RESUMEN

OBJECTIVES: To highlight the occurrence of premature ovarian insufficiency in pediatric cancer patients and determine which patient characteristics or treatment modalities are associated with ovarian failure and recovery. METHODS: Between August 2011-August 2021, 36 of 2,661 patients with cancer were identified to have subsequent ovarian failure. Data collected included cancer type, diagnosis age, types of chemotherapy, bone marrow transplant or radiation treatment, peak FSH, peak AMH, GnRHa treatment, type of hormone replacement therapy, and if ovarian function recovery occurred. RESULTS: The most common cancer type identified was ALL. The mean age of diagnosis was 8.5±4.3 years and mean age of peak FSH value was 12.6±2.8 years. Most patients (97.2 %) were treated with alkylating agents and 72.2 % received radiation. Most patients (72.2 %) received hormone therapy, and 15.8 % of patients received GnRHa Lupron. Ten patients (27.8 %) had ovarian function recovery. Diagnosis age and treatment type were recovery predictors in multivariate regression modeling. Each year older in age was associated with a 30 % decrease in odds of recovery (OR: 0.7, CI: 0.5-0.95, p=0.035), and alkylating agent treatment without transplant was associated with a 3-fold increase in odds of recovery (OR: 3, CI: 2.7-564, p=0.007). CONCLUSIONS: This retrospective review demonstrates that POI can occur in pediatric cancer survivors, emphasizing the importance of educating patients on potential long-term effects of cancer treatment and importance of routine surveillance. This study confirmed that recovery of ovarian function is possible, especially when diagnosed at a younger age, making continued monitoring essential.

RESUMEN

INTRODUCTION: With increased incorporation of simulation-based methodologies into quality improvement activities, standards for reporting on simulation-specific elements in healthcare improvement research are needed. METHODS: We followed established consensus process methodology to iteratively create simulation-based extensions for SQUIRE 2.0 reporting guidelines. Initial steps involved forming a steering committee, defining the scope, and conducting premeeting activities with an expert panel of simulation and quality improvement researchers. Recommendations from the expert panel were brought to a consensus meeting where existing guidelines were reviewed and recommendations made. Steering Committee members reviewed all recommendations, reconciled differences, and made final recommendations, which were piloted by experienced simulation and quality improvement researchers. RESULTS: Fifteen Steering Committee members, 59 experts in simulation and quality improvement research, and 86 consensus meeting attendees reviewed SQUIRE 2.0 reporting guidelines and ultimately recommended simulation-based reporting guidelines for 22 of the 41 (54%) SQUIRE 2.0 guidelines. Those items for which simulation-based extensions were identified were: Notes to Authors, 1 (Title), 2a (Abstract), 2b (Abstract), 4 (Introduction: Available knowledge), 5 (Introduction: Rationale), 7 and 8a & b (Methods: Context and intervention), 9a (Methods - Study of the intervention), 9b (Methods - Study of the intervention), 10a (Methods - Measures), 10b (Methods-Measures), 10c (Methods-Measures), 11b (Methods- Analysis), 12 (Methods - Ethical considerations), 13a (Results), 13e (Results), 14b (Discussion - Summary), 15a-e (Discussion - Interpretation), 16a (Discussion - Limitations), 16b (Discussion - Limitations), 17c (Discussion - Conclusions), and 17d (Discussion - Conclusions). CONCLUSIONS: We created simulation-based extensions to SQUIRE 2.0 reporting guidelines to improve the quality and standardization of reporting on simulation-specific elements of healthcare improvement research.

