Original Research: Nurses' Knowledge and Attitudes Regarding the Sustainable Development Goals: A Global Study.

BACKGROUND: Nurses have a critical role to play in achieving the United Nations' 17 Sustainable Development Goals (SDGs). While Goal 3 (good health and well-being) is of particular importance to nursing, every SDG contributes to the advancement of universal health and well-being. Yet many nurses are unfamiliar with the SDGs and how they relate to everyday nursing practices. PURPOSE: The purpose of this study was to examine RNs' knowledge of and attitudes toward the SDGs. METHODS: This study used a descriptive correlational cross-sectional design. A convenience sample of RNs from multiple countries completed an anonymous online survey that included eight demographic items and 25 items exploring participants' knowledge of and attitudes toward the SDGs. Descriptive, parametric, and nonparametric statistics were used to analyze the data. RESULTS: The majority of nurses in this study perceived themselves as lacking knowledge of the SDGs. Most wanted to know more, including how they could take action to help achieve the goals. Overall, participants agreed that the SDGs are relevant to nursing practice and that nurses are integral to their advancement. Participants who were younger than age 50, those living in the United States, and those who practiced primarily in a clinical or community setting were more likely than others to self-report lower SDG knowledge scores. CONCLUSIONS: The study findings contribute to our collective understanding of RNs' knowledge and attitudes regarding the SDGs. They can assist nurse educators and leaders worldwide in developing targeted strategies to better inform nurses and prepare them for actions that will advance these goals. Increasing nurses' knowledge of the SDGs, especially as these goals relate to daily clinical practice, may lead to greater nursing engagement and impact.

Professional regulation in the digital era: A qualitative case study of three professions in Ontario, Canada.

Technology is transforming service delivery and practice in many regulated professions, altering required skills, scopes of practice, and the organization of professional work. Professional regulators face considerable pressure to facilitate technology-enabled work while adapting to digital changes in their practices and procedures. However, our understanding of how regulators are responding to technology-driven risks and the impact of technology on regulatory policy is limited. To examine the impact of technology and digitalization on regulation, we conducted an exploratory case study of the regulatory bodies for nursing, law, and social work in Ontario, Canada. Data were collected over two phases. First, we collected documents from the regulators' websites and regulatory consortiums. Second, we conducted key informant interviews with two representatives from each regulator. Data were thematically analyzed to explore the impact of technological change on regulatory activities and policies and to compare how regulatory structure and field shape this impact. Five themes were identified in our analysis: balancing efficiency potential with risks of certain technological advances; the potential for improving regulation through data analytics; considering how to regulate a technologically competent workforce; recalibrating pandemic emergency measures involving technology; and contemplating the future of technology on regulatory policy and practice. Regulators face ongoing challenges with providing equity-based approaches to regulating virtual practice, ensuring practitioners are technologically competent, and leveraging regulatory data to inform decision-making. Policymakers and regulators across Canada and internationally should prioritize risk-balanced policies, guidelines, and practice standards to support professional practice in the digital era.

Developing Policy Infrastructure to Guide Genomics-Informed Oncology Nursing in Canada: An Interpretive Descriptive Study.

BACKGROUND: Genomic technologies such as genetic testing and precision treatments are rapidly becoming routine in oncology care, and nurses play an increasingly important role in supporting the growing demands for genomics-informed healthcare. Policy infrastructure such as competencies, standards, scope of practice statements, and education and curriculum frameworks are urgently needed to guide these practice and education changes. PURPOSE: This study is part of a larger three-phase project to develop recommendations and catalyze action for genomics-informed oncology nursing education and practice for the Canadian Association of Nurses in Oncology and the Canadian Association of Schools of Nursing. This phase aimed to enhance understanding of policy needs and action drivers for genomics-informed oncology nursing education and practice through the perspectives of Canadian oncology nurses and patient partners. METHODS: Interpretive description methodology guided the study. Twenty semi-structured virtual interviews were conducted; 17 with oncology nurses in various domains of practice, and three with patient partner representatives. Data collection and analysis occurred concurrently. RESULTS: Our analysis identified three themes: 1) nurses and patients recognize that it is time for action, 2) nurses and patients see advantages to executing intentional, strategic, and collaborative policy development, and 3) leadership and advocacy are required to drive action. CONCLUSION: Nursing policy infrastructure is required to increase genomic literacy, support nurses in providing safe patient care, and establish clear roles, responsibilities, and accountabilities within the interdisciplinary team. Strong leadership and advocacy at the practice, organizational, and systems levels are vital to accelerating action.

