Background and aim Prevalence rates of "metabolically healthy obese" (MHO) subjects vary depending on the criteria used. This study examined the prevalence and characteristics of MHO subjects and metabolically abnormal normal-weight subjects and compared the findings with the NHANES 1999–2004 study. The aims of the present study were, first, to determine the prevalence rates of MHO and MNHNO subjects using the same criteria as those of the National Health and Nutrition Examination Survey (NHANES) (1999–2004) study, and second to compare the prevalence and correlates of obese subjects who are resistant to the development of adiposity-associated cardiometabolic abnormalities (CA) and normal-weight individuals who display cardiometabolic risk factor clustering between the Spanish and the US populations. Methods and results Di@bet.es study is a national, cross-sectional population-based survey of 5728 adults conducted in 2009–2010. Clinical, metabolic, sociodemographic, and anthropometric data and information about lifestyle habits, such as physical activity, smoking habit, alcohol intake and food consumption, were collected. Subjects were classified according to their body mass index (BMI) (normal-weight, 2 ; overweight, 25–29.9 kg/m 2 ; and obese, >30 kg/m 2 ). CA included elevated blood pressure; elevated levels of triglycerides, fasting glucose, and high-sensitivity C-reactive protein (hs-CRP); and elevated homeostasis model assessment of insulin resistance (HOMA-IR) value and low high-density lipoprotein cholesterol (HDL-c) level. Two phenotypes were defined: metabolically healthy phenotype (0-1 CA) and metabolically abnormal phenotype (≥2 CA). The prevalence of metabolically abnormal normal-weight phenotype was slightly lower in the Spanish population (6.5% vs. 8.1%). The prevalence of metabolically healthy overweight and MHO subjects was 20.9% and 7.0%, respectively, while in NHANES study it was 17.9% and 9.7%, respectively. Cigarette smoking was associated with CA in each phenotype, while moderate physical activity and moderate alcohol intake were associated with being metabolically healthy. Olive oil intake was negatively associated with the prevalence of CA. Conclusions Smoking, physical activity level, and alcohol intake contribute to the explanation of the prevalence of CA in the Spanish population, as in the US population. However in Spain, olive oil intake contributes significantly to the explanation of the variance in the prevalence of CA.

The volume of the gastric reservoir appears crucial to explain the success of laparoscopic sleeve gastrectomy (LSG) in the treatment of morbid obesity. The aims of this study were to describe a new, easy model to estimate gastric reservoir volume after LSG; to evaluate the volumetric changes 1 year after surgery; and to analyze their relationship with weight loss. This is a prospective observational study of all patients undergoing LSG in the Department of Surgery at our institution. The gastric reservoir was evaluated radiologically considering the image as a complex geometrical shape with two components: a cylinder (gastric body) and a truncated cone (antrum). Radiologic assessment using this new model was performed at 1 and 12 months after surgery. Moreover, body mass index and percentage of excess weight loss (%EWL) were evaluated at 3, 6, 12, and 18 months after LSG. Forty-five patients (34 F/11 M) with a mean age of 46.9 years were included. A significant increase in total gastric reservoir volume (124.8 ± 58.7 and 188.6 ± 76.4 mL at 1 and 12 months, respectively; p = 0.001) was observed. No statistically significant differences were observed comparing volume of the two components at the two time points. The %EWL at 18 months was inversely correlated with reservoir volume changes at 12 months after LSG (p = 0.006). We describe an easy volumetric model to estimate the size of the gastric reservoir after LSG. Moreover, a direct relationship between an increase in gastric reservoir volume and a lower weight loss after surgery was documented.

The PREDAPS study aims to determine the risk of developing diabetes and the risk of vascular complications in patients with prediabetes and identify factors associated with those risks. It is a prospective observational study of a cohort of 1184 subjects with prediabetes and another cohort of 838 subjects with no alterations in glucose metabolism. The data at baseline were obtained from patients attending primary care centers in Spain throughout 2012. Subjects with prediabetes were classified into three groups: those who had only altered the fasting blood glucose levels -between 100 and 125mg/dl-, those who had only altered the HbA1c level -between 5.7 and 6.4% - and those who had altered both parameters. Information on sociodemographic characteristics, personal and family history, lifestyle and drug therapy was obtained from medical records and the interview with the doctor in the consultation. It was also performed a physical examination to determine weight, height, waist circumference and blood pressure were performed and blood and urine analysis. The PREDAPS study may help to reduce uncertainty in individual prevention strategies in subjects with prediabetes. Annual monitoring of patients recruited for five years will enable to know the risk of developing diabetes type 2 and the risk of macro-and microvascular complications in the three groups of subjects with prediabetes and determine the factors associated with those risks.

