[Risk factors for venous thromboembolic complications in elderly and senile patients with diabetes mellitus planned for spinal surgery.]

The search for literature sources in domestic and foreign databases showed the absence of works devoted to the study of risk factors for venous thromboembolic events (VTE) in patients of the older age group with diabetes mellitus who are planned to undergo surgical interventions on the spine, which was the impetus for this study. The aim of the study was to study the risk factors for VTE in elderly and senile patients with diabetes mellitus who are scheduled for spinal surgery. A single-center retrospective study included 119 elderly and senile patients (64 men, 55 women, mean age 74,2±6,5 years) who underwent various surgical interventions on the spinal column. According to the binary logistic regression model, the following parameters are statistically significantly associated with the development of VTEC in the studied group of respondents: age of patients over 75 years (p=0,048), HbA1C levels over 7,5% (p=0,007) and D-dimer over 0,5 mg /l FEU (p=0,034), as well as high risk (5 points or more) of VTE according to Caprini scale (p=0,012). In order to reduce the incidence of VTE in elderly and senile patients with diabetes mellitus who are planned to perform surgical interventions on the spine, it is necessary to verify the above clinical and laboratory parameters in the early stages of hospitalization.

[Facet joint distraction as a risk factor for poor clinical outcomes in older patients after anterior cervical discectomy and fusion.]

The search for literature sources in domestic and foreign databases showed the absence of works devoted to the study of the influence of the degree of distraction of the facet joints in elderly and senile patients who underwent anterior cervical discectomy and fusion (ACDF). The purpose of the study was to study the effect of the degree of facet joint distraction on clinical outcomes in patients of the older age group who underwent ACDF. A single-center retrospective study included 47 elderly and senile patients who underwent ACDF for radiculopathy due to degenerative diseases of the cervical spine. A statistically significant correlation was found between the differences in the value of the interfacet distance and the severity of pain in the cervical spine according to VAS (p<0,01). Patients with X-ray semiotics of facet distraction more than 0,55 mm 12 months after the operation were significantly more likely to experience increased pain in the cervical spine according to VAS (p=0,028) and significantly limited daily activities due to pain in the neck NDI (p=0,043). The choice of indications for ACDF in patients of the older age group should be based on a rigorous analysis of facet distraction, cervical sagittal parameters in combination with the functional status of patients.

Comprehensive agrobiological assessment and analysis of genetic relationships of promising walnut varieties of the Nikitsky Botanical Gardens.

Walnut is an important horticultural crop, the production of which ranks second among all nut crops. Despite the significant demand in the domestic market in Russia, the industrial production of walnut fruits in Russia is currently underdeveloped. At the same time, there is a need to update the assortment with new highly productive varieties adapted to local agro-climatic conditions and having high quality nuts that are competitive at the world level. An important issue for the successful implementation of breeding programs is a comprehensive study of the gene pool. In this regard, within the framework of the study, the task was to evaluate promising varieties from the collection of the walnut gene pool of the Nikitsky Botanical Gardens and analyze genetic relationships based on microsatellite genotyping. On the basis of the performed phenotypic assessment, the study sample, which included 31 varieties, was divided into several groups according to the main phenotypic traits, such as frost and drought resistance, the start of the growing season, the ripening period, the weight and type of flowering, the weight of the fruit, and the thickness of the endocarp. Varieties with economically valuable traits that can be recommended as promising as initial parental forms in breeding work for resistance to abiotic stress factors have been identified, as well as varieties with increased productivity and large fruit sizes. Based on the analysis of eight SSR markers (WGA001, WGA376, WGA069, WGA276, WGA009, WGA202, WGA089 and WGA054), an analysis of the level of genetic diversity was performed and genetic relationships were established in the studied sample of varieties. Six (for WGA089) to eleven (for WGA276) alleles per locus have been identified. A total of 70 alleles were identified for the eight DNA markers used, with an average value of 8.75. Analysis of SSR genotyping data using Bayesian analysis established the presence of two main groups of genotypes. Taking into account the fact that all the studied varieties are selections from local seed populations in different regions of the Crimean Peninsula, the revealed level of polymorphism may indirectly reflect the level of genetic diversity of the local walnut populations. Furthermore, the presence of two genetically distant groups indicates the presence of two independently formed pools of the autochthonous gene pool of the species Juglans regia L. on the Crimean Peninsula.

