RESUMO
OBJECTIVE: The goals of this study were (1) to assess if examiner ratings in the American Board of Surgery (ABS) General Surgery Cetifying Exam (CE) are biased based on the gender, race, and ethnicity of the candidate or the examiners, and (2) if the format of delivering of the exams, in-person or virtual, affects how examiners rate candidates. DESIGN: We included every candidate-examiner combination for first time takers of the general surgery oral exam. Total scores and pass/fail outcomes based on the 4 scores given by examiners to candidates were analyzed using multilevel models, with candidates as random effects. Explanatory variables included the gender, race, and ethnicity of candidates and examiners, and the format of the exam (in-person or virtual). Candidates' first attempt scores on the ABS General Surgery Qualifying Exam (QE) were also included in the models to control for the baseline knowledge of the candidate. Three sets of models were evaluated for each demographic variable (gender, race, ethnicity) due to missingness in data. p-values and coefficients of determination R2 were used to quantify the statistical and practical significance of the model coefficients (an existent relationship between the explored variables on CE scores was considered statistically and practically significant if the p-value was lower than 0.01 and R2 higher than 1%). PARTICIPANTS: All first-time takers of the American Board of Surgery General Surgery Certifying Exam from 2016 to 2022 that had demographic data, and the examiners that participated in those exams. RESULTS: The number of candidates/examiners for the 3 sets of models was 8665/514 (gender), 5906/465 (race), and 4678/295 (ethnicity). The demographic variables, format of the exam, or their interactions were not found to significantly relate to examiner-candidate ratings or pass/fail outcomes. The only variable that was significantly related to CE scores was candidates' QE scores, which was added to the models as a measure of candidates' initial knowledge; this held for all models for total scores (F[1,8659]â¯=â¯1069.89, p-value < 0.01, R2â¯=â¯5% [gender models], F(1,5696.3)â¯=â¯589.13, p-value < 0.01, R2â¯=â¯5% [race models], F(1,4459.5)â¯=â¯278.33, p-value < 0.01, R2â¯=â¯5% [ethnicity models]), and pass/fail outcomes (CIâ¯=â¯1.61-1.73, p-value < 0.01, R2â¯=â¯3% [gender models], CIâ¯=â¯1.67-1.85, p-value < 0.01, R2â¯=â¯3% [race models], CIâ¯=â¯2.17-2.90, p-value < 0.01, R2â¯=â¯3% [ethnicity models]). CONCLUSIONS: This study shows that there is not a relationship between candidate and examiner gender, race, or ethnicity, and exam outcomes based on statistical models looking at examiner-candidate ratings and pass/fail outcomes. In addition, the delivery of the certifying exam in a virtual format appears to have no statistical impact on outcomes compared to in-person delivery. This suggests that the ABS is performing well in both demographic bias and virtual space.

OBJECTIVE: Historically, the American Board of Surgery required surgeons to pass the qualifying examination (QE) before taking the certifying examination (CE). However, in the 2020-2021 academic year, with mitigating circumstances related to COVID-19, the ABS removed this sequencing requirement to facilitate the certification process for those candidates who were negatively impacted by a QE delivery failure. This decoupling of the traditional order of exam delivery has provided a natural comparator to the traditional route and an analysis of the impact of examination sequencing on candidate performance. METHODS: All candidates who applied for the canceled July 2020 QE were allowed to take the CE before passing the QE. The sample was then reduced to include only first-time candidates to ensure comparable groups for performance outcomes. Logistic regression was used to analyze the relationship between the order of taking the QE and the CE, controlling for other examination performance, international medical graduate status, and gender. RESULTS: Only first-time candidates who took both examinations were compared (n=947). Examination sequence was not a significant predictor of QE pass/fail outcomes, OR=0.54; 95% CI, 0.19-1.61, P =0.26. However, examination sequence was a significant predictor of CE pass/fail outcomes, OR=2.54; 95% CI, 1.46-4.68, P =0.002. CONCLUSIONS: This important study suggests that preparation for the QE increases the probability of passing the CE and provides evidence that knowledge may be foundational for clinical judgment. The ABS will consider these findings for examination sequencing moving forward.

