Experiencing service learning partnership: A human development perspective of community members
Authors: Mtawa Ntimi N , Fongwa Samuel N
Published: December 2020

Service–learning has, arguably, gained significant currency as a pedagogical and engagement mechanism within the broader discourse of universities and their role in community development. However, less emphasis has been placed on the human development dimensions of service–learning for community members, with the focus largely being on students’ experiential learning and other academic outcomes for the university. Though usually conceived as an integral part in university–community partnerships, community members’ role in the conception and implementation of service–learning initiatives is from a peripheral position. In this paper, we interrogate this lacuna by applying core tenets of the human development approach to document the experiences and perceptions of community members within a university–community service learning partnerships. From the analysis of qualitative data n = 22, we demonstrate that while service–learning enhances agency, it continues to operate within a historical context and contemporary political economy of South Africa, which obscure community members’ active participation and empowerment towards inclusive and sustainable valued outcomes.

Published: December 2020

Background

The characteristics of patients who have repeated compulsory psychiatric admissions are largely unknown.

Aims

To investigate the frequency and risk factors for repeated emergency compulsory psychiatric admission (ECPA); and to identify targets for interventions to reduce repeated ECPA.

Method

Data were collected from a database of electronic patient files (EPFs) held by three psychiatric emergency services (PES) in the Netherlands. Analyses were based on the data for adult patients (aged 18–75 years) with a first PES contact in 2010–2015. Using descriptive statistics and regression analysis, we studied the associations between baseline patient factors and repeated ECPA and time to readmission, within a 2-year follow-up period.

Results

We included 6059 patients: 15.6% had two or more ECPAs. In total, 66% of second ECPAs had occurred within 6 months of the first. About 30% of all ECPAs were repeated ECPAs. Two baseline factors were associated with a higher frequency of a second ECPA: history of receiving any mental healthcare treatment, whether in-patient or out-patient or both, and a lower level of self-care. Three were associated with a lower frequency: ethnicity (other than Dutch), older age and suicidality. Lower Global Assessment of Functioning (GAF) scores and housing problems were associated with a shorter time to compulsory readmission and persistent psychiatric problems with a longer time to compulsory readmission.

Conclusions

We found that 15.6% of patients had two or more ECPAs. Two-thirds of the second ECPAs had occurred within 6 months of the first. Like earlier studies, the risk factors we identified suggest that interventions to reduce the risk of repeated compulsory psychiatric admission should seek to improve self-care, general daily functioning and homelessness.
Departmental Dystopia
Authors: Labridy-Stofle Corine
Published: December 2020

This essay seeks to add a set of novellas written by Raphaël Confiant between 1994 and 1997 to the ongoing conversation surrounding the Éloge de la créolité and its controversial legacy. In the nearly thirty years since its publication, the Éloge and its authors have been dispraised for their monomaniacal concern for the past and their phallocentric disregard for women’s critical role in the transmission of Antillean culture. Far from suggesting that these accusations are ill-founded, this essay contends that Confiant responded to the critiques and confronted the Éloge’s blindspots in his Trilogie tropicale. These exuberant works, which think through the effects of modernity, globalization, and cultural domination on contemporary Martinique, have been largely ignored, perhaps because they do not follow the poetic principles outlined in the Éloge. Rather than treating them apart from other créoliste writings, this essay proposes that they constitute a self-reflexive moment in Confiant’s oeuvre.
Inside and Outside the Exhibition Space
Authors: Castellano Carlos Garrido , Lopez Magdalena
Published: December 2020

This essay deals with issues of citizenship, artistic labor, and belonging in the context of the Dominican Republic. It examines the collaborative work of the Colectivo Quintapata to understand how artistic collaboration is used as a way for generating social transformation and reaching audiences beyond the artistic medium. Analyzing art installations, public interventions, and socially engaged art pieces produced by Quintapata between 2009 and 2014, this essay argues that artistic collaboration works in the case of Quintapata, not so much as a formula but rather as a flexible tool employed to face situations of economic and institutional precariousness, extending the outcomes of each project beyond its original temporality and audience.
Montreal 1968 and the Last Colonial Generation
Authors: Hudson Peter James
Published: December 2020

