Body mass index and occupational accidents among health care workers in a large university hospital.

INTRODUCTION: Obesity is associated with a number of chronic diseases such as cardiovascular diseases and cancers. The association of obesity with occupational accidents has been suggested although the evidence is less convincing. The objective of the study is to analyse the relationship between BMI values and ergonomic accidents in a large University Hospital. METHODS: The relationship between body mass index (BMI) and the incidence of ergonomic occupational accidents over a period of 8 years was investigated in a cohort of employees of a large University Hospital, covering almost 27,000 person-years of observation. This relationship was stratified according to the variables age, gender, functional status within the organization and work schedule (part-time or full time). Height and weight were objectively measured, demographic data were obtained from the human resource department and the registration of ergonomic accidents was carried out by the safety and prevention department of the hospital. RESULTS: The number of ergonomic accidents, expressed as number/1000 person-years was higher for female employees compared to male employees, increased with age and markedly increased from functional class A (leading or expert function and higher educational level) to D (executive function in patient care and technical department). However, the incidence of ergonomic accidents accompanied by loss of working time was not significantly associated with BMI, independently of age and gender. In addition, the type of accident and the severity of the accidents expressed as the number of days absent from work were unrelated to BMI. CONCLUSION: No independent relationship between BMI and the incidence of ergonomic accidents could be identified in our cohort. Tailoring working conditions to individual BMI levels is not recommended.

Illness perceptions and health literacy are strongly associated with health-related quality of life, anxiety, and depression in patients with coronary heart disease: results from the EUROASPIRE V cross-sectional survey.

AIMS: To (1) Describe the sociodemographic and risk factor profiles of a sample of patients with coronary disease, (2) Explore associations between illness perceptions and health literacy with sociodemographic characteristics and risk factors, health-related quality of life (HRQoL), anxiety, and depression. METHODS AND RESULTS: Conducted as part of the ESC Prevention of CVD Project and EUROASPIRE V survey, patients were consecutively and retrospectively identified 6 months to 2 years after an acute event or elective procedure from 12 countries and interviewed. Three thousand four hundred and eight participants (76% male, mean age 64 years) were recruited, 16% were smokers, 38% obese, 60% physically inactive, and 41% hypertensive. Forty percent had attended cardiac rehabilitation. More threatening illness perceptions were associated with female gender (P < 0.0001), lower income (P < 0.0001), lower education (P = 0.02), obesity (P < 0.0001), sedentary behaviour (P < 0.0001), and diabetes (P < 0.0001). Poorer health literacy was associated with obesity (P = 0.02) and sedentary behaviour (P = 0.0001). Threatening illness perceptions were strongly associated with anxiety, depression, and poorer ratings of HRQoL after multivariable adjustment (all P < 0.001). Poor health literacy was associated with anxiety and depression (P < 0.0001) and poorer ratings of HRQoL (HeartQol scores P = 0.03). Results were consistent across regions of Europe, age, gender, and socio-economic strata. CONCLUSIONS: Interventions like cardiac rehabilitation should be targeted at vulnerable groups given the strong associations between more threatening illness perceptions, lower health literacy, lower HRQoL, and higher levels of anxiety and depression. The delivery and content of these interventions should be accessible for those with low health literacy.

Switch from BAK-preserved to preservative-free latanoprost decreases anterior chamber flare in POAG patients.

