Objectives: Although there have been associations between diabetes and mortality in COVID-19 patients, it is unclear whether this is driven by the disease itself or whether it can be attributed to an inability to exhibit effective glucose control. Methods: We conducted a retrospective cohort study of 292 patients admitted to a tertiary referral center to assess the association of mortality and glycemic control among COVID-19-positive patients. We used a logistic regression model to determine whether average fasting glycemic levels were associated with in-hospital mortality. Results: Among the diabetic and non-diabetic patients, there were no differences between mortality or length of stay. Mean glucose levels in the first 10 days of admission were higher on average among those who died (150–185 mg/dL) compared with those who survived (125–165 mg/dL). When controlling for multiple variables, there was a significant association between mean fasting glucose and mortality (odds ratio = 1.014, p < 0.001). The associations between glucose and mortality remained when controlled for comorbidities and glucocorticoid use. Conclusion: The results of this retrospective study show an association between mortality and inpatient glucose levels, suggesting that there may be some benefit to tighter glucose control in patients diagnosed with COVID-19.

• Breast biopsy marker migration is documented in 13% of 268 procedures. • Marker migration is affected by physical, biological, and pathological factors. • Breast density, marker shape, needle approach etc. affect migration. • Study demonstrates marker migration prevalence; marker design improvements are needed.

Left ventricular thrombus (LVT) is a major complication of acute myocardial infarction (MI). Here, we describe the case of a 36-year-old female with a history of acute anterior MI six years prior to hospitalization, who presented with bilateral vision loss due to a bilateral embolic posterior cerebral artery (PCA) stroke in the setting of a 5.7 x 1.7 cm LVT. She underwent bilateral PCA thrombectomy, which led to improvement of her symptoms. Her LVT was managed non-surgically with apixaban and clopidogrel. Her case highlights the need for more medical education about LVT, as quick initiation of anticoagulation is essential in improving outcomes. We review the existing literature to explain the pathogenesis, diagnosis, and treatment of LVT.

Gallbladder disease and peptic ulcer disease (PUD) can present very similarly, and misdiagnosis can often result because of conflicting symptoms. PUD in pregnancy is relatively rare, in part due to the changes in estrogen and progesterone levels. We present a case of a postpartum female, post operation Day 5, with signs/symptoms, physical exam and laboratory work consistent with acute cholecystitis that was found to have a perforated duodenal ulcer intraoperatively. The authors suggest that a fistula would have resulted with ongoing disease. Bilio-enteric fistulas can often form due to ongoing cholelithiasis disease. Cholecystoduodenal fistulas (CDFs) are the most common fistulas to present. It is possible that the incidence of CDF formation secondary to perforated duodenal ulcers is underestimated due to signs and symptoms not presenting until gallstone ileus is diagnosed.

Our patient is a 47-year-old African American female with a past medical history of recurrent episodes of small bowel obstruction. She presented to the emergency department with symptoms of nausea, vomiting, and abdominal pain. Upon further evaluation, imaging showed obstruction at the terminal ileum. Based on the holistic clinical presentation, we initially thought that this patient was experiencing symptoms of early onset Crohn’s disease. Gastroenterology evaluated the patient and was uncertain of the formal diagnosis. Colonoscopy and biopsy were not pathognomonic for Crohn’s disease, suggesting that there may be a component of terminal ileitis or another inflammatory bowel disease process. This case exemplifies the degree to which these inflammatory bowel disease processes frequently overlap.
