Time Spent per delta PASI (TSdP) among psoriasis patients undergoing UVB-therapy - A pilot study

Abstract

Psoriasis often poses a significant challenge to treat. Ultraviolet light band (UVB) treatment is widely used and well recognized. However, the frequent visits to the dermatologist may indirectly present an impediment to many of the patients' careers and every day life due to the vast time burden with subsequent lost work earnings. We investigated the cost-effectiveness of the psoriasis UVB treatment from a patient's point of view using time as a surrogate measure. Twenty-five patients participated (17 males and 8 females) in the study. We registered the number of UVB treatments per patient as well as the patients PASI (psoriasis area and severity index) score at each treatment session. The time spent in relation to each treatment session was reported in a questionnaire given to the patient. Time Spent per delta PASI (TSdP) was defined as number of minutes to reduce the PASI score by one. Seventeen (68%) of the participants needed less than 300 min to lower the PASI with one score. The rest (n = 7 (32%)) used more than 300 min to lower the PASI score by one. Thus, the TSdP distribution displayed two peaks; ><300 min/dPASI. Log-transformed linear regression model showed that the expected TSdP would decrease with 42% for each tim...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.
