SARS-CoV-2 lateral flow assays for possible use in national covid-19 seroprevalence surveys (React 2): diagnostic accuracy study.
(2021-03-02)
Objective To evaluate the performance of new lateral flow immunoassays (LFIAs) suitable for use in a national coronavirus disease 2019 (covid-19) seroprevalence programme (real time assessment of community transmission ...
Prevalence of antibody positivity to SARS-CoV-2 following the first peak of infection in England: Serial cross-sectional studies of 365,000 adults.
(2021-05-02)
Background The time-concentrated nature of the first wave of the COVID-19 epidemic in England in March and April 2020 provides a natural experiment to measure changes in antibody positivity at the population level before ...
DNA methylation patterns identify subgroups of pancreatic neuroendocrine tumors with clinical association.
(2021-02-03)
Here we report the DNA methylation profile of 84 sporadic pancreatic neuroendocrine tumors (PanNETs) with associated clinical and genomic information. We identified three subgroups of PanNETs, termed T1, T2 and T3, with ...
Patient positioning and immobilization procedures for hybrid MR-Linac systems.
(2021-09-20)
Hybrid magnetic resonance (MR)-guided linear accelerators represent a new horizon in the field of radiation oncology. By harnessing the favorable combination of on-board MR-imaging with the possibility to daily recalculate ...
Clinical activity of ripretinib in patients with advanced gastrointestinal stromal tumor harboring heterogenous KIT/PDGFRA mutations in the phase 3 INVICTUS study.
(2021-09-09)
Purpose Most patients with gastrointestinal stromal tumor (GIST) have activating mutations in KIT/PDGFRA and are initially responsive to tyrosine kinase inhibitors (TKIs). The acquisition of secondary mutations leads to ...
Diagnostic accuracy of deep learning in medical imaging: a systematic review and meta-analysis.
(2021-04-07)
Deep learning (DL) has the potential to transform medical diagnostics. However, the diagnostic accuracy of DL is uncertain. Our aim was to evaluate the diagnostic accuracy of DL algorithms to identify pathology in medical ...
Sequential afatinib and osimertinib in patients with EGFR mutation-positive NSCLC and acquired T790M: A global non-interventional study (UpSwinG).
(2021-09-21)
Background Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are standard of care for EGFR mutation-positive non-small cell lung cancer (NSCLC). However, optimal sequence of treatment has yet to be ...
Correlative serum biomarker analyses in the phase 2 trial of lenvatinib-plus-everolimus in patients with metastatic renal cell carcinoma.
(2021-01)
Background No biomarkers have been established to predict treatment efficacy in renal cell carcinoma (RCC). In an exploratory retrospective analysis of a Phase 2 study, we constructed composite biomarker scores (CBSs) to ...
Prospective Evaluation of Doxorubicin Cardiotoxicity in Patients with Advanced Soft-tissue Sarcoma Treated in the ANNOUNCE Phase III Randomized Trial.
(2021-02-25)
Purpose Few prospective studies have assessed anthracycline-associated cardiotoxicity in patients with sarcoma. We evaluated cardiotoxicity in patients with soft-tissue sarcomas administered doxorubicin in the phase III ...
SARS-CoV-2 detection by a clinical diagnostic RT-LAMP assay
(F1000 Research Ltd, 2021-01-21)
The ongoing pandemic of SARS-CoV-2 calls for rapid and cost-effective methods to accurately identify infected individuals. The vast majority of patient samples is assessed for viral RNA presence by RT-qPCR. Our biomedical ...
