Standardization of Dental Vulnerability Scale scores (EVO-BR).

BACKGROUND: Dental Vulnerability Scale (EVO-BR) is an instrument developed to help identifying oral health-vulnerable individuals. This scale comprises 15 items distributed into 4 dimensions. It is the first instrument with the potential to guide clinical and managerial decisions in the oral health field. The aim is to validate a score to enable using EVO-BR in Primary Health Care (PHC). METHOD: The investigated sample included PHC users in five Brazilian regions. Data were collected at two different stages: in 2019 (São Paulo) and in 2022 (Minas Gerais, Mato Grosso, Roraima, Pernambuco e Paraná). Exploratory descriptive study of this scale scores was carried out to create classification ranges. Subsequently, discriminant analysis was performed to assess the accuracy of the established classification. Boosting regression was carried out to check items' weight for the instrument score. RESULTS: EVO-BR score ranged from 0 (highest vulnerability) to 15 (lowest vulnerability). Four (4) classification configurations were tested. Score equal to 12 points was the one presenting the best classification of the assessed individuals (100% were correctly classified). Boosting regression has evidenced that items 1 and 2 (Overall health domain) and 14 and 15 (Health Services domain) had the strongest influence on this instrument's score. CONCLUSION: The process to standardize the EVO-BR score and, consequently, to develop assessment ranges, is an important step in the fight against health inequalities, since it provides a tool to help planning actions and interventions aimed at meeting specific needs of the population in the Primary Health Care context.

Home caregiver strategies for feeding older adults with dysphagia after dehospitalization.

OBJECTIVE: To understand caregivers' strategies for offering food to older adults with oropharyngeal dysphagia after dehospitalization. METHOD: Qualitative research carried out with caregivers of older adults with oropharyngeal dysphagia, who were discharged after hospitalization at a university hospital in Bahia. Data collection was carried out between January and February 2023 through a semi-structured interview, whose data were organized based on content analysis and analyzed with the help of IRaMuTeQ software. RESULTS: Three categories emerged: Caregivers' strategies for safely offering food to older adults with dysphagia; Caregiver strategies for oral hygiene for older adults; Recognition of continuity of speech therapy after dehospitalization. CONCLUSION: Caregivers' strategies for offering food to older adults with oropharyngeal dysphagia were supported by tacit knowledge and effective care in the hospital-home transition.

Validation of the internal structure of the Brazilian Dental Vulnerability Scale.

OBJECTIVE: This study aimed to evaluate evidence of validity of internal structure of the Brazilian Dental Vulnerability Scale (EVO-BR) when applied in Brazil. METHODS: This is a psychometric study that seeks to validate a scale elaborated by evidence of internal structure. Data collection was conducted in 18 basic health units that implement the Brazilian Healthcare Planning (PAS) methodology, across the five regions of Brazil. The initial version of the EVO-BR contained 41 items that measured dental vulnerability and was applied to users of the Brazilian Unified Health System (SUS) aged 18 years or older who were in basic health units for consultation with higher education professionals. To evaluate the evidence, the following statistical analyses were performed: exploratory factor analysis, confirmatory factor analysis, and network analysis. RESULTS: A total of 1,753 users participated in the study. To adjust the sample, we considered the factorability obtained from Kaiser-Meyer-Olkin (KMO) test = 0.65, Bartlett sphericity test = 8019.7, and a matrix determinant of 0.008. The initial parallel analysis indicated a four-dimensional model and had the items adjusted according to factor loading (ranging from 0.38 to 0.99), common factors (0.13 to 0.89), and Pratt's measure, until the model presented congruence in the statistical and interpretative principles simultaneously. The final model contained 15 items, maintaining the four dimensions indicated by the parallel analysis, and held an explained variance of 68.56%. CONCLUSIONS: The EVO-BR is a validated scale to measure dental vulnerability and, thus, can contribute to the organization of access to the oral health team in primary health care (PHC) by stratifying the population, as recommended in the Brazilian Healthcare Planning.

