Relevance. Verification of a new coronavirus infection (COVID-19) requires clear algorithms for the diagnosis and treatment of patients, depending on clinical, laboratory and instrumental dates. Timely and informed decisions on optimizing management tactics and prescribing proactive anti-inflammatory therapy before development of a complete symptom complex life threatening conditions are needed in some cases. Aim of the study. To analyze the course and outcomes of a new coronavirus infection, depending on the initial characteristics of the patients and treatment options. Materials and methods. A preliminary analysis of the case histories of 129 people hospitalized in the center for treating patients with a new coronavirus infection at North-Western State Medical University n.a. I.I. Mechnikov was made by random sampling. Among the hospitalized patients there were 67 men (51.9%), the average age was 57.9 16.4 years, 62 women (48.1%), and the average age was 60.2 13.6 years. During hospitalization, all patients underwent standard clinical laboratory and instrumental examination, as well as determination of saturation (SpO2), markers of the cytokine storm (CRP, ferritin, AST, D-dimer, fibrinogen, lymphocytes), compute tomography (CT) of the lungs. The effectiveness and safety of therapy was evaluated by the outcome (recovery, death), as well as by the presence of adverse events in the background of the therapy. Statistical processing of the research results was carried out using the Statistica 12 for Windows application software package, the significance of differences between the two relative values was evaluated using the Student t-test (t 2, p 0.05). Results. Fatal outcomes were significantly more frequently recorded among patients of older age groups and males. The presence of concomitant diseases such as obesity, diabetes mellitus, pathology of the cardiovascular system was accompanied by more frequent fatal outcomes. That allows considering comorbidity as a risk factor for severe course and poor prognosis of COVID-19. However, in general, in the presence of the indicated forms of concomitant diseases, it was not possible to establish significant differences with the outcomes of COVID-19, which may be due to an insufficient amount of patients. Predictors of fatal outcome was low values of saturation, the presence of respiratory failure, a significant amount of lung tissue damage (CT-3-4), as well as high values of CRP, ferritin, AST, D-dimer, neutrophilia, lymphopenia, thrombocytopenia. The use of anticytokine drugs (ACD) in complex therapy can be considered a favorable predictor of outcome, which indicates the advisability of wider use. The materials of the study allow not only a preliminary assessment of the course and effectiveness of complex therapy using anticytokine drugs with COVID-19 in patients with comorbid diseases, but also to develop therapeutic and diagnostic algorithms in patients of this category.
The review presents new indications to help with diagnosis and treatment of ventricular arrhythmia (VA) in patients with various etiologies of rhythm disturbances, including patients with coronary artery disease, cardiomyopathies, channelopathies, inflammatory heart disease, neuromuscular disease, and congenital heart defects. Algorithms for diagnostic evaluation at first presentation with VAs in patients without known cardiac disease are given.
BACKGROUND: In recent years, in traumatology and orthopedics, statistical methods of survival analysis have been used to assess long-term treatment results, which make it possible to take into account censored clinical observations. This method of statistical analysis allows to take into account both cases of attrition from care and cases of incomplete follow-ups. There is no concurrent point of view on the dependence of the long-term results of hip and knee arthroplasty on the comorbidity of a patient. This circumstance fosters a special study using survival analysis. AIM: To study the long-term results of total hip and knee arthroplasty in the patients with osteoarthritis. To determine the patients quality of life depending on the presence of pronounced concomitant pathology. MATERIALS AND METHODS: The groups of patients with comorbidity and without significant concomitant pathology have been compared. The first group included 806 patients aged 19 to 88 years who underwent primary total hip replacement in the Clinic of Traumatology and Orthopedics of the North-Western State Medical University named after I.I. Mechnikov from 2014 to 2018 in connection with osteoarthritis. The second group consisted of 376 patients aged 43 to 85 years who underwent primary total KR due to osteoarthritis in the V.A. Baranov Republican Hospital (Petrozavodsk) in 20162019. Statistical data processing and graph design have been carried out with R programming language with open access via https://cran.r-project.org. The probability of maintaining a satisfactory assessment of the quality of life by a certain observation point t (year of observation) has been assessed using the KaplanMayer method. The logrank test has been used in order to compare the probability of maintaining a satisfactory assessment of quality of life during the entire follow-up period in the groups of patients with and without polymorbidity. RESULTS: At the end of the 5th year of follow-up, the probability of maintaining excellent and good quality of life after hip replacement with a 95% confidence interval was 0.88 (0.81; 0.94) in the patients without comorbidity, 0.84 (0.79; 0.88) in the patients with severe concomitant pathology. Test statistics (Z = 0.93) and p = 0.31 indicate statistically insignificant differences in survival curves between the groups of patients with varying degrees of comorbidity. When analyzing the five-year results of the knee replacement, the quality of life among patients with high and low comorbidity did not differ significantly. The probability of excellent and good quality of life at the 5th year of follow-up in practically healthy patients and in cases of mild therapeutic disease was 0.78 (0.67; 0.88); with a high degree of comorbidity 0.74 (0.65; 0.81). CONCLUSIONS: By the end of the 5th year of follow-up of the patients who have undergone hip or knee replacement due to osteoarthritis, an excellent and good quality of life can be expected on average in 80% of the patients. Satisfactory and unsatisfactory in 20% of the patients. Excellent and good quality of life 5 years after hip or knee arthroplasty in the patients with severe comorbidity does not significantly differ from that in the practically healthy patients without comorbidity (р 0,05).
