Published: December 2024

This study assessed a male competitive powerlifter over a 6-month period that encompassed his pre-contest preparation and post-contest recovery. We conducted the following monthly assessments: multi-frequency bioelectrical impedance analysis (MF-BIA), B-mode ultrasound evaluation of muscle thickness (MT), body circumferences, handgrip strength, vertical jump height, isometric lower body strength, and questionnaires for perceived mood and sleep. The athlete undertook a 3-month pre-contest preparatory period that included an extreme energy-restricted diet intended to sufficiently reduce body mass. This period also included an 8-week pre-contest training regimen with a 10-day taper intended to promote peak strength increases in the target lifts for competition. During the pre-competition period, the athlete experienced rapid and substantial losses of body mass (10.3%), body fat (6.5%) and lean mass (3.3%), the majority of which was regained in the 2-month post-competition recovery phase. The athlete's isometric knee extension strength rose sharply during the initial month of the pre-competition phase (336.4 Nm), followed by consistent declines (299 to 262.2 to 283 Nm) over the next 3 months, eventually returning close to baseline values 2 months post- competition Jump height remained steady in the 3 months in the pre-contest phase but increased (+1.4 cm) in the 2 months post-competition while handgrip strength increased during the months preceding the competition (47.5 kg to 49 kg) but decreased to 42.3 cm post-competition. Overall, the athlete did not seem to have any marked sleep disturbances. The most notable changes in mood parameters were increased tension, anger, and depression immediately preceding the competition.

Human activities such as population growth, agricultural practices, resource extraction, and urbanization have reduced the functional and structural complexity of ecosystems in small island regions. Landscape changes, including deforestation and habitat fragmentation, have diminished available habitats and increased interactions between primates and humans. In our study, we focused on Kalao and Bonerate Islands in South Sulawesi to evaluate the impact of introduced long-tailed macaques (Macaca fascicularis) on biodiversity and to examine potential human-macaque conflicts. Data were collected through direct field observations to estimate the long-tailed macaque population and habitat use, and through interviews with local residents to understand their perceptions of the species' presence. We estimated the long-tailed macaque population at 1,408 individuals on Bonerate Island and 2,266 individuals on Kalao Island. The long-tailed macaque population density was 0.85 individuals per hectare in secondary forest on Bonerate Island, 0.44 individuals per hectare in old secondary forest on Kalao Island, and 0.18 individuals per hectare in secondary forest on Kalao Island. There is significant potential for human-macaque conflict due to long-tailed macaque crop raiding on both islands, resulting in considerable losses for farmers. Effective management of the introduced long-tailed macaque populations in Kalao and Bonerate requires a comprehensive approach that considers ecological, socio-economic, and conservation aspects. Further data analysis is essential to develop and implement appropriate strategies to address the challenges posed by these introduced populations.

Published: December 2024

The Covid-19 virus is a type of coronavirus that infects humans, causing a pandemic that began in 2019 in China. The vaccine against Covid-19 is capable of protecting the human body against the coronavirus and has reduced the number of morbidity and mortality, although, given the various unreliable information, there is vaccine hesitancy, especially among parents and guardians of children. The objective of this article is to analyze, in scientific literature, the impact of “fake news” on vaccine hesitancy and vaccination coverage of the Covid-19 vaccine in children. This is an integrative review of the literature, which used the Pubmed and Virtual Health Library (VHL) databases, using the keywords “Covid”, “Vaccine Hesitation” and “Child”. After applying inclusion and exclusion criteria, as well as in-depth reading, 12 articles were selected. The results three categories of analysis: Main factors that lead to vaccine hesitancy, Decrease in Vaccination Coverage and Covid-19 Pandemic and; Impact of information and misinformation on the acceptability of the Covid-19 vaccine. There was a need for more studies that aim to understand the main reasons that lead to vaccine hesitancy and the consequent reduction in vaccination coverage, which can lead to outbreaks, epidemics and pandemics. Furthermore, managers and health professionals must use appropriate tools and instruments to disseminate reliable information, according to the target population.

