [CRD42021272070].

Background: Substance abuse has an impact on various cognitive domains, including memory. Even though this impact has been extensively examined across different subdomains, false memory has been sparsely studied. This systematic review and meta-analysis seek to synthesize the current scientific data concerning false memory formation in individuals with a history of substance abuse. Methods: PubMed, Scopus, the Cochrane Library, Web of Science, and PsycINFO were searched to identify all experimental and observational studies in English, Portuguese, and Spanish. Studies were then examined by four independent reviewers and, if they met the inclusion criteria, assessed for their quality. The Cochrane Risk of Bias Tool for randomized controlled trials (RCT) and the Joanna Briggs Institute (JBI) critical appraisal checklists for quasi-experimental and analytic cross-sectional studies were used to assess the risk of bias. Results: From the 443 screened studies, 27 (and two more from other sources) were considered eligible for full-text review. A final 18 studies were included in the present review. Of these, 10 were conducted with alcoholics or heavy drinkers, four focused on ecstasy/polydrug users, three were done with cannabis users and one focused on methadone maintenance patients with current cocaine dependence. Regarding false memory type, 15 studies focused on false recognition/recall, and three on provoked confabulation. Conclusions: None but one of the studies considering false recognition/recall of critical lures found any significant differences between individuals with a history of substance abuse and healthy controls. However, most of the studies taking into account false recognition/recall of related and unrelated events found that individuals with a history of substance abuse showed significantly higher rates of false memories than controls. Future research should continue to consider different types of false memories as well as their potential association with relevant clinical variables.

RESUMEN
The present study about falls among the older adult population essentially explores bio-physiological factors. In light of the complexity of the factors that cause these accidents, it is important to identify the safety and self-care practices of institutionalized older adults and their relationship with falls in order to introduce prevention measures and personalized cognitive-behavioral strategies. The objective of this study was to: (a) determine the frequency of falls and their recurrence among institutionalized older adults, and (b) to associate the occurrence of falls among institutionalized adults with or without cognitive impairment to communication and safety practices. This was a quantitative, correlational, and longitudinal study with 204 institutionalized older adults living in two long-term care facilities in Portugal. The Scale of Practices and Behaviors for Institutionalized Elderly to Prevent Falls was administered to the sample. The prevalence of falls at a 12-month follow-up was 41.6%, of which 38.3% were recurring episodes. Older adults with cognitive decline showed lower mean scores for safety practices. Further research with larger samples should explore the relationships between communication and safety practices and falls, their recurrence, and fear of new falls.

The Help2Care e-Health platform was developed in order to capacitate informal caregivers with digital, multimedia training materials. Health professionals select these materials according to the needs of the homebound patients under the supervision of these caregivers. In turn, caregiver can then use their smartphones to consult and apply the care procedures illustrated by these materials. In this paper, we present the results of performed usability tests for both web and mobile software applications of the Help2Care platform. These indicate an overall positive outcome, revealing less usable aspects such as the navigation flow in the web application and some design elements in the mobile application. Important written feedback was also collected, which we took into consideration to improve the software features of the platform.