Held at Montreal’s McGill University from 11 to 14 October 1968, the “Congress of Black Writers: Toward the Second Emancipation—the Dynamics of Black Liberation” was dubbed the largest Black Power conference ever held outside the United States. In Moving Against the System: The 1968 Congress of Black Writers and the Making of Global Consciousness, David Austin has compiled the surviving transcripts of this historic gathering, including the speeches by Walter Rodney, C. L. R. James, Stokely Carmichael, and Richard B. Moore, and he provides an extended introduction locating Montreal within the global politics of the late 1960s. This essay considers Moving Against the System as an archive of black and Caribbean history, examining both the debates that occurred among the participants of the conference and Austin’s role as an archivist and interpreter of Montreal’s radical past.
Moving Against the System
Authors: Alagraa Bedour
Published: December 2020

This essay views David Austin’s Moving Against the System: The 1968 Congress of Black Writers and the Making of Global Consciousness through the prism of dread history as a way of considering how this text can be understood as a chronicling of the congress while also acting as a harbinger of the radical methodological impulses of dread history. Drawing on the speeches and proceedings detailed in the anthology, while also surveying the broader moment of the “global 1968,” the essay explores some of the antagonisms that underpinned the congress to examine the broader antagonisms of this moment, which include the “absented presence” of black women radicals. The essay ends with a meditation on the stakes of such a project for black Canada and its often veiled (but no less insurgent) dread-historical contributions to the global 1968 and current struggles for liberation.
Planar cell polarity: moving from single cells to tissue-scale biology
Authors: Mlodzik Marek
Published: December 2020

Planar cell polarity (PCP) reflects cellular orientation within the plane of an epithelium. PCP is crucial during many biological patterning processes and for organ function. It is omnipresent, from convergent-extension mechanisms during early development through to terminal organogenesis, and it regulates many aspects of cell positioning and orientation during tissue morphogenesis, organ development and homeostasis. Suzanne Eaton used the power of Drosophila as a model system to study PCP, but her vision of, and impact on, PCP studies in flies translates to all animal models. As I highlight here, Suzanne's incorporation of quantitative biophysical studies of whole tissues, integrated with the detailed cell biology of PCP phenomena, completely changed how the field studies this intriguing feature. Moreover, Suzanne's impact on ongoing and future PCP studies is fundamental, long-lasting and transformative.

IMPACT OF METEOROLOGICAL STORMS ON THE E-REGION OF THE IONOSPHERE IN 2017–2018
Authors: Borchevkina Olga , Karpov Ivan , Karpov Mikhail , Korenkova Nina , Vlasov Valery , Leshchenko Vladimir
Published: December 2020

The paper presents the results of observations of the sporadic Es layer during the period of meteorological disturbances in Kaliningrad in October 2017 and 2018 under quiet geomagnetic conditions. During the meteorological storms (October 29–30, 2017 and October 23–24, 2018), significant changes occurred in the dynamics of the Es-layer critical frequency. Observations of atmospheric and ionospheric disturbances in the Kaliningrad region show that the delay between the ionospheric response and the moment of maximum disturbances in atmospheric parameters is about 3 hours. These phenomena at the heights of the E-region might have been caused by propagation of acoustic-gravity waves generated by convective processes in the lower atmosphere during periods of a meteorological storm. Intensification of turbulent processes in the lower thermosphere leads to an increase in the atmospheric density and, accordingly, to higher recombination rates. This leads to a rapid decrease in the concentration of ions and, consequently, to a decrease in the critical frequency of the sporadic layer below the sensitivity threshold of ionosondes.