Patients with psychotic disorders have a higher risk of early mortality. In addition to unnatural causes (accidents, suicide), death due to cardiovascular (CV) reasons is two to four times more prevalent in these patients than in the general population. This non-systematic review of MEDLINE aims to clarify the role of all the determining factors are involved. Psychotic disorders are related to unhealthy life habits such as smoking, poor diet and physical inactivity. Neuroleptic drugs have also been studied as triggers of obesity and metabolic syndrome. Therefore, psychotic patients seem predisposed to suffer from several of the «classic» CV risk factors. It is not surprising that their scores on the CV risk scales (Framingham, SCORE) are higher than the general population. We also found publications that showed poorer management of primary and secondary prevention of CV disease. In addition, some biochemical factors (plasma levels of cortisol, ACTH, homocysteine, PCR) may indicate a vulnerability in psychosis per se, as well as the findings on hyperglycemia and insulin resistance in psychotic "drug naive" patients. These "non-classical" factors could alter the validity of CV risk scales designed for the general population. Furthermore, antipsychotic drugs could control intrinsic factors of psychosis (they have shown to reduce global mortality), and their role in CV mortality is not clear.

10.1007/s00592-013-0468-8 The aim of the study is to assess the prevalence of metabolic syndrome (MetS) in Spain using specific cutoff points for waist circumference (WC) (>94.5 cm for men and >89.5 cm for women) and evaluating the influence of several socio-demographic and economic factors. Data on MetS were obtained from a national study of 4,727 subjects from 18 to 90 years of age, conducted in Spain between 2009 and 2010 (The di@bet.es study). MetS was defined applying the new Harmonized definition (evaluating the use of abdominal obesity (AO) as a obligatory criterion for MetS or not) as well as with other widely used criteria. Results were then compared with data from previous studies. Multiple logistic regression models were used to evaluate the influence of different social factors. The age-standardized MetS prevalence was 38.37 % (CI 35.74¿40.99) in men and 29.62 % (CI 27.56¿31.69) in women, when AO was required as a diagnostic criterion; 42.13 % (CI 39.37¿44.89) and 32.31 % (CI 30.15¿34.47) in men and women, respectively, if AO was not considered mandatory. Prevalence of MetS increased with age (p < 0.001 for trend). Women with a lower educational level were more likely to have MetS (OR 4.4; 95 % CI: 2.84-6.7) as compared with those with a higher educational level. Subjects with MetS had a worse physical quality of life. The combination of AO, hypertension and carbohydrate alterations was the most common MetS¿ pattern. A high prevalence of MetS was detected in the Spanish population especially in men, the elderly and women with a low educational level.

The study was conducted in France, Germany, Greece, Spain, and the UK, and observed the course of diabetes therapy for up to 6 months. Direct medical costs were evaluated from the national health care system (third-party payer) perspective at 2006 prices.Results: Of the 1153 patients with type 2 diabetes, 1051 (91.2%) had follow-up visits in the 6 months after insulin initiation and were included in the cost analysis. In all countries in our study, mean total direct costs per patient increased in the 6-month follow-up period, compared with the 6-month period prior to insulin initiation, and ranged from €577 in Greece to €1402 in France. The incremental cost of adding insulin treatment ranged from €81 in France to €471 in Spain.Conclusion: In all countries, the mean total direct cost of care for diabetes increased after starting insulin. The breakdown of total direct costs by expenditure category varied considerably across countries, reflecting differences in resource use patterns, prices of medical resources, and different health care systems.Keywords: type 2 diabetes mellitus, costs, resource use, insulin

Despite the marked increase in cardiovascular risk factors in Spain in recent years, the prevalence and incidence of cardiovascular diseases have not risen as expected. Our objective is to examine the association between consumption of olive oil and the presence of cardiometabolic risk factors in the context of a large study representative of the Spanish population. A population-based, cross-sectional, cluster sampling study was conducted. The target population was the whole Spanish population. A total of 4572 individuals aged ⩾18 years in 100 clusters (health centers) were randomly selected with a probability proportional to population size. The main outcome measures were clinical and demographic structured survey, lifestyle survey, physical examination (weight, height, body mass index, waist, hip and blood pressure) and oral glucose tolerance test (OGTT) (75 g). Around 90% of the Spanish population use olive oil, at least for dressing, and slightly fewer for cooking or frying. The preference for olive oil is related to age, educational level, alcohol intake, body mass index and serum glucose, insulin and lipids. People who consume olive oil (vs sunflower oil) had a lower risk of obesity (odds ratio (OR)=0.62 (95% confidence interval (CI)=0.41–0.93, P=0.02)), impaired glucose regulation (OR=0.49 (95% CI=0.28–0.86, P=0.04)), hypertriglyceridemia (OR=0.53 (95% CI=0.33–0.84, P=0.03)) and low HDL cholesterol levels (OR=0.40 (95% CI=0.26–0.59, P=0.0001)). The results show that consumption of olive oil has a beneficial effect on different cardiovascular risk factors, particularly in the presence of obesity, impaired glucose tolerance or a sedentary lifestyle.

