Abstract Objectives: to analyze the factors associatedwith dental cavity in early childhood. Methods: this is a cross-sectional study on oral health condition of 535 children aged between six and 36 months old, at Family Health Units, in Salvador-BA. Information was collected on socioeconomic conditions, mother and child’s health, eating and oral hygiene habits, and oral examination. Results: the prevalence of dental cavity was 13.64% (CI95%=11.44 -15.84) and the factors associated were: child’s age, number of rooms in the house, “Bolsa Família” (Family Welfare) benefit, prenatal consultations, birth weight and exclusive breastfeeding. Conclusions: socioeconomic conditions strongly influenced oral health, as well as prenatal care and breastfeeding. To prevent childhood cavities, it is pertinent to invest in intersectoral actions and systematized programs, including the medical and nursing staff, as these actions are essential for integral care for the child’s health and quality of life

Abstract Background: Diabetes mellitus (DM) has glucose variability that is of such relevance that the appearance of vascular complications in patients with DM has been attributed to hyperglycemic and dysglycemic events. It is known that T1D patients mainly have glycemic variability with a specific oscillatory pattern with specific circadian characteristics for each patient. However, it has not yet been determined whether an oscillation pattern represents the variability of glycemic in T2D. This is why our objective is to determine the characteristics of glycemic oscillations in T2D and generate a robust predictive model. Results: Showed that glycosylated hemoglobin, glycemia, and body mass index were all higher in patients with T2D than in controls (all p < 0.05). In addition, time in hyperglycemia and euglycemia was markedly higher and lower in the T2D group (p < 0.05), without significant differences for time in hypoglycemia. Standard deviation, coefficient of variation, and total power of glycemia were significantly higher in the T2D group than Control group (all p < 0.05). The oscillatory patterns were significantly different between groups (p = 0.032): the control group was mainly distributed at 2–3 and 6 days, whereas the T2D group showed a more homogeneous distribution across 2–3-to-6 days. Conclusions: The predictive model of glycemia showed that it is possible to accurately predict hyper- and hypo-glycemia events. Thus, T2D patients exhibit specific oscillatory patterns of glycemic control, which are possible to predict. These findings may help to improve the treatment of DM by considering the individual oscillatory patterns of patients.

Abstract INTRODUCTION: This study reports the first occurrence of Psammolestes tertius (Hemiptera, Reduviidae, Triatominae) in the state of Sergipe, Brazil. METHODS: In 2020, 95 specimens were collected from the municipality of Porto da Folha, Sergipe, Brazil. RESULTS: This finding expands the geographical distribution of the species from 15 states in Brazil to 16 and increases the biodiversity of triatomines in the state of Sergipe. CONCLUSIONS: The presence of P. tertius in the state of Sergipe demonstrated a wider distribution of this species in northeastern Brazil.

Abstract Background: Chronic heart failure (CHF) is a global health problem. Increased sympathetic outflow, cardiac arrhythmogenesis and irregular breathing patterns have all been associated with poor outcomes in CHF. Several studies showed that activation of the renin-angiotensin system (RAS) play a key role in CHF pathophysiology. Interestingly, potassium (K+) supplemented diets showed promising results in normalizing RAS axis and autonomic dysfunction in vascular diseases, lowering cardiovascular risk. Whether subtle increases in dietary K+ consumption may exert similar effects in CHF has not been previously tested. Accordingly, we aimed to evaluate the effects of dietary K+ supplementation on cardiorespiratory alterations in rats with CHF. Methods: Adult male Sprague–Dawley rats underwent volume overload to induce non-ischemic CHF. Animals were randomly allocated to normal chow diet (CHF group) or supplemented K+ diet (CHF+K+ group) for 6 weeks. Cardiac arrhythmogenesis, sympathetic outflow, baroreflex sensitivity, breathing disorders, chemoreflex function, respiratory– cardiovascular coupling and cardiac function were evaluated. Results: Compared to normal chow diet, K+ supplemented diet in CHF significantly reduced arrhythmia incidence (67.8 ± 15.1 vs. 31.0 ± 3.7 events/hour, CHF vs. CHF+K+), decreased cardiac sympathetic tone (ΔHR to propranolol: - 97.4 ± 9.4 vs. - 60.8 ± 8.3 bpm, CHF vs. CHF+K+), restored baroreflex function and attenuated irregular breathing patterns. Additionally, supplementation of the diet with K+ restores normal central respiratory chemoreflex drive and abrogates pathological cardio-respiratory coupling in CHF rats being the outcome an improved cardiac function. Conclusion: Our findings support that dietary K+ supplementation in non-ischemic CHF alleviate cardiorespiratory dysfunction.