PURPOSE: To validate the hypothesis that BAK induces low-grade inflammation in the anterior chamber, we designed a study to investigate whether switching from BAK-preserved to preservative-free latanoprost in patients with primary open-angle glaucoma (POAG) would reduce the flare levels. PATIENTS: Forty-one eyes of twenty-two patients with primary open-angle glaucoma treated with BAK-preserved latanoprost for at least 6 months as monotherapy were included. Exclusion criteria included any use of topical eye drops other than latanoprost, pseudoexfoliation and pigment dispersion glaucoma, wearing of contact lenses and intraocular surgery in the past year. METHODS: At the start of the study, we measured baseline flare values. We then switched all patients to preservative-free latanoprost. After 1, 2, and 3 months, a routine ophthalmological examination was performed and flare measurement repeated. RESULTS: Thirty-three eyes were followed up throughout the entire 3-month period. One month after the switch to preservative-free latanoprost, a statistically significant mean drop in flare of - 0.96 ph/ms (P = 0.025) was observed. Mean flare decreased further by - 1.31 ph/ms (P = 0.0027) after 2 months and by - 1.25 ph/ms (P = 0.0041) after 3 months. CONCLUSION: The switch from BAK-preserved to preservative-free latanoprost induced a statistically significant reduction in mean flare value. Whereas our previous study showed an increase in flare when initiating treatment with BAK-preserved eye drops, this study shows a decrease in flare upon cessation of BAK-preserved drugs. The combined evidence from the two studies strongly suggests that in humans BAK exerts its effects not only on the ocular surface, but also at the level of the anterior chamber.

Smoking cessation in European patients with coronary heart disease. Results from the EUROASPIRE IV survey: A registry from the European Society of Cardiology.

OBJECTIVE: We investigated smoking cessation rates in coronary heart disease (CHD) patients throughout Europe; current and as compared to earlier EUROASPIRE surveys, and we studied characteristics of successful quitters. METHODS: Analyses were done on 7998 patients from the EUROASPIRE-IV survey admitted for myocardial infarction, unstable angina and coronary revascularisation. Self-reported smoking status was validated by measuring carbon monoxide in exhaled air. RESULTS: Thirty-one percent of the patients reported being a smoker in the month preceding hospital admission for the recruiting event, varying from 15% in centres from Finland to 57% from centres in Cyprus. Smoking rates at the interview were also highly variable, ranging from 7% to 28%. The proportion of successful quitters was relatively low in centres with a low number of pre- event smokers. Overall, successful smoking cessation was associated with increasing age (OR 1.50; 95% CI 1.09-2.06) and higher levels of education (OR 1.38; 95% CI 1.08-1.75). Successful quitters more frequently reported that they had been advised (56% vs. 47%, p < .001) and to attend (81% vs. 75%, p < .01) a cardiac rehabilitation programme. CONCLUSION: Our study shows wide variation in cessation rates in a large contemporary European survey of CHD patients. Therefore, smoking cessation rates in patients with a CHD event should be interpreted in the light of pre-event smoking prevalence, and caution is needed when comparing cessation rates across Europe. Furthermore, we found that successful quitters reported more actions to make healthy lifestyle changes, including participating in a cardiac rehabilitation programme, as compared with persistent smokers.

Immunogenicity and safety of the 13-valent Pneumococcal Conjugate vaccine in 23-valent pneumococcal polysaccharide vaccine-naive and pre-immunized patients under treatment with chronic haemodialysis: a longitudinal quasi-experimental phase IV study.

OBJECTIVE: To benchmark the immunogenicity of pneumococcal conjugated vaccine (PCV-13) versus pneumococcal polysaccharide vaccine (PPV-23) in haemodialysis patients pre-vaccinated or not with PPV-23. METHODS: The study is a longitudinal quasi-experimental phase IV study in chronic haemodialysis patients aged ≥50 years. Total (ELISA) and functional (opsonophagocytic assay) antibodies after pneumococcal vaccination were quantified at baseline, and after 28 and 365 days. Of 201 eligible patients, 155 were included. Patients were divided in four groups. PPV-23 naive patients were randomized to PPV-23 (40) or PCV-13 (40) vaccination. PPV-23-pre-vaccinated patients were categorized as being vaccinated more (40) or less (35) than 4 years before the study and all received PCV-13. RESULTS: Patients among the four groups had a significant ELISA antibody response for most serotypes that remained significant up to day 365 versus baseline. In PPV-23-naive patients, ELISA antibody titres were significantly higher among PCV-13 versus PPV-23 recipients for six serotypes (1.85-2.34-fold) after 28 days, and remained significantly higher for one serotype (6A, 1.57-fold) after 365 days. Following PCV-13 vaccination, increase in ELISA antibody titres was significantly higher among PPV-23-naive versus PPV-23-pre-vaccinated patients for 12 serotypes after 28 days (1.68-7.74-fold) and remained significantly higher in ten serotypes (1.44-3.29-fold) after 365 days. CONCLUSION: Immune response after PPV-23 and PCV-13 remains significant for at least 1 year in non-PPV-23-pre-vaccinated patients. Among vaccine-naive haemodialysis patients PCV-13 seems more immunogenic than PPV-23. Immune response to PCV-13 is weaker in PPV-23-pre-vaccinated compared with vaccine-naive patients.

