The OTC derivatives markets after financial reforms. CEPS ECMI Commentary No. 36, May 2014

Over the past five years, over-the-counter (OTC) derivatives markets have received heightened regulatory attention, due to their opaqueness, size and interconnectedness, with a view to improving the robustness, safety and resilience of this market segment. There has been continued progress in the follow-up to the G-20 commitments, with the EU (EMIR, MIFID II, CRD/CRR IV, MAD) and the US (Swap Execution Facility or SEF, Title VII of Dodd-Frank Act, Basel III) leading in the implementation timelines and capturing approximately 80-90% of the overall market. Based on the data compiled for the yearly ECMI Statistical Package, this commentary provides a snapshot of the current status of the global OTC derivatives markets by: i) identifying general trends over the past decade, ii) looking at the changes in the market structure (instruments and participants), iii) estimating the uncollateralised derivatives exposure and iv) examining the relationship between OTC derivatives and exchange-traded derivatives (ETD).

Tissue transglutaminase and the progression of human renal scarring

ABSTRACT. Experimental renal scarring indicates that tissue transglutaminase (tTg) may be associated with the accumulation of extracellular matrix (ECM), both indirectly via TGF-β1 activation and directly by the formation of ε(γ-glutamyl) lysine dipeptide bonds within the ECM. The latter potentially accelerates deposition and confers the ECM with resistance to proteolytic digestion. Studied were 136 human renal biopsy samples from a range of chronic renal diseases (CRD) to determine changes in tTg and ε(γ-glutamyl) lysine crosslinking. Immunofluorescence for insoluble tTg showed a 14-fold increase in the kidneys of CRD patients (5.3 ± 0.5 versus 76 ± 54 mV/cm2), which was shown to be active by a similar 11-fold increase in the ε(γ-glutamyl) lysine crosslink (1.8 ± 0.2 versus 19.3 ± 14.2 mV/cm2). Correlations were obtained with renal function for tTg and crosslink. In situ hybridization for tTg mRNA showed that tubular epithelial cells were the major source of tTg; however, both mesangial and interstitial cells also contributed to elevated levels in CRD. This mRNA pattern was consistent with immunohistochemistry for soluble tTg. Changes in renal tTg and its product, the ε(γ-glutamyl) lysine crosslink, occur in progressive renal scarring in humans independently of the original etiology and in a similar manner to experimental models. tTg may therefore play a role in the pathogenesis of renal scarring and fibrosis in patients with CRD and can therefore be considered a potential therapeutic target.

Measurement of fusional vergence: protocol for a systematic review

Introduction - No validated protocol exists for the measurement of the prism fusion ranges. Many studies report on how fusional vergence ranges can be measured using different techniques (rotary prism, prism bar, loose prisms and synoptophore) and stimuli, leading to different ranges being reported in the literature. Repeatability of the different methods available and the equivalence between them it is also important. In addition, some studies available do not agree in what order fusional vergence should be measured to provide the essential information on which to base clinical judgements on compensation of deviations. When performing fusional vergence testing the most commonly accepted clinical technique is to first measure negative fusional vergence followed by a measurement of positive fusional vergence to avoid affecting the value of vergence recovery because of excessive stimulation of convergence. Von Noorden recommend using vertical fusion amplitudes in between horizontal amplitudes (base-out, base-up, base-in, and base down) to prevent vergence adaptation. Others place the base of the prism in the direction opposite to that used to measure the deviation to increase the vergence demand. Objectives - The purpose of this review is to assess and compare the accuracy of tests for measurement of fusional vergence. Secondary objectives are to investigate sources of heterogeneity of diagnostic accuracy including: age; variation in method of assessment; study design; study size; type of strabismus (convergent, divergent, vertical, cycle); severity of strabismus (constant/intermittent/latent).

