Abstract	Esophageal neuroendocrine carcinoma is very rare and highly aggressive. An 85-year-old man with a history of esophageal squamous cell carcinoma in remission presented 4 years after definitive chemoradiation with new-onset dysphagia. Endoscopy with biopsy revealed high-grade malignancy consistent with neuroendocrine carcinoma. Treatment options were limited to chemotherapy because of his metastatic disease, and he unfortunately died 14 months after diagnosis. The occurrence of esophageal neuroendocrine carcinoma in a site of prior squamous cell carcinoma is very uncommon, and this likely represents a case of radiation-induced malignancy. Therefore, when undergoing radiotherapy, patients and providers should discuss the possibility of this life-threatening complication.

Abstract	Pancreatic cancer can be aggressive and commonly metastasizes to various organs. Most commonly, pancreatic cancer metastasizes to the lung, liver, bones, and peritoneum, but very rarely does it spread to the abdominal wall or skeletal muscle. In this case, we discuss a patient who initially presented with weight loss and jaundice from a pancreatic head adenocarcinoma that later metastasized to the rectus abdominis muscle. A 63-year-old female presented with jaundice and weight loss. CT imaging revealed a 2.8 cm pancreatic head mass with pancreatic and biliary ductal dilation. Carbohydrate antigen 19-9 (CA 19-9) level was also found to be elevated to 1810 U/mL. An endoscopic ultrasound-guided biopsy was later performed and confirmed pancreatic adenocarcinoma. The patient underwent a Whipple pancreatoduodenectomy following initial treatment with neoadjuvant FOLFIRINOX chemotherapy. Following the Whipple procedure, she received adjuvant chemotherapy and subsequent imaging revealed no recurrence and decreased CA 19-9 level to 46 U/mL. Eight months afterward, the patient presented once again with lower abdominal pain. Repeat CA 19-9 level was found to have increased to 1503 U/mL. Repeat positron emission tomography scan imaging was performed and showed a 4.7 cm left rectus abdominis muscle mass. The mass was later biopsied, and pathology revealed recurrent, metastatic pancreatic adenocarcinoma. The patient was restarted on chemotherapy with paclitaxel and gemcitabine leading to a reduction in tumor size and CA 19-9 levels of 135 U/mL. However, surgical resection was later pursued due to increased tumor size only four months later. At this time, limited literature is available reporting the occurrence of pancreatic cancer metastasizing to the abdominal wall. Upon literature review, only five cases have been reported to date, and only two of the cases involved the skeletal muscle. Our rare case is the first-time documentation of rectus abdominis metastasis from pancreatic adenocarcinoma arising from the pancreatic head.

Abstract	Introduction There is scarce data about the association of metabolic syndrome (MetS) or its components with the development of colonic diverticulosis (CD) in the elderly. We aim to determine the association of MetS and its components with CD in the elderly aged ≥75 years. Methods We conducted a retrospective chart review at St. Luke's University Health Network to identify patients who underwent a colonoscopy between 2011 and 2020. We collected data on patient demographics, comorbidities, and colonoscopy findings. Statistical analyses were conducted to compute means and frequencies of patient characteristics and rates of CD, as well as to test for associations between potential risk factors and the presence of CD. Results A total of 1239 patients were included with a median age of 80 years, 57.6% females, 89.5% Caucasians, 72.9% with CD, and 66.7% having a left-sided disease. On bivariate analysis, the older age group (p=0.02), Caucasian ethnicity (p=0.01), and hypertension (p=0.04) were found to be significant risk factors for developing CD. Multivariate regression analysis showed older age group and hypertension (OR=1.47, 95% CI: 1.66-2.02, p=0.02) were major risk factors. A significant proportion of patients with left-sided disease had Caucasian ethnicity (p<0.001), while female gender, obesity, and iron deficiency anemia were also seen more frequently, although without statistical significance. Conclusion In the elderly (>75 years old), our study found hypertension to be associated with an increased risk of CD, while impaired fasting glucose (IFG) was protective. Most patients exhibited isolated left-sided diverticulosis, with pan-diverticulosis associated with higher proportions of adverse health indicators, including American Society of Anesthesiologists (ASA) score ≥3, IFG, hypertriglyceridemia, hypertension, and hypothyroidism. Further research with larger sample sizes in similar age groups is needed to expand upon these findings.

Abstract	Background OP-29 is a Centers for Medicaid and Medicare Services (CMS) measure to ensure that endoscopists recommend appropriate follow-up intervals after normal colonoscopy in average risk patients. Failure to report OP-29 compliance can adversely affect hospital quality star rating as well as reimbursement for health care. The aim of our quality improvement project was to improve OP-29 compliance to the top decile over three years. Methodology Our sample included patients between 50-75 years of age who received average risk screening colonoscopies with normal findings. We provided intensive education to endoscopists about the importance of OP-29 compliance, developed an Epic Smartlist that directs our endoscopists to list an appropriate reason for colonoscopy intervals other than 10 years, and monitored OP-29 compliance monthly. We became the first health network in the United States to implement the Lumens endoscopy report writing software (Epic Systems Corporation, Verona, USA) and added the OP-29-related Epic Smartlist to the Lumens colonoscopy note template. All statistical analyses were conducted in SPSS version 26 (IBM Corp., Armonk, USA) to compute the means and frequencies of outcomes. Results Our sample included 2,171 patients with a mean age of 60.5 years of whom the majority were female (57.2%) and Caucasians (90%). Our OP-29 score increased from 87.47% to 100% over the course of three years, and this steady improvement was seen broadly across our network. We compared our network score averages to our state and national averages and consistently demonstrated higher compliance rates while reaching the top decile by 2020. Conclusion We believe our improved OP-29 compliance has reduced colonoscopy overutilization, improved health care quality, and reduced health care costs for our patients and health network. To our knowledge, this is the first reported project towards improving OP-29 compliance utilizing the Epic Lumens software. Epic Lumens (Epic Systems Corporation, Verona, USA) added this Smartlist as quick buttons in the standard colonoscopy procedure note templates they built for other organizations to improve health care quality and cost nationally.

