Modern traumatology is characterized by high energy trauma, simultaneously affecting parts of the body especially in young patients. One of the most severe aspects resulting of high energy trauma is that of multiple skeletal injuries, with bone loss, which require complex treatment; this refers both to methods of filling the bone defects and to interdisciplinary approach whenever soft tissues are injured, as well. This case demonstrate the impact of modern approach in high energy trauma, with multiple aspects: bone substitutes as effective technique of bone filling and prevention of septic complications, as well as team work for concomitant treatment of associated injuries. The outcome of the patient, compared to the initial status, demonstrate the benefit of bone substitutes for a rapid recovery of trauma patients, with major impact on social and professional recovery.

A promising approach for the development of sustainable and resource-saving alternatives to conventional material solutions in vehicle structures is the use of renewable raw materials. One group of materials that has particular potential for this application is wood. The specific material properties of wood in the longitudinal fiber direction are comparable to typical construction materials such as steel or aluminum. Due to its comparatively low density, there is a very high lightweight construction potential especially for bending load cases. Structural components of the vehicle body are exposed to very high mechanical loads in the case of crash impact. Depending on the component under consideration, energy has to be absorbed and the structural integrity of the body has to be ensured in order to protect the occupants. The use of natural materials such as wood poses particular challenges for such applications. The material characteristics of wood are dispersed, and depend on environmental factors such as humidity. The aim of the following considerations was to develop a material system to ensure the functional reliability of the component. The test boundary conditions for validation also play a key role in this context. The potential of wood–steel hybrid design based on laminated veneer lumber and steel was investigated for use in a component subjected to crash loads such as the door impact beam. The chosen solution involves a separation of functions. A laminated veneer lumber-based beam was hybridized with a steel strip on the tension side. The steel strip was designed to compensate the comparatively low elongation at fracture of the wood and to ensure the integrity of the beam. The wooden component was designed for high energy absorption due to delamination and controlled failure during the impact, while maintaining the surface moment of inertia, i.e. the bending stiffness of the entire component. This approach was chosen to ensure the functional safety of the component, avoid sudden component failure and utilize the high potential of both materials. The tests carried out provided initial functional proof of the chosen solution. The hybridization achieved significantly higher deformations without sudden failure of the beam. In addition, bending capabilities were increased significantly compared to a beam without hybridization. In comparison with a state-of-the-art steel beam, the hybrid beam was not able to achieve the maximum deformation and the target weight of the hybrid beam. Further optimization of the hybrid beam is therefore necessary.

Background. Psoriasis is a chronic, inflammatory, and multifactorial dermatosis that impairs quality of life (QoL). Health-related QoL has become an important element in medical decision-making along with the effectiveness and the harmlessness of the treatments. Objective. To assess the impact of psoriasis in the QoL of patients with psoriasis by using the DLQI scales. Methods. A cross-sectional study from January to June 2018 was conducted in the Department of Dermatology of the University Hospital Joseph Raseta Befelatanana, Antananarivo, Madagascar, including patients more than 18 years old with mild to severe psoriasis. The severity of psoriasis was assessed using the “Psoriasis Area and Severity Index (PASI)”. QoL of patients with psoriasis was evaluated by using the DLQI scales. Results. 80 patients were included, their mean age was 36.5 years, and the male to female was 1.5 : 1. The mean DLQI score was 13.8. Symptoms, feelings, and psychic were the most altered dimensions. QoL was impaired in young patients, single, having medium level education. Even though patients with disease duration more than 5 years had higher DLQI score than other patients, the difference was not statistically significant (p=0.36). Furthermore, the clinical presentation of psoriasis did not influence the patient’s QoL (p=0.73). Patients with nail involvement had QoL impaired but the difference with another localization was not statistically significant (p=0.2). The quality of life was influenced by body area involved. The higher the body surface area involved, the more QoL is impaired (p=0.002). Furthermore, the higher the PASI, the more QoL is altered (p=0.002). Conclusion. Psoriasis has a negative impact in the quality of life in Malagasy patients with psoriasis, especially in younger and single patients. Worse quality of life is correlated to severity of psoriasis.

The knee is one of the main load-bearing joints of the body, and injuries to it can involve damage to the joint or articular surfaces, or fractures to the long bones in case of high-energy trauma. The position of the contralateral leg can cause difficulty in positioning for imaging, but good positioning and technique should allow demonstration of the region for intervention. This chapter covers a selection of orthopaedic procedures involving the distal femur and knee, covering distal femoral plating and LISS plates, tension band wiring of the patella, and cerclage wiring of the patella. Each procedure includes images that demonstrate the position of the C-arm, patient, and surgical equipment, with accompanying radiographs demonstrating the resulting images.

