Dr. Google vs. Dr. ChatGPT: Exploring the Use of Artificial Intelligence in Ophthalmology by Comparing the Accuracy, Safety, and Readability of Responses to Frequently Asked Patient Questions Regarding Cataracts and Cataract Surgery. Semin Ophthalmol 2024:1-8. [PMID: 38516983 DOI: 10.1080/08820538.2024.2326058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 02/27/2024] [Indexed: 03/23/2024]
Abstract
PURPOSE Patients are using online search modalities to learn about their eye health. While Google remains the most popular search engine, the use of large language models (LLMs) like ChatGPT has increased. Cataract surgery is the most common surgical procedure in the US, and there is limited data on the quality of online information that populates after searches related to cataract surgery on search engines such as Google and LLM platforms such as ChatGPT. We identified the most common patient frequently asked questions (FAQs) about cataracts and cataract surgery and evaluated the accuracy, safety, and readability of the answers to these questions provided by both Google and ChatGPT. We demonstrated the utility of ChatGPT in writing notes and creating patient education materials. METHODS The top 20 FAQs related to cataracts and cataract surgery were recorded from Google. Responses to the questions provided by Google and ChatGPT were evaluated by a panel of ophthalmologists for accuracy and safety. Evaluators were also asked to distinguish between Google and LLM chatbot answers. Five validated readability indices were used to assess the readability of responses. ChatGPT was instructed to generate operative notes, post-operative instructions, and customizable patient education materials according to specific readability criteria. RESULTS Responses to 20 patient FAQs generated by ChatGPT were significantly longer and written at a higher reading level than responses provided by Google (p < .001), with an average grade level of 14.8 (college level). Expert reviewers were correctly able to distinguish between a human-reviewed and chatbot generated response an average of 31% of the time. Google answers contained incorrect or inappropriate material 27% of the time, compared with 6% of LLM generated answers (p < .001). When expert reviewers were asked to compare the responses directly, chatbot responses were favored (66%). CONCLUSIONS When comparing the responses to patients' cataract FAQs provided by ChatGPT and Google, practicing ophthalmologists overwhelming preferred ChatGPT responses. LLM chatbot responses were less likely to contain inaccurate information. ChatGPT represents a viable information source for eye health for patients with higher health literacy. ChatGPT may also be used by ophthalmologists to create customizable patient education materials for patients with varying health literacy.

Abstract
PURPOSE/OBJECTIVE(S) Anal cancer disproportionately affects PWH despite antiretroviral therapy. Data on CRT outcomes are limited. Modern IMRT CRT decreases acute toxicity but may exacerbate immune dysregulation from chronic HIV. Although historical CRT has been associated with prolonged CD4 count suppression, little is known about late immunotoxicity in PWH after contemporary CRT. We report clinical outcomes and long term immunotoxicity. MATERIALS/METHODS Single-center retrospective review of all PWH confirmed on chart review with anal squamous cell carcinoma without prior pelvic irradiation treated with definitive IMRT CRT. Patient and CRT factors including HIV suppression (<200 copies/mL), mean CD4 count (cells/µL), and receipt of capecitabine (C) or 5-fluorouracil (F) +/- mitomycin (M) were summarized with n (%) or median (interquartile range). Progression-free and overall survival (PFS; OS) were estimated per Kaplan-Meier with 95% confidence intervals and compared with log-rank tests. Mean CD4 count and CD4:CD8 were compared by HIV suppression status (Welch's t-test); longitudinal changes in median CD4 count and CD4:CD8 were compared between baseline vs. nadir (within 6 months of CRT start) and 1-year follow-up for patients with complete data (Wilcoxon signed-rank test). RESULTS A total of 23 PWH were treated between 2010-2022, median age 52, median 16 (13 - 19) years after HIV diagnosis; 4 had unsuppressed HIV; AJCC 8th stage I/II/III/IV 5/5/12/1. Radiation dose was median 54 Gy in 30 fractions over 42 (40 - 44) days. Most had C+M (57%); only 43% had 2×M with either C or F. One had neoadjuvant carboplatin/paclitaxel/pembrolizumab. With 2.9 (1.03 - 3.3) years follow-up, median OS was 6.6 (6.2 - unreached [UR]) years. With 2.2 (0.67 - 2.7) years follow-up, median PFS was UR. OS and PFS were similar regardless of HIV suppression status (both P ≥ 0.09). Overall baseline CD4 count was 458 (226 - 484), and CD4:CD8 was 0.54 (0.2 - 0.7). Nadir CD4 was 100 (59 - 126) and CD4:CD8 was 0.3 (0.2 - 0.4). Baseline and nadir CD4 count and CD4:CD8 were lower if HIV-unsuppressed (each P ≤ 0.04). One year after CRT, CD4 count was 252 (102 - 276), while CD4:CD8 was 0.5 (0.2 - 0.7). For 7 patients with repeated values the change in median from baseline to nadir, 6-, and 12-months post-CRT was -282, -549 (both P = 0.02), -480 (P = 0.9) for CD4 counts, and -0.7, -0.5, -0.4 (each P > 0.5) for CD4:CD8 ratios; none had unsuppressed HIV. CONCLUSION Definitive IMRT CRT with guideline-concordant doublet chemotherapy for anal cancer in PWH is effective despite unsuppressed HIV. Treatment leads to prolonged immunological changes that may increase the risk of HIV-related morbidity and mortality. Modifiable treatment-related causes of hematoimmunologic toxicity should be investigated further, and immune surveillance after CRT should be considered to better understand impact on quality of life.

The use of Google Trends and Twitter data as a tool for evaluating public interest in hyaluronic acid eyelid filler. J Clin Transl Res 2023; 9:76-83. [PMID: 37034000 PMCID: PMC10075089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 01/04/2023] [Accepted: 01/12/2023] [Indexed: 04/11/2023] Open
Abstract
Background Google Trends and the Twitter Academic Research Product Tract (TARPT) are free, online tools that can be used to evaluate public interest in plastic surgery procedures. Aim The aim of the study was to evaluate the correlation between online public interest in hyaluronic acid eyelid filler on two popular web platforms (Google and Twitter) and hyaluronic acid filler procedure volumes in the United States. Methods The Google Trends database and the TARPT tool were used to calculate the number of annual Google searches and Twitter tweets, respectively, related to 10 search terms associated with hyaluronic acid eyelid filler injections from January 2010 to December 2020. Annual procedure volumes for hyaluronic acid filler injections were obtained from the American Society of Plastic Surgery (ASPS). Univariate linear regression was used to correlate Google searches to ASPS procedure volumes and Twitter tweet volumes to ASPS procedure volumes. Results Significant positive correlations were found between Google Trends data and ASPS procedure volumes for 8/10 search terms and between Twitter tweet volumes and ASPS procedure volumes for 6/10 search terms, respectively. Online public interest in eyelid filler related search terms increased significantly over time according to an exponential model (P < 0.0001). Conclusions We observed statistically significant positive associations between public interest related to eyelid filler on two online platforms, Google and Twitter, and hyaluronic acid soft-tissue filler procedure volumes. The Google Trends and TARPT databases represent free information sources for surgeons that may be used to inform marketing and advertising decisions and to anticipate patient inquiries during the patient encounter. Relevance for Patients Information provided by the Google Trends and TARPT tools can be used by surgeons to (1) inform marketing and advertising strategies and (2) gain insight into which procedures patients are researching during a given time period, preparing them to best address the evolving needs of patients.

Abstract
BACKGROUND Abnormal scaphoid alignment after fracture is used as an indication for fixation. Acceptable alignment after reduction and fixation of scaphoid fractures is not well defined. We systematically reviewed the literature to identify how scaphoid malunion is currently defined and by what parameters. METHODS A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Multiple databases were searched for studies published in the English language that reported on outcomes after scaphoid malunion and included measurements to define malunions. Radiographic scaphoid measurement parameters were collected. Clinical outcome measures recorded included grip strength, wrist range of motion, and patient-reported outcome measures. Study quality was analyzed using the Methodological Index for Non-Randomized Studies (MINORS) criteria. Descriptive summaries of the studies are presented. RESULTS The initial search yielded 1600 articles. Ten articles (161 participants, 93% males, mean age = 28.3 + 6.3 years, mean MINORS score = 10.2 + 1.6) were included and analyzed. Scaphoid malunion was defined if the lateral intrascaphoid angle (LISA) was >45° (3 articles), LISA >35° (1 article), and height to length ratio >0.6 (3 articles). Four out of 5 studies found no significant associations between patient outcomes and degree of scaphoid malunion measured on imaging. CONCLUSIONS There is a lack of consensus for defining scaphoid malunion on imaging and absence of correlation between findings on imaging and patient outcomes. Future studies defining scaphoid malunion should be appropriately powered, incorporate measures of intrarater and interrater reliabilities for all reported imaging measurements, and utilize validated patient-reported outcome measures to reflect that malunion is associated with inferior outcomes meaningful to patients.

