Abstract Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM). Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM. Methodology: This is a cross-sectional study with 851 patients treated in outpatient clinics of a university hospital who underwent ABPM examination from January 2004 to February 2012 in order to assess the presence and control of AH. The outcomes considered were the ABPM parameters. The variable of interest was CKD staging. Confounding factors included age, sex, body mass index, smoking, cause of CKD, and use of antihypertensive drugs. Results: Systolic BP (SBP) was associated with CKD stages 3b and 5, irrespective of confounding variables. Pulse pressure was only associated with stage 5. The SBP coefficient of variation was progressively associated with stages 3a, 4 and 5, while the diastolic blood pressure (DBP) coefficient of variation showed no association. SBP reduction was associated with stages 2, 4 and 5, and the decline in DBP with stages 4 and 5. Other ABPM parameters showed no association with CKD stages after adjustments. Conclusion: Advanced stages of CKD were associated with lower nocturnal dipping and greater variability in blood pressure. Introduction (BP AH (AH CKD. .

Resumo Introdução: A avaliação da pressão arterial (PA) tem impacto no manejo da hipertensão arterial (HA) na doença renal crônica (DRC). O portador de DRC apresenta padrão específico de comportamento da PA ao longo da monitorização ambulatorial da pressão arterial (MAPA). Objetivos: O objetivo do corrente estudo é avaliar as associações entre os estágios progressivos da DRC e alterações da MAPA. Metodologia: Trata-se de um estudo transversal com 851 pacientes atendidos nos ambulatórios de um hospital universitário que foram submetidos ao exame de MAPA no período de janeiro de 2004 a fevereiro de 2012 para avaliar a presença e o controle da HA. Os desfechos considerados foram os parâmetros de MAPA. A variável de interesse foi o estadiamento da DRC. Foram considerados como fatores de confusão idade, sexo, índice de massa corporal, tabagismo, causa da DRC e uso de anti-hipertensivos. Resultados: A PA sistólica (PAS) se associou aos estágios 3b e 5 da DRC, independentemente das variáveis de confusão. Pressão de pulso se associou apenas ao estágio 5. O coeficiente de variação da PAS se associou progressivamente aos estágios 3a, 4 e 5, enquanto o coeficiente de variação da pressão arterial diastólica (PAD) não demonstrou associação. O descenso da PAS obteve associação com estágios 2, 4 e 5, e o descenso da PAD, com os 4 e 5. Demais parâmetros da MAPA não obtiveram associação com os estágios da DRC após os ajustes. Conclusão: Estágios mais avançados da DRC associaram-se a menor descenso noturno e a maior variabilidade da pressão arterial. Introdução (PA HA (HA .

