Digging Cognition: Is it Possible?
Authors: Wadley Lyn
Published: September 2023

Many archaeologists consider that symbolic behaviour is the key to a satisfactory definition of modern cognition, but items thought to embody symbolism are rare in the archaeological record and interpretation of their meaning is often theoretically problematic. Cognitive attributes that psychologists use, such as the ability to switch attention between tasks, analogical reasoning, response inhibition and multi-tasking seem more appropriate for study because they are evident in everyday tasks that are most often represented in the past. Technological data are abundant archaeologically and proxies derived from everyday technology can thus be used to interpret ancient cognition. Items of material culture can yield information about the minds of their makers because certain tasks cannot be performed without appropriate cognitive attributes. Theoretical ways of recognizing complex cognition include establishing which steps in technical processes cannot be undertaken without attributes of complex cognition such as multi-tasking and analogical reasoning. Bridging theories between archaeological data and interpretation of cognitive abilities are essential to the methodology. It also benefits from the application of scientific method and also supporting data retrieved from replication experiments that enable testing of hypotheses.
Développement ontogénétique de la cognition humaine : champs de recherche, méthodes et perspectives
Authors: Rat-Fischer Lauriane
Published: September 2023

Dès son origine, l’étude du développement de la cognition humaine d’un point de vue ontogénétique, c’est-à-dire de la naissance jusqu’à l’âge adulte, a été soumise à des défis théoriques et méthodologiques. Cette revue de littérature propose un aperçu de la multiplicité des méthodes et des approches permettant l’étude du développement de la cognition humaine, ainsi que de leurs limites respectives. Dans un premier temps, nous exposerons les méthodes classiquement utilisées en psychologie du développement pour l’étude de la cognition chez le bébé et chez le jeune enfant. Dans la seconde partie de cet article, nous décrirons comment certains travaux de la psychologie du développement se sont orientés vers les problématiques liées à l’étude de l’évolution de la cognition humaine. Enfin, dans un troisième temps, nous nous intéresserons aux progrès scientifiques qui ont mené à l’apparition d’un nouveau champ de recherche intégrant l’intelligence artificielle : la robotique développementale. Nous conclurons cet article par une discussion sur les perspectives et enjeux pour l’étude du développement de la cognition humaine.
Les « sens » de la mémoire

Published: September 2023

L’approche incarnée et située prédit des interactions directes entre les traitements sensorimoteurs et cognitifs. Cet article présente les arguments en faveur de telles interactions en se concentrant sur le fonctionnement sensoriel et mnésique chez le jeune adulte, ainsi que sur la question des mécanismes qui sous-tendent ces interactions. Ces mécanismes incarnés et situés s’accompagnent non seulement d’interrogations épistémologiques fondamentales sur la notion de représentation et de modularité des fonctions cognitives, mais aussi d’enjeux d’ordre appliqué, en particulier lorsque l’approche incarnée et située est appréhendée selon un critère de fécondité épistémique. Cette fécondité est illustrée avec l’étude du vieillissement cognitif, car le vieillissement est marqué par des changements concomitants dans le traitement sensorimoteur et mnésique.
Hypnose, mémoire et cognition incarnée

