Size structure of a heavily fished benthic/demersal community by shrimp trawling in the Colombian Caribbean Sea
Authors: Gómez-Canchong Paúl , Quiñones Renato A. , Manjarrés Luis
Published: May 2023

The benthic and demersal communities in the Colombian Caribbean Sea (CCS) are heavily fished by the shrimp trawling fishery, which presents very high discard levels. Here, we conducted an analysis of the size structure of these benthic and demersal communities in the northern and southern zones of the CCS. Sampling was conducted onboard shrimp trawlers throughout an entire year. No significant differences were found in the size distributions of the two zones, among sites within southern ecoregions, or among the analyzed cruises. This homogeneity in size structure is remarkable since the zones analyzed possess very different species compositions and environmental conditions. The observed size structures were adequately described by non-linear distributions rather than the traditionally employed linear normalized biomass size spectra. It is hypothesized that the non-linearity is due to the effect of fishing and particularly, of discarding. This study emphasizes the need for a greater understanding of the impacts that trawl fishing has on community size structure and the applicability of this knowledge towards fishery resource management in ecosystems with high diversity.
Changes in the distribution density of locate, Thaisella chocolata (Duclos, 1832) (Gastropoda, Thaididae) as an indicator for predicting their reproductive events
Authors: Avendaño Miguel , Cantillanez Marcela , Oliva Marcelo , González María
Published: May 2023

For a population of locate, Thaisella chocolata, in La Rinconada, Chile, on a grid of 39 stations distributed along three 910 m-long transects at depths of 5 to 18.5 m, Moran and Morisita indices were used to evaluate whether density variations along the depth distribution are related to the stratification of larger sizes at the beginning of their reproductive process. Results indicate that before, during, and after forming reproductive aggregations, there is a T. chocolata increase in density in the shallow stratum (5 to 13 m). This finding is corroborated by the Moran index, which showed a greater autocorrelation in January-May, September-October, and January 2010, and by the Morisita index; thus, it is validated as a potentially easy-to-use indicator for assessing the reproductive process of this species. This index could also alert fishermen to the prevalence of reproductive aggregations in an area and that these aggregations should not be exploited as is currently the case to ensure the reproductive success of this species.
A Cross-Sectional Study of Obesity Determinants in Female Adolescents at the Gontor Islamic Boarding School for Girls
Authors: Mufidah Indahtul , Indarto Dono , Wiboworini Budiyanti
Published: May 2023

BACKGROUND: The prevalence of obesity in adolescents has increased worldwide for recent years. Body mass index (BMI)/age, waist circumference (WC), and waist-to-height Ratio (WHtR) are commonly used for assessment of nutritional status. Daily intake of fruits and vegetables and eating time of fruits inversely associated with obesity.

AIM: This study aimed to investigate the associations of daily intake of fruits and vegetables and eating time of fruits with obesity in female adolescents at the Gontor Islamic boarding school for girls.

MATERIALS AND METHODS: This cross-sectional study recruited 245 female adolescents from the Gontor Islamic Boarding School for girls, which were selected with a purposive sampling technique. They were eligible to follow this study if aged 12–16 years old and were healthy. Data of daily intake of fruits and vegetables were collected using the modified semi quantitative food frequency questionnaire. Anthropometric data consisted of body weight, height, and WC were measured using the standard measurements. Associations of individual variables with anthropometric parameters were analyzed using the Chi-square test. The multiple logistic regression tests were, then, used to analyze associations of independent variables and confounding factors together with BMI/age, WC, and WHtR with a 95% significant level.

RESULTS: The prevalence of overweight and obese was 31 and 2% among female adolescents, respectively. Intake of fruits and vegetables associated with BMI/age (p = 0.001), WC (p = 0.039), and WHtR (p = 0.024). Eating time of fruits had no associations with BMI/age (p = 0.207), WC (p = 0.551), and WHtR (p = 0.132). Inadequate intake of fruits and vegetables inversely associated with BMI/age (OR = 2.60; p = 0.002), WC (OR = 1.86; p = 0.047), and WHtR (OR = 1.92; p = 0.039).

CONCLUSION: Daily intake of fruits and vegetables inversely associates with BMI/age, WC, and WHtR but not for eating time of fruits among female adolescents in the Gontor Islamic Boarding School for girls.