Abstract Objetivo: Avaliar a concordância da terapêutica com medicamentos modificadores de prognóstico (MMP) em pessoas com insuficiência cardíaca crónica com fração de ejeção reduzida (P-CICFEr), em cuidados de saúde primários (CSP) na região Centro de Portugal, com as diretrizes da Sociedade Europeia de Cardiologia (ESC) de agosto de 2021. Métodos: Estudo observacional transversal de uma amostra representativa do tamanho, intervalo de confiança de 95% e margem de erro de 8%, da população com CICFEr em 31/dezembro/2021. Foram estudados idade, sexo, ano de diagnóstico da introdução da Classificação Internacional para Cuidados Primários-2 (ICPC-2, K-77), anos desde o último ecocardiograma, MMPs para P-CICFEr e outras terapêuticas para P-CICFEr. Participaram, convidadas por conveniência, 11 Unidades de Saúde Familiar após parecer positivo da Comissão de Ética. Resultados: Num universo de n=2.381 pessoas com insuficiência cardíaca (PCIC) encontraram-se n=453 (19,0%) (P-CICFEr) estudando-se uma amostra representativa de n=133 (5,6%), n=95 homens (71,4%). Verificou-se prescrição de medicamentos inibidores do sistema renina-angiotensina-aldosterona (iSRAA) 91,0%, de betabloqueadores em 75,2%, de antagonistas mineralocorticoides em 40,6%, de inibidores da SGLT2 em 44,4%, de inibidores da neprilisina em 38,3% e de diuréticos de ansa em 72,2%. A terapêutica farmacológica quádrupla verificou-se em n=28 (21,1%) P-CICFEr e a tripla em n=38 (28,6%). Verificou-se idade média de 74,3±11,6 anos, 75,1±4,0 no homem e 76,6±6,0 na mulher, p=0,088. A mediana de tempo desde o diagnóstico ICPC-2 foi de 6,0 anos no homem e de 4,0 anos na mulher, p=0,031. O tempo mediano desde o último ecocardiograma foi de três anos, p=0,750. Conclusão: Os medicamentos modificadores de prognóstico, segundo as diretrizes mais recentes da ESC para a CICFEr, estavam subutilizados em 50,4% dos casos. Apesar dos resultados encontrados é necessária reflexão acerca das barreiras que os médicos possam encontrar para aplicar as diretrizes em P-CICFEr.
Resumo Objective: To evaluate the accordance of prognostic medicines prescription (PMP), for persons with chronic heart failure with reduced ejection fraction (P-CHFrEF), attended in primary health care units in Central Portugal, with the European Society of Cardiology (ESC) 2021 August, guidelines. To know about mean age, median time since the diagnosis and last echocardiogram performance in P-CHFrEF. Methods: Observational, cross-sectional study of a random size representative sample, 95% confidence interval, and 8% error margin of the P-CHFrEF of a population on 31st December 2021. Age, gender, year of International Classification for Primary Care-2 (ICPC-2, K-77) problem classification input data, years since the last echocardiogram, ongoing PMP and the use of other chronic heart failure (CHF) drugs were gathered. Data were obtained from 11 Portugal Primary Health Care Units, invited by convenience, after an Ethics Committee approval. Results: From a universe of n=2,381 persons with CHF, n=453 (19.0%) P-CHFrEF was found. A size representative sample of P-CHFrEF of n=133 (5.6%), n=95 males (71.4%) was studied. Prescription of a renin-angiotensin system inhibitor (RAAS-I) was ongoing in 91.0%, beta-blocker (BB) in 75.2%, mineralocorticoid antagonists (MRA) in 40.6%, inhibitors of the sodium-glucose cotransporter-2 (SGLT2i) in 44.4%, neprilisine inhibitors 38.3% and loop diuretics in 72.2%. The optimized medical quadruple therapy was established in 28 patients (21.1%) and the triple one in 38 (28.6 %). Mean age was of 74.3±11.6 years, males 73.4±11.0 and females 76.6±12.9, p=0.088. The median time since the diagnosis was 6.0 for men and 4.0 for women, p=0.031. The median time since the last echocardiogram was 3.0, p=0.750 between genders. Conclusion: According to the 2021 ESC guidelines, prognostic modifying medicines were underused for 50.4% of P-CHFrEF. Even with these results, a reflection must be made, on the barriers physicians encounter, to comply with the ESC guidelines in such patients.

Abstract Background: Pentalinon andrieuxii, is a medicinal plant used in Mayan folk medicine against leishmaniosis. It is an important source of terpenoids whose biosynthesis has been reported to be influenced by the ontogeny of the plant. Hypotheses: Flowering positively influences the production of urechitol A in Pentalinon andrieuxii. Studied species: Pentalinon andrieuxii (Müll. Arg.) B.F. Hansen & Wunderlin (Apocynaceae) Study site and dates: Mérida, Yucatán, Mexico, 2019 and 2020. Methods: Flowering was induced by exposing plants to temperatures above 32 °C. Plant tissue samples were collected before flowering induction and at full bloom and extracted with methanol. Analyses of the dichloromethane-soluble fraction of the crude extract by Gas Chromatography-Mass Spectrometry allowed the detection and quantification of urechitol A. Results: Flowering stage of P. andrieuxii has a positive influence on the production of urechitol A in the root of the plant, with the contents of the tri-nor-sesquiterpene increasing from a minimum of 43 to a maximum of 91 times during the flowering stage of plants, both transformed and wild type. Conclusions: P. andrieuxii perceives high temperatures as an important environmental cue to flower; flowering positively influences the production of urechitol A in the roots of the plant; production of the tri-nor-sesquiterpene is controlled by the plant.

