New diagnostic criteria for diabetes mellitus proposed by the American Diabetes Association in 1997 and the World Heath Organization Consultation Report in 1998 recommend lowering of the fasting plasma glucose (FPG) to 7.0 mmol/L. This change in the diagnostic FPG cut-off point was based on the results of well-documented epidemiological studies showing that increased risk of microangiopathy starts at values closer to 7.0 than 7.8 mmol/L used in the past. To facilitate the diagnosis, ADA Expert Committee recommends using FPG as the main diagnostic tool and eliminating OGTT from routine clinical practice. In contrast to ADA, WHO Consultation Group strongly recommended keeping OGTT in routine use. Due to the inconvenience, poor reproducibility, non-physiological character and labour-intensiveness of OGTT, an alternative test has been sought. The aim of this study was to determine whether fasting capillary glucose (FCG) along with fructosamine and glycated haemoglobin (HbA(1c)) perform better for the detection of glucose tolerance abnormalities than FCG alone. OGTT was performed in 1528 patients. Serum fructosamine was determined in 480 and glycated haemoglobin in 234 of these patients. To assess the value of FCG, fructosamine and glycated haemoglobin in predicting post-load glycaemia and detecting glucose tolerance abnormalities, multiple linear regression analysis and Receiver Operating Characteristics analysis were done. Fructosamine correlated stronger with 2h-postload glucose concentrations than with fasting glucose. HbA(1c) correlated stronger with FCG than with 2h-postload glucose. Combined use of fructosamine and FCG predicted 2h-postload glucose better than combined use of FCG and HbA(1c). Receiver Operating Characteristics curve analysis showed that FCG was the best criterion in discriminating diabetes. Combined use of FCG and fructosamine slightly improved the ability to discriminate glucose tolerance abnormalities from normal glucose tolerance. The following conclusions were drawn: (1) FCG is the most effective predictor of 2h-postload glucose and the best criterion for discriminating diabetes and other glucose tolerance abnormalities from normal glucose tolerance. (2) Because of the limited sensitivity and specificity of fasting glucose, fructosamine and glycated haemoglobin tests, OGTT is irreplaceable in the identification of patients with glucose tolerance abnormalities. Nevertheless, fructosamine is a potentially useful post-load glycaemia index.

The Diabetes In Pregnancy Study group India (DIPSI) is reporting practice guidelines for GDM in the Indian environment. Due to high prevalence, screening is essential for all Indian pregnant women. DIPSI recommends that as a pregnant woman walks into the antenatal clinic in the fasting state, she has to be given a 75g oral glucose load and at 2 hrs a venous blood sample is collected for estimating plasma glucose. This one step procedure of challenging women with 75 gm glucose and diagnosing GDM is simple, economical and feasible. Screening is recommended between 24 and 28 weeks of gestation and the diagnostic criteria of ADA are applicable. A team approach is ideal for managing women with GDM. The team would usually comprise an obstetrician, diabetes physician, a diabetes educator, dietitian, midwife and pediatrician. Intensive monitoring, diet and insulin is the corner stone of GDM management. Oral agents or analogues though used are still controversial. Until there is evidence to absolutely prove that ignoring maternal hyperglycemia when the fetal growth patterns appear normal on the ultrasonogram, it is prudent to achieve and maintain normoglycemia in every pregnancy complicated by gestational diabetes. The maternal health and fetal outcome depends upon the care by the committed team of diabetologists, obstetricians and neonatologists. A short term intensive care gives a long term pay off in the primary prevention of obesity, IGT and diabetes in the offspring, as the preventive medicine starts before birth.

The incidence and prevalence of diabetes have reached epidemic proportions worldwide. The reasons for the pandemic are the sharp rise in obesity, decline in physical activity and the increase in life expectancy. There are some 400,000 people with diagnosed diabetes in Israel and they are at a markedly increased risk for cardiovascular disease, blindness, end-stage renal disease and lower limb amputation. To effectively lower this significantly increased burden of disease, a comprehensive multidisciplinary approach to chronic disease management is required. To facilitate such an approach, the Israel Diabetes Association published a guideline for the diagnosis, prevention and treatment of diabetes. The guideline, based on the ADA (American Diabetes Association) and IDF (International Diabetes Federation) guidelines, was approved by other national professional societies including hypertension, family practice, obesity, nephrology, atherosclerosis and internal medicine. The guidelines highlight the metabolic syndrome and prediabetic states, interventions for the prevention of diabetes, the new definitions of diabetes and impaired glucose metabolism and the newly defined targets for glucose, lipid, cholesterol and blood pressure control. In addition, the recommendations for periodic review and screening for complications are summarized. The need for patient education and empowerment are emphasized as is the need for the development and implementation of unique tools including computerized treatment flow-charts, prompts and quality measures, for the long term management of a complex metabolic disease.

