BACKGROUND: Titanium and polyetheretherketone (PEEK) implants have been used in spinal surgery with low rejection rates. Compared to titanium, PEEK has many advantages, including a density more similar to that of bone, radiolucency, and a lack of artifacts in computed tomography (CT) and magnetic resonance imaging (MRI). In this study, we evaluated the effectiveness of PEEK cages as an alternative to titanium for bone fusion after fractures of the thoracolumbar spine. We also propose a classification to the impaction index...

Xuesong Guo, Naim Kapucu
Disaster resettlement, as a mitigation and preparedness measure, entails significant economic, physical, and social impacts, which continue to challenge understanding of recovery from major events, especially regarding the extent of the context and environmental efforts to rebuild livelihoods. Based on a case study of Qinling Mountains, China, this research investigates the effects of disaster resettlement from a livelihoods perspective. Methodologically, it proposes a framework that combines the pressure-state-response framework and the sustainable livelihoods approach, and it employs a structural equation model to examine how specific factors affect disaster resettlement...

Two hundred million girls and women in the world are estimated to have undergone female genital mutilation (FGM), and another 15 million girls are at risk of experiencing it by 2020 in high prevalence countries (UNICEF, 2016. Female genital mutilation/cutting: a global concern. 2016). Despite decades of concerted efforts to eradicate or abandon the practice, and the increased need for clear guidance on the treatment and care of women who have undergone FGM, present efforts have not yet been able to effectively curb the number of women and girls subjected to this practice (UNICEF...

Glycopeptides are an important class of antibiotics used in the treatment of several infections, including those caused by methicillin resistant Staphylococcus aureus. Glycopeptides are biosynthesized by a Non Ribosomal Peptide Synthase (NRPS) and the resulting peptide precursors are decorated by several tailoring enzymes, such as halogenases and glycosyltransferases. These enzymes are important targets of protein engineering to produce new derivatives of known antibiotics. Herein we show the production of two putative halogenases, denominated StaI and StaK, involved in the biosynthesis of the glycopeptide A47,934 in Streptomyces toyocaensis NRRL 15,009...

BACKGROUND: Regular physical activity has important health benefits for children with type 1 diabetes mellitus (T1DM), yet children and their parents face barriers to participation such as lack of self-efficacy or concerns around hypoglycaemia. Multimedia interventions are useful for educating children about their health and demonstrate potential to improve children's health-related self-efficacy, but few paediatric clinics offer web-based resources as part of routine care. The Steps to Active Kids with Diabetes (STAK-D) programme is an online intervention grounded in psychological theory (social cognitive theory) and informed by extensive preliminary research...

The use of dietary supplements (DS) is common in the active duty population, often without physician knowledge or approval. DS have been associated with drug-induced liver injury, with rare cases resulting in liver failure or death. We report five cases of transient drug-induced liver injury temporally associated with the use of a total of six DS in active duty service members. All patients presented with elevated serum bilirubin and liver-associated enzymes: three patients had a cholestatic liver enzyme pattern, one had a hepatocellular pattern, and one had a mixed pattern...

OBJECTIVE: There is a link between the symptoms of hyperactivity/inattention and overweight in children. Less is known about the factors which might influence this relationship, such as physical and sedentary activity levels or exercise self-efficacy. The aim of this study is to examine the associations between the symptoms of hyperactivity/inattention and risk factors for adult obesity in a sample of children with barriers to exercise. DESIGN: Children aged 9-11 years were recruited from 24 primary schools that participated in the Steps to Active Kids (STAK) physical activity intervention study...

BACKGROUND: Low levels of physical activity in children have been linked to an increased risk of obesity, but many children lack confidence in relation to exercise (exercise self-efficacy). Factors which can impact on confidence include a chronic health condition such as asthma, poor motor skills and being overweight. Increasing levels of physical activity have obvious benefits for children with asthma and children who are overweight, but few activity interventions with children specifically target children with low exercise self-efficacy (ESE)...

Rahul K Dhanda, Philip R Reilly
Newborn screening raises many ethical and legal concerns, from the bioethics issues commonly faced with genetic testing and the practice of informed consent to the classical medical ethics questions that surround resource allocation. This mandatory, state-based healthcare intervention has not met with the resistance that one might have anticipated, yet it is still not integrated into society to its full potential. While there is room for newborn screening programs to improve on the technical, ethical, and legal fronts, this should not discourage policymakers, physicians, scientists, and other stak-holders from learning from the successful aspects of its implementation and applying these lessons to other, related technologies...
