RESUMEN
OBJECTS: This study aimed to determine the association between annual medical expenses and oral frailty in later-stage older adults (aged ≥ 75 years). No studies have investigated the association between medical costs and oral frailty, which would elucidate the association between oral frailty and the deterioration of mental and overall physical function. MATERIALS AND METHODS: In this cross-sectional study, 2190 adults (860 men and 1330 women aged 75-94 years) covered by the Medical System for the Elderly and residing in Tottori Prefecture, Japan, between April 2016 and March 2019, were included. Participants were classified into three groups: healthy, pre-orally frail or orally frail, based on dental health screening findings. The medical and dental expenses over the years, number of days of consultations and comorbidities were obtained from the Japanese Health Insurance Claims Database. RESULTS: The number of days of medical and dental consultations and annual medical expenses for outpatient care differed among the three study groups. A significant association was observed between oral frailty and high annual expenses for outpatient medical and dental care. Oral frailty was associated with higher medical expenses in participants with poor masticatory function. Higher and lower dental expenses were associated with subjective poor masticatory function and subjective impairment of swallowing function respectively. CONCLUSION: Medical and dental expenses for orally frail older adults are high, indicating that oral frailty may be related to the occurrence and severity of diseases other than oral health issues. Future studies should examine the mechanism by which oral weakness affects physical and mental functions.
RESUMEN
BACKGROUND: Prevotella bacteria are associated with inherent diseases of the oral cavity, such as periodontal disease, and systemic diseases. Oral frailty (OF) has been associated with nursing necessity and death. However, the relationship between OF and oral microbiota has not been fully clarified. OBJECTIVE: This cross-sectional study investigated the association between OF and Prevotella percentage in the oral microbiota of community-dwelling older adults. METHODS: Oral bacteria species from saliva were identified in 208 community-dwelling older individuals aged ≥60 years in Japan. The proportion of Prevotella in the oral microbiota was classified into three tertile groups, and its relationship with each test item for OF (number of remaining teeth, masticatory performance, oral diadochokinesis, tongue pressure, difficulties eating tough foods, difficulties swallowing tea or soup, number of applicable OF judgement items, and existence of OF) was examined using ordinal logistic regression analysis. RESULTS: The Prevotella proportions were classified into lower, middle and upper groups, comprising 70, 69 and 69 participants, respectively. The three groups showed a significant relationship between the number of remaining teeth (odds ratio [OR]: 0.946, 95% confidence interval [CI]: 0.915-0.977), masticatory performance (OR: 0.897, 95% CI: 0.844-0.953), number of applicable OF judgement items (OR: 1.477, 95% CI: 1.14-1.915), and existence of OF (OR: 4.194, 95% CI: 1.519-11.576). CONCLUSION: The proportion of Prevotella in oral microbiota was high in individuals with OF. Among the older adults, the type of oral microbiota and systemic diseases may be related to the examination and management of oral function decline.

AIM: Efforts to combat frailty and preserve good health in older adults have highlighted oral frailty as an early indicator of overall frailty. Individuals showing oral frailty are at an elevated risk of insufficient nutritional intake compared with those without oral frailty; however, underlying mechanisms remain poorly explored. In this cross-sectional study, we aimed to examine the link between oral frailty and undernutrition, especially regarding poor appetite and low dietary diversity. METHODS: The analysis included 2727 late-stage older adults (mean age 79.9 ± 4.3 years) who underwent dental checkups in a prefecture in Japan from 2016 to 2020. The examination involved a questionnaire survey (covering basic information, frailty screening index, appetite index: Simplified Nutritional Appetite Questionnaire; and dietary variety: Dietary Variety Score) and a measurement survey (including intraoral confirmation, oral diadochokinesis and masticatory efficiency test). Individuals with three or more indications of poor oral function, identified through oral function assessment, were defined as showing oral frailty. Binomial logistic regression and path analyses examined associations among oral frailty, Simplified Nutritional Appetite Questionnaire and Dietary Variety Score. RESULTS: Among those analyzed, 1208 (44.3%) participants were categorized into the oral frailty group. Binomial logistic regression analysis showed that Simplified Nutritional Appetite Questionnaire (odds ratio for oral frailty per 1-point increase 0.88, 95% confidence interval 0.84-0.93) and Dietary Variety Score (odds ratio 0.95, 95% confidence interval 0.92-0.98) were significantly associated with oral frailty. The path analysis showed individual associations between each examined factor. CONCLUSIONS: Oral frailty was associated with decreased appetite and dietary variety in late-stage older adults.

