Screening premorbid metabolic syndrome in community pharmacies: a cross-sectional descriptive study

Background: Premorbid metabolic syndrome (pre-MetS) is a cluster of cardiometabolic risk factors characterised by central obesity, elevated fasting glucose, atherogenic dyslipidaemia and hypertension without established cardiovascular disease or diabetes. Community pharmacies are in an excellent position to develop screening programmes because of their direct contact with the population. The main aim of the study was to determine the prevalence of pre-MetS in people who visited community pharmacies for measurement of any of its five risk factors to detect the presence of other risk factors. The secondary aims were to study the presence of other cardiovascular risk factors and determine patients" cardiovascular risk. Methods: Cross-sectional, descriptive, multicentre study. Patients meeting selection criteria aged between 18 and 65 years who visited participating community pharmacies to check any of five pre-MetS diagnostic factors were included. The study involved 23 community pharmacies in Catalonia (Spain). Detection criteria for pre-MetS were based on the WHO proposal following IDF and AHA/NHBI consensus. Cardiovascular risk (CVR) was calculated by Regicor and Score methods. Other variables studied were smoking habit, physical activity, body mass index (BMI), and pharmacological treatment of dyslipidemia and hypertension. The data were collected and analysed with the SPSS programme. Comparisons of variables were carried out using the Student"s T-test, Chi-Squared test or ANOVA test. Level of significance was 5% (0.05). Results: The overall prevalence of pre-MetS was 21.9% [95% CI 18.7-25.2]. It was more prevalent in men, 25.5% [95% CI 22.1-28.9], than in women, 18.6% [95% CI 15.5-21.7], and distribution increased with age. The most common risk factors were high blood pressure and abdominal obesity. About 70% of people with pre-MetS were sedentary and over 85% had a BMI ≥25 Kg/m2 . Some 22.4% had two metabolic criteria and 27.2% of patients with pre-MetS had no previous diagnosis. Conclusions: The prevalence of pre-MetS in our study (21.9%) was similar to that found in other studies carried out in Primary Care in Spain. The results of this study confirm emergent cardiometabolic risk factors such as hypertension, obesity and physical inactivity. Our study highlights the strategic role of the community pharmacy in the detection of pre-MetS in the apparently healthy population.

Different effects of hyperlipidic diets in human lactation and adulthood: growth versus the development of obesity

After birth, the body shifts from glucose as primary energy substrate to milk-derived fats, with sugars from lactose taking a secondary place. At weaning, glucose recovers its primogeniture and dietary fat role decreases. In spite of human temporary adaptation to a high-fat (and sugars and protein) diet during lactation, the ability to thrive on this type of diet is lost irreversibly after weaning. We could not revert too the lactating period metabolic setting because of different proportions of brain/muscle metabolism in the total energy budget, lower thermogenesis needs and capabilities, and absence of significant growth in adults. A key reason for change was the limited availability of foods with high energy content at weaning and during the whole adult life of our ancestors, which physiological adaptations remain practically unchanged in our present-day bodies. Humans have evolved to survive with relatively poor diets interspersed by bouts of scarcity and abundance. Today diets in many societies are largely made up from choice foods, responding to our deeply ingrained desire for fats, protein, sugars, salt etc. Consequently our diets are not well adjusted to our physiological needs/adaptations but mainly to our tastes (another adaptation to periodic scarcity), and thus are rich in energy roughly comparable to milk. However, most adult humans cannot process the food ingested in excess because our cortical-derived craving overrides the mechanisms controlling appetite. This is produced not because we lack the biochemical mechanisms to use this energy, but because we are unprepared for excess, and wholly adapted to survive scarcity. The thrifty mechanisms compound the effects of excess nutrients and damage the control of energy metabolism, developing a pathologic state. As a consequence, an overflow of energy is generated and the disease of plenty develops.

