Periodontitis and diabetes in pregnant rats: Maternal-fetal outcomes.

Aim: To evaluate the repercussions of periodontitis and diabetes association on rat pregnancy and newborns. Methods: Diabetes was induced in female Wistar rats 24 h after birth through the administration of Streptozotocin. The diabetic condition of the rats was further confirmed in adulthood. After mating, the pregnant rats were distributed into four experimental groups (n = 12 rats/group): nondiabetic and diabetic with and without periodontitis. Periodontitis was induced by a ligature inserted into the first molar on day 0 of pregnancy. Body weight, water and feed consumption were evaluated weekly, and an oral glucose tolerance test was performed on day 17 of pregnancy. On day 21 of pregnancy, the animals were anesthetized and killed for organ removal. The hemimandibles were collected to analyze alveolar bone loss. Immunological and biochemical parameters were evaluated in the maternal blood samples, and reproductive performance was analyzed. The newborns were weighed, and anomalies evaluated. Results: The group with diabetes and periodontitis had a greater degree of alveolar bone loss, along with higher relative pancreatic weight, blood glucose levels, triglyceride and inflammatory cytokine levels, hepatic transaminase activity, and embryonic losses. In addition, these newborns had increased body weight, placental weight, a greater number of ossification centers, and a higher rate of visceral and skeletal anomalies. Conclusion: The combination of maternal diabetes and periodontitis negatively impacts maternal parameters and fetal development. The findings reinforce the importance of maintaining maternal oral health to ensure the general health of the offspring, especially in cases where diabetes is present.

Impact of Production Systems on the Levels of Vitamin E, ß-Carotene, and Cholesterol in the Liver of Cattle Raised in the Eastern Amazon.

The nutritional composition of bovine liver, particularly in terms of vitamins E, ß-carotene, and cholesterol concentration, is significantly influenced by the cattle-rearing system and diet. This study aimed to elucidate the impact of four predominant cattle-rearing systems in the Eastern Amazon region on the vitamin E, ß-carotene content, and cholesterol levels in bovine liver during the rainy season. Liver-tissue samples were collected from 48 cattle, with twelve specimens representing each rearing system. The systems encompassed two native pastures located in flood-prone areas, cultivated pastures on upland terrain and a confinement-rearing system. Our findings indicate that, when considering all rearing systems collectively, there were no significant differences in the levels of vitamins and cholesterol in the liver tissues (p > 0.05). However, a marked disparity in cholesterol levels emerged when comparing intensive rearing systems to extensive ones, with the former demonstrating notably higher concentrations (p = 0.01). Additionally, the intensive rearing system was associated with elevated levels of ß-carotene (p < 0.01), α-tocopherol (p = 0.01), and ß-tocopherol (p = 0.01) relative to the extensive systems. No significant variations were observed amongst the different extensive systems (p > 0.05). These results suggest that, while all rearing systems yielded liver tissues with typical concentrations of vitamins and cholesterol, the intensive rearing system led to a higher accumulation of certain vitamin compounds. This study highlights the substantial nutritional implications of different cattle-rearing systems in the Eastern Amazon and provides valuable insights for developing dietary strategies to optimize the nutritional quality of bovine liver. Therefore, the generated results are groundbreaking in the Eastern Amazon, Brazil, and inspire the development of new research projects to address other demands in this field and achieve additional outcomes.

Referred pain is associated with greater odontogenic spontaneous pain and a heightened pain sensitivity in patients with symptomatic irreversible pulpitis.

BACKGROUND: Symptomatic irreversible pulpitis often results in heightened reactions to thermal stimuli such as pain evoked by a cold stimulus, and spontaneous odontogenic pain (unprovoked pain). OBJECTIVE: This study primarily compared the clinical manifestations of odontogenic spontaneous pain and pain provoked by cold stimulus specifically focusing on their sensory discriminative characteristics (intensity, duration and quality) between symptomatic irreversible pulpitis patients with and without referred pain. METHODS: Twenty-three patients with symptomatic irreversible pulpitis with referred pain and 12 patients without referred pain were included in this cross-sectional study. The following outcomes were assessed: odontogenic spontaneous pain and its descriptors; pain evoked by cold stimulus and qualitative sensory testing before and after local anaesthesia; referred pain location; use of analgesic medication; complementary anaesthesia efficacy. T-test, chi-squared and McNemar tests were applied to the data (p < .50). RESULTS: Patients with referred pain presented a greater odontogenic pain intensity (p < .05) when considered the average of the last 24 h. These patients also showed higher pain rating and pain descriptors (p < .05). Intensity and duration of the pain evoked by cold stimulus in the non-affected contralateral tooth at baseline were higher for patients with referred pain (p < .05). CONCLUSION: Symptomatic irreversible pulpitis patients with referred pain present greater odontogenic spontaneous pain and a heightened pain sensitivity. Therefore, patients with referred pain seem more complex from a pain severity perspective, supporting the clinical utility of discriminating symptomatic irreversible pulpitis with and without referred pain.

