Background: Antiphospholipid antibodies (aPL) have a multifaceted effect on the hemostatic system, damaging all its protective links. Aim: To study the effect of APA on outcomes of assisted reproductive technologies (ART). Study design: We examined 267 women with infertility, who planned pregnancy using ART. They included 178 women with IVF failure (I group) and 89 women with pregnancy after the IVF program (II group). The comparison group consisted of 80 pregnant women after IVF (male factor); a control group included 80 pregnant women with physiological pregnancy. Results of study demonstrated a high frequency of aPL circulation in a group of women with IVF failures. Overall, the proportion of aPL among all 267 women who planned pregnancy with ART was 32.6%. Elevated levels of aPL in the structure of causes of IVF failures (group I) were observed in 42.1% of them. Among women whose pregnancy occurred with ART (II group) the rate of APA was 19.1%. In the comparison group, in 6.3% of cases, aPL circulation was observed. In the control group, the rate was 3.4%. Conclusion: Considering the high percentage of aPL circulation in the case of IVF failures, authors think that high titers of aPL are a temporary contraindication for IVF. Patients with a history of aPL circulation are required to receive anticoagulant therapy from the first days of the hormonal protocol. The drug of choice is a group of low molecular weight heparins (LMWH). An individual approach is extremely important with the possible identification of causes of IVF failures and selective therapy, which leads to a significant improvement in the outcomes of the IVF program.

© 2019 The Author(s). Background: Spontaneous pregnancy loss and implantation failure after assisted reproductive technologies (ART) are very common occurrences. Although 50-60% of all cases remains unexplained, various predisposing factors, including thrombophilias, have been identified. Thus, the potential benefit of a prophylaxis with low-molecular-weight heparins in improving outcomes has been often investigated over the years. However, the majority of studies are observational and results from randomized clinical trials (RCTs) are inconclusive, probably due to heterogeneity and limited sample size. To cover these unmet needs and to have further data mainly based on the real-life clinical management, we designed these multicenter registries. Methods: OTTILIA (Observational sTudy on antiThrombotic prevention in thrombophILIA and pregnancy loss) and FIRST (recurrent Failures in assIsted Reproductive Techniques) registries are two prospective, multicenter, observational studies to evaluate pregnancy or ART outcomes in consecutive women with previous reproductive failures after spontaneous or assisted conception, respectively. All enrolled women are observed from their first visit after positive pregnancy test (OTTILIA) or before commencing a new ART cycle (FIRST) until the end of pregnancy or ART procedure (negative pregnancy test/end of pregnancy, if successful cycle), respectively. Data are collected by means of questionnaires and recorded in a central database. Follow-up investigations are performed during hospital stay, routine clinical follow-up visits or telephone interviews. Primary outcome is live birth rate in the OTTILIA register and clinical pregnancy rate in the FIRST. Discussion: Although RCTs are the 'gold standard' for evaluating treatment outcomes, we believe that our registries represent a valid alternative in improving knowledge on mechanisms involved in reproductive failures and supporting future clinical decisions. Trial registration: NCT 02385461, retrospectively registered 5 March 2015 (OTTILIA); NCT 02685800, registered 10 February 2016 (FIRST).

Articular hyaline cartilage is extensively hydrated, but it is neither innervated nor vascularized, and its low cell density allows only extremely limited self-renewal. Most clinical and research efforts currently focus on the restoration of cartilage damaged in connection with osteoarthritis or trauma. Here, we discuss current clinical approaches for repairing cartilage, as well as research approaches which are currently developing, and those under translation into clinical practice. We also describe potential future directions in this area, including tissue engineering based on scaffolding and/or stem cells as well as a combination of gene and cell therapy. Particular focus is placed on cell-based approaches and the potential of recently characterized chondro-progenitors; progress with induced pluripotent stem cells is also discussed. In this context, we also consider the ability of different types of stem cell to restore hyaline cartilage and the importance of mimicking the environment in vivo during cell expansion and differentiation into mature chondrocytes.

