Parenteral Nutrition Electrolyte Abnormalities and Associated Factors Before and After Nutrition Support Team Initiation
Authors: Braun Katie , Utech Anne , Velez Maria Eugenia , Walker Renee 
Published: October 2016

AbstractBackground: Studied since the 1940s, refeeding syndrome still has no universal definition, thus making comparison of studies difficult. Negative outcomes (eg, metabolic abnormalities) may occur with the use of specialized nutrition, such as parenteral nutrition (PN). Less than half of medical institutions have a nutrition support team (NST) managing PN. Interdisciplinary team management of PN may reduce negative outcomes of PN. The objective of this study was to show the value of the NST by measuring differences in PN variables, especially electrolyte abnormalities (EAs), before and after NST initiation at a large medical center and to identify factors associated with EAs among adult subjects receiving PN. Materials and Methods: During this retrospective study, computerized medical charts (N = 735) from 2007–2010 were reviewed for electrolyte changes (particularly potassium, magnesium, and phosphorus) the first 3 days following PN initiation in hospitalized adults. Changes in EAs with other variables were compared before and after NST implementation. Equivalent samples sizes were collected to better evaluate the impact of the team. Results: Following the implementation of the NST, fewer EAs were seen in PN patients (53%; χ2 = 10.906, P = .004); significantly less potassium, phosphorus, and magnesium intravenous piggyback supplementation (88.8% vs 94%; χ2 = 5.05, P = .026) was used; and mortality within 30 days of PN cessation was significantly less (12.7% vs 10.6%, P = .012). Conclusion: Our study complements existing research, finding that an NST was associated with a decreased occurrence of EAs and mortality in the hospitalized adult receiving PN.

Published: October 2016

Background: The indications for hip preservation surgery have expanded to include treatment of hip pathology in older adults. While several studies have examined the efficacy of hip arthroscopy in the setting of osteoarthritis, there has been no review of outcomes in older adults. Purpose: To review the outcomes of hip arthroscopy in older adults and identify factors associated with treatment failures. Study Design: Systematic review. Methods: PubMed, EMBASE, and the Cochrane Library were searched through March 2016 for studies reporting outcomes of primary hip arthroscopy in patients older than 40 years. Inclusion in the review was based on age, patient-reported outcome (PRO) measures, and duration of follow-up. Two authors screened the results and extracted data for use in this review. Standardized mean difference was calculated to estimate effect size for PRO scores within studies. Results: Eight studies with 401 total patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) or labral tears were included in this review. Seven of the 8 studies reported favorable PRO scores and significant postoperative improvement with moderate to large effect size. The included studies demonstrated a trend toward higher effect sizes with an increasing percentage of labral repair compared to isolated labral debridement. The complication rate was comparable to that of previous reports involving younger patients; however, the overall reoperation rate was 20.8%. Conversion to hip arthroplasty ranged from 0% to 30%, with an overall conversion rate of 18.5% at a mean time of 17.5 months following arthroscopy. The most common risk factors for conversion to arthroplasty were low preoperative PRO scores and advanced arthritis. Conclusion: Hip arthroscopy appears to be a safe and efficacious treatment for labral tears and FAI in older patients who do not have significant underlying degenerative changes. However, in this population, there is a significant proportion of patients who eventually require hip arthroplasty. Outcomes may be affected by type of treatment (ie, labral debridement vs repair). Additional high-quality studies are needed to understand how these factors affect outcomes.

Authors: Yang Yong , Diez-Roux Ana V. 
Published: October 2016

Purpose: Studies on how the interaction of psychological and environmental characteristics influences walking are limited, and the results are inconsistent. Our aim is to examine how the attitude toward walking and neighborhood environments interacts to influence walking. Design: Cross-sectional phone and mail survey. Setting: Participants randomly sampled from 6 study sites including Los Angeles, Chicago, Baltimore, Minneapolis, Manhattan, and Bronx Counties in New York City, and Forsyth and Davidson Counties in North Carolina. Participants: The final sample consisted of 2621 persons from 2011 to 2012. Measures: Total minutes of walking for travel or leisure, attitude toward walking, and perceptions of the neighborhood environments were self-reported. Street Smart (SS) Walk Score (a measure of walkability derived from a variety of geographic data) was obtained for each residential location. Analysis: Linear regression models adjusting for age, gender, race/ethnicity, education, and income. Results: Attitude toward walking was positively associated with walking for both purposes. Walking for travel was significantly associated with SS Walk Score, whereas walking for leisure was not. The SS Walk Score and selected perceived environment characteristics were associated with walking in people with a very positive attitude toward walking but were not associated with walking in people with a less positive attitude. Conclusion: Attitudes toward walking and neighborhood environments interact to affect walking behavior.

