Abstract
This case report follows a 66-year-old female who originally presented with malignant melanoma in the left knee and recurrence in the left inguinal region. This prompted a whole body FDG PET/CT scan which showed incidental focal hypermetabolism in the uterus. The diagnosis of endometrial cancer was confirmed at biopsy, and the patient was treated with total abdominal hysterectomy. Melanoma patients are at increased risk of second primary malignancy, and endometrial cancer is a common second primary often diagnosed in cancer survivors. Incidental endometrial focal hypermetabolism should be investigated further for a synchronous malignancy, especially in a post-menopausal woman.

Abstract
The oral cavity, a unique ecosystem harboring diverse microorganisms, maintains health through a balanced microflora. Disruption may lead to disease, emphasizing the protective role of gingival epithelial cells (GECs) in preventing harm from pathogenic oral microbes. Shifting GECs' response from proinflammatory to antimicrobial could be a novel strategy for periodontitis. Photobiomodulation therapy (PBMT), a nonpharmacologic host modulatory approach, is considered an alternative to drugs. While the host cell response induced by a single type of pathogen-associated molecular patterns (PAMPs) was widely studied, this model does not address the cellular response to intact microbes that exhibit multiple PAMPs that might modulate the response. Inspired by this, we developed an in vitro model that simulates direct interactions between host cells and intact pathogens and evaluated the effect of PBMT on the response of human gingival keratinocytes (HGKs) to challenge viable oral microbes at both the cellular and molecular levels. Our data demonstrated that LED pretreatment on microbially challenged HGKs with specific continuous wavelengths (red: 615 nm; near-infrared: 880 nm) induced the production of various antimicrobial peptides, enhanced cell viability and proliferation, promoted reactive oxygen species scavenging, and down-modulated proinflammatory activity. The data also suggest a potential explanation regarding the superior efficacy of near-infrared light treatment compared with red light in enhancing antimicrobial activity and reducing cellular inflammation of HGKs. Taken together, the findings suggest that PBMT enhances the overall barrier function of gingival epithelium while minimizing inflammation-mediated breakdown of the underlying structures.

Abstract
BACKGROUND Multivisceral resection of retroperitoneal liposarcoma (LPS) is associated with increased morbidity and may not confer a survival benefit compared with tumor-only (TO) resection. We compared both approaches using a novel statistical method called the "win ratio" (WR). METHODS Patients who underwent resection of LPS from 2004 to 2015 were identified from the National Cancer Database. Multivisceral resection was defined as removal of the primary site in addition to other organs. The WR was calculated based on a hierarchy of postoperative outcomes: 30-day and 90-day mortality, long-term survival, and severe complication. RESULTS Among 958 patients (multivisceral 634, TO 324) who underwent resection, the median age was 63 years (interquartile range [IQR] 54-71) with a median follow-up of 51 months (IQR 30-86). There was no difference in the WR among patients who underwent TO versus multivisceral resection in the matched cohort (WR 0.82, 95% confidence interval [CI] 0.61-1.10). In patients aged 72-90 years, those who underwent multivisceral resection had 36% lower odds of winning compared with patients undergoing TO resection (WR 0.64, 95% CI 0.40-0.98). A subgroup analysis of patients classified as not having adjacent tumor involvement at the time of surgery revealed that those patients who underwent multivisceral resection had 33% lower odds of winning compared to TO resection (WR 0.67, 95% CI 0.45-0.99). CONCLUSIONS Based on win-ratio assessments of a hierarchical composite endpoint, multivisceral resection in patients without adjacent tumor involvement may not confer improved outcomes. This method supports the rationale for less invasive resection of LPS in select patients, especially older patients.

Abstract
BACKGROUND While surgery is generally necessary for most solid-organ cancers, curative-intent resection is occasionally aborted due to unanticipated unresectability or occult metastases. Following aborted cancer surgery (ACS), patients have unique and complex care needs and yet little is known about the optimal approach to their management. OBJECTIVE The aim of this study was to define the practice patterns and perspectives of an international cohort of cancer surgeons on the management of ACS. METHODS A validated survey assessing surgeon perspectives on patient care needs and management following ACS was developed. The survey was distributed electronically to members of the Society of Surgical Oncology (SSO). RESULTS Among 190 participating surgeons, mean age was 49 ± 11 years, 69% were male, 61% worked at an academic institution, and most had a clinical practice focused on liver/pancreas (30%), breast (23%), or melanoma/sarcoma cancers (20%). Participants estimated that ACS occurred in 7 ± 6% of their cancer operations, most often due to occult metastases (67%) or local unresectability (30%). Most surgeons felt (very) comfortable addressing their patients' surgical needs (92%) and cancer treatment-related questions (90%), but fewer expressed comfort addressing psychosocial needs (83%) or symptom-control needs (69%). While they perceived discussing next available therapies as the patients' most important priority after ACS, surgeons reported avoiding postoperative complications as their most important priority (p < 0.001). While 61% and 27% reported utilizing palliative care and psychosocial oncology, respectively, in these situations, 46% noted care coordination as a barrier to addressing patient care needs. CONCLUSIONS Results from this SSO member survey suggest that ACS is relatively common and associated with unique patient care needs. Surgeons may feel less comfortable assessing psychosocial and symptom-control needs, highlighting the need for novel patient-centered approaches.

Abstract
BACKGROUND Surgery and radiation therapy remain the standard of care for patients with high-grade extremity soft tissue sarcoma that are >5 cm. Radiation therapy is time and labor-intensive for patients, and social determinants of health may affect adherence. The aim of this study was to define demographic, clinical, and treatment factors associated with the completion of radiation therapy and determine if preoperative radiation therapy improved adherence compared to postoperative radiation therapy. METHODS The cohort included patients in the National Cancer Database with high-grade extremity soft tissue sarcoma >5 cm without nodal or distant metastases who received limb-sparing surgery and radiation therapy with microscopically negative R0 margins. Multivariable logistic regression analyses identified factors associated with radiation therapy sequencing and adherence (defined as completion of 50 Gy preoperative radiation therapy or at least 60 Gy postoperative radiation therapy). A multivariable Cox Proportional Hazards model assessed overall survival. RESULTS Among 2,145 patients, 47.1% received preoperative radiation therapy (n = 1,010), and 52.9% (n = 1135) received postoperative radiation therapy. A greater proportion of patients treated with preoperative (77.2%) versus postoperative radiation therapy (64.9%, P < .0001) received the recommended dose. More patients with private insurance (49.8% vs 35.3% Medicaid vs 44.9% Medicare, P = .011) and patients treated at an academic medical center (52.6% vs 47.4%, P < .001) received preoperative radiation therapy. Patients who received preoperative radiation therapy had lower odds of receiving insufficient doses of radiation therapy (odds ratio 0.34 [95% CI 0.27-0.47]). Neither radiation therapy adherence nor sequencing were independent predictors of overall survival. CONCLUSIONS Patients who received preoperative radiation therapy were more likely to complete therapy and receive an optimal dose than patients treated with postoperative radiation therapy. Preoperative radiation therapy improves adherence and should be widely considered in patients with high-grade extremity soft tissue sarcoma, particularly in patients at risk for not completing therapy.

