ABSTRACT Coffee is a beverage that is widely consumed throughout the world, especially in Brazil. Its high market value makes it a prime target for fraud. To combat this fraud, different methods have been developed and improved over the years to detect potential adulterants in coffee and guarantee its authenticity. Nevertheless, these methods still pose a challenge. Therefore, this work aimed to identify adulteration markers in roasted and ground Arabica coffee using high-performance liquid chromatography (HPLC) to determine the flavonoid and phenolic acid profile. Samples of Arabica coffee beans and defective coffee beans were adulterated with coffee husks by preparing mixtures in different proportions (97:3, 90:10, 80:20 % w/w), which were then subjected to chromatographic and chemometric analyses, including principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). Using the phenolic compounds associated with chemometric methods, protocatechuic acid was identified as a marker of adulteration in roasted and ground coffee with Arabica coffee husks, even at low adulterant concentrations (3 %). world Brazil fraud authenticity Nevertheless challenge Therefore highperformance performance HPLC (HPLC profile 973, 973 97 3, 3 (97:3 9010, 9010 90 10, 10 90:10 8020 80 20 80:2 w/w, ww w/w , w w/w) analyses PCA (PCA PLSDA.

ABSTRACT Objective: To evaluate the factors associated with the fear of dental students infecting their relatives with COVID-19 as a result of clinical practice. Material and Methods: Online questionnaires were sent by e-mail and social media to dental students from a Brazilian School of Dentistry. The outcome was "fear of infecting the family." The independent variables were sociodemographic data, personal protective equipment use, adoption of infection control measures, and knowledge and feelings about the pandemic and the future of Dentistry. Data analysis used Pearson's Chi-square and Fisher's exact tests (p≤0.05). Results: With 65 participants, the prevalence of fear was 61.5%. Measures to prevent COVID-19, such as frequent hand cleansing (p=0.028) and avoiding the use of aerosol-generating instruments (p=0.027), not having or not knowing if they have been infected by the disease (p=0.038), and feelings of more significant anxiety during the pandemic period (p=0.047), and that Dentistry will undergo major post-pandemic changes (p=0.020) were associated with fear. Conclusion: Changes in behavior about biosafety and feelings of anxiety and uncertainty about the disease were associated with the dental students' fear of infecting their relatives with COVID-19 as a result of clinical practice.

Abstract Adjustments in Brazilian livestock are necessary to minimize greenhouse gas (GHG) emissions, since the largest source of methane comes from ruminants’ enteric fermentation, and of carbon from deforestation. Low-carbon agriculture technologies (LCAT) contribute to mitigating these emissions and this study evaluates the role of these technologies on ruminant forage production in Caatinga. A Strength, Weakness, Opportunity, and Threats analysis was used to elucidate the main features, followed by an Analytic Hierarchical Process, ranking the LCAT, and a risk analysis. Integrated Crop-Livestock-Forest System (ICLFS) is the most recommended technology, followed by Sustainable Forest Management (SFM) and Recovery of Degraded Areas with Pastures (RDA-P). The results can aid in the choice of the LCAT to be implemented by the smallholder in Caatinga, demonstrating the need to strengthen rural technical assistance, so that there is a real benefit to the producer and the environment.

ABSTRACT Objective Patients with cancer often undergo multiple extended treatments that decrease their quality of life. However, the quality of life of women with breast cancer after they undergo treatment remains underexplored in Brazil. Therefore, this study determined sociodemographic, behavioral, and clinical factors related to the post-treatment quality of life of women with breast cancer. Methods This cross-sectional study involved 101 women diagnosed with breast cancer between 2014 and 2016 and treated at a Brazilian Oncology Reference Service. Data were collected from them using face-to-face surveys. Quality of life was evaluated using the European Organization for the Research and Treatment of Cancer Core Quality of Life questionnaire (EORTC QLQ-C30) and EORTC Breast Cancer-specific Quality of Life questionnaire (EORTC QLQ-BR23). The data collected were analyzed using Student’s t-test and Mann-Whitney U test. Results The median score on the global health, functional, and symptom scales of the EORTC QLQ-C30 was 75.00 (Interquartile range=33.33), 75.99 (Standard deviation [SD]=19.26), and 19.67 (SD=16.91), respectively. The mean score on the functional and symptom scales of the EORTC QLQ-BR23 was 61.89 (SD=17.21) and 20.12 (SD=16.94), respectively. Furthermore, higher post-treatment quality of life was found to be associated with being aged 50 or more, being Black, having eight or more years of education, having a partner, having a paying job, receiving treatment from the private healthcare system, having a higher income, living in the municipality where healthcare services are availed, engaging in physical activity, not smoking, being more religious, having more social support, not being overweight, having no comorbidities, and undergoing lumpectomy. Conclusion Sociodemographic, behavioral, and clinical factors significantly impact the quality of life of women who undergo breast cancer treatment. Implementing interventions that improve health and reducing inequalities in the access to healthcare services can improve the quality of life of these patients.

