AbstractSome previous studies suggested that the plasma exchange (PE) and hemoperfusion (HP) played a cardinal role in the treatment of severe coronavirus disease 2019 (COVID‐19) cases by diminishing the cytokine storm. This study aimed to assess the effects of PE and HP on cytokine storms in patients with severe COVID‐19 through a systematic scoping review. Four Electronic databases (Medline [accessed from PubMed], Scopus, Science Direct, and Cochrane library) were searched systematically on February 2, 2021, using MESH terms and related keywords in the English language. Considering the titles and abstracts, unrelated studies were excluded. The full texts of the remained studies were evaluated by authors, independently. Then, their findings were assessed and reported. A total of 755 articles were obtained within the first step of searching, and 518 remained after removing the duplications. Through the title and abstract screening, 438 were removed. Of the rest, 59 papers were excluded. Finally, after reading the full text of the remained articles, 21 were included in data extraction. Most of the previously reported evidence were case reports and case series. Findings were summarized in two categories. The first category encompassed nine studies regarding HP and continuous renal replacement therapy, and the second category included twelve studies about PE. The results revealed that HP and PE within the cytokine storm phase would be beneficial with a high probability in the treatment of severely ill COVID‐19 patients.Highlights Some studies showed that plasma exchange (PE) and hemoperfusion (HP) played an important role in the treatment of patients with severe COVID‐19 disease.

AbstractA compact pattern diversity patch antenna working at 5.8 GHz is proposed. The patch antenna has two ports, which are responsible for the broadside radiation and omni‐directional radiation, respectively. The broadside radiation is achieved by inserting a substrate slot‐loaded integrated waveguide (SIW) cavity at the center of the patch antenna, and the omni‐directional pattern is realized by exciting the shorted patch in‐phase from both sides of the SIW cavity. Although the two operating modes share the same radiator, but a high isolation of over 30 dB is achieved, due to the cancellation of current at the inputs. In addition, two approaches are investigated to enhance the operation bandwidths. The pattern diversity antenna is prototyped and measured, showing an impedance bandwidth of 5.69–5.92 GHz for both modes/channels, and a high inter‐channel isolation over 30 dB, making it suitable for indoor wireless communication systems.

AbstractBackgroundMusculoskeletal (MSK) health is central to health, well‐being, physical functioning and healthy ageing. It is a public health priority to help maintain and improve the MSK health of the population across the life‐course. An important environment for supporting MSK health is the workplace.MethodA workplace Joint Pain Advice (JPA) service was piloted in 20 organisations of various sizes in Cornwall and London with 481 people accessing the service. A qualitative evaluation of the project was carried out in Cornwall with 24 JPA participants from 11 organisations taking part in interviews and focus groups.ResultsParticipants valued the service, the impact it had had on their physical and mental health and well‐being and its effects on the management of their MSK health in the workplace. The service served the unmet need for support to self‐manage MSK pain and participants found its delivery in the workplace convenient and efficient. Participants reported changing the ways in which they performed their role in the workplace and taking actions to protect their MSK health and relieve their pain. JPA participants felt more willing and better able to talk about their MSK problems with their colleagues and managers and felt more ‘empowered’ to ask their manager about how to accommodate their MSK problems in the workplace.ConclusionJPA in the workplace presents a model for delivering MSK services to businesses of all sizes which warrants further evaluation to measure its effect on absenteeism and presenteeism in small, medium‐sized and larger organisations.

AbstractThe COVID‐19 pandemic has had devastating effects on Black and rural populations with a mortality rate among Blacks three times that of Whites and both rural and Black populations experiencing limited access to COVID‐19 resources. The primary purpose of this study was to explore the health, financial, and psychological impact of COVID‐19 among rural White Appalachian and Black nonrural central Kentucky church congregants. Secondarily we sought to examine the association between sociodemographics and behaviors, attitudes, and beliefs regarding COVID‐19 and intent to vaccinate. We used a cross sectional survey design developed with the constructs of the Health Belief and Theory of Planned Behavior models. The majority of the 942 respondents were ≥36 years. A total of 54% were from central Kentucky, while 47.5% were from Appalachia. Among all participants, the pandemic worsened anxiety and depression and delayed access to medical care. There were no associations between sociodemographics and practicing COVID‐19 prevention behaviors. Appalachian region was associated with financial burden and delay in medical care (p = 0.03). Appalachian respondents had lower perceived benefit and attitude for COVID‐19 prevention behaviors (p = 0.004 and <0.001, respectively). Among all respondents, the perceived risk of contracting COVID was high (54%), yet 33.2% indicated unlikeliness to receive the COVID‐19 vaccine if offered. The COVID‐19 pandemic had a differential impact on White rural and Black nonrural populations. Nurses and public health officials should assess knowledge and explore patient's attitudes regarding COVID‐19 prevention behaviors, as well as advocate for public health resources to reduce the differential impact of COVID‐19 on these at‐risk populations.