Abstract Background: Deep breathing (DB) and handgrip (HG) exercise -with and without circulatory occlusion (OC) in muscle-, have been shown to have beneficial effects on cardiovascular function; however, the combination of these maneuvers on heart rate (HR) and cardiac sympathovagal balance have not been previously investigated. Therefore, the aim of the present study was to evaluate the effect of simultaneous DB, HG, and OC maneuvers on the sympathovagal balance in healthy women and men subjects. Methods and results: Electrocardiogram and ventilation were measured in 20 healthy subjects (Women: n = 10; age = 27 ± 4 years; weight = 67.1 ± 8.4 kg; and height = 1.6 ± 0.1 m. Men: n = 10; age = 27 ± 3 years; weight = 77.5 ± 10.1 kg; and height = 1.7 ± 0.1 m) at baseline and during DB, DB + HG, or DB + HG + OC protocols. Heart rate (HR) and respiratory rate were continuously recorded, and spectral analysis of heart rate variability (HRV) were calculated to indirectly estimate cardiac autonomic function. Men and women showed similar HR responses to DB, DB + HG and DB + HG + OC. Men exhibited a significant HR decrease following DB + HG + OC protocol which was accompanied by an improvement in cardiac autonomic control evidenced by spectral changes in HRV towards parasympathetic predominance (HRV High frequency: 83.95 ± 1.45 vs. 81.87 ± 1.50 n.u., DB + HG + OC vs. base-line; p < 0.05). In women, there was a marked decrease in HR after completion of both DB + HG and DB + HG + OC tests which was accompanied by a significant increase in cardiac vagal tone (HRV High frequency: 85.29 ± 1.19 vs. 77.93 ± 0.92 n.u., DB + HG vs. baseline; p < 0.05). No adverse effects or discomfort were reported by men or women during experimental procedures. Independent of sex, combination of DB, HG, and OC was tolerable and resulted in decreases in resting HR and elevations in cardiac parasympathetic tone. Conclusions: These data indicate that combined DB, HG and OC are effective in altering cardiac sympathovagal balance and reducing resting HR in healthy men and women.

A negligência dentária é definida como a falta intencional do responsável pela criança na procura e manutenção do tratamento necessário para garantir um nível de saúde oral essencial para a função adequada, livre de dor e infeção. Neste sentido, pretendemos esclarecer, de acordo com a literatura científica atual, os indícios clínicos para a identificação de negligência dentária em crianças. Após pesquisa em bases de dados e motores de busca, com as palavras-chave "child", "dental", "neglect", entre 1996 e 2016, os resultados revelaram que a identificação desta condição requer, não só a obtenção de uma história clínica detalhada e de dados clínicos que evidenciem claramente a falta de cuidados na saúde oral como também a investigação dos determinantes sociais e parentais em que a criança se insere. Assim, inserir o médico dentista nas equipas de análise nos casos de suspeita revelou-se indispensável para o despiste desta e outras situações de abuso.

Dental neglect is defined as an intentional failure of the caretaker in the pursuit and continuity of necessary treatment to achieve an oral health that allows adequate function, free from pain and infection. We intend to clarify, according to the current scientific literature, the clinical indications for the identification of dental neglect in children. After the search in databases and search engines with the keywords "child", "dental" and "neglect", between 1996 and 2016, the results revealed that identifying this condition requires not only a detailed clinical history and clinical data that clearly show the lack of oral health care but also investigating the social and parental determinants in which the child is involved. Thus, inserting the dentist in teams of analysis in case of suspicion proves to be indispensable for the detection of this and other situations of abuse.

