Using the Disruptive Score to Identify Publications That Changed Plastic Surgery Practice.

PURPOSE: The impact of academic publications is often characterized by the total number of future citations. However, this metric does not adequately characterize the true impact in terms of changing practices or paradigms. A new metric called the "disruption score" (DS) has been developed and validated in nonsurgical publications. This study aims to use the DS to identify the most disruptive publications in plastic surgery.The DS, a ratio of 2 numbers, varies between -1 and +1. Scores closer to -1 are developing papers that summarize the known literature while papers closer to +1 are disruptive-they result in a paradigm shift in the field of study. METHODS: A search was performed for all articles from 1954 to 2014 in the following journals: Plastic and Reconstructive Surgery; Aesthetic Surgery Journal; Journal of Plastic, Reconstructive, and Aesthetic Surgery; Annals of Plastic Surgery; Aesthetic Plastic Surgery; Clinics in Plastic Surgery; and Plastic Surgery. The disruptive score was calculated for each article.The top 100 papers ranked by DS were examined and any editorials/viewpoints, publications with less than 26 citations, or less than 3 references were excluded because of their subjective nature and smaller academic contribution. The remaining 64 publications were analyzed for topic, study type, and citation count. RESULTS: A total of 32,622 articles were found with a DS range from 0.385 to 0.923. The mean score of the top 64 articles was 0.539 with an average citation count of 195 and 9 references. Plastic and Reconstructive Surgery had the most disruptive papers with 50. There were no randomized controlled trials with a majority of the studies being technical descriptions or case series. CONCLUSIONS: There are many ways to measure academic success, but there are fewer ways to measure the impact of academic contributions. The DS is a novel measurement that can demonstrate when an article results in a paradigm shift as opposed to just total citation count. When applied to the plastic surgery literature, the DS demonstrates that technical innovation and creativity are the most academically impactful. Future evaluations of academic success should include the DS to measure the quality of academic contributions.

Systematic Review of Prevalence, Risk Factors, and Risk for Metachronous Advanced Neoplasia in Patients With Young-Onset Colorectal Adenoma.

BACKGROUND & AIMS: The incidence and mortality of early-onset colorectal cancer (CRC) are increasing. Adenoma detection, removal, and subsequent endoscopic surveillance might modify risk of CRC diagnosed before age 50 years (early-onset CRC). We conducted a systematic review of young-onset adenoma (YOA) prevalence, associated risk factors, and rate of metachronous advanced neoplasia after YOA diagnosis. METHODS: We performed a systematic search of multiple electronic databases through February 12, 2019 and identified studies of individuals 18 to 49 years old that reported prevalence of adenoma, risk factors for adenoma, and/or risk for metachronous advanced neoplasia. Summary estimates were derived using random effects meta-analysis, when feasible. RESULTS: The pooled overall prevalence of YOA was 9.0% (95% CI, 7.1%-11.4%), based on 24 studies comprising 23,142 individuals. On subgroup analysis, the pooled prevalence of YOA from autopsy studies was 3.9% (95% CI, 1.9%-7.6%), whereas the prevalence from colonoscopy studies was 10.7% (95% CI, 8.5%-13.5). Only advancing age was identified as a consistent risk factor for YOA, based on 4 studies comprising 78,880 individuals. Pooled rate of metachronous advanced neoplasia after baseline YOA diagnosis was 6.0% (95% CI, 4.1%-8.6%), based on 3 studies comprising 1493 individuals undergoing follow-up colonoscopy, with only 1 CRC case reported. Overall, few studies reported metachronous advanced neoplasia and no studies evaluated whether routine surveillance colonoscopy decreases risk of CRC. CONCLUSIONS: In a systematic review, we estimated the prevalence of YOA to be 9% and to increase with age. Risk for metachronous advanced neoplasia after YOA diagnosis is estimated to be 6%. More research is needed to understand the prevalence, risk factors, and risk of CRC associated with YOA.

Pooled 3-Anatomic-Site Testing for Chlamydia trachomatis and Neisseria gonorrhoeae: A Systematic Review and Meta-Analysis.

