L’épistémologie épicurienne dans le De rerum natura : rigueur et créativité
Authors: Kany-Turpin José
Published: November 2023

Lucrèce adopte résolument les principes de l’épistémologie d’Épicure mais il n’en explicite guère les procédures et le vocabulaire qu’il emploie pour en traduire les termes spécifiques n’est pas toujours cohérent, ce qui entraîne quelques difficultés et des innovations. Après cette présentation générale, on étudiera certaines analogies dans lesquelles Lucrèce infléchit la méthode d’inférence épicurienne. L’usage spécial des analogies à des fins scientifiques semble même la marque de la créativité méthodologique du poète latin. On tentera donc finalement d’évaluer l’intérêt que présente cette méthode pour la compréhension de la doctrine d’Épicure, en particulier dans ses aspects les plus complexes.
Réminiscence et connaissance a priori
Authors: Delcomminette Sylvain
Published: November 2023

Cet article se propose de confronter la réminiscence platonicienne à la connaissance a priori kantienne. Pour ce faire, après avoir rappelé la différence entre connaissance a priori et connaissance innée selon Kant, il se tourne vers l’interprétation néokantienne de la réminiscence platonicienne par Paul Natorp. Il montre ensuite, en examinant en particulier des passages du Phédon et du Théétète , que le point le plus critiquable de l’interprétation de Natorp est moins sa compréhension de la connaissance atteinte par la réminiscence platonicienne comme étant a priori que comme étant transcendantale.
Mémoire reconnue et mémoires méconnues du conflit armé colombien : le cas du massacre de Trujillo
Authors: Lavielle Julie
Published: November 2023

Si la construction de récits publics sur les passés violents est amplement étudiée, la manière dont ces récits interfèrent avec les représentations des groupes auxquels ils s’adressent et dont ils parlent reste peu explorée. Les rapports entre les mémoires locales du massacre du village colombien de Trujillo et une mémoire historique élaborée par une association de victimes qui a acquis une reconnaissance nationale et internationale sont étudiés ici dans une perspective de sociologie de la mémoire. L’enquête empirique révèle qu’il existe un décalage entre cette mémoire historique et les mémoires locales. La faible légitimité de l’association dans le village et l’étiolement des relations entre ses membres ouvrent en effet la voie à une pluralité de façons de se remémorer le massacre. Dès lors apparaissent les limites du récit commun centré sur la souffrance des victimes que l’État colombien essaie de construire depuis les années 2000 : si la douleur des victimes et la construction de la paix semblent être des impératifs à l’échelle nationale, la violence est localement perçue comme fatale et demeure parfois justifiée par les habitants.
Maîtriser « l’esprit du costume » : apprendre et s’approprier la tradition en pays d’Arles
Authors: Marcia Elise
Published: November 2023

Le costume traditionnel féminin du pays d’Arles connaît, depuis les années 1970, une complexification croissante. Sa forme, ses couleurs et ses tissus sont formalisés par des historiennes locales et font l’objet d’une transmission rigoureuse. Les Arlésiennes qui le portent aujourd’hui y sont très attachées et s’investissent dans sa particularisation. Autour de ce costume, des socialisations, des apprentissages et initiations se jouent, notamment dans le cadre de groupes de couture spécialement dédiés. Les jeunes filles sont guidées dans leur parcours par leurs aînées, tandis qu’elles tentent, de leur côté, de s’approprier l’habit traditionnel local.
Les pratiques alimentaires et sportives au sein des salles de fitness non mixtes. Entre transmission, partage et appropriation
Authors: Louchet Cindy
Published: November 2023

S’appuyant sur des entretiens semi-directifs et des observations participantes et non participantes issus d’un travail doctoral, cette contribution propose d’analyser la transmission des connaissances inhérentes aux pratiques de remise en forme, incluant à la fois une dimension sportive et alimentaire, au sein des salles de fitness non mixtes. Ces espaces singuliers, au regard de la séparation des sexes opérée, s’avèrent plus qu’ailleurs propices aux partages d’expériences et de connaissances acquises et/ou incorporées entre les professionnels et leurs clientes ainsi qu’entre pratiquantes en faisant avant tout des lieux d’échanges.
L’eusko basque, une monnaie qui divise
Authors: Fois Duclerc Mathilde , Maclouf Marguerite
Published: November 2023

