Le Brexit : liberté ou tragédie ?
Authors: Wright David
Published: January 2023

Le vote en faveur du Brexit lors du référendum de juin 2016 a libéré de nouvelles forces politiques et économiques puissantes au Royaume-Uni (RU) et dans l'Union européenne (UE). Pourquoi et comment cela s'est-il produit ? On n'a jamais dit la vérité sur l'UE au peuple britannique – ni sa raison d'être en tant qu'organisation politique internationale chargée de construire une paix durable sur le continent européen, ni les avantages d'une étroite coopération européenne dans un monde interconnecté et multipolaire fondé sur des traités juridiquement contraignants. L'euroscepticisme au RU, construit pendant quarante ans, n'a pas été contesté par des générations de responsables politiques et a été, sans relâche, alimenté par une presse britannique hostile et agressive. Il n'y a aucune preuve à ce stade que le RU ait prospéré hors de l'UE ; au contraire, politiquement et économiquement, il a régressé. Il est devenu moins fiable, économiquement instable et moins influent au niveau international. L'intégration européenne, cependant, a progressé de manière significative depuis que le RU a quitté l'UE, mais l'UE a aussi perdu certains importants atouts et qualités britanniques.

Réflexions sur la réglementation financière de l'UE post-Brexit
Authors: Campa José Manuel
Published: January 2023

Cet article propose un aperçu des efforts accomplis dans la sphère réglementaire et de supervision pendant la première phase post-Brexit et présente les défis à venir. Le Brexit a créé un nouvel environnement pour les institutions financières en Europe. Les banques, les régulateurs et les superviseurs ont travaillé sans relâche pour assurer une transition la plus équilibrée possible. Le Brexit a entraîné des changements structurels pour les établissements de crédit qui ont dû adapter leurs opérations en direction du marché de l'Union européenne (UE). Le Brexit a aussi mis à jour les dépendances de l'UE vis-à-vis du secteur financier britannique, notamment en matière de clearing de dérivés, qu'il faudra bien résoudre dans le futur. Pour l'avenir, l'UE et le Royaume Uni devront continuer à s'engager pour la préservation des marchés financiers ouverts et l'application des standards réglementaires internationaux dans le secteur financier. Ces principes devraient contribuer à construire un cadre de coopération capable d'éviter la fragilisation des standards financiers, le risque de fragmentation ou les dysfonctionnements des marchés financiers.

Au lendemain du Brexit
Authors: Boujnah Stéphane
Published: January 2023

Les effets du Brexit sur les marchés financiers sont encore incertains. Les transferts d'emploi vers l'UE sont progressifs, avec des effets très marqués à Paris, Dublin, Amsterdam et Francfort, même si Londres demeure encore la place financière la plus dense en Europe. Mais la sortie de la City du cadre réglementaire de l'UE a changé profondément les perspectives d'évolution de l'environnement concurrentiel. Les choses ont déjà changé en matière d'introductions en bourse. Pour amplifier cette dynamique, il faut désormais inscrire l'Union des marchés de capitaux dans une ambition politique d'autonomie stratégique, c'est-à-dire orienter nos projets vers la construction d'un modèle véritablement européen avec des centres financiers distribués mais intégrés et fortement interconnectés. Face au risque d'empilement de mesures technocratiques secondaires qui affaiblissent les acteurs financiers de l'UE, trois priorités doivent désormais prévaloir à la Commission, au Conseil et au Parlement européen : simplification, compétitivité et autonomie stratégique.

Rawls and the Economists: The (Im)possible Dialogue
Authors: Igersheim Herrade
Published: January 2023

Bien que relevant de la philosophie politique et morale, il est bien connu que Théorie de la justice a également eu un grand impact sur les économistes. À ce titre, Rawls a beaucoup insisté sur sa volonté de combiner économie et philosophie, en particulier via la théorie du choix rationnel, affirmant notamment que « la théorie de la justice est une partie, peut-être même la plus importante, de la théorie du choix rationnel » (Rawls [1971]). Après la publication de Théorie de la justice, certains aspects de celle-ci ont fait l’objet de critiques – souvent très véhémentes – de la part d’économistes tels que Arrow [1973], Musgrave [1974], Harsanyi [1975] et plus tard Sen [1980]. Les réponses immédiates de Rawls ([1974a], [1974b] en particulier) indiquent qu’il a tout d’abord souhaité maintenir un dialogue avec les économistes, mais les évolutions ultérieures de ses travaux ([1993], [2001]) ont clairement démontré qu’il s’était éloigné de la théorie économique, revenant à la philosophie afin de surmonter les incohérences internes de sa théorie. Dans cet article, en me concentrant principalement sur les échanges épistolaires entre Rawls et les économistes avant et après la publication de Théorie de la justice, je tente de mettre en lumière d’autres éléments (complémentaires) qui peuvent expliquer le retrait de Rawls vis-à-vis de l’économie, et son désenchantement progressif quant à la possibilité d’un dialogue sur un pied d’égalité entre économistes et philosophes.

