Interstitial Lung Disease Mortality Disparities Along the US-Mexico Border, 1999-2020.

BACKGROUND: Optimal diagnosis and management of interstitial lung diseases (ILDs) needs access to specialized centers, frequent monitoring, and complex therapeutic options. In underprivileged areas, these necessities can often lead to barriers in delivering care. RESEARCH QUESTION: What are the ILD mortality disparities in the regions along the US-Mexico (US-MX) border? STUDY DESIGN AND METHODS: We obtained ILD mortality information through death certificate queries from the Centers for Disease Control and Prevention repository. Death data were adjusted for age and stratified by US-MX border regions and nonborder regions in the United States. Log-linear regression models were used to analyze mortality trends in the period from 1999 to 2020 followed by calculation of annual percentage changes (APCs). Age-adjusted mortality rates (AAMRs) were compared across cumulative and subdemographic populations. RESULTS: ILD-related mortality among border regions (AAMR, 5.31) was higher than nonborder regions (AAMR, 4.86). Mortality within border regions remained unchanged from 1999 to 2020 (APC, 0.3; P = .269). Nonborder regions experienced a significant rise in mortality rates (APC, 2.6; P = .017) from 1999 to 2005 and remained unchanged from 2005 to 2020. Mortality was higher within both men (AAMR, 6.57) and women (AAMR, 4.36) populations among border regions compared with their nonborder counterparts (AAMR, 6.27 and 3.87, respectively). Hispanic populations among the border regions experienced higher mortality rates (AAMR, 6.15) than Hispanic populations within nonborder regions (AAMR, 5.44). Non-Hispanic populations encountered similar mortality rates between the two regions. Mortality rates among Hispanic (APC, 0.0; P = .938) and non-Hispanic (APC, 0.2; P = .531) populations in the border regions remained unchanged from 1999 to 2020. INTERPRETATION: These results revealed ILD-related mortality disparities among the US-MX border regions, emphasizing the importance of public health measures to increase access to equitable medical care and implement targeted interventions among these vulnerable populations.

Ethical regulation of biomedical research in Brazil: a quality improvement initiative.

BACKGROUND: Q-CEP (Qualificação dos Comitês de Ética em Pesquisa que compõem o Sistema CEP/Conep) is a nationwide project resulting from a partnership between the Brazilian National Research Ethics Commission (Conep), the Ministry of Health and Hospital Moinhos de Vento (HMV). It was developed to consolidate policy for ethical review of research with human beings in all members of the CEP/Conep System, Brazil's national system of institutional review boards. The aim of this study was therefore to report on the experience and results of the Q-CEP project. METHODS: An observational, retrospective study includes data from the Q-CEP, obtained from visits to all the institutional research ethics committees (RECs) in the country. The actions implemented by Q-CEP were part of a two-step process: (i) training visits to each REC; (ii) development of distance learning modules on strategic topics pertaining to research ethics evaluation. The data presented herein cover step one (training visits), defined by Q-CEP as the diagnostic stage of the project. For a country with social and economics inequalities such as Brazil, this is a particularly important stage; an accurate picture of reality is needed to inform planning of quality improvement strategies. RESULTS: In 2019-2021, Q-CEP visited 832 RECs and trained 11,197 people. This sample covered almost all active RECs in the country; only 4 (0.5%) were not evaluated. Of the 94 items evaluated, 62% did not reach the target of at least 80% compliance and around 1/4 (26%) were below 50% compliance. The diagnostic stage of the process revealed inadequacies on the part of the RECs in their ethical reviews. The analysis of informed consent forms showed compliance in only 131 RECs (15.74%). The description of pending issues made by RECs in their reports was compliant in 19.33% (n = 161). Administrative and operational aspects were also considered inadequate by more than half of the RECs. CONCLUSIONS: Overall, Brazilian RECs showed poor compliance in several aspects of their operation, both in ethics evaluation and in other processes, which justifies additional training. The Q-CEP project is part of a quality improvement policy promoted by the Brazilian Ministry of Health. The data obtained in the diagnostic step of the project have contributed to the qualification and consolidation of one of the world's largest research ethics evaluation systems.