Les monnaies locales qui se sont multipliées en France depuis 2010 s’insèrent dans un ensemble plus large d’actions collectives fondées sur une critique de la globalisation des activités économiques et notamment des circuits de distribution agro-alimentaires. Cet article analyse les logiques contestataires sous-jacentes à la participation d’agriculteurs et agricultrices à un tel mouvement. À partir du cas de l’eusko au Pays Basque, l’article expose la manière dont une fraction mobilisée du monde agricole s’intègre dans un réseau monétaire alternatif, sous l’effet d’une interaction entre un travail militant mené par l’association porteuse de la monnaie locale et des formes d’actions collectives propres au monde rural local. En montrant que l’acceptation de cette monnaie s’articule à des positions dans les clivages syndicaux territoriaux plus qu’à une unité de pratiques productives, il propose une contribution à l’analyse de l’ancrage social et politique des dispositifs techniques.
Sculptures médiévales en pierre de l'Hôtel de Ville de Bruxelles
Authors: Anagnostopoulos Pierre
Published: November 2023

Les sculptures en pierre de quatre secteurs de l‘Hôtel de Ville datant des phases de construction des xiv e et xv e siècles ont fait l’objet d’une investigation d’ensemble, jamais menée jusqu’ici. Le secteur du passage couvert montre toute l’hétérogénéité des sculptures provenant de différentes périodes, principalement du xv e siècle, avec notamment des liens avec les productions de l’atelier de Jan ii Borreman. Face à la Grand-Place, le portique de l'aile orientale nous offre un échantillon de sculptures figuratives que l'on peut dater des premières années du xv e siècle. Elles représentent des personnages tantôt armés, tantôt en habit drapé, témoignant de styles parfois très différents. Des rapprochements peuvent être effectués avec des sculptures de production bruxelloises pour des monuments contemporains édifiés à Malines. Le portique occidental, lui, est un exemple majeur de la sculpture bruxelloise vers le milieu du xv e siècle. Corbeaux et chapiteaux répartis en trois cycles thématiques distincts, styles et techniques mises en œuvre sur ces sculptures, de même que plusieurs moulures spécifiques sont les témoignages majeurs de la sculpture et des ornements produits à Bruxelles au milieu du xv e siècle. Enfin, trois culs-de-lampe de la tour, à structures en encorbellement, ont fait l’objet d’une recherche complémentaire, mettant en évidence les sujets représentés, leur datation possible et leurs spécificités dans la construction.

Le plaidoyer des personnes en situation de handicap pour l'ODD 16+
Authors: Baranyi Stephen , Simo Axel Pueugue
Published: November 2023

L'Agenda 2030 a suscité l'enthousiasme mais aussi d'intenses débats. Les optimistes perçoivent les Objectifs de développement durable (ODD) comme les leviers d’un effort mondial visant à ne laisser personne de côté. Les pessimistes craignent que les ODD alignent les politiques de développement sur un projet néolibéral. Cet article explore les débats entre ces visions, en examinant la logique qui sous-tend le plaidoyer des organisations de personnes en situation de handicap (OPH), en faveur des ODD. Il triangule l'analyse de leur activisme au niveau mondial, au Canada et en Haïti. S'appuyant sur un cadre théorique institutionnaliste critique et intersectionnel, il conclut que si le positionnement stratégique des OPH transnationales pour les ODD est compréhensible et contribue modestement à leurs luttes dans des contextes favorables comme le Canada, il est peu probable que qu’il en soit de même dans des contextes contraignants comme celui d’Haïti.

Objective:

To assess the prevalence of Mycobacterium (M.) tuberculosis infection and its associated risks in children under fifteen years of age.

Methods:

Based on secondary data from the 2018 Indonesian Basic Health Survey (RISKESDAS 2018), this cross-sectional study employed M. tuberculosis infection in children as a dependent variable and age level, sex, region, location, family case positive, and smoking as independent variables. Geospatial analysis was applied to show the prevalence of M. tuberculosis infection and multivariate regression was performed to analyze the risk factors of getting the infection among children under 15 years of age.

Results:

Prevalence ranges of M. tuberculosis infection among children aged 0-14 years, babies (age <12 months), toddlers (age 12-59 months), and children aged between 5 and 14 years were 0.03% to 0.57%, 0% to 0.64%, 0% to 0.78%, and 0.01% to 0.53%, respectively in Indonesia. A high prevalence of M. tuberculosis infection among children under 15 years of age was found in Papua and other provinces, such as Kalimantan and Java. Contacting with tuberculosis family members was positively associated with M. tuberculosis infection in children as shown by multivariate logistic regression (OR 8.94; 95% CI 5.4-14.6, P<0.05).