Dual targeted therapy (DTT) has emerged as a promising approach in patients with refractory spondyloarthritis (SpA) or psoriatic arthritis (PsA) and extra-musculoskeletal manifestations of both diseases, but its effectiveness/safety ratio still remains unclear. This is a retrospective, real-world multicenter study in refractory SpA and PsA patients with simultaneous use of two biological or synthetic targeted agents. Effectiveness was assessed using Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS-CRP) and Disease Activity in Psoriatic Arthritis (DAPSA) Score. We identified 39 different DTT combinations in 36 patients (22 SpA; 14 PsA), 25 of them with concomitant inflammatory bowel disease. The most commonly used combinations were TNF inhibitor plus antagonist of the IL12/23 pathway, followed by TNF inhibitor plus IL-17 antagonist. During a median exposure of 14.86 months (IQR 8-20.2), DTT retention rate was 69.4% (n=25/36; 19 SpA, 6 PsA). Major clinical improvement (change in ASDAS-CRP > 2 or improvement > 85% in DAPSA) was achieved in 69.4% of patients (n=25/36 therapeutical combinations; 17/21 SpA, 8/15 PsA), with a 58.3% (n=21/36 combinations; 15/20 SpA, 6/13 PsA) low-activity/remission rate. Of the patients who were receiving glucocorticoids, 55% managed to withdraw them during follow-up. Interestingly, only four serious adverse events in three patients were observed, leading to DTT discontinuation.

BACKGROUND: To evaluate the real-world effect of the IL-12/23 inhibitor ustekinumab or of a tumour necrosis factor inhibitor (TNFi) on patient-reported outcomes (PRO) and their association with effectiveness endpoints in psoriatic arthritis (PsA) patients over 3 years. METHODS: In PsABio (NCT02627768), a prospective, observational study, patients with PsA that were prescribed first- to third-line ustekinumab or a TNFi, and remained on that drug for 3 years, were analysed for change in baseline in PROs (EuroQol-5 dimensions health state VAS [EQ-5D VAS], 12-item Psoriatic Arthritis Impact of Disease questionnaire [PsAID-12; range 0-10], Work Productivity and Activity Impairment for Psoriatic Arthritis questionnaire [WPAI; results expressed as a percentage for each domain]), and the association between PROs and WPAI with effectiveness endpoints, clinical disease activity index for psoriatic arthritis (cDAPSA), low disease activity (LDA)/remission, minimal disease activity (MDA) and very low disease activity (VLDA). RESULTS: In 437 patients (mean age 49.1 years, 47.8% female), at 3 years, ustekinumab and TNFi treatment led to comparable improvements in EQ-5D VAS; mean change from baseline (95% confidence intervals [CI]) was 11.0 (6.5; 15.4) and 18.9 (14.0; 23.9), respectively. Both groups improved PsAID-12 after 3 years; mean change from baseline (95% CI) was -2.9 (-3.2; -2.5) and -3.5 (-3.9; -3.2), respectively. At baseline, due to their PsA, TNFi-treated patients had lower work productivity compared to ustekinumab-treated patients; mean productivity reduction (95% CI) was 58.8 [52.4; 65.2] and 43.3 [35.6; 51.1]. Over 3 years, TNFi-treated patients had a greater improvement in work productivity compared to ustekinumab-treated patients, ultimately leaving work productivity to be comparable between groups; mean improvement (95% CI) was 44.5% (38.4; 50.6) and 24.9% (15.8; 34.0), respectively. A similar trend was observed in activity impairment. Patients in both treatment groups who achieved effectiveness endpoints, cDAPSA LDA/remission, MDA, and VLDA had greater improvement in PROs and WPAI than patients who did not achieve these endpoints. CONCLUSIONS: At 3 years, improvements in PROs following ustekinumab or TNFi treatment were generally comparable; however, TNFi-treated patients achieved a greater improvement in work productivity, although this group started from a lower baseline. Achievement of effectiveness endpoints, independent of treatment group, also improved PROs. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02627768. Registered on 11 December 2015.