Abstract	BACKGROUND Autoimmune pancreatitis (AIP) is a rare, steroid-responsive disease of the pancreas. Concurrent treatment with immunosuppressants, including corticosteroids, increases the risk of developing a severe form of coronavirus disease 2019 (COVID-19) due to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) advises against the use of corticosteroids in patients with SARS-CoV-2 due to their poor outcomes in patients with SARS-CoV and Middle East respiratory syndrome (MERS-CoV), unless these patients require steroid treatment for a coexisting disease. CASE REPORT A 53-year old patient was admitted with symptoms and diagnostic findings consistent with AIP. Thorough etiological workup revealed an elevated IgG4 level of 361 mg/dL and significant clinical response to corticosteroid treatment, leading to a diagnosis of AIP. After finishing steroid treatment at home, the patient was readmitted with another episode of AIP complicated by development of acute necrotic collection and COVID-19 while taking a second course of high dose prednisone. The patient was continued on high dose prednisone, started on azathioprine and intravenous meropenem, and underwent CT guided percutaneous drainage. He also received supportive care for COVID-19. After significant clinical improvement, the patient was discharged to quarantine at home, which he completed uneventfully. CONCLUSIONS Despite the use of corticosteroids due to AIP, this high risk patient recovered from COVID-19 without complications. These findings support the use of corticosteroids when necessary for treatment of coexisting conditions in COVID-19 patients.

Abstract	BACKGROUND Plummer-Vinson syndrome is a rare disease that presents with iron-deficiency anemia, dysphagia, and esophageal webs. It usually occurs in middle-aged White women, and it increases the risk for esophageal cancer. The prevalence of Plummer-Vinson syndrome has decreased due to early detection of iron deficiency and repletion of iron stores. Although Plummer-Vinson syndrome has also been commonly described in children and adolescents, it is seldom reported in the elderly population. CASE REPORT An 88-year-old women with a history of mild cognitive impairment, allergic rhinitis, and gastroesophageal reflux disease presented with difficulty in swallowing solid foods. She had a decreased appetite, along with a 4.5-kg weight loss in the last 1 year. She was also found to have severe iron deficiency and mild anemia. Her dysphagia continued to progress even after starting iron supplementation for her iron deficiency. She eventually had a food bolus trapped in her cervical esophagus that required removal via esophagogastroduodenoscopy. A barium swallow revealed a narrowing in the upper esophagus. A repeat esophagogastroduodenoscopy revealed an esophageal web that was dilated, resulting in relief of symptoms. CONCLUSIONS Dysphagia is reported in up to 10% of the elderly population. It commonly causes malnutrition and is associated with increased mortality. The usual etiologies include cognitive dysfunction, neurological disorders, and/or esophageal dysmotility or narrowing. Although the incidence of Plummer-Vinson syndrome has decreased over time, the possibility of its presence should not be overlooked. To our knowledge, the current case is the third case of dysphagia related to Plummer-Vinson syndrome reported in an octogenarian in the literature so far. Iron replacement can help resolve dysphagia in Plummer-Vinson syndrome but dilation of esophageal webs may sometimes be required.

Abstract	There is a paucity of studies investigating the impact of chronic corticosteroid use for coexisting conditions in patients with Coronavirus Disease 2019 (COVID-19). Additionally, the information regarding the impact of chronic liver disease (CLD) on COVID-19 outcomes is evolving. Our study aims to investigate hospitalization outcomes of patients with COVID-19 on long term corticosteroids for coexisting conditions while also seeking to compare outcomes between such patients with a history of CLD to analyze the impact on mortality. We conducted a retrospective chart review across our 10-hospital network identifying patients on chronic corticosteroids (Prednisone ≥ 5 mg daily dose or equivalent dose of another steroid, for a duration of 30 days or more) who were hospitalized with COVID-19 from March 1, 2020 to June 30, 2020. Of these patients who met inclusion criteria, patients were then divided into groups based upon their history of CLD. Primary outcomes of the study looked to investigate the hospitalization outcomes of patients with a history of CLD and comorbid conditions requiring chronic corticosteroid use. Secondary outcomes sought to further investigate risk factors for mortality in our study sample. 837 charts were reviewed. 139 patients met inclusion criteria of which 34 patients had a history of CLD. Statistical analysis demonstrated no difference in length of hospital stay but increased ICU admission rate in the CLD group (41.2% vs 23.8%). No statistically significant difference was seen in between the CLD and non-CLD groups in term of complication rates and 28-day mortality. However, chronic corticosteroids patients were found to have higher rates of ICU admission and overall 28-day and ICU mortality in comparison to patients who were not on chronic corticosteroids prior to COVID-19 hospitalization. The larger contributor to COVID-19 severity was likely chronic corticosteroid use rather than CLD and thus chronic corticosteroid use should be limited throughout the COVID-19 pandemic especially in patients with additional speculated risk factors for COVID-19 such as CLD.
