Rotablator-associated coronary perforation can be fatal if bailout is delayed. Successful bailout is typically defined as the disappearance of contrast extravasation after a haemostatic intervention. We report a case of recurrent cardiac tamponade in the subacute phase, wherein haemostasis appeared to have been achieved on angiography following the implantation of a covered stent during the index procedure.

Immune checkpoint inhibitors (ICIs) are effective in treating recurrent/metastatic head and neck squamous cell carcinoma (HNSCC), but only 20% of patients achieve durable responses. This study evaluated circulating tumor DNA (ctDNA) as a real-time biomarker for monitoring treatment response in HNSCC. The SHIZUKU-HN study prospectively collected and analyzed serial plasma samples (n = 27) from HNSCC patients undergoing ICIs, using Guardant360 to assess ctDNA variant allele frequency (VAF) and genetic mutations.

This paper proposes a diffusion-model-based method for addressing inverse problems in optical sound-field imaging. Optical sound-field imaging, known for its high spatial resolution, measures sound by detecting small variations in the refractive index of air caused by sound but often suffers from unavoidable noise contamination. Therefore, we present a diffusion model-based approach for sound-field inverse problems, including denoising, noisy sound-field reconstruction and extrapolation.

Insulin treatment should be introduced in patients with slowly progressive type 1 diabetes (SPIDDM; definite), according to the revised diagnostic criteria of SPIDDM (2023). In contrast, SPIDDM (probable) patients are in a non-insulin-dependent state; therefore, a more flexible treatment can be considered, although sulfonylurea agents should be avoided. Insulin treatment has been shown to maintain endogenous insulin secretion capacity in SPIDDM (probable); however, this does not mean that all SPIDDM (probable) patients should use insulin from the early phase.

Article Synopsis
  • This study analyzed how well patients with type 2 diabetes stick to their prescribed treatment of semaglutide, either in oral form (O-SEMA) or as a weekly injection (SEMA-SC), over a year.
  • The research found that patients using SEMA-SC were more likely to be non-adherent compared to those taking O-SEMA, with a significant odds ratio suggesting this trend.
  • Overall, patients on O-SEMA demonstrated better adherence and persistence with their treatment than those on SEMA-SC, indicating that oral medication may lead to earlier and more consistent GLP-1RA therapy.

Sporadic inclusion body myositis (sIBM) is a muscle disease in older people and is characterized by inflammatory cell invasion into intact muscle fibers and rimmed vacuoles. The pathomechanism of sIBM is not fully elucidated yet, and controversy exists as to whether sIBM is a primary autoimmune disease or a degenerative muscle disease with secondary inflammation. Previously, we established a method of collecting CD56-positive myoblasts from human skeletal muscle biopsy samples.

Aims: Latent autoimmune diabetes in adults (LADA) is characterized by positive islet-associated autoantibodies including glutamic acid decarboxylase antibody (GADA), and gradual decline in insulin secretion, progressing to insulin dependency. This cross-sectional study aimed to determine whether GADA by enzyme-linked immunosorbent assay (GADA-ELISA) titer of ≥180 U/mL could be associated with decline in β-cell function in participants with LADA.

Methods: Sixty-three participants with LADA were recruited and an association between insulin secretion capacity and disease duration was investigated.

While the molecular mechanism of autophagy is well studied, the cargoes delivered by autophagy remain incompletely characterized. To examine the selectivity of autophagy cargo, we conducted proteomics on isolated yeast autophagic bodies, which are intermediate structures in the autophagy process. We identify a protein, Hab1, that is highly preferentially delivered to vacuoles.

Article Synopsis
  • A 39-year-old pregnant woman developed symptoms of gestational diabetes insipidus (DI) after 31 weeks, characterized by excessive thirst and urination, leading to the suspicion of DI based on lab results.
  • Her condition worsened, resulting in acute kidney failure and an emergency cesarean section at 34 weeks, revealing a significantly enlarged placenta.
  • Post-delivery, she received a treatment that resolved her symptoms, and findings indicated that the excessive vasopressinase from the enlarged placenta, along with insufficient vasopressin from the pituitary, contributed to her DI symptoms.
