Abstract
Purpose To determine the distribution of blood glucose and prevalence of diabetes in people above 60 years living in Tehran and their relationship with some variables. Methods In this cross-sectional population-based study, multistage cluster sampling was performed in the over 60-year-old population of Tehran. Blood samples were collected from all participants and the data of the history of diabetes and the use of blood glucose lowering agents or other drugs were collected using interviews. Results Of 3791 selected subjects, 3310 participated in the study (response rate = 87.3%). The mean blood Sugar (BS) and hemoglobin A1c (HbA1c) of the patients was 118.11(95% CI: 115.34 -120.88) and 6.12(95% CI: 6.05-6.2) respectively. The prevalence of diabetes was 29.03%(95% CI: 27.12-30.94) in all subjects, 26.83%(95% CI: 24.58-29.07) in men, and 31.2%(95% CI: 28.24-34.16) in women. Odds of diabetes was significantly worse in women. systolic blood pressure, diasstolic blood pressure, height, weight, waist circumference, wrist circumference, hip circumference, neck circumference and body mass Index were significantly higher in diabetic after adjusting for the effect of sex and age. The odds of blindness was 2.69 (95% CI: 1.10-6.59) times higher in diabetic than in non-diabetics. Conclusions On average, one in every three persons above 60 years of age was diabetic. Therefore, attention should be paid to this age group, especially women, due the higher prevalence of diabetes. All anthropometric measurements except height had a strong correlation with diabetes. Blindness was significantly more in diabetics.

Familial hypercholesterolemia in Gran Canaria: Founder mutation effect and high frequency of diabetes. CLINICA E INVESTIGACION EN ARTERIOSCLEROSIS : PUBLICACION OFICIAL DE LA SOCIEDAD ESPANOLA DE ARTERIOSCLEROSIS 2021; 33:247-253. [PMID: 33814196 DOI: 10.1016/j.arteri.2021.02.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 02/14/2021] [Accepted: 02/17/2021] [Indexed: 01/02/2023]
Abstract
INTRODUCTION Gran Canaria is a region of genetic isolation of familial hypercholesterolemia due to a founder mutation, p. [Tyr400_Phe402del], in the LDL receptor (LDLR) gene. Initial data suggest that its carriers could have a high prevalence of diabetes. MATERIAL AND METHODS Patients over 30 years of age with familial hypercholesterolemia and a confirmed mutation in LDLR were recruited from a tertiary hospital in Gran Canaria. The prevalence of diabetes and other clinical data were compared among carriers of p. [Tyr400_Phe402del] and those with other LDLR mutations. RESULTS 76.4% of the 89 participants were carriers of p.[Tyr400_Phe402del]. The prevalence of diabetes in this group was significantly higher (25 vs. 4%, P=.045). These cases also had a higher prevalence of cardiovascular disease and higher levels of LDL cholesterol and triglycerides. There were no differences in age, weight, body mass index, waist, age of onset, and time of statin treatment. However, they required PCSK9 inhibitors more often (51.5 vs 24%, P=.027). CONCLUSIONS The mutation p.[Tyr400_Phe402del] is associated with a high prevalence of diabetes, not explained by classic risk factors, such as age, obesity, or long-term use of statins.

The island of Gran Canaria: A genetic isolate for familial hypercholesterolemia. J Clin Lipidol 2019; 13:618-626. [PMID: 31153816 DOI: 10.1016/j.jacl.2019.04.099] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2018] [Revised: 04/24/2019] [Accepted: 04/30/2019] [Indexed: 11/16/2022]
Abstract
BACKGROUND Genetic diagnosis of familial hypercholesterolemia (FH) has not been universally performed in the Canary Islands (Spain). OBJECTIVES This study aimed to genetically characterize a cohort of patients with FH in the island of Gran Canaria. METHODS Study subjects were 70 unrelated index cases attending a tertiary hospital in Gran Canaria, with a clinical diagnosis of FH, according to the criteria of the Dutch Lipid Clinic Network. Given that 7 of the first 10 cases with positive genetic study were carriers of a single mutation in the LDLR gene [p.(Tyr400_Phe402del)], a specific polymerase chain reaction-based assay was developed for the detection of this variant as a first screening step on the remaining subjects. In those without this mutation, molecular diagnosis was completed using a next-generation sequencing panel including LDLR, APOB, PCSK9, LDLRAP1, APOE, STAP1, and LIPA genes and incorporating copy number variation detection in LDLR. RESULTS On the whole, 44 subjects (62%) had a positive genetic study, of whom 30 (68%) were heterozygous carriers of the p.(Tyr400_Phe402del) variant. Eleven subjects carried other mutations in LDLR, including the novel mutation NM_000527.4: c.877dupG; NP_000518.1: p.(Asp293Glyfs*8). An unclassified PCSK9 gene variant was found in one subject [(NM_174936.3:c.1496G>A; NP_777596.2: p.(Arg499His)]. Other single patients had mutations in APOB (heterozygous) and in LIPA (homozygous). All identified variants co-segregated with the disease phenotype. CONCLUSIONS These findings suggest a founder effect for the p.(Tyr400_Phe402del) LDLR mutation in Gran Canaria. A cost-effective local screening strategy for genetic diagnosis of FH could be implemented in this region.

