Espace, Travail et numérique. Le cas du travail en flex office
Authors: Heddad Nadia
Published: October 2021

Cet article s’ancre dans le champ de l’ergonomie de l’activité. Il propose d’aborder la question spatiale dans les organisations de travail autour du modèle du flex office. Une première partie traite de la spécificité des espaces dédiés au travail. La question de la subordination du travail les distingue en effet clairement des autres lieux de la vie. Une deuxième partie propose une approche théorique de l’espace pour poser un cadre visant à saisir dans un même temps, la question de l’activité de travail et celle de l’espace. L’espace pensé pour la tâche se différencie de l’espace modelé et agi par l’activité de travail. Une troisième partie aborde la question du lien observé entre le digital et l’évolution des espaces dans l’immobilier des entreprises avec l’introduction du modèle du flex office dans le tertiaire. Une quatrième partie présente l’étude de cas et les méthodes utilisées dans le cadre d’un retour d’expérience. Une cinquième partie met l’accent sur les caractéristiques des espaces dans le modèle du flex office. D’un côté, elles questionnent la manière dont l’espace, conçu par les concepteurs, participe de la tâche et de l’autre, la manière dont l’activité de travail s’y déploie. Le travail se réalise dans une porosité spatio-temporelle dans et hors de l’entreprise. Ce faisant, l’activité de travail en flex office contribue à renforcer le développement du numérique, à la fois condition et résultante du travail en flex office. Enfin, une dernière partie ouvre sur la discussion et les perspectives du point de vue du travail
L’appropriation d’un open‑space au prisme de l’approche de l’acceptation située
Authors: Trisse Nathalie , Lagabrielle Christine
Published: October 2021

Cet article se propose d’utiliser l’approche de l’acceptation située (Bobillier Chaumon, 2016) issue de la clinique des usages pour tenter de comprendre le processus d’appropriation des espaces de travail. Initialement élaborée pour expliquer le processus d’acceptation des nouvelles technologies par les utilisateurs dans un environnement professionnel, cette approche est ici transposée à l’appropriation d’espaces de travail aménagés en open-space. L’étude exploratoire présentée repose sur 3 entretiens collectifs menés auprès d’un groupe de 10 managers de proximité au sein d’une grande collectivité territoriale. L’analyse des 4 dimensions constitutives de cette approche souligne que le processus d’appropriation des open-spaces est un processus multidimensionnel, dynamique, différencié et fortement contextualisé. Les résultats montrent également l’importance de la médiation de l’activité dans ce processus. Enfin, s’ils légitiment la co-construction en amont des projets d’aménagement des espaces de travail entre leurs concepteurs et leurs utilisateurs, ils présentent également les limites de la transposition de l’approche choisie à d’autres dispositifs que ceux pour laquelle elle a initialement été mobilisée.
Activités de formation des enseignants novices et trajectoire de satisfaction professionnelle : conceptualisation et illustration
Authors: Amathieu Jérôme , Chaliès Sébastien
Published: October 2021

Différents rapports institutionnels (Lachman, Nasse-Légeron) traitent de la question du bien-être des travailleurs. En leur sein, une relation est régulièrement établie entre la santé des enseignants et la nature des activités qu’ils mènent au sein des établissements scolaires. Du point de vue des théories de l’activité, ce consensus amène à une principale réserve. En assimilant la satisfaction professionnelle à un état psychologique stable et « a situé », ces études la désolidarise de l’activité effective des enseignants, activité nécessairement située en contexte de classe et par-là même constamment soumise à des circonstances situationnelles sans cesse renouvelées. En prenant appui sur quatre postulats empruntés à un programme de recherche mené en anthropologie culturaliste (Auteurs, 2017), cette étude a pour ambition d’aider au dépassement de cette réserve. Pour ce faire, elle propose successivement (i) une conceptualisation théorique originale permettant d’appréhender selon un point de vue qualitatif le couplage activité - satisfaction professionnelle, (ii) une démarche méthodologique permettant de rendre compte du caractère situé et dynamique de ce couplage et, enfin, (iii) une illustration et une discussion du caractère heuristique de ces propositions théoriques et méthodologiques à partir de la présentation de résultats empiriques extraits d’une étude de cas.
Identifier des routines interactionnelles dans le travail des éducateurs de l’enfance : le cas des arrivées des enfants dans les structures d’accueil
Authors: Zogmal Marianne , Filliettaz Laurent
Published: October 2021

