Brain Cancer Risk and Electromagnetic Fields (EMFs): Assessing the Geomagnetic Component

Cancer cluster studies in North Carolina identified several communities in which there existed an elevated risk of brain cancer. These findings prompted a series of case-control studies. The current article, which originated from the results of the 3rd of such studies, is focused on inclusion of the earth's own geomagnetic fields that interact with electromagnetic fields generated from distribution power lines. This article also contains an assessment of the contribution of confounding by residential (e.g., urban, rural) and case characteristics (e.g., age, race, gender). Newly diagnosed brain cancer cases were identified for a 4-county region of central North Carolina, which the authors chose on the basis of the results of earlier observations. A 3:1 matched series of cancer cases from the same hospitals in which the cases were diagnosed served as the comparison group. Extensive geographic information was collected and was based on an exact place of residence at the time of cancer diagnosis, thus providing several strategic geophysical elements for assessment. The model for this assessment was based on the effects of these two sources of electromagnetic fields for an ion cyclotron resonance mechanism of disease risk. The authors used logistic regression models that contained the predicted value for the parallel component of the earth's magnetic field; these models were somewhat erratic, and the elements were not merged productively into a single statistical model. Interpretation of these values was difficult; therefore, the modeled values for the model elements, at progressive distances from the nearest power-line segments, are provided. The results of this study demonstrate the merits of using large, population-based databases, as well as using rigorous Geographic Information System techniques, for the assessment of ecologic environmental risks. The results also suggest promise for exposure classification that is compatible with the theoretical biological mechanisms posited for electromagnetic fields.     

Universal Design and Assistive Technology in Communication and Information Technologies: Alternatives or Complements?

Universal design and assistive technology present advantages and disadvantages in accommodating the needs of people with disabilities. The best solution may be a combination of the two, using universal design wherever possible and commercially practical and using assistive technologies wherever it is necessary or provides sufficient additional advantage to the user. Three approaches are discussed for the individual who is unable to interact with their world: change the individual, provide them with tools they can use, or change the environment. Examples of each are illustrated using personal workstations and shared, public, and encountered systems. The final decision may rest on commercial practicality, and several new technologies are explored. Ultimately, we need to continue to move forward both on the universal design and the assistive technology fronts if we are to address the needs of people with disabilities and those who are aging.

Assessing clinical handover between paramedics and the trauma team

Introduction

The aim of effective clinical handover is seamless transfer of information between care providers. Handover between paramedics and the trauma team provides challenges in ensuring that information loss does not occur. Handover is often time-pressured and paramedics’ clinical notes are often delayed in reaching the trauma team. Documentation by trauma team members must be accurate. This study evaluated information loss and discordance as patients were transferred from the scene of an incident to the Trauma Centre.

Methods

Twenty-five trauma patients presenting by ambulance to a tertiary Emergency and Trauma Centre were randomly selected. Audiotaped (pre-hospital) and videotaped (in-hospital) handover was compared with written documentation.

Results

In the pre-hospital setting 171/228 (75%) of data items handed over by paramedics to the trauma team were documented and in the in-hospital handover 335/498 (67%) of information was documented. Information least likely to be documented by trauma team members (1) in the pre-hospital setting related to treatment provided and (2) in the in-hospital setting related to signs and symptoms. While 79% of information was subsequently documented by paramedics, 9% (n = 59) of information was not documented either by trauma team members or paramedics and constitutes information loss. Information handed over was not congruent with documentation on seven occasions. Discrepancies included a patient's allergy status and sites of injury (n = 2). Demographic details were most likely to be documented but not handed over by paramedics.

Conclusion

By documenting where deficits in handover occur we can identify points of vulnerability and strategies to capture this information.
