Introduction: Patients with type 2 diabetes (T2D) undergoing dialysis exhibit a higher mortality rate compared with those with other conditions, primarily due to vascular complications including coronary artery disease, heart failure and stroke. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, a type of drug for T2D, have reportedly decreased cardiovascular and renal events in patients with heart failure and chronic kidney disease, irrespective of diabetes presence. Nevertheless, the evidence supporting the use of SGLT2 inhibitors in patients undergoing dialysis has been limited.

Prokaryotic chromosomes contain numerous small open reading frames (ORFs) of less than 200 bases. Since high-throughput proteomics methods often miss proteins containing fewer than 60 amino acids, it is difficult to decern if they encode proteins. Recent studies have revealed that many small proteins are membrane proteins with a single membrane-anchoring α-helix.

Article Synopsis
  • Fibrates can cause renal toxicity, which limits their use in patients with chronic kidney disease (CKD), but pemafibrate appears to be less harmful to kidney function.
  • A study analyzed the effects of pemafibrate on 520 diabetic participants, assessing changes in kidney function over 52 weeks across different treatment options (ADD-ON, SWITCH, CTRL).
  • Findings indicated that eGFR improved only in the SWITCH group, particularly in patients without severe kidney dysfunction, suggesting that switching to pemafibrate may benefit kidney function, but less so in patients with advanced renal issues.

Rationale: The increasing use of immune checkpoint inhibitors (ICIs) for treating malignant tumors result in the concomitant rise of immune-related adverse events (irAEs). This case report may provide useful insight to understanding the etiology of ICI-induced hypophysitis, a severe irAE leading to potentially fatal secondary adrenal insufficiency.

Patient Concerns: An 81-year-old Japanese man was hospitalized for diabetic ketoacidosis following 4 courses of ICI combination therapy with nivolumab and ipilimumab for metastatic renal cell carcinoma.

Article Synopsis
  • - The study evaluates the effectiveness of axillary ultrasound (AUS) in detecting lymph node metastasis in patients with clinically T1-2 N0 breast cancer who had negative AUS results prior to sentinel lymph node biopsy (SLNB).
  • - Out of 948 patients analyzed, the false negative rate of AUS was roughly 20%, while the rates of high nodal burden (HNB) were quite low at around 1-2%.
  • - The findings indicate that while MRI has limitations (low positive predictive value), it can effectively confirm negative AUS results with a high negative predictive value, suggesting that some cases of SLNB might be safely omitted.
