Gerontological educational interventions for student nurses: a systematic review of qualitative findings.

OBJECTIVES: This systematic review of qualitative studies explored interventions to improve student nurses' knowledge, attitudes or willingness to work with older people. Student nurses are likely to encounter older people in all health and aged care settings, however, research demonstrates that few have career aspirations in gerontological nursing. METHODS: Qualitative systematic review method based on the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Search of Medline, Embase, PsycINFO, EBSCOhost and Scopus yielded 1841 articles which were screened to include primary research about educational interventions to improve student nurses' knowledge, attitudes and/or willingness to work with older people. Data extraction was performed on the 14 included studies, and data were analysed using directed content analysis. The Mixed Methods Appraisal Tool (MMAT) was used the assess the quality of the studies. CONCLUSIONS: Educational interventions included theory or practice courses, or a combination of theory and practice. While most interventions changed nursing students' negative attitudes towards older people, few increased their willingness to work with them. Practice courses had the most significant impact on willingness to work with older people. Quality assessment revealed methodical limitations. More research is needed to better understand the elements of practice interventions that enhance student nurses' knowledge, attitudes, and willingness to work with older people, so that they can be replicated.

Impact of Secondary Amenorrhea on Cardiovascular Disease Risk in Physically Active Women: A Systematic Review and Meta-Analysis.

BACKGROUND: Exercise-associated secondary amenorrhea results in estrogen deficiency, which may lead to dysfunction in estrogen's normal cardioprotective pathways. Estrogen may be essential in a woman's endothelial adaptations to exercise. The objective of this review was to assess the association between secondary amenorrhea in physically active women and cardiovascular disease (CVD) risk. METHODS AND RESULTS: A literature search was performed in January 2023 and updated in August 2023 of the Cumulative Index to Nursing and Allied Health Literature (EBSCOhost), Cochrane Library, Embase (Ovid), MEDLINE (Ovid), SPORTDiscus (EBSCOhost), and Scopus from inception to present with no date or language limitations. Citation chaining was done to screen for additional studies. Eight sources were searched for gray literature. Studies that compared physically active women with amenorrhea to physically active women with eumenorrhea aged 18 to 35 years with evidence of CVD, alterations to cardiovascular physiology, or CVD risks were included. Eighteen observational studies from 3 countries were included. Overall, the quality of evidence was good. A meta-analysis was performed. Physically active women with secondary amenorrhea had significantly lower estradiol, flow-mediated dilation, resting heart rate, systolic blood pressure, and diastolic blood pressure and higher total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein cholesterol. CONCLUSIONS: Estrogen deficiency resulting from exercise-associated secondary amenorrhea in physically active women may impact cardiovascular physiology and certain CVD risk factors. The research in this area is observational; therefore, findings should be interpreted cautiously. However, as exercise-associated secondary amenorrhea is reversible and the primary prevention of CVD is important for public health, it may be important to treat secondary amenorrhea and restore estrogen levels.

Challenges in ageing persons with haemophilia.

As treatments for individuals with inherited bleeding disorders improve, life expectancy increases and is approaching that of the normal population. Concomitant with this we are now seeing the problems of ageing in the bleeding disorder population. Although the clear-cut association between low clotting factor levels and risk of bleeding is well recognised, a relationship between high levels, some non-factor therapies and thrombotic risk also exists. The management of thrombosis in persons with inherited bleeding disorders is complex but manageable with modern treatments and collaboration in decision making between health care professionals and patients. Despite the improvements in treatment and reduction in bleeding, mostly musculoskeletal pain continues to be a major issue with advancing age. The management of pain amongst older people with haemophilia who may have multiple comorbidities should involve a person-centred, holistic, multi-disciplinary approach to support and optimise long-term physical functioning and overall quality of life.

Digital Knowledge Translation Tools for Disseminating Sexual and Reproductive Health Information to Adolescents: Protocol for an Evidence Gap Map Review.

