Estimating the impact of obesity and metabolic phenotype on sickness absence. Results from the ICARIA study.

BACKGROUND AND AIMS: To assess the impact of obesity and being overweight on sickness absence (SA) as a function of healthy/unhealthy metabolic phenotype. METHODS AND RESULTS: A total of 173 120 healthy workers who underwent a routine check-up, consisting of a structured interview, anthropometric measurements and blood pressure and fasting blood analysis, were included as the study sample (67.1% males; 49.2% manual workers; mean age 40.6 ± 21.9 years). Workers were classified according to their body mass index (BMI) and metabolic phenotype. A metabolically unhealthy phenotype was defined as the presence of three or more of the following criteria: glycaemia ≥110 mg/dL or previously diagnosed type I/II diabetes or treatment for diabetes; triglycerides ≥150 mg/dL or lipid-lowering therapy; HDL <40/50 mg/dL M/F; blood pressure ≥130/85 mmHg or previously diagnosed hypertension or antihypertensive therapy; waist circumference >102/88 cm M/F. A one-year follow-up was conducted to evaluate the incidence of work-related and non-work-related SA (WRSA/NWRSA). The association of BMI with SA was tested using Poisson regression (standard error correction), segmenting on the basis of metabolic phenotype. The overall percentages of workers who were overweight, obese and/or had a metabolically unhealthy phenotype were 37.7%, 16.3% and 8.8%, respectively. BMI was associated with increased incidence of NWRSA in both phenotypes. It was also associated with WRSA in subjects with a BMI in the range of 35-39.99 kg/m2 and in metabolically healthy individuals. WRSA was lower in subjects with a BMI ≥40 kg/m2 and among metabolically unhealthy individuals. CONCLUSION: Obesity is associated with health problems that have a significant impact on SA.

[Beyond hypercoagulability in celiac disease]. / Más allá de la hipercoagulabilidad en la enfermedad celíaca.

In celiac disease (CD) there is a state of hypercoagulability and multiple factors have been found that may be involved. Cases of association of CD and antiphospholipid síndrome (APS) have been described and several observational studies have found an increase in antiphospolipid antibodies (AAF) in patients with CD, so both entities may be interrelated, increasing the risk of thrombotic events. A descriptive case of a patient who is simultaneusly diagnosed with CD and APS is presented.

The relationship between job stress and dyslipidemia.

AIMS: To investigate whether there is an association between job stress, lipid profile and dyslipidemia diagnosis. METHODS: This study used a questionnaire to evaluate job stress and lifestyle variables in 91,593 workers undergoing periodic checkups. Serum lipid levels were measured in all cases. RESULTS: The prevalence of job stress was 8.7% (95% CI, 8.5-8.8%). In bivariate analyses, job stress was significantly associated with previous dyslipidemia diagnosis (p < 0.001), lipid-lowering therapy (p < 0.001), and altered total-cholesterol (p = 0.001), HDL-cholesterol (p < 0.001) and LDL-cholesterol levels (p = 0.025). After adjusting for potential confounding variables, job stress was still associated with current dyslipidemia diagnosis (OR = 1.10; 95% CI, 1.04-1.17), high LDL-cholesterol (OR = 1.14; 95% CI, 1.05-1.23), low HDL-cholesterol (OR 1.08; 95% CI, 1.01-1.15), high total cholesterol/HDL-cholesterol ratio (OR 1.13; 95% CI, 1.05-1.23) and high LDL-cholesterol/HDL-cholesterol ratio (OR 1.11; 95% CI, 1.04-1.19). CONCLUSION: These results support the hypothesis of an association between job stress and lipid disturbances.

SEA 2022 Standards for Global Control of Cardiovascular Risk. / Estándares SEA 2022 para el control global del riesgo cardiovascular.

One of the objectives of the Spanish Society of Arteriosclerosis is to contribute to better knowledge of vascular disease, its prevention and treatment. It is well known that cardiovascular diseases are the leading cause of death in our country and entail a high degree of disability and health care costs. Arteriosclerosis is a multifactorial disease and therefore its prevention requires a global approach that takes into account the different risk factors with which it is associated. Therefore, this document summarizes the current level of knowledge and includes recommendations and procedures to be followed in patients with established cardiovascular disease or at high vascular risk. Specifically, this document reviews the main symptoms and signs to be evaluated during the clinical visit, the laboratory and imaging procedures to be routinely requested or requested for those in special situations. It also includes vascular risk estimation, the diagnostic criteria of the different entities that are cardiovascular risk factors, and makes general and specific recommendations for the treatment of the different cardiovascular risk factors and their final objectives. Finally, the document includes aspects that are not usually referenced in the literature, such as the organization of a vascular risk consultation.

High cardiovascular risk in Spanish workers.