Detección Precoz de los factores de riesgo cardiovasculares en los Centros de Atención Primaria de Cataluña Central

Las enfermedades cardiovasculares son actualmente la principal causa de muerte prematura, por lo que es necesario controlar los factores que podrían reducir el riesgo cardiovascular. El presente estudio se centra en la ejecución de los protocolos de prevención cardiovascular en los Centros de Atención Primaria de Cataluña central, ya que se cree que una prevención adecuada podría reducir significativamente la mortalidad por esta enfermedad. Para lograr este objetivo, se propone utilizar una muestra poblacional de 100 individuos entre 45 y 65 años y realizar un estudio cuantitativo descriptivo. Basándose éste, en el control de las diferentes variables que afectan en poseer factores de riesgo cardiovascular: el alcohol, el tabaco, la obesidad, la inactividad física, la diabetes y el colesterol.

The association between obesity and back pain in nine countries: a cross-sectional study

BACKGROUND: The association between obesity and back pain has mainly been studied in high-income settings with inconclusive results, and data from older populations and developing countries are scarce. The aim of this study was to assess this association in nine countries in Asia, Africa, Europe, and Latin America among older adults using nationally-representative data. METHODS: Data on 42116 individuals ≥50 years who participated in the Collaborative Research on Ageing in Europe (COURAGE) study conducted in Finland, Poland, and Spain in 2011-2012, and the World Health Organization's Study on Global Ageing and Adult Health (SAGE) conducted in China, Ghana, India, Mexico, Russia, and South Africa in 2007-2010 were analysed. Information on measured height and weight available in the two datasets was used to calculate Body Mass Index (BMI). Self-reported back pain occurring in the past 30 days was the outcome. Multivariable logistic regression analysis was used to assess the association between BMI and back pain. RESULTS: The prevalence of back pain ranged from 21.5% (China) to 57.5% (Poland). In the multivariable analysis, compared to BMI 18.5-24.9 kg/m(2), significantly higher odds for back pain were observed for BMI ≥35 kg/m(2) in Finland (OR 3.33), Russia (OR 2.20), Poland (OR 2.03), Spain (OR 1.56), and South Africa (OR 1.48); BMI 30.0-34.0 kg/m(2) in Russia (OR 2.76), South Africa (OR 1.51), and Poland (OR 1.47); and BMI 25.0-29.9 kg/m(2) in Russia (OR 1.51) and Poland (OR 1.40). No significant associations were found in the other countries. CONCLUSIONS: The strength of the association between obesity and back pain may vary by country. Future studies are needed to determine the factors contributing to differences in the associations observed.

The role of central bank operating procedures in an economy with productive government spending

The choice of either the rate of monetary growth or the nominal interest rate as the instrument controlled by monetary authorities has both positive and normative implications for economic performance. We reexamine some of the issues related to the choice of the monetary policy instrument in a dynamic general equilibrium model exhibiting endogenous growth in which a fraction of productive government spending is financed by means of issuing currency. When we evaluate the performance of the two monetary instruments attending to the fluctuations of endogenous variables, we find that the inflation rate is less volatile under nominal interest rate targeting. Concerning the fluctuations of consumption and of the growth rate, both monetary policy instruments lead to statistically equivalent volatilities. Finally, we show that none of these two targeting procedures displays unambiguously higher welfare levels.

Payments for environmental services in watersheds: insights from a comparative study of three cases in Central America

We have compared three cases of payments for water-related environmental services (PES) in Central America, in terms of socioeconomic background, opportunity costs of forest conservation and stakeholders’ perceptions on the conditions of water resources and other issues. We found that, in general, the foregone benefits from land uses alternative to forest cover are larger than the amount paid, which apparently contradicts the economic foundation of PES schemes. A number of possible explanations are explored. The results also suggest that trade-offs between different environmental and social goals are likely to emerge in PES schemes, posing some doubts on their ability to be multipurpose instruments for environmental improvement and rural development. We also found that PES schemes may work as a conflictresolution instrument, facilitating downstream -upstream problem solving, though at the same time they might introduce changes in social perceptions of property rights.

Ten Propositions on Rural Poverty and Agrarian Transition in Central Eurasia

The relation between agricultural development and rural poverty reduction in six Central Eurasian countries, namely Azerbaijan (South Caucasus) and Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan (Central Asia), is discussed by presenting and analyzing ten propositions. These propositions cover a broad range of issues that relate to rural poverty in this region, such as: the state of income and non-income poverty; the diverse processes of land reform and farm restructuring, and agricultural policy reform; and finally, the institutional and market framework that is needed for dynamic agricultural and rural development. The paper contends that rural poverty is not responding as robustly to rapid economic growth in these countries, and that agricultural growth, in particular in the newly emerging peasant farm sector, is necessary to promote rural poverty reduction.