Published: October 2016

Background and Purpose: The safety and efficacy of intravenous tissue plasminogen activator (IV tPA) following acute ischemic stroke (AIS) is dependent on its timely administration. In 2014, our Comprehensive Stroke Center designed and implemented a computed tomography-Direct protocol to streamline the evaluation process of suspected patients with AIS, with the aim of reducing door-to-needle (DTN) times. The objectives of our study were to describe the protocol development and implementation process, and to compare DTN times and symptomatic intracranial hemorrhage (sICH) rates before and after protocol implementation. Methods: Data were prospectively collected for patients with AIS receiving IV tPA between January 1, 2010, and May 31, 2015. The DTN times, examined as median times and time treatment windows, and sICH rates were compared pre- and postimplementation. Results: Two hundred ninety-five patients were included in the study. After protocol implementation, median DTN times were significantly reduced (38 vs 28 minutes; P < .001). The distribution of patients treated in the three time treatment windows described below changed significantly, with an increase in patients with DTN times of 30 minutes or less, and a decrease in patients with DTN times 31 to 60 minutes and over 60 minutes ( P < .001). There were two cases of sICH prior to implementation and one sICH case postimplementation. Conclusions: The implementation of a protocol that streamlined the processing of suspected patients with AIS significantly reduced DTN time without negatively impacting patient safety.
Halloysite nanotubes with fluorinated cavity: an innovative consolidant for paper treatment
Authors: Cavallaro Giuseppe , Lazzara Giuseppe , Milioto Stefana , Parisi Filippo 
Published: October 2016

AbstractHybrid material based on halloysite nanotubes (HNTs) and sodium perfluorooctanoate (NaPF8) was used as a consolidant for paper treatment. The consolidation efficiency was determined by thermogravimetry as well as by paper grammage determination. Morphological analysis of the treated paper was performed by means of scanning electron microscopy while the effect of modified HNTs on the thermal behaviour of the cellulose fibres was investigated by differential scanning calorimetry which determined the combustion enthalpy of the paper.Water contact angle measurements were performed to study the paper wettability. The physico-chemical properties investigated (mesoscopic structure, thermal stability and wettability) of the treated paper were correlated successfully with the consolidation loading and, consequently, to the affinity between the fluorinated modified HNTs and the fibrous cellulose structure. This study proposes a new green protocol for paper consolidation based on natural tubular nanoparticles with a flame retardant effect.
Polysaccharide-halloysite nanotube composites for biomedical applications: a review

Published: October 2016

AbstractAs a unique tubular nanoclay, halloysite nanotubes (HNTs) have recently attracted significant research attention. The HNTs have outer diameters of ∼50 nm, inner lumens of ∼20 nm and are 200–1000 nm long. They are biocompatible nanomaterials and widely available in nature, which makes them good candidates for application in biomedicine. Compared with other types of nanoparticles such as polymer nanoparticles and carbon nanotubes, the drawbacks associated with HNTs include brittleness, difficulty with fabrication, low fracture strength, high density and inadequate biocompatibility. Preparation of polysaccharide-HNT composites offer a means to overcome these shortcomings. Halloysite nanotubes can be incorporated easily into polysaccharides via solution mixing, such as with chitosan (CS), sodium alginate, cellulose, pectin and amylose, for forming composite films, porous scaffolds or hydrogels. The interfacial interactions, such as electrostatic attraction and hydrogen bonding, between HNTs and the polysaccharides are critical for improvement of the properties. Morphology results show that HNTs are dispersed uniformly in the composites. The mechanical strength and Young's modulus of the composites in both the dry and wet states are enhanced by HNTs and the HNTs can also increase the storage modulus, glass-transition temperature and thermal stability of the composites. Cytocompatibility results demonstrate that the polysaccharide-HNT composites have low cytotoxicity even for HNT loading >80%. Therefore, the polysaccharide-HNT composites show great potential for biomedical applications, e.g. as tissue engineering scaffold materials, wound-dressing materials, drug-delivery carriers, and cell-isolation surfaces.

