В статье представлен аналитический обзор научной отечественной и зарубежной литературы за последние 15 лет, посвященный анатомо-физиологическим и клиническим аспектам лимфаденитов челюстно-лицевой области. Синдром лимфаденопатии (ЛАП) встречается при большой группе различных заболеваний и представляет собой увеличение одной или нескольких групп лимфатических узлов в основном за счет гиперплазии фолликул лимфоидной ткани, что может быть проявлением как реактивных состояний, так и злокачественных процессов. В настоящее время в клинической практике стоматолога во всем мире отмечается увеличение распространенности лимфаденитов челюстно-лицевой области, в том числе у детей, что, с одной стороны, обусловлено неблагоприятной экологической ситуацией, а с другой – изменениями иммунологической реактивности человеческого организма. В связи с этим вопросы дифференциальной диагностики, лечения и профилактики лимфаденитов приобретают особую значимость для современного здравоохранения Республики Беларусь.
The article presents an analytical review of the scientific domestic and foreign literature for the last 15 years, devoted to the anatomical, physiological and clinical aspects of lymphadenitis of the maxillofacial region. Lymphadenopathy syndrome (LAP) is occurred in a large group of various diseases and is an enlargement of one or more groups of lymph nodes mainly due to hyperplasia of lymphoid follicles tissue, which can be a manifestation of both reactive states and malignant processes. Currently, in the clinical practice of the dentist around the world, there is an increase in the prevalence of lymphadenitis of the maxillofacial region, including in children. On the one hand it is due to the unfavorable environmental situation, and on the other – changes in the immunological reactivity of the human body. In this regard, the issues of differential diagnosis, treatment and prevention of lymphadenitis are of particular importance for modern healthcare in Republic of Belarus.

Все чаще раком молочной железы (РМЖ) заболевают женщины с нереализованной репродуктивной функцией. Современное химиотерапевтическое лечение обладает гонадотоксичным эффектом и может приводить к снижению овариального резерва. Использование вспомогательных репродуктивных технологий (ВРТ) – возможность сохранения фертильности до начала химиотерапевтического лечения.Группу исследования составили 18 женщин с диагнозом РМЖ. В 12 случаях для медико-генетического консультирования пациентки направлены до проведения специального лечения (химиотерапия) для рассмотрения вопроса о возможности проведения ВРТ и последующей витрификации яйцеклеток или эмбрионов. Также проведено преконцепционное медико-генетическое консультирование у 6 женщин после противоопухолевого лечения по поводу РМЖ. В 41,7% случаев наблюдается семейная форма РМЖ. Ни в одном случае ненаследственного РМЖ не установлена мутация в гене BRCA.ВРТ проведены в 58,3%, в 85,7% завершились витрификацией яйцеклеток или эмбрионов. Отказ от проведения ВРТ был связан как со стадией РМЖ, так и с осложненным гинекологическим анамнезом, приводящим к риску осложнений ВРТ.
More often women with unrealized reproductive function develop breast cancer (BC). Chemotherapeutic treatment has a gonadotoxic effect and can lead to a decrease ovarian reserve. The use of assisted reproductive technologies (ART) is the ability to preserve fertility before starting chemotherapeutic treatment.The study group consisted of 18 women diagnosed with BC. In 12 cases for genetic counseling, the patients were referred before special treatment (chemotherapy) to consider the possibility of ART and subsequent vitrification of oocytes or embryos. Also, pre-conceptual medical and genetic counseling was carried out in 6 women after treatment for breast cancer in remission.ART was performed in 58.3%, and in 85.7% it was completed with vitrification of oocytes or embryos. Refusal to perform ART was associated with both the stage of breast cancer and a complicated gynecological history, leading to the risk of complications of ART.