When do central banks prefer to intervene secretly?

Central banks often intervene secretly in the foreign exchange market. This secrecy seems to be at odds with the signalling channel. In this article we will analyse when a central bank intervening in the foreign exchange rate market purely through the signalling channel would prefer to act secretly or publicly. By using a microstructure model, we will show that the consistency of the intervention with fundamentals, the volume of noise trading, the weight given to the effectiveness of intervention and the degree of superior information held by the central bank will influence the decision to intervene secretly or publicly. Keywords: foreign exchange intervention, market microstructure. JEL Classifi…cation: D82, E58, F31, G14.

Remeis casolans per a bèsties i humans: medicina i veterinària popular a la catalunya central

Treball de recerca realitzat per un alumne d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. Consisteix en un diccionari informàtic que recull plantes i productes, cadascun amb les seves propietats medicinals i altres usos que se’ls atribueixen popularment i la forma de preparar remeis i aplicar-los per a cada malaltia o afecció. La informació s’ha extret de les entrevistes fetes a informants d’entre 60 i 90 anys del Bages, Berguedà i Solsonès, i es complementa amb un herbari i una mostra de preparacions dels remeis.

Evolució del poblament i organització del territori a la Catalunya interior durant l'Antiguitat Tardana i l'Alta Edat Mitjana: els casos de la Catalunya Central (Bages, Berguedà i Solsonès) i la Garrotxa (segles V-X)

Projecte de recerca elaborat a partir d’una estada a la Université de Toulouse 2 – Le Mirail entre gener i juny del 2007. En concret, l’estada efectuada ha suposat la integració de qui signa aquesta memòria dins l’equip al-Andalus/Hispaniae, dirigit pel professor Philippe Sénac, una de les diverses branques que conformen el grup FRAMESPA d’aquella universitat, unitat de recerca adscrita al CNRS (UMR 5136). El títol proposat per al contingut de la recerca en la sol•licitud presentada, Evolució del poblament i organització del territori a la Catalunya interior a l’Alta Edat Mitjana, encapçalava un pla de treball que tenia per objectiu la recopilació i l’anàlisi de dades arqueològiques i textuals que oferissin un escenari a partir del qual establir una seqüència evolutiva en relació a les diferents tendències pel que fa al poblament tardoantic i altmedieval en dues zones diferenciades com són les conques mitjanes dels rius Llobregat i Cardener, a la Catalunya Central, i la capçalera del riu Fluvià, a la Garrotxa. Així, s’han pogut detectar, a partir de la contrastació de les diferents dades, fenòmens diversos que reflecteixen la incidència dels successius canvis històrics a nivell territorial i de poblament.

Estudi exploratori per a la reconstrucció de temperatures de l'aigua i de l'aire en la conca central del llac Baikal (Sibèria) en els últims 40000 anys