Genetic structure of the population of wild-growing vines of the Utrish Nature Reserve.

Grapes are one of the most common agricultural crops in the world. Currently, the analysis of genotypes directly at the DNA level is considered to be the most accurate method for studying the plant gene pool. The study of wild vines and ancient varieties in various regions of viticulture is an important direction of research in this field. The purpose of this work was to study the population of wild grapes growing on the territory of the Utrish Nature Reserve on the Black Sea coast of Krasnodar Region. The territory of the reserve is of interest as it is a site of ancient settlements, and the environmental conditions are suitable for the growth of wild grapes. During the survey of the territory, 24 samples of wild grapes were found, which were described according to the main morphological characteristics and analyzed by the molecular genetic method. The found vines were genotyped using 15 DNA markers, including nine commonly used for DNA fingerprinting (VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD28, VVMD32, VrZAG62, VrZAG79) and VVIb23, which allows determining hermaphrodite and dioecious vines. Statistical processing of microsatellite loci polymorphism data was carried out using the GenAlEx 6.5 program. The genetic relationships of the studied vines were evaluated using the PAST 2.17c program. The samples were found to be morphologically and genetically polymorphic. The number of alleles identified in the sample varied from 5 to 18 and averaged 8 alleles per locus. Statistical processing of DNA analysis data made it possible to identify two genetically different populations among the wild discovered vines. An assessment of genetic similarity of the found vines with some local varieties of geographically close viticulture regions, rootstocks and representatives of Vitis sylvestris from other territories was made. One of the populations found in the Utrish Nature Reserve is close to a number of V. sylvestris genotypes, the DNA profiles of which are presented in the Vitis International Variety Catalogue.

[Decompression fusion surgery and minimally invasive microsurgical decompression in patients with single-segment lumbar spinal stenosis]. / Sravnitel'nyi analiz rezul'tatov primeneniya metodik dekompressii so stabilizatsiei i minimal'no invazivnoi mikrokhirurgicheskoi dekompressii u patsientov s monosegmentarnym poyasnichnym spinal'nym stenozom.

There are few studies comparing clinical efficacy of decompression/fusion surgery (transforaminal lumbar interbody fusion (TLIF) + transpedicular interbody fusion) and minimally invasive microsurgical decompression (MMD) in patients with single-segment lumbar spinal stenosis. OBJECTIVE: To compare the results of TLIF + transpedicular interbody fusion and MMD in patients with single-segment lumbar spinal stenosis. MATERIAL AND METHODS: A retrospective observational cohort study included medical records of 196 patients (100 (51%) men, 96 (49%) women). Age of patients ranged from 18 to 84 years. Mean postoperative follow-up period was 20.1±6.7 months. Patients were divided into 2 groups: group I (control) included 100 patients who underwent TLIF + transpedicular interbody fusion, group II (study) included 96 patients who underwent MMD. We analyzed pain syndrome and working capacity using visual analogue scale (VAS) and Oswestry Disability Index (ODI), respectively. RESULTS: Analysis of pain syndrome in both groups after 3, 6, 9, 12 and 24 months clearly demonstrated stable relief of pain syndrome (VAS score) in the lower extremities. In group II, VAS score of lower back and leg pain was significantly higher in long-term follow-up period (after 9 months or more) compared to the 1st group (p<0.05). In long-term follow-up period (after 12 months), there was significant decrease in degree of disability (ODI score) in both groups (p<0.001) without between-group differences. We assessed achievement of treatment goal in 12 and 24 months after surgery in both groups. The result was significantly better in the 2nd group. At the same time, some respondents failed to achieve the final clinical goal of treatment in both groups (group I - 8 (12.1%), group II - 2 (3%) patients). CONCLUSION: Analysis of postoperative outcomes in patients with single-segment degenerative lumbar spinal stenosis revealed similar clinical effectiveness of TLIF + transpedicular interbody fusion and MMD regarding decompression quality. However, MMD was associated with less traumatization of paravertebral tissues, blood loss, fewer unwanted phenomena and earlier recovery.

