Poor oral health and anorexia in older rehabilitation patients

Association between telomere length and anorexia of ageing: a cross-sectional study conducted with community-dwelling older people

BACKGROUND

To verify whether shorter telomere length is associated with anorexia of ageing in community-dwelling older people.

METHODS

Conducted as a cross-sectional investigation, the study enrolled 448 participants residing in an urban area of a municipality in Brazil. Relative telomere length in blood samples was measured using quantitative polymerase chain reaction (qPCR), whereas the presence of anorexia of ageing was determined using the Simplified Appetite Nutritional Questionnaire. Data analysis employed multiple logistic regression.

RESULTS

Among the 448 older individuals surveyed, 70.69% were female, and the predominant age bracket ranged from 60 to 69 years (45.08%). Approximately 25% exhibited the shortest telomeric length, with a corresponding anorexia of ageing prevalence of 41.16%. Older individuals with diminished telomere lengths displayed an increased likelihood of experiencing anorexia of ageing (odds ratio [OR] = 1.92; 95% confidence interval [CI] = 1.12-3.29), independent of factors such as gender, age group, depressive symptoms, pain and performance in basic daily life activities.

CONCLUSIONS

The observed association between anorexia of ageing and a telomeric biomarker underscores the imperative to meticulously evaluate the nutritional dimensions of older people, with a view to implementing interventions that may enhance their overall health status.

Reliability and validity of Chinese version of the Simplified Nutritional Appetite Questionnaire (SNAQ) in community-dwelling old people

OBJECTIVE

To investigate the reliability and validity of the Chinese version of simplified nutritional appetite questionnaire (SNAQ).

METHODS

The SNAQ was translated and back-translated for the study population. We surveyed 122 community-dwelling residents aged ≥60 years in Beijing's residential communities. Participants underwent face-to-face surveys including the SNAQ, mini-nutritional assessment short-form (MNA-SF), FRAIL scale, Sarcopenia-Five (SCAR-F), 15-item Geriatric Depression Scale (GDS-15), 7-item Generalized Anxiety Disorder (GAD-7), 8-item Oral Frailty Index (OFI-8), 10-item Eating Assessment Tool (EAT-10), and Mini-Mental State Examination (MMSE). Cronbach's alpha was used to measure the internal consistency and the relationship between individual items. The construct validity was verified using the KMO-Bartlett. Concurrent validity was established to validate measures of the same constructs.

RESULTS

Cronbach's alpha measured the internal consistency of the questionnaire at 0.694. The split-half reliability stood at 0.725. The construct validity of the SNAQ was confirmed using a KMO-Bartlett value of 0.648 (P <0.001). The MNA-SF, as validation benchmark, has a correlation coefficient of 0.345 (P =0.001).

CONCLUSION

The Chinese version of the SNAQ has good reliability and validity for older adults in community settings.

Impact of Hospital Dentistry on Patients' Food Intake Status in Convalescent Rehabilitation Ward

BACKGROUND

Treating oral problems with dentist intervention during hospitalisation may improve patients' food intake status.

OBJECTIVES

This study aimed to clarify whether convalescent rehabilitation ward inpatients in a hospital with hospital dentistry (HHD) had a better diet at discharge than those in a hospital without hospital dentistry (HNHD).

METHODS

Retrospective observational study including inpatients with dental involvement in a HHD with dentists and dental hygienists and HNHD with dental hygienist and visiting dental service between 1 March and 31 August 2022. Data included age, sex, body mass index (BMI), Functional Independent Measure (FIM) motor and cognitive, Oral Health Assessment Tool (OHAT) score, Food Intake LEVEL Scale (FILS), whether the FILS ≥8 (indicating that patient eats also a non-texture-modified diet), remained and functional tooth numbers and speech language hearing therapist (SLHT) and dentist interventions. Comparisons between the two hospitals and factors that affected the FILS ≥8 were examined.

RESULTS

A total of 333 and 89 inpatients were included in the HHD and HNHD groups, respectively. After propensity score matching, the HHD group had a significantly higher rate of FILS ≥8, functional tooth numbers at discharge, and SLHT and dentist intervention rates. The multivariable logistic regression analysis for propensity score matching participants showed that the significant independent variables for FILS ≥8 were age, BMI, FILS, FIM motor (all at admission) and SLHT and dentist interventions. Odds ratio for dentist intervention was 14.46 (95% CI: 4.36-48.01).

CONCLUSIONS

Dentists are necessary to improve patients' food intake status in convalescent rehabilitation wards.

