Marine-Derived Components: Can They Be a Potential Therapeutic Approach to Parkinson's Disease?

The increase in the life expectancy average has led to a growing elderly population, thus leading to a prevalence of neurodegenerative disorders, such as Parkinson's disease (PD). PD is the second most common neurodegenerative disorder and is characterized by a progressive degeneration of the dopaminergic neurons in the substantia nigra pars compacta (SNpc). The marine environment has proven to be a source of unique and diverse chemical structures with great therapeutic potential to be used in the treatment of several pathologies, including neurodegenerative impairments. This review is focused on compounds isolated from marine organisms with neuroprotective activities on in vitro and in vivo models based on their chemical structures, taxonomy, neuroprotective effects, and their possible mechanism of action in PD. About 60 compounds isolated from marine bacteria, fungi, mollusk, sea cucumber, seaweed, soft coral, sponge, and starfish with neuroprotective potential on PD therapy are reported. Peptides, alkaloids, quinones, terpenes, polysaccharides, polyphenols, lipids, pigments, and mycotoxins were isolated from those marine organisms. They can act in several PD hallmarks, reducing oxidative stress, preventing mitochondrial dysfunction, α-synuclein aggregation, and blocking inflammatory pathways through the inhibition translocation of NF-kB factor, reduction of human tumor necrosis factor α (TNF-α), and interleukin-6 (IL-6). This review gathers the marine natural products that have shown pharmacological activities acting on targets belonging to different intracellular signaling pathways related to PD development, which should be considered for future pre-clinical studies.

Caught in the middle: a thematic analysis of the experiences of Korean-Canadian caregiver-employees in the greater Toronto and Hamilton area.

BACKGROUND: The objective of this study was to investigate the experiences of caregiver-employees (CEs) from the Korean-Canadian community in the Greater Toronto and Hamilton Area. METHODS: Nine participants were recruited and invited to partake in data collection, which consisted of the completion of a sociodemographic questionnaire as well as a qualitative, semi-structured interview. The interview transcripts were thematically analyzed. RESULT: The thematic analysis revealed four primary themes, each of which had three sub-themes. The four primary themes are:: (i) tensions, (ii) adaptations to the dual role of being a CE, (iii) coping mechanisms, and (iv) desired changes to the status quo. CONCLUSION: The result of this study suggest that Korean-Canadian CEs, as a consequence of their position at the convergence of Korean and Western cultural values, would be best supported through the provision of culturally sensitive supports and greater workplace accommodation.

Environmental Challenges in the Home for Ageing Societies: a Comparison of Sweden and Japan.

Sweden and Japan are developed welfare countries facing serious societal and public health challenges due to demographic ageing. The objective of the present study was to provide a background to environmental challenges in the home, related to demographic ageing. Specific aims were to compare: 1) demography and household composition 2) physical housing stocks 3) indoor accidents and 4) housing adaptations between the two countries. Descriptive analyses were conducted using secondary data sources. Demographic ageing is projected to accelerate faster in Japan compared to Sweden, with overall lower fertility rates expected in Japan. In 2050, 39% of the Japanese population is projected to be aged 65 years or older, compared to 23% of the Swedish population. The Swedish ordinary housing stock was markedly older than the Japanese housing stock, with almost 80% of the dwellings built before 1980, while in Japan about 65% were built after 1980. High occurrences of fatal indoor accidents were noted in both countries, but for different reasons. In Sweden, falls was the dominant cause of fatal accidents among older people, while in Japan, in addition to falls, drowning and suffocation caused most of the fatal accidents. Housing adaptations were less frequent in Japan compared to Sweden, and the procedure for evaluating, granting and carrying out housing adaptations appeared to be more complicated in Japan. To decrease the occurrence of indoor accidents, identifying and removing "risk barriers" could be instrumental. In both countries, large-scale efforts are imperative to improve the housing situation for the ageing population.

Dental Care to Reduce Aspiration Pneumonia Recurrence: A Prospective Cohort Study.

