Background: Pharyngeal and anorectal reservoirs of gonorrhea(GC) and chlamydia(CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease(STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.S. ***: We recruited servicewomen stationed in San Diego, California, between the ages of 18 and 25 who presented for an annual physical exam between January and September, 2017. Nucleic acid amplification testing was performed on swabs collected at endocervical, oropharyngeal and anorectal sites to assess the presence of GC/CT. An anonymous behavioral questionnaire was also administered to characterize sexual risk. Descriptive statistics were used to compare women with and without a prior history of any sexually transmitted infection(STI)(self-report) along with a current GC/CT diagnosis. This study was approved by the Institutional Review Board of the Uniformed Services University of Health ***: Of the 75 patients who were approached, 60 subjects were enrolled in the study, including white 20(33.3%), black/African American 18(31.0%), Hispanic/Latina 13(21.7%) and Asian/Pacific Islander 9(15.5%) women. Among all the women, six(10.0%) were diagnosed with CT infection, all via endocervical exam. Of these, five(8.3%) had concurrent anorectal infection, including two cases(3.3%) accompanied by pharyngeal infection. Of the subjects, 15(25.0%) reported anal intercourse in their most recent sexual encounter, most of which was condomless(13/15, 86.7%). A high number of women who reported sex with a casual male partner(19/45, 42.2%) reported rarely or never using condoms;last, 41.7% consuming at least 3 drinks on a typical drinking day, and one-third of the reported drinking more than once

石油基聚合物的降解以及其火安全性能是当今世界面临的关键挑战。这是由于石油基聚合物应用广泛,在使用后难以降解,会导致严重的环境污染问题。此外,石油基聚合物大多易燃,易引发火灾对人类的生命安全造成威胁。因此解决这些问题显得相当紧迫,需要我们提出能够同时平衡材料环保与阻燃性能的创新解决方案。对于聚合物的降解问题,一种潜在的解决方案是利用和开发同时具有生物安全性和可生物降解的生物基聚合物。然而,相较于石油基聚合物,这些替代品往往在某些方面有性能缺陷（如力学性能et al）。因此,对这些生物基聚合物的研究需要同时兼顾其环境友好的优点并改善其对应性能的缺陷。而在阻燃性能方面,传统的阻燃剂（如含卤阻燃剂）,已被证明具有良好的阻燃效果,但由于其会产生毒副产物,存在环境与健康隐患,因此将开发新型安全无卤的磷系阻燃剂以代替传统的卤系阻燃剂。本研究通过将聚多巴胺（PDA）和磷系阻燃剂应用在聚乳酸（PLA）无纺布,为解决上述问题做出了一定贡献。通过实验发现,PDA涂层与磷系化合物的同时应用可显著提高PLA织物的阻燃性能,且涂层同样具有较高的生物安全性且对环境影响较小。此外,这项工作还凸现了PDA涂层可在PLA中快速高效应用的潜力。主要成果如下:本论文的第一部分是聚多巴胺和磷基化合物THPO作为关键阻燃剂的应用。通过喷雾共沉积方法将THPO引入到聚多巴胺基质中。这种方法显著增强了涂层织物的耐火性。极限氧指数（LOI）从对照织物的18%增加到27.5%。此外,UL-94测试的损坏长度从9.5厘米减少到7.5厘米。值得注意的是,熔体滴落性能得到增强,在测试过程中没有观察到火焰滴落。此外,热重分析显示THPO促进了适度的炭形成。仅存在聚多巴胺涂层时,样品的总烟雾产生量和烟雾产生速率均显着降低,导致Fig RA值从22.2 k W/m2s降低至14.7 k W/m2s;进一步凸显了该方法的有效性。抗紫外线测试显示,20小时内涂层样品的质量平均损失1.5%,而对照PLA织物的质量损失超过15%。本研究的第二部分重点是使用聚多巴胺作为功能涂层和聚磷酸铵（APP）作为磷基阻燃剂,在PLA织物表面形成称为PDA-Cu-APP的金属络合物。这种创新方法证明了进一步增强了织物的耐火性能,熔体滴落性能得到改善,在UL-94垂直燃烧测试中未观察到熔滴。极限氧指数（LOI）从对照PLA的18%显着增加至29.2%。此外,热重分析表明,炭残留物从对照PLA织物的1.5%增加到9.0%。Fig RA值从22.2 k W/m2s降低至14.7 k W/m2s,降低了33%。涂层中的PDA组分显着提高了抗紫外线性能,降低了质量损失率,紫外老化后涂层织物的拉伸强度是对照PLA织物的4倍。总之,本研究将生物基聚多巴胺涂层与磷基阻燃剂相结合以增强PLA织物的防火安全性,保持了环境可持续性目标的可行性。这些发现为未来开发生物基聚合物材料阻燃解决方案的研究提供了有效的途径。

BACKGROUND:Patients who present to the emergency department(ED)for suspected pulmonary embolism(PE)are often on active oral anticoagulation(AC).However,the diagnostic yield of computed tomography pulmonary angiography(CTPA)in screening for PE in patients who present on AC has not been well *** aim to investigate the diagnostic yield of CTPA in diagnosing PE depending on AC ***:We reviewed and analyzed the electronic medical records of patients who underwent CTPA for PE at a university hospital ED from June 1,2019,to March 25,*** outcome was the incidence of PE on CTPA depending on baseline AC status and indication for ***:Of 2,846 patients,242 were on AC for a history of venous thromboembolism(VTE),210 were on AC for other indications,and 2,394 were not on *** incidence of PE on CTPA was significantly lower in patients on AC for other indications(5.7%)when compared to patients on AC for prior VTE(24.3%)and patients not on AC at presentation(9.8%)(P<0.001).In multivariable analysis among the whole cohort,AC was associated with a positive CTPA(odds ratio[OR]0.26,95%confidence interval[CI]:0.15-0.45,P<0.001).CONCLUSION:The incidence of PE among patients undergoing CTPA in the ED is lower in patients previously on AC for indications other than VTE when compared to those not on AC or those on AC for history of *** status and indication for AC may affect pre-test probability of a positive CTPA,and AC status therefore warrants consideration as part of future diagnostic algorithms among patients with suspected PE.

Progressive neuroblastomas(pNBs)that defy current intensive multimodal clinical therapy(IMCT)are a significant contributor to overall childhood cancer deaths[l].Neuroblastomas(NBs)that survive first-line IMCT actively evolve to acquire genetic and molecular rearrangements and display unparalleled plasticity and evolution,which causes frequent relapses in a rapidly accelerating timeline[2-4].