Published: September 2023

The Cognitive Hypnosis, Memory and Embodied Cognition. Among embodied cognition approaches, a growing number of studies has highlighted the close relationships between the processes that underpin memory and sensory-motor processes. Among these approaches, the Act-In model (Versace et al., 2014) proposes that during a living experience, memory traces automatically emerge through the dynamic activation and integration of sensory and motor dimensions of that experience. During a later living experience, the situation reactivates these previous traces, so that the different dimensions of the present and the previous experiences become integrated. In this model, the perception of the present situation can thus be influenced by previous traces, and conversely, the previous traces can be influenced by the present perception. In parallel to the development of embodied approaches of cognition, the issue of the relationships between the body and the memory has also been discussed among hypnosis specialists. Indeed since the rising of hypnosis at the end of 18th century up to its nowadays practice, notably impacted by Milton Erickson, several important hypnosis methods have been characterized by their use of memory to reach therapeutic goals for patients with physical or psychic problems. For instance, age regression notably consists in proposing to the patient a “revival” of a moment of his life, in order to solve a present problem or to modify a present perception. These hypnosis methods using memory are common and their effects are often described in literature : several specific research domains, as false memory created consecutively to an age regression, brought clinical and experimental studies articulating memory and hypnosis. However, these methods are presently explained by no consensual conceptual nor theoretical model. Moreover, the processes underpinning this kind of phenomenon are not yet well understood. Through a pluridisciplinary reflection, the present paper has two goals. First, it aims at discussing the heuristic relevance of the Act-In model to understand why hypnosis methods based on memory produce specific and observable effects. Second, it aims at discussing to what extent hypnosis might allow the development of new methods to explore the dynamic and embodied dimension of human memory.
Education TV's website that guides today's student community

Language was needed to communicate with one another when human society emerged on earth. In ancient times, language was understood through gestures and sounds. Human society brought language into written form to continue civilizing. That script was also transformed into hieroglyphics, syllables, scripts, etc., and changed to the scriptwriting system we use today. We needed a medium to communicate with distant people. In the early days, it was also communicated by writing. It wrote on barks, clay tablets, pottery tiles, animal skins, and clothes. As the knowledge of human society expanded, so did his discoveries. After the discovery of paper, mankind wrote everything on paper as the medium of letters. Human society communicated through it. As the time of writing on paper gradually became obsolete, writing on a computer became new with the development of technology. There was only a letter to contact those far away that day. The telegraph came because of the technological revolution. The phone arrived. The radio came on. Television also came. As a result of the information technology revolution, the internet, a medium that surpassed all this, came into being. The website swallowed up everything that had previously been used for communication separately. Do you want to send a letter to someone? Want to talk to someone in some corner of the world? Want to listen to the radio? Even if there is no television at all, do you want to know what's happening in other countries? The website has been transformed into a time mirror that shows everything. Various literature is being created in Tamil on such a website. Originally created for the communication of various types of information, the website today has a deep footprint on all platforms. It is also doing the work of educating the students. No one learns anything at birth and comes back. Everyone learns language, mathematics, science, society, etc. during their student days. Today, websites have created a situation where even going to school can be done from home. In this context, the Tamil Nadu Government's Education TV, which broadcasts educational programmes for students, also has a website. This article aims to examine whether the website has similar functionalities for today's student community.
Professional socialization of midwives in the first year of work in hospital wards
Authors: Tomaszewska Zuzanna , Doroszewska Antonina , Fry Jane
Published: September 2023

Abstract: Introduction and objective: The first experience of entering a profession has a huge impact on an employee’s later life. They affect motivations for development, relationships with co-workers, and in the medical sector will directly translate into patient safety and well-being. When midwives take up their first job, they face challenges and obstacles related not only to their inexperience, but also to communication in teams, the implementation of which requires time and commitment on both sides–the implementing and experienced employee. Material and methods: The aim of the research presented here was to identify difficulties related to communication in midwifery teams, especially at the level of experienced–inexperienced midwife and to find out the opinions on mentoring as a way to support in the first months of work. The study was conducted by means of group interviews. Three interviews were conducted with a total of 11 midwives with 1-2 years of professional experience working in hospital wards in three Polish cities. Results: In the participants’ statements, three issues were singled out as the most important issues raised related to the difficulties of the first months at work: the organization of the induction system, the sense of mutual trust in the team of co-workers and the inequality of wages. Conclusions: A sense of security resulting from mutual trust and acceptance is crucial for young midwives entering the profession. A factor conducive to a smooth socialization process to work is a properly functioning mentoring system. Communication difficulties that cause division in teams, may be related to the inequality of salaries, resulting from the disparity in the level of education of midwifery staff in hospital wards.

