Pembrolizumab plus chemotherapy for first-line treatment of advanced triple-negative breast cancer.

Aim: A systematic review and network meta-analysis (NMA) was performed to evaluate the efficacy of first-line treatments for locally recurrent unresectable or metastatic triple-negative breast cancer (TNBC) patients. Materials & methods: Databases were searched for randomized controlled trials evaluating first-line treatments for locally recurrent unresectable or metastatic TNBC patients. NMA was performed to estimate relative treatment effects on overall and progression-free survival between pembrolizumab + chemotherapy and other interventions. Results: NMA including eight trials showed that the relative efficacy of pembrolizumab + chemotherapy was statistically superior to that of other immunotherapy- or chemotherapy-based treatment regimens. Conclusion: Pembrolizumab + chemotherapy confers benefits in survival outcomes versus alternative interventions for the first-line treatment of locally recurrent unresectable or metastatic TNBC patients.

Clinical value of initial treatments for patients with advanced triple-negative breast cancerWhat is this article about? Around 15% of breast cancer patients have the triple-negative breast cancer (TNBC) subtype, which has the worst prognosis. Treatments targeting the immune system, such as pembrolizumab, were recently found to improve the outcomes of patients with cancer that is at an advanced stage or resistant to standard therapies. However, clinical trials evaluating the efficacy of cancer treatments typically compare only two alternative treatments. Therefore, we conducted this study to understand the relative efficacy of several commonly used initial treatments for advanced TNBC by indirectly comparing the results of all available clinical trials that were sufficiently similar. We identified trials by systematically searching the medical literature and analyzed the results of several clinical trials together to estimate the efficacy of pembrolizumab + chemotherapy compared with several other initial treatment regimens for patients with advanced TNBC.What were the results? We identified eight randomized controlled trials evaluating treatment regimens containing chemotherapeutic or immunotherapeutic agents in patients with previously untreated advanced TNBC. Considering all these trials together, pembrolizumab + chemotherapy was found to prolong patient survival to a greater extent than several other treatment regimens including carboplatin, docetaxel, paclitaxel, nab-paclitaxel/paclitaxel, bevacizumab + paclitaxel, ixabepilone + paclitaxel and ixabepilone + bevacizumab depending on the specific set of trials analyzed.What do the results of the study mean? These results indicate that pembrolizumab + chemotherapy has beneficial effects on patient survival compared with other initial treatment regimens for patients with advanced TNBC.

Clinical outcomes for previously treated patients with advanced biliary tract cancer: a meta-analysis.

Aim: A systematic review and meta-analysis were performed to evaluate the efficacy of treatments for previously treated advanced biliary tract cancer (BTC) patients. Materials & methods: Databases were searched for studies evaluating treatments for advanced (unresectable and/or metastatic) BTC patients who progressed on prior therapy. Pooled estimates of objective response rate (ORR), median overall survival (OS) and median progression-free survival (PFS) were calculated using random effects meta-analysis. Results: Across 31 studies evaluating chemotherapy or targeted treatment regimens in an unselected advanced BTC patient population, pooled ORR was 6.9%, median OS was 6.6 months and median PFS was 3.2 months. Conclusion: The efficacy of conventional treatments for previously treated advanced BTC patients is poor and could be improved by novel therapies.

What is this article about? Most patients with biliary tract cancer are identified with advanced disease, and almost all go through a worsening of the disease after their first treatment. For patients who go on to receive their next treatment, current guidelines are unclear regarding the best treatment choice. Therefore, we examined the available medical literature and performed an analysis of multiple studies to calculate overall estimates of the clinical value of standard treatments for these patients. Our goal was to develop a benchmark against which to compare the clinical value of new treatments that are currently being assessed in clinical trials. What were the results? We identified 31 studies assessing standard treatments (involving chemotherapy or molecularly targeted treatments) in previously treated advanced biliary tract cancer patients. Across these studies, the objective tumor response rate was 6.9%, median overall survival was 6.6 months and median progression-free survival was 3.2 months. What do the results of the study mean? These results indicate that there is limited clinical value of standard treatments for patients with advanced biliary tract cancer whose disease worsened after first treatment. This medical need could potentially be met by new treatments, such as immunotherapies that restore the immune system's ability to attack cancer cells and thereby prolong patient survival.

Chronic cough: more than just a persistent cough: a systematic literature review to understand the impact of chronic cough on quality of life.

