RESUMO

Con el advenimiento de nuevas técnicas quirúrgicas y medicaciones inmunosupresoras la sobrevida de los niños trasplantados mejoró, llegando a la adultez. La continuidad de su tratamiento requiere un proceso planificado que permita su tránsito a un sistema de salud orientado al adulto. El objeto de este trabajo es mostrar la transición a centros de adultos en una cohorte de pacientes trasplantados renales en el Hospital Garrahan, describir sus características clínicas y demográficas, su evolución, y oportunidades de mejora implementadas. Debido a cambios médicos y su abordaje desde la interdisciplina, se dividió a la población en tres periodos: era 1 (1988-1999), era 2 (2000-2009), y era 3 (2010- 2023). En la era 1, 179 adolescentes continuaron su atención médica en un centro de adultos, 212 en la era 2 y 201 en la era 3. En la era 1 el seguimiento estaba coordinado por el nefrólogo de cabecera y eran consultados los servicios de Urología, Servicio Social y Salud Mental. En la era 2, se fortaleció el trabajo en interdisciplina y aún más a partir del 2011. Surgieron centros de trasplante de adultos que recibían adolescentes y médicos dedicados a ellos en forma preferencial. En la actualidad la transición comienza a los 12 años y progresa hasta los 18. El modelo implementado es la transición directa, entre el nefrólogo pediatra y el de adultos, con varias consultas secuenciales en ambos centros. Si bien la sobrevida del paciente e injerto mejoraron, el rechazo, asociado a no adherencia, es una asignatura por mejorar (AU)

With the advent of new surgical techniques and immunosuppressive medications, the survival of transplanted children has improved, allowing them to reach adulthood. The continuity of their treatment requires a planned process that facilitates their transition to an adult-oriented healthcare system. The aim of this study was to examine the transition to adult centers in a cohort of renal transplant patients at Garrahan Hospital, describing their clinical and demographic characteristics, their evolution, and the improvement opportunities implemented. Based on medical changes and the interdisciplinary approach, the population was divided into three periods: era 1 (1988- 1999), era 2 (2000-2009), and era 3 (2010-2023). In era 1, 179 adolescents continued their medical care in an adult center, 212 in era 2, and 201 in era 3. In era 1, follow-up was coordinated by the attending nephrologist with consultations from Urology, Social Services, and Mental Health Services. In era 2, interdisciplinary work was strengthened, and even more so since 2011. Adult transplant centers were created to receive adolescents with physicians dedicated to their care on a preferential basis. Currently, the transition begins at 12 years of age and progresses up to 18. The implemented model involves direct transition between the pediatric nephrologist and the adult nephrologist, with several sequential consultations in both centers. Although patient and graft survival have improved, rejection associated with non-adherence remains an area for improvement

RESUMO

Abstract Fitness in parasitoids is generally influenced by host quality. We evaluated the development parameters of Doryctobracon areolatus (Hymenoptera: Braconidae) parasitoid on Anastrepha fraterculus (Diptera: Tephritidae) larvae, reared in artificial diets with different protein sources. Larvae of A. fraterculus were reared in the diets based on 1) raw wheat germ (control); 2) whole rice flour; 3) corn flour; and, 4) whole wheat flour + soybean meal. The larvae were used for the development of D. areolatus, to evaluate the number of offspring/female, emergence rate, sex ratio, egg-adult period, adult weight posterior tibia length and longevity. Larvae of A. fraterculus reared in the diets based on wheat germ and corn flour obtained a greater number of offspring, with shorter duration of egg-adult period for males and females. In diets with rice flour and corn flour, A. fraterculus larvae generated adults of D. areolatus with greater weight, longer tibia length and higher sex ratio, whereas larvae reared in wheat flour + soybean meal diet had a lower sex ratio. The diets based on rice flour and corn are the most appropriate for multiplication of the parasitoid.

Nós avaliamos parâmetros de desenvolvimento do parasitoide Doryctobracon areolatus (Hymenoptera: Braconidae) em larvas de Anastrepha fraterculus (Diptera: Tephritidae) criadas em dieta artificial com diferentes fontes proteicas. Larvas de A. fraterculus foram criadas em dietas a base de: 1) germe de trigo cru (testemunha); 2) farinha de arroz integral; 3) farinha de milho; e, 4) farinha de trigo integral + farelo de soja. As larvas foram usadas para o desenvolvimento de D. areolatus para avaliar o número de descendentes/fêmea, taxa de emergência, razão sexual, duração do período ovo-adulto, peso de adultos, comprimento da tíbia posterior e longevidade. Larvas de A. fraterculus criadas nas dietas a base de germe de trigo e farinha de milho, permitiram obter um maior número de descendentes do parasitoide, com menor duração do período de desenvolvimento ovo-adulto, para ambos os sexos. Nas dietas com farinha de arroz e farinha de milho, larvas de A. fraterculus geraram adultos de D. areolatus com maior peso e tamanho de tíbia de machos e fêmeas e uma maior quantidade de fêmeas. A dieta contendo farinha de trigo + farelo de soja afetou a geração de descendentes, causando uma menor razão sexual. As dietas a base de farinha de arroz e milho são as mais adequadas para a multiplicação do parasitoide.

