Influenza in Adults Seeking Care at Seven European Emergency Departments: A Prospective Active Surveillance During the 2019-2020 Influenza Season.

Background: Influenza can be associated with nonrespiratory disease presentation, but these are less well documented due to the lack of routine testing for influenza in the healthcare system, especially if patients do not present with influenza-like illness (ILI). We aimed to measure the proportion of influenza cases seeking care at emergency department (ED) for a nontraumatic cause, to describe their clinical presentation and their ED-discharge diagnosis.

Methods: The study was conducted at seven hospitals in France, Spain, Italy and Germany during the 2019-20 influenza season, for a period of 10 weeks.

Fixed Subluxation of the Distal Radioulnar Joint following Malunion of the Ulnar Styloid Process.

 Recent literature on significance and treatment of ulnar styloid fractures suggest that the ulnar styloid is not the central problem but the radioulnar ligaments and their impact on joint stability. However, specifically displaced ulnar styloid process fractures that secondarily heal in an ectopic position remain a rare situation for which diagnostics and treatment options remain a topic of discussion.  This case series presents four patients with limited supination due to a fixed dorsal subluxation of the distal radioulnar joint (DRUJ).

Cement Spacer Formed in a 3D-Printed Mold for Endoprosthetic Reconstruction of an Infected Sarcomatous Radius: A Case Report.

Case: The ulcerated recurrent clear cell sarcoma of the forearm with bony invasion of the radius needed an uncontaminated resection and control of infection. A mold was printed based on CT-reconstructed 3D models of the patient's anatomy to create an antibiotic-loaded cement spacer as endoprosthetic replacement used in combination with soft-tissue reconstruction and systemic antibiotics.

Conclusion: This then undescribed novel technique allowed for fast local recovery of the patient's hand function and return to work.

Ecological opportunity shapes a large Arctic charr species radiation.

Ecological opportunity is considered a crucial factor for adaptive radiation. Here, we combine genetic, morphological and ecological data to assess species and ecomorphological diversity of Artic charr in six lakes of a catchment in southernmost Greenland, where only charr and stickleback occur. Because the diversity of habitats and resources increases with lake size, we predict a positive association between lake size and the extent of ecomorphological diversity.

Arrival order and release from competition does not explain why haplochromine cichlids radiated in Lake Victoria.

The frequent occurrence of adaptive radiations on oceanic islands and in lakes is often attributed to ecological opportunity resulting from release from competition where arrival order among lineages predicts which lineage radiates. This occurs when the lineage that arrives first expands its niche breadth and diversifies into a set of ecological specialists with associated monopolization of the resources. Later-arriving species do not experience ecological opportunity and do not radiate.