Authors: Lipińska-Grobelny Agnieszka , Ozga Klaudia
Published: September 2023

The aim of this study was to evaluate the relationship between being stressed in the work environment and different leisure activities, also whether specific temperamental characteristics compatible with Regulative Theory of Temperament by Strelau - emotional reactivity and activity – influence the connection between above mentioned variables in a major way. The study included 124 professionally active participants with age ranging from 18 through to 65 years old. It was conducted through paper-pencil method in stationary mode using three tools: Formal Characteristics of Behaviour – Temperament Questionnaire Revised Version, Subjective Work Assessment Questionnaire and Free Time Spending Questionnaire. Results showed that as the level of stress at work increases, relaxation and physical activity decreases, as well as activity, while emotional reactivity increases. At the same time, the higher the relaxation and physical activity, the higher level of activity and the lower emotional reactivity. Moreover, those two temperament traits can modify the relationship between leisure and workplace stress.
Young women’s transition to motherhood: relations with partners and visions of motherhood
Authors: Rzechowska Ewa
Published: September 2023

The study uses a processual approach drawing on the modern definition of reproductive health, which recommends individualised measurements of populations. A case study analysis is performed to build a comprehensive empirical model of transitions in young women’s relations with their partners and visions of motherhood, which are critical to understanding young adult females’ reproductive health. Data necessary to reconstruct the setup of individual life paths were collected using exploratory interviews and questionnaires and analysed in the framework of the Strategy of Process Transformation Reconstruction (PTR). The PTR strategy is an innovative tool that combines the qualitative analysis of individual cases and C4.5 Quinlan’s algorithm to make generalisation.

The empirical model of internally diverse types of relationships and visions of motherhood formed by young Polish women consists of a sequence of variants showing the evolution of the character, and ways of building and integrating intimate relationships with motherhood. The model can serve as a matrix for creating analytical categories that can be used to describe young women’s relations with their partners and visions of motherhood, construct psychological scales, and plan therapeutic procedures.
Maternal expectations and paternal self-efficacy as factors associated with the occurrence of depressive symptoms in parents after childbirth.
Authors: Kossakowska Karolina
Published: September 2023

Depressive symptoms with onset after the birth of a child can affect both parents. The aim of the presented study was to determine whether fathers and mothers differ in terms of postpartum depression symptoms and such variables as the sense of parental competence and the prenatal expectations of discrepancy, and whether these variables are related to the occurrence of postpartum depression symptoms in women and men. 271 people, including 165 women and 106 men, who became parents in the last 12 months, were examined. The Edinburgh Postnatal Depression Scale (EPDS), Parental Sense of Competence Scale (PSOC) and Prenatal Expectations Scale (PES) was used. The results indicate differences between mothers and fathers in postpartum depressive symptoms, parental competencies, and prenatal expectations discrepancy as well. While maternal depression symptoms are determined by failure to meet prenatal expectations, depressive symptoms in new fathers are associated with a low sense of paternal competence.

ENSURING INFORMATION PROTECTION OF DIGITAL COMMUNICATION SYSTEMS BASED ON FUNCTIONAL RESOURCES OF THE PHYSICAL AND CHANNEL LEVELS A.O.
Authors: Шорин А.О. , Бокк Г.О.
Published: September 2023

Система защиты информации в современных сетях связи предполагает наличие сквозного контроля работы на уровнях от физического (L1) до прикладного (L7). В статье показаны возможности существенного упрощения взлома с последующим доступом к служебной и пользовательской информации сети, если работа на физическом и канальном (L2) уровнях не полностью контролируется сетевым администратором. Причем от такого взлома не предохраняют даже методы шифрования, применяемые на сетевом (L3) и более высоких уровнях. Путем неконтролируемых воздействий создаются условия для последовательного взлома защиты от уровня к уровню вверх, подобно «вскрытию матрешки». С другой стороны, отсутствие доступа к уровням L1 и L2 у взламывающей стороны делает при определенных усилиях чрезвычайно трудным процесс несанкционированного доступа к информации верхних уровней современных сетей даже в случаях отсутствия на них шифрования. Возможности противодействия взлому рассмотрены на примере обобщенной проприетарной системы широкополосного доступа.

