The quality of fit of a trans-tibial patellar-tendon-bearing (PTB) socket may be influenced by consistency in casting, rectification or alignment. This paper quantifies, for the first time, the variations in the rectified casts between two experienced prosthetists and the variation between the rectified casts of each individual prosthetist. Prosthetists A and B observed the hand casting of a typical trans-tibial amputee. Each prosthetist was supplied with 5 previously measured duplicated plaster models. The two prosthetists rectified the supplied plaster models based on their own interpretation of basic rectification guidelines. Both prosthetists operated in isolation. The re-measured rectified plaster model data was compared with the unrectified data. The extent of rectification at each of 1800 locations per plaster model was calculated. In zones of major rectification, the mean difference between prosthetists was quantified as 2mm and the standard deviation (SD) about that mean was ±1mm for each prosthetist. The co-ordinates of the apex of the fibular head for the 10 modified casts indicated that the maximum variation was in the axial direction with a SD of 4.3mm for prosthetist A and a SD of 2.8mm for prosthetist B. The lengths of the 5 plaster models rectified by prosthetist A indicated a SD of 0.2mm whereas the lengths of the 5 plaster models rectified by prosthetist B indicated a SD of 2.9mm.

The quality of fit of a transtibial patellar tendon bearing (PTB) socket may be influenced by consistency in casting, rectification or alignment. For this study two distinctive different datacapturing concepts were tested in relation to prosthetist performance. The handson PTB and handsoff ICECAST compact® concept were studied and compared for inter and intraprosthetist consistency using a specially designed manikin stump model. A purpose designed digitiser was used to scan a selected surface area of the produced models, 5 for each concept, 10 in total. The extent of casting consistency at each of 936 locations per plaster model was calculated and the level of consistency was quantified. This study has shown that by using the manikin model there is a clear indication that the investigated handsoff concept produces more consistent results than the handson concept.

Abstract Background Stress echocardiography (SE) plays an important role among methods of noninvasive diagnosis of ischemic disease. Despite the advantages of physical exercise as the most physiologic stressor, it is difficult (bicycle ergometer) or impossible (treadmill) to obtain and maintain the acoustic window during the exercise. Recently, an innovative probe fixation device was introduced and a research plan was developed to assess the feasibility of external probe fixation during exercise echocardiography on a supine bicycle and upright treadmill exercise for the first time. Methods 37 subjects (36 men, mean age 39 ± 16 years, 21 healthy volunteers, 16 patients with suspected coronary artery disease) were included in this study. This preliminary testing stage included mostly men due to more problematic probe fixation in women. All subjects underwent a submaximal exercise stress test on a treadmill (17/37) or bicycle ergometer (11/37). Both sector and matrix probes were used. We assessed semi-quantitatively the quality of acquired apical views at each stage – the four-point grading system was used (0-no view, 1-suboptimal quality, 2-optimal quality, 3-very good quality), 2-3 sufficient for diagnosis. Results The mean time required for careful positioning of the probe and image optimization was 12 ± 3 min and shortened from 13,7 to 11,1 minutes (mean) in first vs second half of the cohort documenting learning curve. At baseline, 9 patients had at least one apical view of quality precluding reliable analysis. Those patients were excluded from further assessment. During stress, 17 patients maintained the optimal or very good quality of all apical views, whereas in 11 patients the quality significantly decreased during the stress test and required probe repositioning. The mean image quality score at baseline was 2,61 ± 0,48 and 2,25 ± 0,6 after exercise. Expectedly, good image quality was easier to obtain and maintain in the supine position (score 2,74 ± 0,44) points as compared with upright position (score 2,25 ± 0,57). Conclusion This preliminary, unique experience with external probe fixation device indicates that continuous acquisition and monitoring of echocardiographic images is feasible during physical exercise, and for the first time ever - also on the treadmill. This feasibility data stem from almost exclusively male patients and the estimated rate of sufficient image quality throughout the entire test is currently around 60%. We are hoping, that gaining more experience with the product could increase the success rate on exercise tests. Abstract P1398 Figure. Treadmill and ergometer stress test