Cette contribution s’intéresse aux routines interactionnelles qui structurent le travail des éducatrices et des éducateurs à l’occasion des temps d’accueils des enfants dans leur lieu d’accueil, au moment où ils arrivent dans l’espace éducatif accompagnés de leurs parents. Il vise à mieux comprendre comment se coordonnent les participants au moment de ces accueils et les ressources qu’ils mobilisent dans le cadre de cette coordination. Pour mettre en évidence des éléments récurrents et identifier des routines interactionnelles, la démarche adoptée cherche, plus généralement, à présenter et discuter des voies méthodologiques possibles. En continuité avec des travaux portant sur l’analyse interactionnelle, un dispositif empirique documente de manière méthodique des interactions verbales et non-verbales prenant place au moment des accueils et des départs des enfants et de leurs familles au sein de deux institutions de la petite enfance. Les temps d’accueil sont analysés, dans leur dimension à la fois temporelle et multimodale, au moyen d’une méthodologie qui se déploie par étapes. Des analyses portant sur des séries de situations contrastées et leurs caractéristiques sont complétées par des descriptions fines de cas singuliers. La discussion conclusive permet de revenir sur les ingrédients des routines d’interaction et de discuter leur rôle dans l’organisation du travail des professionnels de l’éducation de l’enfance.

Introduction. Les métaux précieux en Méditerranée médiévale
Authors: Bailly-Maître Marie-Christine
Published: October 2021

L’intérêt pour les métaux précieux en Méditerranée médiévale, en dehors de quelques travaux précurseurs, n’a réellement pris forme que depuis une trentaine d’années. Les niveaux de recherche sont très variables d’un pays à l’autre, tant dans leur organisation institutionnelle que dans leur finalité. Il est cependant évident que le bassin méditerranéen a été au cœur d’une intense activité de production et de circulation de métaux précieux, du nord vers le sud et inversement. Il était temps de faire un point sur les connaissances acquises, de reconsidérer les synthèses anciennes à la lumière des travaux récents et d’ouvrir sur la Méditerranée orientale trop peu prise en considération par une recherche centrée sur le sud de l’Europe (France, Espagne, Italie) et le nord de l’Afrique (Maroc et Tunisie).
Stimulated Axion-Like Bipolariton Generation in the Globular Photonic Crystal
Authors: Filatov Vladimir , Gorelik Vladimir , Pichkurenko Svetlana
Published: October 2021

Axion is the dark particle introduced to the quantum chromodynamics to solve the strong CP-problem. Because of its dark nature, there are many indirect evidences, but axion itself have not been registered till now. In the paper, we report the observation of dark axion-like particles formed by the polariton coupling in the resonant microcavity of a globular photonic crystal. To overcome the very small cross-section, we use the Bose-Einstein condensation of polaritons into the nearest-to-the-surface microcavity of an opal-like globular photonic crystal. This way, the synchronicity conditions are met and all polaritons have the same wavefunction to be coupled. Moreover, the giant density of states of a Bose-condensate makes polariton coupling not only allowed but stimulated. At the experiment, we observe “Light Shining through a Wall” Primakoff effect which proves dark particles. The additional spectral peak at the unitary polariton line of a maximal transparency of a crystal allows to differ bipolaritons from other particles. The results can be used not only to generate dark particles at a lab, but also to get a laboratory source of an optical-frequency gravitational waves.

Published: October 2021

The importance of local building materials has long been a significant point in all communities for thousands of years. It is well established that local materials form the backbone of construction in societies as they are the best response to the region's climate conditions. This study aims to determine the advantages and disadvantages of utilizing local materials in building construction. Specifically, it focuses on analyzing adobe bricks and examines whether it is suitable for the modern times. Saudi Arabia, a country that extensively relied on petroleum to flourish, is re-establishing itself by introducing the Saudi Vision 2030, a call of action to rely on available sustainable assets to develop the country. In this context, this research intends to demonstrate how promoting local materials' usage in construction would correspond with the vision's aims. This paper attempts to raise awareness about the local alternatives available and encourage utilizing them rather than the conventional building materials widely used, which are often not entirely suitable for Saudi Arabia's harsh desert climate. To further support this research, historical research proved that buildings built with local materials had withstood the test of time. This paper explores adobe as a case study because it is a unique building material in its style and sustainability. The intensive research results revealed that adobe bricks are a versatile material that gives different characteristics depending on the mixture of materials used to make them. On this basis, this paper examines the advantages and disadvantages of adobe bricks while proposing potential solutions to overcome the drawbacks.
Synthesis of Samarium Cobalt Oxide Nanosheets and Nanoflowers on Nickel Foam via Electrochemical Route
Authors: Buizon Lance Patrick M. , Marquez Menandro C.
Published: October 2021

