Authors: Rope Robert W. , Pivert Kurtis A. , Parker Mark G. , Sozio Stephen M. , Merell Sylvia Bereknyei
Published: April 2017

Educational needs assessments for nephrology fellowship training are limited. This study assessed fellows’ perceptions of current educational needs and interest in novel modalities that may improve their educational experience and quantified educational resources used by programs and fellows. We distributed a seven-question electronic survey to all United States–based fellows receiving complimentary American Society of Nephrology (ASN) membership at the end of the 2015–2016 academic year in conjunction with the ASN Nephrology Fellows Survey. One third (320 of 863; 37%) of fellows in Accreditation Council for Graduate Medical Education–accredited positions responded. Most respondents rated overall quality of teaching in fellowship as either “good” (37%) or “excellent” (44%), and most (55%) second-year fellows felt “fully prepared” for independent practice. Common educational resources used by fellows included UpToDate, Journal of the American Society of Nephrology/Clinical Journal of the American Society of Nephrology, and Nephrology Self-Assessment Program; others—including ASN’s online curricula—were used less often. Fellows indicated interest in additional instruction in several core topics, including home dialysis modalities, ultrasonography, and pathology. Respondents strongly supported interventions to improve pathology instruction and increase time for physiology and clinical review. In conclusion, current nephrology fellows perceive several gaps in training. Innovation in education and training is needed to better prepare future nephrologists for the growing challenges of kidney care.

Authors:   The Tourism Sciences Society Of Korea, Choi Kyu-Wan , Bang Do-Hyung
Published: April 2017

The diversification of dining-out needs and consumer behavior has emerged as a key issue in marketing to segment and identify consumer groups. This study aims to segment and identify the dining-out consumer market using data from “The Consumer Behavior Survey for Food 2016” collected by the Korea Rural Economic Institute(KREI). In order to segment the dining-out market, we employed a Latent Class Analysis(LCA) selecting five categorical variables including “Expense, Motivation, Place, Frequency and Selection criteria” of Dining-out. As a result of the LCA, six classes were identified as being of an optimal number for markets. This paper provides the evidence necessary to profile the attributes of segmented markets respectively. Moreover, we analyzed segmented market distribution based on dining-out frequency and expense so that two areas have been identified as target consumer markets.

Authors:   The Tourism Sciences Society Of Korea, Kim Tae-Ho , Kim Hak-Seon
Published: April 2017

This study used time series data to evaluate risk management behavior and business performance according to the leverage effect on the operating cycle. This was done analyzing chicken franchise companies from 2013 to 2015. The result was that DFL decreased to 0.96 from a 2.59 level and this showed that the fixed income ratio is increasing. DCL was 1.08 ~ 9.3, and this is an important indicator within the special nature and context of the chicken franchise industry. This special nature was due to the IMF, global financial crisis, and an economic recession. There was also a tendency for new investment plans to be made to enter into new businesses or overseas markets. Also, the financial condition of some companies became significantly lower than in the past due to the launch of new brand. The business cycle also ranged from 8.60 to 22.33 days, and inventory management was better than in the past. The implication of this study is that it is necessary to adjust debt reliance to an appropriate level and to increase the operating profit to a higher level in order to improve the management performance.

The Effect of Economic Job Satisfaction on Turnover Intention in the Hotel Industry
Authors:   The Tourism Sciences Society Of Korea, Kim Jae-Hyun , Kim Kyoung-Bae , Kang Shin-Young
Published: April 2017

