An investigation into CLIL-related sections of EFL coursebooks : issues of CLIL inclusion in the publishing market
The current ELT global coursebook market has embraced CLIL as a weak form of bilingual education and an innovative component to include in General English coursebooks for EFL contexts. In this paper I investigate how CLIL is included in ELT coursebooks aimed at
teenaged learners, available to teachers in Argentina. My study is based on the content analysis of four series which include a section advertised as CLIL-oriented. Results suggest that such sections are characterised by (1) little correlation between featured subject specific content and school curricula in L1, (2) oversimplification of contents, and (3) dominance of reading skills development and lower-order thinking tasks. Through this study, I argue that
CLIL components become superficial supplements rather than a meaningful attempt to promote weak forms of bilingual education
An international comparative study of blood pressure in populations of European vs. African descent
Background: The consistent finding of higher prevalence of hypertension in US blacks compared
to whites has led to speculation that African-origin populations are particularly susceptible to this
condition. Large surveys now provide new information on this issue.
Methods: Using a standardized analysis strategy we examined prevalence estimates for 8 white
and 3 black populations (N = 85,000 participants).
Results: The range in hypertension prevalence was from 27 to 55% for whites and 14 to 44% for
blacks.
Conclusions: These data demonstrate that not only is there a wide variation in hypertension
prevalence among both racial groups, the rates among blacks are not unusually high when viewed
internationally. These data suggest that the impact of environmental factors among both
populations may have been under-appreciated
Surgical management of enchondroma with joint transfer: a case report
The enchondromas are the most common benign bone tumor in the hands, mainly in young patients and its treatment is surgical in most cases due to its possible complications avoided through different procedures such as joint transfer, which allows to maintain a good quality of life for the patient. We present the case of a 42-year-old woman who came to the clinic for blunt trauma in the right hand where she was incidentally diagnosed with enchondroma on the third finger of the proximal interphalangeal joint of the right hand. Articular transfer of the proximal interphalangeal joint was performed. Second toe on the right, at 6 weeks corroborates correct evolution with bone consolidation of the articular transfer grade III and donor zone grade II, without infection complications, the correct recovery of the extensor movement range of this joint improving so their state of life should be the main objective of these procedures
Mediterranean lifestyle index and 24-h systolic blood pressure and heart rate in community-dwelling older adults
Specifc foods, nutrients, dietary patterns, and physical activity are associated with lower
blood pressure (BP) and heart rate (HR), but little is
known about the joint efect of lifestyle factors captured in a multidimensional score. We assessed the
association of a validated Mediterranean-lifestyle
(MEDLIFE) index with 24-h-ambulatory BP and
HR in everyday life among community-living older
adults. Data were taken from 2,184 individuals (51%
females, mean age: 71.4 years) from the SeniorsENRICA-2 cohort. The MEDLIFE index consisted
of 29 items arranged in three blocks: 1) Food consumption; 2) Dietary habits; and 3) Physical activity, rest, and conviviality. A higher MEDLIFE score (0–29 points) represented a better Mediterranean
lifestyle adherence. 24-h-ambulatory BP and HR
were obtained with validated oscillometric devices.
Analyses were performed with linear regression
adjusted for the main confounders. The MEDLIFEhighest quintile (vs Q1) was associated with lower
nighttime systolic BP (SBP) (-3.17 mmHg [95% CI:
-5.25, -1.08]; p-trend=0.011), greater nocturnal-SBP
fall (1.67% [0.51, 2.83]; p-trend=0.052), and lower
HR (-2.04 bpm [daytime], -2.33 bpm [nighttime], and
-1.93 bpm [24-h]; all p-trend<0.001). Results were
similar for each of the three blocks of MEDLIFE and
by hypertension status (yes/no). Among older adults,
higher adherence to MEDLIFE was associated with
lower nighttime SBP, greater nocturnal-SBP fall,
and lower HR in their everyday life. These results
suggest a synergistic BP-related protection from the components of the Mediterranean lifestyle. Future
studies should determine whether these results replicate in older adults from other Mediterranean and
non-Mediterranean countriesThis work was

The burden of blood-pressure-related cardiovascular mortality in Mexico
This study shows that in Mexico, a country at an advanced stage in the epidemiologic transition, with the national burden of disease dominated by noncommunicable diseases, elevated blood pressure is a major clinical and public health problem. 31.7% of the Mexican individuals aged 50 and over had systolic hypertension, and 47.3% were at systolic prehypertensive levels. Also, approximately
half of all cardiovascular deaths that occurred annually in the population of Mexico aged ≥50 years are attributable to above optimal levels of systolic blood pressure. We think these estimates may help order health priorities in Mexico (and other middle-income countries) at a time when the costs of medical care take a considerable share of the gross national product in most countries
Methodologies used to estimate tobacco-attributable mortality: a review
