INTRODUCTION: Chronic periodontal inflammation is provoked by persistence of subgingival bacterial flora and is mediated through the production of proinflammatory cytokines that induce the innate immune reactions. АIM: To establish the interrelation of secretion of interleukin 1 and immune component of soluble CD14 co-receptor with the main periodontopathogenic microorganisms in patients with chronic generalized periodontitis. MATERIALS AND METHODS: A clinical and laboratory examination of patients with chronic generalized periodontitis (n = 100) and individuals with the intact parodontium (n = 63) was conducted. Molecular genetic studies (isolation of periodontal pathogens by polymerase chain reaction in real time), immune enzyme assay (isolation of interleukin 1 and soluble CD14 co-receptor) and statistical analysis of the data obtained were performed. RESULTS: The frequency of isolation of periodontopathogenic bacteria in patients with the diagnosis of chronic periodontitis was 96.4% (T. forsythia 81%, р 0.001; P. gingivalis 69%, р 0.001; Tr. denticola 63%, р = 0.054). In 25% of cases, C. Albicans (р 0.001), in 37% Pr. intermedia (р 0.001) and in 30% A. actinomycetemcomitans (р 0.001) were isolated. The average concentrations of soluble CD14 co-receptor were 2.13 [1.89; 2.76] pg/ml in the control group and 20.3 [17.3; 22.5] ng/ml in the group of patients with chronic periodontitis (р 0.001). Concentrations of interleukin 1 were 3.187 [2.356; 4.633] pg/ml in the control group and 33.68 [17.255; 56.915] pg/ml in the group of patients with chronic periodontitis (р 0.001). CONCLUSION: Inflammation of periodontal tissues is supported by the factors of aggression and toxins not only of known periodontal pathogens, but also by their associations, which leads to enhancement of virulence factors and increase in secretion of interleukin 1 and soluble CD14 co-receptor, which, in turn, causes destruction of alveolar bone.
简介:慢性牙周炎症是由牙龈下菌群的持续存在引起的,并通过促炎细胞因子的产生介导,诱导先天免疫反应。 АIM:探讨慢性广泛性牙周炎患者白细胞介素1分泌及可溶性CD14共受体免疫组分与主要牙周致病微生物的关系。 材料与方法:对100例慢性广泛性牙周炎患者和63例完整牙周炎患者进行了临床和实验室检查。进行分子遗传学研究(实时聚合酶链反应分离牙周病原菌)、免疫酶测定(分离白细胞介素1和可溶性CD14共受体)并对所得数据进行统计分析。 结果:慢性牙周炎患者牙周致病菌检出率为96.4%,其中连翘检出率为81%,检出率为0.001;牙龈卟啉卟啉菌69%,0.001;齿齿苋63%,r = 0.054)。在25%的病例中分离到白色念珠菌(0.001),37%分离到中间pr(0.001), 30%分离到放线菌comitans(0.001)。可溶性CD14共受体平均浓度为2.13 [1.89;对照组为2.76 pg/ml,对照组为20.3 pg/ml [17.3;22.5] ng/ml,慢性牙周炎患者组差异有统计学意义(p < 0.001)。白细胞介素1浓度为3.187 [2.356];对照组为4.633 pg/ml,对照组为33.68 pg/ml;[56.915]慢性牙周炎患者组(p < 0.001)。 结论:牙周组织炎症不仅与已知牙周病原体的侵袭和毒素有关,还与它们的关联有关,导致毒力因子增强,白细胞介素1和可溶性CD14共受体分泌增加,从而导致牙槽骨破坏。

INTRODUCTION: The increasing incidence of pulmonary embolism (PE) and high mortality from it necessitates development of new echocardiographic (EchoCG) criteria for assessing the severity of pressure and volume overload of the right ventricle (RV) in patients with PE. AIM: To perform critical analysis of the developed EchoCG criteria of overload of the right heart chambers in PE with the aim to determine severity of the course and outcomes of the disease. MATERIALS AND METHODS: The study included 428 patients with PE divided to 4 groups: group 1 42 patients with recorded death, group 2 51 patients with hemodynamically significant disease, group 3 193 hemodynamically stable patients with EchoCG signs of the overload of the right ventricle, group 4 142 patients with no identified symptoms. Comparison of the developed EchoCG criteria was conducted: the volume of tricuspid regurgitation, its ratio to the volume of the right atrium and the stroke volume of the heart, and also the pressure in the pulmonary trunk, the pressure gradient on the pulmonic valve and its ratio to the pressure gradient on the tricuspid valve in the studied groups with the determination of threshold values having diagnostic and prognostic significance. RESULTS: It was found that the level of the estimated pressure gradient on the pulmonic valve has statistically significant correlation with the hemodynamic significance of the course of the disease (r = 0.91, р 0.01) and fatal outcome (r = 0.99, р 0.01) and possesses high sensitivity (more than 92.7%) and specificity (more than 97.8%). This parameter is proved to be the most important prognostic EchCG criterion. To determine the expression of the RV dysfunction and the priority flow of blood from its cavity, the following parameters equivalent to EhcoCG, such as the ratio of pressure gradient on the pulmonic artery to the pressure gradient on the tricuspid valve and the ratio of the tricuspid regurgitation volume to the stroke volume, are also significant. CONCLUSION: Calculation of the pressure gradient on the pulmonic valve and its correlation with the pressure gradient on the tricuspid valve, just as the ratio of the volume of tricuspid regurgitation to the stroke volume can be reliable criteria for assessment of the hemodynamic significance of PE and predictors of its outcome.
