Item A Clinical Severity Index for Eosinophilic Esophagitis: Development, Consensus, and Future Directions(Elsevier, 2022) Dellon, Evan S.; Khoury, Paneez; Muir, Amanda B.; Liacouras, Chris A.; Safroneeva, Ekaterina; Atkins, Dan; Collins, Margaret H.; Gonsalves, Nirmala; Falk, Gary W.; Spergel, Jonathan M.; Hirano, Ikuo; Chehade, Mirna; Schoepfer, Alain M.; Menard-Katcher, Calies; Katzka, David A.; Bonis, Peter A.; Bredenoord, Albert J.; Geng, Bob; Jensen, Elizabeth T.; Pesek, Robert D.; Feuerstadt, Paul; Gupta, Sandeep K.; Lucendo, Alfredo J.; Genta, Robert M.; Hiremath, Girish; McGowan, Emily C.; Moawad, Fouad J.; Peterson, Kathryn A.; Rothenberg, Marc E.; Straumann, Alex; Furuta, Glenn T.; Aceves, Seema S.; Pediatrics, School of MedicineBackground & aims: Disease activity and severity of eosinophilic esophagitis (EoE) dictate therapeutic options and management, but the decision-making process for determining severity varies among practitioners. To reduce variability in practice patterns and help clinicians monitor the clinical course of the disease in an office setting, we aimed to create an international consensus severity scoring index for EoE. Methods: A multidisciplinary international group of adult and pediatric EoE researchers and clinicians, as well as non-EoE allergy immunology and gastroenterology experts, formed 3 teams to review the existing literature on histology, endoscopy, and symptoms of EoE in the context of progression and severity. A steering committee convened a 1-day virtual meeting to reach consensus on each team's opinion on salient features of severity across key clinicopathologic domains and distill features that would allow providers to categorize disease severity. Results: Symptom features and complications and inflammatory and fibrostenotic features on both endoscopic and histologic examination were collated into a simplified scoring system-the Index of Severity for Eosinophilic Esophagitis (I-SEE)-that can be completed at routine clinic visits to assess disease severity using a point scale of 0-6 for mild, 7-14 for moderate, and ≥15 for severe EoE. Conclusions: A multidisciplinary team of experts iteratively created a clinically usable EoE severity scoring system denominated "I-SEE" to guide practitioners in EoE management by standardizing disease components reflecting disease severity beyond eosinophil counts. I-SEE should be validated and refined using data from future clinical trials and routine clinical practice to increase its utilization and functionality.Item A Sodium Oxychlorosene-Based Infection Prevention Protocol Safely Decreases Postoperative Wound Infections in Adult Spinal Deformity Surgery(Springer Nature, 2024-03-13) Alentado, Vincent J.; Kazi, Fezaan A.; Potts, Caroline A.; Zaazoue, Mohamed A.; Pott, Eric A.; Khairi, Saad A.; Neurological Surgery, School of MedicineIntroduction: This study sought to determine the efficacy of a complex multi-institutional sodium oxychlorosene-based infection protocol for decreasing the rate of surgical site infection after instrumented spinal surgery for adult spinal deformity (ASD). Infection prevention protocols have not been previously studied in ASD patients. Methods: A retrospective analysis was performed of patients who underwent posterior instrumented spinal fusion of the thoracic or lumbar spine for deformity correction between January 1, 2011, and May 31, 2019. The efficacy of a multi-modal infection prevention protocol was examined. The infection prevention bundle consisted of methicillin-resistant Staphylococcus aureus testing, chlorhexidine gluconate bathing preoperatively, sodium oxychlorosene rinse, vancomycin powder placement, and surgical drain placement at the time of surgery. Results: About 254 patients fit the inclusion criteria. Among these patients, nine (3.5%) experienced post-surgical deep-wound infection. Demographics and surgical characteristics amongst infected and non-infected cohorts were similar, although diabetes trended towards being more prevalent in patients who developed a postoperative wound infection (p=0.07). Among 222 patients (87.4%) who achieved a minimum of two years of follow-ups, 184 patients (82.9%) experienced successful fusion, comparing favorably with