Olive oil is well known for its cardioprotective properties; however, epidemiological data showing that olive oil consumption reduces incident CHD events are still limited. Therefore, we studied the ...association between olive oil and CHD in the European Prospective Investigation into Cancer and Nutrition (EPIC) Spanish cohort study. The analysis included 40 142 participants (38 % male), free of CHD events at baseline, recruited from five EPIC-Spain centres from 1992 to 1996 and followed up until 2004. Baseline dietary and lifestyle information was collected using interview-administered questionnaires. Cox proportional regression models were used to assess the relationship between validated incident CHD events and olive oil intake (energy-adjusted quartiles and each 10 g/d per 8368 kJ (2000 kcal) increment), while adjusting for potential confounders. During a 10·4-year follow-up, 587 (79 % male) CHD events were recorded. Olive oil intake was negatively associated with CHD risk after excluding dietary mis-reporters (hazard ratio (HR) 0·93; 95 % CI 0·87, 1·00 for each 10 g/d per 8368 kJ (2000 kcal) and HR 0·78; 95 % CI 0·59, 1·03 for upper v. lower quartile). The inverse association between olive oil intake (per 10 g/d per 8368 kJ (2000 kcal)) and CHD was more pronounced in never smokers (11 % reduced CHD risk (P = 0·048)), in never/low alcohol drinkers (25 % reduced CHD risk (P < 0·001)) and in virgin olive oil consumers (14 % reduced CHD risk (P = 0·072)). In conclusion, olive oil consumption was related to a reduced risk of incident CHD events. This emphasises the need to conserve the traditional culinary use of olive oil within the Mediterranean diet to reduce the CHD burden.
Fabry disease may be treated by enzyme replacement therapy (ERT), but the impact of chronic kidney disease (CKD) on the response to therapy remains unclear. The aim of the present study was to ...analyse the incidence and predictors of clinical events in patients on ERT.
Multicentre retrospective observational analysis of patients diagnosed and treated with ERT for Fabry disease. The primary outcome was the first renal, neurological or cardiological events or death during a follow-up of 60 months (24–120).
In 69 patients (42 males, 27 females, mean age 44.6±13.7 years), at the end of follow-up, eGFR and the left ventricular septum thickness remained stable and the urinary albumin: creatinine ratio tended to decrease, but this decrease only approached significance in patients on agalsidase-beta (242–128mg/g (p=0.05). At the end of follow-up, 21 (30%) patients had suffered an incident clinical event: 6 renal, 2 neurological and 13 cardiological (including 3 deaths). Events were more frequent in patients with baseline eGFR≤60ml/min/1.73m2 (log Rank 12.423, p=0.001), and this remained significant even after excluding incident renal events (log Rank 4.086, p=0.043) and in males and in females. Lower baseline eGFR was associated with a 3- to 7-fold increase the risk of clinical events in different Cox models.
GFR at the initiation of ERT is the main predictor of clinical events, both in males and in females, suggesting that start of ERT prior to the development of CKD is associated with better outcomes.
El objetivo de este estudio es realizar un mapa del tratamiento actual de la enfermedad de Fabry en España, analizando el efecto de diferentes factores en el desarrollo de eventos clínicos a largo plazo.
Análisis observacional retrospectivo multicéntrico. Criterios de inclusión: pacientes diagnosticados y tratados de enfermedad de Fabry. Se recogieron datos generales en relación con el diagnóstico, síntomas y tipo mutación, tipo de tratamiento recibido, evolución renal y cardiológica. Durante un tiempo de seguimiento de 60 meses (24-120), se recogió el primer evento clínico tras el inicio de tratamiento sustitutivo enzimático definido como mortalidad, evento renal, cardiológico o neurológico.
Se incluyeron 69 pacientes (42 H, 27 M) con una edad media de 44,6±13,7 años. A los cinco años de tratamiento, el FGe y la hipertrofia ventricular izquierda se mantuvieron estables, y la albuminuria tiende a disminuir, siendo este descenso más significativo en el grupo de pacientes tratados con beta-galactosidasa (de 242 a 128mg/g (p=0,05). Veintiún pacientes sufrieron un evento clínico (30%): seis renales, dos neurológicos y 13 cardiológicos (incluidas tres muertes). Los pacientes con ERC (FGe<60) antes del inicio de tratamiento tuvieron más eventos (log-rank 12.423, p=0,001), manteniéndose la predicción si excluíamos los eventos renales (log-rank 4.086 (p=0,043) en hombres y mujeres. La peor función renal al inicio del tratamiento aumentó entre tres y siete veces el riesgo de eventos clínicos en diferentes modelos de Cox ajustados.