Pilot study on the relationship between oral function or subjective symptoms and appetite

OBJECTIVE

This pilot study evaluated the relationships between appetite and oral function, and between appetite and the subjective symptoms of decreased oral function.

METHODS

Seventy-one adult dental clinic patients (22 males, 66.0 ± 14.0 years) participated in this study. A Council on Nutrition Appetite Questionnaire score of ≤28 indicated anorexia, and the Mini Nutritional Assessment Short-form, body mass index and skeletal muscle mass index were used to define subject characteristics. Seven oral function tests and seven subjective symptoms related to oral function were evaluated. The relationship between subject characteristics, oral function tests, subjective symptoms and anorexia was analysed using the chi-square test and univariate and multivariate logistic regression.

RESULT

There were significant differences between the normal appetite group and the anorexia group for the 10-item Eating Assessment Tool (EAT-10) survey and the question 'Food remains in the oral cavity after eating' (p < .05). Univariate logistic regression found significant differences in the items of masticatory function, the EAT-10 survey and the question 'Food remains in the oral cavity after eating'. Multivariate logistic regression revealed significant differences in masticatory function (AOR 4.35; 95% CI: 1.03-18.35; p = .045) and EAT-10 (AOR 6.27; 95% CI: 1.40-24.02; p = .016).

CONCLUSION

This pilot study investigated the influence of factors related to oral function on appetite. Relationships were found among poor masticatory function, poor swallowing function and anorexia.

Developing tongue coating status assessment using image recognition with deep learning

PURPOSE

To build an image recognition network to evaluate tongue coating status.

METHODS

Two image recognition networks were built: one for tongue detection and another for tongue coating classification. Digital tongue photographs were used to develop both networks; images from 251 (178 women, 74.7±6.6 years) and 144 older adults (83 women, 73.8±7.3 years) who volunteered to participate were used for the tongue detection network and coating classification network, respectively. The learning objective of the tongue detection network is to extract a rectangular region that includes the tongue. You-Only-Look-Once (YOLO) v2 was used as the detection network, and transfer learning was performed using ResNet-50. The accuracy was evaluated by calculating the intersection over the union. For tongue coating classification, the rectangular area including the tongue was divided into a grid of 7×7. Five experienced panelists scored the tongue coating in each area using one of five grades, and the tongue coating index (TCI) was calculated. Transfer learning for tongue coating grades was performed using ResNet-18, and the TCI was calculated. Agreement between the panelists and network for the tongue coating grades in each area and TCI was evaluated using the kappa coefficient and intraclass correlation, respectively.

RESULTS

The tongue detection network recognized the tongue with a high intersection over union (0.885±0.081). The tongue coating classification network showed high agreement with tongue coating grades and TCI, with a kappa coefficient of 0.826 and an intraclass correlation coefficient of 0.807, respectively.

CONCLUSIONS

Image recognition enables simple and detailed assessment of tongue coating status.

The association between objective and subjective oral health conditions and the presence of anorexia of aging among Japanese older Adults1

Anorexia of aging is a risk factor for malnutrition among older adults. This study aimed to evaluate the association between objective and subjective oral health and anorexia among independent older adults. This cross-sectional study targeted independent older adults aged ≥65 years who participated in the Japan Gerontological Evaluation Study conducted in 2022. The outcome variable was the presence of anorexia, as assessed by the Simplified Nutritional Appetite Questionnaire. Exposure variables were dental status (≥20 teeth, 10-19 teeth with/without dentures, and 0-9 teeth with/without dentures) as objective oral health and oral health-related quality of life measured by five items of the short version of the Oral Impacts on Daily Performances (OIDP) (eating, speaking, smiling, emotional stability, and enjoying with others) as subjective oral health. We fitted the Poisson regression model, including possible confounders, and estimated prevalence ratios (PRs) and 95% confidence intervals. Among 19,787 participants (mean age: 74.6 years [1SD = 6.2], male: 48.5%), 9.0% were classified as having anorexia. After adjusting possible confounders, those with ≤19 teeth had a higher proportion of experiencing anorexia compared to those with ≥20 teeth; however, the association was less pronounced among those with dentures (0-9 teeth with dentures: PR = 1.48 [1.31-1.68], and 0-9 teeth without dentures: PR = 2.08 [1.65-2.63]). Even after adjusting for dental status, each item of OIDP was significantly associated with the presence of anorexia (all p < 0.05). The results showed that both objective and subjective poor oral health were significantly associated with a higher probability of developing anorexia of aging. Therefore, improving both objective and subjective oral health through appropriate dental care could contribute to maintaining appetite in later life.

