RESUMO
BACKGROUND: The Sarcopenia & Quality of Life (SarQoL) questionnaire is a patient-reported outcome measure designed for assessing health-related quality of life in individuals with sarcopenia. Despite its wide acceptance in the scientific literature, its content validity has only been partially demonstrated so far. AIMS: To enhance the evidence supporting the content validity of the SarQoL questionnaire. METHODS: Following COSMIN methodology, semi-structured interviews were conducted with 17 Belgian older adults who met the EWGSOP2 criteria for the diagnosis of sarcopenia and 11 experts in sarcopenia, with clinical or research background. Comprehensiveness, relevance and comprehensibility of SarQoL content were assessed through individual transcripts and were qualitatively analyzed thematically according to the seven dimensions of SarQoL. RESULTS: The majority of the concepts elicited during the semi-structured interviews fitted within existing SarQoL dimensions. Importantly, the different domains of SarQoL were consensually considered as relevant by patients and experts. Some new emergent concepts were identified by the participants. While many of them could be considered as enrichments of existing dimensions or sub-concepts, other new concepts (i.e. self-fulfilment, acceptance of the reduced condition, adaptation/use of strategies, depression) may highlight two potential dimensions not covered by SarQoL, i.e. patient empowerment and depression. Cognitive interviews also highlighted that SarQoL items and instructions were clear and comprehensible. CONCLUSIONS: SarQoL, in its current form, demonstrates good evidence of content validity for assessing health-related quality of life in patients with sarcopenia. We do not recommend adding new items or dimensions to SarQoL. Instead, for researchers or clinicians who aim to specifically address self-empowerment or depression of sarcopenic populations, we suggest completing the assessment of quality of life by concurrently using additional validated scales of patient empowerment or depression.

A large international meta-analysis using primary data from 64 cohorts has quantified the increased risk of fracture associated with a previous history of fracture for future use in FRAX. INTRODUCTION: The aim of this study was to quantify the fracture risk associated with a prior fracture on an international basis and to explore the relationship of this risk with age, sex, time since baseline and bone mineral density (BMD). METHODS: We studied 665,971 men and 1,438,535 women from 64 cohorts in 32 countries followed for a total of 19.5 million person-years. The effect of a prior history of fracture on the risk of any clinical fracture, any osteoporotic fracture, major osteoporotic fracture, and hip fracture alone was examined using an extended Poisson model in each cohort. Covariates examined were age, sex, BMD, and duration of follow-up. The results of the different studies were merged by using the weighted ß-coefficients. RESULTS: A previous fracture history, compared with individuals without a prior fracture, was associated with a significantly increased risk of any clinical fracture (hazard ratio, HR = 1.88; 95% CI = 1.72-2.07). The risk ratio was similar for the outcome of osteoporotic fracture (HR = 1.87; 95% CI = 1.69-2.07), major osteoporotic fracture (HR = 1.83; 95% CI = 1.63-2.06), or for hip fracture (HR = 1.82; 95% CI = 1.62-2.06). There was no significant difference in risk ratio between men and women. Subsequent fracture risk was marginally downward adjusted when account was taken of BMD. Low BMD explained a minority of the risk for any clinical fracture (14%), osteoporotic fracture (17%), and for hip fracture (33%). The risk ratio for all fracture outcomes related to prior fracture decreased significantly with adjustment for age and time since baseline examination. CONCLUSION: A previous history of fracture confers an increased risk of fracture of substantial importance beyond that explained by BMD. The effect is similar in men and women. Its quantitation on an international basis permits the more accurate use of this risk factor in case finding strategies.

