Imaging-based spatial transcriptomics (ST) is evolving rapidly as a pivotal technology in studying the biology of tumors and their associated microenvironments. However, the strengths of the commercially available ST platforms in studying spatial biology have not been systematically evaluated using rigorously controlled experiments. In this study, we used serial 5-m sections of formalin-fixed, paraffin-embedded surgically resected lung adenocarcinoma and pleural mesothelioma tumor samples in tissue microarrays to compare the performance of the single cell ST platforms CosMx, MERFISH, and Xenium (uni/multi-modal) platforms in reference to bulk RNA sequencing, multiplex immunofluorescence, GeoMx Digital Spatial Profiler, and hematoxylin and eosin staining data for the same samples.

Developed in 2011, the virtual fracture clinic (VFC) was fully implemented at an institution during the COVID-19 pandemic to reduce in-person interactions.
Aims: First, the study aims to measure the percentage of non-operative patients triaged through the VFC when this was optional and re-audit after implementing a COVID-19-related policy change mandating VFC triage.
Background: Uncomplicated urinary tract infections (uUTIs) are common bacterial infections.
Aim: Evaluate the burden of uUTI in England for 1) potential determinants of disease progression; 2) extent and impact of antimicrobial prescribing non-concordant with treatment guidelines; and 3) economic burden and costs.
Design & Setting: Retrospective cohort study utilising patient data from the Clinical Practice Research Datalink (CPRD) linked to English Hospital Episodes Statistics.
Article Synopsis
- Approximately 10% of lung adenocarcinomas (LUAD) have mucinous histology (LUADMuc), which is linked to a lighter/absent smoking history and a higher prevalence of KRAS mutations compared to LUAD without this histology (LUADnon-muc).
- A study analyzed features and treatment outcomes of LUADMuc and LUADnon-muc patients, revealing LUADMuc patients had less aggressive disease characteristics and a poorer response to current therapies, especially immunotherapy.
- Overall, LUADMuc showed lower objective response rates, shorter progression-free and overall survival compared to LUADnon-muc, highlighting a need for more effective treatment strategies for this subgroup.
Article Synopsis
- - Drug resistance in EGFR-mutant non-small cell lung cancer (NSCLC) is complicated by mechanisms like pathway reactivation and fusion of receptor tyrosine kinases (RTKs), leading to challenges in treatment with tyrosine kinase inhibitors (TKIs).
- - A study involving multiple institutions analyzed 27 patients with RTK fusions identified through genetic testing, focusing on their response to dual TKI therapy, with results showing a 24% objective response rate and an 80% disease control rate overall.
- - The majority of patients had ALK or RET fusions, and those who received dual TKI treatment had a slightly lower response rate (21.4%) but no new side effects were reported, suggesting this approach