Identification of Avascular Necrosis or Osteoporosis Using Deep Belief Convolutional Neural Networks
Authors: B. Sankaragomathi , S. Senthil Kumar
Published: January 2023

Musculoskeletal impairment can be caused by Avascular Necrosis(AN). Younger people are more likely to develop it, thus early intervention and fast diagnosis are essential. The femoral bones are typically affected by this condition, which results in fractures that change the geometry of the bones. It is difficult to retrieve the AN-affected bone pictures because of the many places where the fractures are located. In this work, a useful method for retrieving AN pictures using deep belief CNN feature representation is proposed. Preprocessing is first applied to the raw dataset. In this stage, the median filter (MF) is used to reduce image noise and downsize the image. Using a deep belief convolutional neural network, features are represented (DB-CNN). The representations of the image feature data have now been converted to binary codes. Then, using the modified-hamming distance, the similarity measurement is calculated. The images are then retrieved with a focus on the similarity values. The test results demonstrated that the proposed approach is superior to the other methods now in use.

Published: January 2023

This research was conducted to determine the corrosion rate by varying the concentration of the solution against hydrochloric acid and sulfuric acid. The method used is open circuit potential (OCP) and Tafel plot. Based on the research conducted, Hastelloy C-276 was more prone to get oxidized in sulfuric acid rather than hydrochloric acid. It can be seen from the OCP value of sulfuric acid was much more negative than that of hydrochloric acid as of-1.5 V for 0.5 M sulfuric acid and-0.2 V for hydrochloric acid. The corrosion rate of Hastelloy C-276 in sulfuric acid was also higher compared to same alloy in hydrochloric acid. At the most concentrated solution, 0.5 M, the corrosion rate of sulfuric acid reached 0.39 mmpy and as for corrosion cate in hydrochloric acid, only at 0.16 mmpy. It is thought that there was a difference of passive film composition for both solutions. Keywords: Hastelloy C-276, Corrosion, Hydrochloric acid, Sulfuric acid.

Authors: Siregar Shinta Marito , Humaidi Syahrul , Bukit Nurdin , Frida Erna
Published: January 2023

XRF characterization results showed that coal boiler ash contained SiO2 = 29.3%; Al2O3= 14%; Fe2O3= 30.9%; CaO= 18.3% and palm shell boiler ash containing SiO2 = 48.9%; Fe2O3= 3.42%; CaO= 13.8%. The FTIR test results show that the OH stretching vibration of the SiOH group absorbs in the regions 3676, 3597, 3462, and 3315 cm-1 at the peak of the coal boiler ash spectrum and 3614, 3502, 3365, and 3323 cm-1 at the peak of the palm shell boiler ash spectrum. From the ECC mortar FTIR test results, it can be seen that the functional group changes with the OH stretching vibration of the SiOH group absorbing in the 3387 cm-1 area. The results of the ECC mortar compressive strength test at 28 days increased with the addition of coal boiler ash up to 15% and palm shell boiler ash 10%, so the compressive strength was 59.30 MPa.
Synthesis of PAN Fibre-Supported Visible Light-Activated Carbon-Doped TiO2 for Toluene Degradation of Interior Wall Paints
Authors: Tian Qi Ping , Xu Meng , Tian Zhen Yu , Yuan Rong Hui , Liu Qiu Xiang
Published: January 2023

Polyacrylonitrile (PAN) fibre-supported carbon (C)-doped TiO2 (PCT) was fabricated by electrospinning C-doped TiO2/PAN/N,N-dimethylformamide mixtures. C doping was found to be a promising method for enabling visible photoactivation of TiO2 using graphite and PAN fibres as carriers. The fibrous PAN not only facilitated visible light-activated harvesting of TiO2 but also enabled the incorporation of C into the TiO2 lattice during the preparation process. Such composite fibres endowed TiO2 with high photocatalytic activity, and they were utilised to degrade toluene from interior wall paints with excitation at 440 nm. Given the maximum removal efficiency of 96.8% within 1 h, the developed photocatalysts can be considered to have paint hazard remediation properties.
Increased Reflection Loss of SrFe(11.9-x) In0.1Snx/2Znx/2O19 (x = 0.0; 0.10; 0.35 and 0.50): A Microwave Absorber Induced by Reduced Coercivity

Published: January 2023

In this study, an increase in the reflection loss (RL) value for SrFe(11.9-x)In0.1Snx/2Znx/2O19 samples (x = 0; 0.10; 0.35 and 0.50) is reported. The X-ray diffraction (XRD) pattern of all samples confirmed that the SrFe(11.9-x)In0.1Snx/2Znx/2O19 samples (x = 0, 0.10, 0.35, and 0.50) posses polycrystalline with single phase. We have demonstrated that co-substitution of Zn2+ and Sn4+ ions with a fraction of x = 0.10 reduced the coercivity of the pure nano strontium hexaferrite (SHF) from 346.80 kA/m to 50.34 kA/m. The substitution of Fe3+ ion by Sn2+ and Zn4+ affect the coercivity decreased significantly. Meanwhile, the saturation magnetization and remanence slightly decreases. Hence, the decreasing of coercivity cause the reflection loss (RL) increase from -16.43 dB to -25.62 dB. We believed the RL value can be increased efficiently by reducing the coercivity of the sample obtained by co-substitution of Zn2+ and Sn4+ ions to Fe3+ in the main phase of SrFe11.9In0.1O19.