Published: May 2023

A new subspecies of Leptidea sinapis from Northern Iran, discovered by means of DNA barcoding, is described as Leptidea sinapis tabarestanassp. nov. The new subspecies is allopatric with respect to other populations of L. sinapis and is genetically distinct, appearing as a well-supported sister clade to all other populations in COI-based phylogenetic reconstructions. Details on karyotype, genitalia, ecology and behaviour for the new subspecies are given and a biogeographical speciation scenario is proposed.
SARS-CoV-2-induced adrenal crisis in a patient with autoimmune polyglandular syndrome type 1: case report
Authors: Nyagolova Presiyana , Mitkov Mitko , Sapundzhiev Lyubomir
Published: May 2023

Autoimmune polyglandular syndromes (APS) are rare disorders characterized by the coexistence of endocrine and non-endocrine dysfunctions mediated by autoimmune mechanisms. Autoimmune polyglandular syndrome type 1 is defined as coexistence of chronic mucocutaneous candidiasis, hypoparathyroidism, and autoimmune adrenal insufficiency. Addison’s disease as the obligatory component is potentially life threatening.

Herein, we demonstrate a case of a 44-year-old woman with APS-1 (hypoparathyroidism, adrenal insufficiency, hypergonadotropic hypogonadism) and SARS-CoV-2-induced adrenal crisis. The patient presented with the typical manifestations of hypotensive shock, electrolyte disturbances of hyponatremia and hyperkalemia, and hypoglycaemia.

Our case report illustrates the increased risk of severe course of COVID-19 in APS-1 syndrome patients along with heightened exposure to medical complications. The case reinforced the significance of a timely diagnosis, appropriate treatment, and education of patients with such a rare condition like APS-1.
Expanding the functions of dental assistants in Bulgaria and perceptions about their role in the Bulgarian healhcare workforce
Authors: Ivanoff Chris S. , Andonov Bogomil , Hottel Timothy L.
Published: May 2023

Aim: The study queries a sample of dentists and dental assistants in Bulgaria about their understanding and perceptions of Expanded Function Dental Auxiliaries (EFDA). The study considers whether expanding the skillset of dental assistants to function in specific scenarios without personal supervision by the dentist may be a viable strategy to address various oral health inequities in the country.

Materials and methods: An anonymous survey was conducted among 103 practicing dentists and 100 dental assistants throughout the country. The questionnaire consisted of 20 questions that probed respondents’ understanding about the duties performed by EFDAs and their potential to increase productivity and efficiency of the dental workforce. Sociological (poll) and statistical (alternative analysis) methods were used in the survey.

Results: The majority of respondents were female. Most worked in the larger cities. One worked in a village. Most were ethnic Bulgarians and none were Roma, reflecting the racial imbalance in the national workforce. Two-thirds (67%) believed that dental assistants with appropriate training are capable of doing expanded dental procedures without personal supervision by a dentist. The majority (83.7%) believed that EFDAs could improve efficiency of a dental practice, while 58.1% indicated that with appropriate training, they could perform expanded duties as well as the dentist. However, only one third believed that EFDAs could increase practice output (38.9%); enhance the quality of the dentist’s work (37.4%); or decrease patient anxiety (31.5%). Though most respondents (78.3%) believed that a patient would not be receptive to an EFDA placing a restoration without personal supervision by the dentist, two thirds of respondents (66.5%) would like to see dental assistants trained to perform expanded duties otherwise reserved for dentists. Most respondents felt that EFDAs could help to build a well-functioning dental team.

Conclusions: Most respondents believed that EFDAs can benefit the efficiency of a practice, suggesting that Bulgarian dental professionals would respond favorably to enhancing the skillset of assistants with expanded functions. The study suggests they are skeptical about “general” versus “personal” supervision. EFDAs may potentially provide improved access by underserved communities, while building a more inclusive oral healthcare workforce reflective of the population.

Authors: Fortis Athanasios P. , Dedes Vasileios , Vergados Nikolaos , Panoutsopoulos Georgios I.
Published: May 2023

Aim: The present study presents the results of a modified tension band technique by surgically inserting K-wires to treat olecranon fractures.

Materials and methods: The modification includes inserting the K-wires from the olecranon’s upper tip and directing them to the ulna’s dorsal surface. Twelve patients (three males and nine females) from 35 to 87 years of age were operated for olecranon fracture. After the standard approach, the olecranon was reduced and fixed with two K-wires from the tip to the dorsal ulnar cortex. Then the standard tension band technique was carried out.

Results: The average operating time was 17.25±3.08 min. No image intensifier was used since the wires’ discharge was either visible, penetrating the dorsal cortex, or palpable through this area’s skin. The time needed for the bone union was six weeks. In one female patient, the wires were cut out. This patient showed a satisfactory painless range of motion (ROM) of the elbow but did not achieve full ROM. However, this particular patient had a previous removal of the radial head, and she spent some time in the ICU intubated. The modified technique used here is as stable as the classic operation, and it is safe since there is no risk of injuring the nerves and vessels of the olecranon fossa. There is less or no need for an image intensifier.