Intramedullary abscesses of the spinal cord are the rarest form of infectious lesions of the central nervous system. We report surgical treatment of a patient with intramedullary cervical abscess caused by L. monocytogenes. Features of this case are absence of primary purulent focus and atypical infectious agent. The patient underwent surgical treatment for intramedullary cervical abscess and subsequent antimicrobial therapy. Subtotal regression of neurological symptoms was noted in early postoperative period. The authors emphasize strict collegial decision-making regarding diagnosis of this disease and choice of optimal treatment strategy.

[Otorhinolaryngological symptoms of tumors of the pharyngeal process of the parotid saliva (clinical case with literature review)]. / Otorinolaringologicheskie simptomy opukholei glotochnogo otrostka okoloushnoi slyunoi zhelezy (klinicheskii sluchai s obzorom literatury).

The parotid gland is the largest salivary gland. Tumors of the salivary gland account for 5% in the structure of oncological morbidity, and up to 80% of tumors affect the large salivary glands with tumor localization in 20% of cases in the pharyngeal process of the parotid salivary gland. The main clinical sign of a tumor of the parotid salivary gland is the presence of a slowly growing mass in the area of the gland. Often, underestimation of the clinical symptoms of salivary gland tumors is the reason for the late diagnosis of this disease and the initial manifestations of the process remain unnoticed for a long time. In order to increase the efficiency of clinical diagnostics of salivary gland tumors, the staff of the Department of Maxillofacial Surgery, Otorhinolaryngology and Topographic Anatomy with Operative Surgery of the Burdenko Voronezh State Medical University studied the clinical and anatomical parallels of changes in the ENT organs in lesions of the pharyngeal process of the parotid salivary gland. Using the previously obtained results of interdisciplinary interaction of otorhinolaryngologists and maxillofacial surgeons made it possible to increase the efficiency of diagnosis and treatment of patients with tumors of the pharyngeal process of the parotid salivary gland.

[Minimally invasive microsurgical decompression in patients with monosegmental lumbar spinal stenosis]. / Rezul'taty primeneniya minimal'no invazivnoi mikrokhirurgicheskoi dekompressii u patsientov s monosegmentarnym poyasnichnym stenozom.

Surgical treatment of degenerative lumbar spinal stenosis is an actual problem of modern spinal surgery and orthopedics. OBJECTIVE: To analyze the results of minimally invasive microsurgical decompression (MI-MD) in patients with monosegmental lumbar spinal stenosis. MATERIAL AND METHODS: A retrospective observational cohort study was performed. We analyzed medical records of patients who underwent MI-MD for monosegmental degenerative lumbar spinal stenosis. Clinical and objective results of MI-MD, as well as the types and prevalence of adverse clinical events were studied. RESULTS: The study included 96 medical records (50 (52%) males and 46 (48%) females aged 18-84 years). Analysis of pain in lower back and lower extremities in 3, 6, 9, 12 and 24 months after MI-MD showed a significant decrease of this indicator (p<0.001). There was significant improvement of capacity according to ODI score up to 5-12% in 72.9% of patients in early postoperative period (p=0.055). In delayed postoperative period, we also observed significant improvement of working capacity according to ODI score and gradual decrease in disability index (p<0.001). Adverse clinical events occurred in 6 (6.2%) patients. CONCLUSION: MI-MD is a highly effective surgical method for monosegmental lumbar spinal stenosis with minimal incidence of adverse clinical events.

Extramedullary spinal cord tumors at the level of craniovertebral junction are a rare group of neoplasms with their own characteristics. Taking into account the peculiarities of clinical course and complex anatomy of craniovertebral complex, these tumors present a complex diagnostic and surgical problem. A systematic review of literature data on epidemiology, clinical picture, diagnostic methods and dorsal minimally invasive methods of surgical treatment of patients with extramedullary spinal cord tumors of craniovertebral junction was performed.

