Interaktion i särskilt boende för personer med utvecklingsstörning och utmanande beteende
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Bakgrund: Många personer med utvecklingsstörning har kommunikativa svårigheter och har därför behov av att utveckla olika sätt att kommunicera för att kunna förstå andra och göra sig förstådda. Svårigheter i kommunikationen påverkar interaktionen mellan personer med utvecklingsstörning och deras vårdare. Detta ställer höga krav på vårdare att kunna tolka och förstå den enskilda individens sätt att uttrycka önskningar och behov. På samma sätt riskerar vårdares budskap att missförstås. Om vårdaren misslyckas att förstå den boendes kommunikation och vice versa, kan det leda till situationer med utmanande beteende exempelvis i form av vägran, verbal eller fysisk aggressivitet.Syfte: Det övergripande syftet med avhandlingen är att studera interaktion mellan vuxna personer med utvecklingsstörning och vårdare i gruppbostäder, samt att studera effekter av en utbildningsintervention för vårdare som arbetar i gruppbostäder.Metod: Avhandlingens samtliga delstudier har genomförts i gruppbostäder för personer med utvecklingsstörning bland boende och vårdare i ett län i norra Sverige. I studie I insamlades data kring 556 personer med utvecklingsstörning. I studie II och III deltog 16 vårdare och 11 personer med utvecklingsstörning. I studie IV deltog 7 vårdare. Studie I bygger på personalens skattningar av funktionsnivåer och förekomst av begränsningsåtgärder. I Studie II och III utgörs data av videoobservationer och narrativa intervjuer. I studie IV användes flera datainsamlingsmetoder i en mixed method design med både vårdarnas skattningar, med hjälp av instrument och semi-strukturerade intervjuer. Analys av materialet i studie II, III och IV har gjorts med kvalitativ innehållsanalys och i studie I och IV har data analyserats statistiskt.Resultat: I studie I framkom att av 556 boende hade 99 (18%) varit föremål för fysiska begränsningsåtgärder under den senaste veckan. Av dessa 99 hade nästan alla varit föremål för mer än en typ av begränsningsåtgärd. Den vanligaste begränsningsåtgärden var bälte i stol (74%). Användningen av begränsningsåtgärder var relaterade både till fysiska funktionsnedsättningar och till beteende.I studie II reflekterade vårdare över videoinspelad interaktion där vårdarna medverkat, både framgångsrik och misslyckad interaktion. Exempel på framgångsrik interaktion var att förstå tecken, kunna möta behov och hantera situationer med utmanande beteenden. Vårdarna reflekterade över att framgångsrik interaktion ledde till säkerhet, trygghet och självförtroende hos de boende. Vårdarna reflekterade även över de konsekvenser misslyckad interaktion fick i form av irritation, aggression och våld från de boende.I studie III studerades videoinspelad interaktion mellan 11 personer med utvecklingsstörning och 16 av deras vårdare. Verbal och icke-verbal interaktion identifierades. Fyra inspelade situationer valdes ut för att belysa framgångsrikt samspel. Resultatet visade att framgångsrikt samspel mellan personer med utvecklingsstörning och deras vårdare bland annat bygger på möjligheten att bekräfta varandra, dela vardagshändelser, ge tid och utrymme och på att använda ett kongruent och tydligt språk.I studie IV utvärderades effekterna av en web-baserad utbildningsintervention, vars syfte var att förbättra interaktionen mellan personer med utvecklingsstörning och vårdare samt att därmed reducera förekomsten av situationer med utmanande beteende. Resultatet visade att vårdarna hade förbättrat sin förmåga att hantera situationer med utmanande beteende och att förekomsten av utmanande beteende minskat. Vårdarna beskrev att den web-baserade utbildningen upplevts givande och möjlig att ta del av parallellt med arbetet.Slutsats: Fysiska begränsningsåtgärder förekommer i gruppbostäder för personer med utvecklingsstörning. Användningen av begränsningsåtgärder kan vara relaterade både till fysiska funktionsnedsättningar och till beteenden i samspelet mellan brukare och vårdare. Vårdare upplever användningen av fysiska begränsningsåtgärder svår och tröttande. Brott i kommunikationen mellan personer med utvecklingsstörning och deras vårdare kan leda till försvårad interaktion med risk för situationer med utmanande beteenden. När vårdare är framgångsrika i interaktionen med personer med utvecklingsstörning ger det tillfredsställelse både för de boende och vårdarna. Vårdarna upplever dock ofta hjälplöshet och osäkerhet i relation till hantering av situationer med utmanande beteende och efterfrågar utbildning. Web-baserad utbildning om interaktion med personer med utvecklingsstörning och utmanande beteende har i vår studie visat sig ge lovande effekter och bör vara möjlig att utveckla för både introduktion av nyanställda vårdare och för kompetensutveckling bland mer erfaren personal.

Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Work is always in progress, somewhere, in some form. In a historical perspective the view of work has changed, as have the contexts where work takes place. Still there are strongly rooted images of what work is – in the patterns of thought and material conditions.This book embarks from the idea that work is something both immaterial and material. It discusses work as a conception and cultural norm, but also as something very tangible and concrete.Researchers from an array of scientific fields have gathered together around these questions. The idea has been to twist and turn the conceptions of what work is and – embarking from one’s own discipline – to contribute new perspectives to this topic.

Tidskriftsartikel (refereegranskat)abstract
- Chemosignals are used by predators to localize prey and by prey to avoid predators. These cues vary between species, but the odor of blood seems to be an exception and suggests the presence of an evolutionarily conserved chemosensory cue within the blood odor mixture. A blood odor component, E2D, has been shown to trigger approach responses identical to those triggered by the full blood odor in mammalian carnivores and as such, is a key candidate as a food/alarm cue in blood. Using a multidisciplinary approach, we demonstrate that E2D holds the dual function of affecting both approach and avoidance behavior in a predator-prey predicted manner. E2D evokes approach responses in two taxonomically distant blood-seeking predators, Stable fly and Wolf, while evoking avoidance responses in the prey species Mouse. We extend this by demonstrating that this chemical cue is preserved in humans as well; E2D induces postural avoidance, increases physiological arousal, and enhances visual perception of affective stimuli. This is the first demonstration of a single chemical cue with the dual function of guiding both approach and avoidance in a predator-prey predicted manner across taxonomically distant species, as well as the first known chemosignal that affects both human and non-human animals alike.

Tidskriftsartikel (refereegranskat)abstract
- Background: There is limited information on the distribution of retroperitoneal lymph node metastases (LNMs) in upper tract urothelial carcinoma (UTUC).Objective: To investigate the location of LNMs in UTUC of the renal pelvis or proximal ureter and short-term complications after radical nephroureterectomy (RNU) with lymph node dissection (LND).Design, setting, and participants: This was a prospective Nordic multicenter study (four university hospitals, two county hospitals). Patients with clinically suspected locally advanced UTUC (stage >T1) and/or clinical lymph node–positive (cN+) disease were invited to participate. Participants underwent RNU and fractionated retroperitoneal LND using predefined side-specific templates.Outcome measurements and statistical analysis: The location of LNMs in the LND specimen and retroperitoneal lymph node recurrences during follow-up was recorded. Postoperative complications within 90 d of surgery were ascertained from patient charts. Descriptive statistics were used.Results and limitations: LNMs were present in the LND specimen in 23/100 patients, and nine of 100 patients experienced a retroperitoneal recurrence. Distribution per side revealed LNMs in the LND specimen in 11/38 (29%) patients with right-sided tumors, for whom the anatomically larger, right-sided template was used, in comparison to 12/62 (19%) patients with left-sided tumors, for whom a more limited template was used. High-grade complications (Clavien grade ≥3) within 90 d of surgery were registered for 13/100 patients. The study is limited in size and not powered to assess survival estimates.Conclusions: The suggested templates that we prospectively applied for right-sided and left-sided LND in patients with advanced UTUC included the majority of LNMs. High-grade complications directly related to the LND part of the surgery were limited.Patient summary: This study describes the location of lymph node metastases in patients with cancer in the upper urinary tract who underwent surgery to remove the affected kidney and ureter. The results show that most metastases occur within the template maps for lymph node surgery that we investigated, and that this surgery can be performed with few severe complications.

Workplace intervention for improved risk perception and preventive activity among workers : using hand-held vibrating machines: a pilot study
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This article presents a pilot study of a 1-h workplace educational intervention implemented among ten construction workers who were highly exposed to hand–arm vibration. The intervention combined risk communication and normative expert advice intended to reinforce preventive behaviour related to vibration, noise, and biomechanical loads. Data for this study comprised intervention notes and interview data from interventionists, and pre- and post-intervention interview data from participating workers.The results suggested that the intervention was sensitive to disturbances and should be directed only to motivated workers possessing sufficient self-efficacy, and only in circumstances in which exposure may be controlled on the local workplace level and by locally implemented measures. Unless these conditions are present, the studied intervention may fail to influence preventive behaviour, and may instead cause cognitive dissonance and frustration among participants and interventionists.

- Contagious disease is a major threat to survival, and the cost of relying on the immune system to defeat pathogens is high; therefore, behavioral avoidance of contagious individuals is arguably an adaptive strategy. Animal findings demonstrate the ability to detect and avoid sick individuals by the aid of olfactory cues, and a recent study indicated that human axillary odor also becomes more aversive as a function of immune activation. By injecting healthy human participants with lipopolysaccharide (0.6 ng/kg body weight) to experimentally induce inflammation, this study demonstrates that natural daily rhythms of urine odor-its perceived dimensions and volatile profile-are altered within hours of inflammation onset. Whereas healthy human urine decreases in averseness over the course of a single day, inflammation interrupts this process and results in an increased urine odor averseness and an altered volatile composition. These results support the notion that subtle and early cues of sickness may be detected and avoided, thereby complementing the immune system in its role of keeping us alive and healthy.