ABSTRACT We conducted a study to evaluate the frequency of infection by Trypanosoma spp. in bats captured in wild and urban ecotopes in the Department of Atlántico in the Caribbean region of Colombia from March 2021 to May 2022. Bats were taxonomically identified, and sex, relative age, and reproductive conditions were determined. A blood sample was used for parasitological analysis and DNA extraction to amplify a region of the 18S rRNA. 125 bats were collected, with the most abundant families being Molossidae (62/125; 49.6%) and Phyllostomidae (43/125; 34.4%). Molossus molossus collected in wild habitats showed an infection frequency of 8.1% (5/61) and 4.1% (3/61) through parasitological and molecular analysis, respectively. In comparison, Noctilio albiventris collected in urban habitats showed an infection frequency of 16.6% (2/12) for both analyses. These findings represent the first records of M. molossus harboring trypanosomes for the Department of Atlántico and of N. albiventris harboring trypanosomes in Colombia.

Abstract The aim of this study was to evaluate the influence of adding quaternary ammonium methacrylates (QAMs) to experimental adhesives by assessing the degree of conversion (DC), cytotoxicity against keratinocytes and fibroblasts, and antibacterial activity against biofilm formation. Two QAMs were added to an experimental adhesive: dimethylaminododecyl methacrylate bromododecane (DMADDM) or dimethylaminododecyl methacrylate bromohexadecane (DMAHDM) at three concentrations each: 1, 2.5, and 5 wt.%. Experimental adhesive without QAMs (control group) and commercially available Transbond XT Primer (3M Unitek, Monrovia, California, USA) were used for comparisons. The adhesives were tested for DC, cytotoxicity against keratinocytes and fibroblasts, and antibacterial activity against biofilm formation. DC, cytotoxicity against fibroblasts, and antibacterial activity were analyzed using one-way ANOVA and Tukey’s multiple comparisons. Cytotoxicity against keratinocytes was evaluated using the Kruskal Wallis and Dunn’s post-hoc (α = 5%) tests. Transbond showed lower DC as compared to 5% DMAHDM, 1% DMADDM, and 5% DMADDM (p < 0.05). However, all groups presented proper DC when compared to commercial adhesives in the literature. In the evaluation of cytotoxicity against keratinocytes, Transbond induced higher viability than 2.5 wt.% groups (p < 0.05). Against fibroblasts, Transbond induced higher viability as compared to 5 wt.% groups (p < 0.05). DMAHDM at 5 wt.% reduced biofilm formation when compared to all the other groups (p < 0.05). Despite their cytotoxic effect against keratinocytes, gingival fibroblasts showed higher viability. DMAHDM at 5 wt.% decreased Streptococcus mutans viability. The incorporation of DMAHDM at 5 wt.% may be a strategy for reducing the development of white spot lesions.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract Legal reserve areas (LRAs) are a fundamental part of the Brazilian conservation strategy, together with permanent preservation areas. The LRAs are intended to maintain biodiversity and can be managed sustainably. When these areas are home to ecosystems that depend on fire and grazing, such as native grasslands and savannas, management practices that are suitable for their conservation and for dealing with the effects of global climate change should be adopted. However, this subject is still poorly discussed in Brazil, and public policies are not clear on this matter. This review article describes the grassland and savanna ecosystems in Brazil, the legal aspects related to the management of LRAs, the current and future climate scenarios, and the relationship between climate and fire risk. It also presents a review about the use of fire and grazing in grassland and savanna ecosystems, the legal challenges related to their application in LRAs, and the use of geotechnologies to monitor these practices. The conclusion is that grazing and fire, as management tools, are adequate for LRA functions, as long as they are practiced in accordance with legal and scientifically based standards to avoid the negative effects of their incorrect use.