Integrating genomics into Canadian oncology nursing policy: Insights from a comparative policy analysis.

AIM: To learn from two jurisdictions with mature genomics-informed nursing policy infrastructure-the United States (US) and the United Kingdom (UK)-to inform policy development for genomics-informed oncology nursing practice and education in Canada. DESIGN: Comparative document and policy analysis drawing on the 3i + E framework. METHODS: We drew on the principles of a rapid review and identified academic literature, grey literature and nursing policy documents through a systematic search of two databases, a website search of national genomics nursing and oncology nursing organizations in the US and UK, and recommendations from subject matter experts on an international advisory committee. A total of 94 documents informed our analysis. RESULTS: We found several types of policy documents guiding genomics-informed nursing practice and education in the US and UK. These included position statements, policy advocacy briefs, competencies, scope and standards of practice and education and curriculum frameworks. Examples of drivers that influenced policy development included nurses' values in aligning with evidence and meeting public expectations, strong nurse leaders, policy networks and shifting healthcare and policy landscapes. CONCLUSION: Our analysis of nursing policy infrastructure in the US and UK provides a framework to guide policy recommendations to accelerate the integration of genomics into Canadian oncology nursing practice and education. IMPLICATIONS FOR THE PROFESSION: Findings can assist Canadian oncology nurses in developing nursing policy infrastructure that supports full participation in safe and equitable genomics-informed oncology nursing practice and education within an interprofessional context. IMPACT: This study informs Canadian policy development for genomics-informed oncology nursing education and practice. The experiences of other countries demonstrate that change is incremental, and investment from strong advocates and collaborators can accelerate the integration of genomics into nursing. Though this research focuses on oncology nursing, it may also inform other nursing practice contexts influenced by genomics.

Genomics-informed nursing strategies and health equity: A scoping review protocol.

OBJECTIVE: The objective of this scoping review is to map the available evidence on strategies that nurses can use to facilitate genomics-informed healthcare to address health disparities. INTRODUCTION: Advancements in genomics over the last two decades have led to an increase in the delivery of genomics-informed health care. Although the integration of genomics into health care services continues to enhance patient outcomes, access to genomic technologies is not equitable, exacerbating existing health disparities amongst certain populations. As the largest portion of the health workforce, nurses play a critical role in the delivery of equitable genomics-informed care. However, little is known about how nurses can help address health disparities within the context of genomics-informed health care. A review of the literature will provide the necessary foundation to identify promising practices, policy, and knowledge gaps for further areas of inquiry. INCLUSION CRITERIA: We will include papers that explore strategies that nurses can undertake to facilitate genomics-informed care to address health disparities. METHODS: This review will be conducted using JBI methodology for scoping reviews. We will search electronic databases including MEDLINE (OVID), EMBASE, Cochrane Library, PsychInfo, and CINAHL for quantitative and qualitative studies, systematic reviews and grey literature. Theses, books, and unavailable full-text papers will be excluded. The search will be limited to papers from 2013 and beyond. Two reviewers will screen titles and abstracts followed by full-text and disagreements will be resolved by a third reviewer. We will use a data extraction tool using Microsoft Excel and analyse data using descriptive statistics and conventional content analysis. Findings will be presented in the form of evidence tables and a narrative summary. We will report findings using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). DISCUSSION: Genomics will continue to transform all aspects of health care across the wellness continuum from prevention, assessment, diagnosis, management, treatment, and palliative care. The identification of nursing strategies to address health disparities will build the foundation for policy and practice to ensure that the integration of genomic technologies benefits everyone.