Ovarian goiter: an uncommon ovarian entity
Authors: FEGHOUL Nabyla
Published: December 2024

Struma ovarii, also called ovarian goiter, is a rare congenital entity, a monodermal variant of ovarian teratoma. Most often benign, it represents 1% of all ovarian tumors and preferentially affects women in their fifties. Although the thyroid tissue is reigning, it is exceptionally hyperfunctional. Preoperative recognition of struma ovarii is very difficult to achieve and indifference to other ovarian lesions is very common. Clinical and paraclinical appearance is commonly non-specific and does not provide the diagnosis which is only histopathological, generally unexpected on analysis of the
resected tumour.
Infectious endocarditis complicated by embolic accident such as acute ischemia of the right lower limb. A case report
Authors: LAKEHAL Rédha
Published: December 2024

Infective endocarditis is a severe condition. It is an infection of the endocardium responsible for cardiac failure and cerebral embolisms. The goal of this work is to show a case of mitral endocarditis with ischemia of the lower extremity, secondary to embolic accident. We report the case of an 18 year old young woman presenting in our department for acute ischemia of the right leg with thrombus of the common femoral artery in echodoppler of the legs having to profit from a gesture of fogartisation of the member. Etiological investigation revealed a mitral endocarditis with the presence of mitral vegetation. She was operated in emergency conditions under cardiopulmonary bypass, with mitral reparation after arterial removal of
obstructions from the lower extremity.Postoperative course was simple. Cardiac indication of surgical operation, on the one hand, the moment of this intervention, on the other hand, are difficult decisions. These decisions require a narrow monitoring of the patient, with daily examinations such as CT and the transthoracic or chocardiography. These decisions require also a close collaboration between the doctor, the surgeon and the microbiologist.

Published: December 2024

The Department of Plastic and Aesthetic Surgery, St. Anne‘s University Hospital in Brno, and Faculty of Medicine of Masaryk University, Brno, has a long history of surgical treatment of lymphedema and elephantiasis, which started in 1970s. There were many types of surgeries described and performed at our department – starting with prof. Bařinka‘s radical operation of elephantiasis, then lower limb end-to-side lymphovenous anastomosis pulled through the wall to the great saphenous vein, and genital lymphedema reduction. We call this era “the first period” of surgical lymphedema treatment. “The second period” started in 2016 by using free flaps with lymph nodes or vascularized lymph nodes and using microsurgical techniques of end-to-end, end-to-side and side-to-end lymphovenous anastomoses to the subcutaneous veins of a small calibre, which then drain the lymph into the blood stream. “The third period” started 2 years ago after the visit of prof. Yang from Taiwan – we started to use the method of single stitch end-to-side anastomosis to big subcutaneous veins like the great saphenous vein or the cephalic vein.
¿Está relacionada la Mancha Cálida del Pacífico Sur-Occidental con el Cambio Climático Global?
Authors: Poblete Arnobio Germán , Albeiro Castro María Agustina , Monrroy Paola Belén
Published: December 2024

La comunidad científica mundial ha identificado áreas con un calentamiento anómalo en diversas zonas del planeta; entre las que se encuentra la Hot Blob y/o “Mancha Cálida”. Diversos autores le asignan un rol determinante en el proceso de megasequía en los Andes Áridos.
Esta anomalía de la temperatura superficial del mar en el este de Nueva Zelanda, se ha ido calentando paulatinamente, sin embargo, se advierte que aproximadamente desde mediados de los 2000 se calentó con mayor velocidad. Al parecer la mano del hombre, como resultado de la actividad humana y la quema de combustibles fósiles, ha incidido en ella.
En este artículo, debido a que la relación entre la Hot Blob y el Cambio Climático Global, no es explícita objetivamente, se implementa la temperatura global como índice para valuar asociación entre aquel y la Mancha Cálida.
sujeto y la verdad
Authors: Strajilevich Knoll Florencia
Published: December 2024

El siguiente trabajo parte del análisis de dos obras literarias que vieron su aparición en el siglo XXI: Historia de los abuelos que no tuve, de Ivan Jablonka, y El impostor, de Javier Cercas2, dos novelas que se articulan alrededor de la búsqueda e indagación del pasado a partir de los acontecimientos –y sus efectos– que se desprenden del período de la Segunda Guerra Mundial. Una de las categorías de análisis que se toma es la de voz narrativa cuya construcción, en cada relato, está condicionada por la forma en la que el sujeto se relaciona con la verdad a lo largo del trazado narrativo. Esta relación que se entabla entre sujeto y verdad responde al concepto de “parresia” –segunda categoría de análisis–, término analizado por Michel Foucault en su libro Discurso y verdad; a partir de esta idea se piensa a la verdad no como un objetivo en sí mismo, sino como un camino de búsqueda y transformación permanente a lo largo del cual los individuos intentan comprender “lo que los hombres hacen”.
Borges en la biblioteca de Alonso Quijano
Authors: González Javier Roberto
Published: December 2024