Abstract
BACKGROUND The PREDATORR (PREvalence of DiAbeTes mellitus, prediabetes, overweight, Obesity, dyslipidemia, hyperuricemia and chronic kidney disease in Romania) study is the first national study analyzing the prevalence of diabetes mellitus (DM) and prediabetes, and their association with cardiometabolic, sociodemographic, and lifestyle risk factors in the Romanian population aged 20-79 years. METHODS This was an epidemiological study with a stratified, cross-sectional, cluster random sampling design. Sociodemographic, lifestyle, and anamnestic data were collected through self- and interviewer-administered questionnaires, and biochemical assays and oral glucose tolerance tests were performed. RESULTS In all, 2728 participants from 101 clinics of general practitioners were randomly selected, with a probability proportional to population size according to the 2002 Romanian Census. The participation rate was 99.6%. Impaired glucose regulation (prediabetes, known and unknown DM) was found in 28.1% of the study population. The overall age- and sex-adjusted prevalence of DM was 11.6% (95% CI 9.6%-13.6%), of which 2.4% (95% CI 1.7%-3.1%) had unknown DM. The prevalence of DM increased with age and was higher in men than in women. The age- and sex-adjusted prevalence of prediabetes was 16.5% (95%CI 14.8%-18.2%), with the highest percentage in the 60-79 year age group and in women. Obesity, abdominal obesity, dyslipidemia, low education level, and a family history of diabetes were associated with glucose metabolism disorders. CONCLUSIONS The PREDATORR study shows a high prevalence of impaired glucose regulation in the adult Romanian population, providing data on the prevalence of DM and prediabetes and their association with several risk factors.

Abstract
Little information is available on the prevalence of diabetes in people aged 55 years or older living on the African continent. We did a systematic review of the prevalence of type 2 diabetes in studies reported from Jan 1, 2000, to June 30, 2015, to provide accurate data for monitoring future trends. We did a comprehensive literature search using an African search filter and extracted and synthesised data from full papers. Among 1473 identified citations, 41 studies providing 49 separate data contributions involving 16 086 individuals met the inclusion criteria. The overall prevalence of diabetes was 13·7% (95% CI 11·3-16·3) and was higher in studies based on the oral glucose tolerance test (23·9%, 17·7-30·7, 12 contributions with 3415 participants) than fasting blood glucose criteria (10·9%, 8·9-13·0, 37 contributions with 12 671 participants; p<0·001). Prevalence was also higher in non-STEPS than in STEPS studies (17·1%, 95% CI 13·6-20·9) vs 9·6%, 6·6-13·0, p=0·003) and in urban than in rural settings (19·7%, 15·0-24·9 vs 7·9%, 4·6-12·0, p=0·0002), but did not differ significantly across age groups, sex, sample size, year of publication, region, or population coverage. These data highlight the need to reduce diabetes risk factors and implement adequate management strategies. In addition, they suggest that uniform diagnostic methods should be used across African countries and elsewhere to enable assessment of trends in diabetes prevalence and the success of diabetes prevention strategies. A collaborative initiative is required between key international and national diabetes and geriatric organisations to improve diabetes care for the older population in Africa and worldwide.

Abstract
OBJECTIVES The aim of this study was to estimate the prevalence of impaired fasting glucose (IFG) among Omani adults with no family history (FH) of diabetes and to investigate the factors behind the risk of developing type 2 diabetes (T2D), while excluding a FH of diabetes. METHODS A total of 1,182 Omani adults, aged ≥40 years, visited the Family Medicine & Community Health Clinic at Sultan Qaboos University Hospital, Oman, on days other than the Diabetes Clinic days, from July 2010 to July 2011. The subjects were interviewed and asked if they had T2D or a FH of T2D. RESULTS Only 191 (16%) reported no personal history of T2D or FH of the disease. Of these, anthropometric and biochemical data was complete in 159 subjects. Of these a total of 42 (26%) had IFG according to the American Diabetes Association criteria. Body mass index, fasting insulin, haemoglobin A1C and blood pressure (BP), were significantly higher among individuals with IFG (P <0.01, P <0.05, P <0.01 and P <0.01, respectively). In addition, fasting insulin, BP and serum lipid profile were correlated with obesity indices (P <0.05). Obesity indices were strongly associated with the risk of IFG among Omanis, with waist circumference being the strongest predictor. CONCLUSION Despite claiming no FH of diabetes, a large number of Omani adults in this study had a high risk of developing diabetes. This is possibly due to environmental factors and endogamy. The high prevalence of obesity combined with genetically susceptible individuals is a warning that diabetes could be a future epidemic in Oman.

Abstract
BACKGROUND Although diabetes is recognized as an emerging disease in African and Middle East, few population-based surveys have been conducted in this region. We performed a national survey to estimate the prevalence of type 2 diabetes (T2D) and to evaluate the relationship between this diagnosis, demographic and socioeconomic variables. METHODS The study was conducted on a random sample of 6580 households (940 in each region). 7700 subjects adults 35-70 years old were included in the analyses. T2D was assessed on the basis of a questionnaire and fasting blood glucose level according to the WHO criteria. Access to health care and diabetes management were also assessed. RESULTS Overall, the prevalence of T2D was 15.1%. There were sharp urban vs. rural contrasts, the prevalence of diabetes being twice higher in urban area. However, the ratio urban/rural varied from 3 in the less developed region to 1.6 in the most developed ones. A sharp increase of prevalence of T2D with economic level of the household was observed. For both genders those with a family history of T2D were much more at risk of T2D than those without. Awareness increase with age, economic level and were higher amongst those with family history of T2D. Drugs were supplied by primary health care centers for 57.7% with a difference according to gender, 48.9% for men vs. 66.0% women (p < 0.001) and area, 53.3% on urban area vs. 75.2% on rural one (p < 0.001). CONCLUSIONS Through its capacity to provide the data on the burden of diabetes in the context of the epidemiological transition that North Africa is facing, this survey will not only be valuable source for health care planners in Tunisia, but will also serve as an important research for the study of diabetes in the region where data is scarce. In this context, NCDs emerge as an intersectoral challenge and their social determinants requiring social, food and environmental health policy.

