Abstract: Pt Es En

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

Abstract Background: Methotrexate (MTX) is an alternative treatment for patients with moderate/severe atopic dermatitis (AD). Objective: The authors evaluated the effect of MTX on the cutaneous expression of cytokines and chemokines that are involved in the inflammatory response in adult AD patients who received treatment with methotrexate for 24 weeks. Methods: The authors conducted a prospective single-institution cohort study with 12 adults with moderate/severe AD who received oral MTX (15 mg/wk for 24 wks) and 10 non-atopic matched controls. The comparison was made of skin biopsies of lesional and non-lesional skin, pre- and post MTX treatment. The authors analyzed mean epidermal thickness and expression of IL-31, IL-31RA, OSMR, TSLP, Ki67, IL-4 mRNA, IL-6, IL-10, TNF-α, IFN-γ, TARC, and CCL-22. Results: There was a reduction in mean epidermal thickness (p = 0.021), an increase in IL-31RA expression (immunohistochemistry) in the epidermis (p = 0.016) and a decrease in IL-31 gene expression (p = 0.019) on lesional AD skin post-MTX treatment. No significant changes in the cutaneous expression of the other evaluated markers were identified. Study limitations: Small sample size and limited length of follow-up. Conclusions: Treatment with MTX in adults with moderate/severe AD reduced epidermal hyperplasia and changed the cutaneous expression of inflammatory cytokines and receptors that are mainly related to pruritus, including IL-31 and IL-31RA.

ABSTRACT Classical developmentalism was heterodox economics that showed countries require a moderate intervention of the state in the economy to industrialize and catch up. Growth depends on investments and on a satisfying expected rate of profit, which import tariffs legitimized by the infant industry argument assure. Latin American countries adopted this industrial policy from the 1950s and experienced high growth rates. But the infant argument loses validity with time. In the 1980s, under the pressure of the Global North, Latin American countries adopted the neoliberal reforms, and are quasi-stagnant since then. New developmentalism emerged in the 2000s, made the critique of conventional economics, proposed a new growth strategy focused on a competitive exchange rate, and legitimized the use of import tariffs with the Dutch disease argument.

RESUMO O desenvolvimentismo clássico é uma teoria econômica heterodoxa que mostrou que os países precisam de intervenção moderada do Estado na economia para se industrializar. Os países latino-americanos adotaram essa política industrial a partir da década de 1950 e tiveram altas taxas de crescimento. Mas o argumento da indústria nascente perde validade com o tempo. Na década de 1980, sob a pressão do Norte, os países latino-americanos adotaram as reformas neoliberais e estão quase estagnados desde então. O novo desenvolvimentismo surgiu nos anos 2000, fez a crítica da economia convencional, formulou uma macroeconomia do desenvolvimento baseada nos cinco preços macroeconômicos, desenvolveu um argumento contraintuitivo contra a política de crescimento com endividamento e poupança externa e a retomada de tarifas de importação para neutralizar a doença holandesa.

Abstract Objective Evaluate autonomic function and low-grade inflammation and characterize the correlation between these variables in schoolchildren with obesity living in the Brazilian northeast region. Methods 84 children with obesity and 41 with normal weight were included in this cross-sectional study. Anthropometry, body composition, blood pressure (BP), inflammatory biomarkers, and heart rate variability (HRV) indexes were analyzed in children aged 7 to 11 years. Results children with obesity had increased systolic (p= 0.0017) and diastolic (p= 0.0131) BP and heart rate (p= 0.0022). The children with obesity displayed significantly lower SDNN, RMSSD, NN50, HF (ms), HF (nu), SD1, SD2, and higher LF (ms), LF (nu), LF/HF, SD1/SD2, DFA-α1, and DFA-α2, compared to normal weight. A lower and higher capacity for producing IL-10 (p= 0.039) and IL-2 (p= 0.009), respectively, were found in children with obesity compared to children with normal weight. Although IL-2, IL-4 and IL17A did not correlate with HRV parameters, IL-6 was positively correlated with SDNN, LF (ms) and SD2, TNF-α was positively correlated with LF/HF and SD1/SD2 ratio, and IFN-γ was positively correlated with SDNN, RMMSSD, NN50, LF (ms), HF (ms), SD1, and SD2. Conclusions The findings suggest that children with obesity have impaired autonomic function and systemic low-grade inflammation compared to children within the normal weight range, the inflammatory biomarkers were correlated with HRV parameters in schoolchildren living in the northeastern region of Brazil.

