Cardiac magnetic resonance in cardiac angiosarcoma
Authors: Lindsey Jennifer , Stacey Richard B. 
Published: June 2017

BackgroundWhile echocardiography is effective for initial identification of anatomic location, magnetic resonance imaging (MRI) is a more advantageous modality for delineating tumor expanse, spread, and blood supply preoperatively. Emerging patterns may even help generate a specific diagnosis prior to biopsy and histopathology.Case PresentationOur case of a 67‐year‐old male referred for cardiac magnetic resonance to further evaluate a cardiac mass highlights the sophisticated level of data which can be collected. Our case highlights the perfusion related findings associated with cardiac angiosarcoma.ConclusionIn this case, we present the diagnosis of right atrial cardiac angiosarcoma by multiple imaging modalities including MRI and subsequent angiography, allowing for prompt surgical intervention and initiation of adjuvant therapy that resulted in a survival time of 19 months.
Preparation of nano‐structured pig bone hydroxyapatite for high‐efficiency adsorption of Pb2+ from aqueous solution
Authors: Zhou Yang , Chang Di , Chang Jiang 
Published: June 2017

AbstractThe nano‐structured hydroxyapatite was prepared from pig bone materials by mineralization. The obtained nano‐structured bone was much better compared to the bone without nanostructure for removing Pb2+. The process was investigated under different conditions including contact time, initial Pb2+ concentration, and pH. The pseudo‐second‐order kinetic model and Langmuir isotherm model were suitable for describing adsorption process. Moreover, the maximum adsorption capacities of nano‐structured bone and bone without nanostructure were 312.5 and 96.1 mg/g, respectively. Overall, the advantages of excellent adsorption capacity and simple mineralization together with low cost make nano‐structured bone an attractive material for removal of Pb2+ from aqueous solution.
Exile to Poverty: Policies and Poverty Among Refugees in Poland
Authors: Lukasiewicz Karolina 
Published: June 2017

AbstractPoverty is a well‐known short‐term outcome of migration in general and a long‐term outcome of forced migration in a global context. Surprisingly, this outcome appears among refugees in welfare states which provide various asylum and social policies facilitating integration. The article aims to explore the relationship between asylum and social policies and poverty among refugees. The research results are drawn from two studies conducted among refugees,NGOs, national and local administration representatives, and case workers in Poland between 2006 and 2014. The results show that asylum policy contributes to the material and symbolic hardship experienced by refugees, and social policy is ineffective in its prevention. If refugees are settled in regions with high levels of poverty, unemployment and ethnic‐based prejudices, then they experience and continue to live in poverty. In such a context, and due to its weaknesses in addressing discrimination, social policy cannot successfully integrate refugees.
Mental health nurses’ use of Twitter for professional purposes during conference participation using #acmhn2016
Authors: Salzmann‐Erikson Martin 
Published: June 2017

AbstractScholars across different disciplines use Twitter to promote research and to communicate with society. Most conferences nowadays have their unique hashtag in which participants can communicate in real time. Previous research has reported on conference participants’ use of Twitter, but no such studies are available in the field of mental health nursing. Thus, the explicit aim of the present study was to examine conference participants’ use of Twitter during the 42nd International Mental Health Nursing Conference. Freely‐accessible data were mined via a social media platform under the hashtag #acmhn2016. The total dataset consisted of 1973 tweets, and was analysed with descriptive statistics and a directed content analysis. The results demonstrated that 37% of the tweets were original posts, and 63% were engagements. In total, 184 individual accounts engaged in Twitter during the conference, and 16.4 tweets were posted hourly. Most tweets were categorized as conference/session‐related content, but Twitter was also used for socializing with other participants. The most frequently‐used words mirror a clear connection to a person‐centred approach, and deviate from the biomedical terminology. However, not all of the conference participants engaged on Twitter, and might thereby risk being excluded from this backchannel.

Published: June 2017

AbstractPiezoelectric energy harvester converts low‐frequency vibrational energy in the environment into electrical energy, enabling the purpose of self‐supplying power for low‐energy consumption devices. The key to miniaturizing energy harvester is the buildup of the submicron‐grained ceramic with a high transduction coefficient (d×g), which is still a big challenge from a technical point of view. In this work, the popular ternary system of Pb(Zn1/3Nb2/3)O3–Pb(Zr0.5Ti0.5)O3 (PZN–PZT) has been selected as objective compound, and the submicron‐grained ceramics were prepared by a combination of high‐energy ball milling and pressureless sintering technology. The results revealed that nanocrystalline PZN–PZT powders can be synthesized by one step mechanochemical route without the calcination stage. Using these nanopowders as precursors, dense ceramics with different grain size have been prepared through tailoring the sintering temperature. The study of size‐dependent energy harvesting characteristic evidenced an optimum transduction coefficient of 7980×10−15 m2/N was obtained for 950°C sintered specimen, which has uniform microstructure with mean grain size of 0.33 μm. In the mode of the cantilever‐type energy harvester constructed by this material, the output power at low frequency of 89 Hz was as high as 69 μW at an acceleration of 10 m/s2, showing the suitability for piezoelectric generators harvesting environmental vibrational energy.