The effect of alkali fluoride on the photoluminescence properties of Tb3+ doped on the phosphate glass was discovered. However, the composition of the glass samples were 20Li2O–10AlF3–69P2O5–1Tb2O3 (LAPTb) and 20Li2O–10AlF3–10NaF–59P2O5–1Tb2O3 (LANPTb). To study optical properties were examined through their absorption and luminescence spectra. Luminescence spectra were investigated by photoluminescence. Characteristic luminescence bands corresponding to electronic transitions of terbium ions (Tb3+) were detected under two direct excitations of Tb3+ ions. Upon 377 nm excitation, the glass samples were obtained transition terbium 5D4 → 7F5 at 544 nm showed a green laser. The decay time Tb3+ for the 5D4 level has been confirmed and the result was 2.865 ms and 2.982 ms corresponding to LAPTb was LANPTb, respectively. The green laser application has been investigated by a CIE-color-coordinates diagram with a color purity is ~73%.

Published: January 2023

CoO nanocrystal is well-known photocatalyst for overall water splitting. However it suffers from a very short lifetime of only 1 h. The poor stability is derived from carrier recombination-induced thermal oxidation. This research will provide information about synthesis of CoO/ZnO nanocrystalline that can potentially enhance photocatalysts. CoO has been synthesized first under hydrothermal method, followed by calcination process. Thereafter, CoO has been used to produce CoO/ZnO under precipitation method. The samples were characterized using XRD (X-Ray Diffraction), FTIR (Fourier Transform Infrared Spectroscopy), and UV-VIS (UV–Visible Spectroscopy) to analyze their composition, chemical functional group, optical absorption, and band gap. The XRD spectrum showed that CoO/ZnO had cubic spinel and hexagonal phase structure with crystallite size of 69.0, 46.4, 32.8, and 32,4 nm. The bands in obtained FTIR spectrum at 586.36, 671.23, and 410-429 cm−1 were correlated with vibrations of the Co3+ in octahedral hole, the Co2+ in tetrahedral hole, and Zn-O, respectively. The band gap energy of CoO, CoO/ZnO with variation of 1:1 and 1:3 were 4.39, 4.14, and 3.65 eV, respectively. The photocatalytic activities of CoO/ZnO were confirmed by methylene blue dyes photodegradation of 663 nm under UV light irradiation in aqueous solution. The 22.4% methylene blue can be removed within 3 h. Overall, these findings reveal the potential of CoO/ZnO for practical application.
Involvement of Parathyroid Gland in COVID-19
Authors: Niranjan R.
Published: January 2023

Introduction: Parathyroid glands are yellow brown, small and soft. Typically four parathyroids are present in posterior surface of thyroid. Parathyroid’s numeral, size and site is inconstant. Corona virus disease-19(COVID-19) is a major problem all over world and aim of this study is to discuss possible involvement of parathyroid in COVID-19.Materials and methods: The previous studies were used for this review study.Results and discussions: The COVID-19 mainly causes pulmonary injury and respiratory failure. Virus was chiefly detected in respiratory pathway, gastrointestinal tract, sweat gland, pituitary, pancreas, adrenal, renal, parathyroid, liver and cerebrum. Nearly 65% of COVID-19 patients had hypocalcaemia. Advanced age and hypocalcaemia were bad prognostic factors for COVID-19 patients. Hypocalcaemia might be due to vitamin-D deficit, decreased bowel absorption of calcium, diminished secretion or response to parathyroid hormone (PTH). The PTH rises serum calcium by discharge calcium by osteoclastic activity, calcium reabsortion in nephron. Vitamin-D encourage reabsorption of dietary calcium. Thus inadequate Vitamin-D excites parathyrood to discharge more PTH. Normal and abnormal parathyroids are identified by their size, form, consistency and histological judgments. There was association between size of parathyroid and PTH level. Glands of black populations were longer than white groups. Larger parathyroid secrets more PTH and might has greater number of chief cells. Microscopically quantity of fatty tissues and oxyphil cells rise in elders. Both transitional and oxyphil cells secrets PTH to extensive parathyroid stimulation.Conclusion: Size of all parathyroids, patient’s age, oxyphil cells amount, ethnicity, amount of PTH and Vitamin-D determines the serum calcium level in COVID-19.