Abstract
Background
Overweight is a global issue of epidemic proportions, and its negative influence on individual health is clear. However, the relation between environment and overweight is not thoroughly clear, especially concerning to the perceived environment and the physical and social aspects. Therefore, this study aimed to analyze potential associations between the perceived environment and overweight in adults and elderly in a medium-sized city.

Methods
A cross-sectional population-based study was conducted with 808 adult and elderly individuals. Overweight was defined as body mass index ≥25 kg/m2 based on the World Health Organization criteria. The Neighborhood Environment Walkability Scale was used evaluating the perceived environment. Poisson regression was performed evaluating the relationships between the perceived environment and overweight.

Results
The frequency of overweight was 50.4 %. Adjusted models showed association between overweight and the variable of surrounding neighborhood as follows: “1- to 3-story apartments or condos” (most category; PR = 0.30; CI 0.12–0.76) and “4- to 6-story apartments or condos” (all categories) (PR ranged 0.40 to 0.46; p < 0.05), and also, “land-use mix-diversity” was associated with overweight in this population (PR 0.81; CI 0.66–0.99).

Conclusions
In addition to individual characteristics, the environmental aspects are relevant to the occurrence of overweight in this population. Population-based studies using primary data on overweight remain scarce in Brazil. Finally, this study contributes to improve the understanding of the complex relationship between perceived environment and overweight, and we believe that our findings provide further justification for the development of future interventions and health promotion strategies.
Synthesis and Reactivity of Functionalized Silicon(II) Compounds: Iminosilylene, Phosphinosilylene, Hydrosilylene, and Related Compounds
Authors: Bag Prasenjit , Ahmad Syed Usman , Inoue Shigeyoshi 
Published: October 2016

AbstractRecent decades have witnessed the isolation of a large number of stable silicon(II) compounds along with their applications toward small molecule activation and as versatile ligand systems for transition-metal complexes. The employment of donor stabilization techniques has proven to be an effective mean for stabilization of such silicon(II) systems that is consequently helpful in further reactivity investigations. In this context, an overview of the study of donor-stabilized silicon(II) compounds bearing unique functionalities that have recently been investigated in our research group is presented. By the use of amidinato ligand or N-heterocyclic carbene (NHC), the access to heteroatom-functionalized silicon(II) compounds has been achieved and exploration of further reactivity has led to the isolation of additional novel silicon(II) species. Applications of these silicon(II) compounds as ligands towards transition-metal complexes and in activation of organic and inorganic small molecules are also described.
Corporate Governance and Costs of Equity: Theory and Evidence
Authors: Li Di , Li Erica X. N. 
Published: October 2016

We propose and test an alternative explanation for the existence of the positive governance–return relation in the 1990s and its disappearance in the 2000s: The governance–return relation is positive under good states of the economy and negative under bad states. Corporate governance mitigates investment distortions so that firms with strong governance have more valuable investment options during booms and more valuable divestiture options during busts than the ones with weak governance. Because investment options are riskier and divestiture options are less risky than assets in place, the expected returns of strongly governed firms are higher during booms but lower during busts than the weakly governed ones. Empirical evidence is consistent with our hypothesis. This paper was accepted by Neng Wang, finance.

Published: October 2016

Abstract
This study investigates the effect of different activating flux such as V2O5, TiO2, MoO3, Cr2O3, and Al2O3 on A-TIG welding process of Incoloy 800H. The influence of the flux on the depth of penetration and on mechanical and metallurgical characteristics of the weld were studied and compared with autogeneous TIG welds which were welded with the same process parameters and conditions. The use of TiO2 flux gave full depth of penetration and the use of V2O5, Cr2O3 flux gave increased penetration as compared to autogeneous TIG welds while the use of Al2O3 and MoO3 led to the detoriation of the effect.

