Efecto de la profundidad del bloqueo neuromuscular sobre el espacio abdominal y las condiciones quirúrgicas durante la cirugía laparoscópica abdomina…
2017
Introducción: La anestesia aparece como un factor clave en el desarrollo del proceso asistencial de la cirugía laparoscópica, por su capacidad de actuar tanto sobre los factores barrera que condicionan el período postoperatorio y el alta hospitalaria precoz, como por la posibilidad de influir en la optimización de las condiciones quirúrgicas. Sin embargo, mientras que existen recomendaciones con una evidencia científica de grado A en cuanto a intervenciones sobre el control de las náuseas/vómitos postoperatorios(NVPO), estrategias para el control del dolor postquirúrgico o para la mejora en la calidad de la recuperación postoperatoria, la evidencia científica presente hasta el momento en re…
Use of CD64 for the diagnosis of sepsis: a case-control study.
2010
CD64 is the high-affinity receptor of IgG. It is upregulated by inflammatory cytokines on neutrophils. The upregulation of CD64 is linked with PMN activation in SIRS or sepsis. Our aim is to verify these correlations.
Efectos de la aplicación de un protocolo de entrenamiento de fuerza previo, a la cirugía de artroplastía total de rodilla en pacientes mayores de 60 …
2015
La indicación mas frecuente para implantar una prótesis total de rodilla es eliminar el dolor y restaurar la movilidad causada por una gran destrucción articular en el cartílago, como ocurre con la osteoartritis. La cirugía de reemplazo de articulaciones es una intervención eficaz utilizada cada vez más para osteoartritis de cadera y de rodilla. Los pacientes diagnosticados de osteoartritis primaria avanzada que son susceptibles de recibir una prótesis total de rodilla, debido al dolor y la rigidez articular evitan utilizar la articulación durante las actividades de la vida diaria, como caminar y subir escaleras, de forma que adoptan una actitud sedentaria, afectando a la musculatura implic…
Immune checkpoint inhibitors-associated pericardial disease: a systematic review of case reports
2021
Treatment with immune checkpoint inhibitors (ICIs) can be complicated by cardiovascular toxicity, including pericardial disease. To date, no prospective studies specifically investigated the optimal treatment of ICI-associated pericardial disease, and the available evidence is based on case reports and series only. We performed a systematic review of case reports and series including 20 publications for a total of 28 cases of ICI-associated pericardial disease. In this review, pericardial disease was reversible in the majority of cases (75%), although 2 deaths were reported. The majority of cases were life-threatening (G4, 53.6%) or severe (G3, 21.4%), requiring pericardiocentesis. Higher r…
Candida bloodstream infections in intensive care units: Analysis of the extended prevalence of infection in intensive care unit study
2011
Objectives: To provide a global, up-to-date picture of the prevalence, treatment, and outcomes of Candida bloodstream infections in intensive care unit patients and compare Candida with bacterial bloodstream infection. Design: A retrospective analysis of the Extended Prevalence of Infection in the ICU Study (EPIC II). Demographic, physiological, infection-related and therapeutic data were collected. Patients were grouped as having Candida, Gram-positive, Gram-negative, and combined Candida/bacterial bloodstream infection. Outcome data were assessed at intensive care unit and hospital discharge. Setting: EPIC II included 1265 intensive care units in 76 countries. Patients: Patients in partic…
Quantitative global mapping of terrestrial vegetation photosynthesis
2017
Although traditional remote sensing systems based on spectral reflectance can already provide estimates of the 'potential' photosynthetic activity of terrestrial vegetation through the quantification of total canopy chlorophyll content or absorbed photosynthetic radiation, the determination of the 'actual' photosynthetic activity of terrestrial vegetation requires information about how the absorbed light is used by plants, such as vegetation fluorescence, using very high spectral resolution spectroscopy in the range 650-800 nm. The Fluorescence Explorer (FLEX) mission, selected in November 2015 as the 8th Earth Explorer by the European Space Agency (ESA), carries the FLORIS spectrometer, wi…
Synthesis of Multisubstituted 1,4-Dihydrobenzoxazin-2-ones through a One-Pot Nucleophilic N-Alkylation/C-Alkylation of Cyclic α-Imino Esters
2017
A nucleophilic N-alkylation of 2-oxobenzoxazine-2-carboxylates with organozinc reagents with good selectivities and in moderate to good yields is described. Moreover, the synthesis of multisubstituted 1,4-dihydrobenzoxazine-2-ones bearing a tetrasubstituted carbon atom via a one-pot N-alkylation/C-alkylation reactions is reported.
Dificultad en el tratamiento del hipertiroidismo por amiodarona: Presentación de un caso
2007
La amiodarona puede alterar la función tiroidea en un 15-20% de los pacientes que la toman, dando lugar a hipotiroidismo o hipertiroidismo. La sobrecarga de yodo y la toxicidad directa sobre el tiroides inducida por amiodarona pueden provocar hipertiroidismo. Describimos un caso de tirotoxicosis grave por amiodarona que se diagnosticó buscando la causa que descompensó la cardiopatía de base del paciente, condicionando ésta el pronóstico y el manejo terapéutico. El tratamiento precisó un estrecho seguimiento y se basó en dosis elevadas de propiltiouracilo y dexametasona que no controlaron las consecuencias del hipertiroidismo a nivel cardiaco necesitando la tiroidectomia total. Creemos, con …
CARDIOPROTEZIONE ED ANESTESIA EPIDURA- LE TORACICA: UN CASO DI ISCHEMIA MIOCAR- DICA POSTOPERATORIA
2013
Obiettivo. Analisi dell’effetto cardioprotettivo perioperatorio dell’anestesia peridurale toracica (TEA) in un paziente car- diopatico sottoposto a chirurgia non cardiaca. Materiali e metodi. Paziente di 59 anni affetto da patologia neoplastica, BPCO severa, insufficienza renale cronica e car- diopatia ipertensiva (ASA IV), viene sottoposto ad intervento chirurgico di cistectomia radicale e resezione duodeno-digiu- nale. In fase preoperatoria si posiziona un catetere epidurale (T10) e si somministra un bolo di Levobupivacaina (75 mg) e Fentanest (0,05 mg). Si procede a monitoraggio intraoperato- rio con CardioQ che evidenzia uno stato ipotensivo iniziale con bassa portata e basse resistenze…
Understanding a Cartesian graph using the motion sensor
2008
This paper shows the experimental results of a didactical activity conducted using the motion sensor. This MBL-tool (Microcomputers-Based Laboratory) allows to study rectilinear motion of bodies moving in front of it. In a fixed time interval the motion sensor reveals the distance of bodies from it and transmits the measures to a computer that visualizes the data in tabular and Cartesian representations. This research corroborates several works about the use of MBL-tools, according to which the use of the motion sensor allows the students to read, understand and produce kinematics graphs. Moreover our analysis shows that the students acquire these competence respect to graphs of other type …
