Abstract

This study aimed to determine the validity and reliability of the Delirium Knowledge Test for the Intensive Care Nurse. The item analysis and reliability of the test was assessed in a sample of 274 nurses working in the internal and surgical adult intensive care units of one public and three university hospitals in Turkey between 15 May and 15 August 2017. Content and face validity, item analysis and reliability coefficients were used to evaluate the psychometric properties of the test. The item difficulty index and item discrimination index of the questions included in the draft form of the 40-item test were found to range from 0.22 to 0.93 and from 0.06 to 0.51, respectively. At the end of the analyses, 14 items were excluded from the draft test, 11 according to the item difficulty index and 3 according to the item discrimination index. Correspondingly, the final version of the test consisted of 26 questions. The item difficulty index of the final test was 0.22 to 0.79, and the item discrimination index was 0.20 to 0.51. The difficulty level of the final test was found to be 59%, and the Cronbach's alpha reliability coefficient was 0.83. The results of the study showed that the test had good content and face validity and reli...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.
