Use of health care services according to functional performance in community-dwelling older adults in Spain. An approach using GAMLSS models.

Functional performance in older adults is a predictor of survival and other health outcomes and its measurement is highly recommended in primary care settings. Functional performance and frailty are closely related concepts, and frailty status is associated with the use of health care services. However, there is insufficient evidence on the utilization of services profile according to the functional performance of older adults. The aim of this study was to assess the relationship between functional performance and the use of a wide range of health services in community-dwelling older adults. Generalized additive models for location, scale and shape were used to study these complex data of services utilization, from primary to hospital care. A total of 749 participants from two Spanish regions were followed up for 2 years. Of those, 276 (37%) presented low functional performance and 473 (63%) normal performance according to the Timed Up and Go test. The results showed that even after adjusting for burden of comorbidity and polypharmacy, participants with low functional performance used primary and secondary care health services more intensively, visited emergency rooms more often, and were hospitalized more frequently and for longer periods of time. A negative binomial distribution and a variant thereof were found to be the best models to describe health service utilization data. In conclusion, functionality should be considered as an important health indicator for tailoring the provision of health services for older adults.

Relevance of well-being, resilience, and health-related quality of life to mental health profiles of European adolescents: results from a cross-sectional analysis of the school-based multinational UPRIGHT project.

PURPOSE: The existing evidence suggests that a complete evaluation of mental health should incorporate both psychopathology and mental well-being indicators. However, few studies categorize European adolescents into subgroups based on such complete mental health data. This study used the data on mental well-being and symptoms of mental and behavioral disorders to explore the mental health profiles of adolescents in Europe. METHODS: Data collected from adolescents (N = 3767; mean age 12.4 [SD = 0.9]) from five European countries supplied the information on their mental well-being (personal resilience, school resilience, quality of life, and mental well-being) and mental and behavioral disorder symptoms (anxiety, depression, stress, bullying, cyber-bullying, and use of tobacco, alcohol, or cannabis). Multiple correspondence analysis and cluster analysis were combined to classify the youths into mental health profiles. RESULTS: Adolescents were categorized into three mental health profiles. The "poor mental health" profile (6%) was characterized by low levels of well-being and moderate symptoms of mental disorders. The "good mental health" profile group (26%) showed high well-being and few symptoms of mental disorders, and the "intermediate mental health" profile (68%) was characterized by average well-being and mild-to-moderate symptoms of mental disorders. Groups with higher levels of well-being and fewer symptoms of mental disorders showed lower rates of behavioral problems. Mental well-being indicators strongly contributed to this classification. CONCLUSION: Adolescents with the "intermediate" or "poor" mental health profiles may benefit from interventions to improve mental health. Implications for school-based interventions are discussed.

Multimorbidity and functional status in older people: a cluster analysis.

PURPOSE: Multimorbidity and frailty are complex conditions often present in older people. The aim of this study was to identify clusters of chronic diseases in robust and frail individuals and compare sociodemographic and health characteristics between these clusters. METHODS: This cross-sectional study used information from electronic health records and a baseline assessment, which included the Timed Up and Go test of physical performance as a measure of frailty. Multiple correspondence and cluster analyses were performed to identify groups. RESULTS: A total of 813 individuals (55.1% women; mean age 77.4 years, SD = 5.0) were studied. Frail individuals (n = 244) were older and had a poorer health status than robust individuals (n = 569). Three clusters were identified among the robust (RC1, n = 348; RC2, n = 139 and RC3, n = 82) and four among the frail individuals (FC1, n = 164; FC2, n = 23; FC3, n = 44 and FC4, n = 13). The RC1 and FC1 had a better health status (specifically, less polypharmacy, lower chronic disease burden and better self-perceived health) than RC2-RC3 and FC2-FC3-FC4, respectively. Diseases associated with mobility limitation and limb pain were more common in RC2 and FC2 than in the other clusters. Cardiovascular diseases and risk factors were more prevalent in RC3 and FC3. Among the frail a new cluster emerged, FC4, containing individuals with higher rates of cognitive and eye problems and a clearly poor health status. CONCLUSION: This exploratory study may provide relevant information for the clinical management of older patients with multimorbidity, even though the chronic disease clusters identified were similar in robust and frail individuals.

Description of frail older people profiles according to four screening tools applied in primary care settings: a cross sectional analysis.

