Update on the Diagnosis of Gestational Trophoblastic Disease
Get PDFPenyakit trofoblas gestasional (PTG)/Gestational trophoblastic disease (GTD) terdiri dari kelompok mola hidatidosa yang terbagi menjadi komplit dan parsial, hingga kelompok Tumor trofoblas gestasional (TTG)/Gestational trophoblastic neoplasia (GTN) yang terdiri dari mola invasif, koriokarsinoma, dan placental site trophoblastic tumour/epithelioid trophoblastic tumour (PSTT/ETT). TTG dikategorikan menjadi dua yaitu yang tidak bermetastasis (hanya terbatas di uterus) dan yang bermetastasis (telah menyebar ke vagina, paru-paru atau otak). Penegakan diagnosis inisial PTG melalui pendekatan multimodalitas mencakup gejala klinis, kadar hCG dan pemeriksaan USG pelvis. Doppler membantu menilai angiogenesis dan karakterisitik neovaskularisasi PTG. Gambaran yang tampak pada USG akan menjelaskan gambaran pada histopatologinya. Pemeriksaan penunjang lain untuk PTG adalah rontgen thoraks, CT Scan dan MRI. Saat ini pemeriksaan imunohistokimia (IHK) dan polymerase chain reaction (PCR) sudah mulai digunakan untuk menentukan diagnosis PTG. Pemantauan hCG mempunyai peran penting dalam penatalaksanaan PTG. Tetapi karena terdapat beberapa pedoman yang menyatakan protokol berbeda-beda dalam pemantauan hCG, hal ini membuat para dokter spesialis obgin mempertanyakan mengenai pemantauan hCG pasca evakuasi. Himpunan Onkologi Ginekologi Indonesia mengeluarkan suatu Pedoman Nasional Pelayanan Kedokteran (PNPK) Tumor Trofoblas Gestasional yang didalamnya terkait diagnosis dan penatalaksaan TTG
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Diagnosis Prenatal Hidronefrose dengan Ultrasonografi (laporan kasus)
Get PDFTujuan: Melaporkan 2 kasus hidronefrose yang didiagnosis dengan
pemeriksaan USG pada masa prenatal.
Hasil: Dua kasus hidronefrose yang didiagnosis dengan ultrasonografi.
Kasus 1, hidronefrose didiagnosis pada usia kehamilan 32 -
33 minggu, didapatkan jenis kelamin perempuan dengan hidronefrose
bilateral. Pada evaluasi postnatal dengan USG didapatkan kesan hidronefrose
kanan moderat. Kasus 2, hidronefrose didiagnosis pada usia
kehamilan 25 minggu, didapatkan jenis kelamin laki-laki dengan hidronefrose
bilateral, megavesika dan oligohidramnion. Persalinan kedua
kasus dengan bedah sesar pada kehamilan aterm. Bayi pertama normal.
Bayi kedua menderita sindrom Potter dan meninggal setelah 7 jam
karena pneumothorax.
Kesimpulan: Kelainan yang mengenai ke dua ginjal (bilateral) lebih
berbahaya dari pada kelainan yang mengenai satu ginjal (unilateral).

HUBUNGAN KADAR KORTISOL DAN PROSTAGLANDIN MATERNAL DENGAN PERSALINAN PRETERM DAN ATERM
Get PDFPenelitian ini merupakan penelitian Observasional dengan desain penelitian cross-sectional. Penelitian dilakukan di RSUD dr. Rasidin Padang, RSUD. Prof. Dr. MA Hanafiah SM Batusangkar, RSUP. M. Djamil, dan BPS. Nurhaida, Amd.Keb pada bulan September 2017 sampai Januari 2018. Jumlah sampel sebanyak 50 responden yang dipilih secara consecutive sampling yang dibagi menjadi 2 kelompok. Pemeriksaan kadar kortisol dan prostaglandin dilakukan di Laboratorium Biomedik Universitas Andalas Padang dengan metode ELISA. Terdapat hubungan bermakna antara kadar kortisol dengan persalinan preterm dan aterm (p= 0,02; p 0,05). Kata Kunci: Kortisol, Prostaglandin, Persalinan Preter
PENGARUH PAPARAN ASAP ROKOK TERHADAP KADAR ZINK DAN KORTISOL PADA TIKUS PUTIH HAMIL (RATTUS NORVEGICUS)
Get PDFPenelitian ini merupakan penelitian Eksperimen dengan desain penelitian post test only control group design Penelitian dilakukan di lab farmasi unand, pada bulan Juni sampai dengan agustus 2018. Pengambilan sampel dilakukan dengan simple random sampling (acak sederhana), Jumlah sampel sebanyak 28 ekor dibagi menjadi 4 kelompok, kelompok 1 sebagai kontrol penelitian, kelompok 2 diberikan perlakuan 1 batang rokok, kelompok 3 diberikan perlakuan 2 batang rokok dan kelompok 4 diberikan perlakuan 3 batang rokok. Pemeriksaan kadar zink dan kadar kortisol dilakukan di Laboratorium Biomedik Universitas Andalas Padang dengan metode ELISA. Tidak terdapat perbedaan bermakna antara paparan rokok dengan kadar zink (p= 0.32) maka, (p > 0,05). Dan tidak terdapat perbedaan paparan asap rokok dengan rerata kadar kortisol (p = 0,146) maka, ( p > 0,05). Kata Kunci: asap rokok, zink, kortiso
