Authors: Fernández Enrique , Padilla Paula , Monardes Héctor , Díaz Carlos
Published: June 2017

La gerontología es la ciencia que trata de la vejez y de los fenómenos psicológicos, sociológicos y económicos que la caracterizan. Desde la vertiente sociológica se acuñó el término viejismo, que hace alusión al proceso de elaboración de estereotipos y discriminación sistemática contra las personas debido a que son mayores. Diversas proyecciones demográficas indican un crecimiento constante de la población adulta mayor, por lo que el viejismo adquiere entonces una gran importancia. Objetivos: Determinar las actitudes hacia los adultos mayores que presentan los estudiantes de Odontología de la Universidad San Sebastián, sede Santiago. Material y Métodos: Se aplicó la escala de actitudes hacia el adulto mayor de Kogan (KAOP), validada en español, en 158 alumnos de tres cohortes distintas de la carrera. Resultados: Los estudiantes que formaron parte de este estudio reportaron tener en promedio, una actitud negativa hacia el adulto mayor (valor KAOP 131,73). No hay diferencias estadísticamente significativas por género ni por año académico en los datos observados. Conclusiones: La actitud hacia el adulto mayor observada entre los estudiantes de Odontología de la Universidad San Sebastián, sede Santiago, es negativa, sin encontrarse diferencias por género ni por nivel. Se requieren más estudios en el tema, para dilucidar las posibles causas.

Contribution of Gandhian Thought to Corporate Responsibility
Authors: Pulla Venkat Rao , Nayak Vinod , Walke Keshav
Published: June 2017

Mahatma Gandhiji transformed contemporary capitalists amidst the criticism from leftist quarters that he was working for a compromise in the interests of the Indian bourgeoisie. The purpose of this paper is to present a forerunner of today’s conversations in the world about corporate social responsibility (CSR). Gandhiji not only befriended a number of businesspersons but also advised them to consider their role as a steward of their wealth and businesses that they held. We intend to substantiate his pious intentions derived from his understanding of Bhagavad Gita, which suggested to him that one could enjoy one’s acquired wealth by renouncing it. Persuaded by such moral disposition, Gandhiji argued that it is the surest method to evolve a new order of life of universal benefit of all people in the society as opposed to the order in which most of us live for ourselves without regard to what happens to our neighbour. The paper is based on archival materials representing his conceptualisation and acceptance of trusteeship and the collaborations of the capitalists that lived in his times.

Special Issue on the 2016 Kumamoto Earthquakes
Authors: Hayashi Haruo
Published: June 2017

At 9:26 pm on April 14, 2016, a magnitude 6.5 earthquake struck directly beneath Kumamoto prefecture, Japan, producing a seismic intensity level (JMA) of 7 in Mashiki Town. Although the earthquake damage forecasting system in operation at the time predicted that this earthquake would cause no damage, it resulted in extensive human casualties and property damage centered in Mashiki Town. Past midnight on April 16, 28 hours after the first shock, the second and main shock hit, which recorded magnitude 7.3 and was the strongest recorded urban earthquake in Japan since 1995. The hypocenter extended from Kumamoto prefecture to Oita prefecture, cutting across the island of Kyushu. Mount Aso also saw increased volcanic activities which led to several landslides. This resulted in the collapse of the Great Aso Bridge, an important transportation point, causing the loss of human lives as well as obstruction of traffic for an extended period. Much confusion arose in the process of implementing measures in response to the earthquakes, which produced damage in urban areas as well as hilly and mountainous regions, raising many issues and prompting several new approaches. Researchers in many fields have conducted various activities at the disaster sites in the one-year period following the earthquakes, and produced significant findings in many areas. In order to make these results available to the wider global community, JDR is releasing a special issue on the 2016 Kumamoto Earthquakes with excellent papers and reports to mark their one-year anniversary. While the submitted papers to this special issue went through our regular peer review process, no publication charge was imposed so as to encourage as many submissions as possible.

