AbstractObjectiveThis study investigated the long‐term outcomes of laparascopic sigmoid cervicovaginoplasty in patients with congenital cervicovaginal atresia with a functioning uterus.MethodsIn this case series study, seven patients with cervicovaginal atresia with a functioning uterus underwent laparoscopic sigmoid cervicovaginoplasty surgery between 2016 and 2020. Mean follow‐up duration was 25.9 months (2–48 months). All of the patients had regular menstrual cycles. The average length of the vagina was 8.9 cm (7.6–10.5 cm). In one patient, proximal stenosis of neovagina was observed 12 months after surgery.ResultsThe mean age and body mass index of the patients were 18 years (12–27 years) and 19.7 (17.6–22.4), respectively. The average time period between the initiation of disease symptoms and the operation was 52.28 months (2–156 months). There were no postoperative short‐term complications. We did not perform hysterectomy in our patients. None of our patients complained of signs of low anterior resection syndrome. Two patients had sexual activities without dyspareunia, postcoital bleeding, or malodorous vaginal discharge.ConclusionSigmoid cervicovaginoplasty is a safe and effective procedure with satisfactory long‐term outcomes. This surgery eliminates the psychological burden of hysterectomy in these patients. Through preserving the uterus, patients may have a chance of possible future pregnancy if abdominal cerclage is performed.

In this paper, we completely determine the complexity for both and on general digraphs, symmetric digraphs, and Eulerian digraphs. In particular, among our results, we prove and use the NP‐completeness of 2‐linkage problem restricted to Eulerian digraphs. We also give sharp bounds and equalities for the two parameters and .

BackgroundThe Liver Imaging Reporting and Data System (LI‐RADS) is a comprehensive system for standardizing the terminology and interpretation of liver imaging. The association between the LI‐RADS category and tumor recurrence in patients with intrahepatic cholangiocarcinomas (iCCAs) has not yet been evaluated in a multicenter study.PurposeTo retrospectively investigate the preoperative clinical and imaging features associated with recurrence‐free survival (RFS) after curative resection of iCCAs and to identify the role of the LI‐RADS category in at‐risk patients.Study TypeRetrospective, multicenter.SubjectsA total of 113 patients (mean age: 61.1 years; 74 men, 39 women) who underwent preoperative contrast‐enhanced MRI and curative surgical resection for a single treatment‐naive iCCA between 2008 and 2021.Filed Strength/SequenceA 3 T dual gradient‐echo T1WI with in‐ and opposed‐phase, turbo spin‐echo T2WI, diffusion‐weighted echo‐planar images, and three‐dimensional gradient‐echo T1WI before and after administration of contrast agent.AssessmentMR imaging features were evaluated and assigned for each lesion using LI‐RADS version 2018. RFS was calculated from the date of surgery to tumor recurrence or the last imaging date without evidence of recurrence. Factors affecting RFS were evaluated using clinical and imaging features.Statistical TestsCox proportional hazards model, Kaplan–Meier method, and log‐rank test. A P‐value of <0.05 was considered statistically significant.ResultsA total of 93 (82.3%) were categorized as LR‐M and 20 (17.7%) were categorized as LR‐4 or 5. In the multivariable analysis, LR‐M category (hazard ratio [HR], 8.035; 95% confidence interval [CI], 1.096–58.931) and a tumor size >3 cm on MRI (HR, 2.690; 95% CI, 1.319–5.487) were independent factors for poor RFS. The 5‐year RFS rate was significantly higher in patients with iCCA categorized as LR‐4 or 5 than in those categorized as LR‐M (94.4% vs. 51.9%, respectively).Data ConclusionPatients with iCCA categorized as LR‐4 or 5 may have a better RFS than those categorized as LR‐M.Evidence Level3Technical EfficacyStage 2
Anodizing—The pore makes the difference
Authors: Schneider Michael , Fürbeth Wolfram 
Published: July 2022

AbstractThe presentation gives an insight into the fascinating world of anodizing as corrosion protection but also goes far beyond. Starting with an introduction to the formation of anodic oxide films and their characteristic features, the authors briefly outline the subject of pore nucleation and growth. The number, size, and shape of the pores essentially determine the properties and play a crucial role in the final application of the anodizing layers. The tailoring of pore design, considering the final application as well as the use of the porous oxide layers for subsequent functional modifications, is demonstrated by examples, exclusively developed in the working groups of the respective authors or in joint research projects, which were in part professionally accompanied and supported by the German Corrosion Society GfKORR e.V.

