Examining the Factor Structure and Reliability of the Safe Patient Handling Perception Scale: An Initial Validation Study
Authors: White-Heisel Regina , Canfield James P. , Young-Hughes Sadie 
Published: February 2016

Abstract

Purpose:
Perceiving imminent safe patient handling and movement (SPH&M) dangers may reduce musculoskeletal (MSK) injuries for nurses in the workplace. The purpose of this study is to develop and validate the 17-item Safe Patient Handling Perception Scale (SPHPS) as an evaluation instrument assessing perceptual risk of MSK injury based on SPH&M knowledge, practice, and resource accessibility in the workplace.

Methods:
Data were collected from a convenience sample (N = 117) of nursing employees at a Veteran Affairs Medical Center. Factor analysis identified three factors: knowledge, practice, and accessibility.

Findings:
The SPHPS demonstrated high levels of reliability, supported by acceptable alpha scores (SPHM knowledge [α = .866], SPHM practices [α = .901], and access to SPHM resources [α = .855]), in addition to the relatively low standard error of measurement scores (SEM).

Conclusion:
The study outcomes suggest that the SPHPS is a valid and reliable tool that can measure participants’ perceived risk factors for MSK injuries.
Self–confined synthesis of HKUST‐1 membranes from CuO nanosheets at room temperature

Published: February 2016

AbstractMetal‐organic frameworks (MOFs) have drawn great interest in several applications. MOFs can be successfully synthesized by metal oxide or hydroxide, but the synthesis of MOFs membranes has been rarely reported. Here we found the CuO nanosheets (CuO NSs) were highly positively charged and reactive enough to form HKUST‐1 powders in trimesic acid (H3BTC) ethanol‐water solution even at room temperature. Thus we design a self‐confined and healing strategy to prepared well‐intergrown HKUST‐1 membranes on macroporous support by solid‐to‐solid conversion from CuO NSs film. During the growth process, HKUST‐1 (Cu3(BTC)2⋅3H2O) crystals are self‐confined and tightly intergrown. The gaps and defects are healed with elongation growth time, resulting in a continuous and well‐intergrown HKUST‐1 membrane. The continuous and well intergrown HKUST‐1 thin membranes demonstrate good gas separation performance. The process presented here may pave a new way to prepare MOFs membranes by using active metal oxide nanostructures.
Dicyanomethylene‐benzopyran‐based alkynyl conjugatable near–infrared fluorescent probe for detection of fluoride anion

Published: February 2016

AbstractNear‐infrared (NIR) fluorophore with one functional group, which can be utilized to conjugate other molecules, could meet various requirements just through structural modification, such as for regulating their subtle equilibrium between hydrophilicity and lipophilicity. Herein, considering the favorable photophysical properties of dicyanomethylene‐benzopyran (DCMB) derivatives and the orthogonality of functional groups and the excellent biocompatibility of CuI‐catalyzed click chemistry, the synthesis of azido and phenolic hydroxyl‐bifunctionalized DCMB‐based compound N3‐DCMBOH is described, which can conjugate with other molecules by click chemistry. As a preliminary exploration, tert‐butyldiphenylsilyl group and alkynyl‐contained quaternary ammonium were successively conjugated onto N3‐DCMBOH to construct NIR fluorescent sensor QA‐DCMBSi for detection of F−. The dramatic absorption band change with 196 nm red shift and distinct NIR fluorescence enhancement at 718 nm, can be attributed to F− mediated cleavage of silicon‐oxygen bond to release QA‐DCMBOH, which was verified by MS spectrum.
Effects of connection flexibility in bridge girders under moving loads
Authors: Machelski Czesław , Toczkiewicz Robert 
Published: February 2016

AbstractThis paper looks at the problem of connection flexibility in steel‐concrete bridge girders under moving loads. The static action of the load changing location on the structure is considered. An analytical model of the girder is used assuming strain discontinuity at the steel‐concrete interface as a result of beam‐plate partial interaction. The effects of a flexible connection are characterized by the proposed index defined on the basis of the internal forces in the girder. This index can be calculated during loading tests on the basis of the neutral axis position at the section of the girder considered. Numerical analyses show that values of the index characterizing beam‐plate interaction depend on the position of the load on the structure and the function describing connection stiffness.
Circular hollow through plate connections
Authors: Voth Andrew P. , Packer Jeffrey A. 
Published: February 2016