AbstractObjectiveBasal ganglia regions are part of the brain’s reward‐processing networks and are implicated in the neurobiology of obesity and eating disorders. This study examines basal ganglia microstructural properties in adults with and without obesity.MethodsDiffusion basis spectrum imaging (DBSI) images were analyzed to obtain putative imaging markers of neuroinflammation. Relationships between basal ganglia DBSI metrics and reward sensitivity and eating behaviors were also explored.ResultsA total of 46 participants (25 people with obesity; aged 20‐40 years; 37 women) were included. Relative to the people in the normal‐weight group, people with obesity had smaller caudate and larger nucleus accumbens (NAcc) volumes (p < 0.05) and lower DBSI fiber fraction (reflecting apparent axonal/dendrite density) in NAcc and putamen, higher DBSI nonrestricted fraction (reflecting tissue edema) in NAcc and caudate, and higher DBSI restricted fraction (reflecting tissue cellularity) in putamen (p ≤ 0.01, all). Increased emotional and reward eating behaviors were related to lower NAcc axonal/dendrite density and greater tissue edema (p ≤ 0.002). The relationships between emotional eating and adiposity measures were mediated by NAcc microstructure.ConclusionsThese findings provide evidence that microstructural alterations in basal ganglia relate to obesity and insights linking NAcc microstructure and eating behavior in adults.
Green epoxy resin/date stone flour biocomposites: Effect of filler chemical treatments on elastic properties

Published: July 2021

AbstractThis work aims to study the effect of chemical treatments of date stone flour (DSF) as a filler on the elastic properties of biocomposites based on green epoxy resin (GER) used as a matrix. The main disadvantages of natural reinforcements in biocomposites are the poor compatibility between the reinforcement and the matrix as well as the relatively high moisture sorption. Different chemical treatments using soda (alkaline), benzoyl chloride, and potassium permanganate were applied to the DSF filler. Then, the filler was incorporated into the matrix at 30 wt% to obtain GER/DSF biocomposites. The elastic properties of the biocomposites, namely, longitudinal modulus, shear modulus, bulk modulus, Young's modulus of elasticity, acoustic impedance, Poisson's ratio, and ultrasonic microhardness, were determined using ultrasonic through‐transmission method. In addition, the morphology was studied using microscopy analysis. The results obtained revealed a decrease of the elastic properties of the pretreated‐filler biocomposite compared to the pure GER. On the other hand, the chemical treatment of the filler leads to an improvement of the elastic properties of GER/DSF biocomposites. The permanganate treatment is the most suitable for GER/DSF biocomposites. The morphology analysis through optical microscopy and scanning electron microscopy showed that chemical treatments enhance the interfacial adhesion between the DSF filler and the GER matrix.

AbstractThe afterburning effect of aluminized explosives makes them have strong damage ability to soft targets, but the aluminum particles in the composition often cannot achieve proper combustion. The high ignition temperature of micron aluminum powder is one of the main reasons. In this work, we introduce nanothermite reaction with low onset temperature (<660 °C) into aluminized explosives by replacing the base explosives with energetic coordination polymers (ECPs). The decomposition products of many ECPs contain corresponding metal oxides that will react with aluminum via thermite reaction. Three kinds of ECPs ([CoC2H4N8O4]n, [NiC2H4N8O4]n and [CuC2H4N8O4]n) are constructed and compounded with nano‐aluminum (nano‐Al) particles to form aluminized ECPs. The influence of metal ion species and Al/Metal (Al/Me) molar ratio on their energetic properties are systematically studied. The results show that the exothermic thermite reaction with low onset temperature plays an important role in the combustion propagation of aluminized ECPs, and the possible mechanism is proposed. When the Al/Me molar ratio is 3–4, the aluminized ECPs have the best peak pressure and pressurization rate. At the optimum molar ratio, the pressure and pressurization rate of aluminized ECP(Co) are much higher than those of aluminized ECP(Ni) and ECP(Cu). Among the three kinds of aluminized ECPs, the aluminized ECP(Co) has the best energetic characteristics and can be used as a preferred choice. However, for the applications that require a long‐time heat supply, aluminized ECP(Cu) will be suitable.
Observer‐based adaptive event‐triggered PID control for networked systems under aperiodic DoS attacks
Authors: Wu Jiancun , Peng Chen 
Published: July 2021

