EMA and EMACO Chemotherapy in High Risk Gestational Trophoblast Disease, which Better? Kemoterapi EMA dan EMACO dalam Risiko Tinggi Penyakit Trofoblas Gestasional, Mana yang Lebih Baik?

Abstract Objective: Determine the best effectiveness and efficacy between EMA and EMACO for patients with high-risk GTN. Results: GTN patients who received EMA showed remissions as high as 74.4% - 96.6% of cases. The side effects of anemia in EMA were less toxic than EMACO, but it wasn’t the case in neutropenia. Two studies showed that 57,1% and 87% patients relapse within 2 years, while none in 5 years and 7 years follow-ups. Discussion: With EMACO use, it has been observed to result in increased morbidity and increased health care costs and when patients experience complications while staying overnight in the hospital, they are not monitored by a good specialist team. Patients treated with EMACO had more peripheral neuropathy as result of vincristine than EMA. The use of EMA certainly requires further evaluation. Conclusion: Patients with High-risk GTN who treated first-line with EMA or EMACO have an excellent prognosis. Both regiments are equally effective. There were differences in treatment scheduling, hospitalization requirements, and toxicity between regimens.   Keywords: EMA, EMACO, gestational trophoblastic neoplasia   Abstrak: Tujuan: Mengetahui efektivitas dan efikasi terbaik diantara EMA dan EMACO untuk pasien dengan NTG berisiko tinggi. Hasil: Pasien dengan NTG yang menerima EMA menunjukkan remisi setinggi 74.4%-96.6% dari kasus. Efek samping anemia dari EMA lebih tidak toksik dibandingkan EMACO, namun tidak dengan neutropenia. Dua studi menunjukkan bahwa 57.1% dan 87% pasien mengalami kekambuhan dalam 2 tahun, namun tidak ada dalam follow up 5 tahun dan 7 tahun. Diskusi: Dengan penggunaan EMACO, dapat diobservasi bahwa terdapat peningkatan morbiditas dan peningkatan biaya pelayanan kesehatan, dan ketika pasien mengalami komplikasi pada saat rawat inap di rumah sakit, mereka tidak dimonitor oleh tim spesialis yang baik. Pasien yang diterapi dengan EMACO memiliki efek samping neuropati perifer lebih tinggi yang disebabkan oleh vinkristin, dibandingkan EMA. Penggunaan EMA membutuhkan evaluasi lebih lanjut. Kesimpulan: Pasien dengan NTG berisiko tinggi yang diterapi dengan lini pertama EMA atau EMACO mempunya prognosis yang baik. Kedua regimen tersebut efektif. Ada perbedaan dalam penjadwalan terapi, kebutuhan rawat inap dan toksisitas antara regimen, Kata kunci: EMA, EMACO, neoplasia trofoblastik gestasional   &nbsp

Pertumbuhan dan Produksi Hijauan Gamal (Gliricidia Sepium) dengan Berbagai Dosis Pupuk Organik Cair

The study was conducted to determine the growth and production gamal using liquid organic fertilizer. The data obtained were analyzed statistically using a completely randomized design (CRD) and tested further if there is a difference between treatments. Treatment of different doses of liquid fertilizer, which is 0%, 1%, 3% and 5% with 5 replicates, 75cmx50cm spacing so that each plot consisted of 16 cuttings of the experiment, the number of 320 eksplant. Implementation of the research carried out for 4 months, with the first 2 months and 2 months uniformity next crop done taking data. Based on the results of this study concluded that liquid organic fertilizer doses on forage gamal low so that growth and high forage production was not achieved. A need to increase doses of more than 5% liquid organic fertilizer
