Glucose tolerance and insulin resistance/sensitivity associate with retinal layer characteristics: the LIFE-Adult-Study.

AIMS/HYPOTHESIS: As the prevalence of insulin resistance and glucose intolerance is increasing throughout the world, diabetes-induced eye diseases are a global health burden. We aim to identify distinct optical bands which are closely related to insulin and glucose metabolism, using non-invasive, high-resolution spectral domain optical coherence tomography (SD-OCT) in a large, population-based dataset. METHODS: The LIFE-Adult-Study randomly selected 10,000 participants from the population registry of Leipzig, Germany. Cross-sectional, standardised phenotyping included the assessment of various metabolic risk markers and ocular imaging, such as SD-OCT-derived thicknesses of ten optical bands of the retina. Global and Early Treatment Diabetic Retinopathy Study (ETDRS) subfield-specific optical retinal layer thicknesses were investigated in 7384 healthy eyes of 7384 participants from the LIFE-Adult-Study stratified by normal glucose tolerance, prediabetes (impaired fasting glucose and/or impaired glucose tolerance and/or HbA1c 5.7-6.4% [39-47 mmol/mol]) and diabetes. The association of optical retinal band characteristics with different indices of glucose tolerance (e.g. fasting glucose, area under the glucose curve), insulin resistance (e.g. HOMA2-IR, triglyceride glucose index), or insulin sensitivity (e.g. estimated glucose disposal rate [eGDR], Stumvoll metabolic clearance rate) was determined using multivariable linear regression analyses for the individual markers adjusted for age, sex and refraction. Various sensitivity analyses were performed to validate the observed findings. RESULTS: In the study cohort, nine out of ten optical bands of the retina showed significant sex- and glucose tolerance-dependent differences in band thicknesses. Multivariable linear regression analyses revealed a significant, independent, and inverse association between markers of glucose intolerance and insulin resistance (e.g. HOMA2-IR) with the thickness of the optical bands representing the anatomical retinal outer nuclear layer (ONL, standardised ß=-0.096; p<0.001 for HOMA2-IR) and myoid zone (MZ; ß=-0.096; p<0.001 for HOMA2-IR) of the photoreceptors. Conversely, markers of insulin sensitivity (e.g. eGDR) positively and independently associated with ONL (ß=0.090; p<0.001 for eGDR) and MZ (ß=0.133; p<0.001 for eGDR) band thicknesses. These global associations were confirmed in ETDRS subfield-specific analyses. Sensitivity analyses further validated our findings when physical activity, neuroanatomical cell/tissue types and ETDRS subfield categories were investigated after stratifying the cohort by glucose homeostasis. CONCLUSIONS/INTERPRETATION: An impaired glucose homeostasis associates with a thinning of the optical bands of retinal ONL and photoreceptor MZ. Changes in ONL and MZ thicknesses might predict early metabolic retinal alterations in diabetes.

Evaluation of a portable retinal imaging device: towards a comparative quantitative analysis for morphological measurements of retinal blood vessels.

This study investigated the possibility of using low-cost, handheld, retinal imaging devices for the automatic extraction of quantifiable measures of retinal blood vessels. Initially, the available handheld devices were compared using a Zeiss model eye incorporating a USAF resolution test chart to assess their optical properties. The only suitable camera of the five evaluated was the Horus DEC 200. This device was then subjected to a detailed evaluation in which images in human eyes taken from the handheld camera were compared in a quantitative analysis with those of the same eye from a Canon CR-DGi retinal desktop camera. We found that the Horus DEC 200 exhibited shortcomings in capturing images of human eyes by comparison with the Canon. More images were rejected as being unevaluable or suffering failures in automatic segmentation than with the Canon, and even after exclusion of affected images, the Horus yielded lower measurements of vessel density than the Canon. A number of issues affecting handheld cameras in general and some features of the Horus in particular have been identified that might contribute to the observed differences in performance. Some potential mitigations are discussed which might yield improvements in performance, thus potentially facilitating use of handheld retinal imaging devices for quantitative retinal microvascular measurements.