Conclusion: The outcomes of the present study are entirely satisfactory. However, many patients and randomized studies are needed to establish this modified tension band wiring technique.
Validated ion exchange HPLC method for the quantification of levothyroxine – a narrow therapeutic index drug – used for the treatment of hypothyroidism
Authors: Al Jamal Marwa , Al Bathish Malak , Gazy Azza
Published: May 2023

Drugs with narrow therapeutic index (NTI-drugs) have been defined by the FDA as drugs with small differences between therapeutic and toxic doses that might lead to serious therapeutic failures or life-threatening adverse drug reactions. Levothyroxine sodium pentahydrate (LT4), a synthetic T4 hormone used for the treatment of hypothyroidism (a condition where there is a hormonal imbalance in the thyroid gland that is responsible for the regulation of several physiological, metabolic, cardiovascular, and neurological processes). LT4 is designated by the FDA as a narrow therapeutic index drug and is available in the market in the form of very low dose pharmaceutical formulations ranging from 25 mcg to 150 mcg. This requires that the pharmaceutical dosage form should contain the exact labeled amount of the active ingredient, LT4, such that safety and efficacy are maintained. Therefore, it is necessary to develop an a precise, accurate and sensitive analytical method for LT4 quantification considering the treatment doses being in micrograms. In the present work, an ion exchange HPLC method has been developed and validated for the determination of LT4 as per ICH guidelines. The developed method was found to be simple, sepcific, precise and accurate. The low LOD and LOQ values allowed the quantitfication of the active ingredient in different pharmaceutical products qualifying the method to be applied in quality control assays.
Les effets de la Covid-19 sur la sécurité alimentaire des ménages ruraux de la zone des Niayes (Sénégal). Un changement des rôles de genre ?
Authors: Coulibaly Oumoul K. , Faye Cheikh
Published: May 2023

Les systèmes alimentaires sont caractérisés par des disparités sexospécifiques qui limitent leur résilience face aux chocs. De ce fait, les mesures prises par l’État du Sénégal pour limiter la propagation de la pandémie de la Covid-19 ont exacerbé les inégalités de genre dans les systèmes alimentaires du pays et, en particulier, ceux des Niayes. Mais en même temps, on observe une certaine capacité de résilience des femmes. Cette étude s’appuie sur des données d’enquêtes menées auprès de ménages agricoles et des acteurs des systèmes alimentaires de la zone des Niayes et produites par l’Initiative Prospective Agricole et Rurale (IPAR).

Published: May 2023

Cette étude a pour objectif d’analyser la contribution de l’assistance du Programme alimentaire mondial (PAM) qui a soutenu dix groupements agricoles de femmes dans la région du Poro, en vue de leur autonomisation progressive. Elle a mobilisé des données d’un échantillon de 371 femmes et sur la base d’entretiens avec les structures partenaires. Les résultats révèlent que l’assistance du PAM a favorisé la formalisation légale des dix groupements bénéficiaires. En outre, leur capacité agricole a été augmentée avec une meilleure dotation en matériels agricoles et une augmentation des superficies moyennes des cultures maraîchères. Tous les groupements ont désormais un compte bancaire. L’assistance du PAM a permis aux membres d’améliorer leur revenu en provenance des parcelles individuelles et d’acquérir la culture de l’épargne. Cela permet aux femmes de participer davantage aux dépenses des ménages, surtout sur les plans alimentaires et sanitaires. L’assistance aux groupements de femmes est une option alternative efficace pour la quête de leur autonomie et la sécurité alimentaire en milieu rural.

The Cities of Western Asia Minor and Rome: Local Agency in the Construction of Empire (133-44 BCE)
Authors: Jordan Bradley
Published: May 2023

Résumé Le présent article examine comment, à la fin de la République, les discours de l’administration romaine ont influencé les actions des poleis d’Asie Mineure occidentale et comment ces communautés ont répondu à l’hégémonie romaine. Je suggère l’idée que la diversité des discours administratifs romains a entravé l’apparition d’un modèle unique de gestion des relations avec les cités. En réponse, les poleis ont innové : bien que les décrets honorifiques restent un moyen important pour établir des relations réciproques avec des individus romains, la gestion des attitudes locales devint plus importante avec l’essor de la domination romaine. Les agents locaux ont aidé à construire l’empire en encadrant les discours romains pour un public interne.
Comment le gouvernement représentatif est devenu démocratique.
Authors: Lorrain Ludmilla
Published: May 2023

Que les seuls régimes politiques légitimes soient les démocraties représentatives contemporaines a acquis la force d’une évidence. Pourtant, à leurs origines, ces régimes représentatifs n’avaient pas vocation à être démocratiques : leurs fondateurs les avaient même imaginés pour prévenir l’émergence de formes de gouvernement démocratique. Partant de cet oubli, l’article propose de revenir sur l’histoire de l’association de la démocratie et de la représentation, des révolutions américaine et française à la première moitié du xix e siècle. S’attachant plus particulièrement aux usages de la notion de démocratie et de ses dérivés (« démocrate », « démocratique »), il s’attache à mettre en évidence la manière dont celle-ci, d’abord figure repoussoir dans l’ordre politique, est finalement devenue « maître-mot ».
La démocratie représentative en question(s)
Authors: Boyer Charles
Published: May 2023

