Abstract The aim of this multicenter study was to explore the early-life sugar consumption and dietary practices in Latin America as well as to investigate the association between breastfeeding duration and the age at which foods and beverages with added sugars are introduced. A cross-sectional study was conducted with 805 1- to 3-year-old children from 10 Latin American countries, as a complementary study to the Research Observatory for Dental Caries of the Latin American Region (OICAL). A Food Frequency Questionnaire previously tested in different countries was applied to children’s mothers and data on breastfeeding and age at introduction of sugary foods and beverages was collected. Statistical analysis included the Kruskal-Wallis test and Poisson regression with robust variance, with the calculation of crude and adjusted mean ratios (MR) and 95% of confidence intervals (CI). The average age at introduction of sugary foods and beverages was 10.1 months (95%CI 9.7–10.4) and 9.6 (95%CI 9.2–9.9) months, respectively, with a significant variation between countries (p < 0.001). The average daily frequency of sugary foods-beverages was 3.3 times per day (95%CI 3.1–3.5) and varied significantly between countries (p = 0.004). Breastfeeding duration of over six months was associated with an increase in the age of introduction of sweet drinks (16%; MR 1.16; 95%CI 1.05–1.28) and foods (21%; MR 1.21; 95%CI 1.10–1.33). In conclusion, most children from vulnerable settings in Latin America start consuming sugary products in the first year of life and a high frequency of consumption was reported through early childhood. Additionally, breastfeeding contributes to a delay in the introduction of sugary products.

RESUMO: Buscamos por um impacto positivo de utilidade nas espécies invasoras como Pterygoplichthys spp. Foi avaliado o nível ótimo de substituição da farinha de sardinha (SM) pela farinha de Pterygoplichthys spp. (PML) em dietas práticas para tilápia do Nilo (Oreochromis niloticus). Foram utilizadas seis dietas experimentais; 50% PLM-50% SM, 60% PLM-40% SM, 70% PLM-30% SM, 80% PLM-20% SM, 90% PLM-10% SM e 100% PLM-0% SM. Em sistema de recirculação foram colocados 270 filhotes de tilápia machos (0.7 ± 0.1 g). As dietas foram triplicadas, o experimento durou 56 dias com amostragem a cada 14 dias, não houve diferença estatística para o crescimento. No final do experimento, foram determinados SGR, ADG, CF, WG, DFI, FCR e PER, não encontrando diferenças significativas (P> 0,05), embora tenha havido uma tendência indicando maior WG e PER na dieta 90% PLM-10% SM (93,56 ± 0,43% e 8,44 ± 1,18 g). A sobrevida foi superior a 90%, sem diferenças significativas. Além disso, não houve diferenças significativas na composição proximal de todo o peixe, enquanto o aparente coeficiente de digestibilidade de proteínas (81-90%) e lipídios (87-93%) também não mostrou diferenças significativas. Podemos concluir que o uso de 100% de farinha de Pterygoplichthys spp. pode substituir 100% de farinha de sardinha na alimentação de jovens O. niloticus sem afetar a sobrevivência, o crescimento, a composição química e a digestibilidade aparente dos nutrientes.

ABSTRACT: We search for positive utility impact on the invasive species Pterygoplichthys spp. The optimal level of replacement of sardine meal (SM) by Pterygoplichthys spp. meal (PLM) in practical feeds for fry of Nile tilapia (Oreochromis niloticus) was evaluated. We evaluated six experimental diets: 50% PLM-50% SM, 60% PLM-40% SM, 70% PLM-30% SM, 80% PLM-20% SM, 90% PLM-10% SM and 100% PLM-0% SM. In a recirculation system, 270 sex-reversed tilapia fry were used (0.7 ± 0.1 g). Diets were administered in triplicate and the experiment lasted 56 days with sampling every 14 days. There were no statistical differences in growth. At the end of the experiment, the SGR, ADG, CF, WG, DFI, FCR and PER were determined without significant differences (P > 0.05) between treatments, but there was a tendency that could indicated higher WG and PER in the 90% PLM-10% SM treatment (93.56 ± 0.43% and 8.44 ± 1.18 g, respectively). All survival rates were higher than 90% with no significant differences. Additionally, there were no statistical differences in the chemical composition of the whole fish, while apparent digestibility coefficients of protein (81-90%) and lipids (87-93%) also showed no significant differences. We concluded that 100% PLM can replace 100% SM in feeding fry of O. niloticus without affecting their survival, growth or chemical composition or the apparent digestibility of nutrients.