BACKGROUND: Pooled testing for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) may be a cost-saving solution to increase screening by simplifying testing procedures and reducing resource burdens. We conducted a systematic review and meta-analysis to examine the performance of pooled 3-anatomic-site testing (pharyngeal, rectal, and urogenital sites) for CT and NG in comparison with single-anatomic-site testing. METHODS: We conducted a systematic literature search in PubMed, Embase, and Web of Science to identify original evaluation studies of the performance of pooled testing for CT and NG infections and identified 14 studies for inclusion. Each study was systematically evaluated for bias. We conducted bivariate fixed-effects and random-effects meta-analyses using a full Bayesian method of the positive percent agreement and negative percent agreement. RESULTS: The combined positive percent agreement for CT was 93.11% (95% confidence interval [CI], 91.51%-94.55%), and the negative percent agreement was 99.44% (95% CI, 99.18%-99.65%). For NG, the combined positive percent agreement was 93.80% (95% CI, 90.26%-96.61%), and the negative percent agreement was 99.73% (95% CI, 99.30%-99.97%). CONCLUSIONS: We found that pooled 3-anatomic-site tests performed similarly to single-anatomic-site tests for the detection of CT and NG. The pooled 3-anatomic-site tests have the added potential benefit of reduced cost and resource requirement, which could lead to improved testing access and screening uptake.

Mailed Outreach Is Superior to Usual Care Alone for Colorectal Cancer Screening in the USA: A Systematic Review and Meta-analysis.

Mailed outreach promoting colorectal cancer (CRC) screening with a stool blood test kit may increase participation, but magnitude and consistency of benefit of this intervention strategy is uncertain. Our aim was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing mailed outreach offering stool tests to usual care, clinic-based screening offers on CRC screening uptake in the USA. We performed a systematic literature search of five databases for RCTs of mailed outreach from January 1980 through June 2017. Primary outcome was screening completion, summarized using random-effects meta-analysis as pooled differences in proportion completing the screening and relative risk of achieving screening compared to control. Subgroup analyses by test type offered-fecal immunochemical test (FIT) or guaiac fecal occult blood test (gFOBT), the presence of telephone reminders, and the presence of predominant underserved/minority population within study were performed. Quality of evidence was evaluated using the GRADE framework. Seven RCTs which enrolled 12,501 subjects were included (n = 5703 assigned mailed outreach and n = 6798 usual care). Mailed outreach resulted in a 28% absolute (95% CI 25-30%; I2 = 47%) and a 2.8-fold relative (RR 2.65, 95% CI 2.03-3.45; I2 = 92%) increase in screening completion compared to usual care, with a number needed to invite estimated to be 3.6. Similar outcomes were observed across subgroups. Overall body of evidence was at moderate quality. Mailed outreach offering a gFOBT or FIT is associated with a large and consistent increase in CRC screening completion and should be considered for more widespread implementation for improving screening rates nationwide.

A Bibliometric Analysis of Clinical and Translational Research in Pediatric Gastroenterology From 1970 to 2017.

OBJECTIVES: Pediatric gastroenterology is a clinical and research discipline principally developed over the past 50 years. Bibliometric methods provide quantitative analysis and identify research trends. Study aims were to characterize the growth and trends in pediatric gastroenterology clinical and translational research using citation analysis. METHODS: Using citations analysis software, a search strategy specific for pediatric gastroenterology was implemented for the years 1970 to 2017. The 50 most-cited research articles per decade were identified. These 250 articles were coded for topic and study attribute. Analysis included authors, affiliations, journals, countries, and funding sources. RESULTS: Overall average annual growth rate for pediatric gastroenterology publications was significantly higher than that for general pediatrics (51.7% vs 6.2%; P < 0.05). Among the top 250 cited articles, the distribution of study focus was epidemiology (43%), pathophysiology (18%), treatment (16%), diagnosis (8%), prevention (8%), and comorbidities of gastrointestinal diseases (7%).There were 38 different topics represented and there was a notable shift in topic focus over time. Cholestasis, biliary atresia, and total parenteral nutrition were common topics from 1970 to 1989 and obesity, nonalcoholic fatty liver disease, and eosinophilic esophagitis were common topics after 1990. Notably, 2.3% of the authors accounted for 30% of the top 250 articles. CONCLUSIONS: Pediatric gastroenterology research has undergone rapid growth yielding advancements in the management of gastrointestinal conditions in children. The emergence of new diseases in need of better diagnostics and therapeutics led to a temporal shift in research focus. Further advancements will require multidisciplinary collaborations and continued funding for pediatric gastroenterology research.

The Role of Health Literacy in Skin Cancer Preventative Behavior and Implications for Intervention: A Systematic Review.

