[Social networks as a space of communication on health issues].

Social media is bringing a new dimension to healthcare as it offers an environment through which the public, patients, and healthcare professionals can report health issues with the possibility of potentially improving health outcomes. Social networks are a powerful tool that ensures cooperation between users and is a mechanism of social interaction for a wide range of people. Although the use of social networks for communication in the field of health has a number of advantages, the exchange of information must be monitored for quality and reliability, as well as to preserve the confidentiality of users.

[Use of extracorporeal membrane oxygenation for pulmonary haemorrhage after pulmonary endarterectomy]. / Primenenie ékstrakorporal'noi membrannoi oksigenatsii pri legochnom krovotechenii posle legochnoi éndarteréktomii.

Pulmonary haemorrhage is one of the most severe complications of pulmonary endarterectomy. To the most effective methods of combating this potentially fatal complication belongs extracorporeal membrane oxygenation (ECMO). In this article we describe a clinical case report regarding intraoperative use of central veno-arterial ECMO for pulmonary haemorrhage following thromboendarterectomy from the pulmonary arteries. According to the data of some authors, long-term ECMO support (for more than 4 days) may lead to such severe consequences as rethrombosis of pulmonary arteries and impairment of cerebral circulation. In our case we managed to avoid such complications, taking into consideration that the duration of ECMO amounted to 21 days. Resulting from the carried out comprehensive therapeutic measures by the time of discharge from hospital, a significant decrease in pulmonary artery pressure was achieved, with events of residual pulmonary hypertension.

[Patient's way from acute pulmonary embolism to chronic thromboembolic pulmonary hypertension: diagnostic and treatment options].

Сhronic thromboembolic pulmonary hypertension (CTEPH) is a serious, under - diagnosed but potentially curable complication of pulmonary embolism (PE) due to medicine advancements. Lack of specific symptoms and signs makes its diagnosis challenging, requiring clinicians to be ready to suspect its presence in patients with dyspnea of unknown origin or persistent symptoms after the pulmonary embolism event. The success of the treatment of this disease depends entirely on early diagnosis. The complexity of the differential diagnosis is due to the problematic aspects including the lack of doctors' awareness of both the pathology itself and the possibilities of its modern treatment. Recently, in our country, the problem of the availability of expert centers with sufficient experience in providing highly specialized medical care to this rather difficult category of patients who need specific therapy has become very actual. The aim of this review is to provide contemporary information about epidemiology, pathophysiology, and clinical features of treating patients with CTEPH, and also, to increase awareness of potential PE→CTEPH transformation. In the article a 4-year - period of experience of the Meshalkin National Medical Research Center on management of CTEPH patients has been presented.

[Radiofrequency Pulmonary Artery Ablation for Treatment of Residual Pulmonary Hypertension After Pulmonary Endarterectomy].

OBJECTIVE: to assess the safety and efficiency of radiofrequency pulmonary artery ablation for treatment of residual pulmonary hypertension after pulmonary endarterectomy. MATERIAL AND METHODS: Radiofrequency pulmonary artery denervation (PADN) was performed in 16 patients (10 men, mean age 39 years [26; 51]). Indication for PADN was mean pulmonary artery pressure (PAP) >25 mm Hg with absence of proximal pulmonary artery lesion according to computer tomography. PADN procedure was performed with nonfluoroscopic 3D navigation system. RESULTS: After PADN mean PAP decreased from 37.3 mm Hg [29; 38] to 24.6 mm Hg [17; 30] (p=0.01); pulmonary vascular resistance decreased from 672 dyn·s·c -5 [387; 566] to 386 dyn·s·c -5 [155; 449] (р=0.02); cardiac output increased from 3.4 l / min [3.2; 3.4] to 3.5 l / min [3.2; 4.0] (p=0.4); 6­minute walk test distance increased from 427 meters [352; 510] to 447 meters [370; 525] (p=0.16), respectively. CONCLUSION: Initial results allow to assume that radiofrequency pulmonary artery denervation combined with optimal medical therapy may take its rightful place in the treatment of this category of patients.

[The action of the alkanol ammonium salts of aroxyacetic acids on the thrombocyte aggregation process]. / Deistvie alkanolammonievykh solei aroksiuksusnykh kislot na protsess agregatsii trombotsitov.

Tris(2-hydroxyethyl)ammoniates of ezo-substituted aroxyalkane-carboxylic acids were examined for their effects on in vitro platelet aggregation under the influence of biogenic amines, as well as in lipid peroxidation. Hemocoagulation was evaluated in vivo. The agents tested were demonstrated no be a promising class of platelet aggregation inhibitors. They possess antioxidative effects, by reducing the level of malonic dialdehyde in induced hyperaggregation and the rate of lipid peroxidation. When given to animals, the agents decreased the activity of prothrombin factors.

[A comparison of the effect of tranquilizers in experiments and clinical practice]. / Sravnenie éffekta trankvilizatorov v éksperimente i klinicheskoi praktike.

Experimental and clinical study of the analgesic effects of mebicar and benzodiazepine series tranquilizers (sibazon and chlozepid) and their combinations with non-narcotic analgesics (amidopyrin, pyranal) or local anesthetic lidocaine has demonstrated a more marked effect of benzodiazepine derivatives on pain sensitivity thresholds as against mebicar. Tranquilizer combinations with other analgesics helped define the optimal premedication variants: benzodiazepine derivative augment analgesic activity whereas mebicar potentiates lidocaine effect.

It was shown in experiments on rabbits that dimethoxyphosphates of rare-earth elements injected intravenously displayed a marked anticoagulant activity. The highest effect was produced by compounds of neodymium, holmium, terbium, europium, thulium, dysprosium, and erbium.

[Penetration and binding strength of cadmium and its complexes with dithiols in cells]. / Proniknovenie i prochnost' sviazyvaniia kadmiia i ego kompleksov s ditiolami v kletkakh.

It was shown in experiments with three types of cells (dog red cells, hepatic cells of newborn Wistar rats, and culture of the renal epithelium of Vero monkeys) that cadmium in complexes with dimercaptoethanol penetrates the cells in an 8-33-fold greater amounts than free cations of metal. Unithiol increases cadmium penetration in the cells by 1.6-3 times only. The strength of cadmium binding with dimercaptopropranolol in the cells is greater than that with unithiol and free cations. Albumin limits penetration of free cations of cadmium and of complexes with dimercaptothiol to a greater degree than that of cadmium complexes with unithiols. The reasons for the differences revealed are discussed.