This study examines relationships between patient reported outcomes (PROs) and clinical outcomes in Type 2 diabetes mellitus (T2DM). Patients at the outpatient clinics of a university hospital completed measures of generic health status (SF-12), diabetes-specific quality of life (Audit of Diabetes Dependent Quality of Life - ADDQoL), and depressive symptoms (Center for Epidemiologic Studies Depression - CES-D). Patient reported data were merged with a retrospective collection of clinical and utilization data, including HbA1C, from electronic medical records. A Charlson comorbidity score, diabetes complications score, BMI, and total number of ER and hospital visits were calculated. Usable response rate was 44.3% (n = 385). Patients were dichotomized into glycemic control levels based on the ADA recommended A1C level < 7.0, vs. >or= 7.0. The ADDQoL, PCS-12, and MCS-12 scores were separately examined as dependent variables using hierarchical regression models, with glycemic control as the primary explanatory variable, and controlling for demographics and clinical variables including comorbidities and complications. Glycemic control was not a significant predictor in any regression model. Obesity was a significant predictor leading to poorer PCS-12 and MCS-12 scores, while depressive symptoms significantly resulted in lower PCS-12, MCS-12 and ADDQoL scores. These and other factors related to self-management behaviors may contribute to a greater understanding of how to intervene with patients with T2DM. The use of such PROs alongside biomedical measures such as A1C is recommended.

Aspirin is currently recommended by ADA (American Diabetes Association) for the diabetic patients over 40 years of age and without cardiovascular disease. This recommendation is at odds with drug approval for aspirin. The main explanation is the absence of appropriate trials assessing the usefulness of aspirin in such patients. Two assumptions, central to these guidelines are that diabetes is a coronary risk equivalent, and that aspirin benefit/risk ratio is similar in diabetic patients than in coronary disease patients. Unfortunately, vascular risk level is variable in diabetic patients. Patients with new onset diabetes have lower cardiovascular risk than patients with established cardiovascular disease. Smoking habits markedly increase the risk. Benefits may be lower in diabetic patients since aspirin resistance is common in these patients. Haemorrhagic risk may be higher since diabetes is a risk factor for haemorrhagic stroke. Awaiting trial evidence, aspirin therapy should be considered in diabetic patients with a very high risk, such as smokers, patients with long diabetes duration, or atherosclerotic plaques at echography.

The objective of the present study was to examine the association between a polymorphism of the aldehyde dehydrogenase 2 (ALDH2) gene and lacunar infarcts of the brain. We conducted a population-based, cross-sectional study on residents from two age groups (61- and 72-year olds). A total of 376 subjects participated in the study, which included brain magnetic resonance image and genetic analysis of the ALDH2 gene. Of the 61- and 72-year-old subjects, 46.4% and 64.3%, respectively, had one or more lacunar infarcts. The average number of infarcts also increased from 2.0 to 2.8 in men and from 2.3 to 3.5 in women. No significant association between the ALDH2 genotype and the presence of lacunar infarction (> or =1) was found. However, in subjects with lacunar infarction, the genotype of ALDH2 *1/*1 was associated with a larger number of the lesion ['single' versus 'multiple' odds ratio (OR) 3.73, 95%CI: 1.43-9.74] in men. The OR was comparable even after adjusting for alcohol consumption, tobacco habits, age, hypertension, hypercholesterolemia, and diabetes mellitus (DM) (OR 3.88; 95% CI: 1.10-13.66). In women, there was no significant association between the ALDH2 genotypes and lacunar infarcts. The present study revealed that the ALDH2 *1/*1 genotype was significantly associated with the prevalence of multiple lacunar infarcts in Japanese men.

The epidemic of type 2 diabetes in the latter part of the 20th and early 21st centuries and the recognition that achieving specific glycemic goals can substantially reduce morbidity, have made effective treatment of hyperglycemia a top priority. In addition, strict control of the multiple, classical and emergent cardiovascular risk factors are also important. Diabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. The development of new classes of blood glucose-lowering medications such as glitazones to supplement the classical therapies such as sulfonylureas and metformin has increased oral treatment options for type 2 diabetes. Combined therapy of two oral agents is the essential axis of type 2 diabetic patients. Early insulin therapy in combined therapy is presently an option according to ADA-2007 Standards.

