Methods for conducting a living evidence profile on mpox: An evidence map of the literature

AbstractBackgroundIn May of 2022, several cases of mpox were identified in multiple nonendemic countries and on July 23, 2022 the World Health Organization declared mpox a Public Health Emergency of International Concern. During the first six months of the outbreak there was an urgent need to have up‐to‐date synthesized evidence on mpox to inform public health decision‐making. At this point, evidence is changing too quickly for traditional evidence synthesis methods, as systematic reviews were out‐of‐date before publication. This paper describes the framework developed to manage and maintain a living evidence profile (LEP) to systematically identify, classify and synthesize evidence on a broad range of mpox topics at a rapid pace as the outbreak unfolded.MethodsThe LEP framework was based on principles of evidence synthesis, risk assessment, priority epidemiological parameters for infectious disease modeling and consultation with experts. The framework consisted of a systematic search conducted twice weekly; study selection; categorization into pre‐determined foci and data extraction; integration and synthesis of evidence; internal peer‐review and dissemination to stakeholders.ResultsBetween April 14 and December 15, 2022, 2287 citations were identified, 687 were primary research studies or surveillance reports on the 2022 mpox outbreak and 496 were included in the final LEP. Each study was mapped to one of 32 foci and evidence was narratively synthesized. From June to December 2022, 23 LEPs were produced (approximately weekly) along with a searchable database of extracted data of the mpox literature. They were disseminated globally to public health researchers and decision‐makers to inform public health response efforts.ConclusionsThe LEP framework is applicable to other public health emergencies when a rapid synthesis cycle is required because the evidence is evolving quickly. This efficient methodology for creating up‐to‐date summaries of the current evidence during the first few months of an outbreak or emergency supports public health decision‐making and response activities.

Top 100 most-cited articles on tau protein: a bibliometric analysis and evidence mapping.

Tau, a microtubule-associated protein extensively distributed within the central nervous system (CNS), exhibits close associations with various neurodegenerative disorders. Here, we aimed to conduct a qualitative and quantitative bibliometric study of the top 100 most-cited publications on tau protein and reveal the current research hotspots and future perspectives. The relevant literature was retrieved from the Web of Science Core Collection. CiteSpace (v6.2.R4) and VOSviewer (1.6.19) were adopted for bibliometric analysis with statistical and visual analysis. Citations per article ranged from 615 to 3,123, with a median number of 765.5 times. "Neuroscience" emerged as the most extensively researched subject in this field. The USA has emerged as the leading country, with a publication record (n = 65), total citations (n = 66,543), strong centrality (0.29), and extensive international collaborations. Harvard University (n = 11) and the University of California, San Francisco (n = 11) were the top two institutions in terms of publications. Neuron dominated with 13 articles in the 37 high-quality journals. M. Goedert from the MRC Laboratory of Molecular Biology was the most productive (n = 9) and top co-cited (n = 179) author. The most frequently studied keywords were Alzheimer's disease (n = 38). Future research is anticipated to intensify its focus on the pathogenesis of various tau-related diseases, emphasizing the phosphorylation and structural alterations of tau protein, particularly in Alzheimer's disease. The pathogenesis of various tau-related diseases, including the phosphorylation and structural alterations of the tau protein, will be the primary focus of future research, with particular emphasis on Alzheimer's disease as a central area of investigation.

Effectiveness and Cost-Effectiveness of Self-Management Interventions for Adults Living with Heart Failure to Improve Patient-Important Outcomes: An Evidence Map of Randomized Controlled Trials