Abstract
BACKGROUND Allostatic load (AL) is a biological measure of cumulative exposure to socioenvironmental stressors (e.g., poverty). This study aims to examine the association between allostatic load (AL) and postoperative complications (POC) among patients with breast cancer. METHODS Assigned females at birth ages 18 + with stage I-III breast cancer who received surgical management between 01/01/2012-12/31/2020 were identified in the Ohio State Cancer registry. The composite AL measure included biomarkers from the cardiovascular, metabolic, immune, and renal systems. High AL was defined as composite scores greater than the cohort's median (2.0). POC within 30 days of surgery were examined. Univariable and multivariable regression analysis examined the association between AL and POC. RESULTS Among 4,459 patients, 8.2% had POC. A higher percentage of patients with POC were unpartnered (POC 44.7% vs no POC 35.5%), government-insured (POC 48.2% vs no POC 38.3%) and had multiple comorbidities (POC 32% vs no POC 20%). Patients who developed POC were more likely to have undergone sentinel lymph node biopsy followed by axillary lymph node dissection (POC 51.2% vs no POC 44.6%). High AL was associated with 29% higher odds of POC (aOR 1.29, 95% CI 1.01-1.63). A one-point increase in AL was associated with 8% higher odds of POC (aOR 1.08, 95% CI 1.02-1.16) and a quartile increase in AL was associated with 13% increased odds of POC (aOR 1.13, 95% CI 1.01-1.26). CONCLUSION Among patients undergoing breast cancer surgery, increased exposure to adverse socioenvironmental stressors, operationalized as AL, was associated with higher odds of postoperative complications.

Abstract
BACKGROUND Based on the NCCN Guidelines for Soft Tissue Sarcoma (STS), treatment of extremity STS (ESTS) includes radiation therapy (RT) and surgical resection for tumors that are high-grade and >5 cm. The aim of this study was to describe the association between neighborhood socioeconomic status (nSES), concordance with NCCN Guidelines recommendations, and outcomes in patients with ESTS. METHODS Patients with ESTS diagnosed from 2006 through 2018 were identified in SEER registries. The analytic cohort was restricted to patients with high-grade tumors >5 cm without nodal or distant metastases who received limb-sparing surgery. Patient demographics and tumor characteristics associated with receipt of RT were analyzed using adjusted regression analyses. Kaplan-Meier curves and adjusted accelerated failure time models were used to examine disparities in cancer-specific survival. RESULTS Of 2,249 patients, 29.0% (n=648) received neoadjuvant RT, 49.7% (n=1,111) received adjuvant or intraoperative RT, and 21.3% (n=476) did not receive RT. In adjusted analyses, lower nSES was associated with lower likelihood of receiving RT (odds ratio, 0.70 [95% CI, 0.57-0.87]; P<.001). Low nSES was associated with worse cancer-specific survival (hazard ratio, 1.19 [95% CI, 1.01-1.40]; P=.04). Race and ethnicity were not significant predictors of receipt of RT or cancer-specific survival in the fully adjusted models. CONCLUSIONS Patients from lower nSES areas were less likely to receive NCCN Guideline-recommended RT for their ESTS and had worse cancer-specific survival. Efforts to better define and resolve disparities in the treatment and survival of patients with ESTS are warranted.

Abstract
Nearly seventy percent of diagnostic lab test errors occur due to variability in preanalytical factors. 1-4 These are the parameters involved with all aspects of tissue processing, starting from the time tissue is collected from the patient in the operating room, until it is received and tested in the laboratory. While there are several protocols for transporting fixed tissue, organs, and liquid biopsies, such protocols are lacking for transport and handling of live solid tumor tissue specimens. There is a critical need to establish preanalytical protocols to reduce variability in biospecimen integrity and improve diagnostics for personalized medicine. 2,5 Here, we provide a comprehensive protocol for the standard collection, handling, packaging, cold-chain logistics, and receipt of solid tumor tissue biospecimens to preserve tissue viability.

Abstract
INTRODUCTION In the USA, approximately half of newly diagnosed patients with GC are 75 years or older. The objective of the current population-based study was to investigate the impact of neoadjuvant chemotherapy (NAC) on the outcomes of elderly patients with locally advanced GC. PATIENTS AND METHODS Patients aged > 75 years were identified from the National Cancer Database (NCDB). The primary outcome of the study was overall survival (OS). Secondary outcomes included lymph node (LN) harvest, surgical margin status, and 30-day mortality. To minimize the effect of selection bias on the assessed outcome between the two study groups (NAC versus no NAC), propensity score matching (PSM) was performed. RESULTS After PSM, a total of 1958 patients were included in both groups. NAC utilization increased from 2013 to 2019 (21% versus 42.7%, ptrend < 0.001). On pathologic analysis, patients who received NAC were more likely to have ≥ 16 LNs evaluated (NAC 60.1% versus no NAC 55.5%, p = 0.044) and negative resection margins (NAC 88.6% versus no NAC 83%, p = 0.001). Patients who received NAC were also less likely to experience 30-day mortality following resection (NAC 4.1% versus no NAC 7.1%). Receipt of NAC was associated with improved 1-year (73.9% versus 68.3%), 3-year (48.2% versus 43.5%), and 5-year OS (36.9% versus 30.5%) compared with patients who underwent upfront surgery (p = 0.01). CONCLUSIONS Receipt of NAC was associated with improved oncological outcomes among elderly patients undergoing resection for locally advanced GC.

Abstract
BACKGROUND AND AIMS Metabolic dysfunction-associated steatohepatitis (MASH) fibrosis is a reversible stage of liver disease accompanied by inflammatory cell infiltration. Neutrophils extrude a meshwork of chromatin fibers to establish neutrophil extracellular traps (NETs), which play important roles in inflammatory response regulation. Our previous work demonstrated that NETs promote HCC in MASH. However, it is still unknown if NETs play a role in the molecular mechanisms of liver fibrosis. APPROACH AND RESULTS Following 12 weeks of Western diet/carbon tetrachloride, MASH fibrosis was identified in C57BL/6 mice with increased NET formation. However, NET depletion using DNase I treatment or mice knocked out for peptidyl arginine deaminase type IV significantly attenuated the development of MASH fibrosis. NETs were demonstrated to induce HSCs activation, proliferation, and migration through augmented mitochondrial and aerobic glycolysis to provide additional bioenergetic and biosynthetic supplies. Metabolomic analysis revealed markedly an altered metabolic profile upon NET stimulation of HSCs that were dependent on arachidonic acid metabolism. Mechanistically, NET stimulation of toll-like receptor 3 induced cyclooxygenase-2 activation and prostaglandin E2 production with subsequent HSC activation and liver fibrosis. Inhibiting cyclooxygenase-2 with celecoxib reduced fibrosis in our MASH model. CONCLUSIONS Our findings implicate NETs playing a critical role in the development of MASH hepatic fibrosis by inducing metabolic reprogramming of HSCs through the toll-like receptor 3/cyclooxygenase-2/cyclooxygenase-2 pathway. Therefore, NET inhibition may represent an attractive treatment target for MASH liver fibrosis.

