Introduction: Bruxism is a parafunctional activity with unclear etiology. Psychological stress might be involved. The aim of this observational study was to compare the prevalence of bruxism between cardiopathic patients and non-cardiopathic patients. Subjects and methods: The population study was based on 120 patients divided in 2 groups: Cardiopathic patients (Test-group; n=60) and Non-Cardiopathic patients (Control-group; n=60). All the patients included in the study were screened for bruxism with the “tooth wear Index” (TWI). The TWI value was supposed to be higher or equal to 2 for the 50% of the teeth to define the diagnosis of bruxism. The prevalence of bruxism was calculated and compared in both groups. Results: In the Test-group, 55 out of 60 cardiopathic patients were bruxist, with a prevalence of 91,67%. In the Control-group, 17 out of 60 non cardiopathic patients were bruxist with a prevalence of 28,33%. (Table-3) Conclusion: Cardiopathic patients showed a higher prevalence of bruxism than non-cardiopathic patients. Further prospective studies are needed to evaluate the relation occurring between the two conditions.

AIM: Dyslipidemia plays a crucial role in the development of cardiovascular diseases. A correct lifestyle behaviour based on a balanced diet and moderate physical exercise is the first-line approach, however drug treatment (chiefly statins and/or ezetimibe) may be often needed. Among dietary supplements, so-called "nutraceuticals" are nowadays continuously proposed and frequently employed. In this paper we report our experience with a nutraceutical product largely utilized in Italy (as well as in Mediterranean area) (ARMOLIPID PLUS), based on red yeast rice, berberine, policosanol and some antioxidants, for the treatment of dyslipidemic people. MATERIAL AND METHODS: In this open-label trial we treated with this nutraceutical 37 dyslipidemic nondiabetics and 15 dyslipidemic type 2 diabetics for 12 months, monitoring serum lipids, fasting glucose, glycated hemoglobin, blood pressure, and performing also anthropometric measurements including skinfold thickness. RESULTS: Both in dyslipidemic and diabetic patients we observed a great (about 80-100 mg/dL) parallel decrease of total- and non-HDL Cholesterol, not justified by LDL-Ch decrease (about 37 mg/dL). Furthermore, while body weight and body mass index were not affected significantly by treatment, suprailiac skinfolds (around 6 cm) and total skinfold sum (10 cm) were heavily reduced by the nutraceutical in both groups of patients. CONCLUSION: The present paper confirms that this nutraceutical, due to the synergistic complementary interaction between berberine and red yeast rice, is a reliable option for effective management of dyslipidemia in metabolic disorders with glucolipidic abnormalities.

Aims: The use of Orlistat as an aid for weight loss has increased among obese individuals over recent years. Although the most frequently administered dosage is 120 mg three times daily, data on the metabolic effects of this drug are inconclusive. The primary aim of the present study was to determine the effectiveness of chronic, low-dose Orlistat administration on weight reduction and metabolic profile among individuals who present for weight loss. Methods: We report here results from a three month study at a low-dose (60 mg twice daily) in 15 obese subjects with metabolic syndrome characteristics (hyperglycaemia, dyslipidaemia, hypertension) with no change of diet and physical habits and no other drugs. Results and Conclusion: We observed a significant decrease of weight, BMI, glucose and glycated haemoglobin, diastolic pressure, total cholesterol, LDL cholesterol, non-HDL cholesterol, triglycerides, with a mild significant rise of HDL cholesterol. Of relevance, the decrease of non-HDL fraction was double of that of LDL (13 vs 7%), possibly suggesting effectiveness not only on LDL

Over the past decades, the prevalence of the metabolic syndrome (MetS), a health condition identified by a cluster of risk factors linked to the development of cardiovascular disease, type 2 diabetes mellitus and some types of cancer, has dramatically increased in the world. The rising of MetS incidence and progression appear related to Westernization of dietary habits in the world, with a corresponding increase in the consumption of meat or meat products, snacks, baked desserts and sugar-sweetened beverages not only in the Western countries, but also in the Mediterranean region and among the Eastern populations. Otherwise epidemiological evidence suggests that a high dietary intake of fruits, vegetables, fish and whole grains can improve all the risk factors related to MetS. Particularly adherence to the Mediterranean diet seems to have positive effects on the prevalence and progression of the MetS. In this article we reviewed cohort studies, cross-sectional studies and clinical trials, showing new evidence supporting the beneficial role of adherence to the Mediterranean dietary pattern on the MetS progression. Analysis of the literature suggests that Mediterranean diet should be considered as a healthy and sustainable lifestyle playing a key role in primary and secondary prevention of MetS and its components.

Ottavio Giampietro, Chiara Giampietro, Luca Della Bartola, Maria Chiara Masoni, Elena MatteucciDepartment of Clinical and Experimental Medicine, University of Pisa, Pisa, ItalyBackground: Sitagliptin has been proven to be effective and safe as add-on to insulin in adult patients with type 2 diabetes and absolute insulin deficiency. Recently, it has been suggested to extend the use of dipeptidyl-peptidase-4 inhibitors to type 1 diabetes. The aim of this study was to evaluate and compare the effects of a long-term, fixed-dose combination of sitagliptin and metformin as add-on to insulin on body mass index, fasting plasma glucose, fructosamine, HbA1c, lipids, and daily dose of insulin in both type 1 diabetes and insulin-treated type 2 diabetes.Methods: We recruited 25 patients with type 1 diabetes (mean age 51 ± 10 years, mean disease duration 26 ± 13 years) and 31 insulin-treated type 2 diabetic patients (mean age 66 ± 8 years, mean disease duration 19 ± 9 years), who received sitagliptin with metformin as a fixed-dose combination (50/1000 mg once or twice daily) or sitagliptin (100 mg once daily, if intolerant to metformin) in addition to ongoing insulin therapy for 46 ± 19 weeks and 56 ± 14 weeks, respectively.Results: After 21 ± 9 weeks, patients with type 1 diabetes had a significantly lower body mass index, fasting plasma glucose, fructosamine, HbA1c, and daily insulin requirement. After 49 ± 17 weeks, they maintained their weight loss and total daily insulin dose and showed a significant reduction in low-density lipoprotein cholesterol levels, whereas their HbA1c had returned to baseline values. In patients with type 2 diabetes, long-term treatment remained weight-neutral but had persistent beneficial effects on short-term, intermediate-term, and long-term biomarkers of metabolic control, as well as on low-density lipoprotein cholesterol levels and insulin requirement.Conclusion: Clinical outcomes differed according to type of diabetes in terms of quality and over time. In type 2 diabetes, the combination therapy significantly improved metabolic control and the lipid profile, and decreased insulin requirements, even in the absence of clinically significant weight loss. In type 1 diabetes, the combined therapy only temporarily improved metabolic control, but significantly decreased body weight, low-density lipoprotein cholesterol levels, and insulin requirements.Keywords: dipeptidyl-peptidase-4 inhibitors, drug therapy combination, metformin, synthetic analogs of insulin, diabetes mellitus, type 1, type 2

