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.
Erythropoietin (EPO), also known as hematopoietin or hemopoietin, is a glycoprotein cytokine secreted by the kidney in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow. Low levels of EPO (around 10 mU/mL) are constantly secreted sufficient to compensate for normal red blood cell turnover.
