Validation of Gene Expression Patterns for Oral Feeding Readiness: Transcriptional Analysis of Set of Genes in Neonatal Salivary Samples.

BACKGROUND: Neonatal health assessment is crucial for detecting and intervening in various disorders. Traditional gene expression analysis methods often require invasive procedures during sample collection, which may not be feasible or ideal for preterm infants. In recent years, saliva has emerged as a promising noninvasive biofluid for assessing gene expression. Another trend that has been growing is the use of "omics" technologies such as transcriptomics in the analysis of gene expression. The costs for carrying out these analyses and the difficulty of analysis make the detection of candidate genes necessary. These genes act as biomarkers for the maturation stages of the oral feeding issue. METHODOLOGY: Salivary samples (n = 225) were prospectively collected from 45 preterm (<34 gestational age) infants from five predefined feeding stages and submitted to RT-qPCR. A better description of the targeted genes and results from RT-qPCR analyses were included. The six genes previously identified as predictive of feeding success were tested. The genes are AMPK, FOXP2, WNT3, NPHP4, NPY2R, and PLXNA1, along with two reference genes: GAPDH and 18S. RT-qPCR amplification enabled the analysis of the gene expression of AMPK, FOXP2, WNT3, NPHP4, NPY2R, and PLXNA1 in neonatal saliva. Expression results were correlated with the feeding status during sample collection. CONCLUSIONS: In summary, the genes AMPK, FOXP2, WNT3, NPHP4, NPY2R, and PLXNA1 play critical roles in regulating oral feeding and the development of premature infants. Understanding the influence of these genes can provide valuable insights for improving nutritional care and support the development of these vulnerable babies. Evidence suggests that saliva-based gene expression analysis in newborns holds great promise for early detection and monitoring of disease and understanding developmental processes. More research and standardization of protocols are needed to fully explore the potential of saliva as a noninvasive biomarker in neonatal care.

Do binge drinking adolescents have a greater number of traumatised teeth? A longitudinal study with 12-year-olds in Brazil.

BACKGROUND: Binge drinking has been linked to traumatic dental injury (TDI). Once drunk, adolescents are more prone to accidents, which may result in orofacial injury. AIM: This study evaluated the possible association of binge drinking with a number of traumatised teeth in a population of 12-year-old Brazilian adolescents in 2013 and 2015. DESIGN: This study was longitudinal, carried out with 588 adolescents at two moments, 2013 and 2015. TDI, overjet and lip protection were assessed by calibrated examiners. Binge drinking data were collected through the Alcohol Use Disorders Identification Test. Sociodemographic indicators were obtained through a questionnaire answered by the parents/guardians. The Poisson regression model with a random effects intercept was estimated. RESULTS: A higher prevalence of traumatised teeth was observed among adolescents who binge drink (IRR = 1.37; 95% CI: 1.05-1.80; p < .05). The prevalence was also significantly higher among adolescents in this age range with a ≥ 3-mm overjet and those with inadequate lip protection (IRR = 1.99; 95% CI: 1.44-2.76; p < .001 and IRR = 3.41; 95% CI: 2.57-4.53; p < .001, respectively). CONCLUSION: A greater number of traumatised teeth were found among adolescents who reported binge drinking and had severe overjet and inadequate lip coverage.

Production of solid acid catalyst using waste cigarette filters for esterification.

Cigarette filters were utilized as carbon source for the production of solid carbon acid catalysts. In this study, the process of carbonization and simultaneous sulfonation via hydrothermal treatment was employed. The catalysts were prepared by mixing cigarette filters and sulfuric acid at temperatures of 100, 150, and 190 °C for durations ranging from 2 to 8 h. It was observed that the highest conversion of oleic acid occurred when the catalyst was synthesized at 190 °C for 4 h. The optimized conditions for the esterification reaction using this catalyst included an oleic acid to methanol molar ratio of 1:12, a catalyst loading of 5 wt%, and a temperature of 100 °C for 1 h. Additionally, the catalyst was successfully reused four times without significantly impacting the reaction yield. These findings highlight a promising approach for the utilization of waste materials, with immediate implications for waste management practices and positive environmental impacts.

