    • Authors: Ketut Aryastami; Harimat Hendarwan, Vivi Setiawaty, Amir Su'udi, Ully Adhie Mulyani, Made Dewi Susilawati, Syachroni Syachroni, Nelly Puspandari, Agus Suwandono
      Abstract: Latar belakang: Penyakit jenis baru COVID-19 yang disebabkan oleh virus corona menjadi  sebuah pandemic di akhir tahun 2019. Kota Wuhan (China) merupakan lokasi pertama terdeteksinya kasus COVID-19. Tanpa adanya kecurigaan apapun penyakit ini dengan cepatnya menyebar ke seluruh dunia mengikuti alur mobilitas manusia. Dalam kondisi tersebut sistem kesehatan di setiap negara tampak kelabakan khususnya dalam pengendalian transmisi penyakit. Studi ini ingin mengidentifikasi  kesiapan jejaring laboratorium kesehatan di Indonesia. Metode: Penilaian cepat dilakukan terhadap ketersediaan dan kesiapan laboratoriaum dalam pennanganan pandemi Covid-19. Pengumpulan data dilakukan melalui pengisian questioner yang dikirim secara elektronik. Waktu pelaksanaan adalah minggu ketiga dan keempat, Maret 2020. Terdapat 44 laboratorium jejaring laboratorium dibawah Kementerian Kesehatan yang menjadi subjek penelitian, dan sebanyak 33 yang merespon secara lengkap Variabel ketersediaan, kecukupan dan kebutuhan bahan dan alat. Hasil: Jejaring laboratorium kesehatan dibawah Kementerian Kesehatan sudah terbentuk sejak tahun 2009. Dengan terjadinya pandemic COVID-19 Surat Keputusan Menteri Kesehatan telah direvisi hingga dua kali agar dapat  meningkatkan kapasitas dan memperluas jejaring ke seluruh wilayah NKRI. Hasil studi menunjukkan, laboratorium  jejaring  dibawah Kementerian Kesehatan belum siap dalam menghadapi pandemic COVID-19. Dua jenis laboratorium jejaring yaitu laboratorium surveillans maupun laboratorium diagnostic memiliki kondisi yang sama. Ketersediaan bahan dan alat laboratorium standar masih tergolong rata-rata, bahkan dari sisi kecukupannyapun masih  jauh dibawah kapasitas kebutuhan dalam penanganan specimen COVID-19. Kondisi yang sama juga tampak untuk bahan pendukung laboratorium termasuk alat pelindung diri untuk petugas. Kesimpulan: Kesiapan laboratorium sebagai bagian dari system kesehatan dalam kondisi pandemic masih lemah. Keberadaan alat penunjang diagnose khususnya untuk penyakit menular harus dilengkapi sesuai dengann type laboratorium. Pandemi COVID-19 menjadi alarm dalam menghadapi era baru dan antisipasi masalah dimasa yang akan datang. Kata kunci: Kesiapan laboratorium, COVID-19, Indonesia   Background: A novel coronavirus disease called COVID-19 has become pandemic in late 2019. Wuhan City was the first place detected as the source of the pandemic. Without suspicion, it spreads over the world, along with human mobility. In such a condition, every country seems quite stuttering to prepare its health system to prevent its people from the possible transmission. This paper aims to describe the preparedness of the networking laboratory in Indonesia. Methods: We conducted a rapid assessment of laboratory availability and preparedness to respond to the Covid-19 pandemic. We held the data collection on the third and fourth week of March 2020 by sending an electronic questionnaire to all 44 networking laboratories under the Ministry of Health structure. The variables assessed in this study were the availability and the requirements of the Covid-19 related laboratory's substances, including reagents and other equipment types. Results: The Ministry of Health established the networking laboratory in 2009, but due to the COVID-19 pandemic, it has renewed twice to enhance and expand the laboratory capacities over the country. Our studies showed preparedness among networking laboratories in Indonesia regarding this new emerging COVID-19 condition was quite devastating. Both surveillance and diagnostic laboratories have a similar situation. The availability of their primary materials was mediocre, but