Meeting Abstract

The objective of the study is to perform a critical review, exploration, and strong summary of the relationships between personal and ambient concentrations of mainly particulate matter with diameter of 2.5µm or less with the measures of cardiopulmonary health. A comprehensive search was carried out in mainstream bibliographic databases or Medical Subject Headings, including Scien Direct, PubMed, Scopus, and ISI Web of Science. The search was applied to the articles that were published between 2017 and early 2019. Needed article information was extracted from each article by: direct information including journal (research article, review article, meeting abstract, conference abstract, correspondence, author index, editorial board meeting abstract, discussion), book chapter, title, authors, abstract, full text documents of candidate studies, publishing year. Study period, Research (study) method used, types of air pollutants variables studied; Types of organ system disorder or disease studied The conclusions made about the health hazards, impacts on humans or animal models, novel therapeutics, and economic loss. With strict literature search and screening processes, it yielded 140 articles (2017=45; 2018=61; and early 2019=34 articles) from 3,968 articles of initial literature database (1952-early 2019). The main compositions of air pollutants are PM, particularly PM2.5 and PM10, O3, CO, SO2, and NOx. Exposure to O3 is frequently associated with respiratory tract inflammation, whereas exposure to PM, CO, No2, and SO2 is related to pulmonary edema, respiratory and cardiovascular hospitalizations, and cardiopulmonary mortality. Any compromise to endothelial cells, the key components of lung barrier integrity contributes to vascular leakage and inflammation. Endothelial cells could be the target of PM exposure. The various effects on various disease entities contribute to hypothesize that Melatonin might protect the lung integrity against PM2.5-induced acute lung injury. Bufei Huoxue (BFHX) could reduce secretory immunoglobulin A (sIgA) and collagen fibers deposition in lung, thus, improved pulmonary function. In conclusion, identification of various crucial signaling pathway involving PM-induced cardiopulmonary disorders and diseases may assist in the development of effective therapeutics, including clean energy use, clean industrialization, proper agriculture, high land use diversity, and proper urbanization for reduction of the air pollution.

Meeting Abstract

The objective of the study is to perform a critical review, exploration, and strong summary of the roles of mesenchymal stem cell transplantation in treating various diseases, including COVID-19. A comprehensive search was carried out in mainstream bibliographic databases or Medical Subject Headings, including Scien Direct, PubMed, Scopus, ISI Web of Science, and websites of the news. The search was applied to the articles that were published between January 2020 and April 2020. Needed article information was extracted from each article by : 1) direct information including journal (research article, review article, meeting abstract, conference abstract, correspondence, author index, editorial board meeting abstract, discussion), book chapter, title, authors, abstract, full text documents of candidate studies, websites of the news, publishing year; 2) study period; 3) research (study) method used; 4) types of mesenchymal stem cells; and 5) types of human organ system disorder or disease studied. With strict literature search and screening processes, it yielded 6 articles from 76 articles of initial literature databases and websites of the news (January 2020 to April 2020). Anti-inflammatory and immunomodulatory properties of MSCs in the treatment of respiratory diseases were confirmed by at least 17 clinical studies and more than 70 clinical trials are registered in this issue that are available at: https:// www.clinicaltrials.gov. MSC transplantation improves the treatment outcome of COVID-19 patients may be due to controlling inflammatory response and promoting tissue regeneration and repair. In conclusion, Human MSCs are currently being evaluated as a stem cell treatment for a number of diseases, particularly severe COVID-19 and have been demonstrated to be safe in clinical trials. There are some promising reports to apply MSCs therapy to treat COVID-19. MSCs may possibly be one of the most ideal therapeutics, or a combination of treatment to treat patients with COVID-19. Nevertheless, further studies are urgently needed to investigate and optimize a number of variables in the human MSC culture environment by developing a bioprocess that can be operated in accordance with the Good Manufacturing Product (GMP).

The Relationship

BACKGROUND AND OBJECTIVE: Numerous studies have addressed the relationship between paretic knee extension strength and comfortable walking speed after stroke. However, the correlations reported are highly variable. This review sought to summarize the correlational data using meta-analysis. METHODS: Relevant literature was identified via a search of 3 bibliographic databases. Articles were screened and perused for inclusion. Included articles were examined for information on the sample studied, procedures for measuring strength and gait speed, and correlations reported between the 2 variables. Meta-analysis was used to calculate a summary correlation. RESULTS: Of 299 unique articles, 18 met inclusion criteria. Articles were diverse in regard to samples studied, procedures described, and correlations reported. Meta-analysis using data from all included studies revealed a summary correlation of 0.51. For studies using hand-held or isokinetic dynamometry, the summary correlation was 0.46 and 0.59 respectively. CONCLUSIONS: This study provides a better indication of the correlation between paretic knee extension strength and comfortable gait speed than individual studies. The correlation is high enough to provide support for the routine measurement of paretic knee extension force for individuals who have experienced a stroke.

AbstractThis article conducts a contemporary comparative review of the medical literature to update and establish evidence as to which framework among Rotterdam and Marshall computed tomography (CT)-based scoring systems predicts traumatic brain injury (TBI) outcomes better. The scheme followed was following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines for literature search. The search started on August 15, 2020 and ended on December 31, 2020. The combination terms used were Medical Subject Headings terms, combination keywords, and specific words used for describing various pathologies of TBI to identify the most relevant article in each database. PICO question to guide the search strategy was: “what is the use of Marshall (I) versus Rotterdam score (C) in TBI patients (P) for mortality risk stratification (O).” The review is based on 46 references which included a full review of 14 articles for adult TBI patients and 6 articles for pediatric TBI articles comparing Rotterdam and Marshall CT scores. The review includes 8,243 patients, of which 2,365 were pediatric and 5,878 were adult TBI patients. Marshall CT classification is not ordinal, is more descriptive, has better inter-rater reliability, and poor performance in a specific group of TBI patients requiring decompressive craniectomy. Rotterdam CT classification is ordinal, has better discriminatory power, and a better description of the dynamics of intracranial changes. The two scoring systems are complimentary. A combination of clinical parameters, severity, ischemic and hemodynamic parameters, and CT scoring system could predict the prognosis of TBI patients with significant accuracy. None of the classifications has good evidence for use in pediatric patients.