Abstract
There is concern about an emerging diabetes epidemic in Turkey. We aimed to determine the prevalence of diagnosed and undiagnosed diabetes, prediabetes and their 12-year trends and to identify risk factors for diabetes in the adult Turkish population. A cross-sectional, population-based survey, 'TURDEP-II' included 26,499 randomly sampled adults aged ≥ 20 years (response rate: 87 %). Fasting glucose and biochemical parameters were measured in all; then a OGTT was performed to identify diabetes and prediabetes in eligible participants. The prevalence of diabetes was 16.5 % (new 7.5 %), translating to 6.5 million adults with diabetes in Turkey. It was higher in women than men (p = 0.008). The age-standardized prevalence to the TURDEP-I population (performed in 1997-98) was 13.7 % (if same diagnostic definition was applied diabetes prevalence is calculated 11.4 %). The prevalence of isolated-IFG and impaired glucose tolerance (IGT), and combined prediabetes was 14.7, 7.9, and 8.2 %, respectively; and that of obesity 36 % and hypertension 31.4 %. Compared to TURDEP-I; the rate of increase for diabetes: 90 %, IGT: 106 %, obesity: 40 % and central obesity: 35 %, but hypertension decreased by 11 % during the last 12 years. In women age, waist, body mass index (BMI), hypertension, low education, and living environment; in men age, BMI, and hypertension were independently associated with an increased prevalence of diabetes. In women current smoking, and in men being single were associated with a reduced risk. These results from one of the largest nationally representative surveys carried out so far show that diabetes has rapidly become a major public health challenge in Turkey. The figures are alarming and underscore the urgent need for national programs to prevent diabetes, to manage the illness and thus prevent complications.

High levels of lipoprotein(a) are associated with a lower prevalence of diabetes with advancing age: results of a cross-sectional epidemiological survey in Gran Canaria, Spain.

Abstract
BACKGROUND Recent data suggest that concentrations of lipoprotein(a) [Lp(a)] may be inversely associated with the risk of diabetes. This study analyzed the relationships between Lp(a) and both diabetes and insulin resistance in an adult cohort from the island of Gran Canaria, Spain. METHODS Lp(a), homeostasis model assessment for insulin resistance (HOMA-IR) and conventional risk factors for diabetes were assessed in a sample of 1,030 adult individuals participating in a cross-sectional population-based epidemiological survey in the city of Telde. Diabetes was defined according to the WHO 1999 criteria, or as a previous diagnosis of diabetes. To identify patients at risk for diabetes, an Lp(a) cutoff level of 46 mg/dl was selected previously using classification and regression tree analysis. A multivariate logistic regression model with L2-regularization was used to assess the independent effect of Lp(a) on diabetes and its interactions with variables traditionally linked to the disease. Additionally, to investigate the effect of Lp(a) on insulin resistance, a parametric model was developed to describe the relationship between age and HOMA-IR values in subjects with levels of Lp(a) ≤ 46 or >46 mg/dl. RESULTS Along with variables known to be associated with diabetes, including age, mean blood pressure, serum triglycerides, and an interaction term between age and low HDL cholesterol, the logistic model identified a significant inverse association for diabetes and the interaction term between age and Lp(a) levels >46 mg/dl. According to the proposed parametric model, HOMA-IR was significantly lower in subjects of all ages who had Lp(a) levels >46 mg/dl. CONCLUSIONS These results suggest that the age-related increase in the probability of having diabetes is significantly lower in subjects with Lp(a) levels >46 mg/dl. This could be explained in part by a lower insulin resistance in this subset of the population.

Abstract
BACKGROUND Most studies describing an association between hypertension and an inflammatory/pro-thrombotic state do not assess insulin resistance. AIM To examine the association between hypertension and new cardiovascular risk factors when considering both classical risk factors and insulin resistance. METHODS In a population-based sample of 1030 subjects, clinical information and blood samples were obtained. Subjects were classified according to the presence or absence of hypertension, and insulin resistance was estimated using the homeostasis model of assessment (HOMA). To identify variables independently associated with hypertension, a four-model multiple logistic regression was performed: model 1 included novel risk factors (Plasminogen Activator Inhibitor- 1 [PAI-1], fibrinogen, von Willebrand Factor [vWF], lipoprotein(a), homocysteine and C-reactive Protein [CRP]); model 2, novel risk factors plus HOMA; model 3 included both classical (smoking, triglycerides, HDL cholesterol, total cholesterol, waist circumference and diabetes) and novel risk factors and model 4, model 3 plus HOMA. All were adjusted for age, BMI and gender and compared using Akaike's Information Criterion (AIC). RESULTS In model 1, only PAI-1, age and BMI showed association with hypertension.When HOMA and classical risk factors were also included, PAI-1 was replaced by triglyceride, smoking and diabetes. The lowest AIC value (best adjustment) was displayed by model 4, comprising all of the variables. Only age, BMI, HOMA and smoking remained significantly associated with hypertension. CONCLUSIONS The novel cardiovascular risk factors assessed do not add information as markers of hypertension when classical risk factors or insulin resistance are included in the evaluation.

Abstract
OBJECTIVE To estimate the prevalence of diabetes mellitus and impaired fasting glycemia in an adult population living in Madrid (Spain). METHODS In this cross-sectional, population-based survey, we studied 1,344 adults aged 31-70 years, randomly selected from the population living in 14 primary care districts of the Madrid region. All participants underwent a clinical evaluation that included a clinical interview, physical examination and fasting blood analysis (glycemia, cholesterol and triglyceride levels). The participants were considered to be diabetic if they had been previously diagnosed with diabetes by their general physician or had a fasting glycemia ≥ 126 mg/dl without a previous diabetes diagnosis. Impaired fasting glycemia was defined as fasting glycemia between 100mg/dl and 125 mg/dl in non-diabetic participants. RESULTS The sex- and age-adjusted prevalence figures for diabetes and impaired fasting glucose were 6.6% (95% CI: 5.9-8.7) and 14.1% (95% CI: 12.1-15.8), respectively. A substantial proportion of diabetic patients [17.2% (95% CI: 10.9-23.5)] had not been previously diagnosed. The variables independently associated with diabetes were age, male gender, abdominal obesity and hypertension. CONCLUSIONS Our prevalence figure for diabetes is similar to those reported in other Spanish regions. The high frequency of impaired fasting glucose is worrisome, particularly when combined with obesity, as this association confers a high risk for developing diabetes mellitus.