Abstract
The ETS transcription factor ERG is a master regulator of endothelial gene specificity and highly enriched in the capillary, vein, and arterial endothelial cells. ERG expression is critical for endothelial barrier function, permeability, and vascular inflammation. A dysfunctional vascular endothelial ERG has been shown to impair lung capillary homeostasis, contributing to pulmonary fibrosis as previously observed in IPF lungs. Our preliminary observations indicate that lymphatic endothelial cells (LEC) in the human IPF lung also lack ERG. To understand the role of ERG in pulmonary LECs, we developed LEC-specific inducible Erg-CKO and Erg-GFP-CKO conditional knockout (CKO) mice under Prox1 promoter. Whole lung microarray analysis, flow cytometry, and qPCR confirmed an inflammatory and pro-lymphvasculogenic predisposition in Erg-CKO lung. FITC-Dextran tracing analysis showed an increased pulmonary interstitial lymphatic fluid transport from the lung to the axial lymph node. Single-cell transcriptomics confirmed that genes associated with cell junction integrity were downregulated in Erg-CKO pre-collector and collector LECs. Integrating Single-cell transcriptomics and CellChatDB helped identify LEC specific communication pathways contributing to pulmonary inflammation, trans-endothelial migration, inflammation, and Endo-MT in Erg-CKO lung. Our findings suggest that downregulation of lymphatic Erg crucially affects LEC function, LEC permeability, pulmonary LEC communication pathways and lymphatic transcriptomics.

Abstract
INTRODUCTION We explored the association between weekend discharge and 30- and 90-d readmission rates in patients undergoing hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for peritoneal carcinomatosis. METHODS The US HIPEC Collaborative database, comprised of a longitudinal cohort of patients undergoing CRS/HIPEC for peritoneal carcinomatosis at twelve academic institutions between 2000 and 2017, was queried for date of discharge information. Patients were retrospectively divided into weekday and weekend/holiday discharge groups. Patients <18 y old, lacking day of discharge information, or who experienced intraoperative/in-hospital mortality were excluded. Comparisons were made between patients discharged on a weekday versus those discharged on a weekend or major holiday. RESULTS 1415 patients met inclusion criteria for the study: 1108 (78%) patients with a weekday discharge and 308 (22%) with a weekend/holiday discharge. Median age at time of surgery was 55 y (Interquartile Range: 46-63); 59% (n = 841) patients were female, 25% (n = 328) of patients had high volume disease (defined as a peritoneal cancer index >20 intraoperatively), and 92% (n = 1210) of patients had a complete cytoreduction (defined as a completeness of cytoreduction score of 0 or 1). Overall, 15% (n = 218) of patients were readmitted within 30 d and 19% (n = 265) within 90 d. In a linear mixed effects model, weekend discharge was not associated with higher 30- or 90-d readmissions (P = 0.291, P = 0.743). CONCLUSIONS Weekend discharges are safe following CRS/HIPEC. Length of stay initiatives should focus on discharging the patient when medically ready, rather than avoiding weekend discharge out of an abundance of caution.

Abstract
ABSTRACT A 50-year-old woman with history of metastatic neuroendocrine tumor underwent a follow-up PET/CT with 68 Ga-DOTATATE. An enlarged uterus with diffuse increased uptake warranted further investigation with an MRI that showed mass-like thickening of the endometrium, T2 hyperintensity, lobulated contour, and invasion of more than 50% of the myometrium. Biopsy revealed endometrial carcinoma with mucinous features. Mild to moderate uptake of the 68 Ga-DOTATATE by the uterus can be a normal physiological finding; however, it should prompt further investigation, particularly in a postmenopausal woman with concerning imaging or clinical findings.

Abstract
OBJECTIVE We sought to define the impact of community privilege on variations in travel patterns and access to care at high-volume hospitals for complex surgical procedures. BACKGROUND With increased emphasis on centralization of high-risk surgery, social determinants of health play a critical role in preventing equitable access to care. Privilege is a right, benefit, advantage, or opportunity that positively impacts all social determinants of health. METHODS The California Office of State-wide Health Planning Database identified patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PA), or proctectomy (PR) for a malignant diagnosis between 2012 and 2016 and was merged using ZIP codes with the Index of Concentration of Extremes, a validated metric of both spatial polarization and privilege obtained from the American Community Survey. Clustered multivariable regression was performed to assess the probability of undergoing care at a high-volume center, bypassing the nearest and high-volume center, and total real driving time and travel distance. RESULTS Among 25,070 patients who underwent a complex oncologic operation (ES: n=1216, 4.9%; PN: n=13,247, 52.8%; PD: n=3559, 14.2%; PR: n=7048, 28.1%), 5019 (20.0%) individuals resided in areas with the highest privilege (i.e., White, high-income homogeneity), whereas 4994 (19.9%) individuals resided in areas of the lowest privilege (i.e., Black, low-income homogeneity). Median travel distance was 33.1 miles (interquartile range 14.4-72.2). Roughly, three-quarters of patients (overall: 74.8%, ES: 35.0%; PN: 74.3%; PD: 75.2%; PR: 82.2%) sought surgical care at a high-volume center. On multivariable regression, patients residing in the least advantaged communities were less likely to undergo surgery at a high-volume hospital (overall: odds ratio 0.65, 95% CI 0.52-0.81). Of note, individuals in the least privileged areas had longer travel distances (28.5 miles, 95% CI 21.2-35.8) to reach the destination facility, as well as over 70% greater odds of bypassing a high-volume hospital to undergo surgical care at a low-volume center (odds ratio 1.74, 95% CI 1.29-2.34) versus individuals living in the highest privileged areas. CONCLUSIONS AND RELEVANCE Privilege had a marked effect on access to complex oncologic surgical care at high-volume centers. These data highlight the need to focus on privilege as a key social determinant of health that influences patient access to and utilization of health care resources.