<p>Abstract</p> <p>Background</p> <p>One of the most important measures for ascertaining the impact of tobacco on a population is the estimation of the mortality attributable to its use. To measure this, a number of indirect methods of quantification are available, yet there is no consensus as to which furnishes the best information. This study sought to provide a critical overview of the different methods of attribution of mortality due to tobacco consumption.</p> <p>Method</p> <p>A search was made in the Medline database until March 2005 in order to obtain papers that addressed the methodology employed for attributing mortality to tobacco use.</p> <p>Results</p> <p>Of the total of 7 methods obtained, the most widely used were the prevalence methods, followed by the approach proposed by Peto et al, with the remainder being used in a minority of studies.</p> <p>Conclusion</p> <p>Different methodologies are used to estimate tobacco attributable mortality, but their methodological foundations are quite similar in all. Mainly, they are based on the calculation of proportional attributable fractions. All methods show limitations of one type or another, sometimes common to all methods and sometimes specific.</p
VKORC1 gene polymorphism as cardiovascular biomarker: Detection by electrochemical genosensors
Warfarin is an anticoagulant generally used to prevent cardiovascular diseases. Since of the low therapeutic index of warfarin and frequent complications of prevention or treatment, significant differences in individual doses of warfarin are needed to achieve prophylactic and therapeutic ranges. Recent studies have been reporting that genetic variants of vitamin K epoxide reductase complex (VKORC1) influence the response to warfarin and doses [9]. So, the genetic and pharmacogenetic information of the major cardiovascular diseases plays an important role in the identification of the cardiovascular risk factors and in the diagnosis and treatment of these conditions. This work addresses the development of a disposable electrochemical genosensor able of detecting single nucleotide polymorphism (SNP) in the VKORC1 gene. Analysing public databases, two specific 52 bp DNA probes, one with adenine (TA) and another with guanine (TG) SNP genetic variation were selected and selected and designed. The genosensor methodology implied the immobilization of a mixed self-assembled monolayer (SAM) linear VKORC1 DNA-capture probe and mercaptohexanol (MCH) onto screen-printed gold electrodes (SPGE). To improve the genosensor´s selectivity and avoid strong secondary structures, that could hinder the hybridization efficiency, a sandwich format of the VKORC1 allele was designed using a complementary fluorescein isothiocyanate-labelled signaling DNA probe and enzymatic amplification of the electrochemical signal. Preliminary studies indicate that differences in the electrochemical answers were obtained depending of the hybridization reaction format. In fact, higher electrochemical intensities were measured when the hybridization reaction was performed with a complementary DNA (without SNPs). These results suggested that the sensor is able to discriminate between the complementary DNA and single base mismatch targets having a great potential for the DNA polymorphism analysis.info:eu-repo/semantics/publishedVersio
Development of electrochemical genosensors for the CYPC*2 gene polymorphism detection
Pharmacogenetic studies search for heritable genetic polymorphisms that influence responses to drug therapy. Pharmacogenetics has many possible applications in cardiovascular pharmacotherapy including screening for polymorphisms to choose agents with the greatest potential for efficacy and least risk of toxicity. Pharmacogenetics also informs dose adaptations for specific drugs in patients with aberrant metabolism. Cardiovascular diseases (CVD) are considered one of the leading causes of death worldwide. To prevent cardiovascular complications and further loss of life oral anticoagulants (e.g., warfarin) are frequently prescribed to patients. Nevertheless, warfarin therapeutic agent presents narrow therapeutic windows with well-documented health risks. Some of these dose-responses are a result of specific single-nucleotide polymorphism (SNP) genetic variations present in a patient´s DNA. Among them, determined SNP in the cytochrome P4502C9 (CYP2C9), namely the CYP2C9*2, gene has been identified as dose-response altering SNP. Therefore, the need for a rapid, selective, low-cost and in real time detection device is crucial before prescribing any anticoagulant. In this work an analytical approach based on electrochemical genosensor technique is under development to create a low-cost genotyping platform able to genotype SNPs related with the therapeutic response of warfarin. Analyzing public databases, two specific 71 bp DNA probes, one with adenine (TA) and other with guanine (TG) SNP genetic variation were selected and designed. The design of this electrochemical genosensor consists of ssDNA immobilization onto gold surfaces that act as the SNPs complementary probes. The hybridization reaction is performed in a sandwich format of the complementary ssDNA, using an enzymatic scheme to amplify the electrochemical signal. The electrochemical signal was performed by using chronoamperometric technique.info:eu-repo/semantics/publishedVersio
Low Rates of Both Lipid-Lowering Therapy Use and Achievement of Low-Density Lipoprotein Cholesterol Targets in Individuals at High-Risk for Cardiovascular Disease across Europe
Aims
To analyse the treatment and control of dyslipidaemia in patients at high and very high cardiovascular
risk being treated for the primary prevention of cardiovascular disease (CVD) in
Europe.