Conclusions:

Contacting with family member who has tuberculosis is related with M. tuberculosis infection among children in Indonesia. Therefore, screening the household for contact with tuberculosis patients is a preventive treatment for children.
Explore the role of long noncoding RNAs and mRNAs in intracranial atherosclerotic stenosis: From the perspective of neutrophils
Authors: Wang Yilin , Wang Tao , Han Ziping , Wang Rongliang , Hu Yue , Yang Zhenhong , Shen Tong , Zheng Yangmin , Luo Jichang , Ma Yan , Luo Yumin , Jiao Liqun
Published: November 2023

CONTEXT:

Circulating neutrophils and long noncoding RNAs (lncRNAs) play various roles in intracranial atherosclerotic stenosis (ICAS).

OBJECTIVE:

Our study aimed to detect differentially expressed (DE) lncRNAs and mRNAs in circulating neutrophils and explore the pathogenesis of atherosclerosis from the perspective of neutrophils.

METHODS:

Nineteen patients with ICAS and 15 healthy controls were enrolled. The peripheral blood of the participants was collected, and neutrophils were separated. The expression profiles of lncRNAs and mRNAs in neutrophils from five patients and five healthy controls were obtained, and DE lncRNAs and mRNAs were selected. Six lncRNAs were selected and validated using quantitative reverse transcription–polymerase chain reaction (qRT-PCR), and ceRNA and lncRNA-RNA binding protein (RBP)-mRNA networks were constructed. Correlation analysis between lncRNAs and mRNAs was performed. Functional enrichment annotations were also performed.

RESULTS:

Volcano plots and heat maps displayed the expression profiles and DE lncRNAs and mRNAs, respectively. The qRT-PCR results revealed that the four lncRNAs showed a tendency consistent with the expression profile, with statistical significance. The ceRNA network revealed three pairs of regulatory networks: lncRNA RP3-406A7.3-NAGLU, lncRNA HOTAIRM1-MVK/IL-25/GBF1/CNOT4/ANKK1/PLEKHG6, and lncRNA RP11-701H16.4-ZNF416. The lncRNA-RBP-mRNA network showed five pairs of regulatory networks: lncRNA RP11-701H16.4-TEK, lncRNA RP11-701H16.4-MED17, lncRNA SNHG19-NADH-ubiquinone oxidoreductase core subunit V1, lncRNA RP3-406A7.3-Angel1, and lncRNA HOTAIRM1-CARD16.

CONCLUSIONS:

Our study identified and verified four lncRNAs in neutrophils derived from peripheral blood, which may explain the transcriptional alteration of neutrophils during the pathophysiological process of ICAS. Our results provide insights for research related to the pathogenic mechanisms and drug design of ICAS.
Spontaneous and induced degradation of dermal fillers: A review
Authors: Wollina Uwe , Goldman Alberto
Published: November 2023

Dermal fillers are among the most versatile tools in esthetic medicine. A broad range of temporary, semipermanent, and permanent filler products is on the market. We performed a narrative review on spontaneous and induced degradation of dermal fillers in vitro and in vivo. Hyaluronic acid-based fillers are the most frequently used temporary fillers. The products differ in their hyaluronic acid content, cross-linking, and rheological parameters. Endogenous hyaluronidase and reactive oxygen species are responsible for the spontaneous degradation of these fillers. Hyaluronidase digests the filler material by cleavage of the β-1,4 glycosidic linkage between N-acetyl-glucosamine and d-glucuronic acid. The enzyme can be used for treatment of medical and cosmetic adverse events due to hyaluronic acid-based filler. Higher hyaluronidase content and higher degree of cross-linking are major factors contributing to filler persistence over time. Semipermanent fillers are poly-(d),l-lactic acid and calcium hydroxylapatite. These filler types are decomposed by hydrolysis and osteoclastic enzymes. They usually persist up to 2 years, in single patients even more than 5 years. Sodium thiosulfate can stimulate degradation of calcium hydroxylapatite, but it is slow acting and not effective in case of emergency. Permanent fillers may show some kind of modification in situ, but spontaneous or induced degradation has not been documented. Once implanted the permanent fillers remain lifelong. Intralesional laser treatment supports the removal of permanent filler material as an alternative to surgery. Besides biocompatibility and toxicity, filler materials should also be assessed for degradation to improve patient safety.