CO2 capture by microporous carbon based on Brazil nut shells.

The increase in burning, deforestation, and the exorbitant use of fossil fuels have contributed to the increase in carbon dioxide emissions; this gas is responsible for the intensification of the greenhouse effect and radical climate changes. In this way, it becomes necessary to find alternatives to reduce its emission. Porous carbon materials synthesized from lignocellulosic waste can be employed in technologies for capture and utilization of CO2 due to the advantages such as selectivity, low-cost synthesis, high surface area and pore volume, and thermal and chemical stability. Considering the availability of Brazil nut biomass residues in the Amazon region, this article proposes to synthesize activated carbon from the lignocellulosic residue using physical and chemical activation methods for CO2 capture. The analysis of N2 adsorption-desorption isotherms proves the predominance of a microporous structure when using the two synthesis methods described here. In physical activation, the surface area was 912 m2/g, while, in chemical activation, it was 1421 to 2730 m2/g. The sample treated via the chemical method (BS6-K1) showed better performance in CO2 adsorption, with adsorption results of 3.8 and 6 mmol/g of CO2 at 25 ℃ and 0 °C, respectively, at 101 kPa. CO2 adsorption capacity is due to the high volume of ultramicropores. It is believed that the microporous carbon material synthesized from Brazil nut residues is an alternative precursor for carbon materials used as CO2 capture.

Does religiosity impact binge drinking among early adolescents? A cross-sectional study in a city in Southeastern Brazil / A religiosidade impacta o binge drinking na adolescência precoce? Um estudo transversal em uma cidade do sudeste do Brasil

Abstract This study evaluated the association between religiosity and binge drinking in early adolescence. A cross-sectional study was conducted with adolescents aged 10-13 from Belo Horizonte, Brazil. Stratified random sampling was performed considering the administrative district and school year. Adolescents filled an AUDIT-C form, containing questions about religiosity and binge drinking by parents and their best friends. Adolescents' caregivers answered a form regarding socioeconomic issues. Descriptive analysis, univariate, and multivariate logistic regression were performed. A total of 650 adolescents participated in the study. The frequency of binge drinking was 13.7%. In the adjusted model, religiosity was not associated with binge drinking. The covariates associated were the age of 12-13 years (OR: 1.94; CI95%: 1.06-3.56; p=0.030), maternal binge drinking (OR: 3.12; CI95%: 1.76-5.52; p<0.001) best friend binge drinking (OR: 6.01; CI95%: 3.40-10.62; p<0.001) and nonnuclear family (OR: 1.80; CI95%: 1.01-3.23; p=0.045). The findings revealed that, for binge drinking, the main factors that influenced this decision were the best friend and maternal binge drinking and family structure, although the adolescents claimed to be religious.

Oral health issues in children and adolescents with vision impairment: A systematic review and meta-analysis.

BACKGROUND: Children and adolescents with vision impairment (VI) may be at increased risk of oral health issues, such as periodontal inflammation, poor oral hygiene, dental caries, and dental trauma, but this is inconclusive in the literature. AIM: To systematically review the literature to determine the main oral health issues of children and adolescents with VI compared to those without VI. DESIGN: Electronic and manual searches were performed to identify observational studies involving children and adolescents with and without VI, to determine and compare their oral health issues. The methodological quality was assessed using the Joanna Briggs Institute critical appraisal tool. Studies that had homogeneity of methods were incorporated into meta-analyses. RESULTS: Fifteen cross-sectional studies were included. Overall, most studies presented methodological flaws and high risk of bias. The meta-analysis showed that children and adolescents with VI were 3.86 times as likely to exhibit dental trauma (OR = 3.86, 95% CI = 2.63-5.68, I2  = 0%) and had higher/poorer values for plaque (MD = 0.80, 95% CI = 0.58-1.02, I2  = 96%), gingivitis (MD = 0.69, 95% CI = 0.02-1.37, I2  = 100%), calculus (MD = 0.04, 95% CI = 0.03-0.06, I2  = 0%), and oral hygiene indices (MD = 0.71, 95% CI = 0.24-1.18, I2  = 97%), as well as DMFS (MD = 0.90, 95% CI = 0.68-1.13, I2  = 26%). CONCLUSION: Across a wide array of assessments, children and adolescents with vision impairment had worse oral health outcomes than those without VI.

