RISING STARS: Endocrine regulation of metabolic homeostasis via the intestine and gut microbiome
Authors: Meyer Rachel K , Duca Frank A
Published: May 2023

The gastrointestinal system is now considered the largest endocrine organ, highlighting the importance of gut-derived peptides and metabolites in metabolic homeostasis. Gut peptides are secreted from intestinal enteroendocrine cells in response to nutrients, microbial metabolites, and neural and hormonal factors, and they regulate systemic metabolism via multiple mechanisms. While extensive research is focused on the neuroendocrine effects of gut peptides, evidence suggests that several of these hormones act as endocrine signaling molecules with direct effects on the target organ, especially in a therapeutic setting. Additionally, the gut microbiota metabolizes ingested nutrients and fiber to produce compounds that impact host metabolism indirectly, through gut peptide secretion, and directly, acting as endocrine factors. This review will provide an overview of the role of endogenous gut peptides in metabolic homeostasis and disease, as well as the potential endocrine impact of microbial metabolites on host metabolic tissue function.

The problem of scientific investigations in the selection of fixators for osteosynthesis in treating ailments with fractures and deformities of the facial skeleton bones, which will require reconstructive surgery, is considered. Literature data on the use of various types of materials for osteosynthesis are given. It was established that the development of new biologically active composite materials for the production of bone plates for osteosynthesis, which would meet the basic requirements of bone surgery: biocompatibility, strength, flexibility, ability to biodegrade, stimulation of tissue regeneration and prolonged therapeutic action, is an urgent direction of modern science and practical medicine. To solve this problem, the use of fixation structures for osteosynthesis based on biodegraded epoxy polyurethane (EPU) composite material with bioactive action (EPU-HAP-LEV) is proposed. Biological activity is ensured by the presence of hydroxyapatite and levamisole fillers in the EPU composite. Representative results of physical-mechanical, physical-chemical, and medical-biological studies, which preceded clinical trials of the composite material EPU–HAP–LEV in the form of osseous plates for osteosynthesis, are given. According to the obtained results, the EPU–HAP–LEV composite material is non-toxic, biocompatible and bioactive, capable of biodegradation and prolonged release of levamisole, has the necessary strength characteristics (flexural strength - 27.1 MPa, tensile strength - 24 MPa, relative elongation at break 5.3 MPa), which made it possible to manufacture fixators for osteosynthesis in the maxillofacial area and allowed to recommend them for clinical use. In the clinic, 76 patients with facial skull fractures were treated with polymer plates with screws, which are made of the EPU-HAP-LEV composition. An example of the clinical use of bone plates for osteosynthesis made of EPU-LEV-HAP is presented and their compliance with the medical purpose, effectiveness in the surgical treatment of maxillofacial fractures in areas that do not bear a significant masticatory load, as well as in biomechanically stable fractures is established.

The article is devoted to the chemical synthesis of a zeolite/polyaniline (Zt/PAn) composite and a comparative (relative to polyaniline, PAn) study of some of its physicochemical properties, in particular, structural, thermal, and adsorptive (regarding Cr(VI)) characteristics. The results of the studies of spectral, thermal and electrical properties of the initial natural filler mineral (zeolite), synthesized individual samples of polyaniline and Zt/PAn confirmed that the latter are a composite. It was determined that the structure of the polymer in the synthesized samples of both individual polyaniline and the zeolite/polyaniline composite is mostly amorphous and corresponds to the emeraldine salt of sulfuric acid, which is deposited in the form of a thin film on the surface of polycrystalline particles of a finely dispersed mineral. The study of the thermal properties of the samples of individual polyaniline and composite showed that the polymer content in the composite is approximately 50%. The results of studying the adsorption capacity of PAn and Zt/PAn samples proved their high efficiency (98–99%) in removing of Cr(VI) from aqueous solutions. The study of the Cr(VI) adsorption kinetics at its content in the initial solutions of 200–500 mg/L showed that the process is two-stage, and the adsorption capacity of both samples of individual polyaniline and the zeolite/polyaniline composite depends on the concentration of the initial solutions. An increasing of the initial concentration of Cr(VI) in the solutions leads to a certain decreasing in absorption degree and values of adsorption at the first stage of the process by both samples of the PAn and the Zt/PAn. The course of the second stage of sorption, which obviously has the nature of absorption, is longer, but it is during this stage that almost 98–99% removal of Cr(VI) from the investigated solutions is achieved. In particular, it was established that with a Cr(VI) content of 500 mg/L in the investigated solution, the adsorption capacity of zeolite/polyaniline composite samples is 49 mg on 1 g of adsorbent. At the same time, additional studies showed that the adsorption capacity of polyaniline in the sample of the Zt/PAn composite (i. e., without taking into account the mass of finely dispersed mineral filler) reaches 93 mg/g for the identical content of Cr(VI) in the adsorption solution.

