Renal replacement therapy is the indicated treatment for individuals with chronic kidney disease (CKD) to survive. However, not all sick people have access to the same treatment. This study compares renal care in two developing countries with different health systems. Specifically, it explores hemodialysis treatment from the perspective of low‐income individuals. A qualitative, comparative study was performed in Brazil and Mexico. Using purposive sampling, the research was based on open‐ended interviews with nineteen participants with kidney failure undergoing hemodialysis treatment in (...) public hospitals and ten relatives. According to our results, Brazilian participants perceived hemodialysis care as satisfactory because of health personnel courtesy as well as free access to dialysis treatment, prescription drugs, hospitalization and transportation. However, they reported deficiencies in the care they were receiving due to shortages of specialists, prescription drugs, laboratory tests and transportation. Mexican participants, in contrast, highlighted the catastrophic costs of medical care because they had no free access to renal therapy, nor adequate financial resources. Our findings suggest that low‐income Brazilian CKD sufferers experience renal care differently, as they are more satisfied and face less obstacles with hemodialysis compared with those of Mexico. More studies on the topic are needed. (shrink)

Esperamos que este dossiê possibilite aos leitores uma reflexão sobre a problemática geral do governo das diferenças e dos corpos ingovernáveis, particularmente, que encontrem nesse conjunto de artigos algumas respostas para o enfrentamento da face obscura do biopoder no presente. Nossa expectativa também é a de que os eventuais impactos que esses corpos e suas alianças com a arte produzem na formação humana e em sua educação filosófica, tragam tanto à filosofia da educação quanto ao ensino de filosofia alguma oxigenação, (...) quem sabe, entusiasmando-nos a extrapolar os pensamentos, práticas de pesquisa e de ensino, que também são nossas.

An international group of environmental philosophers and educators propose ways universities can produce and promote ecological literacy and environmental ethics.

Proteoglycan 4 (PRG4), first identified in synovial fluid, is an extracellular matrix structural protein in the joint implicated in reducing shear at the cartilage surface as well as controlling adhesion‐dependent synovial growth and regulating bulk protein deposition onto the cartilage. However, recent evidence suggests that it can bind to and effect downstream signaling of a number of cell surface receptors implicated in regulating the inflammatory response. Therefore, we pose the hypothesis: Does PRG4 regulate the inflammatory response and maintain tissue homeostasis? (...) Based on these novel findings implicating PRG4 as an inflammatory signaling molecule, we will present and discuss several hypotheses regarding potential mechanisms by which PRG4 may be able to regulate inflammation. If future studies can demonstrate that PRG4 is a potent inflammatory mediator, this will change current paradigms in the musculoskeletal and ophthalmological fields regarding the how the inflammatory microenvironment is regulated in these tissues and potentially others.

We first show that a theorem by Cartan that generalizes the Frobenius integrability theorem allows us (given certain conditions) to obtain noncurvature solutions for the differential Bianchi conditions and for higher-degree similar relations. We then prove that there is no algorithmic procedure to determine, for a reasonable restricted algebra of functions on spacetime, whether a given connection form satisfies the preceding conditions. A parallel result gives a version of Gödel's first incompleteness theorem within an (axiomatized) theory of gauge fields.

Physical activity and sedentary behaviour have been linked to the mental health of children and adolescents, yet the timing of behaviours may play a role in this relationship and clarifying this could inform interventions. We explored cross-sectional associations of PA and SED in varying time segments throughout the school day with the mental health of school-aged children and adolescents from rural Northeastern Ontario, Canada. A total of 161 students wore accelerometers for 8 days and completed a self-report survey. Mental health (...) was measured using the Strengths and Difficulties Questionnaire. Accelerometer-measured SED, light PA, and moderate and vigorous PA were estimated in the time-segments before school, school time, after school, and evenings. Associations were tested with multilevel linear regressions while adjusting for confounding factors. Students spent 72.6 min in MVPA, 209.0 min in LPA, and 621.0 min in SED per day. Daily SED was associated with less conduct problems. Evening LPA was inversely associated with hyperactivity, while SED was associated with hyperactivity and with peer problems before school, and during school. No associations were observed for MVPA, emotional symptoms, or prosocial behaviour. In conclusion, displacing SED with LPA in some specific periods of the day may benefit the mental health of students; taking this into account could strengthen interventions. (shrink)

O ponto de partida do presente ensaio é o entendimento de que a arte constitui um dos motivos catalisadores, se não mesmo um dos temas maiores da reflexão de Maurice Merleau-Ponty. Na interpretação do autor, o filósofo da percepção, aquele que, de todos os pensadores contemporâneos, conferiu ao corpo po um estatuto que a reflexão do século XX ainda não lhe concedera, chegou à arte por necessidade intrínseca do seu próprio caminho especulativo, vindo a reflexão sobre a expressão artística a (...) dar um contributo essencial para a constituição do seu próprio pensamento, contributo esse que se vai adensando, desde a Fenomenologia da Percepção até O Visível e o Invisível e O Olho e o Espírito, a ponto de poder dizer-se que na arte, particularmente na arte moderna, encontrou Merleau-Ponty uma filosofia à l'oeuvre, apesar da ausência do conceito, a que é, de facto, alheia a expressão artística.

