Tous contributifs ? Vers une société multiactive !
Authors: Fusulier Bernard , Nicole-Drancourt Chantal
Published: February 2022

La notion de société multiactive renvoie à un régime d’activité de type nouveau. L’ancien est celui dans lequel nous vivons encore aujourd’hui : c’est un régime qui se caractérise par l’adossement de la définition de l’activité sur un et un seul signifiant : l’emploi. Ce référentiel d’organisation du régime d’activité a permis de construire la société salariale, mais il montre aujourd’hui ses limites dans un contexte structurel et culturel en changement profond. Face à la nécessité d’une réelle disruption, les auteurs proposent, à partir d’une approche genre, un scénario alternatif de l’organisation sociétale : la société multiactive, qui s’enracine dans des pratiques individuelles et institutionnelles innovantes déjà à l’œuvre. Il s’agit alors de repenser le logiciel social en vue de reconnaître la contribution de chacun.e aux activités productrices à la fois de biens communs et de bien-être, sans qu’aucune ne soit distribuée en fonction du genre.
Le rôle de la médiation culturelle dans l’apprentissage de l’habitant
Authors: Jojczyk Joanne
Published: February 2022

Cet article propose d’étudier l’activité de médiation au sein de projets participatifs et culturels. Nous envisageons l’activité de médiation comme une activité interactionnelle menant à des moments de construction de sens en groupe. Ces moments d’échanges sont analysés dans une approche processuelle mettant en lumière la constitution de productions à la fois matérielles et symboliques. Pour étudier ces productions, nous avons suivi un projet participatif lié au label de Capitale européenne de la Culture, Mons 2015. À travers ce cas, nous montrons comment l’apprentissage se crée au sein du collectif durant l’activité de la médiation et se traduit matériellement durant l’événement culturel.
L’intervention sociale réinventée face à la consommation d’héroïne
Authors: Wagener Martin
Published: February 2022

L’article propose de reconstruire l’évolution historique des modes d’intervention des travailleurs sociaux par rapport à l’arrivée massive de l’héroïne dans les années 1980, en se basant sur une approche comparative entre les villes de Liège et Aix-la-Chapelle. L’article reconstruit comment les acteurs de terrain, les politiques, l’appareil juridique et celui lié à la santé publique se sont adaptés à une consommation de drogues « dures », à travers des modes de coopération créés au sein de différents dispositifs qui lient les aspects d’aide à la personne et d’intervention sanitaire avec les aspects répressifs. En même temps que ces services se spécialisent, s’adaptent et élaborent leurs manières de travailler en réseau, se dégage pour eux l’enjeu de réinventer partiellement leurs pratiques, d’adapter leurs formations de base, afin d’être en phase avec des modes de consommation et des parcours de vie changeants.
L’espace temporel du salariat : une lecture articulée et qualitative à partir de l’enquête « Parlons Travail »
Authors: Viera Giraldo Valerya
Published: February 2022

1 2 L’articulation des temps sociaux est surtout approchée par la notion de « conciliation travail-famille », en réduisant parfois les enjeux à des stratégies individuelles optimisables. À l’inverse, cet article se propose d’aborder la question depuis une perspective macrosociale, afin de saisir les temporalités sociales dans leur complexité en employant une lecture en miroir des temporalités de travail salarié, et d’analyser leur articulation avec le vécu hors emploi. À l’appui d’une analyse géométrique des données de l’enquête Parlons Travail , nous présentons comment, en fonction de la marge de manœuvre temporelle et de l’intensité horaire, les configurations d’articulation varient et comment elles influencent le vécu hors emploi ; et cela notamment en jouant un rôle dans la santé des travailleurs, montrant ainsi qu’il ne s’agit pas tout à fait d’un « conflit individuel » mais d’une problématique sociale, de laquelle découlent non seulement des inégalités de genre et de classe, mais aussi des conséquences jusqu’à présent plus invisibles et qui transforment les conditions de vie dans la sphère privée.
Un pôle de psychiatrie citoyenne centré sur une offre ambulatoire
Authors: Defromont Laurent , Brière Jean-Luc
Published: February 2022

Le secteur 59G21 comprend six communes de la banlieue Est de Lille regroupant 88 000 habitants (Villes de Ronchin, Faches, Thumesnil, Lesquin, Hellemmes, Mons-en-Barœul, Lezennes). Il est rattaché à l’Etablissement Public de Santé Mentale (EPSM) Lille-Métropole situé à Armentières. Il fonctionne avec seulement 10 lits d’hospitalisation implantés sur le site du Centre Hospitalier Régional Universitaire (CHRU) de Lille, à proximité du lieu de vie des personnes suivies. L’équipe du secteur a depuis des années développé des pratiques fondées sur les soins dans la cité, un fort partenariat avec les communes et les acteurs sociaux et médicaux, l’inclusion sociale et le rétablissement. Il s’agit d’un modèle reproductible de psychiatrie ambulatoire et communautaire qui a été au bout de la logique du secteur et qui nécessiterait d’être mieux connu et enseigné.
Le management stratégique en Afrique : vers une réflexion autonome
Authors: Hafsi Taïeb
Published: February 2022