Published: January 2023

The inferior mesenteric vein is one of the tributaries of the portal vein which receives blood from the large intestine, sigmoid colon and the rectum. It usually connects with the splenic vein before draining into the portal vein. It may however show variations such as joining the superior mesenteric vein directly or to the confluence of the superior mesenteric vein and splenic vein. Varices of the inferior mesenteric vein can be seen in the presence of portal hypertension due to various reasons and this can be isolated or in association with other portosystemic collaterals.
We report a case of a giant isolated inferior mesenteric vein with an anomalous insertion. The inferior mesenteric vein was seen to be connected to the superior mesenteric vein before draining into the portal vein. Further, on the distal end it was seen to be connected to the left renal vein, which in turn had dilated and enlarged. The left testicular vein was observed draining in to the inferior mesenteric vein but was not enlarged. The superior mesenteric vein, splenic vein and portal vein were not enlarged or varicosed even though the liver showed features of cirrhosis with no obvious signs of splenic enlargement.
This report contributes to enhance the knowledge on a rare anatomical connection between portal system and the systemic circulation and will be important to surgeons operating in this area.

Published: January 2023

Hallmarks of life-threatening, coronavirus-induced disease include dysregulated antiviral immunity and immunopathological tissue injury. Nevertheless, the sampling of symptomatic patients overlooks the initial inflammatory sequela culminating in severe coronavirus-induced disease, leaving a fundamental gap in our understanding of the early mechanisms regulating anticoronavirus immunity and preservation of tissue integrity. In this study, we delineate the innate regulators controlling pulmonary infection using a natural mouse coronavirus. Within hours of infection, the cellular landscape of the lung was transcriptionally remodeled altering host metabolism, protein synthesis, and macrophage maturation. Genetic perturbation revealed that these transcriptional programs were type I IFN dependent and critically controlled both host cell survival and viral spread. Unrestricted viral replication overshooting protective IFN responses culminated in increased IL-1β and alarmin production and triggered compensatory neutrophilia, interstitial inflammation, and vascular injury. Thus, type I IFNs critically regulate early viral burden, which serves as an innate checkpoint determining the trajectory of coronavirus dissemination and immunopathology.

Published: January 2023

Mitochondrial antiviral signaling protein (MAVS) is a key adaptor in cellular innate immunity. Ubiquitination plays an important role in regulating MAVS-mediated innate immune responses; however, the molecular mechanisms underlying ubiquitination of MAVS have not been fully elucidated. In this study, we first identified the mitochondria-resident E3 ligase duck membrane-associated RING-CH 8 (duMARCH8) in ducks as a negative regulator of duck MAVS (duMAVS). Overexpression of duMARCH8 impaired the duMAVS-mediated signaling pathway, whereas knockdown of duMARCH8 resulted in the opposite effects. The suppression was due to duMARCH8 interacting with duMAVS and degrading it in a proteasome-dependent manner. We further found that duMARCH8 interacted with the 176–619 regions of duMAVS. Moreover, duMARCH8 catalyzed the K29-linked polyubiquitination of duMAVS at Lys 398 to inhibit the MAVS-mediated signaling pathway. Collectively, our findings reveal a new strategy involving MARCH8 that targets the retinoic acid–inducible gene-I–like receptor signaling pathway to regulate innate immune responses in ducks.
Spatial-temporal study of cluster 5 picocyanobacteria and exopolymeric microgels in Lake Maggiore
Authors: Callieri Cristiana , Sabatino Raffaella , Di Cesare Andrea , Bertoni Roberto
Published: January 2023

In the oligotrophic Lake Maggiore, the majority of picocyanobacteria are phycoerythrin-bearing Synechococcus-type belonging to cluster 5 (Pcy-5). Their distribution was followed in a seven-year study along a depth gradient from the surface down to 350 m in relation to Transparent Exopolymer Particles (TEP), Total Organic Carbon (TOC), Chlorophyll-a (Chl-a) and water temperature. Pcy-5 abundances exhibit pronounced inter-annual variability, showing years of high numerical abundances as well as years with low numbers. In the upper 20 m, Pcy-5 peaks at around 10-15 m and then progressively decreases. Here, the Pcy-5 presence has been outlined for the first time in the deep layers of a deep lake, thus opening an interesting discussion on these organisms’ survival mechanisms in the absence of the light needed to perform photosynthesis. The relation of Pcy-5 with extracellular microgels was significant in autumn, when peaks of both variables were observed. In the other seasons, TEP was correlated with temperature and Chl-a, indicating the autochthonous origin of this fraction.

Authors: Bagheri Mehdi , Shayan Shahram , Jowkar Fariba
Published: January 2023

BACKGROUND:

Educational managers at universities of medical sciences are the suppliers of human resources to the healthcare system. Thus, attention to their professional empowerment can play a prominent role in improving the quality of medical science education.

MATERIALS AND METHODS:

The present study was implemented through the method of modeling and in the three stages of conceptual, modeling, and validation. The research environment was the medical science universities of Iran and the sampling method was purposive. The two qualitative approaches of literature review and semi-structured interview were used to develop the components of the model. The results were then integrated, the relationships between the components were investigated, and the model was eventually finalized. The resulting scores were analyzed using MicMac software.

