OBJECTIVE Microvascular decompression (MVD) is regarded as a valid treatment modality in neurovascular conflicts (NVCs) causing, for example, trigeminal neuralgia and hemifacial spasms. An NVC of the cochleovestibular nerve might cause tinnitus and/or vertigo; however, general acceptance of MVD for this indication is lacking. The aim of this study was to investigate the effectiveness, safety, and prognostic factors for success of MVD of the cochleovestibular nerve. METHODS A systematic review and meta-analysis of individual patient data (IPD) were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Individual Patient Data (PRISMA-IPD) guidelines...

The retinal microvascular damage is a complication of diabetic retinopathy (DR). Hyperglycemia and hypoxia are responsible of aberrant vessel's proliferation. The cellular response to hypoxia is mediated through activation of hypoxia-inducible factors (HIFs). Among these, HIF-1α modulates expression of its target gene, VEGF, whose upregulation controls the angiogenic event during DR development. In a previous study, we have demonstrated that a small peptide, NAP, is able to protect retina from hyperglycemic insult...

REVIEW
M Odette Gore, Darren K McGuire
Measurement of glycated hemoglobin (HbA1c), the most widely accepted indicator of long-term glycemic exposure, is central for the diagnosis and management of diabetes mellitus. Levels of HbA1c track epidemiologically with diabetic complications, and glycemic control, as reflected by HbA1c reduction, results in decreased risk of microvascular complications, including diabetic kidney disease, neuropathy, and retinopathy. The relationship between HbA1c reduction and cardiovascular disease prevention in patients with diabetes is more complex, with data from large randomized trials published over the past decade providing clear evidence that lowering of HbA1c per se is an inadequate marker for a therapeutic regimen's impact on cardiovascular outcomes and patient survival...

Hypoglycemia is the major barrier for optimal glycemic control in patients on maintenance insulin therapy. It is widely known that good glycemic control leads to prevention of or delay in the development of microvascular complications, and can reduce macrovascular events. It is thought that hypoglycemia may predispose patients to cognitive deterioration and may negatively affect the cardiovascular system. Hypoglycemia per se can contribute to a blunted counterregulatory response and disabling hypoglycemia, while hypoglycemia avoidance restores normal response to low blood glucose levels...

Diabetic nephropathy (DN) is a serious complication of diabetes mellitus, and its prevalence has been increasing in developed countries. Diabetic nephropathy has become the most common single cause of end-stage renal disease worldwide. Oxidative stress and inflammation factors are hypothesized to play a role in the development of late diabetes complications. Chronic hyperglycemia increases oxidative stress, significantly modifies the structure and function of proteins and lipids, and induces glycoxidation and peroxidation...

BACKGROUND: Demographic change implies that the human population is getting older and the elderly are living longer. Consequently, achieving good functional and aesthetic outcomes in microvascular procedures, especially in very old patients with higher incidence of atherosclerosis and vessel calcifications, constitutes a microsurgical challenge. This study evaluates the feasibility of microsurgical procedures in a very old patient cohort. PATIENTS AND METHODS: Between 2009 and 2015, 754 patients underwent 838 free flap reconstructions...

BACKGROUND: Microvascular free tissue transfer has become the main technique used for head and neck reconstruction. We assessed the cost-effectiveness of free flap reconstruction for head and neck defects after oncologic resection for squamous cell carcinoma (SCC). METHODS: We developed a Markov model of the cost, quality of life, survival, and incremental cost-effectiveness of reconstruction with free tissue transfer compared with locoregional flaps. Health state probabilities and quality of life scores were determined from literature...

BACKGROUND: Whether type 2 diabetes mellitus (DM) in the absence of hypertension (HTA) and coronary artery disease (CAD) affects left ventricular (LV) phenotype and function among asymptomatic DM patients that can be easily discovered in everyday practice, what is the clinical risk profile for diabetic cardiomyopathy and how HTA and CAD modulate LV structure and function above diabetic cardiomyopathy, are still incompletely answered questions. METHODS: In 210 DM patients (group I: 70 asymptomatic DM patients without HTA and CAD; group II: 70 DM patients with HTA and no CAD; group III: 70 DM patients with CAD and no HTA) and 80 healthy individuals, comprehensive echocardiography including speckle tracking strain and strain rate analysis, was done...

