Careful selection of bariatric patients is critical for successful outcomes. In 1991, the NIH first established patient selection guidelines; however, some surgeons operate on individuals outside of these criteria, i.e., extreme age groups. We developed appropriateness criteria for the spectrum of patient characteristics including age, BMI, and severity of eight obesity-related comorbidities. Candidate criteria were developed using combinations of patient characteristics including BMI: > or =40 kg/m(2), 35-39, 32-34, 30-31, <30; age: 12-18, 19-55, 56-64, 65+ years old; and comorbidities: prediabetes, diabetes, hypertension, dyslipidemia, sleep apnea, venous stasis disease, chronic joint pain, and gastroesophageal reflux (plus severity level). Criteria were formally validated on their appropriateness of whether the benefits of surgery clearly outweighed the risks, by an expert panel using the RAND/UCLA modified Delphi method. Nearly all comorbidity severity criteria for patients with BMI > or =40 kg/m(2) or BMI = 35-39 kg/m(2) in intermediate age groups were found to be appropriate for surgery. In contrast, patients in the extreme age categories were considered appropriate surgical candidates under fewer conditions, primarily the more severe comorbidities, such as diabetes and hypertension. For patients with a BMI of 32-34, only the most severe category of diabetes (Hgb A1c >9, on maximal medical therapy), is an appropriate criterion for those aged 19-64, whereas many mild to moderate severity comorbidity categories are "inappropriate." There is overwhelming agreement among the panelists that the current evidence does not support performing bariatric surgery in lower BMI individuals (BMI <32). This is the first development of appropriateness criteria for bariatric surgery that includes severity categories of comorbidities. Only for the most severe degrees of comorbidities were adolescent and elderly patients deemed appropriate for surgery. Patient selection for bariatric procedures should include consideration of both patient age and comorbidity severity.

Microvascular complications are an important cause of morbidity in diabetic patients and can be detected in a significant number of patients at the time of diabetes diagnosis. However, little is known about the alterations in the microvasculature previous to the clinical manifestation of diabetes mellitus type 2. To obtain more insights into the early microvascular deterioration resulting from prediabetes, morphological and functional microvascular parameters were monitored using intravital fluorescence microscopy through a dorsal skin-fold chamber preparation in the uncoupling promotor-driven diphtheria toxin A chain (UCP1/DTA) mice. At the age of 12 weeks, the UCP1/DTA-mice were characterized by impaired glucose tolerance with concurrent unchanged fasting glucose, as well as dyslipidemia, hyperinsulinemia, hypertension and obesity. Prediabetic mice displayed combined hypertriglyceridemia and hypercholesterinemia. Associated with these prediabetic metabolic alterations, we demonstrate that microvascular density showed a dramatic decrease due to a reduction in perfused small vessels. A reduction in vascular density combined with unaltered blood flow in single vessels resulted in impaired tissue perfusion. Endothelial dysfunction with subsequently increased microvascular permeability and leukocyte-endothelium interactions were found. Our results of profound microvascular alterations at stages of normal fasting glucose underline the importance of early screening for prediabetes and associated microvascular complications.

Prediabetes is now considered as a definite entity for increased incidence of cardiovascular disease and a potent risk for progression to type 2 diabetes mellitus. As macrovascular disease is the commonest cause of increased mortality in dysglycaemic individuals (prediabetes and diabetes) by 2-4 times as opposed to normal individuals, clinicians do encounter patients with cardiovascular disease of varying severity regularly. There are increased constellation of other cardiovascular risk factors (hypertension, dyslipidaemia, etc), in prediabetes as compared to normal population. Here a study was carried out among 62 acute coronary syndrome patients who were admitted in a tertiary care hospital in Kolkata to find out the proportion of prediabetes in them. Majority of the patients (54.8%) were in the age group of 45-64 years and were males (77.4%). The study showed 48.4% of all acute coronary syndrome patients were prediabetic and 25% were diabetic. The proportion of impaired fasting glucose and impaired glucose tolerance were 19.4% and 22.6% respectively. So, altogether 72.4% patients were dysglycaemic. Out of all acute coronary syndrome patients, non-ST elevated myocardial infarction group had 50% prediabetic patients, ST elevated myocardial infarction group had 50% prediabetic patients and unstable angina group have 45.8% prediabetic patients. So, all patients of acute coronary syndrome should be screened to detect hyperglycaemia in early stage to prevent further development of diabetes mellitus and also further cardiovascular events.