As ARLs são destinadas à manutenção da biodiversidade e podem ser manejadas de forma sustentável. Quando essas áreas abrigam ecossistemas dependentes de fogo e pastejo, como os campos nativos e as savanas, devem ser adotadas práticas de manejo adequadas à sua conservação e ao enfrentamento dos efeitos das mudanças climáticas globais. No entanto, esse assunto ainda é pouco discutido no Brasil, e as políticas públicas não são claras a esse respeito. Este artigo de revisão descreve os ecossistemas campestres e savânicos no Brasil, os aspectos legais relacionados com o manejo das ARLs, os cenários climáticos atuais e futuros, e a relação entre clima e risco de incêndios. Também apresenta uma revisão sobre o uso do fogo e do pastejo em ecossistemas campestres e savânicos, os desafios legais relativos à sua aplicação nas ARLs e o uso de geotecnologias no monitoramento destas práticas. Conclui-se que o pastejo e o fogo, como instrumentos de manejo, são adequados às funções das ARLs, desde que praticados segundo normas legais e cientificamente embasadas para evitar os efeitos negativos do seu uso equivocado.

Abstract Plants synthesize secondary metabolites as a means of survival and competition. These metabolites are a potential source of natural antioxidants that may promote activity, favoring the control of cellular damage caused by oxidative stress. The Annonaceae family occurs in tropical and subtropical regions worldwide. The medicinal benefits of plants from this family are caused by secondary metabolites present in these species. Thus, this study aimed to determine the total phenolic content, evaluate the antioxidant potential, and in vitro cytotoxicity of the leaf ethanolic extract from Ephedrantus amazonicus R. E. Fries. The phenolic content and antioxidant activity were evaluated by the Folin-Ciocalteu and DPPH methods, respectively. The assays were adapted for 96-well microplates, with absorbance reading at λ = 630 and 517 nm, respectively, using a UV-Vis spectrophotometer. The in vitro cytotoxicity assay was performed using fibroblasts (L929 cell line). The MS/MS analyses were performed through direct infusion using a LCQ Fleet mass spectrometer equipped with APCI font and ion trap analyzer, in the positive and negative mode. A molecular network was created using the online workflow on the GNPS website (http://gnps.ucsd.edu). The phenolic content at 400μg was 25.24 ± 0.98μg.GAE/g, while the antioxidant activity showed an EC50 of 13.37±2.63 μg.mL-1. Dereplication led to the annotation of three flavonoids that may contribute to the observed antioxidant activity. The extract showed low cytotoxicity at the highest tested concentration (> 500μM). The results demonstrate that the extract from Ephedrantus amazonicus R.E. Fries leaves is a promising source of natural antioxidants. competition stress worldwide species Thus R E FolinCiocalteu Folin Ciocalteu methods respectively 96well well 96 microplates 63 51 nm UVVis UV Vis spectrophotometer L929 L (L92 line. line . line) MSMS MS analyzer mode http//gnps.ucsd.edu. httpgnpsucsdedu http //gnps.ucsd.edu gnps ucsd edu (http://gnps.ucsd.edu) μg 2524 25 24 25.2 098μgGAEg μgGAEg 0 98μg GAE g 0.98μg.GAE/g EC EC5 1337263 13 37 2 13.37±2.6 μg.mL1. μgmL1 μgmL μg.mL 1. mL 1 μg.mL-1 > ( 500μM. 500μM μM 500μM) RE R.E 9 6 5 L92 (L9 http//gnps.ucsd.edu gnpsucsdedu (http://gnps.ucsd.edu 252 25. 133726 3 13.37±2. mL1 μg.mL1 μg.mL- L9 (L 13372 13.37±2 1337 13.37± 133 13.37 13.3 13.