RESULTS:

Twelve categories and 20 subcategories were identified in the first micro-study (desk research). Qualitative analysis of the interviews in the second stage led to the identification of 21 subcategories and seven categories. Components of the conceptual model were extracted from the results of the two first stages, both of which were aimed at the extraction of concepts relevant to dynamic empowerment of medical science educational managers, and the conceptual model for dynamic empowerment of medical science education managers was designed in the six categories of education, decision-making, organization, belief, dynamic capabilities, and environment after the interactions between the components were studied.

CONCLUSIONS:

Results of the present study revealed that dynamic empowerment of the managers is a multifaceted and multidimensional concept, and all of the factors incorporated in the conceptual model for dynamic empowerment of managers must receive special attention.

Authors: Keshmiri Fatemeh , Jambarsang Sara , Mehrparvar Amir Houshang
Published: January 2023

BACKGROUND:

The teacher must conduct educational responsibilities in the best way by observing the ethical principles to meet students' educational needs. The aim of the study was to investigate the main factors of professionalism among faculty members from the viewpoints of various stakeholders including learners, peers, and educational officials, as well as the components were assessed from the viewpoints of the stakeholders.

MATERIALS AND METHODS:

This was a descriptive analytical study conducted in two phases. In the first phase, a questionnaire was developed and validated to assess the professional behavior of faculty members. In the second phase, the evaluation of the teachers' professional behavior was done from the viewpoint of various stakeholders, including learners, middle and senior education managers and peers. The participants were faculty members from 10 schools enrolled in the study by census (n = 427). To extract the factors that constitute professional behavior in faculty members, exploratory factor analysis was used. Data were summarized using descriptive indices (mean, standard deviation, and percent). Exploratory factor analysis (EFA) was used to extract the factors that constitute professional behavior in faculty members. Data was analyzed by using SPSS software (version 23.0).

RESULTS:

In the first phase, the questionnaire with 11 items was developed. The validity and reliability of the tool was confirmed. The mean (SD) of the faculty members' scores was 4.54(±0.34), with a minimum score of 2.33 and a maximum score of 5.00. The highest scores of faculty members were reported in the items of “altruism to colleagues and students” and the lowest scores were related to “feedback seeking and feedback acceptance”. Professional behavior was categorized under two domains: accountability to professional duties and adherence to professional values. Fifty percent of the participants followed the adherence to professional values (P = 0.22), but less than 50% of the individuals followed the adherence to professional duties significantly (P = 0.002).

CONCLUSION:

The results of the present study showed that adherence to professional duties was low in faculty members. Assessment of individuals' adherence in these two domains showed that faculty members' compliance in the domain of accountability to professional duties was significantly lower.
The relationship between personality traits and learning styles in medical education students at Iran University of Medical Sciences: A cross-sectional study
Authors: Sohrabi Zohreh , Bigdeli Shoaleh , Nadjafi Shabnam
Published: January 2023

BACKGROUND:

The relationship between personality traits and learning styles is an attractive subject for researchers. “Learning Style” indicates on a method of education for effective studying. The Kolb's Learning Style is a known theory in the field of learning style. The Kolb's four learning styles include: Divergent, convergent, assimilating, and accommodating. Furthermore, personality, known as relatively fixed and durable characteristics that distinguish people from each other, and personality contains five broad identified traits of extraversion, agreeableness, openness, conscientiousness, and neuroticism. In this study, we intended to evaluate the relationship between personality traits and learning styles in medical education students.

MATERIALS AND METHODS:

This research was an observational analytic cross-sectional study that was conducted on medical education students at Iran University of Medical Sciences, between 2018 and 2019, and 31 students were participated as volunteers. NEO Five-Factor Inventory and the Kolb's learning style inventory (version 3.1) were used to evaluate the students' personality traits and learning styles, respectively. The simple and multiple analysis of multinomial logistic regression were used for statistical analysis.

RESULTS:

The results indicated that if one unit would be added to the score of the “Extraversion” personality trait, the estimated odds, by which the student's learning style would become “Accommodating” rather than “Assimilating,” is 1.3 times more than the basic condition, in which “Extraversion” score would be remained unchanged (P = 0.035).

CONCLUSION:

It seems that “Accommodating” learning style might be related to “Extraversion” personality trait in medical education students. However, researches with a larger population are suggested.

Published: January 2023

BACKGROUND:

Accurately predicting the intubation risk in COVID-19 patients at the admission time is critical to optimal use of limited hospital resources, providing customized and evidence-based treatments, and improving the quality of delivered medical care services. This study aimed to design a statistical algorithm to select the best features influencing intubation prediction in coronavirus disease 2019 (COVID-19) hospitalized patients. Then, using selected features, multiple artificial neural network (ANN) configurations were developed to predict intubation risk.

MATERIAL AND METHODS:

In this retrospective single-center study, a dataset containing 482 COVID-19 patients who were hospitalized between February 9, 2020 and July 20, 2021 was used. First, the Phi correlation coefficient method was performed for selecting the most important features affecting COVID-19 patients' intubation. Then, the different configurations of ANN were developed. Finally, the performance of ANN configurations was assessed using several evaluation metrics, and the best structure was determined for predicting intubation requirements among hospitalized COVID-19 patients.

