Background: Although myocardial ischemia is known to be significantly related to the development of coronary collateral vessels (CCVs), there is considerable variation between patients with ischemic heart disease in the presence of collateral development. The nature of this variability is not well known. Likewise, it remains unclear whether diabetes mellitus (DM) has any effect on CCVs. The aim of this study was to evaluate the effect of DM on CCVs. Methods: A total of 100 patients who had a stenosis of >95% in any major coronary artery in angiograms were included in the study. Of these patients, 30 patients constitute the diabetic group. Remaining 70 patients were non-diabetic. For case-control matching, 30 non-diabetic patients (mean age, 52.03± 8.69 years) were selected randomly and were included in the control group. The CCVs were graded according to the Rentrop scoring system, and the collateral score was calculated by summing the Rentrop numbers of every patient. Results: There was no statistical difference between patients with and without DM in clinical baseline characteristics. The mean number of diseased vessels in the DM group (2.10±0.76) was higher than that in the nondiabetic group (1.63± 0.72 P.017). The mean collateral score was (1.13± 0.86) in the DM group and (1.97± 1.61) in the control group. After confounding variables were controlled for, the collateral score in the diabetic group was significantly different from that in the nondiabetic group (p=0.015). Conclusions: Our findings suggest that CCV development is poorer in patients with DM than in patients without DM. Thus, we can speculate that DM is an important factor affecting CCV development.

Background: Diabetes mellitus is associated with structural changes in corneal endothelial cells and their thickness. The present study was done to compare the endothelial cell density (ECD), central corneal thickness (CCT) and morphology in diabetic and non-diabetic patients.Methods: A cross-sectional study was conducted at Minto Ophthalmic hospital, BMC and RI Bangalore for a period of 20 months (October 2013 - May 2015). A total of 200 study subjects, 100 diabetics and 100 non-diabetic age matched controls were selected, and complete timed ophthalmic evaluation was performed. Specular microscopy was performed on all patients for endothelial cell count assessment and corneal thickness was measured by Pachymeter. The data was analyzed and represented using descriptive statistics. ‘t’ test was used for comparing the two groups.Results: The mean endothelial cell density in diabetic group was significantly lower (2438.73±250.23cells/mm2) compared to non-diabetic group (2599.88±168.16cells/mm2) (p<0.0001). The mean Central corneal thickness in diabetic group was significantly higher (518.40±28.13 μm) compared to control group (490.14±24.31 μm) (p<0.001). The Co-efficient of variation percentage of the diabetics was higher than the non-diabetics but this difference was not statistically significant (P>0.05). The hexagonality percentage was significantly lower in diabetic group compared to the controls suggesting less pleomorphism in the diabetic group.Conclusions: The study concludes that the endothelial cell density was lower and central corneal thickness was higher in diabetic patients compared with the non-diabetics. The altered endothelial morphology was significantly seen in the form of pleomorphism (hexagonality) but polymegathism was not significantly altered.

Purpose. To evaluate the ability of frequency-doubling technology (FDT) perimetry in detecting visual field defects in young adults with type I diabetes prior to retinopathy or with minor retinovascular changes.Methods. This comparative cross-sectional study included 30 healthy subjects and 73 age-matched patients with type I diabetes mellitus. All subjects underwent a full ocular examination including an FDT with the threshold C-20-5 strategy. Only one eye per subject was randomly included in the statistical analysis. FDT results and time to perform the test were compared between the groups.Results. The mean age was 27.1 years in the control group and 26.6 years in the diabetic group (P=0.875). The mean period from the onset of diabetes was12.6±6.7years, while minimal retinovascular changes were observed in 18 eyes. Mean deviation of FDT did not differ between the groups. Although global indices of FDT were within normal limits, pattern standard deviation of FDT was higher in the diabetic group (P=0.035). The area under the receiver operating characteristic curve was 0.647 for pattern standard deviation of FDT (standard error = 0.052;P=0.017).Conclusion. FDT can detect retinal dysfunctions in diabetic patients prior to the onset of significant vascular complications.

