Evaluating user experience with respect to user expectations in brain-computer interface games

Evaluating user experience (UX) with respect to previous experiences can provide insight into whether a product can positively aect a user's opinion about a technology. If it can, then we can say that the product provides a positive UX. In this paper we propose a method to assess the UX in BCI systems with respect to user expectations. We demonstrate the application of our method in a preliminary study. The study results showed that BCI game control was natural and enjoyable despite the low reliability of the BCI. However SSVEP based selection induced fatigue on participants. The proposed method can extract the right and wrong practices to employ BCI in applications and can suggest interaction paradigms or considerations to follow when developing BCI systems

Influence of music therapy on coping skills and anger management in forensic psychiatric patients: An exploratory study

The effect of music therapy on anger management and coping skills is an innovative subject in the field of forensic psychiatry. This study explores the following research question: Can music therapy treatment contribute to positive changes in coping skills, anger management, and dysfunctional behavior of forensic psychiatric patients? To investigate this question, first a literature review is offered on music therapy and anger management in forensic psychiatry. Then, an explorative study is presented. In the study, a pre- and post-test design was used with a random assignment of patients to either treatment or control condition. Fourteen participants’ complete datasets were collected. All participants received “treatment as usual.” Nine of the participants received a standardized, music therapy anger management program; the five controls received, unplanned, an aggression management program. Results suggested that anger management skills improved for all participants. The improvement of positive coping skills and diminishing of avoidance as a coping skill were measured to show greater changes in music therapy participants. When controlling for the exact number of treatment hours, the outcomes suggested that music therapy might accelerate the process of behavioral changes

Word reading in monolingual and bilingual children with developmental language disorder

Many children with developmental language disorder (DLD) are reported to have word reading difficulties. However, previous research has focused mostly on monolingual children. The present study used two existing datasets to assess word reading outcomes of bilingual children with DLD. In Study 1, we compared word reading outcomes of monolingual and bilingual children with and without DLD (n = 93 monolingual DLD; n = 33 bilingual DLD, n = 42 monolingual TD; n = 74 bilingual TD). In Study 2, we compared those of monolingual (n = 91) and bilingual children with DLD (n = 51) on the basis of school record data. Findings from both studies show mean poor word reading outcomes and a high incidence of poor readers in the groups of children with DLD. Despite lower oral language outcomes of bilingual children in the mainstream language, reading outcomes of monolingual and bilingual children (with/without DLD) did not differ or outcomes were even better for the bilingual children. Overall, these findings indicate that DLD is a risk factor for word reading difficulties, while bilingualism is not

Anterior colporrhaphy does not induce bladder outlet obstruction

We aimed to evaluate if anterior colporrhaphy causes incomplete voiding due to bladder outlet obstruction. Women scheduled for anterior colporrhaphy were asked to undergo multichannel urodynamic investigation before surgery and the first postoperative day. Bladder outlet obstruction was assessed using the Blaivas-Groutz voiding nomogram. Maximum flow rate, detrusor pressure and residual volume were compared between pre- and postoperative measurements and between women with and without an abnormal post-void residual volume (PVR; volume exceeding 150 ml). Seventeen women participated. One woman who was unobstructed before surgery was obstructed after surgery. Overall, detrusor pressure and maximum flow rate before and after surgery did not differ. After surgery, six women had an abnormal PVR, one was unable to void, four were mildly obstructed and one moderately obstructed. Urodynamic investigation the first day after anterior colporrhaphy did not show that anterior colporrhaphy induces bladder outlet obstruction. The explanation for postoperative urinary retention can therefore also lie in non-anatomical causes such as postoperative pain and psychological factor

Feasibility of Live-Performed Music Therapy for Extremely and Very Preterm Infants in a Tertiary NICU