Policy & Change: An Analysis of Veteran Perpetrated Mass Shootings & Social Work's Call to Action
Authors: Collins Christopher
Published: May 2023

Public mass shootings are relatively rare occurrences in the United States. As such, focusing on individual-level factors to develop a prevention framework is ill-advised. However, starting with veterans, as an overrepresented group of offenders, may be an important step to determining and developing policies that work to prevent mass shootings. The Veteran’s Administration (VA) is the largest employer of social workers in the United States and employs more than 15,000 master’s level social work professionals. Policy and training changes made to the VA system have the potential to begin reducing incidents of public mass shootings. The purpose of this study was to determine whether veteran-status or the phenomenon of leakage influences the number of casualties in public mass shootings. Further, a renewed call-to-action is issued for social workers engaged with veterans, military personnel, and their families. A negative binomial regression analysis was utilized to examine 168 public mass shootings events in the United States from 1966 until 2019. While veteran status was not associated with increased casualty this does not underscore the importance of policy changes that limit access to firearms for high-risk people. Further, because leakage was statistically significant in explaining casualty rates in mass shootings additional training related to duty to warn may be necessary for social workers engaged in therapeutic relationships with veterans, military personnel, and their families. The results of the negative binomial regression offer insights into what effective policy interventions may look like to reduce mass shootings.
Arabian Sea Humpback Whale (Megaptera novaeangliae) Singing Activity off Netrani Island, India

Published: May 2023

Arabian Sea humpback whales (Megaptera novaeangliae), listed as “Endangered” on the International Union for Conservation of Nature’s Red List, remain resident throughout the year in the waters of the Arabian Sea and constitute a genetically isolated population. In the eastern Arabian Sea, information on humpback whales off the Indian coast has largely been limited to stranding records, local ecological knowledge, and opportunistic visual sighting data. These data, along with information from a long-term study off Oman, suggest that humpback whales migrate across the Arabian Sea into Indian territorial waters from October to March. To study the presence of Arabian Sea humpback whales in Indian waters more comprehensively, passive acoustic monitoring (PAM) was initiated along the west coast of India in 2019. Male humpback whales produce complex songs with a stereotyped structure; these songs are shared within a population, and song patterns are known to evolve progressively over time. In this article, a structural analysis of humpback whale song recorded over four days off the coast of Netrani Island, Karnataka, India, in December 2019 is presented. Time-frequency features of 2,641 individual call units were analysed. Call units had a fundamental frequency bandwidth ranging from 149.98 to 541.65 Hz, with a duration ranging from 1.19 to 5.5 s. The call units were used to identify phrases and themes required to construct the structure of the song, which can potentially help identify the population to which singing individuals belong. This study indicates the need for a long-term PAM program across the Arabian Sea to compare whale songs across the region. Simultaneous recordings over multiple seasons will best assess population connectivity, seasonal occurrence, and movement patterns within and between populations across the Arabian Sea and the Indian Ocean.
Site Fidelity of Coastal Bottlenose Dolphins (Tursiops truncatus) off Southeast Florida, USA
Authors: Boehning Graysen D. , Brunnick Barbara J. , Harzen Stefan , Hirons Amy C.
Published: May 2023

The coastal bottlenose dolphin is well studied throughout its natural range, though most research focuses on wide, well-protected habitats such as bays and estuaries rather than on narrow coastal sand banks. This study identifies a residential group of coastal bottlenose dolphins utilizing the northwestern Atlantic waters off the coast of Palm Beach County, Florida. From 2014 to 2020, 313 boat surveys were conducted, and 585 individual dolphins were identified using photo-identification. Using seasonal and annual resighting ratios, 24 dolphins were considered full-time residents, 66 dolphins were considered part-time residents, and 478 dolphins were transient. The presence of individuals with high site fidelity indicates that the region is used as a permanent habitat for some individuals, while the presence of transient animals may indicate a possible bridge between populations living to the north and south of the region.

