Evaluación de una herramienta educativa en conocimiento de donación y trasplante de órganos y tejidos en Colombia

El trasplante de órganos es considerado uno de los avances más significativos de la medicina moderna y es un procedimiento cada vez más exitoso en términos de supervivencia de los pacientes, siendo actualmente la mejor opción de tratamiento para los pacientes con innumerables patologías. El proceso de donación es insuficiente para cubrir las necesidades de trasplante de la población, por lo tanto, se hace necesario el desarrollo de nuevas estrategias para fortalecer la experiencia y efectividad de los programas existentes. La falta de conocimiento de los profesionales de la salud, su percepción y actitud hacia temas relacionados con el proceso de donación, pueden convertirlos en facilitadores o barreras para la identificación de potenciales donantes. Por esta razón, los recursos disponibles, las actitudes hacia la donación, la legislación y conocimiento de los procesos involucrados en la donación de tejidos y órganos son críticos. Dada la influencia de los profesionales de salud se definen los objetivos de este proyecto de tesis: determinar cuál es el conocimiento y las habilidades de los profesionales de la salud encargados de los trasplantes de órganos y de tejidos en la regional 1, evaluados mediante una herramienta educativa para contribuir a mejorar un programa eficiente de Donación de Órganos y tejidos y así mismo, fijar recomendaciones en aras de aumentar las tasas de donación, con especial énfasis en la actividad hospitalaria en el país. METODOLOGIA Se realizó un estudio basado en el análisis de la evaluación de conocimientos del proceso donación- trasplante de órganos y tejidos en el personal de salud participante en la herramienta educativa llamada “Curso taller primer respondiente del potencial donante de órganos y tejidos”. Este curso incluía un formato evaluativo que fue diligenciado de manera anónima por los participantes antes y después de recibir el contenido del curso. El estudio se desarrolló en personal de la Salud de IPS pertenecientes a la Regional I, de la Red Nacional de donación y trasplantes de órganos y tejidos. Con el fin de evidenciar si existen diferencias en el conocimiento de los participantes del curso antes y después de asistir al mismo, se utilizó la prueba de McNemar (p< 0.05). RESULTADOS Entre julio del 2011 y junio del 2012, se realizó el “Curso taller primer respondiente del potencial donante de órganos y tejidos” y se obtuvieron 303 encuestados incluidos médicos, enfermeras y auxiliares de enfermería. Al inicio del curso las respuestas acertadas con relación a legislación, selección del donante, muerte encefálica y mantenimiento del donante estuvieron alrededor del 50%. No fue posible detectar la profesión que pudiese generar riesgo en la detección del donante y los procesos asociados. Posterior al curso, el 72% de las preguntas se respondieron de manera correcta, lo que representa un incremento estadísticamente significativo. Este cambio evidenció significancia estadística al usar la prueba de McNemar y arrojar un valor de p=0.00. .DISCUSIÓN El personal de salud participante en el curso taller proveniente de unidades involucradas como generadoras de donantes muestra un déficit de conocimientos del proceso donación trasplantes lo que puede convertirlos en limitantes para dicho proceso

Existen diferencias farmacocinéticas y tiempos de despertar entre mujeres y hombres con anestesia total intravenosa

Introducción: La anestesia total intravenosa (TIVA) es ampliamente usada y reportada en la literatura como técnica para disminuir la respuesta a la laringoscopia e intubación, en la inducción y mantenimiento de una adecuada anestesia, además de una mejor estabilidad hemodinámica y recuperación pos anestésica; sin embargo no existen un gran número de estudios que comparen el uso de TIVA, determinando si existen diferencias en el perfil farmacocinético según el género del paciente. Objetivo: Describir diferencias farmacocinéticas y de los tiempos de despertar y salida a la unidad de cuidados pos anestésicos (descarga), según el género; en pacientes que reciben TIVA, con remifentanil y propofol, orientado por Stangraf. Metodología: Estudio observacional analítico de corte transversal, en pacientes llevados a cirugía bajo TIVA en el Hospital Occidente de Kennedy en el periodo de junio de 2013 a Enero de 2014.Usando SPSS versión 20 Windows, se analizaron los datos mediante pruebas Kolmogorov-Smirnov y Shapiro-Wilk y U de Mann Withney. Un valor de p menor 0.05 fue aceptado como estadísticamente significativo. Resultados: Se aplicaron pruebas de normalidad y no se encontraron diferencias estadísticamente significativas entre género. El tiempo de despertar fue 9.36 minutos para mujeres y 11.26 minutos para hombres. Los tiempos de descarga fueron 10.71 minutos para mujeres y 12.82 minutos para hombres. Discusión. El tiempo de despertar y descarga no es diferente entre mujeres y hombres en los pacientes analizados. Se requieren estudios adicionales entre grupos poblacionales de diversas condiciones farmacocineticas para corroborar los datos.