Cobalt oxide (Co3O4) nanosheets were successfully synthesized and deposited onto the nickel foam substrate via electrochemical route. The chronoamperograms during the deposition revealed electrochemical activity resulting to the nucleation of the cobalt ions forming cobalt hydroxide and transformation to cobalt oxide. Energy dispersive xray (EDX) results elucidates the presence of samarium, cobalt and oxygen in the sample. The formation of nanosheets was confirmed by scanning electron microscopy. It was found that adding more samarium in the electrochemical bath changes the morphology of the final product from nanosheets to nanoflowers. The evolution of nanosheets to nanoflowers of the synthesized material could pave way for its potential application in the field of electrochemical energy storage devices and electrochemical sensors.
Deficiencies in the DNA Binding Protein ARID3a Alter Chromatin Structures Important for Early Human Erythropoiesis
Authors: Garton Joshua , Shankar Malini , Chapman Brittany , Rose Kira , Gaffney Patrick M , Webb Carol F
Published: October 2021

ARID3a is a DNA-binding protein important for normal hematopoiesis in mice and for in vitro lymphocyte development in human cultures. ARID3a knockout mice die in utero with defects in both early hematopoietic stem cell populations and erythropoiesis. Recent transcriptome analyses in human erythropoietic systems revealed increases in ARID3a transcripts implicating potential roles for ARID3a in human erythrocyte development. However, ARID3a transcript levels do not faithfully reflect protein levels in many cells, and the functions and requirements for ARID3a protein in those systems have not been explored. We used the erythroleukemic cell line K562 as a model to elucidate functions of ARID3a protein in early human erythropoiesis. ARID3a knockdown of hemin-stimulated K562 cells resulted in lack of fetal globin production and modifications in gene expression. Temporal RNA sequencing data link ARID3a expression with the important erythroid regulators Gata1, Gata2, and Klf1. Ablation of ARID3a using CRISPR-Cas9 further demonstrated it is required to maintain chromatin structures associated with erythropoietic differentiation potential. These data demonstrate that the ARID3a protein is required for early erythropoietic events and provide evidence for the requirement of ARID3a functions for proper maintenance of appropriate chromatin structures.
Sporadic Creutzfeldt-Jakob disease: Real-Time Quaking Induced Conversion (RT-QuIC) assay represents a major diagnostic advance
Authors: Cazzaniga Federico Angelo , Bistaffa Edoardo , De Luca Chiara Maria Giulia , Bufano Giuseppe , Indaco Antonio , Giaccone Giorgio , Moda Fabio
Published: October 2021

Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare and fatal neurodegenerative disorder with an incidence of 1.5 to 2 cases per million population/year. The disease is caused by a proteinaceous infectious agent, named prion (or PrPSc), which arises from the conformational conversion of the cellular prion protein (PrPC). Once formed, PrPSc interacts with the normally folded PrPC coercing it to undergo similar structural rearrangement. The disease is highly heterogeneous from a clinical and neuropathological point of view. The origin of this variability lies in the aberrant structures acquired by PrPSc. At least six different sCJD phenotypes have been described and each of them is thought to be caused by a peculiar PrPSc strain. Definitive sCJD diagnosis requires brain analysis with the aim of identifying intracerebral accumulation of PrPSc which currently represents the only reliable biomarker of the disease. Clinical diagnosis of sCJD is very challenging and is based on the combination of several clinical, instrumental and laboratory tests representing surrogate disease biomarkers. Thanks to the advent of the ultrasensitive Real-Time Quaking-Induced Conversion (RT-QuIC) assay, PrPSc was found in several peripheral tissues of sCJD patients, sometimes even before the clinical onset of the disease. This discovery represents an important step forward for the clinical diagnosis of sCJD. In this manuscript, we present an overview of the current applications and future perspectives of RT-QuIC in the field of sCJD diagnosis.

Authors: Eghbalian Fatemeh , Aqaie Rojin , Jiriaee Nasrin , Jenabi Ensiyeh
Published: October 2021

Introduction:

Hyperbilirubinemia is a common complication among neonates. The objective of this cross-sectional study was the prevalence of glucose 6-phosphate dehydrogenase (G6PD) deficiency among neonates with hyperbilirubinemia in the west of Iran.

Materials and Methods:

In this retrospective cross-sectional study, the records of neonates with hyperbilirubinemia who were hospitalised in Hamadan located in the west of Iran, from 2011 to 2016 were reviewed. After reviewing and studying each of the mentioned files, the necessary information was entered in the relevant checklists. Then, the neonates were divided into two groups, including the group with G6PD enzyme deficiency in the case study group and the G6PD enzyme-free group in the control study group. All statistical analyses were conducted in SPSS version 21 software and P < 0.05 was statistically considered significant.