The present study was undertaken to examine the prevalence of urinary ACR (albumin/creatinine ratio) >30 mg/g and the associated clinical and environmental factors in a representative sample of the population of Spain. Di@bet.es study is a national, cross-sectional population-based survey conducted in 2009–2010. Clinical, metabolic, socio-demographic, anthropometric data and information about lifestyle habit were collected. Those subjects without KDM (known diabetes mellitus) were given an OGTT (oral glucose tolerance test). Albumin and creatinine were measured in a urinary sample and ACR was calculated. The population prevalence of ACR >30 mg/g was 7.65% (adjusted for sex and age). The prevalence of ACR >30 mg/g increased with age (P30 mg/g but after being adjusted for age, sex and hypertension, was significant only in those subjects with UKDM (unknown diabetes mellitus) {OR (odd ratio), 2.07 [95% CI (confidence interval), 1.38–3.09]; P30 mg/g was associated with hypertension [OR, 1.48 (95% CI, 1.12–1.95); P=0.001], HOMA-IR (homoeostasis model assessment of insulin resistance) [OR, 1.47 (95% CI, 1.13–1.92); P≤0.01], metabolic syndrome [OR, 2.17 (95% CI, 1.72–2.72); P30 mg/g in the Spanish population. The association between clinical variables and other potentially modifiable environmental variables contribute jointly, and sometimes interactively, to the explanation of prevalence of ACR >30 mg/g. Many of these risk factors are susceptible to intervention.

Objective. To evaluate the association between diabetes mellitus and health-related quality of life (HRQOL) controlled for several sociodemographic and anthropometric variables, in a representative sample of the Spanish population.Methods. A population-based, cross-sectional, and cluster sampling study, with the entire Spanish population as the target population. Five thousand and forty-seven participants (2162/2885 men/women) answered the HRQOL short form 12-questionnaire (SF-12). The physical (PCS-12) and the mental component summary (MCS-12) scores were assessed. Subjects were divided into four groups according to carbohydrate metabolism status: normal, prediabetes, unknown diabetes (UNKDM), and known diabetes (KDM). Logistic regression analyses were conducted.Results. Mean PCS-12/MCS-12 values were50.9±8.5/47.6±10.2, respectively. Men had higher scores than women in both PCS-12 (51.8±7.2versus50.3±9.2;P<0.001) and MCS-12 (50.2±8.5versus45.5±10.8;P<0.001). Increasing age and obesity were associated with a poorer PCS-12 score. In women lower PCS-12 and MCS-12 scores were associated with a higher level of glucose metabolism abnormality (prediabetes and diabetes), (P<0.0001for trend), but only the PCS-12 score was associated with altered glucose levels in men (P<0.001for trend). The Odds Ratio adjusted for age, body mass index (BMI) and educational level, for a PCS-12 score below the median was 1.62 (CI 95%: 1.2–2.19;P<0.002) for men with KDM and 1.75 for women with KDM (CI 95%: 1.26–2.43;P<0.001), respectively.Conclusion. Current study indicates that increasing levels of altered carbohydrate metabolism are accompanied by a trend towards decreasing quality of life, mainly in women, in a representative sample of Spanish population.

To date no nation-wide study has yet been undertaken in Spain to estimate the iodine deficiency. The aim was to evaluate iodine intake and its conditioning factors in a representative sample of the whole adult population.The Di@bet.es Study is a national, cross-sectional, population-based survey conducted in 2009-2010 in Spain.The median urinary iodine (UI) was 117.2 μg/L. Iodized salt (IS) was consumed by 43.9% of the population. The median UI in those who consumed IS and in those who did not consume IS was 131.1 and 110.8 μg/L respectively (p0.0001). The likelihood of having UI levels above 100 μg/L was significantly associated with the intake of IS (OR=1.47) and milk at least once a day (OR=1.22). Within each individual autonomous communities, the median UI levels in those who consumed IS correlated significantly with the median levels of those who did not consume IS (r=0.76, p=0.001).Though strictly speaking, Spain should be considered within the category of a country having an adequate iodine intake, the current value is too close to the cut point and does not guarantee that those groups with a greater need for iodine will have the required intake of iodine.

