Determination of 27 Elements in Animal Feed by Inductively Coupled Plasma-Mass Spectrometry.

A method was developed to determine 27 elements (aluminum, arsenic, boron, cadmium, calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese, mercury, molybdenum, nickel, phosphorus, potassium, selenium, sodium, sulfur, vanadium, zinc, antimony, uranium, beryllium, thallium, and thorium) in animal feeds and pet foods using closed vessel microwave digestion and inductively coupled plasma-mass spectrometry. These elements can adversely affect animal health when amounts become excessive or deficient in food. For potentially toxic elements, the target LOQ was determined to be 1/10 the lowest maximum tolerable level (MTL) for the most sensitive animal species. For nutritionally essential elements, the target LOQ was determined to be 1/10 the concentration that would be considered deficient in feed if that level is lower than 1/10 the lowest MTL. The targeted high end of the quantitation range was selected as twice the highest MTL. A single-laboratory validation (SLV) was performed to determine the accuracy and precision of the method, and the results were evaluated with respect to predetermined performance characteristics. The test materials used in the SLV included two National Institute of Standards and Technology certified reference materials, two Association of American Feed Control Officials (AAFCO) check samples, and one in-house previously analyzed feed sample. The concentrations of each element determined were the result of spiked analyte, incurred analyte, or a combination of spiked and incurred analyte. All samples were analyzed seven times on different days at 2 × LOQ and at the midrange concentration. For most data, the results of the SLV met or exceeded the criteria for accuracy and repeatability. For accuracy, K at the midrange level had a mean recovery of 95%, which is just below the low preferred accuracy threshold of 97%. For repeatability, all the 2 × LOQ CVr values were below the preferred values. Be, Cr, Ni, Na, Mn, and S all had midrange CVr values exceeding the preferred values. Be had the highest midrange CVr value of 9.93. Eight AAFCO check samples were also analyzed to determine the method's accuracy and repeatability for elements at the manufacturer's claimed levels. For accuracy, all results had z-scores <1.5. For repeatability, three CVr values from two AAFCO check samples were greater than the preferred limits.

Abstract WP168: Cerebrovascular Reactivity Predicts Surgical Decisions in Moyamoya Patients

Introduction: Moyamoya disease (MMD) is characterized by chronic occlusion of the distal intracranial internal carotid arteries and can be treated by revascularization surgery. At present, surgical decisions are primarily based on symptomatology and imaging studies using DSA and SPECT, which are are costly, invasive, time consuming and qualitative. Here we applied a novel iVas-MRI technique that provides quantitative assessment of multiple hemodynamic parameters in a 9-minute scan in MMD patients, and evaluated the ability of iVas parametric maps to predict surgical decisions in such patients. Methods: Sixteen MMD patients were scanned on 3T MRI. Each patient had at least one hemisphere pending decision regarding surgery at the time of MRI. During iVas-MRI, a concomitant CO2/O2 breathing challenge was performed while BOLD images were continuously collected. BOLD images and end-tidal (Et) CO2 and O2 traces were used to calculate maps of cerebrovascular reactivity (CVR, based on BOLD signal change to EtCO2 change), cerebral blood volume (CBV, based on BOLD signal change to EtO2 change), and bolus arrival time (BAT, based on the time lag between EtCO2/O2 and BOLD signal). Parametric values from the ICA perfusion territory were compared between two groups, surgical and medical, with decision made by the treating neurosurgeons blinded to research data. The area-under-the-ROC-curve (AUC) was calculated to evaluate the performance of the MRI indices in predicting surgical decisions. Results: Out of the 23 hemispheres under consideration, 9 were diagnosed as surgical and 14 considered medical. CVR, CO2-BAT and O2-BAT values showed significant differences between the two groups (p=0.0002, 0.005 and 0.001, respectively), while CBV values showed no difference (p=0.45). Brain hemispheres that required revascularization surgeries had lower CVR and longer BAT, compared to medically-managed hemispheres. ROC analyses revealed an AUC of 0.89, 0.84 and 0.95 for CVR, O2-BAT, and CO2-BAT respectively. Conclusion: Our results showed that CVR and BAT had a great accuracy in predicting surgical decisions. Therefore, iVas-MRI may be a cost-effective and reliable method to select between medical and surgical treatments for MMD patients.

