Chromosomal Evolution in Aspredinidae (Teleostei, Siluriformes): Insights on Intra- and Interspecific Relationships with Related Groups.

The family Aspredinidae comprises a clade of complex systematic relationships, both from molecular and morphological approaches. In this study, conventional and molecular cytogenetic studies coupled with nucleotide sequencing were performed in 6 Aspredininae species (Amaralia hypsiura, Bunocephalus cf. aloikae, Bunocephalus amaurus, Bunocephalus aff. coracoideus, Bunocephalus verrucosus, and Platystacus cotylephorus) from different locations of the Amazon hydrographic basin. Our results showed highly divergent diploid numbers (2n) among the species, ranging from 49 to 74, including the occurrence of an XX/X0 sex chromosome system. A neighbor-joining phylogram based on the cytochrome c oxidase I (COI) showed that Bunocephalus coracoideus is not a monophyletic clade, but closely related to B. verrucosus. The karyotypic data associated with COI suggest an ancestral karyotype for Aspredinidae with a reduced 2n, composed of bi-armed chromosomes and a trend toward chromosomal fissions resulting in higher diploid number karyotypes, mainly composed of acrocentric chromosomes. Evolutionary relationships were discussed under a phylogenetic context with related species from different Siluriformes families. The karyotype features and chromosomal diversity of Aspredinidae show an amazing differentiation, making this family a remarkable model for investigating the evolutionary dynamics in siluriforms as well as in fish as a whole.

Genomic Organization of Repetitive DNAs and Differentiation of an XX/XY Sex Chromosome System in the Amazonian Puffer Fish, Colomesus asellus (Tetraodontiformes).

The genus Colomesus is the sole representative of the family Tetraodontidae in the Amazon region. Here, Colomesus asellus was analyzed using conventional and molecular cytogenetic protocols. Its diploid chromosome number is 2n = 46 with 12 meta-, 10 submeta-, 16 subtelo-, and 8 acrocentric chromosomes and a fundamental number of FN = 84. An XX/XY sex chromosome system was identified. Mapping of 18S rDNA correlated with the nucleolus organizer regions (Ag-NORs) in the short arms of the 2 X chromosomes in females and in the Y chromosome in males. C-banding revealed heterochromatin in the centromeric regions of all chromosomes, except for pair 3. Prominent sex chromosome-specific heterochromatin amplification was observed, covering the short arms of the Y chromosome almost entirely. FISH with telomeric and tropomyosin (tpm1) sequences, respectively, revealed terminal signals in all chromosomes. The analysis of extended DNA fibers confirmed the colocalization and the interspersed pattern of the telomeric and tpm1 sequences. Thus, this study highlights the remarkable evolutionary dynamism presented by the Amazonian puffer fish regarding the differentiation of a heteromorphic XY sex chromosome system and a particular sex-specific amplification of rDNA sites. This is the first record of such an association in the Tetraodontidae family.

A new multiple sex chromosome system X1X1X2X2/X1Y1X2Y2 in Siluriformes: cytogenetic characterization of Bunocephalus coracoideus (Aspredinidae).

We analyzed one Bunocephalus coracoideus population from the Negro River basin using cytogenetic techniques. The results showed a diploid number of 42 chromosomes in both sexes, with the karyotypic formula 4m + 14sm + 24a and fundamental number (FN) = 60 for females and the formula 5m + 14sm + 23a and FN = 61 for males, constituting an X1X1X2X2/X1Y1X2Y2 multiple sex chromosome system. The constitutive heterochromatin is distributed in the pericentromeric regions of most of the chromosomes, except for the sex chromosomes, of which the X1, X2, and Y1 chromosomes were euchromatic and the Y2 chromosome was partially heterochromatic. 18S rDNA mapping confirmed the presence of nucleolar organizer regions on the short arms of the fifth chromosomal pair for both sexes. The 5S rDNA is present in the terminal regions of the short arms on the 2nd, 10th, and 12th pairs and on the X2 chromosome of both sexes; however, we observed variations in the presence of these ribosomal cistrons on the Y1 chromosome, on which the cistrons are pericentromeric, and on the Y2 chromosome, on which these cistrons are present in the terminal portions of the short and long arms. Telomeric sequences are located in the terminal regions of all of the chromosomes, particularly conspicuous blocks on the 10th and 12th pairs and internal telomeric sequences in the centromeric regions of the 1st, 6th, and 9th pairs for both sexes. This work describes an new sex chromosomes system for the Siluriformes and increases our genetic knowledge of the Aspredinidae family.