Analysis of the Readability and Accountability of Online Patient Education Materials Related to Glaucoma Diagnosis and Treatment. Clin Ophthalmol 2023; 17:779-788. [PMID: 36923248 PMCID: PMC10008728 DOI: 10.2147/opth.s401492] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 02/15/2023] [Indexed: 03/10/2023] Open
Abstract
Purpose To assess the readability and accountability of online patient education materials related to glaucoma diagnosis and treatment. Methods We conducted a Google search for 10 search terms related to glaucoma diagnosis and 10 search terms related to glaucoma treatment. For each search term, the first 10 patient education websites populated after Google search were assessed for readability and accountability. Readability was assessed using five validated measures: Flesch Reading Ease (FRE), Gunning Fog Index (GFI), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and New Dale-Chall (NDC). Accountability was assessed using the Journal of the American Medical Association (JAMA) benchmarks. The source of information for each article analyzed was recorded. Results Of the 200 total websites analyzed, only 11% were written at or below the recommended 6th grade reading level. The average FRE and grade level for 100 glaucoma diagnosis-related articles were 42.02 ± 1.08 and 10.53 ± 1.30, respectively. The average FRE and grade level for 100 glaucoma treatment-related articles were 43.86 ± 1.01 and 11.29 ± 1.54, respectively. Crowdsourced articles were written at the highest average grade level (12.32 ± 0.78), followed by articles written by private practice/independent users (11.22 ± 1.74), national organizations (10.92 ± 1.24), and educational institutions (10.33 ± 1.35). Websites averaged 1.12 ± 1.15 of 4 JAMA accountability metrics. Conclusion Despite wide variation in the readability and accountability of online patient education materials related to glaucoma diagnosis and treatment, patient education materials are consistently written at levels above the recommended reading level and often lack accountability. Articles from educational institutions and national organizations were often written at lower reading levels but are less frequently encountered after Google search. There is a need for accurate and understandable online information that glaucoma patients can use to inform decisions about their eye health.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection in the world, with the ability to cause external genital warts and cancers. The HPV vaccine, first released in the United States of America (USA) in 2006, has been shown to protect against the highest risk HPV strains responsible for the majority of HPV-related cancers. In mainland China, the HPV vaccine was only recently approved in 2016 and is therefore not readily available. As a result, Chinese international students (CIS) studying in the USA continue to have low HPV vaccination rates. This study completed in person and online surveying of 396 CIS at a large Southern California university, with the goal of better understanding CIS knowledge and awareness of HPV disease, vaccination and healthcare behaviors, and sexual activity. Among participants, the reported HPV vaccination rate was 61% (females: 85%; males: 32%). HPV vaccination was significantly correlated with a past visit to the on-campus student health center, having university-sponsored student health insurance, higher self-perceived HPV knowledge, and increased willingness to pay for vaccination. A large portion of participants portrayed low levels of sexual activity, which suggests that CIS can take advantage of catch-up HPV vaccination recommendations through 26 years of age. The results of this study can be used to inform policy initiatives, particularly at the campus level, that attempt to improve HPV vaccination rates amongst CIS.

Abstract
PURPOSE To assess the readability and accountability of online patient education materials related to oculoplastic diagnoses and treatments, and to determine the source of information encountered by patients searches. METHODS We conducted a Google search for 20 search terms related to common oculoplastic diagnoses and treatments and analyzed the first 10 patient education websites populated for each term. Readability was assessed using four validated measures: Gunning Fog Index, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, and New Dale-Chall Readability. Accountability was assessed using 4 JAMA benchmarks on a scale of 0-4, with one point awarded for each of the following accountability criteria provided on the website: (1) including all authors and their relevant credentials (2) listing references (3) providing disclosures and (4) providing date of last update. RESULTS The average grade level of 200 websites analyzed was 10.89, with 29% written at less than the 6th grade reading level recommended by the American Medical Association. The source of online information was most frequently educational institutions (36%) and private practices (34%), with fewer online patient education materials from national organizations (18%) and crowdsourced websites (12%). There were no significant differences in readability when comparing searches related to oculoplastics diagnoses versus treatments. Websites averaged 0.91 out of a maximum of 4 recommended accountability criteria, reflecting low overall accountability. CONCLUSIONS Online education resources encountered by patients are often written at inappropriate reading levels and demonstrate low accountability. Online patient education materials are most frequently maintained by educational institutions and private practices, with fewer articles from national organizations. Revision of online materials may be necessary to improve health literacy among oculoplastic patients.

#CosmeticsTwitter: Predicting Public Interest in Nonsurgical Cosmetic Procedures Using Twitter Data. Aesthet Surg J 2022; 42:NP788-NP797. [PMID: 35675468 DOI: 10.1093/asj/sjac147] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND The utilization of social media in plastic surgery is expanding. The Twitter Academic Research Product Tract (TARPT) database provides plastic surgeons the opportunity to monitor public interest in plastic surgery procedures. Previously, TARPT was shown to be effective in tracking public interest in surgical cosmetic facial and body procedures. OBJECTIVES The authors sought to determine the ability of the TARPT tool to track and predict public interest in nonsurgical cosmetic procedures and to examine temporal public interest trends in nonsurgical cosmetic procedures. METHODS The authors employed the TARPT tool to calculate the total number of tweets containing keywords related to 15 nonsurgical cosmetic procedures from 2010 to 2020. Annual case volumes were obtained for each of the 15 procedures from annual reports provided by the American Society of Plastic Surgeons. Univariate linear regression was employed to compare tweet volumes and procedure volumes, with P < 0.05 as a threshold for significance. RESULTS Univariate linear regression revealed significant positive correlations between tweet volumes and American Society of Plastic Surgeons procedure volumes for 10 search terms representing 6 nonsurgical cosmetic procedures: "xeomin," "microdermabrasion," "facial filler," "fat filler," "fat injections," "fat transfer," "hyaluronic acid filler," "hyaluronic acid injection," "HA filler," and "PRP filler." Thirty-two search terms did not demonstrate a significant relationship. CONCLUSIONS The TARPT tool is an informative data source for plastic surgeons with the potential to guide marketing and advertising strategies, and monitor public interest in nonsurgical cosmetic procedures, helping surgeons respond to patients' evolving needs.

Out-of-Pocket and Total Costs for Common Hand Procedures From 2008 to 2016: A Nationwide Claims Database Analysis. J Hand Surg Am 2022; 47:1057-1067. [PMID: 35985865 DOI: 10.1016/j.jhsa.2022.06.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 04/29/2022] [Accepted: 06/15/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE Rising patient out-of-pocket (OOP) costs and financial distress have been associated with reduced access to and delays in care. We evaluated whether OOP and total costs for common hand procedures have increased from 2008 to 2016 and identified key drivers of these costs. METHODS Using the IBM MarketScan Research Databases, we identified patients who underwent trigger finger release, open carpal tunnel release, thumb carpometacarpal joint arthroplasty, cubital tunnel release, or open treatment of distal radius fracture in the outpatient setting between 2008 and 2016. Patient OOP costs included copayment, coinsurance, and deductible payments. Costs not directly related to medical care, such as transportation and childcare costs, were not included. The overall cost was defined as the sum of the patient OOP cost and insurer reimbursements. We calculated changes in OOP and total overall costs over the study period. We also performed multivariable linear regressions to evaluate the associations between costs and procedure type, insurance type, region, and site of service. RESULTS The mean patient OOP cost increased by 55% to 71% and the total overall cost increased by 20% to 45%, depending on the procedure, between 2008 and 2016. Facility overall costs increased by 38%, whereas professional overall costs increased by 9%. Procedures performed in an office-based setting were associated with the lowest patient OOP and total overall costs, whereas high-deductible health plans were associated with the highest OOP costs. CONCLUSIONS Patient OOP and total overall costs increased for the most common hand procedures between 2008 and 2016, driven by a substantial increase in facility costs. Office-based procedures were associated with the lowest costs. CLINICAL RELEVANCE To alleviate the rising patient cost burden, hand surgeons could incorporate OOP cost considerations into shared decision-making tools, identify patients who may benefit from financial counseling, and shift procedures to an office-based setting.

Abstract
PURPOSE Risks of Ponte osteotomies (POs) used for posterior spinal fusion (PSF) for Adolescent Idiopathic Scoliosis (AIS) are challenging to assess because of the rarity of complications. Using a national administrative claims database, we evaluated trends, costs and complications associated with PO used in PSF for AIS patients. METHODS Using ICD-9/CPT codes, we identified patients (ages 10-18) with AIS who underwent PSF (± PO) between 2007 and 2015 in the IBM® MarketScan® Commercial Databases. Costs and trends of POs were evaluated. Odds of neurological complications and readmissions within 90 days and reoperations within 90 days and 2 years were assessed. RESULTS We identified 8881 AIS patients who had undergone PSF, of which 8193 had 90-day follow-up and 4248 had 2-year follow-up. Overall, 28.8% had PO. Annual rate of POs increased from 17.3 to 35.2% from 2007 to 2015 (p < 0.001). Risk-adjusted multivariable logistic regression demonstrated no relationship between POs and neurologic complications (p = 0.543). POs were associated with higher odds for readmission (1.52 [1.21-1.91]; p < 0.001) and reoperation (2.03 [1.13-3.59]; p = 0.015) within 90 days, but there were no differences in the odds of reoperation within 2 years (p = 0.836). Median hospital costs were $15,854 (17.4%) higher for patients with POs (p < 0.001) and multivariable modeling demonstrated POs to be an independent predictor of increased costs (p < 0.001). CONCLUSION Annual rate of POs increased steadily from 2007 to 2015. POs were not associated with increased odds of neurological complications but had higher costs and higher rates of readmissions and reoperations within 90 days. By 2 years, differences in reoperation rate were not significant. LEVEL OF EVIDENCE III.

Energizing charged particles by an orbit instability in a slowly rotating magnetic field. Phys Rev E 2022; 106:045209.