Incidence and risk factors for moderate/severe COVID-19 in rheumatic diseases patients on hydroxychloroquine: a 24-week prospective cohort.

OBJECTIVES: To evaluate the incidence of COVID-19 and its main outcomes in rheumatic disease (RD) patients on hydroxychloroquine (HCQ) compared to household cohabitants (HC). METHODS: This is a 24-week nationwide prospective multi-centre cohort with a control group without RD and not using HCQ. All participants were monitored through scheduled phone interviews performed by health professionals. Details regarding COVID-19 symptoms, and epidemiological, clinical, and demographic data were recorded on a specific web-based platform. COVID-19 was defined according to the Brazilian Ministry of Health criteria and classified as mild, moderate or severe. RESULTS: A total of 9,585 participants, 5,164 (53.9%) RD patients on HCQ and 4,421 (46.1%) HC were enrolled from March 29th, 2020 to September 30th, 2020, according to the eligibility criteria. COVID-19 confirmed cases were higher in RD patients than in cohabitants [728 (14.1%) vs. 427 (9.7%), p<0.001] in a 24-week follow-up. However, there was no significant difference regarding outcomes related to moderate/ severe COVID-19 (7.1% and 7.3%, respectively, p=0.896). After multiple adjustments, risk factors associated with hospitalisation were age over 65 (HR=4.5; 95%CI 1.35-15.04, p=0.014) and cardiopathy (HR=2.57; 95%CI 1.12-5.91, p=0.026). The final survival analysis demonstrated the probability of dying in 180 days after a COVID-19 diagnosis was significantly higher in patients over 65 years (HR=20.8; 95%CI 4.5-96.1) and with 2 or more comorbidities (HR=10.8; 95%CI 1.1-107.9 and HR=24.8; 95%CI 2.5-249.3, p=0.006, respectively). CONCLUSIONS: Although RD patients have had a higher COVID-19 incidence than individuals from the same epidemiological background, the COVID-19 severity was related to traditional risk factors, particularly multiple comorbidities and age, and not to underlying RD and HCQ.

Genetically determined variations of selenoprotein P are associated with antioxidant, muscular, and lipid biomarkers in response to Brazil nut consumption by patients using statins.

Several single nucleotide polymorphisms (SNPs) could indirectly, as well directly, influence metabolic parameters related to health effects in response to selenium (Se) supplementation. This study aimed to investigate whether the selenoprotein SNPs were associated with the response of Se status biomarkers to the Brazil nut consumption in patients using statins and if the variation in Se homoeostasis could affect antioxidant protection, lipid profile, muscle homoeostasis and selenoproteins mRNA. The study was performed in the Ribeirão Preto Medical School University Hospital. Thirty-two patients using statins received one unit of Brazil nut daily for 3 months. Body composition, blood Se concentrations, erythrocyte glutathione peroxidase (GPX) activity, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triacylglycerol (TAG), creatine kinase (CK) activity and gene expression of GPX1 and selenoprotein P (SELENOP) were evaluated before and after Brazil nut consumption. The volunteers were genotyped for SNP in GPX1 (rs1050450) and SELENOP (rs3877899 and rs7579). SNPs in selenoproteins were not associated with plasma and erythrocyte Se, but SNPs in SELENOP influenced the response of erythrocyte GPX activity and CK activity, TAG and LDL after Brazil nut consumption. Also, Brazil nut consumption increased GPX1 mRNA expression only in subjects with rs1050450 CC genotype. SELENOP mRNA expression was significantly lower in subjects with rs7579 GG genotype before and after the intervention. Thus, SNP in SELENOP could be associated with interindividual differences in Se homeostasis after Brazil nut consumption, emphasising the involvement of genetic variability in response to Se consumption towards health maintenance and disease prevention.

