The Stop the Bleed (STB) course teaches trainees prehospital hemorrhage control with a focus on mass education. Identifying populations most likely to benefit can help save on the significant cost and limited resources. In this study, we attempted to identify those populations and performed a cost analysis. Trainees underwent STB education and completed a survey on completion to assess demographics and prior experiences where STB skills could have been useful. Five hundred seventy-one trainees categorized as first responders (14%), students (56%), and the working public (30%) completed the survey. Most trainees found the lecture and simulation helpful, 96 per cent and 98 per cent, respectively. There were significant differences among groups who had previously been in situations where the STB course would have been helpful (88% first responders 40% students 43% public workers) ( < 0.001). Teaching a class of 10 students costs approximately $455; the cost can be as high as $1246 for a class of 50 students. Most STB trainees found the course helpful. First responders are most likely to be exposed to situations where course information could be helpful. Focusing on specific high-yield groups rather than mass education might be a more efficient approach to STB education.

This work aims to address key issues in the ballistic performance of ceramic-based composite armor, particularly at the joints of spliced bulletproof panels. The edge structure of C/C-SiC ceramic plates and ultra-high molecular weight polyethylene is redesigned to superimpose the joint areas. These structurally optimized composite pads are examined by numerical simulation of impact dynamics to understand their anti-penetration performance whose accuracy is then validated by live fire tests.

Moyamoya disease (MMD) is a progressive cerebrovascular disorder that increases the risk of intracranial ischemia and hemorrhage. Timely diagnosis and intervention can significantly reduce the risk of new-onset stroke in patients with MMD. However, the current diagnostic methods are invasive and expensive, and non-invasive diagnosis using biomarkers of MMD is rarely reported.

Associations of adiposity with risks of oesophageal squamous cell carcinoma (ESCC) and non-cardia stomach cancer, both prevalent in China, are still inconclusive. While adiposity is an established risk factor for colorectal cancer, the relevance of fat-free mass and early-adulthood adiposity remains to be explored. The prospective China Kadoorie Biobank study included 0.

Introduction/aims: We aimed to determine differences in diaphragm thickness by including/excluding pleural and peritoneal membranes, the variability in diaphragm thickness over the apposition zone, and the predictors of diaphragm thickness and excursion measurements.
Methods: At least 10 male and female subjects were recruited for each decade of life. Spirometry, respiratory muscle strength, and the diaphragm ultrasound (US) measurements were performed.
