To assess the effect of clinical pharmacists in daily audits, under the direction of an antimicrobial stewardship program, of antibiotic treatment durations for the common inpatient disease states of ...community-acquired pneumonia (CAP) and urinary tract infection (UTI).
This was a retrospective single-center cohort study that evaluated the difference in the duration of antibiotic therapy for CAP or non–catheter-associated UTI of hospitalized patients who received a daily audit by clinical pharmacists compared with patients who did not receive a daily audit. Retrospective chart review included randomly selected hospitalized patients diagnosed with CAP or UTI during preaudit and postaudit periods.
The preaudit group had 64 patients; and the postaudit group, 51 patients. The therapy duration was 7 days in the preaudit group and 6 days in the postaudit group (P=.55). Fluoroquinolone use was reduced in the postaudit group and was significantly less than in the preaudit group (24 37.5% vs 7 13.7%; P=.007).
The daily audits of clinical pharmacists may be an effective method to reduce the duration of antibiotic therapy and are effective in the reduction of fluoroquinolone use. Additional studies must be done to further investigate the effects of clinical pharmacist antimicrobial stewardship efforts.

The measurement of the magnetic field in the tracking volume inside the superconducting coil of the Compact Muon Solenoid (CMS) detector under construction at CERN is done with a fieldmapper designed ...and produced at Fermilab. The fieldmapper uses 10 3-D B-sensors (Hall probes) developed at NIKHEF and calibrated at CERN to precision 0.05% for a nominal 4 T field. The precise fieldmapper measurements are done in 33840 points inside a cylinder of 1.724 m radius and 7 m long at central fields of 2, 3, 3.5, 3.8, and 4 T. Three components of the magnetic flux density at the CMS coil maximum excitation and the remanent fields on the steel-air interface after discharge of the coil are measured in check-points with 95 3-D B-sensors located near the magnetic flux return yoke elements. Voltages induced in 22 flux-loops made of 405-turn installed on selected segments of the yoke are sampled online during the entire fast discharge (190 s time-constant) of the CMS coil and integrated offline to provide a measurement of the initial magnetic flux density in steel at the maximum field to an accuracy of a few percent. The results of the measurements made at 4 T are reported and compared with a three-dimensional model of the CMS magnet system calculated with TOSCA.

The Fermilab Large Cold Blackbody Test Stand can be used to expose a microwave receiver and horn assembly to a large blackbody at cryogenic temperatures (as low as 20K). The temperature of the ...blackbody can be varied while keeping the receiver temperature constant, facilitating Y-factor measurements of the receiver noise temperature and gain. The test stand has recently been used for studying a QUIET-I receiver module. The test stand will be used to measure both QUIET-I and prototype QUIET-II modules.

Presented are the main design features of the large cathode strip chambers (CSCs) for the CMS endcap muon system as well as the performance results obtained with the first large-scale prototype. The ...3.4×1.2m2 six-plane prototype has been reliably operated over one year and the cosmic-ray tests showed that it was capable of detecting muons with ∼80μm spatial and ∼5ns time resolutions.

Presented are the main design features and performance results of the Cathode Strip Chambers for the CMS Endcap Muon system. Although the strips are unusually wide (up to
16
mm
) for the ...cathode-to-anode wire distance of
5
mm
, the six-plane structure of these chambers yields a spatial resolution of about
80
μm
, essentially uniform and independent of the strip width. In addition, the net spatial resolution of about one-tenth of the strip width at the hardware trigger level
(300
ns)
is obtained using a simple network of comparators. Time resolution achieved at the trigger level is
∼4
ns
(rms) that allows unambiguous tagging of bunch crossings which occur every
25
ns
. Aging test results, including those obtained with a recirculating gas system, are discussed; only minor aging affects were observed. The aging studies were performed with large-scale chambers;
700
m
of wire were irradiated for a dose up to
0.4
C/
cm
of the total accumulated charge.

Presented are the main design features of the large Cathode Strip Chambers (CSCs) for the CMS Endcap Muon System as well as the performance results obtained with the two full-scale 3.4×1.5 m
2 ...six-plane prototypes. The prototype performance was within the baseline requirements: (a) higher than 99% efficiency of muon track finding at the trigger level with more than 92% probability for bunch crossing identification and better than 2
mm spatial resolution, and (b) better than 150
μm spatial resolution in off-line.
