We randomly selected 317 patients after excluding others based on various conditions. The left ventricular mass of the 317 patients was estimated using echocardiography. Peguero–Lo Presti criteria were modified by dividing original criteria by BSA. The accuracy of the modified criteria was compared with that of the original Peguero–Lo Presti, Sokolow–Lyon, and Cornell voltage criteria.

Due to the pandemic, this production has been accelerated, which leaves a window for speculation on the method of production and safety. Pharmacists are familiar with vaccination; however, COVID-19 vaccines are still new and further work is needed to clarify many aspects, including side effects, methods of storage, and number of doses. Prioritization of vaccination has been implemented to a certain extent, but no clear strategy is available. A comprehensive overview on immunity and immunological principles for the design of COVID-19 vaccine strategies is provided in this narrative review and the current COVID-19 vaccine landscape is discussed, in addition to exploring the principles for prioritization of vaccination using data from articles available in PubMed and from health organizations. Pharmacists should have a better understanding of COVID-19 vaccines and their manufacture. This would also allow better counseling of the public on COVID 19, immunization, and explaining prioritization basis and vaccination programs.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Health risks among shift workers: the need for a multipronged approachhttps://sciendo.com/article/10.2478/abm-2021-0007ARTICLE2021-04-30T00:00:00.000+00:00Usage of herbal medicines among the elderly in a primary care unit in Hat Yai, Songkhla province, Thailandhttps://sciendo.com/article/10.2478/abm-2020-0005<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>The prevalence of chronic diseases in the elderly is high, and some use herbal medicines instead of, or together with, conventional medicine.

A vascular complication of diabetes is foot ulcers. Diabetic foot ulcers are prevalent and substantially reduce the quality of life of patients who have them. Currently, diabetic foot ulcer is a major problem for wound care specialists, and its treatment requires considerable health care resources. So far, various therapeutic modalities have been proposed to treat diabetic foot ulcers and one of them is stem cell-based therapy. Stem cell-based therapy has shown great promise for the treatment of diabetic foot ulcers. This strategy has been shown to be safe and effective in both preclinical and clinical trials. In this review, we provide an overview of the stem cell types and possible beneficial effects of stem cell transplantation therapy for diabetic foot ulcers, and an overview of the current status of stem cell research in both preclinical and clinical trial stages of treatment strategies for diabetic foot ulcers.</p> </abstract>ARTICLE2021-02-21T00:00:00.000+00:00Atypical complication in an adult patient with dengue and autoimmune hemolytic anemia: a case reporthttps://sciendo.com/article/10.2478/abm-2021-0006<abstract> <title style='display:none'>Abstract</title> <p>Severe dengue infection is associated with life-threatening complications, including severe bleeding. The bleeding tendency is typically associated with the shock phase of infection, for which blood replacement may be needed. However, repetitive blood transfusion can lead to volume overload. Administration of recombinant activated factor VII (rFVIIa) might be used to counteract bleeding without inducing volume overload. We describe the case of a patient with severe dengue infection who presented with intractable bleeding; he was initially treated with massive blood transfusions, which resulted in volume overload. He was then treated with rFVIIa to reverse the bleeding. During the second week of his hospitalization, his hematocrit dropped precipitously, and autoimmune hemolytic anemia was diagnosed. Supportive treatment was provided until recovery. Autoimmune hemolytic anemia is a rare complication in adult patients with dengue. Supportive care was effective for this atypical complication.</p> </abstract>ARTICLE2021-02-21T00:00:00.000+00:00Sensitivity and specificity of using pelvic ultrasonographic parameters combined with basal gonadotropin levels to diagnose central precocious puberty in Thai girlshttps://sciendo.com/article/10.2478/abm-2021-0004<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>The criterion standard gonadotropin-releasing hormone (GnRH) stimulation tests to diagnose central precocious puberty (CPP) are time-consuming, inconvenient, and expensive.</p> </sec> <sec><title style='display:none'>Objectives</title> <p>To determine predictive cut-off values codetermined by ultrasonographic parameters and basal gonadotropin levels in girls with premature sexual development and compare them results of criterion standard tests in a study of diagnostic accuracy.</p> </sec> <sec><title style='display:none'>Methods</title> <p>Retrospective review of hormonal investigations and ultrasonographic uterine and ovarian parameters in a consecutive sample of girls at a single center, tertiary care hospital in Bangkok, Thailand.</p> </sec> <sec><title style='display:none'>Results</title> <p>We separated data from 68 girls (age range 2–12 years) into 2 groups based on their response to a GnRH analogue agonist stimulation test.

It has been reported that both receptors can be induced by minor necrosis factor- ⃞ (TNF-α). granulocyte-colony stimulating factor (G-CSF). and vascular endothelial growth factor (VEGF) on leucocytes. However, whether these stimulations induce CD62L and CD 106 expressions on MSCs is still unknown. Thus, in the present study we investigated the effects of TNF-α. G-CSF and VEGF on CD62L and CD 160 expressions on the surface of MSCs.</p><p>Method: MSCs were isolated from rat bone marrows, and treated with different concentrations of TNF-α (0.1.1 and 10 ng/mL), G-CSF and VEGF (1.10. and 100 ng/mL) for 12 and 24 hours respectively. Then the expressions of CD62L and C'D 106 on the surface of MSCs were analyzed by flow cytometry.</p><p>Results: Immunochemistry assay showed positive CD90 but negative CD45 in the MSCs. Flow cytometry analysis suggested that TNF-α and G-CSF could induce CD62L and CD106 expressions on the surface of MSCs in a dose-dependent manner, but not in a time-dependent manner. Further, all the concentrations of VEGF had no significant effect on the CD62L and CD106 expressions.</p><p>Conclusion: CD62L and CD106 can be induced by TNF-α and G-CSF on the surface of MSCs. but not by VEGF. These findings can help improve BM-MSC migration capability and therapeutic efficiencies of MSC transplantation.</p></abstract>ARTICLE2017-02-04T00:00:00.000+00:00Percutaneous ipsilateral portal vein embolization using histoacryl glue: changing LR, resectibility rate and complicationshttps://sciendo.com/article/10.5372/1905-7415.0603.067<abstract><title style='display:none'>Abstract</title><p> Background: Liver resection has been the main strategy for treating either primary or secondary liver cancer. However, major liver resection may lead to postoperative liver failure. Portal vein embolization (PVE) is a procedure to induce hypertrophy of a liver remnant (LR) before major resection surgery. There are many variations in procedural techniques, with different advantages and disadvantages.</p><p>Objective: We studied change in liver remnant volume, resectibility rate, and complications after percutaneous ipsilateral portal vein embolization (PVE) using histoacryl glue.</p><p>Methods: Clinical data of 25 patients who underwent ipsilateral PVE were reviewed. Eighteen patients who had pre- and post- CT studies had total liver volumes (TLV) and LR volumes determined before and after the procedure using MDCT volumetry. Complications and respectability rates were recorded.</p><p>Results: All 18 patients who had pre-CT and post-CT studies had increased LR volumes. The mean of LR volumes before and after ipsilateral PVE were calculated at about 449 ml and 586 ml, which were statistically significant (p &lt;0.001). The mean enlargement of LR was 30% (range 4 to 120%). There were no deaths or serious complications. The resectabilty rate was 76%.</p><p>Conclusion: Percutaneous transhepatic ipsilateral PVE could increase the LR volumes before major hepatic resection. There were no significant complications in our study group.</p></abstract>ARTICLE2017-02-04T00:00:00.000+00:00en-us-1