Impact of rearing systems in the Eastern Amazon on cholesterol, ß-carotene and vitamin E homologues in steer.

Introduction: The quality of meat, with a focus on compounds important for human health, is directly related to the rearing systems in which the animals are produced. The search for a balanced diet, with an emphasis on low cholesterol and adequate levels of vitamins, aligns with society's emphasis on healthy eating, directly correlated with the importance of the offer made by producers for the cattle's diet. Objective and methodology: The objective was to verify the impact of different rearing systems, in the Eastern Amazon, during the rainy season, on the concentrations of vitamins (A, E) and cholesterol in the muscle (Longissimus lumborum) of crossbred Nelore cattle, castrated, aged between 24 and 36 months, and weighing between 410 and 628 kg. Twelve animals, from each of the three pasture rearing systems: native pasture in flooded areas of Monte Alegre; native pasture in a flooded area of Santa Cruz do Arari; and pasture cultivated on dry land in São Miguel do Guamá, all located in Pará, Brazil-were sampled in commercial slaughterhouses. Results: A notable influence was observed in the concentrations of ß-carotene (p < 0.01), α-Tocopherol (p = 0.02), ß-Tocopherol (p < 0.01) and the combined sum of ß-Tocotrienol and γ-Tocopherol (p < 0.01), as well as δ-Tocopherol (p < 0.01) when contrasting extensive with intensive systems (confinement). However, there was a difference in the content of vitamins and cholesterol between the isolated extensive systems, or between the four rearing systems (p > 0.05). Extensive systems, mainly in Monte Alegre, demonstrated greater amounts of α-Tocopherol and δ-Tocopherol. Conclusion: On the other hand, the intensive system exhibited higher levels of other investigated compounds, clarifying the nutritional variations generated by different livestock rearing practices in the region. Therefore, the results obtained are innovative in the Eastern Amazon, Brazil, in addition to inspiring the development of new research to meet other demands in this field, and achieve additional results, such as determining which meat, coming from cattle in production systems in the country, presents the better compositional quality of vitamins and lipids.

Association between Self-Perception of Chewing, Chewing Behavior, and the Presence of Gastrointestinal Symptoms in Candidates for Bariatric Surgery.

Given the changes in the digestive tract post-bariatric surgery, adapting to a new pattern of eating behavior becomes crucial, with special attention to the specifics of chewing mechanics. This study aimed to investigate the association between self-perception of chewing, chewing behavior, and the presence of gastrointestinal symptoms in preoperative patients undergoing bariatric surgery. Sixty adult candidates for bariatric surgery at a public hospital in Belém (Brazil) were analyzed. Participants predominantly exhibited unilateral chewing patterns (91.6%), a fast chewing rhythm (73.3%), a large food bolus (80%), liquid intake during meals (36.7%), and 41.7% reported that chewing could cause some issue. Significant associations were found between the perception of causing problems and chewing scarcity (p = 0.006), diarrhea (p = 0.004), absence of slow chewing (p = 0.048), and frequent cutting of food with front teeth (p = 0.034). These findings reveal a relationship between the perception of chewing problems and chewing scarcity, presence of diarrhea, and fast chewing.

Platelet-Derived Microvesicles Contribute to the Pathophysiogenesis of Human Cutaneous Leishmaniasis: A Nano-Flow Cytometric Approach in Plasma Samples from Patients before and under Antimonial Treatment.

