For example, in lymphomas and leukemias, scientists have determined that the growth is controlled by a protein called Bruton's tyrosine kinase (BTK). After years of experimentation, doctors developed a new drug called Ibrutinib that blocks BTK.
A pair of studies in the New England Journal of Medicine this summer found that the oral pill helped 71 percent of chronic leukemia patients and 68 percent of patients with a type of non-Hodgkins lymphoma. Most importantly, Ibrutinib killed off the lymphoma while leaving the rest of the immune system alone.
McCrea et al. (2003) studied the immediate instantaneous symptoms and cognitive recuperation process of concussed collegiate football players (27). The purpose of the study was to assess the critical ramifications of concussion and the progression to restoration of intercollegiate football players. The cohort consisted of 1,631 football student-athletes from 15 National Collegiate Athletic Association (NCAA) Division I, II, and II colleges and universities. This cohort was part of a larger study that occurred during the 1999, 2000, and 2001 seasons and totaled 2,410 participants. All student-athletes in the study experienced a preseason baseline assessment along with a health history questionnaire. The Graded Symptom Checklist (GSC), the Standardized Assessment of Concussion (SAC) and the Balance Error Scoring System (BESS) were utilized to gather outcome measure characteristics. Inaugural data was charted for symptoms, cognition, and balance during the designated timeframe with a 95% confidence interval. Due to the extended length of the surveillance data for the injuries, predictor equation patterns, identity markers, Gaussian residual variation analysis, and an independent correlation matrix were used. This protocol was used to predict the average differences in the final data collected for injured and non-injured players during the designated timeframe (27).