Idosos Domiciliados: Saúde Geral x Higiene Bucal / Elderly People Living at Home: General Health x Oral Hygiene

O Serviço Integrado da Assistência Domiciliar (SIAD) foi criado a fim de prestar atendimento integral domiciliar a idosos que apresentam incapacidade de se locomover para as unidades de atendimento de saúde da Marinha do Brasil (MB). Com a finalidade de avaliar o perfil de saúde geral e de higiene dental desses pacientes, foi realizado um estudo transversal, quantitativo e descritivo, no qual foram incluídos idosos com 60 anos ou mais, assistidos entre fevereiro de 2017 a dezembro de 2022. Pode-se observar que a maioria dos idosos eram longevos, com média de idade de 82,52 anos (±8,66), mulheres (63,52%) e possuíam dependência total para realizar atividades básicas de vida diária (88,9%). Conclui-se que a síndrome demencial foi o diagnóstico principal mais encontrado (44,3%), a maioria possuía comorbidade associada (71,9%), sendo a Hipertensão Arterial Sistêmica (59,2%) e o Diabetes Mellitus (28,9%) as mais recorrentes. Foi encontrada uma elevada prevalência de idosos domiciliados com higiene bucal insatisfatória (34,7%) ou irregular (57,2%). No entanto, não houve associação entre higiene dental, comorbidades e grau de dependência. Assim sendo, é imprescindível que os idosos domiciliados recebam orientações e sejam submetidos a um acompanhamento rigoroso e constante, juntamente com seus cuidadores, a fim de promover a melhoria da higiene oral desses pacientes.

The Integrated Home Assistance Service (IHAS) was created to provide integral home care for elderly people who are unable to go to the health care units of the Brazilian Navy. A cross-sectional, quantitative, and descriptive study was carried out to evaluate the general health and dental hygiene profile of these patients. The study included elderly people aged 60 years or older who were assisted between February 2017 and December 2022. Most of them were long-lived, with a mean age of 82.52 (±8.66) years, women (63.52%) and totally dependent on performing basic activities of daily living (88.9%). The most common diagnosis among them was dementia syndrome, accounting for 44.3% of cases. Additionally, a large portion of the elderly had associated comorbidities (71.9%), with Systemic Arterial Hypertension (59.2%) and Diabetes Mellitus (28.9%) as the most recurrent conditions. The study found a high prevalence of elderly with unsatisfactory (34.7%) or irregular (57.2%) oral hygiene. Nevertheless, there was no significant association between dental hygiene and comorbidities or the degree of dependence. Therefore, it is imperative that elderly people living at home receive guidance and undergo meticulous and ongoing monitoring, in conjunction with their caregivers to promote improvements in the oral hygiene of these patients.

Impact of Long-Term Cyclamate and Saccharin Consumption on Biochemical Parameters in Healthy Individuals and Type 2 Diabetes Mellitus Patients.

BACKGROUND: Previous studies on saccharin and cyclamate were either limited to experimental animals or lacked evaluation of their long-term consumption effects in humans. OBJECTIVES: This study evaluated the effect of chronic consumption of saccharin and cyclamate on biochemical parameters in healthy individuals and patients with type 2 diabetes mellitus. MATERIAL AND METHODS: Healthy and diabetic individuals were classified into two groups based on whether they consumed sweeteners or not. The participants were classified according to the amount of sweetener consumed per day and duration of consumption. Serum catalase activity, peroxynitrite, ceruloplasmin, and malondialdehyde concentrations were determined. Glycated hemoglobin, fasting glucose, creatinine, alanine transaminase, and lipid profile were also evaluated. The results suggest that saccharin and cyclamate increased HbA1C (+11.16%), MDA (+52.38%), TG (+16.74%), LDL (+13.39%), and TC/HDL (+13.11%) in healthy volunteers. Diabetic patients consuming sweeteners showed increased FSG (+17.51%), ceruloplasmin (+13.17%), and MDA (+8.92%). Diabetic patients showed a positive correlation between the number of tablets consumed per day with FSG and serum creatinine. A positive correlation was found between the duration of sweetener consumption and FSG as well as TG. CONCLUSION: Consumption of saccharin and cyclamate affected biochemical parameters related to metabolic functions in a time and dose-dependent manner and appear to increase oxidative stress in healthy and diabetic type 2 patients.

