Relationship between oxidative stress and cognitive impairment in the elderly of rural vs. urban communities

Psychological stress and environmental pollution are frequently associated to urban environment and oxidative stress (OxS). Likewise, OxS is a risk factor for cognitive impairment (CI) in the elderly. Therefore, we hypothesized that the prevalence of CI in subjects of the urban area could be higher than in those of the rural area, and linked to higher OxS. The aim of the study was to determine the relationship between OxS and CI in elderly individuals from rural and urban settings in Mexico. Plasmatic TBARS, plasma total antioxidant status, and the antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx) were measured in 104 urban and 85 rural elderly individuals. Cognitive functions were evaluated through the Mini Mental State Examination. We found a greater proportion of subjects with OxS and CI in urban than in rural areas (25% vs. 9%), with an odds ratio of 5.67 (CI95% 1.14-38.02, p < 0.05). Our findings suggest that the elderly in urban areas have more OxS and a higher risk of developing CI compared with elderly individuals in a rural environment.     

Long-term ischaemic and bleeding outcomes after primary percutaneous coronary intervention for ST-elevation myocardial infarction in the elderly

Background

The population is ageing rapidly and the proportion of patients aged ≥ 80 years undergoing primary percutaneous coronary intervention (PCI) is rising, but clinical trials have primarily been performed in younger patients.

Methods

Patients undergoing primary PCI between 2003 and 2008 were subdivided into 3 groups: < 60, 60-79, and ≥ 80 years. Endpoints at 3-year follow-up included all-cause mortality, recurrent myocardial infarction (reMI), stent thrombosis, target lesion revascularisation (TLR), bleeding (BARC bleeding ≥ 3), stroke, and major adverse cardiovascular events (MACE, a composite of cardiac mortality, reMI, stroke and TLR).

Results

2002 patients with ST-segment elevation myocardial infarction (STEMI) were included, 885 (44.2 %) aged < 60, 921 (46.0 %) 60–79, and 196 (9.7 %) ≥ 80 years. Comorbidities such as diabetes mellitus, prior stroke, malignant disease, anaemia, and chronic kidney disease were more prevalent in patients ≥ 80 years. The incidence of both ischaemic and bleeding events strongly increased with age. Age ≥ 80 years was an independent predictor of mortality (HR 2.56, 95 % CI1.69–3.87, p < 0.001), a borderline non-significant predictor of overall bleeding (HR 1.38, 95 %CI 0.95–2.00, p = 0.088), and a significant predictor of non-access site bleeding (HR 2.26, 95 %CI 1.46–3.51, p < 0.001).

Conclusion

Patients ≥ 80 years experienced high rates of ischaemic and bleeding complications; especially in this high-risk patient group individualised therapy is needed to optimise clinical outcomes.

Association between dental health behaviours, mental/physical function and self-feeding ability among the elderly: a cross-sectional survey

Objectives : The aim of this study was to determine the association between dental health behaviour, mental/physical function and self‐feeding ability among the elderly. Subjects : A total of 414 elderly dental patients aged 65 years and older participated in this study. Methods : A survey was carried out for three years and seven months starting in January 1998 at the Chubu National Hospital. The patients or their carers were examined/interviewed about the severity of senile dementia, dental health behaviour, ability to rinse their mouths, ability to manage dentures, and ability to sit at a table during meals. To assess the association with self‐feeding ability among the elderly, cut‐offs were given for these variables, and then the odds ratios were calculated. Results : The strongest association to self‐feeding ability was marked by inability to rinse their own mouth, followed by inability to manage dentures, inability to sit at a table during meals, severe senile dementia and less frequency of toothbrushing. Conclusion : Elderly who have lost the feeding ability often could not maintain their dental health by themselves. Carers must provide not only a feeding service with acknowledgement of aspiration but oral care to prevent dental disease and fatal pneumonia in the elderly.     

Tolerance of debility in elderly dependants by supporters at home: its significance for hospital practice.