Abstract
The stability of charged particle motion in a uniform magnetic field with an added spatially uniform transverse rotating magnetic field (RMF) is studied analytically. It is found that the stability diagram of a single particle's orbit depends critically on the chosen boundary conditions. We show that for many boundary conditions and wide regions in the parameter space, RMFs oscillating far below the cyclotron frequency can cause linear instabilities in the motion which break μ invariance and energize particles. Such energization may appear at odds with the adiabatic invariance of μ; however, adiabatic invariance is an asymptotic result and does not preclude such heating by magnetic fields oscillating at slow frequencies. This mechanism may contribute to heating in the edge plasma of field-reversed configurations (FRCs) in rotamak-FRC experiments. Furthermore, these RMF-driven instabilities may significantly enhance azimuthal current drive during the formation of FRCs in such devices.

Analysis of Website Accessibility and Content for All 92 Accredited Hand Surgery Fellowship Programs in the United States: An Update. JOURNAL OF HAND SURGERY GLOBAL ONLINE 2022; 4:269-275. [PMID: 36157307 PMCID: PMC9492797 DOI: 10.1016/j.jhsg.2022.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 05/09/2022] [Indexed: 11/26/2022] Open
Abstract
Purpose The internet is an important information source for hand surgery fellowship applicants. A previous analysis of hand fellowship websites in 2014 demonstrated they were often inaccessible and incomplete. Given the increased importance of virtual information, we performed an updated assessment of the accessibility and content of hand fellowship program websites. Methods Websites of 92 accredited hand surgery fellowship programs were evaluated for the following: (1) accessibility; and (2) the presence of 13 fellow recruitment and 13 fellow education criteria, as defined in prior studies. We used Mann-Whitney U and Kruskal-Wallis tests to assess whether the geographic region, number of fellows, or affiliation with a top orthopedic hospital or medical school were associated with website content. Results Functional website links that redirect to the appropriate fellowship program website are provided for 47 (51.1%) of 92 programs on the American Society for Surgery of the Hand fellowship directory. All missing websites were accessible via independent Google searches. Fellowship program websites contained an average of 13.9 ± 4.4 total criteria (range, 3–23). Of the 15 criteria examined in both 2014 and 2021, there were significant (P < .05) increases in the prevalences of 4: current fellow(s), salary, social media links, and operative experience. Conclusions Despite a slight increase in accessibility since 2014, nearly half of hand surgery fellowship program websites remain inaccessible from the American Society for Surgery of the Hand directory. Program websites averaged approximately half of the criteria analyzed, with many websites failing to provide information deemed important by applicants. Clinical relevance Our study provides an impetus for improving the accessibility and content of hand surgery fellowship websites. A website that incorporates criteria examined in this study can serve as an effective recruitment tool by providing consistent baseline information that may help applicants decide which programs align with personal values and future career goals.

Use of a Mylar filter to eliminate vacuum ultraviolet pulse pileup in low-energy x-ray measurements. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2022; 93:093531.

Abstract
We describe a method to reduce vacuum ultraviolet (VUV) pulse pileup (PPU) in x-ray pulse-height Silicon Drift Detector (SDD) signals. An Amptek FAST SDD, with C1 (Si3N4) window, measures bremsstrahlung emitted from PFRC-2 plasma to extract the electron temperature (Te) and density (ne). The C1 window has low transmissivity for photons with energy below 200 eV though will transmit some VUV and soft x-ray photons, which PFRC-2 plasmas abundantly emit. Multi-VUV-photon PPU contaminates the interpretation of x rays with energy > 100 eV, particularly in a low-energy exponential tail. The predicted low transmissivity of ∼1 μm thick Mylar [polyethylene terephthalate (PET)] to photons of energy <100 eV led to the selection of Mylar as the candidate filter to reduce VUV PPU. Experiments were conducted on an x-ray tube with a graphite target and on a quasi-Maxwellian tenuous plasma (ne ∼ 109 cm-3) with effective temperatures reaching 1500 eV. A Mylar filter thickness of 850 nm is consistent with the results. The Mylar-filter-equipped SDD was then used on the PFRC-2 plasma, showing a substantial reduction in the low-energy x-ray signal, supporting our hypothesis of the importance of VUV PPU. We describe the modeling and experiments performed to characterize the effect of the Mylar filter on SDD measurements.

[PMID: 36092462 PMCID: PMC9451038 DOI: 10.2147/opth.s378795] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 08/15/2022] [Indexed: 11/23/2022] Open
Abstract
Aim To evaluate and quantify social media presence of ophthalmology peer-reviewed journals, professional societies, and eye health organizations, and to determine if there is a correlation between social media utilization and Twitter engagement metrics or journal impact measures. Methods We searched for online profiles of 100 ophthalmology peer-reviewed journals, 333 professional ophthalmology societies, and 40 eye health organizations on Facebook, Twitter, and Instagram. Impact was quantified by recording the number of “likes” on Facebook and number of followers on Twitter and Instagram. We also used Twitonomy software to obtain advanced Twitter metrics for all journal accounts from 2018 to 2021, and compared to journal impact measured by SCImago Journal Rank (SJR) score, the h-index, and impact factor. Results Eye health organizations averaged significantly greater Facebooks “likes” and Twitter followers than both peer-reviewed journals and professional societies (p < 0.0001). Of 100 journals studied, 30% were active on Twitter, 25% on Facebook, and 6% on Instagram. Slightly more than half of all journal-affiliated social media accounts were accessible from the journal website. Among journals with active Twitter accounts, total followers, total tweets, average retweets, and average “favorites” were all significantly positively correlated with academic metrics such as the SJR, h-index, and/or impact factor. Conclusion Greater social media engagement is associated with higher ophthalmology journal impact metrics; however, ophthalmology journals and professional societies lag behind eye health organizations in social media engagement. Although unable to demonstrate causality, social media may be an underutilized visibility, communication, and dissemination tool.

A diagnostic to measure neutral-atom density in fusion-research plasmas. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2022; 93:093519. [PMID: 36182459 DOI: 10.1063/5.0101683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 08/16/2022] [Indexed: 06/16/2023]
Abstract
A femtosecond two-photon-absorption laser-induced-fluorescence (TALIF) diagnostic was designed, installed, and operated on the Princeton-Field-Reversed Configuration-2 device to provide non-invasive measurements of the time and spatially resolved neutral-atom densities in its plasmas. Calibration of the Ho density was accomplished by comparison with Kr TALIF. Measurements on plasmas formed of either H2 or Kr fill gases allowed examination of nominally long and short ionization mean-free-path regimes. With multi-kW plasma heating and H2 fill gas, a spatially uniform Ho density of order 1017 m-3 was measured with better than ±2 mm and 10 µs resolution. Under similar plasma conditions but with Kr fill gas, a 3-fold decrease in the in-plasma Kr density was observed.

Abstract
A collisional-radiative (CR) model that extracts the electron temperature, Te, of hydrogen plasmas from Balmer-line-ratio measurements is examined for the plasma electron density, ne, and Te ranges of 1010-1015 cm-3 and 5-500 eV, respectively. The CR code, developed and implemented in Python, has a forward component that computes the densities of excited states up to n = 15 as functions of Te, ne, and the molecular-to-atomic neutral ratio r(H2/H). The backward component provides ne and r(H2/H) as functions of the Balmer ratios to predict the Te. The model assumes Maxwellian electrons. The density profiles of the electrons and of the molecular and atomic hydrogen neutrals are shown to be of great importance, as is the accuracy of the line-ratio measurement method.

Simulating single-particle dynamics in magnetized plasmas: The RMF code. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2022; 93:083506. [PMID: 36050065 DOI: 10.1063/5.0101665] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 06/30/2022] [Indexed: 06/15/2023]
Abstract
The RMF (Rotating Magnetic Field) code is designed to calculate the motion of a charged particle in a given electromagnetic field. It integrates Hamilton's equations in cylindrical coordinates using an adaptive predictor-corrector double-precision variable-coefficient ordinary differential equation solver for speed and accuracy. RMF has multiple capabilities for the field. Particle motion is initialized by specifying the position and velocity vectors. The six-dimensional state vector and derived quantities are saved as functions of time. A post-processing graphics code, XDRAW, is used on the stored output to plot up to 12 windows of any two quantities using different colors to denote successive time intervals. Multiple cases of RMF may be run in parallel and perform data mining on the results. Recent features are a synthetic diagnostic for simulating the observations of charge-exchange-neutral energy distributions and RF grids to explore a Fermi acceleration parallel to static magnetic fields.

Abstract
Fellowship program website content has been studied for some ophthalmological subspecialties; however, pediatric ophthalmology fellowship program websites have not been previously studied. Our cross-sectional analysis reveals that all US pediatric ophthalmology fellowship programs maintain an active website that is visible after Google search, which is not the case for all glaucoma, vitreoretinal surgery, or ophthalmic plastic and reconstructive surgery fellowship programs. Content on pediatric ophthalmology fellowship program websites varied widely, with program websites averaging only 12 ± 3.3 of 20 recruitment and education criteria evaluated (range, 3-18). Total number of fellows, number of clinical faculty, and geographic region did not affect fellowship program website content score. Fewer than half of fellowship program websites contained criteria often deemed important by applicants, including geographic placement of graduates, salary/benefits, and call schedule. Optimized recruitment and education content on fellowship programs websites may help applicants identify programs that best align with their career goals.

