Variability in echolocation call design of 26 Swiss bat species: consequences, limits and options for automated field identification with a synergetic pattern recognition approach

Pattern recognition algorithms offer a promising approach to recognizing bat species by their echolocation calls. Automated systems like synergetic classifiers may contribute significantly to operator-independent species identification in the field. However, it necessitates the assembling of an appropriate database of reference calls, a task far from trivial. We present data on species specific flexibility in call parameters of all Swiss bat species (except Nyctalus lasiopterus and Plecotus alpinus). The selection of "training-calls" for the classifier is crucial for species identification success. We discuss this in the context of echolocation call variability differing between species and its consequences for the implementation of an automated, species specific bat activity monitoring syste

Mycobacterium-avium -Pneumonie bei HIV-negativem Patienten

Zusammenfassung: Ein 79-jähriger Patient mit kurativ behandeltem Lungenkarzinom wurde wegen Fieber, Atemnot und Husten zugewiesen. Eine Antibiotikatherapie zur Pneumoniebehandlung brachte keine Besserung, und radiologisch war die Pneumonie progredient. Ein Erreger konnte nicht gefunden werden. Erst unter einer Steroidtherapie bei vermuteter kryptogener Pneumonitis normalisierten sich die Entzündungszeichen und die Symptomatik war rückläufig. Nach 3-wöchiger Kultivierung konnten im Eintrittssputum Mycobacterium avium Complex (MAC) gefunden und eine MAC-Pneumonie diagnostiziert werde

Throat Swabs Are Necessary to Reliably Detect Carriers of Staphylococcus aureus

The anterior nares are the most important screening site of colonization with Staphylococcus aureus. We screened 2966 individuals for S. aureus carriage with swabs of both nares and throat. A total of 37.1% of persons were nasal carriers, and 12.8% were solely throat carriers. Screening of throat swabs significantly increases the sensitivity of detection among carriers by 25.7

Serial monitoring of pancreatic stone protein for the detection of sepsis in intensive care unit patients with complicated abdominal surgery: A prospective, longitudinal cohort study.

The objective of this study was to assess the performance of pancreatic stone protein (PSP) monitoring for the detection of sepsis, prediction of outcome and distinction between bacterial and fungal infections in intensive care unit (ICU) patients with complicated abdominal surgery. In this prospective multicenter cohort study, patients with complicated abdominal surgery had serial PSP measurements during their ICU stay. Infectious episodes were classified as bacterial, fungal or mixed. PSPmax (maximal PSP value within 48 h of the diagnosis of infection) and ΔPSP (difference between PSPmax and the preceding PSP value) were used for analyses. PSPmax was obtained for 118 infectious episodes (68 patients). ΔPSP was available for 73 episodes (48 patients). Both PSPmax and ΔPSP were significantly higher in patients with sepsis and in patients with a fatal outcome. A PSPmax ≥124 ng/ml and a ΔPSP ≥34 ng/ml could detect sepsis with a sensitivity/specificity of 84%/54% and 69%/76%, respectively. There was no significant difference of PSPmax or ΔPSP between patients with bacterial/mixed versus fungal infections. Serial PSP monitoring may be an additional tool for the early detection of sepsis in patients with complicated abdominal surgery who are at high risk of severe infections

Galactic Abundances: Report of Working Group 3

We summarize the various methods and their limitations and strengths to derive galactic abundances from in-situ and remote-sensing measurements, both from ground-based observations and from instruments in space. Because galactic abundances evolve in time and space it is important to obtain information with a variety of different methods covering different regions from the Very Local Insterstellar Medium (VLISM) to the distant galaxy, and different times throughout the evolution of the galaxy. We discuss the study of the present-day VLISM with neutral gas, pickup ions, and Anomalous Cosmic Rays, the study of the local interstellar medium (ISM) at distances <1.5 kpc utilizing absorption line measurements in H I clouds, and the study of galactic cosmic rays, sampling contemporary (~15 Myr) sources in the local ISM within a few kiloparsec of the solar system. Solar system abundances, derived from solar abundances and meteorite studies are discussed in several other chapters of this volume. They provide samples of matter from the ISM from the time of solar system format ion, about 4.5 Gyr ago. The evolution of galactic abundances on longer time scales is discussed in the context of nuclear synthesis in the various contributing stellar objects

Validation of modelling the radiation exposure due to solar particle events at aircraft altitudes

Dose assessment procedures for cosmic radiation exposure of aircraft crew have been introduced in most European countries in accordance with the corresponding European directive and national regulations. However, the radiation exposure due to solar particle events is still a matter of scientific research. Here we describe the European research project CONRAD, WP6, Subgroup-B, about the current status of available solar storm measurements and existing models for dose estimation at flight altitudes during solar particle events leading to ground level enhancement (GLE). Three models for the numerical dose estimation during GLEs are discussed. Some of the models agree with limited experimental data reasonably well. Analysis of GLEs during geomagnetically disturbed conditions is still complex and time consuming. Currently available solar particle event models can disagree with each other by an order of magnitude. Further research and verification by on-board measurements is still neede

A rifampicin-containing antibiotic treatment improves outcome of staphylococcal deep sternal wound infections

Background Deep sternal wound infection (DSWI) is a severe complication after cardiac surgery, mostly caused by staphylococci. Little is known about the optimal antibiotic management. Methods A 10 year retrospective analysis of 100 patients with staphylococcal DSWI after cardiac surgery in a tertiary hospital. Treatment failure was defined as sternal wound dehiscence or fistula at the end of the prescribed antibiotic therapy, 12 months later, or DSWI-related death. Results Most patients were male (83%) and the median age was 72 years [interquartile range (IQR) 63-76]. Coronary artery bypass was the most frequent preceding procedure (93%). The median time to diagnosis of DSWI was 13 days (IQR 10-18) after surgery. Clinical presentation consisted of wound discharge in 77% of patients. Coagulase-negative staphylococci were isolated in 54 and Staphylococcus aureus in 46 patients. All patients received antibiotics and 95% underwent surgical debridement. The median duration of antibiotic treatment was 47 days (IQR 41-78). During follow-up, 21 out of 100 patients experienced treatment failure. Of these, 8/21 patients (38%) died from DSWI after a median of 12 days (IQR 8-30). In the multivariate analysis, a rifampicin-containing antibiotic regimen was the only factor associated with lower risk of treatment failure (hazard ratio 0.26, 95% confidence interval 0.10-0.64, P = 0.004). Prolonged treatment (12 weeks instead of 6 weeks) did not alter outcome (P = 0.716) in patients without prosthetic valve endocarditis. Conclusions Treatment of rifampicin-susceptible staphylococcal DSWI with a rifampicin-containing antibiotic regimen may improve the outcome. After surgical debridement an antibiotic treatment of 6 weeks may be adequate for staphylococcal DSW
