Background: Transient elastography (TE) is an FDA approved, non-invasive tool to estimate liver stiffness measurement (LSM) in patients with non-alcoholic fatty liver disease (NAFLD). Our aim was to analyze if body mass index (BMI) would predict the severity of liver stiffness using TE scores.Methods: We performed a cross-sectional study of patients with NAFLD who presented to the hepatology clinic between January 2019 through January 2021. Fibrosis severity was divided into the following categories: F0 to F1 (2-7 kPa), F2 (>7 to 10 kPa), F3 (>10 to 14 kPa) and F4 (>14 kPa). We used ordered logistic regression models to determine the odds ratio (OR) and 95% confidence interval (CI) of having a higher LSM severity compared to lower associated with BMI. Models were adjusted for patient demographics and comorbidities.Results: Among 284 patients, 56.7% were females, and the median (interquartile range, IQR) age was 62 [51-68] years and BMI 31.9 (28.1, 36.2) kg/m 2 ; 47% of patients were in the F0 to F1 stage, 24% F2, 16% F3, and 13% F4. The correlation between BMI and TE score was 0.31 (P<0.001). With 1 kg/m 2 increase in BMI there was 1.10 times higher odds of having a higher LSM severity (adjusted OR, 1.10; 95% CI: 1.05-1.14).Compared to patients with BMI <25 kg/m 2 , the adjusted OR (95% CI) of having a higher fibrosis stage was 1. 82 (0.61-5.44), 5.93 (2.05-17.13), and 8.56 (2.51-29.17) for patients with BMI of 25 to <30, 30 to <40, and ≥40 respectively. Conclusions: BMI correlates with the severity of LSM using TE scores in NAFLD patients even after adjusting for potential confounding variables. This suggests TE as an appreciable study for liver stiffness even in obese individuals.

A 33-year-old previously healthy man from Mexico who presented with massive hemoptysis, fevers, chills and found to have cavitary lesions in the right upper lobe of lung was highly suspicious for tuberculosis. The patient was treated with vancomycin, ceftriaxone, azithromycin and placed on isolation for suspected tuberculosis. Sputum AFB stains were negative and blood cultures grew Group A Streptococcus [GAS]. Antibiotics were narrowed down to ampicillin-sulbactam and the patient was discharged with significant clinical improvement. Strep A pyogenes is a rare cause of cavitary hemorrhagic pneumonia but is associated with high mortality. Clinical suspicion and early diagnosis are crucial in saving the patient.

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare, rapidly progressive, primary intestinal T-cell lymphoma. It is most commonly seen in the Asian and Hispanic populations and is usually not related to celiac disease, unlike type I enteropathy associated Tcell lymphoma. The most common site of occurrence is the small intestine. Patients usually present during the advanced stage of disease with clinical features of intestinal perforation or obstruction. The late clinical presentation and lack of targeted therapy are factors contributing to its poor prognosis. Here, we are presenting the case of a patient who initially came to the hospital for a urinary tract infection. As his abdominal CT scan showed abdominal wall thickening, he underwent further workup which revealed the diagnosis of MEITL.