The different bariatric surgical techniques have an influence on food tolerance and the presence of vomiting. There have been few studies on the impact of these techniques on the quality of food intake.A prospective and comparative study was performed on a consecutive patient cohort operated on due to morbid obesity between May 2008 and November 2010. The quality of the diet was evaluated before and at 3, 6, 12 and 24 months postoperatively, using the questionnaire described by Suter et al.One hundred and five patients (64 vertical gastrectomy [VG] and 41 gastric bypass [GB]) completed the questionnaire before the surgery, and 87 at 3 months, 79 at 6 months, 53 at 12 months, and 18 at 24 months after surgery. The overall score of the questionnaire before surgery was 23.5 ± 2.6, with a significant difference at 3 months (20.4 ± 3.8, P.001), at 6 months (21.3 ± 4.6, P.001) and at 12 months (22.4 ± 3.3, P.044), and with no difference at 24 months (23.2 ± 2.5, P.622), after surgery. On comparing food intake of VG versus GB, the scores were similar before surgery (23.8 ± 2.4 vs 23.0 ± 2.8, P.125) as well as in the post-surgical follow up at 3 months (20.5 ± 3,9 vs 20.2 ± 3.7, P.599), 6 months (21.1 ± 5.3 vs 21.7 ± 3.4, P.243), 12 months (22.3 ± 3.3 vs 22.7 ± 3.4, P.140) and 24 months (22.9 ± 3.0 vs 23.6 ± 2.2, P = 1.00).The worsening of the quality of food intake is common in the first months after bariatric surgery, gradually improving and with no differences being seen between VG and GB.

Weight loss can improve metabolic control in patients with type 2 diabetes mellitus but the results of conventional therapy in this respect have been discouraging. Besides achieving significant and sustained weight loss, bariatric surgery can improve or resolve type 2 diabetes mellitus in the majority of patients. Anatomical modifications and changes in the secretion of intestinal hormones can explain the superiority of malabsorptive techniques. Currently, bariatric surgery offers a therapeutic alternative for type 2 diabetes patients with severe obesity and poor metabolic control under conventional therapy. Ongoing research will provide insights regarding the effect of intestinal hormones, new surgery techniques and the possible benefits of bariatric surgery in non-obese patients.

The effect of corticosteroids on beta cell function and humoral immune response in type 1 diabetes was tested in a 2-month trial conducted on 32 newly diagnosed patients (age 22.8 +/- 1.4 years, mean +/- S.E.M.). Prednisone was administered at immunosuppressive dosage (1 mg.kg-1.day-1) during the initial 10 days and at a maintenance dosage (0.3 mg.kg-1.day-1) for 50 days. Patients (n = 32) were enrolled within 6 weeks after diagnosis and matched in pairs for age, sex, presence of islet cell antibodies (ICA) and glucagon stimulated C-peptide levels. Insulin discontinuation was not contemplated. All the patients who received prednisone became ICA during treatment but in some (4 out of 10) this effect was only transient. Insulin antibodies (IA) were significantly lower in the prednisone group at second and third month (P < 0.05). No patient experienced complete remission but in 10 prednisone and 4 control patients the insulin requirements were below 0.3 IU/kg (P < 0.05). With similar glycemia the fasting C-peptide levels were higher in the treated patients. The profile of the insulin requirements during the follow-up was different in the two groups and at 9 months the prednisone group needed less insulin than the control (P < 0.05). Interestingly, within the prednisone-treated group and after 6 months, the levels of stimulated C-peptide improved significantly among the ICA+ patients while they were steady or declined in ICA- (P < 0.01). The analysis of variance covariance confirmed a positive interaction between ICA and the administration of prednisone on the outcome of beta cell function.(ABSTRACT TRUNCATED AT 250 WORDS)

