AbstractHeart diseases remain the top threat to human health, and the treatment of heart diseases changes with each passing day. Convincing evidence shows that three-dimensional (3D) printing allows for a more precise understanding of the complex anatomy associated with various heart diseases. In addition, 3D-printed models of cardiac diseases may serve as effective educational tools and for hands-on simulation of surgical interventions. We introduce examples of the clinical applications of different types of 3D printing based on specific cases and clinical application scenarios of 3D printing in treating heart diseases. We also discuss the limitations and clinically unmet needs of 3D printing in this context.

The purpose of the study was to investigate the method of osteosynthesis using glues. Materials and methods. The simplest and most effective method in the treatment of traumatological patients is a plaster fixing bandage of different variations. This is a conservative type of treatment. Also, a very common method in the treatment of orthopedic and traumatological patients is the surgical method. Modern high-tech methods of osteosynthesis require a thorough preoperative examination of the patient, conducting a 3D tomographic examination for intra-articular fractures, clear planning of the course of surgical intervention, electro optical probing techniques during the operation, the availability of tool kits for installing retainers, the ability to choose a retainer intraoperative in the size range. An orthopedic-traumatologist and the entire operating team need appropriate training. All operational fixation methods must provide adequate stability to maintain axis length and rotation. Results and discussion. In the world practice, biological glues are used in such areas as abdominal surgery, neuro- and cardiac surgery, plastic and pediatric surgery, orthopedics and traumatology. Cyanocrylate glues have undergone extensive experimental clinical testing. Positive characteristics of cyanoacrylate glues are the ability to glue living tissues in a humid environment, polymerization rate, autosterility, bactericidal, absence of histotoxicity, hemostatic effect. Another glue in the review is sulfacrylate. It can be used in patients of any age, starting from newborns, regardless of the pathogenesis of the disease. Venaseal glue, used by many authors to treat fistulas of the gastrointestinal tract. Widely used fibrin glues, such as Evicel, are used to achieve hemostasis and sealing in surgery, for example, in vascular operations, kidney resection and neurosurgical interventions, in the surgical treatment of distal hypospadias in children. BioGlue glue is designed to seal surgical sutures, thereby preventing fluids (exudate, lymph, urine, gastric juice) and / or air from leaking through them. It is also used in liver surgery. At the moment, the use of bone cement is the most common auxiliary method for surgical interventions. But its side effects are very clear. Bone cement can cause the patient to die on the operating table or, in the postoperative period, in intensive care. This is due to an immediate or rapid allergic reaction. This situation is dangerous for humans. Biological glues are not so toxic and do not cause such allergic reactions Conclusion. The search for new materials and techniques for consolidating bone fragments is one of the most important problems of modern medical science, namely orthopedics and traumatology. Substances that are included in the biological glue must be bioinert, contain elements of strength (for holding fragments), looseness of the structure (for germination of capillaries between fragments), natural antibiotic (for antibiotic prevention), activators of hematopoiesis processes (for the fastest callus), organic and inorganic substances (for the building material of bone tissue). Therefore, the desire to improve treatment and improve its results, in particular in orthopedics and traumatology, is the key to the development of modern medicine

It is problematic to apply traditional microtechnologies for the manufacturing three-dimensional (3D) components of microsystems due to a number of inherent disadvantages. It is much more promising to use additive technologies for these purposes. In present paper various additive technologies used for manufacturing non-electronic components of microsystems as well as various non-electronic components manufactured using these technologies are considered. The peculiarities of the implementation of additive technologies in the manufacture of non-electronic microcomponents are discussed. More than 20 types of additive technologies characterized by different principles for the implementation of 3D printing processes are presented and their brief description is given. Most of these technologies allow manufacturing the components with micrometer feature sizes and some of them — with nanometer feature sizes. Microcomponents produced by additive technologies are intended for use in micromechanics, microoptics and microfluidics. Many examples of such microcomponents are given with indication of their typical feature sizes. Additive technologies make it possible to create both individual parts of microdevices and completely finished micro-devices. Microcomponents are mainly made from photopolymers and thermoplastics, as well as metals. Among additive technologies those that provide the multi-material 3D printing as well as the embedding of discrete components into printed microdevices are especially promising. It is expected that in near future additive technologies will be widely used in the production of various non-electronic components of microsystems.

New Diagnosis

The evolution of modern medicine, in its continuous developing process, is highly connected with the progress achieved in the medical branch of technology. Regarding the surgical specialties, the technological progress breakthroughs may determine the appearance of new diagnosis techniques, but also shape innovative treatments, leading to superior therapeutic results. In the surgical treatment as a whole, an essential role is played by the Medical Imagistics. They either offer the much-needed visual support in order to reach an accurate diagnosis, or guide the surgeon in choosing a certain type of intervention. The importance of Imagistics is indisputable. It has also been proven so in intraoperatory guidance and monitoring the patient in post-surgery. In the evolution of medical Imagistics, after the transition to digital imaging, followed by graphic 3D reconstructions based on CT and MRI data, we find ourselves contemporary with a new turning point announcing a technological revolution: the transition from virtual 3D models to tangible 3D replica. Since the beginning, the 3D printing technology has been of great importance to the field of medical research and, once the technique gained popularity, it became a modern tool for many medical specialties, in particular for cranio-maxillofacial surgery, orthopedics, oncology, neurosurgery. The 3D printing technology managed to transgress dated barriers by facilitating the manufacturing of implants or implement new treatments in regenerative medicine. The purpose of this original paper is to present our 3D printing work protocol and general conclusions after 5 years of implementing 3D printing in pediatric orthopedics.

The article presents material about the main prospects for the introduction and operation of new additive technology in the Republic of Kazakhstan. Additive technology (3D printing) is a global phenomenon that contributes to the development of new industries that use digital technologies. 3D printing is necessary for the production of quality products. Kazakhstan, the world’s fifteenth largest gold producer, does not actively promote the jewellery industry. Jewellery is an obligatory attribute of a family celebration and an element of the national culture of Kazakhstan. Jewellery products purchased in Kazakhstan are only 10% local; all the rest are from Russia, Turkey and Europe. New production of jewellery products using three-dimensional modelling and additive technologies should become an image industry in Kazakhstan, due to exclusivity and affordable cost

Three-dimensional (3D) printing is a process that translates a 3D virtual model into its physical 3D replica. In medicine, Neurosurgery, Orthopedics and Maxillo-facial surgery were the first specialties to successfully incorporate this technology in their clinical routine, as an aid to surgical interventions. The study aimed to provide a clear overview of the potential areas of applications of 3D printing (3DP) for management of renal diseases, based on a review of the literature. Method. We carried out a review of the literature according to PRISMA recommendations. We searched three databases (Medline, Scopus and Cochrane) with two specific queries: one using MeSH-terms and the second one based on free terms, all terms were related to nephrology and three-dimensional printing technology. Results. 3D-printed models were mostly employed for the management of renal tumors and lithiasis. They provided enhanced visualization of structures and the possibility to perform procedures rehearsals which seemed to improve surgical procedures. Models were also reported to positively impact patients’ understanding of their condition and the interventions. Trainees and experienced urologists also benefited from the supportive role of 3D-printed models and reported improved confidence and efficiency. Rare reports discussed their use for kidney transplantation, ureteropelvic junction obstruction syndrome treatment, nuclear medicine or cultural issues. Due to a meager data amount and heterogeneity of studies, no advanced statistical analysis was possible. Conclusion. 3D-printed models of renal anatomical structures are feasible and are valuable tools to support renal disease management, and for educational purposes.
