RESUMO
BACKGROUND: Venous thromboembolism occurs in approximately 2% of patients undergoing abdominal and pelvic surgery for cancers of the colon, rectum, and anus and is considered preventable. The American Society of Colon and Rectal Surgeons recommends extended prophylaxis in high-risk patients, but there is low adherence to the guidelines. OBJECTIVE: This study aims to analyze the impact of venous thromboembolism risk-guided prophylaxis in patients undergoing elective abdominal and pelvic surgeries for colorectal and anal cancers from 2016 to 2021. DESIGN: This was a retrospective analysis. SETTING: The study was conducted at a multisite tertiary referral academic health care system. PATIENTS: Patients who underwent elective abdominal or pelvic surgery for colon, rectal, or anal cancer. MAIN OUTCOME MEASURES: Receipt of Caprini-guided venous thromboembolism prophylaxis, 90-day postoperative rate of deep vein thrombosis, pulmonary embolism, venous thromboembolism, and bleeding events. RESULTS: A total of 3504 patients underwent elective operations, of whom 2224 (63%) received appropriate thromboprophylaxis in the inpatient setting. In the postdischarged cohort of 2769 patients, only 2% received appropriate thromboprophylaxis and no thromboembolic events were observed. In the group receiving inappropriate thromboprophylaxis, at 90 days postdischarge, the deep vein thrombosis, pulmonary embolism, and venous thromboembolism rates were 0.60%, 0.40%, and 0.88%, respectively. Postoperative bleeding was not different between the 2 groups. LIMITATIONS: Limitations to our study include its retrospective nature, use of aggregated electronic medical records, and single health care system experience. CONCLUSION: Most patients in our health care system undergoing abdominal or pelvic surgery for cancers of the colon, rectum, and anus were discharged without appropriate Caprini-guided venous thromboembolism prophylaxis. Risk-guided prophylaxis was associated with decreased rates of inhospital and postdischarge venous thromboembolism without increased bleeding complications. See Video Abstract . MARGEN DE MEJORA EL IMPACTO DE LA TROMBOPROFILAXIS RECOMENDADA POR LAS DIRECTRICES EN PACIENTES SOMETIDOS A CIRUGA ABDOMINAL POR CNCER COLORRECTAL Y ANAL EN UN CENTRO DE REFERENCIA TERCIARIO: ANTECEDENTES:El tromboembolismo venoso ocurre en aproximadamente el 2% de los pacientes sometidos a cirugía abdominal y pélvica por cánceres de colon, recto y ano, y se considera prevenible. La Sociedad Estadounidense de Cirujanos de Colon y Recto recomienda una profilaxis prolongada en pacientes de alto riesgo, pero el cumplimiento de las directrices es bajo.OBJETIVO:Este estudio tiene como objetivo analizar el impacto de la profilaxis guiada por el riesgo de tromboembolismo venoso (TEV) en pacientes sometidos a cirugías abdominales y pélvicas electivas por cáncer colorrectal y anal entre 2016 y 2021.DISEÑO:Este fue un análisis retrospectivo.AJUSTE:El estudio se llevó a cabo en un sistema de salud académico de referencia terciaria de múltiples sitios.PACIENTES:Pacientes sometidos a cirugía abdominal o pélvica electiva por cáncer de colon, recto o ano.PRINCIPALES MEDIDAS DE RESULTADO:Recepción de profilaxis de tromboembolismo venoso guiada por Caprini, tasa postoperatoria de 90 días de trombosis venosa profunda, embolia pulmonar, tromboembolismo venoso y eventos de sangrado.RESULTADOS:Un total de 3.504 pacientes se sometieron a operaciones electivas, de los cuales 2.224 (63%) recibieron tromboprofilaxis adecuada en el ámbito hospitalario. En el cohorte de 2.769 pacientes después del alta, solo el 2% recibió tromboprofilaxis adecuada en la que no se observaron eventos tromboembólicos. En el grupo que recibió tromboprofilaxis inadecuada, a los 90 días después del alta, las tasas de trombosis venosa profunda, embolia pulmonar y tromboembolia venosa fueron del 0,60%, 0,40% y 0,88%, respectivamente. El sangrado posoperatorio no fue diferente entre los dos grupos.LIMITACIONES:Las limitaciones de nuestro estudio incluyen su naturaleza retrospectiva, el uso de registros médicos electrónicos agregados y la experiencia de un solo sistema de atención médica.CONCLUSIÓN:La mayoría de los pacientes en nuestro sistema de salud sometidos a cirugía abdominal o pélvica por cánceres de colon, recto y ano fueron dados de alta sin una profilaxis adecuada de TEV guiada por Caprini. La profilaxis guiada por el riesgo se asoció con menores tasas de tromboembolismo venoso hospitalario y dado de alta sin un aumento de las complicaciones de sangrado.

