End Point

<b><i>Introduction:</i></b> In patients with atrial fibrillation (AF) at risk for stroke, dabigatran 150 mg twice a day (DE150) is superior to warfarin for stroke prevention. However, there is paucity of data with respect to bleeding risk at this dose in elderly patients (≥75 years). We aimed to evaluate the safety of DE150 in comparison to warfarin in a real-world population with AF and low bleeding risk (HAS-BLED score ≤2). <b><i>Methods:</i></b> In this prospective observational study, 754 consecutive patients with AF and HAS-BLED score ≤2 were included. We compared outcome of elderly patients (age ≥75 tears) to younger patients (age &#x3c;75 years). The primary end point was the combined incidence of all-cause mortality, stroke, systemic emboli, and major bleeding event during a mean follow-up of 1 year. <b><i>Results:</i></b> There were 230 (30%) elderly patients, 151 patients were treated with warfarin, and 79 were treated with DE150. Fifty-two patients experienced the primary endpoint during the 1-year follow-up. Among the elderly, at 1-year of follow-up, the cumulative event rate of the combined endpoint in the DE150 and warfarin was 8.9 and 15.9% respectively (<i>p</i> = 0.14). After adjustment for age and gender, patients who were treated with DE150 had a nonsignificant difference in the risk for the combined end point as patients treated with warfarin both among the elderly and among the younger population (HR 0.58, 95% C.I = 0.25–1.39 and HR = 1.12, 95% C.I 0.62–2.00, respectively [<i>p</i> for age-group-by-treatment interaction = 0.83). <b><i>Conclusions:</i></b> Our results suggest that Dabigatran 150 mg twice a day can be safely used among elderly AF patients with low bleeding risk.

The elderly comprise less than 13 percent of world population. Nonetheless, they represent nearly half of all hospitalized adults. Acute change in mental status from baseline is commonly seen among the elderly even when the main process does not involve the central nervous system. The term “geriatric syndrome” is used to capture those clinical conditions in older people that do not fit into discrete disease categories, including delirium, falls, frailty, dizziness, syncope, and urinary incontinence. Despite the growing number of elderly population, especially those who require hospitalization and the high burden of common infections accompanied by encephalopathy among them, there are several unresolved questions regarding the optimal management they deserve. The questions posed in this systematic review concern the need to rule out CNS infection in all elderly patients presented with fever and altered mental status in the routine management of febrile encephalopathy. In doing so, we sought to identify all potentially relevant articles using searches of web-based databases with no language restriction. Finally, we reviewed 93 research articles that were relevant to each part of our study. No prospective study was found to address how should AFE in the aged be optimally managed.

BACKGROUND High blood pressure is one of the most important cardiovascular risk factor and its incidence is continuously increasing: on 2025 1/3 of adult world population will suffer of it. Moreover, the therapy of elderly hypertension sufferer patient is still growing up in importance for the continuous increase of world population average life. With ageing, the cardiovascular system suffers neurohormonal and haemodinamic modifications which determine the onset of isolate systolic hypertension, which is characteristic of the elderly. This pathology results linked to a higher cardiovascular risk. AIM OF THE STUDY This review aims to analyze and evaluate present and future therapeutic opportunities about anti-hypertensive therapy in elderly people. DISCUSSION AND CONCLUSIONS Also in elderly people systolic blood pressure values must be lower than 150 mmHg, but it’s also important to maintain diastolic pressure not under 70 mmHg, to avoid phenomenons of cerebral and coronary hypo-perfusion (J curve). The benefits of an effective anti-hypertensive therapy are achieved thanks to both blood pressure lowering “per se” and to the decrease of cardiovascular mortality and morbility. Blood pressure control in the elderly is a hard challenge for the low compliance to the therapy, for the importance of the comorbidity and for the supplementary risk factors. ESH-ESC 2007 guidelines recommend for elderly highblood pressure sufferer patient the use first of all of calcium-antagonists and thiazides diuretics, and for second line ACE-inhibitors, ARB and beta-blockers. In several patients combinations of two or more drugs are necessary to obtain pressure control.