Increasing the Visibility and Influence of Canadian Nurses within the United Nations System.

Founded in 1945, the United Nations (UN) system has become the place where countries come together to discuss complex and multifaceted issues that no one country can tackle alone. Civil society continues to be an integral part of the UN system, supporting the work of various entities and providing expertise on core pillars such as development, human rights and peace and security. Some global nursing leaders have made considerable progress in increasing nursing engagement and visibility across the system; however, representation remains small. Despite a strong appetite to be involved in global public policy, there is also a need to increase awareness and knowledge of how to engage with and navigate key global organizations. Numerous opportunities exist for civil society to participate in, learn from and influence the work of the UN. This article provides Canadian nursing leaders with examples of pathways to explore to become formally affiliated with entities within the UN system.

Disrupted Structural White Matter Network in Alzheimer's Disease Continuum, Vascular Dementia, and Mixed Dementia: A Diffusion Tensor Imaging Study.

BACKGROUND: Dementia presents a significant burden to patients and healthcare systems worldwide. Early and accurate diagnosis, as well as differential diagnosis of various types of dementia, are crucial for timely intervention and management. However, there is currently a lack of clinical tools for accurately distinguishing between these types. OBJECTIVE: This study aimed to investigate the differences in the structural white matter (WM) network among different types of cognitive impairment/dementia using diffusion tensor imaging, and to explore the clinical relevance of the structural network. METHODS: A total of 21 normal control, 13 subjective cognitive decline (SCD), 40 mild cognitive impairment (MCI), 22 Alzheimer's disease (AD), 13 mixed dementia (MixD), and 17 vascular dementia (VaD) participants were recruited. Graph theory was utilized to construct the brain network. RESULTS: Our findings revealed a monotonic trend of disruption in the brain WM network (VaD > MixD > AD > MCI > SCD) in terms of decreased global efficiency, local efficiency, and average clustering coefficient, as well as increased characteristic path length. These network measurements were significantly associated with the clinical cognition index in each disease group separately. CONCLUSION: These findings suggest that structural WM network measurements can be utilized to differentiate between different types of cognitive impairment/dementia, and these measurements can provide valuable cognition-related information.

The Use of Diffusion Kurtosis Imaging for the Differential Diagnosis of Alzheimer's Disease Spectrum.

Structural and diffusion kurtosis imaging (DKI) can be used to assess hippocampal macrostructural and microstructural alterations respectively, in Alzheimer's disease (AD) spectrum, spanning from subjective cognitive decline (SCD) to mild cognitive impairment (MCI) and AD. In this study, we explored the diagnostic performance of structural imaging and DKI of the hippocampus in the AD spectrum. Eleven SCD, thirty-seven MCI, sixteen AD, and nineteen age- and sex-matched normal controls (NCs) were included. Bilateral hippocampal volume, mean diffusivity (MD), and mean kurtosis (MK) were obtained. We detected that in AD vs. NCs, the right hippocampal volume showed the most prominent AUC value (AUC = 0.977); in MCI vs. NCs, the right hippocampal MD was the most sensitive discriminator (AUC = 0.819); in SCD vs. NCs, the left hippocampal MK was the most sensitive biomarker (AUC = 0.775). These findings suggest that, in the predementia stage (SCD and MCI), hippocampal microstructural changes are predominant, and the best discriminators are microstructural measurements (left hippocampal MK for SCD and right hippocampal MD for MCI); while in the dementia stage (AD), hippocampal macrostructural alterations are superior, and the best indicator is the macrostructural index (right hippocampal volume).