[A validated new classification for intervertebral disk degeneration]. / Novaya validizirovannaya klassifikatsiya klassov degeneratsii mezhpozvonkovykh diskov.

OBJECTIVE: To develop a new validated classification of intervertebral disc degeneration. MATERIAL AND METHODS: A retrospective observational single-center study included medical records of patients with and without degenerative disease of lumbar intervertebral discs. The interval values of apparent diffusion coefficient (ADC) of intervertebral discs were grouped into degeneration classes. RESULTS: The study included medical records of 100 patients. A quantitative analysis of data showed that mean ADC has a significant correlation with severity of lumbosacral disc degeneration according to classification by Pfirrmann et al. Lumbar intervertebral discs with degeneration grade 3-4 were less homogeneous compared to grade 2-3. Among discs with degeneration grade 4, mean ADC was significantly higher in case of hernia (p=0.01). Conversely, mean ADC was significantly higher in the absence of hernia for discs grade 3 (p=0.04). Combination of all data is presented as original classification of lumbosacral disc degeneration based on mean ADC. CONCLUSION: The developed classification can be recommended for radiologists, neurologists and neurosurgeons.

OBJECTIVE: To study the risk factors of unsatisfactory clinical results after percutaneous laser decompression of the lumbar intervertebral disc (PLDD). MATERIAL AND METHODS: A retrospective observational single-center study included medical records of patients who underwent lumbar PLDD for degenerative spine disease. We analyzed clinical and instrumental parameters potentially affecting the results of lumbar PLDD. RESULTS: Clinical study included 82 patients who underwent PLDD for lumbar intervertebral disc degenerative disease. Mean postoperative follow-up period was 30.8±13.3 months. In 22 (26%) patients, unsatisfactory clinical outcomes were observed. According to binary logistic regression model, comorbidities (p=0.03), duration of disease over 12 months (p=0.03), low preoperative quality of life according to ODI score (more than 50%) (p=0.04), high body mass index (over 25 kg/m2) (p=0.02), severe intervertebral disc (p=0.04) and facet joint degeneration (p=0.01) and intervertebral disc height decrease more than 50% (p=0.01) were significantly associated with unsatisfactory clinical outcomes after lumbar PLDD for degenerative spine disease. CONCLUSION: Identification of these risk factors of unsatisfactory clinical outcomes is important stage of preoperative preparation in patients scheduled for lumbar PLDD.

[Risk factors of adverse clinical outcomes in the elderly and senile patients with stroke-associated pneumonia.]

In the domestic and foreign specialized literature, there are no studies devoted to the study of risk factors of mortality in the older age patients with stroke-associated nosocomial pneumonia. The purpose of the study was to study the risk factors of adverse clinical outcomes in elderly and senile patients with stroke-associated nosocomial pneumonia. The study included 247 elderly and senile patients (139 men, 108 women, mean age -- 74,1±6,3 years) who were hospitalized with signs of ischemic or hemorrhagic stroke. According to the binary logistic regression model, the following parameters are statistically significantly associated with adverse clinical outcomes in the studied group of respondents: age over 75 years (p=0.011), degree of disability according to mRS ≥3 (p=0,009), and C-reactive protein levels over 100 mg/l (p=0,023) and urea more than 7 mmol/l (p=0,044). In order to reduce the incidence of adverse clinical outcomes in patients of the older age group with stroke-associated nosocomial pneumonia, it is necessary to verify the above clinical and laboratory parameters at the early stages of hospitalization.

[Effect of renin-angiotensin-aldosterone system inhibitors on functional activity of the spinal cord and nerve roots in patients with degenerative lumbar spine diseases]. / Vliyanie blokatorov renin-angiotenzin-al'dosteronovoi sistemy na funktsional'nuyu aktivnost' spinnogo mozga i ego koreshkov u patsientov s degenerativnymi zabolevaniyami poyasnichno-kresttsovogo otdela pozvonochnika.