Abstract Bay snook (Petenia splendida) is a carnivorous cichlid species with excellent economic value in Southeast Mexico. Although this species presents an excellent potential for commercial aquaculture, the information about its nutritional, physiological, and reproductive metabolic pathways is meager. The current study focuses on the expression of glucose transporter 2 (glut2) in embryos and larvae at 5, 10, 15-, 20-, 25-, and 30-days post-hatch (dph) and in the liver, intestine, kidney, muscle, heart, testicle, gill, stomach, pancreas, and brain of adult fish. The partial sequence of glut2 was obtained, and specific qPCR primers were designed. In embryos, the expression was lower compared to larvae at 5, 15, and 20 dph. The highest expression in larvae occurred at 20 dph and the lowest at 25 and 30 dph. Maximum expression levels in adults occurred in the liver and intestine. Our results show that glut2 is expressed differentially across tissues of adult bay snook, and it fluctuates during larval development.

Resumen La mojarra tenguayaca (Petenia splendida) es una especie de cíclido carnívoro con excelente valor comercial en el sureste de México. A pesar de su potencial para la acuicultura, existe muy poca información sobre sus rutas metabólicas relacionadas con su nutrición, fisiología y reproducción. El presente estudio se enfoca en la expresión del transportador de glucosa (glut2) en embriones y larvas de 5, 10, 15, 20, 25 y 30 días post eclosión (dph) y en el hígado, intestino, riñón, músculo, corazón, testículo, branquias, estómago, páncreas y cerebro en peces adultos. Se diseñaron cebadores de qPCR específicos para glut2. La expresión en los embriones fue menor que en larvas a los 5, 15 y 20 dph. La expresión máxima en larvas se observó a los 20 dph y la mínima a los 25 y 30 dph. La expresión más alta en los adultos ocurrió en el hígado y el intestino. Nuestros resultados muestran que el gen glut2 se expresa de manera diferencial en los tejidos de adultos de la mojarra tenguayaca y su expresión fluctúa durante el desarrollo larvario.

ABSTRACT Objective: To cross-culturally adapt into the Brazilian Portuguese and evaluate the psychometric properties of an instrument for assessing the satisfaction of parents/guardians regarding their sons’/daughters’ orthodontic treatment. Methods: Translations of the instrument from English, pre-test and evaluation of validity and reliability of the Brazilian Portuguese version were performed. The questionnaire has 25 items distributed across 3 subscales (process, psychosocial effect and outcome). Eighty-three parents/guardians of children/adolescents who had completed orthodontic treatment participated. Descriptive statistics and floor and ceiling effects were calculated. Internal consistency, stability (interval of three weeks), convergent construct validity and discriminant construct validity were determined. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) assessed dimensionality. Results: Among the 83 parents/guardians, 58 (69.9%) were mothers and 25 (30.1%) were fathers of children/adolescents. In the questionnaire’s total score and the three subscales scores, an acceptable percentage (≤15%) of participants achieved the maximum score (ceiling effect). In the total questionnaire score and in the three subscales scores, no participant achieved the minimum score (floor effect). Cronbach’s α coefficient for the total score was 0.72 (internal consistency). Intra-class correlation coefficient for the total score was 0.71 (stability). The questionnaire’s total score presented large Pearson correlation coefficient (>0.50) with the three subscales too (construct validity). Female parents/guardians had significantly higher scores in the psychosocial effect (p=0.013) and in the treatment outcome (p=0.037) subscales, compared to male parents/guardians (discriminant validity). EFA and CFA confirmed dimensionality in a three-factor solution. Conclusions: The final obtained version is valid and reliable to be used in Brazilian populations.

