Authors: Huang Min‐Guang , Xie Ze‐Min , Lai Xiao‐Zheng 
Published: May 2016

ABSTRACTIn this article, a compact multiband planar inverted‐F antenna (PIFA) is proposed to cover three frequency bands for RFID operation: 920–925 MHz, 2.4–2.48 GHz, 5.815–5.875 GHz. The multiband PIFA has the advantage of compact size of 55 × 40 × 0.8 mm3. The antenna proposed herein was composed of a modified planar inverted‐F with a loaded arm and a parasitic inverted‐L. The lowest band is achieved by the modified planar inverted‐F and the highest band is achieved by the parasitic inverted‐L. With the loaded arm, the band from 2.4 GHz to 2.48 GHz is achieved. The current distribution and radiation patterns are studied in this article. The antenna was fabricated on the FR4 substrate, providing the return loss less than −10 dB over all bands of interest. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1934–1937, 2016

Published: May 2016

ABSTRACTThis paper reports a novel multimode resonator (MMR) ultra‐wide band‐pass (UWB) filter design using a grounded open ring resonator. The utilization of 30 μm gaps between input ports and the central resonator achieve high coupling level. Five resonant modes are used to perform a 128% fractional bandwidth at 4.3 GHz. The fabricated prototype exhibits a band‐pass with insertion losses around 0.5 dB. A theoretical model based on transmission lines matrices is proposed and used to explore the limits of the design through different parametric analysis. Excellent agreement between theoretical predictions, electromagnetic simulations and measurement are found. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2001–2004, 2016

Published: May 2016

ABSTRACTWe demonstrated a novel self‐oscillating up‐conversion mixer with double‐conversion structure in order to overcome a high conversion loss of a self‐oscillating sub‐harmonic up‐conversion mixer. The self‐oscillating double‐conversion mixer consists of a self‐oscillating up‐conversion mixer and an up‐conversion gate mixer, based on two 100 nm pseudomorphic high electron mobility transistors (PHEMTs). The mixer has an operating frequency of 77 GHz due to the double‐conversion of self‐generated fundamental LO frequency of 38.5 GHz. The mixer exhibits a good conversion gain of 3.87 dB and a phase noise of −92.9 dBc/Hz at 10 MHz offset. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1989–1993, 2016

AbstractBackgroundThe purpose of this study was to evaluate the frequency and characteristics of surgical protocol violations (SPVs) among children undergoing surgery for renal tumors who were enrolled on the Children's Oncology Group (COG) renal tumor biology and classification study AREN03B2.MethodsAREN03B2 was opened in February 2006, and as on March 31, 2013, there were 3,664 eligible patients. The surgical review forms for 3,536 patients with unilateral disease were centrally reviewed for SPVs. The frequency, type, number of violations, institutional prevalence, and quartiles for SPVs were assessed.ResultsOf the 3,536 patients, there were a total of 505 with at least one SPV (564 total SPVs reported), for an overall incidence of 14.28%. The types of SPVs included a lack of lymph node sampling in 365 (64.7%), avoidable spill in 61 (10.8%), biopsy immediately before nephrectomy in 89 (15.8%), an incorrect abdominal incision in 32 (5.7%), and unnecessary resection of organs in 17 (3.0%). The SPVs occurred in 163 of 215 participating institutions (75.8%). For centers with at least one SPV, the mean number of SPVs reported was 3.10 ± 2.39 (mean ± standard deviation). The incidence of protocol violation per institution ranged from 0 to 67%. Centers with an average of ≤1 case/year had an incidence of SPVs of 12.2 ± 3.8%, those with an average of >1 to <4 cases/year had an incidence of SPVs of 16.4 ± 3.6%, and those with an average of ≥4 cases/year had an incidence of SPVs of 12.6 ± 5.5% (P > 0.05).ConclusionsSPVs that potentially result in additional exposure to chemotherapy and radiation therapy are not uncommon in children undergoing resection of renal malignancies.