Cet article décrit l’expérience de développement des connaissances en management/stratégie qui a eu lieu aux États-Unis, en particulier pour répondre à la crise générée par la grande dépression de 1929, et qui a mené au développement de Harvard Business School (HBS). Les expériences Hawthorne et les réflexions sur la direction des entreprises qui ont pris place à Cambridge, Massachussetts, ont généré des résultats et une démarche de développement de la connaissance qui ont marqué le pays et le monde. Cette expérience est ensuite utilisée comme référence pour réfléchir aux besoins en matière de développement des connaissances et d’une pensée stratégique autonome en Afrique. Une démarche de recherche clinique et la description de situations exemplaires sous la forme de cas peuvent être aussi fécondes qu’au Massachussetts et à HBS. Le courage des élites et leur capacité à se parler à travers une recherche sur les processus concrets du développement seraient les conditions qui donneraient vie à l’initiative entreprise par la RISO dans ce numéro.

Authors: Perot Romain , Bergot Cécile , Silliau Dominique , Gourevitch Raphaël , Pham-Scottez Alexandra
Published: February 2022

Contexte : les infirmiers se retrouvent régulièrement confrontés à des personnes suicidaires. Leur implication est essentielle dans le dépistage et la prévention du risque suicidaire. Objectifs : au travers d’une revue de littérature, nous avons souhaité mettre en évidence le rôle de l’infirmier en pratique avancée par la conduite de formations spécifiques à l’amélioration des compétences infirmières dans la prise en charge des personnes ayant des idées suicidaires. Méthode : notre revue de la littérature a été effectuée selon les critères de recommandation PRISMA à partir de plusieurs bases de données. Résultats : celle-ci montre une amélioration dans la prise de confiance, dans les attitudes et les aptitudes infirmières à évaluer le risque suicidaire. Cependant, aucun changement des pratiques sur le long terme n’est démontré. Discussion : en France, un programme national de formation à la prévention du risque suicidaire est décliné sur le plan régional par les Agences régionales de santé. En parallèle, depuis 2019, la mention Psychiatrie et Santé Mentale est ajoutée au programme de formation des infirmiers en pratique avancée. Conclusion : l’infirmier en pratique avancée est un acteur central pour accompagner les équipes vers l’augmentation de leurs compétences, notamment dans la conduite de formations spécifiques.
Du modèle médical vers un modèle social de l’autonomie des personnes atteintes de mucoviscidose. Une étude sociologique du point de vue des acteurs professionnels et associatifs
Authors: Issanchou Damien , Ferez Sylvain , Silvestri Laura
Published: February 2022

L’autonomie du patient est une notion équivoque qui renvoie à plusieurs figures entremêlées. Qu’est-ce qui est attendu du jeune atteint de mucoviscidose dans les discours des acteurs (professionnels et associatifs) engagés à ses côtés ? Dans le cadre de cette contribution en sociologie, nous montrons les limites d’un modèle médical de l’autonomie, qui ne permet pas de penser toute une série de micro-ajustements des pratiques des personnes vivant avec cette maladie. L’analyse s’appuie, d’une part, sur les publications des associations nationales de lutte contre la mucoviscidose et, d’autre part, sur des entretiens semi-directifs avec des professionnels engagés auprès des malades. Elle montre que l’autonomie n’est pas uniquement pensée par les professionnels qui les suivent à l’aune d’un modèle de gestion individuelle centré sur les compétences médicales et les ressources personnelles du patient, mais aussi comme le résultat de facteurs environnementaux. Elle révèle une figure de l’autonomie innovante dans le champ de la santé, en grande partie portée par les infirmières coordinatrices dans le cadre d’un accompagnement médical spécialisé et renforcé. Cet accompagnement permet l’élaboration d’une connaissance clinique fine sur les situations vécues par leurs patients.
Promotion de la santé en psychiatrie et santé mentale : l’exemple du syndrome métabolique et des pratiques infirmières
Authors: Sonethavy Malasi , Morvillers Jean-Manuel
Published: February 2022