Cutaneous leishmaniasis is a neglected tropical disease caused, in Brazil, mainly by Leishmania braziliensis, which is a protozoan transmitted during the blood feeding of infected female sandflies. To control leishmaniasis, the participation of CD4+ Th1 cells together with macrophages, neutrophils, and other peripheral blood cells, including platelets, is necessary. These anuclear fragments, when activated, produce microvesicles (MVs) that can reach locations outside the blood, carrying molecules responsible for activating pro-inflammatory responses and antigen presentation. Using flow cytometry, this current study evaluated the frequency and concentration of platelet-derived MVs (pMVs) in plasma samples obtained from patients in the acute phase and undergoing treatment, as well as from healthy volunteers. Our results revealed a higher frequency and concentration of pMVs in the plasma of patients with acute CL when compared to all other groups studied. These results highlight the impact of pMVs in modulating the immune response of CL patients, correlating their higher concentrations and frequencies in CL-patient plasmas, with the acute inflammatory status of the disease and their reduction with beneficial results of systemic treatment with antimony. This knowledge is essential to define potential treatment protocols, as well as highlight pMVs as biomarkers for the different clinical stages of CL.

Chenopodium Ambrosioides Linn Mitigates Bone Loss in Rats with Periodontitis.

Statement of the Problem: Periodontitis is an inflammatory disease that causes bone loss. Some patients do not respond well to the classic treatment and need therapies that minimize bone loss, the main sequel of the disease. Chenopodium ambrosioides L. has stood out due to its anti-inflammatory and anti-oxidative activities. However, no study has yet investigated its effect on periodontitis. Purpose: This study aimed to evaluate the bone protective effect of Chenopodium ambrosioides L. (CAL) extract on ligature-induced periodontitis model in rats. Materials and Method: For this, a pre-clinical assay was performed, using male Wistar rats divided into 3 groups: Naive (N) (n=6), not submitted to any procedure; Saline (SAL) (n=6), submitted to ligature-induced periodontitis and receiving 2 ml/kg of 0.9% saline solution; and CAL extract, which was subdivided into 3 subgroups (n=6/subgroup) receiving the CAL at 3 (CAL3), 10 (CAL10) or 30 mg/kg (CAL30). All agents were given, by oral gavage, 30 min before periodontitis induction and daily until euthanasia (11th day). By then, maxillae were removed for macroscopic, histological, and histometric analyses. Kidneys, liver, and stomach were collected to evaluate the safety of CAL extract. High-performance liquid chromatography (HPLC) assay was used to investigate the flavonoid content in the extract. Results: Chenopodium ambrosioides L. extract at 30mg/kg showed a reduction by 58% in bone loss marked by an increase (+35%) in the number of osteoblasts and a reduction (-51%) on the number of osteoclasts (p< 0.05). No significant alteration in the liver, kidney, or stomach was seen. Rutin was the main flavonoid found. Conclusion: In summary, it was observed that Chenopodium ambrosioides L. extract has shown important anti-inflammatory and bone anabolic and anti-resorptive properties without causing toxicity in the main organs. Rutin, as the main flavonoid of the extract, seems to be responsible for the beneficial effect of this agent.

Assessing the Clinical Impact of the SARS-CoV-2 Gamma Variant on Intensive Care Unit Admissions: Insights from a Reference Hospital in Northeastern Brazil.

The global challenge posed by the prolonged COVID-19 pandemic underscores the critical need for ongoing genomic surveillance to identify emerging variants and formulate effective public health strategies. This retrospective observational study, conducted in a reference hospital in Northeast Brazil and comprising 2116 cases, employed PCR genotyping together with epidemiological data to elucidate the impact of the Gamma variant during its emergence, revealing distinct patterns in hospitalization rates, severity of illness, and outcomes. The study emphasizes the challenges posed by the variant, particularly an increased tendency for ICU admissions and respiratory support, especially among adults aged 18 to 59 without comorbidities. Laboratory analyses further demonstrate elevated inflammatory, coagulation, and hepatic markers in the Gamma variant cohort, suggesting a more severe systemic response. Despite limitations, including a retrospective approach and single-institution data, the study underscores the importance of ongoing genomic surveillance. Overall, this research contributes valuable insights into the impact of the Gamma variant on COVID-19 dynamics, advocating for continued research and surveillance to inform effective public health strategies regarding evolving viral variants.

SARS-CoV-2 and dialysis: humoral response, clinical and laboratory impacts before vaccination.