This book examines the social and political character of love. Like everything else, love must be seen at multiple levels: human society (in its relation to nature and in relation to the materiality of human life itself); specific forms of class society such as capitalism.

Consciousness is an active area of both philosophical debates and scientific research. Consciousness Quest, rather than covering the broad spectrum of consciousness spread over multiple scientific disciplines, refocuses the quest for consciousness on a specific area where Eastern contemplative traditions, mostly in Hindu and Buddhist theories of mind, meet Western empirical research. This book is an introduction to current scientific thinking and research on consciousness and at the same time acquaints readers with the spectrum of classical and modern philosophical notions (...) on consciousness.

The majority of antimicrobials that are produced are administered to animals, particularly food animals. While the overall impact of antimicrobial use in animals on antimicrobial resistance in humans and the environment is unclear, it undeniably has a role. Yet, some degree of antimicrobial use in animals is necessary for animal health and welfare purposes. Balancing the benefits and risks of antimicrobial use in animals is challenging because of the complexity of the problem and limitations in available data. However, a range (...) of measures can be implemented to reduce, refine and optimize antimicrobial use in animals, with a goal of minimizing the impact on human and environmental health while maintaining necessary therapeutic use in animals. A pandemic instrument can provide the necessary foundation for the whole-of-society and whole-of government One Health approach that is required to strengthen surveillance, communication, collaboration, and action.

Our goal was to explore self‐care practices among men who have sex with men in the context of Mpox in Brazil. This study used qualitative research methods, including interviews and thematic analysis, to collect and analyze data from male participants across the Brazilian territory. The narratives unveil men's perspectives on self‐care, risk reduction, and health beliefs during the Mpox pandemic. Our findings highlight a multifaceted approach to self‐care among men, encompassing hygiene, physical contact management, mask usage, skin lesion vigilance, and (...) adherence to official guidelines. Men's attitudes toward sexual behaviors emphasize the importance of reducing sexual partners, practicing safe sex, and combating misinformation through accurate information dissemination. The development of these behaviors and self‐care practices can be facilitated by nurses guided by Dorothea Orem's Self‐Care Theory, supported by patient‐centered care, with strategies to address and confront the stigma associated with the disease and provide emotional support. Thus, the study underscores the pivotal role of self‐care in mitigating infection risks, especially in the context of emerging infectious diseases. It acknowledges the impact of socio‐cultural factors and healthcare policies on men's preventive measures. However, it also recognizes limitations, such as potential bias due to stigma concerns and a nonrepresentative sample. Ultimately, the research advocates for tailored education, promotion of gender equity, and healthcare empowerment to effectively manage health risks in such contexts. (shrink)

Nanoparticles of cobalt ferrite prepared by the co-precipitation method with crystallite size varying from 4.7 to 41 nm have been characterized by positron annihilation lifetime spectroscopy. Three lifetime components are fitted to the lifetime data. The shortest lifetime component is attributed to the delocalized positron lifetime shortened by defect trapping. The intermediate lifetime is assigned to the positron annihilation in diffuse vacancy clusters or microvoids at the grain boundaries and at the grain-boundary triple points. The longest component corresponds to the (...) pick-off annihilation of ortho-positronium formed at the larger voids. The variations in these lifetimes and their relative intensities with annealing temperature and crystallite size have been studied in detail. (shrink)

The guiding inspiration of this book is the attraction and distance that mark the relation between anthropology and philosophy. This theme is explored through encounters between individual anthropologists and particular regions of philosophy. Several of the most basic concepts of the discipline—including notions of ethics, politics, temporality, self and other, and the nature of human life—are products of a dialogue, both implicit and explicit, between anthropology and philosophy. These philosophical undercurrents in anthropology also speak to the question of what it (...) is to experience our being in a world marked by radical difference and otherness. In The Ground Between, twelve leading anthropologists offer intimate reflections on the influence of particular philosophers on their way of seeing the world, and on what ethnography has taught them about philosophy. Ethnographies of the mundane and the everyday raise fundamental issues that the contributors grapple with in both their lives and their thinking. With directness and honesty, they relate particular philosophers to matters such as how to respond to the suffering of the other, how concepts arise in the give and take of everyday life, and how to be attuned to the world through the senses. Their essays challenge the idea that philosophy is solely the province of professional philosophers, and suggest that certain modalities of being in the world might be construed as ways of doing philosophy.