Noninvasive ventilation (NIV) is a technique for breathing support that significantly improves gas exchange and vital signs, reducing intubation and mortality rates. Helmets, unlike facemasks, allow for longer-term treatment and better ventilation, also being more cost-effective. As of today, we have found no reviews addressing this topic. This review aims to identify, map, and describe the characteristics of the use of noninvasive ventilation through helmet interface in critically ill COVID-19 adult patients hospitalized in acute care settings throughout the multiple moments that defined the COVID-19 pandemic. This scoping review will follow the methodology for scoping reviews proposed by JBI. A set of relevant electronic databases will be searched using terms such as COVID-19, helmet, and noninvasive ventilation. Two reviewers will independently perform the study selection regarding their eligibility. Data extraction will be accomplished using a researcher's developed tool considering the review questions. Findings will be presented in tables and a narrative description that aligns with the review's objective. This scoping review will consider any quantitative, qualitative, mixed-methods studies and systematic review designs for inclusion, focusing on the use of helmet on critically ill adult patients with COVID-19 hospitalized in acute care settings.
RESUMEN
Falls are a public health problem that cause serious damage to people's health and health systems. This study aims to estimate the validity and reliability of the Memorial Emergency Department Fall Risk Assessment Tool for the European Portuguese population. The sample included 186 adults from an emergency department of a District Hospital in Portugal. Reliability and precision (inter-rater reliability) are assessed by two independent raters. The relationship between MEDFRAT and the Morse Fall Risk Scale is evaluated. All items presented a high Kappa index. The MEDFRAT showed a high and significant correlation with the Morse Fall Risk Scale. The influence of sociodemographic and clinical data was also checked. The MEDFRAT is adequate, valid and reliable for the European Portuguese population to assess the risk of falling of emergency department patients.
RESUMEN
OBJECTIVES: to validate, for the Portuguese population, the Clinical Decision-Making Nursing Scale© (CDMNS©). METHODS: this methodological study involved 496 nursing students who filled in a questionnaire created using sociodemographic and academic data, and the scale to evaluate the making of decisions in nursing. RESULTS: the confirmatory factorial analysis showed that the adjustment of the factorial structure has good quality, being made up by three factors (X2/gl = 2.056; GFI = 0.927; CFI = 0.917; RMSEA = 0.046; RMR = 0.039; SRMR = 0.050). For the scale to be reliable, it had to include only the reliability of the scale required it to be constituted by 23 items, with correlation values that varied from 0.184 and 0.610, and a global Cronbach's Alpha of 0.851, which showed its good reliability. CONCLUSIONS: the CDMNS-PT© is valid and reliable, showing a high potential to be used in clinical practice and investigation.

OBJECTIVES: This systematic review aimed to understand the current state of the art about the effectiveness of mindfulness-based relapse prevention (MBRP) on individuals with substance use disorders (SUD), taking into account not only SUD variables (e.g., cravings, frequency of use) but also other relevant clinical variables (e.g., anxiety and depressive symptoms, quality of life). METHODS: A comprehensive search of electronic databases was conducted to identify studies that investigate MBRP interventions on individuals with SUD. Studies that met the inclusion criteria were synthesized and assessed using systematic review methods. RESULTS: Thirteen studies were included in the present review. The methodological quality of the included studies was moderately strong. Nine studies (69.2%) used the traditional 16 h MBRP program. Six studies (46.1%) chose to use a co-intervention treatment ranging from the treatment as usual (TAU) to cognitive behavioral therapy. All but one study indicated that their interventions produced positive effects on at least one addiction outcome measure. None of the interventions were evaluated across different settings or populations. CONCLUSIONS: Despite some heterogeneity regarding the type of MBRP program used, results support the effectiveness of these interventions in the SUD population, especially in reducing cravings, decreasing the frequency of use, and improving depressive symptoms.
RESUMEN
Concerns about weight and body image are common among adolescents since they are particularly vulnerable to body-image dissatisfaction due to the normal physiological, social, and psychological changes they are going through. This study aims to analyse the relationship between food choice motivations and physical activity in body-image perception among adolescents. Twelve to sixteen years old adolescents were recruited from three school districts. The Portuguese version of the Food Choices Questionnaire (FCQ) was used to assess food choice motivators, and the Quantification de l'Activité Physique en Altitude Chez les Enfants was used to assess physical activity and to calculate daily energy expenditure (DEE). Body image perception was measured using Collins' sequence of seven silhouettes. Body image (dis)satisfaction was estimated by the present body shape minus the desired body shape. ANOVA and Kruskal-Wallis tests were performed to compare groups, and the post-hoc Bonferroni test was used to compare target groups. A multinominal logistic regression was performed to analyse the association between gender, age, hours of sport's competition, FCQ, and body dissatisfaction. All analyses were performed in IBM SPSS Statistics 26.0. The sample comprised 286 adolescents (51.4% females). Means of FCQ categories varied between 0.33 and 0.97 (range: -2 to 2). Regarding the categories of FCQ, statistically significant differences were found in the category of body satisfaction and weight control among the three groups (p = 0.004). A preventive effect was found of choosing food regarding body satisfaction and weight control, on body-image dissatisfaction.