AbstractIn the present article, the observer‐based proportional integral derivative (PID) security control problem is investigated for a networked system subject to aperiodic denial‐of‐service (DoS) attacks. First, by carefully modeling cyberattacks as aperiodic DoS attacks, a suitable switching observer is constructed to solve the state reconstruction problem. Second, to improve the utilization of network resources while resisting the impact of attacks, an adaptive event‐triggered communication protocol is introduced, whose trigger parameters can be dynamically adjusted according to the set learning rules. Third, based on the above analysis, an error switching system model is established, which describes the impact of the adaptive triggered protocol and aperiodic attacks in a unified framework. Then, by employing the switched system analysis method, sufficient conditions are obtained to ensure the error switched system being asymptotically stable. Furthermore, by means of orthogonal decomposition technique, a codesign method of the observer gains, triggered parameter, and PID controller gains is given. Finally, a simulation example is provided to illustrate the efficiency and applicability of the obtained results.

AbstractAlthough aqueous Zn‐ion batteries (ZIBs) with low cost and high safety show great potential in large‐scale energy storage system, metallic Zn anode still suffers from unsatisfactory cycle stability due to unregulated growth of Zn dendrites, corrosion, and formation of various side products during electrochemical reaction. Here, an ultrafast and simple method to achieve a stable Zn anode is developed. By simply immersing a Zn plate into an aqueous solution of CuSO4 for only 10–60 s, a uniform and robust protective layer (Zn4SO4(OH)6·5H2O/Cu2O) is formed on commercial Zn plate (Zn/ZCO), which enables uniform electric field distribution and controllable dendrite growth, leading to a long‐term cycle life of over 1400 h and high average Coulombic efficiency (CE) of 99.2% at 2.0 mA cm−2 and 2.0 mAh cm−2. These excellent characteristics of the prepared Zn anode show great potential in practical applications for high‐performance aqueous Zn‐ion batteries.

Published: July 2021

AbstractEmerging digital assessment of biomarkers by linking health‐related data obtained from wearable electronic devices and embedded health and fitness sensors in smartphones is opening up the possibility of creating a continuous remote‐monitoring platform for disease management. It is considered that the built‐in flashlight of smartphones may be utilized to remotely program genetically engineered designer cells for on‐demand delivery of protein‐based therapeutics. Here, the authors present smartphone‐induced insulin release in β‐cell line (iβ‐cell) technology for traceless light‐triggered rapid insulin secretion, employing the light‐activatable receptor melanopsin to induce calcium influx and membrane depolarization upon illumination. This iβ‐cell‐based system enables repeated, reversible secretion of insulin within 15 min in response to light stimulation, with a high induction fold both in vitro and in vivo. It is shown that programmable percutaneous remote control of implanted microencapsulated iβ‐cells with a smartphone's flashlight rapidly reverses hyperglycemia in a mouse model of type‐1 diabetes.

Published: July 2021

AbstractThe authors present a plan for classroom teachers and literacy professionals to conduct case studies, particularly of students’ reading motivations and engagement. The authors argue for case study as a way for practitioners to contribute important knowledge to the field that is grounded in practitioners’ deep, contextual understanding of the realities of classroom life. A roadmap for conducting a case study is presented, beginning with the selection of an inquiry topic and proceeding through data collection, analysis, and sharing of results. The roadmap is grounded in examples from the authors’ and other practitioner researchers’ case studies of reading motivation and engagement, and additional resources and suggestions for accomplishing a case study within the constraints of classroom routines are provided.