Published: June 2017

AbstractA rare electromechanical resonance excited by a weak (<10 V/mm) alternating‐current electric field alone is observed in paraelectric KTa1‐xNbxO3 crystals near the Curie temperature. We show that the transformation from a disordered to an ordered polar‐nanoregion arrangement under the electric field enhances the electrostrictive effect near the phase transition, leading to strong electromechanical coupling. This result establishes the fundamental correlations between the polar nanoregions and the macroscopic physical properties in relaxor ferroelectrics.

Authors: Li Ning , Bai Yuelei , Wang Shuai , Zheng Yongting , Kong Fanyu , Qi Xinxin , Wang Rongguo , He Xiaodong , Duff Andrew Ian 
Published: June 2017

AbstractPolycrystalline Fe2AlB2 bulk including minor Al2O3 is synthesized by reactive hot pressing from Fe, Al, and B powders at 1200°C and 30 MPa for 30 minutes, with a relative density of 96%. The present approach enables a markedly reduced holding time compared with previous studies. The derived Fe2AlB2 shows an electrical resistivity of 2.27±0.01 μΩ·m, Vickers hardness of 10.2±0.2 GPa, flexural strength of 232±25 MPa, compressive strength of 2101±202 MPa, fracture toughness of 5.4±0.2 MPa·m1/2 and work of fracture of 117±12 J/m2. No dominant indentation cracks are observed, indicating that Fe2AlB2 may be quite damage tolerant. Interestingly, a noncatastrophic failure is present in the SENB test, with a high work of fracture. The energy‐absorbing mechanisms in inhibiting crack formation are delamination and pullout of Fe2AlB2 grains.

AbstractAims/IntroductionThe present study evaluated the ability of lipid accumulation product (LAP), visceral adiposity index (VAI), and the product of triglycerides and glucose (TyG), three novel markers, in identifying metabolic syndrome (MetS) with different criteria in middle‐aged and elderly Chinese.Materials and MethodsDuring June 2012 to January 2013, 992 consecutive patients (age ≥40 years) were enrolled at Daping Hospital. The criteria of MetS were based on the International Diabetes Federation and the modified National Cholesterol Education Program's Adult Treatment Panel III. VAI, LAP and TyG were computed based on a published mathematical model.ResultsThe prevalence of MetS was 42.8%. The receiver operating characteristic curve found LAP, VAI and TyG were positively related to MetS in both criteria. The optimal cut‐offs of VAI, LAP and TyG for the modified National Cholesterol Education Program's Adult Treatment Panel III and International Diabetes Federation criteria were 2.015, 31.465 and 8.706, and 2.035, 37.99 and 8.697, respectively. After adjustment of potential confounding factors, VAI, LAP and TyG were significantly correlated with MetS in all criteria according to optimal cut‐offs. For MetS, reliable predictive value was observed in different subgroups (age and sex). LAP showed the greatest area under the curve in MetS with the International Diabetes Federation definition (area under the curve 0.887, 95% confidence interval 0.852–0.922).ConclusionsAP, VAI and TyG were reliable surrogate markers for identifying MetS in middle‐aged and elderly Chinese. LAP could be a better parameter than VAI and TyG for predicting MetS in the present study.