RESUMO Objetivo: Adaptar transculturalmente para a língua portuguesa do Brasil e avaliar as propriedades psicométricas de um questionário que avalia a satisfação de pais e responsáveis com relação ao tratamento ortodôntico recebido por seus filhos. Métodos: Tradução do questionário em inglês, pré-teste e avaliação da validade e confiabilidade da versão em português obtida. O questionário consistiu de 25 itens distribuídos em três subescalas (processo durante o tratamento, efeito psicossocial e resultado geral do tratamento). Participaram 83 pais/responsáveis de crianças/adolescentes que concluíram o tratamento ortodôntico. Estatística descritiva foi realizada e foi calculado valor máximo e valor mínimo. Foram determinadas a consistência interna, a estabilidade (intervalo de três semanas), a validade de constructo convergente e a validade de constructo discriminante. A análise fatorial exploratória (AFE) e a análise fatorial confirmatória (AFC) avaliaram a dimensionalidade. Resultados: dos 83 pais/responsáveis que participaram do estudo, 58 (69,9%) eram mães e 25 (30,1%) eram pais das crianças/adolescentes. No escore total do questionário e no escore das três subescalas, uma porcentagem aceitável (≤15%) dos participantes atingiu o escore máximo (ceiling effect). No escore total do questionário e no escore das três subescalas, nenhum participante atingiu o escore mínimo (floor effect). O coeficiente α de Cronbach para o escore total foi 0,72 (consistência interna). O coeficiente de correlação intraclasse para o escore total foi 0,71 (estabilidade). O escore total do questionário apresentou um coeficiente de correlação de Person alto (>0,50) com as três subescalas (validade de constructo). Pais/responsáveis do sexo feminino apresentaram escores significativamente maiores nas subescalas efeito psicossocial (p=0,013) e desfecho do tratamento (p=0,037), em comparação aos pais/responsáveis do sexo masculino (validade discriminante). AFE e AFC confirmaram a dimensionalidade em uma solução de três fatores. Conclusões: A versão do questionário obtida no presente estudo mostrou-se válida e confiável para o uso na população brasileira.

RESUMEN El trasplante de hígado es el principal tratamiento para la enfermedad hepática en etapa terminal. El cuidado postoperatorio es un gran desafío para disminuir la morbimortalidad en los pacientes. En este sentido, el manejo en la UCI hepática permite manejo hemodinámico, monitoreo de coagulación, soporte renal, alteraciones electrolíticas, soporte respiratorio y destete temprano de ventilación mecánica y evaluación del injerto hepático. Objetivo: El presente estudio muestra los resultados del manejo de pacientes trasplantados de hígado en 20 años de experiencia en un centro de trasplante en un país de ingresos bajos a medios. Materiales y métodos: Se revisaron las historias clínicas de 273 pacientes adultos en UCI en el posoperatorio inmediato de trasplante hepático, desde el 20 de marzo de 2000 hasta el 30 de noviembre de 2020, incluyendo el efecto de la pandemia provocada por el COVID-19. Se excluyeron los pacientes con trasplante de hígado-riñón, retrasplantados, SPLIT y dominó. Resultados: La etiología más frecuente para LTx fue NASH (35%), la edad promedio fue de 49 años, MELD Score varió 15 - 20 (47,5%), 21 - 30 (46%) > 30 (6,2%). Estancia pretrasplante en UCI 7%, estancia media en UCI: 7,8 días. Admisión media APACHE: 14,9 puntos. Extubación weaning del 91,8% de los pacientes en UCI y Fast Track en el 8,2%. La complicación respiratoria más frecuente fue atelectasia 56,3%, neumonía (31,3%); FRA 1 (60,9%) y 11,1% con soporte de hemodiálisis (FRA 3). Inmunosupresión: Tacrolimus (8,9%). La mortalidad postoperatoria en la UCI fue del 6,2%. Conclusiones: El manejo del trasplante hepático en UCI es fundamental para lograr resultados óptimos en pacientes que presentan enfermedad hepática avanzada y requieren soporte vital avanzado en el postoperatorio inmediato y así optimizar la supervivencia del injerto.