Published: November 2023

This systematic review aimed to evaluate the effect of telerehabilitation on improving physical activity, physical function, and quality of life in patients with osteoarthritis (OA). A systematic review of randomized controlled trial studies was conducted without a time limit by searching for keywords in the title, abstract, and study keywords in the scientific databases Embase, Web of Science, Scopus, and PubMed on October 20, 2021. This study was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Titles and abstracts were retrieved based on the inclusion, exclusion, and quality assessment criteria. Then, full texts were retrieved and reviewed independently by two separate authors based on the eligibility criteria. Disputes were resolved through discussion. A form with the same predefined elements was used to extract data. Totally, eight eligible articles were found through this review. The studies on telerehabilitation approaches were categorized into three categories, which are: home-based exercise programs by online mobile applications, sports counseling and physiotherapist support via telephone calls, and Internet-based exercise training (IBET). In four studies (57%), telerehabilitation was effective in the short term for some months and improved the performance, self-efficacy, and quality of life of participants. On the other hand, in the long-term effects, there was no difference in participants' improvement (43%). In long-term follow-up, there was no difference between the efficiency of traditional rehabilitation and telerehabilitation in improving the physical performance and quality of life. However, telerehabilitation can be a viable alternative to traditional physiotherapy in patients with OA.

Published: November 2023

The quality of emergency services is one of the indicators describing the health status of countries. Moreover, the specialization of services and targeted response to any accident or disease has been the priority of pre-hospital emergency operations in some leading countries. This study aimed to compare the special services provided in the emergency department of several selected countries. This was a comparative study that was done in Isfahan in 2022. Data were collected by reviewing the literature provided by libraries and emergency websites of selected countries. We selected countries based on the accessibility of information in two groups of developed countries and countries with the same income and population as Iran including Germany, France, The United States, Australia, Britain, Malaysia, and Turkey. Data were classified and compared based on staff, vehicles, and specialized services. Emergency staffs in most countries were of different skill and training levels. Ambulances varied in equipment types in various land, air, and sea forms and dimensions. Developed countries had more modern ambulances and equipment. France and Germany were operating more especially. Specialized teams are dispatched only in the United States and Germany. Existing studies have shown the adequacy and effectiveness of these teams in reducing complications and mortality and improving the prognosis of patients. The use of specialized teams appropriate to each emergency based on the specific and targeted response is effective in improving the prognosis of patients. The results of this study are suggested to beneficiaries to improve the quality of emergency care and reduce complications and potential causalities.
Microbiological Profile of Infectious Keratitis in a Tertiary Care Hospital
Authors: Sharma Alisha , Sati Alok , Bhatt Puneet , Ninawe Sandeep , Mahajan Pooja , Patel Ankita , Bahal Ashish
Published: November 2023

Background:

Microbial keratitis is a major preventable cause of visual impairment. In developed countries viral infections are the leading cause of corneal ulcer whereas bacteria and fungi attributes to maximum number of cases in the developing countries. There is paucity of recent data, risk factors and demographic distribution of patients for all three leading etiological agents of keratitis.

Material and Methods:

This study included all clinically diagnosed cases of infective keratitis from 01 Jan 2021 to 01 Jan 2022. In brief, four sets of corneal scrapings were taken from patients of infectious keratitis and processed for bacterial and fungal culture, microscopy and RTPCR of viral agents.

Results:

It was observed that rural elderly males were the most predisposed to occurrence of infectious keratitis and trauma being the leading cause. Out of total 151 samples processed, 49(32%) samples were found to have definitive evidence of bacterial, fungal and viral pathogens. Fungi were found to be the most common 37 (24%) etiological agent leading to keratitis followed by bacterial 7(5%) and viral agents 5(3%).

Conclusion:

Clinical signs alone are not sufficient to diagnose infectious keratitis, the importance of microbiology in the identification of pathogen and aiming at definitive therapy of infectious keratitis helps in rescuing the eye from this reversible cause of blindness.
Subcutaneous Implantable Cardioverter-defibrillator in Preventing Ventricular Arrhythmia and Sudden Cardiac Death – A Single-center Experience
Authors: Jayachandra Amarapalli , Datta Rajat , Issar Neel Kanth , Sharma Prabhat
Published: November 2023

Introduction:

Subcutaneous implantable cardioverter-defibrillator (S-ICD) differs from the transvenous ICD (TV-ICD) system in its extrathoracic and extravascular localization, eliminating the risks arising from vascular access and leading to fewer complications. The objective was to describe the functionality and postoperative complications associated with SICD implants in patients with cardiac dysfunctions.

