    Osteopathic manipulative medicine texts and educators advocate a range of approaches for physical assessment and treatment, but little is known about their use by osteopathic physicians in the United States. A web-based survey using a 5-point Likert scale was developed and e-mailed to 777 practicing osteopathic physician members of the American Academy of Osteopathy. Responses in the "frequently" and "always" categories were combined for reporting purposes. Friedman tests were used to analyze the reported usage of each item. The effect of gender was analyzed using Mann-Whitney tests. Respondents reported the use of a broad range of assessment and treatment approaches. Results suggest a higher use of myofascial release and cranial technique and lower use of high-velocity techniques in this group of physicians compared to previous studies

    Item-specific proactive interference in olfactory working memory.

    Get PDF
    We examine item-specific olfactory proactive interference (PI) effects and undertake comparisons with verbal and non-verbal visual stimuli. Using a sequential recent-probes task, we show no evidence for PI with hard-to-name odours (Experiment 1). However, verbalisable odours do exhibit PI effects (Experiment 2). These findings occur despite above chance performance and similar serial position functions across both tasks. Experiments 3 and 4 apply words and faces, respectively, to our modified procedure, and show that methodological differences cannot explain the null finding in Experiment 1. The extent to which odours exhibit analogous PI effects to that of other modalities is, we argue, contingent on the characteristics of the odours employed

    Implementing One Health in Australia: A modified Delphi survey and analysis of expert perspectives

    Get PDF
    One Health (OH) is an interdisciplinary approach aiming to achieve optimal health for humans, animals and their environments. Case reports and systematic reviews of success are emerging; however, discussion of barriers and enablers of cross-sectoral collaboration are rare. A four-phase mixed-method Delphi survey of Australian human and animal health practitioners and policymakers (n = 52) explored areas of consensus and disagreement over: (1) the operational definition of OH; (2) potential for cross-sectoral collaboration; and (3) key priorities for shaping the development of an OH response to significantly elevated zoonotic disease risk. Participants agreed OH is essential for effective infectious disease prevention and control, and on key priorities for outbreak responses, but disagreed over definitions and the relative priority of animal health and welfare and economic considerations. Strong support emerged among Australian experts for an OH approach. There was also recognition of the need to ensure cross-sectoral differences are addressed

    Some Like It Hot: Linking Diffuse X-ray Luminosity, Baryonic Mass, and Star Formation Rate in Compact Groups of Galaxies

    We present an analysis of the diffuse X-ray emission in 19 compact groups of galaxies (CGs) observed with Chandra. The hottest, most X-ray luminous CGs agree well with the galaxy cluster X-ray scaling relations in LXTL_X-T and LXσL_X-\sigma, even in CGs where the hot gas is associated with only the brightest galaxy. Using Spitzer photometry, we compute stellar masses and classify HCGs 19, 22, 40, and 42 and RSCGs 32, 44, and 86 as fossil groups using a new definition for fossil systems that includes a broader range of masses. We find that CGs with total stellar and HI masses 1011.3\gtrsim10^{11.3} M_\odot are often X-ray luminous, while lower-mass CGs only sometimes exhibit faint, localized X-ray emission. Additionally, we compare the diffuse X-ray luminosity against both the total UV and 24 μ\mum star formation rates of each CG and optical colors of the most massive galaxy in each of the CGs. The most X-ray luminous CGs have the lowest star formation rates, likely because there is no cold gas available for star formation, either because the majority of the baryons in these CGs are in stars or the X-ray halo, or due to gas stripping from the galaxies in CGs with hot halos. Finally, the optical colors that trace recent star formation histories of the most massive group galaxies do not correlate with the X-ray luminosities of the CGs, indicating that perhaps the current state of the X-ray halos is independent of the recent history of stellar mass assembly in the most massive galaxies.Comment: 20 pages, 7 figures, accepted for publication in Ap

