Mapping the developmental trajectory of human astrocytes reveals divergence in glioblastoma.

Glioblastoma (GBM) is defined by heterogeneous and resilient cell populations that closely reflect neurodevelopmental cell types. Although it is clear that GBM echoes early and immature cell states, identifying the specific developmental programmes disrupted in these tumours has been hindered by a lack of high-resolution trajectories of glial and neuronal lineages. Here we delineate the course of human astrocyte maturation to uncover discrete developmental stages and attributes mirrored by GBM.

Congress of Neurological Surgeons systematic review and evidence based guideline on neuropathology for WHO grade II diffuse glioma: update.

Unlabelled: QUESTIONS AND RECOMMENDATIONS FROM THE PRIOR VERSION OF THESE GUIDELINES WITHOUT CHANGE: TARGET POPULATION: Adult patients (age ≥ 18 years) who have suspected low-grade diffuse glioma.

Question: What are the optimal neuropathological techniques to diagnose low-grade diffuse glioma in the adult?

Recommendation: Level I Histopathological analysis of a representative surgical sample of the lesion should be used to provide the diagnosis of low-grade diffuse glioma. Level III Both frozen section and cytopathologic/smear evaluation should be used to aid the intra-operative assessment of low-grade diffuse glioma diagnosis.

Label- and slide-free tissue histology using 3D epi-mode quantitative phase imaging and virtual hematoxylin and eosin staining.

Histological staining of tissue biopsies, especially hematoxylin and eosin (H&E) staining, serves as the benchmark for disease diagnosis and comprehensive clinical assessment of tissue. However, the typical formalin-fixation, paraffin-embedding (FFPE) process is laborious and time consuming, often limiting its usage in time-sensitive applications such as surgical margin assessment. To address these challenges, we combine an emerging 3D quantitative phase imaging technology, termed quantitative oblique back illumination microscopy (qOBM), with an unsupervised generative adversarial network pipeline to map qOBM phase images of unaltered thick tissues (i.

Perceptions of Delayed Alopecia Among Breast Cancer Survivors.

Background: Retrospective studies suggest that some breast cancer survivors report treatment-associated hair loss or thinning years after their diagnosis. This study investigates frequency and perceptions of alopecia persisting 6 years after patients' breast cancer diagnoses.

Methods: Breast cancer survivors participating in the Mayo Clinic Breast Disease Registry (MCBDR) were mailed a survey 6 years after diagnosis.

Exploring Rapid Response Team Activation Impact in Patients with Cirrhosis with Acute Decompensation.

Background: Cirrhosis is associated with significant healthcare utilization, yet data about in-hospital decompensations remain sparse. Additionally, the impact of liver transplant candidacy status on resuscitation and outcomes is largely unknown.

Aims: We aimed to evaluate the characteristics of resuscitation events for patients with cirrhosis with acute decompensation, analyzing liver transplant candidacy and intensive care unit (ICU) transfer parameters.