Usefulness of intestinal ultrasound in inflammatory bowel disease. / Utilidad de la ecografía intestinal en la enfermedad inflamatoria intestinal.

Imaging techniques play a fundamental role in the initial diagnosis and follow-up of inflammatory bowel disease. Intestinal ultrasound has high sensitivity and specificity in patients with suspected Crohn's disease and in the detection of inflammatory activity. This technique enables the early diagnosis of intra-abdominal complications such as stenosis, fistulas, and abscesses. It has also proven useful in monitoring the response to treatment and in detecting postsurgical recurrence. Technical improvements in ultrasound scanners, technological advances such as ultrasound contrast agents and elastography, and above all increased experience have increased the role of ultrasound in the evaluation of the gastrointestinal tract. The features that make ultrasound especially attractive include its wide availability, its noninvasiveness and lack of ionizing radiation, its low cost, and its good reproducibility, which is important because it is easy to repeat the study and the study is well tolerated during follow-up. This review summarizes the role of intestinal ultrasound in the detection and follow-up of inflammatory bowel disease.

Bowel ultrasound: examination techniques and normal and pathologic patterns. / Ecografía intestinal: técnicas de examen, patrones normales y patológicos.

Ultrasound is being increasingly used to study the digestive tract because it has certain advantages over other techniques such as endoscopy, CT enterography, and MR enterography. Ultrasound can be used to evaluate the bowel wall and the elements that surround it without the need for contrast agents; its ability to evaluate the elasticity and peristalsis of these structures is increasing interest in its use. This article describes the techniques and modalities of bowel ultrasound, as well as the normal features of the bowel wall and contiguous structures. It uses a practical approach to review the main pathological findings and their interpretation, and the different patterns of presentation, which will help orient the diagnosis.

Magnetic vortex nucleation and annihilation in bi-stable ultra-small ferromagnetic particles.

Vortex-mediated magnetization reversal in individual ultra-small (∼100 nm) ferromagnetic particles at low temperatures is studied by nanoSQUID magnetometry. At zero applied bias field, the flux-closure magnetic state (vortex) and the quasi uniform configuration are bi-stable. This stems from the extremely small size of the nanoparticles that lies very close to the limit of single-domain formation. The analysis of the temperature-dependent (from 0.3 to 70 K) hysteresis of the magnetization allows us to infer the nature of the ground state magnetization configuration. The latter corresponds to a vortex state as also confirmed by electron holography experiments. Based on the simultaneous analysis of the vortex nucleation and annihilation data, we estimate the magnitude of the energy barriers separating the quasi single-domain and the vortex state and their field dependence. For this purpose, we use a modified power-law scaling of the energy barriers as a function of the applied bias field. These studies are essential to test the thermal and temporal stability of flux-closure states stabilized in ultra-small ferromagnets.

Automatic optic disc detection in colour fundus images by means of multispectral analysis and information content.

The optic disc (OD) in retinal fundus images is widely used as a reference in computer-based systems for the measurement of the severity of retinal disease. A number of algorithms have been published in the past 5 years to locate and measure the OD in digital fundus images. Our proposed algorithm, automatically: (i) uses the three channels (RGB) of the digital colour image to locate the region of interest (ROI) where the OD lies, (ii) measures the Shannon information content per channel in the ROI, to decide which channel is most appropriate for searching for the OD centre using the circular Hough transform. A series of evaluations were undertaken to test our hypothesis that using the three channels gives a better performance than a single channel. Three different databases were used for evaluation purposes with a total of 2,371 colour images giving a misdetection error of 3% in the localisation of the centre of the OD. We find that the area determined by our algorithm which assumes that the OD is circular, is similar to that found by other algorithms that detected the shape of the OD. Five metrics were measured for comparison with other recent studies. Combining the two databases where expert delineation of the OD is available (1,240 images), the average results for our multispectral algorithm are: TPR = 0.879, FPR = 0.003, Accuracy = 0.994, Overlap = 80.6% and Dice index = 0.878.

Conjugated linoleic acid and betaine affect lipolysis in pig adipose tissue explants.