The aims of this study were to determine the prevalence of hypertension in type 1 diabetes patients and to analyze its relationship with insulin resistance and other associated factors.A cross-sectional study on 291 patients with type 1 immune-mediated diabetes managed at two outpatient endocrinology clinics was performed. All participants were Caucasian, 18 years or older with type 1 diabetes duration of more than 6 months, who had completed the study protocol. Hypertension was defined as blood pressure ≥130/80 mmHg or use of antihypertensive medication, excluding angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers when used as treatment for micro- or macroalbuminuria.Hypertension was found in 87 [29.9% (95% confidence interval, or CI): 24.6%-35.2%] patients with type 1 diabetes. Hypertensive patients presented older age, male predominance, higher body mass index and overweight/obesity prevalence, and longer diabetes duration compared with normotensive patients. Insulin sensitivity quantified by estimated glucose disposal rate (eGDR) was lower in patients with hypertension compared with normotensives (5.2±1.4 vs. 9.1±1.2 mg kg(-1) min(-1), P.001) and showed a negative correlation with systolic blood pressure level (r=-0.612, P.01). In multivariate logistic regression analysis, eGDR, besides nephropathy, emerged significantly and independently associated with hypertension. An increment of 1 unit in insulin sensitivity assessed by eGDR was associated with a 5.7% decrease in hypertension prevalence (95% CI: 0.018-0.175) and the absence of nephropathy with an 88.2% decrease (95% CI: 0.15-0.92).Hypertension was present in approximately one third of patients with type 1 diabetes, especially in men, those with microangiopathy, overweight or obesity, older age and longer diabetes duration. Hypertension prevalence increased in parallel to the degree of renal impairment and was inversely related to insulin sensitivity.

Subtotal parathyroidectomy (SPTX) is the treatment of choice for hyperparathyroidism in a patient with multiple endocrine neoplasia type 1 (HPT-MEN-1). There are scarce data on the causes, timing, and appropriate surgical treatment of patients with recurrent HPT-MEN-1. The aim of this study was to investigate the timing, causes, site of recurrence, and surgical treatment of recurrent HPT-MEN-1 in patients who underwent SPTX. The study was a retrospective review of prospectively collected data on patients with HPT-MEN-1 with SPTX at two referral institutions. The data collected included the following: demographics, duration of follow-up, weight of resected parathyroid tissue, type of remnant, time to reoperation, cause/site of recurrence, and surgical treatment. We studied prognostic factors of recurrence. A total of 69 patients underwent SPTX and were followed for a mean of 75.3 months. After the surgery, 15 patients were left with a single “normal” gland and 54 with a 50- to 70-mg remnant of a partially excised abnormal gland. Nine patients (13%) had a recurrence within a mean of 85 months (12–144 months). Patients with a recurrence had been followed longer (115 vs. 66 months; p = 0.005). Five recurrences occurred in a parathyroid remnant, 3 in a previously “normal” gland; the fifth recurrence was in both a hyperplastic remnant and a fifth gland. Remedial surgery included five subtotal resections and four immediate parathyroid autotransplantations. Two patients had a second recurrence due to a supernumerary gland. Factors related with recurrence are the follow-up time (p

Introduction Bariatric surgery is the most effective option for the treatment of patients with a high risk of complications due to their obesity. However, it brings about a series of changes in calcium and vitamin D metabolism and an increase in resorption which lead to a loss of bone mass. Aim The objective of this study is to compare sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) as regards loss of bone mass using bone densitometry and bone remodelling markers. Patients and methods Fifteen women with morbid obesity were included, 8 by SG and 7 by RYGB, with a mean age of 47.8±9 and mean body mass index 43.3±3.4. Bone mass measurements were made on the lumbar spine, femur and distal radius, and the bone remodelling markers N-telopeptide (NTx) and bone alkaline phosphatase (BALP), as well as vitamin D levels before and 12 months after surgery. Results A significant bone mass loss was observed was observed with SG and RYGB, in the lumbar spine and hip, whilst no differences were observed in the radial. The percentage bone mass loss was less in the column and femur after SG than with RYGB, although it did not reach statistical significance, 4.6%±4.4 (mean±SD) and 6.3%±5.4 (mean±SD), respectively. At 12 months the Ntx increased for both types of surgery, and the BAP was only increased for SG. Conclusion SG causes less, although not significant, bone mass loss compared to RYGB.

Hyponatremia is considered the most frequent electrolyte disorder found in hospitalized patients and seems to be a prognostic factor during hospitalization.A prospective observational study was carried out in consecutive neurological patients admitted to our hospital over a 3-month period. Blood and urinary ionogram and osmolality were determined at entry and 3-5 days after admission in all patients with hyponatremia.Of the 130 patients admitted, 19 (14.6%) had hyponatremia. The causes of hyponatremia were as follows: inappropriate fluid replacement in 4 patients (21%), antihypertensive drugs in 4 (21%), syndrome of inappropriate secretion of antidiuretic hormone in 4 (21%), cerebral salt wasting syndrome in 2 (10%), and edematous status caused by liver disease in one and digestive loss in one (5%) each. Mortality was one (5%) and 0 (0%) among patients with and without hyponatremia, respectively.Hyponatremia is common in hospitalized neurological patients and can be misdiagnosed as a worsening of the main illness.

