Computed tomography volumetry is the standard method for preoperative estimation of liver volume. Despite the development of various software, the trend towards discrepancy in the calculation of liver volume compared with any of the methods and intraoperative graft weight remains. The aim of the study was to optimize the manual method of CT volumetry donor’ liver, determine its accuracy and compare it with the standard method. Material and methods. A single-center prospective study including data from 60 liver donors who underwent computed tomography, CT volumetry and liver transplantation at the National Scientific Surgery Center named after A.N. Syzganov for the period 2018-2022. Results. The Pearson correlation between the right liver lobe volume estimated by the standard method and the graft weight was 0.730 (p<0.01), the Pearson correlation between the liver volume calculated by the optimized method (-10 HU) and the graft was 0.757 (p<0.01), and the correlation between the optimized method (-20 HU) and graft weight – 0.860 (p<0.01). The Pearson correlation coefficient of the optimized method (-20 HU) is statistically significantly higher than the correlation coefficient of the standard manual method (p=0.026), the difference between the correlation coefficient of the optimized method (-10 HU) and the standard one is statistically insignificant (p=0.375). The degree of discrepancy between the optimized method (-20 HU) was 8.4%, manual method - 12.7%. There is a statistically significant difference between the degree of discrepancy between the standard manual and optimized method (-20 HU) (p=0.029). Conclusions. Optimization of the manual CT volumetry method with a decrease in the liver density threshold by 20 HU demonstrated a statistically significantly high correlation coefficient with the graft weight, and also significantly reduced the degree of discrepancy.
计算机断层扫描体积测量是术前估计肝脏体积的标准方法。尽管各种软件的发展,肝脏体积的计算与任何一种方法和术中移植物重量的差异趋势仍然存在。本研究的目的是优化人工CT供体肝脏体积测量方法,确定其准确性,并与标准方法进行比较。材料和方法。这是一项单中心前瞻性研究,包括2018-2022年期间在以A.N. Syzganov命名的国家科学外科中心接受计算机断层扫描、CT体积测量和肝移植的60名肝脏捐赠者的数据。结果。标准方法计算的右肝叶体积与移植物重量的Pearson相关性为0.730 (p<0.01),优化方法计算的肝体积(-10 HU)与移植物重量的Pearson相关性为0.757 (p<0.01),优化方法计算的肝体积(-20 HU)与移植物重量的Pearson相关性为- 0.860 (p<0.01)。优化方法的Pearson相关系数(-20 HU)显著高于标准手工方法的相关系数(p=0.026),与标准方法的相关系数(-10 HU)差异无统计学意义(p=0.375)。优化方法(-20 HU)与人工方法(- 12.7%)的差异程度为8.4%。标准手册与优化方法的差异程度有统计学意义(-20 HU) (p=0.029)。结论。手动CT容积法优化后,肝脏密度阈值降低20 HU,与移植物重量的相关系数具有统计学意义上的高,差异程度也显著降低。