Aim. The goals of this research are to define the frequency of the coronary arteries visualization possibilities depending on various factors at routine echocardiography and estimate to the relation of coronary flow ultrasound parameters to prognosis of the adverse outcomes in the subsequent year.Material and methods. The study comprises 581 consecutive patients. All patients performed echocardiography following standard method with an additional tab called «Coronary» which was set to visualize coronary arteries. Also all patients underwent a standard examination and debriefing of anamnesis. Observation of patients was the next year after echocardiography. The end points in the study – death from any cause, myocardial infarction (MI), death/ MI, myocardial revascularization operations - stenting and aortocoronary bypass (CABG). The analysis of clinical outcomes was carried out using the study of medical history and outpatient cards, interviewing patients at the time of admission, as well as the method of telephone survey of patients or their next of kin. ROC analysis as well as subgroup survival analysis using the Kaplan-Meier method was performed.Results. The possibility to visualize the segments of coronary arteries and to estimate the coronary flow was in 91% of cases, or 526 patients. Women predominated among the patients (59.7% versus 40.3%). During follow-up, 73 patients recorded endpoints: 23 people died, 4 patients suffered non-fatal MI. 24 patients underwent CABG, 22 patients – myocardial revascularization. Depending on the quartile distribution by body mass index and age, a significant difference in visualization was not identified. Mortality was observed significantly more frequent when the flow velocity in the left coronary artery/proximal left artery descending/circumflex artery was higher than 64 cm/s. Flow velocity in left coronary artery /proximal left artery descending 64 cm/s was the cut-off value predicting MI with 100% sensitivity, 73,4% specificity (p<0.0001). Conclusion. Coronary flow velocity parameters provide long-term prognostic value that can be used to identify individuals with high risk of developing adverse cardiovascular events. Key words: coronary flow velocity, echocardiography, coronary artery, adverse events>˂0.0001).Conclusion. Coronary flow velocity parameters provide long-term prognostic value that can be used to identify individuals with high risk of developing adverse cardiovascular events.
Introduction Total knee arthroplasty is the treatment of choice in orthopedic practice for patients with late stage knee osteoarthritis. However, arthroplasty has not only benefit results and the service life of the endoprothesis is limited. The use of modern conservative therapy and joint-preserving surgions allowed to delay or to avoid knee arthroplasty. Purpose. The study purpose is the analysis of publications with negative results of knee arthroplasty in patients with knee osteoarthritis. Materials and methods. The electronic Pub-Med/MEDLINE and eLibrary databases were searched for reviews published between 2002 and 2022. A keyword search was also done using the terms: knee joint osteoarthritis, total knee replacement/arthroplasty, complications, patient satisfaction, indications/contraindications for surgery; related definitions and descriptions were extracted. Results. The negative consequences of total knee arthroplasty are heterogeneous. Complications can be local and systemic such as surgical site infection, periprosthetic fracture, aseptic loosening (asepticinstability) of theendoprosthesis and its wearand the implant failure. The researchers data indicate increasing the number of patients who are not satisfied with the results of arthroplasty both in the short term and in the long-term after the operation, due to the natural wear of the prosthesis. Patients are not satisfied with the results of the operation 8% -30%. In recent years, there have been more publications devoted to the limitation of indication for arthroplasty in pftients with knee osteoarthritis. The replacement of the knee joint with an implant was done unreasonably in great number of cases.A number of patients after total knee arthroplasty require revision surgery within the first 5 years. Currently, the risk of failure of knee arthroplasty with the revision surgery in 10 years after primary arthroplasty is 5-6.8%. The main reasons for revision surgery after primary knee arthroplasty are periprosthetic infection and instability of the implant components, while the results of revision surgery are worse than the primary arthroplasty.
