Texas has the highest age-adjusted incidence rate of hepatocellular carcinoma (HCC) in the United States. The Cancer Prevention and Research Institute of Texas has funded the Texas Collaborative Center for Hepatocellular Cancer (TeCH) to facilitate HCC research, education, and advocacy activities with the overall goal of reducing HCC mortality in Texas through coordination, collaboration, and advocacy. On September 17, 2022, TeCH co-sponsored a multi-stakeholder conference on HCC with the Baker Institute Center for Health and Biosciences. This conference was attended by HCC researchers, policy makers, payers, members from pharmaceutical industry and patient advocacy groups in and outside of Texas. This report summarizes the results of the conference. The goal of this meeting was to identify different strategies for preventing HCC and evaluate their readiness for implementation. We call for a statewide (1) viral hepatitis elimination program; (2) program to increase nonalcoholic steatohepatitis and obesity awareness; (3) research program to develop health care models that integrate alcohol associated liver disease treatment and treatment for alcohol use disorder; and (4) demonstration projects to evaluate the effectiveness of identifying and linking patient with advanced fibrosis and cirrhosis to clinical care.

This bibliographic analysis was designed to review all dental publications in the Kingdom of Saudi Arabia (KSA) and evaluate the effect of international collaboration on the impact of published articles. The Web of Science (WOS) database was used to extract all related published articles in the KSA from 1982 to 2021. The keywords were connected using Boolean Operators to download related articles. Downloaded articles were screened according to the following inclusion criteria: collaboration journal category, journal discipline, number of citations, number of authors, and impact factor. After applying the inclusion criteria and excluding single-author articles, 5,689 documents were included in the final analysis. The chi-square test and two-independent samples t -test were used to determine the statistical significance between the variables. A significantly higher proportion of articles with international collaboration (51.4%) were published in dental journals than those published nationally (43.3%) or within the institutional level (41.8%) (P < 0.0001). In addition, the average number of citations (9.28 ± 23.8) ranged from 0 to 749, received by an article and the impact factor of the journal in which the article was published, significantly higher in the case of internationally collaborative work compared with national or within institutional collaboration (P < 0.0001). International collaboration positively affected the impact factor, number of citations, and quartile rank of published articles. Moreover, the number of co-authors in different countries contributes to the international collaboration effect. [ABSTRACT FROM AUTHOR]

• Water retention curves (WRCs) of municipal solid wastes (MSWs) • Hysteresis of WRCs of MSWs with decomposition. • Effects of decomposition and paper content on the WRCs. • Unsaturated hydraulic and gas conductivity of MSWs. This paper investigates the drying and wetting water retention curves (WRCs) of municipal solid wastes (MSWs) with different paper contents, dry unit weights and degrees of biodegradation (DOBs). Fresh synthetic samples were prepared based on the field composition of the MSWs at Mugga Lane Landfill, the Australian Capital Territory (ACT), Australia. The degraded samples were prepared in simulators with MSWs of different initial dry unit weights and decomposition periods with leachate recirculation. The water retention curves (WRCs) of the MSWs were determined using pressure plate tests, in both drying and wetting phases. The outflow from MSWs was analysed using Gardner's method to obtain the unsaturated hydraulic conductivity. The results indicate that the WRCs of the MSWs are greatly affected by the DOB, paper content and dry unit weight. When DOB < 30 %, as DOB increases, the air-entry pressure of MSWs with paper increases, and the residual moisture content decreases regardless of paper content. With DOB > 30 %, the air entry pressure and residual water content depend on the balance between organic matter and highly decomposed organic constituents. The paper content affects the WRCs of MSWs due to its water retention capacity and change in the particle size distribution with decomposition. The increase in the dry unit weight of MSWs significantly increases the air entry pressure and residual moisture content, similar to the borehole samples with combined effects of biodegradation and increase in stress level from literature. Hysteresis effects have been observed during the drying and wetting of MSWs. The hysteresis of WRCs increases with the paper content and DOB. [ABSTRACT FROM AUTHOR]