Abstract
Background and Aim Diabetic dyslipidaemia is common in type 2 diabetes (T2D) and insulin resistance and often precedes the onset of T2D. The Taq1B polymorphism in CETP (B1 and B2 alleles) (rs708272) and the G-250A polymorphism in LIPC (rs2070895) are associated with changes in enzyme activity and lipid concentrations. Our aim was to assess the effects of both polymorphisms on the risk of T2D. Methods and Results In a case-control study from the population-based Telde cohort, both polymorphisms were analysed by PCR-based methods. Subjects were classified, according to an oral glucose tolerance test, into diabetic (N = 115) and pre-diabetic (N = 116); 226 subjects with normal glucose tolerance, matched for age and gender, were included as controls. Chi-square (comparison between groups) and logistic regression (identification of independent effects) were used for analysis. The B1B1 Taq1B CETP genotype frequency increased with worsening glucose metabolism (42.5%, 46.1% and 54.3% in control, IGR and diabetic group; p = 0.042). This polymorphism was independently associated with an increased risk of diabetes (OR: 1.828; IC 95%: 1.12–2.99; p = 0.016), even after adjusting by confounding variables, whereas the LIPC polymorphism was not. Regarding the interaction between both polymorphisms, in the B1B1 genotype carriers, the absence of the minor (A) allele of the LIPC polymorphism increased the risk of having diabetes. Conclusion The presence of the B1B1 Taq1B CETP genotype contributes to the presence of diabetes, independently of age, sex, BMI and waist. However, among carriers of B1B1, the presence of GG genotype of the -250 LIPC polymorphism increases this risk further.

North African influences and potential bias in case-control association studies in the Spanish population. PLoS One 2011; 6:e18389.

Abstract
Background Despite the limited genetic heterogeneity of Spanish populations, substantial evidences support that historical African influences have not affected them uniformly. Accounting for such population differences might be essential to reduce spurious results in association studies of genetic factors with disease. Using ancestry informative markers (AIMs), we aimed to measure the African influences in Spanish populations and to explore whether these might introduce statistical bias in population-based association studies. Methodology/Principal Findings We genotyped 93 AIMs in Spanish (from the Canary Islands and the Iberian Peninsula) and Northwest Africans, and conducted population and individual-based clustering analyses along with reference data from the HapMap, HGDP-CEPH, and other sources. We found significant differences for the Northwest African influence among Spanish populations from as low as ≈5% in Spanish from the Iberian Peninsula to as much as ≈17% in Canary Islanders, whereas the sub-Saharan African influence was negligible. Strikingly, the Northwest African ancestry showed a wide inter-individual variation in Canary Islanders ranging from 0% to 96%, reflecting the violent way the Islands were conquered and colonized by the Spanish in the XV century. As a consequence, a comparison of allele frequencies between Spanish samples from the Iberian Peninsula and the Canary Islands evidenced an excess of markers with significant differences. However, the inflation of p-values for the differences was adequately controlled by correcting for genetic ancestry estimates derived from a reduced number of AIMs. Conclusions/Significance Although the African influences estimated might be biased due to marker ascertainment, these results confirm that Northwest African genetic footprints are recognizable nowadays in the Spanish populations, particularly in Canary Islanders, and that the uneven African influences existing in these populations might increase the risk for false positives in association studies. Adjusting for population stratification assessed with a few dozen AIMs would be sufficient to control this effect.

Abstract
OBJECTIVE To characterize the cardiovascular risk profile of subjects categorized differently by A1C- and oral glucose tolerance test (OGTT)-based diagnostic criteria for diabetes according to the recommendations of the American Diabetes Association (ADA). RESEARCH DESIGN AND METHODS An OGTT, A1C, and several cardiovascular risk factors were assessed in 964 individuals without known diabetes participating in a cross-sectional epidemiological survey in Gran Canaria, Spain. RESULTS Taking the OGTT as the gold standard, the sensitivity and specificity of an A1C value ≥ 6.5% were 38.7 and 99.6%, respectively. Subjects who fulfilled A1C-based criterion presented greater measures of BMI and waist circumference, lower values for HDL cholesterol, and higher values for fasting plasma glucose, homeostasis model assessment of insulin resistance, and fibrinogen than subjects with diabetic OGTT but A1C <6.5%. CONCLUSIONS Newly diagnosed diabetic individuals who fulfill A1C-based diagnostic criterion for the disease display a more unfavorable cardiovascular risk profile than individuals who only meet the glucose-based criteria.

Abstract
Atherosclerosis has been correlated with known cardiovascular risk factors such as serum glucose or lipid levels. Because congenital heart disease patients tend to survive until adulthood, atherosclerosis has also become a matter of concern in these patients. One hundred fifty-eight congenital heart disease patients and 152 patients selected at random from the population were studied and compared to determine serum glucose, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein cholesterol, and triglycerides levels. Both groups had similar socioeconomic status levels and the same environmental influences. Significant differences were seen between congenital heart disease patients and the control group, after sex, age, and body mass index adjustment, in fasting plasma glucose (97.7 [94.2-101.2] vs 86.9 [83.2-90.7], P < .001), total cholesterol (171.5 [165.7-177.3] vs 199.8 [90.7-206.0], P < .001), LDL cholesterol (103.9 [98.8-108.8] vs 123.8 [118.5-129.1], P < .001), and high-density lipoprotein cholesterol (48.1 [46.2-50.0] vs 54.2 [52.1-56.2], P < .001) levels. Nonsignificant differences were seen in triglycerides concentrations. Those patients with ventricular septal defect, coarctation of the aorta, and cyanosis had the lowest total cholesterol and LDL cholesterol concentrations. Congenital heart disease patients have lower plasma cholesterol concentrations and higher serum glucose levels than noncongenital ones.

