Introduction Dementia is currently one of the leading causes of mortality globally, and mortality due to dementia will likely increase in the future along with corresponding increases in population growth and population aging. However, large inconsistencies in coding practices in vital registration systems over time and between countries complicate the estimation of global dementia mortality. Methods We meta‐analyzed the excess risk of death in those with dementia and multiplied these estimates by the proportion of dementia deaths occurring in those with severe, end‐stage disease to calculate the total number of deaths that could be attributed to dementia. Results We estimated that there were 1.62 million (95% uncertainty interval [UI]: 0.41–4.21) deaths globally due to dementia in 2019. More dementia deaths occurred in women (1.06 million [0.27–2.71]) than men (0.56 million [0.14–1.51]), largely but not entirely due to the higher life expectancy in women (age‐standardized female‐to‐male ratio 1.19 [1.10–1.26]). Due to population aging, there was a large increase in all‐age mortality rates from dementia between 1990 and 2019 (100.1% [89.1–117.5]). In 2019, deaths due to dementia ranked seventh globally in all ages and fourth among individuals 70 and older compared to deaths from other diseases estimated in the Global Burden of Disease (GBD) study. Discussion Mortality due to dementia represents a substantial global burden, and is expected to continue to grow into the future as an older, aging population expands globally.
ObjectivesThe aim of the current study was to investigate the effectiveness and clinical feasibility of Biyeom‐go for the treatment of nasal symptoms associated with rhinitis.DesignProspective observational study.SettingThis study was conducted at the Woosuk Korean Medicine Medical Center in South Korea.ParticipantsFifty‐eight patients with rhinitis participated in this study. All patients received Biyeom‐go treatment >3 times daily for a total of 4 weeks.Main outcome measuresThe primary outcome was the total nasal symptom score. Mini‐rhinoconjunctivitis quality of life questionnaire, nasal endoscopy index, total serum immunoglobulin E levels and immunologic factors in nasal lavage fluid were also measured.ResultsBiyeom‐go administration was associated with significant improvements in total nasal symptoms scores (P < .0001) and mini‐rhinoconjunctivitis quality of life questionnaire scores (P < .0001) in a time‐dependent manner. The nasal endoscopy index also significantly improved at weeks 2 (P = .0049), 3 (P < .0001) and 4 (P = .0001) after Biyeom‐go treatment. Significantly, increased interleukin‐2 levels (P = .005) and decreased interleukin‐8, chemokine (C‐C motif) ligand (CCL) 5, chemokine (C‐X‐C motif) ligand (CXCL) 9, CCL2 and CXCL10 levels were observed in the nasal lavage fluid.ConclusionsThe present findings suggest that Biyeom‐go may be beneficial for the management of rhinitis symptoms and rhinitis‐associated quality of life. Further well‐designed randomised controlled trials are needed to evaluate the effectiveness of Biyeom‐go for rhinitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
