<P>Background: Type 2 diabetes (T2DM) is a risk factor for Alzheimer’s disease and mild cognitive impairment. The etiology of cognitive impairment in people with T2DM is uncertain but, chronic hyperglycemia, cerebral micro vascular disease, severe hypoglycemia, and increased prevalence of macro vascular disease are implicated. </P><P> Objectives: To determine the serum levels of soluble vascular adhesion molecule (sVCAM-1) and highly sensitive C-reactive protein (hs-CRP) in elderly type 2 diabetics with mild cognitive impairment (MCI). Methods: Our study was conducted on 90 elderly subjects (aged 60 years old or more). They were divided into Group І, 30 patients with T2DM and mild cognitive impairment, group ІІ, 30 patients with T2DM without cognitive impairment and group III, 30 healthy subjects as a control group. They were subjected to history taking, full clinical examination, anthropometric measurement, the Addenbrooke’s Cognitive Examination III (ACE---III 2012), Fasting plasma glucose, 2 hours plasma glucose, HbA1c, lipid profile, protein/creatinine ratio, serum sVCAM-1 and hs-CRP. Results: Serum levels of sVCAM-1 in diabetic elderly patients with MCI were significantly higher (946.7 ± 162.01 ng/ml) than diabetic elderly patients without cognitive impairment (479.06 ± 65.27 ng/ml) and control (263.7 ± 72.05 ng/ml) with (P=0.002). Serum levels of Hs-CRP in diabetic elderly patients with MCI were significantly higher than as diabetic elderly patients without cognitive impairment and control with (P=0.005). Conclusion: Elderly diabetic patients with mild cognitive impairment have higher levels of soluble adhesion molecules and markers of low-grade systemic inflammation than other groups.</P>

<b><i>Background/Aims:</i></b> QT prolongation is a known risk factor for ventricular fibrillation and ventricular tachycardia. Therefore, more refined management is necessary to reduce sudden cardiac death secondary to such arrhythmias. <b><i>Methods:</i></b> Electrocardiographic findings were reviewed in 224 patients, and the associations of QT prolongation with various clinical parameters were examined, including the nutritional state. Correlations were also examined between QT prolongation and body composition measurements determined by multifrequency bioelectrical impedance analysis. <b><i>Results:</i></b> Prolongation of the corrected QT (QTc) interval over 0.44 s was seen in 140 patients (62.5%). QT prolongation was independent of age and dialysis therapy duration and was more frequent in diabetics (70.1%) than in nondiabetics (54.2%, <i>p</i> = 0.014) and more frequent in women (78.8%) than in men (53.5%, <i>p</i> &#x3c; 0.001). Serum levels of albumin (<i>p</i> &#x3c; 0.001) and Cr (<i>p</i> &#x3c; 0.001) and the Geriatric Nutritional Risk Index (GNRI, <i>p</i> &#x3c; 0.001) were negatively correlated with QTc interval; no significant correlation was noted with total protein, urea nitrogen, or uric acid. Negative correlations with QTc interval were found for BMI(<i>p</i> &#x3c; 0.01), percent total body water (%TBW; <i>p</i> &#x3c; 0.05), and percent intracellular water (%ICW; <i>p</i> &#x3c; 0.01) but not with the percent extracellular water/TBW ratio or edema ratio. The longer the QTc interval, the lower the fat-free mass (FFM; <i>p</i> &#x3c; 0.01) and muscle mass (MM; <i>p</i> &#x3c; 0.01), but there was no significant correlation with percent fat. <b><i>Conclusion:</i></b> These results suggest that QT prolongation is a common complication and is more frequent in women and diabetic patients. The decreases in serum albumin and Cr levels, GNRI, BMI, %TBW, %ICW, FFM, and MM together coincided with malnutrition and thus suggest a close relationship of QT prolongation with malnutrition. Management of QT prolongation may be achieved better in the future by understanding these biochemical and biophysical changes, particularly those regarding malnutrition.

