Issue 27, July 9, 2012

Vol. 4, Issue: 27, 7/9/12

The report consists of four components:

  • Top Ten Articles of the Week
  • CDC-authored publications
  • Key scientific articles in featured topic areas (this week featuring Public Health Ethics)
  • Public health articles noted in the media

Diverse aspects of public health harms related to tobacco lead off this week’s featured articles. After conducting a field investigation of Green Tobacco Sickness in Brazil, P Bartholomay and colleagues conclude that occupational health interventions are needed in tobacco-growing regions. In an analysis published in the American Journal of Public Health, MF Pesko, J Kruger and A Hyland find that adult smokers vary in their use of price minimization strategies, such as purchasing cigarettes in states with lower prices.

Environmental factors-broadly defined- may be of harm or benefit to the individual and to public health. According to data from NHANES, C Ayala and colleagues note that adults with hypertension who attempt to reduce their sodium intake still have average sodium consumption well above recommended levels. While all-terrain vehicle (ATV) related deaths are increasing, data from JC Helmkamp and collaborators indicate that helmet-use requirements may be protective.

HIV and other bloodborne pathogens remain persistent concerns for both the public health and healthcare workforces. HIV posttest counseling either was not documented or did not occur in nearly half of more than 370,000 tests conducted at 24 health department STI clinics, according to E Begley and M Vanhandel. The economics of HIV testing is addressed by PG Farnham, SL Sansom and AB Hutchinson, who write that screening for HIV is cost-effective across a range of testing costs. Inadequate response to exposure to bloodborne pathogens might increase risk for healthcare workers employed in dialysis facilities, according to a policy and practice assessment undertaken by C Mbaeyi et al.

An infectious disease potpourri concludes Science Clips features for the week. An evaluation of the ArboNET surveillance system, led by NP Lindsey, has resulted in technical improvements and revised case definitions. MH Diaz and JM Winchell report development of real-time PCR for detection of the respiratory pathogens Mycoplasma pneumoniae and Chlamydophila pneumoniae. An investigation of use of the antibiotic metronidazole during pregnancy by CA Koss et al reassuringly found no association with adverse birth outcomes.
