Immune Checkpoint Inhibitor-Induced Hemorrhagic Gastritis.

Immune checkpoint inhibitors (ICIs) have been increasingly used in the treatment of several malignancies and may target cytotoxic T-lymphocyte-associated antigen-4, programmed cell death-1, and programmed cell death ligand 1, which work on maintaining peripheral immune tolerance. ICIs inhibit these ligands causing an immune-enhancing effect, leading to a wide spectrum of complications from mild mucositis to life-threatening pneumonitis or hepatitis. These complications are collectively called immune-related adverse events.

Natural history, clinical course and predictors of interval time from initial diagnosis to development of subsequent NSCLC brain metastases.

Purpose: Non-small cell lung cancer (NSCLC) brain metastases are associated with substantial morbidity and mortality. During recent years, accompanying dramatic improvements in systemic disease control, NSCLC brain metastases have emerged as an increasingly relevant clinical problem. However, optimal surveillance practices remain poorly defined.

Is Anacetrapib Better Than Its CETP Inhibitor Counterparts?

Cholesterol metabolism and transport has been a major focus in cardiovascular disease risk modification over the past several decades. Hydroxymethylglutaryl-CoA reductase inhibitors (statins) have been the most commonly used agents, with the greatest benefit in reducing both the primary and secondary risks of cardiovascular disease. However, heart disease remains the leading cause of death in both men and women in the United States.

Single institution validation of a modified graded prognostic assessment of patients with breast cancer brain metastases.

Aim: The number of breast cancer brain metastases is a prognostic clinical variable in the modified graded prognostic assessment (GPA) Index for breast cancer.

Patients & Methods: We retrospectively gathered data from 127 breast cancer patients who underwent radiation therapy for brain metastasis. Patients were stratified by both breast GPA and modified breast GPA scores, and survival was determined using the Kaplan-Meier curves and Cox proportional hazards model.

Breast cancer subtype and stage are prognostic of time from breast cancer diagnosis to brain metastasis development.

Breast cancer brain metastasis (BCBM) is associated with high morbidity and mortality. Patients with breast cancer risk factors associated with rapid development of BCBM could potentially benefit from early brain metastasis screening. We retrospectively reviewed all BCBM patients treated with brain radiotherapy at our institution from 1997 to 2015.

Whole-brain Irradiation Field Design: A Comparison of Parotid Dose.

Whole-brain radiation therapy (WBRT) plays an important role in patients with diffusely metastatic intracranial disease. Whether the extent of the radiation field design to C1 or C2 affects parotid dose and risk for developing xerostomia is unknown. The goal of this study is to examine the parotid dose based off of the inferior extent of WBRT field to either C1 or C2.

Single Grain Boundary Modeling and Design of Microcrystalline Si Solar Cells.

For photovoltaic applications, microcrystalline silicon has a lot of advantages, such as the ability to absorb the near-infrared part of the solar spectrum. However, there are many dangling bonds at the grain boundary in microcrystalline Si. These dangling bonds would lead to the recombination of photo-generated carriers and decrease the conversion efficiency.