ABSTRACT Liver transplantation is the major treatment for end-stage liver disease. Postoperative care is a great challenge to reduce morbidity and mortality in patients. In this sense, management in the liver ICU allows hemodynamic management, coagulation monitoring, renal support, electrolyte disturbances, respiratory support and early weaning from mechanical ventilation and evaluation of the liver graft. Objective: The present study shows the results of the management of liver transplant patients in 20 years of experience in a transplant center in a low- to middle-income country. Materials and methods: The medical records of 273 adult patients in the ICU in the immediate postoperative liver transplant were reviewed, from March 20, 2000 to November 30, 2020, including the effect of the pandemic caused by COVID-19. Liver-kidney, retransplanted, SPLIT, and domino transplant patients were excluded. Results: The most frequent etiology for LTx was NASH (35%), the mean age was 49 years, MELD Score ranged 15 - 20 (47.5%), 21 - 30 (46%) > 30 (6.2%). ICU pre transplant stay 7%, average ICU stay: 7.8 days. APACHE average admission: 14.9 points. Weaning extubation of 91.8% patients in ICU and Fast Track in 8.2%. The most frequent respiratory complication was atelectasis 56.3%, pneumonia (31.3%); AKI 1 (60.9%), and 11.1% with hemodyalisis support (AKI3). Immunosuppression: Tacrolimus (8.9%). Post-operative ICU mortality was 6.2%. Conclusions: The management of liver transplantation in the ICU is essential to achieve optimal results in patients who present advanced liver disease and require advanced life support in the immediate postoperative period and thus optimize graft survival.

ABSTRACT In the Southeast of Mexico, there are many native cichlids with commercial interest such as redhead cichlid (Vieja melanurus) and twoband cichlid (V. bifasciata), which have a great local demand and excellent meat quality. However, it is necessary to implement their culture based on nutrition studies and digestive biochemistry. This study’s objective was to characterize these two cichlids’ digestive proteases (pH, temperature, and inhibitors) through biochemistry techniques. Results showed that V. melanurus and V. bifasciata have a digestive capacity analogous to other omnivore fishes, where the optimal pH values of stomach proteases (4 and 2, respectively) and intestinal proteases (6 and 12, respectively), the optimal temperature of acid (35°C and 55°C, respectively) and alkaline proteases (45°C and 55°C, respectively) are quite similar. Both species presented high thermal and pH stabilities. Inhibition showed that V. melanurus is more sensitive to specific inhibitors for alkaline proteases than V. bifasciata. In conclusion, V. bisfasciata and V. melanurus have different digestive protease patterns. Both species can hydrolyze different protein ingredients to formulate a specific diet. Nevertheless, V. bifasciata is more resistant to the presence of inhibitors, which allow it to include vegetable proteins in its diet.