abstract This paper composes dialogues between indigenous anthropology and the anthropology of fishing communities. It analyzes the productive techniques and bodily experiences that women potters and women shellfish gatherers weave with the mud in its sensitive and conceptual aspects. It starts from the notion of mud/clay as a living entity that has singular material, historical and affective dynamics in each ethnographic context. Thus, it goes through narratives of women from the Kichwa Lamas communities in the Peruvian Amazon and the Island of Itaparica on the Brazilian Atlantic coast who, in the interstices of the anthropo/capitalocene, persist in the paths of the mud and the moon. aspects mudclay clay material context Thus who anthropocapitalocene anthropo capitalocene anthropo/capitalocene moon

Abstract This article deals with the kinship relationships woven by women in the daily activities of mariscagem (collecting/catching shellfish and crustaceans). The central focus of our analysis is the production of kin between houses and the tide through the daily and ancestral exchanges of a know-how: shellfish gathering. Based on ethnography carried out among shellfish gatherers on the island of Matarandiba (BA), we seek to understand the extent to which the tide, in its temporal, spatial and biosocial sense, can make up the house/body conjunction. We analyze how kinship relationships are woven into the circulation that takes place between the house and the tide through the rhythm of shellfish gathering. We propose a narrative based on the trajectory of the comadres marisqueiras, focusing mainly on the affective relationships these women have, rooted in the mangrove swamp. collecting/catching collectingcatching collecting catching crustaceans. crustaceans . crustaceans) knowhow know know-how gathering BA, BA , (BA) temporal sense housebody body conjunction marisqueiras have swamp (BA

Resumo Enterococcus faecalis, causa comum de infecções nosocomiais, é frequentemente associado a infecções endodônticas. Entretanto, há poucos estudos de caracterização genética das linhagens mais associadas aos canais radiculares. O objetivo deste estudo foi avaliar a relação genética entre isolados de E. faecalis de infecções endodônticas primárias no sudeste do Brasil para testar a hipótese de clones infectando indivíduos não relacionados e examinar o perfil de resistência antimicrobiana. A relação genética de 32 E. faecalis endodônticos foi obtida pela técnica de tipagem de sequências multilocus (MLST). Esses isolados foram coletados de pacientes não relacionados com infeção endodôntica primária tratados no Brasil entre 2010 e 2023. Teste de suscetibilidade antimicrobiana foi realizado utilizando a técnica de difusão em disco de acordo com o Clinical Laboratory Standard Institute (CLSI). Foram detectados 12 tipos de sequência (STs), dos quais 8 STs continham apenas um isolado. Clones de ST 30, ST 40, ST 97 e ST 397 foram encontrados, com uma elevada frequência deste último (15/32). A suscetibilidade aos agentes antimicrobianos testados variou, com a maior percentagem de resistência observada para a clindamicina (100%), tetraciclina (34,4%), azitromicina (31,2%) e ciprofloxacina (19,2%). Um isolado era multirresistente. O MLST de E. faecalis endodônticos revelou clones infectando diferentes indivíduos em diferentes cidades, com até 10 anos de intervalo, com alta ocorrência do ST 397. Portanto, existe uma linhagem predominante de E. faecalis associada a infecções endodônticas no sudeste do Brasil. Estes dados, juntamente com a literatura, levantam a preocupação de que possam existir linhagens especializadas em infecções endodônticas. nosocomiais Entretanto radiculares E 3 MLST. .