Concluiu-se que o consumo de bebidas alcoólicas misturadas com bebidas energéticas, a idade de 12-13 anos, o consumo em binge pela mãe e melhor amigo, a menor escolaridade materna, família não nuclear e a alta rede de amigos foram fatores associados ao binge drinking. A alta coesão na escola foi um possível fator de proteção e a religiosidade não esteve associada ao binge drinking na adolescência precoce.

The aim of this study was to assess the prevalence of binge drinking in early adolescence and its association with the consumption of alcohol mixed with energy drinks, religiosity and social capital. This is a cross-sectional study carried out with adolescents aged 10 to 13 years old enrolled in public schools in Belo Horizonte, Brazil. The random stratified sampling was performed, proportionally by administrative district and by school year. To select students, schools were randomly selected by region and all eligible students were invited to participate. A total of 650 adolescents participated in the study. Adolescents completed the Alcohol Use Disorders Identification Test (AUDIT-C), questions about drinking alcohol mixed with energy drinks, binge drinking by parents and best friend, questions about religiosity, and the social capital questionnaire for adolescents (QSC- AE). A form regarding socioeconomic issues was answered by the parents. Descriptive analysis, univariate and multiple logistic regression (p <0.05) were performed. The results were presented in the form of three articles. The first article addressed the association between the consumption of alcoholic beverages mixed with energy drinks and binge drinking, the second article the association between religiosity and binge drinking and the third article the association between social capital and binge drinking. The prevalence of binge drinking was 13.7%. In the adjusted model, consumption of alcohol mixed with energy drinks (OR: 6.13; 95% CI: 3.81-11.83; p< 0.001), binge drinking by the mother (OR: 2.88; CI 95 %: 1.59-5.24; p< 0.001), binge drinking by the best friend (OR: 4.28; 95% CI: 2.35-7.79; p< 0.001) and non-nuclear family (OR: 1.89; 95% CI: 1.03-3.48; p= 0.039) were associated with the outcome. Religiosity was not associated with binge drinking. The associated covariates were age 12-13 years (OR: 1.94; 95% CI: 1.06-3.56; p= 0.030), binge drinking by the mother (OR: 3.07; 95% CI: 1.73-5.46; p < 0.001); binge drinking by best friend (OR: 6.01; 95% CI: 3.40-10.62; p< 0.001) and non-nuclear family (OR: 1.80; 95% CI: 1.01-3.23 ; p=0.045). High social cohesion at school (OR: 0.41; 95% CI: 0.20-0.0.83; p=0.024), high network of friends (OR: 1.02; 95% CI: 0.20-0.83; p=0.013); binge drinking by best friend (OR: 6.21; 95% CI: 3.43-11.23; p<0.001); binge drinking by the mother (OR: 3.26; 95% CI: 1.80-5.89; p<0.001) and lower maternal education (OR: 2.69; 95% CI: 1.52-4.76; p=0.001 ) were associated with the outcome. It was concluded that the consumption of alcohol mixed with energy drinks, the age of 12-13 years, binge drinking by the mother and best friend, lower maternal education, non-nuclear family and high network of friends were factors associated with binge drinking. High school cohesion was a possible protective factor and religiosity was not associated with binge drinking in early adolescence.

Prevalence of oral health-related shame and associated factors among Brazilian schoolchildren.

