Comparación de la eficacia de distintos productos químicos aplicados mediante tratamiento aéreo en el control del muérdago (Viscum album) sobre Pinus halepensis

El objetivo de este trabajo fue comparar la eficacia de diversos productos químicos en el control del muérdago (Viscum album var austriacum) sobre Pinus halepensis. La experiencia consistió en la aplicación mediante tratamiento aéreo de diversas concentraciones de etefon, ácido giberélico y glifosato. Las combinaciones de ácido giberélico y glifosato obtuvieron las mayores eficacias, especialmente la que aplicó 7,8 g/ha de ácido giberélico y 540 g/ha de glifosato.

Daños de Palaeococcus fuscipennis Burm (Homoptera: Margarodidae) en pinos y cipreses de los parques de Lleida

Durante el inicio de la primavera del 2001 (primera quincena de abril) se detectaron ataques muy fuertes de Palaeococcus fuscipennis Burm. en Pinus halepensis y en Pinus pinea en los parques municipales de Lleida. Algunos ejemplares de Cupressus sempervirens fueron también fuertemente atacados. Se ha estudiado la evolución del margaródido en árboles tratados contra la cochinilla y sin tratar, se ha comparado el ataque en P. pinea y P. halepensis y se ha evaluado la presencia de enemigos naturales.

Randomized clinical trial on epidural versus patient-controlled analgesia for laparoscopic colorectal surgery within an enhanced recovery pathway.

OBJECTIVE: To compare epidural analgesia (EDA) to patient-controlled opioid-based analgesia (PCA) in patients undergoing laparoscopic colorectal surgery. BACKGROUND: EDA is mainstay of multimodal pain management within enhanced recovery pathways [enhanced recovery after surgery (ERAS)]. For laparoscopic colorectal resections, the benefit of epidurals remains debated. Some consider EDA as useful, whereas others perceive epidurals as unnecessary or even deleterious. METHODS: A total of 128 patients undergoing elective laparoscopic colorectal resections were enrolled in a randomized clinical trial comparing EDA versus PCA. Primary end point was medical recovery. Overall complications, hospital stay, perioperative vasopressor requirements, and postoperative pain scores were secondary outcome measures. Analysis was performed according to the intention-to-treat principle. RESULTS: Final analysis included 65 EDA patients and 57 PCA patients. Both groups were similar regarding baseline characteristics. Medical recovery required a median of 5 days (interquartile range [IQR], 3-7.5 days) in EDA patients and 4 days (IQR, 3-6 days) in the PCA group (P = 0.082). PCA patients had significantly less overall complications [19 (33%) vs 35 (54%); P = 0.029] but a similar hospital stay [5 days (IQR, 4-8 days) vs 7 days (IQR, 4.5-12 days); P = 0.434]. Significantly more EDA patients needed vasopressor treatment perioperatively (90% vs 74%, P = 0.018), the day of surgery (27% vs 4%, P < 0.001), and on postoperative day 1 (29% vs 4%, P < 0.001), whereas no difference in postoperative pain scores was noted. CONCLUSIONS: Epidurals seem to slow down recovery after laparoscopic colorectal resections without adding obvious benefits. EDA can therefore not be recommended as part of ERAS pathways in laparoscopic colorectal surgery.

Rétablissement postopératoire optimisé, applique aux patients après cystectomie [Enhanced recovery after surgery applied to cystectomy patients].

Enhanced Recovery After Surgery (ERAS) is a multimodal concept combining pre, intra and postoperative evidence-based care elements to reduce surgical stress. ERAS pathways have been shown to significantly reduce morbidity, length of hospital stay and total costs when applied to colorectal surgery. It is therefore considered standard of care in this specialty. There can be no doubt that ERAS principles can be applied also in other major surgeries. However, uncritical application of the guidelines issued from colonic procedures seems inappropriate as the surgical procedures in pelvic cancer surgery differ considerably. This article reports on the first steps of an ERAS project and his introduction in urology.

Réhabilitation améliorée après chirurgie--L'ere de la prise en charge optimale du patient chirurgical [Enhanced Recovery After Surgery--optimal management of the surgical patient].

Enhanced Recovery After Surgery (ERAS) is a multimodal, standardized and evidence-based perioperative care pathway. With ERAS, postoperative complications are significantly lowered, and, as a secondary effect, length of hospital stay and health cost are reduced. The patient recovers better and faster allowing to reduce in addition the workload of healthcare providers. Despite the hospital discharge occurs sooner, there is no increased charge of the outpatient care. ERAS can be safely applied to any patient by a tailored approach. The general practitioner plays an essential role in ERAS by assuring the continuity of the information and the follow-up of the patient.

