Background
The presence of COVID-19 has led to the disruption of health systems globally, including essential reproductive, maternal, newborn and child health (RMNCH) services. This study aimed to assess the challenges faced by women who used RMNCH services in Nigeria’s epicentre, their satisfaction with care received during the COVID-19 pandemic and the factors associated with their satisfaction.

Methods
This cross-sectional survey was conducted in Lagos, southwest Nigeria among 1,241 women of reproductive age who had just received RMNCH services at one of twenty-two health facilities across the primary, secondary and tertiary tiers of health care. The respondents were selected via multi-stage sampling and face to face exit interviews were conducted by trained interviewers. Client satisfaction was assessed across four sub-scales: health care delivery, health facility, interpersonal aspects of care and access to services. Bivariate and multivariate analyses were used to assess the relationship between personal characteristics and client satisfaction.

Results
About 43.51% of respondents had at least one challenge in accessing RMNCH services since the COVID-19 outbreak. Close to a third (31.91%) could not access service because they could not leave their houses during the lockdown and 18.13% could not access service because there was no transportation. The mean clients’ satisfaction score among the respondents was 43.25 (SD: 6.28) out of a possible score of 57. Satisfaction scores for the interpersonal aspects of care were statistically significantly lower in the PHCs and general hospitals compared to teaching hospitals. Being over 30 years of age was significantly associated with an increased clients’ satisfaction score (ß = 1.80, 95%CI: 1.10–2.50).

Conclusion
The COVID-19 lockdown posed challenges to accessing RMNCH services for a significant proportion of women surveyed. Although overall satisfaction with care was fairly high, there is a need to provide tailored COVID-19 sensitive inter-personal care to clients at all levels of care.

BackgroundThe ageing population brings about the appearance of age-related health disorders, such as osteoporosis or osteopenia. These disorders are associated with fragility fractures. The impact is greater among postmenopausal women due to an acceleration of bone mineral density (BMD) loss.ObjectiveTo estimate the effectiveness of Pilates or Yoga on BMD in adult women.MethodsFive electronics databases were searched up to April 2021. Randomized controlled trials (RCTs), non-RCTs and pre-post studies were included. The main outcome was BMD. Risk of bias was evaluated using the Cochrane risk of bias tool. A random effects model was used to pool data from primary studies. Subgroup analyses based on the type of exercise were conducted.ResultsEleven studies including 591 participants aged between 45 and 78 years were included. The mean length of the interventions ranged from 12 to 32 weeks, and two studies were performed for a period of at least one year. The pooled effect size for the effect of the intervention (Pilates/Yoga) vs the control group was 0.07 (95% Confidence interval [CI]: -0.05 to 0.19; I2= 0.0%), and 0.10 (95% CI: 0.01 to 0.18; I2= 18.4%) for the secondary analysis of the pre-post intervention.ConclusionsDespite of the non-significant results, the BMD maintenance in the postmenopausal population, when BMD detrimental is expected, could be understood as a positive result added to the beneficial impact of Pilates-Yoga in multiple fracture risk factors, including but not limited to, strength and balance.
“Africa does not Fit in Europe”
Authors: Cervi Laura , Tejedor Santiago 
Published: May 2021

The politicization of immigration has moved the debate about immigration at the center of the run-up of elections, creating the breeding ground for the electoral breakthrough and success of right-wing populist parties.
This article aims at disclosing the narrative of immigration and its politicization in VOX’s discourse, comparing it to the Italian Lega party.
Clause-based semantic text analysis reveals that both parties share the classic characteristics of nativist populism: the representation of a virtuous and hardworking people, threatened by the invasion by some “others”, immigrants, who intrude the sovereign, antispace of natives to exploit and commit crimes. In both cases, the concept of space is manipulated, representing countries as limited spaces, allowing to depict immigrants as a threat to legitimize negative political responses.
The study also identifies a novelty: the construction of the rescue NGOs as the new antagonist actor.
Professionnalisation et politisation des commentaires numériques sur la marque Orange en Afrique de l'Ouest
Authors: Seck-Sarr Sokhna Fatou 
Published: May 2021