Concomitant ipsilateral femoral neck and shaft fractures are uncommon, occurring in 1-9% of femoral shaft fractures. While this injury typically occurs in young patients following high-energy trauma, little consensus has been established regarding the optimal fixation approach. A multitude of treatment strategies exist, with limited evidence as to which is more favorable. The aim of this study was to appraise current evidence, comparing management with either one single or separate devices for both fractures. A systematic review was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies published between 1992 and 2018 comparing the rate of postoperative nonunion, malunion, delayed union, avascular necrosis, infection or reoperation between at least one method of single device fixation and one method of separate device fixation were included. Six non-randomized cohort studies assessing 173 patients were suitable for inclusion, each comparing single device cephalomedullary nail fixation of both fractures with a combination of devices. All patients presented following high-energy trauma, at a median age of 32 years. While low complication rate and favorable outcomes were found across both groups, no significant difference could be inferred between either treatment strategy. This injury continues to occur in the traditionally described patient group, and results in acceptable postoperative outcomes. A paucity of randomized studies limits the ability to recommend a single or separate device treatment approach, and as such prospective, randomized trials with adequately powered sample sizes are required to definitively compare surgical management strategies in this rare but complex injury.

A traumatic infra-renal aortic dissection is a rare but life-threatening injury that follows deceleration injuries. The mechanism of blunt abdominal aortic injury involves both direct and indirect forces. The successful management of patients with traumatic injuries depends on a prompt suspicion of the injury and early diagnosis and therapy. Missed injuries in trauma patients are well-described phenomena and implementation of the ATLS® trauma schedule led to a decrease in the number of missed injuries, but trauma computed tomography (CT) scans in injured patients are still not standard. We report on a 54-year old Caucasian female patient who was involved in a car accident. The fellow passenger of the car was seriously injured. The patient had been previously treated at two different hospitals, and a dislocated acetabular fracture had been diagnosed. Because of this injury, the patient was transferred to our institution, a level 1 trauma-center where, according to the nature of the accident as a high-energy trauma, a complete polytrauma management was performed at the time of admission. During the body check, a moderate tension of the lower parts of the abdomen was detected. During the CT scan, an aneurysm of the infra-renal aorta with a dissection from the height of the second lumbar vertebral body to the iliac artery was observed. The patient required an operation on the day of admission. After 19 days post-trauma care the patient was able to leave our hospital in good general condition. Therefore, missed injuries in multiple injury patients could be fatal, and it is essential that the orthopedic surgeon leaves room for suspicion of injuries based on the nature of the trauma. Traumatic injuries of the abdominal aorta are rare. According to the ATLS® trauma schedule, all of the patients who have experienced high-energy trauma and associated fractures should undergo routine screening using a trauma CT scan with contrast agents to detect potential life-threatening injuries. In case of abdominal trauma, an aortic dissection, which can easily be overlooked, has to be considered.