It is our hope that this special issue will contribute to throwing light on the 2016 Kumamoto Earthquakes in its entirety.

Published: June 2017

To study the effect of to low-intensity low frequency pulsed ultrasound (LILFPUS) on the surface wettability of titanium dental implants, an experimental medical-technical model was developed, consisting of an ultrasonic device, a fixed-mounted digital photo/video camera and a laboratory stand with a smooth vertical feed, in which an ultrasound nozzle with an experimental dental implant and fastener with a control implant were fixed. As a wetting agent, 0.9 % sterile physiological sodium chloride solution was used in a petri dish tinted with brilliant green. Using the components of the model, it was possible to immerse the control and experimental dental implants, fixed on a laboratory stand, equally and uniformly at the same depth. The results of the studies showed that under the influence of ultrasound, the wetting of the surface of all the test samples was 100 %, and the wetting of the control samples was not observed.

Application of orthogonal neighborhood preserving projections and two dimensional hidden Markov model for the degradation evaluation of rolling elements bearings
Authors: Zhang Yongxiang , Xiao Yujie , Zhang Shuai , Wang Shengjie
Published: June 2017

An effective degradation indicator created from the general features is still a hotspot for the condition monitoring of bearing. To cover the shortage of the general features based indicator, some new indicators are built using multiple general features extracted from the original vibration signal without considering the internal relevancy among the features. To address that problem, a new indicator is proposed using the Orthogonal Neighborhood Preserving Projections (ONPP) and 2-Dimensional Hidden Markov Model (2-D HMM). With the ability of keeping the local structure of data set, Orthogonal Neighborhood Preserving Projections is used to obtain the low dimensional features with the main information remained. Unlike 1-Dimensional data-processing algorithm that commonly converts the multiple features into a vector to deal with the high-dimensional data with the integral property of the multiple features considered only, 2-Dimensional Hidden Markov Model not only take the relevance between the individuals of fault features into consideration but also capture the global characteristics of the multiple features. Then a likelihood probability based health assessment indication can be constructed by combing 2-D HMM with the data pre-processed by ONPP. The experiment results indicate that the proposed indicator show great abilities to make degradation performance of the bearing and is sensitive to incipient defects.
A piezoelectric motor driven by a single-phase signal
Authors: Li Chong , Lu Cun-Yue , Ma Yi-Xin
Published: June 2017

This paper aims to present a proof-of-concept for a novel piezoelectric motor using a single-phase driving signal. The stator is constructed by bonding a Terfenol-D plate and a piezoelectric ceramic (PZT) plate onto the outer surface of a metal base. The PZT plate based on d31 effect is used to simultaneously excite two in-plane bending modes of the stator. Similarly, the Terfenol-D plate can also be used to excite the two bending modes. By superposition of the two bending modes, elliptical motions of the stator surface points are generated. The working modes and vibration characteristics of the motor are analyzed by finite element analysis software. The resonance frequencies of the two bending modes are tuned to be close by additional mass. The dimensions of the stator are optimized to maximize the output displacement. To confirm the feasibility of the proposed design, a prototype motor is fabricated and tested. The size of the prototype motor is about 11.2×10.7×28.0 mm3. The tested resonance frequencies of the two bending modes are 16.0820 kHz and 16.3476 kHz respectively. The maximum no-load speed is 85 rpm. The applied driving voltage is 100 Vo-p (peak voltage) at a frequency of 16.34 kHz.
Numerical optimization of sound pressure responses for the dash panel based on automatically matched layer and genetic algorithm
Authors: Zhang Xin Zhe , Zhang Guo Jie
Published: June 2017