AbstractPurposeTo evaluate effectiveness and safety of rivaroxaban versus warfarin or dabigatran etexilate in a prospective cohort of routine care non‐valvular atrial fibrillation (AF) patients during February 2012 to August 2014.MethodsWe identified in nationwide health registries a cohort of AF patients who were new‐users of rivaroxaban 15 mg (R15) or 20 mg (R20); dabigatran 110 mg (D110) or 150 mg (D150); or warfarin. Propensity‐adjusted Cox regression was used to compare outcome rates in four settings: ‘R15 vs. warfarin’; ‘R15 vs. D110’; ‘R20 vs. warfarin’; and ‘R20 vs. D150’.ResultsRivaroxaban users (R15: n = 776; R20: n = 1629) were older and with more comorbidities than warfarin (n = 11 045) and dabigatran users (D110: n = 3588; D150: n = 5320). Rivaroxaban 15‐mg users had the overall highest crude mortality rate. After propensity adjustment, rivaroxaban had lower stroke rates vs. warfarin (R15: hazard ratio [HR] 0.46, 95% confidence interval [CI]: 0.26–0.82; R20 HR: 0.72, 95%CI: 0.51–1.01), and similar stroke rates vs. dabigatran. The bleeding rate was similar to warfarin and moderately higher vs. dabigatran (R15 vs. D110 HR: 1.28, 95%CI: 0.82–2.01; R20 vs. D150 HR: 1.81, 95%CI: 1.25–2.62). The mortality rate was higher vs. dabigatran (R15 vs. D110 HR: 1.43, 95%CI: 1.13–1.81; R20 vs. D150 HR: 1.52, 95%CI: 1.06–2.19).ConclusionsRivaroxaban was associated with similar or lower stroke rates, but higher bleeding and mortality rates. Channeling of rivaroxaban towards elderly and less healthy patients may have generated residual confounding. In particular, our findings cannot stand alone when deciding which oral anticoagulant to prescribe. Copyright © 2016 John Wiley & Sons, Ltd.

AbstractObjectiveDepression and anxiety are common in hospitalized patients. In particular, oncological patients might be vulnerable to depression and anxiety. The aim of this study is to assess and compare different variables and the prevalence of anxiety and depression symptoms between oncological and medically ill inpatients and to identify variables that can influence depressive and anxious symptoms during hospitalization of patients.MethodsA total of 360 consecutive hospitalized patients completed the following questionnaires: Hospital Anxiety and Depression Scale (HADS), Patients Health Questionnaire‐9, General Health Questionnaire (GHQ‐12), 12‐Item Short‐Form Survey: physical component summary (PCS), and mental component summary (MCS). Patients were divided into oncological patients and non‐oncological patients: groups 1 and 2.ResultsOnly two significant differences were evident between the groups: the PCS of 12‐item Short‐form Survey was higher in non‐oncological patient (p < 0.000), and the GHQ total score was higher in oncological patients. Variables significantly associated with HADS‐D ≥ 8 were lower MCS, higher GHQ‐12 score, lower PCS, more numerous previous hospitalizations, longer duration of hospitalization, and positive psychiatric family history. Variables significantly associated with HADS‐A ≥ 8 were lower MCS, higher GHQ‐12 score, positive psychiatric family history, longer duration of hospitalization, and younger age.ConclusionsAnxiety and depression symptoms in concurrent general medical conditions were associated with a specific sociodemographic profile, and this association has implications for clinical care.

Exercise preconditioning reduces neonatal incision surgery‐induced enhanced hyperalgesia via inhibition of P38 mitogen‐activated protein kinase and IL‐1β, TNF‐α release
Authors: Gong Xingrui , Jiang Jing , Zhang Mazhong 
Published: May 2016

AbstractNeonatal surgery leads to enhanced hyperalgesia to noxious stimulation in adulthood via a mechanism caused by enhanced phosphorylated (p)‐p38 expression in microglia. We tested the effect of exercise on reducing enhanced hypersensitivity primed by neonatal incision surgery. Adult female Wistar rats, with or without neonatal incision surgery at postnatal day (P) 3, received right hind paw plantar incision surgery under anesthesia at P44. The rats performed wheel‐running exercise from P22 to P41. Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were measured and ipsilateral spinal cords were collected for protein quantification. For PWT and PWL, exercise reduced the pain index after incision surgery at P44 in rats with neonatal surgery (P < 0.01). Western blots showed that exercise suppressed P‐p38 expression relative to adult rats without neonatal surgery (P < 0.05). Results of ELISA showed that exercise reduced IL‐1β and TNF‐α (P < 0.05) concentration in the ipsilateral spinal cord. Exercise preconditioning is an effective approach to reducing enhanced adult hyperalgesia primed by neonatal surgery. The mechanism may be explained by exercise‐induced inhibition of P‐p38 activation and IL‐1β, TNF‐α release.

