RESUMO
Abstract The aim of this study is to provide a real picture of the disease burden of Prameha in society. The study was performed in Government Ayurved College and Hospital, Nagpur, Maharashtra during Oct 2015-Mar 2016. Total 60 patients of newly diagnosed type 2 diabetes mellitus attending the Kayachikitsa Opd of GAC Nagpur were included for the study. The subjects details were recorded in case report form. The CRF included many variables such as sociodemographic factors, presenting symptoms, risk factors such as hypertension, obesity and glycaemic status, family history of diabetes and physical activity. Other parameters like BMI, glycosylated haemoglobin, fasting and post prandial blood sugar and fasting lipid profile were documented. Descriptive and bivariate analyses were carried out using the XLSTAT software (2020). Amongst 60 subjects, 65% were male and 93.3% were adults. 78% of subjects were following sedentary lifestyle and 40% had family history of diabetes. The results revealed that, obesity, family history of diabetes, uncontrolled glycemic status, sedentary lifestyles, and hypertension were prevalent among the Prameha subjects. The characterization of this risk profile and early detection of prameha by observing poorvarupa will contribute to designing more effective and specific strategies for screening and controlling Prameha in Maharashtra, India.

INTRODUCTION: Microvascular changes in eye and kidney shares some common factors in diabetes mellitus (DM). The purpose was to evaluate choroidal thickness (CT) and choriocapillaris (CC) density in patients with type 2 diabetes (T2D) and their association with diabetic kidney disease (DKD) using swept-source optical coherence tomography (SS-OCT). RESEARCH DESIGN AND METHODS: A cross-sectional study was conducted with patients with T2D with mild or no diabetic retinopathy (DR) and non-diabetic controls. CT was measured with SS-OCT, and CC vascular density was measured with OCT angiography. These parameters were compared with inner retinal layers thickness in patients with and without DKD and non-diabetic controls. RESULTS: Ninety-three eyes from patients with T2D and 34 eyes from controls volunteers were included. Within the T2D group, 56 eyes with DKD and 37 eyes from patients with no diabetic kidney disease were examined. A statistically significant reduction of CT was observed in patients with DKD compared with controls, with no difference in CC density. There was an association between ganglion cell layer and central choroidal thickness reduction in the DKD group. CONCLUSIONS: Patients with T2D with DKD showed a decrease in CT with no difference in CC density compared with non-diabetic controls. This thinning might be related to vascular changes of choroidal layers such as Haller's and Sattler's with preservation of CC density, which is crucial for outer retina and retinal pigment epithelium health. Longitudinal studies are warranted to determine the association of choroidal changes with the pathogenesis of diabetes, and its association with early DKD and progression to more severe DR.

OBJECTIVE: This study aimed to analyze the kidneys among the subjects with early stages of type 2 diabetic kidney disease by shear wave elastography quantitatively. METHODS: A total of 108 patients with type 2 diabetic kidney disease and 17 control subjects were enrolled. According to the estimated glomerular filtration rate and urinary albumin-to-urinary creatinine ratio, patients were classified into stages 1 to 3 diabetic kidney disease. Grayscale ultrasound andshear wave elastography were performed. The sizes, depths, and shear wave elastography values were recorded. These parameters were compared between the diabetic kidney disease and the control subjects. RESULTS: The mean shear wave elastography values were significantly higher in the diabetic kidney disease group (10.156±1.75 kPa vs. 8.241±1.4 kPa; p<0.001). We obtained statistically significantly higher shear wave elastography values in stages 2 and 3 diabetic kidney disease subjects than control subjects and in patients with stage 3 diabetic kidney disease compared to those with stage 1 diabetic kidney disease (p<0.05 for all). We obtained a cutoff value of 9.23 kPa for predicting diabetic kidney disease in early stages, with a sensitivity of 67% and a specificity of 82%. CONCLUSION: Shear wave elastography may be used as a noninvasive, simple, and quantitative method to provide diagnostic information as a part of routine management of patients with type 2 diabetes mellitus, especially in the early stages of diabetic kidney disease.

