DIRAS3 enhances RNF19B-mediated RAC1 ubiquitination and degradation in non-small-cell lung cancer cells.

Distant metastasis remains the leading cause of high mortality in patients with non-small-cell lung cancer (NSCLC). DIRAS3 is a candidate tumor suppressor protein that is decreased in various tumors. However, the regulatory mechanism of DIRAS3 on metastasis of NSCLC remains unclear.

Difficulty in Diagnosing Rare Cardiac Tumors: A Case Series.

Primary cardiac tumors are rare because metastatic lesions from distant sites account for most masses. We are reporting two cases of malignant intracardiac masses with their diagnostic dilemma. Our first patient is a 72-year-old male with a pertinent history of desmoplastic and spindle cell melanoma who presented after his surveillance positron emission tomography (PET) scan showed a hypermetabolic lesion in the inferior pericardium.

Diagnosing Intravascular Large B-Cell Lymphoma: A Tale of Hide and Seek.

We are reporting the first documented case of intravascular large B-cell lymphoma (IVLBCL) manifesting in the endomysial and perimysial capillaries with its associated diagnostic dilemma. Our patient presented with progressive paraplegia. Initial laboratories were remarkable for hyponatremia, hypochloremia, lactic acidosis, elevated C-reactive protein, and lactate dehydrogenase.

Pembrolizumab-Associated Seronegative Myasthenia Gravis in a Patient With Metastatic Renal Cell Carcinoma.

Seronegative myasthenia gravis is a rare, but potential adverse effect of immune checkpoint inhibition. There have been few but increasing number of cases reported in recent years, and early recognition is important for prompt diagnosis and management. Here, we describe the case of a 65-year-old male with metastatic renal cell carcinoma on pembrolizumab diagnosed with new-onset seronegative myasthenia gravis and review literature on its management.

When the Tumor Lyses: A Case Report on Spontaneous Tumor Lysis Syndrome.

Tumor lysis syndrome (TLS) is an oncological emergency characterized by severe electrolyte disturbance that typically occurs when hematologic cancer patients have been started on systemic chemotherapy. We present an uncommon case of spontaneous TLS (STLS) occurring in a patient with cholangiocarcinoma. The patient was a 59-year-old male with newly diagnosed differentiated carcinoma of unknown origin who presented with weakness, fatigue, and lightheadedness.

Potential Savings from Visit Reduction of Continuous Intraocular Pressure Monitoring.

Introduction: A continuous method of measuring intraocular pressures (IOP) could be advantageous in the management of glaucoma. This report aims to analyze the potential savings from visit reduction of continuous IOP measurements obtained with an intraocular device.

Materials And Methods: We constructed a model adapted from a prior study based on the number of glaucoma patients among 5% of the Medicare population.

Encapsulated Bifidobacteria reduced bacterial translocation in rats following hemorrhagic shock and resuscitation.

Objective: The aim of the present study was to determine the effects of peroral encapsulated Bifidobacteria on intestinal microflora, bacterial translocation (BT), plasma endotoxin, and ileal villi injury in a rat model of hemorrhagic shock.

Methods: Sprague-Dawley rats were fed daily with three different diet supplements: phosphate buffered saline, Bifidobacteria (10(9) colon-forming units/day), or microencapsulated Bifidobacteria (10(9) colony-forming units/day). After 7 d of treatment, rats were anesthetized for hemorrhagic or sham shock.
