As with lower respiratory infections,the rate for upper respiratory infections and otitis was estimated to belower in developed countries, at 12% (5â18%). Globally, more than 1.5million deaths annually from respiratory infections are attributable to theenvironment (see Table A2.3).ther estimates of theenvironmental attributable fraction came from the CRA (WHO, 2002). Wereport the results for each disease or disease group in the following sections. Indoor and outdoor air quality are two of the main environmental factorsof concern for acute lower respiratory infections.
Erythropoietin (EPO) is a hormone produced by the kidney that promotes the formation of red blood cells by the bone marrow.
a glycoprotein hormone secreted mainly by the kidney. A profactor, erythropoietinogen, is first produced in the liver, transferred to the kidney and converted to active erythropoietin in the kidney. The erythropoietin acts on stem cells of the bone marrow to stimulate red blood cell production (erythropoiesis). Called also erythropoietin stimulating factor, erythrogenin.
