TLDR
The degradation of hydrocortisone phosphate in essentially neutral solutions appears to involve hydrolysis as the only significant degradative pathway and an equation expressing the effect of both temperature and pH on the rate of the reaction is presented.
Abstract
The degradation of hydrocortisone phosphate in essentially neutral solutions appears to involve hydrolysis as the only significant degradative pathway. The reaction is first order with respect to the steroid ester and seems linearly dependent upon the hydrogen ion concentration. The reaction is apparently an unusual 0.44 order with respect to the catalyst. The activation energy for the overall reaction has been found to be 17.0 ± 0.5 Kcal./mole. The “frequency factor” of the Arrhenius equation has been calculated and an equation expressing the effect of both temperature and pH on the rate of the reaction is presented.

Impact of disease management programs on healthcare expenditures for patients with diabetes, depression, heart failure or chronic obstructive pulmonary disease: a systematic review of the literature.

TL;DR: Although it is widely believed that disease management programs reduce healthcare expenditures, the present study shows that evidence for this claim is still inconclusive and well-designed economic evaluations should be stimulated.

A quantitative color reaction for cortisone and related 17,21-dihydroxy-20-ketosteroids

TL;DR: Another test which appears to be specific for 17,21-dihydroxy-20-ketosteroids is added, based upon the appearance of a yellow color in solutions containing the steroid, phenylhydrazine, and sulfuric acid.