Persulfate is a potential oxidant in direct liquid fuel cells (DLFCs), and the commercial carbon paper (CP) can directly serve as the cathode due to strong oxidizability of persulfate. However, the poor catalytic activity and low specific surface area of CP limit the electrode performance. Herein, a defect-enriched, pyridine-N-dominated and self-standing carbon paper electrode with abundant carbon nanosheets is successfully prepared by hydrothermal treatment combined with in-situ electrochemical exfoliation. Benefitting from the integrated structure, plentiful defects and high-content pyridine-N dopants of the prepared electrode result in the superior electrocatalytic activity and long-term stability in persulfate reduction reaction. Remarkably, a membraneless DLFC with the prepared electrode as cathode and persulfate as the oxidant acquires prominent cell performance and extremely high open circuit voltage of 2.13 V. The maximum power density of the DLFC achieves 241.0 mW cm−2, far higher than those of the previously reported similar membraneless DLFCs. A three-dimensional computational model for the DLFC is developed, which is help to reveal the importance of improving the reaction kinetics and electrical conductivity for the cathode with persulfate as oxidant. A facile approach for in-situ preparation of highly N-doped CP electrode is provided to yield outstanding cell performance for low-cost DLFCs. [Display omitted] • A facile way to introduce high-content nitrogen on carbon paper is proposed. • Massive defective sites, carbon nanosheets and pyridine-N dopants are introduced. • N doping enhances charge transfer and electrocatalytic activity of the electrode. • Effects of hydrothermal duration and precursor concentration are discussed. • The N-doped cathode yields the outstanding cell performance for low-cost DLFC.

With the rapid development of the automotive industry, people have put forward higher requirements for automotive air filter paper, hoping that it can meet the more complex air environment. Therefore, there is an urgent need to develop "green" multifunctional air filters with excellent filtration efficiency, flame retardancy, hydrophobicity, antibacterial properties and low cost. In this work, a multifunctional cellulose-based air filter paper with flame retardant, antibacterial and hydrophobic properties was prepared from mercerized pulp and softwood pulp via chemical treatment with pre-synthesized N, N -biguanide-diethyl phosphonic acid (AGDEPA) and octadecyl trichlorosilane (OTS). Due to the high nitrogen and phosphorus content of AGDEPA, the air filter paper shows remarkable self-extinguishing behavior and have no afterglow with an intact textile structure. The limiting oxygen index (LOI) value of air filter paper reached 38.8%, meeting the industry standard for flame retardant materials. Antimicrobial tests confirm that the killing efficiency against E. coli and S. aureus reached 93.9% and 99.99%. Furthermore, OTS containing hydrophobic long chains successfully constructed a multi-layer micro/nanostructure on the paper surface, and its contact angle to water was up to 153.6°. The addition of mercerized fibers also effectively improves the air permeability of the filter paper, which can reach 619 L/m2·s, and subsequent impregnation avoided the impact on the pore size of the material. • A new N-P flame retardant and antimicrobial agent was synthesized and fixed to the paper fibers by chemical grafting. • Excellent flame retardant, antibacterial and hydrophobic properties were achieved. • The high permeability and mechanical properties of filter paper meet the needs of practical use. • The green, low-cost, multi-functional all-fiber air filter material was realized.

Black liquor (BL) bioconversion into valuable by-products is essential to develop a bioeconomy strategy; however, its furfural content hinders microbial fermentation activities. Hence, this study utilizes paper mill sludge (PMS) to provide extracellular enzymes, furfural-degrading microbial consortia, and electron donor required for promoting the BL hydrogenesis potential. Three up-flow anaerobic sequential batch reactors (UASBRs) are fed with PMS (UASBR1), BL (UASBR2), and PMS + BL (UASBR3) and operated in parallel at 15 min fill, 72 h reaction, and 4 h settling. The UASBR3 achieves the maximum volumetric H 2 of 1.483 ± 0.088 L/L/d and H 2 yield of 2.06 ± 0.12 mol/mol glucose, which drops by 88% in UASBR2 and 24% in UASBR1. The insufficient H 2 productivity values in UASBR2 could be due to a lack of nutrients availability (C:N = 440:1 and C:P = 19:1), higher furfural concentration (2116 ± 422 mg/L), and involvement of the butyrate fermentation pathway. The synergetic effect between PMS and BL overcomes these limitations and enriches the fermentation medium with Proteobacteria phyla (22.8%) and Acinetobacter sp. degrading furfural (6.1%). The microbial community at the phylum level (e.g., Proteobacteria , Firmicutes , and Actinobacteria) in UASBR3 maximizes the migration of electrons (e−eq = 9.34 ± 0.54%) towards efficient H 2 formation. [Display omitted] • Paper mill sludge (PMS) mitigated inhibitory effect of furfural in black liquor (BL). • PMS improved H 2 yield from the BL by 8.3-folds and accounted for 2.1 mol/mol glucose. • e– eq transferred to H 2 was 9.3% in the PMS:BL, 7.4% in PMS, and 1.27% in BL. • Acinetobacter degrading furfural (6.1%) was abundant with PMS addition. • Bacilli (8.9%) and Clostridia (5.4%) was dominant in the hydrogenesis of PMS:BL.

