Published: May 2022

The OBJECTIVE was to study the state of serum matrix metalloproteinase and their prognostic value in closed spleen injuries in the immediate postoperative period.

METHODS AND MATERIALS. Retrospective analysis of the course of the immediate postoperative period of 126 patients with closed spleen injuries was carried out in this work. They were treated in the emergency surgery department. Taking into account that the main leading factor affecting the immediate postoperative period in such patients is the time factor, i.e. the time of delivery to the medical institution from the moment of injury, we divided all patients into two groups: group A – the time of delivery to the medical institution did not exceed one hour from the moment of injury. This group was divided into two subgroups: А1 – isolated injuries and А2 – combined injuries. The second group, group B, included patients whose delivery time exceeded one hour, which were also divided into two subgroups: B1 – isolated injuries and B2 – combined injuries. During the study, the level of the tissue inhibitor of metalloproteinases-1 (TIMP-1), matrix metalloproteinases-2, -7, -9 (MMPs-2, -7, -9) in blood serum was determined.

RESULTS. As a result of the study, it was found that changes in TIMP-1 and MMPs-2, -7, -9 in blood serum depend on the time of delivery of the patient and the presence or absence of combined lesions.

CONCLUSION. Changes in levels of the tissue inhibitor of metalloproteinases-1, matrix metalloproteinases-2, -7, -9 can be considered as predictors of development of complications and fatal outcomes in patients with closed spleen injuries in the immediate postoperative period. Changes in these indicators depend on the time of delivery of the patient and the nature of the injury. The reduction of the tissue inhibitor of metalloproteinases below 1231 ng/ml is an unfavourable indicator of death.

INTRODUCTION. Patients with peritonitis complicated by severe sepsis and septic shock determine the mortality rate of a general surgical hospital. The role and place of the Damage control technique in this category of patients remain debatable.

The OBJECTIVE was to analyze the use of tactics of staged surgical treatment in patients with peritonitis and septic shock.

METHODS AND MATERIALS. On the base of the Saint-Petersburg I. I. Dzhanelidze Research Institute of Emergency Medicine, we conducted a prospective randomized study of the effectiveness of various approaches to the treatment of patients with non-traumatic peritonitis and septic shock, who, after elimination of the primary source, need to restore intestinal continuity. The study included 37 patients, their mean age was (69±14) years, women were 19 (51 %). The patients were divided into 2 groups: the study group (n=14) included patients treated with the Damage Control (DC) principle, in the comparison group (n=23), primary surgery was performed in full. Both groups are representative in terms of demographics, comorbidity, severity of peritonitis and organ dysfunction.

RESULTS. The groups differed significantly in the duration of preoperative preparation (p=0.028) and surgery (p=0.025). Mortality rate among patients who used DC tactics was 2 times lower (35.6 vs. 73.9 %) (p=0.038). When assessing the indicators of systemic hypoperfusion, a difference was noted in the dynamics of lactate (p=0.048) and INR (p=0.007) values   during the first three days of the postoperative period. Accordingly, in patients who underwent staged treatment, there was a positive dynamics in SOFA values   (p=0.049) from the 3rd day, and by the 7th day of the postoperative period in most patients, this indicator did not exceed 2 points (p=0.048). During staged surgical treatment, a constant increase in the Horvitz index was recorded from the second day of the postoperative period, while in the control group, the dynamics of this indicator was negative (p=0.041).

СONCLUSIONS. Damage control tactics is safe and can be used in the treatment of general surgical patients with non-traumatic peritonitis and septic shock. Reducing the duration of preoperative preparation, reducing the volume of surgical intervention and, consequently, the duration of the operation allow reduce the time for eliminating signs of systemic hypoperfusion and organ dysfunction, which reduces the rate of death.