Vascular oscillation (vasomotion) occurs in the microcirculation and is thought to be a significant contributor to tissue perfusion. Our aim was to assess skin vasomotion (SV) of type 1 diabetic patients (T1D-pts) and its relationship with clinical or laboratory variables of the studied T1D-pts. Forearm endothelial-, sympathetic- and myogenic-dependent SV were assessed basally and after 3 min of forearm ischemia in 40 T1D-pts and 50 healthy controls, by spectral analysis of laser-Doppler (LD) signal at the frequency ranges of 0.009-0.02 Hz, 0.021-0.06 Hz and 0.061-0.2 Hz, respectively. Post-ischemic per cent increase (PI%-increase) in power spectral density (PSD) of skin endothelial- and sympathetic-dependent VS was significantly reduced in T1D-pts compared to controls (p < 0.0005, p < 0.0001, respectively). Linear regression analysis showed a significant positive relationship between PI%-increase of endothelial-dependent SV and heart rate variation during laying-standing test (R = 0.65, p = 0.00001), and a negative relationship between PI%-increase in PSD of skin LD signal 0.009-1.6 Hz spectrum and glycated haemoglobin serum levels (R = 0.44, p = 0.0036) in T1D-pts. These results are consistent with reduced skin endothelial- and sympathetic-dependent stimulated SV and with relationships between some clinical or laboratory variables and SV parameters in the T1D-pts studied.

The new drug class of dipeptidyl peptidase-4 (DPP4) inhibitors has been widely accepted in the daily management of type 2 diabetes since its strategic advantages with regard to body weight, risk of hypoglycaemia, and beta cell survival. We have previously evaluated the theoretical implications of DPP4 inhibition given that the enzyme is involved in regulating biological activity of hormones, neuropeptides, and cytokines. We intend now 1) to provide a critical appraisal of safety and tolerability as they emerged from the available clinical studies, and 2) to establish, if possible, a relation between chemical properties, biological activity, and the observed side effects in vivo.

In diabetic patients glucose, haemoglobin A1c, ketones, lipids, and urinary albumin monitoring allows prevention, early detection, and treatment of diabetes-related acute and chronic complications. The point-of-care testing (PoCT) technology offers convenient aspects, as long as pre-analytical, analytical, and post-analytical errors are minimised. The overview summarises the current state-of-the-art of PoCT in diabetes care.

Redox regulatory system controls normal cellular functions. Controlled changes in redox couples potential serve as components for signal transduction, similarly to the phosphorylation cascade. Cellular redox biology requires both compartimentalisation and communication of redox systems: the thermodynamic disequilibrium of the major redox switches allows rapid and sensitive responses to perturbations in redox environments. The many oxidation states of sulphur are found in numerous sulphur species with distinct functional groups (thiols, disulphides, polysulphides, sulphenic, sulphinic and sulphonic acids, etc.), which participate in a complicated network of sulphur-based redox events. Human diseases such as diabetes mellitus and its cardiovascular complications have been associated with increased production of reactive oxygen species and perturbations of thiol redox homeostasis. The review surveys literature related to some etiopathogenic aspects and therapeutic perspectives. The dual toxic-protective property of sulphydryl-donor molecules in experimental settings proposes the general problem of designing antioxidants for therapeutic use.

Proper cellular function requires the maintenance of mitochondrial membrane potential (MMP) sustained by the electron transport chain. Mitochondrial dysfunction is believed to play a role in the development of diabetes and diabetic complications possibly because of the active generation of free radicals. Since MMP can be investigated in clinical settings using fluorescent probes and living whole blood cells, mitochondrial membrane alterations have been observed in some chronic disorders. We have used the mitochondrial indicator 5,5',6,6'-tetra chloro-1,1',3,3'-tetraethylbenzimidazolyl-carbocyanine iodide (JC-1) in conjunction with flow cytometry to measure the MMP in peripheral blood granulocytes from type 1 diabetes (T1D) families. The intracellular ROS levels and the respiratory burst activity were also measured. Leukocyte MMP was elevated in 20 T1D patients and their 20 non-diabetic siblings compared with 25 healthy subjects without family history of T1D. Fasting plasma glucose was the only correlate of MMP. If confirmed by further observations, the functional implications of mitochondrial hyperpolarisation (probably different among different cells) will require extensive investigation.

Part of the international variation in the gender differences in total mortality remains unexplained. Although a continuous decrease in age-standardised death rates was observed in Italy, the difference between male and female rates became relatively small or even reversed (as the rate for ischaemic heart diseases). We performed an extensive evaluation of cardiovascular risk factors - demographic and clinical characteristics, biochemi- cal parameters, and oxidative biomarkers - in a sample of healthy subjects (94 women and 75 men) from Central Italy and analysed their relationship with the response to ergometer exercise. In addition to a proportion of smokers similar to that observed in men, a clustering of peculiar female cardiovascular risk factors emerged. This included: higher platelet counts, low participation in leisure-time aerobic physical activities, hyper- tensive response to exercise (BMI-dependent, unlike in men), and low fraction of heart rate reserve. Physical inactivity and high serum IL-6 levels were independently predictive of having both chronotropic incompetence and abnormal heart rate recovery.

Nutrition is considered to be one of the key components in the development of most chronic degenerative dis- eases so that medical nutrition therapy has become important in their primary prevention. Food-based dietary guidelines provide the following values: the Lowest Threshold Intake (LTI), the Average Requirement (AR) and the Population Ref- erence Intake (PRI) or Recommended Dietary Allowance (RDA). RDA indicates the quantity of a nutrient that must be present in the food supply if the dietary requirements of most of the population are to be met. Contrary to the established optimistic belief about Mediterranean diet, we have repeatedly documented widespread unhealthy dietary behaviours in adult subjects living in Pisa. The distribution of energy sources was incorrect and fibre consumption did not match general guidelines. Moreover, mild to moderate combined element (calcium) and vitamin (vitamin B1, folates, vitamin D, and vi- tamin E) deficient intakes were observed. The finding of essential nutrient deficiencies in otherwise over-nourished adults prompted us to reconsider the variety and abundance of foods required to guarantee the reference requirements for those substances and which are the historical, environmental, and contingent factors able to prevent the adequacy of food sup- plies in meeting physiological needs.