OBJECTIVE: Investigate effects of gender on disease characteristics and treatment impact in patients with PsA. METHODS: PsABio is a non-interventional European study in patients with PsA starting a biological DMARD [bDMARD; ustekinumab or TNF inhibitor (TNFi)]. This post-hoc analysis compared persistence, disease activity, patient-reported outcomes and safety between male and female patients at baseline and 6 and 12 months of treatment. RESULTS: At baseline, disease duration was 6.7 and 6.9 years for 512 females and 417 males respectively. Mean (95% CI) scores for females vs males were: clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA), 32.3 (30.3, 34.2) vs 26.8 (24.8, 28.9); HAQ-Disability Index (HAQ-DI), 1.3 (1.2, 1.4) vs 0.93 (0.86, 0.99); total PsA Impact of Disease-12 (PsAID-12) score, 6.0 (5.8, 6.2) vs 5.1 (4.9, 5.3), respectively. Improvements in scores were smaller in female than male patients. At 12 months, 175/303 (57.8%) female and 212/264 (80.3%) male patients achieved cDAPSA low disease activity, 96/285 (33.7%) and 137/247 (55.5%), achieved minimal disease activity (MDA), respectively. HAQ-DI scores were 0.85 (0.77, 0.92) vs 0.50 (0.43, 0.56), PsAID-12 scores 3.5 (3.3, 3.8) vs 2.4 (2.2, 2.6), respectively. Treatment persistence was lower in females than males (P ≤ 0.001). Lack of effectiveness was the predominant reason to stop, irrespective of gender and bDMARD. CONCLUSIONS: Before starting bDMARDs, females had more severe disease than males and a lower percentage reached favourable disease states, with lower persistence of treatment after 12 months. A better understanding of the mechanisms underlying these differences may improve therapeutic management in females with PsA.

The aim was to identify patient- and disease-related characteristics predicting moderate-to-high disease activity in recent-onset psoriatic arthritis (PsA). We performed a multicenter observational prospective study (2-year follow-up, regular annual visits) in patients aged ≥18 years who fulfilled the CASPAR criteria and had less than 2 years since the onset of symptoms. The moderate-to-high activity of PsA was defined as DAPSA > 14. We trained a logistic regression model and random forest-type and XGBoost machine learning algorithms to analyze the association between the outcome measure and the variables selected in the bivariate analysis. The sample comprised 158 patients. At the first follow-up visit, 20.8% of the patients who attended the clinic had a moderate-to-severe disease. This percentage rose to 21.2% on the second visit. The variables predicting moderate-high activity were the PsAID score, tender joint count, level of physical activity, and sex. The mean values of the measures of validity of the machine learning algorithms were all high, especially sensitivity (98%; 95% CI: 86.89-100.00). PsAID was the most important variable in the prediction algorithms, reinforcing the convenience of its inclusion in daily clinical practice. Strategies that focus on the needs of women with PsA should be considered.
RESUMO
OBJECTIVES: To evaluate real-world persistence and effectiveness of the IL-12/23 inhibitor, ustekinumab or a tumour necrosis factor inhibitor (TNFi) for psoriatic arthritis over 3 years. METHODS: PsABio (NCT02627768), a prospective, observational study, followed patients with PsA prescribed first-line to third-line ustekinumab or a TNFi. Persistence and effectiveness (achievement of clinical Disease Activity for PSA (cDAPSA) low disease activity (LDA)/remission and minimal disease activity/very LDA (MDA/VLDA)) were assessed every 6 months. Safety data were collected over 3 years. Analyses to compare the modes of action were adjusted on baseline differences by propensity scores (PS). RESULTS: In 895 patients (mean age 49.8 years, 44.7% males), at 3 years, the proportion of patients still on their initial treatments was similar with ustekinumab (49.9%) and TNFi (47.8%). No difference was seen in the risk of stopping/switching; PS-adjusted hazard ratio (95% CI) for stopping/switching ustekinumab versus TNFi was 0.87 (0.68 to 1.11). In the overall population, cDAPSA LDA/remission was achieved in 58.6%/31.4% ustekinumab-treated and 69.8%/45.0% TNFi-treated patients; PS-adjusted ORs (95% CI) were 0.89 (0.63 to 1.26) for cDAPSA LDA; 0.72 (0.50 to 1.05) for remission. MDA/VLDA was achieved in 41.4%/19.2% of ustekinumab-treated and 54.2%/26.9% of TNFi-treated patients with overlapping PS-adjusted ORs. A greater percentage of TNFi-treated patients achieved effectiveness outcomes. Both treatments exhibited good long-term safety profiles, although ustekinumab-treated patients had a lower rate of adverse events (AEs) versus TNFi. CONCLUSION: At 3 years, there was generally comparable persistence after ustekinumab or TNFi treatment, but AE rates were lower with ustekinumab.