Using a discrete choice experiment, we aimed to assess patients' preferences with regard to adopting lifestyle behaviours to prevent osteoporotic fractures. Overall, the 1042 patients recruited from seven European countries were favourable to some lifestyle behaviours (i.e., engaging in moderate physical activity, taking calcium and vitamin D supplements, reducing their alcohol consumption and ensuring a normal body weight). INTRODUCTION: Alongside medical therapy, healthy lifestyle habits are recommended for preventing osteoporotic fractures. In this study, we aimed to assess patients' preferences with regard to adopting lifestyle changes to prevent osteoporotic fractures. METHODS: A discrete choice experiment was conducted in seven European countries. Patients with or at risk of osteoporosis were asked to indicate to what extent they would be motivated to adhere to 16 lifestyle packages that differed in various levels of 6 attributes. The attributes and levels proposed were physical activity (levels: not included, moderate or high), calcium and vitamin D status (levels: not included, taking supplements, improving nutrition and assuring a minimal exposure to sunlight daily), smoking (levels: not included, quit smoking), alcohol (levels: not included, moderate consumption), weight reduction (levels: not included, ensure a healthy body weight) and fall prevention (levels: not included, receiving general advice or following a 1-day fall prevention program). A conditional logit model was used to estimate a patient's relative preferences for the various attributes across all participants and per country. RESULTS: In total, 1042 patients completed the questionnaire. Overall, patients were favourable to lifestyle behaviours for preventing osteoporotic fractures. However, among the lifestyle behaviours proposed, patients were consensually not prone to engage in a high level of physical activity. In addition, in Ireland, Belgium, the Netherlands and Switzerland, patients were also not inclined to participate in a 1-day fall prevention program and Belgian, Swiss and Dutch patients were not prone to adhere to a well-balanced nutritional program. Nevertheless, we observed globally that patients felt positively about reducing their alcohol consumption, engaging in moderate physical activity, taking calcium and vitamin D supplements and ensuring a normal body weight, all measures aimed at preventing fractures. CONCLUSIONS: In a patient-centred approach, fracture prevention should take these considerations and preferences into account.

We describe the collection of cohorts together with the analysis plan for an update of the fracture risk prediction tool FRAX with respect to current and novel risk factors. The resource comprises 2,138,428 participants with a follow-up of approximately 20 million person-years and 116,117 documented incident major osteoporotic fractures. INTRODUCTION: The availability of the fracture risk assessment tool FRAX® has substantially enhanced the targeting of treatment to those at high risk of fracture with FRAX now incorporated into more than 100 clinical osteoporosis guidelines worldwide. The aim of this study is to determine whether the current algorithms can be further optimised with respect to current and novel risk factors. METHODS: A computerised literature search was performed in PubMed from inception until May 17, 2019, to identify eligible cohorts for updating the FRAX coefficients. Additionally, we searched the abstracts of conference proceedings of the American Society for Bone and Mineral Research, European Calcified Tissue Society and World Congress of Osteoporosis. Prospective cohort studies with data on baseline clinical risk factors and incident fractures were eligible. RESULTS: Of the 836 records retrieved, 53 were selected for full-text assessment after screening on title and abstract. Twelve cohorts were deemed eligible and of these, 4 novel cohorts were identified. These cohorts, together with 60 previously identified cohorts, will provide the resource for constructing an updated version of FRAX comprising 2,138,428 participants with a follow-up of approximately 20 million person-years and 116,117 documented incident major osteoporotic fractures. For each known and candidate risk factor, multivariate hazard functions for hip fracture, major osteoporotic fracture and death will be tested using extended Poisson regression. Sex- and/or ethnicity-specific differences in the weights of the risk factors will be investigated. After meta-analyses of the cohort-specific beta coefficients for each risk factor, models comprising 10-year probability of hip and major osteoporotic fracture, with or without femoral neck bone mineral density, will be computed. CONCLUSIONS: These assembled cohorts and described models will provide the framework for an updated FRAX tool enabling enhanced assessment of fracture risk (PROSPERO (CRD42021227266)).

