"ABSTRAKPeningkatan keberhasilan dalam pelayanan kesehatan dan teknologi medis di negaraberkembang termasuk Indonesia yang mengarah ke peningkatan populasi dunia telah diikutioleh peningkatan kebutuhan darah untuk transfusi klinis. Namun, layanan darah di seluruhdunia menghadapi masalah serupa, yaitu kurangnya pasokan darah akibat peningkatanpermintaan, sementara jumlah donor cenderung stabil. Menurut perhitungan WHO, Indonesiamemerlukan darah sekitar 2% dari total populasi yaitu 4,8 juta unit darah per tahun untuk240 juta orang. Partisipasi aktif dan rutin pendonor yang memenuhi syarat sangat diharapkanuntuk memenuhi kualitas yang baik serta darah yang aman. Batasan usia untuk donor darahlansia adalah salah kontributor terjadinya permasalahan kekurangan donor.Sebuah penelitian deskriptif dirancang untuk menguji kelayakan donor darah lansiauntuk memperpanjang sumbangan mereka melampaui batasan usia saat ini. Parameterhematologi yaitu hemoglobin, hematokrit, MCV, MCH, MCHC dan trombosit diukurterhadap dua kelompok pendonor pada UDD DKI, berusia di atas dan di bawah 60 tahun (60-65 tahun dan 17-59 tahun) yang masing-masing terdiri dari 50 subyek penelitian. Dua kalipengukuran hematologi dilakukan pada kedua kelompok saat donor darah pada hari 0 dan 75.Selain itu dilakukan pula pengukuran kontrol dari sampel darah vena pada masing-masingkelompok dilakukan pada hari ke-38Tidak ada perbedaan yang signifikan pada hasil pemeriksaan kedua kelompok.Tingkat pemulihan rata-rata hemoglobin dan paramenters hematologi lainnya untuk keduakelompok donor hampir mendekati bahkan sama dengan level pada hari ke 0 saat donordarah. Sebagai kesimpulan, donor darah lansia terutama pada usia 60 sampai 65 tahun masihpotensial atau memenuhi syarat untuk menjadi donor darah sukarela secara teratur untukmenjaga persediaan darah transfusi yang cukup di Jakarta.Studi lebih lanjut meliputi berbagai lokasi di Indonesia masih diperlukan untukmendapatkan kesimpulan nasional yang lebih akurat

ABSTRACTSuccessful improvement in health services and medical technology in developingcountries including Indonesia leading to the increase in world population has been followedby the increase in the requirement of blood for transfusion clinical practice. However, bloodservices around the world encounter similar problem, namely a lack of blood supply due tothe increase in demands, whilst the number of donors tend to be stable. According to WHOestimation, Indonesia in particular needs approximately 2% of the total population i.e. 4.8million units of blood per year for 240 million people. Active and regular participation ofeligible blood donors are expected to meet the high quality and save blood. Limitation fordonation of elderly blood donors is among contributors for donor shortage.The present descriptive study was designed to examine the eligibility of elderly blooddonors to extend their donation beyond the current age limitation. Hematological parametersi.e. hemoglobin, packed cell volume, MCV, MCH, MCHC and platelet were measured in twogroups of UDD DKI blood donors above and below 60 years of age (60-65 years and 17-59years) consisting of 50 subjects respectively. Twice hematologic measurements were carriedout in both groups during blood donation time on day 0 and 75. In addition once controlmeasurement from venous blood samples of the respective groups was carried out on day 38.No significant different was observed in two groups. Average recovery levels ofhemoglobin and other hematological paramenters for both donor groups almost approachedeven at equal level with level at day 0 of blood donation. In conclusion, elderly blood donorsparticularly in their 60 to 65 years of age were still potential or eligible to be regularvoluntary blood donors to keep sufficient blood donors in Jakarta.Further study encompassing various locations in the country are still required toobtain more accurate nationwide conclusion."