Abstract
AIMS The aims of this study is to assess whether and to what extent there is clustering of cardiovascular risk factors in the IFG phase in the Mongolian population, China. METHODS Total 2589 Mongolians aged 20 years or more were recruited as study subjects. Data on demographic characteristics, lifestyle risk factors, family history of hypertension, medical history and fasting plasma glucose were obtained, and relationship between clustering of cardiovascular risk factors and risk of IFG and diabetes analyzed for all individuals. RESULTS The proportions of 3 risk factors clustering were higher in diabetes than in IFG, and higher in IFG than in normal FPG (both P<0.01). After adjustment for age and sex, both IFG and diabetes were associated with mutually clustering of 6 risk factors; odds ratio (OR) of IFG associated with 1, 2 and >or=3 factors was 1.43 (1.02, 1.99), 2.22 (1.58, 3.12) and 4.49 (3.24, 6.22), respectively, and OR of diabetes associated with 1, 2 and >or=3 factors was 2.01 (0.70, 5.76), 5.47 (2.03, 14.71) and 14.30 (5.55, 36.83), respectively. CONCLUSIONS There was clustering of risk factors in the phase of IFG among Mongolian people, so intervention measures should be taken to prevent diabetes and other cardiovascular diseases among the individuals with IFG.

Abstract
The purpose of this study was to analyze the outcomes of major lower extremity amputations (MLEAs) in a series, including diabetic patients, with the aim to study whether diabetes mellitus is a risk factor of in-hospital mortality and perioperative complications. A retrospective analysis of 283 MLEAs (221 of these patients were diabetic and 62 were nondiabetic) performed between January 1, 1998, and December 31, 2008, at the General Surgery Department and Diabetic Foot Unit of La Paloma Hospital in Las Palmas de Gran Canaria (Canary Islands) was done. The significant risk factors of mortality were >" xbd="324" xhg="301" ybd="1481" yhg="1446"/>75 years of age (odds ratio [OR] = 4.1, 95% confidence interval [CI] = 1.4-11.7), postoperative cardiac complications (OR = 12.3, 95% CI = 3.7-40.2) and postoperative respiratory complications (OR = 3.8, 95% CI = 1.0-13.3). No statistically significant risk factors were found related to the presence of systemic and wound-related complications. In diabetic patients, the significant risk factors of mortality were postoperative cardiological complications (OR = 13.6, 95% CI = 3.1-59.6), postoperative respiratory complications (OR = 5.9, 95% CI = 1.0-35.5), and first episode of amputation (OR = 5.9, 95% CI = 1.4-24.3). There were no statistically significant differences in the outcome of major amputations between diabetic and nondiabetic patients. Hospital stay was significantly longer in diabetic patients ( P < .01) though when the patients with diabetic foot infections were excluded, this difference was not found.

Abstract
BACKGROUND An exceptionally high incidence of diabetes-related end-stage renal disease (DM-ESRD) has been reported in the Canary Islands. This phenomenon was attributed to an increased prevalence of diabetes in this community. We compared the incidence of DM-ESRD in the Canary Islands with the rest of Spain among the estimated number of individuals at risk (people with diabetes in the population). METHODS The population-at-risk was calculated using census population figures and estimates of self-reported diabetes prevalence from the Spanish National Health Survey in the years 2003 and 2006. The incidence of DM-ESRD for the same years was obtained through Spanish regional registries. The independent effect of age, community of residence and calendar year was estimated with a Poisson regression model. Age-standardized acceptance rate ratios were calculated for each community. RESULTS Overall DM-ESRD incidence in the Canary Islands population-at-risk was 1209.9 per million population (pmp) in 2003 and 1477.3 pmp in 2006. Rates for the remaining Spanish regions ranged from 177.3-984.9 pmp. The incidence was higher in the Canary Islands across all age groups, but was most striking for patients > or =75 years. Diabetes prevalence in the general population was greater in the two youngest age strata and diminished from 75 years on in the Canary Islands, in comparison with other areas of Spain. Using a cluster of three communities with the lowest incidence as a reference, the relative risk of DM-ESRD in the Canary Islands population-at-risk was 3.88 [95% confidence interval (CI): 3.07-4.89]. Age-standardized acceptance ratios (95% CI) in the Canary Islands were 2.21 (1.85-2.61) in 2003 and 2.73 (2.34-3.17) in 2006. CONCLUSIONS Individuals with diabetes in the Canary Islands present a disproportionately high incidence of ESRD. Diabetic Canary inhabitants are exposed to the disease for a longer time and therefore, may be more vulnerable to the development of chronic diabetes complications, including ESRD.

Abstract
AIMS The aims of this study is to assess the prevalence of diabetes and IFG and compare the risk factors between diabetes and IFG in the Mongolian population, China. METHODS Data on demographic characteristics, lifestyle risk factors, family history of hypertension, medical history and fasting plasma glucose were obtained and analyzed for all individuals. RESULTS Total 2589 Mongolians aged 20 years or more were recruited as study subjects. The overall prevalence of diabetes and IFG was 3.7% (males 3.9%; females 3.5%) and 18.5% (males 17.7%; females 19.0%), respectively. Multivariate logistic analysis showed that diabetes was significantly associated with age (odds ratio: 1.26), overweight (1.86), high triglycerides (1.96), family history of hypertension (1.86), heart rate (1.05) and high C-reactive protein (3.59), and IFG significantly associated with age (odds ratio: 1.11), low high-density lipoprotein-cholesterol (1.80), family history of hypertension (1.60), heart rate (1.03) and high C-reactive protein (2.73). CONCLUSIONS IFG were common among Mongolian people living in the northeast of China. IFG has partly same risk factors as diabetes, and prevalence of some cardiovascular risk factors and number of risk factor in diabetes were higher than that in IFG.