652. La construcción i apropiación de paisajes culturales: una ecología política histórica del Wallmapu/Araucanía, Chile.
Authors: Escalona Ulloa Miguel Antonio , Barton Jonathan Richard
Published: December 2020

El territorio de Wallmapu Araucanía desde su incorporación a la República de Chile como la Región de la Araucania, ha sido objeto de importantes transformaciones territoriales. Este artículo utiliza la perspectiva de la ecología política histórica para comprender cómo la construcción de paisajes culturales se convirtió en un dispositivo para ejercer el poder hegemónico. Estos paisajes de poder evolucionaron con el tiempo a medida que se establecieron diferentes demandas en este territorio: primero a partir del ‘Granero de Chile’ a finales del siglo XIX y luego bajo la explotación forestal del ‘Oro verde’ durante los siglos XX y XXI. Ambos paisajes han posibilitado la instalación de un sentido común dominante asociado al modernidad, progreso y desarrollo en Wallmapu/Araucanía, que ha influido en el conflicto Estado-Pueblo Mapuche.

A cost-efficient and low-complexity optical input/output (I/O) packaging solution is a substantial challenge for volume production of photonic integrated circuits. To address this, metamaterial fiber couplers are an attractive solution for integrated photonic devices especially for optical I/O, interfacing standard optical fibers to photonic chips. They offer the advantages of refractive index engineering to achieve better mode match as well as higher fabrication tolerances. Metamaterial waveguides, as a fundamental building block of these fiber couplers, have attracted tremendous attention in recent years. Here, we report on effective optical return loss control in Si metamaterial waveguide designs to achieve ultra-low reflection loss in CMOS-compatible silicon photonics implemented in a 300 mm production line. Low backscattering is a substantial consideration for a range of applications. Here, a return loss of better than

Published: December 2020

Biological measurements frequently involve measuring parameters as a function of time, space, or frequency. Later, during the analysis phase of the study, the researcher splits the recorded data trace into smaller sections, analyzes each section separately by finding a mean or fitting against a specified function, and uses the analysis results in the study. Here, we present the software that allows to analyze these data traces in a manner that ensures repeatability of the analysis and simplifies the application of FAIR (findability, accessibility, interoperability, and reusability) principles in such studies. At the same time, it simplifies the routine data analysis pipeline and gives access to a fast overview of the analysis results. For that, the software supports reading the raw data, processing the data as specified in the protocol, and storing all intermediate results in the laboratory database. The software can be extended by study- or hardware-specific modules to provide the required data import and analysis facilities. To simplify the development of the data entry web interfaces, that can be used to enter data describing the experiments, we released a web framework with an example implementation of such a site. The software is covered by open-source license and is available through several online channels.
Transferrin receptor regulates malignancies and the stemness of hepatocellular carcinoma-derived cancer stem-like cells by affecting iron accumulation
Authors: Xiao Chong , Fu Xi , Wang Yuting , Liu Hong , Jiang Yifang , Zhao Ziyi , You Fengming
Published: December 2020

Background

Iron metabolism is essential because it plays regulatory roles in various physiological and pathological processes. Disorders of iron metabolism balance are related to various cancers, including hepatocellular carcinoma. Cancer stem-like cells (CSCs) exert critical effects on chemotherapy failure, cancer metastasis, and subsequent disease recurrence and relapse. However, little is known about how iron metabolism affects liver CSCs. Here, we investigated the expression of transferrin receptor 1 (TFR1) and ferroportin (FPN), two iron importers, and an upstream regulator, iron regulatory protein 2 (IRP2), in liver hepatocellular carcinoma (LIHC) and related CSCs.

Methods

The expression levels of TFR1, FPN and IRP2 were analysed using the GEPIA database. CSCs were derived from parental LIHC cells cultured in serum-free medium. After TFR1 knockdown, ROS accumulation and malignant behaviours were measured. The CCK-8 assay was performed to detect cell viability after TFR1 knockdown and erastin treatment.

Results

TFR1 expression was upregulated in LIHC tissue and CSCs derived from LIHC cell lines, prompting us to investigate the roles of TFR1 in regulating CSCs. Knockdown of TFR1 expression decreased iron accumulation and inhibited malignant behaviour. Knockdown of TFR1 expression decreased reactive oxygen species (ROS) accumulation induced by erastin treatment and maintained mitochondrial function, indicating that TFR1 is critical in regulating erastin-induced cell death in CSCs. Additionally, knockdown of TFR1 expression decreased sphere formation by decreasing iron accumulation in CSCs, indicating a potential role for TFR1 in maintaining stemness.

