RESUMO

RATIONALE AND OBJECTIVES: The purpose of this study is to investigate the variance of women authors, specifically first and senior authorship among peer-reviewed artificial intelligence-related articles with a specific focus in breast imaging. MATERIALS AND METHODS: A strategic search was conducted in July 2022 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to capture all existing and publicly available peer-reviewed articles intersecting AI and breast imaging. Primary outcomes were first and senior authors' gender, which were assigned with the aid of an emailed self-declaration survey. Secondary outcomes included country of article, journal impact factor, and year of publication. Comparisons were made using logistic regression models and analysis of variances. RESULTS: 115 studies were included in the analysis. Women authors represented 35.7% (41/115) and 37.4% (43/115) of first and senior authors, respectively. Logistic regression modelling showed a significant increase in women senior authors over time but no changes in women first authors. Impact factor was not associated with female authorship and certain countries had women authorship reach over 50%. CONCLUSION: This study demonstrates that there is a significant authorship gender gap in artificial intelligence breast imaging research. An increasing temporal trend of senior authors in breast imaging AI-related research is a promising prognosis for more women voices in this field. Further study needs to be done to understand the reasons behind this gap and any potential implications.

RESUMO

BACKGROUND: This study's objective is to evaluate the emotional experiences, coping mechanisms, and support resources for Canadian vascular surgeons and trainees following an adverse patient event or near miss. METHODS: This is a cross-sectional survey study of all Canadian Society for Vascular Surgery (CSVS) members from October to November 2021. We collected data on participant experiences with adverse events, their emotional responses, the coping mechanisms used, and their perceptions on available support resources. RESULTS: The survey was sent to 233 CSVS members yielding 66 responses. The majority (77%) of respondents had experiences with adverse event causing serious patient harm. The most common negative experience following an adverse event included feelings of negativity towards oneself, general distress, and anxiety about potential for future errors. The most common coping mechanism was seeking advice from a mentor or close colleague. Peers (82%) and senior colleagues (59%) were the most preferred sources of support. Most of the respondents would reach out to a mentor if they had 1, but 30% reported no mentor or close colleague for support. CONCLUSION: Adverse patient events and near misses have serious negative impact on the lives of Canadian vascular surgeons and trainees. Peers and senior colleagues are the most desired source for support, but this is not universally available. Organized efforts are needed to bring awareness in our vascular surgery community on the ubiquitous nature and detrimental effects of adverse events.

RESUMO

PURPOSE: Despite nearly a quarter of Canadians and Americans reported to be living with a disability, persons with disabilities continue to face both physical and cultural barriers with respect to careers in medicine. Equity, diversity, and inclusion (EDI) statements can act as a first step in deconstruction of these cultural barriers. However, when compared to other EDI initiatives focused on gender, race, and ethnicity, persons with disabilities receive little attention. METHODS: We conducted a cross-sectional analysis of all radiology residency program websites in Canada and the United States (US). Data was collected from each radiology department website including the presence or absence of an EDI statement or page; if present, we determined whether mention was made of persons with disabilities. RESULTS: We reviewed the websites of 16 Canadian and 181 US radiology residency programs. Seven (44%) Canadian institutions had an EDI statement, with one (14%) mentioning persons with disabilities. In the US, 103 (57%) institutions had an EDI statement, with 42 (41%) mentioning persons with disabilities. CONCLUSIONS: There were a significant proportion of radiology residency programs without EDI statements on their websites and an even smaller proportion that acknowledged persons with disabilities. An institution's public commitment to EDI, and specifically to patients and providers with disabilities, is central to implementing inclusive change going forward.

RESUMO

Purpose: To examine trends in female authorship of peer-reviewed North American radiology articles centred around artificial intelligence (AI). Method: A bibliographic search was conducted for all AI-related articles published in four North American radiology journals. Collected data included the genders of the first and last (senior) authors, year and country. We compared the trends of female authorship using Pearson chi-square, Fisher exact tests and logistic regression models. Results: 453 articles met the inclusion criteria. Among these, 107 (22.3%) had a female first author and 97 (27.3%) had a female senior author. Female first authors were over three times more likely to publish with a female senior author. Among the four journals, the CARJ had the highest proportion of female senior authors at 45.5%. The only significant temporal trend identified was an increase over the years in female senior authors in Radiology. Twenty-four countries contributed to the included articles, with the largest contributors being the United States (n = 290) and Canada (n = 30). Of the countries contributing more than 15 articles, there were none with above 50% female authorship. Conclusions: Female authors are underrepresented in AI-related radiology literature. However, there has been an encouraging recent increase in female authorship in AI-related radiology articles trending towards significance. There is a great opportunity to improve female representation in AI with intentional mentorship and recruitment. We urge more platforms for female voices in radiology as AI becomes increasingly integrated into the radiology community.