导论:肺栓塞(PE)发病率的增加和由此导致的高死亡率要求开发新的超声心动图(EchoCG)标准来评估PE患者右心室(RV)压力和容量过载的严重程度。目的:对发展的超声心动图标准进行批判性分析,以确定PE的病程和结局的严重程度。 材料与方法:将428例PE患者分为4组:1组有死亡记录的患者42例,2组有血流动力学显著疾病的患者51例,3组有右心室负荷超声心动图体征血流动力学稳定的患者193例,4组无明确症状的患者142例。比较各研究组制定的超声心动图标准:三尖瓣反流容积、与右心房容积、心脏搏容积之比,以及肺动脉干压力、肺动脉瓣压力梯度及其与三尖瓣压力梯度之比,确定阈值具有诊断和预后意义。 结果:肺动脉瓣估计压力梯度水平与病程血流动力学意义(r = 0.91, r = 0.01)及死亡结局(r = 0.99, r = 0.01)有统计学意义,且具有较高的敏感性(大于92.7%)和特异性(大于97.8%)。该参数被证明是最重要的心电图预后标准。为确定右心室功能障碍的表达及其腔内优先血流情况,相当于EhcoCG的肺动脉压力梯度与三尖瓣压力梯度之比、三尖瓣返流容积与脑卒中容积之比等参数也具有显著性意义。 结论:肺动脉瓣压力梯度及其与三尖瓣压力梯度的相关性,与三尖瓣返流容积与脑卒中容积之比一样,可作为评价肺动脉瓣血流动力学意义及预后预测指标的可靠依据。

INTRODUCTION: The use of synthetic cannabinoids (SCs) is an urgent healthcare problem, due to, among other things, a high number of complications. AIM: To systematize the peculiarities of clinical presentation, somatic complications, effectiveness of empirical approaches to therapy, and probable outcomes of delirium induced by exposure to SCs. MATERIALS AND METHODS: The analysis of scientific publications selected by the keywords in eLibrary, СNKI, PubMed databases, was conducted. According to PRISMA recommendations, 20 articles were taken for analysis. RESULTS: Today, it is impossible to predict the period when SC-induced delirium may occur. It can start after one-time intake of even small dose, and can occur both due to intoxication and with the underlying withdrawal state on the 2nd4th days after the last use. Besides classic symptoms, the clinical picture of delirium is characterized by many symptoms of schizophrenic psychoses: hallucinations of threatening or drug-addicted content; secondary paranoid delusion, less expressed than hallucinations; aggressiveness and agitated behavior; some formal thinking disorders; rarely, KandinskiClerambault and oneiroid syndromes. There are reported cases of severe somatic complications in the form of depression of consciousness, rhabdomyolysis, acute renal failure, cardiomyopathy, myocardial infarction, epilepsy, infectious complications with the underlying weakened immunity. Therapy of SC-induced delirium includes detoxification and metabolic therapy, administration of antipsychotics and tranquilizers; use of resuscitation measures in case of depression of consciousness and development of life-threatening conditions. SC-induced delirium lasts from several hours to several days. In most cases, it terminates with complete recovery with amnesia of the period of confusion and asthenia, but in some cases fatal outcomes are reported caused not only by accidents such as road accidents or suicide, but also by somatic complications (most often of infectious character, or multi-organ failure). CONCLUSION: SСs remain relevant due to high frequency of their use and continuous emergence of new analogs to substances of this group. They have multidirectional effect, and so far it is difficult to predict at what period the delirium induced by them may occur.