Abstract
PURPOSE/OBJECTIVE(S) This study aimed to assess the ability of the number of positive lymph nodes (LNP) after neoadjuvant chemotherapy (NAC) to stratify prognosis even within the same ypN stage in breast cancer patients. MATERIALS/METHODS A 6,443 non-metastatic breast cancer patients with ypN1 disease after NAC following primary surgery were identified using the stage, stage evaluation field, treatment fields from Surveillance Epidemiology and End Results (SEER) database. Survival analysis was performed for overall survival (OS) using Kaplan-Meier plot and Cox proportional hazard models. RESULTS Of patients, 1,132(17.6%) had 3 positive lymph nodes (LNP3), 4,363 (67.7%) patients were T1/2 stage and 538 (8.35%) patients were downstage after treatment. LNP3 group had a significantly worse OS than LNP1/2 group (5yr OS, 74.2% vs. 80.9%, p <0.001). Similar results were observed in cause specific survival analysis (5yr OS, 79.8% vs. 85.2%, p <0.001). In subgroup analysis, there was a significant difference in OS between LNP1/2 and LNP3 group for HER2 or triple negative subtype, (p <0.001), T1/2 stage (p <0.001) and stable/downstage of N stage (p <0.001 and 0.019, respectively), but not for luminal A/B subtype and T3/4 (p = 0.126, 0.629 and 0.154, respectively). Regarding the number of examined lymph node (LNE), OS was significantly decreased in patients with LNE ≤5 in LNP3 group (p <0.001) but not in LNP1/2 group. In multivariable analysis, the prognostic significance of LNP3 remained (p <0.001) and the following factors were significantly related to the prolonged OS; Luminal A/B (p<0.001 and 0.001, respectively), T1/2 stage (p <0.001), N1 stage (p <0.001), LNE (≤5 vs. >5, p = 0.001) and receipt of radiotherapy (p = 0.012). Even when PS matching was performed, the OS of LNP was worse than that of LNP1/2. CONCLUSION LNP could more stratify the patients with ypN1 breast cancer after NAC. LNP3 is significantly associated with OS even after adjusting for other prognosticators. In particular, since there is a potential difference in the magnitude of the impact of LNP3 according to LNE, it is necessary to consider both of them together for decision-making.

Abstract
A system for analysis of histopathology data within a pharmaceutical R&D environment has been developed with the intention of enabling interdisciplinary collaboration. State-of-the-art AI tools have been deployed as easy-to-use self-service modules within an open-source whole slide image viewing platform, so that non-data scientist users (e.g., clinicians) can utilize and evaluate pre-trained algorithms and retrieve quantitative results. The outputs of analysis are automatically cataloged in the database to track data provenance and can be viewed interactively on the slide as annotations or heatmaps. Commonly used models for analysis of whole slide images including segmentation, extraction of hand-engineered features for segmented regions, and slide-level classification using multi-instance learning are included and new models can be added as needed. The source code that supports running inference with these models internally is backed up by a robust CI/CD pipeline to ensure model versioning, robust testing, and seamless deployment of the latest models. Examples of the use of this system in a pharmaceutical development workflow include glomeruli segmentation, enumeration of podocyte count from WT-1 immuno-histochemistry, measurement of beta-1 integrin target engagement from immunofluorescence, digital glomerular phenotyping from periodic acid-Schiff histology, PD-L1 score prediction using multi-instance learning, and the deployment of the open-source Segment Anything model to speed up annotation.

Abstract
BACKGROUND The AJCC 8th edition stratifies stage IV disseminated appendiceal cancer (dAC) patients based on grade and pathology. This study was designed to externally validate the staging system and to identify predictors of long-term survival. METHODS A 12-institution cohort of dAC patients treated with CRS ± HIPEC was retrospectively analyzed. Overall survival (OS) and recurrence-free survival (RFS) were analyzed by using Kaplan-Meier and log-rank tests. Univariate and multivariate cox-regression was performed to assess factors associated with OS and RFS. RESULTS Among 1009 patients, 708 had stage IVA and 301 had stage IVB disease. Median OS (120.4 mo vs. 47.2 mo) and RFS (79.3 mo vs. 19.8 mo) was significantly higher in stage IVA compared with IVB patients (p < 0.0001). RFS was greater among IVA-M1a (acellular mucin only) than IV M1b/G1 (well-differentiated cellular dissemination) patients (NR vs. 64 mo, p = 0.0004). Survival significantly differed between mucinous and nonmucinous tumors (OS 106.1 mo vs. 41.0 mo; RFS 46.7 mo vs. 21.2 mo, p < 0.05), and OS differed between well, moderate, and poorly differentiated (120.4 mo vs. 56.3 mo vs. 32.9 mo, p < 0.05). Both stage and grade were independent predictors of OS and RFS on multivariate analysis. Acellular mucin and mucinous histology were associated with better OS and RFS on univariate analysis only. CONCLUSIONS AJCC 8th edition performed well in predicting outcomes in this large cohort of dAC patients treated with CRS ± HIPEC. Separation of stage IVA patients based on the presence of acellular mucin improved prognostication, which may inform treatment and long-term, follow-up strategies.

Abstract
This case report follows a 23-year-old man who presented with a painful right scrotal mass which was found to be a paratesticular vascular solid mass on ultrasound, and after uncomplicated orchiectomy, was revealed to be a high-grade extraskeletal Ewing's sarcoma. Diagnosis leading up to the orchiectomy was primarily clinical with only ultrasound used in identification and characterization of the paratesticular mass. Paratesticular masses are more commonly benign, and ultrasound is the first modality, with computed tomography and magnetic resonance imaging providing more definitive findings. We discuss imaging findings and histopathology of this rare tumor with an uncommon presentation.

Abstract
BACKGROUND Malignant peritoneal mesothelioma (MPM) is a rare malignancy with a historically poor prognosis. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has emerged as an effective therapy for patients with peritoneal malignancies. A contemporary analysis of trends in management of and survival from MPM is warranted. METHODS Patients with MPM were identified from the National Cancer Database (2004-2018). Patients were categorized by treatment (CRS-HIPEC, CRS-chemotherapy, CRS only, chemotherapy only, no treatment), and joinpoint regression was employed to compute the annual percent change (APC) in treatment over time. Multivariable Cox proportional hazards models were used to analyze factors associated with survival. RESULTS Of 2683 patients with MPM, 19.1% underwent CRS-HIPEC, and 21.1% received no treatment. Joinpoint regression revealed a statistically significant increase in the proportion of patients undergoing CRS-HIPEC over time (APC 3.21, p = 0.01), and a concurrent decrease in the proportion of patients who underwent no treatment (APC - 2.21, p = 0.02). Median overall survival was 19.5 months. Factors independently associated with survival included CRS-HIPEC, CRS, histology, sex, age, race, Charlson Comorbidity Index, insurance, and hospital type. Although there was a strong association between year of diagnosis and survival on univariate analysis (2016-2018 HR 0.67, p < 0.001), this association was attenuated after adjustment for treatment. CONCLUSIONS CRS-HIPEC is increasingly employed as a treatment for MPM. In parallel, there has been a decrease in patients receiving no treatment with an increase in overall survival. These findings suggest that patients with MPM may be receiving more appropriate therapy; however, a substantial proportion of patients may remain undertreated.