United States-Mexico Border Disparities in Alcoholic Liver Disease Mortality: A Cross-Sectional Analysis 1999-2020.

BACKGROUND: US-Mexico (US-MX) border regions are impacted by socioeconomic disadvantages. Alcohol use disorder remains widely prevalent in US-MX border regions, which may increase the risk of alcoholic liver disease (ALD). GOALS: We aimed to characterize ALD mortality trends in border regions compared to non-border regions from 1999 to 2020 in the United States (US). METHODS: We performed a cross-sectional analysis using the CDC repository. We queried death certificates to find ALD-related deaths from 1999 to 2020, which included demographic information such as gender, race/ethnicity, and area of residence. We estimated age-adjusted mortality rates (AAMR) per 100,000 population and compared the AAMRs across border and non-border regions. We also explored yearly mortality shifts using log-linear regression models and calculated the average annual percentage change (AAPC) using the Monte Carlo permutation test. RESULTS: In all, 11,779 ALD-related deaths were identified in border regions (AAMR 7.29) compared with 361,523 in non-border regions (AAMR 5.03). Border male (AAMR 11.21) and female (AAMR 3.77) populations were higher compared with non-border male (AAMR 7.42) and female (2.85) populations, respectively. Border non-Hispanic populations (AAMR 7.53) had higher mortality compared with non-border non-Hispanic populations (4.79), while both populations experienced increasing mortality shifts (AAPC +1.7, P<0.001 and +3.1, P<0.001, respectively). Border metropolitan (AAMR 7.35) and non-metropolitan (AAMR 6.76) regions had higher mortality rates compared with non-border metropolitan (AAMR 4.96) and non-metropolitan (AAMR 5.44) regions. CONCLUSIONS: Mortality related to ALD was higher in border regions compared with non-border regions. Border regions face significant health disparities when comparing ALD-related mortality.

Genetic Structure and Diversity in Wild and Cultivated Populations of the Mangrove Oyster Crassostrea gasar from Southern Brazil.

The mangrove oyster (Crassostrea gasar) is Brazil's second most cultured species and presents a high potential for aquaculture. However, artificial selection in a highly fecund species and significant variance in reproductive success can result in the loss of genetic diversity and increases the inbreeding rate, especially in cultivated populations. In this study, we investigated the genetic structure and diversity of C. gasar in wild and cultivated populations using 14 microsatellites. Spatial genetic comparisons revealed the existence of two main genetic groups of C. gasar, one comprising the population in cultivation and the other formed by wild populations along the southern and southeastern Brazilian coasts. Although no common genetic structure exists among wild populations, it is possible to observe a distribution gradient based on discriminant analysis of principal components consistent with their geographic distribution. However, it is insufficient to differentiate them genetically. Despite artificial reproduction, the genetic diversity values of the cultivated population remained relatively high and did not show a reduction. Therefore, monitoring the cultivated population and establishing reference values for genetic diversity will allow the adoption of strategies both for the viability of the cultivated population and the management of wild populations.

Use of Inverse Method to Determine Thermophysical Properties of Minimally Processed Carrots during Chilling under Natural Convection.

The aim of this study was to determine the thermophysical properties and process parameters of cylindrical carrot pieces during their chilling. For this, the temperature of the central point of the product, initially at 19.9 °C, was recorded during chilling under natural convection, with the refrigerator air temperature maintained at 3.5 °C. A solver was created for the two-dimensional analytical solution of the heat conduction equation in cylindrical coordinates. This solver and the experimental data set were coupled to the LS Optimizer (V. 7.2) optimization software to simultaneously determine not only the values of thermal diffusivity (α) and heat transfer coefficient (hH), but also the uncertainties of these values. These values were consistent with those reported in the literature for carrots; in this study, the precision of these values and the confidence level of the results (95.4%) were also presented. Furthermore, the Biot numbers were greater than 0.1 and less than 40, indicating that the mathematical model presented in this study can be used to simultaneously estimate α and hH. A simulation of the chilling kinetics using the values obtained for α and hH showed good agreement with the experimental results, with a root mean square error RMSE = 9.651 × 10-3 and a chi-square χ2 = 4.378 × 10-3.

