As soil-extractable elements potentially pose ecological and health risks, identifying their contamination characteristics and sources is crucial. Therefore, to understand topsoil trace elements in the urban ring zone from the Second Ring Road to the Third Ring of Xi'an city in China, we determined the concentrations of Zn, Co, V, As, Cu, Mn, Ba, Ni and Pb, and analyzed the sources of the contamination. The results showed that the individual pollution indices of Pb, Co, Cu, Zn, Ba, Ni, Mn, As, and V were 1...

Solstice® Performance Fluid (PF), trans-1-chloro-3,3,3-trifluoropropene, is presented as an alternative to HFE7100, methoxy-nonafluorobutane, as a carrier solvent in a number of chemical formulations used for the visualisation of latent fingermarks. The supply of HFE7100 may be at risk due to a recent European Union regulation to control global warming. Laboratory trials using split depletions and a pseudo-operational trial of 1000 porous samples have shown that Solstice® PF is a viable alternative to HFE7100 for the chemical formulations of ninhydrin and 1,2-indanedione...

BACKGROUND: Oral HIV pre-exposure prophylaxis (PrEP) has been recommended as a means of HIV prevention among people who inject drugs (PWID) but, at current prices, is unlikely to be cost-effective for all PWID. OBJECTIVE: To determine the cost-effectiveness of alternative strategies for enrolling PWID in PrEP. DESIGN: Dynamic network model that captures HIV transmission and progression among PWID in a representative US urban center. OUTCOME MEASURES: HIV infections averted, discounted costs and quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs)...

BACKGROUND: Several studies have reported the epidemiology of immune thrombocytopenia (ITP) among children in the United States and other countries. However, recent trends in ITP among hospitalized children and hospital course remain unknown at a national level in the United States. METHOD: Hospital discharge records of patients with ITP aged 19 years and younger were obtained for the years 2003, 2006, 2009, and 2012 using the Kids' Inpatient Database. Data were weighted to estimate the annual hospitalization rates in the United States with trend analyses...

On the basis of significant evidence for safety, the international pediatric fever and neutropenia committee recommends the identification and management of patients with "low-risk fever and neutropenia" (LRFN), outpatient with oral antibiotics, instead of traditional inpatient management. The aim of our study was to compare the cost-per-patient with these 2 strategies, and to evaluate parent and provider satisfaction with the outpatient management of LRFN. Between March 2016 and February 2017, 17 LRFN patients (median absolute neutrophil count, 90/μL) were managed at a single institution, per new guidelines...

PURPOSE OF REVIEW: To review the current literature regarding the role of multiparametric MRI and fusion-guided biopsies in urologic practice. RECENT FINDINGS: Fusion biopsies consistently show an increase in the detection of clinically significant cancers and decrease in low-risk disease that may be more suitable for active surveillance. Although, when to incorporate multiparametric MRI into workup is not clearly agreed upon, studies have shown a clear benefit in both biopsy naïve and those with prior negative biopsies in determining the appropriate treatment strategy...

Nanostructured poly(m-aminophenol) (PmAP) coated freestanding carbon nanofiber (CNF) mats were fabricated through simple in-situ rapid-mixing polymerization of m-aminophenol in presence of CNF mat for flexible solid-state supercapacitors. The surface compositions, morphology and pore structure of the hybrid mats were characterized by using different techniques, e.g., FTIR, Raman, XRD, FE-SEM, TEM and N2 absorption. The results show that the PmAP nanoparticles homogeneously deposited on CNF surfaces and formed a thin flexible hybrid mat, which were directly used to made electrodes for electrochemical analysis without using any binders and conductive additives...

Oral diseases, particularly caries and gingivitis, continue to be widespread. Incorporating a stabilized stannous fluoride dentifrice into patients' daily oral hygiene routine is a convenient, cost effective approach to improve and protect their oral health and the appearance of their smile. Unlike other common fluorides that only provide anti-caries benefits (e.g., sodium fluoride and sodium monofluorophosphate), stabilized stannous fluoride formulations have demonstrated broader and significantly greater protection, also reducing plaque, gingivitis, erosion, sensitivity, and halitosis...

The nuclear disasters of Chernobyl and Fukushima presented an urgent need for finding solutions to treatment of radioactive wastes. Among the by-products of nuclear fission is the radioactive 137Cs, which evokes an environmental hazard due to its long half-life (>30 years) and high solubility in water. In this work, a water-soluble organic ligand, readily obtained from alloxan and 1,3,5-benzenetriol, has been found to selectively bind and precipitate Cs+ ions from aqueous solutions. The special rigid structure of the ligand, which consists of a "tripodal" carbonyl base above and below an aromatic plane, contributes to the size-driven selectivity towards the large Cs+ ions and the formation of a giant, insoluble supramolecular complex...

Biomarkers associated with prognosis in multiple myeloma (MM) can be used to stratify patients into risk categories. An attractive alternative to uniform treatment (UT), risk-stratified treatment (RST) is proposed where high-risk patients receive bortezomib-based regimens while standard-risk patients receive alternative less costly regimens. An early Markov-type decision analytic model evaluated the potential therapeutic and economic value of different RST strategies compared with UT in MM patients in key European countries...

In the case of primary male hypogonadism (HG), only testosterone (T) replacement therapy (TRT) is possible whereas when the problem is secondary to a pituitary or hypothalamus alteration both T production and fertility can be, theoretically, restored. We here systematically reviewed and discussed the advantages and limits of medications formally approved for the treatment of HG. Areas covered: Data derived from available meta-analyses of placebo controlled randomized trials (RCTs) were considered and analyzed...

Crystal Jing Jing Yeo, Zachary Simmons
The recent approval of edaravone by the United States Food and Drug Administration has generated a mix of hope tempered by reality. The costs of the drug, both monetarily and with regard to intensity of treatment, are high. The benefits, while modest, will be viewed through a very different lens by individuals depending on their goals of care. By virtue of our training and experience, physicians are ideally suited to understand and explain new treatments to our patients. As healthcare providers with a fiduciary responsibility to our patients, we must make sure they are fully informed about both the costs and benefits of non-curative therapies such as edaravone, and be prepared to discuss these in the context of their goals of care and potential impact on quality of life...

Schizophrenia and other types of psychosis incur suffering, high health care costs and loss of human potential, due to the combination of early onset and poor response to treatment. Our ability to prevent or cure psychosis depends on knowledge of causal mechanisms. Molecular genetic studies show that thousands of common and rare variants contribute to the genetic risk for psychosis. Epidemiological studies have identified many environmental factors associated with increased risk of psychosis. However, no single genetic or environmental factor is sufficient to cause psychosis on its own...
