Actitudes ante la muerte en profesionales de enfermería latinoamericanos: una revisión integrativa

Introducción: La muerte es parte de los tabúes sociales existentes y puede fomentar actitudes que distan de su abordaje explícito en relación con los cuidados. Objetivo: Analizar las actitudes ante la muerte en profesionales de enfermería de acuerdo con las publicaciones científicas en el contexto latinoamericano en el período 2018 a 2022. Metodología: Se realizó una revisión de literatura integrativa de las publicaciones científicas latinoamericanas respecto de las actitudes ante la muerte en el contexto de la enfermería, empleando los siguientes términos estandarizados: actitud, muerte, enfermería y cuidados de enfermería. Se incluyeron 8 artículos publicados en el período definido, en idioma español y portugués, en los que se abordó explícitamente la temática de la revisión. La información de los artículos fue analizada tomando como referencia los conceptos de la teoría de las transiciones. Resultados: Se encontraron diseños tanto cuantitativos (50 %) como cualitativos (50 %), elaborados en su totalidad en el ámbito hospitalario. Los principales resultados dan cuenta del predominio de la indiferencia ante la muerte en el contexto de los cuidados. En relación con la teoría de las transiciones, la mayoría de los artículos abordan las condiciones en que estas se dan, además de los conceptos de terapéutica de enfermería y patrones de respuesta. Conclusiones: La producción de investigaciones sobre la actitud ante la muerte en profesionales de enfermería es escasa en Latinoamérica. Las experiencias de pérdidas cercanas, la capacitación y el soporte institucional son la base para contribuir a una mejor actitud hacia la muerte

Introduction: Death is part of the existing social taboos and can foster attitudes that are far from its explicit approach in relation to care. Objective: To analyze attitudes towards death in nursing professionals according to scientific publications in the Latin American context in the period 2018 to 2022. Methodology: An integrative literature review was conducted of Latin American scientific publications regarding attitudes towards death in the context of Nursing, using the following standardized terms: attitude, death, nursing and nursing care. Eight articles published in the defined period were included, in Spanish and Portuguese, in which the subject of the review was explicitly addressed. The information in the articles was analyzed using the concepts of the theory of transitions as a reference. Results: Both quantitative (50 %) and qualitative (50 %) designs were found, all of them elaborated in the hospital setting. The main results show the predominance of indifference to death in the context of care. In relation to the theory of transitions, most of the articles address the conditions under which these occur, in addition to the concepts of nursing therapeutics and response patterns. Conclusions: The production of research on the attitude towards death in nursing professionals is scarce in Latin America. Experiences of close losses, training and institutional support are the basis for contributing to a better attitude towards death

Racial Disparities in Medication Use During Pregnancy: Results from the NISAMI Cohort.

Purpose: This study aimed to evaluate racial disparities in medication use and associated factors among pregnant women receiving prenatal care at Brazilian Unified Health System primary care health units in the northeast region. Patients and Methods: A total of 1058 pregnant women in the NISAMI Cohort were interviewed between June 2012 and February 2014. Medicines used during pregnancy were classified according to the Anatomical Therapeutic Chemical (ATC) classification system and ANVISA pregnancy risk categories. Prevalence ratios (crude and adjusted) and 95% confidence intervals (CIs) were estimated using Poisson regression with robust error variance. All analyses were stratified by race (Asian, black, brown/mixed, Brazilian indigenous, and white). Results: Approximately 84% of the pregnant women used at least one medication, with a lower proportion among white women. The most reported medications were antianemic preparations (71.08%; 95% CI 68.27-73.72%), analgesics (21.74%; 95% CI 19.36-24.32%), and drugs for functional gastrointestinal disorders (18.81%; 95% CI 16.57-21.28%). Approximately 29% of women took potentially risky medications during pregnancy, with a higher prevalence among Asian and white women. Factors associated with medication use during pregnancy include a greater number of prenatal consultations, higher education levels, health problems, and smoking. In addition, maternal age above 25 years, smoking status, and two or more previous pregnancies were associated with potentially risky medication use during pregnancy. Conclusion: A high prevalence of medication use during pregnancy was found; however, this prevalence was lower among white women. Nonetheless, black and brown women used antianemic preparations less frequently. This finding suggests that race is a factor of inequity in prenatal care, demanding public policies to mitigate it.

