[Heart catheterization in newborn and young infants. Description of the method].
The data of 343 newborns and young infants were reviewed who, from 1968 until August 1982, had undergone heart catheterization. Variations in frequency of catheterization and diagnoses as well as lethality were investigated. The first rise of heart catheterization performances could be noted in the years of 1968 and 1969 (by routine application of the Rashkind procedure), another remarkable rise took place in the years from 1971 to 1975, probably due to better feasibilities of modern cardiac surgery. Later on, a new dynamic plateau was developed. With the utilization of echocardiography, a significant decrease of heart catheterization performances in certain diagnostic groups (HLH, PFC) was registered. Nowadays, however, new diagnostic challenges (infants with low gestational age, respiratory problems,TOKYO -- As the digital age gives people fewer reasons to use paper, the material has nevertheless found itself in the global spotlight.

Earlier this month more than 180 countries agreed to tougher rules for shipping non-recyclable plastic waste across national borders. This means more countries like Japan, the world's second-biggest producer per capita of plastic waste after the U.S., will have to deal with their non-recyclables at home instead of shipping it to other countries.

It is a welcome shift for Japan's paper industry, which has faced steadily shrinking demand. According to the Japan Paper Association, domestic demand shrank to 14.69 million tons in 2017 from 16.59 million tons in 2011. Manufacturers are now coming up with new ways to supplant plastic products in everything from straws to shampoo