Introduction : l’espérance de vie chez les patients en psychiatrie est réduite de 15 à 20 ans, du fait de comorbidités et de leur mode de vie. Le syndrome métabolique, aussi effet secondaire des antipsychotiques, est un facteur aggravant de ce phénomène, c’est pourquoi la promotion de la santé est indispensable. L’objectif de l’étude est de décrire les connaissances, attitudes et pratiques infirmières en psychiatrie vis-à-vis du syndrome métabolique, avec pour cadre de référence le modèle de promotion de la santé de N. Pender. Méthodologie : une étude descriptive multicentrique à partir d’une enquête « connaissance attitude pratique » a été menée dans 16 services psychiatriques d’Ile-de-France. Soixante-dix infirmières ont été interrogées via des questionnaires en ligne. Résultats : les résultats montrent des connaissances partielles. Un écart existe entre les attitudes et les pratiques infirmières. Leurs actions relèvent principalement du conseil. Le type de savoirs infirmiers est abordé, ainsi que la nécessité d’une réflexion sur la relation infirmière-patient. Les interventions infirmières méritent d’être approfondies afin de mieux prendre en charge le syndrome métabolique. Conclusion : des actions de formation sont nécessaires pour mener de manière plus efficace des actions de prévention et de promotion de la santé.
Ocular Neuromyotonia in Children and Adolescents Following Radiation Treatment of Pediatric Brain Tumors
Authors: Richardson Cody , Smith Casey , Merchant Thomas , Khan Raja , Hoehn Mary Ellen
Published: February 2022

Purpose:

To report five cases of ocular neuromyotonia in children and adolescents following radiation therapy for a variety of pediatric brain tumors. Notably, three cases occurred in children younger than 11 years.

Methods:

Case series of five patients with ocular neuromyotonia following proton beam therapy or conventional radiation.

Results:

Five cases of ocular neuromyotonia were identified following radiation treatment of various pediatric brain tumors. Onset ranged from 5 to 142 months after radiation treatment. The abducens nerve/lateral rectus muscle was affected in three patients, and the trochlear nerve/superior oblique muscle was affected in two patients. Ages at symptom presentation were 4 years (intermittent head tilt), 9 years (intermittent blurry vision and head tilt), 10 years (intermittent blurry vision progressing to intermittent diplopia), 15 years (intermittent diplopia), and 17 years (intermittent diplopia). One patient improved with gabapentin. Two patients experienced spontaneous resolution. One patient died due to meta-static disease, and one patient has planned follow-up.

Conclusions:

Ocular neuromyotonia occurs most commonly following radiation to the brain and skull base. Clinicians need to be aware that ocular neuromyotonia presents differently in children (who may not report diplopia) than in adults or adolescents (who typically report diplopia). Two children in this series never reported diplopia, only intermittent head tilt and blurry vision. Ocular neuromyotonia requires a high index of suspicion to diagnose, especially in children. Membrane stabilizers can be used effectively, but observation may be a valid option in children because spontaneous resolution was seen.

Authors: Suzuki Hiroko , Hikoya Akiko , Inagaki Risako , Haseoka Takashi , Arai Shinji , Takagi Yuuri , Hotta Yoshihiro , Sato Miho
Published: February 2022

Purpose:

To compare conjunctival-scleral thickness measured with anterior segment optical coherence tomography before and after medial rectus muscle resection and plication for exotropia.

Methods:

In this prospective observational study, patients with exotropia aged 5 years and older who underwent medial rectus muscle resection or plication through limbal incision of the conjunctiva between April 2016 and June 2018 were enrolled. Conjunctivalscleral thickness was measured with anterior segment optical coherence tomography before and 3 and 6 months after surgery at 1.5 mm (limbus), 4 mm (insertion), and 5.5 mm (tendon) posterior to the scleral spur. One examiner made measurements twice blinded for the initial data. Conjunctival-scleral thickness was compared between groups using the Mann-Whitney
U
test.

Results:

Twenty participants were divided into two groups: resection (n = 11) and plication (n = 9). The respective conjunctival-scleral thicknesses before and 3 and 6 months after surgery in the resection group were as follows: 0.76, 0.90, and 0.86 mm at the limbus; 0.86, 1.18, and 1.12 mm at the insertion; and 1.04, 1.41, and 1.33 mm at the tendon. Corresponding values in the plication group were as follows: 0.74, 0.87, and 0.81 mm at the limbus; 0.84, 1.16, and 1.08 mm at the insertion; and 1.00, 1.39, and 1.27 mm at the tendon. No between-group differences were observed at any location or time.

Conclusions:

No differences in conjunctival-scleral thickness were observed between the resection and plication groups before surgery or at 3 months and 6 months postoperatively.

Comparison of Unilateral Versus Bilateral Lateral Rectus Recession for Small Angle Intermittent Exotropia: Outcomes and Surgical Dose-Responses
Authors: Lee Ming-Han Hugo , Smith David R. , Kraft Stephen P. , Wan Michael J.
Published: February 2022

Purpose:

To compare the surgical outcomes of unilateral lateral rectus recession to bilateral lateral rectus recession for small angle intermittent exotropia.