Factores relacionados con la tasa de hospitalización en pacientes con enfermedades cardiovasculares en tres instituciones de salud. Bogotá, 2011 – 2013

Introducción: Las enfermedades cardiovasculares constituyen uno de los principales obstáculos para el desarrollo del siglo XXI, según la OMS en el año 2008 fueron responsables del 30% de las muertes registradas en todo el mundo. Aunque la diabetes mellitus no se encuentra dentro de la clasificación establecida por la OMS de este grupo de enfermedades, consideramos importante su mención e inclusión dentro de nuestro estudio por el alto número de pacientes con esta enfermedad que cursa con complicaciones cardiovasculares asociadas. Metodología: Estudio de casos y controles seleccionados con un muestreo aleatorio simple con 80 casos y 80 controles apareados por edad y género, entre los cuales se encuentran 91 hombres y 60 mujeres, realizando un análisis estadístico univariado y multivariado para este tipo de estudios. Resultados: Los años de consumo de cigarrillo tuvieron una asociación con la ocurrencia del evento con un OR de 0.95 (intervalo de confianza (IC) del 95%, 0.91 – 0.99) y la asistencia a controles con especialidades de competencia cardiovascular la asociación del evento reporto un OR de 6,49 con un IC del 95%, 2.38 – 17.6. Conclusiones: De acuerdo a los resultados se encuentra que los años de consumo de cigarrillo tiene una asociación con la hospitalización en paciente con ECV y la asistencia a consultas con especialidades de competencia cardiovascular una asociación positiva con la hospitalización en este grupo de pacientes, lo que nos indica que los paciente que más se hospitalizan podrían estar relacionados con una mayor complejidad de sus patologías.

salud financiera y riesgo en los estados financieros de la empresa avianca del sector aeronautico

La globalización y la competitividad como realidad de las empresas, implica que los gerentes preparen a sus empresas de la mejor manera para sobrevivir en este mundo tan inestable y cambiante. El primer paso consta de investigar y medir como se encuentra la empresa en cada uno de sus componentes, tales como recurso humano, mercadeo, logística, operación y por último y más importante las finanzas. El conocimiento de salud financiera y de los riesgos asociados a la actividad de las empresas, les permitirá a los gerentes tomar las decisiones correctas para ser rentables y perdurables en el mundo de los negocios inmerso en la globalización y competitividad. Esta apreciación es pertinente en Avianca S.A. esto teniendo en cuenta su progreso y evolución desde su primer vuelo el 5 de diciembre de 1919 comercial, hasta hoy cuando cotiza en la bolsa de Nueva York. Se realizó un análisis de tipo descriptivo, acompañado de la aplicación de ratios y nomenclaturas, dando lugar a establecer la salud financiera y los riesgos, no solo de Avianca sino también del sector aeronáutico. Como resultado se obtuvo que el sector aeronáutico sea financieramente saludable en el corto plazo, pero en el largo plazo su salud financiera se ve comprometida por los riegos asociados al sector y a la actividad desarrollada.

Supervivencia en pacientes con trasplante hepático realizado en la Fundación Cardioinfantil entre 2005 y 2013