• A technology-rich system model is created by integrating operations at MRFs and recycling paper mills. • Our model assesses sustainable pathways for U.S. domestic paper recycling industry. • Domestic recycling rate can increase by 15 % with better collection rate and sorting efficiency. • Use of recycled fibers can reduce energy and carbon intensities for most paper products. Dramatic changes in global recovered paper markets, triggered in large part by Chinese import restrictions, challenge the U.S. to find sustainable pathways for increasing the domestic paper recycling rate. This study presents a technology-rich process model of the U.S. domestic paper recycling industry to assess the energy consumption, carbon emissions, and system costs. A scenario analysis shows the viability of three potential pathways for achieving the national goals of a 15 % increase in both the paper recycling rate and the recycled paper utilization rate. The results suggest that the national goals can be achieved by recovering 80 % of recyclable papers from households and commercial stores, while trading all exported bales to domestic recovery with additional investments in processing capacity expansion. The deployment of advanced technology can enable material recovery facilities (MRFs) and paper mills to produce most recycled paper products that are more energy efficient with fewer CO 2 emissions.

1 Amorphous carbon was facilely obtained via the treatment of waste papers with sulfuric acid. 2 The combination of amorphous carbon with graphitic carbon nitride leads to an increased photo-catalytic H 2 generation. 3 The enhancement in H 2 generation is resultant from the efficient separation of electrons and holes owing to the excellent electrical conductivity of amorphous carbon. Up-cycling of waste papers to value-added carbon products has significant environmental and economic benefits in real life. This work aims to recycle the waste papers to construct amorphous carbon modified graphitic carbon nitride composite photocatalysts for efficient photocatalytic hydrogen generation from water under visible light. Amorphous carbon (labeled as a-C) was yielded from the office waste papers by simple sulphuric-acid treatment and then combined with graphitic carbon nitride (g-CN) to form the g-CN/a-C composite photocatalysts by the thermolysis of a-C and melamine mixture. The addition of a-C enlarges the surface area of g-CN from 11.52 m2 g−1 of pristine g-CN to 28.12 m2 g−1 of g-CN/a-C-100. In addition, the a-C incorporation can significantly separate the electrons from the photoexcited g-CN owing to the excellent conductivity of a-C. As a result, an increased photocatalytic H 2 generation was realized under visible light exposure. The g-CN/a-C-100 sample with optimized a-C contents offers the highest photocatalytic H 2 generation rate of up to 17.1 μ mol h−1, which is ∼12 times higher than that of pristine g-CN under the same condition. The present study manifests the great potential of the recycling of office waste papers for increased photocatalytic H 2 generation. Graphical Abstract [Display omitted]. [ABSTRACT FROM AUTHOR]

Aerogel composites reinforced by fibers have found extensive applications in the field of thermal insulation and energy conservation. However, the composites are hindered by their high infrared radiation transmittance and weak interface adhesion in practical applications. Herein, we designed and prepared a novel thin composite called 'fiber/whisker/aerogel paper' (SWAP) with a thickness of less than 1 mm. The SWAP integrated SiC nanowhiskers (SiC nw) as opacifiers and ultrafine SiO 2 fibers as reinforcement, fabricated through wet manufacturing and sol-gel process. The 'fiber/aerogel paper' (SAP) and SWAP exhibited low thermal conductivity at room temperature, measuring 0.025 W/(m·K) and 0.033 W/(m·K), respectively. Additionally, they exhibited low densities of 0.195 g/cm3 and 0.225 g/cm3, respectively. Notably, SWAP exhibited excellent high-temperature insulation performance, primarily due to its low infrared transmittance (50% at 3 μm). The incorporation of SiC nw and ultrafine SiO 2 fibers collectively enhanced the interfacial adhesion with the aerogel matrix even amidst rigorous testing (weight loss less than 3%). SWAP also demonstrated flexibility, high thermal stability, hydrophobicity, and flame resistance. Furthermore, a comprehensive investigation into the performance variations and influencing g factors of the material was conducted under different heat treatment conditions. This research provides guidance for the application of such materials under high temperatures. [ABSTRACT FROM AUTHOR]