OBJECTIVE: The American Board of Surgery (ABS) sought to investigate the suitability of video-based assessment (VBA) as an adjunct to certification for assessing technical skills. BACKGROUND: Board certification is based on the successful completion of a residency program coupled with knowledge and reasoning assessments. VBA is a new modality for evaluating operative skills that have been shown to correlate with patient outcomes after surgery. METHODS: Diplomates of the ABS were initially assessed for background knowledge and interest in VBA. Surgeons were then solicited to participate in the pilot. Three commercially available VBA platforms were identified and used for the pilot assessment. All participants served as reviewers and reviewees for videos. After the interaction, participants were surveyed regarding their experiences and recommendations to the ABS. RESULTS: To the initial survey, 4853/25,715 diplomates responded. The majority were neither familiar with VBA, nor the tools used for operative assessments. Two hundred seventy-four surgeons actively engaged in the subsequent pilot. One hundred sixty-nine surgeons completed the postpilot survey. Most participants found the process straightforward. Of the participants, 74% felt that the feedback would help their surgical practice. The majority (81%) remain interested in VBA for continuing medical education credits. Using VBA in continuous certification could improve surgeon skills felt by 70%. Two-thirds of participants felt VBA could help identify and remediate underperforming surgeons. Identified barriers to VBA included limitations for open surgery, privacy issues, and technical concerns. CONCLUSIONS: VBA is promising as an adjunct to the current board certification process and should be further considered by the ABS.

OBJECTIVES: To evaluate the effect of potential confounders on the association between sex and disease impact in recent-onset psoriatic arthritis. METHODS: We performed a multicentre observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. The dataset was generated using data for each patient at the 3 visits (baseline, first year, and second year of follow-up) matched with the PsAID values at each of the 3 visits. Once variables associated with both PsAID ≥4 and sex were selected, those that led to a difference of >10% between the adjusted and crude estimations were identified as potential confounders in the association between sex and PsAID. Lastly, the final multivariate logistic regression model estimating the association between sex and PsAID was defined. RESULTS: The dataset contained 418 observations (158 at baseline, 135 at the first follow-up visit, and 125 at the second visit). The confounders identified in the multivariate model were HAQ, global pain, level of physical activity, and joint pattern at diagnosis. After adjustment for these variables, no statistically significant association was observed between female sex and PsAID ≥4. CONCLUSIONS: The association between female sex and greater disease impact could be explained by the influence of other variables, specifically higher HAQ score, greater intensity of pain, differences in the level of physical activity and in the joint pattern at diagnosis (lower frequency of the spondylitis pattern in women).