The cooperation of the Council of the Baltic Sea States, which was established on 5–6 March 1992, to a large extent is based on the activity of various international, local, governmental and non-governmental organisations that function in the Member States to the CBSS. Annual Ministerial Sessions and Summits serve the purpose of maintaining relations of the states in the region and help to create a foundation for cooperation. As it was proved in practice, the sessions are also a forum for discussion for the EU Member States and a place where common goals and approaches to economic and political challenges are identified. The course of the sessions proves that the implementation of the Copenhagen Declaration of 1992, which was at the foundation of CBSS, has furthered understanding and trust between the states in the region. The documents passed at the end of each Ministerial Session provide political guidance for broadening cooperation between the Member States of the Council.

Belarus plays a crucial role in Russian Federation’s foreign policy. It results from Belarus’ geopolitical, militant and transit significance for Russia. Forming the commonwealth between these two countries was the most advanced unification process in the last decade of the 20th century among the post-soviet states. However the change in Russia’s attitude towards the bilateral relations could be noticed when Vladimir Putin was elected to the fist presidency in 2000. In reaction to the numerous strict disagreements regarding the integration plan proposed by Russia, authorities in Moscow decided to put a pressure on the most vulnerable to attack part of backward Belarusian economy – low oil and gas prices – which allowed it to develop despite the internal difficulties. The rise in oil and gas prices at the turn of 2006–2007 led to a serious recession in bilateral relations between Russia and Belarus. Moscow’s decision to increase the prices had a huge negative impact on Belarusian economy. Further exacerbation of Russian tight pricing policy towards Belarus was established in 2010. What are the prospects for the future? Russia is definitely not going to abandon the plans for Belarus. Therefore Alexander Lukashenko is going to face a choice between Russian support (leading to greater dependence on Moscow) and resumption of the difficult dialogue with the West (resulting in changing the attitude towards the opposition).

Published: May 2023

The article describes in a concise manner the origin and development of anthropology of religion in the global scale and its beginnings in Kyrgyzstan. Three periods of Kyrgyzstan’s history are represented in the research: the pre-revolution era, the Soviet and the contemporary times. An emphasis was put on the unique challenges that each of these periods poses to religious studies. The article analyses one of the major aspects of anthropology of religion – searching for cultural relics of the ancient cults in the contemporary religious trends. The author presents the research methodology that was used while studying religious cults in Kyrgyzstan in the framework of anthropology of religion. The relevance of this paper lies in the fact that interdisciplinary anthropological research on the variety of religious life in different historical periods helps to better understand the history of the peoples of the Kyrgyzstan and their cooperation, as well as to identify the moral values and ideological framework for the contemporary society of Kyrgyzstan.

The political and economic transformation in Estonia after 1991 have contributed to a development of the press market. Unfortunately, in the mid 1990s this market slumped as a result of various barriers: capital, infrastructural, staffing-related, and resulting from poor adaptation to the newly introduced market economy. Another major factor was a lack of adequately educated journalists and financial problems. However, despite a decrease in newspaper readership, the transformation did not result in mass bankruptcies of publishing houses and closing down titles. Since the mid 1990s, newspapers have to contend with the electronic media. The rapid development of the Internet, the newly established radio and TV channels and a growing number of satellite receivers are all strong adversaries of the traditional press. German and Scandinavian capital was introduced to the Estonian press market. Moreover, there was a shift of perspective regarding the role of the journalists in the society
Recentralization, intergovernmental conflicts and territorial inequality: perspective of local governments in Peru

Published: May 2023

Abstract Intergovernmental conflicts, in Latin America’s centralism and the recentralization in Peru, have been more acute over the last 30 years, producing sociopolitical, economic, and cultural problems at subnational levels. Based on the design of the grounded theory of Glasser and Strauss, this sociopolitical phenomenon is analyzed from the perspective of local governments in the Puno region to account for the emerging categories and subcategories of analysis regarding the dynamics of intergovernmental relations (IGR) in the local public policy process. The main argument is that, as a result of centralism, recentralization, and intergovernmental conflicts, territorial inequality reproduces and reinforces at the local level. These are expressed in a dichotomy between the deficit territorial dynamics (backward areas) and entrepreneurial territorial dynamics (growth areas).

