A technique is described for the subcutaneous deviation of the carotid artery into the jugular groove of calves weighing between 90 and 200 kg. This makes sampling arterial blood or chronic cannulation for further experimentation very easy. Values of oxygen tension, carbon dioxide tension, pH and bicarbonate concentration in blood sampled from the ventral coccygeal artery were compared with the values obtained in blood from carotid artery puncture. The high correlations observed indicate that blood samples from the ventral coccygeal artery can be used for measurement of blood gases and pH in calves. [less ▲]

Genomes of herpesvirus aotus type 2 (HVA-2) and bovine herpesvirus type 4 (BHV-4) have previously been shown to be closely similar. Moreover, preliminary serological data indicated that HVA-2 is antigenically related to BHV-4. To extend this study, structural components of four BHV-4 strains and HVA-2 were compared by SDS-PAGE, radioimmunoprecipitation and Western blotting. The overall pattern of structural proteins was the same for HVA-2 and BHV-4 but variations were observed in electrophoretic profiles of glycoproteins, mainly of the two major ones (gp6/gp10/gp17 and gp11/VP24). Variations between HVA-2 and BHV-4 glycoproteins were greater than those observed among BHV-4 strains. [less ▲]

Objective-To describe the magnetic resonance imaging (MRI) appearance of medial coronoid process and humeral condyle lesions in dysplastic cubital joints and to compare survey radiography and MRI for evaluation of fragmented medial coronoid process (FMCP) and lesions of the medial aspect of the humeral condyle (MAHC). Animals-18 dogs with elbow dysplasia. Procedure-Radiography of 22 cubital joints was performed. The 22 joints then underwent MRI. The scans were evaluated with regard to the shape and signal of the coronoid process; articular cartilage change, subchondral bone disruption of the MAHC. Surgical findings were used as the standard to calculate accuracy, sensitivity, specificity, and positive-and negative-predictive values for specific diagnosis of FMCP (free fragment) and lesions of the MAHC. Results-At surgery, 31.8% of the joints had FMCP (free), 36.4% had nondisplaced unmineralized coronoid process, and 27.2% had nondisplaced mineralized coronoid process, Eleven joints had lesions of the MAHC, and wear lesions were observed in 41% of the joints. On radiography, FMCP (free) was visualized in 9% of the joints and lesions of the MAHC were observed in 23%. MRI had the highest accuracy (95.5%), sensitivity (100%), and negative-predictive value (100%) for detection of FMCP (free), and had accuracy (91%), sensitivity (87.5%), specificity (92.5%), and positive (87.5%)- and negative (92.5%)- predictive values for detection of nondisplaced unmineralized coronoid process. Conclusions and Clinical relevance-Compared with radiography, MRI was useful for detection of nondisplaced unmineralized coronoid process; images consistently correlated with surgical findings. The technique is accurate and especially useful when radiographic findings are inconclusive. [less ▲]

Assessment of disease severity is most often made visually, and estimates can be inaccurate. Nearest percent estimates (NPEs) of Septoria leaf blotch on leaves of winter wheat by four raters (R1-R4) assessing non-treated (NT) and fungicide-treated (FT) plots were compared to true values using Lin’s concordance correlation coefficient (ρc) on two dates in 2006 and 2007. Estimates were converted to Horsfall-Barratt (HB) mid-points and again compared for accuracy and precision. Estimates of severity from FT and NT plots were analyzed to ascertain effects of rater using both the NPE and HB values. Regardless of method, all raters showed a range of agreement with true values on FT and NT plots (ρc = 0 to 1). Use of the HB scale most often reduced agreement (84.4% of the time), and did not improve rater-associated bias of treatment mean severity estimates. Consequently, estimates of mean severity differed significantly among raters and from true values (F=126 to 1260, P=0.002 to<0.0001). However, a comparison of treatment effects showed that the true values and R1 to R4 all demonstrated significant effects of fungicide (F=101 to 1952, P=0.002 to <0.00001). Ranking of raters differed on one occasion when HB values were used. These results demonstrate the effect of the HB scale, and the need for accurate disease assessment to minimize over or underestimates compared to true severity so as to minimize the potential for type II errors.

