The present article revisits the theoretical model of schizophrenia by Hiroshi YASUNAGA (1929-2011). Yasunaga restated ego disturbance in schizophrenia as the "Pattern Reversal" between selfhood and otherness, based on British philosopher Wauchope's concept of "pattern." This concept is meant as asymmetrical relatedness (A/B) within a pair of concepts, such as life and death, quality and quantity, and self and other, prioritizing the former (A side) over the latter (B side).

Vaccines for tetanus prevention have rapidly progressed, and the number of outbreaks, especially the incidence of tetanus in developed countries, has decreased dramatically. However, the mortality rate associated with severe tetanus remains high. Tetanus eradication is difficult owing to the widespread presence of the spores of tetanus bacteria in the environment, but tetanus can be prevented by acquired immunity from vaccines.

Article Synopsis
  • A follow-up survey conducted in 2022 assessed radiation protection practices among medical staff in endoscopy-fluoroscopy departments in Japan, following a 2020 study that reported low protective equipment usage and insufficient knowledge.
  • The survey included 464 participants, with high lead apron usage (98%) but much lower rates for other gear like thyroid collars (27%) and lead glasses (35%), indicating limited improvement since the 2020 survey.
  • While many staff attended radiation protection lectures (76%) and were aware of key concepts such as cancer risk related to radiation exposure, knowledge about specific dosage limits and diagnostic reference levels remained low, signaling further educational needs.

Rivaroxaban, a direct oral anticoagulant, is used as a first-line treatment to prevent venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE). However, whether 21 days is optimal for the initial treatment duration has not been investigated. In this subanalysis of the prospective multicenter observational J'xactly study, which included 1,039 Japanese patients with acute symptomatic/asymptomatic DVT/PE who were prescribed rivaroxaban, the VTE recurrence rate and incidence of bleeding complications were assessed in 667 patients who underwent intensive rivaroxaban treatment (15 mg, twice daily) for a short (1-8 days), intermediate (9-16), or standard (17-24) duration.

  • Osteopenia, a condition with low bone mineral density, significantly impacts survival and recovery in gastric cancer patients after gastrectomy, as shown in a study of 224 patients.
  • Out of these, 30% had osteopenia, which correlated with worse overall survival, longer hospital stays, and more complications post-surgery compared to those without it.
  • The findings suggest that preoperative osteopenia is a key predictor for poorer outcomes and potential recurrence in gastric cancer patients undergoing surgical treatment.

Article Synopsis
  • Cell transplantation using mesenchymal stromal cells (MSCs) shows potential for repairing intervertebral discs (IVDs) but faces issues such as needle-related damage and low nutrient availability.
  • A study using female rats tested MSC transplantation into vertebrae next to healthy or damaged IVDs, measuring disc height and tissue integrity over time. Results indicated that MSCs led to better maintenance of disc height and overall integrity compared to saline treatments.
  • The findings suggest that transplanting MSCs vertebrally improves IVD repair by leveraging natural cell migration, making it a potentially effective alternative to direct disc injections for addressing disc degeneration.

Understanding the expected efficacy and safety of a new regenerative therapy requires analysis of the fate of the transplanted cell graft. We have shown that transplantation of autologous cultured nasal epithelial cell sheets onto the middle ear mucosa can improve middle ear aeration and hearing. However, it remains unknown whether cultured nasal epithelial cell sheets have the potential to gain mucociliary function in the environment of the middle ear because sampling cell sheets after transplantation is challenging.