Optimization of Extraction Method of Anthocyanins from Red Cabbage.

Among the vegetables that stand out for their high concentration of anthocyanins, red cabbage appears as one of the most-used sources of these pigments in food production and it is considered a suitable raw material for the extraction of natural dye. Therefore, the objective was to carry out the production of natural extracts from red cabbage, under different conditions, varying the solvent, type of pre-treatment, pH range, and processing temperature during the concentration of the extracts. The anthocyanins were extracted from red cabbage using the following solvents: distilled water, 25% ethyl alcohol, and 70% ethyl alcohol. The raw material was divided into two groups, the first was subjected to a drying pre-treatment at 70 °C for 1 h and for the second group, the extraction was performed with the raw material in natura. Two pH ranges of 4.0 and 6.0 and extraction temperatures of 25 °C and 75 °C were used in the extracts, resulting in 24 formulations. The extracts obtained were analyzed for colorimetric parameters and anthocyanins. The results of anthocyanins show that the methodology that uses 25% alcohol, pH 4.0, and processing temperature of 25 °C produces a reddish extract and better results in the extraction, presenting average values of 191.37 mg/100 g of anthocyanins, being 74% higher compared to the highest values obtained in the other extracts where the same raw material was used and the solvents differed.

Influence of Dehydration Temperature on Obtaining Chia and Okra Powder Mucilage.

Gum and mucilage from seeds and fruits are objects of study because they have characteristics of high viscosity at low concentrations and gelling properties, which are useful characteristics for modifying the texture and stabilizing products in the food industry. Chia and okra have high concentrations of polysaccharide gums in their composition, which makes them an interesting target for use in the composition of foods that require the use of texture enhancers and stabilizers. The present study investigated the influence of dehydration temperature on the characteristics of chia and okra powder mucilage obtained at different temperatures. The mucilages were extracted using an aqueous process and dehydrated in an air circulation oven at 50, 60, and 70 °C until hydroscopic equilibrium. Then, the powdered chia mucilage (CM) and okra mucilage (OM) were analyzed for chemical and physicochemical characteristics, bioactive compounds, antioxidant activity, and physical properties. It was found that powdered mucilage had low water content and water activity, with CM standing out in terms of ash, pectin, and starch content and OM, along with higher averages of proteins, sugars, total phenolic compounds, anthocyanins, flavonoids, and antioxidant activity. As for the physical parameters, CM stood out in relation to greater solubility and lower hygroscopicity, whereas OM presented higher wettability rates. Both powdered mucilages were classified as having good fluidity and cohesiveness from low to intermediate. In relation to the dehydration temperature, the best mucilage properties were verified at 70 °C. The study revealed that mucilages have good functional properties offering great potential as raw material for industry.

The Temperature Influence on Drying Kinetics and Physico-Chemical Properties of Pomegranate Peels and Seeds.

Pomegranate is a fruit desirable for its nutritional and medicinal properties which has a great industrial potential that is yet under-explored. Notable for its integral use, the peels are used in medicinal infusions and the seeds consumed without restrictions. In this sense, the objective of this work is to determine the drying kinetics of pomegranate peels and seeds in a hot air circulation oven, at temperatures of 50, 60, and 70 °C, adjust mathematical models to experimental data, determine the effective diffusivities and thermodynamic properties of the process and the physicochemical characteristics of peels and seeds of fresh pomegranates and in their flours. Twelve models were used to adjust the drying kinetics, obtaining better results with the Diffusion Approximation model, Verma, and modified Henderson and Pabis. The effective diffusivities were well represented by an Arrhenius equation, with activation energies of 31.39 kJ/mol for seeds and 10.60 kJ/mol for peels. In the drying process, the seeds showed higher values of enthalpy, entropy, and Gibbs free energy concerning peels. Pomegranate peel and seed flours have proximal composition and distinct physicochemical characteristics, with high fiber, carbohydrate, and energy content. In addition, peel flours stand out for their mineral content, and seed flours do for their lipid and protein content.