Oral function evaluation in older adults with dementia is important for determining appropriate and practical dietary support plans; however, it can be challenging due to their difficulties in comprehending instructions and cooperating during assessments. The feasibility of oral function evaluation has not been well studied. This cross-sectional study aimed to determine the feasibility of oral function evaluation in older adults with Alzheimer's disease (AD) according to Functional Assessment Staging of Alzheimer's Disease (FAST) stages. In total, 428 older adults with AD (45 men and 383 women; mean age: 87.2 ± 6.2 years) were included. Multilevel logistic regression models were used to examine the prevalence of participants who were unable to perform oral function evaluations, including oral diadochokinesis (ODK), repeated saliva swallow test (RSST), and modified water swallow test (MWST). In comparison to the reference category (combined FAST stage 1-3), FAST stage 7 was associated with the infeasibility of ODK (adjusted odds ratio, 95% confidence interval = 26.7, 4.2-168.6), RSST (5.9, 2.2-16.1), and MWST (8.7, 1.6-48.5, respectively). Oral function evaluation is difficult in older adults with severe AD. Simpler and more practical swallowing function assessments and indicators that can be routinely observed are required.

Protein amyloids have attracted attention for their application as functional amyloid materials because of their strong properties, such as high resistance to chemical or biological degradation, despite their medical issues. Amyloids can be used for various applications by modifying the amyloid surface with functional materials, such as proteins and polymers. In this study, we investigated the effect of polyallylamine (PAA), a functional cationic polymer as a candidate for amyloid modification, on the amyloids formed from amyloid ß (Aß) peptide. It was demonstrated for the first time that PAA can bind to Aß amyloids through fluorescence observations and the quenched emission from the tyrosine at site 10 near the fibrillogenic core. These results suggest that PAA could be used to develop new functional amyloids. However, notably, coating Aß amyloid with PAA could affect conventional amyloid detection assays such as thioflavin T assay and detection using antibodies. Thus, our results also indicate that consideration would be necessary for the analysis of functional amyloids coated with various polymers.

Social isolation among older adults affects their physical and mental health. Ego-resilience is associated with flexible adaptation to various environments and acceptable behaviors. However, its association with social isolation among older people is unclear. Therefore, a health survey was conducted with 510 adults aged 65 years or older to assess social isolation, its associated factors, and ego resilience. The results showed that the social isolation group had a lower median ego-resiliency scale score (42.0) compared to the non-social isolation group (38.0). The social isolation group were mostly males without spouses, took time to move, had more depressive moods, and poorer subjective health status. The non-social isolated group had faster maximum walking speed. Low ego-resilience was newly identified as a factor associated with social isolation among older people, as were being male, having no spouse, and depressive symptoms. Mediation analysis revealed that ego-resilience affected social isolation and was partially mediated by depressive symptoms.
RESUMEN
OBJECTIVES: Building upon our recently developed conceptual definition of oral frailty (the age-related functional decline of orofacial structures), this e-Delphi study aims to develop an operational definition of oral frailty by identifying its components. METHODS: We used a modified e-Delphi study to reach a consensus among international experts on the components of oral frailty. Twelve out of fifteen invited experts in the field of gerodontology participated. Experts responded to three rounds of an online 5-point scale questionnaire of components to be included or excluded from the operational definition of oral frailty. After each round, scores and rationales were shared with all experts, after which they could revise their position. A consensus was reached when at least 70% of the experts agreed on whether or not a component should be included in the operational definition of oral frailty. RESULTS: The experts achieved a high level of agreement (80 - 100%) on including eight components of oral frailty and excluding nineteen. The operational definition of oral frailty should include the following components: 1) difficulty eating hard or tough foods, 2) inability to chew all types of foods, 3) decreased ability to swallow solid foods, 4) decreased ability to swallow liquids, 5) overall poor swallowing function, 6) impaired tongue movement, 7) speech or phonatory disorders, and 8) hyposalivation or xerostomia. CONCLUSION: This e-Delphi study provided eight components that make up the operational definition of oral frailty. These components are the foundation for the next stage, which involves developing an oral frailty assessment tool.

