Newborn anthropometry was not associated with maternal age, educational level SCH772984 or living location.
Conclusions: Independently of gestational age and newborn sex, the main predictors of birth weight and length were maternal pre-pregnancy anthropometry and weight gain during gestation, to smoke during pregnancy, parity and maternal origin. Our results identify potential modifiable factors influencing newborn body size.”
“Background: Peritoneal dialysis (PD) is probably under-used because of fears concerning the body image of patients. For the purposes of providing exact information for patients when choosing between PD and hemodialysis, we studied the extent of increase in waist circumference by infusing
Methods: The abdominal circumference
of 44 PD patients was measured before and after infusion of dialysate. The change in circumference was compared to body mass index (BMI) and length of the abdominal cavity, defined by the distance between the processus xiphoideus and the os pubis.
Results: Mean abdominal circumferences at the umbilicus and the iliac crest increased from 92.6 +/- 10.1 to 95.5 +/- 10.0 cm and from 95.2 +/- 8.5 to 96.2 +/- 6.3 cm, respectively, when dialysate was infused (p value for both <0.01). A dialysate volume of 2000 mL increased the circumference only slightly more than the increase seen with 1500 mL. The change in circumference was not correlated with the circumference before the infusion, BMI, height of the patient, or length of the abdominal cavity.
Conclusions: This study shows that normal PD fill volumes increase the waist circumference only a little. This CBL0137 finding should ease the patient’s presumption of PD changing the body image.”
The treatment of methane in bioreactors with an aqueous phase such as biofilters is limited by low methane water solubility. In the case of biotrickling filters (BTF), the continuous trickling water is a barrier to methane transfer. In a previous study, the use of non-ionic surfactants improved the performance of biofilters treating methane. RESULTS: Three BTFs treating methane were operated for 1 year under fixed operating conditions of methane concentration of 4.8 g m-3 and air flow rate of 0.25 m-3 WH-4-023 h-1. Three kinds of packing material were tested and a non-ionic surfactant (Brij 35) was periodically added to the nutrient solution at a concentration of 0.5% w/w. Methane conversion was a function of the type of packing materials and the presence of Brij 35 in the nutrient solution. When Brij 35 was added, the methane conversion doubled with respect to the BTFs without surfactant. CONCLUSION: The addition of Brij 35 to the nutrient solution increased the performance of the BTF for the three packing materials tested. The non-ionic surfactant also affected the carbon dioxide production. The BTFs were stable when the packed bed was washed to remove the excess of biomass.