Abstract Enterococcus faecalis is a common cause of nosocomial infections and is frequently associated with endodontic infections. However, there is a scarcity of studies addressing the genetic characterization of E. faecalis lineages most commonly associated with root canals. The aim of this study was to assess the genetic relatedness of E. faecalis strains from primary endodontic infections in Southeast Brazil, test the hypothesis of clones infecting unrelated individuals, and examine the antimicrobial resistance profile. The genetic relationship of 32 endodontic E. faecalis isolates was investigated using multilocus sequence typing (MLST). These isolates were collected from unrelated patients with primary endodontic infections treated in Brazil between 2010 and 2023. Antimicrobial susceptibility testing was performed using the disk diffusion method in accordance with the Clinical Laboratory Standards Institute guidelines. Twelve sequence types (STs) were detected, of which eight STs contained only a single strain. Clones of ST 30, ST 40, ST 97, and ST 397 were identified, with a notably high frequency of ST 397 (15/32). Susceptibility to the antimicrobial agents tested varied, with the highest resistance rates observed for clindamycin (100%), tetracycline (34.4%), azithromycin (31.2%), and ciprofloxacin (19.2%). One isolate was found to be multidrug-resistant. MLST analysis of endodontic E. faecalis revealed clones infecting different individuals in various cities over a span of up to 10 years, with a high occurrence of ST 397. Therefore, there appears to be a predominant E. faecalis lineage associated with endodontic infections in Southeast Brazil. These findings, together with existing literature, raise concerns that certain lineages may be specialized in causing endodontic infections. However E canals profile 3 MLST. .

Abstract The present article aimed to analyze the association between sociodemographic and hospitalization characteristics with the outcome of indigenous and non-indigenous pregnant and postpartum women, as well as factors associated with deaths among indigenous women hospitalized for Severe Acute Respiratory Syndrome (SARS) due to COVID-19 in Brazil. This is a cross-sectional and analytical study, with secondary data of pregnant and postpartum women of reproductive age, classified into race/skin color (indigenous and non-indigenous), extracted from the Obstetric Observatory, which uses data from the Influenza Epidemiological Surveillance Information System. The outcome variables were analyzed using the chi-square test or Fisher’s exact test, and logistic regression was performed for the factors associated with the death of indigenous people. The highest proportion of deaths occurred among non-indigenous women who were in the 2nd trimester of pregnancy (99.7%), who lived in urban/peri-urban areas (99.8%), as well as in the South/Southeast (99.8%) and Northeast (99.5%) regions.

Resumen El objetivo de este manuscrito es analizar la asociación entre las características sociodemográficas y de hospitalización con el resultado de gestantes y puérperas indígenas y no indígenas y los factores asociados a las muertes entre las mujeres indígenas hospitalizadas por Síndrome Respiratorio Agudo Severo (SRAS) debido a COVID-19 en Brasil. Se trata de un estudio transversal, analítico, con datos secundarios de gestantes y puérperas en edad reproductiva, clasificadas por raza/color de piel (indígenas y no indígenas), extraídos del Observatorio Obstétrico, que utiliza datos del Sistema de Información de Vigilancia Epidemiológica de la Gripe. Las variables se analizaron con el resultado mediante la prueba de chi-cuadrado o la prueba exacta de Fisher y se realizó una regresión logística para los factores asociados a la muerte entre los indígenas. La mayor proporción de muertes ocurrió entre las mujeres no indígenas que estaban en el segundo trimestre del embarazo (99,7%), vivían en áreas urbanas/periurbanas (99,8%) y en las regiones Sur/Sureste (99,8%) y Noreste (99,5%). Las mujeres indígenas que vivían en zonas rurales y en las regiones Norte y Centro-Oeste tenían más probabilidades de morir que las mujeres indígenas de zonas urbanas y de las regiones Sur/Sureste.