AbstractBackgroundTwo studies that examined the interaction betweenHLA‐DRB1and smoking in Parkinson's disease (PD) yielded findings in opposite directions.ObjectiveTo perform a large‐scale independent replication of theHLA‐DRB1 × smoking interaction.MethodsWe genotyped 182 single nucleotide polymorphism (SNPs) associated with smoking initiation in 12 424 cases and 9480 controls to perform a Mendelian randomization (MR) analysis in strata defined byHLA‐DRB1.ResultsAt the amino acid level, a valine at position 11 (V11) inHLA‐DRB1displayed the strongest association with PD. MR showed an inverse association between genetically predicted smoking initiation and PD only in absence of V11 (odds ratio, 0.74, 95% confidence interval, 0.59–0.93, PInteraction = 0.028).In silicopredictions of the influence of V11 and smoking‐induced modifications of α‐synuclein on binding affinity showed findings consistent with this interaction pattern.ConclusionsDespite being one of the most robust findings in PD research, the mechanisms underlying the inverse association between smoking and PD remain unknown. Our findings may help better understand this association. © 2022 The Authors.Movement Disorderspublished by Wiley Periodicals LLC on behalf of International Parkinson and Movement Disorder Society

Published: July 2022

ABSTRACTImportanceDuring the coronavirus disease 2019 (COVID‐19) lockdown, changes in the visiting rules in neonatal units might have affected the initiation and continuation of breastfeeding.ObjectiveTo investigate the effects of the implementation of the COVID‐19 lockdown in the UK on mother's own milk (MOM) feeding in hospital and at the time of discharge in two UK neonatal units.MethodsRetrospective cohort study using routinely recorded data from electronic patient records. Data were retrieved from two neonatal services in the UK East Midlands region. Adjusted logistic regression was used to compare the odds of MOM feeding before, and after the implementation of the UK lockdown.ResultsAmong 2073 infants, after adjusting for maternal and infant characteristics and underlying trends over time, there were no differences in the odds of infants receiving any MOM during admission; any MOM at discharge or exclusive MOM at discharge before and after the imposition of the lockdown. Infants with birthweight <1000 g were three times less likely to receive any MOM at discharge compared to those with birthweight >2500 g (adjusted odds ratio [OR] 0.33, 95% confidence interval [CI]: 0.22–0.50). Younger mothers were less likely, and Black British mothers more likely, to be feeding MOM to their infants at discharge, while women in the least deprived Index of Multiple Deprivation (IMD) quintiles were 2–4 times more likely to do so, compared to those in the most deprived IMD quintile (adjusted OR 2.78, 95% CI: 1.97–3.90).InterpretationDespite the difficulties faced during COVID‐19 pandemic‐induced restrictions, infants in the participating neonatal units continued to receive MOM in similar proportions as before the pandemic.

AbstractPoly‐m‐phenyleneisophthalamide (PMIA) with excellent chemical stability and breakdown strenth is regarded as the next generation of insulating paper in power system. However, the basic intensity of PMIA is not enough to match its operating cost, and it is promising to enhance the performance by nano composition. In this paper, the influence of nano‐TiO2ith a mass fraction of 1 to 5 wt% on insulating properties is studied, including breakdown voltage and bulk conductivity. The silane coupling agent aminopropyltriethoxysilane (APTES) together with the polydopamine (PDA) are used for modifying the fillers interface. The results show that, APTES covalent grafting and PDA physically coating can improve the dispersion and compatibility of nano‐TiO2 in aramid fiber matrix, thus regulating the interface trap characteristics and reducing the probability of electric field distortion in insulating paper. When the modified TiO2 content is 2 wt%, the breakdown voltage is the highest, which is 23.9 kV/mm, 54% higher than that of pure aramid paper. In addition, this article discusses the modification mechanism from molecular dynamic simulation and trap characteristics. Based on molecular dynamics calculation, three interface models of PMIA‐TiO2, PMIA‐TiO2/APTES, PMIA‐TiO2/APTES/PDA are constructed, and the synergistic effect of PDA is confirmed from the microscopic level.