ABSTRACT In semi-arid regions, where seasonal drought or irregular rainfall distribution are common occurrences, agricultural management techniques or strategies, such as the use of bone meal and/or hydrogel, can mitigate adverse conditions and ensure crop production. This study aimed to evaluate the efects of bone meal doses (0, 250, 500, 750 and 1,000 g pit−1), in association or not with hydrogel (0 and 5 g pit−1, respectively), on the leaf nutrient content of the dwarf cashew cultivar BRS 226. The leaf nutrient contents were evaluated during two growing seasons. For being a good source of macronutrients, the bone meal increased the levels of N, P, Ca, K and Mg in the dwarf cashew leaves. The leaf contents of the micronutrients Zn, Fe and Mn decreased with increasing bone meal doses. The nutrient accumulation in the leaves of the dwarf cashew planted in pits with bone meal and hydrogel has the following order: N > K > Ca > Mg > P > Mn > Fe > Zn > Cu. The application of bone meal at levels close to 600 g pit−1, mainly with the use of hydrogel, is a viable fertilizer alternative for dwarf cashew.

RESUMO Em regiões semiáridas, onde a seca sazonal ou a distribuição irregular de chuvas são ocorrências comuns, técnicas ou estratégias de manejo agrícola, como o uso de farinha de osso e/ou hidrogel, podem mitigar condições adversas e garantir a produção agrícola. Objetivou- se avaliar os efeitos de doses de farinha de osso (0, 250, 500, 750 e 1,000 g cova−1), em associação ou não com hidrogel (0 e 5 g cova−1, respectivamente), sobre o teor de nutrientes foliares da cultivar de cajueiro-anão BRS 226. Os teores de nutrientes nas folhas foram avaliados durante duas safras. Por ser boa fonte de macronutrientes, a farinha de osso aumentou os níveis de N, P, Ca, K e Mg nas folhas do cajueiro anão. Os teores foliares dos micronutrientes Zn, Fe e Mn diminuíram com o aumento das doses de farinha de osso. O acúmulo de nutrientes nas folhas do cajueiro anão plantado em covas com farinha de osso e hidrogel tem a seguinte ordem: N > K > Ca > Mg > P > Mn > Fe > Zn > Cu. A aplicação de farinha de osso em níveis próximos a 600 g cova−1, principalmente com o uso de hidrogel, é uma alternativa viável de fertilizante para cajueiro-anão.

Contents related to the modern physics field involve the knowledge of the production and interaction of radiation with matter. The attenuation of the radiation evidences the macroscopic manifestation of this interaction. This study presents an apparatus intended for teaching practices to determine the lead mass attenuation coefficient for gamma-ray photons from a source of 137Cs (photons with energy of approximately 662 keV). Traditionally, this determination is performed using lead plates of known thicknesses. However, this focus generally produces discrepant results related to the mass attenuation coefficient adopted values, with deviations around 15%. In the approach presented here, which is innovative, the plates were replaced by small spheres or powders of the analyzed material (lead). The results show that this substitution significantly reduced the deviations from the theoretical values. In the best experimental condition, the errors were between 2% and 4% for the spheres and the powder, respectively. Among the advantages of the proposed method are the possibility of continuous variations in the thickness and the geometry of the attenuating material, and the analysis of the influence of porous systems on the measurement of radiation attenuation.