Más allá de sus ensayos sobre el Quijote o que abordan algunos aspectos de él, sus opiniones críticas sobre la novela vertidas en numerosos reportajes y libros de diálogos, sus parciales y fragmentarias recreaciones literarias del gran personaje, y la teoría de la ficción y la lectura implícita en el magnífico ejercicio narrativo de “Pierre Menard, autor del Quijote”, Borges ha dejadouna preciosa clave interpretativa de la gran obra de Cervantes en tres poemas dedicados a Alonso Quijano: los sonetos “Lectores” y “Sueña Alonso Quijano”, y “Ni siquiera soy polvo”. A partir del análisis del primero de los textos poéticos mencionados, y con eventuales apoyaturas en los otros dos, este artículo se propone definir y analizar la peculiar concepción borgeana del Quijote como un gran relato intercalado o de segundo grado, de naturaleza onírica, que narra las aventuras jamás ocurridas y solo imaginadasde Alonso Quijano, y vincular esta hermenéutica –que lleva implícita una virtual reescritura de la obra, en sintonía con el ejemplo de Menard– con las resoluciones estructurales análogas de algunos de los más emblemáticos cuentos de Borges, como “El Sur” y “Ruinas circulares”.

Мұнай кен орындары көп жағдайда олардың құрылымы бойынша біртекті емес қабаттардан түзіледі, бұл олардың жоғары қалдық мұнаймен қанығуын анықтайды. Сондықтан мұндай қабаттардан мұнай өндіруді арттыру қажеттілігі туындайды. Эксперименттік зерттеулер жүргізу үшін белгілі бір фракцияның кварц құмымен толтырылған екі металл құбырдан тұратын модель қолданылды. Бұл әртүрлі өткізгіштік қабаттарын алуға мүмкіндік береді. Бұл модельде біртекті емес қабат мұнай өндіруді арттырудың ұсынылған әдісін зерттеді. Бұл жағдайда біртекті емес қабаттың мұнай өндірісін арттыру үшін полимер ерітіндісін айдауды қолдану ұсынылады. Сарқылған қабатты алу үшін бастапқыда біртекті емес шамамен бірдей дәрежесі бар (Ко=К1/К2) қабатты біртекті емес қабатта әдеттегі сулану жүзеге асырылды

In most cases, oil fields are structurally formed by heterogeneous layers, which determine their high residual oil saturation. Therefore, there is a need to intensify oil production from such reservoirs. To conduct experimental studies, a model consisting of two metal pipes filled with quartz sand of a certain fraction was used. This makes it possible to obtain layers of different permeability. Using this model of a layered heterogeneous formation, the proposed method for intensifying oil production was studied. In this case, the use of polymer solution fringing is proposed to increase the oil recovery of a layered heterogeneous formation. In order to obtain a depleted formation, the usual flooding was initially carried out in a layered heterogeneous formation with approximately the same degree of heterogeneity (Co = K1/K2)

Нефтяные месторождения в большинстве случаев по своей структуре образованы неоднородными слоями, которые и определяют их высокую остаточную нефтенасыщенность. Поэтому возникает необходимость в интенсификации добычи нефти из таких пластов. Для проведения экспериментальных исследований была использована модель, состоящая из двух металлических труб, заполненных кварцевым песком определенной фракции. Это позволяет получать пласты разной проницаемости. На данной модели слоисто-неоднородного пласта изучали предлагаемый способ интенсификации добычи нефти. В данном случае для увеличения нефтеотдачи слоисто-неоднородного пласта предлагается применение оторочки раствора полимера. С целью получения истощенного пласта первоначально осуществили обычное заводнение в слоисто-неоднородном пласте с примерно одинаковой степенью неоднородности (Ко=К1/К2)

