"Higher renal net acid, but not higher phosphate excretion during growth associates with lower adult circulating uromodulin".

Objective: Uromodulin is the most abundant urinary protein in healthy subjects which under physiological conditions protects against kidney stone formation. Acid-base imbalances, especially states with acidic urine, increase the risk for uric acid and oxalate stones, but lower it for phosphate-containing stones. Whether habitual high acid loads and high dietary phosphorus intake (P-In) themselves may influence plasma uromodulin concentrations in the long-term is not known.

Young adults' circulating FGF23 and α-klotho and their relationship with habitual dietary acid load and phosphorus intake during growth.

The bone-derived hormone FGF23, primarily secreted by osteocytes, is a major player in the regulation of phosphate homeostasis. It becomes upregulated by increased circulating phosphate concentration, e.g.

Getting breastfeeding started under pandemic visiting restrictions: lessons learned in Germany.

Background: The COVID-19 pandemic contact restrictions considerably changed maternal visiting contacts during the time in which breastfeeding is initiated. We wanted to know how maternity ward staff and mothers rated the conditions of starting breastfeeding under contact restrictions.

Methods: In the Breastfeeding in North Rhine-Westphalia (SINA) study, Germany, 2021/22, chief physicians as well as ward staff from 41 (out of 131) maternity hospitals (82 members of the healthcare sector in total) were surveyed by telephone concerning structural and practical conditions for breastfeeding support before and during the pandemic; 192 (out of 426 eligible) mothers answered an online-questionnaire about their breastfeeding experiences at 2 weeks and 2 months after birth.