Relative Importance of Applicant Characteristics in Ophthalmology Residency Interview Selection: A Survey of Program Directors. JOURNAL OF ACADEMIC OPHTHALMOLOGY 2022. [DOI: 10.1055/s-0042-1756122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/05/2022] Open
Abstract
Abstract
Introduction Ophthalmology residency positions remain competitive. A lack of clarity regarding which residency selection criteria are prioritized by program directors can heighten the stress associated with the match process. While surveys of program directors in several other medical specialties have been conducted to identify the most important residency selection criteria, there is limited data on selection criteria used by ophthalmology residency program directors. The purpose of our study was to survey ophthalmology residency program directors to identify the current state of interview selection decisions—the factors currently considered most important in determining whether to extend an interview invitation to residency applicants.
Methods We developed and distributed a Web-based questionnaire to all U.S. ophthalmology residency program directors. Questions evaluated program demographics and the relative importance of 23 different selection criteria used by ophthalmology residency program directors when evaluating applicants for residency interviews (Likert scale 1–5, with 1 being “not important” and 5 being “very important”). Program directors were also asked to identify the one factor they felt was most important.
Results The overall residency program director response rate was 56.5% (70/124). The selection criteria with the highest average importance scores were core clinical clerkship grades (4.26/5) followed by letters of recommendation (4.06/5), and United States Medical Licensing Examination (USMLE) Step 1 score (4.03/5). The most frequently cited single most important factor for interview selection was core clinical clerkship grades (18/70, 25.7%), with USMLE Step 1 score (9/70, 12.9%) and rotations at the program director's department (6/70, 8.6%) also commonly reported.
Conclusion Our results suggest that core clinical clerkship grades, letters of recommendation, and USMLE Step 1 scores are deemed the most important selection criteria by ophthalmology residency program directors as of a 2021 survey. With changes in clerkship grading for many medical schools and changes in national USMLE Step 1 score reporting, programs will face challenges in evaluating applicants and the relative importance of other selection criteria will likely increase.

Limited Biomechanical Evidence Behind Single Row Versus Double Row Repair of Subscapularis Tears: A Systematic Review. Arthrosc Sports Med Rehabil 2022; 4:e1193-e1201. [PMID: 35747639 PMCID: PMC9210385 DOI: 10.1016/j.asmr.2022.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Accepted: 01/24/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose To systematically review the literature for studies investigating the biomechanical properties of constructs used to repair isolated subscapularis tears in time zero human cadaveric studies. Methods A systematic review was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three electronic databases were searched for studies that reported on the construct technique and biomechanical outcomes for the repair of isolated subscapularis tears in human cadaveric specimens. Ultimate load, gap formation, stiffness, and failure mode were documented. Methodological quality was assessed using the Quality Appraisal for Cadaveric Studies (QUACS) scale. Results Six articles qualified (104 shoulders [72 single-row, 26 double-row, 6 transosseous]; mean QUACS score 10.5 ± 1) and were analyzed. Studies varied in the number and type of anchors and construct technique (1-2 anchors single-row; 3-4 anchors double-row; bioabsorbable or titanium anchors) and suture(s) used (no. 2 FiberWire or FiberTape), subscapularis tear type (25%, 33%, 50%, or 100% tear), and whether a knotless or knotted fixation was used. In studies that created full-thickness, upper subscapularis tears (Fox-Romeo II/III or Lafosse II), no significant differences were seen in ultimate load, gap formation, and stiffness for knotted versus knotless single-row repair (2 studies) and single-row versus double-row repair (1 study). Double-row repair of complete subscapularis tears demonstrated higher ultimate load, stiffness, and lower gap formation in 1 study. Ultimate load differed between the studies and constructs (single-row: range, 244 N to 678 N; double-row: range 332 N to 508 N, transosseous: 453 N). Suture cutout was the most common mode of failure (59%). Conclusion Because of the limited number of studies and varying study designs in examining the biomechanical properties of repair constructs used for subscapularis tears, there is inconclusive evidence to determine which construct type is superior for repairing subscapularis tears. Clinical Relevance Results from biomechanical studies of clinically relevant subscapularis repair constructs are important to guide decision-making for choosing the optimal construct for patients with subscapularis tears.

Abstract
Abstract
Introduction Ophthalmology departments have been stated to be among the least diverse clinical departments at United States medical schools. Improvement requires recruiting a pipeline of diverse trainees. Residency program Web sites represent a potential diversity and inclusion recruitment tool. This study assesses how ophthalmology residency program Web sites demonstrate a commitment to diversity and inclusion.
Methods We analyzed the diversity and inclusion content of 116 ophthalmology residency program Web sites in April 2021. Main outcome measures were the presence of 12 diversity and inclusion elements on program Web sites, based on prior work and Accreditation Council for Graduate Medical Education guidelines: nondiscrimination statement, diversity and inclusion message, community resources, extended faculty or resident biographies (including hobbies, etc.), faculty photos, resident photos, additional financial resources for trainees, wellness resources, mental health resources, health disparities/community engagement, and diversity council. We used Mann–Whitney U and Kruskal–Wallis tests to assess whether residency program characteristics such as rank, size, university affiliation, and geographic location were associated with commitment to diversity and inclusion on affiliated residency Web sites.
Results Ophthalmology residency program Web sites included a mean of 4.4 ± 2.1 diversity elements. Sixteen percent of programs featured more than half (7 + ) of the evaluated diversity elements. The most featured common diversity elements included resident photos (85.3%), faculty photos (78.4%), and community resources (64.3%). Extended faculty biographies (2.6%), mental health resources (9.5%), and diversity council information (11.2%) were less commonly showcased. Top-ranked programs (7.6 ± 1.8, p < 0.0001) and university-based/-affiliated programs (4.7 ± 2.8, p = 0.0039) displayed more diversity elements than lower-ranked (4.1 ± 1.8) and community-based programs (2.8 ± 1.7).
Conclusion Most ophthalmology residency program Web sites feature less than half of the 12 diversity and inclusion elements included in this study, suggesting room for improvement. By drawing attention to program diversity and inclusion efforts, Web sites offer a potential tool for residency programs to consider in their recruitment efforts for diverse trainees. Incorporating the diversity and inclusion elements analyzed in this study represents a low-burden way to signal a greater commitment to diversity that could help programs recruit diverse applicants.

Abstract
BACKGROUND Plastic surgeons are increasingly turning to social media to market their services. The newly released Twitter Academic Research Product Track (TARPT) database provides free, customizable analysis of keywords that are included in tweets on the Twitter platform. The TARPT tool may provide valuable insight into public interest in cosmetic surgery procedures. OBJECTIVES The aim of this study was to determine TARPT's utility in tracking and predicting public interest in cosmetic surgery procedures and to examine temporal trends in tweets related to cosmetic facial and body procedures. METHODS The TARPT tool was used to calculate the total number of tweets containing keywords related to 10 facial cosmetic procedures and 7 cosmetic body procedures from 2010 to 2020. Annual volumes for respective procedures were obtained from annual statistics reports of The Aesthetic Society from 2010 to 2020. Tweet volumes and procedure volumes were compared by univariate linear regression, taking P < 0.05 as the cutoff for significance. RESULTS Variations in tweet volume were observed. Univariate linear regression analysis demonstrated statistically significant positive correlations between tweet volumes and procedure volumes for 7 search terms: "eyelid lift," "facelift," "lip injections," "mastopexy," "butt lift," "butt implants," and "liposuction." Many procedure-related keywords were not significant, demonstrating the importance of careful selection of Twitter search terms. CONCLUSIONS The TARPT database represents a promising novel source of information for plastic surgeons, with the potential to inform marketing and advertising decisions for emerging trends in plastic surgery interest before these patterns become apparent in surgical or clinical volumes.

Abstract
Abstract
Introduction The ophthalmology residency match remains competitive. Several prior studies have examined various factors that contribute to a successful match into an ophthalmology residency program; however, the role of geographic location in the ophthalmology residency match process is unclear. The purpose of our study was to evaluate geographic trends in the ophthalmology residency match and to determine whether geographic trends vary based on program level factors such as program rank or funding source and/or applicant factors such as year of training, gender, and medical degree earned. Specifically, we assessed associations with residents training at the residency program affiliated with their medical school and/or within the same geographic region as their medical school, using data obtained through publicly available sources and residency program surveys.
Methods We used the American Medical Association's Fellowship and Residency Electronic Interactive Database database to identify accredited ophthalmology residency programs. Residency program Web sites and email inquiries were used to collect demographic and geographic information for residents in the graduating classes of 2021 to 2023. Statistical analysis included χ2 testing and multivariate logistic regression.
Results In total, 1,378 residents were included from 110 ophthalmology residency programs and 218 medical schools. Residents who matched at the residency program affiliated with their medical school (18%) were evenly distributed among the Midwest, Northeast, South, and West regions (p = 0.2236). Residency programs in the West (31.7%) matched fewer regional medical students compared with programs in the South (61.2%), Midwest (57.4%), and Northeast (58.4%) (p < 0.0001). Attending a publicly funded medical school was associated with higher odds of matching into a regional residency program (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.10–1.90; p = 0.0001) and attending a privately funded medical school was associated with higher odds of matching into a top-ranked residency program (OR, 1.53, 95% CI, 1.34–1.82; p = 0.0002).
Conclusions The majority of current ophthalmology residents trained at programs in the same geographic region as their medical schools, with nearly 20% of residents training at their medical school-affiliated program. Geographic differences in match results were observed based on resident gender, medical school characteristics, and residency program region.

