Discourses of Diabetes Management in Patient-Physician Interactions
Discussions of diabetes management are challenging for patients and physicians during treatment plan appointments—in large part because “diabetes management” has multiple, competing meanings. Our goal in this study was to examine talk between patients and physicians over multiple visits to: (1) determine the multiple meanings of diabetes management, and (2) determine the specific ways these meanings compete with each other. To accomplish this goal, we gathered data at a family medicine residency clinic in the Midwestern United States, video-recording the interactions of six different patient-physician dyads over multiple visits. Next, we performed in-depth analyses of these interactions using Baxter’s (2011) Relational Dialectics Theory 2.0, which focuses on discourses occurring within interpersonal interactions, rather than on the individuals within interpersonal interactions. Our results reveal meanings associated with two dominant oppositional discourses comprising the meaning of diabetes management: high self-efficacy and low self-efficacy. Additionally, we found that—during conversations between patients and physicians—the central discourse of high self-efficacy competed with the less-central discourse of low self-efficacy. Our results also reveal that both patients and physicians used both discourses. Finally, our results revealed that at times, both patients and physicians mixed these discourses, creating a new “hybrid” meaning for diabetes management: Moderation. Understanding these discourses and how they compete can help physicians focus on the cultural discourses that shape their own and patients’ views of diabetes management and realize the transformational possibilities that can occur in treatment plan discussions through a more moderate discourse
Pine Needle Abortion in Cattle: A Progress Report
Cow and calf loss due to pine needle abortion (PNA) in cattle grazing foothill ranges having stands of ponderosa pine (Pinus ponderosa) continues to cause managerial, as well as economic problems, for many ranchers in South Dakota, Colorado, Idaho and California as well as many areas in Canada
Viperin is an important host restriction factor in control of Zika virus infection
Published online 30 June 2017Zika virus (ZIKV) infection has emerged as a global health threat and infection of pregnant women causes intrauterine growth restriction, spontaneous abortion and microcephaly in newborns. Here we show using biologically relevant cells of neural and placental origin that following ZIKV infection, there is attenuation of the cellular innate response characterised by reduced expression of IFN-β and associated interferon stimulated genes (ISGs). One such ISG is viperin that has well documented antiviral activity against a wide range of viruses. Expression of viperin in cultured cells resulted in significant impairment of ZIKV replication, while MEFs derived from CRISPR/Cas9 derived viperin-/- mice replicated ZIKV to higher titers compared to their WT counterparts. These results suggest that ZIKV can attenuate ISG expression to avoid the cellular antiviral innate response, thus allowing the virus to replicate unchecked. Moreover, we have identified that the ISG viperin has significant anti-ZIKV activity. Further understanding of how ZIKV perturbs the ISG response and the molecular mechanisms utilised by viperin to suppress ZIKV replication will aid in our understanding of ZIKV biology, pathogenesis and possible design of novel antiviral strategies.Kylie H.

Which executive functioning deficits are associated with AD/HD, ODD/CD and comorbid AD/HD+ODD/CD?
Item does not contain fulltextThis study investigated (1) whether attention deficit/hyperactivity disorder (AD/HD) is associated with executive functioning (EF) deficits while controlling for oppositional defiant disorder/conduct disorder (ODD/CD), (2) whether ODD/CD is associated with EF deficits while controlling for AD/HD, and (3)~whether a combination of AD/HD and ODD/CD is associated with EF deficits (and the possibility that there is no association between EF deficits and AD/HD or ODD/CD in isolation). Subjects were 99~children ages 6–12 years. Three putative domains of EF were investigated using well-validated tests: verbal fluency, working memory, and planning. Independent of ODD/CD, AD/HD was associated with deficits in planning and working memory, but not in verbal fluency. Only teacher rated AD/HD, but not parent rated AD/HD, significantly contributed to the prediction of EF task performance. No EF deficits were associated with ODD/CD. The presence of comorbid AD/HD accounts for the EF deficits in children with comorbid AD/HD+ODD/CD. These results suggest that EF deficits are unique to AD/HD and support the model proposed by R. A. Barkley (1997).17 p
Tear secretion dysfunction among women workers engaged in light-on tests in the TFT-LCD industry