AbstractBackground and AimsBarrett's esophagus (BE) is accompanied by an increased risk of developing esophageal cancer. Accurate risk‐stratification is warranted to improve endoscopic surveillance. Most data available on risk factors is derived from tertiary care centers or from cohorts with limited surveillance time or surveillance quality. The aim of this study was to assess endoscopic and clinical risk factors for progression to high‐grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in a large prospective cohort of BE patients from community hospitals supported by an overarching infrastructure to ensure optimal surveillance quality.MethodsA well‐defined prospective multicenter cohort study was initiated in six community hospitals in the Amsterdam region in 2003. BE patients were identified by PALGA search and included in a prospective surveillance program with a single endoscopist performing all endoscopies at each hospital. Planning and data collection was performed by experienced research nurses who attended all endoscopies. Endpoint was progression to HGD/EAC.ResultsNine hundred eighty‐five patients were included for analysis. During median follow‐up of 7.9 years (IQR 4.1–12.5) 67 patients were diagnosed with HGD (n = 28) or EAC (n = 39), progression rate 0.78% per patient‐year. As a clinical risk factor age at time of endoscopy was associated with neoplastic progression (HR 1.05; 95% CI 1.03–1.08). Maximum Barrett length and low‐grade dysplasia (LGD) at baseline were endoscopic predictors of progression (HR 1.15; 95% CI 1.09–1.21 and HR 2.36; 95% CI 1.29–4.33).ConclusionRisk of progression to HGD/EAC in a large, prospective, community‐based Barrett's cohort was low. Barrett's length, LGD and age were important risk factors for progression.(www.trialregister.nl NTR1789)

Published: July 2021

AbstractThe use of acid‐modified mango pod (AMMP) sorbent for removing Rhodamine B (Rh‐B) dye from aqueous media was investigated. Raw mango pod (RMP) and AMMP sorbents were characterized using scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), powdered X‐ray diffractogram (PXRD), Fourier transform infrared (FTIR), point of zero charge pH (pHpzc), and Boehm titration (BT) techniques. Batch adsorption was employed to examine the influence of operational factors. Sorption kinetic parameters were calculated using pseudo‐first‐order, pseudo‐second‐order, Elovich, and intraparticle diffusion models. The pseudo‐second‐order model best fitted the adsorption kinetic data most with maximum correlation coefficient (R2 > 0.99). The process of the adsorption was controlled by both boundary layer and intraparticle diffusion mechanisms. Four isotherm models (Langmuir, Freundlich, Dubinin–Radushkevich, and Temkin) were utilized to analyze the equilibrium data at various temperatures. Freundlich model gave the best fit with the maximum regression (0.99), while the Langmuir isotherm model established a maximum monolayer adsorption capacity of 500 mg g−1. Thermodynamic parameters studied revealed that the interaction is spontaneous and endothermic in nature. The cost analysis of the current study provides convincing proof that AMMP is efficient for removing Rh‐B dye from solution by providing a saving of 225.2 USD/kg, which is eight times cheaper than commercial activated carbon. Consequently, the study revealed that AMMP is a viable, effective, and sustainable sorbent for Rhodamine B dye removal.Practitioner points

The powdered X‐ray diffractogram (PXRD) showed the formation of new and intense peaks with the presence of highly organized crystalline structures on acid‐modified mango pod (AMMP).
Surface morphology of AMMP showed well‐developed open surface pores required for effective adsorption of Rh B dye molecules.
Economic feasibility of the present study showed that AMMP is more affordable than commercial activated carbon that costs USD 259.5/kg, thus translated to a saving cost of USD 225.2/kg and more than 7.5 times cheaper than the commercial activated carbon (CAC).

Abstract
Purpose
To evaluate the efficacy and safety of lung low-dose radiation therapy (LD-RT) for pneumonia in patients with coronavirus disease 2019 (COVID-19).

Materials and methods
Inclusion criteria comprised patients with COVID-19-related moderate–severe pneumonia warranting hospitalization with supplemental O2 and not candidates for admission to the intensive care unit because of comorbidities or general status. All patients received single lung dose of 0.5 Gy. Respiratory and systemic inflammatory parameters were evaluated before irradiation, at 24 h and 1 week after LD-RT. Primary endpoint was increased in the ratio of arterial oxygen partial pressure (PaO2) or the pulse oximetry saturation (SpO2) to fractional inspired oxygen (FiO2) ratio of at least 20% at 24 h with respect to the preirradiation value.

Results
Between June and November 2020, 36 patients with COVID-19 pneumonia and a mean age of 84 years were enrolled. Seventeen were women and 19 were men and all of them had comorbidities. All patients had bilateral pulmonary infiltrates on chest X‑ray. All patients received dexamethasone treatment. Mean SpO2 pretreatment value was 94.28% and the SpO2/FiO2 ratio varied from 255 mm Hg to 283 mm Hg at 24 h and to 381 mm Hg at 1 week, respectively. In those who survived (23/36, 64%), a significant improvement was observed in the percentage of lung involvement in the CT scan at 1 week after LD-RT. No adverse effects related to radiation treatment have been reported.

Conclusions
LD-RT appears to be a feasible and safe option in a population with COVID-19 bilateral interstitial pneumonia in the presence of significant comorbidities.