Chronic respiratory diseases and quality of life in elderly nursing home residents

Few studies have assessed the quality of life (QOL) related to chronic respiratory diseases in the elderly. In the framework of the geriatric study on the health effects of air quality in elderly care centers (GERIA) study, a questionnaire was completed by elderly subjects from 53 selected nursing homes. It included various sections in order to assess respiratory complaints, QOL (World Health Organization QOL (WHOQOL)-BREF), and the cognitive and depression status. The outcome variables were the presence of a score lower than 50 (<50) in each of the WHOQOL-BREF domains (physical health, psychological health, social relationships, and environmental health). Chronic bronchitis, frequent cough, current wheezing, asthma, and allergic rhinitis were considered as potential risk factors. The surveyed sample was (n = 887) 79% female, with a mean age of 84 years (SD: 7 years). In the multivariable analysis, a score of <50 in the physical domain was associated with wheezing in the previous 12 months (odds ratio (OR): 2.03, confidence interval (CI): 1.25-3.31) and asthma (OR: 1.95, CI: 1.12-3.38). The psychological domain was related with a frequent cough (OR: 1.43, CI: 0.95-2.91). A score of <50 in the environmental domain was associated with chronic bronchitis (OR: 2.89, CI: 1.34-6.23) and emphysema (OR: 3.89, CI: 1.27-11.88). In view of these findings, the presence of respiratory diseases seems to be an important risk factor for a low QOL among elderly nursing home residents.

Regras de Prescrição de Cuidados Respiratórios Domiciliários

Um dos objetivos do Programa Nacional para as Doenças Respiratórias (PNDR) constitui a melhoria da qualidade de prescrição e utilização de Cuidados Respiratórios Domiciliários (CRD). No momento atual, em Portugal, a prescrição de CRD é efetuada ao abrigo das Normas de Orientação Clínica (NOC) da Direção-Geral da Saúde com o objetivo de procurar melhorar a qualidade da prática de prescrição de CRD, nomeadamente, através da definição de regras de boa prática na prescrição de CRD, por terapêutica respiratória domiciliária (Oxigenoterapia de Longa Duração, Aerossolterapia e Ventiloterapia) e por patologia (Síndrome de Apneia do Sono, Deformações do Tórax, Doenças Neuromusculares, Doença Pulmonar Obstrutiva Crónica e outras patologias que condicionem Insuficiência Respiratória Crónica) e da articulação das NOC com o concurso público para a celebração de contratos públicos de aprovisionamento para a área da saúde, com vista à prestação de serviços de cuidados técnicos respiratórios domiciliários aos utentes do SNS.

Modelo de gestión para la atención integral de pacientes con enfermedades huérfanas o raras en Colombia

Las enfermedades raras o huérfanas corresponden a aquellas con baja prevalencia en la población, y en varios países tienen una definición distinta de acuerdo con el número de pacientes que afectan en la población. La Organización Mundial de la Salud (OMS), las define como un trastorno que afecta de 650 a 1.000 personas por millón de habitantes, de las que se han identificado alrededor de 7.000. En Colombia su prevalencia es menor de 1 por cada 5.000 personas y comprenden: las enfermedades raras, las ultra-huérfanas y las olvidadas. Los pacientes con este tipo de enfermedades imponen retos a los sistemas sanitarios, pues si bien afectan a un bajo porcentaje de la población, su atención implica una alta carga económica por los costos que involucra su atención, la complejidad en su diagnóstico, tratamiento, seguimiento y rehabilitación. El abordaje de las enfermedades raras requiere un manejo interdisciplinar e intersectorial, lo que implica la organización de cada actor del sistema sanitario para su manejo a través de un modelo que abraque las dinámicas posibles entre ellos y las competencias de cada uno. Por lo anterior, y teniendo en cuenta la necesidad de formular políticas sanitarias específicas para la gestión de estas enfermedades, el presente trabajo presenta una aproximación a la formulación de un modelo de gestión para la atención integral de pacientes con enfermedades raras en Colombia. Esta investigación describe los distintos elementos y características de los modelos de gestión clínica y de las enfermedades raras a través de una revisión de literatura, en la que se incluye la descripción de los distintos actores del Sistema de Salud Colombiano, relacionados con la atención integral de estos pacientes para la documentación de un modelo de gestión integral.