Abstract The study evaluated the use of nano copper in semi-purified diets for laying quails and its effect on performance, metabolic state, and bioavailability. A total of 160 (180-days-old) quails were distributed in a completely randomized design, in a 3x3+1 factorial. The copper sources used were copper sulfate, copper oxide, and nano copper oxide, at levels of 200, 400, and 800 ppm each, totaling nine treatments plus a negative control (with no copper inclusion). The following variables were determined: weight gain, feed intake, egg production, egg weight, hemoglobin, hematocrit, Cu in the tissues and Cu bioavailability. Data were subjected to analysis of variance at 5% probability. The effect of sources and levels, as well as the interaction between the factors were evaluated. When interaction was observed, the effect of sources was evaluated separately by the Tukey’s test and the effect of levels by regression, both at 5% probability. Copper nano oxide can be used at up to 800 ppm in the diet of laying quails without altering the productive performance, and with higher bioavailability than conventional copper oxide. Hemoglobin increases with the inclusion of 200 and 400 ppm of nano copper oxide and the hematocrit with 400 ppm. semipurified semi purified performance state 16 180daysold daysold 180 days old (180-days-old design 3x31 x 3x3 1 3x3+ factorial sulfate 80 each inclusion. . inclusion) determined gain intake production hemoglobin 5 probability observed Tukeys Tukey s regression 20 40 18 3x 8 2 4

Abstract In 2015-2016, the Zika virus (ZIKV) caused a major epidemic in the Americas, increasing cases of microcephaly and Guillain-Barré syndrome. During this period, the discovery of ZIKV sexual transmission intensified studies on the impact of this virus on the reproductive organs. For this study, 2-month-old male BALB/c mice were infected with 1.26 x 106 PFU/mL of ZIKV in solution via the intravenous route. After three, seven, and fourteen days post-infection (DPI), blood and testicle samples were obtained to detect ZIKV RNA. The authors observed that the infected animals had slower weight gain than the control group. Viremia occurred only at 3DPI, and the ZIKV RNA was detected in one testis sample at 7DPI. The histopathological analysis of this organ revealed intense disorganization of the seminiferous tubules' structure, inflammatory infiltrate, necrosis, hemorrhage, fluid accumulation, congestion of blood vessels, and reduced sperm count. Ultrastructural analysis showed nuclear changes in tubule cells, activation of interstitial cells, and morphological changes in spermatozoa, in addition to fragmentation and decreased electron density of the genetic material of these cells. Thus, despite causing predominantly asymptomatic infections, ZIKV can cause significant subclinical and transient damage, including to male reproductive organs. 20152016, 20152016 2015 2016, 2016 2015-2016 (ZIKV Americas GuillainBarré Guillain Barré syndrome period organs study 2monthold monthold 2 month old BALBc BALB c 126 1 26 1.2 10 PFUmL PFU mL route three seven postinfection post infection DPI, DPI , (DPI) group 3DPI 7DPI tubules structure infiltrate necrosis hemorrhage accumulation vessels count cells spermatozoa Thus infections damage 2015201 201 2015-201 12 1.

RESUMO Introdução: Considerando o aumento da incidência de diabetes pós-transplante e o elevado impacto cardiovascular entre os receptores de transplantes, este facto faz com que o uso de inibidores de SGLT2 nesse grupo seja atrativo devido aos seus benefícios cardiovasculares e renoprotetores. No entanto, há escassez de evidência nos receptores de transplante renal com diabetes devido a preocupações com possíveis danos ao enxerto renal e efeitos adversos. Métodos: Este estudo retrospectivo foi elaborado para avaliar a eficácia e segurança dos inibidores de SGLT2 em receptores de transplante renal (KTRs). O foco principal foi avaliar o seu impacto em parâmetros como níveis de hemoglobina A1c, índice de massa corporal (IMC), perfil lipídico, níveis de hemoglobina, função do enxerto renal (taxa de filtração glomerular estimada) e relação proteína/creatinina urinária. Resultados: Um total de 75 pacientes receptores de transplante renal foram incluídos em nossa investigação. O estudo abrangeu um período de observação mediano de 18 (2,0–71,0) meses. A taxa média de filtração glomerular estimada no início foi de 61,9 (26–120) mL/min/1,73 m2 e permaneceu estável durante o acompanhamento. A mediana da HbA1c diminuiu de 7,5 para 7,0% (IC 95%; p<0,002). A melhora significativa no IMC (IC 95%; p<0,001) e no perfil lipídico (IC 95%; p<0,05) também foram observados. A taxa média de hemoglobina no início foi de 13,5g/dL e melhorou modestamente no final do acompanhamento para 13,7g/dL (p=0,12). Em relação à relação proteína/creatinina urinária, os níveis aumentaram ligeiramente, mas não significativamente [+0,05 g/g (p=0,9)]. Numa análise de subgrupo post-hoc, a taxa de infecções do trato urinário foi baixa (10%). Nenhum outro efeito colateral foi observado durante o curso do tratamento. Conclusões: Este estudo demonstra que a administração de inibidores de SGLT2 é viável e bem tolerada, sem efeitos colaterais notáveis em receptores de transplante renal. No entanto, a questão de saber se a inibição do SGLT2 pode efetivamente reduzir a mortalidade cardiovascular e melhorar a sobrevida do enxerto nesses pacientes permanece a ser explorada em estudos subsequentes.