Electrochemical and Bioelectrochemical Sensing Platforms for Diagnostics of COVID-19.

Rapid transmission and high mortality rates caused by the SARS-CoV-2 virus showed that the best way to fight against the pandemic was through rapid, accurate diagnosis in parallel with vaccination. In this context, several research groups around the world have endeavored to develop new diagnostic methods due to the disadvantages of the gold standard method, reverse transcriptase polymerase chain reaction (RT-PCR), in terms of cost and time consumption. Electrochemical and bioelectrochemical platforms have been important tools for overcoming the limitations of conventional diagnostic platforms, including accuracy, accessibility, portability, and response time. In this review, we report on several electrochemical sensors and biosensors developed for SARS-CoV-2 detection, presenting the concepts, fabrication, advantages, and disadvantages of the different approaches. The focus is devoted to highlighting the recent progress of electrochemical devices developed as next-generation field-deployable analytical tools as well as guiding future researchers in the manufacture of devices for disease diagnosis.

Investigation of the performance of cross-linked poly(acrylic acid) and poly(methacrylic acid) as efficient adsorbents in SPE columns for simultaneous preconcentration of tricyclic antidepressants in water samples.

A solid phase extraction-based (SPE) procedure for simultaneous preconcentration of five tricyclic antidepressants (TCAs), amitriptyline hydrochloride (AMT), nortriptyline hydrochloride (NOR), doxepin hydrochloride (DOX), imipramine hydrochloride (IMI), and clomipramine hydrochloride (CLO) from water samples with determination by HPLC-DAD is proposed. Polymers were characterized by FT-IR, SEM, and thermogravimetric analysis. SPE-based methods were carried out by the preconcentration of 320.0 mL of TCAs at pH 7.0 (buffered with 0.01 mol L-1 phosphate buffer) through 70.0 mg of adsorbent packed into a SPE cartridge, followed by elution with 1.0 mL of ACN : MeOH : acetic acid solution (45 : 45 : 10% v/v). Higher preconcentration factors were obtained ranging from 117.9 to 372.2 and 207.1 to 396.1 by using poly(MAA-co-EGDMA) and poly(AA-co-EGDMA), respectively, yielding lower limits of detection (0.03 to 0.12 µg L-1) and (0.03 to 0.15 µg L-1). These outcomes show satisfactory detectability of SPE-based methods, with slightly better performance using poly(MAA-co-EGDMA). On the other hand, poly(AA-co-EGDMA) was able to preconcentrate TCAs in the presence of humic acid (7.0 mg L-1) without interference. The precision of methods assessed as RSD (%) was very similar, ranging from 1.7% to 16.3% for poly(MAA-co-EGDMA) and 1.7% to 13.4% for poly(AA-co-EGDMA). SPE cartridges packed with the polymers showed high reusability (52 cycles of preconcentration and elution) without losing adsorption efficiency. The methods were applied to determine TCAs in tap, lake, and stream water samples and the accuracy was attested by addition and recovery tests (86.7-116.0%), with determined nortriptyline ranging from 0.48 to 0.52 µg L-1 in lake water samples.

Consumption, nicotine dependence and motivation for smoke cessation during early stages of COVID-19 pandemic in Brazil: A cross-sectional study.

