Published: July 2020

The aim of this study was to determine the prevalence of hepatitis C virus amongst patients attending five selected hospitals in Niger State. A total of 565 blood samples were screened using enzyme linked immunosorbent assay (ELISA) test kit for anti- hepatitis C virus (HCV). Structured questionnaires were administered to participants and data were analyzed using SPSS Version 19.0 with P < 0.05 as the level of significance. HCV infection was detected in 44 out of the 565 blood samples examined. The overall prevalence was 7.8% with male 4.8% and female 3.0% respectively. Participants within age group 31-40 years had the highest prevalence (11.5%), 41-50 years followed closely with 11.0%, while >1-10 years, 21-30 years, ≥60 years and above, 51-60 years and 11-20 years had 9.1%, 8.3%, 4.0%, 3.5% and 2.3% in that order. All the demographic variables and risk factors considered in this study were not significantly associated with anti- HCV seropositives. The prevalence of HCV infection in Niger State was not high when compared with similar studies. However, compulsory public awareness campaigns against HCV infection and prevention programmes should be intensified.

Published: July 2020

Ignaz Semmelweis the father of hand hygiene made this startling discovery of strong association of contaminated hands with incidence of puerperal fever and deaths in 1847 and embarked on aggressive campaign to stem the tide of maternal deaths at that time and eventually succumbed to death due to septicaemia in 1865. At present about 171 years since this discovery, the entire humanity is yet to fully embrace the full practice of hand hygiene and reduce as much as half of the morbidities and mortalities from communicable diseases across the globe. Sub-Saharan Africa remains the last stronghold of millions of avoidable deaths from poor hand hygiene and 156 million people from Nigeria are yet to have access to facilities for hand hygiene. Facilities for hand hygiene should be adequately provided in all hospitals and clinics, schools and all settings experiencing assemblage of crowds while health education and advocacy is stepped. This will serve as a mark of honour to Ignaz Semmelweis, the man that paid the supreme price saving the lives of millions across the globe in defence of hand hygiene.

A Leishmaniose Tegumentar Americana (LTA) é uma doença zoonótica negligenciada, que afeta a pele e as mucosas, causada por diferentes espécies do gênero Leishmania. O objetivo deste estudo foi analisar o perfil demográfico, clínico, geográfico e temporal dos casos de LTA registrados no período 2000-2019, na secretaria de saúde do município de Cáceres/MT. A informação demográfica dos casos registrados foi analisada por: Perfil demográfico, Aspectos clínicos, Distribuição geográfica e temporal e Taxa de incidência anual. A maior prevalência encontrada foi em homens na faixa etária de 20 a 60 anos. Aproximadamente 81% dos casos eram de leishmaniose cutânea. As profissões mais afetadas foram os lavradores e trabalhadores braçais. A proporção entre os casos rurais e urbanos foi similar. Ao analisar o perfil demográfico apenas dos casos urbanos, os aposentados, donas do lar e estudantes foram o grupo mais afetado. A LTA foi amplamente distribuída, em diversos bairros do centro urbano da cidade. Concluímos que a LTA em Cáceres/MT afeta principalmente a população produtiva masculina. Contudo, nos casos urbanos a população mais afetada esta formada por aposentados, donas do lar e estudantes sugerindo a possibilidade de eventuais surtos endêmicos.
Uma solução viável para a reciclagem de resíduos industriais de ardósia em pavimentação