The sound insulation performance of the dash panel has a direct influence on the level of sound absorption of the whole vehicle. Therefore, it is necessary to adopt proper optimization strategies to optimize the dash panel and interior sound pressure response. Firstly, damping loss factor was imported into the dash panel and the coupling model of interior acoustic cavity to compute the sound pressure response of the driver. Sound pressure response had multiple peak noises in the analyzed frequency band. With the increase of the analyzed frequency, Contours for the noise of interior acoustic cavity became increasingly dispersed. Secondly, reverberation chambers on both sides were coupled with the dash panel respectively to establish AML model. In this way, the computational transmission loss would be more consistent with the actual situation. AML method can directly obtain transmission loss without extracting the transmission sound power to compute transmission loss through relevant formulas. In reported papers, there are big differences between simulation and experiment in the low frequency because it is difficult to simulate the real boundary conditions. The computational results of this paper were more consistent with experimental results in the whole frequency band, which indicated that it was more effective to use AML method to compute the transmission loss of the dash panel. Then, a sound package was applied to the dash panel to conduct parametric analysis. Results showed that the thickness of the sound-absorption layer could effectively improve transmission loss over 250 Hz. When the thickness of the sound-absorption layer was 15 mm, transmission loss was relatively optimal. In addition, the thickness of the air layer had little influence on transmission loss. Finally, genetic algorithm was also used to optimize the parameters of sound package of the dash panel. Results showed that the optimized dash panel had a higher average transmission loss and total mass, and the average sound pressure response of the driver also decreased. Additionally, the transmission loss and sound pressure response of the driver optimized by genetic algorithm at each frequency point were improved in the analyzed frequency band to obtain a low-noise and lightweight dash panel.

Authors: Wu Hongfang , Jia Tianyu , Li Na , Wu Jian , Yan Lei
Published: June 2017

A sliding mode control algorithm based on proportional switching function was developed to make the lower limb exoskeleton more fit the human walking gait trajectory. It could improve the comfort of the exoskeleton wearer and enhance the reliability of the system. The three-dimensional mechanical model of the exoskeleton built using software SolidWorks was introduced to ADAMS and then the model parameters were set. The model was combined with the software MATLAB so that the human-machine cooperation control algorithm for lower limb exoskeleton based on ADAMS and Simulink co-simulation was developed. The simulation result was compared with the desired trajectory and the trajectory under PID control. The research discovered that the ability of trajectory tracking under the sliding mode control was much better than that under PID control. It provided an important theoretical basis for the research on human-machine cooperation control algorithm.
Improving the weak feature extraction by adaptive stochastic resonance in cascaded piecewise-linear system and its application in bearing fault detection
Authors: Liu Houguang , Han Shuai , Yang Jianhua , Liu Songyong
Published: June 2017

In mechanical engineering field, early fault features are extremely weak and submerged in heavy noise, and the weak feature extraction is quite challenging. In this work, we apply the adaptive stochastic resonance in cascaded piecewise-linear system to extract the weak features. The adaptive stochastic resonance is realized by the quantum particle swarm algorithm. By optimizing system parameters, the efficiency of the feature extraction is improved greatly. As a result, the weak features can be easily extracted eventually. The effectiveness and the high-performance of the proposed method are verified by the numerical simulation and experimental data of rolling element bearings. The bearing fault under different motor loads is detected effectively, consequently confirming the robustness of the proposed method.
Development of online detection system for natural frequency of brake discs based on the improved least squares complex frequency domain method
Authors: Chu Zhigang , Huang Di , Wang Jiang , Yang Yang
Published: June 2017

This paper firstly introduced the theory and implementation of the least squares complex frequency domain (LSCF) method based on the truncated singular value decomposition (SVD) for noise reduction. The simulation results of signals with different signal noise ratios (SNR) show that this algorithm is stable and has excellent capacity of resisting noise disturbance. On this basis, an online detection system for natural frequency of brake discs is developed. This system takes the LAN-XI date acquisition module and LABSHOP software of B&K as platform and uses Visual Basic (VB) and MATLAB mixed programming technique for its secondary development. The LSCF method based on the truncated SVD is applied for curve fitting and modal parameter extracting. The qualified criterion is that the stably appearing natural frequencies are in the tolerance ranges. The practical application shows that this system intuitively and accurately displays the detection results and performs stably and efficiently.
Investigation the influence of shear distortion, rotary inertia and longitudinal vibration on the power flow transmission of a finite L-shaped beam
Authors: Li Jia-Xing , Zhu Xue-Zhi , Chen Zhao-Bo , Jiao Ying-Hou
Published: June 2017