BACKGROUND: Digital or eHealth knowledge translation (KT) interventions have been identified as useful public health tools, particularly to advance sexual and reproductive health (SRH) among adolescents. Existing literature reviews on digital health interventions for adolescents' SRH demonstrate limitations, including shortcomings in reporting and comprehensiveness that limit the utility and trustworthiness of findings. However, there is a lack of evidence synthesis on the effectiveness of available digital or mobile health KT tools to promote SRH interventions for adolescents. OBJECTIVE: We aim to identify, map, and describe existing empirical evidence on the digital KT tools developed to improve adolescent SRH outcomes globally. METHODS: This study will be conducted using an evidence gap map (EGM) approach to address the objectives, including reviewing relevant literature and a landscape analysis of the outcomes of interest. The following electronic databases will be searched for retrieval of literature: MEDLINE (1946-present), Embase (1974-present), and Global Health (1910-present) via OVID; CINAHL (1936-present) via EBSCOhost; Scopus (1976-present); and Cochrane Library (1993-present) via Wiley. We will include only those studies that focused on adolescents aged 10-19 years and addressed SRH outcomes. We will include experimental studies (randomized or cluster randomized and nonrandomized controlled trials, including quasi-randomized, controlled before-after, and interruptive time series) and observational studies, that is, including prospective cohort and case-control studies. The experimental and observational studies will only be included in the presence of control or comparison arms. Studies with a historical control arm will be excluded. The systematic review software, Covidence (Ventas Health Innovation), will be used to screen and select the studies. Further, 2 independent reviewers will complete the first and second levels of screening of studies and any conflicts arising will be resolved by consensus between the 2 reviewers or by involving the third reviewer. We will conduct the quality assessment of all included studies using the Risk of Bias tool for randomized controlled trials and nonrandomized controlled trials, and AMSTAR2 for systematic reviews. RESULTS: Papers screening, data extraction, and synthesis will be completed by March 2024. We will use EPPI-Mapper (The International Public Policy Observatory) software to generate an online evidence map and to produce the tables and figures for the descriptive report. This EGM review will identify areas with high-quality, evidence-based digital KT tools (for immediate scale and spread) and areas where few or no KT tools exist (for targeted KT tool development and research or policy prioritization). CONCLUSIONS: This protocol focused on mapping eHealth KT tools that have been used in the literature to address SRH among adolescents. This will be the first EGM exercise to map digital KT tools to promote adolescents' SRH and will incorporate a range of published sources.

Gerontological nursing competencies: A scoping review.

BACKGROUND: Despite decades of advocates striving to enhance gerontological content in baccalaureate nursing programs, nurses are still graduating with inadequate knowledge and skills to work with older adults. Scholars suggest that incorporating entry-to-practice gerontological competencies could be one way to improve graduating nurses' knowledge about older adults. AIM: To examine the state of gerontological entry to practice competencies and standards for baccalaureate-prepared nurses around the world. DESIGN: We conducted a scoping review of the literature using the Joanna Briggs Institute (JBI) framework and followed PRISMA-ScR guidelines to report findings. METHODS: We performed searches from inception to June 20th 2022 in Medline and EMBASE via OVID, CINAHL via EBSCOhost, Scopus, and Cochrane Library via Wiley. We conducted a search on GOOGLE for grey literature. We included literature that examined 1) baccalaureate nursing programs, 2) gerontological competencies/standards, and 3) older people/adults. RESULTS: We found 8 literature sources, 4 of which were academic papers and 4 documents describing gerontological entry-to-practice standards and competencies from national nursing associations. Gerontological competencies highlight providing person-centered care to older people and their families across many care contexts. This care includes relational and cultural competence, exhibiting professional values and screening for potential elder abuse. Scholars in two papers relayed their experiences incorporating gerontological competencies into their curricula and two studied student nurses' gerontological competency. CONCLUSIONS: There is interest and some progress in developing and incorporating gerontological competencies in various countries but not enough. A coordinated approach to sharing information and expertise among nations is needed to develop international gerontological competencies to facilitate improved nursing care with older adults.

Impact of secondary amenorrhea on cardiovascular disease risk in physically active women: a systematic review protocol.