RESUMEN

Summary: An 11-year-old girl with past medical history of septic shock and multi-organ failure at age 5 presented to her primary care doctor with concern for pallor of the lips. Laboratory studies demonstrated low free thyroxine (T4) and normal thyroid-stimulating hormone (TSH). A referral to endocrinology was made where the patient was evaluated, and laboratory evaluation was repeated. The patient was asymptomatic and clinically euthyroid with a height consistent with her mid-parental height and was in mid- to late-puberty. The repeated laboratory evaluation demonstrated a pattern suggestive of primary hypothyroidism with low free T4 and an elevated TSH. However, the magnitude of elevation of TSH was less than expected, given the degree of lowering of free T4; therefore, central hypothyroidism was considered. Workup was initiated, and laboratory studies and MRI imaging confirmed an underlying diagnosis of panhypopituitarism in the setting of pituitary stalk interruption syndrome. Learning points: Pituitary stalk interruption syndrome is a rare but important cause of panhypopituitarism. Central hypothyroidism should be suspected in patients with low free thyroxine with an inappropriate degree of elevation of thyroid-stimulating hormone. Workup of central hypothyroidism should include multi-pituitary hormone assessment, and, if evident, MRI imaging should be done. Adrenal insufficiency should be suspected in a hypotensive, critically ill patient who is failing to improve on standard-of-care therapy.

RESUMEN

INTRODUCTION: The management of low-risk febrile infants presents a model population for exploring how implicit racial bias promotes inequitable emergency care for children who belong to racial, ethnic and language minority groups. Although widely used clinical standards guide the clinical care of febrile infants, there remains substantial variability in management strategies. Deviations from recommended care may be informed by the physician's assessment of the family's values, risk tolerance and access to supportive resources. However, in the fast-paced emergency setting, such assessments may be influenced by implicit racial bias. Despite significant research to inform the clinical care of febrile infants, there is a dearth of knowledge regarding health disparities and clinical guideline implementation. The proposed mixed methods approach will (1) quantify the extent of disparities by race, ethnicity and language proficiency and (2) explore the role of implicit bias in physician-patient communication when caring for this population. METHODS AND ANALYSIS: With 42 participating sites from the Pediatric Emergency Medicine Collaborative Research Committee, we will conduct a multicenter, cross-sectional study of low-risk febrile infants treated in the emergency department (ED) and apply multivariable logistic regression to assess the association between (1) race and ethnicity and (2) limited English proficiency with the primary outcome, discharge to home without lumbar puncture or antibiotics. We will concurrently perform an interpretive study using purposive sampling to conduct individual semistructured interviews with (1) minority parents of febrile infants and (2) paediatric ED physicians. We will triangulate or compare perspectives to better elucidate disparities and bias in communication and medical decision-making. ETHICS AND DISSEMINATION: This study has been approved by the University of Florida Institutional Review Board. All participating sites in the multicenter analysis will obtain local institutional review board approval. The results of this study will be presented at academic conferences and in peer-reviewed publications.

RESUMEN

Individuals with limited English proficiency (LEP) are at high risk for adverse outcomes in the US health care system. This is particularly true for patients with LEP seeking care in the emergency department (ED). Although professional language interpretation improves the quality of care for these patients, it remains underused. The dynamic, discontinuous nature of an ED visit poses distinct challenges and opportunities for providing equitable, high-quality care for patients with LEP. Evidence-based best practices for identifying patients with LEP and using professional interpretation are well described but inadequately implemented. There are few examples in the literature of rigorous interventions to improve quality of care and outcomes for patients with LEP. There is an urgent need for high-quality research to improve communication with patients with LEP along the continuum of emergency care in order to achieve equity in outcomes.

