Abstract Background Surgical drains are routinely used following autologous reconstruction, but are often cited as the leading cause of peri-operative discomfort. This study defined routine drain use duration and assessed the risk factors for prolonged breast and abdominal drain use during microvascular breast reconstruction, measures which have never previously been defined. Methods Patients who underwent an abdominal microvascular free flap were included. Demographics, comorbidities, and operation-related characteristics were retrospectively collected in a prospectively maintained database. Statistical analysis utilized chi-square independent t-test, and linear regression analyses. Results One hundred forty-nine patients comprising 233 breast flaps were included. Average breast and abdominal drain duration were 12.9 ± 3.9 and 17.7 ± 8.2 days, respectively. Prolonged breast and abdominal drain duration were defined as drain use beyond the 75th percentile at 14 and 19 days, respectively. Multivariable regression revealed hypertension was associated with an increased breast drain duration by 1.4 days (p = 0.024), axillary dissection with 1.7 days (p = 0.026), African-American race with 3.1 days (p < 0.001), Hispanic race with 1.6 days (p = 0.029), return to the OR with 3.2 days (p = 0.004), and each point increase in BMI with 0.1 days (p = 0.028). For abdominal drains, each point increase in BMI was associated with an increased abdominal drain duration by 0.3 days (p = 0.011), infection with 14.4 days (p < 0.001), and return to the OR with 5.7 days (p = 0.007). Conclusion Elevated BMI, hypertension, and axillary dissection increase risk for prolonged breast drain requirement in autologous reconstruction. African-American and Hispanic populations experience prolonged breast drain requirement after controlling for other factors, warranting further study.

AbstractPeriviable infants (i.e., born before 26 complete weeks of gestation) represent fewer than .5% of births in the US but account for 40% of infant mortality and 20% of billed hospital obstetric costs. African American women contribute about 14% of live births in the US, but these include nearly a third of the country’s periviable births. Consistent with theory and with periviable births among other race/ethnicity groups, males predominate among African American periviable births in stressed populations. We test the hypothesis that the disparity in periviable male births among African American and non-Hispanic white populations responds to the African American unemployment rate because that indicator not only traces, but also contributes to, the prevalence of stress in the population. We use time-series methods that control for autocorrelation including secular trends, seasonality, and the tendency to remain elevated or depressed after high or low values. The racial disparity in male periviable birth increases by 4.45% for each percentage point increase in the unemployment rate of African Americans above its expected value. We infer that unemployment—a population stressor over which our institutions exercise considerable control—affects the disparity between African American and non-Hispanic white periviable births in the US.

Abstract Background Breast mound and nipple creation are the goals of the reconstructive process. Unlike in normal body mass index (BMI) women, breast reconstruction in the obese is associated with increased risk of perioperative complications. Our aim was to determine if reconstruction technique and the incidence of perioperative complications affect the achievement of reconstruction completion in the obese female. Methods Consecutive obese women (BMI ≥30) who underwent mastectomy and implant or autologous reconstruction were evaluated for the completion of breast reconstruction. Results Two hundred twenty-five women with 352 reconstructions were included. Seventy-four women underwent 111 autologous reconstructions and 151 women underwent 241 implant-based reconstructions. Chemotherapy, radiation, and delayed reconstruction timing was more common in the autologous patients. Major perioperative complications (requiring hospital readmission or unplanned surgery) occurred more frequently in the implant group (p ≤ 0.0001). Breast mounds were completed in >98% of autologous cases compared with 76% of implant cases (p ≤ 0.001). Nipple areolar complex (NAC) creation was completed in 57% of autologous patients and 33% of implant patients (p = 0.0009). The rate of successfully completing the breast mound and the NAC was higher in the autologous patient group (Mound odds ratio or OR 3.32, 95% confidence interval or CI 1.36–5.28 and NAC OR 2.7, 95% CI 1.50–4.69). Conclusion Occurrence of a major complication in the implant group decreased the rate of reconstruction completion. Obese women who undergo autologous breast reconstruction are more likely to achieve breast reconstruction completion when compared with obese women who undergo implant-based breast reconstruction.