The aim of the present study was to investigate the prevalence of oral health-related shame and the associated factors among 8-to-10-year-old Brazilian schoolchildren. A cross-sectional study was conducted with 388 children randomly selected from public and private schools of Diamantina, southeastern Brazil. In order to identify the feeling of shame, self-reports were collected through a single question, "In the last month, did you feel ashamed because of your teeth or mouth? Two calibrated examiners performed the clinical examination for dental caries (DMFT/dmft index), traumatic dental injuries (O' Brien), and malocclusion (Dental Aesthetic Index). Sociodemographic indicators were obtained through a questionnaire answered by the children's caregivers. Descriptive analysis, chi-square test, and hierarchical Poisson regression models were performed (95%CI; p < 0.05). The prevalence of shame was 38.1% (n = 148). The adjusted regression analysis demonstrated a significant association between shame and untreated dental caries (PR: 1.34; 95%CI: 1.04-1.74; p = 0.02), age of 10 years (PR: 1.36; 95%CI: 1.05-1.76; p = 0.01), and with parents with less than eight years of schooling (PR: 1.30; 95%CI: 1.00-1.68; p = 0.04). Older children with untreated dental caries and whose parents had lower education level presented a higher prevalence of oral health-related shame.

Determinant factors for immediate care seeking after traumatic dental injury among Brazilian children.

The present study aimed to evaluate the frequency of immediate care seeking after traumatic dental injury (TDI) in primary dentition and its association with the children's characteristics, socioeconomic status, and TDI characteristics. This was a cross-sectional study with dental records of children aged 9 months to 6 years who attended a reference center in TDI in primary dentition between 2007 and 2018. Immediate care seeking after TDI, child's characteristics, sociodemographic conditions and TDI characteristics were collected. Descriptive statistics and Poisson regression analysis with robust variance were performed (p < 0.05; 95%CI). Among the 493 dental records, 61.1% (n = 301) were of males and 50.5% (n = 249) were from children aged 2 years or less. More than one third of the sample (36.9%; n = 182) sought immediate care after TDI. Among the types of TDI, the prevalence of soft tissue injuries was 59.0% (n = 291), while 51.7% (n = 255) were hard tissue injuries and 54.0% (n = 266) were supporting tissue injuries. Immediate care seeking after TDI was higher in children who needed suture (PR: 1.39; 95%CI: 1.01-1.92. p = 0.039), had luxation (lateral, intrusion, or extrusion) (PR: 2.36; 95%CI: 1.36-4.08. p = 0.002) or avulsion (PR: 2.18; 95%CI: 1.28-3.70. p = 0.004). The need for suture, luxation (lateral, intrusion and extrusion), and avulsion were determinant factors for the immediate care seeking after TDI, regardless of the child's characteristics and socioeconomic status.

Chronic use of hydroxychloroquine did not protect against COVID-19 in a large cohort of patients with rheumatic diseases in Brazil.

BACKGROUND: There is a lack of information on the role of chronic use of hydroxychloroquine during the SARS-CoV-2 outbreak. Our aim was to compare the occurrence of COVID-19 between rheumatic disease patients on hydroxychloroquine with individuals from the same household not taking the drug during the first 8 weeks of community viral transmission in Brazil. METHODS: This baseline cross-sectional analysis is part of a 24-week observational multi-center study involving 22 Brazilian academic outpatient centers. All information regarding COVID-19 symptoms, epidemiological, clinical, and demographic data were recorded on a specific web-based platform using telephone calls from physicians and medical students. COVID-19 was defined according to the Brazilian Ministry of Health (BMH) criteria. Mann-Whitney, Chi-square and Exact Fisher tests were used for statistical analysis and two binary Final Logistic Regression Model by Wald test were developed using a backward-stepwise method for the presence of COVID-19. RESULTS: From March 29th to May 17st, 2020, a total of 10,443 participants were enrolled, including 5166 (53.9%) rheumatic disease patients, of whom 82.5% had systemic erythematosus lupus, 7.8% rheumatoid arthritis, 3.7% Sjögren's syndrome and 0.8% systemic sclerosis. In total, 1822 (19.1%) participants reported flu symptoms within the 30 days prior to enrollment, of which 3.1% fulfilled the BMH criteria, but with no significant difference between rheumatic disease patients (4.03%) and controls (3.25%). After adjustments for multiple confounders, the main risk factor significantly associated with a COVID-19 diagnosis was lung disease (OR 1.63; 95% CI 1.03-2.58); and for rheumatic disease patients were diagnosis of systemic sclerosis (OR 2.8; 95% CI 1.19-6.63) and glucocorticoids above 10 mg/ day (OR 2.05; 95% CI 1.31-3.19). In addition, a recent influenza vaccination had a protective effect (OR 0.674; 95% CI 0.46-0.98). CONCLUSION: Patients with rheumatic disease on hydroxychloroquine presented a similar occurrence of COVID-19 to household cohabitants, suggesting a lack of any protective role against SARS-CoV-2 infection.