The hydrogen sulfide donor 4-carboxyphenyl-isothiocyanate decreases blood pressure and promotes cardioprotective effect through reduction of oxidative stress and nuclear factor kappa B/matrix metalloproteinase (MMP)-2 axis in hypertension.

AIMS: Our aim was to evaluate whether the hydrogen sulfide (H2S) donor, 4-carboxyphenyl-isothiocyanate (4-CPI), exerts cardioprotective effect in the two kidney- one clip (2K-1C) rats through oxidative stress and MMP-2 activity attenuation and compare it with the classical H2S donor, Sodium Hydrosulfide (NaHS). MATERIALS AND METHODS: Renovascular hypertension (two kidneys-one clip; 2K-1C) was surgically induced in male Wistar rats. After two weeks, normotensive (2K) and hypertensive rats were intraperitoneally treated with vehicle (0.6 % dimethyl sulfoxide), NaHS (0.24 mg/Kg/day) or with 4-CPI (0.24 mg/Kg/day), for more 4 weeks. Systolic blood pressure (SBP) was evaluated weekly by tail-cuff plethysmography. Heart function was assessed by using the Millar catheter. Cardiac hypertrophy and fibrosis were evaluated by hematoxylin and eosin, and Picrosirius Red staining, respectively. The H2S was analyzed using WSP-1 fluorimetry and the cardiac oxidative stress was measured by lucigenin chemiluminescence and Amplex Red. MMP-2 activity was measured by in-gel gelatin or in situ zymography assays. Nox1, gp91phox, MMP-2 and the phospho-p65 subunit (Serine 279) nuclear factor kappa B (NF-κB) levels were evaluated by Western blotting. KEY FINDINGS: 4-CPI reduced blood pressure in hypertensive rats, decreased cardiac remodeling and promoted cardioprotection through the enhancement of cardiac H2S levels. An attenuation of oxidative stress, with inactivation of the p65-NF-κB/MMP-2 axis was similarly observed after NaHS or 4-CPI treatment in 2K-1C hypertension. SIGNIFICANCE: H2S is a mediator that promotes cardioprotective effects and decreases blood pressure, and 4-CPI seems to be a good candidate to reverse the maladaptive remodeling and cardiac dysfunction in renovascular hypertension.

Periodontitis and systemic parameters in chronic kidney disease: Systematic review and meta-analysis.

OBJECTIVE: To perform a systematic review with meta-analysis to assess recent scientific evidence on the association between periodontitis and systemic parameters/conditions in individuals with chronic kidney disease (CKD). MATERIALS AND METHODS: The search for studies was performed in MedLine/PubMed, Scopus, Web of Science, and BIREME databases. Reference lists of selected articles were also searched. Studies with different epidemiological designs evaluating the influence of exposure to periodontitis on serum markers and mortality in individuals with CKD were eligible for inclusion. Three independent reviewers performed the article selection and data extraction. The assessment of methodological quality used the adapted Newcastle Ottawa Scale. Random effects meta-analysis was performed to calculate association measurements and 95% confidence intervals. RESULTS: In total, 3053 records were identified in the database search, with only 25 studies meeting the eligibility criteria and, of these, 10 studies contributed data for meta-analysis. Using a random-effects model, periodontitis was associated with hypoalbuminemia (PRunadjusted = 2.47; 95%CI:1.43-4.26), with high levels of C-reactive protein (PRunadjusted = 1.35; 95%CI%:1.12-1.64), death from cardiovascular disease (RRunadjusted = 2.29; 95%CI:1.67-3.15) and death from all causes (RRunadjusted = 1.73; 95%CI:1.32-2.27). CONCLUSIONS: The findings of this review validated a positive association between periodontitis and serum markers and mortality data in individuals with CKD.

