Background: Systematic reviews involve searching multiple bibliographic databases to identify eligible studies. As this type of evidence synthesis is increasingly pursued, the use of various electronic platforms can help researchers improve the efficiency and quality of their research. We examined the accuracy and efficiency of commonly used electronic methods for flagging and removing duplicate references during this process. Methods: A heterogeneous sample of references was obtained by conducting a similar topical search in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and PsycINFO databases. References were de-duplicated via manual abstraction to create a benchmark set. The default settings were then used in Ovid multifile search, EndNote desktop, Mendeley, Zotero, Covidence, and Rayyan to de-duplicate the sample of references independently. Using the benchmark set as reference, the number of false-negative and false-positive duplicate references for each method was identified, and accuracy, sensitivity, and specificity were determined. Results: We found that the most accurate methods for identifying duplicate references were Ovid, Covidence, and Rayyan. Ovid and Covidence possessed the highest specificity for identifying duplicate references, while Rayyan demonstrated the highest sensitivity. Conclusion: This study reveals the strengths and weaknesses of commonly used de-duplication methods and provides strategies for improving their performance to avoid unintentionally removing eligible studies and introducing bias into systematic reviews. Along with availability, ease-of-use, functionality, and capability, these findings are important to consider when researchers are selecting database platforms and supporting software programs for conducting systematic reviews.

Matrix gla protein (MGP) is an important vitamin K-dependent inhibitor of vascular calcification. High levels of uncarboxylated, dephosphorylated MGP have been associated with vascular calcification and are responsive to vitamin K treatment. In this systematic review, we summarize the available evidence examining whether vitamin K supplementation improves surrogate measures of cardiovascular disease including artery and valve calcification, atherosclerosis and artery stiffening. Data from controlled trials of adults were obtained by searching Ovid MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and the Web of Science Core Collection. We identified nine randomized controlled trials for review, including trials of vitamin K₁ or vitamin K₂ supplementation, that assessed a surrogate measure of cardiovascular disease including arterial calcification, atherosclerosis or arterial stiffening. For each trial, the risk of bias was assessed applying Cochrane Collaboration methodology. The findings indicate that vitamin K does not consistently prevent progression of calcification, atherosclerosis or arterial stiffness. There may be some benefit in people with calcification at study entry. Studies were heterogenous, with relatively short follow-up and outcome measures were varied. While vitamin K supplementation clearly improves the carboxylation of dephosphoylated MGP, its role in mitigating vascular calcification is uncertain, based on current evidence.

Background: Many health sciences librarians are noticing an increase in demand for systematic review support. Developing a strategic approach to supporting systematic review activities can address commonly reported barriers and challenges including time factors, methodological issues, and supporting student-led projects.Case Presentation: This case report describes how a health sciences library at a mid-sized university developed and implemented a structured and defined systematic review service in order to build capacity for increased librarian support and to maximize librarians’ time and expertise. The process also revealed underlying collaboration challenges related to student-led systematic reviews and research quality concerns that needed to be addressed. The steps for developing a formal service included defining the librarian’s role and a library service model, building librarian expertise, developing documentation to guide librarians and patrons, piloting and revising the service model, marketing and promoting the service, and evaluating service usage.Conclusions: The two-tiered service model developed for advisory consultation and collaboration provides a framework for supporting systematic review activities that other libraries can adapt to meet their own needs. Librarian autonomy in deciding whether to collaborate on reviews based on defined and explicit considerations was crucial for maximizing librarians’ time and expertise and for promoting higher quality research. Monitoring service usage will be imperative for managing existing and future librarian workload. These data and tracking of research outputs from librarian collaborations may also be used to advocate for new librarian positions.

Introduction: While some families may experience poor mental health, substance use, and poor school performance due to service life, the usefulness and applicability of these research findings may be affected by how representative study participants are of the broader population. This article aims to examine how research on mental health and substance use defines a “military family” to understand if the current body of evidence reflects the increasing diversity of this population. Methods: A systematic search of academic articles was conducted in Ovid MEDLINE, Ovid Embase, Ovid PsycINFO, Ebsco CINAHL and ProQuest PILOTS using database-specific subject headings and keyword searches for ‘military’, ‘family’, ‘mental health’ and ‘substance use’. Sociodemographic and military characteristics of study participants were extracted to identify who was and was not included. Results: The most commonly represented family structure was the traditional, heteronormative family comprised of a male service member married to a female civilian with whom they have children. Military couples without children, dual-serving couples, families of LGBTQ personnel, unmarried and new relationships, single parents, male spouses/partners, Veterans not seeking Veterans Affairs (VA) services, and families with additional challenges were regularly not reflected in the research due to implicit or explicit exclusion from studies. Discussion: Research on mental health and substance use among the family members of service personnel continues to reflect the traditional, heteronormative family. Future studies should consider more inclusive definitions of family and creative approaches to recruitment to ensure research in this area reflects the experiences, needs, and strengths of an increasingly diverse military community.

Background and Objective: This review updates and expands on previous reviews of educational interventions for primary care providers (PCPs) involved in palliative and end-of-life care (PEoLC) and is the first to include early studies related to medical assistance in dying (MAiD). Methods: A comprehensive search strategy was conducted across five electronic databases to locate published interventional studies related to ongoing PEoLC and/or MAiD education for primary care professionals. A descriptive summary of results and a narrative discussion of common themes and comparisons are provided. Results: Thirty-seven studies met the inclusion criteria. The researchers found a myriad of interventions, including courses based, practical experience, mentoring, and workshops. The researchers categorized results by four domains: attitude, confidence, knowledge, and skills. Across domains, seven educational topics emerged: general care, interprofessional collaboration, nutrition, pain and symptom management, patient communication, and professional coping. Overall, studies employed various methodologies, but often relied on cross-sectionally measured self-assessment. Two articles were found that measured the impact of MAiD education. Conclusion: These findings suggest that PEoLC education can improve PCPs' perceived attitudes, confidence, knowledge, and skills across multiple areas of palliative care practice. While PCPs across studies valued educational interventions, the findings relating to the impact of PEoLC education on PCP's provision of effective PEoLC were unclear. However, most interventions resulted in enhanced confidence and knowledge. To date, there are only two studies that have examined MAiD educational programs. There is a need for studies of higher rigor with more emphasis on follow-up to clarify the impact training has on those involved in PEoLC and MAiD.