Published: May 2016

AbstractHospitals need to be fully operative during disasters. It is therefore essential to be able to evaluate hospital preparedness. However, there is no consensus of a standardized, comprehensive and reliable tool with which to measure hospital preparedness. The aim of the current study was to perform a systematic review of evaluation tools for hospital disaster preparedness. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words “crisis,” “disaster,” “disaster medicine,” “emergency,” “mass casualty,” “hospital preparedness,” “hospital readiness,” “hospital assessment,” “hospital evaluation,” “hospital appraisal,” “planning,” “checklist,” and “medical facility” were used in combination with the Boolean operators “OR” and “AND.” PubMed (National Library of Medicine, Bethesda, MD), ISI Web of Science (Thomson Reuters, New York, NY), and Scopus (Elsevier, New York, NY) were searched. A total of 51,809 publications were screened. The following themes were required for relevance: logistics, planning, human resources, triage, communication, command and control, structural and nonstructural preparedness, training, evacuation, recovery after disaster, coordination, transportation, surge capacity, and safety. The results from 15 publications are presented. Fifteen articles fulfilled the criteria of relevance and considered at least 1 of the 14 predetermined themes. None of the evaluated checklists and tools included all dimensions required for an appropriate hospital preparedness evaluation. The results of the current systematic review could be used as a basis for designing an evaluation tool for hospital disaster preparedness. (Disaster Med Public Health Preparedness. 2016;page 1 of 8)

Published: May 2016

AbstractNutritional intakes of food bank recipients and consequently their health status largely rely on the availability and quality of donated food in provided food parcels. In this cross-sectional study, the nutritional quality of ninety-six individual food parcels was assessed and compared with the Dutch nutritional guidelines for a healthy diet. Furthermore, we assessed how food bank recipients use the contents of the food parcel. Therefore, 251 Dutch food bank recipients from eleven food banks throughout the Netherlands filled out a general questionnaire. The provided amounts of energy (19 849 (sd162 615) kJ (4744 (sd38 866) kcal)), protein (14·6 energy percentages (en%)) and SFA (12·9 en%) in a single-person food parcel for one single day were higher than the nutritional guidelines, whereas the provided amounts of fruits (97 (sd1441) g) and fish (23 (sd640) g) were lower. The number of days for which macronutrients, fruits, vegetables and fish were provided for a single-person food parcel ranged from 1·2 (fruits) to 11·3 (protein) d. Of the participants, only 9·5 % bought fruits and 4·6 % bought fish to supplement the food parcel, 39·4 % used all foods provided and 75·7 % were (very) satisfied with the contents of the food parcel. Our study shows that the nutritional content of food parcels provided by Dutch food banks is not in line with the nutritional guidelines. Improving the quality of the parcels is likely to positively impact the dietary intake of this vulnerable population subgroup.

AbstractObjectiveTo determine perceptions, beliefs and experiences affecting breast-feeding in Marshallese mothers residing in Northwest Arkansas, USA.DesignA qualitative, exploratory study using a brief survey and focus groups. Marshallese women, 18 years or older who had a child under 7 years of age, were included in the study.SettingCommunity-based organization in Northwest Arkansas.ResultsThe majority of mothers viewed breast milk as superior to formula, but had concerns about adequate milk supply and the nutritional value of their milk. The primary barriers to exclusive breast-feeding in the USA included public shaming (both verbal and non-verbal), perceived milk production and quality, and maternal employment. These barriers are not reported in the Marshall Islands and are encountered only after moving to the USA. Breast-feeding mothers rely heavily on familial support, especially the eldest female, who may not reside in the USA. The influence of institutions, including the Special Supplemental Nutrition Program for Women, Infants, and Children, is strong and may negatively affect breast-feeding.ConclusionsDespite the belief that breast milk is the healthiest option, breast-feeding among Marshallese mothers is challenged by numerous barriers they encounter as they assimilate to US cultural norms. The barriers and challenges, along with the strong desire to assimilate to US culture, impact Marshallese mothers’ perceptions, beliefs and experiences with breast-feeding.

AbstractThe central issue in the physics of cuprate superconductivity is the mutual relationship among superconductivity, pseudogap and broken-spatial-symmetry states. A magnetic field B suppresses superconductivity, providing an opportunity to investigate the competition among these states. Although various B-induced electronic superstructures have been reported, their energy, spatial and momentum-space structures are unclear. Here, we show using spectroscopic-imaging scanning tunnelling microscopy on Bi2Sr2CaCu2O8+δ that there are two distinct B-induced electronic superstructures, both being localized in the vortex core but appearing at different energies. In the low-energy range where the nodal Bogoliubov quasiparticles are well-defined, we observe the so-called vortex checkerboard that we identify as the B-enhanced quasiparticle interference pattern. By contrast, in the high-energy region where the pseudogap develops, the broken-spatial-symmetry patterns that pre-exist at B=0 T is locally enhanced in the vortex core. This evidences the competition between superconductivity and the broken-spatial-symmetry state that is associated with the pseudogap.