"Tujuan penelitian ini adalah untuk mengetahui apakah terdapat perbedaan antara hasil pemeriksaan hematologi rutin dan morfologi darah tepi eritrosit pada sampel darah dengan berbagai konsentrasi antikoagulan Na2EDTA yang berbeda. Penditian ini merupakan penelitian potong lintang. Bahan penelitian berupa 33 sampel darah vena mahasiswa Fakultas Kedokteran UGM Yogyakarta. Dua ml darah dibagi ke datum 4 tabling Na2EDTA yang masing-masing berisi antikoagulan dengan konsentrasi yang berbeda. Tabung pertama berisi Na2EDTA konsentrasi standar, 2 mg/dl, tabung yang lain secara berurutan berisi Na2EDTA dengan konsentrasi 4 mg/dl, 6 mg/dl, and 8 mg/dl. Sebelumnya dibuat sediaan hapus langsung dari setetes darah tanpa antikoagulan (sebagai kontrol) untuk pemeriksaan morfologi darah tepi (MDT). Darah dalam keempat tabung tersebut segera dilakukan pembuatan sediaan hapus dan diperiksa profit hematologi eritrositnya menggunakan SYSMEX SE-9500 automatic analyzer. Terdapat penurunan yang bermakna dari hitung eritrosit, hemoglobin, hematokrit, dan MCHC serta peningkatan yang bermakna dari nilai MCV dan RDW antara konsentrasi Na2EDTA yang berlebihan, sedangkan nilai MCH tidak ada perbedaan. Pemeriksaan MDT menunjukkan perubahan yang bermakna pada bentuk echinocytes serta ditemukan gambaran ghost cells pada sampel darah dengan Na2EDTA yang berlebihan. Disimpulkan bahwa antikoagulan Na2EDTA yang berlebihan akan berpengaruh terhadap morfologi dan beberapa parameter hematologi eritrosit. (Med J Indones 2006; 15:157-64)

The purpose of this study is to know whether there are differences between hematology profile and morphology of erythrocyles of blood specimens which are prepared with excessive Na2EDTA anticoagulant in different concentration. This study was conducted in Faculty of Medicine Gadjah Mada University. The criteria of subject were male, age from 18 until 22 years old and healthy, ascertained from history taking and vital sign examination. Blood samples from 33 subjects were taken using vein puncture. Two millimeters blood was divided into 4 Na2EDTA-containing tube's. Before that, one drop of blood without Na2EDTA anticoagulant was used for making control blood film right after vein puncture. Each tubes contained different concentration of anticoagulant. The first tube contained Na2EDTA in standard concentration 2 mg/dl; the remaining tubes contained consecutively, 4 mg/dl, 6 mg/dl, and 8 mg/dl. Those samples were immediately examined using SYSMEX SE-9500 automatic analyzer for measuring erythrocytes hematological profile and were stained with Wright staining far morphological examination. These procedures were done before 20 minutes of vein puncture. There were significant decrease ofRBC count, HGB, HCT, and MCHC and also significant increase of MCV and RDW between different concentrations of excessive Na2EDTA anticoagulant. MCH did not have significant result. Morphological examination showed significant morphological changes in the form of echinocytes and appearance of ghost cells in the sample treated with excessive Na2EDTA anticoagulant concentration. In conclusion, there are differences in hematological profile and morphology of erythrocytes among blood specimen which are prepared with excessive Na2EDTA anticoagulant in different concentration, except for MCH. Excessive Na2EDTA anticoagulant concentration will affect the blood specimen for peripheral blood examination of erythrocytes by interfering morphology and some of hematological parameters.

"Perubahan iklim telah menjadi isu global dan diyakini disebabkan oleh aktivitas manusia yang berhubungan dengan produksi gas rumah kaca (greenhouse gases), salah satunya adalah karbon dioksida. Peningkatan konsentrasi karbon dioksida memberikan efek tidak hanya pada lingkungan sekitar, tetapi juga sistem tubuh. Kejadian ini dihubungkan dengan kemunculan berbagai penyakit akibat kondisi hiperkapnia yang menimbulkan efek merusak pada sel dan jaringan tubuh, termasuk sistem imun. PBMC merupakan salah satu komponen penting sistem imun yang berperan sebagai lini pertama tubuh dalam menghadapi berbagai perubahan lingkungan, termasuk peningkatan karbon dioksida. Tingkat karbon dioksida tinggi dapat menimbulkan perubahan pada ekspresi berbagai gen yang berperan dalam meregulasi respon seluler terhadap perubahan yang ada. Salah satu gen yang dimaksud adalah HIF-1α. HIF-1α merupakan salah satu protein faktor transkripsi utama dalam tubuh yang berfungsi untuk mengatur berbagai macam mekanisme seluler terhadap keadaan hipoksia. Oleh karena itu, penelitian ini ditujukan untuk mempelajari lebih lanjut mengenai efek peningkatan karbon dioksida terhadap ekspresi HIF-1α pada PBMC. PBMC dipisahkan teknik sentrifugasi, kemudian dikultur dan disimpan dalam empat keadaan yang berbeda (5% CO2 24 jam, 15% CO2 24 jam, 5% CO2 48 jam, dan 15% CO2 48 jam). Kemudian, RNA diisolasi dan dicek dengan teknik reverse transcriptase real-time PCR. Hasil dari kelompok sampel 24 jam menunjukkan perbedaan yang signifikan dalam hal tingkat ekspresinya. Sedangkan pada kelompok sampel 48 jam, hasil menunjukkan perbedaan ekspresi yang tidak signifikan. Dari penelitian ini, dapat disimpulkan bahwa adanya penurunan ekspresi HIF-1α ketika peningkatan karbon dioksida terjadi. Akan tetapi, ekspresi HIF-1α menunjukkan sedikit peningkatan setelah perlakuan selama 48 jam.

