Abstract

To assess the domain structure and to evaluate the psychometric properties of the Cancer Therapy Satisfaction Questionnaire (CTSQ) and the relation between the CTSQ and health-related quality of life (HRQOL). Three hundred sixty-one individuals with breast, colorectal, lung cancer, or melanoma who had received in the last 6 months or were currently receiving more than one cycle of chemo, biological, or hormonal therapy completed the 21-item CTSQ, with a random subsample of 88 patients completing it again 1 week later. Participants also completed quality of life, treatment satisfaction, and other self-reported questions on each occasion. Demographics, ECOG performance status, and clinical information were collected. CTSQ responses were submitted to multitrait analyses and exploratory factor analysis. Psychometric properties and the correlations between the CTSQ and the Quality of Life Questionnaire -- Core 30 (QLQ-C30) were evaluated. Analyses revealed three domains with good psychometric properties: Feelings about Side Effects, Satisfaction with Therapy, and Expectations of Therapy. Correlations with the QLQ-C30 domains were low to moderate. The CTSQ is a newly developed 16-item patient-reported measure with strong psychometric...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.