导言:合成大麻素(SCs)的使用是一个紧迫的医疗保健问题,除其他外,由于大量并发症。 目的:系统分析SCs诱发谵妄的临床表现、躯体并发症、经验治疗方法的有效性和可能的结果。材料与方法:以library, СNKI, PubMed数据库中的关键词选择科学出版物进行分析。根据PRISMA的建议,选取了20篇文章进行分析。 结果:目前尚无法预测sc诱导谵妄发生的时间。它可以在一次性摄入甚至小剂量后开始发生,也可以因中毒而发生,也可以在最后一次使用后第24天出现潜在的戒断状态。除了经典症状外,谵妄的临床表现还具有许多精神分裂症精神病的症状:具有威胁性或药物成瘾内容的幻觉;继发性偏执妄想,比幻觉表达少;攻击性和激动的行为;一些形式思维障碍;很少有康定斯基综合征、克莱兰博综合征和类血管瘤综合征。有严重躯体并发症的报道,表现为意识压抑、横纹肌溶解、急性肾功能衰竭、心肌病、心肌梗死、癫痫、感染性并发症以及潜在的免疫力减弱。sc性谵妄的治疗包括解毒和代谢治疗,抗精神病药物和镇静剂的使用;在意识衰退和危及生命的情况下使用复苏措施。sc引起的谵妄持续数小时至数天。在大多数情况下,它以完全恢复和神志不清和虚弱时期的失忆而结束,但在某些情况下,致命的结果不仅是由交通事故或自杀等事故引起的,而且还由躯体并发症引起(最常见的是传染性特征,或多器官衰竭)。结论:SСs因其使用频率高且不断出现新的类似物而保持相关性。它们具有多向作用,目前还难以预测在什么时期会发生由它们引起的谵妄。

INTRODUCTION: The current stage of development of dental implantology permits to perform a complete dental rehabilitation even in complicated clinical situations. However, there are some difficulties which prevent achievement of a high success of implantological treatment in certain somatic pathologies that manifest in the form of systemic inflammation, and present relative contraindications for implantation. Important general somatic pathologies include chronic obstructive pulmonary disease, atherosclerosis, non-insulin-dependent diabetes mellitus, osteoporosis, etc., they are associated with the risk of acute inflammatory response of an organism to surgical implantological intervention. The risk of unpredictable complications also increases because of insufficiently wide laboratory diagnostic spectrum for planning dental implantation that includes a biochemical blood test, coagulogram, reaction to the presence of specific infections and viral diseases. This list of diagnostic data is not always sufficient for a complete prognosis of success of planned treatment in patients with a complicated general somatic or dental status. Besides, the interrelation between dental chronic diseases and general somatic pathologies which in some cases have common etiopathogenetic factors, is often not taken into account, but without the adequate diagnostic range they often remain unnoticed and lead to persistent complications in different periods after completion of treatment. Development of technologies of surgical and orthopedic dentistry permits to provide full dental care to patients even with different pathologies of organs and systems. But in this case, of importance is extended laboratory diagnostics aimed at identification of factors of chronic systemic inflammation, vascular risk, bacterial threats, for example, evaluation of some interleukins, tumor necrosis factor, C-reactive protein. CONCLUSION: A complex of clinical, laboratory and instrumental diagnostic methods will permit to adequately evaluate risk for treatment failure and construct a prognostic tactics of complex therapy, thereby reducing the probability for unpredictable complications in dental implantation in patients with different somatic pathologies.
