Effectiveness of Caregiver-Provided Individual Cognitive Interventions in Older Adults with Dementia.

Background: In a society increasingly committed to promoting an active life in the community, new resources are needed to respond to the needs of citizens with Alzheimer's disease and other forms of dementia. The potential of several individual cognitive interventions to be provided by caregivers has been explored in the literature. Objective: To synthesize the best available evidence on the effectiveness of caregiver-provided individual cognitive interventions in older adults with dementia. Methods: Systematic review of experimental studies on individual cognitive interventions for older adults with dementia. An initial search of MEDLINE and CINAHL was undertaken. Another search for published and unpublished studies was performed on major healthcare-related online databases in March 2018 and updated in August 2022. This review considered studies that included older adults with dementia, aged 60 years and over. All studies that met the inclusion criteria were assessed for methodological quality using a JBI standardized critical appraisal checklist. Data were extracted using a JBI data extraction form for experimental studies. Results: Eleven studies were included: eight randomized controlled trials and three quasi-experimental studies. Caregiver-provided individual cognitive interventions had several beneficial effects in cognitive domains, including memory, verbal fluency, attention, problem-solving, and autonomy in activities of daily living. Conclusion: These interventions were associated with moderate improvements in cognitive performance and benefits in activities of daily living. The findings highlight the potential of caregiver-provided individual cognitive interventions for older adults with dementia.

Difficulties in Caring for the Older Adults: Perspective of Brazilian and Portuguese Caregivers.

This study aims to understand the difficulties in caring for the older adults with functional dependence from the perspective of Brazilian and Portuguese caregivers. This is a study based on the Theory of Social Representations, based on the Thematic Content Analysis proposed by Bardin, carried out with 21 informal caregivers of older adults in Brazil and 11 informal caregivers of older adults in Portugal. The instrument consisted of a questionnaire with sociodemographic data and data on health conditions along with an open interview with guiding questions on the theme of care. Data were analyzed using the Content Analysis technique proposed by Bardin, with the help of the QRS NVivo® Version 11 software (QSR International, Burlington, MA, USA). Three categories emerged from the speeches: "Caregiver burden", "Caregiver support network" and "Older adults resistance". The main difficulties mentioned by caregivers were associated with family articulation in meeting the needs of their older adults, whether due to the excessive demand of tasks, which results in overloading the caregiver, or the behaviors of the older adults themselves, or even the availability of a truly supportive and effective network.

Nursing Professional Self-Concept: A Scoping Review Protocol.

Nurses are considered one of the largest professional groups in healthcare, generating positive health outcomes for people at various stages of life. A significant impact on the construction of the professional self-or professional self-concept-is considered to exist through the educational process, influenced by factors such as the family and societal expectations often presented by teachers, tutors, and peers. Improving professional self-concept in nursing can offer specific gains in personal, relational, social, and interpersonal communication skills, favoring evolution in the academic and clinical path. This scoping review aims to map the literature related to the state of knowledge regarding professional self-concept in nursing. This scoping review will follow JBI recommendations with the PCC mnemonic and report its findings through PRISMA-ScR using a specific instrument made by the researchers. Providing healthcare complying with high scientific standards requires the professional to have enough self-confidence in his work and skills. The explicit acknowledgement of professional self-concept is essential for any educational tutor or experienced mentor to promote mental health and academic and professional performance.

eHealth Platforms to Promote Autonomous Life and Active Aging: A Scoping Review.

New technologies, namely eHealth platforms, are being used more than ever before. These platforms enable older people to have a more independent lifestyle, enhance their participation, and improve their well-being. Information and communication technologies are expected to be linked to the triad of aging, social inclusion, and active participation, which is in line with the implementation of Smart Healthy and Age-Friendly Environments. This scoping review aimed to map eHealth platforms designed to promote autonomous life and active aging. The Joanna Briggs Institute methodology and the PRISMA-ScR checklist were used. A search was conducted on MEDLINE (via PubMed), CINAHL Complete (via EBSCOhost), Scopus, Cochrane Database of Systematic Reviews (via EBSCOhost), SciELO, DART-Europe, CAPES, and MedNar databases. Fourteen studies were included. This scoping review synthesized information on eHealth platforms designed to promote active living, their domains of intervention, and the outcomes assessed in those studies that have implemented and evaluated these eHealth platforms.

Trends in Telecare Use among Community-Dwelling Older Adults: A Scoping Review.