The ZrO 2 fiber paper exhibits excellent thermal insulation properties, however, its limited mechanical strength and insufficient thermal stability hinder its widespread applications. The composite fiber papers, using mullite fibers possessing a high aspect ratio and exceptional thermal stability combined with ZrO 2 fibers, were fabricated via a vacuum-assisted filtration method. This method involved the successive stacking of composite fibers with alumina sol, using vacuum-induced directed water flow to create a layered structure reminiscent of nacre. The layered structure of the nacre, which demonstrates remarkable strength and hardness, has also served as a source of inspiration for the architectural design of the fiber paper. The tensile strength of pure ZrO 2 fiber paper was significantly enhanced by the addition of 7 wt% mullite fibers, resulting in a remarkable increase to 0.1805 kN/m. The paper exhibited exceptional resistance to bending, maintaining 96 % of its bending strength even after undergoing 100 cycles. The thermal shrinkage of the composite paper, containing 15 wt% mullite fibers, was reduced from 17.75 % observed in pure ZrO 2 fiber paper to a mere 1.32 % after undergoing heat treatment at a temperature of 1300 °C for 2 h. The composite paper, measuring 5 mm in thickness and consisting of 7 wt% compositions, displayed exceptional thermal insulation properties when exposed to a hot side temperature of 1370 °C. It effectively insulated temperatures up to approximately 1000 °C. [ABSTRACT FROM AUTHOR]

• A closed-loop material flow analysis model is established for China's pulp and paper industry (CPPI), followed by a comprehensive quantitative analysis from both retrospective and prospective perspectives. • By implementing sound plans and stricter regulations and standards, China has improved recycling and material use efficiency, reduced the organic material with wastewater, and shifted towards recovered paper as a raw material over non-wood fiber. • Lowering the waste paper recycling rate to increase carbon storage is not suitable for China, due to the limited virgin fiber and growing demand. • The growing paper demand requires efforts from both ends of virgin fiber supply and waste paper management towards the sustainable development of CPPI. As the largest global producer and consumer of pulp and paper, China faces significant sustainability challenges in fiber supply and waste paper management. A comprehensive material flow analysis of China's pulp and paper industry (CPPI) is needed to understand the interaction between raw material supply and waste paper management. Here, we construct a closed-loop material flow analysis model for CPPI, examine the evolution patterns of material metabolism from 1990 to 2019, and explore the demand for paper production, waste paper recycling, and virgin fiber supply in 2030 and 2050 under multiple scenarios considering critical factors. Results show that the industry has undergone rapid expansion, increased material use efficiency, and a shift towards recycled pulp from 1990 to 2019. China's paper demand will grow to 186 Mt in the next 30 years, resulting in a significant increase in both demand for fibers (173 Mt) and the generation of waste paper (138 Mt). To ensure a sustainable fiber supply for CPPI, domestic waste paper recycling needs to be prioritized. However, attention should also be paid to the availability of virgin pulp supply and proper disposal of organic solid waste. Proper management of these factors is crucial for achieving a circular economy in the industry and reducing its environmental impact. The findings highlight the importance of addressing both raw material supply and waste paper management for CPPI's sustainable development. [Display omitted] [ABSTRACT FROM AUTHOR]

There are many suggestions offered within the literature to decide if a job type is a profession, some using tick box type trait and characteristics analyses to compare the actions and qualities of individuals to a predefined list. However, there is no specific way to resolve what makes or defines a profession. Writers in many disciplines, including radiography, have used these different models, sometimes with conflicting results. This paper explores the use of Bourdieu's replacement of the concept of profession with that of a 'field', meaning a network of occupants with common attributes, in this case radiographers, in an attempt to resolve this issue. In the UK, radiography practitioners and professional bodies generally use the term profession to describe radiography, and this paper explores a defence of the term for radiography. Using Bourdieu's field theory not only helps define a profession, but also explains the difficulties at the boundaries of professions, and the work needed to protect a profession as a credible entity. This paper supports the argument that radiography is a profession when using Bourdieu's field theory. Radiography continues to work to maintain its status by increasing its symbolic capital by increasing the research output and evidence base of the profession and through role extension. Radiographers can perhaps be assured that radiography is a profession when using Bourdieu's field theory. This paper shows how theoretical frameworks and concepts from outside radiography can be used to support new ways of thinking within the profession. [ABSTRACT FROM AUTHOR]