BACKGROUND: The TFT-LCD (thin film transistor liquid crystal display) industry is rapidly growing in Taiwan and many other countries. A large number of workers, mainly women, are employed in the light-on test process to detect the defects of products. At the light-on test workstation, the operator is generally exposed to low humidity (in the clean room environment), flashing light, and low ambient illumination for long working hours. Many workers complained about eye discomfort, and therefore we conducted a study to evaluate the tear secretion function of light-on test workers of a TFT-LCD company. METHODS: We recruited workers engaged in light-on tests in the company during their periodical health examination. In addition to a questionnaire survey of demographic characteristics and ophthalmic symptoms, we evaluated the tear secretion function of both eyes of each participant using the Schirmer's lacrimal basal secretion test with anaesthesia. A participant with one or both eyes yielding abnormal test results was defined as a case of tear secretion dysfunction. RESULTS: During the study period, a total of 371 light-on test workers received the health examination at the clinic of the park, and 52 of them were excluded due to having ophthalmic diseases and other systemic diseases that may affect ophthalmic function. All the remaining 319 qualified workers agreed to participate in this study, and they were all females working by 4-shift rotations. The average age was 24.2 years old (standard deviation [SD] = 3.8), and the average employment duration was 13.6 months (SD = 5.7). Among the 11 ophthalmic symptoms evaluated, eye dryness was the most prevalent (prevalence = 43.3%). In addition, the prevalence of tear secretion dysfunction in at least one eye was 40.1% (128 cases), and contact lens users had an odds ratio of 1.73 (95% confidence interval = 1.02–2.94) in comparison with non-contact lens users. Comparing the Schirmer's test results of those who also participated in the screening in the previous year, we found 40 of the 156 participants (17.2%) with normal test results in the previous year turned abnormal in 2001. In contrast, only 21 of the 76 participants (9.1%) with abnormal test results in the previous year turned normal, and the difference was statistically significant (p = 0.02 for McNemar's test). CONCLUSION: The prevalence of tear secretion dysfunction in woman workers engaged in light-on tests is high and increases with a one-year duration of employment. The use of contact lens may further increase the risk
Challenges in QCD matter physics - The Compressed Baryonic Matter experiment at FAIR
Substantial experimental and theoretical efforts worldwide are devoted to
explore the phase diagram of strongly interacting matter. At LHC and top RHIC
energies, QCD matter is studied at very high temperatures and nearly vanishing
net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was
created at experiments at RHIC and LHC. The transition from the QGP back to the
hadron gas is found to be a smooth cross over. For larger net-baryon densities
and lower temperatures, it is expected that the QCD phase diagram exhibits a
rich structure, such as a first-order phase transition between hadronic and
partonic matter which terminates in a critical point, or exotic phases like
quarkyonic matter. The discovery of these landmarks would be a breakthrough in
our understanding of the strong interaction and is therefore in the focus of
various high-energy heavy-ion research programs. The Compressed Baryonic Matter
(CBM) experiment at FAIR will play a unique role in the exploration of the QCD
phase diagram in the region of high net-baryon densities, because it is
designed to run at unprecedented interaction rates. High-rate operation is the
key prerequisite for high-precision measurements of multi-differential
observables and of rare diagnostic probes which are sensitive to the dense
phase of the nuclear fireball. The goal of the CBM experiment at SIS100
(sqrt(s_NN) = 2.7 - 4.9 GeV) is to discover fundamental properties of QCD
matter: the phase structure at large baryon-chemical potentials (mu_B > 500
MeV), effects of chiral symmetry, and the equation-of-state at high density as
it is expected to occur in the core of neutron stars. In this article, we
review the motivation for and the physics programme of CBM, including
activities before the start of data taking in 2022, in the context of the
worldwide efforts to explore high-density QCD matter.Comment: 15 pages, 11 figures. Published in European Physical Journal
Chris Brown’s Liberal Conservatism, the Process of Moral Learning and Global Institutional Transformations
In the normative theory of International Relations, the major debate has been between the state-centric view and cosmopolitanism. A quarter of century ago I attempted to deconstruct one round of this debate – between Chris Brown and Mark Hoffman – by showing that the debate is both utopian and has an other-negating character. With the help of epistemological discussions and an analysis of two “case studies”, I built a case for a contextualist and dialogical morality, grounded on the concept of judgement. Interestingly, Brown’s 2010 collection of essays is entitled Practical Judgement in International Political Theory. In this paper I first explore whether similar or analogical deconstruction would anymore be possible. Second, I discuss Brown’s ideas about global civil society, democracy and justice, particularly in light of world-historical developments since the early 1990s and in relation to the development of my own thinking on the topic. While Brown has tried to overcome the dichotomy between the state-centric view and cosmopolitanism, I examine whether the idea of universal ethico-political learning and its cosmopolitan implications might explain the divergence in our practical judgements. I conclude by arguing any area of activities in international relations and world society, from property and contract to nuclear safety and global warming, can be subject to normative debates and potentially democratic politics. Good normative arguments often involve designs for better institutions, but they must be realizable by virtue of being connected to real causal processes.Peer reviewe