Abstract
We aimed at updating the prevalence of impaired fasting glucose (IFG) and of undiagnosed (UD) and diagnosed diabetes (DD) among the Sardinian population. The survey was carried out from 2002 to 2005 on 4.737 subjects aged 20-80+ years. IFG was diagnosed when blood glucose was 110-125 mg/dl; UD when it was >or=126 mg/dl in the absence of personal history of diabetes; DD when personal history was positive, irrespective of blood glucose value. Prevalence rates (%) were adjusted for age by direct method to the Italian 2001 population. IFG was diagnosed in 11% of the sample (9.88% in females and 12.24% in males); UD was found in 5.65% (5.20 and 6.15%, females and males, respectively), DD in 8.72% (6.74 and 10.05%); and total diabetes (TD), i.e. the sum of UD + DD, was 14.37% (12.93 and 15.07%, females and males, respectively). In Sardinia, in about 5 years there was an increase of IFG (+61.8%), UD (+56.9%), DD (+55.7%), and TD (+57.9%). Thus Sardinia participates in the worldwide increase in prevalence of diabetes and its microvascular, macrovascular, and socioeconomic consequences.

Abstract
BACKGROUND AND AIM Several working definitions of metabolic syndrome have been proposed for clinical use. However, individuals can be discordantly classified as having or not having metabolic syndrome depending on the choice of one or another definition. This study compared the cardiovascular risk profile of subjects concordantly and discordantly diagnosed by the criteria of the National Cholesterol Education Program (NCEP) and the criteria of the International Diabetes Federation (IDF). METHODS AND RESULTS Nine hundred and twenty-nine non-diabetic adult subjects belonging to a cross-sectional population-based study in Gran Canaria island (Spain) were assessed. Participants completed a questionnaire and underwent physical examination, fasting blood analyses, and a standardized oral glucose tolerance test. Two hundred and four subjects (22%) had metabolic syndrome according to both definitions, 31 (3.3%) only by the IDF criteria, and 5 (0.5%) only by the NCEP criteria. Participants fulfilling both proposals showed more adverse age and sex-adjusted measures of BMI, waist, HDL cholesterol, triglycerides, post-load glucose, HOMA-IR and plasminogen inhibitor activator-1 (PAI-1) than individuals exclusively satisfying the IDF criteria. Moreover, in contrast to subjects meeting both criteria, those that fulfilled only the IDF criteria had levels of BMI, waist, total and HDL cholesterol, post-load glucose, glycated HbA1c, C-reactive protein, PAI-1 and fibrinogen not significantly different from those observed in subjects without metabolic syndrome. CONCLUSION The IDF definition identifies a surplus of individuals whose cardiovascular risk profile, particularly regarding to some non-traditional cardiovascular risk factors, is less adverse than that observed in subjects also diagnosed by the NCEP definition.

Abstract
INTRODUCTION The aim of this study was to analyze differences between patients aged 80 years or less and those aged more than 80 years old a hospital series of ischemic stroke. MATERIAL AND METHODS We performed a retrospective review of all patients with ischemic stroke or transient ischemic attack requiring admission to the Neurology Service of the Dr. Negrín University Hospital of Gran Canaria (Spain) between January 1, 2004 and December 31, 2006. Data were gathered on hypertension, diabetes mellitus (DM), hyperlipidemia, ischemic cardiopathy (IC), atrial fibrillation (AF), the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, as well as the National Institutes of Health (NIH) scale and the modified Rankin scale (mRS) at discharge. RESULTS A total of 850 patients were included. Age was >80 years in 106 (12.4%) and was <80 years in 744 (87.6%). In the group aged>80 years, 43.4% were men and 56.6% were women (64.1% men and 35.9% women in the group aged<80 years). Hypertension was present in 81.1% of patients aged>80 years (68.1% in those aged<80 years); previous DM was found in 29.2% (39.3% in the group aged<80 years); hyperlipidemia was present in 26.4% (40.2% in the group aged<80); IC was found in 16.9% (15.8% in the group aged<80); AF was found in 40% (20.9% in the group aged<80 years). In the group of patients aged>80 years, 23.6% had atherothrombotic stroke (19.3% in those aged<80 years); 38.7% were cardioembolic (19.3% in the group aged<80 years); 10.4% were lacunar (22.6% in the group aged<80 years); and 24.5% was of undetermined origin (28.6% in the group aged<80 years). The mRS at discharge was <or=2 in 73.8% of patients aged<80 years and in 55.7% of those aged>80 years. CONCLUSIONS Ischemic stroke in patients over 80 years old leads to certain differences in relation to risk factors, stroke etiology and stroke severity.

Abstract
BACKGROUND AND AIM This study was aimed to identify additional components of metabolic syndrome from a set of cardiovascular risk markers. METHODS AND RESULTS The homeostasis model assessment of insulin resistance (HOMA-IR), C-reactive protein, fibrinogen, plasminogen activator inhibitor-1 (PAI-1), von Willebrand factor, homocysteine, Haemoglobin A1c (HbA1c), and lipoprotein(a) were assessed in a population-based sample of 902 nondiabetic adult subjects. Those biomarkers that were associated with metabolic syndrome were evaluated by multiple regression analysis, along with other traditional cardiovascular risk factors. Confirmatory factor analysis (CFA) was used to test the hypothesis that both the established components of metabolic syndrome and the novel variables identified by the regression analysis were associated with a single underlying factor. HOMA-IR, PAI-1 and HbA1c were the only biomarkers independently related to metabolic syndrome. CFA validated a one-factor model that included these variables. Moreover, the indices of goodness of fit were better for this expanded model than those obtained for a previously validated one-factor model that was restricted to the conventional elements of the syndrome. CONCLUSIONS These findings show that PAI-1 and HbA1c are singularly linked to metabolic syndrome. Their elevation is presumably another manifestation of the same pathophysiological mechanism that underlies the recognized traits of the syndrome.

