Le deuil et la littérature: une lecture de Clarice Lispector et Judith Butler
Authors: Antonaci Gama Carolina
Published: April 2024

Cet essai porte sur le rapport entre la littérature et le deuil à partir des réflexions de Judith Butler et de l’analyse du récit Mineirinho de Clarice Lispector. D’abord, nous nous penchons sur le deuil de ceux qu’on aime pour y voir notre vulnérabilité par rapport à l’autre qui, disparu, enlève une part de notre propre constitution. Ensuite, nous élargissons cette réflexion pour essayer de comprendre notre attachement à ceux qui nous sont étrangers, éloignés de notre conception de « familier ». Finalement, nous abordons le deuil des ceux qui, ni étrangers ni familiers, séjournent dans les limbes de notre discursivité.
A ponderação resiliente no discurso da personagem “Hamlet”, de William Shakespeare, como elemento disruptor da ação dramática
Authors: Oliveira Jair Pereira
Published: April 2024

O trabalho objetiva discutir de que forma a ação dramática da personagem “Hamlet”, de William Shakespeare, realiza-se no momento em que ela pondera sobre as possibilidades de agir-no-mundo. Essa ponderação se torna o elemento que transforma suas ações diante do mundo. Sendo assim, teremos como base de discussão a crítica feita por Harold Bloom sobre a tragédia. Além disso, discutiremos os princípios de resiliência, como força de intervenção reflexiva diante dos traumas existentes no sujeito “Hamlet”.
Uma bibliografia feminista latino-americana contemporânea comentada
Authors: – PACC/UFRJ Laboratório de Teorias e Práticas Feministas
Published: April 2024

As pautas dos movimentos feministas, nos últimos anos, parecem partir da América Latina. A afirmação é um pouco ousada, ainda mais porque esse ponto de partida não garante que as pautas não sejam depois apropriadas – capturadas e domesticadas – pelos centros; porém, uma olhada nas publicações de teoria feminista de mais visibilidade e o modo como recorrem a fontes e trabalhos de campo latino-americanos, apontam para a força evidente dessas pautas e questões que se apresentam como situadas. O Laboratório de Teorias e Práticas Feministas do PACC-UFRJ se propôs olhar com atenção, então, alguns dos textos contemporâneos produzidos em primeira mão por algumas referências desses feminismos latino-americanos. A escolha dos textos que seriam comentados e a montagem do conjunto se deu de forma coletiva e experimental, seguindo um método que ao mesmo tempo pudesse refletir as escolhas singulares das participantes do Laboratório e apontar para um conjunto de questões que os ultrapassa e que fosse significativo para o debate. A diferença nas dicções e a desistência de uma padronização dos nossos estilos para fazer os comentários respondem a uma vontade de visibilizar ou de deixar entrever as singularidades de nossos modos de escrever, singularidades que são menos estilísticas e mais, enunciações situadas: cada uma de nós carrega percursos diferentes, línguas maternas diferentes, sotaques, formações institucionais, idades, etc.

O rap e o slam: vozes da resistência em contextos pós-coloniais
Authors: Lombas Miguel , Rückert Gustavo Henrique
Published: April 2024

Este artigo analisa a importância do rap e do slam para a articulação de vozes da resistência nos estados colonizados. Para isso, parte de estudos sobre as relações entre estado e poder nas obras de Norberto Bobbio e Pierre Bourdieu, encontrando as especificidades dessas relações em países colonizados no trabalho de teóricos pós-coloniais e decoloniais como Stuart Hall, Gayatri Spivak, Grada Kilomba, Boaventura de Sousa Santos, Aníbal Quijano, Walter Mignolo e Ailton Krenak. As composições analisadas são do rapper angolano MCK e da slammer brasileira Patrícia Meira. Os resultados apontam para uma poética coletiva no rap e no slam, que conecta sujeitos negros, pobres, periféricos, imigrantes, mulheres, LGBTQIA+, em sua experiência de opressão nos diferentes contextos pós-coloniais do mundo.
Uma cartografia poética do slam: Itinerâncias políticas entre corpo e palavra
Authors: Martins de Oliveira Camilla , Bocchetti André
Published: April 2024