RESUMEN En el sureste de México, existen muchas especies de cíclidos nativos de interés comercial como el cíclido rojo (Vieja melanurus) y el cíclido de dos bandas (V. bifasciata), los cuales tienen una gran demanda local y tienen una excelente calidad de carne; sin embargo, es necesario implementar su cultivo con base en estudios de nutrición y bioquímica digestiva. El objetivo de este estudio fue caracterizar las proteasas digestivas (pH, temperatura e inhibidores) de estos dos cíclidos nativos mediante técnicas bioquímicas. Los resultados mostraron que V. melanurus y V. bifasciata tienen una capacidad digestiva similar a otros peces omnívoros, donde los valores óptimos de pH de proteasas estomacales (4 y 2, respectivamente) e intestinales (6 y 12, respectivamente), la temperatura óptima de proteasas ácidas (35°C y 55°C, respectivamente) y alcalinas (45°C y 55°C, respectivamente) son muy parecidas. Ambas especies presentaron alta estabilidad térmica y de pH. La inhibición mostró que V. melanurus es más sensible a inhibidores específicos de proteasas alcalinas que V. bifasciata. En conclusión, V. bisfasciata y V. melanurus tienen diferentes patrones de proteasas digestivas, pero ambas especies pueden hidrolizar diversos ingredientes proteicos para formular dietas específicas; sin embargo, V. bifasciata es más resistente a la presencia de inhibidores, lo que permitiría incluir proteínas vegetales en su dieta.

Abstract: This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3–5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach’s alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.

Resumen: En | Texto: En | PDF: En

Abstract Robust epidemiological data allow for logical interventions taken in the interest of public health. Dental caries is a major public health problem driven by increased sugar consumption and various biological, behavioral, and psychosocial factors, and is known to strongly affect an individual’s quality of life. This study aims to critically review epidemiological data on the prevalence of dental caries in Latin American and Caribbean countries (LACC) and its impact on the oral health-related quality of life (OHRQoL) of the population. Although the majority of national surveys did not include all age groups and several countries reported a reduction in the prevalence of cavitated carious lesions, most nations still exhibited a high burden of decayed teeth. OHRQoL evaluation was limited to children and older adults only, and was not included in any national survey. Study heterogeneity and methodological issues hindered comparison of evidence between studies and over time, and updating national level data on caries prevalence and its impact on OHRQoL should be prioritized in LACCs.

Resumen: En Es | Texto: En Es | PDF: En | PDF: Es

The case of a 32 years old male patient who since age 17 has experienced constrictive headaches of several minutes duration, triggered by physical effort is reported. For the last seven years there, he has presented a progressive cognitive decline cognitive, and marked personality changes, having become extremely dependent even for conducting elemental activities. At the age of 27, he experienced total left hemiplegia from which he completely recovered in two weeks. He also shows severe confusional states and child-like behavior. Laboratory tests ruled out heart disease, atherosclerosis and systemic autoimmune diseases. Brain neuroimaging tests (CT, Angio - TEM and contrasted cerebral MRI) revealed the occurrence of six cerebral infarcts, in subacute and chronic stages, severe stenosis of the anterior cerebral arteries, and presence of microaneurysm in the M segment of the left middle brain artery. A limitation of this report is the absence of a study with digital angiography, due to economic difficulties. In short, the case of a patient with chronic headache associated with progressive dementia is presented, with neuroimaging and neuropsychological tests that support the diagnosis of of cognitive impairment associated with Moyamoya disease.

Se reporta el caso de un paciente de 32 años de edad que desde los 17 y hasta la actualidad, ha experimentado cefaleas constrictivas de minutos de duración, desencadenadas por actividad o esfuerzos físicos. En los últimos siete años ha presentado progresiva declinación cognitiva y cambios acentuados de personalidad con creciente dependencia para el desarrollo de actividades elementales. A los 27 años desarrolló hemiplejía izquierda total con recuperación completa en dos semanas. Muestra asimismo episodios de estado confusional severo y conducta infantil. Los exámenes de laboratorio descartaron cardiopatía, ateroesclerosis y enfermedades autoinmunes sistémicas en el paciente. Estudios neuroimagenológicos del cerebro (TAC, Angio - TEM y RM cerebralcontrastada) pusieron en evidencia seis infartos cerebrales, en estadios subagudos y crónicos, severa estenosis de las arterias cerebrales anteriores y presencia de un microaneurisma en el segmento M de la arteria cerebral media izquierda. Una limitación del presente reporte es la ausencia de estudios con angiografía digital, debida a dificultades económicas. En conclusión, el caso corresponde a un paciente con cefalea crónica asociada a demencia progresiva, en el que estudios de neuroimágenes y pruebas neuropsicológicas sustentan el diagnóstico de deterioro cognitivo asociado a la enfermedad de Moyamoya.