The clinical case of treatment of the patient with gallstone disease complicated by phlegmonous calculous cholecystitis, choledocholithiasis, obstructive jaundice and purulent cholangitis is presented. The combination of such dangerous complications requires urgent surgical treatment, the minimum amount of which is cholecystectomy and bile duct external drainage at the first stage of treatment. In this case, the simultaneous elimination of choledocholithiasis was considered unjustifiably traumatic and not rational due to the large size of the concretion (13 mm). We also decided to refuse the wide endoscopic papillosphincterotomy. At the second stage of treatment, under the control of transpapillary choledochoscopy, nanoelectroimpulse choledocholithotripsy was performed with the destruction of a dense concretion of choledochus without damaging the surrounding tissues and the sphincter apparatus of the large papilla of the duodenum, which eliminates the likelihood of complications arising after papillosphincterotomy.

Published: May 2022

Ewing’s sarcoma is a malignant bone tumor. It occurs more often in teenagers between 10–15 years old and metastasizes to the lungs and nervous system. Heart disease is atypical and occurs in only a few cases. We present a clinical case of late diagnosis of Ewing’s sarcoma in a 26-year-old patient with metastases in the left side of the heart. According to instrumental tests, hypermobile, ribbon-like formations were visualized on the cusps of the aortic and mitral valves with damage to the chordal apparatus. Coronary angiography was performed with embolextraction from the middle third of the left anterior descending artery and its diagonal branch, due to the clinical picture of anterior acute myocardial infarction with ST segment elevation. An urgent cardiac surgery was performed, in the attempt to prevent fatal incidents. During the revision, in addition to damage to the aortic and mitral valves of the heart, metastatic masses grew into the layer of the myocardium, the removal of which is technically impossible.In the early postoperative period, the patient died due to embolization into the brain and coronary arteries. Diagnosis of Ewing’s sarcoma requires timely diagnosis and treatment in order to prevent the rapid spread and development of life-threatening and fatal complications.

Figures of consolidated statements of cash flows of the world's leading publicly traded oil and gas corporations
Authors: SHIMKO Oleg V.
Published: May 2022

Subject. The article considers the main figures of consolidated cash flow statements of twenty five leading publicly traded oil and gas companies from 2006 through 2018.
Objectives. The purpose is to determine the current values of the main components of the said consolidated cash flow statements, to identify key trends in their changes during the study period, to establish the factors that led to the changes.
Methods. The study draws on methods of comparative and financial-economic analysis, generalization of materials of consolidated income statements.
Results. The paper determines dynamics of changes in the value of key indicators and their correlation in the structure of cash flow statements in the stock market sector of the industry, establishes the main factors that contributed to the transformation, based on the results of a comprehensive analysis of annual reports of 25 oil and gas companies. It shows an increase in cash from operating activities within the studied period; the dynamics of the indicator is quite consistent with the change in average annual oil prices, despite the integrated business structure of most companies; capital expenditures of companies also depend on the level of oil quotations with a general upward trend. The analysis demonstrated that the exploration and production sector often dominates in the structure of capital expenditures, even for integrated corporations. Free cash flow returned to its previous level after a fall during the global financial crisis, only when corporations at the height of the industry crisis were able to reduce capital expenditures, which increased during a favorable period. I also revealed a growth in dividend payments, which outperformed the free cash flow most of the time. This contributed to the debt burden growth.
Conclusions. The stock market segment of the industry is characterized by the need to limit capital expenditures in order to maintain the free cash flow of companies.

When Building a Blue Footbridge – Construction Challenges
Authors: Arason Magnús , Óskarsson Kristján Uni , Gunnarsson Andri , Krommen Terje
Published: May 2022

