Published: September 2018

BACKGROUND

Heterotopic ossification (HO) is a significant complication for wounded warriors with traumatic limb loss. Although this pathologic condition negatively impacts the general population, ectopic bone has been observed with higher frequency for service members injured in Iraq and Afghanistan due to blast injuries. Several factors, including a traumatic insult, bioburden, tourniquet and wound vacuum usage, and bone fractures or fragments have been associated with increased HO for service members. A large combat-relevant animal model is needed to further understand ectopic bone etiology and develop new pragmatic solutions for reducing HO formation and recurrence.

OBJECTIVE

This study outlines the optimization of a blast system that may be used to simulate combat-relevant trauma for HO and replicate percussion blast experienced in theater.

METHODS

We tested the repeatability and reproducibility of an air impact device (AID) at various pressure settings and compared it with a model of blunt force trauma for HO induction. Furthermore, we assessed the ability of the higher-power air delivery system to injure host tissue, displace metal particulate, and disperse bone chips in cadaveric sheep limbs.

RESULTS

Data demonstrated that the air delivery setup generated battlefield-relevant blast forces. When the AID was charged to 40, 80, and 100 psi, the outputs were 229 (SD 13) N, 778 (SD 50) N, and 1085 (SD 114) N, respectively, compared with the blunt force model which proposed only 168 (SD 11) N. For the 100-psi AID setup, the force equaled a 5.8-kg charge weight of trinitrotoluene at a standoff distance of approximately 2.62 m, which would replicate a dismounted improvised explosive device blast in theater. Dispersion data showed that the delivery system would have the ability to cause host tissue trauma and effectively disperse metal particulate and host bone chips in local musculature compared with the standard blunt force model (13 mm vs 2 mm).

CONCLUSIONS

Our data showed that a high-pressure AID was repeatable or reproducible, had the ability to function as a simulated battlefield blast that can model military HO scenarios, and will allow for factors including blast trauma to translate toward a large animal model.

Published: September 2018

BACKGROUND

Silent brain infarction (SBI) is defined as the presence of 1 or more brain lesions, presumed to be because of vascular occlusion, found by neuroimaging (magnetic resonance imaging or computed tomography) in patients without clinical manifestations of stroke. It is more common than stroke and can be detected in 20% of healthy elderly people. Early detection of SBI may mitigate the risk of stroke by offering preventative treatment plans. Natural language processing (NLP) techniques offer an opportunity to systematically identify SBI cases from electronic health records (EHRs) by extracting, normalizing, and classifying SBI-related incidental findings interpreted by radiologists from neuroimaging reports.

OBJECTIVE

This study aimed to develop NLP systems to determine individuals with incidentally discovered SBIs from neuroimaging reports at 2 sites: Mayo Clinic and Tufts Medical Center.

METHODS

Both rule-based and machine learning approaches were adopted in developing the NLP system. The rule-based system was implemented using the open source NLP pipeline MedTagger, developed by Mayo Clinic. Features for rule-based systems, including significant words and patterns related to SBI, were generated using pointwise mutual information. The machine learning models adopted convolutional neural network (CNN), random forest, support vector machine, and logistic regression. The performance of the NLP algorithm was compared with a manually created gold standard.

RESULTS

A total of 5 reports were removed due to invalid scan types. The interannotator agreements across Mayo and Tufts neuroimaging reports were 0.87 and 0.91, respectively. The rule-based system yielded the best performance of predicting SBI with an accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 0.991, 0.925, 1.000, 1.000, and 0.990, respectively. The CNN achieved the best score on predicting white matter disease (WMD) with an accuracy, sensitivity, specificity, PPV, and NPV of 0.994, 0.994, 0.994, 0.994, and 0.994, respectively.

CONCLUSIONS

We adopted a standardized data abstraction and modeling process to developed NLP techniques (rule-based and machine learning) to detect incidental SBIs and WMDs from annotated neuroimaging reports. Validation statistics suggested a high feasibility of detecting SBIs and WMDs from EHRs using NLP.

Published: September 2018

BACKGROUND

Young adults who experience homelessness are exposed to environments that contribute to risk behavior. However, few studies have examined how access to housing may affect the health risk behaviors of young adults experiencing homelessness.

OBJECTIVE

This paper describes the Log My Life study that uses an innovative, mixed-methods approach based on geographically explicit ecological momentary assessment (EMA) through cell phone technology to understand the risk environment of young adults who have either enrolled in housing programs or are currently homeless.

METHODS

For the quantitative arm, study participants age 18-27 respond to momentary surveys via a smartphone app that collects geospatial information repeatedly during a 1-week period. Both EMAs (up to 8 per day) and daily diaries are prompted to explore within-day and daily variations in emotional affect, context, and health risk behavior, while also capturing infrequent risk behaviors such as sex in exchange for goods or services. For the qualitative arm, a purposive subsample of participants who indicated engaging in risky behaviors are asked to complete an in-depth qualitative interview using an interactive, personalized geospatial map rendering of EMA responses.