Hair cortisol in relation to job stress and depressive symptoms.

BACKGROUND: Measurement of hair cortisol concentration (HCC) may be used as a biomarker for chronic stress. However, the association between stress and HCC has rarely been investigated in a working population. AIMS: To explore associations between (i) HCC and various stress measures and (ii) HCC and symptoms of depression in Belgian workers. METHODS: Hair samples were collected from workers in two production companies and cortisol content was determined by liquid chromatography tandem mass spectrometry. Participants completed a questionnaire including socio-demographics, health behaviours and standardized measures for assessing stress. RESULTS: After excluding those workers suffering from a psychiatric or neuroendocrine disease and those treated with glucocorticoids, there were a total of 102 workers with both questionnaire, cortisol results and anthropometric measures. Median HCC was 5.73 pg/mg hair (interquartile range = 4.52-9.06). No significant associations were found between cortisol and the standardized measures related to several work psychosocial risk factors. A significantly lower mean HCC was found in shift workers compared with dayworkers, adjusted for age. Additionally, a significant higher mean HCC was found in workers with symptoms of depression compared with those without symptoms of depression, after adjustment for age. CONCLUSIONS: HCC showed a limited applicability as a biomarker for job stress in this sample, although the results suggest this method may be a suitable marker for detecting early symptoms of depression. Further research is needed to investigate the applicability of HCC in the working environment and within job stress research.

Regional differences in the validity of self-reported use of health care in Belgium: selection versus reporting bias.

BACKGROUND: The Health Care Module of the European Health Interview Survey (EHIS) is aimed to obtain comparable information on the use of inpatient and ambulatory care in all EU member states. In this study we assessed the validity of self-reported information on the use of health care, collected through this instrument, in the Belgian Health Interview Survey (BHIS), and explored the impact of selection and reporting bias on the validity of regional differences in health care use observed in the BHIS. METHODS: To assess reporting bias, self-reported BHIS 2008 data were linked with register-based data from the Belgian compulsory health insurance (BCHI). The latter were compared with similar estimates from a random sample of the BCHI to investigate the selection bias. Outcome indicators included the prevalence of a contact with a GP, specialist, dentist and a physiotherapist, as well as inpatient and day patient hospitalisation. The validity of the estimates and the regional differences were explored through measures of agreement and logistic regression analyses. RESULTS: Validity of self-reported health care use varies by type of health service and is more affected by reporting than by selection bias. Compared to health insurance estimates, self-reported results underestimate the percentage of people with a specialist contact in the past year (50.5 % versus 65.0 %) and a day patient hospitalisation (7.8 % versus 13.9 %). Inversely, survey results overestimated the percentage of people having visited a dentist in the past year: 58.3 % versus 48.6 %. The best concordance was obtained for an inpatient hospitalisation (kappa 0.75). Survey data overestimate the higher prevalence of a contact with a specialist [OR 1.51 (95 % CI 1.33-1.72) for self-report and 1.08 (95 % CI 1.05-1.15) for register] and underestimate the lower prevalence of a contact with a GP [ORs 0.59 (95 % CI 0.51-0.70) and 0.41 (95 % CI 0.39-0.42) respectively] in Brussels compared to Flanders. CONCLUSION: Cautiousness is needed to interpret self-reported use of health care, especially for ambulatory care. Regional differences in self-reported health care use may be influenced by regional differences in the validity of the self-reported information.