BACKGROUND: Patients with kidney disease on Hemodialysis (HD) are susceptible to Coronavirus Disease (COVID-19) due to multiple risk factors. AIM: This study aims to report the prevalence of antibodies against SARS-CoV-2 among patients on hemodialysis before vaccination in Brazil and to compare with clinical, demographic, and laboratory data. METHODS: Blood samples from 398 Chronic Kidney Disease (CKD) patients treated in three different private institutions in Rio de Janeiro State, Brazil were submitted to the total anti-SARS-CoV-2 testing. Kidney, liver, and hematological markers were also determined. Respiratory samples were tested by real-time PCR for SARS-CoV-2 RNA and positive samples were subjected to high-throughput sequencing on the MinION device. RESULTS: Overall, anti-SARS-CoV-2 prevalence was 54.5 % (217/398) and two individuals had SARS-CoV-2 RNA with variant B.1.1. High anti-SARS-CoV-2 seroprevalence was found in male gender and those with hospital admission in the last 3-months before the inclusion in the study. Lower red blood cell count was observed in the anti-SARS-CoV-2 seropositive group. High levels of anti-SARS-CoV-2 were found in those who reported symptoms, had low levels of eosinophils and low hematocrit, and who practiced physical activity. CONCLUSION: High prevalence of anti-SARS-CoV-2 was found in CKD patients before the universal immunization in Brazil suggesting that dialysis patients were highly exposed to SARS-CoV-2.

Smartphone-based inertial measurements during Chester step test as a predictor of length of hospital stay in abdominopelvic cancer postoperative period: a prospective cohort study.

BACKGROUND: Objective assessment of pre-operative functional capacity in cancer patients using the smartphone gyroscope during the Chester step (CST) test may allow greater sensitivity of test results. This study has investigated whether the CST is a postoperative hospital permanence predictor in cancer patients undergoing abdominopelvic surgery through work, VO2MAX and gyroscopic movement analysis. METHODS: Prospective, quantitative, descriptive and inferential observational cohort study. Fifty-one patients were evaluated using CST in conjunction with a smartphone gyroscope. Multivariate linear regression analysis was used to examine the predictive value of the CST. RESULTS: The duration of hospital permanence 30 days after surgery was longer when patients who performed stage 1 showed lower RMS amplitude and higher peak power. The work increased as the test progressed in stage 3. High VO2MAX seemed to be a predictor of hospital permanence in those who completed levels 3 and 4 of the test. CONCLUSION: The use of the gyroscope was more accurate in detecting mobility changes, which predicted a less favorable result for those who met at level 1 of the CST. VO2MAX was a predictor of prolonged hospitalization from level 3 of the test. The work was less accurate to determine the patient's true functional capacity.

Investigation of occupational risk factors for the development of non-Hodgkin's lymphoma in adults: A hospital-based case-control study.

Non-Hodgkin's Lymphoma (NHL) is a malignancy of the lymphoid lineage of the hematopoietic system has worldwide, especially in developed countries. Better diagnostic and recording techniques, longer life expectancy, and greater exposure to risk factors are hypotheses for this growing incidence curve. Occupational exposures to chemical, biological, and physical agents have also been associated with NHL development, but the results are still controversial. We have investigated the occupational and lifestyle case-control study design with 214 adult patients and 452 population controls. Socio-demographic, clinical, and occupational exposure data were obtained through individual interviews with a standardized questionnaire. Clinical, laboratory, and histopathological data were obtained through medical records. Risk of NHL (any subtype), B-cell lymphoma, DLBCL, Follicular lymphoma and T-cell lymphoma was elevated among the those who had ever been exposed to any solvents, hydrocarbon solvents, pesticides, meat and meat products, and sunlight and tended to increase by years of exposure. A significant upward trend with years of exposure was detected for any solvents and hydrocarbon solvents (NHL (any subtype) p-value for trend<0.001), B-cell lymphoma (p-value for trend<0.001), and T-cell lymphoma (p-value for trend<0.023), pesticides (NHL (any subtype), p for trend<0.001) and T-cell lymphoma (p for trend<0.002), meat and meat products (NHL (any subtype) (p for trend<0.001) and DLBCL (p for trend<0.001), and sunlight (B-cell lymphoma (p for trend<0.001). The results of this study agree line with other international studies, can be extrapolated to other countries that have the same socio-demographic and occupational characteristics as Brazil and support strategies for surveillance and control of work-related cancer.