Published: May 2023

Resumen Desde los noventa, la idea de gobernanza ha permeado los debates acerca de la transformación del Estado a escala regional, sin embargo, las dificultades de su operacionalización han limitado nuestro conocimiento. Este artículo busca contribuir con esta brecha, examinando la dimensión interjurisdiccional de la gobernanza regional. Aplicando la perspectiva de análisis de redes, se estudia la formación de las redes intermunicipales que se configuran a partir de diferentes mecanismos de colaboración. Con base en el marco de acción colectiva institucional, el artículo analiza la prevalencia de estructuras de relacionamiento asociadas a diferentes tipos de capital social (bonding - capital social vínculo ‒ y bridging - capital social puente ‒) en tres redes intermunicipales de la región de Los Lagos, en Chile. Por medio de la aplicación de modelos de grafos aleatorios exponenciales (ERGM), se obtiene evidencia para sustentar la consistente prevalencia de bonding en las tres redes estudiadas y su coexistencia con estructuras descentralizadas en las redes de mayor complejidad regional.
The multidimensional construct of precarious work, the future of work, and workers’ health
Authors: Fernandes Rita de Cássia Pereira
Published: May 2023

This essay aims to discuss the flexibilization of work, which has been accentuated during the COVID-19 pandemic, leading to an expansion of precarious work. Additionally, the essay seeks to explore theoretical models and methodological challenges for the study of precarious work, its dimensions, and its effects on workers’ health. The health and economic crisis has heightened the social vulnerability of workers, introduced by the global flexibilization and the Brazilian Labor Reform. The setbacks materialize in precarious work, a multidimensional construct that encompasses the characteristics of this flexibilization in its three dimensions: (1) unstable work relationships resulting from insecure hiring, temporary contracts, involuntary part-time work, and outsourcing; (2) inadequate and unstable income; and (3) insufficient rights and protection, with reduced collective representation of workers, resulting in low power to react to degrading working conditions, lack of social security, and setbacks in regulatory support for labor safety. Repercussions of precarious work on health − work accidents, musculoskeletal and mental disorders - are evidenced in epidemiological studies, highlighting the theoretical and methodological limitations that still exist. The conclusion is that if the current bases of social protection and work insertion for workers are maintained, the future will see an expansion of precarious work. Thus, highlighting the causal relationships between precarious work and health is a contemporary challenge of the research and public policy agenda that is imposed upon society, with a focus on workers’ health services.

Published: May 2023

ABSTRACT BACKGROUND Colorectal cancer (CRC) is a worldwide health problem whose control depends on public policy establishment and effective prevention and screening programs. In Brazil, there are few studies related to adherence to screening methods. AIMS: The aim of this study was to evaluate the association between demographic and socioeconomic to adherence to CRC screening with fecal immunochemical test (FIT) among average-risk individuals for CRC. METHODS: In this prospective cross-sectional study, conducted between March 2015 and April 2016, 1,254 asymptomatic individuals aged 50–75 years, participating in a hospital screening campaign in Brazil, were invited to participate in the study. RESULTS: The adherence rate to FIT was 55.6% (697/1,254). In the multivariable logistic regression analysis, patients aged 60–75 years (odds ratio (OR)=1.30; 95% confidence interval (CI): 1.02–1.66; p=0.03), religious belief (OR=2.04; 95% CI: 1.34–3.11; p<0.01), previous fecal occult blood test (OR=2.07; 95% CI: 1.55–2.76; p<0.01), and full/part-time working status (OR=0.66; 95% CI: 0.49–0.89; p<0.01) were independently associated with adherence to CRC screening. CONCLUSION: The results of the present study highlight the importance of considering the labor aspects when implementing screening programs, suggesting that campaigns conducted in the workplace and repeated over the years may be more effective.

