Mefenamic acid is a potent analgesic possessing both anti-inflammatory and antipyretic properties. It is completely absorbed one to two hours after intake. Majority of patients however, expect relief of pain within 15 minutes. A new oral mefenamic acid containing sodium lauryl sulfate with a dissolution rate of 98 per cent in 15 minutes has been introduced. This phase 4 clinical trial was conducted to evaluate the onset of pain relief upon administration of mefenamic acid 500 mg combined with sodium lauryl sulfate. The study was an open, noncomparative clinical trial. Physicians all over the Philippines were asked to fill up a standard 3-page case report form. A total of 2,617 patients with a mean age of 36 years were enrolled. Forty two per cent were males and fifty eight per cent were females. Seventy per cent of patients took the drug every 6-8 hours. Majority (78.38%) reported complete resolution of pain (54.3%) of which occurred within 15 minutes, increasing to 84.93% within 30 minutes). Only 1.12 per cent showed no response. Forty one patients (1.57%) reported minor adverse reactions, majority of whose conditions improved with withdrawal of the drug. The overall assessment of clinical response was very good to excellent in 77.66 percent of patients.(Author)

2.Data Sharing: a New Editorial Initiative from the International Committee of Medical Journal Editors. Implications for the Editors' Network.
Korean Circulation Journal 2017;47(3):307-313
The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship-emphasizing the importance of responsibility and accountability-, have been proposed. This year a new editorial initiative to foster sharing of clinical trial data has been launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and Editors of the Editors' Network of the European Society of Cardiology.

BACKGROUND AND OBJECTIVE: The characteristics of human hematopoietic stem cells are conditioned by the microenvironment of the bone marrow, where they interact with other cell populations, such as mesenchymal stem cells and endothelial cells; however, the study of this microenvironment is complex. The objective of this work was to develop a 3D culture system by magnetic levitation that imitates the microenvironment of human HSC. METHODS AND RESULTS: Human bone marrow-mesenchymal stem cells, umbilical cord blood-hematopoietic stem cells and a non-tumoral endothelial cell line (CC2811, Lonza®) were used to develop organotypic multicellular spheres by the magnetic levitation method. We obtained viable structures with an average sphericity index greater than 0.6, an average volume of 0.5 mm3 and a percentage of aggregation greater than 70%. Histological studies of the organotypic multicellular spheres used hematoxylin and eosin stains, and an evaluation of vimentin expression by means of immunohistochemistry demonstrated an organized internal structure without picnotic cells and a high expression of vimentin. The functional capacity of human hematopoietic stem cells after organotypic multicellular spheres culture was evaluated by multipotency tests, and it was demonstrated that 3D structures without exogenous Flt3L are autonomous in the maintenance of multipotency of human hematopoietic stem cells. CONCLUSIONS: We developed organotypic multicellular spheres from normal human cells that mimic the microenvironment of the human hematopoietic stem cells. These structures are the prototype for the development of complex organoids that allow the further study of the biology of normal human stem cells and their potential in regenerative medicine.
