    Abstract Positron emission tomography (PET) using the glucose analog 18-F-fluoro-2-deoxy-D-glucose (FDG) is commonly obtained to stage patients with cancer. Benign lesions can be a source of false-positive PET examinations, leading to incorrect staging and treatment of tumors. Computed tomography can aid in distinguishing between certain benign and malignant lesions. The authors report a case of a pancreatic lipoma producing a false-positive PET examination.

    Abstract Although medical literature and differential diagnoses discussions tend to be organ specific, systemic diseases more commonly manifest with multi-organ involvement. Detection of dual organ involvement combined with clinical history narrows the differential to provide a more specific diagnosis. Two organs closely linked are the liver and the spleen. Many processes affect both of these organs through their common denominator, the reticuloendothelial system (RES). This pictorial essay reviews the wide spectrum of benign and malignant pathologies to be considered when computed tomography (CT) demonstrates concurrent focal disease in the liver and spleen.

    Abstract Primary evaluation of congenital cardiac abnormalities traditionally relies upon echocardiography and conventional angiography, both of which have potential limitations. Echocardiography is an operator dependant study, limited by a small window and patient movement. Conventional angiography is an invasive procedure with an inherent risk of catheter complication such as vessel damage, bleeding, stroke and infection. During angiography, overlapping of the pulmonary and systemic circulation often provides a confusing picture given complex anatomy. Another limiting factor of particular significance in young children is radiation dose and contrast administration during catherization procedures. Three-dimensional MDCT provides an alternative to alleviate these pitfalls of traditional cardiac diagnostic studies. Development of multi-detector computed tomography (MDCT) and 3D software provides new methods for non-invasive visualization and evaluation of congenital cardiac abnormalities. The multiplanar, volumetric functions allow faster and more complete computed tomography diagnosis and better understanding of clinical relevance of complex cardiac anatomy. In addition, 3D imaging is particularly useful for preoperative planning and postoperative outcomes. This essay provides case studies to illustrate the usefulness of MDCT/3D CT for evaluation of complex congenital heart disease.

    Abstract Indications for and experience with placement of endovascular stent-grafts in the thoracic aorta are still evolving. Common pathologic conditions of the thoracic aorta that are amenable to stent placement include penetrating ulcers, aortic dissection, aortic aneurysms, aortic rupture, and congenital abnormalities. Advances in multidetector computed tomography (CT) permit high-quality two-dimensional multiplanar reformation and three-dimensional rendering, which are essential for comprehensive assessment of the thoracic aorta. The ability of multidetector CT to allow detailed evaluation in any plane or perspective enables detection of thoracic aortic disease and assessment of its relationship to normal vessels. Potential complications of endovascular stent placement include endoleaks, stent migration, pseudoaneurysms, dissection, aortic perforation, kinking, thrombosis, and coverage of vital branch vessels. It is important for the radiologist to not only detect pathologic conditions of the thoracic aorta but also to provide the referring clinician with the necessary pre- and postprocedure information to determine appropriate clinical care.

    Abstract This study tests the hypotheses that insurance status, race and ethnicity, and neighborhood characteristics are associated with hospital admission and severe health outcomes (Intensive Care Unit [ICU] admission and oxygen assistance) for youth and young adults who present to the emergency department (ED) with COVID-19 in a single, academic health system in Illinois, Rush University System for Health (RUSH). Demographic and clinical data from the electronic health record were collected for all 13- to 24-y-old patients seen at RUSH who tested positive for COVID-19 between March 2020 and 2021. Individual-level and neighborhood characteristics were analyzed to determine their association with hospital admission and severe health outcomes through generalized estimating equations. As of March 2021, 1,057 patients were seen in the ED within RUSH in which non-Hispanic White (odds ratio [OR], 2.96; 95% CI, 1.61-5.46;

    Abstract Objective: The purpose of this study was to evaluate interpretative performance with different MDCT reconstruction parameters in adult patients with suspected appendicitis.
    Materials and methods: MDCT scans of 212 adult patients obtained in an emergency department with a 64-MDCT scanner were prospectively collected. Acquisition technique included 24 x 1.2 mm detector configuration and IV contrast administration with or without oral contrast administration. Data sets were reconstructed with three techniques: 5 x 5 mm, 3 x 3 mm, and 2 x 1 mm (section thickness x interval). Each of the 212 sets of images (grouped by reconstruction technique) was reviewed retrospectively using axial sections by two independent readers blinded to diagnosis. Medical record review was conducted to identify patients with appendicitis. Visualization of the appendix, confidence in visualization, confidence for presence or absence of specific CT findings, diagnostic accuracy, and diagnostic confidence were compared across reconstruction techniques. Data were analyzed with simple and ordinal logistic regression with adjustment for multiple observations derived from each patient and for reader differences.
    Results: Progressively thinner reconstruction section thickness was associated with a significant increase in the rate of visualization of the appendix (p < 0.001 for 5 x 5 vs 3 x 3; p = 0.03 for 3 x 3 vs 2 x 1), visualization confidence (p < 0.001 for 5 x 5 vs 3 x 3 and 3 x 3 vs 2 x 1), and confidence for presence or absence of findings. Seventeen subjects (8%) had appendicitis. Correctness of diagnosis was not significantly associated with reconstruction method. However, for correctly diagnosed cases interpreted as normal, impression confidence increased with progressively thinner section thickness (p < 0.001 for 5 x 5 vs 3 x 3 and 3 x 3 vs 2 x 1).
    Conclusion: In this investigation of contrast-enhanced MDCT of the appendix, visual ization of the appendix and confidence in interpretation of axial images progressively improved with use of thinner reconstruction sections.

