SEDAR/SECCE ECMO management consensus document.

ECMO is an extracorporeal cardiorespiratory support system whose use has been increased in the last decade. Respiratory failure, postcardiotomy shock, and lung or heart primary graft failure may require the use of cardiorespiratory mechanical assistance. In this scenario perioperative medical and surgical management is crucial. Despite the evolution of technology in the area of extracorporeal support, morbidity and mortality of these patients continues to be high, and therefore the indication as well as the ECMO removal should be established within a multidisciplinary team with expertise in the area. This consensus document aims to unify medical knowledge and provides recommendations based on both the recent bibliography and the main national ECMO implantation centres experience with the goal of improving comprehensive patient care.

Efecto de la variabilidad glucémica intrahospitalaria en la mortalidad de los pacientes con diabetes / Effect of in-hospital glycemic variability on mortality in patients with diabetes

Introducción El objectivo fue evaluar la importancia de glucemia media (GM) y variabilidad glucémica (VG) durante la hospitalización sobre la mortalidad tras el alta.Material y métodosEstudio de cohortes retrospectivo longitudinal analítico. Se incluyeron pacientes dados de alta del Servicio de Medicina Interna con algún diagnóstico relacionado con la diabetes. El pronóstico evaluado fue la mortalidad. Se recogieron durante el ingreso variables clínicas, analíticas y relacionadas con el control glucémico hospitalario (GM, VG e hipoglucemias). La VG se midió con el coeficiente de variación (CV).Se calcularon las tasas de mortalidad por cada 1000 pacientes-año y se compararon con curvas de Kaplan-Meier. La determinación de los factores predictivos de mortalidad se realizó mediante regresión de Cox.ResultadosSe incluyeron 276 pacientes con edad media 77,6 (DE 10,2) años. La duración mediana del seguimiento extrahospitalario fue de 2,7 años.En análisis multivariante, una GM > 140 (HR=1,72; IC 95% 1,14-2,61; p=0,01) y un CV > 0,29 (HR=1,52; IC 95% 1,12-2,06; p=0,006), no así la presencia de hipoglucemias, se asociaron a incremento del riesgo de mortalidad de forma aditiva e independiente. Tener una GM > 140 simultáneamente con un CV > 0,29 incrementó las tasas de mortalidad (123 vs. 317 por 1.000 pacientes-año; p <0,001) y el riesgo ajustado de mortalidad (HR=2,70; IC 95% 1,71-4,27; p<0,001) respecto a tener una GM ≤ 140mg/dl.ConclusiónLa presencia simultánea de GM y VG elevadas constituye una potente herramienta de estratificación del riesgo de mortalidad tras el alta hospitalaria.

Inhibition of α-amylase by flavonoids: Structure activity relationship (SAR).

Flavonoids are recognized to regulate animals' food digestion processes trough interaction with digestive enzymes. The binding capacity of hesperetin (HES), luteolin (LUT), quercetin (QUE), catechin (CAT) and rutin (RUT) with pancreatic α-amylase were evaluated, using UV-Vis spectroscopy, fluorescence and molecular docking. Using p-nitrophenyl-α-d-maltopentoside (pNPG5) as substrate analog, LUT showed the best inhibitory capacity, even better than that of the positive control, acarbose (ACA). A mixed-type inhibition was observed for HES, LUT and QUE, a competitive-type for ACA, while no inhibition was observed with CAT and RUT. In agreement with kinetic results, α-amylase presented a higher affinity for LUT, when analyzed by fluorescence quenching. The binding of flavonoids to amylase followed a static mechanism, where the binding of one flavonoid per enzyme molecule was observed. Docking analysis showed that flavonoids bound near to enzyme active site, while ACA bound in another site behind the catalytic triad. Extrinsic fluorescence analysis, together with docking analysis pointed out that hydrophobic interactions regulated the flavonoid-α-amylase interactions. The present study provides evidence to understand the relationship of flavonoids structure with their inhibition mechanism.

Evidence supporting the best clinical management of patients with multimorbidity and polypharmacy: a systematic guideline review and expert consensus.

The complexity and heterogeneity of patients with multimorbidity and polypharmacy renders traditional disease-oriented guidelines often inadequate and complicates clinical decision making. To address this challenge, guidelines have been developed on multimorbidity or polypharmacy. To systematically analyse their recommendations, we conducted a systematic guideline review using the Ariadne principles for managing multimorbidity as analytical framework. The information synthesis included a multistep consensus process involving 18 multidisciplinary experts from seven countries. We included eight guidelines (four each on multimorbidity and polypharmacy) and extracted about 250 recommendations. The guideline addressed (i) the identification of the target population (risk factors); (ii) the assessment of interacting conditions and treatments: medical history, clinical and psychosocial assessment including physiological status and frailty, reviews of medication and encounters with healthcare providers highlighting informational continuity; (iii) the need to incorporate patient preferences and goal setting: eliciting preferences and expectations, the process of shared decision making in relation to treatment options and the level of involvement of patients and carers; (iv) individualized management: guiding principles on optimization of treatment benefits over possible harms, treatment communication and the information content of medication/care plans; (v) monitoring and follow-up: strategies in care planning, self-management and medication-related aspects, communication with patients including safety instructions and adherence, coordination of care regarding referral and discharge management, medication appropriateness and safety concerns. The spectrum of clinical and self-management issues varied from guiding principles to specific recommendations and tools providing actionable support. The limited availability of reliable risk prediction models, feasible interventions of proven effectiveness and decision aids, and limited consensus on appropriate outcomes of care highlight major research deficits. An integrated approach to both multimorbidity and polypharmacy should be considered in future guidelines.