Resumen: En Es | Texto: En Es | PDF: En | PDF: Es

Abstract Introduction: There is no consensus about if patients with EUS-guided drainage (EUS-GD) of pancreatic pseudocyst (PPC) could be discharged the same day or if the patient must stay at least one night in hospital. The aim was to report adverse events rate in the first 24 h after the procedure of patients with PPC treated by EUS-GD. Materials and Methods: A retrospective analysis of data obtained prospectively was conducted. Patients with PPC were included in the study. EUS-GD was using two double pigtail plastic stents (7F and 4 cm). Results: A total of 31 procedures in 29 patients with PPC were analyzed. There were 16 (55.2%) men with a mean ± SD age of 42.5 ± 14.5 years. The endoscopic drainage was performed through transgastric in 23/29 (79.3%) patients and transduodenal in 6/29 (17.2%) patients. Technical success was 100%, clinical success was 27/29 (93.1%), and three (10.3%) patients had recurrence. In total, 5/31 (16.1%) procedures have adverse events. One patient had stent migration after 24-month follow-up, two patients had infection of PPC after the punctuation (at day 4 and 5 after procedure), and two patients who bled during endoscopic drainage (one of them was successfully treated endoscopically with clips and the second required surgery). Conclusion: There is not a clear reason because patients with PPC and EUS-GD need for staying one night in hospital if was not any adverse event during the procedure.

Resumen Introducción: No hay consenso acerca de si los pacientes con pseudoquiste pancreático (PQP) con drenaje guiado por EUS (EUS-GD) podrían ser dados de alta el mismo día o si el paciente debe permanecer al menos una noche en el hospital. El objetivo fue informar la tasa de eventos adversos en las primeras 24 horas después del procedimiento. Material y métodos: Se realizó un análisis retrospectivo de datos obtenidos prospectivamente. Se incluyeron pacientes con PQP. Los EUS-GD utilizaron dos endoprótesis de plástico de doble cola de cochino (7F X 4 cm). Resultados: se analizaron un total de 31 procedimientos en 29 pacientes con PQP. Se incluyeron 16 (55.2%) hombres con una media ± DE de edad 42.5 ± 14.5 años. El drenaje se realizó por vía transgástrica en 23/29 pacientes (79,3%) y transduodenal en 6/29 pacientes (17,2%). El éxito técnico fue del 100%, el éxito clínico fue de 27/29 (93,1%) y 3 (10,3%) pacientes tuvieron recurrencia. En total, 5/31 (16.1%) procedimientos tuvieron eventos adversos. Un paciente tuvo una migración del stent después de 24 meses de seguimiento, dos pacientes tuvieron una infección del PQP después de la punción (en los días 4 y 5 después del procedimiento) y dos pacientes con hemorragia durante el drenaje endoscópico (uno de ellos se trató con éxito con endoscopia con clips y el segundo requirió cirugía). En conclusión: no hay una razón clara por la cual los pacientes con EUS-GD de PQP necesitan quedarse hospitalizados si no hubo ningún evento adverso durante el procedimiento.