简介:目前的发展阶段的牙科种植允许执行一个完整的牙科康复,即使在复杂的临床情况。然而,在某些以全身炎症为表现形式的躯体病变中,存在一些困难,这些困难阻碍了植入治疗的高成功率,并且存在植入的相对禁忌症。重要的一般躯体病变包括慢性阻塞性肺疾病、动脉粥样硬化、非胰岛素依赖型糖尿病、骨质疏松症等,它们与机体对外科植入干预的急性炎症反应风险相关。不可预测的并发症的风险也增加了,因为没有足够广泛的实验室诊断范围来规划牙齿种植,包括生化血液检查、凝血图、对特定感染和病毒性疾病的反应。这一诊断数据列表并不总是足以对具有复杂的一般躯体或牙齿状况的患者的计划治疗成功的完整预后。此外,牙齿慢性疾病与一般躯体病理之间的相互关系,在某些情况下具有共同的致病因素,往往没有得到考虑,但如果没有适当的诊断范围,它们往往被忽视,并导致治疗完成后不同时期的持续并发症。外科和矫形牙科技术的发展允许为具有不同器官和系统病理的患者提供全面的牙科护理。但在这种情况下,重要的是扩展实验室诊断,旨在识别慢性全系统炎症,血管危险,细菌威胁的因素,例如,一些白细胞介素,肿瘤坏死因子,c反应蛋白的评估。结论:综合临床、实验室和仪器诊断方法可以充分评估治疗失败的风险,建立综合治疗的预后策略,从而减少不同躯体病变患者种植牙时不可预测并发症的发生概率。

INTRODUCTION: The ongoing pandemic of a new coronavirus infection COVID-19 (COronaVIrus Disease 2019) places high demands on the activity of PCR-laboratories (laboratories performing polymerase chain reaction). The medical personnel experience overloads due to stay in the red zone wearing the individual protection means, and also in association with a high personal responsibility for the result of their work. One of the criteria that is proposed for professional selection with the aim of increasing the effectiveness of the work of personnel of PCR-laboratories, is the emotional quotient (EQ). AIM: To analyze the state of systemic hemodynamics and heart rate variability in medical workers of PCR-laboratories with different emotional intelligence working in condition of COVID-19 pandemic using means of individual protection against the biological factor. MATERIALS AND METHODS: The extent of health risk and tension of adaptation mechanisms during the work were evaluated by parameters of systemic hemodynamics (tonometry, pulse oximetry) and heart rate variability (cardiorhythmography). Thirty three individuals with the working period in a PCR-laboratory from 1 to 33 months were examined. The average age of the participants at the time of inclusion in the study was 32.4 1.44 years. In 33.7%, EQ corresponded to the medium level (81120 points), and in 66.7% to the high level (121168 points). RESULTS: Before the start of the work shift, increased blood supply to tissues in personnel with high EQ was achieved by increased heart activity: cardiac output (CO) 3938.9 ml/min, interquartile range (IQR) = 3404.24230.2 ml/min with the underlying reduction of vessel tone: total peripheral vascular resistance (TPVR) 1922.8 dyn s/cm5, IQR = 1636.52085.8 dyn s/cm5. After the end of the shift, to these compensatory mechanisms (CO 4284.7 ml/min, IQR = 3935.44688.8 ml/min; TPVR 1692.4 dyn s/cm5, IQR = 1584.61903.1 dyn s/cm5), increased myocardial oxygen consumption (MOC; 7917.5 RU, IQR = 7430.28811.0 RU) added as a reaction to the muscular component of labor activity. In individuals with average EQ, these mechanisms were less pronounced in considerable mental stress: before the shift CO 3722.0 ml/min, IQR = 3163.13739.0 ml/min, p = 0.013; TPVR 2303.1 dyn s/cm5, IQR = 2058.12402.1 dyn s/cm5, p = 0.016; after the shift CO 3375.0 ml/min, IQR = 3372.04402.0 ml/min, p = 0.010; TPVR 2010.5 dyn s/cm5, IQR = 1972.62351.9 dyn s/cm5, p = 0.017; MOC 7450.0 RU, IQR = 6653.37867.3 RU, p = 0.023. CONCLUSION: The extent of tension of mechanisms of self-regulation of systemic circulation, apart from characteristics of used technical means and the working regime, significantly depends on the level of emotional intelligence. With this, personnel with high emotional intellect are preferable for the work in the red zone because of lower tension of regulatory mechanisms.