the adequacy was far beyond the capacity in handling the COVID-19 specimen. We found a similar case in the laboratory, supporting materials, and personal protective equipment (PPE). Conclusion: Laboratory preparedness during initial period of time of the COVID-19 pandemic as part of the health system is still weak. The availability of the necessary equipment, supporting materials, and personal protective equipment are far beyond the requirements. The COVID-19 has alarmed the laboratory and the whole health system in Indonesia into a new era with better future preparedness. Keywords: laboratory preparedness, COVID-19, Indonesia

    • Authors: Kristivani Br Ginting; Muhammad Rizki Yaznil, M. Oky Prabudi, Lili Rahmawati
      Abstract: Latar belakang: Kanker ovarium memiliki angka mortalitas yang cukup tinggi dikarenakan gejalanya yang tidak spesifik, sering ditemukan pada stadium lanjut, dan belum adanya metode deteksi dini yang sudah terbukti. Untuk menilai keberhasilan terapi penyintas kanker ovarium, tidak hanya dinilai dari aspek klinis tetapi juga dinilai dari kualitas hidup penyintas kanker ovarium yang penilaiannya berdasarkan skala fungsional dan skala gejala dalam kuesioner EORTC QLQ C30 dan EORTC QLQ OV28. Metode: Penelitian ini menggunakan desain penelitian cross sectional, menggunakan data primer dari hasil wawancara dengan kuesioner EORTC QLQ C30 dan EORTC QLQ OV28 serta data sekunder yang berasal dari rekam medik di RSUP Haji Adam Malik Medan tahun 2017 - 2018. Sampel penelitian dipilih dengan metode total sampling dari seluruh data rekam medik yang memenuhi kriteria penelitian.   Hasil: Hasil penelitian ini didapatkan kualitas hidup global penyintas kanker ovarium 89.36% adalah baik, dan 10.64% adalah sedang serta tidak ada yang memiliki kualitas hidup buruk. Namun, didapatkan adanya gangguan pada skala fungsional berupa: fungsi emosional, fungsi kognitif, fungsi seksual, dan sikap terhadap penyakit, serta adanya permasalahan pada skala gejala berupa: kelelahan, nyeri, neuropati perifer, dan gejala menopause. Didapatkan juga tidak ada hubungan karakteristik usia, jenis histopatologis, stadium, lama terapi dengan kualitas hidup penyintas kanker ovarium, namun terdapat hubungan antara jenis terapi dengan kualitas hidup penyintas kanker ovarium. Kesimpulan: Kualitas hidup penyintas kanker ovarium secara global adalah baik. Kata Kunci: Kualitas Hidup, Penyintas Kanker Ovarium, EORTC QLQ C-30, EORTC QLQ     OV-28   Background: Ovarian cancer has a high mortality rate due to nonspecific symptoms, often found at an advanced stage, and also the absence of proven early detection methods. To assess the success of ovarian cancer survivors therapy, it is not only assessed from the clinical aspect but also from the quality of life of ovarian cancer survivors which is based on the functional and symptom scale in the EORTC QLQ C30 and EORTC QLQ OV28 questionnaires.  Methods: This study used a cross-sectional study design, using primary data from interviews with the survivors based on the questionnaire EORTC QLQ C30 and EORTC QLQ OV28 as well as secondary data derived from medical records at Haji Adam Malik General Hospital Medan in 2017 - 2018. The research sample was used with a total sampling method from all medical record data that fulfill the research criteria.  Result: The quality of life of ovarian cancer survivors is generally good (89.36%), meanwhile the rest is moderate (10.64%) without the poor quality of life. However, there are disorders on the functional scale in the form of emotional function, cognitive function, sexual function, and attitude toward disease. Likewise on the scale of symptoms, there are problems including: fatigue, pain, peripheral neuropathy, and menopausal symptoms.  Conclusion: The quality of life of ovarian cancer survivors globally is good.

