The dose estimates generated through triage scoring by this network were acceptable for emergency biological dosimetry. When this network is fully operational, it will be the first of its kind in Canada able to respond to radiological/nuclear emergencies by providing triage quality biological dosimetry for a large number of samples. This network represents an alternate expansion of existing international emergency biological dosimetry cytogenetic networks.

The goals of this study were twofold. First, we assessed if waking salivary hormone profiles are altered by nighttime noise exposure in a laboratory environment. Second, we evaluated the potential influence that sleeping in the lab in itself may have had on salivary biomarkers, by comparing results obtained following sleep at home. Twelve adults (7 males, 5 females) between 19-25 yrs slept at home and in a sleep laboratory. Subjects provided six saliva samples during waking hours on the day prior to sleep in the lab, on both days after sleeping in the lab and on the day following the resumption of sleep at home. Following one night of adaptation, subjects were exposed throughout the 2nd night to simulated backup alarms that consisted of trains of 5 consecutive 500 ms duration audible tones. The time between the onset of each tone was 1 s and the time between trains (offset to onset) was 15 to 20 s. When compared to home conditions, cortisol and melatonin levels were higher following sleep in the laboratory 30 minutes after awakening. However, no significant differences were noted for any salivary biomarker between the 1st and 2nd night in the sleep lab, suggesting that these endpoints were not influenced by exposure to noise on the 2nd night. Waking profiles of alpha-amylase were not influenced by where the subjects slept. Subjective reports of sleep disturbance following sleep in the lab were also obtained. For most of the day there was no apparent influence of the laboratory noise exposure. However, subjects did report more sleepiness during the evening (8 pm) following the 2nd night in the laboratory. In general, overall sleep quality was rated slightly higher upon awakening from sleep at home. Factors that might have contributed to the observations in this study are discussed, including those related to the potentially non-representative sample.

Even with the passage of time, the misguided motivations of highly educated, physician-participants in the genocide known as the Holocaust remain inexplicable and opaque. Typically, the physician-patient relationship inherent within the practice of medicine, has been rooted in the partnership between individuals. However, under the Third Reich, this covenant between a physician and patient was displaced by a public health agenda that was grounded in the scientific theory of eugenics and which served the needs of a polarized political system that relied on this hypothesis to justify society’s racial hygiene laws. As part of the National Socialist propaganda, Adolf Hitler ominously argued that the cultural decline of Germany after World War I could largely be based on interbreeding and a “resultant drop in the racial level.” This foundational premise defined those who could be ostracized, labeled and persecuted by society, including those who were assimilated. The indoctrination and implementation of this distorted social policy required the early and sustained cooperation and leadership of the medical profession. Because National Socialism promised it could restore Germany’s power, honor and dignity, physicians embraced their special role in the repair of the state. This article will explore the imperative role, moral risks and deliberate actions of physicians who participated in the amplification process from “euthanasia” to systemic murder to medically-sanctioned genocide. A goal of this analysis will be to explore what perils today’s physicians would face if they were to experience the transitional and collective behaviors of a corrupted medical profession, or if they would, instead, have the fortitude and courage necessary to protect themselves against this collaboration. Our premise is that an awareness of history can serve as a safeguard to the conceit of political ascendency and discrimination.

An ideological case study based on medical profession norms during the Third Reich will be used to exemplify the importance of diversity in the manifestations of professional ethics. The German professional medical community banned their Jewish colleagues from treating German citizens. This included legally mandated employment discrimination and outright censure which led to a professional ethic devoid of diverse voices. While the escalation to the T-4 program and medicalized genocide was influenced by many causes, the intentional, ethnocentric-based exclusion of voices was an important contributing element to the chronicled degradation of societal mores. For illustration, six core Jewish values—life, peace, justice, mercy, scholarship, and sincerity of intention—will be detailed for their potential to inspire health-care professionals to defend and protect minorities and for readers to think critically about the role of medical professionalism in Third Reich society. The Jewish teachings highlight the inherent professional obligations physicians have toward their patients in contrast to the Third Reich’s corruption of patient-centered professionalism. More fundamentally, juxtaposing Jewish and Nazi teachings exposes the loss of perspective when a profession’s identity spurns diversity. To ensure respect for persons in all vulnerable minorities, the first step is addressing professional inclusion of minority voices.