O presente texto emerge de uma pesquisa de doutorado em curso e se dedica a acompanhar trajetórias de produção de força das palavras no slam, através das narrativas de quatro poetas. Buscamos dar contribuições às seguintes questões: Como a palavra ganha força de transformação ao ser enunciada? O que as palavras podem mover? O material foi gerado através de um dispositivo específico produzido para esta pesquisa. O slam é um conjunto de operações sobre e a partir da palavra, operações essas que serão acompanhadas nesta cartografia poética, através de dois caminhos: o slam como itinerância entre corpo e palavra e o slam como deriva entre palavra, corpo e política.
Mudas falas mudam as falas na cena poetry slam: a poesia falada brasileira tem cor e gênero
Authors: Pimentel Ary
Published: April 2024

Para investigar o processo de assunção de voz de sujeitos subalternizados, focalizamos na produção poética de mulheres negras no interior da cena poetry slam (batalhas de poesias faladas que se constituem como um campeonato de abrangência local, estadual, nacional e internacional). Os slams de poesia surgem no Brasil como um espaço associado à resistência de sujeitos que trazem diferentes marcas de subalternidade. O recurso à oralidade e à performance voco-corporal colocada em cena nos espaços públicos fomentaram a construção de um lugar de fala para a outridade. Pouco a pouco, a cena vai assumindo uma cara própria e, hoje, podemos dizer que a spoken word no Brasil tem tanto cor como gênero.

A autorrepresentação e a mulher indígena no slam: A poesia de Auritha Tabajara e a ruptura com a representação hegemônica
Authors: Pimentel Ary , Costa Mariana de Oliveira
Published: April 2024

A recente cena do Poetry Slam nos brinda enquanto pesquisadores de literatura a oportunidade de pensar, analisar e discutir temáticas originais e necessárias e nos permite fazer ecoar vozes e produções literárias que há muito são silenciadas nos currículos. Assim, este artigo busca pensar a potência da autorrepresentação através da poesia de Auritha Tabajara e sua relevância na ruptura com a representação hegemônica.
Representações de violência e masculinidade no nordeste brasileiro em “Às suas ordens, sargento”, de Jaime Hipólito Dantas
Authors: Santos Paulo Henrique Raulino dos , Castro Netanias Mateus de Souza
Published: April 2024

Este artigo analisa o conto “Às suas ordens, sargento”, de Jaime Hipólito Dantas, com atenção voltada para as representações de violência e masculinidade através das personagens sargento e Zé Firmino. Para empreender essa análise, foi necessário considerar a construção narrativa como um todo, uma vez que as personagens não atuam sem os demais elementos que fazem parte do seu entorno e de suas composições. Assim, os elementos integrantes da narrativa constroem um universo diegético cujas figurações do masculino necessitam assumir uma performance que conote coragem e disposição para a violência, ainda que ela não se concretize fisicamente. As personagens, portanto, atuam a partir desses lugares sociais, representando masculinidades de hegemonia e subalternidade, ainda que isso se alterne juntamente com a topografia do conto. O duelo veladamente violento constituído pelo sargento e por Zé Firmino se mostra infindo em virtude da própria composição formal do conto que não o encerra, assim como são também aprisionantes as performances de masculinidade na sociedade representada textualmente
O tecido social e o tecer da narrativa: os recursos temático-formais em trânsito no conto “Malagueta, Perus e Bacanaço”, de João Antônio
Authors: Strenske Cleidi , Silva Dias Ellen Mariany
Published: April 2024

Este artigo estuda os procedimentos temático-formais mobilizados pelo escritor João Antônio na produção de sentidos e de efeitos estéticos especificamente no conto “Malagueta, Perus e Bacanaço”, publicado em 1963. A fim de desvendar a poética deste texto, nossa hipótese é a de que a aparente superficialidade dos temas abordados, a saber, o jogo de sinuca e a malandragem, dissimula uma teia complexa que mescla o sujeito urbano, a sociedade, a ficção e a realidade, resultando numa narrativa de resistência.
Using Internet Databases to Advance Health Equity, Population Health, and Workforce Planning
Authors: Nalin Peter , Bright Patrick
Published: April 2024

Physician leaders and policymakers must understand the attributes of their patients’ communities and geographies. Numerous databases provide access to extensive data too numerous to manage casually: U.S. Census data are sortable for information about people and places; HRSA data can be viewed using online data tools and mapping functions; and CDC data is searchable using key words down to the county level. The ESRI Community Analyst tool can synthesize numerous databases that together can elevate the usefulness of census data, community data, and geographic information systems. For physician leaders and their colleagues, these databases and tools can effectively support their understanding of disease burdens and social determinants of health en route to improving the health of patients and populations where they live.