Perturbations in the redox-based network of cellular regulatory mechanisms have been associated with oxidative-related diseases such as diabetes mellitus. In these situations the redox state of cellular redox systems becomes persistently shifted toward oxidation that may result in a sequence of pathophysiological events. Innate and adaptive immune responses depend on the production of reactive oxygen species and ATP synthesis, which are tightly regulated by the mitochondrial transmembrane potential. Mitochondrial hyperpolarisation is a key mechanism of T-cell life, apoptosis and autoimmunity. The NADPH oxidase of the phagocytic cells of the immune system generates reactive oxygen metabolites during the respiratory burst, but activated B cells also possess NADPH oxidase and reactive oxidants could play regulatory roles in immune function. Cellular thiol levels and the thiol reduction-oxidation process modulate the oxidative metabolism in the cells, transcriptional factor activation of gene expression, lymphocyte proliferation and death. Flow cytometry allows directly characterising and analysing several parameters and functions of intact living cells in a few seconds. Fluorescent lipophilic cations have been used for the measurement of the mitochondrial transmembrane potential. Evaluation of reactive oxygen intermediates generation in neutrophils may be obtained by use of oxidation-sensitive probes. The dye resazurin has been used to quantify mitochondrial activity since considered to act as an intermediate electron acceptor in the electron transport chain between the final reduction of oxygen and cytochrome oxidase. The fluorescence emitted by 5-chloromethyl fluorescein acetate stained cells reflects the total level of free intracellular thiol. In this review we will discuss the possible importance and consequences of evaluating these redox parameters in diabetes pathophysiology. Moreover, we will provide perspectives concerning the varieties of analytical procedures that are capable of measuring them. The advantages and disadvantages of each of these methods are critically discussed particularly in view of their clinical application.

Diabetes mellitus has been associated with a higher risk of exocrine pancreas disorders despite inconsistencies among studies, presumably due to the presence of several (often unmeasured) confounding factors. As a direct consequence of this uncertainty, the relationship between anti-diabetic therapies and pancreatic adverse reactions is difficult to evaluate and remains far from being clarified. Indeed, the on going debate on the safety of incretin-based therapies does not lie in any definite conclusion. Serum level of amylases and lipase reflects the balance between production from different tissues and clearance, but it may be also influenced by numerous molecular, cellular, and systems mechanisms. The present review tries to provide an overview of potential biochemical pathways that may underlie pancreatic hyperenzymemia in health and diabetes mellitus.

Insulin is a life-saving medication for people with type 1 diabetes, but traditional insulin replacement therapy is based on multiple daily subcutaneous injections or continuous subcutaneous pump-regulated infusion. Nonphysiologic delivery of subcutaneous insulin implies a rapid and sustained increase in systemic insulin levels due to the loss of concentration gradient between portal and systemic circulations. In fact, the liver degrades about half of the endogenous insulin secreted by the pancreas into the venous portal system. The reverse insulin distribution has short- and long-term effects on glucose metabolism. Thus, researchers have explored less-invasive administration routes based on innovative pharmaceutical formulations, which preserve hormone stability and ensure the therapeutic effectiveness. This review examines some of the recent proposals from clinical and material chemistry point of view, giving particular attention to patients' (and diabetologists') ideal requirements that organic chemistry could meet.

Objective Oxidative stress is increased in type 1 diabetes families. Since oxidative damage is a mediator of vascular injury and familial predisposition to hypertension increases the risk of hypertension and diabetic nephropathy, we studied blood pressure responses to exercise and cardiovascular risk factors in type 1 diabetes families. Methods Thirty-five type 1 patients, 74 first-degree relatives, and 95 healthy individuals without established coronary heart disease underwent a cycle ergometer test. Examination included medical history, lifestyle questionnaire, body weight, blood pressure, and laboratory tests [fasting plasma glucose and insulin, haemoglobin A 1c (HbA 1c ), plasma lipids, C-reactive protein, fibrinogen, folate, plasma thiols, and albumin excretion rate]. Results Diabetic patients had higher plasma glucose, HbA 1c , folate, and albuminuria, while lower plasma thiols than controls; relatives differed from controls in higher plasma total cholesterol and albuminuria, lower plasma thiols. No patient presented exercised-induced angina. Diabetic patients achieved a higher maximal exercise systolic blood pressure (similar workload); systolic pressure remained high during recovery. Relatives showed higher values of systolic pressure at peak exercise (same workload). The following were associated with an abnormal blood pressure response to exercise: diastolic blood pressure and HbA 1c in the control sample; disease duration and fibrinogen in the diabetic group; plasma low-density lipoprotein (LDL) cholesterol, body mass index (BMI), housework, and plasma thiols among relatives. Conclusion An abnormal blood pressure response to exercise testing has been identified for the first time in asymptomatic normotensive non-diabetic relatives of type 1 diabetics, which was associated with indices of metabolic syndrome and oxidative damage. Moreover, in healthy normotensive non-diabetic control individuals (without a family history of type 1 diabetes), the systolic blood pressure response to exercise was significantly correlated with HbA 1c levels.