Objective: The article studies state-of-the art physical therapeutic techniques as a high degree of relevance to minimize invalidation and improve quality of life for patients with dental osteosarcoma. Materials and Methods: A randomized controlled clinical trial was conducted in 21 patients with osteogenic sarcoma of mandible (C41.1). There were 10 patients in the experimental group and 11 patients in the control group. Results: A comprehensive treatment and rehabilitation program for patients with osteosarcoma of mandible was developed. The first part of the program comprised 3 basic phases: preop chemotherapy, surgery, and postop rehabilitation. The surgical treatment further included resection of an affected part of the mandible and primary repair of the defect with jaw fragments and an autoimplant joined together with the help of positioning devices. The postop rehabilitation included postop chemotherapy and mesodiencephalic modulation (MDM). The second part of the program comprised preop examination, modeling, using stereolytic 3-dimensional models of the mandible, corrective surgeries, including implantation into the auto-implantda fragment of patient’s fibula, and building of a removable titanium alloy–based denture. MDM sessions were administered after each invasive intervention. Conclusions: Higher psychological and physical well-being was observed in the experimental group as compared with the control group (P, 0.01) in 2 weeks after the first surgery and 2 months after scheduled corrective surgeries, which finished in denture installation.

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. Experimental validation of the method for regulation of stem cell proliferation and differentiation is carried out. The method consists in exposure to ultrahigh frequency electromagnetic radiation, modulated by infralow frequencies with variable parameters. A specially designed programmer, setting up the parameters of exposure, is connected to the source of radiation. The zones of anatomical location of the red bone marrow of rats were exposed for 15 min to the amplitude-modulated electromagnetic radiation of ultrahigh frequency range. The parameters of exposure were determined in previous studies. The red bone marrow was collected from the sternum and head of the femur. The cellular composition of the red bone marrow was evaluated 1, 2, 3, and 6 days after the exposure. The optimal therapeutic mode of irradiation was then chosen, leading to stem cell activation with subsequent proliferation and differentiation into mature red bone marrow cells.

© 2018, Media Sfera. All rights reserved. Surgical treatment of intraocular lens (IOL) with late dislocation remains one of the current problems of ophthalmology. Purpose - to evaluate specific morphofunctional changes in the eye after dislocated IOL exchange with retropupillary-fixated iris-claw IOL. Material and methods. Surgical outcomes of 150 patients (150 eyes) with in-the-bag IOL dislocation (122 eyes) or sulcus-fixated IOL dislocation (28 eyes) were analyzed. The follow-up period was 1-3 years. Results. Increase in visual acuity and stable retropupillary fixation of the IOL was observed in all cases after reimplantation. Mean endothelial cell loss after 3 months was 6.9±1.3% in the group with preoperative density of >1200 cells/mm 2 and 12.3±2.7% in the group with preoperative density of <1200 cells/mm 2 . There was no significant increase in intraocular pressure after IOL reimplantation. The incidence of clinical cystoid macular edema with decreased visual acuity was 4.7%, which is significantly more frequent than in patients after uncomplicated phacoemulsification with in-the-bag IOL implantation. Conclusion. Retropupillary implantation of iris-claw IOL provides stable fixation, good functional outcomes with low complication rates and is suitable for reimplantation in eyes without adequate capsular support.

It reports the results of primary basal blood flow in partially edentulous bone tissue with atrophy, as well as comparative evaluation of haemomicrocirculation level of the alveolar bone mucosa after bone augmentation via tunneling and conventional methods. The results of the initial state of microcirculation in the mucous membrane of the alveolar process in the partially edentulous area show a 45% decrease of blood flow (M), its intensity (s) by 60%. Microcirculatory shifts in blood flow levels indicators, its intensity, vasomotor activity are more evident when using the conventional method, where revascularization takes more than five months. When using the tunnel method, there is an improvement in haemodynamic mechanisms of tissue blood flow regulation. Microcirculation is restored 4 months after surgery.