INTRODUCTION: This study examined simultaneous pancreas-kidney transplant (SPKt) in Black and White patients to identify disparities in transplantation, days on the waitlist, and reasons for SPKt waitlist removal. METHODS: Using the United Network for Organ Sharing Standard Transplant Analysis and Research file, patients between January 1, 2009, and May 31, 2021, were included. Three cohorts (overall, SPKt recipients only, and those not transplanted) were selected using propensity score matching. Conditional logistic regression was used for categorical outcomes. Days on the waitlist were compared using negative binomial regression. RESULTS: Black patients had increased odds of receiving a SPKt (OR, 1.25 [95% CI, 1.11-1.40], p < 0.001). White patients had increased odds of receiving a kidney-only transplant (OR 0.48 [95% CI, 0.38-0.61], p < 0.001), and specifically increased odds of receiving a living donor kidney (OR 0.34 [0.25-0.45], p < 0.001). CONCLUSION: This study found that Black patients are more likely to receive a SPKt. Results suggest that there are opportunities for additional inquiry related to patient removal from the waitlist, particularly considering White patients received or accepted more kidney-only transplants and were more likely to receive a living donor kidney-only transplant.

INTRODUCTION: The scarcity of available organs for kidney transplantation has resulted in a substantial waiting time for patients with end-stage kidney disease. This prolonged wait contributes to an increased risk of cardiovascular mortality. Calcification of large arteries is a high-risk factor in the development of cardiovascular diseases, and it is common among candidates for kidney transplant. The aim of this study was to correlate abdominal arterial calcification (AAC) score value with mortality on the waitlist. METHODS: We modified the coronary calcium score and used it to quantitate the AAC. We conducted a retrospective clinical study of all adult patients who were listed for kidney transplant, between 2005 and 2015, and had abdominal computed tomography scan. Patients were divided into two groups: those who died on the waiting list group and those who survived on the waiting list group. RESULTS: Each 1,000 increase in the AAC score value of the sum score of the abdominal aorta, bilateral common iliac, bilateral external iliac, and bilateral internal iliac was associated with increased risk of death (HR 1.034, 95% CI: 1.013, 1.055) (p = 0.001). This association remained significant even after adjusting for various patient characteristics, including age, tobacco use, diabetes, coronary artery disease, and dialysis status. CONCLUSION: The study highlights the potential value of the AAC score as a noninvasive imaging biomarker for kidney transplant waitlist patients. Incorporating the AAC scoring system into routine imaging reports could facilitate improved risk assessment and personalized care for kidney transplant candidates.