Due to the rapid development of feed since the early 1990's, efficiency has increased dramatically. The effectiveness is achieved by increasing energy levels, reducing the level of carbohydrates and balancing various nutrients that meet the needs of fish. Improvement of efficiency should be taken into account when determining the amount of ration feeding. The economic efficiency of growing fish depends largely on proper feeding. The feed should be dosed depending on its formulation and size, the physiological state of the fish, the temperature of water and the content of oxygen in it. Salmon fish are demanding oxygen treatment. The content of oxygen in water should be at least 7 mg/l. At a lower oxygen level, the growth of fish is suppressed, and the effectiveness of food is reduced. The optimum temperature of water for growing salmon fish is 14–18 °С. Excessive feeding leads to unproductive feed costs and water pollution, insufficient  feeding leads to incomplete realization of potential opportunities for the rate of growth of fish. The quantity of the daily ration is established taking into account the temperature of water and the mass of fish. Depending on their state, activity and conditions of maintenance, it can fluctuate within ± 20% of the norm. In addition, high fertility densities, unsanitary conditions, illness, low water exchange rates, low oxygen content in water affect the efficiency of feeding in trout farms. Due to the fact that the cost of forage for trout is up to 60% of all costs for its cultivation, the problem of it rational use and saving is at the forefront. When feeding trout it is necessary to take into account that the size of granules for young fish in the length of 4–20 cm should be from 2.2 to 2.6% of the body length (according to Smith), which corresponds to the size of the mouth and the distance between the gill stamens in rainbow trout. Fish is best fed often in small portions. The smaller the fish, the more often feeding. Going on a feed of another size or type should be gradually over 3–5 days. If necessary, it is necessary to use special therapeutic granulated food or a mixture of therapeutic ingredients to add to the wet granules. It is necessary to create optimal conditions for growing and to carry out constant monitoring of water temperature and its fluctuations, oxygen content in water, pH, atmospheric pressure, etc. It is necessary to follow the rules of storage of forages, taking into account that the quality of feed after being stored for more than 3 months is deteriorating. This happens. It may be caused by poor water quality or disease. In order for the fish to get used to a particular feeding regime, it is recommended to do feed it at the same time. Today, the diversity of feeds allows you to get a better feed rate, fast growth and a minimal impact on the environment under different conditions, since the need of  fish in nutrients is fully covered by feeds (energy, protein, minerals and vitamins). The use of Aller Aqua feed guarantees receiving of a strong, healthy fish, thus providing good economic performance to farms. The basis of the research is the analysis of the nutritional value of the feeds of the company Aquafeed Fishsfutter of the German producer and Aller Aqua of the Danish company in the production conditions on the farm of the Western Fish Company PP of Peremyshlyany district, Lviv region. Also we should study fodder, their composition and carry out an objective assessment. It is known that fodder of foreign producers are characterized by higher energy value due to increased fat content, which is achieved by application of the appropriate technology and equipment for vacuum desiccation. For example, Aller Aqua's salmon-based compound feed for protein levels 40–46% contains 15 to 32% lipids and 23–24 MJ/kg of gross energy. Due to the high energy value, these feeds allow to provide the growth of fish at low feed costs. The aim of the work was to analyze the impact of different producers of feed fodder for commodity groups of trout on their growth and the development and receipt of quality commodity products in short terms.

ABSTRACT Objectives: The objectives of this presentation are to analyze the kinematics that causes this association, describe the impact of the injury, and evaluate the treatment performed Methods: Three cases are analyzed by quantifying the displacement and angulation of the sternum, the characteristics of the spinal injury and deformity, treatment, and complications Results: The mechanism that causes the injury is flexion-distraction, the component of the vertebral body presented is type A, and the most affected region was T5. Two patients had neurological picture E. Sternum injury was caused by direct trauma Conclusion: The association of these was observed in patients who have suffered from high-energy trauma in a car accident. There was no relationship between the angulation of the sternum and its displacement to the degree of kyphosis and displacement of the thoracic spine. It is important to carry out good radiographic studies that include the sternum when there is suspicion of this relationship.

The human brain weighs approximately 2% of the body; however, it consumes about 20% of a person’s total energy intake. Cellular bioenergetics in the central nervous system involves a delicate balance between biochemical processes engaged in energy conversion and those responsible for respiration. Neurons have high energy demands, which rely on metabolic coupling with glia, such as with oligodendrocytes and astrocytes. It has been well established that astrocytes recycle and transport glutamine to neurons to make the essential neurotransmitters, glutamate and GABA, as well as shuttle lactate to support energy synthesis in neurons. However, the metabolic role of oligodendrocytes in the central nervous system is less clear. In this review, we discuss the energetic demands of oligodendrocytes in their survival and maturation, the impact of altered oligodendrocyte energetics on disease pathology, and the role of energetic metabolites, taurine, creatine, N-acetylaspartate, and biotin, in regulating oligodendrocyte function.

Ayurvedic science is being popularized worldwide. It has established history for the management of Bhagna in Sushruta Samhita. Ayurvedic philosophy is specific pertaining to the body constitution. The human body is composed of Dhatus. “Asthi” Dhatu is one of the main Dhatu in human body. “Asthi” is hard substance which remains even after most part of body has been decayed. Ayurvedic science has established history of trauma to Asthi (Asthibhagna). Ayurveda has aimed high for maintaining normal structure and function of deformed bones. It is high time to re-establish it by adopting proper research and methodology. The skeletal injuries are important incidences in human beings and they demand immediate management. The branch of science that deals with deformities of bones is known as Orthopedics, aimed for “maintenance of normal structure and function of deformed bones.” While bones are very strong they can break. Most often, breaks happen because the bone runs into a strong force, also repetitive force like from running can fracture a bone. High energy trauma result in bone fractures whether it is isolated fracture or dislocation. When a person goes through some form of trauma, as car accident or fall, the impact may break or fracture the bone. The bone fracture may be the result of high force impact or a result of certain medical conditions that weaken the bones such as Osteoporosis. Fracture is properly termed pathologic fracture but not trauma.