This research studies the effect of economic job satisfaction factors such as cash worth, compensation worth, and future worth on turnover intention. To fulfil this research goal, three research hypothesis were established: H1) According to the demographic variables of employees, the level of economic job satisfaction will be different. H2) The level of economic job satisfaction will be different depending on the job environment of the employee. H3) The economic job satisfaction of employees will affect their turnover intention. 244 questionnaires were distributed to Hotel employees in five-star hotels. The research identified a significant relationship between an employee’s economic job satisfaction and their subsequent turnover intention. Unsatisfied cash worth and unsatisfied compensation worth affected the employee’s turnover intention. This indicates that it is material rewards such as payroll or incentives that determine turnover intention rather than subjective factors. Even in situations of low job security and economic downturn, it is likely that hotel employees who do not believe they are receiving the proper compensation for their work could change jobs. For effective personnel management, hotel executives should introduce a personnel management system that is suited to each individual employee rather than a single compensation and promotion system for all hotel employees. Managers need to pay close attention to minimizing the stress that results from clashes between hotel employees and supervisors of job performance or from excessive overtime. Apart from unidirectional personnel management, it is essential that the company diversify their compensation system not just in terms of payroll but also in terms of job performance. This should be done according to the company management style and the company size. Therefore, hotels must find a measure that could prevent turnover intention by securing cash worth and compensation worth for hotel employees that can be applied to current hotels.

Published: April 2017

This paper examined the responses of consumers toward personalization of branded mobile apps in the context of the coffee industry based on privacy-calculus theory and a technology acceptance model (TAM). Specifically, the current research identified the effects of a consumer’s perceived risk, perceived usefulness, and perceived ease of use for personalized branded mobile apps on trust and continuance intention to use apps. Also this paper performed Importance-Performance Analysis (IPA). A total of 431 questionnaires were collected from participants who had used coffee brand mobile apps and these samples were analyzed. The findings were as follows: First, while consumer’s perceived usefulness and perceived ease of use positively influenced trust in mobile apps, the perceived risk negatively influenced trust in mobile apps. Second, trust in mobile apps positively affected the continuance intention to use apps. These findings offer several implications for developing strategies for the further personalization of branded mobile apps.
Folates: Key Nutrients to Remember
Authors: Freha Gourchala , Fatma Mihoub , Cherifa Henchiri
Published: April 2017

Folic acid or vitamin B9 or pteroylglutamic acid, is a relatively simple molecule with two characteristics; firstly, it must be reduced by 2 or 4 hydrogen atoms to be metabolically active which makes it sensitive to oxidation and must be protected by ascorbic acid, secondly it may include in addition to the constituent residues of the molecule, 1-7 glutamate residue at one of its ends. These polyglutamate forms that make up the largest share of food folate, must be deconjugated by a specific enzyme present in the intestinal lumen before being absorbed in the jejunum. It is in the methylated form after passing through the enterocyte it is transported in the blood, excreted in bile and reabsorbed. It must be demethylated to integrate folic cell cycle and methyl transfer, that allows the synthesis of methionine (only possible in the presence of vitamin B12), purine, serine and especially thymidylic acid, constitutive DNA. As a methyl donor that plays a fundamental role in cerebral and nervous metabolism. Folates are involved in cell division thus; any folic acid deficiency causes a slowdown in rapid multiplication systems which may lead to red blood cell disorders (macrocytic anemia), immunity, and neural tube defects, in addition to physiological disorders (cardiovascular, cancer ...). Folic acid supplementation appears to allow the correction of these disorders.

The requirement for objective techniques to observe physical action in its distinctive measurements has prompted the improvement and broad utilisation of motion sensors called Inertial Measurement Units (IMUs), which measures bodily movements. However, although these sensors have been utilised to measure postural balance in both clinical and some specific sports, little or no effort have been made to apply these sensors to the measurement of other physiological indicators in the sport of archery. This study aims to ascertain the postural balance, hand movement, muscular activation as well as heart rate of an archer. An archer was instructed to perform two balance standings, two hand movements and his muscular activations of flexor and extensor digitorum, as well as heart rate, were recorded using Shimmer sensors. The mean movement of x and y-axis of the archer was used to correlate with the Pearson correlation for testing the validity of the sensors. Kolmogorov/Smirnov test was utilised to measure the reliability of the sensors over test re-test in two different tests. The coefficient of determination indicates some positive and negative significant relationships between some indicators. The Kolmogorov/Smirnov test re-test reveals a significant difference between all the indicators in both tests A and B, p < 0.001. The archer was able to present two types of postural standings and exhibited two hands movement while holding the bow. However, his heart rate demonstrated some variability during the executions of the movement in both tests. Thus, it could be concluded that the fusion sensors are reliable in measuring the aforementioned physiological indicators.