Background: The systemic inflammatory response following surgery as well as that of malignant disease itself is associated with a hypercoagulable state, and thromboprophylaxis is thus recommended during postoperative management of cancer patients. However, limited information is available on the prevalence of preoperative deep vein thrombosis (DVT) and its risk factors in surgical candidates, especially those receiving operations for benign diseases. Methods: This is a retrospective observational study with data of all patients scheduled for elective general surgery between January 2011 and September 2020, undergoing lower extremity venous ultrasonography as preoperative screening for DVT. The prevalence of preoperative asymptomatic DVT was estimated and its associations with clinical variables were evaluated. Results: Among 1512 patients included in the study, 161 (10.6%) had asymptomatic DVT before surgery. DVT prevalence was 13.7% in patients with malignant disease, while it was 8.6% in those with benign disease. The site of the thrombus was distal type in 141 (87.6%) patients, most commonly in the soleal vein. Advanced age (>70 years), female sex, and decreased hemoglobin level were significantly associated with preoperative asymptomatic DVT by multivariate analysis. The odds ratio for advanced age was the highest and rose as age increased. Malignant disease was not an independent risk factor for preoperative DVT. Conclusion: This study showed the prevalence of asymptomatic DVT to be equal in patients with and without malignant disease undergoing elective general surgery. Preoperative DVT assessment is necessary regardless of the disease indicated for surgery, especially in patients with the risk factors identified in this study.
RESUMEN
AIM: To assess the validity of self-reported articulatory oral motor skill against objectively measured repetitive articulatory rate (oral diadochokinesis [oral-DDK]) as a gold standard index for articulatory oral motor skill in community-dwelling older Japanese adults. METHODS: This cross-sectional study included 607 Japanese adults (mean age = 73.9 years). A single-item self-report questionnaire for articulatory oral motor skill was developed. Study participants completed a 1-month-interval test-retest protocol to assess reliability of the questionnaire, and the protocol was tested by the kappa statistic. Oral-DDK with /ta/ (i.e., the number of repetitions of the monosyllable /ta/ per second) was measured during the on-site examination. Low oral-DDK performance was defined as <5.2 times/s in men and <5.4 times/s in women. Oral-DDK performance, oral functions other than articulatory oral motor skill, and physical frailty were compared in the groups with and without self-reported low articulatory oral motor skill as determined by the response to the questionnaire. RESULTS: Self-reported low articulatory oral motor skill was identified in 18.5% of the study population. The self-report questionnaire had good test-retest reliability, with a kappa statistic of 0.71. Self-reported low articulatory oral motor skill was significantly associated with a lower value of oral-DDK with /ta/ and a higher proportion of low oral-DDK performance, difficulties in chewing and swallowing, dry mouth, and physical frailty. Self-report had high specificity (83.1%) but low sensitivity (42.1%) for detecting low oral-DDK performance. CONCLUSIONS: A single-item self-report questionnaire for articulatory oral motor skill had acceptable test-retest reliability and was associated with objectively measured articulatory oral motor skill.

This 1-year multicenter prospective cohort study aimed to determine the association between observable eating and swallowing function factors and outcomes (death/hospitalization or survival) among elderly persons in long-term care insurance facilities in Japan. Baseline assessments of factors, such as language, drooling, halitosis, hypersalivation, tongue movement, perioral muscle function, coughing, respiration after swallowing, rinsing, and oral residue, among others, were conducted. A score of 0 was considered positive, and a score of 1 or 2 was considered negative. Patient age, sex, body mass index, Barthel index, and Clinical Dementia Rating were recorded. The death/hospitalization or survival rates over 1 year were recorded, and patients were allocated into groups depending on the respective outcome (death/hospitalization group or survival group) and baseline characteristics. A total of 986 residents from 32 facilities were included, with 216 in the death/hospitalization group and 770 in the survival group. Language, salivation, halitosis, perioral muscle, coughing, respiration after swallowing, rinsing, and oral residue were significantly associated with the outcomes (p < 0.05). Therefore, routine performance of these simple assessments by caregivers may allow early detection and treatment to prevent death, pneumonia, aspiration, and malnutrition in elderly persons.
RESUMEN
AIM: To evaluate the association between vitamin D status and periodontal inflammation as determined by the periodontal inflamed surface area (PISA) in community-dwelling older adults. MATERIALS AND METHODS: This cross-sectional study included 467 Japanese adults (mean age = 73.1 years) who underwent full-mouth periodontal examinations and measurements of serum levels of 25-hydroxyvitamin D (25(OH)D). We used linear regression and restricted cubic spline models to analyse the association between exposure (serum 25(OH)D) and outcome (PISA). RESULTS: The linear regression model showed that, after adjusting for potential confounders, participants in the lowest quartile of serum 25(OH)D had 41.0 mm2 more PISA (95% confidence interval [CI]: 4.6-77.5) than the reference group (the highest quartile of serum 25(OH)D). The spline model showed that the association between serum 25(OH)D and PISA was non-linear and restricted to the low 25(OH)D range. PISA initially sharply decreased as serum 25(OH)D increased, and then the decreasing trend slowed and plateaued. The inflection point with the minimum PISA value was a serum 25(OH)D level of 27.1 ng/mL, above which there was no decreasing trend in PISA with increasing serum 25(OH)D levels. CONCLUSIONS: Low vitamin D status had an L-shaped association with periodontal inflammation in this cohort of Japanese adults.

