Micro-CT gives archived prostate tissue a three-dimensional view
A five-core proof-of-concept study found that intact paraffin specimens could be scanned before histology, but clinical value remains untested.
Review outlines three routes to evidence in small populations
An overview of ICH, EMA and FDA guidance outlines ways to enlarge feasible samples, adapt study designs and use outside information, while flagging gaps in Bayesian methods and evidence synthesis.
PRAME staining linked to shorter survival in uveal melanoma
A hospital cohort found shorter survival when PRAME was assessed across whole tumour sections, but the observational design limits what the result can show.
Long-term APDS study links leniolisib to lower infection rates
An open-label extension followed 37 patients for up to seven years, reporting lower modeled infection rates and changes in immune markers without a control group.
Nursing Interns Report More Speaking Up in Better-Rated Placements
A cross-sectional survey in three Hunan teaching hospitals found statistical pathways linking internship environment, self-efficacy and professional identity with voice behavior.
Teacher-Referenced AI Tension Linked to Learning-Focused Use
A cross-sectional survey of 1,004 Chinese university students found a positive association, but could not show whether perceived tension changes AI use.
Florida interviews highlight trust in vaccine-hesitancy talks
A qualitative project with local providers and advocates shaped a practical guide, but it did not test whether the resource changes conversations or vaccination decisions.
Nasal dexmedetomidine linked to fewer lung complications after surgery
A peer-reviewed trial found fewer complications over seven days in selected older patients, but larger studies are needed in people at higher risk.
Software flags expanded T-cell clones, but small ones can be missed
The replicateFest framework was tested on synthetic experiments and a published HIV-1 T-cell receptor dataset.
PSMA PET study finds tumor volume differed between two tracers
Among 140 patients receiving radioligand therapy, SUV readings were similar, but total tumor volume was higher after Ga-68 PSMA-11 imaging.
Study links smaller colorectal tumors to higher metastasis rates
A retrospective analysis found the clearest survival gap among men aged 50 or younger with T4 disease, while external testing showed more modest predictive performance.
Second scan often changed fixed perfusion defect readings
A later thallium SPECT scan changed the classification of many low-uptake areas, but the study did not establish that heart muscle could recover.
TRIAGES score linked to poorer outcomes after brain injury
The single-hospital study found a small edge over admission GCS, while its cutoff still needs testing in other settings.
Three ABO Variants Point to One Shared Splicing Defect
A single case led to laboratory tests that found the same exon-skipping pattern in three variants, but the proposed risk map still needs broader validation.
Costa Rican hospital review finds very low survival in lung cancer
A peer-reviewed record review found long and variable care pathways, limited biomarker testing, and a five-year survival estimate of 1.9% from the first suspected-cancer care episode.
Vasopressin sped up surgery but showed no ovarian-reserve gain
A randomized trial in women with unilateral ovarian endometriomas found faster bleeding control, but no significant difference in AMH after 12 months.
Cost awareness linked to more efficient resource use at work
A survey of 246 human-service professionals in Türkiye linked perceived organizational justice to part of the relationship, but cannot show cause and effect.
AI in Health Research Is Growing Faster Than Its Audit Trail
A review finds rapid regulatory adoption and bold efficiency claims, but little public evidence showing how AI changes health-economics decisions.
Thyroid cancer model ranked risk well outside but overstated risk levels
A retrospective two-center study found strong patient ranking at an external center, but the model's absolute risk estimates ran high and need local recalibration.