Self-management interventions (SMIs) may enhance heart failure (HF) outcomes and address challenges associated with disease management. This study aims to review randomized evidence and identify knowledge gaps in SMIs for adult HF patients. Within the COMPAR-EU project, from 2010 to 2018, we conducted searches in the databases MEDLINE, CINAHL, Embase, Cochrane, and PsycINFO. We performed a descriptive analysis using predefined categories and developed an evidence map of randomized controlled trials (RCTs). We found 282 RCTs examining SMIs for HF patients, comparing two to four interventions, primarily targeting individual patients (97%) globally (34 countries, only 31% from an European country). These interventions involved support techniques such as information sharing (95%) and self-monitoring (62%), often through a mix of in-person and remote sessions (43%). Commonly assessed outcomes included quality of life, hospital admissions, mortality, exercise capacity, and self-efficacy. Few studies have focused on lower socio-economic or minority groups. Nurses (68%) and physicians (30%) were the primary providers, and most studies were at low risk of bias in generating a random sequence for participant allocation; however, the reporting was noticeably unclear of methods used to conceal the allocation process. Our analysis has revealed prevalent support techniques and delivery methods while highlighting methodological challenges. These findings provide valuable insights for researchers, clinicians, and policymakers striving to optimize SMIs for individuals living with HF.

Nature-Based Interventions Targeting Elderly People's Health and Well-Being: An Evidence Map.

Healthy aging encompasses more than the absence of disease, emphasizing the preservation of functional abilities for enhanced well-being and quality of life. Nature-based interventions are scientifically proven contributors to healthy aging. To develop an evidence map showcasing nature-based interventions targeting older individuals' health and well-being. The evidence map was developed through critical analysis of systematic reviews and clinical trials utilizing the tools AMSTAR2 and CONSORT. A systematic search spanning the past decade was conducted across databases: Cochrane, SCOPUS, PubMed, Web of Science, Embase, and LILACS. Twelve articles met the eligibility criteria. Nature-based interventions such as forest bathing, hiking, therapeutic gardens, virtual reality, and forest sounds were identified. Outcomes were categorized into physical aspects (cardiovascular and pulmonary; neuro-immuno-endocrinological) and mental/behavioral aspects. The final map integrated interventions, outcomes, and quality assessments. The survey highlights the positive impact of nature-based interventions on the health of the elderly. This study provides insights across various domains, fostering the development of programs and policies in management to promote healthy aging. Regarding healthcare, it encourages discourse among professionals regarding the integration of nature-based practices for equitable care in both individual and group settings. Furthermore, it underscores the need for research in the Southern Hemisphere, particularly in Brazil, where the study was conducted.

The indirect effects of CMV reactivation on patients following allogeneic hematopoietic stem cell transplantation: an evidence mapping

Cytomegalovirus (CMV) reactivation following allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains a challenging problem, and the impact on the risk of overall mortality (OM) and non-relapse mortality (NRM) in patients following allo-HSCT is still controversial. Utilizing the evidence mapping method, we aimed to assess the effect of CMV infection on outcomes of patients post-transplantation and identify research gaps through systematic reviews (SRs) and clinical studies. PubMed, EMBASE, Web of Science, and Cochrane library databases were searched from inception until 5 July 2022 to identify relevant literature. After systematic literature screening and data extraction, evidence mapping of the effects of CMV reactivation on patients post-allo-HSCT was conducted. Three SRs and 22 clinical studies were included. In one SR, CMV reactivation was associated with an increased risk of mortality (HR 1.46; 95% CI, 1.24–1.72; P ≤ 0.001). In two SRs, CMV reactivation was associated with NRM. One SR reported CMV reactivation was potentially associated with significant protection against relapse in patients with acute myelocytic leukemia (AML), but no significant correlation with graft-versus-host disease (GVHD) was found. Lastly, in one SR CMV reactivation significantly increased the risk of invasive fungal disease (IFD). Most clinical articles reported that CMV reactivation increased the risk of renal dysfunction, poor graft function, re-hospitalization, and bacterial infections. CMV reactivation following allo-HSCT is associated with an increased risk of OM, NRM, IFD, and renal dysfunction, as well as a reduced risk of relapse in patients with AML.

Is musculoskeletal pain associated with increased muscle stiffness? Evidence map and critical appraisal of muscle measurements using shear wave elastography.