新型冠状病毒感染COVID-19(冠状病毒病2019)的持续大流行对pcr实验室(进行聚合酶链反应的实验室)的活性提出了很高的要求。医务人员由于穿着个人保护手段留在红色区域,并且对其工作结果负有高度的个人责任,因此承受着过重的负担。为了提高pcr实验室人员的工作效率,提出的专业选择标准之一是情商(EQ)。目的:采用个体防护的方法,分析2019冠状病毒病疫情下不同情商pcr实验室医务人员的全身血流动力学和心率变异性状况;材料和方法:通过系统血流动力学(血压计、脉搏血氧仪)和心率变异性(心律不齐)参数评估工作期间健康风险程度和适应机制的紧张程度。对33例在pcr实验室工作1 ~ 33个月的人进行了检查。参与者在纳入研究时的平均年龄为32.4 - 1.44岁。33.7%的人EQ对应于中等水平(81120点),66.7%的人EQ对应于高水平(121168点)。结果:在轮班开始前,高EQ人员通过增加心脏活动来增加组织血供:心输出量(CO) 3938.9 ml/min,四分位差(IQR) = 3404.24230.2 ml/min,伴有血管张力降低;外周血管总阻力(TPVR) 1922.8 dyn s/cm5, IQR = 1636.52085.8 dyn s/cm5。换挡结束后,向这些代偿机制(CO = 4284.7 ml/min, IQR = 3935.44688.8 ml/min;TPVR = 1692.4 dyn s/cm5, IQR = 1584.61903.1 dyn s/cm5),心肌耗氧量增加(MOC;7917.5 RU, IQR = 7430.28811.0 RU)作为对劳动活动肌肉成分的反应而加入。在平均情商个体中,这些机制在相当大的精神压力下不太明显:轮班前CO为3722.0 ml/min, IQR = 3163.13739.0 ml/min, p = 0.013;TPVR = 2303.1 dyn s/cm5, IQR = 2058.12402.1 dyn s/cm5, p = 0.016;移位后CO 3375.0 ml/min, IQR = 3372.04402.0 ml/min, p = 0.010;TPVR 2010.5 dyn s/cm5, IQR = 1972.62351.9 dyn s/cm5, p = 0.017;MOC 7450.0 RU, IQR = 6653.37867.3 RU, p = 0.023. 结论:除了所使用的技术手段和工作制度的特点外,体循环自我调节机制的紧张程度与情绪智力水平有显著关系。因此,由于调节机制的张力较低,高情商的人员更适合在红色区域工作。

INTRODUCTION: Tobacco smoking is an important medical problem since it has a significant impact on the development and progression of chronic obstructive pulmonary disease (COPD). The components of tobacco smoke can initiate and support local and systemic inflammation with participation of monocytes and macrophages. AIM: To study molecular mechanisms associated with the impact of cigarette smoke on signaling pathways of the innate immune system in monocytes of peripheral blood. MATERIALS AND METHODS: The methods of in silico analysis was used to identify genes associated with the impact of tobacco smoke. On the basis of the data obtained, a cellular model of inflammation was created in vitro using tobacco smoke extract and monocytes of peripheral blood isolated by immunomagnetic separation. An enzyme-linked immunoassay (ELISA) kit was used to measure the concentration of tumor necrosis factor- (TNF-), interleukin-1 (IL-1) in cell supernatants, and of Toll-like receptor 4 (TLR4), ATP-binding cassette A1 (ABCA1) in homogenates of cell membranes of native monocytes and monocytes exposed to 4% tobacco smoke extract. These data were compared with the levels of TNF-, IL-1, TLR4 and ABCA1 in monocytes of peripheral blood of patients with COPD with frequent exacerbation phenotype and with obliterating atherosclerosis of lower limb arteries (OALLA). For statistical processing and visualization of the data, MedCalc 20.1.4 and R (version 4.2.2) software was used. RESULTS: Tobacco smoke influences TLR4, TNF- signaling pathways and lipid metabolism. Cigarette smoke extract enhanced the expression of proinflammatory cytokines TNF- and IL-1 in cell supernatants, increased the level of TLR4 and decreased that of ABCA1 in plasmolemma of monocytes of peripheral blood. In patients with COPD with frequent exacerbation phenotype and with OALLA, there were shown increase in the levels of proinflammatory TNF- and IL-1 cytokines in cell supernatants, increase in the level of TLR4 and reduction of the level of ABCA1 in plasmolemma of monocytes of peripheral blood compared to native monocytes of healthy individuals. CONCLUSION: Cigarette smoke enhances the production of proinflammatory TNF- and IL-1 cytokines, increases the levels of TLR4 protein and reduces the amount of ABCA1 transporter in membranes of monocytes of peripheral blood. This may partially explain the cause of the influence of cigarette smoke on development of the pulmonary and cardiovascular diseases. COPD with frequent exacerbation phenotype and OALLA are characterized by enhancement of inflammation with participation of monocytes.