Lipid lowering drug therapy in patients with coronary heart disease from 24 European countries--Findings from the EUROASPIRE IV survey.

OBJECTIVE: Since dyslipidaemia is one of the most important risk factors for coronary heart disease (CHD), lowering of LDL-cholesterol (LDL-C) causes significant reduction in morbidity and mortality, particularly in patients with established CHD. The aim of this survey was to assess how statins were prescribed in CHD patients at discharge after a coronary event from hospitals throughout Europe and how the intake of these drugs was reported by the patients when they were seen more than one year later in relationship with their achieved LDL-C levels. METHODS: 6648 CHD patients' data from centres in 24 European countries were gathered using standardized methods. Lipid measurements were performed in one central laboratory. Patients were divided in three groups: high-intensity statin therapy, moderate or low intensity statin therapy and no statin therapy at all. RESULTS: 90.4% CHD patients were on statin therapy at the time of discharge from the hospital which decreased to 86% one year later. Only 37.6% of these patients were prescribed a high-intensity statin at discharge which even decreased to 32.7% later. In only 6 countries (all of them high-income countries) the number of patients on a high-intensity statin therapy increased substantially after the hospital discharge. It is worrying that statin therapy was discontinued in 11.6% and that only 19.3% of all CHD patients achieved target values of LDL-C < 1.8 mmol/L at the time of interview. CONCLUSIONS: Too many CHD patients with dyslipidaemia are still inadequately treated and most of these patients on statin therapy are not achieving the treatment targets. Therapeutic control of LDL-C is clearly related to the intensity of lipid lowering drug regimen after the CHD event indicating that a considerable potential still exists throughout Europe to reduce CHD mortality and morbidity rates through more efficient LDL-C lowering.

[Levels of target achievement for major modifiable cardiovascular risk factors in Belgium]. / Niveaux d'atteinte des valeurs cibles thérapeutiques pour des facteurs majeurs modifiables du risque cardiovasculaire en Belgique.

Cardiovascular disease (CVD) is the main cause of premature mortality in Europe. The burden of CVD could be reduced by controlling the major modifiable CVD risk factors (dyslipidaemia, arterial hypertension, hyperglycaemia, smoking, and physical inactivity) through lifestyle and dietary changes and appropriate drug therapies. The objective of this article is to assess the level of target achievement for key modifiable CVD risk factors in Belgium by referring to the data from four recent studies. The overall results show that the main CVD risk factors are poorly controlled in patients with established CVD and in patients at high CVD risk. Therapeutic targets may be incompletely reached because of the suboptimal implementation of European guidelines for CVD prevention in routine clinical practice (insufficient lifestyle and dietary adaptations; poor applications of drug therapy to control blood pressure, dyslipidaemia and hyperglycaemia) or because of the insufficient efficacy of currently available treatment options in some patients. This review provides clear and updated evidence for non-target achievement for all major risk factors, with four different study designs and inclusion criteria; it highlights the need for a more comprehensive and intensive application of recommendations of the European guidelines for CVD prevention in Belgium.

SURF - SUrvey of Risk Factor management: first report of an international audit.

