Self-expanding mini-cannula for remote perfusion with pediatric scenarios.

The aim of this report is to address the benefits of the minimal invasive venous drainage in a pediatric cardio surgical scenario. Juvenile bovine experiments (67.4+/-11 kg) were performed. The right atrium was cannulated in a trans-jugular way by using the self-expandable (Smart Stat, 12/20F, 430 mm) venous cannula (Smartcannula LLC, Lausanne, Switzerland) vs. a 14F 250 mm (Polystan Lighthouse) standard pediatric venous cannula. Establishing the cardiopulmonary bypass (CPB), the blood flows were assessed for 20 mmHg, 30 mmHg and 40 mmHg of driving pressure. Venous drainage (flow in l/min) at 20 mmHg, 30 mmHg, and 40 mmHg drainage load was 0.26+/-0.1, 0.35+/-0.2 and 0.28+/-0.08 for the 14F standard vs. 1.31+/-0.22, 1.35+/-0.24 and 1.9+/-0.2 for the Smart Stat 12/20F cannula. The 43 cm self-expanding 12/20F Smartcannula outperforms the 14F standard cannula. The results described herein allow us to conclude that usage of the self-expanding Smartcannula also in the pediatric patients improves the flow and the drainage capacity, avoiding the insufficient and excessive drainage. We believe that similar results may be expected in the clinical settings.

Valoración de la calidad de vida tras implante de cabestrillo ajustable tipo remeex en incontinencia de orina femenina recidivada o insuficiencia esfinteriana intrínseca

Se evalúa la calidad de vida (CdV) tras implante de cabestrillo suburetral ajustable (Remeex). Se analizan 54 mujeres, clasificadas mediante Prueba de la tos, Qtip, y Urodinamia en: incontinencia de orina recidivada (IOEr: 25 casos) e incontinencia esfinteriana intrínseca (IEI:29 casos). La CdV se evalúa mediante el cuestionario específico Kings Health (KH). Tras un seguimiento medio de 49 meses, 46 pacientes (85%) estaban curadas de IOE. Las puntuaciones en CdV muestran una mejoría estadísticamente significativa en 8/9 dominios del KH. Podemos concluir que la cirugía de Remeex condiciona una mejoría estadísticamente significativa en la CdV percibida por las pacientes.

Uso de injerto dermo-graso para el tratamiento de la exposición del implante orbitario

La utilización de un implante orbitario es imprescindible para restaurar el volumen tras la evisceración o enucleación del globo ocular. Dicho volumen en la cavidad anoftálmica permitirá la utilización de una cascarilla que dará al paciente una mejor apariencia y simetría tras la pérdida del globo ocular. La exposición del implante orbitario es una de las complicaciones más frecuentes que nos encontramos tras evisceración o enucleación con la utilización de implante orbitario. Hay diferentes factores reconocidos que propiciarán dicha exposición, entre los que se encuentran la colonización del implante, escasez de mucosa conjuntival, tamaño y composición del implante, etc... Hay diferentes opciones de tratamiento de la exposición del implante orbitario que incluyen la utilización de tejidos por medio de injerto o flap o bien la extracción del propio implante con la consecuente afectación en la apariencia del paciente. El uso de injerto dermo-graso ha sido descrito con anterioridad, pero no hemos encontrado un estudio de una serie de casos que demuestre su utilidad. Nuestro objetivo es determinar la efectividad del injerto dermo-graso en el tratamiento de la exposición del implante orbitario en la cavidad anoftálmica. Para ello estudiamos la evolución de 15 pacientes que presentaron exposición de implante orbitario, tras enucleación o evisceración, y a los que se les ha tratado dicha exposición con un injerto dermo-graso. Se evaluan clínicamente los resultados de dicha técnica en estos pacientes, en algún caso hasta 22 meses tras la intervención.

Daño neurológico detectado por RM difusión y variaciones en el estado neurocognitivo tras implante de TAVI vs. RVA en pacientes con similar perfil de riesgo:) Datos preliminares

El presente trabajo muestra los datos preliminares de una estudio de cohortes prospectivo unicéntrico que pretende comparar el daño neurológico asociado a dos intervenciones cardiacas para el tratamiento de la estenosis aórtica severa. Concretamente se analiza la aparición de lesiones isquémica agudas cerebrales detectadas por RM tras los dos procedimientos y su posible asociación con alteraciones del estado neurocognitivo en la evolución. La presentación actual solo muestra los datos preliminares de los resultados de la RM cerebral. En el apartado métodos se describe también como se realizó la valoración del estado neurocognitivo, no obstante, los resultados de estas valoraciones y su posible correlación con las lesiones en la RM cerebral aún no estan analizados y por lo tanto no se presentan.