pseudarthrosis rates in the ASD literature. Rates of pseudarthrosis and proximal junction kyphosis were similar amongst infected and non-infected patients. Conclusion: An intraoperative comprehensive sodium oxychlorosene-based infection prevention protocol helped to provide a low rate of infection after major deformity correction without negatively impacting other postoperative procedure-related metrics.Item Assessment and management of hypertension in patients on dialysis(American Society of Nephrology, 2014-08) Agarwal, Rajiv; Flynn, Joseph; Pogue, Velvie; Rahman, Mahboob; Reisin, Efrain; Weir, Matthew R.; Department of Medicine, IU School of MedicineHypertension is common, difficult to diagnose, and poorly controlled among patients with ESRD. However, controversy surrounds the diagnosis and treatment of hypertension. Here, we describe the diagnosis, epidemiology, and management of hypertension in dialysis patients, and examine the data sparking debate over appropriate methods for diagnosing and treating hypertension. Furthermore, we consider the issues uniquely related to hypertension in pediatric dialysis patients. Future clinical trials designed to clarify the controversial results discussed here should lead to the implementation of diagnostic and therapeutic techniques that improve long-term cardiovascular outcomes in patients with ESRD.Item Assessment of morbidity and mortality after liver transplantation for primary sclerosing cholangitis(AME, 2024) Ekser, Burcin; Mihaylov, Plamen; Mangus, Richard S.; Surgery, School of MedicineItem Clip Closure Prevents Bleeding After Endoscopic Resection of Large Colon Polyps in a Randomized Trial(Elsevier, 2019-10) Pohl, Heiko; Grimm, Ian S.; Moyer, Matthew T.; Hasan, Muhammad K.; Pleskow, Douglas; Elmunzer, B. Joseph; Khashab, Mouen A.; Sanaei, Omid; Al-Kawas, Firas H.; Gordon, Stuart R.; Mathew, Abraham; Levenick, John M.; Aslanian, Harry R.; Antaki, Fadi; von Renteln, Daniel; Crockett, Seth D.; Rastogi, Amit; Gill, Jeffrey A.; Law, Ryan J.; Elias, Pooja A.; Pellise, Maria; Wallace, Michael B.; Mackenzie, Todd A.; Rex, Douglas K.; Medicine, School of MedicineBackground & aims: Bleeding is the most common severe complication after endoscopic mucosal resection of large colon polyps and is associated with significant morbidity and cost. We examined whether prophylactic closure of the mucosal defect with hemoclips after polyp resection reduces the risk of bleeding. Methods: We performed a multicenter, randomized trial of patients with a large nonpedunculated colon polyp (≥20 mm) at 18 medical centers in North America and Spain from April 2013 through October 2017. Patients were randomly assigned to groups that underwent endoscopic closure with a clip (clip group) or no closure (control group) and followed. The primary outcome, postprocedure bleeding, was defined as a severe bleeding event that required hospitalization, a blood transfusion, colonoscopy, surgery, or another invasive intervention within 30 days after completion of the colonoscopy. Subgroup analyses included postprocedure bleeding with polyp location, polyp size, or use of periprocedural antithrombotic medications. We also examined the risk of any serious adverse event. Results: A total of 919 patients were randomly assigned to groups and completed follow-up. Postprocedure bleeding occurred in 3.5% of patients in the clip group and 7.1% in the control group (absolute risk difference [ARD] 3.6%; 95% confidence interval [CI] 0.7%-6.5%). Among 615 patients (66.9%) with a proximal large polyp, the risk of bleeding in the clip group was 3.3% and in the control group was 9.6% (ARD 6.3%; 95% CI 2.5%-10.1%); among patients with a distal large polyp, the risks were 4.0% in the clip group and 1.4% in the control group (ARD -2.6%; 95% CI -6.3% to -1.1%). The effect of clip closure was independent of antithrombotic medications or polyp size. Serious adverse events occurred in 4.8% of patients in the clip group and 9.5% of patients in the control group (ARD 4.6%; 95% CI 1.3%-8.0%). Conclusions: In a randomized trial, we found that endoscopic clip closure of the mucosal defect following resection of large colon polyps reduces risk of postprocedure bleeding. The protective effect appeared