RESUMO

OBJECTIVE: The primary objective of this study is to describe and illustrate the technique of ultrasound-guided percutaneous proximal axillary artery (PAA) access, and secondarily to evaluate the versatility and safety of this approach in peripheral, visceral, and aortic endovascular interventions. METHODS: This is a single-center retrospective review of all peripheral, visceral, and aortic endovascular cases using percutaneous PAA access from February 2019 to March 2021 compared with a sample of an equivalent number of consecutive cases completed via percutaneous common femoral artery (CFA) access during the same time period. Access entry success, minor and major access site complications within 30 days, major adverse events within 30 days, demographics, and procedural details were analyzed using standard statistical analyses. RESULTS: A total of 115 accesses-59 PAA and 56 CFA-were reviewed during the study period. Group demographics were not significantly different. Access entry success was achieved in 58 (98.3%) and 56 (100%) of PAA and CFA accesses, respectively, with no statistically significant difference. There were no significant differences in minor access-site complications (13.6% vs 5.4%; P = .21) major access site complications (3.4% vs 7.1%; P = .43), or major adverse events (6.8% vs 5.4%). between the PAA and CFA groups. With respect to versatility, PAA cases had a significantly greater mean number of vessels intervened on per procedure compared with CFA access (2.59 ± 1.31 vs 1.95 ± 0.98; P < .01). A wide range of target vessels were intervened on in both groups. PAA cases had significantly more bilateral lower leg interventions (28.8% vs 12.5%; P = .04). PAA access had a significantly longer mean procedure time (103.2 minutes vs 58.63 minutes; P < .001) and fluoroscopy time (18.21 minutes vs 12.87 minutes; P = .02). CONCLUSIONS: The PAA is a feasible, versatile, and safe percutaneous access option for endovascular intervention. The in-line trajectory from this site facilitates visceral, renal, aortic, and bilateral lower extremity interventions with ease. Outcomes, complications, and major adverse events are similar to those of conventional CFA access in the short term.

RESUMO

INTRODUCTION AND IMPORTANCE: Although foreign bodies are a rare cause of gastrointestinal tract perforation, they may serve as a nidus for hepatic abscess. Abdominal pain is the most common presenting symptom. We present a case of an ingested pen causing duodenal perforation and hepatic abscess several months after initially presenting with a pericardial effusion. CASE PRESENTATION: A 59-year-old female living in an intensive tertiary mental health facility was noted to have an incidental pericardial effusion during work-up for hyponatremia. Seven months later, she developed a new fever and was noted to have interval increase in the pericardial effusion size. This prompted further investigation which finally revealed that an ingested pen had perforated through the first part of the duodenum and caused an abscess in the left lobe of the liver. The pericardial effusion was presumed secondary to local inflammation. Upon discovery of the abscess, the patient underwent successful operative management including abscess drainage, foreign body extraction, and duodenal repair. CLINICAL DISCUSSION: Reports of hepatic abscess from foreign body causing duodenal perforation are rare, with bone fragments and toothpicks the most common foreign bodies implicated. There is one other previously reported case of an ingested pen. Abdominal pain is present in up to 85% of cases, but fever may be the only presenting symptom. CONCLUSION: Foreign body migration causing a hepatic abscess may present non-specifically with unexplained fever or even pericardial effusion. Psychiatric comorbidities may contribute to delays in diagnosis due to difficulties recalling the episode of ingestion.

RESUMO

We report a case of a mycotic abdominal aortic aneurysm caused by invasive group B streptococcus. Given the anatomical suitability with healthy segments of aortoiliac vessels, in situ repair was performed. A cryopreserved femoral vein graft was chosen because of risks of graft reinfection and negated the need for bilateral femoral vein harvest. The patient remained clinically well and the graft patent with no concerns at 6 months of follow-up. A review of literature on group B Streptococcus aortitis was performed.