Diabetes can be linked with impaired host immunity that subsequently increases the rate of various infections including tuberculosis (TB), particularly in developing countries where TB is endemic. The objectives of this case control study were to determine the prevalence and the risk of LTBI among diabetic patients. It is a prospective case control study conducted in Azadi Teaching Hospital from September 2017 until May 2018. The diabetic patients included in this study were randomly selected. The diagnosis of diabetes mellitus (DM) was made according to the American Diabetes Association (ADA). Diabetes mellitus patients and the control participants were offered a voluntary tuberculin skin test (TST). The TST ≥10 mm was considered positive. The results were analyzed by entering the data in SPSS (statistical package for the social sciences, version 16; SPSS Inc., Chicago, Illinois, USA). Two hundred DM patients and 208 control individuals participated in this study. Collectively, 28 patients had positive TST results. Based on the sputum smear microscopy and CXR, none of these patients showed active TB disease. The differences between the DM patients and the control group had no statistical significance apart from previous hospitalization. The prevalence of LTBI was 23.53% in the diabetic group, whereas, it was 9.62% in the control group. The frequency of LTBI in diabetic patients was significantly higher than the control group. When the diabetic group was compared with the control group in terms of diabetic control and the duration of diabetes disease, there was a statistically significant association of diabetes duration ≥ 10 years and TST positivity. In conclusion, the previous hospitalization was a significant risk factor for diabetic patients to acquire TB bacilli. Latent TB infection was more common in diabetics than non diabetics and there was an increased likelihood of having LTBI with the duration of diabetes ≥ 10 years. To avoid the threatening of TB control program, prophylactic treatment of LTBI in diabetic patients is paramount.Asian J. Med. Biol. Res. June 2018, 4(2): 227-232

<p>In addition to known risk factors, the role of different micronutrients such as selenium in diabetes incidence has been proposed. Some previous studies have shown an association of selenium deficiency and type 2 diabetes mellitus, while other studies have not confirmed such a relationship. The aim of this study was to evaluate serum level of selenium in patients with Type 2 diabetes compared with the control group. This cross-sectional study was carried out on patients with type 2 diabetes in Zahedan, southeastern Iran. One hundred newly diagnosed type 2 diabetic patients were evaluated for serum selenium level. One hundred subjects from the general population who had normal fasting blood sugar levels were selected as the control group. The control group subjects were matched in pairs with each of patients on the basis of sex, age (± one year), and body mass index (±1). Serum level of selenium was determined by spectrometry method. Results were compared using t-test. The mean serum level of selenium in patients was 94.47±18.07 µg/L whereas in control group was 142.79±23.67 µg/L. The mean serum level of selenium was significantly different between the two groups (P&lt;0.001). Serum levels of selenium in diabetic patients with significant difference statistically were lower than the control group. In order to evaluate serum level of selenium in patients with diabetes, studies with larger sample size are required. Likewise, prospective studies along with selenium supplementation and investigating its effect on incidence of diabetes are accordingly needed.</p>

AbstractThe aim of this study was to measure macular perfusion in patients with type 1 diabetes and no signs of diabetic retinopathy (DR) using volume rendered three-dimensional (3D) optical coherence tomography angiography (OCTA). We collected data from 35 patients with diabetes and no DR who had OCTA obtained. An additional control group of 35 eyes from 35 healthy subjects was included for comparison. OCTA volume data were processed with a previously presented algorithm in order to obtain the 3D vascular volume and 3D perfusion density. In order to weigh the contribution of different plexuses’ impairment to volume rendered vascular perfusion, OCTA en face images were binarized in order to obtain two-dimensional (2D) perfusion density metrics. Mean ± SD age was 27.2 ± 10.2 years [range 19–64 years] in the diabetic group and 31.0 ± 11.4 years [range 19–61 years] in the control group (p = 0.145). The 3D vascular volume was 0.27 ± 0.05 mm3 in the diabetic group and 0.29 ± 0.04 mm3 in the control group (p = 0.020). The 3D perfusion density was 9.3 ± 1.6% and 10.3 ± 1.6% in diabetic patients and controls, respectively (p = 0.005). Using a 2D visualization, the perfusion density was lower in diabetic patients, but only at the deep vascular complex (DVC) level (38.9 ± 3.7% in diabetes and 41.0 ± 3.1% in controls, p = 0.001), while no differences were detected at the superficial capillary plexus (SCP) level (34.4 ± 3.1% and 34.3 ± 3.8% in the diabetic and healthy subjects, respectively, p = 0.899). In conclusion, eyes without signs of DR of patients with diabetes have a reduced volume rendered macular perfusion compared to control healthy eyes.

Purpose: The purpose of this study was to determine the effects of diabetic complications on oxidation of proteins, lipids, and DNA and to investigate the relationship between oxidative damage markers and clinical parameters. Methods: The study group consisted of 69 type 2 diabetic patients (20 patients without complication, 49 patients with complication) who attended internal medicine outpatient clinics of Istanbul Education and Research Hospital and 19 healthy control subjects. In serum samples of both diabetic patients and healthy subjects, 8-hydroxy-2’deoxyguanosine (8-OHdG), as a marker of oxidative DNA damage, Nε-(hexanoyl)lysine (HEL) and 15-F2t-iso-prostaglandin (15-F2t-IsoP). as products of lipooxidative damage, advanced oxidation protein products (AOPP), as markers of protein damage, and paraoxonase1 (PON1) as antioxidant were studied. Results: 15-F2t-IsoP (p < 0.005) and AOPP (p < 0.001) levels were significantly higher in diabetic group than control group while there were no significant differences in levels of 8-OHdG and HEL between the two groups. AOPP (p < 0.001) and 8-OHdG (p < 0.001) were significantly higher in diabetic group with complications compared to diabetic group without complications. Conclusions: Increased formation of free radicals and oxidative stress, under conditions of hyperglycaemia, is one of the probable causes for evolution of complications in diabetes mellitus. Our study supports the hypothesis that oxidant/antioxidant balance is disturbed in diabetic patients.