      Abstract: Latar belakang : Hipoalbuminemia pada pasien rawat inap berkaitan dengan prognosis buruk pasien. Penelitian ini, mengidentifikasi bahwa hipoalbuminemia berat pada awal pasien masuk rawat inap sebagai prediktor andalan penanda laboratorium dalam mortalitas. Metode : Sebuah studi cross sectional pada pasien dewasa dengan hipoalbuminemia (kadar albumin < 3,5 g / dL) pada pasien rawat inap (usia > 18 tahun) pada periode Januari 2013 - Maret 2018. Kami mengevaluasi penanda prediktor kematian. Multivariat dengan regresi logistik diterapkan dalam penelitian ini. Hasil : Dari 747 hipoalbuminemia pada pasien rawat inap dengan rata-rata kadar albumin  pada awal adalah 2,0 ± 0,6 g / dL. Sebagian besar pasien (83,4%) memiliki kadar albumin ≤ 2,5 g / dL (hipoalbuminemia berat), 16,6 persen memiliki > 2,5 g / dL (hipoalbuminemia ringan-sedang). Kondisi yang mendasari pasien adalah infeksi HIV / AIDS (26,9%) dan sepsis (26,6%). Proporsi multiple komorbiditas pada kelompok hipoalbuminemia berat adalah 55,1 persen Pada kelompok hipoalbuminemia berat terutama untuk kadar albumin 2,01 - 2,5 g / dL, angka mortalitas adalah 28,3 persen. Berdasarkan model regresi logistik akhir, faktor risiko kematian meliputi kadar albumin pada awal dan lama rawat pasien. Mortalitas lebih tinggi pada pasien dengan hipoalbuminemia berat (rasio odds yang disesuaikan 2,91, 95% CI 1,88-4,50) dibandingkan pasien dengan hipoalbuminemia ringan-sedang. Kesimpulan: Hipoalbuminemia berat pada awal pasien rawat inap sebagai prediktor penanda kematian di rumah sakit.  Kata kunci: hipoalbuminemia, pasien rawat inap, mortalitas   Background: Hypoalbuminemia in hospitalized patients has been associated with poor prognosis. In this study, we attempted to identify that severe hypoalbuminemia at baseline in hospitalized patients is a reliable predictor of laboratory marker for mortality.
      Methods: A cross sectional study on adults of hypoalbuminemia (albumin level < 3.5 g/dL) in hospitalized patients (aged > 18 years old) in period January 2013 - March 2018. We evaluated the predictor marker of mortality. Multivariate with the logistic regression was applied in this study.
      Results: Of the 747 hypoalbuminemia in hospitalized patients with the mean albumin level at baseline was 2.0 ± 0.6 g/dL. Most patients (83.4 %) had less than or equal to 2.5 g/dL albumin level (severe hypoalbuminemia), 16.6 percent had over 2.5 g/dL (mild-moderate hypoalbuminemia). The underlying condition of patients was HIV/AIDS infection (26.9%) and sepsis (26.6 %). The proportion of multiple comorbidities in the severe hypoalbuminemia group was 55.1percent. In the severe hypoalbuminemia group especially for 2.01 – 2.5 g/dL albumin level, the mortality rate was 28.3 percent. Based on the final logistic regression model, known risk factors of mortality include albumin level at baseline and length of stay. Mortality was higher among patients with severe hypoalbuminemia (adjusted odds ratio 2.91, 95 % CI 1.88-4.50) than patients with mild-moderate hypoalbuminemia.
      Conclusion: Severe hypoalbuminemia at baseline in the hospitalized patients was a predictor laboratory
      marker of hospital mortality.

Metode: Penelitian potong lintang pada satu rumah sakit pemerintah di Jakarta. Sampel menggunakan semua data klaim pasien BPJS selama periode Januari - Desember 2017. Semua pasien BPJS  berusia di bawah 18 tahun yang dirawat dimasukkan dalam analisis. Regresi logistik digunakan untuk menganalisis faktor risiko kematian anak. Hasil: Dari total 18,941 jumlah pasien BPJS yang dirawat, sebanyak 3689 data anak yang dianalisis. Proporsi angka kematian anak selama satu tahun sebesar 7,3%. Kasus dengan tingkat keparahan derajat II memiliki risiko kematian 11,51 kali lipat [rasio odds suaian (ORa) = 11,51; IK=7,45-17,78; P = 0,000] dibandingkan tingkat keparahan penyakit derajat I, sedangkan kasus dengan tingkat keparahan derajat III beresiko terhadap kematian 33,97 kali lipat (ORa = 33,97;IK=19,93-57,91; P = 0,000). Selain itu, anak yang memiliki indikasi dirawat di ICU meningkatkan risiko kematian  14,21 kali lipat (ORa = 14,21; IK=9,15-22,08; P= 0,000) dibandingkan yang tidak ada indikasi ICU. Kondisi tertentu yang timbul pada  periode perinatal meningkatkan risiko kematian anak 7,65  kali lipat (ORa = 7,65  ; IK=1,81-32,35;P = 0,006) dibandingkan penyakit pada sistem muskuloskeletal dan jaringan ikat. Kesimpulan: Tingkat keparahan penyakit, indikasi ICU dan kondisi tertentu yang timbul pada  periode perinatal adalah faktor risiko kematian anak yang paling sering di rumah sakit Kata kunci: Faktor risiko, kematian, anak, BPJS   Background: Hospital death rate is one of the indicators used to measure hospital performance and quality of care, especially the overall hospital death rate. This study aims to analyze the risk factors of death among children hospitalized with social insurance (BPJS) in one hospital in Jakarta. Methods: This was a cross-sectional study conducted in one government hospital in Jakarta. The sample was all individual claim data of BPJS patients who were hospitalized