BACKGROUND: Aspiration pneumonia has a high recurrence rate, and oral care by dentists has been found effective in preventing its onset; however, this has not been evaluated using prospective studies. Therefore, we conducted a prospective study to evaluate the effectiveness of professional oral care by dentists in reducing aspiration pneumonia recurrence in older adult patients. METHODS: In this prospective cohort study, we evaluated a dental oral care intervention, using a historical control group (control group). It was conducted at a single-centre regional core hospital in Japan that serves a large number of patients aged older than 80 years. Patients who were hospitalised for aspiration pneumonia were included in this study. During the study period (1 April 2021 to 31 March 2022), the clinical group received weekly professional cleaning by a dentist and the control group received standard oral care by a nurse as usual from 1 April 2020 to 31 March 2021. The dentist oral care group received weekly professional oral care from a dentist and was followed prospectively for 1 year. A Kaplan-Meier analysis was used to evaluate the timing of recurrent aspiration pneumonia or death. A Cox proportional hazards model was used to obtain a hazard ratio and determine the 95% confidence intervals. RESULTS: There were 91 participants in the clinical group and 94 in the control group. The mean age of participants was 85 years, and 75 (40.5%) were female. The recurrence rate was 27.5% in the clinical group and 44.7% in the control group (P = .005). Professional cleaning by a dentist reduced the risk of recurrence of aspiration pneumonia by approximately 50% (adjusted hazard ratio, 0.465; 95% confidence interval, 0.278-0.78). CONCLUSIONS: Professional cleaning by a dentist was associated with a lower rate of aspiration pneumonia recurrence than nurse-provided conventional oral care.

A preliminary survey of rheumatologists on the management of late-onset rheumatoid arthritis in Japan.

Objectives We investigated the current perspectives regarding the management of late-onset rheumatoid arthritis (LORA) among rheumatologists in clinical practice. Methods This study was performed in October 2021, and included 65 rheumatologists certified by the Japan College of Rheumatology, who were administered questionnaires (including multiple choice and descriptive formulae) regarding the management of LORA. We aggregated and analyzed the responses. Results All 65 rheumatologists responded to the survey; 47 (72%) answered that >50% of newly diagnosed patients were aged ≥65 years, 42 (65%) answered that achievement of remission or low disease activity was the treatment goal, and 40 (62%) considered patient safety to be the highest priority. Most rheumatologists are concerned about the management of conditions other than RA, such as comorbidities, financial constraints, and life circumstances that interfere with standard or recommended treatment implementation. Conclusion This preliminary survey highlighted various rheumatologists' perspectives regarding the management of LORA.

Medication overload: A closer look at polypharmacy and potentially inappropriate medications among older people in Taiwan and Japan.

BACKGROUND: Polypharmacy and potentially inappropriate medications (PIM) are widely recognized as vital quality indicators of pharmacotherapy in older adults. As Taiwan and Japan grapple with the ongoing challenges of population aging, obtaining an accurate understanding of the prevalence of these indicators is crucial for developing effective strategies to optimize pharmacotherapy in older populations. The present study aims to comprehensively evaluate the prevalence of polypharmacy and PIMs in Taiwan and two Japanese cohorts, shedding light on the similarities and differences in prescribing practices across these populations. METHODS: This study employed a cross-sectional design to investigate individuals aged ≥65 years in Taiwan, as well as two Japanese cohorts: Japan Cohort 1 (dispensing data from chain pharmacies; year 2014 and 2019) and Japan Cohort 2 (claims data; year 2017 and 2019). The prescription records of these participants were collected from the national claims database in Taiwan for the years 2014, 2017, and 2019. To identify polypharmacy and hyper-polypharmacy, the study defined the use of 5-9 and 10+ drugs, respectively. Furthermore, the study identified PIMs based on the STOPP-J criteria. Notably, the study further explored the most frequently used PIMs (by categories) in Taiwan. RESULTS: In the year 2019, the prevalence of polypharmacy exhibited similar rates in Taiwan (35.4%) and Japan Cohort 2 (33.1%), while surpassing that of Japan Cohort 1 (25.6%). Nonetheless, the incidence of PIMs in Taiwan was the highest (66.5%), exceeding those of the two Japanese cohorts (Cohort 1: 43.7% and Cohort 2: 40.2%) in the same year. Notably, the top three categories of commonly used PIMs in Taiwan comprised non-steroidal anti-inflammatory drugs (NSAIDs), antithrombotic drugs, and benzodiazepines. CONCLUSIONS: This study highlights the varying prevalence of polypharmacy and PIMs between Taiwan and Japan, but emphasizes the need for collaborative efforts towards optimizing pharmacotherapy in older adults.

Aetiology of chronic heart failure in patients from a super-aged society: the KUNIUMI registry chronic cohort.