RESUMEN

Background Despite thrombectomy having become the standard of care for large-vessel occlusion strokes, acute endovascular management in tandem occlusions, especially of the cervical internal carotid artery lesion, remains uncertain. We aimed to compare efficacy and safety of acute carotid artery stenting to balloon angioplasty alone on treating the cervical lesion in tandem occlusions. Similarly, we aimed to explore those outcomes' associations with technique approaches and use of thrombolysis. Methods and Results We performed a systematic review and meta-analysis to compare functional outcomes (modified Rankin Scale), reperfusion, and symptomatic intracranial hemorrhage and 3-month mortality. We explored the association of first approach (anterograde/retrograde) and use of thrombolysis with those outcomes as well. Two independent reviewers performed the screening, data extraction, and quality assessment. A random-effects model was used for analysis. Thirty-four studies were included in our systematic review and 9 in the meta-analysis. Acute carotid artery stenting was associated with higher odds of modified Rankin Scale score ≤2 (odds ratio [OR], 1.95 [95% CI, 1.24-3.05]) and successful reperfusion (OR, 1.89 [95% CI, 1.26-2.83]), with no differences in mortality or symptomatic intracranial hemorrhage rates. Moreover, a retrograde approach was significantly associated with modified Rankin Scale score ≤2 (OR, 1.72 [95% CI, 1.05-2.83]), and no differences were found on thrombolysis status. Conclusions Carotid artery stenting and a retrograde approach had higher odds of successful reperfusion and good functional outcomes at 3 months than balloon angioplasty and an anterograde approach, respectively, in patients with tandem occlusions. A randomized controlled trial comparing these techniques with structured antithrombotic regimens and safety outcomes will offer definitive guidance in the optimal management of this complex disease.

RESUMEN

INTRODUCTION: To understand the baseline quality of team communication behaviors at our organization, we implemented institution-wide simulation training and measured the performance of safety behaviors of ad hoc teams in emergent situations. METHODS: Clinicians participated in 2 interprofessional video-recorded simulation scenarios, each followed by debriefing. Using a standardized evaluation instrument, 2 reviewers independently evaluated the presence or absence of desired team safety behaviors, including escalating care, sharing a mental model, establishing leadership, thinking out loud, and identifying roles and responsibilities. We also scored the quality of sharing the mental model, closed-loop communication, and overall team performance on a 7-point scale. Discordant reviews were resolved with scoring by an additional reviewer. RESULTS: A total of 1404 clinicians participated in 398 simulation scenarios, resulting in 257 usable videos. Overall, teams exhibited desired behaviors at the following frequencies: escalating care, 85%; sharing mental models, 66%; verbally establishing leadership, 6%; thinking out loud, 87%; and identifying roles and responsibilities, 27%. Across all reviews, the quality of the graded behaviors (of 7 points) was 2.8 for shared mental models, 3.3 for closed-loop communication, and 3.2 for overall team performance. CONCLUSIONS: In a simulation setting with ad hoc teams, there was variable performance on completing safety behaviors and only a fair quality of graded communication behaviors. These results establish a baseline assessment of communication and teamwork behaviors and will guide future quality improvement interventions.

RESUMEN

BACKGROUND: Over 5.8 million pediatric visits to rural emergency department (EDs) occur each year in the United States. Most rural EDs care for less than five pediatric patients per day and are not well prepared for pediatrics. Simulation has been associated with improvements in pediatric preparedness. The implementation of pediatric simulation in rural settings is challenging due to limited access to equipment and pediatric specialists. Telesimulation involves a remote facilitator interacting with onsite learners. This article aims to describe the implementation experiences and participant feedback of a 1-year remotely facilitated pediatric emergency telesimulation program in three critical-access hospitals. METHODS: Three hospitals were recruited to participate with a nurse manager serving as the on-site lead. The managers worked with a study investigator to set up the simulation technology during an in-person pilot testing visit with the off-site facilitators. A curriculum consisting of eight pediatric telesimulations and debriefings was conducted over a 12-month period. Participant feedback was collected via a paper survey after each simulation. Implementation metrics were collected after each session including technical and logistic issues. RESULTS: Of 147 participant feedback surveys 90% reported that pediatric simulations should be conducted on a regular basis and overall feedback was positive. Forty-seven of 48 simulations were completed on the first attempt with few major technologic issues. The most common issue encountered related to the simulator not working correctly locally and involved the facilitator running the session without the heart and lung sounds. All debriefings occurred without any issues. CONCLUSIONS: This replicable telesimulation program can be used in the small, rural hospital setting, overcoming time and distance barriers and lending pediatric emergency medicine expertise to the education of critical-access hospital providers.

