Observations and simulations of interacting galaxies and mergers in the local universe have shown that interactions can significantly enhance the star formation rates (SFRs) and fueling of active galactic nuclei (AGN). However, at higher redshift, some simulations suggest that the level of star formation enhancement induced by interactions is lower due to the higher gas fractions and already increased SFRs in these galaxies. To test this, we measure the SFR enhancement in a total of 2351 (1327) massive (M

We find that the level of SFR enhancement is a factor of ∼1.5 higher at 0.5 < z < 1 than at 1 < z < 3 in the closest projected separation bin. Among a sample of visually identified mergers, we find an enhancement of a factor of

Published: November 2022

We have explored the dynamical and mass evolution of halos driven by large-scale filaments using a dark-matter-only cosmological simulation with the help of a phase-space analysis. Since a nonnegligible number of galaxies are expected to fall into the cluster environment through large-scale filaments, tracking how halos move around large-scale filaments can provide a more comprehensive view on the evolution of cluster galaxies. Halos exhibit orbital motions around filaments, which emerge as specific trajectories in a phase space composed of halos’ perpendicular distance and velocity component with respect to filaments. These phase-space trajectories can be represented by three cases according to their current states. We parameterize the trajectories with halos’ initial position and velocity, maximum velocity, formation time, and time since first crossing, which are found to be correlated with each other. These correlations are explained well in the context of the large-scale structure formation. The mass evolution and dynamical properties of halos seem to be affected by the density of filaments, which can be shown from the fact that halos around denser filaments are more likely to lose their mass and be bound within large-scale filaments. Finally, we reproduce the mass segregation trend around filaments found in observations. The mass segregation has been developed because halos that formed earlier approached filaments earlier, grew efficiently, and ended up being more massive. We also found that dynamical friction helps to retain this segregation trend.

James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) images of the luminous infrared (IR) galaxy VV 114 are presented. This redshift ∼0.020 merger has a western component (VV 114W) rich in optical star clusters and an eastern component (VV 114E) hosting a luminous mid-IR nucleus hidden at UV and optical wavelengths by dust lanes. With MIRI, the VV 114E nucleus resolves primarily into bright NE and SW cores separated by 630 pc. This nucleus comprises 45% of the 15 μm light of VV 114, with the NE and SW cores having IR luminosities, L

Mostly notably, filamentary polycyclic aromatic hydrocarbon (PAH) emission stochastically excited by UV and optical photons accounts for half of the 7.7 μm light of VV 114. This study illustrates the ability of JWST to detect obscured compact activity and distributed PAH emission in the most extreme starburst galaxies in the local universe.

Oreocharis qianyuensis, a new species of Gesneriaceae from Southwest, China, is described and illustrated based on morphological comparisons and molecular phylogenetic analyses. Phylotranscriptomic analyses of the new species in the context of a comprehensive phylogeny with dense sampling of 88% (111/126) of all species of the genus indicated that the new species was most closely-related to O. fargesii. The new species is morphologically similar to O. fargesii and O. nanchuanica in the shape, color and structure of flowers and the number of stamens, but differs in the leaf blade shape, margin and the indumentum characters of the inflorescence. Its morphological relationship with similar species is discussed, the detailed descriptions, colour photographs, distribution, as well as the IUCN threatened status based on the IUCN Red List Categories and Criteria are also provided.
The intraspecific variation of morphology and coloration of field crickets: a taxonomic revision of Chinese Gymnogryllus Saussure, 1877 and Phonarellus Gorochov, 1983 (Orthoptera, Gryllidae, Gryllini)
Authors: Wang Ning , Huang Huateng , Ma Li-Bin
Published: November 2022