Conclusion

These findings, which revealed TFR1 as a critical regulator of LIHC CSCs in malignant behaviour and stemness that functions by regulating iron accumulation, may have implications to improve therapeutic approaches.

Published: December 2020

The American Flamingo,Phoenicopterus ruber, is a charismatic bird distributed throughout the Caribbean, North and South America. Its wide distribution, the complexity of international monitoring due to its capacity for long-distance flying, and a focus mostly on local populations, make it difficult to understand the dynamics between sites. Here, we took advantage of the citizen eBird science project to present a global perspective on the distribution of the American Flamingo, and identify the potentially most important countries for breeding. We obtained 16,930 records for the Americas from the 1960s until October 2018, of which 9,283 could be used for our objectives. The eBird database indicated a considerable increase in the total number of records over the last decade (2010s), probably reflecting an increase in tourism facilities, research investment, technological advancement, interest in conservation, and the worldwide availability of eBird. We also observed a range extension in the Gulf of Mexico in the United States and a significant recolonization in the Florida Peninsula. The apparent range extension to the South is more likely to be linked to biases in the data; for example, in any given country the number of records might reflect either reporting efforts or actual numbers. eBird data confirmed that six countries host the main breeding colonies (Bahamas, Bonaire, Cuba, Ecuador, Mexico, and Venezuela). We suggest three additional countries as potential breeding areas for the species (Colombia, Curaçao, Turks and Caicos Islands) for which more field observations are necessary to support this possibility. This global appraisal of the distribution of the American Flamingo using citizen science data provides valuable information for national and international management and conservation programs such as the need to verify the species breeding status in areas where it appears to be expanding its distribution.
The SUMOylation pathway suppresses arbovirus replication in Aedes aegypti cells

Published: December 2020

Mosquitoes are responsible for the transmission of many clinically important arboviruses that cause significant levels of annual mortality and socioeconomic health burden worldwide. Deciphering the mechanisms by which mosquitoes modulate arbovirus infection is crucial to understand how viral-host interactions promote vector transmission and human disease. SUMOylation is a post-translational modification that leads to the covalent attachment of the Small Ubiquitin-like MOdifier (SUMO) protein to host factors, which in turn can modulate their stability, interaction networks, sub-cellular localisation, and biochemical function. While the SUMOylation pathway is known to play a key role in the regulation of host immune defences to virus infection in humans, the importance of this pathway during arbovirus infection in mosquito vectors, such as Aedes aegypti (Ae. aegypti), remains unknown. Here we characterise the sequence, structure, biochemical properties, and tissue-specific expression profiles of component proteins of the Ae. aegypti SUMOylation pathway. We demonstrate significant biochemical differences between Ae. aegypti and Homo sapiens SUMOylation pathways and identify cell-type specific patterns of SUMO expression in Ae. aegypti tissues known to support arbovirus replication. Importantly, depletion of core SUMOylation effector proteins (SUMO, Ubc9 and PIAS) in Ae. aegypti cells led to enhanced levels of arbovirus replication from three different families; Zika (Flaviviridae), Semliki Forest (Togaviridae), and Bunyamwera (Bunyaviridae) viruses. Our findings identify an important role for mosquito SUMOylation in the cellular restriction of arboviruses that may directly influence vector competence and transmission of clinically important arboviruses.
The affects of cement space thickness and material type with application of micro-CT scanner on marginal discrepancy of restoration
Authors: Mosharraf Mosharraf , Azizi Amir , Naziri Babak , Abolhasani Majid
Published: December 2020