Authors: Shukla Niharika
Published: April 2017

The present investigation aimed to find out the association among yield and its components and to sort out the traits that are directly or indirectly contributing towards yield in landraces of maize genotypes. The eighty eight (88) maize germplasm collections were used in present study during Kharif -2012 and Kharif -2013 in RCBD design. Pooled data and standard statistics were employed (means, ranges, GM±SE, standard error and coefficient of variation etc.) for analysis of the seventeen quantitative traits to have a reflection of the level of genetic variability. A considerable amount of variability was found among germplasms for various important traits viz. plant height, ear weight, ear length, 1000 kernel weight similarly grain yield per plant etc. grain yield exhibited positive and highly significant correlation with ear height, days to female flower initiation, days to 50% male flower initiation, days to 50% female flower initiation, days to maturity, 1000 grain weight, ear weight at genotypic and phenotypic level. Maximum phenotypic correlation coefficient was recorded by cob diameter (0.955) followed by days to female flower initiation (0.758), plant height (0.718*) and days to male flower initiation (0.679).Path analysis indicated that the character ear height (0.410) recorded highest of the direct effect followed by biological yield per plant (0.408), harvest index (0.328), days to female flower initiation (0.32), prop root (0.149) and 1000 kernel weight (0.136), so such traits may be rewarding and they should be given importance while practicing selection, aimed at improving grain yield per plant in maize. The genotypes JLM 22 was to be found best for high yield by considering all yield contributing traits followed by JLM 51, HKI 1344, CML 429, CML 470, JLM 30 JLM 2 and these can be utilized in further breeding programmes for producing single cross hybrids in Maize.

Published: April 2017

Eighty genotypes of blackgram comprising landraces, varieties and local cultivars collected from different locations were studied for genetic divergence by using D2 statistic. The genotypes were grouped into twelve clusters, cluster I had maximum of 41 genotypes followed by cluster V and VI with 11 genotypes in each. Clusters VIII, XI and XII had one genotype each. The maximum intra cluster distance was found in cluster I. The divergence within the cluster indicates the divergence among the genotypes in the same cluster. Maximum inter-cluster distance was found between cluster III and XI followed by cluster XI and VII, XI and X, XI and III, indicating efficient breeding program can be undertaken to improve productivity and other yield attributes by exploiting heterosis breeding program by selecting superior genotypes in segregating generation. Number of branches, plant height, 100 seed weight and number of clusters per plant had maximum contribution to divergence. Cluster VI had highest mean value for seeds per pod, clusters per plant and pods per plant. Cluster IV recorded highest mean value for seed yield per plant and number of branches per plant. Due importance should be given for these traits for selection of parents for efficient breeding programmes. Lu 18 and VZM 189/65 may serve as potential parents in getting transgressive segregants.

Published: April 2017

To solve the shorter shelf life, high contamination, poor quality, low field performance and processing solid carrier in carrier based bioinoculant formulation had necessitated the shifting of carrier based inoclants to liquid inoculants technology. Three different polymeric additives; polyvinyl pyrrolidone, gum arabic and glycerol were evaluated for their ability to support growth and promote survival ofliquid inoculants (Rhizobium sp. strain MB1503) during the storage. All liquid rhizobial inoculants prepared in amended media showed higher viable count in comparison to inoculants prepared in YEMB (control) at 180 d of storage. Maximum survival was observed in inoculants prepared in YEMB amended with2% PVP, 2% GA and1% GA. Mungbean (Vigna radiata L.) seeds treated with 90 d old liquid rhizobial inoculant of strain MB1503 amended with 1% PVP or 2% glycerol enhanced plant growth as compared to uninoculated control. The present investigation revealed that treatments inoculated with 90 d old inoculant + amendments (added before or after the growth) were significantly better with respect to nodule weight, shoot weight and total plant nitrogen as compared to uninoculated control/treatment.