Some 12% of all geriatric admissions to University College Hospital and Whittington Hospital are for patients whose relatives or friends can no longer cope with them at home. The person principally involved with home support was interviewed in 50 such cases. The causes of inability to cope were identified on a quantitative and qualitative basis. The supporters were asked to assess which of the problems identified would have to be alleviated to restore a tolerable situation at home; 46 (92%) were able to do so. Identification of the "alleviation factors" forms a therapeutic and prognostic guideline in this type of admission and may have far-reaching social and economic implications.     

Staff attitudes to oral health care. A comparative study of registered nurses,nursing assistants and home care aides

This study compares differences in attitude, of oral health care of nursing personnel working with dependent elderly and severely disabled patients. A questionnaire was administered to 398 personnel covering (1) personal oral health care habits. (2) experiences and attitudes in assisting oral care and (3) willingness to assist patients/residents with their daily oral hygiene. Three hundred and sixty - four persons answered the questionnaire, including 70 registered nurses, 148 nursing assistants and 146 home care aides. The study revealed that oral care assistance is viewed as more disagreeable than other nursing activities. Although registered nurses were found to have more positive attitudes toward oral care assistance than the other nursing groups, they were seldom invoked in the daily practice of oral hygiene care. The results indicate a gap between knowledge and practice in nursing personnel's attitudes toward oral health care of dependent elderly and severely disabled patients.     

First-time dental care and the most recent dental treatment in relation to utilisation of dental services among dentate elderly patients in Lithuania

Objectives: To describe the initial dental treatments of Lithuanian dentate elderly patients and the content of the most recent treatment in relation to their dentist‐visiting behaviour. Materials and methods: A cross‐sectional questionnaire study was carried out at two public dental offices in Kédainiai, Lithuania, among dentate patients aged 60+ years. A self‐administered questionnaire covered first‐time dental care, the most recent dental treatment, check‐up behaviour, interval since the most recent dental visit, and number of teeth. Age, gender and education served as background information. Statistical evaluation was by chi‐squared test, anova and logistic regression for odds ratio (OR). Results: In all, 174 dentate elderly responded, mean age being 69.2 (SD = 6.6) years. The mean age at the first visit was 16.3 years [95% confidence interval (CI) 14.9–17.6]. Regular dental check‐ups were reported by 30%, and 36% had visited a dentist within the past 12 months. As to the content of the most recent treatment, 78% of the elderly reported filling therapy, 50% endodontics, 48% tooth extraction, 21% radiography, 10% cleaning or scaling and 6% polishing of fillings. Those going for check‐ups were more likely to report diagnostic (OR 1.9; 95% CI 1.1–2.8; p = 0.01) and preventive (OR 4.8; 95% CI 2.5–9.0; p = 0.002) treatment when analysed by a logistic regression model, controlling for age, gender, education and number of teeth. Conclusions: Check‐up‐orientated utilisation of dental services should be encouraged among the Lithuanian elderly. Dentists and health officials should place greater emphasis on prevention.     

Effect of high-quality care on limb function recovery and quality of life after osteoporotic hip fracture surgery in the elderly

Objectives:To evaluate the effect of high-quality care on limb function recovery and quality of life (QOL) after osteoporotic hip fracture (OHF) surgery in the elderly.Methods:116 elderly patients with OHF enrolled in our hospital from January 2017 to December 2019 were assigned into observation group (high-quality care, n=58) and control group (routine care, n=58). After one month of intervention, Harris Hip Score (HHS) and Barthel Index (BI) were used to evaluating limb function and self-care ability, pain intensity numerical rating scale (PINRS) for pain assessment, self-rating anxiety scale (SAS), and self-rating depression scale (SDS) for emotion assessment. Besides, postsurgical complications, QOL and patient satisfaction were examined.Results:HHS and BI were higher in observation group (P<0.05); PINRS, SAS and SDS were lower in observation group (P<0.05); incidence of postsurgical complications in the observation group was significantly lower than that in the control group (P<0.05); QOL and patient satisfaction in the observation group were higher than those in the control group (P<0.05).Conclusion:High-quality care promotes the recovery of limb function, the QOL and the satisfaction of elderly patients.     