during the period of January to December 2017. All BPJS patients aged below 18 years admitted into the pediatric wards were included in the analysis. The logistic regression was used to analyze the risks of children death Results: A total of 18.941 BPJS inpatients in the hospital was identified, out of them 3689 met the inclusion criteria. The proportion of death in children during one year was 7.3%. Illness severity level II had 11.51-fold [adjusted odds ratio (ORa)=11.51;CI=7.45-17.78; P=0.000]] meanwhile severity level III had 33.97-fold higher risk of children death (ORa=33.97; CI=19.93-57.91;P=0.000) compared to children with severity level I. Children who had ICU indicator increase risk of children death at 14.21 -fold (ORa=14.21;IK=9.15-22.08;P= 0.000) compared to those who did not have. Furthermore the risk of children death in certain conditions originating in the perinatal period increases by 7.65–fold (ORa=7.65 ;IK=1.81-32.35;P=0.006) compared to diseases of the musculoskeletal system and connective tissue.

  • In silico analysis of antihypertensive and hepatotoxicity potential of the
           n-butanol fraction of the methanol extract of of cantaloupe (Cucumis melo
           var. cantalupensis)

    • Authors: Dian Laila; Dianita Rifqia Putri, Galuh Wening Permatasari
      Abstract: Latar belakang: Hipertensi merupakan faktor risiko utama penyakit kardiovaskular. Penduduk Indonesia cenderung mengkonsumsi herbal dalam terapi hipertensi dalam mempertahankan kadar tekanan darah seperti buah blewah (Cucumis melo var. cantalupensis). Namun mekanisme kerja buah blewah dalam menurunkan tekanan darah, dan potensi toksisitasnya jika dikonsumsi dalam jangka panjang masih belum jelas. Tujuan studi ini adalah untuk menganalisis mekanisme antihipertensi dari buah blewah dan potensi toksiknya melalui pendekatan in silico. Metode: Bubuk blewah kering dimaserasi menggunakan metanol absolut, difraksinasi menggunakan n-butanol. Uji fitokimia dilakukan dengan metode LC-MS, kemudian senyawa bioaktif ditelusuri hingga SMILESnya di PubChem. Analisis QSAR untuk analisis potensi antihipertensi dilakukan dengan PASS server. Kelas toksisitas dan potensi hepatotoksisitas dianalisis menggunakan ProTox-II, dilanjutkan dengan analisis networking menggunakan STITCH dan STRINGdb. Hasil: Setidaknya terdapat 434 jenis senyawa yang terdapat pada fraksi n-butanol dari ekstrak metanol buah blewah (FBEMB). Berdasarkan analisis STITCH dan STRINGdb, FBEMB dapat bekerja dalam menurunkan tekanan darah melalui mekanisme aksi seperti senyawa amlodipine, yang menstabilkan saluran kalsium tipe-L yang terisi tegangan dalam konformasi tidak aktifnya. Dengan demikian, mencegah kontraksi myocyte yang bergantung pada kalsium dan vasokonstriksi. FBEMB mungkin berpotensi hepatotoksik melalui mekanisme kerja senyawa seperti itrakonazol yang menghambat enzim sitokrom P450 yang mempengaruhi gangguan pada sintesis ergosterol, dan efavirenz yang memiliki efek neurotoksik. Penghambatan sitokrom P450 dapat menyebabkan toksisitas obat dan kerusakan hati. Kesimpulan: FBEMB dapat bekerja dalam menurunkan tekanan darah melalui mekanisme penstabilan saluran kalsium tipe-L yang terisi tegangan dalam konformasi tidak aktifnya. Kata kunci: in silico, antihipertensi, hepatotoksisitas, blewah   Background: Hypertension is a major cardiovascular disease risk factor. Indonesian people tend to consume herbal medicine to maintain hypertension therapy, i.e cantaloupe (Cucumis melo var. cantalupensis). However, the mechanism of action of cantaloupe in lowering blood pressure and toxicity potential for long term consumption is unclear. The study aimed to analyze the antihypertensive mechanism of cantaloupe and its toxic potential through the in silico. Methods: The dried cantaloupe powder was macerated using absolute methanol, then fractionated using n-butanol. The phytochemical test was done by LC-MS method, then the bioactive compounds were traced to their SMILES in the PubChem. The QSAR analysis of the antihypertensive potential was done using the PASS server. The toxicity class and hepatotoxicity potential were analyzed using ProTox-II, followed by networking analysis using STITCH and STRINGdb. Results: At least 434 types of compounds were shown in the n-butanol fraction of the methanol extract of cantaloupe (BFMEC). Based on the networking analysis, BFMEC may work in lowering blood pressure through the action mechanism of the amlodipine compound-like, which stabilizes voltage-gated L-type calcium channels in an inactive conformation, thus, prevents calcium-dependent myocyte contraction and vasoconstriction. BFMEC presumably has hepatotoxic through the action mechanism of itraconazole compound-like inhibited cytochrome P450-dependent enzymes, affecting the impairment of ergosterol synthesis, and efavirenz which has neurotoxic effects. The inhibition of cytochrome P450 may cause drug toxicity and liver damage. Conclusion: BFMEC may work in lowering blood pressure through the action mechanism which stabilizes voltage-gated L-type calcium channels in an inactive conformation.