RESULTS:

The ANN models were developed based on 18 validated features. The results indicated that the best performance belongs to the 18-20-1 ANN configuration with positive predictive value (PPV) = 0.907, negative predictive value (NPV) = 0.941, sensitivity = 0.898, specificity = 0.951, and area under curve (AUC) = 0.906.

CONCLUSIONS:

The results demonstrate the effectiveness of the ANN models for timely and reliable prediction of intubation risk in COVID-19 hospitalized patients. Our models can inform clinicians and those involved in policymaking and decision making for prioritizing restricted mechanical ventilation and other related resources for critically COVID-19 patients.

Published: January 2023

BACKGROUND AND AIM:

Given the complexities of the health care system and the importance of the subject and effects of health literacy in all aspects of care, defining specific health literacy in this context seems necessary. The purpose of this research was to explain the concept of hospital health literacy (HHL), its definition, and the related dimensions using the qualitative research method.

MATERIALS AND METHODS:

An exploratory qualitative design was used. Exploratory, open-ended, and face-to-face interviews based on the interview guide were used to elicit participants' perspectives between July 2021 and January 2022. By using the content analysis method, researchers coded transcripts and collated these codes into sub-categories and then merged them into the main category and explored the dimensions of the concept.

RESULTS:

A total of 23 service providers and 25 service recipients were included in the study. Analysis of qualitative data led to the identification of 6 categories and 25 sub-categories including cognitive literacy, functional (basic) literacy, communicative literacy, behavioral literacy, media literacy, and emotional literacy.

CONCLUSION:

The findings of the present study provide a deep understanding of the concept of HHL that could be applied to develop valid and reliable measurement tools for assessing HHL among a variety of populations. Also, it is hoped that the present attempt can be useful to guide future research and interventions as well as to provide a clear base for planning, implementing, and evaluating interventions aimed at promoting individuals' health literacy in health settings.
Awareness, knowledge, and psycho-emotional aspect of infertility among women seeking fertility assistance at a tertiary care hospital in Chhattisgarh, a cross-sectional study
Authors: Singh Vinita , Rajpal Gitika , Majumdar Sagarika , Mandal Sucharita , Sahu Rajshree
Published: January 2023

BACKGROUND:

The lack of fundamental knowledge and awareness about the biological process of reproduction is low worldwide but has reportedly higher incidence rates in under-developed countries. Infertility can have a tremendous effect on a woman's psychological and social well-being, pushing her toward mental stress, anxiety, depression self-blame, self-isolation, feeling of worthlessness, and lack of interest in life. The present study was conducted to determine the level of knowledge and awareness regarding factors affecting fertility and also to ascertain the emotional status of females visiting the Obstetrics and Gynecology out-patient department for fertility assistance.

MATERIALS AND METHODS:

A cross-sectional study was performed by using a questionnaire which had two parts; the first part had questions about awareness and knowledge of the subject of infertility, and the second part had 12 questions that assessed the psychological and emotional status of the participants, and it also explored prevailing myths about infertility based on a validated questionnaire.

RESULTS:

There was a significant difference in mean knowledge score; those who were more educated had better knowledge of various aspects of infertility. The overall adequacy for knowledge and awareness revealed that only 62 (47.7%) of the participants had adequate knowledge (score >6) regarding female infertility. The mean score for knowledge among all the respondents was 6.61 ± 1.48. The overall emotional and psychological score suggested that 30 (23%) of the respondents were disturbed because of stress because of infertility.

CONCLUSION:

Infertility can have a serious impact on the psychological well-being of females, and social pressure and stigma associated with childlessness can further worsen the physical and emotional well-being of couples, which needs to be addressed before starting treatment of infertility for a better response to treatment. The limited knowledge and prevailing mis-conceptions regarding infertility need to be sincerely dealt with to complement the medical treatment of infertility.
An exploratory study of the clinical technology undergraduate program in South Africa: Preparedness of students for clinical practice
Authors: Prakaschandra Dorcas Rosaley , Meyer Rhoda , Bhagwan Raisuyah
Published: January 2023

BACKGROUND:

This study sought to understand whether the theoretical components of the curriculum prepared students for clinical practice training in the Bachelor of Health Sciences (BHSc) in Clinical Technology program at the Durban University of Technology.

MATERIALS AND METHODS:

Two samples were recruited, namely, academics and students using non-probability sampling methods. The first sample comprised 13 students, and the second sample included four academics, involved in teaching and supervising the placement of students at healthcare institutions. At least one student from each of the 13 units where clinical practice training was undertaken was invited to participate. Data was gathered using in-depth, semi-structured interviews on an adapted version of Gibbs' cycle of reflection.

RESULTS:

Three broad themes emerged, namely, curriculum structure, factors that enabled graduate attribute development in the clinical environment, and the transition to online teaching.