Methods:

This was a retrospective cohort study of pediatric patients with an intermittent exotropia between 16 and 20 prism diopters (PD) who underwent unilateral lateral rectus recession or bilateral lateral rectus recession at a single tertiary care pediatric hospital. The primary outcome was success (exotropia < 10 PD of esotropia < 5 PD, no decrease in stereopsis > 0.6 log arcsec, and no reoperation) at 12 months postoperatively. Secondary outcomes included survival analysis of time to surgical failure, surgical dose-response, and improvement in central fusion or stereopsis.

Results:

At 12 months, successful outcomes were achieved in 13 of 27 patients (46%) in the bilateral lateral rectus recession group and 19 of 28 patients (70%) in the unilateral lateral rectus recession group, which was not a statistically significant difference (
P
= .10). Survival analysis showed a trend toward a higher rate of failure in the bilateral lateral rectus recession group compared to the unilateral lateral rectus recession group (
P
= .04). The mean surgical dose-response was 1.7 PD/mm at 1 week and 1.0 PD/mm at 12 months for the bilateral lateral rectus recession group, and 2.0 PD/mm at 1 week postoperatively and 1.4 PD/mm at 12 months postoperatively for the unilateral lateral rectus recession group. There were no cases of long-term postoperative lateral incomitance in either group.

Conclusions:

Unilateral lateral rectus recession and bilateral lateral rectus recession have similar success rates for small angle intermittent exotropia after at least 12 months of follow-up. Randomized controlled trials in surgical management of intermittent exotropia should consider unilateral lateral rectus recession as a treatment arm.

Published: February 2022

The current study sought to create a developmental bibliotherapy material database (DBMD) and examine the effectiveness of developmental bibliotherapy on subjective well-being of older adults living in nursing homes. Based on the reading needs of older adults, we developed a DBMD, which included 327 materials with five themes:
Health Care
,
Current Affairs and Politics
,
Historical Biographies
,
Geriatric Culture
, and
Psychological Adjustment
. Fifty-four single materials were randomly selected from the DBMD to perform the intervention. This study used a quasi-experimental, single-group pre-/post-survey approach. Sixty-four older adults participated in the study for 6 weeks. Immediately before and after the intervention, older adults completed the Optimism-Pessimism Scale and Memorial University of Newfoundland Scale of Happiness. There were significant improvements in older adults' optimistic tendency and subjective well-being (
p
< 0.05). Reading materials in the DBMD promoted older adults' optimistic attitude toward life, reduced negative emotions, and improved subjective well-being. [

Lagrangian decomposition for stochastic TIMES energy system optimization model
Authors: Zhu Yujun ,   School of Mathematics and Statistics, Huazhong University of Science and Technology, Wuhan, China, Ming Ju ,   School of Mathematics, University of Edinburgh, Edinburgh, U.K
Published: February 2022

Energy system optimization models play an essential role in current decision support on topics including energy security, sustainable development and environmental protection from industrial, regional, national and even global perspective. One of the key energy system optimization models applied in international energy policy is TIMES. The article establishes two basic deterministic TIMES models which cover an energy commodity (coal or gas), a three-step supply curve and an end-use energy service demand. Then we convert the deterministic TIMES models into a stochastic optimization problem with multiple scenarios, and implement the Lagrangian decomposition approach in solving the stochastic programming models. The numerical experiment shows the feasibility of the Lagrangian decomposition algorithm to solve stochastic TIMES models with a small amount of scenarios, and analyze several reasons for non-convergence cases including the choice of step length and initial values of Lagrangian multipliers.
Mean-field limit of collective dynamics with time-varying weights
Authors: Duteil Nastassia Pouradier
Published: February 2022

In this paper, we derive the mean-field limit of a collective dynamics model with time-varying weights, for weight dynamics that preserve the total mass of the system as well as indistinguishability of the agents. The limit equation is a transport equation with source, where the (non-local) transport term corresponds to the position dynamics, and the (non-local) source term comes from the weight redistribution among the agents. We show existence and uniqueness of the solution for both microscopic and macroscopic models and introduce a new empirical measure taking into account the weights. We obtain the convergence of the microscopic model to the macroscopic one by showing continuity of the macroscopic solution with respect to the initial data, in the Wasserstein and Bounded Lipschitz topologies.
RECONSTRUCTING THE SHIP MOTIONS USING COMBINED MARINE SYSTEMS SIMULATOR TOOLBOX AND A SIX-DOF STEWART PLATFORM

Published: February 2022

Characterization of ship motions is greatly essential in evaluating performance of the ship or a ship mounted subsystems. This paper addresses such a challenge by proposing a methodology on reconstructing the ship motions using combined Marine Systems Simulator (MSS) toolbox and a six-DoF Stewart platform. Given the specifications of the ship, Stewart platform and Inertial Measurement Unit (IMU) system, ship motions are generated and then reconstructed by a six-DoF Stewart platform as a validation. Finding results show that the ship motions are able to be reconstructed and its randomness can be captured with considerable accuracy. However, as the sea state code increases, the accuracy of the proposed method decreases as indicated by the values of sum square error (SSE) of the reconstructed motions. Hence, the proposed methodology can be recommended as ocean waves based ship motions simulator as well as other dynamics system motion simulators.

