Overcoming Barriers in Hospital-Based Health Technology Assessment (HB-HTA): International Expert Panel Consensus.

The purpose of this article is to investigate the common facilitators and barriers associated with the implementation of hospital-based health technology assessment (HB-HTA) across diverse hospital settings in seven countries. Through a two-round Delphi study, insights were gathered from a panel of 15 HTA specialists from France, Hungary, Italy, Kazakhstan, Poland, Switzerland, and Ukraine. Experts initially conducted a comprehensive review of the HB-HTA implementation in their respective countries, identifying the barriers and facilitators through descriptive analysis.

[The immune stressor effects of T-regulatory cells under infiltrative tuberculosis of lungs].

The article deals with the characteristics of sup-population composition of T-regulator: cells with suppressor activity and production of immunoregulatory cytokines suppressing immune response (IL-10, TGF-beta) in patients with infiltrative tuberculosis of lungs. It is proved that the leading role in formation of immunodepression and tuberculin anergy under infiltrative tuberculosis of lungs is played by T-regulatory, cells with phenotype CD4+CD25+Foxp3+. It is demonstrated that the immunodepression mediated by cytokine production is connected with increasing of both basal and BCG-induced secretion of IL-10 on the background of decrease of level of production of TGF-beta by mononuclear leukocytes in vitro.

[Subpopulation structure of T-regulatory cells and proliferative response of blood lymphocytes in vitro under pulmonary tuberculosis].

Subpopulation structure of T-regulatory cells and proliferative activity of blood lymphocytes in vitro in patients with different clinical forms of pulmonary tuberculosis were studied in this work. It has been shown that Trn--natural T-regulatory lymphocytes (CD4+CD25+Foxp3+) play a leading role in formation of immune suppression under infiltrative, disseminated and fibrosis-cavernous pulmonary tuberculosis. Besides, their number is increased in blood of both tuberculin-positive and tuberculin-negative patients.

[Bacteriological tests of the operative material in patients with lung tuberculosis].

64 patients with lung tuberculosis were operated on after chemotherapy course using regimens I and III. 69 patients were operated on after the treatment by DOTS/PLUS protocol. The obtained operative material was bacteriologically tested.
