Published: December 2024

This study evaluates the significance of blood microRNA (miR-21-5p) levels as a biomarker for the development or progression of cardiovascular diseases after COVID-19. The levels of circulating miR-21-5p in the blood were analyzed in 120 patients with cardiovascular diseases recovering from COVID-19. Based on inclusion and exclusion criteria, six groups of patients were formed with 20 patients in each of them. All patients had previously suffered from COVID-19 required hospital care. The groups were divided by the presence of previously verified coronary heart disease, hypertension, and atherosclerosis, as well as the absence of diagnosed cardiovascular diseases. The patients were also divided into those with worsening of preexisting circulatory system diseases or their onset and those without such diseases. All patients underwent circulatory system examination before and after COVID-19. Statistically significant differences in miR-21-5p levels were revealed when comparing groups with previously verified coronary heart disease with and without worsening, as well as groups without preexisting cardiovascular diseases. No statistically significant differences in cardiovascular diseases progression were identified when comparing patients with previously verified hypertension or atherosclerosis. Therefore, blood miR-21-5p appears to be a promising biomarker for assessing the progression of coronary heart disease, including in patients recovering from COVID-19. This method correlates with clinical observations in patients with coronary heart disease, as well as diagnostic investigation data. Further studies on larger cohorts of patients with cardiovascular diseases and follow-up monitoring of miR-21-5p expression levels may increase the informative value of this biomarker. It could aid in clinical decision-making process and follow-up monitoring of patients with such diseases in order to reduce adverse complications.

Published: December 2024

This article presents the results of a study of the systemic hemostatic action of recombinant Factor VIIa in a rabbit model of heparin-induced coagulopathy and posttraumatic bleeding, compared to the administration of exogenous fibrin monomer. The coagulopathy was induced by a single intravenous injection of unfractionated heparin at a dose of 150 IU/kg 15 minutes before injury. Recombinant Factor VIIa (270 μg/kg) or fibrin monomer (0.25 mg/kg) was used as systemic hemostatic agents. One hour after administrating the agents, a standardized liver injury was inflicted, followed by an assessment of blood loss characteristics. Using rotational thromboelastometry and coagulation tests, animal venous blood was analyzed for coagulation time, alpha angle, clot formation time, maximum clot firmness, clot density at 10 minutes, activated partial thromboplastin time, prothrombin time, thrombin time, and fibrinogen concentration. Pharmacologically induced coagulopathy resulted in shifts to a hypocoagulable profile, associated with severe blood loss (1.9 times, p = 0.028) and high animal mortality (26.1%, p = 0.022) compared to the control group. Preventive administration of fibrin monomer or recombinant Factor VIIa reduced posttraumatic blood loss (by 5.4 times, p 0.001, and by 2.1 times, p = 0.009, respectively), resulting in a decrease in mortality rates. However, the administration of these agents did not correct the hypocoagulable profile as observed in thromboelastometry and coagulation tests. These data demonstrate the hemostatic effect of both agents, with a more pronounced effect after fibrin monomer administration, and suggest potential use of low doses of fibrin monomer in trauma-related hemorrhage. The mechanism of action of fibrin monomer requires further investigation. Therefore, fibrin monomer, a fibrinogen derivative obtained from blood plasma, could be a valuable candidate for managing wound bleeding in addition to recommended systemic hemostatics.
The eukaryotic system in the third update of the interface “Eukaryotic supergroups: Taxonomy/Biotechnology interface”: Formal procedures for rank changes
Authors: Zmitrovich Ivan V. , Perelygin Vladimir V. , Zharikov Mikhail V.
Published: December 2024