Introduction: Heart rate variability and resting metabolic rate are commonly to assess athlete's physiological status and energy requirements. Exercise-induced dehydration can reach up to 5% of body mass per hour. Consequently, dehydration may have a profound physiological effect on human's homeostasis. Objectives: To compare the effects of dehydration and rehydration after exercise on heart rate variability and resting metabolic rate in college athletes. Methods: 14 college athletes were divided into a dehydration group (n=7) and a rehydration group (n=7), both submitted to basal (T1) heart rate variability and resting metabolic rate measurements. After basal measurements both groups were actively dehydrated (-3.4 ± 0.4% of body mass for both groups). Afterwards, dehydration group rested, while rehydration group receive a fluid intake (during a 3 h period) equivalent to 150% of body mass loss achieved during active dehydration. Four hours after active dehydration heart rate variability and resting metabolic rate were re-assessed (T2). Results: At T2 both rehydration group (+13%) and dehydration group (+30%) achieve a significant (p<0.05) increase in resting metabolic rate, however, only dehydration group ..showed a significant reduction in heart rate variability. More so, the change in resting metabolic rate was significantly higher in dehydration group compared to rehydration group. Discussion: Hydric homeostasis after exercise affects resting metabolic rate and heart rate variability, highlighting the necessity to control hydration state before resting metabolic rate and heart rate variability assessment.

Introducción: La variabilidad del ritmo cardiaco y la tasa metabólica basal se utilizan en evaluaciones de deportistas. La deshidratación por ejercicio puede conducir a pérdidas de hasta 5% de la masa corporal. En consecuencia, la deshidratación produce un profundo efecto sobre la homeostasis humana. Objetivos: Comparar los efectos de la deshidratación y la rehidratación después del ejercicio en la variabilidad del ritmo cardíaco y la tasa metabólica basal. Métodos: 14 atletas universitarios fueron divididos en un grupo de deshidratación (n=7) y un grupo de rehidratación (n=7), ambos fueron sometidos mediciones basales (Tiempo 1) de variabilidad del ritmo cardíaco y tasa metabólica basal. Después de las mediciones basales, ambos grupos se deshidrataron activamente (-3,4 ± 0,4% masa corporal). Posteriormente, el grupo de deshidratación descansado, mientras que el grupo de rehidratación recibió agua equivalente al 150% de la masa pérdida. Cuatro horas después de la deshidratación se re-evaluó la variabilidad del ritmo cardíaco y tasa metabólica (Tiempo 2). Resultados: El grupo de rehidratación (+13%) y el de deshidratación (+30%) lograron un aumento significativo en la tasa metabólica basal (p <0.05), sin embargo, solo el grupo de deshidratación muestran cambios significativos en la variabilidad del ritmo cardíaco (es decir, disminuye). El cambio en la tasa metabólica basal fue significativamente mayor en el grupo deshidratación comparado con el grupo de rehidratación. Discusión: la homeostasis hídrica después del ejercicio afecta la tasa metabólica basal y la variabilidad del ritmo cardíaco, destacando la necesidad de controlar el estado de hidratación antes de las evaluaciones de la tasa metabólica basal y variabilidad del ritmo cardíaco.

