Fibronectin (FN) may be involved in time- and stage-dependent and inter-related controlled processes of inflammation, coagulation, and wound healing accompanying peripheral arterial disease (PAD). In the present study, FN and FN-containing extra-domain A (EDA-FN), macromolecular FN-fibrin complexes, and FN monomer were analysed in the plasma of 142 PAD patients, including 37 patients with restenosis, for 37 months after revascularisation. FN concentration increased significantly in the plasma of PAD patients within 7 to 12 months after revascularisation, whereas the high concentration of EDA-FN was maintained up to 24 months, significantly higher in the group 7 to 12 months after revascularisation with recurrence of stenosis and lower in the PAD groups 1 to 3 months and 4 to 6 months after revascularisation with comorbid diabetes and ulceration, respectively...

Background: Relatively little is known about the role of phosphatidylserine (PS) in procoagulant activity (PCA) in patients with diabetic kidney disease (DKD). This study was designed to evaluate whether exposed PS on microparticles (MPs) and MP-origin cells were involved in the hypercoagulability in DKD patients. Methods: DKD patients (n = 90) were divided into three groups based on urinary albumin excretion rate, defined as normoalbuminuria (No-A) (<30 mg/24 h), microalbuminuria (Mi-A) (30-299 mg/24 h) or macroalbuminuria (Ma-A) (>300 mg/24 h), and compared with healthy controls (n = 30)...

It would be important to predict type 2 diabetes mellitus (T2DM) and diabetic nephropathy (DN). This study was aimed at evaluating the predicting significance of hemostatic parameters for T2DM and DN. Plasma coagulation and hematologic parameters before treatment were measured in 297 T2DM patients. The risk factors and their predicting power were evaluated. T2DM patients without complications exhibited significantly different activated partial thromboplastin time (aPTT), platelet (PLT), and D-dimer (D-D) levels compared with controls ( P < 0...

Congenital disorders of glycosylation (CDG) and mitochondrial disorders have overlapping clinical features, including central nervous system, cardiac, gastrointestinal, hepatic, muscular, endocrine, and psychiatric disease. Specific abnormalities orienting the clinician toward the right diagnostic approach include abnormal fat distribution, coagulation abnormalities, together with anticoagulation abnormalities, hyperinsulinism, and congenital malformations in CDG. Diabetes, sensorineural deafness, and depression are very rare in CDG but common in mitochondrial disease...

Background: Inflammation and oxidative stress are important factors associated with chronic disease such as essential hypertension (HTN) and type 2 diabetes mellitus (T2DM). However, the association of inflammation and oxidative stress in HTN with T2DM as a comorbidity is inconclusive due to the multifactorial nature of these cardiometabolic diseases. Methodology: The influence of pathophysiological factors include genetics, age of patient, and disease progression change throughout the lifespan and require further investigation...

Methionine aminopeptidase 2 (MetAP2) inhibition is a promising approach to treating diabetes, obesity, and associated metabolic disorders. Beloranib, a MetAP2 inhibitor previously investigated for treatment of Prader-Willi syndrome, was associated with venous thrombotic adverse events likely resulting from drug effects on vascular endothelial cells (ECs). Here, we report the pharmacological characterization of ZGN-1061, a novel MetAP2 inhibitor being investigated for treatment of diabetes and obesity. Four weeks of subcutaneous administration of ZGN-1061 to diet-induced obese (DIO) insulin-resistant mice produced a 25% reduction in body weight, primarily due to reduced fat mass, that was comparable to beloranib...

Type 2 diabetes mellitus (T2DM) is characterised not only by hyperglycaemia and insulin resistance but also an impaired balance between the processes of coagulation and fibrinolysis. The aim of this study was to examine the effects of metformin, a widely-used oral anti-diabetic drug, phenformin and eight sulfenamide and sulfonamide derivatives of metformin on several haemostasis parameters. Thrombin Time (TT) tests were performed according to the available commercial method. The activity of factor X was conducted based on deficient plasma factor X...

Surgery for craniopharyngiomas can be challenging due to the involvement of multiple critical neurovascular structures. The expanded endoscopic endonasal approach can provide superior access to suprasellar craniopharyngiomas, particularly with retrochiasmatic extension and significant hypothalamic involvement. We describe the surgical technique used to treat a 30-year-old patient who presented with 4 weeks of worsening vision, fatigue, and memory loss. His vision was counting fingers at 1 feet on the right and 20/800 on the left with a temporal hemianopsia...

