Using Learning Analytics to Evaluate the Clinical Education Podcast Format.

Learning analytics has been rigorously applied to various forms of e-learning, but not to the evaluation of clinical education podcasts. We created a podcast series using the Anchor by Spotify platform, uploading an episode every 2 weeks starting on March 30, 2021. We examined analytics data using a censoring date of November 1, 2022. Based on 29,747 total plays, average audience retention declined 10%/minute until an inflection point at 2.5 minutes, followed by a steady decline of 1.8%/minute. With a maximum episode length of 17 minutes, we did not identify a limit on learner attention for short-form podcasts.

Podcast-Based Medical Education and Content Alignment with National Education Bodies.

Introduction: Despite the rapid expansion of medical education podcasts in the past decade, there are few efforts to characterize the landscape of available content for specific medical specialties. We trialed a method of rigorous characterization for the field of neurology. Materials and Methods: Using a censoring date of July 25, 2022, we queried the top three podcast platforms for neurology education podcasts: Apple Podcasts, Spotify, and Google Podcasts. We characterized podcasts based on total number of episodes, episode release frequency, target audience, and affiliation type. We characterized individual episodes by length and primary content area as defined by the Accreditation Council for Graduate Medical Education (ACGME) and American Board of Psychiatry and Neurology (ABPN). We compared content availability with content recommendations from these education bodies. Results: We identified 30 podcasts sharing 1772 episodes and totaling 46,287 min. The ACGME subspecialties most frequently covered were vascular neurology (5082 total min, 11%), neuroimmunology (4,406, 10%), and neuromuscular diseases (3,771, 8%). Subjects that were underrepresented included palliative neurology (89 min, 0.2%), neuropathology (95 min, 0.2%), and bioethics (171 min, 0.4%). The coverage of ABPN examination topics varied substantially from the content distribution for the examination. Discussion: The current landscape of neurology education podcasts features heterogeneous coverage of topics and varies considerably from recommended distribution of content by national education bodies. As podcasts have tremendous potential in supplementing neurology education, characterizing available content may help various stakeholders in the neurology education pipeline optimize the use of this e-learning modality.

Dural arteriovenous fistula of the craniocervical junction.

Dural arteriovenous (AV) fistulas of the craniocervical junction can be challenging to diagnose. We describe a 70-year-old man with subacute progressive myelopathy whose MR scan of cervical spine showed serpiginous dorsal vessels, suggesting a dural AV fistula. However, a detailed diagnostic angiogram was normal, prompting additional work-up and a wider differential, which was non-revealing. His symptoms progressed over months, but the evolution of the lesion characteristics on repeat spinal imaging still suggested a dural AV fistula. Repeat angiogram identified an infratentorial dural AV fistula arising from the meningohypophyseal artery. He improved following retrosigmoid craniotomy and clipping. Initial angiography does not always demonstrate a dural AV fistula; if there is clinical and radiographic evolution, repeat angiography might identify a fistula with a rare arterial feeder.

Dry Eye Syndrome and Sicca Complex are Commonly Found in Patients with Postural Orthostatic Tachycardia Syndrome.

PURPOSE: Patients with postural orthostatic tachycardia syndrome (POTS) present to outpatient dysautonomia clinics endorsing a wide range of symptoms. Dry eyes and mouth, or sicca complex are frequently reported. This retrospective study investigates the incidence and quantifies the severity of dry eye syndrome (DES) in patients with POTS. PATIENTS AND METHODS: This retrospective study compiles survey results, and dry eye clinical data from twenty-three POTS patients (22 females, average age 34.9 and st dev 14.0 years) surveyed during their initial or follow-up appointments. Patient's medication lists were documented to account for anticholinergics, antihistamines, and anticholinesterase use. Patients endorsing dry eye symptoms were tested with Schirmer's test strips to identify clinically dry eyes and stratified for severity. RESULTS: Sixty-five percent of patients endorsed dry eye symptoms (15/23). Seventy-four percent of patients endorsed dry mouth symptoms (17/23). Among patients endorsing dry eyes, 81% of eyes had decreased tear production with Schirmer's strip wetting less than 10 mm/5 min (13/16). CONCLUSION: DES is an additional and significant disease burden for the POTS patient population. Dry eye and exocrine gland function should be evaluated as part of the dysautonomia work up with referral to ophthalmology as appropriate. Patients with clinically dry eyes who report additional autonomic dysfunction should be further evaluated for widespread autonomic dysfunction.

