摘要： Purpose: We assessed the reliability and validity of an efficient severity assessment for pelvic pain and urinary symptoms in urological chronic pelvic pain syndrome, which consists of interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome. Materials and Methods: A total of 578 patients were assessed using brief, empirically derived self-report scales for pelvic pain severity (PPS) and urinary symptom severity (USS) 4 times during a 1-month period and baseline clinic visit that included urological, pain and illness-impact measures. Mild, moderate and severe categories on each dimension were examined for measurement stability and construct validity. Results: PPS and USS severity categories had adequate reliability and both discriminant validity (differential relationships with specific clinical and selfreport measures) and convergent validity (common association with nonurological somatic symptoms). For example, increasing PPS was associated with pelvic tenderness and widespread pelvic pain, whereas USS was associated with urgency during a bladder filling test and increased sensory sensitivity. PPS and USS categories were independently associated with nonurological pain and emotional distress. A descriptive analysis identified higher likelihood characteristics associated with having moderate to severe PPS or USS or both. Lack of sex interactions indicated that the measures are comparable in interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome. Conclusions: Women and men with urological chronic pelvic pain syndrome can be reliably subgrouped using brief self-report measures of mild, moderate or severe pelvic pain and urinary symptoms. Comparisons with a broad range of clinical variables demonstrate the validity and potential clinical utility of these classifications, including use in clinical trials, health services and biological research.

摘要： 又是秋来时 早上,路过巷口,一阵凉风吹来,卷起地上的片片落叶,顿时感觉冷飕飕的. "哇,真是天凉好个秋."我禁不住感叹. 几天前,我回老家收花生,就已经感觉到秋意浓浓:田埂上荒草漫过膝盖,一路上的草籽灌进鞋窝里,粘到袜子上;蜻蜓在眼前飞来晃去,大蚂蚱落在肩上;田间地头的寒豇豆饱鼓鼓地东倒西歪着??这一切把秋意渲染得铺天盖地.

摘要： This study presents an extensive plant-wide model-based assessment of four alternative activated sludge (AS) configurations for biological nitrogen (N) and phosphorus (P) removal under uncertain influent loads and characteristics. Zeekoegat wastewater treatment plant (WWTP) in South Africa was chosen as case study due to its flexible design that enables operation in four different AS configurations: 3-stage Bardenpho (A2O), University of Cape Town (UCT), UCT modified (UCTM), and Johannesburg (JHB). A metamodeling based global sensitivity analysis was performed on a steady-state plant-wide simulation model using Activated Sludge Model No. 2d with the latest extension of physico-chemical processes describing the plant-wide P transformations. The simulation results showed that the predictions of effluent chemical oxygen demand (COD), N and P using the proposed approach fall within the interquartile range of measured data. The study also revealed that process configuration can affect: 1) how influent uncertainty is reflected in model predictions for effluent quality and cost related performances, and 2) the parameter rankings based on variance decomposition, particularly for effluent phosphate, sludge disposal and methane production. The results identified UCT and UCTM as more robust configurations for P removal (less propagated uncertainty and less sensitivity to N load) in the expense of incomplete denitrification. Moreover, based on the results of Monte-Carlo based scenario analysis, the balanced SRT for N and P removal is more sensitive to influent load variation/uncertainty for the A2O and JHB configurations. This gives a more operational flexibility to UCT and UCTM, where a narrow SRT range can ensure both N and P removal.

摘要： The progression of antibiotic-resistant bacteria (ARB) as well as impaired immunity due to chronic diseases and complications, aging, and so forth pose opportunities in parallel with challenges to the wound dressing products. In a bid to address the remedies, electrospun nanofibrous membranes (ENMs) with high permeability and good biocompatibility have made an entry as wound dressings. With high specific surface area, such ENMs can pave the way for the loading and release of antimicrobial agents and further promote wound healing by mimicking the extracellular matrix structure. In this review, we have compiled a series of novel antimicrobial agents that can be substituted for antibiotics against ARB and outlined their antimicrobial mechanisms, providing an overview of the latest research to illustrate how ENMs can achieve the loading and efficient release of antimicrobial agents against ARB. Last but not least, on the basis of the demands for timely and accurate wound diagnosis, ENMs capable of colorimetric detection are featured as test-strips for the diagnosis of wound pathogenic bacteria, in the hope of inspiring researchers to design smart wound dressings capable of diagnosis and treatment integration.

摘要： Shipping is a very important source of pollution worldwide. In recent years, numerous actions and measures have been developed trying to reduce the levels of greenhouse gases (GHG) from the marine exhaust emissions in the fight against climate change, boosting the Sustainable Development Goal 13. Following this target, the action of hydrogen as energy vector makes it a suitable alternative to be used as fuel, constituting a very promising energy carrier for energy transition and decarbonization in maritime transport. The objective of this study is to develop an ex-ante environmental evaluation of two promising technologies for vessels propulsion, a H-2 Polymeric Electrolytic Membrane Fuel Cell (PEMFC), and a H-2 Internal Combustion Engine (ICE), in order to determine their viability and eligibility compared to the traditional one, a diesel ICE. The applied methodology follows the Life Cycle Assessment (LCA) guidelines, considering a functional unit of 1 kWh of energy produced. LCA results reveal that both alternatives have great potential to promote the energy transition, particularly the H-2 ICE. However, as technologies readiness level is quite low, it was concluded that the assessment has been conducted at a very early stage, so their sustainability and environmental performance may change as they become more widely developed and deployed, which can be only achieved with political and stakeholder's involvement and collaboration.