High neuroprotective activity of renin-angiotensin-aldosterone system (RAAS) inhibitors in patients with vascular diseases of the brain and spinal cord has been confirmed. OBJECTIVE: To evaluate the effect of renin-angiotensin-aldosterone system inhibitors on functional activity of the spinal cord and nerve roots in patients with degenerative lumbar spine diseases. MATERIAL AND METHODS: A retrospective observational cohort study was performed. We evaluated clinical and radiological parameters (gender, age of patients, type of antihypertensive drug, concomitant diseases, ODI (6) and SF-36 (7) scores of patient quality of life), functional recovery, increase of signal intensity and its area in T2WIs, localization and maximum spinal canal stenosis, as well as maximum spinal cord and nerve root compression. RESULTS: The study included 117 medical records of respondents (88 men and 29 women aged 56.9±13.2 years) who underwent lumbar spine surgery for degenerative diseases. Arterial hypertension was verified in 68 (58.1%) patients, diabetes mellitus in 22 (18.8%) respondents. Age (p=0.002), diabetes mellitus (p=0.007), arterial hypertension (p=0.015) and antihypertensive therapy (p=0.023) were significantly associated with worse clinical and neurological status of patients. Binary logistic regression model demonstrated that only arterial hypertension was significantly associated with low preoperative quality of life (p=0.002). CONCLUSION: Intake of AT II-1 receptor blockers and angiotensin converting enzyme inhibitors for arterial hypertension is a significant predictor of decrease in signal intensity of the spinal cord and its roots according to T2WIs.

Smoking is an obvious risk factor of adverse events in early and long-term postoperative period after spine surgery including lumbar total disk arthroplasty. Objective. To study the effect of smoking on clinical and radiological outcomes after lumbar total disk arthroplasty. MATERIAL AND METHODS: A single-center retrospective observational cohort study was performed. We have analyzed medical records of patients who underwent single-level lumbar total disk arthroplasty for degenerative disease. RESULTS: The study included 57 medical records of respondents. The examined medical records were divided into two groups - smokers (n=26) and non-smokers (n=31). There were no significant between-group differences in clinical outcomes. Incidence of adverse events was similar too. Kaplan-Meier event-free survival was similar in both groups. There were no significant between-group differences in X-ray data. Development of heterotopic ossification after lumbar total disk arthroplasty was more active in smokers. CONCLUSION: Smoking has no significant effect on clinical and radiological outcomes in patients after single-level after lumbar total disk arthroplasty. On the other hand, smoking significantly increases formation of heterotopic ossification after lumbar total disk arthroplasty.

Genetic polymorphism of local Abkhazian grape cultivars.

Local grape cultivars from different countries of the world are an important part of the gene pool of this culture. Of particular interest are the genotypes of the most ancient regions of viticulture. The territories of the subtropical zone of Georgia and the central part of Abkhazia belong to one of the centers of origin of the cultural grapevine. The purpose of the work was to genotype native Abkhazian grape cultivars, to study their genetic diversity based on DNA profiling data and to compare them with the genotypes of local varieties of other viticultural regions. Samples of plants were taken on the territory of the Republic of Abkhazia in private farmsteads and in the collection of the agricultural firm "Vina i Vody Abkhazii" ("Wines and Waters of Abkhazia"). The genotyping of the Abkhazian cultivars Avasirhva, Agbizh, Azhapsh, Azhizhkvakva, Azhikvaca, Atvizh, Atyrkuazh, Achkykazh, Kachich was carried out using 14 DNA markers, 9 of which are standard microsatellite markers recommended for the identification of grape varieties. To improve our knowledge about the sizes of the identified alleles, we used the DNA of grape cultivars with a known allelic composition at the analyzed loci. Statistical analysis of the data showed that the observed heterozygosity for the analyzed loci exceeded expected values, which indicates a genetic polymorphism of the studied sample of varieties. Evaluation of genetic similarity within the analyzed group based on the results of genotyping at 14 loci showed that the cultivars Kachich and Azhapsh differed from the other Abkhazian varieties. The obtained DNA profiles of the Abkhazian cultivars were checked for compliance with DNA-fingerprints of grape varieties in the Vitis International Variety Catalogue. The Georgian varieties Azhizhkvakva and Tsitska turned out to be synonyms according to DNA profiles, two varieties from the Database (Italian Albana bianca and Georgian Ojaleshi) have differences in DNA-fingerprints from the varieties Atyrkuazh and Azhikvatsa only in one allele, respectively. When comparing the identified Abkhazian grape genotypes, their difference from the sample of Dagestan, Don, Greek, Turkish, Italian, Spanish, and French varieties and genetic similarity with the genotypes of Georgian grapes were shown.