OBJECTIVE: To compare the operative experience of general surgery residents and practicing general surgeons. SUMMARY OF BACKGROUND DATA: The scope of general surgery has evolved, yet it remains unknown whether residents are being exposed to the right mix of operations during residency. METHODS: A retrospective review of operative case logs submitted to the American Board of Surgery by US general surgery graduates and practicing general surgeons from 2013 to 2017 was performed. The operative experience of both cohorts was calculated as a proportion of total experience and ranked by frequency. The proportional experience between cohorts was analyzed using factorial analysis of variance. RESULTS: During the 5-year period, 5482 graduates applied for initial American Board of Surgery certification, and 4152 diplomates applied for recertification. Among all operative domains, the graduate experience was similar to that of diplomates in 6 of 12 areas (abdomen, alimentary tract, endoscopy, endocrine, other, skin/soft tissue; all P > 0.05). Residents have a greater experience in subspecialty areas (pediatric, thoracic, trauma, vascular, and plastic) at the expense of fewer breast procedures (all P < 0.05). The 30 operations most commonly performed by graduates comprised 67% of their total operative experience. Among these, residents performed 25 cases ≥10 times, 14 cases ≥20 times, and 7 cases ≥40 times. CONCLUSIONS: The operative experience of graduating US general surgery residents is largely similar to that of practicing general surgeons, particularly for core general surgery domains. These data offer reassurance that surgical training in the modern era appropriately exposes residents to the operations they may perform in practice.

The slope of a supracellular molecular gradient has long been thought to orient and coordinate planar cell polarity (PCP). Here we demonstrate and measure that gradient. Dachsous (Ds) is a conserved and elemental molecule of PCP; Ds forms intercellular bridges with another cadherin molecule, Fat (Ft), an interaction modulated by the Golgi protein Four-jointed (Fj). Using genetic mosaics and tagged Ds, we measure Ds in vivo in membranes of individual cells over a whole metamere of the Drosophila abdomen. We find as follows. (i) A supracellular gradient rises from head to tail in the anterior compartment (A) and then falls in the posterior compartment (P). (ii) There is more Ds in the front than the rear membranes of all cells in the A compartment, except that compartment's most anterior and most posterior cells. There is more Ds in the rear than in the front membranes of all cells of the P compartment. (iii) The loss of Fj removes intracellular asymmetry anteriorly in the segment and reduces it elsewhere. Additional experiments show that Fj makes PCP more robust. Using Dachs (D) as a molecular indicator of polarity, we confirm that opposing gradients of PCP meet slightly out of register with compartment boundaries.

OBJECTIVES: To evaluate which patient and disease characteristics are associated with the perception of high-impact disease (PsAID ≥4) in recent-onset psoriatic arthritis. METHODS: We performed a multicenter observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. The dataset was generated using data for each patient at the 3 visits (baseline, first year, and second year of follow-up) matched with the PsAID values at each of the 3 visits. PsAID was categorized into two groups (<4 and ≥4). We trained a logistic regression model and random forest-type and XGBoost machine learning algorithms to analyze the association between the outcome measure and the variables selected in the bivariate analysis. A k-fold cross-validation with k = 5 was performed. RESULTS: The sample comprised 158 patients. Of the patients who attended the clinic, 45.8% scored PsAID ≥4 at baseline; 27.1%, at the first follow-up visit, and in 23.0%, at the second follow-up visit. The variables associated with PsAID ≥4 were, in decreasing order of importance: HAQ, pain, educational level, and physical activity. Higher HAQ (logistic regression coefficient 10.394; IC95% 7.777,13.011), higher pain (5.668; 4.016, 7.320), lower educational level (-2.064; -3.515, -0.613) and high level of physical activity (1.221; 0.158, 2.283) were associated with a higher frequency of PsAID ≥4. The mean values of the measures of validity of the algorithms were all ≥85%. CONCLUSIONS: Despite the higher weight given to pain when scoring PsAID, we observed a greater influence of physical function on disease impact.

OBJECTIVE: To measure associations between surgeons' examination performance and obtaining American Board of Surgery certification with the likelihood of having medical malpractice payments. BACKGROUND: Further research is needed to establish a broader understanding of the association of board certification and patient and practice outcomes. METHODS: Retrospective analysis using propensity score-matched surgeons who attempted to obtain American Board of Surgery certification. Surgeons who completed residency between 2000 and 2019 (n=910) and attempted to become certified were categorized as certified or failing to obtain certification. In addition, groups were categorized as either passing or failing their first attempt on the qualifying and certifying examinations. Malpractice payment reports were dichotomized for surgeons who either had a payment report or not. RESULTS: The hazard rate (HR) of malpractice payment reports was significantly greater for surgeons who attempted and failed to obtain certification [HR=1.87; 95% confidence interval (CI), 1.28-2.74] than for surgeons who were certified. Moreover, surgeons who failed either the qualifying (HR=1.64; 95% CI, 1.14-2.37) or certifying examination (HR=1.72; 95% CI, 1.14-2.60) had significantly higher malpractice payment HRs than those who passed the examinations on their first attempt. CONCLUSIONS: Failing to obtain board certification was associated with a higher rate of medical malpractice payments. In addition, failing examinations in the certification examination process on the first attempt was also associated with higher rates of medical malpractice payments. This study provides further evidence that board certification is linked to potential indicators for patient outcomes and practice quality.