BACKGROUND: Health literacy is essential for individuals to access, understand, and utilize information and services to inform health related decisions and actions. As one of the most diagnosed and preventable forms of cancer, skin cancer disease risk can be reduced through preventative behavior. Currently, there is no focused study looking specifically at health literacy and skin cancer. An understanding of how health literacy affects skin cancer-related preventive behaviors can improve current practices in skin cancer prevention. OBJECTIVE: To systematically identify, synthesize, and summarize findings on the role of health literacy in skin cancers (including cutaneous squamous cell carcinoma, basal cell carcinoma, and melanoma), with a focus on preventive behaviors using studies that utilized quantifiable health literacy measurements. METHODS: A literature search was performed by searching PubMed, Embase, PsycINFO, and CINAHL from inception until September 26, 2023 to identify cross-sectional, case-control, cohort, or randomized controlled studies that investigated the association between health literacy and skin cancer prevention and diagnosis. RESULTS: Health literacy levels varied across geographic regions, specific populations, and ethnicities. Most of the included studies found a positive association between higher health literacy and better skin cancer preventative behaviors. This included sun-protective behaviors such as: wearing sleeved shirts or shirts with collars, using gloves, covering head and face, limiting sun exposure, more sunscreen use, and less sunbathing or indoor tanning. Higher health literacy was associated with increased likelihood to engage in genetic testing and less family influence on health in one study which assessed determinants of interest in skin cancer genetic testing. Another study investigating family communication about skin cancer found that higher health literacy was associated with increased family communication regarding general cancer risk. One sun protection interventional education program was effective at increasing participants' knowledge, awareness of skin cancer risk, willingness to change sun protection, and use of sun protection, but results varied between ethnic groups. CONCLUSIONS: Skin cancer-related educational interventions can be effective in improving health literacy and potentially lessen the impact of skin cancer through positive behavior modification, early detection, and disease knowledge and awareness. Interventions need to be tailored to its target population to maximize effectiveness due to the varying baseline of health literacy identified across different geographic and ethnic groups.

Red Flag Signs and Symptoms for Patients With Early-Onset Colorectal Cancer: A Systematic Review and Meta-Analysis.

Importance: Early-onset colorectal cancer (EOCRC), defined as a diagnosis at younger than age 50 years, is increasing, and so-called red flag signs and symptoms among these individuals are often missed, leading to diagnostic delays. Improved recognition of presenting signs and symptoms associated with EOCRC could facilitate more timely diagnosis and impact clinical outcomes. Objective: To report the frequency of presenting red flag signs and symptoms among individuals with EOCRC, to examine their association with EOCRC risk, and to measure variation in time to diagnosis from sign or symptom presentation. Data Sources: PubMed/MEDLINE, Embase, CINAHL, and Web of Science were searched from database inception through May 2023. Study Selection: Studies that reported on sign and symptom presentation or time from sign and symptom presentation to diagnosis for patients younger than age 50 years diagnosed with nonhereditary CRC were included. Data Extraction and Synthesis: Data extraction and quality assessment were performed independently in duplicate for all included studies using Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guidelines. Joanna Briggs Institute Critical Appraisal tools were used to measure risk of bias. Data on frequency of signs and symptoms were pooled using a random-effects model. Main Outcomes and Measures: Outcomes of interest were pooled proportions of signs and symptoms in patients with EOCRC, estimates for association of signs and symptoms with EOCRC risk, and time from sign or symptom presentation to EOCRC diagnosis. Results: Of the 12 859 unique articles initially retrieved, 81 studies with 24 908 126 patients younger than 50 years were included. The most common presenting signs and symptoms, reported by 78 included studies, were hematochezia (pooled prevalence, 45% [95% CI, 40%-50%]), abdominal pain (pooled prevalence, 40% [95% CI, 35%-45%]), and altered bowel habits (pooled prevalence, 27% [95% CI, 22%-33%]). Hematochezia (estimate range, 5.2-54.0), abdominal pain (estimate range, 1.3-6.0), and anemia (estimate range, 2.1-10.8) were associated with higher EOCRC likelihood. Time from signs and symptoms presentation to EOCRC diagnosis was a mean (range) of 6.4 (1.8-13.7) months (23 studies) and a median (range) of 4 (2.0-8.7) months (16 studies). Conclusions and Relevance: In this systematic review and meta-analysis of patients with EOCRC, nearly half of individuals presented with hematochezia and abdominal pain and one-quarter with altered bowel habits. Hematochezia was associated with at least 5-fold increased EOCRC risk. Delays in diagnosis of 4 to 6 months were common. These findings highlight the need to identify concerning EOCRC signs and symptoms and complete timely diagnostic workup, particularly for individuals without an alternative diagnosis or sign or symptom resolution.

Current practices in library/informatics instruction in academic libraries serving medical schools in the Western United States: a three-phase action research study.