The problem of coordinating the ranks of higher eukaryotic taxa was specifically considered by us in the monograph and a recent article. However, we omitted most of the formal descriptions of the proposed taxa in the new rank. The purpose of this article is a formal description of a number of taxa established by us in the monograph “Nomenclature and rank correlation of higher taxa of eukaryotes and subsequent interface updates”. Here we formally described such taxa as Eocorticata regn. nov., Tsaralia regn. nov., Apusomonadea intraregn. nov., Breviatea intraregn. nov., Eochromista superphyl. nov., Zoosporia superphyl. nov., Eurhodophyta div. nov., Proteorhodophyta div. nov., Anaeramoebea phyl. et cl. nov., Calkinsea phyl. nov., Meteora phyl. nov., Syssomonadea phyl. nov., Chlorodendrophytina subdiv. nov., Chloropicophytina subdiv. nov., Dikaryomycotina subdiv. nov., Pedinophytina subdiv. nov., Picocystophytina subdiv. nov., Sanchytriomycotina subdiv. nov., Agaricomycia supercl. nov., Calcarisporiellomycia supercl. nov., Ceratiomyxomycia supercl. nov., Chytridiomycia supercl. nov., Entomophthoromycia supercl. nov., Entorrhizomycia supercl. nov., Kickxellomycia supercl. nov., Mortierellomycia supercl. nov., Mucoromycia supercl. nov., Myxogasteromycia supercl. nov., Monoblepharomycia supercl. nov., Neocallimastigomycia supercl. nov., Saccharomycia supercl. nov., Acytosteliomycetes cl. nov., Liceomycetes cl. nov., Microheliellida cl. nov., Paratrimastigidea cl. nov., Protosporangiomycetes cl. nov., Pycnococcophyceae cl. nov. The main trends of further improvement of the rank structure of the eukaryote tree we see in 1) some multiplication of the supregroups described for the few taxa now located among the Amoebozoans and TSAR, as well as many environmental sequences; 2) further rationalization of the Fungi and Metazoa system using intercalary taxonomic categories (including additional and not prescribed in both nomenclatural codes ones), and 3) further automatization of the ranking procedure and solving the problem of rank estimating for distant “orphan” taxa.

Authors: Prokopyev Dmitriy S. , Levchik Evgeniy Yu. , Vinogradskiy Aleksandr E. , Borzunov Dmitry Yu.
Published: December 2024

BACKGROUND: Topical negative pressure systems are an effective modern technique for treating patients with infected and purulent wounds, including after joint replacement surgeries.
AIM: To assess the efficacy of negative pressure wound therapy (NPWT) systems in surgical debridement of infected periprosthetic wounds during the first stage of revision hip replacement surgery.
MATERIALS AND METHODS: A prospective case study was performed in 96 patients with deep periprosthetic hip joint infections who received treatment between 2015 and 2020. Inclusion criteria: patients with Tsukayama (1996) type I–IV deep periprosthetic infections, with no possibility of implant preservation (80 cases). These patients had a two-stage revision hip replacement surgery. Exclusion criteria: clinical cases with preserved implant components (16 cases). The study included two groups. In the treatment group, NPWT systems were used for surgical debridement of periprosthetic tissues following implant removal, prior to cement spacer placement (15 patients). In the control group, immediate surgical debridement was performed prior to cement spacer placement (65 patients). In the treatment group, if there were uncertainties about the efficacy of surgical debridement of the periprosthetic wound prior to spacer placement, surgical wound debridement was performed and NPWT systems were applied for 48–72 hours. If the wound showed an improvement, a spacer was placed. If the effect was insufficient, surgical debridement was repeated, and an NPWT system was used again. The second stage of revision join replacement surgery was performed after 2–3 months, providing that the infection did not return.
RESULTS: In 67 (83.75%) of 80 patients, postoperative wounds healed by primary intention. Postoperative wounds were initially closed without skin damage in all cases. In the treatment group, the mean Harris hip score was 54.6±12.2 at baseline and 61.5±8.8 two months after surgery (p 0.05). In the control group, the mean Harris hip score was 56.3±14.2 and 62.1±10.9, respectively (p 0.05). Intergroup differences between Harris hip scores at baseline and after surgery were not significant (p 0.05). There were no significant intergroup differences in the frequency of second-stage revision joint replacement surgery: 14 (86.7%) and 54 (83.1%), respectively (p 0.2).
CONCLUSION: NPWT systems are effective in surgical debridement during the first stage of revision hip replacement surgery, following the removal of implant components. In apparently more complex circumstances of wound infection, this technique provides outcomes comparable to those of immediate surgical debridement of periprosthetic wounds with cement spacer placement.

Arthroscopy of the hip joint: literature review
Authors: Gushchina Daria A. , Yeltsin Alexander  G. , Mininkov Dmitry S. , Malakhova Svetlana O. , Ivanov Yaroslav A.
Published: December 2024

As recently as the middle of the 20th century, arthroscope insertion in a ball-and-socket hip joint was thought to be almost impossible. Hip arthroscopy has evolved greatly since then, and its current development rate is closely related to the detection rate of hip joint disorders. Athletes and other young patients with hip joint injuries are increasingly being diagnosed with constantly evolving disorders. Many of these conditions were previously undiagnosed and hence remained untreated. Hip arthroscopy, like any other procedure, has its risks. This procedure is not widely available, as it requires special equipment and extensive training.