Published: April 2017

Random Amplified Polymorphic DNA molecular markers analysis of Spodoptera litura larvae population from seven major soybean growing regions of India revealed, populations from Hyderabad and Indore, shared cent per cent similarity, Pune and Parbhani populations showed 90 per cent similarity, Adilabad population shared 83 per cent similarity with both Hyderabad and Indore populations, while Dharwad and Belagavi populations showed 72 per cent similarity. The lowest genetic similarity value was observed between Dharwad and Parbhani populations (46%). It is clear from the similarity analysis more than 46 per cent similarity between populations of the S. litura from major soybean growing states, demonstrate mediocre genetic differences between the populations. Though much genetic diversity was not observed between S. litura populations, topological and temporal factors perhaps influenced the existed diversity among the populations.

Revealing Phenomena of Heat Energy, Levity, Gravity and Photons Characteristic Current to Light on Dealing Matter to Sub-Atom
Authors: Ali Mubarak
Published: April 2017

Technology is in the way to reaching in its climax but the basic understanding of science in many phenomena is still awaited. Scientific research reveals strong analogy between electron and photon. Atoms that execute suitable electronic transitions, on absorbing heat energy at shunt level, excite their electrons. De-excitation of an electron under the gravitational force of its nucleus, where inertia is involved, results depicting energy in the shape like Gaussian distribution. The wavelength of photon remains in inter-state electron’s gap where the source of generating energy in wave-like fashion is due to electronic transitions under confined electron-dynamics; energy configures under electron’s trajectory in the excitation period is due to inertia-levitation-inertia behaviours while energy configures under electron’s trajectory in the de-excitation period is due to inertia-gravitation-inertia behaviours. Silicon atom is a model system of it. Uninterrupted confined inter-state electron-dynamics results into configure energy in a wave-like fashion that can travel immeasurable length and on interruption from the point of generation, it becomes a photon. Such photons increase wavelength on decreasing energy while travelling through inherently built gap of splitted inert gas atoms where they give light (glow) on reaching wavelength in the visible range. Here, I discuss that heat energy is due to merged photons, photons characteristic current are due to photons having wavelength in inter-state electron’s gap and light is due to photons, following the wavelength in the visible range. Force of repulsion or attraction in certain materials engages the phenomenon of levitism or gravitism where inertia is exempted. All structural motifs and dynamics are subjected to characteristic photons as long as atoms are under neutral behavior of field force. A structural design delivers straight-forward application on dealing photons at different wavelengths. Here, materials science explores matter at electronic level while absorbing heat energy and generating photon energy. Thus, devise science to describe.
Graph-based Semi-supervised Learning for Indoor Localization Using Crowdsourced Data
Authors: Zhang Liye , Valaee Shahrokh , Xu Yu Bin , Ma Lin , Vedadi Farhang
Published: April 2017

Indoor positioning based on the received signal strength (RSS) of the WiFi signal has become the most popular solution for indoor localization. In order to realize the rapid deployment of indoor localization systems, solutions based on crowdsourcing have been proposed. However, compared to conventional methods, crowdsourced RSS values are more erroneous and can result in large localization errors. To mitigate the negative effect of the erroneous measurements, a graph-based semi-supervised learning (G-SSL) method is used to exploit the correlation between the RSS values at nearby locations to estimate an optimal RSS value at each location. Before using the G-SSL method, the Linear Regression (LR) algorithm is proposed to solve the device diversity problem in crowdsourcing system. Since the spatial distribution of the APs is sparse, the Compressed Sensing (CS) method is applied to precisely estimate the location of the APs. Based on the location of the APs and a simple signal propagation model, the RSS difference between different locations is calculated and used as an additional constraint to improve the performance of G-SSL. Furthermore, to exploit the sparsity of the weights used in the G-SSL, we use the CS method to reconstruct these weights more accurately and make a further improvement on the performance of the G-SSL. Experimental results show improved results in terms of the smoothness of the radio map and the localization accuracy.
Mining Productive-associated Periodic Frequent Pattern in Body Sensor Data for Smart Home Care
Authors: Ismail Wala , Hassan Mohammad Mehedi
Published: April 2017

