Methods: Focus group discussions with 26 American-English speaking and nine American-Spanish speaking children and their parents were conducted, transcribed verbatim and subsequently qualitatively analyzed by two independent raters, using an existing coding guideline, based on the multidimensional HrQoL concept and a special software (VERBI-Software MAXQDA 10). Results: A total of 1313 statements for the English-speaking and 447 statements for the Spanish-speaking families were categorized. In the US, the strongest frequency of mention was found for the HrQoL dimension “Social” across respondents, followed by “Treatment” and “Emotion”. Conclusion: Conducting and analyzing data generated from focus groups ensure that young patients’ experiences of disease are represented in the measure of outcomes for use in clinical trials and patient care.展开更多

This study assessed barriers and facilitators to clinical trials participation by Medicaid eligible Mexican- Americans and their serving physicians. Qualitative data from two focus groups conducted among Mexican-American Medicaid eligible patients and four physician focus groups were analyzed. Mexican-American patients have a basic understanding of clinical trials. While most are open to participating in clinical research, not speaking English, time, and transportation were identified as barriers. Physicians believe that desperation and financial need are the primary patient motivators for participation. Barriers to physician recruitment and referral include: lack of information about clinical trials, concern that study participation may not be in the patient’s best interest, and lack of staffing and time to conduct trials. Ample opportunities exist to engage providers and patients in future efforts to increase Mexican-American patient recruitment into clinical trials.展开更多

Using the open-source software Open FOAM~?, a two-dimensional viscous-flow numerical wave flume was developed to simulate the fluid resonant motions induced by transient focused wave groups with different spectral peak periods and wave amplitudes. The results indicate that for all the incident focused wave amplitudes considered, the amplitudes of the free surface elevation in the gap, horizontal wave force and moment all exhibit a bimodal variation trend with increasing spectral peak period. The peak values of the above amplitude-period curve appear near the resonant period of the first and second harmonic components of the free surface elevation. However, the variation in the vertical wave force versus the spectral peak period presents different patterns. In addition, the first-to fourth-order harmonic components in the wave surface and forces are further examined via the four-phase combination method. The results show that the first-to secondorder harmonic components play a dominant role in the overall amplitude.展开更多
