Poor Oral Health as a Determinant of Malnutrition and Sarcopenia

Quantitative analysis of masseter muscle by ultrasonography according to different occlusion types using Eichner classification in Turkish subpopulation

BACKGROUND

The aim of this study is to investigate the effects of different occlusion types based on the Eichner classification index on the quantitative features of the masseter muscle by using USG and to evaluate whether these features differ according to age and gender in Turkish subpopulation.

METHODS

The thickness and elasticity values of the masseter muscle were performed. Images were acquired bilaterally in the resting position and maximum intercuspidation. The significance level was set as p = 0.05.

RESULTS

Measurements of 120 people showed that the thickness of the right masseter muscle was lower in women compared to men, both when relaxed and when contracted. The thickness of the left masseter muscle was also lower in women when it was contracted. This difference is significant (P < 0.01). The thickness of the right and left masseter muscles at rest in individuals aged 55 and over was significantly less than those in the 18-35 age range (P < 0.01). The thicknesses of the right and left masseter muscles at rest were lower in individuals in the Eichner C3 category, while in the contracted state, they were lower in individuals in the B3 and B4 categories.

CONCLUSION

Clinicians should consider these variations in demographic and dental status when designing dental and orthodontic interventions. Taking these factors into account can improve chewing ability and customize treatments better, which may lead to better results for patients of different backgrounds.

Association of 25-hydroxyvitamin D and physical activity with oral care needs among older U.S. adults

OBJECTIVES

This study aimed to investigate the independent and combined association of serum 25-hydroxyvitamin D [25(OH)D] levels and physical activity on oral care needs in older United States (US) adults.

METHODS

A cross-sectional study involving 6509 older adults aged 60 years and above data were included from the 2009-2018 National Health and Nutrition Examination Survey (NHANES). The main data for our study came from Questionnaires Data and Laboratory Data. Oral care needs refer to the different levels of overall care recommendations given by trained interviewers after oral examination of interviewees in the NHANES. The weighted multivariate logistic regression model and restricted cubic spline (RCS) were used to explore the associations between 25(OH)D levels, physical activity, and oral care needs. Additional propensity score matching (PSM) was performed to test the stability and reliability of the results.

RESULTS

The results showed that high serum 25(OH)D levels (OR = 0.99, 95% CI, 0.97-1.00, P = 0.04), and vigorous recreational activity (OR = 0.70, 95% CI, 0.53-0.93, P = 0.01) were independently associated significantly with lower risks of oral care needs. High levels of 25(OH)D combined with adequate physical activity might reduce oral care needs in older adults. The mediation effect analysis also showed a mediating effect of 25(OH)D in the association of vigorous recreational activity and oral care needs.

CONCLUSION

High serum 25(OH)D levels and vigorous recreational activity have been linked to a reduced risk of oral care need among older adults. 25(OH)D is a potential mediator of the reduced need for oral health care associated with vigorous recreational activity when combined effects are considered. Vitamin D supplementation and increased physical activity may be a potential cost-effective oral public health strategy for older adults.

Development of a visualized risk prediction system for sarcopenia in older adults using machine learning: a cohort study based on CHARLS

Introduction

The older adult are at high risk of sarcopenia, making early identification and scientific intervention crucial for healthy aging.

Methods

This study utilized data from the China Health and Retirement Longitudinal Study (CHARLS), including a cohort of 2,717 middle-aged and older adult participants. Ten machine learning algorithms, such as CatBoost, XGBoost, and NGBoost, were used to construct predictive models.

Results

Among these algorithms, the XGBoost model performed the best, with an ROC-AUC of 0.7, and was selected as the final predictive model for sarcopenia risk. SHAP technology was used to visualize the prediction results, enhancing the interpretability of the model, and the system was built on a web platform.

Discussion

The system provides the probability of sarcopenia onset within 4 years based on input variables and identifies critical influencing factors. This facilitates understanding and use by medical professionals. The system supports early identification and scientific intervention for sarcopenia in the older adult, offering significant clinical value and application potential.

Impaired oral status is associated with sarcopenic obesity in post-stroke patients

PURPOSE

Oral problems and muscle health are indeed significant concerns in ageing populations. However, there is limited evidence concerning the association between these issues. The study's focus was to investigate the association between oral problems and sarcopenic obesity, wherein sarcopenia and obesity coexist concurrently, in post-stroke patients.

METHODS

This retrospective, observational, cross-sectional study included patients hospitalised for post-stroke rehabilitation. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. Multiple linear regression analysis was used to examine the association between the ROAG and sarcopenic obesity after adjusting for confounding factors.

RESULTS

A total of 760 patients were included, with a mean (SD) age of 71 (9) years, of whom 408 (54.7%) were male. The median (interquartile range, 25th and 75th percentiles) ROAG was 11 [9, 13]. Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. Multivariate linear analysis showed that ROAG was significantly and positively associated with sarcopenic obesity (β = .091, P = .023), followed by obesity alone (β = .084, P = .044), and sarcopenia alone (β = .081, P = .037).

CONCLUSION

Oral problems were associated with sarcopenic obesity in post-stroke. Oral assessment and intervention may have a positive impact on ADL and QOL in post-stroke patients with sarcopenic obesity.

Association between oral health and physio-cognitive decline syndrome of older adults in China and its sex differences: a cross-sectional study

BACKGROUND

Physio-Cognitive Decline Syndrome (PCDs) is characterized by the coexistence of MIND (mobility impairment, no disability) and CIND (cognitive impairment, no dementia), which predicts dementia risk. Deteriorating oral health can contribute to malnutrition, cognitive decline, and physical frailty, all of which may exacerbate PCDs symptoms. This study investigates the association between oral health and PCDs, exploring sex differences in this relationship.

METHOD

A cross-sectional analysis of the baseline data from the Nanjing Brain Health Cohort included 252 participants aged 60 and older, assessing physical mobility (6-meter walk test, grip strength), cognitive function (MoCA), and oral health (natural teeth count, denture use, tongue and lip motor function, masticatory and swallowing ability, Oral Frailty Index). Logistic regression models were used to examine associations between oral health and PCDs.

RESULTS

Among participants, 15.5% were classified as having PCDs. The odds of having PCDs were lower with a higher number of teeth (OR = 0.939, 95% CI: 0.890-0.991, p = 0.021), while impaired tongue and lip motor function increased the odds of PCDs (OR = 3.811, 95% CI: 1.059-13.717, p = 0.041). In females, the odds of MIND and CIND were lower with a greater number of teeth and denture use. For males, the odds of PCDs were higher with oral frailty (OR = 5.202, 95% CI: 1.429-18.940, p = 0.012).

CONCLUSIONS

Findings underscore the significant association between oral health and the odds of PCDs among older adults, with sex-specific effects. For women, maintaining natural teeth and proper denture use are associated with lower odds of MIND and CIND, while for men, oral frailty is linked to higher odds of PCDs. Healthcare providers should consider oral health and incorporate sex-specific strategies.

Comparative in vitro study of a new silicone mouth swab for soft tissue cleaning under wet and dry brushing conditions

The use of silicone mouth swabs for soft tissue cleaning in elderly care is significant as it offers a gentle yet effective solution for maintaining oral hygiene, particularly in patients with limited dexterity or cognitive impairments, thereby reducing the risk of oral infections and improving overall health. This study aimed to compare the pseudo-plaque cleaning efficiency of a newly designed silicone mouth swab with that of the existing MouthEze (MC3) under both wet and dry brushing conditions. A new silicone mouth swab was designed with both straight and threaded brushing bristles and a longer head length of 24.0 mm, compared to the MC3, which has only straight bristles and an 18.0 mm head. A pseudo-plaque, created by mixing 6.0 g of Thicken Up Clear food additive with 12.0 ml of water and food coloring, was spread onto a NISSIN dentoform silicone rubber sheet with a thickness of 2.0 mm. The MC3 silicone head (n = 12) and the new silicone head (n = 12) were attached to a V.P.2000 tooth brushing machine, operating at 75 rounds per minute with a force of 2.45 N, and each was used to brush the surface 25 times under both wet (n = 12) and dry (n = 12) conditions. The ImageJ program was used to analyze and quantify the area where the pseudo-plaque was removed after brushing. A two-way analysis of variance (ANOVA) was conducted to assess differences in pseudo-plaque removal between groups. The pseudo-plaque removal per head length of the new silicone mouth swab was significantly higher than that of the MC3 under both wet brushing (72.30 ± 10.21 mm2 vs. 53.69 ± 5.66 mm2, p < 0.05) and dry brushing conditions (66.82 ± 11.29 mm² vs. 53.33 ± 8.54 mm2, p < 0.05). The new silicone mouth swab with both straight and threaded brushing bristles and a longer head length was more effective in pseudo-plaque removal than the swab with only straight bristles and a shorter head.

Empowering access: unveiling an overall composite spatial accessibility index to healthcare services in Southeastern Iran

BACKGROUND

Access to healthcare is critical for population health; however, geographic barriers persist especially in rural and deprived regions. This study aims to develop an overall composite potential spatial accessibility index to healthcare facilities and services in Sistan and Baluchestan Province in southeast Iran.