Results:

A total of 1545 neonates with hyperbilirubinemia was reviewed. Among them, 40 neonates were in the case group and 1505 were in the control group. The prevalence of G6PD deficiency in the present study was 2.58% among neonates with hyperbilirubinemia which has a similar gender distribution. There were statistically significant differences between case and control groups based on total bilirubin, direct bilirubin, reticulocyte count, time of appearance of jaundice, duration of receiving phototherapy and hospitalisation (P < 0.05).

Conclusion:

We proposed that cord blood G6PD screening be conducted among neonates. This can be affected in identifying G6PD-deficient neonates who might require a longer hospital stay after birth, with monitoring of their serum bilirubin before and after discharge.

Authors: Dave Anuja Kashyapbhai , Dave Bela , Thakker Viral , Joshi Nancy , Katariya Mahendrakumar , Patel Harsh
Published: October 2021

Introduction:

Periodontal disease is a multifactorial disease and one of the most common chronic diseases of the oral cavity. Smoking has a long-term chronic effect on many important aspects of the inflammatory and immune responses. Tobacco smoke has been found to affect both cell-mediated immunity and humoral immunity. Oral smokeless tobacco consumption has been considered a major risk factor for oral cancer. Its role as a risk factor for periodontal disease is less well-documented when compared to that of the relationship between smoking and periodontal disease.

Materials and Methods:

One hundred and eighty participants willing to sign informed consent were selected randomly with no gender bias, and the purpose of the study was explained. The periodontal examination was conducted, and the oral hygiene index-simplified (OHI-S), community periodontal index (CPI) score and loss of attachment (LOA) score were recorded. The collected data were analysed using SPSS 20 software.

Results:

Sixty participants in each group were examined. OHI-S mean score in Group 1 was 1.77 ± 0.43, in Group 2, it was 1.70 ± 0.65 and in Group 3, it was 1.73 ± 0.55. The mean value of CPI was 3.32 ± 0.47 in Group 1, 2.17 ± 0.46 in Group 2 and 2.67 ± 0.54 in Group 3. In comparison, the mean value of CPI-LOA was 1.35 ± 0.48 in Group 1, 1.65 ± 0.5 in Group 2 and 1.18 ± 0.65 in Group 3.

Conclusion:

The present survey concluded that tobacco consumption in both the forms caused poor periodontal status, with smokers having more pocket depth than tobacco chewers and non-tobacco users and tobacco chewers having more LOA than smokers and non-tobacco users.

Published: October 2021

Introduction:

This study aimed to test the reliability of the index of treatment need by newly trained orthodontic residents.

Materials and Methods:

A total of 100 patients were assessed by the panel of four consultant orthodontists using the index of orthodontic treatment need (IOTN) index, and the agreed category was set as the 'gold standard'. Four residents of the department in the initial stages of formal orthodontic training and lacking the knowledge of using the IOTN index were trained to score the treatment need according to the IOTN index. All four residents were then asked to score the 100 sets of models using both the indexes of IOTN.

Results:

Kappa scores for inter-rater agreement with the expert panel for the major categories (1–4) demonstrated moderate agreement (kappa: 0.59–0.5623) for all raters. The percentage agreement ranged from 84.03% to 88.10% in all cases. Intra-rater agreement for the major categories was fair to moderate (kappa: 0.53–0.80).

Conclusions:

The IOTN index is a reliable index to be used for determining the priority of treatment needs in orthodontic treatment. The clarity and simplicity make the index easy to learn and apply with minimal training. The simplicity of the IOTN index makes it easy to learn and apply by novices.

Published: October 2021

The impact of coronavirus disease 2019 (COVID-19) pandemic has raised health concerns worldwide. Medical and allied health professional schools are seeking ways to alleviate stress and improve the quality of life among students. The effects of yoga have proven to be successful against stress. The review aimed to examine the psychophysiological effects of yoga on stress management among medical and allied health professional students during COVID-19 pandemic. The authors reviewed existing literature and official documents, which mostly focussed on the effect of yoga among medical and health professional students. Mental stress among these students is known to be higher than that of the general population. Sudden changes due to the pandemic are likely to have a significant impact on these students. Uncertainties concerning teaching, learning and assessment generate stress and anxiety, and social distancing further contributes to loneliness. Yoga has gained recognition not only in improving mental health and quality of life, but it also helps in improving respiratory and immune health. Although many published studies examined the psychophysiological effects of yoga among health professional students; only a few medical and allied health professional schools have incorporated yoga into an integrated curriculum for a holistic approach. In response to the COVID-19 crisis, the use of yoga for stress reduction and immune modulation should be considered as a complement to other treatments. There is a need to integrate yoga into medical and health science curricula to prepare physically fit and mentally sound prospective healthcare professionals.