Published: June 2017

ObjectivesTo explore the association between a newly developed cumulative laboratory‐based frailty index (FI) and intrinsic (personal) and extrinsic (social, environmental) characteristics.DesignCross‐sectional longitudinal study.SettingThe third and fourth waves of the community‐representative, five‐county, 10‐year Duke Established Populations for Epidemiologic Studies of the Elderly study, carried out in a health service‐rich area.ParticipantsCognitively intact survivors of the third wave (N = 1,740), who provided blood samples for standard laboratory work.MeasurementsBiomarkers (n = 28) were measured to develop a cumulative deficit laboratory test–based FI (Duke FI) derived from standard laboratory tests: SMAC‐24 chemistry panel, high‐density lipoprotein cholesterol panel, and complete blood count. Information was gathered on scales assessing intrinsic characteristics (personal locus of control, life satisfaction, self‐esteem, depressive symptomatology) and extrinsic characteristics (support received from and provided to family and friends, stressful life events, neighborhood disadvantage).ResultsThe newly developed Duke FI had content, construct, concurrent, and predictive validity. In addition to sex, race, and income, the Duke FI was associated at the intrinsic level with locus of control, self‐esteem, life satisfaction, and depressive symptomatology (each P < .01) and at the extrinsic level with provision (P < .01) and with receipt of instrumental help (P < .10), social stressors (P < .03), and neighborhood disadvantage (P < .01) in unadjusted analysis; race fully explained neighborhood disadvantage.ConclusionIntrinsic (personality) characteristics and personally close extrinsic characteristics (contacts with family and friends, personal stressors) are associated with laboratory test–based frailty, as is neighborhood disadvantage, although in this accessible, health service–rich environment, race fully explained association with neighborhood disadvantage, suggesting that interventions to reduce frailty in residents in such an environment should pay particular attention to characteristics that immediately affect the individual.
Agricultural Productivity Growth and Household Food Security Improvement in Nepal
Authors: Morioka Masako , Kondo Takumi 
Published: June 2017

AbstractNepal is one of the poorest countries in the world. Using the panel data of the Nepal Living Standard Measurement Survey (NLSS), the poverty rate in 1995–96 was estimated to be about 40%, while in 2003–04 it was estimated at roughly 30%. Political instability has prevented the development of industry and threatened the food security of poor people, but scholarship on the factors contributing to food security is incomplete; while the determinants of food security have been mentioned in past research, prior studies have analyzed cross‐sectional data and thus could not have omitted heterogeneity bias. This paper analyzes the change in agricultural productivity in real terms and the impact on household food security by using the panel data of NLSS in 1995–96 and 2003–04. This analysis reveals that growth is observed in real agricultural productivity in spite of land segmentation; the growth in agricultural productivity in real terms has a positive impact on household food security; and the lower a farmer's income becomes, the more positive its impact on food security. Therefore, advancements in agricultural productivity play a critical role in promoting food security at the individual and household levels.

AbstractThe nutritional quality of acid‐modified poultry manure biochar is unclear, so a better understanding of its properties and agronomic potential is needed. The biochar was modified with phosphoric acid (H3PO4) and nitric acid (HNO3) and a combination of the two, before and after pyrolysis. After characterization of biochar samples and determination of total and water‐soluble mineral element concentrations, biochars were applied to a calcareous soil at a rate of 0.5% (w/w) to find out their effects on the mineral nutrition and growth of maize. Treatment with H3PO4+HNO3enriches the biochar with phosphate, nitro groups and nitrate. The experimental results suggested that biochar modified withHNO3and/orHNO3+H3PO4after pyrolysis increased the water‐soluble phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn) concentrations and increased plant‐available nutrients and plant growth by positively affecting the absorption of plant nutrients. The highest plant dry weight was obtained from biochar post‐treated withHNO3+H3PO4,and this was followed byHNO3‐ and H3PO4‐modified biochars. Premodification withHNO3+H3PO4 also significantly increased plant dry weights. The results of this study revealed that poultry manure biochar modified withHNO3and H3PO4can be used effectively in calcareous soil for the improvement of plant mineral nutrition.

ObjectiveTo assess ampicillin levels according to the duration of intrapartum antibiotic prophylaxis (IAP).DesignProspective cohort single-centre study.SettingTertiary care centre (Modena, Italy).Patients120 neonates≥35 weeks’ gestation exposed to IAP.InterventionsNeonates were divided into four groups, according to the duration of IAP prior to delivery: group 1 (n=30; <1 hour), group 2 (n=30; ≥1 and <2 hours), group 3 (n=30; ≥2 and <4 hours) and group 4 (n=30; ≥2 doses, ≥4 hours).Main outcome measuresBlood samples were collected at delivery (from the umbilical cord) and at age 4 hours (from a peripheral vessel).ResultsMedian duration of IAP was 121 min (range 7–2045 min). Median ampicillin levels in umbilical cord blood were 10.4 µg/mL (IQR 6.4–14.9) and in peripheral blood were 4.7 µg/mL (IQR 2.8–6.4µg/mL). Umbilical cord blood levels reached a peak approximately 30 min after IAP and then declined significantly (p<0.001). Peripheral blood levels did not differ among study groups. Neonates exposed to a full loading dose (n=115) had peripheral blood levels 2.5–70 times higher than the minimal inhibitory concentration for group B streptococcus. There was no relationship between neonatal ampicillin concentrations and the duration of IAP prior to delivery (β=−0.0003, 95% CI −0.02 to 0.001, p=0.680).ConclusionsAmpicillin levels reach a peak in the umbilical cord blood within 30 min of intrapartum administration. After a full loading dose, bactericidal levels persist for at least 4 hours after birth and seem independent of the duration of IAP prior to delivery.