The information security system in modern communication networks assumes the presence of end-to-end control of work at the levels from the physical (L1) to the application level (L7). The article shows the possibilities of significantly simplifying hacking with subsequent access to service and user information of the network, if the work on the physical (L1) and channel (L2) levels is not fully controlled by the network administrator. Moreover, even encryption methods used at the network (L3) and higher levels do not protect against such hacking. By means of uncontrolled influences, conditions are created for the consistent hacking of protection from level to level up, like the “opening of a matryoshka doll”. On the other hand, the hacking party’s lack of access to the L1 and L2 levels makes, with certain efforts, the process of unauthorized access to information of the upper levels of modern networks extremely difficult even in cases where there is no encryption on them. These antihacking capabilities are considered using the example of a generalized proprietary broadband access system.

Рассматривается задача повышения помехозащищенности многофазных CDMA последовательностей за счет уменьшения количества фаз и динамического диапазона. Многофазные CDMA последовательности получены суммированием фазных информационных ортогональных последовательностей. Уменьшение количества фаз и динамического диапазона достигается за счет преобразования каждого элемента многофазной CDMA последовательности в фазный элемент групповой последовательности с модулем, выбранным из возможных вариантов целочисленных модулей. Для полученных в результате такого преобразования групповых последовательностей при различных количествах абонентов с помощью компьютерного моделирования определена зависимость энергетического выигрыша от изменения количества фаз относительно передачи двоичных информационных сигналов.

The paper considers the problem of increasing the noise immunity of multiphase CDMA sequences by reducing the number of phases and the dynamic range. Multiphase CDMA sequences are obtained by summing phase information orthogonal sequences. The reduction in the number of phases and dynamic range is achieved by converting each element of the multiphase CDMA sequence into a phase element of the group sequence with a module selected from possible integer modules. For the group sequences obtained as a result of such a transformation for various numbers of subscribers, using computer simulation, the dependence of the energy gain on the change in the number of phases relative to the transmission of binary information signals is determined.

Published: September 2023

In recent years, there has been an increasing interest among food industry producers for functional foods. In this context, the study aims to isolate new lactic acid bacteria strains with probiotic potential that could further be used to obtain valuable metabiotics with good technological potential and health benefits. In the current study, twenty-nine newly LAB strains were isolated from various natural sources, including artisanal cultures (like, kefir grains and kombucha membrane), and selected through fermentation potential on unconventional plant-base substrates, consisting red lentils flour, red potato peel powder, and okara. The strains identified using 16S rDNA sequencing, as Lacticaseibacillus paracasei (encoded BL13, BL80, BL87) and Lactiplantibacillus plantarum (encoded BL21) were further screened considering their in vitro probiotic properties. The safety assessment evaluation highlighted that Lacticaseibacillus paracasei (BL13) and Lactiplantibacillus plantarum (BL21) selected as performant strains have antimicrobial potential against Escherichia coli and Staphylococcus aureus, being also susceptible to tetracycline, chloramphenicol and ampicillin. Furthermore, Lactiplantibacillus plantarum (encoded BL21) proved good adhesion properties on the HT-29 cell line. These strains are new promising probiotic starter cultures candidates with approachable potential to be used for obtaining functional food and ingredients through fermentation processes, that could offer health benefits.

Published: September 2023

Cinnamic acid is a phenolic compound with the potential to act as a natural antioxidant. Cinnamic acid esterification can be performed by adding a long-chain alcohol to one of its hydroxyl groups to improve its antioxidant activity. In this study, cinnamic esters were synthesized in an enzymatic membrane reactor (EMR) and were carried out continuously. This study aimed to determine the optimum conditions for the synthesis of cinnamic esters using various types of alcohols (e.g., butanol, hexanol, and octanol) as alkyl group donors and the impact of the esterification on the antioxidant activity. The continuous synthesis of cinnamic esters with TL IM lipozyme as the biocatalyst had the highest conversion (20.91%) with 1-butanol as the alkyl donor, in a synthesis strategy of a 12-h batch followed by continuous operation with a residence time of 9 h. The resulting ester increased the antioxidant activities by 2.18 and 3.85-fold, respectively based on the DPPH and FRAP assays.
Maillard reaction products between whey powder and water-soluble tempeh protein extract: membrane-based fractionation

