Abstract Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21st (IG21). Methods: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals. Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis. Selected growth phenotypes: small-for-gestational-age (SGA) defined as being < 3rd (SGA3) or 10th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97th percentile of BW. Stunting as being < 3rd percentile of the length and wasting as being < 3rd percentile of BMI. Single and multiple log-binomial regression models were fitted to estimate the relative risks of CNMM, comparing them to IG21. Results: 4,072 infants were included. The adjusted relative risks of CNMM associated with selected growth phenotypes were (BNRN/IG21): 1.45 (0.92–2.31)/1.60 (1.27–2.02) for SGA; 0.90 (0.55–1.47)/1.05 (0.55–1.99) for LGA; 1.65 (1.08–2.51)/1.58 (1.28–1.96) for stunting; and 1.48 (1.02–2.17) for wasting. Agreement between the two references was variable. The growth phenotypes had good specificity (>95%) and positive predictive value (70-90%), with poor sensitivity and low negative predictive value. Conclusion: The BNRN phenotypes at birth differed markedly from the IG21 standard and showed poor accuracy in predicting adverse neonatal outcomes.

Abstract Canga is an environment of great natural and economic value because it harbours a considerable number of endemic species on a substrate that is rich in iron ore. In the Amazon, this open vegetation type grows on top of isolated outcrops in a dense forest matrix found in the Carajás region, in southeastern Pará. Of these outcrops, the Parque Nacional dos Campos Ferruginosos (PNCF) is the only area of Amazonian canga with a strict protection status. Therefore, industrial activity in the region needs to implement mitigation actions to ensure species and habitat conservation. The objective of this study is to complement and review the floristic list of this recently created protected area, enabling us to compare the floristic similarity between it and other 14 Amazonian canga outcrops found outside the conservation units of full protection in the region. This data provides a basis to understand the floristic and phylogenetic complementarity of those patches to support conservation action. For this, six field trips were carried out in the Serra da Bocaina and two in the Serra do Tarzan, respectively, in order to increase the sampling efforts in PNCF and to obtain a more comprehensive plant list. Floristic composition was investigated using multivariate analyses (non-metric multidimensional scaling and unweighted pair group method with arithmetic mean) and phylogenetic structure across studied areas. We added 159 species to the floristic list of the PNCF and the results of the analyses showed that all 16 areas (n.b. PNCF comprises two of these sites) have an overall floristic similarity of 42%, with the least similar areas at 35% and the most similar at 50%. The different micro-habitats found in each study site highlight the high beta diversity of the Amazonian canga sites, making each area unique. Therefore, even if the Parque Nacional dos Campos Ferruginosos does not harbour all the species found in the other Amazonian canga sites, it is strategic for the conservation of the vegetation on ferruginous outcrops in the Amazon, protecting its biodiversity, different habitats, and associated ecosystem services.
Resumo Canga é um ambiente de grande valor natural e econômico por abrigar um número considerável de espécies endêmicas sobre substrato rico em minério de ferro. Na Amazônia, esse tipo de vegetação aberta cresce sobre afloramentos isolados em uma matriz de floresta densa encontrada na região de Carajás, no sudeste do Pará. Dentre esses afloramentos, o Parque Nacional dos Campos Ferruginosos (PNCF) é a única área de canga Amazônica que apresenta o status de proteção integral permanente. Dessa forma, a atividade industrial presente na região necessita implementar ações de mitigação para assegurar a conservação de espécies e habitats relacionados às cangas. O objetivo deste estudo é complementar e revisar a lista florística dessa área protegida, recentemente criada, permitindo comparar a sua similaridade florística com outros 14 afloramentos de cangas Amazônicas localizados fora de unidades de conservação de proteção integral encontradas na região. Tais dados fornecem subsídio para entender a complementaridade florística e filogenética desses fragmentos para apoiar ações de conservação. Para isso, foram realizadas seis viagens de coleta à Serra da Bocaina e à Serra do Tarzan, respectivamente, para aumentar o esforço amostral no PNCF e obter uma lista de plantas mais abrangente. A composição florística foi investigada por meio de análises multivariadas (non-metric multidimensional scaling and unweighted pair group method with arithmetic mean) e estrutura filogenética nas áreas estudadas. Nós adicionamos 159 espécies na lista florística do PNCF e os resultados das análises demonstraram que todas as 16 áreas (n.b. o PNCF compreende duas dessas áreas) têm uma similaridade florística total de 42%, com áreas menos similares de 35% e as mais similares de 50%. Os micro-habitats encontrados em cada área de estudo evidenciam a alta diversidade beta das áreas de cangas Amazônicas, o que as tornam únicas. Portanto, ainda que o Parque Nacional dos Campos Ferruginosos não abrigue todas as espécies encontradas em outras áreas de cangas Amazônicas, ele é estratégico para a conservação dos afloramentos ferruginosos na Amazônia, protegendo a sua biodiversidade, os diferentes habitats e os serviços ecossistêmicos associados.