Approximately 21% of the world's population suffers from musculoskeletal conditions, often associated with sensations of stiff muscles. Targeted therapy requires knowing whether typically involved muscles are objectively stiffer compared to asymptomatic individuals. Muscle stiffness is quantified using ultrasound shear wave elastography (SWE). Publications on SWE-based comparisons of muscle stiffness between individuals with and without musculoskeletal pain are increasing rapidly. This work reviewed and mapped the existing evidence regarding objectively measured muscle stiffness in musculoskeletal pain conditionsand surveyed current methods of applying SWE to measure muscle stiffness. A systematic search was conducted in PubMed and CINAHL using the keywords "muscle stiffness","shear wave elastography","pain","asymptomatic controls" and synonyms. The search was supplemented by a hand search using Google Scholar. Included articles were critically appraised with the AXIS tool, supplemented by items related to SWE methods. Results were visually mapped and narratively described. Thirty of 137 identified articles were included. High-quality evidence was missing. The results comprise studies reporting lower stiffness in symptomatic participants, no differences between groupsand higher stiffness in symptomatic individuals. Results differed between pain conditions and muscles, and also between studies that examined the same muscle(s) and pathology. The methods of the application of SWE were inconsistent and the reporting was often incomplete. Existing evidence regarding the objective stiffness of muscles in musculoskeletal pain conditions is conflicting. Methodological differences may explain most of the inconsistencies between findings. Methodological standards for SWE measurements of muscles are urgently required.

Illuminating the landscape of sibling relationship quality: An evidence and gap map.

This paper used an evidence and gap map (EGM) to advance the scientific understanding of sibling relationship quality among children aged 2 to 18 years by synthesizing literature on 277 empirical studies from 1985 to 2022 to delineate patterns of study design, sampling, and measurement. Most existing research has utilized majority of White, middle-to-upper class, and/or two-caregiver family samples. Nearly 85% (n = 235) of studies used quantitative methods to measure sibling relationship quality across eight domains: conflict, warmth/affection, quality, cohesion, hostility, power/control, positive engagement, and conflict management. A total of 122 studies used a measure of sibling relationship quality as a predictor of sibling behavior, social, psychological, cognitive, health, or physiological outcomes. Future directions for research are discussed.

Streamlining search methods to update evidence and gap maps: A case study using intergenerational interventions.

Evidence and Gap Maps (EGMs) should be regularly updated. Running update searches to find new studies for EGMs can be a time-consuming process. Search Summary Tables (SSTs) can help streamline searches by identifying which resources were most lucrative for identifying relevant articles, and which were redundant. The aim of this study was to use an SST to streamline search methods for an EGM of studies about intergenerational activities. To produce the EGM, 15 databases were searched. 8638 records were screened and 500 studies were included in the final EGM. Using an SST, we determined which databases and search methods were the most efficient in terms of sensitivity and specificity for finding the included studies. We also investigated whether any database performed particularly well for returning particular study types. For the best performing databases we analysed the search terms used to streamline the strategies. No single database returned all of the studies included in the EGM. Out of 500 studies PsycINFO returned 40% (n = 202), CINAHL 39% (n = 194), Ageline 25% (n = 174), MEDLINE 23% (n = 117), ERIC 20% (n = 100) and Embase 19% (n = 98). HMIC database and Conference Proceedings Citation Index-Sciencevia Web of Science returned no studies that were included in the EGM. ProQuest Dissertations & Theses (PQDT) returned the highest number of unique studies (n = 42), followed by ERIC (n = 33) and Ageline (n = 29). Ageline returned the mostrandomised controlled trials(42%) followed by CINAHL (34%), MEDLINE (29%) and CENTRAL (29%). CINAHL, Ageline, MEDLINE and PsycINFO performed the best for locating systematic reviews. (62%, 46% and 42%respectively). CINAHL, PsycINFO and Ageline performed best for qualitative studies (41%, 40% and 34%). The Journal of Intergenerational Relationships returned more included studies than any other journal (16%). No combinations of search terms were found to be better in terms of balancing specificity and sensitivity than the original search strategies. However, strategies could be reduced considerably in terms of length without losing key, unique studies. Using SSTs we have developed a method for streamlining update searches for an EGM about intergenerational activities. For future updates we recommend that MEDLINE, PsycINFO, ERIC, Ageline, CINAHL and PQDT are searched. These searches should be supplemented by hand-searching the Journal of Intergenerational Relationships and carrying out backwards citation chasing on new systematic reviews. Using SSTs to analyse database efficiency could be a useful method to help streamline search updates for other EGMs.