Aplicação foliar de nitrogênio em videira: avaliação do teor na folha e das reservas nitrogenadas e de carboidratos nas gemas dos ramos do ano

No Rio Grande do Sul (RS), as aplicações foliares de nitrogênio, quando necessárias, têm sido usadas para complementar a adubação via solo. Entretanto, carece-se de informações dos efeitos da freqüência e da quantidade de N aplicado sobre a sua dinâmica na folha e de reservas nitrogenadas e de carboidratos nas partes perenes da videira, que compõem o objetivo deste trabalho. O trabalho foi conduzido em um vinhedo da cultivar Chenin Blanc, safra 2004/05, na Embrapa Uva e Vinho, em Bento Gonçalves (RS), sobre um Neossolo Litólico. Os tratamentos consistiram de uma, duas e três aplicações foliares de 0 (água); 1,11; 2,23; 3,31 e 4,41g de N planta-1. Após cada aplicação de nitrogênio, foram coletadas folhas inteiras (limbo+pecíolo) no terço médio dos ramos do ano, no interior e exterior dos diferentes lados da planta, secas, moídas e preparadas para a análise de N total. Na última época de coleta de folhas, foram coletados três ramos do ano em cada planta, retiradas seis gemas em cada ramo, as quais foram submetidas à análise de amido, carboidratos solúveis totais, carboidratos redutores, aminoácidos totais e proteínas totais. As aplicações foliares de N aumentaram o teor do nutriente na folha inteira, de forma destacada, nas épocas de coletas próximas às aplicações; entretanto, essas aplicações diminuíram os teores de amido e carboidratos solúveis totais nas gemas dos ramos do ano e não afetaram os teores de carboidratos redutores e os totais de aminoácidos e proteínas.

Left temporal lobe epilepsy revealing left posterior cortical atrophy due to Alzheimer's disease.

Seizures can be an early symptom of Alzheimer's disease (AD) and can precede cognitive decline. Early epilepsy in AD can mimic transient epileptic amnesic syndrome (TEAS) or epileptic amnesic syndrome. We report the case of a patient who started a cerebrospinal fluid (CSF)-proven AD with partial seizures and TEAS that secondarily became a cortical posterior atrophy syndrome. CSF biomarkers showed a high amyloid production, amyloidopathy, and high level of total tau and p-Tau. This observation adds data to the complex AD-early epilepsy interactions and illustrates that atypical AD can cause a TEAS. Possible red flags for an underlying neurodegenerative process in TEAS are discussed.

Disseny d’una plataforma per a la pràctica del boccia

El boccia és un esport internacional molt similar a la petanca. Hi participen personesamb cadira de rodes, amb greus afectacions per paràlisis cerebral i altres discapacitatsfísiques severes. A partir de la categoria BC3 (discapacitats en ambdós extremitats) labola es tira a través d’una rampa o canaleta ajustable en altura, inclinació i direcció. Ésun joc de precisió i estratègia.El joc consisteix en tirar una bola diana de color blanc, i acostar-s’hi el més possible. Eljugador o equip que s’hi acosta més suma punts, quan han passat un cert nombre derondes l’equip amb més punts és el guanyador.Degut a que els participants no poden moure ni els braços ni les cames, han de donarindicacions a un auxiliar perquè els hi reguli la rampa.Empreses i participants del col•lectiu del boccia ens ha demanat alguna solució perpoder prescindir de l’auxiliar a la hora d’ajustar la rampa. L’auxiliar haurà de seguircol•locant la bola de boccia i deixar-la anar des de la part superior de la rampa. Peròaixí el participant podrà regular ell mateix la posició de la rampa, millorant així la sevaexperiència en el joc.Es dissenyarà un mecanisme perquè un discapacitat pugui jugar a la boccia. Ha depermetre un control total del posicionament de la rampa, per part del discapacitat:Moviment de translació vertical, rotació en l’eix z per poder canviar la inclinació i unmoviment de rotació en l’eix y per poder ajustar la direcció. La intenció és automatitzarla rampa amb un mecanisme d’actuadors elèctrics, perquè el jugador, mitjançant un panell de control equipat amb joysticks pugui ajustar la rampa segons les sevesnecessitats
