Prioritizing future evidence needs for marine and freshwater mammal conservation action

AbstractMarine and freshwater mammals are increasingly threatened due to human activity. To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Using a systematically collated database of studies that test the effectiveness of actions to conserve marine and freshwater mammals, we investigated the gaps and biases in the available scientific evidence base. While there is a growing evidence base covering actions to address key threats (e.g. fisheries and bycatch) to marine and freshwater mammal populations, we identified large geographic and taxonomic biases. There was no relationship between the number of studies and marine mammal species per ecoregion and we found biases towards coastal areas of the Global North, with many regions and species having little or no evidence available. The number of studies per species did not correlate with (1) the threat level, (2) evolutionary distinctiveness or (3) the public ‘popularity’ of the study species. We also found a mismatch between actions tested and the actions suggested as needed in the International Union for the Conservation of Nature (IUCN) Red List. Several of these gaps and biases likely reflect the feasibility of researching marine mammal populations; many species can be difficult to access, with limited baseline information on populations and threats, and testing actions can require costly long‐term monitoring. Prioritizing the most cost‐effective conservation strategies for marine and freshwater mammal species will require a comprehensive evidence base on the effects of actions. Continuing to build the necessary baseline data, and focusing future research and funding towards the priority gaps identified in this study will be important to deliver this target.

Heatwaves, Hospitals, and Health System Resilience in England: A Qualitative Assessment (Summer 2019)

Abstract Background Frequent heatwaves challenge healthcare delivery in England, affecting patient safety and staff welfare. This study addresses the observational gap in how healthcare settings adapt to extreme weather. Methods We utilised a qualitative approach, conducting semi-structured interviews with fourteen NHS staff across England to explore experiences during the 2019 summer heatwave. Participants included clinical and non-clinical personnel, providing broad insights into operational challenges and adaptive strategies. Results The 2019 heatwave significantly disrupted service delivery, with variable staff awareness of the Heatwave Plan for England affecting responses. Key issues included managing infection control versus electric fan usage, impacting patient and staff comfort and safety. These conditions also led to an increase in hospital admissions. Conclusions The findings highlight the need for improved workforce training and strategic planning to enhance resilience to heat-related risks. Further research is essential to develop a comprehensive evidence base on the impacts and costs of heatwaves and to assess the effectiveness of adaptation strategies. This will support national health adaptation planning and emergency response. Key messages • Enhanced planning and training are crucial for health system resilience to heatwaves. • More research is needed to understand heatwave impacts and effective responses.

Optimising remote health workforce retention: protocol for a program of research

BackgroundNowhere is optimising healthcare staff retention more important than in primary health care (PHC) settings in remote Australia, where there are unacceptably high rates of staff burnout and turnover. Ensuing consequences for the remote health services and the community are acute – staffing shortfalls in clinics; organisational instability; excessive costs associated with frequent staff recruitment and orientation; diminished access to PHC for patients in need; and lack of continuity of patient care; all of which further entrench poor health outcomes for the community. Optimising remote healthcare staff retention is critical in order to provide high quality and continued PHC. Currently, however, there is paucity of knowledge to inform targeted and effective retention strategies in remote health services.This research program seeks to develop a stronger evidence base to understand (i) what retention strategies are effective in improving morale, job satisfaction, intention to remain in the job, and consequent length of service for remote healthcare staff; (ii) how best to ‘bundle’ these strategies for different health workforce groups; and (iii) how these ‘bundles’ work in different service contexts.MethodsThis paper describes a five-year implementation research program in partnership with twelve remote Aboriginal and Torres Strait Islander Community Controlled Health Services (ATSICCHS) in the Northern Territory and Queensland, Australia. Overall methodology follows a participatory action research approach which incorporates co-design and realist elements. The program comprises two broad phases involving evidence consolidation and synthesis (Phase 1), and co-design, implementation, and prospective evaluation of ‘bundles’ of retention strategies (Phase 2) to improve retention of healthcare staff in participating ATSICCHSs.DiscussionThis innovative research program has the potential to develop a comprehensive evidence base required to optimise health workforce retention in remote health services. This new evidence will strengthen understanding of what ‘bundles’ of retention strategies are effective, for which groups of employees, and how they work to improve staff retention.