BACKGROUND AND AIMS: To investigate the prevalence of high cardiovascular risk in the Spanish working population, and its distribution among different occupations and gender. METHODS AND RESULTS: Cross-sectional study of 309,955 workers (72.6% males, mean age 36.5 years, range 16-74 years), who underwent a routine medical check-up. Workers were classified as high, intermediate or low cardiovascular risk, according to the SCORE system. Workers with a relative risk greater than 4 were also considered as high-risk. The prevalence of high cardiovascular risk was 7.6% (95% CI 7.5-7.7) in males and 1.7% (95% CI 1.6-1.8) in females. After adjusting for age and gender, the prevalence of high cardiovascular risk was greater in workers from the Agriculture and Construction sectors than in those from Industry and Service sectors. The prevalence of high cardiovascular risk was higher in blue-collar than in white-collar occupations. CONCLUSIONS: A sizeable proportion of workers, especially blue-collar males, are at high cardiovascular risk. Knowledge of this risk for certain workers may serve as a basis for preventive strategies.

Lupus-associated endothelial dysfunction, disease activity and arteriosclerosis.

OBJECTIVE: To analyze endothelial function in systemic lupus erythematosus (SLE), and its relationship with disease activity and subclinical arteriosclerosis. METHODS: We studied a group of 26 patients with SLE and 21 age- and sex-matched controls. None of the patients or controls had had any ischemic event. Data were recorded on medical history, anthropometrics, prior treatment and the lupus activity index (LAI). Endothelial function was quantified by flow-mediated dilatation in the brachial artery. The presence of subclinical arteriosclerosis was assessed by the average intima-media thickness (IMT) on carotid ultrasound. RESULTS: The patients and the controls had a similar degree of carotid IMT (0.58+/-0.08 mm vs. 0.57+/-0.07 mm, NS) and a similar prevalence of carotid plaque (27% vs. 24%, NS). However, the SLE patients had worse endothelial function than the controls (FMD 12.4+/-4.4% vs. 16.9+/-5.5%, p<0.05). This difference remained after adjusting for age, smoking, body mass index, waist circumference, total cholesterol, triglycerides, HDL cholesterol, apolipoproteins A-1 and B100 and postmenopausal status. A significant association was found in the SLE patients between FMD and LAI (Spearman Rho -0.462, p<0.05). CONCLUSION: SLE-associated endothelial dysfunction is present in patients who have no prior ischemic events and with the same degree of subclinical arteriosclerosis as controls. The endothelial dysfunction is significantly associated with the degree of disease activity.

Effects of interferon-beta on plasma lipid and lipoprotein composition and post-heparin lipase activities in patients with chronic hepatitis C.

BACKGROUND: Interferon therapy has been shown to induce lipid abnormalities. AIM: We assessed the effects of interferon-beta on the lipoprotein profile and post-heparin lipase activities in 26 normolipaemic patients with chronic hepatitis C. METHODS: Interferon-beta was administered subcutaneously at doses of 6 x 106 U (units) three times a week, over 6 months, and lipoproteins and post-heparin lipases were measured at baseline and at the end of therapy. RESULTS: Plasma triglycerides increased by 21% due to preferential enrichment in those contained in the very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions. The concentration of cholesterol decreased slightly in the high density lipoprotein (HDL) subfractions. Lipoprotein lipase, but not hepatic lipase activity decreased by a 36%, and this change showed a significant negative correlation with changes in plasma triglycerides. Five patients (19.5%) responded to interferon-beta therapy. The lipoprotein profile was no different between responders and non-responders to therapy. CONCLUSIONS: Interferon-beta treatment in normolipaemic patients with chronic hepatitis C induced moderate disturbances in plasma lipoproteins, associated with inhibition of lipoprotein lipase activity.

Cisplatin, 5-fluorouracil, and high-dose folinic acid in patients with advanced unresectable head and neck cancer.

For patients with advanced, unresectable head and neck (HN) cancer, surgery and/or radiotherapy are the standard treatments but have poor results. A phase II trial of a continuous infusion of cisplatin, 5-FU, and high dose folinic acid (PFL) as induction chemotherapy in patients with previously untreated, locally advanced HN cancer was performed in an attempt to confirm the encouraging results reported by Dana Farber investigators using an identical regimen. Forty-five consecutive patients with unresectable HN cancer were treated every 28 days with a continuous infusion of cisplatin 25 mg/m(2)/day (days 1-5), 5-FU 800 mg/m(2)/day (days 2-6), and folinic acid 500 mg/m(2)/day (days 1-6). After three courses of chemotherapy, patients were treated with surgery and/or radiotherapy. Objective responses were observed in 26 of 38(69%) evaluable patients with 14(37%) clinical complete responses. Grade III-IV toxicity was important and consisted mainly of mucositis and neutropenia that were found in 47 and 18%, respectively , of patients after the first course. There was one toxic death. PFL is an active, toxic induction regimen for far-advanced HN cancer, yielding a response rate in the range of the widely used cisplatin and 5-FU (PF) schedule; a comparative trial is warranted before concluding that PFL is superior to the latter combination.

Weekly first-line chemotherapy of metastatic breast cancer with cyclophosphamide and epirubicin.