    Examining the Role of Environment in a Comprehensive Sample of Compact Groups

    (Abridged) Compact groups, with their high number densities, small velocity dispersions, and an interstellar medium that has not been fully processed, provide a local analog to conditions of galaxy interactions in the earlier universe. The frequent and prolonged gravitational encounters that occur in compact groups affect the evolution of the constituent galaxies in a myriad of ways, for example gas processing and star formation. Recently, a statistically significant "gap" has been discovered mid-infrared IRAC colorspace of compact group galaxies. This gap is not seen in field samples and is a new example of how the compact group environment may affect the evolution of member galaxies. In order to investigate the origin and nature of this gap, we have compiled a sample of 49 compact groups. We find that a statistically significant deficit of galaxies in this gap region of IRAC colorspace is persistant in this sample, lending support to the hypothesis that the compact group environment inhibits moderate SSFRs. We note a curvature in the colorspace distribution, which is fully consistent with increasing dust temperature as the activity in a galaxy increases. This full sample of 49 compact groups allows us to subdivide the data according to physical properties of the groups. An analysis of these subsamples indicates that neither projected physical diameter nor density show a trend in colorspace within the values represented by this sample. We hypothesize that the apparent lack of a trend is due to the relatively small range of properties in this sample. Thus, the relative influence of stochastic effects becomes dominant. We analyze spectral energy distributions of member galaxies as a function of their location in colorspace and find that galaxies in different regions of MIR colorspace contain dust with varying temperatures and/or PAH emission.Comment: 24 pages, 13 figures.

    The effect of osteopathic manipulative treatment on length of stay in posterolateral postthoracotomy patients: A retrospective case note study

    Get PDF
    Objective This study retrospectively evaluated the effect of OMT on length of stay (LOS) in hospitalized posterolateral postthoracotomy patients. Methods Inpatient medical records of patients who received posterolateral thoracotomies with lung resection between 1998 and 2011 were reviewed for demographic data, LOS, thoracotomy surgery data, consultation data excluding osteopathic manipulative medicine, discharge data, and osteopathic manipulative medicine consultation data. Results Thirty-eight patients received posterolateral thoracotomies with lung resection; 23 patients received OMT and 15 did not. The mean (standard deviation) LOS was 11.0 (6.8) days (range, 5–29 days) for those who received OMT and 10.4 (5.5) days (range, 3–22 days) for those who did not (P = .90). Five patients developed postoperative ileus, and all had received OMT. Patients receiving 2 surgical procedures had a longer LOS than those receiving 1 surgical procedure (P = .002). Having a decortication performed during the thoracotomy increased LOS by a mean of 6.4 days (P = .005). Patients admitted directly to the intensive care unit were more likely to receive OMT than those who were not (P = .03). Conclusion While there was no difference in LOS, severity of illness was different between patients who received OMT and those who did not. Patients who developed postoperative ileus and most of those admitted directly to the intensive care unit received OMT, suggesting that severity of illness was greater for those who received OMT. Future studies should include a higher subject number in order to stratify for illness severity and also assess the effect of OMT on postoperative pain

    The Infrared Properties of Hickson Compact Groups

    Compact groups of galaxies provide a unique environment to study the mechanisms by which star formation occurs amid continuous gravitational encounters. We present 2MASS (JHK), Spitzer IRAC (3.5-8 micron) and MIPS (24 micron) observations of a sample of twelve Hickson Compact Groups (HCGs 2, 7, 16, 19, 22, 31, 42, 48, 59, 61, 62, and 90) that includes a total of 45 galaxies. The near-infrared colors of the sample galaxies are largely consistent with being dominated by slightly reddened normal stellar populations. Galaxies that have the most significant PAH and/or hot dust emission (as inferred from excess 8 micron flux) also tend to have larger amounts of extinction and/or K-band excess and stronger 24 micron emission, all of which suggest ongoing star formation activity. We separate the twelve HCGs in our sample into three types based on the ratio of the group HI mass to dynamical mass. We find evidence that galaxies in the most gas-rich groups tend to be the most actively star forming. Galaxies in the most gas-poor groups tend to be tightly clustered around a narrow range in colors consistent with the integrated light from a normal stellar population. We interpret these trends as indicating that galaxies in gas-rich groups experience star formation and/or nuclear actively until their neutral gas consumed, stripped, or ionized. The galaxies in this sample exhibit a ``gap'' between gas-rich and gas-poor groups in infrared color space that is sparsely populated and not seen in the Spitzer First Look Survey sample. This gap may suggest a rapid evolution of galaxy properties in response to dynamical effects. These results suggest that the global properties of the groups and the local properties of the galaxies are connected.Comment: 34 pages, 26 figures, accepted for publication in AJ, higher quality images available in publicatio