METHODS

This study employed the enhanced two-step floating catchment area (E2SFCA) method to create an overall composite spatial accessibility index for healthcare facilities and services in Sistan and Baluchestan Province, southeast Iran. Spatial accessibility for general practitioners, nursing, dentistry, midwifery, pharmacy, medical laboratory, nutrition, public health, radiology, psychology, environmental health, rural health workers, inpatient hospital beds, and five medical specialty services were calculated. Spatial accessibility scores were normalized from 0 to 1 (no access = 0, low = 0.01 to 0.33, moderate = 0.331 to 0.66, high = 0.661 to 1) and aggregated into overall indices of primary, secondary, and overall healthcare accessibility for each district. Inequality was assessed using the Lorenz curve and Gini coefficient analysis.

RESULTS

Low geographic accessibility was found across Sistan and Baluchestan Province, especially in rural areas. Almost 75% of the population had low/no access to overall primary care services within a 30-minute drive time. For secondary care, nearly 45% had low/no access to hospital inpatient beds within a 30-minute drive time, and around 40% had low/no access to specialists within a 60-minute drive time. Just 11.6% of the population had high overall healthcare access. The calculated Gini coefficient of 0.517 for the overall spatial accessibility index to healthcare services in Sistan and Baluchestan Province highlights a highly unequal distribution of healthcare services.

CONCLUSIONS

This study demonstrates a useful replicable methodology that combines individual service accessibility metrics into an overall spatial healthcare access index. Furthermore, this study provides evidence of major shortfalls in healthcare access across Sistan and Baluchestan Province. Targeted strategies are required to increase the availability and capacity of services in underserved communities. Improving geographic access is key for progressing towards universal coverage and better population health.

The Association Between Cognitive Function and Oral Health in Home Dwellers and Nursing Home Residents: The HUNT Study

OBJECTIVES

To evaluate the relationships of cognitive function and care dependency with oral health in a Norwegian older adult population.

METHODS

This cross-sectional study included 2623 participants aged 70 and older from the fourth wave of the Trøndelag health study (HUNT4 70+) and the city of Trondheim (Trondheim 70+). Neurocognitive disorders (NCDs) were diagnosed by clinical experts according to the DSM-5 framework. Care dependency referred to nursing home residency. Oral health was assessed by using the Revised Oral Assessment Guide-Jönköping (ROAG-J). Individuals were considered as 'having oral problem' if the score was two or three in at least one of the nine ROAG-J items. Poisson regression was used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs).

RESULTS

The prevalence of having oral problems was 19% higher in participants with NCDs than those with normal cognitive function after adjusting for potential confounders (PR 1.19, 95% CI: 1.09-1.29). Further analysis showed a higher prevalence of having oral problems for home dwellers with NCDs (PR 1.23, 95% CI: 1.13-1.33) and nursing home residents (PR 1.32, 95% CI: 1.20-1.45) compared to home dwellers with normal cognitive function.

CONCLUSIONS

NCDs were associated with an increased prevalence of oral problems in this Norwegian older adult population. The study suggests the need for increasing oral care for home dwellers with NCDs and nursing home residents.

Practice and challenge of age-friendly functional restoration of stomatognathic system based on the strategy of functional tooth loss

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.

Preventive measures and perceived challenges in delivering oral health care for elderly patients: a survey of dental hygienists in Norway

OBJECTIVE

This study aimed to gain knowledge of general oral health preventive measures with a specific focus on root caries preventive measures for patients ≥65 years old, performed by Norwegian dental hygienists in public and private dental health services. A secondary aim was to investigate differences and challenges in prevention practices.  Materials and methods: An electronic survey was conducted among the sample in 2022. A total of 365 dental hygienists were included in the analyses. Chi-square tests were used to analyze differences between private and public dental hygienists regarding preventive measures and perceived challenges.  Results: The most frequently reported general oral health preventive measures were oral hygiene instruction, professional tooth cleaning and scaling. Oral hygiene instruction and application of fluoride varnish were the most performed root caries preventive measure, and reduced manual dexterity in patients was the most perceived challenge. Public dental hygienists perceived challenges to a greater extent than private dental hygienists, particularly related to reduced mobility and ergonomic difficulties in patients.  Conclusion: This study confirms dental hygienists' important role in oral health promotion and showed that Norwegian dental hygienists performed a wide range of preventive measures for patients ≥65 years old. However, a number of challenges were identified in the preventive work.

Dental Functional Status as a Possible Risk Factor of Sarcopenia: A Computed Tomography-Based Study

BACKGROUND

Functional dentition may be associated with sarcopenia by affecting chewing activity.

OBJECTIVES

The objective of this study is to determine the sarcopenia status of participants using computed tomography (CT)-based data and to investigate the association of sarcopenia with functional dentition, as well as denture condition.

METHODS

The study included 309 patients. The number of teeth was recorded. Functional dentition was evaluated based on the following parameters: (1) ≥ 1 tooth in the maxilla and mandible; (2) ≥ 10 teeth in each arch; (3) the presence of 12 anterior teeth; (4) 3-4 premolar posterior occlusal pairs (POPs) and (5) ≥ 1 molar POP bilaterally. The denture condition was also evaluated. CT-based assessment of sarcopenia was performed via measurement of the psoas muscle area at the level of the L3 vertebra and its hounsfield unit (HU) radiodensity on non-contrast-enhanced images. HU average calculation (HUAC), which is an imaging marker of sarcopenia, was performed. Gender-specific quartiles were then generated, and the lowest quartile of HUAC scores within each gender group was set as the cut-off point.

RESULTS

A total of 76 (24.5%) of the patients had sarcopenia, and 233 (75.5%) did not have sarcopenia. The mean number of teeth in the sarcopenia group was 17.12 ± 8.39, compared to 22.24 ± 6.72 in those without sarcopenia (p < 0.001). The relationship between functional dentition and sarcopenia was also significant. There was a positive relationship between ill-fitting dentures and sarcopenia (p < 0.001).

CONCLUSIONS

This unique perspective of the study contributes to the existing knowledge regarding the role of tooth loss in sarcopenia, highlighting the importance of functional occlusion.

Dietary Counseling: An Option to Malnutrition and Masticatory Deficiency in Patients with Total Protheses? A Scoping Review

Given the rising global population of older adults and their association with edentulism and the use of complete removable prostheses [CRP], it is imperative to pursue solutions for issues such as the relationship between poor diets and masticatory deficiency.

OBJECTIVE

To examine the research on the efficacy of dietary counseling in enhancing mastication and nutrition in older adults with CRP.

METHODS

A systematic literature review was performed in the PubMed, Trip, and Web of Science databases.

RESULTS

812 results were retrieved from the databases, from which 6 clinical studies that fulfilled the qualifying criteria were selected. The selected studies reported reduced nutrition in patients with CRP due to impaired masticatory function. Research suggests that employing basic dietary guidelines or simplified nutritional recommendations enhances the masticatory function of patients with CRP, thereby ensuring sufficient nutritional intake.

CONCLUSION

Dietary counseling improves nutritional intake and masticatory function in patients with CRP. This would allow simple dietary advice to be given to patients with total prostheses in clinical practice. Further randomized clinical trials are recommended to increase the available evidence.

Dentition and weight status in community-dwelling older adults

BACKGROUND/OBJECTIVE

Tooth loss is common among older adults and can affect dietary intake and weight status. This study investigated associations between dentition status and body mass index (BMI) in older adults.

MATERIALS AND METHODS

This was a cross-sectional study of data from a convenience sample of older adults (65-89 years) treated at an urban U.S. dental school clinic. Clinical and demographic data were obtained from electronic health records. Dentition status was determined based on data from odontograms. Multinomial logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of having a non-normal weight status for each measure of dentition status, after adjusting for covariates.

RESULTS

Patients (n = 1765) were 54.1% female, 51.5% White, 41.6% African American and 22.5% Hispanic/Latino. The median (interquartile range [IQR]) age was 71 (67.0-75.0) years; the mean (±SD) BMI was 28.5 (±5.7) kg/m2; 72.5% were overweight or obese. The median (IQR) number of remaining teeth was 20.0 (13.0-24.0); the median numbers of anterior and posterior occluding pairs of teeth were 5.0 (2.0-6.0) and 2.0 (0.0-5.0), respectively; and 44.9% had a functional dentition (≥21 teeth). Having a higher number of remaining teeth and more posterior occluding pairs were associated with lower odds of obesity (OR = 0.980, 95% CI = 0.964, 0.997, p = .022 and OR = 0.931, 95% CI = 0.885, 0.980, p = .006, respectively). Lack of a functional dentition was associated with higher odds of obesity (OR = 1.400, 95% CI = 1.078, 1.818, p = .012), after controlling for covariates.

CONCLUSION

Older adults with tooth loss - especially loss of posterior occlusion and lack of a functional dentition - were more likely to be obese than of normal weight.

Unfavourable Outcomes in Older Adults with Oral Frailty: A Scoping Review

BACKGROUND

The significant occurrence of oral frailty (OF) in older patients highlights the necessity of addressing this concern. OF is associated with complications and mortality in elderly patients. The objective of this study is to identify unfavorable outcomes in older patients with OF to increase awareness and mitigate risks.

METHODS

This review employed specific MeSH terms to perform an extensive literature search on OF and its unfavorable outcomes across PubMed, Web of Science, Embase, Cochrane Library, Scopus, and CINAHL databases. The review included English-language papers published from inception to March 31, 2024, focusing on individuals aged 60 and above, adverse outcomes related to OF, and studies employing cross-sectional or cohort designs.

RESULTS

The review comprised 28 articles: 20 cross-sectional and 8 prospective cohort studies. Among these articles, 10 were rated as "Good" and 18 as "Fair", reflecting the high quality of the literature. Next, 20 OF assessment tools were summarized, and the most frequently used methods for assessing OF were the methods of Tanaka et al and Oral Frailty Index-8 (OF-8). The most frequently unfavorable outcomes related to OF in the elderly were physical frailty, malnutrition, low dietary variety, social withdrawal, disability, and low gait speed.