BACKGROUND: Despite the fact that subjects with established coronary heart disease (CHD) are at high risk of further events and deserve meticulous secondary prevention, current audits such as EUROASPIRE show poor control of major risk factors. Ongoing monitoring is required. We present a new risk factor audit system, SURF (Survey of Risk Factor management), that can be conducted much more quickly and easily than existing audit systems and has the potential to allow hospitals of all sizes to participate in a unified international audit system that will complement EUROASPIRE. Initial experience indicates that SURF is truly simple to undertake in an international setting, and this is illustrated with the results of a substantive pilot project conducted in Europe and Asia. METHODS: The data collection system was designed to allow rapid and easy data collection as part of routine clinic work. Consecutive patients (aged 18 and over) with established CHD attending outpatient cardiology clinics were included. Information on demographics, previous coronary medical history, smoking history, history of hypertension, dyslipidaemia or diabetes, physical activity, attendance at cardiac rehabilitation, cardiac medications, lipid and glucose levels (and HbA1c in diabetics) if available within the last year, blood pressure, heart rate, body mass index, and waist circumference were collected using a one-page data collection sheet. Years spent in full time education was added as an additional question during the pilot phase. RESULTS: Three European countries - Ireland (n = 251), Belgium (n = 122), and Croatia (n = 124) - and four Asian countries - Singapore (n = 142), Taiwan (n = 334), India (n = 97), and Korea (n = 45) - were included in the pilot study. The results of initial field testing were confirmed in that it proved possible to collect data within 60-90 seconds per subject. There was poor control of several risk factors including high levels of physical inactivity (41-45%), overweight and obesity (59-78%), and ongoing smoking (15%). There were lower levels of individuals attending cardiac rehabilitation in Asia. More Europeans than Asians reached the low-density lipoprotein cholesterol target of <2.5 mmol/l (66 vs. 59%) reflecting differences in medication usage. However, blood pressure control was superior in Asia, with 71% <140/90 compared with 66% of Europeans (NS). CONCLUSIONS: This phase of SURF has confirmed its ease of use which should allow wide participation and the collection of representative risk factor data in subjects with CHD as well as ongoing data collection to monitor secular trends in risk factor control. Notwithstanding that this is a pilot study, the results suggest that risk factor control, particularly for lifestyle-related measures, is poor in both Europe and Asia.

Behavioural and psychosocial correlates of nondipping blood pressure pattern among middle-aged men and women at work.

The underlying pathogenetic mechanisms of nondipping blood pressure (BP) pattern are not completely understood. Especially the role of psychosocial correlates remains unclear. The aim was to assess the association between nondipping BP pattern, behavioural and psychosocial factors in a sample of working men and women. The study sample included 167 working men and women aged 40-64 years from the BELSTRESS cohort. Socio-demographic, behavioural and psychosocial factors were assessed by self-administered questionnaires. Participants were medically examined and underwent an ambulatory BP monitoring during 24 h. Nondipping was defined when the average nocturnal decline in BP was <10%. The prevalence of nondipping for both systolic and diastolic BP was 7.8%. Nondipping was not significantly related to smoking, alcohol consumption and leisure time physical activity. A crude significant association was observed between nondipping and sleep problems. After adjusting for gender, education and body mass index, the risk for nondipping was associated with job strain, living alone, being unsatisfied about the contact with one's children, depressive symptoms and vital exhaustion. Nondipping BP pattern was consistently related to psychosocial factors in this study: positive associations were observed with measures of job strain, poor private life support (living alone and being unsatisfied about the contact with one's children) and mental health problems (depressive symptoms and vital exhaustion).

[Population-level changes to promote cardiovascular health]. / Zmeny na úrovni populace zamerené na podporu kardiovaskulárního zdraví