RESUMEN

Introduction: Using simulation to improve team performance in emergencies is commonplace. Decreasing codes hospital-wide can be challenging. To address these needs, hospital leaders requested a simulation program to provide team training across an institution focused on patient safety and communication techniques. Methods: We developed a multimodal approach pairing three online modules on communication techniques with a simulation-based learning session. The three modules required 1 hour, followed by a 1-hour, in-person, simulation-based, interprofessional, small-group session of clinical staff. In ad hoc teams, participants managed two cases: a toddler with airway obstruction and a child developing septic shock. A focused debriefing included discussion of mental models, team formation and expertise, and communication techniques to create a common language to use in ad hoc team formation and patient care. Results: Through more than 200 training sessions reaching over 1,400 staff members, we executed code response training. A nurse and physician facilitated each session, emphasizing the interprofessional nature needed for patient care. Participants rated the learning experience highly on a 5-point Likert scale (1 = low/poor, 5 = high/excellent), with an average rating of 4.3 for achieving objectives and an average rating of 4.8 for facilitator effectiveness. Discussion: Through engaging leadership and frontline clinicians, the simulation program provided code response training hospital-wide, emphasizing the importance of teamwork and communication in critical situations. Such hospital-wide training can emphasize a shared language to empower clinicians at all levels to deliver safe, quality patient care.

RESUMEN

Safety science in healthcare has historically focused primarily on reducing risk and minimizing harm by learning everything possible from when things go wrong (Safety-I). Safety-II encourages the study of all events, including the routine and mundane, not only bad outcomes. While debriefing and learning from positive events is not uncommon or new to simulation, many common debriefing strategies are more focused on Safety-I. The lack of inclusion of Safety-II misses out on the powerful analysis of everyday work.A debriefing tool highlighting Safety-II concepts was developed through expert consensus and piloting and is offered as a guide to encourage and facilitate inclusion of Safety-II analysis into debriefings. It allows for debriefing expansion from the focus on error analysis and "what went wrong" or "could have gone better" to now also capture valuable discussion of high yield Safety-II concepts such as capacities, adjustments, variation, and adaptation for successful operations in a complex system. Additionally, debriefing inclusive of Safety-II fosters increased debriefing overall by encouraging debriefing when "things go right", not historically what is most commonly debriefed.

RESUMEN

Introduction. Helicobacter suis (Helicobacter heilmannii type 1) commonly infects nonhuman primates but its clinical importance is in question.Aim. To characterize H. suis infection in a colony of rhesus macaques (Macaca mulatta) used in cognitive neuroscience research.Hypothesis/Gap Statement. Inquiries into the nature of Helicobacter suis in nonhuman primates are required to further define the organism's virulence and the experimental animal's gastric microbiome.Methodology. Animals with and without clinical signs of vomiting and abdominal pain (n=5 and n=16, respectively) were evaluated by histology, culture, PCR amplification and sequencing, fluorescent in situ hybridization (FISH) and serology. Three of the five animals with clinical signs, an index case and two others, were evaluated before and after antimicrobial therapy.Results. The index animal had endoscopically visible ulcers and multifocal, moderate, chronic lymphoplasmacytic gastritis with intraglandular and luminal spiral bacteria. Antimicrobial therapy in the index animal achieved histologic improvement, elimination of endoscopically visible ulcers, and evident eradication but clinical signs persisted. In the other treated animals, gastritis scores were not consistently altered, gastric bacteria persisted, but vomiting and abdominal discomfort abated.Nineteen of 21 animals were PCR positive for H. suis and five animals were also PCR positive for H. pylori. Organisms were detected by FISH in 17 of 21 animals: 16S rRNA sequences of two of these were shown to be H. suis. Mild to moderate lymphoplasmacytic gastritis was seen in antrum, body and cardia, with antral gastritis more likely to be moderate than that of the body.Conclusion. No clear association between the bacterial numbers of Helicobacter spp. and the degree of inflammation was observed. H. suis is prevalent in this colony of Macaca mulatta but its clinical importance remains unclear. This study corroborates many of the findings in earlier studies of H. suis infection in macaques but also identifies at least one animal in which gastritis and endoscopically visible gastric ulcers were strongly associated with H. suis infection. In this study, serology was an inadequate biomarker for endoscopic evaluation in diagnosis of H. suis infection.