Abstract This article examines the continuities, ruptures and temporalities in the production of bioidentities in the context of the HIV-AIDS epidemic. Based on a multi-site study at the confluence of biomedical areas and sub-areas that rose in popularity in the 1980s and 1990s, it questions the common research agendas under the influence of terms and categorizations popularized during the sexual panic of AIDS caused by the increase in contagion rates and death. The methodological design is characterized as mixed methods and primarily involved documental research and thematic review on academic production in the areas and disciplines included under the aegis of the biosciences, in order to search for and select primary studies on homosexuality and HIV/AIDS, through global production. The conclusions attest that the management of AIDS in its treatable chronic condition produced elective and correspondence affinities between epidemiological and social categories (MSM/PWA, GMLA) with defined notions of gender and sexuality.

Mathematical Models to Describe the Foam Mat Drying Process of Cumbeba Pulp (Tacinga inamoena) and Product Quality.

The present study investigated the mathematical modeling foam-mat drying kinetics of cumbeba pulp and the effect of drying conditions on the color and contents of ascorbic acid, flavonoids, and phenolic compounds of the powder pulps obtained. Foam-mat drying was carried out in a forced air circulation oven at temperatures of 50, 60, and 70 °C, testing foam-mat thicknesses of 0.5, 1.0, and 1.5 cm. The increase in the water removal rate is a result of the increase in air temperature and the decrease in the thickness of the foam layer. Among the empirical and semi-empirical mathematical models, the Midilli model was the one that best represented the drying curves in all conditions evaluated. Effective water diffusivity ranged from 1.037 × 10-9 to 6.103 × 10-9 m2 s-1, with activation energy of 25.212, 33.397, and 36.609 kJ mol-1 for foam thicknesses of 0.5, 1.0, and 1.5 cm, respectively. Cumbeba powders showed light orangish colors and, as the drying temperature increased from 50 to 70 °C, for all thicknesses, the lightness value (L*) decreased and the values of redness (+a*) and yellowness (+b*) increased. Foam-mat drying at higher temperatures (60 and 70 °C) improved the retention of ascorbic acid and flavonoids, but reduced the content of phenolic compounds, while the increase in thickness, especially for flavonoids and phenolic compounds, caused reduction in their contents. The foam-mat drying method allowed obtaining a good-quality cumbeba pulp powder.

Suboccipital extracranial and intracranial abscess of a neonate: an exceedingly rare occurrence.

Intracranial abscess is a life-threatening disease that is uncommon in paediatric populations. Although there have been few reports in the literature, some aetiologies, such as mastoiditis and sinusitis, have been proposed. The pathophysiology is not completely known, and there are no data regarding the long-term follow-up of these patients. Herein, we present a case of a newborn affected with a mass in the suboccipital region due to an extracranial and intracranial abscess that had no clear association with infections except for a transient fever episode 1 month earlier. Isolation of Staphylococcus aureus from an open-surgery sample identified the cause of the mass. The patient achieved excellent recovery with no recurrence even after 8 years of follow-up. To our knowledge, this rare pattern of infection highlights the importance of early diagnosis in combination with a surgical approach as an effective diagnosis and treatment approach that provided a good outcome.