Consumers' demand of leaner meat products is a challenge. Although betaine and conjugated linoleic acid (CLA) have the potential to decrease porcine adipose tissue, their mode of action is poorly understood. The aim of the study was to determine the lipolytic effect of betaine and CLA in the adipose tissue of Iberian pigs. Adipose tissue explants from five pigs (38 kg BW) were prepared from dorsal subcutaneous adipose tissue samples and cultivated for 2 h (acute experiments) or 72 h (chronic experiments). Treatments included 100 µM linoleic acid (control), 100 µM trans-10, cis-12 CLA, 100 µM linoleic acid + 1 mM betaine and 100 µM trans-10, cis-12 CLA + 1 mM betaine (CLABET). To examine the ability of betaine or CLA to inhibit insulin's suppression of isoproterenol-stimulated lipolysis, test medium was amended with 1 µM isoproterenol ±10 nM insulin. Media glycerol was measured at the end of the incubations. Acute lipolysis (2 h) was increased by CLA and CLABET (85% to 121%; P < 0.05) under basal conditions. When lipolysis was stimulated with isoproterenol (1090%), acute exposure to betaine tended to increase (13%; P = 0.071), while CLA and CLABET increased (14% to 18%; P < 0.05) isoproterenol-stimulated lipolysis compared with control. When insulin was added to isoproterenol-stimulated explants, lipolytic rate was decreased by 50% (P < 0.001). However, supplementation of betaine to the insulin + isoproterenol-containing medium tended to increase (P = 0.07), while CLABET increased (45%; P < 0.05) lipolysis, partly counteracting insulin inhibition. When culture was extended for 72 h, CLA decreased lipolysis under basal conditions (18%; P < 0.05) with no effect of betaine and CLABET (P > 0.10). When lipolysis was stimulated by isoproterenol (125% increase in rate compared with basal), CLA and CLABET decreased glycerol release (27%; P < 0.001) compared with control (isoproterenol alone). When insulin was added to isoproterenol-stimulated explants, isoproterenol stimulation of lipolysis was completely blunted and neither betaine nor CLA altered the inhibitory effect of insulin on lipolysis. Isoproterenol, and especially isoproterenol + insulin, stimulated leptin secretion compared with basal conditions (68% and 464%, respectively; P < 0.001), with no effect of CLA or betaine (P > 0.10). CLA decreased leptin release (25%; P < 0.001) when insulin was present in the media, partially inhibiting insulin stimulation of leptin release. In conclusion, betaine and CLA produced a biphasic response regarding lipolysis so that glycerol release was increased in acute conditions, while CLA decreased glycerol release and betaine had no effect in chronic conditions. Furthermore, CLA and CLABET indirectly increased lipolysis by reducing insulin-mediated inhibition of lipolysis during acute conditions.

NanoSQUID Magnetometry on Individual As-grown and Annealed Co Nanowires at Variable Temperature.

Performing magnetization studies on individual nanoparticles is a highly demanding task, especially when measurements need to be carried out under large sweeping magnetic fields or variable temperature. Yet, characterization under varying ambient conditions is paramount in order to fully understand the magnetic behavior of these objects, e.g., the formation of nonuniform states or the mechanisms leading to magnetization reversal and thermal stability. This, in turn, is necessary for the integration of magnetic nanoparticles and nanowires into useful devices, e.g., spin-valves, racetrack memories, or magnetic tip probes. Here, we show that nanosuperconducting quantum interference devices based on high critical temperature superconductors are particularly well suited for this task. We have successfully characterized a number of individual Co nanowires grown through focused electron beam induced deposition and subsequently annealed at different temperatures. Magnetization measurements performed under sweeping magnetic fields (up to ∼100 mT) and variable temperature (1.4-80 K) underscore the intrinsic structural and chemical differences between these nanowires. These point to significant changes in the crystalline structure and the resulting effective magnetic anisotropy of the nanowires, and to the nucleation and subsequent vanishing of antiferromagnetic species within the nanowires annealed at different temperatures.

Evaluation of upper tract urothelial carcinomas by contrast-enhanced ultrasound. / Valoración del carcinoma urotelial de vías superiores mediante ecografía con contraste.