La función renal al inicio de tratamiento sustitutivo enzimático es la principal predictora de desarrollo de eventos clínicos a largo plazo, tanto en hombres como mujeres. El inicio de tratamiento sustitutivo enzimático precoz antes del desarrollo de ERC mejoraría el pronóstico.
To prospectively assess the associations between lean fish, fatty fish and total fish intakes and risk of stroke in the Spanish cohort of the European Prospective Investigation into Cancer and ...Nutrition (EPIC-Spain). Fish intake was estimated from a validated dietary questionnaire. Cox proportional hazards regression models were used to assess the association between the intakes of lean fish, fatty fish and total fish and stroke risk. Models were run separately for men and women. Five Spanish regions (Asturias, San Sebastian, Navarra, Granada and Murcia). Individuals (n 41 020; 15 490 men and 25 530 women) aged 20-69 years, recruited from 1992 to 1996 and followed-up until December 2008 (December 2006 in the case of Asturias). Only participants with definite incident stroke were considered as cases. During a mean follow-up of 13.8 years, 674 strokes were identified and subsequently validated by record linkage with hospital discharge databases, primary-care records and regional mortality registries, comprising 531 ischaemic, seventy-nine haemorrhagic, forty-two subarachnoid and twenty-two unspecific strokes. After multiple adjustments, no significant associations were observed between lean fish, fatty fish and total fish consumption and the risk of stroke in men or women. In men, results revealed a non-significant trend towards an inverse association between lean fish (hazard ratio=0.84; 95 % CI 0.55, 1.29, P sub(trend)=0.06) and total fish consumption (hazard ratio=0.77; 95 % CI 0.51, 1.16, P sub(trend)=0.06) and risk of total stroke. In the EPIC-Spain cohort, no association was found between lean fish, fatty fish and total fish consumption and risk of stroke.
The evidence that individual dietary and lifestyle factors influence a person's weight and waist circumference is well established; however their combined impact is less well documented. Therefore, ...we investigated the combined effect of physical activity, nutrition and smoking status on prospective gain in body weight and waist circumference.
We used data of the prospective EPIC-PANACEA study. Between 1992 and 2000, 325,537 participants (94,445 men and 231,092 women, aged between 25-70) were recruited from nine European countries. Participants were categorised into two groups (positive or negative health behaviours) for each of the following being physically active, adherent to a healthy (Mediterranean not including alcohol) diet, and never-smoking for a total score ranging from zero to three. Anthropometric measures were taken at baseline and were mainly self-reported after a medium follow-up time of 5 years.
Mixed-effects linear regression models adjusted for age, educational level, alcohol consumption, baseline body mass index and follow-up time showed that men and women who reported to be physically active, never-smoking and adherent to the Mediterranean diet gained over a 5-year period 537 (95% CI -706, -368) and 200 (-478, -87) gram less weight and 0.95 (-1.27, -0.639) and 0.99 (-1.29, -0.69) cm less waist circumference, respectively, compared to participants with zero healthy behaviours.
The combination of positive health behaviours was associated with significantly lower weight and waist circumference gain.

Epidemiologic studies examining the association between specific fatty acids and colorectal cancer (CRC) risk are inconclusive. We investigated the association between dietary estimates and plasma ...levels of individual and total saturated (SFA), monounsaturated (MUFA), industrial‐processed trans (iTFA), and ruminant‐sourced trans (rTFA) fatty acids, and CRC risk in the European Prospective Investigation into Cancer and Nutrition (EPIC). Baseline fatty acid intakes were estimated in 450 112 participants (6162 developed CRC, median follow‐up = 15 years). In a nested case‐control study, plasma phospholipid fatty acids were determined by gas chromatography in 433 colon cancer cases and 433 matched controls. Multivariable‐adjusted hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were computed using Cox and conditional logistic regression, respectively. Dietary total SFA (highest vs lowest quintile, HRQ5vsQ1 = 0.80; 95%CI:0.69‐0.92), myristic acid (HRQ5vsQ1 = 0.83, 95%CI:0.74‐0.93) and palmitic acid (HRQ5vsQ1 = 0.81, 95%CI:0.70‐0.93) were inversely associated with CRC risk. Plasma myristic acid was also inversely associated with colon cancer risk (highest vs lowest quartile, ORQ4vsQ1 = 0.51; 95%CI:0.32‐0.83), whereas a borderline positive association was found for plasma stearic acid (ORQ4vsQ1 = 1.63; 95%CI:1.00‐2.64). Dietary total MUFA was inversely associated with colon cancer (per 1‐SD increment, HR1‐SD = 0.92, 95%CI: 0.85‐0.98), but not rectal cancer (HR1‐SD = 1.04, 95%CI:0.95‐1.15, Pheterogeneity = 0.027). Dietary iTFA, and particularly elaidic acid, was positively associated with rectal cancer (HR1‐SD = 1.07, 95%CI:1.02‐1.13). Our results suggest that total and individual saturated fatty acids and fatty acids of industrial origin may be relevant to the aetiology of CRC. Both dietary and plasma myristic acid levels were inversely associated with colon cancer risk, which warrants further investigation.
