Abstract Background: obesity can influence vitamin D levels, which in turn might be associated with cardiometabolic risk factors. Objectives: this study assessed the association between 25-hydroxyvitamin D [25(OH)D] levels and cardiometabolic risk factors in adolescents with overweight living in a region of northeastern Brazil. Material and methods: a cross-sectional study was carried out by non-probabilistic sampling in adolescents diagnosed with overweight or obesity. The subjects were divided according to their 25(OH) D status into two groups: sufficient vitamin D and hypovitaminosis D. Biodemographic, lifestyle, cardiometabolic, and biochemical factors were evaluated. A logistic regression model was applied to determine the predictors of hypovitaminosis D. Results: we found a high frequency of hypovitaminosis D (45.6 %) in adolescents. Weekly sun exposure was negatively associated with hypovitaminosis D (OR = 0.96; 95 % CI: 0.92-0.99), while significant positive associations were observed between hypovitaminosis D and blood pressure above the 95th percentile (OR = 4.00; 95 % CI: 1.19-13.37), body weight (OR = 1.04; 95 % CI: 1.01-1.07), and fasting insulin (OR = 1.13; 95 % CI: 1.05-1.22). Conclusion: hypovitaminosis D showed a high prevalence in adolescents with overweight living in a sunny region of northeastern Brazil, and cardiometabolic risk factors such as systemic arterial hypertension, high body weight, and hyperinsulinemia are predictors of hypovitaminosis D.
Resumen Introducción: la obesidad puede influir en los niveles de vitamina D, lo que a su vez podría estar asociado con factores de riesgo cardiometabólico. Objetivos: este estudio evaluó la asociación entre los niveles de 25-hidroxivitamina D [25(OH)D] y los factores de riesgo cardiometabólico en adolescentes con sobrepeso que viven en una región del noreste de Brasil. Material y métodos: se realizó un estudio transversal mediante muestreo no probabilístico con adolescentes diagnosticados de sobrepeso u obesidad. Los sujetos se dividieron según su estado de 25(OH) D en dos grupos: suficiente vitamina D e hipovitaminosis D. Se evaluaron factores biodemográficos, de estilo de vida, cardiometabólicos y bioquímicos. Se aplicó un modelo de regresión logística para determinar los predictores de la hipovitaminosis D. Resultados: encontramos una alta frecuencia de hipovitaminosis D (45,6 %) en los adolescentes. La exposición semanal al sol se asoció negativamente a la hipovitaminosis D (OR = 0,96; IC 95 %: 0,92-0,99), mientras que se observaron asociaciones positivas significativas entre hipovitaminosis D y presión arterial por encima del percentil 95 (OR = 4,00; IC 95 %: 1,19-13,37), peso corporal (OR = 1,04; IC del 95 %: 1,01-1,07) e insulina en ayunas (OR = 1,13; IC del 95 %: 1,05-1,22). Conclusión: la hipovitaminosis D mostró una alta prevalencia entre los adolescentes con sobrepeso que viven en una región soleada del noreste de Brasil, y los factores de riesgo cardiometabólico, como hipertensión arterial sistémica, peso corporal elevado e hiperinsulinemia, son predictores de hipovitaminosis D.

Abstract Objectives This analysis describes the protocol of a study with a case-cohort to design to prospectively evaluate the incidence of subclinical atherosclerosis and Cardiovascular Disease (CVD) in Chronic Inflammatory Disease (CID) participants compared to non-diseased ones. Methods A high-risk group for CID was defined based on data collected in all visits on self-reported medical diagnosis, use of medicines, and levels of high-sensitivity C-Reactive Protein >10 mg/L. The comparison group is the Aleatory Cohort Sample (ACS): a group with 10% of participants selected at baseline who represent the entire cohort. In both groups, specific biomarkers for DIC, markers of subclinical atherosclerosis, and CVD morbimortality will be tested using weighted Cox. Results The high-risk group (n = 2,949; aged 53.6 ± 9.2; 65.5% women) and the ACS (n=1543; 52.2±8.8; 54.1% women) were identified. Beyond being older and mostly women, participants in the high-risk group present low average income (29.1% vs. 24.8%, p < 0.0001), higher BMI (Kg/m2) (28.1 vs. 26.9, p < 0.0001), higher waist circumference (cm) (93.3 vs. 91, p < 0.0001), higher frequencies of hypertension (40.2% vs. 34.5%, p < 0.0001), diabetes (20.7% vs. 17%, p = 0.003) depression (5.8% vs. 3.9%, p = 0.007) and higher levels of GlycA a new inflammatory marker (p < 0.0001) compared to the ACS. Conclusions The high-risk group selected mostly women, older, lower-income/education, higher BMI, waist circumference, and of hypertension, diabetes, depression, and higher levels of GlycA when compared to the ACS. The strategy chosen to define the high-risk group seems adequate given that multiple sociodemographic and clinical characteristics are compatible with CID.

