Published: December 2021

Objectives:
To describe the findings of incidental asymptomatic COVID-19 infection on FDG PET-CT using a case–control design.

Methods:
Incidental pulmonary findings suspicious of asymptomatic COVID-19 infection on FDG PET-CT were classified as a confirmed (positive RT-PCR test) or suspected case (no/negative RT-PCR test). Control cases were identified using a 4:1 control:case ratio. Pulmonary findings were re-categorised by two reporters using the BSTI classification. SUV metrics in ground glass opacification (GGO)/consolidation (where present), background lung, intrathoracic nodes, liver, spleen and bone marrow were measured.

Results:
7/9 confirmed and 11/15 suspected cases (COVID-19 group) were re-categorised as BSTI 1 (classic/probable COVID-19) or BSTI 2 (indeterminate COVID-19); 0/96 control cases were categorised as BSTI 1. Agreement between two reporters using the BSTI classification was almost perfect (weighted κ = 0.94). SUVmax GGO/consolidation (5.1 vs 2.2; p &lt; 0.0001) and target-to-background ratio, normalised to liver SUVmean (2.4 vs 1.0; p &lt; 0.0001) were higher in the BSTI 1 & 2 group vs BSTI 3 (non-COVID-19) cases. SUVmax GGO/consolidation discriminated between the BSTI 1 & 2 group vs BSTI 3 (non-COVID-19) cases with high accuracy (AUC = 0.93). SUV metrics were higher (p &lt; 0.05) in the COVID-19 group vs control cases in the lungs, intrathoracic nodes and spleen.

Conclusion:
Asymptomatic COVID-19 infection on FDG PET-CT is characterised by bilateral areas of FDG avid (intensity &gt; x2 liver SUVmean) GGO/consolidation and can be identified with high interobserver agreement using the BSTI classification. There is generalised background inflammation within the lungs, intrathoracic nodes and spleen.

Advances in knowledge:
Incidental asymptomatic COVID-19 infection on FDG PET-CT, characterised by bilateral areas of ground glass opacification and consolidation, can be identified with high reproducibility using the BSTI classification. The intensity of associated FDG uptake (&gt;x2 liver SUVmean) provides high discriminative ability in differentiating such cases from pulmonary findings in a non-COVID-19 pattern. Asymptomatic COVID-19 infection causes a generalised background inflammation within the mid-lower zones of the lungs, hilar and central mediastinal nodal stations, and spleen on FDG PET-CT.

Pandemia: czas lęków, modlitwy i przeobrażeń społecznych
Authors: Marciniak Katarzyna 
Published: December 2021

Artykuł analizuje zachowania społeczne, które charakteryzowały społeczność polską w obliczu zagrożenia epidemicznego w wiekach poprzednich jak i współcześnie. Pokazuje jak lęk przed chorobą ograniczał i ogranicza funkcjonowanie społeczeństwa polskiego w czasie epidemii. Wskazuje na podobne zachowania Polaków zarówno w wieku XVII jak i współcześnie jednocześnie akcentując różnice, jakie zaistniały na przestrzeni wieków. Tu przede wszystkim zwraca uwagę na różnice, które zaszły w postawach religijnych: gdzie w wiekach poprzednich czas morowego powietrza charakteryzowała zwiększona religijność Polaków oraz powszechne modlitwy w miejscach świętych a obecnie powszechne dostęp do miejsc kultu został poważnie ograniczony, dotyczy to przede wszystkim miejsc pielgrzymkowych, które w obliczu pandemii zamknęły swoje świątynie przed pielgrzymami.

The Effect of the Paycheck Protection Program and Financial Reporting Standards on Bank Risk-Taking
Authors: Ballew Hailey B. , Nicoletti Allison , Stuber Sarah B. 
Published: December 2021

This paper examines the consequences of the paycheck protection program (PPP) for bank risk-taking and whether the shift to the current expected credit loss (CECL) model moderates this effect. We find that the extent of a bank’s PPP participation is associated with relatively greater changes in risk-taking outside of the PPP. We also show that this effect is concentrated in banks that have not early adopted the CECL model and banks with timelier pre-PPP loan loss provisions, suggesting that timelier loan loss recognition constrains risk-taking incentives. Overall, our findings provide insight into the indirect consequences of government stimulus programs administered through banks and the role of accounting in constraining bank risk-taking.