Croatia has one of its weakest economies in European Union. The most powerful engine driving a nation’s economy is its businesses. But Croatian business is not faring well. The Croatian government is hoping tourism will help revive the economy. This is a realistic hope but one that will be realized only through concerted action by business, government, and the education sector.
The Soft Rock Socketed Monopile with Creep Effects – A Reliability Approach based on Wavelet Neural Networks
Authors: Kozubal Janusz , Tomanovic Zvonko , Zivaljevic Slobodan 
Published: October 2016

AbstractIn the present study the numerical model of the pile embedded in marl described by a time dependent model, based on laboratory tests, is proposed. The solutions complement the state of knowledge of the monopile loaded by horizontal force in its head with respect to its random variability values in time function. The investigated reliability problem is defined by the union of failure events defined by the excessive horizontal maximal displacement of the pile head in each periods of loads. Abaqus has been used for modeling of the presented task with a two layered viscoplastic model for marl. The mechanical parameters for both parts of model: plastic and rheological were calibrated based on the creep laboratory test results. The important aspect of the problem is reliability analysis of a monopile in complex environment under random sequences of loads which help understanding the role of viscosity in nature of rock basis constructions. Due to the lack of analytical solutions the computations were done by the method of response surface in conjunction with wavelet neural network as a method recommended for time sequences process and description of nonlinear phenomenon.
The Effectiveness of the Methane Drainage of Rock-Mass with a U Ventilation System
Authors: Szlązak Nikodem , Swolkień Justyna 
Published: October 2016

Abstract
Methane drainage is used in Polish coal mines in order to reduce mine methane emission as well as to keep methane concentration in mine workings at safe levels.
The article describes the method of methane drainage used in longwall D-2 in seam 410. In Poland, coal seams are frequently mined under difficult geological conditions in the roof and in the presence of very high methane hazard. In such situations, mines usually use a system with roof caving and a U ventilation system, which means that methane is drawn off from a tail entry behind the longwall front. In this system, boreholes are drilled from a tailgate and methane is drawn off from behind longwall face.
The article shows the influence of a specific ventilation system on the drainage efficiency at longwall D-2 in seam 410. At this longwall, measurements of methane emission and the efficiency of methane capture were conducted. They consisted in gauging methane concentration, air velocity, absolute air pressure and the amount of methane captured by the drainage system. Experimental data were used to estimate the variations in absolute methane-bearing capacity and ventilation methane, and – most importantly – to gauge the efficiency of methane drainage.
A Simulated Annealing based Optimization Algorithm for Automatic Variogram Model Fitting
Authors: Soltani-Mohammadi Saeed , Safa Mohammad 
Published: October 2016

AbstractFitting a theoretical model to an experimental variogram is an important issue in geostatistical studies because if the variogram model parameters are tainted with uncertainty, the latter will spread in the results of estimations and simulations. Although the most popular fitting method is fitting by eye, in some cases use is made of the automatic fitting method on the basis of putting together the geostatistical principles and optimization techniques to: 1) provide a basic model to improve fitting by eye, 2) fit a model to a large number of experimental variograms in a short time, and 3) incorporate the variogram related uncertainty in the model fitting. Effort has been made in this paper to improve the quality of the fitted model by improving the popular objective function (weighted least squares) in the automatic fitting. Also, since the variogram model function (£) and number of structures (m) too affect the model quality, a program has been provided in the MATLAB software that can present optimum nested variogram models using the simulated annealing method. Finally, to select the most desirable model from among the single/multi-structured fitted models, use has been made of the cross-validation method, and the best model has been introduced to the user as the output. In order to check the capability of the proposed objective function and the procedure, 3 case studies have been presented.
The Age of Consent and the Reduction of the age of Consent in Church and Civil Marriages and their Interaction
Authors: Grigienė Jurgita , Čerka Paulius , Perkumienė Dalia 
Published: October 2016

AbstractIn order for marriage to be valid, material conditions for marriage should be fulfilled. The form of marriage and material conditions for marriage have changed over the ages. Today marriage can be formed both by a civil and church order. The recognition of church marriage also differs from state to state. Some countries have chosen not to recognise church marriage and some countries have chosen to recognise church marriage. Church marriage is recognised by the state of Lithuania. However, only church marriages which correspond to requirements of material marriage conditions can be included in the public register. Marital age both in church and civil marriage is the same - 18 years. Under special circumstances the age of consent can be reduced. There exist different conditions for the reduction of marital age in church and civil marriage procedure. In church marriage, the bishop must give permission to reduce marital age, and in civil marriage only the court can reduce marital age. The authors of the article recommend obtaining court permission to reduce marital age even though performing the church marriage, because, otherwise, the church marriage will not be included into the public register by the state. As marital age and reduction of marital age differ from country to country, the authors also analyse when marriages concluded abroad shall be recognized if they do not satisfy the requirement of age.
