MedicalResearch.com: What is the background for this study?

Response: In this study, we investigate the effect of Human Papillomavirus (HPV) vaccination on participation in Pap test, which is one of the most effective cancer screening interventions. Cervical cancers are causally linked to HPV infections. The Pap test is a diagnostic procedure for early detection of cervical cancer. HPV vaccination provides partial protection against cervical cancer, and the Pap test is strongly recommended for women 21 to 65 years of age even after vaccination. If vaccination leads to a reduction in testing participation, it could contribute to greater incidence and severity of cervical cancer. Note that we focus on relatively older women (age 22 or older) who were not vaccinated at younger ages.  Continue reading

TRAP: Traffic Related Air Pollution Linked to Millions of Pediatric Asthma Cases Worldwide

MedicalResearch.com: What is the background for this study?

Response: Dozens of epidemiological studies have found positive and generally statistically significant associations between long-term exposure to traffic-related air pollution (TRAP) and asthma development in children. The evidence is most robust for nitrogen dioxide (NO2), a major component of and commonly used surrogate for the complex TRAP mixture. Recent reviews conducted by the US Environmental Protection Agency and Health Canada concluded that there is “likely a causal relationship” between long-term NO2 exposure and pediatric asthma development.

Using NO2 as a proxy for TRAP, our study provides the first global estimate of the number of new asthma cases among children that are attributable to traffic pollution, using fine spatial-scale global datasets that can resolve within-city and near-roadway NO2 exposures.

MedicalResearch.com: What is the background for this study? What are the main findings?

  • The study provides realistic cost estimates of pivotal clinical trials that establish drug benefits to support FDA approval of 59 new drugs released for marketing in 2015-2016.
  • The median estimated cost was just $19 million, with half of the 138 trials studied clustered between $12 million and $33 million.
  • The highest cost trials–with estimates up to $345 million–were for new drugs that were similar to drugs already available and already proven in treating serious illnesses.
