Published: December 2020

Background and Purpose: Herein, we describe a rare case of fatal cerebral phaeohyphomycosis by Cladophialophora bantiana in an immunocompetent individual without any underlying risk factors.Case report: A 55-year-old female presented with a short history of fever for 1 month, as well as headache, sudden onset of right-sided upper and lower limb weakness, and loss of speech for 10 days. Contrast-enhanced magnetic resonance imaging scan revealed large, peripherally enhancing, well-defined, cystic, space-occupying, axial lesion in the left parietal lobe with a mass effect. The patient was subjected to craniotomy, and the drained pus revealed pigmented septate hyphae in potassium hydroxide mount examination, which was identified as Cladophialophora bantiana. The patient was started on amphotericin B and voriconazole. However, she developed acute respiratory infection leading to multi-organ failure and death on day 27 post-operation.
Conclusion: In the absence of comparative trials owing to the rarity of the disease, the radical resection of lesion, drainage of pus, and prolonged targeted antifungal therapy with close postoperative radiological surveillance are the therapeutic measures of choice for patients with brain abscess caused by phaeoid fungi.
Innovative Early Sequenced Multidrug Therapy for Sars-Cov-2 (Covid-19) Infection to Reduce Hospitalization and Death
Authors: McCullough Peter 
Published: December 2020

The SARS-CoV-2 virus spreading across the United States has led to surges of COVID-19 hospitalizations and death. It is clear that randomized trials of single drugs will fail to resolve the crisis due to the complex and multifaceted nature of COVID-19 illness including viral mediated organ damage, cytokine storm, and thrombosis. Patients endure long untreated periods before succumbing to hospitalization and delayed treatment. Thus, early innovative, sequenced multidrug regimens have the best chance of success and are prudent as the next direction in randomized trials and advanced practice. Early management includes: 1) environmental efforts to reduce reinoculation and maintain isolation in the home, 2) combination anti-infective therapy, 3) corticosteroids, 4) antiplatelet agents/antithrombotics, 5) supportive care including supplemental oxygen, monitoring, and telemedicine. Randomized trials of novel oral therapies have not delivered tools of physicians to combat the pandemic in practice. Thus, an immediate pivot from single drug to innovative sequenced multidrug regimens is required as the only strategy to deal with current acute cases of COVID-19 with the aim of avoiding hospitalization and death.

Published: December 2020

Background: Magnetic resonance imaging (MRI) is currently regarded as the reference standard for the diagnosis and evaluation of internal derangements of the knee and shoulder girdle. This study aimed to evaluate traumatic injuries of the knee and shoulder joint ligaments by MRI and classify the most common ligament injuries.	Methods and Results: This study included 50 patients, who were presented in the Radiology Department of Modern Medical Center in Khartoum, in the period from October 2019 to January 2020. The sample was divided into two groups: shoulder joint group (Group 1, n=30) with an age range between 16 and 74 years and knee joint group (Group 2, n=20) with an age range between 16 and 77 years. The age group most affected with shoulder (46.7%) and knee joint (25%) injuries was 46-65 years. The injuries of the shoulder (40%) and knee joints (55%) were common in patients with body weight ranging from 71-80kg and >81kg, respectively. Different grades of partial meniscus tear of both shoulder and knee joints were noted as Grades 1 and 2 in 8.7% of cases, Grade 2 - 13%, Grades 2 and 3 - 34.8%, and Grade 3 - 30.4%. There were incidences of 27.3%, 0%, 54.5%, 15.20, 0%, and 3% for anterior cruciate ligament, posterior cruciate ligament, medial meniscus C-shape (M Me C), lateral meniscus C-shape (L Me C), MCL, and LCL tears in the knee joints of the affected patients.	Conclusion: MRI revealed that injuries to the shoulder and knee joints were common in patients with body weight ranging from 71-80kg and >81kg, respectively. Different grades of partial meniscus tear of the shoulder and knee joints were noted though Grades 2 and 3 partial tears were the most common finding. Finally, it was noted that in the knee joints of the affected patients, the M Me C shaped tear was the major type of tear.
Mammographic Density Errors during Interpretation of Breast Examinations
Authors: Pavlova Tamara , Vasilyev Aleksandr , Buromsky Ivan 
Published: December 2020

Background: This article discusses errors that may occur when radiologists deal with mammographic density (MD) and present their performance analysis in Russia. Methods and Results: The authors of this report have analyzed 24,485 mammographic reports for 20,000 female patients (aged 29-85 years) that were made in various healthcare facilities in the Russian Federation. In 249(1.7%) mammographic exam reports, we observed a wrong MD interpretation.	Conclusion: Diagnostic errors during mammographic examination occur because the radiologists lack theoretical knowledge about MD. This lack, in turn, results in a decrease in the quality of medical care provided for female patients and an increase in the number of diagnostic iatrogeny.

