Perceptions and attitudes of clinicians in Spain toward clinical practice guidelines and grading systems: a protocol for a qualitative study and a national survey
BACKGROUND:
Clinical practice guidelines (CPGs) have become a very popular tool for decision making in healthcare. While there is some evidence that CPGs improve outcomes, there are numerous factors that influence their acceptability and use by healthcare providers. While evidence of clinicians' knowledge, perceptions and attitudes toward CPGs is extensive, results are still disperse and not conclusive. Our study will evaluate these issues in a large and representative sample of clinicians in Spain.
METHODS/DESIGN:
A mixed-method design combining qualitative and quantitative research techniques will evaluate general practitioners (GPs) and hospital-based specialists in Spain with the objective of exploring attitudes and perceptions about CPGs and evidence grading systems. The project will consist of two phases: during the first phase, group discussions will be carried out to gain insight into perceptions and attitudes of the participants, and during the second phase, this information will be completed by means of a survey, reaching a greater number of clinicians. We will explore these issues in GPs and hospital-based practitioners, with or without previous experience in guideline development.
DISCUSSION:
Our study will identify and gain insight into the perceived problems and barriers of Spanish practitioners in relation to guideline knowledge and use. The study will also explore beliefs and attitudes of clinicians towards CPGs and evidence grading systems used to rate the quality of the evidence and the strength of recommendations. Our results will provide guidance to healthcare researchers and healthcare decision makers to improve the use of guidelines in Spain and elsewhere

Association between dietary fibre intake and fruit, vegetable or whole-grain consumption and the risk of CVD: results from the PREvención con DIeta MEDiterránea (PREDIMED) trial
Prospective studies assessing the association between fibre intake or fibre-rich food consumption and the risk of CVD have often been limited
by baseline assessment of diet. Thus far, no study has used yearly repeated measurements of dietary changes during follow-up. Moreover,
previous studies included healthy and selected participants who did not represent subjects at high cardiovascular risk. We used yearly
repeated measurements of diet to investigate the association between fibre intake and CVD in a Mediterranean cohort of elderly adults at
high cardiovascular risk. We followed-up 7216 men (55–80 years) and women (60–80 years) initially free of CVD for up to 7 years in the
PREvención con DIeta MEDiterránea study (registered as ISRCTN35739639). A 137-item validated FFQ was repeated yearly to assess diet. The
primary end point, confirmed by a blinded ad hoc Event Adjudication Committee, was a composite of cardiovascular death, myocardial
infarction and stroke. Time-dependent Cox’s regression models were used to estimate the risk of CVD according to baseline dietary exposures
and to their yearly updated changes. We found a significant inverse association for fibre (Pfor trend =0·020) and fruits (Pfor trend=0·024) in
age-sex adjusted models, but the statistical significance was lost in fully adjusted models. However, we found a significant inverse association
with CVD incidence for the sum of fruit and vegetable consumption. Participants who consumed in total nine or more servings/d of fruits
plus vegetables had a hazard ratio 0·60 (95% CI 0·40, 0·96) of CVD in comparison with those consuming <5 servings/d
Mediterranean Diet Decreases the Initiation of Use of Vitamin K Epoxide Reductase Inhibitors and Their Associated Cardiovascular Risk: A Randomized Controlled Trial
Our aim is to assess whether following a Mediterranean Diet (MedDiet) decreases
the risk of initiating antithrombotic therapies and the cardiovascular risk associated with its
use in older individuals at high cardiovascular risk. We evaluate whether participants of
the PREvención con DIeta MEDiterránea (PREDIMED) study allocated to a MedDiet enriched
in extra-virgin olive oil or nuts (versus a low-fat control intervention) disclose differences in
the risk of initiation of: (1) vitamin K epoxide reductase inhibitors (acenocumarol/warfarin;
n = 6772); (2) acetylsalicylic acid as antiplatelet agent (n = 5662); and (3) other antiplatelet drugs
(cilostazol/clopidogrel/dipyridamole/ditazol/ticlopidine/triflusal; n = 6768). We also assess whether
MedDiet modifies the association between the antithrombotic drug baseline use and incident
cardiovascular events. The MedDiet intervention enriched with extra-virgin olive oil decreased
the risk of initiating the use of vitamin K epoxide reductase inhibitors relative to control diet
(HR: 0.68 [0.46–0.998]). Their use was also more strongly associated with an increased risk
of cardiovascular disease in participants not allocated to MedDiet interventions (HRcontrol diet:
4.22 [1.92–9.30], HRMedDiets: 1.71 [0.83–3.52], p-interaction = 0.052). In conclusion, in an older
population at high cardiovascular risk, following a MedDiet decreases the initiation of antithrombotic
therapies and the risk of suffering major cardiovascular events among users of vitamin K epoxide
reductase inhibitors

GWAS for systemic sclerosis identifies multiple risk loci and highlights fibrotic and vasculopathy pathways
Systemic sclerosis (SSc) is an autoimmune disease that shows one of the highest mortality rates among rheumatic diseases. We perform a large genome-wide association study (GWAS), and meta-analysis with previous GWASs, in 26,679 individuals and identify 27 independent genome-wide associated signals, including 13 new risk loci. The novel associations nearly double the number of genome-wide hits reported for SSc thus far. We define 95% credible sets of less than 5 likely causal variants in 12 loci. Additionally, we identify specific SSc subtype-associated signals. Functional analysis of high-priority variants shows the potential function of SSc signals, with the identification of 43 robust target genes through HiChIP. Our results point towards molecular pathways potentially involved in vasculopathy and fibrosis, two main hallmarks in SSc, and highlight the spectrum of critical cell types for the disease. This work supports a better understanding of the genetic basis of SSc and provides directions for future functional experiments