Objective.Juvenile idiopathic arthritis (JIA) affects children of all races. Prior studies suggest that phenotypic features of JIA in African American (AA) children differ from those of non-Hispanic white (NHW) children. We evaluated the phenotypic differences at presentation between AA and NHW children enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry, and replicated the findings in a JIA cohort from a large center in the southeastern United States.Methods.Children with JIA enrolled in the multicenter CARRA Registry and from Emory University formed the study and replication cohorts. Phenotypic data on non-Hispanic AA children were compared with NHW children with JIA using the chi-square test, Fisher’s exact test, and the Wilcoxon signed-rank test.Results.In all, 4177 NHW and 292 AA JIA cases from the CARRA Registry and 212 NHW and 71 AA cases from Emory were analyzed. AA subjects more often had rheumatoid factor (RF)-positive polyarthritis in both the CARRA (13.4% vs 4.7%, p = 5.3 × 10−7) and the Emory (26.8% vs 6.1%, p = 1.1 × 10−5) cohorts. AA children had positive tests for RF and cyclic citrullinated peptide antibodies (CCP) more frequently, but oligoarticular or early onset antinuclear antibody (ANA)-positive JIA less frequently in both cohorts. AA children were older at onset in both cohorts and this difference persisted after excluding RF-positive polyarthritis in the CARRA Registry (median age 8.5 vs 5.0 yrs, p = 1.4 × 10−8).Conclusion.Compared with NHW children, AA children with JIA are more likely to have RF/CCP-positive polyarthritis, are older at disease onset, and less likely to have oligoarticular or ANA-positive, early-onset JIA, suggesting that the JIA phenotype is different in AA children.

The Relationship

489 Background: Immune checkpoint inhibition (ICI) has greatly improved clinical outcomes for pts with mUC and other cancers. ICI is associated with a class of AEs, deemed irAEs due to immune activation. Nonetheless, biomarkers associated with irAE are still lacking. We hypothesized that the immune response against neoantigens is partly responsible for irAEs and investigated the association between irAEs, TMB and response to ICI. Methods: We identified patients with mUC at Dana Farber Cancer Institute who were treated with ICI (monotherapy or combination) and had available tumor sequencing data through Oncopanel. TMB was calculated using the number of non-synonymous exonic mutations per megabase. The severity of irAEs was graded using CTCAE v.5.0. Mann-Whitney U test was performed to identify association between TMB, incidence and grade of irAEs. A cut-off of 10/mb was assigned for TMB. Fisher’s exact test was used to evaluate the radiologic response between pts with and without irAEs and low vs. high TMB. Multivariable linear regression was used to assess the relationship between TMB, irAEs and response. p-values were adjusted using Benjamini-Hochberg method. Results: Of 101 pts with mUC who met the inclusion criteria, 32 (32%) reported irAEs. 6 (6%) were grade (G)1, 20 (20%) were G2, and 6 (6%) were G3. Median(m) time on therapy was 84 days for pts without irAEs and 88 days for pts with irAEs. Pts with irAEs had higher mTMB (15.4/mb) compared to pts with no irAEs (9.8) ( p = 0.01). In pts on monotherapy (93), those with irAEs (n=27) had a higher mTMB (15.13/mb) compared to pts with no irAEs (n=66) (mTMB = 10.20/mb) ( p = 0.01). Out of 94 pts with radiological data, response was achieved in 16 (50%) pts with irAE vs 10 (16%) pts with no irAE ( p < 0.001). When both irAE and response were included in a multivariable regression, the association between irAE and TMB was not significant ( p = 0.4). Pts with both irAE and high TMB had a response rate of 56% which was significantly higher than those with either irAE but low TMB (28.6%) or high TMB but no irAE (21.2 %) or low TMB and no irAE (10.3%) (Chi-square test p = 0.002; FDR corrected p-values for individual comparisons in Table). There was no association between TMB and irAE grade. Conclusions: Higher TMB was associated with higher incidence of irAEs in pts with mUC on ICIs. Moreover, pts with both high TMB and irAEs exhibited better response rates than those with only high TMB or irAEs, suggesting that they may provide complementary tumor and host characteristics. Further evaluation in mUC is needed to confirm this relationship between TMB, irAEs and response in a larger cohort and explore specific mutational signatures that may be associated with irAEs.