The dynamics response and power flow propagation in the L-shaped beam with finite dimension were investigated. A L-shaped beam dynamic model was established on the basis of Timoshenko beam theory (TBT) and Euler-Bernoulli beam theory (EBT). The analytical solution was obtained and the beam flexural and longitudinal motion was described by using the traveling wave approach. The effects of shear distortion and rotary inertia on the total power flow and its components were examined. Results shown that the structure resonant frequencies are obviously affected by the shear distortion and rotary inertia, especially for the medium and high frequency ranges. The power flow amplitude is obviously increased on the premise of considering the longitudinal vibration. Consequently, the longitudinal vibration should be considered for the power flow and its components in the L-shaped beam.
Dynamic behaviour of a novel transition wedge composed by prefabricated reinforced concrete slabs
Authors: Labrado-Palomo M. , Morales-Ivorra S. , Ribes-Llario F. , Real-Herráiz J. I.
Published: June 2017

Abrupt variations of track stiffness in transitions from conventional to slab track, e.g., over bridges and tunnels, usually lead to passenger discomfort, vehicle and track damage and even safety issues. Therefore, to minimize this negative effect, it is very convenient to smooth the stiffness changes in such transitions; and wedges arise as a very effective technique. Although granular wedges are commonly suggested by railroad managers as a solution, this typology presents some disadvantages, e.g., high construction time and costs, that should be addressed. In this paper, a new solution based on prefabricated, reinforced concrete slabs is presented and its dynamical performance is assessed by means of a 3D FEM model. Results indicate that track vibrations both on the rail and over a sleeper are considerably reduced when the new slab-based wedge is considered instead of a traditional granular wedge.
Epigenetic Regulation of EMT in Non-Small Cell Lung Cancer
Authors: O’Leary Karen , Shia Alice , Schmid Peter
Published: June 2017

Lung cancer remains the most diagnosed cancer in the world, with a high mortality rate
and fewer therapeutic options. The most common lung cancer is non-small cell, consisting of adenocarcinoma,
squamous cell carcinoma and large cell lung carcinoma. As per all solid tumours, the
changes that occur for the initiation and metastasis of lung cancer can be described using the EMT
(epithelial mesenchymal transition). Cells progressing through EMT lose their epithelial cell characteristics,
expressing more mesenchymal markers and are phenotypically different. The transition can
be controlled by changes in various pathways, such as TGF-β, PI3K, MAPK, Hedgehog and Wnt.
The changes in those pathways can be controlled epigenetically, via DNA methylation, histone
modifications or changes in small/non-coding RNA. We will describe the epigenetic changes that
occur in these pathways and how we can consider novel methods to generate a synthetic lethality
target in an epigenetically regulated pathway in EMT.

C-Abl Inhibition; A Novel Therapeutic Target for Parkinson's Disease
Authors: Abushouk Abdelrahman Ibrahim , Negida Ahmed , Elshenawy Rasha Abdelsalam , Zein Hossam , Hammad Ali M. , Menshawy Ahmed , Mohamed Wael M.Y.
Published: June 2017

Parkinson's disease (PD) is the most prevalent movement disorder in the world. The major
pathological hallmarks of PD are death of dopaminergic neurons and the formation of Lewy bodies.
At the moment, there is no cure for PD; current treatments are symptomatic. Investigators are searching
for neuroprotective agents and disease modifying strategies to slow the progress of neurodegeneration.
However, due to lack of data about the main pathological sequence of PD, many drug targets
failed to provide neuroprotective effects in human trials. Recent evidence suggests the involvement of
C-Abelson (c-Abl) tyrosine kinase enzyme in the pathogenesis of PD. Through parkin inactivation,
alpha synuclein aggregation, and impaired autophagy of toxic elements. Experimental studies showed
that (1) c-Abl activation is involved in neurodegeneration and (2) c-Abl inhibition shows neuroprotective
effects and prevents dopaminergic neuronal' death. Current evidence from experimental studies
and the first in-human trial shows that c-Abl inhibition holds the promise for neuroprotection against
PD and therefore, justifies the movement towards larger clinical trials. In this review article, we discussed
the role of c-Abl in PD pathogenesis and the findings of preclinical experiments and the first
in-human trial. In addition, based on lessons from the last decade and current preclinical evidence, we
provide recommendations for future research in this area.

