Atrial and ventricular natriuretic peptides play an important role in the neurohormonal regulation of cardiac function. Plasma levels of these peptides may aid in the diagnosis and prognosis of different cardiac disorders, such as congestive heart failure, ischemic heart disease, and atrial fibrillation. However, the association between elevated pericardial fluid levels of natriuretic peptides and these clinical conditions has not been proven.

The variability of the environmental factors to which Austrolebias annual fishes are exposed has acted as a strong selective pressure shaping traits such as nervous system plasticity. This has contributed to adaptation to their extreme conditions including the decreased luminosity as ponds dry out.

Background: The number of children requiring prolonged mechanical ventilation (PMV) has increased with the advancement of medical care. We aimed to estimate the prevalence of PMV worldwide, document demographic and clinical characteristics of children requiring PMV in paediatric intensive care units (PICUs), and to understand variation in clinical practice and health-care burden.
Methods: This international, multicentre, cross-sectional cohort study screened participating PICUs in 28 countries for children aged >37 postgestational weeks to 17 years who had been receiving mechanical ventilation (MV; invasive or non-invasive) for at least 14 consecutive days.

Human milk oligosaccharides (HMO) are the specific and selective growth substrate for bifidobacteria, preventing pathogen adhesion, modulating the immune system, and impacting neurodevelopment. Human milk is the best food for the neonate; infant formulas enriched with HMOs are indicated when human milk is not possible or sufficient. HMOs developed and added to available infant formulas are 2'-FL (2'-fucosyl lactose), 3-FL (3-fucosyl lactose), 3'-SL (3'-sialyl lactose), 6'-SL (6'-sialyl lactose), LNT (lacto-N-tetraose), and 3'-GL (3'-galactosyl lactose), the latter being produced in situ by microbial fermentation.
