Published: July 2017

AbstractRealizing energy harvesting from water flow using triboelectric generators (TEGs) based on our daily wearable fabric or textile has practical significance. Challenges remain on methods to fabricate conformable TEGs that can be easily incorporated into waterproof textile, or directly harvest energy from water using hydrophobic textile. Herein, a wearable all‐fabric‐based TEG for water energy harvesting, with additional self‐cleaning and antifouling properties is reported for the first time. Hydrophobic cellulose oleoyl ester nanoparticles (HCOENPs) are prepared from microcrystalline cellulose, as a low‐cost and nontoxic coating material to achieve superhydrophobic coating on fabrics, including cotton, silk, flax, polyethylene terephthalate (PET), polyamide (nylon), and polyurethane. The resultant PET fabric‐based water‐TEG can generate an instantaneous output power density of 0.14 W m−2 at a load resistance of 100 MΩ. An all‐fabric‐based dual‐mode TEG is further realized to harvest both the electrostatic energy and mechanical energy of water, achieving the maximum instantaneous output power density of 0.30 W m−2. The HCOENPs‐coated fabric provides excellent breathability, washability, and environmentally friendly fabric‐based TEGs, making it a promising wearable self‐powered system.

AbstractObjectives of the present study were to identify predictors of the recurrence of intrahepatic cholangiocarcinoma (ICC), and to evaluate the survival benefit of adjuvant chemotherapy and surgical treatment for ICC recurrence. A multi‐institutional retrospective study was carried out in 356 patients with ICC who underwent curative surgery at one of 14 institutions belonging to the Kyushu Study Group of Liver Surgery. A total of 214 patients (60%) had recurrence. Predictors of ICC recurrence were as follows: positive for pathological intrahepatic metastasis (im), positive for lymph node metastasis (n), positive for pathological lymphatic infiltration (ly), pathological bile duct invasion (b), and tumor size ≥4.4 cm. Adjuvant chemotherapy was given to 120 patients (34%) and, in the patients with im or tumor size ≥4.4 cm, adjuvant chemotherapy showed a survival benefit. Only 37 patients (17%) underwent surgical treatment for ICC recurrence. The surgical treatment resulted in a good 5‐year survival rate (44%), which is similar to the rate obtained by the first operation for primary ICC. Prognosis of patients with primary im after the second operation was significantly worse (5‐year survival 18%) compared to patients without primary im. Primary im+ should be considered a contraindication for surgical treatment for ICC recurrence.

Published: July 2017

AbstractSurgical resection for distal cholangiocarcinoma is usually carried out using pancreaticoduodenectomy (PD). However, because PD is a complex procedure with a high rate of postoperative complications, the surgical indications should be carefully considered, especially for patients with a decreased performance status, significant comorbidities, and/or anatomical anomalies. If curatively carried out, a less invasive, local resection may be an alternative procedure for such patients. In the current study, we present pancreas‐preserving resection of the lower biliary tract in a patient with early‐stage distal cholangiocarcinoma. This procedure was selected to avoid PD with arterial reconstruction because of arterial anomalies. After an abdominal exploration, a cholecystectomy was carried out and the common hepatic duct was transected. The bile duct was dissected from the pancreatic parenchyma without pancreatic resection, downward to the biliopancreatic ductal confluence. Next, a duodenotomy was done opposite Vater's ampulla. The duodenal mucosa around Vater's ampulla was incised and dissected, and the main pancreatic duct (MPD) was divided. The bile duct was completely separated from the pancreatic parenchyma, and the lower biliary tract was totally “cored‐out”. After resection, the MPD was re‐implanted into the duodenal wall, and the duodenotomy was closed. Finally, a Roux‐en‐Y hepaticojejunostomy was created. Postoperative course was uneventful. No tumor recurrence has been observed for 21 months after the operation. Thus, pancreas‐preserving resection of the lower biliary tract appeared to be appropriate for our patient. This organ‐preserving approach can be a useful, alternative procedure in selected patients.