Final benefit of primary percutaneous coronary intervention for ST-elevation myocardial infarction in older patients: long-term results of a randomised trial

BackgroundAlthough the short-term benefit of primary percutaneous coronary intervention (PCI) in elderly patients with ST-elevation myocardial infarction (STEMI) has been demonstrated, the final long-term survival benefit is as yet unknown.AimTo assess the final survival benefit of primary PCI as compared to thrombolytic therapy in patients over 75 years of age.MethodsPatients > 75 years with STEMI were randomised to either primary PCI or thrombolysis. Long-term data on survival were available for all patients.ResultsA total of 46 patients were randomised to primary PCI, 41 to thrombolysis. There were no significant differences in baseline variables. After a maximum of 20 years’ follow-up, all patients had passed away. The patients randomised to thrombolysis died after a mean follow-up duration of 5.2 years (SD 4.9) compared to 6.7 years (SD 4.8) in patients randomised to primary PCI (p = 0.15). Thus, the mean final survival benefit of primary PCI was 1.5 years.ConclusionThe final survival benefit of primary PCI as compared to thrombolysis in elderly patients with STEMI is 1.5 years and their life expectancy increases by 28.8%.     

Screening for suicidal thoughts in primary care: the views of patients and general practitioners

Background It has been argued that primary care practitioners have an important part to play in the prevention of suicide. However, levels of assessment of risk of suicide among patients treated in this setting are generally low.Methods Cross-sectional survey of general practitioners (GPs) and people being treated in primary care who had signs of depression. The study combined open and closed questions on attitudes to screening or being screened for suicidal ideation.Results One hundred and one of 132 patients took part in the survey and 103 of 300 GPs completed a questionnaire. A majority of both GPs and patients stated that people should be screened for suicidal ideation. However, an important minority of patients and GPs stated that asking or being asked such questions made them feel uncomfortable. Less than half of GPs had received formal training on the assessment of suicide risk. GPs told the researchers that barriers to screening included time pressures, culture and language, and concerns about the impact that screening could have on people's mental health. One-quarter of GPs and one-fifth of patients supported the notion that screening for suicidal ideation could induce a person to have thoughts of self-harm.Conclusions GPs and family doctors should screen for suicidal risk among depressed patients and should receive training on how to do this as part of their general training in the assessment and management of mental disorders. Research should be conducted to examine what, if any, effect screening for suicidal ideation has on mental health.     

Satellite-based monitoring of tropical seagrass vegetation: current techniques and future developments

Decline of seagrasses has been documented in many parts of the world. Reduction in water clarity, through increased turbidity and increased nutrient concentrations, is considered to be the primary cause of seagrass loss. Recent studies have indicated the need for new methods that will enable early detection of decline in seagrass extent and productivity, over large areas. In this review of current literature on coastal remote sensing, we examine the ability of remote sensing to serve as an information provider for seagrass monitoring. Remote sensing offers the potential to map the extent of seagrass cover and monitor changes in these with high accuracy for shallow waters. The accuracy of mapping seagrasses in deeper waters is unclear. Recent advances in sensor technology and radiometric transfer modelling have resulted in the ability to map suspended sediment, sea surface temperature and below-surface irradiance. It is therefore potentially possible to monitor the factors that cause the decline in seagrass status. When the latest products in remote sensing are linked to seagrass production models, it may serve as an early-warning system for seagrass decline and ultimately allow a better management of these susceptible ecosystems.     

Development of oral home telecare programme for the home-dwelling elderly: a pilot study

Objectives: The aim of the pilot study was to develop and evaluate a telecare programme for home‐dwelling elderly to provide education on oral and general health care. Design: A field trial with a computer system linking a university with a structured network. Subjects: A group of home‐dwelling elderly males with a mean age of 73.3 years. Methods: Qualitative assessment following videophone interviews with clients and their families. Results: Clients and families were able to gain a better understanding and knowledge of oral health care particularly the skills required to perform new oral care procedures. Conclusions: Preventive oral homecare via videophone offers the potential for providing a long‐term structure for maintaining oral health particularly with limited social resources.     

