A prospective cohort study on factors related to dental care and continuation of care for older adults receiving home medical care.

Information on the effects of dental treatment must be identified and factors that hinder the continuation of dental treatment must be identified to provide appropriate domiciliary dental care (DDC). This study aimed to clarify the treatment outcomes of DDC for older adults and the factors that impede the continuation of such care. This prospective study was conducted at a Japanese clinic specializing in dental care for older adults. The functional status, nutritional status, oral assessment, details of the dental treatment, and outcomes after 6 months of older adults receiving DDC were surveyed. The Oral Health Assessment Tool (OHAT) was used for oral assessment. Cox proportional hazards analysis was used to analyze the factors at the first visit that were associated with treatment continuation. A total of 72 participants (mean age, 85.8 ± 6.9) were included. Twenty-three participants (31.9%) could not continue treatment after 6 months. The most frequently performed procedures were oral care and dysphagia rehabilitation, followed by prosthetic treatment, then tooth extraction. The percentage of participants with teeth that required extraction after 6 months and the total OHAT score decreased significantly. The Barthel Index, Mini Nutritional Assessment Short-Form, and rinsing ability were significantly associated with treatment continuation. Furthermore, instrumental activities of daily living (ADL) and the OHAT "tongue" sub-item were correlated with treatment continuation. In conclusion, DDC improved the oral health status of older adults after 6 months. Factors that impeded treatment continuation were decreased ADL, decreased nutritional status, difficulty in rinsing, and changes in the tongue such as tongue coating.

Usefulness of Telemedicine for Disabled Children Receiving Feeding Therapy.

We performed a retrospective cohort study using medical records of 374 pediatric patients who visited a university dental clinic specializing in dysphagia rehabilitation in Japan between 2019 and 2020 to clarify the usefulness of telemedicine among disabled children receiving feeding therapy. The primary outcome was the feeding developmental stage confirmed at the final evaluation. Propensity score matching was performed between individuals in two treatment groups (in-person and telemedicine) before the final analysis using patients' age, sex, primary disease, gross motor function, and feeding developmental stage as covariates. A total of 36 patients were enrolled in each of the in-person and telemedicine groups. The initial evaluation for the propensity score matched population using the χ2 test showed no significant difference between the two groups in any parameter. The feeding developmental stage evaluated at the final evaluation using the Wilcoxon signed-rank test significantly improved compared with the stage at the initial evaluation in both groups (in-parson group, p = 0.007; telemedicine group, p = 0.013). The difference in level achieved at the final evaluation revealed that the most common level was "unchanged," followed by "improvement by one level" in both groups, indicating that there was no significant difference in the efficacy of feeding therapy between the two groups (p = 0.314). Our results show that telemedicine can achieve the same therapeutic outcomes as in-person therapy to improve feeding function in children with disabilities when receiving feeding therapy.

Effect of dysphagia rehabilitation in patients receiving enteral nutrition at home nursing care: A retrospective cohort study.

OBJECTIVE: We considered the effect of dysphagia rehabilitation and investigated parameters associated with the resumption of oral intake in the elderly patients receiving home nursing care who were not eating by mouth. METHODS: The participants were 116 patients aged ≥65 years (66 men and 50 women, mean age 79.7 ± 8.9 years) who were receiving home nursing care and not eating by mouth because of dysphagia. All patients underwent dysphagia rehabilitation for 6 months with the objective of resuming oral intake. After 6 months of dysphagia rehabilitation, the patients' eating status was assessed using the Functional Oral Intake Scale (FOIS) and the associations of the post-intervention FOIS score with age, history of pneumonia, duration of enteral nutrition, body mass index (BMI), alertness, physical function (ability to walk) and swallowing function at the initial examination. RESULTS: Functional Oral Intake Scale scores increased significantly after 6 months rather than those at the initial evaluation (P < .001). Eighty patients (69.0%) resumed oral intake (FOIS score ≥2), thirty patients (25.9%) of whom became capable of daily oral intake (FOIS score ≥3). Swallowing function was associated with the resumption of oral intake. In addition, physical function before dysphagia rehabilitation was an important factor to resume daily oral intake. CONCLUSIONS: The results of the present study suggest that the resumption of oral intake by patients receiving enteral nutrition requires improvement in swallowing function. In addition, anyone who cannot walk may not recover daily oral intake.

Relationship between maintenance of occlusal support achieved by home-visit dental treatment and prognosis in home-care patients-a preliminary study.