Published: February 2022

The increasing demand for goods transportation inherent the risks of the terminal congestion, consequently decreasing the operational efficiency. Maritime transportation containerization has forced container terminals to carefully evaluate how to manage their yard operations. Nowadays, with the Internet of Things (IoT) and the development of data
technologies the complexity of data within and around the terminal has been increased, and a lack of data-driven approaches in this matter can still be identified. Using data mining techniques, some effects that are producing inefficiency might be discovered and fixed. This paper presents a data-mining approach to extract useful information from the terminal daily operations report. Additionally, it is shown the container's length of stay of a Straddle Carrier system container terminal.

Published: February 2022

Autopilot is a system control application on moving vehicles which serves to stabilize the direction of motion in the desired time and the programmed path's direction. The autopilot control system is controlled by a series of microcontrollers and GPS that has the function to be able to determine and the desired object. A control system is needed to control the boat to its destination. This system is broadly divided into two parts: the control station part and the autopilot unmanned ship part. These two parts communicate with each other using LoRa device. The data sent from the control station to the autopilot unmanned ship is target latitude and longitude coordinates. The autopilot unmanned ship will send feedback in the form of boat latitude and longitude coordinates so that users can find out the current location of the boat. The control station will send feedback from the boat to a database that can be monitored via the website to find out the boat's current condition on the website. The multi interface communication module was designed, implemented and evaluated, which was to transfer low-power, long-range large amount of data using MQTT and LoRa.
BENCHMARK TESTS OF FINETM/MARINE CFD CODE FOR THE CALCULATION OF SHIP RESISTANCE AT HIGH FROUDE NUMBERS
Authors: Suastika I K , Fauzi A F , Saputra A S , Utama I K A P , Firdhaus A , Sutardi  , Hariadi M
Published: February 2022

Benchmark tests of FINETM/ Marine CFD code were performed to verify the ship-resistance calculation results at high Froude numbers. The CFD code solves the Reynolds-averaged Navier-Stokes (RANS) equations with modelling of the free surface effects, that is, the generation of waves due to the ship movement on the water surface. A high-speed OSV boat was considered at three speeds (17, 20 and 26 knots), which correspond to the Froude numbers based on the volume of displacement FrV = 1.29, 1.52, and 1.98.The CFD results show a good agreement with the results of Savitsky’s formula and the numerical results obtained from Maxsurf Modeller. Further, a reasonable agreement was found between the CFD results and available experimental data. Flow visualisations show that the wave pattern behind the boat consists of transverse and divergent waves. As the boat’s speed increases, the wave height increases, and the wave pattern becomes more dominated by the divergent waves. These observations are consistent with the classical analytical predictions.

Published: February 2022

On small boats, hull design that provides a smaller value of ship resistance is usually preferred. Therefore, it is necessary to consider the selection of the hull shape provides optimum resistance. The used of multihull known as alternative to reduce ship resistance. This study investigated comparison of the resistance of fishing vessels ±15 GT. The analysis will be carried out on 4 ship hull models, U-shaped and V-shaped monohull, streamlined and asymmetrical hull catamaran. Assuming the main dimension is constant, the differences in displacement, WSA, frictional resistance and total resistance were analysed. Furthermore, a comparative analysis was carried out at several speed variations. Based on the study, it is known that the catamaran hull model provides less resistance than the monohull. The asymmetric catamaran provides the smallest ship resistance, but the reduction of ship resistance is accompanied by significant reduction in displacement. While the U-shaped monohull model shows the opposite.

Published: February 2022

The field of electronic games is a great experimental area that contributes to the implementation of new technologies in a variety of applications. This article explores the field of mixed reality through the use of physical computing for the development of the electronic game Inside. In such an interactive environment, the physical and the virtual worlds coexist and interact with each other. A user can alter the virtual world's characteristics through a special controller designed for the game that contains electronic components that can sense real-world properties. The attention of the user is not focused only on the screen but also on the controller through which a two-way interaction is achieved. A virtual environment created by a game engine can receive messages from the controller and vice versa. Changes on the properties of the virtual world can be communicated to the controller aiming at the alteration of the characteristics of the physical world. As a result, the user experiences an immersion in an environment in which real and virtual objects coexist.

