Abstract

Paediatric laparoscopic procedures are now becoming routine practice. Therefore, there is a need for simulated laparoscopic models to acquire part-procedural competency prior to direct patient contact in a safe learning environment. For this reason, we chose two paediatric conditions; inguinal hernia (IH) and congenital diaphragmatic hernia (CDH), which were combined to create the laparoscopic inguinal and diaphragmatic defect (LIDD) model. Our aim was to assess this novel surgical simulation model by determining its construct and content validity. A total of 107 participants completed the validation study: volunteer medical students (novices), surgical trainees (intermediate) and consultant surgeons (experts). Basic demographic data were collected. Subjects were shown a pre-recorded video of both exercises. The assessment exercise involved closing both the simulated inguinal or diaphragmatic hernial orifice. The task was assessed using a novel scoring system with a maximum score of 21 for IH model and 15 for the CDH. The content validity was assessed by a 6-point Likert scale of the expert group. 105/107 participants successfully completed the two exercises. Both aspects of the LIDD model revealed a statistical significance be...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.