Abstract
INTRODUCTION The impact of Medicaid expansion (ME) on hepatocellular carcinoma (HCC) remains controversial, and heterogeneous effects on care processes may relate to sociodemographic factors. We sought to evaluate the association between ME and receipt of surgery in early-stage HCC. METHODS Patients diagnosed with early-stage HCC between 40 and 64 years of age were identified from the National Cancer Database and divided into pre- (2004-2012) and post- (2015-2017) expansion cohorts. Logistic regression was used to identify predictors of surgical treatment. Difference-in-difference (DID) analysis assessed changes in surgical treatment between patients living in ME and non-ME states. RESULTS Among 19,745 patients, 12,220 (61.9%) were diagnosed before ME and 7525 (38.1%) after. Although overall utilization of surgery decreased after expansion (ME, pre-expansion: 62.2% versus post-expansion: 51.6%; non-ME, pre-expansion: 62.1% versus post-expansion: 50.8%, p < 0.001), this trend varied relative to insurance status. Notably, receipt of surgery increased among uninsured/Medicaid patients living in ME states after expansion (pre-expansion: 48.1%, post-expansion: 52.3%, p < 0.001). Moreover, treatment at academic or high-volume facilities increased the likelihood of undergoing surgery before expansion. After expansion, treatment at an academic facility and living in an ME state (OR 1.28, 95% CI 1.07-1.54, p < 0.01) were predictors of surgical treatment. DID analysis demonstrated increased utilization of surgery for uninsured/Medicaid patients living in ME states relative to non-ME states (uninsured/Medicaid: 6.4%, p < 0.05), although no differences were noted among patients with other insurance statuses (overall: 0.7%, private: -2.0%, other: 0.3%, all p > 0.05). CONCLUSIONS Implementation of ME heterogeneously impacted utilization of care in early-stage HCC. Notably, uninsured/Medicaid patients residing in ME states demonstrated increased utilization of surgical treatment after expansion.

Abstract
The polarized cross-section ratio σ_{LT^{'}}/σ_{0} from hard exclusive π^{-}Δ^{++} electroproduction off an unpolarized hydrogen target has been extracted based on beam-spin asymmetry measurements using a 10.2 GeV/10.6 GeV incident electron beam and the CLAS12 spectrometer at Jefferson Lab. The study, which provides the first observation of this channel in the deep-inelastic regime, focuses on very forward-pion kinematics in the valence regime, and photon virtualities ranging from 1.5 GeV^{2} up to 7 GeV^{2}. The reaction provides a novel access to the d-quark content of the nucleon and to p→Δ^{++} transition generalized parton distributions. A comparison to existing results for hard exclusive π^{+}n and π^{0}p electroproduction is provided, which shows a clear impact of the excitation mechanism, encoded in transition generalized parton distributions, on the asymmetry.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is associated with poor long-term outcomes, and limited evidence exists on optimal resection margin width. This study used artificial intelligence to investigate long-term outcomes and optimal margin width in hepatectomy for ICC. METHODS The study enrolled patients who underwent curative-intent resection for ICC between 1990 and 2020. The optimal survival tree (OST) was used to investigate overall (OS) and recurrence-free survival (RFS). An optimal policy tree (OPT) assigned treatment recommendations based on random forest (RF) counterfactual survival probabilities associated with each possible margin width between 0 and 20 mm. RESULTS Among 600 patients, the median resection margin was 4 mm (interquartile range [IQR], 2-10). Overall, 379 (63.2 %) patients experienced recurrence with a 5-year RFS of 28.3 % and a 5-year OS of 38.7 %. The OST identified five subgroups of patients with different OS rates based on tumor size, a carbohydrate antigen 19-9 [CA19-9] level higher than 200 U/mL, nodal status, margin width, and age (area under the curve [AUC]: training, 0.81; testing, 0.69). The patients with tumors smaller than 4.8 cm and a margin width of 2.5 mm or greater had a relative increase in 5-year OS of 37 % compared with the entire cohort. The OST for RFS estimated a 46 % improvement in the 5-year RFS for the patients younger than 60 years who had small (<4.8 cm) well- or moderately differentiated tumors without microvascular invasion. The OPT suggested five optimal margin widths to maximize the 5-year OS for the subgroups of patients based on age, tumor size, extent of hepatectomy, and CA19-9 levels. CONCLUSIONS Artificial intelligence OST identified subgroups within ICC relative to long-term outcomes. Although tumor biology dictated prognosis, the OPT suggested that different margin widths based on patient and disease characteristics may optimize ICC long-term survival.

Abstract
Chemotherapy remains the mainstay of treatment for patients with advanced liposarcoma (LPS), but response rates are only 25% and the overall survival at 5 years is dismal at 20-34%. Translation of other therapies have not been successful and there has been no significant improvement in prognosis for nearly 20 years. The aberrant activation of the phosphatidylinositol 3-kinase (PI3K)/AKT pathway has been implicated in the aggressive clinical behavior LPS and in resistance to chemotherapy, but the precise mechanism remains elusive and efforts to target AKT clinically have failed. Here we show that the AKT-mediated phosphorylation of the transcription elongation factor IWS1, promotes the maintenance of cancer stem cells in both cell and xenograft models of LPS. In addition, phosphorylation of IWS1 by AKT contributes to a "metastable" cell phenotype, characterized by mesenchymal/epithelial plasticity. The expression of phosphorylated IWS1 also promotes anchorage-dependent and independent growth, cell migration, invasion, and tumor metastasis. In patients with LPS, IWS1 expression is associated with reduced overall survival, increased frequency of recurrence, and shorter time to relapse after resection. These findings indicate that IWS1-mediated transcription elongation is an important regulator of human LPS pathobiology in an AKT-dependent manner and implicate IWS1 as an important molecular target to treat LPS.