Abstract
Background/Objective: The aim of this study is to detect the prevalence of metabolic syndrome (MS) and its components in type B aortic dissection patients. This study assessed the association of MS and its component with type B aortic dissection in Chinese patients.Methods: This cross-sectional prospective observation study consisted of 445 patients who were first diagnosed with type B aortic dissection. Demographic information, clinical symptoms and laboratory parameters were collected using a standard form.Results: Among the 445 TBAD patients 38.4% had MS. Hypertension was present in 78.2% of all TBAD patients. Hypertension, high fasting glucose and obesity were the most common combination of metabolic abnormalities (93%, 79.5% and 63.2%) in the TBAD patients, and a same phenomenon was seen in acute TBAD patients. But among chronic TBAD patients the most frequent individual components were hypertension, hyper- triglyceride and high fasting glucose (92.6%, 75%, and 70.6%). Presence of two or more components of the metabolic syndrome was common: 22.7% had one component, 31.9% had two components, 24.9% had three components, 10.8% had four components and 3.1% had five components. In TBAD, hypertension, obesity, triglycerides and FBG (fasting blood-glucose) were main risk factors for MS.ConclusionThis is the first study provided information on the prevalence and components of MS in the initial TBAD patients. Hypertension, high fasting glucose and obesity were the most common combination of metabolic abnormalities in TBAD patients.

Abstract
Background: Ferroptosis is a new form of regulated cell death (RCD), and its emergence has provided a new approach to the progression and drug resistance of breast cancer (BRCA). However, there is still a great gap in the study of ferroptosis-related genes in BRCA, especially luminal-type BRCA patients.Methods: We downloaded the mRNA expression profiles and corresponding clinical data of BRCA patients from the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) and The Cancer Genome Atlas (TCGA) databases. Then, we built a prognostic multigene signature with ferroptosis-related differentially expressed genes (DEGs) in the METABRIC cohort and validated it in the TCGA cohort. The predictive value of this signature was investigated in terms of mutations, copy number variations (CNVs), the immune microenvironment, tumor purity, related pathway and the probability of a response to immunotherapy and chemotherapy.Findings: The patients were divided into a high-risk group and a low-risk group by the ferroptosis-associated gene signature, and the high-risk group had a worse overall survival (OS). The risk score based on the 10 ferroptosis-related gene-based signature was determined to be an independent prognostic predictor in both the METABRIC and TCGA cohorts (HR, 1.41, 95% CI, 1.14-1.76, P = 0.002; HR, 2.19, 95% CI, 1.13-4.26, P= 0.02). Gene set enrichment analysis indicated that the term “cytokine-cytokine receptor interaction” was enriched in the high risk score subgroup. Moreover, the immune infiltration scores of most immune cells were significantly different between the two groups, and the low-risk group was much more sensitive to immunotherapy and chemotherapy. In addition, we found that amplifications on chromosome 12 accompanied by the deletion of chromosome 21 were enriched in the high-risk subgroup. Pathway score results suggest that the ferroptosis-related gene-based signature show differences in most breast cancer-associated phenotypes. Finally, a nomogram incorporating a classifier based on the 10 ferroptosis-related genes, tumor stage, age and histologic grade was established. This nomogram showed a favorable discriminating ability and might contribute to clinical decision-making for luminal-type breast carcinoma.

Published: December 2020

Abstract
In recent years, the amount of water and sediment in the Yellow River Basin has dropped drastically. This paper selected 125 rainfall and flood data points from 1965 to 2015, combined hydrological methods and mathematical statistics to analyze the hydrological factors and runoff generation mechanism, and combined the underlying surface conditions of the Gushanchuan Basin. The characteristics of change revealed the temporal and spatial variation characteristics and related factors of the runoff generation mechanism in the basin. The results showed that the Gushanchuan Basin is still dominated by HOF runoff, but the runoff generation mechanism has also changed with changes in the underlying surface, which are reflected in increased runoff components, the reduced proportion of HOF runoff, and the increased proportion of saturation-excess overland flow (SOF) runoff and mixed runoff. We analyzed the variation law of underlying surface in the basin, which indicated that the increase in the forest grass area was the main factor affecting changes in the watershed runoff generation mechanism. This research will enable a deeper understanding of the runoff generation mechanism of the main soil erosion areas in the Loess Plateau, and reveal variations in the runoff generation mechanism in the Yellow River.