OBJECTIVE: The objective of this review is to assess the association between secondary amenorrhea in physically active women and cardiovascular disease risk. INTRODUCTION: It is well established that a woman's risk of cardiovascular disease greatly increases after menopause. The sharp decline in estrogen is seen as a causal factor. Exercise-induced secondary amenorrhea results in estrogen deficiency, which may lead to dysfunction in estrogen's cardioprotective pathways. Further, estrogen may be essential in a woman's endothelial adaptations to exercise. The impact of secondary amenorrhea on cardiovascular disease risk in premenopausal women is not well established. INCLUSION CRITERIA: This review will consider studies that include physically active women experiencing amenorrhea in any country. Only studies that present evidence of cardiovascular disease, alterations to cardiovascular physiology, or data on cardiovascular risk factors (eg, lipid profile changes) will be considered. The review will consider experimental or observational epidemiological study designs. METHODS: Searches will be conducted in CINAHL (EBSCOhost), the Cochrane Library, Embase (Ovid), MEDLINE (Ovid), SPORTDiscus (EBSCOhost), and Scopus from inception to present with no date or language limitations. Two independent reviewers will screen titles, abstracts, and full texts, appraise methodological quality, and extract data from studies. Where possible, studies will be pooled in a statistical meta-analysis in addition to subgroup analyses. Where pooling is not possible, the findings will be presented in narrative format. Certainty of the evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. REVIEW REGISTRATION: PROSPERO CRD42023360781.

Synchronous Web-Based Psychotherapy for Mental Disorders From a Health Quality Perspective: Scoping Review.

BACKGROUND: The COVID-19 pandemic necessitated rapid changes to health care delivery, including a shift from in-person to digitally delivered psychotherapy. While these changes helped ensure timely psychotherapy provision, many concerns exist, including clinical, cultural, practical, privacy, and security issues. OBJECTIVE: This scoping review systematically mapped existing peer-reviewed research on synchronous, therapist-delivered web-based psychotherapy for individuals with a diagnosed mental illness. Data were analyzed through the lens of the Alberta Quality Matrix for Health (AQMH) to assess to what degree this literature addresses key indicators of health care quality. This analysis aided in the identification and organization of knowledge gaps with regard to web-based psychotherapies, highlighting potential disparities between previously prioritized dimensions of care and those requiring further attention. METHODS: This review adhered to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. We included peer-reviewed primary research studies in the English language investigating synchronous, therapist-delivered remote psychotherapy delivered to adults (aged 18 years and older) with a Diagnostic and Statistical Manual of Mental Disorders or International Statistical Classification of Diseases diagnosed mental illness. All other citations were excluded. Relevant studies were identified through MEDLINE, APA PsycINFO, Embase (OVID), Web of Science: Core Collection (Clarivate), Cochrane Library (Wiley), and Scopus (Elsevier) databases. Databases were searched on March 18, 2021. For every publication that was taken into consideration, the data were charted independently by 2 reviewers, and in the event of a discrepancy, the principal investigator validated the choice of either extractor. Results were thematically described according to the 6 AQMH dimensions: acceptability, accessibility, appropriateness, effectiveness, efficiency, and safety. RESULTS: From 13,209 publications, 48 articles were included, largely from North American studies. Most studies measured treatment effectiveness (n=48, 100%) and acceptability (n=29, 60%) health quality dimensions. Over 80% (40/48) of studies investigated either a cognitive or exposure intervention for either posttraumatic stress disorder or a mood or anxiety disorder, generally indicating comparable results to in-person therapy. Safety (n=5, 10%) was measured in fewer studies, while treatment accessibility, appropriateness, and efficiency were not explicitly measured in any study, although these dimensions were mentioned as a future direction, hypothesis, or potential outcome. CONCLUSIONS: In relation to web-based therapist-delivered psychotherapies for those with a diagnosed mental illness, important aspects of health care quality (accessibility, appropriateness, efficiency, and safety) have received little scientific examination, underscoring a need to address these gaps. There are also significant issues related to the generalizability of this literature, including the underrepresentation of many geographic regions, cultures, populations, clinical contexts, and psychotherapy modalities. Qualitative research in underrepresented populations and settings may uncover important patient and contextual factors important for the future implementation of quality web-based psychotherapy.

Dynamic genetic adaptation of Bacteroides thetaiotaomicron during murine gut colonization.

