Prevalence and determinants of burnout among physical and occupational therapists.

It is generally speculated that the ongoing changes in the health care system may increase the incidence of burnout among health care providers. The purposes of this cross-sectional study were to determine (1) the prevalence of burnout among physical therapists (PTs) and occupational therapists (OTs), (2) sociodemographic and work-related factors associated with emotional exhaustion (EE), depersonalization (DP), and personal achievement (PA) traits of PTs and OTs. In fall 1998, 169 PTs and 138 OTs employed in various clinical settings in New York City completed the survey.

Why do children become vitamin A deficient?

Vitamin A deficiency is very prevalent and contributes substantially to morbidity and mortality among young children in developing countries. We identify and quantify three causes of vitamin A deficiency in young children based on data available in the literature: maternal vitamin A deficiency resulting in low concentrations of vitamin A in breast milk, inadequate dietary intake of vitamin A during and after weaning and prevalent illness. We developed a set of recursive equations to estimate the amount of vitamin A in the liver as a function of age over the first 2 y of life.