RESUMO INTRODUÇÃO: A execução de tratamentos odontológicos em pacientes pediátricos que apresentam alterações comportamentais constitui frequentemente um grande desafio clínico para o odontopediatra. Dependendo da maturidade emocional dos pacientes e de suas habilidades físicas, psicológicas e mentais, as técnicas de controle de comportamento usuais podem não oferecer a eficácia e a segurança adequadas à realização dos procedimentos dentários. Nestas circunstâncias, podem ser necessários métodos alternativos e mais invasivos, como a sedação consciente e a anestesia geral. Neste trabalho comparam-se as indicações e contra-indicações de sedação consciente e anestesia geral em odontopediatria. MÉTODO: A revisão da literatura foi realizada através dos motores de pesquisa MEDLINE/PubMed, Science Direct e B-ON, entre abril e junho de 2013, com uma limitação temporal de cinco anos e as seguintes palavras-chave: sedação consciente, a anestesia geral, odontopediatria e diretrizes. RESULTADOS: A sedação consciente é recomendada para pacientes ansiosos, com "medo de dentista e de agulhas", para pacientes que apresentam um maior reflexo do vómito e também para pacientes com necessidades especiais, mas capazes de comunicação. Por outro lado, a anestesia geral é recomendada para pacientes com idade inferior a quatro anos que não colaboram, para respiradores orais, para crianças ASA III ou superior e para crianças que não se comunicam. CONCLUSÕES: Cada técnica deve ser escolhida de acordo com as características do paciente. Apesar da anestesia geral e da sedação consciente introduzirem benefícios no atendimento dentário do paciente infantil, estas não devem ser consideradas como técnicas de intervenção prioritária no controle comportamental. O conhecimento prévio das indicações e contraindicações destas técnicas permitem ao odontopediatra proporcionar um maior nível de qualidade no atendimento dentário, assegurando a maior segurança e o menor desconforto para os seus pacientes jovens.

INTRODUCTION: Performing dental treatments on pediatric patients who present behavioral problems is usually a great clinical challenge. Depending on the patients’ emotional maturity and their physical, psychological and mental skills, the usual behavior control techniques may not offer adequate efficacy and safety when dental procedures are being carried out. In these circumstances, alternative and more invasive methods such as conscious sedation and general anesthesia may become necessary. OBJECTIVE: To compare the indications and contraindications of conscious sedation and general anesthesia in pediatric dentistry. METHOD: Literature research undertaken through the MEDLINE/Pubmed, Science Direct and B-on search engines between April and June 2013 using a 5 year time frame and the following keywords: conscious sedation, general anesthesia, pediatric dentistry and guidelines. RESULTS: Conscious sedation is recommended to anxious patients who have dental and needle phobia, to patients that present an increased vomiting reflex and also to patients with special needs but capable of communicating. General anesthesia is indicated for non-cooperating patients under the age of four, in mouth breathers, in children ASA III or higher and in pediatric patients who do not communicate. CONCLUSIONS: Each technique must be selected according to the characteristics showed by patient. Although conscious sedation and general anesthesia introduce benefits to pediatric dentistry, they should not be regarded as priority intervention techniques for behavior control. The pediatric dentist’s previous knowledge of these techniques provides a better level of dental care quality as well as more safety and less discomfort for their patients.

Produção de artigos científicos do esporte em países da América do Sul (n = 11) foi estudada entre 1970-2012 utilizando: todos os dados de citações do ISI Web of Knowledge. Foram avaliados: número de artigos publicados; número de artigos publicados/número de pessoas em ciência e tecnologia (no.pub/no.pes); assuntos mais estudados; predominância de instituições publicas ou privadas; fator de impacto (FI); citações média por documento por país no ISIweb; frequência de artigos publicados por periódicos por país. Brasil teve o maior número de artigos publicados, seguido pela Argentina. Bolívia mostra o mais elevado no.pub/no.pes, seguido pela Peru. Os temas mais estudados foram: ortopedia, fisiologia e reabilitação. As instituições públicas que apresentam maior número de artigos publicados. Peru e Bolívia foram os únicos países com uma média IF de 2 ou superior. Citação média foi maior no Peru (maior coeficiente de variação). Nas conclusões, nossos resultados mostram que, na maioria dos países, a sua taxa de artigos publicados aumenta ao longo do tempo. Isso pode estar relacionado com o novo governo e políticas institucionais. No entanto, a produção foi baixa em comparação com outras áreas.