Published: September 2023

Whey powder, an industrial by-product, has the potential to be transformed into functional ingredients using the Maillard reaction. In this study, this chemical reaction occurred between whey powder and tempeh protein extract, resulting in increased antioxidant activity. This study aimed to isolate the Maillard reaction products (MRP) with the best antioxidant capacity using an ultrafiltration (UF) membrane by considering the fouling phenomenon that occurred on the membrane surface and critical flux for the filtration. MRP exhibited an antioxidant capacity of 0.09 mg ascorbic acid equivalent antioxidant capacity/mL, and the fractionation using a 5 kDa MWCO PES membrane showed the highest antioxidant capacity in terms of free radical reduction and metal chelating mechanisms. During MRP filtration, fouling on the membrane surface was observed, which could be attributed to the cake filtration model. The critical flux value was determined to be 4.23 LMH with a corresponding pressure of 0.75 bar. A long-term filtration below the critical flux showed stable performance, but filtration above the critical flux resulted in significant fouling. The permeate antioxidant IC50 value was 4.25 mg/mL. Based on the LC-MS analysis, 1,4-dihydroxy-2-methyl-anthraquinone and ilexin II were found as the potential contributors to the antioxidant activity of MRP. In summary, our study demonstrates that fractionating MRP using UF membrane-based filtration is an effective method for isolating MRP with high antioxidant capacity. Our findings also shed light on the critical flux value and fouling phenomenon during MRP filtration, which are important considerations for scaling up the production process.
Influence of edible termite flour supplementation on the functional and pasting properties of maize ogi powder and the sensory acceptability of the gruel
Authors: Awoyale Wasiu , Racheal Fadeni Funmilayo
Published: September 2023

Ogi is a traditional staple food rich in carbohydrates but low in protein. The inclusion of termite flour (TF) apart from increasing the protein content could affect other attributes, thus, the need for this study. The functional and pasting properties of the Ogi samples and the sensory evaluation of the gruel, produced from the blends of Ogi powder (OP) (50-100) with termite flour (TF) (10-50), were evaluated using standard methods. The result showed that adding TF to the OP slightly reduced the water (WAC) and oil absorption capacity (OAC), and increased the bulk density, swelling power, and all the pasting properties (except the peak time and pasting temperature) of the Ogi samples. The overall acceptability of the gruel from the 100g OP (control sample) was not significantly different from that of the 75.0:1.7 and 75.0:30.0 grams of the OP and TF blends. Consequently, the inclusion of the TF in the OP may not only increase the nutritional composition as reported by other researchers but produce an acceptable Ogi gruel of good pasting properties and comparable functionality to that of the control sample, which could be achieved by blending 75.0g of OP with either 1.7 or 30.0 g of TF.

The use of pectolytic enzymes to clarify the white grape juice is a simple and economical solution for positively influencing the subsequent technological steps. The positive effects refer to improving the filterability of the final wine, the behavior of the wine during the stabilization treatments, and, most important, wine quality. The experimental study consisted of treating the grape juice with Zymoclaire Pro Ice for the maceration and extraction steps, and Zymoclaire CC Plus for the clarifying step. The evolution of grape juice clarification parameters such as turbidity, oxidation stability, and the dynamics of the alcoholic fermentation were monitored. The study revealed that after 24 h of treatment, a higher volume of clarified grape juice was achieved. The volume of clarified grape juice was 55% in the control samples, while in case of the sulfited grape juice, clarified with maceration and extraction enzymes or with clarification enzymes, reached 72% and 84%, respectively. The optimal turbidity levels of the juice’s enzymatic clarifying stage were reached after 24 hours in case of both enzyme treatments. The comparative analysis of the physicochemical parameters did not reveal significant differences between samples regarding free and total SO2 contents, potential alcoholic concentrations, volatile acidity, and residual sugars. Also, the enzymatically treated samples were the most appreciated from a sensory point of view. In conclusion, the results revealed that the enzyme tested in these experiments showed high efficiency in grape juice clarifying.
Caracterización genética del caballo Polo Argentino mediante el análisis de datos genealógicos y de polimorfismos de nucleótido simple