A scoping review was conducted to map and analyze the concept of telecare services and the trends in telecare use. This scoping review was conducted according to Arksey and O'Malley's framework. A search was conducted in CINAHL (via EBSCO), ERIC, Academic Search Ultimate, and MEDLINE/PubMed databases. This scoping review considered quantitative (e.g., analytical observational studies, including prospective and retrospective cohort studies, case-control, analytical cross-sectional, and descriptive-observational studies), qualitative (e.g., phenomenology, grounded theory, ethnography, and action research), and mixed-method primary studies. Forty research articles published from 1 January 2012, to 1 January 2022 were included in this review, these studies met the eligibility criteria as all were focused on telecare and targeting older adults over 65 living at home. The reviewers coded the data in an Excel spreadsheet, including the articles' title, year, author, journal information and subject, research methods, sample size, location, and summary. Then, the researchers analyzed the conceptual definitions, measurement techniques, and findings in detail and the findings were grouped into categories. The trends around the concept of telecare are independent living, remote care, aging in place, and safety. Telecare research focuses mainly on service use, chronic illness, ethics, and cost-effectiveness. Technology acceptance among older individuals is a critical factor for telecare use. The results found in the literature about the cost-effectiveness of telecare are inconsistent.

Intergenerationality Programs-Between Children and Older Adults-For Portuguese Population: A Scoping Review.

The aging process is characterized by diverse and complex changes in the individual's various dimensions, requiring continuous adaptation. In this sense, this transition can be faced from an active aging standpoint through strategies such as intergenerationality programs/projects, resulting in an active social participation and valorization that is so important to life in society. This review aimed to map existing programs/projects to promote interaction between children and older adults in Portugal to understand the extent and type of evidence available. A scoping review was developed guided by the JBI methodology and using PRISMA-ScR. The studies included six programs/projects promoting intergenerationality identified in Portugal, focusing their actions on promoting active aging and preventing problems associated with aging. The evaluated dimensions along the implementation of these programs were in the cognitive, motor, emotional and communicational domains, including parameters such as self-esteem, self-confidence, self-worth, well-being, loneliness and depression. These programs/projects present themselves as potential senior mental health promoters. However, other dimensions have been evaluated during these programs'/projects' applications.

Imidazole Processing of Wheat Straw and Eucalyptus Residues-Comparison of Pre-Treatment Conditions and Their Influence on Enzymatic Hydrolysis.

Biomass pre-treatment is a key step in achieving the economic competitiveness of biomass conversion. In the present work, an imidazole pre-treatment process was performed and evaluated using wheat straw and eucalyptus residues as model feedstocks for agriculture and forest-origin biomasses, respectively. Results showed that imidazole is an efficient pre-treatment agent; however, better results were obtained for wheat straw due to the recalcitrant behavior of eucalyptus residues. The temperature had a stronger effect than time on wheat straw pre-treatment but at 160 °C and 4 h, similar results were obtained for cellulose and hemicellulose content from both biomasses (ca. 54% and 24%, respectively). Lignin content in the pre-treated solid was higher for eucalyptus residues (16% vs. 4%), as expected. Enzymatic hydrolysis, applied to both biomasses after different pre-treatments, revealed that results improved with increasing temperature/time for wheat straw. However, these conditions had no influence on the results for eucalyptus residues, with very low glucan to glucose enzymatic hydrolysis yield (93% for wheat straw vs. 40% for eucalyptus residues). Imidazole can therefore be considered as a suitable solvent for herbaceous biomass pre-treatment.

The Effect of the Chemical Character of Ionic Liquids on Biomass Pre-Treatment and Posterior Enzymatic Hydrolysis.

Ionic liquids have been recognised as interesting solvents applicable in efficient lignocellulosic biomass valorisation, especially in biomass fractionation into individual polymeric components or direct hydrolysis of some biomass fractions. Considering the chemical character of ionic liquids, two different approaches paved the way for the fractionation of biomass. The first strategy integrated a pre-treatment, hydrolysis and conversion of biomass through the employment of hydrogen-bond acidic 1-ethyl-3-methyimidazolim hydrogen sulphate ionic liquid. The second strategy relied on the use of a three-step fractionation process with hydrogen-bond basic 1-ethyl-3-methylimidazolium acetate to produce high purity cellulose, hemicellulose and lignin fractions. The proposed approaches were scrutinised for wheat straw and eucalyptus residues. These different biomasses enabled an understanding that enzymatic hydrolysis yields are dependent on the crystallinity of the pre-treated biomass. The use of acetate based ionic liquid allowed crystalline cellulose I to change to cellulose II and consequently enhanced the glucan to glucose yield to 93.1 ± 4.1 mol% and 82.9 ± 1.2 mol% for wheat straw and eucalyptus, respectively. However, for hydrogen sulphate ionic liquid, the same enzymatic hydrolysis yields were 61.6 ± 0.2 mol% for wheat straw and only 7.9 ± 0.3 mol% for eucalyptus residues. These results demonstrate the importance of both ionic liquid character and biomass type for efficient biomass processing.
