Abstract: En | Text: En | PDF: En

ABSTRACT The present research aimed to compare the HRV of people living with HIV (PLWH) with non-infected individuals in aquatic and dryland environments. Twenty participants were divided into two groups. PLWH composed the experimental group (EG), and seronegative participants composed the control group (CG). In dryland, HRV was measured in time and frequency domains, as follows: 10 minutes in rest (RES), 20 minutes of moderate and intense aerobic exercise (EXE), and 30 minutes post-exercise recovery (REC). After 72 hours, the same procedures were repeated in the aquatic environment. HRV analysis demonstrated significant differences in Mean r-r (Δ%= 3.5%, p< 0.01) and rMSSD (Δ%= −19.4%, p< 0.05) when compared dryland vs aquatic environment in RES. We observed similar results in rMSSD (Δ%= 49.2%, p< 0.01), pNN50(%) (Δ%= 79.1%, p< 0.01), and SD1 (Δ%= 49.3%, p< 0.01), during REC. Significant differences (p< 0.01) were also demonstrated for the HF during RES (Δ%= −43.4%) and REC (Δ%= −28.8%). However, the EG intra-group analysis showed no significant differences. The inter-group analysis at RES in dryland demonstrated significant differences in rMSSD (Δ%= −36.5%, p< 0.05), pNN50(%) (Δ%= −54.8%, p< 0.05), and SD1 (Δ%= 46.5%, p< 0.05). We also observed significant differences in mean R-R intervals (Δ%= −17.8%, p< 0.01), SDNN (Δ%= −41.2%, p< 0.01), rMSSD (Δ%= −50.5%, p< 0.01), pNN50 (Δ%= −73.6%, p< 0.001), and SD1 (Δ%= −50.4%, p< 0.001) during water immersion as well as the HF (Δ%= −67.6%, p< 0.01). The mean R-R interval (Δ%= −16.3%, p< 0.01), SDNN (Δ%= −46.4%, p< 0.001), rMSSD (Δ%= −57.0%, p< 0.001), pNN50 (Δ%= −73.1, p< 0.001), and SD1 (Δ%= −57.1, p< 0.001) also showed significant differences during REC. Water immersion increases the CG vagal modulation as expected. However, without any influence in EG. The results indicate a decreased vagal modulation in PLHIV in ART, indicating a possible autonomic dysfunction over the heart for this group.

Abstract Disorderly use of water resources has led to depletion, causing environmental and social issues. A relevant aspect to be observed in water supply systems is physical losses which occur during the system’s entire operational process. Many different software packages allow simulations of pressures and flow in water networks. The most used is EPANET. The epanet2toolkit is a recently developed R package that performs the interaction between EPANET and R. Based on this tool, a set of functions is developed to study and evaluate a theoretical network. The objective is to find an ideal network configuration (design) mainly for pressure management which simultaneously reduces physical losses. Water network parameters, such as roughness, reservoir levels, and diameters are used as parameters. A Monte Carlo simulation is generated, based on random values of these network parameters. From these, an ideal pressure scenario is found, resulting in a reduction of 11.6% in the occurrence of physical losses concerning the base case.

Resumo O uso desordenado dos recursos hídricos tem levado ao esgotamento, resultando no surgimento de questões ambientais e sociais. Um aspecto relevante a ser observado nos sistemas de abastecimento de água são as perdas físicas que ocorrem durante todo o processo operacional do sistema. Muitos pacotes de software diferentes permitem simulações de pressões e fluxos em redes de água. O mais utilizado é o EPANET. O epanet2toolkit é um pacote R recentemente desenvolvido que realiza a interação entre EPANET e R. Com base nesta ferramenta, são desenvolvidos um conjunto de funções para estudar e avaliar uma rede teórica. O objetivo é encontrar uma configuração de rede ideal (projeto) principalmente para gerenciamento de pressão que reduza simultaneamente as perdas físicas. Os elementos da rede hídrica, como rugosidade, níveis dos reservatórios e diâmetros são utilizados como parâmetros. Uma simulação de Monte Carlo é gerada, com base em valores aleatórios dos parâmetros desta rede. A partir destes, é encontrado um cenário de pressão ideal, resultando em uma redução de 11,6% na ocorrência de perdas físicas em relação ao caso base.