Mini-STRs em genética forense

A análise do ADN baseada nos STRs (Short Tandem Repeats) tem provado ser uma ferramenta extremamente útil em estudos forenses. A aplicação dos multiplex de STRs resulta em perfis genéticos completos, para a maior parte das amostras, desde que contenham uma quantidade apreciável de ADN. Contudo, em amostras com ADN degradado, a análise tornase mais complicada, uma vez que os STRs com maior peso molecular (acima dos 250 pb), podem não ser amplificados nestas condições. Como a metodologia de Mini-STRs não estava, ainda, implementada nos Laboratórios Forenses portugueses, o objectivo principal deste estudo consistiu na aplicação de um multiplex, designado por Mini-SGM, que contém os marcadores TH01, FGA, D18S51, D16S359, D2S1338 e a Amelogenina, para implementação na prática forense, tendo os resultados sido comparados com a metodologia de rotina. O trabalho experimental teve início com um estudo populacional, que compreendeu uma amostra de 110 indivíduos de origem portuguesa, não relacionados e uma amostra de 52 indivíduos, não relacionados, oriundos de Cabo Verde, encontrando-se, ambas as populações, em Equilíbrio de Hardy-Weinberg, excepto para o locus D18S51, na população portuguesa e o locus D2S1338 na população de origem africana. Em relação aos parâmetros estatísticos forenses, este estudo demonstrou que o poder de discriminação varia entre 0,903 e 0,959, para a população portuguesa, e entre 0,908 e 0,958, para a população de Cabo Verde. Após o estudo populacional, foram analisados 39 casos forenses, devidamente anonimizados, da casuística do Serviço de Genética e Biologia Forense da Delegação de Lisboa do INML, com diferentes tipos de vestígios biológicos, como sangue, ossos, pulmão, coração, tecidos embrionários, tecidos inclusos em parafina, fígado, rim e dentes, de modo a ilustrar a utilidade desta nova metodologia nos casos forenses. No estudo de amostras degradadas, o uso da metodologia de rotina pode,

Validation of the Mini Nutritional Assessment short-form (MNA-SF): a practical tool for identification of nutritional status.

OBJECTIVE: To validate a revision of the Mini Nutritional Assessment short-form (MNA(R)-SF) against the full MNA, a standard tool for nutritional evaluation. METHODS: A literature search identified studies that used the MNA for nutritional screening in geriatric patients. The contacted authors submitted original datasets that were merged into a single database. Various combinations of the questions on the current MNA-SF were tested using this database through combination analysis and ROC based derivation of classification thresholds. RESULTS: Twenty-seven datasets (n=6257 participants) were initially processed from which twelve were used in the current analysis on a sample of 2032 study participants (mean age 82.3y) with complete information on all MNA items. The original MNA-SF was a combination of six questions from the full MNA. A revised MNA-SF included calf circumference (CC) substituted for BMI performed equally well. A revised three-category scoring classification for this revised MNA-SF, using BMI and/or CC, had good sensitivity compared to the full MNA. CONCLUSION: The newly revised MNA-SF is a valid nutritional screening tool applicable to geriatric health care professionals with the option of using CC when BMI cannot be calculated. This revised MNA-SF increases the applicability of this rapid screening tool in clinical practice through the inclusion of a "malnourished" category.

Traitement mini-invasif sous contrôle scanner et fluoroscopique de la lyse isthmique vertébrale : une nouvelle technique.

Objectifs: Evaluer la faisabilité, les résultats préliminaires à court et long terme du vissage percutané de vissage trans -isthmique sous anesthésie locale et contrôle scannerdes lyses isthmiques de bas grades.Matériels et méthodes: Etude prospective monocentrique réalisée sur 10 patients ayant une lyse isthmique grade 1 et 2 résistant au traitement médical conventionnel. Une évaluationclinique était réalisée à un mois, 3 mois, 6 mois et un an post-opératoire par un évaluateur indépendant. L'indication est posée en concertation avec le service dechirurgie orthopédique.Résultats: Les lyses isthmiques étaient situées en L5-S1 avec 6 grades 1 et 4 grades 2. L'échelle analogique de la douleur (VAS) variait de 6 a 9 avec une moyenne de 7,8.L'indication opératoire chirurgicale était posée pour tous les patients par arthrodèse postérieure lombo -sacree. Pour chaque patient 2 vis étaient positionnées soitun total de 20 vis. Un suivi clinique était réalisé de 28 a 36 mois. L'EVA et ODI diminuaient de 7,8 +/- 1,7 à 1,9 +/- 1,2 et de 62,3 +/- 17,2 à 15,1 +/- 6,0respectivement. L'ensemble des résultats était stable dans le temps en particulier à long terme.Conclusion: La fixation précise de la lyse isthmique améliore la symptomatologie et probablement évite un glissement vertébral plus important , un suivi à plus long terme surune serie de patients plus importante devrait confirmer cette hypothèse.

