    Description / Table of Contents: Summary Surgical interventions in the petrous bone have to be performed in close relationship to vital and delicate anatomical structures. In cases of revision surgery or with massive pathological changes 3D computer-assisted navigation provides an essential tool for preoperative planning, definition of target structures and intraoperative orientation. This technology can help to diminish intraoperative risks for the patient and may help to optimize any microsurgery. In this report we present our first experiences in using the ISG Viewing Wand in the petrous bone through a specially designed model. By recording more than 4000 single measurements we found that the ISG Viewing Wand can be used with sufficient precision. We have now outlined the most important conditions necessary for possible application to a patient.
    Notes: Zusammenfassung Chirurgische Eingriffe am Felsenbeim werden in engster Nachbarschaft von vitalen Strukturen durchgeführt. Bei Revisionsoperationen oder bei ausgedehnten pathologischen Veränderungen kann der Chirurg durch den Einsatz computerunterstützter intraoperativer 3D-Navigation zur Orientierung und Definition von Zugangswegen sowie Zielstrukturen, Operationsrisiken entscheidend verringern. Wir zeigen die Möglichkeiten und Grenzen eines Einsatzes der ISG Viewing Wand (ISG Technologies, Mississauga, Ontario, Kanada) für dieses neue Einsatzgebiet anhand von Genauigkeitsmessungen an einem Felsenbeinmodell auf. Die unter möglichst realistischen Bedingungen durchgeführten Messungen am Modell zeigen, daß die ISG Viewing Wand unter bestimmten Voraussetzungen bei Eingriffen am Felsenbein verwendet werden kann, so daß der Operateur eine zuverlässige intraoperative Navigation zur Verfügung hat. Wir präsentieren die Ergebnisse aus über 4000 Einzelmessungen und skizzieren einen möglichen Einsatz am Patienten.

    Diagnostic value of the DSM and ICD categories of psychosis: an evidence-based approach (2000)
    Springer

    Notes: Abstract Background: It is generally assumed that the distinction between affective and non-affective psychosis occasioned by modern diagnostic criteria provides a useful symptomatic contrast. Method: In a sample of 708 patients with chronic psychosis, the distinction of lifetime DSM-III-R and ICD-10 diagnoses of affective versus non-affective psychosis was used as a diagnostic test to detect lifetime presence of depressive, manic, positive, negative and disorganisation symptoms. Results: A manic or depressive affective diagnosis was a perfect test to diagnose the presence of manic and depressive symptoms, as evidenced by very high diagnostic likelihood ratios. However, this test result was based solely on the inclusion criterion that patients with affective psychosis must have affective symptoms (guaranteeing high specificity and high likelihood ratios), and ignored the fact that patients with non-affective psychosis also had high affective symptom scores (low sensitivity). Furthermore, a non-affective psychotic diagnosis was a very poor test to diagnose correctly the presence of positive, negative and disorganisation symptoms in comparison with an affective psychotic diagnosis. In general, the DSM-III-R categories performed somewhat better as a diagnostic test than those of ICD-10. Conclusion: The evidence for true diagnostic value of the distinction between affective and non-affective psychotic diagnoses is weak. Rather, the distinction appears to obscure natural overlap between the symptom dimensions of the different diagnostic categories.

    Description: Which animals use their energy better during movement? One metric to answer this question is the energy cost per unit distance per unit weight. Prior data show that this metric decreases with mass, which is considered to imply that massive animals are more efficient. Although useful, this metric also implies...

    Recent human-induced atmospheric drying across Europe unprecedented in the last 400 years (2024)
    In:  Nature Geoscience
    Details
    Publication Date: 2024-01-19
    Description: The vapor pressure deficit reflects the difference between how much moisture the atmosphere could and actually does hold, a factor that fundamentally affects evapotranspiration, ecosystem functioning, and vegetation carbon uptake. Its spatial variability and long-term trends under natural versus human-influenced climate are poorly known despite being essential for predicting future effects on natural ecosystems and human societies such as crop yield, wildfires, and health. Here we combine regionally distinct reconstructions of pre-industrial summer vapor pressure deficit variability from Europe’s largest oxygen-isotope network of tree-ring cellulose with observational records and Earth system model simulations with and without human forcing included. We demonstrate that an intensification of atmospheric drying during the recent decades across different European target regions is unprecedented in a pre-industrial context and that it is attributed to human influence with more than 98% probability. The magnitude of this trend is largest in Western and Central Europe, the Alps and Pyrenees region, and the smallest in southern Fennoscandia. In view of the extreme drought and compound events of the recent years, further atmospheric drying poses an enhanced risk to vegetation, specifically in the densely populated areas of the European temperate lowlands.
