RESUMEN

Physical activity (PA) in the early years is foundational for growth and development and associated with numerous health benefits. However, the prevalence of PA participation among the pediatric population with disabilities is less clear. This systematic review aimed to synthesize the existing literature on PA levels of young children (0-5.99 years) with disabilities. Empirical quantitative studies were collected from seven databases and reference hand searching; 21 studies were included in the review. PA levels varied widely based on disability type and measurement strategies, but overall, PA levels were low. Future research should address the underrepresentation of measurement and reporting of the PA levels of young children with disabilities.

RESUMEN

PURPOSE: This scoping review summarizes the applications of artificial intelligence (AI) and bioinformatics methodologies in analysis of ocular biofluid markers. The secondary objective was to explore supervised and unsupervised AI techniques and their predictive accuracies. We also evaluate the integration of bioinformatics with AI tools. METHODS: This scoping review was conducted across five electronic databases including EMBASE, Medline, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science from inception to July 14, 2021. Studies pertaining to biofluid marker analysis using AI or bioinformatics were included. RESULTS: A total of 10,262 articles were retrieved from all databases and 177 studies met the inclusion criteria. The most commonly studied ocular diseases were diabetic eye diseases, with 50 papers (28%), while glaucoma was explored in 25 studies (14%), age-related macular degeneration in 20 (11%), dry eye disease in 10 (6%), and uveitis in 9 (5%). Supervised learning was used in 91 papers (51%), unsupervised AI in 83 (46%), and bioinformatics in 85 (48%). Ninety-eight papers (55%) used more than one class of AI (e.g. > 1 of supervised, unsupervised, bioinformatics, or statistical techniques), while 79 (45%) used only one. Supervised learning techniques were often used to predict disease status or prognosis, and demonstrated strong accuracy. Unsupervised AI algorithms were used to bolster the accuracy of other algorithms, identify molecularly distinct subgroups, or cluster cases into distinct subgroups that are useful for prediction of the disease course. Finally, bioinformatic tools were used to translate complex biomarker profiles or findings into interpretable data. CONCLUSION: AI analysis of biofluid markers displayed diagnostic accuracy, provided insight into mechanisms of molecular etiologies, and had the ability to provide individualized targeted therapeutic treatment for patients. Given the progression of AI towards use in both research and the clinic, ophthalmologists should be broadly aware of the commonly used algorithms and their applications. Future research may be aimed at validating algorithms and integrating them in clinical practice.

RESUMEN

Two quinidine-functionalized coumarin molecular probes have been synthesized and have been found to bind metal cations (Cd2+, Co2+, Cu2+, Fe2+, Hg2+, Ni2+, and Zn2+) with high affinity in organic-aqueous media (DMSO-HEPES). The chemodosimeters coordinate with the Zn2+ ions in a two-to-one ratio (molecular probe : Zn2+) with a log ß of 10.0 M-2. Upon the addition of the closed-shell metal ions studied, a fluorescence turn-on via an excimer formation is seen at 542 nm due to the quinaldine moiety adopting a syn arrangement when coordinated to the metal Zn2+ ions. Confocal microscopy monitored free Zn2+ ions in the Human Embryonic Kidney cell line HEK293 by coordinating with the chemodosimter.