Abstract Background: The objective of this study was to investigate the effects of anethum graveolens (dill) powder supplementation on glycemic control, lipid profile, some antioxidants and inflammatory markers, and gastrointestinal symptoms in type 2 diabetic patients. Material and methods: In this study, 42 patients with type 2 diabetes were randomly allocated to intervention and control groups and received either 3g/day dill powder or placebo (3 capsules/day, 1 g each). Fasting blood sugar (FBS), insulin, homeostatic model assessment of insulin resistance (HOMA- IR), lipid profile, hs-C-reactive protein (hs-CRP), total antioxidant capacity (TAC), malondialdehyde (MDA), and gastrointestinal symptoms were measured in all of the subjects at baseline and post-intervention. Results: The dill powder supplementation significantly decreased the mean serum levels of insulin, HOMA-IR, LDL-C, TC, and MDA in the intervention group in comparison with the baseline measurements (p < 0.05). Also, the mean serum levels of HDL and TAC were significantly increased in the intervention group in comparison with the baseline measurement (p < 0.05). Colonic motility disorder was the only gastrointestinal symptom whose frequency was significantly reduced by supplementation (P = 0.01). The mean changes of insulin, LDL-C , TC, and MDA were significantly lower in the intervention group than in the control group (p < 0.05). In addition, the mean changes in HDL were significantly higher in the intervention group than in the control group (p < 0.05). Conclusion: Dill powder supplementation can be effective in controlling the glycemic, lipid, stress oxidative, and gastrointestinal symptoms in type 2 diabetic patients.

Background: Stroke is a common cause of morbidity and mortality worldwide, and it is the third leading cause of medical death in developed countries. Stroke can be classified into ischemic disease (80%) and hemorrhagic disease (20). Subject and methods: A case-control study done in the period extending from November 2013 to April 2014 in neuro medicine department in Azadi teaching hospital in Kirkuk city in Iraq. This study involving 2 study groups, each one of them, including 50 patients. The first group (cases) included 50 patients diagnosed as having an ischemic stroke by neurologist their ages were less than 45 years .in  another group (control), 50 patients involved admitted to the same hospital with no history of prior ischemic stroke. Results: Fifty patients with stroke of ischemic orgin and 50 controls included in the study. Table 1 summarize demographic and clinical characteristics of patients and control groups, control was older than ischemic stroke patient with no significant correlation (P-value=0.33). Gender distribution showing a significant correlation in regarding female sex in both groups (P-value=0.001). Ischemic stroke according to our findings is more prevalent in those patients with Hypertension with 66% of patients in comparison to 42% of control patients with P-value of 0.0001, diabetic patients with double percentage (72%) to those in control group (36%) with P-value of 0.0001,coronary arterial disease ,valvular heart disease and rhythm disease such as atrial fibrillation seen to be more popular  in those patients with ischemic stroke with no significant value in regarding to patients having coronary and valvular heart disease (P-value=0.11,0.21) and strongly associated with those patient presented with atrial fibrillation (P-value=0.0001). Conclusion: Elevated anticardiolipin antibodies are seen to be as an independent risk factor for ischemic stroke.

Ten control and ten diabetic subjects were first given a baseline session of no temperature biofeedback, and then were exposed to four 40-minute temperature biofeedback sessions over consecutive days. As the result of feedback training, peripheral skin temperatures increased on the training (right) hands of both groups, and this occurred to a greater extent in the diabetic group. Concomitant temperature increases occurred also in the left hands of both groups. Neither group produced any significant changes in heart rate, respiration rate, or systolic blood pressure with the exception of a significant decrease in diastolic blood pressure for the diabetic group. No difference in diastolic blood pressure was observed, however, when the diabetics were compared with the control group. The results would suggest further evaluation of temperature biofeedback training is warranted in a diabetic population as a potential means of increasing peripheral blood flow in the extremities.

1 The relationship between plasma chlorpropamide concentration and thyroid function was examined in 87 maturity onset diabetic patients receiving chronic therapy. 2 Although plasma chlorpropamide concentration was weakly negatively correlated with serum thyroxine (r= 0.33, P< 0.01) the mean serum thyroxine and thyrotrophin (TSH) were not different from that of a matched control group of diabetics treated with diet alone. 3 Serum thyroxine was negatively correlated with the duration of diabetes in both groups. 4 These results suggest that chlorpropamide does not have a clinically significant antithyroid effect.