Introduction: The increasing prevalence of obesity in patients with breast cancer has prompted a reappraisal of the role of the latissimus dorsi flap (LDF) in breast reconstruction. Although the reliability of this flap in obese patients is well-documented, it is unclear whether sufficient volume can be achieved through a purely autologous reconstruction (eg, extended harvest of the subfascial fat layer). Additionally, the traditional combined autologous and prosthetic approach (LDF + expander/implant) is subject to increased implant-related complication rates related to flap thickness in obese patients. The purpose of this study is to provide data on the thicknesses of the various components of the latissimus flap and discuss the implications for breast reconstruction in patients with increasing body mass index (BMI). Methods: Measurements of back thickness in the usual donor site area of an LDF were obtained in 518 patients undergoing prone computed tomography–guided lung biopsies. Thicknesses of the soft tissue overall and of individual layers (e.g., muscle, subfascial fat) were obtained. Patient, demographics including age, gender, and BMI were obtained. Results: A range of BMI from 15.7 to 65.7 was observed. In females, total back thickness (skin, fat, muscle) ranged from 0.6 to 9.4 cm. Every 1-point increase in BMI resulted in an increase of flap thickness by 1.11 mm (adjusted R 2 of 0.682, P < .001) and an increase in the thickness of the subfascial fat layer by 0.513 mm (adjusted R 2 of 0.553, P < .001). Mean total thicknesses for each weight category were 1.0, 1.7, 2.4, 3.0, 3.6, and 4.5 cm in underweight, normal weight, overweight, and class I, II, III obese individuals, respectively. The average contribution of the subfascial fat layer to flap thickness was 8.2 mm (32%) overall and 3.4 mm (21%), 6.7 mm (29%), 9.0 mm (30%), 11.1 mm (32%), and 15.6 mm (35%) in normal weight, overweight, class I, II, III obese individuals, respectively. Conclusion: The above findings demonstrate that the thickness of the LDF overall and of the subfascial layer closely correlated with BMI. The contribution of the subfascial layer to overall flap thickness tends to increase as a percentage of overall flap thickness with increasing BMI, which is favourable for extended LDF harvests. Because this layer cannot be separated from overall thickness on examination, these results are useful in estimating the amount of additional volume obtained from an extended latissimus harvest technique.

Abstract Background Inflammatory bowel diseases (IBD), like ulcerative colitis (UC) and Crohn’s disease (CD), are associated with urinary extra-intestinal manifestations, like urolithiasis and uncomplicated urinary tract infections (UTIs). The literature reviewed for this study identifies an increased association of CD and urolithiasis against the general population as well as UC. Furthermore, the rates in which urinary comorbidities manifest have not been well characterized in cross-race analyses. The purpose of this study is to establish the prevalence of common urinary extra-intestinal manifestations in CD and UC and to further determine at what rate these affect the African American and Caucasian populations. Methodology This is a retrospective cohort study using de-identified data collected from a research data base that included 6 integrated facilities associated with one tertiary healthcare center from 2012 to 2019. The electronic chart records for 3104 Caucasian and African American IBD patients were reviewed for frequency of urolithiasis and uncomplicated UTI via diagnosed ICD-10 codes. Comparison between data groups was made using multivariate regressions, t-tests, and chi square tests. Results Our study included 3104 patients of which 59% were female, 38% were African American, and 43% were diagnosed with UC. Similar proportions of UC and CD diagnosed patients developed urolithiasis (6.0% vs 6.7%, p = 0.46), as well as uncomplicated UTIs (15.6% vs. 14.9%, p = 0.56). Similar proportions of African American and Caucasian patients developed urolithiasis (5.4% vs 7.0%, p = 0.09), but a higher proportion of African Americans developed uncomplicated UTIs (19.4% vs 12.6%, p ≤ 0.001). Conclusion We found similar rates of urolithiasis formation in both UC and CD in this study. Furthermore, these rates were not significantly different between African American and Caucasian IBD populations. This suggests that UC patients have an elevated risk of urolithiasis formation as those patients with CD. Additionally, African Americans with IBD have a higher frequency of uncomplicated UTI as compared to their Caucasian counterparts.

