Background: Kazakhstan inherited the Semashko health system model, known for the centralized adoption of rules at the Ministry of Health (MoH) level that regulate the healthcare system. In 2019 MoH established a national framework with indicators aimed at collecting qualitative and quantitative data from healthcare organizations as part of their annual self-evaluation, and biannual external evaluation by the National Research Center for Health Development (NRCHD). The purpose of this study was to pilot the MoH framework on rational use of medicines and evaluate its effects on medicine use practices in health care organizations and at the national level. Materials and methods: This cross-sectional study was conducted from October to December 2019 at 22 state-owned primary health care organizations (polyclinics) serving adults and children in Astana, Kazakhstan. Data were collected by trained surveyors visiting each organization. Data were converted to numeric values to arrive at compliance scores for each organization and analyzed to assess each organization's compliance with set indicators. Results: The evaluation showed the rational use of medicines was assessed as "excellent" (90% < compliant) in 2 organizations (9% of the sample), "good" (75–89% compliant) in 7 organizations (32%), and "satisfactory" (50–74% compliant) in 13 organizations (59%), with an average compliance rate of 71% across the sample. 22 organization-specific evaluation reports were developed by the evaluator (NRCHD) and sent to health care organizations for corrective actions. Evaluation data triggered two improvements at the national level: correction of the default setting for trade names to international nonproprietary names within the physician ordering feature of the national health information system for medicines, and adoption of a national policy that allowed the exchange of unused stocks of medicines between polyclinics. Conclusions: Using the national framework allowed the evaluator agency and healthcare organizations to identify organization-specific gaps and triggered improvements in the use of medicines.

- Abstract
Background: The aim of the study is to evaluate in vivo and in vitro effects of etanercept, a soluble tumor necrosis factor receptor, on the contractile responses of superior mesenteric artery in an experimental mesenteric ischemia and reperfusion model. Material and methods: After obtaining animal ethics committee approval, 24 Sprague eDawley rats were allocated to three groups. Control group (Gr C, n = 6) underwent a sham operation, whereas ischemia/reperfusion and treatment groups underwent 90 min ischemia and 24- h reperfusion (Gr I/R, n = 12; Gr I/RthornE, n = 6). The treatment group received 5 mg/kg etanercept intravenously at the beginning of reperfusion. At the end of reperfusion, all animals were sacrificed, and third branch of superior mesenteric artery was dissected for evaluation of contractile responses. In vitro effects of etanercept on vasocontractile responses were also evaluated. The excised ileums were analyzed under light microscope. Two- way analysis of variance following Bonferroni post hoc test was used for evaluation of contractile responses. Results: Endothelin- 1 and phenylephrine- mediated vasocontractile sensitivity were found increased in Gr I/R when compared with Gr C. Both intravenous administration and organ bath incubation of etanercept decreased the sensitivity of contractile agents for Gr I/R. Mucosal injury, lamina propria disintegration, and denuded villous tips were observed in Gr I/R, whereas the epithelial injury and the subepithelial edema were found to be milder in Gr I/RthornE. Conclusions: Etanercept can be a promising agent in mesenteric ischemic reperfusion injury as it does not only inhibit inflammation by blocking tumor necrosis factor- a in circulation but also restores vascular contractility during reflow. These findings support an unexplained recuperative effect of drug beyond its anti- inflammatory effects. (C) 2018 Elsevier Inc. All rights reserved.