Lessons from professional nursing associations' policy advocacy responses to the COVID-19 pandemic: An interpretive description.

BACKGROUND: Professional nursing associations across jurisdictions engaged in significant policy advocacy during the COVID-19 pandemic to support nurses, the public and health systems. While professional nursing associations have a long history of engaging in policy advocacy, scholars have rarely critically examined this important function. PURPOSE: The purpose of this study was twofold: (a) to examine how professional nursing associations engage in the process of policy advocacy and (b) to develop knowledge specific to policy advocacy in the context of a global pandemic. METHODS: This study was conducted using interpretive description. A total of eight individuals from four professional nursing associations (two local, one national and one international) participated. Data sources included semi-structured interviews conducted between October 2021 and December 2021 and internal and external documents produced by organizations. Data collection and analysis occurred concurrently. Within-case analysis was conducted prior to cross-case comparisons. FINDINGS: Six key themes were developed to illustrate the lessons learned from these organizations including their organization's role in supporting a wide audience (professional nursing associations as a compass); the scope of their policy priorities (bridging the gaps between issues and solutions), the breadth of their advocacy strategies (top down, bottom up and everything in between), the factors influencing their decision-making (looking in and looking out), their evaluation practices (focus on contribution, not attribution) and the importance of capitalizing on windows of opportunity. CONCLUSIONS: This study provides insight into the nature of policy advocacy carried out by professional nursing associations. IMPACT: The findings suggest the need for those leading this important function to think critically about their role in supporting a wide range of audiences, the breadth and depth of their policy priorities and advocacy strategies, the factors that influence their decision-making, and the ways in which their policy advocacy work can be evaluated to move towards greater influence and impact.

Asian Healthcare Workers and Their Experiences of Racism in North America: A Scoping Review.

BACKGROUND: The rising rates of anti-Asian sentiments has recently been called into question by several community activists and scholars. While this collective work has heightened awareness to address anti-Asian racism, the experiences of Asian healthcare workers in particular remains limited. PURPOSE: To map the existing literature on anti-Asian racism experienced by Asian healthcare workers in North American healthcare settings, identify gaps in the current literature base, and inform future areas of anti-Asian racism research. METHODS: A scoping review following Arksey and O'Malley's (2005) methodology with updated guidance by Levac et al. (2010) and Peters et al. (2020) was undertaken. FINDINGS: A total of 3565 articles from database searches were identified from eight databases, with 64 full text articles screened and 15 articles included in this review. Anti-Asian racism amongst healthcare workers has been conceptualized, studied, and understood in three broad categories: levels of racism, descriptions of anti-Asian racism, and the impact of racism. In 60% of the included articles, interpersonal level of racism was solely studied, while 40% articles simultaneously studied interpersonal and institutional levels of racism. Anti-Asian racism was described through three key perspectives: otherness, inferior professional status, and general racial discrimination. Lastly, the impact of Asian healthcare workers' experiences of anti-Asian racism was studied by exploring the impact on mental health and barriers to career advancement. CONCLUSION: Despite the presence of anti-Asian racism, the limited literature examining the complexities of the experiences of anti-Asian racism for Asian healthcare workers is concerning. Future scholarship requires further investigation that comprehensively explores the multiple pathways of anti-Asian racism, the contestation of monolithic stereotypes, and how Asian healthcare workers negotiate both hypervisibility and invisibility within healthcare spaces.

Theory utilization in applied qualitative nursing research.

