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.

Physical activity was previously associated with decreased mortality. Current guidelines recommend >150 min/week or >75 min/week of moderate or high-intensity exercise to maintain a healthy lifestyle; however, exercise properties most strongly associated with low mortality among the elderly may still be explored. ⋯ The study further supports current exercise guidelines among the elderly. It also underscores the importance of physical activity in older individuals while prioritizing a greater number of sessions/week in addition to the total duration, and highlights specific activity features associated with lower long-term mortality among older adults. Key message • What is already known on this topic - Physical activity was associated with a lower risk for mortality, although the specific properties and the preferred type of exercise among older adults are still debatable. • What this study adds - The study suggests the optimal activity characteristics in older adults while prioritizing activity sessions over time, light-moderate exercise over strenuous activity, diverse activity, and walking and swimming over other activities. • How this study might affect research, practice or policy - Future exercise guidelines should focus on increasing activity sessions throughout the week and not on the cumulative time to maximize the effect on mortality.

To systematically review the effect of vitamin D supplementation on diabetic foot ulcer (DFU) healing. ⋯ The current evidence suggests that vitamin D supplementation can significantly promote DFU healing by lowering blood sugar and alleviating inflammation and oxidative stress. Key messages What is already known on this topic Diabetic foot ulcer (DFU) is a major complication of diabetes mellitus, with high morbidity, mortality and resource utilization. Vitamin D has the effect of lowering blood sugar, improving insulin sensitivity, and increasing anti-inflammatory response. Clinical research on vitamin D supplementation for the treatment of DFU is increasing, but due to the lack of combing and integration, the actual efficacy of vitamin D in patients is unclear. What this study adds This meta-analysis has shown that vitamin D supplementation can significantly promote DFU healing by lowering blood glucose and alleviating inflammation and oxidative stress. How this study might affect research, practice or policy This study preliminarily found the effectiveness of vitamin D supplementation on the healing of DFU, which can provide a reference for the treatment of DFU by medical staff.