Objectives. Because of low sensitivity of fungal cultures and lack of standardization of Aspergillus PCR, laboratory diagnosis of invasive aspergillosis still relies on galactomannan (GM) detection in broncho-alveolar lavage (BAL) fluids and serum. The aim of this study was double: first, to assess the place of a 18S rRNA Aspergillus real-time PCR test performed in BAL fluid for the diagnosis of invasive aspergillosis (IA) in neutro- and non-neutropenic patients in comparison with GM detection; secondly, to evaluate the use of three different GM cut-off values. Materials and methods. A total of 111 neutropenic and non-neutropenic patients hospitalized at the University hospital of Liège from March to October 2012 with suspicion of IA were included in the study. A total of 138 broncho-alveolar lavage fluids were evaluated by three laboratory diagnostic methods: 1/ culture on Sabouraud agar slants with antibiotics (bioMérieux, France) incubated at 28°C for 28 days; 2/ GM detection (Platelia ™Aspergillus EIA, Biorad) using GM index cut-off values at 0.5, 0.8 and 1, performed three times a week; 3/ a real-time Aspergillus PCR assay performed daily and targeting the 18S rRNA genes by using an in-house method. Clinical, radiological and microbiological data were reviewed for classification of patients. Results. Nine patients developed probable or possible IA. The sensitivity/specificity/positive (VPP) and negative (NPV) predictive values (%) for culture, PCR, and GM using 0,5 as cut-off value were respectively 41/100/100/94, 58/97/70/96, and 91/83/34/99. The use of 0,8 and 1 as GM index cut-off values increased the specificity to 89 and 92% respectively, and the VPP to 44 and 54%. PCR had a better turn-around time and allowed the detection of Aspergillus colonisation. Conclusion: GM detection in BAL fluids using a cut-off value of 1 was the most efficient laboratory test for the diagnosis of IA in neutropenic and non-neutropenic patients. Despite a lower sensitivity, PCR had a better VPP, and allowed the detection of culture-negative Aspergillus colonisations. A shorter turnaround time (TAT) due to daily practice of PCR tests may reduce the time-to-treatment up to 24 hours. [less ▲]

OBJECTIVES: To assess the agreement between infrared emission detection (IRED) ear and rectal temperatures and to determine the validity of IRED ear thermometry in detecting rectal fever. DESIGN: Prospective, convenience sample, unblinded study. SETTING: An acute geriatric unit (teaching hospital) and a multidisciplinary intensive care unit. PARTICIPANTS: The study included 45 inpatients (26 women and 19 men), aged 78.3+/-6.9 years, admitted over a 4-month period. Twelve of the patients were definitely infected. MEASUREMENTS: Sequential rectal (RT) and ear temperature (ET) measurements were performed using mercury-in-glass and IRED ear thermometers, respectively. IRED ear temperatures were measured at both ears (unadjusted mode), with the highest of six ear temperatures considered the true value. RESULTS: Mean RT (37.39 degrees C +/- 0.52 degrees C) was significantly (P<.001) higher than mean ET (36.89 degrees C +/-0.59 degrees C). A highly significant positive correlation was found between RT and ET (slope = 0.69; 95% CI, 0.52-0.86; P<.001; r = 0.78). The mean bias (mean of the differences) between RT and ET was 0.50 degrees C +/-0.37 degrees C (95% CI, 0.41 degrees C-0.59 degrees C), and the 95% limits of agreement -0.22 degrees C and 1.23 degrees C (95% CI, -0.38 degrees C to 1.39 degrees C). According to the standard criterion (RT > or =37.6 degrees C), 14 patients were febrile. Using an optimum IRED ear fever threshold (37.2 degrees C), the sensitivity and specificity of IRED ear thermometry for predicting rectal fever were 86% and 89%, respectively (positive predictive value, 80%; negative predictive value, 93%). CONCLUSIONS: The degree of agreement between rectal temperature and the highest of six IRED ear temperatures was acceptable. Using an optimal IRED ear fever threshold of 37.2 degrees C (99 degrees F), IRED ear thermometry had acceptable sensitivity and specificity for predicting rectal fever. [less ▲]

Experimental dynamic substructuring is a means whereby a mathematical model for a substructure can be obtained experimentally and then coupled to a model for the rest of the assembly to predict the response. Recently, various methods have been proposed that use a transmission simulator to overcome sensitivity to measurement errors and to exercise the interface between the substructures; including the Craig-Bampton, Dual Craig-Bampton, and Craig-Mayes methods. This work compares the advantages and disadvantages of these reduced order modeling strategies for two dynamic substructuring problems. The methods are first used on an analytical beam model to validate the methodologies. Then they are used to obtain an experimental model for structure consisting of a cylinder with several components inside connected to the outside case by foam with uncertain properties. This represents an exceedingly difficult structure to model and so experimental substructuring could be an attractive way to obtain a model of the system. [less ▲]

A computerized program was written to collect, evaluate and compare reproductive performance data of 2004 beef (Belgian Blue breed) and 1649 dairy (Friesian Holstein and German Red) cattle in 35 Belgian herds (6 suckler beef herds, 9 milked beef herds and 20 dairy herds). Reproduction data were collected at monthly herd health visits. No difference in age at first calving was observed. Significant differences were observed among the 3 kinds of herds, and the best results were obtained in dairy herds for the calving interval, interval from calving to the first estrus, interval from calving to the first service and average number of days open. Concerning these parameters, first calvers had lower results than multiparous cows, mainly in suckler and milked beef herds. Significant differences were noted in the number of services per pregnancy. Heifers that had never calved presented the highest fertility. Primiparous beef cows had higher fertility than pluriparous cows. In dairy herds, pluriparous cows had higher fertility than primiparous cows. Estrus detection was better in milked beef herds than in suckled beef and dairy herds. Suckled beef herds had the lowest incidence of metritis and ovarian cysts of the three types of herds. Rates of abortion, overall culling and retained fetal membranes were similar in all the herds. The percentage of animals removed for infertility was highest in milked beef herds and lowest in dairy herds. Because 90% of the 1159 calvings recorded in the beef herds required a caesarean section, the reproductive performance of beef cattle represent results after caesarean section. [less ▲]