ABSTRACT The knowledge of the adequate period for the beginning of weed management in lettuce crop can increase the efficiency of production, reducing the costs with management. The aim of this study was to determine the pre-interference period (PIP), the critical time for weed removal (CTWR) and the critical period of weed control (CPWC) in three lettuce cultivars, Elisa, Lucy Brown and Solaris. Coexistence and the absence of weeds were evaluated for each cultivar. The design was in randomized blocks with seven treatments (0, 7, 14, 21, 28, 35 and 42 days after transplanting - DAT) of coexistence and the same seven periods of weed absence with four replicates in each experiment. The highest infestation densities were with the species Oxalis latifolia, Coronopus didymus and Amaranthus hybridus. The leaf area and number of leaves per plant were reduced by up to 50% and 66%, respectively, in relation to the longest period of coexistence with weeds and yield reduced by 48% (Elisa), 40% (Lucy Brown) and 33% (Solaris). The cultivar Solaris showed greater tolerance to weed interference. Based on yield, PIP was 1, 3 and 3 DAT and CTWR was 37, 37 and 35 DAT, and CPWC was 2 to 37, 3 to 37 and 3 to 35 for the cultivars Elisa, Lucy Brown and Solaris, respectively.

RESUMO O conhecimento do período adequado para início do manejo de plantas daninhas na cultura da alface pode aumentar a eficiência de produção reduzindo os custos com o manejo. Objetivou-se neste trabalho determinar o período anterior à interferência (PAI), o período total de prevenção da interferência (PTPI) e o período crítico de prevenção da interferência (PCPI) em três cultivares de alface, Elisa, Lucy Brown e Solaris. Foram avaliadas a convivência e a ausência de plantas daninhas para cada cultivar. O delineamento foi em blocos casualizados com sete tratamentos [0, 7, 14, 21, 28, 35 e 42 dias após transplantio (DAT)] de convivência e os mesmos sete períodos de ausência de plantas daninhas com quatro repetições em cada experimento. As maiores densidades de infestação foram com as espécies Oxalis latifolia, Coronopus didymus e Amaranthus hybridus. A área foliar e número de folhas por planta foram reduzidas em até 50% e 66% respectivamente em função do maior período de convivência com as plantas daninhas e produtividade foi reduzida em 48% (Elisa), 40% (Lucy Brown) e 33% (Solaris). A cultivar Solaris apresentou maior tolerância à interferência das plantas daninhas. Com base nos dados de produtividade o PAI foi de 1, 3 e 3 DAT e o PTPI foi de 37, 37 e 35 DAT, sendo o PCPI de 2 a 37, 3 a 37 e 3 a 35 para as cultivares Elisa, Lucy Brown e Solaris, respectivamente.

Abstract The planting of new types of table citrus is an interesting alternative for citrus growers in the state of Paraná, as this domestic market continues to grow and needs innovation. Thus, the aim of this study was to evaluate the acceptance and storage of a new hybrid for the region of Londrina / PR, Fremont IAC 543 mandarin (Citrus clementina hort. ex Tan x C. reticulataBlanco). Treatments were: storage of fruits with and without wax coating at room temperature [21 ± 2 °C and relative humidity (RH) = 60 ± 5%] for up to 36 days. Sensory (acceptance test and purchase intention) and physicochemical analyses [weight, juice yield, acidity, soluble solids and soluble solids/titratable acidity (ratio)] were performed before and after storage. Physicochemical data were submitted to analysis of variance and regression, while sensory analysis results were explored through descriptive statistics and principal components analysis using the R statistical software. It could be concluded that Fremont IAC 543 mandarin can be stored with wax coating and at room temperature without losing its quality characteristics for a period of up to 18 days.

