AimMalnutrition is reportedly associated with the development of delirium. As dental health is essential for nutritional intake, tooth loss may be a risk factor for the development of delirium. This study aimed to investigate the relationship between postoperative delirium and the number of remaining teeth in patients undergoing gastrointestinal surgery.MethodsThis retrospective study included 453 consecutive patients aged ≥65 years who underwent programmed gastrointestinal cancer surgery under general anesthesia at the Department of Surgery, Fujita Health University Hospital, between January 2022 and December 2022. Background factors were prepared between the participants with and without dental intervention. In the dental intervention group, associations between background and surgical factors and the presence of postoperative delirium were explored. Factors with significant associations with postoperative delirium in the univariate analysis were subjected to logistic regression analysis to determine their association with the number of remaining teeth.ResultsOverall, 189 participants underwent postoperative management. They had a significantly lower Prognostic Nutritional Index and higher cognitive decline than the 264 patients who underwent no dental intervention during this period. However, no significant difference was observed in the incidence of postoperative delirium between the two groups. In the dental intervention group, logistic regression analyses revealed that postoperative complications and the number of remaining teeth were significantly associated with postoperative delirium development.ConclusionThe results revealed that a decrease in the number of remaining teeth is associated with postoperative delirium. The cause of this is not clear, but it is thought to be related to brain fragility. Geriatr Gerontol Int 2024; ••: ••–••.

Objectives This study examined the impact of the Center of Healthy Aging Program (CHAP) on the cognitive function and economic burden associated with dementia. Methods This observational study utilised Iwaki cohort data. We included participants with mini-mental state examination (MMSE) scores and categorised them into pre- and post-CHAP groups based on their year of entry into the cohort (before 2013 or after) (index year). We defined participants with suspected severe cognitive impairment and suspected mild cognitive impairment using their MMSE scores, with their incidence being the first observation meeting these definitions during the follow-up period. We compared the incidence rates between the pre- and post-CHAP groups using Cox proportional hazard analysis. Medical and caregiving costs were estimated based on the projected number of residents in Iwaki area with suspected mild cognitive impairment and sSCI during hypothetical 10 years of the CHAP implemented or not and compared. Results Of the 2,569 participants, 1716 and 853 were included in the pre- and post-CHAP groups, respectively. The incidence rate of suspected mild cognitive impairment was significantly lower in the post-CHAP group even after adjusted known factors associated with cognitive disorders. No cases of suspected severe cognitive impairment occurred in the post-CHAP group during the follow-up period. Estimated costs of JPY 1,628,450 (USD 11562.00 or EUR 10259.24, JPY 100 = USD 0.71 or EUR 0.63) and JPY 789,560 (USD 5605.88 or EUR 4974.23) per person per year were projected after 10 years with and without the CHAP, respectively. Conclusions We demonstrated a reduction in the incidence rate of suspected mild cognitive impairment among residents who participated in the CHAP and a decrease in the medical and caregiving costs associated with suspected severe cognitive impairment.