Antifungal effect of Arnica montana and Hamamelis virginiana against Candida species

Objetivo ­ Avaliar a atividade antifúngica dos extratos glicólicos de Arnica montana e Hamamelis virginiana contra cepas de Candida spp. A candidíase é uma infecção fúngica comum, portanto, a pesquisa de novos agentes antifúngicos tem sido um alvo interessante. Várias plantas apresentaram atividades biológicas e, portanto, podem ser fontes promissoras de produtos naturais com atividades an-tifúngicas. Métodos ­ As atividades antifúngicas dos extratos glicólicos foram avaliadas por meio da determinação da concentração inibitória mínima (CIM) de acordo com o protocolo M27-S3 do Clinical and Laboratory Standards Institute (2008). Resultados ­ O ex-trato glicólico de A. montana apresentou a atividade antifúngica mais forte contra C. tropicalis, com concentração inibitória mínima (CIM) de 10% v/v e concentração fungicida mínima (MFC) de 80% v/v, seguido por C. krusei e C. glabrata, com valores de MIC e MFC de 20% v/v. Além disso, avaliamos a toxicidade dos dois extratos glicólicos no modelo Galleria mellonella usando as curvas de sobre-vivência de larvas tratadas com os extratos. Nossos resultados demonstraram que os extratos glicólicos de A. montana e H. virginiana não exibiram toxicidade contra larvas de G. mellonella e demonstraram atividade antifúngica contra espécies de Candida spp. Con-clusão ­ Assim, ambos os extratos são candidatos promissores para o desenvolvimento de novos agentes antifúngicos.

Objective ­ To evaluate the antifungal activity of Arnica montana and Hamamelis virginiana glycolic extracts against Candida strains. Methods ­ The antifungal activities of glycolic extracts were investigated by determination of the minimum inhibitory concentration (MIC) according to protocol M27-S3 of Clinical and Laboratory Standards Institute (2008). Results ­ A. montana glycolic extract showed the strongest antifungal activity against C. tropicalis, with a minimum inhibitory concentration (MIC) of 10% v/v and a minimum fungicidal concentration (MFC) of 80% v/v, then C. krusei and C. glabrata, with MIC and MFC values of 20% v/v. H. virginiana glycolic extract ex-hibited stronger activity against C. albicans and C. tropicalis, with MIC and MFC values of 10% v/v, than against C. glabrata, C. krusei, and C. parapsilosis, with MIC and MFC values of 20% v/v. Moreover, we evaluated the toxicity of the two glycolic extracts in the Galleria mellonella model using the survival curves of larvae treated with the two extracts. Our results demonstrated that the glycolic extracts of A. montana and H. virginiana exhibited no toxicity against G. mellonella larvae and demonstrated antifungal activity against Candida spe-cies. Conclusion ­ Thus, both extracts are promising candidates for the development of novel antifungal agents.

Pedigree reconstruction and population structure using SNP markers in Gir cattle.

Our objective was to establish a SNPs panel for pedigree reconstruction using microarrays of different densities and evaluate the genomic relationship coefficient of the inferred pedigree, in addition to analyzing the population structure based on genomic analyses in Gir cattle. For parentage analysis and genomic relationship, 16,205 genotyped Gir animals (14,458 females and 1747 males) and 1810 common markers to the four SNP microarrays were used. For population structure analyses, including linkage disequilibrium, effective population size, and runs of homozygosity (ROH), genotypes from 21,656 animals were imputed. Likelihood ratio (LR) approach was used to reconstruct the pedigree, deepening the pedigree and showing it is well established in terms of recent information. Coefficients for each relationship category of the inferred pedigree were adequate. Linkage disequilibrium showed rapid decay. We detected a decrease in the effective population size over the last 50 generations, with the average generation interval around 9.08 years. Higher ROH-based inbreeding coefficient in a class of short ROH segments, with moderate to high values, was also detected, suggesting bottlenecks in the Gir genome. Breeding strategies to minimize inbreeding and avoid massive use of few proven sires with high genetic value are suggested to maintain genetic variability in future generations. In addition, we recommend reducing the generation interval to maximize genetic progress and increase effective population size.

Prevalence of bat viruses associated with land-use change in the Atlantic Forest, Brazil.

Introduction: Bats are critical to maintaining healthy ecosystems and many species are threatened primarily due to global habitat loss. Bats are also important hosts of a range of viruses, several of which have had significant impacts on global public health. The emergence of these viruses has been associated with land-use change and decreased host species richness. Yet, few studies have assessed how bat communities and the viruses they host alter with land-use change, particularly in highly biodiverse sites. Methods: In this study, we investigate the effects of deforestation on bat host species richness and diversity, and viral prevalence and richness across five forested sites and three nearby deforested sites in the interior Atlantic Forest of southern Brazil. Nested-PCR and qPCR were used to amplify and detect viral genetic sequence from six viral families (corona-, adeno-, herpes-, hanta-, paramyxo-, and astro-viridae) in 944 blood, saliva and rectal samples collected from 335 bats. Results: We found that deforested sites had a less diverse bat community than forested sites, but higher viral prevalence and richness after controlling for confounding factors. Viral detection was more likely in juvenile males located in deforested sites. Interestingly, we also found a significant effect of host bat species on viral prevalence indicating that viral taxa were detected more frequently in some species than others. In particular, viruses from the Coronaviridae family were detected more frequently in generalist species compared to specialist species. Discussion: Our findings suggest that deforestation may drive changes in the ecosystem which reduce bat host diversity while increasing the abundance of generalist species which host a wider range of viruses.