What's new?
The role of specific fatty acids in cancer development is not fully understood. In this large, prospective European study of colorectal cancer (CRC) risk, the authors found that dietary myristic and palmitic acids from dairy were inversely associated with CRC risk, as were total saturated (SFA) and monounsaturated (MUFA) fatty acids. Dietary industrially‐processed trans fatty acids (iTFA) were positively associated with rectal cancer. These results suggest that total and individual saturated fatty acids may be relevant to the aetiology of CRC.
The gut microbiome is increasingly implicated in colorectal cancer (CRC) development. A subgroup of patients diagnosed with CRC show high antibody responses to Streptococcus gallolyticus subspecies ...gallolyticus (SGG). However, it is unclear whether the association is also present pre‐diagnostically. We assessed the association of antibody responses to SGG proteins in pre‐diagnostic serum samples with CRC risk in a case–control study nested within a prospective cohort. Pre‐diagnostic serum samples from 485 first incident CRC cases (mean time between blood draw and diagnosis 3.4 years) and 485 matched controls in the European Prospective Investigation into Nutrition and Cancer (EPIC) study were analyzed for antibody responses to 11 SGG proteins using multiplex serology. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using multivariable conditional logistic regression models. Antibody positivity for any of the 11 SGG proteins was significantly associated with CRC risk with 56% positive controls compared to 63% positive cases (OR: 1.36, 95% CI: 1.04–1.77). Positivity for two or more proteins of a previously identified SGG 6‐marker panel with greater CRC‐specificity was also observed among 9% of controls compared to 17% of CRC cases, corresponding to a significantly increased CRC risk (OR: 2.17, 95% CI: 1.44–3.27). In this prospective nested case–control study, we observed a positive association between antibody responses to SGG and CRC development in serum samples taken before evident disease onset. Further work is required to establish the possibly etiological significance of these observations and whether SGG serology may be applicable for CRC risk stratification.
What's new?
The gut bacterium Streptococcus gallolyticus subspecies gallolyticus (SGG) has been associated with colorectal cancer (CRC), but whether this association exists pre‐diagnostically remains unknown. Here the authors performed a serological study in a prospective setting with samples from the European Prospective Investigation into Nutrition and Cancer (EPIC). They demonstrate a positive association of antibody responses to SGG proteins with CRC risk in pre‐diagnostic samples, implicating SGG serology as a new marker for risk of developing CRC.
Scope
Oleanolic acid (OA) is an important triterpenic compound found in olive oil, however little is known about its concentrations in human plasma. We aimed to determine plasma OA levels in a ...healthy Spanish population and compare them with estimates of dietary olive oil intake.
Methods and results
The final study sample included 141 individuals randomly selected from the European Prospective Investigation into Cancer and Nutrition Spanish cohort. Dietary olive oil intake was estimated using validated dietary history questionnaires. OA concentrations were determined in plasma (from the participants’ stored blood samples) using a HPLC‐MS method. Correlation coefficients between OA and olive oil intake were calculated, adjusting for center; sex; age; consumption of olives, apples, grapes, and red wine; and fasting state. The mean OA concentration in olive oil nonconsumers was 0.72 ng/mL (SD 0.82), while in the high olive oil intake group it was 1.32 ng/mL (SD 1.14). The fully adjusted partial Spearman correlations coefficients reached 0.36 (p‐value < 0.001) overall, varying minimally by sex and fasting state.
Conclusion
This is the first study providing steady‐state concentrations of triterpenes in humans. The results show that there was low‐to‐moderate correlation between OA concentrations and olive oil intake in this population.
Oleanolic acid (OA) is an important minor compound in olive oil with potentially beneficial health effects. This study determined concentrations of OA in blood in the general population for the first time and found a low‐to‐moderate link between blood OA and olive oil intake. Whether OA concentrations in blood are a good marker of olive oil consumed needs to be further clarified.
Introduction
There is still a scientific debate on the exact role played by obesity on stroke risk.
Objective
The aim of the study was to analyze the association between obesity, measured by ...different indices such as body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and a new one called A Body Shape Index (ABSI) and the risk of total and ischemic stroke.