Introduction: Coronary artery disease is the leading cause of mortality in diabetics. Due to the diffuse nature of their disease, diabetics may be at risk for incomplete revascularization, highlighting a potential role for pro-angiogenic therapy in this group. This study investigates molecular mechanisms of angiogenesis in diabetics. Methods: Myocardial tissue was harvested from patients undergoing CABG (non-diabetic (ND) 11, type 2 diabetic (DM) 10). Expression of angiostatin, endostatin, their precursors (plasminogen and collagen XVIII, respectively), enzymes leading to their production (Matrix Metalloprotease (MMP) 2 & 9), and an inhibitor of MMPs (TIMP2) was assessed with western blotting. MMP activity was assessed. Serum levels of angiostatin and endostatin were assayed. Coronary collateralization was graded by Rentrop scoring of angiograms. Results: Plasminogen and collagen XVIII expression were similar between groups. Angiostatin expression trended to increase 1.24-fold (p=0.07) and endostatin expression increased 2.02-fold in DM patients relative to ND (p=0.02). Serum angiostatin was 2.68-fold higher (p=0.03) and endostatin 1.39-fold higher (p=0.04) in diabetics. MMP9 expression was no different between groups, whereas MMP2 expression decreased 1.8-fold in diabetics (p=0.003). MMP2 & 9 activity decreased 1.33-fold (p=0.03) and 1.57-fold (p=0.04), respectively, in diabetics. Coronary collateralization scores were ND 2.1 ± 0.37 vs. DM 1.0 ± 0.4 (p=0.05). Myocardial endostatin expression correlated strongly with %HbA1c (R=0.742, p=0.0001). Myocardial expression of angiostatin and endostatin demonstrated significant negative linear correlations with coronary collateralization (angiostatin R=−0.531, p=0.035, endostatin R=−0.794, p=0.0002). Conclusion: Diabetics exhibit increased levels of the anti-angiogenic proteins angiostatin and endostatin and differential regulation of the enzymes governing their production relative to non-diabetics. Myocardial levels of these proteins show significant correlation to coronary collateralization. These findings offer potential new therapeutic targets for enhancing pro-angiogenic therapy and insight in to the angiogenic impairments seen in diabetes.

Abstract Background and Aims Dietary protein restriction is rediscussed as mainstay approach in advanced Chronic Kidney Disease (CKD), both in diabetics and non-diabetics to defer renal replacement therapy (RRT), mainly by better metabolic control; improvements in mineral bone disorders (MBD) were also suggested, but less studied in Diabetic Kidney Disease (DKD). An unicentric prospective interventional trial aimed to assess the effects of ketoanalogue-supplemented low protein diet (sLPD) on proteinuria and CKD progression (data already presented). The parameters of MBD were also evaluated. Method Adult diabetic patients (452) with stable CKD stage 4+, proteinuria&gt;3g/g creatininuria and SGA A were enrolled in a run-in phase (3 mo), with LPD (0.6g/kg dry ideal bw). Those who proved adherent (92, 64% males, median age 55.7 yrs, 65% on insulin) received sLPD (Ketosteril®, 1 tablet/10kg) for 12mo. Monitoring and treatment followed the Best Practice Guidelines. The primary endpoint was proteinuria during intervention as compared to pre-enrolment. Serum levels of calcium, phosphates and iPTH were considered to assess MBD. Nutrition, inflammation (SGA, BMI, serum albumin, CRP) and compliance were safety parameters. Results In patients with advanced DKD and severe proteinuria, sLPD was associated with a 69 (63; 82) % reduction in proteinuria (data presented). Significant amelioration in MBD was noted: serum levels of calcium and phosphates were significantly ameliorated at the end of the study as compared to enrolment - 4.3 (4.2-4.9) vs 3.2 (3.1-3.5) mg/dL and 5.4 (4.9-6.1) vs 8.2 (7.8-8.9) mg/dL, respectively. Serum iPTH significantly decreased: 185 (168-212) vs 375 (354-585) pg/mL. The need for calcium supplementation decreased: 6.5 (6.0-6.7) vs 7.0 (6.8-7.3) g/day. Vitamin D was required by only 35% vs 65% of patients. Nutritional status was preserved and dietary compliance was very good throughout the study. Conclusion In patients with advanced DKD ketoanalogue supplemented low protein diet seems to be effective and safe as part of MBD management.

Abstract. A radioimmunoassay has been developed for IGF-II, using Sepharose-coupled antibodies. Porcine insulin, human insulin and human proinsulin showed no cross-reaction, whereas the cross-reaction for IGF-I was 10%. To minimize the influence of the binding protein(s), all serum samples were extracted with acid ethanol before assay. The mean serum level of immunoreactive IGF-II and 95% confidence limit in 46 healthy adults were 587 ng/ml and 354–974 ng/ml, respectively. In contrast to the declining levels of IGF-I with increasing age, no such age-dependent decrease was found for IGF-II levels between 20 to 70 years. No difference in IGF-II levels was found between patients with acromegaly and healthy adult controls. In cord serum and serum from adult patients with GH deficiency the levels were significantly lower (P < 0.001) compared to controls. In diabetic patients with uraemia the mean level and 95% confidence limit were 1222 ng/ml and 532–2808 ng/ml, respectively. Thus, significantly increased serum levels of immunoreactive IGF-II have only been found in serum from patients with uraemia. Whether this is due to an increased production of IGF-II, or secondary to other factors such as the binding protein(s), will require further investigation.