Impact of noise in holography with extended references in the low signal regime.

Signal-to-noise ratio is a key factor in lensless imaging, particularly for low diffraction signal experiments in the single shot regime. We present our recent study of the noise impact on holography with extended references. Experimental data have been measured in single shot acquisition using an intense coherent soft X-ray high harmonic source. The impact of hardware and software noise under various detection conditions is discussed. A final comparison between single shot and multi-shot regimes is given.

Fourier transform holography with high harmonic spectra for attosecond imaging applications.

We demonstrate a method of using a Fourier holographic technique to utilize attosecond soft x-ray pulses to image nanometer-scale objects. A discrete frequency comb of laser-generated high-order harmonics, yielding a train of attosecond pulses, has been used to record spatially and spectrally resolved images. The individual wavelengths were also combined to form a single image, albeit with lower spatial resolution, demonstrating the applicability of the method to using isolated attosecond pulses with continuous bandwidths.

Cost analysis of an integrated vaccine-preventable disease surveillance system in Costa Rica.

INTRODUCTION: Following World Health Organization recommendations set forth in the Global Framework for Immunization Monitoring and Surveillance, Costa Rica in 2009 became the first country to implement integrated vaccine-preventable disease (iVPD) surveillance, with support from the U.S. Centers for Disease Control and Prevention (CDC) and the Pan American Health Organization (PAHO). As surveillance for diseases prevented by new vaccines is integrated into existing surveillance systems, these systems could cost more than routine surveillance for VPDs targeted by the Expanded Program on Immunization. OBJECTIVES: We estimate the costs associated with establishing and subsequently operating the iVPD surveillance system at a pilot site in Costa Rica. METHODS: We retrospectively collected data on costs incurred by the institutions supporting iVPD surveillance during the preparatory (January 2007 through August 2009) and implementation (September 2009 through August 2010) phases of the iVPD surveillance project in Costa Rica. These data were used to estimate costs for personnel, meetings, infrastructure, office equipment and supplies, transportation, and laboratory facilities. Costs incurred by each of the collaborating institutions were also estimated. RESULTS: During the preparatory phase, the estimated total cost was 128,000 U.S. dollars (US$), including 64% for personnel costs. The preparatory phase was supported by CDC and PAHO. The estimated cost for 1 year of implementation was US$ 420,000, including 58% for personnel costs, 28% for laboratory costs, and 14% for meeting, infrastructure, office, and transportation costs combined. The national reference laboratory and the PAHO Costa Rica office incurred 64% of total costs, and other local institutions supporting iVPD surveillance incurred the remaining 36%. CONCLUSIONS: Countries planning to implement iVPD surveillance will require adequate investments in human resources, laboratories, data management, reporting, and investigation. Our findings will be valuable for decision makers and donors planning and implementing similar strategies in other countries.

Impact of wave front and coherence optimization in coherent diffractive imaging.

We present single shot nanoscale imaging using a table-top femtosecond soft X-ray laser harmonic source at a wavelength of 32 nm. We show that the phase retrieval process in coherent diffractive imaging critically depends on beam quality. Coherence and image fidelity are measured from single-shot coherent diffraction patterns of isolated nano-patterned slits. Impact of flux, wave front and coherence of the soft X-ray beam on the phase retrieval process and the image quality are discussed. After beam improvements, a final image reconstruction is presented with a spatial resolution of 78 nm (half period) in a single 20 fs laser harmonic shot.

[Study of the nutritional status of elders in Cantabria]. / Estudio del estado nutricional de los ancianos de Cantabria.

INTRODUCTION: Population ageing is a main concern under the biosanitary point of view. AIM: To assess the nutritional status of people 65 year-old and older in Cantabria (Spain) METHOD: A total of 1605 persons were studied by means of the MNA (Mini Nutritional Assessment); a) by primary care (59.9% in the unit, and 4.7% at home) and, b) in nursing homes (35.4%). RESULTS: Nutritional score (NS) was 23.4 ± 4.1 for women and 24.4 ± 4 in males (p < 0.001). We emphasize the fact that 22.3% of people studied in the nursing homes were malnourished or at risk of malnutrition, compared with 14.2% of those studied at the unit, and only 3.3% of the home visited elders. The correlation between the value of the NS and the subjective estimation of nutrition status showed a high value (0.65). We emphasize the negative correlation (-0.53) between BNI value and the incidence of skin lesions. CONCLUSION: Our results highlight the importance of identifying malnutrition or its risk in elders in order to prevent the negative consequences of this deficiency.