Conteúdos relacionados à área de Física Moderna envolvem o conhecimento da produção e interação da radiação com a matéria. A manifestação macroscópica dessa interação se evidencia pela atenuação da radiação incidente no material. Neste estudo, apresenta-se o uso de um aparato experimental destinado a práticas de ensino visando a determinação do coeficiente de atenuação do chumbo para fótons de raios gama provenientes de uma fonte de 137Cs (fótons com energia de aproximadamente 662 keV). Tradicionalmente, essa determinação é realizada utilizando-se como material absorvedor placas de chumbo de espessuras conhecidas. Entretanto, em geral, esse enfoque leva a resultados discrepantes em relação ao valor do coeficiente de atenuação teórico para o chumbo, com desvios em torno de 15%. No método aqui apresentado, sugere-se a substituição das placas por esferas ou pó de chumbo. Os resultados obtidos mostram que o método proposto reduziu sensivelmente os desvios do coeficiente de atenuação medido em relação aos valores teóricos (simulados). Na melhor condição experimental os erros ficaram entre 2 e 4%. Entre as grandes vantagens do método abordado estão à possibilidade de variações contínuas na espessura e na geometria do material absorvedor e análise da influência de sistemas porosos na medida da atenuação da radiação.

Os hábitos de consumo de refeições específicas têm sido abordados em diversos estudos, no entanto, a avaliação dos padrões refeições tem recebido menos atenção. O objetivo deste estudo foi descrever os padrões de refeições da população brasileira. Um desenho amostral complexo foi utilizado para selecionar os 46.164 indivíduos de ≥ 10 anos examinados no Inquérito Nacional de Alimentação de 2017-2018. O consumo alimentar foi avaliado por meio de dois recordatórios de 24 horas não consecutivos, aplicados durante um período de uma semana. A análise exploratória de dados foi utilizada para determinar os padrões de refeições, ou seja, como os indivíduos combinam as principais refeições (café da manhã, almoço, jantar) e lanches (manhã, tarde, noite) ao longo do dia. Os padrões de refeições mais frequentes foram três refeições principais + um lanche, conforme relatado por 25,1% dos indivíduos, e três refeições principais + dois lanches (24,6%). Outros padrões de refeições identificados foram: três refeições principais + três lanches (18,5%); três refeições principais e nenhum lanche (10,9%); uma ou duas refeições principais + dois lanches (7,4%); uma ou duas refeições principais + um lanche (6,9%); uma ou duas refeições principais + três lanches (4,2%); e uma ou duas refeições principais e nenhum lanche (2,3%). Os padrões de refeições variaram de acordo com o sexo e a faixa etária, e nos dias típicos em comparação com os atípicos de consumo alimentar. Verificou-se que oito padrões caracterizaram o consumo diário de refeições no Brasil. Além disso, cerca de 80% da população realizava três refeições principais diárias e cerca de 13% reportaram não lanchar. A caracterização dos padrões de refeições é importante para adequar e direcionar ações de promoção da saúde.

The habit of eating specific meals has been addressed in several studies, but the evaluation of meal patterns has received less attention. This study aimed to describe the meal patterns of the Brazilian population. A complex sampling design was used to select the 46,164 ≥ 10-year-old individuals examined in the Brazilian National Dietary Survey. Food consumption was assessed by two non-consecutive 24-hour recalls applied throughout a one-week period. The exploratory data analysis approach was used to determine the meal patterns, i.e., how individuals combined the main meals (breakfast, lunch, dinner) and snacks (morning, afternoon, evening/night) throughout the day. The most common meal patterns were three main meals + one snack, reported by 25.1% of the individuals, and three main meals + two snacks (24.6%). Other meal patterns identified were: three main meals + three snacks (18.5%); three main meals and no snacks (10.9%); one or two main meals + two snacks (7.4%); one or two main meals + one snack (6.9%); one or two main meals + three snacks (4.2%); and one or two main meals and no snacks (2.3%). Meal patterns varied according to gender and age group, and on typical versus atypical food consumption days. We found that eight patterns characterized the daily meal consumption in Brazil. Furthermore, around 80% of the population had three main meals every day and about 13% did not report having any snacks. The characterization of meal habits is important for tailoring and targeting health promotion actions.