Published: December 2020

Abstract
The widespread implementation of municipal wastewater treatment and reuse must first ensure the safety of reused wastewater. The effluent of the municipal wastewater treatment plant contains a large amount of dissolved organic matter (DOM), which adversely affects the reuse of wastewater. In this study, the ultrafiltration (UF) + reverse osmosis (RO) process was used to treat the secondary effluent from wastewater treatment plants. The relationship between the removal performance, membrane fouling of the UF + RO process, and DOM removal characteristics of influent were studied. The results show that DOM can be removed effectively by UF + RO process. The UF mainly removes DOM with a molecular weight greater than 10 kDa, while RO has a significant removal effect on low-molecular-weight DOM, which mainly causes UF and RO membrane fouling. The UF + RO process has a significant removal rate on fulvic acid, humic acid, tyrosine, and tryptophan, and the order is humic acid &gt; fulvic acid &gt; tyrosine &gt; tryptophan. Fulvic acid contributed the most to the UF membrane fouling, while fulvic acid and protein-like proteins contributed mainly to the RO membrane fouling.
Zinc-bearing dust derived non-toxic mixed iron oxides as magnetically recyclable photo-Fenton catalyst for degradation of dye

Published: December 2020

Abstract
In this paper, comprehensive utilization of hazardous zinc-bearing dust for preparation of non-toxic mixed iron oxides as a magnetically recyclable photo-Fenton catalyst for degradation of dye by a facile solid state reaction process was proposed. The as-prepared samples were characterized by X-ray diffraction (XRD), Raman spectra, ultraviolet and visible (UV-Vis) spectra and Physical Property Measurement System (PPMS), and the degradation performance of as-prepared catalysts was also tested and analyzed. The results show that spinel ferrite coexisting with or without Fe2O3 was the predominant phase in the as-prepared samples, which were confirmed by Raman analysis. The as-prepared samples presented high degradation efficiency (about 90%) of rhodamine B (RhB) in the presence of hydrogen peroxide (H2O2) with visible light irradiation, owing to the synergistic effect of photocatalyst reaction and Fenton-like catalyst reaction during the degradation process. The mixed iron oxides also presented stable structure and exhibited excellent reusability with a degradation efficiency of 87% after the fifth cycle of reuse. Importantly, the heavy metals in the zinc-bearing dust could be fixed in the stable spinel structure. This paper could provide a simple approach for comprehensive utilization of zinc-bearing dust to synthesize non-toxic mixed iron oxides as a magnetically recyclable photo-Fenton catalyst for degradation of dye.

Published: December 2020

A pesquisa propõe-se a analisar a contribuição do turismo na realização de práticas ambientais pelos empreendimentos turísticos da Rota de Turismo Rural denominada Pelotas Colonial, situada no município de Pelotas, no Estado do Rio Grande do Sul/Brasil. Trata-se de uma pesquisa descritiva, de caráter quali-quantitativo, na qual a entrevista estruturada e a observação foram os instrumentos de coleta dos dados. As entrevistas foram realizadas com dez responsáveis, dos quatorze empreendimentos pertencentes à Rota Pelotas Colonial, abordando a gestão dos resíduos sólidos nesses estabelecimentos. Por fim percebe-se que, apesar dos entrevistados considerarem que a educação ambiental é a mais relevante contribuição do turismo, notou-se a falta de conhecimento quanto às ações ambientais e como desenvolvê-las, além de conhecimentos teóricos e normativos a respeito do meio ambiente.

Precarização do trabalho no setor de eventos: um estudo inicial sobre os impactos para os trabalhadores e empresas
Authors: De Oliveira Silva Marcella , Bantim Natasha , Maciel Costa Maria Angélica 
Published: December 2020

Esse trabalho tem como objetivo discutir a precarização nas relações de trabalho em um dos ramos mais relevantes do turismo: o setor de eventos. Apesar de ocupar posição econômica estratégica e proporcionar visibilidade dos destinos no mercado global, o setor se mantém, em grande parte, através de relações de trabalho terceirizadas, temporárias e informais. Essas relações são advindas do modelo financeiro internacional, de acumulação flexível do capital, onde o contrato de trabalho com todos os direitos e obrigações previamente definidos e inalterados ao longo de sua duração, vem sendo trocado por modelos menos rígidos, a partir da chamada ‘reestruturação produtiva’. Para exemplificar essas relações, foi analisada uma empresa localizada no Rio de Janeiro (RJ), especializada em orientação de público em eventos e seus contratados. Verificou-se a percepção de clientes e funcionários sobre os serviços prestados e a percepção dos trabalhadores freelancers sobre a contratação e estratégias de capacitação. Identificou-se elementos pouco criteriosos na contratação dos funcionários e no treinamento destes, demonstrando fortes indícios de precarização nas relações trabalhistas estabelecidas entre empresa e trabalhadores, incluindo remuneração com valores baixos e longas jornadas de trabalho. Apesar disso, a empresa parece não se importar com as consequências na qualidade do serviço prestado, já que o regime de terceirização acaba mitigando a percepção da responsabilidade pelo serviço prestado e, consequentemente, gerando poucos danos à imagem da empresa perante o público.