Gendered Vocational Identities – Female Students' Strategies for Identity Formation During Workplace-Based Learning in Male-Dominated Work
Authors: Ferm Lisa , Gustavsson Maria 
Published: December 2021

Purpose: This article investigates female vocational students' strategies for becoming part of a workplace community, what these strategies are and how they are tied to the formation of vocational identities within male-dominated industrial work. Of particular interest is how female students enrolled on Swedish upper secondary industrial programmes experience workplace-based learning at industrial workplaces as part of their vocational education. The theoretical framework derives from Wenger's concept of community of practice, but his theoretical concept does not explicitly include gender dimensions. Therefore, the concept of community of practice is also combined with Paechter's assumption of gender, whereby femininity and masculinity can be considered as different communities of practice. Methods: The article draws on evidence from a Swedish study based on interviews with 20 female students enrolled on the industrial programme at six upper secondary schools. In this vocational programme, there is a distinct gender distribution and only a small minority of the students on the programme are girls. In the analysis, the focus is on the female students' strategies used during workplace-based learning to become part of the work community which consists almost exclusively of male workers.Findings: The female students deliberately negotiated vocational identities as female industrial workers to become accepted in the male-dominated work community. The findings highlight three specific strategies that the female students used: Acting like gender does not matter, acting like boys (not like drama queens), and acting tough and joking around. The female students' strategies were part of – and tied to – a complex vocational identity formation process that featured contradictory requirements. By taking individual responsibility, they identified relevant information for becoming industrial workers and chose to act like boys. The female students saw no problem with being a girl, yet they struggled with implicit, diffuse and hidden gender structures and prejudices in the male-dominated industrial companies. Nevertheless, they strived for what they perceived to be an attractive vocational identity as industrial workers; it was an alternative, atypically feminine way of being that attracted the female students. Conclusions: The study concludes that female students mostly rely on their individual agency when interacting with others in the male-dominated workplace community. A "gendered vocational identity" is formed which shows that the identity formation of female students is a complex double process, in which vocational and gender identities are formed simultaneously and in parallel within the male-dominated workplace.
Correlation of breast cancer microcirculation construction with tumor stem cells (CSCs) and epithelial-mesenchymal transition (EMT) based on contrast-enhanced ultrasound (CEUS)
Authors: Leng Xiaoling , Huang Guofu , Li Siyi , Yao Miaomiao , Ding Jianbing , Ma Fucheng 
Published: December 2021

Objective
This study is to explore the correlation between the contrast-enhanced ultrasound (CEUS) characteristics of breast cancer and the epithelial-mesenchyme transformation (EMT).

Methods
Totally 119 patients of breast cancer underwent CEUS. Tissues in the active area were collected and subjected to the immunohistochemical detection, PT-PCR and Western blot. Correlation analysis was conducted between the clinical pathological parameters and the CEUS indicators.

Results
The expression levels of CD44, N-cadherin, and β-catenin in breast cancer tissues were higher than those in adjacent tissues (P<0.05). However, the expression levels of CD24 and E-cadherin in breast cancer tissues were lower than those in adjacent tissues (P<0.05). There was no significant difference in E-cadherin mRNA and Vimentin levels between cancer and adjacent tissues (P>0.05). The expressions were up-regulated in the CSCs, with higher histological grade, lymph node metastasis, and negative estrogen receptor (ER) expression. Smaller breast tumors, with no lymph node metastasis, lower clinical stage, and positive ER expression, tended to exhibit the up-regulated epithelial phenotype. Breast tumors, with high histological grade, lymph node metastasis, high clinical staging grade, and negative ER expression, tended to exhibit the up-regulated interstitial phenotype. The peak intensity of the time-intensity curve (TIC) for the CEUS was positively correlated with the CSC marker CD44 and the interstitial phenotype marker N-cadherin. The starting time of enhancement was negatively correlated with the N-cadherin. Area under the curve was positively correlated with the expression of CD44 and N-cadherin, while negatively correlated with the epithelial phenotype marker β-catenin. The time to peak was negatively correlated with the interstitial phenotypes Vimentin and N-cadherin, with no correlation with the E-cadherin or β-catenin.