Abstract The environmental and health risks associated with the application of synthetic chemical inputs in agriculture increased the demand for technologies that allow higher performance and quality of vegetable crops by implementing synergistic materials with the principles of sustainability. In this work, the seed coating with the biomass of Dunaliella salina incorporated in a bioplastic film of Manihot esculenta (cassava) was evaluated as an initial growth and secondary compounds stimulator of Coriandrum sativum (coriander) plants. The obtained results demonstrated that the coating stimulated an increase in the germination percentage (28.75%) and also in concentration of bioactive compounds, such as the six-fold increment of caffeic acid (13.33 mg 100 g-1). The carbohydrates, lipids, and proteins present in the microalgae biomass seem to be responsible for these increments once they are known for providing energy to the seedling development and coordinating the secondary metabolites synthesis. As conclusion, we consider the coating with biomass of D. salina an alternative for crop improvement that contributes to the development of sustainable agricultural practices.

Abstract Objective: Determinate instant and after 1-month non-dipper effect in hypertense patients after renal transplant by 24-hour ambulatory blood pressure monitoring in Hospital General de Zona No. 50, San Luis Potosí, Mexico. Method: Descriptive, longitudinal and prospective cohort study of a non-probability convenience sampling in post-transplant patients with hypertension. We collected data from MAPA and includes age, sex, cardiovascular risk factors in variables. Use of central tendency and dispersion measures for descriptive analysis and t Student for inferential analysis. Results: 19 patients were included, 11 male (57.9%) and 8 females (42.1%), with age range 20 to 49 years (median of 30.2 years ± 7.7). Where the non-dipper effect in the first take was 89.5% and in the second take 84.2%. Conclusions: There is a high frequency of the non-dipper pattern in patients at one month of kidney transplant, the persistence of this hypertension may be, among others, by the use of immunosuppressants. A new category for non-dipper classification is described.
Resumen Objetivo: Determinar el efecto non-dipper inmediato y posterior a 1 mes en pacientes adultos hipertensos postrasplante renal con monitoreo continuo de la presión arterial de 24 horas, en el Hospital General de Zona No. 50 de San Luis Potosí, México. Método: Estudio de tipo cohorte, longitudinal, prospectivo, con muestreo no probabilístico por conveniencia de casos consecutivos en pacientes receptores de trasplante renal con hipertensión arterial. Se recogieron los siguientes datos: edad, sexo, factores de riesgo cardiovascular, uso de antihipertensivos o inmunosupresores, y monitoreo ambulatorio de la presión arterial de 24 horas. Se aplicaron medidas de tendencia central y de dispersión para análisis descriptivo, y prueba t de Student para análisis inferencial. Resultados: Se incluyeron 11 hombres (57.9%) y 8 mujeres (42.1%), con una edad de 20 a 49 años (media 30.2 ± 7.7), en los que el efecto non-dipper inmediato fue del 89.5% y posterior a 1 mes fue del 84.2%. Conclusiones: Existe una alta frecuencia del patrón non-dipper en pacientes a 1 mes del trasplante renal. La persistencia de la hipertensión puede ser, entre otras causas, por el uso de inmunosupresores. Se describe una nueva categoría para la clasificación non-dipper.

The assignment of absolute configuration (AC) is a crucial step in the structural characterization of natural products, especially for those subjected to biological assays. Methods such as X-ray crystallography, stereocontrolled organic synthesis, nuclear magnetic resonance (NMR), and chiroptical spectroscopies are commonly used to determine the AC of chiral natural compounds. Even with these well-established techniques, however, unambiguous stereochemical assignments of natural products remain a challenge, resulting in an increasing number of structural misassignments being reported every year. Herein, we will present the main techniques that have been used in AC reassignments of natural products over the last 10 years, along with some selected examples. Special attention will be paid to the strengths and weaknesses of each approach. With this, we expect to provide the readers with critical information to help them to choose the appropriate methods for correct AC determinations.

Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.
RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.