To understand how a bacterium ultimately succeeds or fails in adapting to a new host, it is essential to assess the temporal dynamics of its fitness over the course of colonization. Here, we introduce a human-derived commensal organism, Bacteroides thetaiotaomicron (Bt), into the guts of germ-free mice to determine whether and how the genetic requirements for colonization shift over time. Combining a high-throughput functional genetics assay and transcriptomics, we find that gene usage changes drastically during the first days of colonization, shifting from high expression of amino acid biosynthesis genes to broad upregulation of diverse polysaccharide utilization loci. Within the first week, metabolism becomes centered around utilization of a predominant dietary oligosaccharide, and these changes are largely sustained through 6 weeks of colonization. Spontaneous mutations in wild-type Bt also evolve around this locus. These findings highlight the importance of considering temporal colonization dynamics in developing more effective microbiome-based therapies.

Electronic harm reduction interventions for drug overdose monitoring and prevention: A scoping review.

BACKGROUND: Novel strategies are required to address rising overdose deaths across the globe. We sought to identify the breadth and depth of the existing evidence around electronic harm reduction (e-harm reduction) interventions that aimed to reduce the harms associated with substance use. METHODS: We conducted a scoping review according to the PRISMA-ScR and PRISMA for Searching guidelines. A health sciences librarian systematically searched seven health databases from inception until January 20, 2023. Citation chaining and reference lists of included studies were searched to identify additional articles. Two reviewers independently screened, extracted and charted the data. Additionally, we conducted a gray literature search and environmental scan to supplement the findings. RESULTS: A total of 51 studies met the criteria for inclusion (30 peer-reviewed articles and 21 non-peer reviewed). Most peer-reviewed studies were conducted in Western countries (USA = 23, Canada = 3, Europe = 3, China = 1) and among adult samples (adult = 27, youth/adults =1, unspecified = 2). Study designs were predominantly quantitative (n = 24), with a minority using qualitative (n = 4) or mixed methods (n = 2). Most e-harm reduction interventions were harm reduction (n = 15), followed by education (n = 6), treatment (n = 2), and combined/other approaches (n = 7). Interventions utilized web-based/mobile applications (n = 15), telephone/telehealth (n = 10), and other technology (n = 5). CONCLUSIONS: While e-harm reduction technology is promising, further research is required to establish the efficacy and effectiveness of these novel interventions.

Effectiveness of hospital-based strategies for improving childhood immunization coverage: A systematic review.

BACKGROUND: Hospital settings represent an opportunity to offer and/or promote childhood vaccination. The purpose of the systematic review was to assess the effectiveness of different hospital-based strategies for improving childhood vaccination coverage. METHODS: A systematic search of multiple bibliographic databases, thesis databases, and relevant websites was conducted to identify peer-reviewed articles published up to September 20, 2021. Articles were included if they evaluated the impact of a hospital (inpatient or emergency department)-based intervention on childhood vaccination coverage, were published in English or French, and were conducted in high-income countries. High quality studies were included in a narrative synthesis. RESULTS: We included 25 high quality studies out of 7,845 unique citations. Studies focused on routine, outbreak, and influenza vaccines, and interventions included opportunistic vaccination (i.e. vaccination during hospital visit) (n = 7), patient education (n = 2), community connection (n = 2), patient reminders (n = 2), and opportunistic vaccination combined with patient education and/or reminders (n = 12). Opportunistic vaccination interventions were generally successful at improving vaccine coverage, though results ranged from no impact to vaccinating 71 % of eligible children with routine vaccines and 9-61 % of eligible children with influenza vaccines. Interventions that aimed to increase vaccination after hospital discharge (community connection, patient education, reminders) were less successful. CONCLUSIONS: Some interventions that provide vaccination to children accessing hospitals improved vaccine coverage; however, the baseline coverage level of the population, as well as implementation strategies used impact success. There is limited evidence that interventions promoting vaccination after hospital discharge are more successful if they are tailored to the individual.

Diverse organic-mineral associations in Jezero crater, Mars.