Cet article explore la professionnalisation et la politisation des commentaires numériques sur la marque de l’opérateur mobile Orange en Afrique subsaharienne. Il souligne d’abord la surreprésentation de commentaires négatifs publiés sur Facebook et Twitter ainsi que la diversité des actions de boycott initiées par les internautes « clients » : orangesatch (2013), Boycott-orange-Niger (2015) Stop aux anarques d’orange Mali (2015) Afrique boycott orange (2016) ou encore Talatay-orange (2018). Il détaille ensuite la nature des commentaires numériques, aux soubassements idéologiques, politiques, voire géopolitiques, ainsi que le détournement des messages publicitaires de la marque (Cultural Jamming) par les contestataires disposant a priori de compétences techniques et sociales. L’étude expose les tactiques privilégiées par la marque Orange notamment la mise en place de « Team digitale » pour animer ses pages Facebook et comptes officiels Twitter ainsi que le recours à des blogueurs/influenceurs pour renforcer son autorité réputationnelle. Enfin, le caractère promotionnel ou divertissant des réponses apportées par les community managers de la marque, dans une situation de communication sensible pouvant déboucher sur une crise, interroge les compétences reliées à l’autorité énonciative de la marque.
Promouvoir « la parité » en entreprise : un enjeu de communication source de dépolitisation de l'égalité
Authors: Bruneel Emmanuelle 
Published: May 2021

Cet article s’intéresse à une campagne de communication hybride qui fait la promotion du « volet parité » la politique « diversité » de l’entreprise Accenture intitulée Equals. Son objectif, à la fois institutionnel et promotionnel, est d’attirer les talents en montrant l’entreprise énonciatrice comme un espace de travail où il fait bon travailler. Diffusés dans l’espace public comme en interne de l’organisation, les affiches et leurs messages sont les objets analysés ici. Notre analyse critique du discours de campagne montre la manière dont il reproduit une bicatégorisation genrée normative en soulignant que l’engagement égalitariste déclaré est conditionné à une égalité préalable. Il souligne que les efforts consentis par l’entreprise en vue d’un traitement plus égalitaire sont arrimés à la démonstration des compétences et des performances professionnelles des femmes. Cette posture discursive renvoie implicitement au fait que celles-ci sont elles-mêmes responsables des phénomènes inégalitaires qu’elles subissent dans le monde du travail. Les inégalités sources de discriminations ne sont ici ni montrées ni prises en compte. Ce discours de campagne qui présente l’implication de l’entreprise pour davantage d’égalité constitue dès lors, paradoxalement, un discours à caractère euphémique et aux effets dépolitisants.
Evaluer la communication interne. Une approche critique.
Authors: Heller Thomas 
Published: May 2021

Ce texte porte sur l’évaluation de la communication interne. Partant de l’impératif d’évaluation professé par certains professionnels, et en nous appuyant sur une description de l’étendue du domaine de l’évaluation, nous mettons en évidence deux limites à l’évaluation de la communication interne : une limite de type gestionnaire, centrée sur les rapports de causalité entre communication et efficacité, et une limite de type idéologico-politique, centrée sur le rôle affiché de la communication interne dans la littérature professionnelle. Nous concluons en soulignant qu’une approche politique de l’évaluation de la communication interne mériterait de prendre en considération d’autres pratiques que celles qui concernent l’action des professionnels de la communication, et notamment l’évaluation des comportements relationnels, et celle de la dynamique interactionnelle dans les organisations grâce aux technologies numériques.
SCM Professionals’ Competences in Brazil
Authors: Reis Manoel A. S. , Minerbo Claudio , Miguel Priscila L. S. 
Published: May 2021

Goal: This paper aims to examine the competences required from supply chain management professionals in Brazil.
Design / Methodology / Approach: A survey with 239 professionals explored 44 different competences they deemed important.
Results: Competences can be grouped in eight categories, some of which updated to reflect the changes in the SCM practice. It reinforces the importance for general behavioral, technical, analytical and business competences, suggested in previous research, and provides a more granular view and emphasizes differences of technical expertise depending on the scope of the manager's function. Technology, information systems and quantitative skills are different competences required to support changes in e-commerce and digital transformations.
Limitations of the investigation: Differences among industry sectors or functions should be investigated in more detail due to respondent´s heterogeneity
Practical implications: Our study can serve as a guide when searching new talents and training SCM professionals, as it emphasizes competences common to all SCM functions and specific depending on their scope.
Originality / Value: Firms operating in service sectors generally demand higher levels of business awareness competences than the ones in manufacturing sectors. This reflects the service-dominance logic, where service is the fundamental basis of exchange and firms need to be more customer oriented.
Pseudohyperkalaemia in essential thrombocytosis: an important clinical reminder
Authors: Mizzi Jean Marc , Rizzo Christopher , Fava Stephen 
Published: May 2021