RESUMEN

BACKGROUND: Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has been associated with a significant risk of thrombotic events in critically ill patients. AIM: To summarize the findings of a multinational observational cohort of patients with SARS-CoV-2 and cerebrovascular disease. METHODS: Retrospective observational cohort of consecutive adults evaluated in the emergency department and/or admitted with coronavirus disease 2019 (COVID-19) across 31 hospitals in four countries (1 February 2020-16 June 2020). The primary outcome was the incidence rate of cerebrovascular events, inclusive of acute ischemic stroke, intracranial hemorrhages (ICH), and cortical vein and/or sinus thrombosis (CVST). RESULTS: Of the 14,483 patients with laboratory-confirmed SARS-CoV-2, 172 were diagnosed with an acute cerebrovascular event (1.13% of cohort; 1130/100,000 patients, 95%CI 970-1320/100,000), 68/171 (40.5%) were female and 96/172 (55.8%) were between the ages 60 and 79 years. Of these, 156 had acute ischemic stroke (1.08%; 1080/100,000 95%CI 920-1260/100,000), 28 ICH (0.19%; 190/100,000 95%CI 130-280/100,000), and 3 with CVST (0.02%; 20/100,000, 95%CI 4-60/100,000). The in-hospital mortality rate for SARS-CoV-2-associated stroke was 38.1% and for ICH 58.3%. After adjusting for clustering by site and age, baseline stroke severity, and all predictors of in-hospital mortality found in univariate regression (p < 0.1: male sex, tobacco use, arrival by emergency medical services, lower platelet and lymphocyte counts, and intracranial occlusion), cryptogenic stroke mechanism (aOR 5.01, 95%CI 1.63-15.44, p < 0.01), older age (aOR 1.78, 95%CI 1.07-2.94, p = 0.03), and lower lymphocyte count on admission (aOR 0.58, 95%CI 0.34-0.98, p = 0.04) were the only independent predictors of mortality among patients with stroke and COVID-19. CONCLUSIONS: COVID-19 is associated with a small but significant risk of clinically relevant cerebrovascular events, particularly ischemic stroke. The mortality rate is high for COVID-19-associated cerebrovascular complications; therefore, aggressive monitoring and early intervention should be pursued to mitigate poor outcomes.

RESUMEN

The 2016 Accreditation Council for Graduate Medical Education Clinical Learning Environment Review report identified knowledge gaps for quality in the clinical environment. It suggested quality improvement (QI) training is necessary to develop skills to improve health care quality. However, at the authors' institution, there is limited department-level QI mentorship and engagement, thus limiting QI experiences for residents and fellows. The authors developed pediatric graduate medical education program director (PD) proficiency in QI through a fellowship-focused QI project. PDs underwent an 18-month QI curriculum consisting of focused online QI education, a half-day workshop, additional QI didactic sessions, project presentations, and individual QI coaching. QI knowledge in 9 domains and participants' confidence were assessed. Participants' self-perceived confidence and skills increased by at least 20% in most domains. Overall, PDs felt prepared to help with their fellows' future QI projects. Fellowship-focused QI projects and individual coaching were key to course engagement.

RESUMEN

BACKGROUND: While mechanical thrombectomy (MT) is the standard of care for large vessel occlusion strokes, the optimal management of tandem occlusions (TO) remains uncertain. We aimed to determine the current practice patterns among stroke physicians involved in the treatment of TO during MT. METHODS: We distributed an online survey to neurovascular practitioners (stroke neurologists, neurointerventionalists, neurosurgeons, and radiologists), members of professional societies. After 2 months the site was closed and data were extracted and analyzed. We divided respondents into acute stenting and delayed treatment groups and responses were compared between the two groups. RESULTS: We received 220 responses from North America (48%), Latin America (28%), Asia (15%), Europe (5%), and Africa (4%). Preferred timing for cervical revascularization varied among respondents; 51% preferred treatment in a subsequent procedure during the same hospitalization whereas 39% preferred to treat during MT. Angioplasty and stenting (41%) was the preferred technique, followed by balloon angioplasty and local aspiration (38%). The risk of intracerebral hemorrhage was the most compelling reason for not stenting acutely (68%). There were no significant differences among practice characteristics and timing groups. Most practitioners (70%) agreed that there is equipoise regarding the optimal endovascular treatment of cervical lesions in TO; hence, 77% would participate in a randomized controlled trial. CONCLUSIONS: The PICASSO survey demonstrates multiple areas of uncertainty regarding the medical and endovascular management of TOs. Experts acknowledged the need for further evidence and their willingness to participate in a randomized controlled trial to evaluate the best treatment for the cervical TO lesion.