Diabetic nephropathy (DN) is one of the most serious microvascular complications of diabetes mellitus and the leading cause of end stage renal disease. One of the key pathways activated in DN is the polyol pathway, in which glucose is converted to sorbitol (a relatively non-metabolizable sugar) by the enzyme aldose reductase (AR). Shunting of glucose into this pathway causes disruption to glucose metabolism and subsequently damages the tissues via increased oxidative stress, protein kinase c activation and production of advanced glycation end products (AGE) in the kidney...

BACKGROUND: Delayed development of intracranial aneurysms is an extremely rare complication of gamma knife surgery (GKS), and so far only 6 cases have been reported. Furthermore, there are no reported cases after GKS for trigeminal neuralgia (TN). Of the above cases, none referred to the natural history or pathophysiology of GKS-related intracranial aneurysm formation. CASE DESCRIPTION: We treated 2 patients who suffered subarachnoid hemorrhage (SAH) due to ruptures of intracranial aneurysms that developed long after GKS...

INTRODUCTION AND AIM: Endothelial microparticles (EMPs) are membrane-coated vesicles shed from endothelial cells and are considered markers of the endothelial state. It has been shown that total numbers of circulating EMPs are increased in patients with systemic sclerosis (SSc), but their clinical correlations have not yet been investigated in detail. We aimed to assess possible relationships between circulating EMPs and clinical as well as laboratory features among SSc patients with special attention to possible association with alteration in microvascular morphology objectified on nailfold videocapillaroscopy and clinical signs of microvascular complications...

Diabetic nephropathy is one of the major microvascular complications of diabetes mellitus which ultimately gives rise to cardiovascular diseases. Oxidative stress produced by prolonged hyperglycaemia and chronic renal inflammation are the two key players in the development and progression of diabetic nephropathy. NF-kB-mediated inflammatory cascade is a strong contributor to the renovascular inflammation in diabetic nephropathy. Here, we studied the effects of piceatannol, a potent NF-kB inhibitor, on various oxidative stress markers and diabetic renal inflammatory pathway in rat induced by alloxan...

Radiation-induced brain injury (RBI) is the most serious complication after radiotherapy. However, the etiology of RBI remains elusive. In order to evaluate the effect of X-rays on normal brain tissue, adult male BALB/C mice were subjected to whole-brain exposure with a single dose of 10 Gy or sham radiation. The structure and number of mice brain vessels were investigated 1, 7, 30, 90 and 180 days after irradiation by H&E staining and immune-fluorescence staining. Compared with sham control mice, in addition to morphological changes, a significant reduction of microvascular density was detected in irradiated mice brains...

BACKGROUND: Smoking is associated with increased macrovascular and microvascular complications in people with diabetes. In addition to other concomitant vascular perturbations, it also seems to influence the cardiometabolic parameters, which may partly explain the accelerated rate of vascular complications in smokers with diabetes. While smoking cessation is advocated as a universal component of the management of diabetes, there is some anecdotal evidence that HbA1c could increase following smoking cessation...

The submental island flap is useful as an alternative to microvascular free tissue transfer for the reconstruction of defects after resection of oral cancer because it is simple to harvest, reliable, and is associated with good oral function and low morbidity. However, because cancer of the oral cavity carries a risk of level I nodal metastases, the oncological safety of the flap remains controversial. Between April 2012 and September 2016, we studied patients with squamous cell carcinoma of the oral cavity who underwent surgical resection with submental island flap reconstruction for viability of the flap, signs of recurrence, and complications...

Islet endothelial cells produce paracrine factors that support β-cell function and growth. Endothelial dysfunction underlies diabetic microvascular complications; thus we hypothesized that in diabetes, islet endothelial cells become dysfunctional and this may contribute to β-cell secretory dysfunction. Islets/islet endothelial cells were isolated from diabetic db/db mice, treated with or without the glucose-lowering agent phlorizin, or C57BL/6J mice fed a high fat diet for 18 weeks (and appropriate controls)...