Abstract Taxonomic and cytogenetic aspects of Proceratophrys have not been thoroughly clarified in the literature; thus, the objective of the present study was to provide unprecedent karyotype data regarding P. schirchi, P. laticeps and P. melanopogon. Additionally, the karyotype of P. boiei (2n = 22) and its ZZ / ZW sex chromosome system was analyzed for different populations of southeastern and southern Brazil. All Proceratophrys species have a diploid number of 2n = 22 chromosomes. In P. schirchi, a strong C-band was found in the long arm in one of the homologues of the pair 8 in female metaphasic cells, denoting that this chromosome pair could represent the heteromorphic sex chromosome in a ZZ / ZW sex system. Despite the conserved number of chromosomes, there are considerable chromosomal differences in P. melanopogon and P. boiei (southern Brazil), strongly differentiating them cytogenetically from other species of the genus. Moreover, with the confirmation of chromosomal heteromorphism related to sexual differentiation in P. boiei and the possible description of this system in P. schirchi, the Proceratophrys genus can be regarded as an interesting group for evolutionary studies and sex chromosome differentiation in anurans.

ABSTRACT This paper provides a revision of the three smallest subgenera of Deltochilum, all endemic to the Atlantic Forest of South America. Deltochilum (Euhyboma) and D. (Rubrohyboma) are monospecific taxa, composed of D. brasiliense (Castelnau, 1840) and D. rubripenne (Gory, 1831), respectively, whereas D. (Parahyboma) is composed of two allopatric species, D. furcatum (Castelnau, 1840) and D. granulosum Paulian, 1933. Lectotypes for D. brasiliense and D. rubripenne are designated. Each species is analyzed as follows: a detailed literature review, a diagnosis, description, illustrations of key morphological characters, list of material examined, and geographic distribution. An improved identification key to the subgenera of Deltochilum is presented.

ABSTRACT This paper discusses the potential risk that COVID-19 generates for the development of enamel defects. This hypothesis was built based on the etiopathogenesis of enamel defects and the relationship with the symptom's characteristic of COVID-19. Pregnancy is a critical period for the child's development; exposure to pathological agents can cause systemic imbalances and risks of adverse perinatal and prenatal outcomes. The main clinical symptoms of this disease and its association with that dental outcome were considered. Fever, breathing, cardiovascular disorders, and diarrhea were related as potential etiological factors of ameloblast metabolism imbalance, which can interfere qualitatively and quantitatively in the development, maturation and mineralization of the tooth enamel. Molecular disorders derived from COVID-19, as well as their clinical symptoms, can be considered potential risk factors for the development of enamel defects. Individuals with enamel defects experienced high stress levels during pregnancy or early childhood. The approach adopted may help build new research to ensure understanding of the etiology of the development of dental enamel defects and its relationship with COVID-19. However, longitudinal studies need to be conducted to confirm the association between COVID-19 and adverse events during pregnancy.

