Pre-vaccination incidence of genital warts in 15-23-year-old women and men attending youth clinics in Stockholm, Sweden

Abstract Background: Human papillomavirus (HPV) vaccines were introduced to the market in 2006 and 2007. The present pilot study was designed to examine the incidence of genital warts in the population up to 23 y of age in the county of Stockholm before the start of mass HPV vaccination. Methods: Data from the electronic health records of 9 youth clinics in the county of Stockholm were collected retrospectively for the y 2006-2008. Results: In total, 49,985 patients visited the study youth clinics during 2006-2008. Of these, 1817 were denoted genital warts patients. An extrapolation of the study data was done in an attempt to estimate the annual number of genital warts cases in the full Stockholm County population aged 15-23 y. Results showed that there were approximately 1792 genital warts patients in the age group 15-23 y each year in Stockholm County. Female cases represented approximately 62% of all cases in the age group 15-23 y. The peak incidence was at around 20 y of age for females, while males had a more flattened peak incidence around 19-23 y of age. Conclusion: This pilot study demonstrates that, compared to other reported data, genital warts are at least as common in Sweden as in other countries among 15-23 y old females and males.     

Associations between inflammatory markers, candidate polymorphisms and physical performance in older Danish twins

Inflammation may play an essential role in the decline of physical performance. In this study we investigated the associations between inflammatory markers, candidate polymorphisms and physical performance in elderly people. Plasma levels of TNF-α, IL-6, CRP, fibrinogen, sICAM-1 and candidate polymorphisms were measured in 600 twin individuals aged 73 years and older participating in the Longitudinal Study of Aging Danish Twins. Physical performance was assessed using a self-reported measure. The inclusion of twins allowed both traditional and within-twin-pair analysis which permitted control for shared environment and genetic factors. Higher levels of inflammatory markers were generally associated with a lower level of physical performance. The TNFα-238G/A polymorphism was significantly associated with physical performance in men, with A allele carriers having significantly better performance than GG homozygotes. However, this gene variation seems to have only a minor role in explaining the associations between the levels of inflammatory markers and physical performance. When using twin pair analysis to test whether genetic factors in general account for this association, results showed that the association between the level of fibrinogen and physical performance could be caused by genetic factors. Also the association between the level of TNF-α and physical performance in males could be caused by genetic factors. However, other gene variations than the candidate gene polymorphisms studied here seem to explain the major part of the genetic proportion of this association.
