We experienced a case of a patient with a history of pacemaker implantation who was found to have lung cancer just behind the pacemaker. She was an 80-year-old woman with a history of valve replacement, pacemaker implantation, and sarcoidosis. Computed tomography showed a ground-glass opacity of 1.

Article Synopsis
  • The study compares knee biomechanics among different types of knee arthroplasty, including bicruciate-stabilized, posterior-stabilized, and unicompartmental knee replacements, along with normal knees.
  • Researchers analyzed the movements and forces exerted during walking by monitoring healthy individuals and those who had undergone the various arthroplasty procedures about 11 months post-surgery.
  • Findings revealed that the bicruciate-stabilized group had less internal rotation than the unicompartmental group, while the posterior-stabilized group showed reduced knee extension compared to the healthy control group, indicating a need for targeted rehabilitation to improve flexibility post-surgery.

With the ageing of the population in Japan, an increasing number of elderly prostate cancer patients will require treatment. However, the elderly often have comorbidities, which can make treatment decisions for prostate cancer patients difficult. Therefore, we investigated prostate cancer deaths and risk factors among patients aged 80 years or older at diagnosis of prostate cancer at our hospital.

We report a solid-acid catalyzed aminolysis of epoxides under continuous-flow conditions. A titania-zirconia supported molybdenum oxide catalyst demonstrated exceptional substrate compatibility, enabling the synthesis of β-amino alcohols in excellent yields with high catalyst durability. Characterization of the catalyst revealed the crucial role of the titania-zirconia ratio in optimizing its performance.