Abstract: This paper describes the history, objectives and methods used by the nine Brazilian cohorts of the RPS Brazilian Birth Cohorts Consortium (Ribeirão Preto, Pelotas and São Luís) Common thematic axes are identified and the objectives, baseline periods, follow-up stages and representativity of the population studied are presented. The Consortium includes three birth cohorts from Ribeirão Preto, São Paulo State (1978/1979, 1994 and 2010), four from Pelotas, Rio Grande do Sul State (1982, 1993, 2004 and 2015), and two from São Luís, Maranhão State (1997 and 2010). The cohorts cover three regions of Brazil, from three distinct states, with marked socioeconomic, cultural and infrastructure differences. The cohorts were started at birth, except for the most recent one in each municipality, where mothers were recruited during pregnancy. The instruments for data collection have been refined in order to approach different exposures during the early phases of life and their long-term influence on the health-disease process. The investigators of the nine cohorts carried out perinatal studies and later studied human capital, mental health, nutrition and precursor signs of noncommunicable diseases. A total of 17,636 liveborns were recruited in Ribeirão Preto, 19,669 in Pelotas, and 7,659 in São Luís. In the studies starting during pregnancy, 1,400 pregnant women were interviewed in Ribeirão Preto, 3,199 in Pelotas, and 1,447 in São Luís. Different strategies were employed to reduce losses to follow-up. This research network allows the analysis of the incidence of diseases and the establishment of possible causal relations that might explain the health outcomes of these populations in order to contribute to the development of governmental actions and health policies more consistent with reality.
Resumen: El trabajo describe la historia, objetivos y métodos usados por nueve cohortes brasileñas del RPS Consorcio de Cohortes de Nacimiento. Se identificaron los ejes temáticos comunes y los objetivos, así como los periodos de referencia, la presentación del estadio de seguimiento y representatividad de la población estudiada. El consorcio incluye tres cohortes de nacimiento de Ribeirão Preto, Estado de São Paulo (1978/1979, 1994 y 2010), cuatro de Pelotas, Estado del Rio Grande do Sul (1982, 1993, 2004 y 2015), y dos de São Luís, Estado del Maranhão (1997 y 2010). Las cohortes cubren tres regiones de Brasil, de tres estados distintos, con marcadas diferencias socioeconómicas, culturales y de infraestructura. Las cohortes comenzaron con el nacimiento, excepto para la más reciente en cada municipio, donde las madres fueron reclutadas durante la gestación. Los instrumentos para la recogida de datos han sido depurados, con el fin de realizar una aproximación a diferentes exposiciones durante las fases tempranas de la vida y su influencia a largo plazo en el proceso de salud-enfermedad. Se incluyeron a los investigadores de las nueve cohortes, donde se llevaron a cabo estudios perinatales, así como los recursos humanos analizados posteriormente, al igual que la salud mental, nutrición y signos precursores de enfermedades no comunicables. Un total de 17.636 nacidos vivos fueron reclutados en Ribeirão Preto, 19.669 en Pelotas, y 7.659 en São Luís. En los estudios que comenzaron durante el embarazo, 1.400 mujeres embarazadas fueron entrevistadas en Ribeirão Preto, 3.199 en Pelotas, y 1.447 en São Luís. Se usaron diferentes estrategias para reducir pérdidas, con el fin de realizar el seguimiento. Esta red de investigación permite el análisis de la incidencia de enfermedades y el establecimiento de posibles relaciones causales que podrían explicar los resultados de salud de estas poblaciones, con el fin de contribuir al desarrollo de acciones gubernamentales y políticas de salud más consistentes con la realidad.
Resumo: O artigo descreve a história, objetivos e métodos utilizados pelas nove coortes do Consórcio RPS de Coortes de Nascimento. São identificados eixos temáticos comuns, com apresentação dos objetivos, anos de linha de base, fases de seguimento e representatividade das populações de estudo. O Consórcio inclui três coortes de nascimento de Ribeirão Preto, Estado de São Paulo (1978/1979, 1994 e 2010), quatro de Pelotas, Estado do Rio Grande do Sul (1982, 1993, 2004 e 2015) e duas de São Luís, Estado do Maranhão (1997 e 2010). As coortes provêm de três regiões do Brasil, de três estados diferentes, com importantes diferenças socioeconômicas, culturais e de infraestrutura. As coortes foram iniciadas ao nascer dos participantes, exceto a mais recente em cada município, onde as mães foram recrutadas durante a gestação. Os instrumentos para a coleta de dados foram refinados para aproximar diferentes exposições na primeira infância e a influência, a longo prazo, no processo saúde-doença. Os investigadores das nove coortes realizaram estudos perinatais e depois examinaram o capital humano, saúde mental, nutrição e sinais percursores de doenças crônicas. Um total de 17.636 nascidos vivos foram recrutados em Ribeirão Preto, 19.669 em Pelotas e 7.659 em São Luís. Nas coortes que foram iniciadas durante a gestação, foram entrevistadas 1.400 gestantes em Ribeirão Preto, 3.199 em Pelotas e 1.447 em São Luís. Foram utilizadas diferentes estratégias para reduzir as perdas de seguimento. A rede de pesquisa do Consórcio permite analisar a incidência de doenças e identificar possíveis relações causais que podem explicar os desfechos de saúde nessas populações e contribuir para o desenvolvimento de medidas públicas e políticas de saúde que estejam mais de acordo com as respectivas realidades.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Abstract: This paper describes the history, objectives and methods used by the nine Brazilian cohorts of the RPS Brazilian Birth Cohorts Consortium (Ribeirão Preto, Pelotas and São Luís) Common thematic axes are identified and the objectives, baseline periods, follow-up stages and representativity of the population studied are presented. The Consortium includes three birth cohorts from Ribeirão Preto, São Paulo State (1978/1979, 1994 and 2010), four from Pelotas, Rio Grande do Sul State (1982, 1993, 2004 and 2015), and two from São Luís, Maranhão State (1997 and 2010). The cohorts cover three regions of Brazil, from three distinct states, with marked socioeconomic, cultural and infrastructure differences. The cohorts were started at birth, except for the most recent one in each municipality, where mothers were recruited during pregnancy. The instruments for data collection have been refined in order to approach different exposures during the early phases of life and their long-term influence on the health-disease process. The investigators of the nine cohorts carried out perinatal studies and later studied human capital, mental health, nutrition and precursor signs of noncommunicable diseases. A total of 17,636 liveborns were recruited in Ribeirão Preto, 19,669 in Pelotas, and 7,659 in São Luís. In the studies starting during pregnancy, 1,400 pregnant women were interviewed in Ribeirão Preto, 3,199 in Pelotas, and 1,447 in São Luís. Different strategies were employed to reduce losses to follow-up. This research network allows the analysis of the incidence of diseases and the establishment of possible causal relations that might explain the health outcomes of these populations in order to contribute to the development of governmental actions and health policies more consistent with reality.