INTRODUCTION: The COVID-19 pandemic may have changed smoking habits. For the smoking population, information regarding smoking habits and the pandemic could potentially aid COVID-19 prevention and control measures. Our study aimed to analyze the effects of the COVID-19 pandemic on tobacco consumption, nicotine dependence levels, and motivation for smoking cessation. We also collected information from smokers regarding their awareness of the consequences of tobacco use and the increased risks smokers have for severe complications from COVID-19. METHODS: In the survey for this observational cross-sectional study, 122 smokers responded to an online form. The participants provided general data about their smoking history, their smoking habits in the months of April and May 2020, and the effect of the pandemic on their smoking habits. They also completed a Fagerström test and were measured by the Wisconsin Smoking Withdrawal Scale. RESULTS: When compared to pre-pandemic levels, the majority of smokers reported increased tobacco consumption of between 1 and 10 cigarettes per day (37.7%). Their motivation to quit smoking (59.8%) and desire to smoke (53.2%) were unchanged by the pandemic. Most participants demonstrated an awareness of the increased risks smokers have for severe COVID-19-related complications (p<0.001). We identified the following correlations: cigarettes/day before pandemic and motivation for smoking cessation (r=0.19; p=0.030), cigarettes/day and nicotine dependence level (r=0.61; p<0.001), and load consumption and nicotine dependence level (r=0.69; p<0.001). No significant correlations were observed between load consumption and motivation to quit (r=0.13; p=0.120). CONCLUSIONS: Most smokers are well aware of their increased risks for severe COVID-19-related complications. In the early stages of the COVID-19 pandemic in Brazil, most smokers reported increased cigarette consumption. In addition, motivation to quit and desire to smoke were unchanged for the majority of smokers.

Methodological aspects of the assessment of dietary intake in the Brazilian National Survey on Child Nutrition (ENANI-2019): a population-based household survey.

This manuscript aims to describe the methodological, operational, and quality control aspects of the assessment of dietary intake in children under five years of age participating in the Brazilian National Survey on Child Nutrition (ENANI-2019), a household survey in a probability sample of Brazilian households. Two instruments were developed to assess child feeding practices - a structured, current status-type questionnaire and a 24-hour dietary recall (24HR), both installed in a mobile data collection device used by previously trained interviewers. A Photographic Manual for Quantification of Children's Dietary Intake was specifically developed for and used in the survey as a support aid to identify and quantify foods reported in the 24HR. During the fieldwork, continuous quality control of the records was performed. Data errors or incomplete data in the system were corrected, and the fieldwork team was systematically contacted and informed on their performance, with reiterated orientation on data collection. All children in the sample were evaluated with the two instruments, but data were obtained from the structured questionnaire on all children in the sample (n = 14,558) and 24HR on 14,541 children. ENANI-2019 developed innovative methods and materials based on the Brazilian and international literature to address knowledge gaps on under-five children's dietary intake. Unprecedented results will be produced, which will allow updating food and nutrition guidelines for children under five years of age in Brazil.

Aliskiren Attenuates the Inflammatory Response and Wound Healing Process in Diabetic Mice With Periodontal Disease.

The aim of this study was to characterize the role of local RAS (renin-angiotensin system) in the inflammatory response of normal (N) and diabetic (D) mice with periodontal disease (PD). Diabetes Mellitus (DM) was induced by peritoneal injection of streptozotocin in Balb/c mice. PD was induced by ligature around the first molar in both N and D, irrespective of whether they were treated with aliskiren (50 mg/kg, Alisk). Mandibles were harvested for histomorphometric analyses, and gingival tissue (GT) was collected to evaluate gene expression and extracellular matrix components (ECM). Immunohistochemical (IHC) analyses were used to localize RAS in GT. The production of C-reactive protein (CRP), IL-1ß, CXCL2, and CCL8 was evaluated by enzyme-linked immunosorbent assay (ELISA). Renin was found to exacerbate the inflammation and periodontal bone loss at 14 days after PD, and Alisk inhibited this process in GT of N and D. PD increased CRP, CXCL2, CCL8, and IL-1ß production in both animals. Alisk could inhibit CRP, CXCL2, and CCL8 primarily in D animals. However, only CCL8 was decreased in N animals after Alisk pretreatment. PD enhanced expression and production of AGT, ACE, AT1R, and AT2R in both N and D. AT1R expression was higher in D with PD, and AT2R expression was higher in N with PD. ACE2 and receptor Mas (MasR) expression and production was elevated in the control group of both animals. PD inhibited ACE2 in N but not in D. MasR expression was unaffected in both N and D with PD. Alisk reduced expression and production of all RAS components in GT of both animals, except for ACE2 in N. RAS staining was observed in all layers of epithelium, basal cell layer, and lamina propria and was higher in N with PD. Col1a1, Col1a2, Col3a1, and fibronectin (Fn1) were increased in both animals with PD. Alisk inhibited Col1a1 and Fn in both animals, Col1a2 was decreased only in D, while levels of Col3a1 remained unchanged in all animal groups. In conclusion, these data demonstrated the presence and functional role of local RAS in GT, exacerbating the inflammatory response, periodontal bone loss, and wound healing processes in both N and D animal groups. In addition, Alisk was able to significantly reduce gingival inflammation, excessive wound healing processes, and periodontal bone loss.