AIMS: With the rapidly increasing ageing population, heart failure is an urgent challenge, particularly in developed countries. The study aimed to investigate the main aetiologies of chronic heart failure in a super-aged society. METHODS AND RESULTS: The KUNIUMI registry chronic cohort is a community-based, prospective, observational study of chronic heart failure in Awaji Island, Japan. Inhabitants of this island aged ≥65 years accounted for 36.3% of the population. In the present study, data from patients with symptomatic heart failure were extracted from the registry. A total of 1646 patients were enrolled from March 2019 to March 2021, accounting for ~1.3% of the inhabitants of Awaji Island. We analysed 852 patients with symptomatic heart failure. The mean age was high (78.7 ± 11.1 years), with 357 patients (41.9%) being female. The proportion of women increased significantly with advancing age and constituted more than half of the patients aged 85 years and older (P < 0.01). The prevalence of atrial fibrillation, and in particular long-standing persistent atrial fibrillation, increased at 70 years of age (P < 0.01). The proportion of patients with heart failure with preserved ejection fraction increased to ~60% when age was over 75 years. Although ischaemic heart disease accounted for 35.0% of chronic heart failure aetiologies, valvular heart disease was the most common cause of chronic heart failure (49.8%). The major types of valvular heart disease were mitral regurgitation and tricuspid regurgitation (27.2% and 21.7%, respectively), both of which increased significantly with age (P < 0.01). The incidence of aortic valve stenosis increased markedly over the age of 85 years (P < 0.01). Atrial functional mitral regurgitation increased with age and was the major cause of mitral regurgitation in patients aged >75 years. Patients with atrial functional mitral regurgitation had a higher prevalence of atrial fibrillation (especially long-standing persistent atrial fibrillation) and a larger left atrial volume index when compared with patients with other types of mitral regurgitation (P < 0.001, respectively). CONCLUSIONS: The KUNIUMI registry chronic cohort showed a change in heart failure aetiology to valvular heart disease in a super-aged society. Effective and comprehensive countermeasures are required to prepare for the rapid rise in heart failure incidence in a super-aged society.

Negative association between loneliness and healthy state among rural residents in Japan: a cross-sectional single region population-based survey.

Objective: Loneliness is an important health problem in rural areas of Japan because of its ageing and declining population. Therefore, we investigated the association between loneliness and health. Materials and Methods: Self-administered questionnaires were distributed to rural adult residents. The Japanese 3-item versions of the UCLA Loneliness Scale, self-rated health (SRH), and objective health status (whether the respondents had a physical and/or mental illness) were used. We defined a UCLA score of four points or more as loneliness, an SRH of four points or more as a subjective healthy state, and no physical or mental illness as an objective healthy state. The association was adjusted for sociodemographic data, lifestyle habits, and isolation risk using logistic regression analysis. Results: The five-year population decline rate in the target areas was 10.2 to 12.3%. Of the 2,700 participants, there were 1,211 male and 1,489 female respondents, with an average age of 65.4 years. Moreover, 358 (13.6%) were living alone, and 829 (31.5%) were living in couple-only households. Among the participants, 1,395 (53.2%) experienced loneliness, 1,751 (65.7%) had good self-rated health, and 1,587 (60.8%) had objective health status. Loneliness was negatively associated with good SRH (OR=0.56, CI=0.45-0.70) and objective health status (OR=0.57, CI=0.46-0.71) after adjusting for sociodemographic data, lifestyle habits, and the risk of isolation. Statistically significant confounding factors for subjective and/or objective health status were employment, not smoking, obesity, exercise, having a family doctor, having an above-average number of teeth, and the ability to leave home. Conclusion: In an ageing and declining population, loneliness is an independent factor affecting the health status of rural residents and is not limited to older adults. Therefore, measures to reduce it are needed.

Multisite Lifestyle for Older People after the Fukushima Nuclear Disaster.

After the Fukushima nuclear power plant disaster in 2011, the Japanese government implemented a return policy, lifting most evacuation orders in former evacuation areas. Consequently, the return of residents is currently underway. However, it has become common for a large number of residents to carry out multisite living, a lifestyle involving returning to their hometown while maintaining their house at the evacuation site, or living at more than two sites. This report focuses on one aspect of the secondary effects of the nuclear incident, which forced affected residents to adopt a multisite lifestyle. Disasters always have a strong impact, via displacement, on those who are socially vulnerable, such as older people in an ageing society. They need intense support to resume their daily life as it was before the incident. For this report, we interviewed an elderly lady in her 90s, who is executing "multisite living" at evacuation sites, in order to obtain reassurance from neighbours and the local community. Our findings may provide valuable suggestions on how older people can restart their lives with the local community in an ageing society after disasters, which could apply to any kind of disaster preparedness.

