PReS-FINAL-2041: Macrophage activation syndrome in the children with systemic juvenile idiopathic arthritis during the course of tocilizumab

Background Trauma exposure and posttraumatic stress disorder (PTSD) are common among individuals with a mental disorder, but symptoms often go undetected and untreated. Methods The aim of this study was to determine the prevalence of PTSD among a large sample of adults with psychiatric diagnoses and to establish factors associated with symptoms going undetected. Participants were 1,946 adults recruited by the National Centre for Mental Health. Structured interviews and validated self-report questionnaires were used to ascertain clinical and demographic information for analysis. Results The prevalence of participants screening positive for PTSD that had not been detected by clinical services was 13.9% [12.4–15.5%, 95% confidence interval]). Factors associated with undetected PTSD were female gender, younger age of first contact with psychiatric services, and lower household income. Especially, poor rates of detection were observed after traumatic events, such as child abuse and sexual assault. Conclusions Our findings demonstrate the need for routine assessment of trauma histories and symptoms of PTSD among individuals with anymental disorder

The Role of Genetic Polymorphism in the Formation of Arterial Hypertension, Type 2 Diabetes and their Comorbidity

Background: Hereditary component plays a significant role in the formation of insulin resistance (IR) - one of the pathogenetic links of arterial hypertension (AH) and type 2 diabetes mellitus (DM2). However, the genetic predisposition to IR can not be realized and does not manifest itself clinically in the absence of appropriate factors of the environment (excessive nutrition, low physical activity, etc.). Objective: The review summarizes the results of studies which describe the contribution of genetic polymorphism to the formation and progression of AH, DM2 and their comorbidity in various populations. Results: In many studies, it has been established that genetic polymorphism of candidate genes is influenced by the formation, course and complication of AH and DM2. According to research data, the modulating effect of polymorphism of some genetic markers of AH and DM2 on metabolism and hemodynamics has been established. The results of numerous studies have shown a higher frequency of occurrence of AH and DM2, as well as their more severe course with adverse genetic polymorphisms. At the same time, the role of genetic polymorphism in the formation of AH and DM2 differs in different populations. Conclusion: Contradictory data on the influence of gene polymorphisms on the formation of AH and DM2 in different populations, as well as a small number of studies on the combined effects of several polymorphisms on the formation of comorbidity, determine the continuation of research in this direction

The paper presents the basic principles of providing medical, including rheumatology, care in the republic. It gives data on the issues of providing SLE patients with medicines in outpatient and inpatient settings. It also analyzes trends in the incidence of SLE in the population of Kazakhstan in 2012 to 2017. There were 4,448 SLE patients, including 3,986 women; a comparative analysis of indicators demonstrated a 62.8% increase in the incidence of SLE from 2012 to 2017. The purpose and objectives of the registry of patients with SLE were substantiated.Conclusion. An analysis of morbidity rates suggests that SLE remains to be significant in the republic. The incidence of SLE has been noted to increase in the period from 2012 to 2017; there is a female preponderance (89.6%). The application of the SLE registry in clinical practice will be able to improve the diagnosis of the disease in the early stage and to prevent possible complications. Цель исследования – анализ оказания медицинской, в том числе ревматологической, помощи в Казахстане, изучение показателей заболеваемости и разработка регистра пациентов с системной красной волчанкой (СКВ).Материал и методы.

Thermally Responsive Amphiphilic Conetworks and Gels Based on Poly(N‑isopropylacrylamide) and Polyisobutylene

Novel amphiphilic conetworks (APCN) consisting of thermoresponsive poly(N-isoproplyacrylamide) (PNiPAAm) cross-linked by hydrophobic methacrylate-telechelic polyisobutylene (MA-PIB-MA) were successfully synthesized in a broad composition range. The resulting PNiPAAm-l-PIB conetworks (“l” stands for “linked by”) were obtained by radical copolymerization of NiPAAm with MA-PIB-MA in tetrahydrofuran, a cosolvent for all the components. Low amounts of extractables substantiated efficient network formation. The composition dependent two glass transition temperatures (Tg) by DSC analysis indicate microphase separation of the cross-linked components without mixed phases. It was found that the PNiPAAm-l-PIB conetworks are uniformly swellable in both water and n-hexane; i.e., these new materials behave either as hydrogels or as hydrophobic gels in aqueous or nonpolar media, respectively. The uniform swelling in both polar and nonpolar solutes indicates cocontinuous (bicontinuous) phase morphology. The equilibrium swelling degrees (R) depend on composition, that is, the higher the PIB content, the lower the R in water and the higher in n-hexane. The PNiPAAm phase keeps its thermoresponsive behavior in the conetworks as shown by significant decrease of the swelling degree in water between 20 and 35 °C. The lower critical solubility temperature (LCST) values determined by DSC are found to decrease from 34.1 °C (for the pure PNiPAAm homopolymer) to the range of 25–28 °C in the conetworks, and the extent of the LCST decrease is proportional with the PIB content. Deswelling-swelling, i.e., heating–cooling, cycle indicates insignificant hysteresis in these new thermoresponsive materials. This indicates that PNiPAAm-l-PIB conetworks with predetermined and thermoresponsive swelling behavior can be designed and utilized in several advanced applications on the basis of results obtained in the course of this study

Angiogenesis inhibitors in the treatment of prostate cancer

Prostate cancer remains a significant public health problem, with limited therapeutic options in the setting of castrate-resistant metastatic disease. Angiogenesis inhibition is a relatively novel antineoplastic approach, which targets the reliance of tumor growth on the formation of new blood vessels. This strategy has been used successfully in other solid tumor types, with the FDA approval of anti-angiogenic agents in breast, lung, colon, brain, and kidney cancer. The application of anti-angiogenic therapy to prostate cancer is reviewed in this article, with attention to efficacy and toxicity results from several classes of anti-angiogenic agents. Ultimately, the fate of anti-angiogenic agents in prostate cancer rests on the eagerly anticipated results of several key phase III studies