The NAVigate-HPV Registry: A comprehensive biomarker evidence base for HPV-driven cancers.

e15045 Background: Human papillomavirus (HPV) is an oncogenic driver of several human cancers, including those of the anal canal, uterine cervix, and head and neck (predominantly oropharynx). Despite advancements in our understanding of HPV-related cancers, there remains an unmet need for a comprehensive biomarker-driven registry to establish correlations between biomarker detectability and clinicopathologic features in patients diagnosed and treated for HPV-driven cancers. To address this need, the NAVigate-HPV Registry has been established to systematically collect and analyze integrated biomarker and clinical data from many U.S. cancer centers. Methods: NavDx (Naveris, Inc.) is a clinically validated blood-based assay detecting circulating cell-free tumor tissue modified viral (TTMV)-HPV DNA. The NAVigate-HPV Registry is a web-based data platform based on a centrally IRB approved protocol. Participating investigators will include providers that order NavDx tests in the routine clinical care of their patients and agree to the terms and conditions for use of the registry. Eligible subjects will have or have had an HPV-driven cancer (with an initial focus on HPV-driven oropharynx cancer with confirmatory tissue testing) and have received one or more NavDx blood tests during routine clinical care. Clinical data and TTMV-HPV DNA scores will be collected at enrollment and defined intervals over five years or until death. Results: In the initial phase, the registry has enlisted participation and established a steering committee composed of a representative from each of 14 institutions. These institutions are geographically diverse centers ranging from community hospitals to clinics and academic medical facilities. An IRB protocol governing the registry will maintain ethical standards, ensuring compliance and ethical conduct throughout the registry process. Data extraction methods have been previously established to evaluate an initial cohort of 543 patients (Hanna GJ, Roof SA, et. al 2023). Conclusions: Naveris and collaborators have together successfully launched the NAVigate-HPV registry with the aim of creating a robust database linking tumor biomarker results from NavDx with clinical outcomes data for HPV-related cancers. The NAVigate-HPV database is expected to encompass more than 1,000 patients within 1 year and grow to > 5,000 patients within 5 years, serving as a powerful tool for precision cancer medicine in this patient cancer population. Establishing this registry will deepen insights into HPV-related cancers and advance diagnostic and therapeutic approaches to improve patient outcomes.

Do employability programmes in higher education improve skills and labour market outcomes? A systematic review of academic literature

ABSTRACT We conduct a systematic literature review of the academic literature on activities organised by Higher Education Institutions (HEIs) with the aim of improving skills associated with employability and facilitating labour market outcomes. The search resulted in 87 papers followed by an iterative evaluation of their relevance. Papers in the corpus were analysed using an evaluation research framework and classified in terms of the activities, outputs, and outcomes. The reviewed literature is centred on one of three stakeholders: HEIs, students or employers. It suggests all stakeholders value employability activities for similar reasons. Generally, they are seen as a vital part of HEI education programmes, facilitating the development of diverse skills that are desirable in the labour market as well as de-risking labour market entry for students and appointments for employers by alleviating information asymmetries. The evidence base is dominated by small-scale case studies and evaluations that are not sufficiently robust to infer about causal impacts of employability activities on students’ development and labour market outcomes. Moreover, the corpus is skewed towards studies of Work-Related Learning. We set out avenues for future research and argue for a comprehensive evidence base encompassing diverse forms of employability activities, such as larger scale ‘embedded employability’ activities; a more contextual understanding of employability as an interplay between individual and a particular labour market and education system; and a more robust evidence base tracking students from education into the labour market, allowing for selection effects and identifying heterogeneity of impacts across different activities and demographics.

Benefits, Harms, and Stakeholder Perspectives Regarding Opioid Therapy for Pain in Individuals With Metastatic Cancer: Protocol for a Descriptive Cohort Study.

