- Purpose: The aim of this study was to examine how parents of very low birth weight (VLBW) infants experienced having their newborn infant enrolled in a randomized controlled intervention trial (RCT). Design and Methods: A qualitative descriptive design was used. Data were collected through individual semi-structured interviews with 15 parents of 9 participating VLBW infants. The data were then made the object of an inductive qualitative content analysis. Results: The parents expressed trust in the competence and motivation of the researchers and were confident that participating in the project would do no harm, but instead would potentially benefit their infant. The parents felt privileged for being given the chance to participate, to commit to the project; they were willing to invest their time and effort in the project. Participation could be stressful for the parents, ranging from minor irritation to situations in which they felt overwhelmed and not entirely in control. Many families lived stressful lives, and participation, particularly the follow-up after being discharged, may have added to this. Conclusions: Infant participation in an RCT can be a positive experience, making the parents feel that they are given a chance to both contribute and receive something special. Participation can also be stressful because of conditions both related and unrelated to the RCT. Practice Implications: We identified several issues that researchers in future trials with VLBW infants need to address to minimize parental stress. Recruitment to intervention studies within the immediate period around birth should be avoided, if possible.

- We analyze observations of an SEP event at Rosetta’s target comet 67P/Churyumov-Gerasimenko during March 6th-10th 2015. The comet was 2.15AU from the Sun, with the Rosetta spacecraft approximately 70km from the nucleus placing it deep inside the comet’s coma and allowing us to study its response. The Eastern flank of an ICME also encountered Rosetta on March 6th and 7th. Rosetta’s RPC data indicate increases in ionization rates, and cometary water group pickup ions exceeding 1keV. Increased charge exchange reactions between solar wind ions and cometary neutrals also indicate increased upstream neutral populations consistent with enhanced SEP induced surface activity. In addition, the most intense parts of the event coincide with observations interpreted as an infant cometary bow shock, indicating that the SEPs may have enhanced the formation and/or intensified the observations. These solar transient events may also have pushed the cometopause closer to the nucleus.We track and discuss characteristics of the SEP event using remote observations by SOHO, WIND and GOES at the Sun, in-situ measurements at STEREO A, Mars and Rosetta, and ENLIL modeling. Based on its relatively prolonged duration, gradual and anisotropic nature and broad angular spread in the heliosphere, we determine the main particle acceleration source to be a distant ICME which emerged from the Sun on March 6th 2015 and was detected locally in the Martian ionosphere but was never encountered by 67P directly. The ICME’s shock produced SEPs for several days which traveled to the in-situ observation sites via magnetic field line connections.