El discurso de las competencias ha permeado gradualmente las instituciones de educación superior; aspectos como el currículo, la evaluación y los perfiles profesionales han sido reestructurados bajo este enfoque. No obstante, su visión sesgada y polisémica ha tenido muy poco impacto en el contexto y la cultura de cada comunidad académica. Para dar cuenta de esta problemática, metodológicamente se recurre a la revisión documental y el levantamiento de fuentes indexadas en diversos textos, a través del uso de la teoría fundamentada y los métodos de comparación constante y codificación abierta. Consecuentemente, se muestra, a manera de resultado, un posicionamiento reflexivo en torno a la importancia del currículo como oportunidad de cambio formativo y su incidencia en los perfiles profesionales para contextualizar la educación superior, incluyendo marcos de análisis basados en la emancipación social y el estudio de género en el diseño del perfil profesional.
Lower-Level Processing Skills in English-as-a-Second-Language Reading Comprehension: Possible Influence of First Language Orthography
Authors: Jiang Xiangying
Published: June 2017

Cross-linguistic studies on second language (L2) reading reveal that component skills of reading such as word recognition, phonemic decoding, spelling, and oral text reading are prone to the influence of first language (L1) orthography but few empirical studies have examined the possible influence of L1 orthography on these skills. This study investigates how adult ESL learners of two different L1 backgrounds (Spanish and Chinese) compare in their performances on word recognition efficiency, phonemic decoding efficiency, spelling, and oral text reading fluency and how these skills are related to their overall ability in reading comprehension. The differences in the learners’ performances on the component skills and the variations in the role of these skills in ESL reading comprehension indicated possible influence of the orthographic features of learners’ first language.

Published: June 2017

This article aims to describe how early Islamic civilization was formed, which later became the foundation for later Islamic civilization. This paper with a historical approach tries to explain about the intellectual communication between the early Islamic civilization with the Greek civilization. This paper found that communication between Islamic civilization with Greek civilization started from the interaction process of Islamic scholars with Greek works through the process of massive translation during the Caliph Al-Mamun. The results of this translation have implications for the philosophy and theology of Islam proposed by early Islamic thinkers and philosophers. Although the philosophical and theological thinking they constructed was a Hellenistic, they blended on the principles of Islamic teachings, making it a distinctive philosophy and theology of Islam. From this was born Islamic civilization built on the foundation of faith and science in a balanced way, which is different from the Greek civilization is not based on faith. Intellectual communication between Islamic civilization with this Greek civilization which later gave birth to the European Renaissance.
My Child Is Islet Autoantibody Positive: Impact on Parental Anxiety
Authors: Johnson Suzanne Bennett , Lynch Kristian F. , Roth Roswith , Schatz Desmond ,   the TEDDY Study Group
Published: June 2017

OBJECTIVE

To assess parent anxiety in response to genetic and islet autoantibody (IA) testing in children at increased genetic risk for type 1 diabetes followed from birth in The Environmental Determinants of Diabetes in the Young (TEDDY) study.

RESEARCH DESIGN AND METHODS

Parent anxiety about TEDDY children’s risk was assessed with the State Anxiety Inventory (SAI). Parents completed the SAI when the child was 3, 6, and 15 months old and annually thereafter. Children were tested for IA every 3 months for 4 years and every 6 months thereafter. Parent SAI scores of 6,799 children followed with IA testing for at least 1 and up to 6 years were examined.