We report a methodology to analyze data extracted from infrared images. These pictures show the lower limbs of a cohort of individuals belonging to, (1) voluntary controls and (2) patients diagnosed with diabetes mellitus type II. The analysis is presented in terms of Cross Entropy and temperature distributions; both using the associated thermal histograms. The temperature analysis is placed in terms of comparing the extreme values ofdS/dQ, for controls and patients. In this analysis for the frontal view, the values of specificity and sensitivity calculated were 77.77% and 91.66%, respectively. For the back view, the specificity and sensitivity obtained were 88.8% and 83.3%, respectively. Instead of that, the cross-entropy analysis is placed in the modality of self-referencing. In this part of the study we obtained the coefficient of asymmetry and thermal response (ATR). The values of specificity and sensitivity for the ATR quotient in both cases were 83.3%. The results of both studies have a significant correlation with glucose (p< 0.01) and HbA1c (p< 0.01). It means that both approaches have statistical correspondence. By means of the Mann-Whitney U test, for independent samples, we get that the characteristic parameters we analyze can be differentiated among the populations of interest with a significance ofp< 0.05. This suggests that both studies show consistency with the clinical diagnosis; exhibiting clear differences between control and patient groups.

ABSTRACT Purpose: To describe microvascular changes in the maculas of individuals with type 2 diabetes observed on optical coherence tomography angiography (OCTA) images. We compared the maculas of diabetic subjects without diabetic retinopathy with those of healthy subjects and correlated the findings with the clinical profiles of diabetic subjects. Methods: One eye each of 30 patients with diabetes and 30 healthy individuals were examined. The patients with diabetes underwent funduscopy, retinography, and fluorescein angiography to rule out retinopathy. All subjects underwent optical coherence tomography angiography of a macular area (6×6 mm2), and the foveal and parafoveal vascular densities were analyzed in the superficial and deep retinal vascular plexus. The foveal and parafoveal thicknesses, foveal avascular zone of the superficial plexus, and choriocapillaris flow area were also examined. The optical coherence tomography angiography results were compared between the two study groups and correlated with the following parameters: visual acuity, time since diabetes diagnosis, glycemic control, lipid profile, and renal function of patients with diabetes. Results: A minimal increase in the choriocapillaris flow area was observed in the patients with diabetes (mean area, 22.3 ± 4.6 mm2 in controls; 22.6 ± 3.9 mm2 in patients with diabetes) (p=0.017). No significant differences were observed between other optical coherence tomography angiography parameters analyzed in the two groups. Glycosylated hemoglobin and fasting blood glucose levels were significantly negatively correlated with the foveal vascular density of both plexuses; conversely, fasting blood glucose levels were positively correlated with the choriocapillaris flow area (p=0.034). The other clinical parameters were not correlated with the optical coherence tomography angiography findings. Conclusion: Optical coherence tomography angiography may not be the most appropriate tool for detecting preclinical changes in patients with diabetes, moreover, optical coherence tomography angiography; does not replace clinical examinations. Glycemic control should be the primary clinical parameter considered during retinopathy screening. Larger studies are necessary to confirm these findings.
RESUMO Objetivo: Descrever alterações microvasculares na mácula em diabéticos do tipo 2 sem retinopatia diabética e pacientes saudáveis, e correlacionar achados com perfil clínico nos diabéticos. Métodos: Foram incluídos 60 olhos de 30 diabéticos e 30 pacientes saudáveis. Diabéticos realizaram fundoscopia, retinografia® (CR2; Canon Inc., New York, New York, USA) e angiografia fluoresceínica® (TRC-50DXC; Topcon Inc., Tokyo, Japan) para descartar a presença de retinopatia. Os 60 pacientes realizaram a angiografia por tomografia de coerência óptica® (RTVue XR, Avanti, Optovue, Fremont, CA, USA) (área macular: 6 x 6 mm2) e foram analisados densidade vascular total, foveal e parafoveal no plexo capilar superficial e plexo capilar profundo, espessura foveal, espessura parafoveal, área da zona avascular da fóvea no plexo capilar superficial e área de fluxo da coriocapilar. Resultados da angiografia por tomografia de coerência óptica foram comparados entre os 2 grupos e correlacionados com acuidade visual, tempo de diabetes, controle glicêmico, perfil lipídico e função renal nos diabéticos. Resultados: Observou-se aumento mínimo da área de fluxo da coriocapilar nos diabéticos, média das áreas foi de 22,3 ± 4,6 mm2 no grupo controle e 22,6 ± 3,9 mm2 em diabéticos (p=0,017). Não foi observada diferença estatisticamente significante entre outras variáveis da angiografia por tomografia de coerência óptica analisadas nos dois grupos. Hemoglobina glicosilada e glicemia de jejum apresentaram correlação negativa estatisticamente significante com densidade vascular foveal de ambos os plexos e a glicemia de jejum se correlacionou positivamente com área de fluxo da coriocapilar (p=0,034). Outros dados clínicos avaliados não apresentaram correlação com achados da angiografia por tomografia de coerência óptica. Conclusão: Resultados sugerem que a angiografia por tomografia de coerência óptica pode não ser a melhor ferramenta na detecção de alterações pré-clínicas em diabéticos, não substituindo o exame clínico, e corroboram a ideia de que o controle glicêmico deve ser o principal parâmetro clínico a ser considerado na triagem da retinopatia. Estudos com amostras maiores são necessários para confirmar os achados.