La crise de la démocratie représentative nous amène à la questionner : est-elle vraiment démocratique ou s’agit-il d’un régime mixte ? Les représentants sont censés représenter le peuple, mais qu’est-ce que le peuple ? Comment sortir de l’âge de la défiance des citoyens envers l’élite au pouvoir ? Partant des analyses du citoyen de Genève pour qui l’exécutif a toujours tendance à subjuguer le législatif souverain, nous aborderons les enjeux actuels de cette crise qui se manifeste aussi par le « populisme » et la « démocratie sauvage » (les « gilets jaunes »). Ensuite, nous nous demanderons si la solution réside dans la « démocratie participative ». Peut-on en définitive espérer vivre dans une société harmonieuse, une « démocratie apaisée » ou bien faut-il admettre que le conflit est au cœur du social ?
La politique de frontière(s) de l’Allemagne à la lumière de la crise de la COVID-19 : un partage de compétences complexe

Published: May 2023

Il est intéressant d’examiner la répartition des compétences internes et externes de l’Allemagne fédérale en matière de politique de frontière(s) à travers la pandémie COVID-19. D’une part, il faut tenir compte des politiques sanitaires – principalement une compétence des Länder  – et de leurs impacts sur les frontières internes. De l’autre, les politiques de frontières externes relèvent de la compétence du Bund et impactent ses relations avec les États voisins lorsqu’un processus de « frontiérisation » est à l’œuvre. Enfin, il s’agit de savoir comment ses politiques de frontière(s) s’insèrent dans le cadre de l’Union européenne et de ses compétences communautaires en matière de gestion des frontières. Cette contribution montre d’abord comment le fédéralisme coopératif allemand commence pas être un obstacle pour une gestion coordonnée de la crise et aboutit à une « frontiérisation » interne entre Länder , puis comment il évolue vers un rééquilibrage des compétences entre le Bund et les Länder en matière de politique sanitaire ; puis comment, face à la « frontiérisation » externe, le fédéralisme coopératif allemand devient un atout pour une meilleure coopération transfrontalière pendant la pandémie et que l’UE devient un acteur de plus en plus important pour favoriser une coordination européenne en matière sanitaire et de politique des frontières.
Faculty as Learners: Neuroscience in Action
Authors: Patterson Barbara J. , Forneris Susan
Published: May 2023

Background:

Today's nursing education environment requires a contemporary approach to teaching and learning that consistently challenges nurse educators to develop their expertise and embrace advanced teaching techniques. The application of neuroscience principles is one such approach.

Method:

For this descriptive study, nurse faculty (N= 16) attending a 10-week faculty development course were recruited to participate in focus groups. Discussion topics included the influences of a program using neuroscience principles to enrich an educator's teaching practice.

Results:

Qualitative content analysis resulted in a model depicting a safe learning container contributing to a cognitive shift from teaching to learning in mind. Safe learning included communication of shared vulnerability, intentionality, and transparency. The shift required energy, risk taking, and time.

Conclusion:

The findings contribute to an increased understanding of how neuroscience principles are perceived through direct application by faculty using a novel approach to teaching and learning, thus advancing the science of nursing education.[J Nurs Educ. 2023;62(5):291–297.]
Phases and Transitions of Serious Illness: A Structure for Teaching Palliative Care
Authors: Harden Karen L. , Price Deborah M. , Bigelow April D. , Mason Heidi
Published: May 2023

Background:

Palliative care (PC) focuses on listening to patient preferences, goals, and values to help health care providers educate, support, and collaborate during challenging disease processes, demanding treatments, and difficult decision-making.

Method:

A recently developed Phases and Transitions Model for Serious Illness helps guide nursing students in initiating therapeutic conversations about PC. Each phase and transition shows unique characteristics of illness and treatment to clarify the importance of introducing PC for that phase. Interventions in education, support, and treatment help students guide patients and families through the trajectory of serious illness.

Results:

The Phases and Transitions Model for Serious Illness and PC interventions provide a clear and practical structure to educate and empower nursing students to engage in PC conversations.

Conclusion:

Nursing educators can integrate this new model to broaden the perspective of PC as an everyday nursing practice for patients who have a serious illness.

Published: May 2023

The approximate controllability of a class of fractional stochastic evolution equations (FSEEs) are discussed in this study utilizes the Hilbert space by using Hilfer derivative. For different approaches, we remove the Lipschitz or compactness conditions and merely have to assume a weak growth requirement. The fixed point theorem, the diagonal argument, and approximation methods serve as the foundation for the study. The abstract theory is demonstrated using an example. A conclusion is given at the end.