"É difícil temer aquilo que não podemos ver": o trabalho representacional da Covid-19 e a pedagogia do medo entre vírus e animações / "It's hard to fear something we can't see": the representational work of Covid-19 and the pedagogy of fear between viruses and animacies

Resumo A mais recente pandemia, caracterizada como SARS-CoV-2, se insere em uma linhagem conhecida de patógenos virais que podem desencadear infecções respiratórias severas. Em que pese a importância de se avançar no conhecimento biomédico como forma de garantir o tratamento e a eficácia na suposta erradicação da doença, não é menos urgente refletir acerca das circunstâncias sociais que modelam essa nova situação epidemiológica. Este ensaio analisa como as representações sobre e contágio e morte imbricadas na díade saúde-doença, como fenômenos tradicionais, se revestiram de proposições morais, particularmente entre os meses de janeiro e março de 2020, quando as definições de surto, epidemia e pandemia se tornaram inextricavelmente misturadas. Naquele contexto, e a partir da criação de um tipo de dispositivo de saúde animado por imperativos afeitos à forma mais mortal da doença, a Covid-19 ganhou materialidade. Constituído na confluência de concepções étnico-racializantes, este dispositivo pedagogizou as primeiras imagens da doença, sedimentadas em uma gramática altamente visual e linguística afeitas a um medo coletivo. Examinamos que o trabalho de recepção, nomeação e enquadramento da Covid-19 dependeu de regimes de visibilidade condicionados por processos tradicionais, relativos à materialização e animação do vírus enquanto uma ameaça não só epidemiológica e social, mas política e moral.

Abstract The most recent pandemic, characterized as SARS-CoV-2, is part of a known lineage of viral pathogens that can trigger severe respiratory infections. Despite the importance of advancing biomedical knowledge as a way to guarantee treatment and effectiveness in the supposed eradication of the disease, it is no less urgent to reflect on the social circumstances that shape this new epidemiological situation. This essay analyzes how the representations of contagion and death imbricated in the health-disease dyad, as traditional phenomena, took on moral propositions, particularly between the months of January and March 2020, when the definitions of outbreak, epidemic and pandemic became inextricably mixed. In that context, and from the creation of a type of health apparatus animated by imperatives related to the deadliest form of the disease, Covid-19 gained materiality. Constituted at the confluence of ethnic-racializing conceptions, this apparatus formed the first visual and linguistic images of the disease. Finally, this article examines that the work of reception, appointment and framing of Covid-19 depended on visibility regimes conditioned by traditional processes, related to the materialization and animation of the virus as a threat not only epidemiological and social, but political and moral.

Utilization of Cumbeba (Tacinga inamoena) Residue: Drying Kinetics and Effect of Process Conditions on Antioxidant Bioactive Compounds.

The residue generated from the processing of Tacinga inamoena (cumbeba) fruit pulp represents a large amount of material that is discarded without proper application. Despite that, it is a raw material that is source of ascorbic acid, carotenoids and phenolic compounds, which are valued in nutraceutical diets for allegedly combating free radicals generated in metabolism. This research paper presents a study focused on the mathematical modeling of drying kinetics and the effect of the process on the level of bioactive of cumbeba residue. The experiments of cumbeba residue drying (untreated or whole residue (WR), crushed residue (CR) and residue in the form of foam (FR)) were carried out in a fixed-bed dryer at four air temperatures (50, 60, 70 and 80 °C). Effective water diffusivity (Deff) was determined by the inverse method and its dependence on temperature was described by an Arrhenius-type equation. It was observed that, regardless of the type of pretreatment, the increase in air temperature resulted in higher rate of water removal. The Midilli model showed better simulation of cumbeba residue drying kinetics than the other models tested within the experimental temperature range studied. Effective water diffusivity (Deff) ranged from 6.4890 to 11.1900 × 10-6 m2/s, 2.9285 to 12.754 × 10-9 m2/s and 1.5393 × 10-8 to 12.4270 × 10-6 m2/s with activation energy of 22.3078, 46.7115 and 58.0736 kJ/mol within the temperature range of 50-80 °C obtained for the whole cumbeba, crushed cumbeba and cumbeba residue in the form of foam, respectively. In relation to bioactive compounds, it was observed that for a fixed temperature the whole residue had higher retention of bioactive compounds, especially phenolic compounds, whereas the crushed residue and the residue in the form of foam had intermediate and lower levels, respectively. This study provides evidence that cumbeba residue in its whole form can be used for the recovery of natural antioxidant bioactive compounds, mainly phenolic compounds, with the possibility of application in the food and pharmaceutical industries.