to be restricted to large polyps located in the proximal colon.Item Collaboration Is Key for Successful Treatment of Youth-Onset Type 2 Diabetes(Elsevier, 2017-04) Folsom, Lisal J.; Hannon, Tamara S.; Pediatrics, School of MedicineType 2 diabetes (T2D) is increasing in U.S. adolescents, particularly those of ethnic and racial minority groups. Risk factors for youth-onset T2D include obesity, family history of T2D, poor diet, lack of exercise, and poverty. The onset of diabetes-related complications is accelerated in adolescents with T2D compared to adults, and knowledge regarding the optimal way to prevent and slow complications is lacking. Existing treatment options are limited, and research into novel pharmacologic treatments is hindered by lack of sufficient patient population for clinical trials. Health care providers and investigators should collaborate both with each other, and with patients and their communities to build networks that will allow comprehensive evaluation of this disease in order to offer optimal, comprehensive care for these adolescents.Item Comparative Responsiveness of Pain Measures in Cancer Patients(Elsevier, 2012-08) Kroenke, Kurt; Theobald, Dale; Wu, Jingwei; Tu, Wanzhu; Krebs, Erin E.; Department of Medicine, IU School of MedicineBrief measures to assess and monitor pain in cancer patients are available, but few head-to-head psychometric comparisons of different measures have been reported. Baseline and 3-month data were analyzed from 274 patients enrolled in the Indiana Cancer Pain and Depression (INCPAD) trial. Participants completed the Brief Pain Inventory (BPI), the PEG (a 3-item abbreviated version of the BPI), the short form (SF)-36 pain scale, and a pain global rating of change measure. The global rating was used as the criterion for standardized response mean and receiver operating characteristic curve analyses. To assess responsiveness to the trial intervention, we evaluated standardized effect size statistics stratified by trial arm. All measures were responsive to global improvement, discriminated between participants with and without improvement, and detected a significant intervention treatment effect. Short and longer measures were similarly responsive. Also, composite measures that combined pain severity and interference into a single score (BPI total, PEG, SF-36 pain) performed comparably to separate measures of each domain (BPI severity and BPI interference).Item Comparison of isoflurane and α-chloralose in an anesthetized swine model of acute pulmonary embolism producing right ventricular dysfunction(American Association for Laboratory Animal Science, 2015-02) Beam, Daren M.; Neto-Neves, Evandro M.; Stubblefield, William B.; Alves, Nathan J.; Tune, Johnathan D.; Kline, Jeffrey A.; Department of Emergency Medicine, IU School of MedicinePulmonary embolism (PE) is a leading cause of sudden cardiac death, and a model is needed for testing potential treatments. In developing a model, we compared the hemodynamic effects of isoflurane and α-chloralose in an acute swine model of PE because the choice of anesthesia will likely affect the cardiovascular responses of an animal to PE. At baseline, swine that received α-chloralose (n = 6) had a lower heart rate and cardiac output and higher SpO2, end-tidal CO2, and mean arterial pressure than did those given isoflurane (n = 9). After PE induction, swine given α-chloralose compared with isoflurane exhibited a lower heart rate (63 ± 10 compared with 116 ± 15 bpm) and peripheral arterial pressure (52 ± 12 compared with 61 ± 12 mm Hg); higher SpO2 (98% ± 3% compared with 95% ± 1%), end-tidal CO2 (35 ± 4 compared with 32 ± 5), and systolic blood pressure (121 ± 8 compared with 104 ± 20 mm Hg); and equivalent right ventricular:left ventricular ratios (1.32 ± 0.50 compared with 1.23 ± 0.19) and troponin I mean values (0.09 ± 0.07 ng/mL compared with 0.09 ± 0.06 ng/mL). Isoflurane was associated with widely variable fibrinogen and activated partial thromboplastin time. Intraexperiment mortality was 0 of 6 animals for α-chloralose and 2 of 9 swine for isoflurane. All swine anesthetized with α-chloralose survived with sustained pulmonary hypertension, RV-dilation-associated cardiac injury without