Consequences of Anorexia of Aging in Hospital Settings: An Updated Review

The anorexia of aging is a widespread problem amongst older people, particularly in the hospital setting with up to 60% affected. Despite its high prevalence anorexia often goes undiagnosed in hospital, due to a lack of standardized assessment and evidence-based management, but also lack of knowledge regarding consequences. This review summarizes current evidence for anorexia of aging specific to the hospital setting, giving an overview of correlates of appetite in hospital and consequences of anorexia. It highlights an overall scarcity of research on this important clinical problem for hospitalized cohorts. The few studies point to the importance of anorexia of aging in major health burdens for older people, namely malnutrition, sarcopenia and reduced physical performance, as well as higher mortality. Further research is needed to assess temporal sequence in pathways of causality and to develop effective interventions to combat anorexia.

Measures for Identifying Malnutrition in Geriatric Rehabilitation: A Scoping Review

Malnutrition is a common condition in geriatric rehabilitation settings; however, the accuracy and predictive validity of the measures to identify malnutrition have not been established. The current scoping review followed the Joanna Briggs Institute's evidence synthesis manual and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews checklist. Literature published through September 2023 was searched using MEDLINE and CINAHL. The inclusion criteria selected studies reporting malnutrition measures, which include static body weight and weight loss. Identified tools were classified as nutritional screening tools, nutritional assessment tools, or diagnostic criteria. The domains of each tool/criterion and their accuracy and predictive validity were extracted. Fifty-six articles fulfilled the inclusion criteria, and six nutritional screening tools, three nutritional assessment tools, and three diagnostic criteria for malnutrition were identified. These measures consisted of various phenotypes, e.g., weight loss, causes such as inflammation/disease, and risk factors of malnutrition, e.g., functional impairment. The predictive validity of nutritional screening tools (n = 6) and malnutrition diagnostic criteria (n = 5) were inconsistently reported, whereas those for nutritional assessment tools were scarce (n = 1). These findings highlight the need to distinguish the functional impairment of nutritional origin from that of non-nutritional origin in nutritional assessment procedures, and the need to study the accuracy and the predictive validity of these measures in geriatric rehabilitation patients.

Association between oral health status and functional independence measure on admission in convalescent hospitalized patients

BACKGROUND

Oral health management has become increasingly important for acute inpatients. Older patients often require extended periods of medical care, and oral health management is necessary in the convalescent period following the acute period. During the convalescent period, oral health management remains unclear as convalescent hospitals have limited dental resources, and effective dental care must be provided if the objective of hospitalization is to improve life functions. This study aimed to clarify the relationship between daily functioning and oral health status at the time of admission to a convalescent hospital to aid in improving daily functioning in the convalescent period.

METHODS

We included patients admitted to the rehabilitation department of a specific convalescent hospital from January to December 2021. A total of 375 patients were included in the study, with complete data records. At admission, we gathered information from the medical records, including the patient's age, sex, primary disease, Charlson Comorbidity Index, Mini Nutritional Assessment Short-Form (MNA-SF), Functional Oral Intake Scale (FOIS), Functional Independence Measure (FIM), number of teeth, and Oral Health Assessment Tool (OHAT). Statistical analysis was conducted using SPSS Ver. 27, with a significance level of 5%.

RESULTS

The mean age of the 375 participants (189 men and 186 women) was 75.0 ± 12.1 years (range, 42-97 years), and over 80% were > 65 years. About 30% of major diseases could be attributed to strokes and fractures, followed by spinal cord and spine diseases. In non-stroke patients, multiple regression analysis using FIM motor, FIM cognitive, and FIM and OHAT total scores as objective variables showed that higher total scores of MNA-SF, FOIS, and lower modified Rankin Scale and OHAT were significantly associated with better FIMs. Lower OHAT scores were significantly associated with lower FOIS and MNA-SF scores, male sex, having fewer teeth, and poor dietary patterns.

CONCLUSIONS

The convalescent period is an opportune time to provide intensive dental care due to the generally stable condition and extended hospital stay. Our results suggest that oral health management, such as dysphagia rehabilitation and denture treatment, is important for maintaining and improving independence, a key objective of convalescent rehabilitation, and malnutrition improvement.

Factors influencing the selection of oral healthcare providers in multidisciplinary Nutrition Support Team for malnourished inpatients: A cross-sectional study

BACKGROUND

Oral health management involving dental professionals in a multidisciplinary Nutritional Support Team (NST) is effective collaborative care. However, the indicators for the triage of oral health management requirements and selection of oral healthcare providers remain unclear.

OBJECTIVE

This cross-sectional study included inpatients with malnutrition and aimed to investigate the factors associated with determining the need for oral health management involving dental professionals and selecting primary oral healthcare providers when needed.