Condition prior to diabetes is designated as prediabetes. The use of this term is recommended if fasting plasma glucose exceeds normal level but does not reach the characteristic result of real diabetes. Prediabetes is often characterized by combination of visceral obesity, glucose and lipid metabolism disorders and changes in blood pressure. Change of life style is more important in the treatment of prediabetes associated hypertension than in other hypertensive diseases. In this case, metabolically neutral antihypertensive medication is the treatment of choice. The growing obesity epidemic underlines the significance of prediabetes associated hypertension in public health. While 25% of the adult population suffering from this kind of hypertensive disease, the optimal solution has to be found together with patients, physicians and the money lenders of the social security system.

In this article, we estimate national health care resource use and medical costs in 2007 associated with prediabetes (PD), defined as either fasting plasma glucose between 100 and 125 or oral glucose tolerance test between 140 and 200. We use Poisson regression with medical claims for an adult population continuously insured between 2004 and 2006 to analyze patterns of health care resource use by PD status. Combining rate ratios that reflect health care use patterns with national PD prevalence rates from the National Health and Nutrition Examination Survey, we calculate etiological fractions to estimate the portion of national health resource use associated with PD. The findings suggest that PD is associated with statistically higher rates of ambulatory visits for hypertension; endocrine, metabolic, and renal complications; and general medical conditions. PD is associated with a slight increase in visit rates for neurological symptoms, peripheral vascular disease, and cardiovascular disease, but the increase is not statistically significant. There is no indication that PD is associated with an increase in emergency visits and inpatient days. Extrapolating these patterns to the 57 million adults with PD in 2007 suggests that national annual medical costs of PD exceed $25 billion, or an additional $443 for each adult with PD. PD is associated with excessive use of ambulatory services for comorbidities known to be related to diabetes. Our findings strengthen the business case for lifestyle interventions to prevent diabetes by adding additional economic benefits that potentially can be achieved by preventing or delaying PD.

Hypertension can be detected very often in patients with diabetes mellitus. In some cases, hypertension develops as a consequence of diabetic nephropathy. Although diabetic nephropathy may occur both in type 1 and in type 2 diabetes, some differences can be observed in the clinical picture according to the type of diabetes. In the majority of patients with type 2 diabetes or prediabetes, the pathomechanism of hypertension can be explained by the concept of the metabolic syndrome. In order to avoid or decrease target organ damage, the goal of antihypertensive treatment in diabetes mellitus is to be set at <130/80 mmHg. The initial antihypertensive therapy is usually based on the evaluation of the global cardiovascular risk. Apart from modifying nutrition and lifestyle, pharmacological treatment with combination of antihypertensive drugs is generally required in order to achieve treatment goal. Diabetic or antidiabetic properties of antihypertensive drugs and antihypertensive characteristics of some antidiabetic drugs should be considered in the everyday clinical practice.

Worldwide, along with the increasing prevalence of obesity, the number of people with prediabetes is increasing. The diagnostic criteria for prediabetes include impaired fasting glucose, impaired glucose tolerance, and metabolic syndrome. The presence of two or more of these three criteria renders a person at high risk for future diabetes. The treatment goal of prediabetes is to prevent future development of type 2 diabetes and diabetes-related cardiovascular complications. The treatment approach is twofold: glycemic control and control of cardiovascular risk factors, mainly hypertension and hyperlipidemia. Intensive lifestyle modification is the mainstay of treatment in low-risk patients. When lifestyle modification fails and in high-risk patients, medications such as metformin and/or acarbose are recommended. For high-risk patients and those who progress despite intensive lifestyle modification, thiazolidinediones are also recommended. The goals for cardiovascular risk factor control are similar to those for patients with diabetes.