Human scent as a first-line defense against disease
- 2023

Ingår i: Scientific Reports. - 2045-2322. ; 13:1

Tidskriftsartikel (refereegranskat)abstract
- Individuals may have a different body odor, when they are sick compared to healthy. In the non-human animal literature, olfactory cues have been shown to predict avoidance of sick individuals. We tested whether the mere experimental activation of the innate immune system in healthy human individuals can make an individuals' body odor be perceived as more aversive (intense, unpleasant, and disgusting). Following an endotoxin injection (lipopolysaccharide; 0.6 ng/kg) that creates a transient systemic inflammation, individuals smelled more unpleasant compared to a placebo group (saline injection). Behavioral and chemical analyses of the body odor samples suggest that the volatile components of samples from sick individuals changed qualitatively rather than quantitatively. Our findings support the hypothesis that odor cues of inflammation in axillary sweat are detectable just a few hours after experimental activation of the innate immune system. As such, they may trigger behavioral avoidance, hence constituting a first line of defense against pathogens of infected conspecifics.

- Ability to detect diseases in conspecifics would be advantageous for the individual. In line with this, rodents avoid body odors of infected individuals. Two studies (Olsson et al. 20014; in prep.) indicated that this is possible by way of human smell and human observers. T-shirts from donors (worn for 4 hours) that had received an injection of endotoxin [0.8ng lipopolysaccharide (LPS) / kg body weight], which causes systemic inflammation, smelled more unpleasant, intense, and sick than shirts from donors that had received a placebo (Saline) injection. GC/MS analysis of the shirts suggested that the change of body odor was not due to a general increase of odorous compounds in the “sick shirts” compared to “placebo shirts” but rather to a qualitative change. Study 2 (ongoing) further investigated the nature of this perception. In a first experiment, we compared the body odor of 30 endotoxin (0.6ng LPS / kg body weight) and 21 placebo (Saline) donors. Again, body odors were sampled during 4 hours using T-shirts. Observers then smelled the shirts and rated intensity, pleasantness, and disgust. In a second experiment, urine from these donors were collected and was investigated in the same way with subjective ratings. Altogether the data suggest that systemic inflammation makes body odors more aversive within a few hours.

Disgusting odors trigger the oral immune system
- 2023

Ingår i: Evolution, Medicine, and Public Health. - : Oxford University Press. - 2050-6201. ; 11:1, s. 8-17

Tidskriftsartikel (refereegranskat)abstract
- Recent research has characterized the behavioral defense against disease. In particular the detection of sickness cues, the adaptive reactions (e.g. avoidance) to these cues and the mediating role of disgust have been the focus. A presumably important but less investigated part of a behavioral defense is the immune system response of the observer of sickness cues. Odors are intimately connected to disease and disgust, and research has shown how olfaction conveys sickness cues in both animals and humans. This study aims to test whether odorous sickness cues (i.e. disgusting odors) can trigger a preparatory immune response in humans. We show that subjective and objective disgust measures, as well as TNFα levels in saliva increased immediately after exposure to disgusting odors in a sample of 36 individuals. Altogether, these results suggest a collaboration between behavioral mechanisms of pathogen avoidance in olfaction, mediated by the emotion of disgust, and mechanisms of pathogen elimination facilitated by inflammatory mediators.Disgusting stimuli are associated with an increased risk of infection. We here test whether disgusting odors, can trigger an immune response in the oral cavity. The results indicate an increase level of TNFα in the saliva. This supports that disease cues can trigger a preparatory response in the oral cavity.

Unilateral Resection of the Anterior Medial Temporal Lobe Impairs Odor Identification and Valence Perception
- 2015
-
Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 6

Tidskriftsartikel (refereegranskat)abstract
- The anterior medial temporal lobe (TL), including the amygdala, has been implicated in olfactory processing, e.g., coding for intensity and valence, and seems also involved in memory. With this background, the present study evaluated whether anterior medial TL-resections in TL epilepsy affected intensity and valence ratings, as well as free and cued identification of odors. These aspects of odor perception were assessed in 31 patients with unilateral anterior medial TL-resections (17 left, 14 right) and 16 healthy controls. Results suggest that the anterior medial TL is in particular necessary for free, but also cued, odor identification. TL resection was also found to impair odor valence, but not intensity ratings. Left resected patients rated nominally pleasant and unpleasant odors as more neutral suggesting a special role for the left anterior TL in coding for emotional saliency in response to odors.
