Background: During the course of the COVID-19 pandemic, nasopharyngeal swabs, combined throat and nose swabs and saliva samples have been evaluated for SARS-CoV-2 detection using nucleic acid amplification tests (NAT). Literature on anterior nasal swabs is limited. We investigated a novel anterior nasal swab that has been designed to standardised self-collection, maximise sample uptake and improve user comfort.

Recruitment of children into clinical trials is challenging. Most systematic reviews exploring facilitators and barriers of child recruitment in clinical trials are related to drugs or experimental treatments for various health conditions. This may differ in nutrition, physical activity, and obesity interventions.

Smoking cigarettes with substantially lower nicotine than conventional cigarettes prior to a quit attempt may reduce the reinforcing effects of smoking, which could facilitate smoking cessation through extinction learning. This paper describes the development of a smoking cessation intervention designed to optimize extinction processes using reduced nicotine cigarettes, as well as the design and methods for an ongoing randomized controlled trial (RCT) to evaluate this intervention. Qualitative methods and pilot testing were conducted to develop the novel facilitated extinction (FE) intervention, with a key focus on maximizing opportunities for extinction learning during a five-week pre-quit period.

Despite a growing number of ion channel genes implicated in hereditary ataxia, it remains unclear how ion channel mutations lead to loss-of-function or death of cerebellar neurons. Mutations in the gene , encoding the α-subunit of the BK channel have emerged as responsible for a variety of neurological phenotypes. We describe a mutation (BK) in , in a child with congenital and progressive cerebellar ataxia with cognitive impairment.