AIMS: To explore the nuances of theory utilization in qualitative methodologies, discuss the different relationships that applied qualitative methodologies have with theory and use the foundational underpinnings of interpretive description to challenge strongly entrenched ideas of theory that have extended into applied qualitative nursing research. DESIGN: Methodology discussion paper. DATA SOURCES: Narrative literature review and personal observations. CONCLUSION: Many qualitative research traditions have viewed the use of an explicit theoretical framework as an integral grounding for qualitative research studies. Much of the discussion of theory in extant qualitative methodological literature focuses on its use in the context of traditional methodologies such as ethnography, phenomenology and grounded theory, with less attention on methodological approaches developed for applied and practice disciplines such as nursing. Uncritical adoption of ideas about theory based on traditional qualitative methodological conventions can result in findings with little utility for application to the practice context. IMPACT: Nursing researchers should think critically about how theory is used in research endeavours geared towards applied practice and ensure that their methodological choices are in alignment with their philosophical and disciplinary epistemological positionings.

Level of Amyloid-ß (Aß) Binding Leading to Differential Effects on Resting State Functional Connectivity in Major Brain Networks.

INTRODUCTION: Amyloid-ß protein (Aß) is one of the biomarkers for Alzheimer's disease (AD). The recent application of interhemispheric functional connectivity (IFC) in resting-state fMRI has been used as a non-invasive diagnostic tool for early dementia. In this study, we focused on the level of Aß accumulated and its effects on the major functional networks, including default mode network (DMN), central executive network (CEN), salience network (SN), self-referential network (SRN) and sensory motor network (SMN). METHODS: 58 participants (27 Hi Aß (HiAmy) and 31 low Aß (LowAmy)) and 25 healthy controls (HC) were recruited. [18F]flutemetamol PET/CT was performed for diseased groups, and MRI scanning was done for all participants. Voxel-by-voxel correlation analysis was done for both groups in all networks. RESULTS: In HiAmy, IFC was reduced in all networks except SN. A negative correlation in DMN, CEN, SRN and SMN suggests high Aß related to IFC reduction; However, a positive correlation in SN suggests high Aß related to an increase in IFC. In LowAmy, IFC increased in CEN, SMN, SN and SRN. Positive correlation in all major brain networks. CONCLUSION: The level of Aß accumulated demonstrated differential effects on IFC in various brain networks. As the treatment to reduce Aß plaque deposition is available in the market, it may be an option for the HiAmy group to improve their IFC in major brain networks.

The fractional amplitude of low-frequency fluctuations signals related to amyloid uptake in high-risk populations-A pilot fMRI study.

Background: Patients with type 2 diabetes mellitus (T2DM) and subjective cognitive decline (SCD) have a higher risk to develop Alzheimer's Disease (AD). Resting-state-functional magnetic resonance imaging (rs-fMRI) was used to document neurological involvement in the two groups from the aspect of brain dysfunction. Accumulation of amyloid-ß (Aß) starts decades ago before the onset of clinical symptoms and may already have been associated with brain function in high-risk populations. However, this study aims to compare the patterns of fractional amplitude of low-frequency fluctuations (fALFF) maps between cognitively normal high-risk groups (SCD and T2DM) and healthy elderly and evaluate the association between regional amyloid deposition and local fALFF signals in certain cortical regions. Materials and methods: A total of 18 T2DM, 11 SCD, and 18 healthy elderlies were included in this study. The differences in the fALFF maps were compared between HC and high-risk groups. Regional amyloid deposition and local fALFF signals were obtained and further correlated in two high-risk groups. Results: Compared to HC, the altered fALFF signals of regions were shown in SCD such as the left posterior cerebellum, left putamen, and cingulate gyrus. The T2DM group illustrated altered neural activity in the superior temporal gyrus, supplementary motor area, and precentral gyrus. The correlation between fALFF signals and amyloid deposition was negative in the left anterior cingulate cortex for both groups. In the T2DM group, a positive correlation was shown in the right occipital lobe and left mesial temporal lobe. Conclusion: The altered fALFF signals were demonstrated in high-risk groups compared to HC. Very early amyloid deposition in SCD and T2DM groups was observed to affect the neural activity mainly involved in the default mode network (DMN).

Embedding a Global Perspective into Canadian Nursing's Policy Priorities: Observations from the International Council of Nurses' 2021 Congress.

