Adeel Khan and co-workers study anticoagulant prescriptions and survival outcomes in patients with cancer-associated venous thromboembolism.
Large data sets comprising diagnoses about chronic conditions are becoming increasingly available for research purposes. In Germany, it is planned that aggregated claims data including medical diagnoses from the statutory health insurance with roughly 70 million insurants will be published on a regular basis. Validity of the diagnoses in such big data sets can hardly be assessed. In case the data set comprises prevalence, incidence and mortality, it is possible to estimate the proportion of false positive diagnoses using mathematical relations from the illness-death model. We apply the method ...
A new study demonstrates that AI can detect and grade PCa in biopsies in a manner comparable to pathologists.
During a cruise from October to November 2019 along the West Antarctic Peninsula between 64.32ºS and 68.37ºS, we assessed the diversity and composition of the active microbial eukaryotic community within three size fractions: micro- (>20µm), nano- (20-5µm), and pico-size fractions (5-0.2µm). The communities and the environmental parameters displayed latitudinal gradients, and we observed a strong similarity in the microbial eukaryotic communities as well as the environmental parameters, between the sub-surface and the deep chlorophyll maximum (DCM) depths. Chlorophy...
Whale populations recovering from historical whaling are particularly vulnerable to incidental mortality and disturbance caused by growing ocean industrialization. Several distinct populations of rorqual whales (including humpback, blue, and fin whales) migrate and feed off the coast of Oregon, USA where spatial overlap with human activities are on the rise. Effective mitigation of conflicts requires better foundational understanding of spatial and temporal habitat use patterns to inform conservation management. Based on a year-round, multi-platform distance sampling dataset (2016-2021, 177 su...