PURPOSE: Chronic cough (CC), defined as a cough persisting ≥ 8 weeks, can have a substantial negative impact on health-related quality of life (HRQoL). This is exacerbated by challenges with timely diagnosis and a lack of approved therapies. A systematic literature review (SLR) was conducted to identify evidence on HRQoL and health state utility values associated with refractory CC or unexplained CC. METHODS: Electronic database searches were supplemented with searches of conference proceedings and health technology assessment body websites. Two independent reviewers assessed all citations for inclusion based on predefined inclusion/exclusion criteria. Key inclusion criteria were patient populations with CC and reporting of patient-reported outcomes or utilities using generic or disease-specific measures. RESULTS: Following screening, 65 studies were identified for inclusion in the SLR. Of these, 23 studies assessed HRQoL among patients with CC who were not treated or treated with unspecified interventions, and 42 studies in patients who were treated with specified interventions. The studies indicated a substantial decrement to HRQoL as a result of CC, characterized by generic and disease-specific patient-reported outcome measures. HRQoL was impacted across multiple domains, including physical, psychological, and social functioning. The studies also demonstrated the potential for treatments to have a significant positive impact on HRQoL. CONCLUSIONS: CC can substantially affect HRQoL in patients, across physical, psychological, and social domains. Although treatments can improve HRQoL in these patients, the available evidence is limited. There remains an unmet need for approved pharmacological treatments to alleviate CC and improve HRQoL for these patients.

Neoadjuvant immunotherapy and chemotherapy regimens for the treatment of high-risk, early-stage triple-negative breast cancer: a systematic review and network meta-analysis.

BACKGROUND: Patients with triple-negative breast cancer (TNBC) are generally younger and more likely to experience disease recurrence and have the shortest survival among all breast cancer patients. Recently, neoadjuvant delivery of the programmed cell death protein-1 inhibitor pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab was approved for patients with high-risk, early-stage TNBC, but this treatment regimen has not been evaluated in head-to-head trials with other neoadjuvant treatment regimens. Therefore, the objective of this study was to estimate the relative efficacy of neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab versus other neoadjuvant treatments for early-stage TNBC through a systematic review and network meta-analysis (NMA). METHODS: EMBASE, MEDLINE, Cochrane Central Register of Controlled Trials, conference abstracts, and clinical trial registries were searched for randomized controlled trials evaluating neoadjuvant treatments for early-stage TNBC. NMA was performed to estimate relative treatment effects among evaluated interventions. RESULTS: Five trials met the inclusion criteria and were included in the NMA. The relative efficacy of neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab was favorable to paclitaxel followed by anthracycline + cyclophosphamide in terms of pathologic complete response (pCR), event-free survival (EFS), and overall survival; paclitaxel + carboplatin followed by anthracycline + cyclophosphamide in terms of pCR and EFS; paclitaxel + bevacizumab followed by anthracycline + cyclophosphamide + bevacizumab in terms of pCR; and paclitaxel + carboplatin + veliparib followed by anthracycline + cyclophosphamide in terms of EFS. CONCLUSIONS: Neoadjuvant pembrolizumab + chemotherapy followed by adjuvant pembrolizumab confers benefits in response and survival outcomes versus alternative neoadjuvant treatments for early-stage TNBC.

Understanding the economic burden of chronic cough: a systematic literature review.

Chronic cough (CC) is associated with high healthcare resource utilization (HCRU) due to challenges in diagnosis and treatment and is anticipated to have a substantial economic impact. This systematic literature review (SLR) sought to identify evidence on the cost-effectiveness of treatments and the economic burden associated with CC. Electronic database searches were supplemented with searches of conference proceedings and health technology assessment body websites. Two independent reviewers assessed all citations for inclusion based on predefined inclusion/exclusion criteria. Key inclusion criteria were patient population with CC, and outcomes related to cost-effectiveness and HCRU and costs. After screening, one cost-effectiveness analysis was identified, alongside eight studies reporting HCRU and costs related to CC. Though evidence was limited, studies suggest that patients with CC incur higher costs and use more resources than those with acute cough. Types of resource use reported included healthcare contacts and prescriptions, diagnostic tests, referrals and specialist evaluations, and treatment use. There is a paucity of literature on HCRU and costs in CC, and very limited cost-effectiveness analyses. The economic burden appears higher in these patients however, without direct comparison to the general population it is difficult to determine the total impact. The increased burden is expected to be a result of the challenges with diagnosis and lack of approved treatments. However, limited conclusions can be drawn in the absence of further data. Future studies should endeavor to quantify the HCRU and cost attributable to patients with CC.