Published: December 2024

INTRODUCTION: Spinal osteomyelitis, also known as spondylitis, is characterized by inflammation of the vertebral column structures caused by various factors, such as injuries, autoimmune diseases, and infectious diseases. Bacterial spondylitis, the most severe form of spondylitis, is frequently caused by hematogenous infection spread and can lead to major complications such as neurological disorders, spinal deformities, sepsis, and death. Bacterial spondylitis is more prevalent in patients over the age of 50 with risk factors such as systemic diseases and immunosuppression. The paper discusses the routes of infection transmission, modern diagnosis tools (CT, MRI, bacteriological and genetic methods), and therapeutic approaches with a focus on surgical treatment.
CLINICAL CASE DESCRIPTION: The paper presents a clinical case of bacterial osteomyelitis of the upper thoracic spine in a 65-year-old female patient with a history of infectious nonspecific polyarthritis. The medical history, clinical presentation, and MRI findings are provided. The transmanubrial approach for optimal corpectomy followed by stabilization with a titanium plate is described.
CONCLUSION: Spinal osteomyelitis remains a major concern, necessitating high-quality surgical intervention. Modern diagnosis tools and individualized therapy are expected to decrease the incidence of complications in patients with infectious spinal lesions.

Published: December 2024

INTRODUCTION: Spinal epidural abscess (SEA) is a rare but severe infectious disease, characterized by the accumulation of pus in the epidural space of the spine. This condition may cause spinal cord and spinal root compression, resulting in a persistent neurological deficit or even death in the event of a delayed or incorrect diagnosis. The prevalence of SEA has increased in the recent decade, which is attributed to increased life expectancy, extensive use of invasive procedures, and an increase in risk factors such as diabetes mellitus, obesity, and intravenous drug abuse. SEA is difficult to diagnose because of its non-specific symptoms. However, clinicians’ awareness and early use of magnetic resonance imaging (MRI) allow timely disease detection and therapy initiation.
CLINICAL CASE DESCRIPTION: Patient (55 years old), presented with complaints of weakness in all extremities and neck pain. The medical history started roughly 4 months ago, beginning with strep throat, after which the patient developed increasing weakness in the extremities. Based on the MRI and CT findings, the following diagnosis was made: SEA at the C4–C5 level, causing spinal cord compression. The following procedures were performed: C4 and C5 corporectomy, epidural abscess excision and drainage, and stabilization with a cervical plate and autograft. A significant improvement was observed in the postoperative period, with a notable decrease of neurological deficit at discharge.
CONCLUSION: This case report highlights the need to improve awareness of SEA among healthcare professionals for early diagnosis and treatment initiation, particularly in high-risk patients. Despite advances in treatment, mortality rates and the incidence of neurological complications remain high, necessitating further research to improve treatment strategies and outcomes in SAE patients.

Authors: Prokofev Alexander A. , Sereda Andrey P. , Ryabinin Mikhail V. , Panteleev Alexander N.
Published: December 2024

Despite advances in aseptic, antiseptic, and surgical techniques, the risk of infectious complications persists. Antibiotics have long been used to prevent these complications, particularly during surgeries involving prosthetic materials, implants, or transplants. However, their use prior to minimally invasive surgeries, such as knee arthroscopy, remains controversial. We reviewed international literature to summarize modern approaches to antibiotic prophylaxis in knee arthroscopy, as well as to determine the prospects of improving rational antibiotic prophylaxis regimens during these surgeries. The search was performed in PubMed/MedLine and eLIBRARY databases. The following search terms were used: “antibiotic prophylaxis in knee arthroscopy,” “antibiotic prophylaxis in ACL reconstruction,” “antibiotics in knee arthroscopy,” and “septic arthritis after knee arthroscopy.” The search yielded 567 studies published between 1986 and 2024. Following screening, 57 eligible studies were selected. All studies were conditionally divided into two groups. The first group included studies addressing routine arthroscopy without grafting. The second group included studies addressing infectious complications and antibiotic use during knee arthroscopy, using tendon allografts and autografts, with anterior cruciate ligament repair as an example. The literature review found that there is no consensus on the feasibility of antibiotic prophylaxis in routine knee arthroscopy. There were no significant differences in the incidence of deep infectious complications between groups of patients with and without preoperative antibiotic prophylaxis. During knee arthroscopy with the use of tendon grafts, antibiotic prophylaxis was performed in all identified studies. There are two commonly used regimens: a conventional regimen that exclusively uses intravenous antibiotics and a combination regimen that includes additional graft exposure to vancomycin solution. The incidence of deep infectious complications was considerably lower in the group where antibiotic prophylaxis was supplemented by graft exposure to vancomycin solution.

