Abstract

To assess the health and cost effects of a patient's risk-taking attitudes about diagnostic tests. Cost-effectiveness analysis. Diagnostic testing strategies used in the evaluation of a patient with a radiographically detected lung lesion were evaluated. Strategies included combinations of sputum, fine-needle aspiration, bronchoscopy, thoracoscopy, and expectant management. Patient data were obtained from the Survival Epidemiology and End Results Program, MEDLINE search, National Center for Health Statistics, and the Universities of Iowa and Stanford, and Kaiser Permanente Hospital. Different patient risk-taking attitudes were simulated using decision analysis. Lifetime cost of medical care, life expectancy, and cost effectiveness. The cost effectiveness of competing strategies depended on patient attitudes about taking risks. For a patient averse to expectantly waiting without definitive knowledge of whether cancer was or was not present, testing strategies using invasive procedures, such as thoracoscopy, were more cost effective. In contrast, for a patient who was identical except that he or she was averse to tests with higher morbidity and mortality, strategies that involved expectantly waiting, instead of more invasive test...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
