Hemodynamic Effects of Intravenous Calcium Administration on Septic Shock Patients:A Retrospective Study

We evaluated the hemodynamics and outcomes of septic shock (SS) patients who did not respond to fluid resuscitation, after treatment with or without intravenous calcium. We retrospectively collected information on 154 eligible SS patients who were admitted to Fukuyama City Hospital Emergency Medical Center and did not respond to fluid resuscitation. To compare their degree of hemodynamic impairment, we compared the changes in the vasoactive-inotropic score (VIS) in the calcium-treated group (n＝112) and the noncalcium-treated group (n＝42). We compared the length of stay in the intensive care unit (ICU) and hospital, in-hospital deaths, 28-day deaths, and changes in the Sequential Organ Failure Assessment score within 72h of ICU admission between the 2 groups. Changes in the VIS at 1h after the baseline time were significantly greater in the calcium-treated group than in the noncalcium-treated group (1.41 vs. －1.25, respectively;p＜0.001). However, the changes in the VIS at 3, 6, 24, 48, and 72h did not differ between the 2 groups. The secondary outcomes also did not differ between the groups. Our findings indicate that calcium administered to SS patients might reduce their hemodynamic stabilization, but only for a short time after its administration

Emission Spectra of Pyridine, Tetrahydrofuran, Thiophene, Thiophenol and Ethanethiol by Controlled Electron Impact

Bands of only fragment species (H, CH, CN, CO, CO^+, C_2, CS, CS_2^+, SH^+, C_4H_2^+) were observed in the spectra (220-550 nm) under electron impact excitation except for thiophenol, which showed a board band of parent species in the 260-330 nm region. The emission intensities of CN, CO and CO^+, which have to be produced with the scission of two skeletal bonds, showed non-linear dependence on the electron-beam current

Two Micron Pixel Pitch Active Matrix Spatial Light Modulator Driven by Spin Transfer Switching

We have developed an active matrix-addressed magneto-optical spatial light modulator driven by spin-transfer switching (spin-SLM) which has a 100 × 100 array pixel layout with a 2 µm pixel pitch. It has pixel-selection-transistors and logic circuits which convert serial data into parallel data to reduce input terminals. We have confirmed successful magnetization switching of each pixel by injecting a pulse current generated from the logic circuit, and its optical display capability by showing digital characters