To establish the prevalence of psychoactive drug consumption in an obese population.We collected data from the clinical records of obese patients attending the Endocrinology and Nutrition Department and Psychiatry Department of Hospital del Mar between June 2005 and May 2006 (n=259). We recorded anthropometric, epidemiological and toxicological data. We also investigated the prevalence of concomitant diseases in this population.Psychoactive drugs were consumed by 37% of obese patients, mainly antidepressants (27%), anxiolytics, sedatives and hypnotics, and anticonvulsants. Moreover, 15% of all patients received combination treatment with two or more psychoactive drugs, mostly the association of an antidepressant and an antiepileptic drug.The prevalence of psychoactive drug consumption in our sample was higher than prevalence data observed in the general population, with antidepressant consumption being three-fold higher.

Udgivelsesdato: 2009-Jun-13 BACKGROUND: The incidence of type 1 diabetes in children younger than 15 years is increasing. Prediction of future incidence of this disease will enable adequate fund allocation for delivery of care to be planned. We aimed to establish 15-year incidence trends for childhood type 1 diabetes in European centres, and thereby predict the future burden of childhood diabetes in Europe. METHODS: 20 population-based EURODIAB registers in 17 countries registered 29 311 new cases of type 1 diabetes, diagnosed in children before their 15th birthday during a 15-year period, 1989-2003. Age-specific log linear rates of increase were estimated in five geographical regions, and used in conjunction with published incidence rates and population projections to predict numbers of new cases throughout Europe in 2005, 2010, 2015, and 2020. FINDINGS: Ascertainment was better than 90% in most registers. All but two registers showed significant yearly increases in incidence, ranging from 0.6% to 9.3%. The overall annual increase was 3.9% (95% CI 3.6-4.2), and the increases in the age groups 0-4 years, 5-9 years, and 10-14 years were 5.4% (4.8-6.1), 4.3% (3.8-4.8), and 2.9% (2.5-3.3), respectively. The number of new cases in Europe in 2005 is estimated as 15 000, divided between the 0-4 year, 5-9 year, and 10-14 year age-groups in the ratio 24%, 35%, and 41%, respectively. In 2020, the predicted number of new cases is 24 400, with a doubling in numbers in children younger than 5 years and a more even distribution across age-groups than at present (29%, 37%, and 34%, respectively). Prevalence under age 15 years is predicted to rise from 94 000 in 2005, to 160 000 in 2020. INTERPRETATION: If present trends continue, doubling of new cases of type 1 diabetes in European children younger than 5 years is predicted between 2005 and 2020, and prevalent cases younger than 15 years will rise by 70%. Adequate health-care resources to meet these children's needs should be made available. FUNDING: European Community Concerted Action Program.

To describe the characteristics at baseline of patients with type 2 diabetes mellitus who are initiating insulin.Prospective, observational multi-centre, open-label study in five European countries of patients with type 2 diabetes who were initiating insulin as part of their usual care.A total of 1172 patients were enrolled, with mean age 63.3 years and body mass index 29.9 kg/m(2). The majority (90%) of patients were taking one or more oral anti-diabetic agents; the percentage not taking anti-diabetic medication in the previous four weeks was highest in Germany (23.4%) and Spain (15.1%). The prevalence of microvascular diseases (range: 16.1%-36.1%) varied considerably between countries but for macrovascular (30.4%-38.6%) and other diabetes-related diagnoses (72.6%-76.6%) such as hypertension and dyslipidaemia the differences were less pronounced. In Germany, reported use of lipid-lowering (26.7%) and anti-platelet (27.1%) therapies was much less than in other countries (ranges: 53.2%-78.1% and 48.3%-61.1%, respectively). The majority of evaluable patients in each country had demonstrated poor control over a long period of time. Prior to initiating insulin, the most recent mean (+/-SD) HbA1(c) was 9.58 +/- 1.81%, fasting plasma glucose was 12.18 +/- 4.32 mmol/L and 78.5% had metabolic syndrome. IDF targets for HDL- and LDL-cholesterol, and blood pressure were met in 76.8%, 33.1% and 18.9% of patients, respectively.Insulin treatment was only initiated after HbA1(c) values were considerably higher than recommended in treatment guidelines for a sustained period of time.