Brain Tumor Heterogeneity

Tumor heterogeneity is the concept that different tumor cells provide distinct biomorphological lesions, gene expressions, proliferation, microenvironment and graduated capacity of metastatic lesions. Brain tumor heterogeneity has been recently discussed about the interesting interaction of chronic inflammation, microenvironment, epigenetics and glioma steam cells. Brain tumors remain a challenge with regards to medication and disease, due to the lack of treatment options and unsatisfactory results. These results might be the result of the brain tumor heterogeneity and its multiple resistance mechanisms to chemo and radiotherapy.

Toxoplasma gondii in domiciled dogs and cats in urban areas of Brazil: risk factors and spatial distribution.

Toxoplasma gondii is a highly prevalent zoonotic parasite in Brazil capable of infecting mammals and birds. The increase in the urban populations of pets and the narrowing of the human-animal relationship can facilitate the transmission of important public health zoonoses, such as toxoplasmosis. This study aimed to evaluate the frequency and spatial distribution of T. gondii infection and its risk factors in domiciled dogs and cats attended at the Jorge Vaitsman Institute, Rio de Janeiro. Serum samples from 400 dogs and 272 cats were evaluated by an indirect fluorescent antibody test (IFAT) for IgG anti-T. gondii antibodies. Epidemiological questionnaires were used to interview the animals' owners to identify risk factors for infection. Of the total, 34% (136/400) of dogs and 8.1% (22/272) of cats had anti-T. gondii antibodies. Breed (OR: 2.10-95%, CI 1.27-3.46) was a risk factor for dogs, while sex (OR: 3.40-95%, CI 1.10-10.52) and homemade food consumption (OR: 8.49-95%, CI 2.48-29.05) were risk factors for cats. Offal consumption was considered a risk factor for both species evaluated (OR: 2.74-95%, CI 1.38-5.43 for dogs; OR: 7.66-95%, CI 1.24-47.29 for cats). The spatial analysis showed that T. gondii seropositive animals were widely distributed in the metropolitan region of Rio de Janeiro state, with a concentration observed mainly in the west and north zones of Rio de Janeiro city. The results emphasize the importance of adopting prophylactic measures to control T. gondii transmission in domiciled dogs and cats in Rio de Janeiro, contributing positively to public health.