ABSTRACT Purpose: The study aimed to evaluate the clinical and tissue response to a hollow polymethylmethacrylate orbital implant with a multiperforated posterior surface in an animal model after evisceration. Methods: Sixteen New Zealand rabbits had their right eye eviscerated. All animals received a hollow polymethylmethacrylate implant 12 mm in diameter that is multiperforated in its posterior hemisphere. The animals were divided into four groups, and each one had the eye exenterated at 7, 30, 90, and 180 days post-evisceration. Clinical signs were assessed daily for 14 days post-evisceration and then every 7 days until 180 days. Inflammatory pattern, collagen structure, and degree of neovascularization generated with implant placement were analyzed with hematoxylin-eosin, picrosirius red, and immunohistochemistry staining. Results: There were no signs of infection, conjunctival or scleral thinning, or implant exposure or extrusion in any animal during the study. On day 7, the new tissue migrated into the implant and formed a fibrovascular network through the posterior channels. Inflammatory response reduced over time, and no multinucleated giant cells were found at any time. Conclusion: Hollow polymethylmethacrylate orbital implants with a multiperforated posterior surface enable rapid integration with orbital tissues by fibrovascular ingrowth. We believe that this orbital implant model can be used in research on humans.

RESUMO Objetivo: Avaliar a resposta tecidual e clínica a um implante orbitário de polimetilmetacrilato, oco e multiperfurado em sua porção posterior em modelo animal após evisceração. Métodos: Dezesseis coelhos da raça Nova Zelândia foram submetidos à evisceração do globo ocular direito. Todos receberam implante oco de polimetilmetacrilato de 12 mm de diâmetro, multiperfurado em sua semiesfera posterior. O estudo foi dividido em avaliação clínica e histopatológica. A avaliação clínica foi diária até 14 dias pós-evisceração e, a cada sete dias, até completar 180 dias. Os animais foram divididos em grupos de quatro animais e cada um foi submetido à exenteração com 07, 30, 90 e 180 dias e depois à eutanásia. A análise histopatológica teve por fim caracterizar o padrão inflamatório, a estrutura do colágeno e o grau de neovascularização. Para isso, além da tradicional coloração pela hematoxilina-eosina, utilizou-se o corante Picrosirius Red (PSR) e imuno-histoquímica com o marcador CD 34. Resultados: Não houve sinais de infecção, afinamento conjuntival ou escleral, exposição ou extrusão do implante em nenhum animal durante o estudo. Já no sétimo dia, o tecido neoformado migrou para dentro do implante formando uma rede fibrovascular através dos canais posteriores. A resposta inflamatória diminuiu ao longo do tempo avaliado e não foram encontradas células gigantes multinucleadas. Conclusão: O implante analisado permite a sua integração aos tecidos orbitários pelo crescimento fibrovascular em seu interior. Os autores acreditam que este modelo de implante orbital pode fazer parte de testes com humanos.

SUMMARY OBJECTIVE: The aim of this study was to describe and discuss the epidemiological indicators of lip and oral cavity cancer in Brazil, in 2017, according to data from the Global Burden of Disease data. METHODS: This is a descriptive study reported according to STROBE guidelines. We identified epidemiological indicators using the Global Burden of Disease results tool. Mortality/incidence rates were described per 100,000 population. Global Burden of Disease 2017 reviews were completed using Python version 2.7, Stata version 13.1, and R version 3.3. RESULTS: In 2017, there were 5,237 deaths from the lip or oral cavity cancer in Brazil, most of them were males aged between 50 and 69 years (2,730 cases, which was equivalent to 52% of the universe of deaths resulting from this cause). Regarding the burden of lip and oral cavity cancer, per 100,000 Brazilians, we observed an incidence of 3.99, prevalence of 15.46, and mortality of 2.29 (with higher indicators in the South and Southeast regions of the country). CONCLUSIONS: Epidemiological indicators of lip and oral cavity cancer were higher in men, with higher mortality indicators in individuals aged 50–69 years, and higher rates (incidence, prevalence, and mortality) in the South and Southeast regions of Brazil. From 2002–2015, there was a reduction in mortality; however, in the period from 2015–2017, there was a resumption in the growth of this indicator.

