The functions of some bone proteins, as osteopontin (OPN) and osteocalcin (OC), have been discovered by the latest studies. This fact suggests the possibility of their immunodetection to characterize peri-implant osteogenesis and implant impact on it. Cylindrical pins of Mg alloys (MgCa0.8, LAE442, ZEK100, LANd442) and titanium alloy (TiAl6V4) were implanted into the tibial medullae of 46 rabbits. Each group was divided regarding to implant duration (3 and 6 months). Bone samples adjacent to the implants were decalcified and treated with routine histological and immunohistochemical protocols using OC and OPN-antibodies. OC was detected in matrix of compact bone, but very rarely in osteoid and bone cells. OPN was detected intracellularly and in osteoid. After 3 months, the highest level of both markers was found in titanium group, followed by LAE442-group. In contrast to LAE442 and TiAl6V4, the other Mg alloys showed increasing levels of OC after 6 months. Lower levels of OP and OC compared to the control group are related to the continuous implant degradation and instability of bone-implant interface in early post-surgical period. Reduced marker's expression in LAE442 and TiAl6V4 groups after 6 months may indicate stabilization of bone-implant interface and completion of peri-implant neo-osteogenesis. Declining characters of OC and OPN expression over the implantation time, as well as their lowest levels in late post-surgical term, suggest a more appropriate biocompatibility of LAE442, which therefore seems to be the most preferable of the tested materials for the use in orthopaedic applications. © 2013 Wiley Periodicals, Inc.

Health systems in transition | Year: 2010
The HiT profiles are country-based reports that provide a detailed description of a health system and of policy initiatives in progress or under development. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. The Ukrainian health system has preserved the fundamental features of the Soviet Semashko system against a background of other changes, which are developed on market economic principles. The transition from centralized financing to its extreme decentralization is the main difference in the health system in comparison with the classic Soviet model. Health facilities are now functionally subordinate to the Ministry of Health, but managerially and financially answerable to the regional and local self-government, which has constrained the implementation of health policy and fragmented health financing. Health care expenditure in Ukraine is low by regional standards and has not increased significantly as a proportion of gross domestic product (GDP) since the mid 1990s; expenditure cannot match the constitutional guarantees of access to unlimited care. Although prepaid schemes such as sickness funds are growing in importance, out-of-pocket payments account for 37.4% of total health expenditure. The core challenges for Ukrainian health care therefore remain the ineffective protection of the population from the risk of catastrophic health care costs and the structural inefficiency of the health system, which is caused by the inefficient system of health care financing. Health system weaknesses are highlighted by increasing rates of avoidable mortality. Recent political impasse has complicated health system reforms and policy-makers face significant challenges in overcoming popular distrust and fatigue in the face of necessary but as yet unimplemented reforms.

Purpose: Parkinson's disease (PD) is characterized by striatal synaptic deafferentation followed by dopaminergic cell death in the substantia nigra pars compacta. Not only degenerative, but also regenerative, compensatory changes at distant sites of the primary lesion may occur in PD. The aim of the study was to analyze the temporal pattern of axonal and glial responses over a time course of six weeks post-lesioning. Methods: For this aim, 6-hydroxydopamine (6-OHDA) was injected unilaterally into the medial forebrain bundle and both lesioned and non-lesioned striata were analyzed. Results: We detected increased tyrosine hydroxylase (TH) immunoreactivity within the non-lesioned striatum six weeks after injection indicative either of increased TH expression or compensatory neuritic changes. An increased number of microglial cells was present in both lesioned and unlesioned striata. There was no obvious change in microglial phenotype or in pro-inflammatory cytokine gene expression within the striatum without any apparent switch into a pro-inflammatory phenotype. No changes were observed in the number of mature oligodendrocytes. Conclusions: This temporal pattern shows, that the non-lesioned striatum undergoes profound changes, involving increased TH expression accompanied by a glial response. A better understanding of this complex interplay of neuronal as well as glial components not only within the lesioned, but also non-lesioned striatum may help to restore local neural circuits in PD. © 2014 - IOS Press and the authors.

