Consistency evaluation of Liferiver,Yaneng, Darui,and the Cobas 4800 test for high-risk human papillomavirus screening

BackgroundIn recent years, several high‐risk human papillomavirus (HR‐HPV) tests have been developed. The assay capabilities need to be systematically reviewed. Here, we compared the clinical sample performance of three novel HR‐HPV assays (Liferiver, Yaneng, and Darui) based on different platforms with the widely adopted cobas4800 test.MethodsA total of 346 cervical swabs from women who were screened for cervical cancer were analyzed for the presence of 14 HR‐HPV genotypes. The distinction between the four assays was investigated by the genotyping and direct sequencing.ResultsThe positive rates of the four assays ranged from 61.56% to 64.16%. The overall concordance was 88.15%. The Yaneng assays displayed the best sensitivity (100%) and specificity (98.43%). The sensitivity (98.17%) and specificity (98.43%) of the Darui assay were superior to those of the cobas4800 test (97.72% and 93.70%, respectively). The Liferiver assay displayed comparable sensitivity with the cobas4800 test (95.89% and 97.72%, respectively). The specificity of the cobas4800 was lower than that of the Liferiver assay (93.70% vs. 97.64%).ConclusionsThe three novel HR‐HPV assays displayed good agreement with the cobas4800 test. The analytical performance of all four fulfilled the requirements of sensitivity and specificity for HR‐HPV detection.

Current apparent treatment‐resistant hypertension in patients undergoing peritoneal dialysis: A multi‐center cross‐sectional study

Apparent treatment‐resistant hypertension (aTRH) is the most commonly used term to report resistant hypertension (RH) and is considered as a common problem in dialysis population. However, few reports have focused on peritoneal dialysis (PD) hypertensive patients. The authors conducted a multi‐center cross‐sectional study involving 1789 PD patients from nine centers in Guangdong, China. The prevalence of aTRH was estimated by home blood pressure (BP) monitoring. Evaluating drug adherence through Eight‐item Morisky Medication Adherence Scale (MMAS‐8) and pill counting was performed to assess RH in one PD center. Related factors of aTRH were analyzed using logistic regression analysis. The prevalence of aTRH in PD patients was estimated at 42.2% (755 out of 1789 hypertensive patients) based on home BP. Of those, 91.4% patients were classified as uncontrolled RH, 2.0% as controlled RH, and 6.6% as refractory hypertension. The prevalence of RH was 40.6% and 41.9% among those with medium/high adherence based on the MMAS‐8 scores and the pill counting rate, respectively. PD patients who were younger, with higher body mass index, with lower serum albumin and poorer dialysis adequacy were significantly associated with higher aTRH incident. In conclusion, the present study demonstrates a high prevalence of aTRH in PD population, which occurs in about two in five treated hypertensive patients. Nutritional status and dialysis adequacy might tightly associate with aTRH.

Effect of Radiofrequency Plasma Spheroidization Treatment on the Laser Directed Energy Deposited Properties of Low-Cost Hydrogenated-Dehydrogenated Titanium Powder

Titanium for additive manufacturing presents a challenge in the control of costs in the fabrication of products with expanding applications compared with cast titanium. In this study, hydrogenated–dehydrogenated (HDH) titanium powder with a low cost was employed to produce spherical Ti powder using the radiofrequency plasma (RF) technique. The spherical Ti powder was used as the raw material for laser directed energy deposition (LDED) to produce commercially pure titanium (CP-Ti). Microstructural analyses of the powder revealed that RF treatment, not only optimized the shape of the titanium powder, but also benefited in the removal of the residual hydride phase of the powder. Furthermore, the LDED-HDH-RF-produced samples showed an excellent combination of tensile strength and tensile ductility compared to the cast and the LDED-HDH-produced samples. Such an enhancement in the mechanical properties was attributed to the refinement of the α grain size and the dense microstructure. The present work provides an approach for LDED-produced CP-Ti to address the economic and mechanical properties of the materials, while also providing insights into the expanding application of HDH titanium powder.     

Evaporation behavior of 233Pa in FLiBeZr molten salt

In thorium molten salt reactors (TMSR), ²³³Pa is an important intermediate nuclide in the conversion chain of ²³²Th to ²³³U, its timely separation from the fuel salt is critically important for both the thorium–uranium (Th–U) fuel cycle and the neutron economy of the reactor. In this study, the evaporation behavior of ²³³Pa in the FLiBeZr molten salt was investigated during a vacuum distillation process. The separation characteristics between ²³³Pa and the major components of the fuel (salt and fission products) were evaluated in a calculation of the separation factors between these components. It was found that ²³³Pa⁵⁺ evaporated more readily than ²³³Pa⁴⁺ and the other components of the fuel, the relatively low temperature and medium pressure were much more beneficial to the separation of ²³³Pa⁵⁺ from FLiBeZr salt in the evaporation process, with the maximum value of the separation factor achieving more than 10². Results of distillation experiments also show that increasing the temperature and decreasing the ambient pressure enhances the separation between ²³³Pa⁵⁺ and most of the fission product nuclides due to the ²³³Pa⁵⁺ volatility more strongly depending on the process conditions. These results will be utilized to design a concept for a process for ²³³Pa separation from the fuel of a molten salt reactor.