  • In silico analysis of V48A dihydropteroate synthase mutation to dapsone on
           Mycobacterium leprae from Papua

    • Authors: Yustinus Maladan; Hana Krismawati, Hotma Martogi Laurensia Hutapea, Antonius Oktavian
      Abstract: Latar belakang: Lepra merupakan penyakit yang disebabkan oleh Mycobacterium leprae. Resistensi obat merupakan salah satu tantangan dalam pemberantasan kusta khususnya di Papua. Adanya mutasi pada gen folP1 penyandi dihydropteroate synthase (DHPS) merupakan dasar untuk deteksi molekuler resistensi dapson pada penyakit lepra. Tujuan penelitian ini adalah mendeteksi mutasi pada gen folP1 Mycobacterium leprae dari Papua, Indonesia dan menganalisis pengaruh mutasi tersebut terhadap dapson dengan metode in silico.
      Metode: Identifikasi mutasi pada gen folp1 M. leprae dilakukan melalui proses Basic Local Alignment Search Tool (BLAST) di gene bank. Analisis efek mutasi dengan menggunakan server Have (y) Our Protein Explained (HOPE). Prediksi binding pocket menggunakan Computed Atlas of Surface Topography of proteins (CASTp). Homologi modeling struktur 3D DHPS menggunakan server Iterative Threading ASSEmbly Refinement (I TASSER). Analisis docking dengan menggunakan AutoDock Vina yang terintegrasi dengan aplikasi Python Prescription (PyRx).
      Hasil: Hasil sekuensing menunjukkan adanya variasi dalam gen folP1 M. leprae yaitu perubahan dari Timin (T) menjadi Sitosin (C) pada nukleotida 143. Residu yang bermutasi (V48A) terletak pada domain yang penting untuk aktivitas protein dan kontak dengan residu di domain lain. Ada kemungkinan bahwa interaksi ini penting untuk fungsi protein secara benar. Mutan V48A tidak banyak mempengaruhi stabilitas dari dihydropteroate synthase M. leprae.
      Kesimpulan: Berdasarkan analisis molecular docking, mutasi V48A tidak mempengaruhi binding affinity dapson terhadap dihydropteroate synthase M. leprae. Hasil ini menunjukkan mutan V48A kemungkinan tetap
      rentan terhadap dapson. Dengan demikian perlu dilakukan uji in vivo untuk mengkofirmasi efek mutasi V48A. Kata kunci: Mycobacterium leprae, folP1 gene, dihydropteroate synthase, dapson  

      Background: Leprosy is a disease caused by Mycobacterium leprae. Drug resistance is one of the challenges in leprosy elimination especially in Papua. The presence of mutations in folP1 gene that encode dihydropteroate synthase (DHPS) was considered as the exclusive basis for molecular detection of dapsone resistance in leprosy. The objective of this study was to detect mutations in the folP1 gene of Mycobacterium leprae from Papua, Indonesia and to analyze the effect of these mutations on dapsone using the in-silico method.
