Abstract

The Virtual Reality Functional Capacity Assessment Tool (VRFCAT) is an "applied" game-based assessment that uses a multi-level functional task to assess instrumental activities of daily living (iADL). This study examines the feasibility, convergent validity, and predictive ability of the VRFCAT in a sample of inpatients with chronic schizophrenia. Inpatients with a DSM-5 diagnosis of schizophrenia or schizoaffective disorder, completed the VRFCAT prior to discharge. The UPSA-B, SLOF, and PSP were administered, both at baseline and after four-weeks in the community. VRFCAT performance scores were compared to published data from the VRFCAT validation study. All 62 participants completed the VRFCAT. Compared to the performance of stable outpatients, participants performed 1.50 SDs below the VRFCAT mean adjusted total time (ATT) (Validation study: Mean T Score = 32.5, SD = 16.59) with more errors. The VRFCAT ATT T-score was significantly correlated with baseline UPSA-B total score (p = 0.005) and PSP Global score (p = 0.010). 34 participants completed the follow-up period (55%), and 28 were lost to follow-up. There were no statistically significant differences in VRFCAT scores between these two groups (all p > 0.29). The VRFCAT com...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.
