A Survey of Vascular Surgery Program Directors: Perspectives following USMLE Step 1 Conversion to Pass/Fail and Virtual Only Interviews.

BACKGROUND: Step 1 of the United States Medical Licensing Examination (USMLE), a historically important factor in the selection of vascular surgery residents and fellows, transitioned to completely pass/fail on January 26, 2022. Due to the COVID-19 pandemic, residency and fellowship interviews were conducted virtually during the 2020-21 and 2021-22 application cycles. Given these significant changes in the evaluation of candidates for residency training, we sought to understand vascular surgery program directors' (PDs) perspectives regarding the change in step 1 scoring and use of virtual interviews as well as determine which factors will assume importance when applying to vascular surgery training programs in the future. METHODS: A 26-item survey questionnaire was created using Qualtrics survey tools with questions regarding attitudes toward the change in step 1 scoring and virtual interviews, the importance of additional factors utilized by programs in selecting candidates for interviews and ranking applicants for residency/fellowship selection, and programmatic demographics. This was distributed anonymously to all vascular surgery training programs over a 2-week period using a comprehensive list of 249 unique email addresses created by cross-referencing the Accreditation Council for Graduate Medical Education list of certified vascular training programs with email addresses from individual program websites identifying current program leadership. Responses were analyzed with descriptive statistics with values listed as average Likert scale weight ± standard deviation (SD) or percentages. RESULTS: Sixty-eight of 249 (27.3%) program and associate PDs responded to the survey. Of which, 33.9% of respondents strongly disagreed with step 1 going completely pass/fail. In the absence of a scored USMLE step 1, letters of recommendation (average Likert scale weight ± SD, 4.43 ± 0.92), dedication to specialty (4.14 ± 1.03), and USMLE step 2 CK (4.06 ± 0.92) had the highest average scores for deciding which applicants to interview for integrated vascular surgery residency. For determining which candidates to interview for vascular surgery fellowship, letters of recommendation (4.51 ± 0.84), dedication to specialty (4.12 ± 0.90), and research (4.10 ± 0.80) had the highest average scores. For ranking residency candidates, the interviewee's perceived "fit" (4.61 ± 0.55), letters of recommendation (4.53 ± 0.76), and an overall interview experience (4.47 ± 0.62) had the highest average scores. Similarly, the factors with the highest average Likert scores for ranking fellowship candidates included the interviewee's perceived "fit" (4.69 ± 0.51), letters of recommendation (4.65 ± 0.52), and an overall interview experience (4.51 ± 0.59). The majority (72.2%) of PDs preferred in-person interviews; however, 50% of respondents were at least "somewhat satisfied" with virtual interviews during the 2021-22 application cycle as they could judge applicants' interview skills at least "moderately well." The minority (18.8%) who preferred virtual interviews most commonly noted a "reduction of the financial burden for applicants" as the reason for this preference. CONCLUSIONS: Most vascular surgery program and associate PDs were dissatisfied with USMLE step 1 going pass/fail with most indicating prescreening applicants using both step 1 and step 2 clinical knowledge (CK) during the residency and fellowship selection processes. In the absence of a scored step 1, the top factors for interviewing and ranking integrated vascular surgery residency and fellowship candidates included letters of recommendation, dedication to specialty, research, USMLE step 2 CK, the interviewee's perceived "fit," and overall interview experience. Though most PDs preferred face-to-face interviews, they were overall at least "somewhat satisfied" with the virtual format that took place during the 2021-22 cycle.

Immunogenicity of BNT162b2 COVID-19 vaccine in New Zealand adults.