AbstractAlthough the association of hyperuricemia and cardiovascular diseases is well established by previous research studies, the relationship between gout and deep vein thrombosis (DVT) remains unclear. We conducted a nationwide longitudinal cohort study to investigate the relationship between gout and DVT. We used the Taiwan National Health Insurance Research Database to identify patients with gout diagnosed in Taiwan during 2000–2011, and we followed up these patients to determine the incidence of DVT among them. The association between gout and DVT was analyzed by cox proportional hazard model. The study cohort included 35,959 patients with history of gout attack and 35,959 matched controls without gout attack. During the median follow-up of 7.5 ± 3.6 years, the incidence rate of DVT was significantly higher in patients with gout than that in control group (13.48 versus 9.77 per 104 person-years, p < 0.001). Kaplan-Meier analysis revealed a tendency toward DVT development in gout patients (log rank test, p < 0.001). In a Cox model, patients with gout were found to have a 1.38-fold (95% confidence interval [CI], 1.18 to 1.62, p < 0.001) higher risk of developing DVT. Hyperuricemia with gout attack could be a possible risk predictor for DVT, but these findings need to be confirmed in future clinical and experimental studies.

Published: May 2016

AbstractIn this paper, we developed a novel approach for interfacing a microfluidic two-dimensional droplet array to a high-speed capillary electrophoresis (HSCE) system. Picoliter-scale sample injection (ca. 200 pL) from a nanoliter-scale droplet array covered by nonvolatile oil was automatically achieved using the spontaneous injection mode, without the interference from the cover oil and the need of special droplet extraction interface as in previously reported systems. The system was applied in consecutive separations of 25 different samples of amino acids with a whole separation time less than 15 min, as well as on-line monitoring of in-droplet derivatizing reaction of amino acids by fluorescein isothiocyanate (FITC) over 3 hours. High separation speed (up to 100 samples per hour) and high separation efficiency (up to 9.22 × 105 N/m) were achieved.
Tunable Band-Stop Filters for Graphene Plasmons Based on Periodically Modulated Graphene

Published: May 2016

AbstractTunable band-stop filters based on graphene with periodically modulated chemical potentials are proposed. Periodic graphene can be considered as a plasmonic crystal. Its energy band diagram is analyzed, which clearly shows a blue shift of the forbidden band with increasing chemical potential. Structural design and optimization are performed by an effective-index-based transfer matrix method, which is confirmed by numerical simulations. The center frequency of the filter can be tuned in a range from 37 to 53 THz based on the electrical tunability of graphene, while the modulation depth (−26 dB) and the bandwidth (3.1 THz) of the filter remain unchanged. Specifically, the bandwidth and modulation depth of the filters can be flexibly preset by adjusting the chemical potential ratio and the period number. The length of the filter (~750 nm) is only 1/9 of the operating wavelength in vacuum, which makes the filter a good choice for compact on-chip applications.

AbstractLow back pain (LBP) is a common debilitating condition which aetiology and pathogenesis are poorly understood. We carried out a first so far analysis of associations between LBP and plasma IgG N-glycome in a sample of 4511 twins from TwinsUK database assessed for LBP, lumbar disc degeneration (LDD) as its possible cause, and IgG-glycan levels. Using weighted correlation network analysis, we established a correlation between LBP and glycan modules featured by glycans that either promote or block antibody-dependent cell-mediated cytotoxicity (ADCC). The levels of four glycan traits representing two of those modules were statistically significantly different in monozygotic twins discordant for LBP. Also, the trend to higher prevalence of systemic inflammatory disorders was shown for twins with low level of fucosylated glycans and high level of non-fucosylated glycans. Core fucosylation of IgG is a “safety switch” reducing ADCC, thus our results suggest the involvement of ADCC and associated inflammation in pathogenesis of LBP. No correlation between LDD scores and glycans was found assuming that the inflammation may not be a part of LDD. These data provide a new insight into understanding the complex pathophysiology of LBP and suggest glycan levels as a possible biomarker for inflammation-related subtypes of LBP.