Published: July 2020

O presente artigo discorre sobre pesquisa acerca do uso de material alternativo, ambientalmente inerte, caso dos rejeitos industriais britados de ardósia, fisicamente transformados em agregados, como integrantes das camadas granulares e de revestimento de um pavimento asfáltico. Trata-se uma solução viável, do ponto de vista técnico e ambiental, para a reciclagem deste tipo de material em pavimentos asfálticos, contribuindo para a mitigação de impactos ambientais decorrentes da exploração da ardósia - rocha ornamental - na maior província do mundo de ocorrência deste tipo de litológico. O estudo está centrado na construção de uma pista em um trecho experimental, no município de Papagaios, MG, para acompanhamento de seu desempenho ao longo do tempo. Os agregados de ardósia foram preliminarmente submetidos aos ensaios de caracterização física e química. Como integrantes de um sistema de camadas, esses agregados, em mistura solo-brita graduada simples, e em mistura com cimento asfáltico de petróleo (CAP 50/70), foram também submetidos aos ensaios de caracterização mecânica e de cargas cíclicas, no contexto da mecânica dos pavimentos. Os resultados encontrados permitiram constatar que o material por si mesmo é resistente à meteorização, e do ponto de vista geotécnico, resistente ao desgaste por abrasão e ao ataque químico, possui baixa absorção, baixa degradação com e sem ligante, baixa presença de finos plásticos e satisfatória adesividade a ligante asfáltico. Os parâmetros volumétricos da metodologia Marshall, como também estabilidade e resistência à tração, integralmente atendidos, não o invalidam para uso rodoviário, inclusive no capeamento asfáltico, em misturas a quente. Aplicado o novo método de dimensionamento nacional – MeDiNa, este prognosticou um bom desempenho da pista do trecho experimental para seu período de projeto. A utilização de ardósia, como material de pavimentação, empregado na Região Central de Minas Gerais, onde é abundante, evitará exploração de novas jazidas de agregados convencionais, e concorrerá para emprego e renda na região, com maior sustentabilidade ambiental.

Let K be a convex polyhedron and ℱ its Wulff energy, and let denote the set of convex polyhedra close to K whose faces are parallel to those of K. We show that, for sufficiently small ε, all ε‐minimizers belong to As a consequence of this result we obtain the following sharp stability inequality for crystalline norms: There exist γ = γ(K, n) > 0 and σ = σ(K, n) > 0 such that, whenever ∣E ∣  =  ∣ K∣ and ∣EΔK ∣  ≤ σ, thenurn:x-wiley:00103640:media:cpa21928:cpa21928-math-0003
In other words, the Wulff energy ℱ grows very fast (with power 1) away from The set appearing in the formula above can be informally thought as a sort of “projection” of E onto Another corollary of our result is a very strong rigidity result for crystals: For crystalline surface tensions, minimizers of ℱ(E) + ∫Eg with small mass are polyhedra with sides parallel to the those of K. In other words, for small mass, the potential energy cannot destroy the crystalline structure of minimizers.

High‐rate uncoded space‐time labelling diversity with low‐complexity detection
Authors: Patel Sulaiman Saleem , Quazi Tahmid , Xu Hongjun 
Published: July 2020

SummaryUncoded space‐time labelling diversity (USTLD) is a recent scheme that improved the error performance compared to conventional multiple‐input, multiple‐output systems. Thus far, USTLD has suffered from limited achievable data rates, as the original model uses only two transmit antennas. This motivates for the work in this paper, where the USTLD model is extended to allow for any desired number of transmit antennas. An analytical bound for the average bit error probability of this high‐rate USTLD (HR‐USTLD) system is derived. This expression is verified using the results of Monte Carlo simulations, which show a tight fit in the high signal‐to‐noise ratio region. The increased data rates associated with larger transmit antenna arrays in HR‐USTLD systems come at the cost of increased detection complexity. Therefore, this paper studies the application of low‐complexity detection algorithms based on the popular QR decomposition technique and proposes a new algorithm specifically designed for HR‐USTLD systems. Analysis of this algorithm in terms of accuracy and computational complexity is also provided and benchmarked against maximum‐likelihood detection (MLD). It is shown that the proposed algorithm achieves near‐MLD accuracy, while reducing complexity by 79.75% and 92.53% for the respective 4 × 4 16QAM and 4 × 5 16PSK HR‐USTLD systems investigated.
A transparent robust quasi‐isotropic circularly polarized antenna for Cub‐Sat and outdoor wireless
Authors: Dashti Ardakani Mansoor , Tabatabaefar Marzie 
Published: July 2020

AbstractIn this article, a highly robust antenna is proposed for omnidirectional circular polarized communications in harsh environments at 2.45 GHz industrial, scientific, and medical frequency band. Circular polarization is realized by utilizing a combination of two magnetic and electric dipoles. The proposed antenna is based on a transparent structure and covered by a quarter wavelength thick layer of plexiglass to achieve desired robustness and visible light transparency. Meanwhile, because of the high transparency of the glass, it can integrate with solar cells to simultaneously propagate signals and harvest energy. The average gain and bandwidth of the antenna are 1.7 dBic and 300 MHz, respectively. The antenna's axial ratio is achieved less than 3 dB within the bandwidth, showing circular polarization behavior. The proposed compact antenna is numerically and experimentally analyzed and the results have a great agreement. In another viewpoint, the structure delivers promising possibilities to improve the propagating and radiating properties, which bring in significant advantages for real‐world multifunctional applications.