Sports science article publication in South American countries (n=11) was studied between 1970-2012, using all citation database of ISI Web of Knowledge. We evaluated: number of published articles; the number of publications divided by the number of people in science and technology (number pub/number peo); the top incidence of research subjects; public or private institutional predominance; impact factor (IF); average citations per document per country; and frequency of published articles per journals per country. Brazil showed the highest number of published articles, followed by Argentina. Bolivia showed the highest number pub/number peo, followed by Peru. Most studied themes were physiology, orthopedic and rehabilitation. Public institutions showed a higher published articles number than did private institutions. Peru and Bolivia were the only countries with a mean IF of 2 or higher. Average citation was higher in Peru (higher coefficient variation). In conclusions, our results show that, in most South American countries, their published articles rate has increased over time. This could be related to new government and institutional policies. However, production was low compared with other areas of science.

Esto puede ser relacionado con nuevas políticas gubernamentales e institucionales. Sin embargo, la producción es baja comparado con otras áreas.

Background: Physical inactivity is a major risk factor and aerobic exercise is protective for cardiovascular health. Aim: To determine the effects of aerobic exercise on systolic and diastolic blood pressure in children, adolescents and adults. Material and Methods: We studied 13 children aged 10 ± 1.9 years, 13 adolescents aged 14.3 ± 1.5 and 55 adults aged 41 ± 11.5 years. Participants completed 60 minutes of aerobic exercise in one session. Body weight, systolic and diastolic blood pressure, and resting heart rate were measured before and after the exercise period. Results: Adult men and women experienced a significant decrease in body weight after exercise (-8 and -6%, respectively). No significant changes in weight were observed in children and adolescents. After exercise systolic and diastolic blood pressure decreased significantly in children (-8.3 and -5.4% respectively), adolescents (-7.6 and -8.4% respectively) and adults (-7 and -5.1% respectively). Conclusions: A 60 minute period of aerobic exercise is associated with a reduction in blood pressure in children, adolescents and adults.

OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78% vs. 58% of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth) essentially reflects data obtained from treated teeth, for which 91% of children with Down syndrome had never had a tooth treated vs. 67% of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

O interesse comercial pela atemóia é crescente no Brasil. Sabe-se que é uma fruta com vida útil bastante limitada. O objetivo do presente trabalho foi avaliar a qualidade pós-colheita de atemóias cv. Gefner submetidas a embalagens e armazenamento refrigerado. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 3 x 5 (três embalagens: controle (sem embalagem); embalados individualmente com filme de PVC; colocados em bandejas de poliestireno envolvidas com filme de PVC em cinco tempos de armazenamento), com três repetições. Avaliou-se a perda de massa fresca; coloração da casca e da polpa; Sólidos Solúveis (SS); Acidez Total Titulável (ATT); vitamina C; pH da polpa e atividade de água por ocasião da colheita, a cada três dias de armazenamento. O uso da atmosfera modificada não influenciou na coloração da casca, mas preservou a luminosidade da polpa e reduziu a perda de massa fresca dos frutos. Os teores de SS e ATT aumentaram durante o armazenamento, e foram maiores nos frutos sem embalagens, assim como o teor de vitamina C. O uso de refrigeração foi eficiente na conservação da atemóias 'Gefner', que, após 15 dias de armazenamento ainda apresentavam qualidade para serem comercializados.

Despite the increasing commercial interest in atemoya in Brazil, this fruit has a very limited shelf-life. The present work intended to evaluate the storage of atemoya cv. Gefner under different packing systems and cold storage periods. A factorial of 3 x 5 completely randomized design was used (three packing systems: control (unpacked), individually packed with PVC films, and placed in polyester trays wrapped in PVC film for five different storage periods), with three replicates. Weight loss, skin and pulp color, Soluble Solids (SS), Total Tritable Acidity (TTA), vitamin C, pulp pH, and water activity at harvest were recorded every three days of storage. Modified atmosphere did not influence the skin color, but it preserved the pulp brightness and reduced weight loss of the unpacked fruits. SS and TTA levels increased during the storage of unpacked fruits as did the vitamin C contents. Cold storage was efficient for the atemoya preservation, which presented good appearance after 15 days of storage.
