Karakteristik Pasien Usia Lanjut Di Ruang Rawat Intensif Rumah Sakit Immanuel Bandung

Peningkatan jumlah penduduk berusia lanjut sudah menjadi fenomena global. Usia lanjut diperkirakan berhubungan dengan peningkatan angka mortalitas di ruang rawat intensif (ICU). Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang berhubungan dengan outcome pasien usia lanjut di ICU. Penelitian ini menggunakan desain potong lintang yang dilakukan di ICU Rumah Sakit Immanuel, Bandung selama periode 1 Agustus 2009 hingga 31 Januari 2010. Penelitian ini mendapatkan karakteristik pasien usia lanjut di ICU: pasien pria lebih banyak (61%), diagnosis penyakit jantung paling banyak didapatkan (34%), dan 59% pasien memiliki hasil rawat membaik. Rata-rata biaya yang dihabiskan dari keseluruhan pasien adalah Rp. 13.856.131,25. Besarnya biaya rawat tidak menjamin hasil rawat yang baik. Faktor-faktor yang berhubungan dengan hasil rawat pasien usia lanjut (60 tahun atau lebih) yang dirawat ICU karena indikasi non bedah diidentifikasi sesuai dengan kuesioner yang telah dibuat. Hasil penelitian menunjukkan bahwa dari 132 pasien, pasien dengan usia ≥80 tahun memiliki hasil rawat memburuk (60,9%) lebih banyak dibandingkan membaik (39,1%). Pasien dengan status fungsional Activities of Daily Living (ADL) <10 yang memiliki hasil rawat memburuk (53,3%) lebih banyak dibandingkan hasil rawat membaik (46,7%). Pasien dengan lama rawat 0-1 hari atau >7 hari yang memiliki hasil rawat memburuk (48,14%) lebih banyak daripada hasil rawat membaik (20,5%). Simpulan penelitian adalah bahwa faktor-faktor yang mungkin mempengaruhi hasil rawat pasien usia lanjut di ICU adalah usia ≥80 tahun, status fungsional ADL ≤10, dan lama rawat 0-1 hari atau >7 hari

Field induced quantum-Hall ferromagnetism in suspended bilayer graphene

We have measured the magneto-resistance of freely suspended high-mobility bilayer graphene. For magnetic fields $B>1$ T we observe the opening of a field induced gap at the charge neutrality point characterized by a diverging resistance. For higher fields the eight-fold degenerated lowest Landau level lifts completely. Both the sequence of this symmetry breaking and the strong transition of the gap-size point to a ferromagnetic nature of the insulating phase developing at the charge neutrality point.Comment: 7 pages, 5 figure

Analisis Proses Cluster Formation Pada Cluster Based Simple Highway Mobility Model (Cbshwm) Di Jaringan 802.11p (Studi Kasus: Jaringan Yang Menggunakan Routing Protocol Aodv Dan Cblr)

Vehicular Ad Hoc Network (VANET) adalah jaringan yang terdiri dari sekumpulan wireless mobile node yang saling berkomunikasi tanpa infrastruktur yang tetap. Pada VANET dikembangkan suatu teknologi wireless untuk sistem komunikasi Vehicle to Vehicle (V2V) dan Vehicle to Road Side Unit (V2R). Komunikasi V2V dapat menggunakan konsep cluster yang disebut CBSHWM. Pada VANET kepadatan vehicle dan kecepatan gerak dari vehicle dapat mempengaruhi performansi dari jaringan. Jika terjadi kepadatan vehicle akan menimbulkan delay pada saat pengiriman paket ke vehicle tujuan. Selain itu, jika vehicle melaju dengan kecepatan tinggi maka akan menyebabkan perpindahan vehicle yang dapat menyebabkan kendala pertukaran paket data di jaringan. Penelitian ini bertujuan menganalisis performansi dua buah cluster formation yaitu cluster formation weight-based dan cluster formation CBLR pada jaringan VANET. Pemodelan jalan tol digunakan untuk menguji skenario kepadatan node dan kecepatan node. Evaluasi kinerja cluster formation weight-based dan CBLR ditinjau dari parameter cluster overhead, normalized cluster load, packet delivery ratio, packet loss rate dan cluster convergence time. Setelah dilakukan analisis dapat diketahui bahwa cluster formation CBLR lebih baik untuk kondisi jaringan berkecepatan tinggi dan kepadatan nodenya tinggi. Pada skenario Perubahan kepadatan node untuk jumlah node 40 didapatkan bahwa nilai packet delivery ratio cluster formation CBLR 99,86 %, sedangkan packet delivery ratio cluster formation weight-based 83,12 %. Skenario pengaruh Perubahan kecepatan node pada kecepatan 100 km/jam didapatkan bahwa nilai packet delivery ratio cluster formation CBLR 75,06 %, sedangkan packet delivery ratio CWeight sebesar 57,96 %

Molecular dynamics study of accelerated ion-induced shock waves in biological media

We present a molecular dynamics study of the effects of carbon- and iron-ion induced shock waves in DNA duplexes in liquid water. We use the CHARMM force field implemented within the MBN Explorer simulation package to optimize and equilibrate DNA duplexes in liquid water boxes of different sizes and shapes. The translational and vibrational degrees of freedom of water molecules are excited according to the energy deposited by the ions and the subsequent shock waves in liquid water are simulated. The pressure waves generated are studied and compared with an analytical hydrodynamics model which serves as a benchmark for evaluating the suitability of the simulation boxes. The energy deposition in the DNA backbone bonds is also monitored as an estimation of biological damage, something which is not possible with the analytical model

Left atrial appendage automatic segmentation, in computed tomography images

The left atrial appendage is one of the anatomical places where most frequently blood thrombi occur. When migrating from the appendage, these thrombi, become blood emboli that, potentially, can compromise the physiology and/or anatomy of cardiac or cerebral blood vessels, being able to generate cerebrovascular events. The left atrial appendage segmentation is very difficult due, mainly, to its location and the identical densitometric information presents into of this appendage and around of the left atrium. In this paper, an automatic technique is proposed to segment this appendage with the purpose of generating important information to the procedure called left atrial appendage surgical closure. This information is linked to the volume and the diameters of the left atrial appendage. The technique consists of a digital pre-processing stage, based on filtering processes and definition of a region of interest and, of one segmentation stage that considers a clustering method. The results are promising and they allow us to calculate useful quantitative variables when characterizing the most lethal appendix of the human body represented by the mentioned appendage. These results are very important in clinical processes where both the shape and volume of this appendage are vital for detecting and monitoring some vascular diseases such as cardiac embolism, arterial hypertension and stroke, among others