We report the case of a 63-year old patient admitted in the intensive care unit for 25 days because of a severe SARS-CoV-2 pneumonia. With diverse symptoms of critical illness polyneuropathy the patient has been taken care of in a rehabilitation centre. Ankylosis and joint motion limitation led to a more extensive imaging assessment. The later showed advanced periarticular heterotopic calcification in both hips and in right shoulder. Although hypothesis about this complication's physiopathology remains unclear, early identification would allow a better management. It is the first time heterotopic ossification involving three large joints is reported after a SARS-CoV-2 infection.
Nous rapportons le cas d'un patient de 63 ans admis dans une unité de soins intensifs durant 25 jours suite à pneumopathie à SARS-CoV-2 sévère. Le patient a présenté un tableau clinique de polyneuropathie des soins intensifs et a été pris en charge dans un centre de rééducation. L'ankylose et la limitation articulaire des hanches du patient ont conduit à compléter le bilan radiologique montrant d'importantes calcifications hétérotopiques périarticulaires des deux hanches et de l'épaule droite. Bien que les hypothèses physiopathologiques de cette complication restent incertaines, l'identification précoce a permis d'introduire une prise en charge adaptée. C'est la première observation d'ossification hétérotopique associée à une infection à SARS-Cov-2 impliquant trois grandes articulations chez un même patient.

Amyotrophic lateral sclerosis (ALS) is an incurable disease characterized by muscle atrophy leading to complete paralysis. Once diagnosed, the average life expectancy is three to five years. In this context, palliative and end-of-life care are essential, as well as the development of cognitive and/or psychological therapies to improve the quality of life of patients. In this context, we conducted a review of the pertinent literature about psychological and cognitive interventions in end-of-life support for ALS patients. We identified 504 references out of which only four studies met our inclusion criteria. Two studies focused on dignity therapy, one study on the delay between the diagnosis and the start of psychological care in a specialized centre, and one case-report on psychological therapy combined with a computer-assisted communication system. The results of these studies, although very limited, suggest that psychological interventions may improve the management and quality of life of end-of-life ALS patients. Further studies should investigate the impact of psychological support adapted to ALS, using, for example, computer-assisted communication allowing to implement these interventions in a larger number of patients and over the long term.
La sclérose latérale amyotrophique (SLA) est une maladie neurogénérative qui se caractérise notamment par une amyotrophie progressive évoluant jusqu'à la paralysie complète du patient dont l'espérance de vie est, en moyenne, de trois à cinq ans. Les soins palliatifs et le développement de thérapies pour améliorer la qualité de vie des patients sont essentiels. Dans ce cadre, nous avons réalisé une revue de la littérature portant sur les interventions psychologiques et cognitives dans la prise en charge des patients atteins de SLA en fin de vie. Nous avons identifié 504 références dont quatre rapportant des études qui répondaient aux critères d'inclusion. Deux études portaient sur la thérapie de la dignité, une sur la rapidité d'une prise en charge psychologique dans un centre spécialisé et un rapport de cas concernait une prise en charge psychologique combinée à un système de communication assistée par ordinateur. Les résultats de ces quatre études, bien que limités, suggèrent que les interventions psychologiques pourraient améliorer la qualité de vie des patients en fin de vie. De nouvelles recherches devraient être menées pour investiguer l'impact d'une prise en charge psychologique adaptée à la SLA en utilisant, par exemple, une communication assistée afin d'implémenter ces interventions sur un plus grand nombre de patients et sur le long terme.

PURPOSE: To facilitate the measurement of quality of life in sarcopenia, we set out to reduce the number of items in the previously validated Sarcopenia Quality of Life (SarQoL®) questionnaire, and to evaluate the clinimetric properties of this new short form. METHODS: The item reduction process was carried out in two phases. First, information was gathered through item-impact scores from older people (n = 1950), a Delphi method with sarcopenia experts, and previously published clinimetric data. In the second phase, this information was presented to an expert panel that decided which of the items to include in the short form. The newly created SFSarQoL was then administered to older, community-dwelling participants who previously participated in the SarcoPhAge study. We examined discriminative power, internal consistency, construct validity, test-retest reliability, structural validity and examined item parameters with a graded response model (IRT). RESULTS: The questionnaire was reduced from 55 to 14 items, a 75% reduction. A total of 214 older, community-dwelling people were recruited for the validation study. The clinimetric evaluation showed that the SF-SarQoL® can discriminate on sarcopenia status [EWGSOP2 criteria; 34.52 (18.59-43.45) vs. 42.86 (26.56-63.69); p = 0.043], is internally consistent (α = 0.915, ω = 0.917) and reliable [ICC = 0.912 (0.847-0.942)]. A unidimensional model was fitted (CFI = 0.978; TLI = 0.975; RMSEA = 0.108, 90% CI 0.094-0.123; SRMR = 0.055) with no misfitting items and good response category separation. CONCLUSIONS: A new, 14-item, short form version of the Sarcopenia Quality of Life questionnaire has been developed and shows good clinimetric properties.