Abstract
INTRODUCTION Neoadjuvant therapy (NT) is increasingly used before surgery for patients with gastrointestinal (GI) cancers. Treatment burden is a patient-centered measure defined as the work of being a patient and characterizes the impact of medical treatment on one's functioning and well-being. While treatment burden has previously been studied in chronic diseases and cancer survivorship, the treatment burden of undergoing NT is unknown. METHODS All patients enrolled in a prospective cohort study evaluating the real-time experience of NT for GI cancers completed either the Patient Experience with Treatment and Self-management (PETS) survey, a 46-item validated measure of treatment burden, or the mini-PETS questionnaire. PETS subsections were scored on a 5-point Likert scale and then standardized on a 100-point scale (a higher number means more treatment burden). Semistructured interviews were conducted among a convenience sample of patients (n = 5); qualitative data were coded and then analyzed using an integrated approach. RESULTS Among 126 participants, the mean age was 59 years old, 61% were male, and the mean number of comorbidities was 1.57. The most common cancers were colorectal (46%) and pancreatic (28%). The mean length of NT treatment was 3.7 months and 80.2% of patients underwent surgical resection following NT. The highest standardized treatment burden scores were observed in healthcare services (44 ± 15), social limitations (44 ± 26), exhaustion (41 ± 23), and medical expenses (40 ± 18) whereas the lowest scores were reported in medication use (19 ± 16) and interpersonal challenges (19 ± 17). Commonly experienced emotional symptoms were feeling worn out (43%) or frustrated (32%). No significant differences were observed in mean treatment burden subscores between patients who underwent surgery versus those who did not. Qualitative analysis of treatment burden during NT identified common themes of impact on normal life activities, challenges with healthcare access, impact on relationships, and significant physical and emotional symptoms. CONCLUSIONS NT is associated with a significant treatment burden, particularly in the domains of accessing healthcare services, social limitations, and exhaustion. Given the increasing use of NT for GI cancers, novel patient-centered approaches are needed to improve quality of life and ensure the completion of multimodality therapy.

Abstract
We report results of Λ hyperon production in semi-inclusive deep-inelastic scattering off deuterium, carbon, iron, and lead targets obtained with the CLAS detector and the Continuous Electron Beam Accelerator Facility 5.014 GeV electron beam. These results represent the first measurements of the Λ multiplicity ratio and transverse momentum broadening as a function of the energy fraction (z) in the current and target fragmentation regions. The multiplicity ratio exhibits a strong suppression at high z and an enhancement at low z. The measured transverse momentum broadening is an order of magnitude greater than that seen for light mesons. This indicates that the propagating entity interacts very strongly with the nuclear medium, which suggests that propagation of diquark configurations in the nuclear medium takes place at least part of the time, even at high z. The trends of these results are qualitatively described by the Giessen Boltzmann-Uehling-Uhlenbeck transport model, particularly for the multiplicity ratios. These observations will potentially open a new era of studies of the structure of the nucleon as well as of strange baryons.

Abstract
STUDY DESIGN Double-blinded, prospective laboratory animal study. OBJECTIVE To examine if intraoperative spinal cord stimulation (SCS) inhibits the development of spine surgery-induced hypersensitivity. SUMMARY OF BACKGROUND DATA Managing postoperative pain after spine surgery is challenging, and as many as 40% of patients may develop failed back surgery syndrome (FBSS). While SCS has been shown to effectively reduce chronic pain symptoms, it is unknown if intraoperative SCS can mitigate the development of central sensitization that potentially leads to FBSS after spine surgery. METHODS Mice were randomly stratified into three experimental groups:1) sham surgery; 2) laminectomy alone; 3) laminectomy plus SCS. Secondary mechanical hypersensitivity was measured in hind paws using von Frey assay one day before and at predetermined times after surgery. In addition, we also performed a conflict avoidance test to capture the affective-motivational domain of pain at selected time points post-laminectomy. RESULTS Mice that underwent unilateral T13 laminectomy developed mechanical hypersensitivity in both hind paws. Intraoperative SCS applied to the exposed side of the dorsal spinal cord significantly inhibited the development of hind paw mechanical hypersensitivity on the SCS-applied side. Sham surgery did not produce any obvious secondary mechanical hypersensitivity in the hind paws. CONCLUSION These results demonstrate that spine surgery for unilateral laminectomy induces central sensitization that results in postoperative pain hypersensitivity. Intraoperative SCS after laminectomy may be able to mitigate the development of this hypersensitivity in appropriately selected cases.

Abstract
BACKGROUND Area-level social determinants of health (SDoH) impact access to cancer care and prevention. Little is known about the factors that underlie the impact of residential privilege on county-level cancer screening uptake. METHODS Population-based cross-sectional study examining county-level data was obtained from the Centers for Disease Control and Prevention's PLACES database, American Community Survey and the County Health Rankings and Roadmap database. The Index of Concentration of Extremes (ICE), a validated measure of racial and economic privilege, was examined relative to county-level rates of US Preventive Services Task Force (USPSTF) guideline-concordant screening for breast, cervical, and colorectal cancers. Generalized structural equation modeling was used to determine the indirect and direct effects of ICE on cancer screening uptake. RESULTS Across 3142 counties, county-level cancer screening rates demonstrated geographical variation ranging from 54.0% to 81.8% for breast cancer screening, from 39.8% to 74.4% for colorectal cancer screening, and from 69.9% to 89.7% for cervical cancer screening. Of note, cancer screening rates for breast, colorectal, and cervical cancer all increased from lower (ICE-Q1) to higher (ICE-Q4) privileged areas (breast: Q1 = 71.0% vs. Q4 = 72.2%; colorectal: Q1 = 59.4% vs. Q4 = 65.0%; cervical: Q1 = 83.3% vs. Q4 = 85.2%; all p < 0.001). Mediation analysis revealed that the observed disparities between ICE and cancer screening uptake were explained by mediators such as poverty status, lack of health insurance or employment, urban-rural location and access to primary care physicians that accounted for 64% (95% confidence interval [CI]: 61%-67%), 85% (95% CI: 80%-89%), and 74% (95% CI: 71%-77%) of the effect on breast, colorectal, and cervical cancer screening, respectively. CONCLUSIONS In this cross-sectional study, the association between racial and economic privilege on USPSTF-recommended cancer screening was complex and influenced by an interplay of sociodemographic, geographical, and structural factors. Understanding the underlying area-level SDoH that mediate disparities in cancer prevention strategies can help focus interventions to improve equity in cancer prevention.

