“…This discrepancy could be due to differences in the implementation of the surveillance programs. In addition, we believe that a plausible reason for the obviously increased frequencies of premature birth/low birth weight in 2015 is the increased average age of pregnancy due to the previous one-child family planning policy in China that changed to a two-child policy in the 2014–2015 period [ 12 ].…”

BackgroundWe sought to describe the epidemiological characteristics of pregnant women with syphilis in Beijing, China, and to investigate the determinants of adverse pregnancy outcomes, including congenital syphilis.Material/MethodsWe used data from laboratory-confirmed syphilis-infected women who delivered between 2013 and 2015 and were registered in China’s Information Management System for Prevention of Mother-to-Child Transmission of Syphilis. Sociodemographic, clinical, and prevention predictors of adverse pregnancy outcomes (i.e., congenital syphilis, neonatal death, and neonatal asphyxia) were assessed using multivariable regression analyses.ResultsAmong 807 eligible pregnant women with syphilis in Beijing, the maternal syphilis ratios increased from 1.1 (in 2013) to 1.4 (in 2015) per 1000 live births, while adverse pregnancy outcomes decreased, including congenital syphilis (1.3% to 0.4%), neonatal deaths (1.3% to 0%), and neonatal asphyxia (0.9% to 0%). Both prevention and treatment interventions increased, including antenatal testing (93.5% to 93.9%), any treatment (76.6% to 85.2%), adequate treatment (51.1% to 65.1%), and treatment initiated in the first trimester (30.7% to 42.8%). In the logistic regression analysis, higher maternal rapid plasma reagin antibody titers (aOR=1.1 95%CI=1.0–1.1) and third-trimester syphilis diagnosis (aOR=1.7 95%CI=1.1–2.6) were independent risk factors for adverse pregnancy outcomes. Protective factors included being married (aOR=0.4; 95%CI=0.2–0.6) and adequate prenatal treatment (aOR=0.3; 95%CI=0.1–0.7).ConclusionsIntegrated strategies for maternal syphilis control were associated with improved outcomes but must be strengthened. Future efforts should include education and outreach for antenatal care for at-risk women, syphilis screening at first antenatal care visit, immediate initiation of treatment, and syphilis screening extended to women presenting with miscarriage or stillbirth.

“…Even at an ultrahigh power density of 45 kW kg −1 , the AHESD can still deliver an energy density of 37 Wh kg −1 , higher than the values of most previ-ously reported anion rocking chair type hybrid cells of the same type (Table S4, Supporting Information). [57][58][59][60][61][62][63] In addition, NiCo-LDH//Fe─Se─NRs/GOs AHESD exhibits excellent electrochemical performance at high mass load (Figure S24, Supporting Information). In Figure 6h, the NiCo-LDH//Fe─Se─NRs/GOs AH-ESD exhibits remarkable cycling stability, maintaining 100% capacitance even after 40 000 cycles at a high current density of 10 A g −1 .…”

The introduction of battery‐type cathode has been commonly considered a preferred approach to boost the energy density of aqueous hybrid energy storage devices (AHESDs) in alkalic systems, but AHESDs with both high energy density and power density are rare due to the great challenge in designing battery‐type anode materials with high rate and durability comparable to capacitive‐type carbon anodes. In this paper, a well‐hydrated iron selenate (FeSeO) sheath is constructed around FeOOH nanorods by a facile electrochemical activation, demonstrating the unique multifunction in fasting charge diffusion, promoting the dissociation of H2O, and inhibiting the irreversible phase transition of FeOOH to inert γ‐Fe2O3, which endow the hydrated sheath coated Fe‐based anodes with an impressive rate capability and superior durability. Thanks to the comprehensive performance of this Fe‐based anode, the assembled AHESD delivered a high energy density of 117 Wh kg−1 with the extraordinary durability of almost 100% capacity retention after 40 000 cycles. Even at an ultrahigh power density of 27 000 W kg−1, an impressive energy density of 65 Wh kg−1 can be achieved, which rivals previously reported energy‐storage devices.

“…Minima of intermediates and transition states for tentative pathways were fully optimized using the hybrid B3LYP functional 50,51 coupled with the 6-311G+(d,p). 52 However, while the suitability of the B3LYP functional has been questioned, it has, in many cases, been found reliable for theoretical calculations [53][54][55][56] and prediction of organic reaction mechanisms. 57 Thus, for comparison, additional calculations were carried out for some minima and their intermediate transition states using the aug-cc-pVTZ 58 basis sets.…”