      Methods: Identification of mutations in the folp1 M. leprae gene is carried out through the Basic Local Alignment Search Tool (BLAST) process in the gene bank. The analysis of the effects of mutations using the Have (y)Our Protein Explained (HOPE) server. Bindings pocket prediction is done using the Computed Atlas of Surface Topography of proteins (CASTp). Homology modeling 3D structure of DHPS using the Iterative Threading ASSEmbly Refinement (I-TASSER) server. Docking analysis was performed using AutoDock Vina which is integrated with the Python Prescription (PyRx) application.
      Results: The sequencing results showed a variation in the folP1 M. leprae gene, namely a change from thymine (T) to cytosine (C) in nucleotide 143. The mutated residue (V48A) is in a domain that is essential for the activity of the protein and in contact with residues in another domain. It is possible that this interaction is important for the correct function of the protein. V48A mutants did not significantly affect the stability of DHPS M. leprae.
      Conclusion: Based on molecular docking analysis, this mutation does not affect binding affinity dapsone against M. leprae dihydropteroate synthase. These results indicate that the V48A mutant is likely to remain susceptible to dapsone. Thus, it is necessary to do an in vivo test to confirm the effect of the V48A mutation.

           pathogenic Leptospira in the urine samples

    • Authors: Farida Dwi Handayani; Rahmi Ayu Wijayaningsih, Muhammad Hussein Gasem, Tri Wibawa
      Abstract: Latar belakang: Leptospirosis merupakan zoonosis penting di dunia, yang masih sering terjadi salah diagnosis. Deteksi laboratorium Leptospira menjadi tantangan karena bakterimea cukup singkat untuk dideteksi molekuler, namun antibodi juga muncul sangat lambat. Urine dapat menjadi sampel alternatif untuk deteksi PCR pada leptospirosis. Pengerjaan PCR membutuhkan DNA berkualitas dan andal, dan diperoleh dari metode ekstraksi DNA yang baik. Penelitian bertujuan untuk mengetahui metode ekstraksi DNA Leptospira terbaik untuk sampel urin, serta mengevaluasi pengaruh waktu penyimpanan dan suhu terhadap kestabilan DNA.
      Metode: Penelitian ini menggunakan tiga metode isolasi DNA yang berbeda; berbasis silika dengan spin kolom, kromatografi spin column menggunakan resin sebagai matriks pemisah, dan metode larutan dengan guanidine isothiocyanate. Hasil ekstraksi diperiksa konsentrasi dan kemurniannya. Gen SecY pada Leptospira dideteksi dengan PCR real-time. Pengaruh suhu dan lama penyimpanan DNA juga dilihat.
      Hasil: Hasil isolasi DNA menggunakan resin menunjukkan konsentrasi tertinggi (7,94 + 2,11 μg / mL) dan jumlah salinan amplifikasi DNA Leptospira tertinggi (50167,92 + 1,19). Suhu penyimpanan pada suhu 4°C, -20°C, dan -80°C dan umur simpan 91 hari tidak berpengaruh terhadap kualitas dan kuantitas DNA Leptospira hasil isolasi spike urin.
      Kesimpulan: Isolasi DNA menggunakan spin column chromatography dengan resin sebagai matriks separasi memiliki kualitas dan kuantitas terbaik berdasarkan kemurnian dan konsentrasi DNA serta jumlah gen SecY yang teramplifikasi. Kata kunci: Leptospira, Leptospirosis, ekstraksi DNA, sampel urin, penyimpanan sampel.  
      Background: Leptospirosis is a worldwide zoonotic disease, which is still often misdiagnosed. Laboratory detection of Leptospira is challenging since the bacteraemia is quite short for molecular detection, however, the rise of the antibody is late to post the infection. Urine can be a potential alternative sample for PCR detection in leptospirosis. The PCR method requires a reliable DNA template, which is obtained from good DNA extracting methods. The study aimed to determine the best method of extraction Leptospira DNA from the urine sample, as well as evaluating the effect of time storage and temperature for its DNA stability.
      Methods: This study was utilizing three different DNA isolation methods; silica based with spin column, spin column chromatography using resin as separation matrix, and solution method with guanidine isothiocyanate. The yields were examined for its concentration and purity. Leptospira’s SecY gene was detected with realtime PCR. The influences of storage temperature and the life time of the DNA were also studied.
      Results: The yield of DNA isolation using resin showed the highest concentration (7.94+2.11 μg/mL) and highest Leptospira DNA amplification copy number (50167.92+1.19). Storage temperature at 4°C, -20°C, and -80°C and life time of 91 days did not have any effect on the quality and quatnity of Leptospira DNA isolated from spiked urine.