AbstractObjectiveParental reports and brief clinical examinations are the primary information used to assist clinicians in weaning home supplemental oxygen in infants with bronchopulmonary dysplasia (BPD). Recorded nocturnal oximetry provides an objective assessment of hypoxemia; however, it is unknown if it identifies clinically undetected hypoxemia in the home setting. Our objective was to determine if nocturnal oximetry can identify unreported hypoxemia in infants with BPD who appear ready to wean from supplemental oxygen.Study DesignWe conducted a retrospective chart review of infants born <32 weeks gestation with BPD who were discharged to home receiving supplemental oxygen and completed recorded nocturnal oximetry in room air during an 18‐month period. Abnormal oximetry was defined as >5 min with SpO2 < 90% and/or an oxyhemoglobin desaturation index (ODI4) >5. Comparative analysis of patients with normal and abnormal overnight oximetry was performed using Fisher Exact and Wilcoxon signed‐rank test.ResultsThirty‐five former premature infants completed nocturnal oximetry at 5.8 (3.4−8.3) months corrected age. Nocturnal oximetry was abnormal as defined in 67% of the cohort (n = 21). Five percent of patients were hypoxemic, 52% had frequent desaturation events, and 43% had both. No significant differences existed in neonatal characteristics between patients with normal and abnormal studies.ConclusionsNocturnal oximetry was abnormal in the majority of infants with BPD who were otherwise clinically ready to wean from oxygen support, suggesting that recorded home oximetry could be a feasible and useful tool to evaluate for otherwise clinically unapparent nocturnal hypoxemia in patients with BPD.

Published: July 2022

AbstractBACKGROUNDPrevious studies have found that pesticide double‐stranded (ds)RNA usually has a long‐lasting validity period in plants. However, it is uncertain if any factors in plants could extend dsRNA duration. It has been reported that RNA‐dependent RNA polymerases (RdRP) in plants and some other eukaryotes could catalyze RNA amplification and be involved in RNAi (interference). Thus, this study evaluated the effect of RdRP on the tissue content, activity, and duration of exogenous dsRNA.RESULTSWe found that RdRP knockdown in Arabidopsis thaliana had no significant effect on tissue contents of reporter dsRNA parent molecules (8.91% reduction), but it caused significant decrease in the tissue contents of derived short fragments of 200, 120 and 59 bp tested (51.22%, 52.83% and 59.35%, respectively). Aphid inoculation tests showed that the same dose of insecticidal dsAgZFP exhibited a significantly lower lethal effect (mortality 58.8%) in the plants with RdRP knockdown than in the control plants with normal RdRP (86.0%). For Caenorhabditis elegans, the worms treated simultaneously with dsRdRP and reporter dsRNA had similar body contents to reporter dsRNA parent molecules and its long‐fragment derivative (200 bp) as the control (1.28‐ and 1.07‐fold greater, respectively). However, 120‐ and 59‐bp short‐fragment derivatives were significantly reduced by 28.78% and 59.84%, respectively, which also diminished faster in the descendants.CONCLUSIONSWe conclude that RdRP could significantly enhance the tissue content of dsRNA derivatives by catalyzing amplification, thus improving dsRNA activity and extending its lasting validity period. Otherwise, RNAi by exogenous dsRNA was proven to be noninheritable in A. thaliana. This work confirmed the merit of dsRNA as a plant protectant. © 2022 Society of Chemical Industry.
Role of Spin–Orbit Coupling on Ultrafast Spin Dynamics in Nonmagnet/Ferromagnet Heterostructures