AbstractThis article reviews prior research on connections between through‐plates and circular hollow sections (CHS) and presents a finite element (FE) study validated against laboratory experiments. The FE analysis indicates that, for a given geometric configuration, the behaviour of through‐plate‐to‐CHS connections closely matches the sum of branch‐plate‐to‐CHS connection behaviour in plate tension and compression. A connection design strength, which is shown to be valid for a wide range of connection geometries and which is the sum of existing design recommendations for branch plate‐to‐CHS connections loaded in axial tension and compression, is hence proposed for through‐plate‐to‐CHS T‐connections. This therefore enables maximum advantage to be taken of the capacity of this type of “reinforced” tubular connection.
Design of single‐span beams for SLS and ULS using semi‐continuous beam‐to‐column joints
Authors: Braun Matthias , da Costa Job Duarte , Obiala Renata , Odenbreit Christoph 
Published: February 2016

AbstractThis article explains a method for determining how semi‐continuous joints influence the deflection, natural frequency and bending moment distribution of single‐span beams with constant inertia under uniformly distributed load. The method is adequate for simple hand calculations, allowing the structural engineer to assess potential savings already in the pre‐design phase. Further, the economical potential of semi‐continuous joints according to EN 1993‐1‐8 [1] is demonstrated by an application example.
Simple Bridges

Published: February 2016

AbstractMany famous footbridges show have a spectacular, eye‐catching design or functionality. They feature extravagant structures, large spans or outstanding locations and they are globally published and widely discussed amongst professionals and laymen.However, there are smaller and simpler bridges, whose good and appropriate design, structural behaviour and sustainability can only be seen at the second look. While not having showy features they are beautiful, reasonable, efficient, sometimes trendsetting but always interesting enough to justify careful attention.This paper presents five bridges – designed by schlaich bergermann partner, completed within the past few years – that are characterized especially by their apparent simplicity: a simple beam bridge in Backnang, three arch bridges in Dortmund, a prestressed concrete beam bridge in Hamburg, a two‐span stress ribbon bridge in Schwäbisch Gmünd and a fixed‐end beam bridge in Esslingen.
Punching shear strength of flat slabs – critical review of Eurocode 2 and fib Model Code 2010 design provisions
Authors: Ricker Marcus , Siburg Carsten 
Published: February 2016

AbstractThe fib Model Code for Concrete Structures 2010 introduces a new design concept for punching shear based on critical shear crack theory. This paper presents and provides the background to the design provisions for punching shear according to fib Model Code 2010, Eurocode 2 and the corresponding German National Annex to Eurocode 2. The different punching shear design provisions are critically reviewed by means of parameter studies and a comparison of the calculated resistances and test results. The safety levels of the code provisions are verified and the influence of the different punching parameters on the calculated resistances is examined in detail.
Numerical limit analysis of keyed shear joints in concrete structures
Authors: Herfelt Morten A. , Poulsen Peter N. , Hoang Linh C. , Jensen Jesper F. 
Published: February 2016

AbstractThis paper concerns the shear capacity of keyed joints that are transversely reinforced with overlapping U‐bar loops. It is known from experimental studies that the discontinuity of the transverse reinforcement affects the capacity and the failure mode. However, to the best knowledge of the authors, previous theoretical works and current design equations in standards do not account for this important effect. This paper introduces a detailed model based on finite element limit analysis to assess the effect of the discontinuous reinforcement. The model is based on the lower bound theorem and uses the modified Mohr‐Coulomb yield criterion, which is formulated for second‐order cone programming. The model provides a statically admissible stress field as well as the failure mode. Twenty‐four different test specimens were modelled and the calculations compared with the experimental results. The results of the model show satisfactory agreement with the experimental observations. The model produces estimates of the shear capacity that are significantly better than those of the Eurocode 2 design equations.

AbstractIntroductionSevere acute pancreatitis may be complicated by intra‐abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and intestinal ischemia. The aim of this retrospective study is to describe the incidence, treatment, and outcome of patients with severe acute pancreatitis and ACS, in particular the occurrence of intestinal ischemia.MethodsThe medical records of all patients admitted with severe acute pancreatitis admitted to the ICU of a tertiary referral center were reviewed. The criteria proposed by the World Society of the Abdominal Compartment Syndrome (WSACS) were used to determine whether patients had IAH or ACS.ResultsFifty‐nine patients with severe acute pancreatitis were identified. Intra‐abdominal pressure (IAP) measurements were performed in 29 patients (49.2 %). IAH was present in all patients (29/29). ACS developed in 13/29 (44.8 %) patients. Ten patients with ACS underwent decompressive laparotomy. A large proportion of patients with ACS had intra‐abdominal ischemia upon laparotomy: 8/13 (61.5 %). Mortality was high in both the ACS group and the IAH group.ConclusionThis study confirms that ACS is common in severe acute pancreatitis. Intra‐abdominal ischemia occurs in a large proportion of patients with ACS. Swift surgical intervention may be indicated when conservative measures fail in patients with ACS. National and international guidelines need to be updated so that routine IAP measurements become standard of care for patients with severe acute pancreatitis in the ICU.

