Salt + Glycerol-Induced Hyperhydration Enhances Fluid Retention More Than Salt- or Glycerol-Induced Hyperhydration.

Hyperhydration has been demonstrated to improve work capacity and cardiovascular and thermoregulatory functions, enhance orthostatic tolerance, slow or neutralize bone demineralization, and decrease postdive bubble formation. Adding sodium or glycerol to a hyperhydration solution optimizes fluid retention. Sodium and glycerol produce their effect through different physiological mechanisms.

Temporal Trends in the Prevalence and Incidence of Diagnosed ADHD in Children and Young Adults between 1999 and 2012 in Canada: A Data Linkage Study.

Objective: There is a need for the routine monitoring of treated attention-deficit hyperactivity disorder (ADHD) for timely policy making. The objective is to report and assess over a decade the prevalence and incidence of diagnosed ADHD in Canada.

Methods: Administrative linked patient data from the provinces of Manitoba, Ontario, Quebec, and Nova Scotia were obtained from the same sources as the Canadian Chronic Diseases Surveillance Systems to assess the prevalence and incidence of a primary physician diagnosis of ADHD ( ICD-9 and ICD-10 codes: 314, F90.