Virtual reality exposure therapy (VRET) has been widely acknowledged as an effective alternative for in vivo exposure therapy (iVET). So far, previous research focused on long- and short-term effectiveness and comparisons to iVET, whereas the impact of design choices is understudied. Hence, the present study focuses on the effectiveness of several types of anxiety cues for the manipulation of anxiety. More specifically, five interoceptive cues (i.e., “fake” bodily sensations for tunnel vision, light flickering, heartbeat audio, blurred vision, and dizziness) and a physical cue (i.e., heat stimulation) are implemented in the VRET design of a within-subjects experiment with people who have claustrophobic and panic tendencies (N = 24). Results show that adding interoceptive cues significantly increased reported levels of anxiety, independent of the type of interoceptive cue. However, introducing a physical cue in VRET can also be effective but has no real added value when combined. Studies focusing on the design of anxiety cues can be valuable in understanding the effectiveness of VRET.
Intelligent Models for Stock Price Prediction

Published: February 2022

Prediction of the stock price is a crucial task as predicting it may lead to profits. Stock price prediction is a challenge owing to non-stationary and chaotic data. Thus, the projection becomes challenging among the investors and shareholders to invest the money to make profits. This paper is a review of stock price prediction, focusing on metrics, models, and datasets. It presents a detailed review of 30 research papers suggesting the methodologies, such as Support Vector Machine Random Forest, Linear Regression, Recursive Neural Network, and Long Short-Term Movement based on the stock price prediction. Aside from predictions, the limitations, and future works are discussed in the papers reviewed. The commonly used technique for achieving effective stock price prediction is the RF, LSTM, and SVM techniques. Despite the research efforts, the current stock price prediction technique has many limits. From this survey, it is observed that the stock market prediction is a complicated task, and other factors should be considered to accurately and efficiently predict the future.
Soft Biometrics Authentication
Authors: Sobabe Abdou-Aziz , Djara Tahirou , Blochaou Blaise , Vianou Antoine
Published: February 2022

This manuscript presents the design of a new approach of human skin color authentication. Skin color is one of the most popular soft biometric modalities. Since a soft biometric modality alone cannot reliably authenticate an individual, this new system is designed to combine skin color results with other pure biometric modalities to increase recognition performance. In the classification process, we first perform facial skin detection by segmentation using the thresholding method in the HSV color space. Then, the K-means algorithm of the clustering method is used to determine the dominant colors on the skin pixels in the RGB model. Variations according to the R, G and B components are recorded in a reference model to enable an individual’s identity to be predicted on the basis of 30 clusters. Experimental results are promising and give a false acceptance rate (FAR) of 29.47% and a false rejection rate (FRR) of 70.53%.
Fetal Liver–Derived Alveolar-like Macrophages: A Self-Replicating Ex Vivo Model of Alveolar Macrophages for Functional Genetic Studies
Authors: Thomas Sean T , Wierenga Kathryn A , Pestka James J , Olive Andrew J
Published: February 2022

Alveolar macrophages (AMs) are tissue-resident cells in the lungs derived from the fetal liver that maintain lung homeostasis and respond to inhaled stimuli. Although the importance of AMs is undisputed, they remain refractory to standard experimental approaches and high-throughput functional genetics, as they are challenging to isolate and rapidly lose AM properties in standard culture. This limitation hinders our understanding of key regulatory mechanisms that control AM maintenance and function. In this study, we describe the development of a new model, fetal liver–derived alveolar-like macrophages (FLAMs), which maintains cellular morphologies, expression profiles, and functional mechanisms similar to murine AMs. FLAMs combine treatment with two key cytokines for AM maintenance, GM-CSF and TGF-β. We leveraged the long-term stability of FLAMs to develop functional genetic tools using CRISPR-Cas9–mediated gene editing. Targeted editing confirmed the role of AM-specific gene Marco and the IL-1 receptor Il1r1 in modulating the AM response to crystalline silica. Furthermore, a genome-wide knockout library using FLAMs identified novel genes required for surface expression of the AM marker Siglec-F, most notably those related to the peroxisome. Taken together, our results suggest that FLAMs are a stable, self-replicating model of AM function that enables previously impossible global genetic approaches to define the underlying mechanisms of AM maintenance and function.
Glucose transporters as markers of diagnosis and prognosis in cancer diseases
Authors: Szablewski Leszek
Published: February 2022