[Registry-based comparison of multiple sclerosis epidemiology trend data in 1999 and 2019: the case of Yaroslavl]. / Dinamika osnovnykh epidemiologicheskikh pokazatelei rasseyannogo skleroza po rezul'tatam sravneniya registrov patsientov 1999 i 2019 gg. v Yaroslavle.

OBJECTIVE: To compare the epidemiological indicators of multiple sclerosis (MS) in Yaroslavl when comparing the 1999 and 2019 registers to study the pathomorphism of the disease in this territory. MATERIAL AND METHODS: During the work, the data of the 1999 and 2019 registers were used, including the age of the debut, the date of diagnosis, the form of the disease, clinical characteristics, the treatment received and its duration. In 1999, 257 patients living in the city of Yaroslavl (155 women and 102 men) were included in the MS registry with a reliable diagnosis of MS according to Poser's criteria with confirmation according to neuroimaging data. In 2019, 479 people living in the territory of Yaroslavl (342 women and 137 men) were included in the register with a diagnosis of MS based on the criteria of MacDonald 2005, 2010, 2017. As of 01.01.19, 970 patients (530 women and 440 men) were included in the patient register of the Yaroslavl region. RESULTS AND CONCLUSION: Clinical and epidemiological review of Yaroslavl MS Registry data in 1999 and 2019 showed significant changes in disease pattern. The prevalence rate increased from 42.6 to 78.5 cases per 100,000 people. The morbidity rate rose from 1.58 to 3.28 cases per 100,000 people. The reasons for the increase are improvement in the diagnostic quality, new diagnostic criteria and the true growth of prevalence and morbidity. The use of disease modifying drugs (DMDs) has extended «the time to EDSS 3,0¼ by 4 years, «the time to EDSS 6,0¼ by 5-8 years.

[The effectiveness of local application of vancomycin powder in the prevention of surgical site infections in spine surgery: a meta-analysis]. / Effektivnost' lokal'nogo primeneniya poroshka vankomitsina v profilaktike infektsii oblasti khirurgicheskogo vmeshatel'stva v spinal'noi khirurgii: metaanaliz.

OBJECTIVE: To perform a meta-analysis of studies examining the effectiveness of the local application of vancomycin powder for the prophylaxis of surgical site infections (SSIs) in spine surgery. MATERIAL AND METHODS: Retrospective cohort studies and prospective randomized clinical trials were searched for in the Pubmed, EMBASE, Cochrane Library and eLibrary databases published from 2008 to December 2018. For the resulting variables, the odds ratio and 95% confidence interval were calculated using random and fixed effects models. Estimation of the degree of heterogeneity is estimated using the coefficient I2. Statistically significant differences were considered differences p<0.05. RESULTS: The meta-analysis included 28 clinical studies that included the results of the local application of vancomycin powder in 17,469 patients after performing various spinal surgical interventions. Two publications had a prospective, randomized, controlled study design. Topical application of vancomycin powder reduces the incidence of SSIs after spine surgery (p<0.0001). The use of vancomycin powder reduces the incidence of SSIs in patients operated on with stabilizing implants (p=0.004). On the other hand, the topical application of vancomycin powder did not affect the prevalence of SSIs in respondents who were operated on without the use of stabilizing implants (p=0.12) or due to deformities of the spine (p=0.06). CONCLUSION: Topical application of vancomycin powder is highly effective in preventing the development of SSIs in patients after spinal surgical interventions.

[The level of subjective well-being in the process of establishment of the diagnosis of epilepsy]. / Uroven' sub''ektivnogo blagopoluchiia lichnosti pri postanovke diagnoza épilepsii.