AIM: To determine whether occlusal maintenance and reconstruction by dental intervention is associated with the prognosis of older home-care patients. METHODS: The study participants were 289 older home-care patients (101 males, mean age 82.2 ± 7.7 years) who received visiting dental treatment from dental clinics in the region between 2012 and 2018. The participants were followed up for 1000 days after receiving the necessary dental treatment in a home-visit setting. The participants were divided into three groups: those with natural tooth occlusion, those whose molar occlusion was maintained or reconstructed by dentures, and those whose occlusion was not reconstructed. Factors associated with prognosis were determined using the Cox proportional hazard model, with occlusal status, comorbidities, the activity of daily living, and residence status as explanatory variables. RESULTS: In the overall population, occlusal status (hazard ratio [HR] of those with occlusal disintegration versus those with natural tooth occlusion: 2.1, confidence interval [95% CI]: 1.18-3.82) and age (HR: 2.28, 95% CI: 1.44-3.61) were identified as significant factors. In the group of participants aged <85 years, only occlusal status (HR of those with occlusal disintegration versus those with natural tooth occlusion: 3.4, 95% CI: 1.34-8.68) was a significant factor. In the group of participants aged ≥85 years, occlusal status was not significantly associated with prognosis. CONCLUSIONS: The maintenance and acquisition of occlusal support achieved by dental treatment contribute to improved prognosis in older patients younger than 85 years requiring home nursing care.

Tongue function is important for masticatory performance in the healthy elderly: a cross-sectional survey of community-dwelling elderly.

PURPOSE: The aim of this study was to determine the influences of oral motor function such as tongue function and bite force on masticatory performance in the elderly. METHODS: We randomly selected 245 subjects who has 28 natural teeth among community-dwelling elderly. We evaluated masticatory performance using a gummy jelly, and also measured bite force, tongue muscle force, and the speed of tongue movement. RESULTS: We found that reduced masticatory performance to be associated with decreased the speed of tongue movement and/or tongue muscle force, indicating that reduced oral motor function also influences masticatory performance. CONCLUSIONS: These results suggest that keeping oral motor function, as well as maintenance of occlusal support, to be important for maintaining masticatory function in the elderly.

Oral Frailty as a Risk Factor for Physical Frailty and Mortality in Community-Dwelling Elderly.

Background: Oral health is important for maintaining general health among the elderly. However, a longitudinal association between poor oral health and general health has not been reported. We investigated whether poor oral status can predict physical weakening (physical frailty, sarcopenia, and subsequent disability) and identified the longitudinal impact of the accumulated poor oral health (i.e. oral frailty) on adverse health outcomes, including mortality. Methods: A total of 2,011 elderly individuals (aged ≥ 65 years) participated in the baseline survey of the Kashiwa study in 2012. At baseline, 16 oral status measures and covariates such as demographic characteristics were assessed. As outcomes, physical frailty and sarcopenia were assessed at baseline and at follow-up in 2013 and 2014. Physical independence and survival were assessed from 2012 to 2016 at the time of long-term care certification and time of death. Results: Poor oral status as determined by the number of natural teeth, chewing ability, articulatory oral motor skill, tongue pressure, and subjective difficulties in eating and swallowing significantly predicted future physical weakening (new onsets of physical frailty, sarcopenia, and disability). Oral frailty was defined as co-existing poor status in ≥3 of the six measures. Sixteen per cent of participants had oral frailty at baseline, which was significantly associated with 2.4-, 2.2-, 2.3-, and 2.2-fold increased risk of physical frailty, sarcopenia, disability, and mortality, respectively. Conclusion: Accumulated poor oral status strongly predicted the onset of adverse health outcomes, including mortality among the community-dwelling elderly. Prevention of oral frailty at an earlier stage is essential for healthy aging.

Eating Alone as Social Disengagement is Strongly Associated With Depressive Symptoms in Japanese Community-Dwelling Older Adults.

OBJECTIVES: Depression in later life poses a grave challenge for the aging countries. The reported key risk factors include social disengagement, but the lack of social companionship during mealtimes, namely eating alone, has not been examined extensively, especially in relation to living arrangement. Past studies on changes along geriatric trajectories in the association between social engagement and depression also remain inadequate. This study aims to examine the association between social engagement and depressive symptoms with a particular focus on eating alone and how the association changes along the aging and mental frailty trajectories. DESIGN: A cross-sectional study. SETTING: Kashiwa-city, Chiba-prefecture in Japan. PARTICIPANTS: A total of 1856 community-dwelling older adults. MEASUREMENTS: The 15-item Geriatric Depression Scale was used to measure depressive symptoms. The indicators used to assess social engagement included eating alone, living arrangement, reciprocity of social support, social participation, social stressors and social ties. RESULTS: Social engagement was significantly associated with depressive symptoms. Those who live with their families yet eat alone were found to be at particular risk (odds ratio = 5.02, 95% confidence interval 2.5-9.9 for young-old; odds ratio = 2.41, 95% confidence interval 1.2-4.8 for old-old). Younger and less mentally frail populations showed stronger associations. CONCLUSIONS: Eating alone was a key risk factor for depressive symptoms in community-dwelling older adults. The living arrangement in which they eat alone is important in identifying those with the greatest risk. Mental health management for older adults requires comprehensive assessment of their social relations that takes into account their companionship during mealtimes. Social preventive measures need to involve early interventions in order to augment their effectiveness against mental frailty.
