Evaluación de la desaturación regional cerebral de oxígeno monitorizada mediante oximetría cerebral INVOS como método de detección de isquemia cerebr…

2022

Hipótesis: La monitorización de la saturación cerebral regional de oxígeno con el oxímetro INVOS- 5100 es eficaz en la detección de la isquemia cerebral intraoperatoria en la endarterectomía carotídea. Objetivo principal: Evaluar la oximetría cerebral INVOS como método de detección de isquemia cerebral en la cirugía carotídea. Para ello, se comparará el descenso en la saturación cerebral regional de oxígeno INVOS en el grupo de pacientes que presente clínica neurológica en el clampaje carotídeo con el grupo que permanece sin clínica. Objetivos secundarios: 1. Establecer un valor crítico de desaturación cerebral INVOS, absoluto y porcentual, a partir del cual aparece clínica neurológica y es…

An efficient method for selective oxidation of (oxime)Pt(II) to (oxime)Pt(IV) species using N,N-dichlorotosylamide

2016

The oxidation of (oxime)PtII species using the electrophilic chlorine-based oxidant N,N-dichlorotosylamide (4-CH3C6H4SO2NCl2) was studied. The reactions of trans-[PtCl2(oxime)2] (where oxime = acetoxime, cyclopentanone oxime, or acetaldoxime) with this oxidant led to trans-[PtCl4(oxime)2] products. The oxidation of trans-[Pt(o-OC6H4CH = NOH)2] at room temperature gave trans-[PtCl2(o-OC6H4CH = NOH)2], whereas the same reaction upon heating was accompanied by electrophilic substitution of the benzene rings. peerReviewed

Estudio de validación de pulsioximetría como método diagnóstico no invasivo de atelectasias tras anestesia general

2017

Introducción. Las complicaciones pulmonares postoperatorias son una entidad muy frecuente tras una anestesia general, llegando a diagnosticarse hasta en el 20 % de los pacientes. Sin embargo, se piensa que este porcentaje está infraestimado debido a que se requieren técnicas de imagen para el diagnóstico y el uso de fracciones inspiratorias de oxígeno altas. Estas complicaciones, en concreto las atelectasias, disminuyen la presión arterial de oxígeno causando hipoxemia. Esto conlleva un aumento de la morbimortalidad de los pacientes, pudiendo reagudizar las patologías de base y favoreciendo la aparición de otras complicaciones. Por ello, es necesario determinar un método de diagnóstico senc…

(E)-1-(Pyridin-4-yl)propan-1-one oxime

2016

The asymmetric unit of the title compound, C8H10N2O, contains two crystallographically independent molecules of slightly different conformation, which are linkedviaan intermolecular O—H...N hydrogen bond. The dihedral angle between the pyridine ring and the oxime plane of moleculeA[2.09 (19)°] is smaller than in moleculeB[16.50 (18)°].

(E)-1-(Pyridin-4-yl)propan-1-one O-tosyl oxime

2017

The title compound, C15H16N2O3S, was obtained by the reaction of (E)-1-(pyridin-4-yl)propan-1-one oxime andpara-toluenesulfonic acid. The pyridine ring makes a dihedral angle of 54.70 (10)° with the benzene ring. In the crystal, molecules are linked by C—H...O hydrogen bonds, forming a chain along thec-axis direction.

Sleep Disturbances in COPD are Associated with Heterogeneity of Airway Obstruction

2018

Individuals with Chronic Obstructive Pulmonary Disease (COPD) experience sleep disturbances due to the impact of respiratory symptoms on sleep quality. We explored whether sleep disturbances in COPD are linked to heterogeneity of airway constriction.The impact of breathing problems on sleep quality was measured in consecutive COPD outpatients with the COPD and Asthma Sleep Impact Scale (CASIS) questionnaire. Impulse oscillometry technique (IOS) was employed to assess heterogeneity of airway constriction. Subjects with a previous or concomitant diagnosis of asthma or obstructive sleep apnea (OSA) were excluded.Fifty COPD subjects (M/F 40/10; age: 71 +/- 8 yrs, Body Mass Index (BMI): 26.2 +/-…

Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy

2015

ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.