Climate change has become a major global issue since the past few years, and it is caused by human activities related to the emissions of greenhouse gases, one of which is carbon dioxide. Elevated level of carbon dioxide has been found to affect not only our environment, but also our body system. It is linked to many adverse clinical outcomes due to the hypercapnic condition towards many cells and tissues, including our immune system. PBMCs, a major components of immune system, are the first-line defence against various environmental changes, including increased carbon dioxide level. High carbon dioxide are thought to cause alterations of numerous genes expression, including HIF-1α, resulting in defective cellular response. HIF-1α is one of the most important transcription factor proteins for numerous cellular mechanisms related to hypoxia. Therefore, this research is aimed to study about the effects of increased carbon dioxide towards HIF-1α expression in PBMCs. PBMCs are separated from the blood by centrifugation, cultured, and treated under four different conditions (5% CO2 24 hours, 15% CO2 24 hours, 5% CO2 48 hours, and 15% CO2 48 hours. The RNA are then isolated and tested by reverse transcriptase real-time PCR. The result of 24-hour group showed a significant difference in the mRNA expression, unlike the difference in expression showed by the result of 48-hour group. In conclusion, the result showed that the expression of HIF-1α was decreased upon treated with increased carbon dioxide level. The expression, however, slightly increase after 48-hour period."

"ABSTRAKThe scarcity of blood that is still happening today is the result of a combination of high blood needs and the difficulty of recruiting and maintaining donors. There is no research discover the substitute that can replace the role of blood, therefore the only source is from donations or blood donors. Approximately 80% of total blood donations collected by American Red Cross are come from blood drive events. Because blood has 6-hour spoilage time, donated blood at various donation locations must be collected and sent to a blood center for processing in less than 6 hours. This research study the Maximum Blood Collection Routing Problem (MBCRP). This problem is the extension of Vehicle Routing Problem with Time-Window (VRPTW) by considering the spoilage time limitation in blood. A mathematical model with objective to maximize total blood collection is built to cope with this problem. The mathematical model will be tested for verification and validation. The model is written in a computer programming language using AMPL software and is solved using the CPLEX solver. Furthermore, the results of verification and validation tests will be evaluated to see the applicability of the model."

"Latar Belakang: Retinoblastoma adalah keganasan intraokular paling sering dan juga salah satu tumor padat tersering pada anak-anak. Di negara berkembang dimana terdapat perawatan dan deteksi dini yang baik, prognosis umumnya baik dengan tingkat kesintasan tinggi. Sayangnya, di negara berkembang termasuk Indonesia diagnosis umumnya tertunda dan kesintasan masih rendah. Hitung darah lengkap merupakan uji yang secara relative mudah dan murah serta dikatakan dapat memberikan informasi prognostik yang bernilai dan membantu menilai kesintasan pada berbagai jenis kanker. Namun, studi mengenai hal tersebut masih sangat sedikit pada kasus retinoblastoma. Tujuan: Penelitian ini bertujuan untuk mengidentifikasi hubungan antara profil darah tepi pada presentasi awal dan kesintasan pada retinoblastoma. Metode: Penelitian ini menggunakan desain potong lintang retrospektif dengan cara mengumpulkan rekam medis pasien retinoblastoma yang didiagnosis sejak Januari 2011 sampai Desember 2013 di Rumah Sakit Ibu dan Anak Cipto Mangunkusumo 'Kiara'. Demografi dan profil klinis pasien dikumpulkan dan keluaran dikategorikan menjadi event mati dan censored tidak mati . Analisis kesintasan dilakukan menggunakan metode Kaplan Meier dengan SPSS.

Background: Retinoblastoma is the most common intraocular malignancy and is also one of the most common solid tumors in children. In developed countries where treatment is good and early detection is available, the prognosis and survival is good. Unfortunately, in developing countries including Indonesia diagnosis is still often delayed and survival is still low. Complete blood count as a relatively accessible and affordable test has been studied to provide valuable prognostic information and help in assessing the survival in various types of cancers. However, such studies is still very limited in retinoblastoma cases.

Objectives: This study aims to identify the relation between peripheral blood profile on first presentation and survival in retinoblastoma.