Published: September 2023

El objetivo general de esta tesis fue evaluar la variabilidad y estructuración genética de la raza equina Polo Argentino, utilizando datos genealógicos y genotípicos obtenidos con un microarray de SNP. Se utilizaron los datos de pedigrí para calcular distintos parámetros genéticos poblacionales. Se seleccionaron 385 individuos Polo Argentino para ser genotipados con el microarray Illumina Equine GGP array (70k). Se realizó una caracterización de bloques de homocigosidad (ROH) y de la endogamia a nivel molecular. Se incorporaron datos genotípicos de otras 14 razas equinas para evaluar la estructuración, composición y diferenciación genética. El análisis genealógico reveló que en la última generación más del 70% de los individuos nacieron por transferencia embrionaria. Esto se asoció a una reducción del intervalo generacional y mayor flujo genético entre criadores, pero también al aumento de la endogamia promedio y una contribución genética desigual de ancestros (principalmente Pura Sangre de Carrera - SPC). El coeficiente de endogamia molecular fue mayor que el calculado con datos genealógicos (14% vs. 0,8%, valor-p<0,001) y estuvo caracterizado por la presencia mayoritaria de ROH cortos (<5,5Mb) lo cual demuestra endogamia ancestral. Se identificaron 4 islas ROH ubicadas en los cromosomas 1, 7 y 17, las cuales contenían 25 genes con distintas funciones reportadas. El SPC fue la principal influencia genética de la raza, aunque se observó una leve e incipiente diferenciación genética. Varias regiones genómicas presentaron elevados índices FST entre el Polo Argentino y SPC, conteniendo genes con funciones variadas, las cuales podrían constituir huellas de selección. Finalmente, algunos marcadores asociados a caracteres fenotípicos vinculados a la aptitud deportiva (velocidad y tamaño corporal) demostraron estar bajo selección en el caballo Polo Argentino. El conocimiento de la situación genética de la raza Polo Argentino resulta de especial interés para guiar las decisiones de cría y contribuir con el progreso genético.

Published: September 2023

Purpose: This study investigated the relationship between firm-specific characteristics and environmental disclosure practices of energy firms in sub-Saharan Africa. It examines how profitability, size, and liquidity influence the environmental disclosure index (EDI) of listed energy firms in the region. Research methodology: A quantitative approach was adopted, utilizing secondary data from the annual reports of energy firms listed in Nigeria, South Africa, and Kenya. Regression analysis was employed to assess the impact of firm-specific characteristics on EDI using waste management data based on the Global Reporting Initiative (GRI) 306 guidelines. Results: The findings indicated that Profitability positively affected EDI, indicating greater transparency in reporting environmental initiatives for more profitable firms. Conversely, firm size is negatively correlated with environmental disclosure, suggesting challenges for larger firms in effectively communicating their environmental efforts. However, firm liquidity did not significantly affect EDI. Limitations: One limitation of the study is its focus on energy firms in only three countries, limiting the generalizability of the findings to other sub-Saharan African nations. Contribution: This research contributes to the literature by addressing environmental disclosure practices within sub-Saharan Africa's energy sector, offering stakeholders, policymakers, and regulators insights to promote transparency and sustainability in the industry. Novelty: The novelty of this study lies in its examination of firm-specific characteristics and their influence on environmental disclosure practices in the energy sector of Sub-Saharan Africa. Using waste management data as a proxy for disclosure offers a fresh perspective on the reporting practices of energy firms in the region.