CONCLUSION:

While it appears that the curriculum had in many ways prepared students for clinical practice, the study highlights key issues that may guide curriculum developers when seeking to improve preparedness of students for clinical practice. Furthermore, it underscores the need for continuous review of current curricula so that these are responsive to student and societal needs.

Abstract

Background:

Multiple level split cord malformations (SCMs) with associated skeletal abnormality are rare. Here we discuss a 3-year-old male child with double-level SCM type 1 and developmental dysplasia of the hip joints.

Case:

A 3-year-old male child presented with chronic constipation since birth with urinary incontinence. There was gait abnormality and he could not able stand without support. Radiology showed SCM type 1 at the level of D9-11 and L4. X-ray showed left dysplastic hip joints. Surgically both the bony spurs were resected and dural sac was repaired along with detethering of the low-lying filum. Orthopedic intervention was done after 3 months. At 18-month follow-up the child has improved bowel and bladder symptoms and could able to walk independently.

Conclusion:

Though rare, skeletal abnormalities like dysplastic hip joints may be associated with SCM. Early diagnosis and management of both conditions have better outcomes.
Poskus ocene kakovosti podtalnice v vodonosniku ob Mislinji
Authors: Breznik Jana , Trobec Tajan
Published: January 2023

Vodonosnik ob Mislinji zaradi majhne izdatnosti in dejstva, da se ne uporablja za vodooskrbo, ni vključen v redni državni monitoring kakovosti podzemnih voda. V članku na primeru devetih vzorčnih mest (zasebnih vodnjakov in vrtin) analiziramo vrednosti osnovnih fizikalno-kemijskih parametrov vode, na podlagi katerih preliminarno ocenjujemo njeno kakovost. Ugotavljamo, da se v podtalnici odražajo antropogeni vplivi, ki so izrazitejši v bližini območij strnjene kmetijske obdelave ter ob večjih naseljih. Pri večini vzorcev so prisotne povišane vrednosti nitratov in kloridov, pri nekaterih pa se v višjih koncentracijah pojavljajo tudi druga merjena onesnažila. Glede na aktualni Pravilnik o pitni vodi je kar pet od devetih vzorcev neustreznih, oziroma zgolj pogojno ustreznih, kar pomeni, da je podtalnica v vodonosniku ob Mislinji morda že preveč onesnažena, da bi nanjo lahko računali kot na možni rezervni vodni vir za vodooskrbo.

Authors: BOYACIOĞLU Nurcan , ÖZKAN Sultan
Published: January 2023

Peritoneal yüzey malignitelerin de yeni tedavi yaklaşımı sitoredüktif cerrahi ile birlikte kombine hipertermik intraperitoneal kemoterapi uygulamasıdır. Sitoredüksiyon cerrahi ile tüm makroskopik tümörlerin çıkarılması, Hipertermik İntraperitoneal Kemoterapi (HİPEK) ile de mikroskobik tümör hücrelerinin yok edilmesi amaçlanmaktadır. Bu yöntem, plazma-periton bariyerini kullanarak kemoterapötik ajanların ısı ile birlikte daha yüksek konsantrasyonlarda ve daha az sitotoksik yan etki ile uygulanmasına olanak sağlamaktadır. Ancak işlem esnasında ameliyathane çalışanlarının kemoterapötik ajanlar ile maruziyet riski söz konusudur. Bu derlemede HİPEK işlemi esnasında maruziyet yolları ve çalışanların sağlığını korumaya yönelik güvenlik önlemleri konusunda literatür bilgileri ele alınmıştır.

Las tramas materiales de la autonomía indígena. Un análisis sobre las disputas históricas por la apropiación de los bienes comunes en Cherán, México
Authors: Martínez Navarrete Edgars
Published: January 2023

Aquí se examina la manera en que el proceso de autonomía indígena de Cherán logró desmontar el régimen de violencia y despojo al que estuvo sometida la comunidad producto de la incursión gradual del crimen organizado desde el año 2007, el cual buscaba generar las condiciones socio-territoriales para la expansión de la agroindustria aguacatera en Michoacán (México). Se propone comprender este fenómeno como una deriva contemporánea de un proceso histórico de apropiación ejercido por numerosas estructuras capitalistas sobre los recursos boscosos de la Meseta Purhépecha, la cual ha diluido las lógicas productivas comunales y los entramados subjetivos tanto de Cherán como de las comunidades que mantienen una relación material con el bosque en la región. Se sostiene que el carácter autonómico – y antagónico - de esta experiencia radica en el impulso de iniciativas económico-políticas capaces de desplegar un grado de disputa, por un lado, a la lógica del valor de cambio a nivel local y, por otro, a las añejas modalidades de la política convencional que han sido responsables de fuertes conflictos en la comunidad a lo largo de su historia.
Trabajo interdependiente, comunes territoriales y precariedad política en zonas extractivas de Ecuador y Bolivia
Authors: Cielo Cristina , López Canelas Elizabeth
Published: January 2023