Opioids are a key component of pain management among patients with metastatic cancer pain. However, the evidence base available to guide opioid-related decision-making in individuals with advanced cancer is limited. Patients with advanced cancer or cancer that is unlikely to be cured frequently experience pain. Opioids are a key component of pain management among patients with metastatic cancer pain. Many individuals with advanced cancer are now living long enough to experience opioid-related harm. Emerging evidence from chronic noncancer pain literature suggests that longer-term opioid therapy may have limited benefits for pain and function, and opioid-related harms are also a major concern. However, whether these benefits and harms of opioids apply to patients with cancer-related pain is unknown. This manuscript outlines the protocol for the "Opioid Therapy for Pain in Individuals With Metastatic Cancer: The Benefits, Harms, and Stakeholder Perspectives (BEST) Study." The study aims to better understand opioid decision-making in patients with advanced cancer, along with opioid benefits and harms, through prospective examination of patients' pain experiences and opioid side effects and understanding the decision-making by patients, care partners, and clinicians. This is a multicenter, prospective cohort study that aims to enroll 630 patients with advanced cancer, 20 care partners, and 20 clinicians (670 total participants). Patient participants must have an advanced solid cancer diagnosis, defined by the American Cancer Society as cancer that is unlikely to be cured. We will recruit patient participants within 12 weeks after diagnosis so that we can understand opioid benefits, harms, and perspectives on opioid decision-making throughout the course of their advanced cancer (up to 2 years). We will also specifically elicit information regarding long-term opioid use (ie, opioids for ≥90 consecutive days) and exclude patients on long-term opioid therapy before an advanced cancer diagnosis. Lived-experience perspectives related to opioid use in those with advanced cancer will be captured by qualitative interviews with a subset of patients, clinicians, and care partners. Our data collection will be grounded in a behavioral decision research approach that will allow us to develop future interventions to inform opioid-related decision-making for patients with metastatic cancer. Data collection began in October 2022 and is anticipated to end by November 2024. Upon successful execution of our study protocol, we anticipate the development of a comprehensive evidence base on opioid therapy in individuals with advanced cancer guided by the behavioral decision research framework. The information gained from this study will be used to guide interventions to facilitate opioid decisions among patients, clinicians, and care partners. Given the limited evidence base about opioid therapy in people with cancer, we envision this study will have significant real-world implications for cancer-related pain management and opioid-related clinical decision-making.

The Evolving Nature of Health Technology Assessment: A Critical Appraisal of NICE’s New Methods Manual

ObjectivesThe National Institute for Health and Care Excellence (NICE) recently completed a review of its methods for health technology assessment, involving a 2-stage public consultation. We appraise proposed methodological changes and analyze key decisions. MethodsWe categorize all changes proposed in the first consultation as “critical,” “moderate” or “limited” updates, considering the importance of the topic and the degree of change or the level of reinforcement. Proposals were followed through the review process, for their inclusion, exclusion, or amendment in the second consultation and the new manual. ResultsThe end-of-life value modifier was replaced with a new “disease severity” modifier and other potential modifiers were rejected. The usefulness of a comprehensive evidence base was emphasized, clarifying when nonrandomized studies can be used, with further guidance on “real-world” evidence developed separately. A greater degree of uncertainty was accepted in circumstances when evidence generation raised challenges, in particular for children, rare diseases, and innovative technologies. For some topics, such as health inequality, discounting, unrelated healthcare costs, and value of information, significant changes were possibly warranted, but NICE decided not to make any revisions at present. ConclusionMost of the changes to NICE’s health technology assessment methods are appropriate and modest in impact. Nevertheless, some decisions were not well justified and further research is needed on several topics, including investigation of societal preferences. Ultimately, NICE’s role of protecting National Health Services resources for valuable interventions that can contribute toward improving overall population health must be safeguarded, without accepting weaker evidence.

A scoping review of lesbian, gay, bisexual, transgender, queer, and intersex (LGBTQI+) people's health in India.