AIM: To describe the findings and behaviour of contrast-enhanced ultrasound in the study of upper tract urothelial tumours and to assess its usefulness for diagnosis. MATERIAL AND METHODS: We reviewed our hospital's database over a period of 45 months to identify patients diagnosed with upper tract urothelial carcinomas. We reviewed the findings on mode B-ultrasound, contrast-enhanced ultrasound (location and qualitative assessment of intensity and washout of enhancement), and made a comparison with other techniques (computed tomography or magnetic resonance), and with the surgical specimen. RESULTS: We found 42 patients with a diagnosis of upper tract urothelial carcinoma confirmed with surgery over the period reviewed. Twenty-eight (67%) patients underwent contrast-enhanced ultrasound. Baseline ultrasound showed hydronephrosis with or without ureteral dilatation with echogenic content occupying the renal calyx (6), pelvis (10) or ureter (12). After injection of contrast, enhancement was noticed in 100% of the lesions, with similar intensity to the cortex in 23, and less in 5. Twenty-four lesions showed early washout, before the cortex, between 40 and 55seconds after the injection. The diagnosis was correct in 27 cases. Localisation coincided with the histological specimen in 28 cases, and 3 patients had additional distal carcinoma foci. CONCLUSION: Contrast-enhanced ultrasound is a useful technique for diagnosing upper tract urothelial tumours that increases confidence in the diagnosis.

Interrrelación docente entre las facultades de medicina de Valladolid y Santiago de Compostela. Una perspectiva histórica / No disponible

En España las Facultades de Medicina periféricas fueron de creación más antigua que las ubicadas en las grandes capitales del Reino. El desarrollo histórico del país hizo que fuesen perdiendo importancia y fuesen utilizadas por los docentes como trampolín para acceder a la Facultad de Madrid, capital del Reino. Se analiza desde una perspectiva histórica la relación entre los profesores de la Facultad de Medicina de Valladolid y Santiago de Compostela y la utilización por estos para el acceso a la Facultad de Medicina de Madrid como meta docente nacional durante el siglo XIX y primera mitad del XX

In Spain the peripheral Medicine Schools were founded before those at the capital Kingdon but de historical development maked that were lose importance and were used like promotion for going to the Madrid School of Medicine. This paper develops a historical perspective about the Medicine School of Valladolid and Santiago de Compostela for making easy the access to Madrid School during the XIX and XX century

Retinal vascular changes in preterm infants: heart and lung diseases and plus disease.

PURPOSE: To report the retinal vascular features of preterm infants with congenital heart disease (CHD), lung disease (pulmonary hypertension [PH] and bronchopulmonary dysplasia [BPD]), and ROP with plus disease to determine whether these disease entities are distinguishable on the basis of retinal vessel morphology. METHODS: The medical records of preterm infants with CHD, lung disease, and ROP with plus disease were reviewed retrospectively. Qualitative vascular findings were validated using computer-based software to analyze 25 representative images, each corresponding to one infant's eye. The images were organized into five groups, based on clinical information. Vessel diameter (d) and tortuosity index (TI) were measured. RESULTS: A total of 106 infants (mean gestational age, 30.5 ± 2.22 weeks) were initially included. Ophthalmologic evaluation of preterm infants with CHD and lung diseases showed vascular tortuosity without vasodilation at the posterior pole as well as in the periphery. Quantitative analysis showed that venular diameter was significantly increased in the plus disease group (P = 0.0022) compared to other groups. There was significantly less tortuosity in both arterioles and venules in BPD (P < 0.001, P = 0.0453) compared with plus group. CONCLUSIONS: The patterns of retinal vascular tortuosity observed in preterm infants may be unique to different systemic congestive conditions and could have therapeutic implications.

Evaluation of bacterial adherence of clinical isolates of Staphylococcus sp. using a competitive model: An in vitro approach to the "race for the surface" theory.