Methods: This study uses retrospective cross sectional study design by collecting medical records of retinoblastoma patients diagnosed from January 2011 to December 2013 in Cipto Mangunkusumo Children and Maternal Hospital 'Kiara'. The demography and clinical profile of patients is collected and outcome is categorized into event dead and censored not dead. Survival analysis is done using Kaplan Meier with SPSS.

Results: Survival analysis using Kaplan Meier method and log rank test shows no significant difference in survival between patients, either according to hemoglobin status p 0,219 , leukocyte status p 0,903 , and thrombocyte status p 0,649 before receiving systemic therapy. Nevertheless, there seem to be a trend of lower mean survival in group with abnormal Hb and leukocyte, although such relation is not seen in thrombocyte.Conclusion Although there is no significant relation, there seem to be a trend in which patients with worse peripheral blood profile has worse survival."

"Latar belakang: Transfusi komponen Packed Red Cell (PRC) dengan metode pengurangan sel darah putih (PRC leukodepleted) mulai banyak digunakan untuk terapi pasien karena mampu mengurangi kejadian pasca transfusi yang tidak diinginkan. Jumlah perokok aktif di Indonesia yang cukup tinggi sehingga berpotensi besar menjadi pendonor darah karena belum ada regulasi yang mengaturnya. PRC leukodepleted pada perokok aktif beresiko besar mengalami kerusakan membran sel darah merah dan hemolisis akibat stres oksidatif yang terjadi karena akumulasi radikal bebas pada perokok aktif. Tujuan: Penelitian ini bertujuan untuk mengetahui pengaruh stres oksidatif terhadap ketahanan membran PRC leukodepleted donor perokok aktif selama penyimpanan. Metode: PRC leukodepleted diproduksi dari pendonor yang dikelompokkan menjadi kelompok pendonor non perokok (NP), pendonor perokok ringan (PR) dan pendonor perokok sedang (PS). Sampel penelitian dibagi menjadi 6 aliquot untuk diperiksa kadar malondialdehid (MDA), aktivitas enzim superoksida dismutase (SOD), uji fragilitas osmotik (osmotic fragility test, OFT) dan hemolisis pada hari ke 0, 7, 14, 21, 28 dan 35. Hasil: Berdasarkan uji Kruskal Wallis ketiga kelompok menunjukkan perbedaan bermakna antara H0, H7, H14, H21, H28 dan H35 pada parameter MDA, SOD, OFT dan hemolisis yaitu dengan p<0,05. Dalam larutan NaCl 0,54 % pada uji OFT, terjadi hemolisis kelompok NP sebesar 17,53+12,16% pada H35; kelompok PR sebesar 34,10+7,92% pada H28; dan kelompok PS sebesar 30,92+5,98% pada H0. Kesimpulan: Penyimpanan PRC leukodepleted selama 35 hari meningkatkan stres oksidatif. Stres oksidatif paling tinggi terjadi pada kelompok perokok sedang. Terdapat korelasi antara stres oksidatif dengan ketahanan membran sel darah merah.

Background: Packed Red Cell (PRC) transfusion without the leukocyte (leukodepleted PRC) method has begun to be widely used for patient therapy because it can reduce unexpected post-transfusion effects. The number of active smokers in Indonesia is quite high so they have a great opportunity to become blood donors, since there is no regulation yet. Leukodepleted PRC in active smokers are at great risk for red blood cell membran damage and hemolysis due to oxidative stress that occurs caused by accumulation of free radicals in active smokers. Objective: This study aim to determine the effect of oxidative stress on red blood cells membrane resistance of leukodepleted PRC in active smokers donors during storage. Methods: Leukodepleted PRC was produced from donors who were grouped into non-smoker donors (NP), light smoker donors (PR) and moderate smoking donors (PS). The research sample was divided into 6 aliquots to be examined for the malondialdehyde (MDA) level, activity of superoxide dismutase (SOD) enzyme, osmotic fragility test (OFT) and hemolysis on 0, 7, 14, 21, 28 and 35 days of storage. Results: The three groups showed significant differences between D0, D7, D14, D21, D28 and D35 on the parameters of MDA, SOD, OFT and hemolysis (p<0.05, Kruskal-Wallis test). In 0.54% NaCl solution of OFT test, NP group hemolysis was 17.53+12.16% on D35; PR group was 34.10+7.92% on D28; and the PS group was 30.92+5.98% on D0. Conclusion: Storage for 35 days increased the oxidative stress of leukodepleted PRC. The highest oxidative stress occurred in the moderate smoker (PS) group. Oxidative stress has correlation with red blood cell membrane resistance."