RESULTS

Recruitment began in June of 2017. To date, 170 participants enrolled in the study. Compliance with EMA and daily diary surveys was generally high. In-depth qualitative follow-ups have been conducted with 15 participants. We expect to recruit 50 additional participants and complete analyses by September of 2019.

CONCLUSIONS

Mixing the quantitative and qualitative arms in this study will provide a more complete understanding of differences in risk environments between homeless and housed young adults. Furthermore, this approach can improve recall bias and enhance ecological validity.

The function and importance of the DCT Gdańsk in terms of intermodal transportation development in Poland
Authors: Kubowicz Daria
Published: September 2018

Intermodal transportation is becoming more and more willingly used in the goods supply chain in view of its specific, flexible characteristics. In Poland, intermodal transportation is based primarily on land-sea and rail-road transportation, using mostly containers. The most frequently used containers in 2017 were the 40-feet containers which accounted for over 57% of all containers transported. Contribution of the railway transportation in intermodal transportation is increasing every year. Despite the slow growth, both, planned as well as already carried out investments in intermodal terminals, indicate continuous growing pattern. Many operators strive to improve the technical condition of nodal and linear infrastructure that leads to raising the quality of services provided. Large number of investments aimed at improving the functioning of intermodal transportation in Poland are made by PKP PLK S.A which is the conductor rail operator. The most important of them include improvement of the railway lines technical condition of the major routes, that would increase the average operational speed. The largest intermodal terminal in Poland is the DCT Gdańsk located in the Northern Port in Gdańsk. The annual transshipment ability of the terminal after the investments made is set at 3 million TEU. The terminal is connected with the hinterland by road and rail connections. Due to high quality technical equipment it is able to serve up to 9 trains a day which adds up to almost 300 trains per month. It provides railway connection to almost all overland intermodal terminals in the country. DCT Gdańsk gladly invests in development of the railway transportation and endeavour to achieve rail system development not only at the terminal, but also throughout Poland.
Environmental activities carried out in the supply chain
Authors: Maryniak Anna
Published: September 2018

In recent years the customers, local communities, international organizations, government agencies and other stakeholders have put pressure on the world of business for environmental protection. The aim of the study is to determine to what extent enterprises have re-evaluated the approach to management in the supply chain towards “green” activities. The research was conducted among entities registered in Poland. The study, among other things, established that most frequent activities are those implemented in the area of product policy, while the least frequent activities are those implemented in the line of producer-supplier activities. This may indicate a low level of development of green chains and an easier way to enforce green behaviour from entities from the upper section of the supply chain.
Results obtained through the implementation of pro-environmental activities versus the level of supply chain integration
Authors: Maryniak Anna
Published: September 2018

This study focuses on aspects related to green supply chain management, including the level of supply chain integration and the effect of implementation of pro-environmental activities carried out among vertically integrated entities. The subject of the research were Polish manufacturing enterprises. Based on the obtained results, it has been proved that a higher level of integration in the supply chain leads to higher pro-environmental results obtained for the surveyed enterprises, co-operators in the supply chain and the further and closer environment of the enterprise, including the natural environment itself. As part of the conducted research, it was also determined that the main beneficiaries of the benefits resulting from the implementation of pro-environmental activities are internal stakeholders.

Published: September 2018

The object of the study is to strip mill hot-rolled steel mill in Huta ArcelorMittal Poland in Cracow. The paper presents a model rolling mill logistic system which incorporates the characteristic of its subsystems: the movement and storage of materials. System components are mill production equipment, transportation, storage interop and finished products. Logistic approach requires inter alia: minimizing the transition time of materials through the system, minimizing inventories to production and should have reduced energy consumption and production tools used to manufacture the final product. For the model should be the basis to formulate the logistic system of strip mill, taking into account both the technological and economical operation of the test mill. To accomplish the task of material flow simulator was used Dosimis-3.

Businesses operating in turbulent environments must look for ways that will allow them to survive, grow, succeed and increase efficiency. The need to be effective, flexible and innovative is imperative for the functioning and development of modern enterprises. Efficiency is characterized by a wide range of content, as it relates to effects, goals, expenditures and costs in terms of structure and dynamics. Efficiency is an ambiguous and differently interpreted notion of economy, business, process, finance, motivation or logistics. Logistics is an efficiency orientation based on the comprehensive analysis and shaping of the optimum level and structure of outlays and their transformation into costs, where the primary role is to strive for the right level and quality of service and customer service. Considering the effectiveness issue it should be noted that it has not only a real but also a potential dimension. It is therefore important in the systemic sense of the effectiveness of logistics to study not only actual effectiveness but also potential effectiveness. In terms of the subject matter studied, the following basic characteristics of the system are important: stability, adaptability and innovation. Therefore, the article describes the theoretical bases of effectiveness and the place and importance of innovative in efficiency, with particular emphasis on logistics.