Abstract Objective: To evaluate the performance of Gram, glucose and leukocytes in amniotic fluid for the diagnosis of fetal and maternal inflammatory response in patients with preterm delivery. Method: A diagnostic performance test study was carried out. Sixty-three patients with preterm labor were included who underwent amniocentesis due to suspected intra-amniotic infection. Histopathology of the placenta was studied and compared with the Gram result, glucose and leukocyte count in amniotic fluid, and their relationship with the maternal and fetal inflammatory response. Sensitivity, specificity, likelihood ratios, predictive values, and kappa were evaluated. Results: The tests with the best performance were overall glucose < 15 mg/dL and leukocytes > 50/mm3 in amniotic fluid for the diagnosis of the fetal inflammatory response, with a specificity of 94.3% (95% confidence interval [95% CI]: 84.6-98.1%), likelihood positive ratio 8.83 (95% CI: 2.5-31.2) and kappa of 0.48 (95% CI: 0.15-0.82). A new cut-off point for leukocyte count in amniotic fluid to diagnose fetal inflammatory response was proposed. Conclusions: The combination of amniotic fluid leukocyte count and amniotic fluid glucose values improves performance for the diagnosis of inflammatory response compared with placental histopathology, providing useful information for newborns’ approach.
Resumen Objetivo: Evaluar el rendimiento del Gram, la glucosa y los leucocitos en líquido amniótico para el diagnóstico de respuesta inflamatoria fetal y materna en pacientes con parto pretérmino. Método: Estudio de rendimiento de pruebas diagnósticas. Se incluyeron 63 pacientes a quienes se les realizó amniocentesis por sospecha de infección intraamniótica. Se estudió la placenta y se comparó con el Gram, la glucosa y el recuento de leucocitos en líquido amniótico para ver su relación con la respuesta inflamatoria. Se evaluaron la sensibilidad, la especificidad, las razones de verosimilitud (LR, likelihood ratio), los valores predictivos y el valor de kappa. Resultados: Las pruebas con mejor rendimiento fueron en conjunto la glucosa < 15 mg/dl y los leucocitos > 50/mm3 en líquido amniótico, con una especificidad del 94,3% (intervalo de confianza del 95% [IC95%]: 84,6-98,1), LR + 8,83 (IC95%: 2,5-31,2) y kappa de 0,48 (IC95%: 0,15-0,82). También se consideró la propuesta de un nuevo punto de corte para el recuento de leucocitos en líquido amniótico en la respuesta inflamatoria fetal. Conclusiones: La combinación del recuento de leucocitos en líquido amniótico y los valores de glucosa mejora el rendimiento para el diagnóstico de respuesta inflamatoria fetal en comparación con la histopatología de la placenta, lo que proporciona información útil para el enfoque de los recién nacidos.