AbstractConsiderable attention has been focused on nonalcoholic fatty liver disease (NAFLD) which occasionally develops after pancreatoduodenectomy (PD). The present study aimed to clarify the prevalence, sequential change in properties and risk factors for NAFLD development after PD. We enrolled 196 patients who underwent PD and a computed tomography (CT) scan 1 month, 6 months and 1 year after surgery. NAFLD was defined as a liver‐to‐spleen attenuation ratio on plain CT of <0.9. We compared various clinical factors between the NAFLD group and the control group. Individual prevalence of NAFLD at 1 month, 6 months and 1 year after surgery was 12%, 21% and 15%. Significantly different factors by univariate analysis were as follows: 1 month: age, sex, total protein (TP), total cholesterol (TC) and copper (Cu); 6 months: sex, disease, surgical method, portal vein resection (PVR), frequency of defecation, TC and Cu; 1 year: age, sex, disease, surgical method, PVR, frequency of defecation, TP and Cu. Risk factors by multivariate analysis were as follows: 1 month: not elderly age, female sex and a decrease in Cu; 6 months: female sex and a decrease in Cu; 1 year: a decrease in Cu. NAFLD after PD frequently developed in women with a decrease in serum Cu and was influenced by various factors related to poor digestion and absorption associated with pancreatic exocrine insufficiency.
C(sp2)−O Bond Formation through a Nickel‐Catalyzed Cross‐Coupling Reaction in Water Enabled by Micellar Catalysis

Published: July 2017

AbstractA nickel‐catalyzed cross‐coupling reaction between (functionalized) aryl chlorides and alcohols that results in C(sp2)−O bond formation is described. This procedure further develops the nickel‐catalyzed nucleophilic substitution of aryl chlorides with water. Despite the intolerance of transition‐metal catalysis to water, the use of nickel reagents, including their formation and use in an aqueous micellar environment, are discussed herein. The PCy3 ligand, surfactant, and nickel catalyst were all found to be important for C−O bond formation. Various types of aromatic and aliphatic alcohols were tolerated in this reaction, thereby affording a range of ethers in high yields and selectivities.

Published: July 2017

AbstractAtomic‐scale mechanochemistry is realized from force exerted by a C60‐functionalized scanning tunneling microscope tip. Two conformers of tin phthalocyanine can be prepared on coinage‐metal surfaces. A transition between these conformers is induced on Cu(111) and Ag(100). Density‐functional calculations reveal details of this reaction. Because of the large energy barrier of the reaction and the strong interaction of SnPc with Cu(111), the process cannot be achieved by electrical means.

Published: July 2017

AbstractScrew dislocation structures in crystals are an origin of symmetry breaking in a wide range of dense‐phase crystals. Preparation of such analogous structures in framework‐phase crystals is of great importance in zeolites but is still a challenge. On the basis of crystal‐structure solving and model building, it was found that the two specific intergrowths in MTW zeolite produce this complex fractal and spiral structure. With the structurally determined parameters (spiral pitch h, screw angle θ, and spatial angle ψ) of Burgers circuit, the screw dislocation structure can be constructed by two different dimensional intergrowth sections. Thus the reported complexity of various dimensions in diverse crystals can be unified.

The present study deals with the synthesis and characterization (FE‐SEM, particle size distribution, XRD and point of zero charge) SnO2/(NH4)2‐SnCl6 nanocomposites loaded on activated carbon (SnO2/(NH4)2‐SnCl6‐NCs‐AC) and its subsequent application for the simultaneous removal of Methylene Blue (MB) and Orange G (OG) from aqueous solution. Response surface methodology (RSM) based on central composite design (CCD) give trend of influencing responses with respect to five parameters such as contact time (X1), OG concentration (X2), MB concentration (X3), adsorbent mass (X4) and pH (X5). In later stage following recognition of significant variables and interaction, quadratic model generated which are able to predict the dyes removal in different conditions. Justification and selection of significant terms was conducted based on analysis of variance and Fisher's F‐test Optimal value of contact time, OG concentration, MB concentration, adsorbent mass and pH were set at 4.0 min, 10 mg l−1, 20 mg L−1, 0.015 g and 6.0, respectively, which lead to achievement of best experiment removal percentage of 97.0 and 99.5% OG and MB respectively, from their binary solutions. The whole experimental data follow pseudo‐first‐order and pseudo‐second‐order rate equations. The fitting experimental data to more available conventional model like Langmuir, Freundlich, Temkin and Dubinin‐Radushkevich isotherm models revel more ability of Langmuir model (with R2 > 0.997) for explanation of system in equilibrium. The adsorption efficiency remained high even after the five cycle of reuse (99.76% and 95.56% for MB and OG, respectively).