An Evidence Map of Clinical Practice Guideline Recommendations on Stroke Rehabilitation.

The purpose of this study was to provide an evidence map for explaining research trends and gaps. Four databases and CPGs-related websites were searched up to March 2022. Basic information, methodological quality, reporting quality of CPGs, and similar stroke recommendations were extracted. The methodological and reporting quality of stroke CPGs were evaluated using the AGREE II instrument and the RIGHT checklist. The bubble plot format of the evidence map helped visualize the overall quality. Data management and analysis were performed using Excel 2013 and SPSS 22.0 software. A total of 12 CPGs, published between 1997 and 2020 were included for in-depth analysis. The identified CPGs had a mixed quality and scored poorly in the developmental rigor and applicability domains by AGREE II. According to the RIGHT checklist, field four (clarity of expression) showed the highest (79.2%), and field three (rigor of formulation) secured the lowest (28%) reporting rates. The stroke rehabilitation recommendations primarily focused on organizational management, timing and intensity, rehabilitation and nutritional management of dysphagia, return to work, communication, speech, and language function. This would promote improvement in developing trustworthy CPGs for stroke rehabilitation.

Effectiveness of road safety interventions: An evidence and gap map.

Road Traffic injuries (RTI) are among the top ten leading causes of death in the world resulting in 1.35 million deaths every year, about 93% of which occur in low- and middle-income countries (LMICs). Despite several global resolutions to reduce traffic injuries, they have continued to grow in many countries. Many high-income countries have successfully reduced RTI by using a public health approach and implementing evidence-based interventions. As many LMICs develop their highway infrastructure, adopting a similar scientific approach towards road safety is crucial. The evidence also needs to be evaluated to assess external validity because measures that have worked in high-income countries may not translate equally well to other contexts. An evidence gap map for RTI is the first step towards understanding what evidence is available, from where, and the key gaps in knowledge. The objective of this evidence gap map (EGM) is to identify existing evidence from all effectiveness studies and systematic reviews related to road safety interventions. In addition, the EGM identifies gaps in evidence where new primary studies and systematic reviews could add value. This will help direct future research and discussions based on systematic evidence towards the approaches and interventions which are most effective in the road safety sector. This could enable the generation of evidence for informing policy at global, regional or national levels. The EGM includes systematic reviews and impact evaluations assessing the effect of interventions for RTI reported in academic databases, organization websites, and grey literature sources. The studies were searched up to December 2019. The interventions were divided into five broad categories: (a) human factors (e.g., enforcement or road user education), (b) road design, infrastructure and traffic control, (c) legal and institutional framework, (d) post-crash pre-hospital care, and (e) vehicle factors (except car design for occupant protection) and protective devices. Included studies reported two primary outcomes: fatal crashes and non-fatal injury crashes; and four intermediate outcomes: change in use of seat belts, change in use of helmets, change in speed, and change in alcohol/drug use. Studies were excluded if they did not report injury or fatality as one of the outcomes. The EGM is presented in the form of a matrix with two primary dimensions: interventions (rows) and outcomes (columns). Additional dimensions are country income groups, region, quality level for systematic reviews, type of study design used (e.g., case-control), type of road user studied (e.g., pedestrian, cyclists), age groups, and road type. The EGM is available online where the matrix of interventions and outcomes can be filtered by one or more dimensions. The webpage includes a bibliography of the selected studies and titles and abstracts available for preview. Quality appraisal for systematic reviews was conducted using a critical appraisal tool for systematic reviews, AMSTAR 2. The EGM identified 1859 studies of which 322 were systematic reviews, 7 were protocol studies and 1530 were impact evaluations. Some studies included more than one intervention, outcome, study method, or study region. The studies were distributed among intervention categories as: human factors (n = 771), road design, infrastructure and traffic control (n = 661), legal and institutional framework (n = 424), post-crash pre-hospital care (n = 118) and vehicle factors and protective devices (n = 111). Fatal crashes as outcomes were reported in 1414 records and non-fatal injury crashes in 1252 records. Among the four intermediate outcomes, speed was most commonly reported (n = 298) followed by alcohol (n = 206), use of seatbelts (n = 167), and use of helmets (n = 66). Ninety-six percent of the studies were reported from high-income countries (HIC), 4.5% from upper-middle-income countries, and only 1.4% from lower-middle and low-income countries. There were 25 systematic reviews of high quality, 4 of moderate quality, and 293 of low quality. The EGM shows that the distribution of available road safety evidence is skewed across the world. A vast majority of the literature is from HICs. In contrast, only a small fraction of the literature reports on the many LMICs that are fast expanding their road infrastructure, experiencing rapid changes in traffic patterns, and witnessing growth in road injuries. This bias in literature explains why many interventions that are of high importance in the context of LMICs remain poorly studied. Besides, many interventions that have been tested only in HICs may not work equally effectively in LMICs. Another important finding was that a large majority of systematic reviews are of low quality. The scarcity of evidence on many important interventions and lack of good quality evidence-synthesis have significant implications for future road safety research and practice in LMICs. The EGM presented here will help identify priority areas for researchers, while directing practitioners and policy makers towards proven interventions.