After extensive sampling of specimens from species found in China, we examined the intraspecific morphological variation of several characters used for species delimitation in two closely related cricket genera, Gymnogryllus Saussure, 1877 and Phonarellus Gorochov, 1983. We found that the characters (male genitalia in Gymnogryllus odonopetalus Xie & Zheng, 2003 and Phonarellus ritsemae (Saussure, 1877), and coloration of the hind leg in Phonarellus minor (Chopard, 1959)) exhibit considerable amounts of variation within species, and are thus not reliable characters for species differentiation. Therefore, we revised the taxonomy of these two genera. Five synonyms are proposed: G. yunnanensis (= G. odonopetalus) syn. nov., G. striatus (= G. odonopetalus) syn. nov., G. longus (= G. odonopetalus) syn. nov., G. tumidulus (= G. odonopetalus) syn. nov., and P. flavipes (= P. minor) syn. nov. All species mentioned above are described and illustrated. Keys and a distribution map are provided.
Musculoskeletal Surgery in Psoriatic Arthritis: Prevalence and Risk Factors
Authors: Kwok Timothy S.H. , Sutton Mitchell , Cook Richard J. , Pereira Daniel , Chandran Vinod , Gladman Dafna D.
Published: November 2022

Objective

Despite medical therapy, damage occurs in patients with psoriatic arthritis (PsA) requiring musculoskeletal (MSK) surgery. We aimed to describe MSK surgery in patients with PsA and identify risk factors for undergoing first MSK surgery attributable to PsA.

Methods

A single-center cohort identified patients with PsA fulfilling Classification Criteria for Psoriatic Arthritis who had MSK surgery between January 1978 and December 2019 inclusive. Charts were reviewed to confirm surgeries were MSK-related and attributable to PsA. Descriptive statistics determined MSK surgery prevalence and types. Cox proportional hazards models evaluated clinical variables for undergoing first MSK surgery using time-dependent covariates. Using a dataset with 1-to-1 matching on markers of PsA disease severity, a Cox proportional hazards model evaluated the effect of targeted therapies, namely biologics on time to first MSK surgery.

Results

Of 1574 patients, 185 patients had 379 MSK surgeries related to PsA. The total number of damaged joints (hazard ratio [HR] 1.03,P< 0.001), tender/swollen joints (HR 1.04,P= 0.01), presence of nail lesions (HR 2.08,P< 0.01), higher Health Assessment Questionnaire scores (HR 2.01,P< 0.001), elevated erythrocyte sedimentation rate (HR 2.37,P= 0.02), and HLA-B27 positivity (HR 2.22,P= 0.048) were associated with increased risk of surgery, whereas higher Psoriasis Area Severity Index (HR 0.88,P< 0.002) conferred a protective effect in a multivariate model. The effect of biologics did not reach statistical significance.

Conclusion

MSK surgery attributable to PsA is not rare, affecting 11.8% of patients. Markers of cumulative disease activity and damage are associated with a greater risk of requiring surgery.
Le toucher maternel « gentle touch » : une invitation à une danse tactile ?
Authors: Rivas-Smits Cristina , Bertels Julie , McGlone Francis , Van Puyvelde Martine
Published: November 2022

Les touchers « Gentle Touch Stimulation » (GTS) sont des touchers affectifs doux qui fournissent une stimulation optimale des afférents C-tactile (CT). De nombreuses recherches ont montré que cette sous-classe spécifique de nerfs non-myélinisés cutanés mécano-sensoriels joue un rôle dans la régulation physiologique du système nerveux autonome et dans le développement social du nourrisson. L’objectif de cette étude était d’examiner l’effet d’une intervention quotidienne de touchers GTS sur la fréquence et la durée des touchers GTS maternels lors du moment de réunion, après une procédure Still Face (SF). Pour répondre à cette interrogation, un groupe d’intervention (GTS) a été comparé à un groupe témoin (CTRL). Les nourrissons étaient âgés de 6 à 12 semaines. Les mesures ont été prises à deux reprises, espacées d’un mois. Nous avons effectué une micro-analyse seconde par seconde de trois types de touchers pendant le moment de réunion : (i) toucher GTS, (ii) contact physique et (iii) absence de contact physique. Nos résultats montraient qu’avec le temps la durée moyenne des touchers GTS devenait significativement plus courte dans les deux groupes et que cette durée semblait correspondre à la moyenne des moments présents. Les moments sans contact avaient diminué plus dans le groupe GTS que dans le groupe CTRL. De plus, la durée maximale de contacts physiques (non-GTS) devenait plus longue dans les deux groups. Nous émettons l’hypothèse que le toucher GTS devient plus efficace avec le temps et par conséquent plus court en duration pour obtenir son effet régulateur. Nous offrons ainsi une réflexion autour du rôle que les touchers GTS pourraient jouer dans le développement de l’intersubjectivité en utilisant les théories des moments présents d’intersubjectivité de Stern.
Se mobiliser pour défendre un programme d’études : le cas des étudiants en droit de l’Université libre de Bruxelles (1835-1850)