Introduction:

The loss of alveolar bone is one of the important indicators of periodontitis. There is a widespread use of panoramic radiographs for the detection of bone loss due to periodontitis. The present study is aimed to evaluate the severity and prevalence of alveolar bone loss at mandibular first molar sites on randomly selected 250 orthopantomograms.

Materials and Methods:

The alveolar bone level was assessed by direct measurements from the cemento-enamel junction to the crest of alveolar bone at the mandibular first molar region at the mesial and distal surface with a Hu-Friedy University of North Carolina probe-15 Probe. Bone loss was assessed based on gender and age.

Results:

The results indicated that the bone loss was statistically higher in the mandibular molar region on the distal surface than the mesial surface. The bone loss notably increased with age.

Conclusion:

In conclusion, the study is in accordance with the finding that radiographic bone loss can be used as an important tool to identify patients susceptible to periodontitis.
Impact of Lifestyle Change Plus Dental Care Programme on Stress Levels and Periodontal Status in Chronic Periodontitis Patients
Authors: Duseja Shilpa , Parikh Hiral
Published: October 2021

Introduction:

Periodontitis is a polymicrobial chronic disease modified by numerous factors, with stress and unhealthy lifestyles being associated with the progression of the disease. It is believed that cognitive-behavioural approaches can improve stress and lifestyle patterns which may subsequently improve oral hygiene-related behaviours.

Materials and Methods

: Hundred systemically healthy patients participated in the study. Patients with chronic periodontitis, stress (Social Readjustment Rating scale) and with unhealthy lifestyles (Abel's criteria) were selected for the study. The selected patients in the test group (n = 50) were provided with Individual lifestyle counselling and oral education programme along with non-surgical periodontal therapy, while the patients in the control group (n = 50) were provided with non-surgical periodontal therapy. Plaque index (PI), modified gingival index (GI) and probing depth were recorded at baseline and 3 months. The self-efficacy scale for self-care (SESS) was also recorded at baseline and 3 months. Means of all parameters were collected and subjected to Student's t-test.

Results:

Statistically significant (P ≤ 0.05) reductions were observed in both test and control group for PI, modified GI and probing depth. The SESS showed statistically significant improvement (P ≤ 0.01) in the test group as compared to the control group.

Conclusion:

Self-efficacy is related to numerous health-related practices such as diet and health-promoting lifestyle, and smoking cessation. The approaches applying the social cognition model are useful for the improvement of periodontal status and should be made part of regular treatment and maintenance regimens.

Published: October 2021

Solid-organ transplant increases the physical and mental well-being of women suffering from chronic kidney diseases. It also improves the menstrual and reproductive function of the transplant recipient, putting a woman at risk of unplanned pregnancy. Various contraceptive options are available to such women. According to the World Health Organization Medical Eligibility Criteria, almost all contraceptive methods belong to Category 2 for uncomplicated post-transplant recipients. For complicated renal-transplant patients, intra-uterine devices are Category 3/2, and combined hormonal contraceptives are Category 4. It is of paramount importance to discuss the pros and cons of each method, and this counselling should be included routinely before undergoing transplant surgery.

Published: October 2021

Introduction:

Oral diseases and traumatic injuries are serious public health problems, especially when talking about children. Mutilation of the function and reduced quality of life has an influence on individuals and communities. The most widespread oral disease in developing countries has been found to be dental caries. The maintenance of healthy permanent molars is very important. DMFT and PUFA index can be used to determine the caries status and severity in untreated carious teeth of an individual.

Materials and Methods:

This was a cross-sectional descriptive survey that included 1380 children between the age group 8–10 years from public and private schools of Vadodara, Gujarat. The study population was divided based on their socioeconomic status as upper, middle and low according to the Kuppuswamy scale. The study was conducted 2 days per week for 6 months to examine the participants. Dental caries was assessed using DMFT index, and the severity of caries was evaluated by PUFA index for permanent first molars.

Results:

The prevalence of first permanent molar caries in Vadodara city was 55.38%; 747 out of 1380 children of 8–10 years of age were affected with caries evaluated using DMFT index. The severity of first permanent molar caries (PUFA index) was found to be 56.22%. That is, 420 out of 747 children had more severe first permanent molar caries.

Conclusion:

Caries prevalence and severity increase with age. PUFA index is an effective index in evaluating the clinical sequel of untreated carious teeth and helps better treatment plans for a socially deprived group of society.