Published: December 2024

BACKGROUND: Improving ultra-high-molecular-weight polyethylene (UHMW PE) production techniques continues to be a top priority in medical engineering. This is due to the fact that liners are the weakest components of artificial joints, causing the majority of their damage or destruction. Filler reinforcement of UHMW PE improves the durability of UHMW PE products by decreasing the wear rate and coefficient of friction for various friction pairs.
AIM: To assess the effect of ultra-low graphite nanoplate content (0.006–0.307 mass%) on the tribological properties and wear resistance of UHMW PE-based composites.
MATERIALS AND METHODS: UHMW PE synthesized using various technologies was compared to commercial-grade UHMW PE produced by Ticona. The tribological properties were examined using the Nanovea Tribometer, and the wear resistance was assessed according to ISO 15527.
RESULTS: The study identified the range of graphite nanoplate concentrations with the lowest coefficient of friction. The coefficient of friction of UHMW PE without a filler corresponds to that of commercial-grade products GUR 1020 and GUR 1050 of the Chirulen brand, and composites made from it have a lower coefficient of friction. The optimal filler concentration was determined based on tribological and wear test findings.
CONCLUSION: Graphite nanoplates increase wear resistance when exposed to a water-sand suspension.

BACKGROUND: Surgical site infections (SSIs) are one of the most common preventable healthcare-associated infections, with a significant socioeconomic burden. Information technology, particularly clinical decision support systems, has been shown to improve patient safety. However, there have been few publications on the use of these systems for the prevention and treatment of SSIs.
AIM: To develop a multifunctional patient safety information system (PSIS) for the prevention, diagnosis, and treatment of SSIs in traumatic and orthopedic surgery.
MATERIALS AND METHODS: A PSIS for traumatic and orthopedic surgeons was developed and implemented in the N.N. Priorov National Medical Research Center of Traumatology and Orthopedics in late 2023 to early 2024. The PSIS includes two user systems: 1) an analytical and authoring system (PSIS-Manager) for subject matter experts who develop scenarios; 2) a medical system for patient data entry and access to guidelines.
RESULTS: A PSIS prevention scenario was developed based on the guidelines of the National Association of Infectious and Non-Infectious Disease Control Professionals. It includes 11 recommendations for the preoperative stage, 30 for the perioperative and intraoperative stages, 33 for SSI prevention during surgery, and 7 for the postoperative stage. A surgical antibiotic prophylaxis scenario includes 24 recommendations. Decision-making algorithms for the treatment of SSIs are based on the guidelines of the American Academy of Orthopaedic Surgeons (AAOS). Decision-making involves 6 factors providing 264 various clinical scenarios, with 9 decision options.
CONCLUSION: Scenario-based protocols can be used to support decision-making on patient management strategy, as well to control compliance with SSI prevention and treatment guidelines. Further perspectives on PSIS development in terms of SSI diagnosis and treatment include the use of artificial intelligence technologies to aid in the diagnosis of wound infections and the selection of treatment options.

Authors: Sharov Vladislav Andreevich , Vetrile Marchel S. , Kuleshov Alexander A. , Nazarenko Anton G. , Zakharin Vitaly R.
Published: December 2024

Background: Spondylolysis is a frequent cause of pain in the lumbar spine in adolescents and young adults, especially those who practice sports. Spondylolysis most commonly occurs at the L5 vertebrae, and less commonly at the L4 vertebrae. Multilevel spondylolysis is extremely rare. The low frequency of occurrence and, as a consequence, difficulties in diagnosing multilevel spondylolysis are the reason for the lack of a unified approach to the treatment of this pathology. In most cases, conservative measures are sufficient, but if they are ineffective, surgical intervention is indicated. Options of surgical treatment are mainly characterised by the focus on restoring the integrity of the arch and, if possible, preserving motion in the vertebral-motor segment. This article describes the experience of using custom-made implants for surgical treatment of double-level spondylolysis and a brief review of the literature.
Clinical case description: A clinical case of a 16-year-old patient with bilateral spondylolysis of the L4 and L5 vertebrae is presented. The anamnesis, clinical manifestations, and diagnostic features, including radiological methods of examination, are described. The peculiarities of preoperative planning and modelling of individual implants, surgery and immediate results are presented. A brief literature review describes the main options for surgical treatment of multilevel spondylolysis and demonstrates the validity of the use of individual implants in the surgical treatment of this pathology.
Conclusion: Surgical treatment of double-level bilateral spondylolysis with indirect restoration of the integrity of the vertebral arch with preservation of movements in the vertebral-motor segments can be successfully performed using custom-made implants manufactured using additive technologies. A number of advantages of such implants, such as the ability to design the position and shape of implants considering the individual anatomy of patients, as well as the prevention of contact between the elements of the metal structure during movement, make it possible to improve the results of surgical treatment of double-level spondylolysis.