Abstract
Background The colonic mucus bilayer is an integral innate host defense mechanism that provides a physical barrier separating the lumen and its contents from the underlying epithelium. This essential barrier is produced by specialized secretory goblet cells of which Muc2 mucin is its primary product. IgG-Fc-binding protein (Fcgbp) is the second most abundant protein produced by goblet cells, which has a suggested function of crosslinking with Muc2 to stabilize the structural integrity of mucus. FCGBP is observed to decrease preceding the onset of inflammation in ulcerative colitis patients, leading to spatially distinct structural mucus weakening to contribute to the pathogenesis of the disease. Purpose Fcgbp is altered regionally in the gut and plays a role in the pathogenesis of dextran sulfate sodium (DSS)-induced colitis. The specific aims are: To characterize the spatial expression of Muc2 and Fcgbp basally in goblet cells To quantify alterations in Muc2 and Fcgbp in response to DSS-induced colitis and at restitution of disease Method mRNA and protein expression in Muc2+/+ and Muc2-/- C57BL/6 littermates were analyzed by RT-qPCR and Western blotting, respectively. Mucin granules were isolated from colonic goblet cells and the proteome quantified by liquid chromatography and tandem mass spectrometry (LC-MS/MS). Colitis was induced in Muc2+/+ mice with 3.5% (w/v) DSS in tap water for five days, whereas Muc2-/- littermates were given 1.5% (w/v) DSS in tap water for three days, ad libitum. Mice were given regular tap water for the remainder of the experiment to allow restitution of inflammation. Disease activity index (DAI) was scored based on weight loss. Mice were sacrificed at various time points up to 10 days, and colons excised and sectioned for histopathology analysis. Result(s) LC-MS/MS of mucin granules run under reducing and non-reducing conditions confirmed that Muc2 and Fcgbp were the most abundant proteins in mucin granules and were non-covalently bound to each other. mRNA and protein expression of Muc2 and Fcgbp were highly expressed in the mid colon, and regulation of Fcgbp was unaffected in Muc2-/- littermates. In response to DSS-induced colitis in Muc2+/+ mice, Muc2 transcription rapidly increased in all regions of the colon with highest expression in the mid colon. In contrast, Fcgbp transcription increased in the mid and distal colons and peaked during highest disease activity. Interestingly, Fcgbp protein expression was abrogated in the mid colon even at restitution. In Muc2-/- mice, Fcgbp transcription decreased during disease onset but returned to normal levels following removal of DSS. Image ![]()
Conclusion(s) This study demonstrates that in response to DSS, Fcgbp expression was spatially degraded at the onset of disease and remained low at restitution. The disappearance of Fcgbp in the mid colon of Muc2+/+ littermates, despite Muc2 restoration, suggests that the mucus barrier remains structurally altered and functionally impaired at restitution.

Abstract
BACKGROUND The addition of radiation therapy to surgery for retroperitoneal sarcoma remains controversial. Improved patient selection may help identify optimal candidates for multimodality treatment. The aim of this analysis was to define prognostic factors among patients who receive radiation therapy and surgery to aid in patient selection for multimodal therapy. METHODS Patients who received radiation therapy and underwent curative-intent resection for retroperitoneal sarcoma between 2004 and 2016 were identified from a national cohort in the United States (National Cancer Database). A machine-based classification and regression tree model was used to generate similar groups of patients relative to overall survival based on preoperative factors. RESULTS A total of 1,443 patients received radiation therapy in addition to surgery. Median age was 61 years old and 55.0% were female. Most patients (66%) received care at an academic or integrated network cancer program. With a median follow-up of 84 months, receipt of radiation therapy was not associated with improved overall survival (P = .81). Classification and regression tree analysis revealed a significant association between overall survival and American Joint Committee on Cancer stage group, age, tumor histology, and Charlson comorbidity score. Application of these parameters via machine learning stratified patients into 5 cohorts with distinct survival outcomes. In the most favorable cohort (Cohort 1: American Joint Committee on Cancer stage group ≤II, age ≤61, histology including fibrosarcoma, well differentiated liposarcoma, myxoid liposarcoma, and leiomyosarcoma), the 5-year overall survival was 81.7% and median overall survival was not reached; in the least favorable cohort (Cohort 6: American Joint Committee on Cancer stage group >II, age >68) where the 5-year survival was 41.3% and median overall survival was 45.2 months (P < .001 versus Cohort 1). CONCLUSION In the absence of a defined survival benefit, patients with advanced American Joint Committee on Cancer stage group, older age, and medical comorbidities have relatively unfavorable overall survival after combined modality therapy and therefore stand the least to gain from the addition of radiation therapy to surgery. In contrast, younger patients with good performance status and retroperitoneal sarcoma histologies with a higher propensity for local recurrence may have the greatest opportunity to benefit from radiation therapy.

Abstract
INTRODUCTION The long-term prognosis of patients who undergo cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal surface malignancies (PSM) varies considerably on the basis of histological and operative factors. While overall survival (OS) estimates are used to inform adjuvant therapy and surveillance strategies, conditional survival may provide more clinically relevant estimates of prognosis by accounting for disease-free time elapsed. PATIENTS AND METHODS All patients from 12 academic institutions who underwent CRS ± HIPEC for PSM from 2000 to 2017 were retrospectively analyzed. OS and disease-free survival (DFS) rates were calculated using the Kaplan-Meier method while conditional overall (COS) and conditional disease-free survival (CDFS) rates were calculated at 1, 2, or 3 years from surgery for different tumor histologies. RESULTS Overall, 1610 patients underwent CRS ± HIPEC. Among patients with benign appendiceal mucinous tumors (N = 460), 5-year OS and COS at 3 years were 92.1% and 96.3% (Δ4.2%), respectively. For patients with well-differentiated appendiceal cancers (N = 400), 5-year OS and COS at 3 years were 76.3% and 88.3% (Δ12.0%), respectively. For patients with high-grade appendiceal cancers (N = 258), 5-year OS and COS at 3 years were 43.8% and 75.4% (Δ31.6%), respectively. For patients with colorectal cancers (N = 362), 5-year OS and COS at 3 years were 31.8% and 67.3% (Δ35.5%), respectively. For patients with peritoneal mesothelioma (N = 130), 5-year OS and COS at 3 years were 67.6% and 89.7% (Δ22.1%), respectively. Similar trends were observed for DFS/CDFS. CONCLUSION The conditional survival of patients undergoing CRS ± HIPEC for PSM is associated with tumor histology. COS and CDFS provide a more accurate, dynamic estimate of survival than OS and DFS, especially for patients with more aggressive histologies.

Abstract
We report the first measurements of deep inelastic scattering spin-dependent azimuthal asymmetries in back-to-back dihadron electroproduction in the deep inelastic scattering process. In this reaction, two hadrons are produced in opposite hemispheres along the z axis in the virtual photon-target nucleon center-of-mass frame, with the first hadron produced in the current-fragmentation region and the second in the target-fragmentation region. The data were taken with longitudinally polarized electron beams of 10.2 and 10.6 GeV incident on an unpolarized liquid-hydrogen target using the CLAS12 spectrometer at Jefferson Lab. Observed nonzero sinΔϕ modulations in ep→e^{'}pπ^{+}X events, where Δϕ is the difference of the azimuthal angles of the proton and pion in the virtual photon and target nucleon center-of-mass frame, indicate that correlations between the spin and transverse momenta of hadrons produced in the target- and current-fragmentation regions may be significant. The measured beam-spin asymmetries provide a first access in dihadron production to a previously unexplored leading-twist spin- and transverse-momentum-dependent fracture function. The fracture functions describe the hadronization of the target remnant after the hard scattering of a virtual photon off a quark in the target particle and provide a new avenue for studying nucleonic structure and hadronization.