Published: November 2022

Au cours des quinze années qui forment, à la suite de la loi organique de l’enseignement supérieur du 27 septembre 1835, la période de « mise en place » de l’enseignement universitaire en Belgique, le gouvernement cherche à approfondir le programme d’examen des études juridiques. Cette décision génère un mouvement de contestation chez les étudiants en droit qui considèrent que le programme d’examen est déjà trop important. Afin de saisir les enjeux de cette mobilisation, l’objectif visé par la présente contribution est triple. Il s’agit d’identifier la nature des actions menées par ces étudiants, de comprendre la façon dont le mouvement se structure afin de porter leurs revendications auprès du gouvernement et enfin étudier la réception par ce dernier des demandes des étudiants. Dans ce cadre, notre regard se concentre plus particulièrement sur un groupe spécifique : les étudiants en droit de l’université de Bruxelles.
Construire l’internationalisme. Communication, adaptation et réseaux des étudiants étrangers de l’Université Nouvelle de Bruxelles (1894-1914)
Authors: Elmer Margot
Published: November 2022

L’histoire des universités a longuement occulté l’étude des étudiants et étudiantes, se concentrant principalement sur des enjeux institutionnels. Même si des travaux se multiplient ces dernières années à ce sujet, ceux-ci se cantonnent souvent à des analyses socio-économiques et mettent peu en évidence la capacité d’action de ces acteurs. À l’inverse, cet article entend aborder les étudiants étrangers comme autant d’intermédiaires décisifs dans la constitution de ponts entre leurs pays d’origine et l’université qui les accueille. Basé sur le cas de l’Université Nouvelle de Bruxelles, université belge active de 1894 à 1919 et composée en majorité d’étudiants venus d’Europe de l’Est, cet article s’intéresse à la mise en place par les étudiants de diverses stratégies de communication avec le secrétariat, aux demandes de changements structurels qu’ils adressent pour répondre aux problématiques internationales qui les concernent et enfin, à la création de réseaux à Bruxelles pour s’entraider dans leur vie quotidienne. En d’autres termes, cet article fait la part belle aux rôles des étudiants étrangers dans la constitution d’une culture académique internationalisée durant la Belle Époque.
Development of an ophthalmic formulation with a postbiotic of Lactiplantibacillus plantarum CRL 759
Authors: Layús B.I. , Gerez C.L. , Rodriguez A.V.
Published: November 2022

The term postbiotics has acquired great interest in recent years. Numerous studies have shown a potential beneficial effect of its use in many inflammatory pathologies. However, it has not been much explored in ocular inflammatory diseases. The aims of this study were to develop and characterise an ophthalmic formulation with a postbiotic of Lactiplantibacillus plantarum CRL 759, and to evaluate its anti-inflammatory actions on murine macrophage stimulated with lipopolysaccharides (LPS) in vitro. First, we evaluated the ability of L. plantarum CRL 759 to generate a supernatant with anti-inflammatory property using different buffers. Then, we studied the stability at different temperatures and storage times of the generated postbiotic. In vitro assays showed that incubation of L. plantarum CRL 759 in modified phosphate buffer according to Sorensen (called POF-759), generated a supernatant that significantly reduced the production of interleukin-6, tumour necrosis factor-α, and nitric oxide by RAW 264.7 cells stimulated with LPS. Furthermore, POF-759 maintained its anti-inflammatory activity at room temperature, 4 and -20 °C, up to 30 days of storage. From the studies reported here, a postbiotic product with anti-inflammatory properties and optimal characteristics for the formulation of eye drops was obtained.
Adult behaviour as the next frontier for optimising industrial production of the black soldier flyHermetia illucens (L.) (Diptera: Stratiomyidae)
Authors: Meneguz M. , Miranda C.D. , Cammack J.A. , Tomberlin J.K.
Published: November 2022

