Standing up from a chair as a dynamic equilibrium task: a comparison between young and elderly subjects.
2000
The purpose of this study was to analyze and compare the features of center of mass (CoM) control along anterior/posterior axis in young and elderly subjects during sit-to-stand (STS). From a sitting position, seven healthy young subjects and seven healthy elderly subjects were asked to stand up from a chair under different experimental conditions (visual conditions: normal and blindfolded; speed: normal and as fast as possible). Analysis of results was based upon the concept of a “dynamic equilibrium area” (DEA), which in turn identified the dynamic limits of balance. The results showed that both the maximal CoM velocity in the horizontal axis and the CoM velocity at the instant of seat-of…
Changes in muscle morphology, electromyographic activity, and force production characteristics during progressive strength training in young and olde…
1998
Effects of a 10-week progressive strength training program composed of a mixture of exercises for increasing muscle mass, maximal peak force, and explosive strength (rapid force production) were examined in 8 young (YM) (29+/-5 yrs) and 10 old (OM) (61+/-4 yrs) men. Electromyographic activity, maximal bilateral isometric peak force, and maximal rate of force development (RFD) of the knee extensors, muscle cross-sectional area (CSA) of the quadriceps femoris (QF), muscle fiber proportion, and fiber areas of types I, IIa, IIb, and IIab of the vastus lateralis were evaluated. Maximal and explosive strength values remained unaltered in both groups during a 3-week control period with no training…
Clinical and epidemiological characteristics of pyogenic liver abscess in people 65 years or older versus people under 65: a retrospective study
2017
Abstract Background To analyse the clinical, epidemiological, microbiological and prognostic differences of pyogenic liver abscess (PLA) in older (≥ 65 years of age) versus younger patients (< 65 years). Methods Multicentre, retrospective cohort study in all patients with PLA admitted to two Spanish hospitals from January 2000 to January 2014. Cases were divided into two age groups (< 65 years and ≥65 years) for comparison of clinical, epidemiological and microbiological characteristics as well as treatment. Results Of 98 patients analysed, 40 patients were younger than 65, and 58 were aged 65 or older. Significant associations in the older group were found with female sex (adjusted odds ra…

Assessment of the interest of the geriatric oncology consultation among French general practitioners
2015
International audience; OBJECTIVE: We assessed the interest of the geriatric oncology (GO) consultation (GOC) among general practitioners (GPs). MATERIALS AND METHODS: We conducted a survey among GPs whose patients had had a GOC in 2012. A questionnaire was sent to GPs. The 1st part collected GPs' characteristics including medical education in geriatrics and GO, and knowledge of GOC. The following parts concerned the GOC and included the cancer type, GOC report and care plan. RESULTS: One-hundred twenty-six questionnaires corresponding to 94 GPs were collected. Concerning the GPs' characteristics, age range 50-59 (44.7%), men (62.8%) and urban practice (79.8%) were the most represented, 80.…
Functional correlates of vertical gaze palsy and other ocular motor deficits in PSP: An FDG-PET study
2014
Abstract Objective To determine the functional correlates of vertical gaze palsy and other ocular motor deficits in patients with progressive supranuclear palsy (PSP) using [ 18 F]fluorodeoxyglucose (FDG-)PET. Methods Twenty-six patients with PSP underwent clinical examination of vertical gaze combined with FDG-PET scans to assess regional cerebral glucose metabolism as a marker of neuronal activity. Of these, eighteen PSP patients were also investigated by electrical nystagmography to determine horizontal ocular motor deficits. Statistical parametric mapping analyses were performed to correlate regional neuronal activity with ocular motor functions. Results In categorical comparisons, pati…
Time expenditure in patient-related care provided by specialist palliative care nurses in a community hospice service
2004
Although the importance of specialist palliative care in home care programmes for terminally ill patients is well known, German community hospice services did not begin to employ nurses who had specialized in palliative care until the early 1990s. The general tasks of these nurses are sufficiently well defined, but no comprehensive data of their daily workload are available in Germany to date. The present article examines time expenditure in direct patient-related care at the community-based hospice service in Mainz, Germany, by analysing time registration sheets concerning 351 patients who received care from January 2000 until December 2002. Fifty-five per cent of care time spent on each …
Evaluation of two instruments of perceived symptom intensity in palliative care patients in an outpatient clinic
2015
Aims and objectives To evaluate the test–retest stability in assessments of perceived symptom intensity on the Edmonton Symptom Assessment System-revised and the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire Core 15 Palliative. The possible interchangeability between the instruments and the patients’ experiences of completing the instruments were also studied. Background The two instruments assess the same symptoms, but the symptom intensity is assessed on 11-point numerical scales on the Edmonton Symptom Assessment System-revised and on four-point verbal descriptive scales on the European Organization for Research and Treatment of Cancer, Quality…
How many parkinsonian patients are suitable candidates for deep brain stimulation of subthalamic nucleus? Results of a questionnaire.
2008
We used a CAPSIT-based questionnaire to estimate the percentage of parkinsonian patients suitable for subthalamic nucleus (STN) deep brain stimulation (DBS) in a movement disorders clinic. We found that out of 641 consecutive PD patients only 1.6% fulfilled strict STN-DBS criteria. When we applied more flexible criteria, the percentage of eligibility increased to 4.5%. Most patients (60%) were ineligible because they did not satisfy multiple questionnaire items. Items related to disease severity were responsible for the largest number of exclusions. This knowledge will help make decisions on resource allocation in centres wishing to start DBS surgery.
Quality of life in Parkinson's disease patients with motor fluctuations and dyskinesias in five European countries.
2013
Little is known about the relationship between specific subtypes of treatment-associated motor complications and different domains of health-related Quality of Life (QoL) in patients with Parkinson's disease (PD). Larger studies that investigate these aspects within a cross-cultural setting are scarce.To assess QoL and its association with on-off fluctuations, peak-dose dyskinesias, biphasic dyskinesias, and off-dystonias in PD patients from five European countries.Data from 817 PD patients were collected cross-sectionally in France, Germany, Italy, Spain, and the UK. QoL was measured with the generic EuroQoL 5-Dimension questionnaire (EQ-5D) and the disease-specific Parkinson's Disease Que…