Domains of professional practice: analysis of publications in the Journal of the Medical Library Association from 2010 to 2019.

The Medical Library Association (MLA) has defined 7 domain hubs aligning to different areas of information professional practice. To assess the extent to which content in the Journal of the Medical Library Association (JMLA) is reflective of these domains, we analyzed the magnitude of JMLA articles aligning to each domain hub over the last 10 years. Bibliographic records for 453 articles published in JMLA from 2010 to 2019 were downloaded from Web of Science and screened using Covidence software. Thirteen articles were excluded during the title and abstract review because they failed to meet the inclusion criteria, resulting in 440 articles included in this review. The title and abstract of each article were screened by two reviewers, each of whom assigned the article up to two tags corresponding to MLA domain hubs (i.e., information services, information management, education, professionalism and leadership, innovation and research practice, clinical support, and health equity & global health). These results inform the MLA community about our strengths in health information professional practice as reflected by articles published in JMLA.

Bicycle handlebar injuries - a systematic review of pediatric chest and abdominal injuries.

OBJECTIVE: The severity of handlebar injuries can be overlooked due to subtle signs and wide range of associated internal injuries. Our objective was to describe thoracoabdominal injuries due to bicycle handlebars and their outcomes in children. METHODS: Articles that reported thoracoabdominal injuries were identified from database conception to March 3, 2019 using PubMed, EMBASE, Cochrane Library, CINHAHL Complete, Web of Science and Scopus. A systematic review of studies of thoracoabdominal handlebar injuries in children ≤21 years on human-powered bicycles in English was performed. Information on demographics, clinical features, injuries, interventions and outcomes was noted. RESULTS: A total of 138 articles were identified from 1952 to 2019. There were 1072 children (males, 85.1%) and 1255 thoracoabdominal injuries. Mean age was 9.7 ± 3.3 years old. Common clinical features included abdominal pain and guarding, vomiting, fever and a handlebar imprint. The liver was the most frequently injured organ. Surgery was performed in 338 children with a mean age of 10.0 ± 3.3 years. Twenty-seven children (2.5%) were discharged and returned due to worsening symptoms, of whom 23 (85.2%) required surgery. Thirty-one children (2.9%) transferred to a higher level of care due to injury severity. Two deaths were reported. CONCLUSION: Bicycle handlebars can cause significant thoracoabdominal injuries. Presence of abdominal pain, vomiting, fever or a circular imprint on the chest or abdomen should prompt further workup. Future studies on diagnostic modalities and best practices are needed to lower the chance of missed injuries.

Treatment of Self-Harm Scars: A Scoping Review.

BACKGROUND: Self-harm scars are a consequence of deliberate self-injury, serving as a visual reminder for involved individuals. Patients often reach out to their providers seeking treatment for their scars. However, there is currently no standard for treating self-harm scars, because multiple options are being explored. OBJECTIVE: A scoping review was conducted to identify and characterize the body of literature on different treatments for self-harm scars, including surgical, laser, and vitamin A management. METHODS: Thorough literature searches were conducted in PubMed/MEDLINE, EMBASE, and CINAHL Complete. The search strategy was designed and implemented by a medical librarian. RESULTS: Of 510 retrieved articles, 4 described laser treatments, 8 described surgical treatments, and 2 described vitamin A treatments. CONCLUSION: A multidisciplinary approach is critical for the selection and outcome of the treatment of self-harm scars.

Insights and opinions of readers of the Journal of the Medical Library Association.

The Journal of the Medical Library Association (JMLA) conducted a readership survey in 2020 to gain a deeper understanding of our readers, their reading habits, and their satisfaction with JMLA's content, website functionality, and overall quality. A total of 467 readers responded to the survey, most of whom were librarians/information specialists (85%), worked in an academic (62%) or hospital/health care system (27%) library, and were current Medical Library Association members (80%). Most survey respondents (46%) reported reading JMLA articles on a quarterly basis. Over half of respondents (53%) said they used social media to follow new research or publications, with Twitter being the most popular platform. Respondents stated that Original Investigations, Case Reports, Knowledge Syntheses, and Resource Reviews articles were the most enjoyable to read and important to their research and practice. Almost all respondents reported being satisfied or very satisfied (94%) with the JMLA website. Some respondents felt that the content of JMLA leaned more toward academic librarianship than toward clinical/hospital librarianship and that there were not enough articles on collection management or technical services. These opinions and insights of our readers help keep the JMLA editorial team on track toward publishing articles that are of interest and utility to our audience, raising reader awareness of new content, providing a website that is easy to navigate and use, and maintaining our status as the premier journal in health sciences librarianship.