The black soldier fly is the ‘crown jewel’ of the insects as feed industry. Over the past two decades, a tremendous amount of research has been published on larval development, uses of the process, and the biomass generated. However, outside of knowing that adults lek in the wild, and that they rely on components of sunlight to mate, little is known about the adult biology. Given that industrial producers are reliant on the adult to produce offspring, digests organic substrates to produce insect biomass for use as feed, this lack of information on adult behaviour and biology has potentially limited the ability of the industry to optimally mass produce this insect. The motive of this review is to provide a foundation that can serve as a launching pad for future research on the black soldier fly, which could lead to organised results that are comparable across studies and can be used to optimise breeding-systems globally.
Approximate solution of the shortest path problem with resource constraints and applications to vehicle routing problems
Authors: Lamamri Abdelkader , Hachama Mohammed
Published: November 2022

Vehicle routing problem (VRP) is a fundamental combinatorial optimization and integer programming problem with several important applications. The VRP is usually solved by using branch-and-bound techniques requiring solving a shortest path problem with resource constraints (SPPRC) and the determination of a lower bound, which can be computed by using column generation. The SPPRC entails finding the minimum cost elementary path in a valuated graph that is subject to constraints on resource consumption. The proposed exact solutions to this hard NP-hard problem require an excessive computation time which increases with the number of resources. In this paper, we propose a new approximate resolution of the SPPRC for acyclic and cyclic graphs. Our method is based on a Lagrangian relaxation of a subset of the constraints and using dominance only on a subset of the resources. This reduces the search space and allows users to efficiently compute solutions used to improve the column generation procedure. Extensive evaluation and comparison to the classical exact method show that the proposed algorithm achieves a good compromise between efficiency and quality of the SPPRC and the VRP solutions. Thus, our method can be used for practical large-scale VRP applications.
Remaining useful life prediction of the lithium-ion battery based on CNN-LSTM fusion model and grey relational analysis
Authors: Chen Dewang , Zheng Xiaoyu , Chen Ciyang , Zhao Wendi
Published: November 2022

The performance of lithium-ion batteries will decline dramatically with the increase in usage time, which will cause anxiety in using lithium-ion batteries. Some data-driven models have been employed to predict the remaining useful life (RUL) model of lithium-ion batteries. However, there are limitations to the accuracy and applicability of traditional machine learning models or just a single deep learning model. This paper presents a fusion model based on convolutional neural network (CNN) and long short-term memory network (LSTM), named CNN-LSTM, to measure the RUL of lithium-ion batteries. Firstly, this model uses the grey relational analysis to extract the main features affecting the RUL as the health index (HI) of the battery. In addition, the fusion model can capture the non-linear characteristics and time-space relationships well, which helps find the capacity decay and failure threshold of lithium-ion batteries. The experimental results show that: 1) Traditional machine learning is less effective than LSTM. 2) The CNN-LSTM fusion model is superior to the single LSTM model in predicting performance. 3) The proposed model is superior to other comparable models in error indexes, which could reach 0.36% and 0.38e-4 in mean absolute percentage error (MAPE) and mean square error (MSE), respectively. 4) The proposed model can accurately find the failure threshold and the decay fluctuation for the lithium-ion battery.

Because the appearance of the critical reaction, we deal with the lack of compactness by using the concentration-compactness principle. In particular, we discuss the main results in non-degenerate and degenerate cases. And we apply combination of Krasnoselskii genus and the Hardy-Littlewood-Sobolev inequality to get the results of existence and multiplicity.
Remote Laboratory as an Educational Tool in Robotics Experimental Course
Authors: Pang Dangfeng , Cui Shigang , Yang Genghuang
Published: November 2022

A remote lab is a technology that allows participants to efficiently conduct experimental teaching where users can connect to lab equipment from anywhere without being in a specific physical location. The COVID-19 pandemic affects all areas of human activity. ​As a result, students did not receive face-to-face instruction, and access to the laboratory was limited or practically impossible, and access to laboratory facilities has been limited or nearly impossible. Especially in engineering education, students’ practical abilities cannot be developed comprehensively. In this paper, this paper built an online remote robotics experiment system using digital twin (DT) technology and IoT technology and adopted ADDIE (Analysis, Design, Development, Implementation, and Evaluation) teaching method. With these measures, students can design and debug robot programs at home, just like in the laboratory. This study sent questionnaires to 64 students, and 58 were returned. The results show that more than 80% of students believe that the remote labs for industrial robotics courses have improved the efficiency and quality of students' skills training as opposed to virtual simulation and watching videos on the computer.
The Mechanism of Teacher Influence on the Learning Engagement of Students
Authors: Wang Di
Published: November 2022