The understanding of various health-oriented vital sign data generated from body sensor networks (BSN) and discovery of the association between the generated parameters is an important task that may assist and promote important decision making in healthcare. For example, in a smart home scenario where the occupants’ health status is continuously monitored remotely, it is essential to provide required assistance when an unusual or critical situation is detected in their vital sign data. In this paper, we present an efficient approach to mine the incomplete (partial) periodic patterns obtained from BSN data. In addition, we employ a correlation test on the generated patterns and introduce the productive-associated partial periodic frequent patterns as the set of correlated partial periodical frequent items. The combination of these measures has the advantage of empowering healthcare providers and patients for quality of diagnosis, and also for better treatment and smart care, especially for the elderly people at smart home. We developed an efficient algorithm named PPFP-Growth (Productive Periodic Frequent Pattern growth) to discover all productive associated partial periodic patterns using these measures. PPFP-Growth is efficient, and the productiveness measure removes uncorrelated periodic items. An experimental evaluation on synthetic and real datasets shows the efficiency of the proposed PPFP-Growth algorithm, and can filter a huge number of partial periodic patterns to reveal only the correlated ones.

Published: April 2017

Real-time strategy (RTS) game has proposed many challenges for AI research for its large state spaces, enormous branch factors, limited decision time and dynamic adversarial environment. To tackle above problems, the method called Adversarial Hierarchical Task Network planning (AHTN) has been proposed and achieves favorable performance. However, the HTN description it used cannot express complex relationships among tasks and impacts of environment on tasks. Moreover, the AHTN cannot handle task failures during plan execution. In this paper, we propose a modified AHTN planning algorithm named AHTNR. The algorithm introduces three elements essential task, phase and exit condition to extend the HTN description. To deal with possible task failures, the AHTNR first uses the extended HTN description to identify failed tasks. And then a novel task repair strategy is proposed based on historical information to maintain the validity of previous plan. Finally, empirical results are presented for the μRTS game, comparing AHTNR to the state-of-the-art search algorithms for RTS games.

Published: April 2017

Injury is a leading cause of death and disability globally. After an acute hospitalization for an injury, a care transition model has been shown to reduce mortality and morbidity but these are uncommon in a low and middle income setting. When planning a post hospitalization care plan, many health management factors should be taken into account as they can impact outcome. This manuscript delineates a 5 Domains of Healthcare Management or ‘5 Domains’ which should be addressed in this care transition model. The literature behind each of these domains and their impact on post hospitalization outcomes along with a case study of a care transition plan for a low income country is described.

Published: April 2017

Prone positioning to optimise ventilation in a patient with acute respiratory distress syndrome (ARDS) is not a contraindication to inter‐hospital transfer, and may be life‐saving. Basic safety precautions must be maintained throughout the transfer. Based on a successful case of prone transfer, we would advocate that transport teams consider training specifically for this scenario.

Published: April 2017

Palatal expansion has a unique role in dentofacial therapy. The rapid Maxillary expansion which is a type of skeletal expansion involves the opening of the mid-palatal suture and movement of the palatal shelves away from each other. Selection of appropriate appliance should be made by preparing a list of criteria depending on the biomechanical requirements of RME. Rapid expansion affects the maxillary complex, palatal vaults, maxillary teeth, adjacent periodontal structures to get desired expansion in the maxillary arch. Maxillary transverse deficiency in adults is a malocclusion of relatively high prevalence in orthodontics. The rapid maxillary expansion (RME) surgically assisted is considered the preferred procedure to correction of this alteration in patients skeletally mature. This review discusses the types of palatal expansion and skeletal and soft tissue effects of palatal expansion.