OBJECTIVE: The onset of the COVID-19 (coronavirus disease 2019) pandemic mandated postponement of the in-person Vascular Surgery Board 2020 certifying examination (CE). Vascular surgery virtual CEs (VVCEs) were developed for the scheduled 2020 CEs (rescheduled to January 2021) and 2021 CEs (rescheduled to July 2021) to avoid postponing the certification testing. In the present study, we have reported the development, implementation, and outcomes of the first two VVCEs. METHODS: The VVCE was similar to the in-person format (three 30-minutes sessions, two examiners, four questions) but required a proctor and a host. In contrast to the general surgery VCEs, the VVCE also incorporated images. The candidates and examiners were instructed on the format, and technology checks were performed before the VVCE. The candidates were given the opportunity to invalidate their examination for technology-related reasons immediately after the examination. Postexamination surveys were administered to all the participants. RESULTS: The VVCEs were completed by 356 of 357 candidates (99.7%). The pass rates for the January 2021 and July 2021 examinations were 97.6% (first time, 99.4%; retake, 70%) and 94.7% (first time, 94.6%; retake, 100%), respectively. The pass rates were not significantly different from the 2019 in-person CE (χ2 = 2.30; P = .13; and χ2 = 0.01; P = .91, for the January 2021 and July 2021 examinations, respectively). None of the candidates had invalidated their examination. The candidates (162 of 356; 46%), examiners (64 of 118; 54%), proctors (25 of 27; 93%), and hosts (8 of 9; 89%) completing the survey were very satisfied with the examination (Likert score 4 or 5: candidates, 92.6%; noncandidates, 96.9%) and found the technology domains (Zoom, audio, video, viewing images) to be very good (Likert score 4 or 5), with candidate and other responder scores of 73% to 84% and >94%, respectively. Significantly more of the candidates had favored a future VVCE compared with the examiners (87% vs 32%; χ2 = 67.1; P < .001). The free text responses from all responders had commented favorably on the organization and implementation of the examination. However, some candidates had expressed concerns about image sizes, and some examiners had expressed concern about the time constraints for the question format. The candidates appreciated the convenience of an at-home examination, especially the avoidance of travel costs. CONCLUSIONS: The two Vascular Surgery Board VCEs were shown to be psychometrically sound and were overwhelmingly successful, demonstrating that image-based virtual examinations are feasible and could become the standard for the future.

BACKGROUND: Very few data are available on predictors of minimal disease activity (MDA) in patients with recent-onset psoriatic arthritis (PsA). Such data are crucial, since the therapeutic measures used to change the adverse course of PsA are more likely to succeed if we intervene early. In the present study, we used predictive models based on machine learning to detect variables associated with achieving MDA in patients with recent-onset PsA. METHODS: We performed a multicenter observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. The dataset contained data for the independent variables from the baseline visit and from follow-up visit number 1. These were matched with the outcome measures from follow-up visits 1 and 2, respectively. We trained a random forest-type machine learning algorithm to analyze the association between the outcome measure and the variables selected in the bivariate analysis. In order to understand how the model uses the variables to make its predictions, we applied the SHAP technique. We used a confusion matrix to visualize the performance of the model. RESULTS: The sample comprised 158 patients. 55.5% and 58.3% of the patients had MDA at the first and second follow-up visit, respectively. In our model, the variables with the greatest predictive ability were global pain, impact of the disease (PsAID), patient global assessment of disease, and physical function (HAQ-Disability Index). The percentage of hits in the confusion matrix was 85.94%. CONCLUSIONS: A key objective in the management of PsA should be control of pain, which is not always associated with inflammatory burden, and the establishment of measures to better control the various domains of PsA.

