To describe critical tasks and errors associated with intercostal chest drain insertion, in order to develop enhanced procedural guidelines for task performance and training. ⋯ Tasks and sub-tasks associated with intercostal chest drain insertion was described and evaluated for criticality. The most critical task was the correct identification of a safe insertion point. Applications include development of procedural guidelines with tasks vulnerable to error highlighted and training interventions that promotes safe task performance.

Several studies demonstrated potential associations between the telomere length (TL) in leukocytes and psoriasis or psoriatic arthritis (PsA). This study aimed to investigate whether there was the causal genetic relationship between TL and psoriatic diseases bidirectionally. ⋯ This MR study revealed an association between genetic indicators of shortened TL and risk of overall psoriasis and PV, and genetic predisposition to PsA was associated with longer TL. Key message What is already known on this topic? Telomere length (TL) is acknowledged to reflect an individual's biological age but is also associated with dysregulated immune function and immunosenescence. The impact of aging on psoriasis is controversial. Existing evidence suggests that aging may influence pathological changes and clinical course but whether aging is an independent risk factor remains unclear. What this study adds? The current study found an association between genetic indicators of shortened TL and the risk of overall psoriasis and psoriasis vulgaris (PV). There was a bidirectional link between genetically indicated overall psoriasis and shortened TL. A possible positive genetic association between PsA and TL was also found. How this study might affect research, practice, or policy? Our study may provide evidence for TL as new diagnostic and therapeutic strategies in clinical practices for psoriasis. Greater efforts to psoriasis management may substantially reduce the aging attributable to TL shortening. Future large-scale GWAS and experimental studies are warranted to examine the mechanistic basis for links between TL and psoriasis to improve understanding and illuminate possible therapeutic targets for psoriatic disease.