Resumo A investigação da chuva de sementes pode fornecer informações úteis sobre a distribuição espacial, densidade e riqueza das espécies. O objetivo deste trabalho foi amostrar a chuva de sementes em Capões com presença e ausência de Copernicia prunifera (Carnaúba), caracterizar as sementes quanto à síndrome de dispersão e forma de vida, explorar a relação entre os totais pluviométricos mensais com a densidade e número de espécies da chuva de sementes e a estacionalidade na deposição de sementes. O estudo foi realizado em 20 Capões, sendo 10 com presença e 10 com ausência de Carnaúba. Cada Capão recebeu três coletores com área de 0,50 m2. Foram coletados 1.666 diásporos (55,5 sementes/m2) pertencentes a 17 famílias e 32 espécies. Houve relação negativa entre pluviosidade e número de sementes (r = -0,73 e p<0,05) e, entre pluviosidade e número de espécies da chuva de sementes (r = -0,78 e p<0,01). Houve aumento no número de espécies da chuva de sementes com o aumento de sementes da chuva de sementes (r = 0,74 e p< 0,001). Foram levantadas 908 sementes zoocóricas distribuídas em 12 espécies, anemocoria 502 sementes e 12 espécies e autocórica 256 sementes e sete espécies. As espécies arbóreas tiveram 895 sementes distribuídas em 12 espécies, os arbustos 574 sementes e 10 espécies, as Lianas 133 sementes e sete espécies e palmeiras com 61 sementes e duas espécies. As síndromes de dispersão anemocórica e zoocórica foram predominantes no período seco e zoocoria em todos os meses. Foi observada diferença na composição de espécies da chuva de sementes entre os Capões com presença e ausência de Carnaúba. A distância entre os Capões não influenciou na composição da chuva de sementes (Mantel r = -0,11e p = 0,74). Não houve relação entre áreas dos Capões com o número de sementes da chuva de sementes (R2 = 0,013 e p = 0,95).

Abstract Studies on seed rain can provide useful information on the spatial distribution, density, and richness of species. This study aimed to sample the seed rain in “capões” with the presence and absence of Copernicia prunifera (Carnaúba), characterizing the seeds as for their dispersion syndrome and life forms, and explore the relationship between the monthly rainfall totals and the density and number of species in the seed rain and the seasonality in seed deposition. The research was conducted in 20 capões, (10 with the presence and 10 with the absence of Copernicia prunifera). Three collectors of 0.50 m2 were placed in each capão. A total of 1,666 diaspores (55.5 seeds/m2), belonging to 17 families and 32 species, were collected. There was a negative relationship between rainfall and the number of seeds (r = -0.73 and p<0.05) and between rainfall and number of species in the seed rain (r = -0.78 and p<0.01). There was an increase in the number of species in the seed rain with an increase in the number of seeds (r = 0.74 and p<0.001). Twelve zoochoric, 12 anemochoric, and 7 autochoric species were recorded, which accounted for 908, 502, and 256 seeds, respectively. Trees had 895 seeds collected, distributed in 12 species, followed by shrubs (574 seeds and 10 species), lianas (133 seeds and 7 species), and palms (61 seeds and 2 species). Anemochoric and zoochoric dispersion syndromes predominated in the dry period, with a predominance of zoochory in all months. There was a difference in the species composition in the seed rain between the capões with the presence and with the absence of Copernicia prunifera. The distance between the capões did not influence the seed rain composition (Mantel r = -0.11 and p = 0.74). There was no relationship between areas of capões and the number of seeds in the seed rain (R2 = 0.013 and p = 0.95).