Resumen El pejelagarto es una especie importante para la acuicultura en el sureste de México. Se han realizado varios estudios sobre nutrición y fisiología digestiva; sin embargo, el uso de microcápsulas para la alimentación de larvas que permitan mejorar el crecimiento y la supervivencia no ha sido realizado. En este sentido, se evaluaron cuatro alimentos microencapsulados en el crecimiento y supervivencia de larvas de pejelagarto (Atractosteus tropicus). Los tratamientos consistieron en cuatro dietas experimentales y un control: 1) Microcápsula con base en harina de pescado (DP), 2) Microcápsula con base en una combinación de harina de cerdo y pollo (Re), 3) Microcápsula con base en Nannochloropsis gaditana (Ng), 4) Microcápsula con base en un preparado enzimático, pancreatina (PE) el tratamiento control 5) Nauplios de Artemia (Na). Los resultados de las dietas indican que las larvas alimentadas con Nauplios (Na) tuvieron el mayor crecimiento y supervivencia (3.93 cm, 0.19 g y 82 % respectivamente). Mientras que en el caso de las larvas alimentadas con las dietas microencapsuladas, los mejores valores de supervivencia se observaron con las dietas Nannochloropsis gaditana (Ng) y preparado enzimático (PE) (20.0 y 19.2 % respectivamente). Nuestros resultados demuestran que el uso de microencapsulados para la alimentación de larvas de A. tropicus es factible, aunque se requieren más investigaciones para optimizar su diseño y elaboración para mejorar el crecimiento y supervivencia de los organismos.

Abstract Tropical gar is an important species for aquaculture purposes in Southeast Mexico. Several studies regarding nutrition and digestive physiology have been done; however, the use of microcapsules for larvae feeding to improve growth and survival has not been conducted. In this sense, four microencapsulated diets were evaluated with respect to the growth and survival of tropical gar Atractosteus tropicus larvae. The treatments consisted of four experimental diets and one control diet 1) fish meal, 2) a combination of pork and poultry meals, 3) Nannochloropsis gaditana meal, 4) enzyme preparation and the control treatment 5) Artemia nauplii. The evaluation indicated that the larvae fed the Artemia nauplii obtained the greatest growth and survival (3.93 cm, 0.19 g y 82 % respectively), which justifies a correct culture system operation. While larvae fed microencapsulated diets best values in survival were observed with diets Nannochloropsis gaditana and enzyme preparation (20.0 and 19.2 %). Our results showed that microencapsulated could be used to feed A. tropicus in feasibly form. However, more information concerning to optimize the design and manufacturing are required to improve the growth and survival of organisms. Rev. Biol. Trop. 66(3): 1298-1313. Epub 2018 September 01.

Resumen: En | Texto: En | PDF: En

Abstract: The aim of this study was to translate and cross-culturally adapt the condition-specific instrument Impact of Fixed Appliances Measure (IFAM), assessing its validity and reliability for use among Brazilian children/adolescents. The IFAM was translated, back-translated, cross-culturally adapted, and pilot-tested. The Brazilian version of the IFAM (B-IFAM) was tested on 161 10-to-18-year-old children/adolescents. Internal consistency was assessed using Cronbach's alpha (α) and test-retest reliability by intraclass correlation coefficients (ICC). Construct validity was conducted using Pearson correlation among the overall and subscales of the B-IFAM. Discriminant validity was evaluated by comparisons of B-IFAM's means and SD with children's/adolescents' sex (Student t-test). Internal consistency was 0.89 for overall score and 0.55–0.86 for subscales. ICC for test-retest reliability was 0.81 for overall score and 0.55–0.78 for subscales. The overall score of the B-IFAM presented large correlation coefficients with most subscales (r = 0.52–0.74), supporting construct validity. Discriminant validity demonstrated statistically significant difference in the overall score, aesthetics, and physical impact subscales among female and male children's/adolescents' (p < 0.05). In the conclusion, the B-IFAM overall score and some subscales demonstrated adequate psychometric properties regarding reliability and validity. The study achieved a specific-condition instrument feasible for use on Brazilian children/adolescents who wear fixed orthodontic appliances.

