Project DIANA - Converging and Integrating IP and ATM for real-time applications

The evolution of IP and ATM share some common drivers. Both of them are addressing efficient network resource utilisation. In order to evaluate the options and combinations offered by these technologies the DIANA project is looking into the areas where ATM and IP both overlap and complete each other, that is QoS interworking between ATM and IP. This is achieved by investigating RSVP-over-ATM approach. This solution is compared with two IP level approaches: Differentiated Services and Scalable Resource Reservation Protocol (SRP)

Help-seeking behaviour for internalizing problems

Objective Although adolescent girls from ethnic minorities are at an increased risk of internalizing problems (e.g. depression), only a small fraction seeks formal help for these problems. To enhance help-seeking for internalizing problems among ethnic minority adolescent girls, insight into their help-seeking behaviour is required. This study explored the perceptions of adolescent girls from different ethnic backgrounds regarding their help-seeking behaviour for internalizing problems. Design A qualitative study using focus group discussions (FGDs) was employed. Eight ethnic-specific FGDs were conducted with 50 adolescent girls of mostly Turkish (n=23), Moroccan (n=13), and Dutch (n=10) backgrounds recruited in Rotterdam, a multicultural city in the Netherlands. FGDs were conceptually framed within a help-seeking model, facilitated by a vignette and analysed using NVivo software. Results When describing the internalizing problems presented in the vignette, participants of non-Dutch FGDs tended to state the causes of the problems (e.g. lack of attention) whereas participants of Dutch FGDs mentioned the emotional state. Participants did not perceive the presented internalizing problems as severe. If participants were to face internalizing problems of their own, their decision to seek help would be hampered by negative attitudes towards professionals and school-based services. Particularly in non-Dutch FGDs the fear of parental and friend's reactions was identified as a barrier. Participants identified their mother and a good friend as primary sources of help.ConclusionIn this study, adolescent girls of Turkish, Moroccan and Dutch backgrounds had difficulty recognizing the severity of internalizing problems, and various barriers could hamper their decision to seek help. To enhance utilization of mental health services by youth, promoting a change in their attitudes towards mental health/school-based services is recommended. Guaranteeing confidentiality within school-based services, and training for professionals in communicating with adolescent girls, may also prove beneficial. In ethnic minorities, tackling the negative reactions of family/friends requires attention

Effort and work-of-breathing parameters strongly correlate with increased resistance in an animal model

Background: Effort of Breathing (EOB) calculations may be a reliable alternative to Work of Breathing (WOB) calculations in which Respiratory Inductance Plethysmography (RIP) replaces spirometry. We sought to compare EOB and WOB measurements in a nonhuman primate model of increasing extrathoracic inspiratory resistance simulating upper airway obstruction (UAO).Methods: RIP, spirometry, and esophageal manometry were measured in spontaneously breathing, intubated Rhesus monkeys utilizing 11 calibrated resistors randomly applied for 2-min. EOB was calculated breath-by-breath as Pressure Rate Product (PRP) and Pressure Time Product (PTP). WOB was calculated from the Pressure-Volume curve based on spirometry (WOBSPIR) or RIP flow (WOBRIP).Results: WOB, PRP and PTP showed similar linear increases when exposed to higher levels of resistive loads. When comparing WOBSPIR to WOBRIP, a similar strong correlation was seen for both signals as resistance increased and there were no statistically significant differences.Conclusion: EOB and WOB parameters utilizing esophageal manometry and RIP, independent of spirometry, showed a strong correlation as a function of increasing inspiratory resistance in nonhuman primates. This allows several potential monitoring possibilities for non-invasively ventilated patients or situations where spirometry is not available. Impact: EOB and WOB parameters showed a strong correlation as a function of increasing inspiratory resistance in nonhuman primates.There was a strong correlation between spirometry-based WOB versus RIP-based WOB.To date, it has remained untested as to whether EOB is a reliable alternative for WOB and if RIP can replace spirometry in these measurements.Our results enable additional potential monitoring possibilities for non-invasively ventilated patients or situations where spirometry is not available.Where spirometry is not available, there is no need to apply a facemask post extubation to a spontaneously breathing, non-intubated infant to make objective EOB measurements.</p