BACKGROUND: There is very little known about SARS-CoV-2 vaccine immune responses in New Zealand populations at greatest risk for serious COVID-19 disease. METHODS: This prospective cohort study assessed immunogenicity in BNT162b2 mRNA vaccine recipients in New Zealand without previous COVID-19, with enrichment for Maori, Pacific peoples, older adults ≥ 65 years of age, and those with co-morbidities. Serum samples were analysed at baseline and 28 days after second dose for presence of quantitative anti-S IgG by chemiluminescent microparticle immunoassay and for neutralizing capacity against Wuhan, Beta, Delta, and Omicron BA.1 strains using a surrogate viral neutralisation assay. RESULTS: 285 adults with median age of 52 years were included. 55% were female, 30% were Maori, 28% were Pacific peoples, and 26% were ≥ 65 years of age. Obesity, cardiac and pulmonary disease and diabetes were more common than in the general population. All participants received 2 doses of BNT162b2 vaccine. At 28 days after second vaccination, 99.6% seroconverted to the vaccine, and anti-S IgG and neutralising antibody levels were high across gender and ethnic groups. IgG and neutralising responses declined with age. Lower responses were associated with age ≥ 75 and diabetes, but not BMI. The ability to neutralise the Omicron BA.1 variant in vitro was severely diminished but maintained against other variants of concern. CONCLUSIONS: Vaccine antibody responses to BNT162b2 were generally robust and consistent with international data in this COVID-19 naïve cohort with representation of key populations at risk for COVID-19 morbidity. Subsequent data on response to boosters, durability of responses and cellular immune responses should be assessed with attention to elderly adults and diabetics.

A Third Pandemic is on the Horizon

The emergence of the novel SARS-CoV-2 virus and the resultant COVID-19 pandemic has brought the world to a standstill. In the United States, the morbidity and mortality associated with COVID-19 infection has disproportionately impacted Black, Indigenous and People of Color (BIPOC) communities, highlighting an underlying "second pandemic" perpetuated by the deeply-rooted health care inequities and social determinants of health. In this manuscript, we warn about a "Third Pandemic" on the horizon which could be driven by federal policies that fail to ensure equitable access to COVID-specific therapeutics for BIPOC communities, and the potential inequitable implementation of such policies that could further perpetuate disparities in health outcomes.

The effect of a safety crisis on safety culture and safety climate: The resilience of a flight training organization during COVID-19.

Flight training programs incur great risks as they instruct aspiring pilots to complete flight training and licensing procedures. It is instrumental for these programs to create strong safety cultures and climates to promote the highest level of safety possible. The COVID-19 pandemic raised many safety concerns across a variety of industries, especially the aviation industry. This study investigates the impact that the COVID-19 pandemic had on the safety culture and safety climate of the flight training organization at Embry-Riddle Aeronautical University (ERAU). For this purpose, we collected longitudinal data for the years 2018 through 2021 including the variables of safety culture and safety climate. The results of this research suggest that various safety culture and safety climate variables were impacted during the COVID-19 pandemic. Based on these results, leadership of the flight training program was able to mitigate and adjust safety policies and procedures to improve the safety culture and climate and ensure continuous accident-free performance. Finally, the viability of these and other safety procedures for the safe management of future crises are discussed.

An Infant with COVID-19-Associated Intussusception.

Intussusception is the most common cause of bowel obstruction in infants four to ten months old and is commonly idiopathic or attributed to lymphoid hyperplasia. Our patient was a 7-month-old male who presented with two weeks of intermittent abdominal pain associated with crying, fist clenching and grimacing. Ultrasound demonstrated an ileocolic intussusception in the right abdomen. Symptoms resolved after contrast enemas, and he was discharged home. He re-presented similarly the next day and was found to be COVID-19 positive. Computed tomography scan demonstrated a left upper quadrant ileal-ileal intussusception. His symptoms spontaneously resolved, and he was discharged home. This suggests that COVID-19 may be a cause of intussusception in infants, and infants presenting with intussusception should be screened for this virus. Additionally, recurrence may happen days later at different intestinal locations. Caregiver education upon discharge is key to monitor for recurrence and need to return.

Ocular Injury Associated With Prone Positioning in Adult Critical Care: A Systematic Review and Meta-Analysis.