Skateholders, spaces and policy network in health governance in two health regions of Legal Amazon. / Atores, espaços e rede de políticas na governança em saúde em duas regiões de saúde da Amazônia Legal.

Governance is a concept with different hues in public policies. In this study, it is conceived as a policy network, with stakeholders who manage interests depending on available resources, mediated by rules and by their degree of influence. This paper analyzes the stakeholders, spaces of articulation, norms, and processes in health governance in two regions of the Legal Amazon and how managers shape their social network. This is a qualitative study with regional analysis plan, using as sources documents and interviews. An analysis matrix was formulated with adapted realms of conceptual models of governance and policy networks. Results point to differentiated policy networks. In the metropolitan region, stakeholders' diversity was more associated with state management and capital, given the articulation capacity and available resources. In the international border region, the policy network of municipal managers integrates stakeholders from diverse sectors in the face of regional specificity and articulation capacity. Regions, living territories, single out technical processes, leading stakeholders to seek partners and spaces beyond those established, to weave strategies closer to reality.

Governança é um conceito com distintas matizes no campo das políticas públicas e, neste estudo, é concebido enquanto rede de políticas, com atores que manejam interesses a depender dos recursos disponíveis, mediados por regras e por seu grau de influência. O artigo analisa os atores, os espaços de articulação, as normas e os processos na governança em saúde em duas regiões da Amazônia legal e também como os gestores modelam sua própria rede social. Trata-se de estudo qualitativo com plano de análise regional utilizando como fontes documentos e entrevistas. Formulou-se uma matriz de análise com dimensões adaptadas de modelos conceituais de governança e redes de políticas. Resultados apontam redes de políticas diferenciadas. Na região metropolitana, a diversidade de atores esteve mais associada à gestão estadual e capital, face à capacidade de articulação e recursos disponíveis. Na região de fronteira internacional, a rede dos gestores municipais integra atores, de setores diversificados face à especificidade territorial e capacidade de articulação. Regiões, territórios-vivos, singularizam processos técnicos, levando atores a buscarem parceiros e espaços para além dos instituídos, a fim de tecer estratégias mais correlatas à realidade.

Unidade básica amiga da saúde LGBT como executora de uma política transversal: um relato de experiência / Case detection and health education in a region endemic for leprosy: an experience report

O projeto da "Unidade Básica de Saúde Amiga da Saúde LGBT" tem como ação principal a mudança de práticas assistenciais à saúde para o público LGBTQIA+ na atenção básica. Essa estratégia tem a finalidade de desconstruir o sistema que reforça a transgressão de direitos à saúde direcionada a esta população. Trata-se de um estudo descritivo do tipo relato de experiência, com o objetivo de apresentar a experiência do projeto "UBS Amiga da Saúde LGBT " para execução da Política Nacional de Saúde Integral de gays, lésbicas, bissexuais, travestis e transexuais (PNSILGBT) na Atenção Primária à Saúde de Salvador no ano de 2022. A partir da vivência de uma enfermeira residente vinculada ao Programa de Residência Multiprofissional em Saúde da Família, inserida na Secretaria Municipal de Saúde de Salvador de junho a agosto de 2022. Pode-se notar que durante esse ano a implantação da estratégia foi iniciada em dez unidades, destas quatro conseguiram alcançar os critérios para certificação. Pesquisas enfatizam que a Educação permanente e educação em saúde com foco na população LGBTQIA+ é uma grande ferramenta para modificação das práticas de cuidado ainda pautadas na LGBTfobia. Portanto, conclui-se que a qualificação dos serviços de saúde, proposta pela UBS Amiga, capacita profissionais de saúde, o que corrobora o acesso e acolhimento de maneira qualificada do público LGBTQIA+ de acordo com suas especificidades nas unidades de saúde.