BACKGROUND: While racial disparity in surgical mortality due to venous thromboembolism (VTE) has improved, a gap persists. Our study aim was to determine differences in VTE prevention practices and their impact on outcomes among racial surgical cohorts. METHODS: Elective surgeries performed between 1.1.2016 and 5.31.2021 were included. Racial/ethnic cohorts were propensity-matched 1:1 to non-Hispanic White (NHW) patients, and outcomes were compared using unadjusted logistic regression. Match cohort balance was assessed using absolute standardized mean differences and linear model analysis of variance (ANOVA). Pearson's Chi-square tests evaluated bi-variate associations. Conditional logistic regression to compare outcomes between matched groups. Odds ratios, 95 â% confidence intervals, and p-values are reported. Analyses were performed using R version 4.1.2 and the R package Matchit. RESULTS: Non-Hispanic other race (NHOR) (vs. NHW) patients were less likely to receive inpatient prophylaxis (OR 0.86, CI:0.76-0.98). Appropriate prophylaxis resulted in similar VTE for NHB (p â= â0.71) and Hispanic (p â= â0.06), compared to NHW patients. Inpatient bleeding was higher in Hispanic patients with a higher likelihood of receiving appropriate prophylaxis (OR 1.94, CI:1.16-3.32) and NHOR patients with a lower likelihood (OR 1.90, CI:1.10-3.36) CONCLUSION: Postoperative VTE was similar for minority patients receiving appropriate prophylaxis, compared to NHW patients. Inpatient bleeding was more likely in Hispanic and NHOR patients but may not be related to receiving appropriate prophylaxis. NHOR patients were less likely to receive inpatient thromboprophylaxis.
RESUMO
BACKGROUND: Sleeve gastrectomy (SG) is an effective treatment option for patients with obesity. Robotic sleeve gastrectomy (RSG) is reported to have worse short-term patient outcomes compared to laparoscopic SG (LSG), but prior studies may not have accounted for evolving technology, including stapler utilization. OBJECTIVE: This study compared RSG and LSG outcomes over different time periods. SETTING: Academic Hospital. MATERIAL AND METHODS: The 2015 to 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project (MBSAQIP) databases were used. Matched cohort analyses compared adverse outcomes within 30 days for the 2015-2018 and 2019-2021 cohorts. Bivariate and regression models compared cohorts using Stata/MP 17.0. RESULTS: Seven hundred sixty-eight thousand and sixty-nine SG were analyzed. Over the 7-year study period, all patient outcomes, operation length (OL), and length of stay (LOS) trended downward for RSG, except surgical site infection (SSI). In the 2015-2018 cohort, leak was significantly higher with RSG (OR 1.53), and OL and LOS longer (p < 0.001). In the 2019-2021 cohort which corelated with a significant increase in robotic cases, leak (OR 1.36), SSI (OR 1.46), and morbidity (OR 1.11) were higher with RSG. While the mean difference in OL and LOS decreased between the two time periods, they remain longer for RSG (p < 0.001). CONCLUSION: While RSG and LSG are safe with similar mortality, RSG continues to be associated with higher rates of morbidity, leak, and SSI, as well as longer OL, hospital LOS, and higher cost. The study is limited by the ability to account for the impact of surgeon experience and stapler utilization on outcomes.

PURPOSE: To examine changes in obesity prevalence among US adults after the COVID-19 pandemic by level of stay-at-home order and sociodemographic characteristics. DESIGN: Quasi-experimental study using repeated cross-sectional data. SETTING: Behavioral Risk Factor Surveillance System (BRFSS). SAMPLE: Pooled data for US adults ages ≥26 years (n = 1,107,673) from BRFSS (2018-2021). MEASURES: States/territories were classified into three levels of stay-at-home order: none, advisory/only for persons at risk, or mandatory for all. Individual-level sociodemographic characteristics were self-reported. ANALYSIS: The difference-in-differences method was conducted with weighted multiple logistic regression analysis to examine obesity (body mass index ≥30 kg/m2) prevalence by stay-at-home order level and sociodemographic characteristics before/after the COVID-19 pandemic (January 2018-February 2020 vs March 2020-February 2022). RESULTS: After adjusting for a secular trend and multiple covariates, adults in states/territories with mandatory stay-at-home orders experienced a larger increase in obesity prevalence (adjusted odds ratio: 1.05; 95% confidence interval: 1.01, 1.11) than adults in states/territories with no stay-at-home order.