INTRODUCTION: The association of tobacco use and incidence of muscle impairments has not been extensively explored in research. In this study, the relationship between smoking and the incidence of sarcopenia is investigated. METHODS: The present longitudinal study used data from the Sarcopenia and Physical Impairment with advancing Age (SarcoPhAge) cohort, which includes older adults aged ≥65 years. All individuals with follow-up data on muscle health were included in this post hoc analysis. A diagnosis of sarcopenia was established, at each year of follow-up, according to the European Working Group on Sarcopenia in older People 2 (EWGSOP2) criteria. A sensitivity analysis was performed using other diagnostic criteria for sarcopenia. The smoking status and the number of cigarettes smoked per day were self-reported. The relationship between smoking status or the number of cigarettes smoked per day and the incidence of sarcopenia/severe sarcopenia throughout the 5 years of follow-up was evaluated using the Cox proportional hazards model. RESULTS: In total, the study population included 420 participants, with a median age of 71.7 years (P25-P75 = 67.7-76.9 years) and 59.8% were female. Over the 5 years of follow-up, 78 participants (18.6%) became sarcopenic as per the EWGSOP2 criteria and 41 individuals (9.8%) developed severe sarcopenia. There were significantly more smokers than non-smokers who developed sarcopenia (35.9% vs 16.8%, P-value = 0.003). A fully adjusted Cox model confirmed this observation, yielding a hazard ratio of 2.36 (95% confidence interval [CI]: 1.31-4.26), meaning that smokers have a 2.36-fold higher risk of developing sarcopenia. Furthermore, individuals who smoked had a 2.68 times increased risk of developing severe sarcopenia (95% CI: 1.21-5.93) than those who did not smoke. Sensitivity analyses globally confirmed these findings when applying other diagnostic criteria for sarcopenia. DISCUSSION: Smoking seems to be an important predictor for the onset of sarcopenia, highlighting, once again, that tobacco use is a major public health problem.

BACKGROUND: Ankle sprains are one of the most common musculoskeletal injuries, and can lead to chronic ankle instability (CAI). The Cumberland Ankle Instability Tool (CAIT) measures a subset of CAI, functional ankle instability (FAI). Because no French version existed, we set out to translate and validate the CAIT in French. METHODS: The CAIT was translated using a forward-backward methodology. We examined its psychometric properties and calculated a cut-off score for FAI in a sample of 102 subjects (median age 22 years). RESULTS: The CAIT was translated without significant problems. The CAIT-F can discriminate between those with and without FAI (p < 0.001), with a cut-off score of ≤ 23 points. The test-retest reliability is excellent (ICC = 0.960), as is the internal consistency (α = 0.885). Construct validity was confirmed. No floor or ceiling effects were detected among subjects with FAI. CONCLUSIONS: The CAIT is now available in French, and is a valid and reliable instrument.

