: Janus kinase (JAK) inhibitors have emerged as a new class of disease-modifying anti-rheumatic drugs in the treatment of rheumatoid arthritis (RA). However, herpes zoster is one of the common adverse events of JAK inhibitors, including upadacitinib, which is especially high in Japanese patients with RA compared to those from Western countries. Recombinant zoster vaccine (Shingrix) is an adjuvanted subunit vaccine containing varicella-zoster virus (VZV) glycoprotein E (gE) that is effective in adults over 50 years of age.

  • The study aimed to compare postoperative pain levels between robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in lung cancer patients and investigate how port number or placement affects pain.
  • After analyzing data from 405 patients, it was found that RATS had a higher average number of ports and greater operation time compared to VATS, but RATS did not show a significant increase in pain risk according to multivariable analysis.
  • Overall, the results suggested that RATS is potentially worse than VATS regarding postoperative pain due to its longer operation times and more local anesthesia used, but it didn't demonstrate noninferiority in pain outcomes.

Background: In assessing the effects of smoking cessation on endothelial function, low-flow-mediated constriction (L-FMC) may provide complementary information to flow-mediated dilation (FMD). However, the value of flow-mediated total dilation (FMTD), an index that incorporates L-FMC into FMD, remains underreported. We aimed to evaluate the effect of smoking cessation on endothelial function, as assessed by FMD and FMTD, and clarify its associated clinical factors.

Upper tract urothelial carcinoma (UTUC) is a rare form of urothelial cancer with a high incidence of recurrence and a low survival rate. Almost two-thirds of UTUCs are invasive at the time of diagnosis; therefore, improving diagnostic methods is key to increasing survival rates. Histopathological analysis of UTUC is essential for diagnosis and typically requires endoscopy biopsy, tissue sectioning, and labeling.

The varicella-zoster virus (VZV) is a human neurotropic herpes virus responsible for varicella and herpes zoster (HZ). Following primary infection in childhood, VZV manifests as varicella (chickenpox) and enters a period of latency within the dorsal root ganglion. A compromised cellular immune response due to aging or immunosuppression triggers viral reactivation and the development of HZ (shingles).

  • A recent study explored the use of serum growth differentiation factor-15 (GDF15) as a biomarker to identify high-risk patients with metabolic dysfunction-associated steatotic liver disease (MASLD) who need closer follow-up for liver cancer.
  • Researchers analyzed GDF15 levels in over 500 MASLD patients and found that high levels were linked to increased liver cancer risk, regardless of fibrosis stage or standard risk indicators like the Fib-4 index.
  • The findings suggest that GDF15 could be a convenient and effective indicator for determining which MASLD patients should undergo regular monitoring for liver cancer, thus potentially improving patient outcomes.
