Project description:Neurointerventional education relies on an apprenticeship model, with the trainee observing and participating in procedures with the guidance of a mentor. While educational videos are becoming prevalent in surgical cases, there is a dearth of comparable educational material for trainees in neurointerventional programs. We sought to create a high-quality, three-dimensional video of a routine diagnostic cerebral angiogram for use as an educational tool. A diagnostic cerebral angiogram was recorded using two GoPro HERO 3+ cameras with the Dual HERO System to capture the proceduralist's hands during the case. This video was edited with recordings from the video monitors to create a real-time three-dimensional video of both the actions of the neurointerventionalist and the resulting wire/catheter movements. The final edited video, in either two or three dimensions, can serve as another instructional tool for the training of residents and/or fellows. Additional videos can be created in a similar fashion of more complicated neurointerventional cases. The GoPro HERO 3+ camera and Dual HERO System can be used to create educational videos of neurointerventional procedures.

Project description:ObjectivesTo investigate the change in rate of invasive procedures (endotracheal intubation, central venous catheters, arterial catheters, and peripheral inserted central venous catheters) performed in PICUs per admission over time. Secondarily, to investigate the change in type of respiratory support over time.DesignRetrospective study of prospectively collected data using the Virtual Pediatric Systems (VPS; LLC, Los Angeles, CA) database.SettingNorth American PICUs.PatientsPatients admitted from January 2009 to December 2017.InterventionsNone.Measurements and main resultsThere were 902,624 admissions from 161 PICUs included in the analysis. Since 2009, there has been a decrease in rate of endotracheal intubations, central venous catheters placed, and arterial catheters placed and an increase in the rate of peripheral inserted central venous catheter insertion per admission over time after controlling for severity of illness and unit level effects. As compared to 2009, the incident rate ratio for 2017 for endotracheal intubation was 0.90 (95% CI, 0.83-0.98; p = 0.017), for central venous line placement 0.69 (0.63-0.74; p < 0.001), for arterial catheter insertion 0.85 (0.79-0.92; p < 0.001), and for peripheral inserted central venous catheter placement 1.14 (1.03-1.26; p = 0.013). Over this time period, in a subgroup with available data, there was a decrease in the rate of invasive mechanical ventilation and an increase in the rate of noninvasive respiratory support (bilevel positive airway pressure/continuous positive airway pressure and high-flow nasal oxygen) per admission.ConclusionsOver 9 years across multiple North American PICUs, the rate of endotracheal intubations, central catheter, and arterial catheter insertions per admission has decreased. The use of invasive mechanical ventilation has decreased with an increase in noninvasive respiratory support. These data support efforts to improve exposure to invasive procedures in training and structured systems to evaluate continued competency.

Project description:ObjectiveThis paper examines the development and evaluation of an automatic summarization system in the domain of molecular genetics. The system is a potential component of an advanced biomedical information management application called Semantic MEDLINE and could assist librarians in developing secondary databases of genetic information extracted from the primary literature.MethodsAn existing summarization system was modified for identifying biomedical text relevant to the genetic etiology of disease. The summarization system was evaluated on the task of identifying data describing genes associated with bladder cancer in MEDLINE citations. A gold standard was produced using records from Genetics Home Reference and Online Mendelian Inheritance in Man. Genes in text found by the system were compared to the gold standard. Recall, precision, and F-measure were calculated.ResultsThe system achieved recall of 46%, and precision of 88% (F-measure=0.61) by taking Gene References into Function (GeneRIFs) into account.ConclusionThe new summarization schema for genetic etiology has potential as a component in Semantic MEDLINE to support the work of data curators.

Project description:Anesthesiology residents spend most of their training in operating rooms, but intraoperative teaching is often unstructured. Needs assessment indicated a need to incorporate a more evidence-based approach to education and improvement of our methods of introducing residents to primary anesthesiology literature. Kern's 6-step approach to curriculum development was used to create a robust and innovative curriculum to increase both the evidence-based component of our curriculum and the amount of educational intraoperative discussion among trainees and faculty. Our curriculum uses a structured topic outline, an e-journal club, and other relevant resources to facilitate discussion of the topics.