Strategies for enhancing the representation of women in clinical trials: an evidence map

BackgroundEquitable sex- and gender-based representation in clinical trials is an essential step to ensuring evidence-based care for women. While multi-institutional actions have led to significant improvements in the inclusion of women in trials, inequity persists in areas like sex-neutral cancers and cardiovascular disease. We sought to identify strategies described or evaluated to boost the inclusion of women in clinical trials.MethodsWe used evidence mapping methodology to examine the breadth of relevant literature. We developed an a priori protocol and followed reporting guidance from the Preferred Reporting Items for Systematic Reviews and Meta-Analysis where applicable. We searched MEDLINE® (via PubMed) and EMBASE (via Elsevier) databases from inception through April 4, 2023, and used standardized procedures incorporating duplication and data verification. We included articles that described strategies to improve the recruitment and retention of women in clinical trials.ResultsWe identified 122 articles describing recruitment and retention strategies for 136 trials (377,595 women). Only one article distinguished between the sex and gender identity of participants, and none defined their use of the terms such as “women” or “female”. The majority of articles (95%) described recruitment for only women, and 64% were conducted in the USA. Ninety-two articles (75%) described strategies in the context of sex-specific conditions (e.g., gynecologic diagnosis). The majority of included articles evaluated a behavioral intervention (52%), with 23% evaluating pharmacologic interventions and 4% invasive interventions. The most common trial phase for reported strategies was during outreach to potential participants (116 articles), followed by intervention delivery (76), enrollment (40), outcomes assessment (21), analysis and interpretation (3), and dissemination (4). We describe specific types of strategies within each of these phases.ConclusionsMost of the existing literature describing strategies to improve the inclusion of women draws from trials for sex-specific conditions and is largely related to outreach to potential participants. There is little information about how and if studies have attempted to proportionally increase the inclusion of women in trials with both men and women or those focused on invasive and pharmacologic interventions. Future work in this area should focus on how to increase the participation of women in mixed-sex studies and on those areas with remaining inequities in trial participation.

