Introduction: Primary immunodeficiencies (PID) are a group of rare genetic disorders with a multitude of clinical symptoms. Characterization of epidemiological and clinical data via national registries has proven to be a valuable tool of studying these diseases. Materials and Methods: The Russian PID registry was set up in 2017, by the National Association of Experts in PID (NAEPID). It is a secure, internet-based database that includes detailed clinical, laboratory, and therapeutic data on PID patients of all ages. Results: The registry contained information on 2,728 patients (60% males, 40% females), from all Federal Districts of the Russian Federation. 1,851/2,728 (68%) were alive, 1,426/1,851 (77%) were children and 425/1,851 (23%) were adults. PID was diagnosed before the age of 18 in 2,192 patients (88%). Antibody defects (699; 26%) and syndromic PID (591; 22%) were the most common groups of PID. The minimum overall PID prevalence in the Russian population was 1.3:100,000 people; the estimated PID birth rate is 5.7 per 100,000 live births. The number of newly diagnosed patients per year increased dramatically, reaching the maximum of 331 patients in 2018. The overall mortality rate was 9.8%. Genetic testing has been performed in 1,740 patients and genetic defects were identified in 1,344 of them (77.2%). The median diagnostic delay was 2 years; this varied from 4 months to 11 years, depending on the PID category. The shortest time to diagnosis was noted in the combined PIDs-in WAS, DGS, and CGD. The longest delay was observed in AT, NBS, and in the most prevalent adult PID: HAE and CVID. Of the patients, 1,622 had symptomatic treatment information: 843 (52%) received IG treatment, mainly IVIG (96%), and 414 (25%) patients were treated with biological drugs. HSCT has been performed in 342/2,728 (16%) patients, of whom 67% are currently alive, 17% deceased, and 16% lost to follow-up. Three patients underwent gene therapy for WAS; all are currently alive. Conclusions: Here, we describe our first analysis of the epidemiological features of PID in Russia, allowing us to highlight the main challenges around PID diagnosis and treatment.

The problem studied in this paper consists in the fact that the social and financial risks of investments in innovations are managed in isolation, which leads to limited results (reduces certain risks but raises other risks). This paper is devoted to the search for a new strategy of managing the risks of investments in innovations, which would allow balancing the financial interests of business and the interests of employees and is aimed at developing a framework strategy of the systemic management of all risks based on corporate social responsibility. The methodology of this research is based on regression analysis. The research sample comprises data from 80 countries of the world in 2021. The social and financial risks of investments in innovations are identified, systematized, and quantitatively measured and reconsidered from the positions of the UN SDGs. The paper’s contribution consists in substantiating a systemic interconnection between the social and financial risks of investments in innovations and the possibility of complex management of all these risks based on corporate social responsibility. The theoretical value of this paper consists in overcoming the gap in studying the social and financial risks of investments in innovations. The practical value of the authors’ conclusions and recommendations consists in the developed framework strategy being a practical guide for the systemic management of the risks of investments based on corporate social responsibility.
Основной особенностью двумерного турбулентного течения, постоянно возбуждаемого внешней силой, является возникновение обратного каскада энергии. За счет нелинейных эффектов пространственный масштаб вихрей, создаваемых внешней силой, увеличивается до тех пор, пока рост не будет остановлен размером ячейки. В последнем случае энергия накапливается на этом масштабе. При определенных условиях такое накопление энергии приводит к возникновению системы когерентных вихрей. Наблюдаемые вихри имеют размер ячейки и в среднем изотропны. Численное моделирование является эффективным способом изучения таких процессов. Особый интерес представляет задача исследования турбулентности вязкой жидкости в квадратной ячейке при возбуждении коротковолновой и длинноволновой статическими внешними силами. Численное моделирование проводилось со слабосжимаемой жидкостью в двумерной квадратной ячейке с нулевыми граничными условиями. В работе показано, как на характеристики течения влияет пространственная частота внешней силы, а также величина вязкости самой жидкости. Увеличение пространственной частоты внешней силы приводит к стабилизации и ламинаризации течения. В то же время при увеличении пространственной частоты внешней силы уменьшение вязкости приводит к возобновлению механизма переноса энергии по обратному каскаду за счет смещения области диссипации энергии в область меньших масштабов по сравнению с масштабом накачки.Ключевые слова: течение Колмогорова, вихрь, турбулентность Работа выполнена при поддержке Министерства науки и высшего образования Российской Федерации (госзадания № 075-01056-22-00, № AAAA-A19-119041590048-0 и 075-15-2019-1893).