Dimensionamento econômico de pilares com seção retangular utilizando algoritmos genéticos
Authors: Lima Thiago Augustus Remacre Munareto , Lima Marcus Vinicius Carvalho , Brito Marcus Alexandre Noronha de , Oliveira Herbet Alves
Published: April 2024

A busca por soluções estruturais otimizadas tem sido um foco crescente na engenharia civil, com pesquisadores empenhados em desenvolver métodos que garantam estruturas seguras e economicamente eficientes. Nesse contexto, os algoritmos genéticos se destacam como uma ferramenta poderosa para a otimização de seções de pilares de concreto armado. Este estudo visa otimizar seções retangulares de pilares de concreto armado utilizando algoritmos genéticos multiobjetivo a fim de analisar a influência de variáveis como largura, comprimento e área de aço no custo ótimo, para diferentes situações de carregamento. A função objetivo a ser minimizada é o custo total do pilar, composto pelos custos do concreto, aço e formas. As variáveis de projeto consideradas são: largura e altura da seção, área de aço e posição da linha neutra. Foram adotados concreto de 20 MPa e aço de 500 MPa, com esforços normais variando de 250 kN a 600 kN. As restrições baseiam-se na ABNT NBR 6118, como verificação da flexão composta oblíqua, equilíbrio de forças, limites de deformação e taxas de armadura. A solução final da função custo exibe um comportamento linear, com maior influência da largura do pilar até o limite imposto, evoluindo então com contribuições do comprimento e da área de aço quando o pilar é submetido a esforços de maiores magnitudes. As soluções ótimas obtidas fornecem um ponto de partida para o dimensionamento de pilares, evidenciando a importância da otimização de custo na engenharia civil.
Decision-making system for rice production: a case study in the Araranguá River Valley
Authors: Giassi Marcos Antonio Martins , Morales Analúcia Schiaffino , D’aquino Carla de Abreu , Moraes Ricardo Alexandre Reinaldo de
Published: April 2024

This paper addresses the challenges faced by small-scale rice producers in Santa Catarina, including water consumption, salinity issues, and high production costs. To support these producers, a computer-assisted decision-making system is proposed to enhance the production process. The system utilizes a computational model and simulations based on real crop data for validation. The contributions of this study include optimizing water and electricity usage, minimizing losses from excess irrigation and saline water collection. This is achieved through a system that forecasts future flow, determines the optimal timing and amount of irrigation, and evaluates water availability in the river to mitigate salinity risks caused by low rainfall.
An electrochemical sensor based on a modified glassy carbon electrode for detection of epinephrine in the presence of theophylline
Authors: Beitollahi Hadi , Sarbandian Zahra
Published: April 2024

Background and purpose: Neurotransmitters are chemical messengers that enhance and balance signals between cells and target cells in the body. They are vital to the body's ability to function. Epinephrine is one of the most essential catecholamine neurotransmitters with an important biological and pharmacological role in the mammalian central nervous system. Therefore, it is very important to develop sensitive, simple, and fast methods for the determination of this compound. Experimental approach: In the present work, a glassy carbon electrode (GCE) modified with the cerium oxide-zinc oxide (CeO2-ZnO) nanocomposite (CeO2-ZnO/GCE) was developed for the sensitive and quick detection of epinephrine. The CeO2-ZnO nanocom­posite was prepared by hydrothermal method. Electrochemical methods such as voltammetry and chrono­ampero­metry techniques were used to investigate the performance of the developed sensor. Key results: The resulting CeO2-ZnO/GCE showed a remarkable response towards the determination of epinephrine. The electrochemical sensor demonstrated a wide dynamic linear range from 0.1 to 900.0 μM for analysis of epinephrine. The LOD equalled 0.03 μM for epinephrine. In addition, the electrochemical sensor had good feasibility for concurrent detection of epinephrine and theophylline. Furthermore, experimental outputs indicated that the oxidation peaks of epinephrine and theophylline were separated by a 685 mV difference between the two peaks in PBS at a pH of 7.0. Also, an electrochemical sensor has been employed to analyse epinephrine in real samples (urine and epinephrine Injection). Conclusion: The good and acceptable analytical performance of the developed sensor can provide a promising tool for the analysis of epinephrine in real samples.

