Inappropriate prescribing (IP) is a common and serious global healthcare problem in elderly people, leading to increased risk of adverse drug reactions (ADRs), polypharmacy being the main risk factor for both IP and ADRs. IP in older people is highly prevalent but preventable; hence screening tools for IP have been devised, principally Beers' Criteria and the Inappropriate Prescribing in the El...

Hyponatremia is a marker of different underlying diseases and it can be a cause of morbidity itself; this implies the importance of a correct approach to the problem. The syndrome of inappropriate antidiuresis (SIAD) is one of the most common causes of hyponatremia: it is a disorder of sodium and water balance characterized by urinary dilution impairment and hypotonic hyponatremia, in the absen...

Testosterone (T) secretion declines in the aging male, albeit for unknown reasons. From an ensemble perspective, repeated incremental signaling among gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), and T is required to maintain physiological androgen availability. Pattern-regularity statistics, such as univariate approximate entropy (ApEn) and bivariate cross-ApEn, provide spec...

The syndrome of inappropriate secretion of TSH was the term originally coined to indicate two forms of central hyperthyroidism, i.e. thyrotropin (TSH)-secreting pituitary adenomas (TSHomas) and resistance to thyroid hormone action (RTH). Both forms are characterized by high levels of free thyroxine (FT4) and free triiodothyronine (FT3) in the presence of measurable TSH concentrations, a biochem...

Effects of environmental enrichment at different stages of life on stress physiology of pigs were investigated in a trial with 63 groups, each of four siblings. In each of the three growing phases (suckling 0 to 4 weeks of age, nursery 5 to 9 weeks, fattening 10 to 24 weeks) pens either were (=E) or were not (=0) enriched. Accordingly, the treatments were (i) 000, (ii) E00, (iii) EE0, (iv) 00E,...