Published: July 2022

AbstractSpin–orbit coupling (SOC), the interaction between spin and orbital angular momentum of electrons, is imperative to control magnetic properties of nonmagnet (NM)/ferromagnet (FM) heterostructures and design energy‐efficient and faster spin‐based devices. Here, femtosecond pulsed laser‐induced time‐resolved magneto‐optical Kerr effect magnetometry is employed to investigate magnetization dynamics in different NM/Co20Fe60B20 heterostructures, where the NM layer varies as Cu, Ta, W, Pt, Ta/Ru/Ta, and Si/SiO2 (no underlayer) that differ in SOC strength. It is observed that there is a systematic variation in ultrafast demagnetization time (τm), fast remagnetization time (τr), and Gilbert damping parameter (α) with the SOC strength of the underlayer and an inverse relationship between α and τm, τr is established due to the dominant contribution of spin current transport in ultrafast demagnetization and fast remagnetization processes. The spin pumping formalism estimates the effective spin‐mixing conductance (Geff) for different interfaces, which signifies that the high SOC strength of underlayers results in high Geff indicating more efficient transport of spin current through it. This study suggests that the SOC strength of the NM underlayer plays a significant role in controlling the ultrafast demagnetization process through interfacial spin current transport in a NM/FM heterostructure which can be beneficial for the development of ultrafast spintronics devices.

AbstractSolids undergoing symmetry breaking phase transitions commonly exhibit domains of low symmetry phases with various sizes and morphological shapes. Usually, the shapes of these domains are not directly related to the nature of symmetry breaking. Here, an interesting example of a layered dichalcogenide with a triangular lattice is shown, in which symmetry breaking of electronic charge/orbital is accompanied by formation of striped domains and exotic surface states with peculiar spin textures. Using angle‐resolved photoemission spectromicroscopy, the mesoscopic striped domains in the layered IrTe2 are observed across the first order phase transition at ≈280 K. Under further cooling down to 47 K, the striped domains evolve into trijunction domains with electronic anisotropy in three directions. Each domain harbors quasi 1D surface bands forming fragmented Fermi surfaces (Fermi arcs) with peculiar spin polarization revealed by spin‐resolved photoemission spectroscopy. The Fermi arc corresponds to an edge state of the 2D bulk electronic bands truncated at the surface, indicating an interesting interplay between the symmetry breaking, surface electronic structure, and the spin state.

AbstractIt is well‐established that experience with a disaster can heighten risk perception, initiate policy learning, and ultimately enhance preparedness and mitigation. This experience can make stakeholders more amenable to mitigating risk, but disasters are sporadic, dangerous, and costly. At the same time, the importance of differences in epistemic communities that manage public agencies and departments has received little attention in the context of policy learning, preparedness, and mitigation. This study investigates whether it is possible for simulated disasters, such as tabletop exercises, to influence risk perception and encourage learning in a way that is consistent with the effects of experiencing an actual disaster. To test this idea, we analyze survey data collected from an Environmental Protection Agency workshop of drinking water officials and public health stakeholders from southeast Michigan and northwest Ohio, including Detroit, Flint, and Toledo. A pre and posttest survey captured participants' beliefs before and after a tabletop exercise designed to simulate a large‐scale drinking water disaster. Results suggest that epistemic communities matter in these exercises but professional experience is less important than what previous studies have shown about experience with a policy problem and policy learning.

Published: July 2022

AbstractHalide‐free, water‐in‐salt electrolytes (WiSEs) composed of potassium acetate (KAc) and zinc acetate (ZnAc2) are investigated as electrolytes in zinc‐ion hybrid supercapacitors (ZHSs). Molecular dynamics simulations demonstrate that water molecules are mostly non‐interacting with each other in the highly concentrated WiSEs, while “bulk‐like water” regions are present in the dilute electrolyte. Among the various concentrated electrolytes investigated, the 30 m KAc and 1 m ZnAc2 electrolyte (30K1Zn) grants the best performance in terms of reversibility and stability of Zn plating/stripping while the less concentrated electrolyte cannot suppress corrosion of Zn and hydrogen evolution. The ZHSs utilizing 30K1Zn, in combination with a commercial activated carbon (AC) positive electrode and Zn as the negative electrode, deliver a capacity of 65 mAh g−1 (based on the AC weight) at a current density of 5 A g−1. They also offer an excellent capacity retention over 10 000 cycles and an impressive coulombic efficiency (≈100%).