Purpose of the study: comparative assessment of hematological and autoimmune status of patients with Graves’ disease (GD). Materials and methods. 43 GD patients aged between 19 and 64 years, 26 of which were women and 17 were men, have been examined. Assessment of hemograms of examined patients helped to reveal anemia in 28(65.1%) examined patients (group I). In 15 (34.9%) patients (group II) anemia was not detected. Mild anemia was diagnosed in 25 (89.3%), moderate anemia – in 3 (10.7%) patients. Hemoglobin, hematocrit, erythrocyte count and erythrocyte indices MCV, MCH, MCHC, serum Fe and ferritin status was chaecked in clinical analysis. The immune status was assessed by the level of CD3+, CD4+, CD8+, CD19+, CD4+/CD8+, CEC, Ef, TSHRAb and hormonal status by the level of TSH, T4 free. Results. Microcytic anemia was determined in 15 (53.6%) patients, normocytic - in 12 (42.8%), macrocytic - in 1 (3.5%) patient due to volume of erythrocytes’ MCV. According to morphological criteria of МСН (mean content of hemoglobin in erythrocyte) anemia hypochromic type of anemia was noted in 15 (53.6%) patients, normochromic - in 12 (42.8%), hyperchromic - in 1 (3.5%) patient. In 15 (53.6%%) patients in the group I microcytic - hypochromic anemia was diagnosed, which is characteristic for iron-deficient anemia; in 12 (42.8%) patients was verified normocyticnormochromic anemia, which has morphological parameters of anemia of chronic diseases and in 1 (3.5%) patient macrocytic-hyperchromic anemia. Comparative assessment of HGB level and indicators of iron metabolism in GD patients with anemia detected decreasing of HGB by 20%, serum Fe by 20%, ferritin by 29% compared to the corresponding control values. More pronounced depletion of the iron depot (ferritin) due to the fact that the development of anemia is preceded by a “latent iron deficiency”, an indicator of which is ferritin. Conclusions. GD is characterized by high frequency of anemia (65.1%), mostly mild form (89.3%), microcytichypochromic (53.6%), characteristic of iron deficiency anemia. The severe hematological disorders, detected among GD patients with anemia are accompanied by deep autoimmune changes and hyperfunction of the thyroid gland.
研究目的:比较评估Graves病(GD)患者的血液学和自身免疫状态。材料和方法。43例GD患者,年龄19 ~ 64岁,其中女性26例,男性17例。ⅰ组28例(65.1%)检测到贫血,ⅱ组15例(34.9%)未检出贫血。轻度贫血25例(89.3%),中度贫血3例(10.7%)。临床分析检查血红蛋白、红细胞压积、红细胞计数及红细胞指标MCV、MCH、MCHC、血清铁、铁蛋白状态。以CD3+、CD4+、CD8+、CD19+、CD4+/CD8+、CEC、Ef、TSHRAb水平评价免疫状态,以TSH、T4 free水平评价激素状态。结果。根据红细胞MCV的测定,小细胞性贫血15例(53.6%),常细胞性贫血12例(42.8%),巨细胞性贫血1例(3.5%)。根据МСН(红细胞平均血红蛋白含量)的形态学标准,低色型贫血15例(53.6%),正色型贫血12例(42.8%),高色型贫血1例(3.5%)。15例(53.6%)的患者被诊断为小细胞-低色素贫血,这是缺铁性贫血的特征;12例(42.8%)确诊为正细胞-正色性贫血,具有慢性病贫血的形态参数;1例(3.5%)确诊为巨细胞-高色性贫血。GD合并贫血患者HGB水平及铁代谢指标对比评估发现,与相应对照值相比,HGB下降20%,血清铁下降20%,铁蛋白下降29%。更明显的铁库(铁蛋白)耗竭是由于在贫血发生之前存在“潜在缺铁”这一事实,铁蛋白是其指标之一。结论。GD的特点是高频率贫血(65.1%),多为轻度贫血(89.3%),微红细胞染色(53.6%),以缺铁性贫血为特征。GD合并贫血患者中发现的严重血液学疾病伴有深层自身免疫改变和甲状腺功能亢进。

Interrupted inferior vena cava is a rare condition that can occur either in isolation or in combination with asplasia or polysplasia syndromes. Abnormal development of systemic veins is closely related to atrial situs. In levocardia, there are signs of abdominal organ inversion, which is called visceral situs. The present paper describes a clinical case of a infant with a large interventricular septal defect combined with interrupted inferior vena cava with azygous continuation of visceral situs ambiguous heterotaxy. The defect plasty was performed at the operation, and the complete venous cannulation required for artificial circulation was performed by the correctly chosen method of drainage of the superior venous system - through the auricle of the right atrium and the inferior venous system - through a separate hepatic vein cannulation, with a good clinical result.
下腔静脉中断是一种罕见的疾病,既可以单独发生,也可以与发育不全或多晶体综合征合并发生。系统静脉的异常发育与心房位置密切相关。左心瓣膜有腹部脏器倒置的征象,称为内脏位置。本文报告一例婴幼儿大面积室间隔缺损合并下腔静脉中断并脏器位置不明确异位的奇异延续的临床病例。术中进行缺损成形术,正确选择上静脉系统经右心房耳廓、下静脉系统经单独肝静脉插管引流的方法,完成人工循环所需的全静脉插管,取得了良好的临床效果。

The aim of the study is to determine the levels of the S100B protein in patients with ischemic stroke and evaluate its relationship with the size of brain tissue damage, stroke severity, and clinical outcomes. Materials and methods.The study included 113 patients with acute ischemic stroke, hospitalized within the first day after its onset and subjected to invasive treatment. 101 men and 12 women were examined, including 32 at the age of 50-60, 64 at the age of 61-70, 17 at the age of 71-80. parameters and degree of functional deviations according to the NIHSS scale. Results. The content of S100B during the initial determination on average for the group significantly exceeded the level determined in the control by 3.22 times (p=0.025). There was a direct dependence of the content of S100B on the size of the stroke. A moderate increase in the indicator on the 3rd day relative to the determined one on the 1st day and a decrease on the 7th day after the development of the stroke were revealed. There was no significant dependence of S100B content on the presence of comorbidities. The influence of the studied parameter on the degree of neurological deficit was determined only in patients with a large stroke size.