CONCLUSION

High levels of OF significantly increase the risk of adverse outcomes in older adults, including physical frailty, malnutrition, low dietary variety, social withdrawal, disability, and low gait speed. Effective risk stratification and management are essential to reduce these outcomes.

Impaired oral health associations with cognitive and motor decline in activities of daily living independence during hospitalization: insights from a post-stroke cohort

PURPOSE

Evidence is scarce on the associations between impaired oral health and cognitive level related to independence in activities of daily living (ADLs) among hospitalized older patients. We aimed to evaluate the associations between baseline oral problems and changes in cognitive level in post-stroke patients.

METHODS

A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Revised Oral Assessment Guide (ROAG) as a measure of oral health and function was assessed at admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the motor domain of FIM (FIM-motor). Multivariate linear regression analyses were employed to assess the association between baseline ROAG and the designated outcomes, adjusting for potential confounding factors.

RESULTS

Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median ROAG was 10 [9, 12], with 811 patients (84.9%) presenting oral problems. After fully adjusting for confounding factors, the ROAG was significantly and negatively associated with FIM-cognition at discharge (β = -0.107, p = 0.031) and FIM-cognition gain (β = -0.093, p = 0.018). Further, the ROAG was independently and negatively associated with FIM-motor at discharge (β = -0.043, p = 0.013) and FIM-motor gain (β = -0.065, p = 0.013).

CONCLUSION

Oral problems were associated with compromised cognitive levels and a decline in physical function during the hospitalization in post-stroke patients. These results underscore the critical importance of addressing oral health in this patient population.

Exploring the association of self-rated oral health with self-rated general and mental health among older adults in a resource-poor context: Insights for advancing Sustainable Development Goal 3

INTRODUCTION

Older adults in Ghana have been disproportionately affected by oral health issues such as caries and periodontitis. This situation calls for comprehensive attention within health and healthcare policies, due to the established connections between oral health and other aspects of health and well-being in high-income countries, including physical and mental health. However, there is a significant gap in the literature when it comes to exploring the association of oral health with physical and mental health in resource-constrained settings like Ghana.

METHODS

To address this void, we collected a cross-sectional sample comprising older adults aged 60 and above (n = 1073) and analyzed self-rated health measures to investigate the relationship between oral health and general and mental health in Ghana.

RESULTS

The results of our logistic regression analysis revealed a significant association: older adults who reported poor oral health were more likely to rate their general (OR = 5.10; p < .001) and mental health (OR = 4.78, p < .001) as poor, compared to those with good oral health, even after accounting for demographic and socioeconomic variables.

CONCLUSIONS

Based on these findings, we discuss the policy implications of our findings, especially in the context of advancing Sustainable Development Goal 3 in Ghana and other resource-constrained settings.

Acute Sarcopenia: Mechanisms and Management

BACKGROUND

Acute sarcopenia refers to the swift decline in muscle function and mass following acute events such as illness, surgery, trauma, or burns that presents significant challenges in hospitalized older adults.

METHODS

narrative review to describe the mechanisms and management of acute sarcopenia.

RESULTS

The prevalence of acute sarcopenia ranges from 28% to 69%, likely underdiagnosed due to the absence of muscle mass and function assessments in most clinical settings. Systemic inflammation, immune-endocrine dysregulation, and anabolic resistance are identified as key pathophysiological factors. Interventions include early mobilization, resistance exercise, neuromuscular electrical stimulation, and nutritional strategies such as protein supplementation, leucine, β-hydroxy-β-methyl-butyrate, omega-3 fatty acids, and creatine monohydrate. Pharmaceuticals show variable efficacy.

CONCLUSIONS

Future research should prioritize serial monitoring of muscle parameters, identification of predictive biomarkers, and the involvement of multidisciplinary teams from hospital admission to address sarcopenia. Early and targeted interventions are crucial to improve outcomes and prevent long-term disability associated with acute sarcopenia.

Coexistence of low body mass index and poor oral health negatively affects activities of daily living, swallowing, and cognition after stroke

AIM

Low body mass index (BMI) and poor oral health are prevalent among older stroke patients and associated with adverse outcomes. However, their combined impact on functional recovery after stroke remains unclear. This study investigated the synergistic effects of low BMI and poor oral health on activities of daily living (ADL) independence, swallowing function, and cognitive status in post-stroke older patients.

METHODS

A retrospective cohort study was conducted on 708 hospitalized post-stroke patients aged ≥70 years. Low BMI was defined as <20 kg/m2, and poor oral health was assessed using the Revised Oral Assessment Guide (ROAG) with a score ≥13 indicating oral problems. The primary outcome was ADL independence (Functional Independence Measure-motor score >78) at discharge. Secondary outcomes included swallowing level (Food Intake Level Scale) and cognitive status (Functional Independence Measure-cognition score). Multiple regression analyses were performed to examine the associations of low BMI, poor oral health, and their combination with outcomes of interest.

RESULTS

The coexistence of low BMI and poor oral health was independently associated with lower odds of achieving ADL independence (odds ratio 0.130, 95% confidence interval [CI] 0.023-0.718), worse swallowing level (B = -0.878, 95% CI -1.280 to -0.476), and poorer cognitive status (B = -1.872, 95% CI -2.960 to -0.784) at discharge, after adjusting for confounders. The combined impact was stronger than either condition alone.

CONCLUSIONS

The coexistence of low BMI and poor oral health exerts a synergistic negative impact on functional recovery in older stroke inpatients. Comprehensive interventions integrating nutritional support, oral management, and rehabilitation are crucial to optimizing outcomes in this vulnerable population.

Association Between BMI Reduction and Activities of Daily Living Improvement in Elderly Patients With Musculoskeletal Disorders in a Convalescent Rehabilitation Ward

Background As populations age, musculoskeletal disorders significantly affect the quality of life (QOL) and functional independence of elderly individuals. While BMI is commonly used to assess nutritional status and is linked to physical function, the relationship between BMI reduction and improvements in activities of daily living (ADL) remains unclear in elderly patients with musculoskeletal disorders. This study aimed to explore this relationship in a rehabilitation setting. Methods This retrospective cohort study included 75 elderly patients (65 years and older) with musculoskeletal disorders admitted to a convalescent rehabilitation ward. Patients were categorized into two groups based on BMI reduction: those with a decrease of ≥0.7 kg/m² and those with <0.7 kg/m². Functional Independence Measure (FIM) scores were recorded at admission and discharge. Statistical analyses, including logistic regression, were conducted to examine the relationship between BMI reduction and FIM improvement. Results There was no significant difference in FIM gain between the BMI-reduced and non-BMI-reduced groups. Logistic regression analysis also found no significant association between BMI reduction and FIM improvement, even after adjusting for age, gender, length of stay, and initial FIM scores. Discussion The absence of a significant association may be due to factors such as postoperative swelling, comorbidities, and the predominance of female participants, who may experience less muscle mass loss. Study limitations include the lack of data on dietary intake and body composition. Future research should include broader assessments, such as muscle mass and swelling, to better evaluate rehabilitation outcomes in elderly patients with musculoskeletal disorders.

Dual burden of sarcopenia and impaired oral status on activities of daily living, cognition and swallowing outcomes in post-stroke patients

BACKGROUND AND AIMS

Sarcopenia and poor oral health are common in older patients and are associated with negative outcomes. However, evidence of their combined impact on post-stroke rehabilitation outcomes is limited. This study aimed to investigate the combined impact of sarcopenia and impaired oral health on activities of daily living (ADL), cognition, and swallowing outcomes in post-stroke patients.

METHODS

A retrospective cohort study was conducted using 1,012 post-stroke patients (median age 75.6 years; 54.1 % men). Sarcopenia was diagnosed using the Asian Working Group for Sarcopenia 2019 criteria. Poor oral health was assessed using the Revised Oral Assessment Guide (ROAG) with a score ≥13 indicating impaired oral status. Functional outcomes were measured using the Functional Independence Measure (FIM) for ADL and cognition, and the Food Intake Level Scale (FILS) for swallowing status.

RESULTS

The prevalence of sarcopenia was 45.6 % (492/1,080), impaired oral health was 27.5 % (297/1,080), and the coexistence of both conditions was 12.0 % (130/1,080). The coexistence of sarcopenia and impaired oral health was associated with poorer outcomes compared to either condition alone. After adjusting for confounders, the combination of sarcopenia and impaired oral status showed the strongest negative impact on FIM-motor (B=-8.666, 95 % CI -11.484 to -5.847), FIM-cognition (B=-1.122, 95 % CI -1.987 to -0.256), and FILS (B=-0.785, 95 % CI -1.055 to -0.514) scores at discharge.

CONCLUSION

The dual burden of sarcopenia and impaired oral health significantly impacts functional recovery in post-stroke patients. Comprehensive assessments and interventions targeting both conditions may optimize rehabilitation outcomes in this population.

Digital denture scanning and 3D printing for residents in care homes: A feasibility study for pre-empting denture loss

OBJECTIVE

The aim of this study was to assess the feasibility of digitally scanning dentures and 3D printing replica dentures for care home residents. The study also investigated whether the process and replacement denture was acceptable to the resident.