Abstract
Prophage vB_LdeS-phiJB (phiJB) was induced by mitomycin C and UV radiation from the Lactobacillus delbrueckii subsp. bulgaricus SDMCC050201 isolated from a Chinese yoghurt sample. It has an isometric head and a non-contractile tail with 36,969 bp linear double-stranded DNA genome, which is classified into the group a of Lb. delbrueckii phages. The genome of phiJB is highly modular with functionally related genes clustered together. Unexpectedly, there is no similarity of its DNA replication module to any phages that have been reported, while it consists of open-reading frames homologous to the proteins of Lactobacillus strains. Comparative genomic analysis indicated that its late gene clusters, integration/lysogeny modules and DNA replication module derived from different evolutionary ancestors and integrated into a chimera. Our results revealed a novel chimeric phage of commercial Lb. delbrueckii and will broaden the knowledge of phage diversity in the dairy industry.

AbstractTetrahydrobiopterin (BH4) is an essential cofactor for the aromatic amino acid hydroxylases, alkylglycerol monooxygenase, and nitric oxide synthases (NOS). Inborn errors of BH4 metabolism lead to severe insufficiency of brain monoamine neurotransmitters while augmentation of BH4 by supplementation or stimulation of its biosynthesis is thought to ameliorate endothelial NOS (eNOS) dysfunction, to protect from (cardio‐) vascular disease and/or prevent obesity and development of the metabolic syndrome. We have previously reported that homozygous knock‐out mice for the 6‐pyruvolytetrahydropterin synthase (PTPS; Pts‐ko/ko) mice with no BH4 biosynthesis die after birth. Here we generated a Pts‐knock‐in (Pts‐ki) allele expressing the murine PTPS‐p.Arg15Cys with low residual activity (15 % of wild‐type in vitro) and investigated homozygous (Pts‐ki/ki) and compound heterozygous (Pts‐ki/ko) mutants. All mice showed normal viability and depending on the severity of the Pts alleles exhibited up to 90 % reduction of PTPS activity concomitant with neopterin elevation and mild reduction of total biopterin while blood L‐phenylalanine and brain monoamine neurotransmitters were unaffected. Yet, adult mutant mice with compromised PTPS activity (i.e., Pts‐ki/ko, Pts‐ki/ki or Pts‐ko/wt) had increased body weight and elevated intra‐abdominal fat. Comprehensive phenotyping of Pts‐ki/ki mice revealed alterations in energy metabolism with proportionally higher fat content but lower lean mass, and increased blood glucose and cholesterol. Transcriptome analysis indicated changes in glucose and lipid metabolism. Furthermore, differentially expressed genes associated with obesity, weight loss, hepatic steatosis, and insulin sensitivity were consistent with the observed phenotypic alterations. We conclude that reduced PTPS activity concomitant with mildly compromised BH4‐biosynthesis leads to abnormal body fat distribution and abdominal obesity at least in mice. This study associates a novel single gene mutation with monogenic forms of obesity.

AbstractBackground and objectivesPompe disease is a rare metabolic disorder due to lysosomal alpha‐glucosidase (GAA) deficiency. It is considered as a multi‐systemic disease since, although glycogen accumulation is largely prominent in heart, skeletal and respiratory muscles, other organs can also be affected. As regards the vascular system, few reports have documented cerebrovascular malformations in Pompe patients. The aim of this study was to define the presence and type of intracranial arterial abnormalities in a cohort of late onset Pompe disease (LOPD) patients.MethodsWe have studied 21 LOPD patients with cerebral CT angiography (CTA), using maximum intensity projection and volume rendering technique for 3D‐image reconstruction.ResultsWe found intracranial arterial abnormalities in 13/21 patients (62 %), of whom: 2/21 patients (9.5 %) showed an unruptured intracranial aneurysm (respectively 2 and 4 mm), 10/21 (47 %) had a vertebrobasilar dolichoectasia (VBD) and 1/21 a basilar artery fenestration. Signs of lacunar encephalopathy (insular, capsular and frontal subcortical lesions) were detected in 13/21 patients (62 %) and this correlated with the presence of respiratory impairment (p = 0.017).ConclusionsThese findings differ from what has been previously observed in healthy, aged‐matched populations and confirm that cerebral arteries abnormalities, mainly involving the posterior circle, are not so rare in LOPD patients and are often accompanied by a lacunar encephalopathy that might represent a hypoxic‐ischemic origin. A CTA or an MRA is recommended, in LOPD patients, for early detection of cerebrovascular malformations as they could lead to life‐threatening events such as sub‐arachnoid haemorrhage or brainstem compression.