RESUMO

Purpose: Transgender and gender non-binary (TGNB) individuals face numerous inequalities in healthcare and there is substantial work to be done in fostering TGNB culturally competent care in radiology. A radiology department's online presence and use of gender-inclusive language are essential in promoting an environment of equity, diversity, and inclusion (EDI). The naming of radiology fellowships and continuing medical education (CME) courses with terminology such as "Women's Imaging" indicates a lack of inclusivity to TGNB patients and providers, which could result in suboptimal patient care. Methods: We conducted a cross-sectional analysis of all institutions in Canada and the United States (US) offering training in Breast Imaging, Women's Imaging, or Breast and Body Imaging. Data was collected from each institution's radiology department website pertaining to fellowship names, EDI involvement, and CME courses. Results: 8 Canadian and 71 US radiology fellowships were identified. 75% of Canadian and 90% of US fellowships had gender-inclusive names. One (12.5%) Canadian and 29 (41%) US institutions had EDI Committees mentioned on their websites. Among institutions publicly displaying CME courses about breast/body or women's imaging, gender-inclusive names were used in only 1 (25%) of the Canadian CME courses, compared to 81% of the US institutions. Conclusions: Most institutions in Canada and the US have gender-inclusive names for their radiology fellowships pertaining to breast and body imaging. However, there is much opportunity to and arguably the responsibility for institutions in both countries to increase the impact and visibility of their EDI efforts through creation of department-specific committees and CME courses.

RESUMO

We report a case of a hybrid aortic debranching procedure for repair of a paravisceral inflammatory aortic aneurysm. Vein grafts were chosen over prosthetics because of concern for infection as a possible etiology. The gonadal vein was successfully used as a vein graft between the right common iliac artery and the right renal artery before aortic endograft placement.

RESUMO

PURPOSE: This study determined the predictors of caregivers' willingness to accept an accelerated regulatory process for the development of vaccines against coronavirus disease 2019 (COVID-19). METHODS: An international cross-sectional survey was administered to 2557 caregivers of children in 17 pediatric emergency departments (EDs) across 6 countries from March 26, 2020, to June 30, 2020. Caregivers were asked to select 1 of 4 choices with which they most agreed regarding a proposed COVID-19 vaccine-approval process, in addition to questions regarding demographic characteristics, the ED visit, and attitudes about COVID-19. Univariate analyses were conducted using the Mann-Whitney U test for comparing non-normally distributed continuous variables, an independent t test for comparing normally distributed continuous variables, and a χ2 or Fisher exact test for categorical variables. Multivariate logistic regression analysis was used for determining independent factors associated with caregivers' willingness to accept abridged development of a COVID-19 vaccine. A P value of <0.05 was considered significant. FINDINGS: Almost half (1101/2557; 43%) of caregivers reported that they were willing to accept less rigorous testing and postresearch approval of a new COVID-19 vaccine. Independent factors associated with caregivers' willingness to accept expedited COVID-19 vaccine research included having children who were up to date on the vaccination schedule (odds ratio [OR] = 1.72; 95% CI, 1.29-2.31), caregivers' concern about having had COVID-19 themselves at the time of survey completion in the ED (OR = 1.1; 95% CI, 1.05-1.16), and caregivers' intent to have their children vaccinated against COVID-19 if a vaccine were to become available (OR = 1.84; 95% CI, 1.54-2.21). Compared with fathers, mothers completing the survey were less likely to approve of changes in the vaccine-development process (OR = 0.641; 95% CI, 0.529-0.775). IMPLICATIONS: Less than half of caregivers in this worldwide sample were willing to accept abbreviated COVID-19 vaccine testing. As a part of an effort to increase acceptance and uptake of a new vaccine, especially in order to protect children, public health strategies and individual providers should understand caregivers' attitudes toward the approval of a vaccine and consult them appropriately.

