Aim: Increased arterial stiffness impairs the functional and structural properties of arteries, which in turn elevates blood pressure (BP). The aim of this study was to test whether indices obtained from the second derivative of the finger photoplethysmogram (SDPTG), a marker of arterial stiffness, predict future development of hypertension in middle-aged men.

Methods: The SDPTG was measured in 902 men without hypertension (mean age 44±6 years) at an annual medical checkup.

Article Synopsis
  • - Heart failure can reduce blood flow to the brain, potentially affecting recovery after mechanical thrombectomy (MT) in stroke patients, and this study examined the relationship between brain natriuretic peptide (BNP) levels and recovery outcomes.
  • - Data from 169 stroke patients showed that those with favorable outcomes (score of 0-2 on the modified Rankin scale at 3 months) had lower median BNP levels compared to those with unfavorable outcomes, suggesting that higher BNP levels are linked to poorer recovery.
  • - The analysis indicated that patients with BNP levels above 186 pg/mL had a significantly lower rate of favorable outcomes, even when considering other factors like atrial fibrillation, reinforcing the idea that high BNP concentration correlates with

  • A phase 3 trial evaluated the effectiveness of adding a CTLA-4 inhibitor to standard platinum-based chemotherapy and PD-1/PD-L1 inhibitors for patients with advanced non-small-cell lung cancer, as no prior studies had focused on this combination's survival benefits.
  • Conducted across 48 hospitals in Japan, the trial involved patients aged 20+ with untreated NSCLC, but had to stop recruitment early due to a concerning number of treatment-related deaths in the nivolumab-ipilimumab group.
  • The final results indicated no significant difference in overall survival between those receiving pembrolizumab and those receiving nivolumab-ipilimumab, with median survival rates of 23.7 months and 20.5

Total Nail Avulsion for Pincer Nail: Report of Two Cases.

Plast Reconstr Surg Glob Open

August 2024

Department of Dermatology, Nippon Medical School, Tokyo, Japan.

Pincer nail is a common condition characterized by excessive transverse curvature of the nail that causes pain, cosmetic problems, and functional limitation. Surgical treatments include correction of the nail bed and distal phalanges, which have shown good outcomes but are difficult to perform in general clinics because of their high invasion. Conservative treatments require special devices, which may be difficult to keep on hand in general clinics.

Int J Hematol

October 2024

Department of Hematology, Nippon Medical School, Sendagi 1-1-5, Bunkyo-ku, Tokyo, 113-8603, Japan.

Germline (GL) predisposition to acute myeloid leukemia (AML) has been established as an independent disease entity in the latest World Health Organization classification. Following the American College of Medical Genetics and Genomics guidelines, GL variants were interpreted as causal if they were classified as "pathogenic." GL predisposition can be divided into three groups with different phenotypes, and play an important role in the pathogenesis of adult-onset AML.

Out-of-hospital cardiac arrest (OHCA) is a global public health problem, with survival rates remaining low at around 10% or less despite widespread cardiopulmonary resuscitation (CPR) training and availability of automated external defibrillators (AEDs). This is partly due to the challenges of knowing when and where a sudden OHCA occurs and where the nearest AED is located. In response, countries around the world have begun to use network technology-based smartphone applications.

Article Synopsis
  • The All Nippon Atrial Fibrillation In the Elderly Registry studied over 30,000 elderly Japanese patients with non-valvular atrial fibrillation, focusing on outcomes based on age and type of oral anticoagulants (OACs).
  • Results showed that the incidence of stroke, major bleeding, and intracranial hemorrhage increased significantly with age, but plateaued for those aged 90 and over.
  • Direct OACs (DOACs) generally resulted in lower event rates compared to warfarin, particularly in patients aged 75-85 years, but had limited effectiveness in reducing major bleeding for patients aged 90 and older, suggesting very-low-dose DOACs might be beneficial for this older