AbstractPeat swamp forest is an important refuge for biodiversity in Southeast Asia and is now becoming a target of exploitation. The scarcity of information on avifauna and ecology of birds in peat swamp forests prevents understanding of the effects of land use change on avifauna. In this study, we describe the bird assemblages in habitats with different land uses by comparing species richness, community composition, and feeding guild patterns in Bukit Batu, Indonesia. Bird assemblages in natural peat swamp forests (NPF), high‐maintenance industrial acacia plantations (planted acacia forest, PAF), low‐maintenance rubber plantations (jungle rubber forest, JRF), and village areas (VIL) were studied using a fixed‐radius point‐count method. Of the 95 species observed, 45, 20, 35, and 48 species were observed in NPF, PAF, JRF, and VIL, respectively. Estimated species richness was the highest in NPF, followed by VIL, JRF, and PAF. NPF had the highest species diversity and β‐diversity, more endangered species, and a distinctive species composition characterized by fly‐catching insectivores. The relative conservation value of PAF was notably low, particularly compared with JRF. The avifauna in VIL was characterized by more generalists that favor open spaces and therefore is not considered an important habitat for forest‐dependent birds that are of conservation concern. Our results indicate that NPF has irreplaceable value for bird diversity conservation, but low‐maintenance rubber plantations were home to several forest‐dependent species and partially supported bird diversity, particularly compared with high‐maintenance acacia plantations.

AbstractA novel itaconate‐based surfactant, namely sodium n‐octyl sulfoitaconate diester (SOSID), has been synthesized from itaconic acid (IA) and n‐octanol by sulfonation and esterification reaction processes. The effects of reaction temperature, reaction time, molar ratios of n‐octanol to IA and the catalyst dosage on the esterification were investigated. The chemical structure of the surfactants SOSID was characterized by means of LC–MS and confirmed by FT‐IR and 1H NMR spectroscopy. The surface tension γ and the critical micelle concentration (CMC) were determined as 25.02 mN/m and 4.0 × 10−4 mol/L by using surface tensiometer at 20 °C. Further investigations showed that SOSID possess excellent wetting, emulsifying and lime soap dispersing properties.

AbstractObjectiveOn November 8, 2013, Typhoon Haiyan (Yolanda) made landfall in the Philippines. The literature characterizing the medical, surgical, and obstetrics burden following typhoons is lacking. This study aimed to improve disaster preparedness by analyzing medical diagnoses presenting to a city district hospital before, during, and after Typhoon Haiyan.MethodsThe assessment of disease burden and trends was based on logbooks from a local hospital and a nongovernmental organization field hospital for the medicine, surgical, and obstetrics wards before, during, and after the typhoon.ResultsThe hospital provided no services several days after typhoon impact, but there was an overall increase in patient admissions once the hospital reopened. An increase in gastroenteritis, pneumonia, tuberculosis, and motor vehicle collision-related injuries was seen during the impact phase. A dengue fever outbreak occurred during the post-impact phase. There was a noticeable shift in a greater percentage of emergent surgical cases performed versus elective cases during the impact and post-impact phases.ConclusionOverall, several public health measures can prevent the increase in illnesses seen after a disaster. To prepare for the nonfatal burden of disease after a typhoon, health care facilities should increase their resources to accommodate the surge in patient volume.

AbstractObjectiveThis study aimed to examine the effect of Hurricane Sandy on Long Island mental health emergency department (ED) visits and to determine whether these visits varied according to patient demographics or geographic area and intensity of the impact.MethodsIndividual-level de-identified data were extracted from the Statewide Planning and Research Cooperative System from New York State ED visits from October 1 to December 2012 for residents of Nassau and Suffolk counties in Long Island. The dates of the ED visits were grouped into 4 periods: (1) pre-Sandy, October 1–28; (2) during Sandy, October 29; (3) post-Sandy I, October 30 to November 1; and (4) post-Sandy II, November 2–30.ResultsA total of 126,337 ED visits were recorded among 23 EDs. A significant drop in volume was observed on October 29; 399 more ED visits for physical health diagnoses were identified in the post-Sandy I period than in the pre-Sandy period. “Diseases of the respiratory system” was the only diagnosis group that showed a positive trend in the post-Sandy I period compared with the pre-Sandy period (increase of 4%). No significant changes in mental health visits were observed after Sandy landfall.ConclusionsThis analysis suggests that the critical temporal window during which ED resources should be increased is in the immediate aftermath of a hurricane.

AbstractBy using strontium isotopic ratios of dental enamel from molars, we were able to reconstruct the migration context for three individuals of a Columbian mammoth population (Mammuthus columbi) around Laguna de las Cruces, San Luis Potosí, central México. A three-step leaching procedure was applied to eliminate secondary Sr contributions in the molar enamel. One of the studied individuals showed87Sr/86Sr ratios similar to those obtained from soils and plants from Laguna de las Cruces and was identified as local, whereas the other two mammoths had different molar87Sr/86Sr values, indicative of migration and mobility contexts.
