RESUMO
RESUMEN Esta investigación tuvo como objetivo informar la prevalencia de sífilis gestacional y congénita entre los años 2010 a 2019 en el estado de Mato Grosso do Sul, según datos de SINAN. Fue hecha una investigación documental y retrospectiva, con un enfoque cuantitativo. Se reportaron 8,791 casos de sífilis en mujeres embarazadas, el grupo de edad más afectado fue entre 20 y 29 años, con un total de 4,250 casos en este también con un mayor número de casos etnia parda. El diagnóstico de sífilis congénita se realizó con mayor frecuencia en una etapa reciente. Tanto las mujeres puerperales como sus parejas presentaron un tratamiento inadecuado. Con este estudio, fue posible observar un aumento en la sífilis gestacional y congénita a lo largo de los años estudiados, seguido de una caída, que puede denotar debilidades en la atención prenatal y la mujer embarazada, señalando que las mejoras son necesarias.
ABSTRACT This research aimed to report the prevalence of gestational and congenital syphilis between the years 2010 to 2019 in the state of Mato Grosso do Sul, based on data from SINAN. It was made a documentary and retrospective investigation, with a quantitative approach. 8,791 cases of syphilis were reported in pregnant women, the most affected age group was between 20 and 29 years old, with a total of 4,250 cases in this age group as also as with a greater number of cases for brown skin. The diagnosis of congenital syphilis was most often made at a recent stage. Both puerperal women and their partners presented inadequate treatment. In this study, it was possible to observe an increase in gestational and congenital syphilis over the years studied followed by a fall, which may denote weaknesses in prenatal care and the pregnant woman, pointing out that improvements are necessary.
RESUMO
Resume: La sífilis ocular es una forma infrecuente de neurosífilis, que se puede presentar en cualquier estadio de la enfermedad. La presentación clínica puede ser heterogénea, siendo la forma más frecuente la uveítis. El diagnóstico se confirma con serología, debiéndose realizar estudio del líquido cefalorraquídeo para descartar compromiso meníngeo. Su detección y tratamiento precoz permiten la prevención de complicaciones neurológicas como la ceguera irreversible. Presentamos el caso clínico de un paciente que se presenta con panuveítis y diagnóstico serológico de sífilis presentando excelente respuesta al tratamiento instaurado.
Abstract. Ocular syphilis is an uncommon type of neurosyphilis, which can occur at any stage of the disease. The clinical presentation can be heterogeneous, with uveitis being the most frequent form. The diagnosis is confirmed with serology and a study of the cerebrospinal fluid should be performed to rule out meningeal involvement. Its diagnosis and early treatment allow the prevention of neurological complications such as irreversible blindness. We present a clinical case of a patient who presents with panuveitis and serological diagnosis of syphilis presenting an excellent response to treatment.

RESUMO
El trasplante cardiaco pediátrico es una terapia efectiva para tratar la insuficiencia cardiaca avanzada. Objetivos: Analizar los resultados inmediatos y a mediano plazo de niños enlistados para trasplante cardiaco. Pacientes y Método: Se analizó el registro de pacientes enlistados para trasplante, entre octubre de 2001 y julio de 2016, analizando datos demográficos, diagnósticos, status de enlistamiento, tiempo de espera, datos de donantes, uso de asistencia ventricular, complicaciones y mortalidad. Resultados: La serie abarca 30 pacientes con edad promedio de 9,4 años (1 mes a 15 años). El diagnóstico principal fue miocardiopatía dilatada en 24 pacientes (80%). El status de ingreso fue I (urgencia) en 19 casos y II (no urgencia) en 11. Fallecieron 10 en la lista de espera (33,3%) en un promedio de 52 días (13 a 139 días). Catorce pacientes fueron trasplantados (46.7%), con un tiempo de espera de 199,6 días (4 a 586 días). Requirieron asistencia ventricular 9 pacientes (30%). Todos recibieron inmunosupresión tri asociada. Un paciente falleció a los 16 días por falla primaria del injerto (7,1%). El seguimiento promedio fue de 43 meses (0,5 a 159 meses). Dos pacientes fallecieron alejadamente (55 y 82 meses) por rechazo secundario al abandono de tratamiento inmunosupresor. La supervivencia a 1 y 5 años fue 93% y 74%, respectivamente. Conclusiones: Nuestro programa ha trasplantado al 50% de los pacientes enlistados con buena supervivencia a mediano plazo. Una proporción significativa de pacientes se enlistó con carácter de urgencia y un 34.5% de los pacientes fallecieron en la lista de espera.
Pediatric heart transplantation is an effective therapy to treat advanced heart failure in children. Objectives: To analyze the immediate and mid-term results of pediatric patients listed for heart transplantation. Patients and Methods: Registration of patients admitted to our transplant protocol between October 2001 and July 2016 were reviewed, analyzing demographic data, diagnosis, status at the time of listing, waiting time until transplantation, donor data, use of ventricular assist device, hemodynamic data, complications and global mortality. Results: Thirthy patients where included with a mean age of 9.4 years (1 month to 15 years). The most frequent diagnosis was dilated cardiomyopathy in 24 patients (80%). The status was I (urgency) in 19 cases and II in 11 cases. Ten patients died on the waiting list (33.3%) at an average of 52 days (13-139 days). Fourteen were transplanted (46.7%), with a waiting time of 199.6 days (4-586 days). Nine patients required mechanical support (30%). All patients received triple association of immunosuppression. One patient died 16 days post transplant due to primary graft failure (7.1%). The average follow-up was 43 months (0.5-159 months). Two patients died later on (82 and 55 months), both due to secondary rejection because of voluntary cessation of immunosuppressive therapy. Survival at 1 and 5 years was 93% and 74%, respectively. Conclusions: Our program has successfully transplanted 50% of patients enrolled, with good medium-term survival. A significant proportion of patients were listed as a medical emergency and 34.5% died on the waiting list.