Summary
An 82-year-old female was admitted to a general hospital due to progressive bilateral lower limb weakness. A T8–T9 extramedullary meningioma was diagnosed by MRI, and the patient was referred for excision of the tumour. During the patient’s admission, she was noted to have persistent hyperkalaemia which was refractory to treatment. Following a review by an endocrinology team, a diagnosis of pseudohyperkalaemia secondary to thrombocytosis was made. This case demonstrates the importance of promptly identifying patients who are susceptible to pseudohyperkalaemia, in order to prevent its potentially serious consequences.

Learning points

Pseudohyperkalaemia should be considered in patients with unexplained or asymptomatic hyperkalaemia. It should also be considered in those patients who are resistant to the classical treatment of hyperkalaemia.

A diagnosis of pseudohyperkalaemia is considered when there is a difference of >0.4 mmol/L of potassium between serum and plasma potassium in the absence of symptoms and ECG changes.

In patients who are presenting with consistently elevated serum potassium levels, it may be beneficial to take venous blood gas and/ or plasma potassium levels to rule out pseudohyperkalaemia.

Pseudohyperkalaemia may subject patients to iatrogenic hypokalaemia which can be potentially fatal.

Pseudohyperkalaemia can occur secondary to thrombocytosis, red cell haemolysis due to improper blood letting techniques, leukaemia and lymphoma.
Overexpression of miR-7977 in CD4+ T cells is associated with multiplex autoimmunity in patients with Addison’s disease

Published: May 2021

Objective
Autoimmune Addison’s disease (AD) results from a combination of the genetic predisposition, unclear environmental triggers and ensuing immune dysfunction. MicroRNA molecules (miRNAs) are involved in post-transcriptional regulation of numerous target genes, hence may affect the immune function and promote autoimmunity. A deregulated miRNAs profile was reported in several autoimmune conditions. Our study was aimed at a global analysis of miRNA expression in CD4+ T cells from patients with AD.

Methods
CD4+ T cells were separated from peripheral blood, total RNA enriched in miRNAs extracted, and miRNA expression determined by small RNA sequencing. Global miRNA was investigated in 11 AD subjects and 9 age-matched healthy controls, with subsequent validation of the differentially expressed miRNAs by RT-qPCR in 29 patients and 28 controls.

Results
The analysis revealed upregulation of 9 miRNAs and downregulation of miR-509-3p in CD4+ T cells from patients with AD (cut-off fold change (FC) >2, Benjamini–Hochberg P  < 0.05). RT-qPCR validation confirmed overexpression of miR-7977 (P < 0.0001, FC = 2.7), miR-374a-5p and miR-1260b (P < 0.05, FC = 1.3 and 1.2, respectively). miR-7977 was upregulated in patients with coexisting autoimmune conditions vs those with isolated AD (P = 0.005, mean FC = 2.2). Moreover, miR-7977 abundance appeared correlated with the number of autoimmune comorbidities (P <0.0001, r = 0.736) and serum autoantibodies against thyroid peroxidase (P < 0.001, r = 0.588).

Conclusions
Our study demonstrates upregulated expression of miR-7977 in CD4+ T cells from patients with AD, especially with its polyendocrine form. Further analyses are warranted to replicate our results, establish the marker utility of miR-7977, and elucidate its functional role in autoimmunity.
Patologizados, fatigados y perdidos

El artículo analiza la emergencia de la depresión como la enfermedad mental más frecuente en la modernidad tardía. Desde el existencialismo sociológico de Peters (2017) concibe la depresión como un particular modo de inseguridad ontológica. Sostiene que el incremento de los diagnósticos es comprensible a partir tres amplias claves interpretativas vinculadas a transformaciones en las sociedades tardo-modernas. La primera alude a una creciente patologización de la angustia asociada a la emergencia de modos de conceptualizar el sufrimiento psíquico. La segunda refiere a la profundización de los imperativos de autorrealización que provocan patologías del agotamiento del yo. La tercera destaca la expansión de una multiplicidad de guías de referencia que se manifiesta en una pérdida de sentido de la existencia. La depresión contemporánea representa, simultáneamente, una patología retórica, de la acción y del sentido correlativa con figuraciones del sujeto patologizado, fatigado y perdido.