Albuminuria has emerged from being a sign of early kidney disease in diabetes to an independent predictor of cardiovascular risk. Epidemiological studies suggest that microalbuminuria (30-300 mg/d) is present in 5-19% of the general population, in up to 23% of patients with hypertension and in up to 40% of patients with diabetes. Recent data suggest an even higher prevalence in certain patient populations. As it is associated with a variety of important cardiovascular risk factors, including prediabetes, dyslipidemia and the metabolic syndrome, detection of albumin in the urine represents an important diagnostic window for systemic micro- or macrovascular damage. Various studies have demonstrated the predictive value of all levels of albuminuria for future cardiovascular events in patients with diabetes, hypertension or overt cardiovascular disease, as well as in the general population. Annual screening for microalbuminuria is now recommended by international diabetes guidelines for patients with diabetes, and may be appropriate for nondiabetics with risk factors for cardiovascular disease.

The cardiometabolic syndrome has been associated with both chronic kidney disease (CKD) and cardiovascular disease (CVD). Using data from the National Kidney Foundation-Kidney Early Evaluation Program, the authors sought to investigate this association in a targeted CKD cohort. A total of 26,992 patients met eligibility criteria including age 18 years and older, diabetes, hypertension, or family history of CKD, diabetes, or hypertension and excluded those taking renal replacement therapy. Individuals were identified by Third Report of the National Cholesterol Education Program Adult Treatment Panel (NCEP-ATP III) criteria (dysglycemia, hypertension, and dyslipidemia) and World Health Organization criteria (obesity and proteinuria). Univariate and multivariate analyses were used to evaluate increasing components of the cardiometabolic syndrome, CKD, and CVD. On multivariate analysis there was a graded relationship between increasing components with an increased prevalence of CKD and CVD. Additionally, there was a graded trend with the stage of dysglycemia (eg, normoglycemia, prediabetes, and overt diabetes) and increasing CKD. However, there was only an increased prevalence of CVD observed in the clinically diabetic group. This trend was also observed with increasing serum glucose levels and an increasing percent of CVD and CKD up to 160 mg/dL. However, prevalent CVD increased at >140 mg/dL and prevalent CKD at >180 mg/dL. Therefore, data support that increasing metabolic components and dysglycemia are strongly associated with an increased prevalence of CKD and CVD.

Recent studies have introduced serum uric acid (UA) as a potential risk factor for developing diabetes, hypertension, stroke, and cardiovascular diseases. The value of elevated levels of UA in serum as a risk factor for diabetes development is still under scrutiny. Recent data suggest that clearance of UA is being reduced with increase in insulin resistance and UA as a marker of prediabetes period. However, conflicting data related to UA in serum of patients with Type 2 diabetes prompted us to study the urine/serum ratio of UA levels (USRUA) in these patients and healthy controls. All subjects included in the study were free of evidence of hepatitis B or C viral infection or active liver and kidney damage. Patients receiving drugs known to influence UA levels were also excluded from this study. Analysis of glucose and uric acid were performed on Dade Behring analyzer using standard IFCC protocols. Interestingly, our data demonstrated about 2.5 fold higher USRUA values in diabetic patients as compared to control subjects. Furthermore, there was a trend of correlation of USRUA value with the blood glucose levels in diabetic patients, which was more prominent in diabetic men than in women. With aging, levels of uric acid increased in serum of diabetic patients, and this effect was also more profound in male than in female diabetics. In conclusion, this study showed significantly elevated USRUA levels in patients with Type 2 diabetes, a negative USRUA correlation with the blood glucose levels in diabetic patients, and an effect of sex and age on the uric acid levels. Since literature data suggest a strong genetic effect on UA levels, it would be pertinent to perform further, possibly genetic studies, in order to clarify gender and ethnic differences in UA concentrations.