Although metabolic syndrome is generally associated with type 2 diabetes mellitus, the present review emphasizes the possible presence of metabolic syndrome in type 1 diabetes and the impact of insulin resistance on micro- and macrovascular complications. Results of major intervention studies in type 1 diabetes have led to a generalized intensive insulin treatment, being an excessive weight gain one of the consequences. Since abdominal obesity and hyperglycemia are 2 components of the metabolic syndrome, an increase in the percentage of metabolic syndrome in patients with type 1 diabetes is not surprising, though its prevalence does not reach that reported for type 2 diabetes. For insulin sensitivity quantification in patients with type 1 diabetes the estimated glucose disposal rate (eGDR): it consists of calculating a score based on clinical factors of the patient, which shows an inverse relationship with the development of micro- and macrovascular complications. Moreover, insulin-resistance identification in type 1 diabetes may have therapeutic implications.

The HLA haplotype and its relationships with clinical, biological and immunological parameters were analyzed in a group of 87 Spanish type 1 diabetic patients at the clinical onset of the disease. The frequency of HLA-B18, DR3 and DR4 antigens was significantly increased whereas DR2, DR5 and DR7 were decreased in comparison with 189 healthy unrelated controls without family history of diabetes. DR3 showed a maximum relative risk for diabetes (5.5) whereas DR4 had a lower one (4.0). HLA-DR4 patients were younger at the time of diagnosis than DR4 negative (16.7 vs 21.4 years). We found no statistically significant relationship between HLA antigens and the other variables studied including the presence of islet cell antibodies, complement fixing islet cell antibodies, insulin autoantibodies, organ-specific antibodies, fasting and maximal glucagon stimulated C-peptide levels, initial glycemia and glycosylated hemoglobin.

A good metabolic control of patients with type 2 diabetes mellitus (DM2) will likely contribute to a decrease of their cardiovascular (CV) risk. Our aim was (1) to evaluate the degree of metabolic control with regard to glycemia, lipidemia and blood pressure (BP) and (2) to describe the prevalence of hypertension (HT) and hyperlipidemia in DM2 outpatients.TranSTAR is an on-line, case-control, cross-sectional study, which was performed in outpatient from all around Spain. Data on basal glycemia (BG), glycosilated hemoglobin (A1C), lipid profile, BP and personal history of CV diseases were obtained. The postprandial glycemia (PPG) was measured in a capillary sample at 1-3 hours post-meal. Standards of metabolic control of the Sociedad Española de Diabetes were applied to evaluate the degree of glycemic, lipidemic and BP control.371 pairs of patients were studied. In DM2 patients, a bad control was observed in 82.1% (CI 95%, 77.9-86.3) of them according to BG, in 88.4% (85.1-91.7) according to PPG and in 18.8% (14.3-23.3) according to A1C. An insufficient control in lipid profile was noticed in 63.3% (56.6-70.0) and in BP in 69.5% (64.2-74.8). 9.2% (0.9-17.5) and 20.5% (12.8-28.2) DM2 subjects had an unknown HT and hyperlipidemia, respectively.The rate of DM2 outpatients with a bad metabolic control is very high. The availability of data from our own population should contribute to a better clinical management of these patients.

Type 1 diabetes mellitus (DM) is a 'chronic' autoimmune disorder leading to the destruction of the pancreatic beta cell. The natural history of diabetes includes a long subclinical (prediabetes) period. The pathogenesis is multifactorial and characterized by the interaction of environmental factors, with predisposing genes, most of which are associated with the HLA DR DQ loci. The relatively recent development of worldwide incidence registries for Type 1 DM has allowed us to compare the epidemiological results obtained in most parts of the world. This approach is particularly valuable in analysing the effects of migration of populations from one area of the world where the incidence of Type 1 DM is different (usually lower) to a new geographic setting. Properly designed migrant studies may be valuable in uncovering whether the genetic background remains more important than the new 'exposure' as illustrated by the Sardinian migration to Lazio and Lombardy. The presence of some putative 'protective' environmental exposures or the absence of those prevalent in the country of origin may explain the usually lower Type 1 DM incidence observed in most countries (Chile, Peru, Mexico) sharing a 'Spanish caucasoid genetic pool', and even in relatively genetically homogeneous groups such as Japanese populations migrating to Hawaii. In fact, the disease is caused by both genetic and environmental factors and to convince the scientific community of this fact is a primary responsibility for epidemiologists.