Methods:

We enrolled six patients eligible for SICD due to either anterior wall myocardial infarction or left ventricular dysfunction, who reported to our tertiary cardiac care center from June 2020 to March 2022. Preprocedural evaluation for various cardiac parameters was carried out. The procedure was performed under antibiotic prophylaxis. Two incision techniques were used for the SICD placement. The primary and secondary endpoints for the cases were set to evaluate device-related complications and predictive outcomes, respectively.

Results:

Subcutaneous implantable defibrillator was placed in six male patients aged 36−51 years. The procedure demonstrated an efficient, reliable, and well-accepted modality in eliminating ventricular tachycardia, ventricular fibrillation, and sudden cardiac death. In addition, postoperative complications, such as device infection, pocket hematoma, blood transfusion, prolonged hospitalization, cardiac perforation or tamponade, lead repositioning, or inappropriate shocks, were not reported in the 2 years of follow-up.

Conclusion:

Subcutaneous implantable defibrillator promises to offer a suitable and safer option for TV-ICD, especially in young patients. It circumvents the need to enter the vasculature or cardiac chambers. As a result, fewer reported lead-related complications, better cosmetic appearance, and greater immediate postoperative comfort as it permits free shoulder movement.
Etiology of acute respiratory infections using multiplex polymerase chain reaction in children admitted to pediatric intensive care unit: A single-centered retrospective observational study from Western India
Authors: Barchha Shivam , Shobhavat Lakshmi , Solomon Rekha , Harnal Shivanand
Published: November 2023

Background:

Acute respiratory infections (ARIs) are an important cause of pediatric mortality–morbidity worldwide, the most common etiology being viral. This study aims to identify causative organisms for ARIs admitted in pediatric intensive care unit (PICU), when multiplex polymerase chain reaction (PCR) testing of respiratory secretions was sent; any seasonal trends detect microbiological correlation when co-infections.

Subjects and Methods:

This was a retrospective observational study, from July 2021 to December 2022, of children aged 1 month–18 years, whose multiplex PCR tests (nasopharyngeal, endotracheal [ET] secretion or bronchoscopic alveolar lavage [BAL]) were sent when admitted for ARI to tertiary care PICU.

Results:

In the study period, 372 of 1492 medical PICU admissions were ARI. Multiplex PCR of 81 respiratory secretions was sent, of which 69 (85%) were positive. Multiplex pcr sample positivity : 83% for nasopharyngeal aspirate, 78% for ET secretions, 100% for BAL samples. Forty-one percent of samples detected >1 organism. Respiratory syncytial virus (RSV)-A was the most common virus (18); other organisms included adenovirus (n = 5), influenza (n = 9), parainfluenza (n = 5), rhinovirus: 13, Pneumocystis Jerovecci (PCP): 4, Streptococcus pneumoniae: 17, pertussis: 1, and Haemophilus
influenzae B: 9. ARIs were seen throughout the year with peaks in monsoon season and a peak in cases of ARI due to RSV from July to October. Of co-infections with bacteria in ET secretions and BAL samples via multiplex PCR, bacterial culture reports were sterile.

Conclusions:

Multiplex PCR detected organisms in 85% of ARI patients tested. Most of the ARIs getting admitted to PICU were viral in origin. RSV was the most common virus isolated showing peak from July to October, local monsoon season. With extended viral and bacterial PCR being available, mixed infections/colonization with uncertain significance are being detected.
Use of hypnotics for the management of insomnia in psychiatric patients: A clinical audit and review on Z-drugs
Authors: Kar Nilamadhab , Ohri Lakshmi Radhica , Mahil Jasmin , Merlici Sorina
Published: November 2023

BACKGROUND:

Insomnia is a common condition in patients with mental illness, for which hypnotic medications are regularly prescribed.

AIM:

It was intended to study the clinical practice of using hypnotic medications including Z-drugs for insomnia and compare it with treatment guidelines.

METHODS:

In this clinical audit, data were collected from the clinical records of patients who attended outpatient department in adult and old age psychiatric units in a mental health service.

RESULTS:

Out of the consecutive 203 patients screened, 50 (24.6%) were prescribed hypnotic/sedative drugs. It was observed that around half (54%) received nonpharmacological interventions for insomnia, 42% had psychoeducation, and 24% sleep hygiene. Zopiclone (56%) and promethazine (26%) were more commonly prescribed; however, lorazepam (14%) and diazepam (16%) were also used. In the majority of cases, these were prescribed on a “if required” basis. Duration of hypnotic prescription was specified in only 36%, whereas many patients continued these medications for months (26%) and years (26%).