ABSTRACT BACKGROUND New therapies have revolutionized the treatment of Crohn’s disease (CD), but in some countries, the surgery rate has not changed, the frequency of emergency surgery is underestimated, and surgical risk is poorly studied. AIMS: The aim of this study was to identify risk factors and clinical indications for primary surgery in CD patients at the tertiary hospital. METHODS: This was a retrospective cohort of a prospectively collected database of 107 patients with CD from 2015 to 2021. The main outcomes were the incidence of surgery treatment, types of procedures performed, surgical recurrence, surgery free time, and risk factors for surgery. RESULTS: Surgical intervention was performed in 54.2% of the patients, and most of the procedures were emergency surgeries (68.9%). The elective procedures (31.1%) were performed over 11 years after diagnosis. The main indications for surgery were ileal stricture (34.5%) and anorectal fistulas (20.7%). The most frequent procedure was enterectomy (24.1%). Recurrence surgery was most common in emergency procedures (OR 2.1; 95%CI 1.6–6.6). Montreal phenotype L1 stricture behavior (RR 1.3; 95%CI 1.0–1.8, p=0.04) and perianal disease (RR 1.43; 95%CI 1.2–1.7) increased the risk of emergency surgeries. The multiple linear regression showed age at diagnosis as a risk factor for surgery (p=0.004). The study of surgery free time showed no difference in the Kaplan-Meier curve for Montreal classification (p=0.73). CONCLUSIONS: The risk factors for operative intervention were strictures in ileal and jejunal diseases, age at diagnosis, perianal disease, and emergency indications.

Resumo A insulinoterapia empregada no tratamento do Diabetes Mellitus (DM) carece de ferramentas educativas que auxiliem a prática de autocuidado. Dessa forma, objetivou-se elaborar e validar uma ferramenta educativa destinada a promover a compreensão da relação entre variação glicêmica e insulinoterapia em adultos com DM1 e DM2. Trata-se de um estudo metodológico desenvolvido em três etapas: i) elaboração da ferramenta educativa; ii) validação de conteúdo e aparência por comitê de juízes; iii) pré-teste com o público-alvo. Participaram da segunda etapa dez juízes e da terceira etapa 12 adultos com DM 1 ou 2, em uso de insulina. Para avaliar a adequação do material educativo pelo comitê de juízes foi utilizado o Índice de Validade de Conteúdo (IVC). Para validação pelo público-alvo foram calculados os percentuais de concordância por itens. Como resultado, desenvolveu-se a ferramenta educativa Meu Diário de Tratamento (MDT), que obteve IVC médio de 99,6% e percentual de concordância de 99%. Conclui-se, portanto, que o conteúdo e a aparência da ferramenta MDT foram validados e adequados culturalmente para a população de adultos com DM tipo 1 e 2.

Resumo As incertezas sobre a COVID-19 requerem avaliação das respostas nacionais, visando identificar sucessos e fracassos no seu controle. Este artigo analisou a resposta portuguesa, particularmente a contribuição dos seus sistemas de saúde e de vigilância no enfrentamento à pandemia. Foi realizada uma revisão integrativa da literatura, sendo incluídas consultas a observatórios, documentos e sites institucionais. A resposta portuguesa foi ágil e revelou uma coordenação técnica e política unificada. Contou com estrutura de vigilância e uso de telemedicina. A reabertura foi amparada na alta testagem, baixa positividade e regras rígidas. Contudo, o relaxamento das medidas a partir de novembro/2020 resultou em aumento de casos com colapso do sistema de saúde. A resposta a esta situação envolveu estratégia de vigilância consistente, com instrumentos de monitoramento inovadores, que, aliados à alta adesão da população à vacinação, levaram à superação daquele momento e mantiveram baixos índices de hospitalizações e óbitos em novas ondas. Nesse sentido, o caso português evidenciou os riscos de recrudescimento com a flexibilização, a exaustão da população em relação a medidas restritivas e novas variantes, mas também a importância da articulação entre a coordenação técnica, a esfera política e o comitê científico.

