Normalized mass mapping of Orbitrap data to define complex, polyglycerol-based raw material compositions.

Kendrick Mass Mapping of complex sample compositions, via data derived by Fourier transform ion cyclotron resonance mass spectrometry (FTICRMS) at 1,000,000 resolution, is becoming more common. The Orbitrap mass spectrometer (Fourier Transform Axially Harmonic Orbital Trapping) also uses FT methods and indirect detection, though operating at a maximum resolution of 100,000. We define the more general case of Normalized Mass Mapping to any repeating oligomer unit (e.

Long sick leave after orthopaedic inpatient rehabilitation: treatment failure or relapse?

We investigated whether short-term versus long-term sick leave after orthopaedic inpatient rehabilitation can be predicted by initial assessment information, the clinical status at discharge, or whether the follow-up interval is crucial for later sick leave. We examined 214 patients from an orthopaedic rehabilitation hospital at admission, discharge and 1-year follow-up. Outcome measures included disability, depression, self-efficacy, health status and attitudes towards work.

Separation and analysis of dimethylaniline isomers by supercritical fluid chromatography--electrospray ionization tandem mass spectrometry.

The assessment of human exposure to specific isomers of dimethylanilines (DMA's) is of interest for the evaluation of potential exposure-health outcome relationships. Improved analytical methods will help in identifying the environmental sources of such exposures. The separation of all six DMA isomers by supercritical fluid chromatography (SFC), without derivatization, is reported within.

Evaluation of a behavioral-medical inpatient rehabilitation treatment including booster sessions: a randomized controlled study.

Objectives: The aim of this randomized controlled study was to investigate whether additional psychologic interventions in the context of multidisciplinary inpatient pain treatment increases treatment efficacy compared with normal orthopedic rehabilitation. In addition, we aimed to demonstrate the additional benefit of a subsequent maintenance program in further stabilizing treatment successes.

Methods: We randomly assigned 363 chronic back pain patients to 1 of 3 treatment conditions: traditional orthopedic rehabilitation, multidisciplinary (behavioral-medical) rehabilitation alone, and multidisciplinary rehabilitation with subsequent booster sessions.

[The assignment of orthopaedic rehabilitants to the traditional or the behaviour-medical rehabilitation approach--is it clinically relevant?].

Rehabilitants with chronic orthopaedic diseases are assigned to either the traditional or the behaviour-medical rehabilitation approach by consultant physicians of the rehabilitation department within the Deutsche Rentenversicherung Bund (German pension insurance agency). The clinical relevance of this assignment was evaluated at the Rehazentrum Bad Pyrmont-Klinik Weser within a randomised controlled trial. In a sample of 363 rehabilitants the agreement of consultant physicians with the ratings of physicians and psychologists in the clinic was analyzed.
