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.

What 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.

Medical student program to learn from families experiencing developmental disabilities.

Patients and families experiencing developmental disabilities (DDs) may lack trust in physicians due to negative experiences in healthcare. DDs include conditions impairing physical, learning, language, or behavior areas, beginning during the developmental period and impacting daily functioning ('Developmental Disabilities'). Medical students generally do not receive standard training to effectively communicate with and diagnose patients with DDs. ARIE is a program for medical students to meet and learn from these patients and their families. Students learn about these families' experiences during home visits, guided by standardized interview questions and surveys about families' trust in physicians. Families did not appear to strongly trust physicians, with no significant changes after the program. Families shared they experienced physicians' lack of empathy and knowledge when caring for patients with DDs. Families wanted future physicians to be empathetic and informed when treating children with disabilities. Students reported increased comfort and confidence in interacting with patients with DDs as well as their families after completing the training program. Implementing a service-learning model focused on DDs at other medical schools, incorporating training with communication techniques and home visits, can increase students' confidence and experiences when engaging with patients with DDs and their families.

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.

Clinical Outcomes of PD-1/PD-L1 Inhibitors Among Patients With Advanced or Metastatic Non-Small Cell Lung Cancer With BRAF, ERBB2/HER2, MET , or RET Alterations: A Systematic Literature Review.

The therapeutic landscape for patients with advanced or metastatic non-small cell lung cancer (NSCLC) is rapidly evolving due to advances in molecular testing and the development of new targeted therapies and immunotherapies. However, the efficacy of programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors in advanced or metastatic patients with NSCLC whose tumors harbor BRAF V600E mutation, HER2/ERBB2 alteration, MET exon 14 skipping mutation, or RET rearrangement is not completely understood. A systematic literature review was performed to summarize evidence from clinical trials and observational studies on objective response rate, progression-free survival, and overall survival in patients whose tumors express these biomarkers and who were treated with PD-1/PD-L1 inhibitors. Searches of Embase, MEDLINE, conference abstracts, and a clinical trial registry identified a total of 12 unique studies: 4 studies included patients with BRAF V600E mutation, 6 studies included patients with HER2/ERBB2 alteration, 7 studies included patients with MET exon 14 skipping mutation, and 5 studies included patients with RET rearrangement. Across studies, there was heterogeneity in treatment and patient characteristics and a lack of reporting on many important predictive and prognostic factors, including treatment regimens, patients' line of therapy, and tumor PD-L1 expression, which may explain the wide variation in objective response rate, progression-free survival, and overall survival across studies. Therefore, additional studies prospectively evaluating clinical outcomes of PD-1/PD-L1 inhibitors among patients with advanced or metastatic NSCLC whose tumors harbor emerging predictive or prognostic biomarkers are needed to determine whether this class of immunotherapy can provide additional survival benefits for these patients.

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.

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.

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.

Approaches and geographical locations of respectful maternity care research: A scoping review.

BACKGROUND: Peripartum mistreatment of women contributes to maternal mortality across the globe and disproportionately affects vulnerable populations. While traditionally recognized in low/low-middle-income countries, the extent of research on respectful maternity care and the types of mistreatment occurring in high-income countries is not well understood. We conducted a scoping review to 1) map existing respectful maternity care research by location, country income level, and approach, 2) determine if high-income countries have been studied equally when compared to low/low-middle-income countries, and 3) analyze the types of disrespectful care found in high-income countries. METHODS: A systematic search for published literature up to April 2021 using PubMed/MEDLINE, EMBASE, CINAHL Complete, and the Maternity & Infant Care Database was performed. Studies were included if they were full-length journal articles, published in any language, reporting original data on disrespectful maternal care received from healthcare providers during childbirth. Study location, country income level, types of mistreatment reported, and treatment interventions were extracted. This study was registered on PROSPERO, number CRD42021255337. RESULTS: A total of 346 included studies were categorized by research approach, including direct labor observation, surveys, interviews, and focus groups. Interviews and surveys were the most common research approaches utilized (47% and 29% of all articles, respectively). Only 61 (17.6%) of these studies were conducted in high-income countries. The most common forms of mistreatment reported in high-income countries were lack of informed consent, emotional mistreatment, and stigma/discrimination. CONCLUSIONS: Mapping existing research on respectful maternity care by location and country income level reveals limited research in high-income countries and identifies a need for a more global approach. Furthermore, studies of respectful maternity care in high-income countries identify the occurrence of all forms of mistreatment, clashing with biases that suggest respectful maternity care is only an issue in low-income countries and calling for additional research to identify interventions that embrace an equitable, patient-centric empowerment model of maternity care.