Nutritional status and lifestyle can have profound effects on health. To analyse behaviour patterns in population subgroups of public health importance, we compared lifestyle, dietary intake of energy and selected nutrients, and nutritional biomarkers of type 1 diabetes (T1DM) patients and nondiabetic first-degree relatives against control subjects with no family history of T1DM.A cross-sectional study.Department of Internal Medicine, University of Pisa, Italy.A total of 209 individuals including 38 type 1 patients, 76 relatives, and 95 healthy subjects.We used the European Prospective Investigation of Cancer and Nutrition questionnaires to assess dietary intake and lifestyle. Anthropometric indices and nutritional biomarkers (such as plasma levels of albumin, iron, lipids, homocysteine, vitamin B9 and vitamin B12 as well as urinary outputs of nitrogen, sodium and potassium) were evaluated.Emerging health issues: (1) In total, 45% of controls were overweight. Increasing age was associated with increasing body mass and decreasing activity in sport in front of an unchanged energy intake. (2) The distribution of energy sources was incorrect. The proportion of caloric intake derived from total fat and cholesterol did not match general guidelines. Total dietary fibre consumption was assessed to be adequate (25 g/day) in only 27% of all the participants. (3) Estimated daily intakes of water-soluble vitamin B9 and fat-soluble vitamin D and vitamin E were deficient in comparison with dietary reference intakes. (4) The prevalence of adoption and maintenance of healthful eating and physical activity habits was higher in women and T1DM patients (probably as a consequence of the medical educational intervention). On the contrary, supportiveness of the family in term of changing the undesirable behaviours at home seemed to fail.This study provides first evidence indicating unhealthy dietary behaviours, which could even predispose to the development of diabetes and cardiovascular complications, in subjects living in Pisa. The combination of vitamin B9 and vitamin E deprivation could be deleterious for endothelial function, since these antioxidants have been implicated in the modulation of nitric oxide and eicosanoid signalling.

SUMMARYBecause abnormalities in redox balance cluster in type I diabetes families and the intracellular thiol redox status seems to modulate immune function, we aimed to investigate the relationship between oxidative stress and immunological features. We measured oxidative markers, serum proinflammatory cytokines, soluble cytokine receptors and subsets of peripheral blood lymphocytes (by varying combinations of CD4, CD8, CD23 or low-affinity IgE receptor, and CD25 or IL-2 receptor) from 38 type I patients, 76 low-risk (i.e. without underlying islet autoimmunity) non-diabetic first-degree relatives of diabetic patients, and 95 healthy subjects. In type I diabetes families, protein and lipid oxidation was confirmed by the presence of reduced sulphhydryl groups, increased advanced oxidation protein products, and increased plasma and erythrocyte malondialdehyde. Relatives had decreased counts of monocytes, of cells co-expressing CD23 and CD25 and of CD25+ cells in peripheral blood. Patients with TIDM had similar defects and, in addition, showed decreased counts of peripheral CD4+CD8+ lymphocytes and increased serum levels of soluble receptors for interleukin (IL)-6 and IL-2. Abnormal indicators of oxidative stress were related in part to immune abnormalities. In the whole study group, we found a correlation (multiple R 0·5, P

Individuals who have type 1 diabetes need individualised medical nutrition therapies whose goals are to improve overall health and metabolic outcomes. However, interventions in the field of nutrition are challenging, as diet-related correlations with disease remain difficult to detect and the certainty of outcome in this area is elusive. Currently, patients are not meeting recommended dietary guidelines. Several alternative approaches for teaching meal planning to people with diabetes have been proposed: basic nutrition guidelines, basic diabetes guidelines, menu approaches to meal planning, exchange lists for meal planning and carbohydrate counting. The review provides an overview of suggested strategies for achieving the proposed goals and summarises evidence of outcomes.

The International Diabetes Federation estimated that 5.1 million people aged between 20 and 79 years died from diabetes in 2013, accounting for 8.4% of global all-cause mortality among people in this age group. Type 1 diabetes is associated with a 2- to 4-fold increased mortality risk compared with the general population. Before the onset of late complications, most of the excess mortality is from potentially preventable causes of death such as ketoacidosis, whereas the long-term excess mortality is largely due to cardiovascular disease. However, a wide geographic variation in mortality of type 1 diabetic patients has been evidenced and accurate estimates of mortality attributable to diabetes are difficult to obtain. The review provides an overview of currently available evidence and summarizes main problems in estimating early and long-term mortality by cause of death in type 1 diabetes, paying particular attention to European studies.

Background Cardiovascular prevention requires a diagnostic approach for population-based screening programmes aimed at early identification of modifiable risk factors. Dyslipidaemia, which is a major risk factor for cardiovascular disease, remains largely undiagnosed and undertreated. Point-of-care testing (POCT) provides immediate results for clinical decision-making, however, quality assessment is essential to ensure system performance requirements. CardioChek PA (CCPA), a portable whole blood analyser for rapid lipid measurement, has been on the market since 2002 but with limited evidence of performance levels. The aim of the study was to assess analytical performance issues of the device and possibly contribute to their solution. Methods Over a 3-year period, we repeatedly evaluated CCPA accuracy, precision, and discrepancies between instruments and between test strip lots by comparison with laboratory method. At our initial evaluation, the CCPA analyser underestimated total cholesterol (bias 6.5%) and gave within-assay CVs above 6% for all lipid fractions. Our results solicited sequential improvements to the CCPA system by the manufacturer up to the performance level certified by the Cholesterol Reference Method Laboratory Network in 2013: total error 1.3% for total cholesterol and 3.1% for high density lipoprotein (HDL) cholesterol. Conclusions POCT diagnostic tests need continuous quality management, including both quality control and quality assurance, to monitor the analytical process. A 3-year external quality surveillance provided information useful in improving POCT performance. As a result, the device is now adequate for use in screening programmes aimed at early detection of lipid disorders.

Since increased plasma and cell levels of oxidative products have been found in non diabetic relatives of type 1 diabetic patients, we hypothesized the occurrence of an endothelial dysfunction in these subjects. To verify this hypothesis we investigated the skin blood flow responses to iontophoresis of both the endothelial-dependent vasodilator acetylcholine (ACh) and the endothelial-independent vasodilator sodium nitroprusside (SNP) in 31 non diabetic healthy relatives (DR) (14 siblings, 17 parents) of 17 type 1 diabetic patients. Twenty healthy control subjects (CS) without a family history of diabetes, matched for age (± 5 years) and gender, were also investigated. DR and CS did not significantly differ either in basal skin blood flux (6.75 ± 0.72 PU and 5.78 ± 0.37 PU, respectively) or in skin vasodilator response to both ACh (728 ± 53% and 711 ± 44%, respectively) and SNP iontophoresis (758 ± 71% and 731 ± 64%, respectively). This finding is consistent with a preserved skin microvascular endothelial function in the studied subjects. However, since previous data suggest that both nitric oxide (NO) and prostacyclin released form the cutaneous vascular endothelium have an interchanging compensatory role in controlling the skin vasodilator response to ACh iontophoresis, our finding does not allow a defect in NO dependent skin vasodilatation to be excluded in the studied relatives of diabetic patients.