Resumo Objetivo A capacidade de acesso anterior à região cervicotorácica com base na idade e gênero do paciente e a possibilidade de variações anatômicas em diferentes populações geográficas ainda não foram investigadas. O objetivo deste trabalho foi realizar uma análise radiográfica de pacientes brasileiros para avaliar a acessibilidade anterior da junção cervicotorácica conforme idade e gênero. Métodos Análise radiográfica retrospectiva de 300 tomografias computadorizadas. Os pacientes foram separados por idade e gênero. Os parâmetros radiográficos estudados foram: nível horizontal acima do esterno (HLS, na sigla em inglês), angulação do corpo vertebral (VBA, na sigla em inglês), linha do disco intervertebral (IDL, na sigla em inglês) e angulação da linha do disco intervertebral (IDLA, na sigla em inglês). Resultados Os HLS e IDL mais frequentes foram T2 (34,3%) e C7-T1 (46%), respectivamente. Os valores médios de VBA e IDLA foram de 18 ± 8,94 e 19 ± 7,9 graus, respectivamente. Os homens apresentaram valores maiores de IDLA (p= 0,003) e VBA (p= 0,02). Os grupos de maior idade apresentaram valores maiores de IDLA (p= 0,01) e VBA (p= 0,001). Não houve diferenças de HLS entre os gêneros masculino e feminino (p= 0,3) ou faixas etárias (p= 0,79). Não foram observadas diferenças na IDL entre os gêneros masculino e feminino (p= 0,3); entretanto, o grupo mais velho apresentou nível mais caudal do que os grupos mais jovens (p= 0,12). ConclusõesEm comparação a outras populações, nossa amostra apresentou IDL e HLS mais cefálicos. AVBA e a IDLA foram maiores no gênero masculino, enquanto VBA e IDLA foram maiores em grupos mais velhos. A IDL era mais caudal em pacientes idosos.

Abstract Objective The approachability of the cervicothoracic region anteriorly based on age and gender, and the possibility of anatomic variances in different geographic populations have not been previously investigated. The aim of the present work was to perform a radiographic analysis of Brazilian patients to assess anterior approachability of the cervicothoracic junction based on age and gender. Methods Retrospective radiographic analysis of 300 computed tomography scans. Patients were separated based on age and gender. The radiographic parameters studied were: horizontal level above the sternum (HLS), vertebral body angle (VBA), intervertebral disc line (IDL), and intervertebral disc line angulation (IDLA). Results The most frequent HLS and IDL were T2 (34.3%) and C7-T1 (46%) respectively. Vertebral body angleand IDLA had average values of 18 ± 8.94 and 19 ± 7.9 degrees, respectively. Males had higher values in both IDLA (p= 0.003) and VBA (p= 0.02). Older groups had higher values in both IDLA (p= 0.01) and VBA (p= 0.001). No differences were observed in HLS between gender (p= 0.3) or age groups (p= 0.79). No differences were seen in IDL between gender groups (p= 0.3); however, the older group had a more caudal level than the younger groups (p= 0.12). ConclusionsCompared to other populations, our sample had a more cephalad IDL and HLS.

ABSTRACT. Phytophagous mites can cause economic losses in many crops, including grapevines. The changes in their population levels may be associated with changes in the predator-prey relationship. Knowledge of the distribution of mites in plants is important for planning sampling strategies and facilitating control decisions. The aims of this study were to (i) evaluate the abundances of Tetranychus urticae (Tetranychidae) and Neoseiulus californicus (Phytoseiidae), and the correlations between them and environmental factors; (ii) determine their distribution on the top, middle, or base strata of the evaluated grapevines (Vitis vinifera, Chardonnay cultivar) and, additionally, report the first occurrence of damage caused by T. urticae in grapevine leaves in the state of Rio Grande do Sul, Southern Brazil. Sixteen samplings were conducted, divided between the 2018 and 2019 seasons. In each sampling, three leaves from the three strata of the plant (top, middle, and base) were collected from 20 plants, totaling 60 leaves per sampling. The predator-prey relationship and their association with environmental variables were evaluated with multivariate correlation, whereas the number of mites per plant leaf strata was compared using a generalized linear mixed model in R software. It was possible to observe the symptoms of damage caused by T. urticae attacks on grapevines in Southern Brazil, characterized by the presence of yellow spots and general yellowing of the vineyard. Our findings indicate that T. urticae and N. californicus individuals are strongly associated with each other regardless of the environmental variables, and such relationship occurs mainly on the lower strata (middle and base leaves) of grapevines. Thus, by taking into account the damage on the leaves of grapevines and the occurrence of T. urticae and N. californicus majorities on specific strata of these vineyards, we suggest that the lower strata of grapevines should be the priority targets for management strategies to control such mites.

