  abstract  = {In der neurologischen Rehabilitation werden in zunehmendem Maße tracheotomierte Patienten mit schweren Dysphagien behandelt. Daher sollte den hierzu bisher entwickelten Interventionsverfahren eine evidenzbasierte Grundlage gegeben werden. In der vorliegenden Arbeit wird ein multidisziplin{\"a}rer Behandlungsansatz zur Trachealkan{\"u}lenentw{\"o}hung und Dekan{\"u}lierung vorgestellt, der auf der Grundlage der relevanten Forschungsliteratur und klinischen Beobachtungen entwickelt wurde. Des Weiteren wird erstmals eine systematische Evaluation eines multidisziplin{\"a}ren Trachealkan{\"u}lenmangements vorgenommen und es werden explorative Daten zum Rehabilitationsverlauf dargestellt. In einem retrospektiven Vergleich wurden hierzu die Dekan{\"u}lierungs- und Komplikationsraten sowie die Dauer der Trachealkan{\"u}lenentw{\"o}hnung zweier Patientengruppen gegen{\"u}bergestellt, die vor bzw. nach Einf{\"u}hrung des beschriebenen multidisziplin{\"a}ren Trachealkan{\"u}lenmanagements im REHAB Basel, Schweiz, behandelt wurden. Der rehabilitative Verlauf der multidisziplin{\"a}r behandelten Gruppe wurde mittels der Messinstrumente FIM (Functional Independence Measure) und EFA (Early Functional Abilities) untersucht. Der Vergleich der Dekan{\"u}lierungs- und Komplikationsraten ergab eine vergleichbare Effektivit{\"a}t der beiden Behandlungsans{\"a}tze. Dar{\"u}ber hinaus zeigte sich eine signifikante Verk{\"u}rzung der Kan{\"u}lenentw{\"o}hnungsphase bei Anwendung des multidisziplin{\"a}ren Vorgehens, so dass dieses als effizenter zu beurteilen ist. Die Verlaufsanalyse der multidisziplin{\"a}r behandelten Patienten ergab erst nach der Dekan{\"u}lierung einen signifikanten Zuwachs der funktionellen Selbst{\"a}ndigkeit in Alltagsaktivit{\"a}ten. Bei der Mehrzahl der Patienten konnte ein vollst{\"a}ndiger oraler Kostaufbau nach der Dekan{\"u}lierung erreicht werden.},

  abstract  = {Invasive alien species pose a great threat to the integrity of natural communities by competition with and predation on native species. In Germany the invasive raccoon dog (Nyctereutes procyonoides) and the native red fox (Vulpes vulpes) occupy a similar ecological niche. Therefore, the aim of our study was to discover the extent of exploitative diet competition between these two generalist carnivores. Carcasses of red foxes (n=256) and raccoon dogs (n=253) were collected throughout Mecklenburg Western-Pomerania (north-east Germany) and stomachs contains were analysed. Frequency of occurrence and biomass share indicate that both canids are omnivorous and pursue opportunistic feeding strategies. Small mammals and edible plant material were the most important food resources for red foxes and raccoon dogs. Nonetheless, interspecies differences were recorded for edible plant material, small mammals and insects. While red foxes mostly feed on voles, raccoon dogs consumed mice and shrews as often as voles. Only raccoon dogs preyed on amphibians. There were no differences in carrion consumption, both species scavenged on wild boar and we found clear competition for carrion year-round. Moreover, there was evidence that two red foxes foraged on raccoon dogs and vice versa. The mean annual interspecies diet overlap index was relatively high. The diets determined for raccoon dogs and red foxes were quite similar and a similar food niche breadth was recorded. However, only minor competition is assumed to take place since differences in feeding habits do exist.},

  abstract  = {Background Simple water-swallowing screening tools are not predictive of aspiration and dysphagia in patients with Parkinson's Disease (PD). We investigated the diagnostic accuracy of a multi-texture screening tool, the Gugging Swallowing Screen (GUSS) to identify aspiration and dysphagia/penetration in PD patients compared to flexible endoscopic evaluation of swallowing (FEES). Methods Swallowing function was evaluated in 51 PD participants in clinical 'on-medication' state with the GUSS and a FEES examination according to standardized protocols. Inter-rater reliability and convergent validity were determined and GUSS- and FEES-based diet recommendations were compared. Key Results Inter-rater reliability of GUSS ratings was high (r(s) = 0.8; p < 0.001). Aspiration was identified by the GUSS with a sensitivity of 50\%, and specificity of 51.35\% (PPV 28\%, NPV 73\%, LR+ 1.03, LR- 0.97), dysphagia/penetration was identified with 72.97\% sensitivity and 35.71\% specificity (PPV 75\%, NPV 33.33\%, LR+ 1.14, LR- 0.76). Agreement between GUSS- and FEES-based diet recommendations was low (r(s) = 0.12, p = 0.42) with consistent NPO (Nil per Os) allocation by GUSS and FEES in only one participant. Conclusions and Inferences The multi-texture screening tool GUSS in its current form, although applicable with good inter-rater reliability, does not detect aspiration in PD patients with acceptable accuracy. Modifications of the GUSS parameters "coughing," "voice change" and "delayed swallowing" might enhance validity. The GUSS' diet recommendations overestimate the need for oral intake restriction in PD patients and should be verified by instrumental swallowing examination.},

  abstract  = {Objective: Tracheotomized patients often suffer from impairments in mucociliary clearance and limited capacities for active expectoration of secretions. We investigated the effects of a specific respiratory intervention method (bagging) for tracheotomized patients on respiratory parameters (pO(2), pCO(2), SpO(2), respiratory rates), swallowing frequency, vigilance and secretion viscosity. Methods: The bagging method supports enforced mobilization and expectoration of secretions by application of a series of manual hyperinflations with a resuscitation bag during active inspiration and manual cough support on the chest. 30 tracheotomized neurological patients participated in a multiple-baseline study including a three-weeks intervention period and a follow-up measurement three weeks after termination of the treatment. Results: Most outcome parameters improved significantly during the intervention period: pO(2) (p<.01), SpO(2) (p<.01), respiratory rates (p<.01), swallowing rates (p<.01), and vigilance scores (p<.01). The quality of bronchial secretions improved in all participants. All effects were sustained up to the follow-up measurements. Conclusion: This preliminary data indicates positive effects for a respiratory intervention method (bagging) on respiratory function and additional respiration-related functions in tracheotomized neurological patients. This easy-to-learn and inexpensive method might expand the range of treatment options for tracheotomized and non-responsive patients.},