ObjectivesTo study fully automated digital joint space width (JSW) and bone mineral density (BMD) in relation to a conventional radiographic scoring method in early rheumatoid arthritis (eRA).MethodsRadiographs scored by the modified Sharp van der Heijde score (SHS) in patients with eRA were acquired from the SWEdish FarmacOTherapy study. Fully automated JSW measurements of bilateral metacarpals 2, 3 and 4 were compared with the joint space narrowing (JSN) score in SHS. Multilevel mixed model statistics were applied to calculate the significance of the association between ΔJSW and ΔBMD over 1 year, and the JSW differences between damaged and undamaged joints as evaluated by the JSN.ResultsBased on 576 joints of 96 patients with eRA, a significant reduction from baseline to 1 year was observed in the JSW from 1.69 (±0.19) mm to 1.66 (±0.19) mm (p<0.01), and BMD from 0.583 (±0.068) g/cm2to 0.566 (±0.074) g/cm2(p<0.01). A significant positive association was observed between ΔJSW and ΔBMD over 1 year (p<0.0001). On an individual joint level, JSWs of undamaged (JSN=0) joints were wider than damaged (JSN>0) joints: 1.68 mm (95% CI 1.70 to 1.67) vs 1.54 mm (95% CI 1.63 to 1.46). Similarly the unadjusted multilevel model showed significant differences in JSW between undamaged (1.68 mm (95% CI 1.72 to 1.64)) and damaged joints (1.63 mm (95% CI 1.68 to 1.58)) (p=0.0048). This difference remained significant in the adjusted model: 1.66 mm (95% CI 1.70 to 1.61) vs 1.62 mm (95% CI 1.68 to 1.56) (p=0.042).ConclusionsTo measure the JSW with this fully automated digital tool may be useful as a quick and observer-independent application for evaluating cartilage damage in eRA.Trial registration numberNCT00764725.

Published: June 2017

ObjectiveThe strong genetic association between HLA-B27 and ankylosing spondylitis has been known for over 40 years. HLA-B27 positivity is possibly associated with severity of ankylosis. We studied the in vitro and in vivo impact of HLA-B27 in models of chondrogenesis and osteogenesis.MethodsDifferent in vitro differentiation systems were used to mimic endochondral and direct bone formation. ATDC5 cells and primary human periosteum-derived cells (hPDCs) were transduced with lentiviral vectors expressing HLA-B27 or HLA-B7. These cells and limb bud cells (from HLA-B27 transgenic and wild-type (WT) mice) were cultured in micromasses. To study direct osteogenesis in hPDCs, cells were cultured as monolayers and stimulated with osteogenic media. Chondrogenesis (COL2,ACAN,COL10) and osteogenesis (OSC,ALP,RUNX2) marker expression was studied by quantitative RT-PCR. Colorimetric tests were performed to measure proteoglycans, mineralization and collagens. Collagen antibody-induced arthritis (CAIA) was induced in HLA-B27 transgenic and WT mice. Clinical scoring and µCTs were performed. Statistical analyses were performed by two-way ANOVA.ResultsThere was no difference in chondrogenesis markers or in colorimetric tests between HLA-B27+and HLA-B7+micromasses. Expression of osteogenesis markers and Alizarin red staining was comparable in the HLA-B27+and the HLA-B7+hPDCs in monolayers. HLA-B27 transgenic mice showed more severe arthritis compared with WT mice in the CAIA model. µCT analysis showed no increased bone formation in HLA-B27 transgenic mice.ConclusionHLA-B27 seems to enhance joint inflammation in the CAIA model. We could not document a direct effect of HLA-B27 on chondrogenesis or osteogenesis.

Published: June 2017

Radio-Frequency Identification (RFID) technology has the potential to provide inexpensive, wireless, battery-free connectivity and interactivity for objects that are traditionally not instrumented. However, these systems have not seen widespread deployment outside warehouses and supply chains, owing to the complexity of installing bulky RFID readers, antennas, and their supporting power and network infrastructure.
In this work, we leverage advances in semiconductor optics, RF antenna design and system integration to create a hybrid RFID reader and smart LED lamp, in the form factor of a standard light bulb. This makes deploying RFID readers literally as easy as screwing in a light bulb. We explore the home-scale RFID interactions enabled by these smart bulbs, including infrastructure monitoring, localization and guided navigation, and standalone lighting effects.