      Conclusions: DNA isolation using spin column chromatography with resin as separation matrix has the best quality and quantity based on the purity and concentration of DNA and the higher number of amplified SecY gene.

    • Authors: Rachma Greta Putri; Sari Eka Pratiwi, Didik Setyo Heriyanto, Danarto Danarto, Indwiani Astuti, Nur Arfian, Sofia Mubarika Haryana
      Abstract: Latar Belakang: Gangguan regulasi mikroRNA(miR) dan inflamasi kronik dapat mengubah tumor menjadi karsinoma dan kanker dengan metastasis melalui perubahan seluler dan genomik. Lesi prekanker memiliki peluang 33,3 persen menjadi kanker. Penelitian ini bertujuan untuk mengkaji peran miR-155-5p terhadap mRNA SOCS1 dan populasi makrofag terhadap progresivitas penyakit yang berhubungan dengan Benign Prostate Hyperplasia (BPH), High Grade Prostatic Intraepithelial Neoplasia (HGPIN), dan Prostate Adenocarcinoma (PRAD). Metode: Penelitian ini merupakan penelitian potong lintang dengan 3 kelompok, yaitu BPH,HGPIN, dan PRAD. Sampel jaringan didapatkan dari Tindakan TURP. Ekspresi miR-155 dianalisis menggunakan qPCR dan dikalkulasi menggunakan metode Livak. Ekspresi mRNA SOCS-1 dianalisis menggunakan reverse transcriptase PCR. Penanda pan makrofag, anti CD-68 monoclonal antibody(MoAb) digunakan untuk mendeteksi populasi makrofag pada jaringan dengan imunohistokimia. Hasil: Ekspresi miR-155 lebih tinggi pada HGPIN dibandingkan BPH dan PRAD (p=0,14). Ekspresi mRNA SOCS1 pada HGPIN paling rendah diantara ketiga sampel (p=0,96). Terdapat korelasi negative antara miR-155 dan mRNA SOCS1 (p=0,02). Terdapat peningkatan persentase populasi makrofag yang signifikan pada HGPIN (6,03 persen) dibandingkan BPH (0.89 persen) dengan p=0,00. Kesimpulan: Pada penelitian ini, terdapat perubahan persentase makrofag dan miR-155 pada HGPIN. Variasi ekspresi miR-155 dan persentase populasi makrofag dapat disebabkan karena perubahan epigenetik. Oleh sebab itu, perlu penelitian lebih lanjut untuk memvalidasi hasil tersebut dan memahami  kemungkinan menjadi biomarker pada penyakit prekanker pada prostat. Kata Kunci: Prostatic Intaepithelial Neoplasia, miR-155, Makrofag     Background: Impaired microRNA(miR) regulation and chronic inflammation could transform tumors into carcinoma and cancer by metastasis through cellular and genomic changes. Precancerous lesions have a 33.3 percent chance of becoming cancerous. This study investigated the role of miR-155 related to SOCS1 mRNA and macrophage population in disease progression associated  with Benign Prostate Hyperplasia (BPH), High-Grade Prostatic Intraepithelial Neoplasia (HGPIN), and Prostate Adenocarcinoma (PRAD). Methods: This was a cross-sectional study using three groups of samples, namely BPH, HGPIN, and PRAD. Tissue samples were obtained from TURP Action. The expression of miR-155 was analyzed using real-time qPCR and calculated using the Livak method. The expression of SOCS1 mRNA was analyzed using reverse transcriptase PCR. The macrophage pan-marker, anti-CD68 monoclonal antibody (MoAb), was used to detect macrophage population in tissues by immunohistochemistry. Results: The expression of miR-155 was higher in HGPIN than BPH and PRAD (p=0.14). The expression of SOCS1 mRNA in HGPIN was the lowest among the three samples (p=0.96). There was a negative correlation between miR-155 and SOCS1 mRNA (p=0.02). There was a significant increase in the percentage of the macrophage population in HGPIN (6.03 percent) compared to BPH (0.89 percent) with p=0.00. Conclusion: In this study, there were changes in the percentage of macrophage and miR-155 in HGPIN. The variation in miR-155 expression and the percentage of the macrophage may be caused by epigenetic changes. Therefore, further research is needed to validate these results and understand the possibility of being a biomarker in precancerous disease of the prostate.