The fight against tuberculosis is a public health objective at the world level. The prevention of the hospital-borne tuberculosis by an adequate isolation of the contagious patients is inescapable to eliminate the tuberculosis in Belgium. The Upper Council of the Health set up recommendations relative to the duration and the criteria of the isolation discontinuation. The objective of this study was to estimate the application of these recommendations at Liège University hospital and to determine factors associated to the long stay. The study includes 51 patients affected by pulmonary tuberculosis who were hospitalized in isolation wards within Pneumology department at the Liège University hospital on 1st January 2012 to 31st May 2017. The compliance to the recommendations was observed in 60.8 % and the main reason of the inadequacy of the practices was the isolation discontinuation before 3 negative sputum acid-fast bacilli smears results. The mean duration of isolation was 26.3 ± 19.9 days. Factors associated with the long stay were the high burden of bacilli on initial sputum smear examination (p inferior to 0.001) and the antituberculous treatment delay (p = 0.03).
La lutte contre la tuberculose est un objectif de santé publique à l'échelle mondiale. La prévention de la tuberculose nosocomiale, par un isolement adéquat des malades contagieux, est incontournable. Le Conseil Supérieur de la Santé a mis en place des recommandations, relatives à la durée et aux critères de levée de l'isolement, dans les hôpitaux belges. L'objectif de la présente étude consiste à évaluer la mise en application de ces recommandations au CHU de Liège et de déterminer les facteurs associés au long séjour. Il s'agit d'une étude observationnelle rétrospective incluant 51 patients atteints de tuberculose pulmonaire qui ont été hospitalisés en isolement, au sein du service de Pneumologie du CHU de Liège, durant la période du 01/01/2012 au 31/05/2017. Le respect des recommandations a été observé dans 60,8 % des cas, avec une nette amélioration au cours du temps. La principale cause de non-suivi était la levée d'isolement avant la négativation de trois examens directs. La durée moyenne d'isolement était de 26,3 ± 19,9 jours. Les facteurs associés au long séjour étaient la concentration bacillaire initiale (p inf�rieur a 0,001) et le délai entre l'admission et l'instauration du traitement antituberculeux (p = 0,03).

This study investigated the relationship between muscle and bone status in elderly individuals. Our results suggested links between sarcopenia and osteoporosis; impairment in muscle status (i.e., muscle mass, muscle strength, and physical performance) is associated with deterioration in bone mass and texture subsequently leading to an increased risk of fracture. INTRODUCTION: Accumulating evidence has shown associations between sarcopenia and osteoporosis, but existing studies face inconsistencies in the clinical definition of both conditions. Thus, we sought to investigate bone health among older individuals with or without muscle health impairment. METHODS: We conducted an analysis of cross-sectional data available from the Sarcopenia and Physical Impairment with Advancing Age (SarcoPhAge) study. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People (EWGSOP) (i.e., a low muscle mass plus either low muscle strength or low physical performance). Muscle mass and areal bone mineral density (aBMD) were determined using dual-energy X-ray absorptiometry (DEXA). Muscle strength was assessed using a hand dynamometer, and physical performance was assessed with the Short Physical Performance Battery test. Using the cutoff limits proposed by the EWGSOP, we have classified women in the "low SMI group" when its value was < 5.50 kg/m2, in the "low muscle strength group" when strength was < 20 kg, and in the "low physical performance group" when SPPB < 8 points. The thresholds of < 7.26 kg/m2 (for SMI), < 30 kg (for muscle strength), and SPPB < 8 points were used for men. The 10-year fracture risk was obtained using the FRAX® tool. Moreover, bone texture was determined using the trabecular bone score (TBS) method. RESULTS: The study sample consisted of 288 older subjects aged 74.7 ± 5.7 years, and 59.0% of the subjects were women. Sarcopenia was diagnosed in 43 individuals (14.9%), and osteoporosis was diagnosed in 36 subjects (12.5%). Moreover, aBMD values were, most of the time, lower in older men and women with muscle impairment (i.e., low muscle mass, low muscle strength, and low physical performance). For these subjects, we also noted a higher probability of fracture. When comparing bone quality, there were no significant differences in the TBS values between sarcopenic and non-sarcopenic older men and women or between those with low and high muscle mass. However, when controlling for confounders (i.e., age, BMI, number of co-morbidities, smoking status, and nutritional status), TBS values were lower in older women with low muscle strength (p = 0.04) and in older men with low physical performance (p = 0.01). CONCLUSIONS: Our study showed interrelationships between components of sarcopenia and osteoporosis, with older subjects with muscle impairment having poorer bone health.

