The prognosis of the antineutrophil cytoplasmic antibody associated vasculitides (AAV), microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA) and eosinophilic GPA (EGPA), has been fundamentally improved over the last five decades by the use of glucocorticoids and immunosuppressants, turning them from consistently fatal diseases into chronic conditions. The long-term course is now largely determined by the frequency of disease flares and by accruing damage caused by disease activity and treatment-related comorbidities...

: Denitrifying Epsilonproteobacteria may dominate nitrogen loss processes in marine habitats with intense redox gradients but assessment of their importance is limited by currently available primers for nitrite reductase genes. Nine new primers targeting the nirS gene of denitrifying Epsilonproteobacteria were designed and tested for use in sequencing and quantitative PCR on two microbial mat samples (Vent 2 and Vent 4) from the Calypso hydrothermal vent field, Bay of Plenty, New Zealand...

The renin-angiotensin system (RAS) is one of important systems among homeostatic mechanisms that controls the function of cardiovascular, renal and adrenal systems. As RAS has a very complex nature, it has been also found as related to the control of cell migration and apoptosis. Angiotensin-converting enzyme inhibitors (ACEI) are drugs most commonly used in the modulation of RAS activity. ACEI have been extensively described as effective in the treatment of hypertension among adults, but also as drugs delaying progression in diabetic nephropathy and reducing mortality in left ventricular dysfunction and congestive heart failure...

An ideal antibiotic is an antibacterial agent that kills or inhibits the growth of all harmful bacteria in a host, regardless of site of infection without affecting beneficial gut microbes (gut flora) or causing undue toxicity to the host. Sadly, no such antibiotics exist. What exists are many effective Gram-positive antibacterial agents as well as broad-spectrum agents that provide treatment of certain Gram-negative bacteria but not holistic treatment of all bacteria. However effectiveness of all antibacterial agents is being rapidly eroded due to resistance...

A simplistic view of the adaptive process pictures a hillside along which a population can climb: when ecological 'demands' change, evolution 'supplies' the variation needed for the population to climb to a new peak. Evolutionary ecologists point out that this simplistic view can be incomplete because the fitness landscape changes dynamically as the population evolves. Geneticists meanwhile have identified complexities relating to the nature of genetic variation and its architecture, and the importance of epigenetic variation is under debate...

BACKGROUND: Although a wide range of preventive and clinical interventions has targeted cardiovascular risk management (CVRM), outcomes remain suboptimal. Therefore, the question is what additional determinants of CVRM and outcomes can be identified and addressed to optimize CVRM. In this study, we aimed to identify new perspectives for improving healthcare delivery and explored associations between information exchange networks of health care providers and evidence-based CVRM. METHODS: This observational study was performed parallel to a randomized clinical trial which aimed to improve professional performance of practice nurses in the Netherlands...

Alien species are a major component of human-induced environmental change. Variation in the numbers of alien species found in different areas is likely to depend on a combination of anthropogenic and environmental factors, with anthropogenic factors affecting the number of species introduced to new locations, and when, and environmental factors influencing how many species are able to persist there. However, global spatial and temporal variation in the drivers of alien introduction and species richness remain poorly understood...

PURPOSE: The direct impact of protracted conflict on population health and development is well understood. However, the extent of a war's impact on long-term health, and the opportunity costs, are less well understood. This research sought to overcome this gap by asking whether or not health outcomes in Sri Lanka would have been better in the absence of a 26-year war than they were in the presence of war. METHODS: A counterfactual model of national and district-level health outcomes was created for Sri Lanka for the period 1982 to 2002...

Since 2006, there has been a marked increase in the number of reports of severe and often fatal fungal skin infections in wild snakes in the eastern USA. The emerging condition, referred to as snake fungal disease (SFD), was initially documented in rattlesnakes, where the infections were believed to pose a risk to the viability of affected populations. The disease is caused by Ophidiomyces ophiodiicola, a fungus recently split from a complex of fungi long referred to as the Chrysosporium anamorph of Nannizziopsis vriesii (CANV)...

Issue: Republicans in Congress are expected to repeal portions of the Affordable Care Act (ACA) using a fast-track process known as budget reconciliation. Goals: This issue brief examines how repeal legislation could affect Medicaid, the nation’s health care safety net, which insured 70 million people in 2016. Findings and Conclusions: Partial-repeal legislation that passed Congress but was vetoed by President Obama in 2016 offers some insight but new legislation could go further. It could repeal the ACA’s Medicaid eligibility expansions for adults and children but also roll back other provisions, such as simplified enrollment and improvements in long-term services and supports for beneficiaries with disabilities...