Published: May 2023

L-valine is a crucial amino acid that has rising market demand and numerous uses. It can be used to make specific nutrients, animal feed additives, cosmetic ingredients, and other things in the medical and agricultural fields. N-salicylidene-L-valine (NsLv) is attracting a lot of attention due to its unusual structure and enhanced catalytic and cytotoxic activities. Topological index is a numerical value which is associated with the molecular structure. It is very helpful to predict physio-chemical properties and Quantitative structure-activity relationship and Quantitative structure-property relationship modeling. We study the supramolecular chain (Sc) in the dialkyl tin of complexes 2, 3 and 4 of NsLv to better understand this structure and its topological index-related characteristics. Additionally, we compare topological indices and analyze how these structures relate to one another using concrete examples.
Prediction of the mechanical behavior of mortars incorporating phase change materials using data mining techniques
Authors: Cunha S. , Aguiar J. , Martins F.
Published: May 2023

Nowadays, it is imperative to reduce the energy bill in order to contribute to a more sustainable planet. In this sense, the use of materials that contribute to the energy efficiency of buildings is a very important contribution to achieve this goal. Mortars incorporating phase change materials (PCM) can make an important contribution to this end, due to its thermal storage capacity, increasing the energy efficiency of buildings. In this work several mortars with different PCM contents were developed, using different binders (cement, aerial lime, hydraulic lime and gypsum). The aim of this study was to apply data mining techniques such as artificial neural networks (ANN), support vector machines (SVM) and multiple linear regressions (MLR) to forecast the compressive and flexural strengths of these mortars at different exposure temperatures. It was concluded that ANN models have the best predictive capacity both for compressive strength and flexural strength. However, the SVM models have a flexural strength forecasting capacity very close to ANN models.

Situé dans une doline sur le Causse Noir, à une dizaine de kilomètres au nord-est de Millau, le petit abri de Combe-Grèze a d’abord été fouillé dans la seconde moitié du xxe siècle, puis a fait l’objet d’un récent retour sur le terrain par les auteurs du présent article. Ce site, occupé à différents moments de l’Holocène, a été largement mobilisé dans les scénarios de néolithisation des arrière-pays. Cependant, les travaux de terrain conduits depuis quelques années à l’extérieur de l’abri et un retour sur les collections anciennes permettent de nuancer nettement les interprétations anciennes, mettant notamment en évidence l’existence de nombreux problèmes de mélanges d’occupations. Ainsi, nous proposons ici une réactualisation des données disponibles concernant ce gisement, notamment pour ce qui concerne la nature des occupations, la chronologie, les productions matérielles issues des différentes occupations, les ressources exploitées et la précision du cadre paléo-environnemental.
Variations microclimatiques et effet de la végétation dans la ville aride de Ghardaïa, Algérie
Authors: Amieur Rachid , Saffidine Djamila Rouag , Weber Christiane
Published: May 2023

La caractérisation du climat urbain dans les villes chaudes et arides est essentielle pour comprendre les interactions des variables climatiques avec le bâti et la végétation. Les chaleurs estivales caniculaires constituent une contrainte extrême pour les citadins, en particulier la population à risque comme les jeunes enfants et les personnes âgées ou malades. La végétation contribue à améliorer le microclimat urbain de ces régions et est considérée comme un moyen de lutte contre les ICU (Ilots de Chaleur Urbains). Cette étude a pour objectif l’analyse des variations microclimatiques intra-urbaines et l’impact de la végétation dans la ville de Ghardaïa à travers une campagne de mesure in situ. Le comportement thermique des sites de mesures oscille entre ICU et IFU (Ilot de Fraicheur Urbain). L’étude a montré l’existence d’un « archipel » de chaleur à travers la ville. L’intensité maximale de l’ICU de chaleur est de 2.98°C. La température minimale nocturne est supérieure à 30°C, bien au-delà de la limite du confort thermique. Quant aux différences intra-urbaines, on note que la végétation produit un IFU maximal de 5.61°C. L’effet modérateur de la végétation durant le jour est dû principalement à l’ombre fournie par la canopée des arbres. Les sites végétalisés ne manifestent pas de différence significative d’humidité par rapport aux autres sites urbains. Il s’avère qu’un couvert végétal urbain plus dense et irrigué améliorerait davantage les conditions de confort en ville.
Vers un outil de restauration du sensible, le motif ambiant en trois temps caractérisation, expérimentation, mise en projet.
Authors: Toumadher Ammar
Published: May 2023