Published: October 2021

Introduction:

Risk factors such as dietary habits and physical inactivity for non-communicable diseases are common and preventable. Thus the reduction in risk factors forms the epicentre of the management of non-communicable diseases. This study was carried out with an objective to compare dietary habits and sedentary lifestyle among the female health Sciences College and non-health college students in a Saudi Arabia University.

Materials and Methods:

The comparative cross-sectional study was carried out among 700 students belonging to both health sciences and non-health colleges at Princess Nourah Bint Abdulrahman University, Riyadh, Saudi Arabia, from October 2019 to December 2019. A self-administrated questionnaire regarding their diet habits and physical activity was shared with the participants. The distributive statistics were analysed and discussed.

Results:

Among the total 700 students, 363 students were from the college of health sciences, and 337 were from Non-health College students. The majority of students did not have the recommended meals, with most of them eating only two meals in a day, 51.2% in health sciences college students and 48.1% in non-health college students. About 29.9% of the college students were physically inactive, wherein 28.4% were among the college of health sciences, and 31.5% were non-health, college students, respectively. The difference in the two groups regarding primary source of daily food, the quantity of daily fluid intake, number of hours of sedentary life and the activity after food intake was statistically significant (P ≤ 0.05).

Conclusion:

This study showed that the eating and sedentary lifestyle habits in the two groups were almost the same, but the difference between the type of food, the quantity of fluid intake and time for physical activity did have significance statistically. These findings have to be further studied to understand the impact on health.

Authors: Joshi Ravi Maheshchandra , Shah Dipti S , Vaishnav Kalpesh , Shah Komal , Agnihotri Radhika
Published: October 2021

Restricted mouth opening (microstomia) can be defined as a reduction in the circumference of the oral cavity, although the intraoral structures may be of normal size. It is observed that the size of the oral opening decreases, the difficulty increases in required dental treatment. Prosthetic rehabilitation of microstomia patients due to oral sub-mucous fibrosis (OSMF) presents difficulties at all stages, right from preliminary impressions to insertion of prostheses, as the maximal oral opening is smaller than the size of a removal intra-oral prosthesis. To rehabilitate this type of patient successfully, the methods and designs incorporated in the fabrication of prosthesis have to be modified to achieve favourable mastication, retention and aesthetics. This article describes modified primary impression procedure without using tray and other techniques used to fabricate maxillary and mandibular custom sectional trays, sectional denture bases and removable sectional complete dentures for completely edentulous patient with limited oral opening caused by OSMF. Fabricating the sectional denture allows the patient to insert and remove the denture with ease.

Authors: Raval Yesha Haresh , Shah Monali Amit , Dave Rahul Deepak , Debnath Aastha Vishwanath
Published: October 2021

Introduction:

Blood clot or platelet concentrates have been used as a scaffold for regeneration of lost tissues. The most difficult case to date is the restoration of missing interdental papillae in the anterior maxillary area. Hence, the aim of the study is to evaluate the efficacy of the use of platelet-rich fibrin (PRF) membrane in the treatment of black triangles and regeneration of interdental papilla.

Materials and Methods:

A non-randomised, single-arm study was carried out. Each participant had undergone an initial periodontal diagnosis, including oral hygiene instructions, plaque control and scaling and root planing. All clinical recordings were recorded immediately before surgery (baseline), 1 week, 4-week and after 12-week intervals following periodontal surgery. The measurements recorded were triangle height (TH), triangle width (TW), Papilla Presence Index (PPI) and percentage fill. The split-thickness flap was carried via the semilunar incision, creating a pouch. PRF was obtained using a standard protocol, which was inserted into the pouch allowing interdental papillae to be filled. The periodontal dressing was given for 7 days. The observations were recorded after 1 week, 49 weeks and 12 weeks of surgery. For descriptive analysis, mean ± standard deviation SD at baseline, 1 week, 4 weeks and 12 weeks was calculated, and for non-parametric test, Friedman and Chi-square tests were used.

Results:

Clinical parameters such as TH, TW and PPI (mm) was 3.96, 3.86 and 3.82 at baseline which after 12 weeks got reduced to 1.36, 1.68 and 1.58, respectively. This reduction in TH, TW and PPI(mm) was statistically significant (P< 0.001). Percentage fill in black triangle area was about 85% after 12-week follow-up.

Conclusion:

PRF membrane is effective in treating black triangles and regeneration of interdental papilla and can be used successfully.

