(Medical College of Wisconsin) Addressing the nation's continuing poor performance in cancer clinical trial participation, particularly among racial and ethnic minorities and low income groups, will require meaningful public involvement in the design and implementation of clinical trials, according to a landmark report released today.

| • | Influence of Cracking on Rice Seasons and Irrigation in Bangladesh |
| Winter dry season is mainly depends on irrigation. Because, the rainfall in this season is almost zero. At the end of this season, ground water mainly remains at about 10-12 meter depth. On the other hand, the crop then remains at booting to flowering stages. During this period, a huge number of cracks developed on the puddled field due to shortage of water. Consequently, the size and number of cracks depend on the irrigation interval, the intensity and duration of drought spell. The sizes of the cracks are range about 10-30 mm wide. Normally, the major cracks goes below puddled layer of 70-100 mm and almost all the cracks are interlinked and remain active through the growing season. Therefore, a major portion of the irrigation water lost through this cracks. Hence, a large area remains fallow due to proper management and shortage of irrigation water. Therefore, irrigation application efficiency to be increased in cracking soils by reducing seepage and drainage losses in paddies. As a result, it is important to develop irrigation scheduling of rice for cracking soils on the basis of crack size rather than estimating crop water requirements based on evapotranspiration (ET) demand. | |

| • | Extracting key information from historical data to quantify the transmission dynamics of smallpox |
| Background: Quantification of the transmission dynamics of smallpox is crucial for optimizing intervention strategies in the event of a bioterrorist attack. This article reviews basic methods and findings in mathematical and statistical studies of smallpox which estimate key transmission parameters from historical data.Main findingsFirst, critically important aspects in extracting key information from historical data are briefly summarized. We mention different sources of heterogeneity and potential pitfalls in utilizing historical records. Second, we discuss how smallpox spreads in the absence of interventions and how the optimal timing of quarantine and isolation measures can be determined. Case studies demonstrate the following. (1) The upper confidence limit of the 99th percentile of the incubation period is 22.2 days, suggesting that quarantine should last 23 days. (2) The highest frequency (61.8%) of secondary transmissions occurs 3?5 days after onset of fever so that infected individuals should be isolated before the appearance of rash. (3) The U-shaped age-specific case fatality implies a vulnerability of infants and elderly among non-immune individuals. Estimates of the transmission potential are subsequently reviewed, followed by an assessment of vaccination effects and of the expected effectiveness of interventions. Conclusion: Current debates on bio-terrorism preparedness indicate that public health decision making must account for the complex interplay and balance between vaccination strategies and other public health measures (e.g. case isolation and contact tracing) taking into account the frequency of adverse events to vaccination. In this review, we summarize what has already been clarified and point out needs to analyze previous smallpox outbreaks systematically. | |