Objective: Studies demonstrated that as one of the newly developed restorative materials, monolithic zirconia resolved several issues of zirconia restoration. Therefore, marginal accuracy and internal fit are necessary for clinical success and quality of restorations, and cement space may influence the marginal fit. Thus, the present research aimed to investigate the effects of the cement thickness and kind of restoration on the marginal discrepancy. Material and methods: In this study, 20 maxillary left first molars, prepared by DRSK Co., were used to fabricate a full crown. Two types of material included monolithic zirconia (Zolid) and Sintron were used to make a full crown. Samples from each group were scanned by dental laboratory 3D scanner and designed and processed using CAD-CAM. The samples were divided into four groups of five with 30- and 50- µm cement spaces. In order to assess the vertical marginal discrepancy, the crowns were fitted on their respective teeth without using any mediator and examined by a micro-CT scanner. Data were analyzed by SPSS software. Results: It has been found that marginal discrepancy in Sintron is higher than the discrepancy of monolithic zirconia. In fact, monolithic zirconia with 50-micron cement space exhibited the least marginal discrepancy and the cement space in Sintron did not significantly influence the marginal discrepancy. Conclusion: It has been concluded that the material kinds and cement space influence the restoration marginal discrepancy constructed by digital workflow.

Published: December 2020

Objective: The aim of this study was to compare the bond strength of High-Translucency zirconia (HT) and lithium disilicate dental ceramics, under different surface treatments. Material And Methods: For this, ceramics were divided into groups: Control Group (C) (n = 5), lithium disilicate sheets, conditioned with 10% hydrofluoric acid, followed by application of 37% phosphoric acid, silane and universal adhesive application; Group HTAI (n = 5), HT zirconia sheets were blasted with silica oxide, followed by the application of universal adhesive; Group HTPAI (n = 5), HT zirconia sheets were blasted with silica oxide, followed by the application of non-thermal plasma and universal adhesive and the HTP Group (n = 5), HT zirconia received only the application of non-thermal argon plasma. Subsequently, the specimens of each group were subjected to a cementation process with resin cement, obtaining cylinders. After 24 h of storage, in distilled water, at 37°C, the specimens were subjected to a mechanical micro-shear test. The data obtained were submitted to ANOVA One-way followed by the Tukey test (5%). Results: The HTP Group was excluded from the statistical analysis, as adhesions failed within the storage period. In addition, it was not possible to verify a statistical difference between the control group C and the experimental groups HTAI and HTPAI. Conclusion: The results showed that the applicability of high translucency zirconia can potentially be compared to the lithium disilicate bond strength, when submitted to the same surface treatments, except for the plasma application, which alone was not effective.

An analysis of triage process in a public hospital in Brazil: an approach basing in nurses work
Authors: Funchal João Paulo , Billa Cleo Zanella , Adamatti Diana Francisca
Published: December 2020

In this paper, the main idea is presented how the nurses do the triage process in a public hospital, since, although there is a set of rules for de ning each patient’s classification, in practice it is a very subjective activity. The present study was performed at the Dr. Miguel Riet Corrêa Junior University Hospital, in Rio Grande city, in south Brazil. The data were collected from patients between the year 2012 and 2017 in emergency department during the triage process. The Brazilian protocol to triage process in emergency department was defined as a law just in 2009 by Healthy Ministry. However, the university hospital just putted into operation its system in 2012. As the triage process is very subjective, the classification is dependent of each nurse and the time of the work, because when there are many people in the emergency department, the classification differs.
Saberes sobre a malária: um estudo qualitativo baseado no Distrito do Lago, Província de Niassa (Moçambique – África)
Authors: Lima Agostinho Viana , Mitano Fernando
Published: December 2020

Procurou-se compreender o modo como a população do Distrito do Lago (Província de Niassa, Moçambique) percebe, previne e trata a malária. Trata-se de um estudo de cunho qualitativo, centrado na abordagem de modelos explicativos da doença, que contou com a participação de membros de agregados familiares, profissionais de saúde e médicos tradicionais. A coleta de dados aconteceu por meio de entrevistas, orientadas por um roteiro semiestruturado, realizadas nos meses de Setembro e Novembro de 2019 em 8 povoados do Distrito do Lago. Os resultados revelaram um entendimento de que a malária é uma doença causada pela picada de mosquito, perigosa e que mata quando não evitada (pelo uso da rede mosquiteira e a limpeza do pátio) e tratada através do Coartem® (arteméter + lumefantrina). Não obstante, a adesão às medidas convencionais prevenção e tratamento é determinada por factores socioeconómicos e estruturais, o que faz com que a população recorra a outras alternativas de prevenção e de tratamento ou de obtenção do Coartem®. Com isso, pode-se dizer que a noção, a prevenção e o tratamento da malária pela maioria dos participantes assentam-se na perspectiva biomédica, ao passo que o modelo popular de prevenção e tratamento configura-se como alternativa ou complemento, sobretudo para as pessoas mais necessitadas.