AbstractExcessive exposure to N,N‐dimethylformamide (DMF) can lead to occupational liver poisoning in workers; however, the underlying mechanism is not fully clarified. The importance of microRNAs (miRNAs) in chemical‐induced hepatotoxicity has been demonstrated. To determine whether miRNAs are also involved in DMF‐induced hepatotoxicity, we systematically analyzed the miRNA expression profiles in DMF‐treated (75 and 150 mm) HL‐7702 liver cells and controls by high‐throughput sequencing. Among the altered miRNAs, miR‐192‐5p was the most significantly upregulated in HL‐7702 cells after DMF exposure and was involved in DMF‐mediated cell apoptosis. By contrast, suppression of miR‐192‐5p in HL‐7702 cells attenuated the apoptosis induced by DMF. Furthermore, the anti‐apoptotic gene (NIN1/RPN12 binding protein 1 homolog [NOB1]) was predicted to be a potential miR‐192‐5p target according to bioinformatics analysis. The direct interaction between miR‐192‐5p and NOB1 was confirmed by the dual‐luciferase activity assay in HEK293FT cells. Overexpression of miR‐192‐5p efficiently reduced NOB1 mRNA and protein expression in HL‐7702 cells. Alteration in NOB1 expression influenced DMF‐induced hepatotoxicity by affecting hepatic apoptosis. In addition, the inverse correlation between miR‐192‐5p expression levels and NOB1 expression was further confirmed in DMF‐exposed mouse liver tissue samples. These observations demonstrated that promotion of apoptosis from the suppression of NOB1 by miR‐192‐5p overexpression was responsible for the DMF‐induced hepatotoxicity. This work provides the molecular mechanism at the miRNA level for hepatic apoptosis induced by DMF.
Anaplastic large cell lymphoma as a posttransplant lymphoproliferative disorder in a renal transplant patient: A case report
Authors: Alabdulbaqi Manar , Toupin Melissa , Berardi Philip , McCurdy Arleigh 
Published: July 2020

AbstractWe report a case of a 45‐year‐old female who developed an ALK‐positive anaplastic large cell lymphoma (ALCL) 9 years after renal transplant. The patient underwent a cadaveric renal transplant for diabetic nephropathy, and presented 9 years later with fever and multiorgan dysfunction. The initial CT scans showed multiple enlarged supra‐ and infradiaphrgamatic lymph nodes. A CT‐guided core needle biopsy of a retroperitoneal lymph node revealed ALK positive ALCL. She received six cycles of cyclophosphamide, adriamycin, vincristine, etoposide, and prednisone, and has been in remission for over 3 years. Monomorphic T‐cell posttransplant lymphoproliferative disorder (PTLD) is an established but rare entity of PTLD and generally carries poor prognosis. This is a case report of a late PTLD with pathology reporting an aggressive T‐cell lymphoma that has been successfully treated with multiagent chemotherapy.

AbstractBackgroundAssess the acceptability and feasibility of delivering Reboot, a telephone dietary intervention to parents of pediatric cancer survivors. The research question asks whether tailored dietary support is acceptable and feasible to deliver to parents of young cancer survivors who have recently completed cancer treatment?ProcedurePre‐post study. Nineteen parents of pediatric cancer survivors (aged 2‐13 years) in remission, who had received cancer treatment at a tertiary children's hospital, less than 5 years prior to the intervention. Participants received four weekly 45‐min telephone sessions led by a psychologist or dietitian and one postintervention booster session 6 weeks later. Sessions addressed strategies to increase children's vegetable and fruit intake.ResultsOf the 19 parents who started the intervention, 14 completed all sessions within 8 weeks and 12 completed the booster session within 10 weeks. The mean session duration was 47 min. All participants reported that Reboot increased their confidence and knowledge about promoting healthy eating habits to their child.ConclusionsReboot is an acceptable intervention in young cancer survivors aimed at increasing vegetable and fruit intake after cancer treatment. Implications for cancer survivors: The results from the Reboot pilot provides preliminary evidence that a targeted intervention to improve the diets of childhood cancer survivors may be feasible with future modification.
Progressive resistance exercise for improving pain and disability in chronic neck pain: A case series