O DIREITO CONTRA HEGEMÔNICO DAS “BANDEIRAS VERDES” NO CENTRO DE DOMINGOS BALA
Authors: Arruda André Felipe Soares , Sousa Neto Francisco Florentino de
Published: April 2024

As “Bandeiras Verdes” representam a migração dos seguidores do Padre Cícero, fugitivos das agruras do sertão nordestino, em busca de terras desocupadas na Região Amazônica, especialmente no oeste do Maranhão, norte do Tocantins e sul do Pará, para viverem, habitarem e produzirem, formando um campesinato amazônico. Instalam-se em um lugar ermo e de difícil acesso, abrindo com foices e machados seus pequenos roçados e seus caminhos. Após algum tempo começam agregar parentes, aderentes e amigos, formando as comunidades locais denominadas de Centros. No curta metragem “Bandeiras Verdes”, de Murilo Santos (1987), Domingos Bala (Domingos Feitosa da Silva), narra que, na década de 1970, vivia nas terras de um homem muito rico onde era explorado, e por isso resolveu deixá-la em busca de melhores meios de vida nas matas amazônicas, estabelecendo-se com a família e formando os primeiros roçados no local denominado Centro do Bala. A necessidade de contar com a ajuda de outros camponeses, moradores das cercanias, para as atividades agrícolas, principalmente para a derrubada da mata e colheita da lavoura, motivou a atração de novos moradores, para os quais eram destinadas frações do território nas capoeiras, ampliando a comunidade, e, por consequência, a complexidade das relações interpessoais. As relações interpessoais e a organização política dos Centros são reguladas por normas baixadas pelo pioneiro ocupante (“assituante”), e posteriormente pelos líderes da comunidade, apesar das normas impostas pelo poder hegemônico.

Entender as concepções na formação do professor de física pode ser um grande passo para entendermos as dificuldades e fracassos no ensino de ciências exatas. Atribuir esses resultados apenas aos professores e alunos é uma forma limitada de analisar este fenômeno, visto que, indivíduos isolados não possuem capacidade de modificar todo o sistema. Sendo assim, este trabalho busca debater como a ciência e suas relações de poder contextualizam a formação do professor de física. Aqui busca-se relacionar a ciência, tecnologia e a sociedade na tentativa de determinar como a tecnociência afeta e é afetada por nosso sistema capitalista.
ACADEMIC AND SOCIAL SKILLS INTERVENTIONS: A LITERATURE REVIEW
Authors: Wauke Ana Paula Toome , Pizzinato Adolfo
Published: April 2024

This integrative review sought to identify empirical articles on interventions in the educational field whose theoretical basis is Bronfenbrenner's bioecological matrix and the focus was on the development of academic and/or social interaction skills associated with children's learning. The search was carried out using the following descriptors: "psychosocial mathematics", "psychosocial", "psychoeducational", "mathematics", "reading", "writing", "learning", "social" and "social skills", associated with the terms “intervention”, “Bronfenbrenner” and “interaction” in Portuguese, Spanish and English. The review retrieved 59 articles between 1999 and 2020 on the Capes Journal Portal without database restrictions; there were search results in English and Spanish, with no returns in Portuguese. Most returns were in English. 11 articles were analyzed. It should be noted that 6 of them were focused on the period before entering school. It is noteworthy that 3 studies focused on socio-emotional development with an interactional approach. A limiting factor of the study is the low number of articles found, which suggests more research with interventions using Bronfenbrenner's bioecological matrix.