Objective: We aimed to investigate the feasibility of live-performed music therapy for extremely and very preterm infants admitted to the neonatal intensive care unit (NICU), and their parents, starting the 1st-2nd week after birth. They may benefit from live-performed music therapy as comforting non-pharmacological intervention. Study Design: We included infants born before 30 weeks' gestation in a single center NICU study. Live-performed music therapy was provided three times per week, tailored to the infant's medical condition. Parents were actively involved. Feasibility was determined as a combination of participation, drop-out, overstimulation (based on COMFORT-Neo scores), and evaluations of the intervention by parents and nurses (using a questionnaire on perceived effects on the parent, their infant and the NICU sound environment). Results: We included 18 infants (90% participation rate), with a gestational age of median 27 weeks (IQR 26-28 weeks), 61% males. One infant (5.6%) dropped-out. Differences of COMFORT-Neo scores during and after sessions compared with before sessions were non-significant; overstimulation by music therapy did not occur. Parents reported high satisfaction (highest score possible of 7) with the interventions and reported improvements in both infant and their own respiratory rates. Nurses also reported high satisfaction with the intervention and perceived a quieter NICU sound environment during and after sessions. Conclusion: Live-performed music therapy for extremely and very preterm infants is feasible and well-tolerated, and is experienced as an added value to developmental care. Future studies should assess both short-term and long-term effects, to determine whether this intervention should be part of routine care at the NICU and whether it is most beneficial to start shortly after birth

A nationwide survey to measure practice variation of catheterisation management in patients undergoing vaginal prolapse surgery

Urinary catheterisation following vaginal prolapse surgery causes inconvenience for patients, risk of urinary tract infections and potentially longer hospitalisation. Possibly, practice variation exists concerning diagnosis and management of abnormal postvoid residual (PVR) volume implying suboptimal treatment for certain subgroups. Nationwide questionnaire-based survey. Post-operatively, 77% performed transurethral indwelling catheterisation, 12% suprapubic catheterisation and 11% intermittent catheterisation. Catheterisation was applied 3 days (1-7 days) following anterior repair and 1 day (1-3 days) following all other procedures. The median cut-off point for abnormal PVR was 150 mL (range 50-250 mL). Treatment of abnormal PVR consisted mostly of prolonging transurethral indwelling catheterisation for 2 days (range 1-5 days; 57%), 29% by intermittent and 12% by suprapubic catheterisation. Antibiotics were administered by 21% either routinely or based on symptoms only. Due to insufficient evidence and suboptimal implementation of available evidence, practice variation in catheterisation regimens is hig

Fasting induces a biphasic adaptive metabolic response in murine small intestine

BACKGROUND: The gut is a major energy consumer, but a comprehensive overview of the adaptive response to fasting is lacking. Gene-expression profiling, pathway analysis, and immunohistochemistry were therefore carried out on mouse small intestine after 0, 12, 24, and 72 hours of fasting. RESULTS: Intestinal weight declined to 50% of control, but this loss of tissue mass was distributed proportionally among the gut's structural components, so that the microarrays' tissue base remained unaffected. Unsupervised hierarchical clustering of the microarrays revealed that the successive time points separated into distinct branches. Pathway analysis depicted a pronounced, but transient early response that peaked at 12 hours, and a late response that became progressively more pronounced with continued fasting. Early changes in gene expression were compatible with a cellular deficiency in glutamine, and metabolic adaptations directed at glutamine conservation, inhibition of pyruvate oxidation, stimulation of glutamate catabolism via aspartate and phosphoenolpyruvate to lactate, and enhanced fatty-acid oxidation and ketone-body synthesis. In addition, the expression of key genes involved in cell cycling and apoptosis was suppressed. At 24 hours of fasting, many of the early adaptive changes abated. Major changes upon continued fasting implied the production of glucose rather than lactate from carbohydrate backbones, a downregulation of fatty-acid oxidation and a very strong downregulation of the electron-transport chain. Cell cycling and apoptosis remained suppressed. CONCLUSION: The changes in gene expression indicate that the small intestine rapidly looses mass during fasting to generate lactate or glucose and ketone bodies. Meanwhile, intestinal architecture is maintained by downregulation of cell turnove