吸烟是一个重要的医学问题,因为它对慢性阻塞性肺疾病(COPD)的发生和进展有重大影响。烟草烟雾成分可在单核细胞和巨噬细胞的参与下引发和支持局部和全身性炎症。目的:研究吸烟对外周血单核细胞先天免疫信号通路影响的分子机制。 材料与方法:采用计算机分析方法鉴定与烟草烟雾影响相关的基因。在此基础上,利用烟草烟雾提取物和免疫磁分离的外周血单核细胞建立体外炎症细胞模型。采用酶联免疫测定(ELISA)试剂盒测定细胞上清液中肿瘤坏死因子- (TNF-)、白细胞介素-1 (IL-1)的浓度,以及天然单核细胞和暴露于4%烟草烟雾提取物的单核细胞细胞膜匀浆中toll样受体4 (TLR4)、atp结合盒A1 (ABCA1)浓度。将这些数据与伴有频繁加重表型和下肢动脉闭塞性动脉粥样硬化(OALLA)的COPD患者外周血单核细胞TNF-、IL-1、TLR4和ABCA1水平进行比较。使用MedCalc 20.1.4和R(4.2.2版本)软件进行统计处理和数据可视化。 结果:烟草烟雾影响TLR4、TNF-信号通路及脂质代谢。香烟烟雾提取物可增强细胞上清中促炎因子TNF-和IL-1的表达,提高外周血单核细胞质膜中TLR4的水平,降低ABCA1的水平。慢性阻塞性肺疾病频繁加重型患者与OALLA患者相比,外周血单核细胞浆膜中促炎因子TNF-和IL-1水平升高,TLR4水平升高,ABCA1水平降低。 结论:吸烟可增加外周血单核细胞膜促炎因子TNF-和IL-1的产生,增加TLR4蛋白水平,降低ABCA1转运体数量。这可能部分解释了吸烟对肺部和心血管疾病发展的影响。COPD伴频繁加重表型和OALLA的特点是单核细胞参与炎症增强。

INTRODUCTION: In childhood, the immune system is actively formed, among other things, through the contact with viral and bacterial pathogens. Children over 5 years who suffer from acute respiratory diseases more than 4 times a year, are referred to the group of frequently ill children (FIC) requiring increased attention of doctors. AIM: To identify peculiarities of the autonomic regulation, metabolic, regulatory parameters of immune system cells in FIC of the primary school age. MATERIALS AND METHODS: The study involved 114 children aged 711 years. On the basis of the data of the card of childs individual development, a group of FIC was identified with recurrence rate of acute respiratory diseases more than 4 times a year (n = 28). A control group included episodically ill children (13 times a year, n = 86). The condition of the autonomic system of a child was evaluated by the data of heart rate variability using ORTO Valeo hardwaresoftware complex. The content of serotonin and catecholamines in blood lymphocytes was determined using luminescent histochemical method. Activity of succinate dehydrogenase and acid phosphatase were evaluated by cytochemical methods. RESULTS: The study of regulatory-metabolic parameters of immune cells in the group pf FIC showed reduced activity of succinate dehydrogenase (р 0.01) and reduced content of serotonin (р 0.01), and high activity of acid phosphatase (р 0.05) and catecholamines (р 0.001) in comparison with the control group. The analysis of parameters of autonomic regulation in FIC group showed predominance of parameters characterizing the sympathetic division of the autonomic nervous system and reduction of parameters characterizing the activity of the parasympathetic division (р 0.05). CONCLUSION: The results evidence a sharp imbalance between metabolic and catabolic processes in the immune system of FIC of the primary school age with the underlying predominant activity of the sympathetic nervous system. This gives the ground to study the reasonability of administration of medications and physiotherapeutic procedures for correction of the parameters of the autonomic regulation in the inter-recurrence period with the aim of improving the general adaptive capacities of FIC of the primary school age.
导读:在儿童时期,免疫系统通过与病毒和细菌病原体的接触而积极形成。5岁以上的儿童,如果每年患急性呼吸道疾病4次以上,就会被转介到需要医生更多关注的经常患病儿童(FIC)组。目的:探讨小学年龄FIC患者免疫系统细胞自主调节、代谢、调控参数的特点。 材料与方法:研究涉及114名年龄711岁的儿童。根据患儿个体发育卡资料,1组FIC患儿每年急性呼吸系统疾病复发率在4次以上(n = 28)。对照组包括发作性疾病儿童(每年13次,n = 86)。采用ORTO法雷奥软硬件复合体,通过心率变异性数据对儿童自主神经系统状况进行评估。采用荧光组织化学法测定外周血淋巴细胞血清素和儿茶酚胺含量。用细胞化学方法测定琥珀酸脱氢酶和酸性磷酸酶活性。 结果:在免疫细胞调节代谢参数研究中,与对照组相比,pf FIC组琥珀酸脱氢酶活性降低(0.01),血清素含量降低(0.01),酸性磷酸酶和儿茶酚胺活性升高(0.01)。FIC组自主神经调节参数分析显示自主神经系统交感神经分裂特征参数占优势,副交感神经分裂活性特征参数减少(p < 0.05)。 结论:结果表明,小学年龄FIC患者免疫系统代谢和分解代谢过程明显失衡,交感神经系统的活动占主导地位。这为研究药物管理和物理治疗程序的合理性提供了基础,以纠正复发间期自主调节参数,目的是提高小学年龄FIC的一般适应能力。

INTRODUCTION: Intraventricular hemorrhage (IVH) is one of the most common types of the brain damage in newborns with extremely low and very low body mass. The main source of IVH in the extremely premature infants is the germinal matrix. This is a subependymal structure of the brain consisting of poorly differentiated, randomly arranged cells, well vascularized with vessels with a poor connective-tissue support. The germinal matrix a key supplier of neurons and glial cells of the brain is unique among the brain regions for its specific rate of angiogenesis and selective vulnerability to hemorrhages during its development. Etiology and pathogenesis of IVH in premature infants are highly multifactorial and have not been fully studied. In this review, the data on the key points of the pathogenesis of IVH in premature infants are generalized. CONCLUSION: IVH is a potentially destructive disease, in the study of which a certain progress has been achieved in elucidating the causes and mechanisms of brain damage. In-depth understanding of the key points of the pathogenesis of intraventricular hemorrhage will permit to choose the optimal management tactics and develop new approaches to prevention and treatment of this pathology.