Objetivo: realizar uma análise comparativa entre as características clínicas e epidemiológicas da febre maculosa em populações pediátricas e adultas, relacionando com as variáveis utilizadas no estudo, para entender as diferenças entre as faixas etárias. Métodos: Estudo epidemiológico, observacional, de delineamento transversal com dados do Sistema de Informação de Agravos de Notificação (SINAN-DATASUS) referentes a casos confirmados de febre maculosa no Brasil entre janeiro de 2007 e dezembro de 2022, incluindo indivíduos de todas as faixas etárias. AS variáveis incluídas no estudo foram idade, sexo do paciente, sinais e sintomas clínicos, reservatórios, local de provável infecção, dados clínicos e de diagnóstico. Os microdados foram extraídos diretamente do servidor do DATASUS por meio de script em linguagem R. Para as análises de associação entre as variáveis explicativas e o desfecho, foi utilizado o teste qui-quadrado de Pearson, considerando nível de significância de 0,05. Como medida de associação foi utilizada a odds ratio (OR) ajustada pelo modelo de regressão logística e respectivo intervalo de confiança a 95% (IC95%). Todas as análises foram realizadas no software R versão 4.3.2 (R Core Team, Vienna, Austria).  Resultados: Foram analisados 2709 perfis de febre maculosa, em ambos os grupos, o sexo masculino foi o majoritário, 71,65% em adultos e 62,40% no grupo pediátrico. Febre foi o sintoma mais recorrente, respectivamente, 91% em adultos e 95% na população pediátrica; a hospitalização nas crianças ocorreu com maior frequência: 72,40%, enquanto nos adultos 58,51%, o contato com carrapato foi similar: 85,96 % em adulto e 79,10% no pediátrico, os adultos frequentaram com maior frequência floresta, rio ou cachoeira 80,16 % em comparação 65,11% no grupo pediátrico. Conclusão: O sexo masculino foi mais suscetível, com o ambiente doméstico sendo o local de maior contágio. Na maioria das vezes, crianças são assintomáticas, enquanto na população adulta os sintomas mais comuns incluem dor de cabeça e mialgia. O diagnóstico laboratorial geralmente é limitado, e as taxas de mortalidade são altas.

Internet-delivered cognitive behavioural therapy

Heather D. Hadjistavropoulos, Hugh C. McCall, and Jill A. B. Price, walk us through internet-delivered cognitive behavioral therapy tailored to public safety personnel. Public safety personnel (PSP) are first responders and others who ensure the safety of citizens. Canadian PSP report high rates of mental health disorders and face unique treatment barriers, such as limited time, geographical location, and stigma. Internet-delivered cognitive behavioral therapy (ICBT) is a private and convenient mental health treatment that can be accessed anytime and virtually anywhere. Specifically, clients are provided with treatment strategies in an online course with or without therapist support. Therapist support is typically offered via secure, brief, weekly messages and/or phone calls that are designed to complement, rather than replace, online treatment materials. Hundreds of randomized controlled trials show that ICBT is effective for treating symptoms of anxiety, depression, posttraumatic stress, and more.
Time to strengthen and enforce the north american migratory bird treaty act

Time to strengthen and enforce the north american migratory bird treaty act

The number of migratory bird populations is declining; Keith Hobson, professor and research scientist at Environment and Climate Change Canada and Western University, outlines the importance of updating conventions to protect these vulnerable species. One of the great current challenges of effective wildlife conservation globally involves the protection of migratory organisms that cross international boundaries during their annual cycle. The challenge is obvious when considering the myriad of obstacles involved with international agreements and requirements for on-the-ground compliance, especially when considering different languages, cultures and political systems. Nonetheless, such international cooperation is needed now more than ever as migratory animals have been found to be declining at greater rates than their non-migratory counterparts. That is especially the case for migratory birds. Not surprisingly, apart from regulations involving trade in wildlife or wildlife parts, such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), few success stories exist.

