Background In contrast with the setting of acute myocardial infarction, there are limited data regarding the impact of diabetes mellitus on clinical outcomes in contemporary cohorts of patients with chronic coronary syndromes. We aimed to investigate the prevalence and prognostic impact of diabetes according to geographical regions and ethnicity. Methods and results CLARIFY is an observational registry of patients with chronic coronary syndromes, enrolled across 45 countries in Europe, Asia, America, Middle East, Australia, and Africa in 2009–2010, and followed up yearly for 5 years. Chronic coronary syndromes were defined by ≥1 of the following criteria: prior myocardial infarction, evidence of coronary stenosis >50%, proven symptomatic myocardial ischaemia, or prior revascularization procedure. Among 32 694 patients, 9502 (29%) had diabetes, with a regional prevalence ranging from below 20% in Northern Europe to ∼60% in the Gulf countries. In a multivariable-adjusted Cox proportional hazards model, diabetes was associated with increased risks for the primary outcome (cardiovascular death, myocardial infarction, or stroke) with an adjusted hazard ratio of 1.28 (95% confidence interval 1.18, 1.39) and for all secondary outcomes (all-cause and cardiovascular mortality, myocardial infarction, stroke, heart failure, and coronary revascularization). Differences on outcomes according to geography and ethnicity were modest. Conclusion In patients with chronic coronary syndromes, diabetes is independently associated with mortality and cardiovascular events, including heart failure, which is not accounted by demographics, prior medical history, left ventricular ejection fraction, or use of secondary prevention medication. This is observed across multiple geographic regions and ethnicities, despite marked disparities in the prevalence of diabetes. ClinicalTrials identifier ISRCTN43070564

Aim. to present the results of treatment of long bones chronic osteomyelitis using local cement reinforcing antibacterial implant. Material and methods. the implant is made intraoperatively using polymethylmethacrylate. it was used in main group (n=30), while conventional treatment was applied in comparison group (n=30). Results. Better early and remote outcomes were shown in main group including more effective and earlier suppression of infectious process, more than 2-fold decrease of recurrent infection incidence, minimization of risk of pathological fracture due to internal reinforcement, early recovery of extremity's function, creation of favorable conditions for bone structures restoration, substitution of post-resection bone defect and following organotypic reorganization of bone tissue.

Foundation. Chronic plantar fasciopathic pain syndrome is a pathology that significantly affects the quality of life of patients of all age categories. Insufficient knowledge of the etiological and pathogenetic factors in the development of fasciopathies explains the multiplicity, and sometimes inconsistency, of conservative and surgical treatment regimens. The choice of the optimal variant of therapeutic or surgical intervention may be associated with experimental modeling of fasciopathies and the study of the dynamics of the pathological process.The aim. To study the morphological changes in structures identical to the human plantar aponeurosis in experimental modeling of fasciopathy in animals.Research methods. The material for the study was fragments of the tendonaponeurotic complex of the foot of laboratory animals (control group: animals with the introduction of physiological sodium chloride solution (n = 12); main group: animals with the introduction of alprostadil (n = 12)). The methods of light microscopy (staining with alcian and toluidine blue, according to Van Gieson, Weigert – Van Gieson and Picro-Mallory) and morphometry were used.Results and discussion. As a result of the study, it was found that the four-fold administration of alprostadil had a significant effect on the structure of the dense fibrous connective tissue of the plantar foot of laboratory animals. The mechanisms of damage (edema, microhemorrhages, infiltration by lymphocytes, plasmocytes and leukocytes, dystrophy by the type of mucoid and fibrinoid swelling, delamination and rupture of collagen fibers), adaptation and regeneration (the appearance of a large number of activated fibrocytes, fibroblasts, microvessels, neoplasm of collagen fibers) were activated. All this together led to spatial focal histotopographic changes, consisting in an increase in the cellular composition of connective tissue structures against the background of a noticeable violation of their spatial orientation.Conclusion. Modeling of fasciopathy using alprostadil was accompanied by the appearance of mosaic reversible and irreversible heteromorphic and heterochronous changes in all connective tissue aponeurotic structures. Such histotopographic changes should be considered as one of the reasons for the clinical manifestations of plantar fasciopathies, causing functional insufficiency and explaining the clinical recurrent nature of the pathological process.

Degree and terms of acetabular bone structures reparation, indices of total and local immunity were evaluated in experiment (12 dogs with osteomyelitis). In the main group surgical treatment consisted of proximal femur resection with implantation of articulating spacer. In control group resection arthroplasty was performed. Roentgenologic and morphologic data showed marked reparative regeneration of acetabular bone structures under the influence of inserted spacer at terms up to 16 weeks. At application of spacers immunologic picture was characterized by rapid restoration of pro- and anti-inflammatory cytokines balance as well as by the absence of immunomodulatory effect on phagocytic link of the immune system.

Efficacy of reinforcing local antibacterial carriers use upon the degree and terms of reparative regeneration of bone tissue defects resulted from osteomyelitis process was assessed in animal experiment (36 rabbits). In study group ( n =18) surgical treatment consisted of osteomyelitis focus salvage resection and installation of reinforcing local antibacterial carrier based on polymethyl methacrylate. In control group ( n =18) radical resection of the osteomyelitis focus with adjacent soft tissue structures was performed. In study group growth of microorganisms was not detected already on 28 th postoperative day while in control group the complete depression of pathogenic microflora was achieved only by day 50. Roentgenologic and morphologic data showed marked reparative regeneration in the zone of defect with formation of functionally mature callus under the effect of antibacterial carrier at terms up to 16 weeks.