SyROCCo: enhancing systematic reviews using machine learning

Abstract The sheer number of research outputs published every year makes systematic reviewing increasingly time- and resource-intensive. This paper explores the use of machine learning techniques to help navigate the systematic review process. Machine learning has previously been used to reliably “screen” articles for review – that is, identify relevant articles based on reviewers’ inclusion criteria. The application of machine learning techniques to subsequent stages of a review, however, such as data extraction and evidence mapping, is in its infancy. We, therefore, set out to develop a series of tools that would assist in the profiling and analysis of 1952 publications on the theme of “outcomes-based contracting.” Tools were developed for the following tasks: assigning publications into “policy area” categories; identifying and extracting key information for evidence mapping, such as organizations, laws, and geographical information; connecting the evidence base to an existing dataset on the same topic; and identifying subgroups of articles that may share thematic content. An interactive tool using these techniques and a public dataset with their outputs have been released. Our results demonstrate the utility of machine learning techniques to enhance evidence accessibility and analysis within the systematic review processes. These efforts show promise in potentially yielding substantial efficiencies for future systematic reviewing and for broadening their analytical scope. Beyond this, our work suggests that there may be implications for the ease with which policymakers and practitioners can access evidence. While machine learning techniques seem poised to play a significant role in bridging the gap between research and policy by offering innovative ways of gathering, accessing, and analyzing data from systematic reviews, we also highlight their current limitations and the need to exercise caution in their application, particularly given the potential for errors and biases.

Evidence map of chikungunya treatmentsMapa de la evidencia sobre el tratamiento del chikunguña

Based on a review of the literature, to create a map of the available evidence on the treatment methods for chikungunya. In May 2022, a literature search on chikungunya was conducted using the PubMed and Virtual Health Library platforms. To create the evidence map, studies that mentioned chikungunya fever were selected and characterized based on the type of intervention, outcome, and direction of the effect (positive, negative, potentially positive or potentially negative, inconclusive, or no effect), following the methodology recommended by the Latin American and Caribbean Center on Health Sciences Information (BIREME). Fifteen studies (systematic reviews, controlled clinical trials, and narrative reviews) with both pharmacological and non-pharmacological interventions were included. All interventions focused on symptom mitigation; no study specifically investigated ways to combat the virus itself. Only one study on pharmacological interventions reported a positive effect, involving monotherapy with hydroxychloroquine and combined therapy with methotrexate plus sulfasalazine and hydroxychloroquine for reducing and relieving pain caused by post-chikungunya arthritis. The only study to report a negative effect described the use of chloroquine for post-chikungunya arthralgia. Among non-pharmacological interventions, positive effects were noted for transcranial direct current stimulation, elastic band exercises, and the Pilates method, particularly for pain relief and improvement of joint function. Although the review did not identify any treatments that act directly on the virus after the onset of the disease, the evidence map suggests that it is possible to treat the symptoms and sequelae of chikungunya with both pharmacological and non-pharmacological therapies.

Psychological and physiological health outcomes of virtual reality-based mindfulness interventions: A systematic review and evidence mapping of empirical studies.

In the past two decades, mindfulness, rooted in Buddhist traditions, has gained considerable scientific interest. Virtual reality (VR) technology, in particular head-mounted displays, offers immersive experiences and is examined in this systematic review in terms of VR-based mindfulness interventions and their effects on psychological and physiological health outcomes. Using the Preferred Reporting Items for Systematic Review and Meta Analyses guidelines, a systematic search was conducted with the following search terms: [(mindful* OR "meditat*") AND ("virtual reality" OR "VR") AND (health OR physio* OR psycho* OR mental OR physical)]. Considering critiques of methodological quality in existing systematic reviews, this study adopts Boell and Cecez-Kecmanovic's hermeneutic approach, critically evaluating research outcomes. Psychological benefits include improved anxiety, mindfulness, emotions, disease patterns, affect, stress, (presleep) arousal, meditation and others. Physiological effects focus on neurobiological markers, heart rate/heart rate variability, pain, blood pressure, cortisol and galvanic skin resistance. Evidence mapping shows that more research has been conducted in the last 6 years, particularly by North American and South Korean authors, and points to gaps in study methodology. In addition, attention regulation is identified as a primary mindfulness mechanism in VR scenarios, often in nature-based virtual environments, with mainly single-session studies lasting 5 or 10 minutes. Critical mapping reveals the need for additional studies to support and extend initial findings in this emerging research field. Methodologically, there is a call for more true-experimental studies to enhance rigor. From a content perspective, VR protocols are currently still strongly characterized by single-session interventions, which makes it especially difficult to make a dose-response statement regarding long-term effects. In summary, the studies provide important initial findings on psychological and physiological effects of VR-based mindfulness interventions on health. In addition, the need for more methodologically rigorous studies was emphasized, along with other methodological adjustments that must be carefully considered in the planning of future studies.