Introducción: El trasplante hepático es la terapia de elección para los pacientes con enfermedad hepática terminal, logrando mejorar su expectativa y calidad de vida, de acuerdo a estudios realizados en otros países. En la Fundación Cardioinfantil – Instituto de Cardiología (FCI-IC) se han realizado 332 trasplantes hepáticos hasta el 2014, pero no se conoce la supervivencia y los factores pronósticos propios de los pacientes intervenidos. Objetivo Principal: Estimar la supervivencia a 1, 3 y 5 años e identificar los principales factores pronósticos de los pacientes a quienes se les realizó trasplante hepático en el periodo 2005-2013 en la FCI-IC. Método: Estudio observacional y retrospectivo, basado en revisión de historias clínicas de los pacientes adultos a quienes se les realizó trasplante hepático en el periodo 2005-2013 en la FCI-IC. Resultados: La supervivencia al año fue de 90.91% (IC95% 86.40-93.98), a los 3 años 83.64% (IC95% 77.89-88.01) y a los 5 años de 79.18% (IC95% 72.54-84.39). Los principales factores pronósticos fueron el antecedente de ascitis (HR 2.449, IC 1.252 – 4.792), la edad del donante (HR 1.040, IC 1.009 – 1.071) y el receptor (HR 1.037, IC 1.014 – 1.060). Se encontró una mayor supervivencia en los pacientes con cirrosis alcohólica (HR 0.099, IC 0.021 – 0.467). Conclusiones: El estudio mostró una supervivencia mayor a la reportada en estudios realizados en Estados Unidos (67.4-73.0% a los 5 años) y España (73,3% a los 3 años) y similar a la de Chile (80.0% a los 5 años). Cabe resaltar que estos estudios incluyeron series más grandes de pacientes.

Secuenciación de siguiente generación en mujeres afectadas por falla ovárica prematura no sindrómica para la identificación de nuevos genes etiológicos de la enfermedad y estudio funcional de la mutación p.thr943ile en adamts19

La infertilidad afecta en la actualidad a aproximadamente 1 de cada 7 parejas a nivel mundial. La falla ovárica prematura (FOP) es una condición común en la población femenina, afectando al 1% de mujeres menores de 40 años. La etiología de la FOP es idiopática entre el 50% y el 80% de los casos, lo que sugiere causas genéticas, epigenéticas y ambientales aún desconocidas. A pesar de los avances en las técnicas de cartografía genética y de sistematización de la técnica de Sanger, pocos genes etiológicos de FOP fueron identificados en los últimos 20 años. Este fracaso relativo se asoció principalmente a que cientos de genes, que abarcan grandes regiones del genoma, son candidatos pero la técnica de secuenciación directa sólo permite el análisis de unas 700bp en cada reacción. En el presente trabajo se empleó la secuenciación de siguiente generación (NGS) para la búsqueda de mutaciones en 70 genes candidatos que potencialmente contribuyen con el desarrollo de la patología. Se identificaron mutaciones en 3 de 12 pacientes. La paciente POF-7 presentaba una mutación no sinónima en el gen ADAMTS19 (c.2828C>T, p.Thr943Ile). La proteína ADAMTS19 se clasifica dentro de la familia ADAMTS como huérfana ya que no se ha identificado su sustrato. Mediante el sistema de doble hibrido en levaduras se buscó identificar las potenciales proteínas que interactúan con ADAMTS19. Permitió identificar, a partir de las versiones murinas, la interacción de Adamts19 y Col6a2. Para comprobar la interacción entre las proteínas ADAMTS19 y COL6A2 humanas se empleó el sistema de doble hibrido en células eucariotas. Los hallazgos no permitieron replicar los resultados obtenidos previamente. En síntesis de identificó una mutación potencialmente causal de FOP en un gen nuevo y una muy probable interacción entre ADAMTS19 y COL6A2.

Obesity and health in Europeans aged 50 years and older

Background: Obesity is increasing globally across all population groups. Limited data are available on how obesity patterns differ across countries. Objective: To document the prevalence of obesity and related health conditions for Europeans aged 50 years and older, and to estimate the association between obesity and health outcomes across 10 European countries. Methods: Data were obtained from the 2004 Survey of Health, Ageing and Retirement in Europe, a cross-national survey of 22 777 Continental Europeans over the age of 50 years. The health outcomes included self-reported health, disability, doctor-diagnosed chronic health conditions and depression. Multivariate regression analysis was used to predict health outcomes across weight classes (defined by body mass index [BMI] from self-reported weight and height) in the pooled sample and individually in each country. Results: The prevalence of obesity (BMI >= 30) ranged from 12.8% in Sweden to 20.2% in Spain for men and from 12.3% in Switzerland to 25.6% in Spain for women. Adjusting for compositional differences across countries changed little in the observed large heterogeneity in obesity rates throughout Europe. Compared with normal weight individuals, men and women with greater BMI had significantly higher risks for all chronic health conditions examined except heart disease in overweight men. Depression was linked to obesity in women only. Particularly pronounced risks of impaired health and chronic health conditions were found among severely obese people. The effects of obesity on health did not vary significantly across countries. Conclusions: Cross-country differences in the prevalence of obesity in older Europeans are substantial and exceed socio-demographic differentials in excessive body weight. Obesity is associated with significantly poorer health outcomes among Europeans aged 50 years and over, with effects similar across countries. Large heterogeneity in obesity throughout Europe should be investigated further to identify areas for effective public policy.

