In eight regional core centers for liver disease management, we evaluated the status of HBs antigen (HBsAg) and anti-hepatitis C virus antibody (anti-HCV) testing from 2016 to 2020. Among nonhepatology departments, ophthalmology had the highest number of HBsAg and anti-HCV tests, followed by obstetrics and gynecology, and orthopedics. The highest positive rates of HBsAg were in orthopedics (1.27%), gastroenterological surgery (1.23%), and ophthalmology (1.04%), and those of anti-HCV were in gastroenterological surgery (2.71%), orthopedics (2.57%), and ophthalmology (2.51%). Thus, ophthalmology and orthopedics obtained the highest number of tests and positive rates, with no rate decrease over time. While the Japan Ophthalmologists Association has already commercialized measures against hepatitis, similar measures are needed urgently in orthopedics.

Hepatitis medical care coordinators (HMCCs) in Japan are trained by local governments and regional core centers, and are expected to play an active role in various aspects of hepatitis countermeasures. A 2019 survey revealed varied activity statuses of HMCCs among facilities. This study surveyed the present status of HMCCs in 21 of the 72 regional core centers in the fiscal year 2021.A total of 951 HMCCs were trained at these 21 facilities. The 17 participating centers of the 2019 survey indicated a slight increase in the proportion of HMCCs who actively contributed to hepatitis patient care, from 84.2% to 85.8%.Despite the COVID-19 pandemic, HMCCs remained active in many facilities.

Synthesis of dense composite materials with the compositions of Al<SUB>2</SUB>O<SUB>3</SUB>/Mo<SUB>2</SUB>N=100/0∼40/60 vol% has been attempted directly from Al<SUB>2</SUB>O<SUB>3</SUB>/Mo mixed raw powder compacts using capsule-free N<SUB>2</SUB> hot isostatic pressing (HIP). During HIPing [1500°C/(16∼20-200MPa)/1h], solid/gas reaction between Mo and N<SUB>2</SUB> was introduced to form Mo<SUB>2</SUB>N. The most of sintered composites consisting of only Al<SUB>2</SUB>O<SUB>3</SUB> and Mo<SUB>2</SUB>N phases reached to a higher relative density than 98.0 % with closed pores nevertheless capsule-free HIPing. Dispersion of Mo<SUB>2</SUB>N particles just formed suppressed the grain growth of Al<SUB>2</SUB>O<SUB>3</SUB> during sintering. Mechanical properties, such as bending strength (<I>σ</I><SUB>b</SUB>), Vickers hardness (<I>H</I><SUB>V</SUB>), fracture toughness (<I>K</I><SUB>1C</SUB>), and other properties have been evaluated as a function of their compositions. The best mechanical values of <I>σ</I><SUB>b</SUB> (∼573 MPa), <I>H</I><SUB>V</SUB> (∼20.3 GPa) and <I>K</I><SUB>1C</SUB> (∼5.00 MPa·m<SUP>1/2</SUP>) were attained at the composition of Al<SUB>2</SUB>O<SUB>3</SUB>/Mo<SUB>2</SUB>N=90/10 vol%, due to a high density (98.6 %) and small grain size of Al<SUB>2</SUB>O<SUB>3</SUB> matrix (<I>G</I><SUB>s</SUB>∼4.70 <I>μ</I>m). Further addition of Mo<SUB>2</SUB>N reduced the sinterability of matrix grains, resulting in low densities of around 90 % at the 40/60 vol% composition.