Creating a more inclusive journal: the Journal of the Medical Library Association's evolving process for selecting editorial board members.

The Journal of the Medical Library Association (JMLA) selects new editorial board members every year. In the spring of 2021, JMLA used a new process for reviewing and selecting applicants for the limited number of open editorial board positions. This reevaluation of the selection process was spurred by a desire to create a more diverse and representative board. Changes to the procedures for selecting new editorial board members included having an open call for editorial board members, creating an application form, creating a selection committee to screen applicants, creating a form for the selection committee to extract data from applications, and creating a two-step process for screening and then selecting board members. As part of construction of this new process, areas for continued improvement were also identified, such as refining the application form to allow more specific answers to areas of interest to the selection committee. The newly created selection process for editorial board members constitutes a significant change in JMLA processes; however, more can be done to build on this work by further refining the selection process and ensuring that new members are selected in a transparent and streamlined manner.

Systematic Reviews of Clinical Benefits of Exoskeleton Use for Gait and Mobility in Neurologic Disorders: A Tertiary Study.

OBJECTIVE: To describe systematic reviews (SRs) of the use of exoskeletons for gait and mobility by persons with neurologic disorders and to evaluate their quality as guidance for research and clinical practice. DATA SOURCES: PubMed, EMBASE, Web of Science, CINAHL Complete, PsycINFO, Cochrane Database of Systematic Reviews, PEDro, and Google Scholar were searched from database inception to January 23, 2018. STUDY SELECTION: A total of 331 deduplicated abstracts from bibliographic database and ancestor searching were independently screened by 2 reviewers, resulting in 109 articles for which full text was obtained. Independent screening of those 109 articles by 2 reviewers resulted in a final selection of 17 SRs. DATA EXTRACTION: Data were extracted by 1 reviewer using a pretested Excel form with 158 fields and checked by a second reviewer. Key data included the purpose of the SR, methods used, outcome measures presented, and conclusions. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses and A MeaSurement Tool to Assess Systematic Reviews version 2 were used to evaluate reporting and methodological quality, respectively, of the SRs. DATA SYNTHESIS: The SRs generally were of poor methodological and reporting quality. They failed to report some information on patients (eg, height, weight, baseline ambulatory status) and interventions (eg, treatment hours or sessions planned and delivered) that clinicians and other stakeholders might want to have, and often failed to notice that the primary studies duplicated subjects. CONCLUSIONS: Published SRs on exoskeletons have many weaknesses in design and execution; clinicians, researchers, and other stakeholders should be cautious in relying on them to make decisions on the use of this technology. Future primary and secondary studies need to address the multiple methodological limitations.

Racial, gender, sexual, and disability identities of the Journal of the Medical Library Association's editorial board, reviewers, and authors.

The Journal of the Medical Library Association (JMLA) recently issued a call for submissions that recognize and address social injustices; speak to diversity, equity, and inclusion in our workforce and among our user populations; and share critical perspectives on health sciences librarianship as well as those on any topic within JMLA's scope written by authors who are Black, Indigenous, or People of Color. We also committed to creating more equitable opportunities for authors, reviewers, and editorial board members from marginalized groups. As part of this effort, we conducted a demographic survey of all individuals who served as a member of the JMLA editorial board or reviewer or had submitted a manuscript to JMLA between 2018 and 2020. We found that most survey respondents are white, heterosexual, women and do not identify with a disability, meaning that JMLA is missing out on a diversity of perspectives and life experiences that could improve the journal's processes and policies, enrich its content, and accelerate the research and practice of health sciences librarianship. Therefore, to avoid perpetuating or aggravating systemic biases and power structures in scholarly publishing or health sciences librarianship, we pledge to take concrete steps toward making JMLA a more diverse and inclusive journal.

Striving for equity: An update from the Journal of the Medical Library Association.