Abstract. The Optical Spectrograph and InfraRed Imaging System (OSIRIS) on the Odin satellite is currently in its 12th year of observing the Earth's limb. For the first time, continuous temperature profiles extending from the stratopause to the upper mesosphere have been derived from OSIRIS measurements of Rayleigh-scattered sunlight. Through most of the mesosphere, OSIRIS temperatures are in good agreement with coincident temperature profiles derived from other satellite and ground-based measurements. In the altitude region of 55–80 km, OSIRIS temperatures are typically within 4–5 K of those from the SABER, ACE-FTS, and SOFIE instruments on the TIMED, SciSat-I, and AIM satellites, respectively. The mean differences between individual OSIRIS profiles and those of the other satellite instruments are typically within the combined uncertainties and previously reported biases. OSIRIS temperatures are typically within 2 K of those from the University of Western Ontario's Purple Crow Lidar in the altitude region of 52–79 km, where the mean differences are within combined uncertainties. Near 84 km, OSIRIS temperatures exhibit a cold bias of 10–15 K, which is due to a cold bias in OSIRIS O2 A-band temperatures at 85 km, the upper boundary of the Rayleigh-scatter derived temperatures; and near 48 km OSIRIS temperatures exhibit a cold bias of 5–15 K, which is likely due to multiple-scatter effects that are not taken into account in the retrieval.

The fourth national baseline microbiological survey of Australian beef was conducted in 2011, including frozen boneless beef and, for the first time, samples from selected beef primal cuts. Cartons of frozen boneless beef (n = 1,165) sampled at 29 boning (fabrication) plants were found to have a mean total viable count of 2.2 log CFU/g, and the mean count for the 2.1% of samples with detectable Escherichia coli was 1.3 log CFU/g. The mean total viable counts for striploins (longissimus dorsi, n = 572) and outsides (biceps femoris, n = 572) were 1.3 and 1.5 log CFU/cm2 respectively. E. coli isolates were obtained from 10.7 and 25.2% of striploins and outsides, respectively, with mean counts of −0.5 and −0.3 log CFU/cm2 on positive samples. E. coli O157:H7, Salmonella, and Campylobacter were not isolated from any primal cut samples, and Salmonella was not isolated from any of the boneless product (E. coli O157:H7 and Campylobacter were not tested for). Listeria spp. were not detected in any of the boneless product, and one Listeria isolate was obtained on 1 (0.2%) of 572 striploin samples. Coagulase-positive staphylococci were isolated from 3.4% of boneless beef samples, 7.7% of beef striploins, and 8.4% of beef outsides, with positive samples having mean log counts of 1.9 CFU/g, 0.2 CFU/cm2, and 0.2 CFU/cm2, respectively.

This work assessed the quality of wind speed estimates in Uruguay. These estimates were obtained using the Weather Research and Forecast Model Data Assimilation System (WRF-DA) to assimilate wind speed measurements from 100 m above the ground at two wind farms. The quality of the estimates was assessed with an anemometric station placed between the wind farms. The wind speed estimates showed low systematic errors at heights of 87 and 36 m above the ground. At both levels, the standard deviation of the total errors was approximately 25% of the mean observed speed. These results suggested that the estimates obtained could be of sufficient quality to be useful in various applications. The assimilation process proved to be effective, spreading the observational gain obtained at the wind farms to lower elevations than those at which the assimilated measurements were taken. The smooth topography of Uruguay might have contributed to the relatively good quality of the obtained wind estimates, although the data of only two stations were assimilated, and the resolution of the regional atmospheric simulations employed was relatively low.

Abstract Aging in vertebrates is an extremely complex process that is still poorly understood. One confining factor to studying vertebrate aging is the lack of appropriate models. The laying hen is a good model to study vertebrate aging, as it can be maintained under standard housing conditions, its breeds are genetically well defined and it exhibits significant aging phenotypes at around 18 months of age. Furthermore, laying hens are maintained in a challenging realistic environment and possess a fully functional immune system. Here we used, for the first time, metabolomic profiling of laying hens' blood for identifying biomarkers of aging. Random forest classifier was used to quantify the quality of the markers and found that the markers can predict the correct age group of individuals with 90% accuracy. Animals under time-restricted feeding, a condition known to increase healthspan, appeared younger under the markers, indicating that the aging biomarkers can also predict the effectiveness of environmental treatments. Additionally, we found that noise, defined as the ratio between the standard deviation and the mean, is an exceptionally robust and universal biomarker of aging, as metabolomic noise increases significantly with age in laying hens, humans, and mice. Our study suggests the laying hen as a useful model to study aging in vertebrates and establishes metabolomic noise as a novel, universal biomarker of aging.

