No full textImplications of ICD-10 for Sarcopenia Clinical Practice and Clinical Trials: Report by the International Conference on Frailty and Sarcopenia Research Task Force.
No full textpeer reviewedEstablishment of an ICD-10-CM code for sarcopenia in 2016 was an important step towards reaching international consensus on the need for a nosological framework of age-related skeletal muscle decline. The International Conference on Frailty and Sarcopenia Research Task Force met in April 2017 to discuss the meaning, significance, and barriers to the implementation of the new code as well as strategies to accelerate development of new therapies. Analyses by the Sarcopenia Definitions and Outcomes Consortium are underway to develop quantitative definitions of sarcopenia. A consensus conference is planned to evaluate this analysis. The Task Force also discussed lessons learned from sarcopenia trials that could be applied to future trials, as well as lessons from the osteoporosis field, a clinical condition with many constructs similar to sarcopenia and for which ad hoc treatments have been developed and approved by regulatory agencies
A search for flaring very-high-energy cosmic gamma-ray sources with the L3+C muon spectrometer
No full textThe L3+C muon detector at the CERN electron-positron collider, LEP, is used for the detection of very-high-energy cosmic gamma-ray sources through the observation of muons of energies above 20, 30, 50 and 100 GeV. Daily or monthly excesses in the rate of single-muon events pointing to some particular direction in the sky are searched for. The periods from mid July to November 1999, and April to November 2000 are considered. Special attention is also given to a selection of known gamma-ray sources. No statistically significant excess is observed for any direction or any particular source. (c) 2006 Elsevier B.V. All rights reserved
The “Sarcopenia and Physical fRailty IN older people: multi-componenT Treatment strategies” (SPRINTT) randomized controlled trial: Case finding, screening and characteristics of eligible participants
No full textBackground: The ongoing “Sarcopenia and Physical fRailty IN older people: multi-componenT Treatment strategies (SPRINTT)” randomized controlled trial (RCT) is testing the efficacy of a multicomponent intervention in the prevention of mobility disability in older adults with physical frailty & sarcopenia (PF&S). Here, we describe the procedures followed for PF&S case finding and screening of candidate participants for the SPRINTT RCT. We also illustrate the main demographic and clinical characteristics of eligible screenees. Methods: The identification of PF&S was based on the co-occurrence of three defining elements: (1) reduced physical performance (defined as a score on the Short Physical Performance Battery between 3 and 9); (2) low muscle mass according to the criteria released by the Foundation for the National Institutes of Health; and (3) absence of mobility disability (defined as ability to complete the 400-m walk test in 15 min). SPRINTT was advertised through a variety of means. Site-specific case finding strategies were developed to accommodate the variability across centers in catchment area characteristics and access to the target population. A quick “participant profiling” questionnaire was devised to facilitate PF&S case finding. Results: During approximately 22 months, 12,358 prescreening interviews were completed in 17 SPRINTT sites resulting in 6710 clinic screening visits. Eventually, 1566 candidates were found to be eligible for participating in the SPRINTT RCT. Eligible screenees showed substantial physical function impairment and comorbidity burden. In most centers, project advertisement through mass media was the most rewarding case finding strategy. Conclusion: PF&S case finding in the community is a challenging, but feasible task. Although largely autonomous in daily life activities, older adults with PF&S suffer from significant functional impairment and comorbidity. This subset of the older population is therefore at high risk for disability and other negative health-related events. Key strategies to consider for successfully intercepting at-risk older adults should focus on mass communication methods

No full textGeneralized event shape and energy flow studies in e+e− annihilation at √s=912−2080 GeV
No full textWe present results from a study of hadronic event structure in high energy e(+)e(-') interactions using the L3 detector at LEP. A new class of event shape distributions are measured at and above the Z boson pole for light quark (u, d, s, c) flavours. Energy flow correlations are studied for all hadronic events. Next-to-leading-log QCD calculations and QCD models with improved leading-log approximations are compared to data and good agreement is found at the Z-pole whereas some discrepancies are observed at higher centre-of-mass energies
Study of hadronic event shape in flavour tagged events in e+e- annihilation at = 197 GeV
No full textResults are presented from a study of the structure of hadronic events in highenergy (e^+)(e^-) interactions detected by the L3 detector at LEP. Various event shape distributions and their moments are measured at several energy points at and above the Z-boson mass. The event avour is tagged by using the decay characteristics of b-hadrons. Measurements of distributions of event shape variables for all hadronic events, for light (u, d, s, c) and heavy (b) quark avours are compared to several QCD models with improved leading log approximation: Jetset, Herwig and Ariadne. A good description of the data is provided by the models.Results are presented from a study of the structure of hadronic events in high-energy e+e- interactions detected by the L3 detector at LEP.

Studies of hadronic event structure in e(+)e(-) annihilation from 30 to 209 GeV with the L3 detector
No full textIn this Report, QCD results obtained from a study of hadronic event structure in high energy e(+)e(-) interactions with the L3 detector are presented. The operation of the LEP collider at many different collision energies from 91 to 209 GeV offers a unique opportunity to test QCD by measuring the energy dependence of different observables. The main results concern the measurement of the strong coupling constant, as, from hadronic event shapes and the study of effects of soft gluon coherence in charged particle multiplicity and momentum distributions.

Analysis of the pi(+) pi(-) pi(+)pi(-) and pi(+)pi(0) pi(-) pi(0) final states in quasi-real two-photon collisions at LEP
No full textThe reactions gamma gamma -\u3e pi(+)pi(-)pi(+)pi(-) and gamma gamma -\u3e pi(+)pi(0)pi(-)pi(0) are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161 GeV to 209 GeV with a total integrated luminosity of 698 pb(-1). A spin-parity-helicity analysis of the rho(0)rho(0) and p(+)p(-) systems for two-photon centre-of-mass energies between 1 and 3 GeV shows the dominance of the spin-parity state 2(+) with helicity 2. The contribution of 0(+) and 0(-) spin-parity states is also observed, whereas contributions of 2(-) states and of a state with spin-parity 2(+) and zero helicity are found to be negligible.