Pregnancy leads to significant changes in the body, which potentially affect the retina. Pregnancy can induce disease, such as that seen in hypertensive retinopathy and choroidopathy. It can cause exudative retinal detachments in the HELLP syndrome (hemolysis, elevated liver enzymes and low platelets), disseminated intravascular coagulation (DIC), and thrombotic thrombocytopenic purpura (TTP), and provoke arterial and venous retinal occlusive disease. Pregnancy may also exacerbate pre-existing retinal disease, such as idiopathic central serous chorioretinopathy (ICSC) and diabetic retinopathy...

There is a strong association between a suboptimal maternal environment and increased risk of developing age-associated diseases such as type 2 diabetes, obesity, and cardiovascular disease in the offspring. Blood clotting time may be altered in all of these conditions, and it is also an important factor that requires monitoring in postoperative and cardiovascular disorder patients who are on coagulant medications. This chapter describes patient self-management of blood coagulation activity using a test strip device and the Coagu app...

Although platelet-rich plasma (PRP) is used as a source of growth factors in regenerative medicine, its effectiveness remains controversial, partially due to the absence of PRP preparation protocols based on the regenerative role of platelets. Here, we aimed to optimise the protocol by analysing PRP angiogenic and regenerative properties. Three optimising strategies were evaluated: dilution, 4 °C pre-incubation, and plasma cryoprecipitate supplementation. Following coagulation, PRP releasates (PRPr) were used to induce angiogenesis in vitro (HMEC-1 proliferation, migration, and tubule formation) and in vivo (chorioallantoic membrane), as well as regeneration of excisional wounds on mouse skin...

BACKGROUND: Type 2 diabetes mellitus (T2DM) is associated with chronic lowgrade inflammation. Microparticles (MPs) are extracellular microvesicles released during apoptosis and cellular activation. The MP's pro-coagulant and pro-inflammatory activities are involved in endothelial dysfunction observed in T2DM patients. This study aimed to evaluate the circulating MPs profile in T2DM patients with diabetic kidney disease (DKD) and correlate it with clinical and laboratorial parameters. METHODS: MPs derived from platelets (PMPs), leukocytes (LMPs), endothelial cells (EMPs), and expressing tissue factor (TFMPs) were measured by flow cytometry, in plasma of 39 DKD patients and 30 non-diabetic controls...

Wound care is a major healthcare expenditure. Treatment of burns, surgical and trauma wounds, diabetic lower limb ulcers and skin wounds is a major medical challenge with current therapies largely focused on supportive care measures. Successful wound repair requires a series of tightly coordinated steps including coagulation, inflammation, angiogenesis, new tissue formation and extracellular matrix remodelling. Zinc is an essential trace element (micronutrient) which plays important roles in human physiology...

BACKGROUND: Metabolic syndrome (MetS) is a highly prevalent condition that identifies individuals at risk for type 2 diabetes mellitus and atherosclerotic cardiovascular disease. Prevention of these diseases relies on early detection and intervention in order to preserve pancreatic β-cells and arterial wall integrity. Yet, the clinical criteria for MetS are insensitive to the early-stage insulin resistance, inflammation, cholesterol and clotting factor abnormalities that characterize the progression toward type 2 diabetes and atherosclerosis...

Although oxidization of LDL is known to be a crucial step for atherosclerotic progression, the significance of oxidized HDL remains to be clarified. The purpose of this study was to determine the relationships of oxidized HDL with blood coagulation and fibrinolysis in patients with diabetes. The subjects were outpatients with type 2 diabetes (n = 163; median hemoglobin A1c, 6.9%). Activities of blood coagulation and fibrinolysis were evaluated by levels of thrombin-anti-thrombin complex (TAT) and plasmin-α2 plasmin inhibitor complex (PIC), respectively...

BACKGROUND: Exacerbated immunopathology is a frequent consequence of TB that is complicated by diabetes mellitus (DM); however, the underlying mechanisms are still poorly defined. METHODS: In the two groups of age- and sex-matched patients with TB and DM (DM-TB) and with TB and without DM, we microscopically evaluated the areas of caseous necrosis and graded the extent of perinecrotic fibrosis in lung biopsies from the sputum smear-negative (SN) patients. We scored acid-fast bacilli in sputum smear-positive (SP) patients and compiled CT scan data from both the SN and SP patients...

BACKGROUND: Spontaneous cervical artery dissections (sCAD) are often preceded by infections. However, existing data about inflammatory parameters remained inconsistent. Remarkably, concurrent information about the coagulation system, whose affection seems also reasonable to cause ischaemic events, are still lacking in sCAD patients. Thus, this study explores the association between the inflammatory and coagulation system in patients with sCAD. METHODS: The parameters leukocyte and thrombocyte count, C-reactive protein, fibrinogen, D-dimer, activated partial thromboplastin time (aPTT) and prothrombin time were extracted from hospital-based medical records of patients (n = 60) with sCAD and compared with those of a control group (n = 97) from a prospective observational stroke study...