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.

Efficacy analysis of different FLT3 inhibitors in patients with relapsed/refractory acute myeloid leukemia and high-risk myelodysplastic syndrome.

Several FLT3 inhibitors(i) are available to treat relapsed/refractory (R/R) FLT3-internal tandem duplicated acute myeloid leukemia (AML). This study analyzes the efficacies of various FLT3i (types 1 and 2) tested in clinical trials in treating R/R AML and high-risk myelodysplastic syndromes (HR-MDS). PubMed and EMBASE databases were searched for single/double-arm phase I/II/III R/R AML or HR-MDS clinical trials published between 1/1/2000 and 6/1/2021. The outcomes studied were composite response rate (CRc) and overall response rate (ORR). Toxicities were compared based on the organ system. The 28 studies analyzed had 1927 patients. The pooled ORR and (CRc) for all FLT3i were 53% (95% CI, 43%-63%) and 34% (95% CI, 26%-44%). Pooled ORR and CRc were 37% (95% CI, 25%-51%) and 35% (95% CI, 21%-52%) for type 1 and 58% (95% CI, 43%-71%) and 38% (95% CI, 27%-50%) for type 2, respectively. Gastrointestinal (GI) and hematological toxicity occurred in 22% (95% CI, 19%-25.4%) and 74.6% (95% CI, 70%-79%) with type 1 and 13.9% (95% CI, 12%-16%) and 57.7% (95% CI, 54.6%-60.8%) with type 2 FLT3i. QTc prolongation occurred in 2.06% (95% CI, 1.03%-3.65%) with type 1 and 7% (95% CI, 5.3%-9%) with type 2 FLT3i. Type 2 FLT3i had less GI toxicity but more QTc prolongation. Prospective studies are needed to compare the efficacy of type 1 and 2 FLT3i.

Timing of embolic phenomena after hydrogen peroxide exposure - a systematic review.

INTRODUCTION: Hydrogen peroxide ingestions cause significant morbidity and mortality due to oxygen gas emboli and are treatable with hyperbaric oxygen therapy. Recommendations for observation are based on small case series. OBJECTIVES: The aim of this systematic review is to define the time of onset of embolic phenomena after hydrogen peroxide exposure and to describe the proportion of patients who received hyperbaric oxygen therapy. METHODS: Cases from a systematic literature search were combined with those from a prior study that used data derived from the American Association of Poison Control Centers National Poison Data System. Air-gas emboli were defined as embolic phenomena (stroke, myocardial infarction, obstructive shock) potentially reversed with hyperbaric oxygen therapy. Simple counts, mean, and interquartile range were used for description and comparisons. RESULTS: A total of 766 records were identified in the literature search. Three-hundred and eighty-three duplicate records were identified and removed. Of the 383 remaining records, 156 met inclusion criteria; 88 were excluded based on predetermined criteria yielding 68 records with 85 unique cases. Forty-one cases were extracted from the 2017 National Poison Data System study resulting in a total of 126 cases for analysis. Case descriptions: We analyzed these 126 cases and documented 213 discrete clinical events, excluding deaths. There were 108 high-concentration exposures, 10 low-concentration exposures, and 8 were unknown. Thirty-five cases were intentional ingestions but not for self-harm, and 84 were unintentional or accidental. Only 4 cases were for self-harm, and there were 23 pediatric cases. There were 99 air-gas emboli reported in 78 patients. Time to onset: The time to onset of air-gas embolic was documented in 70/78. Time to symptom onset ranged from immediate to 72 h after hydrogen peroxide exposure. Over 90% of embolic symptoms occurred within 10 h of ingestion. Hyperbaric oxygen therapy: A total of 54/126 cases received hyperbaric oxygen therapy. Of those 54 cases, 31 had primary portal venous gas while the remaining 23 had air-gas emboli. Of the 23 air-gas emboli cases treated with hyperbaric oxygen therapy, 13 made full recoveries while 10 had residual symptoms or died. Mean time from air-gas emboli symptom onset to hyperbaric oxygen therapy in the full recovery group was 9 h compared to 18.2 h in the partial recovery/death group. Portal venous gas: There were 63 total reported cases of portal venous gas. Forty-nine of these cases were primary portal venous gas, 13 were secondary findings in patients with air-gas emboli and one case was secondary to non-air-gas emboli symptoms. Twenty-seven of 49 patients with portal venous gas (55%) as the primary finding had gastrointestinal bleeding. Thirty of the 63 cases received hyperbaric oxygen therapy for portal venous gas without any documented air-gas emboli. Deaths: Seventeen deaths occurred in the combined cohort. Of these, 13 were associated with high-concentration exposures. All deaths with reported time to symptom onset had symptoms within 1 h of exposure. CONCLUSION: This review of hydrogen peroxide exposure cases suggests that clinically significant embolic phenomena occur within 10 h of exposure, although delayed air-gas emboli do happen and should considered when deciding duration of observation. It remains equivocal whether hyperbaric oxygen therapy is beneficial in cases of primary portal venous gas without systemic involvement.