The presence and distribution of preserved organic matter on the surface of Mars can provide key information about the Martian carbon cycle and the potential of the planet to host life throughout its history. Several types of organic molecules have been previously detected in Martian meteorites1 and at Gale crater, Mars2-4. Evaluating the diversity and detectability of organic matter elsewhere on Mars is important for understanding the extent and diversity of Martian surface processes and the potential availability of carbon sources1,5,6. Here we report the detection of Raman and fluorescence spectra consistent with several species of aromatic organic molecules in the Máaz and Séítah formations within the Crater Floor sequences of Jezero crater, Mars. We report specific fluorescence-mineral associations consistent with many classes of organic molecules occurring in different spatial patterns within these compositionally distinct formations, potentially indicating different fates of carbon across environments. Our findings suggest there may be a diversity of aromatic molecules prevalent on the Martian surface, and these materials persist despite exposure to surface conditions. These potential organic molecules are largely found within minerals linked to aqueous processes, indicating that these processes may have had a key role in organic synthesis, transport or preservation.

Psychosocial interventions and mental health in patients with cardiovascular diseases living in low- and middle-income countries: A systematic review and meta-analysis.

OBJECTIVE: Mental health issues are closely associated with symptoms and outcomes of cardiovascular diseases (CVDs). The magnitude of this problem is alarmingly high in low and middle-income countries (LMICs). This systematic review and meta-analysis aimed to examine the effectiveness of psychosocial interventions on mental health outcomes among patients with CVDs living in LMICs. METHODS: This review includes Randomized controlled trials (RCTs) and quasi-experimental studies conducted on adult patients who had a CVD and/or hypertension and located in LMICs. Studies published in English between 2010 and March, 2021 and which primarily reported mental health outcomes of resilience, self-efficacy, Quality of life (QoL), depression and anxiety were included. Studies were screened, extracted and critically appraised by two independent reviewers. Meta-analysis was conducted for RCTs and narrative summaries were conducted for all other studies. PRISMA guidelines were followed for reporting review methods and findings. RESULTS: 109 studies included in this review reported educational, nursing, behavioral and psychological, spiritual, relaxation, and mindfulness interventions provided by multidisciplinary teams. 14 studies reported self-efficacy, 70 reported QoL, 62 reported one or both of anxiety and depression, and no study was found that reported resilience as an outcome in this population. Pooled analysis showed improvements in self-efficacy and QoL outcomes. The majority of studies showed improvement in outcomes, though the quality of the included studies varied. CONCLUSION: Patients with CVDs in LMICs may experience improved mental health through the use of diverse psychosocial interventions. Evaluations are needed to investigate whether the impact of interventions on mental health are sustained over time.

Effectiveness of telerehabilitation and home-based falls prevention programs for community-dwelling older adults: a systematic review and meta-analysis protocol.

INTRODUCTION: Falls among older adults are associated with adverse sequelae including fractures, chronic pain and disability, which can lead to loss of independence and increased risks of nursing home admissions. The COVID-19 pandemic has significantly increased the uptake of telehealth, but the effectiveness of virtual, home-based fall prevention programmes is not clearly known. We aim to synthesise the trials on telerehabilitation and home-based falls prevention programmes to determine their effectiveness in reducing falls and adverse outcomes, as well as to describe the safety risks associated with telerehabilitation. METHODS AND ANALYSIS: This protocol was developed using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Database searches from inception to August 2022 will be conducted without language restrictions of MEDLINE, EMBASE, Ovid HealthSTAR, CINAHL, SPORTDiscus, Physiotherapy EvidenceDatabase (PEDro) and the Cochrane Library. Grey literature including major geriatrics conference proceedings will be reviewed. Using Covidence software, two independent reviewers will in duplicate determine the eligibility of randomised controlled trials (RCTs). Eligible RCTs will compare telerehabilitation and home-based fall prevention programmes to usual care among community-dwelling older adults and will report at least one efficacy outcome: falls, fractures, hospitalisations, mortality or quality of life; or at least one safety outcome: pain, myalgias, dyspnoea, syncope or fatigue. Secondary outcomes include functional performance in activities of daily living, balance and endurance. Risk of bias will be assessed using the Cochrane Collaboration tool. DerSimonian-Laird random effects models will be used for the meta-analysis. Heterogeneity will be assessed using the I2 statistic and Cochran's Q statistic. We will assess publication bias using the Egger's test. Prespecified subgroup analyses and univariate meta-regression will be used. ETHICS AND DISSEMINATION: Ethics approval is not required. The results will be disseminated through peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42022356759.