Abstract Background The role of transthoracic echocardiography (TTE) in the intensive cardiac care unit is crucial. Imaging is currently performed at the bedside for diagnosis but TTE has also potential to noninvasively provide critical views to assist in patient monitoring. Continuous monitoring would be especially helpful when the patient is unstable; however, continuous availability of skilled sonographers to obtain appropriate views represents a limiting factor. Purpose Recently, an innovative external fixation device allowing prolonged stabilization of transthoracic ultrasound transducer was introduced. The ring-shaped device fitted for TTE probes is attached to the patient by elastic straps to hold the probe in contact with the skin at a fixed but adjustable angle. We developed a research project to assess for the first time the feasibility of continuous TTE imaging with external probe fixation in the intensive cardiac care unit. Methods 12 patients (10 men, mean age 66,5 ± 15 years) hospitalized in intensive cardiac care unit due to cardiac arrest, myocardial infarction, pulmonary embolism, end-stage heart failure or respiratory failure were included in the study. The echocardiographic probe be was fixed in the apical window providing a four-chamber view to monitor left ventricular function. We assessed the patient’s tolerance and comfort as well as the quality of images acquired at baseline and at the end of monitoring. Results Fixation of the probe was successful in all patients (figure 1). The mean time of fixation was 10 ± 1 minute, with a clear learning curve. The quality of obtained images was sufficient for evaluation and was maintained throughout the entire period of monitoring in all patients. Monitoring was stopped at patients’ request when discomfort caused by the compression of the skin by the probe and the fixation device became significant (figure 2). The mean duration of monitoring was 85 + 64 minutes (range 15 to 240 minutes). Conclusions In this preliminary series we have demonstrated for the first time the feasibility of echocardiographic continuous monitoring of patients in the intensive cardiac care unit using TTE probe with the external fixation device. The design of the fixation device opens the evident field for optimization to extend monitoring duration at acceptable levels of discomfort in conscious intensive care patients. We hope the improved version of the fixator will decrease the pressure on the body. Abstract P274 Figure. Fixation of the device

Abstract The most common evaluation criterion used by regulatory and voluntary interlaboratory proficiency testing (PT) programs to judge the quality of chemistry results is based on the group mean +/- 2.0 standard deviations (SD), the 1(2)s rule. The mean and SD are those of the selected PT population. Through computer simulations we have quantified, for the first time, the ability of the 1(2)s criterion to detect "acceptable" as well as substandard ("unacceptable") intralaboratory performance by PT. We found that the 1(2)s rule correctly identifies "acceptable" performance--i.e., low intralaboratory coefficient of variation (CV) values and small bias values--greater than 90% of the time. However, this criterion fails to detect laboratories with "unacceptable" bias and (or) CV at least 23% of the time. The high failure rate of the 1(2)s rule raises serious questions about its appropriateness for use by PT programs.

Purpose The shortage of doctor of philosophy (PhD)–level applicants to fill academic and research positions in communication sciences and disorders (CSD) programs calls for a detailed examination of current CSD PhD educational practices and the generation of creative solutions. The intended purposes of the article are to encourage CSD faculty to examine their own PhD program practices and consider the perspectives of recent CSD PhD graduates in determining the need for possible modifications. Method The article describes the results of a survey of 240 CSD PhD graduates and their perceptions of the challenges and facilitators to completing a PhD degree; the quality of their preparation in research, teaching, and job readiness; and ways to improve PhD education. Results Two primary themes emerged from the data highlighting the need for “matchmaking.” The first time point of needed matchmaking is prior to entry among students, mentors, and expectations as well as between aspects of the program that can lead to students' success and graduation. The second important matchmaking need is between the actual PhD preparation and the realities of the graduates' career expectations, and those placed on graduates by their employers. Conclusions Within both themes, graduate's perspectives and suggestions to help guide future doctoral preparation are highlighted. The graduates' recommendations could be used by CSD PhD program faculty to enhance the quality of their program and the likelihood of student success and completion.
