Population-based study of a free rubella-specific antibody testing and immunization campaign in Chiba city in response to the 2018-2019 nationwide rubella outbreak in Japan.

Japan has not been able to eliminate rubella; as a result, the large rubella epidemic has occurred. Considering the complicated history of the vaccine policy in Japan, some susceptible populations became infected with rubella, resulting in an outbreak. We conducted a large serosurveillance against rubella in Chiba city after initiating free rubella-specific antibody testing and an immunization campaign during 2018-2019.

Drinking hydrogen water enhances endurance and relieves psychometric fatigue: a randomized, double-blind, placebo-controlled study .

Acute physical exercise increases reactive oxygen species in skeletal muscle, leading to tissue damage and fatigue. Molecular hydrogen (H) acts as a therapeutic antioxidant directly or indirectly by inducing antioxidative enzymes. Here, we examined the effects of drinking H water (H-infused water) on psychometric fatigue and endurance capacity in a randomized, double-blind, placebo-controlled fashion.

Granulocyte colony-stimulating factor-producing lung cancer and acute respiratory distress syndrome.

Granulocyte colony-stimulating factor (G-CSF)-producing lung cancers are known to cause extreme leukocytosis. However, acute respiratory distress syndrome (ARDS) caused by G-CSF-producing lung cancer is extremely rare. We present a case of G-CSF-producing lung cancer with marked leukocytosis, which rapidly led to severe ARDS after the patient developed pneumonia.