Using Pitch-Tracking Data to Identify Risk Factors for Medial Ulnar Collateral Ligament Reconstruction in Major League Baseball Pitchers. Orthop J Sports Med 2022; 10:23259671211065756. [PMID: 35284587 PMCID: PMC8905067 DOI: 10.1177/23259671211065756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 09/20/2021] [Indexed: 11/23/2022] Open
Abstract
Background: Approximately 25% of Major League Baseball (MLB) pitchers undergo medial ulnar collateral ligament reconstruction (UCLR) during their careers. Purpose: To identify risk factors for UCLR that are specific to 2 subgroups of MLB pitchers: right (RHPs)- versus left-handed pitchers (LHPs) and starting (SPs) versus relief pitchers (RPs). Study Design: Case-control study; Level of evidence, 3. Methods: We included 109 MLB pitchers who had undergone UCLR between 2007 and 2019 and had sufficient preinjury data in the 3 years before surgery (T3, T2, T1). A 2:1 matched control cohort was selected for comparison. Pitch velocity, release location, and ball movement were compared between the UCLR and control cohorts in both subgroups in the years before surgery (RHPs vs LHPs and SPs vs RPs). Binary logistic regression was used to identify independent risk factors for UCLR. Results: The mean horizontal release location for the UCLR group was 5.8 cm more lateral than for the control group (P = .028). For all pitchers, every 2.5-cm lateral shift in release location in the years leading up to UCLR equated to a 3.7% increase in the odds of UCLR. For RPs, this risk was more substantial: a 5.8% increase in odds per 2.5 cm. SPs in the UCLR group demonstrated significantly different T1 horizontal release locations compared with SPs in the control group, though not to a statistically significant change over the 3 years before surgery. However, in the 3 years before surgery, the horizontal release location for RPs in the UCLR group moved 2.1 cm more lateral, as compared with 2.7 cm more medial for RPs in the control group (P = .007). For LHPs, a decrease in mean pitch velocity by 1 mph (1.6 km/h) in the years leading up to surgery increased the odds of UCLR by 45%. Conclusion: Increasing lateralization of release point in the years before surgery increased the risk of UCLR, specifically for relievers. Our findings add to the growing body of evidence that release location is an important variable in analyzing the risk of UCLR in MLB and that risk stratification may be dependent on pitcher characteristics such as position, handedness, and weight.

Abstract
BACKGROUND The shift to virtual interviews during the COVID-19 pandemic has elevated the vital role of Accreditation Council for Graduate Medical Education residency program websites in conveying information to applicants. The purpose of our study was to assess the recruitment, education, and diversity and inclusion content on websites for anesthesiology residency programs. Second, we aimed to test the hypothesis that the content scores of websites are higher in programs with more National Institutes of Health funding, in programs that are university-based versus community-based, and in larger programs, as measured by number of residents. METHODS Two independent reviewers evaluated the websites of the 159 anesthesiology residency programs accredited by the Accreditation Council for Graduate Medical Education for the presence (yes/no) of 12 recruitment, 6 education, and 8 diversity and inclusion criteria. Multiple linear regression was used to determine which program factors were most associated with total website content score. RESULTS Anesthesiology residency program websites contained a mean of 12.9 (SD = 3.4; range, 3-21) of the 26 study-defined criteria. The most common recruitment, education, and diversity and inclusion criteria were, respectively, program description, rotation information, and community demographics. Controlling for program factors, a university-based affiliation (P = .016) was associated with higher website content scores. CONCLUSIONS There is large variation in the recruitment, education, and diversity and inclusion content on anesthesiology residency program websites nationally. Since program websites averaged only half of criteria, this may provide an impetus for programs to modify their websites, which may inform applicant decisions about which programs align with their training and career goals.

Online public interest in common malignancies and cancer screening during the COVID-19 pandemic in the United States. J Clin Transl Res 2021; 7:723-732. [PMID: 34901518 PMCID: PMC8654364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Revised: 09/29/2021] [Accepted: 09/29/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND AND AIM The COVID-19 pandemic was declared a national emergency in the United States in March 2020. The Centers for Medicare and Medicaid Services subsequently released recommendations that health-care facilities temporarily delay elective surgeries and non-essential medical procedures. Disruptions to medical care significantly impacted cancer patients, with cancer screenings halted and nonurgent cancer surgeries postponed as health-care facilities shifted resources toward the COVID-19 pandemic. Although it has been reported that cancer screening rates decreased dramatically in the United States in 2020, it is unclear whether this trend was driven by factors related to public interest in cancer and/or cancer screening as opposed to other factors such as clinical backlogs, pandemic-related policies, and/or resource limitations. The purpose of this study was to use the Google Trends tool to evaluate public interest in six common malignancies and four common cancer screening methods during the COVID-19 pandemic. METHODS We used the Google Trends tool to quantify public interest in six different malignancies (Breast Cancer, Colon Cancer, Lung Cancer, Prostate Cancer, Thyroid Cancer, and Cervical Cancer) and four cancer screening methods (Pap Smear, Lung Cancer Screening, Mammogram, and Colonoscopy) in the United States during the COVID-19 pandemic. Welch's t-tests were used to compare monthly search volumes during the COVID-19 pandemic (2020) to the 4 years before the pandemic (2016 - 2019) for all ten search terms included in our study. We used Benjamini-Hochberg to adjust raw p values to account for multiple statistical comparisons. The level of statistical significance was defined by choosing a false discovery rate of 0.05. RESULTS Our results indicate significantly reduced interest in all malignancies studied at the beginning of the COVID-19 pandemic. Public interest in ['Breast Cancer'], ['Colon Cancer'], ['Lung Cancer'], ['Thyroid Cancer'], and ['Cervical Cancer'] significantly decreased in the months of March, April, May, and June 2020 when compared with public interest in 2016-2019. Public interest in cancer screening methods such as ['Pap Smear'], ['Lung Cancer Screening'], ['Mammogram'], and ['Colonoscopy'] significantly deceased in the months of April and May compared to 2016 - 2019 values. However, decreased public interest in cancer screening methods was temporary, with Google search volumes returning to pre-pandemic levels in June 2020 - December 2020. CONCLUSION There was significantly reduced public interest in both common malignancies and cancer screening methods at the beginning of the COVID-19 pandemic in the United States. However, after an initial decline, public interest as indicated by Google search volumes quickly returned to pre-pandemic levels in the second half of the calendar year 2020. In addition, trends in public interest in cancer screening as indicated by Google search volumes aligned with cancer screening uptake rates in the United States during the study period. This finding suggests that Google Trends may serve as an effective tool in gauging the public's interest in cancer and/or cancer screenings in the United States, which makes it a valuable resource that can be used to inform decisions aimed at improving cancer screening rates in the future. RELEVANCE FOR PATIENTS The Google Trends tool can be used to measure public interest in various malignancies and their associated screening methods. Google Trends data may be used to inform measures aimed at improving cancer screening uptake.

Pain management in shoulder arthroplasty: a systematic review and network meta-analysis of randomized controlled trials. J Shoulder Elbow Surg 2021; 30:2638-2647. [PMID: 34284094 DOI: 10.1016/j.jse.2021.06.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 05/29/2021] [Accepted: 06/07/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Postoperative pain management after total shoulder arthroplasty (TSA) can be challenging. Given the variety of pain management options available, the purpose of this investigation was to systematically review the literature for randomized controlled trials reporting on pain control after shoulder arthroplasty. We sought to determine which modalities are most effective in managing postoperative pain and reducing postoperative opioid use. METHODS A systematic review was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched for Level I-II randomized controlled trials that compared interventions for postoperative pain control after TSA. Pain control measures included nerve blocks and nerve block adjuncts, local injections, patient-controlled analgesia, oral medications, and other modalities. The 2 primary outcome measures were pain level measured on a 0-10 visual analog scale and opioid use. The risk of study bias and methodologic quality were analyzed using The Cochrane Collaboration's Risk of Bias 2 (RoB 2) tool. Network meta-analyses were performed for visual analog scale pain scores at postsurgical time points and opioid use using a frequentist approach and random-effects model, with heterogeneity quantified using the I2 statistic. Treatments were ranked using the P score, and statistical significance was set at P < .05. RESULTS The initial search yielded 2391 articles (695 duplicates, 1696 screened, 53 undergoing full-text review). Eighteen articles (1358 shoulders; 51% female patients; mean age range, 65-73.7 years; 4 studies with low risk of bias, 12 with some risk, and 2 with high risk) were included and analyzed. At 4 and 8 hours postoperatively, patients receiving local liposomal bupivacaine (LB) injection (P < .001 for 4 and 8 hours) or local ropivacaine injection (P < .001 for 4 hours and P = .019 for 8 hours) had significantly more pain compared with patients who received either a continuous interscalene block (cISB) or single-shot interscalene block (ssISB). No differences in opioid use (at P < .05) were detected between modalities. The P scores of treatments demonstrated that ssISBs were most favorable at time points < 24 hours, whereas pain at 24 and 48 hours after surgery was best managed with cISBs or a combination of an ssISB with a local LB injection. CONCLUSION Interscalene blocks are superior to local injections alone at managing pain after TSA. Single-shot interscalene blocks are optimal for reducing early postoperative pain (< 24 hours), whereas pain at 24-48 hours after surgery may be best managed with cISBs or a combination of an ssISB with a local LB injection.