Designing Robots for Elderly from the Perspective of Potential End-Users: A Sociological Approach.

The proposed research aims to investigate the problem of age-friendly robot designing from the perspective of the potential end-users. The initial objectives addressed three main issues: how the elderly envision robots and their knowledge on technological development; age-friendly robot design; the elderly's involvement in the robot design process. The empirical material analyzed are the results of in-depth interviews with people aged 70+. A sociological approach is proposed, based mainly on criticism of writing and the analytical and synthetic method. The theoretical framework is the perspective of an ageing society and technogerontology. The sociological approach enables better understanding of the sensitive problems of age-friendly robot designing from the individual point of view. It is concluded with a conceptual discussion on designing robots for the elderly. In particular, it is revealed how these issues could help in shaping social consensus about age-friendly technologies.

Long-term exposure to moderate fine particulate matter concentrations and cause-specific mortality in an ageing society.

BACKGROUND: Long-term exposure to particulate matter <2.5 µm in size (PM2.5) is considered a risk factor for premature death. However, only a few studies have been conducted in areas with moderate PM2.5 concentrations. Moreover, an ageing society may be more susceptible to environmental exposure and future burden of mortality due to PM2.5. METHODS: This study estimates hazard ratios (HRs) for all-cause and cause-specific mortality from long-term exposure to moderate PM2.5 concentrations in the elderly populations of seven cities in South Korea. We also projected nationwide elderly mortality caused by long-term exposure to PM2.5, accounting for population ageing until 2045. Mortality in 1 720 230 elderly adults aged ≥65 years in 2008 was monitored across 2009-16 and linked to modelled PM2.5 concentrations. RESULTS: A total of 421 100 deaths occurred in 2009-16, and the mean of annual PM2.5 concentration ranged between 21.1 and 31.9 µg/m3 in most regions. The overall HR for a 10 µg/m3 increase in a 36-month PM2.5 moving average was 1.024 (95% confidence intervals: 1.009, 1.039). We estimated that 11 833 all-cause nationwide elderly deaths were attributable to PM2.5 exposure. Annual death tolls may increase to 17 948 by 2045. However, if PM2.5 is reduced to 5 µg/m3 by 2045, the tolls may show a lower increase to 3646. CONCLUSIONS: Long-term exposure to moderately high levels of PM2.5 was associated with increased mortality risk among the elderly. Thus, PM2.5 reduction in response to the projected ageing-associated mortality in South Korea is critical.

The Need for a Paradigm Shift in Approaching Ageing-Related Design Research and Practice.

Despite a rapidly ageing world population, ageism - particularly in its implicit form - is widespread in society. In this article, we propose that a paradigm shift is needed in how we approach ageing-related design research and practice in areas such as assistive technologies. We also put forward the idea of using the Healthy Ageing (HA) framework of the WHO as the basis for new lines actions that can be taken by design researchers and practitioners to address implicit ageism in society through their work.

COVID-19 Vaccine Literacy of Family Carers for Their Older Parents in Japan.

In super-ageing Japan, COVID-19 vaccinations were starting to reach older people as of June 2021, which raises the issue of vaccine literacy. This study focuses on family members who work and also care for their older parents, as they are at risk of COVID-19 and also risk transmitting COVID-19 to the parents they care for and potentially influencing their parents' vaccine uptake. Such family carers are central to the approach in Japan to achieving a sustainable and resilient society in response to ageing. Contrasting family carers' COVID-19 vaccine literacy with their overall health literacy provides insights into their preparedness for COVID-19 vaccinations. The purpose of this study is to understand how vaccine literacy, compared to health literacy, varies across family carers and the sources of information they use. Through a cross-sectional online survey, family carers' vaccine literacy, health literacy and their sources of information, including mass media, social media, health and care professionals, family, colleagues, friends, and others, were assessed. The participants' (n = 292) mean age was 53, with 44% women, and an average of 8.3 h per week caring for their parents. Notwithstanding the increased risks from COVID-19 with age, COVID-19 vaccine literacy relative to health literacy for older family carers is lower on average, higher with increased provision of care, and more variable, resulting in a substantial proportion of older family carers with relatively low vaccine literacy. At this stage of vaccine rollout in Japan, family carers' sources of information to inform COVID-19 vaccine literacy is distinct, including more national and local mass media versus less health and care professionals and informal networks, which indicates the importance of tailored health communication strategies to enhance vaccine literacy.