BACKGROUND

Denture loss is a significant issue for people living in care homes and impacts on nutrition, quality of life and dignity. Denture loss is underreported, and care home residents have barriers to accessing dental care. The conventional process for remaking a denture can often take approximately 2 months with multiple clinical stages, often not feasible in adults with frailty and cognitive impairment. Scanning and 3D (3 dimensional) printing are increasingly used in dentistry, this rapidly evolving technology may provide an innovative solution to denture loss.

MATERIALS AND METHODS

A digital workflow was established using a handheld scanner and 3D printing technology. Care home residents wearing functional acrylic dentures were recruited. Dentures were scanned within the care home, and the scan was sent to a dental laboratory for 3D printing. The dentures were fitted at a subsequent visit, and semi-structured interviews were undertaken with the resident. Using thematic analysis, the feasibility of this pathway was assessed, and the use of digital scanning technology was explored.

RESULTS

Eight residents successfully had dentures scanned and replicated to a satisfactory standard. It took, on average, 10 minutes to scan a denture and 20 minutes to print the denture. All replica dentures were satisfactory to the resident. Qualitative data from semi-structured interviews showed that study participants were satisfied with denture replacements and the process. The 3 main themes that emerged were: the significance of dentures to the individual, satisfaction with the scanning process and general low self-esteem and fatigue.

CONCLUSIONS

This study has established a workflow for digitally storing dentures and replicating them satisfactorily. In the context of a care home setting, a scan of a denture can be used to provide a replacement denture if lost or broken. A large-scale study could follow now that the feasibility of this pathway has been demonstrated.

Perception of Caregivers about Oral Health Services for Institutionalized Older Adults: A Mixed Method Study

BACKGROUND

In India, the absence of formal training in geriatric dentistry and the lack of recognition of it as a speciality contributes to the deterioration of oral health in the older adults. India lacks specific oral healthcare policies for older adults. Additionally, caregivers' perspective in old age homes regarding oral healthcare services remains underexplored, necessitating further studies in this context.

METHODS

A mixed method study was conducted, and the quantitative component focused on assessing the oral health status of institutionalized older adults and caregivers' perceptions using a questionnaire. The qualitative part evaluates caregivers' perceptions of providing oral healthcare services for older adults through in-depth interviews.

RESULTS

Mean DMFT among institutionalized older adults was 15.52±8.23. More than 50% of caregivers perceived that the oral health status of institutionalized older adults was fair. Barriers to oral health services include autonomy, difficulty in traveling, lack of financial support, lack of knowledge and time. Approaches to enhancing oral health services for institutionalized older adults include oral health education for older adults and their caregivers, monthly dental visits to the institution, utilization of portable dental chair services, collaboration with dental colleges/dental clinics, distribution of oral health education materials, and provision of oral hygiene aids.

CONCLUSION

Findings from our study indicate the need to collaborate with dental institutions to provide oral health services in old age homes, to improve the oral health status of older adults and caregivers' knowledge.

Exploring medical and dental practitioner perspectives and developing a knowledge attitude and practice (KAP) evaluation tool for the common risk factor approach in managing non-communicable and periodontal diseases

BACKGROUND

The Common Risk Factor Approach (CRFA) is one of the methods to achieve medical-dental integration. CRFA addresses shared risk factors among major Non-communicable Diseases (NCDs). This study aimed to explore the perspectives of dental and medical practitioners concerning CRFA for managing NCDs and periodontal diseases and to create and validate a tool to evaluate the Knowledge, Attitude, and Practice (KAP) of medical and dental practitioners in relation to utilization of CRFA for management of NCDs and Periodontal diseases.

METHODS

This research employed a concurrent mixed-method model and was carried out from January 2021 to February 2022, focusing on medical and dental practitioners in South India. In the qualitative phase, online interviews were conducted with dental and medical practitioners, recorded, and transcribed. Thematic analysis was applied after achieving data saturation. In the quantitative phase, a KAP questionnaire was developed. The sample size was determined by using the G power statistical power analysis program. A sample size of 220 in each group (dentists and medical practitioners) was estimated. Systematic random sampling was used to recruit the potential participants. The data obtained through the online dissemination of KAP tool was analysed and scores were standardized to categorize the KAP.

RESULTS

Qualitative thematic analysis identified four major themes: understanding of common risk factors, risk factor reduction and disease burden, integrating CRFA into clinical practice, and barriers to CRFA. In addition, thematic analysis revealed seventeen subthemes. For the quantitative phase, standardization was applied to a 14-item KAP questionnaire for medical practitioners and a 19-item KAP questionnaire for dental practitioners. The total KAP score for medical practitioners in the study was 21.84 ± 2.87, while dental practitioners scored 22.82 ± 3.21, which indicated a high level of KAP regarding CRFA. Meta integration of qualitative and quantitative data identified eight overarching themes: four were concordant, three were discordant, and one theme provided the explanatory component.

CONCLUSION

The study's structured, validated questionnaire showed that both medical and dental professionals had a high knowledge of CRFA. However, they were not appreciably aware of the risk factors that are shared between NCDs and periodontal disease. Both groups were interested in the idea of using CRFA in integrated medical and dental care.

Prevalence of mild cognitive impairment and its association with malnutrition in older Chinese adults in the community

Objective

This study aims to characterize the prevalence and associated factors of cognitive impairment in older adults within Chinese community settings.

Background

Research exploring the interrelation between malnutrition and cognitive impairment in the older adult community-dwelling population is scarce. The impact of nutritional status on cognitive function in aging adults has not been definitively established.

Methods

A cross-sectional survey was conducted in one urban and one rural community in Chengdu, China, from October 2022 to March 2023. The sample included 706 older adults. Logistic regression was utilized to determine independent risk factors for mild cognitive impairment (MCI).

Results

The study found a significant prevalence of MCI at 32.0% among the older adult population. Among those suffering from malnutrition, 55.6% were affected by MCI. The logistic regression analysis indicated that malnutrition risk (OR = 2.192, 95% CI 1.431 to 3.357, p < 0.001), rural residence (OR = 1.475, 95% CI 1.003 to 2.170, p = 0.048), age (70-79 years old; OR = 2.425, 95% CI 1.611 to 3.651, p < 0.001; ≥80 years old: OR = 4.773, 95% CI 2.571 to 8.859, p < 0.001), male (OR = 1.584, 95% CI 1.085 to 2.313, p = 0.017), middle education level (OR = 0.986, 95% CI 1.627 to 5.482, p < 0.001), and ADL dependence (OR = 1.810, 95% CI 1.158 to 2.827, p = 0.009) were significantly associated with the occurrence of MCI.

Conclusion

The findings indicate a widespread occurrence of MCI in community-dwelling older Chinese adults. The association between malnutrition, as measured by the Mini Nutritional Assessment-Short Form (MNA-SF), and cognitive decline is evident. Older adult individuals with nutritional risk, advancing age, rural residence, male gender, moderate education, and ADL dependency are at increased likelihood of developing MCI. Longitudinal research is needed to clarify the temporal relationships between MCI, demographic factors, and whether improvements in nutritional status or ADL can reduce the incidence of MCI in this population.

Relationship between malnutrition according to the global leadership initiative on malnutrition criteria and oral health among community-dwelling elderly aged 85 years and older: a cross-sectional study

BACKGROUND

A new diagnostic criterion for malnutrition, the Global Leadership Initiative on Malnutrition (GLIM) criteria, has been proposed. Despite a recognized link between malnutrition and oral health, further clarification is needed regarding this association when using the GLIM criteria. This study examined the association between malnutrition and oral health in community-dwelling older adults aged ≥ 85.

METHODS

This study was conducted using data from the Tokyo Oldest Old Survey on Total Health study, and altogether 519 participants ≥ 85 years were enrolled. Malnutrition was assessed using the GLIM criteria. Oral health information, on the number of teeth, maximum occlusal force (MOF), saliva production, denture-related questions (dissatisfaction and frequency of use), dental visit history in the past year, whether participants enjoyed meals, and oral-related quality of life was assessed using the Geriatric Oral Health Assessment Index (GOHAI) were collected. MOF was assessed the average values of three measurements and lower tertile by sex as decline in MOF. For GOHAI, the score for each items (Q1-Q12) was also evaluated, and further, the decline in each item (score: 1-2 points on a 5-point scale) was assessed as a "problem with each items." Oral health factors differing between those with and without malnutrition were analyzed. For differing items, malnutrition risk was evaluated using Cox regression.

RESULTS

Eighty-nine (17.1%) participants experienced malnutrition. Significant differences were observed in the decline in MOF, enjoyment of meals, individual scores for Q2, Q4, and Q6, and the problem with Q3, Q6, Q7, and Q11. Cox regression analysis showed that decline in MOF (odds ratio [OR]: 1.728, 95% confidence interval [CI]: 1.010-2.959), enjoyment of meals (OR: 0.502, 95% CI: 0.289-0.873), problem with Q3 (OR: 5.474, 95% CI: 1.301-23.028), Q6 (OR: 5.325, 95% CI: 1.026-27.636), and Q7 (OR: 2.867, 95% CI: 1.397-5.882) were associated with ORs of malnutrition.

CONCLUSION

Decline in MOF, enjoyment of meals, swallowing problem (problem with Q3), limit contact due to oral condition (problem with Q6), and esthetics problem (problem with Q7) were associated with malnutrition as assessed using the GLIM criteria.

Oral frailty: A concept analysis

AIM

To clarify the concept of oral frailty to provide a clear and standardized conceptual basis for further research in older people.

DESIGN

Rodgers and Knafl's evolutionary concept analysis approach.

