New literacy challenge for the twenty-first century: genetic knowledge is poor even among well educated

We live in an age of rapidly advancing genetic research. This research is generating new knowledge that has implications for personal health and well-being. The present study assessed the level of genetic knowledge and personal engagement with genetics in a large sample (N = 5404) of participants. Participants received secondary education in 78 countries, with the largest samples from Russia, the UK and the USA. The results showed significant group differences in genetic knowledge between different countries, professions, education levels and religious affiliations. Overall, genetic knowledge was poor. The questions were designed to assess basic genetic literacy. However, only 1.2% of participants answered all 18 questions correctly, and the average score was 65.5%. Genetic knowledge was related to peoples’ attitudes towards genetics. For example, those with greater genetic knowledge were on average more willing to use genetic knowledge for their personal health management. Based on the results, the paper proposes a number of immediate steps that societies can implement to empower the public to benefit from everadvancing genetic knowledge

Fibrinogen and inflammatory cytokines in spontaneous sputum of sulfur-mustard-exposed civilians - Sardasht-Iran Cohort Study

Sulfur mustard (SM) causes late complications in respiratory system of exposed individuals. In this preliminary study, the levels of IL-1 alpha and beta, TNF, IL-1Ra, IL-6 and fibrinogen in the spontaneous sputum of SM-exposed individuals were examined 20 years after exposure and the correlation with pulmonary function was tested. The participants were categorized into two major subgroups (hospitalized and non-hospitalized) based on the severity of the clinical complications immediately after exposure. Every participant was visited by a physician; the respiratory functions were checked using spirometry and were categorized as normal, mild, moderate or severe pulmonary complications. The levels of cytokines in the sputum and serum samples were measured using ELISA method. The mean values of TNF, IL-1 alpha and IL-1 beta were 524.15, 115.15, 1951.33 pg/ml respectively, and the mean levels of IL-1Ra and IL-6 were 6410.52 and 124.44 pg/ml respectively; fibrinogen was 71.59 ng/ml and index of IL-Ra/IL-1 beta was 7.78. There was more TNF-alpha and IL-1 beta and less IL-1Ra and fibrinogen in the sputum of the hospitalized subgroup. The level of TNF-alpha and IL-1 beta also increased in moderate and severe pulmonary status comparing with the group with mild disorders, while fibrinogen was lower or decreased significantly in problematic patients. IL-1 beta and TNF showed positive correlation (r=0.5, and r=0.59, respectively); fibrinogen and IL1Ra/IL-1 beta have negative correlation with lung function according to the GOLD classification (r=-0.4, and r=-0.61, respectively). It is concluded that sputum cytokines and fibrinogen, reflect the degree of the severity of airway inflammation and the cytokine levels in the sputum might be completely different from the serum fluctuations.
