Our objective was to assess the current and future status of HTA implementation in the MENA region by focusing on regional commonalities. Methods Preparatory discussions for the first ISPOR conference in the MENA region indicated some potentially generalizable trends of HTA roadmaps. To widen the perspective, a policy survey was conducted among conference participants by applying an HTA implementation scorecard. Discussion group members helped to validate key conclusions during and after the conference. Results Health policy experts in MENA countries would like to facilitate HTA implementation and expect significant changes with some generalizable directions in 10 years compared to the current status according. HTA capacity building has to be strengthened by more graduate and postgraduate programs. selleck compound Increased public budget and enhanced institutionalizaight © 2020 Fasseeh, Karam, Jameleddine, George, Kristensen, Al-Rabayah, Alsaggabi, El Rabbat, Alowayesh, Chamova, Ismail, Abaza and Kaló.Helicobacter pylori is one of the most widespread infections involved in the pathogenesis of chronic gastritis, peptic ulcer, and gastric cancer. Hence, there is an urgent need to develop medications against H. pylori. This study aimed to evaluate synergistic effect of Rubus crataegifolius (RF) and Ulmus macrocarpa Hance (UL) against H. pylori. Antibacterial susceptibility of each extract either separately or in combination was studied against two H. pylori standard strains and 11 clinical isolates using agar dilution method. The effect of the extracts on H. pylori inoculated Balb/c mice model was also studied using single dosing (100 mg/kg each) approach. The MIC50 of RF and UL were more than 100 and 200 µg/ml, respectively, against the tested strains. However, simultaneous treatment with RF and UL at 75 and 50 µg/ml, respectively, showed decreased viable cell number, MIC70, and at 75 µg/ml each showed synergic effect with MIC90. On H. pylori inoculated Balb/c mice model, RF and UL separately (100 mg/kg each) showed moderate anti-H. pylori effect, while simultaneous treatment of RF and UL with same dose showed significant synergistic anti-gastric effects in stomach. The results showed a significant synergistic effect of plants extract against H. pylori infection and eventually gastric mucosal damage. Our finding could be considered a valuable support in the treatment of H. pylori induced gastritis and may contribute to the development of new and safe combined herbal product as anti-H. pylori regimens.

The advantage of larger sample sizes is that negative findings become less likely and the effect estimates more precise. However, as sample sizes increase, the trials also get more expensive and time consuming while exposing more patients to drugs with unknown safety profiles. Moreover, a large sample size might yield a statistically significant effect that is not necessarily clinically relevant. Objective To assess (1) the variation in sample size and sample size calculations of antipsychotic trials in dementia, (2) the size of reported treatment effects and related statistical significance, and (3) general study characteristics that might be related to sample size. Study Design and Setting We performed a meta-epidemiological study of randomized trials that tested antipsychotics for neuropsychiatric symptoms in dementia. The trials compared conventional or atstatistically significant treatment effect, even though some suggested non-inferiority. In placebo-controlled trials of atypical drugs, longer trial duration (>6 weeks) and commercial funding were associated with higher sample size. Conclusion Sample size calculations were poorly reported in antipsychotic trials for dementia. Placebo-controlled trials of atypical antipsychotics showed large sample size fallacy while head-to-head trials were massively underpowered.

These lipoaspirate-derived cells are part of the abundant and accessible source of heterogeneous stromal vascular fraction (SVF). They are typically isolated and expanded from the SVF via adherent cell culture for at least 2 weeks and as such represent a relatively undefined population of cells. We isolated ex vivo ASC directly from lipoaspirate using a cocktail of antibodies combined with immunomagnetic bead sorting. This method allowed for the rapid enrichment of a defined and untouched ex vivo ASC population (referred to as MACS-derived ASC) that were then compared to culture-derived ASC. This comparison found that MACS-derived ASC contain a greater proportion of cells with activity in in vitro differentiation assays. There were also significant differences in the secretion levels of some key paracrine molecules. Moreover, when the MACS-derived ASC were subjected to adherent tissue culture, rapid changes in gene expression were observed. This indicates that culturing cells may alter the clinical utility of these cells. Although MACS-derived ASC are more defined compared to culture-derived ASC, further investigations using a comprehensive multicolor flow cytometry panel revealed that this cell population is more heterogeneous than previously appreciated. Additional studies are therefore required to more precisely delineate phenotypically distinct ASC subsets with the most therapeutic potential. This research highlights the disparity between ex vivo MACS-derived and culture-derived ASC and the need for further characterization.