    • Authors: Sri Nuryani Wahyuningrum; Christina Prihharsanti, Sofia Mubarika Haryana, Ahmad Ghozali, Firly Putri Fardhila
      Abstract: Latar belakang: Angka kekambuhan dan resistensi pasien kanker rektum mencapai 40 persen. Kondisi tersebut bisa disebabkan karena peningkatan ekspresi GLUT-1 dan VEGF-A, serta mempengaruhi prognosis pasien. Tujuan penelitian ini adalah untuk mengetahui korelasi ekspresi mRNA GLUT-1 dan VEGF-A, serta hubungannya dengan prognosis pasien kanker rektum yang menjalani kemoradiasi.
      Metode: Penelitian Kohor ini melibatkan 16 orang pasien kanker rektum lokal stadium II atau III yang menjalani kemoradiasi di RSUP Kariadi Semarang. Sampel darah intravena diambil 5 mL pada saat sebelum dan sesudah kemoradiasi. Total RNA diisolasi dari 200 μl serum, kemudian dilakukan sintesis cDNA. Ekspresi mRNA GLUT-1 dan VEGF-A dikuantifikasi dengan metode Livak menggunakan reference gene β-actin.
      Hasil: Rata-rata ekspresi mRNA GLUT-1 menurun signifikan 2,14 kali (P=0,044) dan mRNA VEGF-A menurun 1,9 kali (P = 0,03). Ekspresi mRNA GLUT-1 dan VEGF-A berkorelasi positif kuat dan signifikan pada saat sebelum (r = 0,6; R2 = 0,455; P = 0,013) dan sesudah kemoradiasi (r = 0,8; R2 = 0,598; P < 0,001). Peningkatan ekspresi mRNA GLUT-1 berhubungan dengan prognosis buruk pasien, dengan resiko 18 kali lebih tinggi (P=0,036; OR=18, 95% CI=1,2 – 261). Peningkatan ekspresi mRNA VEGF-A tidak berhubungan signifikan dengan prognosis pasien (P=0,12; OR=9; 95%CI=0,6-123).
      Kesimpulan: Ekspresi mRNA GLUT-1 dan VEGF-A berkorelasi positif dan saling mempengaruhi satu dengan lainnya. Peningkatan ekspresi mRNA GLUT-1 berhubungan dengan prognosis buruk pasien. Hasil penelitian ini mengindikasikan bahwa ekspresi mRNA GLUT-1 dari sampel darah berpotensi sebagai biomarker prognosis pada pasien kanker rektum yang menjalani kemoradiasi. Kata kunci: kanker rektum, kemoradiasi, GLUT-1, VEGF-A, prognosis

      Background: Rectal cancer patients have 40 percent risk of recurrence and resistance, which is triggered by increasing in GLUT-1 and VEGF-A mRNA expression. This condition associate with the patients prognosis. This study aimed to determine the correlation between GLUT-1 and VEGF-A mRNA expression, and analyze its association with the rectal cancer patients prognosis who received chemoradiation.
      Methods: This was a Cohort study involving 16 rectal cancer patients with stage II or III undergoing chemoradiation at Kariadi Hospital Semarang. Five milliliters of intravenous blood samples were taken before and after chemoradiation. Total RNA was isolated from 200 μl of blood serum, followed by cDNA synthesis. GLUT-1 and VEGF-A mRNA expression was quantified by the Livak method using β-actin as a reference gene.
      Results: GLUT-1 and VEGF-A mRNA expression decreased significantly 2.14 times (P=0,044) and 1,9 times (P=0,03), respectively. Expression of GLUT-1 and VEGF-A mRNA have a significant and strong positive correlation at before (r=0,6; R2=0,455; P=0,013) and after chemoradiation (r=0,8; R2=0,598; P<0,001). GLUT-1 mRNA expression enhancement significantly associate with poor prognosis and risk 18 times of worse prognosis (P=0,036; OR=18, 95% CI=1,2–261). VEGF-A mRNA expression did not associate with patient prognosis (P=0,12; OR=9; 95%CI=0,6-123).
      Conclusion: Expression of GLUT-1 and VEGF-A mRNA have a significant and strong positive correlation. GLUT-1 mRNA expression enhancement significantly associate with the poor prognosis of the rectal cancer patients. Our finding suggests that GLUT-1 mRNA expression from blood sample was potential as a biomarker to predict rectal cancer patient prognosis who received chemoradiation Keywords: rectal cancer, chemoradiotherapy, GLUT-1, VEGF-A, prognosis