As a non-teaching factor, the influence of teachers can often trigger positive teaching effects, and exert impacts on students’ learning engagement. However, few of the existing studies on the online learning engagement of college students have viewed this topic from a quantitative perspective, and few have concerned about the influence mechanism of Teacher Influence (TI). To fill in this research blank, this paper studied the influence mechanism of TI on the learning engagement of students. At first, this paper analyzed the theories related to the said influence mechanism and proposed a TI model for the online teaching environment. Then, after investigating students’ understandings, participation, and questions with the online teaching activities created by teachers, the TI model was built in the paper. In view of the complexity of this TI model, this paper fully considered the meaning of the interactions of teacher and student nodes during the actual online teaching activities, proposed a two-stage TI maximization algorithm based on the learning input responses of the nodes, and realized comprehensive quantification of TI. The effectiveness of the proposed algorithm was verified by experimental results.

Published: November 2022

The low success rate of entrepreneurship is quite common for contemporary college students, and its main reason can be attributed to their lack of social experience and entrepreneurial guidance, thus, it’s of certain practical significance to study the social experience guidance for college students’ entrepreneurship and this paper aims to explore this problem based on social network. At first, this paper introduced the formation mechanism of the social experience guidance for college students’ entrepreneurship, proposed a novel Social Network Representation Learning (SNRL) method for college students’ entrepreneurship, which could attain more information of social experience guidance from networks with isomorphic substructures. Then, in the social network of college students’ entrepreneurship, this paper discussed the extraction method of structural subgraph of neighborhood space of college students and other entrepreneurial subject nodes, and proposed a method for building sub-networks similar to the scale and development state in the social network of college students’ entrepreneurship, and realized the information sharing of social and entrepreneurial experiences among sub-networks. At last, this paper constructed a Social and Entrepreneurial Experience Guidance (SEEG) model, and verified its effectiveness in experiments.

Published: November 2022

The growth of mobile commerce marketplaces worldwide has been boosted by modern advances in digital technology. However, Privacy and security are still concern in m-commerce application. Since the previous study has researched the link between security and privacy and purpose to use, the factors that influence the formation of privacy and security in m-commerce are mostly unidentified. On the basis of UTAUT2, this study investigates the factors of security and privacy effecting mobile commerce acceptance. A hybrid SEM-ANN method was utilized to identify non-linear and compensatory interactions. Compensatory and Linear models are based on the idea that a deficiency in one component might also be compensated for by other variables. Linear and Non-compensatory models, on the other hand, seem to overcomplicate buyer decision mechanisms. Survey criteria have been conducted to obtain 890 mobile commerce consumer’s datasets utilizing an application on m-commerce. The following are the results. (1) M-commerce acceptability and use were positively influenced by five determinants (Security, performance expectancy, effort expectancy, habit, and price value). (2) Un-authorization, Error, secondary usage, collection, control, and awareness were all shown to directly and significantly negatively impact M-COMMERCE acceptance and use. (3) Three additional variables (social influence, hedonic motivation, and facilitating conditions) did not affect customers' intentions to use m-commerce applications in Jordan. In m-commerce, the integrated model expects a 45% percent increase in security and privacy.

Published: November 2022

The data of impacts and damage caused by floods is necessary for manipulation to assist and relieve those impacts in each area. The main issue for data acquisition was acquisition methods that affect the durations, accuracy, and completeness of data obtained. Most data are currently obtained by field survey for data on impacts in each area. However, this method contains limitations, i.e., taking a long time, high cost, and no real-time data visualization. Thus, this research presented the study to develop an application for inspecting areas under impact and damage caused by floods using deep learning classification for flood classification and land use type classification in the affected areas using digital images, remote sensing data, and crowdsource data notified by users through the accuracy assessment application of classification. It was found that deep learning classification for flood classification had 97.50% accuracy, with Kappa = 0.95. Land use type classification had 93.71% accuracy, with Kappa = 0.91. Flood damage assessment process in this research was different from other previous research that used geospatial data for flood damage inspection, e.g., satellite images. In contrast, this research brought damage data notified by users for processing with flood data in each area by satellite image processing and land use types of classification. The proposed application can calculate damage in each area and visualize real-time results in maps and graphs on the dashboard via the application. Besides, the presented method can be used to verify and visualize data of areas under impact and damage caused by floods in different areas.