Published: May 2023

Resumo No contexto do trabalho hospitalar durante a COVID-19, é preciso reconhecer que as atividades de apoio exercidas por maqueiros, agentes de limpeza e auxiliares administrativos são imprescindíveis para o processo de trabalho. Este artigo analisou resultados de uma etapa exploratória de uma pesquisa ampla com esses trabalhadores dentro de uma unidade hospitalar referência para COVID-19 no estado da Bahia. Foram selecionadas três entrevistas semiestruturadas produzidas a partir da perspectiva do “fazer falar” sobre o trabalho, utilizando pressupostos da etnometodologia e da ergonomia. A análise incidiu sobre as atividades de trabalho de um maqueiro, um agente de limpeza e uma auxiliar administrativa, problematizadas a partir da díade essencialidade-invisibilidade. O estudo demonstrou que esses trabalhadores são invisibilizados pela desvalorização social de suas atividades e nível de escolaridade e resistem apesar das circunstâncias e do sobretrabalho; e evidenciou a essencialidade desses serviços pela interdependência entre o trabalho de apoio e o trabalho assistencial e suas contribuições para a segurança do paciente e da equipe. Conclui-se que é necessário criar estratégias para que esses trabalhadores sejam valorizados social, financeira e institucionalmente.

Resumo O objetivo foi analisar a distribuição espacial da má oclusão (MO) em adolescentes, estimar a prevalência e avaliar os fatores associados. Estudo com dados de 5.558 adolescentes entre 15 e 19 anos de idade do inquérito - SB São Paulo 2015. O desfecho foi a MO. As variáveis independentes foram os aspectos sociodemográficos, acesso aos serviços odontológicos, cárie e perdas dentárias. Foram incluídos 162 municípios do estado de São Paulo e aplicadas técnicas de estatística espacial. Foram realizados modelos de regressão logística hierarquizada. A prevalência de MO foi de 29,3%. Houve um padrão de espalhamento entre os tipos de MO e correlação espacial positiva (p<0,05). Adolescentes não brancos (OR=1,32, IC95%: 1,24-1,42), com menor tempo de estudo (OR=1,30, IC95%: 1,22-1,42) e com dentes extraídos por cárie (OR=1,40, IC95%: 1,03-1,88) tiveram mais chances de apresentarem MO. O acesso dos adolescentes à consulta odontológica não contribuiu para reduzir a chance de apresentar a MO, independentemente de a consulta ao dentista ter ocorrido há menos (OR=2,02, IC95%: 1,65-2,47) ou há mais de um ano (OR=1,63, IC95%: 1,31-2,03). Assim, a ocorrência de MO é desigualmente distribuída no estado de São Paulo, e associada a condições sociodemográficas de acesso à consulta e perda dentária por cárie.
Political action analysis of the Brazilian Health Care Reform Movement in the COVID-19 pandemic: 2020- 2021
Authors: Santos Jamilli Silva , Teixeira Carmen Fontes
Published: May 2023

Abstract The aim of this study is to analyze the political action of the Brazilian Health Care Reform Movement (MRSB, Movimento da Reforma Sanitária Brasileira), particularly Cebes and Abrasco, during the COVID-19 pandemic. The data were obtained through the documental review of publications from the abovementioned entities, which describe their positions on government actions implemented between January 2020 and June 2021. The results show that the performance of these entities included several actions, most of them reactive and critical of the Federal Government’s role in the pandemic. Moreover, they led the creation of “Frente pela Vida”, an organization that brought together several scientific entities and civil society organizations, whose highlight was the preparation and dissemination of the “Frente pela Vida Plan”, a document that contains a comprehensive analysis of the pandemic and its social determinants, as well as a set of proposals to face the pandemic and its effects on the population’s living and health conditions. It is concluded that the performance of the MRSB entities reveals alignment with the original project of the Brazilian Health Care Reform (RSB, Reforma Sanitária Brasileira), emphasizing the relationship between health and democracy, the defense of the universal right to health and the expansion and strengthening of the Brazilian Unified Health System - SUS (Sistema Único de Saúde).
Suicídio de mulheres no Brasil: necessária discussão sob a perspectiva de gênero
Authors: Dantas Eder Samuel Oliveira , Meira Karina Cardoso , Bredemeier Juliana , Amorim Karla Patrícia Cardoso
Published: May 2023

