Our featured article essay returns for 2013, leading off with two articles focusing on tropical diseases. J Sejvarexternal icon and colleagues provide a detailed case series description of nodding syndrome, a form of epidemic epilepsy of as yet unknown etiology. A review of fifteen years of data from the GeoSentinel system led by M Jenseniusexternal icon finds that out of more than 3,500 cases of life-threatening travel-acquired illnesses, the vast majority were due to either falciparum malaria or enteric (typhoid) fever.

Travelers are not the only “special population” of interest to the public health community. A nationwide analysis conducted in Norway of influenza vaccination of pregnant women during the 2009-2010 H1N1 pandemic, authored by SE Habergexternal icon et al, shows that vaccination reduced the risk of maternal influenza and may have reduced the risk of influenza-associated fetal death. A cohort study conducted in Botswana by T Sibandaexternal icon and collaborators documents high tuberculosis cure and treatment completion rates in HIV-positive adults who had received preventive therapy with isoniazid.

Turning to food and nutrition issues, Behavioral Risk Factor Surveillance system data analyzed by KA Grimmexternal icon and colleagues from CDC’s Division of Nutrition, Physical Activity, and Obesity indicates that survey respondents of lower socioeconomic status were less likely to consume fruits at least two times daily or vegetables at least three times daily. The authors discuss potential consumer and environment oriented interventions. Modeled data published by HC Hamnerexternal icon et al from CDC’s National Center on Birth Defects and Developmental Disabilities indicated that fortification of corn masa flour with folic acid would not increase the small proportion of the population (~ 2.5%) with folic acid intake higher than the “tolerable upper intake level”.

One of our New Years’ resolutions for Science Clips is to more prominently feature the outstanding work of public health laboratory scientists. As part of a series of featured articles in Antiviral Therapy, a group led by LM Ganova-Raevaexternal icon summarizes the multiple uses of mass spectrometry for molecular surveillance of hepatitis B and C infections. JS Rotaexternal icon, working with CDC and New York City Department of health co-investigators, compares the sensitivity of different mumps laboratory diagnostic methods using outbreak-associated samples.

January often brings summaries of important data from the prior year, as well as reminders of basic methods underlying public health research and surveillance. The former is exemplified by the American Cancer Society’s 2013 statistical summaryexternal icon, which indicates the continued decline of death rates for lung, breast, colorectal and prostate cancers. The latter includes the contribution by RL Sinkowitz-Cochranexternal icon, who provides a useful summary of survey research principles and practical considerations.