RESULTS

At study inception, parents showed high levels of anxiety in response to their child’s increased genetic type 1 diabetes risk; mothers were more anxious than fathers, and parents with diabetes in the family were more anxious than parents with no family history. In response to repeated IA-negative (IA−) test results, parent anxiety declined to normal levels. Anxiety increased in parents faced with an IA-positive (IA+) test result. Parents faced with two or more types of IA+ test results showed particularly high levels of anxiety (all P < 0.001).

CONCLUSIONS

Infant genetic screening for type 1 diabetes raises parent anxiety when the child is at increased risk, but anxiety dissipates over time in cases of repeated IA− results. IA+ results heighten parent anxiety, and parents faced with two or more types of IA+ results may experience considerable anxiety for longer periods.

Problems of study of conversions to Islam in the Sufi communities of the West: socio-cultural context, institutions, charisma
Authors: Yarosh Oleg
Published: June 2017

Present paper examines the processes of native Europeans conversion to Islam in relation to the Sufi communities in the West. It deals with theoretical aspects of the study of Western Sufi communities, the conceptualization of religious conversion and its motives, as well as collective factors and individual trajectories of conversion on the basis of own field research in the Sufi communities in Western Europe and materials presented in the relevant studies. The paper shows that conversion to Islam through Sufi communities is characterized by the transition from religious individualism to collectively shared normativity, while the charisma of the shaykh largely determines the collective identity of the community and affects the life trajectories of its members.

In this study, an experiment of hemp crops was conducted between in four different regions of the country, and concerned
three varieties Santhica 27, Epsilon 68 and Futura 75. The tests were conducted in areas with geographical, climatic and
soil characteristics different than European cultures, that’s why it was necessary to verify the behavior of these plants by
controlling their Δ-9-THC content. Sampling, drying and Δ-9-THC evaluation in these crops were performed according
to procedure B of European Regulation, and using a simplified method based on the determination of the ratio α = Δ-9-
THC/CBD. The best dry matter yields, plant height and density are obtained with the variety Futura 75 in the four sites,
followed by Epsilon 68 and Santhica 27. The average contents of these crops in Δ-9-THC were ranged from 0.013% to
0.027% for the variety Epsilon 68, between 0.023% and 0.035% for the variety Futura 75. Analysis of this latter variety
by GC / MS SIM mode and LC/MS/MS allowed the identification of traces of Δ-9-THC. In the other hand, the ratio α has
been evaluated to 0.042 and 0.047 respectively for Epsilon 68 and Futura 75 varieties which is similar to those usually
obtained for hemp fiber crops and stays much lower than 0.2. The Principal Component Analysis confirms the existence
of possible correlations for each variety separately. Overall, the results reveal the existence of correlations between
different parameters including the one between the dry matter yield, plant height and density.

The extracellular matrix (ECM) and cells have a reciprocal relationship, one shapes the other and vice versa. One of the main challenges of synthetic material systems for developmental cell culturing, organoid and stem cell work includes the implementation of this reciprocal nature.
The largest hurdle to achieve true cell-instructive materials in biomaterials engineering is a lack of spatial and temporal control over material properties and the display of bioactive signals compared to the natural cell environment. ECM-mimicking hydrogels have been developed using a wide
range of polymers, assembly and cross-linking strategies. While our synthetic toolbox is larger than nature, often our systems underperform when compared to ECM systems with natural components like Matrigel. Material properties and three-dimensional structure ill-represent the three-dimensional
ECM reciprocal nature and ligand presentation is an oversimplified version of the complexity found in nature. We hypothesize that the lack of programmable control in properties and ligand presentation forms the basis of this mismatch in performance and analyze the presence of control in current
state of the art ECM-mimicking systems based on covalent, supramolecular and recombinant polymers. We conclude that through combining the dynamics of supramolecular materials, robustness from covalent systems and the programmable spatial control of bio-activation in recombinant ECM materials, the optimal synthetic artificial ECM could be assembled.
The Art and Science of Polymer Brushes: Recent Developments in Patterning and Characterization Approaches
Authors: Panzarasa Guido
Published: June 2017