RESUMO

BACKGROUND: More than 100 COVID-19 vaccine candidates are in development since the SARS-CoV-2 genetic sequence was published in January 2020. The uptake of a COVID-19 vaccine among children will be instrumental in limiting the spread of the disease as herd immunity may require vaccine coverage of up to 80% of the population. Prior history of pandemic vaccine coverage was as low as 40% among children in the United States during the 2009 H1N1 influenza pandemic. PURPOSE: To investigate predictors associated with global caregivers' intent to vaccinate their children against COVID-19, when the vaccine becomes available. METHOD: An international cross sectional survey of 1541 caregivers arriving with their children to 16 pediatric Emergency Departments (ED) across six countries from March 26 to May 31, 2020. RESULTS: 65% (n = 1005) of caregivers reported that they intend to vaccinate their child against COVID-19, once a vaccine is available. A univariate and subsequent multivariate analysis found that increased intended uptake was associated with children that were older, children with no chronic illness, when fathers completed the survey, children up-to-date on their vaccination schedule, recent history of vaccination against influenza, and caregivers concerned their child had COVID-19 at the time of survey completion in the ED. The most common reason reported by caregivers intending to vaccinate was to protect their child (62%), and the most common reason reported by caregivers refusing vaccination was the vaccine's novelty (52%). CONCLUSIONS: The majority of caregivers intend to vaccinate their children against COVID-19, though uptake will likely be associated with specific factors such as child and caregiver demographics and vaccination history. Public health strategies need to address barriers to uptake by providing evidence about an upcoming COVID-19 vaccine's safety and efficacy, highlighting the risks and consequences of infection in children, and educating caregivers on the role of vaccination.

RESUMO

BACKGROUND: Frontotemporal lobar degeneration (FTLD) is a devastating and progressive disorder, and a common cause of early onset dementia. Progranulin (PGRN) haploinsufficiency due to autosomal dominant mutations in the progranulin gene (GRN) is an important cause of FTLD (FTLD-GRN), and nearly a quarter of these genetic cases are due to a nonsense mutation. Premature termination codons (PTC) can be therapeutically targeted by compounds allowing readthrough, and aminoglycoside antibiotics are known to be potent PTC readthrough drugs. Restoring endogenous PGRN through PTC readthrough has not previously been explored as a therapeutic intervention in FTLD. METHODS: We studied whether the aminoglycoside G418 could increase PGRN expression in HEK293 and human induced pluripotent stem cell (hiPSC)-derived neurons bearing the heterozygous S116X, R418X, and R493X pathogenic GRN nonsense mutations. We further tested a novel substituted phthalimide PTC readthrough enhancer in combination with G418 in our cellular models. We next generated a homozygous R493X knock-in hiPSC isogenic line (R493X-/- KI), assessing whether combination treatment in hiPSC-derived neurons and astrocytes could increase PGRN and ameliorate lysosomal dysfunction relevant to FTLD-GRN. To provide in vivo proof-of-concept of our approach, we measured brain PGRN after intracerebroventricular administration of G418 in mice expressing the V5-tagged GRN nonsense mutation R493X. RESULTS: The R418X and R493X mutant GRN cell lines responded to PTC readthrough with G418, and treatments increased PGRN levels in R493X-/- KI hiPSC-derived neurons and astrocytes. Combining G418 with a PTC readthrough enhancer increased PGRN levels over G418 treatment alone in vitro. PGRN deficiency has been shown to impair lysosomal function, and the mature form of the lysosomal protease cathepsin D is overexpressed in R493X-/- KI neurons. Increasing PGRN through G418-mediated PTC readthrough normalized this abnormal lysosomal phenotype in R493X-/- KI neuronal cultures. A single intracerebroventricular injection of G418 induced GRN PTC readthrough in 6-week-old AAV-GRN-R493X-V5 mice. CONCLUSIONS: Taken together, our findings suggest that PTC readthrough may be a potential therapeutic strategy for FTLD caused by GRN nonsense mutations.

RESUMO

Goal: COSMIC Medical, a Vancouver-based open-source volunteer initiative, has designed an accessible, affordable, and aerosol-confining non-invasive positive-pressure ventilator (NIPPV) device, known as the COSMIC Bubble Helmet (CBH). This device is intended for COVID-19 patients with mild-to-moderate acute respiratory distress syndrome. System Design: CBH is composed of thermoplastic polyurethane, which creates a flexible neck seal and transparent hood. This device can be connected to wall oxygen, NIPPVs including Continuous Positive Airway Pressure and Bi-level Positive Airway Pressure, and mechanical ventilators. Discussion: Justification of CBH design components relied on several factors, predominantly the safety and comfort of patients and healthcare providers. Conclusion: CBH has implications within and outside of the pandemic, as an alternative to invasive mechanical ventilation methods. We have experimentally verified that CBH is effective in minimizing aerosolization risks and performs at specified clinical requirements.