Development, Survival and Reproduction of Nezara viridula (Hemiptera: Pentatomidae) in Sesame Cultivars and Implications for the Management.

Sesame, an oilseed plant with multiple applications, is susceptible to infestations by the stink bug Nezara viridula (Linnaeus, 1758) (Hemiptera: Pentatomidae). This pest suctions the seeds of this plant and injects toxins into them. Possible sources of resistance on sesame cultivars are important to manage this bug. The objective of this study was to evaluate the biological aspects of N. viridula fed on three sesame cultivars aiming to select possible resistance sources for integrated pest management (IPM) programs of this stinkbug. The experimental design used randomized blocks with three treatments and four replications, each with newly emerged N. viridula nymphs fed with sesame capsules of the cultivars BRS Anahí (T1), BRS Morena (T2) and BRS Seda (T3). Two to three green sesame capsules were supplied every two days per group of ten N. viridula nymphs as one replication until the beginning of the adult stage. Adults of this stinkbug were fed in the same manner as its nymphs but with mature sesame capsules until the end of the observations. Survival during each of the five instars and of the nymph stage of N. viridula with green sesame capsules was similar between cultivars, but the duration of the nymph stage was shorter with green capsules of the BRS Morena than with those of the BRS Anahí. The oviposition period, number of egg masses and eggs per female, and the percentage of nymphs hatched were higher with mature capsules of the sesame cultivar BRS Anahí and lower with the others. Nymphs did not hatch from eggs deposited by females fed mature seed capsules of the sesame cultivar BRS Morena, which may indicate a source of resistance against this stinkbug in this cultivar. The worldwide importance of N. viridula to sesame cultivation makes these results useful for breeding programs of this plant aiming to develop genotypes resistant to this bug. In addition, the BRS Morena is a cultivar already commercially available and can be recommended in places where there is a history of incidence of N. viridula, aiming to manage the populations of this pest.

Interspecific insect relationships on Terminalia argentea (Myrtales: Combretaceae) trees in the Cerrado biome.

Terminalia argentea Mart. (Combretaceae), native to Brazil, is used in habitat restoration programs. Arthropods are bioindicators because their populations reflect changes in the environment. We evaluated the recovery of a degraded area by using ecological indices and analyzing arthropod interactions on T. argentea plants. The richness and diversity of sap-sucking Hemiptera and the abundance of tending ants and Sternorrhyncha predators increased with the number of T. argentea leaves. The correlation of the abundance of tending ants and Sternorrhyncha predators was positive with that of the sap-sucking Hemiptera, and the abundance of Sternorrhyncha predators was negative with that of tending ants and sap-sucking Hemiptera. The positive correlation between the abundance, richness, and diversity of insect groups and numbers of T. argentea leaves is an example of the bottom-up regulation mechanism, with the population dynamics of the lower trophic levels dictating those of higher trophic levels. The contribution of T. argentea, a host plant of many arthropods, to the recovery of ecological relationships between organisms in degraded ecosystems is important.

Catastrophizing is associated with pain-related disability in temporomandibular disorders.

This study aimed to evaluate the association of pain-related disability with biopsychosocial factors in temporomandibular disorders (TMD) patients. The study was carried out at the Orofacial Pain Outpatient Clinic of the State University of Feira de Santana, Bahia, from September 2018 to March 2020. The sociodemographic aspects, TMD subtypes, presence of pain-induced disability, pressure pain threshold, perceived stress, anxiety, depression, and catastrophizing were evaluated in 61 patients. The studied variables were compared between patients with and without pain-induced disability. Crude and adjusted logistic regression were performed to obtain estimates of odds ratios (OR) and 95% confidence intervals. With the exception of catastrophizing, there was no association between the biopsychosocial factors and pain-induced disability. The presence of catastrophizing increased the chance of having chronic pain-induced disability by 4.02 times. The results of this study indicate a strong association between pain catastrophizing and disability in individuals with chronic painful TMD.