INTRODUCTION AND OBJECTIVES: Noninvasive liver assessment in type 2 diabetes (T2DM) in a primary care population identifies higher risk non-alcoholic fatty liver disease (NAFLD). We aimed to evaluate the association of T2DM with liver fibrosis and steatosis by transient elastography (TE). MATERIALS AND METHODS: This is a retrospective study of a TE referral program where primary care physicians were able to order TE. Patients with alcohol abuse were excluded. TE and Controlled Attenuation Parameter (CAP) scores were obtained. Multivariable linear and logistic regression models were used to adjust for confounders. RESULTS: 28% had T2DM. The mean TE score in T2DM patients was 8.3 (±6) kilopascal (kPa) and 6.4 (±3.7) kPa in those without T2DM (p = 0.0001). Those with T2DM had a higher CAP (322 ± 51 dB/m vs. 296 ± 57 dB/m, p < 0.0001). In multivariable analysis, T2DM was associated with TE score (ß: 1.9, 95% confidence interval [CI]: 0.74-3.1, p = 0.001) and CAP (ß: 2.8, 95% CI: 9.3-36.2, p = 0.001). Patients with T2DM had higher-risk TE scores and more steatosis by CAP. CONCLUSION: T2DM is associated with liver fibrosis and steatosis by TE within a primary care population. A TE referral pathway may be utilized for T2DM patients who are at higher risk of NAFLD and its complications.

Epicardial fat thickness (EFT) is associated with aortic stiffness in diabetic patients. In this study, we aimed to determine if there is an association among the parameters of EFT, aortic velocity propagation (AVP), and carotid intima-media thickness (CIMT) in patients with non-insulin dependent diabetes mellitus. This study included 55 non-insulin dependent diabetes mellitus patients and 40 non-diabetic control patients. For all participants, EFT and AVP were determined by echocardiographic method and CIMT was calculated using an ultrasonographic exam. The EFT and CIMT values were found to be significantly increased in the non-insulin dependent diabetes mellitus group. On the other hand, aortic velocity propagation was decreased in the non-insulin dependent diabetes mellitus group compared to non-diabetic patients (EFT; 8.43 ± 1.68 versus 6.36 ± 2.21 mm, p < 0.001; CIMT; 0.92 ± 0.24 versus 0.58 ± 0.18 mm, p < 0.001; and AVP; 28.20 ± 16.02 versus 58.10 ± 17.50, p < 0.01, respectively). Significantly higher EFT and CIMT values were found in addition to lower AVP values in non-insulin dependent diabetes mellitus patients. Moreover, we demonstrated that there was a strong correlation between EFT, CIMT, and AVP.

Diabetic nephropathy (DN) is a multifactorial disease characterized by hyperglycemia and close interaction of hemodynamic, metabolic and inflammatory factors. Nuclear factor-κB (NF-κB) is a principal matchmaker linking hyperglycemia and inflammation. The present work investigates the cell-permeable peptide containing the inhibitor of kappa B kinase γ (IKKγ)/NF-κB essential modulator (NEMO)-binding domain (NBD) as therapeutic option to modulate inflammation in a preclinical model of type 2 diabetes (T2D) with DN. Black and tan, brachyuric obese/obese mice were randomized into 4 interventions groups: Active NBD peptide (10 and 6 µg/g body weight); Inactive mutant peptide (10 µg/g); and vehicle control. In vivo/ex vivo fluorescence imaging revealed efficient delivery of NBD peptide, systemic biodistribution and selective renal metabolization. In vivo administration of active NBD peptide improved albuminuria (>40% reduction on average) and kidney damage, decreased podocyte loss and basement membrane thickness, and modulated the expression of proinflammatory and oxidative stress markers. In vitro, NBD blocked IKK-mediated NF-κB induction and target gene expression in mesangial cells exposed to diabetic-like milieu. These results constitute the first nephroprotective effect of NBD peptide in a T2D mouse model that recapitulates the kidney lesions observed in DN patients. Targeting IKK-dependent NF-κB activation could be a therapeutic strategy to combat kidney inflammation in DN.