the confounding vasodilatory or coagulatory effects of isoflurane. These data demonstrate the physiologic advantages of α-chloralose over isoflurane for anesthesia in a swine model of severe submassive PE.Item Complications in body contouring stratified according to weight loss method(SAGE Journals, 2016) Chetta, Matthew D.; Aliu, Oluseyi; Tran, Bao Anh Patrick; Abdulghani, Mariam; Kidwell, Kelly M.; Momoh, Adeyiza O.; Surgery, School of MedicineBACKGROUND: Body contouring procedures following massive weight loss have become increasingly common and, unfortunately, continue to be associated with a high complication rate. OBJECTIVE: To evaluate how weight loss method affects complications following abdominally based body contouring procedures. METHODS: Patients undergoing abdominally based contouring procedures were retrospectively evaluated over an 11-year period and stratified into two groups based on method of weight loss: diet and exercise; or bariatric surgery. Complications, including seroma, wound dehiscence, skin necrosis, infection, hematoma and venous thromboembolism, were included if they required intervention. An adjusted logistic model was used to examine the effect of weight loss method on aggregate complication rates. RESULTS: A total of 307 patients were included: 77 (25%) lost weight through diet and exercise; and 230 (75%) through bariatric surgery. Results from the logistic model showed no difference in complication rates between weight loss methods (OR 1.01 [95% CI 0.51 to 2.02]). However, there was a strong correlation between body mass index at the time of surgery and complication rates (OR 1.05 [95% CI 1.02 to 1.08]; P<0.01). CONCLUSIONS: The findings reveal no difference in complication rates following abdominal body contouring procedures attributable to method of weight loss. Rather, there was a proportional rise in complication rates in patients with a higher body mass index at the time of surgery. Surgeons and patients should be aware of this trend, and it should be part of any discussion of abdominal body contouring procedures and informing patients of their risk profile.Item Detection of Hepatocellular Carcinoma in Hepatitis C Patients: Biomarker Discovery by LC-MS(Elsevier, 2014-09-01) Bowers, Jeremiah; Hughes, Emma; Skill, Nicholas; Maluccio, Mary; Raftery, Daniel; Department of Surgery, IU School of MedicineHepatocellular carcinoma (HCC) accounts for most cases of liver cancer worldwide; contraction of hepatitis C (HCV) is considered a major risk factor for liver cancer even when individuals have not developed formal cirrhosis. Global, untargeted metabolic profiling methods were applied to serum samples from patients with either HCV alone or HCC (with underlying HCV). The main objective of the study was to identify metabolite based biomarkers associated with cancer risk, with the long term goal of ultimately improving early detection and prognosis. Serum global metabolite profiles from patients with HCC (n=37) and HCV (n=21) were obtained using high performance liquid chromatography-mass spectrometry (HPLC-MS) methods. The selection of statistically significant metabolites for partial least-squares discriminant analysis (PLS-DA) model creation based on biological and statistical significance was contrasted to that of a traditional approach utilizing p-values alone. A PLS-DA model created using the former approach resulted in a model with 92% sensitivity, 95% specificity, and an AUROC of 0.93. A series of PLS-DA models iteratively utilizing three to seven metabolites that were altered significantly (p<0.05) and sufficiently (FC≤0.7 or FC≥1.3) showed the best performance using p-values alone, the PLS-DA model was capable of generating 73% sensitivity, 95% specificity, and an AUROC of 0.92. Metabolic profiles derived from LC-MS readily distinguish patients with HCC and HCV from those with HCV only. Differences in the metabolic profiles between highrisk individuals and HCC indicate the possibility of identifying the early development of liver cancer in at risk patients. The use of biological significance as a selection process prior to PLSDA modeling may offer improved probabilities for translation of newly discovered biomarkers to clinical application.