BACKGROUND: Cardiovascular diseases (CVD) cause 1.8 million premature (<75 years) death annually in Europe. The majority of these deaths are preventable with the most efficient and cost-effective approach being on the population level. The aim of this position paper is to assist authorities in selecting the most adequate management strategies to prevent CVD. DESIGN AND METHODS: Experts reviewed and summarized the published evidence on the major modifiable CVD risk factors: food, physical inactivity, smoking, and alcohol. Population-based preventive strategies focus on fiscal measures (e.g. taxation), national and regional policies (e.g. smoke-free legislation), and environmental changes (e.g. availability of alcohol). RESULTS: Food is a complex area, but several strategies can be effective in increasing fruit and vegetables and lowering intake of salt, saturated fat, trans-fats, and free sugars. Tobacco and alcohol can be regulated mainly by fiscal measures and national policies, but local availability also plays a role. Changes in national policies and the built environment will integrate physical activity into daily life. CONCLUSION: Societal changes and commercial influences have led to the present unhealthy environment, in which default option in life style increases CVD risk. A challenge for both central and local authorities is, therefore, to ensure healthier defaults. This position paper summarizes the evidence and recommends a number of structural strategies at international, national, and regional levels that in combination can substantially reduce CVD.

Job strain in relation to body mass index: pooled analysis of 160 000 adults from 13 cohort studies.

BACKGROUND: Evidence of an association between job strain and obesity is inconsistent, mostly limited to small-scale studies, and does not distinguish between categories of underweight or obesity subclasses. OBJECTIVES: To examine the association between job strain and body mass index (BMI) in a large adult population. METHODS: We performed a pooled cross-sectional analysis based on individual-level data from 13 European studies resulting in a total of 161 746 participants (49% men, mean age, 43.7 years). Longitudinal analysis with a median follow-up of 4 years was possible for four cohort studies (n = 42 222). RESULTS: A total of 86 429 participants were of normal weight (BMI 18.5-24.9 kg m(-2) ), 2149 were underweight (BMI < 18.5 kg m(-2) ), 56 572 overweight (BMI 25.0-29.9 kg m(-2) ) and 13 523 class I (BMI 30-34.9 kg m(-2) ) and 3073 classes II/III (BMI ≥ 35 kg m(-2) ) obese. In addition, 27 010 (17%) participants reported job strain. In cross-sectional analyses, we found increased odds of job strain amongst underweight [odds ratio 1.12, 95% confidence interval (CI) 1.00-1.25], obese class I (odds ratio 1.07, 95% CI 1.02-1.12) and obese classes II/III participants (odds ratio 1.14, 95% CI 1.01-1.28) as compared with participants of normal weight. In longitudinal analysis, both weight gain and weight loss were related to the onset of job strain during follow-up. CONCLUSIONS: In an analysis of European data, we found both weight gain and weight loss to be associated with the onset of job strain, consistent with a 'U'-shaped cross-sectional association between job strain and BMI. These associations were relatively modest; therefore, it is unlikely that intervention to reduce job strain would be effective in combating obesity at a population level.

Modest opposite associations of endogenous testosterone and oestradiol with left ventricular remodelling and function in healthy middle-aged men.

In healthy middle-aged men, endogenous testosterone does not seem to increase risk for cardiovascular disease (CVD). One explanation might be a differential effect of testosterone, and another, interference with oestradiol with respect to specific cardiovascular functions. To investigate these possibilities, we evaluated in a cross-sectional population of 1223 healthy men, aged 46 (6) years, associations between endogenous testosterone, oestradiol and left ventricular structure and function (echocardiography). Testosterone was inversely associated with ejection fraction (EF) and with more sensitive systolic tissue Doppler imaging indices. Oestradiol was positively associated with EF. These associations were confirmed by linear regression analyses, and consistent for calculated free as well as for total sex steroid concentrations. Standardized regression coefficients were -0.13 for testosterone (P < 0.01) and 0.12 for oestradiol (P < 0.01) for the association with EF, in a model which included height, waist circumference, triglycerides, glucose, systolic blood pressure, drug-treated hypertension, heart rate, haematocrit, current smoking, serum sampling time, age and excessive alcohol use. The study suggests an opposite link, albeit modestly, of testosterone and oestradiol with left ventricle systolic function in healthy middle-aged men. The finding provides a partial explanation for the overall neutral effect on CVD of testosterone in healthy middle-aged men.