Nursing is a global profession, and the COVID-19 pandemic has illustrated just how interconnected and interdependent nursing and health systems are across jurisdictions. The International Council of Nurses (ICN) is a federation of more than 130 national nursing associations and serves as a key policy voice at the global level. Every two years, their congress brings together thousands of nurses and stakeholders to share and disseminate knowledge. Although Canadian presence has historically been strong in these global fora, there is a lack of literature that focuses on discussing the implications of these global discussions on Canadian nurses' policy and advocacy engagement. In this article, we provide a framework of key policy themes as observed during the ICN's 2021 virtual congress. We discuss how these global policy themes align with Canadian nursing, health and public policy priorities and conclude with questions to guide nurses in embedding a global perspective into their research, policy, education and practice initiatives.

Incremental diagnostic value of 18F-Fluetemetamol PET in differential diagnoses of Alzheimer's Disease-related neurodegenerative diseases from an unselected memory clinic cohort.

To evaluate the incremental diagnostic value of 18F-Flutemetamol PET following MRI measurements on an unselected prospective cohort collected from a memory clinic. A total of 84 participants was included in this study. A stepwise study design was performed including initial analysis (based on clinical assessments), interim analysis (revision of initial analysis post-MRI) and final analysis (revision of interim analysis post-18F-Flutemetamol PET). At each time of evaluation, every participant was categorized into SCD, MCI or dementia syndromal group and further into AD-related, non-AD related or non-specific type etiological subgroup. Post 18F-Flutemetamol PET, the significant changes were seen in the syndromal MCI group (57%, p < 0.001) involving the following etiological subgroups: AD-related MCI (57%, p < 0.01) and non-specific MCI (100%, p < 0.0001); and syndromal dementia group (61%, p < 0.0001) consisting of non-specific dementia subgroup (100%, p < 0.0001). In the binary regression model, amyloid status significantly influenced the diagnostic results of interim analysis (p < 0.01). 18F-Flutemetamol PET can have incremental value following MRI measurements, particularly reflected in the change of diagnosis of individuals with unclear etiology and AD-related-suspected patients due to the role in complementing AD-related pathological information.

Experiences of Older Adults with Frailty Not Completing an Advance Directive: A Qualitative Study of ACP Conversations.

Advance care planning (ACP) facilitates individuals to proactively make decisions on their end-of-life care when they are mentally competent. It is highly relevant to older adults with frailty because they are more vulnerable to cognitive impairment, disabilities, and death. Despite devoting effort to promoting ACP among them, ACP and advance directive completion rates remain low. This study aims to explore the experiences among frail older adults who did not complete an advance directive after an ACP conversation. We conducted a thematic analysis of audiotaped nurse-facilitated ACP conversations with frail older adults and their family members. We purposively selected ACP conversations from 22 frail older adults in the intervention group from a randomized controlled trial in Hong Kong who had ACP conversation with a nurse, but did not complete an advance directive upon completing the intervention. Three themes were identified: "Refraining from discussing end-of-life care", "Remaining in the here and now", and "Relinquishing responsibility over end-of-life care decision-making". Participation in ACP conversations among frail older adults and their family members might improve if current care plans are integrated so as to increase patients' motivation and support are provided to family members in their role as surrogate decision-makers.

COVID-19 vaccine associated axillary lymphadenopathy - A systematic review.