Published: July 2017

ABSTRACTIn this study, antibacterial and electrically conductive polyacrylonitrile (PAN) fibers were prepared by one‐step reaction between Cu2+ and S2– ions without extra reducing agents. The copper sulfide layer was firmly adhered to PAN fibers with the help of nitrile groups from PAN fibers and chelating agent of ethylenediaminetetraacetic acid disodium salt. The copper sulfide layer was characterized by scanning electron microscopy, transmission electron microscopy, energy‐dispersive spectrometry, X‐ray diffraction, Raman and X‐ray photoelectron spectroscopy. The results illustrated that a compact and uniform copper sulfide layer was coated on PAN fibers with 108 nm thickness, and it was proved to be a pure hexagonal phase of covellite structure. The average resistance of the resultant fibers was about 360 Ω/cm and the mass content of copper sulfide was about 13.3%. The antibacterial tests demonstrated that the resultant fibers exhibited excellent antibacterial properties with antibacterial efficiency of 99.99% against Staphylococcus aureus and 96.80% against Escherichia coli. Furthermore, the antibacterial activities and electrical conductivity still remain good after 30 cycles of standard washing, indicating their good durability when in use. © 2017 Wiley Periodicals, Inc.

AbstractDer Beitrag thematisiert das BMBF‐geförderte Projekt „KaWaTech“, welches auf die Entwicklung und Umsetzung innovativer Wasserförder‐ und ‐verteilkonzepte für sub‐/tropische (Karst‐)Regionen abzielt. Unter anderem wird in der Provinz Ha Giang eine Pilotwasserförderanlage realisiert, welche die Versorgung von ca. 10 000 Menschen sicherstellen soll. Als Bypasslösung für Wasserkraftanlagen dient sie der Nutzbarmachung der für den Turbinenbetrieb nicht effizient verwertbaren Restwassermengen während der Trockenzeit über ein wasserkraftbetriebenes Pumpsystem. Neben der Implementierung der Maschinentechnik wurden umfassende Sanierungsmaßnahmen an der wasserbaulichen Infrastruktur umgesetzt. In diesem Zusammenhang wurden auch baustofftechnologische Untersuchungen zu optimierten Betonrezepturen auf Basis lokaler Ausgangsstoffe durchgeführt.Das geförderte Wasser wird in einen zentralen Hochbehälter eingespeist und den umliegenden Siedlungen und der Distrikthauptstadt gravitär zur Verfügung gestellt. Um eine gerechte Verteilung zu ermöglichen, wurde ein flexibles Verteilungskonzept zur Berücksichtigung dynamischer Dargebotsschwankungen entwickelt. Zudem wurde die Angliederung des neuen Verteilsystems an das bestehende Leitungsnetz der Distrikthauptstadt mittels eines adaptiven Druckmanagements entworfen.

Published: July 2017

AbstractExploring advanced anode materials with highly reversible capacity have gained great interests for large‐scale lithium storage. A facile two‐step method is developed to synthesize nitrogen‐doped carbon coated MoSe2 microspheres via hydrothermal plus thermal polymerization. The MoSe2 microspheres composed of interconnected nanoflakes are homogeneously coated by a thin nitrogen‐doped carbon (N‐C) layer. As an anode for lithium ion batteries, the MoSe2/N‐C composite shows better reversibility, smaller polarization, and higher electrochemical reactivity as compared to the unmodified MoSe2 microspheres. The MoSe2/N‐C electrode delivers a high specific capacity of 698 mAh g−1 after 100 cycles at a current density of 100 mA g−1 and good high rate performance (471 mAh g−1 at a high current density of 2000 mA g−1). The improved electrochemical performance is attributed to the conductive N‐C coating and hierarchical microsphere structure with fast ion/electron transfer characteristics.
The role of medical/nursing skills training in caregiver confidence and burden: A CanCORS study
Authors: Mollica Michelle A. , Litzelman Kristin , Rowland Julia H. , Kent Erin E. 
Published: July 2017