O texto traz, de forma concisa, minha trajetória no Laboratório de Ensino de História e Geografia (LAHIGE), fundado em 1997, por mim e a professora de História, Anna Côgo. Consta, aqui, um resumo das principais atividades desenvolvidas, os percalços, as dificuldades, os sucessos, mas, acima de tudo, a alegria por ter conseguido trilhar esse caminho sempre com muita energia, dedicação e amor, pois, apesar de aposentada, eu continuo ligada ao Projeto. O LAHIGE é um PROJETO INTERDISCIPLINAR E INTERDEPARTAMENTAL, das áreas de conhecimento de HISTÓRIA E GEOGRAFIA. Foi o primeiro laboratório de ensino criado na UESC. Recentemente foi transformado em Núcleo de Ensino. É, portanto, um núcleo permanente, comum aos departamentos do DFCH (Departamento de Filosofia e Ciências Humanas) e do DCAA (Departamento de Ciências Agrárias e Ambientais). Nasceu em julho de 1997, descendente direto do CES (Centro de Estudos Sociais), que fora criado pelas professoras da FESPI, Maria Palma Andrade, Janete Ruiz Macedo e Cleonice Almeida, que atuavam no curso de Estudos Sociais. O Lahige também foi, sempre, um espaço de acolhimento de professores dos dois departamentos que chegavam à Uesc. Muitos deles apresentaram projetos de extensão dentro das linhas do núcleo, a fim de conseguirem a dedicação exclusiva. Para nosso projeto, isso sempre foi um ganho.

A cidade de Ilhéus, localizada na microrregião Ilhéus-Itabuna, está perdendo população desde 2000 (IBGE, 2000), acompanhando o que está acontecendo em seu município desde a década de 1991 (IBGE, 1991). Entretanto, o que podemos notar, por meio da observação direta, confirmada pelas fotografias aéreas, é que esta cidade está crescendo territorialmente. O que está acontecendo para que o município e a cidade de Ilhéus estejam perdendo população? E, contraditoriamente, por que está havendo o crescimento do número de prédios residenciais, de condomínios e de loteamentos fechados? Além disso, em quais direções a cidade de Ilhéus está crescendo? Para responder a estas questões recorremos aos dados populacionais de Ilhéus disponíveis nos Censos Demográficos do IBGE (1980, 1991, 2000, 2010), ao site IBGE Cidades (2021) e ao Atlas de Desenvolvimento Humano no Brasil 2013, mapeamos os condomínios horizontais e as torres de apartamentos construídos após 2000 e entrevistamos cinco corretores de imóveis da localidade. Descrevemos os principais eixos de crescimento de Ilhéus, identificando suas especificidades, discutindo as consequências da periurbanização e da autosegregação socioespacial da população por meio dos condomínios fechados. Detectamos que o município e a cidade de Ilhéus passaram do modelo agrário-exportador para o urbano de comércio e de serviços, sem ter passado pelo modelo urbano-industrial, com consequências gravíssimas para sua população. A cidade, que não teve grande crescimento populacional ao longo da sua história, marca das cidades industriais, passa para a cidade estendida, dispersa em corredores rodoviários e ao longo do litoral atlântico.

Septic arthritis of the knee is a potentially devastating acute joint condition, requiring prompt and accurate management to minimize long-term complications. This article looks at an exceptional case of bilateral septic arthritis of the knee in a 53-year-old patient with diabetes mellitus, who has no history of joint trauma. A thorough analysis of its clinical symptomatology, radiological results and laboratory tests. Direct examination of joint fluid is particularly notable, showing gram-negative bacilli, although microbial cultures remain negative despite repeated attempts. These results were compared with the existing literature on bilateral septic knee arthritis. Clinical implications are explored, including diagnostic challenges in diabetic patients, as well as treatment options and recommendations for future research. In conclusion, this article highlights the importance of effectively recognizing and managing rare cases of bilateral septic knee arthritis, taking into account patient specificities, such as diabetes. It provides useful information to clinicians and encourages further research in this complex area of rheumatology.