Authors: Jovan John D. , Foggle John
Published: December 2024

Introduction: At the onset of coronavirus disease 2019 (COVID-19), many healthcare institutions activated the Hospital Incident Command System (HICS) to manage their pandemic response. The current literature includes numerous case reports describing individual institutional responses. This paper serves to synthesize the various lessons learned published in the current literature.
Methods: This systematic review consists of articles identified by searching three online databases: PubMed, Scopus, and Google Scholar. The authors used the search themes “Hospital Incident Command System” and “COVID” to identify articles to screen for inclusion. Finally, 12 articles published between 2020 and July 2022 met the inclusion criteria and were selected for review.
Results: Eight articles (66.7 percent) discussed how the HICS improved communication within their organization. Eight articles (66.7 percent) described unique modifications to the HICS structure that enabled the organization to adapt to the challenges of the pandemic. The flexibility of the HICS allowed each individual organization to modify its structure to best respond to COVID-19. These modifications improved internal communication between hospital leadership, staff, and the community. Implementation of the HICS helped organizations to streamline communication by preventing information overload.
Conclusion: In conclusion, the HICS provided healthcare institutions with a flexible structure to effectively tailor their emergency response to the unique challenges within their institution and the local community during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic had dramatic impacts throughout the United States (US). In Cameron County, Texas, along the Texas–Mexico border, the impacts of the virus were felt more severely than in most places in the US. Residents of the county, which has high rates of poverty, many multigenerational households, high levels of underlying conditions, and an uninsured population of almost 30 percent, were not only poised to be affected by the virus but also by the response policies put in place to contain it.
This study seeks to add to the literature by examining the lived experiences of low-income individuals in Cameron County, Texas, as it relates to the COVID-19 response and their experiences with the response. To do this, we asked: How did the COVID-19 response affect low-income residents in Cameron County, Texas?

ETHICS, SUBJECTIVITY AND THE SEARCH FOR JUSTICE
Authors: Alves de Oliveira Rose , Vinicius Lopes Marcus
Published: December 2024

This article explores the relationship between the subject and the norm, addressing how ethics acts in the construction of individual subjectivity and in conflicts with social and legal norms, especially in contemporary issues such as the objectification of women on social media and civil disobedience. With an approach based on naturalist ethics and postmodern morality, and supported by the theories of Fraser (2007) and Fabriz (2003), the research investigates the effects of norms on mental health and fundamental rights, highlighting how the search for social recognition clashes with practices and structures that perpetuate oppression and patterns of behavior. The analysis criticizes objectification and the imposition of aesthetic and gender standards, defending an inclusive ethics that respects diversity and individual autonomy, thus promoting a more just and egalitarian society.

Published: December 2024

A presente pesquisa buscou compreender os aspectos motivacionais dos atletas do programa de extensão em atletismo da Universidade do Estado de Mato Grosso, no município de Cáceres/MT. Trata-se de uma pesquisa quanti-qualitativa em que participaram atletas jovens adultos (n=07) que frequentam o referido projeto. Os instrumentos utilizados para coleta de dados foram questionário sociodemográfico e questionário motivacional (EMI-2) que possuem questões estruturadas com dimensões relacionadas às características dos atletas, contexto familiar, ambiente da prática esportiva e motivação para o esporte. Foi possível identificar que os aspectos motivacionais que levam os atletas do projeto universitário em atletismo a praticar essa modalidade está relacionado com uma maior relevância nas dimensões “Agilidade”, “Manter-se saudável”, “Competição”, “Revitalização”, “Força/resistência”, “Desafio”, “Saúde”, “Prazer/diversão”, “Reconhecimento social”, “Gestão do estresse”, sendo crucial para a prática de exercício físico. Os achados sugerem que os atletas universitários priorizaram fatores associados à motivação intrínseca (algo interior), e isso pode favorecer para a permanência mais efetiva e duradoura na prática esportiva, notadamente em ambientes como o analisado.

O objetivo do estudo foi analisar o estado de humor dos Árbitros de Futsal durante cada dia de competição. Participaram 25 árbitros (média de 39,2 ± 8,4 anos) convocados para competições oficiais. Utilizou-se de questionários de caracterização dos participantes e a Escala de Humor de Brunel. Para análise dos dados utilizou-se estatística descritiva, Teste “t” de Student e Mann Whitney (p≤0,05). Resultados indicaram que apesar da dimensão vigor ter os maiores valores médios, apenas 24% da amostra manteve-se dentro do intervalo desejados. A dimensão fadiga obteve as maiores variações durante a semana e apresenta pico em fases importantes das competições, tal qual a dimensão raiva. Árbitros com mais idade permaneciam mais tempo na zona alvo na dimensão raiva e árbitros com mais tempo de experiência de atuação, na dimensão vigor. Reitera-se a preocupação com a preparação e atuação dos árbitros nas competições em busca de um melhor desempenho na atuação.