Gamma radiation effect on the chemical, mechanical and thermal properties of PCL/MCM-48-PVA nanocomposite films.

In this work, poly (vinyl alcohol) (PVA) was employed to produce a Mesoporous Composition of Matter-48 Modified (MCM-48-M or MCM-48-PVA). After surface modification, MCM-48-M was used to produce nanocomposite (NC) films with polycaprolactone (PCL) as a matrix at room temperature. PCL and MCM-48 nanoparticles (NPs) were chosen due to their great biocompatibility and low toxicity. However, MCM-48-M is more compatible with PCL than MCM-48. NC films were sterilized by gamma radiation with a dose of 25 kGy and characterized by experimental techniques to investigate their chemical, mechanical (tensile) and thermal properties. Scanning electron microscopy (SEM) and transmission electronic microscopy (TEM) results indicated that MCM-48-M exhibited a random distribution in the PCL matrix. The PCL chemical structure was preserved in NC films as described by Fourier transform infrared (FT-IR) spectroscopy as well as the tensile and thermal properties of NC films. FT-IR and thermogravimetric analysis (TGA) results showed surface modification. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) showed that crystalline symmetries were preserved and the crystallinity of NC films had small variations in all samples before and after irradiation, respectively. But, our results did not indicate major changes showing that this method is successful for the sterilization of PCL/MCM-48-PVA NC films.

Morphology and Morphometry of the Reproductive Tract of the Cotton Boll Weevil after Prolonged Feeding on Alternative Diets.

Anthonomus grandis Boheman (Coleoptera: Curculionidae) survives on alternative diets; however, this induces reproductive diapause. The objective was to evaluate the morphology and morphometry of the reproductive tract of this weevil after feeding on alternative diets. The experimental design was completely randomized with 160 replications and treatments arranged in a factorial design 3 × 3, represented by A. grandis adults fed on 3 food types (fragments of banana (T1) or orange (T2) endocarp, or with cotton squares of cultivar BRS 286 (T3, control)) and three evaluation periods (30, 60, and 90 days) and after each of these periods they were fed with cotton squares for 10 days. The reproductive tract of 100% of A. grandis females fed banana endocarp, orange endocarp, and cotton squares for 30 and 60 days and then cotton squares were morphologically adequate for reproduction, and after 90 days, only 50% of those fed cotton squares were in this condition. The length of the ovarioles and the width of the mature oocyte were greater for A. grandis fed on cotton squares and smaller in those with banana and orange endocarps. Histological sections reveal that male testes even with strong degenerative signals are already producing spermatozoa. On the other hand, females displayed ovaries with nurse cells in the tropharium and some maturing oocytes in the vitellarium. The body length was longer and the testis area and diameter smaller in males fed on cotton squares than in those with banana and orange endocarp. Anthonomus grandis females fed for ≥90 days with alternative food sources do not recover the functionality of their reproductive tract, even after consuming, for 10 days, a diet that favors reproduction. On the other hand, the males remain with their reproductive organs functional with this condition.

New records of Ceratocampinae (Lepidoptera: Saturniidae) species from the Cerrado of Maranhão, Brazil / Novos registros de espécies de Ceratocampinae (Lepidoptera: Saturniidae) para o Cerrado do Maranhão, Brasil

Abstract Ceratocampinae (Lepidoptera: Saturniidae) is the second most diverse subfamily of Saturniidae with 300 species described in 30 genera from southern Canada to northern Argentina. Species of this subfamily are widely distributed in Southeast Brazil, with many endemics to the Cerrado, and important as indicators of ecosystem quality. Specimens of Ceratocampinae were collected in the Parque Estadual do Mirador, Maranhão state, Brazil. Adeloneivaia acuta (Schaus, 1896), Adeloneivaia schubarti Barros & O. Mielke, 1970, Eacles penelope (Cramer, 1775) and Megaceresa pulchra (Bouvier, 1923) are recorded for the first time in Maranhão state and Northeast Brazil and Eacles fairchildi May & Oiticica, 1941, only for Maranhão. The record of five Ceratocampinae (Saturniidae) species increases the knowledge on the diversity and the importance of preserving those of this subfamily in the Cerrado biome of Maranhão state and the Northeast region of Brazil.