RESUMO Devido à baixa disponibilidade de ingredientes ativos de herbicidas, o manejo químico de plantas daninhas na cultura da alface é um desafio. Objetivou-se avaliar a sensibilidade da alface à aplicação dos herbicidas flumioxazin e trifluralin, isolados ou em mistura em pré-plantio de mudas de alface cultivar Lucy Brown. Dois experimentos foram realizados. O experimento A recebeu uma operação de revolvimento no solo antes da aplicação dos herbicidas e outra antes do transplantio das mudas; o experimento B recebeu apenas um revolvimento do solo anterior à aplicação do herbicida. O delineamento experimental foi em blocos casualizados em esquema fatorial (3x3) + 1 (2 fatores com 3 níveis e uma testemunha adicional) com 4 repetições. Ambos experimentos receberam os tratamentos herbicidas flumioxazin (120 g ha-1), trifluralin (450 g ha-1) e a associação flumioxazin + trifluralin (120 + 450 g ha-1) aplicados em três épocas distintas antecedendo o transplantio (0, 7 e 14 dias). A produtividade de alface após aplicação de trifluralin (48,4 t ha-1) foi maior do que sob aplicação de flumioxazin (16,8 t ha-1) no experimento A. No experimento B flumioxazin aos 14 DAT reduziu o número de folhas de alface (25,6), todavia não houve diferenças de produtividade. O herbicida trifluralin causou menores níveis de fitointoxicação na alface e foi o mais seletivo dentre os tratamentos quando aplicado nas três épocas nos dois experimentos.

ABSTRACT Due to the low availability of herbicide active ingredients, the chemical weed management in lettuce crop is a challenge. The aim of this study was to evaluate the sensitivity of lettuce to the pre-planting application of the herbicides flumioxazin and trifluralin alone or in tank-mixture in lettuce, Lucy Brown cultivar. Two experiments were conducted. In experiment A, the soil was tilled before the herbicide application and it was tilled again before seedling transplanting. In experiment B, the soil was tilled just once before the herbicide application. The experimental design was in randomized blocks in a factorial scheme (3x3) +1 (2 factors with 3 levels and an additional control) with 4 replicates. We applied flumioxazin (120 g ha-1), trifluralin (450 g ha-1) and flumioxazin + trifluralin (120 + 450 g ha-1) in three different seasons before transplanting (0, 7 and 14 days). Lettuce productivity after trifluralin application (48.4 t ha-1) was higher than after flumioxazin application (16.8 t ha-1) in experiment A. In experiment B, flumioxazin decreased the number of lettuce leaves (25.6) at 14 DAT; no differences in lettuce productivity were verified, though. The herbicide trifluralin caused lower levels of phytotoxicity and was the most selective between the treatments when applied in the three seasons in both experiments.