Polymer brushes are dense arrays of macromolecular chains tethered by one end at a surface. They are at the cutting edge of polymer nanotechnology since the dawn of controlled surface-initiated polymerization techniques unlocked new prospects for the synthesis of polymer brushes with
tailorable properties. More recently, thanks to the growing interest in the use of brushes for the generation of functional surfaces, the need for advanced patterning and characterization approaches rapidly increased. Meeting these needs requires the contribution of experts from different
disciplines: polymer chemistry, surface science, electrochemistry and particle physics. The focus of this review is to highlight recent developments in the field of polymer brushes, specifically the application of photocatalytic lithography as a versatile patterning strategy, the study of
grafted-from polymer brushes by electrochemical methods and, most importantly, the introduction of positron annihilation spectroscopy as a powerful technique for the investigation of the structure of polymer brushes and of their composites with nanoparticles.
Challenges and Perspectives in the Macromolecular Flatland
Authors: Servalli Marco
Published: June 2017

Polymer chemistry has recently welcomed a new addition to its field: the planar macromolecules known as two-dimensional polymers (2DPs). These topologically planar and crystalline monolayer covalent sheets are reminiscent of molecular fishermen's nets and apart from being conceptually
very interesting for the field of macro-molecular chemistry, they also show some potential applications as novel 2D materials. This article reviews how the field has developed five years after the first 2DP was synthesised in 2012. After a brief historical introduction, the main synthetic
approaches will be discussed providing concrete examples of 2DPs and highlighting the challenges associated with the synthesis and especially structural characterisation of these fascinating macro-molecules. Finally an overview on their potential applications such as membranes for gas separation, rewritable molecular paper and miniaturisation of optical devices will be presented.
Comparison of two doses of succinylcholine to facilitate the Laryngeal mask airway insertion under propofol anaesthesia in adult patients undergoing elective minor surgical procedures
Authors: Gunaseelan S , Prabu R Krishna
Published: June 2017

Background: Small dose of succinylcholine combined with propofol facilitates Laryngeal maskairway (LMA) insertion. This study was designed to compare the efficacy of two differentsmall doses of succinylcholine for LMA insertion.Aims and Objectives: The aim of our study is to compare the usefulness of two different doses of succinylcholine to facilitate the insertion of laryngeal mask airway under intravenous anaesthesia.Material and Methods: 70 patients of ASA I and II posted for elective day care procedure under general anaesthesia with Laryngeal mask airway (LMA) were randomly allocated into two groups of 35 each. 35 patients in group PS1 received Inj. propofol 2.0 mg/kg + succinylcholine 0.1 mg/kg (diluted to 2 ml). 35 patients in group PS2 received Inj. propofol 2.0 ml/kg + succinylcholine 0.2 mg/kg (diluted to 2 ml). During insertion of laryngeal mask airway jaw relaxation, gagging/coughing, head and limb movements, presence or absence of laryngospasm and duration of apnoea were noted.Results: Patients in PS2 had better conditions for LMA insertion, reduced the upper airway responses to the LMA insertion, and reduced the supplement doses of propofol compared to PS1.Conclusion: Succinylcholine in 0.2 mg/kg compared to 0.1kg provides optimal conditions for LMA insertion.Asian Journal of Medical Sciences Vol.8(4) 2017 21-26
A Comparative study of the results of conservative treatment versus closed titanium elastic nailing for fractures of shaft of femur in children
Authors: Mukherjee Kunal Subhas , Gupta Amar Nath
Published: June 2017