Glucose is a main metabolic substrate, which plays a role as a source of energy and a substrate in several processes. Cell membrane is lipophilic, whereas monosaccharides are hydrophilic. Therefore, lipid bilayer is impermeable for these substances and they need specific carrier proteins. Glucose metabolism in cancer cells differs from this process in normal cells. Cancer cells prefer the process of glycolysis, which generates less molecules of ATP than complete oxidative breakdown, therefore cancer cells need more molecules of glucose. Increased uptake of glucose is due to changes in expression of glucose transporters. Several glucose transporters are overexpressed in cancer cells, however, there are also observed decreased levels of these proteins in cancer cells. There are observed specific correlations between cancer and expression of glucose carrier proteins. Therefore, changes in expression of glucose transporters in cancers may be treated as a marker of diagnosis and/or prognosis for cancer patients.
Building blocks for a public health ethics framework for the geriatric community

Published: February 2022

Background: The elderly population is steadily growing in South Africa. However, there is limited strategic planning or policy initiatives to address this group’s vulnerability resulting in several public health ethical issues that need to be considered and addressed. This article aims to develop a public health ethics framework for the geriatric community with the purpose to review ethical implications when working with the geriatric community.Methods: The Q-methodology was selected for data collection. Fifteen statements were ranked by means of a five-point Likert-scale questionnaire. Twenty-two participants from six geriatric institutions participated in the ranking of the statements.Results: The ranking of the statements confirmed the need for a public health ethics framework to provide guidance when working with the geriatric community and to evaluate decisions about geriatric care. Such a framework should be application-based and practice-oriented which can assist in addressing unfamiliarity with public health ethics in general and can extend the capacity for decision-making. The ranking of these statements contributed to the scope of the planned framework, by considering the vulnerability of healthcare practitioners (as community of practitioners) and the geriatric community as a basis from which to promote justice in public health programmes.Conclusion: Based on the ranking of statements, eight building blocks for a public health ethics framework were identified. The building blocks are imbedded in professional ethics and care ethics. The proposed framework can give rise to social justice in public health and the ability to evaluate what the ethical implications are for public health policies, programmes and interventions aimed at the geriatric community.
Fatal non-accidental injury in South Africa: A Gauteng hospital’s perspective on the incidence and fracture types in post-mortem skeletal surveys
Authors: Wessels Robyn M. , Moodley Halvani
Published: February 2022

Background: In its severest form, non-accidental injury (NAI) in children is fatal. South Africa has been reported to have double the global average of child homicides. Autopsy is the main investigation in fatal NAI with post-mortem skeletal surveys (PMSS) playing an adjunctive role. Whilst fracture patterns associated with NAI in living patients have been established, this has not been investigated in PMSS in South Africa.Objectives: To determine the incidence and characteristics of fractures in suspected fatal NAI cases. To calculate the incidence of fractures according to high-, moderate- and low-specificity fracture locations for NAI.Methods: A retrospective review of all PMSS performed between 01 January 2012 and 03 December 2018 was conducted at the Charlotte Maxeke Johannesburg Academic Hospital.Results: Of the 73 PMSS, 33 (45.2%) demonstrated fractures. No statistical significance in sex was found: 38 (52.1%) were male and 35 (47.9%) were female (p  0.05). The mean age of those who sustained fractures was 28 months (standard deviation [s.d.]: 21 months). A total of 115 fractures were sustained, of that the top five bones fractured were the ribs 37 (32.2%), parietal bone 13 (11.3%), ulna 13 (11.3%), femur 13 (11.3%), and radius 11 (9.6%). High-specificity fracture locations accounted for 40/133 (30.1%).Conclusion: The fracture types in PMSS were similar to those in live skeletal surveys. Our study’s fracture rate was higher in comparison to international studies. The PMSS is a valuable adjunct to autopsy in detecting occult fractures of the limbs. We recommend that PMSS be performed in suspected fatal NAI cases at least in children up to 24 months of age.

ABSTRACT

Background:

There is strong evidence that the prevalence of chronic conditions substantially increases with age as multimorbidity the coexistence is associated with poor quality of life and health outcome.

Objective:

The objective of this study is to assess the psychosocial medical domains and their association with well-being among the Geriatrics.

Materials and Methods:

A community-based cross-sectional study at Urban Health Training Center, Jeedimetla including all the participants whose aged 60 years and above with written consent. A total of 140 participants were subjected to “Integrated care tool” brief questionnaire by interview schedule method including domains such as physical, functional, psychological, mental health, geriatric syndromes, financial security, social involvement, and elder abuse. The association between various domains and well-being was analyzed using binary logistic regression analysis.

Results:

The well-being was affected among 72.9% mainly suffering with noncommunicable diseases such as hypertension and related complications. Higher mean scores were recorded for those whose well-being is affected for the domains such as physical, geriatric syndromes 1 and 2, mental health, social and family security, and elder abuse. On binary logistic regression analysis, the main predictors for their affected well-being were elder abuse and geriatric syndromes.

Conclusions:

This gives a comprehensive health status of geriatrics with domain-wise classification of health care needs, thereby improving the health-seeking behavior and preventing frequent hospitalization and related complications.