Basic Model of Work-life Balance for Married Women Working in Public Sector in Penang, Malaysia
Authors: Hassan Kalthum
Published: December 2020

This paper is to discuss a basic model of work-life balance for married women working in public sector. The model is formulated based surveys received from seventy-six (76) respondents working in various public sectors in Komplek Tun Abdul Razak (KOMTAR) Penang. The study discovered that basically there are two main factors contribute to work-life balance, family related factors and job-related factors. In addition, to achieve work-life balance and to ensure productive and efficient working women, there should be incentives and services provided by the employers and government/non-government agencies to ease the burden of working women both in managing their families and their work. The incentives and services suggested by the respondents are suitable and flexible leave policies, dependent care centres, flexible working hours and work-family activities and support system and also counselling service or employee assistance programme. Since the model is formulated based on a study carried-out only on a small number of respondents, further studies should be carried-out to confirm the model or to up-grade the model. However, the model can be a basic model for more detail and comprehensive model of work-life balance for working women in Malaysia in future.

Published: December 2020

In general the health care system and hospital takes a major role in the service sector. The clinical treatment successfully increases in the year for the treatment of both the medical and the technical innovations. A sample theoretical challenge exists in the patient flow analysis for real data. An existing method target on the audience and less concentration on the secondary statistical analysis, where the data obtain from the hospital not suitable for the analysis. So this limitation can overcome using the Exploratory Data Analysis (EDA), which helps in analysis of the patients flow in large hospital. The proposed frame work uses a machine learning method for the data classification processes. The feature extraction processes for the patient data applied for the larger hospital dataset and the individual hospital data. Some similar features are allowed to train over the Recurrent Neural Network (RNN) classifier for data modeling using the large hospital dataset. The output of the classifier has the specific details about the patients taken for the EDA method. The linear regression algorithm be the one kind of statistical tool for predicting the relationship between the variables. The proposed frame work is implemented using Mat lab R2014a software and the results were simulated. The relationship between the patient details and hospital information shows the status of the hospital as healthy and un healthy status.

Optimizing the power is one of the basic need in growing development of electronic and electrical fields. With development of various fields leads to the increase in the demand of power directly or indirectly. The common factors helps in reducing the usage of power consumptions are the time and seasonality factors which is analyzed based on data over a period. The other factors which may be taken in consideration are the number people in a region and their characteristics like gender and age group. We can improvise the AI model using the above external factors. Once the model predict it update the expected amount of electricity required in transformer and send mobile notification to the authorized person and the person can track the energy usage in mobile for analysis.

Published: December 2020

In the present paper, we consider the nonlinear periodic systems involving variable exponent driven by p(t)-Laplacian with a locally Lipschitz nonlinearity. Our arguments combine the variational principle for locally Lipschitz functions with the properties of the generalized Lebesgue-Sobolev space. Applying the non-smooth critical point theory, we establish some new existence results.

Audio and video materials keep users engaged on a website longer than any other content type and this is the kind of content most web users look for, and user statistics confirm this also on Europeana.eu. Hence the aim of the project Europeana Media was to improve the user experience with audiovisual material on the Europeana portal and deliver functionalities to better access and incorporate AV content from Europeana.eu into the working environments of researchers, educators and citizens by developing an Enhanced Unified Playout Service. This unified player is based on theInternational Image Interoperability Framework (IIIF), which provides a standardised method of describing and delivering images, video and audio over the web.