Stem programs: encouraging an early start with engineering design

Nancy Butler Songer, Associate Provost of STEM Education at the University of Utah, highlights the importance of introducing STEM programs to younger students. Fifty years ago, I was one of three girls (of fifty 11 and 12-year-olds) in the after-school Science Club (Figure 1). Equipped with my bicycle and a large butterfly net, my task was to gather and identify fifty different species of insects before school began again in the fall. Little did I know that this activity was a formative experience leading to a career in Science, Technology, Engineering, and Mathematics (STEM) Education. My experience as a twelve-year-old is consistent with a wealth of research indicating that pre-teen interest in STEM fields, including Engineering, is a strong predictor of future careers. Research studies indicate that to increase the number of students pursuing engineering and science as a career goal, we must increase activities with engineering as a fundamental component before students reach their teenage years (Sneider & Ravel, 2021).
Invasive electrical stimulation for stroke treatment

Invasive electrical stimulation for stroke treatment

The CorTec Brain Interchange system is a potential tool to improve motor rehabilitation after stroke (Schuettler, 2023). Here, it is sketched how results from studies of other groups are combined to form CorTec’s vision of a new therapy and how first human data was collected to prove the systems therapy capability. In 1949, the neurophysiologist Donald Hebb postulated “Neurons that fire together, wire together,” which became the theoretical fundament for mechanisms underlying motor rehabilitation, e.g., after stroke. Co‐activation of neurons solidifies and even strengthens their synaptic connections. This “learning” can be utilised in conventional, occupational, or physio‐therapeutic rehabilitation approaches. It has been successfully investigated in animal models for decades that electrical stimulation can facilitate this learning process (Bao, 2020). These studies led to the following practical patient studies on stroke rehabilitation (amongst others):

Purple bacteria and their less known applications

Jungwoo Lee, High-School Student, and Arpita Bose, Associate Professor at Washington University in St. Louis, guide us through purple bacteria and their less-known applications, including wastewater treatment and biofertilization. Purple bacteria, also known as purple photosynthetic bacteria, which belong to the phylum Proteobacteria, can be classified into purple sulfur bacteria (PSB) and purple non-sulfur bacteria (PNSB). In contrast to PSB, PNSB demonstrate the ability to utilize various electron donors and acceptors, which further expands their applications. Their adaptable metabolism, coupled with well-defined genetic manipulation techniques, positions PNSB as ideal models for elucidating the intricacies of metabolic pathways, which hold significant implications for diverse biotechnological applications, including wastewater treatment, and as biofertilizers.

Thermodynamics of hadronization: The rotating lepton model explains key CERN experiments

Constantinos G. Vayenas, Professor at the University of Patras, Academy of Athens, explores the thermodynamics of hadronization, using the Rotating Lepton Model and two key CERN experiments. The observation of neutrino production in the recent pp collision CERN experiments (1) has confirmed that hadrons consist of neutrinos. (2) This is also confirmed by the observed hadron and boson formation during the e+-e- annihilation experiments at CERN (3), where positrons and electrons have been shown to catalyze hadron formation from ambient neutrinos.

Therapeutic potential of the endocannabinoid system to treat chronic pain in inflammatory disease

Pharma researchers Julie Blaising and Philip Smith from F. Hoffmann-La Roche Ltd. discuss the endocannabinoid system as a pathway to treat inflammatory diseases such as Inflammatory Bowel Disease (IBD) and endometriosis. The endocannabinoid system (ECS) is a complex system that comprises the cannabinoid receptors 1 and 2 (CB1 and CB2, respectively), endocannabinoid (EC) ligands, and enzymes involved in the synthesis and degradation of endocannabinoids. (1) It is broadly expressed in the body and modulates physiology and immunity. (2, 3)

The future of AVS, dizziness, and vertigo in emergency departments: Part II. Policy innovations for transformative change

In the second article of this five-part series, Dr Millie Nakatsuka discusses the barriers that contribute to the overuse of neuroimaging associated with the diagnosis of acute vestibular syndrome and proposes systemic reform. In the fast-paced and high-stakes emergency environment, physicians use tacit guidelines and heuristic shortcuts as efficient and accurate methods to support clinical decision-making. These vital intuitive processes are nevertheless vulnerable to cognitive biases that distort healthcare provision, driven by systemic professional, organisational, and public pressures that function as perverse incentives.

Decoding the patterns of spiderweb capitalism

Dr Kimberly Kay Hoang, the Director of Global Studies at the University of Chicago’s Department of Sociology, reflects on ‘spiderweb capitalism’ and her efforts to unravel opaque financial networks worldwide. I am a sociologist interested in deal-making in emerging and frontier markets. I use ethnographic and interview methods to examine highly risky, corrupt markets with no clear rule of law. Introducing the concept of ‘spiderweb capitalism,’ I build on the work of network scholars by exploring the substantive material that flows between two nodes in a network and by uncovering how totally disparate networks are connected. This is especially important in new frontiers where relationships with state officials are crucial to getting insider access to the most lucrative deals and securing profitable exit opportunities.