OBJECTIVES: Implant-related infection is one of the most devastating complications in orthopaedic surgery. Many surface and/or material modifications have been developed in order to minimise this problem; however, most of the in vitro studies did not evaluate bacterial adhesion in the presence of eukaryotic cells, as stated by the 'race for the surface' theory. Moreover, the adherence of numerous clinical strains with different initial concentrations has not been studied. METHODS: We describe a method for the study of bacterial adherence in the presence of preosteoblastic cells. For this purpose we mixed different concentrations of bacterial cells from collection and clinical strains of staphylococci isolated from implant-related infections with preosteoblastic cells, and analysed the minimal concentration of bacteria able to colonise the surface of the material with image analysis. RESULTS: Our results show that clinical strains adhere to the material surface at lower concentrations than collection strains. A destructive effect of bacteria on preosteoblastic cells was also detected, especially with higher concentrations of bacteria. CONCLUSIONS: The method described herein can be used to evaluate the effect of surface modifications on bacterial adherence more accurately than conventional monoculture studies. Clinical strains behave differently than collection strains with respect to bacterial adherence.Cite this article: M. Martinez-Perez, C. Perez-Jorge, D. Lozano, S. Portal-Nuñez, R. Perez-Tanoira, A.

Protocolo SANTIAGO. Planificación reparación endovascular de aorta (EVAR) en situaciones de urgencia / SANTIAGO protocol. Endovascular aortic repair planning in emergency situations

INTRODUCCIÓN: La reparación endovascular de los aneurismas de la aorta abdominal (EVAR) con éxito precisa la previa realización de una medición anatómica precisa basada en el estudio angio-TC aórtica. En situaciones de urgencia el tiempo para medición y planificación del caso es limitado y la disponibilidad del estudio en formato DICOM no siempre es posible. OBJETIVO: Presentar un protocolo de planificación desarrollado en nuestro centro que permite reducir el tiempo necesario para realizar las medidas en terapia EVAR de aneurismas de aorta abdominal (AAA) rotos en situaciones de urgencia y describir los resultados de nuestro centro antes y después de la aplicación de este protocolo. MÉTODO: Presentamos un análisis descriptivo de morbimortalidad a 30 días y a un año basado en un registro prospectivo de todos los casos de rotura de AAA admitidos de modo consecutivo (n = 32) en el servicio de urgencias de un hospital nacional de referencia durante el periodo enero del 2013 a mayo del 2015 (28 meses). El protocolo SANTIAGO es un acrónimo que describe (en lengua inglesa) 8 pasos que deben ser siempre tenidos en cuenta para una planificación EVAR: S (Size the aneurysms), A (Access), N (Neck), T (bifurcaTion), I (Iliacs), A (Angulations), G (LenGth-LonGitud) y O (OK for material). En nuestro centro, la terapia EVAR en rotura aórtica se realiza bajo anestesia local y de modo percutáneo si la situación clínica del paciente lo permite. RESULTADOS: Tras la aplicación del protocolo SANTIAGO en nuestro centro, desde junio del 2014, se consiguió reducir la mortalidad en el tratamiento urgente de aneurismas aórticos infrarrenales rotos. Fueron desestimados para ningún tipo de intervención por su elevada morbimortalidad 3 pacientes de los 32 (9,3%) admitidos en urgencias. La mortalidad total a 30 días en pacientes tratados disminuyó del 46,6% (7/15) preprotocolo frente al 35,7%(5/14) posprotocolo y en pacientes intervenidos mediante técnica endovascular pasó del 25% (1/4) preprotocolo frente a un 0%(0/6) de mortalidad posprotocolo. El 66,6% (4/6) de los pacientes tratados mediante EVAR tras el implante del protocolo fueron intervenidos de modo percutáneo y bajo anestesia local. La mortalidad al año, registrada en mayo del 2016, fue en el grupo EVAR del 10% (1/10), tasa de reintervención al año del 7,1% (1/9) por endofuga tipo ib, resuelta con éxito. En el grupo de cirugía abierta la morbimortalidad a 12 meses fue del 63,15% (12/19) de los pacientes intervenidos, con registro de un fallecimiento por IAM 7 meses postintervención y sin datos de reintervenciones mayores al año. CONCLUSIONES: Basados en la mejora de resultados observada en nuestro centro, consideramos que la existencia de un protocolo de planificación EVAR permite una planificación esquemática y reproducible que optimiza el tiempo necesario para afrontar una situación de urgencia crítica y propicia el éxito de la reparación. Asimismo, existe la tendencia progresiva en nuestro centro a considerar el tratamiento EVAR como primera opción terapéutica para pacientes con AAA-r. La posibilidad de realizar esta técnica con anestesia local y abordaje percutáneo podría ser considerada como un factor independiente que condiciona la menor morbimortalidad global del procedimiento