Educação física que não escolhe, acolhe / La educación física que no elige, da la bienvenida / Physical education that does not choose welcomes

O objetivo deste estudo é compreender como professores de Educação Física que atuam inspirados pelo currículo cultural abordam as diferenças em suas práticas pedagógicas. Trata-se de um estudo qualitativo, com enfoque etnometodológico e norteado pela teoria queer. Participaram da pesquisa quatro professores de Educação Física do Colégio Pedro II. O método de coleta de dados foi a entrevista semiestruturada. Utilizaram-se os cinco conceitos-chave da etnometodologia como categorias a priori para auxiliar na compreensão e análise dos dados. Justifica-se este estudo em função dos vários caminhos didático-pedagógicos culturalmente orientados que impedem o devir da imprevisibilidade das diferenças. Concluímos que o aporte teórico queer potencializa o poder de reflexão e contestação do currículo cultural de Educação Física, pois evita que ações docentes a favor de identidades e grupos marginalizados se transformem em novos essencialismos.(AU)

The objective of this study is to understand how Physical Education teachers who work inspired by the cultural curriculum approach the differences in their pedagogical practices. This is a qualitative study, with an ethnomethodological approach and guided by queer theory. Four Physical Education teachers from Colégio Pedro II participated in the research. The data collection method was a semi-structured interview. The five key concepts of ethnomethodology were used as a priori categories to help understand and analyze the data. This study is justified by the fact that several culturally oriented didactic-pedagogical paths impede the becoming of unpredictability of differences. We conclude that the queer theoretical framework enhances the power of reflection and contestation of the cultural curriculum of Physical Education, because it prevents that teaching actions in favor of marginalized identities and groups become new essentialisms.(AU)

Survival of young and elderly adults with oral squamous cell carcinoma in a population in northeastern Brazil

To compare the profile and overall survival of young adults and elderly people diagnosed with SCC. Methods: A retrospective study was carried out at a High Complexity Oncology Unit, between 2010 and 2016. A descriptive analysis, a bivariate analysis using the chi-square and Fisher's exact test and the Kaplan-Meier estimator were performed. The predictor variables were tested using the log-rank test and those with statistical significance and the literature were maintained for the Cox regression model. Results: 282 cases of SCC were recorded, with only 12.4% diagnosed in young adults. The profile was similar between groups, with the majority of cases of the disease occurring in males, smokers and alcohol consumers. The lesions predominantly located on the tongue and were diagnosed in an advanced stage of the disease, resulting in 35.7% of deaths. The median survival time was 30 months in the elderly and 31 months in young people. In the multivariate analysis, age was not statistically significant, only staging and treatment were predictors of reduced overall survival. Conclusion: Tumor staging, and treatment were prognostic factors for the disease

Electronic and transport properties of new carbon nanoribbons with 5-8-5 carbon rings: tuning stability by the edge shape effect.

We predicted the existence of five carbon nanoribbons based on POPGraphene, by first-principles calculations. We investigated the role of the shape of the edges in stability, structural, electronic, and transport properties. Density functional theory (DFT) was implemented to relax the unit cell nanoribbons, and DFT combined with non-equilibrium Greens functions was used to obtain the transport properties of molecular devices. Our results strongly suggest that all nanoribbons are stable, and can be feasibly obtained through experiment. Furthermore, the edge termination with pentarings is an important factor in the stability of nanoribbons. The electronic properties show that the three zigzag nanoribbons have a metallic behavior and the two armchair ones are semiconductors, but with a very tiny indirect bandgap of 0.053 eV and 0.050 eV. The transport properties show that the presence of partially filled steep bands crossing deeper into the Fermi level triggers high conductivity in molecular devices and the presence of flat bands decreases the device conductivity. The presence of sub-bandgap regions triggers the rise of negative differential resistance (NDR) regions in the device operation. The molecular device behavior is strongly dependent on the shape of the edges, presenting characteristics of field effect transistors (FETs), lighting emitting diodes (LEDs), or resonant tunneling diodes (RTDs), depending on the edge termination and operation range.