Authors: Tomažič Tina , Blažević Karmen , Pavlič Jani
Published: November 2022

Gender-neutral advertising has become an important approach in terms of digital consumers, shifting from traditional stereotyped values towards the inclusiveness of both genders. To examine the influence of gender-neutral advertising on digital consumers, the authors measured the attitude towards gender-neutral and gender-stereotyped advertisements. To this end, a questionnaire and within-study design were employed to gather responses to three advertisements of both types from the prevailing industries. Digital consumers showed a significantly higher advertising attitude score for gender-neutral advertisements. The results have important implications for marketers and researchers since gender-neutral advertising has become the prevailing form of gaining favourable impacts with digital consumers.

Authors: Garg Arshya , Garg Anu
Published: November 2022

Learning is an ongoing process throughout the lifetime of an individual. To continue learning and promote self-growth, one should continuously keep building and upgrading their skills and knowledge base. This agenda was unshaken even during the pandemic when students could not go in person to educational institutions. This led to the rise of online education which was largely accelerated with the help of new technology (i.e., neuromarketing). This discipline came into the picture when this emerging technology helped to analyse customer needs. Application of neuromarketing is the life jacket to survive the high tides of the marketing competition and make it to the consumer shore. In this chapter, the authors present a case study illustrating the application of neuromarketing in online education (i.e., Cuemath). It targeted the parent's concern of their child staying safe in addition to keep a track of their child's learning and performance with minimal hassle and cost without compromising on its quality and how neuromarketing fills in the gaps left by traditional marketing methods.

The researcher prepared a well-structured questionnaire and collected data from 150 customers on a convenient sampling method. The population of the study area is Kerala state. The study identified that any change in service quality and price will yield a 37% change in the dependent variable that is the loyalty of the customer. The study also found that there is a mediating effect between the independent and dependent variable. The researcher concluded that customer satisfaction is an important instrument for evaluating service providers' service quality, and it may be measured using customer expectations for a variety of services supplied by telecommunication service providers.
Unconscious Branding
Authors: Kumar Dinesh
Published: November 2022

Advertisements are on billboards, on TV and in newspapers, and on mobile phones. However, very little thought is given to the opposite effect of advertising – the effect on the self-perception of people. This chapter discusses unconscious effects of advertising – the self-image formed by consumers by seeing repeated images in advertisements. Gender roles are reinforced when ads show people in different roles. In particular, it describes the effect on society when images of women are shown in domestic roles. Subconsciously, an image is formed in the minds of people that both men and women have specific gender roles to play in society. The chapter further discusses how advertisements need to be more sensitive towards subliminal messages received by society. The advertising industry needs to move a step ahead and assess the impact of their work before releasing it on an unsuspecting public. Since people tend to believe what they see, reinforcing traditional roles in advertising images prevents women's emancipation and limits girls in their quest to become independent.

Access to quality healthcare is one of the fundamental human rights of every citizen irrespective of socio-economic status. In Nigeria access to quality and affordable health care by citizens, especially in rural areas, is a major challenge because many healthcare centres in rural areas do not meet the required health facilities standard for basic preventive and curative care. The Nigerian constitution specifies the need to make quality healthcare affordable for citizens, maintaining healthcare standards seems to be far from being achieved. The objective of the book chapter is to discuss the role of legislators in maintaining health care standards in Nigeria. A major role that the legislators can play to improve on standards is the establishment of agency by law that will monitor and enforce standard in States and Local Governments health facilities. The legislators can also amend the law establishing NPHCDA to provide for the establishment of Management Agencies to adequately ensure the maintenance of minimum standard structure for effectiveness of health care delivery.