RESUMEN

BACKGROUND: During the COVID-19 pandemic, many patient-facing digital self-triage tools were designed and deployed to alleviate the demand for pandemic virus triage in hospitals and physicians' offices by providing a way for people to self-assess their health status and get advice on whether to seek care. These tools, provided via websites, apps, or patient portals, allow people to answer questions, for example, about symptoms and contact history, and receive guidance on appropriate care, which might be self-care. OBJECTIVE: This scoping review aimed to explore the state of literature on digital self-triage tools that direct or advise care for adults during a pandemic and to explore what has been learned about the intended purpose, use, and quality of guidance; tool usability; impact on providers; and ability to forecast health outcomes or care demand. METHODS: A literature search was conducted in July 2021 using MEDLINE, Embase, Scopus, PsycINFO, CINAHL, and Cochrane databases. A total of 1311 titles and abstracts were screened by 2 researchers using Covidence, and of these, 83 (6.76%) articles were reviewed via full-text screening. In total, 22 articles met the inclusion criteria; they allowed adults to self-assess for pandemic virus, and the adults were directed to care. Using Microsoft Excel, we extracted and charted the following data: authors, publication year and country, country the tool was used in, whether the tool was integrated into a health care system, number of users, research question and purpose, direction of care provided, and key findings. RESULTS: All but 2 studies reported on tools developed since early 2020 during the COVID-19 pandemic. Studies reported on tools that were developed in 17 countries. The direction of care advice included directing to an emergency room, seeking urgent care, contacting or seeing a physician, being tested, or staying at home and self-isolating. Only 2 studies evaluated tool usability. No study demonstrated that the tools reduce demand on the health care system, although at least one study suggested that data can predict demand for care and that data allow monitoring public health. CONCLUSIONS: Although self-triage tools developed and used around the world have similarities in directing to care (emergency room, physician, and self-care), they differ in important ways. Some collect data to predict health care demand. Some are intended for use when concerned about health status; others are intended to be used repeatedly by users to monitor public health. The quality of triage may vary. The high use of such tools during the COVID-19 pandemic suggests that research is needed to assess and ensure the quality of advice given by self-triage tools and to assess intended or unintended consequences on public health and health care systems.

RESUMEN

INTRODUCTION: Physical activity in the early years is necessary for setting the foundation for healthy growth and development in later childhood and adolescence. While most published evidence to date focuses on typically developing children, prevalence rates of physical activity among children with disabilities have been less studied. This protocol paper documents the plan of a systematic review, which aims to synthesise the evidence regarding physical activity levels among young children with disabilities. METHODS AND ANALYSIS: Searches are anticipated to commence in May 2022. Empirical quantitative studies will be considered for inclusion if they present intervention or observational data on non-therapeutic (ie, leisure time) physical activity among children <5.99 years with physical, mental, intellectual or sensory impairments. Data sources will be retrieved via electronic database searches (Cumulative Index to Nursing and Allied Health Literature (CINAHL), EBSCO Sports Medicine Database (SPORTDiscus), Medical Literature Analysis and Retrieval System Online (MEDLINE), Elsevier Bibliographic Database (Scopus), Psychological Abstracts (PsycINFO), Education Resources Information Centre (ERIC) and Excerpta Medica Database (EMBASE)). Additional strategies to identify relevant studies will include manual searching and citation tracking of included articles. Titles and abstracts of identified studies will be screened for inclusion, followed by full-text reviews. Three independent reviewers will conduct quality appraisal using the Downs and Black checklist. A summary of included studies will describe the study designs, participant and activity characteristics, and outcomes. ETHICS AND DISSEMINATION: This systematic review involves a secondary analysis of previously published data; therefore, this review does not require ethical approval. The proposed paper will summarise the current evidence base on physical activity levels among young children with a diagnosed disability. The findings from this systematic review will identify gaps to be explored by future research studies and inform future investigations among the paediatric disability population. PROSPERO REGISTRATION NUMBER: CRD42021266585.