Oral hygiene management issues vary across types and clinical stages of dementia. We aimed to clarify the issues related to oral hygiene management in older adults with Alzheimer's disease (AD) according to stages defined by the Functional Assessment Staging of Alzheimer's Disease (FAST). In all, 397 records (45 men and 352 women; average age, 86.8 years; age range, 65-106) from older adults with AD were used for the cross-sectional study. We used data from a cohort of older adults (≥65 years old) who required long-term care and lived in the Omorimachi area of Yokote City, Akita Prefecture, Japan. Multilevel logistic regression analysis was conducted to examine the associations of the FAST stage, set as the exposure variable, with oral hygiene management parameters set as outcome variables. Compared to the reference category (combined FAST stage 1-3), FAST stages 6 and 7 had significantly higher odds ratios for refusal of oral health care, dependence in performing oral health care, and rinsing and gargling disability. FAST stages 4 and 7 were associated with dental plaque accumulation. Oral health care for older adults with AD should be planned appropriately according to dementia severity.

Oral frailty, overlapping a decline in multi-faceted oral functions and often seen in older adults, increases risks of adverse health outcomes, thereby necessitating earlier measures. Tooth loss, a major element of oral frailty, is mainly caused by periodontal disease and is an irreversible event. Therefore, this study aimed to clarify whether advanced periodontal disease increases the risks of "new-onset" oral frailty through a longitudinal analysis based on the 2012 baseline survey of the Kashiwa cohort and the follow-up assessments conducted in 2013, 2014, 2016, and 2018. The participants were disability-free, non-orally frail older adults living in Kashiwa City. Of the 1234 participants (72.2 ± 5.1 years old; 50.8% men) analyzed in this study, oral frailty occurred in 23.1% within the six-year period. The group with Community Periodontal Index (CPI) ≥ 3 at baseline had no significant difference in the risk of oral frailty compared with CPI ≤ 2; however, CPI4 at baseline was related to the increased risk of oral frailty compared with CPI ≤ 3 (an adjusted hazard ratio (95% confidence interval): 1.42 (1.12-1.81). Conclusively, severe periodontitis (CPI4) might be associated with new-onset oral frailty, suggesting that prevention of periodontal disease could contribute to oral frailty prevention.
RESUMEN
BACKGROUND: Few studies have examined the state of oral function in older adults with sarcopenia. We assessed the oral functions of community-dwelling older adults with sarcopenia from multiple perspectives to clarify their potentially low oral function. METHODS: A total of 1517 (86.2%; 990 women, 527 men; mean age 76.1 ± 7.6 years) participants were included in this study. Grip strength, gait speed and skeletal muscle mass index were assessed, and sarcopenia was evaluated according to the criteria of the Asian Working Group for Sarcopenia 2019. The degree of tongue coating, oral moisture, occlusal force, tongue-lip motor function, tongue pressure, masticatory function and swallowing function were assessed. The criteria for oral hypofunction (a disease that is a combination of multiple low oral functions) were used to assess oral function. Statistical analyses were performed using Kolmogorov-Smirnov test, unpaired t-test, Mann-Whitney U test, χ2 test, and univariate and multivariable logistic regression analyses, with each oral function as the dependent variable and sarcopenia as one of the independent variables. The significance level was set at P < 0.05. RESULTS: The prevalence rates of sarcopenia and severe sarcopenia were 14.2% and 3.8%, respectively. The prevalence of oral hypofunction was 39.9%. Compared with the robust group, the sarcopenia and severe sarcopenia groups tended to have a higher frequency of the following components (all P < 0.01): low occlusal force, low tongue-lip motor function, low tongue pressure, low masticatory function, low swallowing function and oral hypofunction. Univariate logistic regression analysis showed that sarcopenia was associated with low occlusal force, low tongue-lip motor function, low tongue pressure, low masticatory function, low swallowing function and oral hypofunction. The odds ratios and 95% confidence intervals of sarcopenia for each oral function were 2.62 [2.00, 3.43], 2.21 [1.69, 2.89], 3.66 [2.79, 4.81], 3.23 [2.46, 4.25], 1.66 [1.26, 2.20] and 3.59 [2.72, 4.72], respectively. Multivariable logistic regression analysis showed that sarcopenia was associated with low occlusal force (1.63 [1.10, 2.40]), low tongue pressure (2.28 [1.65, 3.15]), low masticatory function, (1.94 [1.27, 2.97]), low swallowing function (1.64 [1.17, 2.28]) and oral hypofunction (2.17 [1.52, 3.09]). CONCLUSIONS: This study demonstrated that multiple aspects of oral function were low among community-dwelling older adults with sarcopenia. The potential decline in oral functions in older adults with sarcopenia may have been overlooked until now. This study indicates the need for dental perspectives in intervening with older adults with sarcopenia and the need to encourage them to see dental professionals.