Published: October 2021

Background:

The coronavirus disease 2019 (COVID-19) presents various phenotypes from asymptomatic involvement to death. Disseminated intravascular coagulopathy (DIC) is among the poor prognostic complications frequently observed in critical illness. To improve mortality, a timely diagnosis of DIC is essential. The International Society on Thrombosis and Hemostasis (ISTH) introduced a scoring system to detect overt DIC (score ≥5) and another category called sepsis-induced coagulopathy (SIC) to identify the initial stages of DIC (score ≥4). This study aimed to determine whether clinicians used these scoring systems while assessing COVID-19 patients and the role of relevant biomarkers in disease severity and outcome.

Materials and Methods:

An exhaustive search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses, using Medline, Embase, Cochrane, CINAHL, and PubMed until August 2020. Studies considering disease severity or outcome with at least two relevant biomarkers were included. For all studies, the definite, maximum, and minimum ISTH/SIC scores were calculated.

Results:

A total of 37 papers and 12,463 cases were reviewed. Studies considering ISTH/SIC criteria to detect DIC suggested a higher rate of ISTH ≥5 and SIC ≥4 in severe cases and nonsurvivors compared with nonsevere cases and survivors. The calculated ISTH scores were dominantly higher in severe infections and nonsurvivors. Elevated D-dimer was the most consistent abnormality on admission.

Conclusion:

Higher ISTH and SIC scores positively correlate with disease severity and death. In addition, more patients with severe disease and nonsurvivors met the ISTH and SIC scores for DIC. Given the high prevalence of coagulopathy in COVID-19 infection, dynamic monitoring of relevant biomarkers in the form of ISTH and SIC scoring systems is of great importance to timely detect DIC in suspicious patients.

Background:

Exercise can reduce hepcidin, tumor necrosis factor (TNF)-α, and interleukin (IL)-6 and improve the iron status, but the intensity of exercises is very important. This study will compare the effect of resistance training (RT) intensity on hepcidin levels, iron status, and inflammatory markers in overweight/obese girls with and without iron stores deficient.

Materials and Methods:

In this quasi-experimental study, 40 students of the University of Isfahan (18–22-year old, with 35 > body mass index [BMI] ≥25) voluntarily participated in the study. Participants were divided into two groups with 20 participants, based on serum ferritin (>30 ng/ml or ≤30 ng/ml). Participants in each group were randomly and equally assigned to one of the moderate or high-intensity training groups. RT was performed 8 weeks, 4 days a week, and each session for 1 h, with an elastic band. The iron levels, hepcidin, total iron-binding capacity, ferritin, hemoglobin, TNF-α, and IL-6 before and after intervention were collected with the blood samples. Two-way analysis of variance was used to assess the impact of exercise and ferritin level and their interaction, and the paired test was utilized for test changes from baseline.

Results:

There are no significant interactions between ferritin levels and exercise intensity for the main outcomes (all P > 0.05). The significant impact of the mode of exercise was observed in TNF-α (P < 0.05), and a significant difference between low and high levels of ferritin was observed in hepcidin (P = 0.002). Besides, in all four groups, significant decreases were observed in BMI (28.00 ± 3.00 to 27.00 ± 3.00), hepcidin (1234.02 ± 467.00 to 962.06 ± 254.00), and TNF-α (223.00 ± 99.00 to 174.00 ± 77.00) compared to the baseline measurements (all P < 0.05).

Conclusion:

Basal ferritin levels appear to be effective on hepcidin levels, TNF-α, and IL-6 after the intervention. RT with two different intense can reduce BMI, hepcidin, ferritin, and TNF-α in all groups. It seems that performing RT reduces inflammation and hepcidin in obese/overweight participants with different iron stores.

Human strongyloidiasis is one of the neglected tropical diseases caused by infection with soil-transmitted helminth Strongyloides stercoralis. Conventional stool examination, a method commonly used for diagnosis of S. stercoralis, has low sensitivity, especially in the case of light infections. Herein, we developed the droplet digital polymerase chain reaction (ddPCR) assay to detect S. stercoralis larvae in stool and compared its performance with real-time PCR and stool examination techniques (formalin ethyl-acetate concentration technique [FECT] and agar plate culture [APC]). The ddPCR results showed 98% sensitivity and 90% specificity, and real-time PCR showed 82% sensitivity and 76.7% specificity when compared with the microscopic methods. Moreover, ddPCR could detect a single S. stercoralis larva in feces, and cross-reactions with other parasites were not observed. In conclusion, a novel ddPCR method exhibited high sensitivity and specificity for detection of S. stercoralis in stool samples. This technique may help to improve diagnosis, particularly in cases with light infection. In addition, ddPCR technique might be useful for screening patients before starting immunosuppressive drug therapy, and follow-up after treatment of strongyloidiasis.