As a reflection of the scholar's mastery of basic theories and professional knowledge, the dissertation is an important yardstick for measuring the level of scientific research. At present, the problem of academic misconduct is becoming increasingly prominent, which is not only related to personal academic ethics, but also related to the overall development of the national academic and scientific research field. In the traditional method of evaluating the quality of papers, it is mainly based on the evaluation experts' comments and scores. However, there are cases that the evaluation experts' comments and scores are inconsistent in practice. To address this problem, we proposed a paper quality consistency detection model based on the nearest neighbor analysis dimensionality reduction algorithm. Compared with other traditional models, the experimental results show that the detection accuracy of XGBoost model after dimensionality reduction using nearest neighbor analysis algorithm reaches 85.81%.

With prolonged pandemic conditions, and emerging evidence but persisting low awareness of the importance of nutritional derangements, ESPEN has promoted in close collaboration with World Health Organization-Europe a call for papers on all aspects relating COVID-19 and nutrition as well as nutritional care, in the Society Journals Clinical Nutrition and Clinical Nutrition ESPEN. Although more COVID-related papers are being submitted and continue to be evaluated, ESPEN and WHO present the current editorial to summarize the many published findings supporting major interactions between nutritional status and COVID-19. These include 1) high risk of developing the disease and high risk of severe disease in the presence of pre-existing undernutrition (malnutrition) including micronutrient deficiencies; 2) high risk of developing malnutrition during the course of COVID-19, with substantial impact on long-term sequelae and risk of long COVID; 3) persons with obesity are also prone to develop or worsen malnutrition and its negative consequences during the course of COVID-19; 4) malnutrition screening and implementation of nutritional care may improve disease outcomes; 5) social and public health determinants contribute to the interaction between nutritional status and COVID-19, including negative impact of lockdown and social limitations on nutrition quality and nutritional status. We believe the evidence supports the need to consider COVID-19 as (also) a case of malnutrition-enhanced disease and disease-related malnutrition, with added risk for persons both with and without obesity. Similarities with many other disease conditions further support recommendations to implement standard nutritional screening and care in COVID-19 patients, and they underscore the relevance of appropriate nutritional and lifestyle prevention policies to limit infection risk and mitigate the negative health impact of acute pandemic bouts.

Foster care children tend to have greater physical and mental health needs compared to those of their peers who are not in foster care due to many challenges that threaten their well-being. Yet, owing to frequent placement changes, their treatment may be fragmented. Moreover, if foster children are unable to provide important information about their own health status, and the same cannot be obtained from their families of origin, the resulting incomplete and/or inconsistent health history puts them at risk for unrecognized problems and conflicting diagnoses. Paradoxically, foster parents and resource providers often request psychotropic medications for children and youth in their care as a means of managing their behaviors. The phenomenon of inappropriate polypharmacy arises due in part to the difficulties related to integrating trauma-informed principles into the care process. It is further exacerbated by the complexity of intersecting systems in which child welfare case workers need to communicate including foster and biological parents, social service agencies, and advocates. In this second paper, we report on the same intervention as that discussed in the first paper, focusing on the effectiveness of the live 2-hour face-to-face training for child welfare staff and the 3-month web-based curriculum for leadership personnel in improving the participants' trauma responsiveness. 1. What are the child welfare staff's perceptions of their own knowledge, attitudes, and communication behaviors associated with medications used to treat mental health symptoms and monitoring for side-effects of psychotropic medication use in children? 2. What is the level of trauma responsiveness among child welfare staff? The ABC Medication Scale was employed to measure staff knowledge, attitudes, and behaviors associated with medications used to treat mental health symptoms before and after the intervention to determine if the training resulted in any improvements. Individual- and organizational-level trauma responsiveness was rated on a continuum of the Missouri Model: A Developmental Framework for Trauma-Informed Approaches. Artifacts of the web-based curriculum and qualitative interview data were analyzed by applying grounded theory methods. There was a significant increase in The ABC Medication Scale scores following the training. The qualitative findings further revealed that majority of the participants rated themselves as "trauma aware" or "trauma responsive" on the Missouri Model, while indicating that their agencies could work harder to become more fully trauma-informed. As trauma-informed child welfare workforce that understands the complexity and advocacy requirements of psychotropic medication management is needed, further longitudinal research is required is to assess the training effects over time. In particular, the aim should be to establish (a) how knowledge and attitude shifts correlate with greater degrees of trauma responsiveness, and (b) if and how such trainings translate into improved systems of support.