Abstract Background Healthcare and human services increasingly rely on teams of individuals to deliver services. Implementation of evidence-based practices and other innovations in these settings requires teams to work together to change processes and behaviors. Accordingly, team functioning may be a key determinant of implementation outcomes. This systematic review will identify and summarize empirical research examining associations between team functioning and implementation outcomes in healthcare and human service settings. Methods We will conduct a comprehensive search of bibliographic databases (e.g., MEDLINE, PsycINFO, CINAHL, ERIC) for articles published from January 2000 or later. We will include peer-reviewed empirical articles and conference abstracts using quantitative, qualitative, or mixed methods. We will include experimental or observational studies that report on the implementation of an innovation in a healthcare or human service setting and examine associations between team functioning and implementation outcomes. Implementation outcomes of interest are acceptability, adoption, appropriateness, cost, feasibility, fidelity, penetration, and sustainability. Two reviewers will independently screen all titles/abstracts, review full-text articles, and extract data from included articles. We will use the Mixed Methods Appraisal Tool to assess methodological quality/bias and conduct a narrative synthesis without meta-analysis. Discussion Understanding how team functioning influences implementation outcomes will contribute to our understanding of team-level barriers and facilitators of change. The results of this systematic review will inform efforts to implement evidence-based practices in team-based service settings. Systematic review registration PROSPERO CRD42020220168

ObjectivesGout, characterised by hyperuricaemia with monosodium urate crystal formation and inflammation, is the most common inflammatory arthritis in adults. Recent studies have found that elevated uric acid levels are related to the occurrence of dementia. We conducted a study to investigate the association between dementia and gout or hyperuricaemia.DesignSystematic review and meta-analysis of cohort studies.Data sourcesStudies were screened from inception to 28 June 2019 by searching Medline, Embase and the Cochrane Library databases.Eligibility criteriaCohort studies comparing the risk of dementia in patients with gout and hyperuricaemia versus non-gout and non-hyperuricaemia controls were enrolled.Data extraction and analysisTwo reviewers separately selected studies and extracted data using the Medical Subject Headings without restriction on languages or countries. The adjusted HRs were pooled using the DerSimonian and Laird random effects model. Sensitivity analyses were conducted to evaluate the stability of the results. Publication bias was evaluated using Egger’s and Begg’s tests. Quality assessment was performed according to the Newcastle-Ottawa Scale.ResultsFour cohort studies that met the inclusion criteria were included in our meta-analysis. We found that gout and hyperuricaemia did not increase the risk of dementia, with a pooled HR of 0.94 (95% CI 0.69 to 1.28), but might decrease the risk of Alzheimer’s disease (AD), with a pooled HR of 0.78 (95% CI 0.64 to 0.95). There was little evidence of publication bias. Quality assessment of the included studies was high (range: 6–8 points).ConclusionsOur study shows that gout and hyperuricaemia do not increase the risk of dementia. However, gout and hyperuricaemia might have a protective effect against AD. Due to the limited number of research articles, more investigations are needed to demonstrate the potential relationship between dementia and gout or hyperuricaemia.

Despite efforts to promote infant and young child feeding (IYCF) practices, there is no collective review of evidence on IYCF enablers and barriers in India. This review was conducted using 2015 Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines. Six computerized bibliographic databases, Scopus, PubMed, PsycINFO, CINAHL, Embase, and Ovid MEDLINE, were searched for published studies on factors associated with IYCF practices in India from 1 January 1993, to 30 April 2020. IYCF practices examined were early initiation of breastfeeding, exclusive breastfeeding, continued breastfeeding at one year, introduction to solid semi-solid or soft foods, minimum dietary diversity, minimum meal frequency, minimum acceptable diet, continued breastfeeding at two years, predominant breastfeeding, and bottle feeding. In total, 6968 articles were retrieved, and 46 studies met the inclusion criteria. The common enablers of IYCF were higher maternal socioeconomic status (SES) and more frequent antenatal care visits (ANC) (≥3). Common barriers to IYCF practices were low SES and less frequent ANC. The review showed that the factors associated with IYCF practices in India are largely modifiable and multi-factorial. Improving IYCF practices would require the adoption of both facilities- and community-based policy interventions at the subnational and national levels in India.

Adolescent asthma is still a major problem with poor adherence to treatment. Globally, adolescents are devoted users of smartphone technologies and app use in asthma self-management may improve adherence. The objective of this systematic review is to assess the feasibility and efficacy of mobile technology in improving asthma outcomes in adolescents. We conducted an extensive review of the peer-review literature of studies with populations consisting of children and adolescents under 18 years in seven bibliographic databases and Google Scholar. All study designs were considered. Quality assessment of included studies were independently assessed and reported. The search identified 291 articles; of the 16 eligible full-text papers, 8 met the review criteria, reporting two interventional, two qualitative and four observational studies. Samples ranged from 12 to 21 participants. Heterogeneity related to study design and the methods of the included studies prevented meta-analysis. Nevertheless, the intervention studies reported a positive effect of smartphone apps on asthma control, medication adherence and self-efficacy. Smartphone apps may be an effective asthma control tool especially among adolescents who are major users of smartphones; however, conclusions are limited by a lack of controlled trials and adequate sample sizes.