TITLE: Toxoplasma gondii chez les chiens et les chats domiciliés dans des zones urbaines du Brésil : facteurs de risque et répartition spatiale. ABSTRACT: Toxoplasma gondii est un parasite zoonotique très répandu au Brésil, capable d'infecter les mammifères et les oiseaux. L'augmentation des populations urbaines d'animaux de compagnie et le rétrécissement de la relation homme-animal peuvent faciliter la transmission de zoonoses importantes pour la santé publique, telles que la toxoplasmose. Cette étude visait à évaluer la fréquence et la distribution spatiale de l'infection à T. gondii et ses facteurs de risque chez les chiens et les chats domiciliés qui ont fréquenté l'Institut Jorge Vaitsman de Rio de Janeiro. Des échantillons de sérum de 400 chiens et 272 chats ont été évalués par un test d'immunofluorescence indirecte (IFAT) pour les anticorps IgG anti-T. gondii. Des questionnaires épidémiologiques ont été appliqués aux propriétaires des animaux pour identifier les facteurs de risque d'infection. Sur le total, 34 % (136/400) des chiens et 8,1 % (22/272) des chats avaient des anticorps anti-T. gondii. La race (OR : 2,10-95 %, IC 1,27-3,46) était un facteur de risque pour les chiens, tandis que le sexe (OR : 3,40-95 %, IC 1,10-10,52) et la consommation d'aliments faits maison (OR : 8,49-95 % IC 2,48-29,05) l'étaient pour les chats. La consommation d'abats a été considérée comme un facteur de risque pour les deux espèces évaluées (OR : 2,74-95 %, IC 1,38-5,43 pour les chiens; OR : 7,66-95 %, IC 1,24-47,29 pour les chats). L'analyse spatiale a montré que les animaux séropositifs pour T. gondii étaient largement répartis dans la région métropolitaine de l'État de Rio de Janeiro, avec une concentration observée principalement dans les zones ouest et nord de la ville de Rio de Janeiro. Les résultats soulignent l'importance d'adopter des mesures prophylactiques pour contrôler la transmission de T. gondii chez les chiens et les chats domiciliés à Rio de Janeiro, contribuant positivement à la santé publique.

Gender differences in traditional knowledge of useful plants in a Brazilian community.

Genders differ in traditional ecological knowledge (TEK) about plants, but how gender influences TEK sharing is still poorly understood. Here, we examined how gender is associated with the diversity, transmission, and structure of TEK. We tested whether women and men differ in terms of plant knowledge (species richness, α-diversity), knowledge heterogeneity (ß-diversity), and in the structure of social-ecological networks they form. The study was carried out in a suburban community in the city of Ouro Preto, Southeastern, Brazil. Using the snow-ball technique, semi-structured interviews, guided tours, and participant observation, we gathered information from 33 women and 33 men in the community. We collected information about their culture, social-economic profiles, and plant knowledge from which we identified 291 plant species in 10 use categories. Overall, our results indicated that the cognition and sharing of ethnobotanical knowledge are structured by gender. Women rated better in their plant knowledge repertory (greater α-diversity), while plant knowledge among men was more heterogeneous (greater ß-diversity), suggesting less information sharing among them. We observed that the network among women is more connected, exhibited greater information sharing, with a greater number of central individuals, who likely provide the cohesion and maintenance of TEK in the community. Our findings indicate how social-ecological networks can provide insights and information to unveil social patterns of knowledge transmission. Understanding how TEK is fostered and shared among community members will favor better planning of ethnobotanical studies, as well as inform decision-makers about strategies for the conservation of plant TEK.

Hérnia umbilical primária: melhor manejo operatório no adulto / Primary umbilical hernia: Best surgical management in adults

RESUMO: Modelo do estudo: Revisão sistemática. Objetivo: Avaliar se é facultativo ou imprescindível o uso de malha cirúrgica no reparo das pequenas hérnias umbilicais primárias, com orifício menor que 2 cm, a fim de oferecer melhores evidências aos cirurgiões e, assim, aprimorar o método cirúrgico e o seu desfecho. Métodos: Trata-se de uma revisão da literatura, cuja busca foi direcionada aos artigos que abordassem o manejo operatório das hérnias abdominais, sobretudo das hérnias umbilicais de pequeno tamanho. A pesquisa foi realizada nas bases de dados primárias PubMed, LILACS, Cochrane Library e Periódicos CAPES. Resultados: No total, foram incluídos quatro es-tudos. Foram avaliadas as taxas de recorrência, bem como as de complicações pós-operatórias após a correção da hérnia umbilical com e sem o uso de tela, observando-se o tamanho do defeito abdominal. Foi observada diminuição da recorrência das hérnias após o reparo com tela. No entanto, complicações, como infecção da ferida operatória, foram mais comumente observadas com o uso da prótese. Não houve consenso quanto ao uso da tela em hérnias menores que 1 cm. Conclusão: O uso de próteses pode vir a ser o tratamento de escolha no reparo das hérnias umbilicais primárias. Contudo, mais estudos são necessários para avaliar o papel dessa estratégia no manejo das hérnias menores que 1 cm (AU)