Displasia ectodérmica: relato de caso de reabilitação estético-funcional / Ectodermal dysplasia: a case report of aesthetic-functional rehabilitation

Objetivo: Descrever o caso clínico de um paciente portador de displasia ectodérmica (DE), discutindo as principais características desta síndrome e o tratamento odontológico proposto. Relato do caso: Paciente do sexo masculino com 6 anos de idade procurou atendimento com a queixa de "ter dificuldades na alimentação e sofrer bullying na escola devido à falta de alguns dentes". Na anamnese o responsável apresentou diagnóstico médico de DE. Ao exame intrabucal observou-se microdontia dos caninos superiores e incisivo central superior esquerdo decíduos, e ausência dos demais elementos dentários. Como proposta de tratamento foram realizadas as reanatomizações com resina composta dos três dentes decíduos presentes em boca e confecção de prótese parcial removível (PPR) superior e prótese total (PT) inferiorpara substituir os dentes faltantes, trazendo a reabilitação estética e protética do paciente, bem como a melhora da sua autoestima e bem-estar. Discussão: A DE é uma doença hereditária de origem embrionária que acomete estruturas derivadas do ectoderma, como os cabelos, unhas, pele, glândulas e dentes. Manifestações dentárias importantes, como agenesia, podem ser verificadas nos pacientes portadores dessa síndrome. Conclusão: Diante disso, é extremamente importante que o cirurgião-dentista saiba identificar as principais características dessa síndrome, já que em muitos casos o mesmo é o primeiro profissional a ser procurado pelo paciente ou sua família. Uma vez estabelecido o diagnóstico, os pacientes acometidos devem receber uma abordagem multiprofissional para o tratamento dessa condição, a fim de promover o bem-estar físico, emocional e aumentar a qualidade de vida dos mesmos.

Aim: describe aclinical case of a patient with ectodermal dysplasia (ED), discussing the main characteristics of this syndrome and the proposed dental treatment. Case report: A 6-year-old male patient sought care complaining of "having difficulties in eating and being bullied at school due to missing some teeth". In the anamnesis, the person responsible presented a medical diagnosis of ED. The intraoral examination showed microdontia of the maxillary canines and deciduous maxillary left central incisor, and absence of other dental elements. As treatment proposals, reanatomizations were carried out with composite resin of the three deciduous teeth present in the mouth and construction of an upper removable partial denture (PPR) and a lower total denture (PT) to replace the missing teeth, bringing the aesthetic and prosthetic rehabilitation of the patient, as well as improving their self-esteem and well-being. Discussion:EDis a hereditary disease of embryonic origin that affects structures derived from the ectoderm, such as hair, nails, skin, glands and teeth. Important dental manifestations, such as agenesis, can be seen in patients with this syndrome. Conclusion:In view of this, it is extremely important that the dentist knows how to identify the main characteristics of this syndrome, since in many cases he is the first professional to be sought by the patient or his family. Once the diagnosis is established, affected patients should receive a multi-professionalapproach to the treatment of this condition, in order to promote physical and emotional well-being and increase their quality of life.

Mediating effect of eating pattern on the relationship between television exposure and caries in children.

Behavioral characteristics may also take part in the etiology of dental caries. Sedentary behavior, especially watching television, is associated with increased intake of foods high in fat or free sugar, which could influence the occurrence of dental caries. The aim of this study was to assess the mediating effect of eating pattern on the relationship between television exposure time and the presence of dental caries in children. A cross-sectional study was conducted with a representative sample of 580 parent-child dyads with children aged 7 to 8 years in 20 public schools in Pelotas, Brazil. Parents or legal guardians were interviewed and provided information on demographic/socioeconomic data, children's daily television exposure time, and answered the Biological Rhythms Interview for Assessment in Neuropsychiatry for Kids (BRIAN-K-eating pattern domain). Caries was evaluated through clinical examination. The mediating effect of eating pattern on the relationship between television exposure and presence of dental caries was estimated using the parametric g-formula. Prevalence of dental caries was 63%, and 22% of children watched TV 4 or more hours per day. Television exposure had no direct effect on the dental caries experience [odds ratio (OR): 1.05 (95% confidence interval (95%CI): 0.92-1.19)]. Nevertheless, difficulty maintaining regular eating pattern mediated the natural indirect effect of television exposure time (≥ 4 hours/day) on dental caries experience [OR: 1.07 (95%CI): 1.01-1.14)]. The results of this study confirm the indirect pathway between television viewing and dental caries and the role of disordered eating patterns in this association.