The phenomenon of inappropriate polypharmacy among the foster care population arises in part due to the challenges related to integrating trauma-informed principles into service delivery. It is further exacerbated by the complexity of intersecting systems in which child welfare case workers need to communicate, including foster and biological parents, social service agencies, and advocates. Yet, there is limited research about trauma-informed psychotropic medication management interventions for child welfare staff. This pilot study was conducted to evaluate a trauma-informed psychotropic medication management intervention and is reported in two manuscripts, pertaining respectively to the facilitators and barriers to learning, and perceived individual and institutional trauma responsiveness. The intervention comprised of a 2-hour-long training session for child welfare staff and a 3-month web-based curriculum for leadership personnel, aiming to increase their understanding of trauma-informed psychotropic medication management. In the first paper, we report on the facilitators and barriers to learning, grouped into three categories: teacher attributes, learner attributes, and situational factors. In the second paper, in addition to trauma responsiveness ratings, we also provide a detailed account of one participant's life experience and perceptions of the intervention provided, as an exemplar of the psychosocial facets of resilience. The ABC Medication Scale scores that measured staff knowledge, attitudes, and behaviors associated with medications used to treat mental health symptoms showed a significant change in scores following training. Based on these findings, we provide practical solutions to address situational factors that are worth considering when providing training for child welfare staff. Given that foster care children experience many challenges that threaten their well-being, their physical and mental health needs tend to be greater than those of their peers who are not in foster care. However, owing to the transient nature of the foster care placements, as well as continuous changes in medical providers and counselors, the screenings, supportive interventions, and treatments they receive may be fragmented. This is particularly problematic when considering that many of these children are medicated as a means of managing their behavior. Moreover, children in foster care are also more vulnerable to having the medications and diagnoses accumulate due to frequent placement changes and lack of treatment continuity. Our research was guided by the question "What are the facilitators and barriers to learning about trauma-informed psychotropic medication management?" We developed an intervention to address the issue of inappropriate polypharmacy and examined the facilitators and barriers to learning using a mixed methods design. The facilitators to learning were instructor-specific (e.g., reputation, teaching style, capacity for selecting and implementing relevant resources), learner-specific (altruism, capacity to see personal relevance in the learning situation, desire for knowledge/competence, career advancement/recognition-seeking), and situational (immediacy/on-demand resources, reinforcement of pleasant learning experience). Barriers were largely situational (workload and family demands). Based on these findings, we provide practical strategies for addressing situational factors that are worth considering when designing training curricula aimed at child welfare staff.

Rewritable paper is of great significance for environmental and sustainable development. Specially, the water rewritable paper based on hydrochromism has aroused extensive research interesting for being clean, convenient and compatible with the current ink jet printer. Nevertheless, previously reported water rewritable paper requires complex and time-consuming fabricating process. Here, we report a facile strategy to fabricate structural colored water rewritable paper simply via two step infiltration on commercially available paper. After infiltration of graphene laminates and SiO 2 colloidal spheres in sequence, the obtained paper is integrated with assembled graphene laminates (AGLs)/amorphous colloidal arrays (ACAs) hierarchical composite structure. Owing to the advantageous micro-topography, selective separation capacity and high visible light absorption property of the underlying AGLs, SiO 2 ACAs with vivid structure color can be realized. Moreover, the hydrochomism of the hierarchical composite structure is resulted from the synergistic contribution of the hydrophilic structural color and the visible light absorption property of AGLs. Our strategy is based on the environmental-friendly structural color and convenient to realized, which offers a promising alternative to rapidly fabricate colored water rewritable paper.