BACKGROUNDInformal cancer caregivers provide essential support to cancer patients, including performing direct medical/nursing tasks, assisting with activities of daily living, and offering social support. This study examined associations between the receipt of medical/nursing skills training and the caregiver burden as well as the mediation of caregiving confidence on this relationship in a sample of caregivers of lung and colorectal cancer patients.METHODSCaregivers who had been identified by cancer patients in the Cancer Care Outcomes Research and Surveillance consortium completed a questionnaire assessing the care provided, the type of medical/nursing skills training received, the burden (measured with the modified short‐form Zarit Burden Interview), and the confidence in caring for their patient's physical needs. Regression models that had been adjusted for sociodemographic, caregiver, and care recipient characteristics assessed the relationship between training received and burden, and a mediation analysis assessed the role of confidence in this relationship.RESULTSSix hundred forty‐one caregivers performed some type of medical/nursing task, with 59% (n = 377) reporting that they did not receive training for all the care provided. Caregivers reported moderate levels of burden (mean summary score, 32.07; standard deviation, 12.66; possible range, 14‐70), and a lack of receipt of training was associated with greater levels of burden (b = 2.60; standard error, 0.98; P = .01). Confidence partially mediated the relation between training and burden (Sobel's t = 1.90; P = 0.03).CONCLUSIONSAs the number of cancer patients and caregivers increases, understanding how best to reduce the caregiver burden is necessary. Skills training is a potential area for interventions, but research on how best to provide training for caregivers (ie, the content, mode of delivery, and timing) is needed.

Published: July 2017

BACKGROUNDThe National Quality Forum has endorsed quality‐improvement measures for multiple cancer types that are being developed into actionable tools to improve cancer care. No nationally endorsed quality metrics currently exist for head and neck cancer.METHODSThe authors identified patients with surgically treated, invasive, head and neck squamous cell carcinoma in the National Cancer Data Base from 2004 to 2014 and compared the rate of adherence to 5 different quality metrics and whether compliance with these quality metrics impacted overall survival. The metrics examined included negative surgical margins, neck dissection lymph node (LN) yield ≥ 18, appropriate adjuvant radiation, appropriate adjuvant chemoradiation, adjuvant therapy within 6 weeks, as well as overall quality.RESULTSIn total, 76,853 eligible patients were identified. There was substantial variability in patient‐level adherence, which was 80% for negative surgical margins, 73.1% for neck dissection LN yield, 69% for adjuvant radiation, 42.6% for adjuvant chemoradiation, and 44.5% for adjuvant therapy within 6 weeks. Risk‐adjusted Cox proportional‐hazard models indicated that all metrics were associated with a reduced risk of death: negative margins (hazard ratio [HR] 0.73; 95% confidence interval [CI], 0.71‐0.76), LN yield ≥ 18 (HR, 0.93; 95% CI, 0.89‐0.96), adjuvant radiation (HR, 0.67; 95% CI, 0.64‐0.70), adjuvant chemoradiation (HR, 0.84; 95% CI, 0.79‐0.88), and adjuvant therapy ≤6 weeks (HR, 0.92; 95% CI, 0.89‐0.96). Patients who received high‐quality care had a 19% reduced adjusted hazard of mortality (HR, 0.81; 95% CI, 0.79‐0.83).CONCLUSIONSFive head and neck cancer quality metrics were identified that have substantial variability in adherence and meaningfully impact overall survival. These metrics are appropriate candidates for national adoption. Cancer 2017;123:4372‐81. © 2017 American Cancer Society.