Magnetic resonance imaging for assessment of cerebrovascular reactivity and its relationship to cognition: a systematic review

BackgroundCerebrovascular reactivity (CVR) refers to the responsiveness of cerebral vasculature to vasoactive stimuli. CVR is an indicator of brain health and can be assessed using vasodilatory techniques and magnetic resonance imaging (MRI). Using such approaches, some researchers have explored the relationship between CVR and cognition; here we systematically review this work.ResultsWe extracted information pertaining to: (1) study location and design, participant characteristics, sample sizes, (2) design of vascular challenge, end-tidal CO2 (etCO2) concentrations (if applicable), (3) MRI protocol, (4) cognitive assessment, (5) CVR values, and outcomes of statistical analyses with cognitive tests. Five studies assessed participants with cognitive impairment compared to controls, one studied patients with multiple sclerosis with or without cognitive impairment compared to controls, one examined patients with moyamoya disease with or without cognitive impairment, two investigated patients with Type 2 diabetes mellitus (T2DM), and one was a cross-sectional study with younger and older healthy adults. Cognition was typically probed using the MMSE and tests of executive function, while a number of vasodilatory techniques were employed.ConclusionCVR was associated with cognition in six of ten studies, but heterogeneity of study samples, designs and vasodilatory methods may have a role in the inconsistent findings. We make recommendations for future research that includes use of a multi-domain cognitive assessment and standardised hypercapnic challenge with MRI.

Comparison of congenital pulmonary airway malformation volume ratios calculated by ultrasound and magnetic resonance imaging

Objective: To compare congenital pulmonary airway malformation (CPAM) volume to head circumference ratios (CVRs) determined by different imaging modalities and calculation techniques.Methods: Fetal thoracic lesion images by ultrasound (US) and magnetic resonance imaging (MRI) were retrospectively reviewed and the CVRs were calculated. The CVRUS was determined by the standard method. The CVRMRI was calculated from T2-weighted sequences (HASTE/SSH-TSE) in two ways, dimensional measurements analogous to US technique (MRI-D) and by using a MRI-software calculated volume (MRI-V). CVR values between methods were compared using Wilcoxon matched-pairs signed-rank testing, Bland–Altman analyses, and Spearman correlations.Results: Appropriate images were available to compare CVRUS to CVRMRI-D for 20 patients and CVRUS to CVRMRI-V for 18 patients. There were no significant differences in CVR values between modalities. By Bland–Altman analyses, the CVR measurements were largely within the limits of agreement: 18 of 20 for CVRMRI-D and 17 of 18 for CVRMRI-V, with a slight bias towards larger measurements by MRI.Conclusions: Though values varied between modalities for individual patients, there was no systematic difference in CVRs determined by US or MRI. Fetal prognostic category for CPAMs did not change based on MRI in any patient in this series.

Integrative STEM education is an engineering design-based learning approach that purposefully integrates the content and process of STEM disciplines and can extend its concept to integration with other school subjects. This study was part of fundamental research to develop an integrative STEM education program based on the science inquiry process. The specific objectives of this study were to review relevant literature related to STEM education, analyze the key elements and value of STEM education, develop an integrative STEM education model based on the science inquiry process, and suggest an exemplary program. This study conducted a systematic literature review to confirm key elements for integrative STEM education and finally constructed the integrative STEM education model through analyzing key inquiry processes extracted from prior studies. This model turned out to be valid because the average CVR value obtained from expert group was 0.78. The integrative STEM education model based on the science inquiry process consisted of two perspectives of the content and inquiry process. The content can contain science, technology, engineering, and liberal arts/artistic topics that students can learn in a real world context/problem. Also, the inquiry process is a problem-solving process that contains design and construction and is based on the science inquiry. It could integrate the technological/engineering problem solving process and/or mathematical problem solving process. Students can improve their interest in STEM subjects by analyzing real world problems, designing possible solutions, and implementing the best design as well as acquire knowledge, inquiry methods, and skills systematically. In addition, the developed programs could be utilized in schools to enhance students' understanding of STEM disciplines and interest in mathematics and science. The programs could be used as a basis for fostering convergence literacy and cultivating integrated and design-based problem-solving ability.

Evaluating the reliability and validity of phonetic information test in normal 3-6 year-old children of Isfahan city

Introduction: Speech sound disorder is one of the most prevalent developmental communication disorders affecting approximately 8.7 percent of school-age children. Speech sound disorders require precise diagnosis and assessment which can be reached via formal and informal evaluations. Speech-language pathologists generally use the Phonetic Information Test to detect the disordered pronunciation of sounds. Unfortunately, the reliability and validity of this test have not been determined yet. The purpose of the present study was to test the reliability and validity of Phonetic Information Test as the first stage of its standardizing. Materials and Methods: At the first phase of this descriptive and methodological study, the content validity of the test was determined through quantifying the comments of 20 speech-language pathologists. Then, 150 children with the age range of 3 to 6 years were evaluated using the test and their scores were statistically analyzed by the two methods of Kuder-Richardson 20 and test-retest correlation to determine the reliability of the test. Data analysis was performedviaSPSS13. Results: The CVR value for words was higher than 42percent except for /kaeʧae/. Kuder-Richardson20 and correlation coefficient results in the three age groups demonstrated that the test has appropriate reliability. Conclusion: The results of this study showed that the phonetic test meets validity and reliability requirements and, therefore, is sufficiently accurate to be used in the diagnosis and assessment of articulation impairments.
