Blood Lead Toxicity Analysis of Multipurpose Canines and Military Working Dogs.

Special Operations Forces and their accompanying tactical multipurpose canines (MPCs) who are involved in repeated live-fire exercises and military operations have the potential for increased blood lead levels and toxicity due to aerosolized and environmental lead debris. Clinical lead-toxicity symptoms can mimic other medical disorders, rendering accurate diagnosis more challenging. The objective of this study was to examine baseline lead levels of MPCs exposed to indoor firing ranges compared with those of nontactical military working dogs (MWDs) with limited or no exposure to the same environment.

Occurrence of exercise dependence in a college-aged population.

Students (n = 257) were evaluated for scope and commitment to physical activity by use of self-reported data that assessed amount of activity per week and the obligatory or pathological nature of their activity patterns. Exhibiting atypical activity patterns, 21.8% of the students in the sample exercised 360 or more minutes per week and demonstrated at least one exercise "dependent" response pattern to queries about obligatory or pathological exercise.