RESUMO
Are two adjacent genes in the same operon? What are the order and spacing between several transcription factor binding sites? Genome browsers are software data visualization and exploration tools that enable biologists to answer questions such as these. In this paper, we report on a major update to our browser, Genome Explorer, that provides nearly instantaneous scaling and traversing of a genome, enabling users to quickly and easily zoom into an area of interest. The user can rapidly move between scales that depict the entire genome, individual genes, and the sequence; Genome Explorer presents the most relevant detail and context for each scale. By downloading the data for the entire genome to the user's web browser and dynamically generating visualizations locally, we enable ï¬ne control of zoom and pan functions and real-time redrawing of the visualization, resulting in smoother and more intuitive exploration of a genome than is possible with other browsers. Further, genome features are presented together, in-line, using familiar graphical depictions. In contrast, many other browsers depict genome features using data tracks, which have low information density and can visually obscure the relative positions of features. Genome Explorer diagrams have a high information density that provides larger amounts of genome context and sequence information to be presented in a given-sized monitor than for tracks-based browsers. Genome Explorer provides optional data tracks for the analysis of large-scale data sets and a unique comparative mode that aligns genomes at orthologous genes with synchronized zooming. IMPORTANCE: Genome browsers provide graphical depictions of genome information to speed the uptake of complex genome data by scientists. They provide search operations to help scientists find information and zoom operations to enable scientists to view genome features at different resolutions. We introduce the Genome Explorer browser, which provides extremely fast zooming and panning of genome visualizations and displays with high information density.

Background: Four-factor prothrombin complex concentrate (PCC) is a plasma product that contains factors II, VII, IX, X, protein C, and protein S. PCC can be used off-label to treat coagulopathy during orthotopic liver transplantation (OLT). However, its use comes with safety concerns regarding thrombosis. The purpose of our study is to determine the safety of PCC in OLT. Methods: We conducted a retrospective cohort study of patients who received 4-factor PCC during OLT at our institution from January 1, 2018, to May 1, 2022, with a 1:1 match of 83 patients who received PCC and 83 patients who did not. We evaluated 30-d mortality, 1-y mortality, prevalence of thrombotic complications (portal vein thrombosis, deep venous thrombosis, myocardial infarction, and pulmonary embolus), and postoperative intensive care (ICU) length of stay (LOS). Results: There was no significant difference in 30-d mortality (odds ratio [OR] 5; 95% confidence interval [CI], 0.58-42.8; Pâ =â 0.14), 1-y mortality (OR 3; 95% CI, 0.61-14.86; P = 0.18), or ICU LOS (OR -13.8; 95% CI, -39.2 to 11.6; Pâ =â 0.29). There was no increased incidence of thrombotic complications among patients receiving PCC 90 d after surgery, including portal vein thrombosis (OR 1.5; 95% CI, 0.42-5.32; P = 0.53), pulmonary embolus (OR 1; 95% CI, 0.14-7.1; P = 0.99), deep venous thrombosis (OR 0.67; 95% CI, 0.11-3.99; P = 0.66), and myocardial infarction (OR 1.67; 95% CI, 0.4-6.97; P = 0.48). Conclusions: Although there was a statistically insignificant increase in mortality after PCC administration during OLT, we did not see a significant increase in perioperative complications, including thrombotic events and increased ICU LOS.
RESUMO
BACKGROUND: The benefits of prophylactic ureteral stent placement during colorectal surgery remain controversial. This study aimed to determine the incidence of ureteral injury in colorectal operations, assess the complications associated with stent usage, and determine whether their use leads to earlier identification and treatment of injury. METHODS: This was a retrospective study of patients undergoing colorectal abdominal operations between 2015 and 2021. Variables were examined for possible association with ureteral stent placement. The primary study endpoint was ureteral injury identified within 30 days postoperatively. RESULTS: Of 6481 patients who underwent colorectal surgery, 970 (15%) underwent preoperative ureteral stent placement. The use of stents was significantly associated with a higher American Society of Anesthesiologists classification, wound classification, and longer duration of surgery. A ureteral injury was identified in 28 patients (0.4%). Of these patients, 13 had no stent, and 15 had preoperative stents placed. After propensity matching, stent use was associated with an increased risk of hematuria and urinary tract infection. Ureteral injury was identified intraoperatively in 14 of 28 patients (50.0%) and was not associated with ureteral stent use (P = .45). CONCLUSION: Iatrogenic ureteral injury was uncommon, whereas preoperative stent placement was relatively frequent. Earlier recognition of iatrogenic ureteral injury is not an expected advantage of preoperative ureteral stent placement.