A cross-sectional follow-up study of physical activity in adults with moderate and severe haemophilia.

AIM: To conduct a cross-sectional follow-up assessment of physical activity (PA) in people with moderate and severe haemophilia (PwMSH) from the Irish Personalised Approach to the Treatment of Haemophilia (iPATH) study. METHODS: Between June-December 2021, participants' PA was measured over one week using accelerometery, and was compared with their previously measured data from the original iPATH assessment. Self-awareness of PA and the impact of the Covid-19 pandemic on PA, pain, mobility and function were retrospectively examined using a survey. RESULTS: Of 30 participants who returned surveys [n = 19, severe (FVIII, <.01 IU/mL); n = 4, moderate (FVIII, .01-.05 IU/mL); n = 7, severe (FIX, <.01 IU/mL); age: 47 (36, 55) years], 28 completed accelerometery (follow-up time: 3 years). There were no significant differences in accelerometer PA (all p > .05), but achievement of World Health Organisation guidelines increased (67.9%-75.0%; p = .646). Increased self-awareness of PA was reported by 76.7%, and 66.7% reported desires to become more physically active. Compared to normal, most reported either no differences or lower levels of PA during lockdown restrictions. Self-reported PA increased for most when restrictions eased from April 2021 onwards. Beyond the pandemic, concerns included pain and access to exercise resources. CONCLUSION: Self-reported PA throughout the pandemic was variable, whilst there were no significant differences in objectively measured PA between assessment periods, despite reports of increased self-awareness and desires to be physically active at follow-up. Further qualitative research is needed to design personalised PA and health interventions, capturing perspectives of patients, their families, and multi-disciplinary haemophilia healthcare providers.

Racism in Health Services for Adolescents: A Scoping Review.

Addressing racism within health systems and services is critical to addressing health vulnerabilities and promoting health equity for racialized populations. Currently, there is limited knowledge about the ways in which racism affects health services for adolescents. A scoping review was undertaken following the Joanna Briggs Institute Manual for Evidence Synthesis methodology and guided by the research questions: (1) What are the characteristics of the literature examining racism in health service use for adolescents? (2) What are the foci of the literature on systemic racism and health services for adolescents? A systematic literature search was conducted in April 2021 to identify all relevant published studies. The search identified 3049 unique articles, with a total of 13 articles included in this review. Multiple levels of racism were examined in the included articles across various health care settings. Five foci were identified: racism prevention, missed care, quality of care, racial bias, and experiences of racism. Our review indicates a current emphasis on interpersonal racism within this field of study, with emergent discussion of the impact of systemic racism. However, greater attention is needed that would investigate multiple forms of racism (institutional, interpersonal, internalized) in relation to specific contexts and adolescent populations.

An Umbrella Review of the Best and Most Up-to-Date Evidence on the Built Environment and Physical Activity in Older Adults ≥60 Years.

Objectives: To present the best and most up-to-date evidence on associations between built environment (BE) attributes and overall and specific domains of physical activity (PA) (i.e., leisure, transport, walking, and cycling) in older adults (≥60 years). Methods: An umbrella review was undertaken to compile evidence from systematic reviews using the Joanna Briggs Institute methodology. A comprehensive search (updated 16 August 2022), inclusion/exclusion of articles via title/abstract and full-text reviews, data extraction, and critical appraisal were completed. Only reviews with a good critical appraisal score were included. Results: Across three included systematic reviews, each BE attribute category was positively associated with ≥1 PA outcome. A larger number of significant associations with BE attributes were reported for transport walking (13/26), total walking (10/25), and total PA (9/26), compared to leisure walking (4/34) and transport cycling (3/12). Fewer associations have been examined for leisure cycling (1/2). Conclusion: Although the causality of findings cannot be concluded due to most primary studies being cross-sectional, these best and most up-to-date findings can guide necessary future longitudinal and experimental studies for the (re)design of age-friendly communities.