Impact of plot size on tropical forest structure and diversity estimation / Impacto del tamaño de la parcela en la estructura y estimación de la diversidad de los bosques tropicales

Abstract Introduction: Inventories are essential for forest management, but, in the Amazon region, the absence of standardization produces information loss, low accuracy, and inconsistent measurements. This prevents valid comparisons and compromises the use of information in networks and software. Sampling unit size is of key importance in the inventory of native forests, particularly regarding accuracy and costs. Objective: To identify a plot size that provides adequate precision for dendrometric parameters in the Amazon. Methods: In Cotriguaçu, Mato Grosso, Brazil, we tested four plot sizes with six repetitions each: 2 500, 5 000, 7 500, and 10 000 m². We measured diameter at breast height, population density, basal area, and biomass. We applied Shannon and Jaccard indexes; Weibull 2P and Gamma functions to fit the diametric distribution; and the Akaike Information Criterion for the best model. Results: There was a directly proportional relationship between plot area and population similarity, but diversity did not indicate significant alterations. Plot size did not affect dendrometric attributes and diametric distribution. Larger plot areas led to lower coefficients of variation and smaller confidence intervals. The Gamma function was the best model to represent the distributions of different plot sizes. Conclusions: For similar forests, we recommend the 2 500 m² plot to evaluate diameter at breast height, population density, basal area, and biomass.

Resumen Introducción: Los inventarios son fundamentales para la gestión forestal, pero en la Amazonía la ausencia de estandarización produce pérdida de información, baja precisión y mediciones inconsistentes. Esto impide comparaciones válidas y compromete el uso de información en redes y programas. El tamaño de la unidad de muestreo es de importancia clave en el inventario de bosques nativos, particularmente en lo que respecta a la precisión y los costos. Objetivo: Identificar un tamaño de parcela que proporcione una precisión adecuada para los parámetros dendrométricos en la Amazonía. Métodos: En Cotriguaçu, Mato Grosso, Brasil, probamos cuatro tamaños de parcela con seis repeticiones cada una: 2 500, 5 000, 7 500 y 10 000 m². Medimos diámetro a la altura del pecho, densidad de población, área basal y biomasa. Se aplicaron los índices de Shannon y Jaccard; Funciones Weibull 2P y Gamma para adaptarse a la distribución diametral; y el Criterio de Información de Akaike para el mejor modelo. Resultados: Hubo una relación directamente proporcional entre el área de parcela y la similitud poblacional, pero la diversidad no indicó alteraciones significativas. El tamaño de la parcela no afectó los atributos dendrológicos y la distribución diametral. Las áreas de parcela más grandes dieron lugar a coeficientes de variación más bajos e intervalos de confianza más pequeños. La función Gamma fue el mejor modelo para representar las distribuciones de diferentes tamaños de parcela. Conclusiones: Para bosques similares, recomendamos la parcela de 2 500 m² para evaluar diámetro a la altura del pecho, densidad de población, área basal y biomasa.

Sífilis e HIV/aids nas regiões de saúde da Bahia: uma abordagem ecológica / Syphilisa and HIV/AIDS in the health regions of Bahia: an ecological approach / Sífilis y VIH/sida en las regiones de salud de Bahía: un enfoque ecológico