Abstract Background: Ocular trauma is one of the leading causes of decreased visual acuity and monocular blindness in the pediatric population. Since its occurrence is potentially preventable, it is essential to understand its demographic characteristics and risk factors to alert and implement prevention and health promotion programs. Methods: We conducted a retrospective study in which we reviewed 187 clinical records of patients ≤ 15 years old with the diagnosis of severe ocular trauma admitted in 2017 to the Hospital Civil de Guadalajara. We analyzed demographic variables, circumstances of the event, type of treatment, and the evolution of visual acuity and complications. Results: In total, 187 patients and 188 eyes were included; the average age was 6.99 ± 4.1 years. Children of 2 to 5 years of age (41%) were the most affected, and a higher occurrence was observed in males (73%). Open ocular trauma was the most common type of injury (72.7%) caused by sharp objects (45.4%). Most injuries occurred at home (78.1%), without adult supervision (48.1%), and during leisure time (74.9%). Most events were accidental (80.4%), although 12.3% were direct aggression. Surgery was required in 179 patients, in whom corneal injury repair (43.2%) was the most commonly used procedure. Final visual acuity was quantified in 132 eyes, and visual acuity < 20/200 was found in 18.1%. Loss of 4.2% of the eyeballs was recorded. Conclusions: The highest proportion of cases was identified in male patients ≤5 years old, unsupervised by an adult. Many eye injuries are preventable, so it is necessary to implement socio-educational programs in alliance with pediatric organizations that alert the severity of the problem and promote safe environments.
Resumen Introducción: El trauma ocular es una de las principales causas de disminución de la agudeza visual y de ceguera monocular en la población pediátrica. Su ocurrencia es potencialmente prevenible, por lo que es importante entender sus características demográficas y riesgos para alertar e implementar programas enfocados hacia la prevención y la promoción de la salud. Métodos: Estudio retrospectivo en el que se analizaron 187 expedientes de pacientes ≤ 15 años con diagnóstico de trauma ocular grave ingresados en 2017 al Hospital Civil de Guadalajara. Se analizaron variables demográficas, circunstancias del evento y tipo de tratamiento, así como la evolución de la agudeza visual y las complicaciones. Resultados: Se incluyeron 187 pacientes y 188 ojos; el promedio de edad en el momento del trauma fue de 6.99 ± 4.1 años. Los niños de 2-5 años (41%) fueron los más afectados y se observó una mayor ocurrencia en el sexo masculino (73%). El trauma ocular abierto fue el tipo de lesión más común (72.7%), causado por objetos punzantes (45.4%). La mayoría de las lesiones ocurrieron en casa (78.1%), sin supervisión de un adulto (48.1%) y durante el tiempo libre (74.9%). La mayoría de los sucesos fueron accidentales (80.4%), aunque el 12.3% fue por agresiones directas. Se requirió cirugía en 179 pacientes, en quienes la reparación de lesión corneal (43.2%) fue el procedimiento más utilizado. La agudeza visual final se cuantificó en 132 ojos y se encontró < 20/200 en el 18.1%. Se registró la pérdida del 4.2% de los globos oculares. Conclusiones: La proporción más alta de casos se identificó en pacientes de sexo masculino ≤ 5 años, que se encontraban sin supervisión. Una gran proporción de las lesiones oculares son prevenibles, por lo que es necesario implementar programas educativos sociales en coordinación con organizaciones pediátricas que alerten de la gravedad del problema y promuevan entornos seguros.

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.

ABSTRACT Objective: The aim of the present study was to examine the influence of body composition and insulin resistance on the magnitude of postprandial lipemia in patients with Turner's syndrome receiving oral versus transdermal estrogen replacement. Subjects and methods: Twenty-five patients with Turner's syndrome receiving oral or transdermal estrogen replacement were evaluated for body mass index, waist-to-hip and waist-to-height ratios, fasting glycemia, insulin, body composition (dual-energy X-ray absorptiometry), and postprandial lipid metabolism. For statistical analysis, we used parametric tests to compare numeric variables between the two subgroups. Results: We observed no difference in postprandial triglyceride levels between patients receiving oral versus transdermal hormone replacement therapy. The postprandial triglycerides increment correlated positively with the percentage of total fat mass (p=0.02) and android fat mass (p=0.02) in the transdermal group. In the oral estrogen group, a positive correlation was observed between the increment in postprandial triglycerides and waist-to-hip (p=0.15) and waist-to-height (p=0.009) ratios. No association was observed between the estrogen replacement route and insulin resistance evaluated by the homeostatic model assessment–insulin resistance (HOMA-IR) index (p=0.19 and p=0.65 for the oral and transdermal groups, respectively). Conclusion: We concluded that body composition and anthropometric characteristics possibly affect the extent of postprandial lipemia independently from the route of estrogen replacement.