Forty-six patients with metastatic breast cancer who had not received previous chemotherapy for advanced disease entered a phase II trial of weekly chemotherapy with cyclophosphamide (250 mg/m2) + epirubicin (25 mg/m2) for 16 weeks. The overall response rate was 61% (95% confidence limits, 47-75%), with 10 complete and 17 partial responses. Toxicity was mild and confined to nausea and vomiting and asymptomatic neutropenia (except in 2 cases). Sixty-three per cent of patients had no side effects. Weekly cyclophosphamide + epirubicin is an active and nontoxic regimen for patients with metastatic breast cancer who have had no prior anthracycline-containing adjuvant chemotherapy.

Prevalence of atherogenic dyslipidemia: association with risk factors and cardiovascular risk in Spanish working population. "ICARIA" study.

OBJECTIVE: The aim of this study was to assess the prevalence of atherogenic dyslipidemia (AD) and the lipid triad (LT) in the working population in Spain, their associated variables and how far they are linked to cardiovascular risk (CVR). METHODS: Observational cross-sectional study of 70,609 workers (71.5% male (M), 28.5% female (F), mean age 39.2 ± 10), who attended medical checkups and agreed to participate. Plasma samples were analysed in a central laboratory. AD definition used was: triglycerides ≥150 mg/dl and HDL cholesterol <40 mg/dl (M)/<50 mg/dl (F) and LT when LDL cholesterol > 160 mg/dl is further added. Univariate comparisons in the absence and presence of AD and LT and the probability of AD according to different parameters and their possible association with CVR were assessed. CVR was stratified following the European SCORE model for low risk-population. RESULTS: 5.7% (95% CI 4.7-6.9) of the working population have AD and 1.1% (95% CI 1.0-1.2) LT. In univariate analysis, workers with AD and LT had a higher prevalence of obesity, hypertension, smoking and diabetes than those who had not (p < 0.001). In multivariate analysis, BMI, sex, age 40-49, diabetes, tobacco, uric acid, LDL or blood pressure significantly influenced the risk of AD. AD was significantly associated with CVR after adjusting for alcohol and obesity. However, most of the AD subjects (91.8%) were classified as low risk. CONCLUSIONS: About 6% of the working population in Spain meets AD criteria. Assuming that these subjects have increased CVR, AD allows to identify additional 5% of subjects with increased CVR to that one the SCORE model detects, helping to improve cardiovascular risk stratification.

Fasting apolipoprotein B48 is a marker for peripheral arterial disease in type 2 diabetes.

An earlier study showed that fasting and postprandial concentrations of apolipoprotein B48 were raised in patients with type 2 diabetes (DM2) and peripheral arterial disease (PAD) as compared with persons without DM2 or persons with DM2 but not PAD. The aim of this study was to confirm the association of PAD and B48 in a larger group of patients with DM2 and the relation of B48 with the preheparin lipoprotein lipase (LPL) mass. We studied 456 patients with DM2. PAD was defined as an ankle-brachial index (ABI) <0.9. Apolipoprotein B48 was quantified by ELISA. Apo B48 was significantly higher in the group with an ABI <0.9 than the groups with ABI of 0.9-1.3 and >1.3 (10.7 ± 6.28 vs. 9.24 ± 5.5 vs. 9.17 ± 8.8 mg/L, ANOVA test, p < 0.05). B48 was independently associated with an ABI <0.9 (OR 1.053; 95 % CI, 1.013-1.094; p < 0.05), together with smoking and duration of diabetes. The preheparin LPL mass was similar in the patients with and without PAD. In conclusion, we confirmed that fasting B48 is an independent marker of PAD in patients with DM2, unrelated to the preheparin LPL mass, statin therapy or glucose lowering treatment.

Postprandial apolipoprotein B48 is associated with asymptomatic peripheral arterial disease: a study in patients with type 2 diabetes and controls.

BACKGROUND: Postprandial hyperlipidemia is a common feature in type 2 diabetes; our aim was to investigate whether there is an association between subclinical peripheral arterial disease (PAD) and the levels of apolipoprotein B48, as a specific marker for postprandial lipidemia. METHODS: We enrolled 101 patients with type 2 diabetes and 73 controls free from clinical cardiovascular disease. Main outcome measures were the presence of subclinical PAD, assessed by the ankle-brachial index, and the intestinal particles measured as the concentration of apolipoprotein B48 at fasting and 4h after a mixed breakfast. RESULTS: No control had subclinical PAD. Of the 101 diabetic patients, 21 had subclinical PAD. The levels of apo B48, both fasting and postprandial, were only significantly raised in the diabetic patients who had PAD. The diabetic patients without vascular disease had similar concentrations of triglycerides and apo B48 to the controls. In binary logistic regression analyses, only smoking and postprandial B48 levels, in addition to diabetes, were independently associated with PAD. On the other hand, PAD but not diabetes was associated with the fasting and postprandial levels of apo B48. CONCLUSION: Our study suggests that apolipoprotein B48 levels might be a marker of occult PAD in patients suffering from type 2 diabetes mellitus. Accordingly, subclinical PAD should be taken into account in studies on postprandial lipidemia involving patients with diabetes.