Agreement between schoolchildren and their parents on rating the child's oral health-related quality of life.

The perceptions of parents/caregivers regarding their children's oral health can influence the standard of care and decision-making regarding oral health. The children's perspective on their own oral health-related quality of life (OHRQoL) may differ from the parents/caregivers' views. This cross-sectional study aimed to analyze the agreement between the perceptions of parents/caregivers and schoolchildren regarding OHRQoL. It was conducted with a sample of children between 8 and 11 years old and their parents/caregivers from Pelotas. Children answered the Child Perceptions Questionnaire 8-10 (CPQ), and parents/caregivers answered the short form of the Parental-Caregiver Perceptions Questionnaire (P-CPQ). Socioeconomic data were also collected. Children's dental caries, traumatic dental injuries, and malocclusions were examined. The Spearman's correlation test was performed. A total of 119 parents/caregivers-children pairs were included. There was an agreement between the total scores of parents/caregivers and children (0.2770; p = 0.003), in the oral symptoms (0.1907; p = 0.038), and functional limitations (0.2233; p=0.015) domains. The Bland-Altman graph showed an agreement between children's and parents/caregivers' OHRQoL total score, but there was an underestimation of approximately two points in the parents/caregivers' perception compared to the children's score. There was an agreement between the reports of parents/caregivers and children regarding children's OHRQoL.

Relação entre a condição bucal de gestantes internadas e desfechos adversos na gestação / Relationship between the oral condition of hospitalized pregnant women and adverse pregnancy outcomes

Objetivo: avaliar se a condição bucal favoreceu a presença de desfechos adversos da gestação (DAG) em mulheres internadas e acompanhadas em um hospital escola. Métodos: um estudo de coorte retrospectiva com mulheres grávidas que foram internadas entre setembro de 2019 e início de março de 2020 e que continuaram o acompanhamento obstétrico. Resultados: Das 65 gestantes que seguiram acompanhamento, 27 (41,5%) dos bebês nasceram pré-termo e 20 (30,8%) com baixo peso, sendo que as duas condições estavam presentes em 15 crianças (23,1%), sendo significantemente relacionadas com a menor semana gestacional na internação. Ao relacionar diferentes fatores com o desfecho pré-termo, houve diferença significante em gestantes com a ocupação "do lar" e com o tempo de internação igual ou maior que 10 dias e com a presença de baixo peso ao nascer. Não foi observada relação dos dados avaliados da condição bucal das gestantes na internação com o parto pré-termo. Conclusões: Gestantes que necessitam de internação hospitalar durante a gravidez, independente da condição bucal, aumentam a possibilidade de apresentarem DAG, sendo fundamental a realização do correto acompanhamento pré-natal.(AU)

Objective: to assess whether the oral condition favored the presence of adverse effects during pregnancy in pregnant women hospitalized and followed up at a teaching hospital. Methods: a retrospective cohort study with mothers who were hospitalized during pregnancy between September 2019 and early March 2020 and who continued obstetric follow-up. Results: 83 pregnant women were interviewed and 65 were followed up Of the 65 pregnant women who followed up, 27 (41.5%) of the babies were born preterm and 20 (30.8%) with low birth weight, and both conditions were present in 15 children (23.1%), being significantly related to the shortest gestational week at admission. When relating different factors with the preterm outcome, there was a significant difference in pregnant women with the occupation "housewife" and with the length of hospital stay equal to or greater than 10 days and with the presence of low birth weight. There was no relationship between the evaluated data on the oral condition of pregnant women during hospitalization and preterm delivery. Conclusions: Pregnant women who require hospitalization during pregnancy, regardless of oral condition, increase the possibility of having negative pregnancy outcomes, and correct prenatal care is essential. (AU)

A internação da gestante pode afetar a condição bucal do filho no terceiro ano de vida? / Can a pregnant woman's hospitalization affect the child's oral condition in the third year of life?