Este estudo tem como objetivo analisar as hospitalizações por sífilis e HIV/aids nas regiões de saúde da Bahia, segundo aspectos temporais e espaciais, no período de 2008 a 2020. Trata-se de um estudo ecológico misto, realizado com dados de internações do Sistema de Informações Hospitalares (SIH). Os aspectos populacionais e de raça/cor foram obtidos do Instituto Brasileiro de Geografia e Estatística (IBGE). A análise descritiva dos dados e a estimativa de tendência temporal foram executadas por meio do modelo de regressão linear simples com correção de Prais-Winsten. Houve 372 internações por sífilis, com prevalência entre os jovens de 18 a 28 anos (32,5%) e da raça/cor negra (89,6%). As maiores taxas de sífilis foram encontradas nas regiões de saúde de Itabuna, Ilhéus, Paulo Afonso e Salvador. Quanto à tendência temporal, o comportamento da sífilis foi estatisticamente significante (p-valor < 0,05). Para HIV/aids, foram contabilizadas 10.281 internações, com destaque para os sujeitos de 29 a 39 anos (39,0%) e para a raça/cor negra (86,8%). Houve prevalência das taxas médias nas regiões de Salvador, Camaçari, Teixeira de Freitas e Seabra. Porém, não houve significância estatística para a tendência temporal de HIV/aids (p-valor > 0,05). Nota-se a vulnerabilidade dos jovens negros em relação às infecções estudadas nas regiões de saúde da Bahia. Esses achados podem ser relacionados ao comportamento sexual, bem como à falta de acesso a informações, métodos de prevenção e serviços de saúde a partir da atenção básica.

This study analyzes syphilis and HIV/AIDS hospitalizations in the Health Regions of Bahia, according to temporal and spatial aspects, from 2008 to 2020. A mixed ecological research was conducted using hospitalization data collected from the Information System Hospital (SIH). Population and race/ethnicity data were obtained from the Brazilian Institute of Geography and Statistics (IBGE). Descriptive data analysis and temporal trend estimation were performed by simple linear regression model with Prais-Winsten correction. From 2008 to 2020, the SIH recorded 372 hospitalizations for syphilis, especially among black youth (89.6%) aged 18 to 28 years (32.5%). The health regions of Itabuna, Ilhéus, Paulo Afonso and Salvador presented the highest syphilis rates. As for the temporal trend, syphilis showed a statistically significant behavior (p-value < 0.05). Regarding HIV/AIDS, the SIH recorded 10,281 admissions, mainly among black adults (86.8%) aged 29 to 39 years (39.0%). The health regions of Salvador, Camaçari, Teixeira de Freitas and Seabra presented mean HIV/AIDS rates. However, the temporal trend of HIV/AIDS showed no statistical significance (p-value > 0.05). Such results point to the vulnerability of black youth to syphilis and HIV/AIDS infections in the Health Regions of Bahia. These findings can be explained by the patient's sexual behavior, as well as the lack of access to information, prevention methods, and primary care services.

Abstract: Introduction: Humanized care requires the interaction between scientific knowledge and values, generating the need to particularize care, which is an essential activity in nursing. Objective: To analyze the perception of hospitalized users regarding the humanized care they receive from nursing professionals. Methodology: A quantitative, descriptive, correlational, and cross-sectional research was carried out, which included hospitalized users in the Clinical Services of Medicine, Surgery, Private, and legal representatives of patients under 18 years of age in Pediatrics, of a public hospital located in the south of Chile, with a sample of 377 participants. After the application of informed consent, it was applied a sociodemographic characterization as well as the instrument Perception of Humanized Nursing Care Behaviors - Version 3, with transcultural adaptation for the Chilean population, which was complemented with other data pertinent to the objectives of the research. Results: It was found that most of the participants recognized the nursing professional by the uniform, and despite some differences in each service, they reported satisfaction with the care received (84.6%). Aspects such as age, length of hospitalization and recognition of the nursing staff showed a statistical relation with satisfaction. Conclusions: It is necessary to implement strategies to strengthen the perception of humanized nursing care, being these aspects a contribution to the construction of an organizational climate and culture that evidences this perspective of care.

Bolsa Familia Program and Perinatal Outcomes: NISAMI Cohort.

