Distribution of ABO and D antigen expression in Yogyakarta, Java Island: a pioneer large-scale study in Indonesia.

Objective: Here, we sought to report ABO and D antigen distribution in blood donors from Yogyakarta, Java Island, Indonesia. Phenotype data (ABO/D) from donors who donated blood between January 1, 2018, and December 31, 2023, at the Yogyakarta Blood Donor Unit were extracted from the blood donor registry, and phenotype frequency was calculated subsequently.

Results: In the 245,307 blood donors collected over six years, ABO phenotype frequency: O (frequency: 38.

Hemolysis and cardiopulmonary bypass: meta-analysis and systematic review of contributing factors.

Background: The use of cardiopulmonary bypass (CPB) is almost inevitable in cardiac surgery. However, it can cause complications, including hemolysis. Until now, there have not been any standards for reducing hemolysis from CPB.

Insights into the diversity of blood donation practice across Asia: How blood collection agencies adapt donor criteria and processes to their population.

Background And Objectives: Securing an adequate blood supply relies on accurate knowledge of blood donors and donation practices. As published evidence on Asian populations is sparse, this study aims to gather up-to-date information on blood donors and donation practices in Asia to assist planning and strategy development.

Materials And Methods: Ten blood collection agencies (BCAs) provided 12 months' data on donors who met eligibility criteria or were deferred, as well as details of their donation practices.

International Society of Blood Transfusion survey of experiences of blood banks and transfusion services during the COVID-19 pandemic.

Background And Objectives: The coronavirus disease 2019 (COVID-19) pandemic has impacted blood systems worldwide. Challenges included maintaining blood supplies and initiating the collection and use of COVID-19 convalescent plasma (CCP). Sharing information on the challenges can help improve blood collection and utilization.

Efficacy and safety of convalescent plasma therapy in patients with moderate-to-severe COVID-19: A non-randomized comparative study with historical control in a referral hospital in Indonesia.

Background: Studies to confirm the efficacy and safety of convalescent plasma (CP) as an adjunctive treatment for COVID-19 are still required especially for the countries where standard treatments are unevenly distributed.

Methods: A non-randomized comparative study was done from June - September 2020 in Dr. Sardjito Hospital, Yogyakarta, Indonesia.

Linn. ethanolic extract inhibits angiogenesis in human lung adenocarcinoma (a549) cells.

Background And Aim: (OS) is a herbal plant, which is easy to find and is widely used as an alternative medication. The previous studies have shown that several species of OS extract have therapeutic properties, and in some cases, antitumor properties. Furthermore, several data have shown the antiproliferative effects of OS extract in cases of breast cancer, human fibrosarcoma, and oral cancer.

Ethanolic extract . induces an apoptosis in human lung adenocarcinoma (A549) cells.

(OS) is tropical herbal plant which is easy to find and widely used as a vegetable food in Indonesia. In last decade, lung adenocarcinoma was in top position as male cancer disease in Indonesia. Recently, emerging data showing the extracts of different species of exhibiting the anti-tumor properties.

Genetic polymorphisms of HLA-DP and isolated anti-HBc are important subsets of occult hepatitis B infection in Indonesian blood donors: a case-control study.

Background: Occult hepatitis B infection (OBI) is defined as the presence of hepatitis B virus (HBV) DNA in the serum and/or liver in HBsAg-negative individuals. OBI is associated with the risk of viral transmission, especially in developing countries, and with progressive liver disease and reactivation in immunosuppressive patients. The objective of this study was to evaluate the relation of OBI to HLA-DP single nucleotide polymorphisms (SNPs) encoding antigen-binding sites for the immune response to HBV infection.

Protective effects of HLA-DPA1/DPB1 variants against Hepatitis B virus infection in an Indonesian population.

Human leukocyte antigen (HLA) DPA1/DPB1 variants have been reported to influence Hepatitis B virus (HBV) infection. HLA-DPA1/DPB1 plays a pivotal role in antigen presentation to CD4(+) helper T cells and influences the outcome of HBV infection. To investigate the influence of HLA-DP variants on the outcome of HBV infection in an Indonesian population where it has the third-highest prevalence of HBV infection worldwide, we performed a case-control study of 686 participants, including patients with HBV-related advanced or nonadvanced liver disease, patients with spontaneously resolved HBV, and healthy controls.

Rare Helicobacter pylori Infection May Explain Low Stomach Cancer Incidence: Ecological Observations in Bali, Indonesia.

The incidence rate of stomach cancer in Bali, Indonesia, is estimated to be strikingly lower than that in Japan. We conducted an on-site ecological study to investigate the association between the stomach cancer incidence and Helicobacter pylori (H. pylori) infection.

Therapeutic apheresis in Asia: An Indonesia single center experience.

In developing countries, like Indonesia, apheresis is still a relative new procedure. Nowadays, therapeutic apheresis procedures are performed in the field of hematology and neurology, especially in the teaching hospitals in Indonesia. Therapeutic apheresis procedure, that is, leukocytapheresis, therapeutic plasma exchange (TPE), and thrombocytapheresis are already performed.