In 2020, the Journal of the Medical Library Association (JMLA) launched an initiative aimed at providing more equitable opportunities for authors, reviewers, and editorial team members. This editorial provides an update on the steps we have taken thus far to empower authors, increase the diversity of our editorial team, and make equity-minded recommendations to the Medical Library Association.

Report from the Medical Library Association's InSight Initiative Summit 3: Bridge Building: What Bridges to Build and How.

At the Medical Library Association's Insight Initiative Summit 3, held June 12-13, 2019, academic and hospital librarians joined with publishing industry partners to identify vexing problems in publishing and accessing health sciences information. Through a mixture of panel discussions with health sciences faculty, librarians, and information providers; small-group problem-solving exercises; and large-group consensus-building activities, the summit program invited participants to appreciate each other's viewpoints and propose a collaborative project leading to tangible outcomes that could ultimately benefit end users. Several vexing problems were identified, including poor communication and mistrust between librarians and publishers, complexities in product pricing structures and licenses, and users' difficulties in accessing and using vetted information resources. However, librarians and publishers agreed that building a better shared understanding of users' needs and behavior would be the most useful bridge toward regaining trust, establishing more effective partnerships, and designing and delivering quality information resources that are easily accessible and maximally useful to health sciences researchers, educators, clinicians, and students.

This editorial reflects on the state of JMLA in 2020 by describing our editorial team and volume of submissions, highlighting recent initiatives that strengthen the journal's position in the profession, and sharing future plans to enrich JMLA's content and promote open science. Committed to ending structural racism and other inequities in the field, we also issue an ongoing call for submissions pertaining to social justice and critical perspectives on health sciences librarianship.

Concise Review: Regulatory Influence of Sleep and Epigenetics on Adult Hippocampal Neurogenesis and Cognitive and Emotional Function.

Neural stem and progenitor cells continue to generate new neurons in particular regions of the brain during adulthood. One of these neurogenic regions is the dentate gyrus (DG) of the hippocampus, which plays an important role in cognition and emotion. By exploiting this innate neuronal regeneration mechanism in the DG, new technologies have the potential to promote resistance to or recovery from brain dysfunction or degeneration. However, a deeper understanding of how adult DG neurogenesis is regulated by factors such as sleep and epigenetic modifications of gene expression could lead to further breakthroughs in the clinical application of neural stem and progenitor cells. In this review, we discuss the functions of adult-born DG neurons, describe the epigenetic regulation of adult DG neurogenesis, identify overlaps in how sleep and epigenetic modifications impact adult DG neurogenesis and memory consolidation, and suggest ways of using sleep or epigenetic interventions as therapies for neurodegenerative and psychiatric disorders. By knitting together separate strands of the literature, we hope to trigger new insights into how the functions of adult-generated neurons are directed by interactions between sleep-related neural processes and epigenetic mechanisms to facilitate novel approaches to preventing and treating brain disorders such as depression, post-traumatic stress disorder, and Alzheimer's disease.

Report from the Medical Library Association's InSight Initiative Summit 2: Meeting the Evolving Information Needs of Library Stakeholders.

At the Medical Library Association's InSight Initiative Summit 2, held September 27-28, 2018, academic and hospital librarians joined with publishing industry partners to develop a deeper shared understanding of technology- and social interaction-driven changes in how health sciences researchers and clinicians discover and consume information in their fields. Through a mixture of keynote talks, a panel discussion with health care professionals, and small-group problem-solving exercises, the summit program invited participants to collaboratively develop strategies for helping users recognize the value of curated or peer-reviewed content obtained through institutional access channels. Themes of the summit included the existence of different user modes of information discovery and access, user reliance on professional societies and Twitter as information sources, the extent to which smartphones are used to find medical information, the importance of inducing disorienting dilemmas in library users that cause them to recognize librarians as true partners in information seeking and research, the dangers of depending on non-curated information, and the need for publishers and librarians to work together to ease barriers to access and enrich the user experience.

Announcing the Journal of the Medical Library Association's data sharing policy.

As librarians are generally advocates of open access and data sharing, it is a bit surprising that peer-reviewed journals in the field of librarianship have been slow to adopt data sharing policies. Starting October 1, 2019, the Journal of the Medical Library Association (JMLA) is taking a step forward and implementing a firm data sharing policy to increase the rigor and reproducibility of published research, enable data reuse, and promote open science. This editorial explains the data sharing policy, describes how compliance with the policy will fit into the journal's workflow, and provides further guidance for preparing for data sharing.