Impact of age and menopausal status on the postprandial triacylglycerol response in healthy women

Objective: To examine the impact of age and the natural menopause on the postprandial triacylglycerol (TAG) response in healthy women. Methods and results: Thirty-seven premenopausal and sixty-one postmenopausal women underwent a sequential meal postprandial investigation, in which blood samples were taken at regular intervals after a test breakfast and lunch given at 0 and 330 min respectively. Lipids and glucose were measured in the fasting sample, with TAG analysed in the postprandial samples. Postmenopausal women were shown to have higher fasting total cholesterol, low density lipoprotein cholesterol (LDL-C) and glucose (P < 0.02). Marked differences in the postprandial TAG response were evident between the groups, with a greater incremental area under the curve (IAUC) and maximum TAG concentration in the postmenopausal women (P < 0.04). Multivariate regression analysis revealed both age and fasting TAG to be independently associated with the summary measures of the postprandial TAG response in the premenopausal women only. Interestingly, sub-division of the women into both younger and older pre- and postmenopausal subgroups, showed the most marked difference in TAG-IAUC to be between the younger and the older premenopausal women, whereas differences in fasting LDL-C were most evident between the older premenopausal and the younger postmenopausal women. Conclusions: Our results suggest a divergence in the relationship of age and menopausal status with fasting LDL-C and postprandial TAG which may reflect differences in the metabolic effects of age and the menopause on these lipid risk markers or a greater impact of early oestrogen decline on pathways of TAG rather than LDL metabolism.

Energy and protein interactions and their effect on nitrogen excretion in dairy cows

The principal driver of nitrogen (N) losses from the body including excretion and secretion in milk is N intake. However, other covariates may also play a role in modifying the partitioning of N. This study tests the hypothesis that N partitioning in dairy cows is affected by energy and protein interactions. A database containing 470 dairy cow observations was collated from calorimetry experiments. The data include N and energy parameters of the diet and N utilization by the animal. Univariate and multivariate meta-analyses that considered both within and between study effects were conducted to generate prediction equations based on N intake alone or with an energy component. The univariate models showed that there was a strong positive linear relationships between N intake and N excretion in faeces, urine and milk. The slopes were 0.28 faeces N, 0.38 urine N and 0.20 milk N. Multivariate model analysis did not improve the fit. Metabolizable energy intake had a significant positive effect on the amount of milk N in proportion to faeces and urine N, which is also supported by other studies. Another measure of energy considered as a covariate to N intake was diet quality or metabolizability (the concentration of metabolizable energy relative to gross energy of the diet). Diet quality also had a positive linear relationship with the proportion of milk N relative to N excreted in faeces and urine. Metabolizability had the largest effect on faeces N due to lower protein digestibility of low quality diets. Urine N was also affected by diet quality and the magnitude of the effect was higher than for milk N. This research shows that including a measure of diet quality as a covariate with N intake in a model of N execration can enhance our understanding of the effects of diet composition on N losses from dairy cows. The new prediction equations developed in this study could be used to monitor N losses from dairy systems.

Greater impairment of postprandial triacylglycerol than glucose response in metabolic syndrome subjects with fasting hyperglycaemia

