Biodegradable polymer-coated thin strut sirolimus- -eluting stent versus durable polymer-coated everolimus-eluting stent in the diabetic population.
2021
Background: The number of patients with diabetes mellitus (DM) presenting with coronary artery disease is increasing and accounts for more than 30% of patients undergoing percutaneous coronary interventions (PCI). The biodegradable polymer drug-eluting stents were developed to improve vascular healing. It was sought herein, to determine 1-year clinical follow-up in patients with DM treated with the thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus durable coating everolimus-eluting stent (DP-EES). Methods: Patients were retrospectively analyzed with DM were treated with either a BP-SES (ALEX™, Balton, Poland, n = 670) or a DP-EES (XIENCE™, Abbott, USA, n = 884)…
Transitional cell carcinoma of the renal pelvis presenting as a renal abscess.
2002
We report on a 76-year-old woman who was diagnosed with a primary renal abscess of the left kidney. After percutaneous drainage, no clinical improvement was observed. Surgical exploration and nephrectomy were performed. The histologic evaluation revealed an unsuspected transitional cell carcinoma of the renal pelvis, which had been misinterpreted as a primary renal abscess. Malignancy must be considered as an underlying cause for the formation of a renal abscess, especially if no other predisposing factors such as diabetes mellitus or urinary stones are present.
Coronary artery bypass graft versus percutaneous coronary intervention with drug-eluting stent implantation for diabetic patients with unprotected le…
2013
textabstractAims: Data regarding the impact on clinical outcomes of PCI with DES implantation vs. CABG to treat unprotected left main coronary artery (ULMCA) disease in diabetic patients are still insufficient. The present study evaluated the short-term and long-term results of percutaneous and surgical revascularisation in diabetic patients with ULMCA disease in a large population. Methods and results: A total of 826 diabetic patients with ULMCA stenosis who received DES (n=520) or underwent CABG (n=306) were selected and analysed from the DELTA registry. In-hospital MACCE was significantly higher in the CABG group, mainly driven by a higher incidence of MI. At four-year follow-up, freedom…
The Assessment of General Health Status in Patients with Odonto-Periodontal Pathology and Diabetes Mellitus
2021
Abstract The present research attempts to assess the general health status of the studied group of patients by applying the questionnaire method. The research group has been composed of 210 subjects, from both urban and rural areas, having periodontal pathologies and disorders of the glucidic metabolism. In order to obtain information about the general health condition as well as the orodental hygiene, we have applied the questionnaire method, this being well individualized and adapted to be relevant to the present study. It was highlighted that patients with odonto-periodontal pathology and diabetes gave a more affected general health compared to those without diabetes.
The HIF1α-PFKFB3 Pathway: A Key Player in Diabetic Retinopathy
2021
Abstract Diabetic retinopathy (DR) is the leading cause of blindness for adults in developed countries. Both microvasculopathy and neurodegeneration are implicated in mechanisms of DR development, with neuronal impairment preceding microvascular abnormalities, which is often underappreciated in the clinic. Most current therapeutic strategies, including anti-vascular endothelial growth factor (anti-VEGF)-antibodies, aim at treating the advanced stages (diabetic macular edema and proliferative diabetic retinopathy) and fail to target the neuronal deterioration. Hence, new therapeutic approach(es) intended to address both vascular and neuronal impairment are urgently needed. The hypoxia-induci…
Rheological and metabolic leucocyte determinants in diabetes mellitus
1995
In diabetics of type I and 2 we examined, in resting white blood cells (WBC), the filtration parameters (Initial Relative Flow Rate - lRFR, Clogging Rate - CR) employing the St. George Filtrometer, the polymorphonuclear cells (PMN) membrane fluidity, the PMN cytosolic Ca2+ content and the PMN membrane cholesterol/phospholipid ratio (C/PL). From the obtained data, it is evident that, while the lRFR of unfractionated WBC distinguishes normals from diabetics of type 1 and 2, the fIltration parameters of the PMN and mononuclear cells (MN) do not show any significant difference. PMN membrane fluidity, PMN cytosolic Ca2+ content and PMN C/PL do not discriminate normals from diabetics of type 1 an…
Pharmacological comparison of rat and human melanocortin 3 and 4 receptors in vitro.
2002
Abstract The melanocortin 3 and 4 receptors are G-protein-coupled receptors found in the hypothalamus with important role in regulation of the energy balance. In this study, we performed pharmacological comparison of the rat and human melancortin (MC) 3 and MC4 receptors. We transiently expressed the genes for these receptors individually in a mammalian cell line and determined the binding affinities to several MSH peptides. The results showed no major difference between the rat and human MC3 receptors while the rat MC4 receptor had higher affinity to several peptides compared with the human MC4 receptor. NDP-, α-, β-, γ-MSH, ACTH(1–24), HS014 and MTII had from 5- to 34-fold higher affinity…
Is Myeloperoxidase a Key Component in the ROS-Induced Vascular Damage Related to Nephropathy in Type 2 Diabetes?
2013
AbstractIt is still unclear whether microvascular complications of type 2 diabetes correlate with leukocyte-endothelium interactions and/or myeloperoxidase (MPO) levels. In the present study, we found that serum levels of glucose, the rate of ROS and MPO concentration were higher in type 2 diabetic patients. Patients with nephropathy (39.6%) presented higher MPO levels that correlate positively with the albumin/creatinine ratio (r=0.59, p<0.05). In addition, nephropatic patients showed increased leukocyte-endothelium interactions due to an undermining of polymorphonuclear leukocytes (PMN) rolling velocity and increased rolling flux and adhesion, which was accompanied by a rise in levels of …
Electrical responses of homing pigeon and guinea pig Purkinje cells to pineal indoleamines applied by microelectrophoresis
1984
The effects of microelectrophoretically applied melatonin (aMT), 5-methoxytryptophol (ML), 5-hydroxytryptophol (HL) and noradrenaline (NA) on the electrical activity of cerebellar Purkinje and other cells during both day- and nighttime were studied in urethane-anesthetized intact and pinealectomized homing pigeons and guinea pigs.