脑室内出血(IVH)是极低和极低体重新生儿最常见的脑损伤类型之一。极早产儿IVH的主要来源是生发基质。脑室管膜下结构,由低分化、随机排列的细胞组成,血管化良好,结缔组织支持差。生发基质是大脑神经元和神经胶质细胞的主要提供者,在大脑区域中具有独特的血管生成速率和发育过程中选择性出血的脆弱性。早产儿IVH的病因和发病机制是高度多因素的,尚未得到充分的研究。本文就早产儿IVH发病机制的要点进行综述。 结论:IVH是一种潜在的破坏性疾病,在阐明脑损伤的原因和机制方面取得了一定的进展。深入了解脑室内出血的发病机制将有助于选择最佳的治疗策略,并开发新的方法来预防和治疗这种病理。

INTRODUCTION: One of the commonest methods of evaluation of internalized stigma is Internalized Stigma of Mental Illness (ISMI) scale where the differences in the prevalence and perception of mental stigma in different cultures are specified. AIM: Validation of Russian version of ISMI scale and evaluation of peculiarities of perception of stigma by Russian-speaking patients with severe psychiatric disorders. MATERIALS AND METHODS: Four hundred thirty nine patients with severe psychiatric disorders (F2 and F3 according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision) were examined. The psychometric properties of the Russian version of ISMI scale were evaluated using internal consistency analysis. Exploratory and confirmatory factor analysis (EFA and CFA, respectively) were performed. To check age- and gender-related invariance, MIMIC and MIFA models were used, and discriminative power and accuracy of scoring were identified using generalized partial credit model (GPCM). The results of EFA were compared with the data obtained in the Regional Clinical Hospital (n = 120) using independent alternative version of ISMI translation into Russian. RESULTS: The internal consistency of the Russian version of ISMI questionnaire was high: Chronbachs 0.90. EFA permitted to identify 4 factors. The first factor (Demoralization, F1) combined elements corresponding to subscale 1 (Alienation) and subscale 2 (Social withdrawal) of the original version of ISMI questionnaire. The other three factors identified in this study according to the content of the items, corresponded to the remaining subscales of the original ISMI scale. In all kinds of the conducted analysis, item 14 had low factor weight. CFA confirmed the four-factor structure. In the sample, MIMIC and MIFA showed the general age- and gender-related invariance with their insufficient power. GPCM showed good characteristics of discriminative power and difficulties in choice of scoring for all factors except the fourth one (Resistance to stigma). EFA performed on the data of the alternative sample, neither could reliably reproduce the five-factor structure of the original ISMI scale due to eclectic mixing of the items of the original scale within five isolated structures. CONCLUSION: The suitability of using the internalized stigma assessment tool for the Russian-speaking population has been confirmed. The study highlights the relevance and necessity of expanding transcultural studies of psychological reactions of psychiatric patients.
简介:内化病耻感(internalized stigma of Mental Illness, ISMI)量表是评估内化病耻感最常用的方法之一,该量表明确了不同文化中心理耻感的患病率和感知差异。 目的:俄语版ISMI量表的验证及俄语重症精神障碍患者污名感特征的评价。 材料与方法:对439例重度精神障碍患者(根据《国际疾病与相关健康问题统计分类》第十版F2和F3)进行检查。采用内部一致性分析对俄文ISMI量表的心理测量特性进行评价。进行探索性和验证性因素分析(分别为EFA和CFA)。为了检查年龄和性别相关的不变性,使用了MIMIC和MIFA模型,并使用广义部分信用模型(GPCM)确定了评分的判别能力和准确性。将EFA结果与地区临床医院获得的数据(n = 120)进行比较,使用独立的ISMI翻译成俄文的替代版本。 结果:俄文ISMI问卷内部一致性高,chronbach为0.90。全民教育允许确定4个因素。第一个因素(士气低落,F1)结合了原版ISMI问卷子量表1(异化)和子量表2(社会退缩)对应的要素。本研究根据项目内容确定的其他三个因素对应于原始ISMI量表的其余子量表。在进行的各种分析中,第14项因子权重较低。CFA证实了四因素结构。在样本中,MIMIC和MIFA表现出与年龄和性别相关的一般不变性,但其效力不足。GPCM除抗污名性因子外,其余因子均表现出较好的判别能力和评分选择困难特征。对备选样本的数据进行EFA,由于原始ISMI量表的项目在五个孤立的结构中折衷混合,两者都不能可靠地再现原始ISMI量表的五因素结构。 结论:内化污名评估工具适用于俄语人群。该研究强调了扩大精神病人心理反应的跨文化研究的相关性和必要性。

To check age- and gender-related invariance, MIMIC and MIFA models were used, and discriminative power and accuracy of scoring were identified using generalized partial credit model (GPCM).