Abstract Studies have highlighted numerous benefits of ozone therapy in the field of medicine and dentistry, including its antimicrobial efficacy against various pathogenic microorganisms, its ability to modulate the immune system effectively, reduce inflammation, prevent hypoxia, and support tissue regeneration. However, its effects on dental extraction healing remain to be elucidated. Objective Therefore, this study aimed to evaluate the effects of systemically administered ozone (O3) at different doses in the healing of dental extraction sockets in rats. Methodology To this end, 72 Wistar rats were randomly divided into four groups after extraction of the right upper central incisor: Group C – control, no systemic treatment; Group OZ0.3 – animals received a single dose of 0.3 mg/kg O3; Group OZ0.7 – a single dose of 0.7 mg/kg O3; and Group OZ1.0 – a single dose of 1.0 mg/kg O3, intraperitoneally. In total, six animals from each group were euthanized at 7, 14, and 21 days after the commencement of treatment. Bone samples were harvested and further analyzed by descriptive histology, histomorphometry, and immunohistochemistry for osteocalcin (OCN) and tartrate-resistant acid phosphatase (TRAP) protein expression. Results All applied doses of O3 were shown to increase the percentage of bone tissue (PBT) after 21 days compared to group C. After 14 days, the OZ0.7 and OZ1.0 groups showed significantly higher PBT when compared to group C. The OZ1.0 group presented the most beneficial results regarding PBT among groups, which denotes a dose-dependent response. OCN immunostaining was higher in all groups at 21 days. However, after seven and 14 days, the OZ1.0 group showed a significant increase in OCN immunostaining compared to C group. No differences in TRAP+ osteoclasts were found between groups and time points. Conclusion Therefore, O3 therapy at higher doses might be beneficial for bone repair of the alveolar socket following tooth extraction. dentistry microorganisms effectively inflammation hypoxia regeneration However elucidated Therefore O (O3 end 7 incisor control treatment OZ03 OZ OZ0 3 OZ0. 03 0 0. mgkg mg kg OZ07 07 OZ10 OZ1 OZ1. 10 1 1. intraperitoneally total 2 histology histomorphometry (OCN tartrateresistant tartrate resistant TRAP (TRAP expression (PBT dosedependent dependent response points (O

ABSTRACT The Verbal Autopsy (VA) is a questionnaire about the circumstances surrounding a death. It was widely used in Brazil to assist in postmortem diagnoses and investigate excess mortality during the Coronavirus Disease 2019 (COVID-19) pandemic. This study aimed to determine the accuracy of investigating acute respiratory distress syndrome (ARDS) using VA. This is a cross-sectional study with prospective data collected from January 2020 to August 2021 at the Death Verification Service of Sao Luis city, Brazil. VA was performed for suspected COVID-19 deaths, and one day of the week was randomly chosen to collect samples from patients without suspected COVID-19. Two swabs were collected after death and subjected to reverse transcription-polymerase chain reaction (RT-PCR) for SARS-CoV-2 detection. Of the 250 cases included, the VA questionnaire identified COVID-19-related ARDS in 67.2% (52.98% were positive for COVID-19). The sensitivity of the VA questionnaire was 0.53 (0.45–0.61), the specificity was 0.75 (0.64–0.84), the positive predictive value was 0.81 (0.72–0.88), and the negative predictive value was 0.44 (0.36–0.53). The VA had a lower-than-expected accuracy for detecting COVID-19 deaths; however, because it is an easily accessible and cost-effective tool, it can be combined with more accurate methods to improve its performance.

Abstract Despite the prevalence of substance use during pregnancy, studies focusing exclusively on Neonatal Intensive Care Units (NICU) admissions remain limited. This study investigates the impact of maternal use of tobacco, alcohol, and/or crack, on neonatal outcomes among infants admitted to three Brazilian NICUs. Additionally, the investigation explores the impact of substance use on DNA damage in newborns. Over a one-year period, data from 254 newborns were collected through medical records, accompanied by blood samples. Findings revealed that 16.1% of newborns had mothers reporting substance use during pregnancy. Significant associations were found between maternal substance use and adverse neonatal outcomes, including low birth weight, preterm birth, and sexually transmitted infections. Maternal variables linked to substance use encompassed non-white skin color, low education, non-masonry housing, lower income, diseases in other children, and fewer prenatal consultations. Notably, neonatal DNA damage showed no significant association with substance use. Our results underscore the substantial impact of maternal substance use on NICU-admitted infants, emphasizing the necessity for targeted interventions that address both neonatal health and maternal well-being, thereby underscoring the crucial role of comprehensive care in NICU settings. pregnancy (NICU limited tobacco alcohol andor or crack NICUs Additionally oneyear one year period 25 records samples 161 16 1 16.1 weight infections nonwhite non white color education nonmasonry masonry housing income children consultations Notably NICUadmitted wellbeing, wellbeing well being, being well-being settings 2 16.