Al hablar del habitante de calle, resulta importante mencionar que es un fenómeno que ha tenido presencia milenaria, y que ha estado siempre permeado por las lógicas sociales de gobernanza, religión, cultura y economía. Han sido tan diversas las representaciones que se han tenido de esta población, que hoy inclusive sobreviven algunas de esas ideas que han hecho difícil su abordaje y comprensión. El objetivo de este texto es dar a conocer las reflexiones que han surgido de un ejercicio inicial de formación investigativa, en cuanto al fenómeno habitante de calle en Medellín. Para esta acción se revisaron algunos artículos sobre esta población, y se realizó una pequeña pasantía por el sistema de Atención al Habitante de Calle de Medellín, de donde surgieron algunas ideas referentes al concepto, historia y estrategias de intervención que se han implementado desde las diferentes administraciones para intentar dar solución a dicho fenómeno.
Transparencia del gasto fiscal en Colombia
Authors: Bautista Jairo Alonso , Sepúlveda Reyes Didier Antonio
Published: April 2017

El presente artículo tiene como propósito analizar los procesos de transparencia de la información producida alrededor del gasto tributario ejecutado por el Gobierno Nacional Central en Colombia, y las consecuencias fiscales que se derivan de su administración. Considerando que la transparencia fiscal es el fundamento para tomar adecuadas decisiones de política y el factor clave para mejorar la confianza de los ciudadanos y legitimar la estructura tributaria, su estudio es altamente pertinente en la medida en que a diferencia del tradicional presupuesto de gastos, el gasto tributario no es fácilmente representable en las cuentas fiscales, por tanto, la relación entre éste último (el cual se entiende como un trato preferente en el tributo, más que como un gasto tributario) y los efectos sociales y económicos deseados con dichos tratamientos preferenciales, no es clara y, además, puede causar profundas desigualdades en el pago de los tributos.En este sentido, el documento hace una revisión de las principales aproximaciones teóricas al concepto de transparencia fiscal, y busca establecer la importancia que dicha noción tiene para el estudio de los gastos tributarios, y los desarrollos que ambos elementos han tenido en la gestión presupuestal en Colombia. El artículo es documento de reflexión y surge de los debates del grupo de investigación Ciudadanía y Finanzas Públicas de la Escuela Superior de Administración Pública, ESAP.

Climate change has changed planting structure greatly in cold regions. Studies are needed that understand the relationship between climate change and agriculture in cold regions and to serve as references for studies of the impact of climate change on agriculture in similar areas. This paper uses Heilongjiang Province as a case study; seven test methods and mutual information were used to analyse the variation trend, abrupt changes and relationship between climate and planting structure. The following was concluded. (1) The precipitation trend was not significant; temperature showed a significant upward trend, the minimum temperature showed the sharpest increase. (2) The proportion of area planted in rice and maize showed a significant upward trend. The trend of rice was the most pronounced, the trend of wheat significantly decreased. (3) Abrupt changes in temperature occurred in the 1980s; abrupt changes in wheat were concentrated at the end of the 1990s. (4) The relationship between temperature and planting structure was stronger than that of precipitation, and the relationship between minimum temperature and planting structure was stronger than that of maximum temperature. The results show that temperature variables, especially minimum temperature, are the main factors affecting the change in planting structure in cold regions.
Removal of calcium and magnesium ions from shale gas flowback water by chemically activated zeolite