METHODS

The narrative analysis detailedly extracted and synthesized the attributes of oral frailty, as well as its antecedents, consequences and related terms under the guidance of Rodgers' evolutionary method.

DATA SOURCES

Multiple databases including Pubmed, CINAHL and Cochrane were searched using selected search terms 'oral frail*', 'oral health' and 'aged' respectively. Articles written between 2013 and 2023 were included, and grey literature was excluded.

RESULTS

A total of 32 articles were included for further analysis and synthesis. The attributes of oral frailty were hypofunction, predisposing in nature, non-specific and multidimensional. Antecedents of prefrailty were classified into four categories, namely, sociodemographic characteristics, comorbidity, physical function and psychosocial factors. Consequences of oral frailty include three themes: increased risk of adverse outcomes, poor nutritional status and possibility of social withdrawal. Related terms that had shared attributes with oral frailty were oral health, functional dentition, oral hypofunction and deterioration of oral function.

CONCLUSIONS

Oral frailty is an age-related phenomenon reflected in decreased oral function. The findings of this concept analysis are conducive to understanding and clarifying the oral frailty, which can help clinicians or other healthcare providers to consider how to distinguish oral frailty in older adults and further promote the development of this field.

IMPACT

Oral frailty is increasingly recognized as an age-related phenomenon reflected in decreased oral function. As it is newly proposed, no consensus has been reached regarding the theoretical and operational concept of it. Through clarifying the concept, this paper will guide future healthcare research on oral frailty regarding the influencing factors, mechanisms and interventions, thus raising the awareness with regard to oral health among older adults. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: In the context of older adults, oral frailty is a concept that requires further research to guide future theoretical development, and the influencing factors, mechanisms and interventions need to be further studied. Raise awareness with regard to oral health among older people and more attention will be paid to the early identification and intervention of oral frailty, so as to further improve the quality of life of older adults.

Oral health inequalities in immigrant populations worldwide: a scoping review of dental caries and periodontal disease prevalence

BACKGROUND

Inequalities in immigrants' oral health are often masked in population-level data. Therefore, this paper was planned to assess the prevalence data on oral health diseases, namely dental caries, and periodontitis, among immigrants worldwide.

METHODS

Following a systematic search in Scopus, Embase, and PubMed for studies published between 2011 and 2023, 1342 records were identified. Following title and abstract screening, 76 studies remained for full-text eligibility-screening based on predefined inclusion criteria. Thirty-two studies were included in the review.

RESULTS

Dental caries figures were higher in immigrant populations compared to the local population, regardless of host countries, age, gender, or nationality. In children, the overall mean and standard deviation (SD) for decayed, missing, and filled teeth in the primary dentition (d3mft) was 3.63(2.47), and for D3MFT (permanent dentition), it was 1.7(1.2). Upon comparing overall mean caries counts in children and adults with their control groups in the included studies, untreated dental caries (D3T and d3t) constituted the dominant share of caries experience (D3MFT and d3mft) in immigrant children. For the local population, the highest proportion of caries experience was attributed to filled teeth (FT and ft). Dentin caries prevalence among immigrants ranged from 22% to 88.7% in the primary dentition and 5.6% to 90.9% in the permanent dentition. Gingivitis ranged from 5.1% to 100%. Oral health varied greatly between studies. Regarding oral health accessibility, 52% to 88% of immigrant children had never been to a dentist, suggesting a very limited level of accessibility to dental health services.

CONCLUSION

It is imperative to develop interventions and policies that have been customized to address the oral health disparities experienced by immigrant populations. Additionally, host countries should actively implement measures aimed at enhancing the accessibility of oral health care services for these individuals. The utilization of available data is crucial in establishing a hierarchy of objectives aimed at enhancing the oral health of immigrant populations.

Association between Number of Teeth and Eating out of Home: A 2019 Statistical Survey of the Japanese Representative Population

Eating out of home (EOH), with its diverse food options, can benefit those with difficulty preparing their meals, especially older adults. Oral health status may be a determinant of EOH, as food accessibility is influenced by oral health, but this association remains unclear. This cross-sectional study used merged data from two national statistical surveys conducted in 2019. Participants were individuals aged ≥ 65 years who responded to both surveys.

Relationship between mastication and malnutrition in community-dwelling older adults: a meta-analysis

PURPOSE

To determine the relationship between mastication and malnutrition in community-dwelling older adults.

RESEARCH STRATEGIES

To establish the eligibility criteria, the acronym PECOS was used: Population: non-institutionalized older adults; Exposure: older adults with malnutrition; Control: older adults without malnutrition; Outcome: masticatory problems in malnourished older adults; Study types: observational studies.

SELECTION CRITERIA

It selected studies assessing malnutrition and mastication difficulties in non-institutionalized adults over 60 years old, of both sexes. Mastication and malnutrition were evaluated with questionnaires on self-reported symptoms and clinical and instrumental assessments. There were no restrictions on language, year of publication, or ethnicity.

DATA ANALYSIS

The included studies were evaluated for methodological quality with the Joanna Briggs Institute tool for cross-sectional studies. For the cross-sectional studies included, the odds ratio (OR) was calculated with 95% confidence intervals.

RESULTS

After searching the databases, 692 references were retrieved, with three studies selected for quantitative and qualitative analysis. The values obtained in the meta-analysis for association show that malnutrition and mastication difficulties were 2.21 times as likely to occur (OR = 2.21; 95%CI = 0.93 - 5.26; I2 = 94%) as individuals without malnutrition (p < 0.001). The assessment of the risk of bias presented a high-risk, a moderate-risk, and a low-risk study. The certainty of evidence was rated very low with the GRADE tool.

CONCLUSION

Individuals at risk of malnutrition are 2.21 times as likely to have mastication difficulties.

Success factors and barriers in interprofessional collaboration between dental hygienists and dietitians in community-dwelling older people: Focus group interviews

INTRODUCTION

Poor nutritional status can impair oral health while poor oral health can influence the individual's dietary intake, which may result in malnutrition. This interaction between nutritional status and oral health in older age requires attention, coordination and collaboration between healthcare professionals. This qualitative study explores dental hygienists' and dietitians' opinions about current collaboration with the aim of identifying success factors and barriers to this interprofessional collaboration.

METHODS

Three focus group interviews were held with Dutch dental hygienists and dietitians about nutritional and oral healthcare in community-dwelling older people.

RESULTS

In total, 9 dietitians and 11 dental hygienists participated in three online focus group interviews. Dental hygienists and dietitians seldom collaborated or consulted with each other. They struggled with the professional boundaries of their field of expertise and experienced limited knowledge about the scope of practice of the other profession, resulting in conflicting information to patients about nutrition and oral health. Interprofessional education was scarce during their professional training. Organizational and network obstacles to collaborate were recognized, such as limitations in time, reimbursement and their professional network that often does not include a dietitian or dental hygienist.

CONCLUSION

Dental hygienists and dietitians do not collaborate or consult each other about (mal)nutrition or oral health in community-dwelling older people. To establish interprofessional collaboration, they need to gain knowledge and skills about nutrition and oral health to effectively recognize problems in nutritional status and oral health. Interprofessional education for healthcare professionals is needed to stimulate interprofessional collaboration to improve care for older people.

Prevalence and Variation of Medical Comorbidities in Oral Surgery Patients: A Retrospective Study at Jazan University

BACKGROUND An aged population is susceptible to chronic diseases, which impacts oral surgery treatment procedures. This retrospective study aimed to evaluate the incidence of medical comorbidities in 640 oral surgery patients treated at the College of Dentistry, Jazan University. MATERIAL AND METHODS This single-center observational study investigated medical records of outpatients who visited Jazan University Dental College Hospital in a 1-year period (2018-2019). Patients’ clinical and radiographic archives were screened to obtain relevant data. Categorical and continuous variables were expressed in terms of frequency and mean values, respectively. Differences in variables were statistically analyzed using the chi-square goodness of fit and proportional test, with a probability value P≤0.05 considered significant. RESULTS Analysis of 640 patient records included records of 300 men and 340 women who underwent oral surgery, of whom 176 patients (27.5%), including 97 men and 79 women, had medical comorbidities. The most common comorbidities were endocrine disease (7.03%), cardiovascular disease (6.71%), respiratory disease (4.53%), and hematological disorders (3.43%). Individual diseases that showed higher prevalence were diabetes mellitus (4.68%), hypertension (3.43%), bronchial asthma (2.65%), and anemia (1.4%). Differences by sex were observed in many individual disorders. CONCLUSIONS Outpatients in oral surgery clinics presented a significant variance in the incidence of medical comorbidities, among which diabetes and hypertension were most common. A proper case history is the best preventive measure that helps a surgeon avert medical emergencies and post-surgical complications.

Oral Frailty as a Risk Factor for Fall Incidents among Community-Dwelling People

BACKGROUND

Identifying older adults with a high risk of falling and providing them with appropriate intervention are vital measures for preventing fall incidents. Scholars report that oral frailty, a decline in oral function, is related to physical function; thus, it bears a potential association with fall risks. This study aimed to investigate the relationship between fall incidents and the status of physical and oral frailty among a sample of residents in Osaka Prefecture.

SUBJECTS AND METHODS

This study targeted community-dwelling people aged 50 years and older who responded to an annual questionnaire survey using a health app for 2 consecutive years, namely, 2020 and 2021. This study analyzed responses from 7591 (62 ± 7 years) participants and determined the status of their oral frailty and comprehensive and physical frailty using the Kihon Checklist.