Resumo O objetivo deste estudo clínico, é avaliar o impacto da desinfecção bucal completa (DBC) nos níveis de nitrito salivar e biomarcadores sistêmicos e sua correlação com a carga bacteriana subgengival total em pacientes obesos e não obesos com periodontite. No total, 94 pacientes (55 obesos e 39 não obesos) foram avaliados inicialmente, sete foram perdidos durante o estudo, resultando em 87 indivíduos ao final. Os resultados foram avaliados no início do estudo, 3, 6 e 9 meses após o tratamento periodontal por DBC. Os níveis de nitrito salivar foram determinados usando o reagente de Griess. Amostras de sangue foram coletadas para determinação da Proteína C Reativa (PCR), fosfatase alcalina e glicemia de jejum. A PCR em tempo real foi usada para determinar a carga bacteriana subgengival total. O protocolo de DBC resultou em níveis aumentados de nitrito salivar em 6 e 9 meses após o tratamento no grupo de não obesos (p <0,05). Em indivíduos obesos, o tratamento da DBC levou a um aumento nos níveis de nitrito salivar em 6 meses (p <0,05); no entanto, aos 9 meses, os níveis de nitrito voltaram aos níveis basais. Para ambos os grupos, os maiores valores de nitrito foram observados aos 6 meses. Além disso, em ambos os grupos, a DBC foi associada à diminuição dos biomarcadores relacionados à inflamação sistêmica e doenças cardiovasculares, como PCR (p <0,05) e fosfatase alcalina (p <0,05), e não teve impacto na glicemia de jejum. Este estudo demonstra que pacientes obesos com periodontite apresentam níveis de nitrito salivar semelhantes quando comparados a indivíduos não obesos. O protocolo de DBC resultou em aumentos nos níveis de nitrito salivar e foi associado a um impacto positivo nos biomarcadores sistêmicos, independentemente do status de obesidade.

Abstract The objective of this 9-month clinical study is to assess the impact of one-stage full-mouth disinfection (FMD) on salivary nitrite levels and systemic biomarkers and its correlation with total subgingival bacterial load in obese and non-obese patients with periodontitis. In total, 94 patients (55 obese and 39 non-obese) were initially evaluated, seven were lost during follow-up, resulting in 87 individuals at the end of the study. Outcomes were assessed at baseline, 3, 6, and 9 months post periodontal treatment by FMD. Salivary nitrite levels were determined using Griess reagent. Blood samples were collected to determine C-Reactive Protein (CRP), alkaline phosphatase and fasting blood glucose. Real-time PCR was used to determine the total subgingival bacterial load. FMD protocol resulted in increased salivary nitrite levels at 6- and 9-months post-treatment in the non-obese group (p<0.05). In obese individuals, FMD treatment led to an increase in salivary nitrite levels at 6 months (p<0.05); however, at 9 months, the nitrite levels returned to baseline levels. For both groups, the highest nitrite values were observed at 6 months. In addition, in both groups, FMD was associated with a decrease in biomarkers related to systemic inflammation and cardiovascular diseases, such as CRP (p<0.05) and alkaline phosphatase (p<0.05), and had no impact on the fasting blood glucose. This study demonstrates that obese patients with periodontitis present similar salivary nitrite levels when compared with non-obese individuals. FMD protocol resulted in increases in salivary nitrite levels and was associated with a positive impact on systemic biomarkers, regardless of obesity status.

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

ABSTRACT OBJECTIVE To describe the evolution of seropositivity in the State of Rio Grande do Sul, Brazil, through 10 consecutive surveys conducted between April 2020 and April 2021. METHODS Nine cities covering all regions of the State were studied, 500 households in each city. One resident in each household was randomly selected for testing. In survey rounds 1–8 we used the rapid WONDFO SARS-CoV-2 Antibody Test (Wondfo Biotech Co., Guangzhou, China). In rounds 9–10, we used a direct ELISA test that identifies IgG to the viral S protein (S-UFRJ). In terms of social distancing, individuals were asked three questions, from which we generated an exposure score using principal components analysis. RESULTS Antibody prevalence in early April 2020 was 0.07%, increasing to 10.0% in February 2021, and to 18.2% in April 2021. In round 10, self-reported whites showed the lowest seroprevalence (17.3%), while indigenous individuals presented the highest (44.4%). Seropositivity increased by 40% when comparing the most with the least exposed. CONCLUSIONS The proportion of the population already infected by SARS-Cov-2 in the state is still far from any perspective of herd immunity and the infection affects population groups in very different levels.
