“Novel biodegradable poly(carbonate-ether)s (PCEs) with lower critical solution temperature (LCST) SBC-115076 chemical structure at body temperature were synthesized by copolymerization of CO2 and ethylene oxide (EO) under double metal cyanide (DMC) catalyst. The PCEs showed carbonate unit (CU) content of 1.042.4 mol % and molecular weight of 2.7247 kg/mol, which exhibited reversible thermoresponsive feature in deionized water with LCST in a broad window from 21.5 to 84.1 degrees C. The LCST was highly sensitive

to the CU content and the molecular weight of PCEs, and it showed a linear relation with CU content for PCEs with similar molecular weight. In particular, aqueous solution of PCE with a 26.0 VX-680 clinical trial mol % of CU showed an LCST around 36.1 degrees

C, which was very close to the body temperature. Interestingly, it was found that the phase transition behavior changed with PCE concentration. For PCE with Mn of 2.7 kg/mol and CU content of 30.0 mol %, the LCST increased from 21.5 to 36.7 degrees C when the PCE concentration changed from 10 to 1 g/L. Dynamic light scattering indicated that the phase transition was possibly due to a coil-to-globule transition. The thermoresponsive biodegradable PCE with LCST at body temperature is promising for biomedical applications, especially for in vivo applications. (c) 2012 Wiley Periodicals, Inc.

“Background: Retinopathy of prematurity(ROP) is the most common serious ophthalmic disease in preterm infants. Human milk may provide a protective effect for ROP; however, beneficial effects of human milk preclude

randomized trials. Therefore, we conducted a retrospective analysis comparing early postnatal nutrition with ROP development.\n\nObjective: Evaluate relationship between early postnatal nutriture and ROP surgery.\n\nDesign/methods: Nutrition data was collected for inborn AGA infants, BW 700-1000g. ROP surgery was the primary outcome variable. A single pediatric ophthalmologist supervised examinations. All infants received triweekly IM vitamin A as chronic lung disease prophylaxis (Tyson: NEJM, 1999).\n\nResults: BW and gestational age were 867 +/- 85 g and 26.3 +/- 1.2 weeks (n=77, mean +/- 1SD). ROP surgery infants(n = 11) received more parenteral nutrition, 1648 mL, and less human milk, 13.8 mL/kg-day, and vitamin E, 1.4 mg/kg-day, during the second postnatal week. Human milk was a negative predictor for ROP surgery, odds ratio = 0.94. Both groups met vitamin A recommendations; however, 74% was administered via IM injections. Neither group met vitamin E recommendations.\n\nConclusions: Human milk feeding, parenteral nutrition volume and vitamin E intake were predictors for ROP surgery. IM vitamin A injections provided the majority of vitamin A; vitamin E administration was insufficient.