Objective:

The objective of this study is to delineate the characteristics and outcome of Pediatric Inflammatory Multisystem Syndrome temporally associated with severe acute respiratory syndrome coronavirus 2 (SARSCoV2) infection (PIMS-TS) in Eastern Indian settings.

Materials and Methods:

We conducted a prospective observational multicentric study from May 2020 to August 2020, collecting data on clinical profile, investigation findings, and outcome of the children aged 1 month–12 years admitted with the features of coronavirus disease 2019 (COVID-19) related hyperinflammation satisfying criteria for PIMS-TS from three tertiary care hospitals of Kolkata.

Results:

A total of 38 patients fulfilling the criteria of PIMS-TS were recruited. The median age of the study population was 5 years (1.9–8 years). Gastrointestinal symptoms were present in 33 (86.6%) of patients. Nasopharyngeal swab for COVID-19 reverse transcriptase-polymerase chain reaction was positive in 19 (50%) of patients, and immunoglobulin G antibody against COVID-19 was found in 12 (66.6%) of patients, whereas 19 (50%) of patients had a positive contact history of SARS-Co-V2 exposure. The features of Kawasaki, like illness with coronary changes, were seen in 12 (32%) cases, whereas myocarditis with ejection fraction <55% was reported in 17 (45%) of patients. Intensive care admissions were needed in 27 (71%) patients, and inotropes were given in 18 (47%), whereas four patients required mechanical ventilator support. Immunotherapy was used in 32 (84%) of patients. The outcome was good, with one death.

Conclusions:

PIMS TS has varied clinical presentation ranging from milder cases to severe cardiac dysfunction with shock. However, timely intervention and prompt initiation of immunomodulators can improve the prognosis.

Authors: Khuje Prashant Devidas , Karandikar Mahesh S. , Sable Bharti U.
Published: February 2022

Background:

Blood group determination is done by the slide test and tube test. Grading/scoring of hemagglutination reactions is performed through the naked eye and microscopy to detect spurious (false positive and negative) reactions.

Objectives:

In our observational study, comparative scoring of ABO and Rh hem-agglutination reactions was done based on degree of hemolysis and agglutination through the macroscopic and microscopic technique.

Materials and Methods:

The determination of blood group of 209 participants was done by the porcelain slide method using commercially prepared antisera (manufactured by TULIP DIAGNOSTICS (P) LTD.) containing anti-A, anti-B, and anti-D monoclonal antibodies followed by scoring/grading based on degree of hemolysis and red blood cell clumping. The data were statistically analyzed using the Chi-square test and Z-test of proportion.

Results:

ABO hemagglutination reactions showed significantly higher score ([A-Macro Z = 7.153, Micro Z = 4.65] [B-Macro Z = 11.17, Micro Z = 21]) (Z >2.5, P < 0.001) than Rh hemagglutination reactions. B hemagglutination reactions showed insignificantly higher score (B-Macro Z = 1.29, Micro Z = 1.816) (Z <1.95, P < 0.05) than A hemagglutination reaction.

Conclusion:

ABO hemagglutination reactions showed significantly higher score than Rh hemagglutination reactions as ABO system agglutinin are pentavalent (immunoglobulin M) binding 10 agglutinogens while that of Rh system are bivalent binding 4 agglutinogens. B hemagglutination reactions showed insignificantly higher score than A hem-agglutination reaction which required further evaluation.

Background:

Diarrhea is a major cause of childhood morbidity and mortality in both developing and developed countries. It remains a common cause of hospitalization worldwide. Rotavirus is a cause of acute watery diarrhea in children under five years of age. The incidence of diarrhea decreases with increasing age.

Aim:

This study aimed at finding some risk factors associated with rotavirus infection in children <five years of age presenting with acute diarrhea at the university of Maiduguri teaching hospital.

Patient, Materials and Methods:

This is a cross-sectional study. A total of 173 children <five years presenting with diarrhea of <two weeks were recruited for the study. Stool samples were collected, and rotavirus antigen was detected using immunochromatographic, and the positive sample was then further analyzed using reverse transcriptase polymerase chain reaction for the VP4 and VP7 genotyping. The risk factors were analyzed using multivariate analysis conditional regression model after collecting data using a well-structured questionnaire.

Results:

The Source of water supply and presence of persons with gastroenteritis in the household were found to be risk factors for acquiring the infection with statistically significant P < 0.05. Breastfeeding was found to be protective of rotavirus gastroenteritis.

Conclusion:

Rotaviruses cause morbidity and mortality in children under five years of age. In view of the associated risk factors, making available safe drinking water and encouraging good personal hygiene is important. Promotion of exclusive breastfeeding and vaccination is advocated. Public health strategies like creating awareness to affected communities are a good strategy.
