Mobility limitations and cognitive deficits as predictors of institutionalization among community-dwelling older people.

2006

<i>Purpose:</i> Mobility limitations and cognitive disorders have often been observed as risks for institutionalization. However, their combined effects on risk of institutionalization among initially community-dwelling older people have been less well reported. <i>Design:</i> A prospective cohort study with 10-year surveillance on institutionalization. <i>Subjects:</i> Study population (n = 476) consisted of 75- and 80-year-old people who were community-dwelling, had not been diagnosed with dementia, and participated in tests on walking speed and cognitive capacity at a research centre. <i>Measures:</i> Cognitive capacity was measured with th…

Leisure-time physical activity from mid- to late life, body mass index, and risk of dementia

2013

Abstract Background Physical activity may be beneficial for cognition, but the effect may vary depending on personal characteristics. Methods We investigated the associations between leisure-time physical activity (LTPA) from mid- to late life, the risk of dementia, and the role of body mass index, sex, and APOE in the CAIDE study during 28-year follow-up. Cognitive function of a random subsample was assessed at a mean age of 78.8 years (n = 1511), and dementia/Alzheimer's disease (AD) diagnoses were identified from national registers for the entire target population (n = 3559). Results Moderate (hazard ratio [HR], 1.46; 95% confidence interval [CI], 1.08–1.99) and low levels of midlife LTP…

Do negative life events promote gerotranscendence in the second half of life?

2014

Objectives: Gerotranscendence has been defined as a developmental shift in meta-perspective from a materialistic and pragmatic view to a more cosmic and transcendent view. Although gerotranscendence has been argued to increase with age and life experiences, the results have been mixed and based on cross-sectional studies. We use a longitudinal setting to investigate the role of negative life events, age, and gender on change in one dimension of gerotranscendence, cosmic transcendence. Method: 1569 individuals (ages 58-89) answered a questionnaire on cosmic transcendence in two cycles of the Longitudinal Aging Study Amsterdam in 1995-1996 (time 1) and 1998-1999 (time 2). Controlling for educ…

Changes in Frailty Status and Risk of Depression: Results From the Progetto Veneto Anziani Longitudinal Study.

2017

Objective To evaluate whether prefrailty was associated with the risk of developing depression and if longitudinal changes in frailty status corresponded to changes in incident depression during follow up. Methods A population-based, prospective cohort study was conducted for 4.4 years in two separate geographic areas near the city of Padua in the Veneto Region of Northern Italy. In 891 nondepressed, nonfrail, community-dwelling Italian subjects aged ≥ 65 (46.6% men) belonging to the Progetto Veneto Anziani study, depression was defined according to the Geriatric Depression Scale and was confirmed by geriatricians skilled in psychogeriatric medicine. Prefrailty was defined by the presence o…

Characterizing land condition variability in Ferlo, Senegal (2001–2009) using multi-temporal 1-km Apparent Green Cover (AGC) SPOT Vegetation data

2011

Abstract The ecosystem state or ‘land condition’ can be characterized by a set of attributes, which show variations at different temporal scales. A multi-resolution analysis (MRA) based on the wavelet transform (WT) has been implemented to examine the land condition of a dryland region in Ferlo (Senegal) over the period 2001–2009. This methodology has proven to be useful for smoothing time series while considering those temporal resolutions that incorporate information about the vegetation dynamics. For this purpose, time series of the 1-km Apparent Green Cover (AGC) from the 10-day composites SPOT Vegetation (VGT) data are analyzed. Two relevant outputs from the MRA, A 1 (de-noised) and th…

Irrationale Einstellungen und soziale Belastung bei Patienten in ambulanter Verhaltenstherapie: Verlauf, prognostische und mediierende Einflüsse auf …

2002

Fragestellung: Bisherige Studien legen nahe, dass sozialer Stress und kognitive Dysfunktion zur Entwicklung psychischer Storungen beitragen konnen. Kaum untersucht wurde, inwieweit beide Faktoren die Heilungschance bei psychotherapeutischer Behandlung beeinflussen und mit dem Behandlungserfolg kovariieren. Ziel der Studie war, die 1. Veranderung irrationaler Einstellungen und der Wahrnehmung sozialer Belastung im Verlauf ambulanter Verhaltenstherapie sowie 2. ihre Rolle als Pradiktoren und 3. als Mediatoren des Behandlungsergebnisses bei Patienten mit heterogenen Diagnosen zu untersuchen. Methoden: Eine diagnostisch unausgelesene Stichprobe von 62 Patienten wurde zu Beginn und zum Abschluss…

A review of runoff generation and soil erosion across scales in semiarid south-eastern Spain

2011

Climate, lithology, soil and especially, intense land use/cover changes, make SE Spain very vulnerable to runoff generation and water erosion leading to loss of nutrients and organic matter and to infrequent but devastating floods, reservoir siltation and mass failures. This susceptibility has led to heavy economic investment and research efforts since the 1980s, making this region a worldwide reference for understanding the hydrology and geomorphology of semiarid ecosystems. Runoff and soil erosion have been intensively studied throughout the last decades in various natural ecosystems as well as in abandoned farmlands. Research has considered a wide range of methods and spatial and tempora…

The Primary Care Evaluation of Mental Disorders (PRIME-MD), German version: a comparison with the CIDI

2000

There is a need for the development and evaluation of diagnostic instruments suitable for daily use in primary care offices that can improve recognition rates of psychopathology. The objective of this study is the comparison of the German version of the Primary Care Evaluation of Mental Disorders (PRIME-MD), a short structured diagnostic instrument, with the Composite International Diagnostic Interview (CIDI) and to gather some information on the usefulness of the PRIME-MD. Seven hundred and four patients were assessed three times, once using the physician's clinical judgement, subsequently, administering the PRIME-MD, DSM-IV version and finally, with the CIDI. The CIDI was administered on …

Predicting event soil loss from bare plots at two Italian sites

2013

Abstract Including runoff in USLE-type empirical models is expected to improve plot soil loss prediction at the event temporal scale and literature yields encouraging signs of the possibility to simply estimate runoff at these spatial and temporal scales. The objective of this paper was to develop an estimating procedure of event soil loss from bare plots (length = 11–44 m, slope steepness = 14.9–16.0%) at two Italian sites, i.e. Masse, in Umbria, and Sparacia, in Sicily, having a similar sand content (5–7%) but different silt (33% at Sparacia, 59% at Masse) and clay (62% and 34%, respectively) contents. A test of alternative erosivity indices for the Masse station showed that the best perf…
