Unlike in most of the world, HIV incidence in the former Soviet Union continues to rise. While international labor migration has been identified as a potentially important contributor to this trend, most attention has been focused on risks of male migrants themselves. This study uses recent household survey data to examine HIV-related perceptions and actions of migrants' left-behind wives in Armenia. Multivariate logistic regression analyses show that migrants' wives are significantly more likely to suspect their husbands of extramarital sex than are non-migrants' wives...

Tissue engineering and regenerative medicine have significant potential to treat bone pathologies by exploiting the capacity for bone progenitors to grow and produce tissue constituents under specific biochemical and physical conditions. However, conventional tissue engineering approaches, which combine stem cells with biomaterial scaffolds, are limited as the constructs often degrade, due to a lack of vascularisation, and lack the mechanical integrity to fulfil loading bearing functions, and as such are not yet widely used for clinical treatment of large bone defects...

The objective of the present study was to analyze the clinical and radiological results of periacetabular osteotomies (PAO) using Kirschner wire fixation and an allogeneic cancellous bone graft. This retrospective cohort study included 73 patients (85 PAOs). The allografts were processed from distal femur of cadaveric donors, defatted, sterilized with a peracetic-acid ethanol solution and freeze-dried. The clinical outcome, as measured by the Harris Hip Scores (HHS), the complication rate and the acetabular correction, as measured by radiological parameters, were compared...

BACKGROUND: Perampanel, a new specific non-competitive AMPA receptor antagonist, has been recently approved in the United States and the European Union for the adjunctive treatment of focal seizures and primary generalized tonic-clonic seizures associated with idiopathic generalized epilepsy. A positive relationship between plasma perampanel concentration and improvement in seizure control has been identified in regulatory trials, suggesting that therapeutic drug monitoring (TDM) could be useful in optimizing clinical response in patients with epilepsy treated with perampanel...

We present the case of fishtail deformity of distal humerus in a 13-year-old boy presenting with a refracture 8 years after the original surgically treated lateral condyle fracture. This unusual incomplete vertical fracture of distal humerus starting at the apex of fishtail was treated non-surgically and went on to union but refractured yet again 12 months later. This also went on to full healing with conservative treatment, however the fishtail deformity persists. We discuss the possibility that fishtail deformity reflects an inherent weakness in the distal humerus...

In these days of political vagueness, to use a kinder term, although many would describe the situation as turmoil, in Europe, there are success stories to be lauded. Notwithstanding the direction individual countries choose in relation to closer or not so close co-operation in Europe and the direction the political agenda will travel over the next few years, I believe science and in particular medicine has benefited enormously form close co-operation across the European Union and with colleagues outside this political and trading block of nations...

BACKGROUND: Close contact casting (CCC) may offer an alternative to open reduction and internal fixation (ORIF) surgery for unstable ankle fractures in older adults. OBJECTIVES: We aimed to (1) determine if CCC for unstable ankle fractures in adults aged over 60 years resulted in equivalent clinical outcome compared with ORIF, (2) estimate cost-effectiveness to the NHS and society and (3) explore participant experiences. DESIGN: A pragmatic, multicentre, equivalence randomised controlled trial incorporating health economic evaluation and qualitative study...

BACKGROUND: Informal settlements are common throughout the developing world. In Peru, land occupations, commonly "invasions" in Spanish, are a means by which the extremely poor attempt to obtain access to land. Here, we examine difference in child health between two communities in the Peruvian Amazon, one well-established and one newly formed by 'invasion', as captured incidentally by a prospective epidemiological cohort study. METHODS: Between 2002 and 2006 a study designed to describe the epidemiology of pediatric enteric infections and child growth in a community-based setting enrolled 442 children in Santa Clara de Nanay, a community adjacent to the city of Iquitos, in Loreto, Peru...

The incidence of any fracture in the US is estimated to be 2 704 fractures per 100,000 person-years. Approximately 10 percent of these fractures develop complications of healing. The processes that occur during fracture healing mimic the processes that take place in the growth plate during development. The study of fracture healing represents a window to enhance our understanding of the processes of growth and development of bones and its reparative biology. This review is aimed for clinicians evaluating non-unions as an overview of different factors that inhibit fracture healing...

Non-point source pollution is a cause of major concern within the European Union. This is reflected in increasing public and political focus on a more sustainable use of pesticides, as well as a reduction in diffuse pollution. Climate change will likely to lead to an even more intensive use of pesticides in the future, affecting agriculture in many ways. At the same time, the Water Framework Directive (WFD) and associated EU policies called for a "good" ecological and chemical status to be achieved for water bodies by the end of 2015, currently delayed to 2021-2027 due to a lack of efficiency in policies and timescale of resilience for hydrosystems, especially groundwater systems...

BACKGROUND: Scaphoid fractures represent the most common carpal fractures and are often problematic and frequently lead to nonunion with osteoarthritis and collapse of the wrist. The reasons for the nonunion are manifold. Therefore, the main goal of diagnosis and therapy of acute fractures is to achieve bony union and to restore the anatomic shape of the scaphoid. In the long run, only this can preserve the normal function of the wrist. METHODOLOGY: The given recommendations are based on the new S3-level guideline of the AWMF (Association of the Scientific Medical Societies)...

Potato is one of the most important crops, after maize, rice and wheat. Its global production is about 300 million tons per year and is constantly increasing. It grows in temperate climate and is used as a source of starch, food, and in breeding industry.Potato cultivation requires application of numerous agro-technical products, including pesticides, since it can be affected by insects, weeds, fungi, and viruses. In the European Union the most frequently used pesticides in potato cultivations check are: thiamethoxam, lambda-cyhalothrin and deltamethrin (insecticides), rimsulfuron (herbicide) and metalaxyl (fungicide)...

Interest is increasing in the development of non-animal methods for toxicological evaluations. These methods are however, particularly challenging for complex toxicological endpoints such as repeated dose toxicity. European Legislation, e.g., the European Union's Cosmetic Directive and REACH, demands the use of alternative methods. Frameworks, such as the Read-across Assessment Framework or the Adverse Outcome Pathway Knowledge Base, support the development of these methods. The aim of the project presented in this publication was to develop substance categories for a read-across with complex endpoints of toxicity based on existing databases...