RESUMEN

BACKGROUND: The endosomal-lysosomal and autophagy (ELA) pathway may be implicated in the progression of Alzheimer's disease (AD); however, findings thus far have been inconsistent. OBJECTIVE: To systematically summarize differences in endosomal-lysosomal and autophagy proteins in the cerebrospinal fluid (CSF) of people with AD and healthy controls (HC). METHODS: Studies measuring CSF concentrations of relevant proteins in the ELA pathway in AD and healthy controls were included. Standardized mean differences (SMD) with 95% confidence intervals (CI) between AD and healthy controls in CSF concentrations of relevant proteins were meta-analyzed using random-effects models. RESULTS: Of 2,471 unique studies, 43 studies were included in the systematic review and meta-analysis. Differences in ELA protein levels in the CSF between AD and healthy controls were observed, particularly in lysosomal membrane (LAMP-1: NAD/NHC = 348/381, SMD [95% CI] = 0.599 [0.268, 0.930], I2 = 72.8%; LAMP-2: NAD/NHC = 401/510, SMD [95% CI] = 0.480 [0.134, 0.826], I2 = 78.7%) and intra-lysosomal proteins (GM2A: NAD/NHC = 390/420, SMD [95% CI] = 0.496 [0.039, 0.954], I2 = 87.7%; CTSB: NAD/NHC = 485/443, SMD [95% CI] = 0.201 [0.029, 0.374], I2 = 28.5%; CTSZ: NAD/NHC = 535/820, SMD [95% CI] = -0.160 [-0.305, -0.015], I2 = 24.0%) and in proteins involved in endocytosis (AP2B1:NAD/NHC = 171/205, SMD [95% CI] = 0.513 [0.259, 0.768], I2 = 27.4%; FLOT1: NAD/NHC = 41/45, SMD [95% CI] = -0.489 [-0.919, -0.058], I2 <0.01). LC3B, an autophagy marker, also showed a difference (NAD/NHC = 70/59, SMD [95% CI] = 0.648 [0.180, 1.116], I2 = 38.3%)), but overall there was limited evidence suggesting differences in proteins involved in endosomal function and autophagy. CONCLUSION: Dysregulation of proteins in the ELA pathway may play an important role in AD pathogenesis. Some proteins within this pathway may be potential biomarkers for AD.

RESUMEN

INTRODUCTION: This protocol describes the methods for a mixed study systematic review aiming to explore the definitions and measurements of recovery in patients with low back pain, and how perspectives of recovery differ between patients and providers. This review will be the first to review the concept of recovery in patients with low back pain across both quantitative and qualitative literature. METHODS AND ANALYSIS: This protocol has been designed and reported in line with Preferred Reporting Items of Systematic Reviews and Meta-Analyses Protocols. The following databases will be electronically searched from database inception until 30 November 2021: Medline, EMBASE, CINAHL, Cochrane, PEDro. Grey literature will be searched for through targeted searching of ProQuest Dissertations and Theses and handsearching of the references of all included studies. Studies will be included if they include a patient population of >50% with low back pain (with or without leg pain), and mention the concept of recovery within the abstract, methods or results. The Mixed Methods Appraisal Tool will be used for quality assessment of both quantitative and qualitative included studies. Two independent reviewers will conduct the search, screen titles/abstracts and extract relevant data from full texts. Discrepancies between reviewers will be settled by a third reviewer with spinal pain expertise. For syntheses, thematic analysis will be used to analyse both qualitative and quantitative investigations to explore meanings, measurement and perspectives of recovery from a diverse evidence base. There is no clinical trial associated with this protocol. ETHICS AND DISSEMINATION: There are no ethical issues associated with this systematic review, and ethics approval was not required. Once completed, the results of this review will be published in a peer-reviewed journal within the realm of spinal pain to help guide future research inquiries. PROSPERO REGISTRATION NUMBER: CRD42022295804.

RESUMEN

BACKGROUND: Violence towards women with disabilities is most commonly perpetrated by current or former intimate partners and more than half of disabled women experience intimate partner violence in their lifetime. Disabilities differ by presence, type, and complexity, yet are commonly researched collectively. A more nuanced understanding of the relationship between intimate partner violence and episodic disability is required to better support women living with these concurrent challenges. The objective of this scoping review is to investigate and synthesize the literature reporting on intimate partner violence for women living with an episodic disability to identify key concepts and knowledge gaps on this topic. Ultimately, this review aims to improve health services for this stigmatized group of women with episodic disabilities. METHODS: This scoping review will consider all studies that focus on women (18 years of age or older) who have experienced intimate partner violence and have an episodic disability. Episodic disabilities will include multiple sclerosis, chronic fatigue syndrome, fibromyalgia, lupus, or rheumatoid arthritis. The broad review question is what is known about intimate partner violence within the context of women living with an episodic disability? Databases to be searched include MEDLINE (OVID), CINAHL, Embase, PsychInfo, and Scopus with no limits on language or time frame. Joanna Briggs Institute methodology will guide this scoping review to address the review questions outlined in the protocol. For papers that meet the inclusion criteria, data will be extracted, and findings will be presented in tables and narrative form. A PRISMA table will be included to enhance the transparency of the process. A descriptive qualitative approach to analysis will be conducted following Braun and Clarke's reflexive thematic analysis. The findings of the scoping review will be presented through a thematic narrative. DISCUSSION: Findings from this review will be used to identify important priorities for future research based on knowledge gaps and inform both health care practices and health and social interventions for women living with intimate partner violence and episodic disabilities.

