Osteonecrosis of the jaw (ONJ) is a severe disease leading to decreased quality of life, but risk factors for ONJ in chronic kidney disease (CKD) patients remain unclear. We conducted a nested case-control study using a large Japanese administrative database to investigate. CKD patients were identified based on estimated glomerular filtration rate (eGFR) measurements, and ONJ cases were identified using ICD-10 codes and diagnostic terms.

Article Synopsis
  • Elderly patients often face feeding and swallowing issues, leading to the use of the simple suspension method where tablets are dissolved in warm water for tube administration without crushing.
  • A study using verapamil revealed that drug release was faster from crushed tablets than from the simple suspension or intact tablets, indicating significant differences in dissolution profiles.
  • While both crushing and simple suspension methods can safely help patients with dysphagia, they may also increase the risk of side effects, so it's advisable to avoid altering medications before giving them.

Article Synopsis
  • Natural killer group 2 member D ligands (NKG2DLs) in cancer cells can either activate immune responses or help tumors evade them, depending on their levels in the cells.
  • In pancreatic cancer cells (PANC-1), soluble MICB (sMICB) is found in the culture supernatant, which may saturate NKG2D T cells and inhibit their activation by membrane-bound MICB (mMICB).
  • Inhibiting the enzyme ADAM17, which contributes to the shedding of MICB, can help maintain mMICB expression and enhance NKG2D T cell activation, demonstrating a potential strategy to improve anti-tumor immune responses.

Article Synopsis
  • The use of food thickeners with ciprofloxacin can alter the drug’s appearance and slow down its dissolution, potentially affecting its effectiveness and posing economic concerns in healthcare.
  • A study was conducted on healthy Japanese males to compare how different methods of taking ciprofloxacin (with water, thickened water, and crushed tablets in thickened water) affect drug absorption.
  • Results showed that while thickened water changed drug absorption, crushed tablets in thickened water provided similar absorption metrics as tablets with regular water, though crushing may risk losing active ingredients and requires careful consideration.

Background/aim: The combination of venetoclax (VEN) and azacitidine (AZA) (VEN+AZA) leads to higher complete remission rates and longer overall survival (OS) in patients with untreated acute myeloid leukemia (AML) who are ineligible for intensive combination chemotherapy. In practice, the doses of VEN and AZA are reduced at the attending physician's discretion to avoid adverse events; however, the impact of dose and duration reductions has not been fully clarified. We analyzed whether the efficacy was maintained with reduced VEN+AZA compared to AZA monotherapy in the real world.

Prednisolone is a frequently prescribed steroid with a bitter, unpalatable taste that can result in treatment refusal. Oral suspensions or powder dosage forms are often prescribed, particularly to pediatric patients, as they improve swallowability and ease of dose adjustment. Consequently, the bitterness of prednisolone is more apparent in these dosage forms.

Two liquid crystalline polymers containing an azobenzene or cyanobiphenyl mesogenic side chain that adopt smectic A phases are mechanically mixed at 1:1 mesogen molar ratio at an isotropic phase temperature and then cooled. The resultant binary polymer mixture behaves like a single component as revealed by polarized microscopy observation and differential scanning calorimetry, indicating that the binary mixture forms a fully compatible polymer blend. Moreover, the simple polymer blend unexpectedly leads to a higher-ordered smectic E phase where a herringbone structure is formed with restricted mesogen axis rotation.