2019 saw the completion of a road upgrade project in the town of Mo i Rana in Nordland county in Norway. The project, owned by the Norwegian Public Road Administration, had the objective of a safer and more efficient daily commute for students at the Arctic Circle High School. This is achieved by providing improved links to bus routes along the busy Fv810 main road, not least by constructing a footbridge over the road. EFLA Consulting Engineers carried out the bridge design. A preliminary design phase resulted in the chosen bridge being a 106-m long steel girder bridge in six spans. The very effective 3-m wide cross section consists of a 610-mm diameter steel tube as the primary member, supporting an orthotropic stiffened deck plate and stainless-steel edge girders. Variable depth to bedrock along the bridge length led to different foundation designs for the bridge supports, with four of the seven bridge axes being founded on piles and the rest directly on bedrock. Following an open tender and contractor selection process, the bridge construction works started in October 2018. The construction process saw some significant challenges, which are reported in the paper. These included a re-design of one of the end abutment foundations due to an unexpected bedrock profile, and the late discovery of substantial welding deformations of the longest bridge span element, which had to be remedied by an in-situ temperature treatment. Handling these challenges presented an interesting learning experience for the bridge owner, the design team and the contractor.
A Family of Bridges in Riedlingen
Authors: Sander Christiane , Behrmann Tilo , Plieninger Sven
Published: May 2022

In Riedlingen/Danube (Germany), extensive flood protection measures had to be implemented in recent years, with the result that many of the existing bridges had to be replaced. The bridges are very important for Riedlingen, as they provide access to the historic town center. The opportunity was used to develop an urban design concept with an interdisciplinary planning team. The entrances to the old town were enhanced with their own sojourn quality. As a result, three new bridges were built and another one is currently under construction.

It is a rare opportunity and special task to design several bridges that are within a few hundred meters of each other. It is important to ensure not only that the structures are integrated into their respective environments, but also that there is an appropriate hierarchy among them. For the bridges in Riedlingen, the aim was to create modern, elegant structures that complemented their historical or near-natural surroundings. At the same time, they were to set a high architectural standard that had the potential to act as a catalyst for future redevelopment areas in the city. The associated lighting – as an important component of the public space, which has been proven to contribute to its identity and safety – was also commissioned as part of the planning services and integrated into the structures from the very beginning.
Opening the Cage
Authors: Marks James
Published: May 2022

American cities can tend to lag behind Europe both in their continued reliance on the car as a primary means of urban transportation, and in the realisation that civic structures such as footbridges can successfully create new urban landmarks. In a political environment which tends to favour utilitarian caged bridges for pedestrians over more elegant and expressive structures, this paper will describe the solutions adopted by an integrated international design team to eschew mundane standard US bridging solutions in favour of a visually exciting structure that is intrinsically expressive of its unique urban context. Prepared by the bridge architect, the paper will concentrate on visual and spatial aspects of the proposals as opposed to technical engineering detail.

Weaving below an adjacent rail viaduct and above the Mystic River in northern Boston MA, the footbridge will provide a link between the communities of Everett and Somerville as part of an evolving commuter cycle network. The whole crossing has been conceived as an open and inviting environment - an unfolding pedestrian experience with ever-changing vistas. Design work was started in 2017 with the 75% design stage reached in mid-2019. The bridge was granted funding in October 2021 and at the point of writing this paper, construction is slated to commence by 2023.
Footbridge in History
Authors: Siviero Enzo
Published: May 2022

The aim of this paper is to present some historical bridges that explain the importance of these works of art in terms of culture, as part of a broader context of landscape and meaning. They are pedestrian bridges that cross through places and time, each of which expresses its own genius loci through the history and events that have involved them. The bridge, in fact, should not be considered as simply an object characterized by its own formal image, the result of consolidated construction technology; instead, it becomes part of the very context in which it stands when it embraces the meaning, history and tangible and intangible components of the place. This is why the paper will describe various footbridges that in different ways each express a strong tie with the history and the meaning of their location and the surrounding landscape. From the Pont du Gard, the ancient Roman aqueduct included on the World Heritage List, now able to be crossed at the various levels and part of a huge UNESCO-protected nature and archaeological park, to the Mediaeval bridges of the devil, the symbols and legend of the location in which they stand; or indeed the Mostar Bridge, representing the rejoining of the banks after destruction at war; the Istanbul aqueducts, offering the opportunity of requalifying the place and giving rise to new landscape offerings; or finally, the Venice Calatrava Bridge, an emblematic example of the contrast of the old and the new, expressing the conflict that can be generated by the inclusion of a new architecture into a historic context bursting with meanings.
The New Mill-Bridge in Besigheim, Germany
Authors: Keil Andreas , Linden Sebastian , Sander Christiane
Published: May 2022

In the small village of Besigheim, north of Stuttgart, a footbridge over the river Enz was built just in front of the historic, listed cityscape.