RESUMO

Drosophila suzukii (Matsumura) is an invasive species originating in Southeast Asia and considered a severe pest in berry crops in several countries of the Northern Hemisphere and Europe. In South America, the species was first detected in 2013. The objective of the study was to monitor the seasonal activity of D. suzukii in commercial crops of blackberry, strawberry guava, surinam cherry, blueberry, and strawberry during two consecutive harvests and in three properties in the Southern region of Brazil during the 2015/2016 and 2016/2017 harvests, with the aid of traps baited with apple cider vinegar. The highest population peaks were observed during late spring to mid-fall in all areas and plant species studied. It was verified that temperature is the factor that most influenced the seasonal activity of D. suzukii in the field, promoting low catches of the species during winter. However, even during periods of low temperatures (winter period), the presence of D. suzukii in the crops was verified, demonstrating the species' ability to stay in place from year to year, surviving in alternative hosts such as Eriobotrya japonica, a common species in the region. The information on the time of the highest occurrence of the pest in different hosts presented in this study provides the basis for decision-making in relation to the management of D. suzukii, to avoid further economic damage.

RESUMO

Abstract Fruit flies (Diptera: Tephritidae) are considered the main fruit pests worldwide. In Brazil, two species are predominant: the South American fruit fly, Anastrepha fraterculus and the Mediterranean fruit fly, Ceratitis capitata. In this study, we evaluated the effect of artificial diets with variable pH in their larval development and adult performance. The experiments were carried out in the laboratory at 25 ± 2 °C, 70 ± 10% RH and 12:12h (L:D) photoperiod. Semisolid diets with pH values of 6.0, 5.0, 4.0, 3.0, 2.0, 1.5, and 1.0, adjusted by adding hydrochloric acid were tested. Results indicated that the diet with pH 6.0 did not support larval development of both species of fruit fly. Diets with greater acidic pH values did not allow egg, larvae or pupae development and adult reproduction of A. fraterculus. For C. capitata , the pH of artificial diet exerts greater influence compared to A. fraterculus on the duration and viability of the larval stage, number of pupae, sex ratio and longevity of males.

Resumo As moscas-das-frutas (Diptera: Tephritidae) são consideradas as principais pragas da fruticultura mundial. No Brasil, duas espécies são predomindantes: a mosca-das-frutas Sul-americana, Anastrepha fraterculus e a mosca-do-Mediterrâneo, Ceratitis capitata. Neste estudo avaliamos o efeito de dietas artificiais com pH variável no seu desenvolvimento larval e performance de adultos. Os experimentos foram realizados em laboratório a 25 ± 2 °C, 70 ± 10% UR e fotoperíodo de 12:12 horas. Foram testadas dietas semi-sólidas com valores de pH de 6,0; 5,0; 4,0; 3,0; 2,0; 1,5 e 1,0, ajustados pela adição de ácido clorídrico. Os resultados indicaram que a dieta com pH 6,0 não suportou o desenvolvimento larval de ambas as espécies de mosca-das-frutas. As dietas com pH ácido não permitiram o desenvolvimento de ovos, larvas ou pupas e a reprodução de adultos de A. fraterculus. Para C. capitata o pH da dieta artificial exerceu maior influência do que para A. fraterculus nos parâmetros de duração e viabilidade do estágio larval, número de pupas, razão sexual e longevidade de machos.

RESUMO

Abstract The development and reproductive potential of Spodoptera eridania (Stoll, 1782) (Lepidoptera, Noctuidae) was compared on natural and artificial diets. Its biology was determined under laboratory conditions, providing an artificial diet, leaves of white clover and the peach cultivar 'Chimarrita' and fruits and leaves of the apple cultivar 'Gala'. Larvae of S. eridania could not complete their biological cycle when fed on apple fruits or peach leaves. The artificial diet provided the shortest development time, with a cycle of 28.5±0.14 days from egg to adult and 37.3% total viability. Apple leaves led to a longer development time from egg to adult (62.8±1.22 days) and lower total viability (23%) and white clover provided the highest total viability (54.3%). The results showed that S. eridania can use white clover and apple leaves to develop normally in apple orchards. The reduction of food sources such as white clover used by the larvae results in infestation and damage to fruits from "test bites".

Resumo O desenvolvimento e o potencial reprodutivo de Spodoptera eridania (Stoll, 1782) (Lepidoptera, Noctuidae) foi comparado em dietas naturais e artificial. A biologia de S. eridania foi determinada em condições de laboratório, comparando-se uma dieta artificial com folhas de trevo branco e de pêssego da cultivar 'Chimarrita' e frutos e folhas de maçã da cultivar 'Gala'. As larvas de S. eridania não puderam completar seu ciclo biológico quando alimentadas com frutas de maçã ou folhas de pêssego. A dieta artificial proporcionou o menor tempo de desenvolvimento, com um ciclo completo de 28,5 ± 0,14 dias de ovo a adulto e 37,3% de viabilidade total. As folhas de maçã levaram maior tempo de desenvolvimento de ovo a adulto (62,8 ± 1,22 dias) e menor viabilidade total (23%). O trevo branco apresentou a maior viabilidade total (54,3%). Os resultados mostraram que S. eridania pode usar trevo branco e folhas de maçã para se desenvolver normalmente em pomares de maçã. A redução de fontes alimentares, como o trevo branco usado pelas larvas, resulta em infestação e danos aos frutos através das "mordidas de prova".