The main action of the "LGBT-friendly Basic Health Unit" project is to change health care practices for the LGBTQIA+ public in primary care. This strategy aims to deconstruct the system that reinforces the transgression of health rights for this population. This is a descriptive study of the experience report type, with the aim of presenting the experience of the "UBS Amiga da Saúde LGBT" project to implement the National Comprehensive Health Policy for Gays, Lesbians, Bisexuals, Transvestites and Transsexuals (PNSILGBT) in Primary Health Care in Salvador in 2022. From the experience of a resident nurse linked to the Multiprofessional Residency Program in Family Health, inserted in the Municipal Health Secretariat of Salvador from June to August 2022, it can be seen that during the year 2022 the implementation of the strategy was initiated in 10 units, of which 04 managed to reach the criteria for certification. Research emphasizes that continuing education and health education focused on the LGBTQIA+ population is a great tool for changing care practices that are still based on LGBTphobia. Therefore, it can be concluded that the qualification of health services, proposed by the UBS Amiga, trains health professionals, which corroborates the qualified access and reception of the LGBTQIA+ public according to their specificities in health units.

Effects of Neuroactive Drugs in the Discharge Patterns of Microsternarchus (Hypopomidae: Gymnotiformes) Electric Organ.

Considering the conserved nature of synaptic physiology among vertebrates, we tested the effects of three psychotropics (diazepam, doxapram, and nicotine) on Microsternarchus cf. bilineatus, measuring 10 parameters associated to the electric organ discharges rhythm and waveform before and after the administration of each drug and a control group. There were statistically significant differences (p < 0.005) among all the experimental groups, F (70, 22619.25) = 77.7, between the two experimental phases within their respective drug treatment, F (80, 24604.51) = 16.0, and among the six experimental hours within their respective phases and groups, F (320, 37124.15) = 4.1. We observed a common general trend of reduction in the electric organ's (EO) firing rate, regardless of the expected stimulant or depressor effect of the drugs on the central nervous system (CNS). The intensity of the response changed with the treatment. The observed changes in the fishes' behavior may be a result of the drugs' direct action on the CNS or a combination of this with systemic effects of each substance tested, also in the EO.

The Bunocephalus coracoideus Species Complex (Siluriformes, Aspredinidae). Signs of a Speciation Process through Chromosomal, Genetic and Ecological Diversity.

Bunocephalus is the most species-rich Aspredinidae genus, corresponding to a monophyletic clade with 13 valid species. However, many species have their classification put in question. Here, we analyzed individuals from four Amazonian populations of Bunocephalus coracoideus by cytogenetic and molecular procedures. The geographic distribution, genetic distances and karyotype data indicate that each population represents an Evolutionary Significant Unit (ESU). Cytogenetic markers showed distinct 2n and karyotype formulas, as well as different numbers and locations of the rDNA sites among ESUs. One of such populations (ESU-D) highlighted an extensive polymorphic condition, with several cytotypes probably due to chromosomal rearrangements and meiotic non-disjunctions. This resulted in several aneuploid karyotypes, which was also supported by the mapping of telomeric sequences. Phylograms based on Maximum Likelihood (ML) and Neighbor Joining (NJ) analyses grouped each ESU on particular highly supported clades, with the estimation of evolutionary divergence indicating values being higher than 3.8-12.3% among them. Our study reveals a huge degree of chromosomal and genetic diversity in B. coracoideus and highly points to the existence of four ESUs in allopatric and sympatric speciation processes. In fact, the high divergences found among the ESUs allowed us to delimitate lineages with taxonomic uncertainties in this nominal species.

First Cytogenetic Description of Microsternarchus bilineatus (Gymnotiformes: Hypopomidae) from Negro River (Brazilian Amazon).

Microsternarchus bilineatus is a neotropical electric fish species widely distributed in Amazonian ecosystems. This work reports the first karyotypic description of the species M. bilineatus, which presented 2n = 48 chromosomes, with a distinct karyotypic formula between the sexes: males with 21 metacentric (m)/submetacentric (sm) + 27 subtelocentric (st)/acrocentric (a) and fundamental number (FN) = 69 and females with 20 m/sm + 28 st/a and FN = 68. We found a probable recent sex system of XX/XY type. The nucleoli organizer regions (NORs) were multiple terminally located, and the heterochromatic blocks were mostly pericentromeric. The 18S rDNA markings confirmed NORs and their distinction between sexes, which suggested some differential role of this gene related to gender in this species. The 5S rDNA presented terminal markings on a single chromosome pair, with no distinction between sexes, and the telomeric probes have shown a uniform pattern in males and females.