Fetal growth is dependent on transplacental supply of fuels. We aimed to assess the effect of serial changes in maternal glucose tolerance and insulin secretion with advancing pregnancy on maternal-fetal outcomes. Sixty-nine healthy pregnant women were studied over the course of gestation for glucose tolerance, by oral glucose tolerance test (OGTT), and hemoglobin A(1c) (HbA(1c)), fetal intrauterine growth (by ultrasound) and pregnancy outcome. Seven women had an abnormal OGTT in the third trimester developing gestational diabetes mellitus (GDM), but none of the 12 mothers of large babies (3.9 kg) had GDM: the former had the highest post-load glycemic increment, despite an apparently 'normal' insulin secretory response, the latter showed the lowest post-load glucose increase in the face of the lowest insulinemic response. Neonatal body weight correlated with maternal gestational weight gain, placental weight, third trimester ratio of incremental plasma insulin and glucose integrated areas under the curve and first and second trimester HbA(1c) levels. Fetal growth indices (femur length, biparietal diameter and abdominal circumference) were correlated with both HbA(1c) and 2h OGTT. Fetal growth rate is confirmed as being associated with maternal glycemic equilibrium, but one of the main determinants of high infant birthweight seems to be an enhanced maternal insulin sensitivity, accompanied by remarkable gestational weight gain.

To better understand the links between circulating insulin and albuminuria in essential hypertension, the plasma insulin response t alpha a 75 gram glucose load and albuminuria were evaluated in 53 glucose-tolerant essential hypertensives and 12 controls. To allow any direct pressure-independent albuminuric effect of insulin to emerge more clearly, those same parameters were also evaluated in 20 glucose-tolerant normotensive patients with stable atherosclerotic peripheral vascular disease, a condition in which hyperinsulinaemia could be anticipated on the basis of previous reports. In response to glucose ingestion, hyperinsulinaemia was evident in both hypertensive and normotensive atherosclerotic patients, while, on average, urine albumin was elevated only in the former. When plasma insulin, systolic and diastolic blood pressure (BP) (by 24-h ambulatory BP monitoring), plasma glucose, triglycerides and body mass index were entered into a multiple regression analysis, only systolic BP appeared to exert an independent effect on urine albumin. Post-glucose load plasma insulin did not differ between hypertensive patients with (n = 14) and without (n = 39) microalbuminuria (albuminuria20 micrograms/min). In further analyses, insulin and systolic BP values were divided in quartiles: albuminuria did not differ across insulin quartiles, while it was significantly higher in the top (n = 21) vs the bottom (n = 21) systolic BP quartile. Thus, hyperinsulinaemia and microalbuminuria were unrelated variables in these hypertensive and atherosclerotic patients. Blood pressure, particularly systolic, emerged as a primary predictor of urinary albumin excretion, although the importance of this parameter needs to be proved prospectively.

Measurement of the urinary albumin excretion rate (UAER) is essential for the early diagnosis and monitoring of diabetic nephropathy; immunonephelometry is a procedure used worldwide for routine screening of diabetic patients. Since we have met with occasional inconsistent values of UAER in serial urine collections, we searched for possible sources of analytic error. To assess the best working conditions of the instrument in use, the stability of urine samples during storage and the need for previous urine centrifugation, we assayed repeatedly the six automatically diluted points of the standard curve (55.6 to 1.7 mg/l), four control samples of human albumin in saline (100 to 1 mg/l) and 24-h urine collections from outpatient diabetic subjects. The last were also assayed with and without previous centrifugation, and both immediately after collection as well as after storage at –20°C for 7, 42, 79, 97, 128 and 161 days. We concluded that: (1) pre-analytic centrifugation of urine samples is unnecessary; (2) the intra-assay coefficient of variation (CV) of the standard curve changed from 2.4% to 9.3% when moving from the highest to the lowest concentration; the inter-assay CV changed from 4.1% to 14.4%, respectively; (3) the intra-assay CV of the control samples (manually prepared) changed from 5.7% to 10.2% and the inter-assay CV from 7.7% to 22.9%; there was a constant and significant (P

Malnutrition, anorexia and cachexia are a common finding in cancer patients. They become more evident with tumor growth and spread. However, the mechanisms by which they are sustained often arise early in the history of cancer. For malnutrition, these mechanisms can involve primary tumor or damage by specific treatment such as anticancer therapies (surgery, chemotherapy, radiotherapy) also in cancers that usually are not directly responsible for nutritional and metabolic status alterations (i.e. bone tumors). For anorexia, meal-related neural or hormonal signals and humoral signals related to body fat or energy storage and the interaction of these signals with the hypothalamus or the hypothalamic inappropriate response play a pathogenetic role. Some cytokines are probably involved in these mechanisms. For cachexia, the production of proinflammatory cytokines by tumour cells is the initial mechanism; the main biochemical mechanisms involved include the ubiquitine proteasome-dependent proteolysis and heat shock proteins. Treatment includes pharmaceutical and nutritional interventions.

Misalignment of circadian rhythms has been evidenced in patients with type 1 diabetes and there is a close relationship between alterations in neuroendocrine sleep architecture, circa‐ dian clock oscillations, glucose metabolism, autonomic function, and diurnal profiles of blood pressure and heart rate [1-5]. In turn, circadian misalignment may modify the peak incidence of cardiovascular events in diabetic people [6-9]. Diabetic autonomic neuropathy, particularly cardiac autonomic neuropathy, is considered an important potential factor in‐ volved in the disruption of circadian cardiovascular rhythms [10]. This serious chronic com‐ plication is rarely diagnosed because it remains for a long times asymptomatic; contrariwise, it seems to have a significant prognostic value [10-12]. The review summarises the battery of non-invasive autonomic function tests available for diabetic autonomic neuropathy diagno‐ sis as well as cross-sectional and follow-up studies supporting their importance in risk strat‐ ification for diabetic micro-vascular complications and cardiovascular morbidity/mortality.