Digital health education and training for undergraduate and graduate nursing students: a scoping review protocol.

OBJECTIVE: The objective of this review is to collate and analyze literature reporting on digital health education and training courses, or other pedagogical interventions, for nursing students at the undergraduate and graduate level to identify gaps and inform the development of future educational interventions. INTRODUCTION: In this era of technology-driven health care, upskilling and/or reskilling the nursing workforce is urgently needed for nurses to lead the digital health future and improve patient care. While informatics competency frameworks serve to inform nursing education and practice, they do not address the entire digital health spectrum. INCLUSION CRITERIA: This review will include research studies, theoretical/discussion papers, and reports, as well as gray literature from relevant sources published in the last 10 years. Opinion pieces, editorials, conference proceedings, and papers published in languages other than English will be excluded. METHODS: The JBI methodology for scoping reviews will be followed. Searches will be conducted in Embase, CINAHL, ERIC, MEDLINE, Scopus, and Education Research Complete to retrieve potentially relevant studies. Hand searches of reference lists of included studies will be conducted. Two reviewers will independently screen records against predefined eligibility criteria and consult a third reviewer if conflicts arise. Decisions will be documented using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram. Quantitative data will be analyzed using descriptive statistics. Content analysis will be applied to qualitative data to identify categories and themes. Findings will be synthesized and reported in tables and narrative format. REVIEW REGISTRATION NUMBER: Open Science Framework osf.io/42eug.

Heterogeneity in the half-life of factor VIII concentrate in patients with hemophilia A is due to variability in the clearance of endogenous von Willebrand factor.

BACKGROUND: Previous studies have reported marked interindividual variation in factor VIII (FVIII) clearance in patients with hemophilia (PWH) and proposed a number of factors that influence this heterogeneity. OBJECTIVES: To investigate the importance of the clearance rates of endogenous von Willebrand factor (VWF) compared with those of other FVIII half-life modifiers in adult PWH. METHODS: The half-life of recombinant FVIII was determined in a cohort of 61 adult PWH. A range of reported modifiers of FVIII clearance was assessed (including plasma VWF:antigen and VWF propeptide levels; VWF-FVIII binding capacity; ABO blood group; and nonneutralizing anti-FVIII antibodies). The FVIII-binding region of the VWF gene was sequenced. Finally, the effects of variation in FVIII half-life on clinical phenotype were investigated. RESULTS: We demonstrated that heterogeneity in the clearance of endogenous plasma VWF is a key determinant of variable FVIII half-life in PWH. Both ABO blood group and age significantly impact FVIII clearance. The effect of ABO blood group on FVIII half-life in PWH is modulated entirely through its effect on the clearance rates of endogenous VWF. In contrast, the age-related effect on FVIII clearance is, at least in part, VWF independent. In contrast to previous studies, no major effects of variation in VWF-FVIII binding affinity on FVIII clearance were observed. Although high-titer immunoglobulin G antibodies (≥1:80) were observed in 26% of PWH, these did not impact FVIII half-life. Importantly, the annual FVIII usage (IU/kg/y) was significantly (p = .0035) increased in patients with an FVIII half-life of <12 hours. CONCLUSION: Our data demonstrate that heterogeneity in the half-life of FVIII concentrates in patients with hemophilia A is primarily attributable to variability in the clearance of endogenous VWF.

A Scoping Review on Community-Based Programs to Promote Physical Activity in Older Immigrants.

Older immigrants are at higher risks for inactivity due to cultural, environmental, and social barriers in the postmigration context. Community-based physical activity (PA) programs increase PA in older adults, yet little is known about approaches that specifically target older immigrants. This scoping review explores the literature on community-based programs that increase PA and physical fitness in immigrant older adults and identifies barriers and facilitators to PA program participation in this population. A systematic search of electronic databases and gray literature was conducted, and a total of 11 articles met the inclusion criteria after full-text screening. A range of populations and PA program characteristics are described, yet there is a lack of studies on older immigrant men, Black older immigrants, and immigrants from Arab and African countries. There is a need for further research to develop evidence-informed PA programs for this diverse population.