Exploring perceptions toward home-care robots for older people in Finland, Ireland, and Japan: A comparative questionnaire study.

PURPOSE: To clarify potential users' perceptions toward the development and social implementation of home-care robots in Japan, Ireland, and Finland. METHODS: Unsigned, self-administered questionnaires were distributed to adults aged 65 or older, family caregivers, and home-care/health and social care professionals (HSCPs). A total of 1004 responses were collected. RESULTS: In Japan, many people were already familiar with robots in their daily lives. The most notable finding about their perspectives on home-care robots was related to safety. Moreover, 93.7 % of the Japanese respondents said, "If the user cannot decide whether to use a home-care robot, family members who know the user well should decide," followed by 76.4 % in Ireland and 83.1 % in Finland (p < .001). In Ireland, 81.8 % of the respondents said, "I want to help other people and society by participating in the research and development of home-care robots" (Japan: 69.9 %; Finland: 67.5 %) (p = .006). In Finland, many people had a negative impression of robots compared to the other two countries. Finland had the highest percentage (75.4 %) of respondents who said, "Health care professionals should be allowed to use secondary information collected by a home-care robot" (Japan and Ireland: 64 %) (p = .024). Moreover, Ireland and Finland emphasized the need to guarantee the entitlement to receive human care. CONCLUSIONS: Devising optimal strategies for the development and social implementation of home-care robots by incorporating various perspectives while valuing human dignity will require examination of each country's characteristics with respect to history, culture, policies, and values related to robots.

An analysis of the costs of treating aged patients in a large clinical hospital in Poland under the pressure of recent demographic trends.

INTRODUCTION: The aging of modern societies increases the general healthcare burden due to the growing demand for inpatient services, which lack adequate financing. MATERIAL AND METHODS: Data concerning the costs of 312,250 hospitalizations at University Clinical Hospital in Wroclaw, Poland in the years 2012-2015 were analyzed according to the age of the patients: below 65 years and 65 years and older, with subgroups (65-74, 75-84 and 85 years and older). RESULTS: The mean length of stay (LOS) differed significantly for patients below 65 years and for patients 65 years old or older (3.5 vs. 4.7 person-days); over the 4 years covered by our data, these increased by 0.4 person-days, mostly among patients 85 years and older (by 0.7 person-days). The mean direct cost of hospitalization differed significantly for patients below 65 years and those 65 years or older (PLN 4,907.12 vs. PLN 6,357.15). The mean cost of laboratory tests and radiologic diagnostics was significantly higher among those in the 65+ group, and the difference had a rising trend. The differences between age groups in cost-related hospitalization characteristics and direct hospitalization costs that have been suggested by the medical literature have also been confirmed in Poland. CONCLUSIONS: The mean hospitalization costs of patients aged 65 years and older in Poland are higher than for younger patients due to longer LOS and more complex and expensive treatment, especially laboratory and radiologic diagnostics, which is increasingly common in the oldest age groups. This demands an urgent systemic solution, especially in terms of adjusted financing of elderly patients' hospital treatment.

Bergeyella zoohelcum isolated from oral cavities of therapy dogs.

Bergeyella zoohelcum causes rare but severe human clinical diseases, which mostly arise from animal bites. Notably, Bergeyella infections can also occur in older people after prolonged exposure to dogs or cats without biting. We detected B. zoohelcum in oral cavities of therapy dogs in close contact with older people residing in nursing homes. Twenty-two bacterial isolates were identified as B. zoohelcum by using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing. Our results showed that MALDI-TOF MS is an effective tool for rapid identification of rarely isolated, difficult-to-identify microorganisms, such as B. zoohelcum, derived from not only human clinical samples but also animal samples. To our knowledge, this is the first report on detection of B. zoohelcum from therapy dogs. We have provided information on dog-assisted therapy to improve the relationship between humans and animals in ageing societies, particularly for preventive healthcare of older people living in nursing care facilities.

Combined impact of future trends on healthcare utilisation of older people: A Delphi study.