It has been recently hypothesized that peripheral microvascular dysfunction may contribute to atherosclerotic damage (AD) in diabetic patients. In order to test this hypothesis, we assessed forearm skin post-occlusive reactive hyperaemia (skin-PORH), an index of peripheral microvascular function, using laser-Doppler flowmetry, in 40 type 1 diabetes patients (T1D-pts), aged 49 ± 11 years, with no known cardiovascular complications, and in 50 age and sex-matched healthy control subjects (CS). T1D-pts also underwent carotid arteries ultrasound scanning (Ca-US) and ankle-brachial index (ABI) measurement. An arbitrary index of AD (AD-index), ranging from "0" (normal ABI, normal Ca-US) to "3" (abnormal ABI, one or more plaques at the Ca-US), was determined in T1D-pts. Linear and multiple regression analyses were performed to identify independent predictors of AD in T1D-pts. T1D-pts had a lower skin-PORH compared with CS (p = 0.015). In T1D-pts AD-index resulted to be negatively related with skin-PORH (R = 0.44; p < 0.005) or deep-breathing test (DBT) (R = 0.53; p < 0.0005), and positively related with systolic arterial pressure (R = 0.31; p < 0.05), microalbuminuria (R = 0.46; p < 0.005), patients' age (R = 0.51; p < 0.001) and diabetes duration (R = 0.39; p < 0.05). At the multiple regression analysis skin-PORH (R = 0.36; p < 0.005), patients' age R = 0.24; p < 0.05) and DBT (R = 0.4 - p < 0.005) resulted to be independent predictors of AD-index in T1D-pts. These preliminary findings support the hypothesis that peripheral microvascular dysfunction may contribute to AD in T1D-pts.

Background: There is controversy about absolute number, frequency, and status of homing markers of regulatory T (Treg) cells in patients with type 1 diabetes. We observed recently a considerable accumulation of terminally differentiated central memory subsets among CD4+ and CD8+ T cell expressing CD26 in patients with type 1 diabetes. The increased number of terminally differentiated central memory cells, which was positively associated with HbA1c levels, could suggest life-long stimulation by protracted antigen exposure or a homeostatic defect in the regulation/contraction of immune responses. Methods: We have analysed the phenotype of peripheral blood Treg cells in adult patients with type 1 diabetes using an 8-color flow cytometry assay panel for the characterisation of CD4+CD25highCD127- Treg cells into naive (N, CCR7+CD45RA+), central memory (CM, CCR7+CD45RA-), and effector memory (EM, CCR7-CD45RA-) cells. We also examined the expression of two additional markers: the serine protease CD26 that has been recently suggested as a negative selection marker for human Treg cells, and the cutaneous lymphocyte-associated antigen, given that the bidirectional homing of Treg cells between the skin and lymph nodes is important for efficient regulation. Results: We found that patients with type 1 diabetes had normal Treg frequencies but a low proportion of CCR7- EM Treg cells, which was inversely correlated with both a long-term indicator of glycaemic control such as HbA1c and an indicator of renal function such as plasma creatinine. Conclusion: In our opinion, present results seem to support the second of the two initial hypotheses, i.e. a defect in regulation/suppression of immune homeostasis in diabetic people. Moreover, the worse glycaemic control (evaluated by HbA1c), the higher frequency of immune defects and more severe.

Kidney involvement in immuno-mediated diseases is a life threatening complication to be early detected. Glomerulo-tubular functional indices, kidney-released enzymes and metabolic profiles were assessed in 21 patients with systemic lupus erythematosus, progressive systemic sclerosis and mixed cryoglobulinaemia, without overt nephropathy at a current laboratory examination, and in 31 age-sex-matched healthy controls. All patients had a urinary total protein excretion rate higher than controls (353.6 +/- 182.4 vs 243.0 +/- 108.2 mg/24 h, p0.01); 12 of them resulted albuminuric (775.5 +/- 1192.4 mg/24 h), while 9 were normoalbuminuric (16.6 +/- 7.6 mg/24 h). Urinary enzyme excretion rates (GGT and NAG) were significantly heightened compared to healthy subjects, both in albuminuric and in normoalbuminuric patients. Serum albumin resulted significantly lower in all patients, independent of their urinary albumin leakage. Finally, all subjects with connective tissue diseases had significantly higher triglycerides, lower HDL cholesterol and double serum fasting insulin than normals. In conclusion, all patients with collagen diseases show signs of subclinical nephropathy, not always detectable by albuminuria. They also provide evidence of insulin-resistance, a conceivable forerunner of cardiovascular complications.

Circadian misalignment has been implicated in the development of diabetes mellitus and cardiovascular disease. Circadian rhythms of blood pressure (BP) and heart rate (HR) have long been known and the mechanisms controlling them have been actively investigated in physiology and disease. In this respect, the introduction of 24-hour ambulatory blood pressure monitoring (ABPM) has enabled a more accurate assessment of circadian BP patterns in order to solve diagnostic uncertainty or to establish dipper status. However, attention has been mainly focused on measures of extent (midline estimating statistic of rhythm, MESOR, and amplitude) rather than timing (acrophase) of changes within a cycle. The review summarises 1) evidence for altered characteristics of BP rhythm (in particular, phase shifts along the time axis) in animal and human diabetes mellitus, 2) the mechanisms that have been supposed to underlie the observed changes in cardiovascular function before diabetes onset and during progression of the disease, and 3) the adverse consequences that may result from an altered circadian BP rhythm.

Anorexia Nervosa (AN) and Obesity are prevalent in modern societies. This study evaluate circulating levels of Neuropeptide Y (NPY) and of Peptide Tyrosine-Tyrosine (PYY) in 60 women: 20 affected by AN (Body Mass Index = BMI 15.74 ± 2.09 kg/m2, age 30.19 ± 10.52 yr), 10 restrictor (BMI 14.89 ± 1.64 kg/m2) and 10 binge-purge subtype (BMI 18.27 ± 0.81 kg/m2); 20 affected by severe Obesity (BMI>40 kg/m2; age 33.56 ± 5.2 yr) with type II diabetes with no therapy, and 20 healthy controls (BMI 22.06 ± 0.93 kg/m2, age 32.44 ± 4.35 yr). NPY is higher in AN than obese and controls (70.17 ± 20.84 vs 25.12 ± 7.26 and 52.20 ± 10.88 pmol/L; p

Arterial hypertension and poor glycaemic control are central to the development of microalbuminuria in insulin-dependent diabetes mellitus (IDDM). Recent consensus has established sensitive criteria for their detection and treatment, although the proportion of patients who may benefit is unclear. Between 1988 and 1990, we measured urinary albumin to creatinine concentration ratio (A/C) in 3,636 adult out-patients with IDDM of more than 3 years duration, serum creatinine under 133 mumol/l and who were not undergoing antihypertensive treatment. A/C indicating microalbuminuria (or = 2.38/2.96 mg/mmol, male/female) was found in 620 of 3,451 patients without proteinuria, and associated with hypertension (blood pressureor = 140 and/or 90 mmHg; p = 0.0016; rate: 39.6%), independent of diabetes duration (p = 0.0082) and male gender (p = 0.0350; relative risk = 1.16; 95% confidence interval: 1.01-1.32). Hypertension was less common among those with normal A/C (27.5%, p0.0001) but was positively related with diabetes duration. Of the 1,015 patients with A/Cor = 2.0 mg/mmol 529 were reexamined. Glycated haemoglobin levels exceeded 3 SD above the mean of normal in 84.3% of the 198 microalbuminuric patients (AER = 20-200 micrograms/min), but were comparably poor (79.2%) in normoalbuminuria. Duration of diabetes was inversely related to glycated haemoglobin only in microalbuminuria (0.05p0.1). Intervention to lower blood pressure remains mainly restricted to those patients with long-term diabetes and slower development of kidney disease. Near-normalisation of glycaemia remains the priority for the majority of patients with microalbuminuria.