ABSTRACT Introduction: Considering the rising occurrence of posttranplant diabetes and the elevated cardiovascular burden among transplant recipients, the utilization of SGLT2 inhibitors (SGLT2i) in this group is appealing because of their cardiovascular and renoprotective benefits. Nevertheless, there is a scarcity of evidence for diabetic kidney transplant recipients (DKTRs) owing to concerns about potential renal graft damage and adverse effects. Methods: This retrospective study was devised to assess the effectiveness and safety of SGLT2i in kidney transplant recipients (KTRs). The main focus was on evaluating their impact on parameters such as haemoglobin A1c levels, body mass index (BMI), lipid panel, haemoglobin levels, renal allograft function (estimated glomerular filtration rate) and urirnary protein-to-creatinine ratio. Results: A total of 75 renal transplant patients were included in this investigation. The study spanned a median observation period of 18 (2.0–71.0) months. Median estimated glomerular filtration rate at baseline was 61,9 (26–120) mL/min/1.73 m2 and remained stable throughout the follow-up. Median HbA1cdecreased from 7.5 to 7.0% (95% CI; p<0,002). A significant improvement in BMI (95% CI; p<0,001) and lipid panel (95% CI; p<0,05) were also observed. Median haemoglobin rate at baseline was 13,5g/dL and modestly improved at end of follow-up to 13,7g/dL (p=0,12). Regarding urinary protein:creatinine ratio, levels slightly but not significantly rose [+0.05 g/g (p=0,9)]. In a post-hoc subgroup analysis, the rate of urinary tract infections was low (10%). No other side effects were observed during the treatment course. Conclusions: This study demonstrates that the administration of SGLT2i is viable and well-tolerated, with no notable side effects observed in KTRs. However, the question of whether SGLT2i can effectively lower cardiovascular mortality and enhance allograft survival in these patients remains to be explored in subsequent studies.

Abstract Borosilicate glass was developed to enhance the mechanical behavior and smoothness of dental zirconia as an alternative to conventional glaze. This study assessed the mechanical and optical properties of 3 mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) coated with borosilicate glass or a commercial glaze fired for an extended period of time. Disc-shaped 3Y-TZP zirconia specimens (Zpex, Tosoh) were sintered at 1550°C for 2 hours. The specimens were divided into three groups: as-sintered (control, C); commercial glaze (G); and borosilicate glass (SL). The glaze and borosilicate glass were applied over the zirconia and fired for 20 minutes at 950°C and 1200°C, respectively. Biaxial flexural strength, fractography, X-ray diffraction (XRD), roughness (Ra and Rz), fracture toughness (Vickers indentation method), color difference (∆E00), and translucency (TP00) analyses were conducted. The t-test or the one-way ANOVA and Tukey’s tests were used to analyze the data (α = 0.05). Flexural strength data were subjected to the Weibull analysis. The SL group exhibited the highest flexural strength (1025.8 MPa), whereas the C (859.41 MPa) and G (816.0 MPa) groups exhibited similar values. The SL group also had the highest characteristic strength. The fracture origin in all groups was on the zirconia surface. XRD analysis revealed that the specimens from the SL group contained tetragonal, cubic, and monoclinic phases. The SL group presented the lowest surface roughness. Fracture toughness in the SL group was lower than in the C group, but similar to that observed in the G group. The translucency and color differences observed in the G and SL groups were similar. Borosilicate glass enhanced the flexural strength of 3Y-TZP, promoted the smoothest surface, and exhibited optical properties similar to those of the glaze. mol yttriastabilized yttria stabilized 3YTZP YTZP 3Y TZP Y (3Y-TZP time Discshaped Disc shaped Zpex, Zpex (Zpex Tosoh 1550C 1550 hours assintered control, control (control C) (G) SL. .

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.