This systematic review summarizes the effect of combined exercise and nutrition intervention on muscle mass and muscle function. A total of 37 RCTs were identified. Results indicate that physical exercise has a positive impact on muscle mass and muscle function in subjects aged 65 years and older. However, any interactive effect of dietary supplementation appears to be limited. INTRODUCTION: In 2013, Denison et al. conducted a systematic review including 17 randomized controlled trials (RCTs) to explore the effect of combined exercise and nutrition intervention to improve muscle mass, muscle strength, or physical performance in older people. They concluded that further studies were needed to provide evidence upon which public health and clinical recommendations could be based. The purpose of the present work was to update the prior systematic review and include studies published up to October 2015. METHODS: Using the electronic databases MEDLINE and EMBASE, we identified RCTs which assessed the combined effect of exercise training and nutritional supplementation on muscle strength, muscle mass, or physical performance in subjects aged 60 years and over. Study selection and data extraction were performed by two independent reviewers. RESULTS: The search strategy identified 21 additional RCTs giving a total of 37 RCTs. Studies were heterogeneous in terms of protocols for physical exercise and dietary supplementation (proteins, essential amino acids, creatine, ß-hydroxy-ß-methylbuthyrate, vitamin D, multi-nutrients, or other). In 79% of the studies (27/34 RCTs), muscle mass increased with exercise but an additional effect of nutrition was only found in 8 RCTs (23.5%). Muscle strength increased in 82.8% of the studies (29/35 RCTs) following exercise intervention, and dietary supplementation showed additional benefits in only a small number of studies (8/35 RCTS, 22.8%). Finally, the majority of studies showed an increase of physical performance following exercise intervention (26/28 RCTs, 92.8%) but interaction with nutrition supplementation was only found in 14.3% of these studies (4/28 RCTs). CONCLUSION: Physical exercise has a positive impact on muscle mass and muscle function in healthy subjects aged 60 years and older. The biggest effect of exercise intervention, of any type, has been seen on physical performance (gait speed, chair rising test, balance, SPPB test, etc.). We observed huge variations in regard to the dietary supplementation protocols. Based on the included studies, mainly performed on well-nourished subjects, the interactive effect of dietary supplementation on muscle function appears limited.

Sarcopenia is a major public health issue. To convince health policy makers of the emergency to invest in the sarcopenia field, it is of critical importance to produce reliable figures of the expected burden of sarcopenia in the coming years. Age- and gender-specific population projections were retrieved until 2045 from the Eurostat online database (28 European countries). Age- and gender-specific prevalences of sarcopenia were interpolated from a study that compared prevalence estimates according to the different diagnostic cutoffs of the EWGSOP proposed definition. The reported prevalence estimates were interpolated between 65 and 100 years. Interpolated age- and gender-specific estimates of sarcopenia prevalence were then applied to population projections until 2045. Using the definition providing the lowest prevalence estimates, the number of individuals with sarcopenia would rise in Europe from 10,869,527 in 2016 to 18,735,173 in 2045 (a 72.4% increase). This corresponds to an overall prevalence of sarcopenia in the elderly rising from 11.1% in 2016 to 12.9% in 2045. With the definition providing the highest prevalence estimates, the number of individuals with sarcopenia would rise from 19,740,527 in 2016 to 32,338,990 in 2045 (a 63.8% increase), corresponding to overall prevalence rates in the elderly of 20.2% and 22.3% for 2016 and 2045, respectively. We showed that the number of sarcopenic patients will dramatically increase in the next 30 years, making consequences of muscle wasting a major public health issue.