Objective: To compare the immediate outcomes of thoracoscopy and median sternotomy in patients undergoing ventricular septal defect repair. Materials and мethods. We analyzed 59 patients diagnosed with VSD who were operated on at the SCCCST from 2012 to 2021. All patients were divided into two groups: group 1 included patients in whom thoracoscopic access was used (n=27), group 2 included the method of complete median sternotomy (n=32). Results. There were no statistically significant differences in complications in the postoperative period and no in-hospital mortality. The duration of the procedure and the duration of cardiopulmonary bypass in the thoracoscopy group were longer than in the sternotomy group. Blood loss during and after surgery was lower in the thoracoscopy group than in the sternotomy group. Hence, less blood and plasma transfusion was required in the thoracoscopy group than in the sternotomy group. The length of stay in the intensive care unit, the time spent on mechanical ventilation, bed days after surgery, the use of analgesics were statistically lower in the thoracoscopy group than in the sternotomy group. It should be noted that the length of the skin incision in patients in the thoracoscopy group was significantly less than in the second group. Conclusion. Thoracoscopic approach for VSD correction is an effective and low-traumatic method that does not increase the risk of surgical complications. Routine use of this technique requires a study on a larger sample of patients.
目的:比较胸腔镜与胸骨正中切开术治疗室间隔缺损的直接疗效。材料和мethods。我们分析了2012年至2021年在SCCCST接受手术的59例诊断为室间隔功能障碍的患者。所有患者分为两组:第一组采用胸腔镜入路(n=27),第二组采用胸骨正中完全切开术(n=32)。结果。两组术后并发症及住院死亡率无统计学差异。胸腔镜组手术时间和体外循环时间均长于开胸术组。胸腔镜组术中及术后出血量均低于开胸术组。因此,胸腔镜组比开胸术组需要更少的血液和血浆输血。在重症监护病房的住院时间、机械通气时间、术后卧床天数、镇痛药的使用方面,胸腔镜组明显低于开胸术组。需要注意的是,胸腔镜组患者皮肤切口的长度明显小于第二组。结论。胸腔镜入路矫正室间隔缺损是一种有效且低创伤的方法,不会增加手术并发症的风险。常规使用这种技术需要对更大的患者样本进行研究。

Many countries have actively implemented reforms over the last two decades to incrеase the productivity of their healthcare systems and the effectiveness of treatment and prevention activities. And the classical indicators of hospital performance such as the use of hospital beds and the quality of hospital care are the main indicators of good management in a hospital. Material and methods. The object of the study is the medical and statistical performance indicators of the surgical department and the surgical day hospital of the multidisciplinary hospital in Almaty for 5 years (2017–2021). As a source of information, an electronic database of the statistical department of the hospital was used. Medical statistical analysis was applied as a method of study. This type of study is a cross-sectional study based on a retrospective descriptive analysis of official statistics. Results. In terms of dynamics, the structure of those treated in the surgical department does not change. However, there is a significant decrease in the amount of planned surgical pathology compared to the slight drop in hospitalization (a decrease of -40%), possibly due to a decrease in the volume of government orders (a decrease of -43.4%). Within the framework of the state order, the indicator of the average length of stay of a patient in a hospital, in general, tends to decrease from 8,5 in 2017 to 8,2 in 2021. A higher level of surgical activity in the surgical department (76,4% vs. 62,6% in surgical departments in 2021), a lower postoperative complication rate (0,2% vs. 0,3%), and a lower postoperative mortality (0,7% vs. 1,1%) were stated as positive indicators of surgical service. In 2021, the frequency of emergency operations in the surgical department was roughly the same, at 19,1%; the total share of outpatient surgery (for all profiles) in the structure of all surgery was 11,3%. Conclusion. The identified deterioration in the use of hospital beds in the surgical department (decrease in bed turnover, increase in the average duration of one case of hospitalization, decrease in the planned number of bed days) requires improvement of the planning and control system for hospitalization. Perhaps this problem is relevant for many multidisciplinary hospitals
在过去二十年中,许多国家积极实施了改革,以提高其卫生保健系统的生产力以及治疗和预防活动的有效性。而病床使用率、医院护理质量等医院绩效的经典指标是衡量医院管理好坏的主要指标。材料和方法。研究对象为阿拉木图多学科医院外科科室和外科日间医院5年(2017-2021年)的医疗和统计绩效指标。作为信息来源,使用了医院统计部门的电子数据库。采用医学统计分析方法进行研究。这种类型的研究是基于官方统计数据的回顾性描述性分析的横断面研究。结果。在动力学方面,那些在外科治疗的人的结构没有改变。然而,与住院治疗的轻微下降(下降了-40%)相比,计划的手术病理数量明显减少,这可能是由于政府订单数量的减少(下降了-43.4%)。在国家秩序框架内,病人在医院的平均住院时间指标总体上有从2017年的8.5降至2021年的8.2的趋势。较高水平的外科手术活动量(2021年为76.4%对62.6%)、较低的术后并发症发生率(0.2%对0.3%)和较低的术后死亡率(0.7%对1.1%)被认为是手术服务的积极指标。2021年,外科急诊手术的频率大致相同,为19.1%;门诊手术在所有手术结构中的总份额为11.3%。结论。已查明的外科病床使用情况恶化(病床周转率减少、平均每例住院时间增加、计划住院天数减少)要求改进住院计划和控制制度。也许这个问题与许多多学科医院有关