Differentiating Upper Extremity Necrotizing Soft Tissue Infection From Serious Cellulitis and Abscess. Cureus 2021; 13:e17806. [PMID: 34660016 PMCID: PMC8500241 DOI: 10.7759/cureus.17806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/07/2021] [Indexed: 12/02/2022] Open
Abstract
Introduction Necrotizing soft tissue infection (NSTI) of the upper extremity (UE) is a rapidly progressing infection that requires early diagnosis and emergent treatment to decrease risks of loss of limb or life. Clinical presentation, particularly of early NSTI, can appear similar to serious cellulitis or abscess. The purpose of this study was to identify factors that are associated with NSTI rather than serious cellulitis and abscess to differentiate patients with similar clinical presentations. Methods This study uses a retrospective cohort design that compares patients ultimately diagnosed with UE NSTI versus those diagnosed with UE serious cellulitis or abscess. Cohorts were matched using the Laboratory Risk Indicators for Necrotizing Fasciitis (LRINEC) score in the setting of UE soft tissue infection. Laboratory values, vital signs, subjective symptoms, and social factors including substance abuse and domiciled status were recorded. Continuous variables were compared using the Mann-Whitney U test, whereas categorical variables were compared using the chi-squared test or the Fisher exact test (for expected values less than 5). A binary logistic regression for continuous and categorical variables was also performed. Significance was set at p<0.05. Univariate and multivariate analyses were performed. Results Multivariate statistical analysis and clinical interpretation of data identified four factors more associated with a diagnosis of NSTI than serious cellulitis or abscess: elevated lactate on hospital presentation, a patient-reported history of fever, male gender, and homelessness. Conclusions In patients with upper extremity infections, the clinical presentation of NSTI and serious cellulitis or abscess may appear similar. In this retrospective cohort of patients matched with LRINEC scores, elevated lactate, subjective fever, male gender, and homelessness were significantly associated with NSTI rather than serious cellulitis or abscess.

Google Trends Analysis Shows Increasing Public Interest in Platelet-Rich Plasma Injections for Hip and Knee Osteoarthritis. J Arthroplasty 2021; 36:3616-3622. [PMID: 34172346 PMCID: PMC8478783 DOI: 10.1016/j.arth.2021.05.040] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/15/2021] [Accepted: 05/29/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Osteoarthritis is a chronic musculoskeletal condition that frequently affects the hip and knee joints. Given the burden associated with surgical intervention for hip and knee osteoarthritis, patients continue to search for potential nonoperative treatments. One biologic therapy with mixed clinical and basic science evidence for treating osteoarthritis is platelet-rich plasma injections into the affected joint. We used the Google Trends tool to provide a quantitative analysis of national interest in platelet-rich plasma injections for hip and knee osteoarthritis. METHODS Google Trends parameters were selected to obtain search data from January 2009 to December 2019. Various combinations of "arthritis," "osteoarthritis," "PRP," "platelet-rich plasma," "knee," and "hip" were entered into the Google Trends tool and trend analyses were performed. RESULTS Three linear models were generated to display search volume trends in the United States for platelet-rich plasma and osteoarthritis, hip osteoarthritis, and knee osteoarthritis, respectively. All models showed increased Google queries as time progressed (P < .001), with R2 ranging from 0.837 to 0.940. Seasonal, income-related, and geographic variations in public interest in platelet-rich plasma for osteoarthritis were noted. CONCLUSION Our results demonstrate a significant rise in Google queries related to platelet-rich plasma injections for osteoarthritis of the hip and knee since 2009. Surgeons treating hip and knee osteoarthritis patients can expect continued interest in platelet-rich plasma, despite inconclusive clinical and basic science data. Trends in public interest may inform patient counseling, shared decision-making, and directions for future clinical research.

An Update on the Accessibility and Quality of Online Information for Pediatric Orthopaedic Surgery Fellowships. Cureus 2021; 13:e17802. [PMID: 34660012 PMCID: PMC8497116 DOI: 10.7759/cureus.17802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/07/2021] [Indexed: 11/26/2022] Open
Abstract
Introduction The internet is an important tool for applicants seeking information on pediatric orthopaedic surgery fellowship programs. Previous analysis of pediatric orthopaedic surgery fellowship websites demonstrated they were often inaccessible and incomplete. As such, the purpose of this study was to (1) perform an updated assessment of the accessibility and content of pediatric orthopaedic fellowship program websites and (2) compare the results to the previous study to discern temporal trends in website accessibility and quality. Methods A list of pediatric orthopaedic fellowship programs was compiled from the San Francisco Match (SF Match) and the Pediatric Orthopaedic Society of North America (POSNA) online databases. All identified websites were evaluated for (1) accessibility and (2) the presence of 12 education and 12 recruitment criteria. These criteria were determined by prior fellowship website analyses and the needs of current fellowship applicants. Website accessibility and quality were compared with previously reported metrics. Results Approximately 91% of pediatric orthopaedic surgery fellowship programs had a functioning website. While the SF Match and POSNA databases listed nearly identical programs, there were discrepancies in the information provided by the two databases, and individual program website links provided on both databases were often nonfunctional. Fellowship program websites contained an average of 15.1 ± 3.9 total education and recruitment criteria (range: 3 - 21). The most common education criteria featured on program websites included information about research, affiliated hospital information, and rotations. The most common recruitment criteria featured on program websites included program descriptions, contact information, and social media links. There was an increased frequency in nearly all education and recruitment criteria evaluated when compared with 2014 metrics. Discussion Although website accessibility and content have improved since 2014, information on pediatric orthopaedic fellowship program websites remains incomplete, with many websites failing to provide information on criteria deemed important by fellowship applicants. In addition, many discrepancies exist between the SF Match and POSNA databases, the two primary sources of information for pediatric orthopaedic fellowship applicants. Increased consistency on pediatric orthopaedic fellowship websites and both the SF Match and POSNA databases may help applicants to better assess which programs to apply to and which programs to rank highly on their match list.

Google trends as a tool for evaluating public interest in total knee arthroplasty and total hip arthroplasty. J Clin Transl Res 2021; 7:456-466. [PMID: 34667892 PMCID: PMC8520707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 06/16/2021] [Accepted: 06/16/2021] [Indexed: 11/07/2022] Open
Abstract
BACKGROUND AND AIMS There are approximately 1 million total knee arthroplasty (TKA) and total hip arthroplasty (THA) procedures performed annually in the United States. With this number projected to increase, it is vital for orthopedic surgeons and health-care systems to properly anticipate healthcare utilization related to TKA and THA. Google Trends (GT) is a free, open source tool that provides customizable analysis of search terms entered into the Google search engine. We aim to explore the relationship between public interest in TKA and THA as determined by GT data and volume of TKA and THA procedures. METHODS GT data were compiled for ten search terms related to TKA and ten search terms related to THA from January 2009 to December 2017. Annual case volumes for TKA/THA procedures were obtained from the Healthcare Cost and Utilization Project National Inpatient Sample from 2009 to 2017. Trend analysis was performed using univariate linear regression of GT data and TKA/THA case volumes. RESULTS There was a statistically significant positive correlation between GT data and procedure volume for 14 of the 20 search terms studied. Seven TKA-related search terms with a positive correlation to procedure volumes include "total knee replacement," "knee replacement," "knee osteoarthritis," "knee ache," "knee swelling," "knee stiffness," and "chronic knee pain." Seven THA-related search terms with a positive correlation to procedure volumes include "hip arthroplasty," "total hip replacement," "hip replacement," "hip osteoarthritis," "hip ache," "hip swelling," and "chronic hip pain." CONCLUSION GT may provide a high utility as a convenient and informative data set for orthopedic surgeons to analyze public interest in TKA and THA procedures. The data provided by GT have the potential to provide real-time, actionable information that may help surgeons and health systems to characterize public interest in TKA and THA and to best identify and address patient needs. RELEVANCE FOR PATIENTS The GT tool can be used to measure public interest in TKA/THA, which can inform physician expectations for the patient encounter and lead to the creation of decision aids that better inform the public about the risks and benefits of TKA/THA.

Abstract
Background Google Trends (GT) is a free tool that provides analysis of search traffic for specified terms entered into the Google search engine. In this study, we evaluate the association between public interest in hand osteoarthritis (OA) as determined by GT search volumes and healthcare usage related to hand OA. Methodology We compiled GT data from 2010 to 2017 for the following group of hand OA-related search terms: “hand osteoarthritis,” “hand arthritis,” “hand swelling,” “hand stiffness,” and “chronic hand pain.” Claims associated with hand OA codes were obtained from an administrative database (14.8 million patients) using International Classification of Diseases codes from 2010 to 2017. We performed trend analysis using univariate linear regression of GT data and hand OA claims. A month-by-month analysis of variation from yearly GT means was conducted for hand OA-related search terms. Results There was increased public interest in hand OA-related search terms from January 2010 to December 2017. Univariate linear regression of GT data for hand OA-related search terms compared with hand OA claims demonstrated a significant positive correlation (p < 0.001, r = 0.707). Peak public interest in hand OA-related search terms was observed in July, May, and June. Conclusions This study demonstrates the ability of GT to track healthcare use related to hand OA. Our data also add to the evidence for monthly variations in public interest related to hand OA. Clinics and surgery centers can employ GT data to anticipate resource utilization by hand OA patients.

Abstract
The novel coronavirus SARS-CoV-2 emerged in China in 2019 and quickly spread globally, causing a pandemic. There is an urgent need to develop vaccines against the virus, and both convalescent plasma and immune globulin are currently in clinical trials for treatment of patients with COVID-19. It is unclear whether antibodies induced by SARS-CoV-2 have neutralizing capacity and whether they can protect from future infection. Seasonal human coronaviruses (HCoV) have been circulating for decades. It is currently unknown whether antibodies against seasonal HCoV may cross-neutralize SARS-CoV-2. Data from neonates suggest that trans-placental antibodies against HCoV may have neutralizing capacity. Here we briefly review the epidemiologic observations on HCoV and discuss the potential implications for neutralizing and cross-neutralizing antibodies against SARS-CoV-2.