Abstract
OBJECTIVE The objective of the study was to determine the prevalence of diagnosed and undiagnosed diabetes, pre-diabetes and to identify the associated risk factors in the sample of adult Qatari population. DESIGN This was a cross-sectional study. SETTING The survey was carried out in urban and semi-urban primary health care centers. SUBJECTS AND METHODS The survey was conducted from January 2007 to July 2008 among Qatari nationals above 20 years of age. Of the 1434 subjects who were approached to participate in the study, 1117 (77.9%) gave their consent. Face to face interviews were conducted using a structured questionnaire followed by laboratory tests. DM was defined according to the WHO expert group. Pre diabetes status was based on the presence of impaired fasting glucose or impaired glucose tolerance. RESULTS The overall prevalence of diabetes mellitus among adult Qatari population was high (16.7%) with diagnosed DM (10.7%) and newly diagnosed DM (5.9%). The impaired glucose tolerance (IGT) was diagnosed in 12.5%, while impaired fasting glucose was in 1.3% with a total of (13.8%). The proportion of DM was higher in Qatari women (53.2%) than in Qatari men (46.8%) and it peaked in the age group 40-49 years (31.2%). The age-specific prevalence of total DM and IGT increased with age. Risk factors were significantly higher in diabetic adult Qatari population: central obesity (p<0.001), hypertension (p<0.001), triglyceride (p<0.001), HDL (p=0.003), metabolic syndrome (p<0.001), heart diseases (p<0.001). Smoking habits and family history of DM were the major contributors for diabetes disease. The central obesity was associated with higher prevalence of DM and IFG among Qatari men and women. CONCLUSION The present study has found a moderately high prevalence of diabetes mellitus in the adult Qatari population. High proportion of pre-diabetes in Qatari adults will increase the prevalence of DM in the next few years. Smoking habits and family history of DM were the major contributors for DM. Early diagnosis of DM is of major importance to reduce the risk of these diabetes-related conditions.

Abstract
OBJECTIVE To characterize the cardiovascular risk profile of subjects with high and normal-high concentrations of serum TSH in a sample of adult Spanish subjects from the island of Gran Canaria. DESIGN Cross-sectional population-based study. SUBJECTS After excluding 28 individuals on current treatment with levothyroxine and 9 others with TSH levels below the range of normality (0.3-4.9 mU/l), 704 randomly selected subjects (412 women; age range: 30-82 yr) belonging to the Telde Study were assessed. MEASUREMENTS Participants underwent physical examination and fasting blood analyses to determinate TSH, serum lipids, homocysteine, fibrinogen, von Willebrand factor, plasminogen activator inhibitor- 1, C-reactive protein, and insulin. RESULTS Twenty-nine participants had serum TSH concentrations above the normal range of normality. Among all the studied variables, only female sex and diastolic blood pressure were significantly associated with TSH levels > or =5 mU/l in a multivariate logistic regression analysis. If the upper normal limit of TSH was reduced up to 2.4 mU/l, an additional group of 106 subjects would be considered to have elevated TSH levels. A serum TSH > or =2.5 mU/l was positive and independently associated with female sex, body mass index, total cholesterol, and homocysteine, and negatively associated with smoking. CONCLUSIONS Although the impact of serum TSH levels on cardiovascular risk cannot be established from these findings, TSH values within the upper part of the usually accepted normal range were demonstrated to be associated with well-recognized risk factors for cardiovascular disease.

Abstract
BACKGROUND Microalbuminuria was originally established as a predictor of renal failure and an independent risk factor for cardiovascular disease in patients with diabetes mellitus as well as in general population. The aim of our study is to assess the relationship between microalbuminuria and the other risk factors in diabetics and their prevalence. METHODS Sixty five patients, 22 men and 43 women with mean age 58.6+/-10.09, with type 2 diabetes, were hospitalized in the Department of Internal Medicine in the University Hospital Center "Mother Teresa" in Tirana, Albania, between March 2007 and February 2008. These patients with a mean duration of diabetes 6.09+/-5.41 were divided in two groups: with (Group A: 24 patients) and without (Group B: 41 patients) microalbuminuria and each group was evaluated for left ventricular mass index (LVMI), body mass index (BMI), glycosylated hemoglobin (HbA1C), lipid profile and intima media thickness (IMT). RESULTS The prevalence of microalbuminuria in our study was 32.3%. The prevalence of microalbuminuria in males was 37.5 and in females 62.5%. The microalbuminuric patients were older ( 59.71+/-9.87 vs 57.07+/-10.32) and had a longer duration of diabetes (7.74+/-5.74 vs 4.45+/-5.08) compared with normoalbuminuric patients (p=0.01). The Group A had significantly higher LVMI compared with Group B ( p=0.02). The prevalence of obesity (BMI>30 kg/m2) in our sample was 44.6%. In Group A the mean BMI (30.13+/-4.98) was significantly higher compared with Group B (28.00+/-3.72, p=0.04). Diabetic retinopathy was more frequent in Group A compared with Group B ( 33.3% vs 14.6%, p=0.05). The mean value of IMT was higher in Group A compared with Group B (1.28+/-0.35 vs 1.09+/-0.28, p=0.03). CONCLUSION In patients with type 2 diabetes and microalbuminuria LVMI, IMT, BMI, duration of diabetes was significantly higher compared with patients with type 2 diabetes and normoalbuminuria.

