Cerebral Microbleeds and Their Association With Inflammation and Blood-Brain Barrier Leakage in Small Vessel Disease.
Stroke
January 2025
Stroke Research Group, Department of Clinical Neurosciences, University of Cambridge, United Kingdom.
Background: How cerebral microbleeds (CMBs) are formed, and how they cause tissue damage is not fully understood, but it has been suggested they are associated with inflammation, and they could also be related to increased blood-brain barrier (BBB) leakage. We investigated the relationship of CMBs with inflammation and BBB leakage in cerebral small vessel disease, and in particular, whether these 2 processes were increased in the vicinity of CMBs.
Methods: In 54 patients with sporadic cerebral small vessel disease presenting with lacunar stroke, we simultaneously assessed microglial activation using the positron emission tomography ligand [11C]PK11195 and BBB leakage using dynamic contrast enhanced magnetic resonance imaging, on a positron emission tomography-magnetic resonance imaging system.
[F]FDG PET/CT for predicting neoadjuvant PD-L1 blockade monotherapy treatment response in patients with locally advanced esophageal squamous cell carcinoma: a preliminary study.
Eur J Nucl Med Mol Imaging
January 2025
Department of Nuclear Medicine, Zhongshan Hospital, Fudan University, No. 180 in Fenglin Road, Shanghai, 200032, P.R. China.
Purpose: To investigate the predictive value of 2-[18F]-fluoro-2-deoxy-D-glucose ([F]FDG) PET/CT for evaluating primary tumor (PT) and lymph node (LN) responses after neoadjuvant programmed death-ligand 1 (PD-L1) blockade monotherapy in patients with locally advanced esophageal squamous cell carcinoma (LA-ESCC).
Methods: In the single-arm phase 1b NATION-1907 trial (NCT04215471), 23 patients with LA-ESCC received two cycles of neoadjuvant PD-L1 blockade Adebrelimab followed by surgery. Among these, 18 patients underwent [F]FDG PET/CT scans both before immunotherapy and prior to surgery.

Article Synopsis
- Antibiotic resistance genes (ARGs) from gut microbiota pose significant health risks and can be influenced by non-antibiotic factors like disease states, particularly in cases of cerebral ischemia-reperfusion injury (I/R) which is common in stroke patients.
- Changes in the gut antibiotic resistome during I/R show an increase in tetracycline ARGs while other types, like aminoglycoside and glycopeptide ARGs, decrease, suggesting a shift in microbial resistance profiles.
- The study identifies specific ARG hosts and pathways influenced by I/R, highlighting the increase in multidrug resistance genes and various biosynthetic processes in gut microbiota, providing potential targets for health interventions.
Synovitis scoring in hand osteoarthritis with ultrasonography: the performance of the Global OMERACT/EULAR Ultrasound Synovitis Score (GLOESS) is comparable to synovial thickening alone.
RMD Open
December 2024
Rheumatology, Leiden University Medical Center, Leiden, Zuid-Holland, Netherlands.
Background: Inflammation is increasingly recognised as a treatment target in hand osteoarthritis, and therefore correct measurement of local inflammation is essential. This study aimed to assess ultrasound scoring of synovitis and the additional value of the Global OMERACT/EULAR Ultrasound Synovitis Score (GLOESS) in hand osteoarthritis.
Methods: Data from the randomised, double-blinded Hand Osteoarthritis Prednisolone Efficacy (HOPE) trial were used.
Matched serum- and urine-derived biomarkers of interstitial cystitis/bladder pain syndrome.
PLoS One
December 2024
Institute of Cell Biology, Faculty of Medicine, University of Ljubljana, Ljubljana, Slovenia.
Setting up the correct diagnosis of interstitial cystitis/bladder pain syndrome (IC/BPS), a chronic inflammatory disease of the bladder, is a challenge, as there are neither diagnostic criteria nor reliable and non-invasive disease biomarkers available. The aim of the present study was to simultaneously determine matched serum- and urine-derived biomarkers of IC/BPS, which would provide additional insights into disease mechanisms and set the basis for further biomarker validation. Our study included 12 female patients with IC/BPS and 12 healthy controls.