Memes About Socially Significant Events as an Instrument for Social Consolidation

The meme is the main genre form which enlarges their consideration and semantics. Being a genre of contemporary folklore, the meme provides understanding about the language world view of representatives of a certain mentality; the article shows it with the examples of consideration stages for the current key word Coronavirus in the Russian language usage. The development of modern media discourse is processing in such a way that the current key words, which appeared in media due to the political agenda, continue to live in the social networks. The language exists as a response to current social events, and the topical vocabulary of the current moment is not an exception in this sense. The article presents the potential of key words consideration as the basis of social interaction in the process of consolidation and identification.

Analiza memu – jednego z gatunków współczesnego folkloru – pomaga w zrozumieniu językowego obrazu świata nosicieli narodowej mentalności. Pokazujemy to na przykładzie etapów rozwoju w rosyjskim uzusie językowym znaczenia leksemu koronawirus – słowa klucza chwili obecnej. Dla współczesnego dyskursu medialnego charakterystyczny jest obieg tzw. słów kluczy chwili obecnej. Pojawiwszy się w mediach tradycyjnych ze względu na wydarzenia polityczne, kontynuują swoje życie w mediach społecznościowych. Ogląd współczesnego słownictwa chwili obecnej pokazuje, że język reaguje na przemiany zachodzące w społeczeństwie. Nasze ustalenia pokazują potencjał myślenia o słowach kluczach jako o podstawie interakcji społecznej w procesie konsolidacji i solidaryzacji.

Rapidly increasing COVID-19 or SARS-CoV-2 in whole world caused a tremendous pressure on existing diagnostic setup to give accurate diagnosis on time by gold standard RT-PCR technique forcing scientist to think beyond RT-PCR which ultimately ended with invent of Rapid antigen test which can give about 100% specific and rapid result but may miss many case due to low sensitivity.
So we wanted to evaluate the Rapid antigen test against RT-PCR for its diagnostic accuracy. We followed standard procedure for sample collection, Rapid antigen test and RT-PCR test.
In about one and half month span we collected 554 antigen negative samples in our hospital. About 13% sample (74/554) turned out as positive by RT-PCR test. About 40 % (30/74) positive samples had low Ct value (<25) indicating higher viral load present in those patients. Above findings indicate that only antigen test will miss a significant portion of positive cases with higher viral load which may complicate the pandemic by unknowingly spreading the virus within the society. So we should try to improve our infrastructure to carry out more RTPCR test so we can detect more cases to identify and isolate them from others to prevent or slowdown the transmission chain.

En el Perú, según los reportes históricos, la infraestructura vial no constituye un motivo de accidentes de tránsito; a pesar de que, según el estado del arte, los accidentes de tránsito se encuentran entre los diez primeros motivos de accidentes mortales a nivel mundial, hecho que es aún más visible en los países subdesarrollados. Los estudios sobre relieves montañosos (realidad de los países andinos) y para vehículos de carga son escasos. Por esta razón, se tomó como unidad de análisis una vía principal correspondiente a la red vial nacional, el objetivo fue establecer el nivel de consistencia de las vías de estudio y su incidencia en los accidentes de tránsito. Para ello, se establecieron los tramos críticos y su correspondencia con los accidentes de tráfico; se incorporaron al análisis tres tipos de vehículos (ligeros, de pasajeros y de carga); se utilizó la metodología de análisis de consistencia, en su modalidad de velocidad de operación para establecer los tramos críticos; se analizó la carretera bajo el criterio local y el criterio continuo.  Los resultados muestran que existen tramos inconsistentes; el criterio local explica mejor la inconsistencia de la unidad de análisis respecto al criterio continuo. Con la regresión de Poisson, el modelo integral es significativo; las variables independientes optimizan conjuntamente el modelo.

 

 

In Peru, according to historical reports, road infrastructure does not constitute a reason for traffic accidents; despite the fact that, according to the state of the art, traffic accidents are among the top ten reasons for fatal accidents worldwide, a fact that is even more visible in underdeveloped countries. Studies on mountainous reliefs (reality of the Andean countries) and for cargo vehicles are scarce. For this reason, a main road corresponding to the national road network was taken as the unit of analysis, the objective was to establish the level of consistency of the study roads and their incidence in traffic accidents. To this end, the critical sections and their correspondence with traffic accidents were established; three types of vehicles (light, passenger and cargo) were incorporated into the analysis; the consistency analysis methodology was used, in its operating speed modality to establish the critical sections; the road was analyzed under the local criterion and the continuous criterion.  The results show that there are inconsistent sections; the local criterion explains better the inconsistency of the unit of analysis with respect to the continuous criterion. With Poisson regression, the integral model is significant; the independent variables jointly optimize the model.