Abstract
OBJECTIVE The purpose of this study was to determine the prevalence of diabetes, impaired glucose tolerance (IGT), impaired fasting glycemia (IFG), and associated risk factors in a rural South African black community. RESEARCH DESIGN AND METHODS This was a cross-sectional survey conducted by random cluster sampling of adults aged >15 years. Participants had a 75-g oral glucose tolerance test using the 1998 World Health Organization criteria for disorders of glycemia. RESULTS Of 1,300 subjects selected, 1,025 subjects (815 women) participated (response rate 78.9%). The overall age-adjusted prevalence of diabetes was 3.9%, IGT 4.8%, and IFG 1.5%. The prevalence was similar in men and women for diabetes (men 3.5%; women 3.9%) and IGT (men 4.6%; women 4.7%) but higher in men for IFG (men 4.0%; women 0.8%). The prevalence of diabetes and IGT increased with age both in men and women, with peak prevalence in the 55- to 64-year age-group for diabetes and in the >or=65-year age-group for IGT. Of the cases of diabetes, 84.8% were discovered during the survey. In multivariate analysis, the significant independent risk factors associated with diabetes included family history (odds ratio 3.5), alcohol ingestion (2.8), waist circumference (1.1), systolic blood pressure (1.0), serum triglycerides (2.3), and total cholesterol (1.8); hip circumference was protective (0.9). CONCLUSIONS There is a moderate prevalence of diabetes and a high prevalence of total disorders of glycemia, which suggests that this community, unlike other rural communities in Africa, is well into an epidemic of glucose intolerance. There is a low proportion of known diabetes and a significant association with potentially modifiable risk factors.

Abstract
There is currently no consensus regarding the optimal protocol for measurement of waist circumference (WC), and no scientific rationale is provided for any of the WC protocols recommended by leading health authorities. A panel of experts conducted a systematic review of 120 studies (236 samples) to determine whether measurement protocol influenced the relationship of WC with morbidity of cardiovascular disease (CVD) and diabetes and with mortality from all causes and from CVD. Statistically significant associations with WC were reported for 65% (152) of the samples across all outcomes combined. Common WC protocols performed measurement at the minimal waist (33%), midpoint (26%) and umbilicus (27%). Non-significant associations were reported for 27% (64) of the samples. Most of these protocols measured WC at the midpoint (36%), umbilicus (28%) or minimal waist (25%). Significant associations were observed for 17 of the remaining 20 samples, but these were not significant when adjustment was made for covariates. For these samples, the most common WC protocols were the midpoint (35%) and umbilicus (30%). Similar patterns of association between the outcomes and all WC protocols were observed across sample size, sex, age, race and ethnicity. Our findings suggest that WC measurement protocol has no substantial influence on the association between WC, all-cause and CVD mortality, CVD and diabetes.

Abstract
Type 2 diabetes has been catalogued as the epidemic of the 21st Century, both because of its increasing magnitude and its impact on cardiovascular disease, the leading cause of death in developed countries. This review analyses the evolution of the prevalence of diabetes in Spain over recent years, based on various cross-sectional studies. This study shows that previous estimates have been surpassed, with 10-15% of Spanish adults estimated to have diabetes. Factors influencing this phenomenon include the change in diagnostic criteria, population aging, a lower mortality among persons with diabetes or a true increase in the incidence.

Abstract
OBJECTIVE The aim of this study was to define the incidence of type 2 diabetes in a low-risk Caucasian population in northern Spain and its association with various risk factors. RESEARCH DESIGN AND METHODS The Asturias Study is a prospective, population-based survey of diabetes and cardiovascular risk factors. The baseline examination was carried out during 1998-1999 when 1,034 individuals, aged 30-75 years, were randomly selected to determine the prevalence of type 2 diabetes and pre-diabetes in the Principality of Asturias (northern Spain). In 2004-2005, these same subjects were invited for a follow-up examination; 700 participated. This study includes only those individuals who did not have diabetes at baseline. We used the World Health Organization 1999 criteria to classify glucose metabolism at both baseline and follow-up. RESULTS The incidence of diabetes adjusted for the age and sex structure of Asturias was 10.8 cases/1,000 person-years (95% CI 8.1-14.8). The incidence rates were 5 cases/1,000 person-years in individuals with normoglycemia, 21 cases/1,000 person-years in individuals with isolated impaired glucose tolerance (IGT), 34.7 cases/1,000 person-years in individuals with isolated impaired fasting glucose (IFG), and 95.2 cases/1,000 person-years in individuals with combined IFG-IGT. Stepwise multiple logistic regression analysis showed that, together with fasting plasma glucose (FPG) and 2-h plasma glucose, which were the strongest predictors of diabetes, triglycerides and BMI were also independently associated with progression to diabetes. CONCLUSIONS In this 6-year prospective population-based study, we found an incidence of type 2 diabetes of 10.8 cases/1,000 person-years. Both FPG and 2-h plasma glucose were strongly predictive of diabetes, and their effect was additive.

Abstract
To evaluate the level and factors affecting control of diabetes and cardiovascular risk factors in type 2 diabetes (TYPE 2 DM) patients. Multicentre cross-sectional study: a sample of 430 primary care practices across Spain selected 1907 type 2 diabetic patients. The first five consecutive ambulatory patients with TYPE 2 DM were eligible for the inclusion into the survey. Patients were free of known cardiovascular disease (CVD). Control criteria were defined based on 2002 American Diabetes Association (ADA) clinical practice recommendations. A total of 1907 patients (51% women) aged 63 +/- 9 years. Smoking prevalence was 22.6%, 50.6% had levels of A1c < 7%. Mean blood pressure (BP) was 148 +/- 17/86 +/- 10 mmHg. Only 7.8% have achieved the target of BP < 130/80 mmHg. Among the 1180 patients (65%) treated for hypertension, this target was attained in only 4.4% of patients. A measurement for low-density lipoprotein (LDL) cholesterol was available in 1669 patients (88%). Only 5.9% of patients achieved the target of LDL < 100 mg/dl. Among the 638 patients (41.6%) on drug treatment for dyslipidaemia, this target was attained in only 5.6% of patients. Among type 2 diabetic patients in Spain the prevalence of cardiovascular risk factors is high. Control of glycaemia, smoking, BP and LDL are far from optimal despite the widespread use of guidelines for the management of diabetes and CVD. The application of published recommendations needs to be reinforced.