RESULTS

In the 2020 and 2021 surveys, 17% and 19% of the participants exhibited oral frailty and experienced a fall in the previous year, respectively. Logistic regression analysis demonstrated that oral frailty (adjusted odds ratio: 1.553) and physical frailty as well as low levels of awareness of frailty were significant explanatory variables of the occurrence of fall incidents during the subsequent year.

CONCLUSIONS

Future studies are required to elucidate the mechanisms by which oral frailty induces fall incidents.

A Bibliometric Analysis of Literature on the Impact of Diet on Oral Health

The complex connection between oral health and dietary habits is fundamental to holistic well-being. Oral health is closely linked to dietary choices, both as a reflection and a factor in overall health. This bibliometric analysis investigates clinical trials published in the PubMed database spanning six decades to understand the landscape of research on the impact of diet on oral health. The analysis reveals a fluctuating yet generally increasing trend over the decades, with significant growth periods interspersed with occasional declines, culminating in a recent slight decrease in research output. With strong collaborative networks, Devizio and Proskin emerge as primary contributors. The University of Sydney has published the maximum number of clinical trials. Thematic clusters highlight diverse research facets, including physiological measurements, socio-economic influences, and biochemical aspects. The evolution in research priorities from experimental studies to longitudinal evaluations underscores the interdisciplinary nature of the field. The analysis of country-wise research output revealed that the United States, Germany, and Australia lead in scientific research output, with notable contributions to the global landscape. While larger countries like China and India are represented, their frequencies are relatively lower, suggesting potential areas for further exploration. Collaboration patterns vary between countries, influencing the global impact of their scientific output. Despite the limitations inherent in database selection, this study integrates bibliometric and thematic analyses to offer comprehensive insights into research trends and priorities.

The mediating effect of nutrition on oral frailty and fall risk in community-dwelling elderly people

BACKGROUND

Population aging is accelerating, particularly in Asian countries. Falls are the leading cause of unintentional injuries in the elderly over 60 years old in China. Hence, it is crucial to anticipate the risk factors associated with fall risk. We aimed to explore whether oral frailty and fall risk were reciprocally related and whether nutrition mediated their association.

METHODS

From October 2022 to March 2023, a total of 409 elderly individuals from the Yangzhou community were selected using the convenience sampling method. Cross-sectional data on older adults' oral frailty, nutrition, and fall risk were collected using questionnaires. Data analysis was performed using SPSS 27.0 and PROCESS macro.

RESULTS

The fall risk score was 1.0 (ranging from 0 to 4.0), with 107 cases (26.2%) identified as being at risk of falling. Spearman correlation analysis revealed a positive correlation between oral frailty and the risk of falls (rs = 0.430, P < 0.01). Nutrition was found to have a negative correlation with both oral frailty and fall risk (rs=-0.519、-0.457, P < 0.01). When controlling for covariates, it was observed that nutrition mediated the relationship between oral frailty and falls. The mediating effect value accounted for 48.8% of the total effect (P < 0.01).

CONCLUSIONS

Oral frailty was significantly associated with fall risk, and nutrition might be a mediating factor for adverse effects of oral frailty and fall risk. Enhancing the nutrition of older individuals is a vital approach to mitigating fall risk among those with oral frailty.

Nutrition Status Plays a Partial Mediation Role in the Relationship between Number of Teeth and Frailty: A Cross-Sectional Multicenter Study

INTRODUCTION

Although the relationship between the number of teeth and frailty has been extensively studied, the mediating role of nutrition status in the association between the number of teeth and frailty remains to be clarified.

METHODS

A number of 6,664 participants lived in the communities of West China were analyzed in our study. Physical frailty was determined based on the phenotype established by Fried. Nutrition status was evaluated using the Mini Nutrition Assessment-Short Form (MNA-SF) scale. Multiple linear regression was employed to evaluate the direct relationships between the number of teeth, nutrition, and frailty. Mediation models and structural equation model (SEM) pathway analysis were used to test the mediating role of nutrition status in the relationship between the number of teeth and frailty.

RESULTS

Among the 6,664 participants aged over 50 years old, the prevalence of frailty was 6.2%. Multiple linear regression analysis showed a significant total relationship between the number of teeth (β = -0.359, 95% CI: -0.473 to -0.244, p < 0.001) and frailty. After adjusting for MNA-SF scores, the relationship between the number of teeth and frailty remained significant (β = -0.327, 95% CI: -0.443 to -0.211, p < 0.001), indicating a partial mediating effect of nutrition. Mediation analysis verified that nutrition partially mediated the relationship between the number of teeth and frailty (indirect effect estimate = -0.0121, bootstrap 95% CI: -0.0151 to -0.0092; direct effect estimate = -0.0874, bootstrap 95% CI: -0.1086 to -0.0678) in the fully adjusted model. This mediating effect occurred through influencing weight loss, low level of physical activity, and debility. SEM framework pathway analysis confirmed the association between the number of teeth, nutrition, and frailty.

CONCLUSIONS

Our findings demonstrated that frailty was correlated with the number of teeth and poorer nutritional status, with nutrition partially mediating the correlation between the number of teeth and frailty. Our results supported early nutritional evaluation and intervention in oral health to decrease the risk of frailty.

To assess the contributing factors of nutritional and health status amongst elderlies residing in the nursing homes of fars province, Iran: A cross sectional study

Background and Aims

In line with the global trend, the number of elderly is rising in Iran. It should be noted that the nutritional and health needs of these people, especially those living in nursing houses, are extremely significant. The present study aimed to identify the nutritional and health status and uncover their relationship with received care services by elderlies residing in nursing homes.

Methods

All 373 elderlies living in the nursing homes in Shiraz entered the study, and the requisite data were collected by references to elderlies' files, respective nurses, and elderlies themselves.

Results

The majority of the elderlies were at risk of malnutrition (62.5% of the total population, 55.4% of females, and approximately 44.6% of males). Elderlies with no insurance coverage mainly fell into the at-risk and malnutrition categories. There was a significant relationship between the needs assessment scores, reflecting the need for physical and psychological actions, and elderlies' malnutrition (odds ratio = 1.87, 95% confidence interval: 1.79-1.95). For each unit increase in the Physical and psychological need score, the odds of exposure to malnutrition (vs. nonmalnourished and at risk of malnutrition) was 1.87 times after adjustment for confounders.

Conclusion

The results of our study revealed that most of the elderlies living in the nursing homes of Shiraz had some levels of malnutrition such as at-risk for malnutrition (62.5%) and malnourished (18.9%). Based on these results, it is suggested that health policy-makers take practical steps toward promoting the nutritional care of old people and direct extra supervision to nursing homes and all healthcare provisions.

Research hotspots and trends of oral health in older adults from 2013 to 2023: A bibliometric and visual analysis

Background

Oral health problems seriously affect the quality of life of older adults. It is of great significance to investigate the statuses of oral health in older adults. The study aimed to analyze the current status, hotspots and frontiers of global oral health research in older adults through bibliometrics to provide references and guidance for future research in this field.

Methods

Literature on oral health in older adults from 2013 to 2023 was retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace 6.2.R4 was used for bibliometric and visual analysis, including journal and co-cited journal, country/region, institution, author, co-cited references, and keyword analysis.

Results

A total of 1430 publications related to oral health in older adults were included. The number of publications has gradually increased over the past decade. The most widely published and cited journal was Gerodontology. The most prominent contribution came from the United States of America, and the University of London and Hirohiko Hirano were the most prolific institution and author, respectively. The current research hotspots were summarized as oral hygiene interventions, oral health-related quality of life and oral health issues in older adults. Cohort studies of oral health, the relationship between oral health and frailty, and the correlation between oral health and nutritional status may be emerging research trends.

Conclusions

This study systematically analyzed the hotspots and frontiers of oral health in older adults and called for increased collaboration among countries, institutions, and authors. In addition, oral hygiene interventions for older adults, oral health-related quality of life, oral health issues, cohort studies of oral health, and the relationship between oral health and frailty or nutritional status may be the focus of future research.

Association between animal protein intake, oral frailty and calf circumference in middle-aged and older adults: a cross-sectional analysis from the Shika study

OBJECTIVE

To investigate the relationship between oral frailty (OF), nutrient intake and calf circumference (CC) in middle-aged and older adults.

DESIGN

Cross-sectional study.

SETTING

Residents of four model districts of Shika town, Ishikawa Prefecture, Japan, using data from November 2017 to February 2018.

PARTICIPANTS

One hundred and ninety-four residents aged ≥50 years in four model districts of Shika town. The OF total score ≥3 was defined as OF. Participants were divided into OF and non-OF groups and divided into the low-CC/kg and the high-CC/kg groups.

OUTCOME MEASURES

The primary outcome is to use a two-way analysis of covariance to analyse the interaction between the two CC/kg groups and the two OF groups on nutrition intake. The secondary outcome is to use multiple regression analysis to investigate the nutrients significantly related to CC/kg when stratified by OF, with age, sex, body mass index, drinking status, smoking status and regular exercise as input covariates.

RESULTS

A two-way analysis of covariance revealed a significant interaction between the two CC/kg groups and the two OF groups on animal protein intake (p=0.039). Multiple comparisons using the Bonferroni analysis revealed a significantly lower animal protein intake in the OF group than in the non-OF group with a low CC/kg (p=0.033) but not in the group with a high CC/kg. The multiple regression analysis stratified by OF revealed a positive correlation between animal protein intake and CC/kg (p=0.002).

