Intrahepatic Cholestasis of Pregnancy with Severe Elevation of Bile Acids in the Setting of Acute Hepatitis C Infection

Intrahepatic cholestasis of pregnancy (ICP) is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L. She received ursodeoxycholic acid and antenatal testing was performed. Patient delivered vaginally at 33-week gestation following preterm rupture of membranes. Neonates were admitted to NICU and had uncomplicated neonatal courses. In the setting of ICP with significant transaminitis and severe elevation of bile acids, consideration of acute viral hepatitis is important, especially considering the worsening opioid epidemic and concurrent increase in intravenous drug use in the United States. Further study is needed regarding the acute form of HCV infection and its effect on ICP and associated bile acids

Studi Instrumen Kebijakan Gerakan Terpadu Kesehatan, Ekonomi, Pendindikan, Lingkungan, Infrastuktur (Gerdu Kempling) Kelurahan Bulusan Kota Semarang

An integrated movement of health, economic, education, infrastucture, enviroment (GERDU KEMPLING) program in Semarang is a policy about accelerating proverty reduction and the real action of “Sapta Program” from Semarang Goverment. The policy has a goal for reaching the decreacing of proverty's level in 2011 – 2015 at Semarang. In the first idea, it has been planned that the policy would invite all sectors in Semarang, including private sectors and the citizen. Then a policy can be applied well, if it uses a correct policy instrument in its implementation. And in this research, it will discuss about which one of policy instrument that has been used in Gerdu Kempling program. The result shows in implementing this policy, the actors use mixed instrument, and more head for subsidies instrument. It's proved by there are mixturing among regulation from compulsary instrument and family and community and market from voluntary instrument. After that, the subsidies instrument can be proved by types of help that have been given to poor citizen, which are coaching and tools. In other hand, in implementing this policy with mixed instrument has some problems in it. Over all, the problems are about support instruments have not maximal in their action

Penentuan Kriteria Nutrien Untuk Penilaian Status Trofik Perairan Waduk Mrica Banjarnegara, Indonesia (Determination of Nutrient Criteria for Assessing Trophic Status of Mrica Reservoir Banjarnegara, Indonesia)

Saat ini kriteria nutrien yang sering digunakan untuk penilaian status trofik suatu badan air di Indonesia adalah berdasarkan OEeD (1982), dan Mason (1991) yang merupakan hasil kajian status trofik danau dan waduk di wilayah empat musim (temperate). Kriteria tersebut bila digunakan untuk waduk di Indonesia sering tidak mencerminkan kondisi yang sebenamya karena ada perbedaan mekanisme terjadinya eutrofikasi di wilayah tropis dan temperate (Huszar et al., 2006). Tujuan peneiitian ini adalah mengkaji hubungan antara konsentrasi nutrien dengan biomassa algae sebagai dasar untuk menentukan kriteria nutrien yang tepat sebagai upaya penentuan kriteria trofik waduk di Indonesia. Metode peneiitian menggunakan survei dengan mengambil sampel air sebulan sekali selama 1 (satu) tahun mulai Maret 2009 -Februari 2010 di 11 (sebelas) lokasi di perairan Waduk Mrica Banjamegara. Variabel penelitian adalah Total Nitrogen (TN), Total Fosfat (TP), nitrat (NO]), ortofosfat (P04), ammonia ~), TN/TP, dan klorofil. Kesimpulan adalah kriteria TP untuk mencapai fase eutrofik pad a musim penghujan lebih tinggi (TP ~ 1,55 mg/I) dibandingkan musim kemarau (TP ~ 1,33). Pada musim penghujan maupun kemarau total nitrogen (TN) bukan merupakan nutrien pembatas. Nutrien (N dan P) yang tinggi (bahkan mencapai 10 kali iipat lebih tinggi dibandingkan kriteria nutrien dari wilayah temperate) tidak menirnbulkan blooming. Terjadinya blooming algae di Waduk Mrica disebabkan adanya operasional waduk dan didukung oieh kondisi iklim (cahaya dan suhu) yang tidak menjadi faktor pembatas pertumbuhan algae. Oleh karena itu, kriteria nutrien untuk danau di wilayah sub tropis tidak cocok bila digunakan untuk penilaian status trofik untuk waduk di Indonesia

Tingkat Pencemaran Waduk Penjalin Kecamatan Paguyangan Kabupaten Brebes Ditinjau dari Struktur Komunitas Plankton

Penjalin Reservoir is located in Brebes Regency, Indonesia. Human activity around Penjalin Reservoir, such as irrigation, aquaculture, and sanitation can affect its water\u27s quality. Plankton can be used as bioindicator since its existence is heavily affected by water physical and chemical factors. Polluted waters can affect diversity and abundance of plankton. The purpose of this research were to determine waters quality of Penjalin Reservoir, to know plankton community structure (abundance, diversity, and domination), and pollution level of each sampling station based on plankton diversity. This research used survey method on 6 sampling stations covering inlet, middle of reservoir, and outlet with 3 replicates and 4 weeks interval. Water quality were analyzed descriptively based on criteria of PP No. 82 Tahun 2001. Abundance and diversity were estimated as Shanon-Wiener index. Domination were estimated as Simpson index. Plankton abundance values varies from 4,970.30 to 12,923.37 ind/l with the most abundant species was Tetraedon minimum. Diversity index (H\u27) were high with value around 3.28–3.55 and domination index were around 0.04–0.07. These diversity indexes showed that the water quality of Penjalin Reservoir were not polluted