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.

Building First-Year Medical Students' Skills in Finding, Evaluating, and Visualizing Health Information Through a "Debunking Medical Myths" Curricular Module.

To provide an online service learning opportunity for medical students during the COVID-19 pandemic, medical faculty and librarians developed and implemented a "Debunking Medical Myths" module in which students learned to search for emerging medical literature, evaluate evidence, and use that evidence to create an infographics debunking a COVID-19-related myth for a non-medical audience. The resultant infographics are visually appealing and designed to make complex health information easy to understand. The module was well-received by students, who demonstrated a nuanced understanding of the use of infographics to convey health information, and students' work was evaluated highly by community members. Supplementary Information: The online version contains supplementary material available at 10.1007/s40670-022-01541-w.

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.

Updating the landmark literature for the practice of geriatrics: Notable articles from 2012-2019.

BACKGROUND: Remaining current on the latest advances in the peer-reviewed literature is a basic tenant of medical education and evidence-based practice. We updated an important prior publication (Vaughan, et al.) identifying landmark articles in geriatric medicine by considering the influence of altmetrics and updating the list with notable articles published between 2012 and 2019. METHODS: Articles were identified by searching Web of Science and Scopus for highly cited articles clinically relevant to geriatrics or gerontology and by searching the Altmetric Explorer database for relevant articles with high altmetric scores. The results of the literature search were screened and evaluated using a bibliometric score consisting of an adjusted journal impact factor, citation count, and altmetric score. RESULTS: The top 12 notable articles in geriatrics were selected by a consensus panel and ranked using an expert opinion survey. This process reinforces the concept of combining subjective and objective measures to identify notable articles to be used for the education of healthcare professionals in geriatrics principles of care for older adults. CONCLUSIONS: While our update was performed approximately 9 years after the initial identification of landmark articles, we propose that future updates are conducted at an interval of every 5 years by the governance of a national professional society.

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.

Air quality monitoring and measurement in an urban airshed: Contextualizing datasets from the Detroit Michigan area from 1952 to 2020.

With urban air quality being a pressing public health concern, community members are becoming increasingly engaged in determining the links between air quality and human health. Although new measurement tools such as low-cost sensors make local data more accessible, a better understanding of gaps in regional datasets is needed to develop effective metropolitan-scale solutions. Using scoping review methodology, we compiled 214 published journal articles and grey literature reports of air quality data from the Detroit, Michigan area from 1952 through 2020. This critical scoping review focuses on air quality datasets, but related topics such as health studies and community-based participatory science studies were examined from the included articles. Most of these publications were peer-reviewed journal articles published after 2001. Particulate matter, nitrous oxides, and sulfur dioxide were the most commonly studied air pollutants, and asthma was the most frequently associated health outcome paired with air pollution datasets. Few publications reported methods for community-based participatory science. This critical scoping review establishes a foundation of historical air quality data for the Detroit metropolitan area and a set of evaluation criteria that can be replicated in other urban centers. This foundation enables future detailed analysis of air quality datasets and showcases strategies for implementing effective community science programs and monitoring efforts.