RESUMEN

INTRODUCTION: Infectious diseases pose a risk to public health, requiring efficient strategies for disease prevention. Digital health surveillance technologies provide new opportunities to enhance disease prevention, detection, tracking, reporting and analysis. However, in addition to concerns regarding the effectiveness of these technologies in meeting public health goals, there are also concerns regarding the ethics, legality, safety and sustainability of digital surveillance technologies. This scoping review examines the literature on digital surveillance for public health purposes during the COVID-19 pandemic to identify health-related applications of digital surveillance technologies, and to highlight discussions of the implications of these technologies. METHODS AND ANALYSIS: The scoping review will be guided by the framework proposed by Arksey and O'Malley and the guidelines outlined by Colquhoun et al and Levac et al. We will search Medline (Ovid), PsycInfo, PubMed, Scopus, CINAHL (EBSCOhost), ACM Digital Library, Google Scholar and IEEE Explore for relevant studies published between December 2019 and December 2020. The review will also include grey literature. Data will be managed and analysed through an extraction table and thematic analysis. ETHICS AND DISSEMINATION: Findings will be disseminated through traditional academic channels, as well as social media channels and research briefs and infographics. We will target our dissemination to provincial and federal public health organisations, as well as technology companies and community-based organisations managing the public response to the COVID-19 pandemic.

RESUMEN

Multimorbidity, the presence of 1+ chronic condition in an individual, remains one of the greatest challenges to health on a global scale. Although the prevalence of multimorbidity has been well-established, its incidence is not fully understood. This systematic review determined the incidence of multimorbidity across the lifespan; the order in which chronic conditions accumulate to result in multimorbidity; and cataloged methods used to determine and report accumulation of chronic conditions resulting in multimorbidity. Studies were identified by searching MEDLINE, Embase, CINAHL, and Cochrane electronic databases. Two independent reviewers evaluated studies for inclusion and performed quality assessments. Of 36 included studies, there was high heterogeneity in study design and operational definitions of multimorbidity. Studies reporting incidence (n = 32) reported a median incidence rate of 30.7 per 1,000 person-years (IQR 39.5 per 1,000 person-years) and a median cumulative incidence of 2.8% (IQR 28.7%). Incidence was notably higher for persons with older age and 1+ chronic conditions at baseline. Studies reporting patterns in accumulation of chronic conditions (n = 5) reported hypertensive and heart diseases, and diabetes, as among the common starting conditions resulting in later multimorbidity. Methods used to discern patterns were highly heterogenous, ranging from the use of latent growth trajectories to divisive cluster analyses, and presentation using alluvial plots to cluster trajectories. Studies reporting the incidence of multimorbidity and patterns in accumulation of chronic conditions vary greatly in study designs and definitions used. To allow for more accurate estimations and comparison, studies must be transparent and consistent in operational definitions of multimorbidity applied.