Effect of a tailored behavior change program on a composite lifestyle change score: a randomized controlled trial.

To evaluate the effect of a tailored behavior change program on a composite lifestyle change score. A randomized controlled trial conducted in Belgium in 2007-08 with 314 participants allocated to a control and an intervention condition. The intervention was a tailored behavior change program (web-based and individual coaching). The dose of the coaching was chosen by the participants and registered. Outcome measures were weight, saturated fat intake, fruit and vegetable intake, physical activity, smoking status and a composite lifestyle change score. Mann-Whitney U-tests, Kruskal-Wallis tests, t-tests and one-way analyses of variance were used to compare the study conditions and three intervention dose groups (no/low, medium and high intervention dose). There were no significant differences between the study conditions or between the intervention dose groups for the individual lifestyle factors. The composite lifestyle change score was significantly higher in the high intervention dose group compared with the no/low intervention dose group (P = 0.009). The composite lifestyle change score was positively related to the intervention dose, while the individual lifestyle factors were not. Behavior change programs that target multiple lifestyle factors could be evaluated by using a composite lifestyle change score taking into account the intervention dose.

The relationship between diet and subclinical atherosclerosis: results from the Asklepios Study.

BACKGROUND/OBJECTIVES: Nutritional epidemiology shifted its focus from effects of single foods/nutrients toward the overall diet. Food-based dietary guidelines (FBDGs) are promoted worldwide to stimulate a healthy diet, including a variety of foods, to meet nutrient needs and to reduce the risk for non-communicable diseases. The objective of this study was to investigate whether adherence to the FBDG is associated with reduced femoral/carotid atherosclerosis and/or inflammation. SUBJECTS/METHODS: In October 2002, 2524 healthy men and women aged 35-55 years were recruited for the Belgian Asklepios cohort study. Subjects were extensively phenotyped, including echographic assessment of (carotid and femoral) atherosclerosis. A dietary index consisting of three subscores (dietary quality, diversity and equilibrium) was calculated to measure adherence to the Flemish FBDG, using data from a semi-quantitative food-frequency questionnaire. General linear models were used to investigate associations between these scores and cardiovascular (CV) risk factors and atherosclerosis and inflammation markers. RESULTS: Women had better overall dietary scores than men (69 vs 59%). Participants with higher dietary scores showed better age-adjusted CV risk profiles (lower waist/hip ratio, blood pressure, non-high-density lipoprotein-cholesterol, blood triglycerides and homocystein), although most of these associations were only significant in men. Higher dietary scores were also inversely associated with inflammation makers (interleukin-6 and leukocyte count). Associations between diet and atherosclerosis were only found for femoral atherosclerosis and significance disappeared after adjustment for confounders. CONCLUSIONS: Better adherence to the Flemish FBDG is associated with a better CV risk profile and less inflammation, mainly among men. There was no direct effect on the presence of carotid or femoral atherosclerosis.

Posttransplantation hypomagnesemia and its relation with immunosuppression as predictors of new-onset diabetes after transplantation.

New-onset diabetes after transplantation (NODAT) is a frequent complication and has an impact on patient and graft survival. Hypomagnesemia is common in both renal transplant recipients and in diabetics. This study examines the relationship between hypomagnesemia, NODAT and the type of immunosuppression in renal transplant recipients. We conducted a retrospective single-center analysis (2002-2008) in order to assess NODAT the first year posttransplantation as defined by American Diabetes Association criteria. Serum magnesium (Mg) levels were defined as the median of all Mg levels registered during the first month posttransplantation. Patients with NODAT (N = 75; 29.5%) versus non-NODAT had lower Mg levels (p < 0.001). Patients with an Mg level < versus > or = 1.9 mg/dL showed a faster development of NODAT (log-rank p < 0.001). Mg levels were lower in patients on calcineurin inhibitors (CNI) versus no CNI patients (p < 0.001). Mg levels, albumin, BMI, triglycerides, posttransplantation hyperglycemia, tacrolimus levels and the use of sirolimus were predictors of NODAT in the multivariate analysis. Hypomagnesemia was an independent predictor of NODAT in renal transplant recipients. We confirm that the use of CNI is associated with NODAT, but, to a large extent, this effect seems attributable to the induction of hypomagnesemia. After adjustment for Mg, sirolimus was also associated with NODAT.

