Insightec to launch new trials of Exablate Neuro
By
LabPulse.com staff writers
One study will evaluate the use of Exablate Neuro to treat patients with primary non-small cell lung cancer that has metastasized to the brain in conjunction with Keytruda, a humanized antibody immunotherapy. Exablate Neuro could be used to open up the blood-brain barrier to make immunotherapy agents like Keytruda more effective.

AI of chest x-rays finds TB when lab tests fall short
By
Leah Sherwood and Erik L. Ridley
As part of the End TB strategy, the World Health Organization (WHO) has recommended the use of chest x-ray as a screening and triage tool where bacteriological diagnostic tests are unclear. Inconclusive TB tests are common in children due to their lower bacteria counts, according to the WHO. The strategy also states that lateral chest x-ray views may be needed in cases of a challenging bacteriological confirmation in younger children.

Spinal fluid tests may aid PET scans of Alzheimer's disease
By
Will Morton
A Swiss group led by senior author Michael Schöll, PhD, of the University Gothenburg investigated whether fluid and blood biomarkers that indicate Alzheimer's disease could predict the accumulation of neurofibrillary tau tangles seen on PET scans in patients diagnosed with the disease. They found the lab tests performed well enough to help select patients for PET imaging studies evaluating new treatments.Associations of baseline beta-amyloid PET and baseline phosphorylated tau-181 (p-tau181) with F-18 flortaucipir (FTP) Standardized uptake value ratio (SUVR) annualized change for (A) cognitively unimpaired and (B) cognitively impaired individuals.

Brain surface renderings depict Pearson correlation coefficients adjusted for age and sex (r) representing the strength of the association between the different biomarkers and F-18 flortaucipir SUVR change in each brain region. The right upper panel represents age- and sex-adjusted Pearson correlation coefficients (r), along with p-values, for the association between the biomarkers and F-18 flortaucipir SUVR change in the Alzheimer's disease meta-region of interest (ROI). The root mean squared error (RMSE) for the prediction of F-18 flortaucipir SUVR change by a linear model with the biomarker as predictor and age and sex as covariates. RMSE was estimated using leave-one-out cross-validation. Voxel-wise statistical maps were thresholded using more lenient cluster-forming thresholds of p < 0.05 (uncorrected) at the voxel level and further thresholded at the cluster level by restricting results to clusters with a number of voxels higher than the expected number of voxels as predicted using random field theory.