CONCLUSIONS

The present results revealed a significantly lower animal protein intake in the OF group than in the non-OF group in the low-CC/kg group, but no such difference was observed in the high-CC/kg group. Further longitudinal studies are needed to elucidate this relationship.

The association between oral health status and physical function in elderly patients with acute heart failure

OBJECTIVES

Oral health problems are common and are associated with various geriatric conditions in older adults. The importance of oral health has not been fully highlighted in the assessment and management of patients with heart failure. Here, we investigated the association between oral health status and the decline in physical function during hospitalization in elderly patients with acute heart failure.

MATERIALS AND METHODS

We evaluated oral health using the revised oral assessment guide in 77 patients aged 65 years or older who were admitted to hospital for acute heart failure. Oral health problems were defined as a revised oral assessment guide score ≥9.

RESULTS

Oral health problems were identified in 66.2% of the patients. Patients with oral health problems had high prevalence of decreased physical function, undernutrition, and cognitive impairment. A reduction in the Barthel Index, as an indicator of activities of daily living during hospitalization, was significant in the enrolled patients. The Barthel Index decreased more in patients with oral health problems than those with normal oral health. Furthermore, the revised oral assessment guide score on admission was found to be the only independent predictor of changes in the Barthel Index during hospitalization in the multivariate analyses.

CONCLUSIONS

Oral assessment using the revised oral assessment guide during hospitalization could provide useful information for the management of elderly heart failure patients.

In Vitro Characterization of Reversine-Treated Gingival Fibroblasts and Their Safety Evaluation after In Vivo Transplantation

Reversine is a purine derivative that has been investigated with regard to its biological effects, such as its anticancer properties and, mostly, its ability to induce the dedifferentiation of adult cells, increasing their plasticity. The obtained dedifferentiated cells have a high potential for use in regenerative procedures, such as regenerative dentistry (RD). Instead of replacing the lost or damaged oral tissues with synthetic materials, RD uses stem cells combined with matrices and an appropriate microenvironment to achieve tissue regeneration. However, the currently available stem cell sources present limitations, thus restricting the potential of RD. Based on this problem, new sources of stem cells are fundamental. This work aims to characterize mouse gingival fibroblasts (GFs) after dedifferentiation with reversine. Different administration protocols were tested, and the cells obtained were evaluated regarding their cell metabolism, protein and DNA contents, cell cycle changes, morphology, cell death, genotoxicity, and acquisition of stem cell characteristics. Additionally, their teratoma potential was evaluated after in vivo transplantation. Reversine caused toxicity at higher concentrations, with decreased cell metabolic activity and protein content. The cells obtained displayed polyploidy, a cycle arrest in the G2/M phase, and showed an enlarged size. Additionally, apoptosis and genotoxicity were found at higher reversine concentrations. A subpopulation of the GFs possessed stem properties, as supported by the increased expression of CD90, CD105, and TERT, the existence of a CD106+ population, and their trilineage differentiation capacity. The dedifferentiated cells did not induce teratoma formation. The extensive characterization performed shows that significant functional, morphological, and genetic changes occur during the dedifferentiation process. The dedifferentiated cells have some stem-like characteristics, which are of interest for RD.

The relationship between dysphagia and frailty among Chinese hospitalized older patients: a serial mediation model through self-perceived oral health and self-reported nutritional status

BACKGROUND

Frailty contributes to adverse outcomes in older adults and places a heavy burden on healthcare resources. Dysphagia is associated with frailty, but the mechanisms by which dysphagia affects frailty in older adults are unclear. This study aimed to investigate a serial mediating effect of self-perceived oral health and self-reported nutritional status in the relationship between dysphagia and frailty among hospitalized older patients in China.

METHODS

This cross-sectional study included 1200 patients aged ≥ 65 years in the Department of Geriatrics, Shaanxi Provincial People's Hospital. A structured face-to-face interview was used to survey the following questionnaires: General Information Questionnaire, Tilburg Frailty Indicators (TFI), Eating Assessment Tool-10 (EAT-10), 30mL Water Swallow Test (WST), Geriatric Oral Health Assessment Index (GOHAI), and Short-Form Mini-Nutritional Assessment (MNA-SF). A total of 980 participants with complete data were included in the analysis. Statistical analysis was performed using SPSS 26.0 and Amos 28.0 software. Spearman's correlation analysis was used for correlation analysis of study variables. The results of the multivariate linear regression analysis for frailty were used as covariates in the mediation analysis, and the structural equation model (SEM) was used to analyze the mediating effects among the study variables.

RESULTS

Dysphagia, self-perceived oral health, self-reported nutritional status, and frailty were significantly correlated (P<0.001). Dysphagia was found to directly affect frailty (β = 0.161, 95%CI = 0.089 to 0.235) and through three significant mediation pathways: (1) the path through self-perceived oral health (β = 0.169, 95%CI = 0.120 to 0.221), accounting for 36.98% of the total effect; (2) the path through self-reported nutritional status (β = 0.050, 95%CI = 0.023 to 0.082), accounting for 10.94% of the total effect; (3) the path through self-perceived oral health and self-reported nutritional status (β = 0.077, 95%CI = 0.058 to 0.102), accounting for 16.85% of the total effect. The total mediation effect was 64.77%.

CONCLUSIONS

This study indicated that dysphagia was significantly associated with frailty. Self-perceived oral health and self-reported nutritional status were serial mediators of this relationship. Improving the oral health and nutritional status of hospitalized older patients may prevent or delay the frailty caused by dysphagia.

Poor nutritional status is associated with the severity of omicron infection in the older adults

BACKGROUND

The Omicron wave of Coronavirus disease 2019 (COVID-19) remains the dominant strain worldwide. The studies of nutritional status in geriatric people with COVID-19 Omicron variant are limited. Thus, the aim of this study was to investigate the incidence of poor nutritional status among Omicron infected older patients, and to explore the correlation between the nutritional status and the severity of Omicron infection in older patients.

METHODS

This is a retrospective cross-sectional study. According to the clinical symptoms, patients were divided into two groups: mild and moderate to severe. Mini Nutritional Assessment short-form (MNA-SF) was conducted when patients were admitted and poor nutritional status was defined as MNA-SF score of 0-11. The inflammatory markers including neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR) and systemic inflammatory index (SII) were calculated and compared between two groups.

RESULTS

Total of 324 patients were enrolled, with median [interquartile range (IQR)] age of 73 (17) years. Overall, 241 cases were mild, 83 cases were moderate to severe at the time of diagnosis and that 54.3% of patients had poor nutritional status. Patients with poor nutritional status were found to be older (P < 0.001) and less vaccinated (P < 0.001), with a longer virus shedding duration (P = 0.022), more comorbidities (≥ 2) (P = 0.004) and higher value of NLR (P < 0.001), PLR (P < 0.001) and SII (P = 0.012). Vaccination, cycle threshold value in ORF1ab gene (OR CT value) and female, higher MNA-SF score was negatively connected with probability of moderate to severe infection. For every 1 score increase in MNA-SF, the odds ratio of moderate to severe infection decreased by 14.8% [adjusted odds ratio (aOR), 0.852; 95% confidence interval (CI): 0.734-0.988; P = 0.034].

CONCLUSIONS

Older patients with poor nutritional status are more likely to develop moderate to severe Omicron infection.

Oral frailty among dentate and edentate older adults in long-term care

BACKGROUND

The objectives of this study were to compare oral frailty (OFr) among edentate and dentate older adults living in long-term care facilities (LTCF) and to clarify how edentulism and oral disease burden (ODB) of dentate older adults are associated with OFr.

METHODS

The population of this study comprised 94 edentate and 209 dentate residents in LTCF in Helsinki, Finland, who had previously participated in a nutritional study. The participants underwent a clinical oral examination. The dentate residents were further divided into three ODB groups based on asymptotic dental score. The edentate and different ODB groups were compared with each other regarding demographics and oral and medical findings. OFr was defined as ≥ 2 of following: having a diet of soft/pureed food, residue of food in the oral cavity, inability to keep the mouth open during examination, unclearness of speech, dry mouth. The association between OFr and edentulousness and various levels of ODB was analyzed by a multivariate logistic model.

RESULTS

Participants with low ODB had significantly less OFr than their edentate peers (p = 0.009). Furthermore, the edentate and dentate with high ODB had similar odds for OFr.

CONCLUSIONS

Edentulousness and high ODB are equally harmful conditions and may predispose to OFr. This study suggests that maintaining healthy natural teeth and good oral health (low ODB) may protect against OFr.

TRIAL REGISTRATION

The Ethics Committee of the Hospital District of Helsinki and Uusimaa approved the protocols for the nutritional status and oral healthcare studies and the merging of the data, including patient medical records (Register number HUS/968/2017).

Oral health and healthy ageing: a scoping review

BACKGROUND

Good oral health is an important part of healthy ageing, yet there is limited understanding regarding the status of oral health care for older people globally. This study reviewed evidence (policies, programs, and interventions) regarding oral health care for older people.

METHODS

A systematic search of six databases for published and grey literature in the English language by the end of April 2022 was undertaken utilising Arksey and O'Malley's scoping review framework.

RESULTS

The findings from oral health policy documents (n = 17) indicated a lack of priorities in national health policies regarding oral health care for older people. The most common oral health interventions reported in the published studies (n = 62) included educational sessions and practical demonstrations on oral care for older adults, nurses, and care providers. Other interventions included exercises of facial muscles and the tongue, massage of salivary glands, and application of chemical agents, such as topical fluoride.