Trabajo nocturno e índice de masa corporal en los trabajadores de la salud : una revisión de la literatura

Introducción: Se considera el trabajo rotativo nocturno como aquel que se lleva a cabo fuera de las horas laborales diurnas. Se ha planteado que el trabajo en horas nocturnas podría estar relacionado con diversos desordenes, dentro de ellos un incremento en el índice de masa corporal con el consecuente desarrollo de sobrepeso y obesidad. El objetivo de este estudio es realizar una revisión de la literatura existente, acerca del trabajo rotativo nocturno y su relación con el índice de masa corporal (IMC) en trabajadores de la salud. Métodos: Se realizó una revisión sistemática de información publicada en los últimos 10 años en la base de datos PUBMED y se seleccionaron únicamente los artículos de texto completo relacionados con este tema en los idiomas inglés, español e italiano. Resultados: A través de la búsqueda se encontraron 10 artículos que cumplieron los criterios de inclusión definidos. Predominantemente se obtuvieron estudios de diseño transversal. Tres de estos estudios encontraron una asociación entre trabajo rotativo nocturno actual e incremento en el IMC y por el contrario dos estudios no hallaron esta asociación. Por otro lado, seis estudios coinciden en una asociación positiva entre mayor tiempo acumulado en trabajo rotativo nocturno y un incremento en el IMC. Conclusiones: Los hallazgos encontrados en los estudios analizados apuntan a la existencia de una estrecha relación entre el aumento del Índice de Masa Corporal (IMC) con los turnos nocturnos (o rotativos que incluyen este horario) llevados a cabo de manera prolongada, en los trabajadores de la salud, en comparación con los trabajadores que realizan turnos diurnos regulares.

Veterinary allergy diagnosis: past, present and future perspectives

Fleas, several aeroallergens as well as many food allergens are the most common allergenic sources for animals and frequent cause of allergic reactions with different target organs such as skin, eyes, and respiratory or digestive systems. Allergy diagnosis needs to follow well-established guidelines under clinical and laboratory approaches. Since 1980 with the Hanifin & Rajka’s criteria for the diagnosis of atopic dermatitis (AD) in humans, successive proposals have been developed to identify atopic dermatitis in dogs. A consensual plan was first proposed by Willemse in 1986 undergoing several modifications in 1994. Prélaud and colleagues made important changes to the plan in 1998 and it was further adjusted by Favrot in 2009. In 2010, this plan was approved by the International Task Force on Canine Atopic Dermatitis (CAD). It was subjected in 2015 to minor updates with regard to therapeutic options. To improve diagnostic accuracy by integrating the basic knowledge on sensitization development and allergen nature and diversity, allergen sources and implicated molecular allergens for animals should be clearly identified. As well as in human medicine, this molecular epidemiology concept is essential for the veterinary allergy diagnosis in the near future, standing as the basis of a component-resolved diagnosis (CRD). Besides current pharma- cotherapy, it will be highly relevant to increase the efficiency of the avoidance measures and specific immunotherapy. Clinical guidelines will lead to at least 80 % of positive diagnosis of atopy, but newer laboratory methods in veterinary medicine aiming to a more precise diagnosis and a better integration of the clinical/laboratory diagnostic course are needed. Allergoms identification for animals, from different allergen sources proteoms should become a priority in veterinary allergology, in order to allow the intended CRD, which is essential to understand the cross-reaction phenomena, allowing a more precise and possibly effective component-resolved immunotherapy (CRIT). Further research has been carried out for a better understanding of the interaction between allergic clinical condition and immune pathophysiology. As well as in human medicine, a deeper knowledge of the molecular immunological mechanisms in veterinary allergy — with their specific allergen triggers — will also provide the veterinary allergist with the necessary information to act more efficiently in the future.

Nutritional technological characterization and secondary metabolites in stored carioca bean cultivars.

The recommendation of bean cultivars and the use of appropriate storage techniques allow the quality characteristics of these grains to be preserved for human consumption. The aim of this study was to characterize the effects of storage on three cultivars of the common carioca bean in raw form and to determine the relationships between storage time and technological quality parameters involved in the darkening and hardening of grains, the chemical composition of the beans and the presence of secondary metabolites. The experiment followed a completely randomized design (CRD) with a full factorial scheme consisting of two factors: bean cultivars, with three levels and storage time, with five levels. The color parameters and the storage times significantly differed between the cultivars. The cooking time, when compared to the water absorption index, indicated that the cultivars had, on average, a high percentage of moisture (>95%) and an average cooking time of 17 min., this applies to the control, while values increase during the storage time. Storage under ambient conditions led to a reduction in grain brightness parameters, characterized by darkening and hardening; no reduction in protein and mineral content; and an increase in iron, phosphorous, tannin, and phytic acid contents at 180 days.