EURO-CORDEX: A community effort provides the basis for regional climate adaptation in Europe

Climate change is a worldwide threat to humanity and to human activities. Especially in the densely populated continent of Europe, targeted adaptation to the man-made changes in climate is necessary. The facets of climate change differ from region to region, even within Europe, as do human activities within the continent. Therefore, the impacts of climate change are also diverse and are specific to each region. Potential adaptation measures need to consider many different aspects, among which are the projected local climate change, its potential impact, human activities and its costs. A basis for the planning of targeted adaptation measures is the scientifically sound analysis and provision of regional to local climate information. To provide this basis is one of the tasks the EURO-CORDEX community assigned to itself.

The aim of this review is to raise awareness and knowledge among healthcare professionals and policymakers about late adverse effects in survivors of childhood leukemia. With contemporary treatment, over 90% of children with acute lymphoblastic leukemia (ALL) and over 60% with acute myeloid leukemia (AML) are cured. Large cohort studies demonstrate that 20% of ALL and most AML survivors have at least one chronic health condition by 20-25 years after diagnosis. These are life-changing or threatening in some survivors and contribute to increased premature mortality. We describe the frequency, causes, clinical features, and natural history of the most frequent and severe late adverse effects in childhood leukemia survivors, including subsequent malignant neoplasms, metabolic toxicity, gonadotoxicity and impaired fertility, endocrinopathy and growth disturbances, bone toxicity, central and peripheral neurotoxicity, cardiotoxicity, psychosocial late effects, accelerated ageing and late mortality. The wide range of late effects in survivors of haemopoietic stem cell transplant is highlighted. Recent developments informing the approach to long-term survivorship care are discussed, including electronic personalized patient-specific treatment summaries and care plans such as the Survivor Passport (SurPass), surveillance guidelines and models of care. The importance of ongoing vigilance is stressed given the increasing use of novel targeted drugs with limited experience of long-term outcomes.
Conclusion. It is vital to raise awareness of the existence and severity of late effects of childhood leukemia therapy among parents, patients, health professionals, and policymakers. Structured long-term surveillance recommendations are necessary to standardize follow-up care.

Infertility in females is a devastating problem whose solution has posed a lot of challenges due to the difficulty and complexity of identifying the exact cause and etiology among different individuals. This study evaluated copper/zinc ratio, total protein, albumin and reproductive hormones in infertile females in Port Harcourt. This was a case-control study, carried out among residents of Port Harcourt. A total of 130 female subjects within the age of 18 and 49 years were recruited for the study; 65 infertile subjects and 65 apparently healthy fertile control subjects. Approximately 10 mL of blood was collected using standard venipuncture technique from each subject on day 3 and 21 of the menstrual cycle. Samples for copper, zinc, total protein and albumin were analyzed using colorimetric methods, while the reproductive hormones were analyzed using Enzyme-Linked Immunosorbent Assay. Data generated were analyzed using Graph-Pad Prism version 8.0.2 and P≤0.05 was considered statistically significant. This study revealed a significant increase on day 3 and 21 in mean copper 27.68±10.78 and 20.29 ± 16.41 (P<0.001 and P=0.043) levels in infertile women when compared to the mean copper 16.82±4.52 and 15.20 ±5.29 of control group respectively. Copper/zinc ratio was also increased in the infertile group with mean levels of 11.40±1.82 and 3.27 ±0.59 on days 3 and 21 compared to the control group with mean levels of 4.53±0.76 and 1.46 ±0.12 (P=0.010 and P=0.004) respectively.   There was significant decrease on day 3 of Menstrual cycle in Mean ± SD levels of Total Protein 72.62 ±7.84 in infertile group and 77.23 ±4.71 in control group (P< 0.001), and albumin 40.54 ±4.79 in infertile group and 44.82 ±3.64 in control group (P=< 0.001) respectively. There was no significant difference in mean zinc level (P=0.402) on day 3, but mean zinc level 10.74 ±4.58 was significantly decreased on day 21 in infertile females compared to the control 12.91 ±4.73 group (P=0.009). There was also significant increase in mean levels of Luteinizing hormone 8.64 ±4.32 infertile and 7.16 ±2.21 control (P=0.016), prolactin 27.02 ±18.55 infertile and 12.28 ±6.44 control (p<0.001), and testosterone 0.74 ±0.25 infertile and 0.38 ±0.18 control (P<0.001) respectively.   There was a significant decrease in mean levels of estrogen 28.66 ±10.34 infertile and 41.79 ±4.55 control (P<0.001), and progesterone 7.71 ±6.38 infertile and 15.63 ±6.57 control (P<0.001) respectively. However, there was no significant difference in mean levels of follicle stimulating hormone (P=0.519).  The findings in this study indicate that a high copper/zinc ratio is associated with alterations in levels of reproductive hormones. Hence, micronutrient supplementation to maintain optimum levels will be beneficial for infertile females.

