Impact of vegetation composition and seasonality on sensitivity of modelled CO exchange in temperate raised bogs.

Encroachment of vascular plants (VP) in temperate raised bogs, as a consequence of altered hydrological conditions and nutrient input, is widely observed. Effects of such vegetation shift on water and carbon cycles are, however, largely unknown and identification of responsible plant physiological traits is challenging. Process-based modelling offers the opportunity of gaining insights into ecosystem functioning beyond observations, and to infer decisive trait shifts of plant functional groups.

[Resilience of German clinics in amok and terrorist situations : Results of an online-based survey in German emergency departments].

Background: As a critical infrastructure (CRITIS) and soft target with high symbolic power, hospitals have to prepare for terrorist attacks, rampages, and establish damage-prevention measures.

Method: The terrorist threat situation was quantified using an evaluation of the terrorist event database (TED) from 1970 to 2017. Additionally, the threat perception and precautionary measures were recorded by an online survey among the leaders of German emergency departments.

[Resilience of the critical infrastructure in hospitals : Categorization and quantification as a basis for optimization].

Background: Critical infrastructure (CRITIS) in hospitals has become the focus of resilience research due to the impact of the COVID-19 pandemic and also the events in Ukraine. This foundational research examines overall contexts, categorizing and quantifying them. Previous research examined limited scale damage situations with little CRITIS involvement: Worst case studies are missing.

Successful simultaneous targeting of IgE and IL-5 in a severe asthmatic patient selected for lung transplantation.

We report a case of severe uncontrolled allergic and eosinophilic asthma in which omalizumab had led to a fast remission. After 18 months, mepolizumab was added to omalizumab because of increased blood eosinophils and a deterioration of asthma control. Asthma was then under control for the next 18 months.

[Relevance of disaster and deployment medicine for medical students : A pilot study based on an interdisciplinary lecture series].

Background: The global rise of conflicts and catastrophes causes new challenges for western healthcare systems. There are obvious parallels between civilian disaster medicine and military combat care. The integration of disaster and deployment medicine into the medical curriculum thus seems necessary.

Over the course of the past decade the Charité-Universitätsmedizin Berlin has taken steps to improve the quality of the theses completed by its doctoral students in medicine and increase their publication activity. This study was designed to verify the efficacy of these measures and to detect general trends.

[Long-term liver damage due to trauma].

Severe trauma has a major influence on the visceral organs, especially on the liver. Splanchnic hypotension leads to necrosis of the bile duct cells as well as to damage to hepatocytes. Furthermore, the liver is a very immunologically active organ so that damage to the liver can increase the amount of proinflammatory cytokines.

Imaging findings in acute invasive pulmonary aspergillosis: clinical significance of the halo sign.

Background: Computed tomography (CT) of the chest may be used to identify the halo sign, a macronodule surrounded by a perimeter of ground-glass opacity, which is an early sign of invasive pulmonary aspergillosis (IPA). This study analyzed chest CT findings at presentation from a large series of patients with IPA, to assess the prevalence of these imaging findings and to evaluate the clinical utility of the halo sign for early identification of this potentially life-threatening infection.

Methods: Baseline chest CT imaging findings from 235 patients with IPA who participated in a previously published study were systematically analyzed.

Abdominal and iliac arterial stenoses: comparative double-blinded randomized study of diagnostic accuracy of 3D MR angiography with gadodiamide or gadopentetate dimeglumine.

Purpose: To prospectively evaluate accuracy of gadolinium-enhanced three-dimensional (3D) magnetic resonance (MR) angiography with gadodiamide and gadopentetate dimeglumine (0.1 mmol/kg), with intraarterial DSA as reference standard, for imaging abdominal and iliac arterial stenoses.

Materials And Methods: The study was approved by all institutional review boards; informed consent was obtained from each subject before procedures.

Diagnosis of IPA in HIV: the role of the chest X-ray and radiologist.

The role of clinical information and chest film for the discrimination between invasive pulmonary aspergillosis (IPA) and its differential diagnoses in human immunodeficiency virus (HIV) infection was studied. The diagnostic performance of clinical information and chest film alone and in combination was studied for eight internists and eight radiologists with regular exposure to IPA patients. The multicenter case sample consisted of 25 patients with proven IPA and 25 with other pulmonary diseases typical for HIV.

Surgical treatment of cholangiocellular carcinoma.

Cholangiocarcinoma is a primary liver tumor arising from the small bile ducts within the liver. According to its different location, clinical features, frequency of metastases, treatment modalities and prognosis, intrahepatic cholangiocarcinoma should well be differentiated from proximal bile duct carcinoma. To date, there is no therapeutic measure with curative potential apart from surgical treatment.