BACKGROUND: The complex interplay of the social determinants of health, race/ethnicity, and traditional surgical risk factors on outcomes following metabolic surgery is poorly understood. OBJECTIVE: To evaluate the relationship between the social determinants of health as measured by county health ranking (CHR) and short-term metabolic surgery outcomes. SETTING: Five accredited bariatric program sites at a national academic health system. METHODS: Data were collected from 5 sites of a single health system from 2010 to 2021. Current procedural terminology codes identified primary and revisional cases. Patient characteristics, procedural data, and 30-day occurrences were collected. CHRs for health factors were determined by ZIP Code and stratified into best, middle, and worst terciles. The primary outcome was 30-day complications, readmissions, or reinterventions/reoperations. Logistic regression assessed the correlation between CHR tercile and morbidity. RESULTS: We analyzed 4,315 primary and 370 revisional metabolic surgery cases. Overall, 64.0%, 27.4%, and 8.6% of patients lived in the best, middle, and worst CHR terciles, respectively. Patients in the middle and worst CHR terciles were more commonly older; non-Hispanic Black or Hispanic; suffered from preexisting chronic obstructive pulmonary disease or hypertension, were dialysis dependence, were on therapeutic anticoagulation, or had inferior vena cava filters. Middle and worst CHR tercile patients were more likely to undergo index sleeve gastrectomy or robotic-assisted surgery and have surgery performed by a self-designated general surgeon. Thirty-day outcomes were similar across CHR terciles. Racial disparity in multiple short-term outcomes persisted despite adjustment for CHR tercile. CONCLUSION: Higher-risk patients are more likely to be from counties with lower CHRs, but CHR was not independently associated with 30-day outcomes after metabolic surgery.
RESUMO
Objective: To evaluate prescribing practices for the anti-Xa reversal agent, andexanet alfa, to identify challenges in ordering and administering this medication, and to offer recommendations to improve patient safety. Patients and Methods: This retrospective study reviewed all adult patients treated with andexanet alfa (AA) at a single institution between January 1, 2018, and March 31, 2020. We identified ordering and administration benchmarks based on recommendations from previous clinical trials on AA. We then reviewed these medical records to determine compliance with these benchmarks. We also collected data related to thrombotic complications and mortality. Results: Twenty-two AA dosing sets (loading and infusion dose) were given to 20 patients. Eight (36%) dosing sets met our ordering benchmarks regarding appropriate dose, time since last direct oral anticoagulants, urgency of administration, and documentation. Three (14%) dosing sets met the administrative benchmarks of being started within 30 minutes of the initial order, and 13 (59%) dosing sets had timely infusion of the infusion dose after the loading dose. No dosing set met all our administration benchmarks. There was 1 thrombotic event within 24 hours of the correct AA dose and 1 potential death related to AA. Conclusion: This study highlights challenges in ordering and administering AA at our institution and brings awareness to potential similar concerns at other institutions. These challenges also identified the need for optimized order sets, a streamlined administration process, and frequent provider education to improve patient safety.
RESUMO
Objective: To determine associations of incident cancer diagnoses in women with recent emergency department (ED) care. Patients and Methods: A retrospective cohort study analyzing biological females aged 18 years and older, who were diagnosed with an incident primary cancer (12 cancer types studied) from January 1, 2015, to December 31, 2021, from electronic health records. The primary outcome was a cancer diagnosis within 6 months of a preceding ED visit. Secondary outcomes included patient factors associated with a preceding ED visit. Results: Of 25,736 patients (median age of 62 years, range 18-101) diagnosed with an incident primary cancer, 1938 (7.5%) had an ED visit ≤6 months before a diagnosis. The ED-associated cancer cases were highest in lung cancer (n=514, 14.7%) followed by acute lymphoblastic leukemia (n=22, 13.3%). Patient factors increasing the likelihood of ED evaluation before diagnosis included 18-50 years of age (OR=1.32; 95% CI, 1.09-1.61), Elixhauser score (measure of comorbidities) >4 (OR=17.90; 95% CI, 14.21-22.76), use of Medicaid or other government insurance (OR=2.10; 95% CI, 1.63-2.69), residence within the institutional catchment areas (OR=3.18; 95% CI, 2.78-3.66), non-Hispanic Black race/ethnicity (OR=1.41; 95% CI, 1.04-1.88), and established primary care provider at Mayo Clinic (OR=1.45; 95% CI, 1.28-1.65). The ED visits were more likely in those who died within 6 months of diagnosis (n=327, 37.8%) than those who did not die (n=1611, 6.5%). Conclusion: Patient characteristics identified in this study offer opportunities to provide cancer risk assessment and health navigation, particularly among individuals with comorbidities and limited health care access.