Cet article s’inscrit dans la volonté d’interroger le devenir urbain du point de vue d’une écologie dite du sensible. Nous tentons, en effet, de développer un spécimen opératoire en matière de caractérisation et de mise en projet prenant en compte l’ensemble des choses de l’environnement, qu’il soit construit ou non. Nous tentons également d’évaluer la portée opératoire de l’ambiance en matière de qualité et de durabilité des environnements urbains ou comment sauvegarder l’authenticité des ambiances d’un lieu tout en le projetant dans le futur à travers le développement de cet outil. Nous nous sommes proposés, par l’entremise des « motifs ambiants », d’avancer une modalité de travail qui traverse aussi bien les logiques de caractérisation que de projetation des ambiances tout en mettant en jeu les données environnementales. Nous l’avons mise en application dans trois situations différentes. La première en in situ, la seconde en in vitro et la troisième en utéro. La première étape se base principalement sur un objectif qui est celui de la caractérisation du vécu sensible. La deuxième est à l’entre deux de la caractérisation et de la projectuelle des ambiances et la dernière est de l’ordre de la conceptualisation et de la mise en projet configurée sous la forme d’une expérience pédagogique intersectorielle. Nous avons eu comme cas d’étude les quartiers de Capaci Piccolo et Capaci Grandi à Sousse. Ces quartiers sont nés vers les débuts du protectorat français et ont proliféré jusqu’aux années 60 en raison des différentes vagues d’immigration principalement sicilienne. À partir de l’indépendance (1956), le tissu social commença à se transformer. Aujourd’hui les quartiers sont exclusivement habités par des Tunisiens, alors qu’au début plusieurs cultures et nationalités y vivaient.
Estimation expédiée du risque érosif dans l’amont du bassin versant du Nahr el Kalb

Published: May 2023

La dégradation du sol par l’érosion hydrique est un phénomène naturel qui peut être amplifié par les actions anthropiques. Les conséquences de ce phénomène sont néfastes et peuvent nuire aux caractères intrinsèques du sol, et entraîner sa disparition dans certains cas. Pour cartographier l’aléa érosion dans l’amont du bassin versant du Nahr el Kalb, nous avons adopté une approche hiérarchique, nommée MESALES, qui combine les paramètres pondérés de l’érosion (occupation du sol, pente, érodibilité du sol et climat) dans un Système d’information géographique (SIG). Afin de tenir compte des spécificités du milieu, l’érodibilité des sols a été calculée à partir de l’équation de Wischmeier et Smith (1960 ; 1978). Le bilan de ce travail montre le rôle prépondérant du couvert végétal. 67 % du périmètre d'étude subit une forte et très forte érosion, il s’agit essentiellement des secteurs ayant un couvert végétal dégradé ou en étant dépourvus. La précision globale du modèle et l'indice Kappa qui en sont ressortis sont estimés respectivement à 84 % et 80%.
Determinants of Foreign Direct Investment and the Advantages Theory
Authors: Li Shijie
Published: May 2023

This study reviews three classic international business theories and some related empirical studies to identify the gaps in the literature and suggest future research directions. In international business studies, most analyses on the determinants of FDI are centered on three concepts of firm-specific, internalization, and location advantages according to the monopolistic advantage theory, internalization theory, and OLI paradigm. These three advantages determine whether a firm will internationalize, how it will enter foreign markets, where it will locate in the host country, and how it will perform in a foreign market. However, These theories are set up with the premise of firm-specific advantages and cannot be used to explain the phenomenon of emerging market multinational enterprises, which have emerged in large numbers in recent years. Simultaneously, these theories, which focus on manufacturing, need to be used to explain the internationalization of the service industry in-depth and with greater relevance.
Progress in muscle research through the international congress of neuromuscular diseases (ICNMD): a narrative review
Authors: Angelini Corrado
Published: May 2023

Progress in muscle research has been through different phases over the past decades. Here are reviewed the advances presented at the International Congresses of Neuromuscular Diseases (ICNMD). In the ‘60 to ‘80 muscle physiology and interpretations of muscle biopsy were the major focuses, diagnosis of muscle disorders was advanced utilizing histochemical, and ultrastructural techniques, and the focus of first to IVth ICNMD was prevention and Muscle Disorders classification as major issues. After that from ‘80 to 2000 muscle neuromuscular junction (NMJ) immunology, biochemistry, molecular biology , therapeutic trials, and genetics were the major developments and represented the focus of research in following ICNMD from the Vth to the Xth. From 2000 to 2020 personalized medicine,genotype-phenotype correlation, and the use of DNA/RNA profiling , Imaging was developed and represented substantial signs of progress that were presented in ICNMD XIth to XVIIth. The future is evolving toward a major involvement of the pharmaceutical industry with new drugs and gene-delivered therapy, the use of biomarkers and robotics as well as of artificial intelligence, both for interpreting morphology, DNA, and imaging diagnostic, and such developments will be reflected in research presented in future Congresses.
Do weak stationary magnetic fields affect the perceived astringency of red wine?
Authors: Rowcliffe Stephen Wesley
Published: May 2023

To investigate claims that products containing weak stationary magnets can reduce the astringency of tannic red wine, a double- blind randomized trial was carried out, in which 96 paired tastings were conducted of magnetized and non-magnetized samples of a young Nebbiolo. The data showed no association between reported differences in astringency and actual difference in the magnetic treatments given to the wine (χ2=0.135, degrees of freedom=1, P=0.71). This study confirms an earlier work that magnets have no observable effect on red wine.

