Outbreak of severe community-acquired bacterial infections among children in North Rhine-Westphalia (Germany), October to December 2022.

Purpose: In late 2022, a surge of severe S. pyogenes infections was reported in several European countries. This study assessed hospitalizations and disease severity of community-acquired bacterial infections with S.

Effects of grazing allowance and system on the use of corn-crop residues by gestating beef cows.

Duplicate fields of corn-crop residues were grazed by 3- to 11-yr-old Charolais x Angus and Charolais x Angus x Simmental cows (average BW = 630 kg) in midgestation at allowances of .41, .82, and 1.

Divalent ions and myocardial function during cardiopulmonary by-pass (CPB). Changes of total calcium, ionized calcium, and magnesium in plasma.

In 17 patients who underwent openheart surgery with cardiopulmonary bypass using heparinized fresh blood for priming the heart-lung machine the following investigations were done: Blood samples taken at different periods of surgery were assayed for total calcium (Catot), ionized calcium (Ca++), magnesium (Mg), hemoglobin, total pasma proteins, and the acid-base-status. Considering the different kinds of cardiopulmonary bypass the patients were divided into three groups: In the first group the results ofsurgical procedure with and without hemodilution perfusion were compared. During hemodilution perfusion Catot decreased markedly whereas Ca++ remained nearly constant.

Dailysate calcium and plasma calcium fractions during and after haemodialysis.

Dialysate calcium and plasma calcium fractions during and after haemodialysis: The effect of differenct dialysate Ca concentrations on the plasma Ca fractions was examined in 28 patients. In 10 patients dialysed with a dialysate Ca concentration of 3.0 mEq/l the Ca fractions were determined at the start and end of dialysis.