Resumo O suicídio de mulheres constitui um problema de saúde pública e há escassez de literatura científica que discorra sobre a temática. Neste ensaio teórico, buscou-se discutir o suicídio de mulheres no Brasil, sob a perspectiva de gênero. Para isso, adotou-se a concepção que gênero extrapola o conceito de sexo, tendo em vista que as diferenças entre as pessoas são produzidas pela cultura e arranjos pelos quais uma sociedade transforma a sexualidade biológica em realizações da vida humana. Este texto foi organizado de modo a sinalizar alguns modelos explicativos do suicídio de mulheres, discutindo as desigualdades de gênero e abordando a questão da interseccionalidade a partir de uma visão protetiva. Ademais, acredita-se que o tema abordado é de extrema complexidade, tendo em vista que ainda resistem estigmas e preconceitos referente a este.

Objective: to map the knowledge produced about the repercussions imposed by the COVID-19 pandemic on Nursing training. Method: this is a Scoping Review, guided by the recommendations set forth in the Joanna Briggs Institute Reviewer’s Manual and carried out in 15 electronic databases and theses and dissertations repositories. The protocol was registered at the Open Science Framework. The data were analyzed and synthesized into two pre-established analysis categories: positive and negative repercussions; and descriptive statistics. Results: 33 publications identified, the most cited positive aspects were the development of new teaching strategies adapted to the virtual environment and the training of future professionals in clinical practice in the context of a health crisis. The negative repercussions are related to psychological issues such as increase in the cases of anxiety, stress and loneliness among the students. Conclusion: the diverse evidence suggests that remote teaching was a timely emergency way out for the continuity of academic training; however, this educational modality presented positive and negative aspects that need to be rethought for a better systematization of teaching-learning in other contexts that resemble the COVID-19 pandemic.

Abstract The Yarinacocha lake is an emblematic ecosystem of the Peruvian Amazon, representing the main point of fish landing and a tourist attraction in the city of Pucallpa. The wide fauna diversity in this area has made it the target of various studies, although for fish species most of them were focused on commercial species. In this work, we carried out the first ichthyofauna species inventory of the Yarinacocha lake, sampling throughout the entire lake during the rainy and dry seasons and considering also all previously recorded species deposited in the Ichthyological Collection of the MUSM with the same locality. A total of 164 fish species were recorded, representing 10 orders (plus Eupercaria), 34 families and 116 genera. Characiformes was the order with more species (68 spp., 41.5%) followed by Siluriformes (59 spp., 36%), Cichliformes (17 spp., 10.5%), and Gymnotiformes (8 spp., 4.9%). The most highly represented families, including almost 55.5% of the total diversity obtained, were Characidae (23 spp., 14%), followed by Cichlidae (17 spp., 10.4%), Loricariidae (14 spp., 8.5%), Pimelodidae (13 spp., 7.9%), Doradidae (13 spp., 7.4%) and Anostomidae (12 spp., 7.3%). From the total fish species recorded in this study, only 22 are considered protected species following the IUCN criteria and 109 species have commercial importance, including 90 ornamental species (54.8%). Our results contribute to the knowledge of the ichthyofauna of the Yarinacocha lake and can be used as a starting point for its conservation and sustainable management over time.
Impact of the cash position on the performance of Brazilian companies during periods of economic recession
Authors: Bortoluzzo Adriana , Bortoluzzo Mauricio , Ferreira Mario M. S.
Published: May 2023