OBJECTIVE: To investigate the relationship between frailty and sarcopenia, by evaluating the prevalence of sarcopenia among frail, pre-frail and robust elderly nursing home residents in Belgium. METHODS: This is an analysis of baseline data collected from the SENIOR (Sample of Elderly Nursing home Individuals: an Observational Research) cohort. All subjects received a sarcopenia evaluation, based on the definition proposed by the European Working Group on Sarcopenia in Older People (EWGSOP). The frailty evaluation was primarily based on FRIED's definition but also on 9 other operational definitions. RESULTS: A total of 662 subjects (73.1% of women) were included in this analysis (mean age: 83.2±8.99 years). The prevalence of sarcopenia was 38.1% whereas the prevalence of frail and pre-frail persons was respectively 24.7% and 61.4%. Among frail, pre-frail and robust subjects, respectively 47%, 38.9% and 16.3% were diagnosed sarcopenic. The prevalence of sarcopenia according to ten different operational definitions of frailty ranged between 32.8 % (i.e. Frail scale Status and Frailty Index) and 47% (i.e. Fried definition). CONCLUSION: This research highlights that over a third of nursing home residents are sarcopenic and the percentage is almost 50% among frail subjects; those latter constitute about 1 in 4 of the population of nursing home residents studied here.

BACKGROUND: The aim of this study was to assess the relationship between frailty and a large number of indicators related to physical and muscular performance as well as quality of life. METHODS: This is an analysis of data collected at baseline in the Sample of Elderly Nursing home Individuals: an Observational Research (SENIOR) cohort including nursing home residents. Subjects are volunteer, oriented and able to walk (walking assistance allowed) nursing home residents in Belgium. A large number of demographic and clinical characteristics, including physical and muscular performance, were collected from each patient. The prevalence of frailty in this population was assessed using Fried's definition. RESULTS: In total, 662 subjects are included in this analysis. The mean age of the sample is 83.2 ± 8.99 years, and 484 (73.1 %) are women. In this population of nursing home residents, the prevalence of frailty is 25.1 %, pre-frailty, 59.8 % and robustness, 15.1 %. Compared to non-frail subjects, frail subjects have lower physical and muscular performances and a lower quality of life. CONCLUSION: Frailty, according to Fried's definition, seems to be associated with several clinical indicators suggesting a higher level of disability and an increased propensity to develop major clinical consequences. Follow-up data of the SENIOR cohort will be helpful in confirming these findings, establishing cause-effect relationships and identifying the most predictive components of physical frailty for adverse outcomes in nursing homes.

The aim of this study was to evaluate the interest in the Internet and its usage for health-related issues among people eligible for osteoporosis screening. Self-administered questionnaires have been distributed to subjects who were screened for osteoporosis and to menopausal women. 177 patients have responded to the survey (64.5 ± 10.1 years, 88.1% of women). There are 78.5% of Internet users. Among them, 67.2% said searching information about their health and 74.5% said using the Internet for this purpose. All respondents attributed an average score, out of 10, of 5.7 ± 2.3 regarding the reliability of information that they could find on the Internet. The use of the Internet differs significantly depending on age: those who use the Internet are younger (62.1 ± 8.91 years) than those who do not use it (73.3 ± 9.42 years). The socioeconomic status also has an impact on the Internet use: Internet users have a higher education, are more professionally active and have a higher net monthly household income compared to the group of non-users. Even if age and socioeconomic status appear to be determining factors in the use of the Internet for the search of health information in patients eligible for osteoporosis screening, almost 75% of the study population use the Internet for this purpose. Action to promote health through an Internet platform must therefore take these parameters into account.

Osteoporosis is at the very early stages of the implementation of personalized medicine. However, the development of FRAX®, an algorithm offering the opportunity to calculate, in an individual patient, his/her 10-year fracture risk improves the decision process on the appropriateness to initiate a pharmacological treatment. This algorithm helps the physician to select drugs which are active on non-vertebral fractures only in high risk patients. Taking into consideration patients' preferences, when selecting a therapeutic option, will improve long term adherence and subsequently efficacy and efficiency of the treatments. Attempts to define the natural course of osteoporosis or the response to therapy in individual patients by assessing their genetic profile remains, so far, inconclusive.

