НЕЙРОПСИХОЛОГИЧЕСКИЙ СТАТУС ПАЦИЕНТОВ СО СТАБИЛЬНОЙ ИШЕМИЧЕСКОЙ БОЛЕЗНЬЮ СЕРДЦА И ФАКТОРЫ, НА НЕГО ВЛИЯЮЩИЕ

The purpose. To assess neuropsychological status of patients with stable coronary artery disease (CAD) and to determine the factors affecting it.Material and methods. 272 male patients aged 45-69 years were included in the study. Neuropsychological status of patients with coronary artery disease was assessed and presented as an integrated index.Results. The integrated index of neuropsychological status was reported to be 2 times less than those in healthy subjects matched for age (0.47 [0.35; 0.59] vs. 0.8 [0.72; 0.87, (p <0.0001)). The most significant factors affecting neuropsychological status of patients with coronary artery disease were as follows: age (p = 0.00271), number of years of education (p = 0.033), left ventricular ejection fraction (LVEF) (p = 0.018), as well as plasma triglyceride levels (TG) (p = 0.003). Conclusion. The integrated approach to the assessment of neuropsychological status in patients with CAD allows not only presenting it as a single index, but also determining the extent to which the index deviate from neuropsychological status of healthy subjects. The factors affecting neuropsychological status in patients with coronary artery disease were as follows: age, number of years of education, LVEF and plasma triglyceride levels.Цель. Оценить состояние нейропсихологического статуса пациентов со стабильной ишемической болезнью сердца (ИБС) и определить факторы, на него влияющие.Материал и методы. Обследовано 272 мужчины в возрасте 45-69 лет. Нейропсихологический статус пациента с ИБС комплексным способом был представлен в виде его интегрального показателя.Результаты. Выявлено, что интегральный показатель нейропсихологического статуса почти в 2 раза ниже данного показателя здоровых лиц того же возраста (0,47 [0,35; 0,59] и 0,8 [0,72; 0,87, (p<0,0001)). Установлено, что наиболее значимыми факторами, влияющими на нейропсихологический статус пациента с ИБС, являются возраст (p=0,00271), количество лет обучения (p=0,033), фракции выброса левого желудочка (p=0,018), а также концентрация в плазме триглицеридов (ТГ) (p=0,003).Выводы. Комплексный способ оценки нейропсихологического статуса у пациентов с ИБС позволяет оценить и представить его в виде единого показателя, а также определить степень его отклонения от статуса здоровых лиц. Факторами, негативно влияющими на состояние нейропсихологического статуса у пациентов с ИБС, являются возраст, количество лет образования, ФВ ЛЖ и концентрация в плазме крови ТГ

Synthesis and Properties of New Dihydroquercetin Derivatives

Abstract: This paper is to analyze the latest data on synthesis, structure, chemical and biological properties of flavonoid dihydroquercetin (taxifolin). Complexes including DHQ (dihydroquercetin) into cyclodextrins were obtained. These supramolecular representatives are characterized by high water-solubility, good permeability through biomembranes, prolonged action in the organism and stability while being transported in bloodflow. The use of DHQ in complex with β-cyclodextrin is more promising from the medical point of view than the use of pure DHQ. Total and partial acidylation of DHQ with acid chlorides of aliphatic, aromatic, and heterocyclic carboxylic acids, as well as selective phosphorylation with acid derivatives of trivalent phosphorus (with amides and amidethers of phosphorous acid), and aminomethylation were carried out. DHQ freely undergoes Mannich Reaction with formaldehyde and amines of various structures. The products of the reaction are isolated from the reaction mix with good yield. Isolated aminomethylated derivatives have neurotropic and antiproliferative action.The structure of all synthesized compounds was proved with the help of modern methods of analysis: spectroscopy NMR ( 1 H, 13 C) and XRS. Biological activity of dihydroquercetin modified derivatives was studied. It was found out that some of them are characterized by high cytotoxic, antitumour, and antioxidant biological activity. The inclusion complexes of dihydroquercetin and cyclodextrin were obtained. Acylation, phosphorylation and aminomethylation of dihydroquercetin was performed. The biological activity of obtained compounds was studied

A Peer-Educator Network HIV Prevention Intervention Among Injection Drug Users: Results of a Randomized Controlled Trial in St. Petersburg, Russia

We evaluated the efficacy of a peer-educator network intervention as a strategy to reduce HIV acquisition among injection drug users (IDUs) and their drug and/or sexual networks. A randomized controlled trial was conducted in St. Petersburg, Russia among IDU index participants and their risk network participants. Network units were randomized to the control or experimental intervention. Only the experimental index participants received training sessions to communicate risk reduction techniques to their network members. Analysis includes 76 index and 84 network participants who were HIV uninfected. The main outcome measure was HIV sero-conversion. The incidence rates in the control and experimental groups were 19.57 (95 % CI 10.74–35.65) and 7.76 (95 % CI 3.51–17.19) cases per 100 p/y, respectively. The IRR was 0.41 (95 % CI 0.15–1.08) without a statistically significant difference between the two groups (log rank test statistic X(2) = 2.73, permutation p value = 0.16). Retention rate was 67 % with a third of the loss due to incarceration or death. The results show a promising trend that this strategy would be successful in reducing the acquisition of HIV among IDUs