This study aimed to assess the impact of the Bolsa Familia Program on perinatal outcomes of pregnant women. A cohort study was conducted with pregnant women supported by prenatal services at 17 Family Health Units in Bahia, Brazil. A previously tested structured questionnaire, which has sociodemographic, economic, prenatal care, lifestyle, and nutritional variables, has been used to collect data. The outcomes included premature birth and low birth weight. A hierarchical conceptual model was constructed, and logistic regression analysis was performed. From a total of 1173 pregnant women, the identified average age was 25.44 years and 34.10% had pre-gestational overweight. The non-beneficiary pregnant women presented a 1.54 (95% CI = 0.46-5.09) times higher chance of giving birth to children with low weight and a 1.03 (95% CI = 95% CI = 0.53-2.00) times chance of premature birth when compared to the beneficiary group. In the multilevel model, some variables were statistically significant, such as age between 18 and 24 years (p = 0.003), age greater than or equal to 35 years (p = 0.025), family income (p = 0.008), employment status (p = 0.010), and maternal height (p = 0.009). The Bolsa Familia Program, as an integrated strategy of social inclusion and economic development, is suggested to exert a protective effect on the health of mother-concept binomial.

Development, Survival and Reproduction of Spodoptera frugiperda (Lepidoptera: Noctuidae) Fed an Artificial Diet or on Cotton, Castor Bean and Corn Leaves.

The polyphagy of Spodoptera frugiperda (Lepidoptera: Noctuidae) renders its control difficult because variations in the phenology of host plants grown in different seasons of the year and near each other can facilitate the movement of this pest between crops. The objective of this work was to examine certain biological characteristics of S. frugiperda fed on an artificial diet or on cotton, castor bean, or corn leaves. The experimental design was in randomized blocks, with four treatments represented by S. frugiperda caterpillars fed an artificial diet (T1) or pieces of cotton (T2), castor bean (T3) or corn (T4) leaves with five replications (five caterpillars per replication). The duration and survival of the egg, larva, pre-pupa, pupa and egg-adult period and the reproductive characteristics of this insect were determined. The survival, development and reproduction data of S. frugiperda originated from individuals reared with cotton and castor bean leaves were lower than those fed on corn leaves or an artificial diet. The number of nonviable eggs laid by females originated from caterpillars fed on castor bean leaves was higher than those fed on cotton and corn leaves or an artificial diet. The very higher number of unviable S. frugiperda eggs resulting from castor leaves can reduce outbreaks of this pest in cotton and corn crops after the cultivation of that plant, or by intercropping with this plant, in the main producing regions of Brazil.

Production of engineered-biochar under different pyrolysis conditions for phosphorus removal from aqueous solution.

Phosphorus (P) recovery from wastewater through biochar is an alternative to build a sustainable circular economy and save non-renewable P reservoirs. The efficiency of cations in removing P from wastewater under different pyrolysis conditions is still lacking. We aimed at studying P adsorption and release from biochar enriched with Al3+ and Mg2+, prepared under air-limited and N2-flow pyrolysis conditions. Biochar samples were produced from pig manure (PMB) and impregnated, separately, with 20% of AlCl3 and MgCl2 solutions on both pyrolysis conditions. The materials were characterized for pH, electrical conductivity (EC), total nutrient content, ash, specific surface area (SSA), pore-volume, FTIR, XRD, and SEM-EDX. Phosphorus adsorption was studied by kinetics and adsorption isotherms, as well as desorption. The biochar impregnated with Mg2+ and produced in the muffle furnace achieved the maximum P adsorption (231 mg g-1), and 100% of the adsorbed P was released in solutions of Mehlich-1 and citric acid 2%. The pyrolysis conditions had a small or no influence on the biochar properties governing P adsorption, such as chemical functional groups, surface area, quantity and size of pores, and formation of synthetic minerals. Therefore, it is possible to produce biochar without using N2 as a carrier gas when it comes to P adsorption studies. Mechanisms of P removal comprise precipitation with cations, surface complexation, ligand exchange reactions, and electrostatic attraction on the biochar surface. Overall, Mg-impregnated biochar is a suitable matrix to remove P from aqueous media and to add value to organic residues while producing an environmentally friendly material for reuse in soils.