In the country, thousands of patients die each year due to medical errors and improper treatment. This problem can be attributed primarily to human factor, medication error, and system failure. These problems require an urgent solution to be done. National Accreditation Board for Hospitals and Healthcare Providers (NABH) serves as a benchmark in this regard for improving patient safety and health quality care in the international community. It offers education, publication, advisory services and international accreditation and certification. This chapter demonstrates perceptions of 300 doctors, nurses, and paramedical staff regarding patient safety climate in the accredited and non-accredited hospitals with the help of a cross-sectional survey in Delhi NCT, India. The results revealed that senior leadership, resources for safety, facility characteristics, workgroup norms, learning, psychological safety, and problem responsiveness were responded highly positively in accredited hospitals.

In recent years, dental activity has undergone an important scientific and technological progress that has allowed the development of increasingly complex and reliable treatments, guaranteeing an increasingly effective protection of the patient's right to health. This evolutionary process, while involving a general increase in the qualitative standard of dental services, has led to an increase in patients' expectations, making it more difficult to justify therapeutic failure. In this context, the law n.124 of 2017, the Gelli-Bianco law, respectively intervened on the safety of care and on the responsibility of the healthcare worker; Law no. 219 of the same year on informed consent and anticipated treatment disposition; and numerous others that will be set out and exemplified below.
Role of Prosthetic Technology and Design in Improving Quality of Life of the Amputees and Challenges Ahead
Authors: Kumar Akshay , Vinita  , Kumar Rajeev

Prosthetic devices replace a missing body part lost through disease, trauma, or congenital disorder. The prosthesis is an external physical ‘medicine' that is applied to restore the movement, function, and cosmetic appearance of the lost body parts like a leg, hand, finger, ear, nose, etc. Prosthetists are the healthcare and rehabilitation professionals who assess, examine, prescribe, fabricate, and fit prosthetic devices to the amputees and also train them, if required, in acceptance of the prosthesis to the patient. The person who lost his or her limb through surgery in any form or having absence of limb by birth is known as an amputee. The technological advancement in the field of prosthetics has improved the quality of life of amputees in this century like nothing before and allowed them to interact with the wider world. Prosthesis plays an important role in returning the individual with limb loss to the pre-injury level of function. The future of prosthetic development appears to be promising.
The Decree-Law in the Pandemic Period
Authors: Aquino Caterina
Published: November 2022

The decree-law was introduced and evolved in the previous statutory system by means of a pure practice, due to the absence of any positive provision in this regard. This, however, determined a deep contrast in the doctrine of the time between those who considered decree-laws as illegitimate acts and those who justified their existence based on necessity as a source of law or based on a customary rule. The Constitution defines decree-laws as “provisional measures having force of law” adopted by Government, under its own responsibility, in extraordinary cases of necessity and urgency. Therefore, the fundamental prerequisite for the Government to adopt the acts in question is represented by the existence of extraordinary cases of necessity and urgency. In essence, the constitutional legislator anchored the adoption of decree-laws to the existence of the requirements of extraordinary necessity and urgency and established that the conversion law must be approved by Parliament within sixty days of the publication of the decree, under penalty of loss of effectiveness thereof from the beginning.

Published: November 2022

This study analyzes what leads one individual to choose a particular health care institution, its main factors of valuation, their level of satisfaction as users, and the factors of complexity in their choice process, in Portugal. This work will compare public and private institutions and characterize the users of both types of health institutions. The explanatory variables for choosing between public or private sector health care institutions are (1) complexity factors in accessing health care services, (2) individual's attitude toward the health, (3) quality of service and e-service, (4) effectiveness of treatment, (5) price fairness, and (6) institution's perceived quality. This information was collected through an online structured questionnaire and a quantitative methodology was applied. Results show that while overall service quality has a positive and significant influence on public and private health care institutions, choice difficulty shows a negative and significant influence.
Low Dose and the Conventional Dose Of 0.5% Hyperbaric Bupivacaine Produce Comparable Outcomes in the Lower Segment Caesarean Section. An Observational Study
Authors: Kumar Sudhir , Santha Neeta
Published: November 2022

Background:

Spinal anesthesia with 0.5% hyperbaric bupivacaine is an approved technique for lower segment cesarean sections. This study compared two different hyperbaric bupivacaine doses for spinal anesthesia in the lower segment cesarean section. We hypothesized that low-dose spinal anesthesia had similar outcomes as conventional doses of bupivacaine.