In recent years there has been great concern that human insulin (HI) may induce fewer hypoglycaemic warning symptoms than porcine insulin (PI). We addressed this issue in eight patients aged 25.6 +/- 3.3 (SEM) years with Type I (insulin-dependent) diabetes mellitus of 15.1 +/- 3.7 years duration who complained that hypoglycaemia unawareness had appeared after transferring from PI to HI. Acute induction of hypoglycaemia was induced on two occasions with semisynthetic HI and purified PI under double-blind conditions. Blood glucose was first clamped for 2 h at 4.4-6.7 mmol l-1 with an intravenous infusion of HI or PI at 50 mU kg-1 h-1 and 20% glucose at a variable rate. Thereafter, insulin infusion alone was maintained for 100 minutes. Heart rate, arterial pressure, reflex times, autonomic and neuroglycopenic signs and symptoms were assessed every 10 min. Arterialized venous blood samples were taken to measure blood glucose every 10 min and catecholamines, insulin, glucagon, growth hormone, and cortisol every 20 min. Autonomic symptoms first appeared at a plasma glucose level of 2.92 +/- 0.21 mmol l-1 with HI vs 2.92 +/- 0.48 mmol l-1 with PI (NS). There were no significant differences between the two studies concerning any of the above mentioned clinical parameters or the counterregulatory hormone responses. A differential effect of insulin species on the ability to perceive hypoglycaemia in patients who ascribed diminished perception of hypoglycaemia to the use of HI was thus not observed.

The production and consumption of ultra-processed foods (UPF) has increased considerably during the last years worldwide. Collective evidence shows the association between UPF consumption and adverse health outcomes, including inflammatory gastro-intestinal disorders and obesity. The gut microbiota has been suggested as potential mediator of the effects of UPF consumption on metabolism and health. However, few studies have been conducted in order to elucidate these aspects. Therefore, the aim of the present study was to assess the cross-sectional associations between UPF consumption and gut microbiota in a population of senior subjects (n = 645) within the frame of the PREDIMED-Plus trial. Eligible participants were men and women (aged 55-75 years), without documented history of cardiovascular disease at enrollment, with overweight/obesity (body mass index ≤ 27 and

Objective: Our aim was to go deeper in the self-perception of weight and health status among the Spanish population, together with the connections of familiar relationships, physical activity practice, nutritional habits, and sleep patterns with the presence of obesity. Methods: A total of 1,000 subjects were enrolled in April 2017 in a representative adult Spanish population sample. Computer-assisted telephone interviewing was used and self-reported anthropometric data was obtained. Results: The population was composed of 51.3% women, with a mean age of 48 (36–63) years and a BMI of 23.2 (20.3–26.6). Although only 17.7% of subjects with self-reported obesity exhibited the self-perception to suffer from obesity, they referred a bad (16%) or regular (47%) self-perceived health status. Subjects who considered themselves as people with overweight and obesity displayed a BMI of 30.5 (28.7–32.2) and 37.1 (34.8–41.5), respectively. The obesity group displayed the highest percentage (71.9%) of participants with some first-degree relative with overweight or obesity (p < 0.001) in comparison with the other groups. The main reason put forward of preventing healthy eating among subjects with obesity was that they dislike healthy food. The multivariable logistic regression model for presence of obesity showed that there was a significant association with older age, presence of a first-degree relative with weight excess, a positive snacking habit, and daily alcohol consumption (p ≤ 0.019). Conclusion: The Spanish population has a low self-perception of obesity. Our data also reinforces the strong association between obesity and age, family interactions, usual snacking, and daily consumption of wine or beer.

Background: Severe postprandial hypoglycemia after bariatric surgery is a rare but invalidating complication. Our aim was to describe the different tests performed for its diagnosis and their outcomes as well as the response to the prescribed pharmacological and surgical treatments. Methods: Multicenter, retrospective systematic review of cases with recurrent severe postprandial hypoglycemia. Results: Over 11 years of follow-up, 22 patients were identified. The test most used to provoke hypoglycemia was the oral glucose load test followed by the mixed meal test which was the least standardized test. With pharmacological treatment, 3 patients were symptom-free (with octreotide) and in 12 patients hypoglycemic episodes were attenuated. Seven patients had persistent hypoglycemic episodes and underwent surgery. Partial pancreatectomy was performed in 3 patients who had positive selective arterial calcium stimulation, and nesidioblastosis was confirmed in 2 patients. Reconversion to normal anatomy was performed in 3 patients, and 1 patient underwent a resection of the ‘candy cane' roux limb, with resolution of hypoglycemia in all cases. Conclusions: There is high heterogeneity in the evaluation and treatment options for postoperative hypoglycemia. In patients that do not respond to pharmacological treatment, reconstruction of gastrojejunal continuity may be the safest and most successful procedure.