Objective: The aim of the study is to evaluate the immunogenicity of the covid-19 vaccine in patients receiving immunomodulators/immunosuppressants or polychemotherapies based on the treatment of the underlying pathology in an internal medicine and onco-hematology department over a period of one year. Materials and methods: Our study was prospective. We included 61 patients. They were all undergoing immunosuppressive therapy or polychemotherapy and had been vaccinated against covid. We performed a series of 9 serological tests before vaccination and 21 days after vaccination, at d+49 after a 1st boost, at 3 months, 6 months, 9 months and 12 months. Only 21% of our patients received a 2nd boost. We divided our population into 4 groups according to the treatments received. Results: The results show a mean age of 50 years +/- 14.85. The sex ratio F/M was +/- 1.10. To better characterize vaccine responders, we compared them with non-responders based on several parameters: age, sex, comorbidities, whether or not the third booster dose had been received, biological work-up, specifically anemia, neutropenia, lymphopenia, hypogammaglobulinemia, and treatments divided into four groups: A lack of vaccine response was not significantly correlated with the use of rituximab at S4, i.e., 3 months (p=0.01), at S6, i.e., 9 months (p=0.034), and at S7, i.e., 12 months (p=0.009). Lack of vaccine response at 12 months was significantly correlated with patients receiving polychemotherapy (p=0.02) or immunosuppressive therapy (p=0.043). Multivariate analysis showed an association between lack of vaccine response at S3 in patients receiving rituximab (p=0.024) and corticosteroid therapy (p=0.02) and in leukopenic patients (p=0.04). At 12 months, i.e., S7, a strong association was found between lack of vaccine response in patients on immunosuppressants (p=0.002) and multidrug therapy (p=0.001).

The introduction of foreign bodies through the anus has become a fairly frequent reason for emergency room visits (Most often voluntary, related to sexual practices). Male gender is the most concerned. The reasons for consultation are rectal discharge, abdominal pain and occlusive syndrome. ASP confirms the diagnosis if the foreign body is radio- opaque, and searches for perforation (pneumoperitoneum): emergency laparotomy. Extraction may be performed under sedation (anal extraction), or by laparotomy in the case of failure or complication.

Aim: To determine the frequency of appendicular peritonitis in the department. To determine the diagnostic and therapeutic aspects. To analyze the results of management. Methodology: This was a retrospective study conducted over a period of 05 years, from 01 January 2017 to 31 December 2021. Results: We collected 136 cases of acute generalised peritonitis, including 75 cases of appendicular peritonitis, i.e. 6.1% of surgical procedures. Males accounted for 73% of cases, with a sex ratio of 2.75 in favour of males. The mean age was 33.73 years, with a standard deviation of 12.22; the extremes ranged from 16 to 65 years. Abdominal pain was the most frequent reason for consultation, accounting for 97% of cases. In most cases, the diagnosis was made on clinical examination. Appendectomy, peritoneal cleansing and drainage were performed in all our patients. Post-operative management was straightforward in 87% of cases. Conclusion: Appendicular peritonitis is one of the most common aetiological entities. It is diagnosed clinically and managed medico-surgically.

Parietal recurrences of colorectal cancer (CRC) are rare, and usually associated with intra-abdominal dissemination. Recurrences of colic ADK of the abdominal wall are isolated in about 10% of cases. Their natural history is poorly known but their occurrence may be late in the course of the disease. Parietal recurrences are painful and debilitating. When isolated, their curative resectability depends on their volume and the possibilities of parietal reconstruction. The aim of this study was to report the observation of a large metastatic mass of the abdominal wall, occurring 37 months after colonic resection for cancer of the right colon.

Posterior reversible encephalopathy syndrome (PRES) is a radio clinical entity associating a reversible central nervous system involvement with a common brain-imaging feature. There is a great variability in the clinical presentation of this syndrome and in the features of its sometimes-atypical imaging appearance. PRES is an unusual neurological complication occurring during pregnancy or in the post-partum period, other than any pre-existing pathology occurred. Vasogenic oedema due to the rupture of the blood-brain barrier seems to be its main cause. We present here the 1st UNUSUAL case of PRES complicating total nephrectomy for destroyed kidney on pyonephrosis in our structure.