Abstract
Introduction Precautions issued by organizations such as the American Academy of Orthopaedic Surgeons (AAOS) recommending against any elective, or non-essential, surgical procedures have significantly affected healthcare resource utilization by the public during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. In this study, we demonstrate the value of the Google Trends (GT) interface to characterize and monitor in real-time the response in public interest toward various elective orthopedic procedures. Methods Search volume databases were generated from January 2015 to May 2020 for keywords related to anterior cruciate ligament (ACL) reconstruction, elbow arthroplasty, hip arthroplasty, knee arthroplasty, and rotator cuff repair. To measure the immediate effects on public interest, the percent change was calculated from the AAOS, and Centers for Medicare and Medicaid Services (CMS) defined a 30-day pre-recommendations period to a 30-day post-recommendations period. To measure long-term effects, mean search volumes from January 1, 2015, to February 29, 2020, were compared to mean search volumes from March 1, 2020, to May 21, 2020. Results In the 30-day period following statements by the AAOS and CMS, interest in all search terms except “partial knee arthroplasty” decreased as follows: “ACL reconstruction” (-32.7%); “ACL repair” (-22.6%); “anterior cruciate ligament reconstruction” (-39.8%); “elbow arthroplasty” (-17.2%); “elbow joint replacement” (-15.1%); “total elbow arthroplasty” (-40.0%); “hip arthroplasty” (-23.0%); “hip replacement” (-41.2%); “total hip arthroplasty” (-23.0%); “knee arthroplasty” (-43.0%); “total knee arthroplasty” (-33.3%); “rotator cuff repair” (-34.2%); “rotator cuff surgery” (-50.6%); “shoulder arthroplasty” (-26.7%). Discussion GT data have previously demonstrated utility in characterizing and anticipating shifts in real-world healthcare utilization, making it an invaluable tool for physicians to anticipate and address the emerging needs of our patient population. Our study further illustrates the value of GT in localizing rapidly recovering interest in several of the most common elective orthopedic surgeries, enabling surgeons with up-to-date actionable data to guide the management of practices and healthcare facilities as the US slowly emerges from precautions endorsed during the COVID-19 pandemic.

The impact of monthly campaigns and other high-profile media coverage on public interest in 13 malignancies: a Google Trends analysis. Ecancermedicalscience 2020; 14:1154. [PMID: 33574899 PMCID: PMC7864687 DOI: 10.3332/ecancer.2020.1154] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Indexed: 01/13/2023] Open
Abstract
It is estimated that more than 600,000 people will die of cancer in the United States in 2020. Annual cancer diagnoses throughout the country are expected to rise in the coming years, which may further strain the American healthcare system. As such, it is vital that public health campaigns intended to reduce cancer morbidity and mortality are successful. Monthly cancer awareness campaigns have been used in the past to raise awareness and funding for various malignancies. One notable example is the 'Pink October' campaign to raise awareness for breast cancer. There has been limited study, however, on the effectiveness of cancer awareness campaigns for other cancers such as colorectal cancer, prostate cancer and cervical cancer. High-profile media coverage of celebrity cancer diagnoses and/or cancer-related deaths is another method by which knowledge of common cancers is dispersed to the public. In this study, we evaluate the impact of monthly cancer awareness campaigns as well as celebrity cancer diagnoses and/or deaths on Internet search traffic regarding various malignancies. We used the Google Trends database to evaluate public interest in 13 different cancers (and their respective cancer screening methods, when applicable) from January 2010 to June 2020. Public interest in 6 of 13 cancers (cervical cancer, colorectal cancer, skin cancer, ovarian cancer, breast cancer and lung cancer) was significantly higher in their respective awareness months when compared to the rest of the year. Furthermore, peak public interest for 9 of 13 cancers was associated with a media-event such as a monthly awareness campaign or celebrity diagnoses and/or death. Our findings illustrate the important role that the media plays in facilitating public interest in common cancers and their screening methods. Cancer awareness months can serve as an effective tool to increase Internet search traffic regarding a given malignancy. In the future, public health agencies can attempt to utilise increased search traffic to better educate the public, raise funds and improve enrolment in cancer screening programmes that reduce cancer morbidity and mortality.

Abstract
BACKGROUND Physical activity reduces the likelihood of developing metabolic syndrome (MetS). However, the association between different physical activity levels and MetS remains unclear in older adults with obesity. METHODS This cross-sectional study used four waves of data (2007-2008, 2009-2010, 2011-2012, 2013-2014) from two datasets: The National Health and Nutrition Examination Survey and United Sates Department of Agriculture's Food Patterns Equivalents Database. The sample included adults 60+ years of age (n= 613) with obesity who had physical activity and MetS data. Physical activity was assessed using the Global Physical Activity Questionnaire and categorized into three physical activity levels (low, medium, and high); and medium or high physical activity levels are aligned with or exceed current physical activity recommendations. Participants were classified as having MetS using a commonly agreed upon definition. Multiple logistic regression models examined the association between the three physical activity levels and MetS risk factors and MetS. All analyses adjusted for potential confounding variables and accounted for complex sampling. RESULTS Of 613 respondents, 72.1% (n=431) were classified as having MetS, and 44.3% (n = 263) had not met physical activity recommendations. Participants with high levels of physical activity had a lower risk of MetS (OR = 0.31, 95%CI: 0.13, 0.72) and more healthful levels of high-density lipoprotein cholesterol (OR = 0.39, 95%CI: 0.18, 0.84), blood pressure (OR = 0.39, 95%CI: 0.20, 0.77), fasting glucose (OR = 0.34, 95%CI: 0.15, 0.78) than participants categorized as having low physical activity. CONCLUSIONS Physical activity is associated with lower risk of MetS only for participants with the highest level of physical activity, which suggests that physical activity dosage is important to reduce MetS risk in older adults with obesity.

Abstract
OBJECTIVE To identify community resource needs among families presenting to a pediatric emergency department (PED). METHODS A convenience sample of English- and Spanish-speaking caregivers residing in Los Angeles County who presented to the PED of a large urban children's hospital were surveyed. The needs assessment survey assessed demographics, food insecurity, and previous and anticipated need for 12 common community resources. RESULTS Of 768 caregivers who completed the survey, 75% identified as Hispanic/Latinx. Across all survey participants, 83% used at least 1 resource in the past, and 67% anticipated needing at least 1 resource in the next 12 months. Low-cost/free health clinics were the most common resources used in the past and needed for the future. Caregivers with younger children tended to need baby formula/breastfeeding and women's health resources, whereas caregivers with older children tended to need safe housing, subsidized utilities, and counseling/therapy. Many families who needed resources in the past and for the future resided south of the children's hospital where median household income was relatively lower than in other areas of the county. A pattern of heightened use emerged among caregivers who primarily spoke Spanish. On average, caregivers reported feeling comfortable approaching hospital staff about community resources. CONCLUSIONS We found significant needs for community resources among families who presented to an urban PED. Needs were particularly salient among Spanish-speaking families and families living in close proximity to the children's hospital. Findings from this study help to inform future work connecting families to community resources.

Abstract
BACKGROUND A growing body of research shows that diet quality and physical activity (PA) are associated with health-related quality of life (HRQOL). However, no study to date has assessed this association using the Healthy Eating Index-2015 as a measure of diet quality. Furthermore, few studies have examined the association between PA dose and HRQOL among a nationally representative sample of older adults. OBJECTIVES To investigate the relationship between diet quality, physical activity, and HRQOL. DESIGN A cross-sectional analysis was conducted using data obtained from 5,311 adults aged 60+ years who took part in the National Health and Nutrition Examination Survey between 2007 and 2014. MEASUREMENTS HRQOL was assessed by general health status, and number of physically unhealthy days, mentally unhealthy days, and inactive days in past 30 days. Diet quality was assessed by the Healthy Eating Index-2015 using data generated by two 24-hour dietary recalls. PA was measured by the Global Physical Activity Questionnaire. Multivariate logistic/or linear regression models were used to examine the association between diet quality, PA and HRQOL controlling for confounders and accounting for complex sampling. RESULTS Approximately half of the participants (55.2%) were women, 45.1% met current PA recommendations, 65% had less healthful diets according to the Healthy Eating Index-2015. Diet quality was associated with HROQL. For every 1-point diet quality score increase, the likelihood of respondents rating their general health as being excellent/good increased by 3% (OR=1.03, 95%CI: 1.02, 1.04), and number of inactive days (β =-0.03, 95%CI: -0.05, 0.00) and mental unhealthy days (β =-0.03, 95%CI: -0.05, -0.01) declined by 0.03 days. PA was associated with all HROQL measures and respondents with high PA levels reported better general health (OR=3.53, 95%CI: 2.69, 4.63), fewer inactive days (β =-1.53, 95%CI: -2.11, -0.95), fewer physical unhealthy days (β =-1.88, 95%CI: -2.74, -1.02) than individuals with low PA levels but not fewer mentally unhealthy days. CONCLUSIONS Among older adults in this study, eating a healthier diet and being physically active were associated with better general health and reporting fewer physical unhealthy days and inactive days. Study results provide valuable information that could inform policies, programs and interventions designed to improve HRQOL in older adults and reduce potentially preventable health disparities.