Amid incremental progress in establishing an enabling legal and policy environment for lesbian, gay, bisexual, transgender and queer-identified people, and people with intersex variations (LGBTQI+) in India, evidence gaps on LGBTQI+ health are of increasing concern. To that end, we conducted a scoping review to map and synthesize the current evidence base, identify research gaps, and provide recommendations for future research. We conducted a scoping review using the Joanna Briggs Institute methodology. We systematically searched 14 databases to identify peer-reviewed journal articles published in English language between January 1, 2010 and November 20, 2021, that reported empirical qualitative, quantitative or mixed methods data on LGBTQI+ people's health in India. Out of 3,003 results in total, we identified 177 eligible articles; 62% used quantitative, 31% qualitative, and 7% mixed methods. The majority (55%) focused on gay and other men who have sex with men (MSM), 16% transgender women, and 14% both of these populations; 4% focused on lesbian and bisexual women, and 2% on transmasculine people. Overall, studies reported high prevalence of HIV and sexually transmitted infections; multilevel risk factors for HIV; high levels of mental health burden linked to stigma, discrimination, and violence victimization; and non-availability of gender-affirmative medical care in government hospitals. Few longitudinal studies and intervention studies were identified. Findings suggest that LGBTQI+ health research in India needs to move beyond the predominant focus on HIV, and gay men/MSM and transgender women, to include mental health and non-communicable diseases, and individuals across the LGBTQI+ spectrum. Future research should build on largely descriptive studies to include explanatory and intervention studies, beyond urban to rural sites, and examine healthcare and service needs among LGBTQI+ people across the life course. Increased Indian government funding for LGBTQI+ health research, including dedicated support and training for early career researchers, is crucial to building a comprehensive and sustainable evidence base to inform targeted health policies and programs moving forward.

Movement behavior policies in the early childhood education and care setting: An international scoping review.

Meeting 24-h movement behavior guidelines for the early years is associated with better health and development outcomes in young children. Early childhood education and care (ECEC) is a key intervention setting however little is known about the content and implementation of movement behavior polices in this context. To inform policy development this international scoping review examined the prevalence, content, development and implementation of ECEC-specific movement behavior policies. A systematic literature search of published and gray literature since 2010 was conducted. Academic databases (EMBASE, Cinahl, Web of Science, Proquest, Scopus, EBSCO, PubMed) were searched. A Google search was undertaken and limited to the first 200 results. The Comprehensive Analysis of Policy on Physical Activity framework informed data charting. Forty-three ECEC policy documents met inclusion criteria. Most policies originated in the United States, were subnational and developed with government, non-government organizations and ECEC end-users. Physical activity was specified in 59% (30-180 min/day), sedentary time in 51% (15-60 min/day) and sleep in 20% (30-120 min/day) of policies. Daily outdoor physical activity was recommended (30-160 min/day) in most policies. No policy permitted screen time for children <2 years, with 20-120 min/day for children >2 years. Most policies (80%) had accompanying resources but few provided evaluation tools (e.g., checklists; action plan templates). Many policies had not been reviewed since the publication of 24-h movement guidelines. Movement behavior policies in the ECEC setting are often vaguely worded, missing a comprehensive evidence base, siloed in development and often not tailored for the 'real world.' A focus on evidence informed ECEC-specific movement behavior policies proportionally aligned with national/international 24-h Movement Behaviors Guidelines for the Early Years is needed.

Methods to appraise available evidence and adequacy of data from a systematic literature review to conduct a robust network meta-analysis of treatment options for patients with hospital-acquired or ventilator-associated bacterial pneumonia.

We aimed to determine if available evidence from a previously conducted systematic literature review was sufficient to conduct a robust network meta-analysis (NMA) using the International Society for Pharmacoeconomics and Outcomes Research Good Practice Task Force NMA study questionnaire to evaluate suitability, relevance, and credibility of available randomized-controlled trials (RCT) of antibacterial therapies for treatment of patients with hospital-acquired or ventilator-associated bacterial pneumonia (HABP/VABP). We assessed feasibility and reliability of an NMA for a connected network of RCTs, and then relevance and credibility of the connected network for informing decision-making. This previously conducted systematic literature review using Cochrane dual-reviewer methodology, Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and PICOTS (population, interventions, comparators, outcomes, timing, and setting) criteria identified 25 citations between 2001 and 2018; 18 were unique RCTs. Trial design characteristics, outcome definitions, assessment time points, and analyses populations varied across studies. Using "clinical response," an efficacy end point to health technology assessment agencies, we assessed potential network credibility, which collapsed from the overall data set to four studies and five interventions. This did not include closed loop(s) needed to assess consistency. Of the studies reporting clinical response, >70% of patients were ventilated at baseline with mean Acute Physiologic Assessment and Chronic Health Evaluation II scores from 14.7 to 17.5. Pseudomonas aeruginosa (range, 18.4-64.1%) and Klebsiella spp. (range, 1.6-49%) were the most common causative pathogens. We identified relevant RCTs for most standard-of-care agents approved for HABP/VABP, which provided a comprehensive evidence base. In summary, our appraisal of available evidence for the clinical response outcome among adult patients with HABP/VABP does not support the conduct of a scientifically robust and clinically meaningful NMA. Although this data is vital to registration, there are significant limitations in these trials for health technology assessments, payor decisions, guidelines, and protocol decisions.