Profiling research on PFAS in wildlife: Systematic evidence map and bibliometric analysis

Abstract Per‐ and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals that have been in use for over 70 years. Their ubiquitous distribution and harmful effects pose a threat to wildlife worldwide. To provide a comprehensive synopsis and show the gaps and gluts of existing research on PFAS exposure in wildlife, we created a systematic map and bibliographic analysis of the literature. We followed our protocol to conduct a systematic literature search on Scopus, Web of Science and five other databases. In two steps (title/abstract/keywords and full‐text), we screened peer‐reviewed empirical articles, preprints and theses in English that studied the concentration of at least one of 34 PFAS compounds in free‐ranging wildlife or their parts/products. Following the protocol, we extracted data and performed a critical appraisal. We included 581 publications. From the first and only paper in 2001, there was a linear annual increase to 54 papers in 2021. While PFOS (97% of studies), PFOA (91%) and long‐chain PFAS in general were the most measured, few studies investigated new‐generation PFAS (e.g. GenX and ADONA). Across the studied 1042 species from 26 taxonomic classes, the most frequent were the common carp (Cyprinus carpio, 8%), polar bear (Ursus maritimus, 6%) and European perch (Perca fluviatilis, 5%). Most sampling took place in the United States (17%), Norway (13%), Canada (12%) and China (10%), which were also the main publishing countries. Polar regions attracted significant research interest from countries all around the globe. Aquatic habitats (marine: 31%, freshwater: 28%) of temperate zones were the most common locations for sample collection. We encourage researchers to work towards closing the following gaps: investigating new‐generation PFAS, assessing PFAS in mid‐ and low‐income countries and performing more long‐term studies, especially on invertebrates. We note the recent rise in studies on the physiological consequences of PFAS exposure and encourage further work on this crucial topic. Furthermore, we recommend that the statement of potential and actual conflicts of interest, and the provision of raw data and analysis code should be made compulsory by all journals and routinely enforced. This practice will mitigate conflict of interest and ensure reproducibility.

Funcionalidade da linguagem no transtorno do espectro do autismo: uma revisão de escopo

ABSTRACT Purpose: to map and synthesize scientific evidence on language functioning in children and adolescents with autism spectrum disorder Autism Spectrum Disorder. Methods: this scoping review aimed at mapping and synthesizing scientific evidence on language functioning in children and adolescents with Autism Spectrum Disorder. A research question, article selection, and compilation of results were used as research strategies. The selection criteria were studies with samples of children and adolescents, addressing Autism Spectrum Disorder, speech-language-hearing therapy, communication, language, and functioning. After independent evaluators read the titles, keywords, abstracts, and full texts, they recorded the following data for the review: year of publication, type of study, country of origin, sample size, age of participants, instruments used, language subsystems assessed, and results. Literature review: the search found 1,056 articles, of which 536 were read in full, and 16 were included. There was great variability in assessment instruments and few studies involving adolescents. Individuals with Autism Spectrum Disorder had changes in language functioning related to pragmatics, morphosyntax, semantics, and phonology. Conclusion: the preliminary evidence map indicates that children and adolescents with ASD have a variety of language changes.

Evidence mapping of clinical practice guidelines on nutritional management for pressure injuries and their quality.

