Cancer survivorship research faces several recruitment challenges, such as accrual of a representative sample, as well as participant retention. Our study explores patterns in recruited demographics, patient-reported outcomes (PROs), and retention rates for a randomized controlled trial (RCT) utilizing a mobile mindfulness intervention for the well-being of cancer survivors. In total, 123 participants were recruited using traditional and online strategies. Using the chi-square test of independence, recruitment type was compared with demographic and clinical variables, PROs, and retention at Time 2 and Time 3. Online recruitment resulted in almost double the yield compared to traditional recruitment. Online-recruited participants were more often younger, from the continental U.S., Caucasian, diagnosed and treated less recently, at a later stage of diagnosis, diagnosed with blood cancer, without high blood pressure, and with less reported pain. The recruitment method was not significantly associated with retention. Online recruitment may capture a larger, broader survivor sample, but, similar to traditional recruitment, may also lead to selection biases depending on where efforts are focused. Future research should assess the reasons underlying the higher yield and retention rates of online recruitment and should evaluate how to apply a mix of traditional and online recruitment strategies to efficiently accrue samples that are representative of the survivor population.

Background/Objectives: Efficient sperm separation is critical for Assisted Reproductive Technology (ART). This study evaluates how assisted liquefaction (AL), a faster sperm preparation technique, affects motile sperm recovery and ART outcomes. Methods: A prospective pair analysis to address the efficiency of AL and retrospective cohort analysis of IUI and IVF/ICSI cycles were performed. Results: The average time to perform AL was 3 min, in comparison to the 15 to 30 min for traditional liquefaction (TL) until initiating sperm preparation. The total motility (p = 0.252) and progressive motility (p = 0.227) of the sperm samples were about 4% higher in the AL group although there was no significant difference. No significant differences were observed between AL and TL in fertilization (80.0% vs. 81.9%, p = 0.297), blastocyst rates (48.2% vs. 48.1%, p = 0.595), positive pregnancy (70.5% vs. 75.0%, p = 0.667), clinical pregnancy (65.9% vs. 68.4%, p = 0.841), or live birth (52.3% vs. 51.3%, p = 0.831) outcomes in IVF. The Positive pregnancy (p = 0.669) and clinical pregnancy (p = 0.841) of IUI were not significantly different between both groups. Conclusions: AL offers similar results to TL while reducing preparation time without interrupting ART outcomes. AL may have benefit to asthenozoospermia cases for ART due to reduced exposure time of sperm to semen that may prevent sperm quality impact.