Citationchaser: A tool for transparent and efficient forward and backward citation chasing in systematic searching.

Systematic searching aims to find all possibly relevant research from multiple sources, the basis for an unbiased and comprehensive evidence base. Along with bibliographic databases, systematic reviewers use a variety of additional methods to minimise procedural bias. Citation chasing exploits connections between research articles to identify relevant records for a review by making use of explicit mentions of one article within another. Citation chasing is a popular supplementary search method because it helps to build on the work of primary research and review authors. It does so by identifying potentially relevant studies that might otherwise not be retrieved by other search methods; for example, because they did not use the review authors' search terms in the specified combinations in their titles, abstracts, or keywords. Here, we briefly provide an overview of citation chasing as a method for systematic reviews. Furthermore, given the challenges and high resource requirements associated with citation chasing, the limited application of citation chasing in otherwise rigorous systematic reviews, and the potential benefit of identifying terminologically disconnected but semantically linked research studies, we have developed and describe a free and open source tool that allows for rapid forward and backward citation chasing. We introduce citationchaser, an R package and Shiny app for conducting forward and backward citation chasing from a starting set of articles. We describe the sources of data, the backend code functionality, and the user interface provided in the Shiny app.

Building climate resilience through nature-based solutions in Europe: A review of enabling knowledge, finance and governance frameworks

The European Union (EU) has firmly positioned itself as a global leader in promoting and implementing nature-based solutions (NBS). The recently released EU Biodiversity Strategy for 2030, Strategy on Adaptation to Climate Change, and Forest Strategy - all representing key pillars of the ambitious European Green Deal (EGD) - rely on NBS to both preserve and restore ecosystem integrity and increase climate resilience. Although research and policy in Europe have advanced the conceptualization and operationalization of NBS, a much wider adoption is needed to reach the ambitious goals of the EGD and fulfil its vision of transforming into a sustainable, climate-neutral, climate resilient, fair, and prosperous EU by 2050. In this paper, we review recent EU-supported research, policy, and practices to identify critical dimensions that still need to be addressed for greater uptake of NBS. While recognising the multiple societal challenges NBS can target, we build on the key messages from the ‘5th European Climate Change Adaptation conference ECCA 2021′ and focus our analysis on NBS for climate change adaptation and disaster risk reduction. We screen a wide range of NBS cases across the EU and identify-three core challenges to implementation: the lack of a comprehensive evidence base on the effectiveness of NBS to address targeted challenges; the need for a greater involvement of the private sector in financing NBS; and opportunities for enhancing stakeholder engagement in the successful design and implementation of NBS. We take these challenges as the starting point for a broader reflection and critical discussion on the role of i) knowledge, i) finance, including investments in NBS and divestments from nature-negative projects, and iii) governance and policy frameworks to enable the uptake of NBS. We conclude by identifying options for the EU to foster the uptake of NBS in research, policy and practice.

A preliminary estimate of the economic value of Iceland's terrestrial ecosystem services and opportunities for future research

Iceland is an understudied nation with respect to the quality, quantity and value of its ecosystem services, despite the growth of nature-based tourism and an economy reliant on abundant natural resources, especially fish stocks and renewable energy. This research reports on the preliminary outcome of an investigation to estimate the economic value of Iceland's ecosystem services (ES). The benefit transfer method is applied using the latest aggregate unit values from the Ecosystem Services Valuation Database, scaled to CORINE land cover types for Iceland. An estimate of 3,209,476 million ISK/year (approximately US $26.1 billion/year) is determined in 2019 prices, which is 1.08 times the size of Icelandic Gross Domestic Product and could be a low estimate due to the omission of cultural ES. Rather than being the final word on the value of Iceland's ecosystem services, this assessment should be viewed as an order of magnitude estimate, a useful starting point for considering the biomes and related ES of likely high economic value in Iceland, which in turn provides a basis for considering potential ES management issues of importance. The study discusses how economic valuation of Iceland's ecosystem services could provide useful information to decision-makers in a range of hotly discussed areas, including the determination of conservation policy, strategic energy management and sustainable land management. The results of this study also imply that there would be merit in conducting a national ES assessment for Iceland, which would integrate extensive stakeholder, biophysical and economic analyses to provide a comprehensive evidence base concerning the benefits supplied to society and how ES underpin the nation's economic prosperity.