    Abstract Objectives: Parental pediatric vaccine decisions are influenced by parents' health provider networks. Complementary and alternative medical providers may be key influences in the networks of those parents who do not vaccinate their children.
    Methods: From March to July 2013, we conducted semi-structured interviews of Oregon complementary and alternative medical providers (
    Results: This article identifies the range and type of immunological beliefs of complementary and alternative medical providers concerning pediatric vaccine recommendations. From repeated readings of the data, we identified three areas of alternative immunological beliefs among complementary and alternative medical providers (i.e. "natural is best," "innate intelligence," and "the fragile immune system"). In addition, complementary and alternative medical providers who embraced mainstream medicine were likely to be vaccine accepters and to mention vaccines as a positive health measure to their patients-these themes were "vaccines prevent illness" and "herd immunity."
    Conclusion: Complementary and alternative medical providers influence their patients' vaccination decisions, particularly urging caution or complete vaccine avoidance, and may be a major influence in states like Oregon with high non-medical exemption rates. Complementary and alternative medical providers come to their anti-vaccine positions largely through post-graduation continuing education courses and seminars. In Oregon, such courses are unregulated and not vetted.

    Series title Routledge interpretive marketing research
    Abstract "Taste is a core concept for the social sciences and an orienting notion in everyday practice. It is of equal relevance to academics and laypeople alike. Theorizations of taste are frequently multi- disciplinary, bringing an opportunity to cross-fertilize ideas and concepts. At the same time, a reader, challenged by the diverse body and dispersed nature of theories on taste, needs guidance navigating the literature and framing areas of interest. Until now, those interested in an academic perspective on the concept have had to traverse a wide range of literature. This is the first book that assembles a range of writings on taste from across disciplines to provide the reader with a sense of the emerging and expanding boundaries of this field of study. Taste, Consumption and Markets offers a comprehensive and up-to-date review of taste, with an emphasis on how taste shapes boundaries, subcultures, and global culture, complemented by an introduction that provides a scaffold for the reader and a concluding section that reflects on the past, present, and future of research on taste. It shows the latest state of knowledge on the topic and will be of interest to students at an advanced level, academics, and reflective practitioners. It addresses the topics with regard to the sociology of taste and consumption and will be of interest to researchers, academics, and students in the fields of consumer studies, consumption ethics, sociological perspectives on consumption, and cultural studies"--

    Abstract: ... contaminated pasture in late winter/early spring (February/March).: Conclusion: The study illustrated ...

    Abstract Background: The Barber's Pole worm, Haemonchus contortus is of major concern to sheep producers, particularly in the southern hemisphere. This nematode is also commonly found in many sheep flocks in Northern hemisphere countries but is generally not associated with acute clinical pathology. As with other nematode species, the pattern of disease is changing in the United Kingdom. Changes in management practices, climate, anthelmintic resistance prevalence and parasite adaptation are possible factors thought to be responsible for this.
    Methods: In the present study, a combination of traditional applied parasitological and molecular species identification techniques were used to assess the capability of H. contortus infective larvae to over-winter on pasture and infect lambs in early spring.
    Results: Adult and inhibited H. contortus worms were identified in previously worm-free tracer lambs that had grazed contaminated pasture in late winter/early spring (February/March).
    Conclusion: The study illustrated the benefit of using classical applied parasitology techniques in conjunction with molecular species identification methods to explore the epidemiology of gastro-intestinal nematodes of livestock. This study also demonstrated that larvae were able to survive over-winter, albeit in small numbers, and potentially contaminate pastures earlier than previously considered in northern regions of the UK.

    Abstract Objectives: Parental pediatric vaccine decisions are influenced by parents’ health provider networks. Complementary and alternative medical providers may be key influences in the networks of those parents who do not vaccinate their children. Methods: From March to July 2013, we conducted semi-structured interviews of Oregon complementary and alternative medical providers ( N = 36) in five disciplines likely to treat parents or children, or both, and whose practitioners are known to express opinions about vaccines and vaccination. We interviewed them concerning their immunology beliefs, vaccine positions, and what these providers recommend to their patients concerning vaccines. We conducted face-to-face interviews and analyzed the interview data using thematic analysis methodology. Results: This article identifies the range and type of immunological beliefs of complementary and alternative medical providers concerning pediatric vaccine recommendations. From repeated readings of the data, we identified three areas of alternative immunological beliefs among complementary and alternative medical providers (i.e. “natural is best,” “innate intelligence,” and “the fragile immune system”). In addition, complementary and alternative medical providers who embraced mainstream medicine were likely to be vaccine accepters and to mention vaccines as a positive health measure to their patients—these themes were “vaccines prevent illness” and “herd immunity.” Conclusion: Complementary and alternative medical providers influence their patients’ vaccination decisions, particularly urging caution or complete vaccine avoidance, and may be a major influence in states like Oregon with high non-medical exemption rates. Complementary and alternative medical providers come to their anti-vaccine positions largely through post-graduation continuing education courses and seminars. In Oregon, such courses are unregulated and not vetted.