Los hábitos alimenticios específicos se han abordado en varios estudios, sin embargo, poco se sabe sobre la evaluación de los patrones de alimentación. El objetivo de este estudio fue describir el patrón de alimentación de la población brasileña. Se utilizó un diseño de muestra complejo para seleccionar a 46.164 individuos de ≥ 10 años quienes participaron en la Encuesta Nacional de Alimentación 2017-2018. El consumo alimentario se evaluó mediante dos registros de 24 horas no consecutivos, aplicados durante una semana. Para determinar el patrón de alimentación, se aplicó el análisis exploratorio, es decir, cómo las personas combinan las comidas principales (desayuno, almuerzo, cena) y las meriendas (mañana, tarde, noche) a lo largo del día. Los patrones de alimentación más frecuentes fueron tres comidas principales + una merienda según informan el 25,1% de los individuos, y tres comidas principales + dos meriendas (24,6%). Otros patrones identificados destacaron tres comidas principales + tres meriendas (18,5%); tres comidas principales sin merienda (10,9%); una o dos comidas principales + dos meriendas (7,4%); una o dos comidas principales + una merienda (6,9%); una o dos comidas principales + tres meriendas (4,2%); y una o dos comidas principales sin merienda (2,3%). Los patrones de alimentación tuvieron una variación según el sexo y el grupo de edad, y en días típicos en comparación con los atípicos de consumo de alimentos. Se encontró que ocho patrones caracterizan el consumo diario de comidas en Brasil. Por lo tanto, aproximadamente el 80% de la población tienen tres comidas principales al día y aproximadamente el 13% informan que no tienen merienda. Es importante caracterizar los patrones de alimentación para adaptar y orientar las acciones de promoción de la salud.

Abstract This study examined the oral health-related therapeutic itineraries of quilombola adults in a rural district of Vitória da Conquista, Bahia. This qualitative study involved ten semi-structured interviews of adult members of the quilombola community, in May 2021, which were then transcribed and analysed using content analysis. The results showed little or poor oral hygiene at some stage of life, especially in childhood and adolescence, the use of popular oral health care practices, and experiences of professional care featuring tooth extraction. Use of health services was mostly reported only in the period prior to the COVID-19 pandemic. Responses as to perceived ease of access to health services in the community varied. One common complaint as to satisfaction with oral health was the need to use or replace dental prostheses. This study concluded that oral health must be promoted jointly with disease prevention, dental rehabilitation and recognition for the knowledge and worldview of the quilombola population.

Resumo O estudo analisou os itinerários terapêuticos relacionados à saúde bucal de adultos quilombolas de um distrito rural de Vitória da Conquista, Bahia. Trata-se de uma pesquisa qualitativa, na qual foram realizadas dez entrevistas semiestruturadas com adultos quilombolas em maio de 2021, transcritas e analisadas por meio da análise de conteúdo. Os resultados evidenciaram ausência e/ou precariedade na higiene bucal em alguma fase da vida, especialmente infância e adolescência; utilização de práticas populares para cuidado a saúde bucal e experiências de cuidado profissional marcados pela exodontia. A utilização de serviços de saúde foi relatada, em sua maioria, apenas no período anterior à pandemia de COVID-19, os entrevistados divergiram quanto à percepção de facilidade do acesso aos serviços de saúde em sua comunidade. Os relatos sobre a satisfação da saúde bucal destacaram a necessidade de uso ou substituição de próteses dentárias. À guisa de conclusão, entende-se que é necessária a promoção de saúde bucal de forma articulada com ações que possibilitem a prevenção de agravos, a reabilitação odontológica e a valorização do conhecimento e da visão de mundo da população quilombola.