HDL cholesterol protects against cardiovascular disease in both genders, at all ages and at all levels of risk.

OBJECTIVE: We aimed to clarify some previous inconsistencies regarding the role of high density lipoprotein cholesterol (HDL-C) as a CVD protective factor. METHODS: The SCORE dataset contained data on HDL-C for 104,961 individuals (45% women) without pre-existing coronary heart disease (CHD). These were from 7 pooled European prospective studies. The effect of HDL-C, both in quintiles and as a continuous variable, on risk of CVD and CHD mortality was examined, using Cox proportional hazards model, adjusted for age, total cholesterol, systolic blood pressure, smoking, diabetes and body mass index and stratified by gender, age group, country and category of SCORE CVD risk. RESULTS: A strong, graded, independent, inverse relationship between HDL-C and both CVD and CHD mortality was demonstrated. Adjusted hazard ratios per 0.5mmol/l increase in HDL-C were 0.60 (0.51, 0.69) and 0.76 (0.70, 0.83) in women and men, respectively for the CVD mortality endpoint. The corresponding hazard ratios were 0.53 (0.42, 0.68) and 0.79 (0.64, 0.98) in elderly women and men, respectively. The relationship was significant in all SCORE CVD risk strata and age groups. CONCLUSIONS: This multivariable analysis, the largest of its kind to date, has confirmed the inverse, independent, strong and graded relationship between HDL-C and both CVD and CHD mortality. We have clarified previous suggestions that the relationship is stronger in women and that it applies in all age groups. This is the first prospective study to demonstrate the independent relationship specifically in healthy elderly women and to show that the relationship holds at all levels of total CVD risk.

Prevalence and impact on quality of life of peripheral neuropathy with or without neuropathic pain in type 1 and type 2 diabetic patients attending hospital outpatients clinics.

AIMS: Diabetic polyneuropathy (DPN) without or with neuropathic pain (DPN-P) is one of the most frequent complications of diabetes. To better delineate their respective prevalences, we conducted a cross-sectional study that included 1111 patients (767 type 2 and 344 type 1 diabetic patients) followed up in diabetic outpatients clinics. The association of DPN and DPN-P with other diabetic complications, the impact on quality of life (QoL) and pain management were also investigated. METHODS: Two validated tools (Neuropen) and the DN4 questionnaire) were used to diagnose the two conditions. Pain intensity was measured using a visual analogue scale, and participants completed the 12-item Short-Form Health Survey to evaluate the physical and mental components of QoL. Univariate and multivariate models were used for the statistical analyses. RESULTS: The prevalence of DPN was 43% (95% CI 40.1-45.9), and was higher in type 2 (50.8%) than in type 1 (25.6%) diabetic patients. The prevalence of DPN-P was 14% (95% CI 12.1-16.2) which, again, was higher in type 2 (17.9%) than in type 1 (5.8%) patients. These prevalences both increased with age and diabetes duration. Nephropathy, obesity, low HDL cholesterol and high triglyceride levels were independently associated with DPN and/or DPN-P. Physical and mental components of QoL were significantly altered by DPN-P, but not DPN. Only half of the DPN-P patients were using analgesic treatment, while 28% were using anticonvulsants or antidepressants. CONCLUSION: DPN and DPN-P are frequent complications of diabetes, especially in type 2, and can be identified with inexpensive and easy-to-use screening tools. Despite its profound impact on QoL, DPN-P remains undertreated.