The safety and efficacy of nutritional management for pressure injuries (PIs) have been the subjects of ongoing interest. Some evidence demonstrated that nutrition is essential for skin and tissue viability, supporting tissue repair for healing the pressure injury. This investigation aimed to systematically review clinical practice guidelines (CPGs) for the nutritional management of PIs and furnish an evidence map to assess research trends and CPG gaps. The PubMed, Embase, and guidelines databases, and society websites were searched for CPGs for the nutritional management of PIs. The basic recommendations for the nutritional management of PIs, method quality, and reporting CPGs quality were identified and imported into Excel. Four researchers independently elucidated each CPG's quality via the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument and the Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist. All bubble charts were generated using Excel software. This review included 12 CPGs with a combined 23 recommendations. The nutrition screening and assessment were summarized on the basis of the PI recommendations for 6 major items, 12 items on nutrition management, and 3 on PI education. The assessed CPGs had mixed quality, and the highest score ± standard deviation based on the clarity of presentation was 83.46 ± 7.62, whereas the lowest mean score based on AGREE II applicability was 53.31 ± 16.90. Field 1 (basic information) in the RIGHT checklist had the greatest reporting rate (68.06%), whereas field 5 (review and quality assurance) had the lowest CPGs quality (41.67%). This investigation furnishes an evidence map and provides new perspectives on the CPGs for the nutritional management of PIs. However, the CPGs included still need improvement, especially in the applicability and editorial independence domains.

Evidence mapping on how to perform an optimal surgical repair of large hiatal hernias

BackgroundSymptomatic and large hiatal hernia (HH) is a common disorder requiring surgical management. However, there is a lack of systematic, evidence-based recommendations summarizing recent reviews on surgical treatment of symptomatic HH. Therefore, this systematic review aimed to create evidence mapping on the key technical issues of HH repair based on the highest available evidence.MethodsA systematic review identified studies on eight key issues of large symptomatic HH repair. The literature was screened for the highest level of evidence (LE from level 1 to 5) according to the Oxford Center for evidence-based medicine’s scale. For each topic, only studies of the highest available level of evidence were considered.ResultsOut of the 28.783 studies matching the keyword algorithm, 47 were considered. The following recommendations could be deduced: minimally invasive surgery is the recommended approach (LE 1a); a complete hernia sac dissection should be considered (LE 3b); extensive division of short gastric vessels cannot be recommended; however, limited dissection of the most upper vessels may be helpful for a floppy fundoplication (LE 1a); vagus nerve should be preserved (LE 3b); a dorso-ventral cruroplasty is recommended (LE 1b); routine fundoplication should be considered to prevent postoperative gastroesophageal reflux (LE 2b); posterior partial fundoplication should be favored over other forms of fundoplication (LE 1a); mesh augmentation is indicated in large HH with paraesophageal involvement (LE 1a).ConclusionThe current evidence mapping is a reasonable instrument based on the best evidence available to guide surgeons in determining optimal symptomatic and large HH repair.

Wrestling with evidence-based practice: An evidence mapping review of publication trends in the South African Journal of Occupational Therapy

Introduction: Occupational therapy research to support clinical decision-making must be responsive to local needs, illustrate our unique value to clients, communities and providers, and demonstrate efficacy for quality assurance and reimbursement. This article examines the publication trends in the South African Journal of Occupational Therapy (SAJOT) with the intention of contributing to dialogues about evidence-based practice. Methods: A mapping review was undertaken of articles published in the SAJOT from January 2009 to December 2021. All articles excepting commentaries, book reviews and editorials were included. Articles were categorised by year of publication, title, author, research approach, study design, practice area, research affiliation, and nature of authorship.Quantitative research articles were classified according to the Australian National Health and Medical Research Council (NHMRC) levels of evidence. Results: Of the 265 articles published in the 13-year period, slightly more took a quantitative approach (52.1%) comparedwith qualitative approaches (42.4%). Most quantitative studies were Level 111-2 studies (31.3%). Children and Youth was the practice area with the highest number of articles (34.8%) and the strongest evidence base. Conclusion: As occupational therapy continues to wrestle with EBP, further dialogue about a national occupational therapy research strategy to identify and harness enablers and explore and mitigate the barriers identified in this review, is recommended.