Ultra-processed foods consumption among children and associated socioeconomic and demographic factors.

OBJECTIVE: To evaluate the consumption of ultra-processed foods among children, and to investigate associations with socioeconomic and demographic factors. METHODS: An analytical cross-sectional study with 599 children aged 6 months to 2 years, and listed as users of Family Health Units, in a medium-size city. Mothers were approached at home by researchers and community health workers from the Family Health Units, for data collection. Two questionnaires were used: the socioeconomic and demographic questionnaire, and the form Sistema de Vigilância Alimentar e Nutricional of Ministério da Saúde do Brasil , for children aged 6 months to 2 years. Ultra-processed food consumption and socioeconomic and demographic factors were defined as dependent and independent variables, respectively. Multiple regression analysis with a significance level of 5% was used to test associations between ultra-processed food consumption and socioeconomic and demographic variables. RESULTS: Ultra-processed food consumption was associated with child age between 1 and 2 years (OR=3.89; 95%CI: 2.32-6.50 and OR=3.33; 95%CI: 2.00-5.56, respectively), number of people living in the same household (OR=1.94; 95%CI: 1.23-3.05), and recipients of government benefits (OR=1.88; 95%CI: 1.15-3.04). CONCLUSION: Ultra-processed food consumption among children undergoing complementary feeding may be influenced by socioeconomic and demographic factors.

Dental vulnerability scale in primary health care: evidence of content and structure internal validity.

BACKGROUND: Access to oral health services remains a challenge in the Brazilian healthcare system, especially in the primary health care setting, where the use of a risk stratification tool that could identify individuals with higher dental vulnerability would be extremely valuable. However, there literature on this theme is scarce, and there is no validated instrument in Brazil that is capable of measuring dental vulnerability. Hence, this psychometric study aimed at the development and evaluation of content and internal structure validity of the Dental Vulnerability Scale for Primary Health Care (PHC). METHODS: The items were developed based on a qualitative exploratory analysis. A total of 172 items were prepared and submitted to a panel of specialists, with content validity analyzed with the Content Validity Ratio (CVR), resulting in an the initial version of the instrument composed by 41 items. Internal structure validity was analyzed by Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and by applying 3 reliability indicators (Cronbach's Alpha, McDonald's Omega and Greatest Lower Bound - GBL), with a sample of 1227 individuals. RESULTS: The final configuration indicated a scale of 15 items divided into 4 dimensions (overall health, oral health, infrastructure, and healthcare services) with explained variance of 72.11%. The factor loads varied from 0.37 to 0.96. The model adjustment indices were set at × 2/df(51) = 3.23, NNFI = 0.95, CFI = 0.98, GFI = 0.96, AGFI = 0.97, RMSEA = 0.04 and RMSR = 0.03. CONCLUSION: DVS presented satisfactory evidence of validity, indicating its suitability to be used by healthcare professionals, students and managers to plan oral health actions and services at PHC.

COVID-19 pandemic impact on dentists in Latin America's epicenter: São-Paulo, Brazil.

The state of São Paulo, Brazil, where more than 94.000 dentists are currently registered, has become the epicenter of COVID-19 in Latin America. The aim of this cross-sectional study was to evaluate the impact of COVID-19 pandemic on dentists in this state. A semi-structured questionnaire was sent via e-mail to 93.280 dentists with active registration in the Dental Council of São Paulo (CROSP). The impact of COVID-19 pandemic was assessed through questions related to demographic, socioeconomic, dental practice characteristics and personal protective equipment (PPE) use. Ordinal logistic regression analysis was performed to investigate the association between all the variables (p<0.05). Over 8 days, 2113 responses were received. Only 26.52% of the sample reported a low-income reduction (from 0-10%), while the majority of dentists reported a more negative financial impact, 35.6% with a reduction of more than 50% of their monthly income. Dentists who worked in the private sector and at the capital had a greater financial impact when compared to those of the public sector and countryside of the state (p<0.05). Furthermore, about 83% reported not having received any specific training to control the transmission of coronavirus in the health area. This study provides evidence of the negative impact of the COVID-19 pandemic on the routine of dentists in the state of São Paulo, Brazil. Hopefully, this study will help dental and other health care professionals to better understand the consequences of disease in dental settings and strengthen preparedness throughout the dental health care system.