Intravenous Hyaluronidase with Urokinase as Treatment for Rabbit Retinal Artery Hyaluronic Acid Embolism.

BACKGROUND: Although various salvage methods have been proposed to treat intraretinal artery hyaluronic acid embolism, their applications are still limited by various factors. The authors investigated the effectiveness of intravenous hyaluronidase with urokinase for resolving retinal artery hyaluronic acid embolism. METHODS: The anatomy of rabbit ophthalmic and fundus arteries (retinal and choroid artery) was studied. Approximately 0.35 ml of hyaluronic acid was injected into the ophthalmic artery to create a retinal artery embolism model. The rabbits were grouped randomly (groups A, B, C, D, E, and F) and given hyaluronidase with urokinase intravenously at different postobstruction time points (10, 20, 30, 40, 50, and 60 minutes). Saline was given to the control group. Fundus vascular (retinal and choroid artery) reperfusion status and the effectiveness of the solution on the obstruction of each group were observed for 5 days. RESULTS: The animal model closely imitated actual hyaluronic acid ophthalmic/retinal artery obstructions. Three vascular conditions were observed after hyaluronidase with urokinase injection: total, partial, and no reperfusion. Groups A, B, and C showed a significantly higher overall solution effectiveness rate (total/partial reperfusion) compared with the control group (p = 0.001, p = 0.001, and p = 0.005, respectively). Solution effectiveness in groups D, E, and F showed no difference compared with the control group (p = 0.628, p = 1.000, and p = 1.000, respectively). The effectiveness of the solution drops dramatically if given after 30 minutes of obstruction. CONCLUSIONS: The authors' method can indeed help resolve retinal artery hyaluronic acid obstruction. Intravenous hyaluronidase with urokinase technique shows possible potential to become a standardized treatment protocol for intraretinal artery hyaluronic acid embolism with further clinical tests.

Effects of feminizing reconstructive surgery on sexual function and genital sensitivity in patients with female pseudohermaphroditism versus healthy control.

OBJECTIVE: To investigate the effect on sexual function and genital sensitivity of adult female pseudohermaphroditism patients received feminizing reconstructive surgical treatment. MATERIALS AND METHODS: A total of 32 female pseudohermaphroditism patients and 10 healthy women were in enrolled in this study. All patients underwent feminizing reconstructive surgical procedures in adulthood. Sensitivity thresholds for clitoris and upper vagina were tested using a Genito Sensory Analyzer, and sexual function was assessed using a standardized measure simultaneously. RESULTS: In those patients who underwent surgical procedures, there was a mild impairment to sensitivity in the clitoris compared to healthy controls. The sensitivity thresholds in the upper vagina also did not differ significantly between the two groups. No significant difference of sexual function was observed on these adult female pseudohermaphroditism patients compared to those healthy controls. CONCLUSIONS: Surgery may lead to mild decreased sensitivity of clitoris, but did not cause sexual dysfunction in adult female pseudohermaphroditism patients.

Time for change: a roadmap to guide the implementation of the World Anti-Doping Code 2015.

A medical and scientific multidisciplinary consensus meeting was held from 29 to 30 November 2013 on Anti-Doping in Sport at the Home of FIFA in Zurich, Switzerland, to create a roadmap for the implementation of the 2015 World Anti-Doping Code. The consensus statement and accompanying papers set out the priorities for the antidoping community in research, science and medicine. The participants achieved consensus on a strategy for the implementation of the 2015 World Anti-Doping Code. Key components of this strategy include: (1) sport-specific risk assessment, (2) prevalence measurement, (3) sport-specific test distribution plans, (4) storage and reanalysis, (5) analytical challenges, (6) forensic intelligence, (7) psychological approach to optimise the most deterrent effect, (8) the Athlete Biological Passport (ABP) and confounding factors, (9) data management system (Anti-Doping Administration & Management System (ADAMS), (10) education, (11) research needs and necessary advances, (12) inadvertent doping and (13) management and ethics: biological data. True implementation of the 2015 World Anti-Doping Code will depend largely on the ability to align thinking around these core concepts and strategies. FIFA, jointly with all other engaged International Federations of sports (Ifs), the International Olympic Committee (IOC) and World Anti-Doping Agency (WADA), are ideally placed to lead transformational change with the unwavering support of the wider antidoping community. The outcome of the consensus meeting was the creation of the ad hoc Working Group charged with the responsibility of moving this agenda forward.