Resumen La composición química de la cáscara de cacao Theobroma cacao L. permite catalogarla como un material de difícil degradación debido a su alto contenido de lignina y celulosa, en donde este material lignocelulósico se puede utilizar en una amplia variedad de procesos industriales; sin embargo, esta cáscara generalmente es desechada dentro de los mismos cultivos y genera problemáticas como la proliferación de microorganismos patógenos. Por otra parte, el almidón es una sustancia granulada presente en diferentes matrices vegetales la cual puede usarse desde la industria alimentaria para otorgar características sensoriales y organolépticas, hasta la manufactura de papel y materiales biodegradables. El objetivo de esta investigación fue extraer el almidón presente en la cáscara de cacao. La biomasa vegetal (cáscara de cacao) se caracterizó teniendo en cuenta parámetros como pH, porcentaje de humedad, grasa y fibra, entre otros; seguido de la extracción del almidón por vía húmeda. Los resultados obtenidos a la cáscara de cacao reportaron un valor de pH 5,46±0,006, acidez titulable 0,11±0,038, humedad 84,35±0,02, cenizas 8,21±0,006, grasa 0,80±0,02, fibra 6,80±0,01 y la extracción de almidón reportó 12,04±0,03. Para concluir, con el uso del residuo del cacao pueden generarse alternativas de aprovechamiento, produciendo nuevos biomateriales a partir de este subproducto, siendo esta una alternativa de bioprospección agroindustrial.
Abstract The chemical composition of the cocoa husk Theobroma cacao L. allows to catalog it as material of difficult degradation, due its high lignin and cellulose content, where the lignocellulosic material can be used in a wide variety of industrial processes; however, this husk is generally discarded within the crops themselves and this husk generate problems such as the proliferation of pathogenic microorganisms. On the other hand, the starch it’s a granulated substance that it’s presented in different plant matrices, which can be used from the alimentary industry for grant sensorial and organoleptic characteristics, to the manufacture of paper and biodegradable materials. The objective of this research was extracting the starch present in the cocoa husk, thus determinate the possible uses of exploitation of starch, as an alternative of bioprospection. The vegetal material (cocoa husk) was characterized taking into account parameters as pH, moisture percentage, fat and fiber, among others; followed by starch extraction by wet method. The obtained results to the cocoa husk reported a value of pH 5.46 ±0.0057, titratable acidity 0.11±0.038, moisture 84.35±0.017, ash 8.21±0.0057, fat 0.80±0.015, fiber 6.80 ±0.01and the extraction of starch reports 12.04±0.025. To conclude, with the use of the cocoa waste exploitation alternatives can be generate, producing new biomaterials starting of this sub product, being this an alternative of agroindustrial bioprospection.
Resumo A composição química da casca de cacau Theobroma cacao L. permite que ela seja classificada como um material de difícil degradação devido ao seu alto teor de lignina e celulose, onde esse material lignocelulósico pode ser usado em uma ampla variedade de processos industriais; no entanto, essa casca é geralmente descartada nas próprias culturas e gera problemas como a proliferação de microorganismos patogênicos. Por outro lado, o amido é uma substância granulada presente em diferentes matrizes vegetais que podem ser utilizadas na indústria de alimentícia para fornecer características sensoriais e organolépticas, para a fabricação de papel e materiais biodegradáveis. O objetivo desta investigação foi extrair o amido presente na casca do cacau.

RESUMO: A obesidade pode estar associada ao aparecimento de tumores mamários em mulheres. Em animais de companhia, esse dado ainda é escasso, principalmente associando a clínica da paciente aos achados laboratoriais e histológicos. Este estudo objetivou avaliar os aspectos clínicos e laboratoriais de cadelas com neoplasia mamária, investigando se estão relacionadas à obesidade. Foram estudados quatro grupos de cadelas castradas ou não castradas, divididas em (G1) cadelas sem tumor de mama e Escore de Condição Corporal normal (BCS), (G2) cadelas sem tumor de mama e obesa, (G3) cadelas com tumor de mama e ECC normal e (G4) cadelas com tumor de mama e obesa. Foram avaliados o Escore de Condição Corporal (ECC), Índice de Massa Corporal Canina (IMC), hemograma, glicose, colesterol total, triglicerídeos e exames citopatológicos e histopatológicos. Os animais de raça mista foram os mais prevalentes neste estudo (67,5%). Houve uma limitação quanto ao uso do IMC relacionado à proporcionalidade corporal. Considerando os 28 tumores avaliados, o carcinoma em tumor misto foi o tipo histológico maligno mais prevalente, enquanto o adenomioepitelioma foi o tipo histológico benigno mais prevalente. Foi possível concluir que a obesidade não esteve relacionada a alterações clínicas e laboratoriais nas cadelas acometidas por neoplasias mamárias. Além disso, não foi observada relação entre BCS e CBMI com o tipo histológico ou malignidade das neoplasias mamárias, uma vez que os tipos histológicos malignos foram os tumores mais prevalentes no grupo escore ideal e no grupo com sobrepeso e obesidade.
ABSTRACT: Obesity may be associated with the onset of mammary tumors in women. In companion animals, these data are still scarce, mainly associating the clinic of the patient with laboratory and histological findings. This study aimed to evaluate the clinical and laboratory aspects of female dogs with mammary neoplasia, investigating whether they are related to obesity. Four groups of spayed or non-spayed female dogs were studied, divided into (G1) female dogs without mammary tumor and normal body condition score (BCS), (G2) female dogs without mammary tumor and obese, (G3) female dogs with mammary tumor and normal BCS and (G4) female dogs with mammary tumor and obese. BCS, canine body mass index (CBMI), blood count, glucose, total cholesterol, triglycerides and cytopathological and histopathological examinations were evaluated. Mixed-breed animals were the most prevalent in this study (67.5%). There was a limitation regarding the use of CBMI related to body proportionality. Considering the 28 tumors evaluated, carcinoma in mixed tumor was the most prevalent malignant histological type, while adenomyoepithelioma was the most prevalent benign histological type. It was possible to conclude that obesity was not related to clinical and laboratory changes in the female dogs affected with mammary neoplasias. In addition, no relationship was noted between BCS and CBMI with the histological type or malignancy of mammary neoplasia, since the malignant histological types were the most prevalent tumors in both the ideal score group and the overweight to obese group.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