Сердечно-сосудистые заболевания (ССЗ) являются ведущей причиной смерти во всем мире, на их долю приходится примерно 29,2% от общего числа смертей. Из всех смертей, связанных с ССЗ, около 43% вызваны ишемической болезнью сердца, 33% – цереброваскулярными заболеваниями, 23% – гипертонической болезнью и другими сердечными заболеваниями. Изменения, происходящие в сердечно-сосудистой системе при развитии ССЗ, рассматриваются как континуум их развития. Концепция континуума может использоваться для описания сердечно-сосудистых заболеваний в целом или в конкретных сосудистых руслах (например, ишемическая болезнь сердца или цереброваскулярное заболевание). Блокаторы рецепторов ангиотензина II (БРА) являются антигипертензивными лекарственными средствами, имеющими значительную доказательную базу эффективности и безопасности, используемыми для снижения риска развития ССЗ. Клинические доказательства их эффективности продолжают накапливаться. Определен ряд благоприятных плейотропных эффектов, повышающих их эффективность. В обзорной статье обсуждаются результаты знаковых клинических испытаний БРА, опубликованные за последние годы. Важное место отведено рассмотрению клинических эффектов кандесартана (Касарк) как одного из самых эффективных препаратов данной группы.
Cardiovascular disease (CVD) is the leading cause of death worldwide, accounting for approximately 29.2% of total deaths. Of all CVD-related deaths, about 43% are due to ischemic heart disease, 33% to cerebrovascular disease, and 23% to hypertension and other heart diseases. Changes occurring in the cardiovascular system during the development of CVD are considered as a "continuum" of their development. The concept of a continuum can be used to describe cardiovascular disease in general or in specific vascular beds (eg coronary artery disease or cerebrovascular disease). Angiotensin II receptor blockers (ARBs) are antihypertensive drugs with significant evidence of efficacy and safety used to reduce the risk of developing CVD. Clinical evidence for their effectiveness continues to accumulate. A number of favorable pleiotropic effects have been identified that increase their effectiveness. This review article discusses the results of landmark ARB clinical trials published in recent years. An important place in the ARB group is given to the consideration of the clinical effects of kаndesartan (Casark) as one of the most effective drugs in this group.

Published: February 2022

Lost wax casting is a known process for making complex shaped parts. Based on the known technology, one can imagine a technological variant that involves obtaining the model through rapid prototyping processes, and the mold will be made around this model. Subsequently, the model, made of a soluble material will be dissolved, leaving the mold with the corresponding inner cavity. A frequently encountered problem is the need to verify the dimensional accuracy of the model, especially in conditions where its complexity is special.
The paper presents the design of the model starting from the shape of the piece to be obtained, the realization of the model using the technology of filament deposition in a molten state and the inspection of the model obtained using a video scanning system.

Abstract
Single-crystal Si (c-Si) bottom-gate thin-film transistors (BG-TFTs) were fabricated using all sputtering processes. Laser doping from sputter-deposited Sb-doped amorphous Si film was proposed, by which n+ c-Si with resistivity and contact resistivities of 1.5 × 10−3 Ωcm and 2.1 × 10−5 Ωcm2, respectively, were fabricated. In addition, thin (50 nm) and low-heat conductive titanium was proposed for BG to realize continuous lateral crystal growth in Si film above the edge of BG. The fabricated n-channel c-Si BG-TFTs exhibited a field-effect mobility of 75 ± 21 cm2 V−1s−1, subthreshold swing of 0.612 ± 0.110 Vdec−1, and threshold voltage of 4.9 ± 1.38 V. Lack of bottom Si/SiO2 interface quality was indicated to be the origin of insufficient mobility.

Abstract
Most large galaxies host supermassive black holes in their nuclei and are subject to mergers, which can produce a supermassive black hole binary (SMBHB), and hence periodic signatures due to orbital motion. We report unique periodic radio flux density variations in the blazar PKS 2131−021, which strongly suggest an SMBHB with an orbital separation of ∼0.001–0.01 pc. Our 45.1 yr radio light curve shows two epochs of strong sinusoidal variation with the same period and phase to within ≲2% and ∼10%, respectively, straddling a 20 yr period when this variation was absent. Our simulated light curves accurately reproduce the “red noise” of this object, and Lomb–Scargle, weighted wavelet Z-transform and least-squares sine-wave analyses demonstrate conclusively, at the 4.6σ significance level, that the periodicity in this object is not due to random fluctuations in flux density. The observed period translates to 2.082 ± 0.003 yr in the rest frame at the z = 1.285 redshift of PKS 2131−021. The periodic variation in PKS 2131−021 is remarkably sinusoidal. We present a model in which orbital motion, combined with the strong Doppler boosting of the approaching relativistic jet, produces a sine-wave modulation in the flux density that easily fits the observations. Given the rapidly developing field of gravitational-wave experiments with pulsar timing arrays, closer counterparts to PKS 2131−021 and searches using the techniques we have developed are strongly motivated. These results constitute a compelling demonstration that the phenomenology, not the theory, must provide the lead in this field.