Background: The efficacy and safety of axitinib, a potent and selective second-generation inhibitor of vascular endothelial growth factor receptors 1, 2, and 3 in combination with pemetrexed and cisplatin was evaluated in patients with advanced non-squamous non-small-cell lung cancer (NSCLC). Methods: Overall, 170 patients were randomly assigned to receive axitinib at a starting dose of 5-mg twice daily continuously plus pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 on day 1 of up to six 21-day cycles (arm I); axitinib on days 2 through 19 of each cycle plus pemetrexed/cisplatin (arm II); or pemetrexed/cisplatin alone (arm III). The primary endpoint was progression-free survival (PFS).Results: Median PFS was 8.0, 7.9, and 7.1 months in arms I, II, and III, respectively (hazard ratio: arms I vs. III, 0.89 [P = 0.36] and arms II vs. III, 1.02 [P = 0.54]). Median overall survival was 17.0 months (arm I), 14.7 months (arm II), and 15.9 months (arm III). Objective response rates (ORRs) for axitinib-containing arms were 45.5% (arm I) and 39.7% (arm II) compared with 26.3% for pemetrexed/cisplatin alone (arm III). Gastrointestinal disorders and fatigue were frequently reported across all treatment arms. The most common all-causality grade ≥3 adverse events were hypertension in axitinib-containing arms (20% and 17%, arms I and II, respectively) and fatigue with pemetrexed/cisplatin alone (16%). Conclusion: Axitinib in combination with pemetrexed/cisplatin was generally well tolerated. Axitinib combinations resulted in non-significant differences in PFS and numerically higher ORR compared with chemotherapy alone in advanced NSCLC.Trial registration: ClinicalTrials.gov: NCT00768755 (October 7, 2008). © 2014 Belani et al.; licensee BioMed Central Ltd.

Background: Lipegfilgrastim is a novel glyco-pegylated granulocyte-colony stimulating factor in development for neutropenia prophylaxis in cancer patients receiving chemotherapy. This phase III, double-blind, randomized, active-controlled, noninferiority trial compared the efficacy and safety of lipegfilgrastim versus pegfilgrastim in chemotherapy-naïve breast cancer patients receiving doxorubicin/docetaxel chemotherapy.Methods: Patients with high-risk stage II, III, or IV breast cancer and an absolute neutrophil count ≥1.5 × 109 cells/L were randomized to a single 6-mg subcutaneous injection of lipegfilgrastim (n = 101) or pegfilgrastim (n = 101) on day 2 of each 21-day chemotherapy cycle (4 cycles maximum). The primary efficacy endpoint was the duration of severe neutropenia during cycle 1.Results: Cycle 1: The mean duration of severe neutropenia for the lipegfilgrastim and pegfilgrastim groups was 0.7 and 0.8 days, respectively (λ = -0.218 [95% confidence interval: -0.498%, 0.062%], p = 0.126), and no severe neutropenia was observed in 56% and 49% of patients in the lipegfilgrastim and pegfilgrastim groups, respectively. All cycles: In the efficacy population, febrile neutropenia occurred in three pegfilgrastim-treated patients (all in cycle 1) and zero lipegfilgrastim-treated patients. Drug-related adverse events in the safety population were reported in 28% and 26% of patients i006E the lipegfilgrastim and pegfilgrastim groups, respectively.Conclusion: This study demonstrates that lipegfilgrastim 6 mg is as effective as pegfilgrastim in reducing neutropenia in patients with breast cancer receiving myelosuppressive chemotherapy.Trial Registration: Eudra EEACTA200901599910. The study protocol, two global amendments (Nos. 1 and 2), informed consent documents, and other appropriate study-related documents were reviewed and approved by the Ministry of Health of Ukraine Central Ethics Committee and local independent ethics committees (IECs). © 2013 Bondarenko et al.; licensee BioMed Central Ltd.