With a curved span of approximately 70m and inclined hanger cables just connected to the outer edge of the superstructure, the one-sided suspension bridge offers pedestrians a direct connection from the new-built park and garage to the medieval city-center, and cyclists to smoothly transfer from one river bank to the other.

The new footbridge, despite being a highly technical lightweight structure, respectfully considers the local context and carefully embraces the adjacent listed water mill. It hence contributes in form and function to the creation of the new park and playground at the riverbank, and it allows visitors for a new experience of the river and the historic cityscape.
The Cable Net Bridge

Published: May 2022

This paper comprises a preliminary footbridge design concept, intended for the quay areas of Tønsberg and Kaldnes, in Vestfold, Norway. With an engineering approach, the paper investigates the usefulness of a cable-net concept using tension membrane technology, and includes simplified design analysis and natural frequency controls. The aim of the project is to create a bridge concept with a stable and light structure, as well as serve the city inhabitants a positive tectonic experience. The paper reports on its contextual background, inspirational sources, and present some structural outputs of the bridges superstructure.

The bridge concept involves a 200-meter-long and 12-meter-wide cable-net bridge, with a 6-meter-wide timber grid shell on top, as the pedestrian footpath. This is a quite novel concept, tension bridges usually use tall towers to hang the structure. This paper study the cable-net concept, and some structural concerns on the cable-net and and a timber grid. Other relevant issues such as a bascule tilt function, or design of substructure are not addressed in this paper. The project concludes this bridge concept to have some potential, but deemed unsuitable for the canal area in Tønsberg... The bridge deck is of academic interest, and deserve further exploration. Yet, the public of Tønsberg request for a bascule bridge with tilt function. The canal offer nothing but poor ground and anchorage conditions. Hence, this outlined cable-net bridge become impractical and overly complicated to its addressed location. On the other hand, for urban areas with accessible rock footings, this bridge concept may be ideal.

Published: May 2022

‘Varvsbron’, a pedestrian and cycle bridge; and a key part of ambitious plans to revitalise the city of Helsingborg, connects the main Public Transport hub, across the ferry link to Denmark and the existing harbour, to a new urban development of the docks called Oceanhamnen.

This paper charts the development of the bridge’s design, an innovative cable-stayed/suspension hybrid, with input from the bridge’s architect and the engineering team responsible for design development and detail design.

It will focus on how the team’s innovative use of parametric modelling software simultaneously confirmed the final aesthetic form, addressed complex structural and buildability issues, and ultimately made this distinctive bridge both structurally efficient and buildable.

The bridge posed challenges in terms of planning and execution, which were successfully overcome by world class engineering, skilled project management and efficient collaboration between all those involved.
Footbridges over Varbitza River – the only Link Between Remote Villages and the Railway

Published: May 2022

This article reviews the service condition of three pedestrian suspension bridges. They are located in the Rodopi mountains, outside urbanized area. These bridges are crossing Varbitza river at different locations along its length and are mainly used by the locals in order to access the railway line (stations) running along the river. All bridges are suspension bridges with main span varying from 120m to 260m. Originally they were built more than 50-60 years ago. Reconstruction of their superstructures took place 10 to 15 years ago. Visual inspection, made in the summer of 2021, reviews their service condition, which is further discussed in this article.
Campusbrücke Opladen - Applying Sustainable Design Strategies within Changing Constraints
Authors: Halaczek Bartlomiej , Knight Martin
Published: May 2022

Footbridges facilitate pedestrian and cyclist travel which can promote a shift towards greener means of transportation and thus help reducing carbon emissions. Facing the challenges of climate change, further steps in the reduction of waste and carbon footprint must be taken, by addressing the structure and construction method itself.