LIS1 is a microtubule (Mt) plus-end binding protein that interacts with the dynein/dynactin complex. In humans, LIS1 is required for proper nuclear and organelle migration during cell growth. Although gene duplication is absent from Neurospora crassa, we found two paralogues of human LIS1. We named them LIS1-1 and LIS1-2 and studied their dynamics and function by fluorescent tagging. At the protein level, LIS1-1 and LIS1-2 were very similar. Although, the characteristic coiled-coil motif was not present in LIS1-2. LIS1-1-GFP and LIS1-2-GFP showed the same cellular distribution and dynamics, but LIS1-2-GFP was less abundant. Both LIS1 proteins were found in the subapical region as single fluorescent particles traveling toward the cell apex, they accumulated in the apical dome forming prominent short filament-like structures, some of which traversed the Spitzenkörper (Spk). The fluorescent structures moved exclusively in anterograde fashion along straight paths suggesting they traveled on Mts. There was no effect in the filament behavior of LIS1-1-GFP in the Δlis1-2 mutant but the dynamics of LIS1-2-GFP was affected in the Δlis1-1 mutant. Microtubular integrity and the dynein-dynactin complex were necessary for the formation of filament-like structures of LIS1-1-GFP in the subapical and apical regions; however, conventional kinesin (KIN-1) was not. Deletion mutants showed that the lack of lis1-1 decreased cell growth by â¼75%; however, the lack of lis1-2 had no effect on growth. A Δlis1-1;Δlis1-2 double mutant showed slower growth than either single mutant. Conidia production was reduced but branching rate increased in Δlis1-1 and the Δlis1-1;Δlis1-2 double mutants. The absence of LIS1-1 had a strong effect on Mt organization and dynamics and indirectly affected nuclear and mitochondrial distribution. The absence of LIS1-1 filaments in dynein mutants (ropy mutants) or in benomyl treated hyphae indicates the strong association between this protein and the regulation of the dynein-dynactin complex and Mt organization. LIS1-1 and LIS1-2 had a high amino acid homology, nevertheless, the absence of the coiled-coil motif in LIS1-2 suggests that its function or regulation may be distinct from that of LIS1-1.

A persistência do vírus da lagarta-da-soja AgMNPV, produzido de forma bruta (maceração de lagartas) e liofilizada (produto comercial), foi avaliada após a aplicação em plantas de soja seguida de diferentes regimes pluviométricos (0; 10; 20; 30mm) na intensidade de 30mm.hora-1. Essas precipitações foram simuladas com microaspersores, em casa-de-vegetação. Após a simulação, a soja foi oferecida às lagartas zero, três, seis e nove dias após a aplicação (DAP). As plantas, durante esse período, foram mantidas em casa-de-vegetação, protegidas da chuva. O experimento foi conduzido em delineamento inteiramente casualizado em condições controladas (UR 70±10%, 25±2°C, fotofase de 14h), em esquema fatorial 4 (intensidades de precipitações pluviométricas) x 2 (formulações de vírus, bruta e liofilizada) com quatro repetições, com 30 lagartas cada. Os resultados comprovam que precipitações até 30mm, em 60 minutos, não reduzem a mortalidade das lagartas, causada por AgMNPV em ambas as formas de produção, quando a oferta das folhas às lagartas ocorre no mesmo dia da aplicação. As formas de preparo do AgMNPV influenciaram na persistência do vírus aos seis DAP. Nesta avaliação, a taxa de mortalidade foi superior a 90%, quando o produto bruto foi aplicado e inferior a 50% para o produto liofilizado. Esses resultados indicam que a eficiência de AgMNPV não é afetada por chuvas de até 30mm em uma hora, para ambas as formas de preparo do AgMNPV. Entretanto, ao longo dos dias, o método de preparo bruto apresenta-se mais eficiente, devido à maior persistência sobre a área foliar da soja após a lavagem pela água.(AU)
The persistence of the velvet-bean nucleopolyhedrovirus (AgMNPV) produced raw (macerated caterpillars) and lyophilized (commercial product) was evaluated after spraying in soybean plants followed by different simulated rainfall rates (0; 10; 20; 30mm) at 30mm hour-1 rate. Rainfall was simulated in greenhouse through micro sprinkler irrigation. After simulated rainfall, soybean leaves were offered to caterpillar in laboratory conditions at zero, three, six and nine days after spraying (DAS). Soybean plants were kept in greenhouse protected from rainfall. Trial was carried out in complete randomized design, under controlled conditions (RH 70%±10%, 25±2°C, 14h photophase) in a factorial 4 (rainfall rates) x2 (formulations, raw and lyophilized) with four replicates of 30 caterpillars. Results indicate that rainfall rates up to 30mm, in 60 minutes, do not decrease caterpillar mortality caused by AgMNPV regarding to both tested baculovirus formulations, raw and lyophilized virus, when leaves were offered to caterpillars at zero DAS. However, virus production (raw or lyophilized) impacted its persistence. Six DAS, mortality rate was higher than 90% when the virus was applied raw and lower than 50% when it was applied lyophilized. These results suggest that both raw and lyophilized AgMNPV efficacy is not impaired by 30-mm rainfalls at 30mm hour-1 rate. However, raw virus was more efficient in a long term evaluation since it had longer persistence on soybean leaves after being water washed.(AU)