Este capítulo examina las dimensiones laborales y políticas de las trabajadoras no asalariadas en las periferias extractivas de Bolivia y Ecuador, para mostrar cómo la apropiación racializada del trabajo de mujeres es un aspecto fundacional de la lógica extractiva del capital. Consideramos la extracción en su sentido más amplio como el despojo no solo de recursos, sino también del trabajo socialmente producido de las economías populares y reproductivas. En ese sentido, exploramos las jerarquías naturalizadas raciales y de género fundamentales para el despojo de comunes territorializados producidos por, y necesarios para, las actividades interdependientes para sostener la vida. Argumentamos que las lógicas extractivas no solo se apropian del trabajo de las mujeres y las poblaciones racializadas, sino también de estos territorios literal y figurativamente comunales, individualizando los medios de vida y aumentando la vulnerabilidad física, económica y subjetiva. En estos contextos de violencia cotidiana, las resistencias constituidas desde lo común no están exentas de las contradicciones y desigualdades del despojo.
Formación colonial del Estado y despojo en Ngulumapu
Authors: Nahuelpán Moreno Héctor
Published: January 2023

Este capítulo analiza el proceso de formación colonial del estado chileno en territorio mapuche, específicamente en Ngulumapu, territorio ubicado al oeste de la Cordillera de los Andes. Profundiza en las dinámicas de despojo capitalista o formas de “acumulación originaria” que explican la expoliación territorial, la conformación de los mercados urbanos y locales, las formas de disciplinamiento y explotación de los mapuche como mano de obra racializada. Se argumenta que las relaciones entre despojo, colonialismo, capitalismo y formación del estado como proceso histórico, están en la médula de las condiciones de opresión del pueblo mapuche y su comprensión es crucial para la lucha de liberación y descolonización en la actualidad. La evidencia que sostiene los análisis, corresponde a fuentes históricas recopiladas en archivos estatales oficiales, como Memorias de los Ministerios de Guerra, Marina, Interior, Colonización; así como periódicos y correspondencia epistolar de Lonkos (líderes) mapuche.
Lo territorial, lo comunitario y los comunes frente al despojo extractivista en América Latina: aproximaciones al debate teórico-político de la CLOC-Vía Campesina
Authors: Pinheiro Barbosa Lia
Published: January 2023

El escrito plantea una reflexión de cómo La Vía Campesina (LVC), en particular, su representación regional —la Coordinadora Latinoamericana de Organizaciones del Campo (CLOC)— han situado lo territorial, lo comunitario y los comunes frente al despojo extractivista y cómo articulan un proceso de defensa de los territorios en escala transnacional y global. Un argumento central consiste en situar la CLOC/LVC como un sujeto comunitario transnacional que eleva a una escala transnacional y global lo territorial, lo comunitario y los comunes en la conformación de una estrategia y táctica de enfrentamiento del capitalismo agrario. En ese proceso, lo territorial, lo comunitario y los comunes incorporan un sentido multiescalar y expresan el entretejer de una concepción de los territorios enmarcada en otro paradigma de conocimiento, un Paradigma Onto-epistémico del Campo, que articula las matrices ontológicas, epistémicas y políticas para tejer esa concepción territorial y articular la unidad política de un proceso de resistencia en contextos de diversidad y heterogeneidad propios de esos territorios.

Authors: Quiñones Negrete Magaly Margarita , Martín Cuadrado Ana María , Coloma Manrique Carmen Rosa
Published: January 2023

El presente libro es el resultado del trabajo de investigación: Las competencias genéricas, las estrategias de aprendizaje de estudiantes de Educación Superior y los estilos docentes donde se buscó analizar su influencia en el rendimiento académico mediada por un entorno virtual; realizado en una universidad privada de la ciudad de Chimbote en Perú en el segundo semestre del 2019. El objetivo principal fue determinar la relación existente de las estrategias de aprendizaje, competencias genéricas y estilos de aprendizaje con el rendimiento académico del estudiante en entornos virtuales, teniendo en cuenta la competencia digital y estilo docente de una universidad privada del Perú, 2019. Para este propósito se utilizó un tipo de investigación cuantitativa y retrospectiva, dado que la información se recolectó después de los hechos reportados y fue medida numéricamente. Asimismo, se aplicó un nivel de investigación analítico-correlacional multivariado de corte transversal, donde se determinó en qué medida las variables competencias genéricas, estilos y estrategias de aprendizaje están relacionadas con el rendimiento académico entre sí en un solo periodo de tiempo. En la totalidad de estudiantes que participaron en el estudio se encontró que las variables que mostraron tener influencia directa y positivamente en el rendimiento académico fueron el estilo de aprendizaje trabajo cooperativo y competencia digital. Asimismo, las dimensiones de las variables del estudiante que más predominan e influyen directa y positivamente en el rendimiento académico son: 1) estilo de aprendizaje activo y reflexivo 2) estrategia de búsqueda de selección, 3) concepción del trabajo en grupo, utilidades del trabajo en grupo para su formación, 4) estrategias de participación y 5) conocimiento de las Herramientas virtuales y de comunicación social de pregrado y uso de medios tecnológicos.