Incidence and outcomes of bloodstream infections among hematopoietic cell transplant recipients from species commonly reported to be in over-the-counter probiotic formulations. Transpl Infect Dis 2016; 18:699-705. [PMID: 27501401 DOI: 10.1111/tid.12587] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2016] [Revised: 05/23/2016] [Accepted: 06/05/2016] [Indexed: 12/19/2022]
Abstract
BACKGROUND Probiotic supplementation has been promoted for numerous health conditions; however, safety in immunosuppressed patients is unknown. We evaluated bloodstream infections (BSIs) caused by common probiotic organisms in hematopoietic cell transplant recipients. METHODS All blood culture (BC) results from a cohort of hematopoietic cell transplant recipients transplanted at Fred Hutchinson Cancer Research Center in Seattle, Washington, between 2002 and 2011 were reviewed. Patients with at least 1 positive BC for common probiotic organisms (Lactobacillus species, Bifidobacterium species, Streptococcus thermophilus, and Saccharomyces species) within 1 year post hematopoietic cell transplantation (HCT) were considered cases. Data were collected from center databases, which contain archived laboratory data, patient demographics, and clinical summaries. RESULTS A total of 19/3796 (0.5%) patients developed a BSI from one of these organisms within 1 year post HCT; no Bifidobacterium species or S. thermophilus were identified. Cases had a median age of 49 years (interquartile range [IQR]: 39-53), and the majority were allogeneic hematopoietic cell transplant recipients (14/19, 74%). Most positive BCs were Lactobacillus species (18/19) and occurred at a median of 84 days (IQR: 34-127) post transplant. The incidence rate of Lactobacillus bacteremia was 1.62 cases per 100,000 patient-days; the highest rate occurred within 100 days post transplant (3.3 per 100,000 patient-days). Eight patients (44%) were diagnosed with acute graft-versus-host disease of the gut prior to the development of bacteremia. No mortality was attributable to any of these infections. CONCLUSION Organisms frequently incorporated in available over-the-counter probiotics are infrequent causes of bacteremia after HCT. Studies evaluating the use of probiotics among high-risk patients are needed.

Examining trends in the treatment of ureterocele yields no definitive solution. J Pediatr Urol 2015; 11:29.e1-6. [PMID: 25459387 DOI: 10.1016/j.jpurol.2014.09.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2014] [Accepted: 09/21/2014] [Indexed: 10/24/2022]
Abstract
INTRODUCTION The surgical management of ureteroceles is extremely variable. Some have hypothesized that if these patients were treated with 'definitive' staged surgical intervention, the need for further revision surgery would be eliminated. OBJECTIVE The present study sought to determine if the rate of revision surgery differed among patients who have undergone different surgical approaches for the ureterocele complex. STUDY DESIGN A large retrospective chart review was conducted, identifying all patients having undergone ureterocele surgery at a single institution over the past 41 years. The cohort was divided into four groups based on surgical approach: upper tract approach (UTA), lower tract reconstruction (LTR), simultaneous upper and lower tract approach (ULTA), and staged lower tract reconstruction (SLTR). Demographics, the presence of preoperative/postoperative VUR, postoperative morbidity and the need for revision surgery were compared using the Chi- squared test, Fisher's exact test, Kruskal-Wallis test, Mann-Whitney U test (Bonferroni correction), logistic regression modeling and survival analyses (Kaplan-Meier and Cox proportional Hazards regression with unplanned revision operation as the outcome event). RESULTS Between 1969 and 2010, 180 patients were identified as having undergone surgical management of ureteroceles, of which 120 had complete demographic data available for analysis. The median age at the time of initial surgical intervention was 5.8 months and the majority of patients (83.3%) were female. The median follow-up was 33.1 months. Surgical management was as follows: 18 (15.0%) patients underwent UTA, 47 (39.2%) underwent LTR, 23 (19.2%) underwent ULTA, and 32 (26.6%) underwent SLTR. Among these groups, the only difference in median age was between the LTR and SLTR groups (6.3 months vs 3.7 months, P=0.012). Additional revision surgery was required in: nine (50.0%) of UTA, ten (21.3%) of LTR, four (17.4%) of ULTA, and three (9.4%) of SLTR. The only statistically significant difference in unplanned revision surgery was noted in the UTA group versus each of the other groups with VUR as the predominant indication (88.9%). The likelihood of requiring revision surgery in comparison to the SLTR group was significantly increased in the UTA group (OR 9.67, CI 2.15-43.56), but not in the LTR (OR 2.61, CI 0.66-10.37) or the ULTA group (OR 2.04, CI 0.41-10.13). Obstruction, recurring UTIs and VUR were the main indications for revision surgery overall. DISCUSSION There is a large body of literature examining the surgical management of ureteroceles. It most recently primarily focuses on an endoscopic approach to the lower tract. The present retrospective review examined the need for re-operative intervention by comparing four different surgical approaches, and found that there is no panacea. Although heminephrectomy (UTA) was a definitive procedure in some patients without reflux at presentation, many who underwent heminephrectomy, went on to require later bladder surgery for either recurrent UTI or persistent reflux. The present study has multiple limitations. Although VUR was an indication for revision surgery in the early part of the series, the current treatment of VUR is not necessarily as stringent. In addition, no distinction was made between an orthotopic or ectopic ureterocele, although some authors have reported differing outcomes in these two groups. However, it is felt that given the large data set of a relatively uncommon condition, the lack of superiority of one approach is apparent. CONCLUSION There is no definitive surgical repair for the ureterocele complex. All groups except UTA had statistically similar rates of revision surgery. The widespread variability in current management echoes the lack of one superior approach found in this comprehensive series.

Abstract
We describe ab initio, self-consistent, 3D, fully electromagnetic numerical simulations of current drive and field-reversed-configuration plasma formation by odd-parity rotating magnetic fields (RMF{o}). Magnetic-separatrix formation and field reversal are attained from an initial mirror configuration. A population of punctuated-betatron-orbit electrons, generated by the RMF{o}, carries the majority of the field-normal azimuthal electrical current responsible for field reversal. Appreciable current and plasma pressure exist outside the magnetic separatrix whose shape is modulated by the RMF{o} phase. The predicted plasma density and electron energy distribution compare favorably with RMF{o} experiments.

Formation of collisionless high-beta plasmas by odd-parity rotating magnetic fields. PHYSICAL REVIEW LETTERS 2007; 98:145002.

Abstract
Odd-parity rotating magnetic fields (RMFo) applied to mirror-configuration plasmas have produced average electron energies exceeding 200 eV at line-averaged electron densities of approximately 10(12) cm-3. These plasmas, sustained for over 10(3)tauAlfven, have low Coulomb collisionality, vc* triple bond L/lambdaC approximately 10(-3), where lambdaC is the Coulomb scattering mean free path and L is the plasma's characteristic half length. Divertors allow reduction of the electron-neutral collision frequency to values where the RMFo coupling indicates full penetration of the RMFo to the major axis.

Onset and saturation of ion heating by odd-parity rotating magnetic fields in a field-reversed configuration. PHYSICAL REVIEW LETTERS 2006; 96:015002.

Abstract
Heating of figure-8 orbit ions by odd-parity rotating magnetic fields (RMF(O)) applied to an elongated field-reversed configuration (FRC) is investigated. The largest energy gain occurs at resonances (s congruent to omega(R)/omega) of the RMF(O) frequency, omega(R), with the figure-8 orbital frequency, omega, and is proportional to s2 for s-even resonances and to s for s-odd resonances. The threshold for the transition from regular to stochastic orbits explains both the onset and saturation of heating. The FRC magnetic geometry lowers the threshold for heating below that in the tokamak by an order of magnitude.

Abstract
STUDY DESIGN Prospective mortality study. OBJECTIVE To assess the relationship between comorbid medical conditions and other health-related factors to mortality in chronic spinal cord injury (SCI). SETTING Boston, MA, USA. METHODS Between 1994 and 2000, 361 males >/=1 year after injury completed a respiratory health questionnaire and underwent pulmonary function testing. Cause-specific mortality was assessed over a median of 55.6 months (range 0.33-74.4 months) through 12/31/2000 using the National Death Index. RESULTS At entry, mean (+/-SD) age was 50.6+/-15.0 years (range 23-87) and years since injury was 17.5+/-12.8 years (range 1.0-56.5). Mortality was elevated (observed/expected deaths=37/25.1; SMR=1.47; 95% CI=1.04-2.03) compared to US rates. Risk factors for death were diabetes (RR=2.62; 95% CI=1.19-5.77), heart disease (RR=3.66; 95% CI=1.77-7.78), reduced pulmonary function, and smoking. The most common underlying and contributing causes of death were diseases of the circulatory system (ICD-9 390-459) in 40%, and of the respiratory system in 24% (ICD-9 460-519). CONCLUSIONS These results suggest that much of the excess mortality in chronic SCI is related to potentially treatable factors. Recognition and treatment of cardiovascular disease, diabetes, and lung disease, together with smoking cessation may substantially reduce mortality in chronic SCI.

Abstract
Benign metastasizing leiomyoma is a rare clinical entity that has been described in several previous reports. Although the exact pathophysiology of the disease is unknown, two predominant theories exist: (1) metastasis from an existing leiomyoma (commonly seen with uterine leiomyoma) or (2) multicentric leiomyomatous growths rather than actual metastases. We present an interesting case in which several elements of the patient's history complicated the differential diagnosis.