Sources and management of nitrogen before or after irrigation on the winter wheat and bean production / Fontes de nitrogênio e manejo antes ou após a irrigação nas culturas do trigo e feijoeiro "de inverno"

Studies that demonstrate the effects of sources of nitrogen (N) applied before or after irrigation on the yield of winter crops are limited in literature. In this sense, the objective of this study was to compare the effect of sources of N applied immediately before or after 13 mm irrigation of wheat and bean winter crops. It was used a randomized complete block design, with 4 replicates, in a 5 × 2 + 1 factorial scheme, and 11 treatments consisted of five N sources: urea, polymer-coated urea, urea + ammonium sulfate, ammonium sulfate, and ammonium nitrate and a control treatment (without N fertilization). For wheat, although ammonium nitrate provided great N content in the leaves, the grain yield was lower due to the lodging of the plants; since the application of N either before or after irrigation did not influence the grain yield. Regarding the bean, N fertilization increased productivity, but there were no differences among N sources and, despite the greater N content in the leaves observed with the N supply before irrigation the greatest grain yield was observed when N was applied after the irrigation.

Estudos que demonstram os efeitos de fontes de nitrogênio (N) aplicadas antes ou após a irrigação na produtividade das culturas de inverno são limitados na literatura. Neste sentido, o objetivo deste trabalho foi comparar o efeito de fontes de N aplicadas imediatamente antes ou após a irrigação de 13 mm nas culturas do trigo e feijão de inverno. Utilizou-se o delineamento de blocos casualizados, com 4 repetições, em esquema fatorial incompleto 5 × 2 + 1, sendo 11 tratamentos com cinco fontes de N: ureia, ureia revestida com polímero, ureia + sulfato de amônio, sulfato de amônio e nitrato de amônio e um tratamento controle (sem adubação nitrogenada). Para o trigo, embora o nitrato de amônio tenha proporcionado maior teor de N nas folhas, a produtividade de grãos foi menor devido ao acamamento das plantas; já a aplicação de N antes ou após a irrigação não influenciou a produtividade de grãos. Com relação ao feijão, a adubação nitrogenada aumentou a produtividade, mas não houve diferenças entre as fontes de N e, apesar do maior teor de N nas folhas observadas com o suprimento de N antes da irrigação, a maior produtividade de grãos foi observada com a adubação após a irrigação.

Homosexuality and biomarkers of aging in the production of gerontological knowledge by American, British, and Brazilian authors.

This study reviewed articles originated in Brazil, in the United Kingdom, and in the United States from 1970 to September 2018 in the Web of Science database. Text mining techniques were used, and a predominantly qualitative analysis was performed, including correspondence analysis and sentiment analysis using the R Software (version 3.5.0) tools. Results show a repathologization of homosexuality in the gerontological knowledge production. This includes studies performed in 51 areas of knowledge in the three countries. That was followed by the depsychiatrization of homosexuality during the peak of deaths caused by AIDS, and its consequent recognition as an epidemiological threat. The article concludes reviewing the collected biomarkers, such as "sexual", "risk", "MSM", and "HIV/AIDS", which prove the progressive impact of sexual panic in gerontology studies and also associates AIDS with masculine homosexuality.

Homosexual desire after AIDS: an analysis of the criteria adopted by men in the search for same sex partners. / O desejo homossexual após a AIDS: uma análise sobre os critérios acionados por homens na busca por parceiros do mesmo sexo.