Sufficient evidence exists in relation to the association in clinical practice between disorders in the metabolism of glucose, lipoproteins, insulin action, arterial hypertension and centrally-distributed obesity. This association is named Metabolic Syndrome. Despite the existence thereof had been questioned by the ADA and EASD, it is a useful tool affording the possibility of identifying individuals at high risk of developing cardiovascular disease. Metabolic syndrome and/or its individual components are associated with a high incidence rate of cardiovascular disease. Obesity and a sedentary lifestyle are underlying risk factors along this syndrome's pathway to disease, changes in living habits therefore being a first-line intervention in the prevention and treatment of insulin resistance, hyperglycemia, aterogenic dyslipemia and arterial hypertension. Weight loss and exercise are the keys to the overall plan, one of the most important non-pharmacological cardiovascular risk reduction strategies however still being diet. Epidemiological studies have found a high intake of simple sugars, of foods having a glycemic index and of diets with a high glycemic load to be associated to insulin resistance, type II diabetes mellitus, hypertriglyceridemia and low HDL-cholesterol figures. Los saturated fat intake in favor of polyunsaturated and monounsaturated fatty acids has been implied in a reduction of the incidence of type II diabetes mellitus and dyslipemia, although the debate is ongoing. Unrefined grain fiber in the diet has been beneficial in reducing the risk of diabetes. Among the diet patterns, the Mediterranean diet has been related to a lower incidence of diabetes and a reduction in the risk of death. Studies for intervention in the prevention of type II diabetes have suggested low-fat diets (reducing saturated and trans-fats), with a high degree of fiber and low glycemic index. Clinical trials have shown diets with small amounts of carbohydrates, low glycemic index and the Mediterranean and DASH diets to be beneficial in reducing aterogenic dyslipemia. There is currently no good evidence for choosing diets with restricted carbohydrates. On the other hand, different guides recommend low-calorie diets with a low content in saturated fats, trans-fats, cholesterol and sugars in favor the eating fruits, green vegetables, unrefined grains and fish.

The prevalence of obesity has been increasing dramatically in the last decades; the major metabolic complication of obesity is insulin resistance and type-2 diabetes because there are pathogenetic mechanisms linking obesity and type-2 diabetes. Diabetes is also rapidly increasing worldwide; such a description of the key stages in the evolution of type-2 diabetes may be of great interest for implementing antidiabetes treatment. In recent times, type-2 diabetes therapy has been based on drugs, which improve insulin sensibility or stimulate insulin secretion or slow down glucose absorption. Recently, an ADA and EASD consensus has been released to develop a common approach for the management of hyperglycaemia in adults. The development of new classes of blood-glucose-lowering medications to supplement the older therapies, such as lifestyle-directed interventions, insulin, sulfonylureas, and metformin, has increased the different possible options for the treatment of type-2 diabetes. Therapeutic approaches aiming to potentiate the biological effects of incretins include degradation-resistant GLP-1 receptor agonists (incretin mimetics), and inhibitors of dipeptidyl peptidase-IV (DPP-IV) activity (incretin enhancers) will be very useful to slow down type-2 diabetes progression. Weight-loss interventions, such as a hypocaloric diet and physical exercise, in addition to agents such as orlistat, sibutramine and cannabinoid receptor antagonists, may have favourable effects upon fat storage, nutrient metabolism and ultimately glucose tolerance or type-2 diabetes. When the therapeutic target is not achieved, insulin with metformin could be suggested, but is this approach the ideal one for all patients? Perhaps it is possible to delay the initiation of insulin therapy, therefore, the actual and future therapeutical options are considered in the present review.

Metformin has been used successfully since the 1950s as first line pharmacotherapy to treat people with type 2 diabetes. It is a biguanide that decreases blood glucose concentration by mechanisms different from those of insulin secretagogues, such as sulphonylureas, or exogenous insulin therapy. Metformin lowers, rather than increases, fasting plasma insulin concentrations and acts by enhancing insulin sensitivity, inducing greater peripheral uptake of glucose, and decreasing hepatic glucose output. By reducing hepatic glucose output it lowers blood glucose and insulin levels with minimal risk of hypoglycaemia, and when used as monotherapy can lower HbAlc by around 1.5%. It is usually well tolerated, the most common side effects being gastrointestinal. Of particular value is that the improved glucose control seen with metformin is achieved without weight gain. Concerns that it may increase the risk of lactic acidosis have largely been allayed with recent studies suggesting less than one case per 100,000 treated patients. The UK Prospective Diabetes Study (UKPDS) demonstrated a substantial beneficial effect of metformin therapy on cardiovascular disease (CVD) outcomes, with a 36% relative risk reduction in all cause mortality and a 39% relative risk reduction in myocardial infarction . The first ever joint ADA (American Diabetes Association) and EASD (European Association for the Study of Diabetes) consensus guidelines on the management of hyperglycaemia in type 2 diabetes state explicitly that metformin should be used as first-line foundation therapy, in addition to lifestyle interventions.