Impact of telephone monitoring on cancer patients undergoing esophagectomy and gastrectomy.

OBJECTIVE: To evaluate telephone monitoring for symptoms, quality of life, distress, admissions to the emergency center and the satisfaction of cancer patients undergoing esophagectomy and gastrectomy. METHOD: Randomized controlled study in two groups, carried out at the Cancer Institute of the State of Sao Paulo; the intervention group received telephone monitoring for four moments after the surgery, while the control group received only institutional care. RESULTS: Of the 81 patients evaluated, the domain most affected by quality of life was social relationships domain. Distress had no significant difference between groups and moments. In both groups, admissions to the emergency center were similar (p=0.539). Pain was the most reported symptom in telephone monitoring. There was statistical significance regarding patient satisfaction with monitoring (p=0.002). CONCLUSION: Telephone monitoring provided greater patient satisfaction in the intervention group, demonstrating the real impact of this process on the care of cancer patients.

Silver nanoparticles obtained from Brazilian pepper extracts with synergistic anti-microbial effect: production, characterization, hydrogel formulation, cell viability, and in vitro efficacy.

The synthesis of silver nanoparticles using plant extracts is known as a green approach, as it does not require the use of high pressure, energy, high temperature, or toxic chemicals. The approach makes use of plant extracts in a process called bioreduction, which is mediated by enzymes, proteins, amino acids, and metabolites found in bark, seed, and leaf extracts, transforming silver ions into metallic silver. This work aimed at developing silver nanoparticles (AgNPs) from Brazilian pepper, applying this green methodology. Hydroalcoholic extract of leaves of Schinus terebinthifolius Raddi was prepared and its concentration of polyphenols, tannins, and saponins quantified. The produced nanoparticles were characterized by UV-Vis spectroscopy, thermogravimetric analysis (TG), dynamic light scattering (DLS), and zeta potential (ZP). AgNPs were formulated in sodium alginate hydrogels to obtain a nano-based semi-solid formulation for skin application. The obtained silver nanoparticles of mean size between 350 and 450 nm showed no cytotoxicity against L929 mouse fibroblasts within the concentration range of 0.025 mg/mL and 10 mg/mL. Schinus terebinthifolius Raddi was found to enhance microbial inhibition against the tested strains, especially against gram-negative bacteria. Its potential use as an alternative to overcome bacterial resistance can be expected.

Aedes aegypti post-emergence transcriptome: Unveiling the molecular basis for the hematophagic and gonotrophic capacitation.

The adult females of Aedes aegypti mosquitoes are facultative hematophagous insects but they are unable to feed on blood right after pupae emergence. The maturation process that takes place during the first post-emergence days, hereafter named hematophagic and gonotrophic capacitation, comprises a set of molecular and physiological changes that prepare the females for the first gonotrophic cycle. Notwithstanding, the molecular bases underlying mosquito hematophagic and gonotrophic capacitation remain obscure. Here, we investigated the molecular and biochemical changes in adult Ae. aegypti along the first four days post-emergence, prior to a blood meal. We performed a RNA-Seq analysis of the head and body, comparing male and female gene expression time courses. A total of 811 and 203 genes were differentially expressed, respectively in the body and head, and both body parts showed early, mid, and late female-specific expression profiles. Female-specific up-regulation of genes involved in muscle development and the oxidative phosphorylation pathway were remarkable features observed in the head. Functional assessment of mitochondrial oxygen consumption in heads showed a gradual increase in respiratory capacity and ATP-linked respiration as a consequence of induced mitochondrial biogenesis and content over time. This pattern strongly suggests that boosting oxidative phosphorylation in heads is a required step towards blood sucking habit. Several salivary gland genes, proteases, and genes involved in DNA replication and repair, ribosome biogenesis, and juvenile hormone signaling were up-regulated specifically in the female body, which may reflect the gonotrophic capacitation. This comprehensive description of molecular and biochemical mechanisms of the hematophagic and gonotrophic capacitation in mosquitoes unravels potentially new targets for vector control.
