MAIN OUTCOME MEASURES Composite adverse perinatal outcome, defined as perinatal death, caesarean section for fetal distress or neonatal unit admission. RESULTS Adverse outcomes occurred in 3423 (18%) patients. The model with UA PI alone resulted in an AUC of 0.775 (95% CI 0.709-0.828) and with CPR alone in an AUC of 0.778 (95% CI 0.715-0.831). Addition of CPR to the UA PI model resulted in an increase in the AUC of 0.003 points (0.778, 95% CI 0.714-0.831). These results were consistent across all subgroups. CONCLUSIONS CPR added no predictive value for adverse perinatal outcome beyond UA PI, when assessing singleton pregnancies, irrespective of gestational age or fetal size.

Application of the thermal hydrolysis process (THP) prior to AD results in several benefits in AD and dewatering. However, soluble recalcitrant compounds associated with Maillard reactions have been identified after THP which can impact downstream processes and water discharge limits. In this study, the soluble colloidal chemical oxygen demand, color, ultraviolet absorbance at 254 nm and dissolved organic nitrogen in seven full-scale THP facilities were quantified and compared. The THP substrate influenced the concentration of soluble melanoidin-associated compounds in the digestates. THP implementation in five water resource recovery facilities (WRRFs) was modelled and found to give a 3-8 mg/L increase on the water effluent COD concentration depending on the PS/WAS ratio. The results provide novel information useful in planning new WRRFs and optimization of existing facilities. This article is protected by copyright.

Herein, an ionic exchange strategy is developed to fabricate atomically dispersed copper (Cu) catalysts with controllable coordination structure. In this process, the adsorbed Cu ions exchange with Zn nodes in ZIF-8 under high temperature, resulting in the trapping of Cu atoms within the cavities of the metal-organic framework, and thus forming Cu single-atom catalysts. More importantly, altering pyrolysis temperature can effectively control the structure of active metal center at atomic level. Specifically, higher treatment temperature (900 °C) leads to unsaturated Cu-nitrogen architecture (CuN3 moieties) in atomically dispersed Cu catalysts. Electrochemical test indicates atomically dispersed Cu catalysts with CuN3 moieties possess superior oxygen reduction reaction performance than that with higher Cu-nitrogen coordination number (CuN4 moieties), with a higher half-wave potential of 180 mV and the 10 times turnover frequency than that of CuN4 . Density functional theory calculation analysis further shows that the low N coordination number of Cu single-atom catalysts (CuN3 ) is favorable for the formation of O2 * intermediate, and thus boosts the oxygen reduction reaction. © 2020 WILEY-VCH Verlag GmbH & Co.

We experienced a case of complete rupture of an unscarred uterus that was undetected for 9 days. We report the clinical course and possible factors that led to it. Nine days after delivery, complete rupture of the posterior uterine wall was diagnosed by magnetic resonance imaging. The colon and ovaries were tightly adhered to the posterior uterine body. selleckchem When this adhesive lesion was detached, 7 cm horizontal defects of the muscular layer were revealed. The ruptured wound was repaired. Magnetic resonance imaging 1 year postoperatively showed no thinning of the repaired lesion and suggested successful reperfusion. Mild clinical course despite compl