BACKGROUND: The demographics and operative experience of general surgeons certified by the American Board of Surgery were last examined a decade ago. This study examines the contemporary workforce and scope of practice of general surgeons. STUDY DESIGN: Applications of diplomates seeking American Board of Surgery recertification from 2013 to 2017 were reviewed. Demographic data and case logs from the year before submission were analyzed. Total operative volume was examined, as were total volumes for 13 operative domains and 11 abdominal and alimentary tract subdomains. RESULTS: There were 4,735 general surgeons certified by the American Board of Surgery with a mean ± SD age of 53 ± 8 years and included 19% women and 14% international graduates. Regions of practice were 22% Northeast, 31% Southeast, 20% Midwest, 20% West, and 7% Southwest. Practice settings were 86% urban, 9% large rural, 4% small rural, and 1% isolated. Forty-one percent were 10 years, 35% were 20 years, and 24% were 30 years since initial certification. On average, general surgeons performed 417 ± 338 procedures per year, with abdominal, alimentary tract, and endoscopy being the most common. On multivariable analysis, male sex and being midcareer or late career were positively associated with being a high-volume (top quartile) surgeon, whereas age and practicing in either the Northeast or West demonstrated a negative association. CONCLUSIONS: The demographics of general surgeons have remained stable over time, except for an increased proportion of female surgeons. The overall operative experience is similar to years past but is widely variable between surgeons. Periodic analysis of these data is important for education and certification purposes.

Objectives: To identify patient- and disease-related characteristics that make it possible to predict higher disease severity in recent-onset PsA. Methods: We performed a multicenter observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥ 18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. Severe disease was defined at each visit as fulfillment of at least 1 of the following criteria: need for systemic treatment, Health Assessment Questionnaire (HAQ) > 0.5, polyarthritis. The dataset contained data for the independent variables from the baseline visit and follow-up visit number 1. These were matched with the outcome measures from follow-up visits 1 and 2, respectively. We trained a logistic regression model and random forest-type and XGBoost machine learning algorithms to analyze the association between the outcome measure and the variables selected in the bivariate analysis. Results: The sample comprised 158 patients. At the first follow-up visit, 78.2% of the patients who attended the clinic had severe disease. This percentage decreased to 76.4% at the second visit. The variables predicting severe disease were patient global pain, treatment with synthetic DMARDs, clinical form at diagnosis, high CRP, arterial hypertension, and psoriasis affecting the gluteal cleft and/or perianal area. The mean values of the measures of validity of the machine learning algorithms were all ≥ 80%. Conclusion: Our prediction model of severe disease advocates rigorous control of pain and inflammation, also addressing cardiometabolic comorbidities, in addition to actively searching for hidden psoriasis.
RESUMO
OBJECTIVE: We evaluated real-world treatment persistence and effectiveness at 1 year following initiation of IL-12/23 inhibitor ustekinumab or a tumour necrosis factor inhibitor (TNFi) for psoriatic arthritis (PsA). METHODS: PsABio (NCT02627768), a prospective, observational study, followed patients with PsA prescribed first-line to third-line ustekinumab or TNFi. Drug persistence, effectiveness (achievement of clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) low disease activity (LDA)/remission and minimal disease activity/very low disease activity (MDA/VLDA)), and safety were assessed every 6 months. In addition to descriptive statistics, propensity score (PS)-adjusted comparisons across cohorts were performed. RESULTS: At 1 year, overall persistence was similar in the ustekinumab (n=317/438, 72.4%) and TNFi (n=321/455, 70.5%) groups. PS-adjusted HR (95% CI) for stopping/switching ustekinumab versus TNFi was 0.82 (0.60; 1.13). cDAPSA LDA (including remission)/remission was achieved in 55.9%/22.1% of ustekinumab-treated and 67.1%/31.7% of TNFi-treated patients; PS-adjusted ORs (95% CI) were 0.80 (0.57; 1.10) for cDAPSA LDA and 0.73 (0.49; 1.07) for remission. MDA/VLDA was achieved in 34.2%/11.9% of ustekinumab-treated and 43.1%/12.6% of TNFi-treated patients; PS-adjusted ORs (95% CI) were 0.89 (0.63; 1.26) for MDA and 0.90 (0.54; 1.49) for VLDA. The safety profiles were similar in both groups. CONCLUSION: In the real-world PsABio Study, after 1 year of treatment, although unadjusted persistence was numerically slightly higher for ustekinumab versus TNFi and unadjusted effectiveness was numerically slightly higher for TNFi versus ustekinumab, the PS-adjusted comparisons demonstrated comparable overall persistence, effectiveness and safety for both modes of action in PsA.