INTRODUCTION: The majority of epidemiological studies on lower extremity varicose veins (LEVV) published to date have cross-sectional character, therefore, understanding the relationships between the disease and other epidemiological variables in them is mainly based on data analysis in a short period of time and does not take into account the influence on the main parameters of functioning national health systems. It is relevant to analyze the epidemiological parameters of LEVV in the long term, taking into account the influence of the state health system in a large region of the Russian Federation. AIM: To identify changes in the distribution of LEVV in different territories of the Yaroslavl region (YaR) over 10 years (20112021). MATERIALS AND METHODS: A retrospective study of statistical parameters of the work of medical organizations of the YaR in 20112021 was conducted, namely, of the total number of attached adult population, the dynamics of the number of attached population, the total number and dynamics of the number of patients with the established diagnosis of LEVV. The weighted average value for continuous variables with a 95% confidence interval (CI) was evaluated. Heterogeneity was evaluated based on the I2 value. RESULTS: The static weighted average value of the prevalence of LEVV in Yaroslavl at the end of the year in 20112021 was 1.040% (95% CI: 1.0311.049). When analyzing the data for 20112021, the trend for a decline in the recorded prevalence of LEVV was determined. At the end of 2021, the prevalence of LEVV in Yaroslavl declined by 0.715%, in Pereslavl district by 0.466%, in Tutaev district by 0.4%, in Rostov district by 0.392%, in Rybinsk by 0.192% with high heterogeneity of data depending on the territory and period (I2 99). Besides, during the analyzed 10 years, there occurred significant changes in approaches to surgical treatment of LEVV, such as appearance of hospital-substituting technologies that have become widely used in the territory of the YaR by non-governmental medical organizations in the vast majority of cases. CONCLUSIONS: According to official data, the decline in the morbidity with LEVV in the studied territories of the YaR over 10 years (20112021) contradicts the published results of epidemiological studies. The information obtained, together with the high heterogeneity of statistical data for individual territories and periods, may indirectly indicate the low efficiency of the existing system of providing medical care to the population with LEVV.
迄今为止发表的大多数关于下肢静脉曲张(LEVV)的流行病学研究具有横断面特征,因此,了解该疾病与其中其他流行病学变量之间的关系主要基于短时间内的数据分析,而没有考虑对正常运行的国家卫生系统主要参数的影响。考虑到俄罗斯联邦大部分地区国家卫生系统的影响,长期分析LEVV的流行病学参数是有意义的。目的:确定雅罗斯拉夫尔州(YaR)不同地区10年来(20112021)LEVV分布的变化。 材料与方法:回顾性研究2011 - 21年全国医疗机构工作统计参数,即成年依附人群总数、依附人群数量动态、确诊为LEVV的患者总数和动态。对具有95%置信区间(CI)的连续变量的加权平均值进行评估。根据I2值评估异质性。 结果:雅罗斯拉夫尔市2011 - 21年末LEVV患病率的静态加权平均值为1.040% (95% CI: 1.0311.049)。在分析2011 - 21年的数据时,确定了LEVV记录患病率下降的趋势。到2021年底,雅罗斯拉夫尔地区的LEVV患病率下降了0.715%,佩列斯拉夫尔地区下降了0.466%,图塔耶夫地区下降了0.4%,罗斯托夫地区下降了0.392%,雷宾斯克地区下降了0.192%,不同地区和时期的数据具有高度异质性(1999)。此外,在所分析的10年中,LEVV的手术治疗方式发生了重大变化,例如医院替代技术的出现,在绝大多数情况下,非政府医疗机构已在叙利亚境内广泛使用。 结论:根据官方数据,在过去10年(20112021年)的研究区域中,LEVV发病率的下降与已发表的流行病学研究结果相矛盾。所获得的信息,加上个别地区和时期统计数据的高度异质性,可能间接表明现有系统为LEVV人群提供医疗服务的效率较低。