Prothèse totale de la hanche par voie antérieure "mini-invasive" [Total hip arthroplasty through anterior "minimal invasive" approach].

Total hip replacement has seen a tremendous development and has become one of the most successful surgical interventions in orthopaedics. While during the first decades of development of total hip arthroplasty the fixation of the implant into the bone was the main concern, the focus has shifted towards surgical technique and soft tissue handling. In order to avoid permanent soft tissue damage, muscular dysfunction and concerns in regards to cosmetics, minimal invasive and anatomic approaches have been developed. We here provide a short overview on various methods of total hip replacements and we describe our technique through a minimal invasive direct anterior approach. While muscle and nerve damage is minimal, this technique allows for a rapid rehabilitation and is associated with an excellent functional outcome and a minimal risk for dislocation.

Evaluation of Mini Slump Cone Test, MLR-97-01, 2000

Early stiffening of cement has been noted as contributing to workability problems with concrete placed in the field. Early stiffening, normally attributed to cements whose gypsum is reduced to hemi⋅hydrate or anhydrate because of high finish mill temperatures, is referred to as false setting. Stiffening attributed to uncontrolled reaction of C3A is referred to as flash set. False setting may be overcame by extended mix period, while flash setting is usually more serious and workability is usually diminished with extended mixing. ASTM C 359 has been used to detect early stiffening with mixed results. The mini slump cone test was developed by Construction Technology Laboratories (CTL), Inc., as an alternative method of determining early stiffening. This research examined the mini slump cone test procedure to determine the repeatability of the results obtained from two different testing procedures, effect of w/c ratio, lifting rate of the cone, and accuracy of the test using a standard sample.

Enterocystoplasty using modified pedicled, detubularized, de-epithelialized sigmoid patches in the mini-pig model.

Enterocystoplasty and gastrocystoplasty have been developed to restore adequate bladder capacity but they still result in the undesired harmful contact of urine with the intestinal mucosa. In an attempt to prevent this nonphysiological interface we performed several modified enterocystoplasties in the mini-pig model using a pedicled, detubularized, de-epithelialized sigmoid patch. Five techniques of patch coverage were used to evaluate urothelial growth or survival on the sigmoid patch. All but 1 patch had intestinal mucosa remnants with mucocele formation. When no coverage was applied or a biodegradable polyglactin mesh was temporarily covering the pedicled, detubularized, de-epithelialized sigmoid patch, severe shrinkage occurred. Partial cover with autologous urothelium islets seemed to decrease shrinkage. Adequate urothelium survival and satisfactory elastic properties of the patch were observed when total cover of the sigmoid patch was achieved with a sheet of homologous urothelium recovering autologous urothelial islets or when the patch was applied to protruding urothelium obtained following sagittal posterior detrusor myotomy.

Pollination requirements of seeded and seedless mini watermelon varieties cultivated under protected environment

The objective of this work was to evaluate the floral biology and pollination requirements of seeded and seedless mini watermelon varieties, and to determine the best varieties to cultivate under protected environment. Three seedless (HA-5106, HA-5158, and HA-5161) and two seeded (Minipol and Polimore) genotypes were tested. Flowers were monitored from the pre-anthesis stage to senescence, and fruit quality was also evaluated. The evaluated treatments were hand-geitonogamous pollination (MG), cross-pollination with pollen from the Polimore variety (MCP), cross-pollination with pollen from the Minipol variety (MCM), and restricted pollination. All varieties had monoecious plants with diclinous flowers, and the stigmas remained receptive throughout anthesis. Fruit set rates of 84.62% (MG), 61.54% (MCP), 48% (MCM), and 0% (restricted) were obtained for seeded varieties, but of 0% (MG), 76.36% (MCP), 82.69% (MCM), and 0% (restricted) for seedless varieties. Fruits did not differ in quality among treatments within each genotype. Therefore, all the studied varieties require a pollination agent and diploid pollen for fruit set to occur, regardless of the donor variety; and Minipol or Polimore with HA-5106 or HA-5158 are the varieties recommended for cultivation in protected environment.
