Development of the Oncology Opportunity Cost Assessment Tool: Item Generation and Content Validity Testing.

Purpose: The purpose of this study was to develop the Oncology Opportunity Cost Assessment Tool (OOCAT), a survey instrument to evaluate the opportunity costs patients experience when seeking medical oncology care.

Methods: Development of the OOCAT involved extensive patient engagement through both focus groups and interviews. First, the study team developed a list of opportunity cost concepts, which included patients' logistical and financial considerations related to seeking care.

Application of medical cannabis in unstable angina and coronary artery disease: A case report.

Rationale: First discovered in 1990, the endocannabinoid system (ECS) was initially shown to have an intimate relationship with central areas of the nervous system associated with pain, reward, and motivation. Recently, however, the ECS has been extensively implicated in the cardiovascular system with contractility, heart rate, blood pressure, and vasodilation. Emerging data demonstrate modulation of the ECS plays an essential role in cardio metabolic risk, atherosclerosis, and can even limit damage to cardiomyocytes during ischemic events.

Intracolonic Administration of Vancomycin in Intensive Care Unit Patients with Severe Clostridium Difficile Colitis.

Background: Clostridium difficile infection (CDI) is a major cause of antibiotic-associated diarrhea worldwide. The incidence of sepsis has been shown to be increasing due to severe or fulminant colitis. Oral vancomycin is the treatment of choice for CDI, but it is often ineffective in patients in the intensive care unit (ICU) due to poor intestinal motility.

Inflammaging and Oxidative Stress in Human Diseases: From Molecular Mechanisms to Novel Treatments.

It has been proposed that a chronic state of inflammation correlated with aging known as inflammaging, is implicated in multiple disease states commonly observed in the elderly population. Inflammaging is associated with over-abundance of reactive oxygen species in the cell, which can lead to oxidation and damage of cellular components, increased inflammation, and activation of cell death pathways. This review focuses on inflammaging and its contribution to various age-related diseases such as cardiovascular disease, cancer, neurodegenerative diseases, chronic obstructive pulmonary disease, diabetes, and rheumatoid arthritis.

Interplay between ROS and Antioxidants during Ischemia-Reperfusion Injuries in Cardiac and Skeletal Muscle.

Ischemia reperfusion (IR), present in myocardial infarction or extremity injuries, is a major clinical issue and leads to substantial tissue damage. Molecular mechanisms underlying IR injury in striated muscles involve the production of reactive oxygen species (ROS). Excessive ROS accumulation results in cellular oxidative stress, mitochondrial dysfunction, and initiation of cell death by activation of the mitochondrial permeability transition pore.

Reactive Oxygen Species in COPD-Related Vascular Remodeling.

The pathogenesis of chronic obstructive pulmonary disease (COPD) is a multifaceted process involving the alteration of pulmonary vasculature. Such vascular remodeling can be associated with inflammation, shear stress, and hypoxia-conditions commonly seen in patients with lung diseases. Particularly, the overproduction of reactive oxygen species (ROS) in the diseased lungs contributes greatly to pulmonary vascular remodeling.
