Background & Aims: Noninvasive variceal risk stratification systems have not been validated in patients with hepatocellular carcinoma (HCC), which presents logistical barriers for patients in the setting of systemic HCC therapy. We aimed to develop and validate a noninvasive algorithm for the prediction of varices in patients with unresectable HCC.

Methods: We performed a retrospective cohort study in 21 centers in the United States including adult patients with unresectable HCC and Child-Pugh A5-B7 cirrhosis diagnosed between 2007 and 2019.

Background: Studies evaluating the role of midodrine as an adjunctive therapy to liberate patients with shock from intravenous (IV) vasopressors have yielded mixed results. The aim of our study was to evaluate the efficacy and safety of midodrine as an adjunctive therapy to liberate patients with shock from IV vasopressors.

Methods: Electronic searches of the MEDLINE, EMBASE, and Cochrane databases through April 2022 for randomized controlled trials (RCTs) that evaluated the use of midodrine versus control in patients with shock and a low dose of IV vasopressors.

Central diabetes insipidus (DI) is an uncommon condition caused by reduced or lack of vasopressin secretion from the posterior pituitary gland, typically caused by gland destruction. Several other causes for central DI have also been proposed. Here we present a case of transient central DI after discontinuation of vasopressin used for septic shock without evidence of overt pituitary damage in a cystic fibrosis patient.

Patients with cardiac disease frequently develop pleural effusions; the incidence is approximately 500,000 cases per year in the United States. These effusions often represent important clinical events for patients, indicating that either there has been an acute change in the patient's clinical status or the patient's chronic management program needs review. These effusions usually develop in both the right and left hemithorax but can be unilateral.

Background: A critical and unmet therapeutic need is the prompt and reliable exclusion of acute myocardial infarction (AMI), which would allow for prompt discharge from the emergency department. High-sensitivity troponin (HS-TnT) combined with copeptin has been proposed to expedite the diagnostic exclusion of AMI in addition to its predictive usefulness in the intermediate and long-term outcomes of AMI. The European Society of Cardiology recommends the Global Registry of Acute Coronary Events (GRACE) as a prognostic score to manage acute coronary syndrome (ACS) without ST segment elevation.

Background: Clinicians often utilize off-label dose escalation of ustekinumab (UST) in Crohn's disease (CD) patients with disease refractory to standard dosing. Previous studies report mixed results with dose escalation of UST.

Methods: A retrospective observational study of 143 adult patients with CD receiving UST over a 33-month time period was conducted.

Extra-adrenal pheochromocytoma is uncommon and usually secreting nor-epinephrine. We are presenting a possible case of extra-adrenal pheochromocytoma in a 68-year-old male who was admitted to Queens Hospital Center complaining of shortness of breath for two days. Physical examination was unremarkable except tachycardia.

Sarcomatoid carcinomas, also known as spindle cell carcinomas (SPCCs), are rare carcinomas, predominantly developing in the lung. They have lots of features of sarcoma in their histological features. The standard laryngeal carcinoma classification is based on tumor size, lymph node affection, and metastasis (TNM), it is the classification scheme of the American Joint Committee on Cancer Staging (AJCC), and it is used in the same way for stage spindle cell carcinoma (SPCC).