Published: July 2020

AbstractObjectivesChronic neck pain is known to be associated with neck muscle weakness. However, many strengthening programs do not target multi‐directional weakness in a functional position. Specialised assessment and treatment technology that is able to strengthen the neck muscles in an upright position may be used to achieve this. There is little research available on the efficacy of neck‐specific progressive resistance exercise interventions in patients with chronic neck pain; therefore, this study aimed to determine whether this style of program led to a change in pain and disability, and to investigate the relationship between neck strength, pain and disability.MethodsSecondary analysis of participants with chronic neck pain who completed a minimum of nine sessions of a neck‐specific progressive resistance program at a physiotherapy clinic between the years of 2002 and 2018. Outcomes were the Neck Disability Index (NDI), Numerical Rating Scale of Pain (NRS) and multi‐directional neck strength (flexion, extension and lateral flexion – pounds). Data were analysed through paired samples t‐tests and backwards stepwise multiple linear regression models.ResultsA total of 127 participants were eligible for inclusion. All neck strength measures, NDI scores and NRS scores showed significant improvements after the nine sessions (all p < .0001). Significant predictors of NDI were symptom duration (β = −0.023, p = .009) and NRS score (β = 4.879, p < .000). Significant predictors of NRS were symptom duration (β = 0.004, p = .005), NDI score (β = 0.105, p < .000), extension strength (β = −0.950, p = .012) and gender (β = 0.777 [male =1, female = 0], p = .029).ConclusionThis study showed that a neck‐specific progressive resistance exercise intervention led to significant improvement in neck strength, pain and disability in a clinical population. However, caution should be taken when interpreting results due to a lack of comparison group and the variation in treatment given and, therefore, further higher‐quality research should be undertaken to confirm these findings.

deformation of two dimensional Yang-Mills theory on general curved backgrounds. We compute the deformed partition function through an integral transformation over frame fields weighted by a Gaussian kernel. We show that this partition function satisfies a flow equation which has been derived previously in the literature, which now holds on general backgrounds. We connect ambiguities associated to first derivative terms in the flow equation to the normalization of the functional integral over frame fields. We then compute the entanglement entropy for a general state in the theory. The connection to the string theoretic description of the theory is also investigated.
Tender evaluation through efficiency analysis for public construction contracts
Authors: Niewerth Stefan , Vogt Peter , Thewes Markus 
Published: July 2020

AbstractGiven the European Public Procurement Directive 2014/24/EU, policymakers have ordered the inclusion of various criteria, such as the price, life-cycle costs, environmental, and social aspects, in the evaluation of tenders for public construction projects. Consequently, the relevance of non-monetary award criteria has gained significant value. However, the established evaluation formulas, which are used to obtain the best value for money procurement, have resulted in legal disputes. The existing evaluation formulas exhibit mathematical weaknesses, wherein scoring indices do not express economic efficiency adequately. Thus, a conflict is observed between the political requirement of non-monetary award criteria and their evaluation by contracting authorities. To overcome such dilemma, an extensive literature review is conducted. Specifically, this study explores the essential problems of existing evaluation formulas and develops a more reliable method. The technique from the field of efficiency analysis, i.e., Data Envelopment Analysis (DEA), is adopted in this study. For contract awarding, the DEA is extended by introducing a decision theoretical framework. For public procurement, the proposed method combines two advantages. First, the proposed method ensures the derivation of a robust tender ranking given that with respect to clients’ preferences, irrelevant and insufficiently tailored tenders do not influence the scoring. Second, the proposed method supports the intention of policy makers to promote public goals, such as sustainable aspects. By disclosing the strengths and weaknesses of bidders with respect to their competitors, all bidders can obtain a precise overview of their performance regarding the award criteria. In sum, the proposed method allows a targeted improvement of certain criteria values in future tenders and consequently leads to an enhancement of public goals.