Reimagining community relationships for organizational learning: a scoping review with implications for a learning health system

BackgroundCommunities represent a highly relevant source of knowledge with regard to not only healthcare performance but also sociocultural context, yet their role in learning health systems has not been studied. Situating the learning health system as an organization, this paper explores the phenomenon of organizational learning from or with communities (defined as one of ‘the people,’ such as a town, a specific patient group or another group directly receiving a healthcare service).Methods We conducted a scoping review to determine what is known about organizational learning from or with communities that the organization serves, and to contribute to a more comprehensive evidence base for building and operating learning health systems. In March 2019, we systematically searched six academic databases and grey literature, applying no date limits, for English language materials that described organizational learning in relation to knowledge transfer between an organization and a community. Numerous variables were charted in Excel and synthesized using frequencies and thematic analysis. We updated this search in August 2020.ResultsIn total, 42 documents were included in our analysis. We found a disproportionate emphasis on learning explicit knowledge from community rather than on tacit knowledge or learning in equal partnership with community. Our review also revealed inconsistently defined concepts, tenuously linked with their theoretical and empirical foundations. Our findings provide insight to understand the organization-community learning relationship, including motives and power differentials; types of knowledge to be learned; structures and processes for learning; and transformative learning outcomes.ConclusionsOur review makes a singular contribution to organizational learning literatures by drawing from diverse research disciplines such as health services, business and education to map what is known about learning from or with community. Broadly speaking, learning health systems literature would benefit from additional research and theory-building within a sociological paradigm so as to establish key concepts and associations to understand the nature of learning with community, as well as the practices that make it happen.

Learning from previous lockdown measures and minimising harmful biopsychosocial consequences as they end: A systematic review.

BackgroundInfectious outbreaks, most recently coronavirus disease 2019 (COVID-19), have required pervasive public health strategies, termed lockdown measures, including quarantine, social distancing, and closure of workplaces and educational establishments. Although evidence analysing immediate effects is expanding, repercussions following lockdown measures remain poorly understood. This systematic review aims to analyse biopsychosocial consequences after lockdown measures end according to short, medium, and long-term impacts.MethodsPubMed, Ovid MEDLINE, Embase, PsycInfo, Web of Science, and Scopus databases were searched from inception to January 12, 2021. Reference lists were manually reviewed. Eligible studies analysed biopsychosocial functioning after lockdown measures secondary to recent infectious outbreaks ended. Lockdown measures were defined as quarantine, isolation, workplace or educational closures, social or physical distancing, and national or local closure of public institutions deemed non-essential. Studies exclusively researching outcomes during lockdown measures, examined infectious participants, or analysed lockdown measures not pertaining to an infectious outbreak were excluded. Two independent reviewers extracted data and assessed bias with a third resolving discrepancies. Data was extracted from published reports with further information requested from authors where necessary. The mixed methods appraisal tool assessed study quality, languages were restricted to English, German, Italian, and French and narrative synthesis was applied.ResultsOf 5149 identified studies, 40 were eligible for inclusion. Psychological distress, economic repercussions, social, biological, and behavioural ramifications were observed. Short to medium-term effects comprised reactions relating to early trauma processing whereas medium to long-term repercussions manifested in maladaptive behaviours and mental health deterioration. Increased alcohol intake, stigmatisation, and economic effects were also identified consequences. High-risk groups included health care workers, children, elderly, inpatients, those with pre-existing psychiatric diagnoses, and socially isolated individuals.ConclusionsSupporting vulnerable groups and offering education, workplace modifications, financial, and social assistance may mitigate negative repercussions. Establishing a rapid and comprehensive evidence base appraising the efficacy of such interventions and identifying areas for development is essential. This review was limited by study heterogeneity and lack of randomisation in available literature. Given the unprecedented nature and progression of COVID-19, the relevance of previous outcomes remains uncertain.Protocol registrationPROSPERO registration CRD42020181134

Barriers and enablers to caregivers' responsive feeding behaviour: A systematic review to inform childhood obesity prevention.