The Campus Bridge in Opladen, Germany, is a 100m long footbridge crossing a major multi-track rail corridor. The bridge, and its equally long access ramps, was developed following a selection of approaches recommended to reduce its impact on the environment. This includes easily recyclable weathering steel, clamped and bolted architectural fit-out elements, the intensive use of habitat-friendly gabion walls as an alternative to concrete retaining walls, and the preference of lansdscaped embankments to elevated access ramps. The bridge was built in a temporary condition in 2013, awaiting the urban developments on both ends to catch up, including the removal of a two-track rail corridor requiring a temporary extension of the bridge and a temporary access ramp. For the final set-up between 2018 and 2021 elements of the temporary ramp have been re-used for the final ramp and one bridge span has been re-adjusted to accommodate the new, shorter gradient. The paper will provide a case study discussing how the re-use of building components can be integrated in the design process to respond to varying constraints in order to reduce waste and save cost.
Re:crete – a Footbridge Made of Reused Concrete Blocks

Published: May 2022

Today, concrete is the most widely used construction material worldwide. Strong, versatile, durable, and vector of economic development, this exceptional material is also the principal cause of greenhouse-gas emissions, material depletion and waste generation by the construction industry. Hence, reusing concrete elements extracted from obsolete building structures has large potential to significantly reduce the environmental impact of construction. To demonstrate the potential of such an unusual strategy for bridge construction, this paper shows the construction of the Re:Crete arch prototype. It is made of 25 reclaimed concrete blocks connected through post-tensioning to create a 10-m span arch. The complete design-and-build workflow of the prototype is presented, including the structural design of the arch, the sourcing of the reusable concrete elements and the assembly. The Re:Crete arch prototype mechanical properties and environmental impact are assessed through non-destructive investigation, load testing and Life-Cycle Assessment. The results show that the reuse of concrete blocks leads to a comparable structural behaviour as a similar arch made of new or recycled concrete, with an environmental footprint reduced by more than 70%.
Esperance Bridge – An Innovative Take on a Truss Bridge
Authors: Wilson Ian , Hooton Martin , Fercocq Solene , Addy Ben , Groskin Ezra
Published: May 2022

The Esperance Bridge crosses the Regents Canal in Central London and was opened in the summer of 2021. It is an innovative take on a traditional warren truss bridge that uses tapering and folded steel plates to create an elegant and sculptural form at this popular section of the canal. The bold pomegranate red carbon steel plates set against the diagonal stainless steel tension ties illustrate the structural behaviour of the Warren truss, where struts act in either compression or tension.

The bridge is the final of three canal crossings in the heart of the landmark Kings Cross Development, developed by Argent. The bridge completes a new pedestrian route through the development and crucially provides greater connectivity to the shopping destinations at Coal Drops Yard. The pedestrian bridge compliments the Victorian heritage of the canal environment while providing a viewing platform and enclosure to the adjacent Ghat Steps, which is a popular public event and leisure space.

In addressing the conference themes, the paper focuses on the user experience and how the context of the bridge fits within a wider pedestrian network. The design, fabrication and construction of the bridge is also discussed.
Exploring Concepts For UHPFRC Bending-Active Footbridges
Authors: Lázaro Carlos , Castro-Bugallo Carmen , Navarro-Gregori Juan , Serna Pedro
Published: May 2022

This contribution describes two concepts for lightweight bending-active footbridges, and the corresponding experimental prototypes made of ultra-high-performance concrete (UHPFRC). The first prototype (bending- active bow-string concept) has a span length of 5.4 m and is composed of a thin UHPFRC prestressed slab, a UHPFRC deviator and stainless-steel tensioning cables. The second prototype (bending-active lenticular beam concept) has a span length of 6.2 m and is composed of two lateral lenticular beams and thin deck plates, all made of UHPFRC elements. In both prototypes, the upper structural members (the deck in the first one and the top chords of the lenticular beams in the second one) have been bent in the longitudinal direction to achieve the desired structural configuration. This kind of structure is referred to as bending-active in the literature; it combines the advantages of easy manufacturing (flat components) and lightweight (thin members) with an increased stiffness through the final curved geometry achieved through bending. The prototypes take advantage of the capacity of UHPFRC to resist traction and bending with microcracking in service conditions. To the authors’ knowledge, these experimental footbridges are the first application of UHPFRC for bending-active structural members, demonstrating the possibility to use this material as an alternative to timber or FRP.
Physical and Psychological Factors Influencing the Acceptance of Vibrations on Lightweight Footbridges
Authors: Stasica Maximilian A. , Frankenstein Julia , Schwinn Gregor , Zhao Guoping , Seyfarth André
Published: May 2022