INTRODUCTION: In the definition of the European Working Group on Sarcopenia in Older People (EWGSOP), different cut-off limits are proposed for appendicular lean mass, muscle strength and gait speed. Therefore we aimed to examine the variation in prevalence of sarcopenia obtained with these cut-off limits. MATERIALS AND METHODS: Subjects aged 65 years and older were recruited in an outpatient clinic in Belgium and screened for sarcopenia using the EWGSOP definition. Appendicular lean mass was measured by Dual Energy X-Ray Absorptiometry, muscle strength by a hydraulic handgrip dynamometer and gait speed was measured on a 4-meter distance. Two different cut-off points proposed by the EWGSOP were examined for each variable and 8 diagnostic methods were thereby established. RESULTS: 400 subjects were recruited for this study. Prevalence of sarcopenia varied from 9.25% to 18% depending on the cut-offs applied. When stratified by sex, it seems that the variation in prevalence of sarcopenia was mainly attributable to women. This prevalence ranged from 6.58% to 20.2% for women and only from 13.4% to 14.7% for men. CONCLUSION: Prevalence of sarcopenia varies widely depending on the EWGSOP cut-off points applied for women. This may limit clinical researches and development of therapeutic strategies in the field of sarcopenia.

BACKGROUND: We have previously shown that short sessions of whole body vibration (WBV) were not able to significantly improve fall risk among nursing home residents but some trends towards an improvement of motor capacity were observed. OBJECTIVE: The objective of the present study was to evaluate the impact of 6-month training by WBV on functional and motor abilities among nursing home residents observed over a 12-month period. METHODS: Patients were randomized into two groups: the WBV group which received three training sessions every week composed of five series of 15 s of vibration at 30 Hz intensity for a period of 6 months and a control group with normal daily life. The impact of this training on the risk of falls was assessed blindly after 6 and 12 months by the Tinetti Test, the "Timed Up and Go" test and a quantitative evaluation of a 10-s walk performed with a tri-axial accelerometer. The occurrence of falls was also observed. RESULTS: 62 elderly healthy volunteers, (47 women and 15 men, mean age 83.2 ± 7.9 years) were included in this study. There was no significant difference between the two groups regarding the Tinetti test (p = 0.75), the "Timed Up and Go" test (p = 0.19) and the Locométrix(®) test, except for the step length, measured by dual task (p < 0.01). No significant inter-group difference in the frequency of falls was observed during the 12 months of research. A total of 42 falls were recorded during the first 6 months of experimentation: 24 falls in the treated group and 18 in the control group (p = 0.60). During the next 6 months, 19 falls occurred: 8 falls in the treated group and 11 in the control group (p = 0.52). CONCLUSION: This study failed to establish the effectiveness of low doses of WBV, under the conditions used in our study, on functional and motor abilities of institutionalized elderly patients. However, given the positive results of other studies, further investigations, with modified therapeutic protocols, seem necessary to clarify the effects of WBV in the elderly.

The term "sarcopenia" was first introduced in 1989 by Irwin Rosenberg to define a progressive and generalized loss of muscle mass and muscle strength with advancing age. Above certain thresholds, that loss of muscle mass and muscle strength is considered abnormal. Despite the progress of scientific knowledge, a universally accepted definition of sarcopenia is still lacking to date. Therefore, it is a real challenge to establish the prevalence of sarcopenia because the results highly depend on the definition used for its diagnosis. This geriatric syndrome represents a public health issue with multiple clinical consequences. Loss of autonomy and quality of life, altered functional status, increase of fatigue, falls and a higher mortality rate are well-known consequences of sarcopenia. Although many pharmacological and non-pharmacological therapeutical strategies seem to have a positive impact on muscle strength and muscle mass, very few studies have yet assessed the effects of those treatments on sarcopenia itself. Therefore, developing high-quality interventional studies, in this field, seem necessary.