OBJECTIVE: To Study the Outcomes of the First Virtual General Surgery Certifying Exam of the American Board of Surgery. SUMMARY OF BACKGROUND DATA: The ABS General Surgery CE is normally an in-person oral examination. Due to the COVID-19 outbreak, the ABS was required to reschedule these. After 2 small pilots, the CE's October administration represented the first large-scale remote virtual exam. The purpose of this report is to compare the outcomes of this virtual and the previous in-person CEs. METHODS: CE candidates were asked to provide feedback on their experience via a survey. The passing rate was compared to the 1025 candidates who took the 2019-2020 in-person CEs. RESULTS: Of the 308 candidates who registered for the virtual CE, 306 completed the exam (99.4%) and 188 completed the survey (61.4%). The majority had a very positive experience. They rated the virtual CE as very good/excellent in security (90%), ease of exam platform (77%), audio quality (71%), video quality (69%), and overall satisfaction (86%). Notably, when asked their preference, 78% preferred the virtual exam. There were no differences in the passing rates between the virtual or in-person exams. CONCLUSIONS: The first virtual CE by the ABS was completed using available internet technology. There was high satisfaction, with the majority preferring the virtual platform. Compared to past in-person CEs, there was no difference in outcomes as measured by passing rates. These data suggest that expansion of the virtual CE may be desirable.

OBJECTIVES: To evaluate 6-month effectiveness of ustekinumab versus tumour necrosis factor inhibitor (TNFi), analysing predictors of low disease activity (LDA)/remission. METHODS: PsABio is a prospective, observational cohort study of patients with psoriatic arthritis (PsA) at 92 sites in eight European countries, who received first-line to third-line ustekinumab or a TNFi. Comparative achievement at 6 months of clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) LDA/remission, and minimal disease activity (MDA)/very LDA using propensity score (PS)-adjusted multivariate logistic regression was assessed. RESULTS: In the final analysis set of 868 participants with 6-month follow-up data (ustekinumab, n=426; TNFi, n=442), with long-standing disease and a high mean cDAPSA score (31.0 vs 29.8, respectively), proportions of patients in ustekinumab/TNFi treatment groups achieving cDAPSA LDA at 6 months were 45.7%/50.7%. cDAPSA remission was achieved in 14.9%/19.2%, and MDA in 26.4%/30.8% of patients. PS-adjusted odds ratios (OR; 95% confidence interval (CI)) of reaching cDAPSA LDA and MDA were 0.73 (0.46 to 1.15) and 0.87 (0.61 to 1.25) with ustekinumab versus TNFi, indicating no significant difference. High baseline body mass index or high cDAPSA were associated with a lower chance (OR (95% CI)) of reaching cDAPSA LDA with TNFi (0.94 (0.89 to 0.99) and 0.64 (0.52 to 0.79), respectively). Predictive factors were similar to previously published evidence, with cDAPSA and 12-item Psoriatic Arthritis Impact of Disease scores and chronic widespread pain at baseline appearing as new risk factors for unfavourable outcome. Safety data were similar between groups. CONCLUSION: Treatment targets were reached similarly after 6 months of treatment with ustekinumab and TNFi.