The health and cost effects of substituting home care for inpatient acute care: a review of the evidence

BACKGROUND: There is much interest in reducing hospital stays by providing some health care services in patients'' homes. The authors review the evidence regarding the effects of this acute care at home (acute home care) on the health of patients and caregivers and on the social costs (public and private costs) of managing the patients'' health conditions. METHODS: MEDLINE and HEALTHSTAR databases were searched for articles using the key term "home care." Bibliographies of articles read were checked for additional references. Fourteen studies met the selection criteria (publication between 1975 and early 1998, evaluation of an acute home care program for adults, and use of a control group to evaluate the program). Of the 14, only 4 also satisfied 6 internal validity criteria (patients were eligible for home care, comparable patients in home care group and hospital care group, adequate patient sample size, appropriate analytical techniques, appropriate health measures and appropriate costing methods). RESULTS: The 4 studies with internal validity evaluated home care for 5 specific health conditions (hip fracture, hip replacement, chronic obstructive pulmonary disease [COPD], hysterectomy and knee replacement); 2 of the studies also evaluated home care for various medical and surgical conditions combined. Compared with hospital care, home care had no notable effects on patients'' or caregivers'' health. Social costs were not reported for hip fracture. They were unaffected for hip and knee replacement, and higher for COPD and hysterectomy; in the 2 studies of various conditions combined, social costs were higher in one and lower in the other. Effects on health system costs were mixed, with overall cost savings for hip fracture and higher costs for hip and knee replacement. INTERPRETATION: The limited existing evidence indicates that, compared with hospital care, acute home care produces no notable difference in health outcomes. The effects on social and health system costs appear to vary with condition. More well-designed evaluations are needed to determine the appropriate use of acute home care.     

Health care professionals' perspectives on oral care for long-term care residents: nursing staff, speech-language pathologists and dental hygienists

doi: 10.1111/j.1741‐2358.2011.00513.x Health care professionals’ perspectives on oral care for long‐term care residents: Nursing staff, speech–language pathologists and dental hygienists Background: Oral health has been identified as a key factor in general health and systemic disease in long‐term care populations. To optimise oral health of this population, it is important to understand the oral care perspectives held by health care professionals involved in oral care provision. Objectives: To explore perspectives regarding oral care held by nursing staff, speech–language pathologists (SLPs) and dental hygienists (DHs) in long‐term care institutions and to understand how their perspectives impact activities and processes involved in the delivery of oral care. Methods: A focus group methodology was utilised. Separate focus groups for each targeted profession were held. Transcribed data were analysed using constant comparative analysis. Results: Daily oral health maintenance and monitoring was considered a role of nursing staff. SLPs and DHs have roles focusing on advocacy, education and supplemental care. Social factors motivate nursing staff to provide oral care, whereas factors related to the general health consequences of poor oral health underlined the motivations of SLPs and DHs. Conclusions: Education and training initiatives incorporating social aspects of oral health may be more effective for motivating nursing staff than approaches emphasising physical risk factors. Organisations can foster environments that support collaboration and communication amongst the members of multidisciplinary teams in order to promote oral health as a priority.     

Myth of independence: caring for house and residential facilities with care for the elderly

The innovations in the field of housing and care for elderly people often emphasize the concept of independence. Older people in these days are expected to competently and smoothly manage their own lives in a housing and care environment, that encourages self-help and selfsufficiency. Architects, care managers and politicians often are optimistic on the translation of independence into every-day practice of housing and care arrangements. By means of participating observations and interviews we explored how this translation is realised in an innovative project of 'lifetime' housing. Our results point out that strong and unexpected social factors develop in the use of space and caregiving that hinder personal fullfillment of autonomy. These problems were especially seen when every-day dependency failed to be noticed because of a too strongly emphasized autonomy.