Microalbuminuria (urinary albumin excretion between 20 and 200 micrograms/min) and endothelial dysfunction coexist in patients with essential hypertension. To evaluate whether the two phenomena are related and the determinants of that association, we recruited 10 untreated males with essential hypertension and microalbuminuria without diabetes to be compared with an equal number of matched patients with essential hypertension excreting albumin in normal amounts and 10 normal controls. The status of endothelial function was inferred from circulating von Willebrand Factor antigen (vWF), a glycoprotein secreted in greater amounts when the vascular endothelium is damaged. vWF concentrations were higher in hypertensive patients with microalbuminuria than in hypertensive patients without and controls. Individual vWF and urine albumin-excretion values were correlated (r = 0.55, p < 0.002). Blood pressure correlated with both urinary albumin excretion and vWF. Left ventricular mass index and minimal forearm vascular resistances were comparable in patients with hypertension and higher than in controls; total and low-density lipoprotein cholesterol, triglycerides, lipoprotein-a, Factor VII, and plasminogen activator inhibitor-1 did not differ. Fibrinogen was higher and creatinine clearance lower in microalbuminurics. Albuminuria in essential hypertension may reflect systemic dysfunction of the vascular endothelium, a structure intimately involved in permeability, haemostasis, fibrinolysis, and blood pressure control. This abnormality may have important physiopathological implications and expose these patients to increased cardiovascular risk.

Type 1 diabetes is an autoimmune process predominantly T-cell mediated. CD26 plays a role in T-cell costimulation, migration, memory development, thymic maturation and emigration patterns. In peripheral blood from 55 patients with type 1 diabetes and 20 healthy controls, CD4(+) and CD8(+) T cells expressing CD26 were differentiated into naive (N, CD45RA(+)CCR7(+)), central memory (CM, CD45RA(-)CCR7(+)), effector memory (EM, CD45RA(-)CCR7(-)), and terminally differentiated effector memory (TEMRA, CD45RA(+)CCR7(-)). In type 1 diabetes, CD4(+) and CD8(+) T cells expressing CD26 showed a distinctive differentiation profile: percentages and absolute numbers of CM and N cells were reduced, whereas those of TEMRA cells were markedly increased. The indices of intermediate- and long-term glycaemic control were associated negatively with the number of CM and N cells while positively with the number of TEMRA cells. The considerable accumulation of TEMRA T cells in our patients suggests life-long stimulation by protracted antigen exposure (viruses, other agents or residual self-antigens?) or a homeostatic defect in the regulation/contraction of immune responses.

Type 1 diabetes is a chronic metabolic disease whose aetiology and pathogenesis remain not completely understood. Current criteria for the diagnosis of diabetes are: 1) haemoglobin A1c ≥ 6.5% (assayed using a method that is certified by the National Glycohemoglobin Standardization Program, NGSP, and standardised or traceable to the Diabetes Control and Complications Trial, DCCT, reference assay), 2) fasting plasma glucose (FPG) ≥ 126 mg/dl, 3) 2-hour plasma glucose ≥ 200 mg/dl during an oral glucose tolerance test (OGTT, 75 g), 4) a random plasma glucose ≥ 200 mg/dl (American Diabetes Association, 2011). The classification of diabetes includes: type 1 diabetes, type 2 diabetes, other specific types of diabetes due to other causes, and gestational diabetes mellitus. Type 2 diabetes, which is usually associated with obesity and older age, results from insulin resistance and progressive failure of pancreatic beta-cell function. Type 1 diabetes, which has usually an abrupt onset in younger people, is an organ-specific autoimmune disease characterised by absolute insulin deficiency resulting from beta-cell destruction. However, autoimmunity may not be the primary cause: environmental triggers are believed to precipitate type 1 diabetes in genetically susceptible individuals (van Belle et al., 2011). The overall incidence of type 1 diabetes is increasing; the majority of the increase is observed in the youngest age group, which also appeared to be the heaviest (Evertsen et al., 2009). Indeed, the accelerator hypothesis (Wilkin, 2009) suggests that type 1 and type 2 diabetes are the same disorder of insulin resistance set against different genetic backgrounds. Three processes could variably accelerate the loss of beta cells through apoptosis: constitution, insulin resistance, and autoimmunity. None of these accelerators leads to diabetes without excess weight, which causes an increase in insulin resistance and, thus, the weakening of glucose control. In turn, the glucotoxicity accelerates beta-cell apoptosis directly and by inducing beta-cell immunogens and autoimmunity in genetically predisposed subjects. Insulitis is commonly observed in recent-onset type 1 diabetes, but it does not uniformly affect all insulincontaining islets (differences in islet function?). It has been suggested that under increased insulin demand (puberty, adolescence, high sugar intake, etc.) a population of islets may be more prone to dysfunction or death, thereby attracting antigen presenting cells and

We tested the level of knowledge on diabetes and professional skills in a group of 60 non-diabetological health care professionals at the Policlinic of Pisa regarding the recognition and treatment of hypoglycaemia, the storage, mixing and administration of insulin, blood glucose stick monitoring, and the prevention and treatment of diabetic foot. The evaluation was carried out using a multiple-choice questionnaire and observation of the subjects, performance by means of pre-defined observation schedules, during the preparation and administration of a blend of rapid-intermediate insulin, the use of blood glucose sticks and the management of a simulated hypoglycaemic crisis. As regards hypoglycaemia, 90% of subjects did not give a correct definition, 88.3% were unaware of the existence of asymptomatic hypoglycaemia, and 96.6% did not give a complete answer as to the treatment of hypoglycaemia. For insulin, 51.7% did not know the standards for correct storage of insulin, 88.3% did not know the difference between "clear" and "opaque" insulins, and 91.7% ignored the required interval between administration of regular insulin and meals. For foot care, 45% admitted that the problems with diabetics' feet were frequently not controlled, and between 21.7% and 63.3% did not known the hygiene rules for feet. Assessment of the performance of the subjects using schedules revealed incorrect use of sticks and administration of insulin (80.2% mixed and 92.4% injected the insulin incorrectly). There is clearly a need for education of non-diabetological health professionals regarding the disease. This is supported by the health professionals themselves, 94.5% of whom wished to participate in a course on diabetes.