CONCLUSION:

There is a scope to increase the use of nonpharmacological treatments for insomnia. Reviewing the period of use of hypnotic medications is essential as many patients continue them for longer durations than recommended. Treatment of insomnia needs focused attention in psychiatric clinics.
Survey of factors contributing to the happiness of older persons: A cross-sectional study of associated worries, anxiety, and depression
Authors: Kar Shreyan , Mahapatra Prasanta Kumar , Rath Namita , Kar Brajaballav , Das Tushar Kanti , Kar Nilamadhab
Published: November 2023

BACKGROUND:

Old age is associated with a greater prevalence of worry, anxiety, and depression when compared to the younger age groups. Age-specific stressors and comorbidities accumulate and negatively impact the well-being of older adults.

AIMS/OBJECTIVES:

In this context, we intended to study the factors influencing the happiness of older adults.

METHODS:

It was a survey through a questionnaire of older adults attending a public health conference on old age-related issues. We inquired about what makes them happy, their worries, and physical and mental health issues. We also assessed their depression through the Patient Health Questionnaire (PHQ-9), anxiety through the General Anxiety Disorder 7 (GAD-7) scale, and quality of life (QoL) using a scale of 0 being worst to 10 being best.

RESULTS:

Factors that brought happiness to older adults were family and friends (25.7%), social activities (28.6%), traveling and sightseeing (11.4%), reading and writing (11.4%), meeting people (8.6%), and having time for self (8.6%). Besides these, 22.9% reported they enjoy working. A clinical level of anxiety (GAD-7 score of 10 or more) was present in 17.2% and depression (PHQ-9 score of 10 or more) in 28.6% of older adults. The anxiety and depression scores were positively correlated (P < 0.001) in the sample studied. There were no differences between genders related to concerns, health, finance, relationships, memory, needs for help, QoL, and severity of anxiety or depression.

CONCLUSIONS:

Older adults could identify various factors linked to their happiness, despite various concerns and mental health issues. The information might help family, informal, and professional caregivers to support activities that contribute to the well-being and happiness of older adults.

Authors: Lamb M M , DeHority K , Russel S M , Kim S , Stack T , Mohammad I , Zeatoun A , Klatt- Cromwell C , Ebert Jr. C S , Baratta J M , Senior B A , Kimple A J
Published: November 2023

Background: A subset of individuals suffering from Coronavirus Disease 2019 (COVID-19) will experience ongoing symptoms that last longer than three months (i.e., long-haul COVID). This includes olfactory dysfunction (OD), which is currently estimated to occur in 1-63.5% of patients at one-year post-infection. However, OD in individuals with long-haul COVID-19 is poorly understood, and there is little information regarding how initial SARS-CoV-2 variants correlate with long-haul symptoms. In this study, we investigated the prevalence and severity of OD in patients with long-haul COVID-19 and investigated how OD severity varied with SARS-CoV-2 variants. Methods: Patients were recruited from the University of North Carolina-Chapel Hill COVID Recovery Clinic. Each patient com- pleted the University of Pennsylvania Smell Identification Test (UPSIT). The dominant strain at the time of infection was deter- mined using the date of COVID-19 diagnosis, and Centers for Disease Control and Prevention, World Health Organization, and North Carolina Department of Health and Human Services databases. Results: Nearly 85% of patients with long-haul COVID-19 reported some degree of OD, which persisted in some patients for two or more years from the date of the initial infection. There was no association between the time since COVID-19 infection and severity of OD. No difference was detected between OD in patients with long-haul COVID-19 based on the dominant variant at the time of infection. Conclusion: A vast majority of patients with long-haul COVID-19 had some degree of ongoing olfactory complications, although the severity of symptoms was not dependent on the dominant SARS-CoV-2 variant at the time of infection.
The earliest glass from the territory of Slovenia
Authors: Leghissa Elena , Šmit Žiga , Brezigar Barbara , Svetličič Vesna , Turk Peter
Published: November 2023