Tularemia: a propósito de un caso en Miranda de Ebro, Burgos / Tularemia: a case report in Miranda de Ebro, Burgos

La tularemia es una de las infecciones emergentes de nuestros días. F. tularensis es un patógeno muy virulento, capaz de iniciar la infección tan sólo con la inoculación de 10 microorganismos. A pesar de que no es una infección frecuente en las consultas de Atención Primaria, es importante su sospecha para realizar un diagnóstico precoz y así adelantarnos a la aparición de nuevos brotes y adoptar oportunas medidas de control (AU)

Tularemia is one of the emerging infections of our times. F. tularensis is a highly virulent pathogen that is capable of initiating the infection with only the inoculation of 10 microorganisms. Although it is not a frequent infection seen in Primary Care consultations, it is important to diagnosis it early and thus anticipate the emergence of new outbreaks and adopt appropriate measures to control it (AU)

Microbiological analysis of cryopreserved human heart valves after storage: a survey of 3 banks in Spain.

Several reports have shown liquid nitrogen containers as not being sterile. Microorganism transmission has been observed in different cells and tissues stored under this condition, but there is no data on contamination of stored human valves. We performed a survey on heart valve banking in Spain. Regarding the questionnaire, we have a complete microbiological analysis of 304 thawed tissues prior to implant. In six cases positive culture results were observed. Patient follow-up did not reveal any adverse effects. Although some other possibilities should be stated, contamination of heart valves during storage in liquid nitrogen should be considered as a risk element in tissue banking. Strategies to asses and prevent microbial transmission from liquid nitrogen to heart valve banking ought to be further developed.

Chlorobenzene, chloroform, and carbon tetrachloride adsorption on undoped and metal-doped sol-gel substrates (SiO(2), Ag/SiO(2), Cu/SiO(2) and Fe/SiO(2)).

Adsorption isotherms of chlorobenzene, chloroform and carbon tetrachloride vapors on undoped SiO(2), and metal-doped Ag/SiO(2), Cu/SiO(2) and Fe/SiO(2) substrates were measured in the temperature range of 398-593K. These substrates were prepared from a typical sol-gel technique in the presence of metal dopants that rendered an assortment of microporous-mesoporous solids. The relevant characteristic of these materials was the different porosities and micropore to mesopore volume ratios that were displayed; this was due to the effect that the cationic metal valence exerts on the size of the sol-gel globules that compose the porous solid. The texture of these SiO(2) materials was analyzed by X-ray diffraction (XRD), FTIR, and diverse adsorption methods. The pore-size distributions of the adsorbents confirmed the existence of mesopores and supermicropores, while ultramicropores were absent. The Freundlich adsorption model approximately fitted the chlorinated compounds adsorption data on the silica substrates by reason of a heterogeneous energy distribution of adsorption sites. The intensity of the interaction between these organic vapors and the surface of the SiO(2) samples was analyzed through evaluation of the isosteric heat of adsorption and standard adsorption energy; from these last results it was evident that the presence of metal species within the silica structure greatly affected the values of both the amounts adsorbed as well as of the isosteric heats of adsorption.

[Brain natriuretic peptide in primary care: diagnostic value in heart failure]. / Péptido cerebral natriurético en atención primaria: valor diagnóstico en la insuficiencia cardíaca.

OBJECTIVE: To determine the validity and usefulness of brain natriuretic peptide (BNP) for diagnosing left ventricular dysfunction (LVD). DESIGN: Prospective, descriptive, multi-centred study to validate the diagnostic test. SETTING: Primary care centres in the Community of Madrid, Spain. PARTICIPANTS: Consecutive sample of patients at high risk of presenting with LVD. INTERVENTIONS: Data will be gathered from anamnesis, physical examination, ECG, and chest x-ray to find the risk factor(s) for LVD and the presence or absence of symptoms of congestive heart failure according to the Framingham scale. BNP will be determined at PC clinics in all patients who meet the inclusion criteria, using the "triage BNP test." All patients included in the study will be referred to an echocardiography service for an echocardiogram, which will be the gold standard test. Two independent cardiologists will evaluate the echocardiograph without knowing the BNP values. MAIN MEASUREMENTS: BNP concentrations will be compared against the kind and degree of LVD. ROC curves analysis will test the capacity of BNP to diagnose LVD. Optimal sensitivity and specificity value will be calculated by means of the position on the curve resulting from the minimum distance at the cut-off point for best sensitivity and specificity. Then, sensitivity, specificity, and positive and negative predictive values will be calculated. DISCUSSION: BNP can complement the information provided by other diagnostic tests. It should be included as an important factor in the taking of clinical-therapeutic decisions.