Cryptic diversity between two Imparfinis species (Siluriformes, Heptapteridae) by cytogenetic analysis and DNA barcoding.

Five Imparfinis mirini and one Imparfinis minutus populations were studied using basic cytogenetic and molecular techniques. Cytogenetic analysis showed that I. mirini individuals presented the same diploid number 2n=58 (FN=116). However, they presented two distinct karyomorphs: karyomorph A (36m+18sm+4st) for the Mogi-Guaçu and Paranapanema basin populations, and karyomorph B (42m+12sm+4st) for the Tietê basin populations. I. minutus populations from the Paraíba do Sul basin presented a karyotype identical to karyomorph A of I. mirini. C-banding also presented distinct patterns, with a greater amount of heterochromatin, most of which was pericentromeric and interstitial for karyomorph A I. mirini and I. minutus. There was a minor amount of heterochromatin in karyomorph B, most of which was terminal and interstitial. Simple and interstitial nucleoli organizer regions were located in the biggest metacentric pair of the complement in all populations with GC-rich nature, and this location was confirmed by the fluorescent in situ hybridization technique with 18S ribosomal DNA with 5S rDNA synteny. In molecular analysis by DNA barcoding, two other populations from the Tietê basin were added. The phylogram showed that the populations were more related to the intrabasin. Cytogenetic resemblance among specimens from distinct basins may be the result of either recent convergence or ancestral feature retention not followed by mutations in mitochondrial DNA.

Food practices and their meanings in the daily routine of a university / Práticas alimentares e seus significados no cotidiano de uma universidade

ABSTRACT Objective This study aimed at knowing and analyzing sociocultural meanings of the daily dietary practices revealed by a university community, in the context of a wellness program to their community and its surroundings. Methods The research team ran 28 workshops with the participation of 34 university units and 558 subjects in total. All workshops were recorded and transcribed verbatim. Content analysis was performed with the identification of emerging themes and categories. Results From the analysis of this material four categories emerged. There is the desire caused by the pleasure of having meals in a group of people and consuming foods rich in fat and sugar, but with its consumption shrouded by guilt. Healthy foods were considered important but related to obligation and displeasure. The community also wants to consume healthy foods daily in the academic environment, however, pointed out barriers such as an increasing pace of work and lack of time. Conclusion It was possible to identify barriers and desires related to food practices in the daily life of the university. This study demonstrated that changing the eating behavior of an academic community is a major challenge for wellness programs, even for an institution that produces and disseminates scientific knowledge.

RESUMO Objetivo Este trabalho teve como objetivo conhecer e analisar os significados socioculturais das práticas alimentares cotidianas revelados pela comunidade de uma universidade brasileira no contexto de um programa de bem estar para sua comunidade e entornos. Métodos Foram realizadas 28 oficinas com a participação de 34 unidades universitárias e 558 pessoas. Todas as oficinas tiveram seu áudio gravado e transcrito. Foi realizada análise de conteúdo com a identificação de temas e categorias emergentes. Resultados A partir da análise do material transcrito, emergiram os significados em quatro categorias. Há o desejo pelo prazer de realizar as refeições em grupo e consumir alimentos ricos em gordura e açúcar, mas envolto por culpa. Alimentos saudáveis foram considerados importantes, mas seu consumo foi relacionado à obrigação e desprazer. Contudo, a comunidade deseja consumi-los diariamente no ambiente acadêmico, mas aponta barreiras como o aumento do ritmo de trabalho e falta de tempo. Conclusão Foi possível identificar barreiras e desejos relacionados às práticas alimentares no cotidiano da universidade. Este estudo mostrou que transformar o comportamento alimentar de uma comunidade acadêmica é um grande desafio para os programas de bem-estar, mesmo para instituições que produzem e disseminam conhecimentos científicos.