This article analyzes changes and continuities in partner search criteria by homosexual men considering the impact of the HIV-AIDS epidemic in the city of São Paulo, Brazil. Thus, it compares two different historical moments: between 1979 and 1981 (pre-epidemic) and 2015 to 2017 (post-epidemic). In the first period, the source incorporated 120 classified ads collected from the Lampião da Esquina newspaper and in the second period, the preferences and criteria used to search for partners were analyzed using geolocalized applications, based on 120 online profiles. The data show that that between 1979-1981 the search for "discreet" partners took place, while the sexual panic created in the deadliest period of the AIDS epidemic boosted the use of the Internet in search of partners less likely to be infected with HIV, the "out of the (gay) scene". Since then, the search for "discreet and out of the (gay) scene" has consolidated itself by shaping the body's ideals and conduct that shape the current São Paulo online sex market in which part of the homosexuals take part.

Este artigo analisa as mudanças e continuidades nos critérios de busca de parceiros por homens homossexuais a partir do impacto da epidemia de HIV-aids na cidade de São Paulo. Assim, compara dois momentos históricos distintos: entre 1979 e 1981 (pré-epidemia) e 2015 a 2017 (pós-epidemia). No primeiro período, a fonte incorporou 120 classificados recolhidos do jornal Lampião da Esquina e no segundo período, foram analisadas as preferências e os critérios acionados na busca por parceiros realizada com o uso de aplicativos geolocalizados, a partir de 120 perfis on-line. Os dados permitem afirmar que, já na virada da década de 1970 para a de 1980, existia a busca pelo "discreto" enquanto o pânico sexual criado em meio ao período mais mortal da epidemia de AIDS impulsionou o uso de Internet por homossexuais em busca de parceiros com menor probabilidade de estarem contaminados com o HIV, o "fora do meio (gay)". Desde então, a busca pelo "discreto e fora do meio" se consolidou moldando ideais corporais e de conduta que regem o atual mercado sexual on-line em que se insere parte dos homossexuais paulistanos.

Since then, the search for "discreet and out of the (gay) scene" has consolidated itself by shaping the body's ideals and conduct that shape the current São Paulo online sex market in which part of the homosexuals take part.

Homosexuality and biomarkers of aging in the production of gerontological knowledge by American, British, and Brazilian authors / Homossexualidade e biomarcadores de envelhecimento na produção de conhecimento gerontológico por autores estadunidenses, britânicos e brasileiros / Homosexualidad y biomarcadores de envejecimiento en la producción de conocimiento gerontológico, según autores estadounidenses, británicos y brasileños

Abstract: This study reviewed articles originated in Brazil, in the United Kingdom, and in the United States from 1970 to September 2018 in the Web of Science database. Text mining techniques were used, and a predominantly qualitative analysis was performed, including correspondence analysis and sentiment analysis using the R Software (version 3.5.0) tools. Results show a repathologization of homosexuality in the gerontological knowledge production. This includes studies performed in 51 areas of knowledge in the three countries. That was followed by the depsychiatrization of homosexuality during the peak of deaths caused by AIDS, and its consequent recognition as an epidemiological threat. The article concludes reviewing the collected biomarkers, such as "sexual", "risk", "MSM", and "HIV/AIDS", which prove the progressive impact of sexual panic in gerontology studies and also associates AIDS with masculine homosexuality.

Resumo: O estudo faz uma revisão de artigos publicados por autores brasileiros, britânicos e estadunidenses entre 1970 e setembro de 2018 na base de dados Web of Science. Foram utilizadas técnicas de prospecção de textos, com uma análise predominantemente qualitativa, inclusive análise de correspondência e de sentimentos, usando ferramentas do software R (versão 3.5.0). Os resultados revelam a repatologização da homossexualidade na produção de conhecimento gerontológico, incluindo estudos realizados em 51 áreas de conhecimento nos três países. Seguiu-se a despsiquiatrização da homossexualidade durante o auge de óbitos provocados pela aids e o reconhecimento desta como ameaça epidemiológica. O artigo conclui com uma revisão dos biomarcadores coletados, como "sexual", "risco", "HSH" e "HIV/aids", comprovando o impacto progressivo do pânico sexual sobre os estudos de gerontologia, além de associar a aids à homossexualidade masculina.