RESUMEN

Zebra finches (Taeniopygia guttata) are laboratory animal species commonly used for modeling neurobiology and learning. Historically, using bacterial culture, biochemical analysis, and 16S ribosomal RNA gene sequencing, bacterial isolates from feces of finches housed at Massachusetts Institute of Technology had been presumptively diagnosed as Campylobacter jejuni, which is commonly isolated from both domestic and wild birds. Although the zebra finches were not clinically affected, C. jejuni is a known zoonotic pathogen that causes gastroenteritis in humans worldwide. Human transmission is predominantly foodborne and associated with the consumption of contaminated poultry; however, humans can also become infected from contact with C. jejuni-infected reservoir hosts. Because C. jejuni-infected finches pose a risk to research personnel, a study was undertaken to investigate the prevalence and taxonomic identification of Campylobacter spp. present in the finch colony. Campylobacter spp. were isolated from a total of 26 finch fecal samples collected in 2003, 2010, and 2017. 16S ribosomal RNA sequencing of all isolates determined that they shared 99% identity with either C. jejuni or Campylobacter lari. Sixteen of the isolates were subjected to further biochemical characterization and atpA and rpoB gene sequence analysis. Based on these analyses, three clusters of Campylobacter species were identified. The draft whole-genome sequences were determined for one representative isolate from each cluster. A pan-genomic phylogenetic tree, average nucleotide identity, digital DNA-DNA hybridization, and orthologous gene analyses indicated that each isolate was its own novel species, distinct from C. jejuni and other avian Campylobacter species. We have named these novel species Campylobacter taeniopygiae, Campylobacter aviculae, and Campylobacter estrildidarum, and in each novel species, we identified virulence genes suggesting their pathogenic and zoonotic potential.

RESUMEN

Tricyclic antidepressants (TCAs) were originally designed and marketed for treating depression, but over time they have been applied to a variety of conditions, mostly off-label. TCAs can serve as first-line or augmenting drugs for neuropathic pain, headache, migraine, gastrointestinal syndromes, fibromyalgia, pelvic pain, insomnia, and psychiatric conditions other than depression. This article reviews pharmacology, dosing, and safety considerations for these uses.

RESUMEN

Meloxicam is the most frequently used NSAID in birds; however, its elimination t1/2 is highly variable among species. Because zebra finches that require analgesia could benefit from receiving meloxicam, we performed a pharmacokinetic study involving a single intramuscular dose of 1 or 2 mg/kg. Data analysis showed that Cmax, t1/2, and elimination rate constants were not significantly different between the 2 doses. In contrast, Cmax for 1- and 2-mg/kg doses of meloxicam approached a significant difference, and those for AUC0-∞ were significantly different. Importantly, a plasma concentration of 3500 ng/mL, considered a target level for meloxicam in other avian species, was maintained for approximately 9.5 h in finches that received 2 mg/kg, which was 4 h longer than in birds given 1 mg/kg. Both doses reached low plasma concentrations by 12 h after administration. Subsequently, 8 total doses of 1 or 2 mg/kg were administered to birds at 12-h intervals; these regimens caused no significant changes in select biochemical analytes or the Hct of meloxicam-treated birds. In addition, histopathologic changes for injection sites, kidney, liver, proventriculus, and ventriculus were minimal and similar between control and experimental groups after the multiple doses. These results suggest a 12-h or more frequent dosing interval is likely needed in zebra finches and that meloxicam at 1 or 2 mg/kg IM twice daily for 4 d is safe. The higher dose might provide longer analgesia compared with the lower dose, but a pharmacodynamics evaluation of meloxicam in zebra finches is needed to confirm analgesic efficacy.

