Background Vital signs are used in emergency care settings in the first assessment of children to identify those that need immediate attention. We aimed to develop and validate vital sign based Manchester Triage System (MTS) discriminators to improve triage of children at the emergency department. Methods and findings The TrIAGE project is a prospective observational study based on electronic health record data from five European EDs (Netherlands (n = 2), United Kingdom, Austria, and Portugal). In the current study, we included 117,438 consecutive children <16 years presenting to the ED during the study period (2012–2015). We derived new discriminators based on heart rate, respiratory rate, and/or capillary refill time for specific subgroups of MTS flowcharts. Moreover, we determined the optimal cut-off value for each vital sign. The main outcome measure was a previously developed 3-category reference standard (high, intermediate, low urgency) for the required urgency of care, based on mortality at the ED, immediate lifesaving interventions, disposition and resource use. We determined six new discriminators for children <1 year and ≥1 year: “Very abnormal respiratory rate”, “Abnormal heart rate”, and “Abnormal respiratory rate”, with optimal cut-offs, and specific subgroups of flowcharts. Application of the modified MTS reclassified 744 patients (2.5%). Sensitivity increased from 0.66 (95%CI 0.60–0.72) to 0.71 (0.66–0.75) for high urgency patients and from 0.67 (0.54–0.76) to 0.70 (0.58–0.80) for high and intermediate urgency patients. Specificity decreased from 0.90 (0.86–0.93) to 0.89 (0.85–0.92) for high and 0.66 (0.52–0.78) to 0.63 (0.50–0.75) for high and intermediate urgency patients. These differences were statistically significant. Overall performance improved (R2 0.199 versus 0.204). Conclusions Six new discriminators based on vital signs lead to a small but relevant increase in performance and should be implemented in the MTS.

Purpose : The aim of this study is to report a case of intraorbital wooden foreign body with intracranial extension to the frontal lobe and its management. Method : This is a descriptive study: A 53 year-old male referred due to wooden stick stucked in the orbital cavity causing protruding eyeball and vital sign instability. Result : Right eye examination revealed light perception visual acuity, with bad light projection and bad color perception, inwardly folded upper eyelid, proptosis, conjunctival chemosis, corneal erosion and edema, dilated pupil with sluggish pupillary light reflex and limited ocular movement in all direction. Vital sign was unstable with decreasing blood pressure, increasing temperature and heart rate. CT Scan showed complete fracture of the orbital roof due to penetration of the wooden stick, pneumoencephalus, cerebral edema and hematoma. Emergency craniotomy was performed to remove the penetrating wooden stick and bone segment in the frontal lobe and fracture repair. Ophthalmologist pulled the remaining stick, released the superior rectus muscle and repaired the lacerated eyelid. Outcome visual acuity was no light perception with lagophthalmos and limited ocular motility. Patient was admitted to Intensive Care Unit one day post-operatively and treated with systemic and topical antibiotic. Conclusion : Any case presenting with intraorbital foreign body must undergo immediate neuroimaging to exclude any intracranial extension, especially in patients with worsening general condition.

Zusammenfassung Hintergrund Zur frühzeitigen Entscheidung in zukünftigen „Integrierten Notfallzentren“, ob eine ambulante oder innerklinische Versorgung indiziert ist, wäre es hilfreich, ein System zu haben, mit dem die Identifizierung von Patienten mit ambulanter Behandlungsindikation möglich ist. In dieser Studie untersuchten wir, ob das Manchester Triage System (MTS) dafür geeignet ist, Patienten zu erkennen, die sicher der ambulanten medizinischen Versorgung zugeteilt werden können. Methode Notaufnahmepatienten der „blauen“ MTS-Dringlichkeitsstufe wurden auf den Endpunkt „stationäre Aufnahme“ untersucht und mit der nächsthöheren MTS-Kategorie „grün“ verglichen. In einem zweiten Schritt wurde die „blaue“ Dringlichkeitsstufe auf die häufigsten gemeinsamen Kriterien untersucht, die zur stationären Aufnahme führten. Ergebnisse Nach Ausschluss von Patienten, die durch den Rettungsdienst oder nach vorherigem Arztbesuch vorstellig wurden, war die Rate der stationären Aufnahmen in der blauen Dringlichkeitsstufe signifikant niedriger als in der grünen Kategorie (10,8 % vs. 29,0 %). Die Rate konnte durch die Etablierung einer Untergruppe mit den zusätzlichen Ausschlusskriterien chronische Erkrankung und Wiedervorstellung nach vorheriger stationärer Behandlung auf 0,9 % gesenkt werden. (CEReCo-blue-Gruppe: Chronic Disorder (C), Emergency Medical Service (E), Readmission (R), Prior Medical Consultation (Co)). Schlussfolgerung Die blaue MTS-Dringlichkeitsstufe scheint zur Selektion von Patienten mit ambulanter Behandlungsindikation nicht geeignet zu sein. Wir schlagen die Einführung einer Untergruppe, der sog. CEReCo-blue-Gruppe vor, die für die Selektion dieser Patientengruppe hilfreich sein könnte.

AbstractRobotic assembly tasks are typically implemented in static settings in which parts are kept at fixed locations by making use of part holders. Very few works deal with the problem of moving parts in industrial assembly applications. However, having autonomous robots that are able to execute assembly tasks in dynamic environments could lead to more flexible facilities with reduced implementation efforts for individual products. In this paper, we present a general approach towards autonomous robotic assembly that combines visual and intrinsic tactile sensing to continuously track parts within a single Bayesian framework. Based on this, it is possible to implement object-centric assembly skills that are guided by the estimated poses of the parts, including cases where occlusions block the vision system. In particular, we investigate the application of this approach for peg-in-hole assembly. A tilt-and-align strategy is implemented using a Cartesian impedance controller, and combined with an adaptive path executor. Experimental results with multiple part combinations are provided and analyzed in detail.