INTRODUCTION: ; COVID-19 vaccines are commonly administered intramuscularly to the arm. Axillary lymphadenopathy has been reported as an adverse event after COVID-19 vaccination. In patients with breast cancers who received COVID-19 vaccination, presence of ipsilateral (or contralateral) lymphadenopathy poses diagnostic dilemma. This systematic review aims to evaluate the incidence and clinical characteristics of vaccine associated axillary lymphadenopathy. METHODS: ; The systematic review was conducted with accordance to the PRISMA statement. The search terms used were "Vaccine" OR "Vaccination" AND "Lymphadenopathy" OR "Lymph node" AND "Covid-19″. RESULTS: ; 31 studies or reports were identified using the predefined keywords from the systematic review protocol. After excluding irrelevant papers (such as guidelines, reviews, opinions and commentaries), 10 studies or reports were included in the review.Pooled incidence of clinically detectable lymphadenopathy after COVID-19 vaccination was 91/22,532 (0.4%). Mean size of the vaccine associated axillary lymphadenopathy was 18.2 mm (Range 16 - 21 mm). Mean duration from vaccination to occurrence of axillary lymphadenopathy was 6.9 days (Range 2 - 18 days). In a study on 119 patients, enlarged axillary lymphadenopathy resolves in 4 to 5 weeks. CONCLUSION: ; Vaccine associated axillary lymphadenopathy is not uncommon. Management of it is based on multidisciplinary decision with patient demographics, vaccination history and radiological finding being taken into account. Additional imaging and biopsy may lead to unnecessary healthcare burden. Proper arrangement of vaccination and imaging regarding timing and laterality should be advocated to avoid confusion and patient anxiety.

Understanding Missing Links in Bipartite Networks With MissBiN.

The analysis of bipartite networks is critical in a variety of application domains, such as exploring entity co-occurrences in intelligence analysis and investigating gene expression in bio-informatics. One important task is missing link prediction, which infers the existence of unseen links based on currently observed ones. In this article, we propose a visual analysis system, MissBiN, to involve analysts in the loop for making sense of link prediction results. MissBiN equips a novel method for link prediction in a bipartite network by leveraging the information of bi-cliques in the network. It also provides an interactive visualization for understanding the algorithm outputs. The design of MissBiN is based on three high-level analysis questions (what, why, and how) regarding missing links, which are distilled from the literature and expert interviews. We conducted quantitative experiments to assess the performance of the proposed link prediction algorithm, and interviewed two experts from different domains to demonstrate the effectiveness of MissBiN as a whole. We also provide a comprehensive usage scenario to illustrate the usefulness of the tool in an application of intelligence analysis.

Prevalence of mild behavioural impairment domains: a meta-analysis.

BACKGROUND: Mild behavioural impairment (MBI) is a neurobehavioural syndrome characterised by later life emergence of persistent neuropsychiatric symptoms. Our previous meta-analysis showed that MBI is prevalent among cognitively normal (CN), subjective cognitive impairment (SCI) and mild cognitive impairment (MCI) subjects. This study is to calculate the pooled prevalence of MBI domains among CN, SCI, and MCI subjects. METHODS: A search of relevant literature published between 1 January 2003 and 6 August 2021 was conducted. Meta-analysis using a random effects model and meta-regression was performed. RESULTS: Ten studies conducted among 12 067 subjects (9758 CN, 1057 SCI and 1252 MCI) with retrievable MBI domains data underwent meta-analysis, revealing pooled prevalence of affective dysregulation (AFD), impulse dyscontrol (IDS), decreased motivation (DMT), social inappropriateness (SIP) and abnormal perception/thought (APT) of 32.84% (95% CI 24.44-42.5%), 26.67% (95% CI 18.24-37.23%), 12.58% (95% CI 6.93-21.75%), 6.05% (95% CI 3.44-10.42%), and 2.81% (95% CI 1.67-4.69%) respectively. AFD and APT domains demonstrated ordinal increase in pooled prevalence from CN, SCI and MCI subgroups, but meta-regression demonstrated no significant difference in MBI domains prevalence among cognitive subgroups (in contrast to the significant increase in MBI prevalence from CN to SCI to MCI). The pooled prevalence of AFD and IDS are greater than that of DMT, SIP and APT among all cognitive subgroups. Several variables were found to explain the high heterogeneity. CONCLUSIONS: AFD and IDS are the two most prevalent MBI domains and remain the same with cognitive deterioration. This finding is potentially relevant to clinical practice.