RESUMO
Background: Management of periprosthetic fractures has been guided by the Vancouver classification, which recommends revision for fractures around a loose femoral implant (B2). New studies have challenged this approach, demonstrating acceptable outcomes with internal fixation. This study evaluates our experience with Vancouver B2 fractures, comparing internal fixation to femoral revision. We hypothesized that in select cases with cementless stems, internal fixation would provide acceptable results with reduced morbidity. Methods: A retrospective review was performed of periprosthetic hip fractures treated at our institution between 1 January 2012 and 4 November 2022. We excluded patients who did not have prior radiographs and evidence of stem subsidence, suggestive of a Vancouver B2 fracture. Thirteen patients were included in the analysis. Results: Four patients (31%) underwent revision of the femoral component, 4 patients (31%) underwent plating, and 5 patients (38%) underwent internal fixation with cerclage cabling. The average operative duration was 158 minutes, 203 minutes, and 62 minutes for the revision, plating, and cabling cohorts, respectively (P = .009). Blood loss was 463 cc, 510 cc, and 90 cc for the revision, plating, and cabling cohorts, respectively (P = .036). Three patients in both the revision and plating cohorts each received a transfusion (75%), whereas no patients in the cabling cohort required a transfusion (P = .033). All patients demonstrated fracture healing on the postoperative radiographs. No patients required additional surgery during the follow-up period. Conclusions: We have demonstrated that Vancouver B2 periprosthetic fractures with intact lateral cortices may be treated with internal fixation with cerclage cabling with excellent results.
RESUMO
Background: Dexamethasone (DEX) has been shown to reduce pain and postoperative nausea and vomiting for patients undergoing elective total joint arthroplasty (TJA). We investigated the impact of DEX on glycemic control and outcomes in patients with type 2 diabetes mellitus undergoing elective primary TJA. Methods: All patients with type 2 diabetes mellitus undergoing primary elective TJA between January 2016 and December 2021 at 4 sites within 1 hospital system were identified. Propensity scores were calculated to match patients receiving or not receiving DEX. Primary outcomes were perioperative blood glucose levels and the incidence of hyperglycemia. Secondary outcomes were the amount of insulin administered, the occurrence of 30-day postoperative surgical site infections, hospital readmission, and mortality. Results: After matching, we identified 1372 patients. DEX administration was associated with a significant increase in mean blood glucose levels in mg/dL on postoperative days (PODs) 0 to 2: POD 0 (28.4, 95% confidence interval [CI]: 24.6-32.1), POD 1 (14.4, 95% CI: 10.1-18.8), POD 2 (12.4, 95% CI: 7.5-17.2) when comparing patients who did or did not receive DEX. Additionally, patients receiving DEX, compared to patients who did not receive DEX, had increased odds of experiencing hyperglycemia on POD 0 (odds ratio: 4.0, 95% CI: 3.1-5.2). DEX was not associated with a significant difference in insulin administration, surgical site infections, hospital readmission, or mortality. Conclusions: In our review of 1372 patients with propensity-matched type 2 diabetes mellitus undergoing elective, primary TJA, we found that DEX administration was associated with an increased risk of elevated mean glucose on POD 0-2, hyperglycemia on POD 0, but was not associated with an increase in total insulin dose administered nor occurrence of surgical site infections, hospital readmission, or mortality within 30 days of surgery in patients who received DEX compared to patients who did not receive DEX. Level of Evidence: IV.