Background:

Snakebite is an acute life-threatening and time limiting medical emergency. Alternative and traditional methods of cure are barriers to early treatment which results in considerable delay in coming to the hospital. This study was done to assess the clinical profile and to identify long-term perspective of snake bites in patients who presented to the hospital beyond 6 h of snake bite.

Methodology:

This descriptive study was conducted over 18 months that included 45 patients with alleged history of snake bite of which 15 had delayed presentation, 6 h after snake bite. A detailed history, clinical examination and investigations were monitored for any complications during treatment and follow-up to look for delayed complications.

Results:

The clinical profile and outcome were different among patients presenting beyond 6 h and within 6 h, cellulitis (46.66% vs. 33.33%), bleeding manifestations (46.66% vs. 50%), neurological manifestations (33.33% vs. 33.33%), AKI (33.33% vs. 16.66%), respiratory failure requiring ventilatory support (33.33% vs. 10%), and mortality (20% vs. none). Delayed complications observed in patients with delayed presentation on long-term follow-up were ulceration including knee amputation, chronic kidney disease, psychiatric disturbances, and musculoskeletal symptoms.

Conclusion:

The acute complications were significantly higher with delayed presentation and delayed complications that are often overlooked which contributes to significant morbidity and suffering. The general population needs to be educated regarding the available treatment strategies and significance of seeking early medical attention for better treatment outcome and to reduce morbidity and mortality both short term and long term.

Authors: Madhavi R. Bindu , Hanumanthappa A. R.
Published: May 2023

Background:

Surgical site infection (SSI) is the most common type of hospital-acquired infection-causing public health problems. The study was undertaken to know the aerobic bacteriology of SSI with special reference to the detection of metallo-beta-lactamase (MBL) and AmpC beta-lactamases among Gram-negative bacilli.

Methods:

The present cross-sectional study was conducted in 140 patients clinically suspected to have SSIs. Samples were collected from patients after considering inclusion and exclusion criteria.

Results:

Out of 85 Gram-negative bacilli, 9 isolates (10.6%) were Amp C producers. Out of a total of 85 Gram-negative bacilli, 3 isolates (3.5%) were MBL producers. Two isolates of Pseudomonas aeruginosa and 1 isolate of Acinetobacter spp. were positive for MBL production. In the present study, MBL production was seen in 3.5%, of Gram-negative bacilli.

Conclusions:

Early identification of such resistant strains is important to plan the appropriate antibiotic therapy. Strict infection control practices and judicious use of available antibiotics are essential to prevent the emergence of multidrug-resistant strains.

Published: May 2023

Background:

Schwannomas are neoplasms that are rarely found in the sinonasal tract and pterygopalatine fossa (PPF). The objective of this study is to evaluate the schwannoma in the sinonasal tract and PPF including its effectiveness of endoscopic surgical excision of the lesion.

Methods:

This retrospective study was done between March 2018 and April 2022. There were nine cases of benign schwannomas found in the nasal cavity, the nasal ethmoid and the PPF. All patients had undergone endoscopic endonasal removal of the tumour.

Results:

All the patients successfully underwent endonasal endoscopic excision of the schwannoma from the sinonasal tract and PPF. Out of nine patients, one showed recurrence after 1 year during follow-up check-ups. None of the patients showed any major vascular complications during surgery. At follow-up, one patient presented with a persistent sensory deficit in the facial area.

Conclusions:

The endonasal endoscopic approach for schwannoma at the sinonasal tract and PPF is a safe and effective method for biopsy and treatment. This approach is highly effective for visualisation and has the potential to reduce complications. Pre-operative imaging is an important step before successful treatment by endoscopic endonasal removal of the schwannoma.

ABSTRACT

Objectives:

The goal of the current research was to assess marginal sealing abilities of 2 commercial pit and fissure sealants.

Materials and Methods:

A total of 30 premolar teeth were equally classified into 2 groups: Group A-application of Embrace-WetBond sealant and Group B-application of Fissurit F, Voco sealant. After sealant placement, samples were preserved in artificial saliva for 48 hours prior to thermocycling. Later, samples were submerged for 24 hours in a 2% methylene blue solution. The amount of microleakage based on the quantity of dye penetration at interface between the tooth substance and sealant was compared under an optical stereomicroscope. The obtained data were statistically analysed for the dye penetration scores in both groups.