The Impact

Anemia is a global health problem with an extremely high prevalence and occurring in nearly 25% of the world population, particularly in the elderly group. Currently Indonesia is facing a rapid growth of the elderly population, with around 21 million elderly (8.2% of the total population), that is projected to increase to 33.7 million (11.8%) in the year 2025. Anemia in the elderly is frequently neglected, although the facts show that low hemoglobin concentration is an important marker of physiological decline and functional limitations. Although the factor of intrinsic aging may cause low hemoglobin concentration, anemia in the elderly is known to have a wide range w88ith regard to etiology, underlying disorders, and  possible mechanisms, such that it should be clinically followed up. Whatever its causes or underlying pathophysiological, anemia in the elderly has been proven to play a role in their morbidity and mortality, and may decrease their quality of life, that comprises all aspects of physical, mental, and social health, known as health-related quality of life (HRQoL). The impact of anemia on HRQoL has been studied in various populations, and most studies report the presence of an association between HRQoL and anemia in elderly individuals, which on the subscale level is particularly associated with physical health. Early diagnosis of anemia is important to prevent aggravation of the condition, to retard the progress of the disease, and to improve the health-related quality of life (HRQoL) of the patient. Prior to determining the treatment plan, the primary diagnosis and the comorbidities, especially treatable disorders, had better be identified first. The available data show that the overall prognosis will improve for anemia in patients with well-managed and corrected chronic disorders.

Alzheimer's disease and vascular dementia are important causes of cognitive decline in the elderly and senile. This problem is becoming increasingly important in connection with the general aging of the world population and an increase in the number of patients with concomitant pathology, among which arterial hypertension plays an important role. There are a number of studies proving the link between arterial hypertension in middle age and dementia in the elderly. It is hoped that the normalization of blood pressure among middle-aged people will reduce the incidence of cognitive dysfunction. It is also known that maintaining blood pressure at acceptable levels in elderly and old people can improve brain function and reduce the prevalence of dementia, but it is not entirely clear which blood pressure numbers are optimal.

Quality Life

Modern society in recent decades is facing a large increase in the share of people over 65 in the total population. The research shows that the trend of increasing the number of the elderly is such that it is estimated that the share of people aged 65 and over in the world population will increase significantly (by 56%), from 901 million (12.3%) in 2015 to 1.4 billion (16.5%) in 2030. Nursing homes for the accommodation and care of the elderly are safe places that provide the elderly with reduced physical and other abilities and a life worthy of a human being. A wide field of interest for the research is the perception and experience of home care users about what a quality life in this environment could represent. As part of the quality of life assessment, different domains are assessed, and a certain degree of subjective assessment is included in the choice of quality of life domains. Given the demographic changes that have led to an aging population, as well as longer life expectancy, new measures of social and health policy towards the elderly are increasingly aimed at raising the quality of life of the elderly, while scientific research is increasingly focused on identifying factors that affect the quality of life of the elderly.

Current Design

The aging trend of the world population has increased the number of elderly people. Older people prefer to spend most of their time at home. The problem is that today's homes are often unsuitable for the elderly and the disabled. Thus, problems of the current design approaches, which are based on percentiles as well as the tendency to involve the elderly and disabled people in society, have put the concept of inclusive design into consideration. Application of new design approaches, such as inclusive design allows designers to design products and services to meet the needs of a larger group of users regardless of their age and ability. Given the rapid aging of the world population, more research is needed to design specific products and environments for elderly people. Keywords: Home design, Aging, Ergonomics, Adaptation

Determining the location of individuals within indoor locations can be useful in various scenarios including security, gaming and ambient assisted living for the elderly. Healthcare services globally are seeking to allow people to stay in their familiar home environments longer due to the multitude of benefits associated with living in non-clinical environments and technologies to determine an individual's movements are key to ensuring that home emergencies are detected through lack of movement can be responded to promptly. This paper proposes a device-free localisation (DFL) system which would enable the individual to proceed with normal daily activities without the concern of having to wear a traceable device. The principle behind this is that the human body absorbs/reflects the radio signal being transmitted from a transmitter to one or more receiving stations. The proposed system design procedure facilitates the use of a minimum number of wireless nodes with the help of a principle component analysis (PCA) based intelligent signal processing technique. Results demonstrate that human detection and tracking are possible to within 1m resolution with a minimal hardware infrastructure.