Subjects/methods
A total of 41,020 subjects (15,490 men and 25,530 women) aged 29–69 years participated in the study. All participants were recruited between 1992 and 1996 and followed up until 2008 to ascertain incident cerebrovascular disease events. Cox proportional hazards models were designed to estimate the relative risk and 95 % CI between obesity and cerebrovascular disease incidence.
Results
After 13.8 years of follow-up, a total of 674 stroke cases (55.3 % in men) were registered (531 ischemic, 79 hemorrhagic, 42 subarachnoid hemorrhage and 22 unspecified). WC fourth quartile (HR 1.95; 95 % CI 1.20–3.19) and WHR fourth quartile (HR 1.58; 95 % CI 1.12–2.25) were positively associated with total stroke only in men. BMI was not associated with stroke incidence. The new index, ABSI, was significantly associated with total stroke incidence only in men (HR 1.54; 95 % CI 1.06–2.23).
Conclusions
Data from the Spanish EPIC cohort study show a strong association of WC and WHR with the relative risk of suffering a stroke only in men, while no associations were found for BMI. It supports the suggestion of other authors of using more than one obesity index in the study of stroke risk prediction.
Background: Overexpression of the receptor for advanced glycation end-product (RAGE) has been associated with chronic inflammation, which in turn has been associated with increased colorectal cancer ...risk. Soluble RAGE (sRAGE) competes with RAGE to bind its ligands, thus potentially preventing RAGE-induced inflammation.
Methods: To investigate whether sRAGE and related genetic variants are associated with colorectal cancer risk, we conducted a nested case–control study in the European Prospective Investigation into Cancer and Nutrition (EPIC). Plasma sRAGE concentrations were measured by ELISA in 1,361 colorectal cancer matched case–control sets. Twenty-four SNPs encoded in the genes associated with sRAGE concentrations were available for 1,985 colorectal cancer cases and 2,220 controls. Multivariable adjusted ORs and 95% confidence intervals (CIs) were computed using conditional and unconditional logistic regression for colorectal cancer risk and circulating sRAGE and SNPs, respectively.
Results: Higher sRAGE concentrations were inversely associated with colorectal cancer (ORQ5vs.Q1, 0.77; 95% CI, 0.59–1.00). Sex-specific analyses revealed that the observed inverse risk association was restricted to men (ORQ5vs.Q1, 0.63; 95% CI, 0.42–0.94), whereas no association was observed in women (ORQ5vs.Q1, 1.00; 95% CI, 0.68–1.48; Pheterogeneity for sex = 0.006). Participants carrying minor allele of rs653765 (promoter region of ADAM10) had lower colorectal cancer risk (C vs. T, OR, 0.90; 95% CI, 0.82–0.99).
Conclusions: Prediagnostic sRAGE concentrations were inversely associated with colorectal cancer risk in men, but not in women. An SNP located within ADAM10 gene, pertaining to RAGE shedding, was associated with colorectal cancer risk.
Impact: Further studies are needed to confirm our observed sex difference in the association and better explore the potential involvement of genetic variants of sRAGE in colorectal cancer development.
Sperm glycocalyx and plasma membrane undergo outstanding modifications during fertilization. However, it is unclear how in vitro capacitation time and acrosome reaction affect the specific location ...of boar sperm glycoconjugates. This study aimed to identify lectin binding patterns and to describe the sequential changes during different in vitro capacitation times (1 and 4 h) and acrosome reaction in boar spermatozoa. With Aleuria aurantia agglutinin (AAA), most uncapacitated cells were labelled in the postacrosomal region. Nevertheless, after 1 h of in vitro capacitation and the acrosome reaction, most AAA binding sites were in the acrosomal region. With Concanavalin A (ConA), most sperm were labeled in the postacrosomal region before and after capacitation. After the acrosome reaction induction, this pattern changed to a highly stained acrosomal and postacrosomal regions. Peanut agglutinin (PNA) binding sites were in the acrosomal region in uncapacitated and capacitated sperm. In acrosome reacted sperm after 4h capacitation, the most frequent pattern showed remaining positive labeling in the central area of the head. With Pisum sativum agglutinin (PSA), most uncapacitated cells showed a postacrosomal region staining. Nevertheless, faint stained all over the head and highly acrosomal region labelling was observed in the major part of capacitated and acrosome reacted sperm respectively. With Wheat germ agglutinin (WGA), the most representative pattern in uncapacitated, capacitated and acrosome reacted sperm was labelled in the acrosomal region. Regarding capacitation time, the most significant changes in the most representative pattern were observed in acrosome reacted spermatozoa after 4 h of in vitro capacitation.
Highlights
Lectins allow detailed descriptions of eight different populations in boar sperm.
Changes in lectin binding patterns during capacitation are time dependent.
Lectin binding patterns significantly change after 4 h of in vitro capacitation.