Conclusion
Breast cancers show the enlarged lesions after enlargement and perfusion defect for the CEUS. The fast-in pattern, high enhancement, and high perfusion in the TIC are correlated with the CSCs and EMT expressions, suggesting poor disease prognosis.
Women’s perceptions and experiences of reproductive coercion and abuse: a qualitative evidence synthesis
Authors: Moulton Jessica E. , Corona Martha Isela Vazquez , Vaughan Cathy , Bohren Meghan A. 
Published: December 2021

Background
Reproductive coercion and abuse is a major public health issue, with significant effects on the health and well-being of women. Reproductive coercion and abuse includes any form of behaviour that intentionally controls another person’s reproductive choices. The aim of this qualitative evidence synthesis is to explore women’s experiences of reproductive coercion and abuse globally, to broaden understanding of the different ways reproductive coercion and abuse is perpetrated, perceived and experienced across settings and socio-cultural contexts.

Method
We searched Medline, CINAHL and Embase for eligible studies from inception to 25th February 2021. Primary studies with a qualitative study design that focused on the experiences and perceptions of women who have encountered reproductive coercion and abuse were eligible for inclusion. Titles and abstracts, and full texts were screened by independent reviewers. We extracted data from included studies using a form designed for this synthesis and assessed methodological limitations using CASP. We used Thomas and Harden’s thematic analysis approach to analyse and synthesise the evidence, and the GRADE-CERQual approach to assess confidence in review findings.

Results
We included 33 studies from twelve countries in South Asia, the Asia Pacific, North America, South America, Africa and Europe. Most studies used in-depth interviews and focus group discussions to discuss women’s experiences of reproductive coercion and abuse. Reproductive coercion and abuse manifested in a range of behaviours including control of pregnancy outcome, pregnancy pressure or contraceptive sabotage. There were a range of reasons cited for reproductive coercion and abuse, including control of women, rigid gender roles, social inequalities and family pressure. Women’s different responses to reproductive coercion and abuse included using covert contraception and feelings of distress, anger and trauma. Across contexts, perpetration and experiences of reproductive coercion and abuse were influenced by different factors including son preferences and social exclusion.

Conclusions
We reflect on the importance of socio-cultural factors in understanding the phenomenon of reproductive coercion and abuse and how it affects women, as well as how the mechanisms of power and control at both individual and societal levels work to perpetuate the incidence of reproductive coercion and abuse against women.

BackgroundHuman immunodeficiency virus (HIV) affects a highly significant number of people and is responsible for the deaths of many people in sub-Saharan African countries alone. The best prevention method for this virus is through consistent condom utilization which can help to prevent drug-resistant HIV infection and acquisition of new infection. Therefore, this study aimed to assess consistent condom utilization and associated factors among HIV-positive individuals attending an antiretroviral therapy clinic at Pawi general hospital, North West Ethiopia in 2020.MethodsAn institutional based cross-sectional study was conducted among 419 HIV-positive individuals who have follow-up in the Pawi general hospital antiretroviral therapy clinics, from January to February 2020. The study subjects were reached using a systematic sampling technique and data were collected using a pretested and structured questionnaire. Data entry and analysis were performed using epi-data version 3.1 and SPSS version 23 respectively. Binary and multivariable analyses with a 95% confidence level were performed. In the final model, variables with P < 0.05 were considered statistically significant.ResultsA total of 419 antiretroviral therapy study participants were participated in the study with a response rate of 100%. In this finding, the consistent condom utilization rate was 49.2% [95% CI: 42.2–56.5%]. After controlling for possible confounding factors, the results showed that place of residence [AOR = 2.16, 95% CI: 1.05, 4.45], marital status [AOR = 0.19, 95%CI: 0.05, 0.67], number of partners [AOR = 0.19, 95% CI: 0.07, 0.55] and level of education [AOR = 5.33, 95% CI: 1.57, 18.08] were associated factors of consistent condom utilization.ConclusionConsistent condom utilization among HIV-positive clients attending antiretroviral therapy clinics at Pawi general hospital was low. Residence, marital status, level of education and number of partners were significantly associated factors of consistent condom use. Health education program and counseling services should be started to increase knowledge about way of transmission and appropriate use of condoms, increase self-efficacy towards condom use and reduction in the number of sexual partners.
El '72 en Santa Fe: contienda política y un "azo" en la memoria
Authors: Raina Andrea Carla 
Published: December 2021