AIM: To identify the differences in the level of subjective well-being in adult people in the process of refining and establishing the diagnosis of epilepsy. MATERIAL AND METHODS: The study enrolled in total 67 people, including 37 patients, aged from 24 to 51 years, referred to the epileptologist to refine the diagnosis of epilepsy, 15 age-matched healthy controls and 15 age-matched controls with neurological diseases. The Subjective Well-Being Scale modified by M.V. Sokolova was used. RESULTS AND CONCLUSION: An individual experiences negative emotional feelings during the process of refining and establishing the diagnosis of epilepsy, which are strengthened by the specifics of dysphoric disorders in epilepsy. This decreases the level of self-reported subjective well-being that is convincingly confirmed by psychodiagnostic methods.

Analysis of genetic relationships of genotypes of the genus Rosa L. from the collection of Nikita Botanical Gardens using ISSR and IRAP DNA markers.

In connection with the development of breeding and the creation of new plant varieties, the problem of their genotyping and identification is becoming increasingly important, therefore the use of molecular methods to identify genetic originality and assess plant genetic diversity appears to be relevant. As part of the work performed, informative ISSR and IRAP DNA markers promising for the study of genetic diversity of the Rosa L. genus were sought and applied to analysis of genetic relationships among 26 accessions of the genus Rosa L. from the gene pool collection of Nikita Botanical Gardens. They included 18 cultivated varieties and 8 accessions of wild species. The species sample included representatives of two subgenera, Rosa and Platyrhodon. The subgenus Platyrhodon was represented by one accession of the species R. roxburghii Tratt. Cultivated roses were represented by varieties of garden groups hybrid tea, floribunda, and grandiflora. The tested markers included 32 ISSRs and 13 IRAPs. Five ISSR markers (UBC 824, ASSR29, 3A21, UBC 864, and UBC 843) and three IRAPs (TDK 2R, Сass1, and Сass2) were chosen as the most promising. They were used for genotyping the studied sample of genotypes. In general, they appeared to be suitable for further use in studying the genetic diversity of the genus Rosa L. The numbers of polymorphic fragments ranged from 12 to 31, averaging 19.25 fragments per marker. For markers UBC 864 and UBC 843, unique fingerprints were identified in each accession studied. The genetic relationships of the studied species and varieties of roses analyzed by the UPGMA, PCoA, and Bayesian methods performed on the basis of IRAP and ISSR genotyping are consistent with their taxonomic positions. The genotype of the species R. roxburghii of the subgenus Platyrhodon was determined genetically as the most distant. According to clustering methods, the representative of the species R. bengalensis did not stand out from the group of cultivated varieties. When assessing the level of genetic similarity among the cultivated varieties of garden roses, the most genetically isolated varieties were 'Flamingo', 'Queen Elizabeth', and 'Kordes Sondermeldung'; for most of the other varieties, groups of the greatest genetic similarity were identified. This assessment reflects general trends in phylogenetic relationships, both among the studied species of the genus and among cultivated varieties.

[Risk factors for adverse clinical events after carotid arteries stenting in elderly and senile patients.]

The safety of the use of carotid arteries stenting (CAS) in elderly and senile patients remains a controversial issue. The reasons for the development of adverse events in this group of patients after CAS surgical procedure are unknown. The purpose of this study was to evaluate the risk factors for the development of adverse clinical events after CAS surgical procedure in elderly patients group. The study included 147 patients (94 men, 53 women, average age -- 72,1±3,5 years) of elderly and senile patients hospitalized to perform CAS for stenosis of the carotid arteries. According to the constructed model of binary logistic regression, the following parameters are statistically significantly associated with the development of complications after CAS: the presence of stroke in the anamnesis (p=0,013), symptomatic stenosis of the carotid arteries (p=0,011) and the degree of disability according to mRS (Modified Rankin Scale) ≥3 (p=0,002). In order to identify the identified risk factors and minimize the incidence of complications in elderly patients who underwent CAS surgery, a detailed preoperative assessment of their somatic status is necessary with an emphasis on the state of the cardiovascular system.