INTRODUCTION: Successful endovascular treatment of ruptured abdominal aortic aneurysms (R-EVAR) requires a detailed planning of the procedure, as planning is the key step. Nevertheless, in cases of emergency the limited time for planning and the non-availability of good quality scan images (DICOM format) are common issues that determine the final result. OBJECTIVE: The aim of this paper is to present the results of r-AAA survival before and after a fast protocol was implemented in our centre for measuring and sizing r-EVAR in emergency situations. METHOD: Morbidity and mortality at 30 days and 1 year was prospectively recorded in all consecutive cases of r-AAA admitted to the emergency department of our hospital (n = 32) from January 2013 to May 2015 (28 months). The «SANTIAGO planning & sizing protocol» was implemented in June 2014. It is a fast method to remember key steps in planning EVAR. With the word SANTIAGO being a mnemonic device in which 8 basic and mandatory steps in planning can be summarised: S: Size, A: Access N: Neck, T: Bifurcation I: Iliacs, A: Angulations, G: Length, O: Ok for material. R-EVAR is performed in this centre under local anaesthesia and using a percutaneous approach, if the patient tolerates it, since June 2014. RESULTS: After implementation of the SANTIAGO protocol in June 2014, the 30 day mortality was reduced from 46.6% (7/15) to 35.7% (5/14) in all patients treated in our centre for a ruptured AAA. The mortality recorded in the endovascular group was 25% (1/4) pre-protocol and 0% (0/6) after in the period analysed. A percutaneous approach and local anaesthesia was used in 66% (4/6) patients in the EVAR Group after the protocol was implemented. The 1 year mortality was 10% for all patients treated in the R-EVAR group, with a secondary intervention rate of 7.1% (1/9) due to a type Ib endoleak. In the open repair group, the 1 year morbidity/mortality was 63.15% (12/19), with a patient death at 7 months due to a myocardial infarction. CONCLUSIONS: Our first results suggest that a fast protocol for planning and sizing in emergency situations seems to be associated with a lower 30 day mortality. A higher trend for considering the patient candidate for r-EVAR has been observed in our centre. Local anaesthesia and percutaneous approach have a probable influence on the lower morbidity and mortality of the endovascular cases

Exantema mucocutáneo inducido por Mycoplasma pneumoniae: ¿un nuevo síndrome separado del eritema multiforme? Un nuevo caso y revisión de la literatura / Mycoplasma pneumoniae-Induced Mucocutaneous Rash: A New Syndrome Distinct from Erythema Multiforme? Report of a New Case and Review of the Literature

La infección respiratoria por Mycoplasma pneumoniae (MP) puede producir erupciones cutáneo-mucosas que se han considerado parte del espectro eritema multiforme o del síndrome de Stevens-Johnson. La clasificación de estas reacciones cutáneas, que tiene importancia pronóstica y terapéutica, ha generado mucha controversia en la literatura. Recientemente, una revisión sistemática de 202 casos de erupciones mucocutáneas asociadas a infección por MP concluye que pueden constituir una entidad distinta para la que se propone la expresión Mycoplasma-induced rash and mucositis. Presentamos un caso de infección respiratoria aguda por MP con lesiones mucosas y cutáneas difíciles de clasificar como eritema multiforme o síndrome de Stevens-Johnson, y cuyas características son compatibles con la nueva enfermedad propuesta

Respiratory tract infection due to Mycoplasma pneumoniae can provoke cutaneous and mucosal rashes, which have been classified within the spectrum of erythema multiforme or Stevens-Johnson syndrome.