Methods and Results
Data were assessed from the European Study on Cardiovascular Risk Prevention and Management
in Usual Daily Practice (EURIKA, ClinicalTrials.gov identifier: NCT00882336),
which included a randomly sampled population of primary CVD prevention patients from 12
European countries (n = 7641). Patients’ 10-year risk of CVD-related mortality was calculated
using the Systematic Coronary Risk Evaluation (SCORE) algorithm, identifying 5019
patients at high cardiovascular risk (SCORE 5% and/or receiving lipid-lowering therapy),
and 2970 patients at very high cardiovascular risk (SCORE 10% or with diabetes
mellitus). Among high-risk individuals, 65.3% were receiving lipid-lowering therapy, and
61.3% of treated patients had uncontrolled low-density lipoprotein cholesterol (LDL-C)
levels ( 2.5 mmol/L). For very-high-risk patients (uncontrolled LDL-C levels defined as
1.8 mmol/L) these figures were 49.5% and 82.9%, respectively. Excess 10-year risk of
CVD-related mortality (according to SCORE) attributable to lack of control of dyslipidaemia
was estimated to be 0.72%and 1.61% among high-risk and very-high-risk patients, respectively.
Among high-risk individuals with uncontrolled LDL-C levels, only 8.7% were receiving
a high-intensity statin (atorvastatin 40 mg/day or rosuvastatin 20 mg/day). Among veryhigh-
risk patients, this figure was 8.4%.
Conclusions
There is a considerable opportunity for improvement in rates of lipid-lowering therapy use
and achievement of lipid-level targets in high-risk and very-high-risk patients being treated
for primary CVD prevention in EuropeWriting support was provided by Oxford

Cost of poor adherence to anti-hypertensive therapy in five European countries
The financial burden for EU health systems associated with cardiovascular disease (CV) has been estimated to be nearly €110 billion in 2006, corresponding to 10 % of total healthcare expenditure across EU or a mean €223 annual cost per capita. The main purpose of this study is to estimate the costs related to hypertension and the economic impact of increasing adherence to anti-hypertensive therapy in five European countries (Italy, Germany, France, Spain and England). A probabilistic prevalence-based decision tree model was developed to estimate the direct costs of CV related to hypertension (CV defined as: stroke, heart attack, heart failure) in five European countries. Our model considered adherence to hypertension treatment as a main driver of blood pressure (BP) control (BP < 140/90 mmHg). Relative risk of CV, based on controlled or uncontrolled BP group, was estimated from the Framingham Heart Study and national review data. Prevalence and cost data were estimated from national literature reviews. A national payer (NP) perspective for 10 years was considered. Probabilistic sensitivity analysis was performed in order to evaluate uncertainty around the results (given as 95 % confidence intervals). The model estimated a total of 8.6 million (1.4 in Italy, 3.3 in Germany, 1.2 in Spain, 1.8 in France and 0.9 in England) CV events related to hypertension over the 10-year time horizon. Increasing the adherence rate to anti-hypertensive therapy to 70 % (baseline value is different for each country) would lead to 82,235 fewer CV events (24,058 in Italy, 7,870 in Germany, 18,870 in Spain, 24,855 in France and 6,553 in England). From the NP perspective, the direct cost associated with hypertension was estimated to be €51.3 billion (8.1 in Italy, 17.1 in Germany, 12.2 in Spain, 8.8 in France and 5.0 in England). Increasing adherence to anti-hypertensive therapy to 70 % would save a total of €332 million (CI 95 %: €319-346 million) from the NPs perspective. This study is the first attempt to estimate the economic impact of non-adherence amongst patients with diagnosed hypertension in Europe, using data from five European countries (Italy, France, Germany, Spain and England). © 2014 Springer-Verlag Berlin Heidelberg