METHODS

Participants included 255 inpatients (154 males and 101 females, mean age 69.7 ± 14.4 years) aged ≥20 years who underwent oral assessment by the NST between April 2016 and July 2019. Participants were assigned to the following groups: good oral health group, oral health management by nurses under the supervision of dental professionals group, and oral health management by dental professionals group. The comprehensive oral health status was investigated using the Oral Health Assessment Tool (OHAT). The total OHAT score ranges from 0 to 16, with a higher score indicating a poorer oral environment.

RESULTS

The total OHAT score had a significant correlation with the need for oral health management by dental professionals. Inpatients with denture problems required oral health management from dental professionals. The optimal cutoff value of the total OHAT score for determining the need for oral health management was four.

CONCLUSION

The need for oral health management by dental professionals increased with worsening oral health status, especially denture problems. The OHAT score could be used to triage inpatients who require oral health management collaborated with dental professionals.

Impact of Poor Oral Health Status on Swallowing Function Improvement in Older Dysphagic Patients

Background This study aimed to explore the relationship between poor oral health status and improvement in swallowing function in older patients with dysphagia across various clinical settings, including acute and post-acute care environments. Methods This retrospective cohort study encompassed patients aged 65 years and older with dysphagia. Oral health status was assessed using the oral health assessment tool (OHAT) or the revised oral assessment guide (ROAG). In this study, an OHAT score of ≥3 or an ROAG score of ≥13 indicated poor oral health status. The primary outcome measured was the change in the food intake level scale (FILS) score, which reflects swallowing function, during the observation period. The association between changes in FILS score and poor oral health status was analyzed using a multivariable linear regression model. Results The study included 361 older patients with dysphagia (mean age 82.7 ± 7.7 years; 47.3% male), of whom 82.5% had poor oral health. A negative association was found between poor oral health status and improvement in FILS score at the endpoint (partial regression coefficient: -0.523, 95% confidence interval: -0.99 to -0.06, P=0.026). Conclusions Our findings underscore the negative impact of poor oral health status on the improvement of swallowing function and emphasize the importance of oral health interventions for older patients. Further study on oral health interventions' effects on improving swallowing function in older patients with dysphagia is warranted.

A Survey of Oral Assessment and Healthcare Education at Nursing Schools in Japan

OBJECTIVES

This study aimed to investigate the performance of oral assessment and health care education at nursing schools across Japan to identify problems and the need for oral health professional support.

METHODS

The participants were the academic staff in charge of oral health care education in the basic, adult, gerontological, and home nursing fields of 295 schools in Japan that offered a bachelor's degree in nursing. A questionnaire was sent to 1180 heads of the nursing fields of these schools. They were requested to have oral health care educators complete the survey; data on the performance of oral assessment and health care education and human resources allocated were collected through a questionnaire.

RESULTS

A total of 311 (26%) questionnaires were returned, 196 (63%) of which were completed by oral health care educators. Regarding the performance of oral assessment education, the majority (71%) of them spent less than 2 hours in teaching, and only 24.5% taught the usage of oral assessment tools. Regarding the performance of oral health care education, more than 90% spent less than 2 hours in lecture-based and practical oral health care education, respectively. Less than half taught the association of periodontal diseases with diabetes and cardiovascular diseases and use of fluoride for caries prevention in the lectures, and only approximately 30% taught the usage of an interspace brush or dental floss. Moreover, less than 10% of oral health professionals taught oral health care in lectures or practical oral health care.

CONCLUSIONS

This study revealed problems associated with oral assessment and health care education in Japanese nursing schools. To address these, support from oral health care professionals is required. Further studies are also required to reveal problems in oral assessment and health care education in other nursing schools that do not offer a bachelor's degree programme in Japan and other countries.

The Association between Oral Health Management and the Functional Independence Measure Scores at the Time of Admission of Inpatients to a Convalescent Hospital

Many older patients admitted to convalescent hospitals present with impaired oral function, which is an important function of daily life. This study aimed to investigate the actual status of the oral healthcare needs of inpatients in a convalescent hospital and to clarify the relationship between the level of independence at admission and the oral function. The participants were 147 patients (94 males, 53 females, mean age: 74.6 ± 13.1 years) who received dental visits during their stay at a convalescent hospital. Information regarding general and oral health was extracted from medical records. Most patients were found to have low Functional Independence Measure motor scores, and approximately 70% had some form of oral intake, but approximately 80% had nutritional problems. The mean number of present and functional teeth were 16.6 and 20.8, respectively, and 65% of patients lost molar occlusal support. Multiple regression analysis showed significant positive correlations of high functional independence measure with age, eating status, nutritional status, and the number of functional teeth. This implied that oral health management is important for patients in a convalescent hospital and that enhancing oral health may be related to improved eating textures and better nutritional status.