Shale gas has become a new sweet spot of global oil and gas exploration, and the large amount of flowback water produced during shale gas extraction is attracting increased attention. Internal recycling of flowback water for future hydraulic fracturing is currently the most effective, and it is necessary to decrease the content of divalent cations for eliminating scaling and maintaining effectiveness of friction reducer. Zeolite has been widely used as a sorbent to remove cations from wastewater. This work was carried out to investigate the effects of zeolite type, zeolite form, activation chemical, activation condition, and sorption condition on removal of Ca2+ and Mg2+ from shale gas flowback water. Results showed that low removal of Ca2+ and Mg2+ was found for raw zeolite 4A and zeolite 13X, and the efficiency of the mixture of both zeolites was slightly higher. Compared with the raw zeolites, the zeolites after activation using NaOH and NaCl greatly improved the sorption performance, and there was no significant difference between dynamic activation and static activation. Dynamic sorption outperformed static sorption, the difference exceeding 40% and 7–70% for removal of Ca2+ and Mg2+, respectively. Moreover, powdered zeolites outperformed granulated zeolites in divalent cation removal.
Recycling of end-of-life reverse osmosis membranes by oxidative treatment: a technical evaluation

Published: April 2017

The adverse impacts caused by the disposal of thousands of tonnes per annum of reverse osmosis (RO) membranes modules have grown dramatically around the world. The objective of this study was to evaluate the technical feasibility of recycling by chemical oxidation of end-of-life RO membranes for applications in other separation processes with specifications less rigorous. The recycling technique consisted in to cause a membrane exposition with oxidant solutions in order to remove its aromatic polyamide layer and subsequent conversion to a porous membrane. The recycling technique was evaluated by water permeability and salt rejection tests before and after the oxidative treatments. Initially, membranes' chemical cleaning and pretreatment procedures were assessed. Among factors evaluated, the oxidizing agent, its concentration and pH, associated with the oxidative treatment time, showed important influence on the oxidation of the membranes. Results showed that sodium hypochlorite and potassium permanganate are efficient agents for the membrane recycling. The great increased permeability and decreased salt rejection indicated changes on membranes' selective properties. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), atomic force microscopy (AFM), and contact angle characterization techniques revealed marked changes on the main membranes' physical–chemical properties, such as morphology, roughness and hydrophobicity. Reuse of produced effluents and fouling tendency of recycled membranes were also evaluated.
Humeral Tip-apex-distance as a Prognostic Marker for Proximal Humeral Fractures in 203 Patients
Authors: Saul Dominik , Himmelmann Tobias , Dresing Klaus
Published: April 2017

Background:

Humeral head fractures and their postoperative outcome remain a challenging problem in surgical daily routine. Predictive factors for loss of fixation are rare.

Objective:

Determination of predictive factors for the failure of osteosynthesis with the loss of fixation or migration of screws in humeral head fractures.

Method:

From 1995 to 2011, 408 patients with proximal humeral fractures [mean age 66.6 years, 50.9-82.3 years] and osteosynthesis were analyzed. Two hundred and three received open reduction internal fixation (ORIF) with the PHILOS®plate. The non-locking plate was used in 80, the locking plate in 16 and humeral head prosthesis in 26 patients, in addition to 23 patients undergoing other procedures. Intraoperative reduction that achieved an anatomical alignment of the medial aspect of the humerus (humeral calcar) was assessed in 94 patients by postoperative X-ray analysis. The loss of fixation was evaluated by a follow-up of three to five X-rays and measurement of the humeral tip-apex-distance (HTAD).

Results:

For stable fixed fractures with an intact calcar, percentual HTAD was significantly higher than for unstable fixed fractures (p=0.04). Morbidity, such as hypertension, orthopedic operations or diabetes, strongly influenced the HTAD, while postoperative passive motion treatment modestly affected the HTAD over time.

Conclusion:

The anatomic reconstruction of the calcar, leading to stable fixation of humeral head fractures, can significantly prevent an overproportioned decrease in the HTAD in postoperative X-rays and seems to be vital in multimorbid patients. Measurement of the HTAD over time delivers a tool for early detection of secondary loss of fixation.