Authors: Seidlmayer Eva , Müller Rabea , Förstner Konrad U.
Published: December 2020

In the past decades, libraries have developed into sophisticated information centres. This evolution requires a new set of computational expertises and competencies but also a change in the general attitude toward continuous learning. “Library Carpentry”, as a lesson programme of the “The Carpentries” community offers an elaborate and evidence-based collection of approaches for efficient teaching of the required computational skills and concepts. This article introduces Library Carpentry and presents how it is applied at ZB MED-Information Centre for Life Sciences as a foundation for teaching digital literacy.

Smart automated heart health monitoring using photoplethysmography signal classification
Authors: Raj Remya , Selvakumar Jayakumar , Maik Vivek
Published: December 2020

This paper proposes a smart, automated heart health-monitoring (SAHM) device using a single photoplethysmography (PPG) sensor that can monitor cardiac health. The SAHM uses an Orthogonal Matching Pursuit (OMP)-based classifier along with low-rank motion artifact removal as a pre-processing stage. Major contributions of the proposed SAHM device over existing state-of-the-art technologies include these factors: (i) the detection algorithm works with robust features extracted from a single PPG sensor; (ii) the motion compensation algorithm for the PPG signal can make the device wearable; and (iii) the real-time analysis of PPG input and sharing through the Internet. The proposed low-cost, compact and user-friendly PPG device can also be prototyped easily. The SAHM system was tested on three different datasets, and detailed performance analysis was carried out to show and prove the efficiency of the proposed algorithm.

Objectives

Newborn screening (NBS) for β-thalassemia is based on measuring the expression of the hemoglobin A (HbA) fraction. An absence or very low level of HbA at birth may indicate β-thalassemia. The difficulty is that the HbA fraction at birth is correlated with gestational age (GA) and highly variable between individuals. We used HbA expressed in multiples of the normal (MoM) to evaluate relevant thresholds for NBS of β-thalassemia.

Methods

The chosen threshold (HbA≤0.25 MoM) was prospectively applied for 32 months in our regional NBS program for sickle cell disease, for all tests performed, to identify patients at risk of β-thalassemia. Reliability of this threshold was evaluated at the end of the study.

Results

In all, 343,036 newborns were tested, and 84 suspected cases of β-thalassemia were detected by applying the threshold of HbA≤0.25 MoM. Among the n=64 cases with confirmatory tests, 14 were confirmed using molecular analysis as β-thalassemia diseases, 37 were confirmed as β-thalassemia trait and 13 were false-positive. Determination of the optimum threshold for β-thalassemia screening showed that HbA≤0.16 MoM had a sensitivity of 100% and a specificity of 95.3%, whatever the GA.

Conclusions

NBS for β-thalassemia diseases is effective, regardless of the birth term, using the single robust threshold of HbA≤0.16 MoM. A higher threshold would also allow screening for carriers, which could be interesting when β-thalassemia constitutes a public health problem.

Objectives

The qualitative results of SARS-CoV-2 specific real-time reverse transcription (RT) PCR are used for initial diagnosis and follow-up of Covid-19 patients and asymptomatic virus carriers. However, clinical decision-making and health management policies often are based additionally on cycle threshold (Ct) values (i.e., quantitative results) to guide patient care, segregation and discharge management of individuals testing positive. Therefore, an analysis of inter-protocol variability is needed to assess the comparability of the quantitative results.

Methods

Ct values reported in a SARS-CoV-2 virus genome detection external quality assessment challenge were analyzed. Three positive and two negative samples were distributed to participating test laboratories. Qualitative results (positive/negative) and quantitative results (Ct values) were assessed.

Results

A total of 66 laboratories participated, contributing results from 101 distinct test systems and reporting Ct values for a total of 92 different protocols. In all three positive samples, the means of the Ct values for the E-, N-, S-, RdRp-, and ORF1ab-genes varied by less than two cycles. However, 7.7% of reported results deviated by more than ±4.0 (maximum 18.0) cycles from the respective individual means. These larger deviations appear to be systematic errors.

Conclusions

In an attempt to use PCR diagnostics beyond the identification of infected individuals, laboratories are frequently requested to report Ct values along with a qualitative result. This study highlights the limitations of interpreting Ct values from the various SARS-CoV genome detection protocols and suggests that standardization is necessary in the reporting of Ct values with respect to the target gene.
