Article Synopsis
  • Vascular endothelial growth factor (VEGF) is important in kidney health as it helps with blood vessel growth and permeability, but blocking it can impede tumor growth.
  • A study in Taiwan using extensive health data showed that patients treated with the anti-VEGF drug bevacizumab had a significantly higher risk of developing chronic kidney disease (CKD) compared to those who weren't treated.
  • The research highlights the need for careful monitoring of kidney function in patients receiving bevacizumab, as the risk of CKD was found to be 1.35 times greater in these patients.

Rheumatoid arthritis (RA), a chronic inflammatory disease, carries a significant burden of atherosclerotic cardiovascular diseases (ASCVD). With their heterogeneous composition, high-density lipoprotein (HDL) particles have varied athero-protective properties, and some may even increase ASCVD risk. In this prospective and cross-sectional study, we aimed to examine the relationship between HDL sizes/metabolites and inflammation in RA.

The intravoxel incoherent motion (IVIM) model may enhance the clinical value of multiparametric magnetic resonance imaging (mpMRI) in the detection of prostate cancer (PCa). However, while past IVIM modeling studies have shown promise, they have also reported inconsistent results and limitations, underscoring the need to further enhance the accuracy of IVIM modeling for PCa detection. Therefore, this study utilized the control point registration toolbox function in MATLAB to fuse T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) MRI images with whole-mount pathology specimen images in order to eliminate potential bias in IVIM calculations.

Whether meconium-stained amniotic fluid (MSAF) serves as an indicator of fetal distress is under debate; however, the presence of MSAF concerns both obstetricians and pediatricians because meconium aspiration is a major contributor to neonatal morbidity and mortality, even with appropriate treatment. The present study suggested that thick meconium in infants might be associated with poor outcomes compared with thin meconium based on chart reviews. In addition, cell survival assays following the incubation of various meconium concentrations with monolayers of human epithelial and embryonic lung fibroblast cell lines were consistent with the results obtained from chart reviews.

Article Synopsis
  • A nationwide study in Taiwan explored the link between air pollution and sudden sensorineural hearing loss (SSNHL), finding that this association is not widely discussed in existing literature.
  • The study tracked individuals over 12 years for SSNHL, monitoring exposure to pollutants like CO and NO, and utilized a robust statistical model to estimate risk levels.
  • Results indicated that higher long-term exposure to certain air pollutants significantly increased the risk of developing SSNHL, highlighting the need for more research to confirm these findings.