This paper presents the results of the analyses of three glass beads from three Bronze Age sites, Medvode-Svetje, Trata near Škofja Loka and Kamna Gorica near Ljubljana. All three sites belong to the Oloris-Podsmreka horizon, which covers the Middle and the beginning of the Late Bronze Age (c. second half of the 16th/first half of the 15th century to 12th century BC). The PIXE and PIGE analyses revealed that only two of the examined beads belong to the Bronze Age. The bead from the Medvode-Svetje site is similar to LMHK beads and is most likely an import from the Frattesina production centre in northern Italy, while the bead from the Trata site has similarities with the eastern Mediterranean or even Mesopotamian area HMg glass. The natron glass bead from Kamna Gorica is probably an Iron Age infiltrate in a Bronze Age layer.
Z vzgojiteljevo metodično kompetentnostjo do čustvene in bralne pismenosti
Authors: Bednjički Rošer Barbara
Published: November 2023

This article highlights the importance of emotional literacy using a variety of reading materials. Emotional-social development is a major characteristic with high predictive value for later academic and personal success, and plays a central role in the development of social competence in children. As it can be influenced, the incentives and opportunities offered to children by kindergarten teachers play an important role in emotional-social development. By taking into account the developmental characteristics of children, the methodological competence of teachers can constitute a starting point for emotional and social development through continuous guided work with picture books, as these are the most common forms of books in the pre-school period. Thematically and motivationally emotion-linked information, fiction and hybrid texts facilitate the acquisition, deepening, and expansion of knowledge and promote the development of emotional and reading literacy.
Literarnost Cankarjevih romanov in Križ na gori
Authors: Zupan Sosič Alojzija
Published: November 2023

Ivan Cankar saw the evaluation of literature as a necessary determination of the related literary system, and took into account the criteria of literariness in all his novels, as he did not adapt to didacticism, pragmatism, ideology and the hedonistic principle of entertainment. He also evaluated his own novels: of the three novels compared in this discussion, The Ward of Mary Help of Christians, Madame Judit, and The Cross on the Mountain, the last one is the lowest quality and aimed at the widest audience, something that was also acknowledged by the author. Above all, the non-innovativeness of the characterization in this work failed creative divisiveness and partially also multi-meaning, important criteria of literariness. The character of Hanca, humble and vitalistic, with the traditional image of a woman, along with the optimistic ending of the novel, suited the audience of the time with its predominantly trivial tastes. Hanca is not a classic femme fragile, a secessionist treatment of the female “angel of the house” gender stereotype, because despite her physical weakness she is internally strong and knows how to escape from a conventional environment, but her role is nevertheless too saintly and maternal. Cankar was probably aware of her partial stereotyping, as in the same year he created completely different, unconventional female characters in the novels The Ward of Mary Help of Christians and Madame Judit, which are also his best novels.

Authors: Ayad Rima , Ayad Radia , Zineddine Latifa , El Houda Berghida Nour
Published: November 2023

The main purpose of this study was to determine the proximate composition and physicochemical properties of Algerian wild green carob collected from three separate locations in Jijel province (northeast of Algeria), as well as to investigate its antioxidant potency. The results showed that the three samples were substantially comparable in terms of proximate compositions and physicochemical attributes. They have an acidic pH range and a very low fat content. In terms of phytochemical properties, Texenna green pods had the highest levels of polyphenols, flavonoids, and flavonols, with concentrations of 87.10 ± 0.07 μg GAE/mg DM, 4.90 ± 0.06 μg QE/mg DM, and 37.0 ± 0.19 μg QE/mg DM, respectively. Furthermore, the total antioxidant capacity of the methanolic extracts was determined using the phosphomolybdate method and found to be 154.62 µg AAE/mg DM. These promising findings revealed that unripe Ceratonia siliqua L. from the Texenna region is a rich source of natural antioxidants that could be employed more broadly in functional food formulations.

Published: November 2023

This work uses the sonochemical method to represent synthesized cobalt oxide nanoparticles (Co3O4) and analysed using different techniques. The X-ray diffraction analysis (XRD) and Fourier-transform infrared spectroscopy (FTIR) examinations of the synthesized nanoparticles confirmed their cubic structure and average crystallite size of 21.3 nm. The spherical surface shape and presence of components with a particle size of 25.3 nm were revealed. Scanning probe microscopy (SPM) methods analysed the Co3O4 coated plates' surface characteristics, including roughness and topographical ideas. An aqueous electrolyte medium (6 M KOH) was used to investigate the electrochemical corrosion behaviour of Co3O4-coated plates. According to the Tafel plot, coating Zn plates with a high surface area and mesoporous Co3O4 in KOH electrolytes greatly reduced the corrosion of the plates. The coated plates are thermally treated up to 600℃. The temperature-dependent anticorrosive properties of Co3O4 NPs are evaluated.