Proteins are susceptible to free radical damage. We measured advanced oxidation protein products (AOPP) in the plasma of 56 hospitalised patients. Concentrations of AOPP were expressed as chloramine-T equivalents by measuring absorbance in acidic conditions at 340 nm in the presence of potassium iodide. We also determined erythrocyte sedimentation rate (ESR), circulating urea, creatinine, glucose, uric acid, electrolytes, lipids, total proteins and fractions and fibrinogen. Twenty-four samples were processed both immediately and after 7, 15, 30, 90, 180 and 438 days of storage at both at -20 degrees C and -80 degrees C (aliquots were frozen and thawed only once) to evaluate AOPP stability. The remaining 32 samples were also processed for thiobarbituric-acid-reactive substances (TBARS). Mean AOPP concentration in all 56 patients was 48.3+/-37.2 microM. Mean basal concentration of AOPP in the 24 plasma samples (55.0+/-47.1 microM) showed no significant change at each intermediate determination, yet significantly increased after 438 days of storage both at -80 degrees C (96.6+/-83.2, p0.01) and, markedly, at -20 degrees C (171.3+/-94.6, p0.001). TBARS concentration was 1.59+/-0.65 micromol/l. Multiple regression analysis evidenced that AOPP concentration was positively correlated (multiple r=0.62, p0.001) with serum urea and triglycerides, but negatively correlated with patient age (indeed, serum albumin and total proteins decreased with increasing age, r=0.3, p0.05). TBARS concentration was associated with ESR and serum glucose (multiple r=0.73, p0.001), yet positively with AOPP (r=0.39, simple p0.05). We conclude that AOPP remain stable during sample storage both at -20 degrees C and -80 degrees C for 6 months. Renal failure and hypertriglyceridemia probably enhance the in vivo process of AOPP formation. Oxidative damage as measured by TBARS may be increased because of exposure to hyperglycemia causing nonenzymatic glycation of plasma proteins.

Background Normotensive non-diabetic relatives of type 1 diabetes (T1D) patients have an abnormal blood pressure response to exercise testing that is associated with indices of metabolic syndrome and increased oxidative stress. The primary aim of this study was to investigate the circadian variability of blood pressure and the ambulatory arterial stiffness index (AASI) in healthy siblings of T1D patients vs healthy control subjects who had no first-degree relative with T1D. Secondary aims of the study were to explore the influence of both cardiovascular autonomic function and erythrocyte electron transfer activity as oxidative marker on the ambulatory blood pressure profile. Methods Twenty-four hour ambulatory blood pressure monitoring (ABPM) was undertaken in 25 controls, 20 T1D patients and 20 siblings. In addition to laboratory examination (including homeostasis model assessment of insulin sensitivity) and clinical testing of autonomic function, we measured the rate of oxidant-induced erythrocyte electron transfer to extracellular ferricyanide (RBC vfcy). Results Systolic blood pressure (SBP) midline-estimating statistic of rhythm and pulse pressure were higher in T1D patients and correlated positively with diabetes duration and RBC vfcy; autonomic dysfunction was associated with diastolic BP ecphasia and increased AASI. Siblings had higher BMI, lower insulin sensitivity, larger SBP amplitude, and higher AASI than controls. Daytime SBP was positively, independently associated with BMI and RBC vfcy. Among non-diabetic people, there was a significant correlation between AASI and fasting plasma glucose. Conclusions Siblings of T1D patients exhibited a cluster of sub-clinical metabolic abnormalities associated with consensual perturbations in BP variability. Moreover, our findings support, in a clinical setting, the proposed role of transplasma membrane electron transport systems in vascular pathobiology.

Assessing modifiable risk factors for metabolic and cardiovascular diseases prior to the onset of disease could allow effective prevention initiatives. Equally, monitoring in diabetic people glucose, haemoglobin A1c, ketones, lipid profiles, and urinary microalbumin concentrations allows the prevention, early detection, and treatment of diabetes-related acute and chronic complications and has a positive impact on the process of care in the management of patients with diabetes. The point-of-care testing (PoCT) technology offers convenient aspects: immediate results, decision-making without the need for repeated visits, use of fingerstick blood samples. More patients could be identified at early stages of their disease/complication provided that pre-analytical, analytical, and post-analytical errors are minimised. Indeed, prediction requires instruments with proved precision, accuracy, validity, and reliability. Reference laboratory services are now available to manufacturers so to confirm PoCT results. There are several PoC devices on the market that may allow for "real time" screening, diagnosis, and monitoring in diabetes care. Tight glucose control has a key role in long-term health of diabetic people and in the primary prevention of diabetic chronic complications. Diabetic patients are currently educated to control capillary glucose levels daily in order to maintain them within target limits. Blood glucose meters are widely used not only by diabetic patients to self-manage their disease but also by physicians to monitor critically ill patients. Glycated haemoglobin A1c can now be measured with fast and easy automated PoCT instruments to monitor long-term serum glucose regulation. Urinalysis dipsticks and blood betahydroxybutyrate meter allow measuring urine and blood ketones to prevent ketoacidosis. Since the routine measurement of urinary albumin has been suggested in diabetes mellitus as a predictor of overt diabetic nephropathy, semi-quantitative visual dipsticks and quantitative automated methods of urine testing became available for bedside detection of urine albumin at low concentrations and for the determination of the microalbumin creatinine ratio. While the National Cholesterol Education Program recommends that all adults aged 20 years and over have their blood cholesterol checked at least once every 5 years, adult diabetic patients should measure fasting lipid profile at least annually or every two years in case of low-risk lipid values. There are PoCT devices on the market that provide a full lipid panel (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides). The overview summarises current state-of-the-art of PoCT in diabetes care.