ABSTRACT: Study design: Systematic review. Objective: Evaluate whether surgical mesh is optional or essential for the repair small primary umbilical hernias, with an orifice smaller than 2 cm, in order to provide better evidence for surgeons, thus enhancing surgical method and its outcomes. Methods: This is a literature review, whose search was directed towards papers that depicted surgical management of abdominal hernias, especially small umbilical hernias. The research was carried out in the primary the primary databases PubMed, LILACS, Cochrane Library, and Periódicos CAPES. Results: A total of four studies were included. Recurrence rates, as well as postoperative complications, were assessed after an umbilical hernia was corrected with or without the use of a mesh, observing the size of the abdominal defect. A reduction in the re-occurrence of hernias was observed when using a mesh. However, complications, such as surgical site infection, were more commonly noticed with the use of the prosthe-sis. There was no consensus regarding the use of the mesh in hernias smaller than 1 cm. Conclusion: The use of surgical mesh may prove to be the treatment of choice for the repair of primary umbilical hernias. However, more studies are needed to evaluate the role of this strategy in the management of hernias smaller than 1 cm. (AU)

Complications following replantation of primary teeth: a case report / Complicações após reimplante de dentes decíduos: um relato de caso clínico

Abstract Introduction: the avulsion of primary teeth is a disturbing and unexpected event. Description: this report describes the clinical case of a three-year-old child who suffered an avulsion and replantation of the primary upper central incisors at the site of the injury. The guardians sought treatment for the child at the Federal University of Minas Gerais after the replantation. Four months later, the child suffered a new trauma and the replanted teeth presented advanced mobility, root resorption and fistula. The clinical conduct was extraction and rehabilitation with a fixed esthetic maintainer. Discussion: the literature describes two treatment options for avulsion of primary incisors: replantation and non-replantation. According to a recent systematic review, the difficulty in obtaining a consensus regarding the best clinical conduct is due, in part, to the scarcity of publications that present not only follow-ups with clinical success, but also with failures. The outcomes of replantation can be influenced by several factors. The time elapsed between replantation and splinting, and the new episode of trauma, negatively influenced the prognosis in the present case, leading to failure. Replantation of primary incisors is not yet evidence-based treatment. Therefore, this option must be chosen with caution and in ideal situations. It requires constant clinical and radiographic monitoring for evaluation of outcomes.

Resumo Introdução: a avulsão de dentes decíduos é um evento perturbador e inesperado. Descrição: o presente relato descreve o caso clínico de uma criança de três anos que sofreu avulsão e reimplante dos incisivos centrais superiores decíduos no local do acidente. Os responsáveis procuraram atendimento para a criança na Universidade Federal de Minas Gerais após reimplante. Quatro meses depois, a criança sofreu novo trauma e os dentes reimplantados apresentavam mobilidade avançada, reabsorção radicular e fístula. A conduta clínica foi extração e reabilitação com mantenedor estético fixo. Discussão: a literatura descreve duas opções de tratamento para avulsão de incisivos decíduos: o reimplante e o não reimplante. De acordo com revisão sistemática recente, a dificuldade de se obter um consenso sobre a melhor conduta clínica se deve, em parte, à escassez de publicações que apresentem não apenas acompanhamentos com sucesso clínico, mas também com falhas. O reimplante pode ser influenciado por vários fatores. O tempo decorrido entre o reimplante e a contenção, e o novo episódio de trauma, influenciaram negativamente o prognóstico do presente caso, levando ao insucesso. O reimplante de incisivos decí- duos ainda não é um tratamento baseado em evidências. Portanto, essa opção deve ser escolhida com cautela e em situações ideais. Requer monitoramento clínico e radiográfico para constante avaliação do desfecho.