In the intricate mosaic of Earth's ecosystems, endemic wildlife emerges as a unique and irreplaceable component, embodying the essence of specific regions. This abstract delves into the profound importance of endemic species for nature as a whole, considering their ecological roles, cultural significance, and the urgent need for conservation measures. Endemic wildlife species, found exclusively in particular geographic areas, contribute significantly to biodiversity. Their specialized adaptations and interactions within ecosystems make them crucial indicators of environmental health and stability. As stewards of intricate niches, these species often play key roles in regulating populations, pollination, and maintaining overall ecosystem balance.
Beyond their ecological functions, endemic wildlife holds profound cultural importance. They become emblematic symbols of regions, shaping local traditions, folklore, and identities. Indigenous communities often form deep connections with these species, integrating them into their spiritual and daily lives. The loss of endemic species, therefore, not only threatens ecological integrity but also erodes cultural diversity and heritage. However, endemic wildlife faces an array of threats in the modern era. Habitat loss due to human activities, climate change altering familiar landscapes, and unsustainable practices place these species at risk of decline and extinction. Urgent action is imperative to address these challenges comprehensively.
Conservation efforts must adopt a multifaceted approach, integrating scientific research, community engagement, and international collaboration. Sustainable land-use practices, habitat restoration, and climate resilience strategies are essential components. Moreover, recognizing and respecting the traditional knowledge of indigenous communities is pivotal for the success of conservation initiatives.
In conclusion, the preservation of endemic wildlife is not merely a biological imperative but a holistic commitment to safeguarding the intricate web of life and the cultural richness woven into our planet. Through unified global efforts, we can ensure that the unique importance of endemic species endures, contributing to the resilience and balance of nature as a whole.

Published: April 2024

Background: Quality Work Life (QWL) is essential for the long-term resilience of healthcare systems and nurses' Well-Being (WB), despite the fact that there hasn't been much research done in Nepal. Purpose: The main aim of this research study is to examine the QWL among nurses and inspect the association b/t QWL with demographic features among nurses. Methods: To study nurses' QWL, a cross-sectional technique was carried out at the selected tertiary-level of Hospital in Basundhara/Dhapasi, Kathmandu; a non-probability enumerative sampling method was adopted based on the QWL survey. The questionnaire has six categories: sociodemographic data, work environment, management relationships, work conditions, job perception, and support services. Validity and reliability were ensured, and informed consent was obtained in writing. The study had 150 registered nurses enrolled in it, and it received ethical approval. Findings: In this study, researchers utilized descriptive and chi-square tests to examine the level of quality of work life (QWL) among nurses and the association of demographic factors with QWL, However, the results demonstrated that the majority (81.3%) of the nurses experienced a moderate level of QWL. Research Limitation/ Practical Implication: Low generalizability, a small sample size, self-reported bias, a cross-sectional design, and limited data collection techniques are some of the study's limitations. Health organizations should invest in training and development, social support, flexible work, and policies that address the work environment, relationships with management, work conditions, job perception, and support services if they want to improve the QWL of nurses in Kathmandu. It is crucial to take activities that increase output and employee happiness. Originality/Value: The originality and value of this study reside in its assessment of the relationship between QWL, quality patient outcome, and nurse well-being, addressing a significant gap in the literature.
