Mod Pathol 2021 Jun 21. Epub 2021 Jun 21.

Experimental Cancer Genetics, Wellcome Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge, UK.

Dedifferentiation and transdifferentiation are rare and only poorly understood phenomena in cutaneous melanoma. To study this disease more comprehensively we have retrieved 11 primary cutaneous melanomas from our pathology archives showing biphasic features characterized by a conventional melanoma and additional areas of de-/trans-differentiation as defined by a lack of immunohistochemical expression of all conventional melanocytic markers (S-100 protein, SOX10, Melan-A, and HMB-45). The clinical, histologic, and immunohistochemical findings were recorded and follow-up was obtained. Read More

Political continuity or a new beginning? The re-foundation of the "German Society for Pathology" and its politics in postwar Germany.

Pathol Res Pract 2021 May 28;224:153491. Epub 2021 May 28.

Institute for History, Theory and Ethics in Medicine, Medical Faculty, RWTH Aachen University, Wendlingweg 2, 52074 Aachen, Germany. Electronic address:

In 1948, about 70 pathologists decided to reconstitute the "Deutsche Pathologische Gesellschaft" (German Pathological Society). With Arnold Lauche, a new president was elected; at the same time, the organization was renamed the "Deutsche Gesellschaft für Pathologie" (German Society of Pathology). But did these two obvious changes really mark a new beginning, a conscious turning away from the Nazi ideology that had significantly shaped the policies of the professional associations until 1945? The present paper pursues this very question. Read More

The Boltysh impact structure: An early Danian impact event during recovery from the K-Pg mass extinction.

Sci Adv 2021 Jun 18;7(25). Epub 2021 Jun 18.

Geology and Petroleum Geology, School of Geosciences, University of Aberdeen, Aberdeen, UK.

Both the Chicxulub and Boltysh impact events are associated with the K-Pg boundary. While Chicxulub is firmly linked to the end-Cretaceous mass extinction, the temporal relationship of the ~24-km-diameter Boltysh impact to these events is uncertain, although it is thought to have occurred 2 to 5 ka before the mass extinction. Here, we conduct the first direct geochronological comparison of Boltysh to the K-Pg boundary. Read More

Establishing and operating a 'virtual ward' system to provide care for patients with COVID-19 at home: experience from The Gambia.

BMJ Glob Health 2021 06;6(6)

Clinical Services Department, Medical Research Council Unit The Gambia, at London School of Hygiene and Tropical Medicine, Banjul, Gambia.

Health systems in sub-Saharan Africa have remained overstretched from dealing with endemic diseases, which limit their capacity to absorb additional stress from new and emerging infectious diseases. Against this backdrop, the rapidly evolving COVID-19 pandemic presented an additional challenge of insufficient hospital beds and human resource for health needed to deliver hospital-based COVID-19 care. Emerging evidence from high-income countries suggests that a 'virtual ward' (VW) system can provide adequate home-based care for selected patients with COVID-19, thereby reducing the need for admissions and mitigate additional stress on hospital beds.