BACKGROUND: To conduct a systematic assessment of library and informatics training at accredited Western U.S. medical schools. To provide a structured description of core practices, detect trends through comparisons across institutions, and to identify innovative training approaches at the medical schools. METHODS: Action research study pursued through three phases. The first phase used inductive analysis on reported library and informatics skills training via publicly-facing websites at accredited medical schools and the academic health sciences libraries serving those medical schools. Phase Two consisted of a survey of the librarians who provide this training to undergraduate medical education students at the Western U.S. medical schools. The survey revealed gaps in forming a complete picture of current practices, thereby generating additional questions that were answered through the Phase Three in-depth interviews. RESULTS: Publicly-facing websites reviewed in Phase One offered uneven information about library and informatics training at Western U.S. medical schools. The Phase Two survey resulted in a 77% response rate. The survey produced a clearer picture of current practices of library and informatics training. The survey also determined the readiness of medical students to pass certain aspects of the United States Medical Licensure Exam. Most librarians interacted with medical school curricular leaders through either curricula committees or through individual contacts. Librarians averaged three (3) interventions for training within the four-year curricula with greatest emphasis upon the first and third years. Library/informatics training was integrated fully into the respective curricula in almost all cases. Most training involved active learning approaches, specifically within Problem-Based Learning or Evidence-Based Medicine contexts. The Phase Three interviews revealed that librarians are engaged with the medical schools' curricular leaders, they are respected for their knowledge and teaching skills, and that they need to continually adapt to changes in curricula. CONCLUSIONS: This study offers a long overdue, systematic view of current practices of library/informatics training at Western U.S. medical schools. Medical educators, particularly curricular leaders, will find opportunities in this study's results for more productive collaborations with the librarians responsible for library and informatics training at their medical schools.

Unit costs of needle and syringe program provision: a global systematic review and cost extrapolation.

BACKGROUND: Needle and syringe programs (NSPs) are effective at preventing HIV and hepatitis C virus (HCV) among people who inject drugs (PWID), yet global coverage is low, partly because governments lack data on the cost and cost-effectiveness of NSP in their countries to plan and fund their responses. We conducted a global systematic review of unit costs of NSP provision to inform estimation of cost drivers and extrapolated costs to other countries. METHODS: We conducted a systematic review to extract data on the cost per syringe distributed and its cost drivers. We estimated the impact of country-level and program-level variables on the cost per syringe distributed using linear mixed-effects models. These models were used to predict unit costs of NSP provision, with the best performing model used to extrapolate the cost per syringe distributed for 137 countries. The total cost for a comprehensive NSP (200 syringes per PWID/year) was also estimated for 68 countries with PWID population size estimates. RESULTS: We identified 55 estimates of the unit cost per syringe distributed from 14 countries. Unit costs were extrapolated for 137 countries, ranging from $0.08 to $20.77 (2020 USD) per syringe distributed. The total estimated spend for a high-coverage, comprehensive NSP across 68 countries with PWID size estimates is $5 035 902 000 for 10 887 500 PWID, 2.1-times higher than current spend. CONCLUSION: Our review identified cost estimates from high-income, upper-middle-income, and lower-middle-income countries. Regression models may be useful for estimating NSP costs in countries without data to inform HIV/HCV prevention programming and policy.

The impact of a medical improv curriculum on wellbeing and professional development among pre-clinical medical students.

Medical students experience rising rates of burnout throughout their training. Efforts have been made to not only mitigate its negative effects, but also prevent its development. Medical improv takes the basic ideas of improvisational theatre and applies them to clinical situations. Given improv's focus on self-awareness and reflection, in addition to its spontaneous nature, we hypothesized it had the potential to serve as a creative outlet, a way to prevent and/or mitigate the negative effects of stress, burnout, and fatigue, and provide a learning environment to develop skills necessary to succeed as a physician. University of California (UC) San Diego School of Medicine developed a medical improv elective for pre-clinical students and assessed its effects on student development and wellbeing. Students enrolled in the elective between Fall 2019 and Fall 2020 at UC San Diego School of Medicine were surveyed pre- and post- course completion using both qualitative and quantitative methods. Students noted significant improvement in domains related to proactivity in their professional career (3.15 to 4.00, p = 0.02), wellbeing (3.0 to 4.4, p < 0.001), engagement with their studies (3.85 to 4.52, p = 0.02), and communication (3.75 to 4.3, p = 0.04) after completion of the medical improv elective. We describe a pilot-study demonstrating the positive effects of improv on medical student wellbeing and professional development, laying the groundwork for both future study of improv on student wellness and its implementation in the pre-clinical curriculum.

Searching the literature using medical subject headings versus text word with PubMed.

OBJECTIVE/HYPOTHESIS: This study was conducted to investigate the performance of two search strategies in the retrieval of information from the National Library of Medicine (NLM) on otolaryngology-head and neck surgery related conditions and diagnoses using PubMed. METHODS: Two search strategies-one based on the use of Medical Subject Headings (MeSH) and the second based on text word searching-were compared. RESULTS: The MeSH search provided a more efficient search than the text word search. CONCLUSIONS: Head and neck surgeons can most efficiently search the NLM using PubMed as a search engine by initiating the search with MeSH terms. Once a key article is identified, the searcher should use the "Related Articles" feature.