Ferronickel slag is a by-product of the nickel smelting process. Recycling of ferronickel slag is required since it contains valuable elements besides its potency to pollute the environment. In order to take advantage of the valuable materials and reducing the potential hazard, beneficiation of ferronickel slag is essential. Alkali fusion of ferronickel slag using Na2CO3 in the roasting process was carried out. This study aims to determine the decomposition of the mixture of ferronickel slag-Na2CO3 in the roasting process. Roasting temperature and time were 800–1,000 °C and 60‒240 minutes, respectively. Characterizations of the ferronickel slag were conducted by XRF, ICP-OES, XRD and SEM-EDS. Meanwhile, roasted products were characterized using ICP-OES, XRD and SEM-EDS. Characterization of the ferronickel slag indicates that Mg and Si are the main elements followed by Fe, Al and Cr. Moreover, olivine is detected as the main phase. The roasting process caused percent weight loss of the roasted products, which indicates decomposition occurred and affected the elements content, phases and morphology. The roasting process at about 900 °C for 60 minutes is a preferable decomposition base on the process conditions applied and the change of elements content. Aluminum (Al) and chromium (Cr) content in the roasted products upgraded significantly compared to iron (Fe) and magnesium (Mg) content. Olivine phase transforms to some phases, which were bounded with the sodium compound such as Na2MgSiO4, Na4SiO4 and Na2CrO4. The rough layer is observed on the surface of the roasted product as a result of the decomposition process. It indicates that liquid-solid mass transfer is initiated from the surface

This research aims to simulate structural steel 400 (SS400) material as an alternative material for the electric bus's chassis structure. The kind of the material is low carbon steel. The SS400 material is produced from one of the largest steel mills in Indonesia, considered a local material. The local material used to increase the total domestic content in electric cars in Indonesia could be improved. Generally, the reverse engineering method of the R260 ladder frame type chassis is used to increase the local content in electric vehicles. However, this research used a ladder frame of type SS400 from local material to fulfill the local content of vehicle (EV)-bus chassis with the reverse engineering method. After the model was successfully created using the finite element software, statics analysis was carried out using the von Mises stress and the simulation results' deflection. The meshing process of the chassis structure is carried out in such a way as to assume global contact. Loading was evenly carried out over the two main beam ladder frames totaling 14,200 kg. The elasticity modulus and tensile strength values used for the material are 190 GPa and 480 MPa. Furthermore, the support was placed in the mounting position of the front and rear wheel leaf springs at a front, rear overhang, and wheelbase distance of 2,380 mm, 3,290 mm, and 6,000 mm. The resulting approach was carried out using a beam model with a two-overhang beam model. The simulation results showed that type SS400 from the local material obtained a maximum von Mises stress value of 75.8 MPa, deflection of 2.568 mm, and the lowest safety factor of 3.2. Meanwhile, through theoretical calculations, the obtained stress occurred in 72.33 MPa and deflection of 2.594. There is no significant difference between simulation results and theoretical results

The study object: the chemical engineering system for production of benzene and optimization of the system operation modes based on modeling. An approach to the effective solution of problems of optimization of operating modes of real chemical engineering systems was proposed. Since such systems are usually multicriterial and characterized by the fuzziness of initial information, an approach to the development of their models and optimization of their operating modes in a fuzzy environment was proposed. The essence of this approach lies in the construction of mathematical models and optimization of system operation modes based on the system analysis methodology using available information of deterministic, statistical, and fuzzy nature. Statements of the problems of optimization by means of chemical engineering systems in a fuzzy environment have been obtained by modifying various principles of optimality for working in a fuzzy environment. Based on a modification of the principles of maximin and Pareto optimality, a heuristic algorithm for solving the formulated optimization problem was proposed based on the use of knowledge and experience of decision-makers. The proposed method of model construction and an optimization algorithm were implemented in practice when constructing models of benzene and rectification columns of a chemical engineering system of production of benzene when formulating and solving the problem of optimizing their operation modes in a fuzzy environment. Analysis and comparison of optimization results allow us to conclude about the effectiveness of the proposed fuzzy approach to solving optimization problems in a fuzzy environment. As a result of optimization of the benzene production process, the benzene yield increased by 1.45 thousand t or by 1.1 %, the raffinate output volume increased by 0.4 thousand t in conditions of upholding constraints on benzene quality. The proposed approach makes it possible to assess the degree of upholding of fuzzy constraints