PURPOSE: To explore the combined effect of trends in older people on their future healthcare utilisation. METHODS: A Delphi study consisting of two rounds was conducted. The heterogeneous expert panel (n = 16) in the field of elderly care rated the effect of combinations of trends in the Netherlands on the use of seven healthcare services: i.e. informal, home, general practitioner, acute, specialist, nursing home and mental health care. The percentage and direction of the overall consensus, for the different health services, and for three main trends were analysed. RESULTS: Experts reached consensus in 57 of 92 ratings (62%). Taking into account the interaction between trends, they expected an extra increase for informal, home, and general practitioner care, but no additional effect of interaction for specialist and acute care. Combinations that included trends leading to less support were expected to lead to an extra increase in utilisation. CONCLUSIONS: Experts expect that interaction between trends will lead to an extra increase in the use of general practitioner, home, and informal care. This increase is mainly the result of interaction with trends leading to less support for older persons. The present results show the need to take the effect of interaction into account when designing new health policy and in research on future healthcare utilisation.

Oral health for healthy longevity in an ageing society: maintaining momentum and moving forward.

The ageing of populations worldwide is rapidly accelerating. However, the global burden of oral disease remains a critical and often underestimated problem. As ageing progresses globally, oral health maintenance becomes a matter not only of public health, but also of human rights. Therefore, in low- and middle-income countries, policymakers are seeking to realize universal health coverage even as they struggle with severe resource limitations. To achieve and maintain global oral health, we propose an ongoing global monitoring cycle consisting of the following four steps: needs assessment, implementation of appropriate health care systems and provisions, reducing the global burden of oral disease, and working to achieve a healthy ageing society. Rather than a unidirectional information flow from high income to low- and middle-income countries, the proposed system would establish a multidirectional information-sharing cycle that would benefit all countries. To make this possible, however, we must develop a standardized set of core oral health indicators that all countries use, as well as a global repository for gathering, compiling, and sharing the data. This system would allow each country to move forward at its own pace and in locally-appropriate ways, making it more effective and efficient in the long run than the current pattern of setting unrealistic goals that all countries are expected to achieve by a certain point in time.

Improved Housing Accessibility for Older People in Sweden and Germany: Short Term Costs and Long-Term Gains.

The physical housing environment is important to facilitate activities of daily living (ADL) for older people. A hindering environment may lead to ADL dependence and thus increase the need for home services, which is individually restricting and a growing societal burden. This study presents simulations of policy changes with regard to housing accessibility that estimates the potential impact specifically on instrumental activities of daily living (I-ADL), usage of home services, and related costs. The models integrate empirical data to test the hypothesis that a policy providing funding to remove the five most severe environmental barriers in the homes of older people who are at risk of developing dependence in I-ADL, can maintain independence and reduce the need for home services. In addition to official statistics from state agencies in Sweden and Germany, we utilized published results from the ENABLE-AGE and other scientific studies to generate the simulations. The simulations predicted that new policies that remove potentially hindering housing features would improve I-ADL performance among older people and reduce the need for home services. Our findings suggest that a policy change can contribute to positive effects with regard to I-ADL independence among older people and to a reduction of societal burden.

Social implications and workforce issues in the oral health of an ageing population.

A functional and socially acceptable level of oral health is an integral part of healthy ageing! More teeth, more sophisticated dental technology and increasing co-morbidities of an ageing Australian society will have significant impacts on oral health professionals and their capacities to work within expanded teams of health, education and social organizations. Society is adapting its perspective on the social role of older citizens; replacing its perception of the elderly as an economic social burden, to one of senior citizens as being a respected and active source of social and economic benefit. Maintaining general and oral health for older Australians will bring into sharp focus the need for recognizing and managing not only the biological markers associated with ageing and frailty, but also the potential mediators on health outcomes associated with changing health and social behaviours. Increasing social capital of older Australians through national policy initiatives such as the Living Longer Living Better reforms, and greater involvement of allied health and carers' organizations in oral health education and health promotion will set a new scene for the roles of dental professionals. Issues of equity will drive the service delivery agenda, and a socio-cultural shift to 'consumer-directed' health outcomes will shape the range of services, quality of care and support required by an older Australian population. Formal education and training modules for aged care workers, allied health practitioners and geriatricians will develop. The challenge for the dental profession is the coordination and integration of these changes into new models of dental and general health care.