Aquest estudi consisteix en un anàlisi exploratori que té per objectiu principal la realització d’una reconstrucció de la temperatura de l’aigua i l’aire del llac Baikal durant els últims 40.000 anys. El treball s’ha dut a terme mitjançant l’ús de les proxys de reconstrucció de la temperatura y la utilització dels mètodes TEX86, MAAT, i la d’aportació de matèria orgànica d’origen terrestre, el BIT, aplicant-les a la mostra VER93-2 st GC-24, extreta pel Baikal Drilling Project a la conca central, amb l’objectiu de fer una aportació de dades paleoclimàtiques per tal d’aconseguir una millora en les interpretacions de futurs esdeveniments climàtics, i d’identificar esdeveniments climàtics sobtats, tals com els Heinrich events i els Youngers Dryas. Abans de la realització de l’anàlisi de les mostres s’ha dut a terme una extrapolació de l’edat en el testimoni, degut a que l’edat del core BDP VER93-2.st.GC-24 havia estat extrapolada fins a 277,5 cm de profunditat i en el present estudi s’ha ampliat l’anàlisi fins als 460 cm. de profunditat. Un cop obtinguts els resultats s’ha realitzat un càlcul de precisió i reproductibilitat per tal de conèixer una estimació quantitativa de la variabilitat de les dades obtingudes en les diferents proxys, en el qual ha estat demostrat una baixa variabilitat de les dades, exceptuant la variabilitat del TEX86 i la precisió del MAAT. Per a la localització dels diferents esdeveniments climàtics donats durant l’Holocè i el Plistocè s’han realitzat anàlisis gràfics dels propis resultats, juntament i en comparació dels resultats realitzats per Escala et al. (r.n.p [resultats no publicats]) en la conca sud, i de l’estudi publicat per Prokopenko et al., en el que s’analitza la presència de diatomees i matèria orgànica l’Atlàntic Nord. Els resultats integrats d’Escala et al.,(r.n.p) i els d’aquest estudi coincideixen en la datació dels diferents esdeveniments, amb alguna variació hipotèticament produïda per l’extrapolació d’edat realitzada en el present estudi i la gran aportació de matèria orgànica en el lloc d’extracció del testimoni per part del riu Selenga. Aquests resultats mostren una possible relació entre els esdeveniments climàtics i la variació de la temperatura de l’aigua.

Symmetric planar central configurations of five bodies: Euler plus two

We study planar central configurations of the five-body problem where three of the bodies are collinear, forming an Euler central configuration of the three-body problem, and the two other bodies together with the collinear configuration are in the same plane. The problem considered here assumes certain symmetries. From the three bodies in the collinear configuration, the two bodies at the extremities have equal masses and the third one is at the middle point between the two. The fourth and fifth bodies are placed in a symmetric way: either with respect to the line containing the three bodies, or with respect to the middle body in the collinear configuration, or with respect to the perpendicular bisector of the segment containing the three bodies. The possible stacked five-body central configurations satisfying these types of symmetries are: a rhombus with four masses at the vertices and a fifth mass in the center, and a trapezoid with four masses at the vertices and a fifth mass at the midpoint of one of the parallel sides.

Estudi d'adipoquines com a marcadors plasmàtics de síndrome metabòlica

La síndrome metabòlica s’associa amb un risc elevat de desenvolupar diabetis tipus 2 i malaltia cardiovascular. La síndrome metabòlica es defineix com un clúster d’anormalitats metabòliques i, d’entre totes, l’obesitat abdominal constitueix el factor de risc més prevalent i crític en el desenvolupament de la síndrome metabòlica, el risc cardiovascular augmentat i la resistència a la insulina. La prevalença augmentada de l’obesitat en la població a nivell mundial ha portat el teixit adipós al primer pla dels estudis epidemiològics. Anteriorment es considerava el reservori energètic de l’organisme, actualment es parla del teixit adipós com un òrgan endocrí, metabòlicament molt actiu, implicat en diferents vies i processos metabòlics. L’etiologia de l’obesitat és complexa i multifactorial, però es fa evident en la disfuncionalitat del teixit adipós. Un teixit adipós disfuncional veu superada la seva capacitat d’emmagatzemar lípid i respon amb la hipersecreció de diferents molècules (adipoquines, citoquines i mediadors inflamatoris) a favor de la resistència a la insulina, proinflamatòries i proaterogèniques. La fatty acid-binding protein 4 (FABP4) i la retinol-binding protein 4 (RBP4) són dues adipoquines que en circulació, es desconeix la funció exacta que duen a terme. Estudis recents han suggerit la FABP4 com a marcador d’adipositat, síndrome metabòlica i diabetis tipus 2. I, RBP4, malgrat que les dades de diferents estudis en humans desperten certa controvèrsia, s’ha associat amb la resistència a la insulina i el desenvolupament de la diabetis tipus 2. En aquesta memòria es recullen els treballs en què es va estudiar el paper d’aquestes adipoquines en relació a malalties de base metabòlica amb afectació del teixit adipós com són la síndrome metabòlica, la diabetis tipus 2, la hiperlipèmia familiar combinada i la, lipodistrofia associada a tractament combinat antiretroviral de la infecció pel virus de la immunodeficiència humana (VIH).