Objetivo: Avaliar se a hospitalização na gestação pode influenciar na condição bucal do filho no terceiro ano de vida. Métodos: Estudo longitudinal com bebês de gestantes internadas e acompanhadas no setor da Obstetrícia de um Hospital Escola em Pelotas, RS, Brasil. Os dados referentes a hospitalização e ao parto foram coletados do prontuário hospitalar e no terceiro de vida do filho (a) de um questionário aplicado a mãe e do exame bucal da criança. Cada agravo bucal foi avaliado com critérios específicos, por uma examinadora calibrada e analisado no programa IBM SPSS Statistics com 5% de nível de significância. Resultados: Participaram 20 díades mãe-filho (a). Alterações da oclusão acometeram 95% das crianças, sendo a mordida aberta anterior (MAA) a principal. Ainda, 25% das crianças apresentaram opacidades demarcas e/ou hipoplasia do esmalte, sendo significativamente maior em filhos de mães mais jovens e 20% tinham cárie da primeira infância (CPI), estando relacionada à ausência de creme dental fluoretado e à qualidade da higiene bucal. Conclusão: O reflexo mais evidente da hospitalização na gestação na saúde bucal no terceiro ano de vida do filho (a) foi a oclusão alterada, especialmente a MAA.(AU)

Methods: Longitudinal study with babies of pregnant women hospitalized and followed up in the Obstetrics sector of a Teaching Hospital in Pelotas, RS, Brazil. Data referring to hospitalization and childbirth were collected from the hospital records and in the child's third of life through a questionnaire applied to the mother and the child's oral examination. Each oral condition was evaluated with specific criteria, by a calibrated examiner and analyzed in the IBM SPSS Statistics program with a 5% minimum significance level. Results: 20 mother-child participated. Occlusion alterations affected 95% of the children, with anterior open bite (AOB) being the main. Still, 25% of the children had opacities and/or enamel hypoplasia, which was significantly higher in children of younger mothers, and 20% had early childhood caries, which is related to the absence of fluoride toothpaste and the quality of oral hygiene. Conclusion: The clearest reflection of hospitalization during pregnancy on oral health in the third year of the child's life was altered occlusion, especially the AOB.(AU)

Circulation of HDV Genotypes in Brazil: Identification of a Putative Novel HDV-8 Subgenotype.

Hepatitis D virus (HDV) is classified into 8 genotypes (1 to 8) and several subgenotypes. In Brazil, HDV-3 and HDV-1 predominate; however, most of the diagnosis efforts and molecular studies are directed to the area of endemicity of the Amazon Basin. Here, we determined the molecular epidemiological profile of circulating HDV in Brazilian HBsAg-positive patients between 2013 and 2015 in areas of endemicity and non-areas of endemicity. From 38 anti-HDV-positive individuals, 13 (34.2%) had detectable HDV-RNA and 11 (28.9%) were successfully sequenced. Partial HDAg (~320 nt) sequencing followed by phylogenetic analysis with reference sequences resulted in the identification of HDV-3 (9/11; 81.8%), HDV-5 (1/11; 9.1%), and HDV-8 (1/11; 9.1%). Most HDV-3 samples (8/9; 88.9%) were found in the endemic North region, while one was found in Central-West Brazil, a non-area of endemicity. HDV-5 and 8, genotypes native from African countries, were found in São Paulo, a cosmopolitan city from Southeast Brazil with a high circulation of immigrants. Phylogenetic analysis of HDV-8 strains indicated that the sample determined in our study, along with previously reported sequences from Brazil, formed a highly supported monophyletic clade, likely representing a putative novel HDV-8 subgenotype. IMPORTANCE Considered a neglected pathogen until the last 2 decades, an increase in the availability of genetic data of hepatitis D virus (HDV) strains around the world has been noticed recently, resulting in the proposition of different classifications. Our study aimed to determine the molecular epidemiological profile of HDV isolates circulating in areas of endemicity and non-areas of endemicity in Brazil. Based on the analyzed fragment, HDV-8 sequences clustered out of the clades formed by subgenotypes 8a and 8b might suggest the identification of a novel subgenotype, putatively designated subgenotype 8c. Our findings demonstrate the importance of continuous epidemiological surveillance to map HDV spread pathways and the introduction of imported variants. It also reinforces that as the amount of HDV genomes generated and reported increases, we will have changes in viral classification and, consequently, in our understanding of the dynamics of variability of this viral agent.