Project description:ObjectiveTo compare risk of reintervention, long-term clinical outcomes, and health care utilization among women who have bulk symptoms from leiomyoma and who underwent the following procedures: hysterectomy, myomectomy, uterine artery embolization, and magnetic resonance-guided, focused ultrasound surgery.MethodsThis was a retrospective analysis of administrative claims from a large U.S. commercial insurance database. Women aged 18-54 years undergoing any of the previously mentioned leiomyoma procedures between 2000 and 2013 were included. We assessed the following outcome measures: risk of reintervention between uterine-sparing procedures, risk of other surgical procedures or complications of the index procedure, 5-year health care utilization, pregnancy rates, and reproductive outcomes. Propensity score matching along with Cox proportional hazard models were used to adjust for differences in baseline characteristics between study cohorts.ResultsAmong the 135,522 study-eligible women with mean follow-up of 3.4 years, hysterectomy was the most common first-line procedural therapy (111,324 [82.2%]) followed by myomectomy (19,965 [14.7%]), uterine artery embolization (4,186 [3.1%]) and magnetic resonance-guided focused ultrasound surgery (47 [0.0003%]). Small but statistically significant differences were noted for uterine artery embolization and myomectomy in reintervention rate (17.1% compared with 15.0%, P=.02), subsequent hysterectomy rates (13.2% compared with 11.1%, P<.01) and subsequent complications from index procedures (18.1% compared with 24.6%, P<.001). During follow-up, women undergoing myomectomy had lower leiomyoma-related health care utilization, but had higher all-cause outpatient services. Pregnancy rates were 7.5% and 2.2% among myomectomy and uterine artery embolization cohorts, respectively (P<.001) with both cohorts having similar rates of adverse reproductive outcome (69.4%).ConclusionsAlthough the overwhelming majority of women having leiomyoma with bulk symptoms underwent hysterectomy as their first treatment procedure, among those undergoing uterine-sparing index procedures, approximately one seventh had a reintervention, and one tenth ended up undergoing hysterectomy during follow-up. Compared with women undergoing myomectomy, women undergoing uterine artery embolization had a higher risk of reintervention, lower risk of subsequent complications, but similar rate of adverse reproductive outcomes.

Project description:IntroductionThe last 10-15 years has seen a decline in formal undergraduate urological education throughout Canada. Given the large volume of urological presentations in family practice, trainees need to acquire the requisite urological knowledge and skills to serve their patients. The objective of this study is to determine the perceived level of urological knowledge and skills among Canadian family medicine residents.MethodsA 15-item, anonymous, online survey was distributed via email to all Canadian family medicine program directors from September to December 2018 and distributed to their residents. The survey obtained data on demographics, training, undergraduate urology experience, self-reported proficiency in interpreting urological investigations, performing common urological procedures, and managing common urological conditions. Descriptive statistics were used to summarize data.ResultsThe questionnaire was completed by 142 family medicine residents with representation from Western Canada (27.5%), Ontario (32.4%), and Quebec (40.1%); 39.4% of respondents had completed a urology rotation during medical school and only 29.1% felt that their medical training prepared them for the urological aspects of family medicine. Although the majority of respondents felt proficient in performing a digital rectal examination (58.5%) or managing urinary tract infections (97.9%), only a minority felt competent in performing male genitourinary examination (40.1%), uncomplicated male (34.5%), female (45.8%) or difficult (9.2%) urethral catheterization. Likewise, the minority of respondents felt comfortable managing erectile dysfunction (41.5%), scrotal swelling (34.7%), and scrotal pain (25.7%).ConclusionsThere are significant deficiencies in urological knowledge and skills among family medicine residents in Canada, possibly because of insufficient educational experiences during medical training.