Hybridized nanocatalysts (AgNPs-Fe2O3) were prepared with silver nitrate and ferric chloride in the presence of sodium borohydride. The synthesized nanocatalyst was calcined, milled, and sieved for further applications. The nanocatalyst was characterized using Fourier transform infrared spectroscopy (FTIR) for the identification of functional moieties involved in the synthesis of the nanocatalyst. The vibrations of Fe and Ag were found at 566, 790 and 892 cm-1. The crystalline nature of the nanocatalyst was determined using X-ray diffraction (XRD) studies. The diffraction peaks for Ag and Fe can be seen at 2θ values of 30.42, 44.36, 62.45, 42.24 and 53.25. The morphology and elemental analysis of nanocatalysts were studied using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDAX). The particles are found to be spherical in shape. The signal for Ag and Fe can be found at 3.0 keV and 0.7, 6.3, 7.0 keV, respectively. The synthesized nanocatalyst was employed in the remediation of 2,4-dinitrophenol. The AgNPs-Fe2O3 nanocatalyst completely reduced (97%) the 2,4-dinitrophenol to 2,4-diaminophenol within 24 h.

Floriculture is a growing sector and represents an asset to the economy of most developing countries in Africa. This paper aims to access the existing knowledge gaps and how such gaps might be filled to develop the floriculture industry sustainably in Africa. Scientific information on the floriculture industry was searched on three online databases (ScienceDirect, Google Scholar African Journals Online and PubMed) to gather much reliable data on the last 30 years in Africa. Thus, 23 scientific publications distributed in eight African countries were considered and examined. East African countries are the most interested in the floriculture industry, with Kenya and Ethiopia as the leaders. There are about a hundred ornamental plant in Africa and they are dominated by exotic species that sold (50%) in northern countries. The cut flowers and foliage are mainly used to brighten up party days, insightful human well-being and the perfumery industry, as well as landscape plants, for hedging, game cover, slope stabilization, food, and aromatherapy. The most important challenges to tackle in floricultural production are related to climate change, pests, and pathogens attacks. Irrigated floricultural production, development and culture of resistant and adaptative varieties, and creation of home markets are recommended to ensure sustainable improvement of environmental quality, food security, and socio-economic aggregate for communities.

Liver disease has a global distribution and ranks as the twelfth leading cause of mortality. This cross-sectional study carried out between June and November 2021 aimed to assess the liver biochemical status of carpenters occupationally exposed to wood dust in Enugu metropolis South-east Nigeria. The Ethical Committee of the University of Nigeria Teaching Hospital in Enugu gave its approval. A total of one hundred and twenty-four (124) participants; sixty-two (62) carpenters (exposed) and sixty-two (62) age and sex-matched (males) control (unexposed) were recruited for this study. Study participants were chosen by simple random sampling. Spectrophotometric method was used to test participants’ blood samples for liver enzymes alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP). A statistically significant increase (p<0.05) was observed in the liver biochemical enzymes of the carpenters (exposed) in comparison to the controls (unexposed). The carpenters do not use any form of personal protective equipment (90.32%) or have a good knowledge of any occupational risk (83.87%) they are exposed to.  A statistically significant positive correlation (p<0.05) was observed between ALT, AST and ALP enzyme activity and the duration of exposure to wood dust (in years) of the exposed. This study suggests that occupational exposure to wood dust may cause metabolic changes in the Liver. Constant use of personal protective equipment when at work, personal hygiene and regular health check is recommended.
Information management and cultural evolution in Aboriginal Australia (In light of the cultural heterochrony hypothesis)
Authors: Steiner George F.
Published: November 2023

Following a recent re-evaluation of evidence from an archaeological site in SE Australia, the possibility of a 120 thousand years (ka) old human presence in the Fifth Continent has been suggested. However, the commonly accepted date for the peopling of Australia remains within the range of 50 - 65 ka. Even if the newly proposed date were halved, an uninterrupted 60 ka continuity in the same territory would raise a few questions regarding the transmission mechanisms that have enabled the retention of the massive amount of knowledge acquired during such an extended period, especially when considering the lack of demographic strength, which is believed to be a prerequisite for effective social learning. I argue that the emergence, developmental rate, and extent of Australian culture reflect an ‘additive’ evolutionary strategy centred on a ritually regulated feedback loop between the volume of information flow and the level of social elaboration. The model forwarded in this paper is at odds with current theoretical approaches to cultural evolution in which Aboriginal traditions are often portrayed as living examples of Pleistocene cross-cultural universals.