BACKGROUND: Regarding the health care of older populations, WHO recommends shifting from disease-driven attention models towards a personalized, integrated and continuous care aimed to the maintenance and enhancement of functional capacities. Impairments in the construct of functional intrinsic capacity have been understood as the condition of frailty or vulnerability. No consensus has been yet reached regarding which tools are the most suitable for screening this kind of patients in primary care settings. Tools based on the measurement of functional performance such as Timed up and go test (TUG), Short Physical Performance battery (SPPB), self-completed questionnaires like Tilburg Frailty Indicator (TFI) and clinical judgement, as the Gerontopole Frailty Scale (GFS) may be adequate. The objective of this work is to describe and compare characteristics of community-dwelling individuals identified as vulnerable or frail by four tools applied in primary care settings. METHODS: Cross sectional analysis developed in primary care services in two regions of Spain. Community-dwelling independent individuals aged 70 or more willing to participate were recruited and data was collected via face-to-face interviews. Frailty was assessed by TUG, SPPB, TFI and GFST. Also socio-demographic characteristics, lifestyle habits and health status data (comorbidities, polypharmacy, self-perceived health), were collected. Multiple correspondence analysis (MCA) and cluster analysis were used to identify groups of individuals with similar characteristics. RESULTS: Eight hundred sixty-five individuals were recruited, 53% women, with a mean age of 78 years. Four clusters of participants emerge. Cluster 1 (N = 263) contained patients categorized as robust by most of the studied tools, whereas clusters 2 (N = 199), 3 (N = 183) and 4 (N = 220) grouped patients classified as frail or vulnerable by at least one of the tools. Significant differences were found between clusters. CONCLUSIONS: The assessed tools identify different profiles of patients according to their theoretical construct of frailty. There is a group of patients that are identified by TUG and SPPB but not by GFS or TFI. These tools may be useful in primary care settings for the implementation of a function- driven clinical care of older patients.

Dietary Patterns and Their Relationship with Frailty in Functionally Independent Older Adults.

The impact of dietary patterns rather than single foods or nutrients on health outcomes is increasingly recognized. This cross-sectional study examines the dietary patterns of 527 non-institutionalized functionally independent older people aged ≥70 years from Gipuzkoa (Spain). Sociodemographic characteristics, health status, anthropometric measures and dietary data are collected. Multiple correspondence analysis (MCA) and cluster analysis are performed to identify dietary patterns and groups of individuals. Frequency of selected food items and compliance with food recommendations are included in the MCA. A high proportion of the sample population are overweight or obese, whereas only 3.3% are at risk of malnutrition (determined with the Mini Nutritional Assessment). Frail individuals (n = 130), measured with the Timed-Up and Go test are older, have a lower educational level, are more obese, present a poorer health status (more depressive symptoms, polypharmacy and falls, among others) and worse compliance with food recommendations than robust individuals (n = 392). Three groups of individuals are identified: cluster one (n = 285), cluster two (n = 194) and cluster three (n = 48). A gradient of increasing frailty and poorer health status is observed from cluster one to cluster three. The latter also shows the poorest dietary pattern, regarding dietary recommendations. The use of an easy-to-use tool to assess diet allows detection of differences among the three clusters. There is a need to increase awareness on the implementation of nutritional screening and a subsequent dietary assessment in primary care settings to provide nutritional care to elder, and moreover, frail individuals.

Inflammaging and Frailty Status Do Not Result in an Increased Extracellular Vesicle Concentration in Circulation.

In the last decades extracellular vesicles (EVs) have emerged as key players for intercellular communication. In the case of inflammation, several studies have reported that EV levels are increased in circulation during inflammatory episodes. Based on this, we investigated whether aging results in elevated EV number, as a basal proinflammatory status termed "inflammaging" has been described in aged individuals. Moreover, we also hypothesized that frailty and dependence conditions of the elderly could affect EV concentration in plasma. Results showed that inflammaging, frailty or dependence status do not result in EV increase, at least in the total number of EVs in circulation. These results open a new perspective for investigating the role of EVs in human aging and in the inflammaging process.

Lack of association between polymorphic copies of endogenous Jaagsiekte sheep retrovirus (enJSRVs) and Ovine Pulmonary Adenocarcinoma.

Ovine Pulmonary Adenocarcinoma (OPA) is a retrovirus-induced lung tumor of sheep, goat and mouflon, and its etiologic agent, Jaagsiekte sheep retrovirus (JSRV) is the only virus known to cause a naturally occurred lung adenocarcinoma. The oncogenic JSRV has several endogenous counterparts termed enJSRVs, some of which have been shown to interfere with JSRV replication at early and late stages of the retroviral cycle inhibiting JSRV exit from the cell, and thus, protecting sheep against the infection. In this work, Latxa sheep breed animals were classified depending on the presence/absence of OPA-characteristic clinical lesions in the lung. Using a PCR genotyping method and a logistic regression-based association study, five polymorphic enJSRV copies were analyzed in 49 OPA positive sheep and 124 control individuals. Our results showed that the frequency of the provirus enJSRV-16 is much higher in Latxa sheep breed than in other breeds, suggesting a recent proliferation of this provirus in the studied breed. However, no polymorphic enJSRV was found to be statistically associated with the susceptibility/resistance to OPA development.