CONCLUSION

There is currently a gap in information and research around effective oral health care treatments and programs in geriatric dental care. Efforts must be invested in developing guidelines to assist both dental and medical healthcare professionals in integrating good oral health as part of healthy ageing. Further research is warranted in assessing the effectiveness of interventions in improving the oral health status of the elderly and informing approaches to assist the integration of oral health into geriatric care.

Denture use and risk for cardiometabolic disease: observational and Mendelian randomization analyses

AIMS

Denture use may potentially increase the risk of cardiometabolic diseases (CMDs), but the casual relevance and strength of the associations are currently unknown.

METHODS AND RESULTS

A total of 495 938 participants from the UK Biobank were included in the observational analyses. Linkage disequilibrium score (LDSC) regression and Mendelian randomization analyses were employed to estimate genetic correlation and the associations between the genetic liability for denture use with coronary artery disease, myocardial infarction, heart failure (HF), any stroke (AS), ischaemic stroke, haemorrhagic stroke, type 2 diabetes (T2D), and related clinical risk factors. In observational analysis, denture use was associated with 14-25% higher risks of various CMDs. The LDSC analysis found that denture use showed a positive genetic correlation with CMDs (rg 0.21-0.38). Genetic liability for denture use was associated with an elevated risk of HF [odds ratio: 1.49 (1.20-1.83)] and T2D [1.11 (1.01-1.24)]. By integrating genetic summary data of denture use with the sum of decayed, missing, and filled tooth surfaces (DMFS), a clinical measure of dental caries obtained from an independent source, genetically determined denture use/DMFS was also associated with an elevated risk of AS [1.21 (1.04-1.40)]. Furthermore, genetically predicted denture use/DMFS was significantly associated with established cardiometabolic risk factors, including HDL cholesterol, triglycerides, waist circumference, waist-to-hip ratio, and height.

CONCLUSION

Our study supported potential causal associations between the genetic liability for denture use and risks for HF, AS, T2D, and related clinical risk factors. These findings may inform prevention and intervention strategies targeting dental diseases and CMDs.

Exploring Oral Function, Protein Intake, and Risk of Sarcopenia: A Scoping Review

INTRODUCTION

Sarcopenia is loss of both muscle mass and function with age and is associated with inadequate protein intake. However, evidence to suggest an association with oral health is less clear.

OBJECTIVE

To scope peer-reviewed published evidence (2000-2022) pertaining to oral function in relation to sarcopenia and/or protein intake in older people.

METHODS

CINAHL, Embase, PubMed, and Scopus were searched. Included were peer-reviewed studies measuring oral function (e.g., tooth loss, salivary flow masticatory function, strength of muscles of mastication, and tongue pressure) and a measure of protein intake and/or a measure of sarcopenia (appendicular muscle mass and function). Full article screening was conducted by 1 reviewer with a random 10% screened in duplicate by a second reviewer. Relevant content pertaining to study type, country of origin, measures of exposure, and outcomes and key findings was mapped and the balance of data showing a positive versus null association of oral health with outcomes charted.

RESULTS

Of 376 studies identified, 126 were screened in full, yielding 32 included texts, of which 29 were original articles. Seven reported intake of protein and 22 reported measures of sarcopenia. Nine distinct oral health exposures were identified, with ≤4 studies relating to any one of these measures. Most data were cross-sectional in nature (27 studies) and from Japan (20 studies). The balance of data showed associations between tooth loss and measures of sarcopenia and protein intake. However, the balance of data pertaining to any association between chewing function, tongue pressure, or indices of oral hypofunction and sarcopenia was mixed.

CONCLUSION

A broad range of oral health measures have been studied in relation to sarcopenia. The balance of data suggests that tooth loss is associated with risk, but data pertaining to the oral musculature and indices of oral hypofunction are mixed.

KNOWLEDGE TRANSFER STATEMENT

The findings of this research will increase awareness among clinicians of the amount and nature of evidence pertaining to the relationship between oral health and risk of compromised muscle mass and function, including data showing that loss of teeth is associated with increased risk of sarcopenia in older people. The findings highlight to researchers the gaps in the evidence and where further research and clarification of the relationship between oral health and risk of sarcopenia is warranted.

Prevention of oral diseases for the older person (Part 1)

Older adults often experience poorer levels of oral health than younger adults, especially if they have become dependent on a third party to support their daily oral care routine. However, the deterioration of oral health does not need to be a part of the ageing process. Most oral diseases are largely preventable with the daily removal of dental plaque that forms on teeth and dentures, using a fluoride toothpaste, eating a healthy diet and reducing any tobacco consumption. The dental team have a duty of care to ensure that older people receive evidence-based oral health preventative advice tailored to the individual, taking into account individual risk factors that can increase with age. This can include the clinical application of topical fluoride and minimally invasive dentistry. Older people at an increased risk of poor oral health include those with cognitive conditions, physical impairments and certain medical conditions. Care home residents face particular barriers to attaining a satisfactory standard of oral care which are discussed herein. Good oral health preventative routines must be established early after the diagnosis of progressive chronic conditions and will help to prevent the need for dental intervention later in life when treatment can be more difficult to tolerate. Inclusion of oral health prevention within health policy and legislation is necessary to improve the oral health for older people living in all health and care settings.

Rheumatoid Arthritis and Osteoarthritis in Adult Women: A Functional Approach to the Stomatognathic System

Rheumatoid arthritis and osteoarthritis both affect the articular cartilage, and are characterized by signs and symptoms that can affect the functions of the human body. This cross-sectional observational study evaluated electromyographic activity in the masseter and temporalis muscles, molar bite force, and mandibular mobility in adult women with rheumatoid arthritis or osteoarthritis. A total of 42 women were distributed into 3 groups: rheumatoid arthritis group (ARG, n=14); osteoarthritis group (OAG, n=14); and a healthy control group (CG, n=14). Electromyography was used to evaluate mandibular tasks at rest, right and left laterality, protrusion, and dental clenching during maximum voluntary contraction, with and without parafilm, and a dynamometer was used to analyse the right and left molar bite forces. A digital caliper was used to measure the range of mandibular movement for maximum mouth opening, right and left laterality, and protrusion. Statistical analyses were performed, including analysis of variance and Tukey's test (P<0.05). Electromyography showed no significant differences between the groups when evaluating the masticatory muscles during the mandibular tasks. Significant difference was observed between the ARG and CG, however, in the maximum right (P=0.007) and left (P=0.02) molar bite forces. Significant difference was observed in the maximum mouth opening of the ARG and OAG groups compared with that of the CG (P=0.009), suggesting that adult women with rheumatoid arthritis or osteoarthritis experience functional alterations in the stomatognathic system, particularly in molar bite force and maximum mouth opening.

Association between nutritional risk status and health related quality of life: An investigation on the aging patients with cardiovascular disease

Introduction

Acknowledging the considerable influence of undernutrition on health outcomes and HRQOL, this study sought to appraise the nutritional risk status of elderly patients with cardiovascular diseases (CVD) through the utilization of the Nutritional Risk Screening (NRS). Additionally, the investigation aimed to evaluate the correlation between NRS status and HRQOL within the context of patients referred to a cardiac hospital in Tabriz, Iran.

Methods

This cross-sectional study was conducted in Tabriz, Iran. The participants were selected randomly from patients referring to Shahid Madani Heart Hospital, a comprehensive university hospital during July to December 2018. A linear regression was used for control of confounding variables (age, gender, education level, marital status, and income levels) and predict the relationship between nutrition risk status and HQRL.

Results

Of the 200 patients with CVD participated in this study, 68 (34%) of participants had normal nutrition status, 108 (54%) were at risk for undernutrition, and 24 (12%) had undernutrition. A total of 24 aging patients with undernutrition, 13 (54%) were divorced or widowed. 86% of patients with diabetes were at risk for undernutrition and 13.9% had undernutrition. There were statistically significant relationship between undernutrition and HRQOL dimensions, age, gender, and marital status.

Conclusion

The study revealed a correlation between elevated undernutrition scores in patients and factors such as older age, female gender, and marital status of being divorced or widowed. Furthermore, the results imply that a notable elevation in the risk score for undernutrition in patients is significantly linked to impaired HRQOL among elderly individuals with CVD.

Oral Function for Diagnosing Oral Hypofunction in Healthy Young Adults: A Comparison with the Literature

This study investigated decline in oral function in healthy young adults and compared it with that observed in an earlier studies employing older adults. The participants comprised 130 young healthy adults (mean age 24.1±2.9 yr), all with complete dentition. All participants underwent the oral hypofunction test established by the Japanese Society of Gerodontology, which evaluates oral hygiene, oral dryness, occlusal force, tongue-lip motor function (oral diadochokinetic rate; ODK), tongue pressure, and masticatory and swallowing function. The average value for and rate of hypofunction of each parameter were calculated. In healthy young adults, the scores were 28.9±17.1% for oral hygiene; 28.8±2.2 for oral dryness; 959.9±499.8 N for occlusal force; 7.0±0.8 times/sec for ODK /pa/, 7.6±0.8 times/sec for /ta/, and 6.9±0.9 times/sec for /ka/; 41.8±8.4 kPa for tongue pressure; 249.8±94.1 mg/dl for masticatory function; and 0.2±0.7 for swallowing function. No sign or symptom of change in oral function was observed at a high rate in young adults. Occlusal force, tongue-lip motor function, and tongue pressure showed a large difference in the rate of hypofunction between younger and older adults, however.