PURPOSE: Prone positioning during the COVID-19 pandemic has become increasingly used as an adjunct to increase oxygenation in critical care patients. It is associated with an adverse event profile. This study sought to investigate the occurrence of ocular injuries reported in prone versus supine groups in adult critical care. DESIGN: Systematic review and meta-analysis. METHODS: A systematic review and meta-analysis were carried out in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, SCOPUS, and the Cochrane Library were searched. The search period was January 1, 1990, to July 1, 2020. RESULTS: Eleven randomized controlled trials were included, with 2,247 patients. Twenty-eight events were recorded in 3 trials (174 patients) and no events in the other 8 trials (2,073 patients). The rates of eye injury were 5 events in 1,158 patients (1.30%) and 13 events in 1,089 patients (1.19%) in the prone and supine groups, respectively, which were reduced to 2 of 1,158 patients (0.17%) and 2 of 1,089 patients (0.18%), respectively, when reports of eye or eyelid edema were removed. Meta-analysis demonstrated no significant differences between groups with (an OR of 1.40 (95% CI: 0.37-5.27) and without (OR: 0.78; 95% CI: 0.11-5.73) reported edema. CONCLUSIONS: This meta-analysis showed no significant difference in the rate of reported ocular injury between prone and supine critical care groups. These rates remain higher than the incidence reported during general anesthesia. There is a need for studies in critical care settings in which ocular injury is an end-point and which include extended patient follow-up.

Differences in rapid increases in county-level COVID-19 incidence by implementation of statewide closures and mask mandates - United States, June 1-September 30, 2020.

BACKGROUND AND OBJECTIVE: Community mitigation strategies could help reduce COVID-19 incidence, but there are few studies that explore associations nationally and by urbanicity. In a national county-level analysis, we examined the probability of being identified as a county with rapidly increasing COVID-19 incidence (rapid riser identification) during the summer of 2020 by implementation of mitigation policies prior to the summer, overall and by urbanicity. METHODS: We analyzed county-level data on rapid riser identification during June 1-September 30, 2020 and statewide closures and statewide mask mandates starting March 19 (obtained from state government websites). Poisson regression models with robust standard error estimation were used to examine differences in the probability of rapid riser identification by implementation of mitigation policies (P-value< .05); associations were adjusted for county population size. RESULTS: Counties in states that closed for 0-59 days were more likely to become a rapid riser county than those that closed for >59 days, particularly in nonmetropolitan areas. The probability of becoming a rapid riser county was 43% lower among counties that had statewide mask mandates at reopening (adjusted prevalence ratio = 0.57; 95% confidence intervals = 0.51-0.63); when stratified by urbanicity, associations were more pronounced in nonmetropolitan areas. CONCLUSIONS: These results underscore the potential value of community mitigation strategies in limiting the COVID-19 spread, especially in nonmetropolitan areas.

The impact of a national COVID-19 lockdown on acute coronary syndrome hospitalisations in New Zealand (ANZACS-QI 55).

BACKGROUND: Countries with a high incidence of coronavirus 2019 (COVID-19) reported reduced hospitalisations for acute coronary syndromes (ACS) during the pandemic. This study describes the impact of a nationwide lockdown on ACS hospitalisations in New Zealand (NZ), a country with a low incidence of COVID-19. METHODS: All patients admitted to a NZ Hospital with ACS who underwent coronary angiography in the All NZ ACS Quality Improvement registry during the lockdown (23 March - 26 April 2020) were compared with equivalent weeks in 2015-2019. Ambulance attendances and regional community troponin-I testing were compared for lockdown and non-lockdown (1 July 2019 to 16 February 2020) periods. FINDINGS: Hospitalisation for ACS was lower during the 5-week lockdown (105 vs. 146 per-week, rate ratio 0•72 [95% CI 0•61-0•83], p = 0.003). This was explained by fewer admissions for non-ST-segment elevation ACS (NSTE-ACS; p = 0•002) but not ST-segment elevation myocardial infarction (STEMI; p = 0•31). Patient characteristics and in-hospital mortality were similar. For STEMI, door-to-balloon times were similar (70 vs. 72 min, p = 0•52). For NSTE-ACS, there was an increase in percutaneous revascularisation (59% vs. 49%, p<0•001) and reduction in surgical revascularisation (9% vs. 15%, p = 0•005). There were fewer ambulance attendances for cardiac arrests (98 vs. 110 per-week, p = 0•04) but no difference for suspected ACS (408 vs. 420 per-week, p = 0•44). Community troponin testing was lower throughout the lockdown (182 vs. 394 per-week, p<0•001). INTERPRETATION: Despite the low incidence of COVID-19, there was a nationwide decrease in ACS hospitalisations during the lockdown. These findings have important implications for future pandemic planning. FUNDING: The ANZACS-QI registry receives funding from the New Zealand Ministry of Health.
