Effectiveness of a randomized intervention by a geriatric team in frail hospital inpatients in non-geriatric settings: FRAILCLINIC project.

Background: Little research has been undertaken on the benefits of frailty management within different hospital settings. The objective of this study is to provide evidence on the viability and effectiveness of frailty management in non-geriatric hospital settings on mortality and functional decline after discharge.

Methods: Data from the FRAILCLINIC (NCT02643069) study were used.

Differential utility of various frailty diagnostic tools in non-geriatric hospital departments of several countries: A longitudinal study.

Background: There is limited knowledge on the performance of different frailty scales in clinical settings. We sought to evaluate in non-geriatric hospital departments the feasibility, agreement and predictive ability for adverse events after 1 year follow-up of several frailty assessment tools.

Methods: Longitudinal study with 667 older adults recruited from five hospitals in three different countries (Spain, Italy and United Kingdom).

[Impact of the elderly patient in the emergency department].

Introduction: The aging of the population, chronic diseases, and non-urgent visits to the Emergency departments (ED) are considered the reasons for the increase of the demand of care. The aim of this study is to analyse the impact of the older population in the ED, when compared to a younger population.

Material And Methods: An observational, descriptive and retrospective study including an analysis of the 92,627 patients that attended the ED in Hospitals from Health Area IV belonging to the Principality of Asturias Health Services during 2009.

Immunosenescence and inflammation characterize chronic heart failure patients with more advanced disease.

Background: Chronic heart failure (CHF) is characterized by an inflammatory status with high levels of cytokines such as IL-6. We hypothesized that patients with CHF may develop immunosenescence due to inflammation and that this may be associated with a worse stage of the disease.

Methods And Results: We compared the immunological features of 58 elderly CHF patients (ECHF), 40 young CHF patients (YCHF), 60 healthy elderly controls (HEC) and 40 healthy young controls (HYC).

Frequent participation in high volume exercise throughout life is associated with a more differentiated adaptive immune response.

Exercise induces changes in the immune system depending on its intensity and duration. For example, transient states of immunodepression can be induced after acute intense physical activity whereas beneficial anti-inflammatory effects of moderate chronic exercise on many diseases and longevity have been described. To study the impact of high volume exercise over a lifetime on aspects of immunity we compared immunological features of 27 young and 12 elderly athletes with 30 young and 26 elderly non-athletes stratified by their CMV serostatus.

[Delirium in nursing homes. Prevalence and risk factors].

Objectives: To study the prevalence of delirium in the residential environment and to analyse the associated clinical, functional and mental factors.

Material And Methods: A cross-sectional epidemic study was conducted on a population of elderly persons institutionalised in 2011 in 6 nursing homes in Asturias. Socio-demographic, clinical, functional (Barthel Index [BI]) and mental (Mini-Mental State Examination [MMSE]) variables were collected.

IL-15 preferentially enhances functional properties and antigen-specific responses of CD4+CD28(null) compared to CD4+CD28+ T cells.

One of the most prominent changes during T-cell aging in humans is the accumulation of CD28(null) T cells, mainly CD8+ and also CD4+ T cells. Enhancing the functional properties of these cells may be important as they provide an antigen-specific defense against chronic infections. Recent studies have shown that IL-15 does in fact play an appreciable role in CD4 memory T cells under physiological conditions.

Relationship between functional ability in older people, immune system status, and intensity of response to CMV.

Shorter survival in the elderly has been associated with deterioration of the immune system and also with functional disability. To analyze the relationship between functional and immune impairment in older individuals, we studied 100 elderly who lived in a nursing home, were age matched, and grouped according to their functional status. We characterized cell subpopulations by flow cytometry, quantified TREC by RT-PCR, and measured the T-cell proliferation and activation response (IFN-γ by ELISPOT, CD69) against anti-CD3 and CMV.

Mortality and functional evolution at one year after hospital admission due to heart failure (HF) in elderly patients.

The aim of this observational study was to describe the characteristics (including functional measures) of the elderly patients hospitalized in the acute geriatric unit (AGU) and diagnosed with HF as well as to determine the variables associated with mortality at one year after discharge. A prospective study including patients aged 70 and over hospitalized for acute decompensated HF was performed. The baseline measures were demographics, comorbidity, clinical, functional and cognitive status.

NKG2D expression in CD4+ T lymphocytes as a marker of senescence in the aged immune system.

Human aging is characterized by changes in the immune system which have a profound impact on the T-cell compartment. These changes are more frequently found in CD8+ T cells, and there are not well-defined markers of differentiation in the CD4+ subset. Typical features of cell immunosenescence are characteristics of pathologies in which the aberrant expression of NKG2D in CD4+ T cells has been described.

[Metabolic syndrome and aging].

In recent years, the current "obesity epidemic" and its correlate, metabolic syndrome, have been related not only to cardiovascular disease but also to the presence of multiple chronic diseases and even to the development of disability. Therefore, it has been hypothesized that this situation of risk and that of frailty, which has aroused such interest in geriatrics, could share common physiopathologic mechanisms. These mechanisms are reviewed in the present article.

[Strongyloides stercoralis infestation in an immunocompetent 82-year-old woman].

A laboratory finding of eosinophilia in patients with gastrointestinal symptoms should prompt the differential diagnosis of a parasitosis. The diagnosis is based on identification of larvae in three different stool samples. We report the case of an 82-year-old woman who was independent for instrumental and advanced activities of daily living and showed no risk factors for strongyloidiasis who was admitted to our service with diarrhoea and abdominal pain.

[Risk factors associated with functional impairment at discharge and at three months after discharge in elderly individuals hospitalized for heart failure].

Objective: To determine the characteristics of elderly persons hospitalized for congestive heart failure and identify the factors associated with functional impairment or death at discharge and 3 months later.

Material And Methods: We performed a prospective observational study that included 162 patients admitted to an Acute Geriatric Care Unit with a diagnosis of heart failure from February to July 2007. Socio-demographic, clinical, functional and cognitive factors were recorded during admission.