Responsive infant feeding is a critical component of childhood obesity prevention. However, there is little guidance for caregivers on how to do this successfully. The first step to developing an intervention to promote responsive feeding is to systematically identify its barriers and enablers. Searches were conducted in CINAHL, Cochrane Library, Medline, Embase, PubMed, PsycINFO, Maternity, and Infant Care from inception to November 2020. All study designs were included if they reported a barrier or enabler to responsive feeding during the first 2 years of life. We used a "best fit" framework synthesis, with the Capacity, Opportunity, Motivation, and Behaviour (COM-B) model. The Mixed Method Appraisal Tool (MMAT) was used to assess study quality. Forty-three studies were included in the review. Barriers (n = 36) and enablers (n = 21) were identified across five COM-B domains: psychological capacity, physical and social opportunity, and reflective and automatic motivation. Enablers were recognition of infant feeding cues, feeding knowledge and family and friends. Caregiver attitude toward control of feeding was a barrier, together with health care professional advice about formula feeding and breastfeeding expectation. These barriers and enablers provide a comprehensive evidence base to guide intervention development to improve responsive feeding and prevent obesity across individual and population levels.

Dietary interventions with dietitian involvement in adults with chronic kidney disease: A systematic review

A comprehensive evidence base is needed to support recommendations for the dietetic management of adults with chronic kidney disease (CKD). The present study aimed to determine the effect of dietary interventions with dietitian involvement on nutritional status, well-being, kidney risk factors and clinical outcomes in adults with CKD. Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE, PsycINFO and EMBASE.com were searched from January 2000 to November 2019. Intentional weight loss and single nutrient studies were excluded. Risk of bias was assessed using the Cochrane risk-of-bias tool. Effectiveness was summarised using the mean difference between groups for each outcome per study. Twelve controlled trials (1906 participants) were included. High fruit and vegetable intake, as well as a multidisciplinary hospital and community care programme, slowed the decline in glomerular filtration rate in adults with stage 3-4 CKD. Interventions addressing nutrition-related barriers increased protein and energy intake in haemodialysis patients. A Mediterranean diet and a diet with high n-3 polyunsaturated fatty acids improved the lipid profile in kidney transplant recipients. A limited number of studies suggest benefits as a result of dietary interventions that are delivered by dietitians and focus on diet quality. We did not identify any studies that focussed on our primary outcome of nutritional status or studies that examined the timing or frequency of the nutritional assessment. This review emphasises the need for a wider body of high-quality evidence to support recommendations on what and how dietetic interventions are delivered by dietitians for adults with CKD.

Evidence-based practice of stereotactic radiosurgery: Outcomes from an educational course for neurosurgery and radiation oncology residents.

Background: As the field of brain and spine stereotactic radiosurgery (SRS) continues to grow, so will the need for a comprehensive evidence base. However, it is unclear to what degree trainees feel properly equipped to use SRS. We assess the perceptions and comfort level reported by neurosurgery and radiation oncology residents concerning the evidence-based practice of SRS.Methods: A continuing medical education (CME) course provided peer-reviewed updates regarding treatment with intracranial and spinal SRS. Presentations were given by neurosurgery and radiation oncology residents with mentorship by senior faculty. To gauge perceptions regarding SRS, attendees were surveyed. Responses before and after the course were analyzed using the Fisher’s exact test in R statistical software.Results: Participants reported the greatest knowledge improvements concerning data registries (P < 0.001) and clinical trials (P = 0.026). About 82% of all (n = 17) radiation oncology and neurosurgery residents either agreed or strongly agreed that a brain and spine SRS rotation would be beneficial in their training. However, only 47% agreed or strongly agreed that one was currently part of their training. In addition, knowledge gains in SRS indications (P = 0.084) and ability to seek collaboration with colleagues (P = 0.084) showed notable trends.Conclusion: There are clear knowledge gaps shared by potential future practitioners of SRS. Specifically, knowledge regarding SRS data registries, indications, and clinical trials offer potential areas for increased educational focus. Furthermore, the gap between enthusiasm for increased SRS training and the current availability of such training at medical institutions must be addressed.