Methods:

This was a comparative observational study involving seventy healthy parturients who were posted for elective cesarean section. Patients were supposed to receive 0.5% hyperbaric bupivacaine and were divided into groups, low dose (LB-1.8 ml) and conventional-dose (HB-2.2 ml) group. The extent of motor blockade, sensory blockade, hemodynamic effects, visual analog scale for pain, and patient satisfaction were measured. The data were analyzed using the median and interquartile range for all parameters. A statistical package SSPS version 25.0 was used to do the analysis.

Results:

Hemodynamic stability was well maintained in both groups. Almost 100% of the patients in both groups achieved a grade 3 motor blockade in 8 min. T6 level of sensory blockade was achieved in 6 min by 100% of the patients. The low-dose group made a faster recovery compared with the high-dose group.

Conclusion:

Low-dose spinal anesthesia can cause similar hemodynamic and analgesic effects as the conventional-dose group. The only benefit of low dose spinal as compared with conventional-dose group was faster recovery from the anesthetic effects.

Published: November 2022

Background:

Probiotic organisms Lactobacillus reuteri UBLRU-87 and Bifidobacterium bifidum UBBB-55 were proven to be acting against the caries causing organisms.

Aims:

This study aims to evaluate the influence of Lactobacillusreuteri, Bifidobacterium bifidum and their blend on Mutans streptococci count in the saliva of children, and also to appraise the sustainability of their action.

Materials and Methods:

A randomized, double-blind and placebo-controlled study with 60 subjects (15 in each group) in 6–14 years of age group. The children consumed curd containing Bifidobacterium bifidum (UBBB 55, MTCC 5398) and Lactobacillus reuteri (UBLRu 87, MTCC 5403), and their blend once daily for 14 days. The control group received curd with no Probiotic in it. The saliva samples were collected just before the curd (T0) administration to establish baseline levels of mutans streptococci and after a day of the final consumption of the curd (T14). The follow-up samples at 21 days (T21) and 28 days (T28) after the baseline were also collected to know the sustainability of action probiotics on mutans streptococci if any.

Results:

Statistically significant reduction of mutans streptococci is observed in the group administered with Lactobacillus reuteri and the effect lasted up to a minimum of 21 days. Mixed cultures are seemed to be not effective against the oral microorganisms.

Conclusions:

The probiotic organism Lactobacillus reuteri in Indian curd is effective on salivary mutans streptococci, and the effect was sustained for some period after the administration.

Published: November 2022

Background:

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. GISTs originate from the interstitial cells of Cajal and are most commonly found in the stomach. Most available reports on GISTs in the Sub-Sahara Africa were in case reports and case series.

Aim:

To report our local experience and challenges in the management of GISTs in 33 patients in Lagos, Nigeria.

Methodology:

This is a descriptive study of adult patients of 16 years and above managed for GISTs at the Lagos University Teaching Hospital and some Lagos private hospital facilities between January 2015 and March 2021. Information on the patients' demographic characteristics, clinicopathological features, surgery performed, and postoperative complications were retrieved from the hospital's medical records for analysis. Data analysis was carried out using IBM SPSS Statistics for Windows, Version 23.0., Armonk, NY, USA: IBM Corp.

Results:

Thirty-three patients comprising 19 males and 14 females with a male: female ratio of 1.4:1 were included in the study. The mean age at presentation was 52.5 years. Abdominal pain (69.7%) and anemic symptoms (45.4%) were the principal modes of presentation. Abdominal computed tomography (CT) scan revealed stomach as the primary source of GISTs in 75.8% of patients. Forty-five percent of the patients had CT features of local organ invasion and 27.2% had features of metastasis. Surgical resection was feasible in 28 (84.8%) patients. Postoperative mortality was recorded in two patients with recurrent GISTs. Histological cell types were spindle cell (57.6%), mixed spindle and epithelioid (24.2%), and epithelioid (18.2%). Joensuu high-risk tumors (64. 3%) were the most prevalent in our series.

Conclusion:

Advanced-stage disease and features of anemia were hallmarks of GISTs among patients in this series. Surgical resection of GIST may be possible in some cases of advanced disease. Spindle cell types and high-risk GISTs were the most common pathological varieties in our patients.