ABSTRACT Agroecological management is considered a model of sustainable agriculture that offers social, environmental and economic benefits. The hypotheses of this study were that agroecological production systems can promote changes in the physical fractions of soil organic matter (SOM) associated with aggregates of different origins, and that the greater diversity of plant species in the production system may favour an increase in the carbon concentration of these aggregates. The aim of this study was to a) determine the mass of the free light fraction (FLF), intra-aggregate light fraction (ILF) and light organic matter fraction (LOM) of biogenic and physiogenic soil aggregates; and b) quantify the organic carbon content of the three light SOM fractions and the residual particulate SOM fraction. Five production systems were evaluated: AgF - Agroforestry system; CSun - Coffee grown in full sun; CSha - Coffee grown in shade; FLE - Flemingia grown in alleys; and NT - No-tillage. The aggregates were separated, identified and classified according to their origin or formation pathway into biogenic (formed by biological processes) or physiogenic aggregates (resulting from chemical and physical actions). From these, the mass and carbon content of the FLF, ILF, LOM and residual particulate fractions were quantified. The greater diversity of plant species found in the AgF system has not yet favoured an increase in the carbon content of the aggregates. The longer set-up time and the management practices of the CSun system has led to an increase in the carbon content of the organic fractions of the aggregates (3.44-1.63 g kg-1 for C-LOM; 1.93-1.13 g kg-1 for C-FLF). The lowest overall mean values for LOM and ILF were found mainly in the aggregates of the NT system (1.22-1.67 and 1.55-2.20 g kg-1, respectively), being associated with the shorter time and greater mobilisation of the arable layer. Biogenic aggregation afforded the highest overall mean values for LOM, and increased the mass of the light fractions (15.5%-27.8% for FLF; 23.4%-8.0% for ILF) and the carbon in the C-LOM, C-FLF and residual particulate fractions (42.3%, 12.9%, and 35.0%, respectively) in the surface layer, suggesting an improvement in soil quality.

ABSTRACT BACKGROUND: Specific types of violence such as intimate partner sexual violence and intimate partner homicide occur more frequently in rural areas. OBJECTIVE: This study aimed to systematically review the literature on the knowledge and attitudes of rural healthcare providers regarding cases of domestic violence against women. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia. METHODS: We conducted an electronic search of six databases, which only included observational studies, regardless of the year, language, or country of publication, except for studies that used secondary data and were exclusively qualitative. Two reviewers performed the selection, data extraction, and risk of bias assessment using a specific Joanna Briggs Institute tool. RESULTS: Six studies met the inclusion criteria. All the studies had a low risk of bias. Approximately 38% of these professionals identified injuries caused by violence in patients. When asked about knowing the correct attitude to take in cases of confirmed violence, between 12% and 64% of rural healthcare providers answered positively; most of them would refer to specialized institutions and promote victim empowerment and counseling. The number of professionals with an educational background in the field ranged from 16% to 98%. CONCLUSIONS: The evident disparity across studies shows that some professionals have suboptimal knowledge and require training to adopt the correct attitude when identifying female victims of domestic violence in clinical practice. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered in the Open Science Framework Database under the registration http://doi.org/10.17605/OSF.IO/B7Q6S.

ABSTRACT The use of carp pituitary extract (CPE) in fish reproduction may have drawbacks, whereas analogues of mammalian (aGnRHm) or salmon (aGnRHs) gonadotropins containing dopamine inhibitor (DI) may offer greater advantages. The objective of this study was to evaluate the effect of different hormone inducers on the reproduction of Prochilodus brevis males. A total of 44 specimens of P. brevis were divided into six groups, namely, CPE 4.0 mg; saline solution 1.0 mL; aGnRHm + DI 0.3 mg and 0.5 mg; and aGnRHs + DI 0.25 mL and 0.35 mL kg-1 of live weight. The number of ejaculates, seminal volume, curvilinear velocity (VCL), straight-line velocity (VSL), average path velocity (VAP), sperm morphology and concentration, and membrane and DNA integrity were determined. Sample normality was examined using the Shapiro-Wilk test, and homogeneity using the Levene test. Analysis of variance (ANOVA) was conducted, followed by Tukey's test to compare means, with statistical significance set at p < 0.05. Notably, all fish induced with CPE 4.0 and aGnRHm + DI demonstrated ejaculation, yielding a greater seminal volume. Sperm concentration under aGnRHs + DI 0.35 exceeded that with aGnRHm + DI 0.3 and CPE 4.0. Regarding velocity, aGnRHm + DI 0.3 outperformed aGnRHs + DI 0.35 in VCL, while aGnRHm + DI 0.3 and 0.5 and aGnRHs + DI 0.25 led to higher VSL than aGnRHs 0.35. Additionally, VAP was elevated under aGnRHm + DI 0.3 and CPE, in contrast to aGnRHs + DI 0.35. Improved sperm morphology was observed with aGnRHm + DI 0.5 and aGnRHs + DI 0.25 compared to aGnRHm + DI 0.3. The remaining parameters did not differ significantly.

