RESUMEN

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. Body mass index and blood volumes were calculated and analysed. RESULTS: Data on 9,599,613 donations and 154,834 deferrals from six national and four regional BCAs revealed varied donation eligibility and collection practices. Seven used haemoglobin (Hb) criteria below the World Health Organization anaemia threshold. Seven accepted donors weighing <50 kg. Data collection on the weight and height of donors and on deferrals was inconsistent, often not routine. Deferred donors appear to weigh less, with corresponding lower estimated blood volume. CONCLUSION: The diversity in eligibility criteria and donation practices reflects each BCA's strategy for balancing donor health with securing an adequate blood supply. Use of lower Hb criteria substantiate their appropriateness in Asia and indicate the need to define Hb reference intervals relevant to each population. We encourage routine gathering of donor weight and height data to enable blood volume estimation and local optimization of donation volumes. Blood volume estimation formulae specific for the Asian phenotype is needed. Information from this study would be useful for tailoring donation criteria of Asian donors around the world.

RESUMEN

INTRODUCTION: Preeclampsia is a pregnancy complication characterized by high blood pressure and proteinuria. Endothelial dysfunction is a major theory suggested as its aetiology. It is caused by anti-angiogenic condition characterized by low Vascular Endothelial Growth Factor (VEGF). An estradiol metabolite, called 2-Methoxy Estradiol (2-ME), is produced with the help of Catechol-O-Methyltransferase (COMT). This substance has an important role in VEGF expression. A 2-ME is suppressed in women with preeclampsia. AIM: To compare 2-ME in women with severe preeclampsia and normotensive pregnancy. MATERIALS AND METHODS: A total of 80 subjects qualified the inclusion and exclusion criteria, were divided into two groups (40 each): the severe preeclampsia and the normotensive pregnancy. Blood sample was collected and examined with the ELISA 2-ME kit (Cayman). The data were compared and calculated using Fisher-Exact test to examine 2-ME differences between the two groups. RESULTS: Women age, parity, and gestational age showed a non significant difference between both groups. Nonetheless, the BMI before pregnancy and the history of preeclampsia in the past pregnancy showed significant differences. In this study, the 2-ME value was lower in the severe preeclampsia group compared to the normotensive. CONCLUSION: This study concludes that 2-ME value in severe preeclampsia is lower than normotensive pregnancy. A lower 2-ME value may indicate COMT not producing enough 2-ME which in turn may cause the pre-eclampsia.

RESUMEN

BACKGROUND: Anaemia is a common health problem among pregnant women and a contributing factor with a major influence on maternal mortality in Indonesia. The Four Pillars Approach is a new approach to anaemia in pregnancy, combining four strategies to improve antenatal and delivery care. The primary objective of this study is to measure the effectiveness of the Four Pillars Approach. The barriers, the facilitators, and the patients' as well as the midwives' satisfaction with the Four Pillars Approach will also be measured. METHODS/DESIGN: This study will use a cluster randomised controlled trial. This intervention study will be conducted in the Public Health Centres with basic emergency obstetric care in Yogyakarta Special Province and in Central Java Province. We will involve all the Public Health Centres (24) with emergency obstetric care in Yogyakarta Special Province. Another 24 Public Health Centres with emergency obstetric care in Central Java Province which have similarities in their demographic, population characteristics, and facilities will also be involved. Each Public Health Centre will be asked to choose two or three nurse-midwives to participate in this study. For the intervention group, the Public Health Centres in Yogyakarta Special Province, training on the Four Pillars Approach will be held prior to the model's implementation. Consecutively, we will recruit 360 pregnant women with anaemia to take part in part in the study to measure the effectiveness of the intervention. The outcome measurements are the differences in haemoglobin levels between the intervention and control groups in the third trimester of pregnancy, the frequency of antenatal care attendance, and the presence of a nurse-midwife during labour. Qualitative data will be used to investigate the barriers and facilitating factors, as to nurse-midwives' satisfaction with the implementation of the Four Pillars Approach. DISCUSSION: If the Four Pillars Approach is effective in improving the outcome for pregnant women with anaemia, this approach could be implemented nationwide and be taken into consideration to improve the outcome for other conditions in pregnancy, after further research. TRIAL REGISTRATION: Current Controlled Trials ISRCTN35822126.

RESUMEN

BACKGROUND: This study was conducted to examine access to contraception and change in contraceptive methods before and after the disaster in Bantul area, and to evaluate the prevalence of unplanned pregnancy. STUDY DESIGN: In total, 450 married women participated. Questionnaires, which included participants' background, contraceptive methods, difficulties in accessing contraceptive method, and unplanned pregnancy, were completed. RESULTS: Within 1 year of the disaster, the percentage of participants who used injections and implants tended to decrease, while the percentage of participants who used pills tended to increase. Use of coitus interruptus significantly increased after the disaster. The prevalence of unplanned pregnancy was significantly higher in a group of participants who had difficulty accessing contraceptive methods compared to a group that did not. CONCLUSIONS: Health personnel should not only actively deliver contraceptive methods in a disaster situation but also educate couples to prevent unplanned pregnancy.