Although they were first synthesized in chemistry laboratories nearly fifty years ago, the physical properties of the metals PdCoO2, PtCoO2 and PdCrO2 have only more recently been studied in detail. The delafossite structure contains triangular co-ordinated atomic layers, and electrical transport in the delafossite metals is strongly 2D. Their most notable feature is their in-plane conductivity, which is amazingly high for oxide metals. At room temperature, the conductivity of non-magnetic PdCoO2 and PtCoO2 is higher per carrier than those of any alkali metal and even the most conductive elements, copper and silver...

There is a strong interrelationship within the cell nucleus between form and function of the genome. This connection is exhibited across multiple hierarchies, ranging from grand-scale positioning of chromosomes and their intersection with specific nuclear functional activities, the segregation of chromosome structure into distinct domains and long-range regulatory contacts that drive spatial and temporal expression patterns of genes. Fifteen years ago, the development of the chromosome conformation capture method placed the nature of specific, long-range regulatory interactions under scrutiny...

: Diarrhea-associated hemolytic uremic syndrome (D+HUS) is a common thrombotic microangiopathy during childhood and early identification of parameters predicting poor outcome could enable timely intervention. This study aims to establish the accuracy of BUN-to-serum creatinine ratio at admission, in addition to other parameters in predicting the clinical course and outcome. Records were searched for children between 1 January 2008 and 1 January 2015 admitted with D+HUS. A complicated course was defined as developing one or more of the following: neurological dysfunction, pancreatitis, cardiac or pulmonary involvement, hemodynamic instability, and hematologic complications while poor outcome was defined by death or development of chronic kidney disease...

: In paediatric palliative care (PPC), parents are confronted with increasing caregiving demands. More children are cared for at home, and the need for PPC of children is lengthened due to technical and medical improvements. Therefore, a clear understanding of the content of parental caregiving in PPC becomes increasingly important. The objective is to gain insight into parental caregiving based on the lived experience of parents with a child with a life-limiting disease. An interpretative qualitative study using thematic analysis was performed...

Identifying and implementing thoughtful, evidence based (or at least evidence informed) public health approaches to impacting obesity is a complex issue fraught with multiple challenges. These challenges begin with determining whether obesity policy approaches should be implemented. This is considered within the broader context of how common public health policy approaches may be relevant and applied to obesity. Additional challenges discussed include inconsistencies in clearly identifying obesity policy targets (e...

The structures of apomyoglobin folding intermediates have been widely analyzed using physical chemistry methods including fluorescence, circular dichroism, small angle X-ray scattering, NMR, mass spectrometry, and rapid mixing. So far, at least two intermediates (on sub-millisecond- and millisecond-scales) have been demonstrated for apomyoglobin folding. The combination of pH-pulse labeling and NMR is a useful tool for analyzing the kinetic intermediates at the atomic level. Its use has revealed that the latter-phase kinetic intermediate of apomyoglobin (6 ms) was composed of helices A, B, G and H, whereas the equilibrium intermediate, called the pH 4 molten-globule intermediate, was composed mainly of helices A, G and H...

The American Thoracic Society has previously published statements on what constitutes an adverse effect on health of air pollution in 1985 and 2000. We set out to update and broaden these past statements that focused primarily on effects on the respiratory system. Since then, many studies have documented effects of air pollution on other organ systems, such as on the cardiovascular and central nervous systems. In addition, many new biomarkers of effects have been developed and applied in air pollution studies...

BACKGROUND: With increasing evidence for the effectiveness of e-mental health interventions for enhancing mental health and well-being, a growing challenge is how to translate promising research findings into service delivery contexts. A 2012 e-mental health initiative by the Australian Federal Government (eMHPrac) has sought to address the issue through several strategies, one of which has been to train different health professional workforces in e-mental health (e-MH). OBJECTIVE: The aim of the study was to report on the barriers and enablers of e-MH uptake in a cohort of predominantly Aboriginal and Torres Strait Islander health professionals (21 Indigenous, 5 non-Indigenous) who occupied mainly support or case management roles within their organizations...