ABSTRACT Objective: To analyze functional aspects of breastfeeding, self-efficacy, and pain reported by mothers during breastfeeding, in newborns with severe and mild ankyloglossia. Methods: This is an observational study, carried out with 81 babies with ankyloglossia, assessed by the Bristol Tongue Assessment Tool (severe: scores 0–3; mild: scores 4–6) nested in a cohort carried out at the University Hospital of the Federal University of Maranhão, São Luis, Brazil. The functional aspects of breastfeeding were analyzed using the Breastfeeding Observation Form of the United Nations Children's Fund (BOF-UNICEF) and the LATCH Scoring System. Breastfeeding self-efficacy was measured using the Breastfeeding Self-Efficacy Scale — Short-Form. Pain indicators were evaluated by the Short-Form McGill Pain Questionnaire. The significance level adopted was 5%. Results: Maternal age was 26.7±0.8 years, and 64.2% reported high school education. Most babies were male (67.9%), and the birth weight was 3232±60g. A significant association was detected in the sucking aspect evaluated by the BOF-UNICEF [β=0.22 (95%CI 0.07; 0.73), p-value=0.013]. However, the groups did not differ in the assessment of breastfeeding performed by the LATCH scale. The groups had no differences in the assessment of breastfeeding self-efficacy reported by mothers, and in pain scores. Conclusions: Despite the observation of sucking difficulty in infants with severe ankyloglossia., the quality of breastfeeding in general, maternal pain, and self-efficacy reported by mothers do not differ when compared with infants with mild ankyloglossia. Therefore, the severity of ankyloglossia seems not to affect the breastfeeding indicators.

RESUMO Objetivo: Analisar aspectos funcionais da amamentação, autoeficácia e dor relatada pelas mães durante a amamentação, em recém-nascidos com anquiloglossia grave e leve. Métodos: Estudo observacional, realizado com 81 bebês diagnosticados com anquiloglossia avaliados pelo Bristol Tongue Assessment Tool (grave: escores 0–3; leve: escores: 4–6), aninhados em um estudo de coorte realizado no Hospital Universitário da Universidade Federal do Maranhão, São Luís, Brasil. Os aspectos funcionais do aleitamento materno foram analisados por meio do Formulário de Observação da Amamentação do Fundo Internacional para a Infância das Nações Unidas (BOF-UNICEF) e da Escala LATCH. Aautoeficácia foi mensurada por meio da Breastfeeding Self-Efficacy Scale — Short-Form. Os indicadores de dor foram avaliados pelo Short-Form McGill Pain Questionnaire. O nível de significância adotado foi de 5%. Resultados: A idade materna foi 26,7±0,8 anos, e 64,2% concluíram o ensino médio. A maioria dos recém-nascidos era do sexo masculino (67,9%), e o peso ao nascer foi 3232±60g. Foi detectada associação significante no aspecto da sucção avaliado pelo BOF-UNICEF [β=0,22 (IC95% 0,07; 0,73), p=0,013]. No entanto, os grupos não diferiram na avaliação do aleitamento materno realizada pela escala LATCH. Os grupos não apresentaram diferenças na avaliação da autoeficácia em amamentar relatada pelas mães e no escore de dor. Conclusões: Apesar de ter sido observada dificuldade de sucção em lactentes com anquiloglossia grave, a qualidade da amamentação em geral, a dor materna e a autoeficácia relatada pelas mães não diferem quando comparadas com as de lactentes com anquiloglossia leve. Assim, a gravidade da anquiloglossia parece não afetar os indicadores de amamentação.