Abstract
Astrophysical reactions involving radioactive isotopes (RI) often play an important role in high-temperature stellar environments. The experimental studies on the reaction rates for those are still limited mainly due to the technical difficulties in producing high-quality RI beams. A direct measurement of those reactions would be still challenging in many cases, however, we can make a reliable evaluation of the reaction rates by an indirect method or by studying the resonance prorerties. Here we ntroduce recent examples of experimental studies on such RI-involving astrophysical reactions, performed at Center for Nuclear Study, the University of Tokyo, using the low-energy RI beam separator CRIB. One is for the neutron-induced destruction reactions of 7Be in the Big-Bang nucleosynthesis, and the other is the study on the 22Mg(α, p) reaction relevant in X-ray bursts, which was performed with the resonant scattering method from the inverse reaction channel.

Abstract
Background: Malignant peritoneal mesothelioma (MPM) is a rare disease with a historically poor prognosis. Given the emergence of effective therapies, a contemporary analysis of MPM incidence and survival is warranted. Methods: The SEER-18 registry dataset was analyzed (2000−2018). Age-adjusted annual incidence was stratified by sex and histology. Joinpoint regression was used to estimate annual percent change (APC) in incidence. Multivariable cox proportional hazards models were used to investigate survival trends. Results: Of 1689 MPM cases, most were male (55.4%), >50 years (80.0%), and white (75.2%). Age-adjusted incidence of MPM remained stable over time, with an average annual incidence of 1.02 cases/million. Epithelioid histology increased by 240% (APC 2.6; 95% CI: 0.7, 4.5), while incidence of undefined histology decreased significantly (APC −2.1; 95% CI: −3.1, −1.1). Cases treated with cancer-directed surgery increased from 27% to 43%. Overall median age-standardized survival was 11.6 months. Median age-standardized survival was 16.6 months for epithelioid histology but 2.0 months for sarcomatoid histology. Diagnosis in recent years (2015−2018 HR 0.51; 95% CI: 0.38, 0.67) and receipt of cancer-directed surgery (HR 0.84; 95% CI: 0.72, 0.98) were associated with improved survival. Conclusions: Although the overall incidence of MPM remained stable, recognition of epithelioid histology increased. Concurrent with an increase in cancer-directed surgery, MPM survival has improved.

Abstract
Prior studies have demonstrated the beneficial effects of real-time data feedback (RTF) on athletic performance and motivation. Despite this evidence, the lack of practical means to implement RTF has hindered its widespread adoption. Recently, a smart-resisted sled push was developed to improve athletic power by utilizing electromagnetic motors as a resistance mechanism, coupled with an RTF display. Thirty healthy college-aged male football players were recruited in this randomized, crossover designed study to examine the efficacy of the RTF to improve power output. Participants were randomized into either group 1 (receiving RTF first then no RTF) or group 2 (receiving no RTF first then RTF) during six, 10-meter sled pushes with 3 min rest intervals. The first three pushes were set to an easier level (L1) and the last three were set to a resistance level twice that of the first three runs (L2). A one-month washout period was enforced. For trials 1-3 (L1) (p = 0.026, t = -2.34, ES = -0.428) and 4-6 (L2) (p = 0.035, t = -2.22, ES = -0.405), peak power output (the average peak power output over the course of trials 1-3 and 4-6) was greater in both groups when receiving RTF compared to no-RTF. These findings demonstrate the effectiveness of RTF in augmenting power output during performance training.

Abstract
This case report follows a 47-year-old man who had multiple grafts undergoing FDG PET/CT (positron emission tomography/computed tomography) scan to evaluate for graft infection. Initial CT showed enhancing soft tissue and fluid collection around the graft, and the subsequent FDG PET/CT showed findings concerning for graft infection. This case exemplifies that FDG PET/CT is a synergistic tool in diagnosing aortic graft infections, a rare and often fatal complication of aortic grafts.

Abstract
Background Tuberculosis (TB) remains a global public health threat. WHO determined Kazakhstan as one of 18 high-priority countries for TB elimination in Europe, with reported TB incidence >20 cases per 100,000 population. There is a lack of comprehensive reseach of TB epidemiology in the country. This study aims to estimate the prevalence, incidence, mortality rates and survival hazard ratios of TB in Kazakhstan, using large-scale administrative health data records in 2014-2019. Methods This is a population-wide retrospective study assessing 150 thousand TB (ICD10: A15-A19) patients’ incidence, prevalence and mortality. Demographic factors, diagnoses and comorbidities were analyzed. Univariate, bivariate and multivariate statistical analyses were performed. Cox regression and Kaplan-Meier survival analysis have been done. Results Out of 150 thousand all TB patients, 61 percent were male and 94 percent had respiratory TB. During 2014-2019, the TB incidence, prevalence and mortality per 100K population declined (227-15.2), doubled (325.3-746.6) and increased (8.4-15.2), respectively. Age-specific TB incidence was lowest for 0-10 y.o., highest for 20 y.o. Being an old person, male, urban resident, retired, with HIV and diabetes was significantly associated with lower survival compared to a young, female, rural resident, employed, with no comorbidities. Conclusions This was the largest TB study in Kazakhstan, presenting the country’s TB by demographic groups, incidence, prevalence, mortality trends, and risk factors against survival. Key messages • During 2014-2019, the TB incidence, prevalence and mortality per 100K population declined (227-15.2), doubled (325.3-746.6) and increased (8.4-15.2), respectively. • Being an old person, male, urban resident, retired, with HIV and diabetes was significantly associated with lower survival compared to a young, female, rural resident, employed, with no comorbidities.

Abstract
Sustainable investing recognizes companies’ role in solving some of the major sustainability challenges globally and that companies driving impactful sustainability agendas can be best positioned to grow, and one way to do this is through inclusion into a sustainability stock-market index. Current research has investigated the financial benefits of being included into sustainable indices and has found contrasting results. To expand on existing work, we report an analysis that aims at better understanding whether there is any negative economic impact related to participation in the sustainability index DJSI. To do this, we gained data on three financial indicators (market cap, net sales, and EBITDA) on five different non-related industries (Airlines, Aluminum, Apparel, Pharmaceuticals, and Forest Products). Ten companies in each industry were selected based on market-cap, with 5 being in-index and 5 being out. Although most indices’ rationale is to identify companies that are best-in-class performers in sustainability and economically, we report an unexpected conclusion of no obvious financial consequences from being part of sustainability index. Only one industry—forest products—had positive impacts of index-inclusion, and the other industries’ impacts were non-consequential. This indicates that sustainability indices may promote sustainable development with no financial impact.