Association of poor oral health status and faecal incontinence in patients with dysphagia: A cross-sectional analysis from the Sarcopenic Dysphagia Database

BACKGROUND

Poor oral health status may alter oral and gut microbiota. Previous studies have shown that poor oral health can exacerbate gut inflammation. Therefore, poor oral health status may be related to faecal incontinence via changes in the gut.

OBJECTIVE

To investigate the association between poor oral health status and faecal incontinence in inpatients with dysphagia.

METHODS

This multicentre cross-sectional study included 423 patients (mean age 79.8 ± 11.5 years, 48.2% female) with dysphagia. Oral health status was assessed at each facility using the Oral Health Assessment Tool (OHAT) or the Revised Oral Assessment Guide (ROAG). Poor oral health status was defined as an OHAT score of ≥3 or a ROAG score of ≥13. A multivariate logistic model was used to analyse the association between poor oral health status and faecal incontinence.

RESULTS

A total of 351 (83.0%) patients had poor oral health and 97 (22.7%) had faecal incontinence. Patients with poor oral health status had a higher proportion of faecal incontinence than those with normal oral health status (25.4% vs. 11.1%, p = .009). A multivariate logistic model revealed an association between faecal incontinence and poor oral health status (adjusted odds ratio = 2.501, 95% confidence interval = 1.065-5.873, p = .035).

CONCLUSIONS

Poor oral health status assessed by OHAT or ROAG in inpatients with dysphagia may adversely affect faecal incontinence. Further studies are needed to determine the causal relationship between poor oral health status and faecal incontinence.

Relationship between oral health and prognosis in patients with empyema: Single center retrospective study with propensity score matching analysis

BACKGROUND

Empyema is a life-threatening infection often caused by oral microbiota. To the best of our knowledge, no reports have investigated the association between the objective assessment of oral health and prognosis in patients with empyema.

MATERIALS AND METHODS

A total of 63 patients with empyema who required hospitalization at a single institution were included in this retrospective study. We compared non-survivors and survivors to assess risk factors for death at three months, including the Renal, age, pus, infection, diet (RAPID) score, and Oral Health Assessment Tool (OHAT) score. Furthermore, to minimize the background bias of the OHAT high-score and low-score groups determined based on the cut-off value, we also analyzed the association between the OHAT score and death at 3 months using the propensity score matching method.

RESULTS

The 3-month mortality rate was 20.6% (13 patients). Multivariate analysis showed that a RAPID score ≥5 points (odds ratio (OR) 8.74) and an OHAT score ≥7 points (OR 13.91) were significantly associated with death at 3 months. In the propensity score analysis, a significant association was found between a high OHAT score (≥7 points) and death at 3 months (P = 0.019).

CONCLUSION

Our results indicated that oral health assessed using the OHAT score may be a potential independent prognostic factor in patients with empyema. Similar to the RAPID score, the OHAT score may become an important indicator for the treatment of empyema.

Changes in Nutrition-Intake Method and Oral Health through a Multidisciplinary Team Approach in Malnourished Older Patients Admitted to an Acute Care Hospital

Malnourished older inpatients referred to a nutrition support team (NST) usually receive multidisciplinary oral health management during NST intervention. However, the effects of multidisciplinary oral health management on the nutrition-intake method and oral health in these patients remain unclear. This longitudinal study aimed to investigate the effects of NST-mediated multidisciplinary oral health management on the nutrition-intake methods, oral health, and the systemic and oral factors influencing the changes in the nutrition-intake method. A total of 117 inpatients (66 men, 51 women, mean age, 71.9 ± 12.5 years) who underwent NST-mediated multidisciplinary oral health management between April 2016 and July 2019 were enrolled. Demographic data and Functional Oral Intake Scale (FOIS), Dysphagia Severity Scale (DSS), and Oral Health Assessment Tool (OHAT) scores at the time of referral to the NST and completion of the NST intervention were evaluated. After multidisciplinary NST intervention, FOIS, DSS, and OHAT scores showed significant improvements (p < 0.001). Even after adjusting the results for systemic parameters, FOIS score improvement correlated positively with the length of NST intervention (p = 0.030) and DSS score improvement (p < 0.001) as well as OHAT score improvement (p = 0.047). NST interventions with multidisciplinary oral health management could improve the nutrition-intake method.