ABSTRACT: Pythiosis is the disease caused by aquatic oomycetes of the genus Pythium. In dogs the typical course of the disease involves the gastrointestinal tract, characterized by transmural thickening of the stomach or intestines. However, infection by Pythium spp. has only rarely been recognized as a cause of esophagitis in dogs. Thus, the present reports a case of esophageal and gastric pythiosis in an eight-month-old female pit bull dog. The dog was attended at the hospital after two months presenting regurgitation and dyspnea. It was reported that the dog lived in an urban area and had no previous sanitary issues. At clinical examination it was noted that the dog presented crackling sounds at pulmonary auscultation. A support therapy accompanied by antibiotics has been employed; however, 22 days after hospitalization the clinical condition worsened, and the dog died. At necropsy, the wall of the distal segment of the esophagus and the cardia and part of the fundus of the stomach were expanded by a focal extensive irregular intramural annular mass. Additionally, there was a transmural esophageal fistula. At histology, the walls of the esophagus and stomach were extensively expanded by multifocal extensive areas of necrosis, associated with a pyogranulomatous infiltrate and abundant granulation tissue containing multiple negative images of hyphae that were highlighted by silver impregnation (Grocott). Furthermore, immunohistochemistry and PCR for P. insidiosum were both positive in samples of paraffin-embedded esophageal tissue.

RESUMO: A Pitiose é uma doença causada por oomicetos aquáticos do gênero Pythium. Em cães o curso típico da doença envolve o trato gastrointestinal, caracterizado por espessamento transmural do estômago ou intestinos. No entanto, a infecção por Pythium spp. raramente foi reconhecida como causa de esofagite em caninos. Assim, o presente trabalho tem como objetivo relatar um caso de pitiose esofágica e gástrica em um canino Pit Bull fêmea de oito meses de idade. O cão foi recebido no hospital com histórico de regurgitação e dispneia durante dois meses. Foi relatado que o animal era de um domicílio de área urbana e não possuía histórico pregresso de enfermidades. No exame clínico contatou-se ainda crepitações à ausculta pulmonar. Foi instituído tratamento de suporte e antibioticoterapia, porém após 22 dias de internação, o cão evoluiu para o óbito. Na necropsia, as paredes do segmento distal do esôfago e o cárdia e parte do fundo do estômago estavam expandidos por uma massa anular intramural focalmente extensiva e irregular. Além disso, havia uma fístula esofágica transmural. À histologia, as paredes do esôfago e do estômago apresentavam-se difusamente expandidas por áreas multifocais extensas de necrose, associadas a infiltrado piogranulomatoso, abundante proliferação de fibroblastos imaturos, neovascularização e contendo múltiplas imagens negativas de hifas realçadas pela impregnação por prata (Grocott). Além disso, tanto a imuno-histoquímica como PCR para P. insidiosum foram positivas em amostras de esôfago embebidas em parafina.

Resumo Este artigo propõe uma reflexão sobre o imperativo do antirracismo na saúde bucal coletiva, a qual, como núcleo e práxis, pode contribuir de forma significativa para a (re)construção de um ethos que contemple a equidade e viabilize a cidadania e a democracia. Como paradigma, assumimos o conceito “Bucalidade” e as diretrizes da Política Nacional de Saúde Integral da População Negra, pela ênfase no direito à saúde como prerrogativa do direito à vida e no combate ao racismo e a todas as formas de discriminação, em quaisquer espaços, como indutor desse ethos. Como exercício crítico, abordamos o status quo da saúde bucal coletiva e apontamos para uma perspectiva pró-equidade racial como uma escolha intencional, política e pactuada socialmente em busca da justiça social. Por fim, trazemos proposições para a implementação desse ethos por assumir o enfrentamento do racismo sistêmico no campo da saúde bucal coletiva como inadiável para a preservação da vida-boca e aprimoramento da democracia. qual práxis reconstrução re construção democracia paradigma Bucalidade “Bucalidade Negra discriminação espaços crítico próequidade pró intencional social fim vidaboca boca

Abstract This article proposes a reflection on the imperative of antiracism in collective oral health, which, as a science, field, core, and praxis, contributes significantly to the reconstruction of an ethos that considers equity and enables citizenship and democracy. As a paradigm, we assumed the concept of “Buccality” and the guidelines of the National Comprehensive Health Policy for the Black Population, emphasizing the defense of the right to health as a prerogative of the right to life and the combat against racism and all forms of discrimination systematically. As a critical exercise, we discussed the status quo of collective oral health. We pointed to adopting a racial pro-equity perspective as an intentional, political choice socially agreed upon with all of society for social justice. Finally, we propose recommendations for dismantling systemic racism in collective oral health. which science field core praxis democracy paradigm Buccality “Buccality Population systematically exercise proequity pro intentional justice Finally
