Influence of clinical and experimental intra-articular inflammation on neutrophil gelatinase-associated lipocalin concentrations in horses.

Objective: To investigate neutrophil gelatinase-associated lipocalin (NGAL) concentrations in serum and synovial fluid (SF) from horses with joint inflammation.

Study Design: Experimental studies and retrospective clinical study.

Sample Population: Serum and SF samples were available from healthy horses (n = 19), clinical cases, and horses with experimental joint inflammation.

Repeatability of tumor blood flow quantification with Rubidium PET/CT in prostate cancer - a test-retest study.

Background: Non-invasive tumor blood flow (TBF) quantification is a candidate approach for risk stratification and monitoring of prostate cancer patients. Validation data have recently been published on prostate TBF measurement with the widely used positron emission tomography (PET) flow tracer Rubidium (Rb). However, no test-retest data is available for TBF measurement with Rb PET in prostate cancer.

Deep Learning-Based Algorithms in Screening of Diabetic Retinopathy: A Systematic Review of Diagnostic Performance.

Topic: Diagnostic performance of deep learning-based algorithms in screening patients with diabetes for diabetic retinopathy (DR). The algorithms were compared with the current gold standard of classification by human specialists.

Clinical Relevance: Because DR is a common cause of visual impairment, screening is indicated to avoid irreversible vision loss.