Resumen: En | Texto: En | PDF: En

Abstract The aim of the present study was to evaluate factors associated with sleep bruxism in five-year-old preschool children. A preschool-based cross-sectional study was conducted with 761 pairs of children and their parents/caregivers. Sleep bruxism was diagnosed using a questionnaire administered to the parents/caregivers, who also answered questionnaires addressing sociodemographic data and parent’s/caregiver’s sense of coherence. Clinical oral evaluations of the children to determine dental caries, traumatic dental injuries, malocclusion and tooth wear were performed by two researchers who had undergone a training exercise (interexaminer Kappa: 0.70 to 0.91; intraexaminer Kappa: 0.81 to 1.00). Descriptive analysis and logistic regression for complex samples were carried out (α = 5%). The prevalence of sleep bruxism among the preschool children was 26.9%. The multivariate analysis revealed that bruxism was associated with poor sleep quality (OR = 2.93; 95 CI: 1.52–5.65) and tooth wear (OR = 2.34; 95%CI: 1.39–3.96). In the present study, sleep bruxism among preschool children was associated with tooth wear and poor sleep quality of the child. In contrast, psychosocial aspects (sense of coherence) were not associated with sleep bruxism.

Resumo Este estudo avaliou as características epidemiológicas e de manejo dos casos de avulsão de dentes permanentes atendidos em um serviço de trauma dental de dezembro de 2005 a agosto de 2016. Foi realizado um estudo retrospectivo de 93 casos, envolvendo 139 dentes avulsionados. Os dados incluíram sexo, idade, etiologia do trauma, localização do acidente, número e posição dos dentes avulsionados e presença e tipo de lesões traumáticas associadas. O manejo dos dentes foi abordado de modo a analisar: o tempo decorrido até que os dentes fossem recuperados do local do acidente; Método de limpeza dos dentes e meios de armazenamento; Tempo decorrido até a busca por tratamento e reimplante dental. A maioria dos pacientes eram crianças de 6-10 (31,2%) e 11-15 anos (26,9%). Os pacientes do sexo masculino foram mais acometidos que do feminino. O acidente de bicicleta foi o principal fator etiológico (31,2%). Em 56 (60,2%) casos, ocorreram lesões traumáticas aos dentes vizinhos. Em 55 (59,1%) casos foram relatadas lesões de tecidos moles. Em 82 (88,2%) casos, os pacientes solicitaram tratamento no mesmo dia do acidente. Sessenta e quatro dentes (46,0%) foram imediatamente recuperados e 28 (20,1%) não foram encontrados. Quarenta e dois dentes (30,2%) foram mantidos secos. Apenas um dente (0,7%) foi imediatamente reimplantado no local do acidente, enquanto 51 dentes (36,7%) não foram reimplantados. Numerosos dentes avulsionados foram manejados de forma inadequada e o reimplante imediato não foi frequente. Devem ser criadas políticas públicas para a conscientização da população sobre as particularidades dos casos de avulsão dental.

Abstract This study assessed the epidemiological characteristics and management of the permanent teeth avulsion cases attended in a Brazilian dental trauma service from December 2005 to August 2016. A retrospective study was conducted of case records of 93 patients involving 139 avulsed teeth. Data included sex, age, trauma etiology, location of the accident, number and position of avulsed teeth, and presence and type of associated traumatic lesions. Management of the avulsed teeth was addressed as: time elapsed until teeth were retrieved from the accident’s location; teeth’s cleaning method and storage media; time elapsed until seeking treatment and replantation. The majority of the patients were children from 6-10 (31.2%) and 11-15 years old (26.9%). Male patients were more affected than female. Bicycle accident was the main etiological factor (31.2%). In 56 (60.2%) cases, traumatic lesions to neighboring teeth were present. In 55 (59.1%) cases, lesions to adjacent soft tissues were reported. In 82 (88.2%) cases, patients requested treatment at the same day of the accident. Sixty-four teeth (46.0%) were immediately retrieved and 28 (20.1%) were not found. Forty-two teeth (30.2%) were kept dry. Only one tooth (0.7%) was immediately replanted at the accident’s site, while 51 teeth (36.7%) were not replanted. Numerous avulsed teeth were inappropriately managed and immediate replantation was not frequent. Public policies must be created to raise awareness towards the particularities of avulsion cases.
