Objective Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk.Methods This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate.Results With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3.Conclusion Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.

Water lettuce (Pistia stratiotes) is one of the most well-known aquatic weeds as it causes problems in watercourses all over the world. This invasive species is fast-growing and thus has the potential for its use in preparing growth medium of microorganisms. Toward it, the pretreatment and enzymatic saccharification are positively the decisive processes. But there are other crucial processes, which are usually ignored by researchers. To the best of my knowledge, this presented work is the first time discovering that the juice obtained from water lettuce is valuable. Except for sterilization, no treatment is needed for the water lettuce’s juice and it can be directly served for cell growth. For Escherichia coli, Saccharomyces cerevisiae, Pichia pastoris, Bacillus subtilis, Lactococcus Lactis, Lactobacillus rhamnosus, and Lactobacillus plantarum, the cell density in the broth of water lettuce’s juice as the only carbon source is 10-60% higher than that in LB, YPD, BHI, M17, MRS. We then examined the production of microbial lipid by YM prepared in the juice of water lettuce. In comparison to commercial medium YM broth, the YM with juice caused 84% increase in the production of microbial lipid. A simple process of collecting juice notably increased productivity.
