Foodborne disease control: a transnational challenge.

In the globalized political economy of the late 20th century, increasing social, political, and economic interdependence is occurring as a result of the rapid movement of people, images, values, and financial transactions across national borders. Another consequence of the increase in transnational trade, travel, and migration is the greater risk of cross-border transmission of infectious diseases. As the world becomes more interconnected, diseases spread more rapidly and effectively. With more than one million people crossing international borders every day, and with the globalization of food production, manufacturing, and marketing, the risk of infectious disease transmission is greater. Economic globalization has also increased the need for governmental budget austerity, and consequent national preparedness has been eroded. The emergence of new infectious diseases, as well as the reemergence of old ones, thus represents a crucial transnational policy issue. These problems cannot be resolved by national governments alone; they require international cooperation. This article analyzes the role of foodborne disease surveillance programs, nationally and internationally, in the control of foodborne diseases

Focal CA3 hippocampal subfield atrophy following LGI1 VGKC-complex antibody limbic encephalitis

Magnetic resonance imaging has linked chronic voltage-gated potassium channel (VGKC) complex antibody-mediated limbic encephalitis with generalized hippocampal atrophy. However, autoantibodies bind to specific rodent hippocampal subfields. Here, human hippocampal subfield (subiculum, cornu ammonis 1-3, and dentate gyrus) targets of immunomodulation-treated LGI1 VGKC-complex antibody-mediated limbic encephalitis were investigated using in vivo ultra-high resolution (0.39 x 0.39 x 1.0 mm³) 7.0T magnetic resonance imaging [n = 18 patients, 17 patients (94%) positive for LGI1 antibody and one patient negative for LGI1/CASPR2 but positive for VGKC-complex antibodies, mean age: 64.0 ± 2.55 years, median 4 years post-limbic encephalitis onset; n = 18 controls]. First, hippocampal subfield quantitative morphometry indicated significant volume loss confined to bilateral CA3 [F(1,34) = 16.87, P 3 months from symptom onset) were associated with CA3 atrophy. Third, whole-brain voxel-by-voxel morphometry revealed no significant grey matter loss. Fourth, CA3 subfield atrophy was associated with severe episodic but not semantic amnesia for postmorbid autobiographical events that was predicted by variability in CA3 volume. The results raise important questions about the links with histopathology, the impact of the observed focal atrophy on other CA3-mediated reconstructive and episodic mechanisms, and the role of potential antibody-mediated pathogenicity as part of the pathophysiology cascade in humans

In what ways does the mandatory nature of Victoria's municipal public health planning framework impact on the planning process and outcomes?

BACKGROUND: Systems for planning are a critical component of the infrastructure for public health. Both in Australia and internationally there is growing interest in how planning processes might best be strengthened to improve health outcomes for communities. In Australia the delivery of public health varies across states, and mandated municipal public health planning is being introduced or considered in a number of jurisdictions. In 1988 the Victorian State government enacted legislation that made it mandatory for each local government to produce a Municipal Public Health Plan, offering us a 20-year experience to consider. RESULTS: In-depth interviews were undertaken with those involved in public health planning at the local government level, as part of a larger study on local public health infrastructure and capacity. From these interviews four significant themes emerge. Firstly, there is general agreement that the Victorian framework of mandatory public health planning has led to improvements in systems for planning. However, there is some debate about the degree of that improvement. Secondly, there is considerable variation in the way in which councils approach planning and the priority they attach to the process. Thirdly, there is concern that the focus is on producing a plan rather than on implementing the plan. Finally, some tension over priorities is evident. Those responsible for developing Municipal Public Health Plans express frustration over the difficulty of having issues they believe are important addressed through the MPHP process. CONCLUSION: There are criticisms of Victoria's system for public health planning at the local government level. Some of these issues may be specific to the arrangement in Victoria, others are problems encountered in public health planning generally. In Victoria where the delivery structure for public health is diverse, a system of mandatory planning has created a minimum standard. The implementation of the framework was slow and factors in the broader political environment had a significant impact. Work done in recent years to support the process appears to have led to improvements. There are lessons for other states as they embark upon mandated public health plans

Body Fluid Cytokine Levels in Mild Cognitive Impairment and Alzheimer’s Disease: a Comparative Overview

This article gives a comprehensive overview of cytokine and other inflammation associated protein levels in plasma, serum and cerebrospinal fluid (CSF) of patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). We reviewed 118 research articles published between 1989 and 2013 to compare the reported levels of 66 cytokines and other proteins related to regulation and signaling in inflammation in the blood or CSF obtained from MCI and AD patients. Several cytokines are evidently regulated in (neuro-) inflammatory processes associated with neurodegenerative disorders. Others do not display changes in the blood or CSF during disease progression. However, many reports on cytokine levels in MCI or AD are controversial or inconclusive, particularly those which provide data on frequently investigated cytokines like tumor necrosis factor alpha (TNF-α) or interleukin-6 (IL-6). The levels of several cytokines are possible indicators of neuroinflammation in AD. Some of them might increase steadily during disease progression or temporarily at the time of MCI to AD conversion. Furthermore, elevated body fluid cytokine levels may correlate with an increased risk of conversion from MCI to AD. Yet, research results are conflicting. To overcome interindividual variances and to obtain a more definite description of cytokine regulation and function in neurodegeneration, a high degree of methodical standardization and patients collective characterization, together with longitudinal sampling over years is essential