Background: The ideal treatment of femoral shaft fracture in children is defined as one that controls alignment and length, is comfortable for child and convenient for family and causes the least psychological impact possible.Aims and Objective: The current study was designed to evaluate outcomes prospectively in the first year following treatment of a diaphyseal femoral fracture in children between five and ten years of age treated randomly either by intramedullary titanium elastic nailing or by traction followed by spica cast.Materials and Methods: Out of 48 cases selected according to inclusion/exclusion criteria 6 patients were lost to follow up. Among the rest of 42 patients, 23 were treated by intramedullary titanium elastic nailing and the other 19 conservatively by surface traction. The patients were evaluated at the regular interval of 2, 4, 6 and 8th week post operatively and thereafter every month.Results: There was a significant difference (p< 0.001) in terms of mean hospital stay and mean weight bearing between the two study groups. The findings of outcome and maintenance of reduction, time taken for the evidence of union to appear, the range of movements, the time when weight bearing can be allowed, the functional return of the limb, the rate of complications and the number days of hospital stay were comparable to similar studies conducted earlier.Conclusion: The study concludes that closed pediatric femoral shaft fractures within the ages of 5-10 years can be treated successfully by any methods of traction followed by spica cast or intramedullary titanium elastic nailing. However, because of shorter immobilization period and earlier ambulation, internal fixation with titanium elastic nailing is recommended as the better choice to treat this fracture in school going children.Asian Journal of Medical Sciences Vol.8(4) 2017 32-37

Shunt-dependent hydrocephalus: management style among members of the American Society of Pediatric Neurosurgeons
Authors: Kraemer Mark R. , Sandoval-Garcia Carolina , Bragg Taryn , Iskandar Bermans J.
Published: June 2017

OBJECTIVE

The authors conducted a survey to evaluate differences in the understanding and management of shunt-dependent hydrocephalus among members of the American Society of Pediatric Neurosurgeons (ASPN).

METHODS

Surveys were sent to all 204 active ASPN members in September 2014. One hundred thirty responses were received, representing a 64% response rate. Respondents were asked 13 multiple-choice and free-response questions regarding 4 fundamental problems encountered in shunted-hydrocephalus management: shunt malfunction, chronic cerebrospinal fluid (CSF) overdrainage, chronic headaches, and slit ventricle syndrome (SVS).

RESULTS

Respondents agreed that shunt malfunction occurs most often as the result of ventricular catheter obstruction. Despite contrary evidence in the literature, most respondents (66%) also believed that choroid plexus is the tissue most often found in obstructed proximal catheters. However, free-text responses revealed that the respondents’ understanding of the underlying pathophysiology of shunt obstruction was highly variable and included growth, migration, or adherence of choroid plexus, CSF debris, catheter position, inflammatory processes, and CSF overdrainage. Most respondents considered chronic CSF overdrainage to be a rare complication of shunting in their practice and reported wide variation in treatment protocols. Moreover, despite a lack of evidence in the literature, most respondents attributed chronic headaches in shunt patients to medical reasons (for example, migraines, tension). Accordingly, most respondents managed headaches with reassurance and/or referral to pain clinics. Lastly, there were variable opinions on the etiology of slit ventricle syndrome (SVS), which included early shunting, chronic overdrainage, and/or loss of brain compliance. Beyond shunt revision, respondents reported divergent SVS treatment preferences.

CONCLUSIONS

The survey shows that there is wide variability in the understanding and management of shunt-dependent hydrocephalus and its complications. Such discrepancies appear to be derived partly from inconsistent familiarity with existing literature but especially from a paucity of high-quality publications.
Don't Put All Your Speech-Acts in One Basket: Situating Animal Activism in the Deliberative System
Authors: Parry Lucy J.
Published: June 2017

In this article I offer the deliberative systems approach as a normative and evaluative approach through which to appraise typically ‘non-deliberative’ animal activism. Although such actions can contribute to inclusive deliberation through the political representation of animals, I caution against an over-reliance on such tactics, and interrogate the claim that non-deliberative tactics are essential ingredients for prompting the reflection and reconsideration that animal rights philosophy demands. Instead, non-deliberative activism may serve not only to undermine further deliberation but actually to jeopardise animal protection goals.