En el marco del ciclo de protesta que se desplegó en Santa Fe entre los años 1969-1973, proponemos analizar las acciones de diferentes actores movilizados que hacia el año 1972 constituyeron episodios de contienda política (McAdam, Tarrow, Tilly, 2005). Bajo el prisma conceptual de la triada actores-acciones-identidades estudiaremos este momento histórico empleando una metodología cualitativa de análisis de fuentes escritas y orales. Contamos con el periódico local El Litoral, volantes y comunicados de organizaciones políticas y sindicales, entrevistas orales y testimonios provenientes de memoriales producidos en torno al aniversario de algunos de los hechos. Cronológicamente los acontecimientos que estudiamos van desde el intento de secuestro del intendente Conrado Puccio por Montoneros en febrero de 1972 y el impacto hacia el interior de la organización político-militar (OPM); la Lucha por el Medio Boleto llevado adelante por estudiantes secundarios y el paro activo realizado por trabajadores municipales nucleados en el gremio de ASOEM que provocó la destitución del intendente Conrado Puccio por un interventor policial -Francisco Sgabassi- y culminó en el recordado "Manzanazo" a fines de junio de 1972.

Authors: Zhou Zi-Jing , Wang Zhen-Xing , Han Xiao-shuai , Pu Jun-Wen 
Published: December 2021

Abstract
Lightweight materials with high electrical conductivity and hydrophobic mechanical properties are ideal materials for electromagnetic interference (EMI) shielding. Herein, the conductive composites with great EMI shielding effectiveness (SE) were successfully obtained by introducing multi-walled carbon nanotube (CNT) and polydimethylsiloxane (PDMS) based on the original structure of natural wood (NW). CNT@PDMS/NW composites were prepared via vacuum-pulse impregnation method and characterized by Fourier transform infrared (FTIR), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) patterns, hydrophobicity analysis, and EMI shielding performance. As demonstrated, CNT nanosheets were successfully inserted into wood matrices, and hydrogen bonding between CNT nanosheets and cellulose nanofibers induced the fabrication of CNT@PDMS/NW composites. CNT@PDMS/NW composites exhibited excellent EMI SE values of 25.2 dB at the X-band frequency.

Conformal vector fields on almost co-Kähler manifolds
Authors: De Uday Chand , Suh Young Jin , Chaubey Sudhakar K. 
Published: December 2021

Abstract
In this paper, we characterize almost co-Kähler manifolds with a conformal vector field. It is proven that if an almost co-Kähler manifold has a conformal vector field that is collinear with the Reeb vector field, then the manifold is a K-almost co-Kähler manifold. It is also shown that if a (κ, μ)-almost co-Kähler manifold admits a Killing vector field V, then either the manifold is K-almost co-Kähler or the vector field V is an infinitesimal strict contact transformation, provided that the (1,1) tensor h remains invariant under the Killing vector field.
Photoluminescence enhancement with all-dielectric coherent metasurfaces

Published: December 2021

Abstract
Mie resonances have recently attracted much attention in research on dielectric metasurfaces, owning to their enriched multipole resonances, negligible optical loss, and efficient light emitter integration. Although there is a rapid advancement in this field, some fundamental developments are still required to provide a simpler and more versatile paradigm for photoluminescence (PL) control. In this work, we proposed that an all-dielectric coherent metasurface can engineer the PL response by tuning the array size. Such PL manipulation is attributed to the collective Mie resonances that mediate the inter-unit interactions between unit elements and alter the PL intensity. Metasurfaces with different chip sizes are utilized to explore the array size effect on the collective Mie resonances, field enhancement, and Q-factor in TiO2 metasurfaces. Incorporating the all-dielectric coherent metasurface with fluorescent photon emitters, we performed the dependence of PL enhancement on array size, which achieves an enhancement factor of ∼10 at the central area of a 90 × 90 μm2 TiO2 metasurface array. These findings provide an additional degree of freedom to engineer the near-field confinement and enhancement, allowing one to manipulate incoherent photon emission and tune light–matter interaction at the nanoscale.