PURPOSE: To establish age- and sex-specific population reference values for tongue pressure (TP) in community-dwelling Japanese older adults. METHODS: For this analysis, we pooled four population-based studies on community-dwelling adults aged ≥65 years that measured TP using a JMS tongue pressure measuring device. We calculated the means and deciles of TP per 5-year age group for each sex. We also estimated age trends in TP for men and women. RESULTS: In total, 5,083 individuals (2,150 men and 2,933 women, with a mean [standard deviation] age of 75.2 [6.5] years) were included in the present analysis. In male participants, the mean (standard deviation) TPs for ages 65-69, 70-74, 75-79, 80-84, and ≥85 years were 34.0 (8.4), 32.2 (8.1), 30.8 (8.3), 28.4 (8.9), and 24.4 (8.2) kPa, respectively. In female participants, the corresponding values were 31.5 (7.1), 30.5 (7.5), 29.6 (7.3), 28.4 (8.0), and 26.4 (7.6) kPa, respectively. For both sexes, there were significant declining trends in TP with advanced age. In addition, the interaction between age and sex had a significant effect on TP (regression coefficient [95% confidence interval] = -0.18 [-0.25 to -0.11] when age was modeled as a continuous variable and sex was modeled as a categorical variable [coded as 0=women, 1=men]). CONCLUSIONS: This study determined age- and sex-specific reference values for TP, presented as means and deciles, in community-dwelling Japanese older adults aged ≥65 years. This study also demonstrated sex differences in age-related declines in TP.

PURPOSE: This study aimed to determine whether denture use contributes to maintaining and improving food forms in long-term care facility (LTCFs) residents. METHODS: In 888 residents of 37 LTCFs in Japan, the following were investigated: nutritional intake status, food forms, age, sex, Barthel index (BI), clinical dementia rating (CDR), number of teeth present, number of occlusal supports, swallowing function, and use of dentures. Among all residents, those who were well-nourished and had ≤9 occlusal supports were analyzed. Based on standardized criteria, the food forms consumed by the subjects were divided into two groups: dysphagia and normal diet, which were further classified into four levels. Analysis was performed using a generalized estimation equation with the four levels of food forms as dependent variables and age, sex, BI, CDR, presence of dysphagia, number of teeth present, and use of dentures as independent variables. RESULTS: The final analysis included 622 (70.0%) residents. Of these, 380 (61.1%) used dentures. The analyses revealed that food form was significantly associated with age (adjusted odds ratio [OR], 0.98), BI (OR, 1.04), number of teeth present (OR, 1.03), presence of dysphagia (OR, 0.44), and use of dentures (OR, 2.82). CONCLUSIONS: Denture use was associated with food forms among Japanese LTCF residents. This indicates that the use of dentures is related to the maintenance of food forms, even in the elderly who participate in few activities of daily living, have reduced cognitive function, and require long-term care.