Östrojen, premenapozal kadınlarda kardiyovasküler hastalıkların gelişimine karşı koruyucu etki oluştursa da bu etki diabet ve menapoz ile azalmaktadır. Östrojen damar üzerindeki etkilerini ER? ve ERß olmak üzere iki farklı reseptör aracılığı ile yapmaktadır, ancak bu reseptörlerin aracılık ettiği akut etkiler net olarak bilinmemektedir. Bu çalışmada, kontrol (K), diabetik (D), ovariektomize (O) ve ovariektomize-diabetik (OD) sıçanların torasik aortalarında östrojen reseptörlerinin gevşeme yanıtlarındaki rolü araştırılmıştır. Deney süresi 8 ve 16 hafta olarak ayrılmıştır. 8 haftalık deney hayvanlarından elde edilen endoteli intakt aorta halkaları organ banyosuna yerleştirilerek fenilefrin ile önkastırıldıktan sonra, selektif ER? agonist PPT, ERß agonist DPN ve selektif olmayan ER agonist 17ß estradiolün (E2) gevşeme yanıtları incelenmiştir. O, D ve OD gruplarında azalan, kontrol grupta PPT her iki alttipi de etkileyen doğal liganda ve ERß agonisti DPN'ye göre daha fazla gevşeme oluşturmuştur. ODE OE grubunda aynı oranda gevşeme oluşturmuştur. 16 haftalık deney gruplarında mezenterik arterlerde fenilefrinle ile elde edilen doz-yanıt eğrileri incelenmiştir. D, OE ve ODE grubun doz-yanıt eğrisinin kontrol gruba göre sola kaymiştir. Overektomize grupta doz-yanıt eğrisinin kontrol gruba göre belirgin bir farklılık göstermemiştir. OD grubun yanıtları incelendiğinde fenilefrin doz-yanıt eğrisinin sağa kaydırmıştır ancak kontrol gruba göre istatistiksel bir farklılık göstermemiştir. Mezenterik arter preparatları3 farklı ER agonisti ile 15 dakika inkübe edilerek mezenterik arter preparatlarının fenilefrinle elde edilen kontraktil yanıtlar incelenmiştir. Kontrol ve O OE gruplarda ER? agonisti PPT ve doğal ligand 17ß estradiol'ün benzer şekilde doz-yanıt eğrilerini belirgin olarak sağa kaydığı ancak ERß agonisti DPN' nin ise herhangi bir değişiklik yapmadığı saptanmıştır. D , OD gruplarda, PPT ve 17ß estradiol' ün eğrileri kontrol gruba göre daha az olmak üzere yine sağa kaydırdığı ve DPN' nin yanıtlarda bir değişiklik yapmadığı belirlenmiştir. OE ve ODE gruplarinda PPT ve 17ß estradiol yanıtlarını değiştirmediği ancak sadece DPN yanıtlarını belirgin olarak sağa kaydırdığı saptanmıştır. Çalışmamızın sonucu olarak, östrojen reseptör agonistleri fenilefrin gibi kastirici ajanlarin damar üzerindeki etkisini azaltmaktadır. ER? agonisti PPT diğer 17ß estradiol ve DPN'ye göre üstünlük göstermektedir. Hem menopozda hem diabette dışarıdan uygulanan kronik östrojen tedavisi, ER agonistlerinin özellikle ER? agonisti PPT'nin damar tonusu üzerindeki akut yararlı etkilerini maskelemektedirAnahtar Kelimeler: Aort, Diabet, Mezenterik arter, Östrojen reseptör ? ß (ER?)

In this study, we investigated the contribution of estrogen receptors (ERs) ? and ß to vasorelaxation in thoracic aorta rings from control (C), diabetic (D), ovariectomized (O) and ovariectomized-diabetic (OD) rats. The experimental duration was in 8-16 weeks.

Dose responses of Phe in D, OE and ODE groups were shifted to the left side in copmparision to Control group.

Estrogen has protective effects against cardiovascular disease in pre-menopausal women which are decreased in diabetes and menopause. ER-α and ER-β mediate estrogen effects, but acute effects on vasculature are not completely understood. In this study, we investigated the contribution of estrogen receptors (ERs) α and β to vasorelaxation in thoracic aorta rings from control (C), diabetic (D), ovariectomized (O) and ovariectomized-diabetic (OD) rats. Diabetes was induced with streptozotocin (45mg/kg,iv.) and ovariectomy was performed with bilaterally operation. The experimental duration was 8 weeks. Direct relaxant effects of the selective ER agonists 4,4′4″-(4-propyl-['H']pyrazole-1,3,5- triyl)tris-phenol (PPT), 2,3-bis(4-hydroxyphenyl)-propionitril (DPN) and the nonselective ER agonist 17β-estradiol (E2) were determined after precontracted with phenylephrine. E2 and PPT produced dosedependent relaxation (10-13M-10-7M) with a similar profile. However, the maximal relaxation (Emax) to PPT was higher than that of E2 and was diminished in aorta from O and D groups, furthermore was abolished in aorta from OD group. Emax to DPN was weakened in all aortic groups in comparision with C group. These findings suggest that there is a predominant role of ER-α on estrogen-induced vasorelaxation which is altered along with hormonal status. Hence, the ER-αagonists may offer a new treatment option for the protection of cardiovascular disease. [ABSTRACT FROM AUTHOR]
