Meetings premature criticism

The utilities check is used to verify that the utility supplied fulfills the chamber requirements as specified by the manufacturer. During IQ, the as found parameters are verified against the as specified parameters on the checklist. If the as found results are significantly different from the as specified parameters, it will be necessary to determine the cause of this discrepancy and to implement corrective actions. The utilities check is a part of the site preparation for the installation of the chamber and should include verification of the power supply, such as the voltage, amperage, and wire size and the quality, pressure, and flow rate of the feed water supply. The quality of the feed water supply is a critical component of proper operation of the chamber. Experience has shown that if the quality of the feed water does not meet the manufacturer s specifications, this will lead to premature corrosion within the humidification and/or dehumidification system and subsequent problems with maintaining the humidity in the chamber within the specified limits. 

In July 2000, a US Government panel finished a two-year study at a meeting in which it expressed serious concern that di(2-ethylhexyl) phthalate (DEHP) in PVC medical devices may harm the reproductive organs of critically ill and premature male infants exposed during medical treatment. This article reports fully on the panel s findings. 

L-Methionine (Met) conversion to Cys is impaired under stress, such as in premature infants or AIDS patients. Thus, the metabolic flow through the trans-sulphuration pathway may be inadequate to meet the Cys demand under critical conditions.