Resumen: Este estudio revisó artículos realizados en Brasil, Reino Unido y en los Estados Unidos desde 1970 a septiembre de 2018 en la base de datos Web of Science. Se utilizaron técnicas de mineración de textos, y predominantemente se realizó un análisis cualitativo, incluyendo análisis de correspondencia y análisis de opiniones, usando las herramientas del R Software (version 3.5.0). Los resultados muestran la repatologización de la homosexualidad en la producción de conocimiento gerontológico. Esto incluye estudios realizados en 51 aéreas de conocimiento en los tres países. A todo ello, le siguió la desiquiatrización de la homosexualidad, durante el pico de muertes causado por el SIDA, y su consiguiente reconocimiento como amenaza epidemiológica. Este artículo finaliza revisando los biomarcadores recogidos, tales como: "sexual", "riesgo", "HSH", y "VIH/SIDA", lo que prueba el progresivo impacto del pánico sexual en los estudios de gerontología, así como los asociados al SIDA, con la homosexualidad masculina.

Remote setting of Nodipecten nodosus (Linnaeus 1758) larvae / Assentamento remoto de larvas Nodipecten nodosus (Linnaeus 1758)

The present study aimed to evaluate the growth and survival of Nodipecten nodosus larvae grown in a remote settlement system. Two forms of transport were tested, one in a humid/wet, environment and one submerged in seawater, with a control treatment maintained at the Laboratory of Marine Mollusks (LMM). After transport treatments, individuals were populated simultaneously inside floating boxes directly at sea and in containers under controlled conditions in the Laboratory of the Experimental Center for Mariculture (CEMAR). No statistical differences were observed in larval survival relative to the method of transport in the different experiments. However, statistical differences were observed in Evaluation 1 (EVA1) for the survival and growth of larvae transported in submerged seawater and settled in the laboratory. No statistical difference was observed between the control and either wet/humid or submerged treatments in EVA2. The survival values in the control treatment in EVA3 were higher (p<0.05) in relation to the wet and submerged treatments cultivated in the laboratory. It was not possible to observe the presence of pre-seeds in treatments grown at sea. Is possible to transport larvae for 6 hours of travel to be settled in controlled conditions far from their place of origin.(AU)

Este estudo teve como objetivo avaliar o crescimento e a sobrevivência de larvas de vieiras Nodipecten nodosus cultivadas em sistema remoto de assentamento. Foram testadas duas formas de transporte, úmido e submerso em água do mar com um tratamento controle mantido no Laboratório de Moluscos Marinhos (LMM). Após serem expostos aos tratamentos de transporte os animais foram povoados dentro de caixas flutuantes, diretamente no mar e em recipientes em condições controladas no Laboratório do Centro Experimental de Maricultura (CEMAR). Não houve diferença estatística na sobrevivência das larvas em relação ao método de transporte nos diferentes experimentos. Observou-se diferenças estatísticas (p<0,05), na avaliação 1 (EVA1), para a sobrevivência e crescimento de larvas transportadas em meio submerso e assentadas no laboratório. Entretanto, não foi observada diferença estatística entre o tratamento controle, úmido e submerso na EVA2. Os valores de sobrevivência no tratamento controle na EVA3 foram superiores (p<0,05) em relação aos tratamentos úmido e submersos cultivados em laboratório. Não foi possível observar presença de pré-sementes nos tratamentos cultivados no mar. Conclui-se que é possível transportar larvas por seis horas de viagem para serem assentadas em condições controladas distante do seu local de origem.(AU)