Background and Purpose: To describe the final results of the TARGET Registry, a multicenter, real-world study of patients with intracranial aneurysms treated with new generation TARGET Coils. Methods: The TARGET Registry is a prospective, single-arm study with independent medical event monitoring and core-lab adjudication. Patients with de novo intracranial aneurysms were embolized with either TARGET-360° or helical coils in 12 US centers. The primary outcome was aneurysm packing density (PD), which was assessed immediately post-procedure. The secondary outcomes were immediate and long-term aneurysm occlusion rate using the Raymond Scale, and independent functional outcome using the modified Rankin Scale (mRS). A secondary analysis investigated the influence of the use of 100% 360-complex coils on clinical and angiographic outcomes. Results: 148 patients with 157 aneurysms met the inclusion and exclusion criteria. 58 (39.2%) patients with ruptured and 90 (61.8%) with unruptured aneurysms were treated using TARGET 360°, helical Coils, or both. Median age was 58.3 (IQR 48.1-67.4), 73% female, and 71.6% were Caucasian. Median follow-up time was 5.9 (IQR 4.0-6.9) months. The majority were treated with TARGET 360-coils (63.7%), followed by mixed and helical coils only. Peri-procedural morbidity and mortality was seen in 2.7% of patients. A good outcome at discharge (mRS 0-2) was seen in 89.9% of the full cohort, and in 84.5 and 93.3% in the ruptured and unruptured patients, respectively. The median packing density was 28.8% (IQR 20.3-41.1). Long-term complete and near complete occlusion rate was seen in 90.4% of aneurysms and complete obliteration was seen in 66.2% of the aneurysms. No significant difference in clinical and angiographic outcomes were noted between the pure 360-complex coiling vs. mixed 360-complex/Helical coiling strategies. In a multivariate analysis, predictors for long-term aneurysm occlusion were aneurysm location, immediate occlusion grade, and aneurysm size. The long-term independent functional outcome was achieved in 128/135 (94.8%) patients and all-cause mortality was seen in 3/148 (2%) patients. Conclusion: In the multicenter TARGET Registry, two-thirds of aneurysms achieved long-term complete occlusion and 91.0% achieved complete or near complete occlusion with excellent independent functional outcome.

RESUMEN

BACKGROUND: Increasing amounts of diabetes-focused content is being posted to YouTube with little regulation as to the quality of the content. Diabetic education has been shown to reduce the risk of ulceration and amputation. YouTube is a frequently visited site for instructional and demonstrational videos posted by individuals, advertisers, companies, and health-care organizations. We sought to evaluate the usefulness of diabetic foot care video information on YouTube. METHODS: YouTube was queried using the keyword phrase diabetic foot care. Original videos in English, with audio, less than 10 min long within the first 100 video results were evaluated. Two reviewers classified each video as useful or nonuseful/misleading. A 14-point usefulness criteria checklist was used to further categorize videos as most useful, somewhat useful, or nonuseful/misleading. Video sources were categorized by user type, and additional video metrics were collected. RESULTS: Of 87 included videos, 56 (64.4%), were classified as useful and 31 (35.6%) as nonuseful/misleading. A significant difference in the mean length of useful videos vs nonuseful/misleading videos was observed (3.33 versus 1.73 min; P < .0001). There was no significant difference in terms of popularity metrics (likes, views, subscriptions, etc) between useful and nonuseful/misleading videos. CONCLUSIONS: This study demonstrates that although most diabetic foot care videos on YouTube are useful, many are still nonuseful/misleading. More concerning is the lack of difference in popularity between useful and nonuseful videos. Podiatric physicians should alert patients to possibly misleading information and offer a curated list of videos.