Determinants of food and nutrition actions in primary healthcare clinics in the State of São Paulo, Brazil / Determinantes de las acciones de alimentación y nutrición en las clínicas de atención primaria en el estado de São Paulo, Brasil

The objective of the study was to test the link between the preparation of professionals and the operational conditions of food and nutrition actions in primary healthcare in the state of São Paulo, Brazil. This cross-sectional study involved 220 primary healthcare clinics in 65 municipalities of the state. Of the 1873 participating healthcare professionals, 71.8% reported having provided guidance on food and nutrition to different groups, ranging from 56% for pregnant women to 17% for families. Only 19% of the primary healthcare clinics employed nutritionists. Primary healthcare clinics with fewer than two partnerships with other institutions reported 28% and 41% fewer of food and nutrition actions for adults and for families, respectively. Among the variables applied to evaluate professional preparation and operational conditions, work guidance and community partnerships were important for food and nutrition actions, which remains incipient in primary healthcare.

De los 1873 profesionales de salud participantes, 71,8% relataron haber realizado acciones de alimentación y nutrición, variando de 56% para gestantes a 17% para las familias entre las unidades de salud. Apenas 19% de las unidades de salud contaban con nutricionistas. En unidades de salud con menos de dos convenios hubo prevalencia de 28% y 41% menos de oferta de acciones de alimentación y nutrición para adultos y familias, respectivamente. Entre las variables utilizadas para evaluar la preparación profesional y las condiciones operacionales, la orientación para el trabajo y los convenios en la comunidad fueron determinantes para la oferta de acciones de alimentación y nutrición, aun incipientes en la Atención Primaria a la Salud.

Atuação do enfermeiro no cuidado ao paciente com câncer de pênis / Nursing performance in the care of patients with penile cancer

Objetivo: conhecer a atuação do enfermeiro no cuidado ao paciente com câncer de pênis. Metodologia: estudo descritivo, abordagem qualitativa, realizado com cinco enfermeiras, por meio de entrevista semiestruturada e análise de prontuários, em um hospital de referência para o câncer em Belém do Pará. Utilizou-se o método de análise de conteúdo de Bardin. A pesquisa foi autorizada pelo Comitê de Ética em Pesquisa da Faculdade Metropolitana da Amazônia, com o número de parecer 2.574.409. Resultados: o cuidado de enfermagem se dá de forma sistematizada, respeitando a individualidade, mesmo não existindo um protocolo específico. Da análise de conteúdo surgiram quatro categorias: protocolo existente para o cuidado ao paciente com câncer de pênis, aplicação da Sistematização da Assistência de Enfermagem, identificação dos Diagnósticos de Enfermagem, aplicação das Intervenções de Enfermagem. Conclusão: sugere-se a elaboração e adoção de Procedimentos Operacionais Padrão para ser utilizado juntamente com a Sistematização da Assistência de Enfermagem, pois, não apenas uniformizam as ações dos profissionais, mas também contribuem com assistência de qualidade e a segurança do paciente.

Objective: to know the role of the nurse in the care of patients with penile cancer. Methodology: this is a descriptive study with a qualitative approach, performed with five nurses, through a semi-structured interview and analysis of medical records at a referral hospital for cancer in Belém, Pará. The Bardin content analysis method was used. The research was authorized by the Research Ethics Committee of the Metropolitan University of Amazonia, with the number of opinion 2,574,409. Results: Nursing care occurs in a systematized manner, respecting the individuality, even if there is no specific protocol. From the content analysis, four categories emerged: the existing protocol for the care of the patient with penile cancer, application of Nursing Care Systematization, identification of Nursing Diagnoses and application of Nursing Interventions. Conclusion: It is suggested that Standard Operational Procedures be developed and adopted to be used in conjunction with the Nursing Care Systematization, on this account they not only standardize the actions of the professionals, but also contribute with quality care and patient safety.