This study examined the association between coronavirus disease 2019 (COVID-19)-related stress, exercise habits, and oral health-related quality of life (OHRQoL) in a sample of 215 community-dwelling older adults in Japan (57 men, 158 women; Mage = 74.2 years, SD = 6.0). Data were collected during wellness checkups in October 2020 and included participants' demographic characteristics, measures of instrumental activities of daily living and depressive tendencies, number of teeth, oral hypofunction, OHRQoL, COVID-19-related stress, and exercise habits. Four mutually exclusive groups were created, using the presence or absence of COVID-19-related stress and lack of exercise habits as risk factors for poor OHRQoL (no COVID-19-related stress and no lack of exercise, COVID-19-related stress only, lack of exercise habits only, and both COVID-19-related stress and lack of exercise habits). Poisson regression with robust standard errors provided the prevalence ratio for poor OHRQoL. The presence of both COVID-19-related stress and lack of exercise habits (adjusted prevalence ratio: 2.20, 95% CI: 1.31- 3.69) was associated with poor OHRQoL. The results indicate that COVID-19-related stress and exercise habits should be considered when designing oral health and public health initiatives.

AIM: To examine the relationship between the number of present and functional teeth at baseline and future incidence of loss of independence. METHODS: Participants were community-dwelling older individuals who participated in a comprehensive geriatric health examination conducted in Kusatsu town, Japan, between 2009 and 2015. The primary endpoint was the incidence of loss of independence among participants, defined as the first certification of long-term care insurance in Japan. The numbers of present and functional teeth at baseline were determined via an oral examination. Demographics, clinical variables (e.g., history of chronic diseases and psychosocial factors), blood nutritional markers, physical functions, and perceived masticatory function were assessed. RESULTS: This study included 1121 individuals, and 205 individuals suffered from loss of independence during the follow-up period. Kaplan-Meier estimates of loss of independence for participants with smaller numbers of present and functional teeth were significantly greater than for those with larger numbers of teeth. Cox proportional hazard analyses indicated that a smaller number of present teeth was not a significant risk factor after adjusting for demographic characteristics. However, the number of functional teeth was a significant risk factor after the adjustment (hazard ratio: 1.975 [1.168-3.340]). Additionally, higher hazard ratios were observed in other adjusted models, but they were not statistically significant. CONCLUSIONS: The number of functional teeth may be more closely related to the future incidence of loss of independence than the number of present teeth. This novel finding suggests that prosthodontic rehabilitation for tooth loss possibly prevents the future incidence of this life-event. Geriatr Gerontol Int 2022; 22: 1032-1039.

Participation in sports groups has health benefits for older adults, such as preventing functional limitations and social isolation. Encouraging participation in sports groups may be an important means of health promotion in older adults. However, there is insufficient research on the determinants of new participation in sports groups to consider effective interventions to promote participation in these groups. We investigated this using data from a 1-year prospective study. Data were obtained from "The Otassha Study" that assessed a cohort of community-dwelling older adults living in an urban area of Japan. Of 769 older adults who participated in a baseline health survey in 2018, 557 participated in a follow-up survey in 2019. We excluded 184 individuals who already participated in sports groups at baseline and 36 with missing data. Participation in sports groups was defined as that occurring more than once a week. Logistic regression analysis was used to identify the determinants of new participation in sports groups, with sociodemographic factors, lifestyle habits, physical functions, cognitive functions, psychological factors, and social factors as independent variables. Forty-one (12.2%) individuals participated in sports groups at follow-up. In the multiple adjusted logistic regression model, new participation in sports groups was significantly associated with female sex (odds ratio [OR] = 5.57, 95% confidence interval [CI]: 1.61â19.26), engagement in regular exercise (OR = 2.23, 95%CI: 1.03â4.84), and having a large social network (OR = 1.12, 95%CI: 1.04â1.20). Physical functions were not associated with new participation. Determinants of new participation were lifestyle habits and social factors, rather than physical functions. Intervention through social networks may be effective in encouraging new participation in sports groups, which, in turn, may facilitate healthy aging.

Myxoma is the most common benign cardiac tumor. Absent pulmonary valves, often treated surgically in childhood, are associated with 3-6% of tetralogy of Fallot. It is unusual for absent pulmonary valves without other congenital heart diseases to be asymptomatic until adulthood. Here, we report the unique case of an 80-year-old female with right ventricular outflow tract myxoma and absent pulmonary valve that has, to our knowledge, never been reported. We successfully performed a simple mass resection and pulmonary valve implantation.