Result:

It was observed that 8 samples from Group A (53%) had no dye penetration (Grade 0), whereas 4 samples from Group B (26%) showed Grade 0 penetration. In 5 out of 15 samples (33%) from Group B, the dye penetration was the greatest (Grade 3; P = 0.012).

Conclusion:

It was concluded that Embrace-WetBond had lesser microleakage compared to group 2-Fissurit F, Voco sealant.

ABSTRACT

Background:

HNSCC (head and neck squamous cell carcinoma) is a serious global health problem, with estimated more than 550,000 new cases and 300,000 deaths annually. More than 90% of these malignancies are oral squamous cell carcinoma (OSCC).

Materials and Methods:

Patients selected were asked to fill the detailed structured case history proforma and thorough clinical examination, structured, pre-designed, pre-evaluated (UW-QOL) UW Questionnaire version 4 on quality of life (QOL) of oral squamous cell carcinoma patients containing thirteen subjective questionnaires and three global questionnaires. All the patients of OSCC after one month (1 month) of radiation and chemotherapy were assessed for quality of life by questionnaire.

Result:

Post-treatment QOL assessment of OSCC patients reveals a number of problems such as chewing, swallowing, saliva, lack of activity, and mood disturbances. Preoperative clinical features including tumor site, tumor stage, and extent of mouth opening have a significant impact on post-treatment problems in different ways.

Conclusion:

The need to balance clinician’s need and use of health-related quality of life (HRQOL) data against patient’s burden should be considered in the selection process.
A Cross-Sectional Evaluation of Dental Professional’s Knowledge of Locally Delivered Antimicrobial Agents and their Application in Periodontal Practice

Published: May 2023

ABSTRACT

Introduction:

Dentists must employ locally delivered antimicrobial agents (LDAs) in a way that is in line with current recommendations from the scientific literature and the guidelines set by professional organizations. Considering the dearth of research on this topic, it is not known what strategies are adapted when using LDAs in their periodontal practice. So, the purpose of this research was to investigate how LDAs are utilized by dental professionals in their distinct periodontal practices.

Materials and Methods:

This cross-sectional study used a closed-ended questionnaire. Dental professionals received electronic copies of the eight-item questionnaire. The questionnaire assessed the relevance of LDAs, how frequently they are used, which ones are used most, the number of patients who receive them, their understanding of pharmacological activities, and their knowledge of current treatment guidelines. The questionnaire’s validity and reliability were evaluated before being presented to participants. Using the Statistical Package for the Social Sciences (SPSS), the input was analyzed.

Results:

A total of 120 dental professionals, with an average age of 34.7 years, answered the questionnaire. Half of these individuals have no history of ever using LDAs. The most frequent LDA used in its different forms was chlorhexidine gluconate (CHX), followed by tetracycline. The majority of participants placed LDAs (80%) in less than 10 patients. Less than half acknowledged the different LDAs and their pharmacological activities. Not even 70% of clinicians were up-to-date on the current European Federation of Periodontology (EFP) guidelines. None of the participants discounted the significance of LDAs in periodontal care.

Conclusion:

Dental professionals regard LDAs as essential to periodontal therapy. Yet, they lacked knowledge about general, pharmacological, and clinical aspects. The patient experience with LDAs was limited by an inappropriate deployment pattern.

ABSTRACT

The objective of this study is to compare retention capacity of mandibular implant-supported overdenture with all zirconia, zirconia–PEEK, and all PEEK telescopic attachments. Sixty acrylic resin models of mandible were used. Telescopic attachment system was made up of all zirconia, all PEEK, and zirconia–PEEK. Evaluation of retention force was done using universal testing machine. Obtained data were statistically evaluated. Highest initial force value was obtained with zirconia–PEEK group. All PEEK and zirconia–PEEK groups showed significantly decreased final retention values in comparison to their initial values. Zirconia can be regarded as the material of choice for telescopic crown, whereas polyetheretherketone and zirconia–PEEK telescopic crowns showed retention loss over a period of time.

ABSTRACT

The present study was conducted to assess stress distribution around dental implants based on the all-on-four treatment concept. The finite element analysis (FEA) models comprised cancellous bone covered with cortical bone. Four dental implants were placed in two different designs. In model 1, the four implants were placed parallel to each other, whereas, in model 2, the all-on-four concept was followed. The vertical and lateral loads of various values were applied, and stress was evaluated. In model 2, the least stress was observed in both lateral and vertical loading in the peri-implant region. The all-on-four concept proved to be beneficial in reducing the stress around dental implants, thereby reducing the treatment cost.
