    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    You probably can still find some magnetic tapes and CDs somewhere deep in your closet. They are precious memories that you want to keep, but I'm 90 percent sure that you've already thrown the media player away. When we talk about digital preservation, we have to know that the digital containers are as important as the files. I took this picture in New York Public Library, its Microforms Reading Room has the collection of over 350,000 microfilm reels and 3,000,000 microfiche covering a variety of humanities and social sciences subjects. People can read newspapers in 19th century through the ancient microfilm scanner. Nowadays, many products read old versions, but do they fully support them? Can people preserve old version software to read past files? Yes, you might have the media, but do you have the player?Ope

    Pricing strategies for new product and remanufactured product considering emission sensitive demand.

    With the rapidly increasing concern on environmental pollution and resource shortage, remanufactured products attract many attentions. In order to determine the optimal production and pricing strategy, we construct decision models for both single-product market and mixed-product market. Consumers' different preferences for new products and remanufactured products are considered. First, we construct pricing models for a single-product market, and achieve a judging condition to determine the optimal strategy. Second, we develop a pricing model for a multiple-product market and put forward a suppose to show that the multiple-product strategy is not always optimal. Finally, numerical illustrations are designed to examine the impacts of the two crucial factors and obtain the dominant regions for each strategy. By introducing an emission sensitive demand, we show the superiority of the remanufactured product when the extra demand attracted by the emission saving is large

    Surface display of OmpC of Salmonella serovar Pullorum on Bacillus subtilis spores.

    Salmonellosis is a major public health problem throughout the world. Thus, there is a huge need for diversified control strategies for Salmonella infections. In this work, we have assessed the potential use of Bacillus subtilis (B. subtilis) spores for the expression of a major protective antigen of Salmonella serovar Pullorum, OmpC. The expression of OmpC on the surface of spores was determined by immunofluorescence microscopy. Mice immunized with recombinant spores expressing the OmpC antigen presented significant levels of OmpC-specific serum IgG and mucosal SIgA antibodies than in mice immunized with non-recombinant spores (p<0.01). In addition, oral immunization with recombinant spores was able to induce a significant level of protection in mice against lethal challenge with Salmonella serovar Typhimurium. These results suggest that B. subtilis spores have promising potential in the development of mucosal vaccines against Salmonella infections
