Preliminary results using a P300 brain-computer interface speller: a possible interaction effect between presentation paradigm and set of stimuli
Fernández-Rodríguez Á., Medina-Juliá M.T., Velasco-Álvarez F., Ron-Angevin R. (2019) Preliminary Results Using a P300 Brain-Computer Interface Speller: A Possible Interaction Effect Between Presentation Paradigm and Set of Stimuli. In: Rojas I., Joya G., Catala A. (eds) Advances in Computational Intelligence. IWANN 2019. Lecture Notes in Computer Science, vol 11506. Springer, ChamSeveral proposals to improve the performance controlling a P300-based BCI speller have been studied using the standard row-column presentation (RCP) par-adigm. However, this paradigm could not be suitable for those patients with lack of gaze control. To solve that, the rapid serial visual presentation (RSVP) para-digm, which presents the stimuli located in the same position, has been proposed in previous studies. Thus, the aim of the present work is to assess if a stimuli set of pictures that improves the performance in RCP, could also improve the per-formance in a RSVP paradigm. Six participants have controlled four conditions in a calibration task: letters in RCP, pictures in RCP, letters in RSVP and pictures in RSVP. The results showed that pictures in RCP obtained the best accuracy and information transfer rate. The improvement effect given by pictures was greater in the RCP paradigm than in RSVP. Therefore, the improvements reached under RCP may not be directly transferred to the RSVP.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
Integral strategy to supportive care in breast cancer survivors through occupational therapy and a m-health system: design of a randomized clinical trial
Background: Technological support using e-health mobile applications (m-health) is a promising strategy to improve
the adherence to healthy lifestyles in breast cancer survivors (excess in energy intake or low physical activity are
determinants of the risk of recurrence, second cancers and cancer mortality). Moreover, cancer rehabilitation
programs supervised by health professionals are needed due to the inherent characteristics of these breast cancer
patients. Our main objective is to compare the clinical efficacy of a m-health lifestyle intervention system alone versus
an integral strategy to improve Quality of Life in breast cancer survivors.
Methods: This therapeutic superiority study will use a two-arm, assessor blinded parallel RCT design. Women will be
eligible if: they are diagnosed of stage I, II or III-A breast cancer; are between 25 and 75 years old; have a Body Mass
Index > 25 kg/m2; they have basic ability to use mobile apps; they had completed adjuvant therapy except for
hormone therapy; and they have some functional shoulder limitations. Participants will be randomized to one of
the following groups: integral group will use a mobile application (BENECA APP) and will receive a face-to-face
rehabilitation (8-weeks); m-health group will use the BENECA app for 2-months and will received usual care
information. Study endpoints will be assessed after 8 weeks and 6 months. The primary outcome will be Quality
of Life measured by The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core
and breast module. The secondary outcomes: body composition; upper-body functionality (handgrip, Disability of the
Arm, Shoulder and Hand questionnaire, goniometry); cognitive function (Wechsler Adult Intelligence Scale, Trail Making
Test); anxiety and depression (Hospital Anxiety and Depression Scale); physical fitness (Short version of the Minnesota
Leisure Time Physical Activity Questionnaire, Self-Efficacy Scale for Physical Activity); accelerometry and lymphedema.
Discussion: This study has been designed to seek to address the new needs for support and treatment of breast cancer
survivors, reflecting the emerging need to merge new low cost treatment options with much-needed involvement of
health professionals in this type of patients.

The implications of women's activity limitations and role disruptions during breast cancer survivorship.
Early survivorship is a time of critical transition for women survivors of breast cancer as they attempt to resume functional activities and important life roles. This study aimed to explore the challenges of women and their partners as they attempted to resume activities and roles, identify unmet needs and make recommendations regarding a suitable framework to support women and partners to recommence valued activities and important roles during early survivorship. Qualitative methods utilising in-depth interviews of women (n?=?18) and their partners (n?=?8), and two focus groups (n?=?10) were completed in Perth, Western Australia, between June 2014 and April 2015. These methods were used to facilitate women and partners' views regarding the resumption of previously meaningful activities and important life roles during early survivorship. Questions addressed their individual and shared experiences concerning self-care, leisure, social and productive activities and important roles. Thematic analysis was employed to determine themes. Women and partners reported significant impact on their ability to engage in valued activities, resulting in changes to participation in meaningful roles. Three themes were determined: (1) ambiguity regarding survivorship prevents resumption of activities and previous roles, (2) breast cancer continues to impact a couples' relationship during survivorship, and (3) support is needed to assist women and partners to resume activities and important roles. This research provides evidence suggesting that the ongoing symptoms of breast cancer treatment continue to impact many women and their partners, as they attempt to resume functional activities and important life roles during early survivorship. Disruption to these valued activities and roles may influence women and their partner's health and well-being during early survivorship and extend beyond this period. Rehabilitation following cessation of treatment could be offered as required to facilitate access to multi-disciplinary services and supports for both individuals and couples