Background: Heart failure (HF) admissions are frequent and result in significant expenditures. Identifying predictors of increased length of stay (LOS), particularly above the median LOS, may help providers set expectations for patients and target resources effectively. Methods: We analyzed HF admissions (n= 70,094) from January 2005 through April 2007 from 246 hospitals in the AHA's Get With The Guidelines-HF program. In a subset with BNP (n=44,535), baseline characteristics, admission vital signs and selected labs (BNP, creatinine, BUN, hemoglobin, and sodium) were included in a multivariable regression analysis to determine factors associated with LOS ≥4 days. Results: Patients were median age of 72, 45% female, 53% had ischemic etiology, and median LVEF was 35%. Median LOS was 4 days (25 th ,75 th 2,6). The most significant predictors of LOS ≥ 4 days were a higher admission BUN, higher heart rate, and lower SBP (Table 1). Age, insurance, race, creatinine, and LVEF were not. Conclusion: Upon admission for HF, certain vital signs, comorbidites, and laboratory values are associated with an increased likelihood of a LOS ≥ 4 days. These observations may be of value in the implementation of interventions aimed at reducing LOS and improving quality of care in HF.

Abstract Background In delayed breast reconstruction, the thoraco-mammary cutaneous tissue often shows residual damage from radiotherapy. The fragility of this tissue is associated with a risk of skin necroses of about 8% when dissection is performed by reopening of the mastectomy scar. Objectives The objective of our study was to adapt the technique of short-scar latissimus dorsi flap surgery with an abdominal advancement flap using a lateral approach only avoiding re-incision of the mastectomy scar. Methods In this retrospective study, we performed 150 reconstructions in 146 patients to assess the safety and effectiveness of the SSLD technique with lateral approach. The primary outcome was the occurrence of postoperative skin necrosis of the thoraco-mammary area. Results Of the 150 delayed breast reconstruction procedures performed, none showed skin necrosis of the thoraco-mammary area, and a positive effect on skin trophicity of this area was observed. The resulting patient and surgical team satisfaction were very favorable. Conclusions In our practice, this technique changed our paradigm because of good skin safety and effectiveness. It allows reconstruction without a patch-effect in patients with very poor skin quality in whom the thoraco-mammary skin would have been replaced in the past by a skin paddle. Reconstruction would have even be contraindicated. It could also be an alternative to many other more complex and longer techniques of autologous reconstruction.

Background: Post-interventional cerebral hyperdensities (PCHD) are present 31.2 to 87.5% of the time on post-thrombectomy (PT) CT. It can be difficult for radiologists to differentiate if PCHD represents intracerebral hemorrhage (ICH) or contrast staining using conventional CT. The ability to accurately determine the etiology of PCHD may be important for a patient’s outcome. Methods: We retrospectively investigated clinical risk factors, imaging findings, and interventional technique of patients who had a thrombectomy from 2011-2017 (n=238) at a Comprehensive Stroke Center. 112 patients with anterior circulation infarcts and immediate PT CTs as well as either a PT MRI or follow-up CT within 48 hours were included. Two experienced neuroradiologists interpreted all imaging. Baseline demographics and imaging characteristics were collected. The presence of ICH was determined by dephasing on gradient echo or by its persistence > 2 days on repeat CT. Chi-square and Fisher’s exact tests were used for statistical significance, and logistic regression to determine risk estimates. Results: 84% of patients had PCHD, of which 56% had ICH. Patients had similar demographics (ICH: median age 69, 47.5% female; non-ICH: median age 71, 42.5% female). Higher pre-thrombectomy ASPECTS score (OR 0.62, p < 0.05) decreased the risk of ICH, and higher Hounsfield units (HU) of PCHD both on immediate (OR 1.04, p < 0.05) and intermediate (OR 1.1, p < 0.0005) PT CT increased the risk of ICH. PCHDs in the deep grey matter (OR 2.84, p < 0.05) and demonstrating a confluent pattern (OR 3.9 p < 0.05) increased the likelihood of ICH. 10% increase risk of ICH was seen for every HU increase in density on PT CT at 24 or 48 hours. A 50% decrease in ICH was observed for each unit increase of the pre-thrombectomy ASPECTS score. ROC revealed the optimal cut-off for predicted probability as 0.64, sensitivity 70.2% and specificity 69.2%. The AUC for the predicted model was 0.84 (95%CI= (0.75- 0.92, p <0.0001). Conclusion: Several imaging characteristics of PCHDs and ASPECTS score can help differentiate between the PT ICH and contrast staining. Application of these variables to patients in the immediate PT period may change clinical management.
