Sarcopenia is defined by loss of muscular mass, strength and quality that occur in elderly. Multiple factors underlie this process: low physical activity, low steroids hormones, increase of cytokines, loss of motoneurons, decrease of protein synthesis...However, the role of these factors is not yet well understood and consensual clinical definition and assessment are still needed. It has become an important area of research because of its frequency and the influence in the disability of old people. It is a major component of frailty. So far, no pharmacological treatment has proven definitive evidence to treat or prevent sarcopenia. Nevertheless, it needs a multidimensional approach based on physical activity and prevention of malnutrition. [less ▲]

BACKGROUND: In order to address the challenges of an ageing population the Belgian government decided to allocate resources to the creation of geriatric day hospitals (GDHs). Although GDHs are meant to be a strategy to support general practitioners (GPs) caring for the frail elderly, few Belgian GPs seem to refer to a GDH. This study aims to explore the barriers and facilitating factors of GPs' referral to GDHs. METHODS: A qualitative study using focus group discussions (FGDs) was conducted. Fifteen FGDs were organized in the different Belgian regions (Flanders, Wallonia, Brussels). RESULTS: Contextual factors such as the unsatisfactory cooperation between hospital and GPs and organizational barriers such as the lack of communication on referral procedures between hospital and primary health care (PHC) were identified. Lack of basic knowledge about the concept or the local organization of GDH seemed to be a problem. Unclear task descriptions, responsibilities and activities of a GDH formed prominent points of discussion in all FGDs. Nevertheless a lot of possible advantages and disadvantages of GDHs for the patient and for the GP were mentioned. CONCLUSIONS: In the case of poor referral to GDHs, focusing on improving overall collaboration between primary and secondary health care is essential. This can be achieved by actively delivering adequate information, permanent communication and more involvement of PHC in the organization and functioning of GDHs. The absence of a transparent health care system with delineated role definitions, seems to hinder the integration of new initiatives like GDHs in the care process. Strategies to enhance referral to GDHs should use a comprehensive approach. [less ▲]

To support policy makers combating travel-related externalities, quality data are required for the design and management of transportation systems and policies. To this end, much money has been spent on collecting household- and person-based data. The main objective of this paper is to assess the quality of origin-destination (O-D) matrices derived from household activity travel surveys. To this purpose, a Monte Carlo experiment is set up to estimate the precision of O-D matrices given different sampling rates. The Belgian 2001 census data, containing work- and school-related travel information for all 10,296,350 residents, are used for the experiment. For different sampling rates, 2,000 random stratified samples are drawn. For each sample, three O-D matrices are composed: one at the municipality level, one at the district level, and one at the provincial level. The correspondence between the samples and the population is assessed by using the mean absolute percentage error (MAPE) and a censored version of the MAPE (MCAPE). The results show that no accurate O-D matrices can be derived directly from these surveys. Only when half of the population is queried is an acceptable O-D matrix obtained at the provincial level. Therefore, use of additional information to grasp better the behavioral realism underlying destination choices and collection of information about particular O-D pairs by means of vehicle intercept surveys are recommended. In addition, results suggest using the MCAPE next to traditional criteria to examine dissimilarities between different O-D matrices. An important avenue for further research is the investigation of the effect of sampling proportions on travel demand model outcomes. [less ▲]

Mediastin pathology includes primary lesion and lymph node invasion. The exploration of this anatomical region remains difficult and even hazardous, particularly to obtain histological biopsies. No invasive diagnostic exploration (thorax tomodensitometry and positron emission tomography) allows a histological precision, so mediastinoscopy remains the gold standard in the mediastinum investigation. However, it is not deprived of risk. Recently, guided biopsies and real-time transbronchial needle aspiration by endobronchial ultrasonography (EBUS) have been shown to increase the diagnostic yield over conventional bronchoscopic techniques. Therefore, EBUS is a suitable alternative to mediastinoscopy in the diagnosis of pulmonary or extra-thoracic malignancy, in the staging of mediastinal lymphadenopathy, and in the evaluation of mediastinal response after induction therapy. In the present paper, we present this new diagnostic approach and clarify the current indications of EBUS. [less ▲]