Cytogenetics of two Farlowella species (Loricariidae: Loricariinae): implications on the taxonomic status of the species

Farlowella is one of the most diverse genera of the Loricariinae, restricted to South America rivers. The taxonomic and phylogenetic relationships among its species are contentious and, while genetic studies would contribute to the understanding of their relationships, the only available datum refer to the karyotype description of only one species. In the present study two Amazonian species, Farlowella cf. amazonum and F. schreitmuelleri, were analyzed using conventional and molecular cytogenetic procedures. Both species had diploid chromosome number 58, but different fundamental numbers (NF) 116 and 112, respectively, indicative of chromosomal rearrangements. C-banding is almost poor, especially in F. cf. amazonum, and occurs predominantly in the centromeric and in some telomeric regions, although genome of F. schreitmuelleri possessed a much larger heterochromatin amount then those of F. cf. amazonum. The chromosomes bearing the NOR sites were likely the same for both species, corresponding to the 1st metacentric pair in F. cf. amazonum and to the 28th acrocentric in F. schreitmuelleri. The location of the 5S rDNA was species-specific marker. This study expanded the available cytogenetic data for Farlowella species and pointed the remarkable karyotype diversity among species/populations, indicating a possible species complex within genus.(AU)

Farlowella é um dos gêneros mais diversos de Loricariinae, restrito aos rios da América do Sul. As relações taxonômicas e filogenéticas entre suas espécies são contenciosas e, enquanto os estudos genéticos contribuem para a compreensão dessas relações, o único dado disponível refere-se à descrição cariotípica de apenas uma espécie. No presente estudo, foram analizadas duas espécies amazônicas Farlowella cf. amazonum e F. schreitmuelleri, empregando procedimentos citogenéticos convencionais e moleculares. Ambas as espécies apresentaram número diploide igual a 58 cromossomos, mas com números fundamentais diferentes (NF) de 116 e 112, respectivamente, indicando rearranjos cromossômicos. Bandas C são poucas, especialmente em F. cf. amazonum, e ocorre predominantemente nas regiões centroméricas e em algumas regiões teloméricas, embora F. schreitmuelleri apresenta uma quantidade de heterocromatina muito maior que F. cf. amazonum. Os cromossomos carreadores dos sítios da NOR foram provavelmente os mesmos para ambas as espécies, correspondendo ao primeiro par metacêntrico em F. cf. amazonum e ao 28º acrocêntrico em F. schreitmuelleri. A localização do DNAr 5S foi espécie-específico. Este estudo expandiu os dados citogenéticos disponíveis para espécies de Farlowella e apontou uma remarcável diversidade cromossômica entre espécies/populações, indicando um possível complexo de espécies neste gênero.(AU)

Atores, espaços e rede de políticas na governança em saúde em duas regiões de saúde da Amazônia Legal / Skateholders, spaces and policy network in health governance in two health regions of Legal Amazon

Resumo Governança é um conceito com distintas matizes no campo das políticas públicas e, neste estudo, é concebido enquanto rede de políticas, com atores que manejam interesses a depender dos recursos disponíveis, mediados por regras e por seu grau de influência. O artigo analisa os atores, os espaços de articulação, as normas e os processos na governança em saúde em duas regiões da Amazônia legal e também como os gestores modelam sua própria rede social. Trata-se de estudo qualitativo com plano de análise regional utilizando como fontes documentos e entrevistas. Formulou-se uma matriz de análise com dimensões adaptadas de modelos conceituais de governança e redes de políticas. Resultados apontam redes de políticas diferenciadas. Na região metropolitana, a diversidade de atores esteve mais associada à gestão estadual e capital, face à capacidade de articulação e recursos disponíveis. Na região de fronteira internacional, a rede dos gestores municipais integra atores, de setores diversificados face à especificidade territorial e capacidade de articulação. Regiões, territórios-vivos, singularizam processos técnicos, levando atores a buscarem parceiros e espaços para além dos instituídos, a fim de tecer estratégias mais correlatas à realidade.

Abstract Governance is a concept with different hues in public policies. In this study, it is conceived as a policy network, with stakeholders who manage interests depending on available resources, mediated by rules and by their degree of influence. This paper analyzes the stakeholders, spaces of articulation, norms, and processes in health governance in two regions of the Legal Amazon and how managers shape their social network. This is a qualitative study with regional analysis plan, using as sources documents and interviews. An analysis matrix was formulated with adapted realms of conceptual models of governance and policy networks. Results point to differentiated policy networks. In the metropolitan region, stakeholders' diversity was more associated with state management and capital, given the articulation capacity and available resources. In the international border region, the policy network of municipal managers integrates stakeholders from diverse sectors in the face of regional specificity and articulation capacity. Regions, living territories, single out technical processes, leading stakeholders to seek partners and spaces beyond those established, to weave strategies closer to reality.