RESUMEN

Although research to date has shown that there can be no health or sustainable development without good mental health, mental illness continues to significantly impact societies. A major challenge confronting people with mental illnesses and their families is the stigma that they endure. In this study, empirical literature was reviewed to assess policies and interventions that seek to reduce familial mental illness stigma across four countries. We used Arksey and O'Malley methodological framework, and a qualitative content analysis was employed to augment the descriptive data extracted. Seven studies published between 2000 and 2020 were analyzed. We propose herein three themes that align with interventions to reduce familial mental illness stigma: transformative education, sharing and disclosure, and social networking and support. The findings indicate that persuasive and purposeful education directed at the public to correct misconceptions surrounding mental illness, with attention to language, may help in reducing familial mental illness stigma. Disclosure of mental illness is encouraged among persons with mental illnesses and their families as a strategy to enhance mutual understanding. Social sharing also affords persons with mental illnesses opportunities to engage with their peers at different levels within the public sphere. Apart from these recommendations, we have noted a paucity of broad governmental-level policies and interventions to comprehensively address the negative attitudes of families toward their relatives. Future work must address this gap to identify effective interventions to create healthier and supportive environments that address familial mental illness stigma.

RESUMEN

PURPOSE: Global access to adequate resources to address postpartum depression (PPD) are limited and, at times, not reflective of the needs of pregnant women and new mothers. Gathering information about the preferences and needs of women when designing and implementing Internet-based programs is warranted, especially given the diversity of experiences related to childbirth. Thus, the aim of this study was to obtain user feedback on the content, structural, and cultural factors associated with a fully automated online PPD prevention intervention that, like similar programs, suffered from poor adherence and engagement. METHODS: Following the completion of the Mothers and Babies Internet Course (eMB), an online prevention of PPD trial, a convenience sampling method was used to invite consenting participants to return to the site. Participants provided anonymous feedback on how to improve and adapt the eMB based on screenshots and video content from the Internet intervention. Demographic information and engagement in the online trial were examined as factors influencing participant responses. RESULTS: One hundred nineteen English and Spanish speaking women from 27 countries and territories provided feedback about the eMB. Content-based feedback included requesting additional detail in explanations and simplifying recommended exercises. Structure-based feedback included requests for more visual representations of the materials. In general, participants did not explicitly suggest culturally specific feedback that differed by geographic region, but instead reported similar themes related to motherhood and childrearing. An unexpected finding that only emerged among English-speaking participants was the need for the eMB to address perfectionism and introspection as factors that impact motherhood. Relative to those who did not access the eMB in the parent study, women who did thought the intervention content was acceptable (i.e., no suggested changes) and provided feedback that referenced maternal stress and pregnancy experiences. Age, education, pregnancy status and number of children were not significant factors associated with participants' use of the eMB. CONCLUSIONS: Findings from this study offer preliminary information about the needs and preferences of an international sample of childrearing women who access automated Internet interventions to manage mood changes during the perinatal period.

RESUMEN

BACKGROUND: Depression that occurs during the perinatal period has substantial costs for both the mother and her baby. Since in-person care often falls short of meeting the global need of perinatal women, Internet interventions may function as an alternate to help women who currently lack adequate access to face-to-face psychological resources. However, at present there are insufficient empirically supported Internet-based resources for perinatal women. OBJECTIVE: The aim of this study is to compare the relative efficacy of Internet-based cognitive behavioral therapy (CBT) to a novel Internet-based compassionate mind training approach (CMT) across measures of affect, self-reassurance, self-criticizing, self-attacking, self-compassion, depression, and anxiety. While CBT has been tested and has some support as an Internet tool for perinatal women, this is the first trial to look at CMT for perinatal women over the Internet. METHODS: Participants were recruited through Amazon Mechanical Turk (MTurk) and professional networks. Following completion of demographic items, participants were randomly assigned to either the CBT or CMT condition. Each condition consisted of 45-minute interactive didactic and follow-up exercises to be completed over the course of two weeks. RESULTS: Post course data was gathered at two weeks. A 2x2 repeated measures analysis of variance will be conducted to analyze differences between conditions at post course. CONCLUSIONS: The implications of the trial will be discussed as well as the strengths and limitations of MTurk as a tool for recruitment. We will also briefly introduce the future directions along this same line of research.