Plusieurs hypothèses ont été avancées au sujet des effets potentiels du bilinguisme sur le développement cognitif des enfants et leur réussite scolaire. Toutefois, peu d’études cherchent à les départager empiriquement, et la littérature existante est essentiellement consacrée aux États-Unis. Dans cet article, nous utilisons une enquête récente, représentative des adultes résidant en France (l’enquête « FQP » – « Formation et Qualification professionnelle » ) pour étudier la corrélation entre l’exposition à un environnement bilingue à l’âge de 5 ans (qu’il s’agisse d’une langue régionale ou étrangère) et la trajectoire scolaire ultérieure. Nous explorons aussi si cette association varie en fonction des différentes caractéristiques de cette population. Nous montrons qu’une exposition bilingue précoce est associée à une moindre réussite scolaire, particulièrement en fin de parcours scolaire. Cette corrélation négative est plus forte parmi les individus d’origine maghrébine, et à l’inverse moins marquée chez les individus originaires d’Europe du Sud. Elle concerne aussi ceux qui ont été exposés à une langue régionale dans l’enfance. Enfin, ce désavantage est proportionnellement plus marqué chez les individus dont les parents sont les plus diplômés. Ces résultats montrent l’importance d’étudier les corrélations entre l’exposition au bilinguisme et les trajectoires scolaires en tenant compte de l’hétérogénéité des caractéristiques des individus concernés.
Correlation of Platelet Counts with Coronavirus Disease 2019 Outcome in the Second Wave at a Tertiary Care Center
Authors: Rajanna Avinash H. , Ramanna Binduraj , Bellary Vaibhav S. 
Published: February 2022

Background:
A novel coronavirus, severe acute respiratory syndrome coronavirus 2, was first identified in December 2019 as the cause of a respiratory illness designated coronavirus disease 2019 (COVID-19). Laboratory parameters particularly the inflammatory markers such as D-dimer, C-reactive protein, ferritin, and others have been studied extensively and have been applied in categorizing the disease severity as well. However, studies regarding the role of platelet counts in the disease pathophysiology are limited.

Aims
(1) To assess platelet counts in COVID-19 patients, (2) To correlate platelet counts with clinical outcome of COVID-19 patients.

Materials and Methods
The present study was conducted on 200 patients admitted to ESIC MC and PGIMSR MODEL HOSPITAL, Bengaluru, during the study period from August 2020 to July 2021. Data were collected from case files of patients presenting to the Department of General Medicine Triage and COVID Ward/intensive care unit at ESIC Bangalore, fulfilling the inclusion criteria.

Results
The mean platelet counts of the patients admitted with COVID-19 are 2.18 ± 1.32 × 105/mm3. Platelets among those who were discharged were 2.16 ± 1.09 × 105/mm3 and those among those who died was 1.71 ± 0.56 × 105/mm3. This difference was statistically significant with a P = 0.03. We also see that the lymphocyte counts are 14.03 ± 10.75% among those who were discharged and 10.13 ± 5.89% among those who succumbed to death.

Conclusion
The present study concludes that COVID-19 patients with thrombocytopenia and lymphopenia are at increased risk of mortality. Hence, platelet count and lymphocyte count can be taken as prognostic indicators of COVID-19.

Prognostic significance of novel inflammatory markers in extensive-stage small-cell lung cancer
Authors: Yilmaz Hatice , Yersal Özlem 
Published: February 2022

Objective:
Novel hematological inflammation-based parameters, such as neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), prognostic nutritional index (PNI), lymphocyte-to-C-reactive protein ratio (LCR), systemic inflammatory response index (SIRI), and hemoglobin-to-red cell distribution width ratio (HRR), have been determined to be linked to prognosis of various cancer types, although the predictive impact of these parameters on extensive-stage small-cell lung cancer (SCLC) is not exactly known. In this study, we aimed to demonstrate the prognostic significance of these novel parameters.

Materials and Methods:
This retrospective study included 162 patients who were under follow-up with a diagnosis of extensive-stage SCLC. The receiver operating characteristic curve analysis revealed that the optimal cutoff values for NLR, SII, PNI, LCR, SIRI, and HRR were 2.34, 787, 46.13, 0.29, 1.5, and 1.05, respectively. Cox regression analyses were done to determine the predictive impact of these parameters on progression-free survival (PFS) and overall survival (OS).

Results:
Patients with higher LCRs and HRRs had longer PFS and OS than patients with lower LCRs and HRRs (P < 0.001, P < 0.001, P < 0.001, P < 0.001, respectively). PFS and OS were significantly shorter in the group with high SIRIs than in the group with low SIRIs (P < 0.001, P < 0.001, respectively). A multivariate analysis identified LCR and SIRI as independent prognosticators for both PFS and OS (P < 0.001, P < 0.001; P = 0.002, P < 0.001, respectively), and HRR as an independent prognostic factor only for OS (P = 0.046).

Conclusion:
LCR, SIRI, and HRR are independent prognostic parameters that predict survival times in patients with extensive-stage SCLC.