Abstract Objective: Studies have started to question whether a specific component or combinations of metabolic syndrome (MetS) components may be more important in relation to cardiovascular disease risk. Our aim was to examine the impact of the presence of raised fasting glucose as a MetS component on postprandial lipaemia. Methods: Men classified with the MetS underwent a sequential test meal investigation, in which blood samples were taken at regular intervals after a test breakfast (t=0 min) and lunch (t=330 min). Lipids, glucose and insulin were measured in the fasting and postprandial samples. Results: MetS subjects with 3 or 4 components were subdivided into those without (n=34) and with (n=23) fasting hyperglycaemia (≥ 5.6 mmol/l), irrespective of the combination of components. Fasting lipids and insulin were similar in the two groups, with glucose significantly higher in the men with glucose as a MetS component (P<0.001). Following the test meals, there was a higher maximum concentration (maxC), area under the curve (AUC) and incremental AUC (P≤0.016) for the postprandial triacylglycerol (TAG) response in men with fasting hyperglycaemia. Greater glucose AUC (P<0.001) and insulin maxC (P=0.010) was also observed in these individuals after the test meals. Multivariate regression analysis revealed fasting glucose to be an important predictor of the postprandial TAG and glucose response. Conclusion: Our data analysis has revealed a greater impairment of postprandial TAG than glucose response in MetS subjects with raised fasting glucose. The worsening of postprandial lipaemic control may contribute to the greater CVD risk reported in individuals with MetS component combinations which include hyperglycaemia.

Hydrophilic interaction chromatography–mass spectrometry for anionic metabolic profiling of urine from antibiotic-treated rats

Hydrophilic interaction chromatography–mass spectrometry (HILIC–MS) was used for anionic metabolic profiling of urine from antibiotic-treated rats to study microbial–host co-metabolism. Rats were treated with the antibiotics penicillin G and streptomycin sulfate for four or eight days and compared to a control group. Urine samples were collected at day zero, four and eight, and analyzed by HILIC–MS. Multivariate data analysis was applied to the urinary metabolic profiles to identify biochemical variation between the treatment groups. Principal component analysis found a clear distinction between those animals receiving antibiotics and the control animals, with twenty-nine discriminatory compounds of which twenty were down-regulated and nine up-regulated upon treatment. In the treatment group receiving antibiotics for four days, a recovery effect was observed for seven compounds after cessation of antibiotic administration. Thirteen discriminatory compounds could be putatively identified based on their accurate mass, including aconitic acid, benzenediol sulfate, ferulic acid sulfate, hippuric acid, indoxyl sulfate, penicillin G, phenol and vanillin 4-sulfate. The rat urine samples had previously been analyzed by capillary electrophoresis (CE) with MS detection and proton nuclear magnetic resonance (1H NMR) spectroscopy. Using CE–MS and 1H NMR spectroscopy seventeen and twenty-five discriminatory compounds were found, respectively. Both hippuric acid and indoxyl sulfate were detected across all three platforms. Additionally, eight compounds were observed with both HILIC–MS and CE–MS. Overall, HILIC–MS appears to be highly complementary to CE–MS and 1H NMR spectroscopy, identifying additional compounds that discriminate the urine samples from antibiotic-treated and control rats.

The development of soil organic matter in restored biodiverse Jarrah forests of South-Western Australia as determined by ASE and GCMS

Background, aim and scope Soil organic matter (SOM) is known to increase with time as landscapes recover after a major disturbance; however, little is known about the evolution of the chemistry of SOM in reconstructed ecosystems. In this study, we assessed the development of SOM chemistry in a chronosequence (space for time substitution) of restored Jarrah forest sites in Western Australia. Materials and methods Replicated samples were taken at the surface of the mineral soil as well as deeper in the profile at sites of 1, 3, 6, 9, 12, and 17 years of age. A molecular approach was developed to distinguish and quantify numerous individual compounds in SOM. This used accelerated solvent extraction in conjunction with gas chromatography mass spectrometry. A novel multivariate statistical approach was used to assess changes in accelerated solvent extraction (ASE)-gas chromatography-mass spectrometry (GCMS) spectra. This enabled us to track SOM developmental trajectories with restoration time. Results Results showed total carbon concentrations approached that of native forests soils by 17 years of restoration. Using the relate protocol in PRIMER, we demonstrated an overall linear relationship with site age at both depths, indicating that changes in SOM chemistry were occurring. Conclusions The surface soils were seen to approach native molecular compositions while the deeper soil retained a more stable chemical signature, suggesting litter from the developing diverse plant community has altered SOM near the surface. Our new approach for assessing SOM development, combining ASE-GCMS with illuminating multivariate statistical analysis, holds great promise to more fully develop ASE for the characterisation of SOM.