Project description:We previously described BCL::Conf, a knowledge-based conformation sampling algorithm utilizing a small molecule fragment rotamer library derived from the Cambridge Structural Database (CSD, license required), as a component of the BioChemical Library (BCL) cheminformatics toolkit. This paper describes substantial improvements made to the BCL::Conf algorithm and a transition to a rotamer library derived from molecules in the Crystallography Open Database (COD, no license required). We demonstrate the performance of the new BCL::Conf on native conformer recovery in the Platinum dataset of high-quality protein-ligand complexes. This set of 2859 structures has previously been used to assess the performance of over a dozen conformer generation algorithms, including the Conformator, Balloon, RDKit DG, ETKDG, Confab, Frog2, MultiConf-DOCK, CSD conformer generator, ConfGenX-OPSL3 force field, Omega, excalc, iCon, and MOE. These benchmarks suggest that the CSD conformer generator is at the state of the art of reported conformer generators. Our results indicate that the improved BCL::Conf significantly outperforms the CSD conformer generation algorithm at binding conformer recovery across a range of ensemble sizes and with similarly fast rates of conformer generation. BCL::Conf is now distributed with the COD-derived rotamer library and is free for academic use. The BCL can be downloaded at http://meilerlab.org/bclcommons for Windows, Linux, or Apple operating systems. BCL::Conf can now also be accessed via webserver at http://meilerlab.org/bclconf.

Project description:BackgroundThe reporting of post-operative complications in the urological field is lacking of a uniform quantitative measure to assess severity, which is essential in the analysis of surgical outcomes. The purpose of this study was to evaluate the feasibility of estimating quantitative severity weighing of post-operative complications after common urologic procedures.MethodsUsing a large healthcare system's quality database, complications were identified in eleven common urologic procedures (e.g., insertion or replacement of inflatable penile prosthesis, nephroureterectomy, partial nephrectomy, percutaneous nephrostomy tube placement, radical cystectomy, radical prostatectomy, renal/ureteral/bladder extracorporeal shockwave lithotripsy (ESWL), transurethral destruction of bladder lesion, transurethral prostatectomy, transurethral removal of ureteral obstruction, and ureteral catheterization) from January 1, 2011 to December 31, 2011. Complications were classified by the Expanded Accordion Severity Grading System, which was then quantified by validated severity weighting scores. The Postoperative Morbidity Index (PMI) for each procedure was calculated where an index of 0 would indicate no complication in any patient and an index of 1 would indicate that all patients died.ResultsThis study included 654 procedures of which 148 (22%) had one or more complications. As would be expected, a more complex procedure like radical cystectomy possessed a higher PMI (0.267), while a simpler procedure like percutaneous nephrostomy tube placement possessed a lower PMI (0.011). The PMI of the additional nine procedures fell within the range of these PMIs. These PMIs could be used to compare surgeons, hospitals or procedures.ConclusionsQuantitative severity weighing of post-operative complications for urologic procedures is feasible and may provide exceptionally informative data related to outcomes.

Project description:ObjectiveTo investigate the changes in elective private urological procedures in Australia during the coronavirus disease 2019 pandemic.MethodsData were extracted from publicly available datasets from Medicare Benefits Schedule using item numbers assigned to each commonly performed urological intervention. These procedures were divided into three groups: Oncological therapeutic, diagnostic, and non-oncological therapeutic procedures. A smoothing model, based on the historic procedure numbers from 2017 to 2019, was used to forecast monthly number of procedures performed in each category between January 2020 and June 2020. These forecasted models were compared with reported figures.ResultsA total of 108 169 procedures were performed between January 2020 and June 2020 based on the Medicare Benefits Schedule item numbers listed. There was a significant reduction (percentage change) in total procedures performed in April 2020 (-22.6%, 95% confidence interval [CI]: -28.7% to -15.4%) and May 2020 (-33.2%, 95% CI: -37.5% to -28.3%). There was a significant reduction in oncological therapeutic, non-oncological therapeutic, and diagnostic procedures performed in April 2020 and May 2020 (p<0.05). These numbers did not include procedures performed in public sector.ConclusionThere was a significant reduction in total urological procedures (including diagnostic, oncological, and non-oncological) performed in months of April 2020 and May 2020 during time of federal restrictions. Both public and private healthcare sectors need to be supported in the upcoming months to prevent further delays in treatment and poorer clinical outcomes.