Especially lightweight and long-span footbridges are prone to vibrations and oscillations induced by users or environmental factors. While the interaction between construction, structure, stability and resulting vibrations have been investigated thoroughly in the past, research assessing user experience remains sparse.

In this paper, we discuss which factors may influence user’s acceptance of footbridges. We propose a taxonomy consisting of properties of the bridge construction, the environmental situation and human and psychological factors. Psychological factors like emotional states (i.e., varying psychological status like e.g., fear of heights, stress), cognitive factors (e.g., knowledge, reasoning and cognitive control of emotions) and personality traits (i.e., quite constant characteristics of the user’s personality) are discussed with their potential to influence user’s acceptance of footbridges.

In our paper, we present the possible interplay of those bridge factors, environmental factors and human factors. Our taxonomy will help to improve footbridge design with respect to user’s experience and acceptance.
A Setup for Assessing the Acceptance of Vibrations to Improve Footbridge Design

Published: May 2022

Comfort and acceptance are vital to user experience and therefore one of the main challenges in footbridge design. Due to the community’s current thrive towards efficient lightweight footbridges, pedestrian induced vibrations come into focus. This implies the need for empirical investigations of user experience on vibrating footbridges.

In this paper, we present a setup that is simulating a vibrating surface. It consists of a movable platform coupled with a virtual reality based head mounted display to emulate varying bridge features (e.g. different heights, widths, surroundings). The user facing a bridge in the virtual environment experiences vibrations that are similar to those pedestrians induce on lightweight footbridges. These are mirrored in real-time in the virtual environment. As we combine this setup with additional biomechanical measurement equipment (Motion Capture, Ground Reaction Force Plates, and Electromyography) we obtain a comprehensive picture of the user’s physical response towards the respective bridge features.

Our setup therefore yields the opportunity to further investigate the influence of vibrations and bridge features on the physical response of a user. The setup described can be used by researchers and bridge designers to assess and further enhance user experience on modern lightweight footbridges.

Batu saluran kemih (BSK) atau urolithiasis adalah suatu kondisi patologis yang ditandai dengan keberadaan batu di traktus urinarius. Di Indonesia, BSK merupakan salah satu dari tiga penyakit yang terbanyak di bidang urologi. Umumnya pasien BSK mengeluhkan nyeri pada pinggang. Untuk menegakkan diagnosis dapat dilakukan pemeriksaan lanjutan seperti pemeriksaan radiologi dengan menggunakan CT-Scan yang dapat memberikan hasil pencitraan yang lebih baik dibandingkan foto konvensional dan ultrasonografi. Selain dapat menentukan ukuran dan letak dari batu, CT-Scan juga dapat mengukur kepadatan dari batu dengan Hounsfield Unit (HU). Hounsfield Unit juga telah digunakan untuk menentukan komposisi dan opasitas dari batu saat dilakukan diagnosis. Penelitian ini bertujuan untuk menilai hubungan kepadatan batu menurut HU dengan komposisi batu saluran kemih di poli urologi RSUD Abdul Wahab Sjahranie Samarinda. Penelitian dengan metode cross sectional dilakukan pada 30 pasien BSK. Analisis data menggunakan uji Mann-Whitney. Hasil uji Mann-Whitney atar menemukan kelompok yang memiliki hubungan adalah kalsium oksalat-asam urat (p=0.000) dan asam urat-struvit (p=0.013), sedangkan kelompok kalsium oksalat-struvit tidak memiliki hubungan (p=0.132).