Abstract Purpose: This study aims to analyze if, during periods of economic recession, the cash position impacts the performance of Brazilian companies. In addition, it seeks to identify if there are differences in the intensity of such relationships for the different sectors in which companies operate. Originality/value: The appropriate management of a company’s cash position is key for the maintenance of its financial health in the long term. This subject is particularly relevant for emerging countries, such as Brazil, considering the track record of frequent economic recessions. Such economic recessions lead to the deterioration of the companies’ operating results and shortage of credit facilities, negatively affecting the companies’ liquidity. In the last decade, studies have been discussing the relevance of the companies’ cash position to improve their performance in periods of financial constraint. Design/methodology/approach: To develop this study, a sample composed of 200 Brazilian companies listed on B3 was used, grouping information from the period between 2013 and 2016, organized in a balanced dynamic panel. Findings: The results obtained through regressions indicate that there is a positive and statistically significant relationship between cash position and the performance of the companies, measured by the return on assets (ROA) – but not by the market to book ratio –, and it was also identified that the sector in which the company operates has a moderating factor on the intensity of such a relationship.

RESUMO O objetivo deste artigo é analisar o estado atual dos processos relacionados à Gestão do Conhecimento no Sistema de Bibliotecas Integradas do Instituto Federal de Santa Catarina, visando propor um conjunto de práticas que contribua para a sistematização da Gestão do Conhecimento nessas bibliotecas. A pesquisa trata de um estudo de caso de abordagem qualitativa e caráter descritivo. Para coleta de dados, conduziram-se sete entrevistas semiestruturadas aplicadas a bibliotecários atuantes no referido sistema de bibliotecas, além da pesquisa documental, utilizada para triangulação dos resultados. A análise de conteúdo foi empregada para o tratamento dos dados. Os principais resultados indicaram que o Fórum de Bibliotecas é uma importante estratégia do sistema de bibliotecas. O acervo físico é elementar, porém existem esforços para ofertar recursos digitais. Os diversos perfis de usuários exigem estratégias para atender a diferentes públicos. A infraestrutura tecnológica é apropriada, contudo não são empregadas tecnologias emergentes. Os espaços físicos são amplamente utilizados e são heterogêneos entre as bibliotecas do sistema. Há potencial para organizar um Grupo de Trabalho que proporcione a evolução de discussões sobre Gestão do Conhecimento. O Framework GC@BU reconhece as bibliotecas como Sistemas Adaptativos Complexos e pode amparar a sistematização da Gestão do Conhecimento, considerando a necessidade de adaptação.

Abstract This work aimed to characterize the allspice leaves essential oil (EO) and evaluate its antimicrobial activity against specific food-borne pathogenic microorganisms as well as its in vitro antioxidant activity. The antioxidant activity of different concentrations (0, 500 and 1000 mg/kg) of allspice EO was also evaluated in mechanically deboned poultry meat (MDPM) during storage of up to 10 days at 2 °C. Allspice EO presented as major compounds eugenol (55.52%), myrcene (22.53%) and chavicol (5.12%), and was effective against Gram-negative (P. aeruginosa) and Gram-positive (Staphylococcus aureus) bacteria, having greater (p < 0.05) antimicrobial activity than its main component eugenol. In the in vitro antioxidant assays, the allspice EO had higher radical scavenging activity (90% versus 65%) than eugenol, presenting lower IC50 values (2.71 versus 9.49 µg/mL), but the antioxidant activity by the 2-thiobarbituric acid reactive substances (TBARS) did not differ (p > 0.05) from the synthetic antioxidant butyl-hydroxytoluene (BHT). Incorporating allspice EO in MDPM suppressed lipid oxidation during 8 days of cold storage, regardless of the amount used, exhibiting lower (p < 0.05) TBARS values during all storage periods than MDPM without EO. Allspice leaves EO had the high antioxidant potential to be used in MDPM and could also contribute an antimicrobial effect to the product in which the MDPM is used.

ABSTRACT Among the efficient strategies to manage plant parasitic nematodes, the use of resistant cultivars stands out for being frequently the easiest and least expensive approach that can be adopted by farmers. However, for the common bean, in Brazil, few sources of resistance have been identified so far. This study aimed to assess the reaction of 81 common bean genotypes to the most abundant and harmful plant parasitic nematode species in Brazilian crop fields. Genotypes resistant to all tested nematodes were observed: 7 to Heterodera glycines, 2 to Pratylenchus brachyurus, 15 to Meloidogyne incognita and 8 to M. javanica.