Without the development of clinical toxicology, the population is doomed to suffer great losses in the event of the use of chemical weapons or man-made disasters, since the national health structure will not be able to provide the necessary symptomatic and antidote care to the affected people. The development of clinical toxicology is necessary today because of the threat of latent methods of chemical attack, when prevention and chemical control structures become ineffective and the consequences of poisoning with an unknown poisoning agent have to be dealt with.
如果不发展临床毒理学,在使用化学武器或人为灾难的情况下,人民注定要遭受巨大损失,因为国家卫生机构将无法向受影响的人民提供必要的对症治疗和解毒剂治疗。临床毒理学的发展在今天是必要的,因为潜在的化学攻击方法的威胁,当预防和化学控制结构失效时,未知中毒剂中毒的后果必须处理。

Since the beginning of the spread of coronavirus infection in the world, the number of infected has exceeded 102.5 million people, and more than 2.2 million people have died. In Kazakhstan, according to the world statistics of COVID-19, the 59th place in the number of detected cases of COVID-19 and the 68th place in deaths from coronavirus was noted. The vast majority of patients with COVID-19 have a mild or moderate illness, but 5% of those with a critical course of the disease require treatment in an intensive care unit. The length of stay in the intensive care unit averages 10.8 days, however, in 22.7% of patients, the duration of treatment in the ICU exceeds 30 days. In order to improve treatment outcomes, many clinics use a team work methodology that requires a sufficient number of highly qualified medical personnel. However, due to the shortage of personnel in intensive care units, measures are being taken to retrain medical personnel of other specialties. At the same time, short training courses do not always improve the results of treatment in a high quality and lead to a deterioration in the results of most patients.
自冠状病毒感染开始在全球传播以来,感染人数已超过1.025亿人,死亡人数超过220万人。根据COVID-19的世界统计数据,哈萨克斯坦在COVID-19发现病例数上排名第59位,在冠状病毒死亡人数上排名第68位。绝大多数COVID-19患者病情轻微或中度,但5%的危重期患者需要在重症监护病房接受治疗。重症监护病房的平均住院时间为10.8天,但22.7%的患者在重症监护病房的治疗时间超过30天。为了改善治疗效果,许多诊所采用团队合作的方法,需要足够数量的高素质医务人员。但是,由于重症监护室人员短缺,正在采取措施对其他专业的医务人员进行再培训。同时,短期的培训课程并不总是能高质量地提高治疗效果,并导致大多数患者的治疗效果恶化。

Stroke is the second leading cause of death and the third leading cause of disability globally. This literature review described risk factors and diagnostic aspects of ischemic stroke prevention. Carotid stenosis and occlusion is a treatable cause of ischemic stroke, which can be diagnosed by duplex scanning of the brachiocephalic arteries. The reasons for the low effectiveness of preventive measures for ischemic stroke are the incomplete collection of anamnesis for risk factors that affect the clinical prognosis, the low use of modern diagnostic methods by primary health care general practitioners in the screening of patients.
中风是全球第二大死因和第三大致残原因。本文献综述描述了缺血性卒中预防的危险因素和诊断方面。颈动脉狭窄和闭塞是缺血性脑卒中的可治疗原因,可通过头臂动脉的双工扫描诊断。缺血性脑卒中预防措施有效性低的原因是对影响临床预后的危险因素的记忆收集不完整,初级卫生保健全科医生在筛查患者时现代诊断方法的使用率低。