Auriculo-condylar syndrome: mapping of a first locus and evidence for genetic heterogeneity

Auriculo-condylar syndrome (ACS), an autosomal dominant disorder of first and second pharyngeal arches, is characterized by malformed ears (`question mark ears`), prominent cheeks, microstomia, abnormal temporomandibular joint, and mandibular condyle hypoplasia. Penetrance seems to be complete, but there is high inter-and intra-familial phenotypic variation, with no evidence of genetic heterogeneity. We herein describe a new multigeneration family with 11 affected individuals (F1), in whom we confirm intra-familial clinical variability. Facial asymmetry, a clinical feature not highlighted in other ACS reports, was highly prevalent among the patients reported here. The gene responsible for ACS is still unknown and its identification will certainly contribute to the understanding of human craniofacial development. No chromosomal rearrangements have been associated with ACS, thus mapping and positional cloning is the best approach to identify this disease gene. To map the ACS gene, we conducted linkage analysis in two large ACS families, F1 and F2 (F2; reported elsewhere). Through segregation analysis, we first excluded three known loci associated with disorders of first and second pharyngeal arches (Treacher Collins syndrome, oculo-auriculo-vertebral spectrum, and Townes-Brocks syndrome). Next, we performed a wide genome search and we observed evidence of linkage to 1p21.1-q23.3 in F2 (LOD max 3.01 at theta = 0). Interestingly, this locus was not linked to the phenotype segregating in F1. Therefore, our results led to the mapping of a first locus of ACS (ACS1) and also showed evidence for genetic heterogeneity, suggesting that there are at least two loci responsible for this phenotype.

Cell wall polysaccharides from cell suspension cultures of the Atlantic Forest tree Rudgea jasminoides (Rubiaceae)

Rudgea jasminoides (Rubiaceae) is a tropical tree species native of the Atlantic Forest in the south of Brazil. Previous studies with leaf cell walls of R. jasminoides showed a different proportion of cross-linked glycans compared to what is usually reported for eudicots. However, due to the difficulties of working with whole plant organs, cell suspensions of R. jasminoides, consisting of predominantly undifferentiated cells with mainly primary cell walls, were used to examine cell walls and extracellular soluble polysaccharides (EP) released into the culture medium. Sugar composition and linkage analysis showed homogalacturonans, xylogalacturonans and arabinogalactans to be the predominant EP. In the cell wall, homogalacturonans and arabinogalactans are the major pectins, and xyloglucans and xylans are the major cross-linking glycans. The presence of xylogalacturonans in the R. jasminoides cell cultures seems to be related to the occurrence of a homogeneous cell suspension with loosely attached cells. Although all alkali extractions from the cell walls yielded amounts of xyloglucan that exceed those of the xylans, the latter was found in a proportion that is higher than what has been usually reported for primary cell walls of most eudicots. The xyloglucan from cell walls of cell suspension cultures of R. jasminoides has low fucosylation levels and high proportion of galactosyl residues, a branching pattern commonly found in storage cell-wall xyloglucans.

Metabolomic assessment with CE-MS of the nutraceutical effect of Cystoseira spp extracts in an animal model

There is a need of scientific evidence of claimed nutraceutical effects, but also there is a social movement towards the use of natural products and among them algae are seen as rich resources. Within this scenario, the development of methodology for rapid and reliable assessment of markers of efficiency and security of these extracts is necessary. The rat treated with streptozotocin has been proposed as the most appropriate model of systemic oxidative stress for studying antioxidant therapies. Cystoseira is a brown alga containing fucoxanthin and other carothenes whose pressure-assisted extracts were assayed to discover a possible beneficial effect on complications related to diabetes evolution in an acute but short-term model. Urine was selected as the sample and CE-TOF-MS as the analytical technique to obtain the fingerprints in a non-target metabolomic approach. Multivariate data analysis revealed a good clustering of the groups and permitted the putative assignment of compounds statistically significant in the classification. Interestingly a group of compounds associated to lysine glycation and cleavage from proteins was found to be increased in diabetic animals receiving vehicle as compared to control animals receiving vehicle (N6, N6, N6-trimethyl-L-lysine, N-methylnicotinamide, galactosylhydroxylysine, L-carnitine, N6-acetyl-N6-hydroxylysine, fructose-lysine, pipecolic acid, urocanic acid, amino-isobutanoate, formylisoglutamine. Fructoselysine significantly decreased after the treatment changing from a 24% increase to a 19% decrease. CE-MS fingerprinting of urine has provided a group of compounds different to those detected with other techniques and therefore proves the necessity of a cross-platform analysis to obtain a broad view of biological samples.
